A set of multicomponent perovskite oxide nanoparticles based on La1-xSrxCo1-yFeyO3-δ(LSCF) were prepared by a simple chemical precipitation method for application in low temperature solid oxide fuel cells (LT-SOFC) as cathode materials.  The precursor materials used in this synthesis were lanthanum nitrate hexahydrate [La(NO3)<su...

Rapid, sensitive, and highly specific flow-cytometric assays were developed for the detection of the top six non-O157 Shiga toxin-producing Escherichia coli (STEC) O groups in ground beef. The analytical sensitivity of the assays was 2 × 10(3) target cells in a bacterial mixture of 10(5) CFU/ml, and the limit of detection in ground beef was 1 to 10 CFU following 8 h of enrichment. The assays ma...

We demonstrate initialization by joint measurement of two transmon qubits in 3D circuit quantum electrodynamics. Homodyne detection of cavity transmission is enhanced by Josephson parametric amplification to discriminate the two-qubit ground state from single-qubit excitations nondestructively and with 98.1% fidelity. Measurement and postselection of a steady-state mixture with 4.7% residual ex...

Two Cu-Co and Co3O4 oxides were synthesized by the conventional sol-gel auto-combustion and their physical-chemical properties were characterized by XRD, FTIR, SEM, TPR and XPS. The XRD results indicated that copper-cobalt oxide appeared in a mixture form of Cu0.15Co2.85O4 spinel and CuO phases, whereas the cobalt oxide exhibited in the pure form of Co3O4 spinel. The FTIR approved the formation...

From the presented experimental data of two CO2-rich mixtures containing SO2 and CO as impurities anthropogenic CO2, we evaluated impact simultaneous presence these on transport, injection storage carbon capture (CCS) technology. We determined density, vapor-liquid equilibrium speed sound a cocapture mixture (non-purified captured flue gas) [CO2 + 4.93 mol% 3.01 CO] representative European emis...

Field trials were conducted to test the effectiveness of a gas exploding device called “Rodentorch” in reducing pest populations of ground squirrels and prairie dogs. Ignition of a propane/oxygen mixture injected for 30 seconds into burrows reduced prairie dog activity 13.0%. Doubling the injection time in prairie dog burrows to 60 seconds resulted in a 63.3% reduction. Reduction in ground squi...

We create fermionic dipolar ^{23}Na^{6}Li molecules in their triplet ground state from an ultracold mixture of ^{23}Na and ^{6}Li. Using magnetoassociation across a narrow Feshbach resonance followed by a two-photon stimulated Raman adiabatic passage to the triplet ground state, we produce 3×10^{4} ground state molecules in a spin-polarized state. We observe a lifetime of 4.6 s in an isolated m...

Modeling and predicting co-occurrences of events is a fundamental problem of unsupervised learning. In this contribution, we develop a general statistical framework for analyzing co-occurrence data based on probabilistic clustering by mixture models. More specifically, we discuss three models which pursue different modeling goals and which differ in the way they define the probabilistic partiti...
