Existence and general stabilization of the Timoshenko system of thermo-viscoelasticity of type III with frictional damping and delay terms

Advances in Nonlinear Analysis, 2018
In this paper, we consider the following Timoshenko system of thermo-viscoelasticity of type III with frictional damping and delay terms:

Effective collective barrier for magnetic relaxation in frozen ferrofluids

, 2003
Magnetic relaxation and frequency response were measured in frozen ferrimagnetic colloids of different concentrations. A crossover from reversible to irreversible behavior is observed for concentrated colloids.

Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes

FEBS Letters, EarlyView.
The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.

Energy decay in thermoelasticity type III with viscoelastic damping and delay term

Electronic Journal of Differential Equations, 2012
In this article, we consider a thermoelastic system of type III with a viscoelastic damping and internal delay. We use the multiplier method to prove, under suitable assumptions, general energy decay results from which the exponential and polynomial ...

Rapid high resolution T1 mapping as a marker of brain development: Normative ranges in key regions of interest. [PDF]

PLoS ONE, 2018
ObjectivesWe studied in a clinical setting the age dependent T1 relaxation time as a marker of normal late brain maturation and compared it to conventional techniques, namely the apparent diffusion coefficient (ADC).Materials and methodsForty-two healthy

NONMONOTONE CONVERGENCE AND RELAXING FUNCTIONS [PDF]

International Journal of Pure and Apllied Mathematics, 2013
In the minimization of real valued functions, Newton's algorithm is often combined with a line search method. Grippo et al (SIAM J. Numer. Anal., Vol. 23, No. 4) first suggested a nonmonotone stepsize selection rule based on the maximum of a fixed set of previous function values. In this pa- per we introduce the notion of relaxing functions and suggest

Quasiparticle relaxation in optically excited high-Q superconducting resonators

, 2008
The quasiparticle relaxation time in superconducting films has been measured as a function of temperature using the response of the complex conductivity to photon flux.

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

Molecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

Subordination model of anomalous diffusion leading to the two-power-law relaxation responses

, 2010
We derive a general pattern of the nonexponential, two-power-law relaxation from the compound subordination theory of random processes applied to anomalous diffusion.

Patient‐specific pharmacogenomics demonstrates xCT as predictive therapeutic target in colon cancer with possible implications in tumor connectivity

Molecular Oncology, EarlyView.
This study integrates transcriptomic profiling of matched tumor and healthy tissues from 32 colorectal cancer patients with functional validation in patient‐derived organoids, revealing dysregulated metabolic programs driven by overexpressed xCT (SLC7A11) and SLC3A2, identifying an oncogenic cystine/glutamate transporter signature linked to ...
