text: For any n ≧ 2, let F ∈ ℤ [ x 1, … , xn ] be a form of degree d≧ 2, which produces
a geometrically irreducible hypersurface in ℙn–1. This paper is concerned with
the number N(F;B) of rational points on F = 0 which have height at most B. For
any ε > 0 we establish the estimate N(F; B) = O(B n− 2+ ε ), whenever either
n ≦ 5 or the hypersurface is not a union of lines. Here the implied constant depends
at most upon d, n and ε.

is to produce better upper bounds for the number of integer solutions to the equation
F=0, that are restricted to lie in very lopsided boxes. As an application of the
main result, a new paucity estimate is obtained for equal sums of two like powers.

text: The human norepinephrine (NE) transporter (hNET) attenuates neuronal signaling
by rapid NE clearance from the synaptic cleft, and NET is a target for cocaine
and amphetamines as well as therapeutics for depression, obsessive-compulsive
disorder, and post-traumatic stress disorder. In spite of its central importance
in the nervous system, little is known about how NET substrates, such as NE, 1-methyl-4-tetrahydropyridinium
(MPP+), or amphetamine, interact with NET at the molecular level. Nor do we understand
the mechanisms behind the transport rate. Previously we introduced a fluorescent
substrate similar to MPP+, which allowed separate and simultaneous binding and
transport measurement (Schwartz, J. W., Blakely, R. D., and DeFelice, L. J. (2003)
J. Biol. Chem. 278, 9768-9777). Here we use this substrate, 4-(4-(dimethylamino)styrl)-N-methyl-pyridinium
(ASP+), in combination with green fluorescent protein-tagged hNETs to measure
substrate-transporter stoichiometry and substrate binding kinetics. Calibrated
confocal microscopy and fluorescence correlation spectroscopy reveal that hNETs,
which are homo-multimers, bind one substrate molecule per transporter subunit.
Substrate residence at the transporter, obtained from rapid on-off kinetics revealed
in fluorescence correlation spectroscopy, is 526 μs. Substrate residence obtained
by infinite dilution is 1000 times slower. This novel examination of substrate-transporter
kinetics indicates that a single ASP + molecule binds and unbinds thousands of
times before being transported or ultimately dissociated from hNET. Calibrated
fluorescent images combined with mass spectroscopy give a transport rate of 0.06
ASP +/hNET-protein/s, thus 36,000 on-off binding events (and 36 actual departures)
occur for one transport event. Therefore binding has a low probability of resulting
in transport. We interpret these data to mean that inefficient binding could contribute
to slow transport rates.

text: This book contains a unique survey of the mathematically rigorous results
about the quantum-mechanical many-body problem that have been obtained by the
authors in the past seven years. It addresses a topic that is not only rich mathematically,
using a large variety of techniques in mathematical analysis, but is also one
with strong ties to current experiments on ultra-cold Bose gases and Bose-Einstein
condensation. The book provides a pedagogical entry into an active area of ongoing
research for both graduate students and researchers. It is an outgrowth of a course
given by the authors for graduate students and post-doctoral researchers at the
Oberwolfach Research Institute in 2004. The book also provides a coherent summary
of the field and a reference for mathematicians and physicists active in research
on quantum mechanics.

Now that the low temperature properties of quantum-mechanical many-body systems (bosons) at low density, ρ, can be examined experimentally it is appropriate to revisit some of the formulas deduced by many authors 4–5 decades ago, and to explore new regimes not treated before. For systems with repulsive (i.e. positive) interaction potentials the experimental low temperature state and the ground state are effectively synonymous — and this fact is used in all modeling. In such cases, the leading term in the energy/particle is 2πħ2 aρ/m where a is the scattering length of the two-body potential. Owing to the delicate and peculiar nature of bosonic correlations (such as the strange N 7/5 law for charged bosons), four decades of research failed to establish this plausible formula rigorously. The only previous lower bound for the energy was found by Dyson in 1957, but it was 14 times too small. The correct asymptotic formula has been obtained by us and this work will be presented. The reason behind the mathematical difficulties will be emphasized. A different formula, postulated as late as 1971 by Schick, holds in two dimensions and this, too, will be shown to be correct. With the aid of the methodology developed to prove the lower bound for the homogeneous gas, several other problems have been successfully addressed. One is the proof by us that the Gross-Pitaevskii equation correctly describes the ground state in the ‘traps’ actually used in the experiments. For this system it is also possible to prove complete Bose condensation and superfluidity as we have shown. On the frontier of experimental developments is the possibility that a dilute gas in an elongated trap will behave like a one-dimensional system; we have proved this mathematically. Another topic is a proof that Foldy’s 1961 theory of a high density Bose gas of charged particles correctly describes its ground state energy; using this we can also prove the N 7/5 formula for the ground state energy of the two-component charged Bose gas proposed by Dyson in 1967. All of this is quite recent work and it is hoped that the mathematical methodology might be useful, ultimately, to solve more complex problems connected with these interesting systems.

text: The validity of substituting a c-number z for the k = 0 mode operator a0 is
established rigorously in full generality, thereby verifying one aspect of Bogoliubov's
1947 theory. This substitution not only yields the correct value of thermodynamic
quantities such as the pressure or ground state energy, but also the value of
|z|2 that maximizes the partition function equals the true amount of condensation
in the presence of a gauge-symmetry-breaking term. This point had previously been
elusive.

text: The strong subadditivity of entropy plays a key role in several areas of physics
and mathematics. It states that the entropy S[±]=- Tr(ϱlnϱ) of a density matrix
ϱ123 on the product of three Hilbert spaces satisfies S[ϱ123]- S[ϱ12]≤S[ϱ23]-S[ϱ2].
We strengthen this to S[ϱ123]-S[ϱ12] ≤αnα(S[ϱ23α]-S[ϱ2α]), where the nα are
weights and the ϱ23α are partitions of ϱ23. Correspondingly, there is a strengthening
of the theorem that the map A|Trexp[L+lnA] is concave. As applications we prove
some monotonicity and convexity properties of the Wehrl coherent state entropy
and entropy inequalities for quantum gases.

text: Recent developments in the physics of low-density trapped gases make it worthwhile
to verify old, well-known results that, while plausible, were based on perturbation
theory and assumptions about pseudopotentials. We use and extend recently developed
techniques to give a rigorous derivation of the asymptotic formula for the ground-state
energy of a dilute gas of N fermions interacting with a short-range, positive
potential of scattering length a. For spin-12 fermions, this is E∼E0+(22m)2πNa,
where E0 is the energy of the noninteracting system and is the density. A similar
formula holds in two dimensions (2D), with a replaced by ln(a2). Obviously this
2D energy is not the expectation value of a density-independent pseudopotential.

text: Intersection graphs of disks and of line segments, respectively, have been
well studied, because of both practical applications and theoretically interesting
properties of these graphs. Despite partial results, the complexity status of
the Clique problem for these two graph classes is still open. Here, we consider
the Clique problem for intersection graphs of ellipses, which, in a sense, interpolate
between disks and line segments, and show that the problem is APX-hard in that
case. Moreover, this holds even if for all ellipses, the ratio of the larger over
the smaller radius is some prescribed number. Furthermore, the reduction immediately
carries over to intersection graphs of triangles. To our knowledge, this is the
first hardness result for the Clique problem in intersection graphs of convex
objects with finite description complexity. We also describe a simple approximation
algorithm for the case of ellipses for which the ratio of radii is bounded.

text: We consider an online version of the conflict-free coloring of a set of points
on the line, where each newly inserted point must be assigned a color upon insertion,
and at all times the coloring has to be conflict-free, in the sense that in every
interval I there is a color that appears exactly once in I. We present several
deterministic and randomized algorithms for achieving this goal, and analyze their
performance, that is, the maximum number of colors that they need to use, as a
function of the number n of inserted points. We first show that a natural and
simple (deterministic) approach may perform rather poorly, requiring Ω(√n) colors
in the worst case. We then modify this approach, to obtain an efficient deterministic
algorithm that uses a maximum of Θ(log 2 n) colors. Next, we present two randomized
solutions. The first algorithm requires an expected number of at most O(log 2
n) colors, and produces a coloring which is valid with high probability, and the
second one, which is a variant of our efficient deterministic algorithm, requires
an expected number of at most O(log n log log n) colors but always produces a
valid coloring. We also analyze the performance of the simplest proposed algorithm
when the points are inserted in a random order, and present an incomplete analysis
that indicates that, with high probability, it uses only O(log n) colors. Finally,
we show that in the extension of this problem to two dimensions, where the relevant
ranges are disks, n colors may be required in the worst case. The average-case
behavior for disks, and cases involving other planar ranges, are still open.

text: Local accumulation of the plant growth regulator auxin mediates pattern formation
in Arabidopsis roots and influences outgrowth and development of lateral root-
and shoot-derived primordia. However, it has remained unclear how auxin can simultaneously
regulate patterning and organ outgrowth and how its distribution is stabilized
in a primordium-specif ic manner. Here we show that five PIN genes collectively
control auxin distribution to regulate cell division and cell expansion in the
primary root. Furthermore, the joint action of these genes has an important role
in pattern formation by focusing the auxin maximum and restricting the expression
domain of PLETHORA (PLT) genes, major determinants for root stem cell specification.
In turn, PLT genes are required for PIN gene transcription to stabilize the auxin
maximum at the distal root tip. Our data reveal an interaction network of auxin
transport facilitators and root fate determinants that control patterning and
growth of the root primordium.

text: 'A systematic study of the morphology of self-organized islands in the InAs/GaAs(0
0 1) and Ge/Si(0 0 1) systems is presented, based on high-resolution scanning
tunneling microscopy measurements. We demonstrate that in both cases two main
island families coexist: smaller pyramids bound by one type of shallow facets
and larger multifaceted domes. Their structure and facet orientation are precisely
determined, thus solving a highly debated argument in the case of InAs/GaAs(0
0 1). The comparison between the two material systems reveals the existence of
striking similarities that extend even to the nature of island precursors and
to the islands that form when depositing InGaAs or GeSi alloys. The implications
of these observations on a possible universal description of the Stranski-Krastanow
growth mode are discussed with respect to recent theoretical results.'

text: SiGe islands move laterally on a Si(001) substrate during in situ postgrowth
annealing. This surprising behavior is revealed by an analysis of the substrate
surface morphology after island removal using wet chemical etching. We explain
the island motion by asymmetric surface-mediated alloying. Material leaves one
side of the island by surface diffusion, and mixes with additional Si from the
surrounding surface as it redeposits on the other side. Thus the island moves
laterally while becoming larger and more dilute.

text: The effects of substrate temperature, growth rate, and postgrowth annealing
on the composition of Ge islands grown on Si(001) were investigated with a combination
of selective wet chemical etching and atomic force microscopy. A simple kinetic
model comprising only surface diffusion processes can explain all the experimentally
observed compositional profiles for pyramid and dome islands grown in the 560-620°C
range. From this model three-dimensional compositional maps were extracted. By
performing annealing experiments a change in the composition of the domes was
observed. This could be explained as the result of the islands' movement induced
by alloying-driven energy minimization. Also in this case kinetically hindered
bulk diffusion processes are not needed to explain the experimental observations.

text: Laterally aligned multilayer GeSiSi islands grown on a patterned Si (001)
substrate are disclosed by selective etching of Si in a KOH solution. This procedure
allows us to visualize the vertical alignment of the islands in a three-dimensional
perspective. Our technique reveals that partly coalesced double islands in the
initial layer do not merge together, but instead gradually reproduce into well-separated
double islands in upper layers. We attribute this effect to very thin spacer layers,
which efficiently transfer the strain modulation of each island through the spacer
layer to the surface. The etching rate of Si is reduced in tensile strained regions,
which helps to preserve sufficient Si between the stacked islands to form a periodic
array of freestanding and vertically modulated heterostructure pillars.

text: This paper presents optical duobinary and dicode signalling, as alternatives
to the binary format, in order to improve the transmission performance in the
presense of non-linear effects in a dense wavelength division multiplex (WDM)
optical system. Duobinary signalling is applied to an optical system to explore
the reduction of stimulated Brillouin scattering (SBS) effects. Duobinary signalling
suppresses the SBS effects, and an eye-opening improvement of 0.25 to 1.2 dB is
achieved relative to binary transmission over a range of input power levels. An
experimental study demonstrates that duobinary modulation suppresses the four
wave mixing (FWM) products of a dense WDM system by a maximum of 3 dB. The suppression
is maintained over a range of channel spacings. An investigation of the impact
of fibre dispersion on FWM products under binary, duobinary and dicode modulation
in a dense WDM system is then performed, with interchannel spacing and optical
power variation. This leads to the development of a set of guidelines for the
application areas, in which it is appropriate to use duobinary or dicode modulation
in WDM systems as a means of mitigating the impact of FWM.
