Optical rotatory dispersion (ORD), circular dichroism (CD), ultraviolet absorption, the fluorescence of troponin, tropomyosin, and relaxing protein were used as probes to detect structural changes resulting from the binding of troponin with tropomyosin to form a complex called relaxing protein. In the wave length region from 250 to 190 nm, ORD and CD spectra show that all the apparent band posi...

Ordered sheaves on a small quantaloid Q have been defined in terms of Q-enriched categorical structures; they form a locally ordered category Ord(Q). It has previously been shown by the second author that the " free-cocompletion " KZ-doctrine on Ord(Q) has Mod(Q), the quantaloid of Q-modules, as category of Eilenberg-Moore algebras. In the first part of this paper we apply Q-enriched category t...

Early afterdepolarizations (EADs), which are abnormal oscillations of the membrane potential at the plateau phase of an action potential, are implicated in the development of cardiac arrhythmias like Torsade de Pointes. We carry out extensive numerical simulations of the TP06 and ORd mathematical models for human ventricular cells with EADs. We investigate the different regimes in both these mo...

To elucidate the basic structure of biological membranes, experimental evidence concerning the detailed molecular organization of the proteins of membranes is required. This evidence has been almost totally lacking or ambiguous up to the present time. The Cotton effects due to the peptide bond ultraviolet absorption bands, as studied by ORD and CD, have recently proved extremely valuable in cha...

The Agaricomycetidae is one of the most morphologically diverse clades of Basidiomycota that includes the well known Agaricales and Boletales, which are dominated by pileate-stipitate forms, and the more obscure Atheliales, which is a relatively small group of resupinate taxa. This study focused taxon sampling on resupinate forms that may be related to these groups, aimed at resolving the early...

The purpose of these notes is to explain the relationship between Batanin’s categories of pruned trees and iterated bar complexes. This article is an appendix of the article [4]. Our purpose is to explain the relationship between Batanin’s categories of pruned trees (see [1, 2]) and iterated bar complexes and to revisit some constructions [4] in this formalism. The reader can use this appendix ...
