Comparison of three high resolution real-time spectrometers for microwave ozone profiling instruments [PDF]

, 2020
We present a comparison of digital real-time spectrometers used in ground-based radiometry for the profiling of trace gases in the middle-atmosphere. From January to June 2019, we performed parallel observations of the atmospheric ozone transition line ...

The performance of consumer-grade near infrared spectrometer in traditional Chinese medicine

Journal of the European Optical Society-Rapid Publications, 2020
Technical advances in instrument manufacturing have promoted the miniaturization and cost reduction of portable NIR spectrometers. The price of a device is now affordable to ordinary consumers, which might promotes the application of NIRS in real ...

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

Molecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Evaluating the Capability of Low-Configuration Spectrometers to Retrieve Far-Red Solar-Induced Chlorophyll Fluorescence and Its Application for Identifying Crop Growth Stages

Journal of Remote Sensing
The ground-based continuous hyperspectral remote sensing technique presents a unique opportunity to advance terrestrial ecosystem monitoring. Accurate retrieval of solar-induced chlorophyll fluorescence (SIF) relies heavily on commercially available ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Spectrometers for RF breakdown studies for CLIC [PDF]

, 2016
A e+e- collider of several TeV energy will be needed for the precision studies of any new physics discovered atthe LHC collider at CERN.  One promising candidate is CLIC, a linear collider which is based on a two-beam acceleration scheme that efficiently

Calibration and instrumental line shape characterization of a set of portable FTIR spectrometers for detecting greenhouse gas emissions [PDF]

Atmospheric Measurement Techniques, 2015
A comprehensive calibration procedure for mobile, low-resolution, solar-absorption FTIR spectrometers, used for greenhouse gases observations, is developed. These instruments commend themselves for campaign use and deployment at remote sites.

Establishing an assay to evaluate d‐amino acid oxidase enzyme kinetics and inhibition using WST‐8 redox dye

FEBS Open Bio, EarlyView.
This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.
