Authors: Akram Mashal , Umair Muhammad , Yaqub Muhammad Atif , Ramay Shahid M. , Naseem Shahzad , Atiq Shahid
Published: August 2023

With the rise in eco-friendly energy needs, supercapacitors have become an essential option for energy storage devices. For this purpose, new and efficient electrode materials are required for use in supercapacitors with higher durability and longer storage lifespan. For this, transition metal oxides are preferred, owing to their high capacitance values, for energy storage in supercapacitors. In this context, LaMn1-xFexO3 (x = 0.0, 0.33, 0.66, and 1.0) are presented here with a better electrochemical response, prepared following sol−gel auto-combustion route to optimize the influence of Fe substitution at Mn-site in LaMnO3. X-ray diffraction technique confirms the formation of the orthorhombic phase for both LaFeO3 and LaMnO3. Cyclic voltammetry was performed at a constant potential window of −0.2 to 0.4 V and varying scan intervals (0.01−0.2 Vs−1). The oxidation/reduction peak occurrences revealed the pseudocapacitive behavior and the apparent Nyquist plot showed less charge transfer resistance. Thus, marvelous results expose the synthesized composition LaMn1-xFexO3 at x = 0.0, 0.33, 0.66, and 1.0, a promising material for the electrodes.

Bone marrow (BM) evaluation is highly important for the diagnosis of numerous hematological alterations in animals, especially cats, given their greater propensity for hematopoietic changes associated with retrovirus infections. This study aims to describe the main aspects of the BM of cats with different hematological conditions, comparing with reference intervals established from animals without hematological alterations and also with a previously established reference interval. To do so, we evaluated full blood and BM samples from 120 cats with no abnormalities on physical examination, negative for FeLV and FIV. Hemograms were performed from automated total cell and platelet and leukocyte differential counts in blood smears. BM samples were placed in Petri dishes; medullary spicules were selected to make up to eight cytological slides stained by the May–Grunwald–Giemsa technique, which were subjected to quantitative and cellular morphology evaluations. The cats were predominantly young, 64.2% female and 35.8% male. The average number of medullary spicules in samples was 13.7%, and density was 44%. In the BM quantitative analysis, prorubricytes and rubriblasts had higher quantities than the recommended one for all cats with or without hematological alterations. In all groups, lymphocytes were decreased, and cats with lymphocytosis were closest to the reference range, showing flame cells and Mott cells. The reference interval for the bone marrow cell count obtained from the samples in this work differs from previously established data, leading to different interpretations of the patient’s BM condition, according to the cell population observed and the reference interval used. This divergence strongly emphasizes the need to correlate clinical, epidemiological, hematological, and bone marrow data of each patient for a better understanding of the patient’s condition. The popularization of BM assessment is essential so that more reliable reference intervals can be established according to the population served by each pathologist and clinical laboratory.

Authors: Jacob Abiah , Coker Adeyemi , Stamenkovic Steven Aleksandar
Published: August 2023

Endometriosis is characterized by endometrial-like glands and stroma outside the uterine cavity, affecting women of reproductive age. Thoracic endometriosis syndrome (TES) is an entity producing a range of clinical and radiological manifestations, including catamenial pneumothorax, haemothorax, haemoptysis, and pulmonary nodules within the thoracic cavity or on the diaphragm. TES symptoms are nonspecific, warranting a high degree of clinical suspicion. Management includes hormone replacement therapy, surgical management, or a combination of both. We present a case of a 37-year-old woman who presented with TES and unilateral diaphragmatic palsy, managed with robotic-assisted thoracoscopic surgery and hormone replacement.
Preparation of TiO2 Grafted on Graphene and Study on their Photocatalytic Properties
Authors: Lin Longli , Shi Lihua , Liu Simei , He Jieyi
Published: August 2023

TiO2 has potential application prospects in the fields of environmental pollution control and energy conversion, while its characteristics including proneness to agglomeration and low activity affect practical applications. In view of this, P25 TiO2 and graphene were taken as raw materials to prepare the modified TiO2 catalyst. The modification mechanism of TiO2 was explained by characterizing the phase composition, microscopic morphology, and functional groups and analyzing the specific surface area and particle size. Then, the photocatalytic performance of the material was explored by taking methyl orange as the target to be degraded. Results show that TiO2 is well grafted to the laminated structure of graphene using physicochemical interactions among the introduced functional groups after modifying P25 TiO2 and graphene. This way, the 10.00 mg·L-1 methyl orange solution is almost completely degraded within 12 min at a reaction rate that is 1.81 times higher than that of P25 TiO2. Even after being used for 10 times, the performance still remains stable. The modification process is simple, and the method is reliable. Results can promote the practical application of TiO2 photocatalytic technology.

Published: August 2023

Thus, this research was conducted to evaluate the supplementation of heat-killed Lactobacillus plantarum at higher dosages and investigate the effect of heat-killed L. plantarum supplementation on the challenges of Streptococcus agalactiae. A feeding trial was conducted for 90 (initial average body weight of 12.52–12.69 g) days, while a disease challenge was conducted for 17 days. Dietary treatments were formulated to have a ranging level of heat-killed L. plantarum L-137: (1) control treatment without heat-killed L. plantarum, (2) diet containing 10 mg/kg heat-killed L. plantarum L-137 preparation (LP20, which contains 20% heat-killed L. plantarum L-137), (3) diet containing 20 mg/kg LP20, (4) diet containing 100 mg/kg LP20, and (5) diet containing 250 mg/kg LP20. All the diets were formulated to have equal values of protein and energy. Dietary supplementation of heat-killed L. plantarum L-137 improved tilapia growth performance and higher robustness against S. agalactiae infection. Therefore, a 10–20 mg/kg LP20 feed supplementation level is recommended to support the tilapia growth. In addition, an LP20 dietary supplementation level of 250 mg/kg feed is recommended for higher protection against S. agalactiae.

Published: August 2023

Purpose:

This phase Ib study defined the safety, MTD, and recommended phase II dose (RP2D) of regorafenib combined with vincristine and irinotecan (VI). Secondary objectives were evaluation of antitumor activity and pharmacokinetics (PK) of regorafenib and irinotecan.

Patients and Methods:

Patients aged 6 months to <18 years with relapsed/refractory solid malignancies [≥50% with rhabdomyosarcoma (RMS)] received regorafenib (starting dose 72 mg/m2/day) concomitantly or sequentially with vincristine 1.5 mg/m2 on days 1 and 8, and irinotecan 50 mg/m2 on days 1–5 (21-day cycle). Adverse events (AE) and tumor response were assessed. PK (regorafenib and irinotecan) were evaluated using a population PK model.

Results:

We enrolled 21 patients [median age, 10 years; 12, RMS; 5, Ewing sarcoma (EWS)]. The MTD/RP2D of regorafenib in the sequential schedule was 82 mg/m2. The concomitant dosing schedule was discontinued because of dose-limiting toxicities in 2 of 2 patients treated. Most common grade 3/4 (>30% of patients) AEs were neutropenia, anemia, thrombocytopenia, and leukopenia. The overall response rate was 48% and disease control rate [complete response (CR)/partial response/stable disease/non-CR/non-progressive disease] was 86%. Median progression-free survival was 7.0 months [95% confidence interval (CI), 2.9–14.8] and median overall survival was 8.7 months (95% CI, 5.5–16.3). When combined with VI, regorafenib PK was similar to single-agent PK in children and adults (treated with regorafenib 160 mg/day).

Conclusions:

Regorafenib can be combined sequentially with standard dose VI in pediatric patients with relapsed/refractory solid tumors with appropriate dose modifications. Clinical activity was observed in patients with RMS and EWS (ClinicalTrials.gov NCT02085148).

Published: August 2023

Background

Preliminary in vitro and early clinical experience of the Tenzing 7 delivery catheter demonstrated high success rates of aspiration catheter intracranial delivery with minimal complications. This study aimed to examine the efficacy, safety, and efficiency of the Tenzing 7 delivery catheter to deliver therapeutic devices in aspiration mechanical thrombectomy for acute ischemic strokes using clinical experience from multiple institutions.

Methods

We performed a retrospective analysis of prospectively collected data from patients with acute ischemic stroke treated with aspiration mechanical thrombectomy using the Tenzing 7 delivery catheter between January 2020 and July 2022 at 6 high volume stroke centers. Primary efficacy outcome was success in aspiration catheter delivery to the face of the thrombus, and primary safety end point was rate of procedural complication.

Results

Of a total of 176 patients (mean age 70.1±14.9 years, 56.3% female, 89.2% middle cerebral artery occlusions), first‐pass effect (modified Thrombolysis in Cerebral Infarction score≥2B) was achieved in 90/166 (54.2%) successfully revascularized patients. Tenzing 7 delivered the aspiration catheter of choice to the site of occlusion in 95.9% of cases; the clot was not crossed with Tenzing 7 in 69% of cases. Successful recanalization (modified Thrombolysis in Cerebral Infarction score≥2B) was achieved in 94.9% of cases requiring a median of 1 pass (interquartile range 1–3). Nonflow limiting vessel dissection unrelated to Tenzing 7 occurred in 4 patients (2.3%), and intracranial vessel perforation unrelated to Tenzing 7 occurred in 4 cases (2.3%).

Conclusion

This multicenter clinical experience using Tenzing 7 in mechanical thrombectomy demonstrated high rates of technical success and a modest complication rate, similar to the published rates of technical success with other thrombectomy techniques. The Tenzing 7 delivery catheter is effective and safe for the delivery of the aspiration catheter in patients undergoing thrombectomy for acute ischemic stroke.
Defensive behaviour plasticity in Ananteris mauryi Lourenço, 1982 (Scorpiones: Buthidae) facing different predator species

Published: August 2023

Small species often fall prey to a wide range of predators in their natural habitats, and therefore require behavioural strategies to mitigate predation rates. In this study, we investigated the defensive behaviour of Ananteris mauryi, a small-bodied scorpion, against different natural predator species. Behavioural trials were conducted with A. mauryi individuals facing two different predators, spider and scorpion. Our results show that A. mauryi altered their defensive acts depending on the predator type, swinging their telson, cleaning their pedipalps, and run more frequently when facing spiders than scorpions. Additionally, we observed variation in the duration of behaviours according to predator type, with stinging attempts being performed more frequently against scorpions and run and metasoma swinging against spiders. Our findings suggest that scorpions have the ability to modulate their defensive behaviour according to the type of predator they face.
Environmental Autonomy
Authors: Savaşan Zerrin
Published: August 2023

This article aims to get a new brand start to the autonomy debate by examining environmental autonomy (ea) as a new concept under international law (il). In this respect, firstly, it focuses on establishing why such a notion is needed, where the idea comes from, so, on which basis the article’s analysis has been built. Secondly, to conceptualise ea in legal terms, it makes research on two sub-debates involving the principle of self-determination and nonhuman rights approach. Finally, it concludes that although there is no tangible certain legal basis to apply such a concept under current il other than the terms of indigenous rights; developments in recent decades show that, ea debate, testing the boundaries of law, might truly have the potential to the development of literature beyond the anthropocentric paradigms; but also underlines the need for further work on its potential legal framework under il.
“A Native of Poland Professing the Arts in London”: The Unconventional Jewish Life and Thought of Solomon Yom Tov Bennett (1767–1838)
Authors: Ruderman David
Published: August 2023

This essay offers a new reconstruction of the fascinating life and works of Solomon Yom Tov Bennett (1767–1838), a Jewish engraver and biblical scholar who emigrated from Belarus via Copenhagen and Berlin to London. While Bennett’s intellectual path might appear similar to several other notable Polish Jewish immigrants to Western Europe, he is quite distinctive for his remarkable coadunation of art and thought, for his unusual focus on biblical studies, for opening social and intellectual connections with some of the most famous and accomplished Christian intellectuals of London, and for his self-determination and drive to complete his life-long ambition of serving Western civilization by rewriting and correcting the entire standard edition of the English Old Testament, a task of translation, he fervently believed, that could only be fulfilled by a learned Jewish Hebraist like himself.
The Apprenticeship System in the Caribbean
Authors: Heuman Gad
Published: August 2023

Slavery was abolished in the Anglophone Caribbean on August 1, 1834. On that date, the enslaved became legally free. However, the freedom of the enslaved was heavily circumscribed by the Apprenticeship system which followed immediately after August 1. Under the terms of this system, former slaves—now called apprentices—were required to work up to 45 hours per week for their former masters without compensation. Apprentices resisted the system at its outset; subsequently, they attempted to assert their rights as much as possible during the Apprenticeship period, even in the face of a highly oppressive system. Yet, like the enslaved, apprentices have left very little direct evidence in the form of letters or diaries. But because of their appearances before the stipendiary magistrates and in the reports generated about the Apprenticeship system, we can recreate aspects of their world and understand how apprentices sought to take advantage of Apprenticeship for their own benefit.

Published: August 2023

The objective of this study was to assess the diversity and distribution of large branchiopods in the Algerian Sahara and Hauts Plateaux. The survey identified a total of eleven species, classified into seven Anostraca, two Notostraca, and two Spinicaudata. Large branchiopods were found in 76.6% of the sites surveyed. In particular, new records of Triops granarius (Lucas, 1864) were obtained from the Tasilli N’Ajjer region (Central Sahara), while Eocyzicus saharicus (Gauthier, 1937) was added to the list of large branchiopods of Algeria, bringing the total number of species in Algeria to twenty-four. In addition, this study examines the latitudinal gradient of major branchiopod assemblages in Algeria, extending from the northern Mediterranean coast to the arid regions of the Sahara. The study identifies eight major assemblages of large branchiopods distributed across different ecoclimatic zones that occur along the latitudinal and longitudinal axes of the country. In addition, the study draws parallels between Algerian assemblages and those in neighboring Morocco and Tunisia.

Published: August 2023

The taxonomy of the genus Brachytrupes Serville, 1838, known as Giant Burrowing Crickets is revised. Brachytrupes includes thirteen species, with B. megacephalus Lefebvre, 1827 designated as type species to promote nomenclature stability. Brachytrupes membranaceus Drury 1773, is regarded as a nomen dubium. Furthermore, the present study provides a description of a new species Brachytrupes bapaensis Simeu-Noutchom, Kekeunou & Heller sp. nov. from West Cameroon, together with a species identification key and geographic distribution. Brachytrupes bapaensis sp. nov. can be distinguished from all other species of the genus by its black-brown body, pronotum smooth and black with a yellow spot on the lateral margin, posterior pronotum as wide as the anterior. Moreover, calling song with the syllable period around 8 ms and the syllable repetition rate near 115 Hz have been recorded. This review has wide implications for the knowledge of edible insects as well as their distribution.
A reassessment of the Andean genus Myopella Malloch (Diptera: Anthomyiidae)
Authors: MICHELSEN VERNER
Published: August 2023

The small Andean genus Myopella Malloch with two included species, M. angustifrons Malloch and M. appendiculata (Stein), is re-examined with special attention to the morphology of the male and female abdomen and terminalia. Adult morphology corroborates the current position of Myopella as an Andean endemic genus of Anthomyiidae, but its position within the anthomyiid tree remains in doubt despite the newly attained morphological knowledge. The status of the name Myopinella Michelsen, as proposed recently to replace for the preoccupied name Myopella Malloch, is clarified.
Traumatic Endograft Fracture With Subsequent Type IIIb Endoleak
Authors: Robbins Justin M. , Mendoza Limayre B. , Pecchioni Louisa L.
Published: August 2023

Abdominal aortic aneurysm (AAA) repair is commonly treated via endovascular aneurysm repair (EVAR). A known complication of EVAR is an endoleak: types I to IV. Type III endoleaks have been shown to have a relative risk of 8.95 for late rupture requiring prompt treatment. These endoleaks have been found to be caused by over dilation of the main body causing graft fabric distortion, fractures of metallic struts, fabric wear from chronic micromotion, fabric tears, and suture breakage. We present a case of traumatic EVAR fracture with subsequent type IIIb endoleak after blunt abdominal trauma. This highlights the need for close evaluation of endografts after abdominal trauma. These traumatic events can lead to traumatic fracture of endografts creating endoleaks that if not treated promptly can lead to rupture.
New joint probabilistic data association algorithm based on variational Bayesian adaptive moment estimation
Authors: Hu Zhentao , Tian Liuyang , Hou Wei , Yang Linlin
Published: August 2023

To improve the accuracy of multiple target tracking in the clutter environment, a new joint probabilistic data association (JPDA) algorithm based on variational Bayesian adaptive moment estimation is proposed. First, considering the existence of measurements, the posterior distribution of the target state in JPDA is composed of two parts of probability weighting, that is, the posterior distribution of the target state that the real measurement exists in the association gate and the posterior distribution of the target state that the real measurement does not exist in the association gate. By combining the conjugate properties of the prior and posterior distributions, the prior distributions of the target state in the two cases are classified to provide more accurate a priori information to filter, so as to improve the accuracy of data association. Second, considering the coupling effect between state estimation and data association process, combined with variational Bayesian inference, the problem of minimizing Kullback–Leibler divergence is transformed into the problem of maximizing the evidence lower bound, thereby effectively measuring the distance between the posterior distribution of target state estimation and the real posterior distribution, so as to improve the accuracy of data association again from the perspective of optimizing nonlinear filter. Finally, the adaptive momentum estimation strategy is introduced to iteratively solve the variable distribution that meets the maximization of the evidence lower bound, and the optimization of the posterior distribution of the target state is completed. Theoretical derivation and simulation experiments are conducted to verify the feasibility and effectiveness of the algorithm.

Published: August 2023

Objective

To compare the effectiveness of a McKenzie Method intervention in patients with sciatica with guideline-based patient education.

Design

Multi-centre, assessor-blinded, parallel-group, randomised trial

Setting

Two tertiary hospitals providing operative spinal care.

Subjects

Sciatica patients with magnetic resonance imaging-confirmed lumbar disc herniation compressing a nerve root.

Interventions

The McKenzie group received specific back exercises for seven visits combined with an educational book, and the Control group received a single session of self-management guidance according to usual practices.

Main measures

The primary outcome was the number of surgical operations. Secondary outcomes were pain measured using the Visual Analogue Scale, disability using the Oswestry Disability Index and health-related quality of life using a RAND-36 questionnaire at baseline and 24-month follow-up.

Results

Altogether 66 patients, mean age of 43 years, of which 50% were females with long-lasting sciatica, mean 16 weeks, were randomised to two groups. Nineteen patients (29%) had surgery. There was no significant difference in surgery rates between the groups. Back and leg pain decreased, and disability improved in both groups. Health-related quality of life improved in six dimensions out of eight in both groups. There were no significant between-group changes in the patient-reported outcomes at the follow-up.

Conclusions

Multiple sessions of McKenzie-based back exercises with a McKenzie-specific patient's educational book produced effects equal to guideline-based advice at long-term follow-up. However, the power of these results is diminished due to the small patient population and confounding factors.

Published: August 2023

Urinary Tract infection (UTI) is one of the most common infections worldwide, patients present to multiple different specialities in the community, primary and secondary care. Antibiotics are considered standard first line therapy in the treatment of urinary tract infections, however there is an alarming rise in global antibiotic resistance rates, so much so that the World Health Organisation has labelled antibiotic resistance as one of the biggest challenges to public health in our lifetime, publishing a global action plan to tackle this challenge. As a result, there is an increasing need to discover non-antibiotic alternatives, recently a number of novel therapies have been introduced into clinical practice. These are divided into oral, topical, intravesical and immunomodulation therapies. The aim of this paper is to summarise the current non-antibiotic treatments as a practical guide to utilise in patient care.

Published: August 2023

Objective

There is increasing interest in early intervention and detection strategies for youth at-risk of developing a serious mental illness (SMI). Little is known about early factors that may be related to the later development of a SMI; thus, the aim of this study was to determine what clinical factors might relate to the development of in this study psychosis, bipolar disorder and severe or recurrent major depression in at-risk youth.

Method

The sample consisted of 162 youth aged 12–26 years at different stages of risk. Thirty-one participants developed a SMI during the study. Those who made a transition were compared on a range of baseline clinical and functional measures with those who did not make the transition. A Cox regression model was used to assess the association between measures and later development of a SMI.

Results

Female sex, attenuated psychotic symptoms as assessed with the Scale of Psychosis-Risk Symptoms (SOPS) and ratings on the K-10 Distress Scale, were found to be significantly associated with the later transition to mental illness. Females were 2.77 times more likely to transition compared to males. For the SOPS and K-10 scales, there is a 14% increase in the transition rate relative to a one-scale increase in SOPS and a 7% increase in the transition rate relative to a one-point increase in the K-10.

Conclusions

Results from these longitudinal data provide further insight into the specific clinical measures that may be pertinent in early detection of mental illnesses.

Published: August 2023

This work deals with the optimization of the machining process of EN-GJL-250 gray cast iron with a CBN/Tin-coated insert. The multiobjective optimization was performed by four methods, in order to find the optimal cutting conditions (cutting speed (Vc) , feed rate ( f), and depth of cut (ap)) that would satisfy the goals of improving surface quality, minimizing power consumption, and maximizing productivity simultaneously. The aim is to evaluate the performance of different techniques, namely desirability function approach, Grey relational analysis, technique of order preference similarity to the ideal solution (TOPSIS), and nondominated sorting genetic algorithm coupled with TOPSIS. The outcomes revealed that the methods propose different solutions, where significant divergences were mainly observed in power consumption and material removal rate objectives. This raises the issue of selecting the most appropriate optimization method for industrial needs and confirms the need for further efforts in this field, i.e. optimization of the machining process.

Published: August 2023

Virtual collaboration is crucial nowadays, while shared attention plays a vital role in problem-solving. This study examines the relationship between blink synchronization, an index of shared attention, and problem-solving performance in a virtual setting. Thirty-seven dyadic teams completed a familiarization and problem-solving task. We hypothesized that blink synchronization would be established during familiarization, impacting performance. Additionally, we expected blink synchronization to increase over time. Results revealed that blink synchronization predicted teams’ problem-solving performance, and blink synchronization increased over time. Our findings shed light on the importance of blink synchronization for shared mental modeling and offer practical insights for virtual teamwork.
Improving Laboratory Result Retrieval Times Within the Home Health Setting
Authors: Sheppard Allison F.
Published: August 2023

This quality improvement project focuses on decreasing laboratory result retrieval times within a 6-month period at a rural home health setting. Prior to implementation, 73% of all laboratory results were not received within 24 hours (72 hours for cultures). Interventions included Lean Six Sigma methodologies (process mapping and process redesign) and Plan-Do-Study-Act to reduce laboratory result retrieval times. Data analysis included descriptive statistics including means, averages, and percentages for the primary outcome of laboratory result retrieval time. 119 participants included all patients who had laboratory specimens collected by home health staff during the project timeline. Laboratory result delays ≥24/72 hours decreased from 73% (29/40) to 14% (11/79). Furthermore, 25% (10/40) of labs were delayed ≥5 days pre-implementation and 0% post-implementation. Abnormal laboratory results with delayed treatment decreased from 28% (11/40) to 5% (4/79). Provider notification within 24 hours of an abnormal laboratory result increased from 0% (0/13) to 75% (6/8). Hospitalization rates within 30 days of an abnormal result was 15% (6/40) pre-implementation and decreased to 5% (4/79) post-implementation.
‘Most people have no idea what autism is’: Unpacking autism disclosure using social media analysis
Authors: Edwards Chris , Love Abigail M A , Jones Sandra C , Cai Ru Ying , Nguyen Boyd Thai Hoang , Gibbs Vicki
Published: August 2023

Autism disclosure can be a complicated decision that autistic people experience. Positive outcomes can include feelings of acceptance and support, but negative outcomes can include stigma and discrimination. Although a surge in research on this topic has led to more understanding around autism disclosure, the methodologies used may have limited who was contributing to the conversation and data. To overcome this, we analyzed 3 years (2020−2022) of social media data (Reddit and Twitter) as this was public information that did not rely on researcher data collection. Reflexive thematic analysis of 3121 posts led to the generation of four themes: People do not understand autism (with experiences related to employment, dating, healthcare and mental health), autistic people just want privacy and respect, autistic people can lead us forward and non-autistic people need to assume more responsibility. We discuss how autistic adults experience the impact of society’s lack of understanding of autism on a daily basis whether they disclose or not, and that it is everybody’s responsibility to challenge negative stereotypes and promote a more inclusive society.

Lay abstract

Autism disclosure – that is sharing their autism diagnosis or identity with a person or people – is a difficult decision for many autistic people. While telling people they are autistic can be positive and helpful, it can also create a lot of problems. What we have learnt is that disclosure is really complicated. Rather than asking research participants questions about what might happen, we looked at what people were saying on public social media posts (Reddit and Twitter) about what did happen. We used three years of posts that were related to autism disclosure from a wide range of adults (autistic and non-autistic). Four main ideas were created from our data, with the key finding being that society does not understand autism. This lack of understanding creates problems for autistic people in work, dating, healthcare and mental health. The remaining ideas were that autistic people should have privacy and be treated with respect, that autistic representation can help society and that non-autistic people need to do more to help autistic people. Our findings support that society needs to do more through autism advocacy, better media representation and more public role models. Increasing the accuracy of understanding of autism across society will mean that autistic people can feel safer to disclose if they want to.
A modal estimation method of rotating blade based on compressed sensing and blade tip timing
Authors: Zheng Hua , Fang Guanyu , Wu Zhenglong , Duan Shiqiang , Zhou Jiangtao
Published: August 2023

Structural modal estimation has consistently remained one of the most crucial areas of research in mechanical vibration analysis and signal processing. It is imperative to accurately monitor the vibration signals of rotor blades and their corresponding structural modal parameters. Blade tip timing (BTT) is a promising approach used to measure vibration and monitor the health of blades. However, most existing BTT methods focus on frequency accuracy, neglecting damping, a key physical quantity that represents the strength of the structure. This research focuses on damping modal estimation of blade vibration and proposes a sparse reconstruction algorithm based on a two-dimensional Laplace wavelet family, which addresses the inherent under-sampled problem of BTT technology while enabling estimations of both the structural modal frequency and modal damping of the blades. Firstly, the proposed algorithm is achieved by designing a Laplace wavelet dictionary based on prior information and using a convex optimization objective function with a regularization term. Secondly, Laplace wavelet dictionary matches the signal better than the traditional Fourier dictionary based on the similarity between the damped vibration signal and the Laplace wavelet, then a sparser representation vector can be obtained. Moreover, the research object is not limited to a single blade, but can be easily expanded to multiple stages and multiple rotating blades monitored simultaneously. Finally, the simulation and physical test results indicate that the proposed method exhibits high reconstruction accuracy, reliability, and anti-noise abilities.

This work investigates the effectiveness of using convolutional neural networks (CNNs) and instantaneous displacement measurements for damage identification in beams. The study involves subjecting laboratory beams to eight distinct damage scenarios and capturing the vertical positions of 60 points along the beam length during free-vibration tests using a high-speed camera. The data obtained was subsequently used to train a CNN in a supervised manner to estimate the level of damage at each point. Results showed that the CNN models were able to correctly localize and quantify the damage levels when trained on data from all damage scenarios. The soundness of the proposed methodology was demonstrated in a robustness assessment, where all eight damage scenarios were correctly identified even when two of them were excluded from the training dataset.
Period Poverty: An Epidemiologic and Biopsychosocial Analysis
Authors: Casola Allison R. , Luber Kierstin , Riley Amy Henderson
Published: August 2023

In the United States, approximately one in five persons experience period poverty, defined as the inability to obtain resources needed for healthy, safe, and dignified menstrual management. Limited access to an inadequate number of menstrual supplies may lead to longer-than-recommended use, which can increase skin chafing, disruption of vaginal flora, and intravaginal toxin overgrowth. However, period poverty goes beyond simply having enough menstrual products and can encompass the embarrassment, stigma, shame, and barriers in conversation surrounding menstruation. Discussion and critical examination of the multilayered attributes surrounding period poverty have been intermittent in academic literature, particularly from a domestic lens. Thus, this narrative review and theoretical analysis aimed to describe the epidemiology of period poverty and analyze its biological, socio-emotional, and societal implications. We applied a descriptive epidemiology approach of person, place, and time, and employed a social-ecological lens to examine risk factors. Our findings describe the incidence, distribution, and possible ways to alleviate period poverty. Practitioners, medical providers, and public health professionals may have limited knowledge of period poverty, what it entails, and who it impacts, but they have great potential to address it and associated menstrual inequities in their work. With its widespread implications for psychosocial and community-level health, this phenomenon needs urgent attention to promote menstrual equity as an issue of human rights and social justice. We conclude with research and policy recommendations for alleviating period poverty.

Published: August 2023

Introduction

The aim of this study is to report the early and late outcomes of cryopreserved saphenous vein (CSV) in redo infrainguinal bypass and to investigate possible predictors of primary patency loss.

Methods

All patients who underwent a redo bypass for critical limb ischemia from January 2010 to December 2020 were reviewed. Early and late complications were analyzed and included. The endpoints of the study were all cause mortality, major limb amputation, and primary patency (PP).

Results

Data were collected from 95 patients. Among the entire cohort, 16 (16.8%) patients received a cryopreserved vessel bypass with anastomosis in the popliteal artery and 79 (83.2%) patients had cryopreserved vessel bypasses with distal anastomosis in tibial vessels. Median duration of follow-up was 73 months; during this, period estimated survival at 5 years was 80.5 ± 4% (95% CI, 78.0–91.2) and estimates of freedom from limb amputation was 90.3 ± 3.2% (95% CI, 87.3–98.1). Overall, the estimated primary patency of the bypass was 43.7 ± 6.7% (95% CI, 30.2–51.4). On multivariable analysis, intraprocedural tibial vessel angioplasty (HR = 2.3, p = 0.01), distal anastomosis in tibial vessels (HR = 3.6, p = 0.36), and the use of a composite graft (HR = 2.4, p = 0.01) were independently associated with loss of PP.

Conclusions

The use of CSV in redo bypass is an effective strategy in salvaging threatened lower extremities and in preventing or delaying limb amputation. Our results confirm that further attempts at revascularization are generally appropriate, even in technically changing patients.
Plagiarism in Higher Education (PLAGiHE) within Sub-Saharan Africa: A systematic review of a decade (2012–2022) literature

The purpose of this study was to map the distribution of publications on plagiarism among higher educational institutions in sub-Saharan Africa (SSA). Studies reviewed were based on 171 plagiarism related publications within a decade (2012–2022). Findings revealed that most plagiarism related articles were published in 2016. Additionally, a majority of the studies (53) were from Nigeria and Ghana (23). Most of the articles focused on students’ and faculty’s awareness of plagiarism, and institutional prevention of plagiarism, but were rather marginal on challenges involved in preventing plagiarism, as well as effects of plagiarism. Dominant forms of plagiarism were self-plagiarism, branded plagiarism and commission plagiarism. However, major causes of plagiarism comprised easy access to digital information and resources; poor supervision of students; pressure on academics to publish for promotion; and insufficient skills development regarding ethical academic writing. Additionally, plagiarism preventive software and policies on plagiarism were the main ways of preventing plagiarism. Finally, in fighting plagiarism, higher educational institutions in SSA encountered challenges such as lack of well-trained academic experts to detect and report plagiarism cases; reluctance on the part of technical administrative staff to investigate works for traces of plagiarism; and low plagiarism detection skills from project supervisors. Based on the findings, recommendations are made to stakeholders for future research, policy and practice.
A thermoregulated phase-transfer ruthenium nanocatalyst for the atmospheric hydrogenation of α,β-unsaturated ketones
Authors: Gao Bin , Wang Yanhua
Published: August 2023

The selective hydrogenation of chalcone to dihydrochalcone under atmospheric hydrogen pressure is investigated using a thermoregulated phase-transfer ruthenium nanocatalyst, representing the first ruthenium nanocatalyst used for this reaction. Under the optimal conditions, the conversion of chalcone into dihydrochalcone and the selectivity are 98% and >99%, respectively. The ruthenium catalyst can be easily separated from the product and recycled three times without any decrease in the conversion or selectivity. The turnover frequency is higher than that of a reported ruthenium complex catalyst. The thermoregulated phase-transfer ruthenium nanocatalyst is also applied for the atmospheric hydrogenation of other α,β-unsaturated ketones.
How can Squadland motivate people to adopt sustainable behaviours through its metaverse?

Published: August 2023

Squadeasy, founded in France in 2014 with a move-to-earn app, launched a metaverse called Squadland in 2022, with a goal of increasing the company’s positive impact on the planet. When app users engaged in fitness activity in the real world, they earned tokens to buy land and other digital assets (NFTs) in Squadland, thereby improving the environment both inside the app and in the real world; Squadeasy bought land in the real world to mirror users’ actions in the metaverse. In this way, users could contribute to positive social change and have a sustainable effect on the world. This case discusses users’ motivations to engage in this metaverse, through the lens of Self Determination Theory. First, rather than fun and rewards, identified regulation is the relevant motivation to trigger commitment to the metaverse as it related to personal values and self-identity. Second, three external situational factors (autonomy, competence, and relatedness) positively increase commitment and will help users stay with the app. The metaverse fits well with these three external situational factors and can help achieve actual sustainable change.
Cold agglutinin disease: A case report with atypical clinical findings
Authors: Balaja Warren , Schmidt Paul , Fenando Ardy
Published: August 2023

A female in her 60s presented to the allergy and immunology clinic for further investigation of ongoing dermatitis. She presented with chronic acrocyanosis, mainly in her left lower extremity, extending distally from her mid thigh with concurrent ulcerations in her foot resulting in immobility secondary to pain. She experienced these symptoms for years without a definitive diagnosis. The lack of diagnosis was due, in part, to her atypical symptoms and laboratory findings that required a high level of clinical suspicion to diagnose. Extensive autoimmune workup was largely unrevealing with the exception of a cold agglutinin titer of 1:250 and a positive anticomplement C3b direct antiglobulin test. A diagnosis of cold agglutinin disease was made and treatment with rituximab monotherapy was initiated.

The skin is known to be the largest organ in the human body, while also being exposed to environmental elements. This indicates that skin is highly susceptible to physical infliction, as well as damage resulting from medical conditions such as obesity and diabetes. The wound management costs in hospitals and clinics are expected to rise globally over the coming years, which provides pressure for more wound healing aids readily available in the market. Recently, nanomaterials have been gaining traction for their potential applications in various fields, including wound healing. Here, we discuss various inorganic nanoparticles such as silver, titanium dioxide, copper oxide, cerium oxide, MXenes, PLGA, PEG, and silica nanoparticles with their respective roles in improving wound healing progression. In addition, organic nanomaterials for wound healing such as collagen, chitosan, curcumin, dendrimers, graphene and its derivative graphene oxide were also further discussed. Various forms of nanoparticle drug delivery systems like nanohydrogels, nanoliposomes, nanofilms, and nanoemulsions were discussed in their function to deliver therapeutic agents to wound sites in a controlled manner.
