A comparative analysis of RCC and composite buildings using the new plastic deformation (PD) method
Authors: Qing Zhang Qing , Na Zhang Li 
Published: March 2024

AbstractLow computational efficiency and non-linearity behaviour make the simulation of the overall building structure problematic to attain with a single dynamic or static method. Thus, this paper uses a plastic deformation (PD) method based on concrete plasticity theory (CPT) for comparative analysis of multi-storey reinforcement cement concrete (RCC) and composite buildings under common and rare earthquake loads. For this purpose, a 15-storey tall building was selected for analysis using ABAQUS software. At first, a possible building model was created and then plastic deformation analysis was performed using the new PD method under both common and rare earthquakes. After that, a nonlinear time history analysis was conducted, and the results of plastic strain distribution, lateral displacement, peak acceleration, storey stiffness, shear force, storey drift, normalised shear, and top deflection of the RCC and composite buildings were studied deeply. The fundamental time period of the RCC model was found to be 5.2 s while the fundamental time period of the composite model was 6 s. Under common and rare earthquake leads, the peak acceleration of the RCC building was 19% and 22% higher than composite buildings, respectively. Under common and rare seismic loads, the top deflections of the composite building were 33% and 36% higher than those of RCC buildings, respectively. In the case of the RCC building, it was found in this study that higher peak acceleration (PA) of the ground motion led to higher storey top displacement, storey drift, shear force and top deflection under both ground motions. Numerical results suggested that the use of composite structure is more durable than RCC structure. It was also concluded that the PD method could also be effectively used for the analysis of RCC and composite buildings under dynamic loads.

AbstractThis study presents a data-driven assisted real-time optimization model which is an innovative approach to address the challenges posed by integrating Submerged Arc Furnace (SAF) systems with renewable energy sources, specifically photovoltaic (PV) and wind power, with modern intelligent energy terminals. Specifically, the proposed method is divided into two stages. The first stage is related to data-driven prediction for addressing local time-varying renewable energy and electricity market prices with predicted information, and the second stage uses an optimization model for real-time SAF dispatch. Connections between intelligent energy terminals, demand-side devices, and load management systems are established to enhance local renewable resource utilization. Additionally, mathematical formulations of the operating resistance in SAF are explored, and deep neuron networks are employed and modified for dynamic uncertainty prediction. The proposed approach is validated through a case study involving an intelligent energy terminal with a 12.5 MVA SAF system and 12 MW capacity renewable generators in an electricity market with fluctuating prices. The findings of this research underscore the efficacy of the proposed optimization model in reducing operational costs and enhancing the utilization of localized renewable energy generation. By integrating four distinct dissatisfaction coefficients into the optimization framework, we demonstrate the model's adaptability and efficiency. The application of the optimization strategy delineated herein results in the SAF system's profitability oscillating between $111 and $416 across various time intervals, contingent upon the coefficient settings. Remarkably, an aggregate daily loss recovery amounting to $1,906.84 can be realized during the optimization period. Such outcomes not only signify considerable economic advantages but also contribute to grid stability and the diminution of renewable energy curtailment, thereby underscoring the dual benefits of economic efficiency and sustainability in energy management practices.

Published: March 2024

AbstractDynein-2 is a large multiprotein complex that powers retrograde intraflagellar transport (IFT) of cargoes within cilia/flagella, but the molecular mechanism underlying this function is still emerging. Distinctively, dynein-2 contains two identical force-generating heavy chains that interact with two different intermediate chains (WDR34 and WDR60). Here, we dissect regulation of dynein-2 function by WDR34 and WDR60 using an integrative approach including cryo-electron microscopy and CRISPR/Cas9-enabled cell biology. A 3.9 Å resolution structure shows how WDR34 and WDR60 use surprisingly different interactions to engage equivalent sites of the two heavy chains. We show that cilia can assemble in the absence of either WDR34 or WDR60 individually, but not both subunits. Dynein-2-dependent distribution of cargoes depends more strongly on WDR60, because the unique N-terminal extension of WDR60 facilitates dynein-2 targeting to cilia. Strikingly, this N-terminal extension can be transplanted onto WDR34 and retain function, suggesting it acts as a flexible tether to the IFT “trains” that assemble at the ciliary base. We discuss how use of unstructured tethers represents an emerging theme in IFT train interactions.
Morphological Complexity in Writing: Implications for Writing Quality and Patterns of Change
Authors: Wood Carla , Garcia-Salas Miguel , Schatschneider Christopher , Torres-Chavarro Michelle 
Published: March 2024

Purpose:
The current study examined (a) the relation between morphologically complex word (MCW) use (words containing at least one derivational morpheme such as prefixes and suffixes) and teachers' ratings of writing quality, (b) average change in MCW use in writing across the school year, and (c) differential change in MCW among students with varying language abilities and linguistic backgrounds including students with developmental language disorders (DLDs) and multilingual learners (MLs).

Method:
Expository writing samples (writing for the purpose of explaining or educating) were collected in October and May from 824 fifth-grade students, including 109 with DLD and 170 who were MLs receiving English as a second language service. Students' written responses were coded for the use of MCW. Pearson product–moment correlations and two-level hierarchical linear models were employed to investigate the association between MCW usage and writing quality, as well as increases in MCW usage over the course of the academic year, taking into account the nested structure of students within classrooms.

Results:

The relation between students' MCW use and teachers' writing quality ratings was moderately strong (
r
= .47). Student use of MCW in expository writing showed significant change from fall to spring across all students. However, the amount of change in MCW use across the school year was significantly lower for MLs (effect size [ES] = .09) and students identified with DLD (ES = .10).

Conclusions:
The relation between MCW use and teachers' writing quality ratings highlights the utility of MCW as a written language measure for progress monitoring or assessment. The presence of differential change and potential Matthew effects for MLs and students with DLD substantiates the need for further exploration of instructional components that support the increased use of complex vocabulary.
Fractionation in young cores: Direct determinations of nitrogen and carbon fractionation in HCN

Published: March 2024

Context. Nitrogen fractionation is a powerful tracer of the chemical evolution during star and planet formation. It requires robust determinations of the nitrogen fractionation across different evolutionary stages.
Aims. We aim to determine the 14N/15N and 12C/13C ratios for HCN in six starless and prestellar cores and to compare the results between the direct method using radiative transfer modeling and the indirect double isotope method, assuming a fixed 12C/13C ratio.
Methods. We present IRAM observations of the HCN 1–0, HCN 3–2, HC15N 1–0 and H13CN 1–0 transitions toward six embedded cores. The 14N/15N ratio was derived using both the indirect double isotope method and directly through non-local thermodynamic equilibrium (NLTE) 1D radiative transfer modeling of the HCN emission. The latter also provides the 12C/13C ratio, which we compared to the local interstellar value.
Results. The derived 14N/15N ratios using the indirect method are generally in the range of 300-550. This result could suggest an evolutionary trend in the nitrogen fractionation of HCN between starless cores and later stages of the star formation process. However, the direct method reveals lower fractionation ratios of around ~250, mainly resulting from a lower 12C/13C ratio in the range ~20–40, as compared to the local interstellar medium value of 68.
Conclusions. This study reveals a significant difference between the nitrogen fractionation ratio in HCN derived using direct and indirect methods. This can influence the interpretation of the chemical evolution and reveal the pitfalls of the indirect double isotope method for fractionation studies. However, the direct method is challenging, as it requires well-constrained source models to produce accurate results. No trend in the nitrogen fractionation of HCN between earlier and later stages of the star formation process is evident when the results of the direct method are considered.

AbstractChanges in surgical practice patterns to cure stress urinary incontinence (SUI) became evident after FDA warnings regarding vaginal mesh were issued. The primary aim was to describe
nationwide numbers of suburethral alloplastic slings (SAS) inserted in 2010, 2015, 2018 and 2021 in Germany. Secondary, numbers were related to SUI specific non-alloplastic alternatives and
bulking agents. Additionally, age distribution and overall inpatient surgeries in women were subject to analysis.Descriptive study utilizing data gathered from the German Federal Statistical Office (www.destatis.de). Included were the following procedures of
inpatient surgery: A. SAS; B. non-allplastic slings; C. open/laparoscopic colposuspension; D. Bulking agents; overall changes and changes in age distribution (groups of 5-years intervals) are
described.Overall, n = 3599466 female inpatient procedures were analyzed. There was a considerable decrease of SAS surgeries of 28.49% between 2010 (n = 23464) and 2015 (n = 16778), and a decrease
of 12.42% between 2015 and 2018 (n = 14695) and an additional decrease of 40.66% between 2018 and 2021 (n = 8720). Over time a 55.03% continuous decrease in non-alloplastic slings was observed
(n = 725 in 2010 to n = 326 in 2021). Open and laparoscopic colposuspension numbers went down with a rate of 58.23% (n = 4415 in 2010, n = 1844 in 2021). Between 2010 and 2018, only bulking
agent procedures increased with a rate of 5.89% from n = 1425 to n = 1509.There was a considerable decrease in inpatient surgical procedures using SAS. Alternatives not only failed to compensate, but experienced also a major decline.

Published: March 2024

Abstract
Background Narrative nursing notes are a valuable resource in informatics research with unique predictive signals about patient care. The open sharing of these data, however, is appropriately constrained by rigorous regulations set by the Health Insurance Portability and Accountability Act (HIPAA) for the protection of privacy. Several models have been developed and evaluated on the open-source i2b2 dataset. A focus on the generalizability of these models with respect to nursing notes remains understudied.
Objectives The study aims to understand the generalizability of pretrained transformer models and investigate the variability of personal protected health information (PHI) distribution patterns between discharge summaries and nursing notes with a goal to inform the future design for model evaluation schema.
Methods Two pretrained transformer models (RoBERTa, ClinicalBERT) fine-tuned on i2b2 2014 discharge summaries were evaluated on our data inpatient nursing notes and compared with the baseline performance. Statistical testing was deployed to assess differences in PHI distribution across discharge summaries and nursing notes.
Results RoBERTa achieved the optimal performance when tested on an external source of data, with an F1 score of 0.887 across PHI categories and 0.932 in the PHI binary task. Overall, discharge summaries contained a higher number of PHI instances and categories of PHI compared with inpatient nursing notes.
Conclusion The study investigated the applicability of two pretrained transformers on inpatient nursing notes and examined the distinctions between nursing notes and discharge summaries concerning the utilization of personal PHI. Discharge summaries presented a greater quantity of PHI instances and types when compared with narrative nursing notes, but narrative nursing notes exhibited more diversity in the types of PHI present, with some pertaining to patient's personal life. The insights obtained from the research help improve the design and selection of algorithms, as well as contribute to the development of suitable performance thresholds for PHI.

ABSTRACTWe present our expeilence of pedicled Anterolateral thigh flap for reconstruction of groin defects in cancer patients. Total of 17 flaps in 16 patients were performed between January 2001 to May 2003. 15 flaps were used for groin defects after node dissection for carcinoma of Penis (bilateral groin defects in one patient), 1 case of Squamous Cell Carcinoma of groin and 1 case of Soft Tissue Sarcoma of groin. All patients were male. 16 were myocutaneous variety and 1 was fasciocutaneous flap based on the septocutaneous perforator. Complications were few and all patients achieved durable long-term coverage. We found the flap to be technically easy and reliable.
Reliance on double pedicle TRAM flap technique in breast reconstruction based on mammographic evidence

Published: March 2024

ABSTRACTBreast reconstruction is now a part of the overall treatment of breast cancer. Its main drawback is rather the suspicion to conceal any probable recurrence. Fat necrosis is a particularly important finding because it can be mistaken for a local recurrence. Alternatively, local recurrences may be dismissed as areas of fat necrosis. Fat necrosis is a relatively minor complication of TRAM flap breast reconstruction but one that can induce anxiety, expense, and inconvenience for patients and concerns about tumor recurrence. The techniques selected for reconstruction must carry the least risks for these awful complications.15 breast cancer cases were treated in our center by using Bostwick's principles. These include double-pedicle technique in cases with one or two risk factors and added vascular delay two weeks prior to this procedure in cases with more risk factors.During the follow up period, neither the patients nor her physicians experienced any nodules in their treatment sites clinically. One case is the only exception that she felt hardness but it softened.Mammographically, no images of fat necrosis were observed in any of the cases.In contrary to other studies reporting no advantages of double pedicle technique to lessen the risk for fat necrosis, we observed fat necrosis only in one of 15 cases. This may be because both sides of the flap are supplied axially and delay procedures are added in high risk patients.

A novel nanocomposite of MXene/cadmium azide with high detonation performance

Published: March 2024

A novel MXene/cadmium azide nanocomposite with a low input energy and high output power is designed by self-assembly of Cd ions on the MXene layers and subsequent in situ azidation in a solution reaction. The research result shows that cadmium azide nanoparticles with a uniform size of ∼50 nm are well dispersed on the MXene nanosheet’s surface, which is benefited from the rich functional groups on the MXene surface that can effectively immobilize and prevent the aggregation of the nanoparticles through electrostatic interaction. The thermal decomposition temperature (378.42 °C) and crystal structure of cadmium azide show no noticeable change after hybridizing with the MXene; more positively, the required input energy of the MXene/cadmium azide nanocomposite is significantly reduced, which is verified by its electric initiation input voltage of just 4.65 V. In addition, detonation can be realized by loading a less amount of the MXene/cadmium azide nanocomposite. These results demonstrate that the MXene/cadmium azide nanocomposite has the potential to be used as detonators in high-temperature environments.
Emerging vegetable crop diseases and their management options

Published: March 2024

Abstract

Vegetable crops are economically important throughout the world and they all share some common features, such as high value, globalisation of the seed market, continuous intensification and innovation of their production systems, the presence of a high number of crops and varieties, and a limited availability of chemical pesticides for their disease management. In this review, we focus on fungal plant pathogens, although several diseases caused by bacteria are becoming important. Many diseases caused by soilborne pathogens, such as
Fusarium oxysporum
(different
formae speciales
),
Sclerotinia sclerotiorum
,
Rhizoctonia solani, Pythium
spp. and
Phytophthora
spp., become more severe over the last few years. Many of these diseases can be considered the consequence of the profound changes that soil disinfestation has undergone since the use of methyl bromide was prohibited in 2005. In the meantime, new hosts have been detected for diseases caused by foliar pathogens (
Alternaria
spp.,
Stemphylium
spp.
Fusarium equiseti
,
Albifimbria verrucaria
,
Paramyrothecium roridum
), often as a consequence of climate change. The phytopathological situations of vegetable crops is discussed hereafter, with special emphasis on Italy, which is one of the most important vegetable production countries in Europe (not worldwide). The evolution of some diseases as a possible consequence of the current limitations in the use of chemicals, of the globalisation of the markets and/or of climate change is critically discussed. The disease management options that are currently available (e.g. the use of healthy planting material, host resistance, soil health, soilless systems, biological control, and integrated pest management) are discussed.
Local data inverse problem for the polyharmonic operator with anisotropic perturbations
Authors: Bhattacharyya Sombuddha , Kumar Pranav 
Published: March 2024

AbstractIn this article, we study an inverse problem with local data for a linear polyharmonic operator with several lower order tensorial perturbations. We consider our domain to have an inaccessible portion of the boundary where neither the input can be prescribed nor the output can be measured. We prove the unique determination of all the tensorial coefficients of the operator from the knowledge of the Dirichlet and Neumann map on the accessible part of the boundary, under suitable geometric assumptions on the domain.
