Abstract: A method of copying at least first and second files stored in a client computing device to a host server, includes the steps of: generating at the host server a first read I/O request for data of the first file based on responses to pre-read I/O requests for the first file, received from the client computing device; transmitting a merged I/O request that includes the first read I/O request for data of the first file and pre-read I/O requests for the second file from the host server to the client computing device; generating at the host server a second read I/O request for data of the second file based on responses to the pre-read I/O requests for the second file, received from the client computing device; and transmitting the second read I/O request for data of the second file from the host server to the client computing device.

Abstract: A PSA-type liquid crystal composition includes a host liquid crystal A and a polymerizable component B, where the host liquid crystal A includes one or more liquid crystal compounds, and the polymerizable component B includes at least one compound selected from compounds of general formula I-1, general formula I-2 and general formula I-3. A liquid crystal display device includes the PSA-type liquid crystal composition above. The PSA-type liquid crystal composition has better intersolubility, cannot be crystallized at a low-temperature environment, can form a relatively stable pretilt angle after the polymerization of the polymerizable component, avoids the image sticking, and inhibits the occurrence of a display defect, such as Zara Particle, during the polymerization.

Abstract: A liquid crystal composition includes one or more compounds of general Formula I in an amount of 1%-30% by weight of the total weight of the liquid crystal composition, one or more compounds of general Formula II in an amount of 5%-35% by weight of the total weight of the liquid crystal composition, and one or more compounds of general Formula III in an amount of 1%-35% by weight of the total weight of the liquid crystal composition. The liquid crystal composition has an appropriate clearing point, an appropriate optical anisotropy, an appropriate dielectric anisotropy, as well as a higher voltage holding ratio, a higher transmittance, a good high-temperature resistant performance and a faster response speed, thus being suitable for display modes, such as VA, IPS and FFS. A photoelectric display device includes the liquid crystal composition.

Abstract: Disclosed are a liquid crystal composition and a liquid crystal display device. The liquid crystal composition comprises at least one compound of general formula I, at least one compound of general formula II, at least one compound of general formula III, and at least one compound of general formula IV. By compounding the four compounds, the composition can have advantages of a wide temperature range of nematic phase, a low viscosity and a low threshold voltage, and the liquid crystal display element can have a short response time and great power saving performance.
