A hyperbolic problem [PDF]

open access: yesPacific Journal of Mathematics, 1985
We consider the following problem: let x belong to \(R^ n\), and t to \(R^+\), and let \(\sigma\) : \(R^ n\to R^+\) be a given Lipschitz continuous surface, with Lipschitz constant 1: (1) \(| V\sigma (x)| \leq 1\), a.e. on \(R^ n\). Let f be given in \(H^ 1_{Loc}(R^ n)\) and g in \(L^ 2_{Loc}(R^ n)\); then, we prove that there exists a solution of the ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

The visual core of a hyperbolic 3-manifold [PDF]

open access: yes, 2001
In this note we introduce the notion of the visual core of a hyperbolic 3-manifold N, and explore some of its basic properties. We investigate circumstances under which the visual core V(N') of a cover N' of N embeds in N, via the usual covering map.

Quantum Deformations and Superintegrable Motions on Spaces with Variable Curvature

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
An infinite family of quasi-maximally superintegrable Hamiltonians with a common set of (2N-3) integrals of the motion is introduced. The integrability properties of all these Hamiltonians are shown to be a consequence of a hidden non-standard quantum sl(

SCROLLS AND HYPERBOLICITY [PDF]

open access: yesInternational Journal of Mathematics, 2013
Using degeneration to scrolls, we give an easy proof of non-existence of curves of low genera on general surfaces in ℙ3of degree d ≥ 5. We also show that there exist Kobayashi hyperbolic surfaces in ℙ3of degree d = 7 (a result so far unknown), and give a new construction of such surfaces of degree d = 6.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Vector fields satisfying the barycenter property

open access: yesOpen Mathematics, 2018
We show that if a vector field X has the C1 robustly barycenter property then it does not have singularities and it is Axiom A without cycles. Moreover, if a generic C1-vector field has the barycenter property then it does not have singularities and it ...

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

open access: yesFEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Location‐Specific Hematoma Volume Predicts Early Neurological Deterioration in Supratentorial ICH

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Early neurological deterioration (END) adversely affects outcomes in patients with intracerebral hemorrhage (ICH). This study aimed to determine the location‐specific hematoma volumes for END in supratentorial ICH patients. Methods We retrospectively analyzed supratentorial ICH patients presenting from two prospective cohorts.
