Objective To explore the effect of different diets on the vagus nerve reflex in patients with nerve intervention. Methods Clinical data of 120 patients undergoing cerebrovascular intervention during October 2012 and September 2013 was retrospectively analyzed,and the patients were divided into control group( n = 61) and observation group( n = 59). The control group underwent fasting preoperative 12 h,interdicting drink preoperative 4h and drinking water postoperative 1h; the observation group did not undergo preoperative fasting and interdicting drink,and for patients,who were not the first operation of clinicians,should eat 50% semi-liquid diet in preoperative 2 h,Incidence rates of intraoperative and postoperative vagus nerve reflex in the two groups were observed. Results Thirteen patients in control group had vagus nerve reflex in different degrees,while only 2 patients in observation group had low blood pressure, and the differences in the two groups were statistically significant( P 0. 05). Conclusion Patients undergoing nerve intervention do not need preoperative fasting and interdicting drink,and conventional diet nursing care can reduce the incidence rate of perioperative vagus nerve reflex and improve the surgical success rate.

This paper reports the results of an investigation of Dovekies (Alle alle L.) breeding near Cape Atholl and Siorapaluk in the Thule District, Northwest Greenland during July and August 1978. Mean values for body measurements of breeding birds were: total length = 218.2 mm (n = 265), wing length = 122.9 mm (n - 266), tail length - 40.8 mm (n = 266) and body weight = 150.5 g (n = 209). Most measurements between the sexes were not significantly different, but mean body weight of males (153.8 g) was significantly greater than that of females (147.2 g). Body weight was highly correlated with wing length and total length in males, but not in females. Food delivered to nestlings consisted primarily of copepods ( Calanus hyperboreas and C. glacialis ) and amphipods (Parathemisto libellula and Apherusa glacialis). Size of chick meals delivered by male and female parents did not differ significantly and average meal weight was 3.48 g (sd = 1.24, n = 204) with mean weight of meals increasing through the chick-rearing period. General information is presented on measurements of subadults, timing of breeding, feeding areas, population size and colony attendance, and predation and disturbance. The distribution of Dovekie colonies in the Thule District is reviewed and compared with earlier information. Key words: Dovekie, morphometrics, chick diet, seabirds, NW Greenland


Magnetic nanowires (MNWs) rank among the most promising multifunctional magnetic nanomaterials for nanobarcoding applications, especially biolabeling, owing to their nontoxicity and remote excitation using a single magnetic source. Until recently, the first-order reversal curve (FORC) technique has been broadly used to study the MNWs for biolabeling applications. However, since FORC measurements require many data points, this technique is very slow which makes it inapplicable for clinical use. For this reason, we recently developed a fast new framework, named the projection method, to measure the irreversible switching field (ISF) distributions of MNWs as the magnetic signature for the demultiplexing of magnetic biopolymers. Here, we illustrate the ISF distributions of several MNWs types in terms of their coercivity and interaction fields, which are characterized using both FORC and projection methods. Then, we explain how to tailor the ISF distributions to generate distinct signature to reliably and quantitatively demultiplex the magnetically enriched biopolymers.


The Planck satellite detectors are calibrated in the 2015 release using the "orbital dipole", which is the time-dependent dipole generated by the Doppler effect due to the motion of the satellite around the Sun. Such an effect has also relativistic time-dependent corrections of relative magnitude 10−3, due to coupling with the "solar dipole" (the motion of the Sun compared to the CMB rest frame), which are included in the data calibration by the Planck collaboration. We point out that such corrections are subject to a frequency-dependent multiplicative factor. This factor differs from unity especially at the highest frequencies, relevant for the HFI instrument. Since currently Planck calibration errors are dominated by systematics, to the point that polarization data is currently unreliable at large scales, such a correction can in principle be highly relevant for future data releases.


Level crossing (LC) accidents are a significant safety challenge worldwide and for that reason they have been subject of numerous research activities. Joint conclusion is that human behaviour is the main cause of accidents. This study examines how and to which extent certain influential parameters cause accident mechanisms on level crossings. To gain the necessary data we used an on-line survey questionnaire that was sent internationally to key experts in the field of road and railway safety. A total of 185 experts were asked to rank how much certain parameters influence level crossings accident mechanisms and what are the best countermeasures for diminishing accidents at level crossings. To our knowledge, this is the first time that an international survey among key experts was used to gain necessary data about influential parameters regarding level crossings safety. The results of this study could be used by road and railway traffic engineers and policy makers for further enhancement of LC's safety.


Macedonia, as a country located in the central part of the Balkans – a place where identity and language issues and conflicts are very common, with its specific internal ethnic composed population, has developed a unique model of a language policy. Starting with the definition of the concept of language policy, this short paper aims to inform about the model of the language policy in Macedonia and its characteristics and at the same time to expose its impacts thus far. In briefly informing briefly about the languages and linguistic groups of Macedonia, the paper starts with a historical overview of development of the language policies in Macedonia from the mid 19 century, through the socialist period, and the process of independence until the constitutional changes according to the Ohrid Framework Agreement of 2001. In its central part, the paper comprehensively outlines and shows the characteristics of the current language policy of Macedonia developed and designed according to the amendments of the Ohrid Framework Agreement. The model of language policy is described on a legal, institutional and practical level, namely by examples and data about the usage of the minority languages on certain levels and areas such as central government, local-self government, education system and public sphere of life as well as the supportive policies for the Macedonian language. In describing the situation, the paper concludes with an opinion about the impact and consequences of the model of the language policy of Macedonia.


Some of the important critical parameters for assessing the water quality like pH (Hydrogen ion concentration), DO (Dissolved Oxygen), BOD (Biological Oxygen Demand), etc., were monitored at different locations in some major Indian rivers. The results obtained from the study reveals that the critical parameters had increasing values in some monitoring locations, decreasing values, and no variation in values at some other places. It is recommended to have a pH value above 7, higher values of DO, lower values of BOD&FCC (Faecal Coliform Content) for improved water quality. Overall, the water quality improved in most Indian rivers. There was no discharge of industrial wastes, hotels/restaurants wastes, immersing of idols during religious festivals, etc., to the rivers during the COVID-19 lockdown. Therefore, enforcement of strict regulations by the Government of India for disposal of wastes produced from industrial&domestic activities can significantly reduce the water pollution levels in the Indian rivers.

This report describes deciduous tooth extraction in a 10-year-old girl with congenital afibrinogenemia. The patient was referred to our clinic with complains of a toothache and tooth mobility. Several teeth were extracted after injection of 1.0g of a fibrinogen (Fbg) preparation (Fibrinogen HT-Green Cross). First, we extracted deciduous teeth (CD) without postoperative bleeding when the level of Fbg was 46mg/dl. On the next day, we attempted deciduous teeth extraction (EDC) when the level of Fbg was 41mg/dl. Later, however, bleeding occurred at the extraction site. We stopped the bleeding by injecting Fbg preparations. After discharge, swelling of the lower face was caused by local anesthesia. However, the bleeding could be controlled by injecting the same volume of the Fbg preparation.It was suggested that the level of Fbg in patients with congenital afibrinogenemia who undergo dental treatment should be over 50mg/dl even when infiltration anesthesia is used. Furthermore, the level of Fbg should be carefully monitored.

CASE REPORT A 49-year-old right handed man presented to the movement disorders clinic for assessment of his right sided tremor. He had a five month history of rest tremor in his right hand, micrographia and intermittent rest tremor in his right leg. He did not have any involvement of his left side. His gait was unsteady but he was not dragging his feet. He had a one month history of progressive right sided facial droop. He denied any focal weakness in his arms or legs, and no dysphagia and no changes in his sensation. His past medical history included strabismus with decreased vision in his left eye since birth. Dexamethasone, phenytoin and ranitidine were started after his imaging findings. On examination, he had mild dysarthria and a slight dysconjugate gaze, likely long standing, and otherwise full extraocular movements. He had a right facial droop sparing the frontalis muscle. He had rigidity and rest tremor of his right arm, and an intermittent rest tremor in his right leg. He had a postural tremor in his right arm and slight kinetic tremor in both arms. He had bradykinesia in his right hand and mild hesitancy in his foot taps on the right. His writing was tremulous and micrographic. His strength, reflexes and sensory exam were normal with flexor plantar responses. His gait was unsteady but not shuffling, and he had a mildly stooped posture. Prior to being seen in clinic, he had a magnetic resonance image of the brain showing a 5 cm enhancing mass from the left sphenoid wing extending into the left temporal region where it compressed the midbrain (Figure 1). There was midline shift to the right, prominent draining veins in the left frontal regions and enlargement of the left middle meningeal artery. Initially these findings were suggestive of a meningioma. He was seen by neurosurgery and due to the vascularity of this lesion, he underwent pre-operative embolization of the left middle meningeal artery. He had a craniotomy for resection of the lesion. See pre-operative video on-line at www.cjns.org. Histological examination revealed a vascular, highly cellular tumour (Figure 2). The cells had elongated nuclei and were disposed randomly and in fascicular and storiform patterns. The tumour had branching, dilated, thin-walled vascular profiles with a "staghorn" appearance. The tumour cells showed cytoplasmic staining for vimentin and CD34. They were negative for

Following the end of the Gulf War in 1991, two major insurgencies erupted within Iraq. The Kurdish uprising received considerable attention (and support) within popular, academic and policy-making channels. The uprising among the Shia in the south, however, garnered less attention and certainly much less support. The outcomes of each movement also varied considerably; although not fully successful, the Kurdish movement did succeed in carving out some degree of autonomy for its area. On the other hand, the uprising in the South was crushed. This article is intended to describe the events in the Shia insurgency, the antecedents of the movement and prospects for the future.

Abstract A new flex testing machine has been developed which yields accurate information on cut growth of vulcanizates. Its unique features are accurate temperature control of the test chamber (25°–200° ± 1° C), adjustable work input upon the test specimen by varying both the frequency of flexing (100–600 ± 1 rpm) and flex angle, and accomodation of a large number of test specimens (90–120). Furthermore, provision is made to test with a specific testing atmosphere, either oxidative or inert, depending on the required severity of conditions. Advantages of the test machine are: a) simple operation, once the test conditions are established: b) rapidity of testing, since a large number of specimens can be tested at the same time; and c) excellent reproducibility in preparing test specimens, varying and maintaining test conditions, and measuring cut growth. The maximum standard error for the test is about 12%. A further advantage is that compounds of varying degrees of hardness, for example, tire treads, shoe ...

n-Butanol was recovered from waste pharmaceutical liquor by salting–out extraction process.The effect of mass ratio of potassium carbonate solution to waste pharmaceutical liquor on dehydration rate was studied.The liquid-liquid equilibrium data for n-butanol-water-K2CO3 system were measured at 40℃ and theoretically calculated by means of Pitzer theory and NRTL equation.Results showed that when mass ratio of potassium carbonate solution with 60.00% of mass fraction to waste pharmaceutical liquor was 1.00,dehydration rate was as high as 84.50%.n-Butanol with 99.50% of mass fraction can be distillated from organic phase.The calculated results were close to the experimental data and average absolute deviation for water phase and organic phase was 0.60% and 0.20% respectively.


Patients with tuberous sclerosis were studied to investigate the pathophysiological basis for hamartoma and neoplasia development in this disease. Chromosome banding, aberration following G‐2 x‐ray exposure, and the frequency of sister chromatid exchange were normal. Mean IgM levels were significantly elevated above those of random institutionalized control patients but not above cottage‐mate controls. Although 4 out of 10 patients did not respond to any of the skin test antigens used, tuberous sclerosis patients and controls had similar responses to in vitro lymphocyte transformation. This study failed to reveal any cytogenetic abnormalities or conclusive evidence of immune deficiency in tuberous sclerosis.

A system is presented which is able to reconstruct the physical processes after the annihilation of particles in collider rings like LEP. It can be shown that the reconstruction task belongs to the class of NP-complete problems. Neither the conventional symbol processing approach of artificial intelligence nor connectionist systems alone satisfy the requirements of the application. A hybrid system is introduced in which a genetic algorithm acts together with a model-based hillclimbing component. The power of this method is based on the interaction of a dynamically and an inferentially working module. The inherent parallelism of dynamic systems makes a implementation on a parallel architecture useful. A data parallel implementation of this algorithm on the Connection Machine Model CM-2 is described. At last the reconstruction system is applied to a classification task, the identification of the initial quark pair. The results are compared with a conventional analysis method and a neural network.

In the deep submicrometer regime, analog device design is challenging because of conflicting performance requirements for analog and digital applications. In this paper we report a simulation study of single-halo (SH) and single halo source/drain on depletion layer (SH SDODEL) n-channel MOSFETs for analog and mixed signal applications. The single halo structure has a high pocket impurity concentration near the source end of the channel and low impurity concentration in the rest of the channel. Junction capacitance for the SH SDODEL structure was optimized as compared to that in bulk SH devices and found to be 28% less. Our results shows that, in SH SDODEL MOSFETs, there is significant improvement in the intrinsic device performance for analog applications (such as device gain, gm/ID etc.) over a wide range of channel lengths. Also reduced junction capacitance is beneficial for improved circuit performance

Objective
To investigate the obstetric risk factors of neonatal hypoglycemia.

Methods
There were 92 cases of newborns who were tested blood glucose within thirty minutes after birth and identified as at risk of neonatal hypoglycemia at the First Affiliated Hospital of Dalian Medical University during September 1, 2014 to December 31, 2015 (case group). In the meantime, 92 cases of newborns with normal blood glucose level as control group were randomly selected from the same hospital by systematic sampling method during the same period. Relative risk factors which might cause neonatal hypoglycemia, such as maternal age, gravidity and parity history, pre-pregnancy body mass index (BMI), pregnancy complications, delivery mode, gestational age, birth weight, newborn gender, the incidence of premature babies, macrosomia, low birth weight infants (LBWI), large for gestational age(LGA) infants, small for gestational age (SGA) infants, twins and so on were retrospectively analyzed. Data were performed by using single factor and multiple unconditioned logistic regression analysis. This research was in line with ethics standards promulgated by the ethical review committee of the First Affiliated Hospital of Dalian Medical University, which had been approved by the committee.

Results
①There were significant differences between two groups in the aspects of neonatal gestational age, blood glucose concentration within thirty minutes after birth, and incidence of premature infants and LBWI (t=-5.081, t=-19.907, χ2=8.725, χ2=5.545; P 0.05). ②Among 92 neonatal hypoglycemia infants (case group), 83 cases (90.2%) had no clinical symptoms, another 9 cases had clinical manifestations (9.8%), but not typical.③In case group, the pre-pregnancy BMI and the incidence rate of maternal pre-pregnancy overweight or obesity were both higher than those of control group[(23.9±4.5)kg/m2vs (21.5±2.7)kg/m2, 45.7% vs 12.0%], and both the differences were statistically significant (t=4.245, χ2=25.468; P 0.05). ④ The incidence rates of pregnancy combined diabetes mellitus, gestational hypertension disease, cesarean section and elective cesarean were higher than those of control group(40.2% vs 12.0%, 32.6% vs 6.5%, 94.6% vs 52.2%, 63.2% vs 41.7%), and the differences were statistically significant (χ2=19.054, 19.892, 42.307, 5.819; P 0.05). ⑤ Multiple unconditional logistic regression analysis showed that, maternal pre-pregnancy overweight or obesity, pregnancy combined diabetes mellitus, cesarean section and premature infants were risk factors of neonatal hypoglycemia(OR=3.355, 3.368, 9.174, 4.981; 95%CI: 1.416-7.950, 1.369-8.286, 3.142-26.787, 1.187-20.898; P<0.05).

Conclusions
Controlling pre-pregnancy weight, strengthening the standard management of diseases such as diabetes and hypertension disease during pregnancy, decreasing obstetric complications, reducing the incidence rate of cesarean section, shortening the preoperative fasting duration and giving preoperative rehydration, are all playing positive roles in reducing and preventing the incidence of neonatal hypoglycemia.

This article presents a partial-power postregulated LLC resonant converter. In the proposed topology, the input power is first transferred to the secondary side of the transformer through the LLC-DC transformer converter to achieve galvanic isolation and voltage conversion functions. Then, most of the power is directly transmitted to the load side, and only a small portion of the power is converted to the output side by the partial-power processing converter. Therefore, unlike the two-stage solution, the converter proposed in this article achieves output voltage regulation while minimizing the efficiency loss caused by the two-stage conversion. The operating principle of the proposed converter is analyzed, and the system prototype is constructed. Experimental result validates the correctness of the analysis and proves the feasibility of the proposed converter.


concepts of simulation of rain falling effects using: Delta3D Particle System Editor, which renders rain falling effect using two static raindrop textures, and Physical Properties-Based Method which renders rain falling effect by mapping the background scene onto raindrops according to their refraction property. We observe that the reflection property of a raindrop is also important since it contribute to its visibility in the dark regions. Hence, we propose a new method that takes into account both refraction and reflection property of raindrop. increase in the computational speed of graphics hardware in recent times. This power afforded by modern graphics cards enables the possibility of simulating complex environmental phenomena.

Lung cancer is considered as one of the most significant causes of deaths globally. Diagnosis at an initial stage, using computed tomography chest scans could give a better chance to the patient to survive by providing an opportunity for effective care plans and treatment. We propose a new deep-learning method to learn high level image representation towards attaining a significant classification accuracy. This technique consists of three important steps, which are data preparation, pre-processing of data, and classification. The proposed model is a multi-layer convolutional neural network (CNN) that uses different convolutional layers, pooling layers, flatten, dense layers, dropout layers, and performs classification. Two pretrained models which are VGG16 and Densenet, that takes weights using ImageNet pretraining are also employed. This work utilized chest CT-scan image dataset. The dataset contains the images in PNG or JPG format which are suitable for the model. The data contains three types of chest cancers which are adenocarcinoma, large cell carcinoma, and squamous cell carcinoma as well as normal controls. Our experimental results showed that the proposed models achieved the maximum accuracy of 99.75% using the multi-layer CNN model, of 97.25% using Densenet-201, and of 96% using VGG-16.


An Interdigital-H (IH) linac has been used for ion acceleration in low beta range. It can realize a resonant cavity of a convenient size at low frequencies and higher shunt impedance at low energy range. These characteristics are advantageous especially for heavy ion acceleration. Since the shunt impedance of the IH linac reduces according to the increasing of beam energy, the linacs operated by the TM010 mode such as an Alvarez type and a coupling cavity type are adopted for medium and high energy range. However, we propose the new IH linac using the TE11n mode, the higher order mode IH (HOM-IH) linac. By using the higher order mode, the resonance frequency is higher than that of the IH linac. This property is suitable for middle and high beta linacs, and a proton linac as well. The design of the cavity structure and the possibility are presented.

The magnitude of quantum fluctuations of the charge of a fractionally charged soliton is calculated. The soliton charge operator is defined as ${\stackrel{^}{Q}}_{s}={\stackrel{^}{Q}}_{f}\ensuremath{-}〈0|{\stackrel{^}{Q}}_{f}|0〉$, where ${\stackrel{^}{Q}}_{f}$ is the integral of the charge-density operator sampled by a function $f$ peaked at the position of the soliton, and falling smoothly to zero on a scale $L$. $|0〉$ is the ground state of the system in the absence of solitons. It is shown that the mean-square fluctuation of ${\stackrel{^}{Q}}_{s}$ taken about its fractional average value ${Q}_{s}$ vanishes as $O(\frac{{\ensuremath{\xi}}_{0}}{L})$ for $Lgg{\ensuremath{\xi}}_{0}$, where ${\ensuremath{\xi}}_{0}$ is the width of the soliton. Thus, as $L\ensuremath{\rightarrow}\ensuremath{\infty}$, the soliton is an eigenfunction of the charge operator with fractional eigenvalue. We also show that the portion of the charge fluctuations that are due to the soliton falls as $\mathrm{exp}(\frac{\ensuremath{-}L}{{\ensuremath{\xi}}_{0}})$ as $L\ensuremath{\rightarrow}\ensuremath{\infty}$. Nonetheless, the charge of the entire system, including all solitons, is integral.


We present a suite of codes for approximating Lyapunov exponents of nonlinear differential systems by so-called QR methods. The basic solvers perform integration of the trajectory and approximation of the Lyapunov exponents simultaneously. That is, they integrate for the trajectory at the same time, and with the same underlying schemes, as integration for the Lyapunov exponents is carried out. Separate codes solve small systems for which we can compute and store the Jacobian matrix, and for large systems for which the Jacobian matrix cannot be stored, and it may not even be explicitly known. If it is known, the user has the option to provide its action on a vector. An alternative strategy is also presented in which one may want to approximate the trajectory with a specialized solver, linearize around the computed trajectory, and then carry out the approximation of the Lyapunov exponents using codes for linear problems.Copyright © 2009 by ASME

This paper is largely observational. It discusses shifts in capitalization practices in marketing texts in Latvian. Two of the observed shifts are changes in accepted Latvian orthography (in Latvian texts) and one is an extension of Latvian changes into English texts written in Latvia. One of the Latvian shifts may be due to external influence and one is from internal sources. These changes are considered as matters of orthographic change, cultural change, the introduction of new (or previously little utilized) communication channels and tools and demonstration of the evolution of new communication rules. The paper provides some hypotheses about what may cause this and makes some observations about what this reflects about culture and language and how these are applied to other languages.

We present new algorithms for refining the estimates of the eigenvectors of a real symmetric matrix. Using techniques from calculus, we show that the algorithms converge locally cubically fast. By this we mean that locally all eigenvalue-eigenvector pairs simultaneously converge at a cubic rate. This is in contrast to well known shifted QR algorithms, which depending on the shifting strategy employed, have only one (or at most a small subset) of the eigenvalue-eigenvector pairs converging cubically at any one time. The algorithms are well suited to the situation where one needs to compute the eigenvectors of a perturbed matrix A + E based on a good estimate of the eigenvectors of a matrix A. Such a situation frequently appears in tracking applications.


PressureCast Steel Pipe (PCSP) utilizes a patented manufacturing process to pre-compress the concrete or mortar lining in steel pipe. The combined steel-concrete wall stiffness of PCSP makes the pipe much stiffer and potentially easier to install, due to the use of native materials and lower compaction requirements, than ordinary steel pipe. This paper presents the set-up and execution of three combined load tests on 60" PCSP. New methods of observing the performance and recording the data for combined load testing were developed, which provided a basis for revision of the pipe design criteria. The results confirmed the efficacy of these tests in confirming the design procedure and criteria.


The heteropolyacid H5PMo10V2O40·34H2O was found to be an efficient oxygen activating agent in palladium-catalyzed reactions. Aerobic 1,4-oxidations of conjugated dienes were carried out by employing a triple catalytic system consisting of palladium−quinone−heteropolyacid. With this system a mild electron transfer from the organic substrate to molecular oxygen occurs. 1,4-Diacyloxylations and 1,4-dialkoxylations were studied using this mild reoxidation system. 1,4-Diacetoxylation of 1,3-cyclohexadiene was studied in some detail. Some advantages of the heteropolyacid over previously employed metal macrocycles are high stability, easy access to an active catalyst, and simpler workup procedures.


This paper evaluates the performance of maximum-likelihood sequence detection (MLSD) receivers for nonlinear bandlimited satellite channels which employ QPSK and 8-PSK modulation formats. The optimal receiver for a nonlinear satellite channel is a matched-filter bank followed by a Viterbi detector (MFB-MLSD). The MFB-MLSD receiver may be high in complexity, where the filter bank complexity grows exponentially with the channel memory. Consequently, a suboptimal single receive filter receiver (SF-MLSD) is considered, and the effect of the pulse shape on channel memory is also studied. A finite-state machine (FSM) description of the channel is used for evaluating the nonlinear satellite channel. For all cases considered, the MFB-MLSD receiver gives a small performance loss compared to the AWGN channel, and the SF-MLSD receivers, when square-root raised cosine pulse shaping is employed, give little performance loss relative to the MFB-MLSD receivers.


This manuscript examines three separate but inter-related research questions. After reviewing scientifically relevant literature in the first chapter, the second chapter compares the prevalence of carotid plaque among the three major race-ethnic groups in the Electron-beam computed tomography, Risk factor Assessment among Japanese and U.S. Men in the Post-World War II birth cohort (ERA JUMP Study). This study shows that carotid plaque, a biomarker of subclinical atherosclerosis, is significantly lower among men in Japan and South Korea than in the US. This difference is independent of traditional risk factors of coronary heart disease (CHD). Further, it shows that only age, hypertension and diabetes are cross-sectionally associated with the prevalence of carotid plaque.
The third chapter examines the association between brachial-ankle pulse wave velocity (baPWV) and coronary artery calcification (CAC), an established biomarker of coronary atherosclerosis and a strong predictor of future CHD risk. baPWV is a non-invasive and convenient measure of arterial stiffness and is clinically used in eastern Asia as a tool for assessing future cardiovascular risk. This study found that increasing baPWV is cross-sectionally associated with increasing prevalence of CAC among middle-aged men in the ERA JUMP study, including White men in the US.
The final and fourth chapter of the manuscript examines the association of serum levels of soy isoflavones and equol, with CAC among Japanese men in Japan. Japanese consume soy and soy products regularly. Isoflavones are a component in soy and are known to have anti-atherosclerotic properties. Equol is a potent isoflavone produced from the dietary isoflavone daidzein by action of intestinal bacteria. This study shows that individuals who have bacteria to convert daidzein to equol, i.e. equol producers, have lower CAC than equol non-producers.
These three studies, individually and as a whole, contribute significantly to the public health knowledge. Japan has significantly lower atherosclerosis than the US in spite of a similar level of risk factors. Several lessons may be learned from Japan in an effort to reduce CHD mortality in the US. baPWV may potentially provide similar information to clinicians as CAC without exposing the patient to radiation.

Millions of students are investing significant time in playing online games. Why not use these games to promote responsible behaviours among young people? In this study, we tested the hypothesis that the introduction into a serious game of appropriate mechanisms to support motivation, together with effective ergonomic design, can enhance young people's learning through gameplay. We developed a serious game, Water Game, using a generic shell for serious games (GSSG), and tested it with 156 secondary school students. The results show a high degree of student appreciation for the motivational support mechanisms and ergonomic conditions that were implemented in the game to support attitude change. Recommendations are offered to developers of serious online games for learning purposes.


We perform measurements on an AlGaAs/GaAs double‐quantum‐dot structure, where dots are separated by an opaque barrier and each dot conductance is measured independently and simultaneously. We measure the Coulomb blockade oscillations (CBOs) for each dot when the structure is configured for one and two dots. When configured as a single‐dot device, we sweep the backgate and observe different CBO periods for each dot measured independently, implying dots of different sizes. When the device is configured for two dots, we observe strongly modulated CBOs in the larger dot while CBOs in the smaller dot exhibit almost no influence due to the changing charge of the larger dot. From this experiment, we have realized a charge detection scheme where we observe strong coupling in the detector signal in addition to the detector exhibiting minimal effect on the dot being measured. For an implementation of quantum‐dot cellular automata (QCA), (1) cells must couple capacitively and (2) one must be able to detect electron ...

The instrument has been designed to fulfil all the required conditions of versatility, vacuum, accuracy, simplicity, ease of construction and operation, and includes a number of novel features including an ultra-high vacuum specimen holder and airlock, totally enclosed magnetic lens and scanning coil assemblies, and a bakeable electron gun and energy filter.


Student Beliefs and Self-Reported Juvenile Delinquency: A Test of General Strain Theory Jacqueline Nicole Canady The purpose of this study is to test Robert Agnew's General Strain Theory. The researcher applied the theory to secondary data of high school sophomores utilizing Educational Longitudinal Survey of 2002. The study sought to understand whether Agnew's strain theory is applicable to high school environments. The findings indicate some support for Agnew's Revised Strain Theory. Conversely, sex is substantially insignificant concerning self–reported juvenile delinquency within schools. Furthermore, without accounting for students' upbringing and socioeconomic background Agnew's General Strain Theory cannot explain differences in race and delinquency. In conclusion, the study suggests further research of Agnew's theory, concerning both race and sex. Dedication I would like to dedicate this work to my parents, Herman G., and Barbara L. Canady


A digital gradient-ascent algorithm is presented to identify and maintain the peak power operating point of a photovoltaic (PV) source with variable I–V characteristics. The approach employs a low-level dither, realized by a one-bit, 64-sample pseudorandom noise (PN) sequence, to perturb the duty cycle of a boost converter that extracts energy from a PV source for battery charging. The digital-domain optimization process operates continuously in the background, and is robust against measurement noise, offset, jitter, and the inherent large-signal nonlinear dynamics of the boost converter. Acquiring a single sample in each switching cycle, i.e., no oversampling for the analog-to-digital converter (ADC), the digital processor consists of a few adders, flip-flops, and one multiplier, which, in conjunction with the ADC, can be integrated with the driver integrated circuit (IC) of the boost converter for very low cost. Simulation verifies the tracking effectiveness of the proposed technique, and demonstrates a stable operation in presence of large power-on and load transients, with an average output power of ≥ 98.5% of the peak value consistently achieved in steady state.


Patients with larger breast sizes have been considered to be contraindicated for hypofractionated radiation therapy. In the present retrospective study, we analyzed the dosimetric and clinical toxicity outcomes of patients with different breast sizes and treatment positions. We conclude that three‐dimensional conformal radiotherapy (3D‐CRT) hypofractionated radiation therapy can be therapeutically applied regardless of the breast size and treatment position. The aim of this study is to report a comparison of the dosimetry and toxicity of 3D‐CRT on patients with different breast volumes who received whole‐breast hypofractionated radiation therapy.


Dispersion of ground-penetrating radar (GPR) waves can occur when they are trapped in a layer. In this paper, we analyze the modal propagation of GPR pulses through a layer of ice that is overlying water. Dispersed transverse electric (TE) waves that are trapped in the waveguide have larger amplitudes than the critically refracted waves that travel through air, whereas the transverse magnetic (TM) critically refracted waves traveling through air are more dominant than the trapped dispersed TM waves. This can be explained by the leaky waveguide behavior of the ice layer. The reflection coefficients for the waves incident on the ice-water interface show that the TM modes are more leaky than the TE modes. Still, clear dispersion is observed in both cases, which depends on the permittivity and thickness of the ice. Similar to inversion of dispersed Rayleigh waves, these parameters can be estimated by calculating phase-velocity spectra, picking dispersion curves, and inverting the dispersion curves using a combined local and global minimization procedure. Synthetic data show several higher order modes of which separate and combined inversions return the input modeling parameters accurately. Experimental data acquired on a frozen lake show strong dispersion for the TE and TM modes. The phase-velocity spectra of the field data show three TE and four TM modes of which separate and combined inversion of different modes return similar values for the ice thickness and known permittivity of ice. Due to the more leaky behavior of the TM modes, the TE inversion is better constrained and more suitable for inversion.


We analyze transitions between heterotic vacua with distinct gauge bundles using two complementary methods – the effective four‐dimensional field theory and the corresponding geometry. From the viewpoint of effective field theory, such transitions occur between flat directions of the potential energy associated with heterotic stability walls. Geometrically, this branch structure corresponds to smooth deformations of the gauge bundle coupled to the chamber structure of Kähler moduli space. We demonstrate how such transitions can change important properties of the effective theory, including the gauge symmetry and the massless spectrum. Geometrically, this study is divided into deformations of the vector bundle which preserve the rank of the gauge bundle and those which change the rank. In the latter case, our results provide explicit solutions to a class of Li‐Yau type deformation problems. Finally, we use the framework of stability walls and their effective theory to study Donaldson‐Thomas invariants on Calabi‐Yau threefolds.


Partially modified polystyrene containing OH groups was shown to be miscible with a number of counterpolymers which contain proton acceptor groups, and the hydrogen bonds were formed in the solid state of these systems, In this paper we pay attention to the kinetics of phase separation and phase diagram of such kinds of hydrogen bonded blends,PS(OH) was synthesized by copolymerization of styrene with p-(hexafluoro-2 hydroxyl isopropyl) α-methyl styrene. A binary blend of PS(OH) containing 1.5mol% of OH gronp and poly(butyl methacrylate) showed the LCST behavior. The critical point was not in the minimum of spinodal curve and binodal curve owing to the polydispese of composition of PS(OH).The kinetics of phase separation was studied by the temperature jump light scattering techniqne. The early stage of spinodal decomposition follows the Cahn-Hilliard-Cook's linear theory. In the later stage of spinodal deomposition, the evolution of the maximum intersity I_m and the corresponding wave mumber q_m obe Siggia's model for the blend with critical compostion, and Lifshitz-Slyozov model for the blend with non-critical composition, respectively.


A pavement evaluation method has been developed on the basis of elastic theory by which structural properties of a pavement can be derived from the surface deflection and the shape of the deflection bowl under a test load. The method generally expresses the structural quality of an existing pavement in terms of effective layer thicknesses and Young's moduli for the materials. Results are better with instruments using short loading times, like the Falling Weight Deflectometer, than with slow-speed instruments like the Benkelman Beam. The Falling Weight Deflectometer has proved to be an accurate, reliable and simple instrument for pavement evaluation. The force level and loading time adequately represent actual traffic. Values of effective asphalt layer thicknesses derived from the deflectometer results showed good agreement with values obtained from cores or construction reports. The structural properties derived from deflection measurements can be used in the Shell Design Charts to determine a required overlay thickness.


Haefliger's theorem (3) that the group of isotopy classes of embeddings of Sx in Sn when n − x > 2 is isomorphic to the triad group πx+1(G; G(n − x),SO), where G(n − x) is the H-space of homotopy equivalences of Sn−x−1 of degree 1, , and SO is the stable special orthogonal group, is generalized in this paper by replacing Sx and Sn by arbitrary compact connected smooth manifolds Xx, Mn without boundary. The embedding and knot problems are reduced to homotopy theory. The question of P.L. manifolds is discussed in section 4. The case Mn = Sn will be considered first; the generalization is stated in section 3.


Aimed at the problem that it is difficult to describe the non linear properties of water turbines and the complicated non linear properties of the Francis turbine governing system (FTGS), a Francis turbine neural network model (FTNNM) is established by using the strong approaching ability of forward feedback neural network. In the model, the properties of discharge and efficiency properties are described in the off line train by adoption of Levenberg Marquardt algorithm, which has the effect of quick convergence and high precision. After trained, the model can be used as a non linear section to compose a non linear emulation system together with other modules under the circumstances of SIMULINK of MATALAB. This system formed can realize non linear emulation at different operation conditions, and can find the change rules of internal parameters of Francis turbine rapidly and accurately. Thus, the system can provide a good foundation for the study on the control strategies for Francis turbine governing system (FTGS).

The anti-synchronization of two nonlinear-coupled spatiotemporal chaotic systems is discussed. A special nonlinear-coupled term is constructed through suitably separating the spatiotemporal chaotic systems to linear and nonlinear terms, and anti-synchronization of two two-dimensional coupled map lattices is realized. The nonlinear-coupled method is further generalized to anti-synchronize the complex networks composed of two-dimensional coupled map lattices. The artificial simulation results show that this method is still effective.


This chapter examines the legal ambiguities surrounding a war that might not be a war, against an elusive enemy whose existence as an organised entity is sometimes cast in doubt. Military operations are carried out under the mantle of this war and casualties and destruction have followed, rendering the analysis and classification a crucial matter. The possibilities for classification, as well as the views of parties concerned are examined, as are the repercussions for operations conducted within this paradigm.

The equivalent circuit model is outlined on the basis of immittance spectroscopic measurements and the parameters' estimation made in the input file till a valid run is achieved. The immittance spectroscopic measurements include the variations of resistance, capacitance, conductivity, electric modulus etc. with respect to frequency and temperature.


Diapause termination and mortality were examined in oversummering eggs of 'H. destructor' collected from two pasture sites near Leeton, New South Wales, which differed in soil type and drainage. The effect of soil type and moisture on these factors was also investigated experimentally. Diapause termination was less reliable and mortality higher in eggs obtained from poorly drained clay than from well drained sandy loam. Soil type and moisture did not affect timing or extent of diapause termination. However, moisture increased mortality. Mortality of eggs on permanently wet sand was significantly greater than in any other treatment. The results from this study indicate that summer rainfall can have a deleterious effect on survival of oversummering eggs of 'H. destructor', particularly on heavy poorly drained soils.


Deep learning has achieved promising performance in hyperspectral image (HSI) classification. Training deep models usually requires labeling massive HSIs, which, however, is prohibitively time-consuming and expensive. To fill in the gap, this article proposes a novel meta-learning method for HSI few-shot classification that conducts HSI classification with a few labeled samples. Specifically, we introduce the Earth mover's distance (EMD) as a metric. The designed EMD metric learning module aims to calculate the similarity of paired embedding features by decomposing embedding features into a set of local representations. The EMD metric aims to find the optimal matching flows between local representations that have the minimum matching cost. Furthermore, we attempt to learn class prototype representation for each hyperspectral class using the EMD metric. The proposed network effectively learns general knowledge from base HSIs and transfers such knowledge to the classification of novel HSIs. We conduct HSI few-shot classification by training on three base HSIs and classification on three novel HSIs. Extensive experimental results on three novel HSI datasets demonstrate that the proposed model outperforms the existing state-of-the-art HSI methods, including two HSI few-shot methods.


In 96-week extension data from a Phase 3 trial the tumor necrosis factor (TNF) inhibitor shows sustained improvements in symptoms of spondyloarthropathies, with no signs of new adverse events.


Immunohistochemistry was used to study the kinetics of B lymphocytes (B‐lys) In the early stages of the localized inflammatory response Induced in SMA mice by the subcutaneous injection of lipopolysaccharide (LPS). At the injection sites, medium‐sized B‐lys formed early inflammatory lesions with neutrophils and activated macrophages on days 1 and 2. The B‐lys were morphologically similar to monocytes, but were not stained with Mac1 antibody. Remarkably the B‐lys showed the phenotypes of B220+, lgM+, IgD (slight to negative), Ly‐1‐ and CD23‐ by double immunohistochemi‐cal staining. The B‐lys were also positive for alkaline phosphatase. Consequently the B‐lys could be identified as monocytoid B‐lys or marginal zone B‐lys. Plasmacytic B‐lys and plasma cells were first observed on days 3 and 4, but no lymphoid follicles were found at the injection sites. In the inguinal lymph nodes, the same B‐lys responses were mainly induced in the paracortical lesions (T cell areas) preceding the formation of activated germinal centers (GC). These findings suggested that the B‐lys, induced by injections of LPS, matured into plasma cells in the localized inflammatory lesions independent of GC, and that they were different from follicular B‐lys.


The use of transformation optics concept for the design of miniaturized radiating devices is investigated. By choosing transformations that compress space, and then match it to the surrounding radiation environment, we are able to alter the physical size of the embedded source. We show that a small aperture antenna can then behave as one with a large aperture. A study of the transformation of the space metric and the material parameter calculation is presented. Simulations are performed to validate the proposed approach at microwave frequencies. This study paves the way to interesting applications in telecommunications and aeronautical domain.


In a voltage control apparatus of an alternator mounted on a vehicle, the parameter and the equation, which are established based upon the power generation characteristic and the electromagnetic specification of the alternator, are not required, and both an ON-duty rate of an ON/OFF logic of a voltage applied to an energizing coil and a logic frequency can be established under stable condition within a preselected frequency range. The alternator voltage control apparatus is arranged by employing: a first logic output means for comparing a voltage generated by the alternator with a target voltage to obtain a magnitude logic which is outputted as a first ON/OFF logic; and a second logic output means for outputting as a second ON/OFF logic, a PWM internal output logic in which an ON-duty rate is increased/decreased based on the first ON/OFF logic by an increased/decreased amount defined by considering a time constant of the energizing coil. In this alternator voltage control apparatus, a logically processed result between the first ON/OFF logic and the second ON/OFF logic is used as an ON/OFF logic of a voltage application to the energizing coil.

We present a framework for designing distorting mechanisms that allow remotely operating anomaly detectors while preserving privacy. We consider the problem setting in which a remote station seeks to identify anomalies using system input-output signals transmitted over communication networks. However, disclosing true data of the system operation is not desired as it can be used to infer private information -- modeled here as a system private output. To prevent accurate estimation of private outputs by adversaries, we pass original signals through distorting (privacy-preserving) mechanisms and send the distorted data to the remote station (which inevitably leads to degraded monitoring performance). We formulate the design of these mechanisms as a privacy-utility trade-off problem. We cast the synthesis of dependent Gaussian mechanisms as the solution of a convex program where we seek to maximize privacy quantified using information-theoretic metrics (mutual information and differential entropy) over a finite window of realizations while guaranteeing a bound on monitoring performance degradation.

Statistical analysis was done with chi-square/Fisher's Exact Test using SPSS version 16.


Introduction : Forward head posture, which occurs often in conjunction with increased curvature in the upper body and rounded shoulder, is one of the most common postural deviations. Over time, this poor posture can contribute to the development of neck pain and shoulder dysfunction. Therefore, the purpose of this study is to design and develop a forward head rounded shoulder posture corrective orthosis (FHRSO) and its immediate effect on craniovertebral and protraction-retraction angles in people with postural deviations in the upper body. Materials and Methods : Thirty men aged between 18 and 60 years with a forward head posture disorder (craniovertebral angle less than 42.5 degrees) participated in this study. Correspondingly, the immediate effect of the newly designed orthosis, namely FHRSO was investigated via measuring two variables, craniovertebral and protraction-retraction angles in the standing position by taking lateral view photographs. Results: Both craniovertebral and protraction-retraction angles were significantly increased following the FHRSO wearing in comparison with no orthosis condition ( P <0.001). Conclusion: Our findings indicate that a FHRSO orthosis can be effective for correcting the forward head and rounded shoulder posture in persons with postural deviations in the upper body.


This paper presents the framework of a novel approach to combine multi-modal sensor information from a network of distributed smart nodes possessing audio and video modalities for gaining valuable supplementary information compared to traditional video-based surveillance systems or even just CCTV systems. The nodes are equipped with wireless communication modules allowing high-range, medium-bandwidth, and secure communication in a ldquocable-replacementrdquo fashion. Some of the nodes also possess wired Ethernet connections to allow the transport of video streams to the supervisor. In a stepwise procedure the nodes first discover neighbor nodes by means of wireless connection strength and then try to find overlaps on the semantic level by utilization of the loopy belief propagation algorithm. This procedure ensures scalability over the network and allows establishing a global view of behavior in some region shared by several nodes. The processing architecture including the physical sensor nodes is called SENSE (smart embedded network of sensing entities).


This thesis, Bard in the Gondola, Barred in the Ghetto: Operatic Adaptations of Shakespearean Text and Italian Identity in the Late Nineteenth Century, is based on the comparison between two texts. The first is William Shakespeare's first quarto edition of The Merchant of Venice. The second is the 1873 vocal score and libretto of Ciro Pinsuti and G.T. Cimino's opera, Il Mercante di Venezia: un melodramma in quattro atti. The contrast between the two works is made within the context of Italian unification, nationalism and identity juxtaposed with the literary and philosophical trends of the nineteenth century that impacted the way in which the opera was created and received by Italians. Central to the work is the theme of identity. After its final unification in 1871, Italy was nominally one country, a nation strong and cohesive. However, there were several cultures within the society that had to form a new national spirit by either rejecting their old, local traditions and beliefs and molding an entirely new identity or shaping together bits and pieces from each Italian experience that reflected the division of powers present in the peninsula for centuries. Religion, gender and ethnicity all factor into an individual's Italian-ness and are all examined in the Pinsuti opera. The use of theatre as a means of shaping this discussion continued into the twentieth century of Italy, as the nation still struggles to unite a divided culture of north and south, of progress and tradition.


The hypocalcaemic effect of synthetic porcine calcitonin in hypercalcaemic crisis has been studied in a 49-year-old man suffering from hypernephroma with skeletal metastases and a 10-year-old boy with a primary hyperparathyroidism. In both patients calcitonin induced prompt reduction of serum calcium concentration and pronounced clinical amelioration. This made possible successful removal of a parathyroid adenoma in the young boy. No undesirable side-effects were observed during treatment with calcitonin.


Ethnographic characterizations of pastoralists as egalitarian have recently been contested on the grounds that new studies have demonstrated a widespread inequality in livestock ownership, thus proving that the notion of pastoral egalitarianism is a myth. This revisionist rejection of the egalitarianism of pastoralists appears difficult to sustain after examination of the literature. Ethnographic accounts show a wide range of pastoral societies, some more hierarchical and some quite egalitarian, and this variation was well recognized by at least 1940. "Egalitarian" is used in the literature to characterize pastoral tribesmen primarily in a political rather than an economic sense. Differences in livestock ownership were recognized by ethnographers characterizing the peoples they studied as "egalitarian", but these differences were known not to cause either social stratification or economic class differentiation. To suggest as the revisionists do that all societies and cultures are characterized by inequality removes the power from the conceptual continuum "equality ⟷ inequality" and obscures the real differences from society to society and time to time.


Coconut, a major plantation crop in tropics is constrained with both biotic and abiotic factors. Amongst the biotic constraints, termites are the major soil insect-pests in the orchard that can cause damage up to 20% particularly in nursery. In India, termites are found in almost all the coconut growing tracts, but not considered serious except in the nursery. Coconut is grown in cultivated, and in uncultivated (wild/semi-wild) situations in our country, are ravaged by termites mostly by Odontotermes spp. Other, coconut growing countries are affected by other termites (species of Microtermes, Microcerotermes, Coptotermes, Nasutitermes and Neotermes). Worldwide, termites attacking coconut comprise of three families (Kalotermitidae, Rhinotermitidae and Termitidae) and eleven genera. In India, termites attacking coconut are exclusively subterranean unlike in other regions (mostly Island nations), where arboreal termites are included. In the latter case, role of ants as biocontrol agent is documented. Microbial pesticides as such are not recommended, is being reasoned out. This review deals with distribution, nature of damage and management aspects in the associated context. Integrated pest management (IPM) strategies, and few indigenous traditional knowledge (ITK) are also highlighted.


The objective of this study mainly focuses on Anita Desai's Protagonists and how far they are different from society and their self. Anita Desai's basic parameters of exploration attempted to emphasise the similarities and differences between different characters' predicaments. Her fictions starkly emphasise how little people know about many important aspects of themselves and their universe. It offers a sensitive and penetrating study of the complex mental activity that influences human thought and behaviour. The narrative strategies employed by her reveal both her creative instincts and the critical distancing that imparts an ironical aspect to her presentation. Her writing exposes to us the tormented thoughts and perplexed actions of her characters, who are sensitive normal people. At the same time, by showing at least a few of her protagonists as achieving her faith in the human ability to critically examine and reorient faith.


Submitted for the MAR08 Meeting of The American Physical Society Orientational Relaxation in Simulated Polymer Melts TAYLOR DOTSON, JOHN MCCOY, New Mexico Tech, JOANNE BUDZIEN, DOUGLAS ADOLF, Sandia National Laboratories, KEENAN DOTSON, JULIEANNE HEFFERNAN, New Mexico Tech — The orientational relaxation of simple polymer chains was studied using second Legendre polynomial autocorrelation functions. Such functions are commonly fit with a Kohlrausch-Williams-Watts (KWW) stretched exponential form. The value of the stretching parameter, β, and the degree that it changes as the glass transition is approached are both of physical interest. In the current project, a novel approach to determining the value and variation of β from molecular dynamics simulations is implemented. The methodology is found to produce KWW fits of high accuracy. Moreover, the stretching parameter, β, is found to collapse to a single-valued function of the decay timescale τ regardless of thermodynamic path. Connections are drawn to experimental results and theoretical implications of the research are discussed. Taylor Dotson New Mexico Tech Date submitted: 23 Nov 2007 Electronic form version 1.4


ABSTRACT This essay analyses the French film 120 BPM (Campillo 2017) in relation to its aesthetics and critical reception in the context of scientific advances in human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) therapy, as well as revised socio-cultural attitudes towards, and political strategies for dealing with, the disease. It argues that the treatment trajectory of the virus has been paralleled by a transition in the way that the disease is both represented and received in media, film, and television. This is because advances in therapy and understanding of the disease now render it much less threatening, and, although AIDS remains a serious public health concern in certain regions, public attitudes towards the virus have correspondingly shifted. Such a refocusing reverberates in the visual style of 120 BPM, particularly its cinematography and framing, which consistently positions the spectator amidst the HIV/AIDS community. Although the film focuses on a period in the 1990s when survival rates were still low and death rates rising, it was paradoxically released at a time of relative optimism regarding the prognosis for HIV/AIDS, and thus presents a more upbeat narrative that achieved widespread critical acclaim.


Intrusion detection is one of the key technologies in network security. With the diversification and intelligence of network intrusion behaviors, it is difficult for traditional intrusion detection algorithms to abstract the features contained in the intrusion behaviors, and there are some shortcomings in the performance of intrusion detection. Therefore, this paper proposes an intrusion detection algorithm based on deep belief networks and three-way decisions. Firstly, using deep belief network to extract features from high-dimensional data, and a multi-granularity feature space is constructed after multiple feature extraction. Then, three-way decisions theory is used to classify the data in positive and negative domains according to the threshold, the classifier based on the three-way decisions theory makes immediate decisions on intrusion or normal data. For the uncertain network behaviors in the boundary domain, using KNN classifier according to the characteristics of different granularity to do further analysis. Experiments on KDD CUP 99 and NSL-KDD data sets show that this algorithm can improve the performance of intrusion detection.


Atmospheric residue desulfurization (ARDS) process is extensively used in upgrading of heavy petroleum oils and residues to more valuable clean environmentally friendly transportation fuels and to partially convert the residues to produce low-sulfur fuel oil and hydrotreated feedstocks. Graded catalyst systems in multiple reactors are used in the process in order to achieve hydrodesulfurization (HDS), hydrodemetallization (HDM), hydrodenitrogenation (HDN), and conversion of residues to distillates at desired levels. The characteristics of the feedstocks processed in different reactors are significantly different. The quality of the feed entering the second reactor is strongly dependent on the operating severity in the first reactor and can have an important impact on the performance of the catalysts in the following reactor with regard to various conversions and deactivation rate. In the present work, a systematic study was conducted on the effect of two industrial catalyst types, namely, MoO3/Al2O3 (HDM)...


Although women's representation in STEM fields and occupations has increased, science and math continue to be stereotyped as male domains. This paper links psychological and sociological explanations for gendered disparities in STEM by examining the relationship between the local "micro-situational" female learning environment and the gender gap in academic self-concept in math and science. We applied hybrid models to TIMSS 2015 data comprised of a pseudo-panel of repeated measures for individual student and peer achievement, academic self-concept, utility value, and interest-enjoyment value in math/science (at age 14). We analyzed data from three countries, including a subsample of students who were taught by the same teacher in both math and science, thus eliminating unobserved teacher heterogeneity. Results indicate that female peer climate in the classroom is important for understanding how girls' self-concept in math/science is formed, even though it was unrelated to the gender gap.


Wireless ad hoc network consists of inexpensive nodes that form a mobile communication network. Due to limitations of the transmission range, the nodes rely on each other to forward packets such that messages can be delivered across the network. The selection of the path along which a packet is forwarded from the source node to the destination node is done by the routing algorithm. Most commonly used routing algorithms, though effective for nonreal time applications, cannot handle real-time applications that require strict delay bounds on packet delivery. In this thesis, we propose a routing protocol that ensures timely delivery of real time data packets. The idea is to route packets in such a way that irrespective of factors like traffic load and node density, the average delay remains within acceptable bounds. This is done by carefully accessing the resources available to a route before a session is admitted along that route. Each link in the route is checked for sufficient bandwidth not only for the new session to be admitted but also for the sessions that are already using that link. The new session is admitted only if the admission does not violate the delay bounds of any on-going sessions. This method of route selection coupled with per-hop link reservations allows us to provide bounds on the delay performance. Extensive simulation experiments have been conducted iii that demonstrate the performance of the proposed routing protocol in terms of throughput, session blocking probability, packet drop probability, average path length, and delay.


The purpose of this Analysis/Model Report (AMR) is to update and document the data and subsequent analyses from ambient field-testing activities performed in underground drifts of the Yucca Mountain Site Characterization Project (YMP). This revision updates data and analyses presented in the initial issue of this AMR. This AMR was developed in accordance with the ''Technical Work Plan for Unsaturated Zone (UZ) Flow and Transport Process Model Report'' and ''Technical Work Plan for UZ Flow, Transport, and Coupled Processes Process Model Report. These activities were performed to investigate in situ flow and transport processes. The evaluations provide the necessary framework to: (1) refine and confirm the conceptual model of matrix and fracture processes in the unsaturated zone (UZ) and (2) analyze the impact of excavation (including use of construction water and effect of ventilation) on the UZ flow and transport processes. This AMR is intended to support revisions to ''Conceptual and Numerical Models for UZ Flow and Transport'' and ''Unsaturated Zone Flow and Transport Model Process Model Report''. In general, the results discussed in this AMR are from studies conducted using a combination or a subset of the following three approaches: (1) air-injection tests, (2) liquid-release tests, and (3) moisture monitoring using in-drift sensors or in-borehole sensors, to evaluate the impact of excavation, ventilation, and construction-water usage on the surrounding rocks. The liquid-release tests and air-injection tests provide an evaluation of in situ fracture flow and the competing processes of matrix imbibition. Only the findings from testing and data not covered in the ''Seepage Calibration Model and Seepage Testing Data'' are analyzed in detail in the AMR.

The giant honey bee Apis dorsata has a vast distribution in Asia, including in the Indonesian archipelagos, whereas A. d. binghami is endemic to Sulawesi Island. This research aimed to analyze the variations of landmarks in wing venation of A. dorsata from Sumatra, Belitung, Java, Sumbawa, Moluccas islands, and A. d. binghami in Sulawesi, based on geometric morphometric analysis. Nineteen landmarks from 200 wing venations were analyzed using Thin Plate Spline software. Our study found landmarks 16 and 17, known as Cubital Index in traditional morphometrics, contributed to the wing shape of A. dorsata and A. d. binghami Among all samples, these two landmarks show high displacement in the wing shape of A. d. binghami in Sulawesi and A. dorsata in the Moluccas. On the contrary, we found that the Sumatra, Belitung, and Java Apis dorsata revealed low displacement in the deformation grid; resulting in their shapes being more similar to the reference landmark. The variations of wing shape separate A. d. binghami from Sulawesi and Sumbawa in the Principle Component Analysis and agreement with the Neighbor-joining tree. Therefore, the geometric morphometric based on landmarks of wing venation is a powerful tool to discriminate the subspecies level of A. dorsata.

The so-called Caspian Locust is morphologically so closely related to Gleditsia horrida (Thunb.) Miq. from Japan that it has been considered by C. K. Schneider merely as a variety of the latter. Legumes of both taxa were compared without finding differences. It is pointed out that laterally setose legumes as that figured recently by Dudik, do not occur in G. horrida. The area of distribution, both present and past, of relict laurel-type forests is discussed with the conclusion that G. caspia Desf. is best regarded as a subspecies of G. horrida; three necessary new combinations are made in an Appendix.


We study the clustering of SZ-selected galaxy clusters on a past light-cone, particularly paying attention to the possibility of constraining properties of dark energy. The prospects of detecting baryonic features in the cluster power spectrum for a wide and shallow survey like PLANCK, and for an SPT-like narrow and deep survey are discussed. It is demonstrated that these future blank sky SZ surveys will have the capability to improve over the recently announced detection of baryonic oscillations based on the SDSS Luminous Red Galaxy (LRG) sample. We carry out parameter estimation using a Fisher matrix approach taking into account the anisotropic nature of the power spectrum due to redshift space and cosmological distortions. The clustering signal which is not too sensitive to systematic uncertainties serves as a valuable piece of information that in combination with other sources of data helps in breaking degeneracies between the cosmological parameters.


In this Paper. we propose a recognition method of machine printed characters based on the combination of recognition units using multiple neural networks. In our recognition method, the input character is classified into one of 7 character types among which the first 6 types are for Hangul character and the last type is for non-Hangul characters. Hangul characters are recognized by several MLP (multilayer perceptron) neural networks through two stages. In the first stage, we divide Hangul character image into two or three recognition units (HRU : Hangul recognition unit) according to the combination fashion of graphemes. Each recognition unit composed of one or two graphemes is recognized by an MLP neural network with an input feature vector of pixel direction angles. In the second stage, the recognition aspect features of the HRU MLP recognizers in the first stage are extracted and forwarded to a subsequent MLP by which final recognition result is obtained. For the recognition of non-Hangul characters, a single MLP is employed. The recognition experiments had been performed on the character image database collected from 50,000 real letter envelope images. The experimental results have demonstrated the superiority of the proposed method.

Mixtures of soy protein (SP) and gum arabic (GA) formed an electrostatic complex in a relatively narrow pH range at very low ionic strength. The conditions under which the complexes could be formed were determined using turbidimetric measurements first. In salt-free condition and 1:1 SP/GA mixture, critical pH values with the formation of soluble (pHc = 4.40), insoluble (pHφ1 = 3.55), and maximum (pHopt = 3.15) complexes were observed. As SP/GA ratios increased from 1:4 to 8:1, critical pH values shifted toward higher pH. Charge densities (ZN) for SP and GA were calculated from electrophoretic mobility using soft particle analysis theory. Results showed that a 1:1 charge ratio at pHφ1 was found at any SP/GA ratio, indicating that charge compensation was fulfilled for SP/GA insoluble complex formation. A SP–GA–water ternary phase diagram was built at pH 4.0. The influence of the total biopolymer concentration (0–10% w/w) and SP/GA ratio was represented in the phase diagram. At a total concentration of 0.10...


The aim of this paper is to introduce and study a new class (l ∞ (X, Y, Φ, ξ, w , L), H U ) of locally convex space Y- valued functions using Orlicz function Φ as a generalization of some of the well known sequence spaces and function spaces. Besides the investigation pertaining to the linear topological structures of the class (l ∞ (X, Y, Φ, ξ, w , L), H U ) when topologized it with suitable natural paranorm , our primarily interest is to explore the conditions pertaining the containment relation of the class l ∞ (X, Y, Φ , ξ, w) in terms of different ξ and w so that such a class of functions is contained in or equal to another class of similar nature.


We are currently in an era full of information and communication technology. One of the communication media used is Twitter. Twitter is a microblogging service that is used by its users to express their thoughts on a topic called a tweet. Tweets that are posted can be either positive tweets or negative tweets. One of the topics that is currently being discussed by Twitter users is Anies Baswedan as a 2024 Indonesian Presidential Candidate. Many people have tweeted this but it is not known how many users support or reject Anies Baswedan to run as a 2024 Indonesian presidential candidate. To assist the analysis, use the method clustering namely algorithm (Density-Based Spatial Clustering of Application with Noise). DBSCAN has the advantage of being able to detect data that is not included in a cluster and will be considered noise. This can improve the accuracy of the grouping because the data in the cluster will be cleaner. The TF-IDF Vectorizer is used to make it easier for programs to manage data because it can turn sentences into vectors that can be processed by the algorithm. To determine the evaluation of the program, the silhouette score method will be used. The results of calculating the silhouette score show a value of 0.29 with the formation of 3 clusters. Then an analysis is carried out based on the top words from each cluster and it can be identified that cluster 0 has a positive category supporting Anies Baswedan to run for the 2024 Presidential Candidate and cluster 1 has a negative category that does not support Anies Baswedan not advancing for the 2024 Presidential Candidate.

Available in abstract form only. Full text of publication follows: Now beryllium is widely used as neutron reflector and moderator of research nuclear reactors. For example, the SM and MIR research reactors are operated in the RIAR, Dimitrovgrad, Russia. In the SM reactor neutron reflector blocks which are placed on perimeter of core and neutron trap blocks (moderator) which are placed in the central position of core were made from beryllium. In the MIR reactor the laying of core is consist of beryllium hexagonal blocks. During operation in a reactor beryllium is exposed to high dose neutron irradiation therefore high induced radioactivity arises in a material. After unloading from a reactor irradiated beryllium blocks are subject to storage in storage facilities for high level radioactive solid waste. Volume of storage facilities is limited. At present amount of irradiated beryllium as massive blocks which have fulfilled in a reactor is great enough, and it continues to increase. These circumstances lead to necessity of carrying out of investigations to basement of decontamination processes, disposal and storage of radioactive beryllium waste. Now useful storage capacities are not used in the best way since the irradiated blocks located there have large dimensions and complicatedmore » geometrical form. As a result optimization of radioactive beryllium waste disposal process will include transformation of massive blocks to more compact form with low level of radioactivity. It is considered now to use of beryllium as a material for fusion reactor. In the DEMO reactor beryllium will be used as neutron multiplier for blanket. In this case amount of irradiated beryllium will be more significant, and problems of its storage will be analogous. (authors)« less

This document describes the fundamental criteria in the design of a Cartesian table automated with three axes XYZ with an interchangeable head to work with plasma cutting and oxyfuel, as the selection of the processes implemented for its construction. For this the table splits into four fundamental parts; X axis, Y axis, Z axis and control system. It is begun by a conceptual design in which the basic dimensions of the table are defined and a counterfoil of selection of components is realized, then in a detailed design to determine the dimensions and exact characteristics of every component. Later, the systems and subsystems of the table, that generate significant effects on the structural elements, were validated by means of charges simulations. The elements selection was based on the esthetics, availability of materials and processes of manufacture of easy access on the market that were offering high quality to low cost. In order to conclude, with the detailed design in this document, it is possible to construct a table CNC with high precision and low cost.

With the introduction of solid state light sources, the variety in emission spectra is almost unlimited. However, the set of standardized parameters to characterize a white LED light source, such as correlated color temperature (CCT) and CIE general color rendering index (Ra), is known to be limited and insufficient for describing perceived differences between light sources. Several characterization methods have been proposed over the past decades, but their contribution to perceived color quality has not always been validated. To gain more insight in the relevant characteristics of the emission spectra for specific applications, we have conducted a perception experiment to rate the attractiveness of three sets of objects, including fresh food, packaging materials and skin tones. The objects were illuminated with seven different combinations of Red, Green, Blue, Amber and White LEDs, all with the same CCT and illumination level, but with differences in Ra and color saturation. The results show that, in general, object attractiveness does not correlate well with Ra, but shows a positive correlation with saturation increase for two out of three applications. There is no clear relation between saturation and skin tone attractiveness, partly due to differences in preference between males and females. A relative gamut area index (Ga) represents the average change in saturation and a complementary color vector graphic shows the direction and magnitude of chromatic differences for the eight CIE-1974 test-color samples. Together with the CIE general color rendering index (Ra) they provide useful information for designing and optimizing application specific emission spectra.

With frequent food safety incidents, it becomes urgent and important to design an intuitively quantitative trust model to describe the trustworthiness of foods delivered in supply chains. However, current existing models are usually too subjective, because they heavily depend on experts' experiences to model the trust and set relevant parameters. Fortunately, the Internet of Agricultural Things may offer a big volume of business data, including product information and delivery information etc., via its pervasive sensing. These data motivate us to design a data driven quantitative model to evaluate the trust of sensed products in supply chains. The proposed trust model leverages a Bayesian network, where almost all parameters are set by the data rather than experts' experiences, to evaluate the trust value of a target product. Finally, a case of pork product is used to show the effectiveness of our trust model. Based on the comparison with other models, our model is promising to reduce the subjectivity and time-delay of the trust evaluation.


A genetic algorithm is used for the topology design of feed-forward neural networks. The generated neural network topology populations are then trained to approximate non-linear relationships of multiple variables. A specifically designed fitness function using the epistemological principle of dimensional homogeneity is used for the evaluation of the individual neural network generations and for the selection of the best generalizing neural networks topologies. A general theory for the topology design and the explanation of the correct generalization capability of non-linear feed-forward neural networks is developed, mathematically proved and explained using simulation results.
