Traditionally astrophysics has concerned itself with minimum time-scales measured
in hours rather than seconds. This was understandable as the available recording
media were slow; e.g. chart recorders and photographic plates. In the 1950s, 60s
and 70s wavebands away from the optical were developed; from ground based
radio studies to space and balloon borne high energy work. In contrast to optical
wavelengths instrumentation in these (high and low energy) regimes was capable
of time resolutions of less than a second....
This paper presents a supervised pronoun anaphora resolution system based on factorial hidden Markov models (FHMMs). The basic idea is that the hidden states of FHMMs are an explicit short-term memory with an antecedent buffer containing recently described referents. Thus an observed pronoun can ﬁnd its antecedent from the hidden buffer, or in terms of a generative model, the entries in the hidden buffer generate the corresponding pronouns.
Transmission electron microscopy (TEM) is a technique where the electron-beam is
transmitted through an ultra-thin specimen, interacting with specimen as it passes
through it. An image is formed from the interaction of the electrons transmitted
through the specimen, which is then magnified and focused onto an imaging device,
such as a fluorescent screen, a photographic film, or a charge-coupled device (CCD)
sensor. This technique is capable of imaging at significantly high resolution than the
light microscopes, owing to the small de-Broglie wavelength of electrons....
A survey conducted several years ago within the local atmospheric science
community had indicated the need for a comprehensive reference book of atmospheric
chemistry and physics. The present compilation of data has been prepared
in an attempt to fi ll this need.
While the subject, as a whole or in parts, has received an adequate treatment in
textbooks, encyclopedias, and in other overviews, these publications do not generally
present numerical data but discuss important observations by way of illustrations.
the beginning, medicinal therapy consisteodf concoctions coadministered
with incantations. Little thought was given to dissecting out the
contributions of the pharmacology of the concoction from the spiritual
consequences of the incantations. Eventually, potions and extracts were
recognized to have predictable activity that could be observed and described
objectively. Then came the capacity to estimate potency,t o l eading
concentration and purification.
I send you a gift, which if it answers ill the obligations I owe you, is at any rate the greatest which Niccolò
Machiavelli has it in his power to offer. For in it I have expressed whatever I have learned, or have observed
for myself during a long experience and constant study of human affairs. And since neither you nor any other
can expect more at my hands, you cannot complain if I have not given you more.
You may indeed lament the poverty of my wit, since what I have to say is but poorly said; and tax the
weakness of my judgment,...
Carbon nanotubes were identified for the first time in 1991 by Sumio Iijima at
the NEC Research Laboratory, using high resolution transmission electron microscopy,
while studying the soot made from by-products obtained during the
synthesis of fullerenes by the electric arc discharge method. In this soot, Iijima
clearly observed the so-called multiwalled nanotubes, molecular carbon tubes
with diameters in the nanometer range, consisting of carbon atoms arranged
in a seamless graphitic structure rolled up to form concentric cylinders.
In our quest to elucidate the origin of the universe and the formation of
galaxies, particularly that of the Milky Way in which we live, astounding
progress has been made in recent years through observational and theoretical
studies. Not only have gigantic surveys covering a large fraction of the sky
brought statistics enlightening evolutionary paths of galaxies, but powerful
instruments, such as radio interferometers and ground- and space-based optical/
infrared telescopes, have been able to map individual objects with high
sensitivity and spatial resolution.
Improvements in atmospheric observations, further understanding of atmospheric processes, and advances in technology will continue to enhance the accuracy and resolution of atmospheric analysis and prediction. As a consequence, society will enjoy greater confidence in atmospheric information and forecasts and will be able to act more decisively and effectively.
These limitations arise because the P2P world is lacking in the areas of semantics, data transformation, and data
relationships, yet these are some of the core strengths of the data management community. Queries, views, and
integrity constraints can be used to express relationships between existing objects and to deﬁne new objects in terms
of old ones. Complex queries can be posed across multiple sources, and the results of one query can be materialized
and used to answer other queries.
A key observation of the paper is that neither the branch nor the subsidiary structure is
obviously preferable in all cases from the financial stability perspective. The key to
ensuring financial stability lies instead in the design of effective mechanisms to oversee and
resolve cross-border banking groups. These include effective home/host supervision and
information-sharing arrangements and satisfactory cross-border resolution regimes and burden-
The solution structure of a recombinant mutant [rSP-C (FFI)] of the human surfactant-associatedprotein C
(hSP-C) in a mixture of chloroform andmethanol was
determined by high-resolution NMR spectroscopy. rSP-C (FFI) contains a helix from Phe5 to theC-terminal Leu34
andis thus longer by two residues than the helix of porcine
SP-C (pSP-C), which is reportedto start at Val7 in the same
solvent. Two sets of resonances at the C-terminus of the
peptide were observed, which are explained by low-order
oligomerization, probably dimerization of rSP-C (FFI) in
its a-helical form. ...
The structures of MornigaM and the MornigaM–mannose complex have
been determined at 1.8 A˚ and 2.0 A˚
resolution, respectively. Both struc-tures adopt the typical b-prism motif found in other jacalin-related lectins
and their tetrameric assembly closely resembles that of jacalin. The carbo-hydrate-binding cavity of MornigaM readily binds mannose. No major
structural rearrangements can be observed in MornigaM upon binding of
mannose. These results allow corroboration of the structure–function rela-tionships within the small group of Moraceae lectins....
