Overview of liposarcomas and their genomic landscape

Liposarcoma (LPS) is among the most common soft tissue sarcoma affecting adults. LPS is divided into three biologic subtypes characterized by specific genetic alterations. The most common LPS subtypes, well-differentiated and dedifferentiated LPS, are nearly uniformly characterized by ring chromosomes and giant markers with chromosomal amplification of 12q13-15 and resulting amplification of oncogenes MDM2, CDK4, and HMGA2. Myxoid/round cell LPS commonly exhibits a distinctive (12; 16) translocation resulting in the FUS-DDIT3 fusion gene. Finally, pleomorphic LPS harbors diverse complex genomic changes and chromosomal rearrangements and frequent mutations in TP53, RB1, and NF1 leading to dysregulation of tumor suppressor pathways. In this review, we summarize the currently available knowledge on the genomics and genetics of LPS subtypes as well as recent advances in the multimodality management of LPS.
Do big dads make big babies? Paternal effects on larval performance in red-eyed treefrogs of Belize (Agalychnis callidryas, A. moreletti)

Under the good genes model of sexual selection, females prefer males with attributes that signify high genetic quality to improve offspring fitness. This study tested the hypothesis that female mating preferences result in enhanced offspring performance, owing to genetic variation among sires in two species of red-eyed treefrogs (Agalychnis callidryas and A. moreletii). The study provides evidence for paternal size effects on offspring traits, most notably on hatchling size, larval duration and size at metamorphosis. Large males of both species produced larger hatchlings relative to half-sibs. Larger hatchlings may have immediate growth and survival advantages that propel them through the larval period and suggests the potential for increased post-metamorphic fitness benefits. Large males of A. callidryas sired larger froglets and there were positive correlations between sire size and froglet traits for both species. Tadpoles of both species that remained in a longer larval period emerged from metamorphosis at a greater size. The two species share similar life history traits, but considerable inter-specific differences of paternal effects between A. callidryas and A. moreletii may help to explain the variation in breeding behaviour and tadpole biology within these two species. In this system, females may exercise directional selection for offspring at a larger metamorphic body size that will increase her fitness through enhanced survival and reproductive success.
Challenge in Enhancing the Teaching and Learning of Variable Measurements in Quantitative Research.

Statistical analysis is one component that cannot be avoided in a quantitative research. Initial observations noted that students in higher education institution faced difficulty analysing quantitative data which were attributed to the confusions of various variable measurements. This paper aims to compare the outcomes of two approaches applied in enhancing the quality of teaching and learning statistics. 143 communication undergraduate students were involved as participants in this action research. They were divided into two groups, in which one experienced “group quiz” technique and the other went through the newly designed “challenge the challenger” technique. The effects of interventions given were measured from the students’ cognitions of variable measurements before and after such interventions. The action taken is believed to play an important role in the effort to improve teaching and learning of variable measurements in quantitative research.

Ce lymphome touche principalement le sujet jeune, avec un âge median de 33 ans au diagnostic. Cette hemopathie maligne presente un excellent pronostic avec des taux de guerison variant de 70 [. ]
Silver-Doped Nanoclay with Antibacterial Activity

The aim of this study was to synthesize Ag-nanoclay composite by solid ion exchange, then characterize, and evaluate the antibacterial activity. This newly introduced ion exchange is a simple and low cost technique, which provides a quicker method. Without chemical treatment, nanoclay was subjected to an ion exchange process in media containing molten salt of silver at 300 and 400 °C and at different periods. Scanning electron microscopy showed that the flakes’ structure was opened by higher temperature and longer time. DRS graph revealed that Ag particles were successfully loaded, and that higher temperature and longer time increased the loading amount. Changes in basal reflection in XRD peak validated the presence of Ag. The Release test indicate that the materials do not present any risk for drinking water treatment since the leached metals were very small and in acceptable concentrations. The constant amount of release after four hours of sharp releasing. The antibacterial activity of the prepared composites was tested against gram-negative Escherichia coli and Staphylococcus aureus using the disc diffusion method. Presence of an inhibition zone clearly indicates the antibacterial effect of the composites. The results demonstrate that silver can be introduced onto nanoclay by single-step ion exchange.
The Dependence of a Quantum Acoustoelectric Current on Some Qualities in a Cylindrical Quantum Wire with an Infinite Potential GaAs/GaAsAl

The quantum acoustoelectric (QAE) current is studied by a quantum kinetic equation method and we obtain analytic expression for QAE in a cylindrical quantum wire with an infinite potential (CQWIP) GaAs/GaAsAl. The computational results show that the dependence of the QAE current on the radius of CQWIP GaAs/GaAsAl, the Fermi energy 3⁄4F and temperature T is non-monotonic, and the appearance of peak when the condition 1⁄2~ q 1⁄4 1⁄2~ k þ h ðBn0 ;N0 B2n;N Þ 2mR2 (n 61⁄4 n0 and N 61⁄4 N0) is satisfied. Our result indicates that the dominant mechanism for such a behavior is the electron confinement in the CQWIP GaAs/GaAsAl and transitions between mini-bands. All these results are compared with those for normal bulk semiconductors and superlattice to show the differences. The dependence of a QAE current on some qualities in a CQWIP GaAs/GaAsAl is newly developed. [doi:10.2320/matertrans.MA201514]
Sensitivity of Crop Yield to Extreme Weather in Nigeria

This study analyzed how extreme weather conditions affect the mean and variability of the yields of 11 staple crops in Nigeria. The research involved the use of a pooled panel data of 36 states and the federal capital territory over the period of 1991-2012. The framework for analysis consisted of the production risk model developed by Just and Pope for yield estimation. Unit root tests and Maximum Likelihood Estimation techniques were used to obtain reliable estimates of the model’s parameters. The results showed that the mean and variance of the yield of all the staple crops were diversely influenced by extreme weather events.
Expression of narrow focus in spontaneous Estonian dialogues

Estonian offers several means for expressing narrow focus, including a choice between a syntactic strategy resulting in marked constituent order, and a prosodic strategy resulting in marked nuclear accent placement. The present study examines the usage of the different focus-marking strategies in spontaneous dialogues, with the primary aim of verifying the hypothesis that when either the syntactic or the prosodic strategy must be used, the prosodic strategy is preferred. The results show an overwhelming preference for keeping both the constituent order and the accent placement unmarked. In the relatively small number of cases where either the syntactic or the prosodic strategy must be chosen, a slight preference for the prosodic strategy can be observed. There also exists a minor strategy of focus fronting, whereby both the constituent order and the nuclear accent placement are marked; the role of this strategy requires further study. Kokkuvote.

Intent-Aware Diverse Social Image Retrieval

Behind each photographic act is a rationale that impacts the visual appearance of the resulting photo. Better understanding of this rationale has great potential to support image retrieval systems in serving user needs. However, at present, surprisingly little is known about the connection between what a picture shows (the literally depicted conceptual content) and why that picture was taken (the photographer intent). In the thesis, we investigate photographer intent in a large Flickr data set. First, an expert annotator carries out a large number of iterative intent judgments to create a taxonomy of intent classes. Next, analysis of the distribution of concepts and intent classes reveals patterns of independence both at a global and user level. Finally, we report the results of experiments showing that a deep neural network classifier is capable of learning to differentiate between these intent classes, and that these classes support the diversification of image search results.
Estimation of the Seedling Vigor Index of Sunflowers Treated with Various Heavy Metals

In order to quantitatively describe the relative effect of the concentrations of heavy metals (i.e., Cd, Pb, Zn, and Ni) on the germination and seedling growth of plants, the seed germination tests were conducted using sunflower seeds treated with various heavy metals, and a mathematical model to estimate the seedling vigor index (SVI) is proposed. From the results of germination tests, a decrease in the seed germination percentage with an increase in the heavy metal concentration was observed, and the inhibitions of seedling growth were clearly detectable above certain critical concentrations (e.g., 50 mg-Cd/l, 50 mg-Ni/l, 100 mg-Zn/l, and 1,000 mg-Pb/l). According to both the IC50 and a1 values, the resulting order of phytotoxicity for the heavy metals on sunflower seed germination was Cd>Ni>Zn>Pb. The SVI estimation model developed in this study rigorously explained the relationship between the heavy metal concentration and the SVI values. Thus, SVI values for a certain plants can be, a priori, obtained, with the heavy metal concentrations in the aqueous phase without performing the germination tests. Although the coefficients of SVI estimation model changed from different species of plants, the empirical SVI estimation model derived from theoretical background can be utilized for other species of plants.
Arbitrage-Free Pricing of XVA for American Options in Discrete Time

Total valuation adjustment (XVA) is a new technique which takes multiple material financial factors into consideration when pricing derivatives. This paper explores how funding costs and counterparty credit risk affect pricing the American option based on no-arbitrage analysis. We review previous studies of European option pricing with different funding costs. The conclusions help to compute the no-arbitrage price of the American option in the model with different borrowing and lending rates. Another model with counterparty credit risk is set up, and this pricing approach is referred to as credit valuation adjustment (CVA). A defaultable bond issued by the counterparty is used to hedge the loss from the option’s default. We incorporate these two models to assess the XVA of an American option. The collateral, which protects the option investors from default, is considered in our benchmark model. To illustrate our results, numerical experiments are designed to demonstrate the relationship between XVA and parameters, which include the funding rates, bond’s rate of return, and number of periods.
Applicability of a motor rehabilitation system in stroke victims

Introduction: The recovery of stroke patients is long and boring due to the repetitive nature of the exercises used and the length of treatment. Thus, we started using virtual reality as an alternative and, because of its advantages, health professionals are adapting video games for physical therapy. However, there are some limitations, such as the fact that games are designed for entertainment and not for therapeutic purposes. Objective: In order to mitigate gaps in assistive devices for physical therapy, this study describes the development and applicability of a computer support system for moto rehabilitation - Ikapp - in stroke victims. Methods: Twenty-seven stroke patients filled out a socioeconomic questionnaire, tested Ikapp during five minutes and answered a usability and satisfaction questionnaire about handling the tool. The chi-square test was used to analyze any association between sociodemographic factors and the features of the system. Results: The Ikapp system can be an excellent device to assist neurological rehabilitation of stroke patients, as participants questionnaires showed that 85.2% were satisfied in regard to motivation and inclusion of Ikapp in physiotherapy and 77.8% relative to ease of interaction with the tool. Conclusion: The Ikapp system proved to be an easy-to-use and accessible computer support system for patients with functional limitations.
Atomic data from the IRON Project

This is the third paper in a series giving collision rates for electron excitation of the P 1 2 − P 3 2 ground state fine-structure transition in aluminiumlike ions. In this paper we give data for the transitions in P iii (17.9 μm), S iv (10.5 μm) and Cl v (6.71 μm). For the P and Cl ions the only existing results are nearly 30 years old and were obtained using a method which does not incorporate resonance effects. For S iv, previous close-coupling calculations do exist but we show that our more elaborate calculation changes the rate coefficients by about 50% at lower temperatures.
Environmental and ecological hydroinformatics to support the implementation of the European Water Framework Directive for river basin management

Groundwater remediation operation involves several considerations in terms of environmental, technological and socio-economic aspects. A decision support tool (DST) becomes therefore necessary in order to manage problem complexity and to define effective groundwater remediation interventions. CCR (Credence Clearwater Revival), a decision support tool for groundwater remediation technologies assessment and selection, has been developed to help decision-makers (site owners, investors, local community representatives, environmentalists, regulators, etc.) to assess the available technologies and select the preferred remedial options. The analysis is based on technical, economical, environmental and social criteria. These criteria are ranked by all involved parties to determine their relative importance for a particular groundwater remediation project. The Multi-Criteria Decision Making (MCDM) is the core of the CCR using the PROMETHEE II algorithm.
Software Engineering - Agile Methodology using SCRUM

As agile software development becomes a trend, Lots of organizations are using the agile methodology for better life cycle of product development. To achieve the quality product methods needs to be the more structured definition of what agile methodologies is and what is the better level of its maturity. Traditional development methodologies rely on documents and process defined and used from one analyst to the next. SCRUM has some key challenges to use it. First customer’s goals are set without the knowledge of their requirements and needs. The client’s requirements are not be good enough from the need perspective. Then, given the fact that a client thinks in terms of the minimum organizational set of features in a just-in-time process.
Fabrication of self-standing silver nanoplate arrays by seed-decorated electrochemical route and their structure-induced properties

We present an electrochemical route to synthesize silver nanoplates on seed-decorated Indium tin oxide (ITO) glass substrate. The nanoplates are several tens of to several hundred nanometers in dimension. The density of nanoplates covered on the substrate can be controlled well by adjusting the amounts of seed. All the nanoplates are standing on the substrate uniformly even at very high density. Silver nanoplate arrays displayed an extraordinary superhydrophobicity after chemical modification and can serve as highly active surface-enhanced Raman scattering (SERS) substrates for microdetection. The arrays can also be used as electrodes for electrochemical capacitor with high power density.
Implications of movement patterns for gene flow in black rat snakes (Elaphe obsoleta)

Gene flow is fundamental to evolutionary processes but knowledge about movements of individuals and their offspring necessary for gene flow is scant. We investigated potential ecological components of genetic connectivity within a population of black rat snakes (Elaphe obsoleta) by radio-tracking 82 individuals. Because adult black rat snakes are highly faithful to their hibernaculum, gene flow between hibernaculum populations has to occur through mating between members of different hibernacula or through juvenile dispersal. The present study was the first to assess the spatial dispersion of a complete network of hibernacula. The mean distance between the nearest-neighbour hibernacula was 811 m, which was less than the mean distances that reproductive males and females were found from their hiber- nacula during the mating season. Estimates of maximum distances individuals were from their hibernacula during the mating season indicated that, on average, a female was likely to mate with males that came from two hibernacula away from the female's own hibernaculum. Both males and females appeared to contribute actively to gene flow by moving more and increasing their distance from their hibernacula during the mating season. In addition, on average, females nested closer to a hibernaculum other than the one they attended, thereby potentially increasing the likelihood that their offspring would join hibernacula other than their mothers'. Thus, spatial and movement patterns of male and female black rat snakes are consistent with genetic evidence of extensive out-breeding among local hibernaculum populations. Resume : Le flux des genes est un processus fondamental de l'evolution, mais l'influence des deplacements d'individus et de leur progeniture sur le flux des genes est encore mal connue. Nous avons etudie les composantes ecologiques potentielles de la connectivite genetique au sein d'une population de serpents ratiers ( Elaphe obsoleta) en suivant 82 individus par radiotelemetrie. Parce que les serpents ratiers adultes sont tres fideles a leur hibernacle, le flux des ge- nes entre les populations des divers hibernacles doit se faire par accouplement entre membres d'hibernacles differents ou par dispersion des jeunes. Cette etude est la premiere a evaluer la dispersion spatiale d'un reseau complet d'hibernacles. La distance moyenne entre un hibernacle et l'hibernacle voisin le plus proche a ete estimee a 811 m,
Spectral properties and the Kondo effect of cobalt adatoms on silicene

In terms of the state-of-the-art first principle computational methods combined with the numerical renormalization group technique the spectroscopic properties of Co adatoms deposited on silicene are analyzed. By establishing an effective low-energy Hamiltonian based on first principle calculations, we study the behavior of the local density of states of Co adatom on external parameters, such as magnetic field and gating. It is shown that the Kondo resonance with the Kondo temperature of the order of a few Kelvins can emerge by fine-tuning the chemical potential. The evolution and splitting of the Kondo peak with external magnetic field is also analyzed. Furthermore, it is shown that the spin polarization of adatom's spectral function in the presence of magnetic field can be relatively large, and it is possible to tune the polarization and its sign by electrical means.
STRENGTH, MODULUS OF ELASTICITY AND SHRINKAGE BEHAVIOUR OF CONCRETE CONTAINING WASTE CARPET FIBER

This paper presents test results on some physical and mechanical properties of concrete containing fiber from recycled carpet waste. Five concrete mixes namely plain concrete (PC) i.e. concrete without carpet fiber, as control and carpet fiber reinforced concrete (CFRC) mixes containing 0.5%, 1.0%, 1.5% and 2.0% polypropylene (PP) waste carpet fibers were made and tested for compressive, tensile and flexural strengths, modulus of elasticity and shrinkage at curing periods of 1, 7 and 28 days. It has been found that the addition of carpet fiber reduced the workability and density of concrete. Concrete containing carpet fiber exhibited lower compressive strength and modulus of elasticity than plain concrete. The carpet fibers, however, effectively improved the splitting tensile and flexural strengths of concrete. The obtained values of shrinkage revealed that the shrinkage strain of carpet fiber reinforced concrete was higher than that of plain concrete. On the basis of short-term investigation, the one-year shrinkage values of both plain concrete and concrete containing carpet fiber were also predicted by extrapolating the data obtained during this period. The results obtained in this study indicate that waste carpet fiber can suitably be used as fiber reinforcement in concrete with satisfactory performance.
Controle de acesso na plataforma de nuvem federada BioNimbuZ

A federated cloud environment consists of interconnected clouds that share resources with each other using an interface transparent to the user. In these environments, ensuring the safety of users is not an easy task, as it is necessary to take into account the individual characteristics of the federation providers, which is one of the reasons that hinder the full adoption of these environments by companies and organizations. This work deals with the problem of security in federated clouds, especially BioNimbuZ platform. In this context, this work proposes the use of an attribute-based access control model to decide whether or not a user can access a given resource. The experiments conducted show that the model is able to efficiently restrict resources access to authorized users.
