Maritime transportation plays a critical role in global containerized cargo logistics, with seaports serving as key nodes in this system. Ports are responsible for container loading and unloading, along with inspection, storage, and timely delivery to the destination, all of which heavily depend on the performance of the container handling equipment (CHE). Inefficient maintenance strategies and unplanned maintenance of the port equipment can lead to operational disruptions, including unexpected delays and long waiting times in the supply chain.

Background: Accurate measurements from cardiovascular magnetic resonance (CMR) images require precise positioning of scan planes and elimination of motion artifacts from arrhythmia or breathing. Unidentified or incorrectly managed artifacts degrade image quality, invalidate clinical measurements, and decrease diagnostic confidence. Currently, radiographers must manually inspect each acquired image to confirm diagnostic quality and decide whether reacquisition or a change in sequences is warranted.

The perception of time is a subjective experience influenced by various factors such as individual psychology, external stimuli, and personal experiences, and it is often assessed with the use of the reproduction task that involves individuals estimating and reproducing the duration of specific time intervals. In the current study, we examined the ability of 97 musically trained participants to reproduce the durations of temporal intervals that were filled with music or speech stimuli. The results revealed a consistent pattern of durations being underestimated, and an association was observed between the duration of musical training and the level of accuracy in reproducing both music and speech tracks.

The discrepancy of the scores on responses to negatively and positively worded items has led to hypotheses of inattention, confusion, difficulty, and differential processing of negatively worded items. The present study, utilizing eye-tracking methodology, aimed to fill an explanatory gap regarding response behavior, providing observations on the item-level response process. It experimentally examined characteristics of the items (wording type, self-relevance) and characteristics of the respondents (neuroticism, verbal abilities, and mood) for their impact on response outcomes.

Objective: To determine the contributing factors associated with major depressive disorder (MDD) in SLE patients and examine the association between disease-specific health-related quality of life [lupus quality of life (LupusQoL)] domains and MDD.

Methods: Depression was assessed by the patient health questionnaire (PHQ)-9, and scores ≥10 indicate MDD. Demographic data, LupusQoL domains, clinical and other features of the SLE patients were described and compared between MDD (PHQ-9 ≥10) and non-MDD (PHQ-9 <10) groups using χ2 tests for categorical variables and Wilcoxon rank sum tests for non-normal continuous variables.

Fluid approximations have seen great success in approximating the macro-scale behaviour of Markov systems with a large number of discrete states. However, these methods rely on the continuous-time Markov chain (CTMC) having a particular population structure which suggests a natural continuous state-space endowed with a dynamics for the approximating process. We construct here a general method based on spectral analysis of the transition matrix of the CTMC, without the need for a population structure.

The purpose of this experiment was to test how ethnic group membership of both the bullies and the victims influence the way that observers attribute human characteristics to bullies. Ethnic group membership was manipulated in terms of bullies' and victims' ethnicity (ingroup-majority group versus outgroup-minority group). Furthermore, we examined the mediating role of empathic concern towards the victim and perspective taking of the bully in the relation between ethnic group membership of bullies and victims and attributions of humanness to the bullies.
