Emergent Scaling of Dissolved Oxygen (DO) in Freshwater Streams Across Contiguous USA

Water Resources Research, Volume 59, Issue 2, February 2023., 2023
Abstract Dissolved oxygen (DO) indicates the overall stream water quality and ecosystem health. We investigated emergent scaling of DO with the dominant environmental drivers in freshwater (non‐coastal) streams across the contiguous United States. Available data of monthly to quarterly sampling frequencies during 1998–2015 were obtained for 86 U.S ...

Uniformly Positive Correlations in the Dimer Model and Macroscopic Interacting Self‐Avoiding Walk in ℤd, d ≥ 3

Communications on Pure and Applied Mathematics, Volume 75, Issue 6, Page 1183-1236, June 2022., 2022
Abstract Our first main result is that correlations between monomers in the dimer model in do not decay to 0 when . This is the first rigorous result about correlations in the dimer model in dimensions greater than 2 and shows that the model behaves drastically differently than in two dimensions, in which case it is integrable and correlations are ...

Food web structure and community composition: a comparison across space and time in the North Sea

Ecography, Volume 2022, Issue 2, February 2022., 2022
Ecological communities are constantly changing as a response to environmental and anthropogenic pressures. Yet, how changes in community composition influence the structure of food webs over time and space remains elusive. Using ecological network analysis, we assessed how food web structure changed across six distinct areas of the North Sea over a ...

Design and Research of Low‐Cost and Self‐Adaptive Terrestrial Laser Scanning for Indoor Measurement Based on Adaptive Indoor Measurement Scanning Strategy and Structural Characteristics Point Cloud Segmentation

Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
Nowadays, TLS (terrestrial laser scanning) has been a relatively mature measuring equipment categorized to indoor measuring robots, but it is not widely adopted in indoor construction measurement at present. What accounts for its limited application are as follows: (1) the high cost of high‐accuracy laser LIDAR and (2) existing TLS equipment does not ...

Prediction and Explanation Models for Hot Metal Temperature, Silicon Concentration, and Cooling Capacity in Ironmaking Blast Furnaces

steel research international, Volume 92, Issue 9, September 2021., 2021
Herein, data‐driven prediction and explanation models for three process variables in ironmaking blast furnace processes are established. Fuzzy systems are used as interpretable model architecture with linguistically readable rules. Reliable prediction horizons of about 140 min for hot metal temperature and silicon concentration outperformance of ...

Accelerated vegetation succession but no hydrological change in a boreal fen during 20 years of recent climate change

Ecology and Evolution, Volume 11, Issue 12, Page 7602-7621, June 2021., 2021
We studied global change effects on vegetation and hydrology in a pristine boreal mire in a decadal time‐span. We repeated over 200 measurements of plant species cover, water‐table depth, and several water chemistry variables, after a marked shift to warmer conditions.

An iterative algorithm of NWTLS-EC for three dimensional-datum transformation with large rotation angle

Geodesy and Geodynamics, 2014
The Gauss-Markov (GM) model and the Errors-in-Variables (EIV) model are frequently used to perform 3D coordinate transformations in geodesy and engineering surveys.

Bearing-only target localization with uncertainties in observer position [PDF]

, 2010
In this paper, the bearing-only target localization problem when the observer positions are subject to error is investigated. In this problem, the angle of arrival of the transmitted signal between target and observer are used to estimate the target ...

Total least squares problems on infinite dimensional spaces [PDF]

, 2021
We study weighted total least squares problems on infinite dimensional spaces. We present some necessary and sufficient conditions for the regularized problem to have a solution.

How can we best use opportunities provided by routine maternity care to engage women in improving their diets and health?

Maternal &Child Nutrition, Volume 16, Issue 1, January 2020., 2020
Abstract Pregnancy provides motivation for women to improve their diets and increase their physical activity. Opportunistic brief interventions delivered as part of routine primary care have produced improvements in patients' health behaviour. Consequently, there have been calls for midwives to use contacts during pregnancy in this way.
