Neutron Small Angle Scattering of Hemoglobin [PDF]

Journal of Biological Chemistry, 1972
Abstract Neutron small angle scattering experiments were performed on human hemoglobin in various mixtures of H2O and D2O. It was possible to observe the interparticle effect without corrections for resolution and to verify the first minimum and the secondary maximum in accordance with the theoretical scattering curve.

Hard Scattering and Gauge/String Duality [PDF]

, 2001
We consider high-energy fixed-angle scattering of glueballs in confining gauge theories that have supergravity duals. Although the effective description is in terms of the scattering of strings, we find that the amplitudes are hard (power law). This is a

Geant4 simulations of soft proton scattering in X-ray optics. A tentative validation using laboratory measurements [PDF]

, 2017
Low energy protons (< 300 keV) can enter the field of view of X-ray space telescopes, scatter at small incident angles, and deposit energy on the detector, causing intense background flares at the focal plane or in the most extreme cases, damaging the X ...

Small-angle Bhabha scattering [PDF]

Nuclear Physics B, 1991
Abstract Higher-order corrections to small-angle Bhabha scattering are investigated. The use of this process as a high-precision luminosity measurement at LEP requires a careful discussion of corrections beyond the well-established order-α case. It is shown that an accuracy of 0.5% necessitates the consideration of leading log order-α2 corrections ...

Diffusion‐based size determination of solute particles: a method adapted for postsynaptic proteins

FEBS Open Bio, EarlyView.
We present a diffusion‐based approach for measuring the size of macromolecules and their complexes, and demonstrate its use on postsynaptic proteins. The method requires fluorescein‐labelled protein samples, a microfluidic device that maintains laminar flow for said samples, a microscope recording the emitted fluorescent signals, and an analytic ...

Multiangle static and dynamic light scattering in the intermediate scattering angle range

, 2012
We describe a light scattering apparatus based on a novel optical scheme covering the scattering angle range $0.5\dg \le \theta \le 25\dg$, an intermediate regime at the frontier between wide angle and small angle setups that is difficult to access by ...

The Diverse Neuromuscular Spectrum of VPS13A Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective VPS13A disease (chorea‐acanthocytosis) is a rare neurodegenerative disorder caused by biallelic variants in VPS13A, typically presenting with hyperkinetic movement disorders, while neuromuscular signs are often mild. The aim of the project was to investigate the frequency and severity of neuromuscular impairment in VPS13A disease ...

Small-angle scattering and quasiclassical approximation beyond leading order

Physics Letters B, 2015
In the present paper we examine the accuracy of the quasiclassical approach on the example of small-angle electron elastic scattering. Using the quasiclassical approach, we derive the differential cross section and the Sherman function for arbitrary ...
