Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Minimal rank factorizations of polynomial matrices
Linear Algebra and its ApplicationsWe investigate rank revealing factorizations of $m \times n$ polynomial matrices $P(λ)$ into products of three, $P(λ) = L(λ) E(λ) R(λ)$, or two, $P(λ) = L(λ) R(λ)$, polynomial matrices. Among all possible factorizations of these types, we focus on those for which $L(λ)$ and/or $R(λ)$ is a minimal basis, since they have favorable properties from the ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Algebraic Coincidence Periods Of Self – Maps Of A Rational Exterior Space Of Rank 2
مجلة بغداد للعلوم, 2010 Let f and g be a self – maps of a rational exterior space . A natural number m is called a minimal coincidence period of maps f and g if f^m and g^m have a coincidence point which is not coincidence by any earlier iterates.

A Novel Crossing Minimization Ranking Method
Applied Artificial Intelligence, 2015 The ranking problem consists of comparing a collection of observations and deciding which one is “better.” An observation can consist of multiple attributes, multiple data types, and different orders of preference. Due to diverse practical applications, the ranking problem has been receiving attention in the domain of machine learning and statistics ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding
FEBS Letters, EarlyView.In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

LINEAR MINIMAL RANK PRESERVERS ON INFINITE TRIANGULAR MATRICES
, 2015 We study the minimal rank of an infinite upper triangular matrix over a field. We characterize all linear maps on this space that preserve the minimal rank.

The minimal entropy problem for 3-manifolds with zero simplicial volume [PDF]
, 2003 In this note, we consider the minimal entropy problem, namely the question of whether there exists a smooth metric of minimal (topological) entropy, for certain classes of closed 3 ...
