A Novel Approach toward Fuzzy Generalized Bi-Ideals in Ordered Semigroups

open access: yesThe Scientific World Journal, 2014
In several advanced fields like control engineering, computer science, fuzzy automata, finite state machine, and error correcting codes, the use of fuzzified algebraic structures especially ordered semigroups plays a central role.

Methodological integration in the study of religions

open access: yesScripta Instituti Donneriani Aboensis, 1999
"Religions" constitute a field of study and accordingly "the study of religion (or religions)" is a discipline. What is a discipline, that is, in the scientific sense?

Physical properties and cellular responses of gelatin methacryloyl bulk hydrogels and highly ordered porous hydrogels

open access: yesFrontiers in Soft Matter, 2023
Protein-based hydrogels hold a high content of water in their three-dimensional (3D) network structure and exhibit innate biological activities as well as soft tissue-like mechanical properties, resulting in being highly applicable to various tissue ...

Prediction of fully compensated ferrimagnetic spin-gapless semiconducting FeMnGa/Al/In half Heusler alloys

open access: yesIUCrJ, 2019
Materials with full spin polarization that exhibit zero net magnetization attract great scientific interest because of their potential applications in spintronics. Here, the structural, magnetic and electronic properties of a C1b-ordered FeMnGa alloy are

Orders in quadratic fields, I

open access: yesProceedings of the Japan Academy, Series A, Mathematical Sciences, 1993
In Part I [ibid. 69, 45-48 (1993; Zbl 0795.11056)], the author gave a criterion for an arbitrary order to have class group generated by ambiguous ideals and also made a conjecture related to that criterion. Afterwards, however, counterexamples to the conjecture were found [cf. Part III, ibid. 70, 176-181 (1994; Zbl 0809.11064)].

Weakly ∗-ordered ∗-fields

open access: yesJournal of Pure and Applied Algebra, 1995
Let \(D\) be a division ring with involution *, center \(F\) and \([D : F] < \infty \). Since furthermore \(D\) is required to have a weak *-ordering, only the following two cases occur: (1) \((D,*)\) is a standard quaternion-algebra or (2) \([D : F]\) is odd.

Covalent Organic Frameworks for Chemical and Biological Sensing

open access: yesMolecules, 2022
Covalent organic frameworks (COFs) are a class of crystalline porous organic polymers with polygonal porosity and highly ordered structures. The most prominent feature of the COFs is their excellent crystallinity and highly ordered modifiable one ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

‐ordered differential fields [PDF]

open access: yes, 2006
peer reviewedIn his Ph.D. thesis [7], L. van den Dries studied the model theory of fields (more precisely domains) with finitely many orderings and valuations where all open sets according to the topology defined by an order or a valuation is globally ...
