Personalized Recommendation of Item Category Using Ranking on Time-Aware Graphs

SUMMARY Recommendation systems have been widely used in E-commerce sites, social media and etc. An important recommendation task is to predict items that a user will perform actions on with users’ historical data, which is called top-K recommendation. Recently, there is huge amount of emerging items which are divided into a variety of categories and researchers have argued or suggested that top-K recommendation of item category could be very beneﬁcial for users to make better and faster decisions. However, the traditional methods encounter some common but crucial problems in this scenario because additional information, such as time, is ignored. The ranking algorithm on graphs and the increasingly growing amount of online user behaviors shed some light on these problems. We propose a construction method of time-aware graphs to use ranking al-gorithm for personalized recommendation of item category. Experimental results on real-world datasets demonstrate the advantages of our proposed method over competitive baseline algorithms.
The stressor criterion for posttraumatic stress disorder: does it matter?

OBJECTIVE The definition of the stressor criterion (DSM criterion A1) for posttraumatic stress disorder (PTSD) is hotly debated with major revisions being considered for DSM-5. We examine whether symptoms, course, and consequences of PTSD vary predictably with the type of stressful event that precipitates symptoms. METHOD We used data from the 2009 PTSD diagnostic subsample (N = 3,013) of women from the Nurses' Health Study II. We asked respondents about exposure to stressful events that qualified under DSM-III or DSM-IV or did not qualify under DSM criterion A1. Respondents selected the event they considered worst and reported subsequent PTSD symptoms. Among participants who met all other DSM-IV PTSD criteria, we compared distress, symptom severity, duration, impairment, receipt of professional help, and 9 physical, behavioral, and psychiatric sequelae (eg, physical functioning, unemployment, depression) by precipitating event group. Various assessment tools were used to determine fulfillment of PTSD criteria B through F and to assess these 14 outcomes. RESULTS Participants with PTSD from DSM-III events reported, on average, 1 more symptom (DSM-III, mean = 11.8 symptoms; DSM-IV, mean = 10.7 [P < .001]; non-DSM, mean = 10.9 [P < .01]) and more often reported that symptoms lasted 1 year or longer compared to participants with PTSD from other groups (DSM-III vs DSM-IV, P < .01; DSM-III vs non-DSM, P < .001). However, sequelae of PTSD did not vary systematically with precipitating event type. CONCLUSIONS Results indicate the stressor criterion as defined by the DSM may not be informative in characterizing PTSD symptoms and sequelae. In the context of ongoing DSM-5 revision, these results suggest that criterion A1 could be expanded in DSM-5 without much consequence for our understanding of PTSD phenomenology. Events not considered qualifying stressors under the DSM produced PTSD as consequential as PTSD following DSM-III events, suggesting PTSD may be an aberrantly severe but nonspecific stress response syndrome.
Relationship of two arthropod-borne rhabdoviruses (kotonkan and Obodhiang) to the rabies serogroup

Indirect immunofluorescence confirmed the antigenic relationship between kotankan and Obodhiang viruses and Mokola virus that had originally been shown by complement fixation test. This relationship suggests inclusion of these two arthropod isolates in the rabies subgroup of the Rhabdoviridae family. Cross-reactivity with Mokola virus was also demonstrated by direct immunofluorescence but was easily eliminated when conjugates were diluted. No crossreactivities were found by neutralization tests or by surface immunofluorescence. Other than these immunological ties to the rabies serogroup, other biological characteristics of kotonkan and Obodhiang viruses were distinct. Maximum yield of infectivity of kotonkan and Obodhiang in cell culture was at 30 C, antigen usually filled the cytoplasm of infected cells diffusely, and syncytia were formed before severe cytonecrosis. By electron microscopy, virus particles and their nucleocapsids appeared cone shaped (mean lengths: kotonkan, 182 nm; Obodhiang, 170 nm). Viral morphogenesis took place on plasma membranes of cells in culture, mouse brain neurons, and inflammatory cells (macrophages) in brain lesions. All of these characteristics of the two viruses, and the known association of kotonkan virus with an acute, febrile illness of cattle in Nigeria, suggest a biological relationship with bovine ephemeral fever virus. The latter is known to exist in the same geographic area but exhibits no serological cross-reaction with either kotonkan or Obodhiang virus. The question of whether these two viruses deserve placement in an expanded rabies subgroup (at the cost of a less precise definition of the subgroup) or in a separate subgroup (which would include bovine ephemeral fever virus) of the Rhabdoviridae family will only be answered by further physicochemical characterization and comparison.
A Design of Terahertz Broadband Filters and its Effect in Eliminating Asymmetric Characteristics in Device Structures

We report a straightforward way to design polarization-insensitive broadband bandstop filters in terahertz range by fabricating identical metal patterns on both sides of a dielectric substrate with one layer rotated 90° to the other. The unit cells used in such designs are the well-studied split-ring-resonators, hence the frequency range of the stop band can be easily tuned by varying the dimensions of the unit cell structures. Through simulation analysis, we show that such fabrication method requires no alignment in lithography step and works with common dielectric substrates. Two types of substrates, 1-mm-thick quartz and 100-μm-thick polyethylene terephthalate, were used as a demonstration. The transmission level stayed below 12% for a stopband of 0.42-THz frequency range. Lastly, we reasoned with simulation results that the proposed broadband filters give consistent performance regardless of the gap location in the unit cell, which will further extend their use in practical applications.
Nyquist filters with robust performance against timing jitter

We propose two novel techniques for designing finite impulse response (FIR) Nyquist filters with zero intersymbol interference, good robustness to timing jitter and satisfactory stop-band performance. The first technique is a special kind of windowing method. The second technique is a minimax method resulting in equiripple FIR Nyquist filters which can be optimally partitioned into a matched transmit and receive filter pair. Examples show superior performance of the proposed pulse shapes compared to the existing techniques.
Planar Variable-Focus Liquid Lens Based on Electrowetting on Dielectric

In this paper, a new type of liquid lens based on electrowetting on dielectric (EWOD) is demonstrated. It consists of a transparent liquid droplet as lens on a hydrophobic dielectric film, a patterned indium tin oxide (ITO) film as a set of transparent electrodes underneath and a glass substrate. By changing the applied voltage on the set of electrodes, the shape and location of the droplet can be adjusted reversibly which tune the focal length and position of the lens. It has some good qualities such as wide variability of focal length up to 20%, fast response time, low applied voltage and low power consumption. It can be used widely in optical application.
Optogenetic experimentation on astrocytes

We briefly review the current literature where optogenetics has been used to study various aspects of astrocyte physiology in vitro and in vivo. This includes both genetically engineered Ca2+ sensors and effector proteins, such as channelrhodopsin. We demonstrate how the ability to target astrocytes with cell‐specific viral vectors to express optogenetic constructs helped to unravel some previously unsuspected roles of these inconspicuous cells.

Cognitive rehabilitation for spatial neglect following stroke.

BACKGROUND Unilateral spatial neglect is a failure to attend to one side of space. Various strategies have been used to treat these problems but evidence of their benefit has been lacking. OBJECTIVES To determine the effects of cognitive rehabilitation for spatial neglect following stroke as measured on impairment and disability level assessments, and destination on discharge from hospital. To determine whether any effects persist at follow-up assessment. SEARCH STRATEGY We searched the Cochrane Stroke Group Trials Register (last searched February 2001), MEDLINE (1966-December 2000), EMBASE (1980-February 2001), CINAHL (1983-January 2001), PSYCLIT and CLINPSYCH (1974-February 2001). We handsearched relevant journals, screened reference lists from relevant articles and tracked citations using SCISEARCH. SELECTION CRITERIA Controlled trials of cognitive rehabilitation for spatial neglect in stroke. Studies with mixed patient groups were excluded unless more than 75% of their sample were stroke patients or separate stroke data were available for stroke patients. DATA COLLECTION AND ANALYSIS Two reviewers independently selected trials, extracted data, and assessed trial quality. MAIN RESULTS We included 15 studies with 400 participants. A large number of different outcome measures were reported. Only six studies included a measure of disability and only four (111 participants) investigated persisting effects on any outcome. There was evidence that cognitive rehabilitation resulted in significant and persisting improvements in performance on impairment level assessments, although this varied depending on the test used. There was insufficient evidence to confirm or exclude an effect of cognitive rehabilitation at the level of disability or on destination following discharge from hospital. REVIEWER'S CONCLUSIONS There is some evidence that cognitive rehabilitation for spatial neglect improves performance on some impairment level tests but its effect on disability is unclear. Further well-designed RCTs are warranted as well as basic research to develop valid outcome measures.
Randomized trial of 2 interventions to increase older women's exercise.

OBJECTIVE To test 2 interventions to increase older women's physical activity. METHODS A randomized 2-way factorial experimental design compared the effects of 2 limited-contact interventions, motivational sessions and periodic prompts, among 190 women. Experimental participants received a 3-encounter motivational intervention. Those randomized to prompts received weekly telephone or mail-delivered cues. RESULTS The prompting intervention consistently increased exercise and physical activity scores. The motivational intervention did not affect outcome scores. CONCLUSIONS Prompting is a low-cost strategy for increasing exercise and physical activity among older women. Future research should examine alternative modes for prompt delivery.
A Framework for Efficient Energy Scheduling of Spark Workloads

Nowadays distributed processing frameworks like Apache Spark have been successfully used for the execution of big data applications. Despite their wide adoption little work has been done in terms of controlling the applications' energy consumption. Datacenters contribute over 2 % of the total US electric usage therefore minimizing the energy utilization of Spark application can be extremely helpful. Solving this energy consumption problem requires the scheduling of Spark applications in an energy-efficient way. However, the problem is challenging as we also have to consider application performance requirements. In this work, we provide the overview of a novel framework that orchestrates the execution order of Spark applications, exploiting DVFS to tune the computing nodes CPU frequencies in order to minimize the energy consumption and satisfy application's performance requirements. Our early experimental results illustrate the working and benefits of our framework.
Methods used by adolescents for reducing body mass.

BACKGROUND During adolescence teenagers undergo dynamic physical and mental changes which are accompanied by an increasing interest in changes to their external appearance. Often teens are concerned about such changes, leading to attempts at managing body mass reduction. Adolescent slimming more commonly arises due to a subjective appraisal of body mass rather than using any objective BMI indicators. OBJECTIVE To evaluate nutritional status of 13 year old boys and girls living in Szczecin, Poland and to analyse the methods used for achieving body mass reduction. MATERIALS AND METHODS Subjects were 1,342 adolescents consisting of 679 girls and 663 boys. Nutritional assessment was performed by anthropometric measurements; calculated BMI (Body Mass Index) and WC (Waist Circumference index). A questionnaire was also used to determine how the subjects lost body mass, their satisfaction levels, mood changes and physical activity. RESULTS Only 73% subjects had an adequate/normal nutritional status. It was found that half of those declaring that they had used various means of losing body mass (13.04%), of whom the majority were girls, had normal BMI indicators. The most frequently used method of losing body mass were; reducing foodstuff portions and dishes, abstaining from dinner, 1-3 starvation days, increasing physical activity, reducing sweets consumption, abstaining altogether from sweets and increasing fruit and vegetable consumption. Slimming diets were undertaken by 13.1% subjects, consisting mainly of 1000-1300 kcal diets, vegetarian diets or ones recommended by a physician. CONCLUSIONS Adolescents living in Szczecin showed similar rates of adopting slimming diets for reducing body mass when compared to other regions of Poland and the rest of Europe. The methods used for this purpose were mainly either anti- or pro-healthy nutritional behaviour, but less often using physical activity or through slimming diets. It thus appears that monitoring nutritional status in adolescents, as well as providing education in pro-healthy nutrition, is necessary.
Comparison between segmented and nonsegmented attenuation correction on the HR+ tomograph

Segmentation of transmission (TR) images is implemented to improve signal noise in attenuation correction (AC) and allow shorter TR scans. This study compares (i) measurement of myocardial glucose metabolic rate (MRGlu), (ii) correction for myocardial wall thickness and (iii) measurement of lung density, by using AC derived from transmission images (a) unsegmented (US), (b) segmented (S) and (c) reconstructed with OSEM. All data were acquired on a CTI HR+ tomograph and processed with standard scanner software. Methods: TR scans were carried out on a multi-cylinder phantom containing substances of varying density and mean mu-values (cm-1) were derived from TR images. A multi-compartment heart phantom was constructed as a simple simulation of varying myocardial wall thickness and left ventricular volume. MRGlu, using FDG (2D mode) and blood volume (C15O inhalation), was measured in 11 patients with coronary heart disease, following a 20 min TR scan. Results: Good linearity was found between NS mu-values and density but there were significant discrepancies with S over the typical range of lung density, and better agreement with OSEM. Overall mean ratios of MRGlu were within 2% for the three AC methods but there was systematic individual variation about the mean. The C.V. of regional MRGlu for each patient, using US AC, was not significantly different from S and OSEM. The heart phantom data demonstrated reasonable accuracy of correction for myocardial wall thickness. Conclusions: US AC on the HR+ gives more accurate measurement of the range of density encountered in the chest and more reliable measurement of MRGlu than S and OSEM. There appears to be no "statistical penalty" in the use of US AC, noise being dominated by that in emission data
Cytotoxic and Antimigratory Activities of Phenolic Compounds from Dendrobium brymerianum

Chromatographic separation of a methanol extract prepared from the whole plant of Dendrobium brymerianum led to the isolation of eight phenolic compounds. Among the isolated compounds (1–8), moscatilin (1), gigantol (3), lusianthridin (4), and dendroflorin (6) showed appreciable cytotoxicity against human lung cancer cell lines with IC50 values of 196.7, 23.4, 65.0, and 125.8 μg/mL, respectively, and exhibited antimigratory property at nontoxic concentrations. This study is the first report on the biological activities of this plant.
Testing of memristor ratioed logic (MRL) XOR gate

This paper focuses on the production testing of Memristor Ratioed Logic (MRL) XOR gate. MRL is a family that uses memristors along with CMOS inverters to design logic gates. The two-input MRL XOR gate is investigated using the stuck at fault model for the memristors and the five-fault model for the transistors. It is shown that faults in the XOR gate produce analog output voltage values because of the circuit architecture. Therefore, a 2-bit Flash ADC is used as a special test equipment to achieve full fault coverage. Finally, four resistive short faults in the XOR gate can only be detected by monitoring the input current. It is shown that exhaustive testing is needed in order to obtain 100% fault coverage.
The Interplay between Sulfur and Iron Nutrition in Tomato1[OPEN]

Single and combined Fe and S starvation of plants induces a complex partially overlapping regulatory system to coordinate the starvation response. Plant response mechanisms to deficiency of a single nutrient, such as sulfur (S) or iron (Fe), have been described at agronomic, physiological, biochemical, metabolomics, and transcriptomic levels. However, agroecosystems are often characterized by different scenarios, in which combined nutrient deficiencies are likely to occur. Soils are becoming depleted for S, whereas Fe, although highly abundant in the soil, is poorly available for uptake because of its insolubility in the soil matrix. To this end, earlier reports showed that a limited S availability reduces Fe uptake and that Fe deficiency results in the modulation of sulfate uptake and assimilation. However, the mechanistic basis of this interaction remains largely unknown. Metabolite profiling of tomato (Solanum lycopersicum) shoots and roots from plants exposed to Fe, S, and combined Fe and S deficiency was performed to improve the understanding of the S-Fe interaction through the identification of the main players in the considered pathways. Distinct changes were revealed under the different nutritional conditions. Furthermore, we investigated the development of the Fe deficiency response through the analysis of expression of ferric chelate reductase, iron-regulated transporter, and putative transcription factor genes and plant sulfate uptake and mobilization capacity by analyzing the expression of genes encoding sulfate transporters (STs) of groups 1, 2, and 4 (SlST1.1, SlST1.2, SlST2.1, SlST2.2, and SlST4.1). We identified a high degree of common and even synergistic response patterns as well as nutrient-specific responses. The results are discussed in the context of current models of nutrient deficiency responses in crop plants.
On-line identification of an electronic component placement process using a potential fuzzy clustering scheme

This paper presents an evolutionary potential fuzzy clustering approach for on-line identification of an electronic component placement process in the pick-and-place machines. The main idea is to identify a global nonlinear fuzzy model of the component placement process. In the proposed approach, the fuzzy clustering method utilizes an on-line potential clustering scheme to form the antecedent part of fuzzy rule-based models using an evolving Takagi-Sugeno (eTS) structure adaptation algorithm. A new on-line approach is proposed to control the rate of rule creation mechanism. The effectiveness of the proposed approach is evaluated by comparing the achieved results with some well-known approaches.
Nuclear Targeting of the Cauliflower Mosaic Virus Coat Protein

ABSTRACT The entry of the viral genomic DNA of cauliflower mosaic virus into the nucleus is a critical step of viral infection. We have shown by transient expression in plant protoplasts that the viral coat protein (CP), which is processed from the product of open reading frame IV, contains an N-terminal nuclear localization signal (NLS). The NLS is exposed on the surface of the virion and is thus available for interaction with a putative NLS receptor. Phosphorylation of the matured CP did not influence the nuclear localization of the protein but improved protein stability. Mutation of the NLS completely abolished viral infectivity, thus indicating its importance in the virus life cycle. The NLS seems to be regulated by the N terminus of the precapsid, which inhibits its nuclear targeting. This regulation could be important in allowing virus assembly in the cytoplasm.
Segregation of Bad from Lipid Rafts Is Implicated in the Induction of Apoptosis1

Many molecules relocate subcellularly in cells undergoing apoptosis. Using coimmunoprecipitation experiments we demonstrate that Bad is not associated to 14-3-3 protein, suggesting a new mechanism for the control of the proapoptotic role of Bad. Here we show, by confocal microscopy and cellular fractionation, that Bad is attached to lipid rafts in IL-4-stimulated cells and thymocytes while associated with mitochondria in IL-4-deprived cells. Disruption of lipid rafts by methyl-β-cyclodextrin treatment induces segregation of Bad from rafts, which correlates with apoptosis. Our results suggest that the interaction of Bad with rafts is a dynamic process regulated by IL-4 and involved in the control of apoptosis.
Proposal of a reference model for fashionable and healthy goods production in SME networks

In order to stay competitive, European manufacturing companies need to enter new market segments implementing innovative production methodologies to strengthen their collaborative networks. Consumer needs and expectations of specific target groups - such as elderly, obese, disabled, or diabetic persons - are arising as challenging opportunities for European consumer goods companies which are asked to supply small series of functional and fashionable products of high quality, affordable price and eco-compatible. This paper aims at proposing an innovative collaborative Reference Model that supports in Textile, Clothing and Footwear (TCF) supply networks in meeting the needs of specific consumer target groups.
