FEBS 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.

A Refinement of the Ray-Singer Torsion [PDF]
, 2005 This is a short version of math.DG/0505537. For an acyclic representation of the fundamental group of a compact oriented odd-dimensional manifold, which is close enough to a unitary representation, we define a refinement of the Ray-Singer torsion ...

A Python package for fast GPU‐based proton pencil beam dose calculation
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Open‐source GPU‐based Monte Carlo (MC) proton dose calculation algorithms provide high speed and unparalleled accuracy but can be complex to integrate with new applications and remain slower than GPU‐based pencil beam (PB) methods, which sacrifice some physical accuracy for sub‐second plan calculation.

Medical Journal of Australia, 1966 Abstract A series of 56 proved cases of torsion of the testis is reviewed. The condition is rare, only 2 patients per year being admitted to a large general hospital of 800 beds. The aim of this study was to assess the fate of testes in relation to the duration of symptoms: if less than 12 hours the outlook is good, between 12 and 24 ...

Physical Review D, 2003 In this article we explain discrete torsion. Put simply, discrete torsion is the choice of orbifold group action on the B field. We derive the classification H^2(G, U(1)), we derive the twisted sector phases appearing in string loop partition functions, we derive M.

Torsion theories of simplicial groups with truncated Moore complex [PDF]
arXiv, 2022 We introduce a linearly ordered lattice $\mu(Grp)$ of torsion theories in simplicial groups. The torsion theories are defined where the torsion/torsion-free subcategories are given by the simplicial groups with bounded above/below Moore complex, respectively.

Fiber-Optic Sensors for Measurements of Torsion, Twist and Rotation: A Review
Italian National Conference on Sensors, 2017 Optical measurement of mechanical parameters is gaining significant commercial interest in different industry sectors. Torsion, twist and rotation are among the very frequently measured mechanical parameters. Recently, twist/torsion/rotation sensors have
