Shadow of a naked singularity without photon sphere [PDF]
It is generally believed that the shadows of either a black hole or naked singularity arise due to photon spheres developing in these spacetimes. Here we propose a new spherically symmetric naked singularity spacetime solution of Einstein equations which

Classification of flat bands according to the band-crossing singularity of Bloch wave functions [PDF]
We show that flat bands can be categorized into two distinct classes, that is, singular and non-singular flat bands, by exploiting the singular behavior of their Bloch wave functions in momentum space.

Foucault et la phronesis : les cas à l’épreuve de la singularité
This article proposes to trace the presence of a discreet but continuous critical engagement with the Aristotelian category of phronesis in Foucault’s work.

Optimum Seeking of Redundant Actuators for M-RCM 3-UPU Parallel Mechanism
The singularity problem brings troubles to the design and application for the parallel mechanism. Currently, redundant actuation is one of the useful methods to solve this singularity problem. However, faced to the numerous joints in a parallel mechanism,

On stress singularity near the tip of a crack with surface stresses
In the framework of the simplified linear Gurtin–Murdoch surface elasticity we discuss a singularity of stresses and displacements in the vicinity of a mode III crack.

Monotonicity of nonpluripolar products and complex Monge–Ampère equations with prescribed singularity [PDF]
We establish the monotonicity property for the mass of non-pluripolar products on compact Kahler manifolds, and we initiate the study of complex Monge-Ampere type equations with prescribed singularity type. Using the variational method of Berman-Boucksom-
