Multi-Frequency Polarisation Measurements of PACO Radio Sources

open access: yes, 2016
Active Galactic Nuclei (AGN) inner regions, poorly characterized so far at frequencies above 20 GHz, can now be studied through their emission and magnetic field properties by means of multi-frequency and multi-epoch polarimetry at centimetric and ...

Multi-Omic Factors Associated with Frequency of Upper Respiratory Infections in Developing Infants

open access: yes, 2023
Susceptibility to upper respiratory infections (URIs) may be influenced by host, microbial, and environmental factors. We hypothesized that multi-omic analyses of molecular factors in infant saliva would identify complex host-environment interactions ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Frequency-comb-induced radiation pressure force in dense atomic clouds

open access: yes, 2021
We investigate the frequency comb induced radiation pressure force acting on a cloud of cold $^{87}$Rb atoms. Reduction and spectral broadening of the frequency comb force are observed as the cloud's optical thickness is increased.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

open access: yesFEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Multi-group frequency hopping OFDMA based on statistical multiplexing [PDF]

open access: yes, 2008
In this paper, the multi-group frequency hopping OFDMA (MG-FH OFDMA) based on the statistical multiplexing is proposed for the downlink cellular system. Compared with the existed random frequency hopping OFDMA (RFH-OFDMA) system utilizing the statistical
