Many persistent viral infections are characterized by a hypofunctional T cell response and the upregulation of negative immune regulators.These events occur days after the initiation of infection.However, the very early host-virus interactions that determine the establishment of viral persistence remain poorly uncharacterized.Here we show that to e
The emerging BeiDou navigation satellite system has contributed to global precise positioning and has recently moved toward space-borne applications.However, the contribution of BeiDou on LEO orbit determination applications is limited by the poor precision of the GEO satellite orbit and clock products.Current researches suggest that BeiDou GEO sat
Though instrumental in numerous disciplines, context has no universally accepted definition.In specialized knowledge resources it is timely and necessary to parameterize context with a view to more effectively facilitating knowledge representation, understanding, and acquisition, the main aims of terminological knowledge bases.This entails distingu
Increasing sand temperatures resulting from climate change may negatively impact sea turtle nests by altering sex ratios and decreasing reproductive output.We analyzed the effect of nest shading and watering on sand temperatures as climate mitigation strategies in a beach hatchery at Playa Grande, Costa Rica.We set up plots and placed thermocouples
