Breast uptake on a myocardial perfusion scan

open access: yesWorld Journal of Nuclear Medicine, 2021
A 42-year-old female underwent a myocardial perfusion scan (MPS) for the evaluation of coronary artery disease. Raw and cine loop images hinted at abnormal tracer accumulation in the chest.

Automated Placement of Scan and Pre-Scan Volumes for Breast MRI Using a Convolutional Neural Network

open access: yesTomography, 2023
Graphically prescribed patient-specific imaging volumes and local pre-scan volumes are routinely placed by MRI technologists to optimize image quality. However, manual placement of these volumes by MR technologists is time-consuming, tedious, and subject

A scan of f(R) models admitting Rindler type acceleration

open access: yes, 2013
As a manifestation of large distance effect Grumiller modified Schwarzschild metric with an extraneous term reminiscent of Rindler acceleration. Such a term has the potential to explain the observed flat rotation curves in general relativity.

Selective Laser Sintering of Stainless Steel 314S HC Processed Using Room Temperature Powder Beds [PDF]

open access: yes, 1999
Metal powder bed pre-heating is a proposed route for the homogenisation of temperature gradients that can otherwise cause individual layer warping and cracking in direct metal Selective Laser Sintering (SLS).

Lepton Mixing Patterns from a Scan of Finite Discrete Groups

open access: yes, 2013
The recent discovery of a non-zero value of the mixing angle theta_13 has ruled out tri-bimaximal mixing as the correct lepton mixing pattern generated by some discrete flavor symmetry (barring large next-to-leading order corrections in concrete models).

Towards a Realistic MSSM Prediction for Neutrino-nucleon Deep-inelastic Scattering [PDF]

open access: yes, 2006
We discuss the radiative corrections to charged and neutral current deep-inelastic neutrino--nucleon scattering in the minimal supersymmetric standard model (MSSM).
