The mechanisms by which the diverse functional identities of neurons are generated are poorly understood. C. elegans responds to thermal and chemical stimuli using 12 types of sensory neurons. The Otx/otd homolog ttx-1 specifies the identities of the AFD thermosensory neurons. We show here that ceh-36 and ceh-37, the remaining two Otx-like genes in the C. elegans genome, specify the identities ...

Chemosensory neurons extract information about chemical cues from the environment. How is the activity in these sensory neurons transformed into behavior? Using Caenorhabditis elegans, we map a novel sensory neuron circuit motif that encodes odor concentration. Primary neurons, AWC(ON) and AWA, directly detect the food odor benzaldehyde (BZ) and release insulin-like peptides and acetylcholine, ...

This article presents a description and performance evaluation of an efficient distributed dynamic channels allocation (DDCA) scheme, which can be used for channel allocation in cellular communication networks (CCNs), such as the global system for mobile communication (GSM). The scheme utilizes a well-known distributed artificial intelligence (DAI) algorithm, namely, the asynchronous weak-commi...

To study the molecular basis for predator-prey coevolution, we investigated how Caenorhabditis elegans responds to the predatory fungus Arthrobotrys oligospora. C. elegans and other nematodes were attracted to volatile compounds produced by A. oligospora. Gas-chromatographic mass-spectral analyses of A. oligospora-derived volatile metabolites identified several odors mimicking food cues attract...

Automatic recognition of fruits and vegetable products via computer vision is still a difficult task due to complexity of environment. This paper develops a robust fruit and vegetable products recognition method, which integrates color and texture feature based on Harmonic adaptive feature fusion (HAFF) algorithm proposed by this paper. HAFF firstly use exp function to improve AWC, then compute...
