Abstract: Stable nanoemulsions of a terpene-rich cannabidiol by-product (TP) and/or its distillate (DTP) can be used to effectively make pesticides, herbicides, and other bioactive products. A terpene-rich by-product (TP) can be provided, suitably by isolation from a commercial cannabidiol production process. The enriched terpene distillate (DTP) can be obtained from steam distillation of some or all of the TP. The TP and/or DTP can be combined with a surfactant to form an emulsion, which can then be sonicated to form the stable nanoemulsion. It has been discovered that the formulation of stable nanoemulsions using the terpene by-products as the lipophilic phase can effectively deliver desired levels of bioactivity while overcoming or mitigating the known drawbacks of high lipophilicity, high volatility, and propensity to thermal and oxidative degradation, all of which can lead to reduced efficacy.

Abstract: Provided is an efficient approach to establish a foundational video-text model for tasks including open-vocabulary video classification, text-to-video retrieval, video captioning and video question-answering. Some example implementations include a model which can be referred to as VideoCoCa. Example implementations reuse a pretrained image-text contrastive captioner (CoCa) model and adapt it to video-text tasks with little or minimal extra training. While previous works adapt image-text models with various cross-frame fusion modules (for example, cross-frame attention layer or perceiver resampler) and finetune the modified architecture on video-text data, aspects of the present disclosure leverage findings that the generative attentional pooling and contrastive attentional pooling layers in the image-text CoCa design are instantly adaptable to “flattened frame embeddings”, yielding a strong zero-shot transfer baseline for many video-text tasks.
