Background Cardiac arterial spin labeling (ASL) perfusion imaging requires subtraction of signals in tagged and control CMR images. In recent clinical studies, perfusion reserve mapping of a single short-axis slice has required laborious manual segmentation of the LV muscle [1]. Here we demonstrate that using free open source software for automatic motion correction reduces the required manual ...

In this paper a Bottom-Up (BU) method of obtaining information about pronunciation variation is proposed. BU transcriptions (Tbu) were obtained by letting a CSR decide for each phone whether it was deleted or not. The Tbu were compared to transcriptions obtained automatically with a TopDown method, and the agreement appeared to be very high. Subsequently, the Tbu were aligned with canonical ref...

Impact polypropylene (PP) copolymers (IPCs) are important materials for many commercial applications. These usually synthetized through different methods involving two consecutive reactions in the same phase or phases. Here, a laboratory-scale synthesis method based on sequential liquid- and gas-phase two-step process single reactor is developed. Propylene homopolymers IPCs were synthesized wit...

For the last several months the main focus of development in the ROOT I/O package has been code consolidation and performance improvements. We introduced a new pre-fetch mechanism to minimize the number of transactions between client and server, hence reducing the effect of latency on the time it takes to read a file both locally and over wide are network. We will review the implementation and ...

SiO2-supported silyl chromate catalyst is an important industrial catalyst for production of high grade HDPE pipe materials. The control of the short chain branch (SCB) distribution using this catalyst system is still a great challenge. In this work, ethylene and 1-hexene copolymers were synthesized using SiO2-supported silyl chromate catalyst combined with triisobutylaluminium (TIBA), triethyl...

Porous organic polymers (POPs) are widely used in various areas such as adsorption, separation and catalysis. In the present work, ionic liquid-modified porous (IL-POPs) synthesized by dispersion polymerization were applied to immobilize metallocene catalysts for olefin polymerization. The prepared IL-POPs characterized Fourier transform infrared spectrometer (FT-IR), nitrogen sorption porosime...
