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.

The 2-methyl-4-nitroaniline (NA) was converted into the raw material N-benzyl-2-methyl-4-nitroaniline (BNA), and the solubility of BNA in various organic solvents was calculated gravimetrically. BNA’s solubility and crystal structure make it an excellent solvent for the low-temperature solution growth method used to create single crystals of BNA with orthorhombic structure studied through single crystal analysis.

Ebook "Calculations on nonlinear optical properties for large systems: The elongation method" describes the quantum-mechanical treatment of the response to one or more external oscillating electric fields for molecular and macroscopic, crystalline systems. To calculate NLO properties of large systems, a linear scaling generalized elongation method for the efficient and accurate calculation is introduced.

Ebook "Non-linear optical response in atoms, molecules and clusters: An explicit time dependent density functional approach" is to present, in sufficient detail, a non-perturbative technique for calculating optical hyperpolarizabilities. The ability to efficiently compute hyperpolarizabilities, for a variety of different molecular systems, makes this brief invaluable for those engaged in the computational design of new electro-optical materials.

Gastrointestinal stromal tumor (GIST) is currently regarded as a potentially malignant tumor, and early diagnosis is the best way to improve its prognosis. Therefore, it will be meaningful to develop a new method for auxiliary diagnosis of this disease.

In this paper, the control design for the grid-connected converter used as a part of the wind turbine generator is discussed. First, the three-phase T-type multilevel converter, which exhibits several advantages such as low total harmonic distortion, reduced voltage stress, and switching loss, is employed for the power stage. Second, finite control set model predictive control (FCS-MPC) is adopted to achieve a multi-objective optimization solution for the inner grid-connected current control loop.

Metastases are the leading cause of breast cancer-related deaths. The tumor microenvironment impacts cancer progression and metastatic ability. Fibrillar collagen, a major extracellular matrix component, can be studied using the light scattering phenomenon known as second-harmonic generation (SHG).

This paper presents modified Stator Fed Oriented Control (SFOC)for Doubly Fed Induction Generator (DFIG) in wind turbines during grid unbalance,and improves stability by using Notch filter to eliminate second order harmonic components.The proposed schemes apply multiple PI controllers with Fuzzy and anti-windup (PI-F) to obtain commanded rotor currents and also introduce extra commanded values for rotor currents.

Matrix metalloproteases and collagen are key participants in breast cancer, but their precise roles in cancer etiology and progression remain unclear. MMP13 helps regulate collagen structure and has been ascribed largely harmful roles in cancer, but some studies demonstrate that MMP13 may also protect against tumor pathology.

Preoperative radiochemotherapy improves outcomes in patients with locally advanced rectal carcinoma, and has been used increasingly in patient management. However, there is a strong clinical need to assess tumor response to neoadjuvant treatment, and a non-invasive technique that allows the precise identification of morphologic changes in tumors would be of considerable clinical interest.

Ovarian cancer remains the most deadly gynecological cancer with a poor aggregate survival rate; however, the specific rates are highly dependent on the stage of the disease upon diagnosis. Current screening and imaging tools are insufficient to detect early lesions and are not capable of differentiating the subtypes of ovarian cancer that may benefit from specific treatments.

Early gastric cancer is associated with a much better prognosis than advanced disease, and strategies to improve prognosis is strictly dependent on earlier detection and accurate diagnosis. Therefore, a label-free, non-invasive imaging technique that allows the precise identification of morphologic changes in early gastric cancer would be of considerable clinical interest.

The traditional pathologic grading for human renal cell carcinoma (RCC) has low concordance between biopsy and surgical specimen. There is a need to investigate adjunctive pathology technique that does not rely on the nuclear morphology that defines the traditional grading.

Sum frequency generation (SFG) spectra of cotton cellulose fibers were successfully obtained with IR wavenumber from 2800 to 3400 cm-1 . The spectra showed the two peaks at 2840 cm-1 and 2941 cm-1 assigned to symmetric and asymmetric CH2 stretching modes, respectively. There was also a peak obtained at wavenumber 2959 cm-1 assigned to the overtone of H-O-C bending at Fermi resonance with 2941 cm-1 peak.
