Balanced Distributed Search Trees Do Not Exist

This paper is a rst step towards an understanding of the inherent limitations of distributed data structures. We propose a model of distributed search trees that is based on few natural assumptions. We prove that any class of trees within our model satis es a lower bound of (pm) on the worst case height of distributed search trees for m keys. That is, unlike in the single site case, balance in ...

Do not forget: coronary spasm does exist!

A 36-year old woman was proposed for urgent revascularization for severe left coronary disease with left main involvement diagnosed in the setting of acute coronary syndrome with ST-elevation. Considering the patient’s age and gender, coronariography was repeated under vasodilator therapy (Fig. 1, Supplementary Video 1 and 2). Coronary spasm was revealed. Supplementary material is available at ...

Cannon–thurston Maps Do Not Always Exist

We construct a hyperbolic group with a hyperbolic subgroup for which inclusion does not induce a continuous map of the boundaries. 2010 Mathematics Subject Classification: 20F67

Three-Way Systems Do Not Exist

We argue that argument encoding systems that seem to involve three syntactic core cases (nominative/absolutive, ergative, accusative) are actually common ergative or accusative systems syntactically, with overt case markers for each of the two cases that disappear in intransitive contexts. Based on evidence from Kham, Djapu, Nez Perce, Upriver Halkomelem, Dyirbal, and Pitjantjatjara, we show th...
