Penetrating a Social Network: The Follow-back Problem | Modern threats have emerged from the prevalence of social networks. Hostile
actors, such as extremist groups or foreign governments, utilize these networks
to run propaganda campaigns with different aims. For extremists, these
campaigns are designed for recruiting new members or inciting violence. For
foreign governm... | 1 | 0 | 0 | 1 | 0 | 0 |
Universality of density waves in p-doped La2CuO4 and n-doped Nd2CuO4+y | The contribution of $O^{2-}$ ions to antiferromagnetism in
$La_{2-x}Ae_xCuO_4$ ($Ae = Sr, Ba)$ is highly sensitive to doped holes. In
contrast, the contribution of $Cu^{2+}$ ions to antiferromagnetism in
$Nd_{2-x}Ce_xCuO_{4+y}$ is much less sensitive to doped electrons. The
difference causes the precarious and, respe... | 0 | 1 | 0 | 0 | 0 | 0 |
The perceived assortativity of social networks: Methodological problems and solutions | Networks describe a range of social, biological and technical phenomena. An
important property of a network is its degree correlation or assortativity,
describing how nodes in the network associate based on their number of
connections. Social networks are typically thought to be distinct from other
networks in being ... | 1 | 0 | 0 | 1 | 0 | 0 |
Generalized Sheet Transition Conditions (GSTCs) for a Metascreen -- A Fishnet Metasurface | We used a multiple-scale homogenization method to derive generalized sheet
transition conditions (GSTCs) for electromagnetic fields at the surface of a
metascreen---a metasurface with a "fishnet" structure. These surfaces are
characterized by periodically-spaced arbitrary-shaped apertures in an otherwise
relatively i... | 0 | 1 | 0 | 0 | 0 | 0 |
$k^{τ,ε}$-anonymity: Towards Privacy-Preserving Publishing of Spatiotemporal Trajectory Data | Mobile network operators can track subscribers via passive or active

The Taipan Galaxy Survey: Scientific Goals and Observing Strategy | Taipan is a multi-object spectroscopic galaxy survey starting in 2017 that
will cover 2pi steradians over the southern sky, and obtain optical spectra for
about two million galaxies out to z<0.4. Taipan will use the newly-refurbished
1.2m UK Schmidt Telescope at Siding Spring Observatory with the new TAIPAN

The Externalities of Exploration and How Data Diversity Helps Exploitation | Online learning algorithms, widely used to power search and content

whether the proces... | 0 | 0 | 0 | 1 | 0 | 0 |
Life-span of blowup solutions to semilinear wave equation with space-dependent critical damping | This paper is concerned with the blowup phenomena for initial value problem
of semilinear wave equation with critical space-dependent damping term

problem and to provide a sharp estimate for lifespan for such a solution when

Invariant submanifolds of (LCS)n-Manifolds with respect to quarter symmetric metric connection | The object of the present paper is to study invariant submanifolds of

shown that the mean curvature of an invariant submanifold of (LCS)n-manifold
with respect to quarter symmetric metric connection and Levi-Civita connection
are equal. An ex... | 0 | 0 | 1 | 0 | 0 | 0 |
Iterated filtering methods for Markov process epidemic models | Dynamic epidemic models have proven valuable for public health decision
makers as they provide useful insights into the understanding and prevention of

An Algebraic-Combinatorial Proof Technique for the GM-MDS Conjecture | This paper considers the problem of designing maximum distance separable
(MDS) codes over small fields with constraints on the support of their
generator matrices. For any given $m\times n$ binary matrix $M$, the GM-MDS
conjecture, due to Dau et al., states that if $M$ satisfies the so-called MDS
condition, then for ... | 1 | 0 | 0 | 0 | 0 | 0 |
The Word Problem of $\mathbb{Z}^n$ Is a Multiple Context-Free Language | The \emph{word problem} of a group $G = \langle \Sigma \rangle$ can be
defined as the set of formal words in $\Sigma^*$ that represent the identity in
$G$. When viewed as formal languages, this gives a strong connection between
classes of groups and classes of formal languages. For example, Anisimov showed

Rigorous proof of the Boltzmann-Gibbs distribution of money on connected graphs | Models in econophysics, i.e., the emerging field of statistical physics that

Stochastic population dynamics in spatially extended predator-prey systems | Spatially extended population dynamics models that incorporate intrinsic

Learning Policies for Markov Decision Processes from Data | We consider the problem of learning a policy for a Markov decision process
consistent with data captured on the state-actions pairs followed by the
policy. We assume that the policy belongs to a class of parameterized policies
which are defined using features associated with the state-action pairs. The
features are k... | 1 | 0 | 1 | 1 | 0 | 0 |
Expecting the Unexpected: Training Detectors for Unusual Pedestrians with Adversarial Imposters | As autonomous vehicles become an every-day reality, high-accuracy pedestrian

The sequence of open and closed prefixes of a Sturmian word | A finite word is closed if it contains a factor that occurs both as a prefix
and as a suffix but does not have internal occurrences, otherwise it is open.

sequence whose $n$-th element is $0$ if the prefix of length $n$ of the word is

Capital Regulation under Price Impacts and Dynamic Financial Contagion | We construct a continuous time model for price-mediated contagion

On seaweed subalgebras and meander graphs in type D | In 2000, Dergachev and Kirillov introduced subalgebras of "seaweed type" in

"seaweeds", have been defined by Panyushev (2001) for arbitrary reductive Lie

Singular Riemannian flows and characteristic numbers | Let $M$ be an even-dimensional, oriented closed manifold. We show that the

Transformation Models in High-Dimensions | Transformation models are a very important tool for applied statisticians and
