Abstract: Systems and methods for semantic temporal segmentation based on topic recognition are disclosed. Text classification and segmentation may be used to index media content for subsequent searches. The method may include using a text classification model to semantically analyze sentences in a text file (such as a transcript) to determine topics with which sentences are associated. The output of the text classification model may be provided to a text segmentation model to enable more-accurate identification of text segments (e.g., paragraphs) within the text file. In some examples, the output of a text segmentation model is provided to a text classification model to enable the text classification model to perform more-accurate classification based on text segments rather than (or in addition to) performing classification on single sentences. The classification of the text segments may be used to assign labels to the text segments to enable subsequent searches based on the labels.

Abstract: This document discloses techniques, apparatuses, and systems for secure pseudo-random number generator (PRNG) reseeding. Integrated circuits (ICs) may use PRNGs to enable cryptographic processes that can protect an IC or electronic device against malicious attacks. Generally, an IC (e.g., a security circuit) may seed or reseed a PRNG with entropy useful to generate pseudo-random numbers or bits. In generating entropy, however, operation of the IC may change and result in circuit characteristics that allow attackers to determine when the IC operates on entropy-related secret information. In this way, attackers may identify moments when attacks have a higher chance of revealing the secret information. In aspects of secure PRNG reseeding, security circuitry may operate circuit elements to limit an association between circuit operations related to entropy generation and observable circuit characteristics.

Abstract: The liquid soil treatments disclosed herein contain choline in amounts effective to prevent turf browning while complimenting the effects of a soil wetting agent on water movement. More specifically, the inclusion of certain amounts of choline with a soil wetting agent improved turf quality, turf color, photochemical efficiency, leaf chlorophyll content, leaf proline content, root surface area, root diameter, and root volume without significantly impacting the water content of the soil. Further, choline was demonstrated to enhance water penetration of a hydrophobic soil, absent of combination with a known soil wetting agent.
