A co-optimization qubit mapping algorithm via two-stage search and bidirectional look

Abstract Current quantum devices typically lack full qubit connectivity, making it difficult to directly execute logical circuits on quantum devices. This limitation necessitates quantum circuit mapping algorithms to insert SWAP gates, dynamically remapping logical qubits to phys...

Managing hydraulic fracturing-induced seismicity in the Duvernay shale: Triggering mechanisms, influencing factors, and practice-oriented mitigation strategies

Abstract This review provides a Duvernay-focused synthesis of hydraulic fracturing (HF)-induced seismicity, integrating geological datasets, case studies of significant events, coupled poroelastic simulations, and machine-learning-based factor ranking. While the three underlying...

Silica Nanoparticle-Reinforced Wormlike Micellar Gels for High-Temperature Flow Redistribution in Heterogeneous Porous Media

Maintaining the rheological performance of wormlike micellar fluids at elevated temperatures remains challenging. Conventional viscoelastic surfactant (VES) systems may undergo thermally induced micellar scission and loss of gel-like viscoelasticity at elevated temperatures. In t...

A superelastic titanium alloy showing nearly temperature-independent high strength and elastic modulus

Lightweight superelastic alloys with temperature-insensitive properties are critical for deep-space exploration devices, yet their development is hindered by the challenge of simultaneously balancing strength, recoverable strain, and temperature sensitivity. Here, we overcome the...

A Mathematical Model for Predicting the Viscosity of Oil Emulsions as a Function of Water Cut

The formation of oil–water emulsions following reservoir-water breakthrough is widely observed during oil production. The viscosity of these polydisperse systems may increase sharply with increasing water cut, creating substantial operational difficulties in well-gathering system...

Deformation and Failure Mechanisms of Extra-Deep Carbonate Rocks Under In Situ Conditions: An Experimental Study

The exploration of oil and gas resources is shifting toward ultra-deep and extra-deep reservoirs, including in the Tarim Basin, where various types of carbonate rocks are buried. Owing to the extreme burial depths, the mechanical behavior of these rocks under extra-deep condition...

Hydrodynamic and mass transfer behaviors of NH 3 microbubbles in ionic liquids

Abstract Ionic liquids enable efficient ammonia‐containing gas separation, but conventional absorption towers suffer from limited interfacial area and mass transfer efficiency. Microchannels overcome this owing to their large specific surface area. This study investigated the hyd...

Numerical Investigation of Drilling Process for Complex Polar Ice Interlayers: An F-DEM Study

Subglacial drilling through polar ice–rock transitional zones is frequently hindered by severe load fluctuations and instability induced by strong formation heterogeneity. This study investigates the coupled drilling mechanics across pure ice, an ice–rock mixture, and bedrock usi...

Temporal Fusion Transformer for Fracture Evolution Prediction in Hot Dry Rock Hydraulic Fracturing

Hot dry rock (HDR) represents a highly promising sustainable clean energy resource for the future, with the fracture network induced by hydraulic fracturing serving as the cornerstone for thermal energy extraction efficiency. However, conventional numerical simulation tools are c...

Freeze–ThawCycles Greatly Affect the ConjugativeTransfer of Antibiotic-Resistant Genes: Effects of the Secretion ofExtracellular Polymeric Substances

Abstract Freeze–thaw (FT) cycle, a ubiquitous and important physical process in natural environments, may influence the horizontal gene transfer (HGT) process of antibiotic-resistant genes (ARGs), yet its impact and underlying mechanisms remain unclear. This study investigated th...

Infrastructure‐Constrained Pathways for Large‐Scale CO 2 Mitigation via CCUS in China's Coal‐Fired Power Sector

ABSTRACT Carbon capture, utilization, and storage (CCUS) is essential for decarbonizing coal‐dominated power systems, yet its large‐scale deployment in China is constrained by high costs, uneven storage resources, and limited transport infrastructure. This study develops a plant‐...

Crystallinity-Dependent Reverse Hydrogen Spillover Governs Electrochemical CO2 Reduction to Methane

Abstract The electrochemical CO2 reduction reaction (CO2RR) is a proton−electron coupled transfer process in which active hydrogen (*H) plays a pivotal role in determining the reaction pathways, particularly for methane (CH4), a representative deep hydrogenation product. However,...

Why Does AI Platform Competition Diverge? A Dynamic Analysis of Adoption, Recommendation Mechanisms, and Price Feedback

Generative AI and agentic systems are reshaping platform competition and its long-run welfare consequences. Existing research, however, does not explain why similar AI interventions can produce concentration, costly quality races, cyclical repricing, and different welfare outcome...

Control Mechanism of Water Shield on Pressure Dynamics of CO2 Huff-n-Puff and Crude Oil Mobilization Effect in Tight Reservoirs

Tight oil reservoirs are characterized by poor petrophysical properties, ultra-low permeability, and limited pressure-transmission capacity. After hydraulic fracturing, retained fracturing fluid can accumulate near the fracture–matrix interface and form a water shield, which rest...

Experimental Study of Methanol Leak and Diffusion in Open-Channel Flow

Methanol is highly soluble and with spreads quickly in natural water bodies, which could bring about serious environmental risks if leaked. In the present work, the transport and diffusion behavior of methanol in an open-channel flume under controlled hydraulic conditions is inve...
