Magnetic 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 ...

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.Abstract Understanding vegetation's response to soil water availability and atmospheric demand is critical for assessing the impact of drought and climate change on semi‐arid ecosystems. However, limited field‐based research has been conducted to assess the relative importance of these drivers on vegetation productivity.

Design Of Polar-Separable Fir Filters By Radial Slice Approximations
, 1997 We introduce the design of polar-separable 2-D FIR filters by radial slice approximations (RSA). It is a two step procedure. First, 1-D filters for the radial and the angular components are designed.

Journal of Animal Ecology, Volume 95, Issue 7, Page 1220-1234, July 2026.Anthropogenic disturbances associated with mineral extraction influenced space use and activity patterns in grizzly bears, and to a much lesser extent in black bears, in a subarctic ecosystem, signalling an asymmetric response. Abstract Niche partitioning is an evolutionary process that allows the coexistence of multiple species in a landscape. However,

Design and implementation FIR filters using FPGA
, 2008 Underwater acoustic channels are characterized by multipath phenomenon whose characteristics are time varying. Multipath propagation contributes to signal fading, and causes intersymbol interference (ISI) in a digital communication system.

Designing lowpass fir filters with a prescribed group delay
, 1988 A computer program is implemented which designs lowpass FIR filters with a prescribed group delay in the passband. This involves converting a complex-valued approximation into a nearly equivalent real approximation. A linear programming algorithm is then

Entomological Research, Volume 56, Issue 7, July 2026.ABSTRACT Subalpine conifers such as Abies koreana E.H.Wilson (Korean fir) play a significant ecological role but are increasingly endangered due to the effects of climate change, including the high prevalence of insect pests. This study identified for the first time, a notorious aphid pest on newly developed needles and twigs of A.

Design of Acoustic Equalization Filters for Headphones Based on Low-Rank Regularization
IEEE Open Journal of Signal ProcessingThe use of equalization filters to achieve acoustic transparency can improve the sound quality of hearables and hearing aids. Finite impulse response (FIR) filters guarantee stability and offer a listening impression close to the open ear, but their ...

Freshwater Biology, Volume 71, Issue 7, July 2026.ABSTRACT Fishless lakes, which may harbour higher biodiversity than lakes with fish, are becoming increasingly rare due to fish introductions. Although the impacts of fish introduction are relatively well studied in high‐elevation fishless lakes, previous studies have mainly focused on a single invertebrate community or on a particular life stage of a ...
