Automatic fare gate is an important facility of passenger flow in rail transit station. During the process of passing automatic fare gate, a series of activities will occur such as deceleration, card swiping, waiting and passing, all of these will influence the continuity of passenger flow, so the rationality of automatic fare gate distribution has important role on collecting distributing efficiency of station. Through studying the distribution of automatic fare gate in urban rail transit station, two typical distribution form of automatic fare gate was defined and its pedestrian simulation model was established respectively, then the simulation was taken by taking Dalian light rail Line 3 as example. The simulation result shows: the parallel distribution pattern is superior to the vertical distribution pattern on the aspects of balance degree of automatic fare gate utilization and passengers' space distribution rationality in station.


Chocolate and Chess (Unlocking Lakatos) tells the fascinating story of Imre Lakatos' life in Hungary before his flight to England following the failed 1956 Hungarian Revolution. The book focuses on Lakatos' role as a political functionary under Hungarian Stalinism, and compiles what is known of Lakatos' role in the induced suicide of a young woman, Éva Iszák, at the end of World War II. This historical and biographical study provides essential background for appreciating Lakatos' cross-cultural role as a philosopher in England and Hungary, through the Anglo-American philosophy and the Hegelian-Marxist traditions in which he was trained and did not leave behind.


This paper first analyzes the major factors in the development of the information technology in the American higher education: government guidance, strategic management, marketing orientation, competition, cooperation, creation and benchmarking. Then it proposes some constructive measures for accelerating the process of the informationization in China's higher education.


As the culture of information technology grows and with it the exacerbation of associated problems, so does the body of literature that seeks to reflect on its impact and prospects. The advancements in information technology tend to be outpacing critical reflection and solid ethical analysis. The quality of the foundational ethical work done in information technology ethics has been inadequate, consisting of applied ethics or an appeal to law. This article considers how the richer perspective—the common good, as expressed through the lens of the Roman Catholic Church—can serve as a hermeneutic in the field of information technology ethics, offering a more substantial foundation to address pressing controversial issues associated with this burgeoning field and function as a guide for future developments in this industry. The common good can supplement the operative ways of appealing to law and business ethics to address crime and abuse associated with the World Wide Web with a specifically Roman Catholic paradigm and, in turn, offer a broader and richer appreciation of the societal-wide context that information technology impacts.


: Burnout, depression, low job satisfaction level effect on nurses performance badly. I have been observed multiple time that the staff nurses of ICU does not take interest to pay attention towards their duties as honestly and passionately as their profession demand to be.whereas, the other thing which was observed they were not concern how the negligence of duty performance impact on the recovery of cardiac patient who need more intensive care after heart surgeries. Staff nurses of every shift makes dispute on handed and taking over the patient. In this regard a study conducted in Iran on the "Predictors of happiness among Iranian Nurses" which result show by multiple regression analysis that there is a strong correlation with self-actualization and self-esteem with job satisfaction and happiness

How can Kant's perpetual peace be reallized?Kant's theory of natural end guarantees the requirements for perpetual peace.The distinction of right and morality and the difference between natural end and moral end demonstrate that the significance of perpetual peace in Kant's theoretical system lies in the conditions it provides for the change from reflection to the realization of moral end.


The utility model discloses a multi-type sensor general interface which is used for connecting a sensor, including a power line, a ground wire, a sensor output signal wire, a sensor type coding line and a controlling device. The sensor output signal wire and the sensor type coding line are connected with the controlling device. The power line is equipped with a supply power choosing switch which is connected with the controlling device. The supply power choosing switch controls the power line to output relative working voltage to the sensor. The utility model can be connected with sensors of different types, which solves the problem that the present interface cannot be relatively connected with sensors with different working voltages.

Four new species of Heza are described, compared with related taxa, and partial keys are given to separate the new from the old species. New records are added to the known geographical distribution of five species of this Neotropical genus.


Each year of deficit spending results in new borrowing and a higher and higher national debt. In turn, the growing national debt increases the interest payments the government must make. In 2012, debt service—the amount the government must pay to cover the interest on the federal debt—was $220 billion, or more than the federal government spent on agriculture, education, energy and transportation, combined. WHAT'S THE TAKEAWAY?


NbN phonon cooled hot electron bolometer (HEB) mixers are currently the most sensitive heterodyne detectors at frequencies above 1.2 THz. They combine a good sensitivity (8-15 times the quantum limit), an IF bandwidth of the order of 4-6 GHz and a wide RF bandwidth from 0.7-5.2 THz. However, for use in a space based observatory, such as Herschel, it is of vital importance that the Local Oscillator (LO) power requirement of the mixer is compatible with the low output power of present day THz LO sources. This can be achieved by reducing the mixer volume and critical current. However, the large RF bandwidth and low LO power requirement of such a mixer result in a direct detection effect, characterized by a change in the bias current of the HEB when changing the RF signal from a black body load at 300 K to one at 77 K. As a result the measured sensitivity using a 300 K and 77 K calibration load differs significantly from the small signal sensitivity relevant for astronomical observations. In this article we describe a set of dedicated experiments to characterize the direct detection effect for a small volume quasi-optical NbN phonon cooled HEB mixer. We measure the direct detection effect in a small volume (0.15 μm · 1 μm · 3.5 nm) quasioptical NbN phonon cooled HEB mixer at 1.6 THz. We found that the small signal sensitivity of the receiver is underestimated by approximately 35% due to the direct detection effect and that the optimal operating point is shifted to higher bias voltages when using calibration loads of 300 K and 77 K. Using a 200 GHz wide band-pass filter at the 4.2 K the direct detection effect virtually disappears. Heterodyne response measurements using water vapor absorption line in a gas cell confirms the existence and a magnitude of a direct detection effect. We also propose a theoretical explanation using uniform electron heating model. This direct detection effect has important implications for the calibration procedure of these receivers in real telescope systems. 16th International Symposium on Space Terahertz Technology

The mitochondrion of animals is a organelle appearing in cytoplam of eukaryotes. According to the complete sequences that have been sequenced,it contains genes encoding 13 proteins,2 rRNAs,22 tRNAs and one major non-coding region(D-Loop).It is reported that a R-Loop structure has been found,with the characteristics of maternal inheritance,and the average evolution rate is 10 times faster than that of nuclear genome,especially D-Loop.The existence of tandemly repeat sequences in control region of mitochondria would be regarded as a special molecular marker in animals researches because of the interspecies and intraspecies differences.According to the structural and genetic characteristics of mtDNA,by means of advanced bioinformatics and rich databases,the researchers have made great progress in the field of molecular phylogenetics of animal populations,and make certain taxonomic status,interspecies and intraspecies relationship.


Facile synthesis of novel monodisperse liquid-crystalline (LC) oligomers was performed. The functionalization of the end group of 4 (and 6) millipede cyanoacetates with 8 (and 12) mesogenic units by Michael addition reaction produced a monodisperse LC octamer (and dodecamer) in high yields. Differential scanning calorimetry and optical polarizing microscopy revealed LC properties of the synthesized LC monodisperse oligomers. The monodisperse LC oligomers were morphologically stable glass-forming LC materials and exhibited a large variation in nematic phase temperatures in the range of approximately 80 to 300 °C.


Zimbabwe has recently gone through a widely criticised land reform process that is argued to be the cause of subdued agricultural production. This paper attempts to present a counterfactual picture of the maize market in Zimbabwe had land reform been managed appropriately. The counterfactual is developed through a partial equilibrium framework in order to quantify the impact of the land reform programme. This, to our knowledge, is the first attempt at applying a partial equilibrium framework to an analysis of the impact of land reform. The results of the post-2000 land reform policy simulation showed that actual total maize output was lower than what could have been produced if it was under a pre-2000 land reform system. The study validates the assertion that land reforms contributed to the contraction of output. These results suggest the need for a well planned and executed land reform process, which can still play an important role in output growth and food security.


TRISO coated fuel particle is developed for using nuclear fuel for HTGR(High Temperature Gas-cooled Reactor). TRISO coating layer is generally composed of four layer of buffer PyC layer, inner PyC layer, SiC layer, and outer PyC layer. SiC layer maintains the structural integrity of TRISO coated fuel particle at high temperature and retains fission products. SiC layer has excellent mechanical properties at high temperature but also has some problem at high temperature. -SiC deposited by CVD method cause a phase change to SiC above 1800 C, which may cause damage to the coating layer. Since the SiC layer reacts with the fission product Pd to form Pd2Si, which causes corrosion, resulting in a loss of Cs trapping ability of TRISO coated fuel particle[1,2] ZrC coating layer, which is high temperature ceramics, has been proposed as an alternative coating layer due to its low reactivity with fission products and high temperature stability. ZrC has excellent corrosion resistance against Pd so that the coated particles are not broken at 2400 C[3,4]. However, ZrC coating is difficult to fabricate with a Zr/C stoichiometric ratio of 1:1 because ZrC is thermodynamically more likely to form ZrC+C or Zr1+xC than pure ZrC. The free carbon or carbon vacancy within ZrC coating reduces the mechanical and radiation resistance of the ZrC coating [5,6]. In this study, various stoichiometry ZrC coatings were fabricated by two kinds of source gas supply method. The elastic modulus and the hardness using nanoindentation, and the fracture strength using a crush test were measured according to the stoichiometry of ZrC.


The translational activity of various unsaturated analogs of L-isoleucine was evaluated using an Escherichia coli strain auxotrophic for isoleucine. It was observed that the alkene [2-amino-3-methyl-4-pentenoic acid (2)] and alkyne [2-amino-3-rnethyl-4-pentynoic acid (3)] derivatives of L-isoleucine can support protein synthesis at levels approximately 50% of that observed in cultures supplemented with isoleucine. However, no incorporation of the αC or βC methylated derivatives could be detected. In order to examine the stereoselectivity of incorporation, the (2S, 3s) and (2S, 3R) diastereomers of 2 and 3 were prepared. The extents of isoleucine substitution in vivo were 80% and 70% for (2S, 3S)-2 and (2S, 3S)-3, respectively, under the conditions examined in this study.


In this study, hemodynamic forces in a three-dimensional (3D) computational model of Coronary Artery Bypass Grafting (CABG) with deformable and rigid walls were compared. A physiologic pulsatile non-Newtonian blood flow was considered in the arteries for both models. The artery walls in the distensible model were considered to be hyper-elastic with nonlinear strain dependent Young's module and axial and radial degrees of freedom, while the deformability in all directions of the rigid model was restricted. The velocity distributions and magnitudes, vortex motions and the occurrence of recirculation zones were selected as the primary hemodynamic parameters in order to show the effect of deformability in the arterial wall and in calculating differences versus the rigid wall model. It was found that during systolic, the velocity magnitude at the host artery bed could vary by up to 80% depending on the longitudinal distance from the center of the anastomosis junction.Copyright © 2008 by ASME


The resolution of a very large class of linear and non-linear, stationary and evolutive partial differential problems in the half-space (or similar) under the slip boundary condition is reduced here to that of the corresponding results for the same problem in the whole space. The approach is particularly suitable for proving new results in strong norms. To determine whether this extension is available, turns out to be a simple exercise. The verification depends on a few general features of the functional space X related to the space variables. Hence, we present an approach as much as possible independent of the particular space X. We appeal to a reflection technique. Hence a crucial assumption is to be in the presence of flat boundaries (see below). Instead of stating "general theorems" we rather prefer to illustrate how to apply our results by considering a couple of interesting problems. As a main example, we show that the resolution of a class of problems for the evolution Navier-Stokes equations under a slip boundary condition can be reduced to that of the corresponding results for the Cauchy problem. In particular, we show that sharp vanishing viscosity limit results that hold for the evolution Navier-Stokes equations in the whole space can be extended to the boundary value problem in the half-space. We also show some applications to non-Newtonian fluid problems.

Abstract The hemagglutination inhibition (HI) test is the current gold standard for detecting antibodies to avian influenza virus (AIV). Enzyme-linked immunosorbent assays (ELISAs) have been explored for use in poultry and certain wild bird species because of high efficiency and lower cost. This study compared a commercial ELISA for detection of AIV subtype H5 antibodies with HI test of 572 serum samples from zoo birds. There was no significant difference between the results of the two tests when statistically compared by a McNemar χ2 test (P = 0.86) and assessment of κ (κ = 0.87). With a specificity of 94.2% (95% confidence interval [CI], 0.92–0.97), a sensitivity of 93.9% (95% CI, 0.91–0.97), and an excellent correlation between the two tests, this ELISA can be recommended as an alternative to the HI test for preliminary screening of zoo bird sera for antibodies to AIV subtype H5.


A new species of the mycoheterotrophic genus Lecanorchis Blume (Orchidaceae), L. moritae, is described from Amami-Oshima Island, Japan. It is most similar to L. suginoana but differs in having a transversely elliptic (slightly contracted at base) midlobe (vs. semiorbicular, not contracted at base), more triangular with almost entire margins (vs. relatively rounded, denticulate margins) and reddish apices (vs. somewhat whitish apices) and a lip with white and purple hairs (vs. white and lemon yellow hairs) and sparse unicellular papillae scattered on the disc (vs. dense unicellular papillae). An illustration and nuclear ribosomal internal transcribed spacer (nrITS) sequence (i.e., DNA barcode) of the new species are also provided.

ABSTRACT The Savannah River National Laboratory was requested to develop a Pu metal dissolution flowsheet at two reduced temperature ranges for implementation in the Savannah River Site H-Canyon facility. The dissolution and H2 generation rates during Pu metal dissolution were investigated using a dissolving solution at ambient temperature (20–30°C) and for an intermediate temperature of 50–60°C. The Pu metal dissolution rate measured at 57°C was approximately 20 times slower than at boiling (112–116°C). The dissolution rate at ambient temperature (24°C) was approximately 80 times slower than the dissolution rate at boiling. Hydrogen concentrations were less than detectable (<0.1 vol%).


The effect of the output impedance of peaking power amplifier (PA) on Doherty PAs (DPAs) is analyzed in this paper. In the design procedure of DPAs, the ideal case is that the output impedance of auxiliary PA is infinite at output power back-off (OPBO) level. However, it is almost impossible to realize this perfect condition in broadband DPAs. Therefore, when the output impedance of peaking path deviates from infinity, some potential effects on DPAs must be produced. In this paper, these effects are explained at the internal plane of transistors. The conclusion is that, at different normalized frequencies, there are different optimal impedance regions for the output impedance of peaking stage. This means that the noninfinite output impedances of peaking stage can enhance the performances of broadband DPAs so long as they are elaborately processed. A 1.65–2.7-GHz (48% bandwidth) broadband DPA is designed considering the effects of peaking PA. The experimental results show that this DPA obtains a drain efficiency of 41%–59.6% at 6-dB OPBO levels and a drain efficiency of 55.8%–72.2% at saturation power levels. The maximum output power across the entire operating band is 43.1–45.2 dBm with a gain of 9.0–10.2 dB. Furthermore, the designed DPA achieves an adjacent channel leakage ratio of −45.8 dBc with an output power of 36.1 dBm at 2.0 GHz after digital predistortion when it is excited by 5-MHz WCDMA signal with a peaking-to-average power ratio of 8.6 dB.


The Great Depression was a global phenomenon. Therefore, a comparison of the U.S. and Canadian experiences is helpful, because of the close economic ties the two countries share and because of significant differences between the two countries' financial structures. Yet, both countries experienced the Great Depression at roughly the same time and of comparable economic magnitude. The survey finds that a single cause is not responsible for this event. Nevertheless, what is striking is that despite differences in the two countries' financial structures, both countries suffered a tremendous slump. Institutional differences are insufficient to insulate a country from foreign shocks or their role in insufficiently understood. I conclude that the "ideology" of the Gold Standard was significant in overcoming the potential for institutional differences to cushion the blow of the Great Depression in Canada.


Constructions of pressure vessels like rocket launch vehicles, missiles, rocket propellant tanks, and filament wound pipes for civil and military applications are made out of high strength, high stiffness and light weight composites filaments. Filament winding techniques are used for fabrication of such cylinders and pipes. Many materials like glass fibers, carbon fibers and Kevlar fibers are used due to their good strength when it is subjected to internal pressure as well as external pressure. Basalt fibers are new materials that are fabricated from hard dense basalt rocks. Basalt fibers can be used in the place glass fibers due to their good mechanical behavior when subjected to internal pressure. Plates and beams generally resists bending loads and pipes and tube structures resists internal forces developed through internal and external pressure. This work concentrates the fabrication of filament wound pipes using filament wound techniques and the burst pressure test is carried out. In fuel tanks of rockets, If any one of the layer fails due to internal pressure, there will be mild leakage. For this reason it is mandatory to find out the ply by ply failure. The first ply failure of basalt filament wound pipes subjected to internal pressure is calculated using Finite element analysis. Then the stress and progressive failure analysis was carried out. Maximum stress failure criterion is used for the finite element analysis.

Pela reflects brotherhood of humanity (ukhuwah insaniyah) and Gandong reflects brotherhood established by family and national ties (ukhuwah wathaniyah wa an-nasab). The values of brotherhood in pela gandong culture are mutual help, providing a sense of security between others, understanding each other's characteristics


This paper presents a novel robotic stage for human balance disorder assessment. The proposed robot is composed of top and bottom plates which move perpendicular to each other in x- and y- directions. Both plates can be driven or controlled simultaneously or one at a time. Each of the drive systems for the plates utilize a BLDC motor, ball-screw, force sensor, and motor encoder, which enable various control strategies. Moreover, the force sensor is located between the ball-screw and the load, hence, the load reaction force can be directly measured. To conduct the balance assessment, a human (patient) stands on the top plate of the stage and the robot is driven by either force or position control, from which the force is measured directly by the force sensor. Then, the balance disorder assessment is done by observing the characteristics of the force measurements. This device provides a wider motion strokes which enable the examiner to obtain detailed balance disorder information as compared to the existing techniques. Experiments on both control and actual human balance test are carriedout to verify the effectiveness of the proposed device.


Stevens, P. S. (24 Irving Street, Arlington, Mass. 02174) 1974. Space, Architecture, and Biology. Syst. Zool. 22:405-408.-When he analyzes an existing biological form, the taxonomist seldom considers alternative forms that might have existed in its stead. Consequently, he does not benefit from the lesson learned by the architect-Lwhose business it is to consider alternative forms-that physical organization is largely determined by the properties of space. A few examples suffice to show that space also imposes order on the development of biological form. In a marvelously sweeping statement, the late Swiss architect Le Corbusier said that the first act of existence is the taking possession of space. At first glance, the statement may not seem particularly meaningful. For architects, familiarity has made it a truism. But for biologists, t-he statement may merit a second look. To make the usurpation of space the handmaiden of material existence encourages a view of the genesis of form that offers special rewards to those who search for fundamental principles of organization. Let us compare the attitudes of the biologist and the architect toward the development of form. In the simplest terms, the biologist, or at any rate the taxonomist, starts with the design solution-the mollusk, say, or the fern-and seeks to reconstruct its evolutionary development, to retrace the steps in the maturation of its design. The architect, on the other hand, starts with an empty building site and "chooses"-wit-hin the constraints of budget, materials, orientation, and so forth-the best possible building to erect on it. At each step in the design process, he attempts to select the happiest solution. The difference in approach between these two professionals is elucidated by the words of the Stigmatine Fathers: "Some people see things that are and say why? We dream of things that never were and say why not?" The first half of that epigram describes 'Mr. Stevens is the director of the Architectural Planning Office of the Harvard Medical Area, Boston, Massachusetts.-Editor. the practical biologist who considers the things that are. The second part describes the architect who drifts above the clouds dreaming of remote possibilities. Lest the biologist feel slighted, however, he has only to witness how quickly the dreaming architect comes down to earth upon discovering that the empty site permits the materialization of only a few of all the lovely things that never were. The realistic alternatives are inevitably fewer than the designer first imagines. The space at his disposal contains its own constraints, and those constraints dictate the organization of all the elements that can take possession of it. That lesson benefits the biologist as well. Proceeding as he does by way of analysis rather than synthesis, the biologist seldom receives the message as forcefully as the architect. But the general space that all things share contains constraints, and those constraints dictate the organization of the elements that can take possession of it. In biology as well as architecture, the possible configurations are strictly limited. The fact that space imposes constraints on nature's productions should be a great boon to the biologist. Organization need not be ascribed totally to biological operators, inductors, evocators, and regulators. Much of the regulation is imposed by the space in which the form resides. The reason why that "organizer" has been difficult to see is that it is everywhere you look. Biologists have revealed two ways in which space affects the form of things.

Background: The main cause of complications in diabetes mellitus is a condition of oxidative stress due to increased reactive oxygen species (ROS). The increase in ROS can be triggered by the increase in advanced glycation end-products (AGE), which binds to its receptor (RAGE). The result of increased ROS will lead to lipid peroxidation in cell membranes and induce particular increase in malondialdehyde (MDA).
Objectives: The objective of this study was to evaluate the benefits of physical exercise in preventing complications of the kidneys caused by hyperglycemia.
Method: This study was a pure experimental research with post-test only group design. Subjects were 10 male Sprague Dawley rats induced with 35 mg/kgdose of streptozotocin (STZ). The subjects were divided into two groups, i.e. the STZ group and STZ group with physical exercise. Physical exercise was given in 9 weeks using a treadmill, in 5 times/week frequency, moderate intensity, 0 degree of tilt, gradually increased speed and duration.
Result: Regular and measurable physical exercise can decrease the blood glucose level(0,048) and reduce the RAGE expression in glomerulus(0,003) but increase MDA level in kidney (0,767).
Conclusion: Regular and measurable physical exercise can decrease the blood glucose level and reduce the RAGE expression in glomerulus.

Abstract : During World War 11, American army officers who had spent their entire careers commanding at regimental level and below were suddenly called upon to lead armies and army groups against the foe in both Europe and the Pacific. Especially in the Pacific, this meant commanding large forces composed of air, land and sea elements. Although not 'without their share of problems these leaders were up to the challenge. How were they able to make the remarkable transition from commanding a brigade of 3000 soldiers to a field army of over 300,000 in a few brief years? What assignments, education, or training prepared them to fight in a joint and/or combined environment? What qualities and attributes made them effective operational commanders? The army officer of today faces much the same situation as his predecessor of the interwar period. Although there has been a flurry of interest in the operational level of war since 1982, the focus of the officer corps remains firmly fixed upon the tactical level, The vast bulk of an officer's career is spent in assignments at division and below.


According to the legend, witches were women with magical knowledge that with the use of herbs cured illnesses and performed spells. In 1639, the book "De Nuce Maga Beneventana" described how the place where the "witches" gathered was an area south of the city of Benevento in South Italy in a long and narrow gorge. This valley with high rock walls was called the "stretto di Barba". According to the legend, under a walnut tree in the "stretto di Barba", the Longobards were used to perform sacred rituals. To make the rituals more effective, the sounds were amplified by the narrow gorge with flat and parallel rock walls where the sound reflections generated echoing effects. The aim of this paper is to investigate the soundscape of the "stretto di Barba" and to investigate if it has the acoustic characteristics that create echoes and to confirm the legends about the Longobards' rituals. In situ measurements were carried out. Numerical simulations were carried out using the acoustic software Odeon. The paper shows that if a place where the Longobards carried out their rituals really existed, then the "stretto di Barba" had all the proper acoustic characteristics to create multiple sound reflections and echoes.According to the legend, witches were women with magical knowledge that with the use of herbs cured illnesses and performed spells.

In both the UK and in France, the rise of techno music was been linked with the consumption of ecstasy and perceived negatively. Techno events were forcibly cancelled, and premises closed down by police. This led to a new type of techno concert: the Rave. Raves were also rapidly targeted and banned. Techno artists and technicians responded by forming Collectives known as Sound Systems. These Sound Systems organised Free Parties – free and illegal raves – within which anarchist ideology developed, paving the way for a youth cultural movement. In France, the development of this movement in the second half of the 90s forced the State to respond: initially by passing repressive laws and then, when faced with the difficulty of enforcing such laws, by negotiating with the Collectives so that
Free Parties could continue to be held but with minimal public disorder.


This paper is concerned with model monitoring and quality control schemes, which are founded on a decision theoretic formulation. After identifying unacceptable weaknesses associated with Wald, sequential probability ratio test (SPRT) and Cuscore monitors, the Bayes decision monitor is developed. In particular, the paper focuses on what is termed a 'popular decision scheme' (PDS) for which the monitoring run loss functions are specified simply in terms of two indiff erence qualities. For most applications, the PDS results in forward cumulative sum tests of functions of the observations. For many exponential family applications, the PDS is equivalent to well-used SPRTs and Cusums. In particular, a neat interpretation of V-mask cusum chart settings is derived when simultaneously running two symmetric PDSs. However, apart from providing a decision theoretic basis for monitoring, sensible procedures occur in applications for which SPRTs and Cuscores are particularly unsatisfactory. Average run lengths (ARLs) are given for two special cases, and the inadequacy of the Wald and similar ARL approximations is revealed. Generalizations and applications to normal and dynamic linear models are discussed. The paper concludes by deriving conditions under which sequences of forward and backward sequential or Cusum chart tests are equivalent.


In this work, we generalize the recent sparse iterative covariance-based estimator (SPICE) by extending the problem formulation to allow for different norm constraints on the signal and noise parameters in the covariance model. The resulting extended SPICE algorithm offers the same benefits as the regular SPICE algorithm, including being hyper-parameter free, but the choice of norms allows further control of the sparsity in the resulting solution. We also show that the proposed extension is equivalent to solving a penalized regression problem, providing further insight into the differences between the extended and original SPICE formulations. The performance of the method is evaluated for different choices of norms, indicating the preferable performance of the extended formulation as compared to the original SPICE algorithm. Finally, we introduce two implementations of the proposed algorithm, one gridless formulating for the sinusoidal case, resulting in a semi-definite programming problem, and one grid-based, for which an efficient implementation is given.


In many industrial applications, the robot is required to perform a set of repetitive tasks without collision as quickly as possible to maximize productivity. It is essential to find an optimal sequence of collision-free motions to visit a set of repetitive tasks and determine the optimal robot configuration used to complete each task, which is formulated as the Robotic Task Sequencing Problem (RTSP). In this paper, we propose an approach based on a typical decoupling strategy to solve RTSP efficiently. Firstly, the task execution sequence is obtained by solving a TSP in task space and candidates of the optimal configuration for each task are selected from the collision-free configuration space according to the self-designed optimality value derived from the similarity to the initial configuration in configuration space. Then the optimal configuration for each task is determined by finding the shortest path in a graph that is constructed according to the task execution sequence and optimal configuration candidates. Finally, collision-free motion trajectories required for the robot to complete each task with the optimal configuration are generated by running a motion planning algorithm. Through a series of experiments, we show that our approach outperforms the state-of-the-art approaches when applied to the RTSP instances in a cluttered 3D environment, with up to 29.6% reduction in computation time while providing comparable performance.


Public transport is an important means of transportation for urban residents. In China, the government strongly advocates urban residents to travel by public transport. However, the unreasonable allocation of public transport resources and a large number of passengers result in in-bus congestion during the peak period, which will decrease the passenger satisfaction and increase the loss of passengers. Targeting on the issue, this paper provides a passenger satisfaction prediction method based on Driving time (PSP-DT) using Long Short-Term Memory (LSTM) network. First, the bus arrival and departure time are extracted by matching the bus GPS trajectory with the bus station data using the map matching method. Second, the historical driving time is captured from arrival time and departure time, and the future driving time is predicted by LSTM considering weather. Third, passenger satisfaction based on driving time is estimated by the proportion of overload and standard load. By using the 18 working days data of bus No. 14 and a total of 162,628 bus driving data records in Guangzhou city, China, our experimental results show that 1) the prediction model performs well and the average $\overline{M A P E}$ and $\overline{RMSE}$ is 5.57% and 11.40. 2) During the morning and evening peak period, the lowest passenger satisfaction of twenty stations is 45.78% and 71.86% separately.


The study investigated Academic and Environmental Stress as Predictors of Academic Achievement of Secondary School Students in Nsukka Education Zone of Enugu State, Nigeria. The need for the study came as a result of increasing rate of poor academic achievement of secondary school students in the study area to which the researchers sought to find solutions. It was guided by two research questions and two corresponding null hypotheses tested at 0.05 level of significance. The research design used for the study was correlation survey design. The population of the study comprised the entire four hundred and sixty secondary school students identify from cumulative record folder of SSII students who have performed poor in English Language and Mathematics in the study area. The entire population of 460 students were used as sample. In this case, there was no sample. This is because the number can be managed. The instrument for data collection were three sets of questionnaire titled "Academic Stress Questionnaire (ASQ)", "Environmental Stress Questionnaire (ESQ)"; and Academic Achievement Proforma (AAP)". ASQ and ESQ were properly validated by experts in test development and the internal consistency reliability indices of the items estimated at 0.83 and 0.85 respectively using cronbach alpha method. The data collected were analyzed using coefficient of determination (R2) for research questions, while linear regression was used in testing the hypotheses at <0.05 level of significance. The findings of the study revealed that academic stress predicts positively academic achievement of secondary school students. Also, the study found out that environmental stress predicts positively academic achievement of students. The findings also revealed that there is a significant relationship between academic stress and academic achievement of SSII students in Nsukka Education Zone of Enugu State, Nigeria. Based on the findings, it was recommended among others that secondary school guidance counsellors should organize seminars on academic and environmental stress on academic achievement of students to help improve academic achievement of students.


Block matching motion estimation techniques have been widely used in video coding applications.However,they also show their deficiency in the coherence of motion vectors and antinoise ability.This paper proposes a modified algorithm which can adopt any one of existing search algorithms and pays more attention to the correlation of neighboring blocks.It will be shown that the proposed algorithm is simple and significantly reduces the computational complexity.Simulation results also show that this algorithm improves the smoothness of the motion field,hence reducing the cost to code the motion vectors while keeping good performance comparable with the conventional block matching motion estimation algorithm.


Excitation functions of the reaction products B, C, N, O, F and Ne in the dissipative heavy ion collision of F-19+Al-27 have been measured at incident energies from 110.25 MeV to 118.75 MeV in step of 250 keV. The energy coherent widths F of the products are extracted by using the energy autocorrelation functions. Taking into account the properties of both the rotation and decay in an intermediate dinuclear system formed in the reaction, the Ericson statistical theory in nuclear reaction has been developed and the evolution process of the dinuclear system is discussed.


We have investigated the bias-voltage dependence of the phase-dependent differential resistance of a disordered T-shaped two-dimensional electron gas coupled to two superconducting terminals. The resistance oscillations first increase upon lowering the energy. For bias voltages below the Thouless energy, the resistance oscillations are suppressed and disappear almost completely at zero bias voltage. We find a qualitative agreement with the calculated reentrant behavior of the resistance and discuss quantitative deviations.


n engl j med 375;21 nejm.org November 24, 2016 2101 the threshold for minimal residual disease, and longer survival with inotuzumab ozogamicin than with standard care. More patients in the safety population underwent post-trial transplantation after receipt of inotuzumab ozogamicin than after standard care and before any follow-up induction treatment (45 of 139 patients [32%] vs. 14 of 120 [12%]). The median duration from the receipt of the last dose of therapy to transplantation was shorter with inotuzumab ozogamicin than with standard care (31.0 days [range, 9 to 135] vs. 54.0 days [range, 28 to 130]). Additional data, now available for the 326 patients who underwent randomization by January 2015, show that more patients in the expanded safety population underwent transplantation after receipt of inotuzumab ozogamicin than after standard care and before any follow-up induction treatment (71 of 164 patients [43%] vs. 18 of 143 [13%]). Among patients who received inotuzumab ozogamicin, 13 of 60 patients (22%) who underwent transplantation 2 months or less after receipt of the last dose and 2 of 11 (18%) who underwent transplantation more than 2 months after receipt of the last dose had veno-occlusive disease. The median duration from the receipt of the last dose of therapy to transplantation was again shorter with inotuzumab ozogamicin than with standard care (34.0 days [range, 9 to 135] vs. 55.5 days [28 to 188]). Notably, in a univariate analysis, the duration from the receipt of the last dose of therapy to transplantation was not a significant risk factor for veno-occlusive disease; multivariate analysis confirmed the use of a dualalkylator conditioning regimen as a significant risk factor.


The city of Ilion and its sanctuary of Athena Ilias are a good example of civic identity and regional culture in the Straits (Hellespont and Bosporus). This sanctuary, both civic and federal, was on the territory of the city of Ilion, but the Panathenaia festival was administrated by all the cities of the koinon of Athena Ilias. This association gathered cities of Troad and beyond, all the way to Chalkedon on the Bosporus. The study of the nature, organization, and ethnic and geographic composition of this koinon gives us precious information about the regional culture in the Straits.


The article deals with the issue of emergency management at the level of territorial self-government. The paper tries to outline the usage of the theory of system dynamics. We can use this theory for analysis of the municipality as the emergency management authority. The municipalities and regions are delegated by the Act on emergency management to planning, to organization and to control in the area of crisis management. These subjects are obliged to finance the control of crisis situations. Just this area is drawn in the model which uses the principles of system dynamics. This model outlines the basic interrelations among the partial elements of the system of financing.

Social ill and disciplinary problems among school students are becoming serious lately. It has become a topic of discussion for everyone. This problem has to be addressed wisely so that it leaves a good impact on students. We are accepted in the society when we have good discipline. In addition to that, religious knowledge is the basis for moulding the character of a Muslim. Practice is the action done based on the knowledge and experiences that one has. The combination of those elements produces a true Muslim. A study was carried out at secondary schools in the district of Tawau,
Sabah so as to identify the relationship between appreciation of religious values and
compliance to regulations and discipline in schools. The sample of this study was 617
secondary school students from four schools in the district of Tawau, Sabah. Random stratified sampling was used in this study. Questionnaires, consisting of respondents'
profile, level of religious knowledge and the level of appreciation of religious values, were distributed. Data were collected and analyzed using SPSS version 12.0. The focus of this study was to see the level of understanding and appreciation of the content of Islamic Education among the students. This study also sought to identify the relationship between the understanding of Islamic Education and the compliance of students towards the school rules. Descriptive analysis method and Pearson
Correlation test were used in this study. The findings indicated that respondents' understanding of religion was at the moderate level meanwhile the level of appreciation of religious values was low. On the other hand, findings from Pearson Correlation test showed that there was a significant relationship between the level of understanding of Islamic Education and the compliance of students towards the school rules. The relationship between both the variables was high and positive


Course management based on feedback system design principles to enhance student learning experiences is described in this paper. Structure, emphasis, projection, and review are interrelated in feedforward parallel, and feedback exercises. This management strategy for the design of courses has been tested and fine-tuned during several terms in undergraduate courses on circuits, control systems, and random signals. Materials and experiences from these three courses are presented to demonstrate key components.


The traditional application of the classical homogeneous nucleation theory (CNT) to the condensation in rapidly expanding flows involves the use of the steady‐state nucleation rate. Since this rate is derived under the assumption of both steady‐state and isobaric/isothermal conditions, the applicability of CNT to highly nonequilibrium environments may be questionable. In addition, the usual strategy of CNT — gas dynamics coupling violates the original nucleation theory even in the isothermal/isobaric environment. In this study, we consider condensation in jets freely expanding into a vacuum. Using the isentropic solution, we approximate the time‐dependent pressure and temperature in a given small volume of a gas that is moving along the jet axis with the flow velocity. Several possible strategies of CNT implementation are considered within this volume. It is shown that the terminal cluster distributions are strongly affected by the steady‐state assumption and that the original CNT rate equations should be...


This book begins with an essential background discussion of the many applications and drawbacks for paraxial beams, which is required in the treatment of the complex space theory of spatially localized electromagnetic waves. The author highlights that there is a need obtain exact full-wave solutions that reduce to the paraxial beams in the appropriate limit. Complex Space Source Theory of Spatially Localized Electromagnetic Waves treats the exact full-wave generalizations of all the basic types of paraxial beam solutions. These are developed by the use of Fourier and Bessel transform techniques and the complex space source theory of spatially localized electromagnetic waves is integrated as a branch of Fourier optics. Two major steps in the theory are described as: 1) the systematic derivation of the appropriate virtual source in the complex space that produces the required full wave from the paraxial beam solution; and 2) the determination of the actual secondary source in the physical space that is equivalent to the virtual source in the complex space. Complex Space Source Theory of Spatially Localized Electromagnetic Waves introduces and carefully explains original analytical techniques; includes a treatment of partially coherent and partially incoherent waves; provides treatment of the newly developing area of Airy beams and waves; develops complex space source theory as a branch of Fourier Optics.


In this paper, the structure and operation principle of a slice hybrid magnetic bearing (HMB) with two radial air-gaps are analyzed, and the mathematical model of radial suspension force is deduced. Then, the magnetic paths are analyzed, and the radial suspension force is calculated by finite element method. Finally, the experimental prototype HMB is designed and constructed, where waveforms of stable suspension and antiinterference experiment are tested. The theory analysis, simulation and experimental results have shown that the proposed slice HMB can achieve stable suspension.


A theoretical model for formation of light-induced gratings in organic photoisomers is presented. Using this model, dynamic behaviors of the light-induced gratings are studied theoretically for two different cases: in the first case, in addition to a CW laser generating the writing beams and the reading beam, a pulsed laser is used as an optical pump, in the second case, the writing beams are provided by a pulsed laser, and the reading beam comes from a CW laser. Agreement between experiment and theory is also demonstrated.


Milner's understanding of cooperation "begins from the premise that the state is not a unitary actor" (p. 10). Rather, it is conceptualized as a "polyarchy" (an unfortunate term given the potential for confusion with Robert Dahl's work), "composed of actors with varying preferences who share power over decision making" (p. 11). It is the structure of domestic politics-comprised of the preferences (or interests) of actors, as well as prevailing institutional arrangements and the information possessed by actors-that Milner contends will strongly shape the possible degree and form of international cooperation. Indeed, she suggests that domestic politics is more influential than international factors, and that domestic political explanations of cooperation are, thus, more appealing than ones dependent on the international system-such as those based on notions of "hegemonic stability." By ignoring domestic factors, Milner asserts, analysts-including realists -have tended to overestimate the occurrence of international cooperation. Interests, Institutions, and Information develops these arguments in two sections. The first part establishes a rational choice-based theoretical framework for examining international cooperation; the second presents a series of paired case studies in which cooperative agreements were concluded in one case and failed in the other. Such an explicitly comparative case analysis, linked to a more formal theoretical approach, represents an encouraging methodological development. Given the substantive and theoretical significance of Milner's subject matter, this methodology should have resulted in an excellent book, deserving a wide readership. Unfortunately, even though Interests, Institutions, and Information has much value, the promised book has not quite materialized. A number of factors account for this disappointing result, varying from minor to more fundamental deficiencies. At the more trivial end, several quibbles can be raised. For example, although the case studies are readable and interesting, Milner's knowledge of some of them appears rather superficial. As a result, those interested in the cases themselves should probably look elsewhere. More generally, Interests, Institutions, and Information would certainly have benefited from closer editorial supervision-to enhance the lucidity of the prose, and to eliminate the rather-too-frequent errors that mar the text. Neil Kinnock, for instance, would

An essential factor in the development and progression of chronic kidneydisease with the presence of oxaluria against a background of malabsorption syndromeis an increase in the intensity of free radical oxidation of lipids and proteins (mainly dueto aldehyde and ketondinitrophenylhydrazones of a neutral nature).


In this paper, we present a new method for optimizing knot positions for a multi-dimensional B-spline model. Using the results from from univariate polynomial approximation theory, spline approximation theory and multivariate tensor product theory, we develop the algorithm in three steps. First, we derive a local upper bound for the L∞ error in a multivariate B-spline tensor product approximation over a span. Second, we use this result to bound the approximation error for a multi-dimensional B-spline tensor product approximation. Third, we developed two knot position optimization methods based on the minimization of two global approximation errors: L∞ global error and L2 global error. We test our method with 2D surface fitting experiments using B-spline models defined in both 2D Cartesian and polar coordinates. Simulation results demonstrate that the optimized knots can fit a surface more accurately than fixed uniformly spaced knots.


We report on the fabrication and characterization of p-π-n GaN ultraviolet detectors. The peak responsivity at ∼363  nm is measured to be 0.1 A/W in the photovoltaic mode, and 0.14 A/W with a bias of −15 V. Speed measurements have shown the photoresponse to be RC-limited with the response time decreasing from 17.4 ns at zero bias to 10.3 ns at −6 V bias. For a 200×200 μ m2 device, we measure the dark current to be 2.7 pA at −3 V bias, and a noise density of less than 10−25 A2/Hz, the noise floor of the measurement. Extrapolating the noise data taken at higher reverse biases, we estimate the noise equivalent power to be 6.6×10−15 W/Hz1/2.

Antibiotics in water have attracted increasing attention due to their potential threat to aquatic ecosystems and public health. Most previous studies have focused on heavily polluted environments, while ignoring urbanized rivers with high population density. Taking Suzhou Creek in Shanghai as an example, this study attempted to explore the antibiotic pollution characteristics of typical urbanized rivers. Further, it screened out priority antibiotics so as to provide reference for the regular monitoring of antibiotics in urban surface water in the study's later stage. Four classes of 27 antibiotics in surface water samples and sediment samples were detected and analyzed by SPE-UPLC-MS/MS under both wet season and dry season. Results demonstrate that the total amount of antibiotics detected reached 1936.9 ng/L and 337.3 ng/g in water samples and sediment samples, respectively. Through Pearson correlation analysis, it can be shown that there is a very significant correlation between a variety of antibiotics in water and sediment. The results of ecological risk assessment based on risk quotient (RQ) show that certain antibiotics presented high and medium risk to the surrounding ecosystem. Finally, the priority antibiotics selected by optimized priority screening method were EM, SPD, CLR and RTM. Therefore, we have proven that the antibiotics being discharged in urbanized rivers show different types of antibiotics, while presenting a toxicological risk to certain species.

BKAIN, lacking as it does significant amounts of alcohol dehydrogenase. [EC 184.108.40.206] ( R A S K I N & SOKOLOtF. 1972). seems relatively immune (VELOSO er d., 1972) from the major metabolic disturbances that have come to be associated with ethanol metabolism in liver (KKEBS, 1968: WII.LIAMSON PI a/.. 1969; Lrsu~os. 1970: VFECH of d., 1072). There is evidence. however, that acetaldehyde, the bloodborne product of hepatic ethanol oxidation. can affect some aspects of brain metabolism. In particular, several studics have suggested that ethanol (presumably \ia its metabolic product acetaldehyde) can produce significant decreases in the concentrations of CoA i n brain as well as liver (AMMON et a/.. 1967: AMWOK P I u/.. 1969: RAWAT. 1074). Such ohscrvations are of interest especially i n brain since CoA and acetyl-CoA arc inbolved in the synthcsis of the neurotransmitter acctyl-cholinc through the reaction of choline acetyltransferase [EC 2.3.

A test for resistance to gas-abrasive wear of several variants of multilayer vacuum-plasma coatings based on titanium and vanadium nitrides of various thicknesses and number of layers was carried out. Erosion curves are given, areas of accelerated wear are determined, and comparative values of wear resistance are calculated. Based on the conducted microscopic studies, a mechanism of layer-by-layer wear of the studied multilayer coatings is proposed. It is shown that due to the creation of a special layered coating structure, including the alternation of highly hard nitride and relatively softer Ti and V layers, the resistance to gas-abrasive wear of parts of gas turbine engines made of titanium alloys is greatly increased.

The Green function approach to the theory of the interacting photon-electron-phonon system is presented. The method of Legendre transforms is used to derive the Dyson equations for the photon and phonon Green functions, as well as the Bethe-Salpeter equation for the two-particle electron-hole Green function. Knowledge of those Green functions provide the excitation energies of the quasiparticles (polaritons) formed by coupling of excitons with photons and phonons. Examination of the poles of the two-particle electron-hole Green function leads to an equation for the Bethe-Salpeter amplitudes, as well as to a microscopic derivation of the Maxwell equations taking account of the local-field effects. A normalisation condition for the Bethe-Salpeter amplitudes is derived. In the limit of an instantaneous electron-phonon interaction the equations for determining the renormalised phonon frequencies are obtained, as well as the sum rule for them, similar to the Lyddane-Sachs-Teller relation. In order to define a dielectric function which does not depend on reciprocal lattice vectors (crystal optics approximation), the special eigenvalue problem is treated by successive integrations, first over rapidly varying photon fields and then over slowly varying photon variables.

Case based reasoning (CBR) has come to be recognized as one of the standard approaches in the context of data mining and knowledge discovery to determine the best match of a new case among the currently defined cases in the database. It is well known that CBR is highly sensitive to the attribute space in which such reasoning is carried out. A priori assessment of the attributes to determine the relevancy and effectiveness of the potential attributes is often carried out using feature selection techniques adapted from the pattern recognition world. It would be beneficial to be able to elucidate the significance of the attributes so selected on the decisions made by the CBR process on the individual cases. Towards this end, the concept of elucidation proposed recently in the context of information fusion systems is adapted here to develop a methodology for attribute significance assessment. The methodology is illustrated using a couple of well-known data sets available in the literature and/or on the Internet.


A variable frequency oscillator circuit adapted for sta bilization of its free-running frequency comprises a first signal synthesizing circuit, first voltage-controlled os cillator, a phase-locked loop and reference signal gener ator, the phase-locked loop consisting of a second signal synthesizing circuit, second voltage-controlled oscilla tor, phase comparator and low-pass filter. The first and second signal synthesizing circuits have the same char acteristics, and the first and second voltage-controlled oscillators have the same characteristics. The reference signal and output of the second voltage-controlled os cillator are input to the phase comparator. The compar ator output is applied to the first and second signal synthesizing circuits. An external signal is applied to the first signal synthesizing circuit, and the output of the first voltage-controlled oscillator acts as the output of the variable frequency oscillator circuit. The principles are applied to reading data pulses from a floppy disk.


"The popularity of digital money due to the high capabilities of digital technologies, data transmission, makes it possible to carry out fast transactions and store capital in the form of electronic, virtual funds. Mining technology allows you to mine cryptocurrencies (bitcoin, Namecoin, etc.) in real time using a large number of video cards for parallel calculations of soda (hashes), while a large amount of electricity is consumed. The boom of mining technology occurred in 2009-2015, which caused a sharp increase in electricity consumption and insufficient capacity for the development of other sectors of the economy In Kazakhstan due to the low cost of electricity, there was an increase in the number of mining farms, and therefore there were several blackouts. As a rule, a mining farm does not belong to consumers of the 1st category, for whom switching to other feeders takes place, the elimination of accidents has recently taken quite a long time and the equipment stops, causes overheating and failure of video cards, moreover, the calculation process itself is interrupted, the warranty functioning of the equipment is not provided. The presented article discusses the methodology of organizing the backup power supply of a mining farm, the selection and justification of the necessary equipment and automation.

School classroom evaluation methods using student achievement results are currently a significant topic of investigation in the educational accountability arena. The objective of this study was to identify effective and ineffective elementary school classrooms based on student and teacher characteristics. In this conceptualization, teacher's effectiveness in reading and mathematics was associated with exceptional measured performance above or below that which would be expected from students across the district. The analyses were conducted on 416 third grade classrooms (year 1) and 391 third grade classrooms (year 2) from 87 elementary schools in the Jefferson County Public Schools in Louisville, Kentucky. In all there were 276 teachers in each year and 6,692 students the first year and 6,522 the second year. The findings of the multiple regressions indicate that previous test score was the strongest predictor of student achievement. Student characteristics and teacher characteristics also significantly contributed to the explained variance of the regression model, yet not at the same magnitude as previous test scores. Future research efforts include the study of best practices of high performing teachers identified by the findings of the residual analysis. (Contains 3 tables and 50 references.)

For cluster router, traditional model of routing table synchronization has two shortcomings that are long time synchronization and unbalanced load among all cards. So the routing synchronization model need be improved in cluster router. After analyzing the current synchronization model and the architecture of cluster router, KPMH (k-path multi-hop) distributed routing synchronization model is proposed in this paper. We deduce the number of cards in routing synchronization in any period of k-path distribution, and analyze the load balance degree of cards. Based on the analyse, it is concluded that 2-path is best for current architecture of cluster router. And then the algorithm for 2-path routing distribution is designed. Performance evaluation and experiment show that KPMH model is much better than traditional model.


beamshapes is an open-source Python package that implements various directivity patternsfor sound sources. While there is an abundance of published directivity patterns in the literature- their computational implementations often remain as in-house scripts in proprietarylanguages. beamshapes overcomes this gap, and provides acousticians and bioacousticianseasily accessible implementations of sound source directivities.

PURPOSE: A method and a device for electronic device control are provided not to use a stylus and a button at the same time, thereby improving the availability of an electronic device. CONSTITUTION: A touch screen(110) is operated with a stylus(130). A button(120) operates a device. A controller(140) determines whether the stylus is removed from the device. If the stylus is removed from the device, the controller inactivates a function of the button and activates the touch screen. If the stylus is inserted into the device, the controller inactivates the touch screen and the button activates.


Reuters reports have become an accepted tool for empirical studies analyzing informationa l asymmetries in exchange rate markets. This paper tests the accuracy of the Reuters announcements for Swiss interventions. The evidence finds that the Reuters announcements are not concentrated just after the first intervention transaction as is assumed in empirical studies. The variance of the prediction error is measured in hours and not in minutes. A further assumption that the Reuters announcement always falls after the first actual transaction is found to be violated. At a minimum, the new empirical results question the accuracy of Reuters reports for small countries.


The importance of credit market imperfections for investment behavior is analyzed using Swedish firm level data. Adjustment and agency costs are included in the neoclassical theory of optimal financial and investment decisions for firms. In order to model the possible occurrence of agency costs of debt, and credit constraints, the behavior of banks is reviewed in the light of the theory of imperfect information. The econometric results indicate that investments are a¤ected by both adjustment and agency costs, but not by credit constraints. Moreover, it is also shown that financial decisions are a¤ected by agency costs. Finally, there is evidence of credit constraints prior to financial deregulation, but not specifically for small or independent firms.


Objective: To describe the emergency ambulatory dental care profile in a Family Health Center (CESFAM) in Valdivia. Materials and methods: Descriptive study conducted between April and July 2019 in the Emergency Dental Service CESFAM Dr. Jorge Sabat of Valdivia. Consecutive care was recorded for patients over 18 years of age. The following information was obtained from a data collection sheet: area of origin, history of previous emergency extraction, educational level, reason for consultation, and, if applicable, reason for extraction. In addition, through the "Emergency Care Data" form, sex, age, diagnosis, treatment, and, if applicable, extracted tooth were recorded. Results: 947 visits were recorded without duplication. In distribution by sex, 53.8% corresponded to women. The most frequent age group was adults (56.6%). The urban population corresponded to 90.8%. High school education was the most common with 37.6%. The main reason for consultation was pain (46.6%). GES diagnoses reached 37.7%. The most prevalent pathology was chronic periodontitis (35.9%), and the most performed treatment was exodontia (69.8%). Molars were the most extracted teeth (59.2%), and users with a history of previous emergency extraction corresponded to 62.7%. Conclusions: The general characteristics of the population revealed a deficit in oral health, where most of the participants consulted for pain in advanced stages of their diseases, undergoing mainly dental extractions as treatment. In general, the results are in line with national health studies and previous scientific literature, where the demand for attention is preferably from adults, primarily women belonging to urban areas, with complete secondary education.

Background: Oligohydramnios is a condition where the liquor amnii is deficient in amount to the extent of less than 200ml at term. Maternal complications can be prolonged labor due to inertia, increased operative interference. Methods: The present hospital based study was conducted in the department of obstetrics and gynaecology, East Point hospital, Bidrahalli, Bangalore, Karnataka, India. Duration of the study was for 6 months from November 2015 to April 2016. All pregnant women of gestational age >37 weeks attending the outpatient department were subjected to routine ultrasound examination. Results: Out of the total 410 pregnant women of gestational age >37 weeks in the study duration, the incidence of oligohydramnios was found to be 14% (n=58). 36 patients (62%) underwent lower segment caesarean section with fetal distress being most common indication for it. Incidence of low birth weight (<2.5 kg) was seen in 22 newborns (38.6%). One fourth of them had Apgar score less than 7 at 1 minute and 10 babies had less than 7 score at 5 minutes.  Neonatal intensive care unit (NICU) was required in 23 newborns (40%). Conclusions: A higher incidence of oligohydramnios was seen in the present study with increased maternal and perinatal complications associated with it.


The goal of the present work deals with the analysis the propagation of shear horizontal (SH) and Lamb waves in piezoelectric sandwich structures. For both kinds of wave, the exact solutions are obtained using the formulation of state vector combined with the method of surface local impedance and the technique of the global matrix. The spectra of dispersion, the asymptotic behaviours as well as the profiles across the thickness of the composite structures are numerically obtained. The surface (Bleustein-Guylaev and piezoelectric Rayleigh) and interface (Maerfeld-Tournois and piezoelectric Stoneley) waves obtained at high frequency are examined and discussed.


Molecular dynamics computer simulation has been performed in order to excite solitons in the two-dimensional mass-spring square-lattice model crystals. Central forces were considered between the nearest neighbor atoms in the crystal, and a lattice anharmonic potential up to the fourth order was taken into account. An input pulse displacement was given to the atomic rows in the crystal and the displacements of all the atoms were computed. When the applied input pulse was large, multiple solitons were produced. Collisions of the solitons with homogeneous and inhomogeneous rows of mass defects were simulated in order to investigate the characteristics of the defect-soliton interaction in the two-dimensional crystal. Collisions of solitons and phonons with a single mass defect were also simulated in order to investigate the differences in the characteristics of the two kinds of excitations.


Si-C-O ceramics were prepared by the interchange reaction of methyltriethoxysilane (MTES) with 1,4-butanediol (BD) and the subsequent pyrolysis. The structures of gels before and after pyrolysis were analyzed by NMR and IR. Carbon-13 CP/MAS NMR spectrum of the gel indicated the interchange reaction with the ethoxy groups of precursor, MTES. Silicon-29 MAS NMR spectra of the pyrolyzed gel revealed that SiC 2 O 2 and SiC 4 units existed upon higher temperature heat treatment. The cleavage of BD and the formation of free carbon phase in the pyrolyzed products were certified through TG-MS and 13 C MAS NMR. 29 Si MAS NMR, IR and XRD indicated the reaction of the free carbon with silica to form β-SiC above 1300°C.


The importance of load demand variation, when analysing energy and environmental impact of residential energy use, is increasing. Load demand in residential houses is a significant contributor to peak load problems experienced by utilities. The knowledge about demand variation in households is limited as well as the use of methodologies to analyse the demand is. Many utilities have recently installed interval (hourly) metering at their residential customers. The availability of this data is a big step forward, however, our experience show that the utilities use this data only to a limited extent, mostly for billing purposes only. This study aims to discuss the ways and benefits of using this valuable end-use data. There are several established load analysis tools, such as load curve, typical load curve, load duration curve, load factor, superposition factor, etc., which utilities could apply and develop. Among other benefits, the hourly load data analysis can provide the detailed characteristics of load demand in households, define the consumption patterns and can help to identify the main contributors to the utility peaks. This information is essential when developing new energy services, appropriate pricing, load management strategies and demand response programs. This paper analyses strengths and weaknesses of different analysis tools, the knowledge they could give, how applicable they are and what value they could have for the utility and the customer. The study is exemplified with ten "real world" cases in Southern Sweden, where the households with electric space heating and hot water systems are analysed. (Less)


Fermented foods such as Tempe represent a technological alternative for a great variety of legumes and combination of them to improve their nutritional quality and to obtain edible products with palatable sensorial characteristics. The chemical composition, carbohydrate fraction and nitrogenous constituents were investigated for individual different legumes, i.e. faba bean; lupine, chickpea; peas and their mixture before and after fermentation by Rhizopus oligosporus. Tempe had a higher (P < 0.05) protein and fibre content compared with legume mixtures before fermentation, while it had a lower fat, ash and carbohydrate contents. Also, reducing and non-reducing sugars, stachyose as well as raffinose were reduced after fermentation of legume mixtures. A significant reduction was observed in non-protein nitrogen and protein nitrogen, while total nitrogen and true protein were increased.


ABSTRACT This qualitative study explores three important and understudied areas of drug court research (e.g., women, opioid use disorder, and medication-assisted treatment [MAT]). The research question for this study is: What are women's thoughts, opinions, and experiences in drug court, in regard to the quality of treatment they received for their opioid use disorders and to the use of MAT in drug court programming to treat opioid use disorders? To answer the research question, data from female drug court participants (n = 14) were collected through a focus group methodology. Four themes emerged from the analysis: (1) Women had more positive views toward the use of extended-release injectable naltrexone, as compared to methadone and buprenorphine; (2) Women reported fears about using MAT to treat their opioid use disorders because they felt it could negatively impact their housing, where they were able to receive substance use disorder and mental health treatment, and their ability to maintain custody of their children; (3) Women reported histories of oppression, mainly trauma, and shared that, in some situations, they were not comfortable disclosing they were using or considering using MAT because of further oppressions they may experience; and (4) Women reported that the use of a non-adversarial approach by the judge, consistent with key component two of the drug court model, helped minimize their concerns related to the use of MAT and gave them a safe place during status hearings to discuss their opioid use disorder treatment and recovery. Implications for drug court practice and criminal justice reform are discussed, such as promoting access to housing and treatment for women who use MAT to treat their opioid use disorders and creating safe, anti-oppressive environments to promote recovery for female participants.


The gel content of photovoltaic module encapsulation Ethylene-vinyl acetate (EVA) is usually measured by the Soxhlet extraction method. Due to the destructive sample preparation, long turnaround times, hazardous solvents and the limited precision of results, an alternative crosslinking determination technique for the in-line process control is needed.The general capability of Raman spectroscopy as cross-linking determination method was investigated.EVA foils from two different manufactures were cured to different cross-linking degrees. Solvent extraction was used as reference technique. For the Raman spectroscopic investigation of the degree of cross-linking, residual peroxide peaks from the cross-linking agent in EVA were utilized. The intensity of the peroxide peaks appeared to be inversely correlated to the gel content.


Gene regulatory networks (GRNs) are complex networks that capture multi-level regulatory events between one or more regulatory macromolecules, such as transcription factors (TFs), and their target genes. Advancements in screening technologies such as enhanced yeast-one-hybrid screens have allowed for high throughput determination of GRNs. However, visualization of GRNs in Arabidopsis has been limited to ad hoc networks and are not interactive. Here, we describe the Arabidopsis GEne Network Tool (AGENT) that houses curated GRNs and provides tools to visualize and explore them. AGENT features include expression overlays, subnetwork motif scanning, and network analysis. We show how to use AGENT's multiple built-in tools to identify key genes that are involved in flowering and seed development along with identifying temporal multi-TF control of a key transporter in nitrate signaling. AGENT can be accessed at https://bar.utoronto.ca/AGENT.


In this article, the author empirically examines the impact of long-term client relationships on the performance of business service firms. On the basis of the information contained in the Compustat and Compact Disclosure sets of databases, he finds that, over the long run, relationship-oriented business service firms achieve higher returns on their investments than do transaction-oriented firms. Importantly, the findings suggest that, unlike relationship-oriented suppliers of business goods such as component parts, long-term client relationships do not improve the productivity of relationship-oriented service firms. However, such relationships help business service firms to resist price pressures from their customers and add more value to their services over time.


In the historical research on Sara Baartman, best known as the "Hottentot Venus," references to and discussions of her autopsy report by Georges Cuvier have been based on the original French text, "Extrait d'observations faites sur le cadavre d'une femme connue à Paris et à Londres sous le nom de Vénus Hottentotte," published in 1817. For scholars, students and the general public interested in the life of Baartman, an English translation of the autopsy report, with an introduction and a commentary, make an important contribution to Baartman's biography. Additionally, the project contributes to the history of medicine and, expressly, that of autopsy in the post-Enlightenment age of the First French Empire.


The article analyzes the vulnerability asso - ciated with social conflicts, taking as a case the state of Oaxaca. The reported data indicate the importance of institutional contexts in the configuration of a feedback loop between conflict and social vulne - rability, and are of analytical relevance in studies on human well-being. The data also contribute to the clarification and concep - tual expansion of vulnerability, recovering its semantic link with risk and with the response capacity of populations. These results are socially relevant at a time when the indicators of conflict and violence are on rise in different regions of the country. The study used a mixed method that combined the content analysis of just over three thou - sand newspaper and official sources, and a network analysis.

Using the temperature or temperature difference of the cooling source side to control the water flowrate of the primary pump system is considered as an effective energy-saving technology.In this paper,the influences of this technology on HVAC system were discussed from both the theoretical study and the case analysis.It was pointed out that the contradictions between the efficient operation and security services could not be effectively solved by this technology.Because of the instability properties,the technology was not a perfect control strategy.In fact,the energy-saving of HVAC system was benefit from the improvement of the original system,but not the real-time control of the water flowrate.


At ~20 ka bp, lakes Yehuin, Chepelmut and Fagnano constituted a single, large water body in the central part of Isla Grande de Tierra del Fuego (southernmost Patagonia). The evolutionary history of this lake, known as 'Palaeolago Fueguino', was probably controlled by the advances, stillstands and retreats of the 'Fagnano Palaeoglacier', an outlet glacier that flowed eastward from the Darwin Cordillera ice sheet. A detailed analysis of high‐resolution seismic reflection profiles acquired within the three lakes has allowed the identification and correlation of seven unconformities within the lacustrine sedimentary infill, three seismostratigraphic sequences in Lago Fagnano and four in Lago Yehuin. A seismic stratigraphic correlation between these sequences suggests that these basins formerly constituted a single, large lacustrine body. A lake‐level curve of the evolutionary stages of each lake, derived from the seismostratigraphic analysis of the sedimentary infill is proposed here, representing a 17.5 ka‐long record. It was further integrated with the glacial record of the advances and retreats of the Fagnano Palaeoglacier. This study has implications for interpreting the sedimentary history of lake basins in glaciated mountain ranges.
