text: Let Q be a non-singular diagonal quadratic form in at least four variables.
We provide upper bounds for the number of integer solutions to the equation Q
= 0, which lie in a box with sides of length 2B, as B → ∞. The estimates obtained
are completely uniform in the coefficients of the form, and become sharper as
they grow larger in modulus.

text: It was recently shown by Hansen that the Wigner-Yanase entropy is, for general
states of quantum systems, not subadditive with respect to decomposition into
two subsystems, although this property is known to hold for pure states. We investigate
the question whether the weaker property of subadditivity for pure states with
respect to decomposition into more than two subsystems holds. This property would
have interesting applications in quantum chemistry. We show, however, that it
does not hold in general, and provide a counterexample.

text: After recalling briefly the connection between spontaneous symmetry breaking
and off-diagonal long-range order for models of magnets a general proof of spontaneous
breaking of gauge symmetry as a consequence of Bose-Einstein condensation is presented.
The proof is based on a rigorous validation of Bogoliubov's c-number substitution
for the k = 0 mode operator α0.

text: The increasing interest in the Müller density-matrix-functional theory has
led us to a systematic mathematical investigation of its properties. This functional
is similar to the Hartree-Fock (HF) functional, but with a modified exchange term
in which the square of the density matrix γ(x, x′) is replaced by the square of
γ1 2 (x, x′). After an extensive introductory discussion of density-matrix-functional
theory we show, among other things, that this functional is convex (unlike the
HF functional) and that energy minimizing γ 's have unique densities ρ(r), which
is a physically desirable property often absent in HF theory. We show that minimizers
exist if N≤Z, and derive various properties of the minimal energy and the corresponding
minimizers. We also give a precise statement about the equation for the orbitals
of γ, which is more complex than for HF theory. We state some open mathematical
questions about the theory together with conjectured solutions.

text: The main factors for reducing the consumption of a vehicle are reduction of
curb weight, air drag and increase in the drivetrain efficiency. Highly efficient
drivetrains can be developed based on PEFC technology and curb weight may be limited
by an innovative vehicle construction. In this paper, data on consumption and
efficiency of a four‐place passenger vehicle with a curb weight of 850 kg and
an H2/O2 fed PEFC/Supercap hybrid electric powertrain are presented. Hydrogen
consumption in the New European Driving Cycle is 0.67 kg H2/100 km, which corresponds
to a gasoline equivalent consumption of 2.5 l/100 km. When including the energy
needed to supply pure oxygen, the calculated consumption increases from 0.67 to
0.69–0.79 kg H2/100 km, depending on the method of oxygen production.

text: Efficiency is the key parameter for the application of fuel cells in automotive
applications. The efficiency of a hydrogen/oxygen polymer electrolyte fuel cell
system is analyzed and compared to hydrogen/air systems. The analysis is performed
for the tank to electric power chain. Furthermore, the additional energy required
for using pure oxygen as a second fuel is analyzed and included in the calculation.
The results show that if hydrogen is produced from primary fossil energy carriers,
such as natural gas and pure oxygen needs to be obtained by a conventional process;
the fuel to electric current efficiency is comparable for hydrogen/oxygen and
hydrogen/air systems. However, if hydrogen and oxygen are produced by the splitting
of water, i.e., by electrolysis or by a thermochemical process, the fuel to electric
current efficiency for the hydrogen/oxygen system is clearly superior.

text: Our experimental results shown here disprove that finite diffusion can generally
be assumed in ac impedance models for H2/air-polymer electrolyte fuel cells (PEFCs)
to account for the diffusive transport of oxygen through the gas diffusion layer
(GDL) toward the air electrode. It is shown that the amplitude of the oxygen concentration
oscillation created as a consequence of superimposed ac current at the air electrode
is not zero at the channel/GDL interface but extends into the gas channels, at
least below modulation frequencies of fmod=10 Hz . By this, sinusoidal oxygen-concentration
oscillations within the cathode gas channels are excited locally along the flow
field. Due to the forced air convection in the cathode flow-field channels, a
coupling via the gas phase occurs downstream of the flow field. The coupling strongly
affects the local and by this the overall impedance response of the cell and evokes
the formation of a low-frequency arc in H2/air-PEFC impedance spectra. Based on
the experimental results, a qualitative model is presented explaining the local
impedance response of a segmented 200cm2H2/air PEFC.

text: Gradients of axon guidance molecules instruct the formation of continuous
neural maps, such as the retinotopic map in the vertebrate visual system. Here
we show that molecular gradients can also instruct the formation of a discrete
neural map. In the fly olfactory system, axons of 50 classes of olfactory receptor
neurons (ORNs) and dendrites of 50 classes of projection neurons (PNs) form one-to-one
connections at discrete units called glomeruli. We provide expression, loss- and
gain-of-function data to demonstrate that the levels of transmembrane Semaphorin-1a
(Sema-1a), acting cell-autonomously as a receptor or part of a receptor complex,
direct the dendritic targeting of PNs along the dorsolateral to ventromedial axis
of the antennal lobe. Sema-1a also regulates PN axon targeting in higher olfactory
centers. Thus, graded expression of Sema-1a contributes to connection specificity
from ORNs to PNs and then to higher brain centers, ensuring proper representation
of olfactory information in the brain.

text: Axon-axon interactions have been implicated in neural circuit assembly, but
the underlying mechanisms are poorly understood. Here, we show that in the Drosophila
antennal lobe, early-arriving axons of olfactory receptor neurons (ORNs) from
the antenna are required for the proper targeting of late-arriving ORN axons from
the maxillary palp (MP). Semaphorin-1a is required for targeting of all MP but
only half of the antennal ORN classes examined. Sema-1a acts nonautonomously to
control ORN axon-axon interactions, in contrast to its cell-autonomous function
in olfactory projection neurons. Phenotypic and genetic interaction analyses implicate
PlexinA as the Sema-1a receptor in ORN targeting. Sema-1a on antennal ORN axons
is required for correct targeting of MP axons within the antennal lobe, while
interactions amongst MP axons facilitate their entry into the antennal lobe. We
propose that Sema-1a/PlexinA-mediated repulsion provides a mechanism by which
early-arriving ORN axons constrain the target choices of late-arriving axons.

text: 'In many species, females show reduced expression of a trait that is under
sexual selection in males, and this expression is thought to be maintained through
genetic associations with the male phenotype. However, there is also the potential
for the female trait to convey an advantage in intrasexual conflicts over resources.
We tested this hypothesis in a feral population of Soay sheep, in which males
and females have a polymorphism for horn development, producing either full (normal
horned), reduced (scurred) or no (polled, females only) horns. During the lambing
period, females who possessed horns were more likely to initiate and win aggressive
interactions, independent of age, weight and birthing status. The occurrence of
aggression was also context dependent, decreasing over the lambing period and
associated with local density. Our results demonstrate that a trait that confers
benefits to males during intrasexual competition for mates may also be used by
females in intrasexual competition over resources: males use weaponry to gain
mates, whereas females use weaponry to gain food.'

We study games played on graphs with omega-regular conditions specified as parity, Rabin, Streett or Muller conditions. These games have applications in the verification, synthesis, modeling, testing, and compatibility checking of reactive systems. Important distinctions between graph games are as follows: (a) turn-based vs. concurrent games, depending on whether at a state of the game only a single player makes a move, or players make moves simultaneously; (b) deterministic vs. stochastic, depending on whether the transition function is a deterministic or a probabilistic function over successor states; and (c) zero-sum vs. non-zero-sum, depending on whether the objectives of the players are strictly conflicting or not.
We establish that the decision problem for turn-based stochastic zero-sum games with Rabin, Streett, and Muller objectives are NP-complete, coNP-complete, and PSPACE-complete, respectively, substantially improving the previously known 3EXPTIME bound. We also present strategy improvement style algorithms for turn-based stochastic Rabin and Streett games. In the case of concurrent stochastic zero-sum games with parity objectives we obtain a PSPACE bound, again improving the previously known 3EXPTIME bound. As a consequence, concurrent stochastic zero-sum games with Rabin, Streett, and Muller objectives can be solved in EXPSPACE, improving the previously known 4EXPTIME bound. We also present an elementary and combinatorial proof of the existence of memoryless \epsilon-optimal strategies in concurrent stochastic games with reachability objectives, for all real \epsilon>0, where an \epsilon-optimal strategy achieves the value of the game with in \epsilon against all strategies of the opponent. We also use the proof techniques to present a strategy improvement style algorithm for concurrent stochastic reachability games.
We then go beyond \omega-regular objectives and study the complexity of an important class of quantitative objectives, namely, limit-average objectives. In the case of limit-average games, the states of the graph is labeled with rewards and the goal is to maximize the long-run average of the rewards. We show that concurrent stochastic zero-sum games with limit-average objectives can be solved in EXPTIME.
Finally, we introduce a new notion of equilibrium, called secure equilibrium, in non-zero-sum games which captures the notion of conditional competitiveness. We prove the existence of unique maximal secure equilibrium payoff profiles in turn-based deterministic games, and present algorithms to compute such payoff profiles. We also show how the notion of secure equilibrium extends the assume-guarantee style of reasoning in the game theoretic framework.

text: "Complex system design today calls for compositional design and implementation.
However each component is designed with certain assumptions about the environment
it is meant to operate in, and delivering certain guarantees if those assumptions
are satisfied; numerous inter-component interaction errors are introduced in the
manual and error-prone integration process as there is little support in design
environments for machine-readably representing these assumptions and guarantees
and automatically checking consistency during integration.\r\n\r\nBased on Interface
Automata we propose a framework for compositional design and analysis of systems:
a set of domain-specific automata-theoretic type systems for compositional system
specification and analysis by behavioral specification of open systems. We focus
on three different domains: component-based hardware systems communicating on
bidirectional wires. concurrent distributed recursive message-passing software
systems, and embedded software system components operating in resource-constrained
environments. For these domains we present approaches to formally represent the
assumptions and conditional guarantees between interacting open system components.
Composition of such components produces new components with the appropriate assumptions
and guarantees. We check satisfaction of temporal logic specifications by such
components, and the substitutability of one component with another in an arbitrary
context. Using this framework one can analyze large systems incrementally without
needing extensive summary information to close the system at each stage. Furthermore,
we focus only on the inter-component interaction behavior without dealing with
the full implementation details of each component. Many of the merits of automata-theoretic
model-checking are combined with the compositionality afforded by type-system
based techniques. We also present an integer-based extension of the conventional
boolean verification framework motivated by our interface formalism for embedded
software components.\r\n\r\nOur algorithms for checking the behavioral compatibility
of component interfaces are available in our tool Chic, which can be used as a
plug-in for the Java IDE JBuilder and the heterogenous modeling and design environment
Ptolemy II.\r\n\r\nFinally, we address the complementary problem of partitioning
a large system into meaningful coherent components by analyzing the interaction
patterns between its basic elements. We demonstrate the usefulness of our partitioning
approach by evaluating its efficacy in improving unit-test branch coverage for
a large software system implemented in C."

text: BLAST is an automatic verification tool for checking temporal safety properties
of C programs. Given a C program and a temporal safety property, BLAST either
statically proves that the program satisfies the safety property, or provides
an execution path that exhibits a violation of the property (or, since the problem
is undecidable, does not terminate). BLAST constructs, explores, and refines abstractions
of the program state space based on lazy predicate abstraction and interpolation-based
predicate discovery. This paper gives an introduction to BLAST and demonstrates,
through two case studies, how it can be applied to program verification and test-case
generation. In the first case study, we use BLAST to statically prove memory safety
for C programs. We use CCured, a type-based memory-safety analyzer, to annotate
a program with run-time assertions that check for safe memory operations. Then,
we use BLAST to remove as many of the run-time checks as possible (by proving
that these checks never fail), and to generate execution scenarios that violate
the assertions for the remaining run-time checks. In our second case study, we
use BLAST to automatically generate test suites that guarantee full coverage with
respect to a given predicate. Given a C program and a target predicate p, BLAST
determines the program locations q for which there exists a program execution
that reaches q with p true, and automatically generates a set of test vectors
that cause such executions. Our experiments show that BLAST can provide automated,
precise, and scalable analysis for C programs.

text: We consider the minimum-time reachability problem in concurrent two-player
timed automaton game structures. We show how to compute the minimum time needed
by a player to reach a target location against all possible choices of the opponent.
We do not put any syntactic restriction on the game structure, nor do we require
any player to guarantee time divergence. We only require players to use receptive
strategies which do not block time. The minimal time is computed in part using
a fixpoint expression, which we show can be evaluated on equivalence classes of
a non-trivial extension of the clock-region equivalence relation for timed automata.

text: The success of software verification depends on the ability to find a suitable
abstraction of a program automatically. We propose a method for automated abstraction
refinement which overcomes some limitations of current predicate discovery schemes.
In current schemes, the cause of a false alarm is identified as an infeasible
error path, and the abstraction is refined in order to remove that path. By contrast,
we view the cause of a false alarm -the spurious counterexample- as a full-fledged
program, namely, a fragment of the original program whose control-flow graph may
contain loops and represent unbounded computations. There are two advantages to
using such path programs as counterexamples for abstraction refinement. First,
we can bring the whole machinery of program analysis to bear on path programs,
which are typically small compared to the original program. Specifically, we use
constraint-based invariant generation to automatically infer invariants of path
programs-so-called path invariants. Second, we use path invariants for abstraction
refinement in order to remove not one infeasibility at a time, but at once all
(possibly infinitely many) infeasible error computations that are represented
by a path program. Unlike previous predicate discovery schemes, our method handles
loops without unrolling them; it infers abstractions that involve universal quantification
and naturally incorporates disjunctive reasoning.
