Published: June 2023

AbstractThrough this study, an attempt was made to produce concrete beams from self‐compacting concrete (SCC) contain expanded polystyrene (EPS) beads as coarse aggregate and waste plastic fibers (WPFs) produced from cutting disposed packing straps in site. The beams were designed according to ACI‐318‐14, where three different reinforcement ratios were chosen for the purpose of checking the conductance of thresholds made of this type of environmentally friendly concrete under bending loads. The use of EPS with WPFs had a significant positive effect in reducing the density of concrete, and the highest percentage of reduction was equal to (38.46%). Using WPFs had a positive effect in increasing the flexural toughness of concrete prisms, and the maximum increment was equal to (180%) compared with these made from the reference mix. The results proved the possibility of producing lightweight concrete from the use of EPS waste and WPFs, three of which are structurally can be classified as lightweight concrete combination of normal weight and lightweight aggregates according to specifications requirements of ASTM330/330M‐14. Reinforced lightweight SCC beams behaved under flexural loads similar to the reinforced concrete beams made from normal weight concrete counterparts under flexural loads.
Numerical study on the structural performance of the continuous concrete slabs reinforced with hybrid BFRP/steel bars

Published: June 2023

AbstractThis study is mainly focused on the behavior of continuous concrete slabs reinforced with hybrid bars. Moment redistribution is a specific phenomenon in statically indeterminate structures due to the existence of redundant constraints and non‐uniform flexural stiffness of the reinforced concrete (RC) members. In this paper, a numerical one‐factor‐at‐a‐time parametric study was conducted using ABAQUS software to intensely understand the impact of several parameters on the performance of the hybrid RC continuous slabs. The investigated parameters were reinforcement type and ratio, FRP‐to‐steel ratio, and arrangement of reinforcement. The analysis results showed that the difference between sagging and hogging axial stiffness is the most influential parameter on the moment redistribution of hybrid‐RC continuous slabs. In addition, increasing the amount of reinforcement ratio at the mid‐span section is more effective in enhancing the load capacity of the slabs than over middle support section. Based on the obtained numerical results, some modifications to the Tarek et al. equations were proposed to be valid for hybrid‐RC continuous slabs. The presented modifications yielded good agreement with the numerical results predicting the moment redistribution of continuous concrete slabs with hybrid reinforcement.
Energy planning in sub‐Saharan African telecom networks: Decision support using a soft systems methodology
Authors: Ceriano Mbiika , Lalk Jörg , Thopil George Alex 
Published: June 2023

AbstractThis research paper narrates the application of the soft systems methodology (SSM) as a problem structuring tool, as well as the first step of a methodological approach that will provide decision support based on multi‐criteria decision analysis in the planning of energy for telecom networks across sub‐Saharan Africa. To ensure applicability of the methodology to a real‐world issue, an international telecom tower company based in East Africa was selected as the case study. The SSM is utilized to characterize the decision problem context precisely, identify major stakeholder groups and their connections, and to discover each one's interests. This helps to achieve appropriate and holistic energy planning and management unlike the current trends which employ a reductionist approach. The outcome of the work leads to a model using SSM where stakeholder inputs can be captured, for the telecom company.
Harnessing Radicals in Confined Supramolecular Environments Made Possible by MOFs
Authors: Li Mochen , Zhang Tiexin , Shi Yusheng , Duan Chunying 
Published: June 2023

AbstractResearching and utilizing radical intermediates in organic synthetic chemistry have innovated discoveries in methodology and theory. Reactions concerning free radical species opened new pathways beyond the frame of the two‐electron mechanism while commonly characterized as rampant processes lacking selectivity. As a result, research in this field has always focused on the controllable generation of radical species and determining factors of selectivity. Metal‐organic frameworks (MOFs) have emerged as compelling candidates as catalysts in radical chemistry. From a catalytic point of view, the porous nature of MOFs entails an inner phase for the reaction that could offer possibilities for the regulation of reactivity and selectivity. From a material science perspecti ve, MOFs are organic‐inorganic hybrid materials that integrate functional units in organic compounds and complex forms in the tunable long‐ranged periodic structure. In this account, we summarized our progress in the application of MOFs in radical chemistry in three parts: (1) The generation of radical species; (2) The weak interactions and site selectivity; (3) Regio‐ and stereo‐selectivity. The unique role of MOFs play in these paradigms is demonstrated in a supramolecular narrative through the analyses of the multi‐constituent collaboration within the MOF and the interactions between MOFs and the intermediates during the reactions.

Published: June 2023

AbstractBackgroundAnimal‐related injuries pose a significant risk to the veterinary profession. This study aimed to describe the incidence, demographics, context and consequences of animal‐related injuries at UK veterinary schools.MethodsA multicentre audit of accident records (2009–2018) across five UK veterinary schools was performed. Injury rates were stratified by school, demographics and species. The context and cause of the injury were described. Multivariable logistic models explored factors associated with medical treatment, hospital visits and time off work.ResultsAn annual rate of 2.60 (95% confidence interval 2.48–2.72) injuries per 100 graduating students was calculated, varying between veterinary schools. Injuries were more frequently recorded in staff than students, and there were significant differences between staff and students in the activities performed preceding injury. Cats and dogs were associated with the highest number of reported injuries. However, injuries associated with cattle and horses were the most severe, with significantly higher hospital attendances and more time off work taken.LimitationsData were based on reported injuries and likely underestimate the true injury rate. The population at risk was hard to quantify as population size and exposure were variable.ConclusionFurther research is recommended to explore the clinical and workplace management, including recording culture, of animal‐related injuries among veterinary professionals.
Critical perspectives on leadership identity development
Authors: Chunoo Vivechkanand S. , Torres Maritza 
Published: June 2023

AbstractThis article draws on critical race theory, intersectionality, critical feminism, queer and indigenous paradigms to critique existing approaches to leader/ leadership identity development (LID) and to illuminate how people from marginalized and oppressed communities can experience more just and equitable pathways to leadership. It offers recommendations for practice about how to create new possibilities for LID that counters patriarchal, white supremacist, hetero, and cis normative contexts. Liberatory pedagogies are suggested as ways to center social justice in LID.

AbstractThis article addresses the limitations of the existing leadership identity development literature and offers suggestions for extending the scope of knowledge and understanding of the topic to evolve leadership education research and practice. Authors suggest utilizing multi‐level, complexity, and systems views in the study of leadership identity development as a way to explore beyond constructivist, individual‐focused conventions that undergird the extant literature. It concludes with considerations for leadership educators to explore in efforts to expand and evolve their teaching, research, and practice related to leadership identity development.
Neutrinoless double beta decay and < η > mechanism in the left-right symmetric model
Authors: Fukuyama Takeshi , Sato Toru 
Published: June 2023

Abstract
The neutrinoless double beta decay is studied in the framework of left-right symmetric model. The coexistence of left and right handed currents induces rather complicated interactions between the lepton and hadron sectors, called < λ > mechanism and < η > mechanism in addition to the conventional effective neutrino mass < mν > mechanism. In this letter, we study the possible magnification of < η > mechanism and the relatively vanishing of < λ > mechanism. The importance to survey 0νββ decay of different nuclei for specifying new physics beyond the Standard Model is also discussed.

Abstract
We study the correlation function between one single-trace scalar operator and a circular Wilson loop in the 4d$$ \mathcal{N} $$
N
= 2 superconformal field theory with gauge group SU(N) and matter transforming in the symmetric and anti-symmetric representations. By exploiting supersymmetric localization, we resum the perturbative expansion of this correlator in the large-N ’t Hooft limit. Furthermore, using both analytical and numerical techniques, we provide a prediction for the leading term of its strong coupling expansion and we compare this prediction to numerical Padé resummations of the perturbative series.

The 5-HT1A receptor biased agonists, NLX-204 and NLX-101, display ketamine-like RAAD and anti-TRD activities in rat CMS models
Authors: Papp Mariusz , Gruca Piotr , Lason Magdalena , Litwa Ewa , Newman-Tancredi Adrian , Depoortère Ronan 
Published: June 2023

Abstract
Objectives
NLX-101 and NLX-204 are highly selective serotonin 5-HT1A ‘biased’ agonists, displaying potent and efficacious antidepressant-like activity upon acute administration in models such as the forced swim test.

Methods
we compared the effects of repeated administration of NLX-101, NLX-204 and ketamine in the chronic mild stress (CMS) model of depression, considered to have high translational potential, on sucrose consumption (anhedonia measure), novel object recognition (NOR; working memory measure) and elevated plus maze (EPM; anxiety measure) in male Wistar and Wistar-Kyoto rats (the latter being resistant to classical antidepressants).

Results
in Wistar rats, NLX-204 and NLX-101 (0.08–0.16 mg/kg i.p.), like ketamine (10 mg/kg i.p.) dose-dependently reversed CMS-induced sucrose intake deficit from treatment Day 1, with nearly full reversal observed at the higher dose at Days 8 and 15. These effects persisted for 3 weeks following treatment cessation. In the NOR test, both doses of NLX-101/NLX-204, and ketamine, rescued the deficit in discrimination index caused by CMS on Days 3 and 17; all three compounds increased time spent in open arms (EPM) but only NLX-204 achieved statistical significance on Days 2 and 16. In Wistar-Kyoto rats, all 3 compounds were also active in the sucrose test and, to a lesser extent, in the NOR and EPM. In non-stressed rats (both strains), the three compounds produced no significant effects in all tests.

Conclusions
these observations further strengthen the hypothesis that biased agonism at 5-HT1A receptors constitutes a promising strategy to achieve rapid-acting/sustained antidepressant effects combined with activity against TRD, in addition to providing beneficial effects against memory deficit and anxiety in depressed patients.
Globalization of partial actions of semigroups
Authors: Kudryavtseva Ganna , Laan Valdis 
Published: June 2023

AbstractWe propose two universal constructions of globalization of a partial action of a semigroup on a set, satisfying certain conditions which arise in Morita theory of semigroups. One of the constructions is based on the tensor product of a partial semigroup act with the semigroup and generalizes the globalization construction of strong partial actions of monoids due to Megrelishvili and Schröder. It produces the initial object in an appropriate category of globalizations of a given partial action. The other construction involves $${\textrm{Hom}}$$
Hom
-sets and is novel even in the monoid setting. It produces the terminal object in an appropriate category of globalizations. While in the group case the results of the two constructions are isomorphic, they can be far different in the monoid case.

Published: June 2023

Abstract
Purpose
Isolated REM sleep behaviour disorder (iRBD) patients are at high risk of developing clinical syndromes of the α-synuclein spectrum. Progression markers are needed to determine the neurodegenerative changes and to predict their conversion. Brain imaging with 18F-FDG PET in iRBD is promising, but longitudinal studies are scarce. We investigated the regional brain changes in iRBD over time, related to phenoconversion.

Methods
Twenty iRBD patients underwent two consecutive 18F-FDG PET brain scans and clinical assessments (3.7 ± 0.6 years apart). Seventeen patients also underwent 123I-MIBG and 123I-FP-CIT SPECT scans at baseline. Four subjects phenoconverted to Parkinson’s disease (PD) during follow-up. 18F-FDG PET scans were compared to controls with a voxel-wise single-subject procedure. The relationship between regional brain changes in metabolism and PD-related pattern scores (PDRP) was investigated.

Results
Individual hypometabolism t-maps revealed three scenarios: (1) normal 18F-FDG PET scans at baseline and follow-up (N = 10); (2) normal scans at baseline but occipital or occipito-parietal hypometabolism at follow-up (N = 4); (3) occipital hypometabolism at baseline and follow-up (N = 6). All patients in the last group had pathological 123I-MIBG and 123I-FP-CIT SPECT. iRBD converters (N = 4) showed occipital hypometabolism at baseline (third scenario). At the group level, hypometabolism in the frontal and occipito-parietal regions and hypermetabolism in the cerebellum and limbic regions were progressive over time. PDRP z-scores increased over time (0.54 ± 0.36 per year). PDRP expression was driven by occipital hypometabolism and cerebellar hypermetabolism.

Conclusions
Our results suggest that occipital hypometabolism at baseline in iRBD implies a short-term conversion to PD. This might help in stratification strategies for disease-modifying trials.

AbstractBackgroundCongenital anomalies are a leading cause of morbidity and mortality worldwide. We aimed to review the common surgically correctable congenital anomalies with recent updates on the global disease burden and identify the factors affecting morbidity and mortality.MethodA literature review was done to assess the burden of surgical congenital anomalies with emphasis on those that present within the first 8000 days of life. The various patterns of diseases were analyzed in both low‐ and middle‐income countries (LMIC) and high‐income countries (HIC).ResultsSurgical problems such as digestive congenital anomalies, congenital heart disease and neural tube defects are now seen more frequently. The burden of disease weighs more heavily on LMIC. Cleft lip and palate has gained attention and appropriate treatment within many countries, and its care has been strengthened by global surgical partnerships. Antenatal scans and timely diagnosis are important factors affecting morbidity and mortality. The frequency of pregnancy termination following prenatal diagnosis of a congenital anomaly is lower in many LMIC than in HIC.ConclusionCongenital heart disease and neural tube defects are the most common congenital surgical diseases; however, easily treatable gastrointestinal anomalies are underdiagnosed due to the invisible nature of the condition. Current healthcare systems in most LMICs are still unprepared to tackle the burden of disease caused by congenital anomalies. Increased investment in surgical services is needed.

Abstract
Aims
The CHA2DS2-VASc score is fundamental to stroke risk assessment in atrial fibrillation. However, stroke-related risk factors can be modified later in life. This study aimed to assess the association of changes in CHA2DS2-VASc score over time (Delta CHA2DS2-VASc score) with the risk of ischemic stroke.

Materials and methods
This is an observational analysis of 1127 atrial fibrillation patients previously enrolled in the MISOAC-AF trial. After a median 2.6-year follow-up period, baseline and follow-up CHA2DS2-VASc scores were used to extract the Delta CHA2DS2-VASc score. The stroke predicting accuracies of the baseline, follow-up, and Delta CHA2DS2-VASc scores were assessed through regression analyses.

Results
The mean baseline, follow-up, and Delta CHA2DS2-VASc scores were 4.2, 4.8, and 0.6 respectively. Ischemic stroke occurred in 54 (4.4%) patients, of which 83.3% had a Delta CHA2DS2-VASc score ≥1, contrary to 40.1% of the stroke-free group. The stroke risk per 1-point increase of the CHA2DS2-VASc score was not significantly associated with the baseline score (aHR=1.14; 95%CI: 0.93-1.41; p=0.201), whereas a significant association was observed with the follow-up (aHR=2.58; 95% CI: 2.07-3.21; p<0.001) and Delta (aHR=4.56; 95%CI: 3.50-5.94; p<0.001) scores. C-index assessment indicated that follow-up and Delta CHA2DS2-VASc scores were more potent predictors of ischemic stroke compared to baseline.

Conclusion
In atrial fibrillation patients, changes in CHA2DS2-VASc score over time were associated with the incidence of stroke. The improved predictability of follow-up and Delta CHA2DS2-VASc scores indicates that stroke risk is not a static parameter.

An Improved Bound for the Linear Arboricity Conjecture

AbstractIn 1980, Akiyama, Exoo and Harary posited the Linear Arboricity Conjecture which states that any graph G of maximum degree $$\Delta $$
Δ
can be decomposed into at most "Equation missing" linear forests. (A forest is linear if all of its components are paths.) In 1988, Alon proved the conjecture holds asymptotically. The current best bound is due to Ferber, Fox and Jain from 2020 who showed that $$\frac{\Delta }{2}+ O(\Delta ^{0.661})$$

is large enough. Moreover, our result also holds in the more general list setting, where edges have (possibly different) sets of permissible linear forests. Thus our bound also holds for the List Linear Arboricity Conjecture which was only recently shown to hold asymptotically by Kim and the second author. Indeed, our proof method ties together the Linear Arboricity Conjecture and the well-known List Colouring Conjecture; consequently, our error term for the Linear Arboricity Conjecture matches the best known error-term for the List Colouring Conjecture due to Molloy and Reed from 2000. This follows as we make two copies of every colour and then seek a proper edge colouring where we avoid bicoloured cycles between a colour and its copy; we achieve this via a clever modification of the nibble method.

AbstractTwo members of the family Betaflexiviridae associated with yam (Dioscorea spp.) have been described so far: yam latent virus (YLV) and yam virus Y (YVY). However, their geographical distribution and molecular diversity remain poorly documented. Using a nested RT-PCR assay, we detected YVY in D. alata, D. bulbifera, D. cayenensis, D. rotundata, and D. trifida in Guadeloupe, and in D. rotundata in Côte d'Ivoire, thus extending the known host range of this virus and geographical distribution. Using amplicon sequencing, we determined that the molecular diversity of YVY in the yam samples analyzed in this work ranged between 0.0 and 29.1% and that this diversity is partially geographically structured. We also identified three isolates of banana mild mosaic virus (BanMMV) infecting D. alata in Guadeloupe, providing the first evidence for BanMMV infection in yam.
