TheAnalyze of variable cross-section bars systems has deserved certain attention for the specialists in this matter. Since several years ago, there has been a few professionals who have been done some effort about the analytic representation of the variable cross-section members modeling. Only they have proposed and they have usedpractical methods that sometimes are quite coarse due to the simplifications they have involvedthis, maybe for having a justification for using some of the Computer programs that are very well-known, which inelude constant cross-section bars in their bookstores. Nowadays, there are only a few commercial programs which have the treatment of cases of vari able cross-section bars, even though, since many years ago, an appropriate formulation has been presented based on the beams theory, with the application of flexibilities method for obtaining rigidity coefficients of three-dimensional elastic variable cross-section bars, and that conjugated beam for obtaining fixation turns and fixed-end moments. In this formulation it is established the need of carrying out the algebraic integration through out the whole bar, this can be quite complicated or tedious if the cross-section of the bar has some variations in its dimensions. Taking the flexibility coefficients, and the rigidity coefficients with the fixed-end moments in vari able cross-section bars, it could be an example for the numeric integration application. Because of this, in this paper I show, in summary, the results of the flexibilities method applied for obtaining tlióse flexibility coefficients, and the application of Simpson rule (1/3) for the numeric evaluation of the integral. With practical purposes I developed a Computer program that incorporales the numeric integration for obtaining, the flexibility coefficients, the elastic rigidities and fixed-end moments of three-dimensional variable cross-section bars, all of those are very important and useful for an Structural Analysis for this kind ofbars, using this program we were able to solve some examples whose results were compared with other Solutions that used another criteria and tools, there are commonly used in these researches. Some of these examples are included in this repon.


This paper introduces architectures for a large aperture telescope for space astronomy using a Fresnel optic as the primary. Systems built around Fresnel optics hold the possibility of drastically reducing mission costs. The use of a Fresnel optic allows a light weight primary lens which results in lighter systems, which in turn can be flown on smaller, less expensive launchers. Costs are also reduced in the manufacture of the primary lens. The performance of the telescope was given and the tolerancing of the system discussed. The key issue of mitigation of the intrinsic chromatic aberration is discussed in detail. It was shown that architectures based on Fresnel optics can be considered viable and should be considered in the technology selection for future missions


Molecular dynamics simulations are performed to estimate acoustical and optical phonon relaxation times, dispersion relations, group velocities, and specific heat of silicon needed to solve the Boltzmann transport equation (BTE) at 300 K and 1000 K. The relaxation times are calculated from the temporal decay of the autocorrelation function of the fluctuation of total energy of each normal mode in the ⟨100⟩ family of directions, where the total energy of each mode is obtained from the normal mode decomposition of the motion of the silicon atoms over a period of time. Additionally, silicon dispersion relations are directly determined from the equipartition theorem obtained from the normal mode decomposition. The impact of the anharmonic nature of the potential energy function on the thermal expansion of the crystal is determined by computing the lattice parameter at the cited temperatures using a NPT (i.e., constant number of atoms, pressure, and temperature) ensemble, and are compared with experimental values reported in the literature and with those computed analytically using the quasiharmonic approximation. The dependence of the relaxation times with respect to the frequency is identified with two functions that follow the functional form of the relaxation time expressions reported in the literature. From these functions a simplified version of relaxation times for each normal mode is extracted. Properties, such as group and phase velocities, thermal conductivity, and mean free path, needed to further develop a methodology for the thermal analysis of electronic devices (i.e., from nano- to macroscales) are determined once the relaxation times and dispersion relations are obtained. The thermal properties are validated by comparing the BTE-based thermal conductivity against the predictions obtained from the Green–Kubo method. It is found that the relaxation times closely resemble the ones obtained from perturbation theory at high temperatures; the contribution to the thermal conductivity of the transverse acoustic, longitudinal acoustic, and longitudinal optical modes being approximately 30%, 60%, and 10%, respectively, and the contribution of the transverse optical mode negligible.

For permission for commercial use of this work, please see paragraphs 4.2 and 5 of our Terms Abstract: This study aimed at identifying the levels of adaptive problems among teenage female refugees in the government schools and explored the behavioral methods that were used to cope with the problems. The sample was composed of 220 Syrian female students (seventh to first secondary grades) enrolled at government schools within the Zarqa Directorate and who came to Jordan due to the war conditions in their home country. The study used the scale of adaptive problems that consists of four dimensions (depression, anger and hostility, low self-esteem, and feeling insecure) and a questionnaire of the behavioral adjustment methods for dealing with the problem of asylum. The results indicated that the Syrian teenage female refugees suffer a moderate degree of adaptation problems, and the positive adjustment methods they have used are more than the negatives.


A field experiment entitled "Effect of inorganic fertilizers in combination with biofertilizers on nutrient content and uptake of kharif maize" was conducted at Agriculture College Farm, Bapatla, during both kharif 2020 and 2021. The experiment was laid out in randomized block design (RBD) with seven treatments and replicated thrice. The treatments consisted of T1- Control; T2- 100% RDF; T3- 125% RDF; T4 – 100% RDF + VAM; T5- 100% RDF +VAM + Azospirillum + PSB; T6- 75 % RDF + VAM; T7- 75 % RDF + VAM + Azospirillum + PSB. During kharif in two years of study significantly higher nitrogen content and uptake was recorded with 125 % RDF (T3) it was on par with 100% RDF + VAM + Azospirillum + PSB (T5) and 100% RDF + VAM (T4). The maximum nitrogen content and uptake was significantly influenced due to various level of inorganic fertilizers. Higher phosphorus, potassium and sulphur (non-significant) content and uptake were recorded in the treatment T5 that received 100% RDF +VAM + Azospirillum + PSB and it was on par with treatment which received 75 % RDF + VAM + Azospirillum + PSB (T7), 125 % RDF (T3) and 100% RDF + VAM (T4) at knee high, tasseling and harvest stage of maize. The results revealed that application of biofertilizers along with inorganic fertilizers significantly increased plant nutrient content and uptake of maize crop.


Background. The South African National Blood Service participated in the Recipient Epidemiology and Donor Evaluation Study (REDS-III) multicentre study between 2011 and 2019. The goal of this partnership was to perform cutting-edge research in transfusion medicine while at the same time building a broad base of local research capacity. This is a challenge in low- and middle-income countries such as South Africa (SA) for multifactorial reasons. Objectives. To evaluate the outcome of the research capacity-building initiative. Methods. The REDS III study provided multiple opportunities for local research participation in projects designed to reduce the impact of HIV on the SA blood supply. Research capacity building initiatives included research training courses in SA and internationally for promising junior SA investigators under the separate Fogarty International HIV training grant. In addition, junior researchers were provided with ongoing mentorship and collaborative interactions with experienced researchers. Research outputs directly and indirectly linked to REDS III are described. Results. Over a 9-year period, the following research capacity building was accomplished: the core study team of 12 staff were trained in the responsible conduct of research, 34 staff attended local research training and 6 young investigators were trained internationally in manuscript writing. Three staff developed a study database. Five staff expanded the existing biorepository. Sophisticated laboratory and clinical skills were taught to 9 staff to enable large leukapheresis collections and performance of specialised laboratory tests locally. A functional research office was established by 4 study members. A total of 91 abstracts were presented at international and national conferences. Twenty-three transfusion-related manuscripts have been published in reputable journals. Six staff attained further qualifications, of which an additional three are PhDs in progress. A long-term plan to establish a research academy at the SA National Blood Service (SANBS) has been initiated. Conclusion. Significant research capacity and output was established at SANBS through a successful North-South collaboration effecting blood transfusion safety in SA. Achieving sustainability was an early commitment, and has resulted in the establishment of a research academy and multiple local and international collaborations


On Deaf Ears: The Limits of the Bully Pulpit. By George C. Edwards, III. New Haven: Yale University Press, 2003. 320p. $35.00. The funeral of Ronald Reagan marked a celebration not only of the president's political accomplishments but also of the idea that the core of presidential leadership is mastery of the bully pulpit. Published shortly after Reagan was laid to rest, Bill Clinton's autobiography also reflects our modern preoccupation with rhetorical leadership. Clinton credits many of his political victories—most notably fending off an impeachment charge—to the power of rhetorical appeals. He also attributes many of his failures to an inability to communicate effectively. George Edwards thinks that Reagan, Clinton, and the conventional wisdom they exemplify are just plain wrong. In a thorough and forcefully articulated study, Edwards argues that public opinion is never altered by presidential speech. Efforts to advance a president's political agenda through rhetorical appeals over the heads of Congress to the people are futile wastes of time and energy.


A novel wireless video communication system is designed by improved video glasses and camera, which can ensure the user to have the feeling of being in the place of the other person in the communication process. The technical scheme is as follows: the user needs to wear processed transparent video glasses and a camera is placed in front of the user; the transparent video glasses are formed by adding a motion sensor to the common transparent video glasses; after the user wears the glasses, the motion sensor can capture the motion when the user turns the head; through the wireless communication system, on the one hand, the camera transfers the acquired image information to the transparent video glasses; and on the other hand, the motion sensor transfers the acquired data to the camera of the other person, thereby controlling the cameras to rotate by following the heads of the participants in the space of 360 degrees. Therefore, the user can experience the environment of the other person in an all-around manner.


Objective
To investigate children with nephrotic syndrome(NS) receiving long-term glucocorticoid treatment while monitoring insulin resistance(IR) index, and analyze the influencing factors, and to observe the efficacy of metformin for preventing glucocorticoid-induced obesity and diabetes mellitus type 2.

Methods
A total of 32 cases including 20 boys and 12 girls with mean age of 7.6 years old(2 to 14 years old), were diagnosed as NS.All children undergoing long-term treatment of prednisone>1 mg/(kg·d) for at least 3 months.The height, body weight and body mass index(BMI) were monitored.The concentrations of serum insulin and C-peptide were determined by radioimmunoassay, the concentrations of serum HbA1c were determined by high performance liquid chromatography, and the levels of fasting glucose, cholesterol and triglyceride were measured with an automatic measuring analyzer(American ABBO TT CCX-Ⅱ). The homeostasis model assessment-estimated insulin resistance(HOMA-IR) was calculated; When HOMA-IR>3.5, the patients were given metformin treatment for 12 weeks while supervising their height, weight, fasting blood glucose levels monthly.

Results
Out of 32 cases of NS with long-term use of prednisone, 23 cases had HOMA-IR>3.5(72%). Thus, IR group included 23 patients, and non-IR(NIR) group had 9 patients.There were significant differences between 2 groups in BMI, age, prednisone dosage and the levels of triglyceride(TG)(all P<0.05). After 12 weeks of metformin treatment, the HOMA-IR(5.24±1.82 vs 2.54±1.09, P<0.01), HbA1c levels[(6.36±0.82)% vs(5.39±0.51)%, P<0.05], BMI[(27.42±6.12) kg/m2vs(22.72±5.48) kg/m2, P<0.01], and TG levels[(2.03±1.10) mmol/L vs(1.45±0.48) mmol/L, P<0.05] were significantly reduced.

Conclusions
Older children with long-term use of glucocorticoid may easily lead to IR.Therefore, monitoring the HOMA-IR and early administration of metformin is helpful for prevention and treatment of glucocorticoid-induced obesity and diabetes mellitus type 2.

A metal–organic vapor phase epitaxy process of polarity inversion (PI) from Ga‐ to N‐polar is reported by exposing the Ga‐polar surface simultaneously to Mg and ammonia flows. This process differs from the conventional Mg heavy‐doping technique by intentionally predepositing a Mg‐rich thin layer on the Ga‐polar surface for PI. A full PI with a smooth surface in the subsequent GaN overgrowth is achieved by an exposure process for 900 s at 700 °C. Atomic force microscopy and piezo‐force microscopy characterizations reveal that the polarity change undergoes simultaneously with pyramid formation after ≈15 nm thick GaN overgrowth. The electron dispersion spectroscopy mapping of Mg indicates high Mg concentrations at the regrowth interface and in the PI domain boundary. A Mg‐rich thin layer is believed to cover the surface after the exposure process and release Mg dopants in the subsequent growth, leading to a high Mg incorporation in the GaN overlayer and therefore inducing PI. P‐type conduction with a hole concentration of ≈2.7 × 1017 cm−3 is achieved in the N‐polar GaN overlayer. It is also demonstrated that such a PI technique can be employed in the growth of a hybrid polarity structured ultraviolet‐light‐emitting diode with a reversed N‐polar contact layer on a Ga‐polar main body.

Latin American countries have evolved over the years. Still, after years of military reign, socioeconomic-instability, and civil wars, the region has been known for its anti-hegemonic economic growth (educational-policies) strategies. Central and South America's educational system has long been under investigation by researchers both theoretically and empirically. The transition of its education system through the introduction of centralized, liberalized, and populist ideology has sparked many researchers' interest. This paper aims to understand and compare 14 Latin American countries' education orientation. The study uses a matrix table to visualize the qualitative finding.


We consider the newly found high mass and low magnetic field binary pulsar PSR J1614-2230 in a model in which magnetars owe their strong magnetic fields to a high baryon density, magnetized core. In our magnetar model all neutron stars above a certain threhold mass are magnetars. This confronts us with the very basic paradox as to why this high mass star, PSR J1614-2230, remains a pulsar and shows no magnetar characteristics. This is a star that has acquired its large mass by accretion from its binary companion over 5 gigayears.
In this work we show that the maximum rate of energy gain from the strong interaction phase transition from this slow accretion does not allow for high enough interior temperature for ambipolar transport of the magnetic field to the surface of the star and thus the PSR J 1614-2230 remains latent and does not become an emergent magnetar.


We, in this paper, propose a kernel estimator of hazard ratio with censored survival data. The uniform consistency and asymptotic normality of the proposed estimator are proved by using counting process approach. In order to assess the performance of the proposed estimator, we compare the kernel estimator with Cox estimator and the generalized rank estimators of hazard ratio in terms of MSE by Monte Carlo simulation. Two examples are illustrated for our results.


Stochastic models for the origin and extinction of species have been rather neglected in applied probability. As an alternative to modelling speciation and extinction as intrinsically random, I shall describe and show simulations of a rulebased model. This involves mathematical representations of notions such as genetic type of species, environmental niche, fitness of a species in a niche, and adaptation. There are underlying random mechanisms for changes of niche sizes and for disconnection and reconnection of geographical regions, and these ultimately drive the evolution of species. Other approaches to mathematical modelling of evolution are briefly mentioned.


A series of Mn-Zn-O complex oxides catalysts supported on cordierite honeycomb were prepared by an impregnation method with using Mn (NO3) 2 and Zn (NO3) 2. The effects of the molar ratio on Mn and Zn, loading amount of Mn-Zn oxides, and calcinations temperature for the complete oxidation of toluene were investigated. The catalysts were characterized by specific surface area, scanning electron microscope (SEM), and X-ray diffraction techniques (XRD). Results showed that the Mn-Zn-O complex oxides catalysts with Mn and Zn molar ratio of 2, 10% loading and calcining at 450℃ exhibited high catalytic performance. With the concentration of toluene of 3.8 μg/m^3 and the gaseous hourly space velocity of 10000 h^(-1), the conversion of toluene was 91.4% at the reaction temperature of 300℃.

The subject of the study is a retrospective of the legal norms formation. Under these norms the prosecutor will be able to govern the issues of ensuring the legitimate interests of the state, society, business entities and the rights of citizens in resolving disputes in the field of economic activity. Chronological framework of research includes the period from the establishment of prosecutor's office in 1722 up to the collapse of USSR in 1991. The relevant legislation is analyzed. The author examines the scope of prosecutor powers in this sphere at different stages of formation and development of prosecution, and reveals the problems of determining the prosecutor's office place in the system of existing at that time bodies of state power. It is concluded that the prosecution authorities, since their creation in Russia and up to the present stage of development, taking a greater or lesser degree of participation in the resolution of disputes in the sphere of economic activity, played a significant role in the protection of exclusively state interests. The interests of society, business entities and citizens in the sphere of economic activity if there is a dispute were considered only through the prism of such interests. The hierarchy of interests of participants of economic activity in dispute resolution was unbalanced and built without taking into account the interests of all participants of economic relations.


The honey-guides (Indicatoridae) are brood parasites and specialist feeders on wax; the larger species obtain wax from bees' nests and the smaller ones from scale-insects or fruit (Friedmann 1955, Diamond 1985). The ability to digest beeswax has been demonstrated experimentally in only one bird species, the Lesser Honey-guide Indicator minor (Friedmann & Kern 1956a). Here we describe an experiment confirming the same ability in the Black-throated or Greater Honey-guide, 1.indicator, and discuss reasons for questioning Friedmann and Kern's claim that wax digestion in honey-guides need be accomplished hy symbiotic microorganisms.

The inherent vibration occurring due to compliance of Flexible Robotic System (FRS) provides numerous challenges to achieve accuracy at the end-effector of the FRS. This paper focuses on the study of influence of electronic control system hardware over electromechanical output of the FRS. The paper provides an insight to the relationship between drive current and motor torque with vibrations in the system. Design details of the novel indigenously-developed control electronics and, finally the controller of the prototype FRS will be reported in this paper, backed up by the glimpses of mechanical hardware. The performance and robustness of the prototype FRS will be finally discussed based on some representative analysis and results thereof. We will dis cuss about implementing various trajectory functions in the control program of the prototype FRS. The paper will further lead to modified linear trajectory where parabolic blends are introduced to reduce the infinite acceleration, which would eventually reduce the vibration in the links of the FRS. the three

The manuscripts are also primarily concerned with the history and literature of Maine, especially Kittery and Eliot, or with other areas of New England.


Distinct from the dynamical phase, in a cyclic evolution, a system's state may acquire an additional component, a.k.a. geometric phase. The latter is a manifestation of a closed path in state space. Geometric phases underlie various physical phenomena, notably the emergence of topological invariants of many-body states. Recently it has been demonstrated that geometric phases can be induced by a sequence of generalized measurements implemented on a single qubit. Furthermore, it has been predicted that such geometric phases may exhibit a topological transition as function of the measurement strength. Here, we demonstrate and study this transition experimentally employing an optical platform. We show the robustness to certain generalizations of the original protocol, as well as to certain types of imperfections. Our protocol can be interpreted in terms of environment-induced geometric phases.


Aimed at solving the problems of high energy consumption and frequently switching between forward and backward transportations in Ran-Jing Pipeline operation,the basic physical and rheological characteristics of Daqing crude oil mixed with Jidong crude oil were investigated.The optimum pour point depressant(PPD)for the mixed crude oil was selected,and the PPD concentration,heating treatment temperature and lowest one-direction oil throughput were confirmed.The one-direction operation schemes of Ran-Jing Pipeline by adding PPD for whole year and for seasons were also established,the pipeline security and econo-my in two-direction operation and one-direction operation by adding PPD were analyzed.


The interpersonal behaviors of 100 male batterers were investigated using Ryan's (1977) typological classification of the FIRO-B. The proportion of various types among batterers was compared to Ryan's VA and general population normative samples. Batterers were more likely to fall into categories of loner, rebel, and pessimist and were likely to be less outgoing, less intimate, and more cautious than the general population. The batterers demonstrated more difficulty with forming interpersonal relationships and expressing intimacy than the normative samples. The findings suggest that these individuals have difficulty in expressing affection and forming relationships and did not indicate that batterers in general have high needs to control others.


There are lots of words of "Wu + Abstract nouns." one of these is "Wuyi".One of the most popular dictionaries for Chinese is Xiandai Hanyu Cidian. This dictionary classifies "Wuyi" as a verb. However, I disagree with this classification.First of all, we can analyze verbs into transitive verbs and intransitive verbs . The former has the ability to take objects. "Wuyi" does not take objects. Consequently, it cannot a transitive verb.The alternative is that "Wuyi" is an intransitive verb. Generally speaking, intransitive verbs tend to be verbs related to an action or behavior. However, according to my research, "Wu + Abstract nouns" like "You + Abstract nouns" is not related with action or behavior. This suggests that "Wuyu" is not an intransitive verb.On the other hand, what "Wuyi" does describe are the properties of status of people or things. In doing so, it actually has the characteristic of an adjective.So, lots of dictionaries like Xiandai Hanyu Cidian, Xiandai Hanyu Fenlei Cidian, Xiandai Hanyu Changyongci Yongfa Cidian and others argue that "Wuyi" is an adjective. Despite this, there is another phenomenon. This is the adverbial usuage of "Wuyi". This kind of usuage is ubiquitous in Modern Chinese. Furthermore, "Wuyi" is mainly used adverbial , it also has the manner of speaking "Surely", "Certainly". This feather of "Wuyi" is deeply related with adverbs. So I argue that "Wuyi" can also be classified as an adverb.HSK Ciyu Yongfa Xiangjie argues that "Wuyi" is only a adverb╶not an adjective. I partly agree with this assessment. My opinion is that "Wuyi" fits the adjective and adverb classification.

How to change the electrostatic chuck, the heat transfer coefficient profiles are provided by configuring the surface density of the mesa structure of the electrostatic chuck dielectric layer. The method for changing the capacity of the electrostatic chuck by a profile control or the initial production of the height of the mesa structure of the electrostatic chuck, an insulating layer is also provided. While the heat transfer coefficient at a given site can be measured using a heat flux probe, capacity at a given site it may be measured using a capacitance probe. The probe is located on the chuck insulating surface, it may comprise a plurality of mesas on a single measurement. Plurality of measurements made over the chuck provides a heat transfer coefficient of the profile or profiles, and the capacity, the density target mesa surface and mesa target height is determined therefrom. It is achieved mechanically, and increase the target density; Respectively, the target density is by adjusting the height of a conventional surface density of the mesa mechanically, the target is accomplished by creating a deeper or lower region of the proposed prior art mesa or around the mesa. This is known for the removal of a controlled material, such as grit blasting or laser machining on the XY table machining techniques can be accomplished using any of it.

ABSTRACT Personal trajectory data are increasingly collected for a variety of academic and recreational pursuits. As access to location data widens and locations are linked to other information repositories, individuals become increasingly vulnerable to identification. The quality and precision of spatially linked attributes are essential to accurate analysis; yet, there is a trade-off between privacy and geographic data resolution. Obfuscation of point data, or masking, is a solution that aims to protect privacy and maximize preservation of spatial pattern. Trajectory data, with multiple locations recorded for an entity over time, is a strong personal identifier. This study explores the balance between privacy and spatial pattern resulting from two methods of obfuscation for personal GPS data: grid masking and random perturbation. These methods are applied to travel survey GPS data in the greater metropolitan regions of Chicago and Atlanta. The rate of pattern correlation between the original and masked data sets declines as the distance thresholds for masking increase. Grid masking at the 250-m threshold preserves route anonymity better than other methods and distance thresholds tested, but preserves spatial pattern least. This study also finds via linear regression that median trip speed and road density are significant predictors of trip anonymity.


In the present study, we evaluate the toxicity of seven insecticides to the predatory wasps Brachygastra lecheguana, Protonectarina sylveirae, Polybia scutellaris and Polybia fastidiosuscula (Hymenoptera: Vespidae), relative to Plutella xylostella (Lepidoptera: Plutellidae). Adults of the predatory wasps and larvae of P. xylostella were exposed to nine concentrations of carbaryl, cartap, deltamethrin, methamidophos, methyl parathion, permethrin and trichlorfon. Selectivity, toxicity, and tolerance ratios were calculated from LC 50 values to determine insecticide toxicity to predatory wasps and P. xylostella as well as insecticide tolerance of the predatory wasps. The predatory wasps showed steeper slopes in concentration-mortality regression lines for insecticides than the P. xylostella. Overall, the insecticides showed no selectivity in favor of predatory wasps, thus the LC 50 were higher for P. xylostella than for predatory wasps. Cartap showed selectivity to the predatory wasps B. lecheguana, and P. sylveirae and trichlorfon was selective to P. sylveirae. The mortality of P. scutellaris estimated by all insecticides tested was higher than 95%. In addition, the mortalities ofB. lecheguana, P. sylveirae, and P. fastidiosuscula by all insecticides tested were higher than 80%, except for cartap, which caused 41, 42 and 71% wasp mortality, respectively. P. fastidiosuscula was the most susceptible wasp to the majority of the insecticides as indicated by lower LC 50 values for the insect relative to the other wasps. Deltamethrin and permethrin were the most potent insecticides against B. lecheguana and P. sylveirae, as were deltamethrin and methyl parathion against P. scutellaris, and carbaryl, deltamethrin and methyl parathion against P. fastidiosuscula.


The deployment of CO2 capture and storage (CCS) and negative emissions technologies (NETs) are crucial to meeting the net-zero emissions target by the year 2050, as emphasised by the Glasgow Climate Pact. Over the years, several energy planning models have been developed to address the temporal aspects of carbon management. However, limited works have incorporated CCS and NETs for bottom-up energy planning at the individual plant scale, which is considered in this work. The novel formulation is implemented in an open-source energy system software that has been developed in this work for optimal decarbonisation planning. The DECarbonation Options Optimisation (DECO2) software considers multiperiod energy planning with a superstructural model and was developed in Python with an integrated user interface in Microsoft Excel. The software application is demonstrated with two scenarios that differ in terms of the availabilities of mitigation technologies. For the more conservative Scenario 1, in which CCS is only available in later years, and other NETs are assumed not to be available, all coal plants were replaced with biomass. Meanwhile, only 38% of natural gas plants are CCS retrofitted. The remaining natural gas plants are replaced with biogas. For the more aggressive Scenario 2, which includes all mitigation technologies, once again, all coal plants undergo fuel substitution. However, close to half of the natural gas plants are CCS retrofitted. The results demonstrated the potential of fuel substitutions for low-carbon alternatives in existing coal and natural gas power plants. Additionally, once NETs are mature and are available for commercial deployment, their deployment is crucial in aiding CO2 removal in minimal investment costs scenarios. However, the results indicate that the deployment of energy-producing NETs (EP-NETs), e.g., biochar and biomass with CCS, are far more beneficial in CO2 removal versus energy-consuming NETs (EC-NETs), e.g., enhanced weathering. The newly developed open-source software demonstrates the importance of determining the optimal deployment of mitigation technologies in meeting climate change targets for each period, as well as driving the achievement of net-zero emissions by mid-century.


An epidemic of aphid-transmitted potato virus Y (PVY) in seed potato grown in the Red River Valley of Minnesota and North Dakota was the reason we began a study to determine which aphid species were found in traps placed near potato fields. Knowledge of which aphid species are present and which of these are known vectors of PVY is needed to develop management strategies that minimize virus spread. The spread of PVY to healthy indicator plants and captures of alate aphids in tile traps were monitored weekly for 3 yr consecutively (1992-1994) throughout the Red River Valley. Thirty-four aphid species were identified from green and yellow tile traps in 1992, 25 in 1993, and 26 in 1994. Yellow tile traps caught significantly more aphids overall than green tile traps and were significantly preferred by Aphis helianthi Monell, Capitophorus elaeagni (del Guercio), and Rhopalosiphummaidis (Fitch). Intervals of greatest aphid capture in green traps were generally between mid-July and mid-August at all sites in all 3 yr. Aphid captures at all sites were 3-25 times greater in 1992 and 1994 than in 1993. PVY infection of indicator plants exposed at the trapping sites also was greater in 1992 (25 plants) and 1994 (18 plants) than in 1993 (2 plants). Eighty-nine percent of PVY spread to indicator plants occurred between 8 July and 19 August. Eight species comprised 89.9% of the aphids collected in green traps during intervals of PVY transmission to indicator plants: Acyrthosiphon pisum (Harris), pea aphid; A. helianthi; C. elaeagni; Lipaphis erysimi (Kaltenbach), turnip aphid; R. maidis , com leaf aphid; R. padi (L.), bird cherry-oat aphid; Schizaphis graminum (Rondani), greenbug; and Sitobion avenae (F.), English grain aphid. Seven of these species were previously known PVY vectors. We found that A. helianthi transmitted PVY with low efficiency under greenhouse conditions. The 8 most common aphid species were associated with crops and weeds common in the Red River Valley. Our data suggest that although the relative importance of individual PVY vectors varies from year to year and location by location, total aphid captures may be the best indicator of the risk of PVY spread.

Population of England MSOAs by quinary age band and sex.The methodology used to produce the mid-2002 and mid-2003 SOA estimates differs to the method used to produce the mid-2002 and mid-2003 local authority estimates, and is subject to further development. In view of this ongoing work the mid-2001, mid-2002 and mid-2003 SOA estimates are being published as 'experimental statistics'


Cellulosomes are multienzymatic complexes whose com- ponents interact in a cooperative way (synergically) to hydrolyze cel- lulose. They are essentially composed of several types of cellulases assembled on a scaffolding subunit. The cellulosomes are organized in polycellulosomal organelles, which form protuberances on the sur- face of cellulolytic bacteria. A combination of genetic, biochemical, crystallographic and microscopic techniques have helped to obtain more insight into the structure of cellulose and of its hydrolysis mechanism. In this work we present an actualized review of the study of these complexes.


Objective: This study looks at the changes in injuries after the implementation of a new rule by the International Boxing Association (AIBA) to remove head guards from its competitions. Design: A cross-sectional observational study performed prospectively. This brief report examines the removal of head guards in 2 different ways. The first was to examine the stoppages due to blows to the head by comparing World Series Boxing (WSB), without head guards, to other AIBA competitions with head guards. Secondly, we examined the last 3 world championships: 2009 and 2011 (with head guards) and 2013 (without head guards). Setting: World Series Boxing and AIBA world championship boxing. Participants: Boxers from WSB and AIBA world championships. Interventions: The information was recorded by ringside medical physicians. Main Outcome Measures: Stoppages per 10 000 rounds; stoppages per 1000 hours. Results: Both studies show that the number of stoppages due to head blows was significantly decreased without head guards. The studies also showed that there was a notable increase in cuts. Conclusions: Removing head guards may reduce the already small risk of acute brain injury in amateur boxing.


The purpose of this paper is to present a new optimised approach for product variance from the purchasing perspective. The research is based on a case study involving a global acting automotive Tier 1 supplier who produces steering systems for cars and commercial vehicles. The case study analysis the product variance of three components. The data were gathered from 116 variants, 13 sub suppliers for three different types of steering system. Time, money, quality and technology can be saved through a greater understanding of such product variances. The results of the case study lead to a generalised method to optimise the existing variance, present cost improvements as well as optimising new key performance indicators to manage product variance out of the purchasing department. © 2017 The Authors.

Management of the feral Horse (Equus caballus) in the Australian Alps bioregion is a difficult and emotive issue, with interested parties working from vastly differing perspectives. Compounding this, information regarding ecology and distribution of horses, and the cost and effectiveness of management strategies is often unknown or uncertain. Resolving these issues requires an objective approach with the flexibility to incorporate different potential scenarios. We used a spatially explicit population model to compare the potential effects of two different management strategies on populations of horses in the Australian Alps bioregion: culling from helicopters versus trapping and mustering. We populated the model using the results of population surveys conducted in 2014, vegetation data and cost estimates. We then provided an estimate of the effect of each strategy on population size across the Alps, and their corresponding costs, compared to no management. To account for uncertainties, we simulated different scenarios for horse population densities, dispersal rates and population growth rates. Management using aerial culling was more effective than mustering in every scenario modelled, and three to six times cheaper. Aerial culling was only slightly more effective within its control region. However, because mustering is necessarily restricted by road access, this translated to a substantial improvement in population control – up to 2000 horses where growth and dispersal rates were high. Our results unequivocally suggest aerial culling as the only strategy that could effectively control horses within the modelled range of scenarios; this result stands in addition to its other potential benefits of lower cost, animal stress and landscape disturbance. A major advantage of this modelling approach is that we can easily update it with new data, test different measures of effectiveness and add new scenarios to adapt to the rapidly changing situation on the ground, both in terms of the ecology and the political climate.


We investigated the role of intrinsic defects in the electronic and optical properties of mercuric iodide using ab initio methods. The calculations were performed using the total energy all electron methodology, considering full atomic relaxation. We computed the band structure, spin, formation and transition energies, and the dielectric function of isolated iodine and mercury vacancies in several charge states. Our results were compared to available experimental data on photoluminescence and photoplasticity in HgI2. We propose a microscopic model which can explain most of the data on those luminescent centers, unifying experimental results which suggested conflicting conclusions.


The paper describes the potential network efficiency gain for network operators by infrastructure and network sharing, which considers both infrastructure and spectrum sharing between wireless cellular network operators. The results and conclusions encourage to consider the inter-operator resources sharing scenarios and techniques as potential solutions for future networks.

There is some evidence, although yet unconfirmed, that Sagittarius A*—the supermassive black hole at the Galactic center—emits its radio waves modulated with a ~100 day period. What is intriguing about this apparent quasi periodicity is that although the amplitude of the modulation increases with decreasing wavelength (from 3.6 to 1.3 cm), the quasi period itself does not seem to depend on the frequency of the radiation. It is difficult to imagine how a binary companion, were that the cause of this modulation, could have escaped detection until now. Instead, it has been suggested that the spin-induced precession of a disk surrounding a slowly rotating black hole could have the right period to account for this behavior. In this paper, we examine how Sgr A*'s light curve could be modulated by this mechanism. We demonstrate that the partial occultation of a nonthermal halo by a compact, radio-opaque disk does indeed produce the observed frequency-dependent amplitude. This appears to be in line with other observational arguments suggesting that Sgr A*'s millimeter/submillimeter spectrum is produced by a ~10 Schwarzschild radius disk, whereas its centimeter waves originate from a nonthermal particle distribution in a halo extending out to over 20 Schwarzschild radii. Interestingly, this model suggests that the observed period corresponds to half the precession period and that a nonaxisymmetric disk could produce a second period roughly twice as long as the first.


We consider Superset, a lesser-known yet interesting variant of the famous card game Set. Here, players look for Supersets instead of Sets, that is, the symmetric difference of two Sets that intersect in exactly one card. In this paper, we pose questions that have been previously posed for Set and provide answers to them; we also show relations between Set and Superset.
For the regular Set deck, which can be identified with F^3_4, we give a proof for the fact that the maximum number of cards that can be on the table without having a Superset is 9. This solves an open question posed by McMahon et al. in 2016. For the deck corresponding to F^3_d, we show that this number is Omega(1.442^d) and O(1.733^d). We also compute probabilities of the presence of a superset in a collection of cards drawn uniformly at random. Finally, we consider the computational complexity of deciding whether a multi-value version of Set or Superset is contained in a given set of cards, and show an FPT-reduction from the problem for Set to that for Superset, implying W[1]-hardness of the problem for Superset.


The traditional hemagglutination techniques frequently use centrifugation and mechanical suspension. The advantage of these processes is the acceleration of the reactions, however they present the inconvenience of making complete automatisation of these tests difficult especially when microplaques are used. Our study demonstrates the force of the ultrasonic radiation created in an atmosphere of suspension and is susceptible to replacing all mechanical movements.


The content of biologically active substances and antioxidant activity in leaves and inflorescences of three species from the tribe Cynareae of the Asteraceae family: Centaurea cyanus,Centaurea macrocephala, Rhaponticum carthamoides, grown under the conditions of the Central Siberian Botanical Garden introduction was studied. It was determined that leaves and inflorescences contain flavonols, catechins, tannins, carotenoids, pectin substances. The highest level of tannins (up to 27.7%) in leaves and flavonols in leaves and inflorescences (up to 4.93 %) was found in plants of R. carthamoides. High content of catechins (up to 140.2 mg%) was found in leaves and inflorescences of C. macrocephala. Carotenoids are mainly accumulated in leaves of R. carthamoides (51.73 mg%) and inflorescences of C. macrocephala (11.86 mg%). The highest content of pectins was noted in leaves and inflorescences of C. cyanus (1.7% and 2.6%), protopectins - in leaves (up to 10.54 %). The highest antioxidant activity (0.72 мг/г) and anti-radical activity (IC50=0.58–0.77 мг/г) were recorded for water-ethanol extracts from leaves and inflorescences of C. macrocephala. Water-ethanol extracts of C. cyanus exhibited low antiradical activity (IC50=4.43–8.13 mg/g).


There will be described systems and methods relating to a database query optimization and query cost estimate. The approach is in the context of searching of balanced and semi balanced tree indexes such. described as B-trees, B + trees and RB trees. The described approach can be used both for simple as well as compound queries, and the approach described may be used for relational queries, that is, when a variable is smaller or larger than a certain value and the database is used to find the record, which satisfies the relation. Moreover, the approach to generalized N-ary tree queries, and expense estimates described can be used.


This study focuses on leadership training in three domains for ministry leaders who serve in multicultural contexts. What preparations are required to work in these multicultural contexts? The writer suggests the importance of leadership training in three domains - cognitive, affective, and behavioral domains. Training for these three domains should be balanced for holistic leadership development. In cognitive domain development, ministry leaders should become equipped with biblical and cultural understanding. The biblical teachings regarding aliens are clear-Christians are to take care of aliens and work with them without discrimination. Leaders also must have a cultural understanding toward different ethnicities and nations, because this knowledge enables them to understand and to work with them effectively. For affective domain development, ministry leaders should develop five hearts-disciplined mind, synthesizing mind, creating mind, ethical mind, and respectful mind. Leaders are to have spirituality training in order to control their heart. Spirituality training can be accomplished when leaders take care of their inner life, renew their personality through meditation on the Word of God, and through theological reflection. Finally, leaders are to train themselves in the behavioral domain for better ministry performance. Various behavioral leadership competences can be acquired through the training process.

9638 Background: Carcinoembryonic antigen (CEA) is widely used as a serum tumor marker. Several systems for the CEA-RT-PCR approach have been reported to date. In this study, we have evaluated quantitative CEA-RT-PCR as a diagnostic tool for detection of isolated tumor cells in the bone marrow of early breast cancer patients prior adjuvant systemic therapy. Methods: We obtained bone marrow aspirates from 70 patients with stage I (37%), II (60%), and III (3%) breast cancer who underwent either immediate complete resection of the tumor or were planned for neoadjuvant therapy with subsequent curative surgery. mRNA was isolated using QIAamp RNA blood mini kit (Qiagen). Subsequently quantitative RT-PCR for the expression of CEA was performed. Results: CEA was detected in samples from 29 (41%) out of 70 patients. With a median follow-up of 22 month we observed 6 recurrences, two in patients with positive bone marrow. At the time of analysis 2 patients died. None of these deaths were tumor related.

Sturm–Liouville differential operators on compact graphs without cycles (i.e. on trees) are studied. We establish properties of the spectral characteristics and investigate two inverse problems of recovering the operator from the so-called Weyl functions and from a system of spectra. For these inverse problems, we prove the uniqueness theorems and obtain a procedure for constructing the solution by the method of spectral mappings.


Objective To observe the changes of Schirmer I test value(SIT),corneal fluorescein and rose Bengal staining,and morphological alterations of corneal epithelium after lacrimal gland extirpation in rabbits.To evaluate the characteristics of the rabbit dry eye model.Method The S1T value,corneal fluorescein and rose Bengal staining before and after lacrimal gland extirpation were graded.The cornea was taken for transmission electron microscopic examination.Result After lacrimal gland extirpation,the S1T was statistically significantly decreased(20.25±5.52 mm/5 min before and 15.88±6.29 mm/5 min after extirpation,P=0.0062).The average grade point of the corneal fluorescein and rose bengal staining(8.22±1.99 and 7.67±0.87,respectively)was significantly higher than that before the model establishment(0.22±0.44 and 0.67±0.5,respectively,P0.0001).The variation of the above mentioned three testing indexes indicated that tear deficient dry eye after the extirpation of lacrimal gland caused punctate erosions and necrosis of the corneal epithelium.Transmission electron microscopic observation revealed liquidation of superficial epithelial cells and break of basement membrane in the cornea after the model establishment.Those changes were characteristic of dry eye.Conclusion After lacrimal gland extirpation,the tear secretion decreases and punctate erosion and necrosis of corneal epithelium occurs.Thus,a rabbit model of dry eye with decresed tear secretion and punctate erosion and necrosis of corneal epithelium can be successfully established by lacrimal gland extirpation.


Abstract We show that if the Hardy–Littewood maximal operator M is bounded on a reflexive variable exponent space L p  ( ⋅ )  ( ℝ d ) {L^{p(\,\cdot\,)}(\mathbb{R}^{d})} , then for every q ∈ ( 1 , ∞ ) {q\in(1,\infty)} , the exponent p  ( ⋅ ) {p(\,\cdot\,)} admits, for all sufficiently small θ > 0 {\theta>0} , the representation 1 p  ( x ) = θ q + 1 - θ r  ( x ) {\frac{1}{p(x)}=\frac{\theta}{q}+\frac{1-\theta}{r(x)}} , x ∈ ℝ d {x\in\mathbb{R}^{d}} , such that the operator M is bounded on the variable Lebesgue space L r  ( ⋅ )  ( ℝ d ) {L^{r(\,\cdot\,)}(\mathbb{R}^{d})} . This result can be applied for transferring properties like compactness of linear operators from standard Lebesgue spaces to variable Lebesgue spaces by using interpolation techniques.


Steam explosion (SE) was used to pretreat rice straw (RS) and Caragana korshinskii Kom. (CKK). Enzymatic hydrolysis of pretreated RS and CKK, and a pure cellulose (bacterial cellulose, BC) were performed and compared. The characteristics and changes of different substrates during pretreatment and enzymatic hydrolysis were observed. After SE pretreatment, the hemicellulose content of RS and CKK was decreased from 21.7% to 4.9% and 17.9% to 6.2%, respectively. The cellulose percent of RS and CKK was increased to 45.1% and 38.4%, and the enzymatic hydrolysis conversion of cellulose was increased 1.1 times and 0.9 times, respectively. Although the composition and enzymatic yield of different substrates varied, their enzymatic hydrolysis rates showed a similar declining trend during enzymatic hydrolysis. The adsorption capacities of substrates on the enzyme were increased by pretreatment. The enzymatic hydrolysis efficiency was closely related to the enzyme adsorption capacities of substrates at the initial stage (1 h). The BC and SE pretreated RS first adsorbed and subsequently desorbed the enzyme, while the untreated RS and CKK had weak adsorption capacity and formed irreversible adsorption with the enzyme. The changes in crystallinity after enzymatic hydrolysis suggested that there was no direct correlation between the crystallinity and digestibility of cellulose.


In 1909 Santschi described an ant, said to have been taken in Tucson, Arizona, as Tetramorium silvestrii. Nothing in Santschi's description indicates that silvestrii is actually a member of the genus Leptothoracx, hence the writer believes that when Emery transferred silvestrii to Leptothorax in 1922, he must have done so on the basis of material sent him by Santschi. But since Emery did not explain how he was able to make this transfer, the generic reallocation was factually unsupported. No additional material of silvestrii was taken for more than a quarter of a century after Emery's shift, and during that period three courses were open to myrmecologists in the case of silvestrii. It could be treated as a Tetramorium on the basis of Santschi's description; it could be considered as a Leptothorax on the basis of Emery's transfer; or it could be regarded as a species of doubtful generic affinity. In recent years this unsatisfactory situation has been eliminated by the discovery of additional specimens of silvestrii. These specimens prove that Emery was correct in treating silvestrii as a member of the genus Leptothorax. Indeed, about the only feature which might suggest a relationship to Tetramorium is the rectangular node of the petiole. The clypeus is typically that of Leptothorax, and it is hard to understand how Santschi could have supposed that silvestrii belongs to Tetratmorium. As far as the writer has been able to ascertain, the first myrmecologist to discover additional specimens of silvestrii was L. F. Byars. About 1949 Byars took a single nest of this insect at Ruby, Arizona, a mining camp a few miles north of the border in Santa Cruz County. Specimens from this nest were sent to M. R. Smith for identification. Smith correctly considered that these specimens were the lost silvestrii, but to

Robert Bly was not only the leader of Deep Imagism in Surrealistic Poetry,but also a nature poet who combined both mystic temperament and ecological awareness. He learned from Carl Jung the unconscious theory,and presented the eagerness in showing respect and even conviction to nature through treating nature wholly,double-facedly,and sensually,in his early deep image poetry Silence in the Snowy Fields,which shows an admirable ecological awareness. This has won him the popularity in the present century.

Comparative research of agenda setting by high courts in other countries that replicates American research on the certiorari process is rare. This is the first study of the leave to appeal process in the Supreme Court of Canada. It also is the first multivariate model that operationalizes the jurisprudential indicia Perry identified as important when the U.S. Supreme Court "decides to decide." This study finds that endogenous institutional norms in Canada produce a decentralized process in which legal cues or signals are emphasized but in diverse and varied ways. Institutional differences across high courts therefore affect the generalizability of American findings.


Synthesis of n-butyl acetate catalyzed by 1-butanol and acetic acid on metal-loaded cation exchange resin was studied.The influence factors were studied,the optimum process conditions were determined,included a reacting time 60 minutes,metal-loaded cation exchange resin was 40% of the amount of acetic acid,and mole ratio n(1-butanol)/n(acetic acid) =1.1:1.On these conditions,the yield of n-butyl acetate was above 97 %.

The combined benefits of mesoporosity and in situ grown conductive amorphous carbon on lithium storage capacity of anatase TiO 2 are discussed here. Micron-sized anatase TiO 2 spheres with equal amount of carbon but different degree of mesoporosity and normal mesoporous TiO 2 are synthesized by solvothermal and sol-gel methods respectively. While the specific surface areas were 80, 35 and 85 m 2 g ―1 respectively for mesoporous carbon-TiO 2 sphere, carbon-TiO 2 sphere and mesoporous TiO 2 , the primary size of the grains constituting the micrometer sized spheres was ∼11 nm. The electrochemical lithium stored by all synthesized TiO 2 materials show strong dependency on mesoporosity and carbon. Mesoporous carbon-TiO 2 sphere exhibited a first discharge cycle capacity of 334 mAh g ―1 at current rate of 66 mAg ―1 , whereas carbon-TiO 2 sphere and mesoporous TiO 2 stored 120 and 270 mAh g ―1 respectively. Demonstration of high lithium storage capacity and good cyclability in mesoporous carbon-TiO 2 ' sphere is attributed to the synergy of mesoporosity and in situ grown carbon in the formation of an effective percolation network for the conducting species (Li + /e ― ) around TiO 2 nanoparticles.

The structure of consonant trigrams of high formal similarity was manipulated such that selection from position 1, 2, or 3 for different experimental groups would differentiate these stimuli both on the first list and on the transfer list, where the structure was the same but the stimuli themselves were new. First-list learning was a function of position (1 > 3 > 2), but transfer-list learning was not, despite the changed stimuli. The control groups, who had no opportunity to learn a selection rule on the first list, did show differences in transfer-list learning as a function of position. The results are interpreted as indicating the acquisition of selection rules, and the theoretical implications for stimulus coding are discussed.


Abstract.
 The Commission has conserved the specific name of the widespread West Palaearctic saprophagous fly Pteremis fenestralis (Fallén, 1820) (sphaeroceridae) in its current usage. The exant syntypes have been set aside and a male specimen from Sweden, which corresponds to the current usage of the name, has been designated as neotype.


The problems with passwords are well-known: secure passwords are difficult to remember, users have too many passwords, and users have difficulty matching their passwords to accounts. Password managers and cued graphical passwords are two password solutions that address the issues of memorability and keeping track of of passwords. We have developed Versipass, a password manager that incorporates key elements of password managers and cued graphical passwords to avoid existing problems of password memorability and associating passwords with accounts. Instead of remembering passwords, Versipass remembers image cues for graphical passwords. These cues help users to better remember their passwords and to more easily link passwords with accounts. Versipass also facilitates safe password reuse by allowing users to use the same image cue for multiple accounts.

prove the existence of solutions to the following Kirchhoff
nonlocal fractional equation:

& u = 0, \quad \textrm{in}\;\; \mathbb{R}^n \setminus \Omega,
\end{eqnarray}
where $(- \Delta)^s$ is the fractional Laplace operator, $s \in

some suitable conditions.

Epicardial coronary artery disease has been highly noticed in the traditional clinical examination, while myocardial microcirculation function has been neglected for a long time, which plays a nonnegligible role in quite a few patients' clinical manifestations and prognosis. Non-invasive quantitative PET myocardial perfusion imaging has become a unique and gold standard of evaluating myocardial microcirculation function. Its clinical applications in diagnosis, risk stratification, prognosis evaluation, efficacy evaluation and treatment guidance of cardiovascular diseases are given, together with its development status in China.


Background: Uptake of various cell-penetrating peptides (CPPs) can be toxic to cells. Results: Amphipathic CPPs disorder the plasma membrane inducing the influx of calcium ions that in turn can activate recovery mechanisms. Conclusion: Influx of calcium ions and subsequent toxicity induced by the uptake of CPPs can be averted efficiently. Significance: Membrane-active CPPs can be exploited as efficient transport vectors. Cell-penetrating peptides (CPPs) promote the uptake of different cargo molecules, e.g. therapeutic compounds, making the harnessing of CPPs a promising strategy for drug design and delivery. However, the internalization mechanisms of CPPs are still under discussion, and it is not clear how cells compensate the disturbances induced by peptides in the plasma membrane. In this study, we demonstrate that the uptake of various CPPs enhances the intracellular Ca2+ levels in Jurkat and HeLa cells. The elevated Ca2+ concentration in turn triggers plasma membrane blebbing, lysosomal exocytosis, and membrane repair response. Our results indicate that CPPs split into two major classes: (i) amphipathic CPPs that modulate the plasma membrane integrity inducing influx of Ca2+ and activating downstream responses starting from low concentrations; (ii) non-amphipathic CPPs that do not evoke changes at relevant concentrations. Triggering of the membrane repair response may help cells to replace distorted plasma membrane regions and cells can recover from the influx of Ca2+ if its level is not drastically elevated.


This report deals with the problem of contaminant transport in the saturated and unsaturated domains of phreatic aquifer. Numerical solutions by the finite-element method are obtained for fertilizer dissolution and seawater intrusion. The main results are as follows : 1) In fertilizer dissolution from the center of the aquifer surface, since the dispersion coefficient becomes smaller, the pattern of the steady state concentration distribution becomes more eccentric towards the outlet of the aquifer. When the dispersion coefficient increases or the precipitation intensity decreases, the concentration distribution changes more slowly to the steady state distribution. 2) With seawater intrusion, since the dispersion coefficient becomes smaller, the pattern of the steady state concentration distribution in the saturated domain chages from strong to moderate mixing, and a circulating current develops near the outlet of the aquifer.


Based on the analysis and comparison among existing ray tracing methods, a new modified linear traveltime interpolation (LTI) method is proposed in this paper. The developed method remains the virtue of LTI but is more precise than the original LTI. By analyzing the forward modeling and inversion process of the LTI algorithm, the backward ray tracing LTI algorithm is adopted. It can keep ray tracing from local minimum by computing the velocity of grid nodes in advance. Compared with original LTI, the new algorithm is able to compute the shortest ray path. Tomography based on the improved LTI traveltime data can reflect the size and property of the defect with high resolving power. The developed ray tracing technique for Lamb wave quantitative nondestructive evaluation is of great significance in both theory and practice.


In heterogeneous multi-cell networks (HetNets), inter-and intra-cell interference are critical issues impairing the performance. In this paper, the frequency-hopping (FH) technique based on an attractive FH sequence (FHS) set with two-level Hamming correlations is exploited in such networks. Motivating from the idea of no-and low-hit-zone FHS sets, a construction algorithm of the new FHS set is proposed by utilizing the interleaving technique. Then, the performance metric of such FHS set in terms of Hamming correlation properties are derived, which are verified by an example. Compared with classic FHS sets (patterns), the proposed FHS set offers a zero Hamming cross-correlation for intra-cell users, and a low Hamming cross-correlation for inter-cell users (i.e., multi-level quality-of-services). The intra-and inter-interference in multi-cell HetNets can be significantly reduced by the proposed sequence-based FH technique.

One of the goals of the MSc Energy for Smart Cities has evolved to the creation of start-ups after educating innovative engineers in the 4 European Universities that participate. The results of the Challenge Based Education applied to 1st year Master students during the Innovation Journey (IJ) using this methodology has increased the motivation of a part of the students for being entrepreneurs and also to create their own startup. The first edition of the Entrepreneurship Journey (EJ) for 2nd year students started in the course 2016-17 with 10 students and 3 start-up initiatives, and the success story of the FlexiDao start-up created. In this paper, the main characteristics of the Challenge Based Education in the IJ that fosters the creation of start-ups in the EJ are detailed for each of the key stakeholders involved: students, challenge owners, teachers and start-up ecosystem. Two of those elements, students and ecosystems, are further analysed in this paper using different research methodologies. The student perspective has been analysed via a survey to the participants in the last three editions with a self-evaluation of their progression using the EntreComp Framework. The ecosystem perspective has been analysed with a literature review and experts' opinions. Main results provide insights on how entrepreneurship is a natural consequence of Challenge Based learning.


Purpose : To evaluate the clinical use of the menopause-specific quality of life questionnaire(MENQOL) for scoring menopausal symptoms by comparison with the conventional Kupperman's index. Methods : A population sample of 66 women was randomly selected from the female patients(aged 45-55) who had visited two oriental medical clinic in Seoul or Woo-Shin-Hwang oriental hospital from 1st April to 15th May in 2006. They completed both the MENQOL and the Kupperman's index and were asked a few additional questions. Results : 1. A degree of the Climacteric symptoms were not significantly related to either an education level or an income level. 2. A comparison of the MENQOL with the Kupperman's index produced a high positive correlation. 3. 41 of subjects (62.1%) answered that the MENQOL was more efficient for explaining their symptoms than the Kupperman's index. 49 (74.2%) of subject thought that both questionnaires are equally not difficult to fill out and 44(66.7%) of subject found no difficult questions to answer in any of questionnaires. Conclusion : The MENQOL is a valuable modern tool for the assessment of climacteric symptoms in place of the Kupperman's index. The MENQOL was excellent in applicability. The MENQOL could serve as an adequate diagnostic instrument for climacteric symptoms.


In an effort to understand the reasons for system plugging problems in the SRS 2F evaporator, supernatant samples were retrieved from the evaporator feed tank (Tank 26F) and solids were collected from the evaporator eductor feed pump for characterization. The variable depth supernatant samples were retrieved from Tank 26F in early December of 2010 and samples were provided to SRNL and the F/H Area laboratories for analysis. Inspection and analysis of the samples at SRNL was initiated in early March of 2011. During the interim period, samples were frequently exposed to temperatures as low as 12 C with daily temperature fluctuations as high as 10 C. The temperature at the time of sample collection from the waste tank was 51 C. Upon opening the supernatant bottles at SRNL, many brown solids were observed in both of the Tank 26F supernatant samples. In contrast, no solids were observed in the supernatant samples sent to the F/H Area laboratories, where the analysis was completed within a few days after receipt. Based on these results, it is believed that the original Tank 26F supernatant samples did not contain solids, but solids formed during the interim period while samples were stored at ambient temperaturemore » in the SRNL shielded cells without direct climate control. Many insoluble solids (>11 wt. % for one sample) were observed in the Tank 26F supernatant samples after three months of storage at SRNL which would not dissolve in the supernatant solution in two days at 51 C. Characterization of these solids along with the eductor pump solids revealed the presence of sodium oxalate and clarkeite (uranyl oxyhydroxide) as major crystalline phases. Sodium nitrate was the dominant crystalline phase present in the unwashed Eductor Pump solids. Crystalline sodium nitrate may have formed during the drying of the solids after filtration or may have been formed in the Tank 26F supernatant during storage since the solution was found to be very concentrated (9-12 M Na{sup +}). Concentrated mineral acids and elevated temperature were required to dissolve all of these solids. The refractory nature of some of the solids is consistent with the presence of metal oxides such as aluminosilicates (observed as a minor phase by XRD). Characterization of the water wash solutions and the digested solids confirmed the presence of oxalate salts in both solid samples. Sulfate enrichment was also observed in the Tank 26F solids wash solution, indicating the presence of sulfate precipitates such as burkeite. OLI modeling of the Tank 26F filtered supernatant composition revealed that sodium oxalate has a very low solubility in this solution. The model predicts that the sodium oxalate solubility in the Tank 26F supernatant is only 0.0011 M at 50 C. The results indicate that the highly concentrated nature of the evaporator feed solution and the addition of oxalate anion to the waste stream each contribute to the formation of insoluble solids in the 2F evaporator system.« less

The self-writings – I call them bio-writings – reveal about the performative constitution of gender, in that the author, when building himself biographically, constructs himself as a gendered subject in negotiation with the dictates of biopolitics. From this perspective, this work investigates, through bio-written records by William Butler Yeats, how the writer's dilemmatic tension between heteronormativity and homoculture marked his personal and literary formation. Despite his obsession with identity stability, Yeats deconstructs the very sense of identity and, despite his efforts to ratify his heterosexuality, he ultimately disorient sexual orientation as he dismantles supposedly stable binary oppositions between masculinity and femininity, hetero and homosexuality by transiting between poles that culture assumes as ontologically opposed.


The invention relates to a self-organizing traffic signal coordination control method. Two adjacent signal control intersections and a section of a highway or railway which is contained by the two adjacent signal control intersections are defined as a basic coordination unit. The two intersections in the basic coordination unit are an upper stream and a lower stream. Network optimization is resolved on interactive optimization which is superposed mutually and is arranged between the basic coordination units. Optimization of whole rode network is finished through intercoupling of the basic coordination units. Prediction models and interactive models between the traffic signal control intersections are built. Personal benefits and the lower steam intersection benefits are considered between the intersections, the problems that subarea are relatively fixed, methods are different to switch, and reaction to traffic questions is slow based on coordination control methods of a common cycle in a traditional mode are solved. Self-organizing coordination of the whole road network is achieved. Compulsive common cycles and phase difference are not needed and reaction is faster.


The notion of interpoint-distance-based graphs has in the past, guided the extension of distributional order-measures to multivariate observations. The concept of minimal spanning tree (MST) was introduced as the key pattern for generalizing the univariate two-sample problem to multivariate observations. Here, the multivariate Wald-Wolfowitz test is further quantified using the enhanced representations of orthogonal MSTs. Their advantages are investigated by comparing the similarity between color distributions in the feature space, using a standard feature extraction technique borrowed computer vision. To demonstrate the performance of the proposed scheme, the application on a diverse collection of images has been systematically studied in a query-by-example visual information retrieval task. Experimental results show that a powerful measure of similarity can emerge from the statistical comparison of their efficiently drawn pattern representations


Plant macrofossils consist of reproductive and vegetative plant parts visible to the unaided eye. Lakes and peatlands are the most common repositories for the preservation of Quaternary plant macrofossils; however, natural tar seeps, calcareous nodules, spring deposits, packrat middens, and fossil dung are important sources of plant remains also. In Canada, the first plant macrofossils were collected in the mid-1800s, with a brief period of activity around 1900 before the beginning of modern Quaternary plant macrofossil analyses around 1960. Taphonomic studies indicate that plant macrofossils can be transported, sorted and redeposited long distances, which complicates paleoecological reconstructions. Plant macrofossils are valuable in geological studies of environmental history and climatic change; however, the use of plant macrofossils for biostratigraphic correlation must await further research. Four broad phytogeographic patterns are recognizable on the basis of Quaternary plant macrofossil records in Canada, and plant macrofossils can be used to trace the evolutionary origins of the modern flora.


72Background: Prostate cancer patients and providers confront uncertainty as they consider adjuvant or salvage radiation therapy (ART, SRT) after radical prostatectomy (RP). We prospectively evaluated the impact of the Decipher RP test, which predicts metastasis risk after RP, on decision-making for postoperative radiation therapy. Methods: Between October 2016 and May 2017, 1,319 patients treated with RP and considering ART or SRT were enrolled into a Medicare Certification and Training Registry (CTR). Providers submitted a management recommendation based on initial clinical and pathology findings prior to obtaining the Decipher RP test and again upon receiving test results. Only Medicare patients that met the Local Coverage Determination inclusion criteria (i.e., non-organ confined prostate cancer or positive margins or rising PSA) and whose provider was certified in the CTR registry were included in the analysis. Results: Based on clinical variables alone, treatment was recommended for 26% of adjuvant ...


The pathogenesis of spontaneous cervical artery dissection remains unknown. Infection-mediated damage of the arterial wall may be an important triggering mechanism. We describe a 21 year-old man with respiratory infection (bronchial pneumonia) which was diagnosed and treated with antibiotic few days prior to the right internal carotid artery dissection. The patient presented ischemic retinal and cerebral strokes. Based on literature review, we discuss the possibility of a causal link between infection and arterial dissection.

The formation of clusters in glow discharge plasma processing is of great concern with respect to the production yield. Their appearance, trapping and transport in silane plasmas have been the subject of several publications, but little is known about the mechanism of their formation and growth and how to avoid them in intense discharges used for high rate deposition of amorphous silicon. We present mass spectrometric and light scattering data and theoretical modelling which show that the formation of clusters in a clean silane discharge (total impurity ≈ 10 ppm) is due to a sequential growth of higher silanes Si n H 2n+2 with a strong, catastrophic-like onset starting from pentasilane. A selfconsistent mechanistic model will be presented together with a discussion of alternative ionic mechanisms. Several possibilities of how to avoid the cluster formation at high deposition rates of a-Si will be discussed and documented.


The SPR of the AuNPs, synthesized by the reduction of gold ion with citrate and modified with L-cysteine was used as a novel analytical method for the detection and determination of drugs and species based on aggregation of Au-nanoparticles. However, multivariate calibration modeling
 of the SPR absorbance data by chemometrics method resulted in more accurate results out-comes so that the relative prediction errors were almost lower than 5%. In comparison with the available analytical methods for highly selective and sensitive ternary determination of tramadol, methadone
 and buprenorphine the proposed method is in need of lower amounts of reagents. Through increasing the concentration of the Opiate and Fluent material, a visible color change of AuNPs from wine red to blue was observed so the obvious color change was easily noticeable by naked eyes. However,
 multivariate calibration modelling and 3-d way methods that used for the SPR absorbance data by PARAFAC resulted in more accurate outcomes so that the software, as well as the chemometrics and the solvent kit, with great assurance our kit is unique. PARAFAC is a multi-way method originating
 from psychometrics. Due to various reasons such as high computational power, awareness of the method and its possibilities, the increased complexity complication of the data dealt with in science and industry, is gaining more attention in chemometrics and associated areas.

The purpose of this study is to understand the experiences of international students engaged in partnership programs between their high school and a destination college.  Specifically, this study focuses on the experiences and perceptions of a group of Brazilian international students who graduated from a dual diploma high school program prior to arriving at a four-year research university in the United States to complete their postsecondary education. The study is guided by a conceptual model based in the literature around challenges of international students, Tinto's (1975) academic and social integration theory, and the four primary types of social interactions (Rose-Redwood & Rose-Redwood, 2013).  We utilize a case study method centered on six interviews which investigated students' college experiences during their social and academic integration processes.  The findings provide insight into how participation in the dual diploma high school program benefited international students in their college integration.


Decision tree boosting is considered as an important and widely recognized method in image classification, despite dominance of the deep learning based approaches in this area. Provided with good image features, it can produce a powerful model with unique properties, such as strong predictive power, scalability, interpretability, etc. In this paper, we propose a novel tree boosting framework which capitalizes on the idea of using shallow, sparse and yet powerful oblique decision trees (trained with recently proposed Tree Alternating optimization algorithm) as the base learners. We empirically show that the resulting model achieves better or comparable performance (both in terms of accuracy and model size) against established boosting algorithms such as gradient boosting or AdaBoost in number of benchmarks. Further, we show that such trees can directly and efficiently handle multiclass problems without using one-vs-all strategy employed by most of the practical boosting implementations.


Electronic structure and stability of the VOx species forming on the anatase-TiO2(001)-(4 × 1) reconstructed surface at redox cycle V5+−O−V5+ ⇄ V4+−O−V4 have been investigated on the basis of periodic density functional theory calculations. It is shown that oxidizing of the key intermediate of Mars−van Krevelen mechanism [O−V4+−O−V4+] by the gas phase dioxygen leads to the substantial structure relaxation of the surface VOx species within a monolayer. As a result, the binding energy of the vanadyl bond V═O decreased and the stable peroxide complex V(O−O) can be formed on the fully oxidized VOx/TiO2 surfaces. This complex manifests itself as a peak near Fermi level (−0.23 eV) in the total density of states (DOS) and O-projected density of states (PDOS).

The observer design for non-discretized Navier-Stokes partial differential equations has so far been an open problem. We present a nonlinear PDE observer that estimates the velocity and pressure fields for an infinite channel flow. Also know as the Poisseuille flow, this problem is frequently cited as a paradigm for transition to turbulence, and is a benchmark for flow control and turbulence estimation. Our observer consists of a copy of the nonlinear Navier-Stokes equations, combined with linear injection of output estimation error, with observer gains designed in closed form using backstepping. Pressure and skin friction at one of the walls are the only quantities needed for measurement. For a fully developed channel flow (whether laminar or turbulent), with a Reynolds number possibly above the critical value, but not too far above it, the observer is guaranteed to be convergent to the actual velocity and pressure field, provided its initial estimates are not too far from the actual initial profile. An output feedback result for the linearized infinite channel flow is also presented, combining the observer in this paper with a controller presented in a companion CDC'05 paper. Both results are presented for the 2D case for clarity of exposition, however an extension to 3D is straightforward.


A number of new poly[(2-alkyl)quinazolones] and their arylenevinylene derivatives in pentafluorophenol were prepared. It was shown that the conformationally controlled substitution of methyl groups in poly[(2-methyl)quinazolones] can proceed to yield both trans and cis heteroarylenevinylenes. A mechanism was advanced to describe gelation occurring during the synthesis and polymer-analogous transformations of poly[(2-alkyl)quinazolones]. Based on the synthesized poly(quinazolones) with side arylenevinylene substituents, films exhibiting a brightly yellow-orange fluorescence were prepared.

Immune cell therapy, including engineered T cells, engineered NK cells, and treatments to enhance native T cell response, is a rapidly advancing field of research with great promise to treat multiple diseases. However, multiple challenges, from isolating the correct cell type, determining its mode of action, manufacturing and establishing appropriate quality control criteria, must be overcome to reach its potential. In recent years, cellular energy metabolism has emerged as an important consideration for efficacy and persistence when developing cell therapies.
 Here we evaluate a set of bioluminescent cell-based assays for measuring rate of metabolite uptake, monitoring activity for key metabolic pathways and determining changes in intracellular metabolite levels during T cell transition from naïve to activated to memory phenotypes. Metabolite levels measured include ATP, glucose uptake, malate, branched chain amino acids, and glycogen levels. Depending on the activation state of the cells, the cells respond differently to glycolysis and oxidative phosphorylation inhibitors, as demonstrated by changes to metabolite levels. Energy storage as measured by intracellular glycogen levels also differs depending on the T cell phenotype (naïve, activated, or memory).
 Understanding the processes governing dynamic metabolic changes during cell modification and expansion is required for next-generation cell therapy development. The developed bioluminescent cell-based assays provide the sensitivity, throughput and robustness required for rapid evaluation of such changes.
