Kobayashi Y, Kazama S, Inoue K, Toyama T, Nagai Y, Haraya K, Mohamed HF, O'Rouke BE, Oshima N, Kinomura A, Suzuki R.
PMID: 24815092
J Phys Chem B. 2014 Jun 05;118(22):6007-14. doi: 10.1021/jp501706d. Epub 2014 May 21.

Positron annihilation lifetime spectroscopy (PALS) is applied to a series of bis(aniline)fluorene and bis(xylidine)fluorene-based cardo polyimide and bis(phenol)fluorene-based polysulfone membranes. It was found that favorable amounts of positronium (Ps, the positron-electron bound state) form in cardo polyimides with the...

Biochem Biophys Rep. 2017 Jan 26;9:322-329. doi: 10.1016/j.bbrep.2017.01.009. eCollection 2017 Mar.

We previously reported that ubiquitin-specific protease (USP) 2 in macrophages down-regulates genes associated with metabolic diseases, suggesting a putative anti-diabetic role for USP2 in macrophages. In this study, we evaluate this role at both cellular and individual levels. Isolated...

Prediction of background parenchymal enhancement on breast MRI using mammography, ultrasonography, and diffusion-weighted imaging.

PMID: 26412889
Nagoya J Med Sci. 2015 Aug;77(3):425-37.

This retrospective study assessed the effects of menopausal status and menstrual cycle on background parenchymal enhancement (BPE) of breast magnetic resonance imaging (MRI), and investigated whether the degree of BPE can be predicted by findings of mammography, ultrasonography (US),...

Multiferroic Vacancies at Ferroelectric PbTiO(3) Surfaces.

Physical review letters

Shimada T, Wang J, Araki Y, Mrovec M, Elsässer C, Kitamura T.
PMID: 26382700
Phys Rev Lett. 2015 Sep 04;115(10):107202. doi: 10.1103/PhysRevLett.115.107202. Epub 2015 Sep 03.

Multiferroics in nanoscale dimensions are promising for novel functional device paradigms, such as magnetoelectric memories, due to an intriguing cross-coupling between coexisting ferroelectric and (anti)ferromagnetic order parameters. However, the ferroic order is inevitably destroyed below the critical dimension of...

Quantum photonic network and physical layer security.

Philosophical transactions. Series A, Mathematical, physical, and engineering sciences

Sasaki M, Endo H, Fujiwara M, Kitamura M, Ito T, Shimizu R, Toyoshima M.

Philos Trans A Math Phys Eng Sci. 2017 Aug 06;375(2099). doi: 10.1098/rsta.2016.0243.

Quantum communication and quantum cryptography are expected to enhance the transmission rate and the security (confidentiality of data transmission), respectively. We study a new scheme which can potentially bridge an intermediate region covered by these two schemes, which is...

Phys Rev Lett. 2015 Aug 14;115(7):076801. doi: 10.1103/PhysRevLett.115.076801. Epub 2015 Aug 13.

In situ angle-resolved photoemission spectroscopy (ARPES) has been performed on SrVO_{3} ultrathin films, which show metallic quantum well (QW) states, to unveil the origin of the anomalous mass enhancement in the QW subbands. The line-shape analysis of the ARPES...

GyroWand: An Approach to IMU-Based Raycasting for Augmented Reality.

The combination of oxygen octahedral rotation and epitaxial strain provides a unique opportunity to tune the ferroelectric properties of perovskite superlattices. Here, through first-principles calculations, we demonstrate that the oxygen octahedral rotation predominates the ground state and ferroelectric properties...
