Weyl metrics and Wiener-Hopf factorization

Journal of High Energy Physics, 2020
We consider the Riemann-Hilbert factorization approach to the construction of Weyl metrics in four space-time dimensions. We present, for the first time, a rigorous proof of the remarkable fact that the canonical Wiener-Hopf factorization of a matrix ...

Observations on holographic aspects of four-dimensional asymptotically flat N $$ \mathcal{N} $$ = 2 black holes

Journal of High Energy Physics, 2022
In this note, we explore holographic attributes of four-dimensional near-extremal Reissner-Nordstrom black hole solutions in ungauged N $$ \mathcal{N} $$ = 2 supergravity theories at the two-derivative level by recasting them as a specific first-order ...

Chaos on Fuzzy Dynamical Systems

, 2021
Given a continuous map f:X→X on a metric space, it induces the maps f¯:K(X)→K(X), on the hyperspace of nonempty compact subspaces of X, and f^:F(X)→F(X), on the space of normal fuzzy sets, consisting of the upper semicontinuous functions u:X→[0,1] with ...

An integrated MVDR beamformer for speech enhancement using a local microphone array and external microphones

EURASIP Journal on Audio, Speech, and Music Processing, 2021
An integrated version of the minimum variance distortionless response (MVDR) beamformer for speech enhancement using a microphone array has been recently developed, which merges the benefits of imposing constraints defined from both a relative transfer ...

Cascade algorithms for combined acoustic feedback cancelation and noise reduction

EURASIP Journal on Audio, Speech, and Music Processing, 2023
This paper presents three cascade algorithms for combined acoustic feedback cancelation (AFC) and noise reduction (NR) in speech applications. A prediction error method (PEM)-based adaptive feedback cancelation (PEM-based AFC) algorithm is used for the ...

An approach to BPS black hole microstate counting in an N = 2 STU model

Journal of High Energy Physics, 2020
We consider four-dimensional dyonic single-center BPS black holes in the N = 2 STU model of Sen and Vafa. By working in a region of moduli space where the real part of two of the three complex scalars S, T , U are taken to be large, we evaluate the ...

Arithmetic of decay walls through continued fractions: a new exact dyon counting solution in N $$ \mathcal{N} $$ = 4 CHL models

Journal of High Energy Physics, 2021
We use continued fractions to perform a systematic and explicit characterization of the decays of two-centred dyonic black holes in 4D N $$ \mathcal{N} $$ = 4 heterotic ℤ N CHL models.
