Multimode single-pass spatio-temporal squeezing

Spatio-temporal signature of a multimode optical fibre

Both phase and group velocities of all guided modes of a moderately multimode fibre are experimentally determined from a single sample. Modes are excited by a picosecond optical pulse and spatially separated at the etched fibre end. A picosecond streak camera records their spatial and temporal output coordinates.

Probing multimode squeezing with correlation functions

Broadband multimode squeezers constitute a powerful quantum resource with promising potential for different applications in quantum information technologies such as information coding in quantum communication networks or quantum simulations in higher-dimensional systems. However, the characterization of a large array of squeezers that coexist in a single spatial mode is challenging. In this pap...

Spatio-Temporal Modeling of First-Pass Perfusion Cardiovascular MRI

INTRODUCTION First-pass contrast enhanced myocardial perfusion Magnetic Resonance Imaging (MRI) is a promising technique for providing insight into how reduced coronary flow affects the myocardial tissue. It also allows the understanding of microcirculation in the myocardial tissue and myocardial angiogenesis [1]. Clinically, myocardial perfusion MRI plays a major role in the evaluation of isch...

A 2-Pass Data Mining Technique for Spatio-Temporal Datasets

Modeling of spatio-temporal of albedo over Iran

The aim of this study is modeling spatiotemporal variations of albedo. This study was conducted using simultaneous effects of several components, such as wetness of surface layer of soil, cloudiness, topography and vegetation density (NDVI), using MEERA2 model with a resolution of 50 in 50 km during 2000-2010 in Iran. The results of spatial analysis of albedo values in Iran showed that the high...
