Possible role of human ribonuclease dicer in the regulation of R loops

FEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

KINETIC METHODS OF TREATMENT IN WHIPLASH – REAR-END [PDF]

Annals of the “Ştefan cel Mare” University: Physical Education and Sport Section - The Science and Art of Movement, 2018
Whiplash is a neck-head trauma, and is most commonly encountered in auto accidents or sports in which speed is one of the contributory factors. The mechanism relates to the collision between two vehicles. The important factors to be considered are the

Collisions and perception [PDF]

ACM Transactions on Graphics, 2001
Level of Detail (LOD) techniques for real-time rendering and related perceptual issues have received a lot of attention in recent years. Researchers have also begun to look at the issue of perceptually adaptive techniques for plausible physical simulations. In this article, we are particularly interested in the problem of realistic collision simulation

AAPM medical physics practice guideline 13.a: HDR brachytherapy, part B

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract The goal of this report is to assist the clinical medical physicist in assuring that key quality standards and practice considerations are met to ensure safe, reliable, and reproducible high dose rate (HDR) brachytherapy (BT) treatment. This guideline has been developed to provide appropriate minimum standards for such services.

Vortex Collisions: Crossing or Recombination?

, 2001
We investigate the collision of two vortex lines moving with viscous dynamics and driven towards each other by an applied current. Using London theory in the approach phase we observe a non-trivial vortex conformation producing anti-parallel segments ...

Comparative Wear and Friction Analysis of Sliding Surface Materials for Hydrostatic Bearing under Oil Supply Failure Conditions

Advanced Engineering Materials, EarlyView.
Hydrostatic bearings excel in high‐precision applications, but their performance hinges on a continuous external supply. This study evaluates various material combinations for sliding surfaces to mitigate damage during supply failures or misalignment and to discover the most effective materials identified for enhancing the reliability and efficiency of

Linear Waves in Partially Ionized Plasmas in Ionization Non-equilibrium

Frontiers in Astronomy and Space Sciences, 2019
We aim to investigate the properties of linear Alfvén and slow magnetoacoustic waves in a partially ionized plasma in ionization non-equilibrium. The propagation characteristics of these waves are studied within the framework of a two-fluid plasma in ...
