Cardiovascular function and ballistocardiogram: a relationship interpreted via mathematical modeling [PDF]
, 2019 Objective: to develop quantitative methods for the clinical interpretation of the ballistocardiogram (BCG). Methods: a closed-loop mathematical model of the cardiovascular system is proposed to theoretically simulate the mechanisms generating the BCG ...

Quantitative imaging methods in osteoporosis [PDF]
Quantitative Imaging in Medicine and Surgery, 2016 Osteoporosis is characterized by a decreased bone mass and quality resulting in an increased fracture risk. Quantitative imaging methods are critical in the diagnosis and follow-up of treatment effects in osteoporosis. Prior radiographic vertebral fractures and bone mineral density (BMD) as a quantitative parameter derived from dual-energy X-ray ...

A Rational Risk Policy? Why Path Dependence Matters
Entropy, 2023 The Kelly criterion determines optimal bet sizes that maximize long-term growth. While growth is definitely an important consideration, the focus on growth alone can lead to significant drawdowns, leading to psychological discomfort for a risk-taker ...

Quantitative comparison of filtering methods in lattice QCD
, 2007 We systematically compare filtering methods used to extract topological excitations (like instantons, calorons, monopoles and vortices) from lattice gauge configurations, namely APE-smearing and spectral decompositions based on lattice Dirac and Laplace ...

Population Ecology, EarlyView.Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

Single Imputation Methods and Confidence Intervals for the Gini Index
Mathematics, 2021 The problem of missing data is a common feature in any study, and a single imputation method is often applied to deal with this problem. The first contribution of this paper is to analyse the empirical performance of some traditional single imputation ...

A researcher's dilemma- philosphical and methodological pluralism [PDF]
, 2004 In many research textbooks the distinction between qualitative and quantitative research is inadvertently linked with philosophical perspectives. This in essence creates a mutually exclusive relationship between method and philosophy.

FEBS Letters, EarlyView.B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...
