BLUE STRAGGLERS AFTER THE MAIN SEQUENCE

We study the post-main-sequence evolution of products of collisions between main-sequence stars (blue stragglers), with particular interest paid to the horizontal branch and asymptotic giant branch phases. We found that the blue straggler progeny populate the color-magnitude diagram slightly blueward of the red giant branch and between 0.2 and 1 magnitudes brighter than the horizontal branch. We also found that the lifetimes of collision products on the horizontal branch is consistent with the numbers of so-called “evolved blue straggler stars” (E-BSS) identified by various authors in a number of globular clusters, and is almost independent of mass or initial composition profile. The observed ratio of the number of E-BSS to blue stragglers points to a main-sequence lifetime for blue stragglers of approximately 1–2 Gyr on average.
Single transistor primitive for timing and power modelling of CMOS gates

An accurate and efficient method for modelling CMOS gates by a single equivalent transistor is introduced in this paper. The output waveform of a CMOS inverter is obtained by solving the circuit differential equation considering only the conducting transistor of the inverter. The effect of the short-circuiting transistor is incorporated as a differentiation of the width of the conducting transistor. The proposed model is the simplest primitive that can be used in order to obtain the propagation delay and short-circuit power dissipation of CMOS gates. Consequently, it can offer significant speed improvement to existing dynamic timing and power simulators while maintaining a sufficient level of accuracy.
Anomaly Recognition in Online Social Networks

The popularity of social networking sites has increased throughout the decade and everything that gains immense popularity with great human involvement also brings many challenges and issues along with it. Similarly the excessive use of online social networking causes a great increase in anomalies. In social networking the anomalies are like fake account, account hack, identity theft, spams and many other illegitimate activities. It is thus necessary to detect such anomalous and suspicious behavior of any user at these social platforms, as they could have an adverse impact on users, especially on teenagers. In this paper, we propose various methodologies for early detection of suspicious and anomalous activities. We have done the analysis of various parameters of social networking and its graph like indegree, outdegree, active time of a node (user) and its behavior.
Multi-focus image fusion using epifluorescence microscopy for robust vascular segmentation

Automatic segmentation of three-dimensional mi-crovascular structures is needed for quantifying morphological changes to blood vessels during development, disease and treatment processes. Single focus two-dimensional epifluorescent imagery lead to unsatisfactory segmentations due to multiple out of focus vessel regions that have blurred edge structures and lack of detail. Additional segmentation challenges include varying contrast levels due to diffusivity of the lectin stain, leakage out of vessels and fine morphological vessel structure. We propose an approach for vessel segmentation that combines multi-focus image fusion with robust adaptive filtering. The robust adaptive filtering scheme handles noise without destroying small structures, while multi-focus image fusion considerably improves segmentation quality by deblurring out-of-focus regions through incorporating 3D structure information from multiple focus steps. Experiments using epifluorescence images of mice dura mater show an average of 30.4% improvement compared to single focus microvasculature segmentation.
The Other Side: Occupational Interactional Requirements and Work-Home Enrichment

We examine how occupational interactional requirements influence work–home enrichment. We conceptualize “occupational interactional requirements” as restorative properties of jobs that provide employees with resources that they transfer to the home domain. We identify two manifestations of work–home enrichment: (1) through objective indicators of how employees allocate their time at home, and (2) through employees’ perceptual reflections of their work–home enrichment. In terms of objective indicators, our results indicate that employees transfer these resources by spending more time in resource-draining activities such as caring for family, and less time in resource-replenishing activities such as socializing and relaxing. This suggests that occupational interactional requirements facilitate a reallocation of time in the home domain. In terms of perceptual reflections, we observe that occupational interactional requirements spark employees’ vitality, which, in turn, enriches their life at home. Our result.
Unlearning the Traditional File Systems Model , Applying Peer to Peer Techniques for Information Management

Distributed File Systems since the very early days have been thought of and developed on the lines of a “strict” Client–Server architecture. This is the thing Sturgis et al.[1] refer to in their paper as an “independent file facility”. This facility was always visualized as an extension to the traditional (nondistributed or local) filesystem and consequently was applied the same design model. This paper tries to explore the possibilities of augmenting the distributed file systems design model, with the features of the Peer to Peer file sharing system. An analogy can be drawn to the method of solving a maze by starting at the desired exit and tracing the path towards the subject. We take a look at the various Peer to Peer systems in use now, their structure (or the lack of one), their strong and weak points. Next we compare various P2P architectures, and some implementations based on each of them. Although we will try and explore the weak and strong points of each relevant in this case an in depth discussion is avoided and the interested reader can find the respective papers in the references. There are some examples of P2P based file systems which have been proposed and implemented, quite a few of them based on the Chord distributed lookup system[2] (using the Distributed Hash Tables). We explain the system in brief and judge the suitability of the proposed mechanism for P2P systems. Finally we explore the Prospero Resource Manager interface, for its suitability to this case.

Shaping prestimulus neural activity with auditory rhythmic stimulation improves the temporal allocation of attention

Human attention fluctuates across time, and even when stimuli have identical physical characteristics and the task demands are the same, relevant information is sometimes consciously perceived and at other times not. A typical example of this phenomenon is the attentional blink, where participants show a robust deficit in reporting the second of two targets (T2) in a rapid serial visual presentation (RSVP) stream. Previous electroencephalographical (EEG) studies showed that neural correlates of correct T2 report are not limited to the RSVP period, but extend before visual stimulation begins. In particular, reduced oscillatory neural activity in the alpha band (8-12 Hz) before the onset of the RSVP has been linked to lower T2 accuracy. We therefore examined whether auditory rhythmic stimuli presented at a rate of 10 Hz (within the alpha band) could increase oscillatory alpha-band activity and improve T2 performance in the attentional blink time window. Behaviourally, the auditory rhythmic stimulation worked to enhance T2 accuracy. This enhanced perception was associated with increases in the posterior T2-evoked N2 component of the event-related potentials and this effect was observed selectively at lag 3. Frontal and posterior oscillatory alpha-band activity was also enhanced during auditory stimulation in the pre-RSVP period and positively correlated with T2 accuracy. These findings suggest that ongoing fluctuations can be shaped by sensorial events to improve the allocation of attention in time.
Spatial Augmented Reality for Interactive Rapid Prototyping

This paper investigates the use of Spatial Augmented Reality for industrial design. We have implemented a prototyping system that augments low fidelity physical models with projected images. These enhanced prototypes are used to create and evaluate the design of a product. The traditional method of interactive prototyping involves building a physical model of the device with working components such as buttons. Virtual versions of these components are directly projected onto the low fidelity prototype with Spatial Augmented Reality. The user’s fingers are tracked to allow interactive SAR buttons to be fully functional. This enables the user to manipulate the virtual components in real-time, saving the time and cost of manually installing them. We discuss our implementation of this prototyping system and how it integrates with the design process. In addition, we have evaluated our method of interacting with Spatial Augmented Reality prototypes. The results indicate that users can interact naturally with projected control panels, and that the system provides a useful tool for designers.
Tianeptine: clinical properties

Summary Tianeptine has been shown to be an effective antidepressant versus reference drugs and to be better tolerated than amitriptyline, without the latter's anticholinergic side-effects. Its good acceptability has been confirmed in long-term use (1 year) in large patient groups. In an open pilot trial in endogenous melancholia, tianeptine showed the same activity as would be expected of a conventional antidepressant. This is being verified in a double-blind trial versus maprotiline. In a separate open study, it has demonstrated a potential to prevent relapse and recurrence in depressed patients treated for 1 year. These results are currently being tested versus placebo.
What is the Affect by Leader Emotion in an Organization? Exploring the Effects of Leader Emotion on Leader Role and Employee Impression

Because communication media is existence that leads to public figures change public affairs get easier via their speech statement or article. Above lures makes this work considers character of the leader would significant influence to whole enterprise operation. Therefore this work supposes leader emotion maybe positive emotion or negative emotion would affect the relationship between leader role and employee impression. According to the result of statistical analysis reveals emotion that involve with positive emotion and negative emotion of leader is moderator to influence the relationship between leader role and employee impression. If a company would like to create a designate employee impression style could be focus on leader character also employee impression built upon the leader emotion. Thus this work explains rank- and-file employees impression created will be different in positive leader emotion or negative leader emotion. Emotion of leader would deep and far affect a company through employees indirectly.
Identification of Repellent and Insecticidal Constituents of the Essential Oil of Artemisia rupestris L. Aerial Parts against Liposcelis bostrychophila Badonnel

The aim of this research was to determine the chemical composition and insecticidal and repellent activity of the essential oil of Artemisia rupestris L. aerial parts against the booklice Liposcelis bostrychophila Badonnel and isolation of insecticidal and repellent constituents from the essential oil. The essential oil of A. rupestris was obtained by hydrodistillation and analyzed by GC-MS. A total of 30 components of the essential oil of A. rupestris was identified and the principal compounds in the essential oil were α-terpinyl acetate (37.18%), spathulenol (10.65%), α-terpineol (10.09%), and linalool (7.56%), followed by 4-terpineol (3.92%) and patchoulol (3.05%). Based on bioactivity-guided fractionation, the four active constituents were isolated from the essential oil and identified as α-terpineol, α-terpinyl acetate, 4-terpineol and linalool. The essential oil of A. rupestris exhibited contact toxicity against L. bostrychophila with LD50 value of 414.48 µg/cm2. α-Terpinyl acetate (LD50 = 92.59 µg/cm2) exhibited stronger contact toxicity against booklice than α-terpineol (LD50 = 140.30 µg/cm2), 4-terpineol (LD50 = 211.35 µg/cm2), and linalool (LD50 = 393.16 µg/cm2). The essential oil of A. rupestris (LC50 = 6.67 mg/L air) also possessed fumigant toxicity against L. bostrychophila while the four constituents, 4-terpineol, α-terpineol, α-terpinyl acetate and linalool had LC50 values of 0.34, 1.12, 1.26 and 1.96 mg/L air, respectively. α-Terpinol and α-terpinyl acetate showed strong repellency against L. bostrychophila, while linalool and 4-terpinol exhibited weak repellency. The results indicate that the essential oil of A. rupestris aerial parts and its constituent compounds have potential for development into natural insecticides or fumigants as well as repellents for control of insects in stored grains.
Role of NADH: quinone oxidoreductase-1 in the tight junctions of colonic epithelial cells

NADH:quinone oxidoreductase 1 (NQO1) is known to be involved in the regulation of energy synthesis and metabolism, and the functional studies of NQO1 have largely focused on metabolic disorders. Here, we show for the first time that compared to NQO1-WT mice, NQO1-KO mice exhibited a marked increase of permeability and spontaneous inflammation in the gut. In the DSS-induced colitis model, NQO1-KO mice showed more severe inflammatory responses than NQO1-WT mice. Interestingly, the transcript levels of claudin and occludin, the major tight junction molecules of gut epithelial cells, were significantly decreased in NQO1-KO mice. The colons of NQO1-KO mice also showed high levels of reactive oxygen species (ROS) and histone deacetylase (HDAC) activity, which are known to affect transcriptional regulation. Taken together, these novel findings indicate that NQO1 contributes to the barrier function of gut epithelial cells by regulating the transcription of tight junction molecules.

emoBAN: Improving Quality of Life via Psychophysiological Mobile Computing

Our daily affective states are a key element in the analyse is of our quality of life (QoL). Yet, to date a reliable and accurate solution for an affect analysis in our daily environments does not exist. This paper draws a research path towards a development of a Body Area Network (emoBAN) that enables long-term monitoring and analysis of affective states, as well as provision of appropriate feedback via adaptive interfaces. emoBAN can be realized with the use of unobtrusive psycho physiological measurement sensors (e.g., heart rate, respiration), supported by mobile-device based self-reports to investigate a range of affects we exhibit in our natural daily life environments. The acquired data can be automatically mined for patterns and correlated with different contexts, such that QoL could be quantified and areas of personal improvement pointed out. With the use of emoBAN, we can gain a deeper understanding of our personal experiences and resulting behaviors. The system has the potential to be exploited in many application domains and contribute to defining new research questions in disciplines ranging from behavioral to applied sciences.
Analysis of Composition and Structure of Coastal to Mesopelagic Bacterioplankton Communities in the Northern Gulf of Mexico

16S rRNA gene amplicons were pyrosequenced to assess bacterioplankton community composition, diversity, and phylogenetic community structure for 17 stations in the northern Gulf of Mexico (nGoM) sampled in March 2010. Statistical analyses showed that samples from depths ≤100 m differed distinctly from deeper samples. SAR 11 α-Proteobacteria and Bacteroidetes dominated communities at depths ≤100 m, which were characterized by high α-Proteobacteria/γ-Proteobacteria ratios (α/γ > 1.7). Thaumarchaeota, Firmicutes, and δ-Proteobacteria were relatively abundant in deeper waters, and α/γ ratios were low (<1). Canonical correlation analysis indicated that δ- and γ-Proteobacteria, Thaumarchaeota, and Firmicutes correlated positively with depth; α-Proteobacteria and Bacteroidetes correlated positively with temperature and dissolved oxygen; Actinobacteria, β-Proteobacteria, and Verrucomicrobia correlated positively with a measure of suspended particles. Diversity indices did not vary with depth or other factors, which indicated that richness and evenness elements of bacterioplankton communities might develop independently of nGoM physical-chemical variables. Phylogenetic community structure as measured by the net relatedness (NRI) and nearest taxon (NTI) indices also did not vary with depth. NRI values indicated that most of the communities were comprised of OTUs more distantly related to each other in whole community comparisons than expected by chance. NTI values derived from phylogenetic distances of the closest neighbor for each OTU in a given community indicated that OTUs tended to occur in clusters to a greater extent than expected by chance. This indicates that “habitat filtering” might play an important role in nGoM bacterioplankton species assembly, and that such filtering occurs throughout the water column.
A General Model for the Data Plan of Virtual Router Based on NP

Router virtualization allows multiple virtual router instances to run on the same physical platform. And high performance and flexible deployment are the main challenges for the design of virtual router. In this paper, we firstly analyze, discuss and illustrate the features and limitations of virtual router models that were proposed by many research communities for the support of virtual networks. Then, we put forward a general model for the data plan of virtual router which not only provides a Modules Database that can easily develop virtual routers to fulfill the requirement of service provider, but also has a similar kernel providing a series of standard APIs that can provide a good programming environment for software programmers who even know nothing of the underlying physical platform. Furthermore, we also analyze the challenges encountered and discuss the next works in the future.
Analysis of ADSL traffic on an IP backbone link

Measurements from an Internet backbone link carrying TCP traffic towards different ADSL areas are analyzed. For traffic analysis, we adopt a flow based approach and the popular mice/elephants dichotomy, where mice refer to short traffic transfers and elephants to long transfers. The originality of the reported experimental data, when compared with previous measurements from very high speed backbone links, is that the commercial traffic includes a significant part generated by peer-to-peer applications. This kind of traffic exhibits some remarkable properties in terms of mice and elephants, as we describe. It turns out that by adopting a suitable level of aggregation, the bit rate of mice can be described by means of a Gaussian process. The bit rate of elephants is smoother than that of mice and can also be well approximated by a Gaussian process.
PJAIT systems for the IWSLT 2015 evaluation campaign enhanced by comparable corpora

In this paper, we attempt to improve Statistical Machine Translation (SMT) systems on a very diverse set of language pairs (in both directions): Czech - English, Vietnamese - English, French - English and German - English. To accomplish this, we performed translation model training, created adaptations of training settings for each language pair, and obtained comparable corpora for our SMT systems. Innovative tools and data adaptation techniques were employed. The TED parallel text corpora for the IWSLT 2015 evaluation campaign were used to train language models, and to develop, tune, and test the system. In addition, we prepared Wikipedia-based comparable corpora for use with our SMT system. This data was specified as permissible for the IWSLT 2015 evaluation. We explored the use of domain adaptation techniques, symmetrized word alignment models, the unsupervised transliteration models and the KenLM language modeling tool. To evaluate the effects of different preparations on translation results, we conducted experiments and used the BLEU, NIST and TER metrics. Our results indicate that our approach produced a positive impact on SMT quality.
On Optimal TCM Encoders

An asymptotically optimal trellis-coded modulation (TCM) encoder requires the joint design of the encoder and the binary labeling of the constellation. Since analytical approaches are unknown, the only available solution is to perform an exhaustive search over the encoder and the labeling. For large constellation sizes and/or many encoder states, however, an exhaustive search is unfeasible. Traditional TCM designs overcome this problem by using a labeling that follows the set-partitioning principle and by performing an exhaustive search over the encoders. In this paper we study binary labelings for TCM and show how they can be grouped into classes, which considerably reduces the search space in a joint design. For 8-ary constellations, the number of different binary labelings that must be tested is reduced from 8! =40320 to 240. For the particular case of an 8-ary pulse amplitude modulation constellation, this number is further reduced to 120 and for 8-ary phase shift keying to only 30. An algorithm to generate one labeling in each class is also introduced. Asymptotically optimal TCM encoders are tabulated which are up to 0.3 dB better than the previously best known encoders.
