A Lifelong Learning Approach to Brain MR Segmentation Across Scanners and Protocols | Convolutional neural networks (CNNs) have shown promising results on several

CNNs may degrade severely when segmenting images acquired with different
scanners and/or protocols as compared to the training data, thus limiting their

Hybrid Kinematic Control for Rigid Body Pose Stabilization using Dual Quaternions | In this paper, we address the rigid body pose stabilization problem using
dual quaternion formalism. We propose a hybrid control strategy to design a
switching control law with hysteresis in such a way that the global asymptotic
stability of the closed-loop system is guaranteed and such that the global
attractivity o... | 1 | 0 | 1 | 0 | 0 | 0 |
On 2d-4d motivic wall-crossing formulas | In this paper we propose definitions and examples of categorical enhancements

On Quitting: Performance and Practice in Online Game Play | We study the relationship between performance and practice by analyzing the

Video Labeling for Automatic Video Surveillance in Security Domains | Beyond traditional security methods, unmanned aerial vehicles (UAVs) have

On density of subgraphs of Cartesian products | In this paper, we extend two classical results about the density of subgraphs
of hypercubes to subgraphs $G$ of Cartesian products $G_1\times\cdots\times
G_m$ of arbitrary connected graphs. Namely, we show that

Replica Analysis for Maximization of Net Present Value | In this paper, we use replica analysis to determine the investment strategy

On some properties of weak solutions to elliptic equations with divergence-free drifts | We discuss the local properties of weak solutions to the equation $-\Delta u

the case $b\in L_2$. In this case the structure assumption $\operatorname{div}

The heptagon-wheel cocycle in the Kontsevich graph complex | The real vector space of non-oriented graphs is known to carry a differential

Maneuver Regulation for Accelerating Bodies in Atmospheric Environments | In order to address the need for an affordable reduced gravity test platform,

A Hybrid Deep Learning Approach for Texture Analysis | Texture classification is a problem that has various applications such as

Accounting Noise and the Pricing of CoCos | Contingent Convertible bonds (CoCos) are debt instruments that convert into

On quartic double fivefolds and the matrix factorizations of exceptional quaternionic representations | We study quartic double fivefolds from the perspective of Fano manifolds of

Atmospheric thermal tides and planetary spin I. The complex interplay between stratification and rotation | Thermal atmospheric tides can torque telluric planets away from spin-orbit
synchronous rotation, as observed in the case of Venus. They thus participate

Inferring Generative Model Structure with Static Analysis | Obtaining enough labeled data to robustly train complex discriminative models
