Electronic transport in p-type doped GaAs nanowires

It is shown that Mg can be used as a p-type nontoxic and noncarcinogenic alternative dopant in GaAs nanowires. The analysis of the temperature dependence of the electrical properties of individual nanowires shows that the electronic transport changes from conduction of free holes, above room temperature, to hopping conduction at lower temperatures. Two hopping conduction mechanisms were observed starting from Mott-VRH and transiting to ES-VRH as temperature drops. The analysis of the hopping conduction allows extracting the values of electrical transport parameters in the NWs. The average doping levels were found to change from nanowire to nanowire. This anomaly was explained in terms of variations of growth rate from wire to wire due to the characteristic growth mechanism of free-standing nanowires, as well as due to the polytypism in the NWs.
Teaching Visualization for Large and Diverse Classes on Campus and Online

We present how principles and methods from active learning can be integrated and applied to a large undergraduate visualization course for students with a wide range of different educational backgrounds. The course covers the main principles of visualization (theory), showcases examples of visualizations and the main visualization types (visualization literacy), and covers visual design and critical discussions of visualization designs (design). In a final project, students have to design and develop their own web-based interactive visualizations using Javascript and D3 (programming). We describe how we have adjusted our previous course to include state-of-the art principles of active learning, with the goal to (a) increase student engagement, and (b) increase knowledge transfer. Quantitative and qualitative student feedback, as well as Q scores show successful engagement of students. The results of the midterm exam as well as the final projects indicate that we were successful at transferring knowledge about visualization theory, visualization literacy, design and programming.
Comparison of the antidepressant effects of venlafaxine and dosulepin in a naturalistic setting

The relative efficacy of the various classes of antidepressants has not been established. Observational studies in naturalistic settings are important in evaluating treatment outcomes with antidepressants, since controlled clinical trials include only a minority of patients present in clinical practice. This study sought to evaluate in a naturalistic setting the treatment outcomes of dosulepin and venlafaxine for patients with depressive episodes. At the university hospital in Copenhagen, Denmark, between 1998 and early 2001, the first-line treatment for psychiatric inpatients with depression was dosulepin; after that time, venlafaxine was the first-line medication. We compared the treatment outcomes among inpatients during the respective periods. There was no significant difference in the primary outcome parameters between the two groups. A tendency in favour of dosulepin confirmed by a post-hoc analysis suggested that the failure to achieve significant difference was related to a type 2 error. However, missing data and possible confounders related to the different treatment periods weaken the results. This naturalistic study showed a non-significant trend for poorer treatment outcomes (probably because of an underpowered design) after replacing dosulepin with venlafaxine as first-line drug for depression in a naturalistic inpatient setting.
TINTURA EN BAÑOS DE REUTILIZACIÓN DIRECTA: MICROFIBRAS DE POLIÉSTER CON COLORANTES DISPERSOS •)

Las presiones medioambientales sobre la industria textil y el consumo de agua y energia de dicho sector, llevan a la adopcion de medidas que influyen directamente sobre los procesos industriales de tintura. Disminuir el impacto medioambiental optimizando procesos para conseguir mejorar el nivel de agotamiento y/o reutilizar los banos finales, con o sin tratamiento intermedio, son algunas de las medidas que se vienen aplicando. En este trabajo se estudiara el caso de reutilizaciones directas de banos de tintura con CI Azul Disperso 56 y microfibras de poliester, con el objeto de evaluar su comportamiento en cineticas no isotermicas en el caso de 25 reutilizaciones a partir del bano original. A partir de los resultados obtenidos puede observarse una tendencia del % de agotamiento con el numero de reutilizaciones. Disminuye hasta la 5o reutilizacion, manteniendose aproxima-damente constante des de la 6a hasta la numero 25.
Valuing the Future

Normative discounted utility theory specifies that the values of all future outcomes (for example, those related to health and money) should be discounted at a constant rate. Two experiments demonstrated that, contrary to this prescription, decision makers use different discount rates for health-related decisions and money-related decisions. Temporal discount ings for health and money were similar in that both demonstrated two biases previously found in monetary decisions: discount rates were inversely related to magnitude of outcome and length of delay. The relatively large discount rates used by the subjects suggest why it is often difficult to implement preventive health measures that improve future health. Key words: discounting; intertemporal choice; health decisions. (Med Decis Making 1995;15:373- 386)
Six-Degree-of-Freedom Localization using an Unscented Kalman Filter for Planetary Rovers

In this paper, we propose an efficient solution to 6-d.o. f. localization using an unscented Kalman filter (UKF) for planetary rovers. The solution is a technique using a modified UKF for accurate planetary rover localization. The technique is able to cope with problems that occur frequently on other planetary surfaces: wheel slip, pulsive noise of visual odometry (VO) and gyro drift. To solve these problems, the technique estimates a slippage ratio with the UKF, the accuracy of the VO with the number of inliers of feature points and sensor usefulness with a gyrodometry model. Experimental results of rover runs over rough terrain are presented and discussed; the effectiveness of proposed method and its components is shown.
B-spline representation of active contours

In this paper, we propose two cubic B-spline representations have a lot of advantages such as compact and local control. One is based on registration by a least squares method. The evolutions of an active contour are restricted by an affine transformation which is calculated by corresponding points between pre-deformed and deformed curves during the evolution process. The other is based on dynamic programming. We applied it to control points. It is an energy minimizing spline controlled by control points. We use dynamic programming as an energy minimization method for both approaches. The proposed algorithms is applied to both synthetic binary images and MRI images.
Screen Printing of Multilayered Hybrid Printed Circuit Boards on Different Substrates

This paper reports on the successful fabrication of a multilayered hybrid printed circuit board (PCB) for applications in the consumer electronics products, medical technologies, and military equipment. The PCB was fabricated by screen-printing silver (Ag) flake ink, as metallization layer, and UV acrylic-based ink, as dielectric layer, on different substrates such as paper, polyethylene terephthalate, and glass. Traditional electronic components were attached onto the printed pads to create the multilayered hybrid PCB. The feasibility of the hybrid PCB was demonstrated by integrating an embedded microcontroller to drive an liquid-crystal display (160 × 100 pixels). In addition, the amount of the ink spreading after printing, the effect of bending on the printed lines, and the effect of the roughness of the substrates on the resistance of the printed lines was investigated. It was observed that the resistance of the lines increased by ≈1.8%, after 10000 cycles of bending, and the lowest resistance of 1.06 Ω was measured for the 600 μm printed lines on paper, which had a roughness of 0.175 μm. The advantage of fabricating PCBs on flexible substrates is the ability to fold and place the boards on nearly any platform or to conform to any irregular surface, whereas the additive properties of printing processes allow for a faster fabrication process, while simultaneously producing less material waste in comparison with the traditional subtractive processes. The results obtained show the promising potential of employing screen printing process for the fabrication of flexible and light-weight hybrid PCBs.
Development of a Multitarget Real-Time TaqMan PCR Assay for Enhanced Detection of Francisella tularensis in Complex Specimens

ABSTRACT Tularemia is the zoonotic disease caused by the gram-negative coccobacillus Francisella tularensis. Its wide distribution in the environment poses a challenge for understanding the transmission, ecology, and epidemiology of the disease. F. tularensis is also considered a potential biological weapon due to its extreme infectivity. We have developed a multitarget real-time TaqMan PCR assay capable of rapidly and accurately detecting F. tularensis in complex specimens. Targeted regions included the ISFtu2 element and the 23kDa, fopA, and tul4 genes. Analysis of the four TaqMan assays demonstrated that three (ISFtu2, 23kDa, and tul4) performed within our established criterion of a detection limit of one organism. The combined use of the three assays was highly specific, displaying no cross-reactivity with the non-Francisella bacteria tested and capable of differentially diagnosing both F. tularensis and Francisella philomiragia. When the multitarget TaqMan assay (ISFtu2, 23kDa, and tul4) was compared to culturing, using environmentally contaminated specimens, the TaqMan PCR assay was significantly more sensitive than culturing (P ≤ 0.05). The sensitive and specific nature of this rapid multitarget TaqMan assay provides a valuable new tool that with future evaluations can be used for analyzing clinical specimens, field samples during bioterrorism threat assessment, and samples from outbreaks and for improving our understanding of the ecology and environmental prevalence of F. tularensis.
Extraction of points of interest from SAR tomograms

In this paper we present a SAR tomographic post-processing technique to extract point of interest from SAR tomograms. We propose a signal-to-noise index adapted to tomogram generated by SP-MUSIC-1 (single polarization, assuming 1 scatterer) that quantifies the separation of scatterer peak from other artifacts (noise,.). This index allows to remove artifacts caused by speckle noise, low SNR, error in orbit position, etc. The domain of validity of this approach is also analyzed over two different regions: isolated buildings and building surrounded with vegetation. Experiment results are shown using a multibaseline dataset acquired in L-band by DLR's experimental SAR (E-SAR) on a test site near Oberpfaffenhofen/Germany.
Recommender engine using cosine similarity based on alternating least square-weight regularization

By the growth of digital data which leads to more complex demands from user to find the information or items. Search engines solve most of the problems but have the drawback, it depends on the query/term that the user enter. The problem appears when the user forget or does not know the query that associated with the items. The Recommendation comes as a solution to provide personal information by studying the interaction of a user, user community, and items that have been recorded previously. Collaborative filtering as a method to provide personalized recommendations based on other users who have similar tastes. However, the results of collaborative filtering tend random, sometimes users need an item with similar genre/subjects. This paper discusses a model of a recommendation engine for new users with a method of collaborative filtering based on genre similarly with the aim of giving the smallest error with high precision. First filter we use Alternating Least Square-Weight Regularization (ALS-WR) is selected as algorithms for collaborative filtering. Second filter we use Cosine Similarity is selected as an algorithm for genre similarity. We use datasets from movielens.org. The RMSE on the first recommendation generated is 0.89 for 100K ratings, 0.86 for the 1M ratings, and 0.81 for the 10M rating. By iterative and training on larger data, it will make a better model, so RMSE can be smaller. They are concluded that ALS-WR able to deliver adaptive, with regulatory parameters that can be controlled and adjusted. The more data but the error on the wane, that is means this algorithm is suitable for growing data or big data. The item that has been sorted with the ALS-WR algorithm, letter approximated with cosine similarity, and with only 10 items movie displays with the highest degree of similarity, that be able to generate high precision.
Dynamic modelling of a two link flexible robot and experimental validation

The paper discusses the modelling issues for a two link flexible robot arm. The exact dynamic model of the robot arm is derived, and approximate forms suitable for the analysis and control design are proposed. The approach used here to derive an approximate finite dimensional model of the flexible robot arm is based on the Ritz expansion method. Simulations and experimental tests have been carried out to validate the approximate dynamic model of the robot.
Randomized controlled trial and cost‐effectiveness analysis of silver‐donating antimicrobial dressings for venous leg ulcers (VULCAN trial)

Antimicrobial silver dressings are used beneath graduated compression in the treatment of venous ulceration. There is little information on whether their use is effective. This was a prospective randomized trial and cost‐effectiveness analysis of silver‐donating versus non‐silver low‐adherence dressings in the treatment of venous leg ulcers.
Computational and Experimental Analysis of the Transmembrane Domain 4/5 Dimerization Interface of the Serotonin 5-HT1A Receptor

Experimental evidence suggests that most members of class A G-protein coupled receptors (GPCRs) can form homomers and heteromers in addition to functioning as single monomers. In particular, serotonin (5-HT) receptors were shown to homodimerize and heterodimerize with other GPCRs, although the details and the physiological role of the oligomerization has not yet been fully elucidated. Here we used computational modeling of the 5-HT1A receptor monomer and dimer to predict residues important for dimerization. Based on these results, we carried out rationally designed site-directed mutagenesis. The ability of the mutants to dimerize was evaluated using different FRET-based approaches. The reduced levels of acceptor photobleaching-Förster resonance energy transfer (FRET) and the lower number of monomers participating in oligomers, as assessed by lux-FRET, confirmed the decreased ability of the mutants to dimerize and the involvement of the predicted contacts (Trp1754.64, Tyr1985.41, Arg1514.40, and Arg1524.41) at the interface. This information was reintroduced as constraints for computational protein-protein docking to obtain a high-quality dimer model. Analysis of the refined model as well as molecular dynamics simulations of wild-type (WT) and mutant dimers revealed compensating interactions in dimers composed of WT and W175A mutant. This provides an explanation for the requirement of mutations of Trp1754.64 in both homomers for disrupting dimerization. Our iterative computational-experimental study demonstrates that transmembrane domains TM4/TM5 can form an interaction interface in 5-HT1A receptor dimers and indicates that specific amino acid interactions maintain this interface. The mutants and the optimized model of the dimer structure may be used in functional studies of serotonin dimers.
ABSORBED DOSE TO VERY LOW BIRTH WEIGHT INFANTS FROM 18F-FLUORODEOXYGLUCOSE

Abstract— The radiation absorbed dose to very low birth weight infants from 18F-fluorodeoxyglucose was investigated. Ten newborns undergoing clinical positron tomography lung imaging were included in this study. Two consecutive 45-min dynamic scans immediately following intravenous injection of fluorodeoxyglucose were acquired; the first was over the head, and the second was over the chest. Time-activity curves were generated for the brain, heart wall, lungs, and, when visible, the kidneys. The cumulated activity measurements obtained were for the entire organ masses; these masses were much smaller than the corresponding organ masses for the newborn mathematical model. Patient-specific dosimetry yielded average doses of 2.5 × 10−1 mGy MBq−1 for the brain, 6.8 × 10−1 mGy MBq−1 for the heart wall, 2.2 × 10−1 mGy MBq−1 for the kidneys, and 4.4 × 10−1 mGy MBq−1 for the lungs. The effective dose was estimated to be 2.1 × 10−1 mSv MBq−1, which is half that previously published for newborns but still an order of magnitude higher than that for adults.
Les appropriations de terres à grande échelle : Analyse du phénomène et propositions d'orientations

Les processus d'appropriation et de concentration des terres cultivables par de grandes entreprises dans de nombreux pays du Sud et de l'Est preoccupent societe civile, institutions internationales et gouvernements. Sur la base des contributions des membres du Comite technique " Foncier et developpement " et de membres d'un groupe de travail elargi, ce document caracterise les differentes situations observables sur la base des informations disponibles. Les auteurs s'interrogent sur le sens du mot investissement et sur les types d'investissement dont le monde a besoin pour garantir securite alimentaire et preservation de l'environnement. Ils distinguent les phenomenes de privatisation de ressources communes des phenomenes de concentration de terres deja reconnues proprietes privees et soulignent en quoi ces phenomenes sont ou non veritablement nouveaux. La question abordee fait partie des enjeux globaux du debut du XXIe siecle qui nous concernent tous. L'emploi, la creation de valeur ajoutee et sa distribution, la production de biens alimentaires et de services environnementaux relevent de l'interet general, et leur regulation ne peut se reduire au seul jeu des marches. Derriere le debat entre les differents modeles de production se cachent de veritables choix de societe. Les propositions sont construites autour de deux principes : 1. la defense des droits existants des populations sur la terre et les ressources et 2. la necessite de reconnaitre des droits collectifs permettant la compatibilite des usages et des droits privatifs individuels avec l'interet general. Elles sont declinees aux differents niveaux : national, regional et mondial. Les auteurs reconnaissent l'importance de la mise en place de mesures volontaires, mais soulignent que le probleme ne pourra etre traite en s'appuyant uniquement sur la bonne volonte d'entreprises socialement responsables. Ils invitent donc les differentes parties a : - contribuer des a present a la mise en place progressive d'un cadre juridique contraignant au niveau mondial ; - developper des politiques et des mecanismes qui remunerent le travail et l'efficacite economique et redistribuent les rentes qui n'auront pas pu etre eliminees, en mettant en place une fiscalite fonciere.

Are there Practical Alternatives to Alpha-Beta?

The success of the alpha-beta algorithm in game-playing has shown its value for problem solving in arti(cid:12)cial intelligence, especially in the domain of two-person zero-sum games with perfect-information. However, there exist di(cid:11)erent algorithms for game-tree search. This paper describes and assesses those proposed alternatives according to how they try to overcome the limitations of alpha-beta. We conclude that for computer chess no practical alternative exists, but many promising ideas have good potential to change that in the future.
Antioxidant and Cytoprotective Activities of Enzymatic Extracts from Rhizoid of Laminaria japonica

Rhizoid of Laminaria japonica was hydrolyzed with proteases and carbohydrases to obtain antioxidant materials. Oxygen radical absorbance capacity (ORAC) of the enzymatic extracts was evaluated and the Protamex extract (PE) exhibited the highest ORAC value. PE also potently scavenged 2,2-diphenyl-1-picrylhydrazyl radical, 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulphonic) acid cation radical, and hydrogen peroxide (H2O2) and had good reducing power. PE inhibited hydroxyl radical-induced DNA scission by measuring the conversion of supercoiled pBR322 plasmid DNA to the open circular form. The cytoprotective effect of PE against H2O2-induced hepatic cell damage was also investigated. PE showed a dose-dependent cytoprotective effect in cultured hepatocytes by inhibiting intracellular reactive oxygen species scavenging activity. In addition, PE up-regulated the expression of heme oxygenase-1, which is a cytoprotective enzyme, by activating translocation of nuclear factor-erythroid 2-related factor 2. Taken together, the enzymatic extract of rhizoid of L. japonica, particularly PE, may be useful for antioxidant additives.
A geometric approach to animating thin surface features in smoothed particle hydrodynamics water

We propose a geometric approach to animating thin surface features of smoothed particle hydrodynamics‐based water. Explicit interparticle connections are created among smoothed particle hydrodynamics particles to approximate the geometries of thin surfaces while addressing the issue of unresolved surface areas. The deformations measured on the connections actuate the animations of the surfaces by disconnecting the stretched and bent connections. The reconstruction of thin surfaces and the accuracy of the animation are improved by adding auxiliary particles over the connections via Poisson‐disk sampling.

Melatonin mitigates oxidative damage and apoptosis in mouse cerebellum induced by high‐LET 56Fe particle irradiation

Abstract: Cerebellum is a vital organ responsible for the motor coordination and recently it has been reported to be involved in cognitive function. Reactive oxygen species are implicated in neurodegeneration and cognitive disorders because of higher vulnerability of neuronal tissues. Therefore, the present study aimed at investigating the role of melatonin against high‐LET (linear energy transfer) 56Fe particle irradiation‐induced oxidative damage and apoptosis in the mouse cerebellum. Radiation‐induced oxidative damage was examined using a neuronal‐specific terminal deoxynucleotidyl transferase‐mediated nick end‐labeling (TUNEL), quantitative histopathology, DNA damage (comet assay), carbonyl content and 4‐HAE + MDA (4‐hydroxyalkenal + malondialdehyde) status of the cerebellum. Radiation exposure augmented the number of TUNEL positive cell, DNA migration in the comet tail and carbonyl and 4‐HAE + MDA level in the cerebellum. Melatonin pretreatment significantly inhibited the oxidative damage to biomolecules as well as cerebellar apoptosis. Melatonin‐treated irradiated mice showed higher counts of intact Purkinje cells as compared to vehicle‐treated irradiated mice. In addition, radiation induced augmentation of 8‐hydroxy‐2′‐deoxyguanosine (8‐OHdG) and a decline in the total antioxidant capacity in serum; these changes were also ameliorated by melatonin pretreatment. The present results provide evidence supporting the antioxidant and neuroprotective function of melatonin.
