Spinor representation of surfaces and complex stresses on membranes and interfaces

open access: yes, 2011
Variational principles are developed within the framework of a spinor representation of the surface geometry to examine the equilibrium properties of a membrane or interface. This is a far-reaching generalization of the Weierstrass-Enneper representation

Representation masses of spinor genera

open access: yesDuke Mathematical Journal, 2001
Let \(f\) be an integral quadratic form of rank \(n\). The Minkowski-Siegel mass formula provides a means of determining the representation measure (or mass) of an integer \(c\) by the genus of \(f\) by expressing this quantity as a product of local factors.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

On primitive spinor exceptional representations

open access: yesJournal of Number Theory, 1987
In earlier papers a relationship between primitive representations of certain numbers \(c\) by a spinor genus of a ternary quadratic form \(f\) and primitive representations of \(ct^2\), \((t,2D)=1\), by \(f\) was established (\(D\) is the discriminant of \(f\)). This paper gives a generalization of this result to higher dimensional settings, namely to

Association of Corticospinal Tract Asymmetry With Ambulatory Ability After Intracerebral Hemorrhage

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Ambulatory ability after intracerebral hemorrhage (ICH) is important to patients. We tested whether asymmetry between ipsi‐ and contra‐lesional corticospinal tracts (CSTs) assessed by diffusion tensor imaging (DTI) is associated with post‐ICH ambulation.

Tree-level 11D supergravity amplitudes from the pure spinor worldline

open access: yesJournal of High Energy Physics
We develop a pure spinor worldline formalism for computing tree-level scattering amplitudes in 11D supergravity. Focusing first on the 4-point amplitude, we demonstrate that our prescription is consistent with BRST symmetry and gauge invariance, and that

Glymphatic Dysfunction Reflects Post‐Concussion Symptoms: Changes Within 1 Month and After 3 Months

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Mild traumatic brain injury (mTBI) may alter glymphatic function; however, its progression and variability remain obscure. This study examined glymphatic function following mTBI within 1 month and after 3 months post‐injury to determine whether variations in glymphatic function are associated with post‐traumatic symptom severity ...

Continuous spin superparticle model

open access: yesPhysics Letters B
We construct a new model of a particle propagating in 4D, N=1 superspace that describes the dynamics of a continuous spin irreducible representation of the Poincaré supergroup.

Bilinear Spinor Representation of Space-Time [PDF]

open access: yesProgress of Theoretical Physics, 1976
In this work a method of realizing the bilinear spinor representation of space-time 1s suggested, in which the usual translation transformation can be established. The basic spinors introduced are the quantities having the spinor structure with respect to the Lorentz transformation group and the isotopic transformation group as well. In the language of

Patterns of Postictal Abnormalities in Relation to Status Epilepticus in Adults

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Abnormalities on peri‐ictal diffusion‐weighted magnetic resonance imaging (DWI‐PMAs) are well‐established for patients with status epilepticus (SE), but knowledge on patterns of DWI‐PMAs and their prognostic impact is sparse. Methods This systematic review and individual participant data meta‐analysis included observational studies ...
