Ultracold atoms are still too hot. This may seem a ridiculous claim—after
all, the low-temperature exploits of the purveyors of quantum gases are
notorious. Laser cooling can flash-freeze atoms to temperatures in the micro-
and nanokelvin...

This investigation's objective is to obtain spectroscopic observations of
potential comet-asteroid transition objects and extinct comet candidates using
ground-based telescopes to attain the following goals:
1) Identify potential...

Abstract :
Resolving individual atoms has always been the ultimate goal of
surface microscopy. The scanning tunneling microscope images
atomic-scale features on surfaces, but resolving single atoms...

Abstract
Central to the study of stratospheric ozone recovery and climate change, is
the ability to predict emissions of Montreal Protocol-restricted halocarbons (MPGs)
over the coming decades. The prediction of emissions has become...

In the 2,000 or so years since the Roman Empire employed a naturally
occurring form of cement to build a vast system of concrete aqueducts and other
large edifices, researchers have analyzed the molecular structure of natural
materials and...

Molecular systems, or systems based on small organic molecules, possess
interesting and useful electronic properties. The rapidly developing area of
organic -or plastic- electronics is based on these materials. The investigations

The combustion of biomass is a major source of atmospheric trace gases and
aerosols. Regional- and global-scale models of atmospheric chemistry and climate
take estimates for these emissions and arbitrarily "mix" them into grid boxes...

Control of polymer morphology and chain orientation is of great importance in
organic solar cells and field effect transistors (OFETs). Here we report the use
of nanoimprint lithography to fabricate large-area, high-density, and ordered...

Much of our knowledge about molecular structure and reactivity is based on
interpreting how molecules interact with light. In particular, time-resolved
pump-probe studies where a first “pump” laser pulse initiates a dynamical
event,...

This Research
introduces a DC motor drive system with a fuzzy-artificial neural-network
controller. First, a neural network-based architecture is described for fuzzy
logic control. The characteristic rules and their membership functions of...

In this paper, researchers deal with the observability and observer design of
a certain class of reactors (batch reactors) which are globally asymptotically
feedback stabilisable. They show how to design two types of high-gain observers:

Einstein introduced general relativity in the early 20th century, and since
then it has been proven to be an accurate description of gravity beyond the
regime of validity of Newtonian gravitation. Since then, people have been
