A robust, user-friendly, and automated method to determine quantum conductance in quasi-one-dimensional systems is presented. The scheme relies upon an initial density-functional theory calculation in a specific geometry after which the ground-state eigenfunctions are transformed to a maximally-localised Wannier function (MLWF) basis. In this basis, our novel algorithms manipulate and partition...

Abstract Coffee powder is obtained with a grinding machine. Espresso coffee prepared when hot water forced under pressure through the puck of powder, and optimal espresso flow rate 1 g s −1 . However, this can change for different extractions, forcing baristas to frequently setup grinder. Grinding grade one most important sources variation in quality espresso. This study tests an innovative met...

Based on the testable design techniques proposed in [12], [13], we first derive a testability measure named UCP (Entestability Cube-number Product) which can accurately indicate the extra logic needed in testable PLA. Using UCP as a cost function, we have developed two new algorithms. The first one is a restructuring algorithm named REST, and the other is a logic minimizer for testable PLA name...

Aims. We aim to study several key physical properties of quasar absorption-line systems that are subtly encoded in their absorption profiles and have not yet been thoroughly investigated or constrained.
