Compact, efficient ultra-wide tunable laser with reduced thermal crosstalk.

Future optical communication systems will exploit increasingly wide optical wavelength bands to continue scaling capacity per installed fiber. Currently, optical components such as tunable lasers and modulators are designed to operate in a single wavelength band only and multiple designs are therefore needed for a single system. Improved tunable lasers operating seamlessly over these wider bands would both simplify system deployment and management.

The Presence of a Parasite in the Head Tissues of a Threatened Fish (, Terapontidae) from South-Eastern Australia.

The silver perch, (Mitchell) (Terapontidae) is a freshwater fish, endemic to the Murray-Darling river system in south-eastern Australia. Population declines have led to the fish being listed as critically endangered by the Australian Government. Knowledge about parasites and diseases of wild populations of freshwater fish are limited in Australia.

Leveraging mass detection to simultaneously quantify surfactant content and degradation mode for highly concentrated biopharmaceuticals.

Non-ionic surfactants are commonly used in parenteral protein formulations and include polysorbate 20, polysorbate 80 and poloxamer188. Recently, quantification and characterization of surfactants has generated considerable interest due to their connection to visible particle formation, a critical quality attribute for parenteral formulations. Typically, surfactant quantification is performed by mixed mode chromatography with evaporative light scattering detection (ELSD) or charged aerosol detection (CAD).

Bold-shy personality traits of globally invasive, native and hatchery-reared fish.

Bold behaviour of non-native species is hypothesized to facilitate invasion success, yet extreme boldness in wild and domesticated animals can be maladaptive. The purpose of this study was to compare individual behaviour among Australian native hatchery-reared ( = 33) and wild ( = 38) Murray cod () with invasive common carp (; = 30). Three laboratory tests measured individual behaviour: (1) emergence from a shelter, (2) exploration of a novel environment, and (3) approaching a predator.
