Measurement of the linear thermo-optical coefficient of Ga$_{0.51}$In$_{0.49}$P using photonic crystal nanocavities

, 2017
Ga$_{0.51}$In$_{0.49}$P is a promising candidate for thermally tunable nanophotonic devices due to its low thermal conductivity. In this work we study its thermo-optical response. We obtain the linear thermo-optical coefficient $dn/dT=2.0\pm0.3\cdot 10^{-

Roundtrip matrix method for calculating the leaky resonant modes of open nanophotonic structures [PDF]

, 2014
We present a numerical method for calculating quasi-normal modes of open nanophotonic structures. The method is based on scattering matrices and a unity eigenvalue of the roundtrip matrix of an internal cavity, and we develop it in detail with ...

Association Between Healthy Lifestyle Behaviors and Mental Health Symptoms in Children With Autism and ADHD: A Latent Profile Analysis

Autism Research, EarlyView.
ABSTRACT Healthy lifestyle behaviors, including physical activity, screen time, sleep, and diet quality, are important determinants of mental health, yet little is known about how these behaviors cluster among children with neurodevelopmental disorders.

Constructing a partially transparent computational boundary for UPPE using leaky modes [PDF]

, 2019
In this paper we introduce a method for creating a transparent computational boundary for the simulation of unidirectional propagation of optical beams and pulses using leaky modes. The key element of the method is the introduction of an artificial-index

Hidden O‐Deglycosylation Activity Triggers O → C Rearrangement for Aryl Di‐C‐Glucoside Formation by the C‐Glycosyltransferase From Fortunella crassifolia

Biotechnology and Bioengineering, EarlyView.
Here, we uncovered an unexpected O‐deglycosylation activity of the C glycosyltransferase (FcCGT), forming phloretin (1) from phloretin 2'‐O‐glucoside (2). In the presence of UDP, FcCGT catalyzes the O→C rearrangement to yield nothofagin (3). Upon additional UDP‐glucose, further C‐glycosylation occurs, forming phloretin 3',5'‐di‐C‐glucoside (4 ...

Drivkraft og dynamik i de trøstende samspil i børnehaven

Nordisk Barnehageforskning
Resumé Trøst er et velkendt og centralt greb, som de voksne har i brug i børnehavens dagligliv med børnene, mens det som begreb sjældent er i brug i pædagogikken og slet ikke findes i de myndighedsdokumenter, der regulerer daginstitutionssektoren. Dette

A carbohydrate approach for the formal total synthesis of (−)-aspergillide C

Beilstein Journal of Organic Chemistry, 2014
An enantioselective formal total synthesis of aspergillide C is accomplished using commercially available tri-O-acetyl-D-galactal employing a Ferrier-type C-glycosylation, utilizing a Trost hydrosilylation and protodesilylation as key reactions.

The politics of impact: How political ideology shapes perceptions of the environmental impact of individual actions

Journal of Consumer Psychology, EarlyView.
Abstract Although consumers who engage in the same sustainable behaviors objectively have the same environmental impact, this research finds that people's perceptions of that impact are subjective and systematically shaped by political ideology. Seven studies demonstrate that conservatives tend to perceive their sustainable actions to have less of a ...

Congenital aniridia: European COST action ANIRIDIA‐NET guidelines for diagnosis, management and care

Acta Ophthalmologica, EarlyView.
Abstract Congenital aniridia is a rare ocular disorder affecting the majority of eye structures and can be associated with systemic manifestations. The main visible phenotypic characteristic is the partial or complete absence of the iris; however, foveal hypoplasia is a more frequent and reliable clinical sign. Other ocular comorbidities are associated

Not that different after all: Pro‐environmental social norms predict pro‐environmental behaviour (also) among those believing in conspiracy theories

British Journal of Psychology, EarlyView.
Abstract Social norms are powerful predictors of pro‐environmental behaviour. At the same time, conspiracy beliefs are prevalent that can reduce individuals' efforts to act pro‐environmentally and might impede the influence of social norms. Across three cross‐sectional studies in three countries (Germany, UK, US; total N = 1037), we investigated the ...
