Integrating Machine Learning and StoDyM for Check Dam Site Selection on the Loess Plateau, China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Severe soil erosion in the Loess Plateau has led to significant land degradation, threatening agricultural productivity and ecosystem stability. Check dams, as a critical soil–water conservation measure, have proven effective in mitigating sediment loss and reclaiming farmland.

Stakeholder-led science: engaging resource managers to identify science needs for long-term management of floodplain conservation lands

open access: yesEcology and Society, 2016
Floodplains pose challenges to managers of conservation lands because of constantly changing interactions with their rivers. Although scientific knowledge and understanding of the dynamics and drivers of river-floodplain systems can provide guidance to ...

Modelling profit series: nonstationarity and long memory [PDF]

open access: yesApplied Economics, 2008
The dynamic structure of profit rates for 156 US manufacturing companies is analyzed by means of fractional integration techniques as an alternative to the commonly used ARIMA models with respect to the ''persistence of profits''. Thereby the pseudo spectral density aproach of Velasco and Robinson together with model selection criteria is applied.

Asymmetric Responses of Ecosystem Health to Urbanization in a Typical Karst City: Spatiotemporal Patterns and Driving Mechanisms in Guilin, China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Urban expansion can substantially reshape ecosystem structure and functioning, especially in ecologically fragile Karst landscapes. Clarifying how ecosystem health (EH) responds to urbanization and identifying the factors that drive spatial variation in EH are important for regional sustainability.

Artificial Intelligence, Economic Decision‐Making, and Air Transport Performance: Evidence From G7 Countries

open access: yesManagerial and Decision Economics, EarlyView.
ABSTRACT This paper examines the role of artificial intelligence (AI) in shaping economic decision‐making and improving air transport performance in G7 countries over the period 1996–2021. AI is proxied by scientific publications and interpreted as an indicator of innovation capacity that supports data‐driven decision‐making and operational efficiency ...

Nonstationarity in wildlife disease dynamics: insights from the prairie dog–plague system

open access: yesOikos, EarlyView.
Ecological relationships often vary in strength and direction across ecosystems, a pattern that has become increasingly evident as ecology expands to broader spatial and temporal scales. Although such nonstationarity – the changing effect of predictor variables across spatiotemporal contexts – is widely acknowledged in ecological research, it has ...

Using dendroclimatic analysis of exotic deciduous conifers in an arboretum to document tree growth in response to climate change, Northeast Ohio, USA

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Rising temperatures and wetter conditions in the Midcontinent of North America are influencing climate responses in trees. Dendroclimatological analyses of four exotic deciduous conifer species from Secrest Arboretum, Northeast Ohio help identify past, present and future climate‐tree interactions.

Reconstructing Long‐Term Historical Hydrologic Alteration to Support Environmental Flows in Texas

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Understanding and quantifying hydrologic alteration is essential for effective watershed management and ecological conservation. This study developed a modeling framework to predict reference hydrology and assess and model hydrologic alteration across Texas using publicly available geospatial datasets.

A Nonstationary Stochastic Rainfall Generator Conditioned on Global Climate Models for Design Flood Analyses in the Mississippi and Other Large River Basins

open access: yesWater Resources Research
Existing stochastic rainfall generators (SRGs) are typically limited to relatively small domains due to spatial stationarity assumptions, hindering their usefulness for flood studies in large basins.

Selective Gas Detection by a Single MOX-Sensor

open access: yesProceedings, 2017
Selective analysis of CO gas, hydrogen and hydrogen sulfide was carried out using single metal oxide sensor. Non-stationary sensor heating mode allowed discovering individual peculiarities of each gas in question. Resistance vs.
