Modular Generation and Customization

Modularity and flexibility can conflict in multi-language systems. For example, the templates commonly used to generate web pages must be manually updated when the database schema changes. Modularity can be improved by generating web pages automatically from the database schema, but it is hard for such a generator to produce the same variety of outputs that are easily achieved by ad hoc edits to a template. Ideally, such ad hoc edits would be abstracted into transformations that compose with the generator, offering both modularity and flexibility. However common customizations cannot be abstracted using the standard techniques of textual identifiers and ordinal positions. These difficulties are distilled into a challenge problem to evaluate potential solutions. A solution is proposed based on field trees, a new data model for software artifacts that provides persistent identifiers and unshifting positions within sequences. But using field trees with conventional programming languages and development environments requires more effort than the ad hoc editing they seek to supplant. Field trees are therefore extended into differential trees, which integrate artifacts and their transformations into a unified representation.
Context Aware Matrix Factorization for Event Recommendation in Event-Based Social Networks

Event-based Social Networks(EBSNs) which combine online interactions and offline events among users have experienced increased popularity and rapid growth recently. In EBSNs, event recommendation is significant for users due to the extremely large amount of events. However, the event recommendation problem is rather challenging because it faces a serious cold-start problem: Events have short life time and new events are registered by only a few users. What's more, there are only implicit feedback information. Existing approaches like collaborative filtering methods are not suitable for this scenario. In this paper, we propose a Context Aware Matrix Factorization model called AlphaMF to tackle with the problem. Specifically, AlphaMF is a unified model that combines the Matrix Factorization model which models implicit feedbacks with the Linear contextual features model which models explicit contextual features. Extensive experiments on a large real-world EBSN dataset demonstrate that the AlphaMF model significantly outperforms state-of-the-art methods by 11%.
Elevated striatal dopamine function linked to prodromal signs of schizophrenia.

CONTEXT A major limitation on the development of biomarkers and novel interventions for schizophrenia is that its pathogenesis is unknown. Although elevated striatal dopamine activity is thought to be fundamental to schizophrenia, it is unclear when this neurochemical abnormality develops in relation to the onset of illness and how this relates to the symptoms and neurocognitive impairment seen in individuals with prodromal symptoms of schizophrenia. OBJECTIVES To determine whether striatal dopamine function is elevated in individuals with prodromal symptoms of schizophrenia before the onset of psychosis and to assess how this relates to the symptoms and neurocognitive impairment. DESIGN Case-control study of in vivo striatal dopaminergic function. SETTING Academic research. Patients Patients were recruited from a community mental health service. Twenty-four patients having prodromal symptoms of schizophrenia were compared with 7 patients having schizophrenia and with 12 matched healthy control subjects from the same community. Main Outcome Measure Striatal 6-fluoro-l-dopa F 18-dopa uptake measured using positron emission tomographic (18)F-dopa imaging. RESULTS Striatal (18)F-dopa uptake was elevated in patients with prodromal symptoms of schizophrenia (effect size, 0.75) to an intermediate degree compared with that in patients with schizophrenia (effect size, 1.25). The elevation was localized in the associative striatum in both groups. Moreover, striatal (18)F-dopa uptake in patients with prodromal symptoms of schizophrenia was correlated with the severity of prodromal psychopathologic and neuropsychological impairment but not with the severity of anxiety or depressive symptoms. CONCLUSIONS These findings indicate that dopamine overactivity predates the onset of schizophrenia in individuals with prodromal psychotic symptoms, is predominantly localized in the associative striatum, and is correlated with the severity of symptoms and neurocognitive dysfunction.
Priming and Media Impact on the Evaluations of the President's Performance

The period between August 1990 and early November 1992 was characterized by two “issue regimes,” the Gulf War and an economic recession. Analysis of aggregate media content and opinion poll data shows that President George Bush's job approval ratings were closely tied to the changes in the salience of these two issues. Guided by priming theory, hypotheses were formulated and tested concerning media effects on voters' evaluations of President Bush. Results show that the pattern of forming Bush's approval ratings is related to two different issue regimes. The total dominance of the public arena by one issue during an issue regime sets the foundation of Bush's overall approval ratings. However, direct media priming effects are found limited. Implications of these results are discussed.
The Influence on Behaviors of Teachers Using the Interactive Electronic Whiteboard for Teaching at Primary Schools

In recent years, the Ministry of Education in Taiwan promoting e-classroom primary schools have also contributed to the purchase of interactive electronic whiteboards for teaching. However, compared to the traditional blackboard teaching the researchers tried to explore the issues whether whiteboard can enhance the effectiveness of learning and whether teachers using whiteboards will cause inconvenience of teaching which led to decline in the effectiveness of learning. Therefore, this study by using UTAUT model for the foundation hopes to explore the status of teachers in the whiteboard teaching and whether it has a positive impact on their intension to use. According to the analysis results of SEM-PLS, this study discusses patterns for the whole meaning of the practice and further proposes for advice on teaching practice and also through the results in order to improve the overall intension to use whiteboards for teaching.
The predictors of parasocial interaction and their effects on perceived persuasiveness

OF THE THESIS The Predictors of Parasocial Interaction and Their Effects on Perceived Persuasiveness by Renee E. Rumpf Master of Arts in Communication San Diego State University, 2012 Past research on parasocial interaction has identified a number of user and media figure characteristics that increase the level of parasocial interaction between the individual and media figure. Additionally, research shows that media figures are found to be persuasive to media users and consumers. Research has yet to address the influence of media user characteristics on engagement with PSI. This paper uses a uses and gratifications framework to identify hypotheses regarding personal characteristics of self-esteem, attachment needs, relationship status and media figure characteristics of attractiveness, homophily, and fictionality and how they relate to PSI. To test these hypotheses, an online study was conducted to measure the user characteristics of self-esteem, attachment needs, and relationship status and the media figure characteristics of perceived attractiveness, perceived homophily, and whether they are real or fictional and test the association of user and media figure characteristics with the level of PSI. The relationship between PSI and persuasion was also tested. A research question of whether more real or fictional characters was also included to provide insight in to an area that previously has not been researched. Linear regression analysis indicated that PSI was not related to the characteristics of the media user (self-esteem, attachment needs, and relationship status), but was related to characteristics of the media figure (attractiveness, homophily and realness). The frequency was run on the variable of real versus fictional and found that 74.4% provided the name of a real media figure. As expected, PSI was also related to persuasion. The findings of this study have implications in many media-related fields, as we see that characteristics of the media figure are more predictive of PSI and thus persuasion.
Bandgap scaling in bilayer graphene antidot lattices

On the basis of a tight binding model we reveal how the bandgap in bilayer graphene antidot lattices (GALs) follows a different scaling law than in monolayer GALs and we provide an explanation using the Dirac model. We show that previous findings regarding the criteria for the appearance of a bandgap in monolayer GALs are equally applicable to the bilayer case. Furthermore, we briefly investigate the optical properties of bilayer GALs and show that estimates of the bandgap using optical methods could lead to overestimates due to weak oscillator strength of the lowest transitions. Finally, we investigate the effect of imposing an electric field perpendicular to the bilayer GAL structure and find that the bandgap tunability may be extended as compared to pristine bilayer graphene.
Enhanced ADCC Activity of Affinity Maturated and Fc-Engineered Mini-Antibodies Directed against the AML Stem Cell Antigen CD96

CD96, a cell surface antigen recently described to be preferentially expressed on acute myeloid leukemia (AML) leukemic stem cells (LSC) may represent an interesting target structure for the development of antibody-based therapeutic approaches. The v-regions from the CD96-specific hybridoma TH-111 were isolated and used to generate a CD96-specific single chain fragment of the variable regions (scFv). An affinity maturated variant resulting in 4-fold enhanced CD96-binding was generated by random mutagenesis and stringent selection using phage display. The affinity maturated scFv CD96-S32F was used to generate bivalent mini-antibodies by genetically fusing an IgG1 wild type Fc region or a variant with enhanced CD16a binding. Antibody dependent cell-mediated cytotoxicity (ADCC) experiments revealed that Fc engineering was essential to trigger significant effector cell-mediated lysis when the wild type scFv was used. The mini-antibody variant generated by fusing the affinity-maturated scFv with the optimized Fc variant demonstrated the highest ADCC activity (2.3-fold enhancement in efficacy). In conclusion, our data provide proof of concept that CD96 could serve as a target structure for effector cell-mediated lysis and demonstrate that both enhancing affinity for CD96 and for CD16a resulted in mini-antibodies with the highest cytolytic potential.
Detection, Characterization and Evolution of Internal Repeats in Chitinases of Known 3-D Structure

Chitinase proteins have evolved and diversified almost in all organisms ranging from prokaryotes to eukaryotes. During evolution, internal repeats may appear in amino acid sequences of proteins which alter the structural and functional features. Here we deciphered the internal repeats from Chitinase and characterized the structural similarities between them. Out of 24 diverse Chitinase sequences selected, six sequences (2CJL, 2DSK, 2XVP, 2Z37, 3EBV and 3HBE) did not contain any internal repeats of amino acid sequences. Ten sequences contained repeats of length <50, and the remaining 8 sequences contained repeat length between 50 and 100 residues. Two Chitinase sequences, 1ITX and 3SIM, were found to be structurally similar when analyzed using secondary structure of Chitinase from secondary and 3-Dimensional structure database of Protein Data Bank. Internal repeats of 3N17 and 1O6I were also involved in the ligand-binding site of those Chitinase proteins, respectively. Our analyses enhance our understanding towards the identification of structural characteristics of internal repeats in Chitinase proteins.
Velocity Invariance of Receptive Field Structure in Somatosensory Cortical Area 3b of the Alert Monkey

This is the second in a series of studies of the neural representation of tactile spatial form in cortical area 3b of the alert monkey. We previously studied the spatial structure of 330 area 3b neuronal receptive fields (RFs) on the fingerpad with random dot patterns scanned at one velocity (40 mm/sec; DiCarlo et al., 1998). Here, we analyze the temporal structure of 84 neuronal RFs by studying their spatial structure at three scanning velocities (20, 40, and 80 mm/sec). As in the previous study, most RFs contained a single, central, excitatory region and one or more surrounding or flanking inhibitory regions. The mean time delay between skin stimulation and its excitatory effect was 15.5 msec. Except for differences in mean rate, each neuron’s response and the spatial structure of its RF were essentially unaffected by scanning velocity. This is the expected outcome when excitatory and inhibitory effects are brief and synchronous. However, that interpretation is consistent neither with the reported timing of excitation and inhibition in somatosensory cortex nor with the third study in this series, which investigates the effect of scanning direction and shows that one component of inhibition lags behind excitation. We reconcile these observations by showing that overlapping (in-field) inhibition delayed relative to excitation can produce RF spatial structure that is unaffected by changes in scanning velocity. Regardless of the mechanisms, the velocity invariance of area 3b RF structure is consistent with the velocity invariance of tactile spatial perception (e.g., roughness estimation and form recognition).
Effects of Learning by Video Modeling on Gymnastic Performances among Tunisian Students in the Second Year of Secondary Level

The purpose of this work was to analyze the effects of learning through video modeling combined of sessions of physical education on gymnastic performance among Tunisian students in the second year of secondary level. Our study was conducted on a sample of 103 subjects (16,95 0,9 years) divided into two independent groups (experimental and control). The experimental group was subjected to a cycle of video modeling with explanations and verbal representations of gymnastic skills combined with sessions of physical education gymnastics, while the second group was practiced gymnastics with the usual conditions in the physical education sessions. Measures of performances were taken before and after the experiment. These results demonstrate the effectiveness of learning by video modeling procedures for the acquisition and improvement of gymnastic skills for students. In addition, the progression of gymnastic performance of girls is more important than boys after receiving the learning by video modeling.
A Novel Peritoneum Derived Vascular Prosthesis Formed on a Latex Catheter in an SDF-1 Chemokine Enriched Environment: A Pilot Study

Introduction Although saphenous vein grafts are widely used conduits for coronary artery bypass graft surgery, their clinical value remains limited due to high failure rates. The aim of the study was to evaluate feasibility, safety, and biocompatibility of peritoneal derived vascular grafts (PDVG) formed on a silicone-coated, latex, Foley catheter in a stromal cell-derived factor (SDF-1)- enriched environment. Methods Foley catheters were implanted into the parietal wall of 8 sheep. After 21 days the peritoneal cavity was re-opened and the newly formed tissue fragments were harvested. The animals were randomly assigned into: (1) study group in which conduits were incubated in a solution containing SDF-1, (2) control group without SDF-1 incubation. Left carotid arteries were accessed and “end-to-side” anastomoses were performed. Biological materials for histological examination were taken at 4, 7, 10, and 14 days. Results and Conclusions The study proved safety, feasibility, and biocompatibility of PDVG formed on the basis of a silicone-coated, latex catheter in an SDF-1 chemokine-enriched environment. These biological grafts effectively integrated with the native high-pressure arterial environment in an ovine model and provided favorable vascular profile. The potential clinical value of this technology needs to be further elucidated in long-term preclinical and clinical studies.
Training Content and Potential Impact on Performance

The purpose of the present investigation was to compare the content of 8 weeks of training in young endurance-trained male and female runners and study the potential impact of this training content on performance. Fourteen men and 11 women performed two criterion exercises until exhaustion on an outdoor track before and after the 8-week training period. The first test was a graded exercise to determine maximal aerobic velocity (Mav), the velocity at the lactate concentration threshold (v-Tlac), and the velocity at delta 50 (vΔ50: the velocity halfway between Mav and v-Tlac). The second test was a constant run at vΔ50 to determine the time to exhaustion at this velocity (tlimvΔ50). Training logs were used to monitor the self-directed training sessions. The results showed that the women had a lower training volume but trained at higher exercise velocities than the men. However, they presented similar values as the men for expected temporary performance capacity and did not improve their performance (Mav and tlimvΔ50) over the 8-week period. After the training period, only v-Tlac (absolute and relative values) was slightly but significantly increased by training. These results could be due to the fact that both men and women did not train more than 10% of the total distance run at exercise velocities equal to or higher than their Mav and did not increase their training load during the 8-week training period. We suggest that changes in training content during the season, such as severe (long-duration or high-intensity) training sessions, may have improved their performance capacity.

A novel approach for internet traffic classification based on multi-objective evolutionary fuzzy classifiers

Internet traffic classification has moved in the last years from traditional port and payload-based approaches towards methods employing statistical measurements and machine learning techniques. Despite the success achieved by these techniques, they are not able to explain the relation between the features, which describe the traffic flow, and the corresponding traffic classes. This relation can be extremely useful to network managers for quickly handling possible network drawback. In this paper, we propose to tackle the traffic classification problem by using multi-objective evolutionary fuzzy classifiers (MOEFCs). MOEFCs are characterised by good trade-offs between accuracy and interpretability. We adopt two Internet traffic datasets extracted from two real-world networks. We discuss the results obtained both by applying a cross validation on each single dataset, and by using a dataset as training set and the other as test set. We show that, in both cases, MOEFCs can achieve satisfactory accuracy in the face of low complexity and, therefore, high interpretability.
Seasonal shifts of group A rotavirus strains as a possible mechanism of persistence in the human population

This article demonstrates how the seasonal predominance of a new rotavirus strain in Asuncion, Paraguay is correlated with a wide spectrum of age groups of children infected in that given season. Therefore, this study provides new evidence to support the idea that seasonal shift of rotavirus strains is a possible mechanism used by the virus to evade herd immunity (acquired by the population due to previous infections) and, thus, ultimately persist in that population.

A Single–Chip 10-Band WCDMA/HSDPA 4-Band GSM/EDGE SAW-less CMOS Receiver With DigRF 3G Interface and  ${+}$90 dBm IIP2

This paper describes the design and performance of a 90 nm CMOS SAW-less receiver with DigRF interface that supports 10 WCDMA bands (I, II, III, IV, V, VI, VIII, IX, X, XI) and 4 GSM bands (GSM850, EGSM900, DCS1800, PCS1900). The receiver is part of a single-chip SAW-less transceiver reference platform IC for mass-market smartphones, which has been designed to meet Category 10 HSDPA (High Speed Downlink Packet Access) requirements. The novel receiver core consists of a single-stage transconductance amplifier (TCA) with large gain control range, a current commutating passive mixer enhanced for automatic on chip IIP2 calibration with 25% duty-cycle LO injection and threshold adjust, and current-input complex Direct Coupled Filter (DCF). The low noise TCAs are designed without inductive loads to save area. A self-contained on chip automatic IIP2 calibration system with algorithm routine, implemented in firmware, is used to optimize IIP2 performance. This topology eliminates the external LNA, inter-stage SAW filter and transimpedance amplifier (TZA) in conventional WCDMA designs and results in current drain and die area savings as well as improved noise. The 25% duty-cycle LO injection, with threshold adjustment, into a current driven passive double-balanced mixer results in 3 dB additional gain, lower noise figure and lower intermodulation distortion. Large signal blocking and 1/f noise performance are improved significantly by eliminating the 0 and 180deg LO signal crossover at the mixer. The full receiver achieves 2.2 dB/2.39 dB simplex/duplex NF (with - 24.5 dBm TX leakage), > 90 dBm complex two-tone IIP2, 60 dB gain and - 1/+ 5 dBm half/full-duplex image IIP3. The receiver core consumes only 15.1 mA from a 1.5 V supply.
Decoding cognitive brain states

The last years have seen a rise in interest in using BCI methodology for investigating non-medical questions beyond the purpose of communication and control. This abstract first provides a short introduction to BCI challenges from a machine learning perspective. The remaining sections present selected applications of BCI discussing in particular the use of EEG in combination with BCI methods for investigating how signal quality is processed on a sensory and cognitive level.
The telomere system of the Streptomyces linear plasmid SCP1 represents a novel class

Linear plasmids and chromosomes of Streptomyces carry terminal proteins (TPs) covalently attached to the 5′ ends of the DNA. Most known telomeres are conserved in primary sequence and in the potential secondary structures formed during replication. The TP that caps these telomeres is also highly conserved and its coding gene, tpg, is present in all Streptomyces chromosomes and some linear plasmids. Linear plasmid SCP1 contains atypical telomere sequences and no tpg homologue, and can replicate in the absence of tpg, suggesting that it carries a novel TP gene. To isolate the TP on the SCP1 telomeres, we constructed a multicopy mini‐SCP1 plasmid. The TP capping the plasmid was isolated and subjected to tryptic digestion and mass spectrometric analysis, and the results indicated that the TP was encoded by an open reading frame (ORF), SCP1.127 (tpc), on SCP1. Of the two ORFs upstream of tpc, SCP1.125 (tac) but not SCP1.126 was essential for replication of mini‐SCP1. The Tac–Tpc system of SCP1 represents a convergently evolved novel telomere‐capping system of Streptomyces linear replicons.
