Exponentially accurate solution tracking for nonlinear ODEs, the higher order Stokes phenomenon and double transseries resummation [PDF]

open access: yes, 2012
We demonstrate the conjunction of new exponential-asymptotic effects in the context of a second order nonlinear ordinary differential equation with a small parameter.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

A Nonlinear Wave Equation with Jumping Nonlinearity

open access: yesDiscrete and Continuous Dynamical Systems, 1998
The authors study multiplicity of solutions \(u(x,t)\) for a piecewise linear perturbation of the one-dimensional wave operator \(u_{tt}-u_{xx}\) under Dirichlet boundary condition on the interval \((-{\pi\over 2}, {\pi\over 2})\) and periodic condition on \(t\), that is \[ \begin{cases} u_{tt}-u_{xx}+g (u)=f(x,t) \text{ in }\left(-{\pi\over 2}, {\pi ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Type I interferons modulate autophagy to shape gemcitabine response in pancreatic cancer cells

open access: yesFEBS Open Bio, EarlyView.
Type I interferons differentially modulate autophagy and the response of pancreatic cancer cells to gemcitabine. IFNα2b stimulates autophagic flux and protects cells from gemcitabine‐induced cell death, contributing to chemoresistance. In contrast, IFNβ1a inhibits autophagosome formation and enhances gemcitabine‐induced cell death, resulting in ...

On a Nonlinear Bessel Equation

open access: yesPublications of the Research Institute for Mathematical Sciences, 1972
In the theory of type II superconductivity A. A. Abrikosov discovered in 1957 that the so-called Abrikosov's mixed state can be described as a special solution of Ginzburg-Landau equation the basic equation of the theory of superconductivity (C2H). Suppose that there exists a cylindrical superconductor of type II at temperature below its critical value
