text: We consider non-interacting particles subject to a fixed external potential
V and a self-generated magnetic field B. The total energy includes the field energy
β∫B2 and we minimize over all particle states and magnetic fields. In the case
of spin-1/2 particles this minimization leads to the coupled Maxwell-Pauli system.
The parameter β tunes the coupling strength between the field and the particles
and it effectively determines the strength of the field. We investigate the stability
and the semiclassical asymptotics, h→0, of the total ground state energy E(β,h,V).
The relevant parameter measuring the field strength in the semiclassical limit
is κ=βh. We are not able to give the exact leading order semiclassical asymptotics
uniformly in κ or even for fixed κ. We do however give upper and lower bounds
on E with almost matching dependence on κ. In the simultaneous limit h→0 and κ→∞
we show that the standard non-magnetic Weyl asymptotics holds. The same result
also holds for the spinless case, i.e. where the Pauli operator is replaced by
the Schrödinger operator.

text: Even though both population and quantitative genetics, and evolutionary computation,
deal with the same questions, they have developed largely independently of each
other. I review key results from each field, emphasising those that apply independently
of the (usually unknown) relation between genotype and phenotype. The infinitesimal
model provides a simple framework for predicting the response of complex traits
to selection, which in biology has proved remarkably successful. This allows one
to choose the schedule of population sizes and selection intensities that will
maximise the response to selection, given that the total number of individuals
realised, C = ∑t Nt, is constrained. This argument shows that for an additive
trait (i.e., determined by the sum of effects of the genes), the optimum population
size and the maximum possible response (i.e., the total change in trait mean)
are both proportional to √C.

text: Prediction of the evolutionary process is a long standing problem both in
the theory of evolutionary biology and evolutionary computation (EC). It has long
been realized that heritable variation is crucial to both the response to selection
and the success of genetic algorithms. However, not all variation contributes
in the same way to the response. Quantitative genetics has developed a large body
of work trying to estimate and understand how different components of the variance
in fitness in the population contribute to the response to selection. We illustrate
how to apply some concepts of quantitative genetics to the analysis of genetic
algorithms. In particular, we derive estimates for the short term prediction of
the response to selection and we use variance decomposition to gain insight on
local aspects of the landscape. Finally, we propose a new population based genetic
algorithm that uses these methods to improve its operation.

text: 'Knowledge of the rate and fitness effects of mutations is essential for understanding
the process of evolution. Mutations are inherently difficult to study because
they are rare and are frequently eliminated by natural selection. In the ciliate
Tetrahymena thermophila, mutations can accumulate in the germline genome without
being exposed to selection. We have conducted a mutation accumulation (MA) experiment
in this species. Assuming that all mutations are deleterious and have the same
effect, we estimate that the deleterious mutation rate per haploid germline genome
per generation is U = 0.0047 (95% credible interval: 0.0015, 0.0125), and that
germline mutations decrease fitness by s = 11% when expressed in a homozygous
state (95% CI: 4.4%, 27%). We also estimate that deleterious mutations are partially
recessive on average (h = 0.26; 95% CI: –0.022, 0.62) and that the rate of lethal
mutations is <10% of the deleterious mutation rate. Comparisons between the
observed evolutionary responses in the germline and somatic genomes and the results
from individual-based simulations of MA suggest that the two genomes have similar
mutational parameters. These are the first estimates of the deleterious mutation
rate and fitness effects from the eukaryotic supergroup Chromalveolata and are
within the range of those of other eukaryotes.'

text: We consider a general class of random matrices whose entries are centred random
variables, independent up to a symmetry constraint. We establish precise high-probability
bounds on the averages of arbitrary monomials in the resolvent matrix entries.
Our results generalize the previous results of Erdős et al. (Ann Probab, arXiv:1103.1919,
2013; Commun Math Phys, arXiv:1103.3869, 2013; J Combin 1(2):15-85, 2011) which
constituted a key step in the proof of the local semicircle law with optimal error
bound in mean-field random matrix models. Our bounds apply to random band matrices
and improve previous estimates from order 2 to order 4 in the cases relevant to
applications. In particular, they lead to a proof of the diffusion approximation
for the magnitude of the resolvent of random band matrices. This, in turn, implies
new delocalization bounds on the eigenvectors. The applications are presented
in a separate paper (Erdős et al., arXiv:1205.5669, 2013).

text: 'We consider the ensemble of adjacency matrices of Erdős-Rényi random graphs,
that is, graphs on N vertices where every edge is chosen independently and with
probability p = p(N). We rescale the matrix so that its bulk eigenvalues are of
order one. We prove that, as long as pN→∞(with a speed at least logarithmic in
N), the density of eigenvalues of the Erdős-Rényi ensemble is given by the Wigner
semicircle law for spectral windows of length larger than N-1 (up to logarithmic
corrections). As a consequence, all eigenvectors are proved to be completely delocalized
in the sense that the ℓ∞-norms of the ℓ2-normalized eigenvectors are at most of
order N-1/2 with a very high probability. The estimates in this paper will be
used in the companion paper [Spectral statistics of Erdős-Rényi graphs II: Eigenvalue
spacing and the extreme eigenvalues (2011) Preprint] to prove the universality
of eigenvalue distributions both in the bulk and at the spectral edges under the
further restriction that pN »N2/3.'

text: We consider random n×n matrices of the form (XX*+YY*)^{-1/2}YY*(XX*+YY*)^{-1/2},
where X and Y have independent entries with zero mean and variance one. These
matrices are the natural generalization of the Gaussian case, which are known
as MANOVA matrices and which have joint eigenvalue density given by the third
classical ensemble, the Jacobi ensemble. We show that, away from the spectral
edge, the eigenvalue density converges to the limiting density of the Jacobi ensemble
even on the shortest possible scales of order 1/n (up to log n factors). This
result is the analogue of the local Wigner semicircle law and the local Marchenko-Pastur
law for general MANOVA matrices.

text: Transition in shear flows is characterized by localized turbulent regions
embedded in the surrounding laminar flow. These so-called turbulent spots or puffs
are observed in a variety of shear flows and in certain Reynolds-number regimes,
and they are advected by the flow while keeping their characteristic length. We
show here for the case of pipe flow that this seemingly passive advection of turbulent
puffs involves continuous entrainment and relaminarization of laminar and turbulent
fluid across strongly convoluted interfaces. Surprisingly, interface areas are
almost two orders of magnitude larger than the pipe cross-section, while local
entrainment velocities are much smaller than the mean speed. Even though these
velocities were shown to be small and proportional to the Kolmogorov velocity
scale (in agreement with a prediction by Corrsin) in a flow without mean shear
before, we find that, in pipe flow, local entrainment velocities are about an
order of magnitude smaller than this scale. The Lagrangian method used to study
the dynamics of the laminar-turbulent interfaces allows accurate determination
of the leading and trailing edge speeds. However, to resolve the highly complex
interface dynamics requires much higher numerical resolutions than for ordinary
turbulent flows. This method also reveals that the volume flux across the leading
edge has the same radial dependence but the opposite sign as that across the trailing
edge, and it is this symmetry that is responsible for the puff shape remaining
constant.

text: A novel Taylor-Couette system has been constructed for investigations of transitional
as well as high Reynolds number turbulent flows in very large aspect ratios. The
flexibility of the setup enables studies of a variety of problems regarding hydrodynamic
instabilities and turbulence in rotating flows. The inner and outer cylinders
and the top and bottom endplates can be rotated independently with rotation rates
of up to 30 Hz, thereby covering five orders of magnitude in Reynolds numbers
(Re = 101-106). The radius ratio can be easily changed, the highest realized one
is η = 0.98 corresponding to an aspect ratio of 260 gap width in the vertical
and 300 in the azimuthal direction. For η < 0.98 the aspect ratio can be dynamically
changed during measurements and complete transparency in the radial direction
over the full length of the cylinders is provided by the usage of a precision
glass inner cylinder. The temperatures of both cylinders are controlled independently.
Overall this apparatus combines an unmatched variety in geometry, rotation rates,
and temperatures, which is provided by a sophisticated high-precision bearing
system. Possible applications are accurate studies of the onset of turbulence
and spatio-temporal intermittent flow patterns in very large domains, transport
processes of turbulence at high Re, the stability of Keplerian flows for different
boundary conditions, and studies of baroclinic instabilities.

text: 'We consider several basic problems of algebraic topology, with connections
to combinatorial and geometric questions, from the point of view of computational
complexity. The extension problem asks, given topological spaces X; Y , a subspace
A ⊆ X, and a (continuous) map f : A → Y , whether f can be extended to a map X
→ Y . For computational purposes, we assume that X and Y are represented as finite
simplicial complexes, A is a subcomplex of X, and f is given as a simplicial map.
In this generality the problem is undecidable, as follows from Novikov''s result
from the 1950s on uncomputability of the fundamental group π1(Y ). We thus study
the problem under the assumption that, for some k ≥ 2, Y is (k - 1)-connected;
informally, this means that Y has \no holes up to dimension k-1" (a basic
example of such a Y is the sphere Sk). We prove that, on the one hand, this problem
is still undecidable for dimX = 2k. On the other hand, for every fixed k ≥ 2,
we obtain an algorithm that solves the extension problem in polynomial time assuming
Y (k - 1)-connected and dimX ≤ 2k - 1. For dimX ≤ 2k - 2, the algorithm also provides
a classification of all extensions up to homotopy (continuous deformation). This
relies on results of our SODA 2012 paper, and the main new ingredient is a machinery
of objects with polynomial-time homology, which is a polynomial-time analog of
objects with effective homology developed earlier by Sergeraert et al. We also
consider the computation of the higher homotopy groups πk(Y ), k ≥ 2, for a 1-connected
Y . Their computability was established by Brown in 1957; we show that πk(Y )
can be computed in polynomial time for every fixed k ≥ 2. On the other hand, Anick
proved in 1989 that computing πk(Y ) is #P-hard if k is a part of input, where
Y is a cell complex with certain rather compact encoding. We strengthen his result
to #P-hardness for Y given as a simplicial complex. '

text: In order to establish a reference for analysis of the function of auxin and
the auxin biosynthesis regulators SHORT INTERNODE/ STYLISH (SHI/STY) during Physcomitrella
patens reproductive development, we have described male (antheridial) and female
(archegonial) development in detail, including temporal and positional information
of organ initiation. This has allowed us to define discrete stages of organ morphogenesis
and to show that reproductive organ development in P. patens is highly organized
and that organ phyllotaxis differs between vegetative and reproductive development.
Using the PpSHI1 and PpSHI2 reporter and knockout lines, the auxin reporters GmGH3pro:GUS
and PpPINApro:GFP-GUS, and the auxin-conjugating transgene PpSHI2pro:IAAL, we
could show that the PpSHI genes, and by inference also auxin, play important roles
for reproductive organ development in moss. The PpSHI genes are required for the
apical opening of the reproductive organs, the final differentiation of the egg
cell, and the progression of canal cells into a cell death program. The apical
cells of the archegonium, the canal cells, and the egg cell are also sites of
auxin responsiveness and are affected by reduced levels of active auxin, suggesting
that auxin mediates PpSHI function in the reproductive organs.

text: The epistatic interactions that underlie evolutionary constraint have mainly
been studied for constant external conditions. However, environmental changes
may modulate epistasis and hence affect genetic constraints. Here we investigate
genetic constraints in the adaptive evolution of a novel regulatory function in
variable environments, using the lac repressor, LacI, as a model system. We have
systematically reconstructed mutational trajectories from wild type LacI to three
different variants that each exhibit an inverse response to the inducing ligand
IPTG, and analyzed the higher-order interactions between genetic and environmental
changes. We find epistasis to depend strongly on the environment. As a result,
mutational steps essential to inversion but inaccessible by positive selection
in one environment, become accessible in another. We present a graphical method
to analyze the observed complex higher-order interactions between multiple mutations
and environmental change, and show how the interactions can be explained by a
combination of mutational effects on allostery and thermodynamic stability. This
dependency of genetic constraint on the environment should fundamentally affect
evolutionary dynamics and affects the interpretation of phylogenetic data.

text: 'In pipe, channel, and boundary layer flows turbulence first occurs intermittently
in space and time: at moderate Reynolds numbers domains of disordered turbulent
motion are separated by quiescent laminar regions. Based on direct numerical simulations
of pipe flow we argue here that the spatial intermittency has its origin in a
nearest neighbor interaction between turbulent regions. We further show that in
this regime turbulent flows are intrinsically intermittent with a well-defined
equilibrium turbulent fraction but without ever assuming a steady pattern. This
transition scenario is analogous to that found in simple models such as coupled
map lattices. The scaling observed implies that laminar intermissions of the turbulent
flow will persist to arbitrarily large Reynolds numbers.'

text: 'We consider the problem of deciding whether the persistent homology group
of a simplicial pair (K, L) can be realized as the homology H* (X) of some complex
X with L ⊂ X ⊂ K. We show that this problem is NP-complete even if K is embedded
in ℝ3. As a consequence, we show that it is NP-hard to simplify level and sublevel
sets of scalar functions on S3 within a given tolerance constraint. This problem
has relevance to the visualization of medical images by isosurfaces. We also show
an implication to the theory of well groups of scalar functions: not every well
group can be realized by some level set, and deciding whether a well group can
be realized is NP-hard.'

text: Turbulence is ubiquitous in nature, yet even for the case of ordinary Newtonian
fluids like water, our understanding of this phenomenon is limited. Many liquids
of practical importance are more complicated (e.g., blood, polymer melts, paints),
however; they exhibit elastic as well as viscous characteristics, and the relation
between stress and strain is nonlinear. We demonstrate here for a model system
of such complex fluids that at high shear rates, turbulence is not simply modified
as previously believed but is suppressed and replaced by a different type of disordered
motion, elasto-inertial turbulence. Elasto-inertial turbulence is found to occur
at much lower Reynolds numbers than Newtonian turbulence, and the dynamical properties
differ significantly. The friction scaling observed coincides with the so-called
"maximum drag reduction" asymptote, which is exhibited by a wide range
of viscoelastic fluids.

text: We study the problem of generating a test sequence that achieves maximal coverage
for a reactive system under test. We formulate the problem as a repeated game
between the tester and the system, where the system state space is partitioned
according to some coverage criterion and the objective of the tester is to maximize
the set of partitions (or coverage goals) visited during the game. We show the
complexity of the maximal coverage problem for non-deterministic systems is PSPACE-complete,
but is NP-complete for deterministic systems. For the special case of non-deterministic
systems with a re-initializing "reset" action, which represent running
a new test input on a re-initialized system, we show that the complexity is coNP-complete.
Our proof technique for reset games uses randomized testing strategies that circumvent
the exponentially large memory requirement of deterministic testing strategies.
We also discuss the memory requirement for deterministic strategies and extensions
of our results to other models, such as pushdown systems and timed systems.

text: The fact that a sum of isotropic Gaussian kernels can have more modes than
kernels is surprising. Extra (ghost) modes do not exist in ℝ1 and are generally
not well studied in higher dimensions. We study a configuration of n+1 Gaussian
kernels for which there are exactly n+2 modes. We show that all modes lie on a
finite set of lines, which we call axes, and study the restriction of the Gaussian
mixture to these axes in order to discover that there are an exponential number
of critical points in this configuration. Although the existence of ghost modes
remained unknown due to the difficulty of finding examples in ℝ2, we show that
the resilience of ghost modes grows like the square root of the dimension. In
addition, we exhibit finite configurations of isotropic Gaussian kernels with
superlinearly many modes.

text: In solid tumors, targeted treatments can lead to dramatic regressions, but
responses are often short-lived because resistant cancer cells arise. The major
strategy proposed for overcoming resistance is combination therapy. We present
a mathematical model describing the evolutionary dynamics of lesions in response
to treatment. We first studied 20 melanoma patients receiving vemurafenib. We
then applied our model to an independent set of pancreatic, colorectal, and melanoma
cancer patients with metastatic disease. We find that dual therapy results in
long-term disease control for most patients, if there are no single mutations
that cause cross-resistance to both drugs; in patients with large disease burden,
triple therapy is needed. We also find that simultaneous therapy with two drugs
is much more effective than sequential therapy. Our results provide realistic
expectations for the efficacy of new drug combinations and inform the design of
trials for new cancer therapeutics.

text: The basic idea of evolutionary game theory is that payoff determines reproductive
rate. Successful individuals have a higher payoff and produce more offspring.
But in evolutionary and ecological situations there is not only reproductive rate
but also carrying capacity. Individuals may differ in their exposure to density
limiting effects. Here we explore an alternative approach to evolutionary game
theory by assuming that the payoff from the game determines the carrying capacity
of individual phenotypes. Successful strategies are less affected by density limitation
(crowding) and reach higher equilibrium abundance. We demonstrate similarities
and differences between our framework and the standard replicator equation. Our
equation is defined on the positive orthant, instead of the simplex, but has the
same equilibrium points as the replicator equation. Linear stability analysis
produces the classical conditions for asymptotic stability of pure strategies,
but the stability properties of internal equilibria can differ in the two frameworks.
For example, in a two-strategy game with an internal equilibrium that is always
stable under the replicator equation, the corresponding equilibrium can be unstable
in the new framework resulting in a limit cycle.

text: Models of neural responses to stimuli with complex spatiotemporal correlation
structure often assume that neurons are selective for only a small number of linear
projections of a potentially high-dimensional input. In this review, we explore
recent modeling approaches where the neural response depends on the quadratic
form of the input rather than on its linear projection, that is, the neuron is
sensitive to the local covariance structure of the signal preceding the spike.
To infer this quadratic dependence in the presence of arbitrary (e.g., naturalistic)
stimulus distribution, we review several inference methods, focusing in particular
on two information theory–based approaches (maximization of stimulus energy and
of noise entropy) and two likelihood-based approaches (Bayesian spike-triggered
covariance and extensions of generalized linear models). We analyze the formal
relationship between the likelihood-based and information-based approaches to
demonstrate how they lead to consistent inference. We demonstrate the practical
feasibility of these procedures by using model neurons responding to a flickering
variance stimulus.
