text: 'Anopheles darlingi is the primary malaria vector in Latin America, and is
especially important in Amazonian Brazil. Historically, control efforts have been
focused on indoor house spraying using a variety of insecticides, but since the
mid-1990s there has been a shift to patient treatment and focal insecticide fogging.
Anopheles darlingi was believed to have been significantly reduced in a gold-mining
community, Peixoto de Azevedo (in Mato Grosso State), in the early 1990s by insecticide
use during a severe malaria epidemic. In contrast, although An. darlingi was eradicated
from some districts of the city of Belem (the capital of Para State) in 1968 to
reduce malaria, populations around the water protection area in the eastern district
were treated only briefly. To investigate the population structure of An. darlingi
including evidence for a population bottleneck in Peixoto, we analyzed eight microsatellite
loci of 256 individuals from seven locations in Brazil: three in Amapa State,
three in Para State, and one in Mato Grosso State. Allelic diversity and mean
expected heterozygosity were high for all populations (mean number alleles/locus
and H(E) were 13.5 and 0.834, respectively) and did not differ significantly between
locations. Significant heterozygote deficits were associated with linkage disequilibrium,
most likely due to either the Wahlund effect or selection. We found no evidence
for a population bottleneck in Peixoto, possibly because the reduction was not
extreme enough to be detected. Overall estimates of long-term N(e) varied from
92.4 individuals under the linkage disequilibrium model to infinity under the
heterozygote excess model. Fixation indices and analysis of molecular variance
demonstrated significant differentiation between locations north and south of
the Amazon River, suggesting a degree of genetic isolation between them, attributed
to isolation by distance.'

text: We propose and evaluate a new algorithm for checking the universality of nondeterministic
finite automata. In contrast to the standard algorithm, which uses the subset
construction to explicitly determinize the automaton, we keep the determinization
step implicit. Our algorithm computes the least fixed point of a monotone function
on the lattice of antichains of state sets. We evaluate the performance of our
algorithm experimentally using the random automaton model recently proposed by
Tabakov and Vardi. We show that on the difficult instances of this probabilistic
model, the antichain algorithm outperforms the standard one by several orders
of magnitude. We also show how variations of the antichain method can be used
for solving the language-inclusion problem for nondeterministic finite automata,
and the emptiness problem for alternating finite automata.

text: 'We summarize some current trends in embedded systems design and point out
some of their characteristics, such as the chasm between analytical and computational

We call for a coherent scientific foundation for embedded systems design, and
we discuss a few key demands on such a foundation: the need for encompassing several
manifestations of heterogeneity, and the need for constructivity in design. We
believe that the development of a satisfactory Embedded Systems Design Science

text: We add freeze quantifiers to the game logic ATL in order to specify real-time
objectives for games played on timed structures. We define the semantics of the
resulting logic TATL by restricting the players to physically meaningful strategies,
which do not prevent time from diverging. We show that TATL can be model checked
over timed automaton games. We also specify timed optimization problems for physically
meaningful strategies, and we show that for timed automaton games, the optimal
answers can be approximated to within any degree of precision.

text: We present an assume-guarantee interface algebra for real-time components.
In our formalism a component implements a set of task sequences that share a resource.
A component interface consists of an arrival rate function and a latency for each
task sequence, and a capacity function for the shared resource. The interface
specifies that the component guarantees certain task latencies depending on assumptions
about task arrival rates and allocated resource capacities. Our algebra defines
compatibility and refinement relations on interfaces. Interface compatibility
can be checked on partial designs, even when some component interfaces are yet
unknown. In this case interface composition computes as new assumptions the weakest
constraints on the unknown components that are necessary to satisfy the specified
guarantees. Interface refinement is defined in a way that ensures that compatible
interfaces can be refined and implemented independently. Our algebra thus formalizes
an interface-based design methodology that supports both the incremental addition
of new components and the independent stepwise refinement of existing components.
We demonstrate the flexibility and efficiency of the framework through simulation
experiments.

text: The synthesis of reactive systems requires the solution of two-player games
on graphs with ω-regular objectives. When the objective is specified by a linear
temporal logic formula or nondeterministic Büchi automaton, then previous algorithms
for solving the game require the construction of an equivalent deterministic automaton.
However, determinization for automata on infinite words is extremely complicated,
and current implementations fail to produce deterministic automata even for relatively
small inputs. We show how to construct, from a given nondeterministic Büchi automaton,
an equivalent nondeterministic parity automaton that is good for solving games
with objective . The main insight is that a nondeterministic automaton is good
for solving games if it fairly simulates the equivalent deterministic automaton.
In this way, we omit the determinization step in game solving and reactive synthesis.
The fact that our automata are nondeterministic makes them surprisingly simple,
amenable to symbolic implementation, and allows an incremental search for winning
strategies.

text: One source of complexity in the μ-calculus is its ability to specify an unbounded
number of switches between universal (AX) and existential (EX) branching modes.
We therefore study the problems of satisfiability, validity, model checking, and
implication for the universal and existential fragments of the μ-calculus, in
which only one branching mode is allowed. The universal fragment is rich enough
to express most specifications of interest, and therefore improved algorithms
are of practical importance. We show that while the satisfiability and validity
problems become indeed simpler for the existential and universal fragments, this
is, unfortunately, not the case for model checking and implication. We also show
the corresponding results for the alternation-free fragment of the μ-calculus,
where no alternations between least and greatest fixed points are allowed. Our
results imply that efforts to find a polynomial-time model-checking algorithm
for the μ-calculus can be replaced by efforts to find such an algorithm for the
universal or existential fragment.

text: We consider the problem if a given program satisfies a specified safety property.
Interesting programs have infinite state spaces, with inputs ranging over infinite
domains, and for these programs the property checking problem is undecidable.
Two broad approaches to property checking are testing and verification. Testing
tries to find inputs and executions which demonstrate violations of the property.
Verification tries to construct a formal proof which shows that all executions
of the program satisfy the property. Testing works best when errors are easy to
find, but it is often difficult to achieve sufficient coverage for correct programs.
On the other hand, verification methods are most successful when proofs are easy
to find, but they are often inefficient at discovering errors. We propose a new
algorithm, Synergy, which combines testing and verification. Synergy unifies several
ideas from the literature, including counterexample-guided model checking, directed
testing, and partition refinement.This paper presents a description of the Synergy
algorithm, its theoretical properties, a comparison with related algorithms, and
a prototype implementation called Yogi.

text: 'We designed and implemented a new programming language called Hierarchical
Timing Language (HTL) for hard realtime systems. Critical timing constraints are
specified within the language,and ensured by the compiler. Programs in HTL are
extensible in two dimensions without changing their timing behavior: new program
modules can be added, and individual program tasks can be refined. The mechanism
supporting time invariance under parallel composition is that different program
modules communicate at specified instances of time. Time invariance under refinement
is achieved by conservative scheduling of the top level. HTL is a coordination
language, in that individual tasks can be implemented in "foreign" languages.
As a case study, we present a distributed HTL implementation of an automotive
steer-by-wire controller.'

text: Computational modeling of biological systems is becoming increasingly common
as scientists attempt to understand biological phenomena in their full complexity.
Here we distinguish between two types of biological models mathematical and computational
- according to their different representations of biological phenomena and their
diverse potential. We call the approach of constructing computational models of
biological systems executable biology, as it focuses on the design of executable
computer algorithms that mimic biological phenomena. We give an overview of the
main modeling efforts in this direction, and discuss some of the new challenges
that executable biology poses for computer science and biology. We argue that
for executable biology to reach its full potential as a mainstream biological
technique, formal and algorithmic approaches must be integrated into biological
research, driving biology towards a more precise engineering discipline.

text: A stochastic graph game is played by two players on a game graph with probabilistic
transitions. We consider stochastic graph games with ω-regular winning conditions
specified as parity objectives. These games lie in NP ∩ coNP. We present a strategy
improvement algorithm for stochastic parity games; this is the first non-brute-force
algorithm for solving these games. From the strategy improvement algorithm we
obtain a randomized subexponential-time algorithm to solve such games.

text: Games on graphs with ω-regular objectives provide a model for the control
and synthesis of reactive systems. Every ω-regular objective can be decomposed
into a safety part and a liveness part. The liveness part ensures that something
good happens “eventually.” Two main strengths of the classical, infinite-limit
formulation of liveness are robustness (independence from the granularity of transitions)
and simplicity (abstraction of complicated time bounds). However, the classical
liveness formulation suffers from the drawback that the time until something good
happens may be unbounded. A stronger formulation of liveness, so-called finitary
liveness, overcomes this drawback, while still retaining robustness and simplicity.
Finitary liveness requires that there exists an unknown, fixed bound b such that
something good happens within b transitions. While for one-shot liveness (reachability)
objectives, classical and finitary liveness coincide, for repeated liveness (Büchi)
objectives, the finitary formulation is strictly stronger. In this work we study
games with finitary parity and Streett (fairness) objectives. We prove the determinacy
of these games, present algorithms for solving these games, and characterize the
memory requirements of winning strategies. Our algorithms can be used, for example,
for synthesizing controllers that do not let the response time of a system increase
without bound.

text: We present a compositional theory of system verification, where specifications
assign real-numbered costs to systems. These costs can express a wide variety
of quantitative system properties, such as resource consumption, price, or a measure
of how well a system satisfies its specification. The theory supports the composition
of systems and specifications, and the hiding of variables. Boolean refinement
relations are replaced by real-numbered distances between descriptions of a system
at different levels of detail. We show that the classical Boolean rules for compositional
reasoning have quantitative counterparts in our setting. While our general theory
allows costs to be specified by arbitrary cost functions, we also consider a class
of linear cost functions, which give rise to an instance of our framework where
all operations are computable in polynomial time.

text: 'In 2-player non-zero-sum games, Nash equilibria capture the options for rational
behavior if each player attempts to maximize her payoff. In contrast to classical
game theory, we consider lexicographic objectives: first, each player tries to
maximize her own payoff, and then, the player tries to minimize the opponent''s
payoff. Such objectives arise naturally in the verification of systems with multiple
components. There, instead of proving that each component satisfies its specification
no matter how the other components behave, it sometimes suffices to prove that
each component satisfies its specification provided that the other components
satisfy their specifications. We say that a Nash equilibrium is secure if it is
an equilibrium with respect to the lexicographic objectives of both players. We
prove that in graph games with Borel winning conditions, which include the games
that arise in verification, there may be several Nash equilibria, but there is
always a unique maximal payoff profile of a secure equilibrium. We show how this
equilibrium can be computed in the case of ω-regular winning conditions, and we
characterize the memory requirements of strategies that achieve the equilibrium.'

text: "We consider Markov decision processes (MDPs) with multiple discounted reward
objectives. Such MDPs occur in design problems where one wishes to simultaneously
optimize several criteria, for example, latency and power. The possible trade-offs
between the different objectives are characterized by the Pareto curve. We show
that every Pareto-optimal point can be achieved by a memoryless strategy; however,
unlike in the single-objective case, the memoryless strategy may require randomization.
Moreover, we show that the Pareto curve can be approximated in polynomial time
in the size of the MDP. Additionally, we study the problem if a given value vector
is realizable by any strategy, and show that it can be decided in polynomial time;
but the question whether it is realizable by a deterministic memoryless strategy
is NP-complete. These results provide efficient algorithms for design exploration
in MDP models with multiple objectives.\nThis research was supported in part by

text: 'A concurrent reachability game is a two-player game played on a graph: at
each state, the players simultaneously and independently select moves; the two
moves determine jointly a probability distribution over the successor states.
The objective for player 1 consists in reaching a set of target states; the objective
for player 2 is to prevent this, so that the game is zero-sum. Our contributions
are two-fold. First, we present a simple proof of the fact that in concurrent
reachability games, for all epsilon > 0, memoryless epsilon-optimal strategies
exist. A memoryless strategy is independent of the history of plays, and an epsilon-optimal
strategy achieves the objective with probability within epsilon of the value of
the game. In contrast to previous proofs of this fact, which rely on the limit
behavior of discounted games using advanced Puisieux series analysis, our proof
is elementary and combinatorial. Second, we present a strategy-improvement (a.k.a.
policy-iteration) algorithm for concurrent games with reachability objectives.'
