text: Cross-metathesis reactions of α,β-unsaturated sulfones and sulfoxides in the
presence of molybdenum and ruthenium pre-catalysts were tested. A selective metahesis
reaction was achieved between functionalized terminal olefins and vinyl sulfones
by using the ‘second generation’ ruthenium catalysts 1c–h while the highly active
Schrock catalyst 1b was found to be functional group incompatible with vinyl sulfones.
The cross-metathesis products were isolated in good yields with an excellent (E)-selectivity.
Both the molybdenum and ruthenium-based complexes were, however, incompatible
with α,β- and β,γ-unsaturated sulfoxides.

text: 'Among the major mathematical approaches to mirror symmetry are those of Batyrev-Borisov
and Stromdnger-Yau-Zaslow (SYZ). The first is explicit and amenable to computation
but is not clearly related to the physical motivation; the second is the opposite.
Furthermore, it is far from obvious that mirror partners in one sense will also
be mirror partners in the other. This paper concerns a class of examples that
can be shown to satisfy the requirements of SYZ, but whose Hodge numbers are also
equal. This provides significant evidence in support of SYZ. Moreover, the examples
are of great interest in their own right: they are spaces of flat SLr-connections
on a smooth curve. The mirror is the corresponding space for the Langlands dual
group PGLr. These examples therefore throw a bridge from mirror symmetry to the
duality theory of Lie groups and, more broadly, to the geometric Langlands program.'

text: The moduli space of stable bundles of rank $2$ and degree $1$ on a Riemann
surface has rational cohomology generated by the so-called universal classes.
The work of Baranovsky, King-Newstead, Siebert-Tian and Zagier provided a complete
set of relations between these classes, expressed in terms of a recursion in the
genus. This paper accomplishes the same thing for the noncompact moduli spaces
of Higgs bundles, in the sense of Hitchin and Simpson. There are many more independent
relations than for stable bundles, but in a sense the answer is simpler, since
the formulas are completely explicit, not recursive. The results of Kirwan on
equivariant cohomology for holomorphic circle actions are of key importance.

text: 'We study the free expansion of a pancake-shaped Bose-condensed gas, which
is initially trapped under harmonic confinement and containing a vortex at its
centre. In the case of a radial expansion holding the axial confinement fixed
we consider various models for the interactions, depending on the thickness of
the condensate relative to the value of the scattering length. We are thus able
to evaluate different scattering regimes ranging from quasi-three-dimensional
(Q3D) to strictly two-dimensional (2D). We find that as the system goes from Q3D
to 2D the expansion rate of the condensate increases whereas that of the vortex
core decreases. In the Q3D scattering regime we also examine a fully free expansion
in 3D and find oscillatory behaviour for the vortex core radius: an initial fast
expansion of the vortex core is followed by a slowing down. Such a nonuniform
expansion rate of the vortex core implies that the timing of its observation should
be chosen appropriately.'

text: 'Social and solitary feeding in natural Caenorhabditis elegans isolates are
associated with two alleles of the orphan G-protein-coupled receptor (GPCR) NPR-1:
social feeders contain NPR-1 215F, whereas solitary feeders contain NPR-1 215V.
Here we identify FMRFamide-related neuropeptides (FaRPs) encoded by the flp-18
and flp-21 genes as NPR-1 ligands and show that these peptides can differentially
activate the NPR-1 215F and NPR-1 215V receptors. Multicopy overexpression of
flp-21 transformed wild social animals into solitary feeders. Conversely, a flp-21
deletion partially phenocopied the npr-1(null) phenotype, which is consistent
with NPR-1 activation by FLP-21 in vivo but also implicates other ligands for
NPR-1. Phylogenetic studies indicate that the dominant npr-1 215V allele likely
arose from an ancestral npr-1 215F gene in C. elegans. Our data suggest a model
in which solitary feeding evolved in an ancestral social strain of C. elegans
by a gain-of-function mutation that modified the response of NPR-1 to FLP-18 and
FLP-21 ligands.'

text: In many animal species individuals aggregate to live in groups. A range of
experimental approaches in different animals, including studies of social feeding
in nematodes, maternal behavior in rats and sheep, and pair-bonding in voles,
are providing insights into the neural bases for these behaviors. These studies
are delineating multiple neural circuits and gene networks in the brain that interact
in ways that are as yet poorly understood to coordinate social behavior.

text: Proteins of the ARGONAUTE family are important in diverse posttranscriptional
RNA-mediated gene-silencing systems as well as in transcriptional gene silencing
in Drosophila and fission yeast and in programmed DNA elimination in Tetrahymena.
We cloned ARGONAUTE4 (AGO4) from a screen for mutants that suppress silencing
of the Arabidopsis SUPERMAN(SUP) gene. The ago4-1 mutant reactivated silentSUP
alleles and decreased CpNpG and asymmetric DNA methylation as well as histone
H3 lysine-9 methylation. In addition,ago4-1 blocked histone and DNA methylation
and the accumulation of 25-nucleotide small interfering RNAs (siRNAs) that correspond
to the retroelement AtSN1. These results suggest that AGO4 and long siRNAs direct
chromatin modifications, including histone methylation and non-CpG DNA methylation.

text: RNA interference is a conserved process in which double-stranded RNA is processed
into 21–25 nucleotide siRNAs that trigger posttranscriptional gene silencing.
In addition, plants display a phenomenon termed RNA-directed DNA methylation (RdDM)
in which DNA with sequence identity to silenced RNA is de novo methylated at its
cytosine residues. This methylation is not only at canonical CpG sites but also
at cytosines in CpNpG and asymmetric sequence contexts. In this report, we study
the role of the DRM and CMT3 DNA methyltransferase genes in the initiation and
maintenance of RdDM. Neither drm nor cmt3 mutants affected the maintenance of
preestablished RNA-directed CpG methylation. However, drm mutants showed a nearly
complete loss of asymmetric methylation and a partial loss of CpNpG methylation.
The remaining asymmetric and CpNpG methylation was dependent on the activity of
CMT3, showing that DRM and CMT3 act redundantly to maintain non-CpG methylation.
These DNA methyltransferases appear to act downstream of siRNAs, since drm1 drm2
cmt3 triple mutants show a lack of non-CpG methylation but elevated levels of
siRNAs. Finally, we demonstrate that DRM activity is required for the initial
establishment of RdDM in all sequence contexts including CpG, CpNpG, and asymmetric
sites.

text: In metazoa, the nuclear envelope breaks down and reforms during each cell
cycle. Nuclear pore complexes (NPCs), which serve as channels for transport between
the nucleus and cytoplasm1, assemble into the reforming nuclear envelope in a
sequential process involving association of a subset of NPC proteins, nucleoporins,
with chromatin followed by the formation of a closed nuclear envelope fenestrated
by NPCs2,3,4,5,6,7. How chromatin recruitment of nucleoporins and NPC assembly
are regulated is unknown. Here we demonstrate that RanGTP production is required
to dissociate nucleoporins Nup107, Nup153 and Nup358 from Importin β, to target
them to chromatin and to induce association between separate NPC subcomplexes.
Additionally, either an excess of RanGTP or removal of Importin β induces formation
of NPC-containing membrane structures—annulate lamellae—both in vitro in the absence
of chromatin and in vivo. Annulate lamellae formation is strongly and specifically
inhibited by an excess of Importin β. The data demonstrate that RanGTP triggers
distinct steps of NPC assembly, and suggest a mechanism for the spatial restriction
of NPC assembly to the surface of chromatin.

text: Nuclear pore complexes (NPCs) are large multiprotein assemblies that allow
traffic between the cytoplasm and the nucleus. During mitosis in higher eukaryotes,
the Nuclear Envelope (NE) breaks down and NPCs disassemble. How NPCs reassemble
and incorporate into the NE upon mitotic exit is poorly understood. We demonstrate
a function for the conserved Nup107-160 complex in this process. Partial in vivo
depletion of Nup133 or Nup107 via RNAi in HeLa cells resulted in reduced levels
of multiple nucleoporins and decreased NPC density in the NE. Immunodepletion
of the entire Nup107-160 complex from in vitro nuclear assembly reactions produced
nuclei with a continuous NE but no NPCs. This phenotype was reversible only if
Nup107-160 complex was readded before closed NE formation. Depletion also prevented
association of FG-repeat nucleoporins with chromatin. We propose a stepwise model
in which postmitotic NPC assembly initiates on chromatin via early recruitment
of the Nup107-160 complex.

text: In this paper we consider the online ftp problem. The goal is to service a
sequence of file transfer requests given bandwidth constraints of the underlying
communication network. The main result of the paper is a technique that leads
to algorithms that optimize several natural metrics, such as max-stretch, total
flow time, max flow time, and total completion time. In particular, we show how
to achieve optimum total flow time and optimum max-stretch if we increase the
capacity of the underlying network by a logarithmic factor. We show that the resource
augmentation is necessary by proving polynomial lower bounds on the max-stretch
and total flow time for the case where online and offline algorithms are using
same-capacity edges. Moreover, we also give polylogarithmic lower bounds on the
resource augmentation factor necessary in order to keep the total flow time and
max-stretch within a constant factor of optimum.

and meshes. We study both the offline and the online version of the problem: In
the offline setting, we give the first constant-factor approximation algorithm
for trees, and an -factor approximation algorithm for meshes. In the online setting,
we give the first polylogarithmic competitive online algorithm for tree and mesh
topologies. No polylogarithmic-competitive algorithm is possible on general network
topologies (Lower bounds for on-line graph problems with application to on-line
circuits and optical routing, in: Proceedings of the 28th ACM Symposium on Theory
of Computing, 1996, pp. 531–540) and there exists a polylogarithmic lower bound
on the competitive ratio of any online algorithm on tree topologies (Making commitments
in the face of uncertainity: how to pick a winner almost every time, in: Proceedings
of the 28th Annual ACM Symposium on Theory of Computing, 1996, pp. 519–530). We
prove the same lower bound for meshes.'

text: Many daily activities present information in the form of a stream of text,
and often people can benefit from additional information on the topic discussed.
TV broadcast news can be treated as one such stream of text; in this paper we
discuss finding news articles on the web that are relevant to news currently being
broadcast.We evaluated a variety of algorithms for this problem, looking at the
impact of inverse document frequency, stemming, compounds, history, and query
length on the relevance and coverage of news articles returned in real time during
a broadcast. We also evaluated several postprocessing techniques for improving
the precision, including reranking using additional terms, reranking by document
similarity, and filtering on document similarity. For the best algorithm, 84%-91%
of the articles found were relevant, with at least 64% of the articles being on
the exact topic of the broadcast. In addition, a relevant article was found for
at least 70% of the topics.

text: "This paper addresses the problem of topic distillation on the World Wide
Web, namely, given a typical user query to find quality documents related to the
query topic. Connectivity analysis has been shown to be useful in identifying
high quality pages within a topic specific graph of hyperlinked documents. The
essence of our approach is to augment a previous connectivity analysis based algorithm
with content analysis. We identify three problems with the existing approach and
devise algorithms to tackle them. The results of a user evaluation are reported
that show an improvement of precision at 10\r\ndocuments by at least 45% over
pure connectivity analysis. "

text: We investigate the ground state properties of a gas of interacting particles
confined in an external potential in three dimensions and subject to rotation
around an axis of symmetry. We consider the Gross-Pitaevskii (GP) limit of a dilute
gas. Analysing both the absolute and the bosonic ground states of the system,
we show, in particular, their different behaviour for a certain range of parameters.
This parameter range is determined by the question whether the rotational symmetry
in the minimizer of the GP functional is broken or not. For the absolute ground
state, we prove that in the GP limit a modified GP functional depending on density
matrices correctly describes the energy and reduced density matrices, independent
of symmetry breaking. For the bosonic ground state this holds true if and only
if the symmetry is unbroken.
