Background: This retrospective study aims to evaluate the impact of a content-based image retrieval (CBIR) application on diagnostic accuracy and confidence in interstitial lung disease (ILD) assessment using high-resolution computed tomography CT (HRCT).
Methods: Twenty-eight patients with verified pattern-based ILD diagnoses were split into two equal datasets (1 and 2). The images were assessed by two radiology residents (3rd and 5th year) and one expert radiologist in four sessions.
Article Synopsis
- This study examined the effectiveness and reliability of study preregistration in psychology by analyzing 300 research studies to see how closely they followed their preregistered plans.
- The findings revealed that many preregistrations lacked essential methodological details and frequently deviated from their original plans, which suggests that research biases are still possible.
- To enhance the accuracy and utility of preregistration, the authors recommend improved training for researchers, more detailed registration templates, and better transparency in reporting deviations.
Particle chirality does not matter in the large-scale features of strong turbulence.

We use three-dimensional direct numerical simulations of homogeneous isotropic turbulence in a cubic domain to investigate the dynamics of heavy, chiral, finite-size inertial particles and their effects on the flow. Using an immersed-boundary method and a complex collision model, four-way coupled simulations have been performed and the effects of particle-to-fluid density ratio, turbulence strength, and particle volume fraction have been analysed. We find that freely falling particles on the one hand add energy to the turbulent flow but, on the other hand, they also enhance the flow dissipation: depending on the combination of flow parameters, the former or the latter mechanism prevails, thus yielding enhanced or weakened turbulence.

As such, clinical risk stratification among persons with very high HDL cholesterol is challenging.
Objectives: Among persons with very high HDL cholesterol, the purpose was to determine the prevalence of coronary artery calcium (CAC) and compare the association between traditional risk factors vs CAC for all-cause mortality and ASCVD.
