Smart Wi-Fi Antenna With Reconfigurable Omnidirectional and Unidirectional Patterns

A compact pattern-reconfigurable antenna based on the electromagnetic complementary Huygens principle is developed in this letter. The vertically polarized antenna comprises a slot-loading shorted patch printed on the lower substrate and a mushroom structure printed on the upper substrate. The shorted patch is considered to have the same operating characteristics as the half-mode substrate integrated waveguide, which is equivalent to a slot magnetic dipole. The zeroth-order resonance is excited for the mushroom structure, which is equivalent to an electric dipole. The slot-loaded ground is used to expand the bandwidth. The omnidirectional and end fire directional radiation patterns are obtained by controlling the states of the mushroom with two PIN diodes. The antenna with a compact size of 0. 19λ0 × 0. 45λ0 × 0. 033λ0 (λ0 represents the free space wavelength at 2.45 GHz) is developed. The measured −10 dB impedance bandwidth is covered the 2.4 GHz WLAN band (2.40–2.48 GHz). The proposed antenna shows great application potential for intelligent Wi-Fi communication systems.
Espektro zabaleko antigorputzen rola GIBaren aurkako terapian eta prebentzioan

Terapia antirretrobiral konbinatuaren erabilera iraultza bat izan zen GIBaren infekzioaren tratamenduan eta prebentzioan. Hala ere, terapia hau ez da gai birusa organismotik erabat ezabatzeko, eta GIB infekzio kasu berrien munduko tasak mantso jaisten jarraitu du. Beraz, GIBaren prebentzio eta tratamendurako ikuspegi berriak aztertzeko beharra dago. Antigorputzak GIBaren aurkako aukera terapeutiko gisa proposatuak izan dira, epitopo biralak blokeatzeaz gain ostalariaren immunitate sistemarekin elkar ekiteko gaitasuna dutelako. Azken urteotan, GIBaren fusio proteinaren eskualde desberdinak ezagutzen dituzten espektro zabaleko zenbait antigorputz neutralizatzaile (bnAb) saio klinikoetan ebaluatuak izan dira. Lan honetan, GIBaren testuinguruan bnAb-ek eskaintzen dituzten aukerak eta beren garapen klinikoan ager daitezkeen oztopoak aztertuko dira.
Phosphate solubilization potential and molecular identification of bacterial isolates from soils with sugarcane cultivation

A study on the composition and physiology of the microbiota of soils subjected to vinasse irrigation may be important in the discovery of products of biotechnological interest, since this residue increases microbial activity in the environments where it is applied. The objective of this work was to carry out the molecular characterization, through the sequencing of the 16S rRNA gene of four bacterial isolates obtained from sugarcane agricultural soils with vinasse management, as well as to evaluate the phosphate solubilization capacity and to relate the results with good practices in agriculture. Isolate LGA01-EV05 showed high sequence similarity with Curtobacterium albidum. The isolate LGA02-EV08 shows similarity with Brevibacillus nitrificans, the isolates LGA03-V20B and LGA04-V20G showed a high degree of similarity among themselves and with Sinomonas soli. Regarding the potential for phosphate solubilization, the four isolates demonstrated efficiency for this function. It was observed that there was no statistical difference between the LGA02-EV08 and LGA04-V20G groups, being the best solubilizing bacteria, with a yield about four times higher than the LGA03-V20B group, the worst among those analyzed.
Effects of the Hazardous Area Response Team Training Program on the Knowledge and Confidence in Operational Skills of Prehospital Emergency Medical Personnel in Thailand: A Quasi-Experimental Study

Background Hazardous areas are places emitting hazardous materials, terrorist- or war-related, which lead to public health risks in developed and developing countries globally. Hence, prehospital emergency medical personnel who work as frontliners should be trained. Patients and Methods Data via pretest, posttest, and questionnaire surveys regarding the HART’s knowledge of and confidence in operational skills were collected using the 5-point Likert scale. The cohort included prehospital emergency medical personnel aged >18 years. The training program comprised lectures, practicals, and examinations and included three subcourses: emergency medicine in the chemical, biological, radiation, and nuclear hazardous area (EM-CBRN) course; Thailand Tactical Emergency Medical Service (TTEMS) course; and cooperation and preparation for disaster (CPD) course. Results The HART’s mean multiple choice question (MCQ) posttest knowledge score (12.80±3.11) was significantly higher (p<0.001) than the mean pretest knowledge score (7.74±3.71) for the EM-CBRN course. The HART’s mean MCQ posttest knowledge score (24.04±2.79) was significantly higher (p<0.001) than the mean pretest knowledge score (14.34±3.92) for the TTEMS course. Further, the HART’s mean MCQ posttest knowledge score (21.03±3.49) was significantly higher (p<0.001) than the mean pretest knowledge score (14.40±5.08) for the CPD course. The HART’s mean confidence in operational skill score for the EM-CBRN course was significantly higher (p<0.001) after training (4.45±0.59) than before training (2.77±0.90). The HART’s mean confidence in operational skill score for the TTEMS course was significantly higher (p<0.001) after training (4.55±0.59) than before training (2.78±0.98). The HART’s mean confidence in operational skill score for the CPD course was significantly higher (p<0.001) after training (4.70±0.41) than before training (3.03±0.90). Conclusion The HART training program significantly affected the HART’s knowledge development and confidence in operational skills, particularly the frontline prehospital emergency medical personnel. Therefore, prehospital emergency medical personnel should undergo training, and learning activities must be developed to reinforce capacity and improve knowledge and confidence.
Sleep, Nutrition, and Injury Risk in Adolescent Athletes: A Narrative Review

This narrative review explores the impact of sleep and nutrition on injury risk in adolescent athletes. Sleep is viewed as essential to the recuperation process and is distinguished as an active participant in recovery through its involvement in growth, repair, regeneration, and immunity. Furthermore, the literature has shown that the sleep of athletes impacts elements of athletic performance including both physical and cognitive performance, recovery, injury risk, and mental well-being. For sleep to have a restorative effect on the body, it must meet an individual’s sleep needs whilst also lasting for an adequate duration and being of adequate quality, which is age-dependent. The literature has suggested that athletes have increased sleep needs compared to those of the general population and thus the standard recommendations may not be sufficient for athletic populations. Therefore, a more individualised approach accounting for overall sleep health may be more appropriate for addressing sleep needs in individuals including athletes. The literature has demonstrated that adolescent athletes achieve, on average, ~6.3 h of sleep, demonstrating a discrepancy between sleep recommendations (8–10 h) and actual sleep achieved. Sleep–wake cycles undergo development during adolescence whereby adaptation occurs in sleep regulation during this phase. These adaptations increase sleep pressure tolerance and are driven by the maturation of physiological, psychological, and cognitive functioning along with delays in circadian rhythmicity, thus creating an environment for inadequate sleep during adolescence. As such, the adolescent period is a phase of rapid growth and maturation that presents multiple challenges to both sleep and nutrition; consequently, this places a significant burden on an adolescent athletes’ ability to recover, thus increasing the likelihood of injury. Therefore, this article aims to provide a comprehensive review of the available literature on the importance of sleep and nutrition interactions in injury risk in adolescent athletes. Furthermore, it provides foundations for informing further investigations exploring the relation of sleep and nutrition interactions to recovery during adolescence.
Anchitherium aurelianense (Mammalia, Equidae) (Cuvier, 1825) dans l'Orléanien (Miocène) de France

The characters of the horse Anchitherium Meyer, 1844 are very conservative. While its dental morphology is quite constant, its postcranial morphology is more variable. Fossil remains from the Orleanian (early to middle Miocene, MN3-MN5) localities of Baigneaux-en-Beauce, Pontlevoy and Thenay, Faluns d'Anjou, Chevilly, Neuville-aux-Bois, Chilleurs-aux-Bois, Chitenay, and Montabuzard (Loire basin) and La Romieu (Aquitaine basin) were studied. Based on their tooth and limb morphology, these fossil remains were assigned to Anchitherium aurelianense aurelianense (Cuvier, 1825). The type specimen of the subspecies comes from Montabuzard. We also studied new fossil remains from the following localities within the Sables de l'Orleanais region (France) : Tavers-les-Paves, and Bois de Maigreville (= Graviers de l'Orleanais). Dental material from Tavers-les-Paves was attributed to A. a. hippoides Lartet, 1851. Remains from the other localities were characterized by mid- to small-sized skeletons and smallish teeth (smaller than the A. a. hippoides teeth from the more recent localities of Sansan and Simorre [France]). Thematerial from the Bunol (Spain) horse was very similar to that of horses of Baigneaux-en-Beauce and other French localities, and was therefore assigned to A. a. aurelianense. This study showed a strong correlation between tooth and postcranial morphologies and size among all the remains. We consider that all the remains from the Sables de l'Orleanais belong to the same species. From a palaeoecological point of view, the characters of A. a. aurelianense suggest a more closed environment than do those of the more recent subspecies from the middle Miocene.
Acceptance, tolerability, and effect of COVID-19 vaccination on disease activity in a cohort of Egyptian systemic lupus erythematosus patients: Real-life experience

Abstract Objective: To assess the tolerance and effects of COVID-19 vaccination in Egyptian patients with systemic lupus erythematosus (SLE), such as incident flare risk, based on the patient’s perspective. Methods: SLE patients were included in this multicenter cross-sectional questionnaire-based analysis. Data included demographic and clinical features, prior COVID-19 infection, vaccine acceptability, type of vaccination, disease status before and after vaccination, and related side effects. Results: The total number of patients included was 230. Ages ranged from 18 to 64 years, disease duration from 1 to 15 years, and 92.6% were females. Only 31.7% of the study population were COVID-infected; most (70.7%) were treated at home, while 1.2% needed ICU. In contrast, 53% of our patients were vaccinated, and 47% were not vaccinated, primarily due to fear of side effects or disease flare. After the first dose of vaccination, 44.1% reported vaccine-related side effects, of which fatigue, fever, myalgia, as well as injection site reaction were the prevalent complications. The highest incidence of side effects was in AstraZeneca (78%), while the least was in Sinopharm (29.6%). 16.3% of vaccinated patients were COVID infected after vaccination, and 88.2% were treated at home. Only 14.6% of the vaccinated population experienced a lupus flare, primarily after the first dose, with no significant difference between the type of vaccine and lupus flares. Conclusion: The acceptance of COVID-19 vaccination among our lupus patients was neutral. The observed adverse effects were comparable to those reported by healthy individuals. Post-vaccination lupus flares were infrequent and unrelated to the vaccine type but rather to the pre-vaccination disease activity state. Keywords: Lupus, COVID, Vaccine, Flare
Short-term and long-term effectiveness of acupuncture and Tuina on knee osteoarthritis: study protocol for a randomized controlled trial

Background The effectiveness of acupuncture and tuina in treating knee osteoarthritis (KOA) is still controversial, which limits their clinical application in practice. This study aims to evaluate the short-term and long-term effectiveness of acupuncture and tuina on KOA. Methods/design This parallel-group, multicenter randomized clinical trial (RCT) will be conducted at the outpatient clinic of five traditional Chinese medicine hospitals in China. Three hundred and thirty participants with KOA will be randomly assigned to acupuncture, tuina, or home-based exercise group with a ratio of 1:1:1. The primary outcome is the proportion of participants achieving a minimal clinically important improvement defined as a ≥ 12% reduction on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain dimension on short term (week 8) and long term (week 26) compared with baseline. Secondary outcomes are knee joint conditions (pain, function, and stiffness), self-efficacy of arthritis, quality of life, and psychological conditions, which will be evaluated by the WOMAC score and the Patient Global Assessment (PGA), and in addition, the respondents index of OMERACT-OARSI, Short Form 12 Health Survey (SF-12), arthritis self-efficacy scale, and European five-dimensional health scale (EQ-5D). Adverse events will be collected by self-reported questionnaires predefined. Clinical trial registration https://www.chictr. org.cn
Optimization of a Food List for Food Frequency Questionnaires Using Mixed Integer Linear Programming: A Proof of Concept Based on Data from the Second German National Nutrition Survey

Food Frequency Questionnaires (FFQs) are important instruments to assess dietary intake in large epidemiological studies. To determine dietary intake correctly, food lists need to be adapted depending on the study aim and the target population. The present work compiles food lists for an FFQ with Mixed Integer Linear Programming (MILP) to minimize the number of foods in the food list. The optimized food lists were compared with the validated eNutri FFQ. The constraints of the MILP aimed to identify food items with a high nutrient coverage in a population and with a high interindividual variability. The optimization was based on data from the second German National Nutrition Survey. The resulting food lists were shorter than the one used in the validated eNutri FFQ.
Analysis of a thermosyphon heat pipe with modified geometry

— In this study, an experimental and 3-dimensional numerical analysis of a thermosiphon heat pipe (THP) using two-phase fluid cycling was performed to model the heat transfer process by evaporation and condensation. R404A refrigerant was chosen as the working fluid for the THP and 50% of the evaporator section was filled with the working fluid. Numerical analysis was performed using ANSYS FLUENT program and VOF method. In the meantime, in order to model the evaporation and condensation process successfully, a UDF code written in C was used and introduced to the fluent program. As a result of the study, it was seen that the temperature values obtained from the experimental and numerical analysis for the evaporator and condenser parts of the THP were in good agreement. As a result of the numerical analyzes carried out in 3D, the contours of the evaporation and condensation process and the heat transfer process are presented visually. The analysis took a total of 200 seconds.
Phase Separation, Reaction Equilibrium, and Self-Assembly in Binary Telechelic Homopolymer Blends

We study a binary blend of telechelic homopolymers that can form reversible AB-type bonds at the chain ends. Reversibly bonding polymers display novel material properties, including thermal tunability and self-healing, that are not found in conventional covalently bonded polymers. Previous studies of reversibly bonding polymer systems have been limited by the computational demand of accounting for an infinite number of possible reaction products in a spatially inhomogeneous, self-assembled structure. We demonstrate that newly developed theoretical models and numerical methods enable the simultaneous computation of phase equilibrium, reaction equilibrium, and self-assembly via self-consistent field theory. Phase diagrams are computed at a variety of physically relevant conditions and are compared with nonreactive analogues as well as previous experimental studies of telechelic polymer blends.
Fusing sensitive degradation features with uncertainty analysis for RUL prediction of rotating machines

Recently, deep learning technology-based neural networks have been adopted for remaining useful life (RUL) prediction of rotating machines. However, there are still some shortcomings: (1) an individual degradation feature cannot sufficiently represent the degradation process, which has an adverse impact on the accuracy of prediction results; (2) most recurrent neural network-based prediction methods have difficulty in quantifying the uncertainty of the forecast results. In this paper, a fusing sensitive degradation features with uncertainty analysis for RUL prediction of rotating machines is proposed. Firstly, the statistical features contained in the vibration signal used to monitor the degradation of rotating equipment are extracted to construct the original feature set. Then, the weight coefficients of the monotonicity, correlation and robustness criteria are determined by the self-adjusting analytic hierarchy process. The sensitive features that describe the degradation process are selected from among the statistical features. Furthermore, the sensitive features are fed into residual networks and gated recurrent unit, and the spatial and temporal correlation of the features are considered to establish the health index (HI). Finally, the fitted HI is input into a Gaussian process regression model, and the prediction results with confidence intervals are obtained. To verify the effectiveness and superiority of the proposed method, two public bearing datasets and three model methods are used for comparative experiments.

Board Diversity and Efficiency of Universities Registered in Kenya: The Role of Funding Sources

The board diversity of institutions plays an integral role in minimizing uncertainty, augmenting knowledge sharing, improving resource utilization, and crafting overall institutional strategy to enhance optimal efficiency. Institutions with more heterogeneous boards are characterized by their ability to attract finances from multiple sources; hence, they are better positioned to be more efficient in their operations. The main aim of this study was to assess the role of funding sources in the association between board diversity and the efficiency of universities registered in Kenya. The study was supported by the agency theory, the human capital theory, the stewardship theory, and the theory of pecking order. The positivist research paradigm anchored the study. A census study of 75 public and private universities in Kenya was conducted using a descriptive longitudinal research approach. The descriptive statistics included calculating the counts, standard deviation, mean, minimum and maximum values, coefficient of variation, kurtosis, and skewness. The fixed effect model was used as the primary estimation technique in inferential statistics. The results established that funding sources partially mediate the association between board diversity and efficiency. The study recommends that for universities to increase efficiency, the boards must make a greater effort to support board diversity, establish the dimensions within the board diversity relevant to efficiency enhancement, and establish multiple funding sources to remain afloat in their operations.
The Genome-Level Survey of the WOX Gene Family in Melastoma dodecandrum Lour.

Though conserved in higher plants, the WOX transcription factors play crucial roles in plant growth and development of Melastoma dodecandrum Lour. , which shows pioneer position in land ecosystem formation and produces nutritional fruits. Identifying the WOX family genes in M. dodecandrum is imperative for elucidating its growth and development mechanisms. However, the WOX genes in M. dodecandrum have not yet been characterized. In this study, by identification 22 WOX genes in M. dodecandrum based on current genome data, we classified family genes into three clades and nine types with homeodomains. We highlighted gene duplications of MedWOX4, which offered evidences of whole-genome duplication events. Promoter analysis illustrated that cis-regulatory elements related to light and stress responses and plant growth were enriched. Expression pattern and RT-qPCR results demonstrated that the majority of WOX genes exhibited expression in the stem. MedWOX13s displayed highest expression across various tissues. MedWOX4s displayed a specific expression in the stem. Collectively, our study provided foundations for elucidating WOX gene functions and further molecular design breeding in M. dodecandrum.
Design Optimization of Wire Arrangement With Variable Relay Points in Numerical Simulation for Tendon-Driven Robots

One of the most important features of tendon-driven robots is the ease of wire arrangement and the degree of freedom it affords, enabling the construction of a body that satisfies the desired characteristics by modifying the wire arrangement.Various wire arrangement optimization methods have been proposed, but they have simplified the configuration by assuming that the moment arm of wires to joints are constant, or by disregarding wire arrangements that span multiple joints and include relay points. In this letter, we formulate a more flexible wire arrangement optimization problem in which each wire is represented by a start point, multiple relay points, and an end point, and achieve the desired physical performance based on black-box optimization. We consider a multi-objective optimization which simultaneously takes into account both the feasible operational force space and velocity space, and discuss the optimization results obtained from various configurations.
Hainosan (painongsan) suppresses the biofilm formation of Porphyromonas gingivalis and Prevotella intermedia in vitro

Porphyromonas gingivalis and Prevotella intermedia are pathogenic bacteria that cause several periodontal diseases such as periodontitis. They frequently form biofilm to protect from threats such as antimicrobial agents. Hainosan (painongsan in Chinese) is a Japanese traditional kampo and traditional Chinese medicine formula used to treat acute and chronic purulent disease. The aim of the present study was to elucidate the mechanism of antibacterial effects such as anti‐biofilm activity, of hainosan extract (HNS) against Porphyromonas gingivalis and Prevotella intermedia.
