Authors: N. Gabriel-Job , U. Azubogu 
Published: April 2022

Aims: To determine the bullying experience among secondary school students in Obio Akpor Local Government Area of Rivers State, Nigeria.
Study Design: A cross sectional study was conducted among 1860 participants aged 10-19 years.
Place and Duration of Study: The study was conducted in nine co-educational secondary schools in Obio Akpor Local Government Area (LGA) of Rivers State, Nigeria over a six month period (January 2021 – June 2021)
Materials and Method: Bullying behavior was assessed using a questionnaire designed by the researchers. Descriptive and inferential statistics were carried out. Statistical significance was set at a p-value <0 .05.
Results: The mean age of the study participants was 14.25±1.85 years and the male to female ratio was 1.1:1. Nearly all of the students (98.9%) had heard of bullying. Furthermore, 56.6% of participants were victims of bullying, 32.4% were perpetrators and 11.0% were neither victims nor perpetrators of bullying. The most common bullying behaviors known to the students were: physical assaults (19.6%) and “taking things forcefully from others” (19.3%). Factors significantly associated with both bullying victimization and perpetration included; age greater than 14 years, male gender and low socio-economic status (p<0.001). Furthermore, bullying perpetration was more common in senior school students (p<0.001) while a greater proportion of junior school students were victims of bullying (p<0.001).
Conclusion: Bullying behavior remains a significant social problem among secondary school students in our society. It has deleterious physical and psychological effects on both the victim and the perpetrator. Greater efforts are required from all stakeholders to eliminate this negative trend.

Published: April 2022

AbstractThe utilization of various environmental renewable energy is an important way to achieve carbon peak and carbon neutrality. Most current multisource energy harvesters are achieved by integrating several single generators with independent structures and discrete mechanisms. Here, a multisource energy harvester (MEH) is proposed which can simultaneously collect raindrop, solar, and thermal energy with coupling structure and multiplexing mechanism. The MEH uses metal to connect n‐type and p‐type silicon coated with indium tin oxide (ITO) into a π‐type structure, and then cover the ITO surface with a layer of PTFE film. With this compact and coupled configuration, the triboelectric, photovoltaic, and thermoelectric effects can all contribute to the power generation by the multiplexed function elements and communal electrodes. The average power density of the MEH can reach 4.44 mW m−2. Moreover, the power supply ability of the array MEH has been demonstrated by charging capacitors and driving electronics. This work designed a highly integrated multisource energy harvester, providing a promising solution for energy supply in complex natural environments.

Published: April 2022

AbstractIn a high‐mix and low‐volume manufacturing facility, heterogeneous jobs introduce frequent reconfiguration of machines which increases the chance of unplanned machine breakdowns. As machines are often nonidentical and their performance degrades over time, it is critical to consider the heterogeneity and non‐stationarity of the machines during scheduling. We propose a reinforcement learning‐based framework with a novel sampling method to train the agent to schedule heterogeneous jobs on non‐stationary unreliable parallel machines to minimize weighted tardiness. The results indicate that the new sampling approach expedites the learning process and the resulting policy significantly outperforms static dispatching rules.

Published: April 2022

AbstractIn recent years, piezoresistive pressure sensors with superhydrophobicity have aroused considerable attention. In addition, to comply with “sustainable development” strategy, the sensors fabricated with eco‐friendly materials is of great theoretical and practical significance. Herein, tannic acid (TA) was first absorbed on the surface of poly(lactic acid) (PLA) nonwoven fabric by simple dipping method. After that, silver (Ag) particles were in situ generated on the surface to construct roughness with the reduction role of TA by immersing the fabric into silver nitrate aqueous solution. Finally, n‐lauryl mercaptan was grafted on the Ag particles via Ag–S bonds to provide low surface energy, and a conductive and superhydrophobic PLA (CSPLA) nonwoven fabric was fabricated. The obtained CSPLA nonwoven fabric had a high water contact angle of 150.3°. The fabric‐based piezoresistive pressure sensor possessed high sensitivity, fast response, good stability, and excellent reusability, and was successfully applied for detecting various human motions including voice recognition, joint bending, stomping, walking, and jumping. The fabricated sensor has great application potential in the fields of touchable displays, electronic skins, intelligent robotics, and wearable devices.

Published: April 2022

AbstractTo simultaneously improve the flame retardancy, smoke suppression, mechanical properties, and dielectric properties of epoxy resin (EP), a series of polyhedral oligomeric silsesquioxane containing vinyl and epoxy groups (EV‐POSSs) was designed and successfully synthesized. The results of Fourier transform infrared (FT‐IR), Nuclear Magnetic Resonance (NMR) and mass spectra indicated that the EV‐POSSs possessed two main cage structures, T10 and T12. The epoxy groups attaching to POSS connected the polymer main chains, forming higher crosslinking‐density networks. The self‐polymerization of vinyl groups under high temperatures improved the mechanical property and the quality of char residues. Based on our study, the introduction of EV‐POSSs can enhance the flame retardancy, smoke suppression, mechanical and dielectric properties. Compared with pure EP, the dielectric constant of EP containing 2 wt% EV‐POSS dropped from 3.9 to 3.6 at 106 Hz. In addition, with the 10 wt% EV‐POSSs, the peak of heat release rate and total smoke production also reduced by 50.7% and 36.7%, respectively. Most notably, the maximum smoke density declined by 44.8% due to the EV‐POSSs simultaneously containing epoxy and vinyl groups show comprehensive enhancement and occupy spacious applications.

AbstractNo reports of vasovagal reflex activity during robotic‐assisted laparoscopic hysterectomy (RALH) exist. We present a case of a woman who underwent a RALH for a uterine myoma with uterine adenomyosis. A lack of tactile feedback and a traction force sensor create unique risks of robot‐assisted surgery. Anesthesiologists should be aware of these risks.
A simplified implementation of NLSPWM control strategy for SqZS inverter via model‐driven processor programming method
Authors: Noroozi Meraj , Haghjoo Farhad , Javadi Hamid , Zolghadri Mohammad Reza 
Published: April 2022

AbstractThe transformerless single‐phase semi‐quasi‐Z‐source inverter (SqZSI) has a nonlinear gain curve and requires nonlinear sinusoidal pulse width modulation (NLSPWM) to achieve sinusoidal voltage at the output AC terminal. Although the SqZSI provides some advantages, for example, leakage current elimination, doubly grounded, low volume, and low cost, it needs nonlinear modulation control. The NLSPWM is relatively complex among single‐phase modulation methods and it is considered a disadvantage for this topology, so this paper presents a model‐driven processor programming method that facilitates the implementation of NLSPWM. The developed programming method utilizes a Blockset environment in MATLAB/Simulink to implement NLSPWM, and then the obtained model is compiled and directly uploaded to the ARM Cortex‐M4‐based STM32F4 processor. In this approach, there is no need for coding in C programming language, and only the Simulink mathematical blocks are used so it simplifies the implementation process. The same Simulink model used to model the inverter control is slightly edited for implementation, which accelerates the debugging cycle. Experimental results of 100 W SqZSI confirm the desired and accurate performance of this low‐cost method. The qualitative comparison of the processor programming methods and the performance comparison of the developed SqZSI based on this approach verify the simplicity of implementation.

ABSTRACTBackgroundThe aggressiveness of renal cell carcinoma (RCC) associated with Xp11.2 translocation/TFE3 gene fusion (Xp11.2 translocation RCC [Xp11.2 tRCC]) is age‐dependent, which is similar to the overall trend of reproductive endocrine hormones. Therefore, this study focused on the effect and potential mechanism of androgen and androgen receptor (AR) on the progression of Xp11.2 tRCC.MethodsThe effects of androgen and AR on the proliferation and migration of Xp11.2 tRCC cells were first evaluated utilising Xp11.2 tRCC cell lines and tissues. Because Transcription factor enhancer 3 (TFE3) fusion proteins play a key role in Xp11.2 tRCC, we focused on the regulatory role of AR and TFE3 expression and transcriptional activity.ResultsWhen Xp11.2 tRCC cells were treated with dihydrotestosterone, increased cell proliferation, invasion and migration were observed. Compared with clear cell RCC, the positive rate of AR in Xp11.2 tRCC tissues was higher, and its expression was negatively associated with the progression‐free survival of Xp11.2 tRCC. Further studies revealed that AR could positively regulate the transcriptional activity of TFE3 fusion proteins by small ubiquitin‐related modifier (SUMO)‐specific protease 1, inducing the deSUMOylation of TFE3 fusion. On the other hand, UCHL1 negatively regulated by AR plays a role in the deubiquitination degradation of the PRCC‐TFE3 fusion protein. Therefore, the combination of the AR inhibitor MDV3100 and the UCHL1 inhibitor 6RK73 was effective in delaying the progression of Xp11.2 tRCC, especially PRCC‐TFE3 tRCC.ConclusionsAndrogen and AR function as facilitators in Xp11.2 tRCC progression and may be a novel therapeutic target for Xp11.2 tRCC.The combined use of AR antagonist MDV3100 and UCHL1 inhibitor 6RK73 increased both the SUMOylation and ubiquitination of the PRCC‐TFE3 fusion protein

AbstractIntroductionThe levels of many blood proteins are associated with Alzheimer's disease (AD) or its pathological hallmarks. Elucidating the molecular factors that control circulating levels of these proteins may help to identify proteins associated with disease risk mechanisms.MethodsGenome‐wide and epigenome‐wide studies (nindividuals ≤1064) were performed on plasma levels of 282 AD‐associated proteins, identified by a structured literature review. Bayesian penalized regression estimated contributions of genetic and epigenetic variation toward inter‐individual differences in plasma protein levels. Mendelian randomization (MR) and co‐localization tested associations between proteins and disease‐related phenotypes.ResultsSixty‐four independent genetic and 26 epigenetic loci were associated with 45 proteins. Novel findings included an association between plasma triggering receptor expressed on myeloid cells 2 (TREM2) levels and a polymorphism and cytosine‐phosphate‐guanine (CpG) site within the MS4A4A locus. Higher plasma tubulin‐specific chaperone A (TBCA) and TREM2 levels were significantly associated with lower AD risk.DiscussionOur data inform the regulation of biomarker levels and their relationships with AD.

Oxidative Stability of Oil Obtained from a Low‐Erucic Acid Pennycress (Thlaspi arvense L.) Mutant with Potential for Food Use
Authors: Buck Sabrina P. , Pegg Ronald B. , Tyl Catrin 
Published: April 2022

AbstractThe oilseed cover crop field pennycress (Thlaspi arvense L.) can be grown during the off‐season for summer crops such as corn and soybeans. However, high erucic acid contents make oil from wild‐types unsuitable for human consumption. Recent breeding efforts now offer a mutant strain (fae1‐rod1 pennycress) with an altered fatty acid composition. In this study, fae1‐rod1 pennycress oil is assessed for its fatty acid profile and tocopherol contents using gas chromatography and normal phase high‐performance lipid chromatography, respectively. Oils are incubated at 30, 40, and 50 °C, and changes in the peroxide value (PV), para‐anisidine value (pAV), and free fatty acid (FFA) content are monitored. FFA contents of all samples remained <1% throughout the incubation period. PVs and pAVs rapidly increase in oils stored at 50 °C. The pAVs of oils stored at 40 °C only differ to those of fresh oil after day 15 and are significantly lower than of oil stored at 50 °C throughout storage. PVs remain <15 when stored at 30 °C up to day 54. Pseudo‐first order rate constants to model PV increase are used to generate an Arrhenius plot. The activation energy is estimated as 68 kJ mol−1, comparable to other culinary oils.Practical applications: There is interest in cultivating oil from pennycress seeds for use in foods. Its cultivation could have environmental benefits, e.g., reduce soil erosion, improve nitrogen sequestration, and provide nutrients for pollinators in the spring. However, the wild‐type strain is high in erucic acid, which potentially elicits toxic effects when ingested. Fae1‐rod1 mutant strains contain only traces of erucic acid, but little is known about pennycress oils in general and characteristics related to food use of fae1‐rod1 oils in particular. To the best of the authors’ knowledge, this is the first study predicting fae1‐rod1 storage stability. The data reported here can be used by processors and consumers to estimate the time interval during which cold‐pressed fae1‐rod1 pennycress oil can be expected to maintain its quality attributes at ambient temperature, provided it is stored appropriately, e.g., protected from light.

Published: April 2022

AbstractObjectiveTo assess: (1) the acute effects of smoked marijuana (MJ) on negative attentional bias (NAB), (2) moderation of these effects by positive versus neutral alternatives, and (3) the associations of tetrahydrocannabinol (THC)‐induced changes in NAB with changes in affect.MethodsFourteen MJ users (1–4 uses/wk) smoked a THC cigarette on 1 day and a placebo cigarette on the other counterbalanced day. After smoking, participants freely gazed back and forth at a series of two side‐by‐side pictures pairs presented for 3000 ms (one negative, while the other was either positive or neutral) while eye gaze was tracked.ResultsThe effects of THC relative to placebo varied across time such that THC increased NAB during the early temporal component of threatening picture viewing, 333–858 ms after dual‐picture onset, regardless of alternative picture valance. However, contrary to the attentional bias‐causes affect hypothesis, during the early viewing phase THC‐enhanced positive affect (PA) correlated positively with THC‐induced NAB. In contrast, during the late phase (891–3000 ms) THC‐enhanced PA did not correlate significantly with NAB, though THC‐induced negative affect (NA) change did correlate positively with THC‐induced change in NAB in the positive alternative condition.ConclusionsWe replicated findings of others showing that THC can enhance NAB during the early stages of threatening picture viewing. We extended previous results by demonstrating the THC‐induced NAB is associated with increased PA during initial threat viewing, but with increased NA during later processing if positive alternatives are present.
