The structure behind the Collatz algorithm

Ratio Mathematica
The Collatz algorithm gives the operations to apply to both even and odd numbers so that starting with any natural number and applying these operations repeatedly, the number one is eventually reached.

Advances in Modelling Radiative Transfer, Heat Storage and Turbulent Transport to Evaluate CO2, Heat and Water Fluxes Over Broad‐Leaved Forests: The CanVeg2 Model

Global Change Biology, Volume 32, Issue 4, April 2026.
The CanVeg2 biophysical model is presented with a focus on three novel components with regards to the CanVeg model: 3D ray tracing radiative transfer modeling, a stem energy budget, and wind and turbulence profiles from higher order closure modeling.

Detecting and attributing climate change effects on vegetation: Australia as a test case

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 461-485, March 2026.
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.

Register‐Based and Stack‐Based Virtual Machines: Which Perform Better in JIT Compilation Scenarios?

Software: Practice and Experience, Volume 55, Issue 11, Page 1896-1910, November 2025.
ABSTRACT Background Just‐In‐Time (JIT) compilation plays a critical role in optimizing the performance of modern virtual machines (VMs). While the architecture of VMs–register‐based or stack‐based–has long been a subject of debate, empirical analysis focusing on JIT compilation performance is relatively sparse. Objective In this study, we aim to answer

Parameter Estimation in Land Surface Models: Challenges and Opportunities With Data Assimilation and Machine Learning

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract Accurately predicting terrestrial ecosystem responses to climate change over long‐timescales is crucial for addressing global challenges. This relies on mechanistic modeling of ecosystem processes through land surface models (LSMs). Despite their importance, LSMs face significant uncertainties due to poorly constrained parameters, especially ...

Atmospheric Feedbacks Reverse the Sensitivity of Modeled Photosynthesis to Stomatal Function

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract Stomata mediate fluxes of carbon and water between terrestrial plants and the atmosphere. These fluxes are governed by stomatal function and can be modulated in many Earth system models by an empirical parameter within the calculation of stomatal conductance, the stomatal slope g1M $\left({g}_{1M}\right)$.

Environmental factors have a greater influence on photosynthetic capacity in C4 plants than biochemical subtypes or growth forms

New Phytologist, Volume 248, Issue 3, Page 1205-1224, November 2025.
Summary Our understanding of how photosynthetic capacity varies among C4 species and across growth and measurement conditions remains limited. We collated 1696 CO2 response curves of net CO2 assimilation rate (A/Ci curves) from C4 species grown and measured at various environmental conditions and used these data to estimate the apparent maximum ...
