Z-transformstabilityroot-mapThis chapter introduces 2-D difference equations and the Z transform including recursive filter stability theorems. It is a generalization of the 1-D Z-transform used in the analysis and synthesis of 1-D linear constant coefficient difference equation-based systems. In ...
The approximation of the DST-VII can be used for the transform optimization. At the hardware level, this method can provide a gain in power consumption, logic resources use and speed. In this paper, a unifed two-dimensional transform architecture that enables exact and approximate DST-VII ...

Based on first-principles calculations and tight-binding model analysis, we propose monolayer graphdiyne as a candidate material for a two-dimensional higher-order topological insulator protected by inversion symmetry. Despite the absence of chiral symmetry, the higher-order topology of monolayer graphdiyne...
Perovskite solar cells (PSCs) offer low costs and high power conversion efficiency. However, the lack of long-term stability, primarily stemming from the interfacial defects and the susceptible metal electrodes, hinders their practical application. In the past few years, two-dimensional (2D) materia...

The inverse problem for the two-dimensional Schrdinger operator on the data from one energy level is solved in a special class of "finite-zone" or "algebraic" operators. This class seems to be dense among all smooth periodic Schrdinger operators. Evolutional equations associated with this problem...
The author presents a two-dimensional recursive fast Fourier transform (RFFT) which consists of two recursive algorithms and a revised fast Fourier transform in the recursive process. This algorithm is applied to image processing as an example of 2-D signal processing. Compared with a standard FFT...
we improve >2-fold spatially and >10-fold temporally the resolution of planar cellular force probing compared to its related conventional modalities by combining fast two-dimensional total internal reflection fluorescence super-resolution structured illumination microscopy and traction force microscopy. This ...
Below the critical velocity, we can manipulate the bound quasiparticle dispersion curves by changing the direction and amplitude of the superflow along the surface, allowing us to create a non-equilibrium state within the two-dimensional superfluid. The crossbar trajectories used for this purpose are...
