Higher-order interactions are important for protein folding and assembly. We introduce the concept of interhelical three-body interactions as derived from Delaunay triangulation and alpha shapes of protein structures. In addition to glycophorin A, where triplets are strongly correlated with protein stability, we found that tight interhelical triplet interactions exist extensively in other membr...

While our knowledge of the dental caries process and its prevention has greatly advanced over the past fifty years, it is fair to state that the management of this disease at the level of the individual patient remains largely empirical. Recommendations for fluoride use by patients at different levels of caries risk are mainly based on the adage that more is better. There is a general understan...

Selective functionalization reactions of aromatic and heteroaromatic halides with carbon, oxygen, and nitrogen nucleophiles have attracted much attention in the last decades. In addition to typical metal-catalyzed coupling reactions, direct functionalization of aryl halides through the formation of Grignard reagents offer new ways for the efficient construction of biologically interesting carbo...

Salmonella enterica serovar Typhimurium genome encodes 13 fimbrial operons. Most of the fimbriae encoded by these operons are not produced under laboratory conditions but are likely to be synthesized in vivo We used an in vivo expression technology (IVET) strategy to identify four fimbrial operons, agf, saf, sti, and stc that are expressed in the spleen. When any three of these operons were del...

Psychological empowerment is a construct with multifaceted character composed of four basic cognitions (impact, competence, meaning, and self-determination), which goes beyond simple delegation power. The impact in different fields Psychology has been important due to the proven relations maintained other well-founded psychological variables scientific literature, because positive consequences ...

The initial aim of this project was to combine (1) wavelet-based image quality enhancement techniques that have recently been introduced in the literature with (2) our previously developed color remapping technique to enhance the articulation of details in color fused multiband nighttime imagery. After implementing several of the wavelet super-resolution techniques, we observed that their perfo...
