Low-cost geometry-tunable PDMS intraocular lenses fabricated using LCD 3D-printed molds for canine ophthalmic applications

This study demonstrates the feasibility of fabricating geometry-tunable polydimethylsiloxane (PDMS) intraocular lens (IOL) prototypes using consumer-grade liquid crystal display (LCD) 3D-printed molds and PDMS casting. A reusable mold fabrication strategy incorporating a PMMA bar...

Updating the Fundamentals: Forecasting the 2026 Midterm Election Post-Gallup

Statistical forecasts of congressional and presidential elections have become a regular feature of our discipline, and most rely on presidential approval, which has historically been provided by the polling firm Gallup.In 2025, Gallup discontinued its monthly presidential approva...

The expanding landscape of adult stem cell niches

Adult stem cells reside within specialized niches that provide the local instructions needed to sustain regenerative fitness. Since the recognition that stem cells are not autonomous, the concept of the niche has widened from a local collection of supportive cells into a landscap...

Scope of Practice in American mountain guiding

This study explored the implications of the American Mountain Guides Association's (AMGA) adoption of a new Scope of Practice (SOP) framework for affiliated mountain guiding professionals in the United States. The researchers used an interpretivist methodological approach to asse...

Volatile-element depletion in rocky planets as a purity spectrum of a single information field: An information-dynamics reinterpretation of hybrid accretion

Wang et al. (2026, Nature Astronomy) showed that the moderately-volatile lithophile element (MVLE) depletion patterns of Earth and Mars record different formation pathways: Earth accreted ≳75% of its mass via pebble accretion, Mars ∼73% via collisions of volatile-depleted planete...

Bridging accuracy and interpretability in predictive learning analytics: A human-centered grey-box approach

Learning analytics has been increasingly using predictive models to support educational decision-making. However, the trade-off between predictive accuracy and interpretability remains a central challenge that limits how these models can be understood and used by educators. This...

Why they come (back): Motive clusters of seasonal employees and their multiple workplace commitments

This study develops seasonal employee typologies for the Alpine tourism and hospitality sector by connecting motives for seasonal work with varying levels of different workplace commitments and return intention. Conceptualizing the destination as an analytical lens rather than me...

RT-ProtoNet: radiative-transfer-guided few-shot prototype networks for cross-region bathymetry in optically clear reef environments

Satellite-derived bathymetry faces two coupled obstacles: labels are scarce, and models transfer poorly across regions. We propose RT-ProtoNet, a radiative-transfer-guided few-shot prototype network, which takes patches from three penetrating Sentinel-2 bands and treats ICESat-2...

Dryland-to-paddy conversion enhances hydrological functioning by reshaping soil structure in the hilly red soil region of southern China

Soil organic carbon (SOC) and soil structure are key determinants of soil hydraulic properties. However, the roles of SOC fractions and soil structure in regulating hydraulic behavior during dryland (DL) conversion to paddy fields (PF) in the hilly red soil region of southern Chi...

Post-Fall Non-Recovery State Detection Using Pose Estimation and Temporal Persistence

This paper presents an edge-based system for detecting post-fall non-recovery states in a predefined indoor monitoring area. The target of the proposed system is not the instantaneous fall event itself, but a fall-like abnormal posture that persists without recovery. Human keypoi...

A Study on CFD-based Manoeuvring Performance Analysis of Ships equipped with Azimuth Thrusters

With the increasing use of azimuth thrusters in LNG bunkering vessels, concerns have arisen regarding the influence of duct side area variation on manoeuvring performance. In practice, simplified stock azimuth thruster models without geometric similarity are widely adopted in mod...

An Electrical Safety Framework Linking Pre-use Inspection, Periodic Inspection, and Detailed Safety Checks for ESS Equipped with Grid-Forming PCS

As renewable energy and inverter-based resources expand, voltage and frequency support is shifting from synchronous machines to power-electronic resources. Battery ESS power conversion systems are thus evolving into key assets for grid support, islanded operation, and system rest...

Perspectives on Community-Based Pediatric Obesity Prevention and Management Programs in South Korea: A Qualitative Interview Study of School and Local Public Health Center Providers

Background: Pediatric obesity has increased globally, and South Korea has reported the highest prevalence in East Asia. Despite national policies addressing children's nutrition and health, fragmented governance and overlapping programs may limit their effectiveness. We compared...

Development of a Towing System Design Program Based on the U.S. Navy Towing Manual

Marine towing is required for transporting ships and floating structures and for salvage operations of damaged vessels. Safe towing operations require the estimation of towing resistance, selection of an appropriate tug and towing equipment, and verification of the towing system....

Diode-Clamped Three-Level Interleaved LLC Resonant Converter for Reducing Input Current Ripple and Switch Voltage Stress

This paper proposes a novel diode-clamped three-level interleaved double LLC resonant converter for reducing input current ripple and switch voltage stress in high-voltage DC applications. The proposed converter utilizes a three-level structure with a diode-capacitor clamping cir...

Long-Term Economic Analysis of an ESS Leasing-Based Virtual Power Plant Business Model for Participation in Renewable Energy Bidding Markets

Virtual power plant (VPP) operators participate in renewable energy bidding markets by forecasting renewable generation and submitting bids based on these forecasts. As allowable forecast-error ranges have recently been tightened to improve the reliability of renewable energy res...

When digital meets green: How technological convergence drives eco-innovation in Chinese firms

The convergence of digital and green technologies (DGT) is emerging as a key driver of low-carbon transformation, yet its effects on eco-innovation remain understudied. Using matched micro-enterprise data and highly granular patent data from 2010 to 2023, we employ co-classificat...

The effect of being assigned to special needs assistance depends on children's types of difficulty

This study examines the effects of being assigned to special needs assistance (SNA) and children's difficulty types ( n = 35,024; 1809 received SNA) in early childhood education and care (ECEC) on children's language and academic skills in primary school. Using the Norwegian Moth...

Fault diagnosis of photovoltaic array under service-cycle degradation evolution via semi-supervised conditional domain adversarial network with dynamic label smoothing

The inevitable performance degradation of photovoltaic modules during long-term service induces a dynamic drift in their output feature distributions over time. However, existing fault diagnosis methods predominantly rely on static datasets acquired from undegraded arrays or thos...

Language-derived mental object load suppresses posterior alpha power

Language and vision are two primary source modalities of information for humans. To uncover shared and unique mental representations across linguistic and visual inputs, one approach is to test the extent to which a certain neural signature is shared. In the current EEG study, we...
