Multiple injection techniques to stimulate complex fracture networks in coal reservoirs: A case study on gas disaster reduction of subsurface coal mine in southwest China

Deep Underground Science and Engineering, EarlyView.
An experimental device for physical simulation of hydraulic fracturing, comprising: a load‐bearing mechanism with multiple interconnected plates that collectively form an sample chamber; a load‐generating mechanisms, with multiple load‐generating mechanisms arranged within the experimental chamber.

Precipitation and tree biomass correlate with the diversity and functional composition of tropical rainforest cricket assemblages across climate and disturbance gradients

Ecography, EarlyView.
Disturbance‐driven changes in rainforest structure and environmental conditions can alter ecosystem functioning, yet the consequences for invertebrate communities – key contributors to decomposition, herbivory, and trophic interactions – are not fully understood, particularly in relation to structural changes in vegetation.

Heave induced reduction of friction capacity of pile embedded in clays

MATEC Web of Conferences, 2017
Installation of new piles may cause heave which influence friction capacity of existing piles. The heave can be observed from the difference in the elevation of existing pile heads recorded before and after the installation of new piles or through load ...

Seismic Design of Concrete Dams: An Integrated Risk‐Informed Performance‐Based (RIPB) Framework

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper advances the integration of risk‐informed principles into the seismic design of dams—a domain long guided by standards‐based, largely deterministic approaches. While performance‐based earthquake engineering is well established for buildings and bridges, its systematic adoption in dam engineering remains limited. We first address two

Oil Futures Prices, Inflation Expectations, and Bond Risk Premiums

Journal of Futures Markets, EarlyView.
ABSTRACT By decomposing West Texas Intermediate futures price changes into structural supply and demand shocks, this paper shows that dissecting the oil price significantly improves inflation forecasts. Empirically, demand‐driven shocks predict a negative real bond risk premium but a positive inflation risk premium; these opposing effects result in an ...

Finite element modelling of the uplift behaviour of screw piles in sand [PDF]

, 2019
In this paper a simplified procedure to incorporate some installations effects into the numerical finite element modelling of screw pile uplift is presented. The procedure consists of the approximation of the installation phase through 1) the application

Climate Change Has Already Reshaped North American Forest Pest Dynamics: Insights From Multidecadal Process‐Based Modelling

Global Change Biology Communications, EarlyView.
Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.

Yield, Evapotranspiration, Production Functions, Crop Coefficients, Water Productivity and Soil‐Water Extraction of Three Watermelon Varieties

Irrigation and Drainage, EarlyView.
ABSTRACT While watermelon is an important commodity in the United States and worldwide, some of the fundamental watermelon productivity indices (crop evapotranspiration [ETc], transpiration [Tr], evaporation [E], ET‐yield production functions [ETYPF], basal crop coefficients [Kcb], crop water productivity [CWP], soil‐water extraction [SWE]) have not ...
