Random Diophantine equations in the primes
Mathematika, Volume 72, Issue 3, July 2026.Abstract We consider equations of the form a1x1k+⋯+asxsk=0$a_{1}x_{1}^{k}+\cdots +a_{s}x_{s}^{k}=0$ where the variables xi$x_{i}$ are all taken to be primes. We define an analogue of the Hasse principle for solubility in the primes (which we call the prime Hasse principle), and prove that, whenever k⩾2$k\geqslant 2$, s⩾3k+2$s\geqslant 3k+2$, this holds

Ecology and Evolution, Volume 16, Issue 6, June 2026.Normal or baseline scenario with parameterization from the literature. The green line indicates the CPS based on the decision tree. The blue hatched area indicates the transition period of the model where there are increasing number of wasps present at the end of the simulations and an indication that the model is becoming more stable.

Resilience and plant growth forms 40 years after a volcanic disturbance
Ecosphere, Volume 17, Issue 6, June 2026.Abstract Resilience represents a critical concept in ecology; yet, quantitative assessment of resilience in response to disturbance is rare, even for widely recognized growth forms. Plant groups based on deciduousness, clonality, morphology, and Raunkiaer life form could predict inertia to major disturbances and subsequent resilience.

Evolution of Soil Surface Roughness and Its Influence on Flow Pathways and Sediment Connectivity
Water Resources Research, Volume 62, Issue 6, June 2026.Abstract Soil surface roughness (RR) and its spatiotemporal variations are important for understanding soil erosion process, but how the erosion‐induced evolution of RR affects flow pathways and sediment connectivity patterns remains unclear. This study used high‐resolution topographic data sets from a long‐term rainfall simulation experiment in semi ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.Abstract The three‐dimensional (3D) gravity inversion problem is the process of delineating the volumetric mass distributions from the surface gravity anomalies. Recently, many innovative Convolutional Neural Network (CNN) based algorithms have found some success in reduction of computation costs and delineation of sharper boundaries of causative ...

Rhythm, contagion, "cosmic race”
FedroIn his text Pitágoras. Una teoría del ritmo (1921), the Mexican philosopher José Vasconcelos carries out an interesting rereading of ancient Pythagoreanism to reorient the symbolic-abstract direction of Western thought, which seems to pave a new line of

A review of Aristotle’s claim regarding Pythagoreans fundamental Beliefs: All is number?
Filosofia Unisinos, 2016 The question-statement, “All is number?”, the title of Zhmud’s famous 1989 article in Phronesis, opens a challenge to the extremely important Aristotelian testimony that “all is number” was the fundamental definition of Pythagorean philosophy.

Molecular Ecology, Volume 35, Issue 12, June 2026.ABSTRACT In high‐arctic semi‐desert ecosystems, climate projections suggest a doubling of the current ≤ 250 mm annual precipitation by 2075, increasingly falling as summer rain. This is expected to affect the balance among fungal ecological groups and stimulate decomposition over build‐up of soil organic matter.
