A Novel Slit Lamp‐Based System for 3D Ultrasound of the Eye

Journal of Ultrasound in Medicine, EarlyView.
Objectives This study aims to develop and evaluate a novel slit‐lamp‐based system to acquire 3‐dimensional (3D) ultrasound volumes using conventional ultrasound probes. Methods A slit‐lamp adapter was 3D printed and connected with a linear actuator and graphical user interface (GUI) system to control movement and create volumes of 2‐dimensional scans ...

Ultra Short Pulse Laser Welding of Glass to Metal in the Low Fluence Regime

Laser &Photonics Reviews, EarlyView.
Ultrashortpulse laser welding enables precise joining of glass and metal with minimal thermal damage. We introduce the TwoThresholds Criteria to identify suitable laser parameters by combining the nonlinearabsorption threshold in glass with the metalmodification fluence threshold.

Development of a Fiber Bundle Cell Framework for Rapid, Reliability‐Based Analysis and Design of Pseudo‐Ductile Thin‐Ply Hybrid Composites

Polymer Composites, EarlyView.
Application of the fiber bundle cell model for design or prediction of pseudo‐ductility. ABSTRACT In this study, we developed and validated a novel fiber bundle cell (FBC) framework to enable rapid, reliability‐anchored design of pseudo‐ductile thin‐ply carbon/glass hybrid composites.

On the Mechanical and Thermal Behavior of PLA, PBAT, and PHBV‐Based Ternary Blends and the Effect of Short Flax Fibers as Reinforcing Agents

Polymer Composites, EarlyView.
Preparation and testing of biodegradable polymer ternary blends and composites with short flax fibres. ABSTRACT Bioplastics offer environmental benefits but they are costly and exhibit lower mechanical and thermal performance compared to fossil‐based counterparts. Poly(butylene adipate‐co‐terephthalate) (PBAT) exhibits high ductility but relatively low

Recycling‐Induced Changes of Molecular Weight and Structural Properties in PET Monopolymer Blends

Journal of Polymer Science, EarlyView.
The present study investigates the molecular weight, thermal, rheological, and mechanical properties of polymer blends of high and low molecular weight polyethylene terephthalate (PET) components. The research reveals that extrusion processing influences chain scission and chain extension, inhibiting the broadening of the molecular weight distribution ...

Hyperspectral species maps and LiDAR‐based structured population models show future forest fire frequency may compromise forest resilience

Remote Sensing in Ecology and Conservation, EarlyView.
Monitoring forest recovery from disturbances at scale requires tracking tree dynamics, yet traditional ground‐based approaches are resource‐intensive. We present a pipeline to parameterize integral projection models (IPMs) using LiDAR data and hyperspectral‐based species maps to assess post‐fire recovery across large, forested areas at the Caribou ...

Carbon‐Intensive Agriculture: Agricultural Trade Openness, Energy Use, and Environmental Challenges in High‐Emission Countries

Sustainable Development, EarlyView.
ABSTRACT This study examines the socioeconomic determinants of agricultural CO2 emissions in the 10 highest‐emitting agricultural economies from 1992 to 2022. Using the LM bootstrap cointegration method and the method of moments quantile regression (MMQR), the analysis identifies long‐run relationships and heterogeneous effects across the emissions ...

Advancing SDG7–SDG13 Through Technology Innovation: The Environmental Impacts of Technological Advancements in Green, Fossil, and Energy Efficiency in Türkiye

Sustainable Development, EarlyView.
ABSTRACT Identifying the principal drivers of carbon emissions is vital for designing effective mitigation strategies and supporting long‐term environmental sustainability. Although previous studies have explored multiple determinants of emissions, limited attention has been paid to the most influential energy–technology channels within trade‐dependent
