Park J, Yamazaki Y, Iwanaga M, Ahn S, Jeon H, Fujiwara T, Yao T.
PMID: 20588626
Opt Express. 2010 Apr 12;18(8):7851-6. doi: 10.1364/OE.18.007851.

We report on the second harmonic generation (SHG) in 2D periodically polarity-inverted (PPI) ZnO heterostructures. The grating structures with nanometer-scale periodicity are fabricated on (0001) Al(2)O(3) substrates by using the in situ polarity inversion method. The achievements of SHG...

Iwanaga S, Toberer ES, LaLonde A, Snyder GJ.
PMID: 21721707
Rev Sci Instrum. 2011 Jun;82(6):063905. doi: 10.1063/1.3601358.

A high temperature Seebeck coefficient measurement apparatus with various features to minimize typical sources of error is designed and built. Common sources of temperature and voltage measurement error are described and principles to overcome these are proposed. With these...

Subwavelength electromagnetic dynamics in stacked complementary plasmonic crystal slabs.

Optics express

Iwanaga M.
PMID: 20720917
Opt Express. 2010 Jul 19;18(15):15389-98. doi: 10.1364/OE.18.015389.

Resonant electromagnetic fields in stacked complementary plasmonic crystal slabs (sc-PlCSs) are numerically explored in subwavelength dimensions. It is found that the local plasmon resonances in the sc-PlCSs are composite states of locally enhanced electric and magnetic fields. Two sc-PlCSs...

Chemistry of anthracene-acetylene oligomers. XVII. Synthesis, structure, and dynamic behavior of 1,8-anthrylene pentamers and hexamers with acetylene linkers.

Organic & biomolecular chemistry

Toyota S, Kawakami T, Shinnishi R, Sugiki R, Suzuki S, Iwanaga T.
PMID: 20835490
Org Biomol Chem. 2010 Nov 07;8(21):4997-5006. doi: 10.1039/c0ob00290a. Epub 2010 Sep 13.

Three types of cyclic oligomers consisting of five or six 1,8-anthrylene units with acetylene linkers were synthesized by macrocyclization of the corresponding acyclic precursors with coupling reactions. DFT calculations at the M05/3-21G level revealed that the pentamers had a...

Relationship between Sympathetic Skin Responses and Auditory Hypersensitivity to Different Auditory Stimuli.

Journal of physical therapy science

PMID: 25140103
J Phys Ther Sci. 2014 Jul;26(7):1087-91. doi: 10.1589/jpts.26.1087. Epub 2014 Jul 30.

[Purpose] Auditory hypersensitivity has been widely reported in patients with autism spectrum disorders. However, the neurological background of auditory hypersensitivity is currently not clear. The present study examined the relationship between sympathetic nervous system responses and auditory hypersensitivity induced...

PMID: 30214849
Cureus. 2018 Jul 10;10(7):e2961. doi: 10.7759/cureus.2961.

Herniations of the brain and/or meninges through an opening of the skull often occur through the foramen magnum, e.g., Chiari malformations and encephaloceles. The herniation of brain matter through the cribriform plate is a rare incident and has not...

Penetrating Orbital Injuries: A Review.

Cureus

Mashriqi F, Iwanaga J, Loukas M, D'Antoni AV, Tubbs RS.

Cureus. 2017 Sep 29;9(9):e1725. doi: 10.7759/cureus.1725.

Penetrating injuries to the orbit represent a small but very complicated portion of head injuries. Because of the close proximity to many vital structures, any penetrating orbital injury requires a multidisciplinary follow-up. Cases of penetrating injuries have flooded the...

Imaging Characteristics of Dural Arteriovenous Fistulas Involving the Vein of Galen: A Comprehensive Review.

Cureus

Kassem MW, Choi PJ, Iwanaga J, Mortazavi MM, Tubbs RS.
