A K‐band eight‐element reconfigurable phased‐array receiver with high Tx‐band rejection

IET Microwaves, Antennas & Propagation
A K‐band eight‐element phased‐array receiver is proposed, featuring a reconfigurable beam count and high Tx‐band rejection, tailored for satellite communication applications. By precisely designing the inter‐stage and output matching networks of the four‐

Instrument uncertainties of network-suitable ground-based microwave radiometers: overview, quantification, and mitigation strategies [PDF]

Atmospheric Measurement Techniques
To enhance observations of the atmospheric boundary layer (ABL), the European Meteorological Network (EUMETNET), and the Aerosol, Clouds, and Trace Gases Research Infrastructure (ACTRIS) are currently collaborating to establish networks of microwave ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

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

FEBS 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 ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

FEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Development of a low-noise 1 × 3 mosaic HgCdTe camera with high-precision thermal and flatness control for K-band imaging

AIP Advances
The K-band (2.0–2.4 μm) is crucial for observing astrophysical processes obscured by interstellar dust, such as star formation and active galactic nuclei.

High K bands in mid-supershell nuclei

Acta Physica Polonica B : Elementary Particle Physics, Nuclear Physics, Statistical Physics, Theory of Relativity, Field Theory, 2002
The spectrum of prompt conversion electrons emitted by excited 254No nuclei has been measured, revealing discrete lines arising from transitions within the ground state band. A striking feature is a broad distribution that peaks near 100 keV and comprises high multiplicity electron cascades, probably originating from M1 transitions within rotational ...
