This paper introduces two important advances in recently reported classes of soft, skin-interfaced microfluidic systems for sweat capture and analysis: (1) a simple, broadly applicable means for collection of sweat that bypasses requirements for physical/mental exertion or pharmacological stimulation and (2) a set of enzymatic chemistries and colorimetric readout approaches for determining the concentrations of creatinine and urea in sweat, across physiologically relevant ranges. The results allow for routine, non-pharmacological capture of sweat across patient populations, such as infants and the elderly, that cannot be expected to sweat through exercise, and they create potential opportunities in the use of sweat for kidney disease screening/monitoring.

We have developed a new setup to measure prompt fission $$gamma$$-ray spectra in neutron induced fission up to energies sufficient to reveal the structure associated with giant dipole resonances of fission fragments. The setup consists of multi-wire proportional counters, to detect both fission fragments in coincidence, and two large volume (101.6 mm in diameter and 127.0 mm in length) LaBr$$_{3}$$(Ce) scintillators, to measure the $$gamma$$-rays. The setup was used to obtain the prompt fission $$gamma$$-ray spectrum for thermal neutron induced fission of $$^{235}$$U at the PF1B cold-neutron beam facility of the Institut Laue-Langevin, Grenoble, France. We have successfully measured the $$gamma$$-ray spectrum up to energies of about 20 MeV, what extends the currently known $$gamma$$-ray spectrum limit to higher energies by approximately a factor of two.

The measurement of the prompt fission $$gamma$$-ray spectrum (PFGS) is quite important to study the de-excitation process of neutron-rich fission fragments as well as to generate data required to design a generation-IV reactors. The PFGS measured for spontaneous fission of $$^{252}$$Cf shows a broad hump at energies more than 8 MeV. This is interpreted as a giant dipole resonance (GDR) of the fragments centered around 15 MeV. To understand how the GDR is populated in the fission process, one needs to measure the PFGS for the reactions with the mass yields different from the spontaneous fission of $$^{252}$$Cf, such as (n,f). The measurements of the PFGS for (n,f), however, are limited less than 9 MeV even in the recent experiment. This prompts us to make a new measurement to extend the know PFGS up to 20 MeV. The measurement has been carried out at the PF1B beam line of Institut Laue-Langevin. In this contribution we will present the results obtained the measurement.

The Radiation Assessment Detector (RAD) on the Mars Science Laboratory (MSL) has been measuring the radiation environment on the surface of Mars since August 6th 2012. In this work, several models such as GEANT4, PHITS, and HZETRN/OLTARIS are used to predict the radiation environment caused by galactic cosmic rays on Mars in order to compare and validate them with the experimental results. Although good agreement is found in many cases for GEANT4, PHITS and HZETRN/OLTARIS, some models still show large, sometimes order of magnitude, discrepancies in certain particle spectra. We have found that RAD data is helping make better choices of input parameters and physical models. These results help to predict dose rates for future manned missions as well as to perform shield optimization studies.

High-spin states of $$^{190}$$Pt have been reinvestigated using the $$^{176}$$Yb($$^{18}$$O, 4$$n$$) reaction at a beam energy of 88 MeV. The previously known positive parity band associated with the $$nu$$ $$i^{-2}_{13/2}$$ $$nu$$ $$h^{-1}_{9/2}$$ $$nu$$ $$j^{-1}$$ ($$nu j$$ being $$nu p_{3/2}$$ or $$nu f_{5/2}$$) configuration has been revised and extended significantly. A new negative parity band has been established and proposed to be based on the $$nu$$ $$i^{-3}_{13/2}$$ $$nu$$ $$j^{-1}$$ configuration. Possible structure evolution of the yrast line from predominantly vibrational to rotational with increasing spin is discussed with the help of E$$_gamma$$ over spin curves. Additionally, calculations of Total Routhian surfaces have been performed to investigate the band properties.

A TPC has been developed for J-PARC E42 experiment to search for H-dibaryon in ($$K^-$$, $$K^+$$) reaction. An event with 2 $$pi^-$$ and 2 protons decaying from H-dibaryon is searched for inside the TPC. The TPC has octagonal prism shape drift volume with about 50 cm diameter with 55 cm drift length filled with Ar-CH$$_{4}$$ (90:10) gas. At the end of the drift volume, 3-layer GEMs are equipped. In order to analyze momenta of produced particles, the TPC is applied with 1 T dipole magnetic field parallel to the drift electric field with a superconducting Helmholz magnet. In order to maximize the acceptance of H-dibaryon events, a diamond target is installed inside the TPC drift volume, in a cylindrical hole opened from the top to the middle of the drift volume. Since extremely high-rate $$K^-$$ beam is directly injected into the TPC drift volume to the target, a gating grid and GEMs are adopted to suppress positive-ion feedback.

The IS thermochemical water splitting process is considered to be one of the most promising clean and large-scale hydrogen production approaches. Much heat requirement of the HI distillation column largely affects the overall efficiency of hydrogen production. This study explored operating parameters of the distillation column to separate HI efficiently by distillation simulation of HI-H$$_{2}$$-H$$_{2}$$O solution of hyper-pseudo-azeotropic composition obtainable in the IS process. First, the vapor-liquid equilibrium database used in the simulation was validated using experimental data reported. Then, effect of the operating parameters, comprising HI mole fraction in distillate, number of column stages, feed location of the column, operating pressure, and feed composition, was analyzed on column properties such as reboiler heat duty. Optimum feed HI mole fraction, number of column stages, and feed location were determined. Feed composition changed tendency of the effect of operating pressure on reboiler heat duty.

By quantum Monte Carlo simulation of a realistic multi-orbital Anderson impurity model, we have studied the spin-orbit interaction (SOI) of an Fe impurity in Au host metal. We have shown, for the first time, that the SOI is strongly renormalized by the quantum spin fluctuation. Based on this mechanism, we could explain why the gigantic spin hall effect in Au with Fe impurities was observed in recent experiment, while it is not visible in the anomalous hall effect. In addition, we have shown that the SOI is strongly renormalized by the coulomb correlation $$U$$. Based on this picture, we could explain past discrepancies in the calculated orbital angular momenta for an Fe impurity in Au host.
