Analysis of Pulsatile Vessel Expansion in Healthy, COPD‐and PH‐Patients Using Dynamic Vessel Segmentation in Free‐Breathing Lung MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The pulsatile expansion of pulmonary vessels carries dynamic cardiopulmonary information that may reveal disease earlier than structural changes alone. Purpose To test (i) intra‐ and inter‐scan repeatability of dynamic vessel metrics in healthy subjects, and (ii) whether chronic obstructive pulmonary disease (COPD) and postcapillary

Are Workplace Friendships Nothing for Older Workers? Decoding the Psychological Mechanisms Linking Age to Workplace Friendship

Journal of Organizational Behavior, EarlyView.
ABSTRACT Given the benefits of workplace friendship, understanding its maintenance is essential. Age is particularly relevant due to the aging and increasingly age‐diverse workforce, yet its relationship with workplace friendship remains unclear, with prior studies reporting positive, negative, or null correlations. As age itself is a proxy for further

I Can't Split Myself in Two (or Five): Job Crafting in Highly Demanding and Interdependent Work Environments

Journal of Organizational Behavior, EarlyView.
ABSTRACT Employees in highly demanding, interdependent work environments face a dilemma: while avoidance‐focused job crafting can preserve their own well‐being, these self‐initiated changes to their jobs could negatively affect coworkers. Drawing on qualitative interviews with 81 employees concurrently working for multiple agile teams in a European ...

Decision Threshold Setting in Binary Classification Problems—A Behavioral Lens

Journal of Operations Management, EarlyView.
ABSTRACT When binary classification models are wrong, managers face misclassification costs. Although false positive outcomes imply unnecessary mitigation efforts, false negative outcomes imply overlooking the class of interest. Humans calibrate these ai models supporting operational systems by adjusting the decision threshold that translates ...

Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

IET Networks, EarlyView., 2023
We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...
