A bstract The ultra-slow-roll (USR) inflation represents a class of single-field models with sharp deceleration the rolling dynamics on small scales, leading to significantly enhanced power spectrum curvature perturbations and primordial black hole (PBH) formation. Such transition inflationary background can trigger coherent motion scalar condensates effective potentials governed by rate inflat...

cage roll forming is one of the new methods of cold roll forming process which is widely used for producing erw pipes. in addition to less production cost and time, using cage roll forming provides smooth deformation on the strip. few studies can be found about cage roll forming because of its complexity, and the available knowledge is more experience-based and not science-based. in this paper,...

background: breast conservation therapy (bct) is the standard of care for early stage breast cancer. the procedure can be a challenge for the surgeon if the lesion is non-palpable. for excision of non-palpable breast lesions, they should be localized precisely before surgery. there are different techniques such as the wgl (wire guided localization), roll (radio-guided occult lesion localization...
