Spring‐Like Behavior in [8]Helicene Diimides: How Helical Pitch Governs Optical Anisotropy and Electronic Conjugation

open access: yesAngewandte Chemie International Edition, EarlyView.
Bridging the imide nitrogen atoms of [8]helicene diimides with different alkyl chains allows for precise control over the helical pitch of their backbones. This has a profound impact on the molecular packing, chiroptical properties, and through‐space electronic conjugation of the molecules.

Efficient unified Montgomery inversion with multibit shifting [PDF]

open access: yes, 2004
Computation of multiplicative inverses in finite fields GF(p) and GF(2/sup n/) is the most time-consuming operation in elliptic curve cryptography, especially when affine co-ordinates are used.

Resolving Localized Plasmonic and Photonic Modes of Gold Nanosponges via Cathodoluminescence Spectroscopy

open access: yesAdvanced Physics Research, EarlyView.
Cathodoluminescence spectroscopy of gold nanosponges, together with polarimetry experiments, demonstrates the presence of a network of randomly positioned dipolar plasmonic resonances with a spatial extent of only a few nanometres. Abstract Localizing optical fields at deep sub‐wavelength scales has applications in ultra‐strong light‐matter ...

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

open access: yesThe Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin

open access: yesThe Anatomical Record, EarlyView.
Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.
