On the nature of sub-THz continuum absorption in CO gas, its mixture with Ar, and in pure water vapor.

Detailed analysis of the unique broadband millimeter-wave (70-360 GHz) collision-induced absorption spectra in pure CO and in its mixture with Ar is presented. The nature of the observed continuum absorption is examined using classical trajectory simulation along with statistical physics consideration. Bimolecular continuum is decomposed in the phase space into separate contributions from the so-called free, quasibound, and true bound molecular pairs, the proportions of which greatly vary with temperature.

The current state of fellowship leadership in dermatology: trends in workforce demographics and scholarly productivity.

Interest in subspecialty training remains high for dermatology residency graduates. Fellowship program directors (FPDs) are largely responsible for fellowship organization and development. Here, we study the dermatology fellowship leadership landscape and identify notable differences in the characteristics of current dermatopathology, paediatric dermatology, and Mohs micrographic surgery and dermatologic oncology FPDs.

Pure rotational R(0) and R(1) lines of CO in Ar baths: experimental broadening, shifting and mixing parameters in a wide pressure range calculations.

The results of a rigorous study of the two first pure rotational transitions of CO perturbed by Ar are presented. The experimental part is based on the use of three different spectrometers covering together the pressure range from 0.02 up to 1500 torr.

Online dermatology curriculum experiences among US dermatology residents and faculty.

Many dermatology residency programs adapted to the COVID-19 pandemic by transitioning to online teaching methods. This may impact the quality of education and the satisfaction of residents. Dermatology faculty and residents nationwide were surveyed regarding their experiences with the novel online curricula.
