Abstract: A device for synthesis of macromolecules is disclosed. In one aspect, the device comprises an ion-releaser having a synthesis surface comprising an array of synthesis locations arranged for synthesis of the macromolecules. The ion-releaser also includes an ion-source electrode, which is arranged to contain releasable ions and is arranged to be in contact with each of the synthesis locations of the synthesis surface, thereby release ions to the synthesis locations. The ion-releaser further comprises activating electrodes, which are arranged to be in contact with the ion-source electrode, wherein each one of the activating electrodes is arranged in association with one of the synthesis locations via the ion-source electrode. The ion-releaser is arranged to release at least a portion of the releasable ions from the ion-source electrode to one of the synthesis locations, by activation of the activating electrode associated with the synthesis location.

Abstract: A dispersive optical phased array for two-dimensional scanning is disclosed herein. The array comprises antenna blocks positioned adjacent one another. The antenna blocks comprise a plurality of antennas positioned adjacent one another and a plurality of delay lines to couple a coherent source signal to each of the antennas within the block, each delay line having an optical path length. Each of the antenna blocks acts as a dispersive phased array. The antenna blocks are arranged such that the blocks form a larger phased array where the antennas between the blocks are in phase for a discrete set of wavelengths. All antennas over the dispersive phased array can experience the same phase difference such that the beams of the individual antenna blocks align with one of the diffraction orders of the array of blocks.

Abstract: A method and apparatus are provided for a spectroscopic measurement for determining a lateral recess depth in the sidewall of a microstructure. The structure is formed on a larger substrate with the sidewall in an upright position relative to the substrate, and the recess extends essentially parallel to the substrate. The recess may be an etch depth obtained by etching a first layer relative to two adjacent layers, the layers oriented parallel to the substrate, the etch process progressing inward from the sidewall. An incident energy beam falling on the structure generates a spectroscopic response captured and processed respectively by a detector and a processing unit. The response comprises one or more peaks related to the material or materials of the substrate and the structure. According to the method, a parameter is derived from said one or more peaks, that is representative of the lateral recess depth.

Abstract: A computer-implemented method for exploring, by a table-based parallel reinforcement learning, PRL, algorithm, an unexplored domain comprising a plurality of agents and states, the unexplored domain represented by a state-action space. The method includes the steps performed by one or more of the plurality of agents receiving an assigned partition of the state-action space represented by a table; and executing during a plurality of episodes actions for states within the partition. An action transits a state; and granting to a transited state a reward; and exchanging state-action values with other agents of the plurality of agents in the domain; and updating the table.
