A Performance Indicator for Optimizing Source–Detector Separation in Functional Near‐Infrared Spectroscopy

open access: yesInternational Journal of Imaging Systems and Technology, Volume 35, Issue 4, July 2025.
ABSTRACT The performance of Functional Near‐Infrared Spectroscopy (fNIRS) devices critically depends on the probe design, which affects signal quality, spatial and depth resolution, and data reliability. A critical component of probe separation is source‐to‐detector separation, which is defined as the distance between the light source and the detector.

Stochastic Differential Equation Approach as Uncertainty‐Aware Feature Recalibration Module in Image Classification

open access: yesInternational Journal of Imaging Systems and Technology, Volume 35, Issue 4, July 2025.
ABSTRACT Despite significant advancements in image classification, deep learning models struggle to accurately discern fine details in images, producing overly confident and imbalanced predictions for certain classes. These models typically employ feature recalibration techniques but do not account for the underlying uncertainty in predictions ...

What if I fail? Examining the association between avoidance motivation and research career intentions

open access: yesThe Career Development Quarterly, Volume 73, Issue 2, Page 80-91, June 2025.
Abstract This study investigated how avoidance motivation, which entails a fear of failure and focus on avoiding negative outcomes, influences adolescents’ aspirations toward scientific research careers. Participants consisted of 245 high school students participating in a summer science enrichment program. Results of a hierarchical regression analysis

Microclimate Refugia Are Transient in Stable Old Forests, Pacific Northwest, USA

open access: yesAGU Advances, Volume 6, Issue 3, June 2025.
Abstract An issue of global concern is how climate change forcing is transmitted to ecosystems. Forest ecosystems in mountain landscapes may demonstrate buffering and perhaps decoupling of long‐term rates of temperature change, because vegetation, topography, and local winds (e.g., cold air pooling) influence temperature and potentially create ...
