Two of the oldest known classical integrable systems are: (i) n-decoupled harmonic oscillators, constrained to the surface of the n-sphere (i.e., the classical C. Neumann system), and (ii) geodesic flow on an n-axial ellipsoid. We integrate both these systems at the quantum level. That is, in both cases we construct n−1 pairwise-commuting partial differential operators which, in turn, commute with the respective quantum Hamiltonians. Moreover, the joint eigenvalues of the commuting partial differential operators appear to be encoded linearly as parameters in an n-parameter eigenvalue equation given by a second-order complex ordinary differential equation with automorphic boundary conditions. We then focus on the particular case of two degrees of freedom (i.e., R3). Via the microlocal wave-averaging ansatz combined with explicit WKB constructions, we give a spectral analysis (both classical and semiclassical) of the above systems, and subsequently exhibit connections between the various spectral asymptotics. In the course of this analysis, we show that the above two systems are intimately related to yet another quantum integrable system, the reduced quantum asymmetric rigid body in a vacuum.


We revisit the domain wall problem for QCD axion models with more than one quark charged under the Peccei-Quinn symmetry. Symmetry breaking during or after inflation results in the formation of a domain wall network which would cause cosmic catastrophe if it comes to dominate the Universe. The network may be made unstable by invoking a "tilt" in the axion potential due to Planck scale suppressed non-renormalisable operators. Alternatively the random walk of the axion field during inflation can generate a "bias" favouring one of the degenerate vacua, but we find that this mechanism is in practice irrelevant. Consideration of the axion abundance generated by the decay of the wall network then requires the Peccei-Quinn scale to be rather low - thus e.g. ruling out the DFSZ axion with mass below \sim∼ 11 meV, where most experimental searches are in fact focused.


Using detector tube,the testing of formaldehyde concentration is simple and rapid,and can detect degradation of formaldehyde of photocatalytic textiles effectively.Generally,the degradation of formaldehyde of photocatalytic textiles is the most obvious during the first 1-hour reaction.As the reaction time increases,the degree of degradation decreases,and remains stable after 4 h.


This article presents a quantitative sociological study of the expansion of the worship of Isis in Greco-Roman antiquity focusing on the role of large urban centres. Receptivity to the cult is measured for a data set of 44 cities based on the presence or absence of archaeological remains. Statistical correlations between the spread of the Isis cult and city size, distance from Alexandria and distance from Rome (a secondary centre of the cult's expansion) support the thesis that distance from cultic centres was a significant factor in the spread of Isiac worship. The paper concludes with a number of suggestions for further research.


Recently, Transformer has achieved state-of-the-art performance in neural machine translation. However, the number of parameters in Transformer is so large that it needs to be compressed before deployed and executed on resource-restricted devices. In this paper, we propose a compressed version of Transformer called Compressed-Transformer. We introduce two techniques, factorizing parameters and block reduction, to compress Transformer model. Consequently, the number of parameters can be reduced by more than 50%. We exploit a stage-wise distillation strategy with the temperature dynamically adjusted in knowledge distillation practice to transfer knowledge from base Transformer (teacher) to Compressed-Transformer (student). A Chinese-to-English (Zh~En) dataset of United Nations Parallel Corpus and a German-to-English (De~En) dataset of Multi30K are used, and the experimental results show that our compressed model achieves BLEU score only slightly lower than uncompressed teacher model. Specially, when the number of parameters is reduced by 59.3%, the student model can achieve BLEU score of 40.69, only 1.64 lower than that of the teacher model, and the inference speed is improved by 17% on Zh~En dataset. The experiments on De~En dataset also achieve the similar results.


In a device for discharging tire sealing agent from a container which can be connected to a pressure source and to a tire valve, a check valve (5, 5.1) is provided in the connection to the pressure source and/or in the connection to the tire valve.


China's rise as a major power has generated wide-ranging discussions and debates among scholars, analysts and in the corridors of power in major global and regional capitals. On the one hand, there are great expectations that a more prosperous, influential, and engaging China can and should make positive contributions to solving major issues such as economic recovery, climate change, and nuclear nonproliferation. On the other hand, there are also growing concerns about a more confident, assertive and indeed an insecure China that could pose serious challenges to international and regional order.


Cancer remains one of the diseases with increasing number of sufferers, but research on compounds that act as anti-cancer is also ongoing. Terpenoids have been known as a compound that can inhibit the proliferation of cancer cells. One of the medical plants that produce terpenoids is Jarak cina ( Jatropha multifida Linn . ). Therefore, the possibility of Jarak cina ( Jatropha multifida Linn. ) to have an cytotoxic activity on cancer cell proliferation is reasonably high. This study was conducted to determine the cytotoxic activity of Jarak cina ( Jatropha multifida Linn.) bark extracts against cancer cell MCF-7. Jarak cina bark was extracted using the multilevel soxhlet extraction method with n-hexane, ethyl acetate, and ethanol as the solvents. All the three extracts were then tested against MCF-7 cancer cells using MTT (3-(4,5- dimethylthiazol -2- yl ) - 2,5- diphenyltetrazolium bromide ) method. Data analysis was performed for IC 50 (ppm) parameter. The results showed that the IC 50 of n-hexane extract was 313.21 ppm, while the ethyl acetate extract reached 258.38 ppm of IC 50 , and the IC 50 of ethanol extract was 418.51 ppm. The highest potential of cytotoxicity was found in the ethyl acetate extract, so further testing would be required to optimize the proliferation inhibitory activity.


The purpose of this study was to examine how nursing personnel experience their work at long-term geriatric institutions. The study was conducted at five community hospitals in a province in southern Finland. The data was collected using a questionnaire. The sample consisted of 248 nurses on 13 wards, and the response rate was 85 per cent (N=210). Data was analysed by conducting cross tabulations and one way analysis of variance. The results showed that the nurses experienced the physical, psychological and work community loads of their work as quite small. However, a large part of the respondents experienced their work at longterm geriatric institutions as meaningless and felt a lack of social respect for their work. The oldest of the respondents (aged 46 or over) and those who had worked in the nursing field for over 10 years expressed their preferential to work especially at the geriatric institutions. The enrolled and licensed nurses experienced the greatest physical work load.


Over the past few decades, ubiquitous sensors and systems have been an integral part of humans' everyday life. They augment human capabilities and provide personalized experiences across diverse contexts such as healthcare, education, and transportation. However, the widespread adoption of ubiquitous computing has also brought forth concerns regarding fairness and equitable treatment. As these systems can make automated decisions that impact individuals, it is essential to ensure that they do not perpetuate biases or discriminate against specific groups. While fairness in ubiquitous computing has been an acknowledged concern since the 1990s, it remains understudied within the field. To bridge this gap, we propose a framework that incorporates fairness considerations into system design, including prioritizing stakeholder perspectives, inclusive data collection, fairness-aware algorithms, appropriate evaluation criteria, enhancing human engagement while addressing privacy concerns, and interactive improvement and regular monitoring. Our framework aims to guide the development of fair and unbiased ubiquitous computing systems, ensuring equal treatment and positive societal impact.


ii Abstract A generalization to the BTK theory is developed based on the fact that the quasiparticle lifetime is finite as a result of the damping caused by the interactions. For this purpose, appropriate self-energy expressions and wave functions are inserted into the strong coupling version of the Bogoliubov equations and subsequently, the coherence factors are computed. By applying the suitable boundary conditions to the case of a normal-superconducting interface, the probability current densities for the Andreev reflection, the normal reflection, the transmission without branch crossing and the transmission with branch crossing are determined. Accordingly the electric current and the differential conductance curves are calculated numerically for Nb, Pb, and Pb0.9Bi0.1 alloy. The generalization of the BTK theory by including the phenomenological damping parameter Γ is critically examined. The observed differences between our approach and the phenomenological approach are investigated by the numerical analysis.A generalization to the BTK theory is developed based on the fact that the quasiparticle lifetime is finite as a result of the damping caused by the interactions.

The paper proposes a method for predicting the workload of virtual machines in the cloud infrastructure. Reconstruction probabilities of variational autoencoders were used to provide the prediction. Reconstruction probability is a probability criterion that considers the variability in the distribution of variables. In the proposed approach, the values of the reconstruction probabilities of the variational autoencoder show the workload level of the virtual machines. The results of the experiments showed that variational autoencoders gave better results in predicting the workload of virtual machines compared to simple deep neural networks. The generative characteristics of the variational autoencoders determine the workload level by the data reconstruction.


This project is based on the implementation of different techniques of control, to control a robotic arm with elastic joints. The main objective of this project is the design of optimal control with which, we pretend to operate the dynamic system at the lowest cost. Three modalities of the quadratic linear regulator have been tested: the classic, with trajectory tracking and the iterative. Previously the dynamic model has been obtained through the Lagrange-Euler equations that require the potential and kinetic energies of the different links. Then, the model has been linearized to move to the state space, which is the recommended way to manage and control multivariate processes. For the tests of the control, on the one hand, it has been tested and simulated with Matlab and on the other hand, it has been tested in the real plant. For the case of the real plant, a microcontroller has been used and it represents the control device. That involves interaction with sensors and actuators and the need to develop a software that performs all the tasks of interpreting information to determine and obtain the control algorithm that brings the system to the desired state. Also, homing has been implemented and security measures like controlled stop.


This empirical research was conducted based on qualitative transcendental phenomenological approach. The in-depth interviews were conducted with 15 procurement professionals located in Malaysia. The emerging technologies related to procurement include electronic procurement, Internet of Things, big data analytics, artificial intelligence, and 3D printing. These emerging technologies potentially enabling procurement professionals to be relevant, effective and efficient in their working activities. However, procurement professionals experience many challenges of adopting these emerging procurement technologies. This research revealed six challenges of emerging technologies as experienced by procurement managers. First, talent management is very crucial for adoption of emerging technologies. Second, difficulty to prioritize and integrate different types of emerging technologies. Third, lack of electronic data interchange to achieve full implementation of e-procurement. Fourth, data security and data quality of emerging technologies. Fifth, top management and headquarters are required for adoption of emerging technologies. Sixth, lack of financial justification to adopt emerging technologies.


In the past ten years, several hundred studies have been conducted to document the plight of uninsured Americans. The evidence from these studies contradicts the notion that a lack of insurance is merely an inconvenience as is often supposed by many Americans. These studies confirm that there are real consequences of being uninsured. The American College of Physicians-American Society of Internal Medicine (ACP-ASIM), representing 115,000 physicians of internal medicine and medical students, presents the significant data it has collected in "No Health Insurance? It's Enough to Make You Sick."


The bending of through-cracked ferromagnetic plates in a static magnetic field is investigated to show the effect of induced magnetization. A simple experimental technique employing strain gages is used to determine the magnetic moment intensity factor. The theoretical results agree very well with the experimental data. The scattering of time harmonic flexural waves by a through crack in an infinite plate under a uniform magnetic field is also studied.

Private-equity investors are increasingly purchasing chemical firms as a viable means for generating profits. As the chemical industry continues to cope with a downward business cycle in 1999, industry experts say the opportunities for private-equity investors will increase as more chemical firms, strapped for cash, sell off nonstrategic businesses. Private-equity firms manage pools of capital, typically organized as a limited partnership, that invest in well-established companies, representing opportunity for a high rate of return. Their investments generally include acquisitions or recapitalizations of public and private companies. Private-equity investments are different from venture-capital investments, which typically provide seed or earlystage money to start-up companies. "If you talk venture capital, people think start-up businesses," says Stuart A. Auerbach, a general partner with privateequity firm Ampersand Ventures, Wellesley, Mass. "In the chemical industry, that's the smaller piece of the equ...


Paper reflects on the features of the formation of normative monetary evaluation of land in settlements (hereinafter abbreviated as NME). The nature of the formation of the constituent of the regional differential land rent coefficient Km1 – the coefficient characterizing population size (Km1p). Ukraine settlements classifications scheme suggested, which gives a comprehensive imagination of urban and rural settlements hierarchy in the general resettlement system of the state. Influence of indicators of a population size of different categories on a residence place - the available and permanent population on NME value is analyzed. The desirability of making changes to the Order of normative monetary evaluation of land in settlements has been justified. Specifically, it is proposed to point out that the calculation of NME is based on the account of the constant population size at the beginning of the year for which normative monetary evaluation of land is being performed. Keywords: land management, urban development, normative monetary evaluation of land in settlements (NME), population.


This paper develops pseudo-differential algebraic functions which unequivocally incorporate most typical conventional systems and problems of the parabolic limit value discerned forms. Therefore, to achieve this, this paper develops a pseudo-differential parabolic operator's theory in anisotropic spaces. A significant calculus is developed for various classical symbols which are defined universally by R ∗ R. A periodical procedure regarding the symbolic calculus in a cylinder such that T ∗ R is developed. The Garding's inequality is exhibited for its appropriate operators as well as definite estimates for the vital criterion of the Sobolev anisotropic spaces. Introduction This paper is motivated by the behavior of various boundary or limit value element sequence from the heat equation. Pseudo-differential operator analysis hasbeenhighly appreciatedfor the elliptical limit value problems. However, researchers have not fully exploited the pseudo-differential operators formed by the reduction of the limit value of the parabolic functions. Therefore, the Garding's inequality and the estimates of the vital criterion in Sobolev anisotropic spaces for limitation techniques are yet to be researched. Only several parts of the rationale of accustomed pseudo-differential parabolic operands exist. For instance, Piriou (1970) came up with a rationale for parabolic limit value problems as well as pseudo-differential parabolic operands as represented symbolically through the use of expanded functions in quasi-homogeneous functions. Earlier work by Hunt and Piriou (1969) prepared the results of the expanded quasi-homogeneous functions which extended to the pseudo-differential operator's calculus. This study develops a given pseudo-differential operator's calculus containing symbolic anisotropies having the Piriou's limit integral operand to express the parabolic limit value problems. This study uses a class of operands which is well explained in Beals' (1975) study on the pseudo-differential operators general calculus. In his work, Beals clearly shows the relationship between L and continuity of the Sobolev spaces applying various theorems. However, this study will opt to apply the fundamental method as elaborated by Hormander (2013). This fundamental method refrains from the theory of perfectly sustained operators and uses the calculus of symbols which are universally defined. It is made fundamental by the fact of obtaining the continuity of L through basic properties of infirm unique integral operands. The concept used in this study presents essential tools for administering periodization to satisfy the need for coverage of cylindrical realm. The Garding's inequality also is proved as well as the distinct criterion measures. The results of Noon (1988) and Costabel (1990) are achieved for the elementary parabolic limit integral operand.


We applied digital color management by holoprinter, which produces full-color full-parallax hologram. The color reproducibility was tested by printing color chart hologram, and the CIELAB ΔE is fairly small.


The steady state photocarrier grating technique has emerged as an important technique for measurement of the diffusion length in amorphous silicon. In this communication we show that morphological inhomogeneities lead to an overestimation of the magnitude of the diffusion length. The magnitude of this error cannot be easily estimated.


Immune rejection after corneal penetrating keratoplasty is still one of the main reasons leading failure of the surgery,especially in high-risk cases,in whom the rejection ratio can be as high as 50%.Glucocorticoid is still the first-line drug for the prevention and treatment of corneal graft rejection,and topical application of which is the main way of administration,but long-term using of which should be paid more attention to avoiding the side effects.Cyclosporin A(CsA) eye drops in combination with glucocorticoid can be better to prevent immune rejection episodes and reduce the side effects of steroid.Topical tacrolimus application also showes a good result.


Generating student involvement and enthusiasm in IEEE activities at both local and regional levels is always a challenge. Over a number of years, we in Region 3 have developed a regional student activities program that has become very effective at doing just that. SOUTHEASTCON, our annual regional technical conference, brings practicing professionals and students together in a social and professional setting.


But we have also modified the text to stress the role of structural geology and geophysics. Specifically, we added a paragraph at the end of the section on "geology and geophysics" For the purpose of subsequent hydrogeological analyses, it is important to highlight that (1) the above discussion is the result of a structural geological interpretation of 3D seismics (specifically, direct seismic inversion was often modified after discussions with structural geologists, who pointed to inversion inconsistencies. Therefore, it can be stated that seismic inversion was "structural geologically biased"); (2) some water conducting faults (specifically 474, and 285), were identified during seismic inversion, but had not been mapped because they are located in an area covered by meadows; and (3) geophysics also helped to identify highly fractured zones (e.g., fractured granitic units, fractured belts around the dykes and South faults), which provided hydraulic connectivity.

Ponggok community awareness of the importance of social change makes people decide to accept and adopt innovation BUMDES Tirta Mandiri.


Multi-pin joints are commonly used in engineering due to their high loading capacity. However, affected by coupling relationships between pin load and bypass load, the evaluation of stress state is difficult for composite multi-pin joints. An analytical method is proposed in this paper to calculate stress distribution of these joints under tensile load. Stress functions in this method are created considering the pin load and bypass load, according to a geometry division of the whole plate. Superposition relationships are built for each section type with an influence coefficient of bypass load. Stress components could be obtained by calculation of stress functions when material properties, geometry dimension and load are known. Experiments and finite element method are employed to verify the validation of proposed method. Results show that pin position affects stress state, and mainly embodies in σx. The first pin always gets the highest stress level, while for the other pins the stress is quite similar. Increase pin number will decrease stress level but the effect is relatively small for the first pin.


The effects of some coumarins (coumarin, 7-hydroxycoumarin, scopoletin and esculetin) were investigated on pumpkin (Cucurbita maxima Duch.) seedlings and on pumpkin glutathione S-transferases (GSTs). Coumarin and esculetin suppressed the growth of seedlings, especially the elongation of roots as well as hypocotyls. Among the compounds tested, only esculetin inhibited the activity of a particular pumpkin GST by 50%, CmGSTU3 toward 1-chloro-2, 4dinitrobenzene (CDNB) and at a concentration of 22 μM. Both ethylacetae (EtOAc) and water fractions in pumpkin seedlings and different organs of one-month-old pumpkin plants contained esculetin or similar hydrophobic fluorescent substances as well as hydrophilic substances, which showed different degrees of inhibitory effects on CmGSTU3 activity.


When researchers seek to study the influence on traffic risk of factors related to mobility, the economy and road safety policies, they tend to use models that are based on the exploitation either of cross sections of a panel of regions or sites, or of chronological series (annual, monthly or daily). This research is directed at the second type of model, which is useful for: (1) evaluating the effects of road safety measures at a national level that are becoming increasingly complex; this complexity comes from spatial and temporal variations in populations affected by the measures (points system for driving licenses, technical inspections of vehicles, and so on); and (2) basing the interpretation of medium and long-term traffic risk on those of mobility and the economy. More specifically, the objective of the research was to develop an econometric model of traffic risk know as Traffic, Accident and Gravity (TAG), starting from the Road Demand, Accident. And Gravity) DRAG model conceived in Quebec, which remains a world-class reference. The structure of this model was adapted to the specific conditions of traffic risk in France and added to it by building in speed as an indicator of driver behavior. This adaptation consists, for example, of introducing variables relating to motorized two-wheelers, or to the stock of small cars, or to traffic shares according to road network categories, which are peculiar to French conditions. The addition of a fourth dimension related to behavioral risk is an innovation in this kind of model, made possible by the availability of a long series on speeds driven, as measured by surveys on interurban roads. Risk analysis is classically based on the triad: Exposure; Accidents; and Casualties, using risk indicators such as accident rates per vehicle-kilometer or the severity rate in terms of the numbers killed per injury accident.


This study aimed to screen high-performance flocculant-producing bacteria for flocculating suspended matter in wheat distillery wastewater. After the preliminary and secondary screening, a high-performance flocculant-producing bacteria strain was screened from the activated sludge of wheat distillery wastewater. Single factor and orthogonal experiments were used to optimize the culture and flocculent conditions for the flocculant-producing bacteria. A superior strain of Klebsiella M1 was screened and identified by 16S rDNA. The initial flocculating degree was up to 72%. Based on single-factor tests, the optimum flocculent conditions were a resting time of 30 min, 8%(v/v) culture medium dosage, and 3%(v/v) CaCl2. The optimum culture conditions were an incubation temperature of 30 °C for 48 h at pH 4.5 and rotation speed of 150 rpm. Under the optimum conditions, the flocculating degree was up to 82%. The best fermentation medium components were 15 g/L glucose, 2 g/L peptone, 1 g/L KH2PO4, and 2.5 g/L K2HPO4. A high flocculating degree was also achieved with the low-cost medium. The Klebsiella M1 bacteria strain can be used as a good bioflocculant produced bacteria for wheat distillery wastewater.

Abstract Introduction. Extended-spectrum β-lactamase (ESβL)-producing Klebsiella pneumoniae is currently one of the most common causes of nosocomial infections worldwide. The study aimed to characterize antibiotic resistance profile, the prevalence of selected genes encoding ESβLs, virulence, and the genetic relationship in 139 K. pneumoniae isolates identified in John Paul II Specialist Hospital in Southern Poland, collected in 2016. Materials/Methods. Bacterial identification and the preliminary antibiotic susceptibilities was performed using the VI-TEK® 2 Compact automated system. Genes encoding ESβLs were amplified by CTX-Mplex PCR and PCR reactions. The presence of nine genes encoding virulence factors was studied by multiplex PCR. Clonality was investigated by PFGE after digestion with SpeI endonuclease. Results. K. pneumoniae were mostly recovered from the respiratory tract (40.3%), urine (32.4%), wound swabs (19.4%) and blood (5%). In summary, 82.7% of strains were classified as multidrug resistant (MDR). All isolates were confirmed as ESβL producers and carried blaCTX-M-type (85.6%), blaSHV (82%), blaTEM (77.7%), blaCTX-M-9 (75.6%) and blaCTX-M-1 (1.4%) in various combinations. Moreover, triple bla genes were observed in 72% of isolates. The most common virulence-as-sociated genes found among the isolates were entB (91.4%), ybtS (55.4%), iutA (55.4%), magA (53.2%), kfu (14.4%), K2 (11.5%), mrkD (10.1%), rmpA (7.9%) and allS (5%). The PFGE analysis identified 4 major clusters (A–D) comprising 61% of the entire collection. Conclusions. Our results indicate that the presence of a wide variety of MDR K. pneumoniae harbor ESβLs and virulence genes. Studies on molecular epidemiology of ESβL-producing K. pneumoniae isolates are needed, particularly for epidemiological surveillance in the hospital environment.


The 6-stand hot strip finishing mill planned by Algoma Steel would impose frequent swings on the utility tie line of 41 MW and 41 Mvar. Each swing would occur over a 10-second interval. To avoid these swings on the utility tie, a steam power plant rated 25 MW continuous with features permitting peak cyclic loading to 41 MW and 41 Mvar was installed. Special megawatt and megavar controls vary the power plant output to match the varying input to the strip mill. High-speed recordings of plant performance during strip mill operation are included. This is believed to be one of the few, if not the only, steam power plants operating in this manner.


A one-dimensional quasi-equilibrium MHD code has been used to study the effect of heat transport in belt-pinch-like reversed-field configurations compressed by an imploding cylindrical conducting liner. The code incorporates classical and anomalous transport coefficients, including drift ion cyclotron and lower hybrid instabilities with fluctuation amplitudes limited by shear and finite-beta stabilization. For a reactor-size imploding-liner configuration, heat conduction produces flat-topped temperature profiles and peaked densities. Scaling the reactor size down by a factor of five leads to a considerable increase of anomalous heat losses. A high-field, low-density buffer region near the wall is effective as a heat insulator, provided the field is sufficiently sheared there.

We model the cosmic distributions in space and time of the formation sites of the first stars that may be the progenitors of supermassive black holes (SMBHs). Pop III.1 stars are defined to form in dark matter minihalos (i.e., with masses $\sim10^6\:M_\odot$) that are isolated from neighboring astrophysical sources by a given isolation distance, $d_{\rm iso}$. We assume these sources are the seeds for the cosmic population of SMBHs, based on a model of protostellar support by dark matter annihilation heating that allows these objects to accrete most of the baryonic content of their minihalos, i.e., $\gtrsim10^5\:M_\odot$. Exploring a range of $d_{\rm iso}$ from $10$ to $100 \ \rm{kpc}$ (proper distances), we predict the evolution with redshift of the number density of these Pop III.1 sources and their SMBH remnants. In the context of this model, the local, $z=0$ density of SMBHs constrains $d_{\rm iso}\lesssim100\ \rm{kpc}$ (i.e., a comoving distance of $3 \ \rm{Mpc}$ at $z\simeq30$). In our simulated ($40.96 \ h^{-1}\rm{Mpc}$)$^3$ comoving volume, Pop III.1 stars start forming just after $z=40$. Their formation is largely complete by $z\simeq25$ to $20$ for $d_{\rm{iso}}=100$ to $50 \ \rm{kpc}$. We follow the evolution of these sources down to $z=10$, by which point the SMBHs are expected to reside in halos with $\gtrsim10^8\:M_\odot$. Over this period, there is relatively limited merging of SMBHs for these values of $d_{\rm iso}$. We also predict the clustering properties of the SMBHs in this model at $z=10$: the effective feedback suppression of neighboring sources in the $d_{\rm iso}=100\ \rm{kpc}$ model leads to a relatively flat angular correlation function. The general results of this work will be used for population synthesis models of active galactic nuclei, which can be compared with future high redshift observations.


Animal waste is a valuable resource, which, when managed properly, can reduce the need for commercial fertilizer. It can also improve the soil water holding capacity and tilth. Similarly, as a newly recognized water resource, nutrient-rich reclaimed wastewater supplies not only water, but also plant nutrients (especially nitrogen and phosphorus) that can benefit agricultural production. When animal waste or reclaimed wastewater is used for land applications or agricultural irrigation, the major concern is the possible spreading of pathogenic organisms in the soil and the possibility of groundwater contamination once the pathogenic organisms pass through the vadose zone and reach the groundwater table. Proper chemical treatment is required either to kill the pathogens or to enhance the retention of the pathogens in the subsurface soil to protect the groundwater from being contaminated. In this study, we have investigated the impact of lipopolysaccharide extraction on bacterial retention in a porous medium (silica sand) using column experiments. Three gram-negative bacterial strains of Escherichia coli, Pseudomonas fluorescens and Pseudomonas aeruginosa were used as model bacterial strains and their transport was described by the two-region (equilibrium/kinetic) model. After lipopolysaccharide extraction, all these three strains showed greater retention in the porous medium. Increase in retention after the lipopolysaccharide extraction was most pronounced for Pseudomonas fluorescens and least for E. coli. Bacterial retention in the porous medium was correlated with their interactions with the porous medium.


In the present research we aim to verify a newly developed on-line path-planning algorithm that directs a non-holonomic robot to a goal while avoiding obstacles in an uncertain 3-d world easily and reliably. The developed robot runs on two wheels and is equipped with a visual sensor (CCD camera) with a restricted view field, Please clarify, a gyrocompass and a means of measuring and recording wheel running distance to recognize its position. Furthermore, as this robot is controlled by a parallel processor called a transputer, it can perform four types of distributed processing simultaneously: autonomous position inference, image measurement processing, running control, and running algorithm monitoring. In experiments, the robot reached its goal without coming into contact with any obstacles. As a result, it was verified that this developed sensor-based path-planning algorithm was effective for this nonholonomic mobile robot.

A method is presented to compare the accuracy and computational cost of explicit one-way extrapolation operators as used in seismic imaging. For a given model, accuracy is measured in terms of lateral positioning error, and cost is calculated relative to the cost of the spatial fast Fourier transform. The result is a planned imaging scheme that achieves the greatest accuracy with respect to the velocity model for a fixed cost. To demonstrate, we use a 2D section of the EAGE/SEG salt model and assemble a suite of the most common operators. The data are imaged using each operator individually, and the results are compared to the result from the plan-based algorithm. The planned image is shown to return improved accuracy for no additional cost.

Due to the rapid development of roller-compacted concrete technique in dam construction research interest in stepped spillway hydraulics increased in recent years. Because of the strong turbulence enhanced by the step-induced macro-roughness the flow velocity is lower than on comparable smooth spillways. By consequence, a higher flow resistance and hence, a higher energy dissipation must be noted as a main characteristic. Earlier investigations indicate that the energy dissipation potential is only slightly influenced by a change of slope on embankment stepped spillways with moderate slopes between 18.4° and 26.6° [2]. In order to quantify the general effect of the macroroughness a comparative study of self-aerated flow on stepped spillways and smooth invert chutes, respectively, with a slope of 26.6° has been carried out.


Examples are given of alteration of blue areas to green on medieval austrian murals dating from the 13th to the 15th century. In one case azurite had altered to atacamite and paratacamite. In another case the blue pigment, smalt, appeared green because the protein-rich medium (possibly casein) had become yellow. Identifications were made by microscopical analysis and by x-ray diffraction.


Osteosarcoma (OSA), the most common malignant bone tumor in dogs and children, exhibits a similar clinical presentation and molecular biology in both species. Unfortunately, 30–40% of children and 90% of dogs still die of disease despite aggressive therapy. The purpose of this study was to test the biologic activity of a novel heat shock protein 90 (HSP90) inhibitor, STA‐1474, against OSA. Canine and human OSA cell lines and normal canine osteoblasts were treated with STA‐1474 and evaluated for effects on proliferation (CyQuant), apoptosis (Annexin V, PARP cleavage, caspase 3/7 activation) and known HSP90 client proteins. HSP90 was immunoprecipitated from normal and malignant osteoblasts and Western blotting for co‐chaperones was performed. Mice bearing canine OSA xenografts were treated with STA‐1474, and tumors samples were evaluated for caspase‐3 activation and loss of p‐Akt/Akt. Treatment with STA‐1474 promoted loss of cell viability, inhibition of cell proliferation and induction of apoptosis in OSA cell lines. STA‐1474 and its active metabolite STA‐9090 also demonstrated increased potency compared to 17‐AAG. STA‐1474 exhibited selectivity for OSA cells versus normal canine osteoblasts, and HSP90 co‐precipitated with co‐chaperones p23 and Hop in canine OSA cells but not in normal canine osteoblasts. Furthermore, STA‐1474 downregulated the expression of p‐Met/Met, p‐Akt/Akt and p‐STAT3. Finally, STA‐1474 induced tumor regression, caspase‐3 activation and downregulation of p‐Met/Met and p‐Akt/Akt in OSA xenografts. Together, these data suggest that HSP90 represents a relevant target for therapeutic intervention in OSA. © 2009 UICC


The original algorithm for the search of the shortest way the application of which contributes to the reduction of supplementary time at the expense of the decrease of tool idling is presented. There are considered other algorithms for the search of the shortest way and their comparative analysis is carried out. The objective data on advantages of the algorithm presented in finding the shortest way on a plane are presented.


The basic thought of Simulated Annealing algorithm is introduced in this paper. This algorithm is successfully used to solve the problem of optimal calculation of the minimum spanning tree of communication network. The computed result indicates that the algorithm can jump out of the local optimization efficiently and constringe the global optimization quickly. So, the Simulated Anneaning algorithm is a general, powerful combinatorial optimization algorithm with the ability to ascend according to the probability.


The soleus, a slow‐contracting muscle, and the extensor digitorum longus (EDL), a fast‐contracting muscle from guinea‐pig were prepared for isometric recording in vitro. Sub‐tetanic contractions were evoked by transmural field‐stimulation. Pentobarbitone increased the force of contraction in both muscles. In the soleus it shifted the stimulation frequency‐response curve to the left. Terbutaline caused a decrease in the force of subtetanic contractions of the soleus, an effect which was dependent on the stimulation frequency. In the presence of pentobarbitone, the stimulation frequency had to be lowered by about 2 Hz in order to maintain the optimum response to terbutaline. The EDL responded to terbutaline with an increased force of contraction. In this case the stimulation frequency was less critical and the effects were the same in the presence and in the absence of pentobarbitone. Experiments with α‐chloralose yielded results similar to those obtained with pentobarbitone.


Urbanization level is an important concept and measure index in urbanization study. Researchers are used to measuring urbanization level by the percentage of urban population occupying the total population. It is a fairly feasible method and also the most scientific one in all related single index methods, particularly in some areas where necessary data are incomplete. On the other hand, this method has not a few limits, because the only index of city population can't cover all content of urbanization. By this method, the urbanization level of outside area of Shenzhen Economic Development Zone reaches over 90%, but it is not the fact. By using compound index, ergodic hypothesis and index compare, this study measured the level of outside area of Shenzhen Economic Development Zone respectively, and got an actual outcome.


To build a strong country, build strong teaching. But teaching surrounding multiple risks. So this paper aims to identify and assess risks in teaching. The assessment risks in sanda teaching is a critical task and contain multiple conflict criteria. So we use Multi-Criteria Decision Making (MCDM). In this paper, we use an Analytical Hierarchy Process (AHP) to rank and compute each criterion's weights. We use five main and twenty sub-criteria. These criteria were evaluated under a neutrosophic environment—an example provided to present the outcomes of the proposed model.


The complexity of control of large technical systems coupled with the time-consuming process of obtaining and processing of the factual data from the operational documentation contributes to the situation with discrepancies in the real state of the system and the status reflected in the documentation. This reduces the information entropy of the system and the number of incorrect management decisions. Thus, adoption of control solutions for large and complex technical systems is only possible, if they meet the conditions of the admissible value of the entropy. The task of monitoring of the information entropy of large complex technical systems should be solved with an automated control of quantifying the information entropy of the system, which leads to conclusion about a possibility of making control solutions based on the stored factual data. The paper describes the method of a qualimetric evaluation of the information entropy of large technical systems based on operational models of a semistructured content. This method is based on an automated analysis of a group of decision-makers of the factual content associated with the operational documentation generated during operation of the identified system. Use of the semistructured content model implements a universal interface with access to the factual data of the electronic documents, which reduces the number of the processing errors and increases the processing speed of the factual content. The latter reduces the total information entropy of the driven system.

The connection between pathophysiological experiment practice and clinics plays primary role in strengthening students' abilities in doing and clinical thinking. It also enables them to understand the mechanisms underlying the development of diseases. Through the experimental design, designed questions and case discussion, pathophysiological experiment teaching can be integrated with clinics and arouse students' enthusiasm. All above is the basis of clinical teaching.


Using the evolutionary game theory,the paper analyzes the collaboration and competition between the contractor and the owner in an engineering project supply chain and finds that without the binding of the contract,the coopration between the two will be influenced by the initial state of the cooperation while under contract,the two will choose to keep on cooperating.


This paper explores the nature of default arrival and recovery implicit in the term structures of sovereign CDS spreads. We argue that term structures of spreads reveal not only the arrival rates of credit events (λ Q ), but also the loss rates given credit events. Applying our framework to Mexico, Turkey, and Korea, we show that a single-factor model with λ Q following a lognormal process captures most of the variation in the term structures of spreads. The risk premiums associated with unpredictable variation in λ Q are found to be economically significant and co-vary importantly with several economic measures of global event risk, financial market volatility, and macroeconomic policy. THE BURGEONING MARKET FOR SOVEREIGN CREDIT DEFAULT SWAPS (CDS) contracts offers a nearly unique window for viewing investors' risk-neutral probabilities of major credit events impinging on sovereign issuers, and their risk-neutral losses of principal in the event of a restructuring or repudiation of external debts. In contrast to many "emerging market" sovereign bonds, sovereign CDS contracts are designed without complex guarantees or embedded options. Trading activity in the CDS contracts of several sovereign issuers has developed to the point that they are more liquid than many of the underlying bonds. Moreover, in contrast to the corporate CDS market, where trading has been concentrated largely in the 5-year maturity contract, CDS contracts at several maturity points between 1 and 10 years have been actively traded for several years. As such, a full term structure of CDS spreads is available for inferring default and recovery information from market data. This paper explores in depth the time-series properties of the risk-neutral mean arrival rates of credit events (λ Q ) implicit in the term structure of sovereign CDS spreads. Applying our framework to Mexico, Turkey, and Korea, three countries with different geopolitical characteristics and credit ratings, we ∗ Pan is with the MIT Sloan School of Management and NBER.

! This study investigated the incidence and frequency of injuries in moutainbike sports among competitive and recreational athletes. In a retrospective study design mountain-bike athletes were interviewed by means of a standardized questionnaire with regard to sports injuries and damages within the previous two years. The evaluation of time relative injury-rate was carried out under consideration of class and competition discipline. 75% of the distributed questionnaires returned completed by 106 World-Cup (39 , 67 < , 23.1y) and 134 recreational athletes (17 , 117 < , 27.4y). Approximately 80% of the World-Cup and about 50% of the re-creational athletes reported about at least one severe injury. World-Cup downhill athletes (1.08 injuries/1000h) show a more than doubled time-related injury-rate in comparison with Cross-Country athletes (0.39 injuries/1000h). Injuries of the lower (47 vs. 35%) and upper extremity (40 vs. 41%) show comparable prevalence for competitive and recreational cyclists. In the group of recreational athletes open wounds dominate, competitive athletes demonstrate a significant higher fracture-rate (p<0.01). Within the World-Cup athletes head injuries stand out (n=40). Although World-Cup participation does not result in essential injury-increase, the down-hill discipline is characterized by a higher injury risk. Presumably in view of the performance orientation, there is a higher degree


Objective To observe the delayed protective effects of ramipril on myocardial ischemic-reperfusion injury in isolated rat hearts and explore the possible mechanisms.Methods The isolated rat hearts were chosen to make the model of myocardial ischemic-reperfusion injury by developed Langendorff methods.Thirty-five rats were divided into 5 groups randomly:(1) control group;(2) ischemia-reperfusion group;(3) ramipril treatment groups(0.05 or 0.1 mg/kg);(4) Hoe140(0.1 mg/kg) + ramipiril(0.1 mg/kg) group.Left ventricular pressure(LVP),the first derivative of LVP(+dp/dtmax),left ventricular end-diastolic pressure(LVEDP) and heart rate(HR) were recorded.Coronary flow(CF) and creatine kinase(CK) activity were measured by timed collection of coronary effluent.At the end of the reperfusion,the content of malondialdahyde(MDA) was measured.Results(1) 30 minute of global ischemia and 10,20 or 30 min of reperfusion caused a significant cardiac dysfunction as shown by the reduction of LVP and +dp/dtmax,the elevation of LVEDP,and an increase in the release of CK and MDA during reperfusion;and 20 or 30 min of reperfusion caused a significant decrease in HR.(2) Ramipril(0.05 mg/kg) at 24 h after 30 minute of global ischemia and 20 or 30 min of reperfusion raised significantly LVP,CF and +dp/dtmax,decreased LVEDP.(3) Ramipril(0.1 mg/kg) at 24 h after 30 minute of global ischemia and 10,20 or 30 min of reperfusion raised significantly LVP,CF and +dp/dtmax,decreased LVEDP.(4) The myocardial protection of ramipril was inhibited by HOE140,a bradykinin B2 receptors antagonist.(5) The release of CK in ischemia-reperfusion(30 min ischemia and 10,20 or 30 min reperfusion) group were significant increased compared with control,while ramipril treatment(0.05 or 0.1 mg/kg) significantly inhibited an increase in the release of CK induced by ischemia-reperfusion;pretreatment with HOE140 markedly decreased the effect of ramipril on the release of CK.(6) Pretreatment with ramipril(0.05 or 0.1 mg/kg) 24 h before the experiment caused a significant reduction of the release of MDA compared with ischemia-reperfusion group.Conclusion These results suggest that the delayed cardioprotection afforded by ramipril may be related to inhibition of bradykinin degradation.


Since the advent of democracy in South Africa rural and disabled people have lagged behind in terms of access to services, and that has implications on their enjoyment of socio-economic rights. Although exclusion from access to services is documented in literature, little research has been done to explore rural and disabled people's perspectives on inclusive service delivery. The purpose of this study was to contribute to the literature regarding inclusive service delivery in health, education and social development and citizen participation in rural areas. Insights into perspectives of rural citizens are pertinent for improved and inclusive service delivery. The aim of this study was to describe the perspectives of rural people regarding disability inclusive public sector service delivery in social development, health and education in a remote village in the Eastern Cape, South Africa.

The media-enhanced teaching techniques became popular in the last years because they stimulate the students' engagement and motivation. The educational movies uploaded on YouTube became nowadays a highly used resource for learning in the academic environment. We conducted an opinion survey among the students at the Faculty of Dental Medicine, "Grigore T. Popa" University of Medicine and Pharmacy, Romania, about their agreement and interest in using educational movies as didactic tools, compared with the traditional teaching methods, and about the features they prefer in such materials. The study group included 170 students with average age 20.93 ± 2.751. Most students (91.2%) use didactic movies in their practical training; 77.6% think that the didactic movies from YouTube contain correct scientific information. 74.6% of the students like to learn using didactic movies, 39.7% of them appreciate the oral speech accompanied by PowerPoint Presentations and 46.6% like the oral speech accompanied by written explanations, with no significant differences between genders and age groups. The most popular features of the educational movies are: human narrator (94.7%), who speaks in Romanian (82.4%). The narrator's speech must be accompanied by animated schemes with explanations (90.6%) and drawings (93.5%). The movie must have a clear structure, evolving from basic to complex (85.9%). The educational movies uploaded on YouTube are an adequate source of information for the dental students; the professionals in universities must survey better the scientific quality of such materials.


. In this work we present near-IR spectra (HK-band) of a sample of 107 sources with mid-IR excesses at 7 and 15 µ m detected during the ISOGAL survey. Making use of the DENIS interstellar extinction map from Schultheis et al. (1999) we derive luminosities and find that the M bol vs. 12 CO and M bol vs . H 2 O diagrams are powerful tools for identifying supergiants, AGB stars, giants and young stellar objects. The majority of our sample are AGB stars ( ∼ 80%) while we find four good supergiant candidates, nine young stellar objects and 12 RGB candidates. We have used the most recent K 0 − [15] relation by Jeong et al. (2002) based on recent theoretical modeling of dust formation of AGB stars to determine mass-loss rates. The mass-loss rates of the supergiants are comparable with those in the solar neighbourhood while the long-period Variables cover a mass-loss range from − 5 < log ˙ M < − 7. The red giant candidates lie at the lower end of the mass-loss rate range between − 6 . 5 < log ˙ M < − 9. We used the equivalent width of the CO bandhead at 2.3 µ m, the NaI doublet and the CaI triplet to estimate metallicities using the relation by Ram´ırez et al. (2000b). The metallicity distribution of the ISOGAL objects shows a mean [Fe/H] ∼ -0.25 dex with a dispersion of ± 0 . 40 dex which is in agreement with the values of Ram´irez et al. (2000b) for Galactic Bulge fields between b = − 4 o and b = − 1 . 3 o . A comparison with the solar neighbourhood sample of Lan¸con & Wood (2000) shows that our sample is ∼ 0.5 dex more metal-rich on average.


In contexts as diverse as civil war interventions, alliances, and military coalitions, states often militarily assist protégés to counteract unfavorable power shifts. Existing theoretical work finds that such assistance mitigates commitment problems and reduces the probability of war. We develop a model that captures this but also includes information asymmetries. In many cases, overcoming the commitment problem encourages the protégé to take greater risks in bargaining, thereby increasing the probability of war due to incomplete information. Using mechanism design, we show that in some cases, no feasible transfer can reduce the probability of war to zero. More broadly, our results indicate that encouraging policymakers to further expand military assistance can backfire despite empirical relationships that may appear otherwise.


A Boscan crude, an Athabasca bitumen and a Khafji vacuum residue were chosen as typical asphaltenic feedstocks for this study, since they contain a lot of asphaltenes as well as sulfur and their metal contents are considerably different from one another. Any changes on these asphaltenes caused by metals and sulfur removal should, therefore, be observed easier than on other asphaltenes similar to one another. Various measurements reported here vapor pressure osmometry, gel permeation chromatography, nuclear magnetic resonance, x-ray diffraction, small angle x-ray scattering and electron spin resonance are mainly for the asphaltenes isolated from these feedstocks and from their product oils. Further, the model of the asphaltene cracking mechanism is proposed from these results and is discussed in the correspondence with the activities and selectivities among demetallation, desulfurization and asphaltene cracking. The features of asphaltene cracking are summarized as follows: (1) the removal of vanadium and sulfur from asphaltenes; (2) the decrease of molecular weight of remaining asphaltene; (3) the decrease of unit number and no change of unit sheet weight; (4) no change of asphaltene macrostructure in the stacking portion (cracking occurring at the non-stacked portion); (5) no major change of asphaltene particle size; and (6) the changemore » of vanadyl association type in remaining asphaltenes from free to bound state and the decrease of the dissociation energy of the vanadyl. According to these features, the model of asphaltene cracking previously proposed, was confirmed, where the main reactions are the destruction of asphaltene micelles caused by vanadium removal and the depolymerization of asphaltene molecules by removal of heteroatoms such as sulfur. By comparing the model with the reactivities and selectivities, it is shown that the contribution of the two reactions in the model for asphaltene cracking depends on the kinds of feedstocks.« less


There are several motivations for this paper; it can inspire consideration to the cultural exchanges between Korean literature and Chinese literature which overlooked in the history of modern Korean literature, it can give a chance to reconsider the outcome of Korean and Chinese literature in early 20 century which has been far undervalued, and it can give an opportunity to review the relation between Korean literature and Chinese literature which has been little studied in the history of modern Korean literature. In the history of modern Korean literature, Yang Kun Sik's efforts as a messenger of Chinese literature achieved fruitful results. Heworked very hard to translate and spread not only modern Chinese literature but also Chinese classic novels and plays. While most of intellectuals advocated civilizations and reforms of the West and Japan, only Yang Kun Sik translated and introduced Chinese traditional novels not for restoration but for our own modernization based on the harmony of the newness of the West and the objective evaluation of traditional literature. As a conclusion, it is necessary to set a new and high valuation on the literary result and value of Yang Kun Sik"s acceptance and translation of Chinese literature in the history of modern Korean literature.


Partitioned stator flux reversal permanent magnet (PS-FRPM) linear machine is a type of permanent magnet linear machine with dual active stators and one passive mover. Pervious work was shown that such a machine possesses the advantage of having big slot area leading to reduced phase resistance and consequently improved electric loading capability.

Abstract. The lecture presents modern data on systemic inflammation, as well as an original concept of its genesis. This disorder is considered a typical pathological process being fundamental to pathogenesis of the most critical states of different origin. Distinct features of "classical" and systemic inflammation are discussed, whereas the underlying immunological and pathophysiological mechanisms of inflammation are subject to classification. Main constitutive processes, phases of systemic inflammation, and certain variants of their proceeding are characterized as well. A definition of "systemic alteration" has been specified.


Gamcheon Culture Village has become a tourist attraction. Initially it was germinated by the dedicated efforts of the local government officials and local artists. Now the active participation of the local community is very important. Sustainability of community building is impossible without residents participation. So we must see the residents' roles of this decision-making process. Viability of the community business at this village should be checked. Finally they must manage it for themselves without help from local government officials and urban regeneration experts. Gamcheon Culture Village is both residential area and tourist attraction. Changing declining residential areas into tourism development is not general regeneration method. Community building is the movement taking a long time. So it is not right to judge the success or failure of this village because the community building of Gamcheon Culture Village is currently underway.


In the nonrelativistic case of the Schrodinger equation, composite particles correspond to Regge poles in scattering amplitudes (poles in the complex plane of angular momentum). It has been suggested that the same may be true in relativistic theory. In that case, the scattering amplitude in which such a particle is exchanged behaves at high energies like sα(t)[sinπα(t)]-1, where s is the energy variable and t the momentum transfer variable. When t=tR, the mass squared of the particle, then α equals an integer n related to the spin of the particle. In contrast, we may consider the case of a field theory in which the exchanged particle is treated as elementary and we examine each order of perturbation theory. When n>1, we can usually not renormalize successfully; when n≤1 and the theory is renormalizable, then the high-energy behavior is typically sn(t-tR)-1φ(t). Thus an experimental distinction is possible between the two situations. That is particularly interesting in view of the conjecture of Blankenbecler and Goldberger that the nucleon may be composite and that of Chew and Frautschi that all strongly interacting particles may be composite dynamical combinations of one another. We suggest a set of rules for finding the high-energy behavior of scattering cross sections according to the Regge pole hypothesis and apply them to π-π, π-N, and N-N scattering. We show how these cross sections differ from those expected when there are "elementary" nucleons and mesons treated in renormalized perturbation theory. For the case of N-N scattering, we analyze some preliminary experimental data and find indications that an "elementary" neutral vector meson is probably not present. Various reactions are proposed to test the "elementary" or "composite" nature of other baryons and mesons. Higher energies may be needed than are available at present.


Through analysis and research of monitoring data and construction data of an experimental road section of an expressway in weak soil area in Ningbo, Zhejiang Province, it is found that there is a certain relationship between the settlement sectional area and the central settlement of subgrade under different loads when the conditions of weak foundations are similar and the foundations are treated by the different consolidation methods. So a fairly practical calculation formula is presented here.

As a result,there was a shortage of goods and services and the prices of goods went up.As a result,the poor, the middle class and the rich were severely affected economically.


The emergence of modern cloud computing has brought a revolution in various fields by providing scalable and readily available computational resources, enabling efficient data processing. These advancements have significantly enhanced the connectivity between local and remote systems, facilitating streamlined data transmission processes. Furthermore, the adoption of Software as a Service models has allowed the hosting of programs and applications in the cloud, offering accessibility, scalability, and cost savings. These advancements have not gone unnoticed in the power system domain. Applications such as monitoring, and protection can take advantage of the improved telecommunication technology. Phasor Measurement Units (PMUs) play a vital role in these applications by synchronizing quantities obtained from instrument transformers and computed quantities using precise time stamps. The objective of this paper is to conduct a comprehensive analysis of the pros and cons associated with a cloud-based PMU (CB-PMU) that integrates the PMU Synchrophasor estimation directly into the cloud infrastructure. This approach has received limited attention in existing literature, underscoring the necessity for this in-depth study. The analysis in this paper is both theoretical and experimental. The results allow for a complete assessment of the applicability and the limits of the CB-PMU.

In the present day, the media is one of the most important and influential means of social communication from the viewpoint of Shi'a religious jurisprudence. On the other hand, one of the sciences that can set norms for the media considering its universality is the science of "Religious jurisprudence". Among the religious jurisprudential propositions, the "expedience" rule can have the most impact on setting the norm for the media. Accordingly, the main question of this research is, "what is the status and use of the expedience institute in the media?" The research hypothesis is that expedience is the most important rule governing the media and its activities, which used the documentary method to investigate this hypothesis. The findings of this research are that the element of expedience in the media determines the propagation of news and information. It was also found that maintaining the country's livelihood and political system, justice and security are among the most important incentives, which are the most important materials that should govern media activities in order not to harm one of them. Therefore, this article is organized to explain the concept of religious jurisprudential expedience in the media and to study the motivations and introduce the expedience determining reference in the media.


This work investigates the validity of quasi-linear (QL) diffusion theory and the significance of finite ion orbit effects on Ion Cyclotron Resonant Heating (ICRH) in Tokamak plasmas. By comparing QL diffusion coefficients with exact values calculated by direct Lorentz orbit integration in full-wave RF electric fields (with the DC code), we examine the issues of (i) neglecting correlations between successive resonant surface crossings, and (ii) including a realistic toroidal antenna spectrum. The impact of finite ion orbits are assessed by examining moments of the ion distribution under a selfconsistent full-wave / Monte-Carlo iterative calculation.


Finite element method was used to simulate the residual stress in soldered joints of QFP device with three kinds of lead materials.The results indicate that all the stress concentration area in soldered joint is at the sharp corner of interior part of the joint where is the weakest area of the joint.Comparing with the simulating results about alloy-42,copper alloy and Kovar alloy,especially analyzing the nephograms of equivalent strain and the strain and stress curves,it is shown that the stress and strain makes periodic change with the time,simultaneously has the accumulated tendency,and the value of strain and stress in the soldered joint of alloy-42 gull is the least,and the value is middle in the joint of Kovar alloy,and the value was largest in the joint of copper alloy.The simulating results may provide a theory guide for developing novel lead material as well as selecting lead materials in production.


Increases in performance and logic capacity are allowing FPGA devices to be used by many engineers for fast prototyping. However, at annual volume of more than tens of thousands, the lower unit cost of mask gate array entices the user to consider converting the design. But it is not easy migration, given such problems as timing incompatibility and testing. We will list the issues which must be considered while converting FPGA to mask gate array. On the other hand, to make the design conversion easy a Migration Tools-Set, MITS, is designed and is under development. It does not solve all the problems involved in converting an FPGA design to a gate-array design. But it will give much help, and do much tedious calculation for the user.


This study aims to determine the practices of child commodification in a South Korean variety show: The Return of Superman (TROS). This study uses qualitative research methods through Van Dijk's critical discourse analysis (CDA). The results show that there was a commodification of children hidden behind the title of the program; this program is a product of popular culture with capitalist practices as a background: profit-oriented and market-regulated; and variety show interpreted more negatively because it has exploited the commodification practices and abuse of children's rights in the interest of the media.

Numerically simulated ultrasonic density and pressure fields are compared with the schlieren pictures of the same field. The validation of the schlieren visualization is presented. From the experiment in which the gas jets through the nozzle against the piston surface, it can be concluded that in the case without ultrasound application, the gas flow leaving the nozzle does not significantly diverge and forms a boundary layer along the piston surface. In the presence of an ultrasonic field, the gas flow pattern is changed in a very similar way to the simulated ultrasonic pressure maximum gradient distribution. The results are used to explain the interaction of the gas flow with the ultrasonic field generated by the piston. Knowledge of these density distributions is required for the description of more complex processes, which take place if an electrical discharge is formed between the nozzle and the ultrasonic transducer. Such combined electrical and aerodynamic phenomena are presented in environmental applications such as production of ozone, VOC decomposition and de-NOx processes enhancement.


Recent years, cloud computing is description for facilitating suitable on-demand network access. In cloud, computing multi-tenancy plays a significant role on software as a service (SaaS). Structure of SaaS multi-tenant cloud aware applications initiates several new challenges the central one being a tenant. In cloud testing, tenant applications need to be tested in addition to performance testing be used. At the same time as numerous performance-testing techniques exist; most of them produce only fixed progressions of test configurations. This paper focuses on the challenges for Multi-tenancy testing in SaaS and analyses the configuration dynamically in which SaaS testing differs from testing conventional applications. The paper proposes performance testing and fittest function of each tenant. For fitness function, GASE algorithm is used which combines a genetic algorithm and a symbolic execution. This proposed algorithm uses the above performance testing values for obtaining the best of each tenant, in the form of fitness generations. A real experimentation is proposed using a multiple tenants on open stack cloud computing environment over social networks.


This study aims to assess the nutritional intake in mentally disabled people and find out the solution for nutritional improvement. People with intellectual disability(N=40), mental disability(N=45), autism(N=4) and brain lesion(N=4) participated in this study. The disorder grades were from I to III and ages between 5 and 65. Assessments included anthropometry, ROMA III questionnaire for assessing bowel movement, daily intake of nutrients including phytochemical. The average BMI of mentally disabled people was the range of obesity. The intakes of protein(p<0.001), iron(p=0.001) and vit B₁(p=0.025) in mentally disabled people were lower than that of the non‐disabled people from the second year 2011 of the 5th National Health and Nutrition Survey. The intakes of iron(p<0.001) and vit B₁(p<0.001) in people with intellectual disability were also low. The intake of tocopherol was low in intellectually disabled group compared with traditional Korean diet of the non‐disabled people from the second year 2008 of the 4th National Health and Nutrition Survey. While cryptoxanthin, lycopene, tocopherol intakes were low in mentally disabled group. In conclusion, we recommend that it is important to encourage people with mental disability to eat sufficient amounts of vitamins, minerals, phytochemical nutrients in order to promote nutritional status.

Firstly, 2, 204 EST sequences of tree peony were downloaded from the database of NCBI, then redundant sequences were removed and 1,658 non-redundant ESTs were obtained. The results showed that a total of 1,111 SSRs were detected, with the frequency for the non-redundant ESTs being 67.00%. Among the different SSRs motifs, the amounts of repeats sorted as mononucleotide, dinucleotide and trinucleotide repeats. A/T, AG/CT and AAG/CCT are the most frequent motifs. Based on the screened sequences, 29 SSR primer pairs were developed, of which 13 pairs had amplified successfully within the expected size range and showed abundant polymorphisms. They were used to amplify in 55 cultivars of tree peony. Based on the SSR results, the similarity coefficients of the 55 cultivars varied between 0.53 and 0.95. According to the constructed UPGMA cluster, the 55 cultivars could be classified into two groups at 0.53, which was approximately in accordance with their diversity of culture area, and provided a scientific basis for selection of parents for hybridization of tree peony.


Description Syntax Remarks and examples References Also see Description mgarch estimates the parameters of multivariate generalized autoregressive conditional-heteroskedasticity (MGARCH) models. MGARCH models allow both the conditional mean and the conditional covariance to be dynamic. The general MGARCH model is so flexible that not all the parameters can be estimated. For this reason, there are many MGARCH models that parameterize the problem more parsimoniously. mgarch implements four commonly used parameterizations: the diagonal vech model, the constant conditional correlation model, the dynamic conditional correlation model, and the time-varying conditional correlation model.
