Allozymatic activity in samples prepared for morphometric and molecular analyses in two species of the Drosophila guarani group ( Diptera : Drosophilidae )

The degree of genetic variation within populations is important and has received some attention in the literature as it can be an indication of the overall species vitality and of its population ́s potential to adapt to new environments. Such variation has been assessed through several morphological and molecular markers, which in combination give better results about the evolutionary history and population genetic structure of a species. The aim of this work was to evaluate the allozymic activity in specimens of two species of the Drosophila guarani group, D. ornatifrons and D. maculifrons, using a sample separation methodology that maximizes obtaining morphological and molecular data. Our results showed that there is a higher activity of the allozymic loci analyzed in the thorax and abdomen, and also that the wing and aedeagus previous separation for morphometric analyses did not change the allozyme loci visualization in the gel. No loci analyzed presented specific pattern of expression in the head, indicating that this body part could be used to perform DNA extraction for further molecular markers analyses. Thus, the same specimen can be Dros. Inf. Serv. 93 (2010) Research Notes 183 analyzed for different markers, increasing the power of investigation of the evolutionary history and genetic population structure of the species of interest. Moreover, this methodology diminishes the need to collect many individuals and/or to perform several collection trips to the same area, therefore, maximizing the sample utilization obtaining results for several different markers (morphological and molecular) from the same sample.
Long Term Funding and Regulation: Facilitating Financial Stability and Development (Low Income Developing Countries)

Basic and fundamental issues which link financing and funding activities to financial regulation involve the problems of systemic risks and asymmetric information. In addition to addressing these issues, this paper will also consider other issues related to long term funding, which affect financial stability and development in Low Income Developing Countries (LIDCs) - namely inadequate regulatory frameworks, as well as constraints and accessibility to long term funding. By considering the recent developments with the Basel framework, it will seek to illustrate, by way of reference to studies, why low income developing countries, as well as selected emerging economies are still lagging behind in terms of the implementation of regulatory standards. It will also aim to demonstrate how these countries would largely benefit from effective implementation of these standards. Whilst aiming to facilitate means whereby sources of longer term funding could be enhanced, it will also consider the disadvantages and risks associated with longer term funding, challenges imposed by debt sustainability and propose alternative sources of funding. Transparency and disclosure, it will be highlighted, continue to generate severe obstacles to financial development and growth, as will be reflected from results of certain investigations.
Singular value decomposition based feature classification for single trial brain-computer interface design

The performance of any brain-computer interface (BCI) highly depends on being artifact free. In this study, we propose a mathematical modelling approach to design an efficient non-invasive BCI based on P300 component found in single trial visual evoked potential (VEP) signals. Since the brain processes multiple functions simultaneously the extracted VEP results are in a complex pattern. Further, the characteristics of the P300 component are difficult to be determined a priori especially when the signals are analysed on single trial basis. However, the data used by BCI systems have high dimensionality due to the recording from multiple electrode locations and this high dimensionality could be exploited for reducing the effects from artifacts, using specific pre-processing techniques. In this research study, we propose a mathematical framework for noise reduction and a two-step classification using dynamic methods that results in an enhanced BCI design. The application of singular value decomposition (SVD) to the discrete single trial VEP data facilitates reduction of noise and operational data dimension. Frequency specific filtering further reduces noise and a computationally simple distance based measure with novel method of using two thresholds was utilised for classification. The experimental results give a very low false accept rate (FAR) and false reject rate (FRR) and a near negligible equal error rate (EER) of 2.91%. The high accuracy obtained validates our proposed single trial based approach.
Hepatitis B Surface Antigen Should Not Be the Only Sought Marker to Distinguish Blood Donors towards Hepatitis B Virus Infection in High Prevalence Area

Since its discovery by Blumberg in 1965, the hepatitis B surface antigen (HBsAg) is used as the fingerprint of hepatitis B infection. Occult hepatitis B infection (OBI) is defined by a viral replication (DNA detectable) in the absence of HBsAg. Burkina Faso is a high endemic area where the prevalence is higher than 14%. At the National Center for Blood Transfusion (NCBT) of Ouagadougou, HBsAg is the only sought marker used to distinguish donors towards Hepatitis B Virus (HBV). Acceptation of blood donation is based specifically on the absence of HBsAg, which exposes to the risk of HBV transmission during transfusion. The goal of this study is to evaluate this risk by determining the prevalence of OBI in blood donors. Patients and Methods: It was a five-month prospective study on blood donations collected from January to May 2016. The HBc antibody has been sought in the serums of negative HBsAg donors. The measure of B DNA by Real Time PCR (polymerase chain reaction) and that of antibodies anti-HBs have been proposed to anti-HBc positive donors. Abdominal ultrasound, the transaminases, prothrombin level, alphafeto-proteins, hepatic fibrosis have been proposed to donors who were detectable for the DNA. Sociodemographic parameters have been collected. The test costs were borne by donors who were recalled by phone to adhere to the study. Results: Among 1980 negative donors HBsAg, 872 (44%) were positive for anti-HBc. 160 on 872 donors were received for consultation, among which 76 (76/160) were able to realise DNA which was detectable in 25 donors on 76, thus a prevalence of 32.8%. The mean value of DNA was 953 IU/ml. Physical examination and hepatic ultrasounds were normal except a case where hepatic steatosis was found. The biologic standard hepatic results were in normal range. None of the patient was able to realise hepatic fibrosis evaluation. A case of co-infection HIV/OBI was noted. Conclusion: This study shows that in Burkina, almost half of blood bags transfused are anti-HBc positive and around one third (32.8%) probably have HBV DNA. This poses a potential risk of contamination for non-immunized recipient. It is thus important that, in addition to HBsAg, Anti-HBc should be systematically sought in order to minimize the risk.
Career Guidance in Secondary Schools - A literature Review and Strategic Solutions for Vietnamese Rural Areas

This paper reviews the role of career guidance and counseling at schools across the globe. The aim of this paper is to overview the career guidance in schools through literature review in order to have perspective of this field, and it further tries to find orientation solutions to rural Vietnamese contexts. Developing social economic in rural areas by moving from agricultural field to industrial aspects, the suitable solution by enhancing quality of education in career value based on students interests, abilities and passion, with more students to switch over to vocational education for their future career opportunities. It will not only decrease the number of undergraduate’s unemployment rate, as indicated by the statement, “excess of higher education degrees but lack of skilled workers” but also provide enough skilled workers for several projects ventured by foreign companies in rural Vietnam. This paper explores the existing literature and analyzes various works done on the importance of establishing career guidance at schools and finds that Vietnam is still deprived of the true spirit of career guidance and lack of vigorous research. While comparing the context of Vietnam with other countries, it may be inferred that career guidance has not yet been paid proper and adequate attention; hence career guidance has not yielded the desired objectives. The current study recommends that willing and motivated staff should be recruited and be given professional training and special courses so that the desired goals and objectives may be achieved. Because the key differences between guidance systems in different countries are related to experiences of economic development, to political system, to social and cultural factors, to education and training system, and to professional and organizational structures.
Quantum error correction for continuously detected errors

We show that quantum feedback control can be used as a quantum error correction process for errors induced by weak continuous measurement. In particular, when the error model is restricted to one, perfectly measured, error channel per physical qubit, quantum feedback can act to perfectly protect a stabilizer codespace. Using the stabilizer formalism we derive an explicit scheme, involving feedback and an additional constant Hamiltonian, to protect art (n-1)-qubit logical state encoded in n physical qubits. This works for both Poisson (jump) and white-noise (diffusion) measurement processes. As an example, we show that detected-spontaneous emission error correction with a driving Hamiltonian can greatly reduce the amount of redundancy required to protect a state from that which has been previously postulated.
Template assisted fabrication of free-standing MnO2 nanotube and nanowire arrays and their application in supercapacitors

In this Letter, an innovative technique is reported to control the fabrication of free-standing MnO2 nanotube and nanowire arrays. The synthesis is based on a three-step process, using porous anodic aluminum oxide as a template, and enables the selective fabrication of vertically aligned MnO2 nanotubes or nanowires on large areas. The as-prepared MnO2 nanotube and nanowire arrays are investigated as electrode materials for supercapacitor applications and show a good electrochemical performance with specific capacitances of 210 F g−1 at 1.9 A g−1 and 231 F g−1 at 0.5 A g−1, respectively. The investigation of the rate capability of both structures indicates a superior performance of the nanotube arrays.
19 CLINICAL APPROACHES TO WORKING WITH LATINO ADULTS

there exist several compelling reasons to identify and disseminate effective clinical approaches to working with Latinos. In particular, the Latino population in the United States has grown tremendously over the past 10 years, and census data predict that by 2050 the number of Latinos will exceed 125 million and represent more than one fourth of the U.S. population (Passel & Cohn, 2008). In addition, a large body of literature has documented pervasive health-care disparities affecting Latinos (U.S. Department of Health and Human Services [USDHHS], 2001), suggesting that existing clinical interventions may inadequately address the needs of Latinos. However, despite the increased attention to the development and provision of culturally appropriate clinical services for Latinos, there remain significant disparities in themental health care received by Latinos (Blanco et al., 2007; Vega et al., 2007). We suggest that one explanation for these continuing health-care disparities may be found in the difficulty the mental health field has had in conceptualizing how best to integrate cultural considerations into clinical work (Cardemil, 2008). In particular, while there exist many different perspectives in the literature on what constitutes acceptable integration of culture into psychotherapy (e.g., Atkinson, Bui, & Mori, 2001; Bernal & Sáez-Santiago, 2006; Hall, 2001; La Roche, 2002; Whaley & Davis, 2007), there is no overarching framework into which to organize these different perspectives. For example, the American Psychological Association has published a set of guidelines for clinicians who work with individuals from ethnic, linguistic, and culturally diverse backgrounds (American Psychological Association [APA], 1993). These guidelines focus exclusively on therapist attitudes toward issues of diversity, knowledge about particular ethnic and cultural groups, and behaviors when working with individuals from different backgrounds. No mention is made, however, about the ways in which particular interventions may or may not need to be adapted for work with particular groups of individuals. As a result, many interested clinicians and scholars may remain unsure about how to proceed with efforts to consider cultural issues in their treatment approaches with Latinos. In this chapter, we concretize a framework proposed by Cardemil (2008) in which different perspectives on how to incorporate conceptions of culture are organized according to a variety of assumptions regarding the active therapeutic ingredients and their relation to culture. We
Topic Patterns in an Academic Literary Journal: The Case Of "Teksty Drugie"

The availability of digitised full-text resources, as well as bibliographical data in standard database format, has recently opened a new chapter in the sociology of literature by revaluating empirical approaches and data-driven scholarship. The road to this “empirical turn” in literary scholarship has been paved by such scholars as Franco Moretti (2005, 2013) and Matthew Jockers (2013), who showed how empirical data like bibliographical records, annotations, title words, genre categorization, etc., may help in generating new knowledge about literary periods. This approach gathered its momentum as other works exploring the possibility of using such data to answer particular research questions emerged. Due to the shortage of space we will name just a few that have the most influence on this paper, dividing them into three research strands. Firstly, the use of bibliographical data for statistical inferences on literary processes, e.g Bode’s (2012) rereading of Australian literary history through the data from AustLit (Australian Literary Bibliography). Secondly, the study of author co-occurrences and mutual references, e.g. visualising literary circles on the basis of such data by Long and So (2013a, 2013b). Thirdly, the application of topic modelling to uncover pertinent issues in literary scholarship, e.g. Goldstone and Underwood’s analyses of the evolution of American literary scholarship on the example of PMLA (2012) and seven major literary journals (2014). In combining those approaches into a macroanalytical study of Teksty Drugie, we also adopted the rationale introduced by the 40th anniversary internet edition of Signs, a literary journal dedicated to feminist criticism.
IpaB–IpgC interaction defines binding motif for type III secretion translocator

The delivery of virulence factors into host cells through type III secretion systems is essential for enterobacterial pathogenesis. Molecular chaperones bind specifically to virulence factors in the bacterial cytosol before secretion. Invasion plasmid gene C (IpgC) is a chaperone that binds 2 essential virulence factors of Shigella: invasion plasmid antigens (Ipa) B and C. Here, we report the crystal structure of IpgC alone and in complex with the chaperone binding domain (CBD) of IpaB. The chaperone captures the CBD in an extended conformation that is stabilized by conserved residues lining the cleft. Analysis of the cocrystal structure reveals a sequence motif that is functional in the IpaB translocator class from different bacteria as determined by isothermal titration calorimetry. Our results show how translocators are chaperoned and may allow the design of inhibitors of enterobacterial diseases.
Outbreak of Swine-Origin Influenza A (H1N1); Experience of a Regional Center in Seoul during a Month, August-September 2009

Background: The aim of this study is to clarify the epidemiology of swine-origin influenza A (H1N1) virus 2009 (S-OIV) during the first month of outbreak at one of influenza clinic in Seoul, Korea. Methods: We documented the epidemiologic and clinical features of S-OIV-confirmed cases who visited a university hospital in Northeastern Seoul between August 21 and September 20, 2009. Nasopharyngeal swab of patients with acute febrile respiratory illnesses were evaluated with rapid influenza antigen tests and multiplex RT-PCR for S-OIV and seasonal influenza A. Results: A total of 5,322 patients with acute febrile respiratory illnesses were identified at our influenza clinic for the study period. S-OIV was confirmed in 309 patients by RT-PCR. The patients ranged from 2 months to 61 years of age and 189 patients (61.2%) were teenagers. Eighty-one patients had known contact with S-OIV-confirmed patients in schools (N=61), households (N=15), and healthcare facilities (N=3). Frequent symptoms were fever (94.5%), cough (73.1%), sore throat (52.1%), and rhinorrhea (50.5%). Gastrointestinal symptoms were also present in 10 patients (4.9%). Ten patients (4.9%) required hospitalizations. Seventy patients (22.7%) could not take oseltamivir at the first visits, however, all of them recovered without complication. Rapid antigen tests showed the sensitivity of 44.4% (130/294). Patients with positive antigen tests, compared with negative antigen tests, showed higher frequencies of rhinorrhea (60.8% vs 43.3%, P=0.004) and stuffy nose (33.8% vs 20.1%, P=0.012). Conclusion: S-OIV infections spread predominately in school-aged children during the early accelerating phase of the outbreak. Rapid influenza antigen tests were correlated with nasal discharge and obstruction. (Korean J Clin Microbiol 2010;13:103-108)
Modeling Compositions of Impedance-based Primitives via Dynamical Systems.

In this work, we introduce a novel Dynamical System (DS)-based approach for modeling complex and compliant manipulation tasks, that are composed of a sequence of action phases with different compliance requirements; i.e. impedance primitives. We adopt a closed-loop (DS)-based control architecture and present the Locally Active Globally Stable (LAGS)-DS formulation. In LAGS-DS we seek to model the whole task as a globally asymptotically stable DS that has locally task-varying dynamics and smoothly transit between them. These locally task-varying dynamics represent the set of impedance primitives, hence, rather than modeling the task as a discretization of impedance primitives, we model it as a composition of impedance primitives in a single DS-based controller. In this paper, we present the theoretical background for this novel DS, briefly describe the learning approach and provide 2D simulations of LAGS-DS learned from toy data.
Deformations de reseaux dans certains groupes resolubles

Abstract. We aim to study local rigidity and deformations for the following class of groups: the semidirect product Γ = Z oA Z where n ≥ 2 is an integer and A is a hyperbolic matrix in SL(n, Z), considered first as a lattice in the solvable Lie group G = R oA R, then as a subgroup of the semisimple Lie group SL(n + 1, R). We will notably show that, although Γ is locally rigid neither in G nor in H, it is locally SL(n + 1, R)–rigid in G in the sense that every small enough deformation of Γ in G is conjugated to Γ by an element of SL(n + 1, R).
Thermoelectric transport and microstructure of optimized Mg 2 Si 0 . 8 Sn 0 . 2 †

Solid solutions of magnesium silicide and magnesium stannide exhibit excellent thermoelectric properties due to favorable electronic band structures and reduced thermal conductivity compared to the binary compounds. We have optimized the composition Mg2Si0.8Sn0. 2 by Sb doping and obtained a thermoelectric figure of merit close to unity. The material comprises of several phases and exhibits intrinsic nanostructuring. Nevertheless, the main features of electronic transport can be understood within the framework of a single parabolic band model. Compared to Mg2Si we observe a comparable power factor, a drastically reduced thermal conductivity and an increased effective mass.
An Amplifying Tunable Transmitarray Element

In this letter, a transmitarray element with electronically tunable and amplifying features is proposed. This transmitarray element consists of stacked patches, an amplifier, and reflection-type phase shifters. The linearly polarized wave is converted into the guided wave by the receiver patch. After modulation of the phase shifters and amplifier in the transmission line, the guided wave is lastly reradiated by the transmitter patch. The proposed design is supported by full-wave electromagnetic simulation and verified through waveguide simulator experiment. The measuring results show that the designed transmitarray element achieves over 400° of phase shift in a broad band from 4.95 to 5.5 GHz. The introduction of the amplifier makes it produce the average gain of 7.7 dB. Furthermore, the proposed transmitarray element has a very small longitudinal size (~ 0.135λ), and it is easy and low-cost to fabricate. Thus, this transmitarray element could be developed for potential applications in several areas where high gain and beam steering are needed.
Scaling Human Activity Recognition via Deep Learning-based Domain Adaptation

We investigate the problem of making human activity recognition (AR) scalable-i.e., allowing AR classifiers trained in one context to be readily adapted to a different contextual domain. This is important because AR technologies can achieve high accuracy if the classifiers are trained for a specific individual or device, but show significant degradation when the same classifier is applied context-e.g., to a different device located at a different on-body position. To allow such adaptation without requiring the onerous step of collecting large volumes of labeled training data in the target domain, we proposed a transductive transfer learning model that is specifically tuned to the properties of convolutional neural networks (CNNs). Our model, called HDCNN, assumes that the relative distribution of weights in the different CNN layers will remain invariant, as long as the set of activities being monitored does not change. Evaluation on real-world data shows that HDCNN is able to achieve high accuracy even without any labeled training data in the target domain, and offers even higher accuracy (significantly outperforming competitive shallow and deep classifiers) when even a modest amount of labeled training data is available.
