Transponder Designs for Harmonic Radar Applications [PDF]

, 2015
This work presents a review on the concept of harmonic or secondary radar, where a tag or transponder is used to respond at a harmonic multiple of the incoming interrogation signal.

A hybrid active filter for damping of harmonic resonance in industrial power systems [PDF]

, 1998
This paper proposes a hybrid active filter for damping of harmonic resonance in industrial power systems. The hybrid filter consists of a small-rated active filter and a 5th tuned passive filter.

Effect of age class on the survivorship and spatial movement patterns of headstarted Texas horned lizards soft‐released into an urban population

The Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
When compared to resident lizards of the corresponding age class, juvenile headstarted Texas horned lizards soft‐released into an urban population exhibited more favorable responses to short‐term translocation objectives (i.e., daily movement rates, home range sizes, and survival rates) than did conspecifics headstarted to the adult age class ...

Evaluating the efficacy of tagging adhesives for insect tracking

Agricultural and Forest Entomology, Volume 28, Issue 3, Page 515-521, August 2026.
Two‐part epoxy resin delivered the strongest RFID tag adhesion on carabid beetles, exceeding polyvinyl acetate, cosmetic latex and cyanoacrylate adhesives. Adhesive performance was consistent across Harpalus, Leistus and Poecilus; species effects were non‐significant, supporting a broadly applicable protocol for carabid RFID tagging studies.

Validating gut flushing as a non‐lethal sampling technique for diet monitoring in agastric fish

Journal of Fish Biology, Volume 108, Issue 4, Page 1192-1199, April 2026.
Abstract Non‐lethal diet sampling is essential where individual‐level monitoring and welfare matter, yet evidence on season‐long outcomes in agastric fishes is scarce. We tested syringe‐based gut flushing in pond‐reared common carp Cyprinus carpio over one growing season (April–September) using PIT‐tagged fish assigned a priori to three handling ...

Nanopower CMOS transponders for UHF and microwave RFID systems [PDF]

, 2007
At first, we present an analysis and a discussion of the design options and tradeoffs for a passive microwave transponder. We derive a set of criteria for the optimization of the voltage multiplier, the power matching network and the backscatter ...

Selection Against Hybrids Maintains Genetic Divergence Between Populations of a Coastal Cleaner Fish Translocated Across a Genetic Break

Evolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT Genetic divergence between populations and/or species is mainly driven by reproductive isolation, that is, reduced gene flow, due to either pre‐ and/or postzygotic barriers. In this study, we investigate the role of (i) reproductive ecological interactions and (ii) mechanisms of evolutionary isolation between two genetically differentiated ...
