Modeling of Hovering Type AUV Test Bed with Four Thrusters and Two Hulls Design

, 2010
This paper proposes a design of hovering Type Autonomous Underwater Vehicle (AUV) using four thruster and two hulls. The state vector representation of AUV kinematics and the mathematical modeling of their dynamics of motion are presented.

An experimental examination of dispersal decisions made by flight‐capable heteropteran insects in urban stormwater pond conditions

Ecological Entomology, EarlyView.
Salty conditions in urban stormwater ponds can influence dispersal timing in species‐specific ways for actively dispersing aquatic heteropteran insects. Assaying multiple aspects of dispersal propensity, Hesperocorixa obliqua emigrated earlier in stormwater pond conditions while overall probabilities remained unchanged; Notonecta undulata emigration ...

ALOX15 mediates thrombin‐induced myristoylation, trafficking, and interaction of protease‐activated receptors, leading to platelet activation and hemostasis

The FEBS Journal, EarlyView.
The role of PARs in platelet function is fairly known; however, the underlying mechanisms are not fully understood. We report that thrombin myristoylates PAR4 in mouse platelets and PAR1 and PAR4 in human platelets, facilitating their membrane transport and interaction, leading to PAR3/4 heterodimers in mice and PAR1/4 heterodimers in humans.

Ecological controls on density, diversity and community structure of Polar Megabenthos

, 2005
Polar deep water environments are poorly studied. This thesis investigates fundamental questions as to the nature of controlling factors on megabenthic communities as well as the diversity, densities and distributions of organisms present.The deep (1000 ...

Integrative taxonomy reveals four new species of the armoured catfish genus Pareiorhina (Siluriformes: Loricariidae) from the upper Paraná River basin, Brazil

Journal of Fish Biology, EarlyView.
Abstract Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...
