Redox Stable Electrode Material of Symmetrical Solid Oxide Fuel Cells

Solid oxide fuel cells (SOFCs) technologies are considered the most efficient and environmentally-friendly option for both stationary and distributed power generation due to their advantages of low pollution, low noise and strong building blocks. Despite the potential, widespread adoption of SOFC technology has not yet been achieved. The main reason is that the high cost of manufacturing and maintenance and the insufficient operating life make SOFC technology less competitive economically. More and more people begin to pay attention to symmetrical solid oxide fuel cells (SSOFCs) because SSOFCs have many potential advantages, such as improving the thermal mechanical compatibility between electrolyte and electrode, reducing manufacturing costs, and improving the ability to resist coking and sulfur poisoning. This article reviews the development of SSOFCs redox stable electrodes in recent years, summarizes the current research hotspots, and looks forward to the future development of redox stable electrode materials.
Combined Effect of Cinnamon Bark Oil and Packaging Methods on Quality of Fresh Lamb Meat Patties during Storage at 4 °C

The present study aimed to investigate the effects of adding cinnamon bark oil (CBO) on the quality of ground lamb meat, considering different packaging conditions, including modified atmospheric packaging (MAP) using Hengxian HX-300H and overwrapped packaging. The CBO was incorporated into lamb meat samples at three different levels: 0% (control), 0.025% and 0.05% (v/w). The samples were then subjected to three packaging methods: MAP1 (80% O2 + 20% CO2), MAP2 (40% O2 + 30% CO2 + 30% N2) and overwrapped packaging and stored at 4 °C for 0, 4, 8, 12 and 16 days. The findings of the present study revealed that the addition of 0.025% and 0.05% CBO under MAP1 condition significantly improved the color of the meat samples after 12 days of storage at 4 °C (p < 0.05). The overwrapped samples exhibited higher levels of thiobarbituric acid reactive substances (TBARS) compared to all other treatments, starting from day 4 of storage (p < 0.05). Furthermore, microbial counts were notably higher in the overwrapped samples than in all other samples after day 8 of storage (p < 0.05). In conclusion, the combination of 0.05% CBO with MAP proved to be an effective strategy for enhancing the color stability and oxidative stability of ground lamb meat. These results suggest that CBO can be utilized as a beneficial protective agent in meat packaging processes.
Large thermopower from dressed quasiparticles in the layered cobaltates and rhodates

Author(s): Chen, SD; He, Y; Zong, A; Zhang, Y; Hashimoto, M; Zhang, BB; Yao, SH; Chen, YB; Zhou, J; Chen, YF; Mo, SK; Hussain, Z; Lu, D; Shen, ZX | Abstract: © 2017 American Physical Society. The origin of the large thermopower in NaxCoO2 is complicated by correlation phenomena. To disentangle the effects from multiple interactions, we use angle-resolved photoemission to study KxRhO2, an isostructural analogy of NaxCoO2 with large thermopower and weak electron correlation. Using the experimentally measured electronic structure, we demonstrate that the thermopower in KxRhO2 can be quantitatively explained within the quasiparticle framework after including an electron-phonon mass enhancement effect. Extending the analysis to the cobaltate, we find the doubling in thermopower is well accounted for by additional band renormalization from electron correlation. As such, the large thermopower emerges from the itinerant quasiparticles dressed by hierarchical electron-phonon and electron-electron interactions.
Effect of Dietary Orange Peel Meal and Multi-Enzymes on Productive, Physiological and Nutritional Responses of Broiler Chickens

Simple Summary Agricultural byproducts can play a significant role in poultry nutrition as an alternative to traditional ingredient resources. Orange peel meal has the potential to be a source of essential nutrients and reduce oxidative stress in chickens. The addition of dietary orange peel meal to broiler chicken diets at the four graded concentrations of 0, 80, 160, and 240 g kg‒1 with or without multi-enzymes was evaluated in this study. The study concluded that orange peel meal improved body weight gain, the feed conversion ratio (FCR) during the grower phase, antioxidant capacity, and decreased abdominal fat; multi-enzyme addition improved body weight gain, FCR during the grower phase, crude fiber digestibility, T3 levels, and decreased the fat percentage; and an interaction effect was observed only for SOD levels, where SOD levels decreased due to the addition of enzymes. Abstract The objective of the study was to evaluate the impact of various concentrations of orange (Citrus sinensis) peel meal (OPM), with or without the supplementation of multi-enzymes, on the growth performance, nutrient digestibility, antioxidant properties, and blood metabolic profile of broiler chickens. The experiment was conducted on 240 one-day-old Arbor Acres broiler chicks, assigned to eight dietary treatments with 30 broilers per treatment group. Four dietary orange peel meal (OPM) concentrations were supplemented, namely, the control (without OPM), and with 80, 160, and 240 g/kg of the diet. To each of these diets was added two concentrations of multi-enzyme inclusion (0 or 0.6 g as a combination of 0.5 g of Nutrikem and 0.1 g Optiphos per kg diet) in a completely randomized design in a 4 × 2 factorial arrangement. The experiment lasted until 42 days of age. Body weight gain (BWG) was influenced during the grower period (22–42 days) and the overall period (0–42 days), and the feed conversion ratio (FCR) was significantly improved by supplementations of OPM compared with the control for 22–42 days and overall (0–42 days) periods. Moreover, BWG, FCR during the grower and overall periods, and crude fiber digestibility were improved (p < 0.01) by multi-enzyme supplementation compared to the non-supplemented groups. Broilers with diets supplemented with OPM had considerably lower abdominal fat (p < 0.01) than the control. In addition, when compared to the non-supplemented enzyme group, serum T3 and T3/T4 ratios were significantly improved in response to enzyme addition. When compared to the control group, superoxide dismutase (SOD) was significantly higher in the OPM groups, showing the largest improvement in antioxidant response. Interaction effects were observed only for serum SOD levels. Based on our findings, it is recommended that OPM be used as a feed supplement for raising broilers, and adding 0.6 m g/kg of multi-enzymes could provide additional benefits to the performance of broilers.
Design of a Four-Axis Robot Arm System Based on Machine Vision

With the concept of industrial automation gradually being put forward, the four-axis robotic arm is gradually being applied in industrial production environments due to its advantages such as a stable structure, easy maintenance, and expandability. However, it is difficult to diversify and improve the traditional four-axis robotic arm system due to the high software and hardware coupling and the single system design, which results in high production costs. At the same time, its low intelligence and high-power consumption limit its wide application. The paper proposes an embedded design of a four-axis manipulator system based on vision guidance. Based on the robot kinematics theory and geometric principles, the dynamics simulation of the manipulator model is carried out. Through the forward and reverse analysis of the manipulator model and the trajectory planning of the manipulator, the YOLOV7 target detection algorithm is introduced and deployed on the embedded device, which greatly reduces the manufacturing cost of the manipulator while meeting the control and power consumption requirements. It has been verified by experiments that the robot arm in this paper can achieve an end accuracy of 0.05 mm under the condition of a load of 1 kg using the ISO 9283 international standard, and the recognition algorithm adopted can achieve a recognition accuracy of 95.2% at a frame rate of 29. The overall power consumption is also lower than that of traditional robotic arms.
Origin of Soft-Switching Output Capacitance Loss in Cascode GaN HEMTs at High Frequencies

Output capacitance (<italic>C</italic><sub>OSS</sub>) loss (<italic>E</italic><sub>DISS</sub>) is produced when the <italic>C</italic><sub>OSS</sub> of a power device is charged and discharged, which ideally should be a lossless process. This loss was recently revealed to be a crucial concern for GaN high electron mobility transistors (HEMTs) in high-frequency soft-switching applications. Among various GaN devices, the composite-type, cascode GaN HEMT was reported to show the largest <italic>E</italic><sub>DISS</sub> with a voltage dependence distinct from discrete GaN HEMTs. However, the physical origins of the <italic>E</italic><sub>DISS</sub> in cascode GaN HEMTs remain unclear. This article fills this gap by identifying three loss components and, for the first time, experimentally quantifying them in the multi-MHz resonant switching. These loss components include: a) the avalanche loss of Si <sc>mosfet</sc>; b) the intrinsic <italic>E</italic><sub>DISS</sub> of GaN HEMT; and c) the Si avalanche-induced GaN turn-<sc>on</sc> loss. The last component was found to dominate <italic>E</italic><sub>DISS</sub> at high voltage. By eliminating the Si avalanche and the associated loss components (a) and (c), the <italic>E</italic><sub>DISS</sub> of cascode GaN HEMTs can be reduced by up to 75% at the price of an increase in output charge and switching transition time. These results provide new physical insights and practical guidelines to trim the soft-switching loss of cascode GaN HEMTs in high-frequency applications.
The Human Capital of Technicians in State University of Malang

Agencies or companies' ability to create and develop strategies to advance depend on human capital. It receives public attention as tangible state assets, policies, and organizations and are described as the core vital forces in the professional world. It is essential because it provides companies with some new skills, opportunities, and even development. This study aims to describe the human capital (knowledge, competence, skill, and innovation) of the technicians in the State University of Malang using a survey research design. The population is the technicians in the State University of Malang. The result indicates that the human capital in the State University of Malang can be categorized as follows: 3.1 percent of the technicians are very positive (one technician), 31.3 percent are (ten technicians), 34.4 percent are average (11 technicians), 28.1 percent are negative (nine technicians), and 3.1 percent are very negative (one technician). It can be concluded that the human capital of the State University of Malang is average, which implies that not all the employees can perform well at work and meet the indicators; hence, the need for improvement.
MATHEMATICAL MODELING OF THE INTERPLAY BETWEEN STRESS AND ANISOTROPIC GROWTH OF AVASCULAR TUMORS

In this work, we propose a new mathematical framework for the study of the mutual interplay between anisotropic growth and stresses of an avascular tumor surrounded by an external medium. The mechanical response of the tumor is dictated by anisotropic growth, and reduces to that of an elastic, isotropic, and incompressible material when the latter is not taking place. Both proliferation and death of tumor cells are in turn assumed to depend on the stresses. We perform a parametric analysis in terms of key parameters representing growth anisotropy and the influence of stresses on tumor growth in order to determine how these effects affect tumor progression. We observe that tumor progression is enhanced when anisotropic growth is considered, and that mechanical stresses play a major role in limiting tumor growth.
Antibody responses to an inactivated SARS-CoV-2 vaccine in individuals aged from 50 to 102 years

Objectives To assess antibody responses to an inactivated SARS-CoV-2 vaccine in individuals aged 50 and older. Methods We conducted a post-market cross-sectional seroepidemiology study. We recruited 4,632 vaccinated individuals aged 50 and older, measured their total serum SARS-CoV-2-specific antibody (TA), and collected correlates. The primary outcome was the geometric mean titer (GMT) of TA, and the secondary outcome was the decline of TA with age. Univariate, bivariate, and multivariate analyses were used to examine the associations of the TA GMT with age, and trend analyses were used to test whether their associations were significant. Results All participants had a detectable TA, which was generally at a low level across all age groups. The TA GMT (95% CI) in AU/mL was 3.05 (2.93, 3.18); the corresponding arithmetic mean (95% CI) was 17.77 (16.13, 19.42) in all participants and 4.33 (3.88, 4.84), 3.86 (3.49, 4.28), 3.24 (2.92, 3.59), 2.77 (2.60, 2.96), and 2.65 (2.48, 2.83) in the age groups of 50-54, 55-59, 60-64, 65-74, and 75 years or older, respectively. The TA GMT decreased with age with a P trend < 0.001. The TA GMT was significantly lower in those with hypertension or diabetes compared to those with neither. Conclusion The inactivated SARS-CoV-2 vaccine is effective in individuals aged 50 and older. This is the first study that has found an inverse dose-response relationship between ages and the low-level TAs. Older people, especially those with chronic diseases, should get the SARS-CoV-2 vaccine, and their vaccination frequency, dose, and method may need to be different from those of younger people.
Anomalous Grain Growth in a Polycrystalline Monolayer of Colloidal Hard Spheres

Understanding grain growth is key for controlling the microstructure and the mechanical properties of most polycrystalline materials, including metals, alloys, and ceramics. However, the precise mechanisms and kinetics of grain growth remain poorly understood both at the theoretical level and experimentally as direct observation is cumbersome in atomic systems. Here, we study the grain growth process in a polycrystalline monolayer of colloidal hard spheres. We find that the bond-orientational correlation function satisfies the dynamic scaling hypothesis and has the general scaling form predicted for systems containing random domain walls. However, the associated correlation length grows slower than ∼t1=2, which corresponds to normal curvature-driven grain growth. To understand the origin of this anomalous grain growth, we directly monitor the evolution of the grain boundary network by measuring the so-called grain boundary character distribution. We show that there is a strong annihilation of large-angle grain boundaries while small-angle grain boundaries become relatively more present. Using scaling arguments, we derive the time dependence of the correlation length and show its good agreement with the data. We conclude that the origin of anomalous grain growth is the curvature-driven coarsening of the large-angle grain boundaries at a rate that depends on their relative length in the total grain boundary network.
Intestinal Immune Imbalance is an Alarm in the Development of IBD

Immune regulation plays a crucial role in human health and disease. Inflammatory bowel disease (IBD) is a chronic relapse bowel disease with an increasing incidence worldwide. Clinical treatments for IBD are limited and inefficient. However, the pathogenesis of immune-mediated IBD remains unclear. This review describes the activation of innate and adaptive immune functions by intestinal immune cells to regulate intestinal immune balance and maintain intestinal mucosal integrity. Changes in susceptible genes, autophagy, energy metabolism, and other factors interact in a complex manner with the immune system, eventually leading to intestinal immune imbalance and the onset of IBD. These events indicate that intestinal immune imbalance is an alarm for IBD development, further opening new possibilities for the unprecedented development of immunotherapy for IBD.
Phylogeny of Leontopodium (Asteraceae) in China—with a reference to plastid genome and nuclear ribosomal DNA

The infrageneric taxonomy system, species delimitation, and interspecies systematic relationships of Leontopodium remain controversial and complex. However, only a few studies have focused on the molecular phylogeny of this genus. In this study, the characteristics of 43 chloroplast genomes of Leontopodium and its closely related genera were analyzed. Phylogenetic relationships were inferred based on chloroplast genomes and nuclear ribosomal DNA (nrDNA). Finally, together with the morphological characteristics, the relationships within Leontopodium were identified and discussed. The results showed that the chloroplast genomes of Filago, Gamochaeta, and Leontopodium were well-conserved in terms of gene number, gene order, and GC content. The most remarkable differences among the three genera were the length of the complete chloroplast genome, large single-copy region, small single-copy region, and inverted repeat region. In addition, the chloroplast genome structure of Leontopodium exhibited high consistency and was obviously different from that of Filago and Gamochaeta in some regions, such as matk, trnK (UUU)-rps16, petN-psbM, and trnE (UUC)-rpoB. All the phylogenetic trees indicated that Leontopodium was monophyletic. Except for the subgeneric level, our molecular phylogenetic results were inconsistent with the previous taxonomic system, which was based on morphological characteristics. Nevertheless, we found that the characteristics of the leaf base, stem types, and carpopodium base were phylogenetically correlated and may have potential value in the taxonomic study of Leontopodium. In the phylogenetic trees inferred using complete chloroplast genomes, the subgen. Leontopodium was divided into two clades (Clades 1 and 2), with most species in Clade 1 having herbaceous stems, amplexicaul, or sheathed leaves, and constricted carpopodium; most species in Clade 2 had woody stems, not amplexicaul and sheathed leaves, and not constricted carpopodium.
Are numbers' mental representations spatially encoded? Around the representational Effect in Mathematics

Current cognitive accounts on numbers’ mental representations do not agree on their spatial-sensitive nature. On one hand, a Internalist neuro-based approach, supported by trans-notational conservation of cognitive effects related with mathematical tasks has postulate a quantity-based analogical format while the concurrent Externalist problem solving based approach has suggested that some of the primitive components of numbers’ mental representation might depend directly to the spatial features of numbers’ written representations. The purpose of this article is an epistemological and descriptive one. Advocating for the second tradition, we shall present both accounts, focusing on exotic cases of non-positional number systems, to disentangle their shallow contradiction.
Analyzing the Relationships Between Frequency of Leisure Activity Participation and Social Capital

Transportation research has focused on gaining a better understanding of how the need to travel is influenced by one’s social capital and relates to participation in various leisure activities. This study postulated that increased participation frequency of social-oriented leisure activities is an expressive outcome and thus mostly affected by expressive resources of social capital. To explore the impacts of social capital on leisure activity behavior—particularly the participation frequency—a refined survey was designed to obtain an extensive collection of leisure activities, social capital measures, as well as mobility and sociodemographic characteristics. The survey included questions to ascertain individuals’ instrumental and expressive social capital through position, resource, and generalized name generators. The 20 activities that were most reported by the survey respondents were examined using a zero-inflated ordered probit model with correlated error terms. Respondents with greater expressive resources participated in social leisure activities more frequently than those with fewer expressive resources. However, this relationship did not hold for the activities of drinking and socializing, attending church, or dining out. In contrast, instrumental social capital had mixed effects (i.e., positive, negative, or insignificant) in relation to the participation frequency of social activities.
Obesity-Related Atrial Fibrillation: Cardiac Manifestation of a Systemic Disease

Atrial fibrillation (AF) is the most common arrhythmia worldwide and is associated with increased morbidity and mortality. The mechanisms underlying AF are complex and multifactorial. Although it is well known that obesity is a strong risk factor for AF, the mechanisms underlying obesity-related AF are not completely understood. Current evidence proposes that in addition to overall hemodynamic changes due to increased body weight, excess adiposity raises systemic inflammation and oxidative stress, which lead to adverse atrial remodeling. This remodeling includes atrial fibrosis, atrial dilation, decreased electrical conduction between atrial myocytes, and altered ionic currents, making atrial tissue more vulnerable to both the initiation and maintenance of AF. However, much remains to be learned about the mechanistic links between obesity and AF. This knowledge will power the development of novel diagnostic tools and treatment options that will help combat the rise of the global AF burden among the obesity epidemic.
Constraints encountered by farm women in vegetable farming in Mandi district of Himachal Pradesh

The study identified constraints encountered by farm women in vegetable farming in Mandi district of Himachal Pradesh. The data were personally collected from 100 farm women of two vegetable growing blocks of the district by using multi-stage sampling technique. Overall, majority (69%) of respondents encountered medium to high extent of constraints. The study revealed that lack of knowledge about enterprise, marketing linkages, schemes of developmental departments, training and financial institutions, lack of financial institutions and difficulty in getting loan, high cost and non-availability of quality inputs in time, lack of entrepreneurship development oriented trainings and requisite support were the major constraints. Lack of marketing centers, low price of produce, lack of storage and irrigation facilities, non-availability of labour, and stray animals were the major general constraints. Effective policy at government level for stray animals and monkeys, timely availability of quality inputs at subsidized rates, promotion of processing units and financial institutes at village level and trainings on entrepreneurship development for socio economic upliftment of farm women are the prime concerns to be looked upon.
Traveling wave solutions for a delayed diffusive SIR epidemic model with nonlinear incidence rate and external supplies

In this paper, we study the traveling wave solutions of a delayed diffusive SIR epidemic model with nonlinear incidence rate and constant external supplies. We find that the existence of traveling wave solutions is determined by the basic reproduction number of the corresponding spatial‐homogenous delay differential system and the minimal wave speed. The existence is proved by applying Schauder's fixed point theorem and Lyapunov functional method. The non‐existence of traveling waves is obtained by two‐sided Laplace transform.
