Rost nilpotence and free theories (2018)
Journal Article

We introduce coherent cohomology theories h_* and prove that if such a theory is moreover generically constant then the Rost nilpotence principle holds for projective homogeneous varieties in the category of h_*-motives. Examples of such theories are... Read More about Rost nilpotence and free theories.

Mutation and Selection in Bacteria: Modelling and Calibration (2018)
Journal Article

© 2018, The Author(s). Temporal evolution of a clonal bacterial population is modelled taking into account reversible mutation and selection mechanisms. For the mutation model, an efficient algorithm is proposed to verify whether experimental data ca... Read More about Mutation and Selection in Bacteria: Modelling and Calibration.

Analysis of networks where discontinuities and nonsmooth dynamics collide: understanding synchrony (2018)
Journal Article

Integrate-and-fire networks have proven remarkably useful in modelling the dynamics of real world phenomena ranging from earthquakes, to synchrony in neural networks, to cascading activity in social networks. The reset process means that such models... Read More about Analysis of networks where discontinuities and nonsmooth dynamics collide: understanding synchrony.

Stochastic electromagnetic field propagation: measurement and modelling (2018)
Journal Article

This paper reviews recent progress in the measurement and modelling of stochastic electromagnetic fields, focusing on propagation approaches based on Wigner functions and the method of moments technique. The respective propagation methods are exempli... Read More about Stochastic electromagnetic field propagation: measurement and modelling.

Compensated convexity methods for approximations and interpolations of sampled functions in Euclidean spaces: applications to contour lines, sparse data and inpainting (2018)
Journal Article

This paper is concerned with applications of the theory of approximation and interpolation based on compensated convex transforms developed in [55]. We apply our methods to (i) surface reconstruction starting from the knowledge of finitely many level...

Extreme values of CUE characteristic polynomials: a numerical study (2018)
Journal Article

We present the results of systematic numerical computations relating to the extreme value statistics of the characteristic polynomials of random unitary matrices drawn from the circular unitary ensemble (CUE) of random matrix theory. In particular, w... Read More about Extreme values of CUE characteristic polynomials: a numerical study.

Spatial attention affects the early processing of neutral versus fearful faces when they are task-irrelevant: a classifier study of the EEG C1 component (2018)
Journal Article

EEG studies suggest that the emotional content of visual stimuli is processed rapidly. In particular, the C1 component, which occurs up to 100 ms after stimulus onset and likely reflects activity in primary visual cortex V1, has been reported to be s...

Generic emergence of objectivity of observables in infinite dimensions (2018)
Journal Article

Quantum Darwinism posits that information becomes objective whenever multiple observers indirectly probe a quantum system by each measuring a fraction of the environment. It was recently shown that objectivity of observables emerges generically from... Read More about Generic emergence of objectivity of observables in infinite dimensions.

Certification and quantification of multilevel quantum coherence (2018)
Journal Article

Quantum coherence, present whenever a quantum system exists in a superposition of multiple classically distinct states, marks one of the fundamental departures from classical physics. Quantum coherence has recently been investigated rigorously within... Read More about Certification and quantification of multilevel quantum coherence.

The effect of forest dislocations on the evolution of a phase-field model for plastic slip (2018)
Journal Article

We consider the gradient flow evolution of a phase-field model for crystal dislocations in a single slip system in the presence of forest dislocations. The model is based on a Peierls-Nabarro type energy penalizing non-integer slip and elastic stress...

Elastodynamics on graphs: wave propagation on networks of plates (2018)
Journal Article

We consider the wave dynamics on networks of plates coupled along 1D joints. This set-up can be mapped onto an extension of wave graph systems studied in, for example, quantum graph theory. In the elastic case, different mode-types (flexural, longitu... Read More about Elastodynamics on graphs: wave propagation on networks of plates.

Thermality from a Rindler quench (2018)
Journal Article

© 2018 IOP Publishing Ltd. Ultracold fermionic atoms in an optical lattice, with a sudden position-dependent change (a quench) in the effective dispersion relation, have been proposed by Rodríguez-Laguna et al as an analogue spacetime test of the Unr...

The structure of a dewetting rim with strong slip: the long-time evolution (2018)
Journal Article

When a thin viscous film dewets from a solid substrate, the liquid forms a characteristic rim near the contact line as the contact line retracts. The shape of the rim and also the retraction rate vary strongly with the amount of slip that occurs at t...

The geometry of Sloppiness (2018)
Journal Article

The use of mathematical models in the sciences often involves the estimation of unknown parameter values from data. Sloppiness provides information about the uncertainty of this task. In this paper, we develop a precise mathematical foundation for sl... Read More about The geometry of Sloppiness.

Fermions, differential forms and doubled geometry (2018)
Journal Article

© 2018 The Author We show that all fermions of one generation of the Pati–Salam version of the Standard Model (SM) can be elegantly described by a single fixed parity (say even) inhomogeneous real-valued differential form in seven dimensions. In this... Read More about Fermions, differential forms and doubled geometry.

Gravity with more or less gauging (2018)
Journal Article

General relativity is usually formulated as a theory with gauge invariance under the diffeomorphism group, but there is a 'dilaton' formulation where it is in addition invariant under Weyl transformations, and a 'unimodular' formulation where it is o...

Network mechanisms underlying the role of oscillations in cognitive tasks (2018)
Journal Article

Oscillatory activity robustly correlates with task demands during many cognitive tasks. However, not only are the network mechanisms underlying the generation of these rhythms poorly understood, but it is also still unknown to what extent they may pl...

Causal structure of black holes in shift-symmetric Horndeski theories (2018)
Journal Article

In theories with derivative (self-)interactions, the propagation of perturbations on nontrivial field configurations is determined by effective metrics. Generalized scalar-tensor theories belong in this class and this implies that the matter fields a... Read More about Causal structure of black holes in shift-symmetric Horndeski theories.

Metallome of cerebrovascular endothelial cells infected with Toxoplasma gondii using ?-XRF imaging and inductively coupled plasma mass spectrometry (2018)
Journal Article

In this study, we measured the levels of elements in human brain microvascular endothelial cells (ECs) infected with T. gondii. ECs were infected with tachyzoites of the RH strain, and at 6, 24, and 48 hours post infection (hpi), the intracellular co...
