Model-Independent Semileptonic Form Factors Using Dispersion Relations

open access: yes, 1995
We present a method for parametrizing heavy meson semileptonic form factors using dispersion relations, and from it produce a two-parameter description of the B -> B elastic form factor. We use heavy quark symmetry to relate this function to B -> D* l nu

All-sky Radio SETI

open access: yes, 2017
Over the last decade, Aperture Arrays (AA) have successfully replaced parabolic dishes as the technology of choice at low radio frequencies - good examples are the MWA, LWA and LOFAR.

Tau Physics Prospects at the Tau-Charm Factory and at Other Machines [PDF]

open access: yes, 1993
The prospects for tau physics at future high-luminosity facilities are briefly discussed. Although important (and often complementary) contributions will be made from other machines, the unique experimental environment near threshold makes the Tau-Charm ...

Improved Measurement of the Electroweak Penguin Process B->Xsll

open access: yes, 2005
We present an improved measurement of the branching fraction for the electroweak penguin process B->Xsll, where l is an electron or a muon and Xs is a hadronic system containing an s-quark.

Search for B^0-> p p-bar, Lambda Lambda-bar and B^+ -> p Lambda-bar at Belle

open access: yes, 2007
We report on a new search for two-body baryonic decays of the B meson. Improved sensitivity compared to previous Belle results is obtained from 414 fb^-1 of data that corresponds to 449 million B B-bar pairs, which were taken on the Upsilon(4S) resonance

Argus ® II Retinal Prosthesis System: clinical trial results update (I)

open access: yes, 2013
Purpose: The Argus II is intended to provide electrical stimulation of the retina to induce visual perception in blind individuals with severe to profound Retinitis Pigmentosa. It consists of internal components (6x10 epiretinal electrode array, receiving coil, electronics case) and external components[for full text, please go to the a.m. URL]

Anthropogenic Space Weather

open access: yes, 2017
Anthropogenic effects on the space environment started in the late 19th century and reached their peak in the 1960s when high-altitude nuclear explosions were carried out by the USA and the Soviet Union.

Argus II users’ maximum visual acuity enhancement via the Acuboost™

open access: yes, 2013
Purpose: To demonstrate that magnification and image processing in retinal prosthesis with an external camera and processor can enable a visual acuity well beyond the limit set by theoretical resolution of the implanted array. Methods: To date, more than 60 patients blinded by outer retinal dystrophies[for full text, please go to the a.m. URL]

An Investigation, Using Standard Experimental Techniques, to Determine FLCs at Elevated Temperature for Aluminium Alloys [PDF]

open access: yes, 2012
An experimental procedure has been developed for the determination of FLCs at elevated temperatures. The GOM ARGUS system was employed for measuring surface strain based on pre-applied grids (pattern), and limit strains were determined according to the ...
