Multi-Channel Weight-Sharing Autoencoder Based on Cascade Multi-Head Attention for Multimodal Emotion Recognition

Multimodal Emotion Recognition is challenging because of the heterogeneity gap among different modalities. Due to the powerful ability of feature abstraction, Deep Neural Networks (DNNs) have exhibited significant success in bridging the heterogeneity gap in cross-modal retrieval and generation tasks. In this work, a DNNs-based Multi-channel Weight-sharing Autoencoder with Cascade Multi-head Attention (MCWSA-CMHA) is proposed to generically address the affective heterogeneity gap in MER. Specifically, multimodal heterogeneity features are extracted by multiple independent encoders, and then a scalable heterogeneous feature fusion module (CMHA) is realized by connecting multiple multi-head attention modules in series. The core of the proposed algorithm is to reduce the heterogeneity between the output features of different encoders through the unsupervised training of MCWSA, and then to model the affective interactions between different modal features through the supervised training of CMHA. Experimental results demonstrate that the proposed MCWSA-CMHA achieves outperformance on two publicly available datasets compared with the state-of-the-art techniques. In addition, visualization experiments and approximation experiments are used to verify the effectiveness of each module in the proposed algorithm, and the experimental results show that the proposed MCWSA-CMHA can mine more emotion-related information among multimodal features compared with other fusion methods.
Diagnosis of Severity Degree for Power Transformer Oil-pressboard Insulation Surface Discharge

It is very important to determine the severity degree for power transformer oil-pressboard insulation surface discharge.To research the diagnosis method of severity degree for power transformer oil-pressboard insulation surface discharge based on ultra high frequency(UHF) signal and dissolved gases analysis(DGA) in oil,a surface discharge simulation and test equipment and measurement system were set up in laboratory,which consisted of surface discharge model,test tank,UHF sensor,Zhongfen 2000A gas-phase chromatographic instrument,and DST-4 partial discharge detector.Moreover,surface discharge growth from inception to breakdown was simulated,in which test voltage was increased step-by-step,and ultra high frequency signal and dissolved gases in oil were measured in the growth process.Finally,a diagnosis method of severity degree for power transformer oil-pressboard insulation surface discharge was put forward according to the regular pattern of ultra high frequency signal and dissolved gases in oil.The results show that severity degree of surface discharge can be divided into three stages: inception stage,growth stage,and critical stage according to statistics spectrum of the ultra high frequency signal;ultra high frequency signal and dissolved gases in oil both can indicate the oil-pressboard surface discharge severity degree,however,dissolved gases analysis method is not as sensitive as ultra high frequency method;C2H2/total hydrocarbon generated by oil-pressboard surface discharge is more than 10%;C2H2/total hydrocarbon can act as the rule to determine the severity degree of power transformer oil-pressboard insulation surface discharge,and surface discharge is in critical stage when the C2H2/total hydrocarbon value increases rapidly.
Clinical utility of new parameters provided by XE-2100 RET channel

Multiple parameter automated hematology analyzer XE2100 (Sysmex Corporation, hereinafter called "XE2100") has a channel intended to determine the count of reticulocytes automatically (RET Channel). In recent years, new clinical parameters were developed using this channel, and several studies have reported the clinical utility of them. In this article, we introduce the fragmented red cell quantification system (RET master) for which we involved in the development, as well as the experience to use and the usefulness of the immature platelet fraction counting system (IPF master) that was released recently.
How South African Families Protected Themselves during the COVID-19 Pandemic: A Qualitative Study

The World Health Organization (WHO) reported a cluster of cases of ‘viral pneumonia’—‘Coronavirus Disease 2019’ (COVID-19)—in Wuhan City, the People’s Republic of China on 31 December 2019. To curb the spread of the virus, various containment measures were introduced. However, no study has explored how families protected themselves during the pandemic. Therefore, this study explored how families protected themselves during the COVID-19 pandemic using a qualitative exploratory design. Thirty-one adult participants, representing families in the Western Cape province of South Africa, were virtually interviewed. The sampling approach was both convenient and snowball. The data were analysed using thematic analysis. The results show that families followed and adapted to the mainstream protection measures as implemented by the South African government but in addition believed that adherence to non-pharmaceutical interventions would protect them from contracting the virus. Therefore, the government and other stakeholders should support families in making it easier to protect themselves during the current and future pandemic(s).
The Effect of Cu2O Synthesis Method on its Optical Properties

Cuprous Oxide (Cu2O) is a semiconductor material with excellent photocatalytic properties, a broad range of applications, low fabrication costs, and is non-toxic. We concentrated on the impact of two different synthesis methods in this study. Cu2O synthesis was carried out using two different techniques, which are chemical deposition and hot-soap method. The chemical deposition (CD) method used a copper sulfate pentahydrate precursor in a room temperature reaction. Hot-soap (HS) method employed copper acetylacetonate with reaction at higher temperature. The X-Ray Diffraction analysis reveals a sharp peak with a size of 53.8 nm and a broaden peak with a size of 26.24 nm for particles synthesized by (Cu2O-CD) and (Cu2O-HS), respectively. Using the Tauc Plot method, the band gap of Cu2O-HS is estimated to be 2.65 eV and that of Cu2O-CD to be 1.7 eV. Cu2O-HS emits a noticeable photoluminescence peak at 425 nm, whereas Cu2O-CD emits no peaks in photoluminescence spectra analysis. These findings indicate that Cu2O-HS has a high potential for use in photocatalytic mechanisms.
Earnings Management and Audit Quality: Evidence from Malaysia

This paper aims at investigating the relationship of audit market share, industry specialisation and Big 4 towards earnings management. The research posits that audit market share and industry specialisation constrains earnings management. In addition, it hypothesized a positive relationship between Big 4 and earnings management. The data was gathered from Data Stream, Thomson Reuters to test the research hypotheses. Out of 1488 companies-years observation between 2015 to 2018, the results indicate that there is no significant difference between audit market share and industry specialist auditors in constraining earnings management. In addition, findings support that Big 4 was significantly higher when specialists conducted the audit. The results provide empirical evidence consistent with the hypothesis that auditor with big size improves audit quality.
Preparation and in vitro characterization of electrospun scaffolds composed of chitosan, gelatin and 58S bioactive glass nanoparticles for skin tissue engineering

Background and aims: The presence of an appropriate scaffold at the wound site could significantly improve the healing process. In this study, we aimed to prepare a biomimetic nanocomposite scaffold composed of chitosan, gelatin, and 58S bioglass nanoparticles for skin tissue engineering. Methods: The nanocomposite scaffolds composed of chitosan, gelatin, and 58S bioglass nanoparticles were fabricated through electrospinning process. Then the cell viability assay was performed in order to evaluate the biological properties of the membranes. The optimum concentration of bioglass nanoparticles was determined for further studies. In vitro characterization was also performed to evaluate physicochemical properties of the scaffolds. Results: The chitosan/gelatin scaffold containing 2% of 58S bioglass nanoparticles showed no cell toxicity, and the dermal fibroblasts were found capable of proliferation on the membrane. The in vitro results obtained from the scanning electron microscopy (SEM), attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), and porosity tests demonstrated the appropriate properties of the membrane as a scaffold for skin regeneration. Conclusions: It was concluded that a chitosan-gelatin membrane containing 2% of 58S bioglass nanoparticles had the potential to function as a scaffold to accelerate wound healing due to its suitable properties, such as high porosity, high surface/volume ratio, and excellent biocompatibility.
Exploring Farm Anaerobic Digester Economic Viability in a Time of Policy Change in the UK

The combination of a post-Brexit agricultural policy, the Global Methane Pledge announced during the last United Nations Climate Change Conference in Glasgow (COP26), and urgency of meeting climate goals means the UK has a unique opportunity to create an exemplar through recognition of the benefits of small-scale farm anaerobic digesters that valorise on-site wastes for renewable electricity and heat, cushioning agri-businesses against energy perturbations. To explore economic viability of farm-based biogas production, combinations of support levels, energy prices, capital cost, internal rate of return (IRR), and digestate value were analysed, employing a 550-cow dairy farm with access to other agricultural wastes. A 145 kWe system utilising 100% of CHP electricity (grid value: £0.1361 per kWh) and 70% of the heat (heating oil value: £0.055 per kWh) could achieve an IRR above 15.5% with a median electricity tariff of £0.1104 per kWh at a heat tariff from £0.0309 to £0.0873 per kWh thermal. Under a subsidy-free regime, the same system could achieve a 10% IRR with electricity prices in the range £0.149 to £0.261 per kWh. High fertiliser prices could increase digestate value, further improving viability. With late-2021 high energy prices, the technology approaches subsidy-free viability, but uptake is unlikely unless wider environmental and societal benefits of on-farm systems can be explicitly valued.
Children’s Perception and Utilization of ECEC Physical Environments

Early childhood education and care (ECEC) institutions play an important role in many young children’s lives. Child-oriented research about the role of the physical ECEC environment in children’s play is scarce. The present study aims to develop knowledge about what children consider crucial elements in the physical ECEC environment. Seventy-one children (3–6 years old) were interviewed to gain insight into their perspectives on the physical ECEC environment. This study indicates that children desire a physical ECEC environment with various affordances supporting different play possibilities and that the social context influences how children may interact with the physical environment. The design of the physical ECEC environment is crucial to children’s everyday play experiences while in care.
Can Sustainable Development Save Mangroves?

The Earth is warming, ecosystems are being overexploited, oceans are being polluted, and thousands of species are going extinct—all fueled by the need for a permanent increase in production for more consumerism and development. “Business as usual” continues untouched, while increasing attention has been given to the “sustainable development” concept. Despite their importance as life supporting ecosystems, forests, oceans, and wetlands are being destroyed at an accelerating rate. The conservation and restoration of mangroves, for example, are also vital for the planet to face catastrophic global warming. Based on a non-systematic literature review, we address how true mangrove conservation is incompatible with so-called “sustainable development”. We turn to the urgent changes needed to avoid environmental and societal collapse, promoted by the Western economic development paradigm, and address why the sustainable development approach has failed to stop environmental degradation and protect resources for next generations. Proposed solutions involve the rejection of the capital-oriented, nature-predatory systems, degrowth, a deep transformation of our energy matrix, and a shift in our nutrition to lower levels of the food chain. These are based on a profound sense of responsibility over the planet, respecting all life forms, ecosystem dynamics, and life sustaining properties of the biosphere.

Incidence and Predictors of Permanent Pacemaker Implantation after Transcatheter Aortic Valve Procedures: Data of The Netherlands Heart Registration (NHR)

Atrioventricular conduction disturbance leading to permanent pacemaker (PM) implantation is a frequent and relevant complication after transcatheter aortic valve implantation (TAVI). We aimed to evaluate the rate of post-TAVI permanent PM implantation over time and to identify the predictive factors for post-TAVI PM. The data were retrospectively collected by the Netherlands Heart Registration (NHR). In total, 7489 isolated TAVI patients between 2013 and 2019 were included in the final analysis. The primary endpoint was a permanent PM implantation within 30 days following TAVI. The incidence of the primary endpoint was 12%. Post-TAVI PM showed a stable rate over time. Using multivariable logistic regression analysis, age (OR 1.01, 95% CI 1.00–1.02), weight (OR 1.00, 95% CI 1.00–1.01), creatinine serum level (OR 1.15, 95% CI 1.01–1.31), transfemoral TAVI approach (OR 1.34, 95% CI 1.11–1.61), and TAVI post-dilatation (OR 1.58, 95% CI 1.33–1.89) were shown to be independent predictors of PM. Male sex (OR 0.80, 95% CI 0.68–0.93) and previous aortic valve surgery (OR 0.42, 95% CI 0.26–0.69) had a protective effect on post-TAVI PM. From a large national TAVI registry, some clinical and procedural factors have been identified as promoting or preventing post-TAVI PM. Further efforts are required to identify high-risk patients for post-TAVI PM and to reduce the incidence of this important issue.
Chalcogen Bonding in the Molecular Dimers of WCh2 (Ch = S, Se, Te): On the Basic Understanding of the Local Interfacial and Interlayer Bonding Environment in 2D Layered Tungsten Dichalcogenides

Layered two-dimensional transition metal dichalcogenides and their heterostructures are of current interest, owing to the diversity of their applications in many areas of materials nanoscience and technologies. With this in mind, we have examined the three molecular dimers of the tungsten dichalcogenide series, (WCh2)2 (Ch = S, Se, Te), using density functional theory to provide insight into which interactions, and their specific characteristics, are responsible for the interfacial/interlayer region in the room temperature 2H phase of WCh2 crystals. Our calculations at various levels of theory suggested that the Te···Te chalcogen bonding in (WTe2)2 is weak, whereas the Se···Se and S···S bonding interactions in (WSe2)2 and (WS2)2, respectively, are of the van der Waals type. The presence and character of Ch···Ch chalcogen bonding interactions in the dimers of (WCh2)2 are examined with a number of theoretical approaches and discussed, including charge-density-based approaches, such as the quantum theory of atoms in molecules, interaction region indicator, independent gradient model, and reduced density gradient non-covalent index approaches. The charge-density-based topological features are shown to be concordant with the results that originate from the extrema of potential on the electrostatic surfaces of WCh2 monomers. A natural bond orbital analysis has enabled us to suggest a number of weak hyperconjugative charge transfer interactions between the interacting monomers that are responsible for the geometry of the (WCh2)2 dimers at equilibrium. In addition to other features, we demonstrate that there is no so-called van der Waals gap between the monolayers in two-dimensional layered transition metal tungsten dichalcogenides, which are gapless, and that the (WCh2)2 dimers may be prototypes for a basic understanding of the physical chemistry of the chemical bonding environments associated with the local interfacial/interlayer regions in layered 2H-WCh2 nanoscale systems.
From pattern to process? Dual travelling waves, with contrasting propagation speeds, best describe a self‐organised spatio‐temporal pattern in population growth of a cyclic rodent

Abstract The dynamics of cyclic populations distributed in space result from the relative strength of synchronising influences and the limited dispersal of destabilising factors (activators and inhibitors), known to cause multi‐annual population cycles. However, while each of these have been well studied in isolation, there is limited empirical evidence of how the processes of synchronisation and activation–inhibition act together, largely owing to the scarcity of datasets with sufficient spatial and temporal scale and resolution. We assessed a variety of models that could be underlying the spatio‐temporal pattern, designed to capture both theoretical and empirical understandings of travelling waves using large‐scale (>35,000 km2), multi‐year (2011–2017) field monitoring data on abundances of common vole (Microtus arvalis), a cyclic agricultural rodent pest. We found most support for a pattern formed from the summation of two radial travelling waves with contrasting speeds that together describe population growth rates across the region.
Study of Planetary Boundary Layer, Air Pollution, Air Quality Models and Aerosol Transport Using Ceilometers in New South Wales (NSW), Australia

The planetary boundary layer height (PBLH) is one of the key factors in influencing the dispersion of the air pollutants in the troposphere and, hence, the air pollutant concentration on ground level. For this reason, accurate air pollutant concentration depends on the performance of PBLH prediction. Recently, ceilometers, a lidar instrument to measure cloud base height, have been used by atmospheric scientists and air pollution control authorities to determine the mixing level height (MLH) in improving forecasting and understanding the evolution of aerosol layers above ground at a site. In this study, ceilometer data at an urban (Lidcombe) and a rural (Merriwa) location in New South Wales, Australia, were used to investigate the relationship of air pollutant surface concentrations and surface meteorological variables with MLH, to validate the PBLH prediction from two air quality models (CCAM-CTM and WRF-CMAQ), as well as to understand the aerosol transport from sources to the receptor point at Merriwa for the three case studies where high PM10 concentration was detected in each of the three days. The results showed that surface ozone and temperature had a positive correlation with MLH, while relative humidity had negative correlation. For other pollutants (PM10, PM2.5, NO2), no clear results were obtained, and the correlation depended on the site and regional emission characteristics. The results also showed that the PBLH prediction by the two air quality models corresponded reasonably well with the observed ceilometer data and the cause and source of high PM10 concentration at Merriwa can be found by using ceilometer MLH data to corroborate back trajectory analysis of the transport of aerosols to the receptor point at Merriwa. Of the three case studies, one had aerosol sources from the north and north west of Merriwa in remote NSW, where windblown dust is the main source, and the other two had sources from the south and south east of Merriwa, where anthropogenic sources dominate.

Different Green Manures (Vicia villosa and Brassica juncea) Construct Different Fungal Structures, Including Plant-Growth-Promoting Effects, after Incorporation into the Soil

The application of green manure to soil improves soil health by increasing biological activity. However, little attention has been paid to the effects of different green manures on the microbiological community and soil function after incorporation. Here, it was found that the green manures of Vicia villosa (leguminous) and Brassica juncea (non-leguminous) have different fungal structures, despite the soil originally being the same. Moreover, some isolated strains showed plant-growth-promoting abilities. Three strains (H1: Penicillium spp., H2: Clonostachys spp., and H3: Trichoderma spp.) from leguminous-manure-incorporated soil and four strains (B1: Purpureocillium spp., B4: Taifanglania spp., B6: Trichoderma spp., and B10: Aspergillus spp.) from non-leguminous-manure-incorporated soil showed the potential for plant growth enhancement. Plant-growth-promoting traits revealed that four strains possessed phosphate solubilization and siderophore production, although none of them showed the ability to produce indole-3-acetic acid (IAA)-like compounds with/without tryptophan. In addition, higher extracellular enzyme activities—including endoglucanase and β-glucosidase activities—were also detected in the soil-incorporated green manures. In conclusion, this study suggests that different fungal structures appeared when different green manures were applied, which promoted plant growth. This indicates the potential benefits of promoting the incorporation of green manure into the soil.
