In this paper, we present an in-house flexible and portable lidar system integrating an inexpensive, passively Q-switched laser Nd: YAG and a detection module operating in both analog and photon counting mode. This system is designed to study the atmospheric boundary layer (BL) and cirrus clouds (CC). The passively Q-switched Nd:YAG pulsed laser, operating at a second-harmonic generation (SHG) wavelength of 532 nm, features a pulse energy up to 200 mJ, a repetition rate of 1 Hz to 15 Hz, and a pulse duration of 15 ns.

In the present study, a novel indicator extracted from FRFs of beam structures is developed for crack identification. The damage indicator originated from the well-known mode assurance criterion (MAC) and therefore it is termed spectral assurance criterion (SAC).

This article presents an improved procedure for detecting single damage in beam-like structures. Many damage detection methods are based on the analysis of beam natural frequency shifts in damaged and intact states and its analytical modal curvatures. They identify the damage by constructing curves of damage coefficients along the beam and visually determining the point of their mutual intersection.

The aim of the research was the processing of the vibration signatures from healthy and damaged composite beams acquired with the help of a Scanning Laser Vibrometer (SLV) upon excitation and analysis of the mode shapes acquired for damage detection. The displacement mode shapes acquired were then converted into curvature mode shapes with the help of a Central Difference Approximation method (CDA).

The cantilever quality factor has values in the range of 190 to 505, depending on the length and resonant mode. The mass-sensitivity increases when the cantilever length decreases and reaches the highest value of 37.6 Hz/pg for the 100-µm-long cantilever. Highmode vibration was successfully exhibited for the higher mass-detection sensitivity.

A novel “turn off-on” sensor for detection of interaction between DNA and acrylamide (ACR) was developed. In this method, L-cysteine capped Mn-doped ZnS quantum dots (QDs) were used as room temperature phosphorescent probes. In the “turn-off” mode, ACR was absorbed onto the surface of QDs via electrostatic interaction, which caused a quenching effect of room-temperature phosphorescence signal by photoinduced electron-transfer mechanism. ACR was removed from the QDs’ surface with the addition of DNA.

Genome scans based on outlier analyses have revolutionized detection of genes involved in adaptive processes, but reports of some forms of selection, such as balancing selection, are still limited. It is unclear whether high throughput genotyping approaches for identification of single nucleotide polymorphisms have sufficient power to detect modes of selection expected to result in reduced genetic differentiation among populations.

The problem of using the modal curvature for crack detection is discussed in this paper based on an exact expression of mode shape and its curvature. Using the obtained herein exact expression for the mode shape and its curvature, it is demonstrated that the mode shape curvature is really more sensitive to crack than mode shape itself. Nevertheless, crack-induced change in the approximate curvature calculated from the exact mode shape by the central finite difference technique (Laplacian) is much greater in comparison with both the mode shape and curvature.

The liquid chromatography tandem mass spectrometry with electrospray ionization (ESI) source in multiple reactions monitoring (MRM) mode has been used to detect five allergen including milk, egg, peanut, soyabean, and walnut in milk, dairy products, and confectionery. The allergenic proteins from food matrices were extracted with an extraction buffer (50 mM of TRIS- saline, 2 M of urea, and 25 mM of DTT) and then enzymatically digested with trypsin to form peptides. The peptides were eventually detected on a LC-MS/MS Triple Quad 5500 system from AB SCIEX.

This paper studies the higher-order nonclassical and entanglement properties in the photonadded trio coherent state (PATCS). We use the criterion of higher-order single-mode antibunching to evaluate the role of the photon addition operation. Furthermore, the general criteria for detection of higher-order three-mode sum squeezing and entanglement features in the PATCS are also investigated.
