Although a cultural and chronometric framework for the introduction of agriculture in East Timor has long been proposed, little is known about the exact history of early plant use in the island.

We introduce bonsai trees, a lattice-based cryptographic primitive that we apply to resolve some important open problems in the area. Applications of bonsai trees include: • An efficient, stateless ‘hash-and-sign’ signature scheme in the standard model (i.e., no random oracles), and • The first hierarchical identity-based encryption (HIBE) scheme (also in the standard model) that does not rely ...

Abstract Key message Large bulges formed around bark-included branch junctions can be conceived of as ‘compensatory growth’. Despite Claus Mattheck’s hypothesis that ‘the larger the bulges, more likely junction is to fail’, this study identifies extent defect inside such key information in predicting junction’s load-bearing capacity. A currently prevalent rule European arboriculture if a tree a...
