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 ...

Development of a new method for measuring the electric field strength based on a dual electro-induction sensor [PDF]

open access: yesОмский научный вестник
A new method for measuring electric field strength is proposed. The method is based on the mean value measurement method, which uses a dual electroinduction spherical sensor.

Monitoring induced distributed double-couple sources using Marchenko-based virtual receivers

open access: yes, 2019
We aim to monitor and characterize signals in the subsurface by combining these passive signals with recorded reflection data at the surface of the Earth.

Excessive Application of Fertilizer, Agricultural Non-Point Source Pollution, and Farmers’ Policy Choice

open access: yesSustainability, 2019
This paper takes 516 households who planted wheat in Heyang County, Shaanxi Province in 2018, as samples to construct three policy environments: Technological guidance for planting, subsidies for organic fertilizer application, and agricultural tailwater

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 ...

Vibration diagnosis method of multistage gearing to point out ghost noise source with amplitude fluctuation analysis

open access: yesNihon Kikai Gakkai ronbunshu, 2015
Ground gears sometimes brings ‘ghost noise’ whose frequency is non-integer order of mesh frequency and the cause of ghost noise is surface undulation due to manufacturing process. But the undulation is slight and it becomes difficult to detect with tooth

Reconstruction of the equilibrium of the plasma in a Tokamak and identification of the current density profile in real time [PDF]

open access: yes, 2011
The reconstruction of the equilibrium of a plasma in a Tokamak is a free boundary problem described by the Grad-Shafranov equation in axisymmetric configuration.

Three-intensity decoy state method for device independent quantum key distribution with basis dependent errors

open access: yes, 2013
We study the measurement device independent quantum key distribution (MDIQKD) in practice with limited resource, when there are only 3 different states in implementing the decoy-state method and when there are basis dependent coding errors.
