Understanding how the Viking societies were impacted by past climate variability and they adapted to it has hardly been investigated. Here, we have carried out a new multi-proxy investigation of lake sediments, including geochemical palynological analyses, reconstruct changes in temperature agricultural practices pre-Viking Southeastern Norway during period between 200 1300 CE. The periods 200–...

The amplitude of the rabbit scotopic electroretinogram (ERG) is notoriously labile both in day-to-day variations in the same animal1 as well as in the wide range seen in normal controls. This seriously impairs the rabbit's usefulness as a model in long-term experiments. Part of the reason for this difficulty appears to lie in the traditional methods of obtaining and assessing adaptation prepara...

Recently, we proposed an improvement to the eigenvoice (EV) speaker adaptation called kernel eigenvoice (KEV) speaker adaptation. In KEV adaptation, eigenvoices are computed using kernel PCA, and a new speaker’s adapted model is implicitly computed in the kernel-induced feature space. Due to many online kernel evaluations, both adaptation and subsequent recognition of KEV adaptation are slower ...

Future ocean acidification has the potential to adversely affect many marine organisms. A growing body of evidence suggests that many species could suffer from reduced fertilization success, decreases in larval-and adult growth rates, reduced calci-fication rates, metabolic depression and even mortality when being exposed to near-5 future levels (year 2100 scenarios) of ocean acidification. Lit...

objectives: it is not clear what type of pre-crimped crown is more successful in achieving greater marginal adaptation following re-crimping. this study aimed to assess the changes in the circumference of 3m espe and mib pre-crimped stainless steel crowns (sscs) for the primary maxillary and mandibular first and second molars following re-crimping. materials and methods: this was an in-vitro, e...
