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: The problem of the origin of metazoa is becoming more urgent in the context
of astrobiology. By now it is clear that clues to the understanding of this crucial
transition in the evolution of life can arise in a fourth pathway besides the
three possibilities in the quest for simplicity outlined by Bonner in his classical
book. In other words, solar system exploration seems to be one way in the long-term
to elucidate the simplicity of evolutionary development. We place these ideas
in the context of different inheritance systems, namely the genotypic and phenotypic
replicators with limited or unlimited heredity, and ask which of these can support
multicellular development, and to which degree of complexity. However, the quest
for evidence on the evolution of biotas from planets around other stars does not
seem to be feasible with present technology with direct visualization of living
organisms on exoplanets. But this may be attempted on the Galilean moons of Jupiter
where there is a possibility of detecting reliable biomarkers in the next decade
with the Europa Jupiter System Mission, in view of recent progress by landing
micropenetrators on planetary, or satellite surfaces. Mars is a second possibility
in the inner Solar System, in spite of the multiple difficulties faced by the
fleet of past, present and future missions. We discuss a series of preliminary
ideas for elucidating the origin of metazoan analogues with available instrumentation
in potential payloads of feasible space missions to the Galilean moons.

text: "We show a hardness-preserving construction of a PRF from any length doubling
PRG which improves upon known constructions whenever we can put a non-trivial
upper bound q on the number of queries to the PRF. Our construction requires only
O(logq) invocations to the underlying PRG with each query. In comparison, the
number of invocations by the best previous hardness-preserving construction (GGM
using Levin's trick) is logarithmic in the hardness of the PRG. For example, starting
from an exponentially secure PRG {0,1} n → {0,1} 2n, we get a PRF which is exponentially
secure if queried at most q = exp(√n)times and where each invocation of the PRF
requires Θ(√n) queries to the underlying PRG. This is much less than the Θ(n)
required by known constructions. \r\n"

text: 'The (decisional) learning with errors problem (LWE) asks to distinguish "noisy"
inner products of a secret vector with random vectors from uniform. The learning
parities with noise problem (LPN) is the special case where the elements of the
vectors are bits. In recent years, the LWE and LPN problems have found many applications
in cryptography. In this paper we introduce a (seemingly) much stronger adaptive
assumption, called "subspace LWE" (SLWE), where the adversary can learn
the inner product of the secret and random vectors after they were projected into
an adaptively and adversarially chosen subspace. We prove that, surprisingly,
the SLWE problem mapping into subspaces of dimension d is almost as hard as LWE
using secrets of length d (the other direction is trivial.) This result immediately
implies that several existing cryptosystems whose security is based on the hardness
of the LWE/LPN problems are provably secure in a much stronger sense than anticipated.
As an illustrative example we show that the standard way of using LPN for symmetric
CPA secure encryption is even secure against a very powerful class of related
key attacks. '

text: 'We consider the problem of amplifying the "lossiness" of functions.
We say that an oracle circuit C*: {0,1} m → {0,1}* amplifies relative lossiness
from ℓ/n to L/m if for every function f:{0,1} n → {0,1} n it holds that 1 If f
is injective then so is C f. 2 If f has image size of at most 2 n-ℓ, then C f
has image size at most 2 m-L. The question is whether such C* exists for L/m ≫
ℓ/n. This problem arises naturally in the context of cryptographic "lossy
functions," where the relative lossiness is the key parameter. We show that
for every circuit C* that makes at most t queries to f, the relative lossiness
of C f is at most L/m ≤ ℓ/n + O(log t)/n. In particular, no black-box method making
a polynomial t = poly(n) number of queries can amplify relative lossiness by more
than an O(logn)/n additive term. We show that this is tight by giving a simple
construction (cascading with some randomization) that achieves such amplification.'

text: 'Traditionally, symmetric-key message authentication codes (MACs) are easily
built from pseudorandom functions (PRFs). In this work we propose a wide variety
of other approaches to building efficient MACs, without going through a PRF first.
In particular, unlike deterministic PRF-based MACs, where each message has a unique
valid tag, we give a number of probabilistic MAC constructions from various other
primitives/assumptions. Our main results are summarized as follows: We show several
new probabilistic MAC constructions from a variety of general assumptions, including
CCA-secure encryption, Hash Proof Systems and key-homomorphic weak PRFs. By instantiating
these frameworks under concrete number theoretic assumptions, we get several schemes
which are more efficient than just using a state-of-the-art PRF instantiation
under the corresponding assumption. For probabilistic MACs, unlike deterministic
ones, unforgeability against a chosen message attack (uf-cma ) alone does not
imply security if the adversary can additionally make verification queries (uf-cmva
). We give an efficient generic transformation from any uf-cma secure MAC which
is "message-hiding" into a uf-cmva secure MAC. This resolves the main
open problem of Kiltz et al. from Eurocrypt''11; By using our transformation on
their constructions, we get the first efficient MACs from the LPN assumption.
While all our new MAC constructions immediately give efficient actively secure,
two-round symmetric-key identification schemes, we also show a very simple, three-round
actively secure identification protocol from any weak PRF. In particular, the
resulting protocol is much more efficient than the trivial approach of building
a regular PRF from a weak PRF. © 2012 International Association for Cryptologic

We study the complexity of valued constraint satisfaction problems (VCSP). A problem from VCSP is characterised by a constraint language, a fixed set of cost functions over a finite domain. An instance of the problem is specified by a sum of cost functions from the language and the goal is to minimise the sum. Under the unique games conjecture, the approximability of finite-valued VCSPs is well-understood, see Raghavendra [FOCS’08]. However, there is no characterisation of finite-valued VCSPs, let alone general-valued VCSPs, that can be solved exactly in polynomial time, thus giving insights from a combinatorial optimisation perspective.
We consider the case of languages containing all possible unary cost functions. In the case of languages consisting of only {0, ∞}-valued cost functions (i.e. relations), such languages have been called conservative and studied by Bulatov [LICS’03] and recently by Barto [LICS’11]. Since we study valued languages, we call a language conservative if it contains all finite-valued unary cost functions. The computational complexity of conservative valued languages has been studied by Cohen et al. [AIJ’06] for languages over Boolean domains, by Deineko et al. [JACM’08] for {0,1}-valued languages (a.k.a Max-CSP), and by Takhanov [STACS’10] for {0,∞}-valued languages containing all finite- valued unary cost functions (a.k.a. Min-Cost-Hom).
We prove a Schaefer-like dichotomy theorem for conservative valued languages: if all cost functions in the language satisfy a certain condition (specified by a complementary combination of STP and MJN multimorphisms), then any instance can be solved in polynomial time (via a new algorithm developed in this paper), otherwise the language is NP-hard. This is the first complete complexity classification of general-valued constraint languages over non-Boolean domains. It is a common phenomenon that complexity classifications of problems over non-Boolean domains is significantly harder than the Boolean case. The polynomial-time algorithm we present for the tractable cases is a generalisation of the submodular minimisation problem and a result of Cohen et al. [TCS’08].
Our results generalise previous results by Takhanov [STACS’10] and (a subset of results) by Cohen et al. [AIJ’06] and Deineko et al. [JACM’08]. Moreover, our results do not rely on any computer-assisted search as in Deineko et al. [JACM’08], and provide a powerful tool for proving hardness of finite-valued and general-valued languages.

text: "Viral manipulation of transduction pathways associated with key cellular
functions such as survival, response to microbial infection, and cytoskeleton
reorganization can provide the supportive milieu for a productive infection. Here,
we demonstrate that vaccinia virus (VACV) infection leads to activation of the
stress-activated protein kinase (SAPK)/extracellular signal-regulated kinase (ERK)
4/7 (MKK4/7)-c-Jun N-terminal protein kinase 1/2 (JNK1/2) pathway; further, the
stimulation of this pathway requires postpenetration, prereplicative events in
the viral replication cycle. Although the formation of intracellular mature virus
(IMV) was not affected in MKK4/7- or JNK1/2-knockout (KO) cells, we did note an
accentuated deregulation of microtubule and actin network organization in infected
JNK1/2-KO cells. This was followed by deregulated viral trafficking to the periphery
and enhanced enveloped particle release. Furthermore, VACV infection induced alterations
in the cell contractility and morphology, and cell migration was reduced in the
JNK-KO cells. In addition, phosphorylation of proteins implicated with early cell
contractility and cell migration, such as microtubule-associated protein 1B and
paxillin, respectively, was not detected in the VACV-infected KO cells. In sum,
our findings uncover a regulatory role played by the MKK4/7-JNK1/2 pathway in
cytoskeleton reorganization during VACV infection.\r\n"

text: 'A procedure for the continuous production of Cu 2ZnSnS 4 (CZTS) nanoparticles
with controlled composition is presented. CZTS nanoparticles were prepared through
the reaction of the metals'' amino complexes with elemental sulfur in a continuous-flow
reactor at moderate temperatures (300-330 °C). High-resolution transmission electron
microscopy and X-ray diffraction analysis showed the nanocrystals to have a crystallographic
structure compatible with that of the kesterite. Chemical characterization of
the materials showed the presence of the four elements in each individual nanocrystal.
Composition control was achieved by adjusting the solution flow rate through the
reactor and the proper choice of the nominal precursor concentration within the
flowing solution. Single-particle analysis revealed a composition distribution
within each sample, which was optimized at the highest synthesis temperatures
used. '

text: The theory of persistent homology opens up the possibility to reason about
topological features of a space or a function quantitatively and in combinatorial
terms. We refer to this new angle at a classical subject within algebraic topology
as a point calculus, which we present for the family of interlevel sets of a real-valued
function. Our account of the subject is expository, devoid of proofs, and written
for non-experts in algebraic topology.

text: We introduce two-level discounted and mean-payoff games played by two players
on a perfect-information stochastic game graph. The upper level game is a discounted
or mean-payoff game and the lower level game is a (undiscounted) reachability
game. Two-level games model hierarchical and sequential decision making under
uncertainty across different time scales. For both discounted and mean-payoff
two-level games, we show the existence of pure memoryless optimal strategies for
both players and an ordered field property. We show that if there is only one
player (Markov decision processes), then the values can be computed in polynomial
time. It follows that whether the value of a player is equal to a given rational
constant in two-level discounted or mean-payoff games can be decided in NP ∩ coNP.
We also give an alternate strategy improvement algorithm to compute the value.

text: The physical distance between presynaptic Ca2+ channels and the Ca2+ sensors
that trigger exocytosis of neurotransmitter-containing vesicles is a key determinant
of the signalling properties of synapses in the nervous system. Recent functional
analysis indicates that in some fast central synapses, transmitter release is
triggered by a small number of Ca2+ channels that are coupled to Ca2+ sensors
at the nanometre scale. Molecular analysis suggests that this tight coupling is
generated by protein–protein interactions involving Ca2+ channels, Ca2+ sensors
and various other synaptic proteins. Nanodomain coupling has several functional
advantages, as it increases the efficacy, speed and energy efficiency of synaptic
transmission.

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 a finite state space for
an infinite number of rounds. The games are concurrent: in each round, the two
players (player 1 and player 2) choose their moves independently and simultaneously;
the current state and the two moves determine a probability distribution over
the successor states. We also consider the important special case of turn-based
stochastic games where players make moves in turns, rather than concurrently.
We study concurrent games with \omega-regular winning conditions specified as
parity objectives. The value for player 1 for a parity objective is the maximal
probability with which the player can guarantee the satisfaction of the objective
against all strategies of the opponent. We study the problem of continuity and
robustness of the value function in concurrent and turn-based stochastic parity
gameswith respect to imprecision in the transition probabilities. We present quantitative
bounds on the difference of the value function (in terms of the imprecision of
the transition probabilities) and show the value continuity for structurally equivalent
concurrent games (two games are structurally equivalent if the support of the
transition function is same and the probabilities differ). We also show robustness
of optimal strategies for structurally equivalent turn-based stochastic parity
games. Finally we show that the value continuity property breaks without the structurally
equivalent assumption (even for Markov chains) and show that our quantitative
bound is asymptotically optimal. Hence our results are tight (the assumption is
both necessary and sufficient) and optimal (our quantitative bound is asymptotically
optimal).'

text: The goal of this work is to study the superconducting coherence length in
the fluctuation regime in cuprate superconductors. In this work we present cantilever
torque magnetometry measurements of micron-size BSCCO flakes patterned with arrays
of nanometer scale rings or holes. Using ultrasensitive dynamic torque magnetometry,
oscillations in magnetization are observed near Tc as a function of the applied
magnetic flux threading the array. Special effort was made to detect the oscillations
in magnetization at temperatures above Tc, where the Nernst effect and magnetization
measurements suggest the possibility of pairing. To constrain the magnitude of
the coherence length in the fluctuation regime, we will present the dependence
of the amplitude of the h/2e period oscillations as a function of temperature
and hole size.

text: Under physiological conditions the brain, via the purine salvage pathway,
reuses the preformed purine bases hypoxanthine, derived from ATP degradation,
and adenine (Ade), derived from polyamine synthesis, to restore its ATP pool.
However, the massive degradation of ATP during ischemia, although providing valuable
neuroprotective adenosine, results in the accumulation and loss of diffusible
purine metabolites and thereby leads to a protracted reduction in the post-ischemic
ATP pool size. In vivo, this may both limit the ability to deploy ATP-dependent
reparative mechanisms and reduce the subsequent availability of adenosine, whilst
in brain slices results in tissue with substantially lower levels of ATP than
in vivo. In the present review, we describe the mechanisms by which brain tissue
replenishes its ATP, how this can be improved with the clinically tolerated chemicals
D-ribose and adenine, and the functional, and potential therapeutic, implications
of doing so.

text: We propose a logic-based framework for automated reasoning about sequential
programs manipulating singly-linked lists and arrays with unbounded data. We introduce
the logic SLAD, which allows combining shape constraints, written in a fragment
of Separation Logic, with data and size constraints. We address the problem of
checking the entailment between SLAD formulas, which is crucial in performing
pre-post condition reasoning. Although this problem is undecidable in general
for SLAD, we propose a sound and powerful procedure that is able to solve this
problem for a large class of formulas, beyond the capabilities of existing techniques
and tools. We prove that this procedure is complete, i.e., it is actually a decision
procedure for this problem, for an important fragment of SLAD including known
decidable logics. We implemented this procedure and shown its preciseness and
its efficiency on a significant benchmark of formulas.

text: Multi-dimensional mean-payoff and energy games provide the mathematical foundation
for the quantitative study of reactive systems, and play a central role in the
emerging quantitative theory of verification and synthesis. In this work, we study
the strategy synthesis problem for games with such multi-dimensional objectives
along with a parity condition, a canonical way to express ω-regular conditions.
While in general, the winning strategies in such games may require infinite memory,
for synthesis the most relevant problem is the construction of a finite-memory
winning strategy (if one exists). Our main contributions are as follows. First,
we show a tight exponential bound (matching upper and lower bounds) on the memory
required for finite-memory winning strategies in both multi-dimensional mean-payoff
and energy games along with parity objectives. This significantly improves the
triple exponential upper bound for multi energy games (without parity) that could
be derived from results in literature for games on VASS (vector addition systems
with states). Second, we present an optimal symbolic and incremental algorithm
to compute a finite-memory winning strategy (if one exists) in such games. Finally,
we give a complete characterization of when finite memory of strategies can be
traded off for randomness. In particular, we show that for one-dimension mean-payoff
parity games, randomized memoryless strategies are as powerful as their pure finite-memory
counterparts.

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."
