Novel and advantageous insulator discs with embedded resonator coils are provided. By linking the insulator discs in a series using an appropriate mechanical mechanism, the insulator discs form an insulator or insulator string for a high power transmission line system. The resonator coils embedded inside the insulator discs therefore form a series of relay resonators that can be used for wireless power transfer through the principle of near-field magnetic coupling and resonance. The insulator string can provide the simultaneous functions of voltage insulation and wireless power transfer over the length of the string. Applications include, but not limited to, wireless power transfer in a high-voltage environment such as that encountered in high-voltage power transmission line systems.

A fast algorithm is used to study the transient behavior due to the step-like pulse. This algorithm consists of two parts: The algorithm I reduces the computational complexity to T^(0)N^(3 )for large systems as long as T

A highly rigid tetradentate ligand is combined with a gold(III) ion as a thermally stable tetradentate gold(III) complex. The tetradentate gold(III) complex is a tetradentate gold(III) compound that can be used as a light-emitting material which can be used for fabricated of light-emitting devices such as an organic light-emitting diode (OLED). The tetradentate gold(III) compound can be deposited as a layer or a component of a layer using a solution-process or a vacuum deposition process. The luminescent tetradentate gold(III) compounds are robust and can provide electroluminescence (EL) with a high efficiency and brightness.

Methods of diagnosis and/or prognosis of malignant disease from pleural effusion samples are disclosed. The methods typically include determining the normalized intensity of one or more biomarkers, such as acetone and 3-hydroxybutyate, in pleural effusion samples using nuclear magnetic resonance (NMR), such as proton NMR (^(1)H-NMR) spectroscopy. Reference values for malignant disease diagnosis using the disclosed biomarkers are provided. Reference values for prognosis of median survival time based on the disclosed biomarkers are also provided.

In one embodiment, provided are a new class of diarylethene-containing photochromic compounds with the incorporation of silicon-or phosphorus-containing heterocycles into the ethene part of the diarylethene backbone that has been shown to be capable of displaying tunable, robust and thermally stable photochromic properties.

A correlated colour temperature control system (1) for a LED lighting system (2) having at least two LED sources (3, 4) with different correlated colour temperatures. The LED lighting system (2) has a combined correlated colour temperature resulting from the combination of the different correlated colour temperatures of the at least two LED sources (3, 4), and a combined luminous flux resulting from the combination of the luminous fluxes of the at least two LED sources (3, 4), with each LED source being supplied with a supply current. The correlated colour temperature control system (1) comprises a controller (5) to independently control one or both of the duty cycle and amplitude of each supply current, the duty cycle or amplitude of each supply current being varied by the controller in a non-linear relationship with the duty cycle or amplitude of at least one other of the supply currents, to generate a desired combined correlated colour temperature for the LED lighting system (2) at a desired combined luminous flux for the LED lighting system (3, 4). An associated method is also provided.

Atmospheric pressure megavolt electrostatic field ionization desorption (APME-FID) method generates ions directly from the surface of sample (2) connected to a high electrical voltage generator (1) at megavolt conditions. Megavolt electrostatic potential is generated and gradually accumulated directly on the sample (2) surface by a Van de Graaff generator without causing damage to the sample (2). Therefore, when coupled with mass spectrometric system, the APME-FID-MS method enables direct detection of analytes on the surface of samples in different sizes and diverse types.
