A method for the direct patterning of 1-alkynes onto hydrogen-terminated silicon is presented. It combines microcontact printing with illumination through the stamp, and results in the formation of an alkenyl monolayer. The formation of heterogeneous monolayers is demonstrated by subsequent backfilling.

We apply recent variations of Conservative backfilling in an effort to improve scheduler fairness. These variations modify the compression operation while preserving the key property that jobs never move later in the profile. We assess the variations using two known measures of scheduler fairness. Each of the variations turns out to be better than Conservative according to one of the metrics.

Previously conducted studies have established that surface subsidence is typically avoided by filling coal mined-out areas with solid waste. Backfilling hydraulic supports are critically important devices in backfill mining, whose operating performance can directly affect mining efficiency. To accurately evaluate the performance, this paper proposes hybrid machine learning models for states. An...

The backfill quality of a pipeline has an important influence on operation. When loose is used, the may be damaged after short term In this study, numerical simulation analysis buried pipes was carried out under three conditions: around pipe, dense backfill, and controlled low strength materials (CLSM) backfill. effects narrow trench backfilling using CLSM force deformation pipelines were studi...

Cemented rock fill (CRF) is commonly used in cut-and-fill stoping operations underground mining. This allows for the maximum recovery of ore. Backfilling can improve stope stability workings and then ground whole mine site. However, backfilling step scenarios vary from site to paper presents investigation five different their impacts on stopes at four mining levels. A comprehensive comparison d...
