Abstract: Logic circuitry packages for association with replaceable print apparatus components are disclosed herein. An example logic circuitry package includes a timer and a serial data bus interface including a data contact and a clock contact, the serial data bus interface to interface with a serial data bus of a printer. The example logic circuitry package also includes logic circuitry to, in response to a first command sent to the logic circuitry package via the serial data bus of the printer: initiate a low voltage on the data contact; wait for a time period tracked by the timer to expire, without reference to a clock signal at the clock contact from the serial data bus; and upon expiration of the time period, cause the data contact to assume a second voltage different than the low voltage. The first command specifies a duration of the time period and the example logic circuitry is to maintain the low voltage on the data contact based on the duration of the time period.

Abstract: An enzymatic purification method involves the introduction of a sample comprising a target analyte and amino acids into a porous matrix of a reaction chamber. The reaction chamber includes first pores and second pores. The first pores contain polypeptide synthesis enzymes that react with the amino acids to form polypeptides. First pores having a first size to be accessible by amino acids but inaccessible by the subsequently formed polypeptides. The second pores have a second size greater than the first size, are in contact with the first pores and form a series extending from within the reaction chamber to a waste chamber. The formed polypeptides are migrated through the series of second pores to the waste chamber. The target analyte of the sample is extracted from the reaction chamber.

Abstract: An imaging device for a passive e-paper display includes an erasing head to emit ions in a first polarity followed by an opposite second polarity after a first time period. The passive e-paper display is mountable on a support in a spaced apart relationship relative to the erasing head and by which the emitted ions are receivable onto substantially the entire surface of the passive e-paper display. Relative movement occurs between the support and the erasing head at least some of the time during the emission of ions from the erasing head.

Abstract: Example embodiments relate to creating test templates based on steps in existing tests. In example embodiments, a testing computing device may select an existing test from multiple existing tests. Each existing test of the multiple existing tests may include a set of distinct steps. The testing computing device may determine a sub-sequence related to the selected existing test. The sub-sequence may be based on a subset of the distinct steps included in the selected existing test. The testing computing device may determine that the distinct steps in the subset occur in a number of existing tests from the multiple existing tests, and may generate a test template using the sub-sequence. The test template may include the distinct steps in the subset.

Abstract: Systems, methods, and machine readable and executable instructions are provided for collaborative filtering. Collaborative filtering includes representing users and objects by rows and columns in an ordinal ratings matrix having a particular dimensional space. Values in the ordinal ratings matrix are weighted with a weight matrix having the particular dimensional space. The weight matrix is hashed into a lower dimensional space by one of row and column by multiplying a projection matrix by the weight matrix. The ordinal ratings matrix is hashed into a lower dimensional space by multiplying the projection matrix by an element-wise product of the weight matrix and the ordinal ratings matrix to form a reduced ratings matrix, and element-wise dividing the reduced ratings matrix by the hashed weight matrix. The hashed ordinal ratings matrix and the hashed weight matrix are low-rank approximated by alternating least squares.
