An Adaptive Dynamic Topology WSN Data Collection Method Based on Compressive Sensing

I412 order to further improve the efficiency of data collection in wireless sensor networks with dynamic topology, a two stage dynamic topology compression sensing (DTCS) data collection algorithm is designed. First stage, a collection tree by using the method of maximal independent set is constructed. Second stage, the sensor nodes in the network obtains the local topology information by mutual communication. Then, according to the topology changing, the adaptive strategy is adopted to maintain the collection tree. And data is collected by compressive sensing method. Simulation experiment results show that, while ensuring the accuracy of data reconstruction, the number of measurements is reduced by the DTCS algorithm.
The phase of pre‐stimulus brain oscillations correlates with cross‐modal synchrony perception

In everyday life multisensory events, such as a glass crashing on the floor, the different sensory inputs are often experienced as simultaneous, despite the sensory processing of sound and sight within the brain are temporally misaligned. This lack of cross‐modal synchrony is the unavoidable consequence of different light and sound speeds, and their different neural transmission times in the corresponding sensory pathways. Hence, cross‐modal synchrony must be reconstructed during perception. It has been suggested that spontaneous fluctuations in neural excitability might be involved in the temporal organisation of sensory events during perception and account for variability in behavioural performance. Here, we addressed the relationship between ongoing brain oscillations and the perception of cross‐modal simultaneity. Participants performed an audio‐visual simultaneity judgement task while their EEG was recorded. We focused on pre‐stimulu activity, and found that the phase of neural oscillations at 13 ± 2 Hz 200 ms prior to the stimulus correlated with subjective simultaneity of otherwise identical sound‐flash events. Remarkably, the correlation between EEG phase and behavioural report occurred in the absence of concomitant changes in EEG amplitude. The probability of simultaneity perception fluctuated significantly as a function of pre‐stimulus phase, with the largest perceptual variation being accounted for phase angles nearly 180º apart. This pattern was strongly reliable for sound‐flash pairs but not for flash‐sound pairs. Overall, these findings suggest that the phase of ongoing brain activity might underlie internal states of the observer that influence cross‐modal temporal organisation between the senses and, in turn, subjective synchrony.
Large Scale GAN Training for High Fidelity Natural Image Synthesis

Despite recent progress in generative image modeling, successfully generating high-resolution, diverse samples from complex datasets such as ImageNet remains an elusive goal. To this end, we train Generative Adversarial Networks at the largest scale yet attempted, and study the instabilities specific to such scale. We find that applying orthogonal regularization to the generator renders it amenable to a simple "truncation trick," allowing fine control over the trade-off between sample fidelity and variety by reducing the variance of the Generator's input. Our modifications lead to models which set the new state of the art in class-conditional image synthesis. When trained on ImageNet at 128x128 resolution, our models (BigGANs) achieve an Inception Score (IS) of 166.5 and Frechet Inception Distance (FID) of 7.4, improving over the previous best IS of 52.52 and FID of 18.6.
Reuse and Adaptation for Entity Resolution through Transfer Learning

Entity resolution (ER) is one of the fundamental problems in data integration, where machine learning (ML) based classifiers often provide the state-of-the-art results. Considerable human effort goes into feature engineering and training data creation. In this paper, we investigate a new problem: Given a dataset D_T for ER with limited or no training data, is it possible to train a good ML classifier on D_T by reusing and adapting the training data of dataset D_S from same or related domain? Our major contributions include (1) a distributed representation based approach to encode each tuple from diverse datasets into a standard feature space; (2) identification of common scenarios where the reuse of training data can be beneficial; and (3) five algorithms for handling each of the aforementioned scenarios. We have performed comprehensive experiments on 12 datasets from 5 different domains (publications, movies, songs, restaurants, and books). Our experiments show that our algorithms provide significant benefits such as providing superior performance for a fixed training data size.
Effects of Acute Exercise Combined with Calorie Restriction Initiated Late-in-Life on Insulin Signaling, Lipids and Glucose Uptake in Skeletal Muscle from Old Rats.

We evaluated effects of calorie restriction (CR: consuming 60-65% of ad libitum [AL] intake) initiated late-in-life with or without acute exercise on insulin-stimulated glucose uptake (ISGU) of skeletal muscle by studying 4 groups of 26-month-old rats: sedentary-AL, sedentary-CR (8-week duration), 3-hours post-exercise (3hPEX)-AL and 3hPEX-CR. ISGU was determined in isolated epitrochlearis muscles incubated ±insulin. Muscles were assessed for signaling proteins (immunoblotting) and lipids (mass spectrometry). ISGU from sedentary-CR and 3hPEX-AL exceeded sedentary-AL; 3hPEX-CR exceeded all other groups. Akt (Ser473, Thr308) and Akt substrate of 160 kDa (AS160; Ser588, Thr642, Ser704) phosphorylation levels tracked with ISGU. Among the 477 lipids detected, 114 were altered by CR (including reductions in 15 of 25 acylcarnitines), and 27 were altered by exercise (including reductions in 18 of 22 lysophosphatidylcholines) with only 6 lipids overlapping between CR and exercise. ISGU significantly correlated with 23 lipids, including: acylcarnitine 20:1 (r=0.683), lysophosphatidylethanolamine19:0 (r=-0.662), acylcarnitine 24:0 (r=0.611), and plasmenyl-phosphatidylethanolamine 37:5 (r=-0.603). Muscle levels of ceramides (a lipid class previously linked to insulin resistance) were not altered by CR and/or exercise nor significantly correlated with ISGU, implicating other mechanisms (which potentially involve other lipids identified in this study) for greater ISGU and Akt and AS160 phosphorylation with these interventions.
Natural Esters and Mineral Oils Fire Behavior

In recent times, the use of natural esters (vegetable fluids) in power transformers is having a considerable increase due to their advantages in terms of high flash/fire points, lower toxicity, higher biodegradability and possibility of recycling. This paper presents an experimental comparative evaluation on fire ignition of both mineral oil and natural esters in different experimental conditions. The results shown in the present paper give a contribution to ascertain that the use of natural ester transformer may positively contribute to a significant reduction of risks to humans and the environment
Ion Current Measurements in Air for HVDC Applications

The knowledge of the external field distribution around High-Voltage Direct Current (HVDC) apparatus and lines is important, and the importance of accurate knowledge of the fields in air is expected to increase with increasing voltages. Consequently, the study of the non-linear relation between the electric field and the electric current in air is necessary as a way to understand how charges in this gaseous medium affect the DC electric field. In order to identify the main factors that influence the charge generation process, the ionic current in air was measured under uniform electric field in a plate-plate setup. Different environmental conditions and electrode configurations were also studied to understand what parameters affected the charge generation process. The specific parameters investigated were electric field magnitude, surface roughness, humidity, temperature and distance between electrodes. The test results showed that the electric field magnitude, humidity and surface roughness had the largest influence on the charge generation process. The ionic current presents an exponential behavior with the applied electric field and the humidity. The measured ion current reached higher magnitudes compared to what can be expected from only cosmic rays and background radiation production of charge carriers. The experimental results show that there is a strong charge injection process close to the surface already in the pre-corona region. The exponential increase of current with humidity and electric field due to charge injection is not well described by available models. In particular, there is insufficient information about strongly field dependent charge generation processes in air under DC-electric fields in the pre-corona region.
Intercostal Nerve Blockade with Exparel® Results in Lower Opioid Usage during the First 24 Hours after Video-Assisted Thorascopic Surgery

Liposomal bupivacaine (LipoB) provides prolonged local anesthetic effects and has seen usage in several fields of surgery. We review our experience using LipoB intraoperatively for intercostal nerve blocks after video-assisted throacoscopic surgery (VATS). A retrospective, single-center review was conducted for patients undergoing VATS from August 2012 to December 2014. Patients those who received LipoB as an intercostal nerve block were compared with patients who received blocks with standard bupivacaine. Opiate amounts used within the first six hours and then subsequent 18,48, and 72 hours were converted into morphine equivalents for comparison. Forty-seven patients met inclusion criteria: 21 receiving LipoB intercostal nerve block and 26 controls. Groups were similar for age, diabetes, hypertension, chronic kidney disease, body mass index and American Society of Anesthesiologists scores. The LipoB group had a larger portion of males (P < 0.02). Postoperatively, morphine equivalent usage was significantly less in the LipoB group compared with the standard bupivacaine within the first six hours after surgery (15.62 vs 52.41, P = 0.001) and in the subsequent 18 hours (28.98 vs 65.17, P = 0.01). After the first 24 hours there was not a significant difference in opiate usage between the two groups. There was no difference in length of stay between the two groups. In our study group of VATS patients, an intercostal nerve block with LipoB significantly reduced the usage of postoperative opioids in the first 24 hours only when compared with standard bupivacaine.

The Valuing of Mathematics Learning in Schools: A Gendered Perspective

In this article, gender differences in the valuing of mathematics by Hong Kong primary and secondary students have been investigated. The participants were 1081 upper primary school (Grades 5 and 6) and secondary school (Grades 8 and 9) students from various metropolitan Hong Kong schools. An Analysis of Variance (ANOVA) was conducted to investigate the existence of gender differences on a number of values components. Statistically significant differences between boys’ and girls’ valuing of mathematics learning were found on three of the nine components derived via a Principal Component Analysis (PCA).
Field Validated Generic EMT-Type Model of a Full Converter Wind Turbine Based on a Gearless Externally Excited Synchronous Generator

The integration of wind power plants introduces new dynamics into power systems, forcing reconsiderations of how they are studied, planned, and operated. High quality models are essential to these studies. Manufacturer-specific electromagnetic transient (EMT) wind turbine models are usually available only as black-boxes, which hinders analysis and research. To overcome this issue, this paper proposes a generic EMT-type model for a specific type-IV wind turbine system, which is validated against field measurements from a wind turbine of the same type. More precisely, it proposes a wind turbine model based on an externally excited synchronous generator system connected to a full converter composed of a six-pulse diode rectifier, a dc–dc boost stage and a two-level voltage source converter. The required control features and internal protection schemes are considered and described. Two different fault ride-through control strategies, in line with existing grid codes, are implemented. A corresponding EMT-type hybrid model representation is also developed based on newly proposed switched equivalent circuits and average models for the considered hardware, control, and power electronics stages. It allows for the use of larger simulation time steps, hence considerably improving computation times.
miR-29a suppresses the growth and metastasis of hepatocellular carcinoma through IFITM3

The interferon-induced transmembrane protein 3 (IFITM3, also called 1-8U) gene represents dysregulated expression in various tumors and is involved in tumorigenesis and progression. However, the role of IFITM3 and its underlying mechanism in hepatocellular carcinoma (HCC) are still far from elucidated. MicroRNAs (miRNAs), a class of endogenous (approximately 22 nucleotides) small noncoding RNAs, can post-transcriptionally regulate gene expression by repressing protein translation or silencing the expression of target genes that play critical roles in various cancers. miR-29a was identified as being aberrantly expressed in a significant proportion of HCC. However, the correlation between IFITM3 and miR-29a has not been reported to date. In this study, we investigated the expression of IFITM3 in HCC and its effect on the biological behavior of HCC cells as well as the association between IFITM3 and miR-29a. We determined that IFITM3 was upregulated and miR-29a downregulated in HCC tissues and that they were associated with HCC tumor size, tumor multifocal, and venous invasion. The expression of IFITM3 in HCC tissues was negatively correlated with miR-29a expression. Additionally, IFITM3 overexpression and miR-29a nonoverexpression were related to poor prognosis of HCC patients. Knockdown of IFITM3 inhibited migration, invasion, proliferation and promoted apoptosis of HCC cells, which are consistent with the effects of upregulated miR-29a. Additionally, after upregulation of IFITM3, the invasion, migration and proliferation abilities of HL-7702 cells were increased, but the apoptosis rate was decreased. Furthermore, using a Dual-Luciferase reporter gene assay, we identified IFITM3 as a new functional target gene of miR-29a. In conclusion, our findings demonstrated that the migration, invasion, proliferation and apoptosis features of HCC cells could be regulated by miR-29a via IFITM3. Thus, the present study indicated that miR-29a and IFITM3 play critical roles in the development and progression of HCC, revealing that miR-29a and IFITM3 may be novel potential therapeutic targets for patients with HCC.
Race/Ethnicity-, Socioeconomic Status-, and Anatomic Subsite-Specific Risks for Gastric Cancer.

Anatomic subsite risk factors for gastric cancer differ substantially, and subsite-specific distribution of risk factors (such as Helicobacter pylori) can vary by race and ethnicity and neighborhood socioeconomic status (nSES). We examined differences in gastric cancer incidence by subsite, stratified by race and ethnicity and nSES, using Surveillance Epidemiology and End Results Program 2000-2014 data for 77,881 incident gastric cancer cases (cardia, n = 23,651; non-cardia, n = 35,825; overlapping or unspecified, n = 18,405). Compared with non-Hispanic whites, cardia cancer multivariable-adjusted incidence rate ratios were 35%-47% lower for blacks, Hispanics, Asian or Pacific Islanders, and American Indian or Alaska Natives; conversely, non-cardia incidence rate ratios were 1.7- to 3.9-fold higher for blacks, Hispanics, Asian or Pacific Islanders, and American Indian or Alaska Natives. Higher adjusted incidence rate ratios with decreasing nSES (lowest vs highest nSES quintile) were observed for all gastric (1.3-fold) and non-cardia (1.3-fold) cancers but were borderline significant for cardia cancers (1.1-fold). In conclusion, non-cardia cancer incidence is higher in minorities and varies by nSES, but cardia cancer incidence is higher in non-Hispanic whites and does not vary substantially by nSES. Clarifying reasons for higher cardia risk in non-Hispanic whites and targeted interventions to address non-cardia cancer risk in minorities could lessen the burden of gastric cancer.
An Empirical Comparison of Syllabuses for Curriculum Learning

Syllabuses for curriculum learning have been developed on an ad-hoc, per task basis and little is known about the relative performance of different syllabuses. We identify a number of syllabuses used in the literature. We compare the identified syllabuses based on their effect on the speed of learning and generalization ability of a LSTM network on three sequential learning tasks. We find that the choice of syllabus has limited effect on the generalization ability of a trained network. In terms of speed of learning our results demonstrate that the best syllabus is task dependent but that a recently proposed automated curriculum learning approach - Predictive Gain, performs very competitively against all identified hand-crafted syllabuses. The best performing hand-crafted syllabus which we term Look Back and Forward combines a syllabus which steps through tasks in the order of their difficulty with a uniform distribution over all tasks. Our experimental results provide an empirical basis for the choice of syllabus on a new problem that could benefit from curriculum learning. Additionally, insights derived from our results shed light on how to successfully design new syllabuses.
Association Analysis of Somatic Copy Number Alteration Burden With Breast Cancer Survival

The increasing prevalence of diagnosed breast cancer cases emphasizes the urgent demand for developing new prognostic breast cancer biomarkers. Copy number alteration (CNA) burden measured as the percentage of the genome affected by CNAs has emerged as a potential candidate to this aim. Using somatic CNA data obtained from METABRIC (Molecular Taxonomy of Breast Cancer International Consortium), we implemented Kaplan-Meier estimators and Cox proportional hazards models to examine the association of CNA burden with patient’s overall survival (OS) and disease specific survival (DSS). We also evaluated the association by considering patients’ age and tumor subtypes using stratified Cox models. We delineated the distribution of CNA burden in sample genomes and highlighted chromosomes 1, 8, and 16 as the carriers of the highest CNA burden. We identified a strong association between CNA burden and age as well as CNA burden and breast cancer PAM50 subtypes. We found that controlling the effects of both age (bound by 45-year) and PAM50 subtypes on patient survival using stratified Cox models, would still result in significant association between CNA burden and patients overall survival in both Discovery and Validation data. The same trend was observed in disease specific survival when only PAM50 subtypes were controlled in the stratified Cox models. Our analysis showed that there is a significant association between CNA burden and breast cancer survival. This result is also validated by using TCGA (The Cancer Genome Atlas) data. CNA burden of breast cancer patients has a considerable potential to be used as a novel prognostic biomarker.
Higenamine protects neuronal cells from oxygen‐glucose deprivation/reoxygenation‐induced injury

Higenamine, a plant‐based alkaloid, exhibits various properties, such as antiapoptotic and antioxidative effects. Previous studies proved that higenamine possesses potential therapeutic effects for ischemia/reperfusion (I/R) injuries. However, the role of higenamine in cerebral I/R injury has not been fully evaluated. Therefore, we aimed to investigate the effect of higenamine on cerebral I/R injury and the potential mechanism. Our data showed that higenamine ameliorated oxygen‐glucose deprivation/reperfusion (OGD/R)‐induced neuronal cells injury. Induction of reactive oxygen species and malonaldehyde production, and the inhibition of superoxide dismutase and glutathione peroxidase activity caused by OGD/R were attenuated by higenamine. In addition, higenamine inhibited the increases in caspase‐3 activity and Bax expression, and inhibited the decrease in Bcl‐2 expression. Furthermore, higenamine elevated the expression levels of p‐Akt, heme oxygenase‐1 (HO‐1) and nuclear factor erythroid 2‐related factor 2 (Nrf2). The inhibitor of PI3K/Akt (LY294002) abolished the protective effects of higenamine on OGD/R‐induced neuronal cells. These findings indicated that higenamine protects neuronal cells against OGD/R‐induced injury by regulating the Akt and Nrf2/HO‐1‐signaling pathways. Collectively, higenamine might be considered as new strategy for the prevention and treatment of cerebral I/R injury.
Early Gesture Provides a Helping Hand to Spoken Vocabulary Development for Children with Autism, Down Syndrome, and Typical Development

ABSTRACT Typically developing (TD) children refer to objects uniquely in gesture (e.g., point at a cat) before they produce verbal labels for these objects (“cat”). The onset of such gestures predicts the onset of similar spoken words, showing a strong positive relation between early gestures and early words. We asked whether gesture plays the same door-opening role in word learning for children with autism spectrum disorder (ASD) and Down syndrome (DS), who show delayed vocabulary development and who differ in the strength of gesture production. To answer this question, we observed 23 18-month-old TD children, 23 30-month-old children with ASD, and 23 30-month-old children with DS 5 times over a year during parent–child interactions. Children in all 3 groups initially expressed a greater proportion of referents uniquely in gesture than in speech. Many of these unique gestures subsequently entered children’s spoken vocabularies within a year—a pattern that was slightly less robust for children with DS, whose word production was the most markedly delayed. These results indicate that gesture is as fundamental to vocabulary development for children with developmental disorders as it is for TD children.
Numerical Simulation of Electric Field Distribution along the DC-GIL Spacer with SF6/N2 Mixture

The flashover faults due to surface charge accumulation have restricted the further development of GIS/GIL spacers in HVDC transmission system. Many researchers have proposed a variety of mathematical models to simulate the surface charge accumulation process. However, few of them took the gas collision ionization and charge trappingdetrapping process into consideration. This paper combined the plasma hydrodynamics and charge transport equations and built a modified model. Some conclusions are shown as below: For the basin-type spacer, the surface charge has the same polarity as the applied voltage on the lower surface but the opposite polarity on the upper surface. A density drop and even a polarity reversal of surface charge is observed near the conductor. Under load condition, there is an obvious temperature rise on the conductor due to joule heating, which has a great influence on the electric field distribution. As the conductor temperature increases, the field strength near the conductor is weakened owing to the temperature-dependent volume conductivity of the epoxy spacer. The application of shielding electrodes has the function of field grading at the triple junction, which can be referred in the DC GIS/GIL design.
