A communication system between two autonomous micro air vehicles is proposed. Laser communication offers advantages in range, power, and bandwidth when line of sight is available. Beamsteering is accomplished using gyro-stabilized MEMS micromirrors. A custom CMOS smart-pixel imager implements a 1Mbps receiver, including analog front-end and variable-gain amplifier at each pixel. Algorithms are ...

Brain atlases and associated databases have great potential as gateways for navigating, accessing, and visualizing a wide range of neuroscientific data. Recent progress towards realizing this potential includes the establishment of probabilistic atlases, surface-based atlases and associated databases, combined with improvements in visualization capabilities and internet access.

the aim of this study was to investigate the range utilization of rhode island red hens, grazing outdoor (under tropical conditions) and to scan their activities inside the house as well as during their outdoor visits. the activities of rir hens, raised in indoor floor pens connected with outdoor areas covered with natural vegetation, were scanned and recorded individually within 15 minute inte...

The Red Sea (Lessepsian) migrant fish, the arrow bulleye, Priacanthus sagittarius, and the spotbelly batfish, Platax teira, are recorded for the second time from the Mediterranean, suggesting the establishment of new populations. The record of another Lessepsian migrant, the spiny blaassop, Tylerius spinosissimus from Israel, constitutes a considerable extension of its distribution range in the...

Mitotic spindle position is controlled by interactions of cortical molecular motors with astral microtubules. In animal cells, Partner of Inscuteable (Pins) acts at the cortex to coordinate the activity of Dynein and Kinesin-73 (Khc73; KIF13B in mammals) to orient the spindle. Though the two motors move in opposite directions, their synergistic activity is required for robust Pins-mediated spin...

Tree fern trunks provide establishment surfaces and habitat for a range of plant taxa including many understorey shrubs canopy trees. The importance these habitats augmenting forest biodiversity woody regeneration processes has been the subject conjecture but not robustly assessed.

Recent experiments have revealed that some membrane proteins aggregate to form clusters. This type of process has been proven to be dynamic and to be actively maintained by external kinetics. Additionally, this dynamic recruiting is cholesterol- and actin-dependent, suggesting that raft organization and cytoskeleton rearrangement play a crucial role. In the present study, we propose a simple mo...
