Abstract: Methods are disclosed for determining the minimal residual cancer status of an individual utilizing assays that detect cancer associated genetic variation in extracellular DNA. The disclosed methods provide for personalized cancer detection based on the genetic profile of solid cancer tissue of an individual under study. The disclosed methods further provide for noise reduction in the sequencing of extracellular DNA and reduced false positive rates in minimal residual cancer status determination.

Abstract: A method and device for hiding an application (APP) icon. The method includes monitoring, in a desktop interface, a hiding operation on a first APP icon by a second APP icon, the second APP icon being an APP icon of an installed APP; and hiding the first APP icon in the desktop interface.

Abstract: An over-current protection device comprises two metal foils, a positive temperature coefficient (PTC) material layer and a packaging material layer. The PTC material layer is sandwiched between the two metal foils and has a volume resistivity below 0.1 ?-cm. The PTC material layer includes (i) plural crystalline polymers having at least one crystalline polymer with a melting point less than 115° C.; (ii) an electrically conductive nickel filler having a volume resistivity less than 500 ??-cm; and (iii) a non-conductive metal nitride filler. The electrically conductive nickel filler and non-conductive metal nitride filler are dispersed in the crystalline polymer. The packaging material layer which encapsulates the chip is essentially comprised of the PTC layer and the two metal foils. The packaging material layer is formed by reacting epoxy resin with a hardener having amide functional group.

Abstract: A receptacle capable of warning overloading includes a receptacle main body and a protect device. The receptacle main body transmits a power source to an electric product while a plug of said electric product being inserted to the receptacle main body. The protect device is attached to the receptacle main body. It is characterized in that the protect device further comprises a detect circuit for detecting an amperage, and a warning component for receiving a signal coming from said detect circuit and converting the signal to a warning sound, a warning flash light or a numerical value. Thus, when the output end of the receptacle has an abnormal current overload, the user is notified to be aware of the problem of overloading.

Abstract: A cool cathode tube control circuit for being connected to a lighting device and a plurality of lamp tubes. The cool cathode tube control device includes a regulator control circuit for controlling a lighting device to provide a steady high voltage power source. A lighting control circuit serves for controlling the lighting device so as to drive a plurality of lamp tubes and adjusting the illuminations of the lamp tubes. An abnormality detecting circuit is connected to the lighting device for sensing abnormal signals. A control logic circuit is electrically connected to the regulator control circuit, lighting control circuit and abnormality detecting circuit for receiving and processing input signals from the abnormality detecting circuit so as to generate logic digital signals to be transferred to the regulator control circuit and the lighting control circuit. Thereby, the lighting device is driven so that the plurality of lamp tubes are actuated synchronously and have the same illumination.
