Denoising method and application of microseismic signals for coal seam hydraulic fracturing based on deep neural network mode

Meitan xuebao
To address the challenges of low signal-to-noise ratio and difficulty in phase picking of microseismic signals induced by coal fracturing during hydraulic fracturing in coal seams, a deep neural network model based on a masking strategy is proposed (Mask

An Autonomous Large Language Model‐Agent Framework for Transparent and Local Time Series Forecasting

Advanced Intelligent Discovery, EarlyView.
Architecture of the proposed large language model (LLM)‐based agent framework for autonomous time series forecasting in thermal power generation systems. The framework operates through a vertical pipeline initiated by natural language queries from users, which are processed by the LLM Agent Core powered by Llama.cpp and a ReAct loop with persistent ...

Satyagraha on Natal's Coal Mines

Journal of Natal and Zulu History, 2013
The Satyagraha campaign of 1913 was the first mass protest by Indians in South Africa. Well over 20,000 men, women and children participated in the struggle against discriminatory measures. Defiance took several forms: individual acts of hawking without a licence, defying immigration laws, and protests on the coal mines.

Cognitive Performance in Young Adults During Three Consecutive Days of Simulated Occupational Heat Stress: An Exploratory Study

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Global increases in occupational heat exposure are raising concerns about worker safety and cognitive performance during prolonged and repeated shifts. At present, the cumulative effects of repeated heat exposure on cognitive performance remain unclear.

Effect of Laser Posterior Nasal Neurolysis for the Treatment of Chronic Rhinitis: A Randomized Controlled Trial

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background To determine the safety and efficacy of laser ablation of the posterior nasal nerve (PNN) for the treatment of chronic rhinitis. Methods This study was a single‐center, prospective, single‐blinded, randomized sham‐controlled trial. Patients with a 24‐h reflective Total Nasal Symptom Score (rTNSS) ≧ 5, rhinorrhea ≧ 2, and congestion ≧

Study on evolution characteristics of fracture field in hard thick overlying strata based on geological generalization

Meikuang Anquan
Accurately grasping the evolution characteristics of the water-conducting fracture zone in the mining overburden is an important basis for preventing the occurrence of water inrush disasters in the working face, especially for the high strength mining ...

CO‐Adsorption on MgO Revisited: Polarization‐Resolved Identification of Step Edges as the Dominant Defects on MgO(100) and MgO(110)

Angewandte Chemie International Edition, EarlyView.
By combining polarization‐resolved IRRAS with hybrid HSE06 DFT calculations, we establish site‐specific vibrational fingerprints, adsorption geometries, and binding energies for CO on wide‐band‐gap MgO surfaces. Low‐coordinated Mg4c2+ step‐edge sites, rather than terrace Schottky defects, are identified as the dominant binding and reactive sites, with ...

Image-based quantitative probing of 3D heterogeneous pore structure in CBM reservoir and permeability estimation with pore network modeling

International Journal of Coal Science & Technology
Coalbed methane (CBM) recovery is attracting global attention due to its huge reserve and low carbon burning benefits for the environment. Fully understanding the complex structure of coal and its transport properties is crucial for CBM development. This

Advancements in CO2 Capture Technologies: A Review of Amine Absorption and Alternative Methods for Post‐Combustion Integration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.

Design and Optimization of a Double‐Column Vapor Recompression Heat Pump Distillation Process via NSGA‐II for Separating Ternary Wide‐Boiling Mixtures

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study proposes a novel double‐column vapor recompression heat pump (DCVRHP) distillation process for separating ternary wide‐boiling‐range mixtures under two different vapor conditions: n‐hexane/n‐heptane/n‐octane using low pressure steam and n‐hexanol/n‐octanol/n‐decanol using high pressure steam.
