White-opaque switching in the human fungal pathogen Candida albicans is an alternation between two distinct types of cells, white and opaque. White and opaque cells differ in their appearance under the microscope, the genes they express, their mating behaviors, and the host tissues for which they are best suited. Each state is heritable for many generations, and switching between states occurs ...

Opaque predicate obfuscation, a low-cost and stealthy control flow obfuscation method to introduce superfluous branches, has been demonstrated to be effective to impede reverse engineering efforts and broadly used in various areas of software security. Conventional opaque predicates typically rely on the invariant property of well-known number theoretic theorems, making them easy to be detected...

Experiment 1 examined whether the semantic transparency of an English unspaced compound word affected how long it took to process it in reading. Three types of opaque words were each compared with a matched set of transparent words (i.e. matched on the length and frequency of the constituents and the frequency of the word as a whole). Two sets of the opaque words were partially opaque: either t...

PURPOSE To determine the characteristics and risk factors for occurrence of opaque bubble layer (OBL) during femtosecond laser-assisted flap creation for LASIK. METHODS One hundred ninety-eight eyes of 102 consecutive patients who underwent LASIK flap creation performed with the Alcon WaveLight FS200 laser (Alcon Laboratories, Inc., Fort Worth, TX) were retrospectively analyzed in a cohort st...

T HE inferiority of Colombian floury-2 corn to Colombian opaque-2 corn as the only energy-protein source for growing rats and swine has been reported (Maner et al., 1971). Cromwell et al. (1968) showed that floury-2 corn is superior to opaque-2 corn for growth of chicks because of the methionine deficiency of opaque-2 corn relative to the chick's methionine requirement. The pig and rat have low...

The aim of this study was to evaluate the depth of curing of 10 contemporary blue light-activated dental flowable materials at several opacities, influenced by different irradiation times using FT-IR spectroscopy. Fifty-five specimens (n = 5) with a 5-mm diameter and 1-mm thickness of translucent (Opallis Flow T), yellowed (Master Flow A2; Opallis Flow A2; Natural Flow A2; Fluroshield Yellowed)...

Photothermal radiometry has been proved being a versatile tool for the non-contact and non-destructive material inspection in near-surface zones. Although these near-surface areas represent only a few percent of the workpiece’s volume, they influence significantly its quality, functional behaviour, reliability and life time. In particular, they determine decisively the mechanical properties of ...
