Bioengineering facets of the tumor microenvironment in 3D tumor models: insights into cellular, biophysical and biochemical interactions

open access: yesFEBS Open Bio, EarlyView.
The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.

CR geometry and Cartan geometry

open access: yesForum Mathematicum, 1995
The present paper starts with the definition and study of the pre-Cartan structure modeled after a homogeneous space \(G/H\). Then the general procedure of constructing frame principal bundles and consistent Cartan connections starting from a pre-Cartan structure is described.

Slab2, a comprehensive subduction zone geometry model

open access: yesScience, 2018
Detailing subduction zones Subduction zones are responsible for the most-damaging and tsunami-generating great earthquakes. Hayes et al. updated their Slab1.0 model to include all seismically active subduction zones, including geometrically complex ...

Cognitive Resilience in Apolipoprotein ε4 Carrier Women Predicted by Neuron‐Derived Extracellular Vesicles

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The Apolipoprotein (APOE) ε4 allele is the strongest genetic risk factor for late‐onset Alzheimer's disease (AD); however, many ε4 carriers remain cognitively intact into old age. Leveraging plasma neuron‐derived extracellular vesicles (NDEVs), we sought to identify biomarkers of cognitive resilience and their interplay with APOE ...

Is the Nicolai map unique?

open access: yesJournal of High Energy Physics, 2022
The Nicolai map is a field transformation that relates supersymmetric theories at finite couplings g with the free theory at g = 0. It is obtained via an ordered exponential of the coupling flow operator integrated from 0 to g.
