Abstract
The thermally conductive phase change materials (PCMs) were produced using the crosslinked Poly (Styrene-block-Ethylene Glycol Di Methyl Methacrylate) (PS-PEG DM) copolymer by employing the boron nitride (BN)/lead oxide (PbO) nanoparticles. DSC and TGA methods were used to research the phase transition temperatures (melting and crystallization temperatures: Tm and Tc), the phase change enthalpies (melting and crystallization enthalpies: ∆Hm and ∆Hc). The thermal conductivities (λ) of the PS-PEG/BN/PbO PCM nanocomposites were investigated. The ∆Hm and λ value of PS-PEG/BN/PbO PCM nanocomposite containing BN 13 wt%, PbO 60.90 wt%, and PS-PEG 26.10 wt% was determined to be 27.6 Jg− 1 and 18.874 W/(mK). From DSC measurements, Tm and Tc of PS-PEG PCM nanocomposites were found to vary between 57.8°C-205°C, 4.7°C-188.6°C, respectively. The crystallization fraction (Fc) values of PS-PEG (1000) and PS-PEG (1500) copolymers are 0.032–0.034; 0.063, respectively. XRD results of the polymers, the PCM nanocomposites showed that the sharp diffraction peaks at 17.00° and 25.28° of PS-PEG copolymer belonged to the PEG part. When nanoparticles were added to the polymers, SEM and TEM images confirmed that the PCM nanocomposites have a grain, spherical shape, and homogeneous distribution of the nanoparticles. Since these new nanocomposites, whose successful results we have presented as radiation shields in another study, show remarkable thermal conductivity performance, they can be used as conductive polymer nanocomposites for effective heat dissipation in heat exchangers, power electronics, electric motors, generators, communication, and lighting equipment. At the same time, according to our results, PCM nanocomposites can be considered as heat storage materials in the energy storage system.

Abstract
It is unclear whether endovascular therapy (ET) can improve the prognosis of posterior circulation progressive ischemic stroke (PIS) due to large vessel stenosis/occlusion. The purpose of this study was to evaluate the efficacy and safety of ET for patients with PIS in posterior circulation who were selected based on ischemic penumbra detected on brain imaging. According to inclusion and exclusion criteria, patients with posterior circulation PIS hospitalized in the Second Affiliated Hospital of Nanchang University from May 2020 to December 2021 were retrospectively included and divided into ET + standard medical therapy (SMT) and SMT according to actual treatment conditions. Our research shows that ET is more effective than conservative therapy of Progressive Ischemic Stroke in Posterior Circulation with Large Artery Stenosis/Occlusion. In those patients with high NIHSS scores, ET had better neurological function recovery than conservative treatment. Delayed recanalization still has better therapeutic effect.

Published: August 2022

Abstract
Purpose
To explore the biomechanical effect and mechanism of cannulated compression screw in the treatment of non traumatic necrosis of femoral head with allogeneic fibula graft.
Methods
Based on the CT data of healthy adults, four groups of models were established by using finite element software: the normal group, the femoral head necrosis group, the hip preservation operation group with allogeneic fibula graft (later referred to as group A), and the hollow compression screw combined with allogeneic fibula graft (later referred to as group B). Apply 1440N, 2400N and 4200N loads to the four groups of models respectively, observe the changes of stress distribution on the surface and deep of the femoral head, internal mechanical transmission pathway in different groups under different loads, as well as the displacement of implants in the two groups of surgical models, and explore the biomechanical role and mechanism of hollow compression screws in the same kind of allogeneic fibula graft.
Results
(1) Under normal circumstances, the pressure of the femoral head surface and internal cancellous bone is mainly concentrated in the anterolateral weight-bearing area of the femoral head, and the internal stress can be well transmitted to the lower limbs through the femoral calcar, femoral neck and other parts, without obvious stress conduction barrier.(2) The closer the necrotic location is to the anterolateral column of the weight-bearing area, the stress peaks of the cartilage, cortical bone and cancellous bone on the surface of the femoral head increase significantly compared with the normal model. With the increase of load, the stress peaks of the above bones increase significantly. In type C1 and C2 necrosis, the stress transmission of femoral head and neck was abnormal, and the stress concentration occurred in the normal bone around the necrotic area.(3) Under different loads, the peak value of von Mises stress in type C1 necrotic area in group B decreased by 1.67mpa (-18.45%), 2.77mpa (-18.37%), 4.84mpa (-18.35%) respectively compared with group A. the peak value of von Mises stress in type C2 necrotic area in group B decreased by 0.05Mpa (-0.58%), 0.08mpa (-0.56%), 0.15Mpa (-0.6%) respectively compared with group A; At the same time, under different loads, the displacement distance of type C1 allogeneic fibula strips in group B decreased by 0.06mm (-8.7%), 0.1mm (-8.7%) and 0.17mm (-8.42%) respectively compared with group A. the displacement distance of type C2 allogeneic fibula strips in group B decreased by 0.01mm (-1.72%), 0.01mm (-1.03%) and 0.02mm (-1.19%) respectively compared with group A.
Conclusion
In the allogeneic fibula graft surgery, the addition of cannulated screws may have a better mechanical effect of dispersing the stress in the necrotic area and stabilizing the fibula strip, which is most significant in type C1 necrosis.
Infants’ Nutrition in Polygynous Family Structure: Evidence from SSA Countries
Authors: Efobi Uchenna 
Published: August 2022

Abstract
Considering the mounting interest concerning the effect of family structures on child wellbeing, the present paper investigates whether polygyny affects a child’s nutrition in Africa. To this end, I utilize nationally representative data from twenty-seven SSA countries for the periods 2010 to 2020 to examine the effects of polygynous household structure on a broad set of indicators of child nutrition intake, including dietary diversity and specific micronutrient intake. By relying on the gender of the first and second child of the first wife, I attempt to control for the endogeneity of polygyny in the estimation. The empirical results consistently indicate less dietary intake of the child in such a household. The effect is seemingly driven by the level of education of the mother and within-household social interaction. Some of the adverse effects of polygyny are only seen for the child in poorer homes. Suggesting both economic and normative channels as the plausible mechanism through which polygyny affects a child’s nutritional quality.

Published: August 2022

Abstract

Purpose: To improve cover crops as rotational partners, intraspecies variation for cover cropping traits such as nutrient mobilization, carbon deposition, and beneficial microbial recruitment must be identified. The majority of research on cover crops has focused on interspecies comparisons for cover cropping variation with minimal research investigating intraspecies variation. Methods: To address if variation of cover cropping traits is present within a cover cropping species, we grew 15 diverse accessions (four modern cultivars, three landraces, eight wild accessions) of pea in an organic setting. We measured various cover cropping traits such as nutrient mobilization, soil organic matter deposition, microbial recruitment, and quantified the effect of pea accession on the growth and yield of a subsequently planted corn crop. Results: We found that domestication history and genotype of pea had a significant effect on soil properties: C%, N%, manganese, magnesium, sodium, calcium, and effective CEC, and the yield of the subsequent corn crop. Additionally, no variation for prokaryotic recruitment (alpha and beta diversity) was observed within pea, however we did observe significant variation for fungal recruitment (alpha and beta diversity) due to domestication and accession. In conclusion, our results revealed the presence of intraspecies variation for cover cropping traits which, may have impacted the rotational values of pea accessions. Conclusions: Our results demonstrate that cover crops can be improved as rotational partners to ultimately boost crop yields in sustainable agroecosystems.

HDSAP: Heterogeneity-aware dynamic scheduling algorithm to improve performance of nano-scale many-Core processors for unpredictable workloads
Authors: Kia Keihaneh , Rajabzadeh Amir 
Published: August 2022

Abstract
The performance growth in processors has been continuing toward increasing the number of processing cores on the chip and scaling the feature size of transistors. However, in the nano era, side effects of the scaling, such as induced heterogeneities in the performance, power, and soft error rate of identically designed cores, prevent the potential performance from being fully utilized. In this paper, we harness the mentioned side effects in shared-memory multicore processors with unpredictable workloads by a dynamic heuristic scheduling algorithm called HDSAP. The aim of HDSAP is to maximize performance, i.e. the average response time, under power and reliability constraints in presence of induced heterogeneities. In this regard, we use a mathematical model to quantify task to core assignments based on performance variation. We also consider the variation in power to change selected cores when the power constraint is missed. To meet the reliability constraint, we use N-Modular redundancy while being aware of the variation in soft error rate of cores to prevent under/over reliability estimation. To evaluate HDSAP, we run SPLASH benchmark suite on Sniper and MACPat simulators. As a result, the response time of HDSAP reduces by 6%, 8%, and 25% in comparison with similar algorithms under the same power and reliability constraints.

Published: August 2022

Abstract
Regional multi energy system (RMES)has advantages in meeting the diversified needs of energy and improving energy efficiency. In this paper, with the increase of DC power sources such as photovoltaic power generation and fuel cells, it is difficult for batteries to fully improve energy utilization efficiency and solve the problem of large-scale consumption of clean energy power. An adiabatic compressed air energy storage (A-CAES) device is established, and RMES model considering integrated demand response (IDR) is considered. As the most potential energy storage device at present, A-CAES device can better promote the absorption of new energy such as wind energy and photovoltaic, effectively utilize traditional energy and reduce the environmental pollution caused by RMES. Improve the ”multi-energy complementary” energy supply mode adopted by RMES through A-CAES. IDR is adopted to improve the economy and flexibility of integrated energy system. The results show that the total operating cost of the model established in this paper is significantly reduced, which is effective and feasible to promote new energy consumption, energy conservation and emission reduction.

Published: August 2022

Abstract
P-Element-induced wimpy testis (PIWI) proteins are engaged in epigenetic regulation of gene expression in germline cells when they are in combination with PIWI-interacting RNA (piRNA). Different types of tumour cells have been found to exhibit abnormal expression of piRNA and PIWI proteins. HCC is majorly diagnosed in later stages, which is associated with lower survival rates. There is an urgent need for improved, more specific and less invasive diagnostic methods that can detect earlier stages of the disease. Purpose: The aim of this study was to assess the diagnostic potential by determining the expression profiles of PIWI-like protein-1, -2, -3, & -4 (PIWIL1, PIWIL2, PIWIL3, & PIWIL4) in hepatocellular carcinoma, and determine its association with clinicopathological features. Methods: Samples from patients comprising serum and frozen fragments of paired tissue specimens (tumour and adjacent non-malignant liver tissue) were employed for molecular analyses. Real-time polymerase chain reaction was performed on 50 tissue and serum samples from HCC patients and 25 serum samples from healthy controls. Results: The PIWIL1, PIWIL2, PIWIL3, & PIWIL4 levels were significantly (<0.001) higher in both HCC tissue and serum samples than in the controls. Additionally, the diagnostic performance was assessed by ROC curves, the PIWIL1-4 levels in serum showed better potential and sensitivity to screen HCC patients than their levels in tissues. Moreover, some PIWIL elements were found here to be significantly correlated with the HCC profile. Conclusion: PIWI expression is considered as a powerful non-invasive diagnostic tool for HCC. Our findings also support the theory that PIWIL expression is critical for cancer progression.

Published: August 2022

Abstract
Bckgoround:Treating the relapsed or refractory Classical Hodgkin Lymphomas were still challenging, previous studies indicated they can benefit from immune checkpoint inhibitors, over expression of PD-L1 can also be predictive marker for anti -PD -1 therapeutic efficacy, however, harmonization with different IHC assay s and explanation of the PD -L1 immunostaining results remains controversial in CHL. In this study, we sought to optimize the PD-L1 Immunohistochemistry (IHC) assay in classical Hodgkin lymphoma (CHL). Methods: All tests were performed on tumor tissue microarray established from 54 CHLs. Three IHC assays (405.9A11, SP142, 22C3) for PD-L1 expression were compared semi-quantitatively with RNAscope assay (No. 310035, ACD), and the difference for their expression on background immune cells (ICs), their associations with densities of TIL/TAM makers and their implication on survival were also analyzed. Results: 405.9A11 assay demonstrated best specificity on HRS cells and sensitivity on ICs. Thus, positive expression of PD-L1 was more frequent on ICs (85.2%) than on HRS cells (48.1%). Different subgroups of background IC cells including tumor associated macrophages (TAMs) were assessed and scored by CD4, CD8, FOXP3, and CD163. PD-L1 expression on ICs were most associated with elevated densities of TAMs, and in concordance with TAMs(P=0.026), PD-L1 expression on ICs ( P=0.067)indicated a negative effect on survival.Conclusions: 405.9A11 assay was proved to be most convincible for demonstrating PD-L1 expression，pathologists should report PD-L1 expression in a combined manner including both positive status of HRS cells and positive percentage of ICs.

Published: August 2022

Abstract
The phrase "anomaly detection" is often used to refer to any technique that seeks to find samples that differ from expected patterns. Depending on the availability of data labels, the types of abnormalities, and the applications, many anomaly detection models are developed. This study aims to give a well-organized and thorough review of anomaly detection research. We think it will aid in a superior thoughtful of the various areas in which study has been conducted on this issue, as well as how approaches created in one field can be utilized in domains where they were not originally intended. We've divided the anomaly detection research methodologies into distinct categories. We describe the fundamental anomaly detection approach, as well as its modifications and important assumptions, for distinguishing between normal and abnormal behavior in each category. In addition, we highlight the merits and limits of each category, as well as examine the computational complexity of the approaches in real-world application areas. Finally, we discuss research gaps and limitations encountered when using deep anomaly detection algorithms to solve real-world problems.

Abstract
Superconducting materials have extremely high application value in our life. At present, the discovery of new superconducting materials relies on the experience of experts through a large number of "trial and error" experiments. Obtaining the properties of superconductors also requires a large number of experiments. In this paper, we propose to use the XGBoost model to identify superconductors, reaching 0.986 in accuracy. We apply the deep forest algorithm to predict the critical temperature of superconductors and the coefficient of determination reaches 0.944. We propose to apply the same algorithm to predict the forbidden band width of materials and the coefficient of determination reaches 0.917. A new sub-network structure is constructed to predict the Fermi level of materials and the coefficient of determination reaches 0.984. All of these algorithms have state-of-the-art performance. Finally, the model is tested with a publicly available dataset to identify 50 candidate superconducting materials with a critical temperature greater than 90K.
Quality of Life in multiple scenarios: The impact of work mode and social contact quantity
Authors: Leng Cheng-Han , Tsai Chi-Shiun , Chan Ta-Chien , Lee Hsuan-Wei 
Published: August 2022

Abstract
Background This study aims to explore issues, such as (i) whether there is a difference in quality of life (QoL) among subgroups of the work mode (working from home (WFH) vs. working in the office (WIO)), social contact quantity, and face contact ratio; (ii) whether employees' QoL is moderated by the social contact quantity and face contact ratio given their work mode; (iii) whether the three-way interaction effect of work mode, social contact quantity, and face contact ratio on employee's QoL is significant; and (iv) whether the WHOQOL-BREF invariantly measures for the subgroups of the work mode, social contact quantity, and face contact ratio. Methods We assessed the QoL of 803 WFH employees and 588 WIO employees during the same time period and divided them into sixteen groups resulting from the levels of work mode, social contact quantity, and face contact ratio, forming a case-control study. A differential item functioning (DIF) analysis was used for analyzing the responses on the WHOQOL-BREF under the 4-dimensional rating scale model fitting. Results Our results indicated that WFH employees’ QoL was superior to that of WIO employees [χ2(1) = 8.52, p = 0.0035]. However, since the work mode was moderated by the social contact quantity [χ2(3) = 10.89, p = .012] and face contact ratio [χ2(1) = 11.39, p < .001], WFH employees’ QoL was worse than that of WIO employees if their amount of social contact was low and if most social contacts were not face-to-face. Moreover, WFH employees’ QoL was better than WIF employees’ QoL when most contacts were not face-to-face and the number of social contacts was high [χ2(3) = 9.07, p = .028]. Besides, the WHOQOL-BREF measured employees’ QoL biasedly as many facets of the WHOQOL-BREF were found to diverge among subgroups of the work mode and social contact quantity.Conclusions The WFH mode was practical in the COVID-19 pandemic. However, maintaining social connections is equally important so that employees can maintain good performance in jobs. The facets detected as DIF items provided implications for QoL research methodology and insight into factors affecting employees' QoL.
