Authors: Mahata Asim , Pal Sanjib Kumar , Ohshima Hiroyuki , Gopmandal Partha P. 
Published: September 2024

AbstractThis article deals with the electrophoresis of hydrophobic colloids absorbed by a layer of polymers with an exponential distribution of the polymer segments. The functional groups present in the polymer layer further follow the exponential distribution. We made an extensive mathematical study of the electrophoresis of such core‐shell structured soft particles considering the combined impact of heterogeneity in polymer segment distribution, ion steric effect, and hydrodynamic slippage of the inner core. The mathematical model is based on the flat‐plate formalism and deduced numerical results for electrophoretic mobility are valid for weak to highly charged particles for which the particle size well exceeds the Debye‐layer thickness. In addition, we have derived closed form analytical results for electrophoretic mobility of the particle under several electrohydrodynamic limits. We have further illustrated the results for electrophoretic mobility considering a charged and hydrophobic inner core coated with an uncharged polymer layer or a polymer layer that entraps either positive or negatively charged functional groups. The impact of pertinent parameters on the overall electrophoretic motion is further illustrated.
Theoretical model of ultimate shear capacity and flexural capacity design method of boundary elements for reinforced concrete frames with steel plate shear walls

Published: September 2024

AbstractThe steel plate shear walls (SPSWs) have been proven effective in reinforced concrete frames (RCFs) as a lateral force‐resistant structure. Despite of advancements, accurately predicting the ultimate shear capacity of RCFs with SPSWs remains challenging using current simplified models. Additionally, the flexural capacity design procedure for the boundary elements (beams and columns) in previous studies of RCF‐SPSWs involved intricate iterative procedures, hindering its widespread implementation. To address the two issues, this paper investigates the pushover responses and the plate‐frame interaction (PFI) of an RCF‐SPSWs system using theoretical and numerical methods. There are three main contributions. First, a theoretical model of ultimate shear capacity for RCF‐SPSWs is proposed, which can also be used to predict shear contributions of boundary frames in RCF‐SPSWs. Calculation errors for ultimate shear capacity of RCF‐SPSWs and shear contribution from the boundary frame are only 3.7% and 6.7% respectively, which are reduced dramatically compared with the traditional model. A simplified schematic diagram for the global collapse mechanism (uniform distribution of plastic hinges within a structure) of RCF‐SPSWs is developed to facilitate the calculation of internal work and reaction forces. Secondly, a flexural capacity design method for the boundary elements to avoid in‐span plastic hinges is proposed. The proposed method enables the achievement of direct estimation of the flexural demands that could trigger a global collapse mechanism, all without intricate iterative procedures. The applicability of current assumptions for the design of steel boundary frame in RCF‐SPSWs system is discussed, and engineering suggestions are provided to ensure safer and more economic designs. Comparison results confirmed the applicability of the proposed design method, which can be adopted to achieve the global collapse mechanism for RCF‐SPSW system. Thirdly, impacts of yielding panel actions on the flexural capacity of boundary elements of RCF‐SPSWs are clarified. Comparison results demonstrated that adding SPSWs to an RCF alters the axial force on boundary elements and significantly impacts the flexural capacity. A design suggestion is made to emphasize the importance of avoiding the balanced failure of boundary elements. The proposed theoretical model can be used to economize the cross‐section of boundary elements in RCF‐SPSWs system under seismic loads due to accurate prediction of their shear contribution; the proposed flexural capacity design method can achieve a global collapse mechanism, and thus the structural safety and energy dissipation capacity are improved; moreover, the building design efficiency is also improved due to avoidance of intricate iterative procedures.

AbstractThe biomethane potential of insect frass and leachates from waste (larvae feedstock) stockpile was evaluated. Frass was derived from a black soldier fly larvae (BSFL) operation that uses a fruit and vegetable waste diet. The two waste streams were characterized and the results of their compositional, proximate, and ultimate analysis were used in estimating methane yields from these materials. The estimated biomethane potential (BMP) of the frass ranged 149–275 L/kgVS depending on the calculation method used. This result compares well with that of empirical studies for cow manure whose BMP ranges 110–275 L/kgVS. Cow manure is the most popular biogas feedstock globally. Leachates reported an estimated BMP of 150 L/kgCOD. We conclude that it may be technically feasible to produce biogas from BSFL frass and from fruit and vegetable waste leachates. However, standard BMP experiments and semicontinuous pilot studies are still necessary before commercialization of these findings. These extra tests are executed to validate these findings and ascertain the life cycle attribute and long‐term process stability and hence determine the economics of using these potential substrates for biogas production as a strategy to implementing circularity in the fruit and vegetable industry.
Delay sensitive and energy adaptive clustering hierarchy protocol using enhanced agglomerative hierarchy algorithm with time‐controlled jellyfish optimization
Authors: Agnihotri Atul Kumar , Awasthi Vishal 
Published: September 2024

AbstractWireless sensor networks have sensing functions which made up of small sensor nodes that are processing and communication capabilities. However, the traditional approach of designating a single sensor node as the cluster head often leads to a faster depletion of its energy resources than another node. So, periodic reassignment of the cluster head role among different sensor nodes is crucial to extend operational lifetime and ensure sustained performance. Therefore, this research proposes an Enhanced Agglomerative Hierarchy Algorithm based on the Low Energy Adaptive Clustering Hierarchy (EAHALEACH) protocol, coupled with an enhanced time‐controlled optimization algorithm, to enhance energy efficiency by selecting the optimal cluster head from a candidate pool. The proposed method enhances energy efficiency by optimally selecting cluster heads, which reduces energy consumption and extends the lifespan of the network. Additionally, a lightweight energy‐aware cluster head rotation algorithm is introduced to efficiently rotate the cluster head role within the sensor node network, minimizing unnecessary data transmissions and extending the network lifetime. A hybrid approach combining Carrier Sense and Time Division Multiple Access (CSTDMA) optimizes packet forwarding by dynamically allocating time slots, reducing collisions and contention to improve packet forwarding efficiency. Comparative analysis with existing techniques demonstrates that the hybrid clustering‐based LEACH protocol achieves superior performance in terms of throughput 4600 bps by 2000 rounds, energy consumption 50 J, latency as 1 ms and network lifetime in 1000th node attains 3500 s. These advancements contribute to prolonged operational efficiency and sustained performance in wireless sensor network deployments.

AbstractBackground and AimsJapan is one of the oldest societies worldwide and manages a system of care for older adults in the community. In the 2000s, a community‐based integrated care system was introduced to enable older adults to live in their neighborhoods. Home visiting nursing (HVN) is a crucial component of this system; however, the current and future shortage of home visiting nurses is a concern. Thus, HVN services may not be available in some areas; however, no indicators of the accessibility of HVN services have been developed. Developing accessibility indicators will serve as a standard for considering the allocation of health care resources and supporting future nursing policies that improve regional disparities.MethodsWe estimated the population‐weighted spatial accessibility index (PWSAI) of HVN services in Hokkaido, using the two‐step floating catchment area method (2SFCA). The 2SFCA comprised population, location of HVN agencies, number of home visiting nurses, and travel time. A multivariate regression model was run for the number of HVN users in each municipality as the objective variable to test the validity of the PWSAI; the number of home care support clinics, home care support hospitals, HVN agencies, home visiting nurses, home visiting nurses (24/7), total beds in health care facilities for older adults, and nursing homes for older adults were included as other explanatory variables.ResultsThe PWSAI was median 9.0 [interquartile range: 6.2−11.8]. The distribution of the PWSAI was mapped to visualize the existence of regional differences. As a result of the conditional autoregressive model, PWSAI and home visiting nurses (24/7) were significant, Exp(β) and 95% credible interval were 1.043 [1.015−1.076] and 1.021 [1.006−1.036], respectively.ConclusionThe PWSAI was positively correlated with the number of HVN users in each municipality and can serve as an indicator for assessing the accessibility of HVN.

AbstractAbdominal wall scar endometriosis (AWE) is a rare endometriosis that usually occurs after gynecological or obstetric surgery and for which surgical resection is the standard treatment. For large tissue defects after resection, abdominal wall reconstruction is needed. Here, we describe a mesh bridging technique using biological and polypropylene meshes for abdominal wall reconstruction. A 34‐year‐old woman visited the center with complaints of low abdominal wall pain during menstruation for more than 5 years. Her surgical history included undergoing a cesarean section delivery twice. A mass measuring 6 cm × 5 cm × 3 cm was found above the symphysis pubis in the lower part of the abdominal incision. Endometriosis lesion was considered based on abdominal ultrasound and magnetic resonance imaging findings. After a multidisciplinary discussion that included surgical experts and gynecologists, the decision was made to perform abdominal endometrial focus excision plus abdominal wall reconstruction. Two kinds of mesh were skillfully used in the operation of this patient. Biological mesh was used close to the peritoneal side and covered with polypropylene mesh to reduce the stimulation by the polypropylene mesh of the peritoneum, enhance the strength of the biological mesh, and reduce the incidence of abdominal wall hernia. Our case demonstrates that accurate diagnosis of AWE followed by complete resection and reconstruction of the abdominal wall using a combination of biological and polypropylene mesh bridging can achieve good therapeutic results and patient satisfaction.

AbstractThis study compared the safety and pharmacokinetics of a single oral dose of onradivir, an inhibitor of polymerase basic protein 2 in influenza A virus, in patients with hepatic impairment and healthy participants with normal hepatic function. Eight participants with mild hepatic impairment (Child‐Pugh A), eight participants with moderate hepatic impairment (Child‐Pugh B), and eight healthy matched controls were enrolled in this open‐label, parallel‐group clinical trial. After the administration of 600 mg of onradivir, pharmacokinetic parameters were calculated for each cohort and compared. Onradivir was generally well tolerated by all participants. No serious adverse events (AEs) and no deaths were reported during the study. Six patients with moderate hepatic impairment and three patients with mild hepatic impairment reported AEs, all of which were mild and quickly resolved. Compared with the normal liver function group, the maximum concentration, area under the curve from time zero to the last measurable concentration, and area under the curve from time zero to infinity were 103%, 68.5%, and 69.2% higher, respectively, in the mild hepatic impairment group. In the moderate hepatic impairment group, these increases were 101%, 197%, and 204%, respectively. Overall, there were clinically relevant differences in onradivir exposure between patients with mild or moderate hepatic impairment and normal controls. These data imply that onradivir dose adjustment is warranted in patients with mild or moderate hepatic impairment. The trial is registered at ClinicalTrials.gov (CT.gov identifier: NCT05856513).

However it is often difficult to obtain satisfactory pathological sections for pulmonary venous abnormalities and Ebstein anomaly.
Ultrasound is helpful to diagnose and identify aggressive angiomyxoma: A case report
Authors: Wan Min , Luo Hong 
Published: September 2024

AbstractAggressive angiomyxoma (AAM) is a rare kind of neoplasm derived from mesenchyma, which is easily confused with other superficial masses. Here, we present a 21‐year‐old young female with a 2‐year history of a mass in the right vulva. The patient's laboratory analysis yielded unremarkable results. Ultrasound examination revealed the presence of a heterogeneous solid mass in the right vulva with blood flow. Enhanced computed tomography imagines showed a capsular neoplasm in the posterior the perineal region without obvious enhancement. The patient received surgery. Biopsy after surgery revealed that the tumor was AAM. The patient was followed up regularly. In this article, we will describe sonographic and computed tomography imagines, histologic features of AAM, and review the related literature.

AbstractSustainable growth in livestock production requires reductions in trace gas emissions on grazing lands. Urine excreta patches are hot spots for accelerated emissions of carbon and nitrogen. Ruminant dietary supplementation with the isoflavone biochanin A (BCA) has been shown to improve cattle weight gain. To determine if BCA supplementation affects urine N excretion and soil trace gas emissions, soil in microcosms was amended with urine from lambs fed 0, 0.45, or 0.90 g BCA day−1. Soil gas emissions were measured over 60 days and analyzed with a linear mixed‐effects model with repeated measures. On 2 days during the incubation, BCA addition across doses significantly reduced nitrous oxide emissions by 73% and methane by 98% compared to urine from non‐dosed lambs. Cumulative ammonia volatilization was significantly reduced by 33% but cumulative nitrous oxide and methane emissions were not. Alterations in trace gas emissions occurred despite no change in urine N content with BCA feed supplementation. A separate laboratory incubation using urine from a non‐supplemented lamb that was exogenously spiked with varying BCA concentrations supported these results: BCA significantly altered ammonia and methane emission dynamics and reduced cumulative nitrous oxide emissions by up to 41%. BCA did not change soil microbial community structure, suggesting alterations to other processes, such as soil enzyme activity, were affecting soil trace gas emissions. Overall, lamb BCA supplementation did not affect urine N but reduced ammonia volatilization, which may contribute to greater sustainability in livestock production systems.

Published: September 2024

AbstractThe majority of patients undergoing exome or genome sequencing receive a nondiagnostic result. Periodic reanalysis is known to increase diagnostic yield from exome sequencing, yet laboratory reanalysis practices are obscure. We sought to define the landscape of exome and genome reanalysis across clinical laboratories. Genetic testing registries were queried to identify eligible clinical genetic laboratories offering exome and/or genome sequencing in the United States. A survey administered to lab representatives investigated reanalysis offerings, policies, perceived uptake, bioinformatic steps, and billing options. The analysis consisted of descriptive statistics. Survey data were collected from 30 of 32 eligible laboratories (93%), comprising 28 exome products and 13 genome products. Reanalysis was widely available for both exomes (n = 27/28, 96%) and genomes (n = 12/13, 92%). Most participating laboratories required ordering providers to initiate reanalysis (n = 24/28, 86%). Most respondents estimated providers initiated reanalysis in less than 10% of all exomes (n = 12/22) or genomes (n = 6/9) sequenced. The approach to reanalysis varied greatly by laboratory. Laboratory approaches to exome and genome reanalysis are highly variable and typically require provider initiation. This could contribute to low reanalysis uptake and increased administrative burden on providers. Further work should emphasize development of clinical exome and genome reanalysis standards.
Compatible powers of Hamilton cycles in dense graphs

AbstractThe notion of incompatibility system was first proposed by Krivelevich, Lee and Sudakov to formulate the robustness of Hamiltonicity of Dirac graphs. Given a graph , an incompatibility system over is a family such that for every , is a family of edge pairs with . Moreover, for an integer , we say is ‐bounded if for every vertex and its incident edge , there are at most pairs in containing . Krivelevich, Lee and Sudakov proved that there is an universal constant such that for every Dirac graph and every ‐bounded incompatibility system over , there exists a Hamilton cycle where every pair of adjacent edges of satisfies for . This resolves a conjecture posed by Häggkvist in 1988 and such a Hamilton cycle is called compatible (with respect to ). We study high powers of Hamilton cycles in this context and show that for every and , there exists a constant such that for sufficiently large and every ‐bounded incompatibility system over an ‐vertex graph with , there exists a compatible th power of a Hamilton cycle in . Moreover, we give a ‐bounded construction which has minimum degree and contains no compatible th power of a Hamilton cycle.
Can we define global collective action problems away?
Authors: Hagen Rune Jansen 
Published: September 2024

AbstractThe adoption of the Sustainable Development Goals has rejuvenated an old debate: Can foreign aid be used to finance global public goods (GPGs)? There are those who see aid exclusively as a source of development funding for poor countries. And there are others who are open to answering the question in the affirmative. I put forward five arguments why the latter position is reasonable. Firstly, the formal definition of official development assistance (ODA) cannot be said to exclude its use in financing GPGs as these goods by definition benefit developing countries. Secondly, the amount of ODA provided has never been the gold standard of rich country effort envisaged by some. In particular, the level is boosted by the self‐interests of donors. Thirdly, there is ample precedent for following the benefit principle when it comes to multilateral organisations, which are often seen as GPGs. Fourthly, distinguishing between national public goods and GPGs is not always straightforward as the former are in many cases inputs into the production of the latter, and in such cases, the dividing line between ‘traditional aid’ and ‘funding for GPGs’ is blurred. Finally, it is not obvious in practice that aid as country finance always generates greater welfare gains for developing countries than the provision of GPGs. In sum, being overly normative with respect to what ODA is distracts us from the real problem, namely, that collective action problems result in too little spending on all international public goods, including poverty alleviation in poor countries.
