Two extraordinary troglobitic species of Allokoenenia (Eukoeneniidae: Palpigradi) from Brazil: first records of this initially monotypic genus more than a century after its description
Authors: Souza Maysa Fernanda Villela Rezende , Ferreira Rodrigo Lopes 
Published: January 2022

The diversity of Palpigradi is not evenly distributed among its different branches. The widespread genus Eukoenenia includes 80% of the species, while the other genera are poorly known. Allokoenenia certainly is the most understudied genus because it is represented only by the African species Allokoenenia afra Silvestri, 1913. Its description is short and does not include many features depicted in modern taxonomy of Palpigradi. In this paper, we describe two troglobitic species of Allokoenenia, report the occurrence of a third species represented by an immature specimen from Brazilian caves, and provide brief notes on the morphology of A. afra. Allokoenenia canhembora sp. nov., A. stygia sp. nov., and Allokoenenia sp. differ from A. afra by several morphological features, including more elongated appendages and a greater number of blades on lateral organs. Thus, they are considered troglomorphic. These new species are vulnerable to extinction because they are endemic to a single or few caves directly impacted by mining activities and groundwater exploitation. This study represents the first step for the conservation of these species and their habitats, since Brazilian caves with rare troglobites cannot be irreversibly impacted. Also, it brings important contributions on the distribution and morphology of this enigmatic genus.

Published: January 2022

La especie Basella alba se conoce popularmente como bertalha india y se consume ampliamente en forma de ensaladas, por ejemplo. El objetivo de este estudio fue evaluar las etapas iniciales de crecimiento y la producción de metabolitos secundarios en diferentes sustratos. Transcurridos 90 días desde el inicio de la plantación (pleno sol), en suelo arenoso mezclado con diferentes sustratos, se determinó el efecto de los sustratos sobre el crecimiento y producción de metabolitos secundarios en las hojas. Los resultados indicaron que el tratamiento con la adición de 70% de vermicompost indujo el mayor crecimiento y la mejor concentración de compuestos fenólicos y flavonoides. Sin embargo, la mayoría de los tratamientos dieron como resultado la producción de heterósidos cardiotónicos, que pueden causar problemas de salud.
The species Basella alba is popularly known as Indian bertalha and is widely consumed in the form of salads, for example. Due to its potential for use, the objective of this study was to evaluate the initial stages of growth and the production of secondary metabolites in different substrates. After 90 days from the beginning of planting (full sun), in sandy soil mixed with different substrates, the effect of substrates on growth and the production of secondary metabolites in leaves was determined. The results indicated that the treatment with the addition of 70% of vermicompost induced the highest growth and the best concentration of phenolic and flavonoid compounds. However, most of the treatments resulted in the production of cardiotonic heterosides, which can cause health problems.

Published: January 2022

Background: Hydro-pneumothorax is a rare variant of pneumothorax. It occurs when both free fluid and air is present within the pleural space. The goal of the treatment is to relieve the pressure on the lung, allowing it to re-expand. Treatment options may involve solely observation or needle aspiration or intercostal tube drainage (ICD), along with antibiotic cover, all of this anchored with physiotherapeutic management.
Case presentation: A 54 years old male visited hospital with complaints of dyspnea (MMRC grade II), dry cough and high-grade fever since one month along with a history of chronic alcohol consumption and tobacco chewing since more than 10 years.
Investigations: Laboratory investigations include Chest X-ray which showed fairly large opacities with fluid level in right side. The costo-phrenic angle on the right side was obliterated, multiple small patchy opacities are also seen in right lower zones. Along with these findings, there was contralateral mediastinal shift.
Treatment: Physiotherapy intervention included patient education, breathing retraining, airway clearance techniques, positioning, walking program with supplemented oxygen and psychological support. Outcome measures have shown improvement in functional independence and performance of activities of daily living.
Conclusion: Physiotherapy management showed efficient results in improving the lung function, quality of life, inducing relaxation and early return to pre-disease life in patient with hydro pneumothorax.

Published: January 2022

AbstractA male with C7 complete tetraplegia participated in 14 weeks of body weight supported treadmill training (BWSTT) combined with spinal cord epidural stimulation (SCES), 4 weeks of no intervention, and two more weeks of BWSTT + SCES. The participant presented with unstable resting seated blood pressure (BP; 131/66 mmHg). After retrospective analysis, resting systolic BP decreased and diastolic BP increased, yielding a safe mean arterial BP. There was a fivefold increase in BWSTT bouts per session, and percentage of body weight support decreased to 69%. BWSTT + SCES safely and effectively regulated resting BP and mitigated symptoms of orthostatic intolerance. These effects were not maintained after 4 weeks without training.
Decentralized adaptive formation control based on sliding mode strategy for a class of second‐order nonlinear unknown dynamic multi‐agent systems
Authors: Zhu Jiahao , Wen Guoxing , Li Bin 
Published: January 2022

AbstractThis article investigates a decentralized adaptive sliding mode formation control (SMFC) based on the leader–follower formation strategy for a class of second‐order nonlinear unknown dynamic multi‐agent systems. Unlike the first‐order multi‐agent formation, the second‐order formation needs to control not only the position but also the velocity, therefore it is more challenging and interesting. In order to handle the unknown dynamic problem, the adaptive neural network (NN) is employed to approximate the unknown dynamic function. Since every agent is required to directly communicate with leader agent, the adaptive NN law can be trained more sufficient. Moreover, in the control design, because a continuous proportional function is introduced to replace the discontinuous switching signal of the traditional sliding mode method, the chattering phenomenon that is a stubborn shortcoming of sliding strategy is effectively suppressed. According to Lyapunov stability analysis, it is proven that the proposed method can fulfill the control task. Finally, a numerical simulation example is executed to demonstrate the performance of the proposed controller.
Manipulating Interfacial Thermal Conduction of 2D Janus Heterostructure via a Thermo‐Mechanical Coupling
Authors: Ren Kai , Qin Huasong , Liu Huichao , Chen Yan , Liu Xiangjun , Zhang Gang 
Published: January 2022

Abstract2D Janus transition metal dichalcogenide (TMD) semiconductor materials have attracted great interest for their potential applications. Because of the increased requirement for thermal management in 2D devices with single‐atom thickness, a fundamental understanding of interfacial thermal conduction (ITC) has emerging significance. In this work, the ITC of in‐plane heterostructures constructed using MoSSe and WSSe is reported. In addition to the interface connected normally by MoSSe and WSSe with the same type of chalcogen atoms are on the same side of left and right sections, inversional interface by rotation of 180° of WSSe is also considered, in which S atoms are on the opposite side of the left and right sections. Interestingly, the ITC in the normally connected heterostructure is found to be almost twice as much as that in the inversely connected heterostructure. The unusually large change in ITC is attributed to the bending curvature and additional discontinuity in the inversely connected heterostructure. Euler–Bernoulli beam model gives further insight into the origin of such interface bending. The findings offer the very first insight into the phonon transport in Janus heterostructures, and benefit thermal management of 2D devices based on Janus monolayers.

Published: January 2022

AbstractBroadband emission with a large Stokes shift is of interest for applications in solid‐state lighting. Such emission is often achieved with self‐trapped excitons; however, in reduced‐dimensional perovskites, high‐performance self‐trapped emission has, until now, been widely observed only in lead‐based materials. Here, the synthesis in an air ambient of reduced‐dimensional Sn‐based perovskite phosphors R2 + xSnI4 + x [R = octylammonium (OTA), hexylammonium (HA) or butylammonium (BA)] is reported, an advance achieved by tailoring the synthesis of the Ruddlesden‐Popper 2D perovskites R2SnI4. The lead‐free R2 + xSnI4 + x phosphors have broadband self‐trapped emission with over 80% photoluminescence quantum yield (PLQY) and more than a 150 nm Stokes shift. White‐light‐emitting diodes (WLEDs) based on OTA2 + xSnI4 + x phosphors exhibit warm‐white emission (correlated color temperature = 2654K) suited to home lighting, and a CRI of 92, among the best for Pb‐free perovskite WLEDs reported to date.

AbstractAlthough neurotransmitters are key substances closely related to evaluating degenerative brain diseases as well as regulating essential functions in the body, many research efforts have not been focused on direct observation of such biochemical messengers, rather on monitoring relatively associated physical, mechanical, and electrophysiological parameters. Here, a bioresorbable silicon‐based neurochemical analyzer incorporated with 2D transition metal dichalcogenides is introduced as a completely implantable brain‐integrated system that can wirelessly monitor time‐dynamic behaviors of dopamine and relevant parameters in a simultaneous mode. An extensive range of examinations of molybdenum/tungsten disulfide (MoS2/WS2) nanosheets and catalytic iron nanoparticles (Fe NPs) highlights the underlying mechanisms of strong chemical and target‐specific responses to the neurotransmitters, along with theoretical modeling tools. Systematic characterizations demonstrate reversible, stable, and long‐term operational performances of the degradable bioelectronics with excellent sensitivity and selectivity over those of non‐dissolvable counterparts. A complete set of in vivo experiments with comparative analysis using carbon‐fiber electrodes illustrates the capability for potential use as a clinically accessible tool to associated neurodegenerative diseases.
Unconventional Metallicity in Graphene Nanoribbons with Armchair Edges
Authors: López‐Urías Florentino , Ortiz‐Medina Josué 
Published: January 2022

AbstractUsing first‐principles density functional theory calculations, 1D armchair graphene nanoribbons (AGNRs) and graphene with an extended line defect (ELD) mimicking a grain boundary (GB) are investigated. Two AGNRs with n and m indices are laterally coupled, generating an ELD with alternated four‐ and eight‐membered carbon rings. Band structure, electronic density of states, wave functions, scanning tunneling microscope image, and quantum transport are analyzed. Unlike the conventional semiconducting behavior of AGNRs, the authors demonstrated that AGNRs with a 4‐8‐ELD exhibit a metallic behavior for n = m = 3p + 2 (p ≥ 0). They further demonstrate that graphene with 4‐8‐ELDs is metallic compared to the semi‐metallic behavior shown by the pristine graphene. Additionally, they investigate the effect of a single vacancy placed at the 4‐8‐ELDs on the electronic properties of AGNRs. The present investigation provides a theoretical basis to tailor graphene structures with possible applications in electronic devices.
Research on Fractal Model of Load Distribution and Axial Stiffness of Planetary Roller Screw Mechanism Considering Surface Roughness and Friction Factor
Authors: Du Xing , Chen Bingkui , Liu Rongrong , Li Chaoyang 
Published: January 2022

AbstractThe effects of surface roughness and material properties of the planetary roller screw mechanism (PRSM) on the axial stiffness and load distribution are rarely studied. In this paper, the load distribution model is presented by incorporating into friction factor and surface microtopography. The microcontact model is built by considering elastic and plastic regimes to calculate the total actual contact area. Moreover, the load distribution model is modified by introducing surface microcontact coefficient. Then, the influences of the nut position, fractal dimension, fractal roughness, friction factor, axial load, and material yield strength on the axial stiffness and load distribution are studied in detail. The numerical results show that the axial stiffness rises with the increment of the nut position, axial load, fractal dimension, and yield strength, and reduces with the fractal roughness and friction factor increasing. In addition, the uniformity of the load distribution increases with the increment of the fractal roughness, and drops with the increase of the fractal dimension and material yield strength. This investigation lays the foundation for the design, manufacturing, and use of the PRSM.

Published: January 2022

AbstractMultifunctional electronic skins have attracted considerable attention for soft electronics including humanoid robots, wearable devices, and health monitoring systems. Simultaneous detection of multiple stimuli in a single self‐powered device is desired to simplify artificial somatosensory systems. Here, inspired by the structure and function of human skin, an ultrasensitive self‐powered multimodal sensor is demonstrated based on an interlocked ferroelectric copolymer microstructure. The triboelectric and pyroelectric effects of ferroelectric microstructures enable the simultaneous detection of mechanical and thermal stimuli in a spacer‐free single device, overcoming the drawbacks of conventional devices, including complex fabrication, structural complexity, and high‐power consumption. Furthermore, the interlocked microstructure induces electric field localization during ferroelectric polarization, leading to enhanced output performance. The multimodal tactile sensor provides ultrasensitive pressure and temperature detection capability (2.2 V kPa−1, 0.27 nA °C−1) over a broad range (0.1–98 kPa, −20 °C < ΔT < 30 °C). Furthermore, multiple simultaneous stimuli can be distinguished based on different response times of triboelectric and pyroelectric effects. The remarkable performance of this sensor enables real‐time monitoring of pulse pressure, acoustic wave detection, surface texture analysis, and profiling of multiple stimuli.
