Abstract
This research is dedicated to investigating the antioxidant potential and phytochemical composition of three distinct extracts derived from Vitex agnus-castus L. These extracts, prepared through aqueous (EXA), ethanolic (EXE), and methanolic (EXM) maceration, were chosen based on prior assessments of total polyphenol content in extracts obtained from five solvents with differing polarities: water, methanol, ethanol, acetone, and butanol. The study initiated with a comprehensive phytochemical analysis focusing on the determination of total polyphenols and flavonoids. The quantification of total polyphenols was carried out using the Folin–Ciocalteu method, while the AlCl3 method was employed to assess flavonoids. In evaluating the in vitro antioxidant activity, we employed two well-established methods, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric-reducing antioxidant power (FRAP). The preliminary tests, gauging the efficacy of solvents, demonstrated that the order of optimal solvent selection was as follows: aqueous, methanolic, ethanolic, butanolic, and acetone. Consequently, the first three solvents were chosen for the preparation of the extracts. The phytochemical analysis unveiled that EXA exhibited the highest total polyphenol content, with an impressive value of 126.84 ± 1.24 mg EAG/g extract, whereas EXE exhibited the lowest concentration of total polyphenols, measuring at 117.26 ± 0.18 mg EAG/g extract. In contrast, EXM showcased a notably high flavonoid content, registering at 33.65 ± 1.04 mg EQ/g extract, while EXA displayed a comparatively lower flavonoid content at 14.93 ± 0.14 mg EQ/g extract. When assessing antioxidant properties, EXA emerged as the most potent against both DPPH and FRAP, recording values of 78.94 ± 1.84 and 203.27 ± 0.17 μg/ml, respectively. In contrast, the ethanolic extract exhibited relatively lower antioxidant activity, with values of 204.16 ± 1.87 μg/ml for DPPH and 307.10 ± 1.15 μg/ml for FRAP.
Lexical systems with systematic gaps: verbs of falling

Published: January 2024

Abstract
The paper contributes to the typology of encoding motion events by highlighting the role of the verbal root meaning in lexicalization of motion. We focus on lexical semantics of the verbs of falling, which we study on a sample of 42 languages using the frame-based approach to lexical typology. We show that, along with downward motion, the verbs of falling regularly denote adjacent situations; and vice versa, the idea of downward motion is systematically conveyed by verbs from adjacent semantic fields. These findings challenge the application of the classical parameters of motion events (e.g. Path) to any given motion event description and offer new insights into the understanding of lexicalization patterns in general.
Practical implications in the interpolation methods for constructing the regional mean sea surface model in the eastern Mediterranean Sea

Published: January 2024

AbstractThis investigation estimates a regional Mean Sea Surface (MSS) model, named SY21MSS, over the eastern Mediterranean Sea using satellite altimetry data from nine Exact Repeat Missions (ERM) and two Geodetic Missions (GM). Two interpolation methods, Least Squares Collocation (LSC) and Ordinary Kriging (OK), were employed, and statistical metrics were applied to assess their performance within a 15 km buffer from the coast. The comparison between LSC and OK techniques in the context of regional MSS modeling primarily centers on the covariance functions used by these methods. Furthermore, generalized cross-validation results indicate that OK outperforms LSC in this region. Consequently, the study recommends adopting the Kriging-based model for calculating regional MSS models in this region due to its superior performance. The investigation further explored the disparities between estimated regional MSS models and the global model DTU18MSS, highlighting a pronounced similarity between OK-SY21MSS and DTU18MSS, as evidenced by a lesser standard deviation (SD) difference compared to LSC-SY21MSS. The practical implications of this research underscore the importance of selecting an appropriate interpolation technique based on data characteristics and study area specifics. While both LSC and OK techniques are deemed viable for MSS modeling, the study emphasizes the superior performance of OK, particularly concerning covariance functions. Additionally, the results emphasize caution when applying global models in regions with significant local variations.

Published: January 2024

Abstract
In the maritime environment, multipath interference exhibits a significantly pronounced influence, resulting in GNSS system performance degradation. Enhancing system performance involves the identification and elimination of NLOS signals. This study focuses on the analysis of multipath data induced by sea waves, collected off the coast of Kakinada Sea (16.98° N, 82.29° E), to categorize signals as Line-of-Sight (LOS), Non-Line-of-Sight (NLOS) and Multipath (MP). A machine learning (ML) approach is employed to identify the presence of LOS, NLOS and MP signals in a coastal environment, both before and after the advancement of tidal waves. In the proposed approach, ML algorithms are trained using 3 key parameters namely elevation angle, signal strength and pseudorange residuals. This study involves the implementation of 14 prominent supervised classification algorithms and their accuracies and computational times are compared. The results due to GPS (L1) and IRNSS (L5 and S1) are considered. Decision Tree and its ensemble function AdaBoost, exhibited exceptional performance of accuracy (99.99 %) and computational time (0.45 s).

Abstract
Optical control is achieved on the excited state energy transfer between spatially separated donor and acceptor molecules, both coupled to the same optical mode of a cavity. The energy transfer occurs through the formed hybrid polaritons and can be switched on and off by means of ultraviolet and visible light. The control mechanism relies on a photochromic component used as donor, whose absorption and emission properties can be varied reversibly through light irradiation, whereas in-cavity hybridization with acceptors through polariton states enables a 6-fold enhancement of acceptor/donor contribution to the emission intensity with respect to a reference multilayer. These results pave the way for synthesizing effective gating systems for the transport of energy by light, relevant for light-harvesting and light-emitting devices, and for photovoltaic cells.

Published: January 2024

Abstract
Metasurface holograms offer various advantages, including wide viewing angle, small volume, and high resolution. However, full-color animation of high-resolution images has been a challenging issue. In this study, a full-color dielectric metasurface holographic movie with a resolution of 2322 × 2322 was achieved by spatiotemporally multiplexing 30 frames with blue, green, and red color channels at the wavelengths of 445 nm, 532 nm, and 633 nm at the maximum reconstruction speed of 55.9 frames per second. The high average transmittance and diffraction efficiency of 92.0 % and 72.7 %, respectively, in the visible range, were achieved by adopting polarization-independent silicon nitride waveguide meta-atoms, resulting in high color reproducibility. The superposition of three wavelengths was achieved by adjusting the resolutions and positions of target images for each wavelength while maintaining the meta-atom pitch constant. The improvement in diffraction efficiency was brought about by the optimization of etching conditions to form high-aspect vertical nanopillar structures.

Abstract

Objectives
Vigorous discussions are ongoing about future efficacy trial designs of candidate human immunodeficiency virus (HIV) prevention interventions. The study design challenges of HIV prevention interventions are considerable given rapid evolution of the prevention landscape and evidence of multiple modalities of highly effective products; future trials will likely be ‘active-controlled’, i.e., not include a placebo arm. Thus, novel design approaches are needed to accurately assess new interventions against these highly effective active controls.

Methods
To discuss active control design challenges and identify solutions, an initial virtual workshop series was hosted and supported by the International AIDS Enterprise (October 2020-March 2021). Subsequent symposia discussions continue to advance these efforts. As the non-inferiority design is an important conceptual reference design for guiding active control trials, we adopt several of its principles in our proposed design approaches.

Results
We discuss six potential study design approaches for formally evaluating absolute prevention efficacy given data from an active-controlled HIV prevention trial including using data from: 1) a registrational cohort, 2) recency assays, 3) an external trial placebo arm, 4) a biomarker of HIV incidence/exposure, 5) an anti-retroviral drug concentration as a mediator of prevention efficacy, and 6) immune biomarkers as a mediator of prevention efficacy.

Conclusions
Our understanding of these proposed novel approaches to future trial designs remains incomplete and there are many future statistical research needs. Yet, each of these approaches, within the context of an active-controlled trial, have the potential to yield reliable evidence of efficacy for future biomedical interventions.

Published: January 2024

This paper will fulfill two purposes:
A) To describe ways, means, and advantages of using computers to analyse two-dimensional clinical data (e.g. photographs, charts) so that the reader will have a clearer understanding of these methods and perhaps start considering applying them in practice.
B) To present the results from a study of the central visual fields of 129 normal patients aged 10 to 70 years. These results are presented as average central fields for indivi­dual age groups ( 15, 25, 35, 45, 55, 65 years) so that the reader may compare a given patient's central field data to a norm for that patient's age group.
Corneal Vascularization in a Group of Soft Contact Lens Wearers: Prevalence, Magnitude, Type and Related Factors
Authors: Jantzi J.D , Jackson W.E. , Smith K.M 
Published: January 2024

Groups of 827 soft contact lens wearers and 900 non-contact lens wearers were examined for corneal vascularization by means of biomicroscopy. Slit-lamp photo­graphs were taken to record cases of vascularization and to permit measurements of the magnitude of the vascular response. The prevalence of corneal vasculariza­tion in the soft contact lens group was 33.9% compared to 2.0% in the non-contact lens group.
Of the soft contact lens related vascular responses, 98.6% were located in the superficial stroma, indicating that the conjunctival circulation is most often involved in cor­neal vascular responses to soft contact lenses. Vascular penetration radially into the cornea from the limbus did not exceed 4.5 mm in either the study or control groups; 96.8% of the vascular responses being 1.5 mm or less in the soft contact lens group. Age and sex of the patients were not significantly related to the observed frequency of corneal vascularization in either the study or control groups. However, refractive error, daily wearing time and the total length of time soft contact lenses had been worn were significantly related to the observed frequency of corneal vas­cularization in the soft contact lens group.
Even though sampling error and bias affect this type of study, it appears that corneal vascularization is a frequent ocular response in patients who are wearing daily-wear and extended-wear soft contact lenses. This study supports the recom­mendation that all soft contact lens patients, including those who may be asympto­matic, should be carefully examined at regular intervals for signs of adverse ocular responses such as corneal vascularization.
The Study of Translation Ideology and Its Accuracy in Qur'anic Vocabulary for Women
Authors: Syihabuddin Syihabuddin , Aryanti Tutin 
Published: January 2024

Gender issues have garnered considerable attention from researchers, women's campaigners, and society at large. The perspectives held by individuals are grounded on cultural, religious, and ideological frameworks. The religious perspectives, such as those rooted in Islam, draw upon the Qur’an and its translation as primary source. The comprehension of translation is purportedly intricately linked to the underlying ideology that informs the translation process. This study aimed to offer a formulation of ideology that may be utilized to sustain the notion of gender as shown in the translated text. In order to accomplish this objective, an analysis was conducted on the translation of Quranic verses that encompass words pertaining to women, specifically al-umm, al-wālidah, az-zauj, al-'imra`ah, an-nisa`, an-niswah, and al-untsa, employing a series of steps. Those steps were examining the translation technique, identifying the underlying ideology associated with the technique, evaluating the accuracy of the conveyed meaning, engaging in a discussion, and formulating a conclusion. Moreover, this study included the cumulative sum of the seven terms amounted to 146 units, which were extracted from The Qur’an and Its Translation as published by the Ministry of Religion. The findings of this study indicate that gender concepts are translated in a literal manner. This approach demonstrates the adoption of the foreignization ideology in translation, which prioritizes the source language and the precise conveyance of its meaning. The utilization of the idea is further reinforced by the assertion that the seven terms are faithfully translated, except for the term imra'ah, which is rendered as wife, a translation that is deemed to be inaccurate.

OBJECTIVES
To identify independent predictors of and derive a risk score for acute hematogenous osteomyelitis (AHO) in children.

METHODS
We conducted a retrospective matched case-control study of children &gt;90 days to &lt;18 years of age undergoing evaluation for a suspected musculoskeletal (MSK) infection from 2017 to 2019 at 23 pediatric emergency departments (EDs) affiliated with the Pediatric Emergency Medicine Collaborative Research Committee. Cases were identified by diagnosis codes and confirmed by chart review to meet accepted diagnostic criteria for AHO. Controls included patients who underwent laboratory and imaging tests to evaluate for a suspected MSK infection and received an alternate final diagnosis.

RESULTS
We identified 1135 cases of AHO matched to 2270 controls. Multivariable logistic regression identified 10 clinical and laboratory factors independently associated with AHO. We derived a 4-point risk score for AHO using (1) duration of illness &gt;3 days, (2) history of fever or highest ED temperature ≥38°C, (3) C-reactive protein &gt;2.0 mg/dL, and (4) erythrocyte sedimentation rate &gt;25 mm per hour (area under the curve: 0.892, 95% confidence interval [CI]: 0.881 to 0.901). Choosing to pursue definitive diagnostics for AHO when 3 or more factors are present maximizes diagnostic accuracy at 84% (95% CI: 82% to 85%), whereas children with 0 factors present are highly unlikely to have AHO (sensitivity: 0.99, 95% CI: 0.98 to 1.00).

CONCLUSIONS
We identified 10 predictors for AHO in children undergoing evaluation for a suspected MSK infection in the pediatric ED and derived a novel 4-point risk score to guide clinical decision-making.

Diurnal Chorusing in Nine Species of North American Anurans
Authors: MCCALLUM MALCOLM 
Published: January 2024

A year-long survey of survey of diurnal frog calling behavior was conducted at the Red River Research and Education Park in Shreveport (Caddo Parish), Louisiana to investigate the prevalence of daytime breeding choruses in the species present at the park. We determined that 60% (9/15) of species known from the area participated in daytime breeding choruses. Four of these were new species reports for the behavior. One species was identified entirely based on a daytime chorus from outside the normal breeding season. Although we believe daytime chorusing is widespread in frogs, several species did not diurnally chorus during our study. Diurnal calling may be an important indicator of the peak breeding season for a species and it may also be a useful tool at times when night surveys are impossible.
