text: "We are given a set T = {T 1 ,T 2 , . . .,T k } of rooted binary trees, each
T i leaf-labeled by a subset L(Ti)⊂{1,2,...,n} . If T is a tree on {1,2, . . .,n
}, we let T|L denote the minimal subtree of T induced by the nodes of L and all
their ancestors. The consensus tree problem asks whether there exists a tree T
* such that, for every i , T∗|L(Ti) is homeomorphic to T i .\r\n\r\nWe present
algorithms which test if a given set of trees has a consensus tree and if so,
construct one. The deterministic algorithm takes time min{O(N n 1/2 ), O(N+ n
2 log n )}, where N=∑i|Ti| , and uses linear space. The randomized algorithm takes
time O(N log3 n) and uses linear space. The previous best for this problem was
a 1981 O(Nn) algorithm by Aho et al. Our faster deterministic algorithm uses a
new efficient algorithm for the following interesting dynamic graph problem: Given
a graph G with n nodes and m edges and a sequence of b batches of one or more
edge deletions, then, after each batch, either find a new component that has just
been created or determine that there is no such component. For this problem, we
have a simple algorithm with running time O(n 2 log n + b 0 min{n 2 , m log n
}), where b 0 is the number of batches which do not result in a new component.
For our particular application, b0≤1 . If all edges are deleted, then the best
previously known deterministic algorithm requires time O(mn−−√) to solve this
problem. We also present two applications of these consensus tree algorithms which
solve other problems in computational evolutionary biology."

text: "When using traditional search engines, users have to formulate queries to
describe their information need. This paper discusses a different approach to
Web searching where the input to the search process is not a set of query terms,
but instead is the URL of a page, and the output is a set of related Web pages.
A related Web page is one that addresses the same topic as the original page.
For example, www.washingtonpost.com is a page related to www.nytimes.com, since
both are online newspapers.\r\n\r\nWe describe two algorithms to identify related
Web pages. These algorithms use only the connectivity information in the Web (i.e.,
the links between pages) and not the content of pages or usage information. We
have implemented both algorithms and measured their runtime performance. To evaluate
the effectiveness of our algorithms, we performed a user study comparing our algorithms
with Netscape's `What's Related' service (http://home.netscape.com/escapes/related/).
Our study showed that the precision at 10 for our two algorithms are 73% better
and 51% better than that of Netscape, despite the fact that Netscape uses both
content and usage pattern information in addition to connectivity information."

text: Recent research has studied how to measure the size of a search engine, in
terms of the number of pages indexed. In this paper, we consider a different measure
for search engines, namely the quality of the pages in a search engine index.
We provide a simple, effective algorithm for approximating the quality of an index
by performing a random walk on the Web, and we use this methodology to compare
the index quality of several major search engines.

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.

text: "This paper solves a longstanding open problem in fully dynamic algorithms:
We present the first fully dynamic algorithms that maintain connectivity, bipartiteness,
and approximate minimum spanning trees in polylogarithmic time per edge insertion
or deletion. The algorithms are designed using a new dynamic technique that combines
a novel graph decomposition with randomization. They are Las-Vegas type randomized
algorithms which use simple data structures and have a small constant factor.\r\nLet
n denote the number of nodes in the graph. For a sequence of Ω(m0) operations,
where m0 is the number of edges in the initial graph, the expected time for p
updates is O(p log3 n) (througout the paper the logarithms are based 2) for connectivity
and bipartiteness. The worst-case time for one query is O(log n/log log n). For
the k-edge witness problem (“Does the removal of k given edges disconnect the
graph?”) the expected time for p updates is O(p log3 n) and the expected time
for q queries is O(qk log3 n). Given a graph with k different weights, the minimum
spanning tree can be maintained during a sequence of p updates in expected time
O(pk log3 n). This implies an algorithm to maintain a 1 + ε-approximation of the
minimum spanning tree in expected time O((p log3 n logU)/ε) for p updates, where
the weights of the edges are between 1 and U."

text: In this paper we present an analysis of an AltaVista Search Engine query log
consisting of approximately 1 billion entries for search requests over a period
of six weeks. This represents almost 285 million user sessions, each an attempt
to fill a single information need. We present an analysis of individual queries,
query duplication, and query sessions. We also present results of a correlation
analysis of the log entries, studying the interaction of terms within queries.
Our data supports the conjecture that web users differ significantly from the
user assumed in the standard information retrieval literature. Specifically, we
show that web users type in short queries, mostly look at the first 10 results
only, and seldom modify the query. This suggests that traditional information
retrieval techniques may not work well for answering web search requests. The
correlation analysis showed that the most highly correlated items are constituents
of phrases. This result indicates it may be useful for search engines to consider
search terms as parts of phrases even if the user did not explicitly specify them
as such.

a generalization of the edge-disjoint paths problem and is NPhard both on trees
and meshes. We study both the offline and the online version of the problem: In
the offline setting, we give the first\r\nconstant-factor approximation algorithm
for trees, and an O((log log n)*)-factor approximation algorithm for meshes, where
n is the number of nodes in the graph. In the online setting, we give the first
polylogarithrnic competitive online algorithm for tree and mesh topologies. No
polylogarithmic-competitive algorithm is possible on general network topologies
[8] and there\r\nexists a polylogarithmic lower bound on the competitive ratio
of any online algorithm on tree topologies [l]. We prove the same lower bound
for meshes. "

text: We study the long time evolution of a quantum particle in a Gaussian random
environment. We show that in the weak coupling limit the Wigner distribution of
the wave function converges to the solution of a linear Boltzmann equation globally
in time. The Boltzmann collision kernel is given by the Born approximation of
the quantum scattering cross section.

text: We give the leading order semiclassical asymptotics for the sum of the negative
eigenvalues of the Pauli operator (in dimension two and three) with a strong non-homogeneous
magnetic field. This result can be used to prove that the magnetic Thomas-Fermi
theory gives the leading order ground state energy of large atoms. We develop
a new localization scheme well suited to the anisotropic character of the strong
magnetic field. We also use the basic Lieb-Thirring estimate obtained earlier
(1996). (orig.) 19 refs.

text: Pattern formation in a layer of fluid heated from below is an example of macroscopic
ordering in continuous media. Here we show that in a relatively compact experimental
version of the problem, a rich and diverse set of stable flows can be found. These
flows, many of which are novel, can be categorized and understood in terms of
their symmetry properties. This approach shows promise for providing insight into
the more complicated fluid motion that occurs as the lateral dimension of the
layer is increased.

text: Using an electrospray tandem mass spectrometer as a concentration-sensitive
detector, a method has been developed to quantify femtomole amounts of plant growth
regulators (i.e. isoprenoid type cytokinins, zeatin, dihydrozeatin, isopentenyladenine
and their respective riboside and glucoside analogues) and the second messenger
adenosine 3':5'-cyclic monophosphate (3':5'-cAMP). Miniaturisation of the chromatographic
setup using capillary high performance liquid chromatographic (HPLC) ion spray
mass spectrometry increased the sensitivity to the low femtomole region. Application
of automated capillary column switching allowed the introduction of large injection
volumes into the HPLC system. Aliquots (25 μL) were injected into one dimension
of the HPLC set-up and stacked onto a micro pre-column. By means of mobile phase
switching the pre-column was back-flushed to introduce the analytes onto the analytical
column. For cytokinin analysis positive electrospray ionisation was used and resulted
in 2.5-25 fmol detection limits. Cyclic nucleotides were separated under ion-pair
conditions using tetrabutyl ammonium bromide as ion-pair reagent and were detected
under negative electrospray ionisation conditions. Here a 25 fmol detection limit
was determined. Following this approach, cytokinins and 3':5'-cAMP extracted from
only mg amounts of apical shoot meristem and chloroplasts obtained from Nicotiana
tabacum cv. Petit Havana SR1 were identified and quantified.

text: 'Although cytokinins (CKs) affect a number of processes connected with chloroplasts,
it has never been rigorously proven that chloroplasts contain CKs. We isolated
intact chloroplasts from tobacco (Nicotiana tabacum L. cv SR1) and wheat (Triticum
aestivum L. cv Ritmo) leaves and determined their CKs by liquid chromatography/tandem
mass spectroscopy. Chloroplasts from both species contained a whole spectrum of
CKs, including free bases (zeatin and isopentenyladenine), ribosides (zeatin riboside,
and isopentenyladenosine), ribotides (isopentenyladenosine-5′-monophosphate, zeatin
riboside-5′-monophosphate, and dihydrozeatin riboside-5′-monophosphate), and N-glucosides
(zeatin-N 9-glucoside, dihydrozeatin-N 9-glucoside, zeatin-N 7-glucoside, and
isopentenyladenine-N-glucosides). In chloroplasts there was a moderately higher
relative amount of bases, ribosides, and ribotides than in leaves, and a significantly
increased level ofN 9-glucosides of zeatin and dihydrozeatin. Tobacco and wheat
chloroplasts were prepared from leaves at the end of either a dark or light period.
After a dark period, chloroplasts accumulated more CKs than after a light period.
The differences were moderate for free bases and ribosides, but highly significant
for glucosides. Tobacco chloroplasts from dark-treated leaves contained zeatin
riboside-O-glucoside and dihydrozeatin riboside-O-glucoside, as well as a relatively
high CK oxidase activity. These data show that chloroplasts contain a whole spectrum
of CKs and the enzymatic activity necessary for their metabolism. '

text: This volume provides an overview of glutamate receptors and their role in
excitatory neurotransmission. It focusses on three aspects. First, it describes
the functional, molecular, and pharmacological properties of glutamate receptors
(AMPA, NMDA, and kainate receptors). Second, it gives a survey how these receptors
are involved in synaptic transmission at different glutamatergic synapses in the
mammalian CNS. Finally, it adresses how overactivation of glutamate receptors
can lead to excitotoxic cell death, and emphasizes the importance of glutamate
receptors as potential therapeutical targets. The chapters, written by leading
scientists, give accurate summaries of facets that have emerged recently in this
field. The book demonstrates the strength of a multidisciplinary approach involving
physiology, pharmacology, and molecular biology. It will be useful for other scientists
in and outside the field, lecturers and students at different educational levels.

text: Accurate proteolytic processing of neuropeptide and peptide hormone precursors
by members of the kexin/furin family of proteases is key to determining both the
identities and activities of signaling peptides. Here we identify amontillado
(amon), the Drosophila melanogaster homolog of the mammalian neuropeptide processing
protease PC2, and show that in contrast to vertebrate PC2, amontillado expression
undergoes extensive regulation in the nervous system during development. In situ
hybridization reveals that expression of amontillado is restricted to the final
stages of embryogenesis when it is found in anterior sensory structures and in
only 168 cells in the brain and ventral nerve cord. After larvae hatch from their
egg shells, the sensory structures and most cells in the CNS turn off or substantially
reduce amontillado expression, suggesting that amontillado plays a specific role
late in embryogenesis. Larvae lacking the chromosomal region containing amontillado
show no gross anatomical defects and respond to touch. However, such larvae show
a greatly reduced frequency of a hatching behavior of wild- type Drosophila in
which larvae swing their heads, scraping through the eggshell with their mouth
hooks. Ubiquitous expression of amontillado can restore near wild-type levels
of this behavior, whereas expression of amontillado with an alanine substitution
for the catalytic histidine cannot. These results suggest that amontillado expression
is regulated as part of a programmed modulation of neural signaling that controls
hatching behavior by producing specific neuropeptides in particular neurons at
an appropriate developmental time.

text: The redshift at which the universe was reionized is currently unknown. We
examine the optimal strategy for extracting this redshift, zreion, from the spectra
of early sources. For a source located at a redshift zs beyond but close to the
reionization redshift, (1 + zreion) < (1 + zs) < 32/27(1 + zreion), the Gunn-Peterson
trough splits into disjoint Lyα, Lyβ, and possibly higher Lyman series troughs,
with some transmitted flux between these troughs. We show that although the transmitted
flux is suppressed considerably by the dense Lyα forest at high redshifts, it
could still be detectable as long as zreion ≲ 8. If the ionizing sources are bright
and have a short duty cycle (e.g., if they are miniquasars or starbursts with
a lifetime ≲106 yr), then breakthrough occurs shortly after the H II regions around
them overlap, and the transmitted flux provides a measurement of zreion. The Next
Generation Space Telescope will reach the spectroscopic sensitivity required for
such a measurement.

text: It is currently unknown whether the universe was reionized by quasars or stars
at z ≳ 5. We point out that quasars can be best distinguished from stellar systems
by their X-ray emission. Based on a simple hierarchical CDM model, we predict
the number counts and X-ray fluxes of quasars at high redshifts. The model is
consistent with available data on the luminosity function of high-redshift quasars
in the optical and soft X-ray bands. The cumulative contribution of faint, undetected
quasars in our model is consistent with the unresolved fraction of the X-ray background.
We find that the Chandra X-ray Observatory might detect ~10^2 quasars from redshifts
z ≳ 5 per its 17' × 17' field of view at the flux threshold of ~2 × 10^-16 ergs
s^-1 cm^-2. The redshifts of these faint point sources could be identified by
follow-up infrared observations from the ground or with the Next Generation Space
Telescope.

text: Models are presented for the Lyα emission of dusty high-redshift galaxies
by combining the Press-Schechter formalism with a treatment of the inhomogeneous
dust distribution inside galaxies. It is found that the amount of Lyα radiation
escaping from the galaxies strongly depends on the time over which the dust is
produced through stellar activity and on the ambient inhomogeneity of the H II
regions that surround the ionizing OB stars. Good agreement is found with recent
observations, as well as with previous nondetections. Although a detailed determination
of the individual model parameters is precluded by uncertainties, we find that
(1) the dust content in primordial galaxies builds up in no more than ~5 × 108
yr, (2) the galactic H II regions are inhomogeneous with a cloud-covering factor
of order unity, and (3) the overall star formation efficiency is at least ~5%.
It is predicted that future observations can detect these Lyα galaxies up to redshifts
of ~8. If the universe is reionized at zr ≲ 8, the corresponding decline in the
number of Lyα emitters at z ≳ zr could prove to be a useful probe of the reionization
epoch.

text: "We examine various observable signatures of the first generation of stars
and low-luminosity quasars, including the metal enrichment, radiation background,
and dust opacity/emission that they produce. We calculate the formation history
of collapsed baryonic halos, based on an extension of the Press-Schechter formalism,
incorporating the effects of pressure and H2-dissociation. We then use the observed
C/H ratio at z=3 in the Lyman-α forest clouds to obtain an average the star formation
efficiency in these halos. Similarly, we fit the efficiency of black-hole formation,
and the shape of quasar light curves, to match the observed quasar luminosity
function (LF) between z=2−4, and use this fit to extrapolate the quasar LF to
faint magnitudes and high redshifts. To be consistent with the lack of faint point-sources
in the Hubble Deep Field, we impose a lower limit of ∼ 75 km s−1 for the circular
velocities of halos harboring central black holes.\r\nWe find that in a ΛCDM model,
stars reionize the IGM at zreion=9−13, and quasars at z=12. Observationally, zreion
can be measured by the forthcoming MAP and Planck Surveyor satellites, via the
damping of CMB anisotropies by ∼10% on small angular scales due to electron scattering.
We show that if reionization occurs later, at 5 ≲ zreion ≲ 10, then it can be
measured from the spectra of individual sources. We also find that the Next Generation
Space Telescope will be able to directly image about 1–40 star clusters, and a
few faint quasars, from z >10 per square arcminute. The amount of dust produced
by the first supernovae has an optical depth of τ=0.1−1 towards high redshift
sources, and the reprocessed UV flux of stars and quasars distorts the cosmic

text: High-resolution, deep-imaging surveys are instrumental in setting constraints
on semianalytical structure formation models in cold dark matter (CDM) cosmologies.
We show here that the lack of unresolved B-band "dropouts" with V>25 mag in the
Hubble Deep Field appears to be inconsistent with the number of "miniquasars"
expected if massive black holes form with a constant universal efficiency in all
CDM halos. To reconcile the models with the data, a mechanism is needed that suppresses
the formation of active nuclei in halos with circular velocities vcirc≲50-75 km
s-1. This feedback naturally arises because of the photoionization heating of
the gas by the UV background. We consider several alternative effects that would
help reducing the number of miniquasars and find that these cannot alone account
for the observed lack of detections. If reddening by dust can be neglected at
early epochs, consistency with the optical data also requires that the luminous
extent of dwarf galaxies at high redshifts be larger than a few percent of the
virial radii of their dark matter halos, in order not to overpredict the number
of pointlike B-band dropouts. Future deep observations in the J and H bands with
NICMOS might reveal several z≳5 objects per field or provide even stronger constraints
on the models than existing B, V, and I data.

text: Scanning tunneling microscopy (STM) has been used to characterize the structure
and electronic properties of molybdenum selenide (Mo6Se6) molecular wires. STM
images resolve the 0.45 nm unit cell repeat in isolated molecular wires and bundles
of wires. Tunneling spectroscopy measurements exhibit sharp peaks in the local
density of states that are consistent with the Van Hove singularities expected
for a one-dimensional (1D) system. These data have been compared with previous
band structure calculations. Preliminary measurements at 5 K show no evidence
of a gap opening at low temperatures. The implications of these results to metal-insulator
transitions in 1D systems are discussed.
