The confidence-accuracy relation – A comparison of metacognition measures in lie detection
(2022-04-26)
Previous research has produced mixed results on the question of whether confidence in ad hoc veracity judgments can be used as an indicator of judgment accuracy. These studies have used a variety of measures to analyze the confidence-accuracy relationship; however, they have rarely explicitly addressed why a particular measure was chosen and what its properties are. We theoretically and empirically examined previously used measures of metacognition in lie detection and report the results these measures yielded in ...

Are open-book tests still as effective as closed-book tests even after a delay of 2 weeks?
(2022-04-06)
The present work was conducted to re-examine the findings of Agarwal et al. (Applied Cognitive Psychology, 22(7), 861–876, 2008), which showed that both closed-book tests (with feedback) and open-book tests increased learning outcomes after 1 week compared to simple re-study of the same materials. However, contrary to often found benefits of retrieval practice—which should be more pronounced in closed-book tests—both test conditions proved to be similarly effective. As retrieval practice benefits increase with retention ...

Body scan meditation enhances the autonomous sensory meridian response to auditory stimuli
(2022-05-03)
Autonomous sensory meridian response (ASMR) is a pleasant, tingling sensation on the skin that can be elicited by certain auditory and visual stimuli, with the intertwining of sensory modalities and emotional reactions observable in this phenomenon resembling that of synesthesia. The current study shows that the perception of ASMR-associated tingles can be enhanced by means of a prior mindfulness exercise in which attention is drawn to the body. This finding contributes to a better understanding of the crossmodal ...

3DWoodWind: robotic winding processes for material-efficient lightweight veneer components
(2022-03-25)
Winding processes are known from fiber composite technology for highly resistance lightweight components for aviation. These fiber-based processes work predominantly with synthetic composites made of carbon or glass fibers. For the construction industry, these additive processes are very promising and resource-efficient building processes, but they are still hardly used in timber construction despite the very high level of digitalization and technical development. The 3DWoodWind research project uses a continuous ...

Stream-based active learning for sliding windows under the influence of verification latency
(2021-11-18)
Stream-based active learning (AL) strategies minimize the labeling effort by querying labels that improve the classifier’s performance the most. So far, these strategies neglect the fact that an oracle or expert requires time to provide a queried label. We show that existing AL methods deteriorate or even fail under the influence of such verification latency. The problem with these methods is that they estimate a label’s utility on the currently available labeled data. However, when this label would arrive, some of ...

Sulfur transfer and activation by ubiquitin-like modifier system Uba4•Urm1 link protein urmylation and tRNA thiolation in yeast
(2016-10-24)
Urm1 is a unique dual-function member of the ubiquitin protein family and conserved from yeast to man. It acts both as a protein modifier in ubiquitin-like urmylation and as a sulfur donor for tRNA thiolation, which in concert with the Elongator pathway forms 5-methoxy-carbonyl-methyl-2-thio (mcm5s2) modified wobble uridines (U34) in anticodons. Using Saccharomyces cerevisiae as a model to study a relationship between these two functions, we examined whether cultivation temperature and sulfur supply previously ...

Dietary Quality of Women of Reproductive Age in Low-Income Settings: A Cross-Sectional Study in Kyrgyzstan
(2022-01-11)
Dietary diversity and adequate nutrient intake are essential for conducting a healthy life. However, women in low-income settings often face difficulties in ensuring dietary quality. This research assessed relationships between the dietary diversity, nutrient adequacy, and socio-economic factors among women of reproductive age (WRA) in Kyrgyzstan. A cross-sectional study was undertaken in four locations, including two rural and two urban areas in the north and south of Kyrgyzstan. A survey with pre-coded and open-ended ...

Beyond spikes: Multiscale computational analysis of in vivo long-term recordings in the cockroach circadian clock
(2019-09-23)
The circadian clock of the nocturnal Madeira cockroach is located in the accessory medulla, a small nonretinotopic neuropil in the brain’s visual system. The clock comprises about 240 neurons that control rhythms in physiology and behavior such as sleep-wake cycles. The clock neurons contain an abundant number of partly colocalized neuropeptides, among them pigment-dispersing factor (PDF), the insects’ most important circadian coupling signal that controls sleep-wake rhythms. We performed long-term loose-patch clamp ...

Reversible Photo-Induced Reshaping of Imprinted Microstructures Using a Low Molecular Azo Dye
(2022-01-31)
A blend of low molecular azo glass (AZOPD) and polystyrene (PS) were used for the systematic investigation of photo-induced stretching and recovery of nanoimprinted structures. For this purpose, light and heat was used as recovery stimuli. The AZOPD/PS microstructures, fabricated with thermal nanoimprint lithography (tNIL), comprises three different shapes (circles, crosses and squares) and various concentrations of AZOPD fractions. The results show a concentrationdependent reshaping. Particularly the sample with 43 ...

Heavy Metals and Polycyclic Aromatic Hydrocarbons in Urban Leaf Litter Designated for Combustion
(2017-03-03)
Vast amounts of leaf litter have to be disposed of by city administrations. This biomass has the potential for energy conversion, but contamination with pollutants can adversely affect this usage. We investigated leaf litter samples from the city of Kassel by analyzing their heavy metal and polycyclic aromatic hydrocarbon (PAH) concentrations. Leaf samples were indeed contaminated with heavy metals and PAHs and contamination was influenced by provenience and collection technique. A simple cleaning system of washing ...
