PMID: 25491783
Endocrinol Metab (Seoul). 2015 Sep;30(3):361-70. doi: 10.3803/EnM.2015.30.3.361. Epub 2014 Dec 09.

BACKGROUND: In mammals, the master circadian pacemaker is localized in an area of the ventral hypothalamus known as the suprachiasmatic nucleus (SCN). Previous studies have shown that pacemaker neurons in the SCN are highly coupled to one another, and...

BACKGROUND/AIMS: Colon transit time (CTT) is a useful diagnostic tool in chronic constipation, but requires good patient compliance. We analyzed the correlation between the gas volume score (GVS) and CTT in patients with chronic constipation.METHODS: The study included 145...

A study of threshold switching of NbO2 using atom probe tomography and transmission electron microscopy.

Micron (Oxford, England : 1993)

Lee JH, Cha EJ, Kim YT, Chae BK, Kim JJ, Lee SY, Hwang HS, Park CG.
PMID: 26381075
Micron. 2015 Dec;79:101-9. doi: 10.1016/j.micron.2015.07.015. Epub 2015 Aug 28.

Threshold switching is a phenomenon where the resistivity of an insulating material changes and the insulator exhibits metallic behavior. This could be explained by phase transformation in oxide materials; however, this behavior is also seen in amorphous insulators. In...

ACS applied materials & interfaces

Acharya SK, Nallagatla RV, Togibasa O, Lee BW, Liu C, Jung CU, Park BH, Park JY, Cho Y, Kim DW, Jo J, Kwon DH, Kim M, Hwang CS, Chae SC.
PMID: 26955744
ACS Appl Mater Interfaces. 2016 Mar;8(12):7902-11. doi: 10.1021/acsami.6b00647. Epub 2016 Mar 18.

Resistive switching memory, which is mostly based on polycrystalline thin films, suffers from wide distributions in switching parameters-including set voltage, reset voltage, and resistance-in their low- and high-resistance states. One of the most commonly used methods to overcome this...

Wide-Range Probing of Dzyaloshinskii-Moriya Interaction.

Scientific reports

Kim DH, Yoo SC, Kim DY, Min BC, Choe SB.
PMID: 28361907
Sci Rep. 2017 Mar 31;7:45498. doi: 10.1038/srep45498.

The Dzyaloshinskii-Moriya interaction (DMI) in magnetic objects is of enormous interest, because it generates built-in chirality of magnetic domain walls (DWs) and topologically protected skyrmions, leading to efficient motion driven by spin-orbit torques. Because of its importance for both...
