Molecular Spectra and Molecular Structure [PDF]

open access: bronzeNature, 1929
THOSE who contributed to the recent Faraday Discussion on molecular spectra and molecular structure have now sent their written versions to the secretary for publication. Instead of the report we gave of Prof. Barker's explanation of the double Q branch of ammonia at 10.3 μ and 10.7 μ (NATURE, Oct. 12, p. 587), we should like to substitute Prof. Barker'

Quantum Definition of Molecular Structure. [PDF]

open access: yesJ Am Chem Soc, 2023
Molecular structure, a key concept of chemistry, has remained elusive from the perspective of all-particle quantum mechanics despite many efforts. Viewing molecular structure as a manifestation of strong statistical correlation between nuclear positions, we propose a practical method based on Markov chain Monte Carlo sampling and unsupervised machine ...

Mars, a molecule archive suite for reproducible analysis and reporting of single-molecule properties from bioimages

open access: yeseLife, 2022
The rapid development of new imaging approaches is generating larger and more complex datasets, revealing the time evolution of individual cells and biomolecules. Single-molecule techniques, in particular, provide access to rare intermediates in complex,

On the structure of molecular clouds [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2012
We show that the inter-cloud Larson scaling relation between mean volume density and size $ \propto R^{-1}$, which in turn implies that mass $M\propto R^2$, or that the column density $N$ is constant, is an artifact of the observational methods used.

Divergent self-association properties of paralogous proteins TRIM2 and TRIM3 regulate their E3 ligase activity

open access: yesNature Communications, 2022
TRIM E3 ligases are key regulators of numerous cellular functions, yet their mechanism of action remains poorly understood. Here, the authors show that paralogous TRIM2 and TRIM3 adopt different self-association and activity profiles but interact in ...

The antitumor activity of cannabidiol on lung cancer cell lines A549 and H1299: the role of apoptosis

open access: yesBiotechnology & Biotechnological Equipment, 2021
In the recent years, the application of new antitumor drugs has focused on the replacement of conventional chemotherapeutics with compounds derived from natural products.

Benchmarking tomographic acquisition schemes for high-resolution structural biology

open access: yesNature Communications, 2020
Here the authors systematically benchmark cryo-electron tomography acquisition schemes to optimize the attainable resolution for subtomogram averaging, and find that dose-symmetric acquisition with even angular sampling provides a better outcome than ...

Structure of the human marker of self 5-transmembrane receptor CD47

open access: yesNature Communications, 2021
CD47 is a transmembrane receptor involved in the regulation of various signalling pathways and a promising target for immuno-oncology therapeutics. Here, the authors present the crystal structure of full-length human CD47 and provide insights into the ...

On the emergence of molecular structure [PDF]

open access: yesPhysical Review A, 2011
The structure of {a(+/-),a(+/-),b(+/-)}-type Coulombic systems is characterized by the effective ground-state density of the a-type particles, computed via nonrelativistic quantum mechanics without introduction of the Born-Oppenheimer approximation. A structural transition is observed when varying the relative mass of the a- and b-type particles, e.g.,

Adipocyte HIF2α functions as a thermostat via PKA Cα regulation in beige adipocytes

open access: yesNature Communications, 2022
Thermogenic adipocytes maintain body temperature in response to cold, but how this is tuned during cold and re-warming is unclear. Here, the authors show HIF2α inhibits beige adipocyte retention, regulating PKA catalysis to control dynamic adipocyte ...
