Properties and Applications of Magnetic Tunnel Junctions

G. Reiss,H. Brückl,A. Thomas,M. Justus,D. Meyners,H. Koop 한국자기학회 2003 Journal of Magnetics Vol.8 No.1

The discoveries of antiferromagnetic coupling in Fe/Cr multilayers by Grünberg, the Giant Magneto Resistance by Fert and Grünberg and a large tunneling magnetoresistance at room temperature by Moodera have triggered enormous research on magnetic thin films and magnetoelectronic devices. Large opportunities are especially opened by the spin dependent tunneling resistance, where a strong dependence of the tunneling current on an external magnetic field can be found. We will briefly address important basic properties of these junctions like thermal, magnetic and dielectric stability and discuss scaling issues down to junction sizes below 0.01 ㎛² with respect to single domain behavior, switching properties and edge coupling effects. The second part will give an overview on applications beyond the use of the tunneling elements as storage cells in MRAMs. This concerns mainly field programmable logic circuits, where we demonstrate the clocked operation of a programmed AND gate. The second ‘unconventional’ feature is the use as sensing elements in DNA or protein biochips, where molecules marked magnetically with commercial beads can be detected via the dipole stray field in a highly sensitive and relatively simple way.

KEDO: WHICH WAY FROM HERE?

MitchellB.Reiss 경남대학교 극동문제연구소 2002 ASIAN PERSPECTIVE Vol.26 No.1

Contrary to the early skepticism, the Korean Peninsula Energy Development Organization (KEDO) has not only survived; in some ways it has actually flourished. KEDO and the DPRK (North Korea) have been able to forge a solid working relationship, which has been reflected in numerous agreements that interpret and implement the original commitments set forth in the 1994 Agreed Framework. More important is what KEDO has prevented¾including the halting of its reprocessing of fissile material for atomic bombs. Inspectors from the International Atomic Energy Agency (IAEA) have been allowed continuous access to monitor this “freeze.” To date, there have been no publicly confirmed reports of the North cheating on this arrangement. Yet If KEDO were judged on its ability to efficiently manage an international construction project, it would be fortunate to receive a “gentleman’s C.” But that may be the wrong way to assess its performance. Fundamentally, KEDO is a political endeavor, not a commercial project, and in that respect it has made a substantial contribution to peace building. Even without knowing the ultimate outcome of the KEDO project, its stabilizing presence has allowed the DPRK and the major powers in the region to begin a process of diplomatic and economic engagement.

Cosmetic outcomes of simple facial laceration suturing in the pediatric emergency department

Eyal Reiss,Yoav Gronovich,Eyal Heiman,Elad Sela,Giora Weiser 대한소아응급의학회 2024 대한소아응급의학회지 Vol.11 No.2

Purpose: The long-term cosmetic outcomes of simple facial lacerations have not been well addressed, specifically regarding those of suturing by pediatric emergency physicians (PEPs) and plastic surgery (PS) residents. Methods: A retrospective study was performed at the pediatric emergency department of Shaare Zedek Medical Center in Jerusalem, Israel. Cosmetic outcomes of simple facial lacerations sutured within 1 year of the study were reviewed using digital photographs taken by legal guardians of children sutured in the department. The photographs were reviewed and rated blindly using the Stony Brook scar score as measures of cosmetic outcomes by 2 plastic surgeons and 1 PEP, as well as the general numeric score (GNS) rated by the guardians and the 3 doctors. The scores were compared between children sutured by PEPs (PEP group) and those sutured by PS residents (PS group). A sample size of 50 children in each study group was calculated to have enough power to show a difference. Results: Among a total of 108 children who participated in the study (median age, 4.0 years [interquartile range, 3.0-7.0]), 57 and 51 were sutured by PEPs and PS residents, respectively. Guardian-rated median GNS showed no difference between the 2 groups (PEP, 90.0 [70.0-95.0] vs. PS, 90.0 [60.0-90.0]; P = 0.310). In contrast, doctor-rated median GNS was higher in the PEP group (PEP, 75.0 [63.3-86.7] vs. PS, 70.0 [53.3-83.3]; P = 0.046). A Stony Brook scar score of 3 or higher was similarly frequent in both groups (PEP, 87.7% vs. PS, 74.5%; P = 0.173) with a low interrater agreement (Kappa = 0.36). Conclusion: Cosmetic outcomes of simple facial lacerations in the pediatric emergency department were favorable regardless of the specialty or expertise of doctors. The guardians were more satisfied with the outcomes, compared to the doctors.

Drifting apart? The U,S, -ROK alliance at risk

( Mitchell B Reiss ) 한국국방연구원 2009 The Korean Journal of Defense Analysis Vol.21 No.1

Given the success of the U.S.-ROK alliance over the past five and half decades, it is far easier to envision that it will remain undisturbed than to imagine major change, let alone the end of the alliance. Yet past history is no guarantee of future success. Major shifts in American foreign policy, new transnational challenges and a changing political, economic, and security environment in Northeast Asia, call into question whether the alliance will last another 10 years, let alone another half century. By the start of the twenty-first century, the United States had increasingly conceptualized the alliance in regional or even global terms, whereas the ROK military, despite some impressive blue-water naval assets, was still wedded to the mission of peninsular defense. Ideally, the United States would like the ROK to join with U.S. forces in addressing regional and global contingencies, in addition to fulfilling its primary missions to deter and, if necessary, defeat North Korea. Yet America`s reorientation of its forces on the Korean peninsula and the ROK`s military transformation were driven more by domestic political concerns than by jointly shared security imperatives. As a result, larger questions about the future of the alliance went begging. With both partners transitioning to new force structures, these measures portended an alliance that was drifting apart, not a maturing alliance that was becoming a more equal and cohesive partnership. Questions remain unanswered, or even unasked, about whether the two partners agree on the strategic environment in the region and the respective roles both should play. Although there have been discussions on the ````future of the alliance,```` these have focused on U.S. base realignment and other details, not on the future security environment in the region and its larger strategic implications. It is these offshore missions, not North Korea, where threat assessments will likely diverge and where alliance disagreements will arise in the future. In short, the two parties have yet to confront the full implications of the military and defense decisions of the past few years, often undertaken unilaterally and attuned more to domestic audiences than to strategic realities. The ability to paper over a lack of common purpose and shared vision may be useful as a temporary placeholder, but it will not provide an adequate foundation for the future viability of the alliance. The good news is that consensus exists in both countries that the alliance needs to be preserved; the bad news is that charting the way ahead is neither easy nor obvious. The risk is that without the development of a clear and common vision of a shared future with defined and mutually agreed-upon roles, the United States and South Korea will gradually drift apart, along with a partnership that has proved so successful over the past half century.

Child Development : Genetic and Environmental Influences on Dispositional Optimism and Depressive Symptoms in Adolescence

( Jong Il Yuh ),( Jenae M. Neiderhiser ),( David Reiss ) 대한가정학회 2010 International Journal of Human Ecology Vol.11 No.2

This study explored genetic and environmental contributions to optimism, depressive symptoms, and the association between the two using a genetically informative sample from the Nonshared Environment and Adolescent Development project (NEAD: D. Reiss; J. M. Neiderhiser; E. M. Hetherington; & R. Plomin, 2000)+. At Time 1 of the longitudinal NEAD study, the sample consisted of 720 same-sex twins and sibling pairs from two parent families. The study used parent, adolescent, and observer ratings of depressive symptoms as well as adolescent ratings of optimism. The results revealed that genetic influences explained approximately half of the variability in optimism and depressive symptoms. Nonshared environmental influences also substantially contributed to optimism and depressive symptoms. Bivariate genetic analyses (which partitioned the covariance between optimism and depressive symptoms into genetic and environmental components) indicated that genetic influences accounted for a moderate percentage of the association.
