The ground-s.ate property of a 2-dimens.onal 3-electron quantum dot (QD) s.bjected to an external magnetic fieldB and affected by an impurity is.s.udied. The impurity is.located at thez-axis.by a dis.anced from the plane of the dot. The evolution of the angular momentumL o and the s.ins.o of the ground s.ate in accordance withB andd has.been calculated, and the res.lts.are s.mmarized and plotted in a (L o,s.o) diagram. The s.atial dis.ribution of the electrons.(the s.ze and the geometric features. and the optical abs.rption have als. been inves.igated. The (L o s.o) diagram indicates.thatL o ands.o may jump whend and/orB vary. It was.found that, due to the cons.raints.aris.ng from s.mmetry, each s.mmetric geometry is.acces.ible only to a s.ecific group of s.ates.having s.ecificL o ands.o.

A new algorithm for retrieving wind vector us.ng dual polarization imagery of advanced s.nthetic aperture radar (As.R) is.developed and tes.ed. Bas.d on the combination of co-polarization and cros.-polarization, this.new algorithm effectively eliminates.the 1.0° ambiguity which occurs.when us.ng s.ngle imagery of the As.R to retrieve wind vector. This.algorithm als. s.lves.the problem that the retrieval res.lts.will break down on very s.all s.atial s.ales. The res.lts.retrieved from dual polarization imagery of As.R s.ow that the wind s.eed and direction are in agreement with the data from Quiks.at and buoy meas.rements. The root mean s.uare errors.of wind direction and s.eed between the retrieved res.lts.and data from Quiks.at are 2.21. and 0.53 m/s. res.ectively. Comparis.ns.between the new method and the traditional method s.ow that the new methods.fit the buoy data and Quiks.at data a little better than the traditional method in this.image.

Reproductive behaviors.are poorly known for the Yangtze finles. porpois. Neophocaena phocaenoides.as.aeorientalis. In this.s.udy, the parentage of an is.lated Yangtze finles. porpois. population inhabiting the Yangtze Tian-e-Zhou Baiji National Natural Res.rve is.determined by analys.s.of micros.tellite loci and mitochondrial DNA (mtDNA) control region s.quences. and the porpois.'s.reproductive behaviors.are s.udied. Overall 4 full parentage as.ignments.and additional 3 s.ngle parentage as.ignments.were determined for the population of 23 individuals. The analys.s.s.ows.that their es.imated reproductive cycle is.s.orter than that reported previous.y and there probably exis.s.an overlapping between ges.ation and lactation period. The s.udy als. s.ows.that the female does.not s.ow fidelity to a particular male for breeding and vice vers., the oldes. males.did not monopolize mating and the dominance rank could not be s. s.rict for the porpois. s.ciety. Moreover, the porpois.'s.mating pattern and relatednes. among candidate parents.are dis.us.ed here. Thes. res.lts.provide important information for making guidelines.of management and cons.rvation for this.protected population.
