We studied 23 patients suffering cerebral ischemia who also had laboratory evidence of either a lupus anticoagulant (LA) or an abnormal anticardiolipin antibody (ACA). Four patients had lupus or a lupus-like illness, three had drug-induced lupus, and 16 had no overt evidence of collagen-vascular disease. Cerebral ischemic events were multiple in 71% of the patients; two patients presented with ...

This paper extends to pomsets without auto-concurrency the fundamental notion of asynchronous cellular automata (ACA) which was originally introduced for traces by Zielonka. We generalize to pomsets the notion of asynchronous mapping introduced by Zielonka and we show how to construct a deterministic ACA from an asynchronous mapping. Our main result generalizes Buchi's theorem for nite words t...

The purpose of the current study was to determine whether a tropical ginger derived compound 1'-acetoxychavicol acetate (ACA), suppresses skin tumor promotion in K5.Stat3C mice. In a two-week study in which wild-type (WT) and K5.Stat3C mice were co-treated with either vehicle, ACA, galanga extract, or fluocinolone acetonide (FA) and tetradecanoyl phorbol acetate (TPA), only the galanga extract ...

In this study, RAND Corporation researchers assess the expected change in enrollment and premiums in the Patient Protection and Affordable Care Act (ACA)-compliant individual market in federally facilitated marketplace (FFM) states if the U.S. Supreme Court decides to eliminate subsidies in FFM states. The analysis used the Comprehensive Assessment of Reform Efforts (COMPARE) microsimulation mo...

Statistical equations for inertial particle transport in turbulent boundary layers are usually closed using the quasi-Normal approximation (QNA), but this leads to large errors when inertia is significant. Here we develop a new closure based on an asymptotic solution exact equations, referred as ACA. Results show that ACA far better agreement with direct numerical simulation (DNS) data than QNA.

BACKGROUND Although the anatomy of the A1 segment of the anterior cerebral artery (ACA) is highly variable, a callosomarginal artery (CMA) arising from the A1 segment of the ACA is rare. CASE DESCRIPTION A 27-year-old man presented with severe headache and was admitted to our hospital. Initial computed tomography (CT) showed subarachnoid hemorrhage in the basal cistern. Three-dimensional CT a...

Asynchronous cellular automata (ACA) are cellular automata that allow cells to update their states independently at random times. Because of the unpredictability of the order of update, computing on ACA is usually done by simulating a timing mechanism to force all cells into synchronicity after which well-established synchronous methods of computation can be used. In this paper, we present a mo...

Image quality of wide field observations with the ALMA has been studied with imaging simulations. Results of the simulations showed that antenna pointing errors are a serious problem for obtaining high quality images because they make a large error in visibilities in the central (u,v) hole estimated by mosaicing data processings. The ALMA Compact Array (ACA) with more than 10 smaller dishes (6-...

We have discovered that all known yeast and vertebrate small nucleolar RNAs (snoRNAs), except for the MRP/7-2 RNA, fall into two major classes. One class is defined by conserved boxes C and D and the other by a novel element: a consensus ACA triplet positioned 3 nt before the 3' end of the RNA. A role for the ACA box is snoRNA stability has been established by mutational analysis of a yeast ACA...

Ten ACA yeast small nucleolar RNAs (snoRNAs) were shown to be required for site-specific synthesis of pseudouridine psi in ribosomal RNA. A common secondary folding motif for the snoRNAs and rRNA target segments predicts that site selection involves: (1) base pairing of the snoRNA with complementary rRNA elements flanking the site of modification, and (2) identification of a uridine located at ...
