Wing planform dependency on optimum supersonic airfoil
Nihon Kikai Gakkai ronbunshu, 2017 When a wing of airplane is designed, it is necessary to have knowledge regarding planforms considered their optimum airfoils in order to design efficiently, because each wing planform has both of advantage and disadvantage. In this study, the wing design

On Spatial Point Processes With Composition‐Valued Marks
International Statistical Review, EarlyView.Summary Methods for marked spatial point processes with scalar marks have seen extensive development in recent years. While the impressive progress in data collection and storage capacities has yielded an immense increase in spatial point process data with highly challenging non‐scalar marks, methods for their analysis are not equally well developed ...

JOR SPINE, Volume 9, Issue 3, September 2026.The inferior facet of the L2 vertebra and the superior facet of the L3 vertebra were harvested from ovine lumbar spines. The spatial biomechanical properties of the facet cartilage surfaces were determined by indentation mapping. Cartilage structure was spatially analyzed on a macroscopic and microscopic level.

Bootstrap based uncertainty bands for prediction in functional kriging [PDF]
Spatial Statistics, 2017 The increasing interest in spatially correlated functional data has led to the development of appropriate geostatistical techniques that allow to predict a curve at an unmonitored location using a functional kriging with external drift model that takes into account the effect of exogenous variables (either scalar or functional).

Beyond the Cascade Dams: Scale‐Dependent Effects on Zooplankton Stability in River Ecosystems
Ecology and Evolution, Volume 16, Issue 8, August 2026.Cascade dams alter river zooplankton community stability, but how regulating factors act across local and regional spatial scales is poorly understood. Using field sampling and structural equation modeling, we revealed divergent scale‐dependent responses of zooplankton stability to dams—local stability depended on biodiversity, while regional stability
