This paper proposes two new crossover operators for searching over discrete probability spaces. The design of the operators is considered in the light of recent theoretical insights into genetic search provided by forma analysis. A nontrivial test problem in enforcing coherency of probability estimates in cross-impact analysis highlights the utility of the designed operators. The presented oper...

The phase stability and mechanical properties of wurtzite (w)-Zr0.25Al0.75N/cubic (c)-TiN and w-Zr0.25Al0.75N/c-ZrN multilayers grown by arc evaporation are studied. Coherent interfaces with an orientation relation of c-TiN (111)[1-10]ǀ ǀ w-ZrAlN (0001)[11-20] form between ZrAlN and TiN sublayers during growth of the w-ZrAlN/c-TiN multilayer. During annealing at 1100 °C a c-Ti(Zr)N phase forms ...

OBJECTIVE Investigate the structural coherency of the 60-item version of the General Health Questionnaire via exploratory and confirmatory factor analyses. METHOD The study design is a cross-sectional survey. A random sample of 146 individuals from the city of Divinópolis-MG volunteered to participate in the present study and responded to the 60-item version of the General Health Questionnair...

Retrogression treatment is a crucial process to obtain preferential microstructure and mechanical property for aviation Al-Zn-Mg-Cu alloys. In the current work, ramping time, preservation time temperature were set as variations investigate evolution precipitation characteristics commercial alloy. The results showed that strength exhibited continuously decrease trend with enhancement of or exten...

In recent years, resin-based fluoridated sealants have been introduced, the fluoride intended as a cariespreventive ingredient. Studies of prophylaxis pastes containing glycerine or fluoride that attribute poor retention to an impervious layer produced by the fluoride and other ingredients 1, 2 have been discounted by Bogert and Garcia-Godoy3 and Koch et al. 4 using newer generations of bonding...

Understanding of the nitrogen (N) cycle and its spatial variability is important for managing ecosystems. Soil δ15N, as an important indicator of different soil nitrogen cycling processes, may provide critical information about the spatial variability in soil N cycling. The objective of this study was to examine the dominant landscape scale variability of δ15N, the location of the variability a...

Query translation in cross-language information retrieval (CLIR) can be done by employing dictionaries, aligned corpora, or machine translators. Scarcity of aligned corpora for various domains in many language pairs intensifies the importance of dictionary-based CLIR which motivates us to use only a bilingual dictionary and two independent collections in source and target languages for query tr...

Prolonged observations of moving plaids lead to bi-stable alternations between coherency and transparency. However, most studies of plaids used brief presentations and a 2AFC between the two interpretations, thus overlooking the dynamical aspect of plaid perception. In other domains, most notably binocular rivalry, it was shown that the dynamics of the bi-stable alternations reveal important in...
