Security Enhancement Through Compiler-Assisted Software Diversity With Deep Reinforcement Learning
Traditional software defenses take corresponding actions after the attacks are discovered. The defenders in this situation are comparatively passive because the attackers may try many different ways to find vulnerability and...
Transformation and Identification between Two Generations Shanghai Dreams as a Political Melodrama
Xiaoping Wang
Mar 27, 2018
Shanghai Dreams (Qinghong青红), directed by Wang Xiaoshuai (王小帅,1966- ), is the first work created by a famed Chinese sixth-generation auteur to deal with the subject of construction of the “third line of defense” by focusing on...
Enhanced light extraction by photonic quasi-crystals in GaN blue LEDs
The far-field profile of photonic quasi-crystal patterned and unpatterned LEDs, fabricated from commercial epitaxial substrates by electron beam lithography, has been measured prior to lapping and dicing. Emission enhancements...

Computation of three-dimensional flexural-gravity solitary waves in arbitrary depth
Fully-localised solitary waves propagating on the surface of a three-dimensional ideal fluid of arbitrary depth, and bounded above by an elastic sheet that resists flexing, are computed. The cases of shallow and deep water are...

Environmental Sustainability
Without embracing environmental sustainability (ES), the universal concept of Sustainable Development Goals (SDGs) cannot be achieved in today's world. As an inseparable part of SDGs, ES can help the nations to fulfil the goal...
Differentiable surface splatting for point-based geometry processing
We propose Differentiable Surface Splatting (DSS), a high-fidelity differentiable renderer for point clouds. Gradients for point locations and normals are carefully designed to handle discontinuities of the rendering...

Tracing the origin of heterogeneity and symmetry breaking in the early mammalian embryo.
A fundamental question in developmental and stem cell biology concerns the origin and nature of signals that initiate asymmetry leading to pattern formation and self-organization. Instead of having prominent pre-patterning...

On Conformal Gauss Maps
Francis Burstall
Dec 31, 2019

 We characterise the maps into the space of 2-spheres in S n that are the conformal Gauss maps of conformal immersions of a surface into S n. In particular, we give an invariant formulation and efficient proof of a...
