Tropospheric Atmospheric Heterogeneities of ALOS-2 Interferograms in the Greater Bay Area

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
L-band advanced land observing satellite-2 (ALOS-2) images are a good source of radar data with better coherence than C-band images. However, significant ionospheric effects are often associated with L-band interferograms.

Adaptive high-performance velocity evaluation based on a high resolution time-to-digital converter [PDF]

open access: yes, 2008
In this paper, an improved method is presented to derive the velocity information in a pulse-number measurement/time-duration-type digital tachometer by processing its pulse train.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Ab Initio Intermolecular Potential of Ar–C2H2 Refined Using High-Resolution Spectroscopic Data

open access: yes, 2013
The high-resolution infrared spectra of the ν1 + ν3 (2CH) band of the Ar–C2H2 complex has been recorded from 6544 to 6566 cm–1. The previously reported Ka = 1 ← 0, 2 ← 1, and 0 ← 1 subbands were observed and the Ka = 1 ← 2, 2 ← 3, and 3 ← 2 subbands were

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

High resolution muon tracking with resistive plate chambers [PDF]

open access: yes, 2012
Following their introduction in the physics community in the early '80s the use of Resistive Plate Chambers (RPCs) as charged particles detectors has constantly increased. Low cost per unit area, good time resolution and easy of operation are some of the

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
