Silicon Drift Detectors for the Measurement and Reconstruction of Beta Spectra.

The ASPECT-BET project, or An sdd-SPECTrometer for BETa decay studies, aims to develop a novel technique for the precise measurement of forbidden beta spectra in the 10 keV-1 MeV range. This technique employs a Silicon Drift Detector (SDD) as the main spectrometer with the option of a veto system to reject events exhibiting only partial energy deposition in the SDD. A precise understanding of the spectrometer's response to electrons is crucial for accurately reconstructing the theoretical shape of the beta spectrum.

Enamel histomorphometry, growth patterns and developmental trajectories of the first deciduous molar in an Italian early medieval skeletal series.

Understanding the growth patterns and developmental trajectories of teeth during early life stages provides valuable insights into the ontogeny of individuals, particularly in archaeological populations where such information is scarce. This study focuses on first deciduous molars, specifically investigating crown formation times and daily secretion rates, through histological analysis. A total of 34 teeth from the Early Medieval necropolises of Casalmoro and Guidizzolo (Mantua, Lombardy, northern Italy) were analysed assessing growth parameters and identifying possible differences between sites and between sexes, which are determined through proteomic analysis.

Charting new territory: the early lessons in integrating social determinant of health (SDOH) measures into practice.

Quality measures for social determinants of health (SDOH) have been introduced or proposed in more than 20 federal programs, initiatives, or guidance documents to capture performance, but understanding the scope of work needed to effectively collect and align with these new measurement requirements is still in its early stages. The National Committee for Quality Assurance (NCQA) recently developed the Social Need Screening and Intervention (SNS-E) measure and is currently building 2 new domains of interest: utility insecurity and social connection. Before these domains can be leveraged to drive population health, the feasibility of collecting and reporting on them must be assessed.
