A two-step system for sound event localization and detection. (arXiv:1911.11373v1 [eess.AS])

Sound event detection and sound event localization requires different features from audio input signals. While sound event detection mainly relies on time-frequency patterns to distinguish different event classes, sound event localization uses magnitude or phase differences between microphones to estimate source directions. Therefore, we propose a two-step system to do sound event localization and detection.…

Optimal Design of Energy-Efficient Cell-Free Massive MIMO: Joint Power Allocation and Load Balancing. (arXiv:1911.11375v1 [cs.IT])

A large-scale distributed antenna system that serves the users by coherent joint transmission is called Cell-free Massive MIMO (multiple input multiple output). For a given user set, only a subset of the access points (APs) is likely needed to satisfy the users’ performance demands. To find a flexible and energy-efficient implementation, we minimize the total…

Income growth with high inequality implies loss of well-being: A mathematical model. (arXiv:1911.11205v1 [econ.GN])

A mathematical model of measurement of the perception of well-being for groups with increasing incomes, but proportionally unequal is proposed. Assuming that welfare grows with own income and decreases with relative inequality (income of the other concerning one’s own), possible scenarios for long-term behavior in welfare functions are concluded. Also, it is proved that a…

On the Moisil-Theodoresco operator in orthogonal curvilinear coordinates. (arXiv:1911.11211v1 [math.AP])

It is generally well understood the legitimate action of the Moisil-Theo\-do\-res\-co ope\-ra\-tor, over a quaternionic valued function defined on $\mathbb{R}^3$ (sum of a scalar and a vector field) in Cartesian coordinates, but it does not so in any orthogonal curvilinear coordinate system. This paper sheds some new light on the technical aspect of the subject.…

Modeling the diffusion of a fluid in a strained solid: a comparison between different formats. (arXiv:1911.11224v1 [cond-mat.soft])

We revise the format proposed by Bowen in [R.~M. Bowen. Int. J. Eng. Sci., 18(9):1129–1148, 1980.] to describe incompressible porous media by use of the theory of mixtures. We then show that this format is equivalent the those proposed more recently to model the diffusion of a fluid in a strained solid.

Dynamics of non cohomologically hyperbolic automorphisms of $\mathbb{C}^3$. (arXiv:1911.11231v1 [math.CV])

We study the dynamics of a family of non cohomologically hyperbolic automorphisms $f$ of $\mathbb{C}^3$. We construct a compactification $X$ of $\mathbb{C}^3$ where their extensions are algebraically stable. We finally construct canonical invariant closed positive $(1,1)$-currents for $f^*$, $f_*$ and we study several of their properties. Moreover, we study the well defined current $T_f \wedge…

On the Hewitt Stromberg dimension of product sets. (arXiv:1911.11242v1 [math.CA])

In this paper, we construct new multifractal measures, on the Euclidean space $\mathbb{R}^n$, in a similar manner to Hewitt-Stomberg measures but using the class of all $n$-dimensional half-open binary cubes of covering sets in the definition rather than the class of all balls. As an application we shall be concerned with evaluation of Hewitt-Stromberg dimension…

Unlocking the diagnostic and therapeutic potential of metagenomics. (arXiv:1911.11304v1 [q-bio.QM])

During the past decade, rapid advancements in sequencing technologies have enabled the study of human-associated microbiomes at an unprecedented scale. Metagenomics, specifically, is emerging as a clinical tool to identify the agents of infection, track the spread of diseases, and surveil potential pathogens. Yet, despite advances in high-throughput sequencing technologies and bioinformatics algorithms, metagenomics still…
