Formalizing Convex Hull Algorithms [PDF]
, 2001 We study the development of formally proved algorithms for computational geometry. The result of this work is a formal description of the basic principles that make convex hull algorithms work and two programs that implement convex hull computation and have been automatically obtained from formally verified mathematical proofs.

Advanced Science, EarlyView.Human neutrophils exist as two epigenetically imprinted subtypes defined by stable CD177 expression or absence — a ratio that persists across time, circadian rhythms, and inflammation. CD177− neutrophils display a distinct molecular landscape enriched in arginase 1 and lipid metabolism markers, accumulate in head‐and‐neck tumors, and associate with ...

Machine‐Learning Framework for Designing Stable Interfaces in All‐Solid‐State Lithium‐Ion Batteries
Advanced Science, EarlyView.A data‐driven strategy is developed to discover coating materials for all‐solid‐state lithium batteries. Using calculations of interfacial reactivity, unsupervised pattern recognition, and machine‐learning prediction, the study identifies low‐reactivity compositional patterns and screens new lithium‐based oxide and polyanion candidates, extending ...

Hyperplane separability and convexity of probabilistic point sets
Journal of Computational Geometry, 2017 We describe an $O(n^d)$-time algorithm for computing the exact probability that two $d$-dimensional probabilistic point sets are linearly separable, for any fixed $d \geq 2$.

Advanced Science, EarlyView.This work visualizes local variations in luminescence and relates them to nanoscale chemical inhomogeneities in single InxGa1−xN quantum wells. We demonstrate that the elemental segregation is only inherent to quantum wells with high indium content. Density functional theory shows this to be the result of strain‐induced phase stabilization, explaining ...

Spatially Organized Human Ovarian Spheroids Instruct Endometrial Morphogenesis
Advanced Science, EarlyView.A spatially organized human follicle‐like spheroid (SPHEGaT) composed of granulosa cells (GCs) and stromal‐derived theca‐like cells (TLCs) establishes sustained steroidogenesis in vitro. When co‐cultured with human endometrial organoids (EMOs), estradiol (E2) and progesterone (P4) exchange induces secretory/progesterone‐responsive differentiation ...

Dynamic Planar Convex Hull [PDF]
, 2019 In this article, we determine the amortized computational complexity of the planar dynamic convex hull problem by querying. We present a data structure that maintains a set of n points in the plane under the insertion and deletion of points in amortized ...
