Maximizing the Impact of CSR in China [PDF]

, 2006
The past five years have seen a growing number of Corporate Social Responsibility (CSR) conferences in China, increasing participation by Chinese businesses in international multi-stakeholder processes, and the development of China-specific CSR standards.

Minimal dark matter in type III seesaw

, 2009
We explore the possibility of a new dark matter candidate in the supersymmetric type III seesaw mechanism where a neutral scalar component of the Y=0 triplet can be the lightest supersymmetric particle.

Predicting caustic crossing high magnification events in Q2237+0305

, 2000
The central regions of the gravitationally lensed quasar Q2237+0305 can be indirectly resolved on nano-arcsecond scales if viewed spectrophotometricly during a microlensing high magnification event (HME).

Remote Sensing using Signals of Opportunity

, 2013
Today, there are more than eight thousand satellites in space. Therefore, Radio Frequency (RF) signals broadcast from satellites can be accessed from almost every point on the earth. There will be number of satellites available at most points on earth with different frequency bands.

A Differential Positioning System Using Modulation Correlation of Signals of Opportunity [PDF]

, 2010
Global Navigation Satellite Systems (GNSS) have become the positioning systems of choice for many applications. However, GNSS signals are susceptible to obstruction, interference and jamming.

Feasibility Study on Passive-radar Detection of Space Targets Using Spaceborne Illuminators of Opportunity

Leida xuebao, 2015
Space target surveillance generally uses active radars. To take full advantage of passive radars, the idea of using spaceborne illuminators of opportunity for space target detection is presented in this paper.

Non-diagonal flavour observables in B and Collider Physics

, 2003
Until now the focus within the direct search for supersymmetry has mainly been on flavour diagonal observables. Recently lepton flavour violating signals at future electron positron colliders have been studied.

Joint pseudo-range and Doppler positioning method with LEO Satellites‘ signals of opportunity

Satellite Navigation
Low Earth Orbit (LEO) satellites, with their wide coverage and large number, have gradually become a crucial platform and means for navigation and positioning services. Compared to other LEO constellations, Starlink has over 6000 satellites in orbit, and
