ALERA‐V Version 1.0: An Objective Analysis Dataset of the Venus Atmosphere

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
Using observations from the Venus orbiter Akatsuki, we present the first objective analysis dataset of the Venus atmosphere. ALERA‐V, generated with the ALEDAS‐V system using the LETKF, is expected to support studies of atmospheric dynamics and the planning of future satellite missions.

A Field-Theoretic Gravitodynamic Framework Consistent with General Relativity

Reports in Advances of Physical Sciences
We present a covariant field-theoretical model of gravitation based on a structural analogy with classical electrodynamics. The theory employs a four-potential formulation and introduces dynamic gravitational fields, including a gravitomagnetic component

The Concept of Revolution in the Sciences: Michael Polanyi's Differences With Thomas Kuhn on Scientific Revolutions

Natural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT Thomas Kuhn's The Structure of Scientific Revolutions (1962) was a blockbuster publication that problematized notions about the origins and nature of scientific revolutions. What became Kuhn's famous rubrics of “normal science” and “paradigms” were similar to concepts of “tacit knowledge” and scientific “frameworks” or “dogmas” in Michael ...

Spheres, tears, and spears: Regulating the perimeter and circularity of millimeter‐sized alginate hydrogel beads

AIChE Journal, Volume 72, Issue 6, June 2026.
Abstract Generating hydrogel beads pertains to many engineering applications. We examined two alginate‐based fluids at three concentrations of alginate, cAG. We used the “Map of Misery” to determine which material property (viscosity, elasticity, and inertia) drives droplet formation. Next, we measured the perimeter and circularity of hydrogel beads as

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

International Journal for Numerical Methods in Fluids, Volume 98, Issue 6, Page 709-730, June 2026.
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

A Novel Test for MOND: Gravitational Lensing by Disk Galaxies

The Astrophysical Journal
Disk galaxies represent a promising laboratory for the study of gravitational physics, including alternatives to dark matter (DM), owing to the possibility of coupling rotation curves’ dynamical data with strong gravitational lensing (SGL) observations ...

Teaching-oriented modeling and numerical demonstration of Newton's law of gravitation

Frontiers in Applied Mathematics and Statistics
Based on Newton's laws of motion and Kepler's empirical laws, this study presents a pedagogically oriented derivation of the inverse-square law of gravitation and develops a numerical model to simulate two-dimensional planetary motion under central ...

CFD Analysis of Dual‐Layer PCM Roofs for Thermal Mitigation in Residential Buildings

Heat Transfer, Volume 55, Issue 4, Page 2290-2312, June 2026.
ABSTRACT This study presents a computational fluid dynamics analysis of dual‐layer phase change material (PCM) roofs for passive cooling in residential buildings under the hot and humid climate of Bangladesh. A three‐dimensional transient model was developed in ANSYS Fluent using the enthalpy–porosity approach to simulate coupled heat conduction ...

Three Methods for Combining Probability Distributions and an Alternative to Random-Effects Meta-Analysis

Metrology
Many fields or disciplines (e.g., uncertainty analysis in measurement science) require a combination of probability distributions. This technical note examines three methods for combining probability distributions: weighted linear pooling, geometric ...
