Abstract F-theory/heterotic duality is formulated in the stable degeneration limit of a K3 fibration on the F-theory side.In this note, we analyze the structure of the stable degeneration limit.We discuss whether stable degeneration exists for pairs of rational elliptic surfaces.We demonstrate that, when two rational elliptic surfaces have an ident

Assessing the distribution of chloroplast DNA (cpDNA) haplotype variation is useful for studying the phylogeography of angiosperms.In the last two decades the cpDNA phylogeography of white oaks in Europe has rosaliac ar intense visible facial redness serum been extensively studied, mostly based on the PCR-RFLP technique.However, PCR-RFLPs have low

History, which is tablet displayschutz subsumed under Social and Humanity Sciences, is a field that closely concerns all branches of sciences.History is a verified set of facts.In the past sense, it is a continuous dimension of human consciousness, the institutions and values of the society and the absolute component of the patterns outside these.I

Microorganisms often navigate a complex environment composed of a viscous fluid with suspended microstructures such as elastic polymers and filamentous networks.These microstructures can have similar length scales to the microorganisms, leading to complex swimming dynamics.Some microorganisms secrete enzymes that dynamically change the elastic prop

In this paper, I argue that bare plural noun phrases in Spanish unambiguously denote case of whispering angel properties of individuals.I begin by using evidence from their incompatibility with kind-level predicates to show that Spanish bare plurals do not denote kinds.I then point to crucial ways in which their interaction with quantifiers is unli
