Article Synopsis
  • Turbulence and magnetic reconnection are important nonlinear plasma phenomena that significantly affect energy transport in space and astrophysical plasmas.
  • Recent high-resolution, multi-spacecraft observations have improved our understanding of their complex interactions, revealing how turbulence generates current sheets that can undergo reconnection.
  • This paper reviews current knowledge on these interactions in collisionless plasmas, particularly in Earth's magnetosphere, highlighting findings from NASA's missions in key areas like the magnetosheath and magnetotail.

Background: Maximum voided volumes (MVV) and maximum bladder capacities (MBC) are important parameters in the evaluation of lower urinary tract functions in children. However, consistency of MVV and MBC measurements between voiding diary (VD), uroflowmetry (UF) and cystometrography (CMG) in children with non-neurogenic lower urinary tract dysfunction (LUTD) has not been addressed specifically.

Objective: We aimed to compare the MVV in VD and UF and MBC in CMG in children with non-neurogenic LUT dysfunction and investigate for possible factors for discrepancies.

Turbulent energy dissipation is a fundamental process in plasma physics that has not been settled. It is generally believed that the turbulent energy is dissipated at electron scales leading to electron energization in magnetized plasmas. Here, we propose a micro accelerator which could transform electrons from isotropic distribution to trapped, and then to stream (Strahl) distribution.

Article Synopsis
  • Particles in space can reach very high energy levels during explosive events, and magnetic reconnection is a key process in understanding how this happens in Earth's magnetosphere.
  • Recent spacecraft missions have improved our ability to study particle acceleration at specific structures, revealing important insights into the mechanisms at play.
  • Further research is necessary to fully comprehend particle acceleration, particularly regarding energy distribution and the role of turbulence, and to compare findings with other plasma environments like those in solar and astrophysical contexts.

Background: Lung cancer is the leading cause of cancer-related deaths worldwide. Before beginning lung cancer treatment, it is necessary to complete procedures such as suspecting lung cancer, obtaining a pathologic diagnosis, and staging. This study aimed to investigate the processes from suspicion of lung cancer to diagnosis, staging, and treatment initiation.
