One for “All”: a unified model for fine-grained sentiment analysis under three tasks

Background Fine-grained sentiment analysis is used to interpret consumers’ sentiments, from their written comments, towards specific entities on specific aspects. Previous researchers have introduced three main tasks in this field (ABSA, TABSA, MEABSA), covering all kinds of social media data (e.g., review specific, questions and answers, and community-based). In this paper, we identify and address two common challenges encountered in these three tasks, including the low-resource problem and the sentiment polarity bias. Methods We propose a unified model called PEA by integrating data augmentation methodology with the pre-trained language model, which is suitable for all the ABSA, TABSA and MEABSA tasks. Two data augmentation methods, which are entity replacement and dual noise injection, are introduced to solve both challenges at the same time. An ensemble method is also introduced to incorporate the results of the basic RNN-based and BERT-based models. Results PEA shows significant improvements on all three fine-grained sentiment analysis tasks when compared with state-of-the-art models. It also achieves comparable results with what the baseline models obtain while using only 20% of their training data, which demonstrates its extraordinary performance under extreme low-resource conditions.
Investigation of hydrogen-sensing properties of Pd/AlGaAs-based Schottky diodes

The hydrogen response characteristics and sensing properties or catalytic Pd/Al/sub 0.3/Ga/sub 0.7/As metal-oxide-semiconductor (MOS) and metal-semiconductor (MS) Schottky diodes are systematically studied. The effects of hydrogen adsorption on device performances such as the current-voltage characteristics, sensitivity, barrier height variation, heat of adsorption, and transient response are investigated. The studied devices can be operated under very wide hydrogen concentration regimes with remarkable hydrogen-sensing properties. Particularly, at an extremely low hydrogen concentration of 15 ppm H/sub 2//air, both steady-state and transient responses at room temperature can be detected. In addition, under the presence of oxide layer in the studied MOS device, a larger change of barrier height and higher hydrogen response are observed. In addition, according to the van't Hoff equation, the initial values of heat adsorption for Pd/semiconductor and Pd/oxide interface are calculated as 7.29 and 49.6 KJ/mole, respectively.
The Influence of Atmosphere‐Ocean Phenomenon on Water Availability Across Temperate Australia

Links between climate variability modes, rainfall, and streamflow are important for understanding the trajectories of change and dynamics in water availability. In this study, we examined the influence of the El Nino Southern Oscillation, Indian Ocean Dipole, Southern Annular Mode, and Interdecadal Pacific Oscillation modes on interannual variations in rainfall and streamflow in four hydroclimate regions. We also explored the link between climate variability modes and extreme rainfall and streamflow years. Climate mode indices, rainfall, and streamflow data from 1975 to 2018 were analyzed for 92 predominately forested catchments located across temperate Australia. Climate modes had divergent influences on streamflow and rainfall between and within regions. Across temperate Australia, a higher proportion of interannual variation in rainfall was explained by climate modes than for streamflow, indicating factors other than atmosphere‐ocean phenomena are important in determining interannual streamflow variability. Extremes in rainfall and streamflow across regions were related to the co‐occurrence of climate modes, with a stronger relationship between teleconnections and low rainfall/streamflow years than high rainfall/streamflow years. The study provides new insights into the regional drivers of hydrological extremes and consolidates our understanding of the role of teleconnections on water availability in the temperate zone of Australia.
Application of simple examination and retrieval procedure in evolutionary algorithms for feeder reconfiguration

This paper presents an effective approach based on simple examination and retrieval procedure (SERP) that can be used in evolutionary algorithms, such as genetic algorithm (GA) and binary particle swarm optimization (BPSO), for solving distribution feeder reconfiguration problems. The proposed approach is able to improve the search efficiency by identifying and modifying the illegal chromosomes that represent switching operation plans. The concept of simple examination is done by checking the numbers of normally opened switches on a branchless line segment in distribution systems. By applying the proposed approach, the number of illegal chromosomes during the regeneration process in evolutionary algorithms can be reduced. The idea of retrieval procedure is done by trying to use the information from historical local optimal solutions to repair the illegal chromosomes as many as possible. A 33-Bus distribution system and a practical distribution system of Taiwan Power Company (TPC) are used in this paper to verify and validate the effectiveness of the proposed procedure. The simulations consider the distribution system with and without distributed generation (DG) for power losses problems. Simulation results show that integration of the proposed procedure to GA and PSO provides more efficient and stable solutions for feeder reconfiguration problems.

Composite effects of reflections and ground bounce for signal line through a split power plane

The signal propagating along a microstrip line over a slot on the power plane will suffer from composite effects of reflected noise by a discontinuity in signal return path and ground bounce between power/ground planes. A new equivalent circuit model is proposed and simulations are performed for a three-layer structure to characterize ground bounce coupling.
A Method to Characterize the Quality of a Polymer Laser Sintering Process

The reproducibility and reliability of quality aspects are an important challenge of the polymer laser sintering process. However, existing quality concepts and standardization activities considering influencing factors along the whole process chain have not been validated experimentally yet. In this work, these factors are analyzed and kept constant to obtain a reliable material data set for different layer thicknesses and testing temperatures. In addition, material qualities regarding powder ageing effects are analyzed using different build heights and layer thicknesses: while an increase of the layer thickness reduces mechanical part strength and density, it also results in a less intense thermal ageing of unmolten powder due to shorter build times.
Tourism and rural income inequality: empirical evidence for China

ABSTRACT This article uses the mediating effect model to explore tourism’s impact on rural income inequality and the underlying mechanism. For the first time, this article calculates the province-level rural Gini coefficients and Theil indexes to measure rural income inequality based on the income survey data of rural China. The results show that total tourism, domestic tourism and inbound tourism are all driving forces for increasing rural income inequality. The effects of total tourism and domestic tourism are statistically significant. Moreover, tourism significantly influences rural development represented by employment, education, income and consumption. Rural development significantly mediates tourism’s effects on rural income inequality. The effects of tourism on rural income inequality vary significantly across different rural development levels. This article also proposes a series of targeted policy implications, which can better serve China's sustainable tourism and rural development.

A Hazard Analysis of Three Silage Storage Methods for Dairy Cattle

Objectives: The study objective was to characterize work methods, hazards and annual hazard exposure hours of three silage storage methods. Methods: A telephone questionnaire was designed and administered to 24 Wisconsin dairy managers. The exposure durations reported were scaled to a standard-sized dairy herd with equal dry matter tons of silage stored and fed each year. Results: Managers reported no silo gas hazards with either bunker or bag silos. Compared to tower silos, managers reported reduced fall hazards with bunker silos and no fall hazards with bag silos although both introduced front end loader operation injury hazards. Compared to bunkers, managers who used bag silos reported no exposure to tractor overturns. Conclusions: Although some hazards are clearly present using any ensling method, dairy farms that adopt silage bag technology can reduce many of the hazards traditionally associated with silage work.
Design of the First Chinese 1 MW Solar-Power Tower Demonstration Plant

This article presents thermodynamic performance of a solar-power tower plant, DAHAN, which is constructed in Beijing as the first Chinese solar-power tower demonstration plant. Different from the existing solar-power tower plant, the DAHAN configuration includes a two-stage thermal-energy storage system consisting of a high-temperature oil accumulator and a low-temperature steam accumulator. The sensible heat and latent heat of steam are stored in the high- and low-temperature accumulators, respectively. The new plant is designed in such a way that during the operation the receiver can be connected to a steam turbine or energy-storage system. Software that simulates the performance of the plant has been developed and the thermodynamic performance of the plant was investigated. The results show that the annual thermal efficiency from solar to power of the plant can reach 8.35%. The annual efficiency of plant can be increased by 0.65 percentage points at the optimal condition. The results provide a better understanding for the design and operation of solar-power tower plant.
Summer-time thermal comfort in vernacular earth dwellings in Yazd, Iran

There is widespread assumption that vernacular earth dwellings in hot climates, particularly those in central Iran are climate-responsive and provide thermal comfort in hot periods even without the aid of electro-mechanical cooling systems. The paper describes two surveys undertaken to investigate the provision of comfortable indoor temperatures in vernacular central-courtyard earth dwellings in Yazd in hot seasons. Firstly, a thermal comfort survey established the comfort temperature for the residents of vernacular dwellings during hot summer days in Yazd. Secondly, the diversity of temperatures that could be found within different spaces of typical vernacular dwellings on typical summer days was investigated by measuring and recording the temperature variations. Recorded temperatures were afterwards compared with the comfort temperature (zone) obtained from the thermal comfort survey in order to discover whether indoor temperatures fall inside (or outside) the comfort zone. This showed to what extent and vernacular passively-cooled houses could provide comfortable indoor temperatures.
Pass it on?: Retweeting in mass emergency

We examine microblogged information generated during two different co-occurring natural hazards events in Spring 2009. Due to its rapid and widespread adoption, microblogging in emergency response is a place for serious consideration and experimentation for future application. Because microblogging is comprised of a set of practices shaped by a number of forces, it is important to measure and describe the diffuse, multi-party information exchange behaviors to anticipate how emergency governance might best play a role. Here we direct consideration toward information propagation properties in the Twitterverse, describing features of information redistribution related to the retweet (RT @) convention. Our analysis shows that during an emergency, for tweets authored by local users and tweets that contain emergency-related search terms, retweets are more likely than non-retweets to be about the event. We note that users are more likely to retweet information originally distributed through Twitter accounts run by media, especially the local media, and traditional service organizations. Comparing local users to the broader audience, we also find that tweet-based information redistribution is different for those who are local to an emergency event.
The Sagittal Integral Morphotype in Male and Female Rowers

The goal of this study was to describe the integrated spinal assessment of the sagittal morphotype in rowers to determine whether the intense practice of rowing causes a modification of the sagittal curvatures of the spine, its relationship with the rowing technique, and training background. The second goal was to analyse how the dorsal and lumbar curves behave in the three phases of the rowing gesture, and to determine which phases can be detrimental to the correct development of the spine during growth. We analysed the spine curvatures in the sagittal plane of 29 females and 82 males, which were measured with an inclinometer in standing, slump sitting, maximal trunk flexion and during rowing performance. The average value of thoracic kyphosis in the rowers was 30° (mean, 30 + 8.27°). Thoracic hyperkyphosis was found in only two rowers (1.8%). Lumbar lordosis was within normal range in 84.1% of the males (mean, 27 + 9.57°) and 75.9% of female rowers (mean, 33°). Functional thoracic hyperkyphosis was observed in 57.4% of the males and 17.1% of the females. Functional lumbar hyperkyphosis was observed in 28 of the 69 males (40.5%) and five of 22 females (17.2%). Rowing seems to provide adequate spine alignment in the sagittal plane on standing. The integrated spinal assessment of the sagittal morphotype showed that half or our rowers presented with functional thoracic hyperkyphosis, and 43.2% presented with functional lumbar hyperkyphosis. Spine behaviour during the rowing technique shows that the thoracic kyphosis (98.2%) and lumbar spine (91%) perform within normative ranges and could explain the adequate positioning of the spine in the sagittal plane on standing. Years of rowing training tend to reduce thoracic kyphosis in males.
High-dose versus low-dose prednisolone in symptomatic patients with post-COVID-19 diffuse parenchymal lung abnormalities: an open-label, randomised trial (the COLDSTER trial)

In some patients, respiratory symptoms and imaging abnormalities persist after acute coronavirus disease 2019 (COVID-19) pneumonia [1–3]. Chest computed tomography (CT) scans generally show diffuse parenchymal lung abnormalities consistent with organising pneumonia [4]. It has been proposed that the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could act as a trigger to exalt the presence of pre-existing interstitial lung abnormalities encountered in the general population, especially in smokers. Previous observational studies reported improvement with glucocorticoids in symptomatic patients with post-COVID-19 diffuse parenchymal lung abnormalities (PC-DPLAS) [4–6]. A recent guideline recommended glucocorticoids for treating PC-DPLAS [3]. However, there are no randomised controlled trials on therapies for this condition. High-dose prednisolone may not be superior to a low-dose 6-week regimen in improving clinical, physiological and radiological outcomes, or health-related quality of life, in patients with symptomatic post-COVID-19 diffuse parenchymal lung abnormalities https://bit.ly/32zqnXt
Noise pollution at school environment located in residential area

Noise pollution around the educational area can negatively affect the performance of both teachers and students. The noise level should be around the range of 35 dBA to 55 dBA in the school area. Little attention has been given by individuals or government concerning noise pollution in schools' surrounding. A study of this problem is presented in this paper by doing some measurement on the noise level at schools located in residential areas case study at Sekolah Kebangsaan Sri Skudai, Sekolah Kebangsaan Taman Universiti IV and Sekolah Menengah Taman Universiti has been conducted to measure noise level in its surrounding. The results from this study shows that the rate of noise level in Sekolah Kebangsaan Sri Skudai is very high and not suitable for schools' environment.
Damage Detection in Flat Panels by Guided Waves Based Artificial Neural Network Trained through Finite Element Method

Artificial Neural Networks (ANNs) have rapidly emerged as a promising tool to solve damage identification and localization problem, according to a Structural Health Monitoring approach. Finite Element (FE) Analysis can be extremely helpful, especially for reducing the laborious experimental campaign costs for the ANN development and training phases. The aim of the present work is to propose a guided wave-based ANN, developed through the use of the Finite Element Method, to determine the position of damages. The paper first addresses the development and assessment of the modeling technique. The FE model accuracy was proven through the comparison of the predicted results with experimental and analytical data. Then, the ANN was developed and trained on an aluminum plate and subsequently verified in a composite plate, as well as under different damage configurations. According to the results herein proposed, the ANN allowed to detect and localize damages with a high level of accuracy in all cases of study.
Thermoelastic damping in bilayered micromechanical beam resonators

A detailed analysis of thermoelastic damping (TED) is essential in the design of the next generation of layered composite microresonators employed in microelectromechanical systems (MEMS) for sensing and communications. Here, we present an exact theory to compute the frequency dependence of thermoelastic damping in asymmetric, bilayered, micromechanical Euler–Bernoulli beam resonators. Comparison of the computed values for thermoelastic damping with previously measured internal friction in Au/SiO2 microcantilevers suggests that TED contributes significantly to damping at higher modes and frequencies (∼1 MHz), but is negligible at lower frequencies, in these structures. The utility of the theory for MEMS design is illustrated by considering the representative example of Al/SiC bilayered microresonators.
Gems of the southern Japanese seas – four new species of Edwardsianthus (Anthozoa, Actiniaria, Edwardsiidae) with redescriptions of two species

﻿Abstract Edwardsianthus England, 1987 is a genus of Edwardsiidae, a family of burrowing and worm-like sea anemones characterized by lacking four mesenteries in the first cycle and containing only one type of nematocysts in nemathybomes. Until now, this genus has accommodated only two species since its establishment and has been recorded only from Indo-West Pacific regions. In this study, six species are reported from Japan: two are previously known species, E.pudicus (Klunzinger, 1877) and E.gilbertensis (Carlgren, 1931); four are new species, E.carbunculussp. nov., E.sapphirussp. nov., E.smaragdussp. nov., and E.amethystussp. nov. Based on these results, the diagnostic features of the genus are revised.
Adjuvant Palbociclib for Early Breast Cancer: The PALLAS Trial Results (ABCSG-42/AFT-05/BIG-14-03)

PURPOSE Palbociclib is a cyclin-dependent kinase 4 and 6 inhibitor approved for advanced breast cancer. In the adjuvant setting, the potential value of adding palbociclib to endocrine therapy for hormone receptor–positive breast cancer has not been confirmed. PATIENTS AND METHODS In the prospective, randomized, phase III PALLAS trial, patients with hormone receptor–positive, human epidermal growth factor receptor 2–negative early breast cancer were randomly assigned to receive 2 years of palbociclib (125 mg orally once daily, days 1-21 of a 28-day cycle) with adjuvant endocrine therapy or adjuvant endocrine therapy alone (for at least 5 years). The primary end point of the study was invasive disease-free survival (iDFS); secondary end points were invasive breast cancer–free survival, distant recurrence-free survival, locoregional cancer-free survival, and overall survival. RESULTS Among 5,796 patients enrolled at 406 centers in 21 countries worldwide over 3 years, 5,761 were included in the intention-to-treat population. At the final protocol-defined analysis, at a median follow-up of 31 months, iDFS events occurred in 253 of 2,884 (8.8%) patients who received palbociclib plus endocrine therapy and in 263 of 2,877 (9.1%) patients who received endocrine therapy alone, with similar results between the two treatment groups (iDFS at 4 years: 84.2% v 84.5%; hazard ratio, 0.96; CI, 0.81 to 1.14; P = .65). No significant differences were observed for secondary time-to-event end points, and subgroup analyses did not show any differences by subgroup. There were no new safety signals for palbociclib in this trial. CONCLUSION At this final analysis of the PALLAS trial, the addition of adjuvant palbociclib to standard endocrine therapy did not improve outcomes over endocrine therapy alone in patients with early hormone receptor–positive breast cancer. Despite its sobering result, PALLAS is a role model collaboration of caregivers in 21 countries around the globe
