Advanced Science, EarlyView.A light‐activated catheter insert combines antimicrobial blue light with nitric oxide release to generate complementary oxidative and nitrosative stress, producing potent broad‐spectrum antimicrobial activity. The approach achieves greater than 4‐log reductions in bacterial and fungal viability and significantly reduces Staphylococcus aureus ...

Angewandte Chemie, EarlyView.Direct synthesis of sulfonimide‐based polymers of intrinsic microporosity enables comparison with compositionally similar flexible analogs. Incorporation of a common pore‐filling transport medium drives these fundamentally different polymer architectures toward similar bulk conductivity and mechanical properties while revealing distinct microscopic ion‐

Faraday polarization fluctuations and their dependence on post sunset secondary maximum and amplitude scintillations at Delhi [PDF]
Annales Geophysicae, 2002 VHF Faraday rotation (FR) and amplitude scintillation data recorded simultaneously during May 1978–December 1980 at Delhi (28.63° N, 77.22° E; Dip 42.44° N) is analyzed in order to study the Faraday polarization fluctuations (FPFs) and their ...

Advanced Science, EarlyView.GALK1 acts as a protein kinase beyond the phosphorylation of galactose. GALK1 phosphorylates TIMM13 at Y73 in the cytoplasm. This phosphorylation prevents premature oxidative folding of TIMM13 and ensures its entrance into the intermembrane space of mitochondrion, positively regulating mitochondrial respiration.

Monitoring ionospheric scintillations with GNSS in South America
, 2021 At equatorial latitudes, during specific conditions, Global Navigation Satellite System (GNSS) signals traversing the ionospheric layer might experience fluctuations in phase and/or amplitude, the so-called ionospheric scintillations.

Non‐Covalent Reversibly Photoconvertible Fluorescent Tags for Wash‐Free Protein Labeling
Advanced Science, EarlyView.FAST proteins combined with one or two fluorogens undergo reversible fluorescence switching or photoconversion through photoisomerization. At low fluorogen concentration and high light intensity, they act as negative or positive photoswitchers and photoconvertible tags, which are promising for discriminating FAST variants.

GLOBAL POSITIONING SYSTEM STUDIES OF EQUATORIAL SCINTILLATIONS [PDF]
, 1998 The Global Positioning System (GPS) satellites provide an extensive array of beacon signals for probing the ionosphere. Studies of ionospheric propagation at the GPS L band frequencies (1.2 and 1.6 Hz) are of great interest for proposed communications ...

Excitation‐Selective Hydrochromic Upconversion in Zero‐Dimensional Metal Halides
Advanced Science, EarlyView.Excitation wavelength dictates whether moisture speaks. In zero‐dimensional metal halides, the same humidity leaves the upconversion emission unchanged under 980 nm excitation yet triggers a distinct green‐to‐red shift under 1550 nm. This excitation‐selective hydrochromism, governed by the absorption at each wavelength, enables stimulus‐dependent ...

RADIO STAR SCINTILLATIONS AND THE IONOSPHERE
, 1955 The observed intensity at the surface of the earth of radiation at a frequency of 50 Mc./s. from a radio star has been studied. A relationship is shown to exist between the fluctuations, or scintillations, in this observed radiation intensity and the ...
