Synthetic Antimicrobial Peptides Exhibit Two Different Binding Mechanisms to the Lipopolysaccharides Isolated from Pseudomonas aeruginosa and Klebsiella pneumoniae

Circular dichroism and 1H NMR were used to investigate the interactions of a series of synthetic antimicrobial peptides (AMPs) with lipopolysaccharides (LPS) isolated from Pseudomonas aeruginosa and Klebsiella pneumoniae. Previous CD studies with AMPs containing only three Tic-Oic dipeptide units do not exhibit helical characteristics upon interacting with small unilamellar vesicles (SUVs) consisting of LPS. Increasing the number of Tic-Oic dipeptide units to six resulted in five analogues with CD spectra that exhibited helical characteristics on binding to LPS SUVs. Spectroscopic and in vitro inhibitory data suggest that there are two possible helical conformations resulting from two different AMP-LPS binding mechanisms. Mechanism one involves a helical binding conformation where the AMP binds LPS very strongly and is not efficiently transported across the LPS bilayer resulting in the loss of inhibitory activity. Mechanism two involves a helical binding conformation where the AMP binds LPS very loosely and is efficiently transported across the LPS bilayer resulting in an increase in inhibitory activity. Mechanism three involves a nonhelical binding conformation where the AMP binds LPS very loosely and is efficiently transported across the LPS bilayer resulting in an increase in inhibitory activity.
Loop Length of Plain Single Weft Knitted Structure with Elastane

For decades, scientists have been trying to define relationships among yarn parameters, knitted fabric parameters, and knitting parameters with loop models. Recently, the geometrical loop models have returned to focus as they assist finding the effective parameters which cause dimensional changes during relaxation. Furthermore, they help designing knitted structures for technical applications and obtaining computer simulations of knitted structures. In the past, geometrical loop models considered more or less porous structures and the yarns used were mostly conventional, without elastane. The behavior and characteristics of compact knitted fabrics made from elasticized yarns have been investigated only recently. In general, mostly the structures with plated elastane threads have been analyzed. The aim of the research was to study the geometrical parameters (yarn thickness, loop width, loop height, fabric thickness, loop length) of plain single weft knitted structures made from various elasticized yarns, in comparison to equivalent structures made from conventional yarns. In the study, the most frequently applied loop models for the loop length calculations were evaluated with the emphasis on their adequacy for elasticized knitted structures. A new loop model for an elasticized weft knitted structure based on the multiple linear regressions was defined.
From High Intellectual Potential to Asperger Syndrome: Evidence for Differences and a Fundamental Overlap—A Systematic Review

Background: An increasing number of clinicians point to similar clinical features between some children with High Intellectual Potential (HIP or “Giftedness” = Total IQ > 2 SD), and children with Autism Spectrum Disorder (ASD) without intellectual or language delay, formerly diagnosed with Asperger Syndrome. Some of these common features are social interaction impairments, special interests, and in some cases high-verbal abilities. The aim of this article is to determine whether these similarities exist at more fundamental levels, other than clinical, and to explore the literature in order to provide empirical support for an overlap between ASD and HIP. Method: First, comparative studies between ASD and HIP children were sought. Because of a lack of data, the respective characteristics of ASD and HIP subjects were explored by a cross-sectional review of different areas of research. Emphasis was placed on psychometric and cognitive evaluations, experimental and developmental assessments, and neurobiological research, following a “bottom-up” procedure. Results: This review highlights the existence of similarities in the neurocognitive, developmental and neurobiological domains between these profiles, which require further study. In addition, the conclusions of several studies show that there are differences between HIP children with a homogeneous Intellectual Quotient profile and children with a heterogeneous Intellectual Quotient profile. Conclusion: HIP seems to cover different developmental profiles, one of which might share features with ASD. A new line of investigation providing a possible starting-point for future research is proposed. Its implications, interesting from both clinical and research perspectives, are discussed.
Group-Based Authentication and Key Agreement With Dynamic Policy Updating for MTC in LTE-A Networks

Machine type communication (MTC) is an important mobile communication approach in the long-term evaluation-advanced (LTE-A) networks. To meet the MTC security requirements, the access authentication processing of MTC devices needs to follow the evolved packet system-authentication and key agreement (EPS-AKA), a protocol defined in the third generation partnership project (3GPP) standard. However, in the emergence of group-based communication scenarios, an independent authentication processing for each MTC device will cause signal congestion in the networks. In addition, the access-policy updating has always been an issue when constructing authentication schemes. In this paper, we propose a group-based AKA (GR-AKA) protocol with dynamic policy updating. Specifically, we choose an asynchronous secret share scheme combining with Diffie-Hellman key exchange scheme to implement distributed authentication and session key establishment in the LTE-A networks, and to achieve dynamic MTC-device access authority updating. Compared with other authentication protocols in the LTE-A networks, our method could not only authenticate several MTC devices simultaneously but also dynamically update the access-policy to control the access authority of MTC devices. Extensive analysis and experiment results have shown the efficiency and efficacy of proposed protocol.
Perspectives of Prospective Elementary School Teachers on Feedback in the Mathematics Instruction I and II Courses.

The purpose of this study was to examine prospective elementary teachers' views on the feedback provided by the instructor and their peers during the courses, Mathematics Instruction I and II, and its contribution to their learning. Forty participants were regularly given feedback by the instructor and their peers while they were taking Mathematics Instruction I and II in the 2013-2014 academic year. At the end of the academic year, a survey form was administered to them. The form contained open-ended questions designed for this study. The form contained open-ended questions designed for this study. The data, which were analyzed qualitatively, showed that prospective elementary teachers consider the feedback provided by the instructor as mostly descriptive, whereas the peer feedback as mostly evaluative. In addition, the former made a more positive contribution to the participants’ performance, since it offered more guidance. Key words: Feedback, characteristics of effective feedback, instructor feedback, peer feedback.
Supersymmetric defects in the Maldacena-Núñez background

We find supersymmmetric configurations of a D5-brane probe in the Maldacena-Nunez background which are extended along one or two of the spatial directions of the gauge theory. These embeddings are worldvolume solitons which behave as codimension two or one defects in the gauge theory and preserve two of the four supersymmetries of the background.
A time-space tradeoff for Boolean matrix multiplication

A time-space tradeoff is established in the branching program model for the problem of computing the product of two n*n matrices over a certain semiring. It is assumed that each element of each n*n input matrix is chosen independently to be 1 with probability n/sup -1/2/ and to be 0 with probability 1-n/sup -1/2/. Letting S and T denote expected space and time of a deterministic algorithm, the tradeoff is ST= Omega (n/sup 3.5/) for T<c/sub 1/n/sup 2.5 /and ST Omega (n/sup 3/) for T<c/sub 2/n/sup 2.5/, where c/sub 1/,/sub /c/sub 2/ >0. The lower bounds are matched to within a logarithmic factor by upper bounds in the branching program model. Thus, the tradeoff possesses a sharp break at T= Theta (n/sup 2.5/). These expected case lower bounds are also the best known lower bounds for the worst case. <<ETX>>
A comparison of galaxy merger history observations and predictions from semi-analytic models

Mergers are predicted in all cosmological models involving cold dark matter (CDM) to be one of the dominant channels whereby galaxies accrete mass. In this paper, we present a detailed analysis of predicted galaxy-galaxy merger fractions and rates in the Millennium simulation and compare these with the most up to date observations of the same quantities up to z ∼ 3. We carry out our analysis by considering the predicted merger history in the Millennium simulation within a given time interval, as a function of stellar mass. This method, as opposed to pair fraction counts, considers mergers that have already taken place, and allows a more direct comparison with the observed rates and fractions measured with the concentration-asymmetry-clumpiness (CAS) method. We examine the evolution of the predicted merger fraction and rate in the Millennium simulation for galaxies with stellar masses M * ∼ 10 9 -10 12 M ⊙ . We find that the predicted merger rates and fractions match the observations well for galaxies with M * > 10 11 M ⊙ at z 2 for M * > 10 11 M ⊙ systems. At z > 2, the simulations underpredict the observed merger fractions by a factor of 4-10. The shape of the predicted merger fraction and rate evolutions are similar to the observations up to z ∼ 2, and peak at 1 10 11 M ⊙ , which remains high at z 10 11 M ⊙ at z > 1, and a lack of merger events between lower mass galaxies.
Emotion-based choice

In this article the authors develop a descriptive theory of choice using anticipated emotions. People are assumed to anticipate how they will feel about the outcomes of decisions and use their predictions to guide choice. The authors measure the pleasure associated with monetary outcomes of gambles and offer an account of judged pleasure called decision affect theory. Then they propose a theory of choices between gambles based on anticipated pleasure. People are assumed to choose the option with greater subjective expected pleasure. Similarities and differences between subjective expected pleasure theory and subjective expected utility theory are discussed. Emotions have powerful effects on choice. Our actual feelings of happiness, sadness, and anger both color and shape our decisions. In addition, our imagined feelings of
Classification of barrier options

For a given level of accuracy in option prices, the paper considers the problem of deciding when exactly, as one or more of the pricing parameters change, a barrier option degenerates into a simpler type of option. This problem is meaningful in the real world where option prices are always determined within a certain level of accuracy. The problem is reduced to finding certain critical values of the initial stock price, and this is achieved through a probability-based approach.
Design of Low Noise Amplifiers at 10 GHZ and 15 GHZ for Wireless Communication Systems

In this study, design and simulation of 15GHZ and 10GHZ Low Noise Amplifiers (LNA) have been explored. The simulation has been performed by using the Agilent Advanced Design System (ADS) Software. Tuning and optimization tools of ADS software have been used to optimize results. The minimum Noise Figure (NFmin) of the High Electron Mobility Transistor (HEMT) device in our simulation, is lower than previous works. We have designed a 15GHZ LNA based on three design methods basing on the lumped, the distributed and the radial stub elements. The scattering parameters of 15GHZ designed amplifier in the following manner, input return loss (S11), output return loss (S22), forward gain (S21), and isolation (S12) are -17.15dB, -16.92dB and 14.35dB as follow as -17.023 dB, respectively. Furthermore, noise figure of the 15GHZ designed amplifiers is 0.92 dB. Furthermore, the simulation results show that the scattering parameters and noise figure of 10GHZ LNA amplifiers are improved noticeably with respect to the previous works.
International Journal of Innovative Research in Computer and Communication Engineering an Advanced Moving Object Detection Algorithm for Automatic Traffic Monitoring in Real-world Limited Bandwidth Networks

Machine-controlled motion detection technology is Associate in nursing integral element of intelligent transportation systems, and is especially essential for management of traffic and maintenance of traffic police investigation systems. Traffic police investigation systems mistreatment video communication over real-world networks with restricted information measure typically encounter difficulties attributable to network congestion and/or unstable information measure. This is often particularly problematic in wireless video communication. This has necessitated the event of a rate management theme that alters the bit-rate to match the procurable network information measure, thereby manufacturing variable bit-rate video streams. However, complete and correct detection of moving objects beneath variable bit-rate video streams could be a terribly tough task. During this paper, we tend to propose Associate in nursing approach for motion detection that utilizes Associate in nursing analysis-primarily based radial basis perform network as its principal element. This approach is applicable not solely in high bit-rate video streams, however in low bit-rate video streams, as well. The planned approach consists of a varied background generation stage and a moving object detection stage. Throughout the assorted background generation stage, the lower-dimensional Eigen-patterns and also the adjustive background model are established in variable bit-rate video streams by mistreatment the planned approach so as to accommodate the properties of variable bit-rate video streams. Throughout the moving object detection stage, moving objects are extracted via the planned approach in each low bit-rate and high bit-rate video streams; detection results are then generated through the output worth of the planned approach. The detection results created through our approach indicate it to be extremely effective in variable bit-rate video streams over real-world restricted information measure networks. Additionally, the planned methodology will be simply achieved for period of time application. Quantitative and qualitative evaluations demonstrate that it offers blessings over different state-of-the-art ways. For example, and accuracy rates created via the planned approach were up to eighty six.38% and 89.88% beyond those created via different compared ways.
Inferring Social Network Structure using Mobile Phone Data

We analyze 330,000 hours of continuous behavioral data logged by the mobile phones of 94 subjects, and compare these observations with selfreport relational data. The information from these two data sources is overlapping but distinct, and the accuracy of self-report data is considerably affected by such factors as the recency and salience of particular interactions. We present a new method for precise measurements of large-scale human behavior based on contextualized proximity and communication data alone, and identify characteristic behavioral signatures of relationships that allowed us to accurately predict 95% of the reciprocated friendships in the study. Using these behavioral signatures we can predict, in turn, individual-level outcomes such as job satisfaction.
Contextual Modulation in Primary Visual Cortex

We studied extra-receptive field contextual modulation in area V1 of awake, behaving macaque monkeys. Contextual modulation was studied using texture displays in which texture covering the receptive field (RF) was the same in all trials, but the perceptual context of this texture could vary depending on the configuration of extra-RF texture elements. We found robust contextual modulation when disparity, color, luminance, and orientation cues variously defined a textured figure centered on the RF of V1 neurons. We found contextual modulation to have a spatial extent of ∼8 to 10° diameter parafoveally. Contextual modulation correlated with perceptual experience of both binocularly rivalrous texture displays and of displays with a simple example of surface occlusion. We found contextual modulation in V1 to have a characteristic latency of 80–100 msec after stimulus onset, potentially allowing feedback from extrastriate areas to underlie to this effect.
Does Parental Mediation of Media Influence Child Outcomes? A Meta-Analysis on Media Time, Content, Aggression, Substance Use, Sexual Behavior, and Health Outcomes

Does Parental Mediation of Media Influence Child Outcomes? A Meta-Analysis on Media Time, Content, Aggression, Substance Use, Sexual Behavior, and Health Outcomes Kevin Matthew Collier School of Family Life, BYU Master of Science As the world evolves into a media saturated environment, the focus of many studies have been the negative effects of media on children and adolescents. For at least the past two decades, researchers have explored how parental involvement in their child’s media consumption can influence child outcomes. Parental mediation of media includes restrictive mediation, active mediation, and co-viewing. Three meta-analyses, one for each type of mediation, reviewed a total of 69 studies. Each analysis assessed the effectiveness of parental mediation of media on five pertinent child outcomes: media use, aggression, substance use, sexual behavior, and negative health outcomes. The overall results indicated small, but significant relationships between child outcomes and restrictive mediation (r+ = .07), active mediation (r+ = .01), and coviewing (r+ = .09). Effects on certain child outcomes were stronger than others. Parents have the ability to mitigate some of the adverse effects through parental mediation of media by creating rules for media use; discussing character’s choices and central themes; and consuming media together. Finally, several gaps in the existing literature were identified and discussed.
Increased Fidelity Reduces Poliovirus Fitness and Virulence under Selective Pressure in Mice

RNA viruses have high error rates, and the resulting quasispecies may aid survival of the virus population in the presence of selective pressure. Therefore, it has been theorized that RNA viruses require high error rates for survival, and that a virus with high fidelity would be less able to cope in complex environments. We previously isolated and characterized poliovirus with a mutation in the viral polymerase, 3D-G64S, which confers resistance to mutagenic nucleotide analogs via increased fidelity. The 3D-G64S virus was less pathogenic than wild-type virus in poliovirus-receptor transgenic mice, even though only slight growth defects were observed in tissue culture. To determine whether the high-fidelity phenotype of the 3D-G64S virus could decrease its fitness under a defined selective pressure, we compared growth of the 3D-G64S virus and 3D wild-type virus in the context of a revertible attenuating point mutation, 2C-F28S. Even with a 10-fold input advantage, the 3D-G64S virus was unable to compete with 3D wild-type virus in the context of the revertible attenuating mutation; however, in the context of a non-revertible version of the 2C-F28S attenuating mutation, 3D-G64S virus matched the replication of 3D wild-type virus. Therefore, the 3D-G64S high-fidelity phenotype reduced viral fitness under a defined selective pressure, making it likely that the reduced spread in murine tissue could be caused by the increased fidelity of the viral polymerase.
Compressive Coded Aperture Keyed Exposure Imaging with Optical Flow Reconstruction

This paper describes a coded aperture and keyed exposure approach to compressive video measurement which admits a small physical platform, high photon efficiency, high temporal resolution, and fast reconstruction algorithms. The proposed projections satisfy the Restricted Isometry Property (RIP), and hence compressed sensing theory provides theoretical guarantees on the video reconstruction quality. Moreover, the projections can be easily implemented using existing optical elements such as spatial light modulators (SLMs). We extend these coded mask designs to novel dual-scale masks (DSMs) which enable the recovery of a coarse-resolution estimate of the scene with negligible computational cost. We develop fast numerical algorithms which utilize both temporal correlations and optical flow in the video sequence as well as the innovative structure of the projections. Our numerical experiments demonstrate the efficacy of the proposed approach on short-wave infrared data.
Human cortical auditory motion areas are not motion selective

The existence of a specialized mechanism supporting auditory motion processing in humans is a matter of debate in the psychophysical literature. Recent functional neuroimaging data appear to have resolved the debate in favor of a specialized motion system in that several studies have found cortical regions that seem to be motion selective. While all these studies contrast some form of moving auditory stimulation with a stationary stimulus, none have adequately controlled for the possibility that these areas are simply computing sound-source location and not motion per se: a moving stimulus varies in spatial location as well as motion, and so a system computing spatial location (and not motion) would be activated in response to both a moving and stationary sound source. To control for this possibility, ten subjects were scanned while listening to moving stimuli and while listening to stationary stimuli that varied randomly in spatial location. Consistent with previous imaging studies, we found that a motion stimulus when contrasted with rest (scanner noise) activated STG/planum temporale (bilaterally) and right parietal lobe. However, stationary stimuli presented at varying locations activated these regions equally well, arguing against the existence of specialized motion-processing areas in human cortex.
El estudio de las fortalezas del carácter en niños: Relaciones con el bienestar psicológico, la deseabilidad social y la personalidad

Este trabajo tuvo como objetivo corroborar la existencia de asociaciones entre las fortalezas del caracter, el bienestar psicologico, la deseabilidad social y la personalidad en ninos de 10 a 12 anos. Participaron de este estudio 518 ninos (254 varones y 263 mujeres) que tenian entre 10 y 12 anos y que asistian a escuelas publicas y privadas de la Ciudad de Buenos Aires (Argentina). Se administraron: una encuesta sociodemografica, una encuesta para evaluar los cinco elementos de la teoria PERMA de acceso al bienestar, el Inventario de Virtudes y Fortalezas para Ninos, el Cuestionario de Personalidad Infantil y la Escala de Deseabilidad Social Infantil. Los resultados mostraron que, al igual que en estudios previos, la vitalidad, la esperanza y la curiosidad fueron las fortalezas que mas se asociaron con la satisfaccion vital. A su vez, se encontraron correlaciones estadisticamente significativas entre los cinco elementos de la teoria PERMA de acceso al bienestar (Seligman, 2011) y la mayoria de las fortalezas del caracter. Por su parte, las fortalezas tambien se encontraron asociadas al modelo de los Cinco Grandes Factores de la Personalidad y la deseabilidad social. Finalmente, se hallaron diferencias en la presencia de las fortalezas del caracter de acuerdo al sexo y la edad.
