Monitoring semi‐aquatic mammals is essential for their conservation, but it is made difficult by their elusive lifestyle and generally low abundance. Eurasian otter (Lutra lutra) monitoring has traditionally relied on scat surveys, but eDNA and camera‐trapping are emerging as promising alternatives.

ABSTRACT Can sociologists feel? Sociological writing can be beautiful, making us think differently about people, processes, and structures. Yet traditional academic writing that does this is rare. For example, most articles adhere to a jargon‐filled format and structure that mimics a detached and disciplined writer.

Fractal Antennas (Study and Review)
In recent years, great demands for an antenna with many falsities like miniaturization, multiband and wideband antenna with high gain and low profile antenna for modern wireless communication services and applications. Fractal antenna paves the way for these requirements. In this survey, we will attempt to study and review the existing fractal antennas

Is the World Getting Smaller? Network‐Driven Heterogeneity in Gravity‐Model Elasticities
ABSTRACT Gravity models constitute the workhorse of empirical international trade research, yet the temporal stability of their core parameters—distance and GDP elasticities—remains underexplored, particularly in relation to the evolving structure of trade networks.

With wireless multifrequency applications, this research paper presents how to use genetic algorithms (GA) to design a hybrid fractal microstrip antenna based on the Minkowski and Sierpinski carpet fractal microstrip structures. The traditional design of

Abstract Plant biomass measurements are critical for crop improvement and breeding programs. Such measurements rely on destructive and labor‐intensive methods that limit continuous measurements of biomass over plant growth stages and time. This study aimed to develop an inexpensive, nondestructive method for estimating aboveground biomass in rice ...

Abstract Spatial heterogeneity, manifested as strong variability in hydraulic conductivity (K) within geological formations, exerts a fundamental control on groundwater flow and solute transport. Because K can vary over multiple orders of magnitude in complex three‐dimensional patterns, predicting contaminant plume migration remains a long‐standing ...
