The fusion reactions $^{12}\mathrm{C}(^{12}\mathrm{C},\ensuremath{\alpha})^{20}\mathrm{Ne}$ and $^{12}\mathrm{C}(^{12}\mathrm{C},p)^{23}\mathrm{Na}$ have been studied from $E=2.10$ to 4.75 MeV by $\ensuremath{\gamma}$-ray spectroscopy using a C target with ultralow hydrogen contamination. deduced astrophysical $S(E{)}^{*}$ factor exhibits new resonances at $E\ensuremath{\le}3.0\text{ }\text{ }\mathrm{MeV}$, in particular, strong resonance $E=2.14\text{ which lies the high-energy tail of...
Abstract The origin of giant lode gold deposits Mesozoic age in the North China craton (NCC) is enigmatic because high-grade metamorphic ancient crust would be highly depleted gold. Instead, lithospheric mantle beneath likely source gold, which may have been anomalously enriched by metasomatic processes. However, role enrichment and metasomatism remains unclear. Here, we present comprehensive data on platinum group element contents xenoliths (n = 28) basalts 47) representing temporal...
Electro-optical control of on-chip photonic devices is an essential tool for efficient integrated photonics. Lithium niobate on insulator (LNOI) emerging platform photonics due to its large electro-optic coefficient and high nonlinearity. Integrating quantum emitters into LNOI would extend their versatility in classic computing communication. Here, we incorporate rare-earth ion (REI) electro-optical tunable lithium niobite (LN) thin films demonstrate LN microcavities coupled REIs over a...
The relationship between diffusion of individual species and creep silicates is unclear has long been debated, factually anchored by the central observation that activation energies for are higher than energy any species. There have numerous attempts to explain this difference. New advances in experimental technology enable us demonstrate difference does not exist was an artefact limited resolution earlier studies – Si olivine identical, 530 kJ/mol. This allows mechanism be understood as one...

The contribution of Escherichia coli hemolysin (ECH) to bacterial virulence has been considered mainly in context with its hemolytic properties. We here report that this prevalent cytolysin is the most potent leukocidin known date. Very low concentrations (approximately 1 ng/ml) ECH evoke membrane permeability defects PMN (2-10 x 10(6) cells/ml) leading an efflux cellular ATP and influx propidium iodide. attacked cells do not appear repair lesions.
