Meteorological and sea surface water measurement data from Icebreaker Research Vessel ARAON for 2010-2019 Arctic research expeditions
Despite of its economic and scientific significances with mineral resources, the Northern Sea Routes, and climate change, the Arctic Ocean has been a challenge for long-term continuous environmental observations. Since its inception in 2009, the ice-breaker research vessel ARAON has been conducting an annual expedition in the Arctic Ocean for the last 10 years from 2010. All the Arctic expeditions have been carried out mainly in August-September when the sea ice extent shrinks and the thickness becomes relatively thin around the Bering Sea, Chukchi Sea, Beaufort Sea, and high latitudes over the Russia, the US, and Canada. IBRV ARAON can conduct research activities through a variety of research equipment such as on-board meteorological data and surface temperature & salinity monitoring data of seawater. In this study, meteorological observation elements including solar radiation, air temperature, relative humidity, wind speed, and wind direction are presented. In addition, sea surface water temperature and salinity monitoring elements including water temperature, salinity, conductivity, and sound speed are presented

Observation of Supercurrent in PbIn-Graphene-PbIn Josephson Junction
Superconductor-graphene-superconductor (SGS) junction provides a unique
platform to study relativistic electrodynamics of Dirac fermions combined with
proximity-induced superconductivity. We report observation of the Josephson
effect in proximity-coupled superconducting junctions of graphene in contact
with Pb1-xInx (x=0.07) electrodes for temperatures as high as T = 4.8K, with a
large IcRn (~ 255 microV). This demonstrates that Pb1-xInx SGS junction would
facilitate the development of the superconducting quantum information devices
and superconductor-enhanced phase-coherent transport of graphene.Comment: 8 pages, 7 figures, accepted in PR

Characterization of altered molecular mechanisms in Parkinsons disease through cell type-resolved multiomics analyses.
Parkinsons disease (PD) is a progressive neurodegenerative disorder. However, cell type-dependent transcriptional regulatory programs responsible for PD pathogenesis remain elusive. Here, we establish transcriptomic and epigenomic landscapes of the substantia nigra by profiling 113,207 nuclei obtained from healthy controls and patients with PD. Our multiomics data integration provides cell type annotation of 128,724 cis-regulatory elements (cREs) and uncovers cell type-specific dysregulations in cREs with a strong transcriptional influence on genes implicated in PD. The establishment of high-resolution three-dimensional chromatin contact maps identifies 656 target genes of dysregulated cREs and genetic risk loci, uncovering both potential and known PD risk genes. Notably, these candidate genes exhibit modular gene expression patterns with unique molecular signatures in distinct cell types, highlighting altered molecular mechanisms in dopaminergic neurons and glial cells including oligodendrocytes and microglia. Together, our single-cell transcriptome and epigenome reveal cell type-specific disruption in transcriptional regulations related to PD
Conductivity Enhancement of Nickel Oxide by Copper Cation Codoping for Hybrid Organic-Inorganic Light-Emitting Diodes
We
demonstrate a CuĀ(I) and CuĀ(II) codoped nickelĀ(II) oxide (NiO<sub><i>x</i></sub>) hole injection layer (HIL) for solution-processed
hybrid organic-inorganic light-emitting diodes (HyLEDs). Codoped NiO<sub><i>x</i></sub> films show no degradation on optical properties
in the visible range (400ā700 nm) but have enhanced electrical
properties compared to those of conventional CuĀ(II)-only doped NiO<sub><i>x</i></sub> film. Codoped NiO<sub><i>x</i></sub> film shows an over four times increased vertical current in
comparison with that of NiO<sub><i>x</i></sub> in conductive
atomic force microscopy (c-AFM) configuration. Moreover, the hole
injection ability of codoped NiO<sub><i>x</i></sub> is also
improved, which has ionization energy of 5.45 eV, 0.14 eV higher than
the value of NiO<sub><i>x</i></sub> film. These improvements
are a consequence of surface chemical composition change in NiO<sub><i>x</i></sub> due to Cu cation codoping. More off-stoichiometric
NiO<sub><i>x</i></sub> formed by codoping includes a large
amount of Ni vacancies, which lead to better electrical properties.
Density functional theory calculations also show that Cu doped NiO
model structure with Ni vacancy contains diverse oxidation states
of Ni based on both density of states and partial atomic charge analysis.
Finally, HyLEDs of Cu codoped NiO<sub><i>x</i></sub> HIL
have higher performance comparing with those of pristine NiO<sub><i>x</i></sub>. The current efficiency of devices with NiO<sub><i>x</i></sub> and codoped NiO<sub><i>x</i></sub> HIL are 11.2 and 15.4 cd/A, respectively. Therefore, codoped NiO<sub><i>x</i></sub> is applicable to various optoelectronic
devices due to simple solāgel process and enhanced doping efficiency
