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 ...

The Characterization Of Saw Coupling Factor From Paired Idt Insertion Loss Measurements

open access: yes, 2002
The extent to which the measured transmission insertion loss between paired identical unapodized IDTs can be correlated to the coupling factor of a piezoelectric substrate or piezo-film layer is considered in this paper.

Insertion loss and misalignment tolerance in multimode tapered waveguide bends [PDF]

open access: yes, 2008
Experimental measurements of laterally tapered multimode waveguide bends fabricated photolithographically on FR4 printed circuit board establish that the product of the mean insertion loss (in linear units) and the mean source misalignment tolerance is a

Analysis of the Three-dimensional Transient Temperature Field of Rubber Parts of High Elastic Coupling

open access: yesJixie chuandong, 2018
The temperature distribution of rubber parts of high elastic coupling will affect lifetime of product and reliability of the shaft system. The heat transfer theory and finite element method of uncoupling analysis is adopted to analyze the change process ...

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.

Wafer-Scale Experimental Determination of Coupling and Loss for Photonic Integrated Circuit Design Optimisation

open access: yesPhotonics
We investigate integrated silicon ring resonators with regard to the influence of design parameters and intra-wafer variations. First, we show the effect of different ring radii and gaps between ring and bus waveguide on optical properties (peak width ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Mode analysis and Q-factor enhancement due to mode coupling in rectangular resonators

open access: yes, 2007
Modes in rectangular resonators are analyzed and classified according to symmetry properties, and quality factor (Q-factor) enhancement due to mode coupling is observed. In the analysis, mode numbers p and q are used to denote the number of wave nodes in
