Homogenization in elastodynamics with force term depending on time
International Journal of Mathematics and Mathematical Sciences, 2000 We extend the study on the homogenization problem for an elastic material containing a distributed array of gas bubbles to the case when the body force depends on time.

Automated generation of heuristics for biological sequence comparison
BMC Bioinformatics, 2005 Background Exhaustive methods of sequence alignment are accurate but slow, whereas heuristic approaches run quickly, but their complexity makes them more difficult to implement.

OPTIMAL CONTROL FOR A CONTROLLED ILL-POSED WAVE EQUATION WITHOUT REQUIRING THE SLATER HYPOTHESIS
Ural Mathematical Journal, 2020 In this paper, we investigate the problem of optimal control for an ill-posed wave equation without using the extra hypothesis of Slater i.e. the set of admissible controls has a non-empty interior. Firstly, by a controllability approach, we make the ill-

On Approximation by a Nonfundamental Sequence of Translates
Journal of Mathematical Analysis and Applications, 1996 Let \(\{c_n\}\) be a sequence of distinct real numbers satisfying the separation condition \(||c_n|^p-|c_r|^p|\leq \rho|n-r|\), \(\rho>0\), for some integer \(p>0\). Let the functions \(f(t)\) and \(F(t)\) satisfy \(f(t)= O\{\exp(-\alpha t^2)\}\), \(F(t)= O\{\exp(- at^2)\}\) as \(|t|\to\infty\) and \(\exp(-bt^2)/F(t)\in L_2(\mathbb{R})\) for some ...

RNA‐related functions of BRCA2 in transcription, replication, and genome stability
FEBS Letters, EarlyView.Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

A relationship between the modified Euler method and e
International Journal of Mathematics and Mathematical Sciences, 1985 Approximating solutions to the differential equation dy/dx=f(x,y) where f(x,y)=y by a generalization of the modified Euler method yields a sequence of approximates that converge to e. Bounds on the rapidity of convergence are determined, with the fastest

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein
FEBS Letters, EarlyView.Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Pseudo Random Number Generation through Reinforcement Learning and Recurrent Neural Networks
Algorithms, 2020 A Pseudo-Random Number Generator (PRNG) is any algorithm generating a sequence of numbers approximating properties of random numbers. These numbers are widely employed in mid-level cryptography and in software applications.

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma
FEBS Letters, EarlyView.Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.
