In this paper, we present Espresso, a weakly-supervised iterative algorithm combined with a web-based knowledge expansion technique, for extracting binary semantic relations. Given a small set of seed instances for a particular relation, the system learns lexical patterns, applies them to extract new instances, and then uses the Web to filter and expand the instances. Preliminary experiments sh...

The redesigned Extensible Simulation Package for Research on Soft matter systems (ESPResSo++) is a free, open-source, parallelized, object-oriented simulation package designed to perform many-particle simulations, principally molecular dynamics and Monte Carlo, of condensed soft matter systems. In addition to the standard simulation methods found in well-established packages, ESPResSo++ provide...

ترکیبات mgcni3و incni3 ابررسانا هایی هستند که ساختار ی شبیه به ساختار ساده ترکیبات پروسکیت مکعبی دارند، و به ترکیبات پادپروسکیت معروفند. البته علاقهمندی به تحقیق در رابطه با ترکیباتی از این قبیل تنها به خاطر ابررسانایی دمای پایین آن نیست. بلکه بیشتر به خاطر ساختار ساده پروسکیتی بدون اکسیژن آن می باشد، که می تواند با چنین ساختاری یک ابررسانا باشد. در این پایان نامه با دو بسته محاسباتی wien2k و...

In this paper, we present Espresso, a weakly-supervised, general-purpose, and accurate algorithm for harvesting semantic relations. The main contributions are: i) a method for exploiting generic patterns by filtering incorrect instances using the Web; and ii) a principled measure of pattern and instance reliability enabling the filtering algorithm. We present an empirical comparison of Espresso...

Methylxanthines present psychostimulant effects. These compounds have low toxicity and their consumption at moderate levels presents some beneficial health effects, whereas some significant risk appears at high levels. Samples of common types of methylxanthine-containing beverages and foods consumed in Spain were analyzed to determine their content. Caffeine was the methylxanthine that was most...

QUANTUM ESPRESSO is an integrated suite of computer codes for electronic-structure calculations and materials modeling, based on density-functional theory, plane waves, and pseudopotentials (norm-conserving, ultrasoft, and projector-augmented wave). The acronym ESPRESSO stands for opEn Source Package for Research in Electronic Structure, Simulation, and Optimization. It is freely available to r...

In this extended abstract, we summarize our study on implementing tautology checking, a fundamental logic synthesis algorithm, using an FPGA-based reconfgurable applicationspecific coprocessor. The use of the tautology checking algorithm is first discussed followed by the specifics of hardware accelerator implementation and intetiace to application sofrware. We compare our hardware accelerator ...

Two regular circuit structures based on the programmable logic array (PLA) are proposed. They provide alternatives to the widely used standard-cell structure and have better predictability and simpler design methodologies. A whirlpool PLA is a cyclic four-level structure, which has a compact layout. Doppio-ESPRESSO, a four-level logic minimization algorithm, is developed for the synthesis of Wh...

Context. ESPRESSO is the new high-resolution spectrograph of ESO’s Very Large Telescope (VLT). It was designed for ultra-high radial-velocity (RV) precision and extreme spectral fidelity with aim performing exoplanet research fundamental astrophysical experiments unprecedented accuracy. able to observe any four Unit Telescopes (UTs) VLT at a resolving power 140 000 or 190 over 378.2 788.7 nm wa...
