Jais and Jais-chat: Arabic-Centric Foundation and Instruction-Tuned Open Generative Large Language Models

We introduce Jais and Jais-chat, new state-of-the-art Arabic-centric foundation and instruction-tuned open generative large language models (LLMs). The models are based on the GPT-3 decoder-only architecture and are pretrained on a mixture of Arabic and English texts, including source code in various programming languages. With 13 billion parameters, they demonstrate better knowledge and reasoning capabilities in Arabic than any existing open Arabic and multilingual models by a sizable margin, based on extensive evaluation. Moreover, the models are competitive in English compared to English-centric open models of similar size, despite being trained on much less English data. We provide a detailed description of the training, the tuning, the safety alignment, and the evaluation of the models. We release two open versions of the model -- the foundation Jais model, and an instruction-tuned Jais-chat variant -- with the aim of promoting research on Arabic LLMs. Available at https://huggingface.co/inception-mbzuai/jais-13b-chat

Contemplating electromagnetic phenomena in lived experience through somatic meditation

One of the objectives of the undergraduate physics curriculum is for students to become aware of the connections between formal physical principles and personal experience. However, research has shown that awareness of connections between the abstract and the experiential tends to deteriorate, sometimes significantly, following instruction in undergraduate physics courses. Although this phenomenon has been discussed extensively in the literature, few pedagogical interventions have been designed or implemented to address this particular weakness in undergraduate physics instruction. In this work, we show that a contemplative practice consisting of a somatic meditation and a contemplation deepens students' awareness of the connections between formal physical principles and personal experience by deliberately drawing their attention to electromagnetic phenomena in their surroundings. In this process, students also note interdisciplinary connections between electrodynamic principles and chemical and biological systems. We also find that the contemplative practice awakens an intrinsic motivation to understand electromagnetic theory, as well as an appreciation for the somatic, affective, and cognitive benefits of a contemplative practice.

General triple charged black ring solution in supergravity

We present the general black ring solution in $U(1)^{3}$ supergravity in 5 dimensions with three independent dipole and electric charges. This immediately gives the general black ring solution in the minimal 5D supergravity as well.
