Background and objectives

Severe pneumonia is the leading cause of death among young children worldwide, disproportionately impacting children who lack access to advanced diagnostic imaging. Here our objectives were to develop and test the accuracy of an artificial intelligence algorithm for detecting features of pulmonary consolidation on point-of-care lung ultrasounds among hospitalized children.

Methods

This was a prospective, multicenter center study conducted at academic Emergency Department and Pediatric inpatient or intensive care units between 2018–2020. Pediatric participants from 18 months to 17 years old with suspicion of lower respiratory tract infection were enrolled. Bedside lung ultrasounds were performed using a Philips handheld Lumify C5-2 transducer and standardized protocol to collect video loops from twelve lung zones, and lung features at both the video and frame levels annotated. Data from both affected and unaffected lung fields were split at the participant level into training, tuning, and holdout sets used to train, tune hyperparameters, and test an algorithm for detection of consolidation features. Data collected from adults with lower respiratory tract disease were added to enrich the training set. Algorithm performance at the video level to detect consolidation on lung ultrasound was determined using reference standard diagnosis of positive or negative pneumonia derived from clinical data.

Results

Data from 107 pediatric participants yielded 117 unique exams and contributed 604 positive and 589 negative videos for consolidation that were utilized for the algorithm development process. Overall accuracy for the model for identification and localization of consolidation was 88.5%, with sensitivity 88%, specificity 89%, positive predictive value 89%, and negative predictive value 87%.

Conclusions

Our algorithm demonstrated high accuracy for identification of consolidation features on pediatric chest ultrasound in children with pneumonia. Automated diagnostic support on an ultraportable point-of-care device has important implications for global health, particularly in austere settings.

Published: August 2024

The characterization and analysis of rock types based on acoustic emission (AE) signals have long been focal points in earth science research. However, traditional analysis methods struggle to handle the influx of big data. While signal processing methods combined with deep learning have found widespread use in various process analyses and state identification, effective feature extraction using progressive fusion technology still faces challenges in the field of intelligent rock type identification. To address this issue, our study proposes a novel framework for rock type identification based on AE and introduces a new signal identification model called 3CTNet. This model integrates convolutional neural networks (CNNs) and Transformer encoder, intelligently identifying AE of different rock fractures by establishing dependencies between adjacent positions within the data and gradually extracting advanced features. Furthermore, we experimentally compare five oversampling methods, ultimately selecting the adaptive synthetic sampling method (ADASYN) to balance the dataset and enhance the model’s robustness and generalization ability. Comparison of the internal structure of our model with a series of time series processing models demonstrates the effectiveness of the proposed model structure. Experimental results showcase the high identification accuracy of the intelligent rock type identification model based on 3CTNet, with an overall identification accuracy reaching 98.780%. Our proposed method lays a solid foundation for the efficient and accurate identification of formation rock types in geological exploration and oil and gas development endeavors.

Introduction

The improvement in diagnosis and treatment for nasopharyngeal carcinoma (NPC) has shifted the pattern of failure toward distant metastasis. This study aimed to develop a simplified prognostic scoring model to predict distant metastatic free survival (DMFS) for NPC patients.

Materials and methods

Patients with non-metastatic NPC were identified from a retrospective cohort diagnosed between 2010 and 2018. Flexible parametric survival analysis was used to identify potential predictors for DMFS and establish a scoring model. The prognostic accuracy between the 8th AJCC system and the scoring model was compared using Harrell’s C-index.

Results

Of the total 393 patients, the median follow-up time was 85 months. The 3-year DMFS rate was 83.3%. Gender, T-stage, pre-EBV (cut-off 2300 copies/ml), and the number of metastatic lymph node regions were identified as independent risk factors for distant metastasis and were included in the final scoring model. Our established model achieved a high C-index in predicting DMFS (0.79) and was well-calibrated. The score divided patients into two categories: low-risk (score 0–4) and high-risk (score 5–7), corresponding with the predicted 3-year DMFS of 96% and 64.5%, respectively.

Conclusions

A feasible and applicative prognostic score was established and validated to discriminate NPC patients into low- and high-risk groups.
Perception and coping mechanisms of patients with diabetes mellitus during the COVID-19 pandemic in Ibadan, Nigeria
Authors: Tunji-Adepoju Olajumoke Ololade , Afolabi Bolarinwa Obasanjo , Aboagye Richard Gyan , Balogun Williams O.
Published: August 2024

Background

The 2019 coronavirus disease (COVID-19) ushered in a period of fear and uncertainty, resulting in structural instability across the globe. Vulnerable individuals, such as patients with diabetes mellitus, are predispose to have adverse effects and complications of COVID-19 when infected. We explored the perception of diabetes mellitus patients during the COVID-19 pandemic and their coping mechanisms at the University College Hospital, Ibadan.

Methods

We employed an exploratory qualitative study design to explore diabetes mellitus patients’ perceptions and coping mechanisms during the COVID-19 pandemic. A purposive sampling technique was used to recruit 32 participants (2 health professionals and 30 diabetes mellitus patients). In-depth interviews were used to collect the data from the participants. All the recorded audio data were transcribed verbatim and exported to NVivo software for thematic data analyses.

Results

Most diabetes mellitus patients were not fearful of the pandemic but were optimistic that it would not affect their health. Mechanisms such as the usage of herbal medicines and adherence to COVID-19 precautionary measures were noticed among patients. The study also revealed that the hospital’s coping mechanism during the COVID-19 pandemic include prolonged appointments, limiting the number of patients attended per clinic day, and the provision of telehealth service. Patients in our study utilised negative coping mechanisms such as reduced drug dosages, subscriptions to cheaper drug brands, and reliance on religious institutions rather than a clinic for health instructions.

Conclusions

The study has shown that diabetes mellitus patients were not fearful of the COVID-19 pandemic. The utilisation of telehealth, encouragement of daily monitoring of sugar levels, provision of avenues for a medication review, and adherence to the safety protocols were coping mechanisms employed by the health system and diabetes mellitus patients. We recommend that the government and other healthcare stakeholders reinforce the resilience of diabetes mellitus patients by alleviating their health burdens during the pandemic. This could be done by subsidizing the prices of drugs, tests, and consultation fees for patients with diabetes mellitus. Also, more efforts should be made to elevate the health system through the reduction in waiting and appointment times in the diabetes clinic and employing more health personnel in the clinic.
Impact of corporate environmental uncertainty on environmental, social, and governance performance: The role of government, investors, and geopolitical risk
Authors: Guo Xiao , Cheng Pengfei , Choi Baekryul
Published: August 2024

Corporations face multifaceted environmental uncertainties (EU) in today’s dynamic global economic environment. Such uncertainties profoundly affect corporate operations and pose significant challenges to their environmental, social, and governance (ESG) performance. Therefore, using data from Chinese A-share listed corporations from 2009 to 2021, we empirically analyze the impact of the EU on ESG performance. The results demonstrate that the EU significantly negatively impacts ESG performance, indicating that corporations frequently find it difficult to implement and maintain high-standard ESG policies and practices effectively. Additionally, they reveal that the EU inhibits the improvement of ESG performance by increasing corporate financing constraints (KZ). Lastly, this study explores the role of government subsidies (GOV), investor attention (IA), and geopolitical risks (GPR) as moderating variables. We discover that GOV can mitigate the negative impact of the EU on KZ because they provide additional resources that help corporations maintain their ESG in uncertain environments. Furthermore, IA can reduce the adverse impact of KZ on ESG. Positive moderating effects result from ESG issues; the capital they provide effectively reduces corporate KZ, thus enabling corporations to maintain good ESG performance despite operating in highly uncertain environments. However, due to the increased asymmetry of information in economic markets caused by geopolitical tensions, GPR exacerbates the negative impact of the EU on ESG performance, thus leading to an increase in KZ. These findings offer new perspectives on understanding how these moderating effects affect corporate ESG strategies.

Framework for mapping absorptive capacity as an enabler of effective technology transfer: A case study of the innovative PEEPOWER technology
Authors: Lamere Maryam , Omar Basil , Saad Mohammed , Ieropoulos Ioannis , Brodie Lisa
Published: August 2024

In its comprehensive sense, a technology goes beyond the hardware or system to include associated skills and knowledge. Whilst this definition has been acknowledged across the literature, there is a gap in practices reflected during technology transfer processes. This article aims to investigate measures that can be taken by technology providers and recipients to effectively incorporate knowledge and skills sharing during a technology transfer. Conceptual frameworks were developed and used to inform empirical research. The case study of the PEEPOWER technology is carried out to consolidate theory with practice. The PEEPOWER technology is illustrated on a ‘techberg’ showing all elements of the technology beyond the hardware. An insight into the level of effectiveness of the PEEPOWER transfer to Kisoro, Nairobi and Durban is obtained through a qualitative analysis of interview responses, by looking at the extent of knowledge sharing and the absorptive capacity of the technology recipient. The main recommendations are to (1) adopt a knowledge exchange approach as opposed to a unidirectional knowledge transfer from the technology provider to the technology recipient, (2) establish good relationships with local partners and develop a good understanding of the local context and (3) manage expectations about innovations and ensure intellectual property protection during knowledge exchange.
La familia, un aliado indispensable para fomentar la lectura desde los espacios profesionales
Authors: Corchete Sánchez Teresa
Published: August 2024

La literatura escrita para niños y adolescentes cuenta con muchos ejemplos de historias cuya trama y personajes se perfilan en torno a las relaciones familiares. Son libros que conectan la ficción y la información con lo que para esos lectores resulta cotidiano y reconocible, situando a la familia en el centro del argumento. Este artículo recala en el espacio familiar analizando los factores que determinan el modo en el que la lectura se integra dentro de los hogares, como paso previo a la exposición de algunas acciones de promoción de la lectura que se pueden articular desde los espacios profesionales que trabajan con familias. Se inicia con una serie de reflexiones sobre el propio concepto de la lectura, los significados que esta adquiere en el momento presente y la utilidad y beneficios que aporta su práctica. Se analiza después el papel de los padres, que se configuran como intermediarios imprescindibles del trabajo que realiza el promotor de la lectura. Finalmente se aborda el rol que el mediador profesional ejerce en ese proceso. Todo ello se considera desde las oportunidades y amenazas que la tecnología digital plantea al respecto.

Authors: Fraile Prieto Teresa , Soto Vázquez José , Pérez Parejo Ramón , Pantoja Chaves Antonio
Published: August 2024

El siglo XIX fue un momento fundamental para el desarrollo de la educación primaria en el Estado español. La educación pública básica se fue estabilizando paralelamente a los avatares políticos y sociales del país, estableciendo unos cimientos que resultan esenciales para comprender las estructuras organizativas actuales, así como algunos de sus lastres. A partir de los datos recopilados en publicaciones previas, en esta investigación elaboramos la información relativa a la provincia de Badajoz durante el periodo comprendido entre 1857 y 1900, como caso de estudio particular, para presentar un panorama de lo que fue la educación primaria en esas fechas del siglo XIX. Partiendo de dichos datos pueden extraerse conclusiones en torno a las características demográficas y sociopolíticas de la distribución de las escuelas públicas de instrucción primaria en un momento decisivo para la educación española.

Una herencia en conflicto. Auge y disolución de una casa exportadora de lana en el valle del Ebro (siglo XVIII)
Authors: Zabalza Seguín  Ana
Published: August 2024

El texto analiza la figura de Agustín de Sesma y Sierra (1664-1738), hombre de negocios asentado en la ciudad navarra de Corella, junto a las aduanas con Castilla, donde se dedicaba a la compra de lana fina castellana para exportarla sobre todo a Francia y Holanda a través del puerto de Bayona. Fue también arrendatario de rentas reales. Aunque en buena medida había heredado haberes y saberes de la anterior generación, él va a dar un notable impulso a todas estas actividades, y va a aprovechar las oportunidades de negocio abiertas por la guerra de Sucesión española. Padre de una familia muy numerosa, va a desplegar una pensada política en la transmisión de su cuantioso patrimonio, asociando a los varones a su negocio pero destinando al hijo más joven a una carrera de servicio a la Monarquía en el seno de la Armada. La asimetría en el tratamiento de hombres y mujeres desencadenará una batalla procesal que pondrá fin a la casa comercial en 1746.
Hacia la modernidad: trayectorias de las familias nobles leonesas vinculadas a la monarquía borbónica: los Castañón Guillamas y Rebolledo Quijada. 1700-1870
Authors: Bartolomé Bartolomé Juan Manuel
Published: August 2024

Se analiza la trayectoria de la nobleza leonesa hacia roles de liderazgo en la administración borbónica. Las familias Castañón Guillamas y Rebolledo Quijada, a través de sus vínculos con la monarquía borbónica, lograron destacar social y políticamente durante el siglo XVIII y principios del XIX. Frente a la idea tradicional de que la burguesía fue el principal agente de modernización en España, se argumenta que sectores específicos de la nobleza, vinculados al gobierno borbónico, lideraron los cambios políticos y administrativos que marcaron el fin del Antiguo Régimen.
Los racioneros de la catedral de Murcia y la transmisión de su patrimonio a sus familiares en la primera mitad del siglo XVIII
Authors: Irigoyen López  Antonio
Published: August 2024

En este trabajo se pretende analizar cómo los racioneros de la catedral de Murcia transmitieron su patrimonio a sus familiares, partiendo de la hipótesis de que los eclesiásticos actuaron de este modo en respuesta a las obligaciones que les imponía el parentesco. Los testamentos van a ser la fuente utilizada y se procederá a clasificarlos en función del grado del beneficio que hicieron a sus parientes. Asimismo, se estudiarán las formas empleadas por los prebendados para favorecerlos, prestando especial atención al nombramiento de herederos universales, a los legados y mandas y a la fundación de vínculos y mayorazgos. Se verá que los racioneros trataron de ayudar a las líneas familiares más desprotegidas. Por esta razón, las principales beneficiarias serán las mujeres, en especial, las sobrinas y las hermanas.

Authors: Kayal Maia , Posner Hannah , Jimenez Darwin , Huang Justin , Dubinsky Marla C. , Colombel Jean Frederic
Published: August 2024

INTRODUCTION:

The aim of this study was to report the frequency and impact of endoscopic response and remission on the risk of subsequent pouchitis in patients with Crohn's disease–like pouch inflammation (CDLPI) on therapy.

METHODS:

This was a single-center retrospective study of patients older than 18 years with CDLPI on therapy.

RESULTS:

Among 110 included patients with CDLPI in clinical remission, endoscopic remission was not significantly associated with a reduced risk of subsequent pouchitis when compared with endoscopic response.

DISCUSSION:

Endoscopic response, not remission, is sufficient to reduce the risk of subsequent pouchitis in patients with CDLPI.
Proton-Pump Inhibitors and Cardiovascular Adverse Events: A Meta-Analysis of Randomized Controlled Trials
Authors: Mosholder Andrew D. , Hada Manila , Leishear Kira
Published: August 2024

INTRODUCTION:

Some observational studies suggest a cardiovascular risk from proton-pump inhibitor (PPI) treatment, but observational data may be subject to bias. We conducted a meta-analysis of randomized controlled trial data on cardiovascular events during PPI treatment.

METHODS:

Manufacturers of PPIs provided data from their PPI clinical trial programs. We included randomized trials with at least 100 subjects, treatment duration >30 days, and a non-PPI comparator (active or placebo). We obtained person-time of exposure per trial, to calculate summary incidence rate ratios (primary analysis) and incident rate differences (secondary analysis). Our primary composite outcome was major adverse cardiovascular events-plus (MACE+), which included nonfatal myocardial infarction, nonfatal stroke, fatal cardiovascular adverse events, hospitalization for unstable angina, or coronary revascularization; events were adjudicated blindly.

RESULTS:

Cardiovascular outcomes were infrequent in randomized trials of PPIs, and our primary analysis found no overall association (summary incident rate ratio, MACE+ events, PPI:placebo, 0.72) (95% confidence interval 0.42–1.26). There was some heterogeneity by indication category, and by the incidence rate difference metric, gastroesophageal reflux disorder trials had 1.04 (95% confidence interval 0.58–1.50) excess MACE+ events per 100 person-years of treatment vs placebo. Comparisons with active controls generally showed positive incidence rate differences with PPI treatment.

DISCUSSION:

Overall, we found no association of cardiovascular events with PPI treatment. Cardiovascular events appeared more frequent with PPI treatment in gastroesophageal reflux disorder trials, but results from this subgroup should be interpreted with the limitations of the analysis in mind, including sparse outcome counts and lack of individual patient data.
Por uma indisciplinaridade sociossemiótica
Authors: Abreu Diego Candido
Published: August 2024

O objetivo principal deste artigo é construir uma proposta de diálogo teórico-analítico entre a Linguística Sistêmico-Funcional (Halliday, 1994) e a Linguística Aplicada Indisciplinar (Moita Lopes, 2013). Para tanto, delineiam-se as bases epistemológicas e conceituais que estruturam ambas as áreas, colocando em destaque a visão de linguagem advogada por cada um dos campos do saber. À luz desse quadro de ideias e concepções, discutem-se os pontos de convergência e complementariedade entre ambos os arcabouços linguísticos com o fito de erigir os fundamentos de uma interface entre as matrizes teóricas. Após esse percurso de discussões, um exemplo de análise empreendida a partir de uma interface entre a Linguística Sistêmico-Funcional, com o auxílio do Sistema de Avaliatividade (Martin; White, 2005), e a Linguística Aplicada é apresentado com o intuito de ilustrar o modelo de diálogo defendido e as possibilidades de tal caldeamento. Como evidenciado pela peça analítica iluminada, a articulação entre ambos os cabedais teóricos fornece um ferramental analítico dotado de categorias que, ao mesmo tempo que nos permitem mapear os dados linguísticos com maior grau de sistematicidade, viabilizam o estudo dos fenômenos discursivos para além de sua materialidade linguística.

O objetivo deste trabalho foi compreender, por meio da história oral temática, as trajetórias escolares e não escolares entre o trabalho, a educação e religiosidade da nossa interlocutora, Vó Paulina. O estudo possui caráter qualitativo, embasado pela história oral e análise descritiva. Como suporte teórico, realizamos diálogos com Marin (2018), Stropasolas (2006), Salles (2005), Camargo, Scorsolini-Comin, Santos (2018), entre outros, que nos ajudaram a ter uma melhor compreensão do campo temático. Identificando o contexto em que Vó Paulina estava inserida e todos os seus vieses, percebemos o atravessamento da perspectiva da educação rural. Destacamos que a nossa colaboradora viveu um modelo de educação pautado no trabalho, no qual foi inserida ainda na infância, precisando, desde cedo, de saber lidar com a terra, inicialmente trabalhando na lavoura e, posteriormente, em sua fase adulta, dividindo-se entre o campo de lavoura e o trabalho com o dom, por meio da religiosidade. É importante salientar que estudos dessa natureza vão atestar que precisamos avançar muito na construção de outras perspectivas sobre infância para que histórias como a de Vó Paulina estejam apenas transcritas em narrativas realizadas nas pesquisas de suas netas, que hoje ocupam as universidades públicas do Brasil.

A autorregulação da aprendizagem envolve a capacidade do indivíduo de gerenciar os próprios pensamentos, as emoções e os comportamentos para atingir objetivos de aprendizagem. Este texto é um relato de experiência acerca de uma formação discente em autorregulação da aprendizagem realizada com estudantes da Educação de Jovens, Adultos e Idosos (EJA) de uma escola de Belo Horizonte/MG. Considera-se que a aprendizagem autorregulada é um tema relevante, mas insuficientemente explorado na EJA. A formação deve contribuir para que estudantes e professores dessa modalidade possam lidar com a EJA de forma auto-orientada, de modo a favorecer o melhor aproveitamento da experiência escolar.

Published: August 2024

La aproximación a las relaciones entre Música, Literatura y Poder en la España Moderna (1500-1750) carece de estudios sistemáticos e interdisciplinares que procedan del diálogo entre grupos de investigación sobre Patrimonio Musical, Literatura del Siglo de Oro y Barroco, e Historia Moderna. Este libro colectivo nace así de una red de siete grupos de investigación (Universidad de Castilla-La Mancha, Universidad de Extremadura, Universidad de Granada, Universidad Autónoma de Barcelona y CSIC) que pretende estrechar los vínculos entre especialistas de distintas áreas en torno a las relaciones que se establecen entre Música y Literatura en el ámbito de los géneros dramáticos, líricos y narrativos, al servicio del Poder político como instrumentos definitivos de legitimación y propaganda dentro de sus espacios celebrativos. Se han examinado así con detalle los mecanismos retóricos, técnicos, estéticos e instrumentales de estas producciones en donde la realidad musical y literaria confluyen, así como su dimensión dentro de un programa político concebido para las artes y orientado hacia la consolidación y publicidad del poder del Estado y sus instituciones. Con una notable vocación interdisciplinar se aborda aquí la recepción e interpretación de las fuentes musicales recuperadas y de sus textos poéticos asociados, procedentes de espacios celebrativos civiles y religiosos, así como su dimensión política y propagandística especialmente en la fiesta barroca.

Authors: Yang Caixia , Song Zhiying
Published: August 2024

In recent years, researchers have been utilizing nanotechnology more and more to study diabetic complications, with a particular emphasis on prevention and treatment. In this investigation, we analyzed the effects of Acroptilon repens extract on iron nanoparticles (FeNPs), which demonstrated significant anti-diabetic characteristics both in living organisms and in laboratory settings. To assess the effectiveness of the FeNPs produced through the interaction of iron salt solutions stabilized by A. repens extract, we utilized a range of methodologies. The FeNPs were manufactured in a spherical shape, ranging in size from 10 to 60 nm. During the in vivo experiment, gestational diabetes was induced through streptozotocin (STZ) intraperitoneal injection. The animals were then categorized into four groups: FeNPs-60 μg/kg group, FeNPs-120 μg/kg group, normal pregnancy group, and gestational diabetes mellitus group (n = 10). FeNPs were administered intragastrically for 25 days. On the final day, the levels of ALP, AST, ALT, and blood glucose in the serum samples were assessed. Following tissue processing, 5 μm liver sections were prepared and the overall volume of the hepatic arteries, bile ducts, central vein, portal vein, sinusoids, hepatocytes, and liver, were approximated. FeNPs have the potential to reduce the elevated levels of ALP and AST enzymes. In gestational diabetes rats, the administration of FeNPs lead to a decrease in blood glucose levels. The administration of STZ significantly increased the volume of sinusoids and hepatocytes. However, after the treatment with a high dose of FeNPs, there was a notable decrease in their volume. In contrast, the volume of the bile ducts and portal vein remained unchanged in the experimental groups. Nevertheless, the volume of the hepatic arteries and central vein exhibited changes due to the presence of FeNPs. The current study showcases the hepatoprotective and anti-diabetic characteristics of FeNPs, providing a potential option as a supplement to prevent gestational diabetes mellitus while also offering hepatoprotective benefits.
An efficient hybrid spectrum sensing algorithm to enhance the performance of optical NOMA waveforms using 256-QAM
Authors: Sharma Himanshu , Yadav Surendra , Kumar Arun
Published: August 2024

The ever-increasing demand for bandwidth in optical networks necessitates efficient spectrum utilization. To address this challenge, this paper proposes a novel hybrid spectrum sensing algorithm tailored explicitly for 256-QAM (Quadrature Amplitude Modulation) optical communication waveforms. The proposed algorithm combines the strengths of energy detection and cyclostationary feature detection to overcome the limitations of individual methods. Energy detection (ED) provides fast and low-complexity sensing, while cyclostationary feature detection offers higher accuracy and sensitivity. First, ED is employed for rapid initial spectrum assessment. Subsequently, matched filter (MF) detection is selectively applied only to frequency bands identified as potentially occupied by primary users based on the energy detection results. This selective approach significantly reduces computational complexity while maintaining high detection accuracy. The results demonstrate significant improvements in detection accuracy, sensitivity, and computational efficiency compared to existing methods. In particular, the hybrid algorithm performs better in scenarios where weak 256-QAM signals coexist with strong primary users, showcasing its effectiveness in dynamic spectrum-sharing applications. This work contributes significantly to optical spectrum sensing by offering an efficient and accurate solution for advanced radio systems. The proposed hybrid algorithm paves the way for improved spectrum utilization and facilitates the development of high-performance, next-generation optical networks. The projected method obtained a gain of −200 as compared with the existing methods.

Published: August 2024

Fused silica with surface structures has potential applications in microfluidic, aerospace and other fields. To fabricate structures with high dimensional accuracy and surface quality is of paramount importance. However, it is indeed a challenge to strike a balance between accuracy and efficiency at the same time. Here, a temporally shaped femtosecond laser Bessel-beam-assisted etching method with dual-control of incubation effect is proposed to achieve this balance. Instead of layer-by-layer ablation continuously with Gaussian pulses, silica is modified discretely by double pulse Bessel beam with one single layer. During the modification process, incubation effect is dual-controlled in single shot process and spatial scanning process to generate even modified region efficiently. Then, the modified region is etched to form designed structures such as microholes, grooves, etc. The proposed method exhibits high efficiency for fabrication of surface structures in fused silica.

Published: August 2024

In the rapidly evolving field of plasmonic metasurfaces, achieving homogeneous, reliable, and reproducible fabrication of sub-5 nm dielectric nanogaps is a significant challenge. This article presents an advanced fabrication technology that addresses this issue, capable of realizing uniform and reliable vertical nanogap metasurfaces on a whole wafer of 100 mm diameter. By leveraging fast patterning techniques, such as variable-shaped and character projection electron beam lithography (EBL), along with atomic layer deposition (ALD) for defining a few nanometer gaps with sub-nanometer precision, we have developed a flexible nanofabrication technology to achieve gaps as narrow as 2 nm in plasmonic nanoantennas. The quality of our structures is experimentally demonstrated by the observation of resonant localized and collective modes corresponding to the lattice, with Q-factors reaching up to 165. Our technological process opens up new and exciting opportunities to fabricate macroscopic devices harnessing the strong enhancement of light–matter interaction at the single nanometer scale.
Robustness and dynamical features of fractional difference spacecraft model with Mittag–Leffler stability
Authors: Sultana Sobia
Published: August 2024

Spacecraft models that mimic the Planck satellite’s behaviour have produced information on cosmic microwave background radiation, assisting physicists in their understanding of the composition and expansion of the universe. For achieving the intended formation, a framework for a discrete fractional difference spacecraft model is constructed by the use of a discrete nabla operator of variable order containing the Mittag–Leffler kernel. The efficacy of the suggested framework is evaluated employing a numerical simulation of the concerning dynamic systems of motion while taking into account multiple considerations such as exterior disruptions, parameterized variations, time-varying feedback delays, and actuator defects. The implementation of the Banach fixed-point approach provides sufficient requirements for the presence of the solution as well as a distinctive feature for such mechanisms Furthermore, the consistent stability is examined. With the aid of discrete nabla operators, we monitor the qualitative behavioural patterns of spacecraft systems to provide justification for structure’s chaos. We acquire the fixed points of the proposed trajectory. At each fixed point, we calculate the eigenvalue of the spacecraft system’s Jacobian matrix and check for zones of instability. The outcomes exhibit a wide range of multifaceted behaviours resulting from the interaction with various fractional orders in the offered system. To maintain stability and synchronize the system, nonlinear controllers are additionally provided. The study highlights the technique’s vulnerability to fractional-order factors, resulting in exclusive, changing trends and equilibrium frameworks. Because of its diverse and convoluted behaviour, the spacecraft chaotic model is an intriguing and crucial subject for research.

Published: August 2024

Objectives

BLM, a member of the RecQ helicase family, plays an important role in DNA repair, and its biallelic mutations cause autosomal recessive Bloom syndrome, a disease characterized by elevated levels of sister chromatid exchange (SCE) in affected individuals and hereditary cancer susceptibility in carriers. This study aims to investigate genomic instability in breast cancer patients carrying heterozygous variants in the BLM gene.

Methods

Spontaneous chromosome breakage count and SCE counting were performed on newly drawn blood cultures, both spontaneous and stimulated. The spontaneous breakage count was conducted alongside control samples. In SCE analysis, 0–10 per metaphase was considered normal, 10–40 borderline, and counts above 40 were considered high.

Results

The study included 26 patients and one healthy control at each session. The clinical and pathological characteristics of the patients were evaluated. The analyses revealed borderline-level increased SCE rates in only one patient. No increase in spontaneous breakage count or SCE analysis was observed in other individuals compared to controls.

Conclusions

Increased genomic instability was not observed in the analyzed patient group. These results can lead to multiple interpretations. The variants carried in the BLM gene in the patient group may be of low pathogenicity, or increased instability compared to controls may not be necessary for heterozygous variants. Additionally, our patient group may not have been exposed to a genotoxic effect causing genomic instability. These results could also indicate a favorable position in terms of avoiding chemotherapy and radiotherapy complications.
Adaptation as Means of Revising Gender Relations in Brian Friel’s A Month in the Country
Authors: Bach Anikó
Published: August 2024

The aim of the present paper is to investigate Brian Friel’s A Month in the Country, in which the Irish writer refocuses attention to enhance the psychological nature of the drama and to allow space to the female voice that is given less emphasis in the original. To reveal the differences between Turgenev’s play and the adapted version of it, I will try to answer the question of to what extent the changes introduced by Friel contribute to the debates on gender relations in contemporary Irish society.

The HIV Index is a validated self-report scale of engagement in HIV care previously correlated with future retention and virologic suppression. However, its performance in a monoethnic Latinx population has not been studied. We evaluated the HIV Index among Latinx persons living with HIV in the Centers for AIDS Research Network of Integrated Clinical Systems cohort and performed multivariable logistic regression to estimate its association with primary outcomes of suboptimal retention (not keeping 100% of HIV clinic appointments) and virologic suppression (HIV viral load <200 copies/mL). The mean Index score was 4.5 (standard deviation 0.6) in both analytic samples, indicative of feeling well-engaged. Higher Index scores were associated with lower odds of suboptimal retention (OR = 0.12, 95% CI [0.03, 0.54], p = .005), however, there was no association between Index score and virologic suppression. The HIV Index is useful for assessing engagement and retention among Latinx PLWH in routine care.

A investigação da linguagem como prática social mediadora da experiência do relacionamento entre os seres humanos tem sido uma opção de muitos pesquisadores da linguagem, tributários da filosofia de Mikhail Bakhtin e seu Círculo. O objetivo deste artigo é discutir a questão de o ato de autoria, bem como o de leitura e o de tradução, serem processos dialógicos de interação. São dialógicos por serem práticas discursivas realizadas pela interação entre interlocutores social e historicamente situados.  A leitura e a tradução são vistas como práticas culturais situadas que atuam não só mediando, mas também criando cultura. Sob essa perspectiva, são práticas de natureza eminentemente dialógica e autoral. Ao ler e ao traduzir, é necessário que sejam feitas escolhas e estas acabam por produzir um novo texto e um novo autor.
