Error correction method based on multiple neural networks for UHF partial discharge localization

The time difference method based ultra-high-frequency (UHF) partial discharge (PD) localization has not been extensively applied in substations due to its excessive localization error. A novel and effective PD localization error correction method, consisting of two multiple radial basis function (RBF) networks, RBFt for time delay error correction and RBFp for PD position error correction, is reported in this paper as a solution. Furthermore, the RBFt, trained by time delay value measured in field experiments and RBFp, trained by the localization results corrected by RBFt, have both adopted the multiple neural networks structure which could further improve their error correction ability. The field tests proved that, the error correction networks RBFt and RBFp have strong ability to learn and simulate the error distribution. After the error correction and compensation, the PD distance localization error is reduced from 3m to 0.5m and the direction angle error is reduced from 12° to less than 5°. Universality experiments also revealed that the proposed method has a good adaptability for different time-delay algorithms and different types of PD models, which proved the robustness and effectiveness of proposed method.
Objektivisering: Text Physicalization and Self-introspective Post-digital Objecthood

Objektivisering is an experimental system for the computational modeling of generative 3D-printable models. The system pivots on Natural Language Understanding technologies and big 3D data. It processes arbitrary text input, eventually generating an array of words and phrases that summarise its meaning. These are then used as queries to retrieve 3D data from Thingiverse. Finally, the resulting bag of models is concatenated, in this way producing original 3D-printable designs in a computational fashion. Albeit being concretely physical, the resulting artefacts also incorporate the cybernetic encodings of their own making. They celebrate a certain kind of objecthood which is hybrid, post-digital, and self-introspective at a structural level, in this way concretely accelerating materialist aesthetics.
Controlling swarm robots with kinematic constraints for target search

An approach to control artificial swarm whose members are autonomous wheeled mobile robots is proposed, by applying Particle Swarm Optimization (PSO) to target search. First, swarm search is mapped to PSO based on similarities between the two cases. Then a distributed PSO-style algorithm is given, in which decision making on real inputs of linear and angular velocity of robot controller being explored. We obtain the required command sequences by constraining the computational expected velocities and positions with robot's non-holonomic properties in kinematics. In this way, swarm robots can work together cooperatively.
Using structural equation modelling to assess factors influencing children’s growth and nutrition in rural China

Abstract Objective Children’s poor growth and nutrition status has serious consequences and therefore it is important to understand its contributing factors. Design A community-based interventional study focusing on child feeding was conducted in a rural community in China. Data from the intervention group at baseline (1–4 months of age) and follow-up visits (12 and 18 months of age) were used in the present study (n 236). A structural equation model was generated to explore the effects of family wealth, household food safety, dietary intake, diseases and other factors on the growth and nutrition of young children. Results Mother’s knowledge and behaviours on household food safety had positive effects on children’s weight-for-age Z-score (WAZ; β direct=0·03 and 0·15, respectively, at 12 months of age; β direct=0·02 and 0·08, respectively, at 18 months; P<0·05) and weight-for-length Z-score (WLZ; β direct=0·04 and 0·21, respectively, at 12 months of age; β direct=0·01 and 0·06, respectively, at 18 months; P<0·05). While mothers’ feeding behaviours and children’s dietary intake at 12 months of age were positively associated with WAZ and/or WLZ at current and later ages, children’s diseases were negatively associated with WAZ and WLZ cross-sectionally. Conclusions Caregiver’s knowledge and feeding behaviours, and children’s dietary intake and diseases, are factors influencing the WAZ and WLZ of children. Promoting feeding and health knowledge and behaviours at early stages of childhood can improve children’s physical growth at later ages.
Asynchronous Response of Tropical Forest Leaf Phenology to Seasonal and El Niño-Driven Drought

The Hawaiian Islands are an ideal location to study the response of tropical forests to climate variability because of their extreme isolation in the middle of the Pacific, which makes them especially sensitive to El Niño-Southern Oscillation (ENSO). Most research examining the response of tropical forests to drought or El Niño have focused on rainforests, however, tropical dry forests cover a large area of the tropics and may respond very differently than rainforests. We use satellite-derived Normalized Difference Vegetation Index (NDVI) from February 2000-February 2009 to show that rainforests and dry forests in the Hawaiian Islands exhibit asynchronous responses in leaf phenology to seasonal and El Niño-driven drought. Dry forest NDVI was more tightly coupled with precipitation compared to rainforest NDVI. Rainforest cloud frequency was negatively correlated with the degree of asynchronicity (ΔNDVI) between forest types, most strongly at a 1-month lag. Rainforest green-up and dry forest brown-down was particularly apparent during the 2002–003 El Niño. The spatial pattern of NDVI response to the NINO 3.4 Sea Surface Temperature (SST) index during 2002–2003 showed that the leeward side exhibited significant negative correlations to increased SSTs, whereas the windward side exhibited significant positive correlations to increased SSTs, most evident at an 8 to 9-month lag. This study demonstrates that different tropical forest types exhibit asynchronous responses to seasonal and El Niño-driven drought, and suggests that mechanisms controlling dry forest leaf phenology are related to water-limitation, whereas rainforests are more light-limited.
Habitual Physical Activity in Mitochondrial Disease

Purpose Mitochondrial disease is the most common neuromuscular disease and has a profound impact upon daily life, disease and longevity. Exercise therapy has been shown to improve mitochondrial function in patients with mitochondrial disease. However, no information exists about the level of habitual physical activity of people with mitochondrial disease and its relationship with clinical phenotype. Methods Habitual physical activity, genotype and clinical presentations were assessed in 100 patients with mitochondrial disease. Comparisons were made with a control group individually matched by age, gender and BMI. Results Patients with mitochondrial disease had significantly lower levels of physical activity in comparison to matched people without mitochondrial disease (steps/day; 6883±3944 vs. 9924±4088, p = 0.001). 78% of the mitochondrial disease cohort did not achieve 10,000 steps per day and 48%were classified as overweight or obese. Mitochondrial disease was associated with less breaks in sedentary activity (Sedentary to Active Transitions, % per day; 13±0.03 vs. 14±0.03, p = 0.001) and an increase in sedentary bout duration (bout lengths / fraction of total sedentary time; 0.206±0.044 vs. 0.187±0.026, p = 0.001). After adjusting for covariates, higher physical activity was moderately associated with lower clinical disease burden (steps / day; rs = −0.49; 95% CI −0.33, −0.63, P<0.01). There were no systematic differences in physical activity between different genotypes mitochondrial disease. Conclusions These results demonstrate for the first time that low levels of physical activity are prominent in mitochondrial disease. Combined with a high prevalence of obesity, physical activity may constitute a significant and potentially modifiable risk factor in mitochondrial disease.
The Relationship between Diet Breadth and Geographic Range Size in the Butterfly Subfamily Nymphalinae – A Study of Global Scale

The “oscillation hypothesis” has been proposed as a general explanation for the exceptional diversification of herbivorous insect species. The hypothesis states that speciation rates are elevated through repeated correlated changes – oscillations – in degree of host plant specificity and geographic range. The aim of this study is to test one of the predictions from the oscillation hypothesis: a positive correlation between diet breadth (number of host plants used) and geographic range size, using the globally distributed butterfly subfamily Nymphalinae. Data on diet breadth and global geographic range were collected for 182 Nymphalinae butterflies species and the size of the geographic range was measured using a GIS. We tested both diet breadth and geographic range size for phylogenetic signal to see if species are independent of each other with respect to these characters. As this test gave inconclusive results, data was analysed both using cross-species comparisons and taking phylogeny into account using generalised estimating equations as applied in the APE package in R. Irrespective of which method was used, we found a significant positive correlation between diet breadth and geographic range size. These results are consistent for two different measures of diet breadth and removal of outliers. We conclude that the global range sizes of Nymphalinae butterflies are correlated to diet breadth. That is, butterflies that feed on a large number of host plants tend to have larger geographic ranges than do butterflies that feed on fewer plants. These results lend support for an important step in the oscillation hypothesis of plant-driven diversification, in that it can provide the necessary fuel for future population fragmentation and speciation.
Secure Image Retrieval Based on Visual Content and Watermarking Protocol

As an interesting application on cloud computing, content-based image retrieval (CBIR) has attracted a lot of attention, but the focus of previous research work was mainly on improving the retrieval performance rather than addressing security issues such as copyrights and user privacy. With an increase of security attacks in the computer networks, these security issues become critical for CBIR systems. In this paper, we propose a novel two-party watermarking protocol that can resolve the issues regarding user rights and privacy. Unlike the previously published protocols, our protocol does not require the existence of a trusted party. It exhibits three useful features: security against partial watermark removal, security in watermark verification and non-repudiation. In addition, we report an empirical research of CBIR with the security mechanism. The experimental results show that the proposed protocol is practicable and the retrieval performance will not be affected by watermarking query images.
FA-Stack: A Fast Array-Based Stack with Wait-Free Progress Guarantee

The prevalence of multicore processors necessitates the design of efficient concurrent data structures. Shared concurrent stacks are widely used as inter-thread communication structures in parallel applications. Wait-free stacks can ensure that each thread completes operations on them in a finite number of steps. This characteristic is valuable for parallel applications and operating systems, especially in real-time environments. Unfortunately, because wait-free algorithms are typically hard to design and considered inefficient, practical wait-free stacks are rare. In this paper, we present a practical, fast array-based concurrent stack with wait-free progress guarantee, named FA-Stack. A series of optimizations are proposed to bound the number of steps required to complete every push and pop operation. In addition, FA-Stack adopts a time-stamped scheme to reclaim memory. We use <italic>linearizability </italic>, a correctness condition for concurrent data structures, to prove that FA-Stack is a wait-free linearizable stack with respect to the <italic>Last in First Out</italic> (LIFO) semantics. Our evaluation with representative benchmarks shows that FA-Stack is an efficient wait-free stack. For example, compared to Sim-Stack (a state-of-the-art wait-free stack), FA-Stack improves the throughput of <italic>halfhalf</italic> benchmark by up to 2.4<inline-formula> <tex-math notation="LaTeX">$\times$</tex-math><alternatives><inline-graphic xlink:href="peng-ieq1-2770121.gif"/> </alternatives></inline-formula>.
Examining Perseveration in Three-Year-Olds Using the Go/No-Go Task

Perseveration, or responding in a previously relevant way that is no longer appropriate, has been traditionally studied in the context of the Dimensional Change Card Sort task (Zelazo, 2006). This study uses a modified version of the Go/No-Go task, which controls for spatial location of the test cards and perceptual conflict of the display, to examine perseveration. Three-year-old children were found to perseverate in the dimensional switch condition; they could not flexibly modify responding behavior and continued to respond to stimuli when no longer appropriate. Children did not perseverate in the nondimensional switch condition. These findings suggest that perceptual conflict and spatial location associations are not necessary for perseveration errors.
Response of Cultured Neuronal Network Activity After High-Intensity Power Frequency Magnetic Field Exposure

High-intensity and low frequency (1–100 kHz) time-varying electromagnetic fields stimulate the human body through excitation of the nervous system. In power frequency range (50/60 Hz), a frequency-dependent threshold of the external electric field-induced neuronal modulation in cultured neuronal networks was used as one of the biological indicator in international guidelines; however, the threshold of the magnetic field-induced neuronal modulation has not been elucidated. In this study, we exposed rat brain-derived neuronal networks to a high-intensity power frequency magnetic field (hPF-MF), and evaluated the modulation of synchronized bursting activity using a multi-electrode array (MEA)-based extracellular recording technique. As a result of short-term hPF-MF exposure (50–400 mT root-mean-square (rms), 50 Hz, sinusoidal wave, 6 s), the synchronized bursting activity was increased in the 400 mT-exposed group. On the other hand, no change was observed in the 50–200 mT-exposed groups. In order to clarify the mechanisms of the 400 mT hPF-MF exposure-induced neuronal response, we evaluated it after blocking inhibitory synapses using bicuculline methiodide (BMI); subsequently, increase in bursting activity was observed with BMI application, and the response of 400 mT hPF-MF exposure disappeared. Therefore, it was suggested that the response of hPF-MF exposure was involved in the inhibitory input. Next, we screened the inhibitory pacemaker-like neuronal activity which showed autonomous 4–10 Hz firing with CNQX and D-AP5 application, and it was confirmed that the activity was reduced after 400 mT hPF-MF exposure. Comparison of these experimental results with estimated values of the induced electric field (E-field) in the culture medium revealed that the change in synchronized bursting activity occurred over 0.3 V/m, which was equivalent to the findings of a previous study that used the external electric fields. In addition, the results suggested that the potentiation of neuronal activity after 400 mT hPF-MF exposure was related to the depression of autonomous activity of pacemaker-like neurons. Our results indicated that the synchronized bursting activity was increased by hPF-MF exposure (E-field: >0.3 V/m), and the response was due to reduced inhibitory pacemaker-like neuronal activity.
Odin (ANKS1A) Modulates EGF Receptor Recycling and Stability

The ANKS1A gene product, also known as Odin, was first identified as a tyrosine-phosphorylated component of the epidermal growth factor receptor network. Here we show that Odin functions as an effector of EGFR recycling. In EGF-stimulated HEK293 cells tyrosine phosphorylation of Odin was induced prior to EGFR internalization and independent of EGFR-to-ERK signaling. Over-expression of Odin increased EGF-induced EGFR trafficking to recycling endosomes and recycling back to the cell surface, and decreased trafficking to lysosomes and degradation. Conversely, Odin knockdown in both HEK293 and the non-small cell lung carcinoma line RVH6849, which expresses roughly 10-fold more EGF receptors than HEK293, caused decreased EGFR recycling and accelerated trafficking to the lysosome and degradation. By governing the endocytic fate of internalized receptors, Odin may provide a layer of regulation that enables cells to contend with receptor cell densities and ligand concentration gradients that are physiologically and pathologically highly variable.
The transcription factors Runx3 and ThPOK cross-regulate acquisition of cytotoxic function by human Th1 lymphocytes

Cytotoxic CD4 (CD4CTX) T cells are emerging as an important component of antiviral and antitumor immunity, but the molecular basis of their development remains poorly understood. In the context of human cytomegalovirus infection, a significant proportion of CD4 T cells displays cytotoxic functions. We observed that the transcriptional program of these cells was enriched in CD8 T cell lineage genes despite the absence of ThPOK downregulation. We further show that establishment of CD4CTX-specific transcriptional and epigenetic programs occurred in a stepwise fashion along the Th1-differentiation pathway. In vitro, prolonged activation of naive CD4 T cells in presence of Th1 polarizing cytokines led to the acquisition of perforin-dependent cytotoxic activity. This process was dependent on the Th1 transcription factor Runx3 and was limited by the sustained expression of ThPOK. This work elucidates the molecular program of human CD4CTX T cells and identifies potential targets for immunotherapy against viral infections and cancer.
The Association between Aids Related Stigma and Major Depressive Disorder among HIV-Positive Individuals in Uganda

Background Major depressive disorder in people living with HIV/AIDS (PLWHA) is common and may be associated with a number of factors, including AIDS-related stigma, decreased CD4 levels, increased opportunistic infections and sociodemographic variables. The extent to which AIDS-related stigma is associated with major depressive disorder among PLWHA has not been well studied in sub-Saharan Africa. The objective of this study was to examine the associations between major depressive disorder, AIDS-related stigma, immune status, and sociodemographic variables with the aim of making recommendations that can guide clinicians. Methods We assessed 368 PLWHA for major depressive disorder, as well as for potentially associated factors, including AIDS-related stigma, CD4 levels, presence of opportunistic infections, and sociodemographic variables. Results The prevalence of major depressive disorder was 17.4%, while 7.9% of the participants had AIDS related stigma. At multivariable analysis, major depressive disorder was significantly associated with AIDS-related stigma [OR = 1.65, CI (1.20–2.26)], a CD4 count of ≥200 [OR 0.52 CI (0.27–0.99)], and being of younger age [0.95, CI (0.92–0.98). Conclusions Due to the high burden of major depressive disorder, and its association with AIDS related stigma, routine screening of PLWHA for both conditions is recommended. However, more research is required to understand this association.
Homologs of PROTEIN TARGETING TO STARCH Control Starch Granule Initiation in Arabidopsis Leaves[OPEN]

Two plastidial coiled coil-containing proteins play a critical role in delivering suitable maltooligosaccharide primers to STARCH SYNTHASE4 during starch granule initiation. The molecular mechanism that initiates the synthesis of starch granules is poorly understood. Here, we discovered two plastidial proteins involved in granule initiation in Arabidopsis thaliana leaves. Both contain coiled coils and a family-48 carbohydrate binding module (CBM48) and are homologs of the PROTEIN TARGETING TO STARCH (PTST) protein; thus, we named them PTST2 and PTST3. Chloroplasts in mesophyll cells typically contain five to seven granules, but remarkably, most chloroplasts in ptst2 mutants contained zero or one large granule. Chloroplasts in ptst3 had a slight reduction in granule number compared with the wild type, while those of the ptst2 ptst3 double mutant contained even fewer granules than ptst2. The ptst2 granules were larger but similar in morphology to wild-type granules, but those of the double mutant had an aberrant morphology. Immunoprecipitation showed that PTST2 interacts with STARCH SYNTHASE4 (SS4), which influences granule initiation and morphology. Overexpression of PTST2 resulted in chloroplasts containing many small granules, an effect that was dependent on the presence of SS4. Furthermore, isothermal titration calorimetry revealed that the CBM48 domain of PTST2, which is essential for its function, interacts with long maltooligosaccharides. We propose that PTST2 and PTST3 are critical during granule initiation, as they bind and deliver suitable maltooligosaccharide primers to SS4.
Evaluation of oil degradation process using the combined system of thermal analysis and infrared spectroscopic analysis

To evaluate the oxidative stability and coking deposit tendency, the thermal analysis method such as thermogravimetry and differential thermal analysis (TG-DTA) is thought to be suitable comparing with the usual isothermal bulk test. Considering the evaluation method of properties for liquid lubricants using TG-DTA, the process of oil degradation during TG-DTA should be clarify. In this paper, its process was analyzed using the combined system of TG-DTA and IR (infrared spectroscopy). As a result, it was found that its process depended on the lubricant type and atmosphere. Also, the temperatures where the oxidation, carbonaization and ashesization occur were cleared for a variety of lubricants. In addition, the index of the oxidative stability and coking tendency in the TG-DTA was considered.
Impact of hematogones on the long-term outcomes of single-unit cord blood transplantation for adult patients

Abstract Hematogones are normal B-lymphocyte precursors identified in the regenerative state of the bone marrow following allogeneic hematopoietic stem cell transplantation (HSCT). To evaluate the impact of hematogones on long-term outcomes after single-unit cord blood transplantation (CBT), we retrospectively analyzed 134 adult patients at our institute. At the median time of 41 days (range, 20 to 77 days) after CBT, the median proportion of morphological hematogones in bone marrow was found to be 2.4% (range, 0 to 13.0%). In the patients with standard-risk, the higher proportion of morphological hematogones was associated with lower transplant-related mortality (TRM) after CBT. The proportion of hematogones did not affect the subsequent absolute lymphocyte counts in the peripheral blood and serum immunoglobulin G levels six months later after CBT. These data shows that morphological hematogones in the routine bone marrow analysis might be a practical and easily evaluable method of predicting outcomes after CBT.
