Ultrasound imaging is a safe and noninvasive window into the body’s workings, providing clinicians with live images of a patient’s internal organs. To capture these images, trained technicians manipul...

Branch diffusion process of single particle particle
2015/9/25
We investigate the long-time and long-range behavior of branching diffusion processes (starting with a single particle) in two different situations: when the
branching potential has compact support a...
Exotic, gigantic molecules fit inside each other like Russian nesting dolls
Exotic gigantic molecules fit inside each other like Russian nesting dolls
2015/3/4
University of Chicago scientists have experimentally observed for the first time a phenomenon in ultracold, three-atom molecules predicted by Russian theoretical physicist Vitaly Efimov in 1970.In thi...
We investigate the possibility of having horizons inside various classical field configurations. Using the implicit function theorem, we show that models satisfying a certian set of criteria allow for...
The Creation and Propagation of Radiation: Fields Inside and Outside of Sources
The Creation Propagation of Radiation Fields Inside Outside of Sources
2011/8/5
Abstract: We present a new algorithm for computing the electromagnetic fields of currents inside and outside of finite current sources, for arbitrary time variations in the currents. Unexpectedly, we ...
Measuring Colloidal Forces from Particle Position Deviations inside an Optical Trap
Measuring Colloidal Forces Particle Position Deviations
2010/11/17
We present a method to measure interaction forces between pairs of charged colloidal particles
suspended in a relatively low-polar medium (5 . " . 8) directly from the deviations of particle
positio...
Strain determination in the Si channel above a single SiGe island inside a field effect transistor using nanobeam x-ray diffraction
Strain determination Si channel field effect transistor
2010/11/24
SiGe islands are used to induce tensile strain in the Si channel of Field E ect Transistors to achieve larger transconductance and higher current driveabilities. We report on x-ray di raction experime...
Triply-resonant Optical Parametric Oscillator by Four-wave Mixing with Rubidium Vapor inside an Optical Cavity
Optical Parametric Oscillator Four-wave Mixing Optical Cavity
2010/3/10
We present an experimental demonstration of simultaneous above-threshold oscillations of the Stokes and anti-Stokes fields together with the single pumping beam with rubidium atoms inside an optical s...
Axial electric wake field inside the induction gap exited by the intense electron beam
linear induction accelerator induction gap wake field high voltage breakdown property
2009/8/17
While an intense electron beam passes through the accelerating gaps of a linear induction accelerator, a strong wake field will be excited. In this paper a relatively simple model is established based...
In some textbooks on quantum mechanics, the description of flux quantization in a superconductor ring based on the Aharonov-Bohm effect may lead some readers to a (wrong) conclusion that flux quantiza...
