Abstract: An integrated-circuit chip comprises a plurality of scan flip-flops and a retention cell. The chip is configured to have a scan-capture mode, in which the plurality of scan flip-flops and the retention cell are connected to respective functional circuitry of the integrated-circuit chip, and to have a scan-shift mode, in which the plurality of scan flip-flops and the retention cell are connected so as to form a scan chain for use during scan-chain testing of the integrated-circuit chip. The chip further comprises on-chip test circuitry arranged to generate and output a save signal, a clock signal, and a restore signal to the retention cell, for testing the retention cell during scan-chain testing of the integrated-circuit chip.

Abstract: Synthetic transcriptions factors for modulation of frataxin expression and methods of use are described herein.

Abstract: A circuit portion is disclosed comprising an operational input and a scan input; a logic portion comprising at least one input and at least one output; and a first scan latch comprising at least one input and at least one output. The circuit portion is arranged to operate in an operational mode in which the operational input is connected to an input of the logic portion and the logic portion operates as an asynchronous latch to generate an operational output signal at an output of the logic portion; and a scan mode in which the logic portion operates as part of a second scan latch, and the first scan latch and the second scan latch form a synchronous flip-flop comprising an input connected to the scan input and arranged to generate a scan output signal.

Abstract: A system and methods are disclosed for treating cooling fluid in a continuous metal casting process having a spray chamber. In some embodiments, the system includes a first compartment with an intermittently operable outlet (e.g., valve) with an open state and a closed state, for removing particulate matter, and a second compartment that receives particle-free fluid from the first compartment. The first compartment may be tapered, conical, funnel, pyramidal shape or otherwise narrowed shape to facilitate settling of the particles. One or more sensors measure at least one property of the particle-free fluid to determine the opened or closed state of the outlet and to adjust chemical additives for the cooling fluid. In some embodiments, the system and methods reduce corrosion in spray chambers.
