Universal adhesives - a new direction in the development of adhesive systems

open access: yesČeská Stomatologie a Praktické Zubní Lékařství, 2020
Objectives: In the past decade, many new adhesive systems labeled as universal were introduced. Their common characteristic is that they can be applied to hard dental tissues either in self-etch or etch-and-rinse mode, and they are also able to bond to ...

Logarithmic moments of characteristic polynomials of random matrices

open access: yes, 1999
In a recent article we have discussed the connections between averages of powers of Riemann's $\zeta$-function on the critical line, and averages of characteristic polynomials of random matrices.

Assessing Cognitive Functioning in Children With Brain Tumors: Interaction of Neighborhood Social Determinants of Health and Neurological Risk

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background This study investigated how neighborhood‐level social determinants of health (SDOH), including redlining and neurological risk, interact to influence cognitive outcomes in children treated for brain tumors (CTBT). Methods A retrospective chart review of 161 CTBT aged 5–17 was conducted.

An effective Arakelov-theoretic version of the hyperbolic isogeny theorem

open access: yes, 2015
For an integer $e$ and hyperbolic curve $X$ over $\overline{\mathbb Q}$, Mochizuki showed that there are only finitely many isomorphism classes of hyperbolic curves $Y$ of Euler characteristic $e$ with the same universal cover as $X$.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Shear viscosity and spin sum rules in strongly interacting Fermi gases

open access: yes, 2013
Fermi gases with short-range interactions are ubiquitous in ultracold atomic systems. In the absence of spin-flipping processes the number of atoms in each spin species is conserved separately, and we discuss the associated Ward identities.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Church-Theological Foundations of Early Ukrainian Catholicism (XI-XII centuries)

open access: yesУкраїнське Pелігієзнавство, 2004
Early Ukrainian Christianity (XI-XII centuries) was based, as we know, on the one and only faith of Christ, which taught the right (that is, the "right") to believe in Christ and to rightly glorify Him in the presence of various false heretical teachings
