Trajectories and drivers of compositional and functional variation in sagebrush steppe restoration
Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.Restoration success is often challenged by unpredictable and undesirable outcomes, especially in arid systems like the sagebrush steppe. In an 11‐year study in Grand Teton National Park, climatic conditions during establishment and local soil texture drove long‐term differences in plant community composition and functional traits.

Experimental Demonstration of Quantum Low Probability of Intercept for Ultra-Secure Communication
, 2023 Secure communication systems utilize encryption with shared keys between the sender and receiver of the encrypted message. For added security, the encrypted message can be hidden within a significant amount of noise so that the eavesdropper could not ...

Land Use Influences on Freshwater Biodiversity
Global Ecology and Biogeography, Volume 35, Issue 4, April 2026.ABSTRACT Aim Land‐use change is a major driver of biodiversity loss, but most generalisations about its effects come from terrestrial ecosystems. Given the fundamental differences in spatial structure and community assembly processes between terrestrial and freshwater ecosystems, biodiversity responses to land‐use change may diverge.

Usage of Costas arrays in Low Probability of Intercept radars
, 2015 Low Probability of Intercept (LPI) radars are used to detect targets at low distances by means of coded signals without being intercepted by hostile elements. Frequency Shift Keying (FSK) is one of the signal types used by LPI radars.
