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

Using Microphone Arrays to Detect Moving Vehicle Velocity
Archives of Acoustics, 2013 The noise of motor vehicles is one of the most important problems as regards to pollution on main roads. However, this unpleasant characteristic could be used to determine vehicle speed by external observers.

Laser-Based Command Injection Attacks on Voice-Controlled Microphone Arrays
Transactions on Cryptographic Hardware and Embedded SystemsVoice-controlled (VC) systems, such as mobile phones and smart speakers, enable users to operate smart devices through voice commands. Previous works (e.g., LightCommands) show that attackers can trigger VC systems to respond to various audio commands ...

Effect of wind and temperature gradients on received acoustic energy [PDF]
The effect of refraction due to wind and temperature gradients on energy received from low flying aircraft is examined. A series of helicopter and jet flyby's were recorded with a microphone array on two separate days, each with distinctly different ...

Small, EarlyView.An automated MATLAB framework for inverse photoacoustic analysis enables precise thermal characterization of complex multilayer films. Application to electrodeposited CuxSe reveals a stoichiometry‐dependent thermal conductivity governed by lattice anharmonicity, not grain‐size scattering, in these superionic materials. ABSTRACT Precise determination of

One eight of a sphere microphone array
, 2020 Spherical microphone arrays are widespread nowadays, especially with the advent of techniques for decomposing acoustic fields on the basis of spherical harmonics (i.e. Ambisonics). However, in these approaches, the corresponding arrays require a quadratically increasing number of microphones as the degree of the components to be estimated increases ...
