Remarks on vacuum state and uniqueness of concentration process

Electronic Journal of Differential Equations, 2008
We give two examples of nonuniqueness of generalized solutions of pressureless gas dynamics systems. In both of these examples, the presence of the Dirac delta-function leads to nonuniqueness.

A novel method for clean and efficient separation of azeotropic alloy: Vacuum distillation-multistage condensation of silver-indium alloy

Results in Engineering
Silver indium (Ag-In) alloy is a kind of multifunctional material, and recovery of Ag-In alloy can bring significant economic benefits. There are azeotropic points in Ag-In alloy, which cannot be separated by conventional vacuum distillation.

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

FEBS 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.

Study on the geometric structure and stability of AlnMgn (n = 2–12) clusters using density functional theory

Materials Research Express, 2021
In this study, density functional theory was used to investigate the Al _n Mg _n (n = 2–12) clusters on a microscopic scale. The stable structure of clusters was determined and used as the interaction energies parameter in Wilson equation to deepen the ...

Spectrum of modular Hamiltonian in the vacuum and excited states [PDF]

Journal of High Energy Physics, 2019
Abstract We study the non-zero eigenmodes for the modular Hamiltonian in the context of AdS3/CFT2. We show how to perturbatively construct zero eigenmodes for the modular Hamiltonian of the class of excited states constructed in [38], using information about the vacuum non-zero eigen modular modes.

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

FEBS 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 ...

Protocol for quantifying miRNA trafficking across the endosomal membrane

FEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

PERFORMANCE OF VACUUM INSULATIONS FOR USE IN LIQUID HYDROGEN SYSTEMS UNDER STEADY STATE AND LOSS OF VACUUM CONDITIONS [PDF]

Reduction of global carbon emissions is pivotal to the future health of the planet. Renewable resources allow for many sectors to be decarbonized if there is a reliable means to store excess energy.
