A lower bound for the size of a complete cap of the polar space H(n, q2) associated to the non-degenerate Hermitian variety Un is given; this turns out to be sharp for even q when n = 3. Also, a family of caps of H(n, q2) is constructed from Fq2-maximal curves. Such caps are complete for q even, but not necessarily for q odd.

A family of caps constructed by Ebert, Metsch and T. Szönyi [8] results from projecting a Veronesian or a Grassmannian to a suitable lower-dimensional space. We improve on this construction by projecting to a space of much smaller dimension. More precisely we partition PG(3r − 1, q) into a (2r − 1)−space, an (r − 1)−space and qr − 1 cyclic caps, each of size (q2r − 1)(q − 1). We also decide whe...

We study 2009 and 2020 dark trading for U.S. stocks. Dark is lower when volume low, volatility high, in periods of markets stress. pools are more active large caps, while internalization common small caps. Traders use to jump the queue caps 2009, avoid crossing spread both years. Internalization higher spreads wide depth high. pool improves but worsens market quality 2020. discuss explanations ...

Introduction Cryopyrin-associated periodic syndromes (CAPS) are the rare hereditary autoinflammatory diseases. CAPS include three similar conditions are distinguished which lie along a phenotypical continuum with increasing levels of severity: familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS) and CINCA/ NOMID. Distinguishing features include cutaneous, neurological, op...

CONTEXT Catastrophic antiphospholipid syndrome (CAPS) is a rare life-threatening autoimmune disease characterized by disseminated intravascular thrombosis resulting in multiorgan failure. EVIDENCE ACQUISITIONS Directory of Open Access Journals (DOAJ), Google Scholar, PubMed (NLM), LISTA (EBSCO) and Web of Science have been searched. RESULTS CAPS is due to antiphospholipid antibodies directe...

BACKGROUND Emerging evidence suggests that "adaptive" induction of autophagy (the cellular process responsible for the degradation and recycling of proteins and organelles) may confer a cardioprotective phenotype and represent a novel strategy to limit ischemia-reperfusion injury. Our aim was to test this paradigm in a clinically relevant, large animal model of acute myocardial infarction. ME...

BACKGROUND Under conventional heart failure therapy, inflammatory cardiomyopathy typically has a progressive course, indicating a need for alternative therapeutic strategies to improve long-term outcomes. We recently isolated and identified novel cardiac-derived cells from human cardiac biopsies: cardiac-derived adherent proliferating cells (CAPs). They have similarities with mesenchymal stroma...

ID: 18837 Title: Improved Collimator Scattering Factor (Sc) Measurements for Small Fields Using Build-Up Caps in Robotic Radiosurgery Purpose:The Monte Carlo calculation algorithm in the MultiPlan (Accuray, Palo Alto, CA) treatment planning system used for CyberKnife (Accuray) robotic radiosurgery requires in-air measurements. In this study, results were compared for the impact of build-up caps...

Background CAPS is an orphan auto-inflammatory disease, generally diagnosed in childhood that requires life-long treatment. Canakinumab, a fully human anti-IL-1b antibody, has previously demonstrated rapid, complete and sustained response in CAPS patients. Aim To compare dosing patterns of canakinumab in pediatric and adult CAPS patients of a predominantly Western population (WP) vs Japanese pa...
