β-Turn Mimicking Crosslinking Provides Hyperstability and Fast Folding Kinetics for Short Collagen Triple Helices. [PDF]

Chembiochem
Collagen triple helices and β‐turns are compatible chemical motifs to fuse based on their identical H‐bond geometry. The resulting collagen triple helices are intramolecularly folded, exhibiting high stability and fast folding kinetics. Besides serving as a scaffold structure for designing short, stable, heterotrimeric collagen triple helices, the bis ...

A Hyperstable Aqueous Zinc-Ion Battery Based on Mo_1.74CT_z MXene. [PDF]

Small
A defect‐engineered Mo1.74CTz MXene‐based zinc‐ion battery achieves high capacity as well as 75% capacity retention and nearly 100% Coulombic efficiency even after up to 100 000 cycles. The mechanism of hyperstability is revealed to be the intrinsic structural stability and abundant vertical holes of the Mo1.74CTz MXene, which contribute to alleviating

Enhanced Vigilance Stability during Daytime in Insomnia Disorder [PDF]

Brain Sciences, 2020
Central nervous hyperarousal is as a key component of current pathophysiological concepts of chronic insomnia disorder. However, there are still open questions regarding its exact nature and the mechanisms linking hyperarousal to sleep disturbance. Here,

Hyperstable alkenes: are they remarkably unreactive? [PDF]

Chem Sci
Maier and Schleyer first identified in silico that certain cage bicyclic olefins (alkenes) as “hyperstable”, and predicted them to be “remarkably unreactive”. However, this only applies to hydrogenation, as they were observed to undergo oxidation.

Hyperstability of the Fréchet Equation and a Characterization of Inner Product Spaces [PDF]

Journal of Function Spaces and Applications, 2013
We prove some stability and hyperstability results for the well-known Fréchet equation stemming from one of the characterizations of the inner product spaces. As the main tool, we use a fixed point theorem for the function spaces.

On the E-Hyperstability of the Inhomogeneous σ-Jensen’s Functional Equation on Semigroups

Abstract and Applied Analysis, 2023
In this paper, we study the hyperstability problem for the well-known σ-Jensen’s functional equation fxy+fxσy=2fx for all x,y∈S, where S is a semigroup and σ is an involution of S. We present sufficient conditions on E⊂ℝ+S2 so that the inhomogeneous form

Hyperstability of the Drygas Functional Equation [PDF]

Journal of Function Spaces and Applications, 2013
We use the fixed point theorem for functional spaces to obtain the hyperstability result for the Drygas functional equation on a restricted domain. Namely, we show that a function satisfying the Drygas equation approximately must be exactly the solution ...

Disc-associated proteins mediate the unusual hyperstability of the ventral disc in Giardia lamblia.

J Cell Sci, 2020
Giardia lamblia, a widespread parasitic protozoan, attaches to the host gastrointestinal epithelium using the ventral disc, a complex microtubule (MT) organelle.

Hyperstability for a Generalized Class of Pexiderized Functional Equations on Monoids via Páles’ Approach

Mathematics
In this paper, we deduce some hyperstability results for a generalized class of homogeneous Pexiderized functional equations, expressed as ∑ρ∈Γfxρ.y=ℓf(x)+ℓg(y), x,y∈M, which is inspired by the concept of Ulam stability.
