Similar Material Simulation Study on Dam Movement and Deformation Law of Deep Coal Seam Mining Under Dam

open access: yesEnergy Science &Engineering, EarlyView.
Aiming at the difficulties in accurately calculating the movement and deformation of small‐sized, deep‐buried dams with a significant height‐to‐depth ratio in deep fully mechanized caving mining, this study proposes to separate the analysis of surface and dam deformation.

Ensemble Deep Learning–Based Wind Power Forecasting With Self‐Adaptive Osprey Optimization Algorithm

open access: yesEnergy Science &Engineering, EarlyView.
Design of Self‐Adaptive Osprey (SAO) algorithm: The novel SAO algorithm is designed by integrating the exploration capability of the conventional Osprey algorithm by including the self‐adaptiveness for enhancing the convergence rate. Ensemble Deep Learning for wind power forecasting: The wind forecasting is employed using the proposed Ensemble learning

Robust Control Using a Matrix Converter to Enhance Wind Turbine Systems

open access: yesEnergy Science &Engineering, EarlyView.
This study uses a more efficient and effective solution to improve the operational performance of a wind turbine‐based power system. This system uses a doubly fed induction generator and relies on a matrix converter and fractional‐order proportional–integral controller.

Monitoring animal movement diversity as a component of biodiversity

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Animal movement is increasingly being quantified in novel ways, with high potential for integration into broad‐scale efforts to monitor biological diversity. Here, we define movement diversity as a form of biodiversity, measuring variation in animal movement from the level of individual animals to communities. We present a framework to develop a common

An Investigation of the Relationship Between Central Bank Unconventional Monetary Policy and Bitcoin Activity

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This article investigates whether the unconventional monetary policy (UMP) measures pursued by the Federal Reserve, the Bank of England, the Bank of Japan, and the European Central Bank since the Global Financial Crisis (GFC) are associated with an appetite for cryptocurrency.

Two Problems for the Political Inclusion of Animals

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT In recent years, the field of animal ethics has taken a political turn, with scholars arguing that sentient nonhuman animals should be included in the political sphere. This article explores two key challenges arising from this turn towards the political inclusion of animals: the Conflict Problem and the Numbers Problem.

Do ship strikes threaten the recovery of endangered eastern North Pacific blue whales

open access: yes, 2015
Blue whales were targeted in the North Pacific from 1905–1971 and are listed as endangered by the IUCN. Despite decades without whaling, abundance estimates for eastern North Pacific (ENP) blue whales (Balaenoptera musculus) suggest little evidence for a

Gastric antral vascular ectasia: A rare etiology of gastrointestinal bleeding in children

open access: yesJPGN Reports, EarlyView.
Abstract Gastrointestinal bleeding is relatively common in children. While most patients present with mild bleeding, gastric antral vascular ectasia (GAVE) is a rare but potentially life‐threatening cause. GAVE is typically associated with chronic conditions and more common in adults.

Determining the species assemblage and habitat use of cetaceans in the Svalbard Archipelago, based on observations from 2002 to 2014

open access: yesPolar Research, 2018
This study used 13 years of cetacean sighting data (2002–2014) from waters around the Svalbard Archipelago to determine key habitats for year-round resident species as well as seasonally resident species, and to explore spatial overlap between these ...
