Emotion management is a cross-over study of psychology and management and is the process of perception,control and adjustment for individuals and groups.As a new orientation of psychological researches,evolutionary psychology discusses emotions' adaptive values gained from the survival in the perspective of racial evolution,which shows that positive emotions and negative emotions in the process of evolution have different functions for individuals.Evolutionary psychology gives new enlightenments for emotion management: firstyly,adjust the cognition and negative emotions are a self-protection behavior of humans;secondly,nature is the most primitive parent of ours and getting close to nature is helpful for us to relax our minds and bodies;thirdly,search for the breakthrough from the negative emotions.


Introduction State-of-the-art automatic speech recognition (ASR) systems continue to improve, and yet there remain many tasks for which the technology is inadequate. The core acoustic operation has essentially remained the same for decades: a single feature vector (derived from the power spectral envelope over a 20-30 ms window, stepped forward by ~10 ms per frame) is compared to a set of distributions derived from training data for an inventory of sub-word units (usually some variant of phones). While many systems also incorporate time derivatives [Furui, 1986] and/or projections from 5 or more frames to a lower dimension [Hunt & Lefebvre 1989, Haeb-Umbach et al 1994], the fundamental character of the acoustic features has remained quite similar. We believe that this limited perspective is a key weakness in speech recognizers. Under good conditions, human phone error rate for nonsense syllables has been estimated to be as low as 1.5% [Allen 1994], as compared with rates that are over an order of magnitude higher for the best Renals 1994]. In this light, our best current recognizers appear half-deaf, only making up for this deficiency by incorporating strong domain constraints. To develop generally applicable and useful recognition techniques, we must overcome the limitations of current acoustic processing. Interestingly, even human phonetic categorization is poor for extremely short segments (e.g., <100 ms), suggesting that analysis of longer time regions is somehow essential to the task. This is supported by information theoretic analysis showing discriminative dependence conditional on underlying phones, between features separated in time by up to several hundred milliseconds In mid 2002, we began working on a DARPA-sponsored project known as the " Novel Approaches " component of the Effective Affordable Reusable Speech-to-text (EARS) program. The fundamental goal of this multi-site effort was to " push " the spectral envelope away from its role as the sole source of acoustic information incorporated by the statistical models of modern speech recognition systems, particularly in the context of the conversational telephone speech recognition task. This ultimately would require both a revamping of the acoustical feature extraction and a fresh look at the incorporation of these features into statistical models representing speech. So far, much of our effort has gone towards the design of new features, and experimentation with their incorporation in a modern speech-to-text system. The new features have already provided significant improvements in such a system in the 2004 NIST evaluation of recognizers of …

Homocysteine (Hcy) is a sulfur-containing nonprotein amino acid derived from the metabolism of methionine. Plasma Hcy is an independent risk factor for atherosclerosis (1)(2)(3)(4)(5).

The cyclic internal lactone form of Hcy, homocysteine thiolactone, may be the critical molecular form in the pathogenesis of atherosclerosis. In cultured cells, homocysteine thiolactone is synthesized through the reaction of methionyl-tRNA synthase (6)(7). This enzyme reacts with free amino groups of proteins to produce protein-bound homocystamide (7)(8)(9). The toxicity of homocysteinylation to the cell has been demonstrated in both in vitro and in vivo experiments. Lysyl oxidase, which catalyzes the posttranslational modification essential to the pathogenesis of connective tissue matrices, is irreversibly inactivated by homocysteine thiolactone (10).

Homocysteinylation increases the internalization of LDL by macrophages (11). Furthermore, homocysteinylated LDL elicits an autoimmune response (12). Homocysteine thiolactone hydrolase is present in human plasma and is identical to paraoxonase (13). Homocysteine thiolactone hydrolase may hydrolyze homocysteine thiolactone to Hcy and thereby prevent the homocysteinylation of proteins. In the absence of a suitable assay system for homocysteine thiolactone, however, no detailed study is available on homocysteine thiolactone or Hcy-related proteins. We have developed and evaluated an assay system for measuring protein-bound homocystamide in plasma and used it in samples from healthy adults and hemodialysis patients. Here we report the results of that study.

We obtained plasma samples from 20 healthy volunteers (12 males, 8 females; age range, 29–38 years) and 15 nondiabetic hemodialysis patients [7 males and 8 females; mean (SD) age, 49 (7) years] treated at the Suiyukai Clinic (Nara, Japan) after receiving their informed consent for this study. The patients were on hemodialysis using bicarbonate dialysate with systemic heparinization two or three times week a week. Blood was collected by …

In Wireless Sensor Networks (WSN), is used in many applications. Numbers of sensor nodes are deployed to gather the data from environment and process over it. During the formation of WSN main issue which comes under consideration is battery life of the sensor nodes. Once the sensor nodes deployed in sensor network, there maintains becomes difficult. To save the energy of sensor nodes we allow the mobile sink to move in the field and gather the data from the sensor nodes. In this paper we use mobile sink to gather the data from sensor nodes to conserve the battery life of network. Again there is a chance of creation of loopholes during the data gathering process. There is a need to detect the loopholes and to correct them. In this paper we use contki algorithm to find loopholes and remove them from the network.


We offer a lattice-theoretic account of the problem of dynamic slicing for pi-calculus, building on prior work in the sequential setting. For any particular run of a concurrent program, we exhibit a
Galois connection relating forward and backward slices of the initial and terminal configurations. We prove that, up to lattice isomorphism, the same Galois connection arises for any causally
equivalent execution, allowing an efficient concurrent implementation of slicing via a standard interleaving semantics. Our approach has been formalised in the dependently-typed programming language Agda.


This work focuses on the development of a plasma-based electroacoustic transducer for active noise control applications. The transducer is based on the atmospheric corona discharge in a wire-to-mesh geometry. The main motiva-tion for plasma technology is its simple robust design and absence of moving parts in the actuator, which could be advantageous when used in harsh environments. We char-acterise the corona discharge as an electroacoustic source. Further, we describe the active impedance control strategy for sound absorption by means of this type of discharge. The system is implemented experimentally in an impedance tube under normal sound incidence. The achieved sound absorption demonstrates the potential of the corona discharge actuators for use in active noise control systems, as an alternative to conventional electrody-namic transducers.

The control group shows more leakage in both the coronal and apical margins. Interpretation & Conclusion: Under the conditions of this in vitro study: 1) At the coronal margin, the preparations treated with Xeno V showed significantly less leakage than the other groups. 2) At the apical margin, the preparations treated with Clearfil S 3 Bond revealed significantly less leakage


Most English teachers nowadays recognize the necessity of teaching vocabulary in context. By context we understand not only the immediate semantic environment of any given lexical item, but the whole text surrounding (co-text), as well as the situation in which the discourse is produced (context). By bringing a discourse dimension into vocabulary teaching, we do not pretend to substitute neither traditional nor more recent communicative approaches. On the contrary, our challenge is to combine already existing approaches in teaching lexis with a discourse-oriented one. Our research is based mainly on the latest developments of Text Linguistics and Discourse Analysis in the field of lexical cohesion: studying vocabulary above sentence level. We propose that lexical cohesion as a significant feature of textuality could be successfully exploited by language teachers. By introducing vocabulary work on a discourse level, we pretend to provide language students with meaningful, controlled practice of vocabulary, as well as give them a chance to improve their text-creating and decoding abilities in a wide variety of contexts.

This article provides an introduction and overview of meditation practice, theory, and research. The models of human nature and consciousness from the meditative traditions are compared with traditional Western psychological models, and the former are suggested to encompass a wider range of states of consciousness and psychological well-being. The various models and mechanisms, psychological and physiological, Eastern and Western, that have been advanced to account for the effects of meditation are reviewed. Meditation practice is discussed both as a self-regulation strategy for specific psychotherapeutic and psychophysiological aims and as a discipline for deep self-exploration and transformation. When used for intensive self-exploration, meditation is best viewed as one component of a process demanding and producing a thoroughgoing transformation of all aspects of life and thought. The progression of experiences, insights, and states of consciousness that tend to emerge with intensive insight meditation are descibed, as are the author's initial experiences. The research literature on the effects and therapeutic applications of meditation is reviewed. We know the outer world of sensations and actions, but our inner world of thoughts and feelings we know very little. The primary purpose of meditation is to become conscious of and familiar with our inner life. The ultimate purpose is to reach the source of life and consciousness. Skill in meditation affects deeply our character. We are slaves to what we do not know; of what we know we are masters. Whatever vice or weakness in ourselves we discover and understand its courses and its workings, we overcome it by the very knowing; the unconscious dissolves when brought into the conscious [Sri Nisargadatta Maharaj, 1973, p. 15].


A novel single-switch three-level (TL) converter is proposed for dimmable LED lighting. Compared with standard TL converters, the proposed topology not only maintains the advantage of using a lower voltage rating power switch that is rated half the input voltage, but also eliminates one active switch and its associated driving circuit. Moreover, it can naturally solve the voltage stress imbalance issue because of the resonant flying capacitor. The operation principle and dimming scheme of the proposed TL converters have been described. A prototype of 46-W dimmable LED driving converter has been implemented to verify the designs and analyses. The experimental result shows that single-switch TL buck converter can regulate the LED current from zero to the desired 1 A with fast slew rate. A peak efficiency of 98% was achieved with 400 kHz switching frequency.

The efficacy of different aqueous dilutions of crude seed extract of Millettia ferruginea (Hochst.) Baker (1, 3, 5 and 10%) was evaluated under field conditions in terms of the level of damage and yield loss of maize caused by the maize stemborer Busseola fusca (Fuller) in Hawassa, southern Ethiopia. The insecticide lambda-cyhalothrin 5EC., applied at a rate of 16g active ingredient/hectare, was used as the reference product. The experiment was carried out in a randomized complete block design with four replications. The maize variety A511 was planted in individual plots of 60 m2. Data on stand count, leaf infestation, bored stem and dead heart were collected weekly. Plots sprayed with the 5% concentration of Millettia showed low levels of damage (9–11% leaf infestation, 0.4% dead heart, 14–17% bored stem and <0.2% bored ear), compared with plots sprayed with lambda-cyhalothrin. The treatments with 1 and 3% concentrations of Millettia were inferior to those with lambda-cyhalothrin and 5 and 10% concentrations of Millettia. In contrast, the treatment with the 10% concentration of Millettia led to the death of plants, thereby lowering the yield. About 80% of the total length of individual maize stalks from the untreated plots was internally tunnelled by the feeding larvae, while the internal stem tunnelling was low (< 7%) in plants treated with Millettia at concentrations of 3,5 and 10%. Among the treatments with Millettia, higher yields (37–48 decitonnes/hectare) were obtained from maize plots treated with 5% concentration. The use of the aqueous crude seed extract of M. ferruginea at a concentration of 5% applied two to three times is recommended for the control of B. fusca in maize.


DR. J. K. MADDOX said that a completely new era In medicine was being entered. Selye's work was interesting and original. While no doubt many other workers had difficulty in accepting his views just as they were, Selye had given a tremendous stimulus. Many of his experimental results had been borne out, and had led to the testing by Hench and others in the clinical field of the substances under discussion; he had made a great contribution. Dr. Maddox referred to the value of the concise summaries presented by Dr. Harrison and Dr. Day, and said that they had saved the a.udience present at the meeting from the stress ~f reading the enormous literature now surrounding the subject.


Java is a managed programming language, and Java programs are executed in a virtual machine (VM) environment. Java VMs not only execute the primary application program, but also perform several other auxiliary tasks at runtime. Some of these auxiliary tasks, including the program profiling and security checks, are typically performed inline with the program execution, stalling the application progress and slowing program execution. We hypothesize that the execution of individual inline auxiliary tasks do not need knowledge of the entire previous program state. In such cases, it might be possible to abstract individual or sets of auxiliary tasks, along with the code statements that compute the required program state, and execute them in a separate thread. The results of such abstracted auxiliary tasks can then be made available to the main program before they are needed, eliminating the execution time stall and improving runtime program efficiency. However, to test this hypothesis we need access to robust tools to determine and generate the program slice required for each auxiliary task. The goal of this thesis is to study existing Java slicers, test their ability to generate correct executable slices, and evaluate their suitablity for this project. Additionally, we also aim to compare the size of the static slice with the minimal dynamic program slice for each task. This comparison will allow us to determine the quality of the static slicing algorithm for Java programs, and provide us with knowledge to enhance the slicing algorithm, is possible. To our knowledge, one of the most robust static Java slicer implementation available publicly is the Indus Java Analysis Framework developed at Kansas State University. We also found the latest dynamic java slicer, which was developed at Saarland University. For this thesis we study these two state-of-the-art Java slicers and evaluate their suitability for our parallelization project. We found that although the Indus slicer is a very efficient and robust tool for the tasks it was originally intended to per-

With respect to transport and mobilities literatures this paper (1) offers from historical geography, the suggestion that mobilities insights are not restricted to the present or future, (2) illustrates this through a microscale analysis of road maintenance and (3) and, most importantly, focusses on the upkeep of the road network whereas most of the existing work is on the creation and extension of roads as part of state building projects. Road maintenance it is concluded is itself a highly mobile activity and it is also contended that the road itself is a mobile and not a stable platform.


We have performed smoothed particle hydrodynamics simulations to study the response of the central kiloparsec region of a gaseous disk to the imposition of nonaxisymmetric bar potentials. The model galaxies are composed of three axisymmetric components (halo, disk, and bulge) and a nonaxisymmetric bar. These components are assumed to be invariant in time in the frame corotating with the bar. The potential of spherical γ-models of Dehnen is adopted for the bulge component whose density varies as r−γ near the center and r−4 at larger radii and, hence, possesses a central density core for γ = 0 and cusps for γ>0. Since the central mass concentration of the model galaxies increases with the cusp parameter γ, we have examined here the effect of the central mass concentration by varying the cusp parameter γ on the mechanism responsible for the formation of the symmetric two-armed nuclear spirals in barred galaxies. Our simulations show that the symmetric two-armed nuclear spirals are formed by hydrodynamic spiral shocks driven by the gravitational torque of the bar for the models with γ = 0 and 0.5. On the other hand, the symmetric two-armed nuclear spirals in the models with γ = 1 and 1.5 are explained by gas density waves. Thus, we conclude that the mechanism responsible for the formation of symmetric two-armed nuclear spirals in barred galaxies changes from hydrodynamic shocks to gas density waves as the central mass concentration increases from γ = 0 to 1.5.


© 2018 Deputy of Research and Technology of Baqiyatallah Hospital Abstract Introduction: The quality of construction and hotel accommodation in health centers is one of the many factors affecting the physical and mental state of patients. Poor hotel services and low quality structures may exacerbate behavioral disturbances and anxiety, thus, ultimately reduce the pain tolerance of patients. Therefore, the present study was conducted to determine the relationship between patients' pain tolerance and their suffering with different dimensions of hoteling and hospital structures. Materials and Methods: The present study is a descriptive-practical investigation. The sample population was randomly selected from 250 patients who had been referred to Amir-Alam Hospital; Tehran/Iran. Data were collected through a researcher-made questionnaire. A Cronbach's alpha coefficient of about 0.7 was estimated to determine the reliability of our questionnaire. In the end, SPSS version 24 was used for data analysis. Results: The results of simultaneous regression analysis indicated that among the two variables of hospital structures and hoteling; only the hoteling variable was able to influence the pain tolerance of patients by about 21%. Also, among different dimensions of hoteling services, our study found a strong relationship between patients' rights and their pain tolerance. Economic and guidance dimensions were also found to be correlated with pain tolerance to lesser extents, respectively. Conclusion: In order to augment the pain tolerance of hospitalized patients, it is necessary to contemplate on patients' rights in planning of hotel building and the quality of the structure.


The effects of antibiotics plus a sulfa compound added to a suckling pig ration were studied. Twenty-eight three week old animals were used. The 18 males and 10 females, all by the same boar, were divided at random into two experimental groups. The total experimental period was 175 days, divided into periods of 85 days for each litter. The following results were obtained: a) The animals receiving the ration plus antibiotics and sulfa gained an average of 0.240 kg per day; they consumed in addition to the sows milk 0.419 kg of ration daily. The feeding efficiency was 1:1.7 and the total cost per kg of gain was NCr$ 1.11. b) Those animals fed the untreated ration showed an average daily gain of 0.200 kg. In addition to the sows milk they consumed 0.367 kg daily with a feeding efficiency of 1:1.8. The total cost per kg of gain was NCr$ 1.22.

Background. The accuracy of clinical staging is known to be insufficient in stage II endometrial carcinoma. Also the optimal management of this disease is controversial. In this study we evaluate diagnostic accuracy and prognostic factors with special reference to treatment modalities of stage II endometrial carcinoma.


A procedure is presented for constructing calibration curves of X-ray fluorescence activity versus analyte concentration for finite multicomponent media. The composition must be known for all components other than the low-concentration analyte. If these compositions are not known, the system's mass absorption coefficient must be measured. The analyte must be present in low enough concentration so that it does not contribute significantly to the total mass absorption coefficient. The calibration curve for a multicomponent system is constructed numerically from data on analyte activity versus secondary component composition in binary systems (analyte plus one secondary component). Thus calibration curves for any system containing the analyte and n secondary components are constructed from data on the n corresponding binary systems. The method is found to reproduce measured activities of uranium solutions with an accuracy of 5–7%.

Cybersickness refers to a group of uncomfortable symptoms experienced in virtual reality (VR). Among several theories of cybersickness, the subjective vertical mismatch (SVM) theory focuses on an individual's internal model, which is created and updated through past experiences. Although previous studies have attempted to provide experimental evidence for the theory, most approaches are limited to subjective measures or body sway. In this study, we aimed to demonstrate the SVM theory on the basis of the participant's eye movements and investigate whether the subjective level of cybersickness can be predicted using eye-related measures. 26 participants experienced roller coaster VR while wearing a head-mounted display with eye tracking. We designed four experimental conditions by changing the orientation of the VR scene (upright vs. inverted) or the controllability of the participant's body (unrestrained vs. restrained body). The results indicated that participants reported more severe cybersickness when experiencing the upright VR content without controllability. Moreover, distinctive eye movements (e.g. fixation duration and distance between the eye gaze and the object position sequence) were observed according to the experimental conditions. On the basis of these results, we developed a regression model using eye-movement features and found that our model can explain 34.8% of the total variance of cybersickness, indicating a substantial improvement compared to the previous work (4.2%). This study provides empirical data for the SVM theory using both subjective and eye-related measures. In particular, the results suggest that participants' eye movements can serve as a significant index for predicting cybersickness when considering natural gaze behaviors during a VR experience.


The relationship between righteousness and profit is the basic issue in our country's economic ethics. Having a deep theoretical connotation, it needs to be defined from macroscopic, medium and microscopic perspectives.


Even today in the 21st century India, the psychosocial and cultural environments have innumerable prejudiced traditions and redundant customs: dowry, child marriage, illiteracy, physical and mental violence, etc. The Indian girls because of their secondary status in the society may have low self-esteem and poor psychological well-being. Thus it becomes important to study the psychosocial and cultural barriers faced by Indian girls in order to offer a timely correction that can help them play a substantial role in shaping-up the future village society. The broad objective of the present study was to identify the psychosocial and cultural barriers in a village society which hindering to get girls' full potential. Two hundred and ten participants, between the age group of 13-19 years, from District Rohtak in Haryana (India), responded in a specific survey. Interviews and focus group discussions were also held. About 10 discourses were taken with rural women. Results obtained show certain factors as inhibitors (e.g. harmful traditional practices, conflicting situations, gender discrimination etc.). The implication of the findings in providing directions to policy makers, social scientists, and health practitioners towards rural areas regarding adolescent girls has been discussed.


An old and yet new problem is how to evaluate thermally oxidized fats and oils for the sake of their safe use by general public. Recent findings that heat abused fats and oils contain toxic components have stimulated research in this direction. Numerous papers have been published in attempt to provide useful analytical means' 6)• A good review on this subject matter has been given by Waltking et al.6' and a discussion in relation to toxicities of these components and on analytical means reported in the literature has been summarized by one of the authors''. Methods that have been proposed for evaluation of thermally oxidized fats and oils may be devided into two categories ; (1) a combination of conventional methods that have been used for quality control of fresh oils such as IV, AV, carbonyl value (COV), or determination of polymers in conjunction with physical measurements, and (2) various types of chromatography, for example liquid chromatography for the determination of toxic dimers or polar components' '°, gel filtration chromatography° "'" 13', and gas liquid chromatography for the determination of polymers'. On the other hand, TLC received a very little attention' 4',",, Methods that are to be of practical value for evaluation of used frying oils would have the following requirements ; simple in operation, less time-consuming, reproducible results, and possibly a small sample size. Thus, the present study was undertaken to comply as much as possible with these requirements. The method developed here is essentially direct scanning under UV of polar (P) and apolar (Ap) fractions separated by TLC. There are three types of heating condition * Present address : So-Ai Women's Junior College , 27, 4-chome, Honmachi, Higashi-ku, Osaka


Context The notion of the periphery and its relationship to tourism is one that has been a source of debate for many years. The concept of a periphery obviously raises the question of peripheral to what, while the term is often used in a relatively negative context with respect to levels of development and/or influence on central government decision-making. What the term does raise of course is the extent to which location still matters at a time when physical, virtual, capital and human mobility is supposedly greater than ever before. The four contributions therefore highlight a number of key points and debates surround the relative importance or, and relationship between, location and tourist movement. The lead piece by C. Michael Hall, from the Pacific periphery of the South Island of New Zealand, is charged with the topic of does tourism consume place and therefore lead to the loss of the periphery, and perhaps some of the very qualities that attracted tourists to it in the first place. The first response by David Harrison, also from the Pacific, looks at both the geographical and broader sodal scientific understandings of periphery. The second response from David Weaver utilizes the concept of experiential consumption to interrogate Hall's paper and also link to Harrison's reference to the importance of development theory in understanding notions of periphery. The final response from GeoffW all approaches the topic from an overtly geographical perspective and brings the research probe full circle.


The author analyzes President Avila Camacho's politics towards Spain, regarding both Franco's dictatorship and the Republican exile, during the first years of his presidency. This work also analyzes if Avila Camacho continued the politics of Cardenas and how Spain conceived the practical reality of the posrevolutionary regime. Special attention is paid to the negotiations  of the Junta de Auxilio a los Republicanos Espanoles (JARE; Union for the Aid of Spanish Republicans), directed by the socialist Indalecio Prieto, and to the reasons for the Mexican intervention in this institution of aid.


In this paper, Bayesian hierarchical modeling techniques are used to identify and rank hazardous intersections for bicycles in Leuven, a small university town in Belgium. The objective of this paper is to infer the process of listing the most dangerous intersections, based on the available accident data. The hierarchical random effects model allows the specification of different sources of variation, namely the variation between intersections and the variation within each intersection. The Gibbs sampler is used to explore the distribution of the bicycle accident proportions. An important advantage of the Gibbs sampler is the possibility to sample complex functions of the bicycle accident proportions, like the rank of an intersection. It is shown that the ranking itself could be seen as a density. Since the bicycle accident proportions have a stochastic character, the ranking of intersections based on the mean posterior proportion cannot be deterministic. Ranking hazardous sites is an interesting means to get insight in dangerous locations, but there is no such thing as "the" correct ranking. This paper investigates the question whether a ranking alone can give enough evidence for the selection of dangerous sites. TRB 2003 Annual Meeting CD-ROM Paper revised from original submittal. Van den Bossche, Wets and Lesaffre 3 INTRODUCTION In the year 2000, almost 10% of all seriously and fatally injured road accident victims in Belgium were bicyclists. Moreover, 34% of all seriously and fatally injured victims are to be found in urban areas (1). One may conclude that the accident risk for vulnerable road users is too high. It is important to improve their situation, and to rank order the sites that are particularly dangerous for this subgroup. In this paper, Bayesian binomial hierarchical modeling techniques are used to identify and rank hazardous intersections for bicycles in Leuven, a small university town in Belgium. The objective of this paper is to obtain a ranking of the most dangerous intersections, based on the available accident data. The Gibbs sampler is used to explore the distribution of the bicycle accident proportions. An important advantage of the Gibbs sampler is the possibility to infer not only an estimated proportion or count, but also complex functions of the bicycle accident proportions, like the rank of an intersection (2). Since the bicycle accident proportions have a stochastic character, the ranking of intersections based on the posterior mean proportion cannot be deterministic. When decision makers base their investment choices on a ranking of dangerous sites, they should recognize that the ranking is probabilistic in nature. The strength of a particular ranking scheme may be questioned when taking into account the accompanying uncertainty. The choice for a small university city to investigate bicycle accidents at intersections can be easily explained. First, since most of the students at university stay in Leuven on weekdays, it is to be expected that they move around by bike. Because of the higher concentration of bicycles, it would be interesting to know the most dangerous sites. Second, the local government is working on a mobility plan. Authorities want to stimulate the use of bicycles in the inner city. In order to provide a save infrastructure, a selection of dangerous road sections is made, and investments are done according to a priority list (3). Because intersections have always been dangerous locations, it makes sense to look for an intersection prioritization. At first sight, the selection of hazardous intersections seems to be a straightforward task. Hauer and Persaud (4) describe a two-stage procedure to identify hazardous locations, which can be applied to intersections as well. In a first step, accident history of different intersections is reviewed to select a number of apparently dangerous sites. In the second step, the selected intersections are studied in more detail in order to optimally assign investments. However, the intersections with the highest observed bicycle accident rate are not always the most dangerous ones. It is known that the number of accidents at a specific location is fluctuating from year to year. By chance, one year an intersection may have an extremely high count of accidents, without being really hazardous. If investments are to be spread over different locations, decision makers are more interested in sites where accidents are caused by permanent problems. Using empirical accident rates as estimates, without taking into account this uncertainty, one cannot guarantee that the most dangerous sites will be dealt with first. Recently, Bayesian techniques have been used to solve these problems in accident ranking. Although the problem of hazardous intersection identification has been widely discussed in literature (5), the interest in Bayesian methods to improve the process only originated in the eighties. Ever since, many applications used in some way an Empirical Bayes approach. Hauer (6) presented the Empirical Bayes approach as a better estimate of the expected number of accidents, because of the enhanced accuracy of the estimates. Hauer and Persaud (4) examined the performance of some identification procedures. Empirical Bayes methods were used to estimate proportions of correctly and falsely identified deviant road sections. Belanger (7) applied Empirical Bayes methods to estimate the safety of four-legged unsignalized intersections. The results were used to identify black spot locations. Hauer (5) reviewed the development of procedures to identify hazardous locations in general. Vogelesang (8) gives a very comprehensive overview of Empirical Bayes methods in road safety research. The use of hierarchical Bayesian models in traffic safety is less widespread. Schlüter et al. (9) deal with the problem of selecting a subset of accident sites based on a probability assertion that the worst sites are selected first. They propose three criteria for site selection: (a) the posterior probability that the underlying accident rate for a site is larger than the underlying accident rates of the other sites by a given amount, (b) the probability that the number of accidents at a site during the next period will exceed some specified threshold and (c) the expected number of future accidents. To estimate accident frequencies, a hierarchical Bayesian Poisson model has been used. Christiansen et al. (10) developed a hierarchical Bayesian Poisson regression model to estimate and rank accident sites, using a modified posterior accident rate estimate as a selection criterion. Davis and Yang (11) combined hierarchical Bayes methods with an induced exposure model to identify intersections where the crash risk for a subgroup is relatively high. Point and interval estimates of the relative crash risk for older drivers were obtained using the Gibbs sampler. The paper is organized as follows. First, some concepts of hierarchical Bayes, Markov Chain Monte Carlo simulation and Gibbs sampling are briefly described. It is also shown how the rank distribution for each intersection can be sampled. This section is followed by a description of the data set. Next, the results of an empirical study on 168 intersections are presented and discussed. The paper is completed with some conclusions and directions for future research. TRB 2003 Annual Meeting CD-ROM Paper revised from original submittal. Van den Bossche, Wets and Lesaffre 4 BAYESIAN HIERARCHICAL MODELS AND MCMC (GIBBS) SAMPLING The problem of bicycle accident proportions can be expressed in a binomial hierarchical model. A group of 168 intersections in the inner city of Leuven is examined and the number of accidents in the period 1991 to 1998 is counted. In some of the accidents at an intersection, bicyclists might have been involved. The objective is to find, for each intersection, an estimate of the proportion of bicycle accidents. Hierarchical Models Suppose that the true proportion of bicycle accidents at intersections is θ. In this case, it is implicitly assumed that accidents at all intersections happened in similar circumstances. This is not a very realistic setting, and it makes sense to assume that accidents at different intersections occur in slightly different conditions. Indeed, it is natural to suppose that the intersections and their accidents are not completely similar. Accidents may occur at different times, with different drivers. Intersections are to be found at different locations, with a specific infrastructure. It is to be expected that the proportions for the intersections will differ, but it might be acceptable to assume that they are drawn from the same distribution. Instead of using θ as the proportion of bicycle accidents, a proportion θi is used for intersection i. All θi values are sampled from one population, called a hyper population. Based on Gelman et al. (12), this setting can be schematically represented as in Figure 1. Here, the value ri (i = 1, 2, ..., p) is the observed number of bicycle accidents at intersection i. The estimated proportion of bicycle accidents at intersection i is equal to ri / ni. This is an estimate for the "true" (but unobserved) proportion θi at intersection i.  Once the hierarchical structure is determined, a prior distribution should be chosen for the hyper population and its parameters. When there is no information available for the hyper parameters, a noninformative prior is preferred. One frequently used approach is to obtain point estimates for the parameters of the hyper prior from the data. This is the Empirical Bayes approach. Since the hyper parameters are replaced by their point estimates, this model cannot fully take into account their uncertainty. In a full Bayesian approach, a prior distribution is specified for the hyper parameters, to express the uncertainty about their true value. If no further prior information is available, a non-informative prior


OBJECTIVE
This study examined the effects of videogame distraction and a virtual reality (VR) type head-mounted display helmet for children undergoing cold pressor pain.

METHODS
Fifty children between the ages of 6 and 10 years underwent a baseline cold pressor trial followed by two cold pressor trials in which interactive videogame distraction was delivered via a VR helmet or without a VR helmet in counterbalanced order.

RESULTS
As expected, children demonstrated significant improvements in pain threshold and pain tolerance during both distraction conditions. However, the two distraction conditions did not differ in effectiveness.

CONCLUSIONS
Using the VR helmet did not result in improved pain tolerance over and above the effects of interactive videogame distraction without VR technology. Clinical implications and possible developmental differences in elementary school-aged children's ability to use VR technology are discussed.


Mobile devices have shown to be useful tools in supporting various procedures and therapy approaches for different purposes. However, when applied to children, particular care has to be taken, considering both their abilities and their acceptance towards the used approaches. In this paper we present mobile applications, designed specifically for children and young patients, aiming at supporting fear therapy procedures. The software was developed following a user centered design approach and offers users an intuitive and metaphor based interaction paradigm that overcomes the paper-based counterpart's limitations. We describe the design process, the software and the results that we have obtained during an exploratory trial study.


ABSTRACT This forum piece discusses the relevance of insights from the field of developmental education in terms of the disruption of face-to-face learning and the important implications on the notions of college readiness for those whose educational experiences have been altered unexpectedly. The concept of college readiness, now more than ever, should be reconceptualized as student readiness. We provide four insights from the well-established field of developmental education to help guide institutions in their responses to these unprecedented life circumstances for students.


Friction Stir Welding being a solid-state process is free from defects generally occurs in fusion welding process. FSW of aluminium alloy has been done on universal milling machine. The high cost and non-availability of friction stir welding machine motivated this research to design and make a new fixture. Many forces appear during the friction stir welding process. They are torque, transverse, axial and lateral forces. Due to presence of these forces the main challenge is to withstand all these forces and this is one aim to fabricate the fixture. For FSW process there is design, development and tested the new economical fixture for universal milling machine. Keyword head: Friction stir welding, fixture, clamps, drilling, milling.

In recent years a number of authors [1], [2], [3], [4], [7], [8], [9] have dealt from various points of view with the question of whether a fundamental unit sq in the quadratic field Q (j/g) is a quadratic residue of a prime p of which g is a quadratic residue. In this paper we will address ourselves to the following problem: Given that g and £0, where g is a prime, are quadratic residues of a prime jt>, find the conditions for sq to be a quartic residue of p. Furthermore, if these conditions are satisfied determine, if possible, whether it is an octic residue of p. The answers to these questions are in terms of the representation of p by binary quadratic forms and have applications to tests for primality and to the divisibility by p of certain terms of the corresponding Lucas' series. These will be discussed in sections 3 and 4. § 1. Besults and conjeetures We begin with q = 2 and p = 8n + l, so that ε2 = ί + J/2 is a rational integer modulo p. Every such prime p is uniquely represented by (1) p = a + 16fc = c + 8d (a Ξ c s l (mod 4)). It was shown in [1] that


The U.S. Naval Air Station in Pensacola participated in the Lipton Regattas for several years. Eight years after this invitation was written, World War II would end with the signing of the Japanese surrender on board Admiral "Bull" Halsey's flagship, the Missouri.


The sidewalk of Au-catalysed GaAs nanowires are studied systematically by using transmission electron microscopy. The cross-sectional shape of the VLS grown nanowires was found to consist of 3 curved surfaces along {112}A. The curved surfaces evolve into three {112}A and three {112}B facets towards the base of the nanowire due to the radial growth around the nanowire. These sidewalls transform to {110} facets at high temperature annealing and the transformation rate is determined by the cross-sectional shape and size of the nanowires.


Significance Faithful and efficient genome duplication is essential for the propagation of life. Aberrant DNA replication can lead to genomic instability and cancer. In eukaryotes, the replication machinery is composed of the DNA-unwinding enzyme Cdc45–MCM–GINS (CMG) and dedicated DNA synthesis factors. Three different polymerases act sequentially on the leading-strand template to establish DNA replication. We describe the architecture and dynamics of the main leading-strand polymerase bound to the CMG helicase, and we propose a mechanism for the establishment of efficient leading-strand synthesis. Our findings provide important insights into how the eukaryotic replication machinery functions to ensure that genome integrity is maintained during replication. The replisome unwinds and synthesizes DNA for genome duplication. In eukaryotes, the Cdc45–MCM–GINS (CMG) helicase and the leading-strand polymerase, Pol epsilon, form a stable assembly. The mechanism for coupling DNA unwinding with synthesis is starting to be elucidated, however the architecture and dynamics of the replication fork remain only partially understood, preventing a molecular understanding of chromosome replication. To address this issue, we conducted a systematic single-particle EM study on multiple permutations of the reconstituted CMG–Pol epsilon assembly. Pol epsilon contains two flexibly tethered lobes. The noncatalytic lobe is anchored to the motor of the helicase, whereas the polymerization domain extends toward the side of the helicase. We observe two alternate configurations of the DNA synthesis domain in the CMG-bound Pol epsilon. We propose that this conformational switch might control DNA template engagement and release, modulating replisome progression.


A trade-off analysis between maneuver period, execution errors, and orbit determination uncertainties is carried out for the Ocean Topography Experiment spacecraft for a given nodal equatorial constraint. Semimajor axis and eccentricity are controlled with minimum impulse using the linear theory of optimal transfer between close coplanar near-circular orbits. Ellipses of equal minimum and average maneuver periods are presented in the (3 execution error, 3 orbit determination uncertainty) space for different nodal equatorial constraints enabling the determination of the appropriate combination of execution errors and orbit determination uncertainties that guarantees a mission required minimum maneuver period for a given nodal deadband.


It is well known that sudden changes in the solution produced by shock waves and contact discontinuities often appear in compressible flow problems. These features of the flow field require very small size finite elements to achieve an accurate solution. However, homogeneous refinement of the whole mesh quickly becomes prohibitive for three dimensional meshes due to computational cost issues. In these situations, the use of adaptive mesh refinement strategies shows advantageous. An h-adaptive unstructured mesh refinement strategy to solve both steady and unsteady compressible flow problems by the finite element method is used in this work. The adaption algorithm is briefly introduced. The main features of the adapted meshes are the presence of hanging nodes and the controlled geometrical quality of its elements. Refinement constraints are enforced to guarantee a smooth size distribution amongst neighbour elements and a posteriori error indicators based on the gradient of the flow variables are used to track discontinuities through the flow field. The algorithm is implemented in the C++ programming language together with the STL and Boost libraries. The mesh adaption code is coupled to an SUPGFEM flow solver which is run in parallel on a cluster of workstations. The spherical blast wave problem known as the Taylor-Sedov problem is solved with this code and the flow field is compared to that provided by the theory.


In present study the thermal properties of the fenugreek powder have been determined and discussed here. The thermal properties of the fenugreek powder are important parameter in designing and fabricating equipment for its processing, developing structures for handling, transporting, processing at different temperature and storage, and also for assessing quality. The study was conducted to investigate thermal properties of fenugreek seed powder at varying moisture content. Thermal conductivity was measured by thermal conductivity meter, specific heat by Differential Scanning Calorimeter whereas bulk thermal diffusivity was determined by using standard relationship. It was found that as moisture content and temperature of fenugreek powder increases, the thermal conductivity and specific heat are increasing, but bulk thermal diffusivity was found to be decreasing in nature.


Artificial neural networks are a set of tools that are widely used for the information classification. Its expansion within artificial intelligence has been due to its use in the Machine Learning area. A fundamental part of the artificial neural networks algorithm is the so-called activation function, the above because it is the part that triggers the process as a whole and due to its result the neuron/perceptron sends its outputs. Back-propagation activation function of an artificial neural network is also described; this is artificial neural network with a simpler functioning whose adaptation has made it especially attractive to pattern recognition; also, a different algorithm such as Swish is introduced. As part of the pattern recognition study, three wind classifications present on the Mexican Republic Atlantic coast are formed, each group is made up of graphic files referring to meteorological maps with wind indicators in order to feed the network and as new maps are generated, the Artificial Neural Network will be an aid in the meteorological patterns detection.


Introduction: The introduction of Multi-Detector Computed Tomography (MDCT) has revolutionised clinical practice. Mediastinal lesions represent challenging problems faced by the radiologist and often a chest radiograph is inadequate for answering the queries of clinicians. MDCT is employed to diagnose various causes of mediastinal widening and often correct diagnosis is obtained using CT alone, thus obviating invasive diagnostic procedures. Aim: To assess the diagnostic accuracy of MDCT in mediastinal mass lesions compared to histopathology. Materials and Methods: A prospective observational study comprised of 52 patients who underwent MDCT examination for evaluation of mediastinal masses. All these patients subsequently underwent histopathological examination either by CT-guided biopsy, transthoracic needle aspiration, endoscopic biopsy or by surgical resection. Sensitivity, specificity and accuracy of each type of lesion was calculated and tabulated. Results: The study population comprised of 52 patients out of whom 43 cases (83%) were predicted correctly by CT when compared with histopathology diagnosis. The sensitivity of detecting malignancy was 100% and specificity was 92.6%. The present study had accuracy of 96.2% in differentiating malignant mediastinal masses from benign lesions. Conclusion: MDCT is useful in evaluating the distribution of mediastinal masses and their relationship to adjacent structures and differentiating between malignant mediastinal masses from benign lesions.


This article deals with one of the most interesting contemporary conflicts between fundamental rights, that concerning freedom of thought, conscience and religion, with particular reference to the use of the Islamic headscarf in educational institutions (I, The conflict). As an illustration of this conflict, we shall focus on one particular case, Leyla Sahin's case, brought before the European Court of Human Rights in 2004 (II, The case). That case will be our starting point, as it contains some of the essential coordinates which must be borne in mind when resolving such conflicts. Our next step will be to identify these coordinates (III, The coordinates). Then with these coordinates we shall examine the course set by the different rulings that have been handed down in order to resolve the conflict and by the specific legislation enacted (IV, The course). Finally, we shall attempt to draw certain conclusions (V, Conclusion).


The individual characteristics of mesons and protons in a shower are obtained as functions of the energy of the incident relativistic nuclei in interactions of relativistic nuclei with nuclei at a high degree of overlap of the geometric cross sections. Agreement is observed with calculation by the model of the collective mechanism of interaction of nucleus--nucleus pionization.

A recrudescence of the Zoonotic Cutaneous Leishmaniasis has been recorded in Algeria and constituted a serious problem of public health. The disease prevails in Algeria in an endemo-epidemic mode. In this context, the area of Ain Skhouna situated near to the Chott chergui has recorded several human cases. Filed into the middle of the steppe with a semi-arid climate, this area was chosen to conduct a bio-ecological study on rodent reservoirs from July 2010 to August 2013. Biotope analysis and active burrows counting were realized on nine sites in order to cover the pullulated rodent areas. The catching was realized through each site. Rodents were manually caught after flooding by water cisterns and breaking their burrows. This type of trap was preferred over the rest of traps used because it can trap other small animals. This allows the capture of live animals which offers a very good exploitation. The preparation of faunistic material was carried out by inhalation of volatile anesthesia. Identification, biometric measurements, necropsy of rodents and histological sections of lymph nodes which drain ears lesions were done at the laboratory. Results showed an average of 2 to 3 active burrows per m. They also showed a varied population of rodents, 84% of Psammomys obesus and 16% of Meriones shawi. The medullary macrophages of lymph nodes revealed numerous amastigotes inside their cytoplasm seen as small intracellular rounded bodies. Later, we introduced captured weasels which we have identified as Mustela nivalis inside a closely monitored zones and investigated their predator effect on rodents and the ecosystem of Ain Skhouna. After a daily monitor of four week, we noticed a gradual decrease until total absence of rodents. Visits on site showed inactive burrows until 2013. Therefore this voracious behavior is an efficient measure of controlling these agricultural devastating reservoirs by its simplicity and ecological impact on the environment.


On the basis of a comparison between the criteria for assessment of professional titles applied to the liˉbrarians and that applied to the teachers,this article puts forward some scientific,rational and serviceable proposals.


There are many limitations in dealing with rapidly changing traffic demand in urban cities. Thus recently, traffic operation and management skills are more emphasized rather than the expansion of traffic facilities. In particular, in the interrupted flow formed by signalized intersections, it is quite important to give optimal signal timing to each intersection with consideration of progression. However, as fixed signal times per direction can affect passing capacity in signalized intersections, the present four-signal phase including a left-turn signal has many limitations, including reduction of directional road capacity when traffic demand is increases dramatically during peak hours. Because of this problem, lots of studies about internal metering techniques for oversaturated signal control skills have progressed but these techniques are not used widely due to the absence of detectors for queue sensing in real-time signal control systems. In this research, a new methodology called the "restrictive left-turn signal control", which is already used at the intersection above Samsung subway station, is suggested in order to reduce control delay of urban arterial roads. The restrictive left-turn signal control allows a driver to make a U-turn and then a right turn instead of turning left in that intersection. With this change, the restrictive left-turn signal control can contribute to increased intersection capacity by reducing the number of signal phases and maximizing the through phase time. However, road structure and traffic conditions at the target intersections should be considered before the adoption of the proposed signal control.


The Ac-Me Specific Gravity Gas Balance is examined as an accurate and portable instrument for testing the specific gravity of gas. Another instrument, the Ac-Me Junior, is approximately one-quarter as large as the Ac-Me; consequently, it is well adapted for field use when transportation of the balance to the location of the gas to be tested is difficult, or for laboratory use when use of a minimum gas sample is desired. Methods of reading the balances are discussed, and sample test readings including specific gravity calculations, are given.


Objective To study the clinical application of high-intensity focused ultrasound(HIFU) in the treatment of ectopic pregnancy.Methods Thirty patients with ectopic pregnancy were treated using HIFU,among which 21 belonged to unruptured tumor type and 9 belonged to ruptured type.The value of β-HCG and the variation of focus sonography were compared before and after treatment simultaneously.The condition of the patients and the syndrome were recorded during the treatment.Results The value of β-HCG in 25 patients were declined to the normal level in one month.Five patients were failed in HIFU treatment. The volume of the focus became smaller obviously,focal echaes were enhanced,and the blood stream in the focus was decreased after treatment,and no syndrome occured obviously.The level of the β-HCG and the volume of the focus after the treatment were significant different as compared with before(P0.05,P0.01).Conclusion HIFU is one of the effective treatments of ectopic pregnancy.


Silicon Carbide devices can achieve very high switching speed, but that requires specific packaging solutions. In this paper, we discuss the effects of parasitic devices on the switching behaviour. Three different prototypes are then presented, offering three different packaging and integration approaches (low inductance packaging, integration of the gate drivers, integration of common-mode filtering). The consequences on the switching speed are discussed.


Interference aware user scheduling in fixed grid-of-beam (GoB) transmission is envisaged to significantly benefit from the receiver initiated busy burst (BB) protocol. Fixed GoB scheduling relies on the knowledge of the location of the intended users as well as the vulnerable users which effectively is provided by the BB protocol via exploitation of channel reciprocity. This paper studies the hybrid BB and GoB (BB+GoB) approach in a Manhattan environment. The new proposed hybrid interference avoidance scheme with an underlying score based scheduler is evaluated by means of system level simulations, and is compared against a pure GoB approach with the same scheduler as well as the BB based interference avoidance techniques applied to omnidirectional antennas. The results show an improvement in both system throughput and fairness (defined as cell edge user throughput). In particular, system throughput of up to 238.5 Mbps/cell or user throughput of up to 8.88 Mbps/user for the lower 10%-ile of users are shown to be feasible. In particular, the hybrid BB+GoB scheme exhibits a 16-fold improvement at the lower 10%-ile compared to pure GoB technique.

A retrieval technique for some hydrocarbon compounds (ethylene, ethanol, methanol, and isopropanol) concentration from opto-acoustic measurements of total absorption at several fixed wavelengths of the CO2-laser is presented in the report. In the gases concentration reconstructing, the method of least squares (LSM) as well as linear programming (LPM) and regularization (RM) methods were used. The problem of accuracy of the gases concentration retrieval depending on the quantity of simultaneously analyzed hydrocarbon compounds is discussed. Monitoring of gas composition of the atmospheric air by the optical absorption methods calls for instruments which are highly sensitive to absorption, highly selective, and capable of determining the concentration of trace gases in multicomponent mixtures. One of such instruments an opto-acoustic (OA) gas analyzer with a resonance cell. To analyze the content of gases under study, the atmospheric air, preliminary purified from atmospheric aerosol is pumped through the OA cell. Our work is aimed at studying of the accuracy of gas concentration reconstruction from OA measurements depending on: (1) error in determining the absorption coefficients Kij; (2) available model of continuous absorption ac(vi); (3) random error in measuring signals.

ABSTRACT By employing a theoretical model of Comprehensive Assistive Technology (CAT), this study aims to examine the impact of Information and Communication Technology-based assistive technology (ICT-based AT) on both the working and social activities of visually impaired people (VIP) in non-Western societies of China, with an emphasis on benefits, risks, problems, and comparisons to visually-abled people, utilizing participant observation and in-depth interviews with 16 VIP who work in blind massage shops. We maintain that ICT-based AT, as the eyes of VIP, benefits these individuals greatly in humanistic and social areas such as empowerment and social inclusion, but also causes new communication problems. The study contributes theoretically to this field by enriching the literature concerning the activity attributes of the CAT model, and critically reflecting on technology overuse and media overconsumption among VIP.


Using a sample of 493 adults, the present investigation examined the psychometric properties of a Brazilian adaptation of the Expressions of Spirituality InventoryRevised (ESI-R; MacDonald 2000a), a measure of an empirically derived five dimensional model of spirituality which has been shown to have some promise for cross-cultural research. Reliability analysis indicated that the ESI-R dimensions produced satisfactory inter-item consistency coefficients. Exploratory factor analysis provided evidence generally supportive of the replicability of the five dimensions. Confirmatory factor analysis testing two competing factor models (four versus five factor) provided some support for both models. However, the five factor model emerged superior. Support for both convergent and discriminant validity of the ESI-R dimensions was also obtained. Overall, the findings of this study are consistent with those seen with samples from other cultures and suggest that the ESI-R holds promise for use in spirituality research in Brazil.


The use of sunscreen for the purpose of effectively absorbing sunlight in order to prevent the occurrence of premature aging and skin cancer. Nanoemulsion is very effective to be applied as cosmetic preparation due to their characteristic properties of small droplet size with high surface area enables effective delivery of the active ingredients. It is transparent appearance and thermodynamically stable. The formulation of the nanoemulsions was prepared in various ratios of Tween 80 as a surfactant and ethanol as co-surfactant using avobenzone and octyl methoxycinnamate as sunscreen agent.The nanoemulsion was evaluated for particle size, centrifugation, stability during experiment for 12 weeks of storage at room temperature, pH, viscosity, and SPF value. Nanoemulsion in the ratio of tween 80 and ethanol (34:26) had the smallest average particle size of 163.31 nm with yellowish color, clear and transparent appearance, pH value (7.46 ± 0.00), viscosity value (75cP ± 25), did not show any separation or creaming in the centrifugation, stable during experiment for 12 weeks of storage at room temperature. The sunscreen nanoemulsion preparations containing avobenzone and octyl methoxycinamate with the ratio of Tween 80 and ethanol 34:26 contributed to give SPF value of 16.80 ± 0.08. This formulation could be considered efficient for sunscreen cosmetic use

Methods and devices provide a user interface that provides visual cues when a document pan or scroll has reached an end or boundary by distorting the document image in response to further user inputs. The image distortion functionality may include shrinking, stretching, accordion expansion, or bouncing of a document image. The degree of image distortion may be proportional to the distance that a user input would have the document move beyond the encountered boundary. When a boundary of a document image is reached during a rapid pan or scroll, a bouncing image distortion may be applied to the document image to inform the user that the document reached a boundary during the movement.


This paper investigates the classification of odours using an electronic nose mounted on a mobile robot. The samples are collected as the robot explores the environment. Under such conditions, the sensor response differs from typical three phase sampling processes. In this paper, we focus particularly on the classification problem and how it is influenced by the movement of the robot. To cope with these influences, an algorithm consisting of an ensemble of classifiers is presented. Experimental results show that this algorithm increases classification performance compared to other traditional classification methods.


Purpose: The purpose of this study was to compare the ultimate failure load, stiffness and elongation of 3 different MPFL patellar fixation techniques: suture anchor, sutured tendon (a semi-tunnel technique, the free ends were sutured) and folio tendon (a semi-tunnel technique, the folio ends were passed through by suture). Materials and methods: We used six fresh-frozen cadaveric knees, each of them was performed MPFL reconstruction by the three techniques orderly. We named them suture anchor group, sutured tendon group and folio tendon group. Suture anchor reconstruction was completed with 2 parallel 3.0-mm biocomposite suture anchors. Sutured tendon group: The free ends of the sutured tendon were pulled into patellar semi-tunnels. Folio tendon group: The two folded ends were pulled separately into the patellar semi-tunnels. After preconditioned each graft, we recorded maximum load, stiffness, and elongation. Results: The suture anchor group had lower mean failure load (222.17±5.19 N) than the sutured tendon (364.50±2.42 N) and folio tendon (367.83±5.00 N) group. Compared with the folio tendon (43.73±2.62 N/mm) group, the sutured tendon group (28.68±6.92 N/mm) had lower stiffness values. There was no significant difference in the ultimate load between the sutured tendon group (364.5±2.42 N) and the folio tendon group (367.83±5.00 N). But the most important finding was that the sutured tendon group's elongation was longer than the folio tendon group in the initial phase of the test. Conclusions: The suture anchor group was found to be weaker than the sutured tendon and folio tendon group when compared the ultimate failure load. The overlength of the sutured tendon group in the initial phase of the test verified that the tendon slide relatively to the suture. Clinical relevance: This study compared the biomechanical properties of 3 methods for patellar graft fixation in MPFL reconstruction surgery. It supported the use of sutured tendon group would occurs the tendon slide relatively to the suture. The folio tendon method provided the strongest strength and could avoid tendon slide relatively to suture.


In this paper, we consider the problem of achieving monotonic tracking control for any initial condition (also referred to as global monotonic tracking control). The main result of this paper is to show that in the strictly proper case, the solvability conditions can be greatly simplified with respect to the non-strictly proper case, and take a form that appears more insightful from a system-theoretic perspective.


Saturated fatty acids (FA) in the carcass of ruminants represent a critical topic in human alimentation given by their relationship with cardiovascular diseases. In view of this, Saccharomyces cerevisiae (Sc) represents an alternative to modify the meat FA pro le by increasing the ratio of deposited unsaturated FA, because of its high levels of unsaturated fatty acids. An experiment was carried out using 30 commercial growing lambs (20 ± 0.9 kg LW), distributed into three groups with 10 animals each, which was placed into one of three evaluated treatments: 0, 3, and 5 g Sc animal−1 d−1, in order to determine the productive performance of the animals, plasmatic cholesterol levels, and FA deposited in the carcass. A totally random design was used. Data were analyzed using the PROC GLM, considering ten repetitions per treatment. Mean comparison of the treatments was done through the Tukey test. The results show that adding 3 g animal−1 d−1 Sc partially decreased (p < 0.05) DM intake and food conversion in the evaluated periods without a ecting (P > 0.05) daily weight gain. It also did not a ect (p > 0.05) muscle area of the Longissimus dorsi, fat thickness and total cholesterol in the blood. As the Sc dose increased, the levels of myristic, palmitic, oleic, and linoleic acids decreased (p < 0.05). Sc doesnt a ect the animal performance, neither improvement the carcass unsaturated FA pro le, however, saturated FA concentrations decreases.

This paper is a summary of ideas and methods related to protection of people from the negative impact of electronic technology. While conducting research, the author intended to clearly define the prevailing negative impact of torsion fields in comparison with electromagnetic radiation. Electromagnetic fields warm the tissues of a person using all sorts of gadgets, while torsion fields provide influence at the gene level. Much attention is paid to the technology of protection from torsion fields. For a more complete understanding of the problem of protecting the population from the negative influence of torsion fields, the authors considered the concept of the "fabric of the universe" developed by several authors, which enabled representing the processes occurring in Physical Vacuum in a more distinct way. The fact that virtual particles have their own subconscious nature, which differs from ours that was predicted by N. Tesla, has been confirmed.


A calculation model of readout signal from super-resolution near-field structure disk (Super-RENS) is presented. The readout signal on the exit pupil of the objective lens is calculated using finite-difference time-domain method (FDTD) together with a vector model of Gaussian beam and the diffraction method. Calculation results show that Super-RENS disk has a high spatial resolution beyond diffraction limit, and properties of readout signal are quite different from that of conventional optical disk.

Samples of the geothermal fluids in the Miravalles, Costa Rica, geothermal system were collected from production wellbores using downhole fluid samplers, from flowing wellheads using miniseparators, and from hot springs that discharge in the area. The reservoir fluid at Miravalles is a neutral-chloride-type water, but fumaroles and acid-sulfate springs are present within the main thermal area, and there are bicarbonate-rich hot springs that are clearly related to the neutral-chloride reservoir fluids. Dissolved gases are primarily a mixture of CO{sub 2} with air, but samples collected in the fumarolic areas also contain H{sub 2}S. Water-stable isotope analyses suggest local meteoric recharge, and the reservoir fluid shows oxygen isotopic shifts of about 2.5% due to high-temperature oxygen exchange between water and rock. Chemical geothermometer temperatures are consistent with the measured downhole temperature of 220{degrees} to 255{degrees}C. This pattern of neutral-chloride reservoir fluids with acid-sulfate springs near the source region and bicarbonate-rich chloride hot springs at the periphery of the system suggests a lateral outflow type of hydrothermal system. In addition to the geochemical evidence, temperature profiles from several of the wells show temperature reversals that are characteristic of lateral outflow plumes. We find no evidence for the underlying, higher temperature (300{degrees}C) system,more » which has been suggested by other investigators. 24 refs., 14 figs., 6 tabs.« less


Classical k-ratio models, e.g. ZAF and phi(rho z), used in electron probe microanalysis (EPMA) assume a homogeneous or multi-layered material structure, which essentially limits the spatial resolution of EPMA to the size of the interaction volume where characteristic x-rays are produced. We present a new model for characteristic x-ray emission that avoids assumptions on the material structure to not restrict the resolution of EPMA a-priori. Our model bases on the spherical harmonic (PN) approximation of the Boltzmann equation for electron transport in continuous slowing down approximation. PN models have a simple structure, are hierarchical in accuracy and well-suited for efficient adjoint-based gradient computation, which makes our model a promising alternative to classical models in terms of improving the resolution of EPMA in the future. We present results of various test cases including a comparison of the PN model to a minimum entropy moment model as well as Monte-Carlo (MC) trajectory sampling, a comparison of PN-based k-ratios to k-ratios obtained with MC, a comparison with experimental data of electron backscattering yields as well as a comparison of PN and Monte-Carlo based on characteristic X-ray generation in a three-dimensional material probe with fine structures.


Students, teachers, counselors, and parents are all important in determining the degree to which homework is effective in meeting its goals. Teachers assign homework, parents provide the environment in which it is done, and students—each with a unique profile of motivation and preference for learning—do the homework. It is a challenge for everyone involved to cooperate, share information about children's homework motivation and preferences, and develop strategies to be used at school and at home to attain a better match between what the child likes to do and has to do when learning. This article—prepared to assist teachers, parents, and counselors to meet this challenge—describes a conceptual homework model and a technique of assessing homework motivation and preferences based on the model. Intervention strategies for how to use this knowledge to make students' homework performance more effective and enjoyable are suggested.


Temperature-sensitive thick-film systems based on spinel-type NiMn2O4-CuMn2O4-MnCo2O4 manganites with p-and p+-types of electrical conductivity were obtained. All elements are shown good electrophysical characteristics before and after long-term ageing test at 170°C. It is shown that in two-layer p-p+ systems are typical increases of electrical resistance during ageing test, while three-layer type p-p+-p structures are high stabile.


The resolution of an array is determined by the number and spatial distance of apertures (channels) within the array and the geometry of each aperture. The accurate design of acoustic sensing arrays relies on an a prioiri estimate of the expected far field radiation pattern of reciprocally behaved elements chosen for each aperture which is difficult to calculate under damped and loaded conditions. The estimated response of one channel of a vertical line array, when modeled as a series of rectangular vibrating pistons on a rigid baffle, is compared to the measured response of one channel of a line array comprised of a series of thin rectangular bars under load and operating off resonance. Although simple modeling can predict the 3dB main lobe width of the channel with some accuracy, loading and damping effects will alter the individual element response and hence the sensitivity of the array and side lobe magnitudes when off axis steering. This is important to note when estimating array gain and noise contributions from sidelobes under steered conditions.


The comprehensive investigation of relaxation effect remains difficult. For the first time, a characterization scheme is proposed and demonstrated to identify the relaxation and RTN in filamentary analog RRAM devices. This new method can help deeply understand the physical mechanism of relaxation, and pave the way for developing analog RRAM devices with excellent stability. The identification of the relaxation and RTN also helps design diversified RRAM based deep neural networks with reasonable computing accuracy.

This paper reports on the development of the Rigid-Body-Spring Network (RBSN) approach, which can be categorized as a lattice model, and its application to analyzing quasi-brittle failure of cement-based composites. Attention is first given to elastic stress analysis, which is fundamental to modeling crack initiation and propagation. The potential for modeling crack propagation across random networks is demonstrated through comparisons with theory and mode I fracture test results. Due to the implementation of a crack band model within the RBSN, crack propagation is objective with respect to network component size and geometry. The latter part of the paper presents preliminary efforts toward modeling compressive failure under uniaxial loading, as well as work towards extending the analysis framework to three dimensions.
