We report a vertically-aligned liquid crystal display (LCD) device with submillisecond response time, high transmittance, and low operation voltage. The top substrate has a common electrode, while the bottom substrate consists of hole-patterned fringing-field-switching (FFS) pixel electrodes. A negative dielectric anisotropy LC is employed. In the voltage-on state, the LC directors are reorient...

The ГК-1 self-discharging well is located in the southeastern part of Kamchatka Peninsula. a network continuous observations groundwater regime, conducted order to identify and study hydrogeochemical precursors strong earthquakes. article discusses data on changes flow rate chemical composition water for period from 1970 2022. subject analysis effects appearing under conditions non-stationary r...

Drilling a deep vertical well at low cost is very important for accelerating the exploration and development of oil gas resources. Vertical drilling BHA design key to drill well, however still an art not science in some formation. In this paper, new mechanical model bent-housing motor established, build rate prediction method considering formation properties presented uncertainties proposed. Th...

The effect of pressure on acceptor levels and hole scattering mechanisms in p-GaSe is investigated through Hall effect and resistivity measurements under quasi-hydrostatic conditions up to 4 GPa. The pressure dependence of the hole concentration is interpreted through a carrier statistics equation with a single (nitrogen) or double (tin) acceptor whose ionization energies decrease under pressur...

Micro-filters are fabricated using MEMS technology, and both measurements and numerical calculations are carried out in order to estimate the power requirement in a micron-size particle collection process using the microfilter. In order to numerically predict the pressure drop through the micro-filter, we focus on the characterization of the geometrical factors, such as internal profile of the ...
