Geometric continuous patch complexes [PDF]
, 1987 A theory of geometric continuity of arbitrary order is presented. Conditions of geometric continuity at a vertex where a number of patches meet are investigated.

Raychaudhuri Equation, Geometrical Flows and Geometrical Entropy [PDF]
Symmetry, 2021 The Raychaudhuri equation is derived by assuming geometric flow in space–time M of n+1 dimensions. The equation turns into a harmonic oscillator form under suitable transformations. Thereby, a relation between geometrical entropy and mean geodesic deviation is established.

A Convolutional Neural Network Approach to the Classification of Engineering Models
IEEE Access, 2021 This paper presents a deep learning approach for the classification of Engineering (CAD) models using Convolutional Neural Networks (CNNs). Owing to the availability of large annotated datasets and also enough computational power in the form of GPUs ...

Larger cells have relatively smaller nuclei across the Tree of Life
Evolution Letters, 2021 Larger cells have larger nuclei, but the precise relationship between cell size and nucleus size remains unclear, and the evolutionary forces that shape this relationship are debated.

CoRR, 2019 We study the following separation problem: Given a collection of colored objects in the plane, compute a shortest "fence" $F$, i.e., a union of curves of minimum total length, that separates every two objects of different colors. Two objects are separated if $F$ contains a simple closed curve that has one object in the interior and the other in the ...

Ecology and Evolution, 2021 Competition and metabolism should be linked. Intraspecific variation in metabolic rates and, hence, resource demands covary with competitive ability.

Mapping the correlations and gaps in studies of complex life histories
Ecology and Evolution, 2023 For species with complex life histories, phenotypic correlations between life‐history stages constrain both ecological and evolutionary trajectories.

Evolutionary Applications, 2023 Most marine organisms have complex life histories, where the individual stages of a life cycle are often morphologically and ecologically distinct. Nevertheless, life‐history stages share a single genome and are linked phenotypically (by “carry‐over ...
