We propose a hybrid classical-quantum digitized-counterdiabatic algorithm to tackle the protein folding problem on tetrahedral lattice. Digitized-counterdiabatic quantum computing is paradigm developed compress algorithms via digitization of counterdiabatic acceleration given adiabatic computation. Finding lowest energy configuration amino acid sequence an NP-hard optimization that plays promin...

We investigated the appropriateness of four different mammography phantoms for image quality evaluation in Digital Breast Tomosynthesis (DBT). We tested the CIRS BR3D phantom, the ACR Prototype FFDM Accreditation Phantom, the Penn anthropomorphic breast phantom and the Quart mam/digi EPQC phantom. This work discusses the advantages and shortcomings of each phantom and concludes that none of the...

OBJECTIVE To compare between the American College of Radiology (ACR) accreditation phantom and digital mammography accreditation phantom in assessing the image quality in full-field digital mammography (FFDM). MATERIALS AND METHODS In each week throughout the 42-week study, we obtained phantom images using both the ACR accreditation phantom and the digital mammography accreditation phantom, a...
