Verständnis und Optimierung der Singulett‐Triplett‐(S1/T1)‐Energiedifferenzen in planaren organischen Chromophoren

open access: yesAngewandte Chemie, EarlyView.
Ein neues Modell zur Optimierung der Singulett‐Triplett‐(S1/T1)‐Energiedifferenzen wurde entwickelt, das auf elektrostatischen Wechselwirkungen der Übergangsdichte basiert. Drei klar anwendbare Regeln zur Maximierung der Singulett‐Triplett‐Energiedifferenzen werden abgeleitet: Minimierung der Gesamtzahl an π‐Elektronen, Lokalisierung der π‐Elektronen ...

When mites attack: domestic mites are not just allergens [PDF]

open access: yesParasites & Vectors, 2014
Domestic mite species found in indoor environments and in warm or tropical regions are well known for causing allergic disorders. However, little is known about human acariasis, in which mites invade and parasitize the human body in various tissues from the gastrointestinal tract to the lung.

Konvergenter Aufbau Homo‐ und Heterotypischer Ubiquitinketten aus funktionaliserten, exprimierten Monomeren mittels Thiol‐En‐Chemie

open access: yesAngewandte Chemie, EarlyView.
Die Erzeugung funktionalisierter Ubiquitinbausteine mittels Expression in E. coli bietet Zugang zu verschiedenen Di‐, Tri‐ und Tetra‐Ubiquitinketten. Photoinitiierte Thiol‐En‐Klickreaktionen werden dabei in Kombination mit einer Maskierungs‐ und Schutzgruppenstrategie zum kontrollierten Aufbau von Ubiquitinketten sowie zur Semisynthese von ...

Propensity score analysis with partially observed confounders: how should multiple imputation be used? [PDF]

open access: yesarXiv, 2016
Inverse probability of treatment weighting (IPTW) is a popular propensity score (PS)-based approach to estimate causal effects in observational studies at risk of confounding bias. A major issue when estimating the PS is the presence of partially observed covariates.

An Overview of Microfluidic‐Assisted Strategies for Synthesis and Applications of Molecularly Imprinted Polymers

open access: yesAnalysis &Sensing, EarlyView.
Sensor design increasingly focusses on miniaturized systems deployed directly at the point of need. For this purpose, microfluidics ensures low‐cost systems that can handle small sample volumes and molecularly imprinted polymers provide rugged, cost‐effective recognition.

“Even Though We Have Different Colors, We Are All Equal Here”: Immigrants building a sense of community and wellbeing through sport participation

open access: yesJournal of Community Psychology, Volume 51, Issue 1, Page 201-218, January 2023., 2023
Abstract Although there are several studies reporting the beneficial role of sports in immigrant health, more research is needed to understand whether and how these activities can guide the psychological sense of community (SOC) and well‐being outcomes.

High‐throughput behavioral phenotyping of tiny arthropods: Chemosensory traits in a mesostigmatic hematophagous mite

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 339, Issue 1, Page 46-62, January 1, 2023., 2023
We validated a new high‐throughput system based on nanocomputers connected to cameras automatically tracking movements of single mites. Our results confirm the existence of a volatile pheromone deposited by D. gallinae and attractive to conspecifics.
