True random number generation based on instrument data
The present disclosure provides computing apparatuses, methods and software for generating random numbers. Data is received from an instrument characterising macromolecules in a sample, the data including measurement event information relating to measurements of individual macromolecules recorded over time. For each measurement event in a sequence of measurement events in the data, an event timing representative of the duration of event or the time passing between consecutive events is determined. This is compared with a comparator value to generate a binary output, and a bit value is determined based on the binary output. Data representative of a random number is generated by assembling a vector of bit values determined from the event timings in sequence. The determined sequence of event timings for the sequence of measurement events represents a source of entropy extracted by the comparison step to generate the random number. |

Disclosed is a structure for implementing a Physically Unclonable Function (PUF)-based random number generator and a method for forming the structure. The structure includes same-type, same-design devices in a semiconductor layer. While values of a performance parameter exhibited by some devices (i.e., first devices) are within a range established based on the design, values of the same performance parameter exhibited by other devices (i.e., second devices) is outside that range. A random distribution of the first and second devices is achieved by including randomly patterned dopant implant regions in the semiconductor layer. Each first device is separated from the dopant implant regions such that its performance parameter value is within the range and each second device has a junction with dopant implant region(s) such that its performance parameter value is outside the range or vice versa. A random number generator can be operably connected to the devices to generate a PUF-based random number. |

At least one execution pipeline receives first and second load operations, detects a condition in which the first load generates a need for an architectural exception, the second load misses in the cache memory, and the second load is newer in program order than the first load, and prevents state of the cache memory from being affected by the miss of the second load by inhibiting the fill request generation logic from generating a fill request for the second load or by canceling the fill request for the second load if the fill request generation logic has already generated the fill request for the second load. |

Re-identification of agents using image analysis and machine learning
As agents move about a materials handling facility, tracklets representative of the position of each agent are maintained along with a confidence score indicating a confidence that the position of the agent is known. If the confidence score falls below a threshold level, image data of the agent associated with the low confidence score is obtained and processed to generate one or more embedding vectors representative of the agent at a current position. Those embedding vectors are then compared with embedding vectors of other candidate agents to determine a set of embedding vectors having a highest similarity. The candidate agent represented by the set of embedding vectors having the highest similarity score is determined to be the agent and the position of that candidate agent is updated to the current position, thereby re-identifying the agent. |

Efficient and scalable time-series data storage and retrieval over a network
Time-series columnar-based information is received and indexed in a compute infrastructure for cost-effective cloud-based object storage.

Such usage data can efficiently facilitate identifying relevance even with an absence of negative feedback. Using the set of distribution parameters, a corresponding distribution is generated. Each distribution can then be sampled to identify a relevance score for each candidate metric indicating an extent of relevance of the corresponding metric. Based on the relevance scores for each candidate metric, a candidate metric is designated as relevant to the user. |

Conditional response fulfillment cache for locally responding to automated assistant inputs
Implementations set forth herein relate to conditionally caching responses to automated assistant queries according to certain contextual data that may be associated with each automated assistant query. Each query can be identified based on historical interactions between a user and an automated assistant, and—depending on the query, fulfillment data can be cached according to certain contextual data that influences the query response. Depending on how the contextual data changes, a cached response stored at a client device can be discarded and/or replaced with an updated cached response. For example, a query that users commonly ask prior to leaving for work can have a corresponding assistant response that depends on features of an environment of the users. This unique assistant response can be cached, before the users provide the query, to minimize latency that can occur when network or processing bandwidth is unpredictable. |

Code integration with time-variant test failure detection
Software code is tested to determine relative performance of the software code. Successfully executing a test may be used to flag problems in a code repository to be corrected or criteria for accepting code for acceptance to the repository.
