  text: 'Vaidman, in a recent article adopts the method of ''quantum weak measurements
    in pre- and postselected ensembles'' to ascertain whether or not the chained-Zeno
    counterfactual computation scheme proposed by Hosten et al. is counterfactual;
    which has been the topic of a debate on the definition of counterfactuality. We
    disagree with his conclusion, which brings up some interesting aspects of quantum
    weak measurements and some concerns about the way they are interpreted. '

  text: Visible light photon counters (VLPCs) and solid-state photomultipliers (SSPMs)
    are high-efficiency single-photon detectors which have multi-photon counting capability.
    While both the VLPCs and the SSPMs have inferred internal quantum efficiencies
    above 93%, the actual measured values for both the detectors were in fact limited
    to less than 88%, attributed to in-coupling losses. We are currently improving
    this overall detection efficiency via a) custom anti-reflection coating the detectors
    and the in-coupling fibers, b) implementing a novel cryogenic design to reduce
    transmission losses and, c) using low-noise electronics to obtain a better signal-to-noise
    ratio.

  text: A source of single photons allows secure quantum key distribution, in addition,
    to being a critical resource for linear optics quantum computing. We describe
    our progress on deterministically creating single photons from spontaneous parametric
    downconversion, an extension of the Pittman, Jacobs and Franson scheme [Phys.
    Rev A, v66, 042303 (2002)]. Their idea was to conditionally prepare single photons
    by measuring one member of a spontaneously emitted photon pair and storing the
    remaining conditionally prepared photon until a predetermined time, when it would
    be &quot;deterministically&quot; released from storage. Our approach attempts
    to improve upon this by recycling the pump pulse in order to decrease the possibility
    of multiple-pair generation, while maintaining a high probability of producing
    a single pair. Many of the challenges we discuss are central to other quantum
    information technologies, including the need for low-loss optical storage, switching
    and detection, and fast feed-forward control.

  text: 'The logic underlying the coherent nature of quantum information processing
    often deviates from intuitive reasoning, leading to surprising effects. Counterfactual
    computation constitutes a striking example: the potential outcome of a quantum
    computation can be inferred, even if the computer is not run 1. Relying on similar
    arguments to interaction-free measurements 2 (or quantum interrogation3), counterfactual
    computation is accomplished by putting the computer in a superposition of ''running''
    and ''not running'' states, and then interfering the two histories. Conditional
    on the as-yet-unknown outcome of the computation, it is sometimes possible to
    counterfactually infer information about the solution. Here we demonstrate counterfactual
    computation, implementing Grover''s search algorithm with an all-optical approach4.
    It was believed that the overall probability of such counterfactual inference
    is intrinsically limited1,5, so that it could not perform better on average than
    random guesses. However, using a novel ''chained'' version of the quantum Zeno
    effect6, we show how to boost the counterfactual inference probability to unity,
    thereby beating the random guessing limit. Our methods are general and apply to
    any physical system, as illustrated by a discussion of trapped-ion systems. Finally,
    we briefly show that, in certain circumstances, counterfactual computation can
    eliminate errors induced by decoherence. '

  text: Although the X chromosome is usually similar to the autosomes in size and
    cytogenetic appearance, theoretical models predict that its hemizygosity in males
    may cause unusual patterns of evolution. The sequencing of several genomes has
    indeed revealed differences between the X chromosome and the autosomes in the
    rates of gene divergence, patterns of gene expression and rates of gene movement
    between chromosomes. A better understanding of these patterns should provide valuable
    information on the evolution of genes located on the X chromosome. It could also
    suggest solutions to more general problems in molecular evolution, such as detecting
    selection and estimating mutational effects on fitness

    We present an adaptive animation method for electrical discharges. Electrical discharges can be simulated using the dielectric breakdown model. Regular discretization of the governing Laplace equation leads to huge equation systems, and the computational cost of solving the equations quickly becomes prohibitive at high resolutions, especially for simulations in 3D. In contrast, our method discretizes the Laplace equation on an adaptive octree, reducing the size of the problem significantly, and making simulations of high resolution 3D datasets and even 3D animations feasible. In order to enhance realism for lightning animations, we propose a particle simulation that animates the residual positive charge. Thus, interaction of electrical discharges with their surroundings
    can be simulated.

  text: Systems of three interacting particles are notorious for their complex physical
    behaviour. A landmark theoretical result in few-body quantum physics is Efimov\'s
    prediction1,2 of a universal set of bound trimer states appearing for three identical
    bosons with a resonant two-body interaction. Counterintuitively, these states
    even exist in the absence of a corresponding two-body bound state. Since the formulation
    of Efimov\'s problem in the context of nuclear physics 35 years ago, it has attracted
    great interest in many areas of physics3-8. However, the observation of Efimov
    quantum states has remained an elusive goal3,5. Here we report the observation
    of an Efimov resonance in an ultracold gas of caesium atoms. The resonance occurs
    in the range of large negative two-body scattering lengths, arising from the coupling
    of three free atoms to an Efimov trimer. Experimentally, we observe its signature
    as a giant three-body recombination loss9,10 when the strength of the two-body
    interaction is varied. We also detect a minimum 9,11,12 in the recombination loss
    for positive scattering lengths, indicating destructive interference of decay
    pathways. Our results confirm central theoretical predictions of Efimov physics
    and represent a starting point with which to explore the universal properties
    of resonantly interacting few-body systems7. While Feshbach resonances13,14 have
    provided the key to control quantum-mechanical interactions on the two-body level,
    Efimov resonances connect ultracold matter15 to the world of few-body quantum
    phenomena.

  text: Three interacting particles form a system which is well known for its complex
    physical behavior. A landmark theoretical result in few-body quantum physics is
    Efimov\'s prediction of a universal set of weakly bound trimer states appearing
    for three identical bosons with a resonant two-body interaction [1, 2]. Surprisingly,
    these states even exist in the absence of a corresponding two-body bound state
    and their precise nature is largely independent of the particular type of the
    two-body interaction potential. Efimov\'s scenario has attracted great interest
    in many areas of physics; an experimental test however has not been achieved.
    We report the observation of an Efimov resonance in an ultracold thermal gas of
    cesium atoms [3]. The resonance occurs in the range of large negative two-body
    scattering lengths and arises from the coupling of three free atoms to an Efimov
    trimer. We observe its signature as a giant three-body recombination loss when
    the strength of the two-body interaction is varied near a Feshbach resonance.
    This resonance develops into a continuum resonance at non-zero collision energies,
    and we observe a shift of the resonance position as a function of temperature.
    We also report on a minimum in the recombination loss for positive scattering
    lengths, indicating destructive interference of decay pathways. Our results confirm
    central theoretical predictions of Efimov physics and represent a starting point
    from which to explore the universal properties of resonantly interacting few-body
    systems.

  text: We demonstrate for different protein samples that three-dimensional HNCO and
    HNCA correlation spectra may be recorded in a few minutes acquisition time using
    the band-selective excitation short-transient sequences presented here. This opens
    new perspectives for the NMR structural investigation of unstable protein samples
    and real-time site-resolved studies of protein kinetics.

  text: Structure elucidation of proteins by either NMR or X‐ray crystallography often
    requires the screening of a large number of samples for promising protein constructs
    and optimum solution conditions. For large‐scale screening of protein samples
    in solution, robust methods are needed that allow a rapid assessment of the folding
    of a polypeptide under diverse sample conditions. Here we present HET‐SOFAST NMR,
    a highly sensitive new method for semi‐quantitative characterization of the structural
    compactness and heterogeneity of polypeptide chains in solution. On the basis
    of one‐dimensional 1H HET‐SOFAST NMR data, obtained on well‐folded, molten globular,
    partially‐ and completely unfolded proteins, we define empirical thresholds that
    can be used as quantitative benchmarks for protein compactness. For 15N‐enriched
    protein samples, two‐dimensional 1H‐15N HET‐SOFAST correlation spectra provide
    site‐specific information about the structural heterogeneity along the polypeptide
    chain.

  text: We demonstrate the feasibility of recording 1H–15N correlation spectra of
    proteins in only one second of acquisition time. The experiment combines recently
    proposed SOFAST-HMQC with Hadamard-type 15N frequency encoding. This allows site-resolved
    real-time NMR studies of kinetic processes in proteins with an increased time
    resolution. The sensitivity of the experiment is sufficient to be applicable to
    a wide range of molecular systems available at millimolar concentration on a high
    magnetic field spectrometer.

  text: We study the extent to which the Hausdorff dimension of a compact subset of
    an infinite-dimensional Banach space is affected by a typical mapping into a finite-dimensional
    space. It is possible that the dimension drops under all such mappings, but the
    amount by which it typically drops is controlled by the ‘thickness exponent’ of
    the set, which was defined by Hunt and Kaloshin (Nonlinearity12 (1999), 1263–1275).
    More precisely, let $X$ be a compact subset of a Banach space $B$ with thickness
    exponent $\tau$ and Hausdorff dimension $d$. Let $M$ be any subspace of the (locally)
    Lipschitz functions from $B$ to $\mathbb{R}^{m}$ that contains the space of bounded
    linear functions. We prove that for almost every (in the sense of prevalence)
    function $f \in M$, the Hausdorff dimension of $f(X)$ is at least $\min\{ m, d
    / (1 + \tau) \}$. We also prove an analogous result for a certain part of the
    dimension spectra of Borel probability measures supported on $X$. The factor $1
    / (1 + \tau)$ can be improved to $1 / (1 + \tau / 2)$ if $B$ is a Hilbert space.
    Since dimension cannot increase under a (locally) Lipschitz function, these theorems
    become dimension preservation results when $\tau = 0$. We conjecture that many
    of the attractors associated with the evolution equations of mathematical physics
    have thickness exponent zero. We also discuss the sharpness of our results in
    the case $\tau > 0$.

  text: "We consider the evolution of a set carried by a space periodic incompressible
    stochastic flow in a Euclidean space. We\r\nreport on three main results obtained
    in [8, 9, 10] concerning long time behaviour for a typical realization of the
    stochastic flow. First, at time t most of the particles are at a distance of order
    √t away from the origin. Moreover, we prove a Central Limit Theorem for the evolution
    of a measure carried by the flow, which holds for almost every realization of
    the flow. Second, we show the existence of a zero measure full Hausdorff dimension
    set of points, which\r\nescape to infinity at a linear rate. Third, in the 2-dimensional
    case, we study the set of points visited by the original set by time t. Such a
    set, when scaled down by the factor of t, has a limiting non random shape."

  text: Phylogenetic relationships between the extinct woolly mammoth (Mammuthus primigenius),
    and the Asian (Elephas maximus) and African savanna (Loxodonta africana) elephants
    remain unresolved. Here, we report the sequence of the complete mitochondrial
    genome (16,842 base pairs) of a woolly mammoth extracted from permafrost-preserved
    remains from the Pleistocene epoch - the oldest mitochondrial genome sequence
    determined to date. We demonstrate that well-preserved mitochondrial genome fragments,
    as long as ∼1,600-1700 base pairs, can be retrieved from pre-Holocene remains
    of an extinct species. Phylogenetic reconstruction of the Elephantinae clade suggests
    that M. primigenius and E. maximus are sister species that diverged soon after
    their common ancestor split from the L. africana lineage. Low nucleotide diversity
    found between independently determined mitochondrial genomic sequences of woolly
    mammoths separated geographically and in time suggests that north-eastern Siberia
    was occupied by a relatively homogeneous population of M. primigenius throughout
    the late Pleistocene.

  text: 'Background: The glyoxylate cycle is thought to be present in bacteria, protists,
    plants, fungi, and nematodes, but not in other Metazoa. However, activity of the
    glyoxylate cycle enzymes, malate synthase (MS) and isocitrate lyase (ICL), in
    animal tissues has been reported. In order to clarify the status of the MS and
    ICL genes in animals and get an insight into their evolution, we undertook a comparative-genomic
    study. Results: Using sequence similarity searches, we identified MS genes in
    arthropods, echinoderms, and vertebrates, including platypus and opossum, but
    not in the numerous sequenced genomes of placental mammals. The regions of the
    placental mammals'' genomes expected to code for malate synthase, as determined
    by comparison of the gene orders in vertebrate genomes, show clear similarity
    to the opossum MS sequence but contain stop codons, indicating that the MS gene
    became a pseudogene in placental mammals. By contrast, the ICL gene is undetectable
    in animals other than the nematodes that possess a bifunctional, fused ICL-MS
    gene. Examination of phylogenetic trees of MS and ICL suggests multiple horizontal
    gene transfer events that probably went in both directions between several bacterial
    and eukaryotic lineages. The strongest evidence was obtained for the acquisition
    of the bifunctional ICL-MS gene from an as yet unknown bacterial source with the
    corresponding operonic organization by the common ancestor of the nematodes. Conclusion:
    The distribution of the MS and ICL genes in animals suggests that either they
    encode alternative enzymes of the glyoxylate cycle that are not orthologous to
    the known MS and ICL or the animal MS acquired a new function that remains to
    be characterized. Regardless of the ultimate solution to this conundrum, the genes
    for the glyoxylate cycle enzymes present a remarkable variety of evolutionary
    events including unusual horizontal gene transfer from bacteria to animals.'

  of non- orthologous gene displacement in glyoxylate cycle specific enzymes and for

  text: The impact of synonymous nucleotide substitutions on fitness in mammals remains
    controversial. Despite some indications of selective constraint, synonymous sites
    are often assumed to be neutral, and the rate of their evolution is used as a
    proxy for mutation rate. We subdivide all sites into four classes in terms of
    the mutable CpG context, nonCpG, postC, preG, and postCpreG, and compare four-fold
    synonymous sites and intron sites residing outside transposable elements. The
    distribution of the rate of evolution across all synonymous sites is trimodal.
    Rate of evolution at nonCpG synonymous sites, not preceded by C and not followed
    by G, is ∼10% below that at such intron sites. In contrast, rate of evolution
    at postCpreG synonymous sites is ∼30% above that at such intron sites. Finally,
    synonymous and intron postC and preG sites evolve at similar rates. The relationship
    between the levels of polymorphism at the corresponding synonymous and intron
    sites is very similar to that between their rates of evolution. Within every class,
    synonymous sites are occupied by G or C much more often than intron sites, whose
    nucleotide composition is consistent with neutral mutation-drift equilibrium.
    These patterns suggest that synonymous sites are under weak selection in favor
    of G and C, with the average coefficient s∼0.25/Ne∼10-5, where Ne is the effective
    population size. Such selection decelerates evolution and reduces variability
    at sites with symmetric mutation, but has the opposite effects at sites where
    the favored nucleotides are more mutable. The amino-acid composition of proteins
    dictates that many synonymous sites are CpGprone, which causes them, on average,
    to evolve faster and to be more polymorphic than intron sites. An average genotype
    carries ∼107 suboptimal nucleotides at synonymous sites, implying synergistic
    epistasis in selection against them.
