Published: February 2023

Abstract
The paper studies the surface temperature rise and pulse charge/discharge capacity of batteries with different charge/discharge rates under different temperature conditions. The discharge performance and charge rate characteristics of an automotive lithium-ion battery were investigated. The battery discharge performance tests were conducted under different ambient temperatures and different charge rate conditions to obtain the battery charge voltage curve, charge capacity, and the temperature change pattern of the external surface of the battery during the charging process. Also, internal resistances of the battery cell were measured using the hybrid pulse power characteristic (HPPC). Experimental results show that the battery’s 10% to 90% DOD range shows the excellent pulse charging and discharging ability of the battery, and the temperature change of the battery is much higher at the beginning of the charging process and the end of the discharging process due to the influence of internal resistance.

Authors: Zhang Jifan 
Published: February 2023

Abstract
As the main major equipment in the power plant, the steam turbine has a complex structure and poor operating environment. Its reliability is very important for the power plant. Intelligent fault diagnosis of steam turbines is an important part of the construction of smart power plants. As a complex system, the operation state of a steam turbine may be affected by a variety of faults. Different faults are interconnected and excited each other, which is often caused by the concurrence of other faults due to the occurrence of one fault. The external phenomenon produced is the result of the comprehensive action of many factors. The intelligent fault diagnosis system of steam turbines is based on traditional parameter monitoring and further analyzes on the basis of monitoring to find out the cause of the fault and gives maintenance suggestions. It includes diagnosing the faults that have occurred to prevent further deterioration and predicting the faults that have not occurred to prevent the occurrence of faults so as to achieve the purpose of fault diagnosis, pre-diagnosis, and intelligent maintenance.

Abstract
In order to achieve an efficient collection of wave energy and stable power output, a two-float oscillating flapping-wing wave energy converter is proposed. Based on the hydraulic conversion system of the multi-chamber cylinder, a hydraulic conversion and merging system of the multi-chamber cylinder is created. The composition and working principle of the system, as well as the parameters of the acquisition mechanism, hydraulic conversion and merging system, are determined. AQWA is used to simulate the flapping-wing angular displacement response, and AMESim is used to build the simulation model of the acquisition mechanism, the hydraulic conversion and merging of multi-chamber cylinders, and the power conversion and energy storage system. The research results show that the system can work stably under level 3 and 4 sea conditions, and the input power of the battery is stable at about 46.5kW and 56.5kW, respectively. The rationality and feasibility of the two-float oscillating flapping-wing wave energy converter are verified by simulation.

Published: February 2023

Abstract
Since China entered the era of high-voltage AC and DC hybrid power grids, many high-voltage transmission lines have been successfully constructed. Due to the high voltage and long transmission distance of high-voltage transmission lines, once a fault occurs, it will cause serious losses. The research on the relay protection method of high-voltage transmission lines based on time-frequency analysis is proposed, which has important contribution value to ensure the stable development of the power grid. The fault signal of the high-voltage transmission line is extracted based on time-frequency analysis. The fault transient component of a high-voltage transmission line is detected by decomposing the fault signal characteristics. The phase correlation protection based on the fault transient component is realized to realize the relay protection of the high voltage power transmission line. The simulation results show that the accuracy of the proposed method is 100%, which verifies the reliability of this method.

Optimization of Chenzhuang Combined Station through Pinch Analysis
Authors: Zheng Yong 
Published: February 2023

Abstract
The energy flow relation in the heating and heat exchanging process in a combined station is complicated. The heat exchanging network of Chenzhuang combined station has unreasonable energy utilization. First, pinch analysis for Chenzhuang combined station is performed by selecting pinch temperature differences within a reasonable temperature range. The pinch situation and minimum heating and cooling load are determined through the problem table. Then the energy-saving potential of the heat-exchanging network, which is optimized and retrofitted, is calculated. Finally, according to the results of energy costs and heat exchanger costs, the relationship between minimum pinch temperature difference and costs is plotted, with obtaining the optimal pinch temperature difference. Hereafter, pinch analysis is performed again, and the pinch temperature and energy-saving potential are calculated under the optimal pinch temperature difference. The results show that when the temperature difference of the pinch point is 20°C, the total cost of the corresponding combined station is the lowest, and the energy-saving potential reaches 14.3%.
Drag Reduction Design of Transonic Airfoil Based on Particle Swarm Optimization Algorithm
Authors: Zhao Qinghe 
Published: February 2023

Abstract
The particle swarm optimization algorithm was introduced and the six-hump camelback function problem was verified and tested. The flow field of the RAE2822 airfoil was simulated by the Navier-Stokes equation and compared with the experiment very well. Based on the aerodynamic optimization case of an airfoil, an optimization design and drag reduction design with a lift coefficient fixed were developed. In this problem, geometric constraints and aerodynamic constraints are both involved. A population of 30 individuals was generated. The CST airfoil parameterized method was used to generate the new airfoil, and the dynamic mesh technique was used to update the new mesh. The aerodynamic characteristics of each airfoil was simulated by Navier-Stokes equation and obtain the individual fitness value. A total of 20 iterations of the design were carried out. There was a strong shock wave and a large shock drag in the baseline airfoil transonic flow. The shock strength is obviously weakened after optimization. The pressure drag is obviously reduced, and the lift-drag ratio is increased by 75%.

Abstract
Polyurethane (PU) substrates are biocompatible materials widely used to manufacture endotracheal tubes. However, in common with other biomedical materials, they are liable to the formation of microbial films. The occurrence of pneumonia in intubated patients treated at intensive care units often takes the form of ventilator-associated pneumonia (VAP). The issue relates to the translocation of pathogenic microorganisms that colonize the oropharyngeal mucosa, dental plaque, stomach, and sinuses. New protective materials can provide a more effective therapeutic approach to mitigating bacterial films. This work concerns microcrystalline carbon film containing dispersed silver nanoparticles (μC-Ag) deposited on PU substrates using a physical vapor deposition sputtering process. For the first time, carbon paper was used to produce a carbon target with holes exposing a silver disk positioned under the carbon paper, forming a single target for use in the sputtering system. The silver nanoparticles were well distributed in the carbon film. The adherence characteristics of the μC-Ag film were evaluated using a tape test technique, and electron dispersive x-ray mapping was performed to analyze the residual particles after the tape test. The microbicidal effect of the thin film was also investigated using species S. aureus, a pathogenic microorganism responsible for most infections of the lower respiratory tract involving VAP and ventilator-associated tracheobronchitis (VAT). The results demonstrated that μC-Ag films on PU substrates are promising materials for mitigating pathogenic microorganisms on endotracheal tubes.

Abstract
Among Mediterranean regions, the South-Central Zone of Chile (SCZCh) portrays a landscape where wildfires constantly and historically occur, many times damaging ecosystems, lives and livelihoods. Since 2010, this zone has entered a period of unprecedented drought that has contributed to wildfire rising trends. Wildfire occurrence and intensity in this zone can be associated with three main factors: climate and land cover as conditioning factors, and human activity as a triggering factor. This paper evaluates wildfire hazard for the SCZCh, based on environmental susceptibility to wildfire occurrence, using numerical regional climate and wildfire modeling for the 2002–2005 historical period and for the mid and late 21st-century under the RCP8.5 climate change scenario. Results indicate high skill in matching spatial patterns of fire spot occurrence and density in the historical period, as well as the ability to simulate seasonal behavior in wildfire environmental susceptibility, consistent with national historical statistics. The fire hazard in SCZCh will slightly increase in all seasons for both 2041–2050 and 2091–2100 periods, especially southward, with a long-term spatial homogenization of medium levels of hazard in Central Valley and Coastal Range, between 0 and 1000 m a.s.l. These results combined with the current homogeneous extensive exotic species plantations dominated by inflammable tree species in SCZCh might facilitate the occurrence of large wildfires under the projected 21st-century climate regime.

Published: February 2023

Abstract
Switchable circular dichroism (CD) is in high demand in wireless communication, real-time imaging, etc. At present, the active switching range of CD magnitudes in a nanostructure is relatively narrow. Herein, the giant and reversible CD with large-range modulation is realized by controlling the phase transition of GST (Ge2Sb2Te5) in a double Z-shape array. The demonstrated CD undergoes the large range from −0.85 to 0.85, which is a major advance. The giant CD arises from the polarization-dependent excitations of electric and magnetic dipole resonances. Utilizing the giant and reversible CD, the application for dynamic near-field image display is demonstrated. The reconfiguration capability of our metasurface for large-range switchable CD will promote the prosperity of active chiro-optical devices.
Design and development of IV fluid warming system using TRIZ methodology
Authors: Shrivastava Siddhant , Verma Abhishek , Ramkumar Janakarajan 
Published: February 2023

Abstract
In intravenous (IV) tube infusion therapy, various fluids, such as saline, glucose, blood, and others, are infused into the body via the veins leading to the heart, causing the fluids to circulate throughout the body. The IV fluid is packaged in a flexible plastic-based container, and during therapy, the container is kept in an open environment that could either cool or warm the fluid. The body’s core temperature, which is usually 37 °C, catastrophic drops when this cool intravenous fluid is combined with blood, resulting in hypothermia and other health complications. It can be life-threatening for young newborns, severe patients, and elderly individuals. Nearly 14% of hospitalized patients are hypothermic upon arrival. In this study, a portable IV fluid warming system was made that warms the intravenous fluids before they reach the human body, preventing hypothermia by maintaining the required temperature. The solution was formulated using the TRIZ contradiction matrix. Various processes involved in resolving the conflict via the TRIZ matrix were investigated in depth, and the device was subsequently made employing the ideas. The device consists of an encased heating jacket that can be wrapped all around the IV fluid container to heat the fluid without direct contact, thereby eliminating the risk of contamination. It works on a feedback control system & simplifies temperature regulation desired by the physician. The design was validated via thermal analysis in software, and via experimentation, both the results were within a close tolerance of each other, which proves the design successful. Later, the equipment was certified by an ISO 13485-accredited facility, and currently, testing is ongoing in hospitals under supervision. The developed IV fluid warmer is cost-effective, recyclable, and ergonomically designed for user comfort compared to conventional commercial warmers.
Direct Effect of Life-Course Socioeconomic Status on Late-Life Cognition and Cognitive Decline in the Rush Memory and Aging Project
Authors: Krasnova Anna , Tom Sarah E , Valeri Linda , Crane Paul K , Bennett David A 
Published: February 2023

Abstract
The role of socioeconomic status (SES) across the life course in late-life cognition is unclear. We tested the hypotheses that: 1) High SES in childhood, young adulthood, midlife, and late life have independent causal effects on higher cognition level and slower cognitive decline; 2) Compared with stable low SES (referent), stable high SES has the largest estimated effect for higher cognition level and slower decline among life-course SES combinations. The Rush Memory and Aging Project enrolled 1,940 dementia-free older adults in northeastern Illinois (1997–2018). We used inverse probability–weighted marginal structural models to estimate the joint and independent effect of each life-course SES on global and domain-specific cognition. A total of 1,746 participants had, on average, 6 years of follow-up. High SES at each life-course stage starting in young adulthood had a protective estimated effect on global and domain-specific cognition intercepts. Compared with consistently low SES, consistently high SES (β = 0.64, 95% confidence interval: 0.48, 0.93) and high SES beyond childhood (β = 0.64, 95% confidence interval: 0.47, 0.83) had the largest benefit for global cognition intercepts. None of the life-course SES measures influenced rate of global or domain-specific decline. Additional understanding of life-course SES components influencing cognitive level is warranted.
A cofunctional grouping-based approach for non-redundant feature gene selection in unannotated single-cell RNA-seq analysis

Published: February 2023

AbstractFeature gene selection has significant impact on the performance of cell clustering in single-cell RNA sequencing (scRNA-seq) analysis. A well-rounded feature selection (FS) method should consider relevance, redundancy and complementarity of the features. Yet most existing FS methods focus on gene relevance to the cell types but neglect redundancy and complementarity, which undermines the cell clustering performance. We develop a novel computational method GeneClust to select feature genes for scRNA-seq cell clustering. GeneClust groups genes based on their expression profiles, then selects genes with the aim of maximizing relevance, minimizing redundancy and preserving complementarity. It can work as a plug-in tool for FS with any existing cell clustering method. Extensive benchmark results demonstrate that GeneClust significantly improve the clustering performance. Moreover, GeneClust can group cofunctional genes in biological process and pathway into clusters, thus providing a means of investigating gene interactions and identifying potential genes relevant to biological characteristics of the dataset.

The use of ultrasound and magnetic resonance imaging in the management of hidradenitis suppurativa: a narrative review
Authors: Mendes-Bastos Pedro , Martorell Antonio , Bettoli Vincenzo , Matos António P , Muscianisi Elisa , Wortsman Ximena 
Published: February 2023

Abstract
Hidradenitis suppurativa (HS) is a chronic, inflammatory follicular skin disease that frequently affects the apocrine gland-bearing skin of the axillary, inguinal and anogenital regions. HS has a significant impact on the psychosocial health and quality of life of patients. Diagnosis of HS is typically clinical, and relies on the ability of physicians to recognize the signs of HS. However, lesions may present at the dermal and subcutaneous skin layers, which cannot be diagnosed by clinical examination alone. Further, the complexity of the clinical presentation of HS can lead to misdiagnosis and delay of diagnosis and appropriate treatment. Imaging is an important tool that can address these issues by detecting inflammatory activity and the early subclinical and dermal features of HS, and accurately characterizing lesional morphology, thereby informing on optimal therapeutic strategies. Overall, imaging is a key tool that can be used in conjunction with clinical examination to improve the management of HS by providing additional information to physicians, and thus optimize clinical decision making.
In this narrative review, we provide an overview of the general role of imaging in the management of HS, and we illustrate HS-specific applications of two pertinent imaging modalities, ultrasound and magnetic resonance imaging. Finally, based on the literature, we summarize their uses in HS and provide considerations relating to standardizing the practise of ultrasound and effectively implementing the use of imaging in the management of HS.
Monkeypox: a review of the 2022 outbreak
Authors: Lim Eleanor Y , Whitehorn James , Rivett Lucy 
Published: February 2023

AbstractIntroductionIn May 2022, the World Health Organisation declared a multi-country monkeypox outbreak in non-endemic countries following cases reported from 12 member states that were not endemic for monkeypox virus.Sources of dataPubmed search.Areas of agreementThe virology, epidemiology, transmission, incubation and aspects of infection control are described. Clinical features of previous and current outbreaks are described, with growing observations that the current outbreak presents with clinical features distinct from previous outbreaks.Areas of controversyThere are variations in clinical presentations seen in the current outbreak that have not been seen in prior outbreaks. More research is needed to investigate the reasons for these differences.Growing pointsThe higher numbers of HIV-positive patients in the current outbreak has allowed better description of the disease in patients co-infected with HIV and monkeypox. The absence of more severe symptoms in HIV-positive patients in the current outbreak could possibly be due to the fact that most of these patients had well-controlled HIV, although further characterization of this cohort of patients would be useful.Areas for developing researchCurrent treatment and vaccination options have been extrapolated from studies of other Orthopox viruses. There remains a need for more data on the safety and efficacy of these options in the context of monkeypox infections.
