摘要:
Embodiments of the disclosure are directed to generating a random number. An embodiment of the disclosure passes a current from a read operation through a magnetic tunnel junction (MTJ) to cause a first magnetization orientation of a free layer to switch to a second magnetization orientation, the switch in magnetization orientation causing a change in a resistance of the MTJ, and periodically samples the resistance of the MTJ to generate a bit value for the random number.
摘要:
A probabilistic programming current is injected into a cluster of bi-stable probabilistic switching elements, the probabilistic programming current having parameters set to result in a less than unity probability of any given bi-stable switching element switching, and a resistance of the cluster of bi-stable switching elements is detected. The probabilistic programming current is injected and the resistance of the cluster state detected until a termination condition is met. Optionally the termination condition is detecting the resistance of the cluster of bi-stable switching elements at a value representing a multi-bit data.

The invention provides a fluidized bed polymerization reactor, including: a column, in which a liquid distributor and a gas distributor above the liquid distributor are arranged, so that the reaction zone being divided into a first zone and a second zone through the gas distributor; and a circulating unit for circulating the gas material originated from the top zone of the column into the bottom zone thereof in a form of gas-liquid mixture. The gas-liquid mixture is undergone a gas-liquid separation in the bottom zone, the gas phase portion obtained being fed to the gas distributor and then into the second zone while the liquid phase portion obtained being entered into the first zone through the liquid distributor, so that the temperature in the first zone is lower than that in the second zone. Therefore, polymer with a molecular weight distributed in a relatively wide range can be obtained. The invention further provides a method for preparing polymer.

摘要:
Certain aspects of the present disclosure relate to a method for processing wireless communications. According to one aspect, a processing unit may receive a plurality of code blocks of a transport block and schedule the plurality of code blocks to be decoded in parallel with a plurality of decoders. Each decoder decodes at least one code block as an independent tasks. The processing unit further collects the decoded information bits from the plurality of decoders and forwards the collected decoded information bits for further processing. In one aspect, the processing unit includes an output agent to temporarily store the decoded information bits while waiting for all code blocks of the transport block to be decoded.
