Photoswitching Molecules Functionalized with Optical Cycling Centers Provide a Novel Platform for Studying Chemical Transformations in Ultracold Molecules.

A novel molecular structure that bridges the fields of molecular optical cycling and molecular photoswitching is presented. It is based on a photoswitching molecule azobenzene functionalized with one and two CaO- groups, which can act as optical cycling centers (OCCs). This paper characterizes the electronic structure of the resulting model systems, focusing on three questions: (1) how the electronic states of the photoswitch are impacted by a functionalization with an OCC; (2) how the states of the OCC are impacted by the scaffold of the photoswitch; and (3) whether the OCC can serve as a spectroscopic probe of isomerization.

7 days of L-citrulline supplementation does not improve running performance in the heat whilst in a hypohydrated state.

Purpose: 7 days L-citrulline supplementation has been reported to improve blood pressure, O kinetics, gastrointestinal (GI) perfusion and endurance cycling performance through increasing arterial blood flow. In situations where blood volume is compromised (e.g.

ThF thin films for solid-state nuclear clocks.

After nearly 50 years of searching, the vacuum ultraviolet Th nuclear isomeric transition has recently been directly laser excited and measured with high spectroscopic precision. Nuclear clocks based on this transition are expected to be more robust than and may outperform current optical atomic clocks. These clocks also promise sensitive tests for new physics beyond the standard model.

[Bernadette through the ages: An evolving perspective on psychiatric care from institutionalization to alternatives to hospitalization].

In 1909, 21-year-old Bernadette was hospitalized after the parish priest deemed her to be suffering from "puerperal insanity." She was committed to Saint-Jean-de-Dieu, separated from her newborn and husband, who would send dozens of letters inquiring about her health and longing for the day she could return home. Sadly, that return never happened.
