NMR in Biomedicine, Volume 39, Issue 8, August 2026.Ultrashort and zero echo time (UTE and ZTE) MRI techniques generate functional contrast through inflow effects, making them suitable for studying cerebral blood flow and cerebrospinal fluid (CSF) dynamics. In a 7‐T study of 13 participants performing a visual task, we demonstrate that UTE produced robust, reproducible activations with group‐level ...

Agricultural and Forest Entomology, Volume 28, Issue 3, Page 382-397, August 2026.We assess the effect of sanitation felling performed in 2022 in North‐Eastern Italy on bark beetle damage that occurred in 2023 across eight spruce forest types, as evaluated using multispectral satellite imagery. Bark beetle damage was reduced only at very high or very low sanitation felling rates.

Some Comparisons Between FIR and IIR Digital Filters
, 1977 Some comparisons are made between optimum, linear phase, finite impulse response (FIR) digital filters and infinite impulse response (IIR) digital filters which meet equivalent frequency domain specifications.

New classes of frequency-response masking FIR filters
, 2000 This paper introduces new classes of frequency-response masking (FRM) FIR filters. In the FRM approach, the overall filter makes use of periodic model filters and nonperiodic masking filters which makes it possible to obtain FIR filters requiring few ...

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.Capsules in the forest: using unmanned aerial vehicle deployment, we tested pelleted capsules and engineered pods in greenhouse and field trials. Pods improved early field establishment compared with pelleted capsules, while predation remained a major limit to final survival.

Design of linear phase FIR filters using fractional derivative constraints
, 2014 [[abstract]]In this paper, the designs of linear phase FIR filters using fractional derivative constraints are investigated. First, the definition of fractional derivative is reviewed briefly. Then, the linear phase FIR filters are designed by minimizing

CNS Neuroscience &Therapeutics, Volume 32, Issue 7, July 2026.(A) Fifty MDD patients underwent an 8‐week TECAS treatment and were then classified into responders and nonresponders according to their clinical outcomes. (B) Resting‐state EEG was acquired from all participants and subsequently preprocessed. (C) Functional connectivity analysis revealed that TECAS modulates frontoparietal θ‐band connectivity in MDD ...

Design of efficient FIR filters with minimal delay
, 1986 A new design method for approximately linear phase narrow-band lowpass and highpass FIR filters is presented. Also an efficient filter structure is introduced for realising the designed filters.

Scalable Reverse Converters for the Moduli Set {2n+1−1,2n−1,2n−1−1} ( n Even)
International Journal of Circuit Theory and Applications, Volume 54, Issue 7, Page 3865-3871, July 2026.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 ...
