text: We consider the supersymmetric quantum mechanical system which is obtained
by dimensionally reducing d = 6, N = 1 supersymmetric gauge theory with gauge
group U(1) and a single charged hypermultiplet. Using the deformation method and
ideas introduced by Porrati and Rozenberg [1], we present a detailed proof of
the existence of a normalizable ground state for this system.

text: We study the long time evolution of a quantum particle interacting with a
random potential in the Boltzmann-Grad low density limit. We prove that the phase
space density of the quantum evolution defined through the Husimi function converges
weakly to a linear Boltzmann equation. The Boltzmann collision kernel is given
by the full quantum scattering cross-section of the obstacle potential.

text: We present the results of an experimental investigation into the nature and
structure of turbulent pipe flow at moderate Reynolds numbers. A turbulence regeneration
mechanism is identified which sustains a symmetric traveling wave within the flow.
The periodicity of the mechanism allows comparison to the wavelength of numerically
observed exact traveling wave solutions and close agreement is found. The advection
speed of the upstream turbulence laminar interface in the experimental flow is
observed to form a lower bound on the phase velocities of the exact traveling
wave solutions. Overall our observations suggest that the dynamics of the turbulent
flow at moderate Reynolds numbers are governed by unstable nonlinear traveling
waves.

text: Transitional pipe flow is investigated in two different experimental set-ups.
In the first the stability threshold and the initial growth of localized perturbations
are studied. Good agreement is found with an earlier investigation of the transition
threshold. The measurement technique applied in the last part of this study allows
the reconstruction of the streamwise vorticity in a turbulent puff.

text: We present the results of an experimental investigation of the effect of a
magnetic field on the stability of convection in a liquid metal. A rectangular
container of gallium is subjected to a horizontal temperature gradient and a uniform
magnetic field is applied separately in three directions. The magnetic field suppresses
the oscillation most effectively when it is applied in the vertical direction
and is least efficient when applied in the direction of the temperature gradient.
The critical temperature difference required for the onset of oscillations is
found to scale exponentially with the magnitude of the magnetic field for all
three orientations. Comparisons are made with available theory and qualitative
differences are discussed.

text: The plant hormone auxin elicits many specific context-dependent developmental
responses. Auxin promotes degradation of Aux/IAA proteins that prevent transcription
factors of the auxin response factor (ARF) family from regulating auxin-responsive
target genes. Aux/IAAs and ARFs are represented by large gene families in Arabidopsis.
Here we show that stabilization of BDL/IAA12 or its sister protein IAA13 prevents
MP/ARF5-dependent embryonic root formation whereas stabilized SHY2/IAA3 interferes
with seedling growth. Although both bdl and shy2-2 proteins inhibited MP/ARF5-dependent
reporter gene activation, shy2-2 was much less efficient than bdl to interfere
with embryonic root initiation when expressed from the BDL promoter. Similarly,
MP was much more efficient than ARF16 in this process. When expressed from the
SHY2 promoter, both shy2-2 and bdl inhibited cell elongation and auxin-induced
gene expression in the seedling hypocotyl. By contrast, gravitropism and auxin-induced
gene expression in the root, which were promoted by functionally redundant NPH4/ARF7
and ARF19 proteins, were inhibited by shy2-2, but not by bdl protein. Our results
suggest that auxin signals are converted into specific responses by matching pairs
of coexpressed ARF and Aux/IAA proteins.

text: One of the fundamental properties of the immune system is its capacity to
avoid autoimmune diseases. The mechanism underlying this process, known as self-tolerance,
is hitherto unresolved but seems to involve the control of clonal expansion of
autoreactive lymphocytes. This article reviews mathematical modeling of self-tolerance,
addressing two specific hypotheses. The first hypothesis posits that self-tolerance
is mediated by tuning of activation thresholds, which makes autoreactive T lymphocytes
reversibly "anergic" and unable to proliferate. The second hypothesis
posits that the proliferation of autoreactive T lymphocytes is instead controlled
by specific regulatory T lymphocytes. Models representing the population dynamics
of autoreactive T lymphocytes according to these two hypotheses were derived.
For each model we identified how cell density affects tolerance, and predicted
the corresponding phase spaces and bifurcations. We show that the simple induction
of proliferative anergy, as modeled here, has a density dependence that is only
partially compatible with adoptive transfers of tolerance, and that the models
of tolerance mediated by specific regulatory T cells are closer to the observations.

text: In plants, cell polarity is an issue more recurring than in other systems,
because plants, due to their adaptive and flexible development, often change cell
polarity postembryonically according to intrinsic cues and demands of the environment.
Recent findings on the directional movement of the plant signalling molecule auxin
provide a unique connection between individual cell polarity and the establishment
of polarity at the tissue, organ, and whole-plant levels. Decisions about the
subcellular polar targeting of PIN auxin transport components determine the direction
of auxin flow between cells and consequently mediate multiple developmental events.
In addition, mutations or chemical interference with PIN-based auxin transport
result in abnormal cell divisions. Thus, the complicated links between cell polarity
establishment, auxin transport, cytoskeleton, and oriented cell divisions now
begin to emerge. Here we review the available literature on the issues of cell
polarity in both plants and animals to extend our understanding on the generation,
maintenance, and transmission of cell polarity in plants.

text: 'One of the mechanisms by which signalling molecules regulate cellular behaviour
is modulating subcellular protein translocation. This mode of regulation is often
based on specialized vesicle trafficking, termed constitutive cycling, which consists
of repeated internalization and recycling of proteins to and from the plasma membrane.
No such mechanism of hormone action has been shown in plants although several
proteins, including the PIN auxin efflux facilitators, exhibit constitutive cycling.
Here we show that a major regulator of plant development, auxin, inhibits endocytosis.
This effect is specific to biologically active auxins and requires activity of
the Calossin-like protein BIG. By inhibiting the internalization step of PIN constitutive
cycling, auxin increases levels of PINs at the plasma membrane. Concomitantly,
auxin promotes its own efflux from cells by a vesicle-trafficking-dependent mechanism.
Furthermore, asymmetric auxin translocation during gravitropism is correlated
with decreased PIN internalization. Our data imply a previously undescribed mode
of plant hormone action: by modulating PIN protein trafficking, auxin regulates
PIN abundance and activity at the cell surface, providing a mechanism for the
feedback regulation of auxin transport.'

text: 'Plant development displays an exceptional plasticity and adaptability that
involves the dynamic, asymmetric distribution of the phytohormone auxin. Polar
auxin flow, which requires polarly localized transport facilitators of the PIN
family, largely contributes to the establishment and maintenance of the auxin
gradients. Functionally overlapping action of PIN proteins mediates multiple developmental
processes, including embryo formation, organ development and tropisms. Here we
show that PIN proteins exhibit synergistic interactions, which involve cross-regulation
of PIN gene expression in pin mutants or plants with inhibited auxin transport.
Auxin itself positively feeds back on PIN gene expression in a tissue-specific
manner through an AUX/IAA-dependent signalling pathway. This regulatory switch
is indicative of a mechanism by which the loss of a specific PIN protein is compensated
for by auxin-dependent ectopic: expression of its homologues. The compensatory
properties of the PIN-dependent transport network might enable the stabilization
of auxin gradients and potentially contribute to the robustness of plant adaptive
development.'

text: Molecular mechanisms of pattern formation in the plant embryo are not well
understood. Recent molecular and cellular studies, in conjunction with earlier
microsurgical, physiological, and genetic work, are now starting to define the
outlines of a model where gradients of the signaling molecule auxin play a central
role in embryo patterning. It is relatively clear how these gradients are established
and interpreted, but how they are maintained is still unresolved. Here, we have
studied the contributions of auxin biosynthesis, conjugation, and transport pathways
to the maintenance of embryonic auxin gradients. Auxin homeostasis in the embryo
was manipulated by region-specific conditional expression of indoleacetic acid-tryptophan
monooxygenase or indoleacetic acid-lysine synthetase, bacterial enzymes for auxin
biosynthesis or conjugation. Neither manipulation of auxin biosynthesis nor of
auxin conjugation interfered with auxin gradients and patterning in the embryo.
This result suggests a compensatory mechanism for buffering auxin gradients in
the embryo. Chemical and genetic inhibition revealed that auxin transport activity,
in particular that of the PIN-FORMED1 (PIN1) and PIN4 proteins, is a major factor
in the maintenance of these gradients.

text: The two actin-related subunits of the Arp2/3 complex, Arp2 and Arp3, are proposed
to form a pseudo actin dimer that nucleates actin polymerization. However, in
the crystal structure of the inactive complex, they are too far apart to form
such a nucleus. Here, we show using EM that yeast and bovine Arp2/3 complexes
exist in a distribution among open, intermediate and closed conformations. The
crystal structure docks well into the open conformation. The activator WASp binds
at the cleft between Arp2 and Arp3, and all WASp-bound complexes are closed. The
inhibitor coronin binds near the p35 subunit, and all coronin-bound complexes
are open. Activating and loss-of-function mutations in the p35 subunit skew conformational
distribution in opposite directions, closed and open, respectively. We conclude
that WASp stabilizes p35-dependent closure of the complex, holding Arp2 and Arp3
closer together to nucleate an actin filament.

text: Two ETS transcription factors of the Pea3 subfamily are induced in subpopulations
of dorsal root ganglion (DRG) sensory and spinal motor neurons by target-derived
factors. Their expression controls late aspects of neuronal differentiation such
as target invasion and branching. Here, we show that the late onset of ETS gene
expression is an essential requirement for normal sensory neuron differentiation.
We provide genetic evidence in the mouse that precocious ETS expression in DRG
sensory neurons perturbs axonal projections, the acquisition of terminal differentiation
markers, and their dependence on neurotrophic support. Together, our findings
indicate that DRG sensory neurons exhibit a temporal developmental switch that
can be revealed by distinct responses to ETS transcription factor signaling at
sequential steps of neuronal maturation.

text: This paper addresses the novel problem of automatically synthesizing an output
image from a large collection of different input images. The synthesized image,
called a digital tapestry, can be viewed as a visual summary or a virtual 'thumbnail'
of all the images in the input collection. The problem of creating the tapestry
is cast as a multi-class labeling problem such that each region in the tapestry
is constructed from input image blocks that are salient and such that neighboring
blocks satisfy spatial compatibility. This is formulated using a Markov Random
Field and optimized via the graph cut based expansion move algorithm. The standard
expansion move algorithm can only handle energies with metric terms, while our
energy contains non-metric (soft and hard) constraints. Therefore we propose two
novel contributions. First, we extend the expansion move algorithm for energy
functions with non-metric hard constraints. Secondly, we modify it for functions
with "almost" metric soft terms, and show that it gives good results
in practice. The proposed framework was tested on several consumer photograph
collections, and the results are presented.

This paper demonstrates the high quality, real-time segmentation techniques. We achieve real-time segmentation of foreground from background layers in stereo video sequences. Automatic separation of layers from colour/contrast or from stereo alone is known to be error-prone. Here, colour, contrast and stereo matching information are fused to infer layers accurately and efficiently. The first algorithm, layered dynamic programming (LDP), solves stereo in an extended 6-state space that represents both foreground/background layers and occluded regions. The stereo-match likelihood is then fused with a contrast-sensitive colour model that is learned on the fly, and stereo disparities are obtained by dynamic programming. The second algorithm, layered graph cut (LGC), does not directly solve stereo. Instead the stereo match likelihood is marginalised over foreground and background hypotheses, and fused with a contrast-sensitive colour model like the one used in LDP. Segmentation is solved efficiently by ternary graph cut. Both algorithms are evaluated with respect to ground truth data and found to have similar performance, substantially better than stereo or colour/contrast alone. However, their characteristics with respect to computational efficiency are rather different. The algorithms are demonstrated in the application of background substitution and shown to give good quality composite video output.

text: Tree-reweighted max-product (TRW) message passing [9] is a modified form of
the ordinary max-product algorithm for attempting to find minimal energy configurations
in Markov random field with cycles. For a TRW fixed point satisfying the strong
tree agreement condition, the algorithm outputs a configuration that is provably
optimal. In this paper, we focus on the case of binary variables with pairwise
couplings, and establish stronger properties of TRW fixed points that satisfy
only the milder condition of weak tree agreement (WTA). First, we demonstrate
how it is possible to identify part of the optimal solution - i.e., a provably
optimal solution for a subset of nodes - without knowing a complete solution.
Second, we show that for submodular functions, a WTA fixed point always yields
a globally optimal solution. We establish that for binary variables, any WTA fixed
point always achieves the global maximum of the linear programming relaxation
underlying the TRW method.

text: In the work of the authors (2003), we showed that graph cuts can find hypersurfaces
of globally minimal length (or area) under any Riemannian metric. Here we show
that graph cuts on directed regular grids can approximate a significantly more
general class of continuous non-symmetric metrics. Using submodularity condition
(Boros and Hammer, 2002 and Kolmogorov and Zabih, 2004), we obtain a tight characterization
of graph-representable metrics. Such "submodular" metrics have an elegant
geometric interpretation via hypersurface functionals combining length/area and
flux. Practically speaking, we attend 'geo-cuts' algorithm to a wider class of
geometrically motivated hypersurface functionals and show how to globally optimize
any combination of length/area and flux of a given vector field. The concept of
flux was recently introduced into computer vision by Vasilevskiy and Siddiqi (2002)
but it was mainly studied within variational framework so far. We are first to
show that flux can be integrated into graph cuts as well. Combining geometric
concepts of flux and length/area within the global optimization framework of graph
cuts allows principled discrete segmentation models and advances the slate of
the art for the graph cuts methods in vision. In particular we address the "shrinking"
problem of graph cuts, improve segmentation of long thin objects, and introduce
useful shape constraints.

text: We present an improved bound on the advantage of any q-query adversary at
distinguishing between the CBC MAC over a random n-bit permutation and a random
function outputting n bits. The result assumes that no message queried is a prefix
of any other, as is the case when all messages to be MACed have the same length.
We go on to give an improved analysis of the encrypted CBC MAC, where there is
no restriction on queried messages. Letting m be the block length of the longest
query, our bounds are about mq2/2n for the basic CBC MAC and mo(1)q2/2n for the
encrypted CBC MAC, improving prior bounds of m2q2/2n. The new bounds translate
into improved guarantees on the probability of forging these MACs.

The Full-Domain Hash (FDH) signature scheme [3] forms one the most basic usages of random oracles. It works with a family F of trapdoor permutations (TDP), where the signature of m is computed as f−1(h(m)) (here f ∈R F and h is modelled as a random oracle). It is known to be existentially unforgeable for any TDP family F [3], although a much tighter security reduction is known for a restrictive class of TDP’s [10,14] — namely, those induced by a family of claw-free permutations (CFP) pairs. The latter result was shown [11] to match the best possible “black-box” security reduction in the random oracle model, irrespective of the TDP family F (e.g., RSA) one might use.
In this work we investigate the question if it is possible to instantiate the random oracle h with a “real” family of hash functions H such that the corresponding schemes can be proven secure in the standard model, under some natural assumption on the family F. Our main result rules out the existence of such instantiations for any assumption on F which (1) is satisfied by a family of random permutations; and (2) does not allow the attacker to invert f ∈R F on an a-priori unbounded number of points. Moreover, this holds even if the choice of H can arbitrarily depend on f. As an immediate corollary, we rule out instantiating FDH based on general claw-free permutations, which shows that in order to prove the security of FDH in the standard model one must utilize significantly more structure on F than what is sufficient for the best proof of security in the random oracle model.
