Simulations of second order microphones in audio coding

open access: yes, 2011
6 pagesThe method of array processing involves the use of multiple microphones to receive a signal carried by propagating waves. Microphone arrays have a variety of applications such as sonars, radars and acoustic tomography.

Genome‐Wide Assessment Reveals Ancestral Differences in Homozygosity Patterns Potentially Linked to Parkinson's Disease Etiology

open access: yesMovement Disorders, EarlyView.
Abstract Background Recessive genetic variation and extended runs of homozygosity (ROHs) may contribute to the unexplained heritability of Parkinson's disease (PD), particularly in diverse and understudied populations. Objective We conducted the first large‐scale, multi‐ancestral investigation of PD to examine the impact of genome‐wide homozygosity on ...

Flexible Beampattern Design Algorithm for Spherical Microphone Arrays

open access: yesIEEE Access, 2019
Specific beampatterns of spherical microphone arrays (SMAs) are designed for different noise scenarios. The standard beampattern usually achieves optimum value in one of the performance indicators.

Nonlocal active sound control for composite regions

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
In the active sound control problem, additional sound sources, known as control sources, are implemented at the perimeter of a protected domain. The control sources can generate secondary sound inside the shielded domain, which attenuates incoming noise. This leads to an inverse source problem.

MilliSonic: Pushing the Limits of Acoustic Motion Tracking

open access: yes, 2019
Recent years have seen interest in device tracking and localization using acoustic signals. State-of-the-art acoustic motion tracking systems however do not achieve millimeter accuracy and require large separation between microphones and speakers, and as

Emerging Upper Extremity Muscle Ultrasound Patterns as a Diagnostic Aid in TTN‐Related Myopathies

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Biallelic pathogenic variants in TTN cause rare forms of early‐onset myopathy, manifesting with variable severity, distribution, and progression of muscle weakness, often associated with respiratory insufficiency and potentially cardiomyopathy. The large size of TTN and phenotypic heterogeneity in TTN‐related myopathy (TTN‐RM)

Sliding Mode Control in Aerospace Applications: A Survey

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...
