The ability to exogenously present cell-surface receptors in high-affinity conformations in a synthetic system offers an opportunity to provide host cells with protection from pathogenic toxins.This strategy requires improvement of the synthetic receptor binding affinity against its native counterpart, particularly with polyvalent toxins where clus
Orientation: The South African economy is currently at one of its lowest points in several decades, with low economic growth, coronavirus challenges and unemployment being at an all-time high.This is further aggravated by the many challenges the economy faces, such as the lack of public sector programs to stimulate sustainable growth and sequal ecl
Non-causal correlations certify the lack of a definite causal order among localized space-time regions.In stark contrast iphone 13 price dallas to scenarios where a single region influences its own causal past, some processes that distribute non-causal correlations satisfy a series of natural desiderata: logical consistency, linear and reversible d
Abstract We present a new operator in the ambitwistor string which glues together correlators with fewer points or of lower genus.It underpins the recursive construction of tree-level CHY scattering amplitudes by Dolan & Goddard, as well as the computation of loop integrands on iphone 13 dallas a Riemann sphere by Geyer et al.The gluing operator is
