ABSTRACT Urban resilience and ecosystem health are essential foundations for regional sustainable development, yet their coupled and coordinated relationships remain insufficiently explored at the urban‐agglomeration scale. Taking the 13 prefecture‐level cities in the Beijing‐Tianjin‐Hebei urban agglomeration as the study area and using panel data for ...

ABSTRACT Soil salinization negatively impacts the economic development and ecological environment, particularly in the arid and semiarid regions of China. The Qaidam Basin constitutes a major distribution area of saline‐alkali land in the country. However, the distribution patterns of salinity and nutrients within soil profiles and the underlying salt ...

A Three Valued Morse-Thue Fractal Tapering for Thinning of Fractal Array Antennas
Fractal array antennas are multiband and broadband array antennas having space filling capability. But large Side lobe levels and the huge number of elements are the prominent challenges in the designing of these arrays. In this paper, analysis of linear

Unripe banana flour is a starch source with a high content of resistant starch in its raw form. Recently, interest has grown in raw materials with low levels of indigestible carbohydrates. Different banana genotypes vary in granule morphology, which influences their functional properties and digestibility.

Towards Fractal Antennas: A multiband Sierpinski Triangle (Gasket) Fractal Vivaldi Antenna
Using Sierpinski Triangle Fractals (STFs), a revised Vivaldi antenna with multiband coverage is presented. This report explains how fractal itera-tions can be increased to increase the impedance bandwidth and create new bands for multiband applications.

Enabling and exploiting self-similar central symmetry formations [PDF]
In this work a formation flying based architecture is presented within the context of a distributed antenna array. An artificial potential function method is used to control the formation whereby deviation from an all-to-all interaction scheme and swarm ...
