Critical exponents predicted by grouping of Feynman diagrams in φ4 model

Different perturbation theory treatments of the Ginzburg‐Landau phase transition model are discussed. This includes a criticism of the perturbative renormalization group (RG) approach and a proposal of a novel method providing critical exponents consistent with the known exact solutions in two dimensions. The usual perturbation theory is reorganized by appropriate grouping of Feynman diagrams of φ4 model with O(n) symmetry. As a result, equations for calculation of the two‐point correlation function are obtained which allow to predict possible exact values of critical exponents in two and three dimensions by proving relevant scaling properties of the asymptotic solution at (and near) the criticality. The new values of critical exponents are discussed and compared to the results of numerical simulations and experiments.
DC motor fault diagnosis by means of artificial neural networks

The paper deals with a model-based fault diagnosis for a DC motor realized using artificial neural networks. The considered process was modelled by using a neural network composed of dynamic neuron models. Decision making about possible faults was performed using statistical analysis of a residual. A neural network was applied to density shaping of a residual, and after that, assuming a significance level, a threshold was calculated. Moreover, to isolate faults a neural classifier was developed. The proposed approach was tested in a DC motor laboratory system at the nominal operating conditions as well as in the case of faults.
α-bisabolol Is an Effective Proapoptotic Agent against BCR-ABL+ Cells in Synergism with Imatinib and Nilotinib

We showed that α-bisabolol is active against primary acute leukemia cells, including BCR-ABL+ acute lymphoblastic leukemias (ALL). Here we studied the activity of α-bisabolol against BCR-ABL+ cells using 3 cell lines (K562, LAMA-84, CML-T1) and 10 primary BCR-ABL+ ALL samples. We found that: (a) α-bisabolol was effective in reducing BCR-ABL+ cell viabilty at concentrations ranging from 53 to 73 µM; (b) α-bisabolol concentrations in BCR-ABL+ cellular compartments were 4- to 12-fold higher than in normal cells, thus indicating a preferential intake in neoplastic cells; (c) α-bisabolol displayed a slight to strong synergism with the Tyrosine Kinase Inhibitors (TKI) imatinib and nilotinib: the combination of α-bisabolol+imatinib allowed a dose reduction of each compound up to 7.2 and 9.4-fold respectively, while the combination of α-bisabolol+nilotinib up to 6.7 and 5-fold respectively; (d) α-bisabolol-induced apoptosis was associated with loss of plasma membrane integrity, irreversible opening of mitochondrial transition pore, disruption of mitochondrial potential, inhibition of oxygen consumption and increase of intracellular reactive oxygen species. These data indicate α-bisabolol as a candidate for treatment of BCR-ABL+ leukemias to overcome resistance to TKI alone and to target leukemic cells through BCR-ABL-independent pathways.
Mother-adolescent agreement regarding decision-making autonomy: a longitudinal comparison of families of adolescents with and without spina bifida.

OBJECTIVE Longitudinal comparison of mother and adolescent agreement regarding decision-making autonomy for adolescents with and without spina bifida (SB). METHODS Forty-two mother-adolescent dyads of adolescents with SB and 55 comparison dyads reported on who was responsible for decision-making across five waves of data collection, beginning at age 8 or 9 years through age 16 or 17 years. RESULTS The proportion of tasks that dyads agreed were decided by adolescents increased over time for both samples beginning at age 12 or 13 years, but appeared to be delayed by roughly two years for youth with SB and was lower for youth with SB from lower socioeconomic (SES) backgrounds. Mothers and adolescents with low SES demonstrated higher proportions of tasks that dyads agreed were decided by mothers. CONCLUSIONS SB and low SES are risk factors for lower levels of agreed-upon decision-making autonomy. Future studies should examine how parent-adolescent agreement regarding autonomy relates to psychosocial outcomes.
On the combination of "off-the-shelf" sentiment analysis methods

Sentiment analysis has become an important topic on the Web, especially in social media, with applications in many domains such as the monitoring of businesses and products as well as the analysis of the repercussion of important events. Several methods and techniques have been independently developed for this purpose in the literature. However, recent work has showed that all of them have varying degrees of coverage and prediction accuracy, with no "silver bullet" for all cases and scenarios. In this paper, we tackle this issue by proposing ensemble combination methods aimed at combining the outputs of several state-of-the-art proposals in order to maximize both goals, which sometimes can be conflicting. We focus on combining "off-the-shelf" methods, increasing enormously the applicability of our strategy. We tested our solutions in a very rich experimentation environment, covering thirteen widely used methods and fourteen labeled datasets from many domains, including messages from social networks, movie and product reviews, opinions and comments in news articles. Our experimental results demonstrate that we can be very successful in our goal, meaning that our proposal can produce a real and important impact in the area of sentiment classification research.
Bisecting or Not Bisecting: This Is the Neglect Question. Line Bisection Performance in the Diagnosis of Neglect in Right Brain-Damaged Patients

In the present study we analysed the bisecting behaviour of 287 chronic right brain-damaged patients by taking into account the presence and severity of extrapersonal and/or personal neglect diagnosed with the hemineglect battery. We also analysed right brain-damaged patients who had (or did not have) neglect according to their line bisection performance. Our results showed that performance of the line bisection task correlates with performance of cancellation tasks, reading and perceptual tasks, but not with the presence of personal neglect. Personal neglect seems to be unrelated to line bisection behaviour. Indeed, patients affected by extrapersonal and personal neglect do not show more severe neglect in line bisection than patients with only extrapersonal neglect. Furthermore, we observed that 20.56% of the patients were considered affected or not by neglect on the line bisection task compared with the other spatial tasks of the hemineglect battery. We conclude that using a battery with multiple tests is the only way to guarantee a reliable diagnosis and effectively plan for rehabilitative training.

Hands on virtual clay

This paper presents a new interaction system designed for hands-on 3D shape modeling and deformation through natural hand gestures. Our system is made of a Phantom haptic device coupled with a deformable foam ball that supports pressure sensors. These sensors detect forces exerted by the user's fingertips, and are used to control the configuration of a compliant virtual hand that is modeling soft virtual clay. During interaction, the user is provided both passive tactile feedback through the foam ball, and realistic visual feedback since the virtual hand deforms due to its interaction in the virtual environment. The combination of all these feedbacks provides the artist with a good immersion allowing for effective sculpting in a virtual world.
Long-term Virologic Suppression Despite Presence of Resistance-associated Mutations Among Perinatally HIV-infected Youth

Background: There is limited information on long-term consequences of continuing combination antiretroviral therapy (cART) consisting of <3 active drugs in treatment-experienced youth with perinatal HIV (PHIV). This study describes the clinical outcomes of PHIV youth who maintained virologic suppression (VS) for ≥1 year despite receiving cART with <3 active agents. Methods: A retrospective cohort study was conducted to quantify the duration of VS (viral load < 400 copies/mL), and using Cox proportional hazards regression, we identify factors associated with the primary outcome of virologic breakthrough (VB). Results: Thirty-seven patients were included. The median age, baseline CD4 count and HIV RNA viral load were 14 years, 477 cells/mm3 and 2920 copies/mL, respectively. All patients harbored reverse transcriptase, and 57% harbored protease mutations. The median duration of VS was 37 months (interquartile range: 22–66). Fifteen patients (41%) had VB. The median change in CD4 count during VS was +82 cells/mm3 at 12 months. The risk of VB was lower in those who gained ≥50 cells/mm3 by 12 months (unadjusted hazards ratio: 0.271; 95% confidence interval: 0.0825–0.893; P, 0.032); however, this was not significant in the adjusted model. Conclusions: VS was maintained for a median of 3 years without decline in CD4 count. Independent risk factors for VB were not identified; however, there was a trend toward higher risk of VB in those without CD4 gain of ≥50 cells/mm3 by 12 months. Suppressive cART containing <3 active agents could be an option in difficult to manage PHIV youth with close monitoring.
The herpes simplex virus type 1 immediate-early protein ICP0 is necessary for the efficient establishment of latent infection

The immediate-early protein ICP0 of herpes simplex virus type 1 (HSV-1) is not essential for viral replication. However, ICP0 is important for efficient viral replication during the productive infection and for reactivation of latent HSV-1 in vivo. The in vitro model of HSV-1 latency in dorsal root ganglia neurons was used to examine the role of ICP0 in the individual steps that could lead to the appearance of a decreased reactivation phenotype of ICP0 mutant viruses. After establishment of latent infections in the neuronal cultures, induction of reactivation by nerve growth factor (NGF) deprivation resulted in the production of infectious virus with delayed kinetics and a burst size that was significantly decreased for the ICP0 mutants compared with wild-type HSV-1. The efficiency of establishment of latency with the ICP0 mutants was similarly decreased at least 10-fold, as measured by three criteria: (i) the percentage of neurons expressing the major latency-associated transcript during the latent infection, (ii) the amount of viral DNA detected in the neuronal cultures, and (iii) the percentage of neurons expressing ICP4 immunoreactivity after the induction of reactivation. The most striking finding was that ICP0 supplied by an adenovirus vector significantly restored the ability of an ICP0 mutant to establish latency and reactivation. These results strongly indicate a critical role for ICP0 in the establishment of the latent HSV-1 infection in the in vitro neuronal model.
A sky polarization compass in lizards: the central role of the parietal eye

SUMMARY The present study first examined whether ruin lizards Podarcis sicula are able to orientate using the e-vector direction of polarized light. Ruin lizards were trained and tested indoors, inside a hexagonal Morris water maze, positioned under an artificial light source producing plane polarized light with a single e-vector, which provided an axial cue. Lizards were subjected to axial training by positioning two identical goals in contact with the centre of two opposite side walls of the Morris water maze. Goals were invisible because they were placed just beneath the water surface, and water was rendered opaque. The results showed that the directional choices of lizards meeting learning criteria were bimodally distributed along the training axis, and that after 90 deg rotation of the e-vector direction of polarized light the lizards directional choices rotated correspondingly, producing a bimodal distribution which was perpendicular to the training axis. The present results confirm in ruin lizards results previously obtained in other lizard species showing that these reptiles can use the e-vector direction of polarized light in the form of a sky polarization compass. The second step of the study aimed at answering the still open question of whether functioning of a sky polarization compass would be mediated by the lizard parietal eye. To test this, ruin lizards meeting learning criteria were tested inside the Morris water maze under polarized light after their parietal eyes were painted black. Lizards with black-painted parietal eyes were completely disoriented. Thus, the present data show for the first time that the parietal eye plays a central role in mediating the functioning of a putative sky polarization compass of lizards.
A computer-assisted method for training and researching timbre memory and evaluation skills

Timbre is a multidimensional attribute of sound and depends to a large extent on its spectral content. The evaluation and control of timbre is a task commonly performed by sound engineers, loudspeaker designers, and subjects participating in listening tests on the quality of transmitted and reproduced sound. Such listening tasks require specific listening abilities. This dissertation presents a training method that aims at developing memory for timbre, sensitivity to timbre changes, and listening strategies involving disciplined auditory attention and efficiency. The physical timbre space is divided into categories defined by the center frequency of standard octave and third-octave resonances. This simplification of the physical timbre space allows the memorization of a limited set of perceptual timbre categories or references that can be used to evaluate other timbres. The proposed method combines the use of computer software for the presentation and evaluation of exercises and individual tutoring sessions with an instructor. The software monitors the actions of listeners during equalization adjustment tasks and allows data to be collected on the sequence of problem solving operators that are used. Performance indicators can thus be compiled and used for the assessment of skill level achieved by the listeners. A global performance index is proposed. A listening test involving the adjustment of multiple peaks and dips in a sound's spectrum is presented, in which the performance of a group of experienced professionals involved in sound recording and audio post-production was compared with a group of student subjects with comparatively little listening experience but who were trained with the method described in the present work for a period of 6 months. Results indicate that overall the experimental student group outperformed the control group of professionals. Suggestions for further improvement of the training method and performance level assessment are proposed.
Towards the Integration of Value and Coordination Models - Position Paper -

Cross-organizational collaborations have a high complexity. Modelling these collaborations can be done from di®erent perspectives. For example, the value perspective represents expected value exchanges in a collaboration while the coordination perspective represents the order in which these exchanges occur. How to maintain consistency between di®erent models during design time as well as runtime constitutes a chal- lenging topic. De¯ning criteria and de¯nitions re°ecting the relation be- tween these models during the entire life cycle is not straightforward. Di®erent criteria are used for di®erent models since each model captures a speci¯c aspect of the collaboration. In this paper we investigate the challenges arising when addressing the problem of maintaining adequate and consistent models of a collaboration during the entire life cycle of a collaboration. We propose a framework in which we connect business layer, process layer and implementation layer, presenting the direction for solving this multifaceted problem. We will describe several challenges we anticipate to encounter while implementing our framework.
Declarative Memory, Awareness, and Transitive Inference

A characteristic usually attributed to declarative memory is that what is learned is accessible to awareness. Recently, the relationship between awareness and declarative (hippocampus-dependent) memory has been questioned on the basis of findings from transitive inference tasks. In transitive inference, participants are first trained on overlapping pairs of items (e.g., A+B-, B+C-, C+D-, and D+E-, where + and - indicate correct and incorrect choices). Later, participants who choose B over D when presented with the novel pair BD are said to demonstrate transitive inference. The ability to exhibit transitive inference is thought to depend on the fact that participants have represented the stimulus elements hierarchically (i.e., A>B>C>D>E). We found that performance on five-item and six-item transitive inference tasks was closely related to awareness of the hierarchical relationship among the elements of the training pairs. Participants who were aware of the hierarchy performed near 100% correct on all tests of transitivity, but participants who were unaware of the hierarchy performed poorly (e.g., on transitive pair BD in the five-item problem; on transitive pairs BD, BE, and CE in the six-item problem). When the five-item task was administered to memory-impaired patients with damage thought to be limited to the hippocampal region, the patients were impaired at learning the training pairs. All patients were unaware of the hierarchy and, like unaware controls, performed poorly on the BD pair. The findings indicate that awareness is critical for robust performance on tests of transitive inference and support the view that awareness of what is learned is a fundamental characteristic of declarative memory.
The prevalence of azoospermia factor microdeletion on the Y chromosome of Chinese infertile men detected by multi-analyte suspension array technology.

AIM To develop a high-throughput multiplex, fast and simple assay to scan azoospermia factor (AZF) region microdeletions on the Y chromosome and establish the prevalence of Y chromosomal microdeletions in Chinese infertile males with azoospermia or oligozoospermia. METHODS In total, 178 infertile patients with azoospermia (non-obstructed), 134 infertile patients with oligozoospermia as well as 40 fertile man controls were included in the present study. The samples were screened for AZF microdeletion using optimized multi-analyte suspension array (MASA) technology. RESULTS Of the 312 patients, 36 (11.5%) were found to have deletions in the AZF region. The microdeletion frequency was 14% (25/178) in the azoospermia group and 8.2% (11/134) in the oligospermia group. Among 36 patients with microdeletions, 19 had deletions in the AZFc region, seven had deletions in AZFa and six had deletions in AZFb. In addition, four patients had both AZFb and AZFc deletions. No deletion in the AZF region was found in the 40 fertile controls. CONCLUSION There is a high prevalence of Y chromosomal microdeletions in Chinese infertile males with azoospermia or oligozoospermia. The MASA technology, which has been established in the present study, provides a sensitive and high-throughput method for detecting the deletion of the Y chromosome. And the results suggest that genetic screening should be advised to infertile men before starting assisted reproductive treatments.
Production and validation of isotope production cross-section libraries for neutrons and protons to 1.7-GeV

For validation and development of codes and for modeling isotope production in high power accelerators and APT Materials studies, we have produced experimental, calculated, and evaluated activation libraries for interaction of nucleons with nuclides covering about a third of all natural elements. For targets considered here, our compilation of experimental data is the most complete we are aware of, since it contains all data available on the Web, in journal papers, laboratory reports, theses, and books, as well as all data included in the large compilation by Sobolevsky with co-authors (NUCLEX) published recently by Springer-Verlag in 4 volumes. Our evaluated library was produced using all available experimental cross sections together with calculations by the CEM95, LAHET, and HMS-ALICE codes and with the European Activation File EAF-97 and LANL Update II of the ECNAF Neutron Activation Cross-Section Library.
An Efficient and Fast Broadcast Frame Adjustment Algorithm in VANET

Designing MAC protocol for vehicle ad hoc networks (VANETs) is challenging because of quick topology changes, high vehicle mobility, and different quality of service requirements. One promising approach is to employ both TDMA and CSMA hybrid access schemes in the control channel interval. These protocols can adjust the length of TDMA frame (also called broadcast frame) to adapt itself to different vehicle conditions and provide efficient non-safety message transmission. To improve the efficiency of the hybrid MAC mechanism in VANET, we propose an efficient and fast broadcast frame adjustment algorithm, called EFAB based on the three-hop neighbor information. By adjusting the broadcast frame length quickly, MAC protocol using EFAB can support efficient broadcast services on the control channel. Simulation results show that the hybrid MAC protocol using EFAB can provide faster broadcast frame adjustment and higher packet delivery ratio of safety packets on the control channel than using the existing algorithms.
Opinion polling and the measurement of Americans’ attitudes regarding education*

Abstract The meaning, measurement, and implications of ‘public opinion’ have long been a source of debate. In this paper, we examine the extent to which the educational priorities of elites in the US reflect the educational priorities of the American public. To do so, we focus on one particular segment of the education policy-making elite – education poll creators. Through a content analysis of questions asked between 1969 and 2013 in the Phi Delta Kappa/Gallup Poll of the Public’s Attitudes toward the Public Schools, we examine the salience of key educational issues over time. We compare these trends to the proportion of poll respondents who label those issues the ‘biggest problem’ facing schools, thereby approximating two different conceptions of public opinion regarding education. We find that the issues that receive the most coverage by pollsters do not typically match the issues that respondents claim to be the biggest problems in schools. In light of the important role that opinion polls may play in shaping discussion and debate over educational issues, we argue that further study of the construction of public opinion is warranted.
