Can algorithms create a pop-music hit?

This week's Question: Sony Computer Science Laboratory (CSL) in Paris is developing a system of algorithms which can create songs that cater to the user's taste, based on styles adapted from existing music. Starting with a sheet-music database of more than 13,000 existing songs, users choose several titles with the sound or feel that they would like the new song to incorporate.

New GASOMETER Design Uses Active Accommodation Offering Significant Improvements Vs. Liquid-sealed Methods

Active Accommodation means using a precision controlled and driven cylinder/piston assembly to collect and measure gas sample volumes without requiring energy to be extracted from the process that generates the gas. The mechanism uses lubricated O-Rings to seal the measuring chamber unlike classical Wet Test Meters that require a water or oil bath to produce an isolation seal.

Entry-Level PXI/PXIe Platforms

ADLINK Technology (San Jose, CA) announced new entry-level PXI and PXI Express (PXIe) platforms for PXI testing system startup users. PXES-2301 is an all-hybrid, 6-slot compact PXIe chassis with system bandwidth up to 8 GB/s. PXIe-3935 and PXI-3930 are embedded controllers with Intel® Celeron® 2000E 2.2GHz processors, delivering up to 50% increase in computing power and as much as eight times the bandwidth of available market offerings. ADLINK's PXIe-3935 and PXI-3930 significantly reduce maintenance burdens with easily replaceable battery and upgradable storage and SODIMM modules. Backup BIOS also eases recovery in the event of a main BIOS crash.Click here to learn more

Scientists Find Twisting 3-D Electron Raceway in Nanoscale Crystal Slices

A scanning electron microscope image shows triangular (red) and rectangular (blue) samples of a semimetal crystal known as cadmium arsenide. The rectangular sample is about 0.8 microns (thousandths of a millimeter) thick, 3.2 microns tall and 5 microns long. The design of the triangular samples proved useful in mapping out the strange electron orbits exhibited by this material when exposed to a magnetic field. (Credit: Nature, 10.1038/nature18276) Researchers have created an exotic 3-D racetrack for electrons in ultrathin slices of a nanomaterial they fabricated at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). The international team of scientists from Berkeley Lab, UC Berkeley, and Germany observed, for the first time, a unique behavior in which electrons rotate around one surface, then through the bulk of the material to its opposite surface and back.

Complex Materials Can Self-Organize Into Circuits

An ORNL study found that complex oxide materials can self-organize into electrical circuits, which creates the possibility for new types of computer chips. (Credit: ORNL) Researchers studying the behavior of nanoscale materials at the Department of Energy’s Oak Ridge National Laboratory have uncovered remarkable behavior that could advance microprocessors beyond today’s silicon-based chips. The study shows that a single crystal complex oxide material, when confined to micro- and nanoscales, can act like a multi-component electrical circuit. This behavior stems from an unusual feature of certain complex oxides called phase separation, in which tiny regions in the material exhibit vastly different electronic and magnetic properties. It means individual nanoscale regions in complex oxide materials can behave as self-organized circuit elements, which could support new multifunctional types of computing architectures.
