Authors: Son Byeng-Ju , Kim Ung , Nam Jong-Ho , Choi Kang-Un , Park Jong-Il , Son Jang-Won 
Published: April 2024

Abstract
Transcatheter aortic valve replacement is quickly becoming the standard of care for patients with severe aortic stenosis thanks to its minimally invasive nature and favorable outcomes. Recently, left ventricular pacing has been proposed as a safer alternative to traditional right heart pacing, which could simplify the transcatheter aortic valve replacement procedure overall, although procedural complications may still occur. This report describes a rare case of left ventricular pacing wire–induced acute severe mitral valve regurgitation during transcatheter aortic valve replacement.
Saccharina sporophytes settling on kelp cultivation rafts come from wild intertidal populations and not from the farmed cultivars

Published: April 2024

Abstract
Wild-type sporophytes of Saccharina japonica have been recurrently observed on the infrastructures of kelp farming rafts in China’s northern production region (Liaoning and Shandong provinces). However, there are few detailed reports delineating their origin, genetic attributes and affiliations with farmed populations. Using microsatellite molecular analyses, we furnish a comparative analysis of the populations sampled from these rafts at one of the historical kelp farming regions Rongcheng city (Shandong province), both before and after the “2021–2022 kelp farming disaster”, in conjunction with two field populations from nearby intertidal zones where natural populations prevail. The results show that the wild kelp populations on the kelp farming rafts in 2023 had originated from the wild populations dwelling in intertidal zones several kilometers away, rather than from the artificially cultivated kelp cultivars.
A sisterhood of constructions? A structural priming approach to modelling links in the network of Objoid Constructions
Authors: Bouso Tamara , Hundt Marianne , Van Driessche Laetitia 
Published: April 2024

Abstract
A central aim of Construction Grammar is to model links within the construct-i-con. This paper investigates three constructions that share one property: an atypical element in the object slot. The constructions are therefore not prototypically transitive. Structural priming (implemented with an automatic maze variant of self-paced reading) is used to test hypotheses on the relation among the Reaction Objoid (She smiled her thanks), the Cognate Objoid (She smiled a sweet smile or He told a sly tale), and the Superlative Objoid (She smiled her sweetest) Construction, and between two variants of the latter (They worked (at) their hardest). Results support transitivity as gradient: intransitive COCs prime the ROC and the SOC, whereas COCs with transitives only prime the ROC. For variants of the SOC, we find evidence of asymmetric priming with the bare SOC priming the at-SOC. Within-construction priming effects in the SOC are of greater magnitude than those with the at-SOC and the latter are weaker than those of the COC and of a rather different nature than those from the ROC. This suggests that speakers, rather than creating a constructeme between the bare and the at-SOC, store distinct but closely related constructions on a cline of transitivity.
𝑉-filtrations and minimal exponents for local complete intersections

Abstract
We define and study a notion of minimal exponent for a local complete intersection subscheme 𝑍 of a smooth complex algebraic variety 𝑋, extending the invariant defined by Saito in the case of hypersurfaces.
Our definition is in terms of the Kashiwara–Malgrange 𝑉-filtration associated to 𝑍.
We show that the minimal exponent describes how far the Hodge filtration and order filtration agree on the local cohomology

, where 𝑟 is the codimension of 𝑍 in 𝑋.
We also study its relation to the Bernstein–Sato polynomial of 𝑍.
Our main result describes the minimal exponent of a higher codimension subscheme in terms of the invariant associated to a suitable hypersurface; this allows proving the main properties of this invariant by reduction to the codimension 1 case.
A key ingredient for our main result is a description of the Kashiwara–Malgrange 𝑉-filtration associated to any ideal

Quenching of Disk-Shaped Components in Aqueous Polymer Solutions
Authors: Lübben T. , Frerichs F. , Barbieri M. , Buss L. , Riefler N. , Fritsching U. 
Published: April 2024

Abstract
In addition to various advantages over oil quenching, quenching in aqueous polymer solutions can also have disadvantages. Under certain conditions, “explosive” phenomena can occur when quenching steel components in such solutions, leading to pressure waves and vibrations in the quenching tank, which can even destroy the weld seams of the tank in the long term. After these processes were analyzed in the past when quenching cylindrical shafts, the processes occurring with horizontally charged disks have now been investigated. The main difference between these two geometries lies in the size of the lower disk end face, which significantly impedes the outflow of evaporated portions of the aqueous polymer solutions and thus has a pronounced influence on the cooling behavior of disk-shaped components. The investigations to be presented here were carried out in a laboratory quenching tank. The type and concentration of the polymer, the flow type and the diameter of the inner bore of the disks were varied. Temperature and conductivity were measured and audio and video recordings were made to characterize the resulting cooling processes. Selected quenching variants are presented in detail in the article. Furthermore, key figures for characterizing the various cooling variants are compared and discussed.

Authors: Samiappan Sumathi C , Mahesh Narayanan , Pandiyan Rajesh , Balakumar Srinivasan 
Published: April 2024

Abstract
The pervasive issue of micro and nanoplastics (MNPs) in the environment has escalated into a global concern, necessitating the exploration of innovative and efficient removal strategies. This review paper provides a comprehensive analysis of the application of carbon composites in mitigating MNPs, drawing upon a wide array of studies and technological advancements in the field. Carbon composites, known for their high surface area, porosity, and functional ability, offer a promising avenue for the adsorption, degradation, and removal of MNPs from various environmental matrices. We delve into the mechanisms underlying the interaction between carbon composites and MNPs, including physical adsorption, chemical binding, and photocatalytic degradation, highlighting the factors that influence these interactions, such as composite structure, surface chemistry, and environmental conditions. The review further categorizes carbon composites, such as activated carbon, carbon nanotubes, graphene, and biochar-based composites, examining their efficacy, limitations, and potential environmental impacts. A critical analysis of recent field and laboratory studies provides insights into these composites’ practical applications and performance in real-world scenarios. Additionally, we discuss the challenges and future directions for developing carbon composites, including scalability, regeneration, and the sustainable production of these materials. Carbon composites hold significant potential for efficient mitigation of MNPs, offering a viable solution to one of our time’s most pressing environmental challenges. However, further research is needed to optimize these materials for widespread application, enhancing their selectivity, capacity, and durability while minimizing unintended environmental consequences. This review aims to catalyze further investigation and innovation in the field, paving the way for developing more effective and sustainable technologies for mitigating micro and nanoplastics.

МОДЕЛЬ «НАЛЕЖНОГО УРЯДУВАННЯ» ЯК ШЛЯХ РЕФОРМУВАННЯ ПУБЛІЧНОЇ ПОЛІТИКИ В УКРАЇНІ
Authors: КОРОЩЕНКО Микола 
Published: April 2024

Досліджено модель «належного урядування» у контексті потреб реформування публічної політики в Україні з урахуванням сучасних реалій і можливостей держави. Актуальність даної проблеми пов’язана з тим, що перехід до модернової системи державного управління з сильними інституціями, підкріпленими верховенством права, вимагатиме від українського уряду кроків, які мають бути здійснені вже за часів військових дій, опрацювання тих стратегічних пріоритетів, які спрямують державу на траєкторію демократизації і євроінтеграції. Аргументовано, що нині модель «належного урядування» є однією з найпривабливіших альтернатив моделі державного управління, реалізація якої буде можливою тільки за виконання низки умов, додержання яких в Україні є проблемним з огляду на наслідки військової агресії. Утім, і сьогодні держава може зробити кроки для впровадження моделі «належного урядування». При цьому її базові постулати дозволяють говорити про те, що це не просто один з варіантів державного управління, а філософія життя в державі, яка передбачає співпрацю як основну форму взаємодії між різними учасниками тих процесів (соціальних, економічних, політичних, інформаційних), які характеризують усю різноманітну діяльність сучасної держави. Виокремлено проблеми, які заважають активному переходу України до даної моделі, але її імплементація повинна вирішити такі стратегічні завдання державного управління, як боротьба з корупцією, свобода ЗМІ, підвищення професіоналізму службовців, що неминуче постануть перед країною в післявоєнний час.

BACKGROUNDNearly 25% of antibiotics prescribed to children are inappropriate or unnecessary, subjecting patients to avoidable adverse medication effects and cost.METHODSWe conducted a quality improvement initiative across 118 hospitals participating in the American Academy of Pediatrics Value in Inpatient Pediatrics Network 2020 to 2022. We aimed to increase the proportion of children receiving appropriate: (1) empirical, (2) definitive, and (3) duration of antibiotic therapy for community-acquired pneumonia, skin and soft tissue infections, and urinary tract infections to ≥85% by Jan 1, 2022. Sites reviewed encounters of children &gt;60 days old evaluated in the emergency department or hospital. Interventions included monthly audit with feedback, educational webinars, peer coaching, order sets, and a mobile app containing site-specific, antibiogram-based treatment recommendations. Sites submitted 18 months of baseline, 2-months washout, and 10 months intervention data. We performed interrupted time series (analyses for each measure.RESULTSSites reviewed 43 916 encounters (30 799 preintervention, 13 117 post). Overall median [interquartile range] adherence to empirical, definitive, and duration of antibiotic therapy was 67% [65% to 70%]; 74% [72% to 75%] and 61% [58% to 65%], respectively at baseline and was 72% [71% to 72%]; 79% [79% to 80%] and 71% [69% to 73%], respectively, during the intervention period. Interrupted time series revealed a 13% (95% confidence interval: 1% to 26%) intercept change at intervention for empirical therapy and a 1.1% (95% confidence interval: 0.4% to 1.9%) monthly increase in adherence per month for antibiotic duration above baseline rates. Balancing measures of care escalation and revisit or readmission did not increase.CONCLUSIONSThis multisite collaborative increased appropriate antibiotic use for community-acquired pneumonia, skin and soft tissue infections, and urinary tract infection among diverse hospitals.

Study of Optical Performance and Structure of Yb/Al(1.5wt%Si) and Yb/Al(pure) Multilayers Designed for the 73.6 nm Range
Authors: Lai Bo , Qi Runze , Zhang Zhengbo , Wang Zhanshan 
Published: April 2024

The Yb/Al multilayer films exhibit excellent theoretical reflectivity in the 54-90nm wavelength range. This study attempted to incorporate 1.5% wt.% of Si impurities into Al to suppress the crystallization of Al, reduce interfacial roughness, and enhance the actual reflectivity of the prepared Yb/Al multilayer films. The internal microstructure changes of the film layers before and after Si impurity doping were investigated using GIXRR, AFM, and XRD techniques. The reflectivity of two types of multilayer films, Yb/Al(1.5wt.%Si) and Yb/Al(pure), was tested to evaluate the effect of Si impurity on the film performance.

Abstract

Chronic Obstructive Pulmonary Disease (COPD) is a common, costly, and morbid condition. Pulmonary rehabilitation, close monitoring, and early intervention during acute exacerbations of symptoms represent a comprehensive approach to improve outcomes, but the optimal means of delivering these services is uncertain. Logistical, financial, and social barriers to providing healthcare through face-to-face encounters, paired with recent developments in technology, have stimulated interest in exploring alternative models of care. The Healthy at Home study seeks to determine the feasibility of a multimodal, digitally enhanced intervention provided to participants with COPD longitudinally over six months. This paper details the recruitment, methods, and analysis plan for the study, which is recruiting 100 participants in its pilot phase. Participants were provided with several integrated services including a smartwatch to track physiological data, a study app to track symptoms and study instruments, access to a mobile integrated health program for acute clinical needs, and a virtual comprehensive pulmonary support service. Participants shared physiologic, demographic, and symptom reports, electronic health records, and claims data with the study team, facilitating a better understanding of their symptoms and potential care needs longitudinally. The Healthy at Home study seeks to develop a comprehensive digital phenotype of COPD by tracking and responding to multiple indices of disease behavior and facilitating early and nuanced responses to changes in participants’ health status. This study is registered at Clinicaltrials.gov (NCT06000696).
Offering a comfort diet for patient with tongue neoplasm in end of life - Case Report
Authors: Rodrigues Mariana Gabriela , de Carvalho Ricardo Tavares , Barbosa Renata Vieira , Varotto Bruna Luiza Roim , Santi Juliana Cristina Trombeta Dei , Crispim Douglas Henrique 
Published: April 2024

Abstract

Introduction: Oral cancer is a public health challenge in Brazil. Squamous cell carcinoma in the tongue is associated with late diagnosis and unfavorable outcomes. Palliative care aims to improve the patient's quality of life and involves shared decision-making between healthcare professionals and patients.
Case Report: A 65-year-old patient with a history of tongue cancer since 2006 underwent a total glossectomy. Tumor progression occurred leading to exposure of the oral cavity, resulting in a stage 4 oncological lesion with an extraoral oral communication. Due to the patient's loss of functionality and frailty, curative treatment became unfeasible. The patient expressed a desire to resume oral feeding despite the possibility of an unfavorable outcome.
Discussion:Despite the risks, it is considered relevant to accommodate the patient's wishes regarding feeding. During the offering of food a significant coughing episode with gastric secretion leakage, food egress through the tracheostomy, and vessel rupture in the ulcer region occurred during lesion cleaning after feeding. Initially, the severity of the condition was communicated to the patient and family, followed by manual compression with adrenaline and tranexamic acid to control bleeding. Given the bleeding location's severity, the patient's religious support was enlisted, and they chose to offer prayers and religious songs while the medical team attempted to address the complication.
Conclusion: The importance of balancing technical decisions and values in the care of terminal patients was evident, prioritizing the wishes of the patient and involving a multidisciplinary approach to assess discomforts and symptoms of the underlying disease.
A survey of primary angle closure knowledge and application by UK community-based optometrists
Authors: Jindal Anish , Nolan Winifred 
Published: April 2024

Abstract

Introduction
In 2022, UK guidance on the management and referral of primary angle closure (PAC) was published by the Royal College of Ophthalmologists (RCO) and the College of Optometrists (CoO). This study sought to investigate PAC knowledge and guidelines adherence of community-based optometrists (CBO).
Methods
An online survey was sent to CBO in July 2023 that asked about professional status, PAC investigations/risk factors, guideline application, and referral thresholds.
Results
Fifty-seven CBO with a median post-qualification experience of 19.0 years (IQR 9.3.4-24.8)completed the survey. Twenty-eight (49.1%) had a post-graduate qualification in glaucoma. A mean number of 4.8 95% CI (4.3-5.2) risk factors for PAC were identified. Thirty-two (56.1%) reported using the RCO and CoO guidelines, 38 (66.6%) reported referral of asymptomatic patients with risk factors and/or acute angle closure symptoms (AACS) with a limbal anterior chamber depth of grade 1, but 35 (61.4%) would refer on grade 1 alone. Confidence in monitoring a diagnosed PAC-suspect in the community was moderate using a 10-point Likert scale, median 7 (IQR 6-8). Thirty-seven (64.9%) would re-refer to the hospital eye service based on either IOP or AACS. Access to anterior segment optical coherence tomography was available to 37 (64.9%) optometrists where 16 (28.1%) had received training.
Conclusion
This study found there was moderate use of current guidelines for investigating of and onward referral for PAC. Our findings recommend further professional development in PAC for CBO. Further work is required to determine whether PAC guidelines have affected both the numbers and quality of referrals.
Synthesis, characterization and photocatalytic activation of zinc nanoparticles via biogenic methods
Authors: ALTUNER ELİF ESRA 
Published: April 2024

Abstract

In this study, zinc nanoparticles (Zn NPs) were synthesized from the leaves of the plant Hypericum calycinum L by the biogenic method. Ultra-violet visible spectrum (UV-Vis), Fourier transmission electron spectroscopy (FTIR), transmission electron microscopy (TEM), and X-Ray were used to examine the absorbance, vibration bands, morphological structure, particle size, and crystalline size of the synthesized Zn NPs, respectively. Diffraction characterization (XRD) was performed. According to the results obtained, it was calculated that NPs gave peaks in the absorbance ranges of 274 and 370 nm, had a size of 29.066 ± 10.561 nm, and their crystalline size was 16 nm. Then, photocatalytic processes were started for the removal of methylene blue (MB) dye by combining the catalysis of NPs under the photocatalysis of sunlight. The degradation process provided by photocatalytic processes was carried out every half hour for 150 minutes. As a result of 150 minutes, the photodegradation efficiency was calculated to be 70%. This study supports future photodegradation studies for the removal of waste dyestuffs.
