Packing several characters into one computer word is a simple and natural way to compress the representation of a string and to speed up its processing. Exploiting this idea, we propose an index for a packed string, based on a sparse suffix tree [8] with appropriately defined suffix links. Assuming, under the standard unit-cost RAM model, that a word can store up to logσ n characters (σ the alp...

A sustained dipolar magnetic field between the current sheet outer edge and magnetopause, known as a cushion region, has yet to be observed at Saturn. Whilst some signatures of reconnection occ...

To store and search genomic databases efficiently, researchers have recently started building compressed self-indexes based on grammars. In this paper we show how, given a straight-line program with r rules for a string S[1..n] whose LZ77 parse consists of z phrases, we can store a self-index for S in O(r + z log log n) space such that, given a pattern P [1..m], we can list the occ occurrences ...

Many Gram-negative bacteria, including human pathogens such as Pseudomonas aeruginosa, do not have large-channel porins. This results in an outer membrane (OM) that is highly impermeable to small polar molecules, making the bacteria intrinsically resistant towards many antibiotics. In such microorganisms, the majority of small molecules are taken up by members of the OprD outer membrane protein...

The aim of this study was to determine a suitable amount of grinding of a flexural test specimen for clinical evaluation of dental ceramics. Three dental ceramics (Crys-Cera, OCC and IPS Empress Cosmo) were selected. Five types of bar-shaped patterns were prepared for a three-point bending test, and four types of disk-shaped patterns for a biaxial flexural test. Ceramic specimens were fabricate...

BACKGROUND The outcome of postoperative high- and intermediate-risk oral cavity cancer (OCC) patients receiving helical tomotherapy (HT) remains limited. MATERIALS AND METHODS Between November 2006 and November 2012, 53 postoperative high- and intermediate-risk OCC patients treated with HT were enrolled. RESULTS The 4-year locoregional, local, and regional control rates were 66%, 76.4%, and...

The cerebral reserve hypothesis is a heuristic concept used to explain apparent protection from the onset of cerebral disease and/or cognitive decline in old age. A significant obstacle when investigating the reserve hypothesis is the absence of baseline data with which to compare current cognitive status. We tested the influence of three hypothesized proxies of reserve (education, head size an...

Estrogen deficiency and chronic alcohol consumption may have a synergistic and deleterious effect on bone tissue. Aim: To investigate the effects of estrogen deficiency associated with chronic alcohol consumption on the mandibular condyle in rats. Methods: Fifty-four female rats were first divided equally into two groups: ovariectomized (Ovx) and simulated ovariectomy (Sham). One month after th...
