AI Article Synopsis
- Monte Carlo simulations were conducted using MCNP6.2 to analyze the neutron response of a multi-element microdosimetric detector (THGEM) in various configurations (7x3, 19x5, 37x7) within a cylindrical volume of 5-cm diameter and length.
- The simulations focused on calculating the deposited energy spectrum for neutron interactions, covering an energy range from 10 keV to 2 MeV, revealing different responses between sensitive volumes and layers.
- The results showed good consistency with fluence-to-kerma conversion coefficients for energies between 10-100 keV but discrepancies occurred above 250 keV, with angular response variations being less than 10%.
Article Abstract
We present comprehensive Monte Carlo simulations for the neutron response of the multi-element microdosimetric detector based on THick Gas Electron Multiplier (THGEM). Simulations were carried out using the MCNP6.2 code to calculate the deposited energy spectrum in the gaseous sensitive volumes for three different configurations, 7 × 3, 19 × 5, 37 × 7 that occupy a cylindrical volume of 5-cm diameter by 5-cm length. The energy response was computed from 10 keV to 2 MeV. The response variation was investigated between sensitive volumes as well as between layers. The simulated energy response showed a good agreement against the evaluated fluence-to-kerma conversion coefficients in the energy region 10-100 keV, whereas discrepancies were observed in the region above 250 keV. The angular response simulations showed a variation of less than 10%.

Although deterministic analysis can provide initial insights into slope stability, there is no way to reflect the true distribution of soil properties within a slope. To further investigate the effects of the spatial variability of soil properties on the stability and failure mechanism of slope under different foundation types, this study develops a framework combining simple limit equilibrium method (LEM), Monte Carlo Simulation (MCS), and random field to incorporate these factors into slope probabilistic stability analysis. The slope models of two typical foundations (e.

However, integrating heterogeneous data types and interpreting the intricate relationships between biological features-both within and across different data views-remains a bottleneck. To address these challenges, we introduce COSIME (Cooperative Multi-view Integration and Scalable Interpretable Model Explainer).

In the field of medicine, evaluating the diagnostic performance of new diagnostic methods can be challenging, especially in the absence of a gold standard. This study proposes a methodology for assessing the performance of diagnostic tests by estimating the posterior distribution of the score using latent class analysis, without relying on a gold standard. The proposed method utilizes Markov Chain Monte Carlo sampling to estimate the posterior distribution of the score, enabling a comprehensive evaluation of diagnostic test methods.

Prenatal cell-free DNA (cfDNA) screening has advanced significantly, extending beyond detecting aneuploidies to sub-chromosomal copy number variations. However, its application for screening dominant single-gene conditions, often caused by de novo variants, remains underutilized in the general obstetric population. This study reviews recent data and experience on prenatal cfDNA screening for dominant monogenic conditions using multiple-gene panels, highlighting its potential to enhance early detection and management of genetic disorders.

Mammalian hibernation offers a unique model for exploring neuroprotective mechanisms relevant to neurodegenerative diseases. In this study, we employed untargeted lipidomics with iterative tandem mass spectrometry (MS/MS) to profile the brain lipidome of Syrian hamsters across different hibernation stages: late torpor, arousal, and euthermia (control). Previously, a lipid species identified as methyl-PA(16:0/0:0) showed a significant increase during torpor, but its precise structure was unresolved due to technological constraints.
