Local and Tele‐Coupling Coordination Relationships Between Urban Resilience and Ecosystem Health in the Beijing‐Tianjin‐Hebei Region and Analysis of Their Influencing Factors

open access: yesLand Degradation &Development, Volume 37, Issue 16, Page 11697-11718, October 2026.
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 ...

A Study on the Distribution Characteristics of Salinity and Nutrients and the Migration Mechanism of Soil Salt in the Delingha Saline‐Alkali Soil Profile of the Qaidam Basin

open access: yesLand Degradation &Development, Volume 37, Issue 16, Page 11867-11884, October 2026.
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

open access: yes, 2016
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 Genotypes are Starchy Sources. Part I. Morphology, Growth Rings, and Ultrastructure of Native Starches

open access: yesStarch - Stärke, Volume 78, Issue 10, October 2026.
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

open access: yes, 2023
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.

Recruitment Agents in a Debt‐Financed Migration Regime: Moving Domestic Workers From Indonesia to Singapore

open access: yesGlobal Networks, Volume 26, Issue 4, October 2026.
ABSTRACT In ‘fly now, pay later’ systems across Southeast Asia, migrant domestic workers accrue a snowballing debt, through recruitment processes beginning in their source villages and ending in their employers’ homes, which they repay through salary deductions.

Enabling and exploiting self-similar central symmetry formations [PDF]

open access: yes, 2014
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 ...

Fluctuating asymmetry based on fractal geometry does not track environmental stress in an intertidal habitat‐forming fucoid

open access: yesJournal of Phycology, Volume 62, Issue 5, Page 1597-1605, October 2026.
Abstract The availability of easy‐to‐measure and inexpensive biomarkers is a challenge for monitoring environmental stress in organisms. Although it has been proposed that non‐directional deviations from a symmetrical pattern in morphological traits (called fluctuating asymmetry.
