An FPTAS for the Knapsack Problem with Parametric Weights | In this paper, we investigate the parametric weight knapsack problem, in
which the item weights are affine functions of the form $w_i(\lambda) = a_i +
\lambda \cdot b_i$ for $i \in \{1,\ldots,n\}$ depending on a real-valued
parameter $\lambda$. The aim is to provide a solution for all values of the
parameter. It is w... | 1 | 0 | 1 | 0 | 0 | 0 |
Mellin and Wiener-Hopf operators in a non-classical boundary value problem describing a Lévy process | Markov processes are well understood in the case when they take place in the
whole Euclidean space. However, the situation becomes much more complicated if
a Markov process is restricted to a domain with a boundary, and then a
satisfactory theory only exists for processes with continuous trajectories.

Long-term photometric behavior of the eclipsing cataclysmic variable V729 Sgr | We present the analysis results of an eclipsing cataclysmic variable (CV)
V729 Sgr, based on our observations and AAVSO data. Some outburst parameters
were determined such as outburst amplitude ($A_{n}$) and recurrence time
($T_{n}$), and then the relationship between $A_{n}$ and $T_{n}$ is discussed.

SPUX: Scalable Particle Markov Chain Monte Carlo for uncertainty quantification in stochastic ecological models | Calibration of individual based models (IBMs), successful in modeling complex
ecological dynamical systems, is often performed only ad-hoc. Bayesian
inference can be used for both parameter estimation and uncertainty
quantification, but its successful application to realistic scenarios has been
hindered by the comple... | 1 | 0 | 0 | 1 | 0 | 0 |
A Social Network Analysis Framework for Modeling Health Insurance Claims Data | Health insurance companies in Brazil have their data about claims organized
having the view only for providers. In this way, they loose the physician view
and how they share patients. Partnership between physicians can view as a

health insur... | 1 | 0 | 0 | 0 | 0 | 0 |
Congruences for Restricted Plane Overpartitions Modulo 4 and 8 | In 2009, Corteel, Savelief and Vuletić generalized the concept of
overpartitions to a new object called plane overpartitions. In recent work, the
author considered a restricted form of plane overpartitions called $k$-rowed
plane overpartions and proved a method to obtain congruences for these and
other types of combi... | 0 | 0 | 1 | 0 | 0 | 0 |
AndroVault: Constructing Knowledge Graph from Millions of Android Apps for Automated Analysis | Data driven research on Android has gained a great momentum these years. The
abundance of data facilitates knowledge learning, however, also increases the

Universal and generalizable restoration strategies for degraded ecological networks | Humans are increasingly stressing ecosystems via habitat destruction, climate
change and global population movements leading to the widespread loss of

Information transmission and signal permutation in active flow networks | Recent experiments show that both natural and artificial microswimmers in
narrow channel-like geometries will self-organise to form steady, directed
flows. This suggests that networks of flowing active matter could function as
novel autonomous microfluidic devices. However, little is known about how
information propa... | 1 | 1 | 0 | 0 | 0 | 0 |
Heuristic Framework for Multi-Scale Testing of the Multi-Manifold Hypothesis | When analyzing empirical data, we often find that global linear models
overestimate the number of parameters required. In such cases, we may ask
whether the data lies on or near a manifold or a set of manifolds (a so-called
multi-manifold) of lower dimension than the ambient space. This question can be
phrased as a (... | 0 | 0 | 0 | 1 | 0 | 0 |
Kitting in the Wild through Online Domain Adaptation | Technological developments call for increasing perception and action

Event Analysis of Pulse-reclosers in Distribution Systems Through Sparse Representation | The pulse-recloser uses pulse testing technology to verify that the line is

Projected Power Iteration for Network Alignment | The network alignment problem asks for the best correspondence between two

Effects of Interactions on Dynamic Correlations of Hard-Core Bosons at Finite Temperatures | We investigate how dynamic correlations of hard-core bosonic excitation at
finite temperature are affected by additional interactions besides the

The Frechet distribution: Estimation and Application an Overview | In this article, we consider the problem of estimating the parameters of the

Prediction of Sea Surface Temperature using Long Short-Term Memory | This letter adopts long short-term memory(LSTM) to predict sea surface

An Operational Framework for Specifying Memory Models using Instantaneous Instruction Execution | There has been great progress recently in formally specifying the memory

Statistical Challenges in Modeling Big Brain Signals | Brain signal data are inherently big: massive in amount, complex in
