Algebraic K-theory over the infinite dihedral group: a controlled topology approach

open access: yes, 2011
We use controlled topology applied to the action of the infinite dihedral group on a partially compactified plane and deduce two consequences for algebraic K-theory.

Weak sequenceability in cyclic groups

open access: yesJournal of Combinatorial Designs, 2022
AbstractA subset of an abelian group is sequenceable if there is an ordering of its elements such that the partial sums , given by and for , are distinct, with the possible exception that we may have . In the literature there are several conjectures and questions concerning the sequenceability of subsets of abelian groups, which have been combined

A pairing between super Lie-Rinehart and periodic cyclic homology

open access: yes, 2005
We consider a pairing producing various cyclic Hochschild cocycles, which led Alain Connes to cyclic cohomology. We are interested in geometrical meaning and homological properties of this pairing.

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Digital signature scheme set in a hidden cyclic group [PDF]

open access: yesComputer Science Journal of Moldova, 2020
A new form of the hidden discrete logarithm problem is proposed as cryptographic primitive for the development of the post-quantum signature schemes, which is characterized in performing two masking operations over each of two elements from a hidden ...

Cyclic Degradation Parameters of Flow-Controlled Geomaterial for Pile Group Subjected to Torsional Loads

open access: yesApplied Sciences, 2023
The pile groups support large foundation structures which often experience cyclic torsional loads. Several theoretical and experimental investigations were carried out on pile groups under axial and lateral cyclic loads; however, the study of the ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Crosscap of the non-cyclic graph of groups

open access: yesAKCE International Journal of Graphs and Combinatorics, 2016
The non-cyclic graph CG to a non locally cyclic group G is as follows: take G∖Cyc(G) as vertex set, where Cyc(G)={x∈G|〈x,y〉  is cyclic for all  y∈G} is called the cyclicizer of G, and join two vertices if they do not generate a cyclic subgroup.
