i Summary Active vision systems have mechanisms that can actively control camera parameters such as position, orientation, focus, zoom, aperture and vergence (in a two camera system) in response to the requirements of the task and external stimuli. They may also have features such as spatially variant (foveal) sensors. More broadly, active vision encompasses attention, selective sensing in spac...

An important but poorly understood aspect of sensory processing is the role of active sensing, the use of self-motion such as eye or head movements to focus sensing resources on the most rewarding or informative aspects of the sensory environment. Here, we present behavioral data from a visual search experiment, as well as a Bayesian model of within-trial dynamics of sensory processing and eye ...

The purpose of the present Perspectives is to present a synopsis of the literature on bacterial "quorum sensing" as a background for the proposal that interference with this communication system offers potential targets for the design of novel antibiotic drugs. Quorum sensing is the recently discovered chemical communication system among bacteria (both Gram-positive and -negative). It is vital ...

An increasing number of systems and applications depend on photonics for transmission and signal processing. This includes data centers, communications systems, environmental sensing, radar, lidar, and microwave signal generation. Such systems increasingly rely on monolithic integration of traditionally bulk optical components onto the chip scale to significantly reduce power and cost while sim...

Microbes are omnipresent in nature with different forms of shape, size, colony morphology and substrate interaction modes. Microbial biofilm is a unique assemblage of microbes on the surface of the substrate. Recently it has fascinated the scientific community owing to its special properties which makes it notorious as well as a worthy living system. The establishment of the biofilm ecosystem i...

Mobility-on-demand (MoD) systems have recently emerged as a promising paradigm of one-way vehicle sharing for sustainable personal urban mobility in densely populated cities. In this paper, we enhance the capability of a MoD system by deploying robotic shared vehicles that can autonomously cruise the streets to be hailed by users. A key challenge to managing the MoD system effectively is that o...
