The vacuum breakdown by 10-PW-class lasers is studied in the optimal configuration of laser beams in the form of an m-dipole wave, which maximizes the magnetic field. Using 3D PIC simulations we calculated the threshold of vacuum breakdown, which is about 10 PW. We examined in detail the dynamics of particles and identified particle trajectories which contribute the most to vacuum breakdown in such highly inhomogeneous fields. We analyzed the dynamics of the electron-positron plasma distribution on the avalanche stage. It is shown that the forming plasma structures represent concentric toroidal layers and the interplay between particle ensembles from different spatial regions favors vacuum breakdown. Based on the angular distribution of charged particles and gamma photons a way to experimentally identify the process of vacuum breakdown is proposed.

Avoidable factors associated with maternal death from postpartum haemorrhage: a national Malawian surveillance study.
BMJ Glob Health
January 2025
Women's and Children's Health, University of Liverpool, Liverpool, UK.
Background: Despite strong evidence-based strategies for prevention and management, global efforts to reduce deaths from postpartum haemorrhage (PPH) have failed, and it remains the leading cause of maternal mortality. We conducted a detailed review of all maternal deaths from 33 facilities in Malawi to identify health system weaknesses leading to deaths from PPH.
Methods: Data were collected regarding every maternal death occurring across all district and central hospitals in Malawi.

Nonthermal plasma has been extensively utilized in various biomedical fields, including surface engineering of medical implants to enhance their biocompatibility and osseointegration. To ensure robustness and cost effectiveness for commercial viability, stable and effective plasma is required, which can be achieved by reducing gas pressure in a controlled volume. Here, we explored the impact of reduced gas pressure on plasma properties, surface characteristics of plasma-treated implants, and subsequent biological outcomes.
