Efficiency of the Wireless Power Transfer System with Planar Coils in the Periodic and Aperiodic Systems

This article presents the results of the proposed numerical and analytical analysis of the Wireless Power Transfer System (WPT). The system consists of a transmitting surface and a receiving surface, where each of them is composed of planar spiral coils. Two WPT systems were analysed (periodic and aperiodic) considering two types of coils (circular and square). In the aperiodic system, the adjacent coils were wound in the opposite direction. The influence of the type of coils, the winding direction, the number of turns, and the distance between the coils on the efficiency of the WPT system was compared. In periodic models, higher efficiency was obtained with circular rather than square coils. The results obtained with both proposed methods were consistent, which confirmed the correctness of the adopted assumptions. In aperiodic models, for a smaller radius of the coil, the efficiency of the system was higher in the square coil models than in the circular coil models. On the other hand, with a larger radius of the coil, the efficiency of the system was comparable regardless of the coil type. When comparing both systems (periodic and aperiodic), for both circular and square coils, aperiodic models show higher efficiency values (the difference is even 57%). The proposed system can be used for simultaneous charging of many sensors (located in, e.g., walls, floors).
Exploring the Analogy in the Emergent Properties of Locomotion Gaits of Snakebot Adapted to Challenging Terrain and Partial Damage

The objective of this work is to investigate the emergent properties of the gaits of the simulated snake-like robot, Snakebot. The gaits are automatically designed through Genetic Programming (GP) to be robust, general, adaptive, and the fastest possible sidewinding, locomotion. Considering the notion of emergent intelligence as the ability of Snakebot to achieve its goals (of moving fast) without the need to be explicitly taught how to do so, we present empirical results demonstrating the emergence of sidewinding locomotion from relatively simple motion patterns of morphological segments of Snakebot. We discuss the emergent properties of the evolved robust high velocity sidewinding locomotion gaits of Snakebot when situated in challenging environments. Then we elaborate on the ability of Snakebot to adapt to partial damage by gradually improving its velocity characteristics, and the emergent properties of obtained adaptive gaits. Verifying the practical implications of the analogy between the emergent properties of the robust and the adaptive sidewinding gaits, this work could be viewed as a step towards building real Snakebots, which are able to perform robustly in challenging environments.
Metaproteomics Approach and Pathway Modulation in Obesity and Diabetes: A Narrative Review

Low-grade inflammatory diseases revealed metabolic perturbations that have been linked to various phenotypes, including gut microbiota dysbiosis. In the last decade, metaproteomics has been used to investigate protein composition profiles at specific steps and in specific healthy/pathologic conditions. We applied a rigorous protocol that relied on PRISMA guidelines and filtering criteria to obtain an exhaustive study selection that finally resulted in a group of 10 studies, based on metaproteomics and that aim at investigating obesity and diabetes. This batch of studies was used to discuss specific microbial and human metaproteome alterations and metabolic patterns in subjects affected by diabetes (T1D and T2D) and obesity. We provided the main up- and down-regulated protein patterns in the inspected pathologies. Despite the available results, the evident paucity of metaproteomic data is to be considered as a limiting factor in drawing objective considerations. To date, ad hoc prepared metaproteomic databases collecting pathologic data and related metadata, together with standardized analysis protocols, are required to increase our knowledge on these widespread pathologies.
Effect of BMI on Foot Dimensions in Different Weight Bearing Conditions of Obokwe Indigenes in Imo State

The understanding of the effect of BMI on foot dimensions under different weight bearing conditions can help in the design and production of a comfortable and efficient foot support. This study is aimed at using Body Mass Index (BMI) to correlate the foot dimensions of males and females under different weight bearing conditions. The foot dimensions of 320 subjects (160 males and 160 females) between the age range of 19 and above with normal foot were measured under three weight bearing conditions: non-weight bearing, semi-weight bearing, and full-weight bearing. Height, weight and BMI of the individuals were recorded. The data collected was analysed using SPSS software version (20). Paired sample t-test and Pearson correlation coefficient test was done for calculating the statistical significance. The change in foot breadth of semi-weight bearing condition (FBSN) produced a significant correlation with BMI(p<0.05) but that with Foot length (FLSN) and Arch height (AHSN) was not statistically significant for the males. Also, the change in Foot length of full weight bearing condition (FLFN), Foot breadth (FBFN) and Arch height (AHFN) was not statistically significant for the males. There was significant correlation between BMI and the change in foot dimensions such as FLFN, AHSN, AHFN (p<0.05) but that with FLSN, FBSN and FBFN was not statistically significant for the females. Not all foot dimensions can be significantly influenced by BMI. This study is useful in considering the effect of BMI in the change of foot shape in weight-bearing during the selection of shoe size and shoe or insole design and construction and to the orthotics during the design of fitting devices for foot support. Also, it can be useful in forensic science.

The Sesame (Sesamum indicum L.) Value Chain and Microbiological Quality of Crude Sesame Oil, a Case Study in Western Tigray, Ethiopia

Crude sesame oil (CSO) is the widely used unrefined edible oil. Storage instability, off-flavour, and discoloration are, however, challenges in the industry. The purpose of this study was to map the sesame value chain, assess the suitability of CSO extraction plant, and analyze the microbial quality of CSO and premises environment. A structured Questionnaire and checklist were used to assess the sesame value chain and evaluate the suitability of the CSO extraction plant. Microbiological quality assessment was conducted using standard analytical methods. Stakeholders in the sesame value chain were inclusive of farmers, market mediators, traders, regulatory, extension workers and researchers. Though, illiteracy, inadequate technology, and infrastructure were the drawbacks. The CSO extraction plant was suitable apart from inadequate ingredients and CSO handling and unhygienic practices. Total aerobic bacteria (4.34 5.06 log10 CFU/m on swap surfaces, 2.44 log10 CFU/g in CSO), total Coliforms (5.81 log10 CFU/g of animal manure and 1.36 log10 CFU of indoor air after extraction), yeasts and moulds (2.31 log10 CFU/g of sesame seed and CSO and 4.47 log10 CFU/m of swap sample), Aspergillus species (1.17 1.33 log10 CFU/g of sesame seed/CSO, 3.37 3.50 log10 CFU/m of swap samples), and Staphylococcus aureus (2.09 log10 CFU/g of CSO, 2.56 3.22 log10 CFU/m of surface swaps, 3.26 3.77 log10 CFU/protective clothing, 0.74 1.82 log10 CFU of the indoor and outdoor air) were detected. Escherichia coli, Salmonella and Shigella were not detected. In conclusion, potential microbial pathogens were detected to impose food safety problems and economic loss. To improve the sesame value chain and CSO quality workers training on good handling and hygienic practices and thoughtful regulatory implementation are significant.

Modeling of Single Electron Charging in Nanocrystal Memories

A three-dimensional model is proposed to describe single electron charging into the nanocrystals that compose the floating gate of a metal-oxide-semiconductor transistor. It is built on the physical and geometrical parameters of the device. If the nanocrystals have a cylindrical symmetry, the 3D approach can be analytically reduced to a 2D model. Different effects that play an important part on single electron charging, such as the electrostatic coupling between two nanocrystals and the doping density of the channel, are analysed. Moreover the necessity of including the excited states of the nanocrystals and the subbands of the channel is shown. Finally the tunneling times to charge the nanocrystals in the floating gate from the channel are simulated and discussed.

Performance Evaluation of a Voice-Based Depression Assessment System Considering the Number and Type of Input Utterances

It is empirically known that mood changes affect facial expressions and voices. In this study, the authors have focused on the voice to develop a method for estimating depression in individuals from their voices. A short input voice is ideal for applying the proposed method to a wide range of applications. Therefore, we evaluated this method using multiple input utterances while assuming a unit utterance input. The experimental results revealed that depressive states could be estimated with sufficient accuracy using the smallest number of utterances when positive utterances were included in three to four input utterances.
Preoperative Embolization With Fused CT Angiography and Tractography Facilitates Safe Resection of a Spetzler-Martin Grade IV Arteriovenous Malformation

Brain arteriovenous malformations (BAVMs) are high-flow vascular lesions that have a propensity to rupture resulting in high rates of morbidity and mortality. Microsurgical resection of BAVMs is the standard of care for high-risk, resectable lesions. Multiple imaging modalities aid in the surgical planning and resection of high-grade BAVMs, but all have hidden variables that would prove useful if available. We present a 20-year-old male with a ruptured BAVM with concern for the involvement of the corticospinal tract (CST) and basal ganglia. We describe the melding of computed tomography angiography (CTA) and diffusion tensor imaging (DTI) in addition to preoperative embolization to aid in the planning and resection of a lesion close to eloquent structures. Post-operative CTA and DTI showed a total resection of the lesion with retained CST white matter tracts, and the patient retained the functional ability of the contralateral limbs. The combination of CTA, brain DTI, and preoperative embolization provides a framework to improve the safety of resection of BAVMs that occur near eloquent brain networks.
The Role of the Universally Conserved ATPase YchF/Ola1 in Translation Regulation during Cellular Stress

The ability to respond to metabolic or environmental changes is an essential feature in all cells and involves both transcriptional and translational regulators that adjust the metabolic activity to fluctuating conditions. While transcriptional regulation has been studied in detail, the important role of the ribosome as an additional player in regulating gene expression is only beginning to emerge. Ribosome-interacting proteins are central to this translational regulation and include universally conserved ribosome interacting proteins, such as the ATPase YchF (Ola1 in eukaryotes). In both eukaryotes and bacteria, the cellular concentrations of YchF/Ola1 determine the ability to cope with different stress conditions and are linked to several pathologies in humans. The available data indicate that YchF/Ola1 regulates the stress response via controlling non-canonical translation initiation and via protein degradation. Although the molecular mechanisms appear to be different between bacteria and eukaryotes, increased non-canonical translation initiation is a common consequence of YchF/Ola1 regulated translational control in E. coli and H. sapiens. In this review, we summarize recent insights into the role of the universally conserved ATPase YchF/Ola1 in adapting translation to unfavourable conditions.
High-Glucose and Free Fatty Acid-Induced Adipocytes Generate Increasing of HMGB1 and Reduced GLUT4 Expression

Background High-mobility group box 1 protein (HMGB1) is released from necrotic adipocytes into the extracellular milieu as an inflammatory alarmin in obesity. Although the impact of excess nutrient on adipocytes is well known, it is not clear how specific its component drive cell-size and damaged of adipocytes, and how this relates to the risk of insulin resistance. Objectives The aim of this study was to determine HMGB1 level in adipocytes cultures after high glucose and/or FFA exposures and to assess GLUT4 expression. We determined cellular features of adipocytes that correlates to HMGB1 released and insulin resistance. Methods Differentiated adipocytes were exposed to high glucose and/or FFAs for 7 days. ELISA was performed on supernatant to assess the HMGB1 level. Total GLUT4 expression were quantified by immunofluorescense. Results High glucose and FFA-exposed cells have significant increase of HMGB1 level with decreased of cell size and necrotic adipocytes features. The total GLUT4 were reduced in HG-cells (p <0,045), but not in FFA cells. Hypertrophic adipocytes (p <0.05) and slight decrease of GLUT4 expression were showed on HG+FFA exposures with no increase of HMGB1 level. There was a significant correlation between cell size and HMGB1 level (R -0,637, p < 0.026) Conclusion The expression level studies between high glucose, FFA, and a combination of both on adipocytes results strongly suggest that high glucose is more damaging to adipocyte compared to FFA. Nevertheless, the combination of the two causes adipocyte dysfunction with general features of adipose tissue in obesity, suggested it can be used as a hypertrophic adipocytes model to study obesity in vitro.
Chemically Dual-Modified Biochar for the Effective Removal of Cr(VI) in Solution

Here, a dual-modification strategy using KMnO4 (potassium permanganate) and AlCl3·6H2O (aluminum chloride, hexahydrate) as co-modifiers to improve the Cr(VI) removal capacity of K2CO3 activated biochar is introduced. As a result, the dual-modified biochar with KMnO4 and AlCl3·6H2O has the calculated adsorption energy of −0.52 eV and −1.64 eV for HCrO4−, and −0.21 eV and −2.01 eV for Cr2O72−. The Al2O3 (aluminum oxide) and MnO (manganese oxide) embedded on the surface of dual-modified biochar bring more Cr(VI) absorption sites comparing to single-modified biochar, resulting in a maximum Cr(VI) saturated adsorption capacity of 152.86 mg g−1. The excellent removal performance is due to the synthetic effect of electrostatic attraction, reduction reaction, complexation reaction, and physical adsorption. The experimental results also indicated that the spontaneous adsorption process agreed well with the pseudo-second order and Langmuir models. This dual-modification strategy is not limited to the treatment of Cr(VI) with biochar, and may also be incorporated with the treatment of other heavy metals in aqueous environment.
Geospatial Information Relevant to the Flood Protection Available on The Mainstream Web

Abstract Flood protection is one of several disciplines where geospatial data is very important and is a crucial component. Its management, processing and sharing form the foundation for their efficient use; therefore, special attention is required in the development of effective, precise, standardized, and interoperable models for the discovery and publishing of data on the Web. This paper describes the design of a methodology to discover Open Geospatial Consortium (OGC) services on the Web and collect descriptive information, i.e., metadata in a geocatalogue. A pilot implementation of the proposed methodology - Geocatalogue of geospatial information provided by OGC services discovered on Google (hereinafter “Geocatalogue”) - was used to search for available resources relevant to the area of flood protection. The result is an analysis of the availability of resources discovered through their metadata collected from the OGC services (WMS, WFS, etc.) and the resources they provide (WMS layers, WFS objects, etc.) within the domain of flood protection.

Taken into account the process limitation, we will also discuss the critical steps and their impact on the electrical characteristics. A design methodology based on Baliga's criterion is proposed to obtain the optimal structure. A 50 nm thick thermal oxide grown above vertical channel and the use of a buried p+ layer as second gate electrode are brand new in front of what is found in literature.
CPG-based Control of Serpentine Locomotion of a Snake-like Robot*

In this paper, a biomimetic approach is proposed to solve the difficulty in control of a snake-like robot with a large number of degrees of freedom. This method is based on the central pattern generator (CPG), which is a rhythmical motion generator existing in most animals. Compared with the previous research, a new network with feedback connection is presented, which can generate uniform outputs without any adjustment. Furthermore, the relation characteristics between the CPG parameters and the outputs are investigated. Both simulation and experiment of the snake-like robot have been taken for the analysis of the locomotion control. Desired locomotion patterns can be achieved by adjusting the CPG parameters correspondingly from the results.
