Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae
FEBS Open Bio, EarlyView.Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Collaborative Spectrum Sensing Based on Distributed Adaptive Filtering
IEEE Open Journal of the Communications SocietySpectrum sharing technology can reduce the problem of limited spectrum resources failing to meet the demands of multiple users, and it is one of the important topics in effectively integrating existing communication technologies with the sixth-generation

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‐

A DASP multiband spectrum sensing method based on total random sampling on Grid without replacement [PDF]
, 2011 This paper proposes a method that deploys nonuniform sampling and spectral analysis to perform reliable spectrum sensing using sampling rates well below the ones demanded by uniform-sampling-based DSP.

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

FEBS Open Bio, EarlyView.Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

Energy-Efficiency Maximization for Cooperative Spectrum Sensing in Cognitive Sensor Networks [PDF]
, 2017 Spectrum sensing is the prerequisite of opportunistic spectrum access in cognitive sensor networks (CSNs) as its reliability determines the success of transmission. However, spectrum sensing is an energy-consuming operation that needs to be minimized for
