Design optimization of a 1-D array of stemless plastic scintillation detectors.

Background: A stemless plastic scintillation detector (SPSD) is composed of an organic plastic scintillator coupled to an organic photodiode. Previous research has shown that SPSDs are ideally suited to challenging dosimetry measurements such as output factors and profiles in small fields. Lacking from the current literature is a systematic effort to optimize the performance of the photodiode component of the detector.

A Case of Pneumocephalus Due to an Untreated Atrial-Esophageal Fistula Post-Left Atrial Ablation Therapy.

Air embolisms can be caused by trauma, barotrauma, or due to surgical procedures in neurosurgery, vascular surgery, and cardiac surgery. An atrial-esophageal fistula (AEF) is a life-threatening complication that can occur following left atrial ablation therapy, which is used to treat refractory atrial fibrillation (Afib). AEF, if left untreated, can lead to serious neurological complications such as pneumocephalus.

Pharmacological Activation of PDC Flux Reverses Lipid-Induced Inhibition of Insulin Action in Muscle During Recovery From Exercise.

Insulin resistance is a risk factor for type 2 diabetes, and exercise can improve insulin sensitivity. However, following exercise, high circulating fatty acid (FA) levels might counteract this. We hypothesized that such inhibition would be reduced by forcibly increasing carbohydrate oxidation through pharmacological activation of the pyruvate dehydrogenase complex (PDC).

Towards space-deployable laser stabilization systems based on vibration-insensitive cubic cavities with crystalline coatings.

We present the development of a transportable laser frequency stabilization system with application to both optical clocks and a next-generation gravity mission (NGGM) in space. This effort leverages a 5-cm long cubic cavity with crystalline coatings operating at room temperature and with a center wavelength of 1064 nm. The cavity is integrated in a custom vacuum chamber with dedicated low-noise locking electronics.
