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.

Profile analysis with reconstruction robustness for measurement data subject to outliers [PDF]

, 2022
In the surface profile analysis, there are often a few observations that contain outliers. Due to the existence of outliers, the application of non-robust reconstruction algorithms for measurement data will become a huge problem because these methods are

A WTLS-based rational function model for orthorectification of remote-sensing imagery [PDF]

, 2017
The rational function model (RFM) is widely applied to orthorectification of aerial and satellite imagery. This article proposes a new method named Ortho-WTLS to solve the RFM in remote-sensing imagery orthorectification.

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.
