Agents: An Open-source Framework for Autonomous Language Agents

Recent advances on large language models (LLMs) enable researchers and developers to build autonomous language agents that can automatically solve various tasks and interact with environments, humans, and other agents using natural language interfaces. We consider language agents as a promising direction towards artificial general intelligence and release Agents, an open-source library with the goal of opening up these advances to a wider non-specialist audience. Agents is carefully engineered to support important features including planning, memory, tool usage, multi-agent communication, and fine-grained symbolic control. Agents is user-friendly as it enables non-specialists to build, customize, test, tune, and deploy state-of-the-art autonomous language agents without much coding. The library is also research-friendly as its modularized design makes it easily extensible for researchers. Agents is available at https://github.com/aiwaves-cn/agents.Comment: Code available at https://github.com/aiwaves-cn/agent

开放边界的经济社会学

International audienceCet ouvrage est le fruit de coopérations longues entre sociologues français et sociologues chinois depuis 2008 dans le champ de la sociologie économique dans la cadre du Laboratoire International Associé (LIA) CNRS-ENS Lyon/Académie des Sciences Sociales de Chine Post-Western Sociology in Europe and in China. Ces chercheurs montrent que si, dans un premier temps, les influences de la sociologie américaine ont largement joué sur la définition des frontières des nouvelles sociologies économiques française et chinoise, ces sociologies sectorielles se sont progressivement autonomisées dans leurs contextes sociétaux spécifiques et des savoirs sociologiques propres se sont élaborés. Les processus de fabrication des savoirs en sociologie économique en Chine et en France varient selon les trajectoires scientifiques, une diversité de postures et de sciences de terrain définit des espaces propres et des espaces partagés à partir des pratiques de recherche. Sociologues français et chinois partagent des intérêts spécifiques et ont mené des recherches sur des thématiques proches.本书旨在从若干侧面展现中法学者在经济社会学研究中的开放性。这种开放性不仅体现在研究领域方面打破了社会学和经济学原有的分界，而且体现在研究者们在理论和方法方面不囿于原有学科惯例的尝试中。本书分为两大部分。第一部分讨论学科边界与方法；第二部分是有理论思考的经验研究，涉及生产组织、各类市场、产业集群、社会组织、企业家、技术扩散、迁移、政府行为等。研究者们力求从资料中提炼出更为一般的要素，从而超越地域，在更具普遍性的层面，和学术界开展对话

Experimental Study on the Temperature Field of Cold Region Tunnel under Various Groundwater Seepage Velocities

Groundwater seepage significantly affects the temperature field of a cold region tunnel. Laboratory model tests are carried out to evaluate its effects, yielding four main results. First, groundwater seepage can increase tunnel air temperature and decrease the thickness and length of the tunnel insulation layer. Second, groundwater seepage and tunnel ventilation exert a coupling effect on the surrounding rock temperature. This effect is related to the surrounding rock depth. Third, the influence of the groundwater seepage velocity on the temperature of the interface between the lining and surrounding rock demonstrates a spatial difference, and the groundwater seepage leads to an uneven temperature distribution at the interface between the lining and surrounding rock. Furthermore, under groundwater seepage, the shape and size of the tunnel cross section have significant effects on the interface temperature. Fourth, the cold region tunnel has an antifreezing capability that is mainly related to the frost heaving of the surrounding rock and the groundwater seepage velocity. This capability should be fully utilized in the design of cold region tunnels. The experimental data presented can be used to verify the reliability of the theoretical calculation model for tunnel temperatures in cold regions

Simulating large-scale p2p systems with the wids toolkit

Current simulation technologies support at most hundreds of thousands of nodes, and fall short on the emerging large-scale networking systems that usually involve millions of nodes. We meet this challenge with our distributed simulation engine that is able to run millions of instances and is tested with a production P2P protocol, using commodity PC clusters. This simulation engine is part of the WiDS toolkit, which takes a holistic approach to the research and development of distributed systems. We also propose a critical optimization, called Slow Message Relaxation (SMR), to trade simulation accuracy for performance. By taking advantage of the fact that distributed protocols are resilient to network fluctuation, SMR executes events in a logical time window much wider than the conventional lookahead scheme allows. We analyze and bound the potential effect of the distortion on application logic and other general metrics. Our experiments demonstrate that the simulation engine is able to achieve order of a magnitude speedup with statistically accurate simulation results. 1

Investigation of the Thermal Performance of Energy Tunnel Equipped with the Insulation Layer Considering Ventilation and Groundwater Seepage

The insulation layer is usually installed in the tunnel structure, whereas the influence of the insulation layer on the thermal behavior of energy tunnel ground heat exchangers (GHEs) is rarely investigated. The model tests were performed in this study to evaluate the heat transfer potential of the energy tunnel with the insulation layer under ventilation and groundwater seepage. The results can be obtained as follows: first, the fluctuations of air temperature and surrounding rock temperature at different locations are relevant to insulation layer, ventilation, and groundwater seepage. Second, the reduction effect of ventilation on the interface temperature of tunnel lining and surrounding rock is alleviated when using an insulation layer, and the interface temperature at upstream section of groundwater seepage is more easily affected by the energy tunnel GHEs. Third, the variation range of ground temperature is wider at the downstream section of groundwater flow. Moreover, the heat exchange rates of tunnel without the insulation layer improve by 5.82% and 6.45% with increasing wind speed at two groundwater flow velocities of 1×10−4 and 5×10−4 m/s, and there are only 2.03% and 0.77% enhancements of heat exchange rates by ventilation for the tunnel with the insulation layer. However, the thermal performance of the energy tunnel improved by groundwater is less relevant to the existence of the insulation layer. The relevant findings can provide an effective guidance for the following research and design of the energy tunnel
