Thinking about this 1997 Edmund White quote on Fresh Air today, talking about casual gay sex in the 1970s.
Nor did all this sex preclude intimacy. For those who never lived through that period, and most of those who did, are dead, the phrase "anonymous sex" might suggest unfeeling sex, devoid of emotion. And yet, as I can attest, to hole up in a room at the baths with a body, after having opened it up and wrung it dry, to lie, head propped on a guy's stomach just where the tan line bisects it, smoke a cigarette, and talk to him late into the night and early into the morning about your childhood, his unhappiness and love, your money worries, his plans for the future. Well, nothing is more personal, more emotional.
(This is him reading a quote from his novel The Farewell Symphony)

On-chip pulse generation at 8 μm wavelength
The mid-infrared spectral region holds growing importance for applications such as gas sensing and spectroscopy. Although compact ultrashort pulse laser sources are essential to enable these applications, their realization in this spectral range remains an open challenge. We demonstrate an integrated approach to generate pulses in the mid-infrared based on chirped Bragg gratings engineered to compensate for the group delay dispersion of quantum cascade laser frequency comb sources. SiGe graded-…

clustra: A multi-platform k-means clustering algorithm for analysis of longitudinal trajectories in large electronic health records data
Background and Objective: Variables collected over time, or longitudinally, such as biologic measurements in electronic health records data, are not simple to summarize with a single time-point, and thus can be more holistically conceptualized as trajectories over time. Cluster analysis with longitudinal data further allows for clinical representation of groups of subjects with similar trajectories and identification of unique characteristics, or phenotypes, that can be investigated as risk fac…
