text: When electron microscopy (EM) was introduced in the 1930s it gave scientists
their first look into the nanoworld of cells. Over the last 80 years EM has vastly
increased our understanding of the complex cellular structures that underlie the
diverse functions that cells need to maintain life. One drawback that has been
difficult to overcome was the inherent lack of volume information, mainly due
to the limit on the thickness of sections that could be viewed in a transmission
electron microscope (TEM). For many years scientists struggled to achieve three-dimensional
(3D) EM using serial section reconstructions, TEM tomography, and scanning EM
(SEM) techniques such as freeze-fracture. Although each technique yielded some
special information, they required a significant amount of time and specialist
expertise to obtain even a very small 3D EM dataset. Almost 20 years ago scientists
began to exploit SEMs to image blocks of embedded tissues and perform serial sectioning
of these tissues inside the SEM chamber. Using first focused ion beams (FIB) and
subsequently robotic ultramicrotomes (serial block-face, SBF-SEM) microscopists
were able to collect large volumes of 3D EM information at resolutions that could
address many important biological questions, and do so in an efficient manner.
We present here some examples of 3D EM taken from the many diverse specimens that
have been imaged in our core facility. We propose that the next major step forward
will be to efficiently correlate functional information obtained using light microscopy
(LM) with 3D EM datasets to more completely investigate the important links between
cell structures and their functions.

text: We investigate the relation between Bose-Einstein condensation (BEC) and superfluidity
in the ground state of a one-dimensional model of interacting bosons in a strong
random potential. We prove rigorously that in a certain parameter regime the superfluid
fraction can be arbitrarily small while complete BEC prevails. In another regime
there is both complete BEC and complete superfluidity, despite the strong disorder

text: We provide a framework for compositional and iterative design and verification
of systems with quantitative information, such as rewards, time or energy. It
is based on disjunctive modal transition systems where we allow actions to bear
various types of quantitative information. Throughout the design process the actions
can be further refined and the information made more precise. We show how to compute
the results of standard operations on the systems, including the quotient (residual),
which has not been previously considered for quantitative non-deterministic systems.
Our quantitative framework has close connections to the modal nu-calculus and
is compositional with respect to general notions of distances between systems
and the standard operations.

text: "We introduce a one-parametric family of tree growth models, in which branching
probabilities decrease with branch age τ as τ-α. Depending on the exponent α,
the scaling of tree depth with tree size n displays a transition between the logarithmic
scaling of random trees and an algebraic growth. At the transition (α=1) tree
depth grows as (logn)2. This anomalous scaling is in good agreement with the trend
observed in evolution of biological species, thus providing a theoretical support
for age-dependent speciation and associating it to the occurrence of a critical
point.\r\n"

text: Petrocoptis is a small genus of chasmophytic plants endemic to the Iberian
Peninsula, with some localized populations in the French Pyrenees. Within the
genus, a dozen species have been recognized based on morphological diversity,
most of them with limited distribution area, in small populations and frequently
with potential threats to their survival. To date, however, a molecular evaluation
of the current systematic treatments has not been carried out. The aim of the
present study is to infer phylogenetic relationships among its subordinate taxa
by using plastidial rps16 intron and nuclear internal transcribed spacer (ITS)
DNA sequences; and evaluate the phylogenetic placement of the genus Petrocoptis
within the family Caryophyllaceae. The monophyly of Petrocoptis is supported by
both ITS and rps16 intron sequence analyses. Furthermore, time estimates using
BEAST analyses indicate a Middle to Late Miocene diversification (10.59 Myr, 6.44–15.26
Myr highest posterior densities [HPD], for ITS; 14.30 Myr, 8.61–21.00 Myr HPD,
for rps16 intron).

text: 'The concept of positional information is central to our understanding of
how cells determine their location in a multicellular structure and thereby their
developmental fates. Nevertheless, positional information has neither been defined
mathematically nor quantified in a principled way. Here we provide an information-theoretic
definition in the context of developmental gene expression patterns and examine
the features of expression patterns that affect positional information quantitatively.
We connect positional information with the concept of positional error and develop
tools to directly measure information and error from experimental data. We illustrate
our framework for the case of gap gene expression patterns in the early Drosophila
embryo and show how information that is distributed among only four genes is sufficient
to determine developmental fates with nearly single-cell resolution. Our approach
can be generalized to a variety of different model systems; procedures and examples
are discussed in detail. '

text: We typically think of cells as responding to external signals independently
by regulating their gene expression levels, yet they often locally exchange information
and coordinate. Can such spatial coupling be of benefit for conveying signals
subject to gene regulatory noise? Here we extend our information-theoretic framework
for gene regulation to spatially extended systems. As an example, we consider
a lattice of nuclei responding to a concentration field of a transcriptional regulator
(the "input") by expressing a single diffusible target gene. When input
concentrations are low, diffusive coupling markedly improves information transmission;
optimal gene activation functions also systematically change. A qualitatively
new regulatory strategy emerges where individual cells respond to the input in
a nearly step-like fashion that is subsequently averaged out by strong diffusion.
While motivated by early patterning events in the Drosophila embryo, our framework
is generically applicable to spatially coupled stochastic gene expression models.

text: 'We numerically investigate the distribution of extrema of ''chaotic'' Laplacian
eigenfunctions on two-dimensional manifolds. Our contribution is two-fold: (a)
we count extrema on grid graphs with a small number of randomly added edges and
show the behavior to coincide with the 1957 prediction of Longuet-Higgins for
the continuous case and (b) we compute the regularity of their spatial distribution
using discrepancy, which is a classical measure from the theory of Monte Carlo
integration. The first part suggests that grid graphs with randomly added edges
should behave like two-dimensional surfaces with ergodic geodesic flow; in the
second part we show that the extrema are more regularly distributed in space than
the grid Z2.'

text: "We present a method and a tool for generating succinct representations of
sets of concurrent traces. We focus on trace sets that contain all correct or
all incorrect permutations of events from a given trace. We represent trace sets
as HB-Formulas that are Boolean combinations of happens-before constraints between
events. To generate a representation of incorrect interleavings, our method iteratively
explores interleavings that violate the specification and gathers generalizations
of the discovered interleavings into an HB-Formula; its complement yields a representation
of correct interleavings.\r\n\r\nWe claim that our trace set representations can
drive diverse verification, fault localization, repair, and synthesis techniques
for concurrent programs. We demonstrate this by using our tool in three case studies
involving synchronization synthesis, bug summarization, and abstraction refinement
based verification. In each case study, our initial experimental results have
been promising.\r\n\r\nIn the first case study, we present an algorithm for inferring
missing synchronization from an HB-Formula representing correct interleavings
of a given trace. The algorithm applies rules to rewrite specific patterns in
the HB-Formula into locks, barriers, and wait-notify constructs. In the second
case study, we use an HB-Formula representing incorrect interleavings for bug
summarization. While the HB-Formula itself is a concise counterexample summary,
we present additional inference rules to help identify specific concurrency bugs
such as data races, define-use order violations, and two-stage access bugs. In
the final case study, we present a novel predicate learning procedure that uses
HB-Formulas representing abstract counterexamples to accelerate counterexample-guided
abstraction refinement (CEGAR). In each iteration of the CEGAR loop, the procedure
refines the abstraction to eliminate multiple spurious abstract counterexamples
drawn from the HB-Formula."

text: We prove that the three-state toric homogeneous Markov chain model has Markov
degree two. In algebraic terminology this means, that a certain class of toric
ideals is generated by quadratic binomials. This was conjectured by Haws, Martin
del Campo, Takemura and Yoshida, who proved that they are generated by degree
six binomials.

text: The paper describes a generalized iterative proportional fitting procedure
that can be used for maximum likelihood estimation in a special class of the general
log-linear model. The models in this class, called relational, apply to multivariate
discrete sample spaces that do not necessarily have a Cartesian product structure
and may not contain an overall effect. When applied to the cell probabilities,
the models without the overall effect are curved exponential families and the
values of the sufficient statistics are reproduced by the MLE only up to a constant
of proportionality. The paper shows that Iterative Proportional Fitting, Generalized
Iterative Scaling, and Improved Iterative Scaling fail to work for such models.
The algorithm proposed here is based on iterated Bregman projections. As a by-product,
estimates of the multiplicative parameters are also obtained. An implementation
of the algorithm is available as an R-package.

text: 'The monotone secant conjecture posits a rich class of polynomial systems,
all of whose solutions are real. These systems come from the Schubert calculus
on flag manifolds, and the monotone secant conjecture is a compelling generalization
of the Shapiro conjecture for Grassmannians (Theorem of Mukhin, Tarasov, and Varchenko).
We present some theoretical evidence for this conjecture, as well as computational
evidence obtained by 1.9 teraHertz-years of computing, and we discuss some of
the phenomena we observed in our data. '

text: The concepts of faithfulness and strong-faithfulness are important for statistical
learning of graphical models. Graphs are not sufficient for describing the association
structure of a discrete distribution. Hypergraphs representing hierarchical log-linear
models are considered instead, and the concept of parametric (strong-) faithfulness
with respect to a hypergraph is introduced. Strong-faithfulness ensures the existence
of uniformly consistent parameter estimators and enables building uniformly consistent
procedures for a hypergraph search. The strength of association in a discrete
distribution can be quantified with various measures, leading to different concepts
of strong-faithfulness. Lower and upper bounds for the proportions of distributions
that do not satisfy strong-faithfulness are computed for different parameterizations
and measures of association.

text: Small GTP-binding proteins of the Ras superfamily play diverse roles in intracellular
trafficking. Among them, the Rab, Arf, and Rho families function in successive
steps of vesicle transport, in forming vesicles from donor membranes, directing
vesicle trafficking toward target membranes and docking vesicles onto target membranes.
These proteins act as molecular switches that are controlled by a cycle of GTP
binding and hydrolysis regulated by guanine nucleotide exchange factors (GEFs)
and GTPase-activating proteins (GAPs). In this study we explored the role of GAPs
in the regulation of the endocytic pathway using fluorescently labeled yeast mating
pheromone α-factor. Among 25 non-essential GAP mutants, we found that deletion
of the GLO3 gene, encoding Arf-GAP protein, caused defective internalization of
fluorescently labeled α-factor. Quantitative analysis revealed that glo3Δ cells
show defective α-factor binding to the cell surface. Interestingly, Ste2p, the
α-factor receptor, was mis-localized from the plasma membrane to the vacuole in
glo3Δ cells. Domain deletion mutants of Glo3p revealed that a GAP-independent
function, as well as the GAP activity, of Glo3p is important for both α-factor
binding and Ste2p localization at the cell surface. Additionally, we found that
deletion of the GLO3 gene affects the size and number of Arf1p-residing Golgi
compartments and causes a defect in transport from the TGN to the plasma membrane.
Furthermore, we demonstrated that glo3Δ cells were defective in the late endosome-to-TGN
transport pathway, but not in the early endosome-to-TGN transport pathway. These
findings suggest novel roles for Arf-GAP Glo3p in endocytic recycling of cell
surface proteins.

text: A hybrid-parallel direct-numerical-simulation method with application to turbulent
Taylor-Couette flow is presented. The Navier-Stokes equations are discretized
in cylindrical coordinates with the spectral Fourier-Galerkin method in the axial
and azimuthal directions, and high-order finite differences in the radial direction.
Time is advanced by a second-order, semi-implicit projection scheme, which requires
the solution of five Helmholtz/Poisson equations, avoids staggered grids and renders
very small slip velocities. Nonlinear terms are evaluated with the pseudospectral
method. The code is parallelized using a hybrid MPI-OpenMP strategy, which, compared
with a flat MPI parallelization, is simpler to implement, allows to reduce inter-node
communications and MPI overhead that become relevant at high processor-core counts,
and helps to contain the memory footprint. A strong scaling study shows that the
hybrid code maintains scalability up to more than 20,000 processor cores and thus
allows to perform simulations at higher resolutions than previously feasible.
In particular, it opens up the possibility to simulate turbulent Taylor-Couette
flows at Reynolds numbers up to O(105). This enables to probe hydrodynamic turbulence
in Keplerian flows in experimentally relevant regimes.

text: "Considering a continuous self-map and the induced endomorphism on homology,
we study the eigenvalues and eigenspaces of the latter. Taking a filtration of
representations, we define the persistence of the eigenspaces, effectively introducing
a hierarchical organization of the map. The algorithm that computes this information
for a finite sample is proved to be stable, and to give the correct answer for
a sufficiently dense sample. Results computed with an implementation of the algorithm
provide evidence of its practical utility.\r\n"

text: Opacity is a generic security property, that has been defined on (non-probabilistic)
transition systems and later on Markov chains with labels. For a secret predicate,
given as a subset of runs, and a function describing the view of an external observer,
the value of interest for opacity is a measure of the set of runs disclosing the
secret. We extend this definition to the richer framework of Markov decision processes,
where non-deterministicchoice is combined with probabilistic transitions, and
we study related decidability problems with partial or complete observation hypotheses
for the schedulers. We prove that all questions are decidable with complete observation
and ω-regular secrets. With partial observation, we prove that all quantitative
questions are undecidable but the question whether a system is almost surely non-opaquebecomes
decidable for a restricted class of ω-regular secrets, as well as for all ω-regular
secrets under finite-memory schedulers.

text: 'We study the spectrum of a large system of N identical bosons interacting
via a two-body potential with strength 1/N. In this mean-field regime, Bogoliubov''s
theory predicts that the spectrum of the N-particle Hamiltonian can be approximated
by that of an effective quadratic Hamiltonian acting on Fock space, which describes
the fluctuations around a condensed state. Recently, Bogoliubov''s theory has
been justified rigorously in the case that the low-energy eigenvectors of the
N-particle Hamiltonian display complete condensation in the unique minimizer of
the corresponding Hartree functional. In this paper, we shall justify Bogoliubov''s
theory for the high-energy part of the spectrum of the N-particle Hamiltonian
corresponding to (non-linear) excited states of the Hartree functional. Moreover,
we shall extend the existing results on the excitation spectrum to the case of
non-uniqueness and/or degeneracy of the Hartree minimizer. In particular, the
latter covers the case of rotating Bose gases, when the rotation speed is large
enough to break the symmetry and to produce multiple quantized vortices in the
Hartree minimizer. '

text: 'We consider the spectral statistics of large random band matrices on mesoscopic
energy scales. We show that the correlation function of the local eigenvalue density
exhibits a universal power law behaviour that differs from the Wigner-Dyson- Mehta
statistics. This law had been predicted in the physics literature by Altshuler
and Shklovskii in (Zh Eksp Teor Fiz (Sov Phys JETP) 91(64):220(127), 1986); it
describes the correlations of the eigenvalue density in general metallic sampleswith
weak disorder. Our result rigorously establishes the Altshuler-Shklovskii formulas
for band matrices. In two dimensions, where the leading term vanishes owing to
an algebraic cancellation, we identify the first non-vanishing term and show that
it differs substantially from the prediction of Kravtsov and Lerner in (Phys Rev
Lett 74:2563-2566, 1995). The proof is given in the current paper and its companion
(Ann. H. Poincaré. arXiv:1309.5107, 2014). '
