On overcoming Dahlquist’s second barrier for$A$-stable linear multistep methods [PDF]

Iranian Journal of Numerical Analysis and Optimization
Dahlquist’s second barrier limits the order of $A$-stable linear multistep methods to at most two, posing significant challenges for achieving higher accuracy in the numerical solution of stiff ordinary differential equations.

Explicit Methods for Integrating Stiff Cauchy Problems

Doklady Mathematics, 2019
An explicit method for solving stiff Cauchy problems is proposed. The method relies on explicit schemes and a step size selection algorithm based on the curvature of an integral curve. Closed-form formulas are derived for finding the curvature. For Runge-Kutta schemes with up to four stages, the corresponding sets of coefficients are given.

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

Molecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

Numerical solution of systems of first order stiff oscillatory differential equations using diagonally implicit super class of block backward differentiation formula [PDF]

Computational Algorithms and Numerical Dimensions
This paper introduces the development and application of a diagonally implicit 3-point method based on a superclass of the Block Backward Differentiation Formula (3DSBBDF) for solving systems of first-order stiff Oscillatory Differential Equations (ODEs)

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Constructing of linearly implicit schemes which are LN-equivalent to implicit Runge-Kutta methods [PDF]

Компьютерные исследования и моделирование, 2012
New family of linearly implicit schemes are presented. This family allows to obtain methods which are equivalent to stiffly accurate implicit Runge-Kutta schemes (such as RadauIIA and LobattoIIIC) on nonautonomous linear problems.
