Abstract: Software development kit (SDK) class tree structures of malicious SDKs are created, with each node of the SDK class tree structures representing a class of a corresponding malicious SDK. An app class tree structure of a mobile app is also created, with each node of the app class tree structure representing a class of the mobile app. To determine if the mobile app has been created (e.g., repackaged or originally created) using at least one of the malicious SDKs, the app class tree structure is compared against the SDK class tree structures to find an SDK class tree structure that matches the app class tree structure. For confirmation, the similarity of classes of the app class tree structure relative to classes of the SDK class tree structure can be determined.

Abstract: The present disclosure relates to a method of electrically aging a PMOS thin film transistor. The method includes applying a first voltage Vg with an amplitude of A volts to a gate of the PMOS thin film transistor; applying a second voltage Vs with an amplitude of (A-40) to (A-8) volts to a source of the PMOS thin film transistor; and applying a third voltage Vd with an amplitude of (A-80) to (A-16) volts to a drain of the PMOS thin film transistor. Application of the first voltage Vg, the second voltage Vs and the third voltage Vd is maintained for a predetermined time period, and Vd?Vs<0. In this way, reduction of a leakage current of the PMOS thin film transistor is achieved without changing a structural design of the thin film transistor.

Abstract: Original program code of an app of a mobile operating system is protected by splitting the original program code into several program code segments and encrypting the program code segments. The encrypted program code segments are received in separate files in a mobile computing device, where the encrypted program code segments are loaded in memory of the mobile computing device. The encrypted program code segments are decrypted, and the resulting decrypted program code segments are stored in non-contiguous blocks of memory. The decrypted program code segments are parsed for loading and execution in the mobile computing device, such as by a Dalvik process virtual machine of an ANDROID operating system of the mobile computing device.

Abstract: Aerial vehicles are provided with one or more transformable arms (110, 310, 410, 510, 910). The one or more transformable arms (110, 310, 410, 510, 910) may support one or more propulsion units, and transform between a flight configuration where the propulsion units of the arms effect flight of the aerial vehicle, and a landing configuration, wherein the transformable arms (110, 310, 410, 510, 910) are used as a landing support that bears weight of the aerial vehicle when the aerial vehicle is not in flight.
