    Historical foreword: Jean Dalibard, the magneto-optical trap, and the ascent of physics with cold atomic gases by Phillips, William

    Published 2024-02-01
    “…I present my personal perspective on the importance of the invention by Jean Dalibard of the magneto-optical trap (MOT), which has for many years been the “workhorse” of the field of laser cooling and cold atomic gases. I recount some of the history related to the MOT and argue that its invention enabled cold atomic gases to become the dominant part of Atomic, Molecular, and Optical (AMO) physics that it is today.…”

    Feature engineering descriptors, transforms, and machine learning for grain boundaries and variable-sized atom clusters by C. Braxton Owens, Nithin Mathew, Tyce W. Olaveson, Jacob P. Tavenner, Edward M. Kober, Garritt J. Tucker, Gus L. W. Hart, Eric R. Homer

    Published 2025-01-01
    “…Abstract Obtaining microscopic structure-property relationships for grain boundaries is challenging due to their complex atomic structures. Recent efforts use machine learning to derive these relationships, but the way the atomic grain boundary structure is represented can have a significant impact on the predictions. …”

    Atomic Mineral Characteristics of Indonesian Osteoporosis by High-Resolution Inductively Coupled Plasma Mass Spectrometry by Zairin Noor, Sutiman Bambang Sumitro, Mohammad Hidayat, Agus Hadian Rahim, Akhmad Sabarudin, Tomonari Umemura

    Published 2012-01-01
    “…Conversely, concentrations of Na, Mg, P, K, Ca, Cr, Pd, Ag, Mn, Fe, Cu, Zn, Rb, Sr, Pb, and Se are lower in osteoporosis than in normal bones. Among these atoms, known to have important roles in bone structure, we found involvement of atomic mineral and calcium which are considerable to contribute to osteoporotic phenomena.…”
