Abstract
The current work aimed at investigating experimentally the weave pattern effects on the mechanical and dynamic behaviors of polymer matrix composite laminates. The laminates composed of three different weave types (plain, satin, and twill) of woven glass fabric and STR Medapoxy epoxy resin were fabricated via vacuum molding. Static bending experiments were applied to determine the influence of the weave pattern on the mechanical characteristics of the samples. The failure behaviors of the samples were also examined by optical and Scanning Electron Microscopy (SEM) analyses. Additionally, Dynamic Mechanical Analysis (DMA) in the temperature range of 25–200 °C at 1 Hz frequency was conducted to investigate the dynamic characteristics of the samples. It was found that the samples having satin weave type had the best flexural modulus followed by the plain and twill weaves. However, the twill weave laminates exhibited better storage modulus at glass transition temperature values (T
g) compared to the others. Also, an increase of 3.3 °C in glass transition temperature was observed compared to that of neat resin. This was attributed to the better fiber/matrix adhesion and the lower molecular mobility in the polymer chain by the addition of glass twill fibers.

Abstract
The present study explores the contributions of significant others to 10 Iranian English language teachers’ well-being by drawing on self-determination theory. We define significant others as individuals who play a key role in the emotional dynamics that teachers experience and serve as the impetus for those emotional experiences. Data were collected from questionnaires, narrative frames, and semi-structured interviews. Analyses of the data revealed that significant others contributed to the teachers’ competence (becoming more agentic), autonomy (alignment and emotion labor), and relatedness (interpersonal emotionality) in relation to their well-being. Our findings indicate that significant others define teachers’ relational well-being through shaping their identities, agencies, and emotions in interpersonal interactions and relationships. We also discuss implications for pre-service and in-service teachers as well as for teacher educators, and emphasize the need to develop a more nested understanding of well-being and the myriad of factors influencing it.

Abstract
With the refinement and scientificization of sports training, the demand for sports performance analysis in the field of sports has gradually become prominent. In response to the problem of low accuracy and poor real-time performance in human pose estimation during sports, this article focused on volleyball sports and used a combination model of OpenPose and DeepSORT to perform real-time pose estimation and tracking on volleyball videos. First, the OpenPose algorithm was adopted to estimate the posture of the human body region, accurately estimating the coordinates of key points, and assisting the model in understanding the posture. Then, the DeepSORT model target tracking algorithm was utilized to track the detected human pose information in real-time, ensuring consistency of identification and continuity of position between different frames. Finally, using unmanned aerial vehicles as carriers, the YOLOv4 object detection model was used to perform real-time human pose detection on standardized images. The experimental results on the Volleyball Activity Dataset showed that the OpenPose model had a pose estimation accuracy of 98.23%, which was 6.17% higher than the PoseNet model. The overall processing speed reached 16.7 frames/s. It has good pose recognition accuracy and real-time performance and can adapt to various volleyball match scenes.
A hybrid approach combining OFC and FSO for multichannel connectivity
Authors: Khalil Iqra , Noor Kanza , Qamar Farhan , Shahzadi Romana 
Published: April 2024

Abstract
This paper presents a novel approach of establishing a multichannel optical communication link, combining optical fiber cable (OFC) and free space optics (FSO) technology. By leveraging multiple lengths of optical fiber and FSO links, along with optical amplifiers to counteract attenuation, our proposed hybrid system incorporates four channels operating within the 1550 nm window. This model is specifically designed to address communication challenges in scenarios such as unplanned urban layouts, multistory buildings, or rugged terrains where traditional optical fiber deployment is impractical. By integrating FSO for the fronthaul and optical fiber for the backhaul, our system enhances transmission capacity, thereby supporting the requirements of next-generation networks and alleviating bottlenecks and connectivity issues at the last or first mile. This innovative approach holds promise for internet service providers, enterprises, and industrial networks operating in demanding environments. Furthermore, it can serve as a vital tool for restoring emergency communication links in the aftermath of disasters such as earthquakes or floods, where traditional wired optical infrastructure may be compromised.

Published: April 2024

Abstract

Context
Clinical clerkships provide osteopathic medical students the opportunity to participate in the diagnosis and treatment of commonly encountered medical conditions. Appropriate management of these conditions may include pharmacotherapy and/or nonpharmacologic interventions, such as osteopathic manipulative treatment (OMT). Opportunities may exist to expand the utilization of OMT in the management of common conditions, particularly for geriatric patients, who are at increased risk for adverse outcomes from pharmacologic treatments.

Objectives
This study aimed to assess the most common diagnoses and corresponding treatments logged by osteopathic medical students within an ambulatory geriatric population.

Methods
Patient encounters logged electronically by osteopathic medical students were retrospectively reviewed to determine the most commonly reported diagnostic codes and their treatments. Logged interventions were filtered to include patients over the age of 65 years who were seen on family medicine rotations within an ambulatory setting. The top 10 diagnoses were sorted and assessed to determine the associated treatments, including medications, procedures, and OMT.

Results
Between January 2018 and June 2020, a total of 11,185 primary diagnoses were logged pertaining to the defined patient population. The most frequently documented diagnoses were essential hypertension (n=1,420; 12.7 %), encounter for well examination (n=1,144; 10.2 %), type 2 diabetes mellitus (n=837; 7.5 %), hyperlipidemia (n=346; 3.1 %), chronic obstructive pulmonary disease (COPD; n=278; 2.5 %), osteoarthritis (OA; n=221; 2.0 %), low back pain (LBP; n=202; 1.8 %), pain in joint (n=187; 1.7 %), hypothyroidism (n=164; 1.5 %), and urinary tract infections (n=160; 1.4 %). Three of the top 10 logged diagnoses were musculoskeletal in nature (OA, LBP, and pain in joint). Pharmacotherapy was reported as the predominant treatment for musculoskeletal conditions, with OMT being logged as a treatment for 10.9 % (n=50) of those cases. The most commonly logged medication class in the management of patients with those musculoskeletal conditions was nonsteroidal anti-inflammatory drugs (NSAIDs; n=128; 27.9 %), while opioids were the second most frequently documented class of medications (n=65; 14.2 %).

Conclusions
Musculoskeletal complaints were commonly logged by osteopathic medical students within the studied population. Opioids were documented as a treatment for musculoskeletal conditions more frequently than OMT. As such, opportunities exist to expand the utilization of OMT during clinical clerkships and to decrease the frequency of prescribed medications for pain management.
From location to conjunction, disjunction, partition, exemplification and association: Hebrew bein constructions
Authors: Bardenstein Ruti , Ariel Mira 
Published: April 2024

Abstract
Analyzing the diachrony of Hebrew bein, originally a spatial preposition ‘within/among’, this article traces several grammaticization clines associated with bein’s gradual evolution into a rich variety of functions within various constructions. While its early function is purely locative, bein later participates in an array of constructions and sub-constructions, where its syntactic status, its semantic meanings and functions, as well as its discourse role, have shifted considerably. Bein may thus be part of a conjunctive or a disjunctive construction, but it may also be part of an ‘in any case’ adverbial, and later an ‘anyway’ discourse marker. It conveys different locative construals (‘within’, ‘among’ and ‘between’), but also various abstract symmetric relations, such as ‘difference’, ‘dispute’ and ‘separation’. Some bein constructions partition a set, focusing on a subset of it, while in other cases bein serves as an ‘all-purpose’ preposition. Nevertheless, our goal is to show how each grammatical, semantic and discoursal phase is well motivated, given the previous phase. Based on written historical corpora, from Biblical to contemporary Hebrew, we provide a step-by-step diachronic development from earlier to later bein functions.

Abstract
Platinum diselenide (PtSe2), classified as a noble metal dichalcogenide, has garnered substantial interest owing to its layer-dependent band structure, remarkable air-stability, and high charge-carrier mobilities. These properties make it highly promising for a wide array of applications in next-generation electronic and optoelectronic devices, as well as sensors. Additionally, two-dimensional (2D) PtSe2 demonstrates significant potential as a saturable absorber due to its exceptional nonlinear optical response across an ultrabroad spectra range, presenting exciting opportunities in ultrafast and nonlinear photonics. In this work, we explore the second-order nonlinear optical characteristics of 2D PtSe2 by analyzing its second-harmonic generation (SHG) excited by a pulsed laser at 1064 nm. Our investigation unveils a layer-dependent SHG response in PtSe2, with prominent SHG intensity observed in few-layer PtSe2. The distinct six-fold polarization dependence pattern observed in the SHG intensity reflects the inherent threefold rotational symmetry inherent to the PtSe2 crystal structure. Remarkably, the SHG intensity of 4-layer PtSe2 surpasses that of mechanically exfoliated monolayer molybdenum disulfide (MoS2) by approximately two orders of magnitude (60-fold), underscoring its exceptional second-order nonlinear optical response. Combined with its ultrahigh air-stability, these distinctive nonlinear optical characteristics position two-dimensional PtSe2 as a promising candidate for ultrathin nonlinear nanophotonic devices.

Abstract
Glioblastoma (GBM) is one of the most aggressive and hard to treat cancers. Traditional anti-cancer treatment methods have low efficiency and the lifespan after diagnosis is only 12–18 months. Brain tumor cells overexpress many proteins that play an important role in tumor progression and can be used as therapeutic targets. One of the promising approaches in cancer treatment is down-regulation of an extracellular matrix glycoprotein – Tenascin-C (TN-C) through RNA interference therapy. However, the effective delivery of double stranded RNA with one strand complementary to TN-C mRNA sequence is difficult due to rapid degradation by nucleases and low intracellular uptake. Polydopamine (PDA), a biomimetic polymer characterized by high biocompatibility and simple modification ability, is commonly used in nanobiomedicine to create a drug/gene delivery vehicle. Furthermore, photothermal characteristics of this polymer enable its application in photothermal therapy (PTT), which is a great option for cancer treatment. Here we synthesize PDA nanoparticles (NPs) coated with polyamidoamine dendrimers generation 3.0 (DD3.0) for therapeutic anti-TN-C RNA and doxorubicin delivery. As prepared PDA@DD3.0 NPs are then used in combined drug delivery, gene silencing, and PTT of GBM. The obtained materials are analyzed in terms of physicochemical and photothermal properties as well as their cytotoxicity, using human GBM cells. The results demonstrate that the obtained nanocarriers are effective non-viral vehicle for combined therapeutic approach for killing glioma cells via anti-TN-C RNA delivery and combined chemo-PTT therapy (CT-PTT). The application of PDA@DD3.0 NPs contributed to the 3-fold reduction in the proliferation rate of GBM cells, a decrease in the level of TN-C expression (by 30%) and a reduction in the number of viable cells by up to 20%.

Abstract
Improving rice production by increasing the efficiency of rice farming becomes the alternative strategy in Java Island, where half of the Indonesian populations live. Even though some areas are flood-prone, East Java Province is one of the leading rice producers in Indonesia. This study aims to estimate the level of technical efficiency in rice farming in flood-prone areas in East Java and some socio-economic factors that influence the efficiency. The efficiency of rice farming in this study was analyzed using a stochastic frontier production function approach. The results showed that rice farming in flood-prone areas in East Java has been efficient, with an average efficiency of 76.05%. The estimated parameters of farm size, labor, seed, urea fertilizer, and ZA fertilizer are positively significant to rice production, while tractor use is negatively significant to rice production. In addition, farm size, age of household head (HH), education of HH, land ownership, and off-farm jobs positively influence the efficiency of rice farming.

El cuerpo como manifestación holística: Trabajar desde el cuerpo en la educación
Authors: Villanueva Padilla Marta 
Published: April 2024

El tema principal del texto es mostrar la visión que tiene la educación sobre el cuerpo, limitándose a aspectos técnicos y tácticos mientras se ignora todo lo que supone el cuerpo como integración de todas las capacidades humanas. Se pretende dar visibilidad a actividades creativas y artísticas que, a través de la utilización del propio cuerpo y del movimiento, se pueda rentabilizar el proceso de enseñanza-aprendizaje del alumnado de Educación Primaria. Trabajar a través de la integración del cuerpo supone la adquisición de aprendizajes significativos que ayudan a la desinhibición y expresión con total desenvoltura y autonomía de los discentes, permitiéndoles socializar con el resto de la comunidad educativa y con otras personas.
Desde esta perspectiva, se presenta un estudio de casos que tratan la Biodanza en el periodo de Educación Primaria, mostrando los beneficios y ventajas que supone la implantación de actividades artísticas, a través del propio cuerpo, en la educación y el aprendizaje del alumnado. Además, se contribuye de manera directa y de forma positiva, a la salud y bienestar de las personas que llevan a cabo esta disciplina emergente.
LA VIDEOCREACIÓN COMO REPRESENTACIÓN DE LA IDENTIDAD FRACTALIZADA.
Authors: Ortega Rodríguez Shaula 
Published: April 2024

El presente artículo trata sobre el análisis de la videocreación “Fractalidad desfragmentada” realizada a partir de la conceptualización y experimentación de nuevos lenguajes narrativos a modo de collage audiovisual. El planteamiento de la temática parte de las diferentes problemáticas basadas en la construcción de la identidad femenina influenciada por la cultura imperante y enfocada desde un paradigma crítico creativo. Para ello se plantea una investigación basada en la propia práctica artística como fundamento de la construcción de nuestro conocimiento.
El tratamiento del proyecto tiene una doble perspectiva semiótica construida a partir de metáforas y otros recursos retóricos a fin de evidenciar la influencia de las estructuras sociales en la construcción de la identidad. Como menciona Jose Luis Brea (2.007) los ojos no perciben todo lo que hay en una imagen aunque llega de manera inconsciente a nuestro cerebro, por ello por una parte, el paralelismo simbólico es concebido desde una perspectiva que no es evidente, como como ocurre con el desarrollo del propio proceso de creación y la elaboración técnica de toda obra artística, donde la estructura del montaje y el uso del apropiacionismo de imágenes sin ser visibles, apoya y fundamenta conceptualmente del segundo enfoque significativo del contenido temático.
