Walsh, C., Gorman, D., Byrne, P., Larkin, A., Dowling, A., Malone, J. F.
Computed radiography (CR) and digital radiography (DR) are replacing traditional film screen radiography as hospitals move towards digital imaging and picture archiving and communication systems...
Gray, L., Dowling, A., Gallagher, A., Gorman, D., O'Connor, U., Devine, M., ...
This study presents the findings from acceptance testing and routine quality control (QC) of general radiographic X-ray equipment in Ireland during 2006 and early 2007, including mobile X-ray units...
QA/acceptance testing of DEXA X-ray systems used in bone mineral densitometry (2008)
Larkin, A., Sheahan, N., O'Connor, U., Gray, L., Dowling, A., Vano, E., ...
New developments in dual energy X-ray absorptiometry (DEXA) imaging technology [fan beam and cone beam (CB)] result in higher exposure levels, shorter scan times, increased patient throughput and...
Acceptance testing and QA of interventional cardiology systems (2008)
Dowling, A., Gallagher, A., O'Connor, U., Larkin, A., Gorman, D., Gray, L., ...
Interventional cardiology (IC) is a rapidly growing field of medical specialisation. Such procedures are complex and may subject patients and operators to higher levels of risk than those encountered...
Patient dose in interventional radiology: a European survey (2008)
Vano, E., Järvinen, H., Kosunen, A., Bly, R., Malone, J., Dowling, A., ...
Patient doses for a few common fluoroscopy-guided procedures in interventional radiology (IR) (excluding cardiology) were collected from a few radiological departments in 13 European countries. The...
Acceptance testing of fluoroscopy systems used for interventional purposes (2008)
O'Connor, U., Dowling, A., Gallagher, A., Gorman, D., Walsh, C., Larkin, A., ...
This study presents the results of acceptance testing on 18 interventional fluoroscopy systems in Ireland. Acceptance testing and routine quality assurance (QA) of X-ray systems are the requirements...
Writing software or writing scientific articles? (2007)
Basaglia, Tullio, Bell, Z W, Dressendorfer, P V, Larkin, A, Pia, M G
An analysis of publications related to high energy physics computing in refereed journals is presented. The distribution of papers associated to various fields of computing relevant to high energy...
Nonlinear conduction of sliding electronic crystals: Charge and Spin Density Waves (2005)
A model of local metastable states due to the pinning induces plastic deformations allows to describe the nonlinear I-V curves in sliding density waves -DW. With increasing the DW velocity v, the...
Ehrenfest time in the weak dynamical localization (2004)
Tian, C., Kamenev, A., Larkin, A.
The quantum kicked rotor (QKR) is known to exhibit dynamical localization in the space of its angular momentum. The present paper is devoted to the systematic first--principal (without a regularizer)...
Weak dynamical localization in periodically kicked cold atomic gases (2004)
Tian, C., Kamenev, A., Larkin, A.
Quantum kicked rotor was recently realized in experiments with cold atomic gases and standing optical waves. As predicted, it exhibits dynamical localization in the momentum space. Here we consider...

Strong Pinning and Plastic Deformations of the Vortex Lattice (1996)
Schönenberger, A., Larkin, A., Heeb, E., Geshkenbein, V., Blatter, G.
We investigate numerically the dynamically generated plastic deformations of a 3D vortex lattice (VL) driven through a disorder potential with isolated, strong pinning centers (point-like or extended...
Hyaluronic acid capsule: strategy for oxygen resistance in group A streptococci.
Unencapsulated variants of encapsulated, M-protein-positive group A streptococci are oxygen sensitive and secrete inhibitory concentrations of hydrogen peroxide when grown in aerated broth cultures....
