Published: July 2022

A 7-year-old boy presented 6 weeks after open reduction and crossed Kirschner wire (K-wire) fixation of a supracondylar humerus fracture. Previous treatments had restored skeletal anatomy without documented complications. However, the patient would not move the entire arm, including his forearm and hand. Any passive movement led to anxious adverse reactions, and there was partial numbness of all fingers. After intensive physio- and occupational therapy supported by nerve stimulation and psychological counseling, anxiety-related functional deficits of the shoulder and elbow resolved to reveal the severe Volkmann contracture of the right hand developed fully. Electroneurography, X-ray, magnetic resonance imaging of the forearm, and ultrasonography showed nonfunctional ulnar and a partially disturbed radial motor nerve distal to the elbow along with damaged flexor muscles of the forearm after compartment syndrome. In addition, damage to the median nerve at the elbow level was diagnosed. After intense conservative therapy, we partially resected fibrotic fascia of the superficial flexor compartment, freed ulnar and median nerves, and performed staircase-like releases of tendons and tenotomies. We achieved a full range of motion of all fingers and markedly improved the range of motion of the wrist. The Disabilities of the Arm, Shoulder and Hand scores for function improved from 80 to 16 at the 2-year follow-up postoperatively, but some impairments of fine motor function persisted. Subtle symptoms of a developing compartment syndrome need to be recognized. Overlooked and untreated, a consecutive Volkmann contracture can turn the extremity nonfunctional. Intensive physical, psychological, and surgical therapy in a specialized center can restore function but requires endurance and perseverance throughout the lengthy recovery.
High-Resolution Transperineal Ultrasound in Anorectal Malformations—Can We Replace the Distal Colostogram?
Authors: Palmisani Francesca , Krois Wilfried , Patsch Janina , Metzelder Martin , Reck-Burneo Carlos A.
Published: July 2022

Introduction Anorectal malformations (ARM) affect 1 in 5,000 newborns with a wide range of defects. In the absence of a visible fistula, the diagnosis and classification of ARM require an augmented pressure distal colostogram. This procedure can be done after a diverting colostomy has been performed and implies exposing the child to radiation. We hypothesized that high-resolution transperineal ultrasound could correctly diagnose the type of ARM, thus sparing radiation exposure.

Case Description Four full-term male newborns with ARM and no visible anal opening were referred to our center for further management. A diverting descendostomy was performed in the first 48 hours of life in all cases. Prior to the reconstructive surgery, we performed a high-resolution transperineal ultrasound with 3D tomographic reconstruction of the perineal region to assess the urethra, the rectum, and a possible fistula. Findings were compared with a conventional augmented pressure distal colostogram. The image acquisition was fast and did not cause any additional distress to the children.

Conclusion In all cases the results of the distal colostogram nicely correlated with the high-resolution transperineal ultrasound with 3D tomographic reconstruction. In the future, we envision a time when it can potentially replace the distal colostogram in preoperative assessment of ARM with no distress and exposure to radiation.

Published: July 2022

Introduction Complementary and alternative medicine (CAM) is a growing branch of medicine that can improve the quality of life of many people. This study aimed to assess comparatively the knowledge, attitude, and use of CAM among graduation year pharmacy and medicine students at the University of Benghazi, Libya.

Method A cross-sectional survey was conducted among graduation year pharmacy and medicine students at the University of Benghazi for 4 months. The study tool was a self-administered online questionnaire and consisted of four main sections: demographic data, use, knowledge, and attitude toward CAM.

Results Most of the study respondents were females, and most were from Benghazi city. CAM use among pharmacy students was significantly higher (p-value= 0.001), with ruguia being the most commonly used modality (52.5%), followed by cupping-Al hijama and herbal medicine. Minor ailments and acute illnesses were the main medical conditions treated with CAM, and the unnecessary physician intervention was the top reason for practicing CAM among students. CAM knowledge and attitude were significantly higher among pharmacy students (p-value= 0.000 and 0.001, respectively).

Conclusion CAM was commonly practiced among the study participants. Their overall knowledge of CAM was limited, whereas their attitude toward it was positive, with pharmacy students having a better degree of both.

Published: July 2022

Purpose This retrospective study aimed to study the applicability of 2015 adult American Thyroid Association (ATA) differentiated thyroid cancer (DTC) postoperative risk stratification and guidelines in the pediatric population for evaluating the number of metastatic lymph nodes in the postoperative risk stratification and postradioactive iodine (RAI) treatment dynamic risk stratification (DRS) using response to treatment (RTT) reclassification. In addition, the effect of pubertal status and gender was assessed on disease presentation and prognosis.

Methods Data of 63 DTC patients aged 20 years or less, stratified into prepubertal, pubertal, and postpubertal age groups, was divided into low, intermediate, and high-risk groups using pediatric ATA recurrence risk stratification. Forty-seven patients were classified as responders (excellent and indeterminate responses) and incomplete responders (biochemical and structurally incomplete responses) by assessing the RTT at 1.5 years follow-up similar to recommendation of 2015 adult DTC ATA guidelines.

Results Female-to-male ratio showed a trend of gradual increase with increasing age. Significantly more responders were observed in low- and intermediate-risk groups than in high-risk group (p = 0.0013; p = 0.017, respectively), while prepubertal group had more extensive (N1b) disease. Using DRS at follow-up of 1.5 year, pubertal and postpubertal groups showed significantly better response to RAI. More female than male patients showed response and took significantly less time to respond to RAI (p = 0.003).

Conclusion RAI response in pediatric DTC depends on pubertal status, gender, and number of malignant nodes. DRS using RTT classification may be applicable early at 1.5 years after initial therapy in different pubertal age and risk groups.

Comparative analysis of hydration layer reorientation dynamics of antifreeze protein and protein cytochrome P450
Authors: Yu Hongfeng , Zhang Qiang , Zhuang Wei
Published: July 2022

Antifreeze proteins (AFPs) inhibit ice re-crystallization by a mechanism remaining largely elusive. Dynamics of AFPs’ hydration water and its involvement in the antifreeze activity have not been identified conclusively. We herein, by simulation and theory, examined the water reorientation dynamics in the first hydration layer of an AFP from the spruce budworm, Choristoneura fumiferana, compared with a protein cytochrome P450 (CYP). The increase of potential acceptor water molecules around donor water molecules leads to the acceleration of hydrogen bond exchange between water molecules. Therefore, the jump reorientation of water molecules around the AFP active region is accelerated. Due to the mutual coupling and excitation of hydrogen bond exchange, with the acceleration of hydrogen bond exchange, the rearrangement of the hydrogen bond network and the frame reorientation of water are accelerated. Therefore, the water reorientation dynamics of AFP is faster than that of CYP. The results of this study provide a new physical image of antifreeze protein and a new understanding of the antifreeze mechanism of antifreeze proteins.
Boron-containing thermally activated delayed blue fluorescence materials via donor tuning: A theoretical study
Authors: Ji Yan-Lin , Li Quan-Song
Published: July 2022

Based on the boron-containing thermally activated delayed fluorescence (TADF) compound p-AC (AC: acridine) 5,9-dioxa-13b-boranaphtho [3,2,1-de] anthracene (a), a series of new TADF molecules b1−b4 were designed via adding two nitrogen atoms at the AC donor part. Density functional theory and time-dependent density functional theory calculations were performed on the frontier orbital energy levels, emission spectra, singlet-triplet states energy gaps (ΔEST), reverse intersystem crossing (RISC) rate constant (kRISC) for compounds a and b1−b4. Our calculation results show that the maximum emission wavelengths of b1−b4 are significantly blue-shifted by 47−125 nm compared with that of a. Molecules b1 and b3 exhibit dark-blue emission, while molecules b2 and b4 display light-blue emission, indicating that these four derivatives could be potential organic light-emitting diode (OLED) candidates with blue-light emitting. Moreover, we found the RISC processes in a, b2, and b4 can occur not only from T1 state to S1 state, but also from T2 state to S1 state significantly, while the RISC processes in b1 and b3 mainly take place via the T2→S1 hot exciton way. Importantly, the T1→S1 kRISC values of b2 and b4 are predicted to be two to three times of that of a, indicating enhanced TADF property. Our results not only provide two promising boron-based TADF candidates (b2 and b4), but also offer useful theoretical basis for the design of blue OLED materials.

Published: July 2022

In this work, electron energy spectroscopic mapping of surface plasmon of Ag nanostructures on highly oriented pyrolytic graphite is reported. Benefitting from the angular dispersive feature of the present scanning probe electron energy spectrometer, a multi-channel detection mode is developed. By scanning along one direction, the two-dimensional intensity distribution of Ag surface plasmon excitation due to the collision of electron emitted from the tip can be obtained in parallel. The spectroscopic spatial resolution is determined to be around 80 nm.

Neuromorphic computing approaches become increasingly important as we address future needs for efficiently processing massive amounts of data. The unique attributes of quantum materials can help address these needs by enabling new energy-efficient device concepts that implement neuromorphic ideas at the hardware level. In particular, strong correlations give rise to highly non-linear responses, such as conductive phase transitions that can be harnessed for short- and long-term plasticity. Similarly, magnetization dynamics are strongly non-linear and can be utilized for data classification. This Perspective discusses select examples of these approaches and provides an outlook on the current opportunities and challenges for assembling quantum-material-based devices for neuromorphic functionalities into larger emergent complex network systems.
Mechanism study of flow characteristics on small HAWT blade surfaces based on airfoil concavity under yaw conditions
Authors: Ma Jianlong , Chen Yanan , Zhao Ming
Published: July 2022

Aiming to solve the power output reduction caused by the flow separation, this study applied a passive flow control method on blade suction surfaces of a small horizontal axis wind turbine. An airfoil with a semi-elliptical concavity was introduced, and several concave blades were, thus, designed. Among them, the blade with a concavity located at 80% chord and a length of 350 mm was selected for further analysis according to the aerodynamic performance. As a result, it has been found that the concave airfoil had better performance at high wind speeds, low rotational speeds, and small yaw angles, especially the positive yaw conditions. The flow field mechanism could be interpreted with a positive pressure gradient generated by the airfoil concavity. Under the positive yaw angle of 10°, the concavity effect resulted in a greater aerodynamic lift. The azimuth angle of 0° shows an obvious control effect at the blade tip. On the contrary, the concavity has little effect at an azimuth angle of 120° near the leading-edge. At the azimuth angle of 240°, a significant concavity effect at the blade root could be found, while the aerodynamic benefits were not as remarkable as an azimuth angle of 0° in the vicinity of the blade tip. Aside from that, when the flow separation was serious due to the three-dimensional rotational effect, the concavity has no distinct effect on separation control. In essence, the airfoil concavity had a favorable impact on flow separation control and effectively enhanced the power output of the wind turbine.

Published: July 2022

Diabetes prevalence is increasing; the technologies and medicines used to manage diabetes have become more complex, and the specialist health workforce with qualifications in diabetes is insufficient. Generalist health professionals have limited diabetes knowledge, despite engaging with people with diabetes in healthcare daily. An innovative framework is needed to align with the Australian National Diabetes Strategy to build a competent, flexible and adaptive workforce to promote excellence in diabetes care. A three-staged modified Delphi technique was used to identify a consensus Capability Framework for Diabetes Care (the ‘Framework’). An implementation phase followed, involving representation from people with diabetes and key health professional organisations to co-design and implement the ‘Framework’. The ‘Framework’ can guide curricula at universities and TAFE institutes, and the professional development and practice of Australian nurses, allied health professionals, First Nations Australians health workers and practitioners, pharmacists, midwives and health assistants when delivering care to people living with diabetes. The ‘Framework’ defines nine core capabilities that healthcare providers require to deliver diabetes care effectively, underpinned by three sets of attributes for seven practice levels to enable the workforce. Information within the practice levels provides a nationally consistent approach to learning and training different healthcare providers in the essential elements of diabetes care. A ‘living’ evidence-based national ‘Framework’ for the whole health workforce and associated online resources will help promote a more responsive health workforce delivering better and more equitable diabetes care.

Published: July 2022

Introduction Recently immigrated Pakistani women need knowledge about their new country’s healthcare system to better access appropriate care. Aim This study explores the knowledge of Pakistani immigrant women about New Zealand’s healthcare system. Methods An online questionnaire was developed and administered using Qualtrics© software. Closed and open-ended questions were asked about knowledge and challenges when entering a new healthcare system. The target population was Pakistani women aged ≥18 years, living in New Zealand for <5 years. Participants were recruited from different cities, primarily through snowball sampling using various social media. The survey was conducted in English, and responses were analysed using Microsoft Excel. Results Two hundred respondents (covering 881 family members) answered most questions. The average age of the participants was 26–34 years, and most were housewives. Recently immigrated Pakistani women considered it difficult to access information about medical centres, GP registration, subsidised medicines, maternity services, emergency/after-hours services, and mental health for children and adults. Most participants stated that they obtained information about the healthcare system from friends and searched Google. Discussion Recently immigrated Pakistani women face challenges finding information about New Zealand’s healthcare system, which may impact access to health care for themselves and their families. Information is particularly needed before or soon after arrival in New Zealand.

Published: July 2022

Background General practitioners (GPs) play a central role during the COVID-19 pandemic, and yet awareness of their mental health is limited. Methods A nationwide online survey of self-identified frontline healthcare workers was conducted between 27 August and 23 October 2020. Participants were recruited through health and professional organisations, colleges, universities, government contacts, and media. A subset of the findings on GPs and hospital medical staff (HMS) was used for this study. Results Of 9518 responses, there were 389 (4%) GPs and 1966 (21%) HMS. Compared with HMS, GPs received significantly less training on personal protective equipment usage or care for COVID-19 patients, and less support or communication within their workplace. GPs were significantly more concerned about household income, disease transmission to family and being blamed by colleagues if they became infected, all of which were associated with worse psychological outcomes. Significantly more GPs reported burnout, and experienced moderate-to-severe emotional exhaustion than HMS. Both groups used similar coping strategies, except fewer GPs than HMS used digital health applications or increased alcohol consumption. Less than 25% of either group sought professional help. Conclusions GPs are vital in our healthcare systems, yet face unique workplace challenges and mental health stressors during the pandemic. Targeted workplace and psychological support is essential to protect wellbeing among the primary care workforce.

Transporters belonging to the Resistance-Nodulation-cell Division (RND) superfamily of proteins such as
Mycobacterium tuberculosis
MmpL3 and its analogs are the focus of intense investigations due to their importance in the physiology of
Corynebacterium–Mycobacterium–Nocardia
species and antimycobacterial drug discovery. These transporters deliver trehalose monomycolates, the precursors of major lipids of the outer membrane, to the periplasm by a proton motive force–dependent mechanism. In this study, we successfully purified, from native membranes, the full-length and the C-terminal truncated
M. tuberculosis
MmpL3 and
Corynebacterium glutamicum
CmpL1 proteins and reconstituted them into proteoliposomes. We also generated a series of substrate mimics and inhibitors specific to these transporters, analyzed their activities in the reconstituted proteoliposomes, and carried out molecular dynamics simulations of the model MmpL3 transporter at different pH. We found that all reconstituted proteins facilitate proton translocation across a phospholipid bilayer, but MmpL3 and CmpL1 differ dramatically in their responses to pH and interactions with substrate mimics and indole-2-carboxamide inhibitors. Our results further suggest that some inhibitors abolish the transport activity of MmpL3 and CmpL1 by inhibition of proton translocation.
Rethinking pronunciation posttesting
Authors: Nagle Charles
Published: July 2022

Pronunciation training studies shed light on the training paradigms and features that are most likely to promote learning and lead to optimal instructional outcomes. Yet, delayed posttesting is surprisingly rare in experimental work. As such, although several research syntheses have shown that pronunciation instruction is effective for promoting short-term gains, the long-term impact of instruction remains largely unknown. In this editorial, I address the need for delayed measures in experimental pronunciation research and make the case for rethinking the number, timing, and scope of such measures.
Because We’re Worth It
Authors: Lambert Joseph , Walker Callum
Published: July 2022

Rate-setting is a problematic area for newcomers to translation and established practitioners alike. Survey data generally support the view that translators feel underpaid and that money matters remain a chief ethical and pragmatic concern, but appropriate guidance is almost entirely absent from introductory textbooks on the translation profession and documentation prepared by industry associations remains unsatisfactory. Focusing on the translation industry in the United Kingdom, this conceptual paper explores constraints that limit price formation practices, and argues that translators feel under threat from disruptive technologies, Uberisation, and non-professional translation, now more than ever. We explore the complex interaction between status, internal and external perceptions, and regulation, and illustrate their push-pull relationship with rate-setting within a range of industry ‘educators’, uncovering the ways in which translators themselves, translation associations, and academic institutions directly and indirectly impact upon rate-setting practices. The article concludes by considering potential channels to buoy status and improve rate-setting practices in the translation industry.

Published: July 2022

In this paper, we analyse the global structure of the Bronnikov wormhole, which is the most general spherically-symmetric and static solution in Einstein gravity coupled to a free massless phantom scalar. We then introduce a scalar potential and construct a large class of exact solutions that can be viewed as generalizations of the Bronnikov wormhole. We study the global structure and classify the parameters of these new wormholes. For suitable parameters, some are regular black holes with a bouncing de Sitter spacetime inside the event horizon.
A constitutive model and its numerical implementation for reversible behavior of shape memory hydrogels
Authors: Hu Yunqiang , Jia Fei , Fu Zijian , Liu Yanju , Leng Jinsong
Published: July 2022

Shape memory hydrogels (SMHs) are kinds of smart materials with great importance in many fields, such as drug release and soft robotics. In order to design the structures base on SMHs, it is necessary to reveal the mechanism of the shape memory effect and establish the constitutive model of SMHs. However, the existing constitutive models can not describe some of important mechanical behavior of SMHs, such as reversible shape memory effects. In this paper, a three-dimensional finite deformation constitutive model is developed for SMHs with reversible shape memory effects caused by the conformation transition of N-isopropylacrylamide (PNIPAM). In order to well capture its reversible shape memory effect, the polymer network for PNIPAM is decomposed into two parts, coil PNIPAM and globule PNIPAM, with different reference configurations. Then this model is implemented into a user material subroutine (UMAT) and is used for simulating the equilibrium swelling, isothermal uniaxial tension, reversible shape memory behavior and multiple shape memory cycles of SMHs. Our model is validated by comparing the simulation results with experiments. The deformation of a more complex 3D structure and a bilayer structure containing SMHs are also numerically studied which demonstrates great potential of our model in exploring the application of SMHs.
Evolutionary Game Study on the Supervision Strategy in the Operation Phase of Green Public Buildings Based on System Dynamics Simulation
Authors: Qin Zhongfu , Wang Jian , Ji Chenyi
Published: July 2022

In the energy performance contracting (EPC) mode, an effective way to achieve green public buildings, the information asymmetry among stakeholders in the operation phase is critically adverse to the energy-saving effect of green public buildings. This paper constructs an evolutionary game model between energy users and energy-saving companies (ESCOs) in the operation phase of green public buildings under the premise of limited rationality. Vensim PLE software is used to build the corresponding simulation model to simulate the strategy evolution of players under different initial strategies. Typical scenarios with different government punishment, penalties from energy users, and opportunistic gains of ESCOs, respectively, are set up to conduct sensitivity analysis. The results show that dynamic alternation exists in the strategy evolution of players during the operation phase of green public buildings under the EPC mode, and it is influenced by the simulation period and players’ initial strategies. And the evolution in different typical scenarios is influenced by the aforementioned parameters with different significance. This study can provide a basis for the supervision strategy of ESCOs in the operation phase of green public buildings by local governments and energy users thus promoting the energy-saving operation of green public buildings for final carbon reduction.

Authors: Chen Linfeng , Wang Yi , Hu Rui , Xu Gang , Ma Shuang
Published: July 2022

Aiming at the problem that the renewable energy cannot be efficiently utilized and the energy consumption cost is high in the production process of the park with wind and solar energy, an integrated energy system (IES) for the park that takes into account the wind and solar energy consumption is proposed. Optimize the scheduling method. First, an output model of the park’s comprehensive energy system including wind-solar renewable energy was established, and biogas was used as the gas source. Then, considering a variety of energy constraints, and taking the lowest energy consumption cost and the highest wind and light absorption rate as the goal, the improved multi-objective particle swarm algorithm is used to optimize the solution. Finally, the proposed method is verified by taking an integrated energy system of a park as a practical example. The results show that the proposed optimal scheduling method can effectively reduce the daily operating cost of the park and improve the local consumption rate of renewable energy.

Published: July 2022

Rolled strip pulse forming line (RSPFL) with combined insulation structure can effectively increase the breakdown electric strength and energy storage density of pulse forming line by optimization of the edge field enhancement effect. In this paper, a combined insulation (which consists of polyimide and polyvinylidene fluoride films) based RSPFL is investigated theoretically and numerically. Firstly, parameters of the pulse forming line was designed theoretically. Secondly, the finite element software was employed to study the influence of insulation film combination and structural parameters on the electric field distribution and the transmission characteristics. The parameters are then optimized. Finally, combined insulation based RSPFL was successfully used as a single pulse forming line, and a 200 ns quasi-square pulse was obtained on a 2.5 Ω dummy load by simulation. The simulation shows that it has an energy storage density of approximately 19.57 J/L when the PFL is charged to 60 kV.

Authors: Wang Rui , Shi Fangyu
Published: July 2022

The modern large civil aircraft has the trend to utilize the remote distribution network. This paper presents an optimization concept for this distribution network to optimize remote power distribution unit placement in aircraft to decrease the wire weight. A model formulation has been created to minimize the total wire weight. The length of wire was calculated approximately by the different longitinal axis of center of gravity of wire ends. To solve the wiring weight reduction problem, the loads are selected to connect to specific remote power distribution unit which position is close, then model formulation has been transformed to the linear programming algorithm. In order to validate the concept a simulation model and different calculation case have been built. The calculation results show the method can decrease wires weight in remote power distribution system and has shown high benefits.
Performance Analysis of DC-DC converters for Solar PV fed Switched Reluctance motor for Electric Vehicle Applications
Authors: Mahalakshmi G , Kanthalakshmi S , Maharaja K
Published: July 2022

This paper describes the performance of a Solar PV-powered switched reluctance motor with low torque ripple in electric vehicle applications. The prominence of switched reluctance motors has become significant in the electric vehicle industry, because of its ineradicable characteristics like simple structure, absence of rotor windings, less maintenance and its self-starting capability. However, the limitation of SRM is its high torque ripple because of its nonlinear characteristics. The performance of a switched reluctance motor with various DC –DC converters is analysed in this work and the results are compared in terms of the speed of the motor and its torque ripple percentage. The switching time of the converter is controlled by the MPPT controller, which uses incremental conductance and the Integrator method. The converters presented in this work are the Boost converter and the Cuk converter. These two types of converters are designed in MATLAB software and their characteristics are analysed while supplying the switched reluctance motor. The suitability of the proposed system with the motor is analysed by simulation results. From the results, it is confirmed that the performance of the Solar PV fed Switched reluctance motor is improved in terms of speed and torque ripple by implementing this type of converter. Hence, it is suitable for electric vehicle applications, which require less torque ripple and mechanical vibrations.
Dust Cruster Application at Vale Oman Stockyard Area
Authors: Hussein Samer
Published: July 2022

The main objective of this paper is to share Vale Oman knowledge and experiences in dust control of bulky material handling in stockyard areas, where the piles of iron ore stocked for a certain period before use in the plant. Those piles are subjected to high wind speed which leads to generate dust emission. The new dust suppressant had been tested and evaluated through a Defused Dust Emission Monitoring Network (DDEMN), The dust suppressant solution sprayed on the stockpiles by using Vale stacker and reclaimer equipment forming a white-coloured crust that eliminate the wind effect on the iron ore piles and give clear visual indication for the inspectors or operators that the pile is fully covered. The results of Emission Rate from yard area after applying new dust cruster decreased around 75 % which preserve the environment and gain sustainable operation. This application of dust control can be compared with any other method used based on pros and cons and efficacy.

Published: July 2022

Computer Vision (CV) based object detection system is used for locating and recognizing objects of interest in the digital images or videos/live streams. In this work, real-time face mask detection and verification of vaccination certificates are implemented using a Jetson Xavier kit. Initially, live stream video is captured through a Universal Serial Bus (USB) High Definition (HD) video camera. Then, pre-processed using the standard Python CV library to grab a frame for further processing. Using Haar-Cascade Classifier and face encoding, recognition of the face from the frame is performed and labeled appropriately, then a pre-trained Deep Learning (DL) model is used to locate the target class (mask) on the frame. The Quick Response (QR) code embedded in the vaccination certificate is also analyzed from the frame. The beneficiary and vaccination details are obtained from the website of the concerned authority. Finally, the unique QR code with the relevant information is stored in the Jetson Xavier kit for detection and retrieval during the next instance. The system’s performance is verified and found to be good in terms of accuracy compared to other methods considered in this work. The implementation of this work will cater to the local community and help achieve the nation’s sustainable development goal.

Published: July 2022

Additive manufacturing enables the production of high performance radio frequency device components, but most printable materials are plagued by large losses that render them impractical for robust performance applications beyond rapid prototyping. Here, we demonstrate a set of fully three-dimensional (3D) printed band-stop filters fabricated by printing reactive silver ink onto three different additively manufactured resin substrates with varying dielectric properties. Each of the dielectric substrates were fabricated using stereolithography or digital light processing printing methods. By switching from a dielectric with tanδ = 0.06 to one with tanδ = 0.0073, we can decrease the total loss present in the structure by up to 2 dB. As enabled by 3D additive manufacturing, we also show that regardless of the dielectric material, moving from two-dimensional planar patterns to fully-3D topographies allows us to simultaneously widen the filter stopband by 2 GHz and theoretically increase signal rejection by up to 30 dB. This demonstration of a fully additively-manufactured, 3D band-stop filter that closely matches simulations represents a new class of device construction that was previously inaccessible using only 2- and 2.5-D manufacturing techniques.

endowed with a universal K-matrix, i.e., a universal solution of a generalized reflection equation, yielding an action of cylindrical braid groups on tensor products of its representations. We prove that new examples of such universal K-matrices arise from quantum symmetric pairs of Kac-Moody type and depend upon the choice of a pair of generalized Satake diagrams. In finite type, this yields a refinement of a result obtained by Balagović and Kolb, producing a family of non-equivalent solutions interpolating between the quasi-K-matrix originally due to Bao and Wang and the full universal K-matrix. Finally, we prove that this construction yields formal solutions of the generalized reflection equation with a spectral parameter in the case of finite-dimensional representations over the quantum affine algebra

A comprehensive protein design protocol to identify resistance mutations and signatures of adaptation in pathogens
Authors: Padhi Aditya K , Tripathi Timir
Published: July 2022

Most pathogens mutate and evolve over time to escape immune and drug pressure. To achieve this, they alter specific hotspot residues in their intracellular proteins to render the targeted drug(s) ineffective and develop resistance. Such hotspot residues may be located as a cluster or uniformly as a signature of adaptation in a protein. Identifying the hotspots and signatures is extremely important to comprehensively understand the disease pathogenesis and rapidly develop next-generation therapeutics. As experimental methods are time-consuming and often cumbersome, there is a need to develop efficient computational protocols and adequately utilize them. To address this issue, we present a unique computational protein design protocol that identifies hotspot residues, resistance mutations and signatures of adaptation in a pathogen’s protein against a bound drug. Using the protocol, the binding affinity between the designed mutants and drug is computed quickly, which offers predictions for comparison with biophysical experiments. The applicability and accuracy of the protocol are shown using case studies of a few protein–drug complexes. As a validation, resistance mutations in severe acute respiratory syndrome coronavirus 2 main protease (Mpro) against narlaprevir (an inhibitor of hepatitis C NS3/4A serine protease) are identified. Notably, a detailed methodology and description of the working principles of the protocol are presented. In conclusion, our protocol will assist in providing a first-hand explanation of adaptation, hotspot-residue variations and surveillance of evolving resistance mutations in a pathogenic protein.
Peer Support Workers as Equal Team Members. A Case Study of Peer Support in Glasgow Housing First
Authors: Černá Eliška , Gojová Alice
Published: July 2022

The text investigates peer support in the Glasgow Housing First project. Housing First is considered a social innovation towards ending chronic homelessness. Peer support should be an integral part of this approach, but little is known about its role. The aim of this text is to analyse peer support in the project from the perspective of its team and service users. We carried out an instrumental case study. For data collection we used semi-structured and group interview, direct observation, and studied service users’ files. To analyse the data, we conducted thematic analysis. We found out that peer support workers are seen as equal team members. Peer support needs to be recognised in the organisation, job role defined, and an adequate salary secured. We also present challenges in the areas of personal boundaries, self-care, and fulfilment of formal job requirements, and therefore it is crucial to provide peer mentor’s position within the team. Peer support relates to the provision of healing relationship with hard engagers and service users’ led support. Together with using specific tools and community resources, peer support results in either graduation from Housing First, sustaining their tenancy as Housing First tenants, or less days in homelessness.

Aims

To evaluate the ability of Systematic COronary Risk Estimation 2 (SCORE2) and other pre-screening methods to identify individuals with high coronary artery calcium score (CACS) in the general population.

Methods and results

Computed tomography-based CACS quantification was performed in 6530 individuals aged 45 years or older from the general population. Various pre-screening methods to guide referral for CACS were evaluated. Miss rates for high CACS (CACS ≥300 and ≥100) were evaluated for various pre-screening methods: moderate (≥5%) and high (≥10%) SCORE2 risk, any traditional coronary artery disease (CAD) risk factor, any Risk Or Benefit IN Screening for CArdiovascular Disease (ROBINSCA) risk factor, and moderately (>3 mg/24 h) increased urine albumin excretion (UAE). Out of 6530 participants, 643 (9.8%) had CACS ≥300 and 1236 (18.9%) had CACS ≥100. For CACS ≥300 and CACS ≥100, miss rate was 32 and 41% for pre-screening by moderate (≥5%) SCORE2 risk and 81 and 87% for high (≥10%) SCORE2 risk, respectively. For CACS ≥300 and CACS ≥100, miss rate was 8 and 11% for pre-screening by at least one CAD risk factor, 24 and 25% for at least one ROBINSCA risk factor, and 67 and 67% for moderately increased UAE, respectively.

Conclusion

Many individuals with high CACS in the general population are left unidentified when only performing CACS in case of at least moderate (≥5%) SCORE2, which closely resembles current clinical practice. Less stringent pre-screening by presence of at least one CAD risk factor to guide CACS identifies more individuals with high CACS and could improve CAD prevention.
Monstruosité de l’héroïne: réécriture de
Médée

Chanson douce

Leïla Slimani’s
Chanson douce
draws an explicit parallel between its protagonist, Louise, a nanny who eventually kills the children she looks after, and the mythological figure of Medea, specifically Pierre Corneille’s version of the Princess of Colchis. This article argues that the analogy between Louise and Medea, rather than restricting Louise to being exclusively monstrous because of the infanticide, highlights the paradoxical dimension of her character. Her monstrosity, in fact, is inseparable from her heroism. We will call upon Aristotle’s principles of tragedy as well as Corneille’s own theoretical writings — in which the playwright himself explains that his Médée, while a criminal, remains admirable — to show how Louise is able to portray herself as a simultaneously laudable and blameable character by affirming her allegiance to a classical ideal of dignity. The dramaturgical approach of the article shines a new light on the protagonist of this controversial novel, winner of the 2016 Prix Goncourt.

Background

Booklice (psocids) in the genus Liposcelis (Psocoptera: Liposcelididae) are a group of important storage pests, found in libraries, grain storages, and food-processing facilities. Booklice are able to survive under heat treatment and typically possess high resistance to common fumigant insecticides, hence posing a threat to storage security worldwide.

Results

We assembled the genome of the booklouse, L. brunnea, the first genome reported in Psocoptera, using PacBio long-read sequencing, Illumina sequencing, and chromatin conformation capture (Hi-C) methods. After assembly, polishing, haplotype purging, and Hi-C scaffolding, we obtained 9 linkage groups (174.1 Mb in total) ranging from 12.1 Mb to 27.6 Mb (N50: 19.7 Mb), with the BUSCO completeness at 98.9%. In total, 15,543 genes were predicted by the Maker pipeline. Gene family analyses indicated the sensing-related gene families (OBP and OR) and the resistance-related gene families (ABC, EST, GST, UGT, and P450) expanded significantly in L. brunnea compared with those of their closest relatives (2 parasitic lice). Based on transcriptomic analysis, we found that the CYP4 subfamily from the P450 gene family functioned during phosphine fumigation; HSP genes, particularly those from the HSP70 subfamily, were upregulated significantly under high temperatures.

Conclusions

We present a chromosome-level genome assembly of L. brunnea, the first genome reported for the order Psocoptera. Our analyses provide new insights into the gene family evolution of the louse clade and the transcriptomic responses of booklice to environmental stresses.

Intussusception is a rare condition in adults and presents a diagnostic challenge. Clinical presentation tends to be chronic and non-specific. Unlike the pediatric population, most adult intussusceptions have structural lesions as lead points. Here, we present a case of jejunojejunal intussusception in a 27-year female due to adenoma of small bowel.
