Introduction The decision to admit an older patient to the intensive care unit (ICU) should reflect shared goals of care. Resource limitations during the Covid-19 pandemic highlighted challenges in selecting candidates for escalation. Patients and ne

Underlying ischaemic disease should be excluded in patients with delayed wound healing. Contrast angiography is a useful imaging method for assessing the specific cause of wound chronicity and may also be helpful in assessing the aetiology of unexpla

The authors have developed a copper vapor laser based micro machining system using advanced beam quality control and precision wavefront tilting technologies. Micro drilling has been demonstrated through percussion drilling and trepanning using this

The scaling characteristics of large diameter (6≤d≤12 cm) high repetition‐rate copper‐vapor lasers are investigated using a radially dependent laser‐discharge model. Results of the model are verified with experimental data obtained on sever

Laser action in singly ionized metal atoms has been obtained when a rare gas is excited in a metal hollow cathode. The required metal‐vapor density is produced by discharge sputtering from the cathode and the excitation of upper levels occurs via a

We report a multiline output power of 1 W from the 800.4, 825.5, and 840.4 nm Ag II transitions and 350 mW from the 408.6 nm Ag II transition resulting from pulsed operation of a silver hollow cathode laser. Continuous output of 1 W was obtained in a

We have developed a computational model for pulse amplification by a pulsed electric discharge laser amplifier. We applied the model to the copper vapor system, for which the oscillator has previously been modeled on a 0-D level1 and a 1-D level.2 Th
