Computing higher symplectic capacities I. (arXiv:1911.06466v1 [math.SG])

We present recursive formulas which compute the recently defined “higher symplectic capacities” for all convex toric domains. In the special case of four-dimensional ellipsoids, we apply homological perturbation theory to the associated filtered L-infinity algebras and prove that the resulting structure coefficients count punctured pseudoholomorphic curves in cobordisms between ellipsoids. As sample applications, we produce…

Longitudinal analysis of fetal MRI in patients with prenatal spina bifida repair. (arXiv:1911.06542v1 [eess.IV])

Open spina bifida (SB) is one of the most common congenital defects and can lead to impaired brain development. Emerging fetal surgery methods have shown considerable success in the treatment of patients with this severe anomaly. Afterwards, alterations in the brain development of these fetuses have been observed. Currently no longitudinal studies exist to show…

A meshfree formulation for large deformation analysis of flexoelectric structures accounting for the surface effects. (arXiv:1911.06553v1 [physics.comp-ph])

In this work, we present a compactly supported radial basis function (CSRBF) based meshfree method to analyse geometrically nonlinear flexoelectric nanostructures considering surface effects. Flexoelectricity is the polarization of dielectric materials due to the gradient of strain, which is different from piezoelectricity in which polarization is dependent linearly on strain. The surface effects gain prominence…

Safe Interactive Model-Based Learning. (arXiv:1911.06556v1 [eess.SY])

Control applications present hard operational constraints. A violation of this can result in unsafe behavior. This paper introduces Safe Interactive Model Based Learning (SiMBL), a framework to refine an existing controller and a system model while operating on the real environment. SiMBL is composed of the following trainable components: a Lyapunov function, which determines a…

Tracking the circulation routes of fresh coins in Bitcoin: A way of identifying coin miners with transaction network structural properties. (arXiv:1911.06400v1 [q-fin.GN])

Bitcoin draws the highest degree of attention among cryptocurrencies, while coin mining is one of the most important fashion of profiting in the Bitcoin ecosystem. This paper constructs fresh coin circulation networks by tracking the fresh coin transfer routes with transaction referencing in Bitcoin blockchain. This paper proposes a heuristic algorithm to identifying coin miners…

Mining News Events from Comparable News Corpora: A Multi-Attribute Proximity Network Modeling Approach. (arXiv:1911.06407v1 [cs.LG])

We present ProxiModel, a novel event mining framework for extracting high-quality structured event knowledge from large, redundant, and noisy news data sources. The proposed model differentiates itself from other approaches by modeling both the event correlation within each individual document as well as across the corpus. To facilitate this, we introduce the concept of a…

Design Requirements of Generic Hand Exoskeletons and Survey of Hand Exoskeletons for Rehabilitation, Assistive or Haptic Use. (arXiv:1911.06408v1 [cs.RO])

Most current hand exoskeletons have been designed specifically for rehabilitation, assistive or haptic applications to simplify the design requirements. Clinical studies on post-stroke rehabilitation have shown that adapting assistive or haptic applications into physical therapy sessions significantly improves the motor learning and treatment process. The recent technology can lead to the creation of generic hand…

Synthetic Event Time Series Health Data Generation. (arXiv:1911.06411v1 [cs.LG])

Synthetic medical data which preserves privacy while maintaining utility can be used as an alternative to real medical data, which has privacy costs and resource constraints associated with it. At present, most models focus on generating cross-sectional health data which is not necessarily representative of real data. In reality, medical data is longitudinal in nature,…
