Intramolekulare Cycloadditionen in der Reihe der Binaphthyle (1975)

Intramolecular cyloadditions of binaphtyl compounds Three new bridged ketones, 7,8 and 9 , have been isolated in 44%, 3% and 19% yields respectively ( Scheme 2 ) by heating 2,2′‐bis‐allyloxy‐1,1′‐binaphthyl ( 5 ) at 215° for 16 hours. These compounds could be epimerized about C(16) by bases, and in particular 9 yielded the new epimer 10 . The structures of the alcohols obtained by reduction of the keto group are also given ( Scheme 2 ). The constitution of all compounds was derived from spectroscopic data, chiefly from their 1 H‐NMR, spectra (tab. 2, 3 and fig. 1). The assignments were based on the observed long‐range coupling constant between H( endo )‐C(16) and H( endo )‐C(5) in 7 and 10 and on the analysis of chemical shifts and coupling constants in both the ketones and their derivatives. Moreover, the structures of the compounds investigated have been proved by x‐ray analysis of ketone 8 (chap. 3, fig. 2). The thermal conversion of binaphthylether 5 to the bridged ketones proceeds via an intramolecular Diels‐Alder reaction, followed by Claisen rearrangement ( Scheme 8 ). On heating, the bis‐beta‐methylallyl ether 20 yielded the ketone 21 and a small amount of the ether 23 ( Schemes 5 and 7 ). Ether 23 and binaphthyl monoallyl ether 26 were converted thermally to the bridged ketones 31 ( Scheme 7 ) and 27 ( Scheme 6 ) respectively. In addition, 26 underwent an intramolecular ene‐reaction to give the spiroketone 28 ( Schemes 6 and 9 ). The structures of these compounds were also established, mainly by analysis of their 1 H‐NMR. spectra.

Preparation of acetoacetylated wood meal and its properties. Part 1. Preparation of parameter and preliminary evaluation of the antifungal activity (2006)

Abstract Acetoacetylated wood meal (AAWM) was prepared and a preliminary evaluation of its antifungal activity was carried out. Acetoacetylation of wood meal proceeded almost quantitatively with diketene under optimal reaction conditions, even as a heterogeneous reaction. Diketene concentration was the most important governing factor for this reaction. AAWM with a high weight percentage gain inhibited the fungal growth of Fomitopsis palustris .
RF Performance of Diamond Metel–Semiconductor Field-Effect Transistor at Elevated Temperatures and Analysis of its Equivalent Circuit (2006)

Temperature dependent DC and RF characteristics of p-type diamond metal–semiconductor field-effect transistors (MESFETs) on hydrogen-terminated surfaces are investigated. The device is thermally stable up to 100 °C, because it does not deteriorate at all at higher temperatures. Temperature coefficients of transconductance (gm), drain conductance (gds), gate–source capacitance (Cgs), gate–drain capacitance (Cgd), cut-off frequency ( fT), and maximum drain current (Ids) were obtained from small-signal equivalent circuit analysis. The cut-off frequency ( fT) is almost totally independent of temperature. Intrinsic gm, gds, and Cgs decrease with increasing temperature. Cgd is almost totally independent of temperature. The threshold voltage shifts to the negative side with increasing temperature. We propose a band model of an Al-gate contact/H-terminated diamond to explain the temperature dependence of these components.
Familial Congenital Disorder Resembling Stiff-Man Syndrome (1972)

An inherited, congenital disorder resembling stiff-man syndrome is described in ten individuals from three generations of a family. The disease is apparently inherited as a dominant trait; x-linkage cannot be excluded. The diagnosis was based on the following criteria; (1) attacks of stiffness precipitated by surprise or minor physical contact; difficulty in sudden movements but absence of signs of myotonia or myokymia; (2) presence of the electromyographic counterpart of the stiffness, continuous activity at rest with normal action potentials; (3) disappearance of the continuous electrical activity after diazepam. The symptoms were most marked in infancy, but ameliorated with time, becoming milder than in the average acquired case. The cause of this familial syndrome is presumably different from that or those of acquired, sporadic cases of stiff-man syndrome.
Analysis of the Radial Forging Process for Manufacturing Rods and Tubes (1976)

The slab method of analysis was applied to study the mechanics of radial forging of rods and tubes. The analysis has been computerized by taking into account the effects of strain, strain rate, and temperature upon the flow stress of the material being forged. Forging loads were predicted for selected conditions in radial forging of rods at room temperature. The predictions were compared with experimental data, published by another investigator. The results indicate that the analysis developed in the present study is sufficiently accurate for practical purposes. A parametric study was conducted to determine the relations between various process variables in hot radial forging of tubes.
Anomalous head posturing in essential infantile esotropia: a hypothesis (2012)

1This editorial presents our understanding of why a child with infantile esotropia syndrome may manifest a visually directed anomalous head posture (AHP). Many aspects of essential infantile esotropia (EIE) or infantile esotropia syn-drome remain controversial and ill-defined (1). The recent National Eye Institute, National Institutes of Health, USA–sponsored Classification of Eye Movement Abnormalities and Strabismus (CEMAS) workshop and document has at-tempted to consolidate its definition (2). Table I presents the CEMAS description of EIE.Torticollis in childhood is most commonly the result of ab-normalities of the central nervous system, the ocular motor system, or the neck musculature. Head posturing associ-ated with abnormalities of the ocular motor system is usu-ally compensatory. The visual purpose of head posturing serves to enhance bifoveal fixation, singular binocular vi-sion, or visual acuity. The ocular etiologies of anomalous head posture include strabismus, nystagmus, refractive errors, dissociated ocular deviations, and visual pathway obstruction (e.g., lid, corneal, lens, and vitreous anoma-lies). Although clinical differentiation of these disorders is accurately accomplished after a thorough history and ophthalmic examination, the etiology of anomalous head posture is often elusive in patients with a combination of strabismus and nystagmus. Children with nystagmus will have anomalous head posture due to multiple causes. A “gaze null” is a position of one or both eyes with respect to the orbit where the nystagmus intensity is the least and vision is the best and is usually associated with infantile nystagmus syndrome or more rarely, forms of acquired nystagmus with an eccentric gaze null position, e.g., gaze evoked, upbeat, and downbeat nystagmus. An “adduction null” is a position of a preferred eye in adduction charac-
Xeroradiography of the breast. A comparative study with conventional film mammography (1971)

Investigation of xeroradiography as a method of examination of the breast for cancer was begun at Hutzel Hospital, Detroit, in 1966. The procedure appeared to have great promise. The following advantages of xeroradiography over conventional film mammography were: 1. ease of production; 2. ease of interpretation, and 3. clear recording of all densities of the breast on one image. It was believed the method also would prove to be more accurate in diagnosis. A comparative study supported by a USPHS grant was designed and carried out over a 4-year period. Patients having mammography at Hutzel Hospital were doubly examined, although care was taken not to exceed that amount of radiation required for the Egan technique of mammography. With the aid of statisticians, test sets were administered to radiologists in a few large cities in the U.S. Xeroradiography demonstrated a clear superiority in the diagnosis of malignant disease (84.3% xeroradiography vs. 72.2% film, true positive). In benign disease, the two modes were very similar (75.5% xeroradiography vs. 75.0% film, true negative). Xeroradiography was significantly superior in overall accuracy (79.9% xeroradiography vs. 73.6% film). All figures are statistically significant at least at the 5% level or better.
Diversity Opportunities for Higher Education and Honors Programs: A View from Nebraska (2003)

While honors programs were developed in part to actively engage top students in undergraduate education, they also have demonstrated a capacity for leading innovation in post-secondary institutions. Innovations come in the form of curricular development, service learning programs, and independent scholarship. As institutions strive to find effective approaches to improving access to and diversity in higher education, honors programs, in a most general sense, offer a link between diversity and improved access. This paper explores the role of honors programs in expanding access and diversity—an area traditionally focused on broader student populations. Demographic changes in Nebraska, marked by increased ethnic diversity, offer an intriguing example of how honors programs might better embrace diversity.
Information, Complexity and the Detail (2014)

Abstract The proliferation of affordable computing has transformed the capability of architecture to deal with complex forms and details. As Dennis R Shelden , Chief Technology Officer of Gehry Technologies, explains, this has resulted in the production of an abundance of digital information or data. The intersection of two curved surfaces, for instance, is now much more complex than the surfaces themselves. Complexity requires more information and thus more processing, making details like this ultimately more expensive to produce. The jury is still out on what the future might hold, as architecture undergoes a period of fundamental transition in which, for the time being at least, there remains an essential mismatch between the surfeit of digital information and the tight economic limits on physical production.
Dense optical flow by iterative local window registration (2005)

We study dense optical flow estimation using iterative registration of local window, also known as iterative Lucas-Kanade (LK) [B. Lucas et al, 1981]. We show that the usual iterative-warping scheme encounters divergence problems and propose a modified scheme with better behavior. It yields good results with a much lower cost than the exact dense LK algorithm, on simulated and real sequences.

Development of the Basic Core Test Items of National Nurse's License Examination (2004)

The purpose of this study is to develop a classification framework for the test elements of the National Registered Nurse's License Examination and to divide the test items into standard and basic core on the basis of the RN's job descriptions. And the adequa to proportion of the basic core test items is going to be identified. Method and results: In order to develop the classification framework of the National Registered Nurse's License Examination, RN's job descriptions, nursing standards, and the specific learning objectives of nursing courses were reviewed. And a survey was used to identify which entity would be appropriate for a reference to the basic core test items. 146 of professors from schools of nursing and members of each division of Korean Academic Society of Nursing(KASN) were participated in the survey. The study showed the 98% of respondents agreed to use RN's job descriptions in selecting the basic core test items and 30% for the basic core test would be appropriate. And the contents, the selection criteria, and the proportion of the basic core test items were developed by the members of this research, the members of the National RN's License Examination subcommittee, and the presidents of each division of KASN. The total of 1990 standard test items were selected among 3524 items, that 3 out of 7 members in the research team agreed to choose. Duplicated items in the standard items were deleted. 205 items out of the 1990 standard items were selected as the basic core test items. And 14 items were added in Medical Laws and Ethics which leads the total of 219 basic core test items. ln conclusion, the 99 items, 30% of total current examination items were chosen as the final basic core test items using the delphimethod. Further studies are needed to validate the current National License Examination for RN on the basis of the 99 basic core test items.
Selective regulation of Gi alpha 1 expression and function in PC12 cells by cAMP (1992)

Hormone and neutrotransmitter receptor systems regulate both the activity and expression of GTP-binding proteins (G-proteins). However, relatively little is known about the mechanism by which this regulation occurs. One G-protein subtype, Gi alpha 1, is expressed primarily in neuronal cells. Here, we demonstrate the selective regulation of Gi alpha 1 mRNA and protein levels by cAMP. Treatment of PC12 cells with forskolin increases Gi alpha protein levels. Similarly, incubation of PC12 cells with agents that increase intracellular levels of cAMP, including forskolin, dibutyryl-cAMP, and 8-bromo-cAMP, induce a two- to fourfold increase in Gi alpha 1 mRNA levels. Furthermore, the effect of increased intracellular cAMP is specific for Gi alpha 1 mRNA expression; the levels of mRNA encoding other G-protein subtypes remain unaltered. cAMP-stimulated Gi alpha 1 expression occurs within hours of treatment and is sustained for days. Increasing intracellular cAMP by activation of cell surface adenosine receptors also increases Gi alpha 1 mRNA levels. Treatment of PC12 cells with phorbol esters, NGF, or depolarizing concentrations of KCl did not increase Gi alpha 1 mRNA expression, demonstrating that Gi alpha 1 expression is specifically regulated by cAMP. Guanine nucleotide-mediated inhibition of adenylate cyclase activity was measured in order to determine if the change in Gi alpha protein expression was accompanied by a change in G-protein function. Adenylate cyclase activity in PC12 cells treated with an adenosine analog and therefore expressing higher levels of Gi alpha protein is more sensitive to inhibition by guanine nucleotides than in nontreated PC12 cells.(ABSTRACT TRUNCATED AT 250 WORDS)

A Factor Analytic Approach to Inferring Congestion Sharing Based on Flow Level Measurements (2007)

Internet traffic primarily consists of packets from elastic flows, i.e., Web transfers, file transfers, and e-mail, whose transmissions are mediated via the Transmission Control Protocol (TCP). In this paper, we develop a methodology to process TCP flow measurements in order to analyze throughput correlations among TCP flow classes that can be used to infer congestion sharing in the Internet. The primary contributions of this paper are: 1) development of a technique for processing flow records suitable for inferring congested resource sharing; 2) evaluation of the use of factor analysis on processed flow records to explore which TCP flow classes might share congested resources; and 3)validation of our inference methodology using bootstrap methods and nonintrusive, flow level measurements collected at a single network site. Our proposal for using flow level measurements to infer congestion sharing differs significantly from previous research that has employed packet level measurements for making inferences. Possible applications of our method include network monitoring and root cause analysis of poor performance
A new device for the automatic determination of formaldehyde in air (1997)

The development, construction and operation of an intrument for the automatic sampling and analysis of organic pollutants in air is described. The instrument consists of a liquid chromtograph equipped with an autoinjedtor which has been modified to act as a sampling device. Air samples are authomaticallu drawn through the device which contains a suitable reaction liquid. Pollutants are transferred to the liquid and selectively retained. After each sampling step the liquid is injected into the chromatigraphic system and analysed. The sampling conditions for the determination of formadehyde (and acetaldehyde) are discussed.
Cloud motion estimation in SEVIRI image sequences (2009)

Determination of atmospheric dynamic characteristics from remote sensing imagery is fundamental in weather and climate studies. The SEVIRI radiometer, on board the MSG, with its 12 bands and 15 minutes sensing capability provides an important amount of information for cloud tracking. In this work, we have first conducted a detailed evaluation of twelve region matching techniques in order to select those providing the best results. For this performance evaluation, databases of synthetic and real sequences have been used. Next, the best metrics have been incorporated in a new methodology that includes a preliminary stage that segments cloudy structures to initialize the optimum motion estimation parameters (template size and search window dimensions). Also a study region mask is generated to disable the application of the motion estimation algorithm in unreliable areas, thus, eliminating erroneous vectors and decreasing the computation times.
Clinical determinants of severe bleeding complications in patients with acute myocardial infarction treated with thrombolytic therapy (2005)

Introduction Community-acquired pneumonia remains a common condition worldwide. It is associated with significant morbidity and mortality. The aim of this study was to evaluate conditions that could predict a poor outcome. Design Retrospective analyse of 69 patients admitted to the ICU from 1996 to 2003. Demographic data included age, sex and medical history. Etiologic agents, multiorgan dysfunction, nosocomial infections, SAPS II and PORT scores were recorded for each patient. For statistical analysis we used a t test, chi-square test and Mann-Whitney U test on SPSS . A value of P less than 0.05 was considered significant. Results Forty-seven patients were male and 22 patients were female. Mean age was 52 years. Sixty-seven percent had serious pre-morbid conditions including pulmonary disease (34.8%), cardiac problems (36.2%), diabetes (13%) and chronic liver disease (5.8%); 40.6% were smokers, drug abusers or alcohol dependents. Sixtyeight patients required invasive mechanical ventilation. The average length of ventilation was 13.5 days, median 8 days. The mean SAPS II score was 40.14 and the mean PORT score was 141. The mortality rate was 27.5% (SAPS II estimated mortality, 35%). Complications reported were ARDS (40.6%), septic shock (34.8%), acute renal failure (2.9%), cardiac arrest (8.7%) and nosocomial infeccions (46.4%). Mortality rates were higher for previous hepatic (75%) and metabolic (33%) diseases. We found a close association between crude mortality and SAPS II score (P = 0.003) and development of complications (P = 0.0028). Respiratory dysfunction (P = 0.006) and septic shock (P = 0.022) were most significantly related to mortality. No significant differences were founded regarding age, comorbidities, PORT score, etiologic agents, nosocomial infections and length of invasive mechanical ventilation. Conclusions Previous hepatic chronic disease was strictly related to higher mortality as well as isolation of MRSA. ARDS and septic shock predicted a poor outcome. SAPS II score was the best severity indicator of mortality.
The role of alkane dithiols in controlling polymer crystallization in small band gap polymer:Fullerene solar cells (2011)

Abstract The effect of the addition of 1,8‐octanedithiol (ODT) during processing on the microstructure of blend films of poly[2,6‐(4,4‐bis‐(2‐ethylhexyl)‐4H‐cyclopenta[2,1‐b;3,4‐b′]dithiophene)‐ alt ‐4,7(2,1,3‐benzothiadiazole)] (PCPDTBT) and [6,6]‐phenyl‐C 71 butyric acid methyl ester ([70]PCBM) is studied. Grazing incidence X‐ray diffraction and absorption spectroscopy show that the crystalline order of PCPDTBT increases when ODT is introduced in the solution phase either to neat polymer systems or to blends with [70]PCBM. The increased crystalline order is accompanied by less dispersive hole transport in the polymer, and leads to a more efficient formation of a percolating fullerene network within the blend. This contributes to an increase in photocurrent generation. However, the bimolecular recombination rate as determined from photovoltage transients increases upon addition of ODT, limiting the power conversion efficiency to values well below those expected from the energy levels of PCPDTBT. We propose some explanations for this increase in bimolecular recombination, based also on variable angle spectroscopic ellipsometry measurements. © 2011 Wiley Periodicals, Inc.

Data matching for free-surface multiple attenuation by multidimensional deconvolution (2012)

A common strategy for surface-related multiple elimination of seismic data is to predict multiples by a convolutional model and subtract these adaptively from the input gathers. Problems can be posed by interfering multiples and primaries. Removing multiples by multidimensional deconvolution (MDD) (inversion) does not suffer from these problems. However, this approach requires data to be consistent, which is often not the case, especially not at interpolated near-offsets. A novel method is proposed to improve data consistency prior to inversion. This is done by backpropagating first-order multiples with a time-gated reference primary event and matching these with early primaries in the input gather. After data matching, multiple elimination by MDD can be applied with a deterministic inversion scheme.
