We propose and test a fairly simple idea that could account for the blazar sequence: all jets are launched with similar energy per baryon, independently of their power. For instance, flat-spectrum radio quasars (FSRQs), most powerful jets, manage to accelerate high bulk Lorentz factor, as observed in radio. As result, emission region will have rather modest magnetization which induce steep part...

Graph Convolutional Networks (GCNs) have received increasing attention in the machine learning community for effectively leveraging both content features of nodes and linkage patterns across graphs various applications. As real-world are often incomplete noisy, treating them as ground-truth information, which is a common practice most GCNs, unavoidably leads to sub-optimal solutions. Existing e...

We discuss Shult’s Haircut Theorem, which unifies several recognition theorems for Lie geometries. point out why the conclusion of original version (published posthumously without his final scrutiny) cannot be drawn from hypotheses and state prove a corrected version, obtained by restricting one condition relaxing two other conditions.
