On the reduced minimum modulus of multiplication operators [PDF]
Mathematics and Computational SciencesIn this paper, we investigate the properties of the reduced minimum modulus in the context of Banach spaces. Given a Banach space $X$, we denote the algebra of bounded operators on $X$ as $B(X)$. Our primary focus is on examining the relationship between

ISOMETRIC AND ISOMETRIC- m OPERATORS
Aksioma: Jurnal Program Studi Pendidikan Matematika, 2017 This paper presents the definition, samples, and natures of isometric and isometric- m algebra operator for some in Hilbert space. In additions, the relationship of both operators will also be examined. To investigate natures of isometric and isometric-

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA
FEBS Open Bio, EarlyView.PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

Atomic Decomposition of Weighted Lorentz Spaces and Operators
Journal of Function Spaces, 2014 We obtain an atomic decomposition of weighted Lorentz spaces for a class of weights satisfying the Δ2 condition. Consequently, we study operators such as the multiplication and composition operators and also provide Hölder’s-type and duality-Riesz type ...

Composition and multiplication operators between Orlicz function spaces
Journal of Inequalities and Applications, 2016 Composition operators and multiplication operators between two Orlicz function spaces are investigated. First, necessary and sufficient conditions for their continuity are presented in several forms.

Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus
FEBS Open Bio, EarlyView.BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...

Algorithm 898 : efficient multiplication of dense matrices over GF(2) [PDF]
, 2010 We describe an efficient implementation of a hierarchy of algorithms for multiplication of dense matrices over the field with two elements (F-2). In particular we present our implementation in the M4RI library-of Strassen-Winograd matrix multiplication ...

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level
Aging and Cancer, EarlyView.This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...
