<P>Graphene barristors are a novel type of electronic switching device with excellent performance, which surpass the low on–off ratios that limit the operation of conventional graphene transistors. In barristors, a gate bias is used to vary graphene’s Fermi level, which in turn controls the height and resistance of a Schottky barrier at a graphene/semiconductor heterojunction. Here we demonstrate that the switching characteristic of a thin-film ZnO/graphene device with simple geometry results from tunneling current across the Schottky barriers formed at the ZnO/graphene heterojunctions. Direct characterization of the current–voltage−temperature relationship of the heterojunctions by ac-impedance spectroscopy reveals that this relationship is controlled predominantly by field emission, unlike most graphene barristors in which thermionic emission is observed. This governing mechanism makes the device unique among graphene barristors, while also having the advantages of simple fabrication and outstanding performance.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/aamick/2015/aamick.2015.7.issue-33/acsami.5b03380/production/images/medium/am-2015-03380u_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/am5b03380'>ACS Electronic Supporting Info</A></P>

Acute Operative Management of Osteoporotic Vertebral Compression Fractures Is Associated with Decreased Morbidity

Mills Emily S.,Ton Andy T.,Bouz Gabriel,Alluri Ram K.,Hah Raymond J. 대한척추외과학회 2022 Asian Spine Journal Vol.16 No.5

Study Design: Retrospective national database study design.Purpose: This study was designed to determine whether acute percutaneous vertebral augmentation (PVA) alters morbidity compared with nonoperative management.Overview of Literature: Osteoporotic vertebral compression fractures (OCFs) are common and represent a large economic and patient burden. Several recent studies have focused on whether PVA offers benefits compared with nonoperative treatment.Methods: A retrospective cohort analysis was conducted using the Nationwide Inpatient Sample from 2015 to 2018. Patients with nonelective admissions for OCFs were identified using International Classification of Diseases (10th edition) codes. The exclusion criteria included age of less than 50 years, fusion and decompression procedures, and the presence of neoplasms and infections. Propensity score matching was implemented to construct 2:1 matched cohorts with similar comorbidities at admission. The patients were divided into the operative and nonoperative treatment groups. Univariate and multivariate regression analyses were performed to compare differences in in-hospital complication rates between the groups. All <i>p</i>-values of less than 0.05 were considered significant.Results: We identified 14,850 patients in the operative group and 29,700 patients in the nonoperative group. In the multivariate analysis, operative treatment was associated with significantly lower rates of pneumonia (odds ratio [OR], 0.75; <i>p</i><0.001), acute respiratory failure (OR, 0.84; <i>p</i>=0.009), myocardial infarction (OR, 0.20; <i>p</i><0.001), acute heart failure (OR, 0.80; <i>p</i>=0.001), cardiogenic shock (OR, 0.23; <i>p</i>=0.001), sepsis (OR, 0.39; <i>p</i><0.001), septic shock (OR 0.50; <i>p</i><0.001), and pressure ulcerations (OR, 0.71; <i>p</i><0.001). However, operative treatment was associated with a significantly greater risk of acute renal failure (OR, 1.19; <i>p</i><0.001) than nonoperative treatment.Conclusions: Patients who undergo acute PVA for OCFs have lower rates of respiratory complications, cardiac complications, sepsis, and pressure ulcerations while having a higher risk of acute renal failure.

A simple method for estimating the major nuclide fractional fission rates within light water and advanced gas cooled reactors

Mills, R.W.,Slingsby, B.M.,Coleman, J.,Collins, R.,Holt, G.,Metelko, C.,Schnellbach, Y. Korean Nuclear Society 2020 Nuclear Engineering and Technology Vol.52 No.9

The standard method for calculating anti-neutrino emissions from a reactor involves knowing the fractional fission rates for the most important fissioning nuclides in the reactor. To calculate these rates requires detailed reactor physics calculations based upon the reactor design, fuel design, burnup dependent fuel composition, location of specific fuel assemblies in the core and detailed operational data from the reactor. This has only been published for a few reactors during specific time periods, whereas to be of practical use for anti-neutrino reactor monitoring it is necessary to be able to predict these on the publicly available information from any reactor, especially if using these data to subtract the anti-neutrino signal from other reactors to identify an undeclared reactor and monitor its operation. This paper proposes a method to estimate the fission fractions for a specific reactor based upon publicly available information and provides a database based upon a series of spent fuel inventory calculations using the FISPIN10 code and its associated data libraries.

'Timber And Wood In A Nation' : Australian Forest History Historiography

Mills, Jenny Australian Studies Institute 1997 Journal of Australian studies Vol.4 No.1

This forest philosophy was preached often by Charles Edward Lane poole when he was head of the Australian Forestry School in Canberra in the 1930's. Lane Poole was trained as a scientific forester at the famous French forestry school at Nantes, L'Ecole Nationale des Eaux et Foets. To explain Australian forest history it is necessary to explain its derivations which are twofold.

Blue bottle light: lecture demonstrations of homogeneous and heterogeneous photo-induced electron transfer reactions

Mills, Andrew,Lawrie, Katherine,McFarlane, Michael Korean Society of Photoscience 2009 Photochemical & photobiological sciences Vol.8 No.3

The classic, non-photochemical blue bottle experiment involves the reaction of methylene blue (MB) with deprotonated glucose, to form a bleached form of the dye, leuco-methylene blue (LMB), and subsequent colour recovery by shaking with air. This reaction is a popular demonstrator of key principles in kinetics and reaction mechanisms. Here it is modified so as to highlight features of homogenous and heterogeneous photoinduced electron transfer (PET) (Pure Appl. Chem., 2007, 79, 293-465) reactions, i.e. blue bottle light experiments. The homogeneous blue bottle light experiment uses methylene blue, MB, as the photo-sensitizer and triethanolamine as the sacrificial electron donor. Visible light irradiation of this system leads to its rapid bleaching, followed by the ready restoration of its original colour upon shaking away from the light source. The heterogeneous blue bottle light experiment uses titania as the photo-sensitizer, MB as a redox indicator and glucose as the sacrificial electron donor. UVA light irradiation of this system leads to the rapid bleaching of the MB and the gradual restoration of its original colour with shaking and standing. The latter 'dark' step can be made facile and more demonstrator-friendly by using platinised titania particles. These two photochemical versions of the blue bottle experiment are used to explore the factors which underpin homogeneous and heterogeneous PET reactions and provide useful demonstrations of homogeneous and heterogeneous photochemistry.

Memories of The Last Hwaraengi, Kim Junghee

Simon Mills 한국국악학회 2020 한국음악연구 Vol.67 No.-

2019년 12월 비극적으로 삶을 마친 김정희는 동해안굿 전통의 주축적인 인물이었다. 그는 뛰어난 음악성과 열정을 가진 음악인이었고, 동해안굿의 오랜 전통을 새로운 전통으로 전환한 핵심적 역할을 한 인물이었다. 그는 동해안 세습무계에서 태어나고 자란 마지막 예인으로서, 마지막 화랭이로 여겨진다. 그렇기에 그는 과거에 구축된 예술세계의 정체성을 강화한 예인이다. 동시에 그는 동해안 굿예술이 마을굿을 뛰어넘어 새로운 예술세계를 창출하는데 주도적 역할을 했다. 이글에서는 김정희의 인생과 뛰어난 예술적 재능을 되돌아보면서 한 인간과 그의 음악에 대한 심층적 분석을 하고자 한다. 이글은 그의 인생을 통해 예술세계와 발자취를 형성한 요인과 과정을 되돌아보고, 교육자와 연주자로서의 그의 다양한 공헌을 되새기고, 그의 독특한 음악스타일을 규명하고, 그의 인생을 바친 전통에서의 막대한 영향을 밝히고자 한다. 이글은 필자가 1999~2019년 사이에 수집한 광범위한 추억에 의한 것이다. 이는 김정희 자신의 회고, 그의 집단 구성원의 기억, 그와 오랜 시간을 함께 한 필자의 추억이다. Kim Junghee, who passed away in sad circumstances in December 2019, was a leading light in the East Coast shaman ritual tradition-an extraordinarily skilled and dedicated man who played a vital role in leading his tradition’s transition from the old world into the new. He was the very last instrumentalist in his troupe to have been born and raised within the region’s hereditary shaman social institution-the last hwaraengi-and, as such, he fostered an identity and approach to artistry forged in a by-gone era. At the same time, he was a major player in opening up the East Coast shamanic arts to a life beyond village ritual. This article looks back over Kim’s rich life and extensive gifts, aiming to piece together a fairly detailed picture of the man and his music. It elucidates the formative factors and processes that shaped his artistry and influenced his path through life, pinpoints his various contributions as a teacher and performer, explores his distinctive personal musical style, and highlights the enormous significance of his passing for the tradition he devoted his life to. To assess these areas, the article draws extensively upon memories gathered by the author between 1999 and 2019-Kim’s own memories, the memories of others within his troupe, and also the author’s own memories of spending time with him.
