Times Cited Count：0Amino acids are essential for protein synthesis and metabolic processes in support of homeostatic balance and healthy body functions. This study quantitatively investigates eccrine sweat as a significant channel for loss of amino acids during exercise, to improve an understanding of amino acid turnover and to provide feedback to users on the need for supplement intake. The measurement platform consists of a soft, skin-interfaced microfluidic system for real-time analysis of amino acid content in eccrine sweat. This system relies on integrated fluorometric assays and smartphone-based imaging techniques for quantitative analysis.

Times Cited Count：12 Percentile：80.32(Chemistry, Multidisciplinary)This paper presents a set of findings that enhances the performance of these systems through the use of microfluidic networks, integrated valves and microscale optical cuvettes formed by three-dimensional printing in hard/soft hybrid materials systems, for accurate spectroscopic and fluorometric assays. Field studies demonstrate the capability of these microcuvette systems to evaluate the concentrations of copper, chloride, and glucose in sweat, along with the sweat pH, with laboratory grade accuracy and sensitivity.

Systematic benchtop testing and on-body field studies on human subjects exercising in a gym environment highlight the key multifunctional features of this platform in tracking the biochemical correlates of physical stress.

Times Cited Count：90 Percentile：93.96(Chemistry, Multidisciplinary)Excretion of sweat from eccrine glands is a dynamic physiological process that varies with body position, activity level, and health status. Information content embodied in sweat rate and chemistry can be used to assess health status and athletic performance. This paper presents a thin, miniaturized, skin-interfaced microfluidic technology that includes a reusable, battery-free electronics module for measuring sweat conductivity and rate in real-time using wireless power from and data communication with capabilities in near field communications (NFC). Systematic studies of these combined microfluidic/electronic systems, accurate correlations of measurements performed with them to those of laboratory standard instrumentation, and field tests on human subjects establish the key operational features and their utility in sweat analytics.

The entry distribution method, which can determine the excitation energy at which fission starts to dominate the decay process, was applied to No. The fission barrier of No was found to be 6.6 MeV at zero spin, indicating that the No is strongly stabilized by the nuclear shell effects.

Times Cited Count：40 Percentile：90.74(Physics, Nuclear)The neutron-rich isotope Ni was produced by multi-nucleon transfer reactions of Zn in the Argonne National Laboratory, and an in-beam 
-ray experiment were performed using the GRETINA array. The 
and 
levels of Ni were observed for the first time. Those levels are regarded as large deformed states associated with proton excitation from the 
orbit because they cannot be reproduced by a shell-model calculation assuming a small valence space without . A theoretical analysis based on the Monte Carlo shell model published in 2014 indicates that those levels corresponds to a prolate deformed band. The present result demonstrates the occurrence of shape coexistence in neutron-rich Ni isotopes other than a known case of 
Ni, and confirms the predictive power of the Monte Carlo shell-model calculation.

Times Cited Count：34 Percentile：82.09(Physics, Multidisciplinary)Fission barrier heights of a shell-stabilized superheavy nucleus No have been determined as a function of spin up to 19
through the measured distribution of entry points of deexcitations in the excitation energy vs. spin plane. The fission barrier height of No was determined to be 6.0 MeV at spin 15, and 6.6 MeV at spin 0 by extrapolation. This demonstrates that the shell effect actually enlarges the fission barrier in such heavy nuclei and keeps the barrier high even at high spin.

Times Cited Count：3 Percentile：68.16(Physics, Nuclear)Fission barrier heights of No have been determined through the entry distribution method. The entry distribution is the initial distribution of excitation energy and spin from which the deexcitation starts in the fusion-evaporation reaction. The initial distribution is extracted from measured -ray multiplicity and total -ray energy. This paper describes the details of the entry distribution method, and reports the first determination of the fission barrier heights of No, which is the heaviest nucleus whose fission barrier has been measured.
