Detecting scaling in phase transitions on the truncated Heisenberg algebra

open access: yesJournal of High Energy Physics, 2021
We construct and analyze a phase diagram of a self-interacting matrix field coupled to curvature of the non-commutative truncated Heisenberg space. The model reduces to the renormalizable Grosse-Wulkenhaar model in an infinite matrix size limit and ...

Hermitian Forms over Ordered ∗ -Fields

open access: yesJournal of Algebra, 1999
Let \((D,{}^*)\) be a skew field with an involution *. Let \(Y_D\) and \(X_D\) denote space of Baer orderings and its subspace of *-orderings on \((D,{}^*).\) The main object of interest of the paper is the subring \(WS(D,{}^*)\) of the ring \({\mathcal C}(Y_D,Z)\) of continuous functions from \(Y_D\) to the ring of integers generated by the image of ...

Field-induced 3- and 2-dimensional freezing in a quantum spin liquid

open access: yes, 2000
Field-induced commensurate transverse magnetic ordering is observed in the Haldane-gap compound \nd by means of neutron diffraction. Depending on the direction of applied field, the high-field phase is shown to be either a 3-dimensional ordered N\'{e}el ...

Spin-modulated quasi-1D antiferromagnet LiCuVO_4

open access: yes, 2007
We report on magnetic resonance studies within the magnetically ordered phase of the quasi-1D antiferromagnet LiCuVO_4. Our studies reveal a spin reorientational transition at a magnetic field H_c1 ~ 25 kOe applied within the crystallographical (ab ...

Characterizing Parental Concerns About Lasting Impacts of Treatment in Children With B‐Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background B‐acute lymphoblastic leukemia (B‐ALL) is the most common pediatric cancer, and while most children in high‐resource settings are cured, therapy carries risks for long‐term toxicities. Understanding parents’ concerns about these late effects is essential to guide anticipatory support and inform evolving therapeutic approaches ...

Pseudo-ordered fields

open access: yesIndagationes Mathematicae (Proceedings), 1974
A danger in teaching familiar material is oversimplification. In this article, we shall explore an example of this. One of the authors observed a colleague (at another institution) introduce his students to the ordering of the real numbers by stating that < is a relation on ℝ which satisfies the following axiom system:

DELP Treatment on Vision and Retinal Microcirculation in Patients With Acute Ischemic Stroke: Report of Five Cases and Literature Review

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

A comprehensive review of the characterization of real numbers

open access: yesSelecciones Matemáticas
The real number system is a fundamental tool for rigorous demonstrations of the differential and integral calculus results. Even after a century of formalization on solid foundations, discussions about the construction of this field are generally omitted

Histogram Ordering

open access: yesIEEE Access, 2021
Frequency histograms are ubiquitous, being practically used in any field of science. In this paper, we present a partial order for frequency histograms and, to our knowledge, no order of this kind has been yet defined.

Two-dimensional anisotropic Heisenberg antiferromagnet in a field

open access: yes, 2005
The classical, square lattice, uniaxially anisotropic Heisenberg antiferromagnet in a magnetic field parallel to the easy axis is studied using Monte Carlo techniques.
