The module orthogonal to the specht module
Journal of Algebra, 1977 We adopt the notation of [3], so that when h = (A,, A, ,..., Ak) is a proper partition of n, MA is the permutation module of the symmetric group 6, on the subgroup GA1 x GA2 x 1.. x GA1 over some field F. The Specht module, 9, is a submodule of MA. Over a field of characteristic zero, the ordinary irreducible representations of 6, are given by the ...

, 2004 We propose axioms for Kleene modules (KM). These structures have a Kleene algebra K and a Boolean algebra B as sorts. The scalar products are mappings K x B -> B; they arise as algebraic abstractions of relational image and preimage operations. KM is the basis of algebraic variants of dynamic logics.

Nonlinear-stability analysis of higher order ∆ –Σ modulators for DC and sinusoidal inputs [PDF]
, 2008 The maximum stable input limits for third-, fourth-and fifth-order Chebyshev Type II based Δ-Σ modulators are established using the Describing Function Method for DC and sinusoidal inputs.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Old drugs are new again (drugs) [PDF]
Serbian Journal of Anesthesia and Intensive Therapy, 2017 The societal cost of development of new medications is high. The faster and more economical approach is to use already proven pharmacological characteristics of drugs in use for development of new drug formulations.

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Allosteric modulators targeting GPCRs
, 2020 The remarkable precision of the pharmacological modulation, including high degree of specificity, probe dependence, and signaling bias, confers to GPCR allosteric modulators unique advantages over orthosteric classical ligands.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
