Dietary Diversity and Nutrient Intake of Han and Dongxiang Smallholder Farmers in Poverty Areas of Northwest China

This study aimed to evaluate the status of dietary diversity and nutrient intake among Han and Dongxiang smallholder farmers in poor rural areas of northwest China. In this cross-sectional study, dietary intake was assessed in 499 smallholder farmers aged 18–75 years from two nationally designated impoverished counties in Gansu Province, China, using three consecutive 24 h dietary recalls. The dietary diversity score (DDS) and nutrient adequacy ratio (NAR) were adopted to assess dietary diversity and micronutrient adequacy, respectively. The mean DDS (range from 1 to 9) in participants was relatively low (3.81 ± 1.01). Consumption of grains was excessive, while consumption of vegetables, fruits, meat, beans, eggs, fish, and dairy was inadequate. The NAR values were higher in Han Chinese, with the exceptions of vitamin C, potassium, pyridoxine, and selenium (p < 0.05). For each nutrient, the high DDS group had a higher mean NAR (p < 0.05), except for pyridoxine. High household monthly income, being Han Chinese, high DDS, and being aged over 45 years were positively associated with mean adequacy ratio (MAR) of 14 micronutrients evaluated. Lack of dietary diversity and insufficient intake of essential micronutrients are public health concerns in northwest China. Nutrition education and other proper methods to address these issues are needed.
Comparison of Allogenic and Autogenic Implantations of Dedifferentiated Fat Cells On Monoclonal Antibody 1-22-3-Induced Glomerulonephritis in Rats

Background We established an adipogenic progenitor cell line derived from mature adipocytes and named these cells dedifferentiated fat (DFAT) cells, which have been shown to have characteristics very similar to those of mesenchymal stem cells (MSCs). The potential application of DFAT cells to support cell-based therapies for regenerative and immunosuppressive therapies has been suggested. The present study was designed to address beneficial ways that DFAT implantation can be used clinically as immunosuppressive therapy to treat immunological glomerulonephritis. Methods We evaluated distribution of DFAT cells after intravenous injection through the tail vein in Wistar rats. We examined effects of allogenic implantation of DFAT cells on BrdU incorporation into kidney from rats with monoclonal antibody (mAb) 1-22-3-induced glomerulonephritis. We compared effects of allogenic and autogenic implantations of DFAT cells on excretion of urinary protein, renal function, and glomerular and nephrotubular injuries in these rats, and serum levels of tumor necrosis factor-stimulated gene-6 (TSG-6), and expression of TSG-6 mRNA in kidney. Results The allogenic implantations of DFAT cells trapped in lung improved excretion of urinary protein and renal function, and significantly suppressed glomerular and nephrotubular injuries in the rats with mAb1-22-3-induced glomerulonephritis compared with the autogenic implantations. The allogenic implantation of DFAT cells increased serum levels of TSG-6 especially in mAb 1-22-3-induced glomerulonephritis and significantly increased the expression of TSG-6 mRNA in kidney compared to the autogenic implantation. Conclusion These findings suggest that allogenic implantation of DFAT cells could be clinically useful immunosuppressive therapy for immunological glomerulonephritis.
A Review of Machine Translation Tools: The Translation’s Ability

The objective of the research is to review the ability of online machine translator tools includes Google Translate (GT), Collin Translator (CT), Bing Translator (BT), Yandex Translator (YT), Systran Translate (ST), and IBM Translator (IT). This research applies descriptive qualitative. The documentation was used in this study. The result of the analysis shows that the translation results are different, both from the style of language and the choice of words used by each machine translation tool. Thus, directly or indirectly, whether consciously or not, each translation machine carries its characteristics. Machine translation technology cannot be separated from the active role of humans. In other words, it will always be the best choice for users to rely on expert translation rather than machine translation. But no machine translator can be as accurate as human skills in producing translation products. In particular, the field of translation is also concerned with machine translation to support the performance of translators in analyzing the diction used as an element of language. In this regard, it needs to be underlined that the existence of machine translation is an additional facility in the world of translation, not as the main means of translation because the sophistication of the machine will not be able to match the flexibility of the human brain's cognitive abilities in adjusting the translation results according to the existing context. Accurate translation is sometimes subjective, relatively often temporal. Therefore, it is permissible for translating by more than one machine translator
Cordyceps militaris: An Overview of Its Chemical Constituents in Relation to Biological Activity

Cordyceps spp. mushrooms have a long tradition of use as a natural raw material in Asian ethnomedicine because of their adaptogenic, tonic effects and their ability to reduce fatigue and stimulate the immune system in humans. This review aims to present the chemical composition and medicinal properties of Cordyceps militaris fruiting bodies and mycelium, as well as mycelium from in vitro cultures. The analytical results of the composition of C. militaris grown in culture media show the bioactive components such as cordycepin, polysaccharides, γ-aminobutyric acid (GABA), ergothioneine and others described in the review. To summarize, based on the presence of several bioactive compounds that contribute to biological activity, C. militaris mushrooms definitely deserve to be considered as functional foods and also have great potential for medicinal use. Recent scientific reports indicate the potential of cordycepin in antiviral activity, particularly against COVID-19.
Unmanned Aircraft Pilot Medical Certification Requirements

Abstract : This research addressed the medical requirements necessary for unmanned aircraft (UA) pilots for successful flight in the National Airspace System (NAS). Given that an existing medical certification was recommended, the question of which class of certification to propose was based on the perceived level of risk imposed by the potential incapacitation of the UA pilot. A second-class medical certification was judged to be the most acceptable, considering that there were several factors that mitigated the risk of pilot incapacitation relative to those of manned aircraft. First, factors related to changes in air pressure could be ignored, assuming that control stations for non-military operations would be on the ground. Second, many of the current UA systems have procedures that have been established for lost data link. Lost data link, where the pilot cannot transmit commands to the aircraft, is functionally equivalent to pilot incapacitation. Third, the level of automation of a system determines the criticality of pilot incapacitation because some highly automated systems (e.g., Global Hawk) will continue normal flight whether a pilot is or is not present. The effort consisted of the convening of a panel of subject matter experts and interactions with groups engaged in the process of establishing unmanned aircraft pilot guidelines. The results of this effort were a recommendation and justification for the use of the second-class medical certification.
On the Effect of Microwave Heating on Quality Characteristics and Functional Properties of Persimmon Juice and Its Residue

In this study, it was investigated whether integration of microwave-heating into the pretreatment step of persimmon juice processing allows the concomitant production of both functional juice and added-value solid residue from the Diospyros Kaki “Jiro” cultivar. In this direction, persimmon pulp was treated under three different microwave-heating conditions (0.7, 4.2, and 8.4 kJ/g) prior to enzymatic maceration and compared to the non-heated material. Irrespective of microwave energy employed, the proposed hybrid treatment was highly efficient in terms of juice yield (70% w/w). The mildest heating conditions resulted in juice and residue that were both of inferior quality. Intensification of the microwave energy reduced the microbial load of the juice up to 2-log without compromising the content in total soluble solids, sugars, and L-ascorbic acid. Under the most drastic conditions, the juice was enriched in gallic acid, polyphenols, and potent DPPH● scavengers, but its orange color faded and was more acidic. In parallel, the solid juice residue retained pro-vitamin A carotenoids (~278 µg retinol activity equivalents) and low-methoxy pectin (9 g/100 g DW). Overall, our findings can assist the efforts of the local juice processing industry to utilize persimmon fruits through energy-efficient technologies in a sustainable approach.
Can You Try this Model? Introducing an Instructional Leadership Model for Teacher Performance Evaluation

The school principal’s role as an instructional leader has sustained to revolutionize since the last four decades. The understanding of the complexity and ambiguity of the role has developed and the focus shifted from management and supervision to instructional leadership. This study, however, was undertaken to uncover perceptions of Omani principals have concerning their view and practice of teacher performance evaluation and challenges that affect teacher performance evaluation in Oman. This study aims to explore the school principals’ practices in carrying out the performance evaluation of teachers in selected Omani schools. Data reported in this study were gathered from three schools located in Southeast region in the Sultanate of Oman. Selection of participants is critical in qualitative research; therefore, the researcher used purposeful sampling to identify the three instructional leaders whose total experience was not less than 3 years in the same school that involved in school performance evaluation system. The sample was selected from those schools where a school level doorkeeper accepts to take place in the study. Semi-structure interview approach is used as the prime source of data, direct observations and document analysis. Interviews were recorded and transcribed literally and translated from Arabic to English. Transcripts were iteratively read and coded, then analyzed using the constant-comparative method. Codes were grouped into 8 units: (a) the conception of teacher’s performance evaluation, (b) goal setting process, (c) monitoring teacher performance, (d) feedback on teacher’s performance, (e) professional development, (f) Favored teachers (g) the principal’s motivation (h) summative evaluation. Once unitized and coded, explanation were then entered into the database for analysis. The study, however, came up with implications for practice and theory. Recommendations were taken directly from participants and the researcher added his recommendations based on the research findings and the need to improve teacher performance evaluation in Oman school.
Modeling Sound Source Localization under the Precedence Effect Using Multivariate Gaussian Mixtures

The precedence effect refers to the property of the human auditory system that enables accurate localization of sound sources where many interfering echoes of the original signal are also present. Perception of the elevation, azimuth, and distance of sound sources are affected in the presence of an echo. The multivariate Gaussian mixture model proposed in this paper combines azimuth, elevation and distance perception, and provides a general framework for modeling sound source localization under the precedence effect. The model interprets the precedence effect as a spatial property rather than a temporal one.
Optimal Powertrain Dimensioning and Potential Assessment of Hybrid Electric Vehicles

Hybrid electric vehicles (HEVs), compared to conventional vehicles, complement the traditional combustion engine with one, or several electric motors and an energy buffer, typically a battery and/or an ultracapacitor. This gives the vehicle an additional degree of freedom that allows for a more efficient operation, by e.g. recuperating braking energy, or operating the engine at higher efficiency. In order to be cost effective, the HEV may need to include a downsized engine and a carefully selected energy buffer. The optimal size of the powertrain components depends on the powertrain configuration, ability to draw electric energy from the grid, charging infrastructure, drive patterns, varying fuel, electricity and energy buffer prices and on how well adapted is the buffer energy management to driving conditions. This thesis provides two main contributions for optimal dimensioning of HEV powertrains while optimally controlling the energy use of the buffer on prescribed routes. The first contribution is described by a methodology and a tool for potential assessment of HEV powertrains. The tool minimizes the need for interaction from the user by automizing the processes of powertrain simplification and optimization. The HEV powertrain models are simplified by removing unnecessary dynamics in order to speed up computation time and allow Dynamic Programming to be used to optimize the energy management. The tool makes it possible to work with non-transparent models, e.g. models which are compiled, or hidden for intellectual property reasons. The second contribution describes modeling steps to reformulate the powertrain dimensioning and control problem as a convex optimization problem. The method considers quadratic losses for the powertrain components and the resulting problem is a semidefinite convex program. The optimization is time efficient with computation time that does not increase exponentially with the number of states. This makes it possible to include more accurate models in the optimization, e.g. powertrain components with thermal properties.
Biosorption of Chromium by Agricultural Waste, Anacardium Occidentale Testa Powder: Characterization, Kinetic, Isotherm and Thermodynamic Studies

The study on low-cost biosorbent such as Anacardium occidentale testapowder was used to remove chromium from aqueous solutions. Based on R 2 values, the Langmuir (R 2 = 0.9927) model fitted the equilibrium biosorption data best, confirming monolayer adsorption of chromium on to the biosorbent surface. The biosorption of chromium was best described by pseudo-second order (R 2 =0.9902) kinetics since at all concentrations, the R 2 values were higher than the corresponding pseudo-first order (R 2 = 0.9278) values. Based on thermodynamic parameters the biosorption of chromium by Anacardium occidentale testa powder was found to be spontaneous, endothermic and feasible under optimized conditions.
Inhibitory Control was needed in Level-1 Visual Perspective Taking: A Developing Negative Priming Study

Aim Previous studies have found that both children and adults have difficulties in dealing with judgments in which self-perspective differs from other-perspective, even in level-1 perspective-taking. However, the underlying cognitive mechanism of this is still unclear. In the present study, we designed a negative priming (NP) paradigm of the dot-perspective task to examine whether inhibitory control was required to overcome egocentric bias in level-1 visual perspective-taking in children and adults. We observed an NP effect in both children (n= 43) and adults (n= 40). However, there was no significant difference between children and adults on the magnitude of the NP effect, indicating that when children could overcome the egocentric bias, they had inhibitory control ability comparable to that of adults in level-1 other-perspective-taking. Background Visual perspective-taking is an indispensable ability in social interaction; hence, it has attracted great attention from researchers. However, the mechanism underlying this process remains unclear. The present study aimed to investigate the role of inhibitory control in level-1 visual perspective-taking from a developmental perspective in order to understand the performance differences in perspective-taking tasks between children and adults. Methods The NP paradigm was applied to the dot-perspective task. Participants’ response times (RTs) and error rates (ERs) were recorded during the experiment. A 2 (trial type: test vs control, within-subject) × 2 (age: children vs adults) mix-design ANOVA was used to analyse the RTs and ERs data separately. Results We observed an NP effect for both children (7.31, t (42) = 2.78, p < 0.01, Cohen’s d = 0.22) and adults (27.58, t (39) = 2.31, p < 0.05, Cohen’s d = 0.21). However, the difference in the magnitude of the NP effect between children and adults was not significant (t (81) = 0.54, p = 0.59). Conclusion Inhibitory control was needed to overcome egocentric bias in level-1 visual perspective-taking for both children and adults. Moreover, when children could overcome egocentric bias, they had an inhibitory control ability comparable to that of adults.
Investigation of AC Electrical Properties of MXene-PCL Nanocomposites for Application in Small and Medium Power Generation

The paper examined Ti3C2Tx MXene (T—OH, Cl or F), which is prepared by etching a layered ternary carbide Ti3AlC2 (312 MAX-phase) precursor and deposited on a polycaprolactone (PCL) electrospun membrane (MXene-PCL nanocomposite). X-ray Diffraction analysis (XRD) and Scanning Electron Microscopy (SEM) indicates that the obtained material is pure Ti3C2 MXene. SEM of the PCL-MXene composite demonstrate random Ti3C2 distribution over the nanoporous membrane. Results of capacitance, inductance, and phase shift angle studies of the MXene-PCL nanocomposite are presented. It was found that the frequency dependence of the capacitance exhibited a clear sharp minima in the frequency range of 50 Hz to over 104 Hz. The frequency dependence of the inductance shows sharp maxima, the position of which exactly coincides with the position of the minima for the capacitance, which indicates the occurrence of parallel resonances. Current conduction occurs by electron tunneling between nanoparticles. In the frequency range from about 104 Hz to about 105 Hz, there is a broad minimum on the inductance relationship. The position of this minimum coincides exactly with the position of the maximum of the phase shift angle—its amplitude is close to 90°. The real value of the inductance of the nanocomposite layer was determined to be about 1 H. It was found that the average value of the distance over which the electron tunnels was determined with some approximation to be about 5.7 nm and the expected value of the relaxation time to be τM ≈ 3 × 10−5 s.
Machine Learning (ML) Technologies for Digital Credit Scoring in Rural Finance: A Literature Review

Rural credit is one of the most critical inputs for farm production across the globe. Despite so many advances in digitalization in emerging and developing economies, still a large part of society like small farm holders, rural youth, and women farmers are untouched by the mainstream of banking transactions. Machine learning-based technology is giving a new hope to these individuals. However, it is the banking or non-banking institutions that decide how they will adopt this advanced technology, to have reduced human biases in loan decision making. Therefore, the scope of this study is to highlight the various AI-ML- based methods for credit scoring and their gaps currently in practice by banking or non-banking institutions. For this study, systematic literature review methods have been applied; existing research articles have been empirically reviewed with an attempt to identify and compare the best fit AI-ML-based model adopted by various financial institutions worldwide. The main purpose of this study is to present the various ML algorithms highlighted by earlier researchers that could be fit for a credit assessment of rural borrowers, particularly those who have no or inadequate loan history. However, it would be interesting to recognize further how the financial institutions could be able to blend the traditional and digital methods successfully without any ethical challenges.
Spatial Structure Characteristics of Tourist Attraction Cooperation Networks in the Yangtze River Delta Based on Tourism Flow

This study aimed to examine the spatial structure of the tourist attraction cooperation network in the Yangtze River Delta, from the perspective of tourist flow. This study conducted spatial and social network analyses of 470 popular tourist attractions in the Yangtze River Delta region of China, accounting for the occurrence and co-occurrence of tourist attraction information in tourist travel notes. The analyzed tourist attractions show an obvious spatial agglomeration effect, including four high-density agglomeration areas and two medium-density agglomeration areas. Degree centrality, closeness centrality, and betweenness centrality were used to examine the tourism function, distribution function, and connection function of nodes in the network; nodes were divided into various types of roles according to their function. There are eight condensed subgroups, but their scales are unbalanced. In these condensed subgroups, several tourist attractions with an intermediate function can be selected as transit and stopover points on tourist routes. This study can contribute to the understanding of tourists’ spatial behavior, clarify the role and status of nodes in the cooperation network of tourist attractions based on tourism flow, and help them to formulate measures for the joint marketing of tourist attractions, and promote the development of tourism in the Yangtze River Delta region.
Electro Mechanical Actuator Test Stand for In-Flight Experiments

The Prognostic Center of Excellence at NASA Ames is currently researching actuator prognostics, specifically in the application of electro mechanical actuators (EMA’s). Cal Poly ME students Michael Koopmans and Catlin Mattheis and EE student Austin Lawrence have chosen to undertake the task of building a test stand that will be flown in flight while testing EMA’s specific faults. A stand was designed to fit inside a standard 19” rack, take power from the aircraft 3 EMA’s, a computer, data acquisition, and electric magnets switches are powered. A MIL STD 1553 interface is present to allow fault injection. Vibration and temperature data can be recorded during experiments. However, due to time constraints, not all tests were completed and the control system needs optimization. The stand is 90% complete and with a little more work the test stand should generate interesting and valuable data to compliment the Health Systems Management algorithms relating actuator faults and numerical relationships.
