Singularity theory study of overdetermination in models for L-H transitions

open access: yes, 1999
Two dynamical models that have been proposed to describe transitions between low and high confinement states (L-H transitions) in confined plasmas are analysed using singularity theory and stability theory.

On attractors, spectra and bifurcations of random dynamical systems [PDF]

open access: yes, 2015
In this thesis a number of related topics in random dynamical systems theory are studied: local attractors and attractor-repeller pairs, the exponential dichotomy spectrum and bifurcation theory.

Single‐Cell Dissection Reveals Immune Dysregulation After CD5 or CD7‐Directed Chimeric Antigen Receptor T‐Cell Therapy

open access: yesAdvanced Science, EarlyView.
Single‐cell RNA/TCR/BCR sequencing reveals that 5CAR therapy in T‐ALL induces T‐cell exhaustion, reduces EBV‐associated TCRs, lowers TCR/BCR diversity, and increases NK/DC/monocyte activation and function. In contrast, 7CAR therapy reduces multiple pathogen‐associated TCRs, enhances NK cell activation and function, decreases monocyte activation, and ...

Standing and travelling waves in cylindrical Rayleigh-Benard convection

open access: yes, 2007
The Boussinesq equations for Rayleigh-Benard convection are simulated for a cylindrical container with an aspect ratio near 1.5. The transition from an axisymmetric stationary flow to time-dependent flows is studied using nonlinear simulations, linear ...

Bifurcation of finitely deformed thick-walled electroelastic cylindrical tubes subject to a radial electric field [PDF]

open access: yes, 2018
This paper is concerned with the bifurcation analysis of a pressurized electroelastic circular cylindrical tube with closed ends and compliant electrodes on its curved boundaries.

The Bifurcation of Two Invariant Closed Curves in a Discrete Model

open access: yesDiscrete Dynamics in Nature and Society, 2018
A discrete population model integrated using the forward Euler method is investigated. The qualitative bifurcation analysis indicates that the model exhibits rich dynamical behaviors including the existence of the equilibrium state, the flip bifurcation,

Geometrically Encoded Positioning of Introns, Intergenic Segments, and Exons in the Human Genome

open access: yesAdvanced Science, EarlyView.
This study introduces a new hypothesis: exons, introns, and intergenic segments are non‐random projections of the functional layers of 3D structure of chromatin packing domains. Evidence is presented that this “geometric code” may encode volumetric structure, reconciling epigenetic patterns, correlates with oncogenic mutations, acting as a potential ...

Hamiltonian Analysis of Poincar\'e Gauge Theory: Higher Spin Modes [PDF]

open access: yes, 2001
We examine several higher spin modes of the Poincar\'e gauge theory (PGT) of gravity using the Hamiltonian analysis. The appearance of certain undesirable effects due to non-linear constraints in the Hamiltonian analysis are used as a test.
