Abstract

The invention provides a cryogenic liquid pump system, having a first end with at least an insulating lid and motor; a second end, wherein the second end is a pump, said pump comprising an impeller; and a gas release plate upstream of the impeller; and a shaft disposed between the first end and the second end, wherein the motor imparts mechanical energy to the pump through the shaft. Also provided is a method for preventing cavitation of a cryogenic liquid in a cryogenic pump, the method having the steps of constantly maintaining pressure on the liquid in the pump and evacuating gas bubbles that form within the pump.

Large language models for transportation research: Methodologies, state of the art, and future opportunities

The rapid rise of large language models (LLMs) is transforming transportation research, with significant advancements emerging between 2023 and 2025, a period marked by the inception and swift growth of adopting and adapting LLMs for various transportation applications. Despite these significant advancements, however, a systematic review and synthesis of the existing literature remains lacking. This paper aims to fill this gap by providing a comprehensive review of the methodologies and applications of LLMs in transportation. We explore key applications, including autonomous driving, travel behavior prediction, and general transportation-related queries, alongside LLM methodologies such as zero- or few-shot learning, prompt engineering, and fine-tuning. From the review, critical research gaps are identified. From the methodological perspective, many of the research limitations can be addressed by integrating LLMs with existing tools and refining LLM architectures. From the application perspective, research opportunities for LLMs to address various transportation challenges are also explored. By synthesizing these findings, this review not only presents the state-of-the-art LLM adoption and adaptation in transportation, but also proposes future research directions as well as insights and recommendations for policymakers and practitioners, paving the way for greater LLM-driven research innovations in transportation in the future.
