TriMeDeC tool for preparing visual teaching materials based on triangular networks

Triangular meshes are frequently used to present different natural phenomena and free‐form shapes. They are generated by different mathematical, simulation, and design tools. Usually they contain a huge number of triangles, which represents a serious obstacle for storing, manipulation, and transmission via internet. However, triangular meshes can be simplified (decimated) yet still preserving the main features of the original mesh. In this paper, TriMeDeC tool for decimation, undecimation, and compression of triangular meshes is presented. The tool helps teachers and students to visualize triangular meshes and simplify them in an interactive way. Its salient feature is an effective data compression algorithm, which produces 2 to 3.5 times smaller output files than the popular WinZIP algorithm. TriMeDeC is very simple to use and can be easily employed by teachers and students. © 2002 Wiley Periodicals, Inc.

An Assessment of Progress in the Use of Alternatives in Toxicity Testing since the Publication of the Report of the Second FRAME Toxicity Committee (1991)

The first FRAME Toxicity Committee was formed in October 1979, with the following remit: a) to conduct a thorough review of current toxicity testing procedures, to assess their reliability and suitability, and to make recommendations for their modification; b) to assess the prospects for developing in vitro, target organ and theoretical model systems which would lead to a reduction in studies on live animals; and c) to act as an advisory group to a FRAME Research Fund for the support of projects aimed at the development and validation of alternative methods for use in toxicity testing. There were 12 founder members, and this group was later augmented by 13 further scientists (1, see also Table 1). At the first meeting of the committee, working parties were established to discuss irritancy, teratology and neurotoxicity testing, and additional working groups were subsequently added to cover other major areas of toxicity testing. The committee met 27 times between October 1979 and November 1982. The report of the first committee was produced in 1982 (2), and this was discussed at a subsequent public meeting, held at the Royal Society, London, the proceedings of which were published in 1983 (3).
A controllable reactor of transformer type

This paper clarifies the operating principles of a controllable reactor of transformer type (CRT). In nature, a CRT is equivalent to a multi-winding transformer for which the low-voltage windings (control windings) operate at short-circuited states in turn. This kind of reactor possesses such advantages as smooth power regulation, low current harmonic content, and fast response. Taking account of the coupling of the control windings, this paper examined the current harmonic content for the work winding by Fourier series decomposition, and thus derived the current harmonic coefficients. Based on the solution of the branch current equation of a multi-winding transformer, and introduction of the concept of equivalent winding impedance, a polygon-type equivalent circuit is proposed for a multi-winding transformer. Subsequently, formulae for the branch impedances of the equivalent circuit are presented. According to the harmonic content constraints, the number of control steps is determined. Then, by combining the MMF and branch current equations, an expanded equation about the winding currents and current-limiting reactances is obtained. According to the feature that the control windings are short-circuited in turn, the current-limiting reactances are calculated for each control winding step by step. At last, based on the proposed equivalent circuit for a multi-winding transformer, a simulation model for a CRT is fabricated with MATLAB/SIMULINK/PSB. The simulation results confirmed the presented work, which underpins the further analysis and design of a CRT.
Image Captioning with Sentiment Terms via Weakly-Supervised Sentiment Dataset

Image captioning task has become a highly competitive research area with successful application of convolutional and recurrent neural networks, especially with the advent of long short-term memory (LSTM) architecture. However, its primary focus has been a factual description of the images, including the objects, movements, and their relations. While such focus has demonstrated competence, describing the images along with non-factual elements, namely sentiments of the images expressed via adjectives, has mostly been neglected. We attempt to address this issue by ﬁne-tuning an additional convolutional neural network solely devoted to sentiments, where dataset on sentiment is built from a data-driven, multi-label approach. Our experimental results show that our method can generate image captions with sentiment terms that are more compatible with the images than solely relying on features devoted to object classiﬁcation, while capable of preserving the semantics.
Heat distribution control using current amplitude and phase angle in zone-control induction heating systems

This paper proposes a new control method to expand the controllable zone number in a zone-control induction heating (ZCIH) system. The ZCIH system consists of multiple working coils and multiple inverters to control the amplitude and phase angle of each coil current to obtain uniformity in the temperature profile across a workpiece. The ZCIH system makes it possible to control the heat distribution, resulting in a fast heating capability at high temperature conditions. This paper derives a relation between the coil currents and the heat generated on each zone, when the phase angle between coil currents are controlled. Based on the analysis, a new control method is proposed to control the generated heat across the workpiece by adjusting both amplitudes and phase angles of the coil currents. Experimental results clarified that the proposed method can control the heat generated on five zones using only three working coils. As a result, N working coils are possible to control the heat generated on 2N-1 zones, leading to a remarkable heat distribution improvement and/or a significant cost reduction in the ZCIH system.
The SRm160/300 splicing coactivator subunits.

The SRm160/300 splicing coactivator, which consists of the serine/arginine (SR)-related nuclear matrix protein of 160 kDa and a 300-kDa nuclear matrix antigen, functions in splicing by promoting critical interactions between splicing factors bound to pre-mRNA, including snRNPs and SR family proteins. In this article we report the isolation of a cDNA encoding the 300-kDa antigen and investigate the activity of it and SRm160 in splicing. Like SRm160, the 300-kDa antigen contains domains rich in alternating S and R residues but lacks an RNA recognition motif; the protein is accordingly named "SRm300. " SRm300 also contains a novel and highly conserved N-terminal domain, several unique repeated motifs rich in S, R, and proline residues, and two very long polyserine tracts. Surprisingly, specific depletion of SRm300 does not prevent the splicing of pre-mRNAs shown previously to require SRm160/300. Addition of recombinant SRm160 alone to SRm160/300-depleted reactions specifically activates splicing. The results indicate that SRm160 may be the more critical component of the SRm160/300 coactivator in the splicing of SRm160/300-dependent pre-mRNAs.
Evaluation of liquid chromatography coupled with high‐field 1H NMR spectroscopy for drug metabolite detection and characterization: The identification of paracetamol metabolites in urine and bile

The applicability of coupled reversed‐phase high performance liquid chromatography (HPLC)‐NMR spectroscopy for the detection and identification of paracetamol (N‐(4‐hydroxyphenyl)acetamide) and its sulfate, glucuronide and N‐acetylcysteinyl metabolites in the unprocessed biological fluids, human urine, rat urine and rat bile, is investigated. Analysis of these samples was performed by gradient HPLC elution and directly coupled 500 MHz 1H NMR spectroscopy detection using a combination of one‐ and two‐dimensional NMR methods in stopped‐flow mode. The stopped‐flow approach is demonstrated to be an efficient technique for identification of drug metabolites which have, for example, a UV‐chromophore. Stopped‐flow HPLC analysis with NMR detection is a viable technique and halting the chromatographic process several times during a run has a negligible effect on the separation and NMR characterization. The post‐acquisition data processing method of 'quantified maximum entropy' is shown to provide a means of improving the quality of spectra for minor components, thus aiding NMR resonance assignments.
The Validity of Herzberg’s Dual-Factor Theory on Job Satisfaction of Political Marketers

An avalanche of studies has been conducted to determine the level of job satisfaction, and determinants thereof, among political marketers – including political party supporters. Majority of these studies utilized the Maslow theory, which is based on a hierarchy of needs. Maslow’s theory has severally been criticized on philosophical, methodological and hierarchical grounds. The theory argues that human needs are ordered, i.e. they range from lower-order to higher-order needs. As one need is adequately or partially fulfilled, the individual moves to the next higher-order need. By so doing, an individual is said to derive his job satisfaction. But Herzberg’s two-factor theory (also called motivation /Hygiene theory) has been suggested as a more plausible alternative to the Maslow’s Theory for studying job satisfaction, and in evaluating the previous research efforts on political marketers which are mainly rooted in Maslow’s theory. The purpose of this paper is to present the result of an empirical investigation of the validity of the motivation – Hygiene Theory in the Nigerian political environment. The result should prove useful in evaluating the theory as an alternative to Maslow’s theory when studying job satisfaction. Key words: Motivation, Job satisfaction, Political marketers, Herzberg‘s Theory
Fatty acid characterization of rapidly growing pathogenic aerobic actinomycetes as a means of identification

The fatty acid compositions of 39 type strains and 529 clinical or reference strains of pathogenic aerobic actinomycetes were analyzed after standardized culture by using the Microbial Identification System (MIS). Library entries for each type strain were created by using the MIS Library Generation Software, and the fatty acid profiles of clinical and reference strains were compared to these library entries. The bacteria separated into two large groups based upon major amounts of branched-chain or of saturated or monounsaturated straight-chain fatty acids. Identification of isolates was possible by using only the type strains for comparison, but fatty acid heterogeneity occurred within most species.
Harvesting and summarizing user-generated content for advanced speech-based human-computer interaction

There have been many assistant applications on mobile devices, which could help people obtain rich Web content such as user-generated data (e.g., reviews, posts, blogs, and tweets). However, online communities and social networks are expanding rapidly and it is impossible for people to browse and digest all the information via simple search interface. To help users obtain information more efficiently, both the interface for data access and the information representation need to be improved. An intuitive and personalized interface, such as a dialogue system, could be an ideal assistant, which engages a user in a continuous dialogue to garner the user’s interest and capture the user’s intent, and assists the user via speech-navigated interactions. In addition, there is a great need for a type of application that can harvest data from the Web, summarize the information in a concise manner, and present it in an aggregated yet natural way such as direct human dialogue. This thesis, therefore, aims to conduct research on a universal framework for developing speech-based interface that can aggregate user-generated Web content and present the summarized information via speech-based human-computer interaction. To accomplish this goal, several challenges must be met. Firstly, how to interpret users’ intention from their spoken input correctly? Secondly, how to interpret the semantics and sentiment of user-generated data and aggregate them into structured yet concise summaries? Lastly, how to develop a dialogue modeling mechanism to handle discourse and present the highlighted information via natural language? This thesis explores plausible approaches to tackle these challenges. We will explore a lexicon modeling approach for semantic tagging to improve spoken language understanding and query interpretation. We will investigate a parse-and-paraphrase paradigm and a sentiment scoring mechanism for information extraction from unstructured user-generated data. We will also explore sentiment-involved dialogue modeling and corpus-based language generation approaches for dialogue and discourse. Multilingual prototype systems in multiple domains have been implemented for demonstration.

Phylogenetic Relationships Among Species of Lutzomyia, Subgenus Lutzomyia (Diptera: Psychodidae)

ABSTRACT Lutzomyia França is the largest and most diverse sand fly genus in the New World and contains all the species involved in the transmission of American visceral leishmaniasis (AVL). Morphological characters were used to test the monophyly and to infer phylogenetic relationships among members of the Lutzomyia subgenus. Fifty-two morphological characters from male and female adult specimens belonging to 18 species of Lu. (Lutzomyia) were scored and analyzed. The resulting phylogeny confirms the monophyly of this subgenus and reveals four main internal clades. These four clades, however, do not support the classification of the subgenus in two series, longipalpis and cavernicola, because neither is necessarily monophyletic. Knowledge on phylogenetic relationships among these relevant vectors of AVL should be used as a tool for monitoring target taxa and a first step for establishing an early warning system for disease control.
The Effects of Thoracic Epidural Anesthesia on Functional Recovery from Myocardial Stunning in Propofol-Anesthetized Dogs

The purpose of this investigation was to examine the effects of thoracic epidural anesthesia (TEA) on myocardial stunning during propofol anesthesia.Six dogs were chronically instrumented for measurement of left atrial, aortic, and left ventricular pressure, maximal rate of increase of left ventricular pressure, and myocardial wall-thickening fraction (WTF). Myocardial blood flow was determined with colored microspheres. Experiments were performed on separate days with 1) 10 min of left anterior descending artery (LAD) ischemia during propofol anesthesia without TEA, and 2) 10 min of LAD ischemia during propofol anesthesia with TEA. WTF was measured as baseline (BL) prior to propofol anesthesia and at predetermined time points until complete recovery from stunning. Propofol anesthesia caused a significant decrease of WTF in the LAD-perfused myocardium (LAD-WTF) compared to BL in awake animals. LAD ischemia led to a further significant decrease of LAD-WTF. There were no significant differences in LAD-WTF between the two experimental conditions at any of the time points measured. TEA did not change subendocardial blood flow in nonischemic myocardium. During ischemia neither the subendocardial/subepicardial nor the occluded/normal zone blood flow ratio were affected by TEA. After myocardial ischemia during propofol anesthesia TEA does not affect functional recovery of stunned myocardium in dogs. (Anesth Analg 1997;84:723-9)
Iterative learning control for manipulator trajectory tracking without any control singularity

In this paper, we investigate trajectory tracking in a multi-input nonlinear system, where there is little knowledge of the system parameters and the form of the nonlinear function. An identification-based iterative learning control (ILC) scheme to repetitively estimate the linearity in a neighborhood of a desired trajectory is presented. Based on this estimation, the original nonlinear system can track the desired trajectory perfectly by the aid of a regional training scheme. Just like in adaptive control, a singularity exists in ILC when the input coupling matrix is estimated. Singularity avoidance is discussed. A new parameter modification procedure for ILC is presented such that the determinant of the estimate of the input coupling matrix is uniformly bounded from below. Compared with the scheme used for adaptive control of a MIMO system, the proposed scheme reduces the computation load greatly. It is used in a robotic visual system for manipulator trajectory tracking without any information about the camera-robot relationship. The estimated image Jacobian is updated repetitively and then its inverse is used to calculate the manipulator velocity without any singularity.
Generalization of example movements with dynamic systems

In the past, nonlinear dynamic systems have been proposed as a suitable representation for motor control. It has been shown that it is possible to learn desired complex control policies by a nonlinear transformation of an existing simpler control policy, which is based on a canonical dynamic system. The resulting control policies were termed dynamic movement primitives. The main result of this paper is an approach to learning parametrized sets of dynamic movement primitives based on a library of example movements. Learning was implemented by applying locally weighted regression where the goal of an action is used as a query point into the library of example movements. The proposed approach enables the generation of a wide range of movements that are adapted to the current configuration of the external world without requiring an expert to appropriately modify the underlying differential equations to account for percepetual feedback.
Working with the media in Peru.

The Peruvian Institute of Responsible Fatherhood (INPPARES) organizes an annual meeting for the media to present information on family planning (FP) and population issues and to influence public opinion. In addition, awards are presented acknowledging outstanding journalistic achievements in the area of FP. INPPARES has also organized three national journalist contests. This communication strategy has resulted in nationwide coverage of the issue on radio and television with experts in science and the health field. A number of stories related to FP have also appeared in the largest daily newspapers and magazines. A series of interviews were disseminated through Radio Comas, Radio El Sol, and Radio Victoria promoting the services of INPPARES. The magazine Telecolor published weekly articles written by INPPARES professionals promoting the services offered at the clinics. In 1993 these articles dealt with vasectomy, tubal ligation, adolescent pregnancy, and taboos of human sexuality. The newspaper Ojo published 56 eight-page supplements in 1995 on vasectomy, mortality due to pregnancy-related causes, and maternal mortality in the third world. The Rosa Cisneros Memorial Information Award of the International Planned Parenthood Federation aroused the interest of the country's journalists to focus on the issue of FP with some of them even specializing in this area of interest. INPPARES as a distinguished FP association received this award in 1995 for its efforts in communications. INPPARES also facilitates the access of low-income people to FP services. The attendant US$5000 prize was divided between the winners of the media and FP association categories.
Redesigning postnatal care: a randomised controlled trial of protocol-based midwifery-led care focused on individual women's physical and psychological health needs.

OBJECTIVES To develop, implement and test the cost-effectiveness of redesigned postnatal care compared with current care on women's physical and psychological health. DESIGN A cluster randomised controlled trial, with general practice as the unit of randomisation. Recruited women were followed up by postal questionnaire at 4 and 12 months postpartum and further data collected from midwife and general practice sources. SETTING Thirty-six randomly selected general practice clusters in the West Midlands Health Region, UK. PARTICIPANTS All women expected to be resident within recruited practices for postnatal care were eligible for inclusion. Attached midwives recruited 1087 women in the intervention and 977 in the control practice clusters. INTERVENTIONS The systematic identification and management of women's health problems, led by midwives with general practitioner contact only when required. Symptom checklists and the Edinburgh Postnatal Depression Scale (EPDS) were used at various times to maximise the identification of problems, and individual care and visit plans based on needs. Evidence-based guidelines were used to manage needs. Care was delivered over a longer period. MAIN OUTCOME MEASURES Women's health at 4 and 12 months, assessed by the Physical and Mental Component Scores (PCS and MCS) of the Short-Form 36 (SF-36) and the EPDS. Women's views about care, reported morbidity at 12 months, health service usage during the year, 'good practice' indicators and health professionals' views about care were secondary outcomes. RESULTS At 4 and 12 months postpartum the mean MCS and EPDS scores were significantly better in the intervention group and the proportion of women with an EPDS score of 13+ (indicative of probable depression) was significantly lower relative to controls. The physical health score (PCS) did not differ. Health service usage was significantly less in the intervention group as well as reported psychological morbidity at 12 months. Women's views about care were either more positive or did not differ. Intervention midwives were more satisfied with redesigned care than control midwives were with standard care. Intervention care was cost-effective since outcomes were better and costs did not differ substantially. CONCLUSIONS The redesigned community postnatal care led by midwives and delivered over a longer period, resulted in an improvement in women's mental health at 4 months postpartum, which persisted at 12 months and at equivalent overall cost. It is suggested that further research should focus on: the identification of postnatal depression through screening; whether fewer adverse longer term effects might be demonstrated among the children of the women who had the intervention care relative to the controls; testing interventions to reduce physical morbidity, including studies to validate measures of physical health in postpartum women. Further research is also required to investigate appropriate postnatal care for ethnic minority groups.
Theory and comparison of the linear stator permanent magnet vernier machine

The purpose of this paper is to describe a theory study of the linear stator permanent magnet vernier (LSPMV) machine. The fundamental operating principle, design criteria, characteristics and performances of the machine are discussed in this paper. In order to confirm the advantages, a quantitative comparison between the LSPMV machine and the linear vernier hybrid (LVH) machine is performed under the conditions of the same magnetic loading, electric loading and rated speed by using the finite element method. The results show that the proposed machine has higher power density and lower cogging force than the LVH machine.
