to detect gravitational wave events at redshifts far beyond any detectable
electromagnetic sources. We show that if the observed event rate is greater
than one event per year at redshifts z > 40, then the probability distribution
of primordia... | 0 | 1 | 0 | 0 | 0 | 0 |
The altmetric performance of publications authored by Brazilian researchers: analysis of CNPq productivity scholarship holders | The present work seeks to analyse the altmetric performance of Brazilian
publications authored by researchers who are productivity scholarship holders

The Impact of Information Dissemination on Vaccinating Epidemics in Multiplex Networks | The impact of information dissemination on epidemic control essentially
affects individual behaviors. Among the information-driven behaviors,
vaccination is determined by the cost-related factors, and the correlation with
information dissemination is not clear yet. To this end, we present a model to
integrate the inf... | 0 | 0 | 0 | 0 | 1 | 0 |
Why Interpretability in Machine Learning? An Answer Using Distributed Detection and Data Fusion Theory | As artificial intelligence is increasingly affecting all parts of society and
life, there is growing recognition that human interpretability of machine
learning models is important. It is often argued that accuracy or other similar
generalization performance metrics must be sacrificed in order to gain
interpretabilit... | 0 | 0 | 0 | 1 | 0 | 0 |
Online Estimation and Adaptive Control for a Class of History Dependent Functional Differential Equations | This paper presents sufficient conditions for the convergence of online
estimation methods and the stability of adaptive control strategies for a class

The Kinematics of the Permitted C II $λ$ 6578 Line in a Large Sample of Planetary Nebulae | We present spectroscopic observations of the C II $\lambda$6578 permitted
line for 83 lines of sight in 76 planetary nebulae at high spectral resolution,
most of them obtained with the Manchester Echelle Spectrograph on the 2.1\,m
telescope at the Observatorio Astronómico Nacional on the Sierra San Pedro

From parabolic-trough to metasurface-concentrator | Metasurfaces are promising tools towards novel designs for flat optics
applications. As such their quality and tolerance to fabrication imperfections
need to be evaluated with specific tools. However, most such tools rely on the
geometrical optics approximation and are not straightforwardly applicable to
metasurfaces... | 0 | 1 | 0 | 0 | 0 | 0 |
Correspondence Theorem between Holomorphic Discs and Tropical Discs on K3 Surfaces | We prove that the open Gromov-Witten invariants on K3 surfaces satisfy the
Kontsevich-Soibelman wall-crossing formula. One one hand, this gives a
geometric interpretation of the slab functions in Gross-Siebert program. On the
other hands, the open Gromov-Witten invariants coincide with the weighted
counting of tropic... | 0 | 0 | 1 | 0 | 0 | 0 |
A review and comparative study on functional time series techniques | This paper reviews the main estimation and prediction results derived in the
context of functional time series, when Hilbert and Banach spaces are
considered, specially, in the context of autoregressive processes of order one
(ARH(1) and ARB(1) processes, for H and B being a Hilbert and Banach space,
respectively). P... | 0 | 0 | 1 | 1 | 0 | 0 |
Surface depression with double-angle geometry during the discharge of close-packed grains from a silo | When rough grains in standard packing conditions are discharged from a silo,
a conical depression with a single slope is formed at the surface. We observed
that the increase of the volume fraction generates a more complex depression
characterized by two angles of discharge: a lower angle close to the one
measured for... | 0 | 1 | 0 | 0 | 0 | 0 |
Answer Set Programming for Non-Stationary Markov Decision Processes | Non-stationary domains, where unforeseen changes happen, present a challenge

Space-Bounded OTMs and REG$^{\infty}$ | An important theorem in classical complexity theory is that LOGLOGSPACE=REG,
i.e. that languages decidable with double-logarithmic space bound are regular.
We consider a transfinite analogue of this theorem. To this end, we introduce
deterministic ordinal automata (DOAs), show that they satisfy many of the basic

Linear-time approximation schemes for planar minimum three-edge connected and three-vertex connected spanning subgraphs | We present the first polynomial-time approximation schemes, i.e., (1 +

three-vertex connected spanning subgraph problem in undirected planar graphs.

Towards Wi-Fi AP-Assisted Content Prefetching for On-Demand TV Series: A Reinforcement Learning Approach | The emergence of smart Wi-Fi APs (Access Point), which are equipped with huge

startup delay and smooth playback). One important research interest in this

Schematic Polymorphism in the Abella Proof Assistant | The Abella interactive theorem prover has proven to be an effective vehicle

Representations of weakly multiplicative arithmetic matroids are unique | An arithmetic matroid is weakly multiplicative if the multiplicity of at
least one of its bases is equal to the product of the multiplicities of its
elements. We show that if such an arithmetic matroid can be represented by an
integer matrix, then this matrix is uniquely determined. This implies that the

Memory Efficient Max Flow for Multi-label Submodular MRFs | Multi-label submodular Markov Random Fields (MRFs) have been shown to be
solvable using max-flow based on an encoding of the labels proposed by
Ishikawa, in which each variable $X_i$ is represented by $\ell$ nodes (where
$\ell$ is the number of labels) arranged in a column. However, this method in
general requires $2... | 1 | 0 | 0 | 0 | 0 | 0 |
Double Covers of Cartan Modular Curves | We present a strategy to obtain explicit equations for the modular double
covers associated respectively to both a split and a non-split Cartan subgroup
of $\text{GL}_2(\mathbb F_{p})$ with $p$ prime. Then we apply it successfully
to the level $13$ case.
