Magnetic order and spin dynamics across a ferromagnetic quantum critical point: $μ$SR investigations of YbNi$_4$(P$_{1-x}$As$_x$)$_2$ | In the quasi-1D heavy-fermion system YbNi$_4$(P$_{1-x}$As$_x$)$_2$ the
presence of a ferromagnetic (FM) quantum critical point (QCP) at $x_c$ $\approx
0.1$ with unconventional quantum critical exponents in the thermodynamic
properties has been recently reported. Here, we present muon-spin relaxation

Pixel-Level Statistical Analyses of Prescribed Fire Spread | Wildland fire dynamics is a complex turbulent dimensional process. Cellular
automata (CA) is an efficient tool to predict fire dynamics, but the main
parameters of the method are challenging to estimate. To overcome this
challenge, we compute statistical distributions of the key parameters of a CA
model using infrare... | 0 | 1 | 0 | 0 | 0 | 0 |
Deep Reinforcement Learning for Swarm Systems | Recently, deep reinforcement learning (RL) methods have been applied
successfully to multi-agent scenarios. Typically, these methods rely on a
concatenation of agent states to represent the information content required for
decentralized decision making. However, concatenation scales poorly to swarm
systems with a lar... | 1 | 0 | 0 | 1 | 0 | 0 |
Predicting computational reproducibility of data analysis pipelines in large population studies using collaborative filtering | Evaluating the computational reproducibility of data analysis pipelines has
become a critical issue. It is, however, a cumbersome process for analyses that

reproducibi... | 0 | 0 | 0 | 1 | 0 | 0 |
Experiment Segmentation in Scientific Discourse as Clause-level Structured Prediction using Recurrent Neural Networks | We propose a deep learning model for identifying structure within experiment
narratives in scientific literature. We take a sequence labeling approach to
this problem, and label clauses within experiment narratives to identify the

Information-Theoretic Analysis of Refractory Effects in the P300 Speller | The P300 speller is a brain-computer interface that enables people with
neuromuscular disorders to communicate based on eliciting event-related
potentials (ERP) in electroencephalography (EEG) measurements. One challenge to
reliable communication is the presence of refractory effects in the P300 ERP
that induces temp... | 1 | 0 | 1 | 0 | 0 | 0 |
Growth, Industrial Externality, Prospect Dynamics and Well-being on Markets | Functions or 'functionnings' enable to give a structure to any economic
activity whether they are used to describe a good or a service that is
exchanged on a market or they constitute the capability of an agent to provide
the labor market with specific work and skills. That structure encompasses the
basic law of supp... | 0 | 0 | 0 | 0 | 0 | 1 |
Structure Preserving Model Reduction of Parametric Hamiltonian Systems | While reduced-order models (ROMs) have been popular for efficiently solving

symplectic struc... | 0 | 0 | 1 | 0 | 0 | 0 |
Consensus measure of rankings | A ranking is an ordered sequence of items, in which an item with higher
ranking score is more preferred than the items with lower ranking scores. In
many information systems, rankings are widely used to represent the preferences
over a set of items or candidates. The consensus measure of rankings is the
problem of ho... | 1 | 0 | 0 | 0 | 0 | 0 |
Possible resonance effect of dark matter axions in SNS Josephson junctions | Dark matter axions can generate peculiar effects in special types of
Josephson junctions, so-called SNS junctions. One can show that the axion field
equations in a Josephson environment allow for very small oscillating
supercurrents, which manifest themselves as a tiny wiggle in the I-V curve, a
so-called Shapiro ste... | 0 | 1 | 0 | 0 | 0 | 0 |
A Composition Theorem for Randomized Query Complexity | Let the randomized query complexity of a relation for error probability

Soliton solutions for the elastic metric on spaces of curves | In this article we investigate a first order reparametrization-invariant
Sobolev metric on the space of immersed curves. Motivated by applications in
shape analysis where discretizations of this infinite-dimensional space are

wellposedness ... | 0 | 0 | 1 | 0 | 0 | 0 |
Influence of Personal Preferences on Link Dynamics in Social Networks | We study a unique network dataset including periodic surveys and electronic

PBW bases and marginally large tableaux in types B and C | We explicitly describe the isomorphism between two combinatorial realizations
of Kashiwara's infinity crystal in types B and C. The first realization is in

Ensemble Clustering for Graphs | We propose an ensemble clustering algorithm for graphs (ECG), which is based

Testing for Feature Relevance: The HARVEST Algorithm | Feature selection with high-dimensional data and a very small proportion of
