Compact architecture for power scaling bounce geometry lasers.

Published: February 2009

We demonstrate the compact high-power scaling of bounce geometry lasers with a new dual-pumped folded amplifier design. A Q-switched laser oscillator built with this amplifier is shown to produce over 30 W of average power from 80 W of pump power at up to 600 kHz repetition rate. In a master-oscillator power-amplifier (MOPA) configuration using the dual-pumped amplifier, we demonstrate over 100 W of output power from 250 W of pump power. We also demonstrate very high repetition rate Q-switching (1.7 MHz) of the master oscillator.

Introduction: Treatment resistant depression (TRD) affects approximately 10-30% of patients with major depressive disorder, and most patients with TRD do not respond to real-world treatments (RWT). Treatment with esketamine nasal spray (NS) plus a selective serotonin or serotonin norepinephrine reuptake inhibitor (SSRI/SNRI) has significant long-term clinical benefit over RWT in patients with TRD. However, the impact on patient-reported function remains to be determined.

Coalescence and Rebound Dynamics in Two Droplets Train Impacting on a Heterogeneous Wettability Surface.

Key Laboratory of Unsteady Aerodynamics and Flow Control, Ministry of Industry and Information Technology, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China.

Droplets that can be steered and rebound off surfaces are fundamentally interesting and important due to their promising potential in numerous applications, such as anti-icing and -fogging, spray coating, and self-cleaning. Heterogeneous wettability surfaces have been shown to be an effective means of droplet manipulation. This paper combines numerical simulation with theoretical analysis to investigate the dynamics of two droplets training impacting on and bouncing off a heterogeneous surface (superhydrophobic substrate decorated with a hydrophilic strip).

Trauma, resilience and significant relationships: Sex differences in protective factors for military mental health.

Aust N Z J Psychiatry

January 2025

Phoenix Australia Centre for Posttraumatic Mental Health, Department of Psychiatry, The University of Melbourne, Carlton, VIC, Australia.

Article Synopsis
  • Military service is largely male-dominated, leading to research predominantly focusing on male soldiers, but findings suggest that female military members experience similar or higher rates of mental health issues like PTSD.
  • A longitudinal study of nearly 8,500 Australian Defence Force members tracked changes in mental health symptoms over five years, measuring factors like trauma exposure, resilience, and relationship satisfaction.
  • The study found that while lifetime trauma exposure was a key predictor of mental health disorders for both sexes, self-reported resilience served as a significant protective factor for females, whereas being in a significant relationship helped protect males from subthreshold mental disorders.
