The utility model provides a rear structure of a vehicle, which is cut in the number of the component parts and the weight and can effectively prevent the upper parts of the rear carlings from bending in the case of collision at the rear. Reinforcement pieces with cap-like sections combined with the cap-like section planes of the rear crossbeams form a case-like structure with enclosed sections in the back-forth direction and the vehicle width direction between the rear of the inner side of the lower edge beam and the vehicle frame crossbeam which connects the left and the right rear carlings. In this way the case-like structure with enclosed sections is rigid, and can prevent the bending of the upper parts of the rear carlings and match with the rigid part of the joint at the inner side of the lower edge beam and the rigid part of the joint of the vehicle frame crossbeam. The reinforcement pieces, even in miniature, can further improve the rigidity of the rear carlings, thus the utility model can realize the reduction of the reinforcement pieces both in number and weight, and can also effectively prevent the upper parts of the bent parts from bending in the case of collision.


Step-stress experiments are performed in this paper to investigate the degradation mechanism of an AlGaN/GaN high electron mobility transistor(HEMT).It is found that the stress current shows a recoverable decrease during each voltage step and there is a critical voltage beyond which the stress current starts to increase sharply in our experiments.We postulate that defects may be randomly induced within the AlGaN barrier by the high electric field during each voltage step.But once the critical voltage is reached,the trap concentration will increase sharply due to the inverse piezoelectric effect.A leakage path may be introduced by excessive defect,and this may result in the permanent degradation of the AlGaN/GaN HEMT.


Radio signal synthesis is considered for transmitting binary characters having a minimum level of out-of-band emission; the parameters of such signals are presented and it is shown that they provide a considerable reduction in the energy emitted outside the set bandwidth by comparison with standard ones.


We investigate the collapse and revival of first-order coherence in deep optical lattices when long-range interactions are turned on and find that the first few revival peaks are strongly attenuated already for moderate values of the nearest-neighbor interaction coupling. It is shown that the conventionally employed Gutzwiller wave function, with only on-site number dependence of the variational amplitudes, leads to incorrect predictions for the collapse and revival oscillations within the extended Bose-Hubbard model. We provide a modified variant of the Gutzwiller ansatz, reproducing the analytically calculated time dependence of first-order coherence in the limit of zero tunneling.


According to the best available commentary (Stern 1996), the 36th myth busted by Palaiphatos (concerning Herakles and a certain 'Philoites') is the only one too corrupt to understand, and also the only one about a myth unheard of elsewhere. I argue that it is really about 'Philoktetes', the well-known hero who lit Herakles' funeral pyre on Mount Oeta. (In Palaiphatos' interpretation, Herakles failed to cure himself by applying leaves, but Philoctetes treated him more successfully using cauterization.) This proves that Palaiphatos always chose popular myths, and especially those which his readers would know from the tragic stage.


A survey of the psychiatry of defective memory is given insofar as it deals with the viewpoints of informative psychology. I t begins with an introduction to the basic terms of the pathology of memory, which are clearly stated in the Table. Discussing pathological memory defects, special stress is laid on retrograde and other amnesias, twilight states, senile and presenile dementia, ALZttEIMER~S disease and KO~SAKO]~ disorders and their relationship to cybernetical theories of memory. In addition, the phenomena of oneminute-memory, hypermnesia, so called "Lebensbilderschau" (life panorama) and of memory changes by means of hypnosis are fully discussed.


The general electronic properties of solids containing narrow bands is explored. A typical example of such a solid at its most difficult is NiO which is insulating, independent of magnetic ordering, and has a narrow, partly filled, 3d Ni band and a broad, filled 2p O band. We approach the description of these solids from a best single determinant point of view and find, for NiO as an example, the O 2p bands best described by conventional energy band theory and the narrow Ni 3d levels by localized states (that is, a valence bond description). Calculations for NiO are performed in this limit using unrestricted Hartree-Fock techniques. The improvements needed are discussed and systematic techniques for their implementation described. The effect of such improvements is computed for NiO and an electronic structure for NiO is obtained, in reasonable agreement with experiment.


This paper presents an adaptive Power System Stabilizer (PSS) using an Adaptive Network Based Vague Inference System (ANVIS). An Adaptive Vague Set Based Controller Power System Stabilizer (AVCPSS) has been evaluated. This AVCPSS is capable of providing appropriate stabilization signals over a broad range of operating conditions and disturbances. A Vague Controller (VC) is synthesized by using the notion of vague sets, which are a generalization of fuzzy sets and synonyms of the interval type fuzzy set. In the proposed vague expert system, speed deviation and its derivative have been selected as vague inputs.


In this study, Howell et al. found that the ability of RUNX1 to promote endothelial-to-hematopoietic transition (EHT) depends on its ability to recruit the TGFβ signaling effectors AP-1 and SMAD2/3, which in turn is determined by the changing chromatin landscape in embryonic versus fetal ECs. Their work provides insight into the regulation of EndoMT and EHT that will guide reprogramming efforts for clinical applications.


There are four factors influencing the electrochemical properties of LiFePO4/C cathode material,including the molar ratio of Li/Fe,the quality of glucose,sintering time and sintering temperature.The synthesis of LiFePO4 via the improved solid-state reaction was optimized with orthogonal tests and LiFePO4/C with an excellent electrochemical performance was synthesized under this optimized conditions.Without using ball milling,this improved solid state reaction method was propitious to the industrial production.The properties of optimized LiFePO4/C cathode material were systemically studied via the methods of XRD,SEM,and cyclic voltammetry electrochemical impedance spectra.The first discharge specific capacities of the optimized samples were 139.6 mAh/g at 0.1 C and 99.8 mAh/g at 2.0 C under room temperature.The capacity at 0.1 C went up and remained at 147.4 mAh/g and at 2.0 C,it dropped to 90.5 mAh/g after 30 cycles.


In many applications the image registration task turns out to be a fundamental prerequisite for any further processing and analysis. In the proposed paper a new efficient technique is presented, appropriate for registering images which are translated and rotated versions of a reference image. The technique consists of two main parts: an efficiently implemented prewhitening part, and an iterative part which yields the unknown displacements after a few iterations. The cross-correlation operations involved in the iterative part are performed efficiently via a new scheme based on a proper partitioning of the images and the use of the FFT. Note that this efficient scheme is also applicable to the conventional spatial cross-correlation method. The new registration technique exhibits a superior performance as compared to the conventional cross-correlation method.

Background This study aimed to determine the effect of in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), and individual factors on the sex ratio of offspring at birth in China. Methods This retrospective cohort study analyzed 6,700 infants (singletons and twins) who were born between December 2016 and December 2019 after fresh embryo transfer. The primary outcome measured was the secondary sex ratio (SSR) among live births. Results A total of 4,892 infants were born after cleavage-stage embryo transfer, and 1,808 infants were born after blastocyst-stage embryo transfer. The SSR for IVF was signi�cantly higher than that for ICSI (SSR = 113 :100 vs. 92:100, P < 0.05). Male infertility signi�cantly decreased the proportion of male offspring compared with non-male infertility. Multivariate logistic regression after adjusting for confounders revealed that neither the fertilization procedure nor the infertility cause had a signi�cant effect on the SSR. The SSR of blastocyst-stage embryo transfer was higher than that of cleavage-stage embryo transfer, but the difference was not signi�cant.


Objective: Data on effects of vitamins, hormones and neurotrophic factors on the etiology of attention deficit hyperactivity disorder (ADHD) and major depressive disorder (MDD) in children is limited. We hypothesized that serum vitamin D, brain-derived neurotrophic factor (BDNF), leptin, and leptin receptor levels are different in these patients, and that aforementioned biomarkers may affect symptom severity and risk of suicide.
Methods: This study included 33 ADHD, 29 MDD patients and 35 healthy controls. The Turgay DSM-IV-Based Child and Adolescent Disruptive Behavioral Disorders Screening and Rating Scale (T-DSM-IV-S) was used to assess the severity of ADHD, while Children Depression Inventory (CDI) and the Suicide Probability Scale (SPS) were used to measure the severity of depression and suicide risk in the MDD group. Serum vitamin D, BDNF, leptin, and leptin receptor levels were measured from participants' venous blood samples.
Results: Vitamin D and leptin receptor levels were significantly higher in the control group than in the patient groups, and leptin levels were significantly higher in the ADHD group than in the MDD and control groups. There was no difference between the groups in terms of BDNF levels. No significant correlations between ADHD duration, subtype, severity, depression severity, suicide risk, and vitamin D, BDNF, leptin, and leptin receptor levels were found.
Conclusion: Although current research supports that BDNF, vitamin D, leptin, and leptin receptor levels may be involved in the etiopathogenesis of MDD and ADHD, large-scale studies are needed to better evaluate the effects of these factors.


This week was a very good week for student lobbying in Ontario. The provincial g o v e r n m e n t made several announcements, including $310 million to support greater PSE access, along with $81 million to revamp student financial aid. Included in the aid reforms is a new interest-free grace period of six months before a recent grad must begin OSAP repayment, as well as the doubling of the OSAP income exemption. On the heels of so much lobbying success, the MSU will be addressing several broad issues as we push forward on a new lobbying agenda. The key components of our new requests are as follows: With both the Men's and Women's C a n a d i a n hockey teams winning Gold in Vancouver, hockey is as popular as ever. As a result, companies nationwide have tailored their efforts towards this market and hockey has become an even more potent business. Early in December, the McMaster Students Union (MSU) began discussion with The Skate's Edge; a sporting apparel company based in Calgary. Although talks are preliminary, Skate's Edge (SE) has requested the MSU's assistance with the building of a hockey rink on or near the McMaster University campus. The building would hopefully be accompanied by the return of both a McMaster Men's and Women's hockey team. The MSU has been approached for two main reasons; our relationships with both the City and the University, along with our youth-centered focus. After numerous failed attempts by various parties to relocate an NHL team to the GTA, Skate's Edge has what they believe to be a long-term solution aimed at marketing Hamilton as "The Real Hockey Town Canada." By focusing on Hamilton's youth and the students that comprise the three PSE institutions in the city (Mac, Mohawk and Redeemer), Skate's Edge hopes to build Hamilton into a lucrative hockey town. Herein lies the purpose of the MSU in this process. Skate's Edge has proposed the use the space that is currently occupied by Undercovers (MUSC B118) as a centre for apparel sales for current and future merchandise. Furthermore, it has been proposed that the MSU help facilitate discussion between City politicians, University administration and SE executives. It is expected that investments from all three parties will grant SE the necessary resources to build a rink, while simultaneously providing cultural incentives for graduate retainment in the city; a current priority for the City of Hamilton. This is a major endeavour that still has many factors left to be concluded. The current proposal depends on whether students would be interested in paying a potion of the costs of the facility and if the proposed site – the rugby field, expanding partially into


The Introduction shows that scholars disagree strongly about Thomas Hardy's creative abilities as a poet. To avoid this critical impasse, I limited the scope of my study to an aspect of Hardy's work about whose artistic value Hardy scholars agree: i.e., the inherent lyricism in Hardy's descriptions of nature. In Chapter 1, I study sixteen poems written by Hardy in which nature is either the principal or the sole subject of the poem and show that the nature section(s) may be isolated and stand on their own. In Chapter 2, I examine and versify some of Hardy's prose descriptions of nature to (1) show that some prose passages, like the nature sections in the poems discussed in Chapter 1, may be taken out of the whole and stand as a poem or prose narrative on their own and (2) bring their lyricism to the fore. The following excerpt from The Return of the Native (Gatrell 17) is an example of what I did: MY VERSIFICATION ORIGINAL TEXT PROSE There the form stood, There the form stood, motionless as the hill beneath. Above motionless as the hill beneath. the plain rose the hill, above the hill rose the barrow, above Above the plain rose the hill, the barrow rose the figure. Above the figure was nothing that above the hill rose the barrow, could be mapped elsewhere than on a celestial globe. above the barrow rose the figure, above the figure was nothing that could be mapped elsewhere than on a celestial globe. The strong rhythm given to this prose passage by the shortness of the sentences, the repetition of the words "above the" (rhetorical anaphora) and "rose the hill," "hill rose the barrow," "barrow rose the figure," "figure" (repetition and assonance) bring out Hardy's poetic intent and lyricism. In the Epilogue, I summarise the basic conclusions reached in the main body of the essay in regard to: (1) the role that Hardy's descriptions of nature play within the passages where they occur and (2) the most important syntactic elements found in Hardy's lyrical descriptions of nature. iii


The classic linear relationship of fertility rates, either in terms of completed family size or birth timing, to income fails to take adequately into consideration social variables, such as marriage rate, female unemployment rate, urban vs rural residence, divorce rate, and contraceptive sales levels. Even when only income is considered, its effect on fertility is not linear because the opportunity cost of children is high at both ends of a marriage -- during the 1st 2 years because income is low and during the last 6 years because income is high enough for other values, such as leisure, to compete with children. The relation between income and fertility is therefore parabolic. If one analyzes US census data from 1900 to 1977, the threshold level of permanent income at which the influence of income becomes negative is $2599. This value of permanent income occurs between 1958 and 1959, and the US birth rate began to decline in 1957. Income also affects fertility indirectly because it affects marriage rates and the timing of births. Divorce rates also affect fertility in 2 ways. They limit the completed family size of any 1 family, and they tend to have a conservative effect on risk-taking behavior, such as having children. Thus, increasing marriage rates have a positive effect on fertility; increasing divorce rate, a negative one. Female employment increases the opportunity cost of having a child, since a child may be considered as 1 kind of durable good, which competes for the woman's time. Migration from rural to urban areas also effects a decline in fertility. War affects fertility in at least 3 ways. It influences the number of men away, the number of men returning at the same time, and the amount of stress on a military family whether there is a war or not. What these various relationships indicate is that it would be premature to assume that as income increases fertility rates will necessarily decline. If the behavior of divorce and marriage rates remains stable and the rate of growth in permanent per capita income remains at 2.5%-3.0% per year, given the present age structure of the population, marriage rates, and thus fertility rates, will increase.


The specific problem this research addresses is how programmatic media buying (IAB 2013; Ebbert 2012) could help in designing effective mobile app advertisement campaigns. In particular, it is proposed that ad campaigns which target the mobile users via mobile applications would be more effective when there is a way to determine the audience information of mobile apps from which mobile ad requests are generated. In order to solve this dilemma, in this research it is proposed a dynamic approach which can effectively measure the audience demographics for the millions of existing mobile applications as well as the new incoming applications. There are mainly four steps involved with this research. First step is to generate top n categories for a given app A and estimate the set of app audience demographic properties (Age, Education & Has Children) based on the "category – audience demographic" mapping. In the second step it has been proposed a way to predict the gender demographics of mobile app users. In the third step, accuracy of predicted audience demographic values is evaluated. In the fourth step efficacy of using audience demographics data on a real mobile app ad-campaign will be evaluated. This research has progressed till step 3 and step 4 is remaining. Preliminary experiment of the proposed approach yielded satisfactory results. Since most of the ad-requests do not contain relevant audience information, proposed approach can be used to plug this data as a third party platform to the ad-requests. Given the popularity and usefulness of mobile apps, studies of this nature can greatly help many constituents of app eco system. As a next step (Step 4), the effectiveness of incorporating proposed programmatic buying framework on a real time mobile advertisement campaigns would be evaluated. For example, suppose an advertiser wants to design an ad campaign for a newly designed female fashion outfit then the proposed framework in this study can be utilized in numerous ways. Initially, using audience profiling of each app, advertisers can identify the apps which are mostly used by female users. Then the most popular female apps at a given time t can be identified by deriving the overall popularity of an app in time t. Subsequently, the ads campaign can be delivered through the set of identified apps. In order to measure the effectiveness of this programmatic buying framework in an ad campaign, several of experiments will be designed. First, an experiment will be designed with advertisements by only using app audience profiles, then a second experiment would be designed for the same ad campaign only using popularity signals and a third experiment would be designed, targeting the apps which are popular at given time t and being used mostly by female users. The practical efficacy of the programmatic buying framework will be validated against direct ad serving frameworks (i.e. nonprogrammatic buying) and programmatic buying without providing the additional info such as app audience profile information and app popularity signals. This way it can be estimated the effectiveness of each approach and combined approach in an ad campaign setting at a given time t.


The Plymouth Laboratory. The buildings, machinery and fittings have been maintained in a state of efficiency. An electric motor and pump have been installed for circulating the sea-water through the Aquarium and Laboratory tanks, and fresh provision has been made for the supply of air to the tanks. It is anticipated that the new arrangements will reduce considerably the running costs. The ejector used for pumping sea-water from the sea to the large reservoirs has undergone an extensive overhaul and is working efficiently. A small dynamo for the production of direct current for physiological work has been fitted in the engine room and is worked by the gas engine. As we are unable again to obtain the use of the room at the Corinthian Yacht Club for the Easter Classes in Marine Biology, the Council has decided to erect a class room at the back of the Laboratory, with dimensions 40 ft. by 16 ft. It is hoped that this will be completed by March, 1923. A considerable part of the sum necessary for this new building has been subscribed by former students and workers at the Laboratory.


Over the past three decades, the world has witnessed perhaps the most dramatic demographic and epidemiological transitions in China. During this period, the population of China has grown by a quarter of its size in 1990 to 1.41 billion in 2020 (1). Even though the fertility rate in China has experienced a sustained decline, mortality among the Chinese population has improved tremendously. Life expectancy at birth, a succinct summary index of overall mortality levels, has improved by 9.5 years to 77.6 years in 2019 (2). This is equivalent to an increase of a third of a year in life expectancy at birth for every calendar year in the past three decades, a feat rarely achieved by other countries at similar starting points. Such impressive improvements in all-cause mortality coincided with a shift in both levels and compositions of causes of death during the same period. This rapid epidemiological transition manifested in a fast shift of disease burden from communicable diseases to noncommunicable diseases (NCD), a continuation of health trends which started well before the 1990s. In 1990, about 12% of deaths in China came from infectious diseases. This proportion declined significantly to less than 3% in 2019. Meanwhile, the proportion of deaths due to NCDs increased by 17 percentage points to 90.1% in 2019 (3). With the continued improvement in economic conditions and general living conditions, it is safe to say almost all disease burden in China in the future lies in various diseases in the NCD category, a feature shared by all developed nations currently. With this shift in disease burden to NCDs and improvements in health care and medical treatment, an average Chinese citizen spends more years with lessthan-optimal health now compared to 1990. In 1990, the difference between life expectancy and healthy life expectancy (HALE) was 6.6 years. This gap has increased by about 40% over the past three decades to 9.1 years in 2019 (2). Such interconnections between improvements in population health and the challenges they present to both the public health and medical community requires rigorous research on the disease burden for precise and targeted health policy setting in China.


Not only facial expressions but also body gestures and postures play an important role in non-verbal communication. Whilst evidence shows that affective standing postures account for at least four affective dimensions - arousal, valence, potency and avoidance - it is not clear if the same is true for sitting postures. In addition, whilst there is a large body of work investigating cross-cultural differences in the perception of facial expressions, there is very little work on the cross-cultural perception of body expressions. We investigated the minimal universality and cross-cultural difference in the perception of sitting postures and the body descriptors that guide these perceptual processes. Japanese body postures were collected and measured through conventional sensors. Japanese and British observers were recruited for the cross-cultural study. The results show that, for Japanese observers, the three dimensions of arousal, valence and dominance were necessary to account for most of the variance in the perception of the set of affective postures whilst, for British observers, only valence and arousal were necessary. An analysis of the body descriptors highlighted a few differences in the way these were associated with affective dimensions. It also showed that, for Japanese observers, the rating of dominance was modulated by the position of the legs, arms and trunk.


This paper studies the stress-strain relationship of rock in the process of loading and unloading. Taking sandstone as an example, conventional triaxial loading and unloading experiments are carried out. The non-linear characteristics of rock during the post-peak unloading stage are analyzed, and the damage variable of rock is defined. An elastic modulus model for describing the stress-strain relationship during post-peak unloading is presented. The relationship between the axial strain and the radial strain in the loading-unloading process is analyzed; the Poisson's ratio model in unloading process is obtained. The D-P plastic model is introduced to modify the hardening function according to the plastic hardening characteristics of sandstone; a damage model associated with equivalent plastic strain is established. The computational model is matrixed and then calculated numerically. In the process, the following conclusions are drawn: (1) The porous rock shows obvious non-linear characteristics during loading. With the increase of body stress, the elastic modulus of rock increases gradually. (2) When the axial stress is greater than the confining pressure in the process of unloading rock after peak load, Stress-strain can be described by multiplying the elastic modulus model of the pre-peak elastic stage by the continuity factor. (3) With the increase of equivalent plastic strain, Poisson's ratio increases first, then decreases, and finally tends to be stable. In the post-peak unloading process, the equivalent plastic strain does not change, while the Poisson's ratio remains unchanged. The results show that the proposed model can reflect the stress-strain law of rock during post-peak unloading.


This paper presents an algorithm to distinguish whether the output label that is yielded from multiclass support vector machine (SVM) is true or false without knowing the answer. Such judgment is done only by the confidence analysis based on the pre-training/testing using the training data. Such true/false judgment is useful for refining the output labels. We experimentally demonstrate that the decision value difference between the top candidate and the second candidate is a good measure. In addition, a proper threshold can be determined by the pre-training/testing using only the training data. Experimental results using three standard image datasets demonstrate that our proposed algorithm can improve Matthews correlation coefficient (MCC) much better than simply thresholding the decision value for the top candidate.


A survey of coal-burning utilities indicates confidence that coal stockpiles will enable them to continue supplying electricity during a two- to three-month coal strike unless winter weather is too cold. Stockpiles of more-expensive spot-market coal have raised electricity prices for some utility districts. Contacted for this survey were: Ohio Edison, Central Area Power Coordinating Group, East Central Reliability Group, Dusquesne Light Co., Pennsylvania Power and Light, Delmarva Power and Light Co., Baltimore Gas and Electric, Monongahela Power Co., Cincinnati Gas and Electric Co., New York State Electric and Gas Co., Niagara Mohawk Power Co., Public Service Co. of New Hampshire, and the New England Power Pool. The utilities reported adverse situations due to wildcat strikes, frozen barges, confusion in coal prices, and, for some, a lack of fuel-adjustment clauses. (DCK)


Due to increasing usage of the haptic modality in virtual reality applications, the perceptual aspects of the interaction between haptic and auditory modalities is becoming more important. In our daily life, force‐feedback which we perceive in our hands after beating a drum as well as the loudness of the drum sound give us the required information about how much force we have applied when playing a drum. In this study, psychophysical experiments were conducted to investigate the effect of loudness on the haptic force‐feedback perception (strength) by playing a virtual drum. Subjects were presented (1) only haptic force‐feedback information, (2) only auditory information, and (3) auditory and haptic information together. In each experiment, subjects were asked how much force they had applied when playing the virtual drum. The results show that the magnitude of strength increases with increasing loudness in spite of no change in force‐feedback as generated by a virtual drum and applied to the subject's hand. These results contribute to our knowledge on how to effectively combine haptic and auditory information in virtual environments. [Work supported by IGSN, Ruhr University Bochum.]


Abstract : Electromechanical suspension actuators are devices intended to provide the force input called for by motor vehicle active suspension systems. Experimental active suspensions have been devised, in which hydraulic actuators provide the force input. Such systems leave much to be desired regarding safety to equipment and personnel. In addition, hydraulic actuators require an electromechanical valve to interface the electrical and hydraulic aspects of the overall system. Accordingly, electromechanical actuators are being studied as an alternative approach to active suspension design. Such actuators would provide a direct interface between electrical/electronic controls and the suspension dynamics, eliminating the need for hydraulic systems and their attendant problems of leakage and vulnerability to battle damage. The report that follows, describes the reason for studying electromechanical actuators, requirements such devices must meet, and various development programs. In addition, this report also describes various electric motor and actuator concepts that could serve as a point of departure for future electromechanical actuator development.


United State Treasury Bonds are government bonds issued by the United State Treasury through the Public Debt Bureau. The trades of U.S. Treasury Bonds have a huge influence on global economy. To analysis the trend of global economy, many economists believe U.S. Treasury Yield has the ability to predict the fluence of other financial markets such as stock market, futures market, Option market, etc. However, However, most financial prediction models focus only on predicting stock price, which is a sort of multidimensional time-series prediction. Although U.S. Treasury Yield could be viewed as a multidimensional time-series, the prediction models for predicting stock price are not able to completely satisfy the requirements for predicting U.S. Treasury Yield. Besides, most traditional machine learning methods focus only on estimation of short-term cash flow. As the result, the loss of traditional machine learning methods would significantly be increased while the period of prediction target is fluctuated. In this paper, we propose a Deep-Learning framework, DeepBonds, to build a prediction model to predict U.S. Treasury Yield with different issue period. Meanwhile, the Recurrent Neural Network with Long Short Term Memory (LSTM) architecture is utilized for effectively summarizing U.S. Treasury Yield as characteristic vectors. Based on the produced characteristic vectors, we can precisely predict future U.S. Treasury Yield with different issue period. We conduct a comprehensive experimental study based on a real dataset collected from the website of Resource Center of U.S. Department of The Treasury. The results demonstrate a significantly improved accuracy of our Deep Learning approach compared with the existing works.


Objective
To investigate the metabolic changes induced by cerium oxide (CeO2) nanoparticles in ulcerous wound tissues of diabetic GK rats using non-target metabolomics.

Methods
Twenty male GK rats with 8-10-week age and (256±3) g weight were randomly divided into normal saline group (10 rats) and CeO2 nanoparticles group (10 rats). Two skin lesions with a diameter of 8 mm deep to the muscle layer were created symmetrically on both sides of the spine of the dorsal scapulae of the rats. The wounds were administered with saline or CeO2 nanoparticles daily for 7 days, and the rats were sacrificed on day 7 for HE staining and metabolomics analysis. Liquid chromatography-mass spectrometry was used to detect the changes of metabolites in rat wound tissues, and differential metabolites were screened by principal component analysis and orthogonal partial least squares discriminant analysis.

Results
Compared with the normal saline group, the HE staining in the rats of CeO2 nanoparticles group had fewer inflammatory cells and more regular fibroblasts. A total of 15 different metabolites and 6 metabolic pathways that were significantly interfered with the experimental conditions were screened, including purine metabolism, glycine, serine and threonine metabolism, arachidonic acid metabolism, biosynthesis of unsaturated fatty acids, pantothenate and CoA biosynthesis and citrate cycle.

Conclusions
Nano-cerium oxide can significantly improve the wound healing by regulating glucose, lipid and amino acid metabolism of the metabolic network in GK rat wounds, and up-regulating the signaling pathways of anti-inflammatory and anti-oxidative stress.

This study examines the impact of the COVID-19 pandemic on sectoral stock prices in Nigeria stock market using daily data covering from February 28, 2020 to June 26, 2020. Applying the autoregressive distributed lag (ARDL) bounds test, the study finds that COVID-19 pandemic had adverse impact on the stock market indices in the short run. Furthermore, the study documents negative response of sectoral stock prices to the pandemic while the stock prices of the banking sub-sector are the worst hit. Compared to the consumer goods, and industrial subsector indices, the speed of adjustment to long run equilibrium is faster for the banking, subsector. Results from sensitivity analysis also indicate that the stock market responds negatively to the pandemic when the number of confirmed COVID-19 deaths is used. However, the stock market performance is more sensitive to the total number of confirmed cases than the total number of confirmed deaths. This implies that the market responds quickly to the pandemic. This paper, therefore, concludes that the COVID-19 pandemic had negative and heterogenous impacts on sectoral stock prices in Nigeria during the first wave of the pandemic.

A mineral oil micro-emulsion as agricultural chemical for preventing and eliminating diseases and pests is proportionally prepared from mineral oil, insecticide, solvent, emulsifier, and the aqueous solution of co-emulsifier. Its advantages are broad spectrum, and high effect and safety.


B eijing News has been the focus of press professionals, academics, and officials in China ever since its launch in 2003, for its courageous indepth journalism and its innovative business model in a country of strict state control over the media. Aiming to be the best newspaper in China over the last decade, it achieved a very high and widely accepted reputation for such a young news outlet. This reputation is now at risk. With the increasingly tightened press control in China in recent years, the paper's editorial and management teams have undergone restructuring on several occasions, under orders from above. Most recently, in August 2017, its publisher and founder Dai Zigeng was replaced by a local propaganda official. This move was followed by the resignation of several senior editors including its Editor-in-Chief Wang Yuechun and deputy chief editor Zhu Xuedong, effectively declaring the end of the independent road for the paper, and for the ''golden era" of news media in China.


In December 2019, cases of pneumonia of unknown origin occurred in Wuhan, China. In less than a month, the epidemic has spread rapidly. The World Health Organization (WHO) named this new strain of virus as "2019 Novel Coronavirus" (COVID-19). ), and convened an emergency committee to classify this as a "Public Health Emergency of International Concern, PHEIC" in accordance with the International Health Regulations (IHR).


The performance of the basketball game at the present time requires a lot of distinctive motor duties for the individual and collective performance of the players, and because of the extreme accuracy of this game in the use of plans and skills by coaches in order to develop methods of playing, all of these have necessarily imposed that changing the means of numbers of basketball players in proportion to With the speed of performance during the match, as well as making appropriate decisions to the requirements and changing situations that occur on the field. The problem of the research lies in that the problems facing specialists in the training process is how to measure mental abilities and give them digital values that help the specialist to employ them, and the lack of accurate objective tests that depend on measuring them on electronic devices, as well as "that if these tests are found, they do not have standards The coach was able to assess the player's immediate condition. In addition, the process of giving a value to the mental process is an important process that helps the coach to choose the player during the match and the nature of the competition.


No corporate asset today is at once so prized, and yet so poorly managed as the imagination and creativity of a company's people, But, at a time when companies have restructured themselves and improved quality, in the new competitive arena, the company that manages creativity most effectively performs best in the market. Ideas are the DNA of everything worthwhile, and companies everywhere are waking up to the power of creativity. This book explains how to engage the minds, stimulate the imagination and ensure the loyalty of people who design, build and deliver products and services. With specific examples, he shows how organizations fail by not making use of creative resources whilst other companies gain enormous advantage, transforming imagination into hard profit and a competitive position.


Two marine fishes, Japanese sea bass and red sea bream, were exposed to dietary tributyl tin(TBT)for two weeks to examine its immunotoxicity in relation to their body burdens. TBT body burdens of test fishes were also compared to TBT body burdens of their wild and cultured counterparts to predict their immune function inhibition. TBT concentrations of both fishes were significantly increased when dietary TBT concentrations were increased. While one of the non-specific immune responses, phagocytosis by neutrophil was not inhibited by TBT, another response, NBT reduction as a measure of oxidative burst of both fish species was inhibited even in the lowest dietary TBT concentration. Reverse sigmoid curve relationships were observed between inhibition of oxidative burst and TBT body burden in both fish species. TBT concentrations of some wild sea bass and cultured red sea bream were higher than the observed TBT concentrations of the lowest concentration exposure group of the present study. These results suggest that non-specific immune response of wild sea bass and cultured red sea bream can be inhibited by TBT contamination.


The traditional approach to studying American photojournalism explains the what and who of photojournalism - what events and developments occurred, what notable images were taken, and who took them. Without neglecting those concerns, "American Photojournalism" emphasizes the why. It explains how contemporary photojournalism is grounded in three large ideas: the desire to witness and record historical events and important people, the belief in photography's power to advance social justice, and the embrace of a universal humanism. Cookman argues that contemporary photojournalists are strongly influenced by these three ideas, and that these ideas have become the central tenets of the profession.


The stereocontrolled synthesis of goniothalesdiol A, a dihydroxylated tetrahydropyran compound, has been accomplished using D-ribose as chiral precursor. The key steps involved are aryl Grignard reaction, stereoselective alkoxy-directed keto reduction, and intramolecular oxy-Michael addition.


This paper investigates a number of healthcare centers in Turkey namely Hacettepe University, Gazi University, Zonguldak Karaelmas University Medical Schools and State Hospitals, Baskent University Medical School and Private Research Hospitals, and the Safranbolu State Hospital. The sound levels present in these centers were compared with number international as well as Turkish standards (1-4) . Research was carried out in the following way: Firstly physicians and nurses were surveyed by means of a questionnaire. Then, the hospital buildings were examined in terms of their architectural design features. Lastly, sound levels were measured in the consequent spaces where questionnaires were also conducted. A similar survey made in Johns Hopkins Hospital (5) back in 2005 had revealed that surgery patients in recovery were found to require additional medications due to sound levels being high Minckley (6) (over 60 dB at re 20 μPa). No significant difference was observed in terms of staff performance with or without the presence of sound. In another research, Murthy et al found that speech efficiency and short-term memory declined in the presence of typical operating-room noise among anesthetists (7). He also found that speech recognition declined by 23% and speech thresholds were increased roughly by 25% for the same level of comprehension -a result with important implications for medical safety. In addition, noise in hospitals can be detrimental as it helps to present their environment as quiet and peaceful. The World Health Organization (WHO) provides guidelines for hospitals in this respect in its Guidelines for Community Noise published in 1995 (4). These guidelines recommend an Lmax of no more than 40 dB (A) (at referenced (re) 20 μPa) at night time measured on the fast mode. They also suggest patient room Leq of no more than 35 dB (A) during the day. ANSI (The American National Standard Institution) (1) S12.2, published in 1995, recommends a maximum Room Criterions Curves (NCC) value ranging from 25 to 40 depending on the room type, and a maximum Noise Criteria Balanced (NCB) value ranging from 25 to 40.

Parsimony in signal representation is a topic of active research. Sparse signal processing and representation is the outcome of this line of research which has many applications in information processing and has shown significant improvement in real-world applications such as recovery, classification, clustering, super resolution, etc. This vast influence of sparse signal processing in real-world problems raises a significant need in developing novel sparse signal representation algorithms to obtain more robust systems. In such algorithms, a few open challenges remain in (a) efficiently posing sparsity on signals that can capture the structure of underlying signal and (b) the design of tractable algorithms that can recover signals under aforementioned sparse models.


The modification of the Electroweak Model with 3-dimensional spherical geometry in the matter fields space is suggested. The Lagrangian of this model is given by the sum of the free (without any potential term) matter fields Lagrangian and the standard gauge fields Lagrangian. The vector boson masses are generated by transformation of this Lagrangian from Cartesian coordinates to coordinates on the sphere S3. The limiting case of the bosonic part of the modified model, which corresponds to the contracted gauge group SU(2; j)× U(1) is discussed. Within framework of the limit model Z boson and electromagnetic fields can be regarded as external ones with respect to W-boson fields in the sence that W-boson fields do not effect on these external fields. The masses of all particles of the Electroweak Model remain the same, but field interactions in contracted model are more simple as compared with the standard Electroweak Model.

The Estonian Emotional Speech Corpus was created as an acoustic basis for synthesis of emotional speech. The present state of the Corpus enables an assessment of the choices made for its underlying theoretical model: whether it was justified to use non-acted speech and whether a difference has been established between the sentences where emotion is carried by voice only and those where sentence content may have influenced emotion identification.


The identification, segmentation, and detection of the infected area in brain tumor is a tedious and a time-consuming task. The different structures of the human body can be visualized by an image processing concept, an MRI. It is very difficult to visualize abnormal structures of the human brain using simple imaging techniques. An MRI technique contains many imaging modalities that scan and capture the internal structure of the human brain. This article concentrates on a noise removal technique, followed by improvement of medical images for a correct diagnosis using a balance contrast enhancement technique (BCET). Then, image segmentation is used. Finally, the Canny edge detection method is applied to detect the fine edges. The experiment results achieved nearly 98% accuracy in detecting the area of the tumor and normal brain regions in MRI images demonstrating the effectiveness of the proposed technique.


Rutherford back-scattering (RBS) and Medium Energy Ion Scattering (MEIS) have been used todetermine the lattice site occupancy of antimony (Sb) implanted into silicon (Si) and strainedsilicon (sSi) for ion energies of 2keV to 40keV. After annealing in the range 600-11000C forvarious times, Hall effect measurements were used to provide a measure of the percentageelectrical activity. A comparison of the lattice site occupancy with the percentage electricalactivity was used to confirm whether the assumption that the Hall scattering factor is equal tounity is valid. Our results demonstrate that for 40keV implants the electrical activation is about90%. In the case of 2keV implants the electrical activation is lower and in the range 10-80%,depending on the ion fluence and annealing conditions. This reduction in activation for lowerenergy implants is a result of inactive Sb close to the semiconductor/native-oxide interface, orabove concentrations of 4.5x1020cm-3. Tensile strain facilitates the lattice site occupancy andelectrical activation of Sb in Si by raising the doping ceiling. For both 40keV and 2keV implants,we have carried out a comparison of RBS/MEIS and Hall effect data to show that for Sbimplants into both bulk Si and strained Si the Hall scattering factor is equal to unity withinexperimental error.


analysis of neoliberal politics in the 1980s and 1990s that had an impact on both labourmigration and shifting geographies of performance – not only of huapango arribeño but other Mexican genres as well. Chapters 4 to 6 approach the topic of 'sounds of crossing' from distinct angles: sound's capacity to negate politics of geographies, to transcend national boundaries, and to open up transnational spaces of living. These new spaces are filled with music and poetry capable of bridging communities, making them meaningful, offering them homes, as Chávez asserts in the conclusion of the book. Published in Duke's series Refiguring American Music, Sounds of Crossing challenges the idea of 'American' music as either White or Black: so-called Mexican or 'Regional Mexican' music (an umbrella label created by the music industry that subsumes various rural-derived Mexican genres popular in the U.S.) has been part of the US-American sonic landscape for a long time already. Chávez thus insists on a critical aurality, i.e.


This paper presents a survey of main applicable technical principles and mechanisms for adaptive camouflage in the visible (VIS) and infrared (IR) spectral ranges. All principles are described by their operation method and technical data such as the active spectral range, the degree and speed of adaptation, weight, power consumption, robustness, usability, lifetime, technology readiness level (TRL) etc.. The paper allows to compare the different principles and to assess them with regard to an application to an adaptive camouflage system.

Land disposal of domestic wastewater has been practiced on a large scale in Europe for several decades, mainly for the purpose of irrigating crops or pasture. Recently, however, spray irrigation, one form of land disposal, has taken on new dimensions as it is considered a means of disposal of wastewaters which heretofore have been discharged directly to streams or lakes. The paper is a review of the health and hygiene aspects of wastewater treatment or wastewater reclamation by spray irrigation. Although the discussion is limited to spray irrigation because of its current popularity among communities and sanitary engineers, many of the basic principles are applicable to the other methods of land disposal such as surface flooding and ridge and furrow irrigation. The following conclusions relative to the health and hygiene effects of spray irrigation land disposal of wastewater can be drawn: Many of the detrimental health and hygiene aspects of land disposal should be significantly reduced by proper wastewater pretreatment including secondary treatment, filtration, and complete disinfection. By choosing a land disposal site that has from 5 to 10 ft of continuous fine soil, biological contamination of ground water can be avoided. The probability of inhaling pathogenic aerosols near a spray irrigation site may be significant. If ponding results in spray irrigation areas, mosquito breeding is enhanced. In areas where land disposal is the first step in a water recycle program, total dissolved solids, sodium, and nitrate nitrogen buildup in the ground water supply can be a problem. (44 references.)


We will present on the status of a new NUV (3080 A) miniature SHS instrument for detecting the hydroxyl OD/OH isotope ratio remotely in diffused and faint targets such as cometary tails, comae, and planetary exospheres. Developing the SHS instrument has a wide significance to Astrophysics and Planetary science. SHS provides integrated spectra at high R, over a wide FOV in compact designs that offer the ability to make key science measurements for a variety of planetary targets. Many planetary objects that produce UV emissions are angularly extended low brightness targets, i.e., solar wind charge exchange emission, solar system planetary atmospheres and exospheres, mapping atomic emission, comets, and the interplanetary medium. SHS could be implemented on a dedicated SmallSat or ISS that can sit and stare at its target for a long duration of time that cannot be done from the ground or on big missions.

Since China implemented the policy of reform and opening-up to the outside world, the mechanism for the people's interests expression and integration with Chinese characteristics has gradually been established, that is the People's Congress system based on the democratic centralism instead of the interest group politics. This kind of mechanism not only plays the role of interests' expression for the masses, but also helps maintain social stability in China. However, there is also much room for improvement of this mechanism. And it is still an important task for China to continue exploring an appropriate mechanism with Chinese characteristics for the people's interests expression and integration.


Abstract A legislature's ability to engage in oversight of the executive is believed to derive largely from its committee system. For example, powerful parliamentary committees are considered a necessary condition for the legislature to help police policy compromises between parties in multiparty government. But can other parliamentary instruments perform this role? This article suggests parliamentary questions as an alternative parliamentary vehicle for coalition parties to monitor their partners. Questions force ministers to reveal information concerning their legislative and extra-legislative activities, providing coalition members unique insights into their partners' behaviour. In order to test our argument, we build and analyse a new dataset of parliamentary questions in the British House of Commons covering the 2010‒2015 coalition. As expected, government MPs ask more questions as the divisiveness of a policy area increases. Legislatures conventionally considered weak due to the lack of strong committees may nevertheless play an important oversight role through other parliamentary devices, including helping to police the implementation of coalition agreements.

This paper deals with the application of gompertz curve model to mobile user growth. gompertz growth curve is a kind of product life cycle theories, which reveals the development of product markets has a sigmoid growing process. The gompertz curve model which can be transformed, employ ordinary least-squares principle to simply formula. Based on historical data, the initial formula can be projected. In order to achieve better prediction accuracy,0.618 optimal seeking methods can be employed to optimize Model ,which adjusts limit parameters of gompertz growth curve for the purpose of fitting actual data. Although the gompertz model establishment for Postal and Telecommunication Services is demonstrated in this paper, this model can be applied in many fields. Example programs for specifying these models based on the use of the gompertz Curve Model are also provided. So the gompertz model is effective path to the research of product life cycle theories, which the prospect of application will be promising.


In this paper, we introduced the optimal control homotopy perturbation method (OCHPM) by using the homotopy perturbation method (HPM). Every one, by using of the proposed method, can obtain numerical solutions of mathematical modeling for cancer-immunotherapy. In this paper, in order to prove the preciseness and efficiency of the OCHPM method, we compared the obtained numerical solutions with HPM. The results obtained showed that the OCHPM method is powerful to generate the numerical solutions for some therapeutic models.


The PRI created the IFE in 1990 to appease the discontent electorate after the party rigged the 1988 presidential election. Nevertheless, during the 1990s, the IFE quickly evolved as an important political check to the PRI's power. The IFE's path toward greater autonomy and control over the electoral system resulted from a series of PRI concessions to growing opposition parties and public demand for democratic elections.1 The IFE was the perfect tool to soften the PRI's fall from power, yielding political influence to other parties through elections without dismantling the party itself. From 1990 to 1994, the PRI had a close relationship with the IFE: the secretary of the interior served as secretary general of the IFE, and the majority of councilors were Congress members or party faithfuls. The outbreak of the Zapatista movement in 1994, however, created widespread political and social instability ahead of that year's presidential elections. As a response to this unrest, an eight-party opposition coalition in Congress voted to change the composition of the IFE's General Council, giving six nonpartisan "citizen" councilors the majority of power on the new 11-member board.2 In 1996, Congress passed yet another reform to give the IFE full independence from the executive branch, placing a nonpartisan "citizen" as president of the General Council. EXECUTIVE SUMMARY


Objective To explore the effect of rosuvastatin on serum lipids and high sensitive C-reactive protein(hs-CRP) in aged patients with coronary heart disease(CHD) and hyperlipidemia. Methods Seventy-two patients with CHD and hyperlipidemia were investigated by case-control study.They were randomly divided into treatment group and control group(each n=36).The patients in the control group received conventional therapy,while the patients in the treatment group were given rosuvastatin 10 mg/d for 8 weeks in addition to the conventional treatment.The levels of serum TC,TG,LDL-C,HDL-C and hs-CRP were observed before and after the treatment. Results After 8 weeks of treatment,the levels of serum TC,TG,LDL-C and hs-CRP in the treatment group were decreased significantly,while the level of HDLC was increased(P0.05).After 8 weeks' treatment,the levels of TC,TG,LDL-C and hs-CRP in the treatment group were significantly lower than those in the control group,meanwhile,the level of HDL-C in the treatment group was higher than that in the control group(P0.05).Before and after the treatment,all these indicators in the control group showed no statistically significant difference(P0.05). Conclusions Rosuvastatin can decrease the levels of serum TC,TG,LDLC,hs-CRP and increase the level of HDL-C in aged patients with CHD and hyperlipidemia.

The Belt and Road Initiative (BRI) aims to increase connectivity between regions and countries that market forces excluded from the previous wave of economic globalization. Foreign direct investment (FDI) can create the conditions for the economic takeoff of least-developed countries (LDCs) and developing countries. Although Chinese FDI has nearly doubled since the launch of the BRI in 2013 compared to 2005–2013, it does not seem to be directed toward BRI member countries more than the non-member countries. One exception is South American BRI member countries, which have significantly increased their FDI inflows from China. This is not the case, however, for West Asian countries, where FDI growth has been lower for BRI countries than for the West Asian countries as a whole, and especially for sub-Saharan BRI countries, for which the amount of FDI has even decreased compared to the 2005–2013 period. The BRI's slow start and the countries' gradual entry may explain the delay in seeing the positive results expected from it reflected in the data.


Mineral supplements are helpful for strong bones and the immune system plays an important role in postmenopausal stimulation of bone loss. This study examined the effect of calcium‐deficiency diet on immune functions and cell viability in ovariectomized rats (OVX). The treatments were as follows: Group 1, sham/AIN‐93M diet(0.5% Ca diet); Group 2, low‐Ca diet (0.25% Ca);Group 3, OVX/AIN‐93M diet; and Group 4, OVX/low‐Ca diet (0.25% Ca). The treated rats were sacrificed after 10 wks. In vitro lymphocyte proliferative responses and NK cell activity were measured in pooled spleen from each group. The mitogenic activity of lymphocytes in the spleen was slightly reduced in low‐Ca diet group. Ovariectomy caused a little decrease in the tumoricidal activity of NK cells, whereas low‐Ca diet resulted in the increase of tumoricidal acitivity. Ovariectomy caused the decrease of reactive oxygen species and NO production by macrophages. In contrast, low‐Ca diet induced the increase of tumoricidal activity. Moreover, ovariectormy marginally increased cell viability, whereas cell viability was reduced in group receiving low‐dose Ca supplement. Cell death was more pronounced in OVX on low Ca diet. Overall, our data suggest that calcium status of the animal has a differential effect on the function of immune cells.

Background: In the recent years, a new treatment modality, high-flow nasa l cannulae (HFNC) has become widely used despite limited systematic evaluation. Objective: To survey the attitudes and practices in academic neonatal units in the United States regarding the use of HFNC and to review the current literature on HFNC. Methods: A questionnaire regarding HFNC use was distributed to all (n = 97) Neonatal-Perinatal Medicine Fellowship Training Program Directors in the United States. Results: Fifty eight (60%) program directors responded to the questionnaire. Of these 40 (69%) reported using heated humidified HFNC (HHHFNC) and 18 (31%) not using this modality. Reported starting flows ranged from 1 to 6 L/min and maximal flows from 2 to 8 L/min. The indication for use of HHHFNC varied between units. Conclusions: The findings of our survey and our review of the literature sug gest that the use of HHHFNC is widespread despite lack of evidence of efficacy from large clinical trials. The i ndications for HHHFNC and the initial, minimal and maximal fl ows varied widely among the centers. This report supports the need for well designed randomized controlled clinical trials to evaluate the efficacy and safety of HHHFNC for a variety of clinical ind ications.


Growing demand for ultra-thin woven composites has been identified in weight-sensitive applications, especially in space engineering applications such as self-deployable structures. They undergo extreme curvatures during folding and deployment process and hence understanding their mechanical behaviour is important for optimization of future structures. Literature on experimental studies unfolds that there is a considerable reduction in bending stiffness of these ultra-thin woven composites when subjected to curvatures. This paper presents a numerical investigation that incorporates inter-tow and inter-lamina interaction behaviour on the homogenized response of a two-ply plain woven carbon fibre composite. Two distinct models were used in the analysis with dry fibre approach and resin embedded geometry. The analysis is advanced further towards the non-linear regime to predict the response under higher curvatures. It is shown that the developed models are capable of capturing the reduction in flexural stiffness.

The author approaches the unhappy consciousness thesis –present in modern philosophy– from Los Heraldos Negros (1918) of the peruvian poet Cesar Vallejo. One of Vallejo's greatest discoveries is that nature has been stripped of the divine; in other words, that God is dead. The concept of God as negation of man and the death of this God calls morality into question and leads to a type of nihilism which, paradoxically, seeks for some sort of divinity and trascendence. Vallejo moves towards this direction: towards an irreligious religiosity that recovers its religiousness in the new life of the spirit, towards a suffering God intimately close to man.


With the aim to reduce the dimensionality without sacrificing classification performance, the author gains insights from attribute reduction based on discernibility matrix in rough-set theory and proposes two text feature selection algorithms, i.e., DB1 and DB2. The experimental results indicate that DB2 not only yields much higher accuracy than information gain when the number of features is smaller than 6000, but also incurs much smaller CPU time than information gain.


Challenged economically, politically, socially, ideologically and geopolitically, Saudi Ara bia is confronting the perfect storm. How it weathers the storm will depend on how it handles the two most existential threats it faces: the rivalry with Iran for hegemony in the M iddle East and North Africa (a battle it ultimately will lose), and the inevitable restructuring of the in creasingly problematic marriage between the House o f Saud and the Wahhabi clergy, propo nents o f a puritan interpretation o f Islam on whom the ruling Al Saud family rely for their


Signal size usually dominates the speed and precision of a signal-separation practice.In order to balance between a reasonable speed and precision,the determination of a proper concerned signal size is usually a problem.A signal separation method through channel-parameter estimation based on correlation analysis and a ratio concept of signal size to one signal period are introduced.By doing a number of experiments on signals with different signal size ratio,the relationship between signal-separation precision and signal size ratio is approximate to an exponential function.On condition that signal size ratio is more than or equal to two,the accuracy of signal-separation satisfies requirement of engineering application.This result also adapts for precision analysis of correlation-value computing and other algorithms based on correlation computing,such as time-delay estimation,signal matching.


Summary To determine the relative importance of lactose caramelization in the browning of evaporated milk, uniformly labeled lactose was added to milk samples before sterilization. The CO 2 produced in the browning reaction was recovered as BaCO 3 and its specific activity was determined. It was found that about 4% of the total CO 2 produced by sterilization of milk at 242° F. for 15min. can be traced to caramelization of lactose.


Employee recruitment is a critical process in which organizations actively utilize recruitment sources in order to attract the best potential candidates to fill open positions. Previous research into recruitment sources have increased significantly in the past several years but have primarily focused on post-hire outcomes. Research on pre-hire outcomes may lend opportunities for corporate recruiters to be able to predict the quality of potential job candidates before being hired. Drawing on the importance of recruitment sources and pre-hire outcomes, this study investigates the possibility of predicting applicant personality traits from their job search strategies. A total of 226 participants completed an online survey that measured both their personality traits and their job search behaviors. Results found that several job search strategies did indeed correlate with certain personality traits but did not support all hypothesized correlations.


Object alignment is an activity frequently performed in several domains. Traditional AR/VR methods provide virtual guides such as text, arrows, or animations to assist users during alignment. This work explores the feasibility of using virtual cameras and mirrors instead. We conducted a study where participants aligned objects assisted by virtual cameras and mirrors in VR. Data regarding alignment, time to completion, users' distance traveled, average head velocity, usability, and mental effort was collected. Results show that virtual helpers reduce mental effort and distance traveled and increase acceptance without negatively affecting alignment accuracy.

The coordinated development of the regional economy is the key to finishing our country and building great task of well-to-do society in an all-round way. Our country every area incongruity basic place lie in low developed area and between the developed area, disparity between town and country expand constantly. The enlargement show as peasant absolute number of income increase, but relative to count growth even drop slowly directly, its basic reason lies in the base figure of peasant's population is too big. Keep coordination between every area lying in the existing productivity condition a bit more thoroughly at present, do the best to keep the disparity between every area no longer expanding further, and make great efforts to create the condition, narrow the gap. Reduce peasant's population rationally and safely and effectively, its most effective way is to implement " the echelon immigrant ".

The objective of this technical paper is to present a method that characterizes autonomous vehicle (AV) safety performance through the application of risk-based validation that leverages existing crash incidence and severity data, physics based model and simulation, and U.S. Federal Motor Vehicle Safety Standard (FMVSS) benchmark metrics. The output of the proposed risk-based methodology is a framework that organizes the number and type of physical tests and model/simulation runs necessary to provide meaningful evidence of AV safety performance statistically equivalent to human-driven non-exempt motor vehicles.


In order to encourage a shift from the car to the more sustainable transport mode of cycling, cycle streets have been implemented in cities all over the world in the last few years. In these shared streets, the entire carriageway is designated for cyclists, while motorized traffic is subordinated. However, evidence on the impact of cycle street interventions related to travel behavior change has been limited until now. Therefore, the objective of this study was to evaluate whether cycle streets are an effective measure to facilitate bicycle use and discourage car use, thus contributing to the aim of promoting sustainable travel. For this purpose, we conducted a written household survey in the German city of Offenbach am Main involving participants affected by a cycle street intervention (n = 701). Based on two stage models of self-regulated behavioral change (SSBC), we identified the participants' level of willingness to use a bicycle frequently and to reduce car use. By means of bivariate and multivariate statistical methods, we analyzed the influence of awareness, use, and perceptions of the cycle street on the willingness to change behavior towards more sustainable travel. The results show that the intervention has a positive impact on frequent bicycle use, while we observed only a limited effect on car use reduction. Traffic conflicts and car speeding within the cycle street adversely affect the acceptance of the intervention. The study's findings provide new insights into the actual effects of a cycle street and its potential to encourage sustainable travel behavior.


The link between the evolution of atherosclerosis and endothelium derived NO synthesized by endothelial NOS (eNOS) is long acknowledged since endothelial dysfunction (that is the deterioration of endothelium dependent NO release) is a viewed as the forerunner of atherosclerosis. Additional to this a novel insulin sensitizing mechanism was described that is also linked to NO dependent mechanisms e.g. the activation of nNOS and is able to enhance the insulin sensitivity of striated muscle. There exists yet a third isoform of NOS, the inducible isoform (iNOS) that yields the highly reactive peroxynitrite. The different effect of these three distinct isoforms of NOS came into the focus of our attention due to the identification of a novel endogenous nitric oxide synthase inhibitor the asymmetrical dimetlyarginine (ADMA). ADMA inhibits the three isoforms with different kinetics. Within the frame of our research on one hand we investigated if the simultaneous inhibition of eNOS and nNOS is able to contribute to the evolution of atherosclerosis and insulin resistance. On the other hand we assessed if the inhibition of iNOS is able to confer beneficial effect in a condition when the enzyme is probably induced e.g. in early-onset atherosclerosis We found that SDMA or rather the proportion of ADMA/SDMA (a more appropriate indication of the intracellular ADMA level) showed positive correlation with the HOMA index used for the characterization of insulin resistance, an effect that remained significant even after correction for confounders if only atherosclerotic patients were included in the analysis. On the other hand, we found that ADMA level negatively correlated with intima-media thickness a surrogate for cerebroand cardiovascular diseases, and this negative correlation remained significant even after correction for confounders.


Antioxidants were used to prevent oxidation process in foods which lead to rancidity and browning, DNA oxidation and have many positive physiological effects in human. The concentration and the absorption mechanism of natural antioxidants are important in obtaining the maximum beneficial effect. The sources of antioxidants must be carefully considered to maximize absorption and avoid the toxicity of higher concentration of synthetic groups. A general lack of information about antioxidants indicates by a survey of the general public. An organized effort to educate individuals about foods rich in natural antioxidants and the ability to recognize the major synthetic antioxidants on food labels would be highly beneficial, though more research needs to be done to fully understand their physiological effects.


Background and Objectives: The Gerbich blood group system comprises three high‐incidence antigens which have been localized on glycophorins C (GPC) and D (GPD) molecules. Murine monoclonal antibodies (mAbs) directed against Ge4 and Ge3 epitopes have already been obtained. We describe two murine mAbs (Z151.17 and J6) with Ge2 specificity. Materials and Methods: The mAbs were investigated by serological methods and immunoblotting, with common, Ge‐negative and enzyme‐modified RBCs. Results: Both mAbs behaved like anti‐Ge2 in serological tests, but bound to GPC and GPD on immunoblots. Z151.17 did not recognize the GPCYus or GPCGe variants, whereas J6 revealed a 25‐kD component from Ge:‐2,‐3,4 membranes, which is identical to the GPCGe molecule. Conclusion: These two mAbs are directed to slightly different epitopes. The Z151.17 and J6 epitopes are common to GPC and GPD, thus distinct from the Ge2 antigen defined by human alloantibodies.


Staff building is the soul of sehool-running level and education quality in institutions of higher learning.There are numerous ways of staff building,however,in the 21st century of globalization,sending outstanding teachers abroad to pursue their study is undo- ubtedly one of the essential and effective ways of enhancing staff building.This paper has put forward some considerations of doing well the work for people to study abroad in institutions of higher learning.


The threats to European security have become the subject of discussions and actions taken by states and NATO because of using military forces Russia's to change state borders after 2008. In response to the new situation, deterrence, building national and strategic resilience to military and non-military threats have gained importance again. It was especially true regarding NATO's eastern flank as being directly threatened by the possibility of hybrid and potentially military engagements. The article aims to present the implementation of deterrence and strategic resilience concepts, especially concerning the activities of NATO and the Baltic countries. A preliminary assessment shows that the arrangements are adequate but require further actions and investments. The article was developed utilizing qualitative methods of analysis, synthesis and case study referring to the theory and practice of the deliberated issues.


Objective: The aims of this study are to determine the incidence of TIA-related infarcts, to estimate the independent predictors of evidence of the infarcts, and to investigate the correlation between stroke risk and the findings of magnetic resonance imaging (MRI) including diffusion-weighted imaging (DWI). Background In accordance with the recent definition of transient ischemic attack (TIA) and the recommendations of the American Health Association (AHA), MRI including DWI is considered a mandatory tool in the evaluation and treatment of patients with TIA. Design/Methods: Over a 36-month period (starting November 2007), 1910 patients (mean age, 66.7±13 years; 46% women; median National Institutes of Health Stroke Scale (NIHSS) score, 0; interquartile range [IQR], 0-2) with a TIA from 15 hospitals of the stroke registry (Quality of Treatment of Stroke in Schleswig-Holstein [QugSS2]) were investigated with MRI including DWI. Results: A TIA-related acute infarct was detected in 206 (11.1%) of 1862 patients. The following predictors were estimated by logistic regression: paresis (OR, 1.5; 95% confidence interval [CI], 1.0 to 2.1; P=0.02), aphasia (OR, 1.2; 95% CI, 0.8 to 1.9; P=0.3), NIHSS score ≥10 (OR, 3.6; 95% CI, 1.9 to 7.0; P Conclusions: Clinically useful predictors can help clinicians identify an acute infarct in patients who admitted with transient neurological symptoms. Disclosure: Dr. Al-Khaled has nothing to disclose. Dr. Eggers has nothing to disclose.


"Pathways to Historical Knowledge" was the title of the CORD regional conference where these papers were first presented (California State University, Northridge, December 8, 1979). In this conference, two disciplines – dance ethnology and criticism – and one genre – the personal memoir – were looked at in relation to what they could contribute to the study of dance history. In the session "Historical Process and Ethnic Dance Research," these papers and the ensuing discussion made it clear that the dance ethnologist may be as concerned with process through time as the dance historian. The ethnologist however, working in the field and in social relationships with informants, almost inevitably influences the development of the dance complex under study – a well known phenomenon in any research involving living human subjects. The nature and amount of this influence seems from these accounts to depend on the extent to which the researcher has or develops such social relationships with members of the community whose dance is being investigated. The community may even go so far as to consider the researcher or the written results of research as its authority when making judgments or decisions about its own dance. Understanding the change and the continuity in seemingly traditional dance cultures thus becomes a difficult task: the researcher is a part of the dynamic process and yet must try to interpret it objectively and keep his own influence to a minimum.


Three aquatic macrophytes viz. Eichhornia crassipes, Pistia stratiotes and Lemna gibba were
studied for their potential to remove heavy metals from Flashlight manufacturing industry effluent.
Plants were exposed to 100%, 75%, 50%, 25% and 0% (distilled water) concentration of effluent
for 5 weeks. Results revealed that the macrophytes under study were highly efficient in the
removal of Hg, Mn, Zn and Pb. Translocation factor expressed that metals were largely retained
in the roots of Pistia stratiotes and Lemna gibba while Eichhornia crassipes concentrated most
of the metals in shoots. Analytical results showed that Eichhornia crassipes removed
approximately 67.535, 89.30, 80.84 and 69.80% of Hg, Pb, Zn and Mn, respectively, from 100%
concentrated effluent which shows its higher metals removal efficiency compared to Pistia
stratiotes(65.44%, 87.109%, 70.23%, 63.242%) and Lemna gibba (71.84%, 89.074%, 70.97%,
73.97%,), respectively. These plants were also subjected to toxicity assessment and no symptoms
of metal toxicity were found. Therefore, these macrophytes can be applied on the large scale
treatment of waste water where volumes generated are very high and concentrations of pollutants
are low.


Nowadays, Taiwan is influenced by the trend toward democratization and the publics'open-minded to political thinking. Besides, each media channels are popular and well-developed. These phenomena make candidates have to think about how to break through the traditional election mode under competitive political environment. Among many candidates, they will use more efficient marketing strategies to get approvals from voters rather than the past simple campaign activities. This research aimed at the 2010 Taipei mayor election which is based on the case of candidates of KMT and DPP. Through watching the election progress and visiting the campaign members which come from both side, to discuss the political marketing process of Mr. Hau Lung-bin and Mr. Su Tseng-chan. including the images of candidates and the presents of marketing strategies ,then compare the discrepancies between the both sides. The research noticed that both of candidates fully use the media channels to promote and propagate during the marketing process. They also use social media networks to deliver campaign information and communicate with net friends. In addition, we can see the beauties appear in normal business activities to promote advertise effects. Besides, there are also many beauties attend the campaign to attract the voters. Furthermore, both of the propagandas and campaign activities of political marketing from two sides show the diversity. It mainly weakens the political messages and uses more creative and active ways to promote and propagate the campaign activities.


Abstract : Physical fitness was assessed for 302 male and 393 female recruits (RCT) upon entry into and at the completion of RCT training using the Navy's Physical Readiness Test (PRT) consisting of 1.5-mile run time, sit-ups in 2 minutes, sit-reach distance, and percent of body fat estimation. Sit-ups performed in the first minute of the 2-minute test, and triceps skinfold thickness were also measured. Maximum number of pull-ups was measured for male, and flexed-arm hang time for female RCTs. RCT fitness was compared to American Alliance for Health, Physical Education, Recreation and Dance (AAHPERD) national norms for 17 year old high school students (AAHPERD) where possible, as well as to PRT scores from a sample of active duty Navy personnel (AD). It was concluded that inadequate normative data on civilian populations, and technical constraints in study administration make interpretation of the comparisons with civilians difficult. It was clear that RCT training improved the physical fitness of RCTs. Finally it appears that RCT training graduates enter the fleet somewhat more fit than fleet sailors.


The monitoring of silvicultural quality in eucalyptus clonal plantations is essential to check the quality of forest operations. The uniformity of a stand is considered a fundamental variable to the monitoring. It shows potential improvements in silvicultural practices, enabling increases in stand uniformity and yield. Today, Unmanned Aerial Vehicle (UAV) images are underutilized and have been shown to be a powerful tool in forest monitoring. The main goal of this work was to develop a model to identify the tree' crowns and create a uniformity evaluation method in clonal eucalyptus plantations through the use of UAV. 50 plots of 50m x 20m were allocated within the study area using the ArcGIS 10.1 software. The maximum likelihood classification tool was used, dividing the image in two classes, tree and non-tree. It was then transformed into polygons and the area of the crowns were calculated. The Pvar50 was used as a uniformity index for the crown areas. The result was a low uniformity index (31, 5%) and high fail index (10, 2%), which can be explained due to possible failures in forest activities or drought that occurred after the planting period. The evaluation of the UAV images proved to be a powerful tool to check the silvicultural quality of the stands. In order to get a good maximum likelihood classification, a high image quality it required.

For a hierarchy of properties of term rewriting systems related to termination we prove relative undecidability: For implications X → Y in the hierarchy the property X is undecidable for term rewriting systems satisfying Y. For most implications we obtain this result for term rewriting systems consisting of a single rewrite rule.


Various strains of Escherichia coli were grown to a titer of 5 × 108 cells/ml in peptone media. Following osmotic shocks (peptone water 0.4 M sucrose) or lysozyme-EDTA treatment in hypertonic media, the spheroplasts were stored at 4° and then tested for competence with OX 174 and M 13 phage DNA and M 12 phage RNA. Lysozyme spheroplasts proved most effective and yielded the following maximum infectivities: for one O× 174 DNA molecule, 5 × 10−3 infectious DNA centers; for one M 13 DNA molecule, 10−5 infectious DNA centers; and for one M 12 phage RNA molecle, 2 × 10−5 infectious RNA centers. For many spheroplast preparations competence remained nearly constant for one week. One strain, E. coli 112–12 (λh)F+, retained a constant (though low) level of competence for months when frozen in 10% (v/v) dimethyl sulfoxide.

O× 174 DNA saturation experiments indicated that 0.05–1% of the lysozyme spheroplasts were competent. Between 12 and 20 minutes after the addition of a non-saturating level of 32P-labelled O× 174 DNA to such competent cell populations at 37°, 10–20% of the label was adsorbed. Noncompetent cell populations adsorbed no more than 4% of the added label. Prolonging the DNA adsorption time did not give a higher efficiency of DNA infection, because the cells began losing competence through a temperature-dependent process.

More than 90% of the infectious O× 174 DNA centers reamined sensitive to DNAase during the first 20 minutes in DNA adsorption medium. Plating O× 174 DNA and M 12 RNA-infected cells on eosin methylene blue agar during this period prevented the formation of phage, whereas the plaque-forming ability of the mature phage was not inhibited. These observations may suggest an unusual permeability of the competent cells.

Inhibitors of phage RNA infection were removed by washing the competent cells. DNAase pretreatment of the spheroplasts increased their competence for infectious M 12 phage RNA.


Synopsis Methods are now available for the complete solution of stresses and displacements within and beneath embankments. These methods are either experimental or numerical, involving recourse to a digital computer with all the necessary ancillary work. For the engineer wishing to calculate the possible settlements and lateral deformations beneath an embankment, using his slide-rule together with some tables and charts, there is at present no other alternative but to make over-simplifying assumptions that may lead to unnecessarily high errors. In this Paper a semi-empirical method is presented which, it is hoped, will narrow the gap between intricate computational work and intolerable inaccuracy in the study of deformations beneath embankments. Actuellement il y a des methodes pour une solution complete des contraintes et des deplacements aussi dans le remblai ou sous le remblai. Cependant ces sont des methodes experimentales ou numeriques necessitant l'emploi de calculateur electronique avec tous les tr...


Abstract Rocky tide pools are transition environments whose communities are affected by sudden temperature, salinity and nutrient fluctuations. Furthermore, these environments are exposed to multiple stressors and can be easily altered by human trampling. In particular, specific studies on rock pool heterobranchs communities are lacking for the Mediterranean Sea. In this study, the community of Heterobranchia (Mollusca: Gastropoda) living in an anthropized rock pools system in western Adriatic (Ancona, Italy) has been investigated and a first checklist of the sea slugs in this urbanized areas is provided. During the four months survey, a total of 452 specimens, belonging to 19 species and 12 families was recorded. Notable findings were the first record of Placida dendritica for the Conero Riviera, and the first records of Doto cervicenigra and Ercolania viridis for the western Adriatic Sea. Identification of trophic categories showed a diversified assemblage in terms of food sources mirroring a surprising species diversity. Moreover, we provide here the description of a peculiar behavior possibly used by sea slugs to cope with the stressful conditions within this semi-closed system.


Transfer functions are used to model the short-term response of daily municipal water use to rainfall and air temperature variations. Daily water use data from nine cities are studied, three cities each from Florida, Pennsylvania, and Texas. The dynamic response of water use to rainfall and air temperature is similar across the cities within each State; in addition the responses of the Texas and Florida cities are very similar to one another while the response of the Pennsylvania cities is more sensitive to air temperature and less to rainfall. There is little impact of city size on the response functions. The response of water use to rainfall depends first on the occurrence of rainfall and second on its magnitude. The occurrence of a rainfall more than 0.05 in./day (0.13 cm/day) causes a drop in the seasonal component of water use one day later that averages 38% for the Texas cities, 42% for the Florida cities, and 7% for the Pennsylvania cities. In Austin, Texas, a spatially averaged rainfall series shows a clearer relationship with water use than does rainfall data from a single gage. There is a nonlinear response of water use to air temperature changes with no response for daily maximum air temperatures between 40° and 70°F (4–21°C) an increase in water use with air temperature beyond 70°F; above 85°–90°F (29°–32°C) water use increases 3–5 times more per degree than below that limit in Texas and Florida. The model resulting from these studies can be used for daily water use forecasting and water conservation analysis.


Evidence for the Wanzlick equilibrium between carbene 1 and dibenzotetraazafulvalene (1)(2) at ambient temperature has been found (see scheme). Enetetramines of type (1)(2) can also be cleaved by coordinatively unsaturated transition metal compounds to form dicarbene complexes.

Summary form only given.In the early 90's, the experimental evidence of frequency doubling in the 1,3,5-trinitro-2,4,6-triaminobenzene (TATB) crystal based on the simplest octupolar extension of paranitroaniline, has triggered the opening of a broader molecular engineering avenue, whereby symmetry-ensured cancellation of the molecular dipole moment is shown to be compatible with non-zero and significantly larger /spl beta/ tensor coefficients than for the purely dipolar scheme. Moreover, earlier one-dimensional (1D) systems have been embedded in the broader realm of multipolar systems whereby the quadratic nonlinearity of any molecule can be decomposed in rotationally invariant dipolar and octupolar components. Full exploitation of the tensorial character of /spl beta/ has thus permitted to enlarge the pool of candidate molecular structures to more isotropic two-dimensional 2D and three-dimensional 3D multipolar systems, whereas a n-level model (where n>2) has been shown to adequately describe the frequency dispersion of multipolar /spl beta/ tensors.
