FIR Filter Implementation Based on the RNS with Diminished-1 Encoded Channel

open access: yesInternational Journal of Advances in Telecommunications, Electrotechnics, Signals and Systems, 2013
A technique, based on the residue number system (RNS) with diminished-1 encoded channel, has being used for implementing a finite impulse response (FIR) digital filter.

Beaver dam analogues increase amphibian breeding occupancy and bat activity

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Beavers are ecosystem engineers that can create ponds, increase stream complexity, and enhance biodiversity. To mimic these and other effects, restoration practitioners increasingly install beaver dam analogues (BDAs) in degraded streams.

Distinctive neurophysiological correlates of sound onset and offset perception in humans

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Electroencephalography (EEG) recordings were obtained from participants listening to successive pairs of 1‐2 s noises in a silent background (Study 1) or successive pairs 1‐2 s silent gaps in a noise background (Study 2). Participants heard the same stimuli in the context of either a duration discrimination task (identifying ...

An Area-Efficient TMR Architecture Inspired From Fast FIR Algorithm for Fault Tolerance

open access: yesIEEE Access
High-end commercial silicon chips used in aerospace and other industries utilize technology nodes at deep sub-micron levels. Efforts are underway to assess the feasibility of integrating even smaller nano-scale devices for secure communication, high ...

A new class of two-channel biorthogonal filter banks and wavelet bases [PDF]

open access: yes, 1995
We propose a novel framework for a new class of two-channel biorthogonal filter banks. The framework covers two useful subclasses: i) causal stable IIR filter banks. ii) linear phase FIR filter banks.

Optimizing Selective RF Pulses for Enhanced Signal Stability in Turbo Spin Echo Using a Differentiable Extended Phase Graph Model

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 214-226, July 2026.
ABSTRACT Purpose To improve slice profile consistency across echo trains in turbo spin echo (TSE) imaging, thereby reducing image blurring and increasing the accuracy of multi echo spin echo T2$$ {T}_2 $$ mapping. Methods Excitation and refocusing RF pulses were optimized for TSE using a differentiable extended phase graph model that incorporates the ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1091-1119, June 2026.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Cascaded integrator comb filters with smoothly varying coefficients for reduced delay in synchrotron feedback loops

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2005
The Rapid Cycling Synchrotron (RCS) of the J-PARC complex in Tokai, Japan, is designed to accelerate a high intensity proton beam from 181 MeV, and later 400 MeV to 3 GeV in 20 ms within the 40 ms machine cycle. The beam power up to 1 MW demands a stable

Spatial Fluidity and the Outcomes of Entrepreneurial Ecosystems: An Analysis Based on Investment Flows

open access: yesGrowth and Change, Volume 57, Issue 2, June 2026.
ABSTRACT The spatiality of Entrepreneurial Ecosystems (EE) has become a topic of recent interest in literature. Traditionally based on a regionally‐bounded appraisal of the contextual conditions leading up to entrepreneurial activity, EE research is facing a shift toward the inclusion of more fine‐grained territorial approaches that accommodate complex

Compactly Supported Wavelets Derived From Legendre Polynomials: Spherical Harmonic Wavelets [PDF]

open access: yes, 2015
A new family of wavelets is introduced, which is associated with Legendre polynomials. These wavelets, termed spherical harmonic or Legendre wavelets, possess compact support.
