Article Abstract
The purpose of this study was to test the ability of hyperspectral imaging (HSI) combined with unsupervised anomaly detectors to automatically differentiate basal cell carcinoma (BCC) from normal skin. Hyperspectral images of the face of a female patient with a BCC of the lower lip were acquired using a visible/near-infrared HSI system and two anomaly detection algorithms (Reed-Xiaoli and Reed-Xiaoli/Uniform Target hybrid anomaly detectors) were used to detect pathological tissue from normal skin. The results revealed that the receiver operating characteristic curve of the Reed-Xiaoli/Uniform Target hybrid detector was higher than that of the Reed-Xiaoli detector in the range of false positive rates between 0 and 0.8. The area under curve values were good (0.7074 and 0.8607, respectively) with Reed-Xiaoli/Uniform Target hybrid detector performing better. In conclusion, HSI combined with either of two anomaly detectors can play a promising role in the automated screening of BCC.

The sterile neutrino interpretation of the LSND and MiniBooNE neutrino anomalies is currently being tested at three liquid argon detectors: MicroBooNE, SBND, and ICARUS. It has been argued that a degeneracy between ν_{μ}→ν_{e} and ν_{e}→ν_{e} oscillations significantly degrades their sensitivity to sterile neutrinos. Through an independent study, we show two methods to eliminate this concern.

Background And Purpose: Isolated congenital middle ear malformation contributes significantly to congenital hearing loss and growth problems. This study aims to compare 0.1 mm isotropic ultra-high-resolution computed tomography and conventional high-resolution computed tomography for assessing isolated congenital middle ear malformation, using surgical exploration as the gold standard.

Innovative and reliable structural health monitoring (SHM) is indispensable for ensuring the safety, dependability, and longevity of urban infrastructure. However, conventional methods lack full efficiency, remain labor-intensive, and are susceptible to errors, particularly in detecting subtle structural anomalies such as micro-cracks. To address this issue, this study proposes a novel deep-learning framework based on a modified Detection Transformer (DETR) architecture.

Accurate detection of anomalous radioactive sources in environmental monitoring systems is critical for both radiological protection and nuclear security. This study addresses the fundamental challenge of discriminating anomalous radiation signals from natural background fluctuations, particularly at low source to background ratios. We present a novel machine learning approach for anomaly detection in gamma-ray spectra that combines neural network modeling with bio-inspired optimization.
