Spiders for rank 2 Lie algebras

open access: yes, 1996
A spider is an axiomatization of the representation theory of a group, quantum group, Lie algebra, or other group or group-like object. We define certain combinatorial spiders by generators and relations that are isomorphic to the representation theories

Spider vision

open access: yesCurrent Biology, 2020
Morehouse provides an overview of spider vision, with an emphasis on the two main eye types found in spiders. Commonalities of form and function among spiders are discussed but also the huge diversity of eyes that are adapted to various ecological niches.

Piezoelectric Stimulation of Neural Cells: Exploring the Synergistic Potential of Hybrid Scaffolds for Enhanced Regeneration

open access: yesAdvanced Materials Interfaces, EarlyView.
Hybrid piezoelectric scaffolds offer a promising route for Central Nervous System regeneration by combining structural and electrical cues to support neural stem cell growth. This review highlights their potential to overcome current challenges in neural tissue engineering by exploring porous hybrid materials, their biological interactions, and ...

Spectral-phase interferometry for direct electric-field reconstruction applied to seeded extreme-ultraviolet free-electron lasers

open access: yes, 2015
We present a setup for complete characterization of femtosecond pulses generated by seeded free-electron lasers (FEL's) in the extreme-ultraviolet spectral region.

Enhanced Thermal Conductivity in Tough and Environmentally Resilient Hydrogels

open access: yesAdvanced Materials Interfaces, EarlyView.
We enhance the thermal conductivity along with mechanical robustness and environmental resilience in hydrogels through a multiscale engineering stategy. ABSTRACT Hydrogels, known for their biocompatibility and responsiveness to external stimuli, are promising candidates for wearable sensors and electronics.

Erstnachweise von Paratrachelas maculatus in Österreich und Deutschland (Araneae, Corinnidae)

open access: yesArachnologische Mitteilungen, 2012
Three adult females of Paratrachelas maculatus (Thorell, 1875) were found inside a house in the south of Vienna, in a cellar in Cologne and in a house in Rüsselsheim. Additional notes on diet in captivity are presented.

Design and construction of a carbon fiber gondola for the SPIDER balloon-borne telescope

open access: yes, 2014
We introduce the light-weight carbon fiber and aluminum gondola designed for the SPIDER balloon-borne telescope. SPIDER is designed to measure the polarization of the Cosmic Microwave Background radiation with unprecedented sensitivity and control of ...

Phase Diagrams Enable Solid‐State Battery Design

open access: yesAdvanced Materials Interfaces, EarlyView.
Batteries are non‐equilibrium devices with inherent thermodynamic driving forces to react at interfaces, regardless of kinetics or operating conditions. Chemical potential mismatches across interfaces are dissipated via interfacial reactions. In this work, it is illustrated how phase diagrams and chemical potential maps predict degradation pathways but
