Open AccessDynamical decoupling of electron spins in phosphorus-doped silicon
Quantum coherence is an important enabling feature underpinning quantum computation. However, because of couplings with its noisy surrounding environment, qubits suffer from the decoherence effects. The dynami...

Open AccessMolybdenum isotopic composition as a tracer for low-medium temperature hydrothermal ore-forming systems: A case study on the Dajiang** pyrite deposit, western Guangdong Province, China
Little is known about the range or controls on the molybdenum isotopic composition of low-medium temperature hydrothermal ore-forming systems. We present molybdenum isotope data from 12 hydrothermal syndeposit...

Open AccessEffects of inorganic arsenic on growth and microcystin production of a Microcystis strain isolated from an algal bloom in Dianchi Lake, China
Our previous data have shown that inorganic arsenic concentrations were high in Dianchi Lake, China, where Microcystis blooms often occur. To explore the relationship between arsenic and the growth of Microcystis

Open AccessAsymmetric energy flow in coupled nonlinear LC transmission line
We constructed a coupled LC transmission line and studied the propagation of waves in it. We found asymmetric energy flow when we changed the driving conditions at the boundary. We analyzed this change and believ...

Open AccessCalcium isotope fractionation and its controlling factors over authigenic carbonates in the cold seeps of the northern South China Sea
In this study, we analyzed stable calcium isotope results of authigenic carbonates from two cold seep areas of the Dongsha area and the Baiyun Sag in the northern South China Sea. The stable isotopes of carbon...

Open AccessPhase-error restraint with the empirical mode decomposition method in phase measurement profilometry
Phase measurement profilometry (PMP) uses a digital projector and a camera for 3D shape measurement. However, the nonlinear response of the measurement system causes the captured perfect sinusoidal fringe patt...
