Shot noise in ultrathin superconducting wires | Quantum phase slips (QPS) may produce non-equilibrium voltage fluctuations in

Linearity of stability conditions | We study different concepts of stability for modules over a finite

nonlinear stability given by the wall-crossing sequence of a "green path". Two
other concepts, finite Harder-Narasimhan stratification of the module category
and maximal forward h... | 0 | 0 | 1 | 0 | 0 | 0 |
Urban Data Streams and Machine Learning: A Case of Swiss Real Estate Market | In this paper, we show how using publicly available data streams and machine

BinPro: A Tool for Binary Source Code Provenance | Enforcing open source licenses such as the GNU General Public License (GPL),

The placement of the head that maximizes predictability. An information theoretic approach | The minimization of the length of syntactic dependencies is a
well-established principle of word order and the basis of a mathematical theory

predictability of a target ... | 1 | 1 | 0 | 0 | 0 | 0 |
Nonparametric regression using deep neural networks with ReLU activation function | Consider the multivariate nonparametric regression model. It is shown that

Unsupervised Learning of Neural Networks to Explain Neural Networks (extended abstract) | This paper presents an unsupervised method to learn a neural network, namely

Measuring Cognitive Conflict in Virtual Reality with Feedback-Related Negativity | As virtual reality (VR) emerges as a mainstream platform, designers have

Strong deformations of DNA: Effect on the persistence length | Extreme deformations of the DNA double helix attracted a lot of attention

Raman scattering study of tetragonal magnetic phase in Sr$_{1-x}$Na$_x$Fe$_2$As$_2$: structural symmetry and electronic gap | We use inelastic light scattering to study Sr$_{1-x}$Na$_x$Fe$_2$As$_2$

Learning Mixture of Gaussians with Streaming Data | In this paper, we study the problem of learning a mixture of Gaussians with

parameters using a single pass over the data stream. We analyze a streaming

Electrostatic gyrokinetic simulation of global tokamak boundary plasma and the generation of nonlinear intermittent turbulence | Boundary plasma physics plays an important role in tokamak confinement, but

Enhancing Interpretability of Black-box Soft-margin SVM by Integrating Data-based Priors | The lack of interpretability often makes black-box models difficult to be
