text: We give a comprehensive introduction into a diagrammatic method that allows
for the evaluation of Gutzwiller wave functions in finite spatial dimensions.
We discuss in detail some numerical schemes that turned out to be useful in the
real-space evaluation of the diagrams. The method is applied to the problem of
d-wave superconductivity in a two-dimensional single-band Hubbard model. Here,
we discuss in particular the role of long-range contributions in our diagrammatic
expansion. We further reconsider our previous analysis on the kinetic energy gain
in the superconducting state.

text: Motion tracking is a challenge the visual system has to solve by reading out
the retinal population. It is still unclear how the information from different
neurons can be combined together to estimate the position of an object. Here we
recorded a large population of ganglion cells in a dense patch of salamander and
guinea pig retinas while displaying a bar moving diffusively. We show that the
bar’s position can be reconstructed from retinal activity with a precision in
the hyperacuity regime using a linear decoder acting on 100+ cells. We then took
advantage of this unprecedented precision to explore the spatial structure of
the retina’s population code. The classical view would have suggested that the
firing rates of the cells form a moving hill of activity tracking the bar’s position.
Instead, we found that most ganglion cells in the salamander fired sparsely and
idiosyncratically, so that their neural image did not track the bar. Furthermore,
ganglion cell activity spanned an area much larger than predicted by their receptive
fields, with cells coding for motion far in their surround. As a result, population
redundancy was high, and we could find multiple, disjoint subsets of neurons that
encoded the trajectory with high precision. This organization allows for diverse
collections of ganglion cells to represent high-accuracy motion information in
a form easily read out by downstream neural circuits.

text: By hybridization and backcrossing, alleles can surmount species boundaries
and be incorporated into the genome of a related species. This introgression of
genes is of particular evolutionary relevance if it involves the transfer of adaptations
between populations. However, any beneficial allele will typically be associated
with other alien alleles that are often deleterious and hamper the introgression
process. In order to describe the introgression of an adaptive allele, we set
up a stochastic model with an explicit genetic makeup of linked and unlinked deleterious
alleles. Based on the theory of reducible multitype branching processes, we derive
a recursive expression for the establishment probability of the beneficial allele
after a single hybridization event. We furthermore study the probability that
slightly deleterious alleles hitchhike to fixation. The key to the analysis is
a split of the process into a stochastic phase in which the advantageous alleles
establishes and a deterministic phase in which it sweeps to fixation. We thereafter
apply the theory to a set of biologically relevant scenarios such as introgression
in the presence of many unlinked or few closely linked deleterious alleles. A
comparison to computer simulations shows that the approximations work well over
a large parameter range.

text: The recently proposed diagrammatic expansion (DE) technique for the full Gutzwiller
wave function (GWF) is applied to the Anderson lattice model. This approach allows
for a systematic evaluation of the expectation values with full Gutzwiller wave
function in finite-dimensional systems. It introduces results extending in an
essential manner those obtained by means of the standard Gutzwiller approximation
(GA), which is variationally exact only in infinite dimensions. Within the DE-GWF
approach we discuss the principal paramagnetic properties and their relevance
to heavy-fermion systems. We demonstrate the formation of an effective, narrow
f band originating from atomic f-electron states and subsequently interpret this
behavior as a direct itineracy of f electrons; it represents a combined effect
of both the hybridization and the correlations induced by the Coulomb repulsive
interaction. Such a feature is absent on the level of GA, which is equivalent
to the zeroth order of our expansion. Formation of the hybridization- and electron-concentration-dependent
narrow f band rationalizes the common assumption of such dispersion of f levels
in the phenomenological modeling of the band structure of CeCoIn5. Moreover, it
is shown that the emerging f-electron direct itineracy leads in a natural manner
to three physically distinct regimes within a single model that are frequently
discussed for 4f- or 5f-electron compounds as separate model situations. We identify
these regimes as (i) the mixed-valence regime, (ii) Kondo/almost-Kondo insulating
regime, and (iii) the Kondo-lattice limit when the f-electron occupancy is very
close to the f-state half filling, ⟨nˆf⟩→1. The nonstandard features of the emerging
correlated quantum liquid state are stressed.

text: 'The activity of a neural network is defined by patterns of spiking and silence
from the individual neurons. Because spikes are (relatively) sparse, patterns
of activity with increasing numbers of spikes are less probable, but, with more
spikes, the number of possible patterns increases. This tradeoff between probability
and numerosity is mathematically equivalent to the relationship between entropy
and energy in statistical physics. We construct this relationship for populations
of up to N = 160 neurons in a small patch of the vertebrate retina, using a combination
of direct and model-based analyses of experiments on the response of this network
to naturalistic movies. We see signs of a thermodynamic limit, where the entropy
per neuron approaches a smooth function of the energy per neuron as N increases.
The form of this function corresponds to the distribution of activity being poised
near an unusual kind of critical point. We suggest further tests of criticality,
and give a brief discussion of its functional significance. '

text: 'In mean-payoff games, the objective of the protagonist is to ensure that
the limit average of an infinite sequence of numeric weights is nonnegative. In
energy games, the objective is to ensure that the running sum of weights is always
nonnegative. Multi-mean-payoff and multi-energy games replace individual weights
by tuples, and the limit average (resp., running sum) of each coordinate must
be (resp., remain) nonnegative. We prove finite-memory determinacy of multi-energy
games and show inter-reducibility of multi-mean-payoff and multi-energy games
for finite-memory strategies. We improve the computational complexity for solving
both classes with finite-memory strategies: we prove coNP-completeness improving
the previous known EXPSPACE bound. For memoryless strategies, we show that deciding
the existence of a winning strategy for the protagonist is NP-complete. We present
the first solution of multi-mean-payoff games with infinite-memory strategies:
we show that mean-payoff-sup objectives can be decided in NP∩coNP, whereas mean-payoff-inf
objectives are coNP-complete.'

text: We use the dual boson approach to reveal the phase diagram of the Fermi-Hubbard
model with long-range dipole-dipole interactions. By using a large-scale finite-temperature
calculation on a 64×64 square lattice we demonstrate the existence of a novel
phase, possessing an "ultralong-range" order. The fingerprint of this
phase - the density correlation function - features a nontrivial behavior on a
scale of tens of lattice sites. We study the properties and the stability of the
ultralong-range-ordered phase, and show that it is accessible in modern experiments
with ultracold polar molecules and magnetic atoms.

text: Given a convex function (Formula presented.) and two hermitian matrices A
and B, Lewin and Sabin study in (Lett Math Phys 104:691–705, 2014) the relative
entropy defined by (Formula presented.). Among other things, they prove that the
so-defined quantity is monotone if and only if (Formula presented.) is operator
monotone. The monotonicity is then used to properly define (Formula presented.)
for bounded self-adjoint operators acting on an infinite-dimensional Hilbert space
by a limiting procedure. More precisely, for an increasing sequence of finite-dimensional
projections (Formula presented.) with (Formula presented.) strongly, the limit
(Formula presented.) is shown to exist and to be independent of the sequence of
projections (Formula presented.). The question whether this sequence converges
to its "obvious" limit, namely (Formula presented.), has been left open.
We answer this question in principle affirmatively and show that (Formula presented.).
If the operators A and B are regular enough, that is (A − B), (Formula presented.)
and (Formula presented.) are trace-class, the identity (Formula presented.) holds.

text: Vegetation clearing and land-use change have depleted many natural plant communities
to the point where restoration is required. A major impediment to the success
of rebuilding complex vegetation communities is having regular access to sufficient
quantities of high-quality seed. Seed-production areas (SPAs) can help generate
this seed, but these must be underpinned by a broad genetic base to maximise the
evolutionary potential of restored populations. However, genetic bottlenecks can
occur at the collection, establishment and production stages in SPAs, requiring
genetic evaluation. This is especially relevant for species that may take many
years before a return on SPA investment is realised. Two recently established
yellow box (Eucalyptus melliodora A.Cunn. ex Schauer, Myrtaceae) SPAs were evaluated
to determine whether genetic bottlenecks had occurred between seed collection
and SPA establishment. No evidence was found to suggest that a significant loss
of genetic diversity had occurred at this stage, although there was a significant
difference in diversity between the two SPAs. Complex population genetic structure
was also observed in the seed used to source the SPAs, with up to eight groups
identified. Plant survival in the SPAs was influenced by seed collection location
but not by SPA location and was not associated with genetic diversity. There were
also no associations between genetic diversity and plant growth. These data highlighted
the importance of chance events when establishing SPAs and indicated that the
two yellow box SPAs are likely to provide genetically diverse seed sources for
future restoration projects, especially by pooling seed from both SPAs.

text: We consider a problem of learning kernels for use in SVM classification in
the multi-task and lifelong scenarios and provide generalization bounds on the
error of a large margin classifier. Our results show that, under mild conditions
on the family of kernels used for learning, solving several related tasks simultaneously
is beneficial over single task learning. In particular, as the number of observed
tasks grows, assuming that in the considered family of kernels there exists one
that yields low approximation error on all tasks, the overhead associated with
learning such a kernel vanishes and the complexity converges to that of learning
when this good kernel is given to the learner.
