A comparative evaluation of outlier detection in categorical and mixed data
Outlier detection is essential in different domains such as cybersecurity and fraud detection, to name a few. However, identifying the best way to detect outliers is often a challenge. Although most algorithms are designed for numerical data, many real-world datasets contain cate...

Familial florid cemento-osseous dysplasia in two young sisters: case report and literature review
Recently identified as a variant of cemento-osseous dysplasia, familial florid cemento-osseous dysplasia (FFCOD) differs from the sporadic florid variant in both clinical and radiographic behaviour and has an autosomal dominant inheritance pattern. The aim of this study is to des...

Context-Dependent modulation of astrocytic Ca2+ signals by mitochondria: a computational study
Abstract Mitochondria regulate intracellular Ca 2+ by uptake through the mitochondrial Ca 2+ uniporter (MCU) and release via the mitochondrial permeability transition pore (mPTP). In astrocytes, neurotransmitter stimulation evokes Ca 2+ signaling, yet the role of mitochondria in...

Binary Compression and Interscale Operators on Primorial Wheels
Description This publication investigates the single scale transition (from modulus M to qM) in wheel sieves from a discrete dynamical systems perspective [1, 3]. Rather than focusing on prime-generation algorithms, the study analyzes the exact information content preserved or di...

Healthcare occupancy data as an early warning indicator of infectious disease surges in São Paulo
Early detection of infectious disease surges is critical for effective public health response, yet traditional surveillance systems often suffer from delayed reporting. Here, we investigate whether passively collected occupancy data from healthcare facilities can act as an early...
