Feature selection is required in many applications that involve high dimensional model building or classification problems. Many bioinformatics applications belong to this type. Recently, some approaches for supervised and unsupervised feature selection as a multi-objective optimization problem have been proposed. As the performance of unsupervised classification is evaluated through the quality of the obtained groups or clusters in the data set to be classified, it is difficult to define a suitable objective function that drives the selection of the features. Thus, several evaluation measures, and thus multi-objective clustering characterization, could provide a suitable set of features for unsupervised classification. In this paper, we consider the parallel implementation of a multi-objective feature selection that makes it possible to apply it to complex classification problems such as those having many features to select, and specifically high-dimensional data sets with much more features than data items. In this paper, we propose master-worker implementations of two different parallel evolutionary models, the parallel computation of the cost functions for the individuals in the population, and the parallel execution of evolutionary multi-objective procedures on subpopulations. The experiments accomplished on different benchmarks, including some related with feature selection in classification of EEG (Electroencephalogram) signals for BCI (Brain Computer Interface) applications, show the benefits of parallel processing not only for decreasing the running time, but also for improving the solution quality.


A series of experiments that combined thermal analysis and interrupted solidification was carried out to understand the solidification behavior of type 308 stainless steel weld metal. Results indicate the following sequence of phase separations for the alloy investigated: L ..-->.. L + delta ..-->.. L + delta + ..gamma.. ..-->.. ..gamma.. + delta. Ferrite observed at room temperature was identified as the untransformed primary delta-ferrite that formed during the initial stages of solidification. The mode of freezing and the extent of solid-state diffusion both control the amount and distribution of ferrite. Microstructural and microprobe analyses indicated both extensive solid-state transformation and solute redistribution during solidification and cooling from the nonequilibrium solidus to room temperature.


A new active system for reduction of rolling noise produced at tire‐ground contact is proposed. The system is constituted by acoustical emitters installed on the car mudguard close to tire‐ground point of contact. Active control is achieved by means of an electronic control unit which generates the control signal according to a digital error minimization technique. The active system has been tested on a stationary condition by means of an original experimental facility built at Acoustic Laboratory of the University of Perugia. The facility reproduces the acoustical emission of rolling noise employing a recorded noise source. Experimental tests show that the proposed active noise control system is particularly suitable for rolling noise low‐frequency components attenuation. Application on a traveling car is actually going on.


We analyse the graphs produced by 93 prospective primary school teachers in an open statistical project where they had to compare two statistical variables. We classify the graphs according its semiotic complexity and analyse the teachers' errors in selecting and building the graphs as well as their capacity for interpreting the graphs and getting a conclusion on the research question. Although about two thirds of participant produced a graph with enough semiotic complexity to get an adequate conclusion, half the graphs were either inadequate to the problem or incorrect. Only one third of participants were able to get a conclusion in relation to the research question.


The open collaborative characteristics of online encyclopedia and the large number of ambiguity phenomena in the encyclopedia entry lead to inappropriate classification of plenty of Infobox knowledge triples of entries, which requires for refining and denoising of large-scale knowledge to improve the precision of Knowledge Base (KB). The enormous amount of triples in the KBs will cause excessive serial computing time expenditure by knowledge denoising and disambiguation processing. Existing knowledge refinement and disambiguation techniques have limitations in terms of scalability and time-efficient. There is still few typical research on the parallel processing of knowledge refinement in distributed environment. Therefore, this paper proposes a novel parallel algorithm for Chinese large-scale knowledge refinement based on MapReduce to further improve the overall system computing speed through parallel optimization for serial algorithm. Based on the original serial refining algorithm which can enhance the precision of encyclopedia-oriented KBs, results show that the novel parallel denoising algorithm proposed in this paper can further provide the system with good scalability and high speedup.

This paper introduces component based finite element model (CBFEM) which is a new method to analyse and design connections of steel structures. Design focused component model (CM) is compared to finite elements models (FEM). Procedure for composition of a model based on usual production process is used in CBFEM. Its results are compared to those obtained by component method for portal frame eaves moment connection. Design of moment resistant column base is demonstrated by a case loaded by two directional bending moments and normal force. Interaction of several connections in one complex joint is explained in the last example.


Abstract The selective conversion of methane to methanol remains one of the holy grails of chemistry, where Cu‐exchanged zeolites have been shown promote this reaction under stepwise conditions. Over the years, several active sites have been proposed, ranging from mono‐, di‐ to trimeric CuII. Herein, we report the formation of well‐dispersed monomeric CuII species supported on alumina using surface organometallic chemistry and their reactivity towards the selective and stepwise conversion of methane to methanol. Extensive studies using various transition alumina supports combined with spectroscopic characterization, in particular electron paramagnetic resonance (EPR), show that the active sites are associated with specific facets, which are typically found in γ‐ and η‐alumina phase, and that their EPR signature can be attributed to species having a tri‐coordinated [(Al2O)CuIIO(OH)]− T‐shape geometry. Overall, the selective conversion of methane to methanol, a two‐electron process, involves two monomeric CuII sites that play in concert.


BACKGROUND
The assessment of quality of life (QOL), identifying functional capacity and frequency of angina and other cardiac symptoms, are key issues in the treatment of chronic patients or in those with disease instability.

OBJECTIVE
To identify predictors of quality of life (QOL) improvement in patients with non-ST segment elevation acute coronary syndrome (NSTEACS).

METHODS
Patients hospitalized in a cardiology reference hospital were assessed with the Seattle Angina Questionnaire (SAQ) at the time of admission and after 6 months. The analyzed outcome was the variation of the QOL score, resulting from the difference between the score after six months and the score at the time of admission. Differences between patients with or without 6-month QOL improvements regarding the demographic, clinical and therapeutic characteristics were assessed by univariate and multivariate analysis.

RESULTS
Hypertensive patients presented lower improvement in QOL scores when compared to non-hypertensive ones [8.3(0-25) vs. 16.6(0-33.3); P=0.05], as well as patients with dyslipidemia, when compared to non-dyslipidemic ones [8.3(0-25) vs. 16.6(0-33.3); P=0.02]. Patients with unstable angina presented greater improvements in QOL in relation to those with NSTE myocardial infarction [16.6(0-33.3) vs. 8.3(-8.3-25); P=0.03]. By multivariate analysis, myocardial revascularization in the first 30-days was associated with the greater improvement in the QOL score (8.47 points; P=0.005). On the other side, the presence of dyslipidemia at the baseline evaluation was an independent predictor of worse QOL scores (-7.2 points; P=0.01).

CONCLUSION
Myocardial revascularization was associated with improvement in the 6-month QOL scores, while dyslipidemia was associated with worse scores.


Wetlands are defined as water systems with marsh or fen and with water that is static or flowing, fresh or brackish, the depth of which at low tide is below 6m [5]. Natural wetlands are characterized by emergent aquatic vegetation such as cattails (typha), rushes (Scirpus) and reeds (Phragmites), and by submerged and floating plant species. Wetlands are categorized into three main categories: (1) fresh water coastal wetlands, (2) flood – plain wetlands and (3) constructed wetlands. These are valuable ecosystems as they support services which contribute significantly to human well being. Some of these services are fish and fiber, water supply, water purification, flood regulation, recreational opportunities and tourism.

Abstract : The combination of artificial intelligence (AI) and database technology allows the capability of extending the usefulness of existing database applications. More specifically, the use of AI provides the means to develop an intelligent front end to allow nonintrusive assess to multiple relational databases. A knowledge source is built for each participating database application. A meta-knowledge source, constructed from all knowledge sources in the system, is consulted to determine the appropriate application to which a database request is channeled. This report introduces a proposed architecture and presents a prototype developed to accomplish this task....

This is a collection of 18 essays, with a unified list of references, in a special issue of the AKS-Rundbrief. The majority of the essays are focused on practical uses of the so-called C-test procedure. Eight of them are in German, but a reader unfamiliar with German can acquire most of the essential information from the 10 that are in English. It seems that the situation in language testing leading to the development of the C-test has been this: we know fairly well how to make various kinds of language tests of both the discrete-point and integrative varieties, even covering 'communicative competence', but making such tests is usually arduous and time consuming, requiring extensive procedures of item analysis and validation. Many such tests are sometimes difficult to administer and score. Further, all sorts of questions can be raised about these tests, even when much devoted effort has been spent on their construction. Language testers have therefore long sought relatively simple, easy and inexpensive ways of constructing reliable and valid tests for practical use. One such way has been the close test method as developed originally by Taylor ( 1953) for measuring readability of prose but later widely adapted for testing language competence, both in first languages and in second languages. But even the standard cloze test has not been without


The year 2022 has been one of hybrid events all over the world, as we emerge from the effects and aftereffects of COVID-19. With the repercussions still lingering, there are many aspects that need to be addressed before announcing any event. We are geared up to attend the 2022 IEEE Antennas and Propagation Society (AP-S) International Symposium on Antennas and Propagation/U.S. National Committee–International Union of Radio Science Meeting in Denver, Colorado, from 10 to 15 July 2022. In August, when you will be reading this issue's "COPE Corner" column, we hope that we will have met in person at the IEEE symposium and will have many more topics to share.


Purpose: Studies have reported faster cognitive/functional decline in persons with dementia (PWD) with malnutrition. We investigated whether baseline nutritional status predicted severe dementia and mortality in a population-based sample. Patients: A maximum of 300 PWD were assessed annually for up to 8.6 years. Methods: Nutritional status was assessed using a modified Mini-Nutritional Assessment (mMNA). Severe dementia was defined as: "severe" rating on the Clinical Dementia Rating or Mini-Mental State Examination score ⩽10. Using Cox proportional hazards models, we examined the association between baseline mMNA score (or its subcomponents) with each outcome. Covariates included demographics; dementia onset age, type, and duration; APOE genotype; and residency with caregiver. Results: Compared with "well-nourished," "malnourished" PWD had 3-4 times the hazard of severe dementia [hazard ratio (HR), 4.31; P=0.014] and death (HR, 3.04; P<0.001). Those "at risk for malnutrition" had twice the hazard of severe dementia (HR, 1.98; P=0.064) and 1.5 times the hazard of death (HR, 1.46; P=0.015). mMNA subcomponents of food group intake, weight loss, body mass index, mobility, health status, protein consumption, and mid-arm circumference predicted one or both outcomes. Conclusions: Nutritional status is an important predictor of clinical outcomes in dementia and may provide an avenue for intervention.


Information and communication technology (I.C.T.) has become, within a very short time, one of the basic building blocks of modern society. The role of I.C.T. in teaching and learning is rapidly becoming one of the most important and widely discussed issues in contemporary education policy. As a result, the role of the teacher is very important in rolling out this innovation (integrating ICT into the curriculum). This is because teachers are at the centre of curriculum change and they control the teaching and learning process. Therefore, they must be able to prepare the young generation for the current technology in which the competency to use ICT to acquire and process information is paramount. This book investigates History teachers' perception and their usage of information and communication technology to improve teaching and learning of History.


A multi-frequency acoustic zooplankton fish profiler (AZFP, ASL Environmental Sciences) with temperature-salinity and depth sensor was moored at 10 m from the bottom (ca. 30 m) at the mouth of Yamada Bay in Iwate Prefecture, Japan, from 14 January to 16 June 2015 in order to measure volume backscattering strength profiles from the transducer surface to the water surface at four frequencies (125, 200, 455, and 769 kHz). Zooplankton density by size was estimated from the measured volume backscattering strength at four frequencies by the inversion method. Monitoring period was selected to cover the period when juvenile salmon stay in the bay before leaving for oceans. Zooplankton sampling was conducted periodically (once a week or two weeks, day and night) using a Kitahara Net (30 cm dia., 335 µm mesh) and a Norpac Net (45 cm dia., 335 µm mesh) at near the moored position. These observations revealed that large zooplankton, which juvenile salmon prefers, arrived with the Oyashio Current, and the zooplankton ...


Background: Budd Chiari Syndrome denotes a group of rare diseases which have been studied with considerable interest by clinicians across the world. The clinical presentation and investigation results vary in most cases making the diagnosis a challenge. Although the treatment protocols are published in literature, much of it comes from expert opinions rather than research-based findings. The use of medical therapy, thrombolysis and interventional procedures are well known. However, the order of preference while choosing the treatment option depends on each case and must be considered depending on local expertise. Case Summary: We present a case of a young male patient with no significant medical history who presented with lower limb oedema and pain. The laboratory findings were within normal range and the ultrasound scan revealed mild hepatomegaly. On further imaging we found a retrohepatic vena caval occlusion which was amenable to endovascular intervention. This patient was treated with angioplasty and stenting with satisfactory clinical outcome. The decision to proceed with an endovascular first approach is highlighted in our case report. Conclusion: The traditional treatment strategies for BCS include medical therapy, thrombolysis or surgical portosystemic shunt creations which involve significant morbidity and procedure related Case Study Sadia et al.; AJRRHE, 3(1): 11-15, 2021; Article no.AJRRHE.66077 12 complications. It is worthwhile to select patients with amenable lesions to undergo endovascular treatment in the initial stages of management. This will lead to good clinical outcomes and prevent long term liver damage. This approach has been highlighted in our case report and we recommend its use with the availability of local expertise.


In this paper, models of the blood glucose (BG) dynamics in people with Type 1 diabetes (T1D) in response to moderate intensity aerobic activity are derived from physiology-based first principles and system identification experiments. We show that by enhancing insulin-dependent glucose utilization by the tissues in two phases, a rapid short-term increase in insulin-independent glucose clearance and augmented glucose uptake, and a long-term sustained increase sensitivity to insulin action, a metabolic model able to reproduce the effects of activity on glucose disposal is obtained. Second, a control-oriented transfer function model is proposed to predict the BG response to an exercise bout modeled as a step change in heart rate (HR). Results comparing model predictions with actual patients data collected in a series of experimental sessions including physical activity (PA) are presented. The findings will contribute to the design of a fully automated closed-loop for improved glucose control in conditions of daily life for people with T1D.


In the mining tax system of foreign countries,royalties are the major form of production rights of mineral resources;and in the formulation and implementation of mining tax system,the incentive systems of mineral resources exploration and exploitation are blended in.This paper analyses some alienations in the evolution process of the mining tax system in China,these show up in: the explanation of resource tax is against that of land rent theory;the economy benefit relationship of mineral resource compensation fee does not reflect in place;the price of mining rights are seriously alienated.On account of this,this paper proposes some specific methods for promoting the reform of resource tax system,these include: the relations between the various economic sectors should be straightened out,while the reform of resource tax system should be pushed forward in a coordinated way;the reform of mineral resource compensation fee should be accelerated;the price of mining rights and the nature of royalty,as well as reform price and royalty system must be clearly defined;the excess rent tax system of resources must be established.

Objectives Shift work is associated with various health challenges, including obesity and metabolic disturbances. To address these concerns, a randomised controlled clinical trial was conducted to evaluate the efficacy of a low-calorie meal replacement (MR) dietary intervention for dinner among shift workers with obesity. This study focuses on the qualitative aspects of this intervention, aiming to explore the experiences and perceptions of shift workers who participated in the trial. Design Following the completion of the intervention, semi-structured face-to-face or telephone interviews were conducted with a purposive sample of trial participants. Data analysis was inductive, thematic using NVivo V.10 software. Setting The intervention was conducted among shift workers with obesity in a private hospital in Sri Lanka and resulted in a modest decrease in weight. Participants Using purposeful maximum variation sampling, we recruited eight healthcare shift workers who took part in a weight loss intervention. Results All participants expressed satisfaction with the MR meal for dinner, highlighting its positive impact on their well-being. Despite initial difficulties, strong determination and motivation by results supported adherence. Some participants suggested that the MR could be improved with sweeter taste and more flavour options. Few reported mild bloating at the beginning, but no serious side effects were noted. Participants felt lighter in their bodies due to weight loss. The method's simplicity was the most frequently reported benefit, making it feasible even during busy night shifts. Overall, participants highly recommended the intervention to others in need. Conclusion Participants experienced weight loss by replacing their dinner with the MR. This study offers valuable insights for tailoring future workplace-based dietary interventions for this vulnerable population. Trial registration number ACTRN12622000231741.


Many Earth‐Mars cycler trajectories are now known and their numbers continue to grow. Unfortunately, the literature on Earth‐Mars cycler trajectories uses many different systems for naming the various cyclers being investigated. A nomenclature is proposed as a remedy to standardize the naming system for near-ballistic Earth‐ Mars cycler trajectories. Modeling assumptions are given and the proposed nomenclature is explained. All known near-ballistic cyclers fall within the scope of the described nomenclature. Examples are presented of how several well-known cyclers are denoted. The syntax of the nomenclature is formally specified using the extended Backus‐ Naur form. Criteria for evaluating Earth‐Mars cycler trajectories are summarized.


Raw milk is a nutrient-rich food that is considered a high-quality nutritional medium for many microorganism, including Escherichia coli. The aim of the present work was the diagnosis, by molecular methods, of Shiga toxins produced by E. coli strains isolated from cow milk samples collected from different farms in Al-Mahmmodia, Al yoosifya, Al lattiffya, Al howasha, and Arab Jboor in the government of Baghdad during the summer season. Milk samples were incubated in media for bacterial isolation. Isolates were identified using Gram staining and biochemical tests. Out of 50 samples, 15 (30%) showed the presence of E. coli. To confirm the identity of the isolates, their 16S rRNA genes were amplified using specific primers. The results showed that all isolates were E. coli. Shiga toxin-producing E. coli (STEC) were detected among the samples. The prevalence of stx1 genes was higher than that of stx2 among them. No STECs were found among six of the sample isolates, and none of these isolates was positive for stx1 and stx2. SDS-PAGE was used to determine the molecular weight of the toxin, and four selected E. coli bacteria producing Shiga-like toxins showed a clear band of approximately 70 kDa.

Spatiotemporal patterns in soil moisture and vegetation water content across mainland Australia were investigated from 1998 through 2005, using TRMM/TMI passive microwave observations. The Empirical Orthogonal Function technique was used to extract dominant spatial and temporal patterns in retrieved estimates of moisture content for the top 1‐cm of soil (θ) and vegetation moisture content (via optical depth τ). The dominant temporal θ and τ patterns were strongly correlated to the El Niño Southern Oscillation Index (SOI) in spring (r2 = 0.90), and to a progressively lesser extent autumn, summer and winter. The Indian Ocean Dipole (IOD) index also explained part of the variation in spring θ and τ. Correlation analysis suggested that the regions most affected by El Niño are mainly located in eastern Australia. The results suggest that the drought conditions experienced in eastern Australia since 2000 and clearly expressed in these satellite observations have a strong connection with El Niño.


The members of the Committee on Glaciers for 1935 are as given in the report of the Committee for 1933–34 in the Transactions of the Fifteenth Annual Meeting with the addition of Kenneth N. Phillips (The Mazamas, Pacific Building, Portland, Oregon).

The year 1934 witnessed a further expansion of the program of systematic annual observations on the variations of American glaciers which was inaugurated by the Committee in 1931. Several of the collaborators in the field-work of their own initiative enlarged the scope of their activities, and a new group joined the movement in the Pacific Northwest, These are the Mountaineers, of Seattle, Washington, who began observations on the glaciers of Mount Baker, which are the largest in the continental United States next to those on Mount Rainier. Under the leadership of H. V. Strandberg a base-line was laid out by the Mountaineers for measurement of the recession of the Easton Glacier, on the south side of the peak.


This research project explored the nexus between historical literacies, digital literacy and m-learning as a praxis of mobilizing technopolitics. To do this, we developed a mobile application for teacher candidates to study the absence of the Indian Residential School system as a complement to history textbooks and other curricular materials. Building on the findings of our SSHRC-funded digital history research project, we sought to engender a "technopolitics" as a form of critical historical literacy. Out of this work, we sought to understand how digital technologies contributed to recent calls to mobilize educational research and more specifically, while working to decolonize existing narratives of Canadian history beyond traditional modes of dissemination.


The aim of this work is to establish a novel linear instability criterion for the Korteweg–de Vries (KdV) model on metric graphs. In the case of balanced graphs with a structure represented by a finite collection of semi-infinite edges and with boundary condition of δ-type interaction at the graph-vertex, we show that the continuous tail and bump profiles are linearly unstable. In this case, the use of the analytic perturbation theory of operators as well as the extension theory of symmetric operators is fundamental in our stability analysis. The arguments showed in this investigation have prospects in the study of the instability of stationary waves solutions for nonlinear evolution equations on metric graph.


Practical solutions have not been obtained from the previous papers addressing the problem of testing intermittent faults in sequential circuits. Existing methods are only suitable for small sequential circuits. This correspondence presents a new technique to design test-experiments for intermittent faults which can conveniently be used for relatively more complex synchronous sequential circuits.


Regional data of groundwater levels for wells in the Lake Karachai area are presented. A method to analyze these data is proposed for the evaluation of hydrological parameters of fractured rocks in this area. The calculated parameters are used to obtain volume losses as a result of filtration into the bed of Lake Karachai, which are then compared with direct data.


Proteases are present in all forms of life, they are produced by microorganisms, various plants and animals. Among them bacterial proteases secure most important place due to their enormous industrial applications. They represent one of the largest groups of industrial enzymes and find application in detergents, leather, food, pharmaceutical and textile industries as well as silver recovery and bioremediation processes. The largest application of protease is in laundry detergents and leather industry, where they remove protein based stains from clothes and dehairing purpose, respectively. As the modern world focuses on ecofriendly products and product output, subsequently more chemical processes are being replaced by enzymatic methods. Today there is a need for new, improved and/or more versatile enzymes in order to develop more novel, sustainable and economically competitive production processes. In this review, some protease producing bacteria and protease classification as well as the techniques to enhance productivity of protease are discussed. The production of bacterial proteases using cheap and readily available substrates is delineated. The use of bacterial proteases in diverse industrial applications is also discussed. Finally, future prospects are proposed.


In medicine, the study of anatomy is of utmost importance since this fundamental course is relevant to all medical careers. Every single medical student must learn anatomy regardless of which specialization they choose to follow. Technology‐assisted learning is a growing topic not only in medicine, but in each and every area of study. There is a large number of possible approaches to teach/learn assisted by technology such as educative and serious games, the use of virtual and augmented reality, hardware and software created specifically for training a certain skill and many more. Based on this approach, in this research we developed a gamified mobile application to help both the students and the professor at anatomy classes to understand and develop knowledge in this field based on different kinds of media such as videos, texts, images, audios, quizzes and so on. Gamification consists in the use of game elements in different contexts outside games. This involves presenting aspects such as ranking, badges, quests, etc. to promote engagement and institutes an immersion and flow in faculty education. In order to do that, it was applied the Marczewski's Gamification Design Framework, which involves the definition of the problem, users, success to project and building the user journey to attain some specific behaviours, actions and emotion which can be refined to complete the process and promote learning. This framework was combined with Artificial Intelligence techniques to recognize the difficulties of each individual student and is then able to provide targeted content based on the student performance.


Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has caused the coronavirus disease 2019 (COVID‐19) pandemic. Accurate detection of SARS‐CoV‐2 using molecular assays is critical for patient management and the control of the COVID‐19 pandemic. However, there is an increasing number of SARS‐CoV‐2 viruses with mutations at the primer or probe binding sites, and these mutations may affect the sensitivity of currently available real‐time reverse transcription‐polymerase chain reaction (RT‐PCR) assays targeting the nucleocapsid (N), envelope (E), and open reading frame 1a or 1b genes. Using sequence‐independent single‐primer amplification and nanopore whole‐genome sequencing, we have found that the nonstructural protein 1 (nsp1) gene, located at the 5′ end of the SARS‐CoV‐2 genome, was highly expressed in the nasopharyngeal or saliva specimens of 9 COVID‐19 patients of different clinical severity. Based on this finding, we have developed a novel nsp1 real‐time RT‐PCR assay. The primers and probes are highly specific for SARS‐CoV‐2. Validation with 101 clinical specimens showed that our nsp1 RT‐PCR assay has a sensitivity of 93.1% (95% confidence interval [CI]: 86.2%‐97.2%), which was similar to those of N and E gene RT‐PCR assays. The diagnostic specificity was 100% (95% CI: 92.9%‐100%). The addition of nsp1 for multitarget detection of SARS‐CoV‐2 can avoid false‐negative results due to mutations at the primers/probes binding sites of currently available RT‐PCR assays.

One of interesting open questions for the high transition temperature (Tc) superconductivity in sulfur hydrides is why high pressure phases of H3S have extremely high Tc's. Recently, it has been pointed out that the presence of the van Hove singularities (vHs) around the Fermi level is crucial. However, while there have been quantitative estimates of Tc based on the Migdal-Eliashberg theory, the energy dependence of the density of states (DOS) has been neglected to simplify the Eliashberg equation. In this study, we go beyond the constant DOS approximation and explicitly consider the electronic structure over 40eV around the Fermi level. In contrast with the previous conventional calculations, this approach with a sufficiently large number of Matsubara frequencies enables us to calculate Tc without introducing the empirical pseudo Coulomb potential. We show that while H3S has much higher Tc than H2S for which the vHs is absent, the constant DOS approximation employed so far seriously overestimates (underestimates) Tc by ~ 60K (~ 10K) for H3S (H2S). We then discuss the impact of the strong electron-phonon coupling on the electronic structure with and without the vHs and how it affects the superconductivity. Especially, we focus on (1) the feedback effect in the self-consistent calculation of the self-energy, (2) the effect of the energy shift due to the zero-point motion, and (3) the effect of the changes in the phonon frequencies due to strong anharmonicity. We show that the effect of (1)-(3) on Tc is about 10-30K for both H3S and H2S. Eventually, Tc is estimated to be 181K for H3S at 250GPa and 34K for H2S at 140GPa, which explains the pressure dependence of Tc observed in the experiment. In addition, we evaluate the lowest order vertex correction beyond the Migdal-Eliashberg theory and discuss the validity of the Migdal approximation for sulfur hydrides.


The publication playing fi eld is not level for non-native users of English or for researchers in developing countries, and this problem has been discussed from many angles [1]. What can be done? Hooman Momen, director of Knowledge Management and Sharing at WHO Press (World Health Organization), has noted the recent growth in efforts to help developing-country researchers become authors, while recognising that the current capacity of these initiatives is far from suffi cient:


A theoretical analysis of excitation, transmission, andreception of surface skimming bulk waves(SSBW)by a pair of interdigital electrodes on rotated Y-cut quartz has been performed. Because quartz is relatively weakly piezoelectric, solutions to the Christoffel equations decouple to first order into purely acoustic and electrostaticwaves. When a time-varying voltage is appliedto a set of interdigital electrodes, it is found that each Fourier component of the induced electrostatic potential is coupled to a phase-matched outward propagating acoustic plane wave through the requirementof zero normal surface stress. By integrating the acoustic power density overkspace, a simple analytical expression for the radiation resistanceis obtained in terms of the material and transducer parameters. An asymptotic integration of the Fourier-components of the acoustic wave amplitude leads through the method of saddle-point integration to a closed-form expression for acoustic wave amplitude and far-field radiation pattern. Reciprocity is used to obtain closed form expressions for insertionloss.


t will be demonstrated that light extraction of GaNcan be more efficient with the use of flat and dome epoxy. Theoretically the angle, wavelength, and thickness depend on the photoluminescence emission of the luminescent film of transparent substrate. This was studiedusing theFresnel type transmittance calculations for s- (TE) and p- (TM) polarized emission. Experimentally we have demonstrated a GaN/sapphire microcavity exhibited in the 1.3-1.6 fold enhancement in light extraction efficiency by using flat and dome epoxy as external medium compared with air external medium. In addition, simulation results shows that using (HfO2(), Epoxy (),MgF2 (), Air ()) improve the light extraction by increasingthe critical angle and diffracting the internal light with a large solid angle into the light escape cone.


The unlawful slaughter of black bodies by the hands of power has continued day after day, year after year, century after century, life by precious life, since before the first chain was slipped around black wrists.


This paper presents a strategy for robust H2/H∞ dynamic outputfeedback control synthesis, with regional pole placement, applied to linear continuous-time time-invariant systems with polytope-bounded uncertainty. The proposed synthesis approach is based on a multiobjective optimization algorithm applied directly in the space of controller parameters. The H2 and H∞ norms, computed in all polytope vertices and in possible "worst case" interior points are taken as the optimization objectives. A branch-and-bound algorithm based on LMI guaranteed cost formulation is applied to validate the controller design. Examples are presented to show the effectiveness of the proposed strategy, including examples of full order and low order, centralized and decentralized control systems. Copyright c ©2005 IFAC.


In 1968, the Alaska Department of Highways constructed its first experimental installation of expanded plastic foam for frost heave control at a site 11 mi south of Anchorage. This was followed, in 1969, by construction of both the first insulated roadway section over permafrost in North America at a site near Chitina, and the first insulated airfield runway at Kotzebue. Since that time, six additional roadway sections on permafrost, totalling 3.6 lane-mi, have been insulated by the Alaska Department of Transportation, along with four additional airport installations. Applications of insulation for frost heave control have been numerous, totalling 11 lane-mi. Materials used for subgrade insulations have been primarily extruded-expanded polystyrene foam (Dow's Styrofoam HI and UCI Foamular) with one installation of polyurethane foam and three of molded polystyrene beadboard. Evaluations of the long-term thermal performance of these installations have included sampling and testing of the insulations to determine the retained thickness, thermal conductivity, and compressive strength properties. Based on these observations, foamed-in-place polyurethane insulation is not accepted for use as a subgrade insulation by the Department of Transportation, whereas extruded polystyrene insulation has demonstrated superior performance and longevity. Molded polystyrene beadboard insulation layers have given acceptable performance, but must be installed at a thickness 30 percent to 50 percent greater than the extruded polystyrenes to provide comparable thermal performance. Comparisons were made between measured late summer permafrost thaw depths for insulated airfields, and calculated thaw depths using the Modified Berggren calculation method and actual site soil and insulation properties. These commparisons demonstrated that this method of calculation results in calculated thaw depths slightly greater than the actual values, but provides reasonable values for a conservative design.


We demonstrate that a popular method of estimating underlying structural macroeconomic shocks and their impulse-response functions through recursive long-run structural restrictions on a vector autoregressive representation is not uniquely identified. We show, however, that it may be possible to infer additional qualitative restrictions to achieve identification. We illustrate with two applied examples, corresponding to a simple aggregate supply-aggregate demand framework for the USA and to a stochastic Mundell-Fleming-Dornbusch framework for the USA and Japan. The second example also illustrates how over-identifying restrictions of the underlying framework may be examined informally. Copyright © 2004 John Wiley & Sons, Ltd.

This study was aimed to synthesis Ag2O nanoparticles (N.P.s) utilizing the Ginger plant (Zingiber officinale) extract. As catalysts for pyran derivatives formation employing a three-component coupling reaction among aromatic and aliphatic aldehydes, malononitrile, and dimedone. The nanoparticles exhibit robust catalytic activity with high productivity. Results revealed that Ag2O NPs improved various vital features, like higher yields, reaction time, simple chemical separation, catalytic economic efficiency, and quick process. This study aimed to cyclize heterocyclic compounds to provide new hetero compounds applying nano-oxides obtained from natural (unmanufactured) sources and used in several medical, pharmaceutical, and industrial implementations. The outcomes nanoparticles were examined by Fourier Transform Infrared spectroscopy (FTIR) and transmission electron microscopy (T.E.M.); the chemical characteristics of the outcome compounds were tested by spectroscopy techniques (FTIR spectroscopy and 1H-NMR).


Increasing the operating temperature in thermal power plant will further accelerate the high temperature oxidation with the presence of water vapor. It is hypothesized that water vapor provides hydrogen that dissolves into the ferritic alloy susbstrate, hence altering their electronic state at the metal-semiconductor (oxide) interface. This study aims to quantitatively prove above postulation by comparing their Schottky's Barrier Height (SBH) in dry and wet environment. The Schottky's barrier was prepared by sputtering $\mathbf{c}_{\Gamma 2}\mathbf{o}_{3}$ onto the T91 boiler tube in high vacuum condition using RF power 150W for an hour. The $\mathbf{T}91/\mathbf{c}_{\mathbf{r}2}\mathbf{o}_{3}$ junction was then connected with platinum wire for capacitance-voltage, C-$V$ test at high temperature. The value of $V_{\mathbf{b}1}$ was used to calculate the SBH, which increase proportionately with built in voltage. It is clearly shown that the SBH value in wet condition is higher than that in dry condition by 10.3%. This is explained by the formation of space charge layer at metal/oxide interface due to dissolved hydrogen in metal, thus may change the transport property and accelerate the oxidation rate in water vapor.

Purpose
There is a need to rethink destination competitiveness research, which tends to overlook local impacts of events and new developments. Conducting pre-event research challenges researchers to move beyond analyzing competitiveness as an end (concerning strategy, tangible outcomes, economic deliverables and value for visitors) to assessing competitiveness as a beginning (through perceptions of place management and local impacts).

Design/methodology/approach
Survey research with local residents explores competitiveness pertinent to perceptions of place management and local impacts. Participation, enthusiasm and information availability are independent variables to assess whether statistically significant differences exist among residents' perceptions. In total, 454 surveys were collected; the analysis involved exploratory factor analysis and t-test.

Findings
Factor analysis revealed two factors for place management (organizational competencies; managing awareness) and local impacts (awareness of social benefits; local interest and support). Enthusiasm and information availability have stronger influences on residents' perceptions than participation in pre-event activities.

Practical implications
More emphasis needs put on ensuring information availability promotes enthusiasm, to help encourage participation. These three variables are a necessary basis for exploring residents' pre-event perceptions – a key starting point to guide decision-making through later stages of an event life-cycle.

Originality/value
Events and competitiveness studies focusing specifically on information availability and enthusiasm of residents is little-explored. By exploring these variables and extending insight on participation, this paper contributes to the literature by assessing pre-event resident perceptions of place management and local impacts (with data collected as event developments were being realized).


Spinal manipulative therapy for low back pain—time for an update We read with interest the Tools for Practice article in the April issue of Canadian Family Physician.1 In an attempt to answer the question posed by the authors, "Is spinal manipulative therapy (SMT) effective for low back pain (LBP)?" Manning and Allan state that the bottom line is "Research around SMT is poor, consistently inconsistent, and almost impossible to interpret."1 Given the high prevalence of LBP2-4 and its associated high burden to society,5 we appreciate the importance of regularly updating primary care physicians on the management of LBP. Further, we agree that research on LBP is at times difficult to interpret, often because of poor reporting and high heterogeneity of randomized controlled trials (patients, settings, treatments, outcomes).6,7 Nonetheless, several recent systematic reviews and national clinical practice guidelines (CPGs) on the treatment of acute and chronic LBP should also be considered when addressing the potential role of SMT in the treatment of patients with LBP. More important, when choosing the right therapy for the right patient, it is necessary to compare the effectiveness, risks of adverse events, and related costs of a given treatment with other commonly used approaches. Patient experience and satisfaction with care also matter to patients with back pain.8


This paper shows a general model of rectangular footings to obtain the soil minimum contact area (optimal surface) that support from 1 to n columns aligned on a longitudinal axis. The proposed model considers that the soil pressure varies linearly. The recently published models have been presented individually to obtain the soil contact area for rectangular isolated footings, rectangular combined footings that support two columns, these models present the equations, but it is not guaranteed to be the minimum area. The present research complies with the models mentioned above and can be applied to footings that support 3 or more columns, and also the minimum area is guaranteed. Also, numerical problems are shown the soil minimum contact surface for rectangular isolated footings, and rectangular combined footings that support two and three columns (unrestricted on its sides, one side restricted and two opposite sides restricted).


The ability to walk is critical for functional independence and wellbeing. The pre‐frontal cortex (PFC) plays a key role in cognitive control of locomotion, notably under attention‐demanding conditions. Factors that influence brain responses to cognitive demands of locomotion, however, are poorly understood. Herein, we evaluated the individual and combined effects of gender and perceived stress on stride velocity and PFC Oxygenated Hemoglobin (HbO2) assessed during single and dual‐task walking conditions. The experimental paradigm included Normal Walk (NW); Cognitive Interference (Alpha); and Walk‐While‐Talk (WWT) tasks. An instrumented walkway was used to assess stride velocity in NW and WWT conditions. Functional Near‐Infrared‐Spectroscopy (fNIRS) was used to quantify PFC HbO2 levels during NW, Alpha and WWT. Perceived task‐related stress was evaluated with a single 11‐point scale item. Participants were community residing older adults (age = 76.8 ± 6.7 years; %female = 56). Results revealed that higher perceived stress was associated with greater decline in stride velocity from single to dual‐task conditions among men. Three‐way interactions revealed that gender moderated the effect of perceived stress on changes in HbO2 levels comparing WWT to NW and Alpha. Attenuation in the increase in HbO2 levels, in high compared to low perceived stress levels, from the two single task conditions to WWT was observed only in men. Thus, older men may be more vulnerable to the effect of perceived stress on the change in PFC oxygenation levels across walking conditions that vary in terms of cognitive demands. These findings confer important implications for assessment and treatment of individuals at risk of mobility impairments.


The synthesis and odour properties of the new santalol analogue, methyl‐β‐santalol, are described. The additional methyl group adjacent to the hydroxyl function of the standard molecule, β‐santalol, deprives the new compound of the sandalwood note. The synthesis and the odour evaluation of this compound supports the proposed model for sandalwood fragrance as it shows that the methyl group located at the osmophoric center prevents association of the molecule with the hypothetical receptor.

The nature of the magnetic coupling between T Tauri stars and their discs determines not only the mass accretion process but possibly the spin evolution of the central star. We have taken a recently published surface magnetogram of one moderately accreting T Tauri star (V2129 Oph) and used it to extrapolate the geometry of its large-scale field. We determine the structure of the open (wind-bearing) field lines, the closed (X-ray bright) field lines and the relatively small subset of field lines that pass through the equatorial plane inside the Keplerian corotation radius and which are therefore available to accrete.

We consider a series of models in which the stellar magnetic field is opened up by the outward pressure of the hot coronal gas at a range of radii or source surfaces. As the source surface is increased, accretion takes place along progressively simpler field structures and impacts on progressively fewer sites at the stellar surface. This is consistent with the observed variation in the Ca ii IRT and He i lines which suggests that accretion in the visible hemisphere is confined to a single high-latitude spot. By determining the density and velocity of the accretion flows, we find that in order to have most of the total mass accretion rate impacting on a single high-latitude region we need disc material to accrete from approximately 7R⊙, close to the Keplerian corotation radius at 6.8R⊙.

We also calculate the coronal density and X-ray emission measure. We find that both the magnitude and rotational modulation of the emission measure increase as the source surface is increased. For the field structure of V2129 Oph which is dominantly octupolar, the emission forms a bright, high-latitude ring that is always in view as the star rotates. Since the accretion funnels are not dense enough to cause significant scattering of coronal X-ray photons, they provide only a low rotational modulation of around 10 per cent at most.


Root-knot nematodes (Meloidogyne spp.) are soil-borne pathogens that infect vegetable crops and cause major economic losses worldwide annually. Therefore, there is an urgent need for novel nematicides or biological control agents to reduce the damage caused by root-knot nematodes. In this study, we tested efficacy of the Bacillus cereus strain Bc-cm103, isolated from the rhizoplane of Cucumis metuliferus, against Meloidogyne incognita. The strain Bc-cm103 fermentation broth caused 100% mortality of the nematode second-stage juveniles (J2s) within 12 h and decreased the egg hatching rate by 40.06% within 72 h compared with sterile water. Confocal laser scanning microscopy revealed that strain Bc-cm103 formed a biofilm on cucumber (Cucumis sativus) roots, which protected the roots from the infection of M. incognita. Additionally, strain Bc-cm103 activated the defense-responsive genes PR1, PR2, LOX1, and CTR1 in cucumber. Furthermore, strain Bc-cm103 significantly reduced the appearance of root galls in pot, split-root and field tests. These results indicated that the B. cereus strain Bc-cm103 had a strong suppressive effect on M. incognita and therefore could be used as a potential biocontrol agent against this pathogen.


The expression pattern and functional interaction of proangiogenic factors in human cholangiocellular carcinoma (CCC) have not been fully defined. We therefore investigated the expression ofVEGF and TGFs-1 as weil as their respective receptors in human CCC tumor samples and further analysed their functional interaction in vitro. Expression ofVEGF, TGFs-1 and their receptors was examined by immunohistochemistry, quantitative competitive (QC) RT-PCR and ELISA. VEGF promoter analysis and identificati(Jn of transcription factors involved in promoter regulationwas investigated using transient transfection and electrophoretic mobility shift assays. Coexpression ofVEGF and TGFs-1 and its receptors in tumor cells suggests a possible functional interaction between both cytokines. In vitro studies confirmed a paracrine/autocrine stimulation of VEGF by TGFs-1 at a transcriptionallevel. Further molecular studies using 5' -deletion and mutational analysis of the human VEGF promoter revealed that TGFs-1 stimulates VEGF through Sp1-dependent transcriptional activation. These data suggest that overexpression and functional interaction ofTGFs-1 and VEGF might contribute to the "angiogenic switch" and the malignant phenotype in human CCC.


In order to improve the system performance for vehicle-to-vehicle communications over double-Rayleigh fadings,the access-point relayed inter-vehicular communication (IVC) model is proposed.The statistical properties of the receiving signal-to-noise ratio in IVC system are studied and a closed-form expression on outage probability is obtained.And based on moment generating function method,the union upper bound on average bit error rate (ASER) is derived.Simulation results show that the theoretical analysis on outage probability coincides with Monte Carlo numerical calculations well.The ASER of the relaying IVC system is decreased and the diversity gains are achieved 3 dB more at most through optimal power allocation method than equal power allocation scheme.


The ability of camels to cope with food shortage is the result of a long evolutionary process in natural conditions where food availability seasonally fluctuates. In and conditions, all the adaptive mechanisms and especially body fat mobilization strategies are of considerable importance in determining reproductive performance. In the camel, the hump is the most important fat storage place accessible to external observation. The fat around kidney is the most important internal fat storage. Adipose tissue consists of adipocytes with different sizes according to the quantity of fat globules stored in the cell. The pattern of adipocyts according to the different sizes is an important element to assess the fat storage status. The total number of adipocytes was assessed in the different patterns (n=46). Four hump patterns and three fat kidney patterns were evaluated. A significant effect of the sex and age was noted. The size of the hump was not dependant of the adipocyte patterns- The fattening potential in camel is not linked to the size of the hump. The relationships between adipocyte patterns, number of adipocytes and metabolic profiles are not clear. (Resume d'auteur)


Solutions of the 2-D Schrödinger equation across the channel using a finite element method have been implemented into a 3-D finite element (FE) ensemble Monte Carlo (MC) device simulation toolbox as quantum corrections. The 2-D FE Schrödinger equation-based quantum corrections are entirely calibration free and can accurately describe quantum confinement effects in arbitrary device cross sections. The 3-D FE quantum corrected MC simulation is based on the tetrahedral decomposition of the simulation domain and the 2-D Schrödinger equation is solved at prescribed transverse planes of the 3-D mesh in the transport direction. We apply the method to study output characteristics of a nonplanar nanoscaled MOSFET, a{10.7}-nm gate length silicon-on-insulator FinFET, investigating 〈100〉 and 〈110〉 channel orientations. The results are then compared with those obtained from 3-D FE MC simulations with quantum corrections via the density gradient method showing very similar I-V characteristics but very different density distributions.

In this paper we analyze the technical and sociocultural features permeated the actions of corporate image and identity that had emerged from business and guvernamental organizations that had appeared in the province of Pontevedra (Galicia, Spain) from the post-war until 2000. Similarly, we study the historical and artistic influences in each particular time, they had influenced the desing and implementation of these corporate identities.


at www.sexualintelligence.org=. The most recent issue I saw (#84) was posted in February 2007, and includes a lead essay on Pfizer and Viagra; issue #35 (January 2003) favorably reviews (full disclosure) my Pornography, Sex, and Feminism (Prometheus, 2002), part of which Klein makes use of in America's War on Sex (pp. 135–136). He is clearly a dogged proselytizer for sexual freedom and sexually liberal (or civil libertarian) ''good sense.'' No wonder, then, that the impassioned ''Foreword'' to Klein's book was written by ACLU Queen Nadine Strossen, the author of her own sexually liberal treatise Defending Pornography: Free Speech, Sex, and the Fight for Women's Rights (Scribner, 1995), which relies on free speech considerations to accomplish her main task and uses the same considerations to rail powerfully against abuses of sexual harassment law, for example, to stifle university lectures on sex. (That chapter might be the best in the book.) At one point in her Foreword, Strossen approvingly quotes John Stuart Mill, from his famous 1859 On Liberty, to the effect that government and society should absolutely leave the individual alone (in his or her sexual choices, too), as long as the individual poses no threat or causes no harm to specifiable persons or to the common good (America's War, p. xiii). Yet Strossen proceeds to object to sexual zoning laws (p. xv), overlooking that Mill thought that similar legal restrictions might not unduly infringe the freedom of individuals to pursue their sexual goals: ''[Brothels] may be compelled to conduct their operations with a certain degree of secrecy and mystery, so that nobody knows anything about them but those who seek them; and more than this society ought not to aim at'' (On Liberty, Chapter 5). Don't ask, don't tell. I expected, but perhaps unfairly, more substance from a legal scholar of Strossen's reputation. I say ''perhaps unfairly'' because Klein's book and, a fortiori, Strossen's ''Foreword'' were not meant to be scholarly in a narrow sense. This leads us to the strengths and weaknesses of Klein's America's War on Sex. There is no doubt that he does a great deal of good in his presentation and criticism of the various aspects of the erotophobic campaign against sexuality: the attack on sex education for adolescents; the persistent crusade against innocuous pornography; the continued battle against the rights, acceptance, and safety of sexual minorities; and complaints ad nauseum about the content of college courses on sexuality. (I was, myself, a few years ago, bitten by that prong of erotophobic hostility, having to contend tediously with the accusations of an elderly rightist student who was offended by a joke I told about Aquinas and masturbation. She sought to file charges of ''sexual abuse'' against me with two local sheriffs, and naturally registered dismay with the appropriate university officials.) Klein's careful work torpedoing the erotophobic war against sex had to be done, and he did it well, if only in the name of intellectual integrity. Sexual liberals certainly can depend on this concise, clearly written, no-nonsense tract. It is successful as a compendium of polemics, a handbook for activists doing the dirty work in the cultural and political trenches. The downside, if it be one, is that America's War on Sex is not especially scholarly, by which I mean (only) that it will not likely be of interest to graduate students or professors of sexuality who do their thinking at the level of deep or high theory. For them, reading the book will be like browsing through the popular media, which allows them to cull a cute example here and there for their teaching or research projects but will not provoke them to elaborate Foucault, Butler, or Bataille. Missing from Klein's inventory of the erotophobes who criticize American sexual mores and practices are scholars of the first rank, by whom I mean, at least and among others, John Finnis, Roger Scruton, Martha Nussbaum (in some of her moods), and even Karol Wojtyla (the late John Paul II), that is, thinkers who do not resort to gross violations of the Geneva Conventions but deploy more sophisticated ''smart bombs'' against which it is more difficult to defend liberalism. One of Klein's forays into theory, however, did warm my heart: his astute observations about the relationship between sexual practices and (advances in) technology (pp. 104–106). My own thoughts on this fertile topic, ideas inspired by Marx (because I was doing high theory), can be found in my ''The Mainstream Has Always Been Pornographic,'' Bridge, no. 12 (October–November, 2004), pp. 33–36. That admirable, glossy, expensive journal, like Lingua Franca, has bitten the dust, so write to me if you'd like a digital file.


Objective: To identify core barriers and facilitators to addressing perinatal depression and review clinical, programmatic, and system level interventions that may optimize perinatal depression treatment. Method: Eighty-four MEDLINE/PubMed searches were conducted using the terms perinatal depression, postpartum depression, antenatal depression, and prenatal depression in association with 21 other terms. Of 7768 papers yielded in the search, we identified 49 papers on barriers and facilitators, and 17 papers on interventions in obstetric settings aimed to engage women and/or providers in treatment. Results: Barriers include stigma, lack of obstetric provider training, lack of resources and limited access to mental health treatment. Facilitators include validating and empowering women during interactions with health care providers, obstetric provider and staff training, standardized screening and referral processes, and improved mental health resources. Conclusion: Specific clinical, program, and system level changes are recommended to help change the culture of obstetric care settings to optimize depression treatment.

Clinical judgment is an essential skill required for nurses to provide safe, quality patient care. Nurse educators must develop effective teaching strategies to assist prelicensure nursing students in developing clinical judgment skills. The objective of this study was to determine if a teaching strategy focused on the affective domain of learning and emotional intelligence could be an effective strategy to promote the development of clinical judgment. A guest speaker was invited to the classroom and provided her "lived experience" with multiple sclerosis, which provided a storytelling method of learning. An interpretive descriptive qualitative study was conducted with twenty-one prelicensure diploma registered nursing students enrolled in a medical-surgical nursing course (in the United States of America). Tanner's Clinical Judgment Model (noticing, interpreting, responding, and reflecting) was used as the theoretical framework to guide data analysis. Four themes emerged from the data: 1) attentive listening (noticing), 2) understanding the patient's experience (interpreting), 3) compassionate and empathetic care (responding), and 4) treat the patient as a person, not as a disease (reflecting). Results indicated that storytelling via "lived experiences" is an effective teaching strategy which promotes learning through the affective domain and emotional intelligence while also assisting students in developing clinical judgment. Clinical judgment skills are essential for the graduate nurse transitioning to practice.


insect. If, too, an attempt has been made to find in the cc whites " or c' blues " the scales described in all works on the Microscope, as found on certain members of each group, he has undoubtedly met with disappointment, especially if he has looked where our standard works tell us they are to be found. Thus, in the case of the azure blue (Polyommatus argiolus), we meet with instructions tending to mislead; thus in the Micrographic Dictionary,' under cc Polyommatus," p. 564, we read--"The scales upon the under surface of the wings of P. argiolus and P. argus have been pro osed as test objects. They are of two kinds-one resem \ ling in structurc the ordinary scales of insects, the other of a battledorc form." Again, under the head of '' Pontia," p. 871 :-I' 'i'hc form and structurc of certain scales existing upon the under sidc of the male is curious." Now, any inquircr looking, in either case, in the situations named, mill undoubtedly not find them, for the simple reason that these particular scales are never found on the under side. It was in endeavouring to work out, in 1864, these and a kindred scale that I hit upon certain facts, which perhaps may have been discovered before ; but as I have not been able tofind any record of them, I thought the subject sufficiently interesting to bring before the microscopic world. One fact has reference to the position of the battledore scales ; the other tends to the belief that they, and certain other forms to be described, are, in the three families of the Polyommatus, Pontia (or Pieris), and Hipparchia, characteristic marks of sex-at least I have proved such to be the case, as far as I have been able to obtain specimens for observation. In the '' blues '' proper there is a marked dissimilarity in the colour of the sexea ; for, while the males are of various shades of blue, answering to the names azure, mazarine, &c., the frmales are of a brownish hue, spotted or dashed with bluish scales. Any person seeing them together for the fist time and turned his attention to the scales of insects (especi a% y


Up to now, the machine learning and deep learning algorithms discussed are usually designed to work alone. In the actual industrial operating environment, the working conditions are complex and changeable, so the model once trained in the source domain is used in the target domain, the diagnostic accuracy cannot be guaranteed, and it takes a lot of time to train the model. In view of the above two problems, this paper proposes a bearing fault diagnosis method based on the Transfer Learning Convolutional Neural Network (CRNN). Experimental results show that compared with other existing methods, the CRNN model proposed in this paper reduces the training time of the model while ensuring high accuracy, and the generalization ability of the model is improved, which has a good application value.

Given that landfills are depletable and replaceable resources, the right approach, when dealing with landfill management, is that of designing an optimal sequence of landfills rather than every single landfill separately. In this paper we use Optimal Control models, with mixed elements of both continuous and discrete time problems, to determine an optimal sequence of landfills, as regarding their capacity and lifetime. The resulting optimization problems involve dividing a time horizon of planning into subintervals the length of wmch has to be decided. In each of the subintervals sorne costs, the amount of which depends on the value of the decision variables, have to be borne. The obtruned results are useful for other economic problems such as private an public investrnents, consumption decisions on durable goods, etc. 1 paco firstname.lastname@example.com 2 firstname.lastname@example.com We thank Francisco Alvarez and the participants in the Seventh Vienesse Workshop on Optimal Control, Dynamic Games and Nonlinear Dynamics (held at Vienna 14-16 may, 2000) for their commcnts and J.B.

Aiming at the difficult problem of starting up for sensorless brushless DC motor based on back-EMF zero crossing,a simple startup method was proposed.The proposed method checeel the position of the rotor during the time of acceleration by measuring the zero crossing point of linear voltage differences,to take this zero crossing point as the commutation time of the acceleration period,the torque let the motor to automatically accelerate to the speed which coulel be take over by back-EMF zero crossing,and realized the control of closed loop under acceleration period.The experimental results showed the method can ensure reliable startup of no out-of-step under no load and full load for sensorless brushless DC motor.


Water harvesting techniques (WHTs) are important climate change adaptation measures to better manage rainwater for domestic and agricultural purposes, but which WHT to plan where is subject to sustainability considerations. Moreover, suitability of different WHTs varies from one location to another, depending on physical and socio-economic conditions. This study aimed to identify suitable sites for WHTs taking into account stakeholders' sustainability criteria. In a participatory assessment framework, Geographic Information Systems and the "Simple Multi-Attribute Rating Technique" were combined to generate suitability maps and to guide sustainable WHTs investments. Steps included the calculation of a sustainability index for a set of traditional and newly introduced WHTs from the perspective of two stakeholder groups, farmers and decision-makers, and its integration with layers of biophysical constraints. An application of the framework in the Oum Zessar watershed, southeast Tunisia, shows that traditional techniques are the most suitable and sustainable for farmers and fall within the highly suitable class in 76.4% of the total area, while decision-makers prefer innovative techniques that are highly suitable in 80.4% of the watershed. The framework offers a scalable transparent process for knowledge integration in support of WHT investment decisions that can be adapted to other dryland areas.


A series of β-alkyl-α,β-unsaturated trifluoromethyl ketones have been prepared from the corresponding α-acetylenic trifluoromethyl ketones. The addition of sulfur nucleophiles was shown by chemical and 19 F NMR studies to proceed exclusively by 1,4-addition with no indication of any 1,2-addition products. The unsaturated trifluoromethyl ketones have been shown to be effective inhibitors of rat cytosolic glutathione-S-transferase

Abstract Using role congruity theory as a guiding framework, this study analyzed a set of roles and tasks for senior woman administrators (SWA) at all levels of the National Collegiate Athletic Association (NCAA). An analysis of the responses of 574 SWAs and 542 athletic directors (AD) indicated a general agreement that the SWA performs roles and tasks defined by the NCAA primarily on behalf of gender-neutral programs (i.e., both men's and women's) as opposed to gender-focused programs (i.e., women only). Further, this study supported previous research suggesting that the SWA performs communal roles (i.e., serving as a role model) to a much greater extent than agentic roles (i.e., budget management). There is also evidence that Division I SWAs are performing agentic roles to a much greater extent than Division II and Division III SWAs, and that they are more apt to have an accompanying title as an athletics administrator (93%) as compared to SWAs in the lower divisions (DII = 44% and DIII = 53%). This study found clear perceptual differences between the AD and SWA (p < .05) regarding the extent to which SWAs performed roles related to core management team participation—a finding which raises the question as to whether the SWA truly has a meaningful role in the athletics department. Implications and recommendations for theory and practice are advanced.


The WHO European Childhood Obesity Surveillance Initiative (or COSI), reports that in the fourth round of data collection (2015 - 2017) one in three children aged from six to nine years is living with overweight or obesity [1]. Today it is broadly accepted that overweight and obesity are largely preventable if better healthcare strategies are adopted and innovative interventions are introduced [1], [2]. A promising technology that can help children and their immediate environment adopt WHO-recommended measures and provide nutritional counselling are Voice-based Conversational Agent (VCA). In this work, the service design thinking paradigm [3] is applied to design and develop a new VCA-based service. The main findings of the process are presented along with the key observation that drove the development of the proposed service.


This paper provides an analysis of the population clustering in a novel Success-History based Adaptive Differential Evolution algorithm with Distance based adaptation (Db_SHADE) in order to analyze the exploration and exploitation abilities of the algorithm. The comparison with the original SHADE algorithm is performed on the CEC2015 benchmark set in two dimensional settings (10D and 30D). The clustering analysis helps to answer the question about prolonged exploration phase of the Db_SHADE algorithm. Possible future research directions are drawn in the discussion and conclusion.


In an essay rating study multiple ratings may be obtained by having different raters judge essays or by having the same rater(s) repeat the judging of essays. An important question in the analysis of essay ratings is whether multiple ratings, however obtained, may be assumed to represent the same true scores. When different raters judge the same essays only once, it is impossible to answer this question. In this study 16 raters judged 105 essays on two occasions; hence, it was possible to test assumptions about true scores within the framework of linear structural equation models. It emerged that the ratings of a given rater on the two occasions represented the same true scores. However, the ratings of different raters did not represent the same true scores. The estimated intercorrelations of the true scores of different raters ranged from .415 to .910. Parameters of the best fitting model were used to compute coefficients of reliability, validity, and invalidity. The implications of these coefficients are discussed.


The character of CME is crucial in forecasting geomagnetic storms. In this work, the flux and spectrum of interplanetary energetic protons, together with the particularity of their evolution, were investigated to get the judgment of the acceleration process occurring in CME and evaluate the effect of the CME on the geomagnetic field. The proton flux data from ACE/EPAM during 1998 to 2010 was employed and a so-called spectrum index was derived by modeling the data. Through the statistic work on the proton flux, spectrum and relative CME and geomagnetic disturbance, following conclusions were drawn: (1) The background of spectrum index was –2.6 while its fluctuation reached ±0.4 in the high period of solar activity and it was stable in the low period of solar activity with a value of –3.0; (2) The elevating of the spectrum usually corresponded to the acceleration process in CME, and the scale of 20% or more increasing in spectrum index means a big probability of geomagnetic storms; (3) The energetic proton flux would grow when the shock by high speed stream from coronal hole reached the earth but the spectrum declined slightly; (4) The efficiency of the application of spectrum to geomagnetic storm forecast was evaluated with the relevant data in 2004 and the result shows that the CME originated geomagnetic storm always followed the significant increasing spectrum index, and the proton spectrum index can be used as an indicator of geomagnetic storms.


has been preoccupied with 'accredited' programmes and a risk dominated approach with a focus upon working on the perceived deficits of the young person. This has occurred within a heavily laden case management bureaucracy that has 'endangered' practitioner time for effective relationship building with young people and their freedom to utilise their knowledge and skills in facilitating the change process and working with their strengths. There is much to benefit the practitioner – sift through the information (however it's organised) – and read what is of interest and useful to you. The chapters themselves hold a present currency in youth justice work and these are the key themes. Whilst at times I might have preferred more cross-referencing of material and discussion the book provides a clear pathway for moving forward for practitioners. Young peoples' narratives and strengths are important, their experiences in their early years vital, their family backgrounds essential and active engagement with them and their families crucial if we are to impact upon a young person's offending behaviour.


Spatial diversity at both the transmitter and receiver has been widely regarded as a key technique with which OFDM can be combined to improve further the system performance of wireless networks. Selection diversity is the simplest way to realize spatial diversity, but the performance improvement of this form of diversity is limited. Adaptive antenna arrays can provide significant increases in a system's capacity and performance, but they are characterized by a relatively higher implementation complexity than selection diversity. We combine the benefits of these two spatial diversity methods and propose an adaptive interleaved beamforming approach for broadband MIMO/OFDM systems. By applying eigenvalue decomposition on the set of all available channel correlation matrices, the best beamforming which corresponds to the largest eigenvalue in the set is adaptively selected for each sub-carrier. By doing so, beamforming is adaptively interleaved in the spatial domain. Simulation results show that the proposed system can result in significant performance improvements over conventional adaptive antenna array based OFDM systems in wireless channels. Numerical results also show that the performance of the proposed system can be further greatly improved by employing interleaved-beamforming-dependent power allocation among the sub-carriers.


The hearing sensations stimulated by an audiofrequency current passed through various types of electrodes attached to different portions of the human head or body have been previously investigated and termed electrophonic hearing. More recently, modulated electromagnetic waves have been described to produce hearing sensations. The experiments reported in this paper investigated hearing phenomena in electrostatic fields when the whole head or parts of its surface are exposed to alternating electrostatic fields of audiofrequency. Threshold data obtained by this method are compared to the data reported by others for the different types of electrophonic stimulation mentioned above. Calculations show that all these types of auditory stimulation on the head surface of normal subjects can be explained quantitatively by mechanical tissue excitation by electrostatic forces. Application of this stimulation method for studying vibrotactile sensations on finger tips and other body areas, as well as research applicati...


Sheet resistance has become an industry standard for monitoring high and medium dose ion implants. For low dose there are two sheet resistance techniques available, the direct implant technique and the double implant technique. Careful processing has extended the range of direct sheet resistance measurements down to doses of 2E11 ions/cm2. The double implant technique requires an initial implant to create an easily measured sheet resistance layer that serves as the test vehicle for the second implant. The dose of the second implant is measured by monitoring the change in the sheet resistance due to the implant damage created by the second implant into the first. This double implant technique is not limited to low dose nor to species that are electrically active in the substrate.


In recent years, the giant squid processing industry in Peru exhibited a 59% increase in exports with respect to 2018. According to estimates, this industry generates approximately 30,900 jobs per year. However, some SMEs experience low productivity, such as the PECEPE company, due to plant downtime. This represents 26% of the available time, which translates into the loss of 1760 tons every year. The most constraining external factor the sector faces is uncertainty in resource availability caused by changing weather conditions and informal fishing activities. Although there is a large number of research studies on the fishing industry and resource extraction, literature on processing plant operations is scarce. Within this context, this study seeks to promote a high impact sector in Peru, as well as fostering processing plant competitiveness and productivity. Hence, to address these issues, the authors propose a maintenance management model under the TPM approach. As part of the results from model implementation, a 39% decrease was reported in plant downtime, while maintenance costs also decreased by 16%, which, in turn, increased machine availability and production by 784 tons per year.


Background This project will use two models of Alzheimer's disease (AD) to investigate the therapeutic effects of analogues of cannabidiol (CBD). CBD is a naturally occurring phyto cannabinoid whith is the non psycho active component of cannabis. It is non toxic and is formulated with THC in "Sativex" for the treatment of multiple sclerosis. It has also recently been shown to be beneficial in the form of "Epidiolex" form GW pharmaceuticals in a phase three clinical trial to treat juvenile epilepsy (Dravet syndrome). In the laboratory, we have shown that CBD can reverse the acute effects of application of the neurotoxic peptide beta amyloid peptide (AB-1-42) (Hughes and Herron 2013) which is found in high concentration in post mortem AD brains. In addition, we have shown recently that in the APPswe/PS1dE9 mouse model of Alzheimer's disease that hippocampal slices from these mice have a deficit in long term potentiation at 8 months. (Metais et al., J Alzheimers Dis.;39:315-29). This is likely due to increased levels of Abeta 1-42 and alterations in biochemical signaling associated with increased levels of this protein. Chronic treatment of APPswe/PS1dE9 mice for 28 days with CBD via I/P injection between months 7-8 can reverse the deficit in LTP in these animals. (Hughes 2016) This demonstrates that the reduction in synaptic plasticity associated with models of AD can be reversed by CBD. LTP is used as a cellular model of learning and memory and agents that are known to cause a reduction in LTP reduce cognition.


There are currently no imaging or blood diagnostic biomarkers that can differentiate amyotrophic lateral sclerosis (ALS) from primary lateral sclerosis (PLS) patients early in their disease courses. Our objective is to examine whether patients with PLS can be differentiated from ALS reliably by using plasma lipidome profile and supervised machine learning.


The author attempts to identify causes of the current conflict in Yugoslavia that relate to the regions historical and demographic history. "I concentrate on migration and perceived ethnicity in the Balkans and the crystallization of political blocks based on ethnic identification. I go on to speculate more widely about the importance of political and symbolic processes to demography." (EXCERPT)


The concept of reincarnation is believed to be the rebirth of humans in the world as a form of part of their life journey in accordance with their actions during life with various forms of reincarnation—including being able to be reborn as humans or animals. This article aims to discuss Mullā Ṣadrā's eschatological thoughts, especially his criticism of the concept of reincarnation which has been believed by Hindus and Buddhists. Reincarnation is a topic of discussion for philosophers including Islamic philosophers in discussing the spirit, soul, body, death, and resurrection. Ṣadrā's rejection of the concept of reincarnation is found in one of his main works entitled al-Asfār al-Arba'ah. By using analytical and descriptive methods, it was concluded that Mullā Ṣadrā rejected the concept of reincarnation with his five philosophical arguments, including the natural unity argument, the material and form needs argument, Kawn and Fasād's argument, the vacuum argument, and the argument with five premises. These philosophical arguments are based on Ṣadrā's main philosophical principle, namely the substantial movement of the soul. Even though he rejects the concept of reincarnation, Ṣadrā still believes in the resurrection of the soul and body after death, which will continue the journey towards the highest perfection in the afterlife.


Abstract Conventional dense titanium (Ti) implants cause stress shielding, aseptic loosening and implant failure. This study investigates the effects of porous dental implants (63% porous and 77% porous) with different neck angles (straight, 10° and 15°) on the healthy and osteoporotic bone under different loading conditions (axial load and buccolingual load). Simulation results showed that in cortical bone, the von Mises stresses are greater in the case of 77% porous Ti implant A (straight) as compared to implant B and C (10°, 15° angled neck). Overall, in the case of the osteoporotic bone, the strains are higher than the healthy bone.


The miniaturization trend of microelectric products gives birth to 3D stacking of chips,which is realized by using TSV(through silicon via) technique.A novel micro-tensile specimen of the uniaxial micro-tensile test for measuring the mechanical properties of Cu-TSV is proposed.Finite-Element Method(FEM) has been used to optimize the design of the supporting frame of the sample with a Cu-TSV thin film,which can effectively reduce the damage ratio of the sample during operations.The surface-treated Ti seed layer has substituted for the traditional Cr/Cu seed layer to reduce the stress concentration and prevent the specimen from alkali corrosion when etching the seed layer.The samples have been tested by the uniaxial micro-tensile system to obtain the mechanical properties of the Cu-TSV thin film.The measured Young's modulus and the ultimate tensile strength of Cu-TSV is 25.4—32.9 GPa and 574—764 MPa,respectively.


Abstract: In this programmatical article on intellectual history, I propose to study how the political community was conceived in 16th century New Spain, particularly in two of its forms: the city and the realm. The work program consists of an assessment of the historiography on the subject, a methodological strategy that recovers some assumptions from the so-called history of political languages and a description of the sources that could be used for research.

The difficult-to-machine property of titanium alloy has been on important subject in the field of manufacture, especially for the thin-walled structure. The material removal amount can reach 95% and even 98%. This paper applies the finite element method (FEM) to evaluate the process of machining. The influences of the different tool paths in rough machining frame structure is studied. The influence of the tool path on the dynamic characteristic in finish machining thin-walled frame structure is also investigated. As a result, the tool path in rough machining will influence the machining efficiency and tool life and influence the dynamic characteristics of thin-walled components in finish machining.


We studied the carrier dynamics in colloidal octapod-shaped cadmium selenide/cadmium sulfide (CdSe/CdS) nanocrystals in the solution phase via pump–probe optical techniques with subpicosecond resolution. We could resolve bleaching from two different types of electronic states having distinct dynamics and assigned them to states delocalized in the pods and mildly localized in the core based on the good agreement of energies found with effective mass modeling. Contrary to other CdSe/CdS core/shell nanocrystals, such a mild localization has geometrical origins as the best agreement was found for negligible conduction band offset. Moreover, even though the large surface of the CdSe/CdS heterointerface results into a weak signature of electron trapping in the bleaching spectrum, we found that a relevant fraction of electrons do remain delocalized in pod states for long times and are thus available for diffusion in photovoltaic applications where the highly branched geometry is expected to advantageously yield ...


Little is known about the costs of crime to victims. We use unique and detailed register data on victimizations and monthly labor market outcomes from the Netherlands and estimate event study designs to assess short- and long-term effects of criminal victimization. Across offenses, both males and females experience significant decreases in earnings (up to −12.9%) and increases in benefit receipt (up to +6%) after victimization. The negative labor market responses are lasting (up to 4 years) and accompanied by shorter-lived responses in health expenditure. Heterogeneity results suggest that most groups of victims, including the noninjured, suffer nontrivial losses.


more synthetic, narrative approach to the material. In this respect, however, the volume simply reflects the state of research of the discipline as a whole: the field of Byzantine law is still very much oriented towards the unraveling of the basic history of sources. Ultimately none of these issues detract from what is an excellent and sorely needed English-language reference source for eastern church law. It will be of great use to both researchers and students. Hopefully it will stimulate and facilitate further interest in what remains a very neglected field of study.
