Hacking the Colebrook-White equation: The Tolentino-𝒁 method via algebraic collapse and its bit-to-bit equivalence in 64-bit architectures [PDF]

INCAS Bulletin
The resolution of the Colebrook-White equation has historically been a stability challenge in Computational Fluid Dynamics (CFD) due to its transcendental and implicit nature.

On Asymptotic Relative Efficiencies of a Class of Rank Tests

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1970
Summary A partial ordering is introduced in a class of rank tests according to the weight or emphasis they place on the middle ranks versus the extreme ones. This notion of order is shown to be related to van Zwet's partial ordering of symmetric densities according to the probability in their tails. Bounds on Pitman's asymptotic relative

Photothermally Enhanced Hydrogel‐Based Thermoelectrochemical Cells for Stable, Passive Harvesting of Low‐Grade Heat

Advanced Energy Materials, EarlyView.
A photothermally enhanced hydrogel‐based thermoelectrochemical cell enables passive conversion of low‐grade heat and solar energy into electricity. The quasi‐solid device achieves high thermopower and stable long‐term operation under passive conditions.

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Delaying the Inevitable? U.S. Screwworm Closures and Feeder Cattle Market Dynamics

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Biosecurity trade restrictions are commonly framed as preventive measures, yet in many settings they function primarily as policies of delay: they impose immediate market costs while only postponing the arrival of biological risks. This paper evaluates that intertemporal tradeoff using the 2024–2025 US suspension of live cattle imports from ...

Consumer Preferences for Craft Beer: The Interplay of Localness and Advertising Language

Agribusiness, EarlyView.
ABSTRACT This study explores the influence of the language of the label, origin of production, and origin of brewing ingredients on Croatian consumers' preferences and willingness to pay for organic craft beer. Employing an online survey and a choice experiment among 223 Croatian alcohol consumers, we find that while there's a willingness to pay a ...
