two-dimensional torus. In particular, we construct invariant Gibbs measures for
the renormalized so-called Wick ordered NLW. We then prove weak universality of
the Wick ordered NLW, showing that the Wick ordered NLW naturally appears as a

Topological Analysis and Synthesis of Structures related to Certain Classes of K-Geodetic Computer Networks | A fundamental characteristic of computer networks is their topological
structure. The question of the description of the structural characteristics of
computer networks represents a problem that is not completely solved. Search

selected paramete... | 1 | 0 | 0 | 0 | 0 | 0 |
A distributed-memory hierarchical solver for general sparse linear systems | We present a parallel hierarchical solver for general sparse linear systems
on distributed-memory machines. For large-scale problems, this fully algebraic
algorithm is faster and more memory-efficient than sparse direct solvers
because it exploits the low-rank structure of fill-in blocks. Depending on the
accuracy of... | 1 | 0 | 0 | 0 | 0 | 0 |
Quasar: Datasets for Question Answering by Search and Reading | We present two new large-scale datasets aimed at evaluating systems designed

Choreographic and Somatic Approaches for the Development of Expressive Robotic Systems | As robotic systems are moved out of factory work cells into human-facing
environments questions of choreography become central to their design,
placement, and application. With a human viewer or counterpart present, a

form factor by human... | 1 | 0 | 0 | 0 | 0 | 0 |
Development of verification system of socio-demographic data of virtual community member | The important task of developing verification system of data of virtual

Demonstration of an efficient, photonic-based astronomical spectrograph on an 8-m telescope | We demonstrate for the first time an efficient, photonic-based astronomical
spectrograph on the 8-m Subaru Telescope. An extreme adaptive optics system is
combined with pupil apodiziation optics to efficiently inject light directly
into a single-mode fiber, which feeds a compact cross-dispersed spectrograph

A Game of Random Variables | This paper analyzes a simple game with $n$ players. We fix a mean, $\mu$, in
the interval $[0, 1]$ and let each player choose any random variable
distributed on that interval with the given mean. The winner of the zero-sum
game is the player whose random variable has the highest realization. We show
that the position... | 1 | 0 | 0 | 0 | 0 | 0 |
Parallel Structure from Motion from Local Increment to Global Averaging | In this paper, we tackle the accurate and consistent Structure from Motion
(SfM) problem, in particular camera registration, far exceeding the memory of a
single computer in parallel. Different from the previous methods which

final reconstru... | 1 | 0 | 0 | 0 | 0 | 0 |

Negative electronic compressibility and nanoscale inhomogeneity in ionic-liquid gated two-dimensional superconductors | When the electron density of highly crystalline thin films is tuned by
chemical doping or ionic liq- uid gating, interesting effects appear including
unconventional superconductivity, sizeable spin-orbit coupling, competition
with charge-density waves, and a debated low-temperature metallic state that
seems to avoid ... | 0 | 1 | 0 | 0 | 0 | 0 |
Symbolic Music Genre Transfer with CycleGAN | Deep generative models such as Variational Autoencoders (VAEs) and Generative

several generators and some form of cycle consistency loss have been among the

Methodology for Multi-stage, Operations- and Uncertainty-Aware Placement and Sizing of FACTS Devices in a Large Power Transmission System | We develop new optimization methodology for planning installation of Flexible

PC Proxy: A New Method of Dynamical Tracer Reconstruction | A detailed development of the principal component proxy method of dynamical

Magnetic Correlations in the Two-dimensional Repulsive Fermi Hubbard Model | The repulsive Fermi Hubbard model on the square lattice has a rich phase
diagram near half-filling (corresponding to the particle density per lattice
site $n=1$): for $n=1$ the ground state is an antiferromagnetic insulator, at
$0.6 < n \lesssim 0.8$, it is a $d_{x^2-y^2}$-wave superfluid (at least for

Bridge type classification: supervised learning on a modified NBI dataset | A key phase in the bridge design process is the selection of the structural

Automatic Question-Answering Using A Deep Similarity Neural Network | Automatic question-answering is a classical problem in natural language
processing, which aims at designing systems that can automatically answer a

answers are embedd... | 1 | 0 | 0 | 0 | 0 | 0 |
Long ties accelerate noisy threshold-based contagions | Changes to network structure can substantially affect when and how widely new
ideas, products, and conventions are adopted. In models of biological

contagion, such as those ... | 1 | 0 | 0 | 0 | 0 | 0 |
Detecting topological transitions in two dimensions by Hamiltonian evolution | We show that the evolution of two-component particles governed by a

Indoor Frame Recovery from Refined Line Segments | An important yet challenging problem in understanding indoor scene is
recovering indoor frame structure from a monocular image. It is more difficult

Fairly Allocating Contiguous Blocks of Indivisible Items | In this paper, we study the classic problem of fairly allocating indivisible

forms a contiguous block on the line. While allocations satisfying the
classical fairn... | 1 | 0 | 0 | 0 | 0 | 0 |
