Stein kernels and moment maps [PDF]

open access: yesThe Annals of Probability, 2019
We describe a construction of Stein kernels using moment maps, which are solutions to a variant of the Monge-Ampère equation. As a consequence, we show how regularity bounds on these maps control the rate of convergence in the classical central limit theorem, and derive new rates in Kantorovitch-Wasserstein distance in the log-concave situation, with ...

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

THE NEW MAP OF HEREDITARY CAPTAINCIES OF BRAZIL

open access: yesRevista Brasileira de Cartografia, 2015
This paper presents a new map of the Hereditary Captaincies at the moment of their creation (1534-1536), which differs from the traditional map proposed by Varnhagen in 1854, has remained until now.

Inclination Effect on Observational Identification of Outflow Rotation in Magnetohydrodynamics Simulations

open access: yesThe Astrophysical Journal
We investigate the observational signatures of outflow rotation in protostellar systems using magnetohydrodynamics simulations of protostellar evolution with radiative transfer and synthetic observation. The velocity gradient perpendicular to the outflow

Wireless magnetic-based closed-loop control of self-propelled microjets.

open access: yesPLoS ONE, 2014
In this study, we demonstrate closed-loop motion control of self-propelled microjets under the influence of external magnetic fields. We control the orientation of the microjets using external magnetic torque, whereas the linear motion towards a ...

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Study of Ship Accident Factors and Ship Routes Correlation

open access: yesScientific Journal of Gdynia Maritime University, 2018
The sailing safety was a very important issue that had to be solved in Indonesia. There were accidents causing victims and material losses caused by ship operator’s ignorance and less awareness on safety.
