The function of nonlinear phenomena in meerkat alarm calls.
Nonlinear vocal phenomena are a ubiquitous feature of human and non-human animal vocalizations. Although we understand how these complex acoustic intrusions are generated, it is not clear whether they function adaptively for the animals producing them. One explanation is that nonlinearities make calls more unpredictable, increasing behavioural responses and ultimately reducing the chances of ha...
متن کاملFail-Stop Signatures
Fail-stop signatures can briefly be characterized as digital signatures that allow the signer to prove that a given forged signature is indeed a forgery. After such a proof has been published, the system can be stopped. This type of security is strictly stronger than that achievable with ordinary digital signatures as introduced by Diffie and Hellman in 1976 and formally defined by Goldwasser, ...
متن کاملMeerkat close calling patterns are linked to sex, social category, season and wind, but not fecal glucocorticoid metabolite concentrations
It is well established that animal vocalizations can encode information regarding a sender's identity, sex, age, body size, social rank and group membership. However, the association between physiological parameters, particularly stress hormone levels, and vocal behavior is still not well understood. The cooperatively breeding African meerkats (Suricata suricatta) live in family groups with des...
متن کاملFail-Stop Signatures Without Trees
We construct the first fail-stop signature scheme where neither the signature length nor the length of the public key grows as a function of the number of messages that can be signed with one key. The computation needed for signing and testing is reduced similarly. This removes one of the main differences between the complexity of ordinary signature schemes and previous fail-stop signature sche...
متن کاملClose, but not close enough
The most recent European Society of Cardiology (ESC) guidelines recommend primary percutaneous coronary intervention (PCI) as the preferred treatment for ST-segment elevation myocardial infarction (STEMI) whenever it is available within 90–120 min of the first medical contact [1]. However, timing of symptom onset appears to be hard to adjudicate precisely, and 'ischaemic time' thereby usually e...
