The sparse phase retrieval aims to recover the signal from quadratic measurements. However, measurements are often affected by outliers and asymmetric distribution noise. This paper introduces a novel method that combines quantile regression L1/2-regularizer. It is non-convex, non-smooth, non-Lipschitz optimization problem. We propose an efficient algorithm based on Alternating Direction Method...

The mechanism of experimentally observed high-temperature superconductivity (HTSC) in thin FeSe films on SrTiO3-type substrates has been theoretically investigated. Applying the theory large-radius bipolaronic states developed based exact Hamiltonian electron-phonon interaction for arbitrary multilayer structures, Cooper pairing polarons monolayers SrTiO3 is investigated a...

Abstract. We report measurements of atmospheric C3H8 from analysis ground-based solar absorption spectra the Jet Propulsion Laboratory (JPL) MkIV interferometer. Using strong Q-branch feature at 2967 cm?1, we can measure in locations where its abundance is enhanced by proximity to sources (e.g., large natural gas fields, megacities). A case study Fort Sumner, New Mexico, shows that amounts are ...

Along with the popularity of environmental protection concepts, treatment water pollution attracts widespread attention, among which, research on Bi-based semiconductor photocatalytic degradation technology has made great progress. However, development such bismuth-based composites still remains a challenging task due to difficult recovery and low catalytic efficiency. Herein, novel CC/BiPO4/Bi...

Abstract. Measurements of the pollution trace gases ethane (C2H6), ethyne (C2H2), formic acid (HCOOH), and peroxyacetyl nitrate (PAN) were performed in North Atlantic upper troposphere lowermost stratosphere (UTLS) region with airborne limb imager GLORIA (Gimballed Limb Observer for Radiance Imaging Atmosphere) high spatial resolution down to cloud top. Observations made during flights German r...

Abstract. Soil evaporation is a key process in the water cycle and can be conveniently quantified using ?2H ?18O bulk surface soil (BW). However, recent research shows that larger pores evaporates first differs from smaller ?18O, which disqualifies quantification of BW ?18O. We hypothesized had different isotopic compositions evaporating (EW). Therefore, our objectives were to test this hypothe...

Abstract. In this study we evaluate simulated surface SO2 and sulfate (SO42-) concentrations from the United Kingdom Earth System Model (UKESM1) against observations ground-based measurement networks in USA Europe for period 1987–2014. We find that UKESM1 captures historical trend decreasing of atmospheric SO42- both over However, polluted regions eastern Europe, over-predicts by a factor 3 whi...

Abstract. Headspace analysis of CO2 frequently has been used to quantify the concentration in fresh water. According basic chemical theory, not considering equilibration carbonate system sample vials will result a systematic error. By analysing potential error for different types water and experimental conditions, we show that incurred by headspace is less than 5 % typical samples from boreal s...

Abstract. To provide long-term air pollutant exposure estimates for epidemiological studies, it is essential to test the feasibility of developing land-use regression (LUR) models using only routine quality measurement data and evaluate transferability LUR between nearby cities. In this study, we developed evaluated intercity annual-average ambient respirable suspended particulates (PM10), fine...

Abstract. Outlet glaciers that flow through the Transantarctic Mountains (TAM) experienced changes in ice thickness greater than other coastal regions of Antarctica during glacial maxima. As a result, ice-free areas are currently exposed may have been covered by at various points Cenozoic, complicating our understanding ecological succession TAM soils. Our knowledge extent on small spatial scal...
