Weakened overturning and tide control the properties of Oyashio Intermediate Water, a key water mass in the North Pacific

open access: yesScientific Reports, 2021
The western subarctic Pacific exhibits major biological productivity fed by the Oyashio Current and its two source waters: Western Subarctic Water, which supplies nutrients from the subarctic Pacific, and cold Okhotsk Sea Intermediate Water (OSIW), which

Epitaxial growth of high-quality GaN with a high growth rate at low temperatures by radical-enhanced metalorganic chemical vapor deposition

open access: yesScientific Reports
Using our recently developed radical-enhanced metalorganic chemical vapor deposition (REMOCVD) technique, we have grown gallium nitride (GaN) on bulk GaN and GaN on Si templates. Three features make up this system: (1) applying very high-frequency power (

Meridional distribution and seasonal variation of stable oxygen isotope ratio of precipitation in the Southern Ocean

open access: yesAntarctic Record, 2010
The stable oxygen isotope ratio(δ^O) in precipitation is known to have important meridional and seasonal variations, but there are almost no measurements of δ^O in precipitation over polar oceans.

Genomic Characteristics of Desulfonema ishimotonii Tokyo 01T Implying Horizontal Gene Transfer Among Phylogenetically Dispersed Filamentous Gliding Bacteria

open access: yesFrontiers in Microbiology, 2019
Desulfonema ishimotonii strain Tokyo 01T is a filamentous sulfate-reducing bacterium isolated from a marine sediment. In this study, the genome of this strain was sequenced and analyzed with a focus on gene transfer from phylogenetically distant ...

A compound-specific method for measuring the stable carbon isotopic composition of amino acids: elimination of the effect of isotopic fractionation during derivatization

open access: yesProgress in Earth and Planetary Science
Compound-specific isotope analysis (CSIA) of carbon and nitrogen within amino acids by gas chromatography/isotope ratio mass spectrometry (GC/IRMS) has been employed as a powerful tool for estimating the trophic tendency and resource utilization of ...

Unconventional fractional quantum Hall states and Wigner crystallization in suspended Corbino graphene

open access: yesNature Communications, 2018
Understanding of ordered phases of interacting electrons in 2D systems is a fundamental many-body physics problem. Here, the authors report unconventional fractional quantum Hall phases in graphene Corbino devices originating from residual interactions ...

Enhanced expression of genes in the brains of larvae of Mamestra brassicae (Lepidoptera: Noctuidae) exposed to short daylength or fed Dopa

open access: yesEuropean Journal of Entomology, 2003
The cabbage armyworm, Mamestra brassicae, enters diapause in the early pupal stage. Pupal diapause is induced by rearing the larvae under short day lengths.

Continuous time crystal coupled to a mechanical mode as a cavity-optomechanics-like platform

open access: yesNature Communications
Time crystals are an enigmatic phase of matter in which a quantum mechanical system displays repetitive, observable motion – they spontaneously break the time translation symmetry.

Fractionation of nitrogen isotopes in the enzymatic deamination of alanine: an insight into the quantitative evaluation of anaerobic metabolism in ecosystems

open access: yesProgress in Earth and Planetary Science
Nitrogen isotope ratios of amino acids have been employed as a tool for illustrating the resource utilization of organisms and the trophic transfer between organisms in food webs.
