International Journal of Circuit Theory and Applications, EarlyView.This work explores the conversion from residues to binary representation in RNS using the Chinese remainder theorem (CRT) or mixed radix conversion (MRC) algorithms. The proposed approach relocates CRT multiplicative inverses to the arithmetic stage without extra cost, improving scalability while achieving speedups over state‐of‐the‐art MRC ...

Role of anticausal inverses in multirate filter-banks. I. System-theoretic fundamentals [PDF]
, 1995 In a maximally decimated filter bank with identical decimation ratios for all channels, the perfect reconstructibility property and the nature of reconstruction filters (causality, stability, FIR property, and so on) depend on the properties of the ...

Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone
Ecography, EarlyView.This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.

On power-complementary FIR filters [PDF]
, 1985 Conditions are derived, under which two linear-phase FIR filter transfer functions H(z)and G(z) have the power-complementary property, i.e., |H(e^{j omega})|^{2} + |G(e^{jomega})|^{2} = 1.

Seizure forecasting with epilepsy cycles: On the causality of forecasting pipelines
Epilepsia, EarlyView.Abstract Objective Seizure risk is modulated by multiscale brain rhythms. Previous studies using cycles in electroencephalography, heart rate, and wearable data suggest the possibility of forecasting seizures days in advance. However, they commonly rely on methods requiring (days of) information from time points beyond the moment of forecast (noncausal

Constructing a quadratic-exponential FIR-filter with an extended frequency response midrange [PDF]
Компьютерная оптика, 2018 This article is concerned with synthesizing filter with finite impulse response (FIR-filters) employed to correct radially symmetric distortions such as defocusing. We propose a new parametric class of finite impulse response filters (FIR-filters) based

Low complexity two-dimensional digital filters using unconstrained SPT term allocation [PDF]
, 1996 Previous work by the authors has demonstrated how circularly symmetric and diamond-shaped low-pass linear phase 2-D FIR filters can be designed using coefficients comprising the sum or difference of two signed power-of-two (SPT) terms.

An efficient FIR filter architecture [PDF]
1993 IEEE International Symposium on Circuits and Systems, 2002 An efficient architecture for finite impulse response (FIR) filters is described. By exploiting the reduced complexity made possible by the use of sparse powers-of-two coefficients, an FIR filter tap can be implemented with only 2B full adders and 2B (or 4B) latches, where B is the intermediate wordlength.

Epilepsia, EarlyView.Cong Fu et al. demonstrate that glymphatic system dysfunction is linked to enhanced inhibitory cortical activity using diffusion MRI and EEG. These findings highlight a mechanistic link between perivascular fluid dynamics and neuronal activity, suggesting a role for glymphatic function in maintaining cortical stability in epilepsy.
