Animal‐mediated seed dispersal: A review of study methods

Applications in Plant Sciences, Volume 14, Issue 1, January-February 2026.
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.

From Quarries to Urban Construction Sites: Middle‐Late Mesozoic Limestones in the Public Architecture of Roman Verona, Italy

Geoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Numerous buildings, monuments, and infrastructural works in Verona were constructed during the Roman period using stone, a material abundantly available from quarrying areas located relatively close to the city. Petrographic investigations conducted by Transmitted Polarized Light Optical Microscopy (TPL‐OM) and complemented by colorimetric ...

First Real‐Time Softwarization of Complete Coherent DSP Stack with Gardner Timing and Clock Recovery

Electronics Letters, Volume 62, Issue 1, January/December 2026.
ABSTRACT This work demonstrates the first fully softwarized coherent receiver digital signal processing stack implemented on a general‐purpose graphic processing unit (GPU) platform. By introducing a data‐parallel GPU implementation for Gardner‐based timing and clock recovery (TCR), the system achieves complete real‐time receiver operation without ...
