Biotemplated hierarchical nickel oxide supercapacitor electrodes

This paper presents fabrication and characterization of Tobacco mosaic virus (TMV)-templated hierarchical nickel oxide (NiO) supercapacitor electrodes. The hierarchical NiO electrode was created by integrating silicon (Si) micropillars with thermally oxidized nickel (Ni)-coated TMVs. SEM images taken after the high temperature oxidation process verified the robustness of the bio-nanotemplates, while the formation of Ni(core)/NiO(shell) structure around the rod-like virus was confirmed by scanning transmission electron microscopy (STEM). Electrochemical characterization showed that the capacitance for TMV structured Ni/NiO electrodes continuously increases for the first 500 cycles, with significantly higher, non-linear increase for the hierarchical versus TMV-only (nanostructured) electrodes. Further electrochemical and SEM analysis support the hypothesis that the capacity increase is due to the increase in electroactive sites of the nanostructured NiO throughout the initial charge/discharge cycles.
On Tree Detection, Counting & Post- Harvest grading of fruits Based on Image Processing and Machine Learning Approach-A Review

— This paper reports involvement of image processing and machine vision technique to detect and count of fruits on-tree, in field condition, have been reviewed. In addition, this paper also associated with the grading of fruits in post-harvesting. Different types of algorithms are available for counting and to extract the feature of fruit characters by capturing the on-tree fruit image by any conventional RGB camera. With the help of this counting algorithm and feature extraction technique, fruit is detected and counted. This work also surveys grading method applied to the post-harvest fruits. Grading method involves: identification of mature & immature fruits, intact & diseased fruits and also predict the weight of the fruit from its shape. The grading of fruit can be done by using different types of the classifier. The main features, drawback and future prospective of previous work in this area are summarized.
Impulsive modeling and control of a new chaotic system

In this paper, we consider impulsive modeling and control of a new chaotic system with time-varying impulse intervals. The new chaotic system is derived from Lorenz system, Chen system and Lu system. By establishing an effective tool of a set of inequalities, we analyze the asymptotic stability of impulsive control the new chaotic system and obtain some new less conservative conditions. Based on the stability analysis, we design a novel impulsive controller with time-varying impulse intervals. Illustrative examples are provided to show the feasibility and effectiveness of our method finally.

[Poster] Touch gestures for improved 3D object manipulation in mobile augmented reality

This work presents three techniques for 3D manipulation on mobile touch devices, taking the specifics of mobile AR scenes into account. We compare the common direct manipulation technique with two indirect techniques, which utilize only the thumbs to perform the transformations. The evaluation of the manipulation variants is conducted in a mixed reality (MR) environment which takes advantage of the controlled conditions of a full virtual reality (VR) system. A study with 18 participants shows that the two-thumb method tops the other techniques. It performs better with respect to the total manipulation time and total number of gestures.
MODELS OF PROTEIN FOLDING

In an attempt to explore the understanding of protein folding mechanism, various models have been proposed in the literature. Advances in recent experimental and computational techniques rationalized our understanding on some of the fundamental features of the protein folding pathways. The goal of this review is to revisit the various models and outline the essential aspects of the folding reaction.
Adverbiale im Deutschen: Untersuchungen zu ihrer Stellung und Interpretation. By Karin Pittner. (Studien zur deutschen Grammatik, 60.) Tübingen: Stauffenburg, 1999. Pp. viii, 390. Paper. DM 148,00.

Adverbs, their placement, and their licensing conditions have been the focus of a number of recent (language-specific and crosslinguistic) studies (e.g., Alexiadou 1997, Ernst 1998, Laenzlinger 1998, and Cinque 1999, among others). Pittner's book complements these studies by offering a detailed investigation of adverbials in German. The book is divided into six main chapters. In what follows I give a brief critical overview of the contents of the study, and I finish my discussion by addressing some general theoretical issues treated by Pittner.
Defect-oriented analysis of memory BIST tests

This paper describes a defect-oriented analysis of 4 BIST tests that are used to test a commercial 6-port embedded SRAM. We will examine the realistic fault and defect coverages of these memory BIST tests. We also uncover the subtle effect that addressing order has on the coverage that a test can provide. In addition, we will show that the coverage that a test provides can vary from row to row depending on the addressing scheme.
La interrogación retórica.

El fenomeno conocido habitualmente con el nombre de interrogacion retorica ha atraido desde antiguo la atencion no solo de los gramaticos, sino tambien, y muy especialmente, de los maestros de Oratoria, de los tratadistas de Retorica, de los filosofos y de los logicos. Sin embargo, no siempre los estudios y las consideraciones de los especialistas en cada una de estas materias alcanzaban la difusion suficiente entre los de las otras disciplinas. El resultado es, evidentemente, una enorme dispersion de los conocimientos. Por ello, en el momento en que la Linguistica se ha visto enriquecida con las aportaciones de la nueva logica simbolica, y cuando se hace cada vez mas patente la necesidad de completar los niveles tradicionales de analisis del lenguaje con el de la Pragmatica, parece que resulta conveniente revisar esta cuestion, a la luz de las concepciones actuales de los estudios linguisticos. De este modo, se pretende obtener un conocimiento mas integrado, y avanzar, a la vez, algunas hipotesis explicativas acerca de su funcionamiento. Antes de entrar de lleno en el tema que nos ocupa, conviene hacer algunas precisiones conceptuales. Para evitar posibles errores, parece imponerse la necesidad de establecer una distincion clara entre lo que podi-jamos llamar «modalidad» de la oracion, de naturaleza gramatical y caracterizada por rasgos formales, y el uso de los enunciados, sometido a los principios pragmaticos que regulan la conversacion.

Effect of conditioned stimulus exposure during slow wave sleep on fear memory extinction in humans.

STUDY OBJECTIVES Repeated exposure to a neutral conditioned stimulus (CS) in the absence of a noxious unconditioned stimulus (US) elicits fear memory extinction. The aim of the current study was to investigate the effects of mild tone exposure (CS) during slow wave sleep (SWS) on fear memory extinction in humans. DESIGN The healthy volunteers underwent an auditory fear conditioning paradigm on the experimental night, during which tones served as the CS, and a mild shock served as the US. They were then randomly assigned to four groups. Three groups were exposed to the CS for 3 or 10 min or an irrelevant tone (control stimulus, CtrS) for 10 min during SWS. The fourth group served as controls and was not subjected to any interventions. All of the subjects completed a memory test 4 h after SWS-rich stage to evaluate the effect on fear extinction. Moreover, we conducted similar experiments using an independent group of subjects during the daytime to test whether the memory extinction effect was specific to the sleep condition. PARTICIPANTS Ninety-six healthy volunteers (44 males) aged 18-28 y. MEASUREMENTS AND RESULTS Participants exhibited undisturbed sleep during 2 consecutive nights, as assessed by sleep variables (all P > 0.05) from polysomnographic recordings and power spectral analysis. Participants who were re-exposed to the 10 min CS either during SWS and wakefulness exhibited attenuated fear responses (wake-10 min CS, P < 0.05; SWS-10 min CS, P < 0.01). CONCLUSIONS Conditioned stimulus re-exposure during SWS promoted fear memory extinction without altering sleep profiles.
What Paint Can Tell Us: A Fractal Analysis of Neurological Changes in Seven Artists

Objective: The notion that artistic capability increases with dementia is both novel and largely unsupported by available literature. Recent research has suggested an emergence of artistic capabilities to be a by-product of involuntary behaviour seen with dementia, as opposed to a progression in original thinking (de Souza, et al., 2010). A far more complementary explanation comes from Hannemann (2006), who suggests that art offers an outlet for dementia patients to refine and sharpen their cognitive abilities. As dementia severely impedes linguistic skills, non-verbal therapeutic methods such as painting can permit dementia patients to express themselves in a way not possible verbally. Fractal analysis has been used to determine the authenticity of major works of art. Taylor et al., (1999) found that through a fractal analysis of Jackson Pollock’s paintings it was possible to distinguish authentic works from a large collection of fakes, demonstrating that when artists paint they instill within their work their own pattern of unique fractal behaviour. Can age-indexed variations in the fractal dimension of the works of artists anticipate specific cognitive deteriorations? Method: To answer this question we analysed age-related variations in the fractal dimension of a large corpus of digital images (n = 2092) of work created by seven notable artists who experienced both normal ageing and neurodegenerative disorders. Results: The results of our analysis showed that patterns of change in the fractal dimension of the paintings differentiated artists who suffered neurological deterioration from those of normal aging controls. Conclusions: These findings are of importance for two reasons. Our work adds to studies that demonstrate that fractal analysis has the potential to determine the provenance of paintings. Secondly, our work suggests that may be possible to identify a-typical changes in the structure of an artist’s work; changes that may be early indicators of the onset of neurological deterioration.
The space of admittance control laws that guarantees force-assembly with friction

If an admittance control law is properly designed, a workpiece can be guided into a fixture using only the contact forces for guidance (force-assembly). Using an optimization procedure, a single accommodation control law that allows force-assembly at the maximum value of friction is obtained. For the purpose of the accommodation control law design, a set of linear sufficient conditions is used to generate accommodation basis matrices. Any nonnegative linear combination of the accommodation basis matrices that, when combined, yields a positive definite accommodation matrix, is guaranteed to provide force-assembly at (or below) the value of friction specified. <<ETX>>
Sequential improvement of anxiety, depression and anhedonia with sertraline treatment in patients with major depression

Objective: To establish the therapeutic effect profile of sertraline in major depression. It was hypothesized that the antidepressant effect of sertraline showed three phases: Phase 1 where improvements in anxiety are most pronounced; Phase 2 where the greatest improvements are in depressive symptoms; and Phase 3 where the symptoms of anhedonia show the most improvement. To test this hypothesis, an 8‐week, open‐label study was conducted.
Cationic peptide of the male reproductive tract, HE2alpha, displays antimicrobial activity against Neisseria gonorrhoeae, Staphylococcus aureus and Enterococcus faecalis.

OBJECTIVES To analyse the in vitro antimicrobial effects of synthetic HE2alpha peptide against Neisseria gonorrhoeae, Staphylococcus aureus and Enterococcus faecalis. METHODS The HE2alpha peptide was synthesized based on the C-terminal sequence of the HE2alpha protein. The bacterial strains tested included two antibiotic-susceptible strains of N. gonorrhoeae and four antibiotic-resistant clinical isolates, as well as S. aureus ATCC 29213 and E. faecalis ATCC 29212. Susceptibility determinations were carried out either in 0.7% casamino acids for N. gonorrhoeae isolates or in 10 mM phosphate buffer for S. aureus and E. faecalis strains. Antibacterial effects were measured in a dose- and time-dependent manner. After exposure to the peptide in solution, the number of viable cells was determined by counting colony forming units (cfu). RESULTS The HE2alpha peptide exhibited time- and dose-dependent antibacterial effects on all N. gonorrhoeae isolates tested. S. aureus and E. faecalis strains were also susceptible to the peptide. All strains tested were susceptible to the peptide at high concentrations (50 or 100 mg/L) and some strains were susceptible to a peptide concentration of 25 mg/L. CONCLUSIONS The peptide HE2alpha, which is derived from the male urogenital tract, exhibits antibacterial activity against both gram-positive and gram-negative pathogens in vitro. The peptide is active against both antibiotic-susceptible and -resistant N. gonorrhoeae isolates. Further investigation of the antimicrobial properties of the peptide is warranted.
Activation of neuropeptide S‐expressing neurons in the locus coeruleus by corticotropin‐releasing factor

• Neuropeptide S (NPS) and its cognate receptor represent a recently discovered transmitter system in the brain modulating anxiety‐ and stress‐related behaviour. • Using a transgenic NPS‐EGFP‐expressing mouse line, the present study shows that NPS‐expressing neurons are situated in close proximity to corticotropin‐releasing factor (CRF)‐containing fibres at the locus coeruleus in the brain stem and express the CRF receptor 1 (CRF1). • CRF depolarizes NPS neurons via activation of the CRF1 receptor through two different ionic mechanisms (a decrease in potassium and an increase in cation conductance) involving the cAMP signalling pathway. • After acute immobilization stress, NPS neurons display an increased expression of c‐fos. • This study identifies a mechanism by which stress‐related CRF release might activate NPS neurons in the brain stem, thereby triggering NPS release in target areas such as the amygdala, and functioning as a negative feedback control to buffer stress responsiveness.
Contribution à l'étude de la stabilité d'impulsion à impulsion d'un émetteur état solide pour radar

La stabilite d'impulsion a impulsion est une caracteristique primordial d'un radar de surface. Elle represente la variation de phase et d'amplitude entre impulsions successives du signal hyperfrequence et entraine une degradation (perte de detection, creation de fausse alarme) du fonctionnement du radar. Notre travail a principalement consiste en une meilleure definition et comprehension de ce probleme complexe de stabilite qui presente une importance capitale lors de la conception et de la certification d'un equipement radar. Apres un rappel du principe general de fonctionnement d'un radar impulsionnel, nous avons defini la stabilite de phase et d'amplitude d'impulsion a impulsion, introduit les differentes causes d'instabilite et presente leurs consequences. Puis, nous avons aussi insiste sur les differentes approches mathematiques quantifiant ces phenomenes et montre en particulier que suivant le type de methode retenue (temporelle ou frequentielle) les resultats obtenus pouvaient varier de facon significative. Nous avons explique ces ecarts par le fait que les methodes temporelles caracterisent principalement la stabilite de l'emetteur seul alors que la methode frequentielle caracterise plutot la stabilite du systeme radar global. L'essentiel de notre travail a ete consacre a l'analyse des causes d'instabilite des modules emetteurs etat solide et a la mise en oeuvre de methodologies specifiques pour les caracteriser. Nous avons en particulier montre l'influence predominante des effets thermiques transitoires sur la stabilite d'un emetteur etat solide loin devant les effets liees aux fluctuations de tension d'alimentation et de desadaptation d'impedance. L'etude des phenomenes de recombinaison de plusieurs signaux issus d'amplificateurs ou de chaines d'amplification utilises dans les modules emetteurs et des consequences sur la stabilite a permis d'obtenir des resultats tres significatifs et nouveaux. Nous avons confirme que dans la quasi totalite des cas, la recombinaison s'accompagnait d'une amelioration de la stabilite. Cette amelioration est surtout notable pour la stabilite de phase et semble liee principalement a la compensation des composantes deterministes de l'instabilite.
Content and Type as Orthogonal Modeling Features: a Study on User Interest Awareness in Entity Subscription Services

—Real-word entities can be mapped to unique entity identiﬁers through an Entity Name System (ENS), to systematically support the re-use of these identiﬁers and disambiguate references to real world entities in the Web. An entity subscription service informs subscribed users of changes in the descriptive data of an entity, which is a set of free-form attribute name-value pairs. We study the design, implementation and application of an adaptable, push-policy subscription service, within a large-scale ENS. The subscription system aims to deliver ranked descriptions of the changes on entities, following user preferences through a feedback-driven adaptation process. Within this paper, we offer a novel approach based on the discrimination between the content (descriptive aspect) and the type (directly quantiﬁable or binary aspects) of information instances (i.e., entity changes in our case). We study and evaluate two different approaches of adaptation to user interests: one that only manages constant user preferences and one that adapts to interest shifts of the users. We evaluate the learning curve of the variations of the system, the utility of the content-type discrimination, as well as the effectiveness of modeling user behavior for random interest shifts of the user. The experiments demonstrate good results, especially in the system’s content-aware adaptation aspect, which takes into account user interest shifts. We also extract a set of useful conclusions concerning the detection of user interest shifts, based on feedback, as well as the relation between the user interest shift frequency and the optimality of learning memory window size.
An Innovative Model to Predict Pediatric Emergency Department Return Visits

Objectives Return visit (RV) to the emergency department (ED) is considered a benchmarking clinical indicator for health care quality. The purpose of this study was to develop a predictive model for early readmission risk in pediatric EDs comparing the performances of 2 learning machine algorithms. Methods A retrospective study based on all children younger than 15 years spontaneously returning within 120 hours after discharge was conducted in an Italian university children's hospital between October 2012 and April 2013. Two predictive models, artificial neural network (ANN) and classification tree (CT), were used. Accuracy, specificity, and sensitivity were assessed. Results A total of 28,341 patient records were evaluated. Among them, 626 patients returned to the ED within 120 hours after their initial visit. Comparing ANN and CT, our analysis has shown that CT is the best model to predict RVs. The CT model showed an overall accuracy of 81%, slightly lower than the one achieved by the ANN (91.3%), but CT outperformed ANN with regard to sensitivity (79.8% vs 6.9%, respectively). The specificity was similar for the 2 models (CT, 97% vs ANN, 98.3%). In addition, the time of arrival and discharge along with the priority code assigned in triage, age, and diagnosis play a pivotal role to identify patients at high risk of RVs. Conclusions These models provide a promising predictive tool for supporting the ED staff in preventing unnecessary RVs.
Hacia la formalización del razonamiento ecuacional sobre mónadas

Una de las grandes ventajas de los lenguajes funcionales puros es que permiten ser razonados ecuacionalmente, de esta forma, se facilita la verificacion de su correccion. Pero esta pureza impide los efectos computacionales necesarios para que este tipo de programas tengan interaccion alguna, es por esto que las funciones monadicas, que se encargan de encapsular estos efectos y asi conservar la pureza, representan una estructura importante dentro de los lenguajes funcionales. Sin embargo, debido a que las monadas poseen una estructura imperativa, no se ha podido establecer un enfoque aceptado para razonar ecuacionalmente sobre estas. Por tanto, se pretende formalizar (desde un punto de vista computacional) en Agda la propuesta realizada por Gibbons y Hinze en [7] minimizando asi los errores en los pasos de cada una de las demostraciones. Asi pues, se presentan los conceptos basicos que permitan comprender como se razona sobre los programas y se muestra mediante un ejemplo la posibilidad de formalizar este razonamiento.
Un modèle de diffusion des produits nouveaux intégrant un effet d'imitation variable

—Les auteurs proposent un nouveau modèle de diffusion des produits. Extension du modèle de Bass, il surmonte trois limites des modèles actuels d'adoption. Tout d'abord, les modèles actuels supposent que l'effet du bouche à oreille reste constant pendant toute la durée de la diffusion. Pourtant, pour de nombreuses innovations, cet effet a tendance à croître, diminuer ou rester constant. En deuxième lieu, les modèles existants restreignent la localisation du point d'inflexion sur les courbes de diffusion. Troisièmement, ces modèles supposent que la dynamique d'adoption avant et après le taux de pénétration maximal est identique. C'est-à-dire que la courbe est symétrique. En permettant à l'effet du bouche à oreille de varier systématiquement dans le temps, le modèle proposé permet à la courbe de diffusion d'être symétrique ou non, avec le point d'inflexion dépendant du processus de diffusion. Une analyse de données portant sur cinq biens de consommation durables illustre ce modèle.
