  text: We present a new method for spectral clustering with paired data based on
    kernel canonical correlation analysis, called correlational spectral clustering.
    Paired data are common in real world data sources, such as images with text captions.
    Traditional spectral clustering algorithms either assume that data can be represented
    by a single similarity measure, or by co-occurrence matrices that are then used
    in biclustering. In contrast, the proposed method uses separate similarity measures
    for each data representation, and allows for projection of previously unseen data
    that are only observed in one representation (e.g. images but not text). We show
    that this algorithm generalizes traditional spectral clustering algorithms and
    show consistent empirical improvement over spectral clustering on a variety of
    datasets of images with associated text.

  text: Most successful object recognition systems rely on binary classification,
    deciding only if an object is present or not, but not providing information on
    the actual object location. To perform localization, one can take a sliding window
    approach, but this strongly increases the computational cost, because the classifier
    function has to be evaluated over a large set of candidate subwindows. In this
    paper, we propose a simple yet powerful branchand- bound scheme that allows efficient
    maximization of a large class of classifier functions over all possible subimages.
    It converges to a globally optimal solution typically in sublinear time. We show
    how our method is applicable to different object detection and retrieval scenarios.
    The achieved speedup allows the use of classifiers for localization that formerly
    were considered too slow for this task, such as SVMs with a spatial pyramid kernel
    or nearest neighbor classifiers based on the 2-distance. We demonstrate state-of-the-art
    performance of the resulting systems on the UIUC Cars dataset, the PASCAL VOC
    2006 dataset and in the PASCAL VOC 2007 competition.

    Most current methods for multi-class object classification and localization work as independent 1-vs-rest classifiers. They decide whether and where an object is visible in an image purely on a per-class basis. Joint learning of more than one object class would generally be preferable, since this would allow the use of contextual information such as co-occurrence between classes. However, this approach is usually not employed because of its computational cost.

    In this paper we propose a method to combine the efficiency of single class localization with a subsequent decision process that works jointly for all given object classes. By following a multiple kernel learning (MKL) approach, we automatically obtain a sparse dependency graph of relevant object classes on which to base the decision. Experiments on the PASCAL VOC 2006 and 2007 datasets show that the subsequent joint decision step clearly improves the accuracy compared to single class detection.

  text: Single-molecule atomic force microscopy (AFM) provides novel ways to characterize
    the structure-function relationship of native membrane proteins. High-resolution
    AFM topographs allow observing the structure of single proteins at sub-nanometer
    resolution as well as their conformational changes, oligomeric state, molecular
    dynamics and assembly. We will review these feasibilities illustrating examples
    of membrane proteins in native and reconstituted membranes. Classification of
    individual topographs of single proteins allows understanding the principles of
    motions of their extrinsic domains, to learn about their local structural flexibilities
    and to find the entropy minima of certain conformations. Combined with the visualization
    of functionally related conformational changes these insights allow understanding
    why certain flexibilities are required for the protein to function and how structurally
    flexible regions allow certain conformational changes. Complementary to AFM imaging,
    single-molecule force spectroscopy (SMFS) experiments detect molecular interactions
    established within and between membrane proteins. The sensitivity of this method
    makes it possible to measure interactions that stabilize secondary structures
    such as transmembrane α-helices, polypeptide loops and segments within. Changes
    in temperature or protein-protein assembly do not change the locations of stable
    structural segments, but influence their stability established by collective molecular
    interactions. Such changes alter the probability of proteins to choose a certain
    unfolding pathway. Recent examples have elucidated unfolding and refolding pathways
    of membrane proteins as well as their energy landscapes.

  text: Gene expression levels fluctuate even under constant external conditions.
    Much emphasis has usually been placed on the components of this noise that are
    due to randomness in transcription and translation. Here we focus on the role
    of noise associated with the inputs to transcriptional regulation; in particular,
    we analyze the effects of random arrival times and binding of transcription factors
    to their target sites along the genome. This contribution to the total noise sets
    a fundamental physical limit to the reliability of genetic control, and has clear
    signatures, but we show that these are easily obscured by experimental limitations
    and even by conventional methods for plotting the variance vs. mean expression
    level. We argue that simple, universal models of noise dominated by transcription
    and translation are inconsistent with the embedding of gene expression in a network
    of regulatory interactions. Analysis of recent experiments on transcriptional
    control in the early Drosophila embryo shows that these results are quantitatively
    consistent with the predicted signatures of input noise, and we discuss the experiments
    needed to test the importance of input noise more generally.

  text: 'Changes in a cell''s external or internal conditions are usually reflected
    in the concentrations of the relevant transcription factors. These proteins in
    turn modulate the expression levels of the genes under their control and sometimes
    need to perform nontrivial computations that integrate several inputs and affect
    multiple genes. At the same time, the activities of the regulated genes would
    fluctuate even if the inputs were held fixed, as a consequence of the intrinsic
    noise in the system, and such noise must fundamentally limit the reliability of
    any genetic computation. Here we use information theory to formalize the notion
    of information transmission in simple genetic regulatory elements in the presence
    of physically realistic noise sources. The dependence of this &quot;channel capacity&quot;
    on noise parameters, cooperativity and cost of making signaling molecules is explored
    systematically. We find that, in the range of parameters probed by recent in vivo
    measurements, capacities higher than one bit should be achievable. It is of course
    generally accepted that gene regulatory elements must, in order to function properly,
    have a capacity of at least one bit. The central point of our analysis is the
    demonstration that simple physical models of noisy gene transcription, with realistic
    parameters, can indeed achieve this capacity: it was not self-evident that this
    should be so. We also demonstrate that capacities significantly greater than one
    bit are possible, so that transcriptional regulation need not be limited to simple
    &quot;on-off&quot; components. The question whether real systems actually exploit
    this richer possibility is beyond the scope of this investigation.'

  text: In the simplest view of transcriptional regulation, the expression of a gene
    is turned on or off by changes in the concentration of a transcription factor
    (TF). We use recent data on noise levels in gene expression to show that it should
    be possible to transmit much more than just one regulatory bit. Realizing this
    optimal information capacity would require that the dynamic range of TF concentrations
    used by the cell, the input/output relation of the regulatory module, and the
    noise in gene expression satisfy certain matching relations, which we derive.
    These results provide parameter-free, quantitative predictions connecting independently
    measurable quantities. Although we have considered only the simplified problem
    of a single gene responding to a single TF, we find that these predictions are
    in surprisingly good agreement with recent experiments on the Bicoid/Hunchback
    system in the early Drosophila embryo and that this system achieves approximately
    90% of its theoretical maximum information transmission.

  text: It is widely acknowledged that detailed timing of action potentials is used
    to encode information, for example, in auditory pathways; however, the computational
    tools required to analyze encoding through timing are still in their infancy.
    We present a simple example of encoding, based on a recent model of time-frequency
    analysis, in which units fire action potentials when a certain condition is met,
    but the timing of the action potential depends also on other features of the stimulus.
    We show that, as a result, spike-triggered averages are smoothed so much that
    they do not represent the true features of the encoding. Inspired by this example,
    we present a simple method, differential reverse correlations, that can separate
    an analysis of what causes a neuron to spike, and what controls its timing. We
    analyze with this method the leaky integrate-and-fire neuron and show the method
    accurately reconstructs the model's kernel.

  text: 'Revealing the spectrum of combinatorial regulation of transcription at individual
    promoters is essential for understanding the complex structure of biological networks.
    However, the computations represented by the integration of various molecular
    signals at complex promoters are difficult to decipher in the absence of simple
    cis regulatory codes. Here we synthetically shuffle the regulatory architecture-operator
    sequences binding activators and repressors-of a canonical bacterial promoter.
    The resulting library of complex promoters allows for rapid exploration of promoter
    encoded logic regulation. Among all possible logic functions, NOR and ANDN promoter
    encoded logics predominate. A simple transcriptional cis regulatory code determines
    both logics, establishing a straightforward map between promoter structure and
    logic phenotype. The regulatory code is determined solely by the type of transcriptional
    regulation combinations: two repressors generate a NOR: NOT (a OR b) whereas a
    repressor and an activator generate an ANDN: a AND NOT b. Three-input versions
    of both logics, having an additional repressor as an input, are also present in
    the library. The resulting complex promoters cover a wide dynamic range of transcriptional
    strengths. Synthetic promoter shuffling represents a fast and efficient method
    for exploring the spectrum of complex regulatory functions that can be encoded
    by complex promoters. From an engineering point of view, synthetic promoter shuffling
    enables the experimental testing of the functional properties of complex promoters
    that cannot necessarily be inferred ab initio from the known properties of the
    individual genetic components. Synthetic promoter shuffling may provide a useful
    experimental tool for studying naturally occurring promoter shuffling.'

  text: Fluorescence correlation spectroscopy (FCS) has permitted the characterization
    of high concentrations of noncoding RNAs in a single living bacterium. Here, we
    extend the use of FCS to low concentrations of coding RNAs in single living cells.
    We genetically fuse a red fluorescent protein (RFP) gene and two binding sites
    for an RNA-binding protein, whose translated product is the RFP protein alone.
    Using this construct, we determine in single cells both the absolute [mRNA] concentration
    and the associated [RFP] expressed from an inducible plasmid. We find that the
    FCS method allows us to reliably monitor in real-time [mRNA] down to similar to
    40 nM (i.e. approximately two transcripts per volume of detection). To validate
    these measurements, we show that [mRNA] is proportional to the associated expression
    of the RFP protein. This FCS-based technique establishes a framework for minimally
    invasive measurements of mRNA concentration in individual living bacteria.

  text: We introduce a method for efficiently animating a wide range of deformable
    materials. We combine a high resolution surface mesh with a tetrahedral finite
    element simulator that makes use of frequent re-meshing. This combination allows
    for fast and detailed simulations of complex elastic and plastic behavior. We
    significantly expand the range of physical parameters that can be simulated with
    a single technique, and the results are free from common artifacts such as volume-loss,
    smoothing, popping, and the absence of thin features like strands and sheets.
    Our decision to couple a high resolution surface with low-resolution physics leads
    to efficient simulation and detailed surface features, and our approach to creating
    the tetrahedral mesh leads to an order-of-magnitude speedup over previous techniques
    in the time spent re-meshing. We compute masses, collisions, and surface tension
    forces on the scale of the fine mesh, which helps avoid visual artifacts due to
    the differing mesh resolutions. The result is a method that can simulate a large
    array of different material behaviors with high resolution features in a short
    amount of time.

  text: The geometrical representation of the space of phylogenetic trees implies
    a metric on the space of weighted trees. This metric, the geodesic distance, is
    the length of the shortest path through that space. We present an exact algorithm
    to compute this metric. For biologically reasonable trees, the implementation
    allows fast computations of the geodesic distance, although the running time of
    the algorithm is worst-case exponential. The algorithm was applied to pairs of
    118 gene trees of the metazoa. The results show that a special path in tree space,
    the cone path, which can be computed in linear time, is a good approximation of
    the geodesic distance. The program GeoMeTree is a python implementation of the
    geodesic distance, and it is approximations and is available from www.cibiv.at/software/geometree.

  text: Dentate gyrus granule cells transmit action potentials (APs) along their unmyelinated
    mossy fibre axons to the CA3 region. Although the initiation and propagation of
    APs are fundamental steps during neural computation, little is known about the
    site of AP initiation and the speed of propagation in mossy fibre axons. To address
    these questions, we performed simultaneous somatic and axonal whole-cell recordings
    from granule cells in acute hippocampal slices of adult mice at approximately
    23 degrees C. Injection of short current pulses or synaptic stimulation evoked
    axonal and somatic APs with similar amplitudes. By contrast, the time course was
    significantly different, as axonal APs had a higher maximal rate of rise (464
    +/- 30 V s(-1) in the axon versus 297 +/- 12 V s(-1) in the soma, mean +/- s.e.m.).
    Furthermore, analysis of latencies between the axonal and somatic signals showed
    that APs were initiated in the proximal axon at approximately 20-30 mum distance
    from the soma, and propagated orthodromically with a velocity of 0.24 m s(-1).
    Qualitatively similar results were obtained at a recording temperature of approximately
    34 degrees C. Modelling of AP propagation in detailed cable models of granule
    cells suggested that a approximately 4 times higher Na(+) channel density ( approximately
    1000 pS mum(-2)) in the axon might account for both the higher rate of rise of
    axonal APs and the robust AP initiation in the proximal mossy fibre axon. This
    may be of critical importance to separate dendritic integration of thousands of
    synaptic inputs from the generation and transmission of a common AP output.

  text: It is generally thought that transmitter release at mammalian central synapses
    is triggered by Ca2+ microdomains, implying loose coupling between presynaptic
    Ca2+ channels and Ca2+ sensors of exocytosis. Here we show that Ca2+ channel subunit
    immunoreactivity is highly concentrated in the active zone of GABAergic presynaptic
    terminals of putative parvalbumin-containing basket cells in the hippocampus.
    Paired recording combined with presynaptic patch pipette perfusion revealed that
    GABA release at basket cell-granule cell synapses is sensitive to millimolar concentrations
    of the fast Ca2+ chelator BAPTA but insensitive to the slow Ca2+ chelator EGTA.
    These results show that Ca2+ source and Ca2+ sensor are tightly coupled at this
    synapse, with distances in the range of 10-20 nm. Models of Ca2+ inflow-exocytosis
    coupling further reveal that the tightness of coupling increases efficacy, speed,
    and temporal precision of transmitter release. Thus, tight coupling contributes
    to fast feedforward and feedback inhibition in the hippocampal network.

  text: Fast-spiking parvalbumin-expressing basket cells (BCs) represent a major type
    of inhibitory interneuron in the hippocampus. These cells inhibit principal cells
    in a temporally precise manner and are involved in the generation of network oscillations.
    Although BCs show a unique expression profile of Ca(2+)-permeable receptors, Ca(2+)-binding
    proteins and Ca(2+)-dependent signalling molecules, physiological Ca(2+) signalling
    in these interneurons has not been investigated. To study action potential (AP)-induced
    dendritic Ca(2+) influx and buffering, we combined whole-cell patch-clamp recordings
    with ratiometric Ca(2+) imaging from the proximal apical dendrites of rigorously
    identified BCs in acute slices, using the high-affinity Ca(2+) indicator fura-2
    or the low-affinity dye fura-FF. Single APs evoked dendritic Ca(2+) transients
    with small amplitude. Bursts of APs evoked Ca(2+) transients with amplitudes that
    increased linearly with AP number. Analysis of Ca(2+) transients under steady-state
    conditions with different fura-2 concentrations and during loading with 200 microm
    fura-2 indicated that the endogenous Ca(2+)-binding ratio was approximately 200
    (kappa(S) = 202 +/- 26 for the loading experiments). The peak amplitude of the
    Ca(2+) transients measured directly with 100 microm fura-FF was 39 nm AP(-1).
    At approximately 23 degrees C, the decay time constant of the Ca(2+) transients
    was 390 ms, corresponding to an extrusion rate of approximately 600 s(-1). At
    34 degrees C, the decay time constant was 203 ms and the corresponding extrusion
    rate was approximately 1100 s(-1). At both temperatures, continuous theta-burst
    activity with three to five APs per theta cycle, as occurs in vivo during exploration,
    led to a moderate increase in the global Ca(2+) concentration that was proportional
    to AP number, whereas more intense stimulation was required to reach micromolar
    Ca(2+) concentrations and to shift Ca(2+) signalling into a non-linear regime.
    In conclusion, dentate gyrus BCs show a high endogenous Ca(2+)-binding ratio,
    a small AP-induced dendritic Ca(2+) influx, and a relatively slow Ca(2+) extrusion.
    These specific buffering properties of BCs will sharpen the time course of local
    Ca(2+) signals, while prolonging the decay of global Ca(2+) signals.

  text: Gamma frequency (30-100 Hz) oscillations in the mature cortex underlie higher
    cognitive functions. Fast signaling in GABAergic interneuron networks plays a
    key role in the generation of these oscillations. During development of the rodent
    brain, gamma activity appears at the end of the first postnatal week, but frequency
    and synchrony reach adult levels only by the fourth week. However, the mechanisms
    underlying the maturation of gamma activity are unclear. Here we demonstrate that
    hippocampal basket cells (BCs), the proposed cellular substrate of gamma oscillations,
    undergo marked changes in their morphological, intrinsic, and synaptic properties
    between postnatal day 6 (P6) and P25. During maturation, action potential duration,
    propagation time, duration of the release period, and decay time constant of IPSCs
    decreases by approximately 30-60%. Thus, postnatal development converts BCs from
    slow into fast signaling devices. Computational analysis reveals that BC networks
    with young intrinsic and synaptic properties as well as reduced connectivity generate
    oscillations with moderate coherence in the lower gamma frequency range. In contrast,
    BC networks with mature properties and increased connectivity generate highly
    coherent activity in the upper gamma frequency band. Thus, late postnatal maturation
    of BCs enhances coherence in neuronal networks and will thereby contribute to
    the development of cognitive brain functions.

  text: Previous studies revealed that synaptotagmin 1 is the major Ca(2+) sensor
    for fast synchronous transmitter release at excitatory synapses. However, the
    molecular identity of the Ca(2+) sensor at hippocampal inhibitory synapses has
    not been determined. To address the functional role of synaptotagmin 1 at identified
    inhibitory terminals, we made paired recordings from synaptically connected basket
    cells (BCs) and granule cells (GCs) in the dentate gyrus in organotypic slice
    cultures from wild-type and synaptotagmin 1-deficient mice. As expected, genetic
    elimination of synaptotagmin 1 abolished synchronous transmitter release at excitatory
    GC-BC synapses. However, synchronous release at inhibitory BC-GC synapses was
    maintained. Quantitative analysis revealed that elimination of synaptotagmin 1
    reduced release probability and depression but maintained the synchrony of transmitter
    release at BC-GC synapses. Elimination of synaptotagmin 1 also increased the frequency
    of both miniature excitatory postsynaptic currents (measured in BCs) and miniature
    inhibitory postsynaptic currents (recorded in GCs), consistent with a clamping
    function of synaptotagmin 1 at both excitatory and inhibitory terminals. Single-cell
    reverse-transcription quantitative PCR analysis revealed that single BCs coexpressed
    multiple synaptotagmin isoforms, including synaptotagmin 1-5, 7, and 11-13. Our
    results indicate that, in contrast to excitatory synapses, synaptotagmin 1 is
    not absolutely required for synchronous release at inhibitory BC-GC synapses.
    Thus, alternative fast Ca(2+) sensors contribute to synchronous release of the
    inhibitory transmitter GABA in cortical circuits.

  text: We survey value iteration algorithms on graphs. Such algorithms can be used
    for determining the existence of certain paths (model checking), the existence
    of certain strategies (game solving), and the probabilities of certain events
    (performance analysis). We classify the algorithms according to the value domain
    (boolean, probabilistic, or quantitative); according to the graph structure (nondeterministic,
    probabilistic, or multi-player); according to the desired property of paths (Borel
    level 1, 2, or 3); and according to the alternation depth and convergence rate
    of fixpoint computations.

  text: We study the controller synthesis problem under budget constraints. In this
    problem, there is a cost associated with making an observation, and a controller
    can make only a limited number of observations in each round so that the total
    cost of the observations does not exceed a given fixed budget. The controller
    must ensure some omega-regular requirement subject to the budget constraint. Budget
    constraints arise in designing and implementing controllers for resource-constrained
    embedded systems, where a controller may not have enough power, time, or bandwidth
    to obtain data from all sensors in each round. They lead to games of imperfect
    information, where the unknown information is not fixed a priori, but can vary
    from round to round, based on the choices made by the controller how to allocate
    its budget. We show that the budget-constrained synthesis problem for W-regular
    objectives is complete for exponential time. In addition to studying synthesis
    under a fixed budget constraint, we study the budget optimization problem, where
    given a plant, an objective, and observation costs, we have to find a controller
    that achieves the objective with minimal average accumulated cost (or minimal
    peak cost). We show that this problem is reducible to a game of imperfect information
    where the winning objective is a conjunction of an omega-regular condition and
    a long-run average condition (or a least max-cost condition), and this again leads
    to an exponential-time algorithm. Finally, we extend our results to games over
    infinite state spaces, and show that the budget-constrained synthesis problem
    is decidable for infinite state games with stable quotients of finite index. Consequently,
    the discrete time budget-constrained synthesis problem is decidable for rectangular
    hybrid automata.
