Correction of Distorted Wavefront Using Dual Liquid Crystal Spatial Light Modulators

Photonics, 2022
In space optical communication, owing to the influence of atmospheric turbulence, optical beams lose focus and become phase-distorted, which reduces the communication quality.

Coherent Adaptive Optical System

Conference on Lasers and Electro-Optics, 2017
An adaptive optical system in which coherent images are processed to determine wavefront error and the error is corrected by applying the inverse to a deformable mirror is discussed.

Cognitive Functioning in Vorinostat‐Treated Pediatric and Young Adult Patients Over the First 180 Days After Hematopoietic Stem Cell Transplant

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Cognitive and psychological difficulties could negatively interfere with treatment adherence and quality of life before and after hematopoietic stem cell transplant (HSCT). Methods to mitigate these changes may have positive effects on treatment success.

Production of Phase Screens for Simulation of Atmospheric Turbulence

, 2012
The ability to simulate atmospheric turbulence in the lab is a crucial part of testing and developing astronomical adaptive optics technology. We report on the development of a technique for creating phase plates, which involves the strategic application

A Substellar Common Proper Motion Companion to the Pleiad HII 1348 [PDF]

, 2011
We announce the identification of a proper motion companion to the star HII 1348, a K5V member of the Pleiades open cluster. The existence of a faint point source 1.1arcsec away from HII 1348 was previously known from adaptive optics imaging by Bouvier ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
