Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

open access: yesFEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Frictional cooling of positively charged particles

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2012
One of the focuses of research and development towards the construction of a muon collider is muon beam preparation. Simulation of frictional cooling shows that it can achieve the desired emittance reduction to produce high-luminosity muon beams. We show

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

open access: yesFEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

DIFFRACTIVE SCATTERING OF CHARGED PARTICLES

open access: yesВестник. Серия физическая, 2010
Studied the scattering of nucleons on nucleons at high energies; studied the angular dependence under the elastic scattering of hadrons. In details considered the scattering of nucleons by deuterons.

The May 2024 Superstorm Coronal Mass Ejections as Observed by the Psyche Gamma‐Ray and Neutron Spectrometer

open access: yesSpace Weather
We report new measurements of high‐energy protons ejected by the sun during the May 2024 Ganon superstorm. Our observations were made by the Neutron Spectrometer (NS) on the Psyche spacecraft, which was located at a solar distance of approximately 2 AU ...

On fast charged particles scattering in a thin crystalline undulator

open access: yesPhysics Letters B, 2019
The scattering of fast charged particles in a thin silicon crystalline undulator is considered under conditions when all the particles of the beam undergo above-barrier motion with respect to the bent crystalline atomic planes. The consideration is based

Mean volume reflection angle

open access: yesPhysical Review Accelerators and Beams, 2020
The mean volume reflection angle of a high-energy charged particle passing through a bent crystal is expressed as an integral involving the effective interplanar potential over a single crystal period.

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

open access: yesFEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

Effective charge of colloidal particles [PDF]

open access: yesThe Journal of Chemical Physics, 2004
A new dynamical definition of the effective colloidal charge, especially suitable for the Monte Carlo and Molecular-dynamics simulations, is proposed. It is shown that for aqueous colloidal suspensions containing monovalent counterions the “dynamical” effective charge agrees perfectly with the “statistical” effective charge calculated using the ...
