Design of a Littrow-type diode laser with independent control of cavity length and grating rotation.

Opt Lett 2021 Jun;46(12):2840-2843

We present a novel, to the best of our knowledge, extended-cavity diode laser based on a modified Littrow configuration. The coarse wavelength adjustment via the rotation of a diffraction grating is decoupled from the fine tuning of the external cavity modes by positioning a piezo transducer behind the diode laser, making the laser robust against misalignment and hysteresis even with long external cavities. Two laser prototypes with external cavities of different lengths were tested with a 780 nm laser diode, and locked to an atomic reference. Read More

Neocortical circuits in pain and pain relief.

Nat Rev Neurosci 2021 Jun 14. Epub 2021 Jun 14.

Institute of Pharmacology, Heidelberg University, Heidelberg, Germany.

The sensory, associative and limbic neocortical structures play a critical role in shaping incoming noxious inputs to generate variable pain perceptions. Technological advances in tracing circuitry and interrogation of pathways and complex behaviours are now yielding critical knowledge of neocortical circuits, cellular contributions and causal relationships between pain perception and its abnormalities in chronic pain. Emerging insights into neocortical pain processing suggest the existence of neocortical causality and specificity for pain at the level of subdomains, circuits and cellular entities and the activity patterns they encode.

Interpreting deep learning models for epileptic seizure detection on EEG signals.

Artif Intell Med 2021 Jul 1;117:102084. Epub 2021 May 1.

Embedded Systems Laboratory (ESL), EPFL, Lausanne, Switzerland.

While Deep Learning (DL) is often considered the state-of-the art for Artificial Intel-ligence-based medical decision support, it remains sparsely implemented in clinical practice and poorly trusted by clinicians due to insufficient interpretability of neural network models. We have approached this issue in the context of online detection of epileptic seizures by developing a DL model from EEG signals, and associating certain properties of the model behavior with the expert medical knowledge. This has conditioned the preparation of the input signals, the network architecture, and the post-processing of the output in line with the domain knowledge. Read More

Which factors contribute to sexual well-being? A comparative study among 17 to 20 year old boys and girls in Belgium and Ecuador.

Cult Health Sex 2021 Jun 14:1-17. Epub 2021 Jun 14.

Department of Public Health and Primary Care, Ghent University, Ghent, Belgium.

Despite recognition that sexual well-being is an important part of adolescent sexual and reproductive health, a clear description of adolescent sexual well-being does not yet exist. Through six in-depth interviews and four focus group discussions with 56 young people in two distinct contexts (Belgium and Ecuador), we used the social-ecological framework to identify factors influencing adolescent sexual well-being. According to respondents, the main factors that influence adolescent sexual well-being are not only situated at the individual (having knowledge and skills and being physically, sexually and mental mature and healthy) and interpersonal levels (positive attraction towards others and communication about sexuality), but at a broader societal level, including social acceptance of sex, gender and sexual diversity and its (legal) translation into comprehensive sexuality education and the ready availability of contraceptives.
