Integrated Ionic‐Additive Assisted Wet‐Spinning of Highly Conductive and Stretchable PEDOT:PSS Fiber for Fibrous Organic Electrochemical Transistors

As one of the most prevalently used conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) has been studied for many years. Recently, especially with the development of smart clothing and wearable devices, PEDOT:PSS fiber is becoming the focus of researchers. However, the undesirable conductivity and stretchability hinder its applications. In this work, an integrated ionic‐additive assisted wet‐spinning strategy (IIAWS) is demonstrated to address the existing bottlenecks. The fabricated fiber exhibited an extremely high conductivity of 3573 S cm−1 and stretchability of about 30%. The mechanisms for conductivity enhancement in the entire preparation process are systematically studied and clarified. Furthermore, an all‐solid‐state fibrous organic electrochemical transistor (OECT) device based on the PEDOT:PSS fiber is fabricated with a transconductance of 2.44 mS and impressive bending property.
Dispersion Analysis of Twist-Symmetric Dielectric Waveguides

We propose a circular twist-symmetric dielectric waveguide that is polarization-selective. In the practical implementation of optical fibers, a selective circular polarization is more convenient than its linearly polarized counterpart where previous knowledge of the emitted polarization from the transmitter is unknown. The analysis of the waveguide was conducted with three methods: an eigenmode approach, simulation of a truncated structure, and the so-called multimodal transfer-matrix method (MMTMM). The presented simulations demonstrate that the operational band can be manipulated by tuning the parameters of the structure. Furthermore, the MMTMM allows for a direct and accurate calculation of the attenuation constant of the rejected circular polarization.
An era of brain-computer interface: BCI migration into space

Brain-computer interface's (BCI) potential applications increased tremendously over the past decade. The rising of this new technology is providing promising solutions in the field of aerospace and space exploration. As astronauts face diverse challenges in long-duration spaceflight, BCI can help astronauts deal with complicated tasks with a minimal mental workload. It may provide intelligent communication systems, maximize safety and security, facilitate space discovery missions, and enhance astronauts' overall health and wellbeing. In new ventures such as SpaceX, Starlink, and Neuralink, pioneers adopt futuristic strategies that use BCI as their main anchor. Such efforts are valuable in neuroscience as they will reveal information that will allow neuroscientists to deeper understand the brain's mechanisms.
Psychological Strain and Suicidal Behaviors Among Medical Students in Northwest, China

Abstract Although most studies have shown the psychological strains associated with increased risk of suicidal behaviors, how psychological strains are linked to suicidal behaviors is still unclear. The current study examines the possible mediation effect of psychological distress and hopelessness on the relationship between psychological strains and suicidal behaviors among Chinese medical college students. A cross-sectional survey was conducted from November 2017 to March 2018 involving 5703 medical college students, and the 12-month prevalence of suicidal behaviors was 12.89%. Psychological strains significantly associated with suicidal behaviors, and psychological distress and hopelessness partially explained this relationship. A positive psychological intervention program is needed to buffer the psychological strains, which is a crucial predictor for suicidal behaviors among Chinese medical college students.
Modified three‐dimensional true proportional navigation and its inverse optimal form

A novel three‐dimensional modified true proportional navigation (MTPN) guidance and its inverse optimal form are proposed for the interception of the nonmaneuvering and maneuvering targets, and the nonlinear dynamic characteristics of pursuit situations and target maneuvers are taken into full account. The proposed approach is feasible without knowing any prior information or estimate of the target maneuvers, which are regarded as the unknown disturbance input. Therefore, the TPN‐type guidance is extended to intercept the maneuvering targets with bounded unknown accelerations. Moreover, the explicit physical significance is given for each component of the navigation gain expression of MTPN. The inverse optimal control approach and the input‐to‐state stability are introduced to the MTPN design. Using the MTPN, the homing missile can conduct the terminal homing guidance phase in any particular direction with respect to their nonmaneuvering or maneuvering targets through choosing an appropriate inertial reference coordinate system in practice. Using the proposed schemes, the line‐of‐sight (LOS) rate is globally exponentially stable for nonmaneuvering targets, and is input‐to‐state stability (ISS) for maneuvering targets with bounded unknown accelerations. Performed simulation results have confirmed the effectiveness of the proposed scheme.
Male Infertility, Oxidative Stress and Antioxidants

Within the male reproductive system, oxidative stress (OS) has been identified as prevailing etiology of male infertility. The effects of reactive oxygen species (ROS) on male fertility depend on the dimensions, “modus operandi” of the ROS and the oxido-reduction potential (ORP) of the male reproductive tract. Hereupon, for an adequate response to OS, the cells of our body are endowed with a well-sophisticated system of defense in order to be protected. Various antioxidant enzymes and small molecular free radical scavengers, maintain the delicate balance between oxidants and reductants (antioxidants), crucial to cellular function and fertility. Therapeutic use of antioxidants is an optimal and coherent option in terms of mitigating OS and improving semen parameters. Therefore, recognizing and managing OS through either decreasing ROS levels or by increasing antioxidant force, appear to be a requesting approach in the management of male infertility. However, a clear defined attitude of the experts about the clinical efficacy of antioxidant therapy is still deprived. Prominently, antioxidant such as coenzyme Q10, vitamin C and E, lycopene, carnitine, zinc and selenium have been found useful in controlling the balance between ROS production and scavenging activities. In spite of that, healthy lifestyle, without smoke and alcohol, everyday exercise, reduction of psychological stress and quality well-designed meals, are habits that can overturn male infertility.
Bayesian semiparametric analysis on the relationship between BMI and income for rural and urban workers in China

ABSTRACT This study examines the nonlinear relationship between BMI and earnings for workers in China using Bayesian semiparametric methods. Markov chain Monte Carlo (MCMC) methods are used to obtain the posterior distribution. We stratify the whole sample into four subsamples based on gender and type of residence area. Using longitudinal data from the China Health and Nutrition Survey (CHNS) from 1989 to 2011, we find nonlinear relationship for each group of workers, especially for rural females. For females in both rural and urban areas, being overweight and obese is associated with lower earnings. However, for males in both areas, earnings are not penalized for extra weight.
Effects of a polyherbal formulation on the quality of life and survival of patients with common upper gastrointestinal cancers: A randomized placebo-controlled trial

Objective: Previous clinical trials have suggested that herbal medicines can improve the quality of life (QOL) and survival of cancer patients. This study was aimed to evaluate the effects of a polyherbal compound (PHC, formulated as syrup) consisting of Allium sativum, Curcuma longa, Panax ginseng, and Camellia sinensis on the quality of life (QOL) and survival in patients with upper gastrointestinal cancers. Materials and Methods: A randomized placebo-controlled trial was carried out on patients with esophageal or gastric cancer who had finished their oncological treatments. The patients were randomly assigned to PHC (n=20) or placebo (n=20) group. The PHC group was treated with the PHC for 12 weeks, while the placebo group received 70% sucrose syrup. The QOL was assessed at baseline and after 12 weeks. The patients were followed for up to 24 months to determine overall survival. Results: PHC significantly improved cancer-related symptoms, physical performance, and psychological and social functions of the patients (p<0.05 for all cases). Death occurred in 33 and 22% of cases in the placebo and PHC group, respectively. The mean survival time was 16.8 months (95% CI: 12.8-20.9) in the placebo group and 21.4 months (95% CI: 19.1-23.6) in the PHC group but the difference was not statistically significant. Conclusion: The PHC improved cancer-related symptoms, physical performance, and psychological and social functions in patients with gastrointestinal cancers. It seems that this herbal compound has the potential to be used as a supplement in the management of cancer.
The opioid antagonist naltrexone decreases seizure‐like activity in genetic and chemically induced epilepsy models

A significant number of epileptic patients fail to respond to available anticonvulsive medications. To find new anticonvulsive medications, we evaluated FDA‐approved drugs not known to be anticonvulsants. Using zebrafish larvae as an initial model system, we found that the opioid antagonist naltrexone exhibited an anticonvulsant effect. We validated this effect in three other epilepsy models and present naltrexone as a promising anticonvulsive candidate.
Green infrastructure for the reduction of coastal disasters: a review of the protective role of coastal forests against tsunami, storm surge, and wind waves

ABSTRACT Green infrastructure, utilizing coastal ecosystems, provides a nature-based solution to counteract coastal hazards and rising sea level. Coastal forests, a major type of green infrastructure, are recognized as natural barriers against ocean waves. They can attenuate waves, mitigate erosion, and stabilize shorelines. With growing interests in coastal forests and their function of adapting to future risks, many researchers studied vegetation effects in coastal protection. Yet our limited expertise in quantifying vegetation-induced resistance limits the practical applications. This paper aims to review and categorize the studies related to wave attenuation and mitigation of sediment erosion by coastal forests and identify the potential directions in future works. We first reviewed field observations of extreme tsunami and weather events which showed the effectiveness of coastal forests in reducing wave energy. Next, we covered the studies on wave–vegetation interaction, including mathematical/numerical models and laboratory tests. We categorized the developed models based on different governing equations and introduced how vegetation effects were incorporated. We also discussed the experiments and vegetation models used in laboratory tests. Besides, we highlighted recent studies on the mitigation of coastal erosion. Finally, we recommend the potential directions to quantify the effects of coastal forests on wave attenuation and sedimentation.
An Experimental Study of a Wine Batch Distillation in a Copper Pot Still Heated by Gas

Wine batch distillation in a copper pot still heated directly by combustion is unusual. It is a niche sector. Few studies are available on the subject and even fewer have studied it from a thermal point of view. In a context of ecology awareness and regularly increasing gas taxes, finding less energy consuming and more performing solutions has become necessary. Two methods already exist to recover energy for such pot stills, however improvements could be made. The present study focuses on the heating zone of an experimental pot still. First, a thermal diagnosis based on a nodal model is conducted in transient regime. The major sites of energy expenditure and waste are thus identified and quantified. Results highlight significant losses both in combustion smoke and by conduction to the environment resulting from a limited thermal performance of the system. Proposals are then made to enhance it. For instance, the preheating could be optimized and more thermal waste could be recovered.
Drivers of mobile learning app usage: an integrated perspective of personality, readiness, and motivation

ABSTRACT Mobile phones are now used ubiquitously in everyday life around the world. However, using mobile devices for learning activities (i.e. m-learning) is not as popular as initially expected. This study explores the factors that affect m-learning apps acceptance among mobile phone users and investigates how personality, readiness, and motivation contribute to m-learning acceptance. The results of partial least squares analysis (PLS) with 297 valid samples indicate that conscientiousness and m-learning readiness are critical antecedents of intrinsic motivation and extrinsic motivation, with both motivations affecting intention to use m-learning app systems significantly and positively. Finally, theoretical and managerial implications are presented based on this study’s interesting findings.

Role of Heat Wave‐Induced Biogenic VOC Enhancements in Persistent Ozone Episodes Formation in Pearl River Delta

Regional ozone (O3) pollution is influenced by a combination of anthropogenic sources and biogenic volatile organic compounds (BVOC) emitted from vegetation. Under the influence of warming climate and projected expansion of urban green space, O3 pollution may get worse, especially during heat waves (HWs). However, HW‐induced changes in BVOC and subsequent effects on regional O3 pollution have not been adequately assessed. In this study, we used the Weather Research and Forecasting‐Community Multi‐scale Air Quality models to investigate the formation of a typical O3 episode and quantify the O3 response to BVOC in the Pearl River Delta during a HW in 2017. The results showed that the rate of increase of O3 during the HW was 27.1 µg m−3 °C−1, reflecting the rapid O3 formation under high temperature. Compared with the non‐HW (NHW), gas‐phase chemistry and vertical transport were dominant contributors to O3 formation. Sensitivity experiments indicate that the contribution of BVOC to ground‐level O3 formation in Pearl River Delta was up to 42.1 μg m−3 because BVOC emissions in HW were 430 mol d−1 higher than the NHW. Under northerly winds and strong sea‐land breezes, BVOC and oxidation products from rural areas were transported to downwind VOC‐limited regimes and result in severe O3 pollution owing to intense photochemical reactions and accumulated O3 precursors. These findings point to the essential role of BVOC enhancements induced by HWs to O3 formation and suggest the consideration of BVOC emission potential of planted trees in urban greening strategies for avoiding the offset effects from BVOC.
Evaluation of self-healing performance of concrete containing fly ash and fibres

ABSTRACT Since the existence of cracks reduces the concrete service life, the self-healing ability of concrete has attracted the attention of researchers. In this article, effects of fly ash and steel/polypropylene fibres on the self-healing ability of concrete were investigated separately and together. The cylindrical specimens were pre-cracked by means of a tensile strength test at 28 days. Secondary tensile test was performed immediately after pre-cracking and 28 and 56 days after re-curing in water. Also, to monitor microcracks in concrete after pre-cracking and during the self-healing period, the ultrasonic pulse velocity and permeability tests were conducted. The results showed that 15% fly ash replacement led to 94% reduction in permeability and almost complete recovery in secondary tensile strength after 8 weeks of re-curing. Although the specimen with polypropylene lost lower tensile strength among specimens with fibre immediately after pre-loading (22%), the improvement rate of those during the self-healing period was only 27%.
Below-aspiration performance and risk-taking behaviour in the context of Taiwanese electronic firms: a contingency analysis

ABSTRACT This study combines the behavioural theory and the behavioural agency theory of the firm to investigate managerial risk-taking behaviour at times of below-aspiration performance and the influence of CEO structural power and earnings pressure on subsequent managerial behaviour. By employing the data of publicly listed Taiwanese electronic firms from the period of 2010–2018, this study found that firms tend to make risky choices when their performance is under the aspiration threshold. However, after this relationship was examined with contextual conditions, the study found that CEO structural power and earnings pressure moderate a firm’s risk-taking positively and negatively, respectively. The configurational effect of the two moderators sheds further light on the interactive contextual settings, indicating that CEO structural power outweighs the moderating effect of earnings pressure.
Impact of Herbicide Treatments on the Construction Materials in the Roman Wall of Lugo, Spain (UNESCO World Heritage Site)

Combined laboratory and field research examining the possible alterations caused by herbicide treatments applied to the construction materials (schist and some granite, bound with mortar) in the Roman wall of Lugo (NW Spain), declared a World Heritage site by UNESCO in 2000, was performed in three separate studies in the past 20 years. In the summers of 1998 and 1999, the herbicides glyphosate, sulphosate and glufosinate–ammonium, as well as physical treatments (infrared and burning) were separately applied to different areas of the wall. In the spring of 2016, the oxyfluorfen herbicide Goal Supreme® was applied to test areas. In the winter of 2018, three essential oils, Origanum vulgare L. , Thymus zygis Loefl. ex L. , and Thymus vulgaris L. , were each applied to test areas. Mineralogical modifications in the materials (determined by X-ray diffraction analysis), as well as visible physical changes, such as colour changes, and the appearance of saline residues were evaluated after the treatments. In the 1998/9 trial, glyphosate and both physical treatments triggered changes in the vermiculite clay minerals in the schists, and the physical treatments also caused changes in the kaolinite. None of the treatments caused highly perceptible colour changes. The oxyfluorfen herbicide did not cause any mineralogical alterations in the construction materials, but it did generate an increase in chloride, nitrate and sulphate contents of the granite and a slight darkening of this material. In the most recent study, the only deleterious effect observed was a perceptible increase in lightness and reduction in the yellow component after the application of Thymus zygis Loefl. ex L. essential oil to granite.
Trombosis del seno lateral como complicación de una otitis media aguda o crónica

En este articulo se pretende presentar mediante un proceso de revision bibliografica acerca del tema, los metodos de diagnosis, la ocurrencia, el tratamiento, la morbi-mortalidad e incluso el pronostico en casos de trombosis del seno lateral, misma que puede originarse como complicacion de una otitis media o mastoiditis, debido a diseminacion venosa de la infeccion por la vena emisaria mastoidea o diseminacion directa de la infeccion, tambien puede originarse por la formacion de absceso extradural que ocurre en mas de la mitad de los casos. Su incidencia ha disminuido gracias al tratamiento antibiotico, considerandose actualmente una complicacion muy rara de la infeccion aguda del oido medio, haciendo que se presente con mas frecuencia secundaria a infecciones cronicas con clinica atipica. Dada la variabilidad e inespecificidad de los sintomas de presentacion de la TSL se hace necesario contar con un metodo de diagnostico por imagenes. Actualmente la de mayor especificidad es la RM en estado venoso, la cual puede combinarse con TAC con contraste. Entre las conclusiones destaca lo que sigue a continuacion: Luego de la revision bibliografia del tema podemos concluir que la trombosis del seno lateral es una patologia de instauracion insidiosa y dificil diagnostico, que debemos tener presente siempre como complicacion intracraneal asociada a OMA y/o OMC colesteatomatosa con mastoiditis con caracter subclinico. En la mayoria de individuos existe en cuanto al calibre de venoso cerebral una dominancia derecha por lo que la lesion de este lado produce mayor afectacion del flujo venoso.
New Indirect Tire Pressure Monitoring System Enabled by Adaptive Extended Kalman Filtering of Vehicle Suspension Systems

This paper presents a new indirect tire pressure monitoring system (TPMS) based on adaptive extended Kalman filtering with unknown input (AEKF-UI) estimation of vehicle suspension systems. The suggested methodology is based on the explicit correlation between tire pressure and tire stiffness and is available in real time. AEKF-UI is used to simultaneously estimate the time-varying parameter (tire stiffness) of vehicle suspension systems and the road roughness using an unknown input estimator. Simulation studies demonstrate that the proposed algorithm can simultaneously estimate tire stiffness (i.e., tire inflation pressure) variation and unknown road roughness input. The feasibility and effectiveness of the proposed estimation algorithm are verified through a laboratory-level experiment. This study offers a potential application for an alternative indirect TPMS and the estimation of unknown road roughness used for automotive controller design.
