Identifying critical traffic jam areas with node centralities interference and robustness

We introduce the notions of centrality interference and centrality robustness, as measures of variation of centrality values when the structure of a network is modified by removing or adding individual nodes from/to a network. Centrality analysis allows categorizing nodes according to their topological relevance in a network. Thus, centrality interference analysis allows understanding which parts of a network are mostly influenced by a node and, conversely, centrality robustness allows quantifying the functional dependency of a node from other nodes in the network. We examine the theoretical significance of these measures and apply them to classify nodes in a road network to predict the effects on the traffic jam due to variations in the structure of the network. In these case the interference analysis allows to predict which are the distinct regions of the network affected by the function of different nodes. Such notions, when applied to a variety of different contexts, opens new perspectives in network analysis since they allow predicting the effects of local network modifications on single node as well as global network functionality.
Anticoagulation in Continuous Renal Replacement Therapy: Citrate Appears to Be Superior to Heparin!

894 www.pccmjournal. org September 2016 • Volume 17 • Number 9 unable to use pRIFLE because patient heights were documented in less than 10% of the patients in the study, and as such were unable to use pediatric eGFR equations. Although Slater et al (14) did not discuss why they chose RIFLE over KDIGO, they did conduct a post hoc analysis, which shows that the KDIGO definition would have only resulted in a 0.3% increase (14 patients out of over 3,800) in the overall incidence of AKI. We agree that it is a worthwhile goal for the AKI research community to agree on a single AKI definition and we agree with Fortenberry et al (13) about the use of the KDIGO AKI criteria, but does the use of RIFLE over KDIGO alter the conclusions of the Slater et al (14) article that the use of nephrotoxic medications is a significant risk factor for the development of AKI? We think not. Instead, we think that the results of this article should heighten the awareness of using nephrotoxic medications in critically ill children. As Slater et al (14) demonstrate, there are risk factors that clinicians can modify to reduce the risk of AKI, and we should focus on prospectively identifying the impact of such factors on the development of AKI.
Analysis of shielded coupled microstrip line with partial dielectric support

A shielded coupled microstrip line with partial dielectric support is analysed using the hybrid boundary element method (HBEM) and the finite difference method (FDM). The HBEM is a combination of the equivalent electrodes method (EEM) and the boundary element method (BEM). The microstrip line characteristic parameters: the effective relative permittivity and the characteristic impedance are determined. “Odd” and “even” modes are taken into account. The results are compared with corresponding ones found in the literature.
A primer on using in ovo electroporation to analyze gene function

The chicken embryo has served as a classic model system for developmental studies due to its easy access for surgical manipulations and a wealth of data about chicken embryogenesis. Notably, the mechanisms controlling limb development have been explored best in the chick. Recently, the method of in ovo electroporation has been used successfully to transfect particular cells/tissues during embryonic development, without the production or infectivity associated with retroviruses. With the sequencing of the chicken genome near completion, this approach will provide a powerful opportunity to examine the function of chicken genes and their counterparts in other species. In ovo electroporation has been most effectively used to date for ectopic or overexpression analyses. However, recent studies indicate that this approach can be used successfully for loss‐of‐function analyses, including protein knockdown experiments with morpholinos and RNAi. Here, I will discuss parameters for using in ovo electroporation successfully to study developmental processes. Developmental Dynamics 229:433–439, 2004. © 2004 Wiley‐Liss, Inc.
ACU improvement of CCT-tunable LED device by electrospun nanofiber film

We fabricated PMMA nanofiber composite diffusion films to improve the angular color uniformity (ACU) of correlated-color-temperature-tunable light emitting diode (CCT-tunable LED) device. Based on electrospinning technology, we prepared diffusion films with different scattering properties by controlling the fiber deposition time. Detailed optical measurement shows that the scattering intensity of PMMA nanofiber films increases with the increase of thickness. The diffuse transmittance and haze are 88%, 96.6% in the visible light, respectively. Furthermore, when applied to the CCT-tunable LED device, the device witnesses a reduced CCT deviation from 630 K to 159 K in a typical CCT range of 5000– 6000 K. Therefore, the proposed nanofiber films can be applied to lighting systems as diffusion films to improve their ACU.
Optimized decimation filter architecture for 5th order ΣΔ converter in GSM/ UMTS/ Wi-max radio receiver

This paper presents an efficient design of a decimation filter for a continuous-time (CT) complex lowpass SigmaDelta modulator in multi-standard receiver. The proposed architecture fulfills the requirements of three standards: Wi-max, UMTS and GSM. The optimization of the proposed decimation structure leads to two implementation architectures which are optimized in different ways: area (in terms of used resources) and power consumption for the required throughput. Experimental results illustrate the high-speed data throughput and low-power consumption features of the proposed designs.
The ICT standardisation policy of the EU: changes ahead!?

The paper first briefly discusses the current situation in the field of ICT standardisation, with a certain focus on Europe. Here, the perceived diminishing influence of Europe in the international standards arena has led to first (minor) initiatives by the European Commission, aiming at changes in their ICT standardisation policy. Some options currently under discussion are addressed.
Regulation of Ti plasmid virulence genes by a chromosomal locus of Agrobacterium tumefaciens

We isolated a mutant strain of Agrobacterium tumefaciens, designated Ros, that has a pleiotropic phenotype which includes elevated levels of expression of certain genes in the virulence (Vir) region of tumor-inducing plasmid pTiC58. This mutant and others were isolated by fusing the promoter of the Vir bak gene to a promoterless gene (cat) that encodes chloramphenicol acetyltransferase and then selecting for increased expression of cat in A. tumefaciens. The ros mutation is chromosomal in nature and is characterized by a more-than-300-fold increase in the level of expression of bak and a 12-fold increase in the level of expression of an adjacent divergent operon containing the hdv genes, which are involved in some aspect of host specificity. The Ros mutant is fully virulent and is typified by its unusual colony morphology; the colonies have rough surfaces, uneven edges, and a pit in the center at 24 degrees C and vary markedly in appearance from one growth temperature to another. The Ros mutant is not able to form colonies at 12 degrees C, a temperature at which the wild-type strain forms colonies in 14 days. The ros mutation occurs spontaneously with a frequency of 5 X 10(-8). Genetic and biochemical evidence indicates that the product of the ros locus is a negative regulator of Ti plasmid genes and is related to undefined chromosomally encoded functions that are involved in the mutant phenotype.
Applications of Defect Prevention in Software Development

A description is given of the defect prevention process. It consists of causal analysis meetings to identify the root causes of errors and suggest preventive actions, an action team that implements the preventive actions, stage kickoff meetings to provide feedback to developers at each stage of the development cycle, and data collection and tracking of associated data. Typical preventive actions include process changes (including common error lists, checklists, and other forms of feedback), new or improved tools, improved education, product changes, and improved communications among developers. The defect prevention process has been applied successfully in a number of software development organizations within IBM, with significant reduction in errors. The application of this process to different types of organizations involved in software development, including design, development, test, information development, planning and requirements, and human factors is described. For each type of organization, different processes, tools, and methodologies are used. It is shown that the defect prevention process can be applied to errors arising from each particular process. >
PREVALENCE OF ASTHMA AND RELATED SYMPTOMS IN SCHOOL-AGED CHILDREN IN ZARINSHAHR, IRAN

Background: Information on the magnitude of the problem of childhood asthma in rural areas of Iran and the factors influencing its occurrence is inadequate. This study was carried out to measure the prevalence of asthma among schoolaged children in Zarinshahr and factors, which determine its occurrence. Materials and Methods: A questionnaire-based study carried out in 33 randomly selected school classes in Zarinshahr. The age of participants ranged from 6 to 13 years. Results: Overall, 1309 questionnaires were returned. The prevalence rates of asthma diagnosed previously, asthma ever in life, current asthma, nocturnal symptoms and exercise induced cough were1.2%, 14.7%, 5.9%, 11.3%, and 19.4%, respectively. Allergic rhinitis and allergic chronic cough were presented in 1.9% and 2.4% of the children. Conclusion: A positive family history of similar disorder, early childhood respiratory infection, paternal smoking and keeping cats at home were significant factors influencing the development of asthma, while children’s gender and parental education
Auxiliary liver transplantation with portal arterialization in the rat: description of a new model

In recent years, portal arterialization has been used in liver transplantation to increase the portal flow, as a solution for singular technical problems. We have developed a new auxiliary liver transplantation model in the rat with portal arterialization, so the native hepatic hilium remains untouched, consisting on a graft with a previous 70% hepatectomy. It is sited on the right renal bed, joining the infrahepatic inferior vena cava (IVC) of the graft with the recipient IVC. With an abdominal aortic graft, we connect the recipient aorta with the portal vein from the auxiliary liver. All the animals survived at the seventh day. No thrombosis was seen in any graft and an important rejection was observed in all the fields. We have developed a new experimental model of an auxiliary liver with portal arterialization, avoiding the utilisation of the native hepatic hilium, necessary for the possible recovering of the proper liver in the case of a reversible fulminant hepatitis. © 2002 Wiley‐Liss, Inc.

Development and Evaluation of Korean Nurses’ Core Competency Scale (KNCCS)

Purpose: The purpose of this study was to develop and evaluate a Korean Nurses’ Core Competency Scale (KNCCS). Methods: This methodological research was conducted over two major steps. The first step involved developing a preliminary 70-item KNCCS based on an extensive literature review and the standards and criteria proposed by the Korean Accreditation of Nursing. The second step involved evaluating validity and reliability of the KNCCS. 528 newly graduated nurses recently employed in nine major hospitals were participated in this research for validation. Results: The final KNCCS consisted of 70 items. The exploratory factor analysis identified five subscales under which each item could be categorized: 1) human understanding and communication skills; 2) professional attitudes; 3) critical thinking and evaluation; 4) general clinical performance; and 5) specific clinical performance. Conclusion: The KNCCS shows good reliability and validity. However, the test of both criterion and construct validity were recommended further.
cDNA Expression Array Analysis of DNA Repair Genes in Human Glioma Cells that Lack or Express DNA-PK1

Abstract Galloway, A. M. and Allalunis-Turner, J. cDNA Expression Array Analysis of DNA Repair Genes in Human Glioma Cells that Lack or Express DNA-PK. M059J cells provide the only example of DNA-PKcs (now known as PRKDC) deficiency in a human cell line. M059K cells, derived from the same tumor specimen, express PRKDC protein and activity and, together with M059J, provide a useful model in which to study the role of DNA-PK in cellular responses to DNA-damaging agents. Because these cells are of tumor origin, we used Atlas™ human cancer cDNA expression arrays to investigate possible differential expression of other DNA repair genes in control and irradiated samples. cDNA array results indicated differential expression of 14 genes. Northern blotting confirmed relatively greater expression of replication factor C 37-kDa subunit mRNA in M059J cells compared to M059K cells and reduced expression of DNA ligase IV compared to ligase III in both cell lines independent of irradiation. These results suggest that other DNA repair proteins are altered in these cell lines and that repair mechanisms predicted from the study of normal tissues may be fundamentally altered in human cancer cells.
Inductive Representation Learning in Large Attributed Graphs

Graphs (networks) are ubiquitous and allow us to model entities (nodes) and the dependencies (edges) between them. Learning a useful feature representation from graph data lies at the heart and success of many machine learning tasks such as classification, anomaly detection, link prediction, among many others. Many existing techniques use random walks as a basis for learning features or estimating the parameters of a graph model for a downstream prediction task. Examples include recent node embedding methods such as DeepWalk, node2vec, as well as graph-based deep learning algorithms. However, the simple random walk used by these methods is fundamentally tied to the identity of the node. This has three main disadvantages. First, these approaches are inherently transductive and do not generalize to unseen nodes and other graphs. Second, they are not space-efficient as a feature vector is learned for each node which is impractical for large graphs. Third, most of these approaches lack support for attributed graphs. To make these methods more generally applicable, we propose a framework for inductive network representation learning based on the notion of attributed random walk that is not tied to node identity and is instead based on learning a function $\Phi : \mathrm{\rm \bf x} \rightarrow w$ that maps a node attribute vector $\mathrm{\rm \bf x}$ to a type $w$. This framework serves as a basis for generalizing existing methods such as DeepWalk, node2vec, and many other previous methods that leverage traditional random walks.
Why Do People Resist Patient Portal Systems?: An Application of the Dual Factor Model of IT Usage

The implementation of patient portal systems (PPS) has potential benefits to both healthcare providers and their patients. However, evidence shows that PPS are being resisted by patients. Little research in IS has addressed this phenomenon. To understand PPS resistance, this study uses the dual factor model of IT usage to develop an integration of the user resistance model (URM) with the universal theory of acceptance and use of technology (UTAUT). Survey data were used to test the integrative model. A total of 265 responses were gathered from patients at a large international hospital. The data were analyzed using structural equation modeling (EQM). The results revealed resistance to change as an inhibitor to intentions to use the PPS. This study demonstrated the importance of integrating resistance to change with the technology use research, especially in healthcare settings. Moreover, this study is considered to be among the few studies in IS to incorporate patients’ perspectives regarding new healthcare technology.
A Randomized, Double-Blind, Placebo-Controlled Phase II Clinical Trial of Lovastatin for VariousEndpoints ofMelanoma Pathobiology

On the basis of large cardiovascular clinical trials of lipid-lowering agents that showed a considerable decrease in the incidence of primarymelanomas in the active agent arm, we have carried out a randomized, double-blind clinical trial examining the impact of lovastatin on various biomarkers of melanoma pathogenesis. Subjects with at least two clinically atypical nevi were randomized to receive oral lovastatin or placebo for a 6-month period. Clinical, histopathologic, and molecular biomarkers were evaluated for change in the two groups. Eighty subjects were randomized, evaluable, and included in the analyses. Lovastatin showed no benefit in comparisonwith placebo in the primary endpoint of decreasing the level of histopathologic atypia, nor in any of the secondary endpoints of decreasing clinical atypia, impact on nevus number, nor in showing significant changes in any of the molecular biomarkers. There were no significant differences in adverse event profiles for lovastatin compared with placebo. The lovastatin arm did show a significant and considerable decrease in total serum cholesterol and serum low-density lipoprotein (LDL) levels compared with placebo, an expected result. This finding bolsters confidence in subject compliance. Given the results of this trial, it is concluded that if lovastatin were to lower the incidence of melanoma, it would appear not to be doing so by reversing atypia of precursor atypical nevi over the 6-month time frame studied. Further research into the pathogenesis ofmelanoma and in other potential chemopreventive agents is needed. Cancer Prev Res; 7(5); 496–504. 2014 AACR.
Establishment and characterization of a cloned line of C3H mouse embryo cells sensitive to postconfluence inhibition of division.

A line of C3H mouse embryo cells highly sensitive to postconfluence inhibition of cell division, designated C3H/10T1/2, has been established, and a clone from this line (clone 8) has been characterized at early and late passages (200 to 450 days in culture). The cells of clone 8 are approximately 1730 cu µm in volume, their plating efficiency is 12 to 30%, their average generation time is 15.5 hr, and their saturation density is 2.9 to 3.8 × 104 cells/sq cm. The cell survival is 30% after freezing in 10% dimethyl sulfoxide and storage in liquid nitrogen. The cells of this clone are negative with respect to the spontaneous expression of C-type RNA murine viruses and viral antigens. Tests for mycoplasma contamination are negative. All the cells of this line are aneuploid with a stable mode of 81 chromosomes (40 to 60% of cells). Tests for tumorigenicity at all passages were negative. No spontaneous transformation in vitro has been observed in the stock cultures transferred on a regular schedule.
Security breach.

Florida State investigators terminated [name removed] for breach of confidentiality. The AIDS surveillance worker misused his position when he checked the county health department's computerized database of AIDS cases for dating purposes. A computer disk containing the database was anonymously sent to 2 newspapers and to State health officials in Pinellas County, FL in September 1996. The names of almost 4,000 HIV-positive persons appeared on the database. This particular case led to the position of stiffer penalties on breaches in security and the revamping of policies and procedures for handling AIDS lists.
Building a Web Effort Estimation Model Through Knowledge Elicitation

OBJECTIVE – The objective of this paper is to describe a case study where Bayesian Networks (BNs) were used to construct an expert-based Web effort model. METHOD – We built a single-company BN model solely elicited from expert knowledge, where the domain experts were two experienced Web project managers from a medium-size Web company in Auckland, New Zealand. This model was validated using data from eleven past finished Web projects. RESULTS – The BN model has to date been successfully used to estimate effort for numerous Web projects. CONCLUSIONS – Our results suggest that, at least for the Web Company that participated in this case study, the use of a model that allows the representation of uncertainty, inherent in effort estimation, can outperform expert-based estimates. Another nine companies have also benefited from using Bayesian Networks, with very promising results.
Contralaterally Controlled Functional Electrical Stimulation for Upper Extremity Hemiplegia

Background. Contralaterally controlled functional electrical stimulation (CCFES) is an experimental treatment intended to improve hand function after stroke. Objective. To compare the effects of 6 weeks of CCFES versus cyclic neuromuscular electrical stimulation (NMES) on upper extremity impairment and activity limitation in patients ≤6 months poststroke. Methods. Twenty-one participants were randomized to CCFES or cyclic NMES. Treatment for both groups consisted of daily stimulation-assisted repetitive hand-opening exercise at home plus twice-weekly lab sessions of functional task practice. Assessments were made at pretreatment and posttreatment and at 1 month and 3 months posttreatment. They included maximum voluntary finger extension angle, finger movement tracking error, upper extremity Fugl-Meyer score, Box and Blocks test, and Arm Motor Abilities test. Treatment effects were estimated using a 2-factor repeated measures analysis of variance with the value of the baseline measure as a covariate. Results. Seventeen patients completed the treatment phase (9 CCFES, 8 cyclic NMES). At all posttreatment time points, CCFES produced larger improvements than cyclic NMES on every outcome measure. Maximum voluntary finger extension showed the largest treatment effect, with a mean group difference across the posttreatment time points of 28° more finger extension for CCFES. Conclusions. The results favor CCFES over cyclic NMES though the small sample size limits the statistical power of the study. The effect size estimates from this study will be used to power a larger trial.
Measuring service quality on educational services of engineering curriculum using SERVQUAL model

This study is to investigate the perception and service expectation of engineering student to curriculum to measure quality of service. SERQUAL model developed by Parasuraman et al. is used to compare difference between expected and actually services perceived. The model proposes measuring service quality into five service dimensions. The survey was carried out from third and fourth year students in a case study of engineering faculty. The questionnaires of 1536 respondents from 19 curriculums are analyzed. It shows that the average score of perceived service quality in each dimension are as follow: Assurance 4.85, reliable 4.73, Tangible 4.53, empathy 4.72 and responsive 4.3 of full score of 7. The highest dimension is Assurance and the lowest dimension is Responsive. In all dimension by using t-test hypothesis, there are statistically significant difference between expectation and services perceived. Moreover, it is found that services perceived by students in all curriculums are statistically different. The work from this study would be the guideline for management to use to improve the level of education activity and service in engineering faculty.
