text: 'A modular program analysis considers components independently and provides
a succinct summary for each component, which is used when checking the rest of
the system. Consider a system consisting of a library and a client. A temporal
summary, or interface, of the library specifies legal sequences of library calls.
The interface is safe if no call sequence violates the library''s internal invariants;
the interface is permissive if it contains every such sequence. Modular program
analysis requires full interfaces, which are both safe and permissive: the client
does not cause errors in the library if and only if it makes only sequences of
library calls that are allowed by the full interface of the library.Previous interface-based
methods have focused on safe interfaces, which may be too restrictive and thus
reject good clients. We present an algorithm for automatically synthesizing software
interfaces that are both safe and permissive. The algorithm generates interfaces
as graphs whose vertices are labeled with predicates over the library''s internal
state, and whose edges are labeled with library calls. The interface state is
refined incrementally until the full interface is constructed. In other words,
the algorithm automatically synthesizes a typestate system for the library, against
which any client can be checked for compatibility. We present an implementation
of the algorithm which is based on the BLAST model checker, and we evaluate some
case studies.'

text: We present a compositional approach to the implementation of hard real-time
software running on a distributed platform. We explain how several code suppliers,
coordinated by a system integrator, can independently generate different parts
of the distributed software. The task structure, interaction, and timing is specified
as a Giotto program. Each supplier is given a part of the Giotto program and a
timing interface, from which the supplier generates task and scheduling code.
The integrator then checks, individually for each supplier, in pseudo-polynomial
time, if the supplied code meets its timing specification. If all checks succeed,
then the supplied software parts are guaranteed to work together and implement
the original Giotto program. The feasibility of the approach is demonstrated by
a prototype implementation.

Much recent research has focused on the applications of games with ω-regular objectives in the control and verification of reactive systems. However, many of the game-based models are ill-suited for these applications, because they assume that each player has complete information about the state of the system (they are “perfect-information” games). This is because in many situations, a controller does not see the private state of the plant. Such scenarios are naturally modeled by “partial-information” games. On the other hand, these games are intractable; for example, partial-information games with simple reachability objectives are 2EXPTIME-complete.
We study the intermediate case of “semiperfect-information” games, where one player has complete knowledge of the state, while the other player has only partial knowledge. This model is appropriate in control situations where a controller must cope with plant behavior that is as adversarial as possible, i.e., the controller has partial information while the plant has perfect information. As is customary, we assume that the controller and plant take turns to make moves. We show that these semiperfect-information turn-based games are equivalent to perfect-information concurrent games, where the two players choose their moves simultaneously and independently. Since the perfect-information concurrent games are well-understood, we obtain several results of how semiperfect-information turn-based games differ from perfect-information turn-based games on one hand, and from partial-information turn-based games on the other hand. In particular, semiperfect-information turn-based games can benefit from randomized strategies while the perfect-information variety cannot, and semiperfect-information turn-based games are in NP ∩ coNP for all parity objectives.

text: 'The theory of graph games with ω-regular winning conditions is the foundation
for modeling and synthesizing reactive processes. In the case of stochastic reactive
processes, the corresponding stochastic graph games have three players, two of
them (System and Environment) behaving adversarially, and the third (Uncertainty)
behaving probabilistically. We consider two problems for stochastic graph games:
the qualitative problem asks for the set of states from which a player can win
with probability 1 (almost-sure winning); the quantitative problem asks for the
maximal probability of winning (optimal winning) from each state. We show that
for Rabin winning conditions, both problems are in NP. As these problems were
known to be NP-hard, it follows that they are NP-complete for Rabin conditions,
and dually, coNP-complete for Streett conditions. The proof proceeds by showing
that pure memoryless strategies suffice for qualitatively and quantitatively winning
stochastic graph games with Rabin conditions. This insight is of interest in its
own right, as it implies that controllers for Rabin objectives have simple implementations.
We also prove that for every ω-regular condition, optimal winning strategies are
no more complex than almost-sure winning strategies.'

text: Games played on graphs may have qualitative objectives, such as the satisfaction
of an ω-regular property, or quantitative objectives, such as the optimization
of a real-valued reward. When games are used to model reactive systems with both
fairness assumptions and quantitative (e.g., resource) constraints, then the corresponding
objective combines both a qualitative and a quantitative component. In a general
case of interest, the qualitative component is a parity condition and the quantitative
component is a mean-payoff reward. We study and solve such mean-payoff parity
games. We also prove some interesting facts about mean-payoff parity games which
distinguish them both from mean-payoff and from parity games. In particular, we
show that optimal strategies exist in mean-payoff parity games, but they may require
infinite memory.

text: 'Planning in adversarial and uncertain environments can be modeled as the
problem of devising strategies in stochastic perfect information games. These
games are generalizations of Markov decision processes (MDPs): there are two (adversarial)
players, and a source of randomness. The main practical obstacle to computing
winning strategies in such games is the size of the state space. In practice therefore,
one typically works with abstractions of the model. The diffculty is to come up
with an abstraction that is neither too coarse to remove all winning strategies
(plans), nor too fine to be intractable. In verification, the paradigm of counterexample-guided
abstraction refinement has been successful to construct useful but parsimonious
abstractions automatically. We extend this paradigm to probabilistic models (namely,
perfect information games and, as a special case, MDPs). This allows us to apply
the counterexample-guided abstraction paradigm to the AI planning problem. As
special cases, we get planning algorithms for MDPs and deterministic systems that
automatically construct system abstractions.'

text: Among various types of low- and high-threshold calcium channels, the high
voltage-activated P/Q-type channel is the most abundant in the cerebellum. These
P/Q-type channels are involved in the regulation of neurotransmitter release and
in the integration of dendritic inputs. We used an antibody specific for the α1A
subunit of the P/Q-type channel in quantitative pre-embedding immunogold labelling
combined with three-dimensional reconstruction to reveal the subcellular distribution
of pre- and postsynaptic P/Q-type channels in the rat cerebellum. At the light
microscopic level, immunoreactivity for the α1A protein was prevalent in the molecular
layer, whereas immunostaining was moderate in the somata of Purkinje cells and
weak in the granule cell layer. At the electron microscopic level, the most intense
Immunoreactivity for the α1A subunit was found in the presynaptic active zone
of parallel fibre varicosities. The dendritic spines of Purkinje cells were also
strongly labelled with the highest density of immunoparticles detected within
180 nm from the edge of the asymmetrical parallel fibre-Purkinje cell synapses.
By contrast, the immunolabelling was sparse in climbing fibre varicosities and
axon terminals of GABAergic cells, and weak and diffuse in dendritic shafts of
Purkinje cells. The association of the α1A subunit with the glutamatergic parallel
fibre-Purkinje cell synapses suggests that presynaptic channels have a major role
in the mediation of excitatory neurotransmission, whereas postsynaptic channels
are likely to be involved in depolarization-induced generation of local calcium
transients in Purkinje cells.

text: Vesicular glutamate transporter type 3 (VGLUT3) containing neuronal elements
were characterized using antibodies to VGLUT3 and molecular cell markers. All
VGLUT3-positive somata were immunoreactive for CCK, and very rarely, also for
calbindin; none was positive for parvalbumin, calretinin, VIP or somatostatin.
In the CA1 area, 26.8 ± 0.7% of CCK-positive interneuron somata were VGLUT3-positive,
a nonoverlapping 22.8 ± 1.9% were calbindin-positive, 10.7 ± 2.5% VIP-positive
and the rest were only CCK-positive. The patterns of coexpression were similar
in the CA3 area, the dentate gyrus and the isocortex. Immunoreactivity for VGLUT3
was undetectable in pyramidal and dentate granule cells. Boutons colabelled for
VGLUT3, CCK and GAD were most abundant in the cellular layers of the hippocampus
and in layers II-III of the isocortex. Large VGLUT3-labelled boutons at the border
of strata radiatum and lacunosum-moleculare in the CA1 area were negative for
GAD, but were labelled for vesicular monoamine transporter type 2, plasmalemmal
serotonin transporter or serotonin. No colocalization was found in terminals between
VGLUT3 and parvalbumin, vesicular acetylcholine transporter and group III (mGluR7a,b;
mGluR8a,b) metabotropic glutamate receptors. In stratum radiatum and the isocortex,
VGLUT3-positive but GAD-negative boutons heavily innervated the soma and proximal
dendrites of some VGLUT3- or calbindin-positive interneurons. The results suggest
that boutons coexpressing VGLUT3, CCK and GAD originate from CCK-positive basket
cells, which are VIP-immunonegative. Other VGLUT3-positive boutons immunopositive
for serotonergic markers but negative for GAD probably originate from the median
raphe nucleus and innervate select interneurons. The presumed amino acid substrate
of VGLUT3 may act on presynaptic kainate or group II metabotropic glutamate receptors.

text: Hyperpolarization-activated cation currents (Ih) contribute to various physiological
properties and functions in the brain, including neuronal pacemaker activity,
setting of resting membrane potential, and dendritic integration of synaptic input.
Four subunits of the Hyperpolarization-activated and Cyclic-Nucleotide-gated nonselective
cation channels (HCN1-4), which generate Ih, have been cloned recently. To better
understand the functional diversity of Ih in the brain, we examined precise immunohistochemical
localization of four HCNs in the rat brain. Immunoreactivity for HCN1 showed predominantly
cortical distribution, being intense in the neocortex, hippocampus, superior colliculus,
and cerebellum, whereas those for HCN3 and HCN4 exhibited subcortical distribution
mainly concentrated in the hypothalamus and thalamus, respectively. Immunoreactivity
for HCN2 had a widespread distribution throughout the brain. Double immunofluorescence
revealed colocalization of immunoreactivity for HCN1 and HCN2 in distal dendrites
of pyramidal cells in the hippocampus and neocortex. At the electron microscopic
level, immunogold particles for HCN1 and HCN2 had similar distribution patterns
along plasma membrane of dendritic shafts in layer I of the neocortex and stratum
lacunosum moleculare of the hippocampal CA1 area, suggesting that these subunits
could form heteromeric channels. Our results further indicate that HCNs are localized
not only in somato-dendritic compartments but also in axonal compartments of neurons.
Immunoreactivity for HCNs often occurred in preterminal rather than terminal portions
of axons and in specific populations of myelinated axons. We also found HCN2-immunopositive
oligodendrocytes including perineuronal oligodendrocytes throughout the brain.
These results support previous electrophysiological findings and further suggest
unexpected roles of Ih channels in the brain.

text: The Na+-K+ pump current (Ip) and the h-current (Ih) flowing through hyperpolarization-activated
channels (h-channels) participate in generating the resting potential. These two
currents are thought to be produced independently. We show here bidirectional
interactions between Na+-K+ pumps and h-channels in mesencephalic trigeminal neurons.
Activation of Ih leads to the generation of two types of ouabain-sensitive Ip
with temporal profiles similar to those of instantaneous and slow components of
I h, presumably reflecting Na+ transients in a restricted cellular space. Moreover,
the Ip activated by instantaneous I h can facilitate the subsequent activation
of slow Ih. Such counteractive and cooperative interactions were also disclosed
by replacing extracellular Na+ with Li+, which is permeant through h-channels
but does not stimulate the Na+-K+ pump as strongly as Na+ ions. These observations
indicate that the interactions are bidirectional and mediated by Na+ ions. Also
after substitution of extracellular Na+ with Li+, the tail Ih was reduced markedly
despite an enhancement of Ih itself, attributable to a negative shift of the reversal
potential for I h presumably caused by intracellular accumulation of Li+ ions.
This suggests the presence of a microdomain where the interactions can take place.
Thus, the bidirectional interactions between Na+-K + pumps and h-channels are
likely to be mediated by Na+ microdomain. Consistent with these findings, hyperpolarization-activated
and cyclic nucleotide-modulated subunits (HCN1/2) and the Na+-K + pump α3 isoform
were colocalized in plasma membrane of mesencephalic trigeminal neurons having
numerous spines.

text: In the hippocampal CA1 region, metabotropic glutamate subtype 1 (mGluR1) receptors
have been implicated in a variety of physiological responses to glutamate, which
include modulation of synaptic transmission and plasticity, as well as neuronal
excitability and synchronization. The mGluR1α isoform is characteristically expressed
only by nonprincipal cells, and it is particularly enriched in somatostatin (SS
-containing interneurons in stratum oriens-alveus. Anatomical and physiological
data have indicated the presence of mGluR1α in several distinct classes of interneurons
with their somata located also in strata pyramidale, radiatum, and lacunosum moleculare.
Each different interneuron subtype, as defined by functionally relevant criteria,
including input/output characteristics and expression of selective molecular markers,
subserves distinct functions in local hippocampal circuits. We have investigated
which of the different CA1 interneuron classes express mGluR1α by immunofluorescent
labeling, combining antibodies to mGluR1α, calcium-binding proteins, and neuropeptides,
and by intracellular labeling in vitro. Several types of interneuron that are
immunopositive for mGluR1α each targeted different domains of pyramidal cells
and included (1) O-LM interneurons, found to coexpress both SS and parvalbumin
(PV); (2) interneurons with target selectivity for other interneurons, expressing
vasoactive intestinal polypeptide (VIP) and/or the calcium-binding protein calretinin;
(3) procholecystokinin-immunopositive interneurons probably non-basket and dendrite-targeting;
and (4) an as-yet unidentified SS-immunoreactive but PV-immunonegative interneuron
class, possibly corresponding to oriensbistratified cells. Estimation of the relative
proportion of mGluR1α-positive interneurons showed 43%, 46%, and 30% co-labeling
with SS, VIP, or PV, respectively. The identification of the specific subclasses
of CA1 interneurons expressing mGluR1α provides the network basis for assessing
the contribution of this receptor to the excitability of the hippocampus.

text: Metabotropic γ-aminobutyric acid receptors (GABAB) are involved in pre- and
postsynaptic inhibitory effects upon auditory neurons and have been implicated
in different aspects of acoustic information processing. To understand better
the mechanisms by which GABAB receptors mediate their inhibitory effects, we used
pre-embedding immunocytochemical techniques combined with quantification of immunogold
particles to reveal the precise subcellular distribution of the GABAB1 subunit
in the rat dorsal cochlear nucleus. At the light microscopic level, GABAB1 was
detected in all divisions of the cochlear complex. The most intense immunoreactivity
for GABAB1 was found in the dorsal cochlear nucleus, whereas immunoreactivity
in the anteroventral and posteroventral cochlear nuclei was very low. In the dorsal
cochlear nucleus, a punctate labeling was observed in the superficial (molecular
and fusiform cell) layers. At the electron microscopic level, GABAB1 was found
at both post- and presynaptic locations. Postsynaptically, GABAB1 was localized
mainly in the dendritic spines of presumed fusiform cells. Quantitative immunogold
immunocytochemistry revealed that the highest concentration of GABA B1 in the
plasma membrane was in dendritic spines, followed by dendritic shafts and somata.
Thus, the most intense immunoreactivity for GABAB1 was observed in dendritic spines
with a high density of immunogold particles at extrasynaptic sites, peaking around
300 nm from glutamatergic synapses. This is in contrast to GABAergic synapses,
in which GABAB1 was only occasionally found. Presynaptically, receptor immunoreactivity
was detected primarily in axospinous endings, probably from granule cells, in
both the active zone and extrasynaptic sites. The localization of GABAB1 relative
to synaptic sites in the DCN suggests a role for the receptor in the regulation
of dendritic excitability and excitatory inputs.

text: The release of GABA in synapses is modulated by presynaptic metabotropic glutamate
receptors (mGluRs). We tested whether GABA release to identified hippocampal neurons
is influenced by group III mGluR activation using the agonist L-(+)-2-amino-4-phosphonobutyric
acid (L-AP4) on inhibitory postsynaptic currents (IPSCs) evoked in CA1 interneurons
and pyramidal cells. In interneurons, characterized with biocytin and immunolabelling
for somatostatin, evoked IPSCs were depressed by 50 μM L-AP4 (activating mGluR4
and 8) to 68±6% of control, but they were rarely depressed in pyramidal cells
(96±4% of control). At 300-500 μM concentration (activating mGluR4, 7 and 8),
L-AP4 depressed IPSCs in both interneurons (to 70±6%) and pyramidal cells (to
67±4%). The change in trial-to-trial variability and in paired-pulse depression
indicated a presynaptic action. In interneurons, the degree of IPSC depression
was variable (to 9-87%), and a third of IPSCs were not affected by L-AP4. The
L-AP4-evoked IPSC depression was blocked by LY341495. The depression of IPSCs
was similar in O-LM cells and other interneurons. The lack of cell-type selectivity
and the similar efficacy of different concentrations of L-AP4 suggest that several
group III mGluRs are involved in the depression of IPSCs. Electron microscopic
immunocytochemistry confirmed that mGluR4, mGluR7a and mGluR8a occur in the presynaptic
active zone of GABAergic terminals on interneurons, but not on those innervating
pyramidal cells. The high variability of L-AP4-evoked IPSC suppression is in line
with the selective expression of presynaptic mGluRs by several distinct types
of GABAergic neuron innervating each interneuron type.

text: 'The globus pallidus (GP) is a critical component of the basal ganglia circuitry
controlling motor behavior. Dysregulation of GP activity has been implicated in
a number of psychomotor disorders, including Parkinson''s disease (PD), in which
a cardinal feature of the pathophysiology is an alteration in the pattern and
synchrony of discharge in GP neurons. Yet the determinants of this activity in
GP neurons are poorly understood. To help fill this gap, electrophysiological,
molecular, and computational approaches were used to identify and characterize
GABAergic GP neurons in tissue slices from rodents. In vitro, GABAergic GP neurons
generate a regular, autonomous, single-spike pacemaker activity. Hyperpolarization-activated,
cyclic nucleotide-gated cation (HCN) channels make an important contribution to
this process: their blockade with ZD7288 significantly slowed discharge rate and
decreased its regularity. HCN currents evoked by somatic voltage clamp had fast
and slow components. Single-cell RT-PCR and immunohistochemical approaches revealed
robust expression of HCN2 subunits as well as significant levels of HCN1 subunits
in GABAergic GP neurons. Transient activation of striatal GABAergic input to GP
neurons led to a resetting of rhythmic discharge that was dependent on HCN currents.
Simulations suggested that the ability of transient striatal GABAergic input to
reset pacemaking was dependent on dendritic HCN2/HCN1 channels. Together, these
studies show that HCN channels in GABAergic GP neurons are key determinants of
the regularity and rate of pacemaking as well as striatal resetting of this activity,
implicating HCN channels in the emergence of synchrony in PD.'

text: Metabotropic γ-aminobutyric acid receptors (GABAB) play modulatory roles in
central synaptic transmission and are involved in controlling neuronal migration
during development. We used immunohistochemical methods to elucidate the expression
pattern as well as the cellular and the precise subcellular localization of the
GABAB1a/b and GABAB2 subunits in the rat hippocampus during prenatal and postnatal
development. At the light microscopic level, both GABABB1a/b and GABAB2 were expressed
in the hippocampal primordium from embryonic day E14. During postnatal development,
immunoreactivity for GABAB1a/b and GABAB2 was distributed mainly in pyramidal
cells, with discrete GABABB1a/b-immunopositive cell bodies of interneurons present
throughout the hippocampus. Using double immunofluorescence, we demonstrated that
during the second week of postnatal development, GABAB1a/b but not GABAB2 was
expressed in glial cells throughout the hippocampal formation. At the electron
microscopic level, GABAB1a/b and GABAB2 showed a similar distribution pattern
during postnatal development. Thus, at all ages the two receptor subunits were
located postsynaptically in dendritic spines and shafts at extrasynaptic and perisynaptic
sites in both pyramidal and nonpyramidal cells. We further demonstrated that the
two subunits were localized presynaptically along the extrasynaptic plasma membrane
of axon terminals and along the presynaptic active zone in both asymmetrical and,
to a lesser extent, symmetrical synapses. These results suggest that GABAB receptors
are widely expressed in the hippocampus throughout development and that GABABB1a/b
and GABAB2 form both pre- and postsynaptic receptors.

text: The Pauli operator describes the energy of a nonrelativistic quantum particle
with spin in a magnetic field and an external potential. Bounds on the sum of
the negative eigenvalues are called magnetic Lieb-Thirring (MLT) inequalities.
The purpose of this paper is twofold. First, we prove a new MLT inequality in
a simple way. Second, we give a short summary of our recent proof of a more refined
MLT inequality(8) and we explain the differences between the two results and methods.
The main feature of both estimates, compared to earlier results, is that in the
large field regime they grow with the optimal (first) power of the strength of
the magnetic field. As a byproduct of the method, we also obtain optimal upper
bounds on the pointwise density of zero energy eigenfunctions of the Dirac operator.

text: We give a nonrigorous derivation of the nonlinear Boltzmann equation from
the Schrödinger evolution of interacting fermions. The argument is based mainly
on the assumption that a quasifree initial state satisfies a property called restricted
quasifreeness in the weak coupling limit at any later time. By definition, a state
is called restricted quasifree if the four-point and the eight-point functions
of the state factorize in the same manner as in a quasifree state.
