Abstract: A data processing apparatus comprises a plurality of data storage elements, each configured to store data. Mask storage circuitry stores a mask and processing circuitry executes one or more instructions. A data saver is configured, in response to a transactional start instruction, to select a subset of the data storage elements and to save a backup of the subset of the data storage elements. Mask control circuitry then updates the mask to indicate the subset of the data storage elements selected by the data saver. Finally, a monitor detects write or write attempts made to one of the data storage elements not indicated by the mask. Accordingly, a user need not save all data storage elements (e.g. registers) in a system or specify precisely which data storage elements must be saved in order to perform a transaction.

Abstract: A data processing apparatus and method of data processing are provided, which relate to the operation of a processor which maintains a push call stack in dependence on the data processing instructions executed. The processor is configured to operate in a transactional execution mode when the data processing instructions seek access to a stored data item which is shared with a further processor. When the processor enters its transactional execution mode it stores a copy of the current stack depth indication and thereafter, when operating in its transactional execution mode, further modifications to the call stack are compared to the copy of the stack depth indication stored. If the relative stacking position of the required modification is in a positive stack growth direction with respect to the copy stored, the modification to the call stack is labelled as non-speculative.

Abstract: A nanoscale calcinated silicate film fabricated on a gold substrate for highly effective, matrix-free laser desorption ionization mass spectrometry (LDI-MS) analysis of biomolecules. The calcinated film is prepared by a layer-by-layer (LbL) deposition/calcination process wherein the thickness of the silicate layer and its surface properties are precisely controlled. The film exhibits outstanding efficiency in LDI-MS with extremely low background noise in the low-mass region, allowing for effective analysis of low mass weight samples and detection of large biomolecules including amino acids, peptides and proteins. Additional advantages for the calcinated film include ease of preparation and modification, high reproducibility, low cost and excellent reusability. Experimental parameters that influence LDI on calcinated films have been systemically investigated. Presence of citric acid in the sample significantly enhances LDI performance by facilitating protonation of the analyte and reducing fragmentation.

Abstract: Multi-media content for inclusion into an SMS (Short Message Service), MMS (Multi-media Message Service), IM (Instant Message) or other message type can be searched, pre-searches, fetched and pre-fetched based upon predictive- and rules-based searching techniques. A system can predict or infer an in-process message, for example, based upon a portion of the inputted text message. Thereafter, in real- or near real-time, content related to the topic of conversation can be retrieved from a local store, remote stores (e.g., servers) or cloud-based sources. The retrieved content can be incorporated into the SMS, MMS, or IM message as appropriate or desired thereby enhancing the messaging experience.
