Simultaneous network reconfiguration and DG allocation in radial distribution networks using arithmetic optimization algorithm
Authors: Dey Indrajit , Roy Provas Kumar 
Published: March 2023

AbstractThis article introduces a newly suggested meta‐heuristic arithmetic optimization algorithm (AOA) to reorganize the distribution network with the simultaneous distribution of distributed generators (DGs). The algorithm is designed to be flexible with a new approach that employs the scattering behavior of arithmetic operators in mathematics to discover the solution space more proficiently throughout the path of iterations. The usefulness of the AOA is demonstrated on 33‐bus, and 69‐bus radial distribution networks (RDNs) with network reconfiguration (NR) in the presence of DGs. The main objective of NR and effective DG arrangement in RDNs is to truncate the true power loss, reduce the voltage fluctuation, and voltage stability index enlargement. In order to increase the efficacy of the RDN, a multi‐objective function is created in view of active power loss, voltage deviation, and voltage stability index of the system with appropriate strategy without destroying the system restrictions. To illustrate the effectiveness of the RDN, four separate cases of NR and DG employment have been carried out. Four cases namely, base case (case‐1), reconfiguration (case‐2), simultaneous reconfiguration and DG installation with a unity power factor (case‐3), and simultaneous reconfiguration and DG installation with 0.95 lagging power factor (case‐4) are explored. The projected technique gives better results than other renowned methods, namely, fireworks algorithm (FWA), harmony search algorithm (HSA), refined genetic algorithm (RGA), and improved sine‐cosine algorithm (ISCA) strategy in view of 33, 69‐bus RDN at three dissimilar load conditions and its supremacy is confirmed.
The Interplay between Individuals and Teams in Producing Original Work
Authors: Bellard Erwan , Delobbe Nathalie 
Published: March 2023

ABSTRACTThis study investigates the assumption that teams are the basic unit for creativity and innovation in organizations. Through a quasi‐experiment conducted with 548 professionals participating in a training course on management, the study first examines whether individuals opt for intrinsically more creative solutions than groups in a music composition task. Secondly, it explores whether alternating between group and individual music composition has an impact on the originality of the pieces composed. The results show that individuals make more original choices than groups whatever protocol is used, confirming that individuals are better able to think outside of the box, take risks, and demonstrate the divergent thinking necessary for creativity. Moreover, individuals choose less original options when their independent work is preceded by a group composition exercise. Paradoxically, we observe that in all cases, participants are more satisfied with their group production than their individual production. We conclude with some recommendations for developing the most original and satisfactory collective solutions to complex problems.

AbstractLow interfacial tension (IFT) drainage and imbibition are effective methods for improving oil recovery from reservoirs that have low levels of oil or are tight (i.e., exhibit low oil permeability). It is critical to prepare a high efficient imbibition formula. In this work, a novel 2,4,6‐tris(1‐phenylethyl)phenoxy polyoxyethylene ether hydroxypropyl sodium sulfonate (TPHS) surfactant was synthesized and evaluated for imbibition. Its structure was confirmed by Fourier transform infrared spectroscopy and the interfacial tension (IFT) of the crude oil/0.07% TPHS solution was 0.276 mN/m. When 0.1 wt% TPHS was mixed with 0.2 wt% alpha olefin sulfonate (AOS), the IFT was lowered to 6 × 10−2 mN/m. The synergy between nanoparticles (NPs) and TPHS/AOS mixed surfactant was studied by IFT, contact angle on sandstone substrates, zeta potential, and spreading dynamics through microscopic methods. The results show that the surfactant likely adsorbs to the NP surface and that NP addition can help the surfactant desorb crude oil from the glass surface. With the addition of 0.05 wt% SiO2 NPs (SNPs), the imbibition oil recovery rate increased dramatically from 0.32%/h to 0.87%/h. The spontaneous imbibition recovery increased by 4.47% for original oil in place (OOIP). Compared to flooding by TPHS/AOS surfactant solutions, the oil recovery of forced imbibition in the sand‐pack increased by 12.7% OOIP, and the water breakthrough time was delayed by 0.13 pore volumes (PV) when 0.05% SNPs were added. This paper paves the way for enhanced oil recovery in low‐permeability sandstone reservoirs using novel TPHS/AOS surfactants and SNPs.

Published: March 2023

AbstractBackground and ObjectivesFew studies have investigated the effects of time to treatment initiation (TTI) for soft tissue sarcomas (STS). Our objective was to investigate the risk factors for prolonged TTI and the effects of prolonged TTI on local recurrence free survival (LRFS), distant metastasis free survival (DMFS), and disease specific survival (DSS).MethodPatients diagnosed with high‐grade STS of the extremities and trunk from 2011 to 2020 were included. TTI was grouped into two groups (treatment provided in less than vs. more than or equal to 30 days). Two‐year and 5‐year survival probabilities were calculated for LRFS, DMFS, and DSS. Cox regression and Kruskal–Wallis tests in univariate analysis were conducted to find risk factors affecting TTI and the survival outcomes.ResultsIn the univariate analysis, diagnosis in the later 5‐year period of the study, tumor size, and treatment modality were associated with prolonged TTI. TTI ≥30 days was associated with higher DMFS but no association was found with LRFS or DSS. Tumor size, surgical margins, and provision of surgery were associated with DSS.ConclusionDespite the delay in treatment for STS patients caused by the COVID‐19 pandemic, our study showed TTI of more than 30 days does not negatively impact patients.

Published: March 2023

AbstractAchieving directional control of optical antennas is critically important for the design of flexible interconnects between free‐space optics and on‐chip photonic circuitry. Here, a new concept of tunable transverse scattering of light from dielectric nanodimer antennas is suggested theoretically and demonstrated experimentally based on a selective excitation of the specific electromagnetic multipoles with the simultaneous suppression of both forward and backward scatterings. Importantly, it is revealed that the direction of the transverse scattering from nanodimers can be steered actively by varying the vectorial properties of the generalized cylindrical beams, and this new functionality in the experiment is demonstrated.

Globally hypoelliptic triangularizable systems of periodic pseudo‐differential operators
Authors: de Ávila Silva Fernando 
Published: March 2023

AbstractThis paper presents an investigation on the global hypoellipticity problem for a class of systems of pseudo‐differential operators on the torus. The approach consists in establishing conditions on the matrix symbol of the system such that it can be transformed into a suitable triangular form involving a nilpotent upper triangular matrix. Hence, the global hypoellipticity is studied by analyzing the behavior of the eigenvalues and their averages.

AbstractBackgroundThe International Parkinson and Movement Disorders Society (MDS) set up a working group on pediatric movement disorders (MDS Task Force on Pediatrics) to generate recommendations to guide the transition process from pediatrics to adult health care systems in patients with childhood‐onset movement disorders.MethodsTo develop recommendations for transitional care for childhood onset movement disorders, we used a formal consensus development process, using a multi‐round, web‐based Delphi survey. The Delphi survey was based on the results of the scoping review of the literature and the results of a survey of MDS members on transition practices. Through iterative discussions, we generated the recommendations included in the survey. The MDS Task Force on Pediatrics were the voting members for the Delphi survey. The task force members comprise 23 child and adult neurologists with expertise in the field of movement disorders and from all regions of the world.ResultsFifteen recommendations divided across four different areas were made pertaining to: (1) team composition and structure, (2) planning and readiness, (3) goals of care, and (4) administration and research. All recommendations achieved consensus with a median score of 7 or greater.ConclusionRecommendations on providing transitional care for patients with childhood onset movement disorders are provided. Nevertheless several challenges remain in the implementation of these recommendations, related to health infrastructure and the distribution of health resources, and the availability of knowledgeable and interested practitioners. Research on the influence of transitional care programs on outcomes in childhood onset movement disorders is much needed.
A radiofrequency coil for infants and toddlers

Published: March 2023

AbstractInfants and toddlers are a challenging population upon which to perform magnetic resonance imaging (MRI) of the brain, both in research and clinical settings. Because of the large range in head size during the early years of development, paediatric neuro‐MRI requires a radiofrequency (RF) coil, or set of coils, that is tailored to head size to provide the highest image quality. Mitigating techniques must also be employed to reduce and correct for subject motion. This manuscript describes an RF coil with a tailored mechanical–electrical design that can adapt to the head size of 3‐month‐old infants to 3‐year‐old toddlers. The RF coil was designed with tight‐fitting coil elements to improve the signal‐to‐noise ratio (SNR) in comparison with commercially available adult head coils, while simultaneously aiding in immobilization. The coil was designed without visual obstruction to facilitate an unimpeded view of the child's face and the potential application of camera or motion‐tracking systems. Despite the lack of elements over the face, the paediatric coil produced higher SNR over most of the brain compared with adult coils, including more than twofold in the periphery. Acceleration rates of fourfold in each Cartesian direction could be achieved. High SNR allowed for short acquisition times through accelerated imaging protocols and reduced the probability of motion during a scan. Modification of the acquisition protocol, with immobilization of the head through the adjustable coil geometry, and subsequently being combined with a motion‐tracking system, provides a compelling platform for scanning paediatric populations without sedation and with improved image quality.

AbstractAimMedical male circumcision (MMC) standards are critical in promoting clients’ safety and quality care. The aim is to report on factors that influence non‐compliance with standards for MMC in the Lesotho context.DesignA qualitative, explorative, descriptive research design was used.MethodFour focus group interviews were held with 19 purposively selected registered nurses providing routine MMC for one year or more.ResultsThree themes emerged namely: knowledge of quality standards, barriers to compliance, and perceived enabling working environment. Findings highlight barriers such as infrastructure, the high targets that are set for programmes, and societal and cultural issues. Fatigue and burnout were prevalent among MMC providers due to workload. These providers stated carelessness in their work was brought on by overconfidence in their skills, leading to poor compliance with quality standards.Public contributionImplementing public health interventions in a clinical setting requires careful planning to respond to epidemics.
Impact of fiber‐type and autoclave‐treatment at different temperatures on the mechanical properties and interface performance of various fiber‐reinforced 3D‐printed composites

Published: March 2023

AbstractThis paper investigates the impact of fiber type printed into various composites and autoclave treatment at different temperatures on the mechanical properties of aramid, glass, and carbon fiber reinforced additively manufactured composites. In addition, microstructure and interface performance concerning fiber type and autoclave treatment at different temperatures were also investigated. Fiber type results specified that carbon fiber reinforced composite offered higher tensile strength and Young's modulus of 231.84 MPa and 9.94 GPa as compared to glass, aramid and chopped fiber reinforced composites owing to the presence of stronger interface bonds. Autoclave treatment outcomes at 180°C indicated that carbon fiber reinforced composite exhibited the highest tensile strength and Young's modulus of 287.48 MPa and 12.53 GPa compared to glass, aramid and non‐autoclave composites due to denser structure accomplishment with minimal porosity. Micrographs regarding fiber type revealed that carbon fiber reinforced composites formed good interface bonding compared to glass, aramid and chopped fiber reinforced composites owing to rarer voids. Micrographs of autoclave treatment confirmed that cavities were removed due to improved wettability of matrix to fiber bundles at 180°C and strongest interface bonds were formed. Results demonstrated that autoclave treatment notably achieved optimum mechanical properties with improved strength and higher performance.
Management of noncytotoxic extravasation injuries: A focused update on medications, treatment strategies, and peripheral administration of vasopressors and hypertonic saline

Published: March 2023

AbstractExtravasation is the leakage of intravenous solutions into surrounding tissues, which can be influenced by drug properties, infusion techniques, and patient‐related risk factors. Although peripheral administration of vesicants may increase the risk of extravasation injuries, the time and resources required for central venous catheter placement may delay administration of time‐sensitive therapies. Recent literature gathered from the growing use of peripheral vasopressors and hypertonic sodium suggests low risk of harm for initiating these emergent therapies peripherally, which may prevent delays and improve patient outcomes. Physiochemical causes of tissue injury include vasoconstriction, pH‐mediated, osmolar‐mediated, and cytotoxic mechanisms of extravasation injuries. Acidic agents, such as promethazine, amiodarone, and vancomycin, may cause edema, sloughing, and necrosis secondary to cellular desiccation. Alternatively, basic agents, such as phenytoin and acyclovir, may be more caustic due to deeper tissue penetration of the dissociated hydroxide ions. Osmotically active agents cause cellular damage as a result of osmotic shifts across cellular membranes in addition to agent‐specific toxicities, such as calcium‐induced vasoconstriction and calcifications or arginine‐induced leakage of potassium causing apoptosis. A new category has been proposed to identify absorption‐refractory mechanisms of injury in which agents such as propofol and lipids may persist in the extravasated space and cause necrosis or compartment syndrome. Pharmacological antidotes may be useful in select extravasations but requires prompt recognition and frequently complex administration strategies. Historically, intradermal phentolamine has been the preferred agent for vasopressor extravasations, but frequent supply shortages have led to the emergence of terbutaline, a β2‐agonist, as an acceptable alternative treatment option. For hyperosmolar and pH‐related mechanisms of injuries, hyaluronidase is most commonly used to facilitate absorption and dispersion of injected agents. However, extravasation management is largely supportive and requires a protocolized multidisciplinary approach for early detection, treatment, and timely surgical referral when required to minimize adverse events.

Published: March 2023

AbstractRNA‐binding proteins (RBPs) play significant roles in many biological life activities, many algorithms and tools are proposed to predict RBPs for researching biological mechanisms of RNA‐protein binding sites. Deep learning algorithms based on traditional machine learning get better result for predicting RBPs. Recently, deep learning method fused with attention mechanism has attracted huge attention in many fields and gets competitive result. Thus, attention mechanism module may also improve model performance for predicting RNA‐protein binding sites. In this study, we propose convolutional residual multi‐head self‐attention network (CRMSNet) that combines convolutional neural network (CNN), ResNet, and multi‐head self‐attention blocks to find RBPs for RNA sequence. First, CRMSNet incorporates convolutional neural networks, recurrent neural networks, and multi‐head self‐attention block. Second, CRMSNet can draw binding motif pictures from the convolutional layer parameters. Third, attention mechanism module combines the local and global RNA sequence information for capturing long sequence feature. CRMSNet gets competitive AUC (area under the receiver operating characteristic [ROC] curve) result in a large‐scale dataset RBP‐24. And CRMSNet experiment result is also compared with other state‐of‐the‐art methods. The source code of our proposed CRMSNet method can be found in https://github.com/biomg/CRMSNet.

Published: March 2023

AbstractBackgroundThe fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), is a global pest that feeds on >350 plant species and severely limits production of cultivated grasses, vegetable crops and cotton. An efficient way to detect new invasions at early stages, and monitor and quantify the status of established infestations of this pest is to deploy traps baited with species‐specific synthetic sex pheromone lures.ResultsWe re‐examined the compounds in the sex pheromone glands of FAW females by gas chromatography‐electroantennogram detector (GC‐EAD), GC–mass spectrometry (MS), behavioral and field assays. A new bioactive compound from pheromone gland extracts was detected in low amounts (3.0% relative to (Z)‐9‐tetradecenyl acetate (Z9‐14:OAc), the main pheromone component), and identified as nonanal. This aldehyde significantly increased attraction of male moths to a mix of Z9‐14:OAc and (Z)‐7‐dodecenyl acetate in olfactometer assays. Adding nonanal to this two‐component mix also doubled male trap catches relative to the two‐component mix alone in cotton fields, whereas nonanal alone did not attract any moths. The addition of nonanal to each of three commercial pheromone lures also increased male catches by 53–135% in sorghum and cotton fields.ConclusionThe addition of nonanal to pheromone lures should improve surveillance, monitoring and control of FAW populations. © 2023 The Authors.

Toughness Amplification via Controlled Nanostructure in Lightweight Nano‐Bouligand Materials
Authors: Patel Zainab S. , Meza Lucas R. 
Published: March 2023

AbstractThe enhanced properties of nanomaterials make them attractive for advanced high‐performance materials, but their role in promoting toughness has been unclear. Fabrication challenges often prevent the proper organization of nanomaterial constituents, and inadequate testing methods have led to a poor knowledge of toughness at small scales. In this work, the individual roles of nanomaterials and nanoarchitecture on toughness are quantified by creating lightweight materials made from helicoidal polymeric nanofibers (nano‐Bouligand). Unidirectional ( = 0°) and nano‐Bouligand beams ( = 2°–90°) are fabricated using two‐photon lithography and are designed in a micro‐single edge notch bend (µ‐SENB) configuration with relative densities between 48% and 81%. Experiments demonstrate two unique toughening mechanisms. First, size‐enhanced ductility of nanoconfined polymer fibers increases specific fracture energy by 70% in the 0° unidirectional beams. Second, nanoscale stiffness heterogeneity created via inter‐layer fiber twisting impedes crack growth and improves absolute fracture energy dissipation by 48% in high‐density nano‐Bouligand materials. This demonstration of size‐enhanced ductility and nanoscale heterogeneity as coexisting toughening mechanisms reveals the capacity for nanoengineered materials to greatly improve mechanical resilience in a new generation of advanced materials.
