The nontriviality of the restriction map in the cohomology of groups. [PDF]

open access: yesProceedings of the American Mathematical Society, 1960
An unpublished result2 of B. Mazur states that if ir is any nontrivial finite group then there is an i> 0 such that Hi(Qr, Z) $0. It is, course, trivial that Hi(ir, A) #0 for some ir-module A. The point of Mazur's theorem is that we can even take A = Z, the ring of integers with trivial ir-action. Mazur's proof of this theorem is geometric. It involves

Alignment of a restriction map with the genetic map of bacteriophage T4 [PDF]

open access: yesJournal of Virology, 1981
A restriction map of the bacteriophage T4 genome was aligned with the T4 genetic map. Included were the cleavage sites for BamHI, BglII, KpnI, PvuI, SalI, and XbaI. The alignment utilized the fact that the T4 genetic map had been oriented previously with respect to a T2/T4 heteroduplex map.

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

open access: yesFEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

Spatio Temporal Analysis of Land Use Change for Supporting Landslide Exposure Assessment

open access: yesIndonesian Journal of Geography, 2014
Located in landslide prone areas, Cipanas and Pacet sub-districts are placed in areas where land uses are very dynamic. Land use change analysis is needed in these sub-districts for assessing its pattern and the driving factors that caused the change ...

A note on Hopf Cyclic Cohomology in Non-symmetric Monoidal Categories [PDF]

open access: yes, 2014
In our previous work, Hopf cyclic cohomology in braided monoidal categories, we extended the formalism of Hopf cyclic cohomology due to Connes and Moscovici and the more general case of Hopf cyclic cohomology with coefficients to the context of abelian ...

Some Restrictions on the Maps in Minimal Resolutions

open access: yesJournal of Algebra, 1998
Let \((A,{\mathfrak m})\) be a Noetherian local ring. The authors prove that there is an integer \(t=t(A)\geq 1\) such that for each finitely generated \(A\)-module \(M\) of infinite projective dimension the ideal generated by the entries of the map \(\varphi_i\) is not contained in \({\mathfrak m}^t\) for all \(i>1+\text{depth} A\), where \[ (F_ ...

Decoding the dual role of autophagy in cancer through transcriptional and epigenetic regulation

open access: yesFEBS Letters, EarlyView.
Transcriptional and epigenetic regulation controls autophagy, which exerts context‐dependent effects on cancer: Autophagy suppresses tumorigenesis by maintaining cellular homeostasis or promotes tumor progression by supporting survival under stress. In this “In a Nutshell” article, we explore the intricate mechanisms of the dual function of autophagy ...

Development of a Sequence-Based Reference Physical Map of Pea (Pisum sativum L.)

open access: yesFrontiers in Plant Science, 2019
Whole genome profiling (WGP) is a sequence-based physical mapping technology and uses sequence tags generated by next generation sequencing for construction of bacterial artificial chromosome (BAC) contigs of complex genomes.

A restriction isomorphism for cycles of relative dimension zero

open access: yes, 2016
We study the restriction map to the closed fiber of a regular projective scheme over an excellent henselian discrete valuation ring, for a cohomological version of the Chow group of relative zero-cycles. Our main result extends the work of Saito--Sato to

Autophagy in cancer and protein conformational disorders

open access: yesFEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.
