Transitive Arcs in Planes of Even Order

open access: yesEuropean Journal of Combinatorics, 1996
In this paper, the author classifies all arcs in \(\mathrm{PG}(2,q)\), \(q\) even, which are stabilized by a transitive, irreducible (i.e., fixing neither a point nor any line) group \(G\), with the additional assumption that \(G\) does not stabilize a triangle in \(\mathrm{PG}(2,q)\) or in the extension \(\mathrm{PG}(2,q^3)\).

Even order snake resonances [PDF]

open access: yesProceedings of International Conference on Particle Accelerators, 2002
We found that the perturbed spin tune due to the imperfection resonance plays an important role in beam depolarization at snake resonances. We also found that even order snake resonances exist in the overlapping intrinsic and imperfection resonances. Due to the perturbed spin tune shift of imperfection resonances, each snake resonance splits into two. >

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

New oscillation theorems for a class of even-order neutral delay differential equations

open access: yesAdvances in Difference Equations, 2021
In this work, we study the oscillatory behavior of even-order neutral delay differential equations υ n ( l ) + b ( l ) u ( η ( l ) ) = 0 $\upsilon ^{n}(l)+b(l)u(\eta (l))=0$ , where l ≥ l 0 $l\geq l_{0}$ , n ≥ 4 $n\geq 4$ is an even integer and υ = u + a

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

On Buekenhout-Metz unitals of even order

open access: yesEuropean Journal of Combinatorics, 1992
A unital is a \(2-(n^ 3+1,n+1,1)\) design. The classical example of a unital is the set of absolute points in a projective plane \(\text{PG}(2,n^ 2)\) with respect to a unitary polarity, blocks being the sets of points on secant lines. A class of unitals, including the classical ones, can be constructed inside \(\text{PG}(2,n^ 2)\) by a method due to ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions

open access: yesFEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...
