Orders in quadratic fields, II

open access: yesProceedings of the Japan Academy, Series A, Mathematical Sciences, 1993
This work continues part I with the same title [ibid., No. 3, 45-48 (1993; Zbl 0795.11056)] and also complements the work of the authors where they dealt with the real case [Reduced ideals, the divisor function, continued fractions and class numbers of real quadratic fields, to appear in Publ. Math.].

Antiferromagnetic self-ordering of a Fermi gas in a ring cavity

open access: yesNew Journal of Physics, 2019
We explore the density and spin self-ordering of driven spin-1/2 collisionless fermionic atoms coupled to the electromagnetic fields of a ring resonator.

Strong ordering of ∗-fields

open access: yesJournal of Algebra, 1986
This paper is the third in a series of three papers (so far) in which the author discusses orderings on *-fields [the others are J. Algebra 46, 207--219 (1977; Zbl 0359.12023) and Trans. Am. Math. Soc. 262, 219--243 (1980; Zbl 0482.12009)]. A field (i.e.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Complete Ordered Fields [PDF]

open access: yes, 1977
The purpose of this thesis is to study the concept of completeness in an ordered field. Several conditions which are necessary and sufficient for completeness in an ordered field are examined. In Chapter I the definitions of a field and an ordered field

Classification of Ordered Semigroups in Terms of Generalized Interval-Valued Fuzzy Interior Ideals

open access: yesJournal of Intelligent Systems, 2016
Several applied fields dealing with decision-making process may not be successfully modeled by ordinary fuzzy sets. In such a situation, the interval-valued fuzzy set theory is more applicable than the fuzzy set theory.

Coulombic antiferromagnet in spin-1/2 pyrochlores with dipole-octupole doublets

open access: yesPhysical Review Research, 2023
An exotic state of matter could coexist with conventional orders such that the gauge fields and fractionalized excitations could prevail in a seemingly ordered state.

Computable Fields and Arithmetically Definable Ordered Fields [PDF]

open access: yesProceedings of the American Mathematical Society, 1970
Introduction. A computable field is one whose elements may be placed in one-one correspondence with the natural numbers in such a way that the number theoretic functions corresponding to the field operations are recursive. In the same vein a field is called arithmetically definable (AD for short) if its elements may be placed in one-one correspondence ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Quantum walks on graphs of the ordered Hamming scheme and spin networks

open access: yesSciPost Physics, 2019
It is shown that the hopping of a single excitation on certain triangular spin lattices with non-uniform couplings and local magnetic fields can be described as the projections of quantum walks on graphs of the ordered Hamming scheme of depth 2.
