Rectangular array of electromagnetic vector sensors: tensor modelling/decomposition and DOA-polarisation estimation

In this study, the authors propose a fast quadrilinear decomposition algorithm for estimation of the directions-of-arrival and polarisations of the incident sources via a uniform rectangular array of electromagnetic vector sensors (EMVSs). Conventional quadrilinear alternating least squares (QALS), involves computationally intensive Khatri-Rao products in each iteration, to update the parameter matrices (factors). Moreover, QALS is more likely to fall in a local minimum and tends to take more steps before an acceptable solution, which further slows down the convergence and often mis-converges, thereby yielding meaningless results. To preserve the quadrilinearity, they arrange the measurements as a four-dimensional (4D) data (fourth-order tensor), from which a third-order sub-tensor (3D slice) can be obtained by fixing one index along any dimension. These slices are used to create new cost functions that are alternately minimised while updating the factors until convergence. They show that the rows of parameter matrices form the diagonal elements of a tensor, which capture the internal quadrilinearity of data and significantly reduce the cost function in few iterations only. Simulation results verify that the authors' algorithm holds faster convergence, does not mis-converge, provides parameter estimation accuracy similarly to the QALS and superior of the Estimation of Signal Parameters via Rotational Invariance Technique and propagator method.
A Generalized Parallel Quantum Inspired Evolutionary Algorithm Framework for Hard Subset Selection Problems: A GPQIEA for Subset Selection

Quantum-inspired evolutionary algorithms (QIEAs) like all evolutionary algorithms (EAs) perform well on many problems but cannot perform equally better than random for all problems due to the No Free Lunch theorem. However, a framework providing near-optimal solutions on reasonably hard instances of a large variety of problems is feasible. It has an effective general strategy for easy incorporation of domain information along with effective control on the randomness in the search process to balance the exploration and exploitation. Moreover, its effective parallel implementation is desired in the current age. Such a Generalized Parallel QIEA framework designed for the solution of Subset Selection Problems is presented here. The computational performance results demonstrate its effectiveness in the solution of different large-sized hard SSPs like the Difficult Knapsack Problem, the Quadratic Knapsack Problem and the Multiple Knapsack problem. This is the first such a generalized framework and is a major step towards creating an adaptive search framework for combinatorial optimization problems.
Dinosaur paleohistology: review, trends and new avenues of investigation

In the mid-19th century, the discovery that bone microstructure in fossils could be preserved with fidelity provided a new avenue for understanding the evolution, function, and physiology of long extinct organisms. This resulted in the establishment of paleohistology as a subdiscipline of vertebrate paleontology, which has contributed greatly to our current understanding of dinosaurs as living organisms. Dinosaurs are part of a larger group of reptiles, the Archosauria, of which there are only two surviving lineages, crocodilians and birds. The goal of this review is to document progress in the field of archosaur paleohistology, focusing in particular on the Dinosauria. We briefly review the “growth age” of dinosaur histology, which has encompassed new and varied directions since its emergence in the 1950s, resulting in a shift in the scientific perception of non-avian dinosaurs from “sluggish” reptiles to fast-growing animals with relatively high metabolic rates. However, fundamental changes in growth occurred within the sister clade Aves, and we discuss this major evolutionary transition as elucidated by histology. We then review recent innovations in the field, demonstrating how paleohistology has changed and expanded to address a diversity of non-growth related questions. For example, dinosaur skull histology has elucidated the formation of curious cranial tissues (e.g., “metaplastic” tissues), and helped to clarify the evolution and function of oral adaptations, such as the dental batteries of duck-billed dinosaurs. Lastly, we discuss the development of novel techniques with which to investigate not only the skeletal tissues of dinosaurs, but also less-studied soft-tissues, through molecular paleontology and paleohistochemistry—recently developed branches of paleohistology—and the future potential of these methods to further explore fossilized tissues. We suggest that the combination of histological and molecular methods holds great potential for examining the preserved tissues of dinosaurs, basal birds, and their extant relatives. This review demonstrates the importance of traditional bone paleohistology, but also highlights the need for innovation and new analytical directions to improve and broaden the utility of paleohistology, in the pursuit of more diverse, highly specific, and sensitive methods with which to further investigate important paleontological questions.
An Ergonomic Assessment Of Four Different Donor Nephrectomy Approaches For The Surgeons And Their Assistants

Introduction Open surgery is increasingly being replaced by laparoscopic approaches that are more demanding for the surgical team. The physical and mental workload of these approaches have not been quantified. Materials and methods A multicenter prospective study was performed evaluating the physical and mental stresses of 4 surgical approaches (open surgery [OS], standard laparoscopy [SL], hand-assisted laparoscopy [HAL], and robot-assisted laparoscopy [RAL]) for donor nephrectomy for the surgeon and their assistant. The Borg Scale was used to evaluate exertion in different body parts every 30 mins during surgery and the NASA-TLX score was used to evaluate overall workload. Results 264 nephrectomies were performed over a 33-month period and 258 questionnaires evaluating these surgeries were obtained. Surgeons experienced less left shoulder and arm exertion and left forearm and hand exertion, but greater lower back exertion, as measured by the Borg scale, with RAL. Leg exertion was significantly greater with OS. Assistant surgeons experienced increased exertion in the back, right shoulder and arm, and right forearm and hand with RAL. NASA Task load index (TLX) surgeon scores showed mental demand was similar for all 4 surgical approaches. Physical demand was lower and overall performance was higher with RAL. Discussion Four different nephrectomy surgical approaches were evaluated in a multicenter setting. Surgeon and assistant scores of physical exertions were generally in the “easy” range but confirmed that robotic surgery is an ergonomic progress compared to other techniques, except for the axial skeleton. Further, it degrades the working conditions for the assistant.
Warm seawater temperature promotes substrate colonization by the blue coral, Heliopora coerulea

Background Heliopora coerulea, the blue coral, is a reef building octocoral that is reported to have a higher optimum temperature for growth compared to most scleractinian corals. This octocoral has been observed to grow over both live and dead scleractinians and to dominate certain reefs in the Indo-Pacific region. The molecular mechanisms underlying the ability of H. coerulea to tolerate warmer seawater temperatures and to effectively compete for space on the substrate remain to be elucidated. Methods In this study, we subjected H. coerulea colonies to various temperatures for up to 3 weeks. The growth and photosynthetic efficiency rates of the coral colonies were measured. We then conducted pairwise comparisons of gene expression among the different coral tissue regions to identify genes and pathways that are expressed under different temperature conditions. Results A horizontal growth rate of 1.13 ± 0.25 mm per week was observed for corals subjected to 28 or 31 °C. This growth rate was significantly higher compared to corals exposed at 26 °C. This new growth was characterized by the extension of whitish tissue at the edges of the colony and was enriched for a matrix metallopeptidase, a calcium and integrin binding protein, and other transcripts with unknown function. Tissues at the growth margin and the adjacent calcified encrusting region were enriched for transcripts related to proline and riboflavin metabolism, nitrogen utilization, and organic cation transport. The calcified digitate regions, on the other hand, were enriched for transcripts encoding proteins involved in cell-matrix adhesion, translation, receptor-mediated endocytosis, photosynthesis, and ion transport. Functions related to lipid biosynthesis, extracellular matrix formation, cell migration, and oxidation-reduction processes were enriched at the growth margin in corals subjected for 3 weeks to 28 or 31 °C relative to corals at 26 °C. In the digitate region of the coral, transcripts encoding proteins that protect against oxidative stress, modify cell membrane composition, and mediate intercellular signaling pathways were enriched after just 24 h of exposure to 31 °C compared to corals at 28 °C. The overall downregulation of gene expression observed after 3 weeks of sustained exposure to 31 °C is likely compensated by symbiont metabolism. Discussion These findings reveal that the different regions of H. coerulea have variable gene expression profiles and responses to temperature variation. Under warmer conditions, the blue coral invests cellular resources toward extracellular matrix formation and cellular migration at the colony margins, which may promote rapid tissue growth and extension. This mechanism enables the coral to colonize adjacent reef substrates and successfully overgrow slower growing scleractinian corals that may already be more vulnerable to warming ocean waters.
Clinical Guidelines for the Surgical Management of Chronic Lateral Ankle Instability: A Consensus Reached by Systematic Review of the Available Data

Background: The surgical management of chronic lateral ankle instability (CLAI) has evolved since the 1930s, but for the past 50 years, the modified Broström technique of ligament repair has been the gold standard. However, with the development of arthroscopic techniques, significant variation remains regarding when and how CLAI is treated operatively, which graft is the optimal choice, and which other controversial factors should be considered. Purpose: To develop clinical guidelines on the surgical treatment of CLAI and provide standardized guidelines for indications, surgical techniques, rehabilitation strategies, and assessment measures for patients with CLAI. Study Design: A consensus statement of the Chinese Society of Sports Medicine. Methods: A total of 14 physicians were queried for their input on guidelines for the surgical management of CLAI. After 9 clinical topics were proposed, a comprehensive systematic search of the literature published since 1980 was performed for each topic through use of China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI), PubMed, Web of Science, EMBASE, and the Cochrane Library. The recommendations and statements were drafted, discussed, and finalized by all authors. The recommendations were graded as grade 1 (strong) or 2 (weak) based on the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) concept. Based on the input from 28 external specialists independent from the authors, the clinical guidelines were modified and finalized. Results: A total of 9 topics were covered with regard to the following clinical areas: surgical indications, surgical techniques, whether to address intra-articular lesions, rehabilitation strategies, and assessments. Among the 9 topics, 6 recommendations were rated as strong and 3 recommendations were rated as weak. Each topic included a statement about how the recommendation was graded. Conclusion: This guideline provides recommendations for the surgical management of CLAI based on the evidence. We believe that this guideline will provide a useful tool for physicians in the decision-making process for the surgical treatment of patients with CLAI.
Advances in the science and treatment of alcohol use disorder

Pharmacological and behavioral treatments exist for alcohol use disorder, but more are needed, and several are under development. Alcohol is a major contributor to global disease and a leading cause of preventable death, causing approximately 88,000 deaths annually in the United States alone. Alcohol use disorder is one of the most common psychiatric disorders, with nearly one-third of U.S. adults experiencing alcohol use disorder at some point during their lives. Alcohol use disorder also has economic consequences, costing the United States at least $249 billion annually. Current pharmaceutical and behavioral treatments may assist patients in reducing alcohol use or facilitating alcohol abstinence. Although recent research has expanded understanding of alcohol use disorder, more research is needed to identify the neurobiological, genetic and epigenetic, psychological, social, and environmental factors most critical in the etiology and treatment of this disease. Implementation of this knowledge in clinical practice and training of health care providers is also needed to ensure appropriate diagnosis and treatment of individuals suffering from alcohol use disorder.
MicroRNA-155-3p promotes breast cancer progression through down-regulating CADM1

Background/purpose Cell adhesion molecule 1 (CADM1) functions as a tumor suppressor and has been identified to be frequently inactivated in breast cancer, and closely associated with patients’ poor prognosis and advanced TNM stage. However, the mechanisms underlying CADM1 in breast cancer progression remains incompletely clear. miR-155, a predicted modulator of CADM1 was reported to be overexpressed in breast cancer, and its high expression level was closely related to the malignant progression of breast cancer. The present study aimed to explore whether miR-155-3p could modulate CADM1 expression and then involved in the progression of breast cancer. Methods The expression patterns of miR-155-3p in breast cancer tissues and cell lines were determined by RT-PCR technology. The relationship between CADM1 and miR-155-3p were determined by the luciferase gene reporter and Western Blot (WB) assays. Cell proliferation, apoptosis rates and tumorigenesis were determined by CCK-8, flow cytometry and in vivo xenotransplanation experiments, respectively. Results miR-155-3p was up-regulated in breast cancer tissues and cells when compared to the adjacent normal tissues and normal breast MCF 10A cells. The mRNA and protein levels of CADM1 showed opposite expression patterns to that of miR-155-3p expression detected, and miR-155-3p could negatively regulate CADM1 expression in breast cancer MCF-7 cells. Moreover, gain-of function assay showed that overexpression of miR-155-3p promoted cell proliferation, tumorigenesis and repressed cell apoptosis, but these effects were all significantly impaired when the cells were simultaneously transfected with OE-CADM1, the overexpressing vector of CADM1. Conclusion This study revealed that miR-155-3p could accelerate the progression of breast cancer via down-regulation of CADM1 expression.
Cellular accumulation and cytotoxic effects of zinc oxide nanoparticles in microalga Haematococcus pluvialis

Background Zinc oxide nanoparticles (ZnO NPs) are widely used in household and cosmetic products which imply an increased releasing of these particles into the environment, especially aquatic ecosystems, resulting in the need of assessing the potential toxic effects of ZnO NPS on the aquatic organisms, particularly on microalgae which form the base for food chain of aquatic biota. The present study has investigated the dose- and time-dependent cellular accumulation and the corresponding cytotoxic effects of increasing concentrations of ZnO NPs from 10–200 μg/mL on microalga Haematococcus pluvialis at an interval of 24 h for 96 h. Methods The scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX) was used to qualitatively detect the cellular accumulation of ZnO NPs in algal cells, while inductively coupled plasma optical emission spectrometry (ICP OES) was performed to quantify the cell associated-zinc in algal cells. The percentage of cell death, reduction in algal biomass, and loss in photosynthetic pigments were measured to investigate the cytotoxic effects of ZnO NPs on H. pluvialis. Extracellular and intracellular changes in algal cells resulted from the treatment of ZnO NPs were demonstrated through optical, scanning, and transmission electron microscopic studies. Results SEM-EDX spectrum evidenced the accumulation of ZnO NPs in algal biomass and ICP OES results reported a significant (p < 0.05) dose- and time-dependent accumulation of zinc in algal cells from 24 h for all the tested concentrations of ZnO NPs (10–200 μg/mL). Further, the study showed a significant (p < 0.05) dose- and time-dependent growth inhibition of H. pluvialis from 72 h at 10–200 μg/mL of ZnO NPs. The morphological examinations revealed substantial surface and intracellular damages in algal cells due to the treatment of ZnO NPs. Discussion The present study reported the significant cellular accumulation of ZnO NPs in algal cells and the corresponding cytotoxic effects of ZnO NPs on H. pluvialis through the considerable reduction in algal cell viability, biomass, and photosynthetic pigments together with surface and intracellular damages.
Disruptive variants of CSDE1 associate with autism and interfere with neuronal development and synaptic transmission

CSDE1 disruptive mutations are associated with autism. RNA binding proteins are key players in posttranscriptional regulation and have been implicated in neurodevelopmental and neuropsychiatric disorders. Here, we report a significant burden of heterozygous, likely gene-disrupting variants in CSDE1 (encoding a highly constrained RNA binding protein) among patients with autism and related neurodevelopmental disabilities. Analysis of 17 patients identifies common phenotypes including autism, intellectual disability, language and motor delay, seizures, macrocephaly, and variable ocular abnormalities. HITS-CLIP revealed that Csde1-binding targets are enriched in autism-associated gene sets, especially FMRP targets, and in neuronal development and synaptic plasticity–related pathways. Csde1 knockdown in primary mouse cortical neurons leads to an overgrowth of the neurites and abnormal dendritic spine morphology/synapse formation and impaired synaptic transmission, whereas mutant and knockdown experiments in Drosophila result in defects in synapse growth and synaptic transmission. Our study defines a new autism-related syndrome and highlights the functional role of CSDE1 in synapse development and synaptic transmission.

Background: Factors affecting social health, especially in young adults, are among the most important research priorities. Knowledge of social factors affecting young adults’ health will lead to understand them in the social context. The present study is aimed to explain the perspective of young adults on social factors affecting health. Methods: In the present qualitative content analysis study, semi-structured open interviews were conducted through targeted sampling of young volunteers aged 18–30 who were selected from Tehran Province. Interviews were recorded, transcribed, and analyzed. The inclusion criteria for participants were willingness to participate in the study and ability to express their personal experiences. Twenty-one data were collected through collection was done with individual in-depth interviews. Results: Using this qualitative approach, the present study was conducted to identify factors affecting social health from the perspective of young adults. The analysis led to the extraction of three main categories, each with two or three subcategories: expectations regarding the community, expectations regarding the family, and expectations regarding infrastructures. Conclusions: Our findings shown that social support considered as effective elements in providing social health of young adults. The evidence on controlling factors should be considered in promoting the social health of specific target groups. The results of the present study could be used for better planning of interventions in youth social health domains.
Cloning of a new HSP70 gene from western flowerthrips, Frankliniella occidentalis, and expression patterns during thermal stress

Frankliniella occidentalis (Pergande) is an invasive pest that endangers a wide variety of horticultural and agronomic crops. HSP70 is the most important member of the heat shock protein (HSP) family and plays an important role in insect thermal tolerance. In this study, a new gene encoding HSP70 from F. occidentalis, Fohsp706, was selected from the F. occidentalis transcriptome exposed to thermal stress (40 °C) and cloned by RT-PCR and RACE. Further characterization indicated that Fohsp706 localizes to the cytoplasm and does not contain introns. Quantitative real-time reverse transcriptase PCR indicated that Fohsp706 expression was significantly up-regulated by thermal stress; furthermore, there were significant differences in Fohsp706 expression in adults and second instar nymphs after heat stress. Our results indicated that Fohsp706 contributes to thermotolerance in F. occidentalis and provides another example of how this pest adapts to unfavorable environmental conditions.
Evaluation of methenamine for urinary tract infection prevention in older adults: a review of the evidence

Urinary tract infections (UTI) commonly occur in older adults and can lead to more severe, life-threatening infections. Physiological factors that change with age are thought to contribute to the increased frequency of UTI recurrence in older adults. Unfortunately, there are limited methods to prevent UTI in older adults, and utilization of antimicrobial agents for prevention can have many negative consequences. Methenamine has been proposed as a useful drug for the prevention of UTI as it works as a urinary antiseptic, safely producing formaldehyde to prevent bacterial growth while avoiding bacterial resistance. The objective of this review is to evaluate the existing literature and discuss the use of methenamine in older adults for prevention of UTI. A PubMed search was conducted to identify studies evaluating the effectiveness of methenamine to prevent UTI in older adults, and 10 publications were selected based on relevant criteria. Based on the literature, methenamine appears to be a safe and effective option to prevent UTI in older adults with recurrent UTI, genitourinary surgical procedures, and potentially long-term catheterization. Studies have not evaluated the safety of methenamine in patients with impaired renal function or CrCl <30 ml/min. When selecting a treatment approach to preventing UTI in older adults with adequate renal function, clinicians may consider methenamine as a viable option.
