Chiral Cycloparaarylenes Incorporating Binaphthyl Units: Dramatic Effects of Peripheral Functionalization on (Chir)Optical Properties

Chemistry – A European Journal, EarlyView.
Chiral cycloparaarylenes (CPAs) incorporating binaphthyl units were synthesized. The methoxy‐substituted and methylenedioxy‐bridged systems adopt D3‐ and C3/C1‐symmetric structures, respectively. They exhibited distinct solid‐state emission and aggregation‐induced emission enhancement (AIEE).

Potenzial außerschulischer Lernorte zur Förderung transversaler Kompetenzen

CHEMKON, EarlyView.
Transversale Kompetenzen wie Kommunikation, Kollaboration, kritisches Denken und Entscheidungsfindung sind zentral für schulischen Erfolg, berufliche Handlungsfähigkeit und gesellschaftliche Teilhabe. Dennoch werden diese Kompetenzen im schulischen Kontext bislang häufig nur niederschwellig gefördert.

Effects of Trace Elements and Vitamins on the Synthesis of Steroid Hormones in Follicular Granulosa Cells of Yak

Veterinary Sciences
Yak (Bos grunniens), a special breed of cattle on the Qinghai–Tibet Plateau, has low fertility due to nutritional deficiency, especially the trace elements. The steroid hormones estradiol (E2) and progesterone (P4) synthesized by yak follicular granulosa

How to Milk a Yak: Embodied Learning with Yaks in Practice

Suomen Antropologi: Journal of the Finnish Anthropological Society
This essay is based on an ethnographic study at a self-subsistence-oriented yak herding village in Tibet (Tibetan Autonomous Region, China). I demonstrate how the social-biophysical profile and the life history of the researcher influences the research process–that is, how the individuality of the researcher’s body (e.g., gender, physical fitness ...

Reinforcement learning‐enhanced adaptive sliding mode controller for underground articulated vehicles trajectory tracking

Deep Underground Science and Engineering, EarlyView.
RL‐SMC couples a reinforcement learning agent with a sliding mode controller, where the agent online‐modulates the sliding mode parameters according to the vehicle's tracking state. A curvature‐aware preview term is further embedded to shift control from reactive correction to proactive maneuvering, enabling the articulated vehicle to anticipate sharp ...

Assessing the accuracy and stability of variable importance in species distribution modelling algorithms through sample perturbations

Ecography, EarlyView.
Variable importance derived from species distribution modelling (SDM) is widely used to identify key environmental drivers of species distributions. However, the reliability of these inferences has rarely been systematically evaluated, particularly with respect to their sensitivity to individual occurrences.

Assessment of the effects of microwave‐produced biodiesel blends on electric generator performance and emissions

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Biodiesels are emerging as alternatives to diesel fuel. However, to be a feasible solution, biodiesels must meet strict criteria including high efficiency and minimal environmental impact. The current study focuses on evaluating ethyl ester biodiesel and its blends with diesel fuel to assess their potential.
