Questions How does desert grassland vegetation respond to long-term grazing removal? Is grass response the result of differences in number or size plants? Does differ over time and relation precipitation patterns? Location Santa Rita Experimental Range, southwestern United States. Methods Four times between 2011 2020, we measured cover woody plants native non-native perennial grasses, density, ...

Smart grid is gradually replacing traditional with two-way communication and improved management. Besides the efficiency reliability it brings, smart inevitably fraught rampant physical cyber-attack. Although several unclonable function (PUF)-based schemes have been proposed, they are unsuited to end-edge-cloud hierarchical grid. This paper proposes a PUF-based batch authentication key agreemen...

Many CAN-based session key sharing approaches are based on the group scheme, which can easily lead advanced adversaries to infiltrate all ECUs (electronic control units) in network if is leaked. To address above problem, we propose a provable secure distribution protocol improved NSSK (Needham–Schroeder shared key) for in-vehicle CAN network. We applied mechanisms of message authentication and ...

The diet of Saguinus midas is characterised by analysis of stomach contents samples on an annual and seasonal basis. The diet comprises significant proportions of both fruit and insects all year round, although fruit use shows important seasonal variations. The tamarins reduce their use of fruit resources during the peak fruiting season and instead exploit increased opportunities for insectivor...

There is a surprising degree of overlapping structure evident across the languages of the world. One factor leading to cross-linguistic similarities may be constraints on human learning abilities. Linguistic structures that are easier for infants to learn should predominate in human languages. If correct, then (a) human infants should more readily acquire structures that are consistent with the...

A key component in building trusted computing services is a highly secure anchor that serves as Root-of-Trust (RoT). There are several works conduct formal analysis on the security of such commodity RoTs (or parts it), and also few ones devoted to verifying service whole. However, most existing schemes try verify without differentiating internal cryptography mechanisms underlying hardware token...
