Thermodynamic study of bulk and surface properties of Pb − Tl and In − Tl liquid alloys

Abstract In this study, the bulk and surface properties of Pb $$-$$ Tl and In $$-$$ Tl liquid alloys are investigated at 773 K and 723 K, respectively. Because these properties are difficult and expensive to determine experimentally at high temperatures, theoretical models are employed. For each alloy, the self-associa...

DiffINR: conditional neural field diffusion for deformation-driven volumetric image estimation from limited measurements

Objective. We propose DiffINR for rapid deformation-driven estimation of patient-specific target volumes from limited measurements. DiffINR uses a coordinate-based implicit neural representation (INR) to estimate a dense deformation vector field (DVF) that warps a high-quality prior volume (source) to the target anatom...

Convergence in Asia This Century

Asia is entering a century defined by a powerful interaction between economic growth, technological diffusion, human‑development gains and rising adaptive capacity. The report argues that convergence is no longer a simple GDP catch‑up story but a reinforcing development system in which capital accumulation, innovation,...

From the “death of distance” to digitalisation traps: a general purpose technology perspective on peripheral regions

Abstract Digitalisation is widely viewed as an enabler of sustainable development and regional convergence, yet substantial spatial disparities in uptake persist. This paper develops a general-purpose technology (GPT) perspective on peripheral regions, arguing that because digital technologies rely on complementary ass...

Coupled AD–Hankel WFLO: A Reproducible Python Framework for Wind-Farm Layout Optimisation Using a Semi-Analytical Actuator-Disk Wake Model

Overview Coupled AD–Hankel WFLO is a Python research-software and numerical-reproducibility package developed to support physics-informed wind-farm layout optimisation (WFLO). The framework integrates a two-dimensional, load-resolved, semi-analytical actuator-disk model with a momentum-constrained far-wake continuation...

Diffusivity of Potato and Apple

Drying is a classic example of heat and mass transfer and is a very important method for food preservation. In this case, diffusivity is an important parameter in mass transfer. Although we distinguish between different internal transfer mechanisms, such as: pure diffusion, surface diffusion, Knudsen diffusion, capilla...

Brownian Motion as Deterministic Arithmetic Friction and the Death of the Wiener Process

We present the computational and theoretical framework for extending the Computational Finitism paradigm to statistical mechanics and diffusion. Standard physics models Brownian motion via the Langevin equation and the Wiener process, relying on two foundational fallacies: the continuum assumption (infinitesimal time a...

Fiber-Scale Discrete Element Modeling Approach for Microstructural Evolution in Carbon Felt Electrode Manufacturing

Porous carbon components strongly influence transport, kinetics, and performance in electrochemical energy devices, like electrodes in redox flow batteries or gas diffusion layers in proton exchange membrane fuel cells. Yet quantitative links between industrial felt manufacturing and the resulting microstructure remain...
