The CMDASH’07 team follows our past teams CMDash’06, CMDash’05, CMPack’04, CMPack’03, CMPack’02, CMPack’01, CMPack’00, CMTrio’99, and CMTrio’98 [5, 3, 7, 6]. We have continued our research into new ways of modeling the world and maintained our focus on robust behaviors and cooperation. In this paper, we provide an overview of the specific technical components in our team and focus in detail on ...

Bose-Einstein condensates have been prepared in long-lived metastable excited states. Two complementary types of metastable states were observed. The first is due to the immiscibility of multiple components in the condensate, and the second to local suppression of spin-relaxation collisions. Relaxation via recondensation of noncondensed atoms, spin relaxation, and quantum tunneling was observed...
to extract active components from the traditional Chinese medicine Polygonum cuspidatum using a trans-resveratrol imprinted polymer. Good separation and purification of trans-resveratrol and emodin from the Polygonum cuspidatum extract are achieved after condition optimization. The extraction recoveries are 83% and 99% for trans-resveratol and emodin, respectively. The results show that the mol...
We report the results of P NMR measurements on trioctylphosphine oxide ~TOPO! passivated InP quantum dots. The spectra show distinct surface-capping sites, implying a manifold of crystal– ligand bonding configurations. Two In P surface components are resolved and related to different electronic surroundings. With decreasing particle size the In P core resonance reveals an increasing upfield che...
We studied a Mediterranean species (Erica arborea L.) growing in a CO(2) spring in Italy that was naturally exposed for generations to a gradient of atmospheric CO(2) concentrations. The CO(2) concentration gradient to which different individual plants were exposed was determined by an indirect method based on radioisotope analysis. The stable carbon isotope ratio of sampled leaves was determin...
Many lakes have experienced a transition from a clear into a turbid state without macrophyte growth due to eutrophication. There are several measures by which nitrogen (N) and phosphorus (P) concentrations in the surface water can be reduced. We used the shallow lake model PCLake to evaluate the effects of three measures (reducing external nutrient loading, increasing relative marsh area, and i...
Blocking the natural bi-directional flow in an estuarine system using an artificial dyke has commonly caused serious water quality problems. In the southwestern part of South Korea, a parallel triple-reservoir system was constructed by blocking the mouth of three different rivers (Yeongsan, Okcheon, and Kumja), which were then interconnected using two open channels. This system has experienced ...
Total nitrogen (TN) and total phosphorus (TP) concentrations are important parameters to assess the quality of water bodies and are used as criteria to regulate the water quality of the effluent from a wastewater treatment plant (WWTP) in Korea. Therefore, continuous monitoring of TN and TP using in situ instruments is conducted nationwide in Korea. However, most in situ instruments in the mark...
Volumetric images of small mortar cylinders under load are acquired by X-ray microtomography. The images are binarized at different threshold values, and the connected components are extracted at each threshold with a 3D spaceand time-efficient program. Statistics of volume and surface area of separated concrete segments and cracks are collected and analyzed. Under increasing load, the concrete...
