Perturbations of the Distal Heme Pocket in Human Myoglobin Mutants Probed by Infrared Spectroscopy of Bound CO:Correlation with Ligand Binding Kinetics
Distal Heme Pocket Human Myoglobin Mutants Probed Infrared Spectroscopy Bound CO:Correlation Ligand Binding Kinetics
2016/5/23
The infrared spectra of CO bound to human myoglobin and myoglobin mutants at positions His-64, Val-68, Asp-60, and Lys-45 on the distal side have been measured between 100 and 300 K. Large differences...
Serum aminotransferases in nonalcoholic fatty liver disease are a signature of liver metabolic perturbations at the amino acid and Krebs cycle level
fatty liver gene expression liver injury metabolomics transaminases
2018/11/27
Background: Extensive epidemiologic studies have shown that cardiovascular disease and the metabolic syndrome (MetS) are associated with serum concentrations of liver enzymes; however, fundamental cha...
Explicit Non-malleable Codes Resistant to Permutations and Perturbations
Non-malleable Codes Explicit Construction Information Theoretic
2016/1/6
A non-malleable code protects messages against various classes of tampering. Informally, a
code is non-malleable if the message contained in a tampered codeword is either the original
message, or a ...
We review several recent results showing that small piecewise smooth perturbations of integrable systems may exhibit unstable behavior on the set of initial condition
of large measure. We also presen...

We study deterministic and stochastic perturbations of incompressible flows on a two-dimensional torus. Even in the case of purely deterministic perturbations, the long-time behavior of such ...
A second order expansion of the separatrix map for trigonometric perturbations of a priori unstable systems
second order expansion separatrix map for trigonometric perturbations priori unstable systems
2015/9/25
In this paper we study a so-called separatrix map introduced by Zaslavskii-Filonenko [ZF68] and studied by Treschev and Piftankin [Tre98, Tre02,Pif06, PT07]. We derive a second order expansion of this...

The deterministic approach of sensitivity analysis is applied on the solution vector of an Air Quality Model. In
particular, the photochemical CAMx code is augmented with derivatives utilising the au...
