Performance assessment of Laguerre–Gaussian OAM modes for high-capacity underwater optical wireless communication

Abstract In this paper, a four Laguerre–Gaussian modes ( LG 0 0 ${\mathit{LG}}_{0}^{0}$ , LG 18 0 ${\mathit{LG}}_{18}^{0}$ , LG 45 0 ${\mathit{LG}}_{45}^{0}$ , and LG 75 0 ${\mathit{LG}}_{75}^{0}$ ) based underwater optical wireless communication (UOWC) system for transporting 10...

Adaptive Tracking Control for Underactuated Lunar Hopping Vehicles

This paper develops two different adaptive control solutions for a propulsive exploration lunar hopping vehicle along with their performance characterization. Full six-degree-of-freedom error dynamics relative to an a priori defined reference trajectory are outlined for controlle...

Gonioscopy-assisted transluminal trabeculotomy versus trabeculectomy with phacoemulsification in primary open angle glaucoma – One-year outcomes

PURPOSE: To assess the safety and efficacy of gonioscopy-assisted transluminal trabeculotomy (GATT) with phacoemulsification in primary open-angle glaucoma (POAG). METHODS: In this prospective, nonrandomized, comparative study, patients with POAG underwent either phaco-GATT (Grou...

Relations Acting on Relations: A Layered Conjecture Statement with Definitions, Status and Refutation Conditions

The research programme asks whether, in systems whose parts are relations, a relation can act on the update rule of another relation, and whether such second-order structure is functionally indispensable. This statement fixes one core claim, an existence claim (C1), defines its t...

Status and Challenges of Multisectoral Antimicrobial Resistance (AMR) Surveillance in Ethiopia: Leveraging TADAS.net as a Digital Tool

Abstract Antimicrobial resistance (AMR) is a major One Health challenge requiring coordinated surveillance across human, animal, and environmental sectors. Ethiopia’s Antimicrobial Resistance Prevention and Containment Strategic Plan (2021–2025) recognized this need and prioritiz...

Joint extraction of space target micro-motion parameters at low SNR based on consistency variational autoencoder and cascaded transformer

Micro-Doppler technology has significant applications in the recognition of space non-cooperative targets. However, in practical radar detection, background noise caused by low signal-to-noise ratios and the nonlinear coupling among various micro-motion parameters limit the featu...

Short-term outcomes of low-dose versus moderate-dose prednisolone in ocular myasthenia gravis: a retrospective cohort study

Abstract Background The optimal corticosteroid dose for treating ocular myasthenia gravis remains uncertain. Higher doses may increase the risk of adverse effects without providing additional clinical benefit. This study aimed to compare the effectiveness of low-dose versus moder...

Visual and refractive outcomes of Eyecryl phakic intraocular lens in myopia and myopic astigmatism

PURPOSE: To assess the refractive accuracy and safety profile of posterior chamber Eyecryl phakic intraocular lens (pIOL) implantation. SETTING: Tertiary eye care hospital in South India. DESIGN: Retrospective study. METHODS: Patients undergoing posterior chamber Eyecryl pIOL (Bi...

Language Games About Language Games: Wittgensteinian Hermeneutics Between Imaginative Participation and Analysis

ABSTRACT Drawing on Remarks on Frazer's Golden Bough and Philosophical Grammar , it is shown that, from a hermeneutic perspective, the Middle Wittgenstein, develops a fluid model of understanding which supposes a fixable meaning of any given text. In this context, to understand a...

Modeling of Surface Tension Isotherms with an Extremum for Binary Liquid Mixtures

Abstract Anomalous (or aneotropic) surface tension (σ) isotherms with a distinct extremum (minimum or maximum) have been reported for numerous binary liquid mixtures, yet a feasible model for describing such aneotropic behavior remains lacking. In this work, by coupling the surfa...

Number of natural teeth and incident cognitive impairment in older Chinese adults

This study aimed to examine the longitudinal association between baseline number of natural teeth and incident cognitive impairment among older Chinese adults in the Chinese Longitudinal Healthy Longevity Survey and explore whether dietary diversity partially mediated this associ...

Acute colonic variceal bleeding treated with coil-assisted retrograde transvenous obliteration following atezolizumab–bevacizumab therapy for advanced hepatocellular carcinoma

Rationale: Colonic variceal bleeding is a rare but potentially life-threatening manifestation of portal hypertension. Bevacizumab therapy is associated with an increased risk of variceal bleeding, but bleeding from ectopic varices is less well recognized. Patient concerns: A 66-y...

Enabling Aqueous Ozonation via Ozone Nanobubbles: Oxidative Modification of Activated Carbon and Its Performance and Economic Implications

Abstract Traditional adsorbent functionalization often relies on energy-intensive thermal oxidation or hazardous chemical reagents, hindering sustainable wastewater treatment infrastructure. This study introduces ozone nanobubbles (O3NBs) as a transformative, environmentally beni...

Patient Blood Management Adoption and Transfusion-Threshold Concordance Among Romanian Anesthesiologists: National Survey Analysis

Abstract Background Romania issued national patient blood management (PBM) guidelines in 2018. A 2023 national survey described the overall uptake of PBM among anesthesiologists but did not examine which clinicians and institutions adopted PBM, nor whether stated transfusion thre...

Conservative Management of Partial Achilles Tendon Rupture in a Professional Soccer Player: A Case Report

BACKGROUND: Partial Achilles tendon ruptures in elite soccer are uncommon and optimal management remains controversial. Evidence guiding rehabilitation is limited. CASE PRESENTATION: A 23-year-old professional soccer player experienced a 50% tear of the left Achilles tendon durin...

Third-Harmonic Generation in Crumpled Silicon Nanomembranes

Abstract Silicon nanomembranes provide mechanically compliant devices for strain engineering. Here, we investigate third-harmonic generation in flat and crumpled silicon nanomembranes of 15 and 35 nm using polarization-resolved third-harmonic generation microscopy with ab initio...

Maize STEM BENDING1 controls plant architecture through cell wall and auxin pathways

Abstract Crop yield is largely determined by plant architecture. Identifying the key genes responsible for maize architecture can help optimize plant architecture for high-density planting. Here, we characterized a dominant stem bending mutant ( Stb1 ) in maize, which exhibited b...

Advanced airway management practice patterns and short-term survival in Poland’s national physician-staffed helicopter emergency medical service, 2020–2024: a retrospective observational study

Advanced prehospital airway management involves endotracheal intubation or supraglottic airway placement. Evidence on airway management and survival in combined ground EMS–HEMS care remains limited, particularly regarding technique sequence and outcomes across clinical groups. Th...
