Quantum walled Brauer-Clifford superalgebras
Benkart, G.,Guay, N.,Jung, J.H.,Kang, S.J.,Wilcox, S. Academic Press 2016 Journal of algebra Vol.454 No.-
<P>We introduce a new family of superalgebras, the quantum walled Brauer-Clifford superalgebras BCr,s (q). The superalgebra BCr,s (q) is a quantum deformation of the walled Brauer-Clifford superalgebra BCr,s and a super version of the quantum walled Brauer algebra. We prove that BCr,s (q) is the centralizer superalgebra of the action of U-q (q(n)) on the mixed tensor space V-q(r,s) = V-q(circle times r) circle times (V-q*)(circle times s) when n >= r + s, where V-q = C(q)((n\n)) is the natural representation of the quantum enveloping superalgebra U-q(q(n)) and V-q* is its dual space. We also provide a diagrammatic realization of BCr,s (q) as the (r, s)-bead tangle algebra BTr,s (q). Finally, we define the notion of q-Schur superalgebras of type Q and establish their basic properties. (C) 2015 Published by Elsevier Inc.</P>

Background and Purpose Patients with nonvalvular atrial fibrillation (NVAF) who survive an intracranial hemorrhage (ICH) have an increased risk of ischemic stroke and systemic embolism (IS/ SE). We investigated whether starting oral anticoagulants (OACs) among older NVAF patients after an ICH was associated with a lower risk of IS/SE and mortality but offset by an increase in major bleeding. Methods We assembled a patient cohort from the Quebec Régie de l’Assurance Maladie du Québec (RAMQ) and Med-Echo administrative databases. We identified older adults with NVAF from 1995 to 2015. All patients with incident ICH and discharged in community were included. Patients were categorized according to OAC exposure. Outcomes included IS/SE, all-cause mortality, recurrent ICH and major bleeding after a quarantine period of 6 weeks. Crude event rates were calculated at 1-year of follow-up, and Cox proportional hazard models with a time-dependent binary exposure were used to assess adjusted hazard ratios (AHRs). Results The cohort of 683 NVAF patients with ICH aged 83 years on average. The rates (per 100 person-years) for IS/SE, death, ICH and major bleeding were 3.3, 40.6, 11.4, and 2.7 for the no OAC group; and 2.6, 16.3, 5.2, and 5.2 for OAC group, respectively. The AHR for IS/SE and death was 0.10 (95% confidence interval [CI], 0.05 to 0.21), 0.43 (95% CI, 0.19 to 0.97) for recurrent ICH and 1.73 (95% CI, 0.71 to 4.20) for major extracranial bleeding comparing OAC exposure to non-exposed. Conclusions Initiating OAC after ICH in older individuals with NVAF is associated with a reduction of IS/SE and mortality and a trend in recurrent ICH supporting its use after ICH.

Escape behaviour is a critical component of invertebrate life history but is poorly studied. Flight initiation distance (FID) indexes escape propensity, and is wellstudied in vertebrates but is entirely unstudied in Lepidopterans, despite their obvious escape behaviour. Here we test two general principles regarding FID as derived from studies of vertebrates to examine if they apply to Sri Lankan butterflies: 1) that FID is a species-specific trait and 2) that FID increases with Starting Distance, the distance at which the experimenter begins an approach. We collected 295 FIDs from 17 species and find that 1) FIDs are a tractable way of indexing butterfly escape and 2) both the general principles tested apply to butterfly escape. We also present FIDs of these species to encourage further data collection and comparative analysis of butterfly escape.
