Research on Performance Test System of Space Harmonic Reducer in High Vacuum and Low Temperature Environment

The harmonic reducer, with its advantages of high precision, low noise, light weight, and high speed ratio, has been widely used in aerospace solar wing deployment mechanisms, antenna pointing mechanisms, robot joints, and other precision transmission fields. Accurately predicting the performance of the harmonic reducer under various application conditions is of great significance to the high reliability and long life of the harmonic reducer. In this paper, a set of automatic harmonic reducer performance test systems is designed. By using the CANOpen bus interface to control the servo motor as the drive motor, through accurately controlling the motor speed and rotation angle, collecting the angle, torque, and current in real time, the life cycle test of space harmonic reducer was carried out in high vacuum and low temperature environment on the ground. Then, the collected data were automatically analyzed and calculated. The test data of the transmission accuracy, backlash, and transmission efficiency of the space harmonic reducer were obtained. It is proven by experiments that the performance data of the harmonic reducer in space work can be more accurately obtained by using the test system mentioned in this paper, which is convenient for further research on related lubricating materials.

Ailanthone Enhances Gastric Cancer Cell Apoptosis Through Inducing DNA Damage and Repressing Base Excision Repair Via Downregulating P23

Background: Chemotherapy plays an irreplaceable role in the treatment of gastric cancer (GC), but currently available chemotherapeutic drugs are not ideal. Medicinal plants are an important direction for new drug discovery. Methods: We combined literature collection, organoid drug screening and PDX verification to search for new, effective drugs. The effect of AIL on the GC cells was investigated by CCK-8 assays, Colony Formation Assay and Cell Viability, Cell migration and invasion assay and PDX mice model. The expression of indicated RNA and proteins were measured by qRT-PCR ,IHC and western blotting. The proteins HSP90 binding to P23 or XRCC1 were identified by Co-IP. Results: Through drug screening of GC organoids, we had determined that ailanthone (AIL) has an anticancer effect on GC cells in vitro and in vivo. We also found that AIL promoted apoptosis of GC cells through flow cytometry analysis and the expression of caspase 3 and H2AX were significantly enhanced by AIL in GC cells and tumor tissues, suggesting that AIL can induce DNA damage and apoptosis of GC cells. Further transcriptome sequencing of the PDX tissue indicated that AIL inhibited the expression of XRCC1 which plays an important role in DNA damage repair, and the results were also confirmed by western blotting. In addition, we found that AIL inhibited the expression of P23 and inhibition of P23 decreased the expression of XRCC1 through western blotting analysis, indicating that AIL can regulate XRCC1 via P23. The results of co-immunoprecipitation showed that AIL can inhibit the binding of P23 and XRCC1 to HSP90 respectively.Conclusion: These findings indicate that AIL can induce DNA damage and apoptosis of GC cells. Meanwhile, AIL can decrease XRCC1 by downregulating P23 to inhibit DNA damage repair. The present study shed light to the new drug isolated from natural medicinal plants for GC therapy.
Towards Bengali Word Embedding: Corpus Creation, Intrinsic and Extrinsic Evaluations

Distributional word vector representation orword embedding has become an essential ingredient in many natural language processing (NLP) tasks such as machine translation, document classification, information retrieval andquestion answering. Investigation of embedding model helps to reduce the feature space and improves textual semantic as well as syntactic relations.This paper presents three embedding techniques (such as Word2Vec, GloVe, and FastText) with different hyperparameters implemented on a Bengali corpusconsists of180 million words. The performance of the embedding techniques is evaluated with extrinsic and intrinsic ways. Extrinsic performance evaluated by text classification, which achieved a maximum of 96.48% accuracy. Intrinsic performance evaluatedby word similarity (e.g., semantic, syntactic and relatedness) and analogy tasks. The maximum Pearson (ˆr) correlation accuracy of 60.66% (Ssˆr) achieved for semantic similarities and 71.64% (Syˆr) for syntactic similarities whereas the relatedness obtained 79.80% (Rsˆr). The semantic word analogy tasks achieved 44.00% of accuracy while syntactic word analogy tasks obtained 36.00%
The middle Smithian (Early Triassic) ammonoid Arctoceras blomstrandi: conch morphology and ornamentation in relation to stratigraphy

The ammonoid genus Arctoceras (Hyatt) occurs across all palaeolatitudes, and is a key genus for middle Smithian biostratigraphical correlations globally. In this study, intraspecific variations in conch morphology, ornamentation and allometry are examined in relation to stratigraphic position. Arctoceras is the most abundant ammonoid genus in the middle Smithian of Svalbard. Originally, seven Arctoceras species were described from Svalbard. Later, as the importance of intraspecific variation was recognized, six of the Arctoceras species from Svalbard were treated as junior synonyms of Arctoceras blomstrandi (Lindström). Yet, the variations in A. blomstrandi conch morphology remain poorly quantified and the dependence on stratigraphic position, unknown. We quantify the intraspecific variation in conch morphology, ornamentation and allometry in relation to stratigraphy of the Svalbard Arctoceras. The results support the assignment of all Arctoceras morphotypes from Svalbard to a single species A. blomstrandi. The new data allow for an updated species description and open the way for the use in biostratigraphy of the endmember morphology A. blomstrandi var. costatus. We document consistent changes in conch morphology and ornamentation in the studied stratigraphic interval, with a distinct shift towards more evolute and ornate conchs in the top of the interval. The trends in the strength of ornamentation are partly explained by covariation with conch morphology (Buckman's law). The most marked shift in the conch morphology and allometric development of A. blomstrandi coincides with the onset of the positive carbon isotope excursion at the end of the middle Smithian, but pre‐dates the mid–late Smithian cooling of the sea surface.
Kinetics of α -glucosidase inhibitory activity and phytochemical analysis of Piper crocatum Ruiz & Pav. leaves ethanol extract

α-Glucosidase is an enzymes group that playing essential roles in the digestion of polysaccharide. Inhibitor of a-glucosidase can decrease polysaccharide digestion rate and therefore plays a significant function in preventing the development of diabetes (type 2). Piper crocatum Ruiz & Pav. is an essential herb applied traditionally in Indonesia to treat diabetes mellitus. This work evaluated the a-glucosidase inhibitory activity of P. crocatum leaves ethanol extract. Phytochemical component of the extract was also analyzed. The α-glucosidase inhibitory activity of the P. crocatum leaves ethanol extract was examined by reacting its different concentrations with α-glucosidase and p-nitrophenyl glucopyranoside. Kinetics of the α-glucosidase inhibition was determined using a Lineweaver-Burke plot. Phytochemical in the extract was determined using GC-MS. Ethanol extract of P. crocatum leaves exhibited moderate α-glucosidase inhibitory activity compared with acarbose. Phytochemical analyses showed the presence of stilbene, linolenic acid, phenol, phytosteroid, and α-tocopherol. The competitive action of P. crocatum leaves ethanol extract is due to its inhibitory effects on α-glucosidase. The stilbene and phenol compounds indicated responsible for anti-diabetic activity from P. crocatum leaves ethanol extract.
What Do Palaeo-Anthropologists Believe About the Disappearance of Neanderthals?

The causes of Neanderthal disappearance about 40,000 years ago remain highly contested. Over a dozen serious hypotheses are currently endorsed to explain this enigmatic event. Given the relatively large number of contending explanations and the relatively large number of participants in the debate, it is unclear how strongly each contender is supported by the research community. What does the community actually believe about the demise of Neanderthals? To address this question, we conducted a survey among practicing palaeo-anthropologists (total number of respondents = 216). It appears that received wisdom is that demography was the principal cause of the demise of Neanderthals. In contrast, there is no received wisdom about the role that environmental factors and competition with modern humans played in the extinction process; the research community is deeply divided about these issues. Finally, we tested the hypothesis that palaeo-anthropologists’ stand in the debate co-varies with their socio-political views and attitudes. We found no evidence for such a correlation.
Diabetes Distress, Depressive Symptoms and Type 2 Diabetes Management and Glycemic Control: The Mediating Role of Self-E�cacy

Background Diabetes distress has been distinguished from depressive symptoms in the linkages to type 2 diabetes management and glycemic control. There are few evidences in rural China untangled the underlying pathways among them. The aim of our study was to examine whether self-e�cacy reduced the detrimental effects of psychological variables on diabetes outcomes such as self-care behaviors, glycemic control and health-related quality of life (HRQoL). Methods 1574 adults diagnosed with type 2 diabetes from 31 rural clinics in China were assessed for psychological variables, self-management and HRQoL. Hemoglobin A1c (HbA1c) data at 6 months after the survey were extracted from electronic medical records. Hierarchical regression model examined independent effects of psychological variables, self-e�cacy on diabetes outcomes. KHB method and bootstrapping con�dence intervals were employed to test the mediating effect of self-e�cacy. Results Hierarchical regression analysis showed both diabetes distress and depressive symptoms were signi�cantly related to diet and HRQoL, but not related to glycemic control and medication adherence. Depressive symptoms, but not diabetes distress, was directly associated with physical activity. Mediation analysis demonstrated self-e�cacy mediated the relationships of both diabetes distress and depressive symptoms on self-care behaviors, glycemic control and HRQoL. Self-e�cacy may contribute to better diabetes outcome by ameliorating the effects of diabetes distress and depressive symptoms. Patients with psychological conditions may need tailored intervention that enhance self-e�cacy to improve management. symptoms on diabetes self-management, glycemic control and overall quality of life in the same study among adults with type 2 diabetes from primary care settings in rural China. Based on the conceptual model, our analyses reveal three main �ndings. First, both diabetes distress and depressive symptoms are independently associated with diet and HRQoL, but not signi�cant direct associated with HbA1c and medication adherence. Physical activity is signi�cant affected by depressive symptoms, but not by diabetes distress. Second, self-e�cacy was signi�cant related to self-care behaviors, HbA1c and HRQoL. Third, self-e�cacy, as an independent mediator, signi�cantly mediates the effect of both diabetes distress and depressive symptoms on diabetes self-management, glycemic control and HRQoL. The �ndings help elucidate key underlying mechanisms and pathways linking psychological factors and behavioral health with diabetes outcomes.
An Effective Method for Cadmium Removal from Scallop By-product Enzymatic Hydrolysate

ABSTRACT An effective method to remove cadmium (Cd) from scallop by-product enzymatic hydrolysate (SBEH) was developed, and the Cd bonding sites were studied. Cation-exchange resin, anion-exchange resin, activated charcoal, and zeolite were tested. The result showed that strong acid polystyrene cation-exchange resin was the most suitable sorption material for the removal of Cd. The optimal conditions were as follows: SBEH concentration at 17.07 mg/mL, pH value at 4.92, and adsorption time with 11.73 min, while 4 g resin was added in 50 mL solution at 30°C. The experimentally measured removal rate was 95.38% under these conditions. The Cd element has an intense bonding pattern with macromolecules, and more than half of the Cd element exists as positively charged ion in the SBEH. The cation-exchange resin removed Cd by dumping the macromolecules associated with the Cd element. Infrared (IR) spectra suggested that the sulfate ester groups and carboxyl groups in the macromolecules were binding sites of the Cd element in SBEH. These results provide a useful method for Cd removal from SBEH that potentially can be used for industrial processing.
Exploration of data-driven midsole algorithm design based in biomechanics data and Voronoi 3D to digital manufacturing.

This study proposed the creation of an algorithm for the elaboration of a midsole customized by functionalparameters and generative systems, with production through digital manufacturing. The computationalresources used are the Rhinoceros® program and the Grasshopper® extension. The primitives are given in a". asc" format for the plantar pressure distribution test; the position of the insole sensors (.jpeg); 3D geometryof the midsole parameterized from the outline of a common insole. The developed algorithm operates byconverting midsole geometry (brep) into point cloud complemented with a point cloud based on the positionof the sensors and the remapped values of maximum pressure into integer numbers. Voronoi 3D componentcell structure is generated by the overlapping point clouds. Based on the incorporation of an external algorithm,it was possible to obtain an open cell mesh structure. The digital manufacturing of the geometry was testedthrough three-dimensional printing similar to the Fused Deposition Modeling (FDM) process in rigid lactic acid(PLA) and flexible thermoplastic polyurethane (TPU). It was observed in the model printed on flexible materialthat the increase in the density of cells in the regions of greater pressure contributes to the increase in localstiffness, which may imply the individualization of the functional requirements of footwear. Nine customizationpossibilities are presented by changing three different variables, related to the density of points of the basegeometry and the conversion of pressure values. The third variable was the thickness of the final structure as afunction of the volume scale and faces of the three-dimensional cells generated by the 3D Voronoi. It isconcluded that the import of real data from biomechanical testing for parametric modeling in Grasshopper®could contribute to the design of shoes individualized by the aesthetic and functional requirements of eachconsumer.

Aims: To perform the isolation, characterization and sequencing of the bacteriophages. To demonstrate that the bacteriophages can be used for biocontrol of different Salmonella enterica serovars. Original Research Article Pottker et al.; MRJI, 30(10): 93-105, 2020; Article no.MRJI. 64596 94 Study Design: This study was an experimental study. Place and Duration of Study: Bacteriology and Mycology Laboratory in the Veterinary Hospital at the Faculty of Agronomy and Veterinary Medicine of the University of Passo Fundo (FAMV/UPF), Biotechnology Center (CBiotec) of the Federal University of Paraíba (UFPB), Center for Microscopy and Microanalysis at the Faculty of Veterinary of the Federal University of Rio Grande do Sul (UFRGS), between January – September 2016. Methodology: Twelve Salmonella enterica serovars (S. Anatum, S. Agona, S. Brandenburg, S. Bredeney, S. Infantis, S. Lexington, S. Panama, S. Rissen, S. Schwarzengrund, S. Tennessee, S. Enteritidis ATCC 13076 and S. Typhimurium ATCC 14028) were selected to be the hosts. We isolate, purify, produce and determine the bacteriophage titers to verify the potential for lysis of these phages against the hosts. Having determined the action of the phages against the hosts, we performed the sequencing of the bacteriophages on the Illumina Mi-Seq platform and the morphology was performed by transmission electron microscopy (TEM). Results: We isolated, characterized and sequenced the genome of two new bacteriophages, Salmonella phage UPF_BP1, belonging to the family Podoviridae and Salmonella phage UPF_BP2, family Myoviridae. UPF_BP1 has lytic action against seven tested Salmonella enterica serovars, while UPF_BP2 has action against the twelve tested serovars. Conclusion: The two new bacteriophages have a lytic action against different Salmonella enterica serovars, feeding our expectations for the development of alternatives for the use of antimicrobials, being possible candidates for use as a biocontrol of Salmonella enterica in food, animals and the environment.
Evaluating the Influence of Resident Agencies’ Participation in Flood Management via Social Media, in Nigeria

Disaster management is conducted in multilevel and different stages. However, these different stages are tied together by the key infrastructural components of Information and Communication Technology (ICT) such as social media which is central to the effectual management of disaster through residents’ participation. Nevertheless, there has been limited access to information technologies that enhance quick recovery services, timely response, and effective dissemination of disaster-related information. Therefore, this study examined the influence of resident agencies’ participation in disaster management via the use of social media information planning and training possibilities (SMDPT) in Nigeria. The study used a survey questionnaire and stratified random sampling technique to collect 370 primary data from flood disaster management agencies in Ibadan, Nigeria. The collected data were analyzed using Partial Least Square - Structural Equation Modeling (PLS-SEM). The study found that social media information planning and training (SMDPT) had a positive influence on flood disaster preparedness (DPRE), disaster response (DRES), and disaster recovery (DREC). Therefore, the study concludes that social media has become an important tool for planning during an emergency situation. Hence, an important implication of this study to the environmental regulatory policymakers and emergency response agencies is to create more awareness on the usability and applicability of social media in providing credible information regarding disaster management.
Social protection intervention and agricultural participation in West Africa

This study contributes towards the achievement of the United Nations (UN) 2030 Sustainable Development Goal (SDG) 1.3 which is to ‘implement appropriate social protection for all to mitigate risk and vulnerability’ by examining how social protection interventions contribute to agricultural participation in 15 West African countries which are members of the Economic Community of West African States (ECOWAS). Data for the study were sourced from the World Bank Country Policy and Institutional Assessment (CPIA), World Development Indicators (WDI) and the World Governance Indicators (WGI) for the period 2005–2018. The study applied the generalised method of moments (GMM) to resolve the possible issue of endogeneity that may result from the pooled ordinary least squares (POLS) and fixed effects. Findings showed that social protection is a significant driver of agricultural participation. This is based on the fact that two social protection variables included in the model, social protecting ratings and policy for social inclusion, are positive and statistically significant in explaining the level of agricultural participation in ECOWAS. This implies that a percentage increase in the level of social protection ratings and policy for social inclusion may increase agricultural participation by about 7.36% and 3.94%, respectively. The study recommends that effective social protection policies and programmes should be designed to transform the agricultural sector in West Africa.
Crime prevention in a low-crime nation: an enquiry into Japanese bōhan initiatives

ABSTRACT Despite high public safety levels, crime prevention (bōhan) is a common concern in Japanese society. In the early-2000s, the Japanese government set out to “create a crime-resistant society”, giving rise to a flurry of crime prevention initiatives involving not only state institutions but also citizen volunteers and private companies. Between 2003 and 2008, the number of bōhan volunteers grew by over 1200% to 2.5 million citizens. In Japanese cities, neighbourhood patrols as well as bōhan posters and signs present frequent reminders of significant societal attention to crime and crime prevention. This paper asks why crime prevention gained so much traction in a relatively safe country. It sets out by identifying the responsibilisation of non-state actors and the incorporation of bōhan measures into the urban environment as core themes of contemporary Japanese crime prevention efforts. Based on an analysis of government and police documents as well as Japanese scholarship, it then discusses two factors that facilitated the spread of crime prevention initiatives in Japan in the mid-2000-2010s: current crime prevention campaigns as a continuation of national currents and governance strategies, and the versatility and adaptability of crime prevention ideas and initiatives. As an in-depth account of bōhan initiatives in contemporary Japan and their roots, this paper provides insights into the governance of deviance and the integration of crime deterrence and surveillance into everyday life in Japanese cities.
