Article Abstract
Selective laser sintering (SLS) is an efficient process in additive manufacturing that enables rapid part production from computer-based designs. However, SLS is limited by its notable lack of in-situ process monitoring when compared to other manufacturing processes. We report the incorporation of optical coherence tomography into an SLS system in detail and demonstrate access to surface and sub-surface features. Video frame rate cross-sectional imaging reveals areas of sintering uniformity and areas of excessive heat error with high temporal resolution. We propose a set of image processing techniques for SLS process monitoring with OCT and report the limitations and obstacles for further OCT integration with SLS systems.

The influence of lighting environment in extra-long tunnels and its psychological impact on young drivers: evidence from virtual driving simulations.
Traffic Inj Prev
September 2025
Chongqing Jianzhu College, Chongqing, P.R. China.
Purpose: The monotonous lighting environment in extra-long tunnels often induces mind-wandering in drivers. To address this issue, this study explores effective strategies to optimize tunnel lighting environments by configuring various background colors and special lighting zones to enhance the alertness of young drivers and ensure driving safety.
Methods: A virtual driving simulator was utilized to carry out the experiment.

Continuous monitoring of cardiovascular vital signs can reduce the incidence and mortality of cardiovascular diseases, yet cannot be implemented by current technologies because of device bulkiness and rigidity. Here, we report self-adhesive and skin-conformal ultrasonic transducer arrays that enable wearable monitoring of multiple hemodynamic parameters without interfering with daily activities. A skin-adaptive focused ultrasound method with rational array design is proposed to implement measurement under wide ranges of skin curvatures and depths with improved sensing performances.

NIHR Biomedical Research Centre at Moorfields Eye Hospital NHS Foundation Trust and Institute of Ophthalmology University College London, London, United Kingdom.
Objectives: To describe the research principles and cohort characteristics of the multi-disciplinary Project HERCULES, an innovative model of safe high-volume outpatient eye-care service for patients with stable chronic eye diseases. Results and analyses of the workstreams within Project HERCULES will be reported elsewhere. The rationale was to improve eye-care capacity in the National Health Service (NHS) in England through the creation of technician-delivered monitoring in a large retail-unit in a London shopping-centre, with remote asynchronous review of results by clinicians (named Eye-Testing and Review through Asynchronous Clinic (Eye-TRAC)).

Background: Underwater environments face challenges with image degradation due to light absorption and scattering, resulting in blurring, reduced contrast, and color distortion. This significantly impacts underwater exploration and environmental monitoring, necessitating advanced algorithms for effective enhancement.
Objectives: The study aims to develop an innovative underwater image enhancement algorithm that integrates physical models with deep learning to improve visual quality and surpass existing methods in performance metrics.
Gaps in care across the cancer screening continuum for cervical, colorectal and lung cancer.

Background: While screening for cervical, colorectal, and lung cancers reduce cancer-specific mortality, the full benefits of screening are only realized when coupled with timely care across the subsequent "screening continuum" steps, including surveillance (results warranting frequent monitoring), diagnostic evaluation (results that require additional testing), and treatment (detected cancers). Our goal was to describe the proportion of individuals receiving timely cervical, colorectal, and lung cancer care at each step in the screening continuum.
Methods: This retrospective cohort study used data from the 10 health care settings that participate in the Population-based Research to Optimize the Screening Process (PROSPR II) consortium and included individuals who were eligible for a step along the cancer screening continuum in 2018.
