Instabilities, thermal fluctuations, defects and dislocations in the crystal-R-R rotator phase transitions of -alkanes.
Soft Matter
January 2025
Department of Physics, Government College of Engineering and Textile Technology, 12 William Carey Road, Serampore, Hooghly-712201, India.
The theoretical study of instabilities, thermal fluctuations, and topological defects in the crystal-rotator-I-rotator-II (X-R-R) phase transitions of -alkanes has been conducted. First, we examine the nature of the R-R phase transition in nanoconfined alkanes. We propose that under confined conditions, the presence of quenched random orientational disorder makes the R phase unstable.

This qualitative evaluation elicited feedback from genetic counselors, referring clinicians, and patients from a single healthcare organization to understand the user-driven reasons for overall satisfaction and experience. We conducted 22 in-depth, semi-structured interviews with participants from all 3 groups between February 2022 and February 2023.

With a rising incidence in an aging population, controversy surrounds surgical versus nonoperative treatments, particularly for displaced 3- and 4-part fractures in older patients. Locking plates (LP) and proximal intramedullary nails (PHN) are primary choices for surgical intervention, but both methods entail complications.

Background And Aims: Competition with sympatric diploid progenitor(s) hinders the persistence of polyploids. The hypothesis that polyploids escape from competition through niche shifts has been widely tested; however, niche escape is unlikely to completely avoid competition. Given species growing in less favorable environments likely have weaker competitive abilities, we hypothesize that polyploid populations tend to persist in areas where their progenitors with relatively low habitat suitability.

Amyotroph Lateral Scler Frontotemporal Degener
January 2025
Department of Neurology, Tokyo Metropolitan Neurological Hospital, Tokyo, Japan.
Objective: To investigate the impact of different ventilatory support options on opioid use among patients with amyotrophic lateral sclerosis (ALS).
Methods: We retrospectively reviewed 889 consecutive patients with ALS and enrolled 399 eligible patients. All patients were followed until death or tracheostomy.
