The lower Aptian Shuaiba carbonate outcrops in Jebel Akhdar, northern Oman: Impact on static modeling for Shuaiba petroleum reservoirs (2002)

Outcrops in the Jebel Akhdar (north Oman Mountains) offer a unique opportunity to study the depositional architecture of the lower Aptian Shuaiba carbonate that is the main hydrocarbon-producing interval in north Oman. This carbonate formation belongs to an early Aptian platform complex that can be divided into inner- and outer-shelf domains with a sharp transition to the basinal environment toward the north. Detailed outcrop studies were carried out to establish a stratigraphic data set that could be used as an analog for reservoir characterization in the subsurface. High-resolution stratigraphic correlations between as closely spaced as possible sections allow two-dimensional (2-D) geometry of sedimentary bodies to be interpreted within a sequence-stratigraphic framework. The environment restriction and the situation relative to the shelf margin have the greatest impact on the development and geometry of the facies. Inner-shelf rudist beds have a variable thickness (1-10 m) and are laterally continuous (10-45 km). They can be locally interbedded with thin (20 m). For a given facies, overall body thickness is 40% thinner in the inner shelf, whereas body length is 30% shorter in the outer shelf. Interpreted stratigraphic systems tracts, transgressive and regressive, also are characterized by specific facies developments in combination with the paleogeographic situation. Descriptive statistics of the stratigraphic data set are provided. Such basic numerical data can support static modeling of Shuaiba reservoirs in north Oman's main oil fields in relation to the paleogeographic setting and the stratigraphic systems tracts.

Prognosis of remaining bearing life using neural networks (2000)

A new concept referred to as progression-based prediction of remaining life (PPRL) is proposed in the present paper in order to solve the problem of accurately predicting the remaining bearing life. The basic concept behind PPRL is to apply different prediction methods to different bearing running stages. A new prediction procedure which predicts precisely the remaining bearing life is developed on the basis of variables characterizing the state of a deterioration mechanism which are determined from on-line measurements and the application of PPRL via a compound model of neural computation. The procedure consists of on-line modelling of the bearing running state via neural networks and logic rules and not only can solve the boundary problem of remaining life but also can automatically adapt to changes in environmental factors. In addition, multi-step prediction is possible. The proposed technique enhances the traditional prediction methods of remaining bearing life.
Response (2000)

We studied the safety of right-lobe donor hepatectomy in living donors with a positive serological test result for antibody against hepatitis B core antigen (anti-HBc). Of 54 right-lobe living liver donors, serum anti-HBc was positive in 29 donors (54%) and negative in 25 donors (46%). None had a history of hepatitis and all had normal liver biochemistry test results before surgery. Surgical data, postoperative liver function, and outcome of donors were compared according to anti-HBc status. Donors positive for anti-HBc were significantly older (median age, 42 v 31 years; P < .001), but there was no difference in other demographics and liver size. Median blood loss was greater in anti-HBc-positive donors (600 v 350 mL; P = .007). Histological examination showed no difference in degree of portal fibrosis or fatty change in liver grafts. There was no significant difference in postoperative serum transaminase levels or prothrombin times; however, anti-HBc-positive donors had greater serum bilirubin levels day 6 (26 v 21 μmol/L; P = .01) and day 7 (22 v 15 μmol/L; P = .004) after surgery. Postoperative complications developed in 10 anti-HBc-positive and 6 anti-HBc-negative donors (P = .4). All donors who developed cholestasis were positive for anti-HBc, aged 45 years or older, and had mild fatty changes of the liver. Hospital stays were similar. All donors had completely normal liver function at a median follow-up of 31 months (range, 21 to 76 months). A positive serological test result for anti-HBc should not be regarded as a contraindication for right-lobe liver donation. (Liver Transpl 2003;9:827-832.)

CuInS2/ZnS core/shell quantum dots by cation exchange and their blue-shifted photoluminescence (2011)

Highly luminescent CuInS2/ZnS (CIS/ZnS) core/shell quantum dots with a quantum yield of 65% were synthesized by a cation exchange reaction. Similar sized CIS cores and CIS/ZnS core/shells, which were confirmed by TEM, showed that cation exchange occurred inside the core, which reduced the core size and increased the blue-shift in their emission. ICP revealed the CIS cores to have a gradient composition that is richer in indium close to the surface of the core, which explains the broad emission spectrum. This cation exchange reaction could be applied to AgInS2 (AIS) QDs, which showed a blue shift of 70 nm in the emission spectrum. The PXRD pattern also showed a peak shift as evidence of a core/shell structure.
Removal of primary iron rich phase from aluminum-silicon melt by centrifugal separation (2013)

Recycling is a major consideration in continued aluminum use due to the enormous demand for high quality products. Some impurity elements gradually accumulate through the repetitive reuse of aluminum alloy scrap. Of them, the iron content should be suppressed under the allowed limit. In the present research, a novel separation method was introduced to remove primary iron-rich intermetallic compounds by centrifugation during solidification of Al-Si-Fe alloys. This method does not use the density difference between two phases as in other centrifugal methods, but uses the order of solidification in Al-Si-Fe alloys, because iron promotes the formation of intermetallic compounds with other alloying elements as a primary phase. Two Al-Si-Fe alloys which have different iron contents were chosen as the starting materials. The iron-rich phase could be efficiently removed by centrifuging under a centrifugal force of 40 g. Coarse intermetallic compounds were found in the sample inside the crucible, while rather fine intermetallic compounds were found in the sample outside the crucible. Primary intermetallic compounds were linked to each other via aluminum-rich matrix, and formed like a network. The highest iron removal fraction is 67% and the lowest one is 7% for Al-12Si-1.7Fe alloy. And they are 82% and 18% for Al-12Si-3.4Fe alloy, respectively.

An on-line algorithm for dynamic reinforcement learning and planning in reactive environments (1990)

An online learning algorithm for reinforcement learning with continually running recurrent networks in nonstationary reactive environments is described. Various kinds of reinforcement are considered as special types of input to an agent living in the environment. The agent's only goal is to maximize the amount of reinforcement received over time. Supervised learning techniques for recurrent networks serve to construct a differentiable model of the environmental dynamics which includes a model of future reinforcement. This model is used for learning goal-directed behavior in an online fashion. The possibility of using the system for planning future action sequences is investigated and this approach is compared to approaches based on temporal difference methods. A connection to metalearning (learning how to learn) is noted
Development of chitosan-collagen hydrogel incorporated with lysostaphin (CCHL) burn dressing with anti-methicillin-resistant Staphylococcus aureus and promotion wound healing properties (2010)

Methicillin-resistant Staphylococcus aureus (MRSA) have become increasingly prevalent as nosocomial pathogens, especially in burn patients, which is the leading cause of their death. A drug delivery system of chitosan-collagen hydrogel incorporated with lysostaphin (CCHL) based on the lysostaphin gauze was developed for MRSA infected burn wounds. CCHL scaffold consisted of numerous interconnected sphericles and tubular bodies with an average diameter of 100-200 µm, 20-60-fold swelling, high water retention capacity, and cell proliferation properties. The minimal inhibitory concentration of CCHL was 0.053 U/mL. By the second week after its application on MRSA infected third-degree burn wounds, no bacteria could be detected and the burn wounds had started healing. Therefore, CCHL should be studied further as a promising candidate of burn treatment dressing against MRSA infections for clinics.

Immature Forms of the Mite, Caeculus Pettiti (1945)

Vitzthum (1933) described the larva of a new species of mite, Caeculus willmanni, from Guatemala. Both the description and the figure of this larva are so at variance with the appearance of C. pettiti that it was thought worth while to describe and to figure the larva and nymph of the latter species. Jacot (1936) compared some nymphal characters with adult characters for C. laoshanensis, C. sinensis and C. sinensis taishanicus.

World class manufacturing : the lessons of simplicity applied (1986)

In his best-selling book Japanese Manufacturing Techniques, Richard J. Schonberger revolutionized American manufacturing theory and, more important, practice. In that breakthrough book, he revealed that Japanese manufacturing excellence was not culturally bound. Offering the first demystified explanation of the simple techniques that fueled Japan's industrial success, he demonstrated how the same methods could be put to work as effectively in U.S. plants. Now, in World Class Manufacturing, Schonberger returns to tell the success stories of nearly 100 American corporations -- including Hewlett-Packard, Harley-Davidson, General Motors, Honeywell, and Uniroyal -- that have adopted the famed just-in-time production and "total quality control" strategies. Based on his firsthand experience as a major consultant to American industry, he examines how they did it -
Balancing reactors for semiconductor rectifiers (1958)

THE ADVANTAGES of semiconductor diodes in certain applications of d-c power have led to the design and construction of rectifier units of very high current ratings, employing many diodes in parallel on each phase of the rectifier transformer. As in the case of mercury-arc rectifiers having more than one anode connected to each phase, the designer is faced with the problem of current unbalance between parallel elements.
Distribution System Pricing with Distributed Energy Resources (2017)

Technological changes in the electric utility industry bring tremendous opportunities and significant challenges. Customers are installing clean sources of on-site generation such as rooftop solar photovoltaic (PV) systems. At the same time, smart appliances and control systems that can communicate with the grid are entering the retail market. Among the opportunities these changes create are a cleaner and more diverse power system, the ability to improve system reliability and system resilience, and the potential for lower total costs. Challenges include integrating these new resources in a way that maintains system reliability, provides an equitable sharing of system costs, and avoids unbalanced impacts on different groups of customers, including those who install distributed energy resources (DERs) and low-income households who may be the least able to afford the transition.
Differential Effect of Stress on In Vivo Dopamine Release in Striatum, Nucleus Accumbens, and Medial Frontal Cortex (1989)

Microdialysis was used to assess extracellular dopamine in striatum, nucleus accumbens, and medial frontal cortex of unanesthetized rats both under resting conditions and in response to intermittent tail-shock stress. The dopamine metabolites 3,4-dihydroxyphenylacetic acid and homovanillic acid also were measured. The resting extracellular concentration of dopamine was estimated to be approximately 10 nM in striatum, 11 nM in nucleus accumbens, and 3 nM in medial frontal cortex. In contrast, the resting extracellular levels of 3,4-dihydroxyphenylacetic acid and homovanillic acid were in the low micromolar range. Intermittent tail-shock stress increased extracellular dopamine relative to baseline by 25% in striatum, 39% in nucleus accumbens, and 95% in medial frontal cortex. 3,4-Dihydroxyphenylacetic acid and homovanillic acid also were generally increased by stress, although there was a great deal of variability in these responses. These data provide direct in vivo evidence for the global activation of dopaminergic systems by stress and support the concept that there exist regional variations in the regulation of dopamine release.
BLOOD LEVELS OF FSH, LH, TSH, AND GH IN PARKINSONIAN PATIENTS BEFORE AND DURING L-DOPA TREATMENT (1972)

Serum levels of FSH, LH, TSH, and GH were studied in 17 parkinsonian patients before treatment with L-DOPA and in 25 patients during treatment with L-DOPA. A radioimmunosorbent technique was used. With few exceptions the hormone levels were normal in the non-treated patients. No statistically significant differences between the treated and non-treated patients were found.
HLA-A*01 allele: a risk factor for dengue haemorrhagic fever in Brazil's population (2012)

Severe forms of dengue, such as dengue haemorrhagic fever (DHF) and dengue shock syndrome, are examples of a complex pathogenic mechanism in which the virus, environment and host immune response interact. The influence of the host's genetic predisposition to susceptibility or resistance to infectious diseases has been evidenced in several studies. The association of the human leukocyte antigen gene (HLA) class I alleles with DHF susceptibility or resistance has been reported in ethnically and geographically distinct populations. Due to these ethnic and viral strain differences, associations occur in each population, independently with a specific allele, which most likely explains the associations of several alleles with DHF. As the potential role of HLA alleles in the progression of DHF in Brazilian patients remains unknown, we then identified HLA-A alleles in 67 patients with dengue fever and 42 with DHF from Rio de Janeiro, Brazil, selected from 2002-2008 by the sequence-based typing technique. Statistical analysis revealed an association between the HLA-A*01 allele and DHF [odds ratio (OR) = 2.7, p = 0.01], while analysis of the HLA-A*31 allele (OR = 0.5, p = 0.11) suggested a potential protective role in DHF that should be further investigated. This study provides evidence that HLA class I alleles might be important risk factors for DHF in Brazilian patients.
The effect of ultrahigh molecular weight polymers on the nonlinear response in uniaxial elongational viscosity (1997)

We studied the effect of ultrahigh molecular weight (UHMW) polymer on the strain-hardening in uniaxial elongation using PMMA varying UHMW content. These samples were homogeneously blended by solvent casting method. The relation between UHMW components and uniaxial elongational viscosity are discussed.
Introduction Location, Location, Location (2000)

Question: "Why were the Mexicans at the battle of Buena Vista like good wine?" Answer: "Because they both run from the grape." Hardly a distinctive riddle in the wake of the 1848 Treaty of Guadalupe-Hidalgo that closes the U.S.-Mexican War. More surprising, however, is its publishing venue: this anti-Mexican puzzle, reproduced in Eric Lott's 1993 study Love and Theft, is printed at the bottom of a page of lyrics for the song "Why does dat Darkey follow me so?" in the Minstrel Songbook of 1848. If we consider that the popularity of the minstrel show, according to Lott, peaks in 1846, we can read this kind of performance not only as working out the tensions surrounding the slavery question, but as a way of handling the repercussions of the Mexican War as well.1 KeywordsAmerican StudyContinental DivideWestern HistorianBuena VistaAmerican ImperialismThese keywords were added by machine and not by the authors.

Bayesian correction of image intensity with spatial consideration (2004)

Abstract. Under dimly lit condition, it is difficult to take a satisfactory image in long exposure time with a hand-held camera. Despite the use of a tripod, moving objects in the scene still generate ghosting and blurring effect. In this paper, we propose a novel approach to recover a high-quality image by exploiting the tradeoff between exposure time and motion blur, which considers color statistics and spatial constraints simultaneously, by using only two defective input images. A Bayesian framework is adopted to incorporate the factors to generate an optimal color mapping function. No estimation of PSF is performed. Our new approach can be readily extended to handle high contrast scenes to reveal fine details in saturated or highlight regions. An image acquisition system deploying off-the-shelf digital cameras and camera control softwares was built. We present our results on a variety of defective images: global and local motion blur due to camera shake or object movement, and saturation due to high contrast scenes. 1
