Projectivity and freeness over comodule algebras [PDF]
, 2006 Let H be a Hopf algebra and A an H-simple right H-comodule algebra. It is shown that under certain hypotheses every (H,A)-Hopf module is either projective or free as an A-module and A is either a quasi-Frobenius or a semisimple ring. As an application it

Simple sl_{n+1}-module structures on U(h)
, 2013 We study the category M consisting of U(sl_{n+1})-modules whose restriction to U(h) is free of rank 1, in particular we classify isomorphism classes of objects in M and determine their submodule structure. This leads to new sl_{n+1}-modules.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

A superdimension formula for gl(m|n) modules [PDF]
, 2015 We give a formula for the superdimension of a finite-dimensional simple gl(m|n)-module using the Su-Zhang character formula. As a corollary, we obtain a simple algebraic proof of a conjecture of Kac-Wakimoto for gl(m|n), namely, a simple module has ...

Endo-permutation modules as sources of simple modules [PDF]
Journal of Group Theory, 2003 Let \(P\) be a finite \(p\)-group, and \(k\) an algebraically closed field of characteristic \(p\). The author considers \(kP\)-modules of the form \(\bigotimes_{Q/R\in\mathcal S}\text{Ten}_Q^P\text{Inf}^Q_{Q/R}(M_{Q/R})\), where \(M_{Q/R}\) is an indecomposable torsion endo-trivial module with vertex \(Q/R\), and \(\mathcal S\) is a set of sections of

Molecular Oncology, EarlyView.Single circulating tumor cells (sCTCs) from high‐grade serous ovarian cancer patients were enriched, imaged, and genomically profiled using WGA and NGS at different time points during treatment. sCTCs revealed enrichment of alterations in Chromosomes 2, 7, and 12 as well as persistent or emerging oncogenic CNAs, supporting sCTC identity.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Idempotent Reflexive rings whose every simle singular right module are yj-injective [PDF]
المجلة العراقية للعلوم الاحصائية, 2011 In this paper we study rightidempotent reflexive ring whose simple singular right R-module isYJ-injective, we prove that this type of ring is right weakly regular ring, we show that if R is N duo or NCI ring and R is right idempotent reflexive ring ...

A simple and highly efficient flyback inverter control strategy for AC module application
IET Power Electronics, 2023 A simple and efficient control structure of a flyback converter is proposed in this paper considering its intrinsic dynamic characteristics. The proposed control strategy makes use of a PI controller with a low pass filter to overcome the limitations on ...

Molecular Oncology, EarlyView.This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...
