An object-oriented organizational model to support dynamic role-based access control in electronic commerce applications (2003)

Role-based access control (RBAC) provides flexibility to security management over the traditional approach of using user and group identifiers. In RBAC, access privileges are given to roles rather than to individual users. Users acquire the corresponding permissions when playing different roles. Roles can be defined simply as a label, but such an approach lacks the support to allow users to automatically change roles under different contexts; this static method also adds administrative overheads in role assignment. In electronic commerce and other cooperative computing environments, access to shared resources has to be controlled in the context of the entire business process; it is therefore necessary to model dynamic roles as a function of resource attributes and contextual information. In this paper, an object-oriented organizational model, OMM, is presented as an underlying model to support dynamic role definition and role resolution in RBAC. The paper describes the OMM reference model and shows how it can be applied flexibly to capture the different classes of resources within a corporation, and to maintain the complex and dynamic roles and relationships between the resource objects. Administrative tools use the role model in OMM to define security policies for role definition and role assignment. At runtime, the resource manager queries the OMM system to resolve roles in order to authorize any access attempts. Similarly, cooperative computing software uses OMM to support task assignment and access control to business processes. Contrary to traditional approaches, OMM separates the organization model from the application model; thus it allows independent and flexible role modeling to reflect realistically a dynamic authorization subsystem in a rapidly changing business world.
Microelectronics design for pollution prevention: a decision tradeoff tool (2002)

After exhausting all "pollution prevention pays" opportunities, further efforts towards environmental protection often engender some type of cost to the manufacturer. Then, designers must weigh tradeoffs between environmental impacts and equally pressing needs to reduce rests, improve product quality and reduce cycle time. This paper presents a computer aid for making these tradeoffs. Qualitative House of Quality (HOQ) information is used as a starting point to derive a mathematical programming formulation for multiobjective optimization. An integer linear program is formulated in a user-friendly spreadsheet. A general formulation of the problem for printed circuit board assembly is provided. The conflicting objectives include cost, size, weight, quality, cycle time, disassembly time and solvent VOC's. The decision variables relate to number of layers, board width, board type and types of components.
Associations Between Oral Conditions and Respiratory Disease in a National Sample Survey Population (1998)

Respiratory infectious diseases such as bacterial pneumonia and bronchitis are common and costly, especially in institutionalized and elderly inpatients. Respiratory infection is thought to rely in part on the aspiration of oropharyngeal flora into the lower respiratory tract and failure of host defense mechanisms to eliminate the contaminating bacteria, which then multiply to cause infection. It has been suggested that dental plaque may act as a reservoir of respiratory pathogens, especially in patients with periodontal disease. However, the impact of poor oral health on oral respiratory pathogen colonization and lung infection is uncertain, especially in ambulatory, non-institutionalized populations. To begin to assess potential associations between respiratory diseases and oral health, data from the National Health and Nutrition Examination Survey I (NHANES I) were analyzed. This database contains information on the general health status of 23,808 individual Of these, 386 individuals reported a suspected respiratory condition that was further assessed by a physician. These subjects were categorized as having a confirmed chronic respiratory disease (chronic bronchitis or emphysema) or an acute respiratory disease (influenza, pneumonia, acute bronchitis). They were compared to those not having a respiratory disease. Initial non-parametric analysis noted that individuals with a confirmed chronic respiratory disease (n = 41) had significantly greater oral hygiene index scores than subjects without respiratory disease (n = 193; P = 0.0441). Logistic regression analysis of data from these subjects, which considered age, race, gender, smoking status, and simplified oral hygiene index (OHI), suggested that subjects having the median OHI value were 1.3 times more likely to have a chronic respiratory disease relative to those with and OHI of O. Similarly, subjects with the maximum OHI value were 4.5 times more likely to have a chronic respiratory disease than those with an OHI of O. No evidence was found to support an association between the periodontal index and any respiratory disease. These results suggest OHI to have a residual effect on chronic respiratory disease of both practical and statistical significance.
Effects of Melatonin on Changes Induced by Castration and Testosterone in Sexual Structures of Male Rats (1970)

The effect of parenteral administration of melatonin on the levels of pituitary LH activity of castrated and castrated, testosterone- treated male rats was studied. The possible direct effect of melatonin on the accessory sex glands, structures well recognized to be under the control of androgenic hormones, was also investigated. Melatonin caused a significant decrease in the weight of the adenohypophyses in castrated rats and also in 1 of the 2 groups of castrated, testosterone-treated male rats. Melatonin also induced significant decreases in ventral prostate weights in both groups of castrated, testosterone-treated rats. Pituitary LH concentration was not significantly affected in any group. Pituitary LH content appeared lower in all groups treated with melatonin. These results suggest a possible direct effect of melatonin on the ventral prostates, which in some way modifies the stimulatory effect of testosterone on these structures.
Technical note: Evaluation of a scoring system for rumen fill in dairy cows (2010)

Changes in feed intake are useful in early detection of disease in dairy cows. Cost and complexity limit our ability to monitor dry matter intake (DMI) of individual cows kept in loose-housing systems. A 5-point subjective scoring system has been developed to visually describe rumen fill, but no work to date has evaluated these scores as an indicator of feed intake. The objective of this study was to evaluate the performance of within-cow changes in visual rumen fill scores as estimates of changes of DMI and feed intake in dairy cows. Our results illustrate that rumen fill scored on a scale from 1 to 5 has substantial intra- (Cohen's kappa coefficient=0.69) and interobserver (Cohen's kappa coefficient=0.68) repeatability. Within-cow changes in visual rumen fill score are correlated with changes in DMI (Spearman's rank correlation=0.68). The depth of the paralumbar fossa (mean +/- SD; 5.6+/-0.9 cm) changes considerably (up to 4.8 cm) within 70+/-5 min. This more objective measure was also correlated with visual rumen fill scores (Spearman's rank correlation=-0.62). Our results indicate that subjective rumen fill scores are statistically associated with both an objective measure of paralumbar fossa indentation and feed intake. However, much of the variation in visual rumen fill scores is not associated with either measure, suggesting that caution is required in clinical usage of these scores.

Fertilization and early embryology: Absence of heat treatment of serum for culture medium supplementation does not adversely affect the outcome of in-vitro fertilization (1994)

This study was carried out to determine if not heat-treating serum prior to use for medium supplementation adversely affected in-vitro fertilization (IVF) of human oocytes. Morphologically mature human oocytes derived from 135 patients undergoing IVF treatment were studied. A total of 504 oocytes were incubated, inseminated and the resulting pronuclear oocytes cultured further in Earle's balanced salt solution (EBSS) supplemented with 10% non-heat-treated serum. Comparisons of fertilization rate and embryonic development were made between these and 687 control oocytes derived from the same patients but incubated, inseminated and resulting pronuclear oocytes cultured further in EBSS supplemented with 10% heat-treated serum. The fertilization rate of 74.4% (375/504) of oocytes handled in serum-supplemented medium that had not been heat-treated was significantly better than the rate of 67.7% (465/687) for controls (P < 0.0125). The proportion of pronucleate oocytes that cleaved was also significantly better in the non-heat-treated serum group: 270/300 (90%) versus 307/375 (81.8%) (P < 0.0025). There was no significant difference in the proportion of embryos with four or more cells at the time of embryo transfer. The results show that the absence of heat treatment of serum used to supplement culture medium has no adverse effect on the fertilization rate and short-term embryo development in vitro; hence we suggest that serum heat treatment is an unnecessary procedure and could be abandoned.
Influence of penicillin on microbial diversity of the cecal microbiota in broiler chickens (2012)

Antibiotic growth promoters have been used for growth promotion of chickens in poultry industry since 1940. Recently, concerns have been raised to the use of antibiotic growth promoters in livestock due to development of antibiotic resistance in bacteria. The objective of our study was to investigate the effect of penicillin supplementation in the feed on cecal microbiota of broiler chickens. Two groups (n = 30) of chickens were fed corn-soybean meal diets with and without supplementation of penicillin at the concentration of 55 mg/kg (ANT vs. CON, respectively). At 18 d of age, the ANT group had significantly (P ≤ 0.05) higher mean BW than the CON group (668.6 vs. 570.0 g). Cecal samples of 5 randomly selected birds were pooled from each group and used for genomic DNA isolation and PCR amplification of 16S rRNA gene; 454 pyrosequencing of the amplicons resulted in 7,881 and 11,214 sequence reads for ANT and CON groups, respectively. Phylogenetic analysis indicated that penicillin supplementation in the ANT group resulted in an elevated proportion of phylum Firmicutes from 58.15 to 91.5% and a decreased proportion of phylum Bacteroidetes from 31.1 to 2.96% compared with the CON group. Recent studies conducted in humans, pigs, and mice have shown a similar shift in gut microbiota in obese individuals compared with the lean ones, indicating that this microbial shift could be responsible for the increase in energy harvest and BW. The results of this study suggest that the growth-promoting effect of penicillin supplementation in broilers may be mediated by a similar microbial process.
Preparation of HCV NS3 and NS5B Proteins to Support Small‐Molecule Drug Discovery (2011)

Production of high-quality, well-characterized recombinant proteins facilitates screening of compound libraries. The protocols detailed in this unit are used to purify three recombinant enzymes that are widely used in HCV research: the HCV NS3 protease domain, the helicase domain as an NS3+NS4A complex, and the NS5B RNA-dependent RNA polymerase. The active enzymes are purified to homogeneity by two-column chromatography to support a screening program for HCV inhibitors.
A Highly Efficient Host/Dopant Combination for Blue Organic Electrophosphorescence Devices (2008)

Abstract We have synthesized a new blue‐emitting iridium complex, FIrpytz (iridium(III) bis(4,6‐difluorophenylpyridinato)‐4‐(pyridin‐2‐yl)‐1,2,3‐triazolate), and two new bis(triphenylsilyl) derivatives, BSB (4,4'‐bis‐triphenylsilanyl‐biphenyl) and BST (4,4″‐bis(triphenylsilanyl)‐(1,1′,4′,1″)‐terphenyl) as hosts for blue phosphorescence devices. The photoluminescence (PL) and electroluminescence (EL) properties of different host/dopant combinations were studied in details. These two arylsilanes showed glass transition temperatures ( T g s) ≥ 100 °C higher than those of UGH1 (diphenyl‐di( o ‐tolyl)silane) and UGH2 (1,4‐bis(triphenylsilyl)benzene), the common arylsilane‐based hosts. The band gaps for BSB and BST are 4.16 and 3.78 eV, respectively, lower than that of UGH2 of 4.40 eV. The FIrpytz‐doped UGH2, BSB and BST films exhibit PL quantum yields of 0.58, 0.83 and 0.48, respectively. The EL devices using FIrpytz or FIrpic (iridium(III) bis(4,6‐difluorophenylpyridinato)‐picolinate) as the blue phosphorescence dopants and UGH2, BSB and BST as the hosts also showed that BSB‐based devices gave the best device efficiencies. Both PL and EL studies show that BSB is better than UGH2 and BST as the host material for FIrpytz and FIrpic. In particular, the use of FIrpytz as dopant, BSB as host and LiF/Al as cathode provides a remarkably efficient combination for blue electrophosphorescence device reaching a very high external quantum efficiency of 19.3% at 8.5 V and a high luminance level of 20500 cd m −2 at 19.3 V after electroluminescence started at 5.1 V.
Promising applications of neodymium boron Iron magnets in electrical machines (1985)

Neodymium Boron Iron (N <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</inf> BF <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">e</inf> ) magnets have high energy product with suitable magnetic and physical properties for applications in electrical machines. The design aspects of permanent magnet machines using NdBFe magnets are presented. The ranges of applications cover both generators and motors up to 200 kW ratings. The exciting combination with micro-computers and power electronics makes the permanent magnet motors truly attractive for drives requiring smooth synchronous operation, constant torque and constant power characteristics.
Colloidal Drop Deposition on Porous Substrates: Competition among Particle Motion, Evaporation, and Infiltration (2015)

Recent interest in printable electronics and in particular paper- and textile-based electronics has fueled research in inkjet printing of colloidal drops on porous substrates. On nonporous substrates, the interplay of particle motion and solvent evaporation determines the final deposition morphology of the evaporating colloidal drop. For porous substrates, solvent infiltration into the pores adds a layer of complexity to the deposition patterns that have not been fully elucidated in the literature. In this study, the deposition of picoliter-sized aqueous colloidal droplets containing nanometer- and micrometer-sized particles onto nanoporous anodic aluminum oxide substrates is examined for different drop and particle sizes and relative humidities as well as pore diameters, porosities, and wettabilities of the porous substrates. For the cases considered, solvent infiltration is found to be much faster than both evaporation and particle motion near the contact line, and thus when the substrate fully imbibes the solvent, the well-known "coffee-ring" deposition is suppressed. However, when the solvent is only partially imbibed, a residual droplet volume exists upon completion of the infiltration. For such cases, two time scales are of importance: the time for particle motion to the contact line as a result of both diffusion and advection, t(P), and the evaporation time of the residual drop volume, t(EI). Their ratio, t(P)/t(EI), determines whether the coffee-ring deposition will be formed (t(P)/t(EI) < 1) or suppressed (t(P)/t(EI) > 1).

Adverse events after naloxone treatment of episodes of suspected acute opioid overdose (2004)

Objective: An increasing and serious heroin overdose problem in Oslo has mandated the increasing out-of-hospital use of naloxone administered by paramedics. The aim of this study was to determine the frequencies and characteristics of adverse events related to this out-of-hospital administration by paramedics. Methods: A one-year prospective observational study from February 1998 to January 1999 was performed in patients suspected to be acutely overdosed by an opioid. A total of 1192 episodes treated with naloxone administered by the Emergency Medical Service system in Oslo, were included. The main outcome variable was adverse events observed immediately after the administration of naloxone. Results: The mean age of patients included was 32.6 years, and 77% were men. Adverse events suspected to be related to naloxone treatment were reported in 45% of episodes. The most common adverse events were related to opioid withdrawal (33%) such as gastrointestinal disorders, aggressiveness, tachycardia, shivering, sweating and tremor. Cases of confusion/restlessness (32%) might be related either to opioid withdrawal or to the effect of the heroin in combination with other drugs. Headache and seizures (25%) were probably related to hypoxia. Most events were non-serious. In three episodes (0.3%) the patients were hospitalized because of adverse events. Conclusion: Although adverse events were common among patients treated for opioid overdose in an out-of-hospital setting, serious complications were rare. Out-of-hospital naloxone treatment by paramedics seems to save several lives a year without a high risk of serious complications.
All-optical NOR gate based on nonlinear photonic crystal microring resonators (2009)

A T-shaped all-optical switch based on nonlinear photonic crystal microring resonator has been analyzed by the finite difference time domain method. Photonic crystal microring resonators are used because they can enhance the nonlinearity due to the localization of light and slow group velocity. By cascading two of these switches we have shown the performance of a NOR gate. The simulations show that in the OFF state the transmission of the proposed NOR gate is only about 2% while in the ON state it is about 81%.
Standard Classifications and Project Numbering System for Integrated Construction Management of Modernized Korean Housing (Hanok) (2012)

A comprehensive research effort in order to develop and disseminate modernized Korean housing (Hanok) has recently been initiated by Korean government. This large scale research project encompasses a wide spectrum of housing development including public policy, architectural plans, modules, construction materials and methods, prefabricated assemblies, automated production, construction management, and advanced information systems. For the purpose of integrating and automating the whole processes from an industry perspective, it is of great importance to develop a standard classification system and project numbering system (PNS) for the modernized Korean housing. This paper focuses on the standard classification systems and PNS for cost and schedule control. The distinct characteristics and managerial requirements were explored and embedded into the proposed classifications for modernized Hanok.
Chinese transnational students and the global education hierarchy (2015)

Recent years have seen a tremendous increase in transnational education mobility. The two trends of international integration and marketisation of higher education have made for a situation in which increasing numbers of aspiring young people worldwide seize the opportunity to study abroad as part of their higher education. No other nation sends more students abroad than China. In 2014, 459,800 students left the country to study abroad (Ministry of Education 2015); and 22 per cent of all international students enrolled in tertiary education in OECD countries in 2012 came from China (OECD 2014: 350). To explore the many dimensions of this huge wave of educational migration we hosted a conference at Aarhus University with the title Chinese Students Abroad: Reflections, Strategies and Impacts of a Global Generation in March 2014. The initial versions of the first three articles in this issue by Heidi Ross and Yajing Chen, Kirsten Jæger and Malene Gram, and Qing Gu were presented at this conference.2 The fourth article, by Naomi Yamada, examines the education of ethnic minorities inside China and thereby throws light on another, but related, effect of the marketisation of Chinese education.
Efficient Support of Statistical Operations (1985)

Most research in statistical databases has concentrated on retrieval, sampling, and aggregation type statistical queries. Data management issues associated with computational statistical operations have been ignored. As a first step towards integrating database management support of statistical operations, we have analyzed the performance of X'X, the QR decomposition, and the Singular Value Factorization. Alternative implementation strategies with respect to the relational and transposed storage organizations are developed. Implementation strategies corresponding to vector building block, vector-matrix, and direct algorithms with explicit buffer management are compared in terms of efficiency in performance.
CpG island methylator phenotype is an independent predictor of survival benefit from 5-fluorouracil in stage III colorectal cancer. (2003)

CIMP+ has independent predictive significance for the survival benefit from 5-FU chemotherapy in CRC. This molecular marker should be incorporated into prospective clinical trials of fluorouracil-based therapies to confirm its clinical value.
High-power laser performance of a-cut and c-cut Yb:LuVO_4 crystals (2006)

We report high-power laser operation that was achieved with a-cut and c-cut Yb:LuVO(4) crystals. Up to 8.3 W of pi-polarized output power was generated from an a-cut, 2 mm uncoated crystal with an optical conversion efficiency of 59%. The highest slope efficiency was 80%. Laser oscillation obtained with c-cut crystal was also linearly polarized, with two orthogonal polarization components along [110] and [(-)110] directions. The highest output power achieved was 4.5 W, with an optical conversion efficiency of 33% and a slope efficiency of 40%.
Hyperphagia by self- and xeno-cannibalism: Cell death by indigestion? A reminiscence of the Phedrus Fabula “Rana Rupta et Bos”? (2008)

The occurrence of self- and xeno-cannibalism could be considered as two different aspects of the same well-regulated process. The formation of autophagosomes can represent a survival option for a cell in unfavorable conditions but it can also lead to cell demise. In fact, autophagy has been considered as an additional and clear-cut cell death pathway. We herein speculate that selfeating by autophagy could be paralleled by a cannibalistic behavior, e.g., by cell feeding of siblings, that can also become detrimental. This behavior in fact, once exacerbated, can also lead to cell death, probably bolstering intracellular oxidative imbalance. In this case, a survival option, such as self- and xeno-cannibalism, can be turned into a peculiar death option: cell death by feeding excess. Under this point of view, over-feeding cells are reminiscent of the frog in the Phedrus Fabula "Rana Rupta et Bos".
Deriving temperature and age appropriate heart rate centiles for children with acute infections (2008)

Age-specific centile charts of heart rates expected at different temperatures should be used by clinicians in the initial assessment of children with acute infections. The charts will identify children who have a heart rate higher than expected for a given temperature and facilitate the interpretation of changes in heart rate on reassessment. Further research on the predictive value of the centile charts is needed to optimise their diagnostic utility.
