Introducing Technical Indicators to Electricity Price Forecasting: A Feature Engineering Study for Linear, Ensemble, and Deep Machine Learning Models

open access: yesApplied Sciences, 2019
Day-ahead electricity market (DAM) volatility and price forecast errors have grown in recent years. Changing market conditions, epitomised by increasing renewable energy production and rising intraday market trading, have spurred this growth. If forecast

The Larger the Egg, the Safer the Nest: A Study on the Negative Correlation Between Nest Predation Rates and Egg Size of Two Tropical Phasianids in Hainan

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
There is a lack of research on the predation of tropical pheasant nests. The study conducted artificial nest experiments based on egg size and we have supported the viewpoint that using experimental eggs matched in size with those of natural eggs improves the accuracy of artificial nest simulation studies. ABSTRACT Nest predation is the principal cause

Smart Meter Error Estimation in Topological Low Voltage Energy System

open access: yesIEEE Access
Smart meter is a key component in the energy grid. In order to detect the abnormal smart meter in a topological low voltage energy system, the orthogonal matching pursuit and Bollinger Band followed by the recursive model are proposed in this paper.

Carbon and water dynamics of Old World bluestem in the U.S. Southern Great Plains

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Forage production in the Southern Great Plains of the United States relies heavily on Old World bluestem (OWB, Bothriochloa spp.). This study analyzed 4 years (2021–2024) of continuous eddy covariance measurements in a managed OWB pasture in central Oklahoma, spanning both drought and wet periods.

Coseismic surface deformation from air photos: The Kickapoo step over in the 1992 Landers rupture [PDF]

open access: yes, 2006
Coseismic deformation of the ground can be measured from aerial views taken before and after an earthquake. We chose the area of the Kickapoo-Landers step over along the 1992 Landers earthquake zone, using air photos (scale 1:40,000) scanned at 0.4 m ...

Trading Strategies on Local Electricity Markets Using Agent‐Based Modelling and Reinforcement Learning: Vectors to Expand Energy Communities

open access: yesSystems Research and Behavioral Science, Volume 43, Issue 3, Page 1188-1211, May/June 2026.
ABSTRACT Energy communities (ECs) members have a high degree of heterogeneity. Agent‐based modelling (ABM) allows for the modelling of each entity as an agent with distinct characteristics and decision rules. This is particularly useful when the heterogeneity of agents affects outcomes.

Using Affirmative Action as a Tiebreaker

open access: yesJournal of Applied Philosophy, Volume 43, Issue 2, Page 372-388, May 2026.
ABSTRACT We argue in favor of affirmative action. There are two central points to our argument. First, if two or more candidates for a position are matched in competence, then one ought to prefer a candidate from a disadvantaged, disenfranchised, or minority background rather than defer to the outcome of a lottery.

Effects of Whole‐Body Vibration on Lower‐Limb Muscle Activity in a Flywheel Half‐Squat

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 4, April 2026.
ABSTRACT Strength and conditioning professionals continuously seek innovative strategies to enhance neuromuscular performance. This study examined muscle activation in the rectus femoris (RF), vastus lateralis (VL), vastus medialis (VM), biceps femoris (BF), gluteus maximus (GMAX), gastrocnemius medialis (GASMED), and gastrocnemius lateralis (GASLAT ...
