Advanced Materials Technologies, EarlyView.Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Unlocking Terahertz Steganography: Authentication of Hidden Images in Flexible Media
Advanced Materials Technologies, EarlyView.Hidden information in multilayered devices, such as steganographic portraits, is detected and authenticated using reflection‐mode terahertz time‐domain imaging. Image reconstruction relies on a dedicated figure‐of‐merit obtained by integrating the signal intensity over the time‐window associated with the reflection from the metallic mirror backing the ...

On an integral equation with a bessel function kernel
Journal of Integral Equations and Applications, 1988 The author obtains the solution of the integral equation \(g(x)=\int^{\infty}_{0}J^ 2_ x(y)f(y)dy,\) where g(x) is a known function, \(J_ x(y)\) is the Bessel function of order x and f(y) is the unknown function. The solution obtained is: \[ f(y)=y\int^{\infty}_{0}\tau J_ 0(y\tau)\{\int^{\infty}_{0}G(x)\cos xt dx\}d\tau,\quad y\geq 0, \] where \(\tau ...
