Nitrogen Sources for Phytoplankton in the Eastern Indian Ocean Determined From δ15N of Chlorophyll a and Divinylchlorophyll a

Autor: Yuta Isaji, C. Yoshikawa, N. O. Ogawa, K. Matsumoto, A. Makabe, S. Toyoda, N. F. Ishikawa, H. Ogawa, H. Saito, M. C. Honda, N. Ohkouchi

Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 23, Iss 4, Pp n/a-n/a (2022)

Abstract Nitrogen isotope analysis of chloropigments provides information on the sources of nitrogenous nutrients assimilated by phytoplankton. The abundant, ubiquitous chlorophyll a records nitrogen isotopic compositions (δ15N) of eukaryotic phytop

Emotional Modulation of Frontal Alpha Asymmetry - a Novel Biomarker of Mild Traumatic Brain Injury

Autor: Venla Kuusinen, Jari Peräkylä, Lihua Sun, Keith H. Ogawa, Kaisa M. Hartikainen

Publikováno v: Frontiers in Human Neuroscience, Vol 15 (2021)

Objective findings of brain injury or dysfunction are typically lacking in mild traumatic brain injury (MTBI) despite prolonged post-concussion symptoms in some patients. Thus, there is a need for objective biomarkers of MTBI that reflect altered bra

Search for sub-GeV dark matter by annual modulation using XMASS-I detector

Publikováno v: Physics Letters B, Vol 795, Iss , Pp 308-313 (2019)

A search for dark matter (DM) with mass in the sub-GeV region (0.32–1 GeV) was conducted by looking for an annual modulation signal in XMASS, a single-phase liquid xenon detector. Inelastic nuclear scattering accompanied by bremsstrahlung emission

A direct dark matter search in XMASS-I

Publikováno v: Physics Letters B, Vol 789, Iss , Pp 45-53 (2019)

A search for dark matter using an underground single-phase liquid xenon detector was conducted at the Kamioka Observatory in Japan, particularly for Weakly Interacting Massive Particles (WIMPs). We have used 705.9 live days of data in a fiducial volu

Search for dark matter in the form of hidden photons and axion-like particles in the XMASS detector

Publikováno v: Physics Letters B, Vol 787, Iss , Pp 153-158 (2018)

Hidden photons and axion-like particles are candidates for cold dark matter if they were produced non-thermally in the early universe. We conducted a search for both of these bosons using 800 live-days of data from the XMASS detector with 327 kg of l

Temporal Profiles of Symptom Scores After Palliative Radiotherapy for Bleeding Gastric Cancer With Adjustment for the Palliative Prognostic Index: An Exploratory Analysis of a Multicentre Prospective Observational Study (JROSG 17–3)

Publikováno v: Clinical Oncology. 34:e505-e514

Although palliative radiotherapy for gastric cancer may improve some symptoms, it may also have a negative impact due to its toxicity. We investigated whether symptoms improved after radiotherapy with adjustment for the Palliative Prognostic Index (P

Search for exotic neutrino-electron interactions using solar neutrinos in XMASS-I

Publikováno v: Physics Letters B, Vol 809, Iss , Pp 135741- (2020)

We have searched for exotic neutrino-electron interactions that could be produced by a neutrino millicharge, by a neutrino magnetic moment, or by dark photons using solar neutrinos in the XMASS-I liquid xenon detector. We observed no significant sign
