We analyze the increase in precision of parameters estimation for polarization-resolved second-harmonic generation imaging microscopy when two intensities are measured with two orthogonal analyzers. The analysis is performed for measuring anisotropy parameters and molecule orientation for samples with cylindrical symmetry in the presence of photon noise with Poisson statistics. The improvement in comparison to global intensity measurement (i.e., without analyzer) is discussed.

The ability to uniquely identify a compound requires highly precise and orthogonal measurements. Here we describe a newly developed analytical platform that integrates high resolution ion mobility and cryogenic vibrational ion spectroscopy for high-precision structural characterizations. This platform allows for the temporal separation of isomeric/isobaric ions and provides a highly sensitive description of the ion's adopted geometry in the gas phase.

Time-of-flight mass spectrometry (TOF MS) excels in rapid and high-sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results. Traditional TOF instruments face a challenge: achieving high resolution often requires a very large instrument.

Article Synopsis
- A new method is developed to assess the stability of photon beams from synchrotron radiation by using a Laue crystal for diffraction imaging, allowing for the separation of beam energy and angle.
- This technique was applied to measure the energy fluctuations of the photon beam at the Shanghai Synchrotron Radiation Facility's BL09B and BL16U beamlines.
- Results indicate that the method can quickly evaluate the stability of various light sources with high energy resolution and rapid response times.
Resonant Cell-Based 1 Photoacoustic Gas Analyzer Immune to Light Power Fluctuation and Frequency Mismatch.

To overcome the light power fluctuation and frequency mismatch in photoacoustic spectroscopy (PAS), we proposed a self-corrected 1-only resonant cell-based PAS (1-RCPAS) gas analyzer. Based on the theoretical analysis of the 1 signal, a signal processing algorithm considering laser power-current nonlinearity is proposed. The 1-only algorithm is well-tailored for the resonant systems, requiring no time-division multiplexing.

This study examines the impact of canopy density, side wind speed, nozzle tilt angle, and droplet size on droplet penetration during plant protection spraying operations. Experiments conducted in citrus orchards evaluated how side wind speed and nozzle tilt angle influence droplet penetration across various canopy densities. A Phase Doppler Analyzer (PDA) was used to assess droplet size variations under different nozzle tilt angles and side wind speeds, yielding a multiple linear regression equation (R = 0.
