Pulse buildup from noise and intrinsic polarization of plasma-based x-ray lasers
, 2011 The paper presents a theoretical analysis of the pulse buildup from the spontaneous noise level and variations in the intrinsic polarization state of x-ray lasers, devices utilizing amplified spontaneous emission in a high-gain medium.

Optomechanical coupling between ultracold atoms and a membrane oscillator [PDF]
, 2014 In this thesis, I report on the realization of a hybrid optomechanical system in which ultracold atoms are coupled to a micromechanical membrane. The atoms are trapped in the intensity maxima of an optical standing wave formed by retroreflection of a ...

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis
FEBS Open Bio, EarlyView.Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

Prominent Movement Disorders in RNU2‐2‐Related Spliceosomopathy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Pediatric movement disorders often overlap with neurodevelopmental diseases, suggesting shared molecular mechanisms. Variants in small nuclear RNA (snRNA) genes encoding spliceosome components have recently been associated with neurodevelopmental disorders, termed “RNUopathies.” We analyzed genome sequencing data from 14 patients with ...
