The current study employs the Nikiforov-Uvarov method to solve the Schrödinger equation for quarkonium systems, utilizing the radial scalar power potential. The eigenvalues of energy and their corresponding wave functions are determined by including the spin–spin, spin–orbit, and tensor interactions in the radial scalar power potential. The mass spectra of charmonia, bottomonia, and bottom-charm in their S, P, D, and F states were determined. Our theoretical states for quarkonium systems align with experimental data across a range of spin levels, as evidenced by our comparison. The total percentage error of our work was computed, yielding a high level of accuracy. The cumulative percentage error for the meson masses of charmonia and bottomonia was determined to be 0.324% and 0.333%, respectively. The masses of the bottom-charm mesons had a total percentage error of 0.012%. Consequently, the present potential yields favorable outcomes for the quarkonium masses, surpassing previous theoretical studies and aligning well with experimental data. [ABSTRACT FROM AUTHOR]

Background: Despite numerous genetic studies on Infectious Bronchitis Virus (IBV), many strains from the Middle East remain misclassified or unclassified. Genotype 1 (GI-1) is found globally, while genotype 23 (GI-23) has emerged as the predominant genotype in the Middle East region, evolving continuously through inter- and intra-genotypic recombination. The GI-23 genotype is now enzootic in Europe and Asia. Methods: Over a 24-month period from May 2022 to June 2024, 360 samples were collected from 19 layer and 3 broiler poultry farms in central Saudi Arabia. The chickens exhibited reduced laying rates and symptoms such as weakness and respiratory distress, while broilers showed respiratory issues. Samples, including tracheal swabs and various tissue specimens, were pooled, homogenized, and stored at -20 °C prior to PCR analysis. The samples underwent virus isolation in embryonated chicken eggs, RNA extraction using automated systems, and detection of IBV through real-time RT-PCR targeting a conserved 5'-UTR fragment. Full-length genome sequencing was performed, and recombination analysis was conducted using RDP 4.6. Results: Saudi IBV strains were found to cluster into genotypes GI-1 and GI-23.1. The study identified critical amino acid substitutions in the hypervariable regions of the spike protein and detected recombination events in the ORF1ab, N, M, 3ab, and 5ab genes, with nsp3 of the ORF1ab showing the greatest number of recombination events. Conclusion: The multiple inter- and intra-genotypic recombination events that were detected in different genes indicate that the circulating IBV strains do not share a single ancestor but have emerged through successive recombination events.

Introduction: Remote ischaemic conditioning (RIC) refers to the use of controlled transient ischemic and reperfusion cycles, commonly of the upper or lower limb, to mitigate cellular damage from ischaemic injury. Preclinical studies demonstrate that RIC may have a neuroprotective effect and therefore could represent a novel therapeutic option in the management of neurological disorders. The aim of this review is to comprehensively describe the current clinical evidence of RIC in neurological disorders. Methods: A computerised search of EMBASE and OVID MEDLINE was conducted from 2002 to October 2023 for randomised controlled trials (RCTs) investigating RIC in neurological diseases. Results: A total of 46 different RCTs in 12 different neurological disorders (n = 7544) were included in the analysis. Conditions included acute ischaemic stroke, symptomatic intracranial stenosis and vascular cognitive impairment. The most commonly used RIC protocol parameters in the selected studies were as follows: cuff pressure at 200 mmHg (27 trials), 5-min cycle length (42 trials), 5 cycles of ischaemia and reperfusion (24 trials) and the application to the upper limb unilaterally (23 trials). Conclusions: The comprehensive analysis of the included studies reveals promising results regarding the safety and therapeutic effect of RIC as an option for managing neurological diseases. Particularly, the strongest evidence supports its potential use in chronic stroke patients and vascular cognitive impairment. The neuroprotective effects of RIC, as demonstrated in preclinical studies, suggest that this therapeutic approach could extend its benefits to various other diseases affecting the nervous system. However, to establish the efficacy of RIC across different neurological disorders, further trials with larger sample sizes and more diverse patient populations are warranted. Upcoming trials are expected to provide valuable evidence that will not only confirm the efficacy of RIC in neurological disease management but also help identify the most optimal RIC regimen for specific conditions.

The generalization of strongly convex and strongly m-convex functions is presented in this paper. We began by proving the properties of a strongly modified (h , m) -convex function. The Schur inequality and the Hermite–Hadamard (H-H) inequalities are proved for the proposed class. Moreover, H-H inequalities are also proved in the context of Riemann–Liouville (R-L) integrals. Some examples and graphs are also presented in order to show the existence of this newly defined class. [ABSTRACT FROM AUTHOR]

The suprachiasmatic nucleus is the circadian pacemaker of the mammalian brain. Suprachiasmatic nucleus neurons display synchronization of their firing frequency on a circadian timescale, which is required for the pacemaker function of the suprachiasmatic nucleus. However, the mechanisms by which suprachiasmatic nucleus neurons remain synchronized in vivo are poorly understood, although synaptic communication is considered indispensable. Suprachiasmatic nucleus neurons contain the neurotransmitter GABA and express GABA receptors. This has inspired the hypothesis that GABA signalling may play a central role in network synchronization, although this remains untested in vivo. Here, using local genetic deletion, we show that disruption of GABA synaptic transmission within the suprachiasmatic nucleus of adult mice results in the eventual deterioration of physiological and behavioural rhythmicity in vivo and concomitant cellular desynchrony in vitro. These findings suggest that intercellular GABA signalling is essential for behavioural rhythmicity and cellular synchrony of the suprachiasmatic nucleus neural network. [ABSTRACT FROM AUTHOR]

Fault tolerance refers to the ability of a system to continue functioning even if some of its components fail. This concept is fundamental in several domains because reliability and continuous operation are essential in carrying out their functions. Graph embedding means mapping a graph into some other structure that preserves some of the properties or relations held by the original graph. Applications in machine learning, data mining, and network analysis make fault-tolerant embedding of graphs a crucial topic. In this paper, fault-tolerant embeddings are proposed in Archimedean tessellations. The path in the embeddings does not intersect or overlap. [ABSTRACT FROM AUTHOR]

The global surge in the electric vehicle market shows a growing commitment to sustainable transportation. However, Malaysia's progress in electric vehicle development has been slow. This article presents the challenges to electric vehicle adoption in Malaysia. The study identifies critical issues such as inadequate charging infrastructure, uneven distribution of charging stations, high costs of ownership, and low consumer awareness, acceptance, and safety. These challenges collectively impact the adoption rate of electric vehicles in the Malaysian market. The study also suggests potential solutions, such as expanding the charging infrastructure, developing cost-effective strategies, implementing fast charging with renewable integration, enforcing safety protocols and standards, and establishing a battery recycling industry. By addressing these key areas, the research highlights a feasible path to boost electric vehicle adoption in Malaysia that aligns with international trends and promotes a greener future.

Architected cellular materials and structures provide the ability to tailor mechanical and functional properties based on design topological aspects. With the progressive advancement of additive manufacturing techniques, challenges and difficulties related to fabricating complex geometries are substantially reduced. Among different architected cellular materials, two types of closed-walls cellular materials, plate-lattices and triply periodic minimal surface (TPMS)–based lattices, provide outstanding mechanical properties. Plate-lattices are well-known for high stiffness, while TPMS lattices provide higher energy absorption capabilities. Herein, the mechanical behavior of the most two promising designs of both families is investigated experimentally and using finite-element analysis (FEA), namely sheet-based diamond TPMS and simple cubic–face-centered cubic–body-centered cubic (SC-FCC-BCC) plate-lattice. Fused deposition modeling (FDM) technology is utilized to fabricate the structures with acrylonitrile butadiene styrene (ABS) at several combinations of relative densities and unit cell sizes. Under quasi-static loading, diamond structures showed higher strength and energy absorption capabilities at various relative densities compared to plate-lattices. Based on experimental results, diamond is found to be 52% stiffer than the plate-lattice at low relative densities. These variations are diminished as relative density increased. ANOVA results, provided as main effects plots, show a significant dependence of mostly all mechanical properties on the three-dimensional (3D) topological design of the samples. Both structures presented outstanding mechanical energy absorption ability, suggesting their utilization in impact loading applications. [ABSTRACT FROM AUTHOR]

Pulmonary valve dysfunction is common in congenital heart disease, often leading to interventions like right ventricular outflow tract reconstruction. Transcatheter pulmonary valve replacement (TPVR) has emerged as a successful alternative to surgery, showcasing promising outcomes for managing postoperative RVOT complications. The study aimed to compare two bioprosthetic valves—Carpentier Edwards Perimount Magna Ease surgical valve and Edwards SAPIEN 3 transcatheter valve—originally designed for aortic use but adapted for pulmonary applications. The hemodynamic characteristics of a 26-mm SAPIEN 3 and a 25-mm Magna Ease were assessed in a pulse duplicator under both pulmonary and aortic conditions. Furthermore, detailed structural analyses of the leaflets were conducted using computational simulations under these conditions. The results highlighted significant differences in the hydrodynamic and structural characteristics of these two bioprosthetic valves when exposed to pulmonary versus aortic conditions. The study enhances our understanding of the biomechanics involved in surgical and transcatheter pulmonary valve replacement. Distinct hydrodynamic and structural characteristics were observed in Edwards Perimount Magna Ease and Edwards SAPIEN 3 when exposed to aortic versus pulmonary conditions. [ABSTRACT FROM AUTHOR]

The cut method is a computational approach utilized to predict the fundamental activities of physicochemical properties of chemical networks, also called topological indices. The connection number is a new idea, that gives interesting and good results of the topological indices (TIs) and entropy measures (EMs) for structural representation of chemical compounds and networks. The physical density of chemical networks is characterized by these indices. In this paper, we determined the computational results for indices based on connection numbers for a two-dimensional lattice sheet of hydrogen-bonded boric acid. Boric acid, an inorganic compound, is not very harmful when applied to the skin or consumed. Finally, graphical and numerical comparisons of topological numbers including the number of borate hydrogen-bonded double lattice forms are also included in this study. [ABSTRACT FROM AUTHOR]

Graph theory is a crucial branch of mathematics in fields like network analysis, molecular chemistry, and computer science, where it models complex relationships and structures. Many indices are used to capture the specific nuances in these structures. In this paper, we propose a new index, the weighted asymmetry index, a graph-theoretic metric quantifying the asymmetry in a network using the distances of the vertices connected by an edge. This index measures how uneven the distances from each vertex to the rest of the graph are when considering the contribution of each edge. We show how the index can capture the intrinsic asymmetries in diverse networks and is an important tool for applications in network analysis, optimization problems, social networks, chemical graph theory, and modeling complex systems. We first identify its extreme values and describe the corresponding extremal trees. We also give explicit formulas for the weighted asymmetry index for path, star, complete bipartite, complete tripartite, generalized star, and wheel graphs. At the end, we propose some open problems.

The purpose of this work is to evaluate the impacts of flow rate on cavitation and abrasion in ogee spillways using numerical simulations. One of the most complicated and frequent problems with spillway structures is abrasion. The spillway is the most crucial and delicate component of a dam. The most effective method for analyzing this significant hydraulic event is the cavitation index. Computational Fluid Dynamic (CFD) ANSYS Fluent Software was used to build a water-Air-spillway interaction model. Five different flow rates ranging from 100 m³/s to 717 m³/s were evaluated on the simulated model. The outcomes tell that when the flowrate increases, the cavitation increases proportionally, and thus the amount of abrasion of the spillway concrete surface increases. The spillway crest was found to have the least amount of abrasion, unlike the toe and chute of the spillway, which had a higher amount of abrasion. The results also show that higher flow rates lead to increased cavitation and abrasion, with the maximum abrasion of 1.0 mm occurring at the highest flow rate. [ABSTRACT FROM AUTHOR]

PPHN is a common cause of neonatal respiratory failure and is still a serious condition that is associated with high mortality. Objectives: To analyze the clinical characteristics and outcomes of SARS-CoV-2 infection in neonates with PPHN to identify neonatal cases at risk to develop severe illness. Methods: For this systematic review, we adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and searched Medline, Embase, CINAHL, and PubMed for studies on the development of COVID-19 in neonates with PPHN, published from 1 December 2019 to 29 February 2024, with an English language restriction. Results: Of the 2406 papers that were identified, 21 articles were included in the systematic review. Studies involving thirty-six neonates with PPHN and infected with SARS-CoV-2 were analyzed (twenty-nine survived, six died, and one is still hospitalized). The main causes of PPHN in neonates who had COVID-19 were neonatal respiratory distress syndrome (NRDS) (41.7%), meconium-stained amniotic fluid (MSAF) (16.7%), preterm premature rupture of membranes (PPROM) (11.1%), hypoxic ischemic encephalopathy (HIE) (5.5%), pneumonia (5.5%), and idiopathic (2.8%). Most of those neonates were male (33.3%), belonged to Indian ethnicity (50%), and were delivered via caesarean section (44.4%). COVID-19 in cases with PPHN commonly occurred in neonates born with a pregnancy range from 32 to <37 weeks (moderate to late preterm) (36.1%). The maternal severity of COVID-19 was reported to be severe in three cases only (8.3%); however, SARS-CoV-2 infection in neonates with PPHN was either severe (44.4%) or critical (22.2%). Most of these neonates experienced acute respiratory distress syndrome (ARDS) (58.3%). Early and late multisystem inflammatory syndrome in neonates (MIS-N) were reported in 50% and 11.1%, respectively. A high proportion of neonates were admitted to the intensive care unit (ICU) (58.3%) or needed mechanical ventilation (MV) (47.2%). Neonates with concurrent PPHN and SARS-CoV-2 infection who died had worse severity of COVID-19 [i.e., severity of COVID-19 was critical in 10% (neonates with PPHN who survived group) vs. 83.3% (neonates with PPHN who died group); p = 0.026]. Neonates with PPHN and COVID-19 had a higher relative risk of death if they received more antibiotics (RR 4.14, 95% CI 0.64–6.88) and if their COVID-19 was defined as critical (RR 2.84, 95% CI 0.86–9.39). Male neonates with PPHN and COVID-19 (RR 2.60, 95% CI 0.30–1.17) and those requiring prolonged invasive positive pressure ventilation (RR 2.22, 95% CI 0.64–7.73) also showed an increased relative risk for death. Conclusions: COVID-19 in neonates with PPHN is challenging and may be associated with increased mortality, severity, ICU admission, ARDS, MIS-N, and MV usage. The results should be interpreted with caution owing to the small number of studies and substantial heterogeneity and indicate a need for future research in this area. Due to its benefits, testing for SARS-CoV-2 should be encouraged for newborns with symptoms consistent with COVID-19, especially in neonates with a history of SARS-CoV-2 exposure. Effective protection measures should be implemented during delivery and post-delivery care as necessary. [ABSTRACT FROM AUTHOR]

Reticular materials are one of the more promising tools that humankind has developed to address the required energy transition. Despite their great potential showcased in the last decade, their use is so far mainly confined to the laboratory bench due to drawbacks derived from their powdery morphology. Unlike zeolites and activated carbons, the challenges in shaping and densification of reticular materials hamper their full implementation in the industry. Hence, strategies for shaping and integrating these materials need to be prioritized. Most of the existing strategies rely on applying mechanical pressure and adding chemical binders, but these approaches, although useful for shaping, diminish their final adsorption capacities and do not bring their theoretical, predicted performance. On the other hand, obtaining self‐shaped, dense bodies—so‐called monoliths—arises as a very promising and scalable alternative. Sol–gel monoliths are still scarce in the scientific literature despite their outstanding performance, particularly in terms of volumetric adsorption capacity. This review intends to help expand this scope by offering a rational guide on the self‐shaping of dense monoliths for reticular materials, as well as a complete revision of the state‐of‐the‐art in the field.

The slab is more petite and space-efficient in flat plate buildings since it is supported directly by columns rather than beams or drop panels, allowing additional floors to be added. Despite these benefits, a flat plate slab is vulnerable to brittle punching shear, a catastrophic collapse caused by the abrupt propulsion of a slab piece out from underneath by a column. In this study, Finite Element Analysis (FEA) was provided and carried out in ABAQUS/CAE 2019 to model the effects of punching shear impact on a flat plate reinforced with horizontal steel bars that vary in position, diameter, and number. Concrete was represented in the model by 8-noded hexahedral 3D brick elements and steel reinforcements by 2-noded linear 2D beam elements. The model has been modified according to the results of the experiments. In order to determine how different quantities and sizes of horizontal steel bars placed at different locations in a flat plate affected the slab's performance, parametric analysis was conducted. According to the outcomes, the shear capacity increases between 0.37 and 9.85% as the diameter of bars increases, between 1.2 and 22.9% as the quantity of bars increases, and between 1.99 and 26.1% as the bars shift from the tension side to the compression side.

The concept of being uniform strong interval-valued intuitionistic fuzzy (also termed as USIVIF) is an integration of two ideologies, which are called "uniformity" and "strong interval-valued intuitionistic fuzzy sets". Inspired by the study on uniform fuzzy topological indices, it is natural to introduce uniform IVIFTIs. Originally, topological indices were generalized for the fuzzy sets However, the utilization of the interval-valued intuitionistic fuzzy topological indices provides a finer approach, especially if there are multiple uncertainties based on intervals. Consequently, both theories imply that topological indices are not fixed and depend on certain situations or problems in the question. In this article, the generalized results for the uniform degree of the fuzzy sets associated with individual vertices/edges of strong interval-valued intuitionistic fuzzy graphs were presented and results for the total uniform degree of such graphs were also included. In addition, the nature of the implemented methods and models was discussed based on the cellular neural interval-valued intuitionistic fuzzy graphs of sets of membership and non-membership values.

The presence of oil-contaminated water due to oil spill disasters or improper industrial waste dumping is now a worldwide danger to both human health and the sustainability of the environment.The use of superhydrophobic materials has attracted considerable attention in the field of oil-water separation, owing to the increasing demand for effective and economical oil-water separation techniques.A new, easy, and inexpensive flame treatment method was used to make a nanocomposite (CuO-SiO2) in order to improve its hierarchical structure (micro-nano).The anodisation process produced copper oxide (CuO) nanostructures (NSs) on a copper mesh. Subsequently, the nanostructures were modified by dip coating with a solution of room-temperature vulcanised silicone rubber (RTV-SR).The coated mesh demonstrated remarkable characteristics of superhydrophobicity and superoleophilicity, with a water contact angle (WCA) of (160 ± 1°) and an oil contact angle (OCA) of (0°), as determined during the measurement of the surface's wetability. The coated mesh surface was characterised using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and energy dispersive spectroscopy (EDS).The successful separation of kerosene-water and diesel oil-water mixtures is accomplished by using a coated mesh in a simple filtration procedure. Furthermore, it has the capability to separate oils with a high efficiency of (99.8%) for kerosene and (87%) for diesel oil. It also has flux values of (7352.9 L.m-2.h-1) for kerosene and (6112.9 L/m2.h) for diesel. [ABSTRACT FROM AUTHOR]

We explore the linear stability of a two-dimensional flow induced due to streamwise linear shrinking of a flat surface. Dual solutions for mean flow are computed using MATLAB. A high-precision spectral numerical method is employed for the solution of the stability problem. By inspecting the neutral curves and conducting the energy analysis, it is shown that flows corresponding to both solutions are susceptible to linear instability triggered by Tollmien–Schlichting waves, particularly at large Reynolds numbers. However, the flow corresponding to the first solution achieves instability at higher Reynolds numbers in comparison to the flow corresponding to the second solution. The study shows that suction stabilizes the flow corresponding to the first solution. However, a reverse trend is observed for the flow corresponding to the second solution. These results are further corroborated through the energy analysis. An elevation in growth rates is observed by increasing suction for the second solution. In contrast, growth rates for the first solution diminish upon elevating suction. [ABSTRACT FROM AUTHOR]

The use of graph theory is prevalent in the field of network design, whereby it finds utility in several domains such as the development of integrated circuits, communication networks, and transportation systems. The comprehension of partition dimensions may facilitate the enhancement of network designs in terms of efficiency and reliability. Let V(G) be a vertex set of a connected graph and S ⊂ V(G), the distance between a vertex v and subset S is defined as d(v, S) = min{d(v, x)|x ∈ S}. An k‐ordered partition of V(G) is Rp=Rp1,Rp2,...,Rpk and the identification code of vertex v with respect to Rp is the k‐tuple rvRp=dv,Rp1,dv,Rp2,...,dv,Rpk. The k‐partition Rp is said to be a partition resolving if r(v|Rp), ∀v ∈ V(G) are distinct. Partition dimension is the minimum number k in the partition resolving set, symbolized by pd(G). In this paper, we considered the families of graph named as Toeplitz network, and proved that the partition dimension of Tn〈t1, t2〉, where t1 = 2, 3, and gcd(t1, t2) = 1 is constant.

In order to assess the quality of senior tourism services in vacation destinations, we examine complex interval valued intuitionistic Fuzzy Dombi Hamy Mean (CIVIFDHM) operators. These operators successfully manage imprecision and uncertainty in the preferences of senior tourists. However, the Hamy mean (HM) operator can identify the connections between various input data sets and produce excellent outcomes when combining and evaluating information. We illustrate their usefulness and efficacy through a case study, providing a strong instrument for improving service quality for senior citizens and promoting an inclusive and fulfilling travel experience. In this work, we develop the HM operator and Dombi operations with Complex interval valued intuitionistic fuzzy numbers (CIVIFNs). We recommend the CIVIFDHM operator, complex interval valued intuitionistic fuzzy weighted Dombi Hamy mean (CIVIFWDHM), complex interval valued intuitionistic fuzzy dual Dombi Hamy mean (CIVIFDDHM), and complex interval valued intuitionistic fuzzy weighted dual Dombi Hamy mean (CIVIFWDD) operators. Next, multiple attribute decision making (MADM) models are constructed with the help of CIVIFWDHM and CIVIFWDDHM operators. We provided an evaluation of an older tourism operator in a tourist area as an example to show the suggested models. [ABSTRACT FROM AUTHOR]

Flat plate structures consist of a slab supported directly by columns without beams or drop panels, resulting in a thinner slab with more efficient use of space. Despite these advantages, a flat plate slab is subjected to brittle punching shear. Sudden collapse may occur when a column pushes a piece of concrete from the slab above it. This paper displays Finite Element Analysis (FEA) using ABAQUS/ CAE 2019 to simulate the punching shear impact on a flat plate strengthened with horizontal steel bars of varying number and diameter, located at the compressive side of the slab. A numerical model was constructed with 8-noded hexahedral 3D brick elements for concrete and 2-noded linear 2D beam elements for steel reinforcement. The model was adapted based on experimental data. A parametric analysis was conducted to evaluate the impact of placing horizontal steel bars at the compression side of the flat plate and changing the quantity and size of these bars on the slab's performance. The results illustrate that the shear capacity increases from 17.07% to 28.13% as the bar diameter increases and from 19.17% to 54.82% as the number of bars increases. [ABSTRACT FROM AUTHOR]

Managed pressure drilling operation is classified as an unconventional drilling method by controlling the annulus pressure between borehole and the drillstring near formation pressure. A controlling automated system choke system must change the downhole pressure in order to complete managed pressure drilling. It uses a number of tools and methods, including pressurized mud cap drilling, dual gradient, and constant bottomhole pressure, to sustain kicking and address other problems with lost circulation and differential sticking. In this case study, a deep well (16641 feet) well is documented along with the incidents, drilling sidetracks, issues, and costs. The well experienced a blowout and was temporarily sealed following a series of poorly sidetracked drilling operations. It was decided to return to the well and use managed pressure drilling (MPD) to drill a horizontal lateral sidetrack. The Austin Chalk formation, which is a fractured carbonate reservoir and exhibits high pressures, low concentrations of H2S and CO2, significant fluid losses into fractures, and well control issues while drilling sections, is the well's main target. Rig-up with the standard drilling flow path and wellbore planning process, schematic, drilling, and control parameters were involved. To better understand the appropriateness of the circumstances, project management for the drilling operation time against depth with change management and cost estimation process was discussed. This helped to lead to the selection of managed pressure drilling as the most advantageous option to deal with some unique critical conditions of oil wells and prepare an appropriate economic feasibility study.

The title compound, bis­[di­thio­bis­(formamidinium)] hexa­bromido­ruthenium dibromide trihydrate, [(NH2)2CSSC(NH2)2]2[RuBr6]Br2·3H2O, crystallizes in the ortho­rhom­bic system, space group Cmcm, Z = 4. The [RuBr6]2− anionic complex has an octahedral structure. The Ru—Br distances fall in the range 2.4779 (4)–2.4890 (4) Å. The S—S and C—S distances are 2.0282 (12) and 1.783 (2) Å, respectively. The H2O mol­ecules, Br− ions, and NH2 groups of the cation are linked by hydrogen bonds. The conformation of the cation is consolidated by intra­molecular O—H⋯Br, O—H⋯O, N—H⋯Br and N—H⋯O hydrogen bonds. The [(NH2)2CSSC(NH2)2]2+ cations form a hydrogen-bonded system involving the Br− ions and the water mol­ecules. Two Br− anions form four hydrogen bonds, each with the NH2 groups of two cations, thus linking the cations into a ring. The rings are connected by water mol­ecules, forming N—H⋯O—H⋯Br hydrogen bonds.

Survival of patients after repair of coarctation of Aorta (CoA) has improved significantly over the decades, but patients have decreased life expectancy as compared to the general population. This has been attributed to increased hypertension, cerebrovascular disease, and coronary artery disease. There has also been an increasing concern of overweight and obesity in patients with adult congenital heart disease. While there have been studies looking at the impact of long-term hypertension on myocardial performance and outcomes in this population, this study aims to assess the impact of obesity in these patients on their myocardial performance. Ventriculo-arterial coupling is used as a measure of myocardial performance which reflects the interaction between cardiac contractility and arterial elastance. Patients after CoA repair are known to have hypertension affecting the arterial elastance. Obesity affects cardiac contractility as well. This study demonstrated that in a group of young patients after CoA repair, body mass index (BMI) has a relationship with left ventricular (LV) contractility and myocardial performance. This relationship was independent of blood pressure. BMI itself was not seen to affect the determinants of diastolic function in this study, suggesting that LV contractility may be affected before one can notice a change in the diastolic function secondary to BMI.

Milk quantity and quality traits in cattle are affected by udder health, breed, genetic (such as heritability, repeatability, and heterosis), and environmental factors. The present study was designed to evaluate the effect of udder health, genetic factors and environmental factors on milk performance traits in cattle breeds. The study was conducted on four dairy farms in Khyber Pakhtunkhwa, Pakistan. A total of 291 milk samples and 547 records were collected from lactating cattle ranging between parities one to six. For milk performance traits and udder health, each milk sample was analysed for milk composition (fat %, protein %, and lactose %) and SSC (by direct microscopic SCC method). The data were analysed using a generalized linear model of SAS studio for the effect of the SCC, breed, and herd on milk performance while wombat and CFC for the analysis of genetic and non-genetic factors. The results showed that animals with higher SCC have significantly lower (P<0.01) milk fat %. Breed-wise analysis showed significantly higher (P<0.01) protein % in Achai, lactose % in Jersey and its crossbred (Jersey x Achai), and LMY was recorded significantly higher in Friesian and its crossbred Jersey x Friesian (JF). The analysis of the environmental effect on milk composition and LMY showed that animals kept in the different herds have significantly different (P<0.01) milk compositions and LMY. The estimates of additive genetic variance (Va), variance of the permanent environment (Vpe), and estimates of phenotypic variation (Vp) were recorded highest for SCC. The analysis of the effect of genetic factors (i.e. heritability, repeatability, and heterosis) revealed that estimation of heritability was highest (0.59) for age at first calving (AFC) while lowest (0.00) for calving interval (CI), and estimation of repeatability was highest (0.99) for AFC while lowest (0.00) for CI. The results of heterosis analysis showed that crossbred (Achai x Jersey) had positive heterosis for milk composition traits and SCC while negative heterosis for LMY compared to their purebreds. The study concluded that crossbred, better herd management and nutrition, and selection based on genetic factors (such as heritability, repeatability, and heterosis) can bring improvement in milk performance traits and udder health.

A new method to assess the quality of additive manufacturing (AM) metal powders using the triboelectric charging concept is demonstrated using CpTi, Ti6Al4V, AlSi10Mg, IN 738, and SS 316L powders. For each powder tested, the surface chemical composition was first analyzed using X-ray photoelectron spectroscopy (XPS) to determine the composition of the passivation layer. Some modifications to the current GranuCharge™ setup, developed by GranuTools™, were then performed by incorporating a flow rate measuring tool to assess how tribocharging is affected as a function of flow rate. Variations in the tribocharging response have been found with the flow rate of CpTi, AlSi10Mg and SS 316L powders. Moreover, results suggest that the tribocharging behavior might not be the same even with powders fabricated with the same passivation process. Finally, the compressed exponential model of Trachenko and Zaccone was used to reproduce the tribocharging behavior of the powders. The models were found to work best when the stretch constant β = 1.5, which is identical to the value found in other systems such as structural glasses, colloidal gels, entangled polymers, and supercooled liquids, which experience jamming when motion of individual particles become restricted, causing their motion to slow down.

In this paper, we have analyzed the bifurcation of stagnation points in the non-Newtonian flow of the FENE-P fluid through a channel induced by peristalsis. The stream function for the flow under consideration is developed under negligible inertia and streamline curvature effects. A nonlinear autonomous system is developed for scrutiny of the critical points. A dynamical system approach is used to examine the stability of bifurcation points. Streamline patterns, and local and global bifurcation diagrams are plotted for analysis of the backward flow, trapping, and augmented flow regions. The impacts of important embedded parameters, i.e., extensibility parameter and Deborah number on local and global bifurcation diagrams, are also examined. The whole analysis reveals that two critical conditions appear in the flow field that are actually responsible for the conversion of backward flow to trapping and trapping to augmented flow. It is further seen that bifurcations occur at lower flow rates for increasing Deborah's number while an opposite trend prevails for increasing the extensibility parameter. A comparison of bifurcations between planar and axisymmetric flows is also performed. It is observed that a greater area of the trapping region is encountered for axisymmetric flow than that for planar flow. [ABSTRACT FROM AUTHOR]

Introduction: Given the fact that health facilities are complex societies, the need for team work that involves professionals from different fields to contribute towards the best working standards for care givers is desirable. Integrated healthcare systems focus on cooperation with other pharmacy, laboratory service, radiography, social service and health administration and thus there is no gap between the different health care needed of patients. The leadership of such synergy is crucial to assist in meeting the rising need of personalized, affordable, and effective models of health care delivery. Aim of work: To explore the pivotal roles of pharmacy, laboratory services, radiography, social services, and health administration, the importance of their integration, and how their synergy enhances healthcare delivery. Methods: We conducted a comprehensive search in the MEDLINE database's electronic literature using the following search terms: Enhancing, Healthcare Systems, Synergy, Pharmacy, Laboratory, Radiography, Social Services and Health Administration. The search was restricted to publications from 2016 to 2024 in order to locate relevant content. We performed a search on Google Scholar to locate and examine academic papers that pertain to my subject matter. The selection of articles was impacted by certain criteria for inclusion. Results: The publications analyzed in this study encompassed from 2016 to 2024. The study was structured into various sections with specific headings in the discussion section. Conclusion: The synergy of pharmacy, laboratory, radiography, social service and health administrative departments is equally important for improvement of healthcare systems. All the disciplines have their own specialization and approach to integrate into effective, unified, and individualized treatment. This paper identifies obstacles to improvement across healthcare organizations and how interdisciplinary collaboration and technology can help systems gain a fuller understanding of the needs of patients and communities. As the healthcare continues to change, the combination of these domains will continue to be a foundation of quality as well as access to care for all. [ABSTRACT FROM AUTHOR]

Sunscreen formulation forms a protective layer on the skin to protect it from the harmful impact of UV radiation. The effectiveness of sunscreen is determined by the sun protection factor (SPF). The higher the SPF, the more active the product is in avoiding sunburn. Thus, it is compulsory to determine the SPF value of the products used to stop sunburn. The present study aimed to determine the ultraviolet (UV) absorption properties of alcoholic herbal extracts of peels and seeds of vegetable and fruit sources by determining the SPF number as an alternative to synthetic sunscreen using the spectrophotometric method. Alcoholic extract was prepared by dissolving the ground form of green produce (Watermelon, Orange, and Lemon seeds and peels of Banana, Lemon, and Orange), and the absorbance was recorded between 290-320 nm. A spectroscopic study revealed that all of the tested samples of vegetables and fruits in both ethanolic and methanolic extracts showed UV protection capabilities related to their high absorbance, which was satisfactory in finding their SPF values. The analysis of SPF values showed that variations were observed in both ethanolic and methanolic extracts, followed by exhibiting the highest absorbance value in normal, UV, and dark exposure. Moreover, the results after 7 days of exposure to solar radiation (UV) radiation in the ethanolic extract of green produce showed an increase in the SPF, indicating that extracts were not photosensitive in the range between 290 and 320 nm while a decrease in SPF to methanol, revealing that all samples were photosensitive in the range between 290 and 320 nm. The values of the SPF showed that peels and seeds may also be considered for the formulation of the green sunscreen cream. [ABSTRACT FROM AUTHOR]

Ovariectomy induced osteoporosis in rats is similar to oestrogen depleted postmenopausal osteoporosis in females. Osteoporosis after menopause is a serious global health issue in elderly populations that have shown minimal consideration until lately. Anti-resorptive medicines such as oestrogen, calcitonin, bisphosphonates and others are used in traditional treatments for postmenopausal osteoporosis. These have various negative effects and do not modify bone mass or replace bone that has already been lost. The goal of this study was to see if a herbal extract combination (Piper nigrum and Linum usitatissimum) might prevent ovariectomized rats from osteoporosis. 10-12 w of age female rats are randomized into 6 groups of 6 rats each. The sham operated group, the control group and four other ovariectomized groups, ovariectomized with standard (calcium carbonate 250 mg/kg); ovariectomized with black pepper extract (500 mg/kg), and ovariectomized with flaxseed extract (600 mg/kg) are treated for 14 d by oral dosing. The in silico study revealed that lignan has a direct interaction with gene interleukin-6 and an indirect connection with CYP4F2 and piperine indirectly inhibit tumor necrosis factor gene. The present study reveals that a combination of Piper nigrum and Linum usitatissimum extracts has given significant results when compared to these extracts if given alone in the estimation of various bone turnover markers alkaline phosphatase, calcium, phosphorus, total protein content and histopathology of the right leg femur bone. To summing up, Piper nigrum and Linum usitatissimum extract has a definite anti-osteoporotic activity and could be used as an analogous treatment for postmenopausal osteoporosis.

Communicating dynamic insights to a wide audience constitutes a long‐standing challenge among system dynamics modelers. We propose that telling stories is a compelling way of introducing feedback insights, as well as an understanding of how our individual decisions are linked to social behaviors in our day‐to‐day living. These decisions often involve moral and ethical trade‐offs. In this article, we use examples and heuristics to illustrate how the process of building a system dynamics model can drive a storytelling project. In a complimentary manner, the process of storytelling supports and enriches a model building project by exploring new dynamic hypotheses. © 2024 The Authors.

One of the DC-DC conversion systems is boost converters which are used in commonly with solar systems to convert low DC voltage levels to higher ones. This is particularly useful in solar systems because the voltage generated by solar panels can vary widely depending on factors such as the amount of sunlight and the temperature of the panels. The duty cycle of the boost must be controlled to have the maximum output power. Using the Grey Wolf Optimizer to control the duty cycle of a boost converter is one of the ways to have this maximum power. The optimization problem can be stated as minimizing the voltage error of the boost converter output by optimizing the duty cycle. The objective function can be defined as the difference between the desired output voltage and the actual output voltage of the boost converter. The duty cycle can be optimized by adjusting the PWM signal's pulse width that controls the boost converter switch. [ABSTRACT FROM AUTHOR]

Background: Perivascular epithelioid cell neoplasms (PEComas) encompass a heterogeneous family of mesenchymal tumors. Previously described clinicopathologic features aimed at distinguishing benign from malignant variants but lacked prognostic value. Methods: This retrospective analysis examined clinicopathologic data from patients who had localized PEComa across French Sarcoma Network centers. The authors analyzed 12 clinicopathologic features in a Cox proportional hazard framework to derive a multivariate prognostic risk model for event‐free survival (EFS). They built the PEComa prognostic score (PEC‐PRO), in which scores ranged from 0 to 5, based on the coefficients of the multivariate model. Three groups were identified: low risk (score = 0), intermediate risk (score = 1), and high risk (score ≥ 2). Results: Analyzing 87 patients who had a median 46‐month follow‐up (interquartile range, 20–74 months), the median EFS was 96.5 months (95% confidence interval [CI], 47.1 months to not applicable), with 2‐year and 5‐year EFS rates of 64.7% and 58%, respectively. The median overall survival was unreached, with 2‐year and 5‐year overall survival rates of 82.3% and 69.3%, respectively. The simplified Folpe classification did not correlate with EFS. Multivariate analysis identified three factors affecting EFS: positive surgical margins (hazard ratio [HR], 5.17; 95% CI, 1.65–16.24; p =.008), necrosis (HR, 3.94; 95% CI, 1.16–13.43; p =.030), and male sex (HR, 3.13; 95% CI, 1.19–8.27; p = 0.023). Four variables were retained in the prognostic model. Patients with low‐risk PEC‐PRO scores had a 2‐year EFS rate of 93.7% (95% CI, 83.8%–100.0%), those with intermediate‐risk PEC‐PRO scores had a 2‐year EFS rate of 67.4% (95% CI, 53.9%–80.9%), and those with high‐risk PEC‐PRO scores had a 2‐year EFS rate of 2.3% (95% CI, 0.0%–18.3%). Conclusions: The PEC‐PRO score reliably predicts the risk of postoperative recurrence in patients with localized PEComa. It has the potential to improve follow‐up strategies but requires validation in a prospective trial. By using a weighted combination of clinicopathologic features, the perivascular epithelioid cell neoplasm prognostic (PEC‐PRO) score identified three different prognostic groups, including a low risk (score = 0), an intermediate risk (score = 1), and a high risk (score ≥2) of recurrence. The PEC‐PRO score reliably predicts the recurrence risk in patients with localized perivascular epithelioid cell neoplasms and has the potential to improve follow‐up strategies and personalize adjuvant treatments.

The title compound, bis­[di­thio­bis­(formamidinium)] hexa­bromido­ruthenium dibromide trihydrate, [(NH2)2CSSC(NH2)2]2[RuBr6]Br2·3H2O, crystallizes in the ortho­rhom­bic system, space group Cmcm, Z = 4. The [RuBr6]2-anionic complex has an octa­hedral structure. The Ru--Br distances fall in the range 2.4779 (4)-2.4890 (4) Å. The S--S and C--S distances are 2.0282 (12) and 1.783 (2) Å, respectively. The H2O mol­ecules, Br- ions, and NH2 groups of the cation are linked by hydrogen bonds. The conformation of the cation is consolidated by intra­molecular O--H...Br, O--H...O, N--H...Br and N--H...O hydrogen bonds. The [(NH2)2CSSC(NH2)2]2+ cations form a hydrogen-bonded system involving the Br - ions and the water mol­ecules. Two Br - anions form four hydrogen bonds, each with the NH2 groups of two cations, thus linking the cations into a ring. The rings are connected by water mol­ecules, forming N--H...O--H...Br hydrogen bonds. [ABSTRACT FROM AUTHOR]

In the present study, the range of alpha particles in pure semiconductors have been studied to know the effect of radiation for device made from semiconductors (silicon and germanium) that used in the environmental application. The range of alpha particles was calculated by using SRIM2013 program and Astar program. The results have been observed the direct relationship between the range of alpha particles and the energy of incident particles. The range of alpha particles in both germanium and silicon in present work has shown the agreement with the results of SRIM2013 program and Astar program. The relation between the range of alpha particle and its energy is clear in all the results. [ABSTRACT FROM AUTHOR]

We construct a model to investigate HIV/AIDS dynamics in real cases and study its mathematical analysis. The study examines the qualitative outcomes and confirms the local and global asymptotic stability of both the endemic equilibrium and the disease-free equilibrium. The model's criteria for exhibiting both local and global asymptotically stable behavior are examined. We compute the endemic equilibria and obtain the existence of a unique positive endemic equilibrium. The data is fitted to the model using the idea of nonlinear least-squares fitting. Accurate parameter values are achieved by fitting the data to the model using a 95% confidence interval. The basic reproduction number is computed using parameters that have been fitted or estimated. Sensitivity analysis is performed to discover the influential parameters that impact the reproduction number and the eradication of the disease. The results show that implementing preventive measures can reduce HIV/AIDS cases. [ABSTRACT FROM AUTHOR]

A relatively recent approach in molecular graph theory for analyzing chemical networks and structures is called a modified polynomial. It emphasizes the characteristics of molecules through the use of a polynomial-based procedure and presents numerical descriptors in algebraic form. The Quantitative Structure-Property Relationship study makes use of Modified Polynomials (M-Polynomials) as a mathematical tool. M-Polynomials used to create connections between a material's various properties and its structural characteristics. In this study, we calculated several modified polynomials and gave a polynomial description of the magnesium iodide structure. Particularly, we computed first, second and modified Zagreb indices based M-polynomials. Randić index, and inverse Randić indices based M-polynomials are also computed in this work.
