Biosensing with Fluorescent Carbon Nanotubes. [PDF]

open access: yesAngew Chem Int Ed Engl, 2022
Optical biosensors are important tools for basic research and non‐invasive diagnostics. Carbon nanotubes are versatile near‐infrared fluorescent and non‐bleaching materials that can be chemically functionalized to detect a broad variety of biomolecules.

Percutaneous Repair or Medical Treatment for Secondary Mitral Regurgitation

open access: yesNew England Journal of Medicine, 2018
BACKGROUND In patients who have chronic heart failure with reduced left ventricular ejection fraction, severe secondary mitral‐valve regurgitation is associated with a poor prognosis. Whether percutaneous mitral‐valve repair improves clinical outcomes in

A randomised controlled trial testing the rebound‐preventing benefit of four days of prednisolone during the induction of oclacitinib therapy in dogs with atopic dermatitis

open access: yesVeterinary Dermatology, Volume 34, Issue 2, Page 99-106, April 2023., 2023
Background – A rebound of pruritus occasionally occurs after oclacitinib dose reduction in dogs with atopic dermatitis (AD). Objectives – To determine whether an initial 4‐day course of prednisolone decreases the probability of a pruritus rebound after reducing the frequency of oclacitinib administration.

Can regional policies shape migration flows?

open access: yesPapers in Regional Science, Volume 101, Issue 3, Page 515-536, June 2022., 2022
Abstract Our empirical analysis focuses on the effect of regional policies on migration attraction factors in Europe. We employ a regression discontinuity design to assess the causal relationship between the reception of large amounts of public funds and migration flows in the EU‐15 regions. In highly‐subsidised regions, we find a large increase in the

Family risk and early attachment development: The differential role of parental sensitivity

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 43, Issue 2, Page 340-356, March 2022., 2022
Abstract Family risks are known to be detrimental to children's attachment development. This study investigated whether parental sensitivity plays different roles in early attachment development in the context of risk: Sensitivity was hypothesized to mediate risk effects on attachment, as well as a moderator that shapes the relation between risk and ...

Proof of some properties of transfer using noncommutative determinants [PDF]

open access: yes, 2018
A transfer is a group homomorphism from a finite group to an abelian quotient group of a subgroup of the group. In this paper, we explain some of the properties of transfers by using noncommutative determinants.

Basic Operations on Supertropical Quadratic Forms

open access: yesDocumenta Mathematica, 2017
In the case that a module V over a (commutative) supertropical semiring R is free, the R-module Quad(V ) of all quadratic forms on V is almost never a free module.

Bipartite Graphs Associated with Pell, Mersenne and Perrin Numbers

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019
In this paper, we consider the relationships between the numbers of perfect matchings (1-factors) of bipartite graphs and Pell, Mersenne and Perrin Numbers.
