Clarifying the impact of dual optical feedback on semiconductor lasers through analysis of the effective feedback phase.

Time-delayed optical feedback is known to trigger a wide variety of complex dynamical behavior in semiconductor lasers. Adding a second optical feedback loop is naturally expected to further increase the complexity of the system and its dynamics, but due to interference between the two feedback arms, it was also quickly identified as a way to improve the laser stability. While these two aspects have already been investigated, the influence of the feedback phases, i.

Balancing disturbance risk and ecosystem service provisioning in Swiss mountain forests: an increasing challenge under climate change.

Unlabelled: Climate change severely affects mountain forests and their ecosystem services, e.g., by altering disturbance regimes.

Physical and Quality of Life Changes in Elderly Patients after Laparoscopic Surgery for Colorectal Cancer-A Prospective Cohort Study.

Background-The incidence of colorectal cancer is increasing among elderly people, where postoperative complications are frequent. Methods-We evaluated postoperative physical and quality of life changes in elderly patients undergoing laparoscopic surgery for colorectal cancer. A prospective cohort study was performed in 31 colorectal cancer patients ≥60 years who were scheduled for laparoscopic surgery due to colorectal cancer.

Handgrip strength in older adults with chronic diseases from 27 European countries and Israel.

Background/objectives: Understanding the association of deconditioned strength with the most prevalent chronic diseases in older adults and inferring possible interventional strategies is of utmost importance. We aimed to investigate the association between handgrip strength and chronic diseases in a large representative European population of adults over the age of 50 years.

Subjects/methods: Individuals aged 50 or older residing in 27 European countries and Israel participated in this cross-sectional study.
