Genome-wide analysis of histone modifications can contribute to the identification of candidate cis-regulatory regions in the threespine stickleback fish

Autor: Genta Okude, Yo Y. Yamasaki, Atsushi Toyoda, Seiichi Mori, Jun Kitano

Publikováno v: BMC Genomics, Vol 25, Iss 1, Pp 1-14 (2024)

Abstract Background Cis-regulatory mutations often underlie phenotypic evolution. However, because identifying the locations of promoters and enhancers in non-coding regions is challenging, we have fewer examples of identified causative cis-regulator

Publikováno v: Ecology and Evolution, Vol 11, Iss 19, Pp 13283-13294 (2021)

Abstract Countershading, characterized by a darker dorsal surface and lighter ventral surface, is common among many animals. This dorsoventral pigment polarity is often thought to be adaptive coloration for camouflage. By contrast, noncountershaded (

Frustration-driven magnetic fluctuations as the origin of the low-temperature skyrmion phase in Co7Zn7Mn6

Publikováno v: npj Quantum Materials, Vol 6, Iss 1, Pp 1-8 (2021)

Abstract In chiral cubic helimagnets, phases of magnetic skyrmions—topologically protected spin whirls—are stabilized by thermal fluctuations over a narrow region directly below the magnetic ordering temperature T c. Due to often being touted for

Particle-size dependent structural transformation of skyrmion lattice

Autor: R. Takagi, Y. Yamasaki, T. Yokouchi, V. Ukleev, Y. Yokoyama, H. Nakao, T. Arima, Y. Tokura, S. Seki

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-7 (2020)

Skyrmions are topological spin textures and are of great interest due to their impressive stability. Here, by sweeping an applied magnetic field, the authors observe a change in the skyrmion lattice structure, shedding light on the relation between s

Fabrication of a 64-Pixel TES Microcalorimeter Array With Iron Absorbers Uniquely Designed for 14.4-keV Solar Axion Search

Autor: Yuta Yagi, Tasuku Hayashi, Keita Tanaka, Rikuta Miyagawa, Ryo Ota, Noriko Y. Yamasaki, Kazuhisa Mitsuda, Nao Yoshida, Mikiko Saito, Takayuki Homma

Publikováno v: IEEE Transactions on Applied Superconductivity. 33:1-5

If a hypothetical elementary particle called an axion exists, to solve the strong CP problem, a 57Fe nucleus in the solar core could emit a 14.4-keV monochromatic axion through the M1 transition. If such axions are once more transformed into photons

Publikováno v: Clinical and Experimental Obstetrics & Gynecology, Vol 47, Iss 2, Pp 312-314 (2020)

Introduction: Struma ovarii is rare ovarian tumor. Almost 95% of it is indicated as the benign tumor. Therefore, it is important to be diagnosed preoperatively. A case that is diagnosed successfully as a struma ovarii preoperatively, is presented. Ca
