text: We introduce an (equi-)affine invariant geometric structure by which surfaces
that go through squeeze and shear transformations can still be properly analyzed.
The definition of an affine invariant metric enables us to evaluate a new form
of geodesic distances and to construct an invariant Laplacian from which local
and global diffusion geometry is constructed. Applications of the proposed framework
demonstrate its power in generalizing and enriching the existing set of tools
for shape analysis.

text: Region feature detectors and descriptors have become a successful and popular
alternative to point descriptors in image analysis due to their high robustness
and repeatability, leading to a significant interest in the shape analysis community
in finding analogous approaches in the 3D world. Recent works have successfully
extended the maximally stable extremal region (MSER) detection algorithm to surfaces.
In many applications, however, a volumetric shape model is more appropriate, and
modeling shape deformations as approximate isometries of the volume of an object,
rather than its boundary, better captures natural behavior of non-rigid deformations.
In this paper, we formulate a diffusion-geometric framework for volumetric stable
component detection and description in deformable shapes. An evaluation of our
method on the SHREC'11 feature detection benchmark and SCAPE human body scans
shows its potential as a source of high-quality features. Examples demonstrating
the drawbacks of surface stable components and the advantage of their volumetric
counterparts are also presented.

text: 'In this work, we present intrinsic shape context (ISC) descriptors for 3D
shapes. We generalize to surfaces the polar sampling of the image domain used
in shape contexts: for this purpose, we chart the surface by shooting geodesic
outwards from the point being analyzed; `angle'' is treated as tantamount to geodesic
shooting direction, and radius as geodesic distance. To deal with orientation
ambiguity, we exploit properties of the Fourier transform. Our charting method
is intrinsic, i.e., invariant to isometric shape transformations. The resulting
descriptor is a meta-descriptor that can be applied to any photometric or geometric
property field defined on the shape, in particular, we can leverage recent developments
in intrinsic shape analysis and construct ISC based on state-of-the-art dense
shape descriptors such as heat kernel signatures. Our experiments demonstrate
a notable improvement in shape matching on standard benchmarks.'

text: We consider the problem of minimum distortion intrinsic correspondence between
deformable shapes, many useful formulations of which give rise to the NP-hard
quadratic assignment problem (QAP). Previous attempts to use the spectral relaxation
have had limited success due to the lack of sparsity of the obtained “fuzzy” solution.
In this paper, we adopt the recently introduced alternative L 1 relaxation of
the QAP based on the principles of game theory. We relate it to the Gromov and
Lipschitz metrics between metric spaces and demonstrate on state-of-the-art benchmarks
that the proposed approach is capable of finding very accurate sparse correspondences
between deformable shapes.

text: SIFT-like local feature descriptors are ubiquitously employed in computer
vision applications such as content-based retrieval, video analysis, copy detection,
object recognition, photo tourism, and 3D reconstruction. Feature descriptors
can be designed to be invariant to certain classes of photometric and geometric
transformations, in particular, affine and intensity scale transformations. However,
real transformations that an image can undergo can only be approximately modeled
in this way, and thus most descriptors are only approximately invariant in practice.
Second, descriptors are usually high dimensional (e.g., SIFT is represented as
a 128--dimensional vector). In large-scale retrieval and matching problems, this
can pose challenges in storing and retrieving descriptor data. We map the descriptor
vectors into the Hamming space in which the Hamming metric is used to compare
the resulting representations. This way, we reduce the size of the descriptors
by representing them as short binary strings and learn descriptor invariance from
examples. We show extensive experimental validation, demonstrating the advantage
of the proposed approach.

text: We consider the mass-critical generalized Korteweg{de Vries equation (∂t +
∂xxx)u = ±∂ x(u 5) for real-valued functions u(t; x). We prove that if the global
well-posedness and scattering conjecture for this equation failed, then, conditional
on a positive answer to the global well-posedness and scattering conjecture for
the masscritical nonlinear Schrffodinger equation (-i∂ t + ∂xx)u = ±(|u| 4u),
there exists a minimal-mass blowup solution to the mass-critical generalized KdV
equation which is almost periodic modulo the symmetries of the equation. Moreover,
we can guarantee that this minimal-mass blowup solution is either a self-similar
solution, a soliton-like solution, or a double high-to-low frequency cascade solution.

text: Spontaneous postsynaptic currents (PSCs) provide key information about the
mechanisms of synaptic transmission and the activity modes of neuronal networks.
However, detecting spontaneous PSCs in vitro and in vivo has been challenging,
because of the small amplitude, the variable kinetics, and the undefined time
of generation of these events. Here, we describe a, to our knowledge, new method
for detecting spontaneous synaptic events by deconvolution, using a template that
approximates the average time course of spontaneous PSCs. A recorded PSC trace
is deconvolved from the template, resulting in a series of delta-like functions.
The maxima of these delta-like events are reliably detected, revealing the precise
onset times of the spontaneous PSCs. Among all detection methods, the deconvolution-based
method has a unique temporal resolution, allowing the detection of individual
events in high-frequency bursts. Furthermore, the deconvolution-based method has
a high amplitude resolution, because deconvolution can substantially increase
the signal/noise ratio. When tested against previously published methods using
experimental data, the deconvolution-based method was superior for spontaneous
PSCs recorded in vivo. Using the high-resolution deconvolution-based detection
algorithm, we show that the frequency of spontaneous excitatory postsynaptic currents
in dentate gyrus granule cells is 4.5 times higher in vivo than in vitro.

text: There is a long-running controversy about how early cell fate decisions are
made in the developing mammalian embryo. 1,2 In particular, it is controversial
when the first events that can predict the establishment of the pluripotent and
extra-embryonic lineages in the blastocyst of the pre-implantation embryo occur.
It has long been proposed that the position and polarity of cells at the 16- to
32-cell stage embryo influence their decision to either give rise to the pluripotent
cell lineage that eventually contributes to the inner cell mass (ICM), comprising
the primitive endoderm (PE) and the epiblast (EPI), or the extra-embryonic trophectoderm
(TE) surrounding the blastocoel. The positioning of cells in the embryo at this
developmental stage could largely be the result of random events, making this
a stochastic model of cell lineage allocation. Contrary to such a stochastic model,
some studies have detected putative differences in the lineage potential of individual
blastomeres before compaction, indicating that the first cell fate decisions may
occur as early as at the 4-cell stage. Using a non-invasive, quantitative in vivo
imaging assay to study the kinetic behavior of Oct4 (also known as POU5F1), a
key transcription factor (TF) controlling pre-implantation development in the
mouse embryo, 3-5 a recent study identifies Oct4 kinetics as a predictive measure
of cell lineage patterning in the early mouse embryo. 6 Here, we discuss the implications
of such molecular heterogeneities in early development and offer potential avenues
toward a mechanistic understanding of these observations, contributing to the
resolution of the controversy of developmental cell lineage allocation.

text: Leakage resilient cryptography attempts to incorporate side-channel leakage
into the black-box security model and designs cryptographic schemes that are provably
secure within it. Informally, a scheme is leakage-resilient if it remains secure
even if an adversary learns a bounded amount of arbitrary information about the
schemes internal state. Unfortunately, most leakage resilient schemes are unnecessarily
complicated in order to achieve strong provable security guarantees. As advocated
by Yu et al. [CCS’10], this mostly is an artefact of the security proof and in
practice much simpler construction may already suffice to protect against realistic
side-channel attacks. In this paper, we show that indeed for simpler constructions
leakage-resilience can be obtained when we aim for relaxed security notions where
the leakage-functions and/or the inputs to the primitive are chosen non-adaptively.
For example, we show that a three round Feistel network instantiated with a leakage
resilient PRF yields a leakage resilient PRP if the inputs are chosen non-adaptively
(This complements the result of Dodis and Pietrzak [CRYPTO’10] who show that if
a adaptive queries are allowed, a superlogarithmic number of rounds is necessary.)
We also show that a minor variation of the classical GGM construction gives a
leakage resilient PRF if both, the leakage-function and the inputs, are chosen
non-adaptively.

text: "We propose a new authentication protocol that is provably secure based on
a ring variant of the learning parity with noise (LPN) problem. The protocol follows
the design principle of the LPN-based protocol from Eurocrypt’11 (Kiltz et al.),
and like it, is a two round protocol secure against active attacks. Moreover,
our protocol has small communication complexity and a very small footprint which
makes it applicable in scenarios that involve low-cost, resource-constrained devices.\r\n\r\nPerformance-wise,
our protocol is more efficient than previous LPN-based schemes, such as the many
variants of the Hopper-Blum (HB) protocol and the aforementioned protocol from
Eurocrypt’11. Our implementation results show that it is even comparable to the
standard challenge-and-response protocols based on the AES block-cipher. Our basic
protocol is roughly 20 times slower than AES, but with the advantage of having

memory are available to allow the storage of some off-line pre-computations, then
the online phase of our protocols is only twice as slow as AES.\r\n"

text: Interface theories provide a formal framework for component-based development
of software and hardware which supports the incremental design of systems and
the independent implementability of components. These capabilities are ensured
through mathematical properties of the parallel composition operator and the refinement
relation for components. More recently, a conjunction operation was added to interface
theories in order to provide support for handling multiple viewpoints, requirements
engineering, and component reuse. Unfortunately, the conjunction operator does
not allow independent implementability in general. In this paper, we study conditions
that need to be imposed on interface models in order to enforce independent implementability
with respect to conjunction. We focus on multiple viewpoint specifications and
propose a new compatibility criterion between two interfaces, which we call orthogonality.
We show that orthogonal interfaces can be refined separately, while preserving
both orthogonality and composability with other interfaces. We illustrate the
independent implementability of different viewpoints with a FIFO buffer example.

text: A boundary element model of a tunnel running through horizontally layered
soil with anisotropic material properties is presented. Since there is no analytical
fundamental solution for wave propagation inside a layered orthotropic medium
in 3D, the fundamental displacements and stresses have to be calculated numerically.
In our model this is done in the Fourier domain with respect to space and time.
The assumption of a straight tunnel with infinite extension in the x direction
makes it possible to decouple the system for every wave number kx, leading to
a 2.5D-problem, which is suited for parallel computation. The special form of
the fundamental solution, resulting from our Fourier ansatz, and the fact, that
the calculation of the boundary integral equation is performed in the Fourier
domain, enhances the stability and efficiency of the numerical calculations.

text: Computing the topology of an algebraic plane curve C means computing a combinatorial
graph that is isotopic to C and thus represents its topology in R2. We prove that,
for a polynomial of degree n with integer coefficients bounded by 2ρ, the topology
of the induced curve can be computed with bit operations ( indicates that we
omit logarithmic factors). Our analysis improves the previous best known complexity
bounds by a factor of n2. The improvement is based on new techniques to compute
and refine isolating intervals for the real roots of polynomials, and on the consequent
amortized analysis of the critical fibers of the algebraic curve.

text: 'We consider two-player stochastic games played on finite graphs with reachability
objectives where the first player tries to ensure a target state to be visited
almost-surely (i.e., with probability 1), or positively (i.e., with positive probability),
no matter the strategy of the second player. We classify such games according
to the information and the power of randomization available to the players. On
the basis of information, the game can be one-sided with either (a) player 1,
or (b) player 2 having partial observation (and the other player has perfect observation),
or two-sided with (c) both players having partial observation. On the basis of
randomization, the players (a) may not be allowed to use randomization (pure strategies),
or (b) may choose a probability distribution over actions but the actual random
choice is external and not visible to the player (actions invisible), or (c) may
use full randomization. Our main results for pure strategies are as follows. (1)
For one-sided games with player 1 having partial observation we show that (in
contrast to full randomized strategies) belief-based (subset-construction based)
strategies are not sufficient, and we present an exponential upper bound on memory
both for almostsure and positive winning strategies; we show that the problem
of deciding the existence of almost-sure and positive winning strategies for player
1 is EXPTIME-complete. (2) For one-sided games with player 2 having partial observation
we show that non-elementary memory is both necessary and sufficient for both almost-sure
and positive winning strategies. (3) We show that for the general (two-sided)
case finite-memory strategies are sufficient for both positive and almost-sure
winning, and at least non-elementary memory is required. We establish the equivalence
of the almost-sure winning problems for pure strategies and for randomized strategies
with actions invisible. Our equivalence result exhibits serious flaws in previous
results of the literature: we show a non-elementary memory lower bound for almost-sure
winning whereas an exponential upper bound was previously claimed.'

that use Boolean variables, and in addition, access a single read-only array whose
length is potentially unbounded, and whose elements range over an unbounded data
domain. We show that the reachability problem, while undecidable in general, is
(1) PSPACE-complete for programs in which the array-accessing for-loops are not
nested, (2) decidable for a restricted class of programs with doubly nested loops.
The second result establishes connections to automata and logics defining languages
over data words.

text: We solve the longstanding open problems of the blow-up involved in the translations,
when possible, of a nondeterministic Büchi word automaton (NBW) to a nondeterministic
co-Büchi word automaton (NCW) and to a deterministic co-Büchi word automaton (DCW).
For the NBW to NCW translation, the currently known upper bound is 2o(nlog n)
and the lower bound is 1.5n. We improve the upper bound to n2n and describe a
matching lower bound of 2ω(n). For the NBW to DCW translation, the currently known
upper bound is 2o(nlog n). We improve it to 2 o(n), which is asymptotically tight.
Both of our upper-bound constructions are based on a simple subset construction,
do not involve intermediate automata with richer acceptance conditions, and can
be implemented symbolically. We continue and solve the open problems of translating
nondeterministic Streett, Rabin, Muller, and parity word automata to NCW and to
DCW. Going via an intermediate NBW is not optimal and we describe direct, simple,
and asymptotically tight constructions, involving a 2o(n) blow-up. The constructions
are variants of the subset construction, providing a unified approach for translating
all common classes of automata to NCW and DCW. Beyond the theoretical importance
of the results, we point to numerous applications of the new constructions. In
particular, they imply a simple subset-construction based translation, when possible,
of LTL to deterministic Büchi word automata.

text: "Energy games belong to a class of turn-based two-player infinite-duration
games played on a weighted directed graph. It is one of the rare and intriguing
combinatorial problems that lie in NP ∩ co−NP, but are not known to be in P. While
the existence of polynomial-time algorithms has been a major open problem for
decades, there is no algorithm that solves any non-trivial subclass in polynomial
time.\r\nIn this paper, we give several results based on the weight structures
of the graph. First, we identify a notion of penalty and present a polynomial-time
algorithm when the penalty is large. Our algorithm is the first polynomial-time
algorithm on a large class of weighted graphs. It includes several counter examples
that show that many previous algorithms, such as value iteration and random facet
algorithms, require at least sub-exponential time. Our main technique is developing
the first non-trivial approximation algorithm and showing how to convert it to
an exact algorithm. Moreover, we show that in a practical case in verification
where weights are clustered around a constant number of values, the energy game
problem can be solved in polynomial time. We also show that the problem is still
as hard as in general when the clique-width is bounded or the graph is strongly
ergodic, suggesting that restricting graph structures need not help."

text: "Quantitative automata are nondeterministic finite automata with edge weights.
They value a\r\nrun by some function from the sequence of visited weights to the
reals, and value a word by its\r\nminimal/maximal run. They generalize boolean
automata, and have gained much attention in\r\nrecent years. Unfortunately, important
automaton classes, such as sum, discounted-sum, and\r\nlimit-average automata,
cannot be determinized. Yet, the quantitative setting provides the potential\r\nof
approximate determinization. We define approximate determinization with respect
to\r\na distance function, and investigate this potential.\r\nWe show that sum
automata cannot be determinized approximately with respect to any\r\ndistance
function. However, restricting to nonnegative weights allows for approximate determinization\r\nwith
respect to some distance functions.\r\nDiscounted-sum automata allow for approximate
determinization, as the influence of a word’s\r\nsuffix is decaying. However,
the naive approach, of unfolding the automaton computations up\r\nto a sufficient
level, is shown to be doubly exponential in the discount factor. We provide an\r\nalternative
construction that is singly exponential in the discount factor, in the precision,
and\r\nin the number of states. We prove matching lower bounds, showing exponential
dependency on\r\neach of these three parameters.\r\nAverage and limit-average
automata are shown to prohibit approximate determinization with\r\nrespect to
any distance function, and this is the case even for two weights, 0 and 1."
acknowledgement: We thank Laurent Doyen for great ideas and valuable help in analyzing
discounted-sum automata.
