High-Quality ZnO Layers Grown on 6H-SiC Substrates by Metalorganic Chemical Vapor Deposition (2004)

In this letter, the 6H-SiC substrate has been studied for the growth of the ZnO layer. The X-ray diffraction measurement clearly showed the c -axis oriented growth of ZnO layers on SiC(0001) substrates. The X-ray rocking curve measurement diffracted a smaller full-width at half maximum of the ZnO layers grown on SiC than that of the same layers grown on the conventional Al 2 O 3 substrate with metalorganic chemical vapor deposition (MOCVD). A distinct free-exciton emission was dominantly observed even at room temperature (RT) while the donor-bound-exciton peaks were disappeared at around ∼120 K. In addition, no deep-level emission was observed even at RT in the ZnO/SiC samples. These optical and crystalline properties have hardly been observed in the ZnO/Al 2 O 3 samples grown by MOCVD. Therefore, the higher quality of the ZnO layers grown on SiC might be attributed to the smaller lattice mismatch of ∼5% as well as the +c surface orientation in ZnO/SiC sample geometry.

Estimating Increases in Skin Cancer Morbidity Due to Increases in Ultraviolet Radiation Exposure (1983)

It is generally accepted that if ozone levels in the stratosphere are depleted, greater amounts of shortwave ultraviolet radiation (UVB) will reach the earth's surface, resulting in increased morbidity of nonmelanoma skin cancer. The incidence and UVB data are now available from a new epidemiologic study of skin cancer conducted at eight locations of the United States. We found that either a simple power function or a simple exponential function could be used to describe these new data. According to estimates based on the power model, should the amount of exposure to UVB increase by 30%, then the incidence of skin cancer will increase by 60% in males and 45% in females. Estimates based on the exponential model vary by location, (53-96)% in males and (39-68)% in females. These estimates are somewhat lower than those based only on earlier data. We emphasize that skin cancer rates also depend on variables other than UVB which may be location specific.
Balance in Personal Care Home Residents (2005)

Results indicate residents of personal care homes are at high fall risk. The balance tests showed moderate to good reliability for this population. The BBS and MDRT appear to be valid measures of motor ability to maintain balance, while the self report ABC appears to measure a different component of the balance construct in this population.
A Synchronous Context Free Grammar for Time Normalization (2013)

We present an approach to time normalization (e.g. <i>the day before yesterday</i>⇒2013-04-12) based on a synchronous context free grammar. Synchronous rules map the source language to formally defined operators for manipulating times (FindEnclosed, StartAtEndOf, etc.). Time expressions are then parsed using an extended CYK+ algorithm, and converted to a normalized form by applying the operators recursively. For evaluation, a small set of synchronous rules for English time expressions were developed. Our model outperforms HeidelTime, the best time normalization system in TempEval 2013, on four different time normalization corpora.
Stimulus-specific Induction of a Novel Nuclear Factor-κB Regulator, IκB-ζ, via Toll/Interleukin-1 Receptor Is Mediated by mRNA Stabilization (2004)

We have recently identified an inducible nuclear factor-kappaB (NF-kappaB) regulator, IkappaB-zeta, which is induced by microbial ligands for Toll-like receptors such as lipopolysaccharide and the proinflammatory cytokine interleukin (IL)-1beta but not by tumor necrosis factor (TNF)-alpha. In the present study, we examined mechanisms for stimulus-specific induction of IkappaB-zeta. The analysis of the IkappaB-zeta promoter revealed an essential role for an NF-kappaB binding sequence in transcriptional activation. The activation, however, did not account for the Toll-like receptor/IL-1 receptor-specific induction of IkappaB-zeta, because the promoter analysis and nuclear run-on analysis indicated that its transcription was similarly induced by TNF-alpha. To examine post-transcriptional regulation, we analyzed the decay of IkappaB-zeta mRNA, and we found that it was specifically stabilized by lipopolysaccharide or IL-1beta but not by TNF-alpha. Furthermore, we found that costimulation with TNF-alpha and another proinflammatory cytokine, IL-17, elicited the IkappaB-zeta induction. Stimulation with IL-17 alone did not induce IkappaB-zeta but stabilized its mRNA. Therefore, IkappaB-zeta induction requires both NF-kappaB activation and stimulus-specific stabilization of its mRNA. Because IkappaB-zeta is essential for expression of a subset of NF-kappaB target genes, the stimulus-specific induction of IkappaB-zeta may be of great significance in regulation of inflammatory reactions.
Fracture Dislocation of the Cervical Spine (1978)

Twenty surgically treated cases of fracture dislocation of the cervical spine are presented. All patients had hyperflexion injuries with associated rupture of the intervertebral disc. All patients were operated on through an anterior surgical approach. Ten consecutive patients had interbody fusion with autogenous bone and ten consecutive patients were fused anteriorly with bovine (Kiel) bone. All patients' injuries fused satisfactorily. There was no significant difference between the use of autogenous bone and bovine bone.
Sex Cord-Gonadal Stromal Tumor of the Rete Testis (2008)

A 34-year-old tetraplegic patient with suppurative epididymitis was found on follow-up examination and ultrasonography to have a testicular mass. The radical orchiectomy specimen contained an undifferentiated spindled sex cord-stromal tumor arising in the rete testis. Testicular sex cord-stromal tumors are far less common than germ cell neoplasms and are usually benign. The close relationship between sex cords and ductules of the rete testis during development provides the opportunity for these uncommon tumors to arise anatomically within the rete tesis. This undifferentiated sex cord-stromal tumor, occurring in a previously unreported location, is an example of an unusual lesion mimicking an intratesticular malignant neoplasm.
Transferencia intraeuropea de la sede de dirección de la empresa, derecho privado, fiscalidad y libertad de establecimiento: comentario a la STJUE (Gran Sala) de 29 de noviembre de 2011, Asunto C-371/10, National Grid Indus BV e Inspecteur van de Belastingdienst Rijnmond/kantoor Rotterdam (1) (2012)

En la sentencia National Grid, el TJUE reconoce que la regulacion de los Estados miembros sobre el traslado al extranjero de la sede de direccion efectiva de las sociedades constituidas de acuerdo con su derecho debe ajustarse a las exigencias de la libertad de establecimiento. Admite, sin embargo, que las restricciones derivadas de la normativa fiscal podrian estar justificadas. En concreto, permite que con ocasion del traslado se graven las plusvalias latentes de la sociedad, aunque entiende que no cabe exigir el pago inmediato de la tributacion que resulte de tales plusvalias.
Data quality: a rising e-business concern (2000)

Data quality has become a business-critical issue because it can make or break the databases and data warehouses that drive e-business. Garbage in, garbage out is not new; it started to become more important because of data warehouses and data marts as well as the Web. In recent InformationWeek surveys, IT professionals have consistently ranked data quality tasks as the leading IT challenge in the post-Y2K remediation era. What's also new is that data quality issues aren't limited to individual erroneous records: they now include how applications associate various pieces of data, and how users use or interpret data. As new data usage revealed the need to ensure data consistency throughout the enterprise, new tools have emerged to help IT reconcile data inconsistencies. Not all professionals are confident off-the-shelf solutions can flexibly meet their needs, but vendors argue that automating tasks allows quicker, cost-effective project and application deployment.

Dynamic Analysis of Risers and Caissons by the Element Method (1976)

ABSTRACT The finite element formulation leads to an efficient and accurate solution for the dynamic response of caissons and risers. The governing equations are derived including intermediate ball joints with nonlinear stiffness, periodic excitation due to surface vessel surge, sway and heave motion, the hydrodynamic excitation of a periodic wave, and multidirectional current. Parametric results based on the method are presented-with emphasis on a deep water riser design having distributed buoyancy material. Or-particular interest is the sensitivity of bending stresses near the bottom of the-riser to periodic top surge and wave forces and the importance of maintaining adequate tension. INTRODUCTION The diminishing unit cost, over the past decade, of high speed mass storage digital computer capability has encouraged the wide spread use of the finite element method. Whereas the early structural analysis computer programs were simply computerized versions of techniques previously performed by hand, the stiffness method of finite element analysis became practical only through implementation on digital computer. The melding of the method and the tool has been so successful that the finite element stiffness method has virtually eclipsed all others for large scale structural analysis. Although several finite element riser programs are known to have been developed, formulation of the riser analysis problem by this method has not yet appeared in the published literature. Over the years, riser design analysis has received considerable attention. Early investigations of riser structural analysis [1, 2] provided the insight necessary for successful design of shallow water risers. More recently, Burke [3] studied riser response sensitivity to the frequency content of the excitation by developing a linearized method of riser dynamic analysis in the frequency domain. This approach has particular value in establishing riser fatigue life. In a series of articles' still being published, Morgan [4, 5] has discussed numerous problems relating to the environment, analysis, and design criteria of marine risers with particular emphasis on deep water. The objective of this paper is to add to the published literature a reasonably complete. Formulation of the riser dynamic response problem by the finite element method. Questions relating to environmental excitation are given only cursory attention. For example, a periodic wave is mentioned as the source of excitation. A more appropriate description of deep sea environment, however, is a random, multi-directional sea state. Methods have been demonstrated in the literature [6, 7] for converting such a random spectral definition to a time history excitation which can be employed in nonlinear dynamic analysis. Similarly, the method described in the next section could be readily converted to linearized, frequency domain methods. Such extensions, and others, are left fox subsequent efforts. MATHEMATICAL MODEL Basic Assumptions Before embarking on the theoretical development it is appropriate to establish the underlying assumptions.

THE LUPUS ANTICOAGULANT/ANTIPHOSPHOLIPID SYNDROME (1996)

Lupus anticoagulants and anticardiolipin antibodies have been strongly associated with the risk of thrombosis, recurrent fetal loss, thrombocytopenia, and a number of other clinical manifestations that together have been referred to as the antiphospholipid syndrome. Despite growing evidence of the significance of this relationship, the pathogenetic mechanisms involved are largely unknown. Recent data suggest strongly that lupus anticoagulants (LACs) and anticardiolipin antibodies (ACAs) are antibodies to protein-phospholipid complexes rather than to phospholipids, as had originally been thought, and that other protein-phospholipid complexes, not recognized by standard assays for LACs or ACAs, may also exist in patients with the antiphospholipid syndrome. Although very recent experimental data may lead to new therapeutic approaches in this syndrome, at present we can only deal with the thrombotic risk by the use of long-term anticoagulation. This chapter reviews current methods of diagnosis, concepts of pathogenesis, and the basis for an approach to anticoagulation in patients at risk for thrombosis or other manifestations of the antiphospholipid syndrome.
Airplane Recognition and Location On the Airport Based On Computer Vision (2016)

In order to improve safety for airliner ground movement at the airport, a positioning method which can identify airliner and find the location of the airliner when the airliner taxiing at the airport based on computer vision is presented. Deep learning method is applied to recognize an airliner from complicated background of an image. After that, image segmentation based on graph is used to acquire the outline of the airliner. Then, after obtaining the nose undercarriage tyre, the location of airliner is obtained by means of coordinate transformation. The simulation results illustrate the validity of the proposed method.
Effects of neutron irradiation on Nd-Fe-B magnetic properties (1988)

Nd-Fe-B permanent magnets from two different manufacturers were irradiated in the Omega West reactor at Los Alamos National Laboratory, with fast neutrons at temperatures of 426 K (153 degrees C) and 350 K (77 degrees C) to fluences of 5.0*10/sup 16/ N/cm/sup 2/ and 6.1*10/sup 16/ N/cm/sup 2/, respectively. At intervals during the irradiation the samples were removed from the reactor and the remanence measured at room temperature. The initial loss of remanence for irradiation at 426 K was 10% for a fluence of 10/sup 15/ N/cm/sup 2/. At 350 K the initial loss rate was roughly half this value. The loss rates were nearly the same for samples from the two different manufacturers. These losses are due to the irradiation since the remanence does not decay with annealing at 426 K. Remagnetization after irradiation results in full recovery of the remanence and roughly a 20% increase in the coercivity. Evidence from this experiment suggests that the primary mechanism for loss of remanence is nucleation of reverse domains by the collision cascade and subsequent growth into the original domain.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
To ECC or Not to ECC: The Question Remains (2008)

The usefulness of endocervical curettage (ECC) in evaluating women who have abnormal cervical cytology and histopathology has been debated for years; data regarding performance of ECC in the diagnostic evaluations of squamous and glandular lesions are mixed. There are no well-done randomized trials or systematic reviews regarding the usefulness of ECC. The yield on ECC increases in the setting of unsatisfactory colposcopy; in this situation, there seems less controversy regarding performance of an ECC. Reproducibility of ECC-rendered diagnosis is a concern. Data are needed to further define the role of ECC in evaluating women who have cervical disease.
Vibrational predissociation spectra of the Ar-tagged [CH<sub>4</sub>· H<sub>3</sub>O<sup>+</sup>] binary complex: spectroscopic signature of hydrogen bonding to an alkane (2010)

Vibrational predissociation spectra of the Ar-tagged [H3O+ ⋅ X], X = CH4, CD4, N2, and Ar complexes are analysed to explore the hydrogen bonding acceptor properties of an alkane. The observed red shift in the OH stretching transition of the donor is found to be significantly smaller than anticipated by the previously reported trend in this value with the proton affinity of the acceptor [Science 316, 249 (2007)] 1 Roscioli, JR, McCunn, LR and Johnson, MA. 2007. Science, 316: 249[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]. Specifically, the alkane-induced red shift of the OH stretching frequency is less than that caused by the conventional proton acceptor, N2, even though the latter is a weaker base than methane. The origin of this effect is discussed in the context of the structures of the complexes and the molecular rearrangements required for complete proton transfer to hydrocarbons as opposed to the situation in conventional H-bond acceptors.
INVESTIGATION OF THE ($alpha$,n) REACTION IN OXYGEN (1957)

Studies were made to determine which isotope (O/sup 17/ or O/sup 18/) has a larger yield of neutrons and to determine the cross section for it. The gamma radiation accompanying the reaction was also investigated. Results of measurements showed that the thick target of O/sup 18/ yields 31 neutrons per 10/ sup 8/ alpha particles, and the cross sections of the reaction ction of any other element except Be.

A Highly Efficient Multifunctional Tandem Affinity Purification Approach Applicable to Diverse Organisms (2012)

Determining the localization, binding partners, and secondary modifications of individual proteins is crucial for understanding protein function. Several tags have been constructed for protein localization or purification under either native or denaturing conditions, but few tags permit all three simultaneously. Here, we describe a multifunctional tandem affinity purification (MAP) method that is both highly efficient and enables protein visualization. The MAP tag utilizes affinity tags inserted into an exposed surface loop of mVenus offering two advantages: (1) mVenus fluorescence can be used for protein localization or FACS-based selection of cell lines; and (2) spatial separation of the affinity tags from the protein results in high recovery and reduced variability between proteins. MAP purification was highly efficient in multiple organisms for all proteins tested. As a test case, MAP combined with liquid chromatography-tandem MS identified known and new candidate binding partners and modifications of the kinase Plk1. Thus the MAP tag is a new powerful tool for determining protein modification, localization, and interactions.
From physics to pharmacology? (2010)

Over the last fifty years there has been an explosion of biological data, leading to the realization that to fully explain biological mechanisms it is necessary to interpret them as complex dynamical systems. The first stage of this interpretation is to determine which components (proteins, genes or metabolites) of the system interact. This is usually represented by a graph, or network. The behavior of this network can then be investigated using mathematical modeling. In vivo these biological networks show several remarkable (and seemingly paradoxical) properties including robustness, plasticity and sensitivity. Erroneous behavior of these networks is often associated with disease. Hence understanding the system-level properties can have important implications for the treatment of disease. Systems biology is an organized approach to quantitatively describe and elucidate the behavior of these complex networks. This review focuses on the progress and future challenges of a systems approach to biology.
Hysteroscopic findings in women with primary and secondary infertility due to genital tuberculosis (2008)

Genital tuberculosis causes significant pelvic morbidity due to uterine adhesions and infertility.
General methods for flash chromatography using disposable columns (2009)

As technology has evolved available guidelines for normal-phase flash chromatography have become less relevant. Years of experience performing chromatography with disposable columns have been condensed into simple guidelines useful for translating TLC results into either isocratic- or gradient-flash chromatography. The described studies should provide researchers with a means of selecting adequate columns and guidelines to reduce the waste of solvents, silica, time, and money.
A Queue-based Adaptive Polling Scheme to Improve System Performance in Gigabit Ethernet Networks (2007)

Gigabit Ethernet is now finding wider deployment in computer networks. The conventional operating system suffers from the receive livelock problem in Gigabit Ethernet networks. The device hybrid (interrupt + polling) scheme has been widely used to overcome this problem in current operating systems such as GNU/Linux and FreeBSD. However, controlling the polling time without regard to the system state can degrade the ability of a hybrid scheme in some situations. This paper focuses on the system performance of the operating systems that employ the device hybrid scheme in kernel space. A queue-based adaptive polling (QAPolling) scheme is introduced that: (1) significantly improves system goodput and reduces packet loss over a wide range of computer hardware configurations and traffic conditions, (2) is scalable and easily deployed. The key idea behind QAPolling is to adjust the polling time adaptively according to the information of the application receiving queues, which are in kernel space and change with the system state, instead of the packet arrival rate. We validate our design through experimental results in Gigabit Ethernet networks.
Aluminium in Groundwater Possible Solution Equilibria (1981)

Recent investigations in the west coast region of Sweden has revealed the occurrence of groundwaters with a pH of around 4 and, further, alarmingly high concentrations of soluble aluminium. The reason for the occurrence of acid groundwater is, of course, the acid precipitation falling over this area of Sweden in combination with coarse soils on resistant types of granites and gneisses. The »resistance« against acidification of groundwater offered in the soil profile by aluminium and iron hydroxides must obviously have been partly broken. It seems therefore relevant to examine the solubility conditions of aluminium compounds in soils and rocks. From this we may reconstruct the process which led to the present state and we may also be able to tell what information on soils is needed in order to predict the future acidification of groundwater.
