text: "Giotto provides a time-triggered programmer’s model for the implementation
of embedded control systems with hard real-time constraints. Giotto’s precise
semantics and predictabil- ity make it suitable for safety-critical applications.\r\nGiotto
is based around the idea that time-triggered task invocation together with time-triggered
mode switching can form a useful programming model for real-time systems. To substantiate
this claim, we describe the use of Giotto to refactor the software of a small,
autonomous helicopter. The ease with which Giotto expresses the existing software
provides evidence that Giotto is an appropriate programming language for control
systems.\r\nSince Giotto is a real-time programming language, ensuring that Giotto
programs meet their deadlines is crucial. To study precedence-constrained Giotto
scheduling, we first examine single-mode, single-processor scheduling. We extend
to an infinite, periodic setting the classical problem of meeting deadlines for
a set of tasks with release times, deadlines, precedence constraints, and preemption.
We then develop an algorithm for scheduling Giotto programs on a single processor
by representing Giotto programs as instances of the extended scheduling problem.\r\nNext,
we study multi-mode, single-processor Giotto scheduling. This problem is different
from classical scheduling problems, since in our precedence-constrained approach,
the deadlines of tasks may vary depending on the mode switching behavior of the
program. We present conditional scheduling models which capture this varying-deadline
behavior. We develop polynomial-time algorithms for some conditional scheduling
models, and prove oth- ers to be computationally hard. We show how to represent
multi-mode Giotto programs as instances of the model, resulting in an algorithm
for scheduling multi-mode Giotto programs on a single processor.\r\nFinally, we
show that the problem of scheduling Giotto programs for multiple net- worked processors
is strongly NP-hard."

text: "Symbolic model checking, which enables the automatic verification of large
systems, proceeds by calculating expressions that represent state sets. Traditionally,
symbolic model-checking tools are based on back- ward state traversal; their basic
operation is the function pre, which, given a set of states, returns the set of
all predecessor states. This is because specifiers usually employ formalisms with
future-time modalities, which are naturally evaluated by iterating applications
of pre. It has been shown experimentally that symbolic model checking can perform
significantly better if it is based, instead, on forward state traversal; in this
case, the basic operation is the function post, which, given a set of states,
returns the set of all successor states. This is because forward state traversal
can ensure that only parts of the state space that are reachable from an initial
state and relevant for the satisfaction or violation of the specification are
explored; that is, errors can be detected as soon as possible.\r\nIn this paper,
we investigate which specifications can be checked by symbolic forward state traversal.
We formulate the problems of symbolic backward and forward model checking by means
of two μ-calculi. The pre-μ calculus is based on the pre operation, and the post-μ
calculus is based on the post operation. These two μ-calculi induce query logics,
which augment fixpoint expressions with a boolean emptiness query. Using query
logics, we are able to relate and compare the symbolic backward and forward approaches.
In particular, we prove that all ω-regular (linear-time) specifications can be
expressed as post-μ queries, and therefore checked using symbolic forward state
traversal. On the other hand, we show that there are simple branching-time specifications
that cannot be checked in this way."

text: 'A major hurdle in the algorithmic verification and control of systems is
the need to find suitable abstract models, which omit enough details to overcome
the state-explosion problem, but retain enough details to exhibit satisfaction
or controllability with respect to the specification. The paradigm of counterexample-guided
abstraction refinement suggests a fully automatic way of finding suitable abstract
models: one starts with a coarse abstraction, attempts to verify or control the
abstract model, and if this attempt fails and the abstract counterexample does
not correspond to a concrete counterexample, then one uses the spurious counterexample
to guide the refinement of the abstract model. We present a counterexample-guided
refinement algorithm for solving ω-regular control objectives. The main difficulty
is that in control, unlike in verification, counterexamples are strategies in
a game between system and controller. In the case that the controller has no choices,
our scheme subsumes known counterexample-guided refinement algorithms for the
verification of ω-regular specifications. Our algorithm is useful in all situations
where ω-regular games need to be solved, such as supervisory control, sequential
and program synthesis, and modular verification. The algorithm is fully symbolic,
and therefore applicable also to infinite-state systems.'

text: We present an algorithm called TAR (“Thread-modular Abstraction Refinement”)
for model checking safety properties of concurrent software. The TAR algorithm
uses thread-modular assume-guarantee reasoning to overcome the exponential complexity
in the control state of multithreaded programs. Thread modularity means that TAR
explores the state space of one thread at a time, making assumptions about how
the environment can interfere. The TAR algorithm uses counterexample-guided predicate-abstraction
refinement to overcome the usually infinite complexity in the data state of C
programs. A successive approximation scheme automatically infers the necessary
precision on data variables as well as suitable environment assumptions. The scheme
is novel in that transition relations are approximated from above, while at the
same time environment assumptions are approximated from below. In our software
verification tool BLAST we have implemented a fully automatic race checker for
multithreaded C programs which is based on the TAR algorithm. This tool has verified
a wide variety of commonly used locking idioms, including locking schemes that
are not amenable to existing dynamic and static race checkers such as ERASER or
WARLOCK.

text: We introduce the paradigm of schedule-carrying code (SCC). A hard real-time
program can be executed on a given platform only if there exists a feasible schedule
for the real-time tasks of the program. Traditionally, a scheduler determines
the existence of a feasible schedule according to some scheduling strategy. With
SCC, a compiler proves the existence of a feasible schedule by generating executable
code that is attached to the program and represents its schedule. An SCC executable
is a real-time program that carries its schedule as code, which is produced once
and can be revalidated and executed with each use. We evaluate SCC both in theory
and practice. In theory, we give two scenarios, of nonpreemptive and distributed
scheduling for Giotto programs, where the generation of a feasible schedule is
hard, while the validation of scheduling instructions that are attached to the
programs is easy. In practice, we implement SCC and show that explicit scheduling
instructions can reduce the scheduling overhead up to 35% and can provide an efficient,
flexible, and verifiable means for compiling Giotto programs on complex architectures,
such as the TTA.

text: Giotto is a principled, tool-supported design methodology for implementing
embedded control systems on platforms of possibly distributed sensors, actuators,
CPUs, and networks. Giotto is based on the principle that time-triggered task
invocations plus time-triggered mode switches can form the abstract essence of
programming real-time control systems. Giotto consists of a programming language
with a formal semantics, and a retargetable compiler and runtime library. Giotto
supports the automation of control system design by strictly separating platform-independent
functionality and timing concerns from platform-dependent scheduling and communication
issues. The time-triggered predictability of Giotto makes it particularly suitable
for safety-critical applications with hard real-time constraints. We illustrate
the platform independence and time-triggered execution of Giotto by coordinating
a heterogeneous flock of Intel x86 robots and Lego Mindstorms robots.

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 alternationfree 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: 'BLAST (the Berkeley Lazy Abstraction Software verification Tool) is a verification
system for checking safety properties of C programs using automatic property-driven
construction and model checking of software abstractions. Blast implements an
abstract-model check-refine loop to check for reachability of a specified label
in the program. The abstract model is built on the fly using predicate abstraction.
This model is then checked for reachability. If there is no (abstract) path to
the specified error label, Blast reports that the system is safe and produces
a succinct proof. Otherwise, it checks if the path is feasible using symbolic
execution of the program. If the path is feasible, Blast outputs the path as an
error trace, otherwise, it uses the infeasibility of the path to refine the abstract
model. Blast short-circuits the loop from abstraction to verification to refinement,
integrating the three steps tightly through “lazy abstraction” [5]. This integration
can offer significant advantages in performance by avoiding the repetition of
work from one iteration of the loop to the next. '

text: Giotto provides an abstract programmer's model for the implementation of embedded
control systems with hard real-time constraints. A typical control application
consists of periodic software tasks together with a mode-switching logic for enabling
and disabling tasks. Giotto specifies time-triggered sensor readings, task invocations,
actuator updates, and mode switches independent of any implementation platform.
Giotto can be annotated with platform constraints such as task-to-host mappings,
and task and communication schedules. The annotations are directives for the Giotto
compiler, but they do not alter the functionality and timing of a Giotto program.
By separating the platform-independent from the platform-dependent concerns, Giotto
enables a great deal of flexibility in choosing control platforms as well as a
great deal of automation in the validation and synthesis of control software.
The time-triggered nature of Giotto achieves timing predictability, which makes
Giotto particularly suitable for safety-critical applications.
acknowledgement: The authors would like to thank R. Majumdar for implementing a prototype
Giotto compiler for Lego Mindstorms robots. They would like to thank D. Derevyanko
and W. Williams for building the Intel x86 robots; and E. Lee and X. Liu for help
with implementing Giotto as a “model of computation” in Ptolemy II [26]. Finally,
they would also like to thank M. Sanvido for his suggestions on the design of the
Giotto drivers; and P. Griffiths for implementing the functionality code of the
electronic throttle controller.

text: In this investigation, we report identification and characterization of a
95 kDa postsynaptic density protein (PSD-95)/discs-large/ ZO-1 (PDZ) domain-containing
protein termed tamalin, also recently named GRP1-associated scaffold protein (GRASP),
that interacts with group 1 metabotropic glutamate receptors (mGluRs). The yeast
two-hybrid system and in vitro pull-down assays indicated that the PDZ domain-containing,
amino-terminal half of tamalin directly binds to the class I PDZ-binding motif
of group 1 mGluRs. The C-terminal half of tamalin also bound to cytohesins, the
members of guanine nucleotide exchange factors (GEFs) specific for the ADP-ribosylation
factor (ARF) family of small GTP-binding proteins. Tamalin mRNA is expressed predominantly
in the telencephalic region and highly overlaps with the expression of group 1
mGluR mRNAs. Both tamalin and cytohesin-2 were enriched and codistributed with
mGluR1a in postsynaptic membrane fractions. Importantly, recombinant and native
mGluR1a/tamalin/cytohesin-2 complexes were coimmunoprecipitated from transfected
COS-7 cells and rat brain tissue, respectively. Transfection of tamalin and mutant
tamalin lacking a cytohesin-binding domain caused an increase and decrease in
cell-surface expression of mGluR1a in COS-7 cells, respectively. Furthermore,
adenovirus-mediated expression of tamalin and dominant-negative tamalin facilitated
and reduced the neuritic distribution of endogenous mGluR5 in cultured hippocampal
neurons, respectively. The results indicate that tamalin plays a key role in the
association of group 1 mGluRs with the ARF-specific GEF proteins and contributes
to intracellular trafficking and the macromolecular organization of group 1 mGluRs
at synapses.

text: Metabotropic glutamate receptors (mGluRs) from group III reduce glutamate
release. Because these receptors reduce cAMP levels, we explored whether this
signaling pathway contributes to release inhibition caused by mGluRs with low
affinity for L-2-amino-4-phosphonobutyrate (L-AP4). In biochemical experiments
with the population of cerebrocortical nerve terminals we find that L-AP4 (1 mM)
inhibited the Ca2+dependent-evoked release of glutamate by 25%. This inhibitory
effect was largely prevented by the pertussis toxin but was insensitive to inhibitors
of protein kinase C bisindolylmaleimide and protein kinase A H-89. Furthermore,
this inhibition was associated with reduction in N-type Ca2+ channel activity
in the absence of any detectable change in cAMP levels. In the presence of forskolin,
however, L-AP4 decreased the levels of cAMP. The activation of this additional
signaling pathway was very efficient in counteracting the facilitation of glutamate
release induced either by forskolin or the β-adrenergic receptor agonist isoproterenol.
Imaging experiments to measure Ca2+ dynamics in single nerve terminals showed
that L-AP4 strongly reduced the Ca2+ response in 28% of the nerve terminals. Moreover,
immunochemical experiments showed that 25-35% of the nerve terminals that were
immunopositive to synaptophysin were also immunoreactive to the low affinity L-AP4-sensitive
mGluR7. Then, mGluR7 mediates the inhibition of glutamate release caused by 1
mM L-AP4, primarily by a strong inhibition of Ca2+ channels, although high cAMP
uncovers the receptor ability to decrease cAMP.

text: Taste-mGluR4, cloned from taste tissues, is a truncated variant of brain-expressed
mGluR4a (brain-mGluR4), and is known to be a candidate for the receptor involved
in the umami taste sense. Although the expression patterns of taste- and brain-mGluR4
mRNAs have been demonstrated, no mention has so far been made of the expression
of these two mGluR4 proteins in taste tissues. The present study examined the
expression of taste-mGluR4 and brain-mGluR4 proteins in rat taste tissues by using
a specific antibody for mGluR4a which shared a C-terminus of both taste- and brain-mGluR4,
for immunoblot analysis and immunohistochemistry. Immunoblot analysis showed that
both brain-mGluR4 and taste-mGluR4 were expressed in the taste tissues. Taste-mGluR4
was not detected in the cerebellum. The immunoreactive band for brain-mGluR4 protein
was much stronger than that for taste-mGluR4 protein. In the cryosections of fungiform,
foliate and circumvallate papillae, the antibody against taste-mGluR4 exhibited
intense labeling of the taste pores and taste hairs in all the taste buds of gustatory
papillae examined; the immunoreaction to the antibody against brain-mGluR4 was
more intense at the same sites of the taste buds. The portions of the taste bud
cells below the taste pore and surrounding keratinocytes did not show any immunoreactivities.
The results of the present study strongly suggest that, in addition to taste-mGluR4,
brain-mGluR4 may function even more importantly than the former as a receptor
for glutamate, i.e. the umami taste sensation.

text: Neurons in the rat cerebral cortex are enriched in group I metabotropic glutamate
receptor (mGluR) subtypes and respond to their activation during development.
To understand better the mechanisms by which mGluR1 and mGluR5 mediate these effects,
the goal of this study was to elucidate the expression pattern and to determine
the cellular and the precise subcellular localization of these two receptor subtypes
in the rat neocortex and hippocampus during late prenatal and postnatal development.
At the light microscopic level, mGluR1 α and mGluR5 were first detected in the
cerebral cortex with different expression levels at embryonic day E18. Thus, mGluR5
had a moderate expression, whereas mGluR1 α was detected as a diffuse and weak
labeling. mGluR5 was localized in some Cajal-Retzius cells as well as in other
cell types, such as pioneer neurons of the marginal zone. During postnatal development,
the distribution of the receptors dramatically changed. From P0 to around P10,
mGluR1α was localized in identified, transient Cajal-Retzius cells of neocortex
and hippocampus, until these cells disappear. In addition, a population of interneurons
localized the receptor from the second/third postnatal week. In contrast, mGluR5
was localized mainly in pyramidal cells and in some interneurons, with a neuropilar
staining throughout the cerebral cortex. At the electron microscopic level, the
immunoreactivity for both group I mGluR subtypes was expressed postsynaptically.
Using immunogold methods, mGluR1α and mGluR5 immunoreactivities were found throughout
postnatal development at the edge of postsynaptic specialization of asymmetrical
synapses. These results show that the two group I mGluRs have a differential expression
pattern in neocortex and hippocampus that may suggest roles for the receptors
in the early processing of cortical information and in the control of cortical
developmental events.

text: Synapses exhibit different short-term plasticity patterns and this behaviour
influences information processing in neuronal networks. We tested how the short-term
plasticity of excitatory postsynaptic currents (EPSCs) depends on the postsynaptic
cell type, identified by axonal arborizations and molecular markers in the hippocampal
CA1 area. Three distinct types of short-term synaptic behaviour (facilitating,
depressing and combined facilitating-depressing) were defined by fitting a dynamic
neurotransmission model to the data. Approximately 75 % of the oriens-lacunosum-moleculare
(O-LM) interneurones received facilitating EPSCs, but in three of 12 O-LM cells
EPSCs also showed significant depression. Over 90 % of the O-LM cells were immunopositive
for somatostatin and mGluR1α and all tested cells were decorated by strongly mGluR7a
positive axon terminals. Responses in eight of 12 basket cells were described
well with a model involving only depression, but the other cells displayed combined
facilitating-depressing EPSCs. No apparent difference was found between the plasticity
of EPSCs in cholecystokinin- or parvalbumin-containing basket cells. In oriens-bistratified
cells (O-Bi), two of nine cells showed facilitating EPSCs, another two depressing,
and the remaining five cells combined facilitating-depressing EPSCs. Seven of
10 cells tested for somatostatin were immunopositive, but mGluR1α was detectable
only in two of 11 tested cells. Furthermore, most O-Bi cells projected to the
CA3 area and the subiculum, as well as outside the hippocampal formation. Postsynaptic
responses to action potentials recorded in vivo from a CA1 place cell were modelled,
and revealed great differences between and within cell types. Our results demonstrate
that the short-term plasticity of EPSCs is cell type dependent, but with significant
heterogeneity within all three interneurone populations.

text: The unipolar brush cell (UBC) is a type of glutamatergic interneuron in the
granular layer of the cerebellum. The UBC brush and a single mossy fiber (MF)
terminal contact each other within a cerebellar glomerulus, forming a giant synapse.
Many UBCs receive input from extrinsic MFs, whereas others are innervated by intrinsic
mossy terminals formed by the axons of other UBCs. In all mammalian species so
far examined, the vestibulocerebellum is enriched of UBCs that are strongly immunoreactive
for the calcium binding protein calretinin (CR) in both the somatodendritic and
axonal compartment. UBCs have postsynaptic ionotropic glutamate receptors and
extrasynaptic metabotropic glutamate receptors that immunocytochemically highlight
their somatodendritic compartment and brush, respectively. In this study on the
mouse cerebellum, we present evidence that immunoreactivities to CR and mGluR1α
define two distinct UBC subsets with partly overlapping distributions in lobule
X (the nodulus). In sections double-labeled for CR and mGluR1α, the patterns of
distributions of CR+/mGluR1α- UBCs and CR-/mGluR1α+ UBCs differed along the mediolateral
and dorsoventral axes of the folium. Moreover, mGluR1α+ UBCs outnumbered CR+ UBCs.
Both UBC subsets were mGluR2/3, GluR2/3, and NMDAR1 immunoreactive. The different
distribution patterns of the two UBC subsets within lobule X suggest that expression
of CR or mGluR1α by UBCs may be afferent-specific and related to the terminal
fields of different vestibular MF afferents.

text: The release of glutamate and GABA is modulated by presynaptic metabotropic
glutamate receptors (mGluRs). We used immunocytochemical methods to define the
location of the group III receptor mGluR7a in glutamatergic and GABAergic terminals
innervating GABAergic interneurons and pyramidal cells. Immunoreactivity for mGluR7a
was localized in the presynaptic active zone of both identified GABAergic and
presumed glutamatergic terminals. Terminals innervating dendritic spines showed
a variable level of receptor immunoreactivity, ranging from immunonegative to
strongly immunopositive. The frequency of strongly mGluR7a positive terminals
innervating the soma and dendrites of mGluR1α/somatostatin-expressing interneurons
was very high relative to other neurons. On dendrites that received mGluR7a-enriched
glutamatergic innervation, at least 80% of GABAergic terminals were immunopositive
for mGluR7a. On such dendrites virtually all (95%) vasoactive intestinal polypeptide
(VIP) positive (GABAergic) terminals were enriched in mGluR7a. The targets of
VIP/mGluR7a-expressing terminals were mainly (88%) mGluR1α-expressing interneurons,
which were mostly somatostatin immunopositive. Parvalbumin positive terminals
were immunonegative for mGluR7a. Some parvalbumin immunoreactive dendrites received
strongly mGluR7a positive terminals. The subcellular location, as well as the
cell type and synapse-specific distribution of mGluR7a in isocortical neuronal
circuits, is homologous to its distribution in the hippocampus. The specific location
of mGluR7a in the presynaptic active zone of both glutamatergic and GABAergic
synapses may be related to the proximity of calcium channels and the vesicle fusion
machinery. The enrichment of mGluR7a in the main GABAergic, as well as in the
glutamatergic, innervation of mGluR1α/somatostatin-expressing interneurons suggests
that their activation is under unique regulation by extracellular glutamate.

text: An ion channel's function depends largely on its location and density on neurons.
Here we used high-resolution immunolocalization to determine the subcellular distribution
of the hyperpolarization-activated and cyclic-nucleotide-gated channel subunit
1 (HCN1) in rat brain. Light microscopy revealed graded HCN1 immunoreactivity
in apical dendrites of hippocampal, subicular and neocortical layer-5 pyramidal
cells. Quantitative comparison of immunogold densities showed a 60-fold increase
from somatic to distal apical dendritic membranes. Distal dendritic shafts had
16 times more HCN1 labeling than proximal dendrites of similar diameters. At the
same distance from the soma, the density of HCN1 was significantly higher in dendritic
shafts than in spines. Our results reveal the complex cell surface distribution
of voltage-gated ion-channels, and predict its role in increasing the computational
power of single neurons via subcellular domain and input-specific mechanisms.

text: The release properties of glutamatergic nerve terminals are influenced by
a number of factors, including the subtype of voltage-dependent calcium channel
and the presence of presynaptic autoreceptors. Group III metabotropic glutamate
receptors (mGluRs) mediate feedback inhibition of glutamate release by inhibiting
Ca2+ channel activity. By imaging Ca2+ in preparations of cerebrocortical nerve
terminals, we show that voltage-dependent Ca2+ channels are distributed in a heterogeneous
manner in individual nerve terminals. Presynaptic terminals contained only N-type
(47.5%; conotoxin GVIA-sensitive), P/Q-type (3.9%; agatoxin IVA-sensitive), or
both N- and P/Q-type (42.6%) Ca2+ channels, although the remainder of the terminals
(6.1%) were insensitive to these two toxins. In this preparation, two mGluRs with
high and low affinity for L(+)-2-amino-4-phosphonobutyrate were identified by
immunocytochemistry as mGluR4 and mGluR7, respectively. These receptors were responsible
for 22.2 and 24.1% reduction of glutamate release, and they reduced the Ca2+ response
in 24.4 and 30.3% of the nerve terminals, respectively. Interestingly, mGluR4
was largely (73.7%) located in nerve terminals expressing both N- and P/Q-type
Ca2+ channels, whereas mGluR7 was predominantly (69.9%) located in N-type Ca2+
channel-expressing terminals. This specific coexpression of different group III
mGluRs and Ca2+ channels may endow synaptic terminals with distinct release properties
and reveals the existence of a high degree of presynaptic heterogeneity.

text: To understand the possible contribution of metabotropic γ-aminobutyric acid
receptors (GABABR) in cortical development, we investigated the expression pattern
and the cellular and subcellular localization of the GABABR1 and GABABR2 subtypes
in the rat neocortex from embryonic day 14 (E14) to adulthood. At the light microscopic
level, both GABABR1 and GABABR2 were detected as early as E14. During prenatal
development, both subtypes were expressed highly in the cortical plate. Using
double immunofluorescence, GABABR1 colocalized with GABABR2 in neurons of the
marginal zone and subplate, indicating that these proteins are coexpressed and
could be forming functional GABABRs during prenatal development in vivo. In contrast,
only GABABR1 but not GABABR2 was detected in the tangentially migratory cells
in the lower intermediate zone. During postnatal development, immunoreactivity
for GABABR1 and GABABR2 was distributed mainly in pyramidal cells. Discrete GABABR1-immunopositive
cell bodies of interneurons were present throughout the neocortex. In addition,
GABABR1 but not GABABR2 was found in identified Cajal-Retzius cells in layer I.
At the electron microscopic level, immunoreactivity for GABABR1 and GABABR2 was
found in dendritic spines and dendritic shafts at extrasynaptic and perisynaptic
sites throughout postnatal development. We further demonstrated the presynaptic
localization of GABABR1 and GABABR2, as well as the association of the receptors
with asymmetrical synaptic junctions. These results indicate potentially important
roles for the GABABRs in the regulation of migratory processes during corticogenesis
and in the modulation of synaptic transmission during early development of cortical
circuitry.
