  text: Particles in a perfect lattice potential perform Bloch oscillations when subject
    to a constant force, leading to localization and preventing conductivity. For
    a weakly interacting Bose-Einstein condensate of Cs atoms, we observe giant center-of-mass
    oscillations in position space with a displacement across hundreds of lattice
    sites when we add a periodic modulation to the force near the Bloch frequency.
    We study the dependence of these &quot;super&quot; Bloch oscillations on lattice
    depth, modulation amplitude, and modulation frequency and show that they provide
    a means to induce linear transport in a dissipation-free lattice.

  text: Quantum many-body systems can have phase transitions even at zero temperature;
    fluctuations arising from Heisenbergĝ€™s uncertainty principle, as opposed to
    thermal effects, drive the system from one phase to another. Typically, during
    the transition the relative strength of two competing terms in the systemĝ€™s
    Hamiltonian changes across a finite critical value. A well-known example is the
    Mottĝ€&quot; Hubbard quantum phase transition from a superfluid to an insulating
    phase, which has been observed for weakly interacting bosonic atomic gases. However,
    for strongly interacting quantum systems confined to lower-dimensional geometry,
    a novel type of quantum phase transition may be induced and driven by an arbitrarily
    weak perturbation to the Hamiltonian. Here we observe such an effectĝ€&quot;the
    sineĝ€&quot;Gordon quantum phase transition from a superfluid Luttinger liquid
    to a Mott insulatorĝ€ &quot;in a one-dimensional quantum gas of bosonic caesium
    atoms with tunable interactions. For sufficiently strong interactions, the transition
    is induced by adding an arbitrarily weak optical lattice commensurate with the
    atomic granularity, which leads to immediate pinning of the atoms. We map out
    the phase diagram and find that our measurements in the strongly interacting regime
    agree well with a quantum field description based on the exactly solvable sineĝ€&quot;Gordon
    model. We trace the phase boundary all the way to the weakly interacting regime,
    where we find good agreement with the predictions of the one-dimensional Boseĝ€&quot;Hubbard
    model. Our results open up the experimental study of quantum phase transitions,
    criticality and transport phenomena beyond Hubbard-type models in the context
    of ultracold gases.

  text: 'Cytosine methylation silences transposable elements in plants, vertebrates,
    and fungi but also regulates gene expression. Plant methylation is catalyzed by
    three families of enzymes, each with a preferred sequence context: CG, CHG (H
    = A, C, or T), and CHH, with CHH methylation targeted by the RNAi pathway. Arabidopsis
    thaliana endosperm, a placenta-like tissue that nourishes the embryo, is globally
    hypomethylated in the CG context while retaining high non-CG methylation. Global
    methylation dynamics in seeds of cereal crops that provide the bulk of human nutrition
    remain unknown. Here, we show that rice endosperm DNA is hypomethylated in all
    sequence contexts. Non-CG methylation is reduced evenly across the genome, whereas
    CG hypomethylation is localized. CHH methylation of small transposable elements
    is increased in embryos, suggesting that endosperm demethylation enhances transposon
    silencing. Genes preferentially expressed in endosperm, including those coding
    for major storage proteins and starch synthesizing enzymes, are frequently hypomethylated
    in endosperm, indicating that DNA methylation is a crucial regulator of rice endosperm
    biogenesis. Our data show that genome-wide reshaping of seed DNA methylation is
    conserved among angiosperms and has a profound effect on gene expression in cereal
    crops.'

  text: These are notes for a set of 7 two-hour lectures given at the 2010 Summer
    School on Quantitative Evolutionary and Comparative Genomics at OIST, Okinawa,
    Japan. The emphasis is on understanding how biological systems process information.
    We take a physicist's approach of looking for simple phenomenological descriptions
    that can address the questions of biological function without necessarily modeling
    all (mostly unknown) microscopic details; the example that is developed throughout
    the notes is transcriptional regulation in genetic regulatory networks. We present
    tools from information theory and statistical physics that can be used to analyze
    noisy nonlinear biological networks, and build generative and predictive models
    of regulatory processes.

  text: How seizures start is a major question in epilepsy research. Preictal EEG
    changes occur in both human patients and animal models, but their underlying mechanisms
    and relationship with seizure initiation remain unknown. Here we demonstrate the
    existence, in the hippocampal CA1 region, of a preictal state characterized by
    the progressive and global increase in neuronal activity associated with a widespread
    buildup of low-amplitude high-frequency activity (HFA) (&gt; 100 Hz) and reduction
    in system complexity. HFA is generated by the firing of neurons, mainly pyramidal
    cells, at much lower frequencies. Individual cycles of HFA are generated by the
    near-synchronous (within similar to 5 ms) firing of small numbers of pyramidal
    cells. The presence of HFA in the low-calcium model implicates nonsynaptic synchronization;
    the presence of very similar HFA in the high-potassium model shows that it does
    not depend on an absence of synaptic transmission. Immediately before seizure
    onset, CA1 is in a state of high sensitivity in which weak depolarizing or synchronizing
    perturbations can trigger seizures. Transition to seizure is characterized by
    a rapid expansion and fusion of the neuronal populations responsible for HFA,
    associated with a progressive slowing of HFA, leading to a single, massive, hypersynchronous
    cluster generating the high-amplitude low-frequency activity of the seizure.

  text: The induction of a signaling pathway is characterized by transient complex
    formation and mutual posttranslational modification of proteins. To faithfully
    capture this combinatorial process in a math- ematical model is an important challenge
    in systems biology. Exploiting the limited context on which most binding and modification
    events are conditioned, attempts have been made to reduce the com- binatorial
    complexity by quotienting the reachable set of molecular species, into species
    aggregates while preserving the deterministic semantics of the thermodynamic limit.
    Recently we proposed a quotienting that also preserves the stochastic semantics
    and that is complete in the sense that the semantics of individual species can
    be recovered from the aggregate semantics. In this paper we prove that this quotienting
    yields a sufficient condition for weak lumpability and that it gives rise to a
    backward Markov bisimulation between the original and aggregated transition system.
    We illustrate the framework on a case study of the EGF/insulin receptor crosstalk.

  text: These are notes for a set of 7 two-hour lectures given at the 2010 Summer
    School on Quantitative Evolutionary and Comparative Genomics at OIST, Okinawa,
    Japan. The emphasis is on understanding how biological systems process information.
    We take a physicist's approach of looking for simple phenomenological descriptions
    that can address the questions of biological function without necessarily modeling
    all (mostly unknown) microscopic details; the example that is developed throughout
    the notes is transcriptional regulation in genetic regulatory networks. We present
    tools from information theory and statistical physics that can be used to analyze
    noisy nonlinear biological networks, and build generative and predictive models
    of regulatory processes.

  text: The chemotaxis signalling network in Escherichia coli that controls the locomotion
    of bacteria is a classic model system for signal transduction1, 2. This pathway
    modulates the behaviour of flagellar motors to propel bacteria towards sources
    of chemical attractants. Although this system relaxes to a steady state in response
    to environmental changes, the signalling events within the chemotaxis network
    are noisy and cause large temporal variations of the motor behaviour even in the
    absence of stimulus3. That the same signalling network governs both behavioural
    variability and cellular response raises the question of whether these two traits
    are independent. Here, we experimentally establish a fluctuation–response relationship
    in the chemotaxis system of living bacteria. Using this relationship, we demonstrate
    the possibility of inferring the cellular response from the behavioural variability
    measured before stimulus. In monitoring the pre- and post-stimulus switching behaviour
    of individual bacterial motors, we found that variability scales linearly with
    the response time for different functioning states of the cell. This study highlights
    that the fundamental relationship between fluctuation and response is not constrained
    to physical systems at thermodynamic equilibrium4 but is extensible to living
    cells5. Such a relationship not only implies that behavioural variability and
    cellular response can be coupled traits, but it also provides a general framework
    within which we can examine how the selection of a network design shapes this
    interdependence

  text: 'In E. coli, chemotactic behavior exhibits perfect adaptation that is robust
    to changes in the intracellular concentration of the chemotactic proteins, such
    as CheR and CheB. However, the robustness of the perfect adaptation does not explicitly
    imply a robust chemotactic response. Previous studies on the robustness of the
    chemotactic response relied on swarming assays, which can be confounded by processes
    besides chemotaxis, such as cellular growth and depletion of nutrients. Here,
    using a high-throughput capillary assay that eliminates the effects of growth,
    we experimentally studied how the chemotactic response depends on the relative
    concentration of the chemotactic proteins. We simultaneously measured both the
    chemotactic response of E. coli cells to L: -aspartate and the concentrations
    of YFP-CheR and CheB-CFP fusion proteins. We found that the chemotactic response
    is fine-tuned to a specific ratio of [CheR]/[CheB] with a maximum response comparable
    to the chemotactic response of wild-type behavior. In contrast to adaptation in
    chemotaxis, that is robust and exact, capillary assays revealed that the chemotactic
    response in swimming bacteria is fined-tuned to wild-type level of the [CheR]/[CheB]
    ratio.'

  text: If distinct biological species are to coexist in sympatry, they must be reproductively
    isolated and must exploit different limiting resources. A two-niche Levene model
    is analysed, in which habitat preference and survival depend on underlying additive
    traits. The population genetics of preference and viability are equivalent. However,
    there is a linear trade-off between the chances of settling in either niche, whereas
    viabilities may be constrained arbitrarily. With a convex trade-off, a sexual
    population evolves a single generalist genotype, whereas with a concave trade-off,
    disruptive selection favours maximal variance. A pure habitat preference evolves
    to global linkage equilibrium if mating occurs in a single pool, but remarkably,
    evolves to pairwise linkage equilibrium within niches if mating is within those
    niches--independent of the genetics. With a concave trade-off, the population
    shifts sharply between a unimodal distribution with high gene flow and a bimodal
    distribution with strong isolation, as the underlying genetic variance increases.
    However, these alternative states are only simultaneously stable for a narrow
    parameter range. A sharp threshold is only seen if survival in the 'wrong' niche
    is low; otherwise, strong isolation is impossible. Gene flow from divergent demes
    makes speciation much easier in parapatry than in sympatry.

  text: 'The prevalence of recombination in eukaryotes poses one of the most puzzling
    questions in biology. The most compelling general explanation is that recombination
    facilitates selection by breaking down the negative associations generated by
    random drift (i.e. Hill-Robertson interference, HRI). I classify the effects of
    HRI owing to: deleterious mutation, balancing selection and selective sweeps on:
    neutral diversity, rates of adaptation and the mutation load. These effects are
    mediated primarily by the density of deleterious mutations and of selective sweeps.
    Sequence polymorphism and divergence suggest that these rates may be high enough
    to cause significant interference even in genomic regions of high recombination.
    However, neither seems able to generate enough variance in fitness to select strongly
    for high rates of recombination. It is plausible that spatial and temporal fluctuations
    in selection generate much more fitness variance, and hence selection for recombination,
    than can be explained by uniformly deleterious mutations or species-wide selective
    sweeps.'

  text: 'Under the classical view, selection depends more or less directly on mutation:
    standing genetic variance is maintained by a balance between selection and mutation,
    and adaptation is fuelled by new favourable mutations. Recombination is favoured
    if it breaks negative associations among selected alleles, which interfere with
    adaptation. Such associations may be generated by negative epistasis, or by random
    drift (leading to the Hill-Robertson effect). Both deterministic and stochastic
    explanations depend primarily on the genomic mutation rate, U. This may be large
    enough to explain high recombination rates in some organisms, but seems unlikely
    to be so in general. Random drift is a more general source of negative linkage
    disequilibria, and can cause selection for recombination even in large populations,
    through the chance loss of new favourable mutations. The rate of species-wide
    substitutions is much too low to drive this mechanism, but local fluctuations
    in selection, combined with gene flow, may suffice. These arguments are illustrated
    by comparing the interaction between good and bad mutations at unlinked loci under
    the infinitesimal model.'

  text: Crosses between closely related species give two contrasting results. One
    result is that species hybrids may be inferior to their parents, for example,
    being less fertile [1]. The other is that F1 hybrids may display superior performance
    (heterosis), for example with increased vigour [2]. Although various hypotheses
    have been proposed to account for these two aspects of hybridisation, their biological
    basis is still poorly understood [3]. To gain further insights into this issue,
    we analysed the role that variation in gene expression may play. We took a conserved
    trait, flower asymmetry in Antirrhinum, and determined the extent to which the
    underlying regulatory genes varied in expression among closely related species.
    We show that expression of both genes analysed, CYC and RAD, varies significantly
    between species because of cis-acting differences. By making a quantitative genotype-phenotype
    map, using a range of mutant alleles, we demonstrate that the species lie on a
    plateau in gene expression-morphology space, so that the variation has no detectable
    phenotypic effect. However, phenotypic differences can be revealed by shifting
    genotypes off the plateau through genetic crosses. Our results can be readily
    explained if genomes are free to evolve within an effectively neutral zone in
    gene expression space. The consequences of this drift will be negligible for individual
    loci, but when multiple loci across the genome are considered, we show that the
    variation may have significant effects on phenotype and fitness, causing a significant
    drift load. By considering these consequences for various gene-expression-fitness
    landscapes, we conclude that F1 hybrids might be expected to show increased performance
    with regard to conserved traits, such as basic physiology, but reduced performance
    with regard to others. Thus, our study provides a new way of explaining how various
    aspects of hybrid performance may arise through natural variation in gene activity.

  text: DNA samples were extracted from ethanol and formalin-fixed decapod crustacean
    tissue using a new method based on Tetramethylsilane (TMS)-Chelex. It is shown
    that neither an indigestible matrix of cross-linked protein nor soluble PCR inhibitors
    impede PCR success when dealing with formalin-fixed material. Instead, amplification
    success from formalin-fixed tissue appears to depend on the presence of unmodified
    DNA in the extracted sample. A staining method that facilitates the targeting
    of samples with a high content of unmodified DNA is provided.

  text: Cell shape and motility are primarily controlled by cellular mechanics. The
    attachment of the plasma membrane to the underlying actomyosin cortex has been
    proposed to be important for cellular processes involving membrane deformation.
    However, little is known about the actual function of membrane-to-cortex attachment
    (MCA) in cell protrusion formation and migration, in particular in the context
    of the developing embryo. Here, we use a multidisciplinary approach to study MCA
    in zebrafish mesoderm and endoderm (mesendoderm) germ layer progenitor cells,
    which migrate using a combination of different protrusion types, namely, lamellipodia,
    filopodia, and blebs, during zebrafish gastrulation. By interfering with the activity
    of molecules linking the cortex to the membrane and measuring resulting changes
    in MCA by atomic force microscopy, we show that reducing MCA in mesendoderm progenitors
    increases the proportion of cellular blebs and reduces the directionality of cell
    migration. We propose that MCA is a key parameter controlling the relative proportions
    of different cell protrusion types in mesendoderm progenitors, and thus is key
    in controlling directed migration during gastrulation.

  text: "Recent progress in per-pixel object class labeling of natural images can
    be attributed to the use of multiple types of image features and sound statistical
    learning approaches. Within the latter, Conditional Random Fields (CRF) are prominently
    used for their ability to represent interactions between random variables. Despite
    their popularity in computer vision, parameter learning for CRFs has remained
    difficult, popular approaches being cross-validation and piecewise training.\r\nIn
    this work, we propose a simple yet expressive tree-structured CRF based on a recent
    hierarchical image segmentation method. Our model combines and weights multiple
    image features within a hierarchical representation and allows simple and efficient
    globally-optimal learning of ≈ 105 parameters. The tractability of our model allows
    us to pose and answer some of the open questions regarding parameter learning
    applying to CRF-based approaches. The key findings for learning CRF models are,
    from the obvious to the surprising, i) multiple image features always help, ii)
    the limiting dimension with respect to current models is the amount of training
    data, iii) piecewise training is competitive, iv) current methods for max-margin
    training fail for models with many parameters.\r\n"

  text: Fast-spiking, parvalbumin-expressing basket cells (BCs) play a key role in
    feedforward and feedback inhibition in the hippocampus. However, the dendritic
    mechanisms underlying rapid interneuron recruitment have remained unclear. To
    quantitatively address this question, we developed detailed passive cable models
    of BCs in the dentate gyrus based on dual somatic or somatodendritic recordings
    and complete morphologic reconstructions. Both specific membrane capacitance and
    axial resistivity were comparable to those of pyramidal neurons, but the average
    somatodendritic specific membrane resistance (R(m)) was substantially lower in
    BCs. Furthermore, R(m) was markedly nonuniform, being lowest in soma and proximal
    dendrites, intermediate in distal dendrites, and highest in the axon. Thus, the
    somatodendritic gradient of R(m) was the reverse of that in pyramidal neurons.
    Further computational analysis revealed that these unique cable properties accelerate
    the time course of synaptic potentials at the soma in response to fast inputs,
    while boosting the efficacy of slow distal inputs. These properties will facilitate
    both rapid phasic and efficient tonic activation of BCs in hippocampal microcircuits.
