On the linearized stability of age-structured multispecies populations
Journal of Applied Mathematics, 2006 We consider a general nonlinear age-structured population model with n interacting species. We deduce the characteristic function in the form of a determinant of an n-by-n matrix.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Hyperlipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Although statins are the cornerstone of lipid‐lowering therapy, their use may be limited in some patients by adverse effects. This study evaluated the possible impact of non‐drug treatment using double‐filtration plasmapheresis (DFPP) on CD14+

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Twisted forms of the determinant
Journal of Algebra, 1984 Let f be a polynomial in n variables over the field k homogeneous of degree m. Think of f as a function on a k-vector space V of dimension n. Another homogeneous polynomial \(f_ 1\) on a k-space \(V_ 1\) is called a twisted form of f split by the extension L of k if there is an L-linear isomorphism \(V_ 1\otimes L\quad \to \quad V\otimes L ...

Dynamical correlation functions in the Ising field theory
SciPost PhysicsWe study finite temperature dynamical correlation functions of the magnetization operator in the one-dimensional Ising quantum field theory. Our approach is based on a finite temperature form factor series and on a Fredholm determinant representation of ...

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

The Role of Infant Pain Behaviour in Predicting Parent Pain Ratings
Pain Research and Management, 2014 BACKGROUND: Research investigating how observers empathize or form estimations of an individual experiencing pain suggests that both characteristics of the observer (‘top down’) and characteristics of the individual in pain (‘bottom up’) are influential.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Conjecture on Minimum Covariance Determinant (MCD) Location and Scatter [PDF]
, 2009 We review Rousseeuw and van Driessen's basic theorem of Fast MCD algorithm. Later on, we present a conjecture that if minimum covariance determinant in Fast Men is replaced by minimum vector variance (MVV), then the results are not changed.
