Contagions in Social Networks: Effects of Monophilic Contagion, Friendship Paradox and Reactive Networks | We consider SIS contagion processes over networks where, a classical

scatterplot, where each axis corresponds to the rank-frequency a term occurs in
a category of documents. Through a tie-breaking strategy, the tool is able to

Tight contact structures on Seifert surface complements | We consider complements of standard Seifert surfaces of special alternating
links. On these handlebodies, we use Honda's method to enumerate those tight
contact structures whose dividing sets are isotopic to the link, and find their
number to be the leading coefficient of the Alexander polynomial. The Euler
classes o... | 0 | 0 | 1 | 0 | 0 | 0 |
Modular invariant representations of the $\mathcal{N}=2$ superconformal algebra | We compute the modular transformation formula of the characters for a certain

$\mathcal{N}=2$ vertex operator superalgebra of central charge

Distributed Kernel K-Means for Large Scale Clustering | Clustering samples according to an effective metric and/or vector space
representation is a challenging unsupervised learning task with a wide spectrum

kernelized version have still a wide audience because of their conceptual
simplicity and efficac... | 0 | 0 | 0 | 1 | 0 | 0 |
The Origin of Solar Filament Plasma Inferred from in situ Observations of Elemental Abundances | Solar filaments/prominences are one of the most common features in the
corona, which may lead to energetic coronal mass ejections (CMEs) and flares
when they erupt. Filaments are about one hundred times cooler and denser than
the coronal material, and physical understanding of their material origin
remains controvers... | 0 | 1 | 0 | 0 | 0 | 0 |
Distributed Stochastic Optimization via Adaptive SGD | Stochastic convex optimization algorithms are the most popular way to train
machine learning models on large-scale data. Scaling up the training process of
these models is crucial, but the most popular algorithm, Stochastic Gradient
Descent (SGD), is a serial method that is surprisingly hard to parallelize. In

Bilipschitz Equivalence of Trees and Hyperbolic Fillings | We combine conditions found in [Wh] with results from [MPR] to show that
quasi-isometries between uniformly discrete bounded geometry spaces that
satisfy linear isoperimetric inequalities are within bounded distance to
bilipschitz equivalences. We apply this result to regularly branching trees and
hyperbolic fillings... | 0 | 0 | 1 | 0 | 0 | 0 |
On the contribution of thermal excitation to the total 630.0 nm emissions in the northern cusp ionosphere | Direct impact excitation by precipitating electrons is believed to be the
main source of 630.0 nm emissions in the cusp ionosphere. However, this paper
investigates a different source, 630.0 emissions caused by thermally excited
atomic oxygen O$(^{1}$D) when high electron temperature prevail in the cusp. On

Dose finding for new vaccines: the role for immunostimulation/immunodynamic modelling | Current methods to optimize vaccine dose are purely empirically based,
whereas in the drug development field, dosing determinations use far more

On Learning Mixtures of Well-Separated Gaussians | We consider the problem of efficiently learning mixtures of a large number of
spherical Gaussians, when the components of the mixture are well separated. In
the most basic form of this problem, we are given samples from a uniform

Sylvester's Problem and Mock Heegner Points | We prove that if $p \equiv 4,7 \pmod{9}$ is prime and $3$ is not a cube
modulo $p$, then both of the equations $x^3+y^3=p$ and $x^3+y^3=p^2$ have a
solution with $x,y \in \mathbb{Q}$.

Community Detection in the Network of German Princes in 1225: a Case Study | Many social networks exhibit some underlying community structure. In

Statistical study of auroral omega bands | The presence of very few statistical studies on auroral omega bands motivated

Inter-site pair superconductivity: origins and recent validation experiments | The challenge of understanding high-temperature superconductivity has led to

Non-standard FDTD implementation of the Schrödinger equation | In this work, we apply the Cole's non-standard form of the FDTD to solve the

electron. The non-... | 0 | 1 | 0 | 0 | 0 | 0 |
The magnetic and electronic properties of Oxyselenides - influence of transition metal ions and lanthanides | Magnetic oxyselenides have been the topic of research for several decades

interest in the oxyselenides ... | 0 | 1 | 0 | 0 | 0 | 0 |
Localizing the Object Contact through Matching Tactile Features with Visual Map | This paper presents a novel framework for integration of vision and tactile
