Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells

open access: yesAdvanced Functional Materials, EarlyView.
In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

On the Existence of Kernel Function for Kernel-Trick of k-Means [PDF]

open access: yes, 2017
This paper corrects the proof of the Theorem 2 from the Gower’s paper [1, p. 5]. The correction is needed in order to establish the existence of the kernel function used commonly in the kernel trick e.g. for k-means clustering algorithm, on the grounds of distance matrix.
