Improving timing resolution of BGO for TOF-PET: a comparative analysis with and without deep learning.

Background: The renewed interest in BGO scintillators for TOF-PET is driven by the improved Cherenkov photon detection with new blue-sensitive SiPMs. However, the slower scintillation light from BGO causes significant time walk with leading edge discrimination (LED), which degrades the coincidence time resolution (CTR). To address this, a time walk correction (TWC) can be done by using the rise time measured with a second threshold.

Applying PVEST to identify the diverse coping and identity resources with which DACAmented and undocumented latine students navigate their journeys to and through higher education.

Undocumented and DACAmented Latine high school graduates are enrolling in college at a low rate despite being eligible for in-state tuition in 25 U.S. states.

The use of assessment centers as a means to develop transformational leadership.

Today's workplace continually requires organizations to empower employees to go beyond their job description to help maintain a competitive edge in the market. Developing transformational leadership in an organization is one means in which a company can attempt to empower and inspire their employees. However, thus far there are a limited number of tools to assist in the development of transformational leadership.

Post-testicular spermatozoa of a marine teleost can conduct cytoplasmic and mitochondrial translation.

Translational silence of spermatozoa has long been considered the norm in animals. However, studies in mammals have shown that the mitochondrial ribosomal machinery is selectively activated during capacitation in the female reproductive tract, while cytosolic ribosomes remain inactive. Here, using quantitative proteomics in a piscine model species, we show that proteins involved in mRNA processing and cytoplasmic translation are predominantly accumulated in immature spermatozoa within the extratesticular excurrent ducts, while those related to flagellar motility are enriched in ejaculated (mature) sperm.

Impact of age-related changes in buccal epithelial cells on pediatric epigenetic biomarker research.

Cheek swabs, heterogeneous samples consisting primarily of buccal epithelial cells, are widely used in pediatric DNA methylation studies and biomarker creation. However, the decrease in buccal proportion with age in adults remains unexamined in childhood. We analyzed cheek swabs from 4626 typically developing children 2-months to 20-years-old.
