Testing-based evaluation of matrix polarity effects on electromechanical and piezoresistive responses of CCB–BaTiO

Polymer Testing
Matrix polarity plays a critical role in determining filler organization, conductive network formation, and electromechanical performance in multifunctional rubber composites. This study investigates the influence of matrix polarity of conductive–ceramic

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Dissection of Arabidopsis ADP-Ribosylation Factor 1 function in epidermal cell polarity [PDF]

, 2005
Vesicle trafficking is essential for the generation of asymmetries, which are central to multicellular development. Core components of the vesicle transport machinery, such as ADP-ribosylation factor (ARF) GTPases, have been studied primarily at the ...

Apical/basal polarity : why plant cells do not stand on their heads [PDF]

, 2005
The anatomical terminology that is used to describe the orientation and polarity in the plant body (for distinction indicated here in italics) is based on the consensus agreement that the transition zone between the aerial and the soil-borne part (the ...

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

FEBS 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?

Evolving sensitivity balances Boolean networks [PDF]

, 2012
We investigate the sensitivity of Boolean Networks (BNs) to mutations. We are interested in Boolean Networks as a model of Gene Regulatory Networks (GRNs). We adopt Ribeiro and Kauffman’s Ergodic Set and use it to study the long term dynamics of a BN. We

CDC-42 Interactions with Par Proteins Are Critical for Proper Patterning in Polarization

Cells, 2020
Many cells rearrange proteins and other components into spatially distinct domains in a process called polarization. This asymmetric patterning is required for a number of biological processes including asymmetric division, cell migration, and embryonic ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

When negation is not negation [PDF]

, 2008
In this paper I will discuss the formation of different types of yes/no questions in Serbian (examples in (1)), focusing on the syntactically and semantically puzzling example (1d), which involves the negative auxiliary inversion.
