The onset, evolution and magnetic braking of vortex lattice instabilities in nanostructured superconducting films

O. -A. Adami, Ž. L. Jelić, C. Xue +6

In 1976 Larkin and Ovchinnikov [Sov. Phys. JETP 41, 960 (1976)] predicted that vortex matter in superconductors driven by an electrical current can undergo an abrupt dynamic transi…

Testing for Differences in Gaussian Graphical Models: Applications to Brain Connectivity

Eugene Belilovsky, Gaël Varoquaux, Matthew B. Blaschko

Functional brain networks are well described and estimated from data with Gaussian Graphical Models (GGMs), e.g. using sparse inverse covariance estimators. Comparing functional co…

An exponentially local spectral flow for possibly non-self-adjoint perturbations of non-interacting quantum spins, inspired by KAM theory

Wojciech De Roeck, Marius Schütz

Since its introduction by Hastings in [10], the technique of quasi-adiabatic continuation has become a central tool in the discussion and classification of ground state phases. It…

Inter-ribbon tunneling in graphene: an atomistic Bardeen approach

Maarten L. Van de Put, William G. Vandenberghe, Bart Sorée +2

A weakly coupled system of two crossed graphene nanoribbons exhibits direct tunneling due to the overlap of the wavefunctions of both ribbons. We apply the Bardeen transfer Hamilto…

Strong solidity of free Araki-Woods factors

Rémi Boutonnet, Cyril Houdayer, Stefaan Vaes

We show that Shlyakhtenko's free Araki-Woods factors are strongly solid, meaning that for any diffuse amenable von Neumann subalgebra that is the range of a normal conditional expe…

Nilpotent chiral superfield in N=2 supergravity and partial rigid supersymmetry breaking

Sergei M. Kuzenko, Gabriele Tartaglino-Mazzucchelli

In the framework of N=2 conformal supergravity in four dimensions, we introduce a nilpotent chiral superfield suitable for the description of partial supersymmetry breaking in maxi…

Rank Pooling for Action Recognition

Basura Fernando, Efstratios Gavves, Jose Oramas +2

We propose a function-based temporal pooling method that captures the latent structure of the video sequence data - e.g. how frame-level features evolve over time in a video. We sh…

Toward an Efficient Website Fingerprinting Defense

Marc Juarez, Mohsen Imani, Mike Perry +2

Website Fingerprinting attacks enable a passive eavesdropper to recover the user's otherwise anonymized web browsing activity by matching the observed traffic with prerecorded web…

Remarks on scale separation in flux vacua

F. F. Gautason, M. Schillo, T. Van Riet +1

We argue that the Maldacena-Nunez no-go theorem excluding Minkowski and de Sitter vacua in flux compactifications can be extended to exclude anti-de Sitter (AdS) vacua for which th…

Highly Scalable Tensor Factorization for Prediction of Drug-Protein Interaction Type

Adam Arany, Jaak Simm, Pooya Zakeri +5

The understanding of the type of inhibitory interaction plays an important role in drug design. Therefore, researchers are interested to know whether a drug has competitive or non-…
