Supervised and Unsupervised Physical Activity Programs in Pregnancy—There Is a Benefit for Both

Journal of Diabetes Research, Volume 2026, Issue 1, 2026.
Objectives Regular physical activity (PA) during pregnancy reduces the risk of cardiometabolic disease. The World Health Organization recommends a minimum of 150 min/week of moderate‐intensity exercise for healthy pregnant women. However, these guidelines are not commonly met, and implications for pregnancy outcomes are not fully understood. This study

Modeling the Snow Depth Variability With a High‐Resolution Lidar Data Set and Nonlinear Terrain Dependency

Water Resources Research, Volume 55, Issue 11, Page 9689-9704, November 2019., 2019
Abstract In the mountains of Norway, snow depth (SD) is highly variable due to strong winds and open terrain. To investigate snow conditions on one of Europe's largest mountain plateaus, Hardangervidda, we conducted snow measurement campaigns in spring 2008 and 2009 using airborne lidar scanning at the approximate time of annual snow maximum (mid‐April)

Weighted multivariate curve resolution – alternating least squares based on sample relevance [PDF]

, 2023
Alternating least squares, within the multivariate curve resolution framework has seen a lot of practical applications and shows its distinction with its relatively simple and flexible implementation.

On weighted structured total least squares

, 2006
In this contribution we extend the result of (Markovsky et. al, SIAM J. of Matrix Anal. and Appl., 2005) to the case of weighted cost function. It is shown that the computational complexity of the proposed algorithm is preserved linear in the sample size

Substantial Mitigation Potential for Greenhouse Gases Under High Water Levels in a Cultivated Peatland in the Arctic

Global Change Biology, Volume 31, Issue 11, November 2025.
Elevating the water table in Arctic cultivated peatlands can substantially reduce greenhouse gas emissions, and even turn these systems into net GHG sinks. Fertilization enhanced biomass production but did not significantly affect CO2 or CH4 emissions, while biomass harvesting led to net carbon loss.

Robust Prediction Algorithm Based on a General EIV Model for Multiframe Transformation

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
In modern geodesy, there are cases in which the target frame is unique and there is more than one source frame. Helmert transformations, which are extensively used to solve transformation parameters, can be separately solved between the target frame and one of the source frames.

D‐NPC: Dynamic Neural Point Clouds for Non‐Rigid View Synthesis from Monocular Video

Computer Graphics Forum, Volume 44, Issue 2, May 2025.
Abstract Dynamic reconstruction and spatiotemporal novel‐view synthesis of non‐rigidly deforming scenes recently gained increased attention. While existing work achieves impressive quality and performance on multi‐view or teleporting camera setups, most methods fail to efficiently and faithfully recover motion and appearance from casual monocular ...

The element-wise weighted total least squares problem

, 2006
A new technique for parameter estimation is considered in a linear measurement error model AX approx B, A = A0 + tilde A, B = B0 + tilde B, with row-wise independent and non-identically distributed measurement errors tilde A, tilde B.

Orthogonal least squares regression with tunable kernels [PDF]

, 2005
A novel technique is proposed to construct sparse regression models based on the orthogonal least squares method with tunable kernels. The proposed technique tunes the centre vector and diagonal covariance matrix of individual regressor by incrementally ...

Biodegradability of dissolved organic carbon in boreal peatland forest is affected by water table, labile carbon, and nitrogen availability but not forest harvesting alone

Soil Science Society of America Journal, Volume 89, Issue 1, January/February 2025.
Abstract Around 30% of peatland in Nordic and Baltic countries has been drained for forestry. Drained peatlands are major sources of dissolved organic carbon (DOC) and nutrients to surface waters, contributing to global warming, eutrophication, and brownification.
