Hybrid storage architecture is one efficient method that can optimize the I/O performance, cost, and power consumption of storage systems. Thanks to the advances in semiconductor and optical storage technology, its application area is being expanded. It tries to store data to the most proper medium by considering I/O locality of the data. Data management between heterogeneous storage media is i...

We show that our recently reported microwave photonic jet technique for detection of deeply subwavelength pits in a metal substrate can be extended to optical wavelengths for purposes of high-density data storage. Three-dimensional finite-difference time-domain computational solutions of Maxwell's equations are used to optimize the photonic nanojet and pit configuration to account for the Drude...

This paper presents strengths and shortcomings of WinHex Specialist Edition (version 11.25 SR-7) in the context of the overall digital forensics process, focusing on its ability to preserve and examine data on storage media. No serious problems were found during non-exhaustive testing of the tool’s ability to create a forensic image of a disk, and to verify the integrity of an image. Generally ...

Based on analyzing and synthesizing the effects of In doping, Fe doping and oxidation state, we propose an efficient way to improve photorefractive properties of LiNbO3 crystal. According to the proposed way, a sample of In:Fe:LiNbO3 crystal is grown and achieves larger dynamic range, higher sensitivity and better signal-to-noise ratio thanFe:LiNbO3 crystal (Fe:0.03wt.%) that is generally consi...

Digital image archival requires less physical storage space, allows for rapid storage and retrieval and avoids loss in image quality over time or with image duplication compared with film storage. Because medical imaging data are critically important and, by law, must be stored in a safe, accessible manner, it is imperative not to have one computer error destroy all copies of the image data. Se...

With the widespread adoption of NAND-flash-based SSDs as a primary storage medium, heterogeneity in storage installations has become a norm rather than an exception. In this paper, we argue that the compatibility-driven traditional storage stack is fundamentally flawed and incapable of supporting and exploiting heterogeneity properly. After highlighting major issues with the traditional stack, ...

Magnetization manipulation is essential for basic research and applications. A fundamental question is, how fast can the magnetization be reversed in nanoscale magnetic storage media. When subject to an ultrafast laser pulse, the speed of the magnetization dynamics depends on the nature of the energy transfer pathway. The order of the spin system can be effectively influenced through spin-flip ...

This study was conducted to evaluate how acom size (small, medium and large) and acorn storage duration (0, 5 and 17 months) influenced Quercus petraea (Mattuschka) moisture content and germination. Acorn size and storage duration did not significantly affect acorn moisture content, but they significantly affected acorn germination performance. When averaged for three acorn sizes, loss of germi...

RNA integrity is a critical factor in obtaining meaningful gene expression data. Current methodologies rely on maintaining samples in cold environments during collection, transport, processing, and storage procedures, which are also extremely time-sensitive. Several RNA storage products are commercially available to help prevent degradation during the handling and storage steps; however, sample...

Music consists of strings of sound that vary over time. Technical devices, such as tape recorders, store musical melodies by transcribing event times of temporal sequences into consecutive locations on the storage medium. Playback occurs by reading out the stored information in the same sequence. However, it is unclear how the brain stores and retrieves auditory sequences. Neurons in the anteri...
