Mapping Hsp104 interactions using cross‐linking mass spectrometry

open access: yesFEBS Open Bio, EarlyView.
This study examines how cross‐linking mass spectrometry can be utilized to analyze ATP‐induced conformational changes in Hsp104 and its interactions with substrates. We developed an analytical pipeline to distinguish between intra‐ and inter‐subunit contacts within the hexameric homo‐oligomer and discovered contacts between Hsp104 and a selected ...

Investigation of the Uniformity of Gel Shrinkage by Imaging Tracer Particles Using X‐Ray Microtomography

open access: yesAdvanced Engineering Materials, EarlyView., 2023
A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

SOCIO-PSYCHOLOGICAL SPACE OF KOMSOMOLSK-ON-AMUR AMONG YOUNG PEOPLE WITH DIFFERENT MIGRATION INTENTIONS

open access: yesSovremennye Issledovaniâ Socialʹnyh Problem, 2018
The article presents a research of the structure of the socio-psychological space of Komsomolsk-on-Amur among young people with different migration intentions. 130 16–25 year-old residents from Komsomolsk-on-Amur took part in this research.

Zeta functions of spheres and real projective spaces [PDF]

open access: yesarXiv, 2014
We reprove some results about the Minakshisundaram-Pleijel zeta functions of spheres and study their values at nonpositive integers. The results are extended to zeta functions of real projective spaces.

Matrigel inhibits elongation and drives endoderm differentiation in aggregates of mouse embryonic stem cells

open access: yesFEBS Open Bio, EarlyView.
Stem cell‐based embryo models (SCBEMs) are valuable to study early developmental milestones. Matrigel, a basement membrane matrix, is a critical substrate used in various SCBEM protocols, but its role in driving stem cell lineage commitment is not clearly defined.

A lower bound for higher topological complexity of real projective space [PDF]

open access: yesarXiv, 2017
We obtain an explicit formula for the best lower bound for the higher topological complexity, TC_k(P^n), of real projective space implied by mod 2 cohomology.

An approach for coherent periodogram averaging of tilt‐series data for improved contrast transfer function estimation

open access: yesFEBS Open Bio, EarlyView.
The contrast transfer function (CTF) is an imaging aberration that is a major resolution‐limiting factor in cryo‐electron microscopy (cryo‐EM). Precise CTF estimation is key to overcoming this limitation, but is particularly challenging in cryo‐electron tomography (cryo‐ET) data. Here, we present an approach for using geometric information to assist in

A Generalized Palais-Smale Condition in the Fr\'{e}chet space setting

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2018
The Palais-Smale condition was introduced by Palais and Smale in the mid-sixties and applied to an extension of Morse theory to infinite dimensional Hilbert spaces.
