Analytical sensitivity factors from distributions of time of flight of photons for near-infrared spectroscopy studies in multilayered turbid media.
J Biomed Opt
January 2025
CIFICEN (UNCPBA - CICPBA - CONICET), Tandil, Argentina.
Significance: In the last years, time-resolved near-infrared spectroscopy (TD-NIRS) has gained increasing interest as a tool for studying tissue spectroscopy with commercial devices. Although it provides much more information than its continuous wave counterpart, accurate models interpreting the measured raw data in real time are still lacking.
Aim: We introduce an analytical model that can be integrated and used in TD-NIRS data processing software and toolkits in real time.

Background: Central venous catheters (CVCs) are used in pediatric patients to deliver IV fluids, blood products, medications, and nutrients. Potential complications include central line infection, which carries a high risk of morbidity and mortality in this population. Pediatric critical care nurses play a crucial role in helping to reduce the risk of infection.

The brain's activity fluctuations have different temporal scales across the brain regions, with associative regions displaying slower timescales than sensory areas. This so-called hierarchy of timescales has been shown to correlate with both structural brain connectivity and intrinsic regional properties. Here, using publicly available human resting-state fMRI and dMRI data it was found that, while more structurally connected brain regions presented activity fluctuations with longer timescales, their activity fluctuations presented lower variance.

Section of Otolaryngology Head and Neck Surgery, Department of Surgery, University of Chicago, Pritzker School of Medicine, IL. Electronic address:
Background: Black, Indigenous, People of Color (BIPOC) in medicine and women faculty have lower 10-year promotion rates than their White and male peers, despite controlling for productivity metrics. Promotion standards vary across institutions, but there is likely a common need to improve transparency and consistency while mitigating bias, inequity, and the harm of additional equity work that is commonly expected of Black, Indigenous, People of Color and women faculty (the so-called minority tax).
Methods: A promotion advisory committee consisting of clinical and research faculty at all ranks specified expectations for a faculty member at the associate or full professor ranks, with 10-15 examples given for each "mission" (clinical, research, and education).
Interactions between Per- and Polyfluoroalkyl Substances (PFAS) at the Water-Air Interface.
Environ Sci Technol
January 2025
Department of Civil and Environmental Engineering, Princeton University, Princeton, New Jersey 08544, United States.
Per- and polyfluoroalkyl substances (PFAS)─so-called "forever chemicals"─contaminate the drinking water of about 100 million people in the U.S. alone and are inefficiently removed by standard treatment techniques.
