Directional Recoil Detection [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 2021
Searches for dark matter–induced recoils have made impressive advances in the last few years. Yet the field is confronted by several outstanding problems. First, the inevitable background of solar neutrinos will soon inhibit the conclusive identification of many dark matter models.

Bearing Fault Diagnosis Based on Mel Frequency Cepstrum Coefficient and Deformable Space-Frequency Attention Network

open access: yesIEEE Access, 2023
The main bearing is the core component of gas-fired generator, and its reliability directly affects the stability of the whole system. Therefore, it is of great significance to study the fault diagnosis of the main bearing of gas-fired generator.

Direct Superbubble Detection [PDF]

open access: yesAlgorithms, 2019
Superbubbles are a class of induced subgraphs in digraphs that play an essential role in assembly algorithms for high-throughput sequencing data. They are connected with the remainder of the host digraph by a single entrance and a single exit vertex. Linear-time algorithms for the enumeration superbubbles recently have become available.

Direct optical detection [PDF]

open access: yesAnalytical and Bioanalytical Chemistry, 2015
Over the last 20 years, optical methods have been increasingly used in analytical and bioanalytical applications. These methods have been applied in two rather broad ways: for direct and for indirect detection. Whereas direct-detection approaches typically enable the detection of an analyte in a single step, indirect approaches usually require the use ...

Direct Detection of Homocysteine [PDF]

open access: yesJournal of the American Chemical Society, 2004
Homocysteine (Hcy) is a biomarker for significant disorders including Alzheimer's and cardiovascular disease. The monitoring of Hcy levels in plasma is of current concern. We describe highly selective colorimetric methods for the direct detection of Hcy. Inexpensive, commercially available materials are employed.
