BACKGROUND Animal behavior is governed by the activity of interconnected brain circuits. Comprehensive brain wiring maps are thus needed in order to formulate hypotheses about information flow and also to guide genetic manipulations aimed at understanding how genes and circuits orchestrate complex behaviors. RESULTS To assemble this map, we deconstructed… (More)
An incremental learning by navigation approach to vision based autonomous land vehicle (ALV) guidance in indoor environments is proposed. The approach consists of three stages: initial learning, navigation, and model updating. In the initial learning stage, the ALV is driven manually, and environment images and other status data are recorded automatically.… (More)
We study the cutoff phenomenon for generalized riffle shuffles where, at each step, the deck of cards is cut into a random number of packs of multinomial sizes which are then riffled together.
From the Surface Velocity Program (SVP) drifter current data, a detailed and complete track of strong ocean currents in the northwestern Pacific is provided using the bin average method. The focus of this study is on the Kuroshio, the strong western boundary current of the North Pacific flowing northward along the east coast of Taiwan and then turning… (More)
This paper considers word position information for language modeling. For organized documents, such as technical papers or news reports, the composition and the word usage of articles of the same style are usually similar. Therefore, the documents can be separated into partitions consisting of identical rhetoric or topic styles by the literary structures,… (More)
General and singular subcellular events within the ligand-dependent receptor-mediated cellular response were separated by using the Jurs and the electrotopological state (ES) descriptors, allowing characterization of the significant structural modifications in a given set of collected peroxisome proliferator-activated receptor γ (PPARγ) agonists. The… (More)
We consider the spectrum of birth and death chains on a n-path. An iterative scheme is proposed to compute any eigenvalue with exponential convergence rate independent of n. This allows one to determine the whole spectrum in order n 2 elementary operations. Using the same idea, we also provide a lower bound on the spectral gap, which is of the correct order… (More)
The segmentation of Drosophila mushroom bodies is highly demanded in the Dro-sophila brain research. In this work, we developed a template-based segmentation system with integration of the 3D average brain model. 3D registration and warping are performed to obtain the initial contours of the snake algorithm for the segmentation procedure. 3D models can be… (More)
