Beyond species diversity: Functional responses of cave arthropods to microclimatic stability and structural complexity

Ecological Entomology, EarlyView.
Species richness declined along cave microclimatic gradient, while diversity increased with habitat heterogeneity, highlighting distinct roles of abiotic conditions and structural complexity in shaping arthropod communities. Functional traits shifted along the microclimatic gradient, with larger‐bodied and more eye‐regressed arthropods dominating under

Tunable ultrafast nonlinear optofluidic coupler

EPJ Web of Conferences, 2013
We present an ultrafast nonlinear coupler fabricated by selectively filling of two strands of a PCF with the liquid CCl4 which exhibits a large Kerr nonlinearity. We demonstrate power dependent switching in this optofluidic device.

Highly non-Gaussian states created via cross-Kerr nonlinearity

, 2007
We propose a feasible scheme for generation of strongly non-Gaussian states using the cross-Kerr nonlinearity. The resultant states are highly non-classical states of electromagnetic field and exhibit negativity of their Wigner function, sub-Poissonian ...

The Forgotten Pink Salmon in the Laurentian Great Lakes: An Unexpected Invasion With Insights for Three Oceans

Fish and Fisheries, EarlyView.
ABSTRACT Introductions of species outside their native range, such as pink salmon (Oncorhynchus gorbuscha) in the Laurentian Great Lakes, can serve as unplanned experiments that provide new insights into ecological adaptation. We synthesize available information on the understudied Great Lakes pink salmon invasion and highlight how this case can inform

Deterministic Generation of Entangled Photons in Superconducting Resonator Arrays

, 2011
We present a scheme for the deterministic generation of entangled photon pairs in a superconducting resonator array. The resonators form a Jaynes-Cummings lattice via the coupling to superconducting qubits, and the Kerr-like nonlinearity arises due to ...

Extremism at the center: Uncovering political diversity among midpoint responders on the left–right self‐placement item

Political Psychology, EarlyView.
Abstract The midpoint of the left‐right self‐placement item is hiding important political diversity, and may be conflating moderate responders with populists and other political sub‐groups. Survey researchers should consider this problem when examining relationships between political orientation and political attitudes.

Multi‐Metric Monitoring: Comparing Occupancy and Abundance Based Metric Sensitivity for Detecting Threatened Species Responses to Environmental Change

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Abundance and occupancy provide complementary but non‐equivalent signals of threatened species change. Here, their relationship was nonlinear and responses to environmental change were context dependent, showing that no single metric captures all population responses and that combining both can better inform conservation action under global change ...

Asymmetrical temporal dynamics of edge modes in Su-Schrieffer-Heeger lattice with Kerr nonlinearity

Physical Review Research
Optical bistability and oscillating phases exist in a Sagnac interferometer and a single ring resonator made of a χ^{(3)} nonlinear medium where the refractive indices are modulated by the light intensity due to the Kerr nonlinearity. An array of coupled

Resolving the Internal Magnetic Domain Structure of Cloudy Zone Tetrataenite

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Recent advances in magnetic imaging can directly capture the internal magnetization of natural and synthetic materials at resolutions <10 nm. This capability opens new possibilities to determine the magnetic domain state of ferromagnetic minerals that are fundamental for recording and retaining paleomagnetic records.
