Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

FEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Circuit quantization from first principles

Physical Review Research
Superconducting circuit quantization conventionally starts from classical Euler-Lagrange circuit equations of motion. Invoking the correspondence principle yields a canonically quantized description of circuit dynamics over a bosonic Hilbert space.

Variational principles of second, first and intermediate kinds for non-holonomic mechanics

, 1999
The differential variational principles of second kind for non-holonomic mechanics ore given, from which a number of integral variational principles of second kind are set up. From the latter, the general relation of delta q'-delta q and the general form

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 ...

First principles calculations for the elastic and thermodynamic properties of CrN

四川大学学报. 自然科学版, 2016
In this paper, we investigate the structure and elastic properties of cubic phase CrN using the plane wave pseudopotential density functional theory method. The results coincide well with the experimental and theoretical values.

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

How Damascius Correlates First Principles in Orphic Theology to His Neoplatonic First Principles: Damascius, On First Principles Chapter 123. [PDF]

This paper offers a detailed analysis of Damascius' discourse on Orphic theology in Chapter 123 of On First Principles, focusing on how Damascius correlates the first principles of Rhapsodic and Hieronyman theogonies to his own Neoplatonic ...
