A bstract We show that the soft part of charge generating infinitesimal superrotations can be expressed, in harmonic gauge, terms metric components evaluated at boundaries null infinity are subleading a large radius expansion. then recast spin memory observable these boundary values.

The advantage of using lasers for through silicon via (TSV) drilling is that they allow higher flexibility during manufacturing because vacuums, lithography, and masks are not required; furthermore, lasers can be applied to metal and dielectric layers other than silicon. However, conventional nanosecond lasers have disadvantages including that they can cause heat affection around the target are...

thermoelectric process in which heat energy of spark is used to remove material from the work piece. The machining process involves controlled erosion of electrically conducting material by the initiation of rapid and repetitive electrical spark discharges between the tool and workpiece separated by the dielectric medium. The present work is aimed at characterizing the electric discharge machin...

The interaction between mean flow and finite-amplitude disturbances in. certain experimentally observed unstable, compressible laminar wakes is considered theoretically without explicitly assuming small amplification rates. Boundary-layer form of the two-dimensional mean-flow momentum, kinetic energy and thermal energy equations and the time-averaged kinetic energy equation of spatially growing...

Abstract The Parisi formula is a self-contained description of the infinite-volume limit free energy mean-field spin glass models. We showthat this quantity can be recast as solution Hamilton–Jacobi equation in Wasserstein space probability measures on positive half-line.

AIM The aim of this study was to evaluate the effect of recasting base metal alloy on the metal-ceramic bond strength. MATERIALS AND METHODS A total of 60 test samples were prepared from new and recast nickel-chromium alloy and divided into six groups. In group A0, test samples were prepared from 100% new alloy. Groups A1, A2, A3, A4, and A5 were prepared from 50% new alloy and 50% casting re...

It is recognized that topographical features of cell culture surfaces, such as ridges and grooves, can dramatically influence cell phenotype, motivating the development of substrates with precisely biomimetic topography for study of the influence on cultured cells. It has been hypothesized that biomimetic topography of the small intestine may influence expression of proteins important to drug u...
