Continuous-wave mode-locking at multi-GHz repetition rates is achieved in an ultrashort laser cavity at critical pulse energies 100 times lower than predicted by conventional theory. The authors reveal that dynamic gain depletion and recovery between consecutive round-trips is the key factor behind a low-pulse-energy transition from Q-switched mode-locking (QSML) to continuous-wave mode-locking (CWML). As well as providing new insight into gain dynamics, the results suggest a practical route to low-threshold lasing at very high-repetition rates.

Article Synopsis
  • - Wound infections complicate recovery by causing tissue damage and delays in healing; traditional microbiological diagnostics are not ideal for emergency settings due to equipment size and long turnaround times.
  • - This study developed a clinical metagenomics (CMg) workflow for analyzing wound swab samples, which was faster (about 4 hours) and provided extra info like fungal identification and antimicrobial resistance alongside standard testing.
  • - Results showed CMg achieved decent sensitivity (83.82%) and specificity (66.64%) compared to traditional methods, indicating its potential as a rapid diagnostic tool in challenging medical situations, with future improvements needed for automation and data interpretation.

Aims: The ideal dosing weight metric for enoxaparin remains elusive. Dosing remains focused on actual body weight, which may inadvertently increase the risk of bleeding in those with obesity, or ideal weight, which may underdose those with obesity. Our aim was to determine the optimal obesity-adjusted enoxaparin dosing weight.

Objectives: Persistent and significant swallowing impairment can occur in individuals with dementia. Determining prognosis and establishing realistic goals of care in this population is complex and comfort feeding may be recommended. This study aimed to establish evidence relating to patient outcomes following recommendation of comfort feeding to aid informed decision making.

One in five college students (21%) report using cannabis in the past month, and approximately 10% develop cannabis use disorder (CUD). Further, college students have high rates of trauma exposure, and CUD is prospectively linked to posttraumatic stress disorder (PTSD). Given the high rate of co-occurrence, research is needed to understand transdiagnostic, modifiable factors that could account for the relationship between CUD and PTSD.
