Optoelectronic oscillator (OEO) has received growing attentions from researchers in the field of demodulations for optical sensors because its excellent performance combining optics and electronics signal processing. In this article, we present a wideband-tunable OEO angular velocity measurement. The consists two cascaded microwave photonic filters (MPFs), namely, dispersion-induced MPF mainly determining OEO's oscillating frequency two-tap fine selection frequency. With proper control...
Here, we propose the use of carboxyl-functionalized ionic liquid, [Hbet][Tf2N], to separate fission products from spent nuclear fuels. This innovative method allows selective dissolution neutron poisons, lanthanides oxide, as well some with high yield, leaving most UO2 matrix and minor actinides behind in fuel accomplishing recovery a group. Water-saturated [Hbet][Tf2N] can dissolve oxide simulated ratio 100% at 40 °C. However, uranium is almost negligible (<1%) under same conditions. big...
Titanium (Ti) alloys of the β-type are highly attractive metallic materials for biomedical applications due to their low elastic modulus, high corrosion resistance and notable biocompatibility. A new Ti35Nb2Ta3Zr alloy with a Young's modulus approximately 48 GPa was previously fabricated. In present study, biocompatibility this evaluated. an in vitro assay, did not markedly affect adhesion MG63 osteoblast cells, but it increased proliferation, alkaline phosphatase (ALP) activity, calcium...
In this paper, a meta-learning-based underwater acoustic (UWA) orthogonal frequency division multiplexing (OFDM) system is proposed to deal with the environment mismatch in real-world UWA applications, which can effectively drive model from given new relatively small amount of data.

The...
β type titanium alloys have attracted much attention in the biomedical field because they consist of non-cytotoxic elements, show high corrosion resistance, and are biologically compatible. In this study, a novel alloy (Ti35Nb3Zr2Ta) with Young's modulus 48 GPa was fabricated alloy's resistance vitro response were determined.

Abstract Uranium tetraboride ( UB 4 ) was successfully synthesized by boro/carbothermal reduction of UO 2 with B C and carbon as combined agents under flowing argon. The effects processing temperature mole ratios starting materials on phase evolution were studied. XRD results demonstrated that obtained 3.75 mol% in excess based the /B C/C molar 1:1:1 at 1500°C. SEM observation revealed submicrometer‐sized quasi‐spherical particles cemented together to be an aggregate. laser particle size...

Furthermore, cost much lower of
The fibre-optic interferometric hydrophone has been widely used in ocean acoustic applications. There are many different systems use. They can generally be classified as hull mounted, towed, or fixed (bottom mounted and vertical) array systems. Different optical architectures have evolved for each of the areas, which make a good case study on what aspects particular application influence architecture. A novel architecture based PMDI is theoretically experimentally discussed this paper....
