The effects of 4-aminopyridine (4-AP), a specific blocker of outward K(+) current, on voltage-activated transient outward K(+) current (I(K(A))) and inward Na(+) current (I(Na)) were investigated on cultured rat cerebellar granule cells using the whole cell voltage-clamp technique. At the concentration of 1-5 mM, 4-AP inhibited both I(K(A)) and I(Na). It(More)
Whether, when, and how do small firms innovate with IT? To address this question, we apply the concept of mindful innovation to a case study of a small independent restaurant that adopted, implemented, and used OpenTable, an online reservation system. Combining first-hand experience, interviews, and observation, we present a live adventure this restaurant(More)
Swelling-activated Cl- currents, I(Cl,swell) were measured during hyposmotic shock in white Leghorn embryonic chick heart cells using the whole-cell recording of patch-clamp technique. Genistein, an inhibitor of protein tyrosine kinase (PTK), suppressed I(Cl,swell). Under isosmotic condition phorbol 12-myristate 13-acetate (PMA), an activator of PKC,(More)
This project is part of the larger NSF-supported grant on Science and Technology Innovation Concept Knowledge-base (STICK). Previous research in trends of information technology innovations have found helpful patterns by studying the frequency of mention of key terms in trade and scholarly articles in bibliographic databases. The current efforts on this(More)
Nitrogen is an essential nutrient element in crop photosynthesis and yield improvement. Thus, it is urgent and important to accurately estimate the leaf nitrogen contents (LNC) of crops for precision nitrogen management. Based on the correlation between LNC and reflectance spectra, the hyperspectral LiDAR (HSL) system can determine three-dimensional(More)
The abilities of multispectral LiDAR (MSL) as a new high-potential active instrument for remote sensing have not been fully revealed. This study demonstrates the potential of using the spectral and spatial features derived from a novel MSL to discriminate surface objects. Data acquired with the MSL include distance information and the intensities of four(More)
