Effects of Different Low Overwintering Temperatures on Angelica Vernalization and Premature Bolting

Angelica sinensis(Oliv.)Diels is a valuable herbal plant.In production,its premature bolting,caused by vernalization,seriously affects its root yield.In this stuty,thermal treatments of 5,0 and?5°C,as well as treatments with shifts between these temperatures,were performed in its overwintering storage to investigate the chilling effect on the early bolting of Angelica sinensis and analyze the vernalization response to different temperatures.The results indicated that the 0°C treatment rendered the highest bolting rate,and the-5°C resulted in the lowest bolting rate.The initial short-term treatment at-5°C could promote the early bolting of A.sinensis,and the treatment at 5°C prior to planting could hasten its seedling bud growth.At the appropriate temperature,the early bolting rate of Angelica was positively related to the number of treatment days.So the frozen storage at-5°C could inhibit the vernalization of Angelica seedlings and the early bolting.The vernalization of Angelica could be a continuous process related to the number of treatment days.This study would serve as reference for the overwintering storage and cultivation of Angelica.

Development of a Musical-based Interaction System for the Waseda Flutist Robot-Implementation of a Real-time Vision Interface Based on the Particle Filter Algorithm

The aim of this paper is to create an interface for humanrobot interaction. Specifically, musical performance parameters （i. e. vibrato expression） of the Waseda Flutist Robot No. 4 Refined IV （WF-4RIV） are to be manipulated. This research focused on enabling the WF-4RIV to interact with human players （musicians） in a natu- ral way. In this paper, as the first approach, a vision processing algorithm, which is able to track the 3Dorientation and position of a musical instrument, was developed. In particular, the robot acquires image data through two catneras attached to its head. Using color histogram matching and a particle filter, the position of the musician＇s hands on the inset are tracked. Analysis of this data determines orientation and location of the iustnment. These pa- rameters are mapped to manipulate the musical expression of the WF- 4RIV, more specifically sound vibrato and volume values. The authors present preliminary experiments to determine if the robot may dynamically change musical parameters while interacting with a human player （i.e. vibrato etc. ）. From the experirnental results, they may confirm the feasibility of the interaction during the performance, although further research must be carried out to consider the physical constraints of the flutist robot.

Detect early stage lung cancer by a LAMP microfluidic chip system with a real-time fluorescent filter processor

This work presents a promising clinical molecular diagnostics for early stage lung cancer. This novel diagnostic method utilized the loopmediated isothermal amplification （LAMP）, micro fluidic chips and a confocal optical detector with a nonlinear fluorescent filter processor. An isothermal amplification based microfluidic chip for the early diagnostics of lung cancer was developed and a confocal optical detector was improved by a novel real-time fluorescent filter to sensitively monitor the DNA amplification procedure with high signal to noise ratio and fluorescence collecting ability. Experiment showed that a rapid diagnostic of lung cancer by detecting the existence of the CEA mRNA could be performed in only 5 laL of reaction assay in less than 45 min. While the traditional intube RTPCR set consumed more than 25 -μL of the assay and took more than 90 rain.
