Abstract: Technologies are generally described to form a waveguide in a polymer multilayer comprising a first and second polymer layer. The waveguide may be formed by directing light beams toward the polymer multilayer to form first and second cladding regions in the polymer multilayer, where the first and second cladding regions comprise a mixture of the first and second polymer layers. The first and second cladding regions may define a third cladding region and a waveguide core therebetween, where the third cladding region comprises a portion of the second polymer layer, and the waveguide core comprises a portion of the first polymer layer. In some examples, the polymer multilayer may be formed on a substrate such that the waveguide is formed on the substrate.

Abstract: A cache coherence mechanism may comprise a bit-to-cache map for processor cores operable up to a maximum frequency for cores of a multicore processor. Entries in a cache coherence directory may include a bit field identifying cores operable at or near the maximum frequency that share a memory block corresponding to the entry. An additional field may indicate sharing by cores operating at lower frequencies. The additional field may be indicative of the bit-field corresponding to a bit-to-cache map representative of cores other than those operating at or near the maximum frequency.

A system includes an radio-frequency identification (RFID) tag composed of a patterned metal. The patterned metal is configured to absorb a volatile chemical. The RFID tag includes a non-volatile memory configured to store identification data. The RFID tag also includes a receiver that receives a signal at a frequency in a frequency range.

The strength of the transmitted identification data is based upon an amount of the absorbed volatile chemical.

Abstract: Technologies are generally described for establishing secure communications to manage components of a control system. In some examples, upon receiving a request from a component to join a cluster of components, a class and instance of the component may be verified to authorize the component. A command to be transmitted from the component to another component of the cluster may be marked with a signature, where restrictions may be placed on a type of command that a particular class of component may transmit to one or more other classes of components. Based on the signature, a secure communication path between the components may be established by creating an encrypted virtual private network (VPN). The command may then be transmitted from the component to the other component through the secure communication path.

Abstract: Technologies are generally described for systems, devices and methods effective to execute a first computing task by a processor of a data center. In some examples, the first computing task may be executed using an instruction set extension. Execution of the first computing task using the instruction set extension may require a first number of clock cycles. In other examples, execution of the first computing task without using the instruction set extension may require a second number of clock cycles. In some examples, a savings value may be determined. The savings value may represent a difference between the first number of clock cycles and the second number of clock cycles. An amount of processing time may be allocated on the processor to a second computing task. The amount of processing time may be based on the savings value. The second computing task may be different from the first computing task.

The membrane may also include a gas sorbent that may be configured to contact a surface of the graphene layer. The gas sorbent may be configured to direct at least one gas adsorbed at the gas sorbent into the nanoscale pores. The nanoscale pores may have a diameter that selectively facilitates passage of a first gas compared to a second gas to separate the first gas from a fluid mixture of the two gases. The gas sorbent may increase the surface concentration of the first gas at the graphene layer. Such membranes may exhibit improved properties compared to conventional graphene and polymeric membranes for gas separations, e.g., greater selectivity, greater gas permeation rates, or the like.
