Deep Thermalization in Gaussian Continuous-Variable Quantum Systems.
Phys Rev Lett
December 2024
National University of Singapore, Department of Physics, Singapore 117551.
We uncover emergent universality arising in the equilibration dynamics of multimode continuous-variable systems. Specifically, we study the ensemble of pure states supported on a small subsystem of a few modes, generated by Gaussian measurements on the remaining modes of a globally pure bosonic Gaussian state. We find that beginning from highly entangled, complex global states, such as random Gaussian states and product squeezed states coupled via a deep array of linear optical elements, the induced ensemble attains a universal form, independent of the choice of measurement basis: it is composed of unsqueezed coherent states whose displacements are distributed normally and isotropically, with variance depending on only the particle-number density of the system.

Phys Rev Lett
December 2024
East China Normal University, State Key Laboratory of Precision Spectroscopy, and Hainan Institute, Shanghai, China.
We reveal a new scenario for the transition of solitons to chaos in a mode-locked fiber laser: the modulated subharmonic route. Its universality is confirmed in two different laser configurations, namely, a figure-of-eight and a ring laser. Numerical simulations of the laser models agree well with the experiments.

JAMA Netw Open
January 2025
Department of Pediatrics, The Children's Hospital at Montefiore, Albert Einstein College of Medicine, Bronx, New York.
Importance: Pediatric obesity and hypertension are highly correlated. To mitigate both conditions, provision of counseling on nutrition, lifestyle, and weight to children with high blood pressure (BP) measurements is recommended.
Objective: To examine racial and ethnic disparities in receipt of nutrition, lifestyle, and weight counseling among patients with high BP at pediatric primary care visits stratified by patients' weight status.
Background: Post-Traumatic Stress Disorder (PTSD) is a significant mental health concern in refugee populations exposed to trauma and displacement. Traditional treatments for PTSD often involve lengthy interventions. However, there's a growing interest in exploring more condensed, intensive treatments to improve outcomes and accessibility for refugees.

J Craniofac Surg
January 2025
Department of Pediatric Plastic & Reconstructive Surgery, Children's Hospital Colorado.
Introduction: Pediatric craniofacial trauma, particularly from non-accidental trauma (NAT), is a significant cause of injury with enduring physical and psychological impacts. This study analyzes demographic patterns, injury characteristics, and trends in NAT-related craniofacial injuries to inform early identification, intervention, and prevention efforts.
Methods: Analysis of the Healthcare Cost and Utilization Project Kids' Inpatient Database was performed for the years 2009 to 2019.
