A New Strategy to Design Reconfigurable Rivest–Shamir–Adleman (RSA) Accelerators

International Journal of Circuit Theory and Applications, EarlyView.
A reconfigurable FPGA‐based RSA accelerator is proposed using compression‐based modular multipliers combined with pseudomoduli arithmetic. The approach maps modular exponentiation to low‐cost arithmetic domains and applies a correction stage, achieving significant improvements in delay, operating frequency, and delay–area efficiency compared with ...

Nonsilting transport characteristics of coal slurry in a deep underground fluidization conveying pipeline under the action of a guide vane swirler

Deep Underground Science and Engineering, EarlyView.
Aiming at the scientific frontiers of in situ fluidized mining of deep resources, a deep coal fluidized pipeline lifting system based on hydraulic conveying has been proposed. To solve the issue of particle sedimentation of large particles in horizontal connection sections, a solution involving the installation of guide vane‐type swirlers in the ...

Mass Exchange Flow Process in Side Channel Pumps: Effects of Different Geometrical Parameters

Energy Science &Engineering, EarlyView.
Figure 1 shows the Mass Flow Exchange (MFE) in the impeller at z = 7.5 × 10−3 m at 1.0 Q/QBEP, operating point for impeller scheme 1 (IMP 1), and impeller scheme 2 (IMP 2). The flow begins to exit the impeller at the outer radius and enters at the inner and central radii. IMP 1 exhibits more flow in and out compared to IMP 2. ABSTRACT The functionality

Robust Control Using a Matrix Converter to Enhance Wind Turbine Systems

Energy 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.

Efficient Numerical Framework for Geothermal Energy Production Optimization in Fracture‐Controlled Reservoirs

International Journal for Numerical Methods in Fluids, EarlyView.
We introduce an efficient open‐source numerical framework for the automated search for the placements of injection and production wells in hot fracture‐controlled reservoirs that sustainably optimize geothermal energy production. We model the reservoirs as discrete fracture networks in 3D. The fluid flow and heat transport in the reservoirs are modeled

Mapping Alkyne Chemical Space—Classifying the Reactivity of Alkynes in Semihydrogenation and beyond Using a Data Science Framework

Helvetica Chimica Acta, EarlyView.
A data science framework integrating DFT featurization and hierarchical clustering was used to map the chemical space of over 2700 alkynes into six subsets before using experimental data for Ni3Zn‐catalyzed semihydrogenation and applying a logistic regression model to categorize substrates by reactivity.

Taking Pride in Vegan Consumption: A Construal Level Theory Account of Ad Message Appeal and Future Self Connectedness

Psychology &Marketing, EarlyView.
ABSTRACT Despite growing interest in vegan products, research examining the motivations, underlying psychological processes, and boundary conditions that drive consumer preference for vegan products remains limited. Drawing on theories of temporal self and appraisal theory, we find that an immediate message appeal (e.g., animal welfare), as compared to
