Globally convergent algorithms for dc operating point analysis of nonlinear circuits
No full textAn important objective in the analysis of an electronic circuit is to find its quiescent or DC operating point. This is the starting point for performing other types of circuit analysis. The most common method for finding the DC operating point of a nonlinear electronic circuit is the Newton-Raphson method (NR), a gradient search technique. There are known convergence issues with this method. NR is sensitive to starting conditions. Hence, it is not globally convergent and can diverge or oscillate between solutions. Furthermore, NR can only find one solution of a set of equations at a time. This paper discusses and evaluates a new approach to DC operating point analysis based on evolutionary computing. Evolutionary algorithms are globally convergent and can find multiple solutions to a problem by using a parallel search. At the operating point(s) of a circuit, the equations describing the current at each node are consistent and the overall error has a minimum value. Therefore, we can use an evolutionary algorithm to search the solution space to find these minima. We discuss the development of an analysis tool based on this approach. The principles of computer-aided circuit analysis are briefly discussed, together with the Newton-Raphson method and some of its variants. Various evolutionary algorithms are described. Several such algorithms have been implemented in a full circuit analysis tool. The performance and accuracy of the evolutionary algorithms are compared with each other and with NR. Evolutionary algorithms are shown to be robust and to have an accuracy comparable to that of NR. The performance is, at best, two-orders of magnitude worse than NR, although it should be noted that time-consuming setting of initial conditions is avoided
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters

Dwight Duncan and Richard Mohr: Who Should be Allowed to Marry: The Same Sex Debate
No full textA debate on issues surrounding same-sex marriage.
Dwight Duncan, a professor at the Southern New England School of Law, is one of the nation\u27s leading conservative authorities on legal ethics and constitutional law. He has written extensively about First Amendment rights, euthanasia and same-sex marriage, and has participated in many legal debates on gay and lesbian rights.
A practicing member of the Supreme Court of the United States Bar, Duncan is the principal co-author of the Supreme Court briefs on the prevailing side of Hurley v. Irish-American Gay, Lesbian and Bisexual Organization, in which the court ruled that forcing a veteran\u27s group to include a gay faction in its yearly St. Patrick\u27s Day parade violated the First Amendment.
Duncan holds degrees from Harvard University, Georgetown University Law School and the Roman Athenaeum of the Holy Cross in Rome, Italy.
Richard Mohr, author of A More Perfect Union: Why Straight America Must Stand Up for Gay Rights and one of America\u27s foremost gay thinkers, is a professor of philosophy at the University of Illinois. In 1988, he published Gays/Justice, a book documenting gay public policy issues, and his Gay Ideas: Outing and Other Controversies, raised national furor in the literary world when almost two dozen publishers refused to print it due to homoerotic representations.
Mohr lectures frequently on topics ranging from anti-gay violence, domestic partnership issues and the implementation of nondiscrimination policies for gays in the workplace
Incomprehension or resistance? : the Markan disciples and the narrative logic of Mark 4:1—8:30
No full textThe characterization of the Markan disciples has been and continues to be the object of much scholarly reflection and speculation. For many, the Markan author’s presentation of Jesus’ disciples holds a key, if not the key, to unlocking the purpose and function of the gospel as a whole. Commentators differ as to whether the Markan disciples ultimately serve a pedagogical or polemical function, yet they are generally agreed that the disciples in Mark come off rather badly, especially when compared to their literary counterparts in Matthew, Luke, and John.
This narrative-critical study considers the characterization of the Markan disciples within the Sea Crossing movement (Mark 4:1–8:30). While commentators have, on the whole, interpreted the disciples’ negative characterization in this movement in terms of lack of faith and/or incomprehension, neither of these, nor a combination of the two, fully accounts for the severity of language leveled against the disciples by the narrator (6:52) and Jesus (8:17–18). Taking as its starting point an argument by Jeffrey B. Gibson (1986) that the harshness of Jesus’ rebuke in Mark 8:14–21 is occasioned not by the disciples’ lack of faith or incomprehension but by their active resistance to his Gentile mission, this investigation uncovers additional examples of the disciples’ resistance to Gentile mission, offering a better account of their negative portrayal within the Sea Crossing movement and helping explain many of their other failures.
In short, this study argues that in Mark 4:1–8:26, the disciples are characterized as resistant to Jesus’ Gentile mission and to their participation in that mission, the chief consequence being that they are rendered incapable of recognizing Jesus’ vocational identity as Israel’s Messiah (Thesis A). This leads to a secondary thesis, namely, that in Mark 8:27–30, Peter’s recognition of Jesus’ messianic identity indicates that the disciples have finally come to accept Jesus’ Gentile mission and their participation in it (Thesis B).
“Chapter One: Introduction” offers a selective review of scholarly treatments of the Markan disciples, which shows that few scholars attribute resistance, let alone purposeful resistance, to the disciples.
“Chapter Two: The Rhetoric of Repetition” introduces the methodological tools, concepts, and perspectives employed in the study. It includes a section on narrative criticism, which focuses upon the story-as-discoursed and the implied author and reader, and a section on Construction Grammar, a branch of cognitive linguistics founded by Charles Fillmore and further developed by Paul Danove, which focuses upon semantic and narrative frames and case frame analysis.
“Chapter Three: The Sea Crossing Movement, Mark 4:1–8:30” addresses the question of Markan structure and argues that Mark 4:1–8:30 comprises a single, unified, narrative movement, whose action and plot is oriented to the Sea of Galilee and whose most distinctive feature is the network of sea crossings that transport Jesus and his disciples back and forth between Jewish and Gentile geopolitical spaces.
Following William Freedman, “Chapter Four: The Literary Motif” introduces two criteria (frequency and avoidability) for determining objectively what constitutes a literary motif and provides the methodological basis and starting point for the analyses performed in chapters five and six.
“Chapter Five: The Sea Crossing Motif” establishes and then carries out a lengthy narrative analysis of the Sea Crossing motif, which is oriented around Mark’s use of θάλασσα (thalassa) and πλοῖον (ploion), and “Chapter Six: The Loaves Motif” does the same for The Loaves motif, oriented around Mark’s use of ἄρτος (artos).
Finally, “Chapter Seven: The Narrative Logic of the Disciples (In)comprehension” draws together all narrative, linguistic, and exegetical insights of the previous chapters and offers a single coherent reading of the Sea Crossing movement that establishes Theses A and B.
Acute fluid shifts influence the assessment of serum vitamin D status in critically ill patients
No full textRecent reports have highlighted the prevalence of vitamin D deficiency and suggested an association with excess mortality in critically ill patients. Serum vitamin D concentrations in these studies were measured following resuscitation. It is unclear whether aggressive fluid resuscitation independently influences serum vitamin D.Nineteen patients undergoing cardiopulmonary bypass were studied. Serum 25(OH)D(3), 1α,25(OH)(2)D(3), parathyroid hormone, C-reactive protein (CRP), and ionised calcium were measured at five defined timepoints: T1 - baseline, T2 - 5 minutes after onset of cardiopulmonary bypass (CPB) (time of maximal fluid effect), T3 - on return to the intensive care unit, T4 - 24 hrs after surgery and T5 - 5 days after surgery. Linear mixed models were used to compare measures at T2-T5 with baseline measures.Acute fluid loading resulted in a 35% reduction in 25(OH)D(3) (59 ± 16 to 38 ± 14 nmol/L, P < 0.0001) and a 45% reduction in 1α,25(OH)(2)D(3) (99 ± 40 to 54 ± 22 pmol/L P < 0.0001) and i(Ca) (P < 0.01), with elevation in parathyroid hormone (P < 0.0001). Serum 25(OH)D(3) returned to baseline only at T5 while 1α,25(OH)(2)D(3) demonstrated an overshoot above baseline at T5 (P < 0.0001). There was a delayed rise in CRP at T4 and T5; this was not associated with a reduction in vitamin D levels at these time points.Hemodilution significantly lowers serum 25(OH)D(3) and 1α,25(OH)(2)D(3), which may take up to 24 hours to resolve. Moreover, delayed overshoot of 1α,25(OH)(2)D(3) needs consideration. We urge caution in interpreting serum vitamin D in critically ill patients in the context of major resuscitation, and would advocate repeating the measurement once the effects of the resuscitation have abated
Semiometrics: producing a compositional view of influence
No full textHigh-impact academic papers are not necessarily the most cited. For example, Einstein's 'Special Relativity' paper from 1905 received (and continues to receive) fewer citations from other papers than his 'Brownian Motion" paper of the same year, despite the former radically changing the course of an entire scientific discipline to a much greater extent. Similarly, 'impact' metrics using citation count alone are, it is argued, not adequate for determining the scientific influence of papers, authors or small groups of authors. Although valid, they remain controversial when used to determine influence of larger groups or journals. While the term 'impact' has become closely linked to a journal's citation-based Journal Impact Factor score, this thesis uses the term 'influence' to describe the wider effectiveness of research, combining citation and metadata analysis to allow richer calculations to be performed over large-scale document networks. As a result, more qualitative influence ratings can be determined and a broader outlook on scientific disciplines can be produced. These ratings are best applied using an ontology-based data source, allowing more efficient inference than under a traditional RDBMS system, and allowing easier integration between heterogeneous data sources. These metrics, termed 'Semantic Bibliometrics' or 'Semiometrics', can be applied at a variety of levels of granularity, allowing a compositional framework for impact and influence analysis. This thesis describes the process of data preparation, systems architecture, metric value and data integration for such a system, introducing novel approaches at all four stages, thereby creating a working semiometrics system for determining influence at different semantic levels of granularity
Cortical neuronal loss and hippocampal sclerosis are not detected by voxel-based morphometry in individual epilepsy surgery patients
No full textVoxel-based morphometry (VBM) has detected differences between brains of groups of patients
with epilepsy and controls, but the sensitivity for detecting subtle pathological changes in single subjects
has not been established. The aim of the study was to test the sensitivity of VBM using statistical parametric
mapping (SPM5) to detect hippocampal sclerosis (HS) and cortical neuronal loss in individual patients.
T1-weighted volumetric 1.5 T MR images from 13 patients with HS and laminar cortical neuronal loss
were segmented, normalised and smoothed using SPM5. Both modulated and non-modulated analyses
were performed. Comparisons of one control subject against the rest (n ¼ 23) were first performed to ascertain
the smoothing level with the lowest number of SPM changes in controls. Each patient was then compared
against the whole control group. The lowest number of SPM changes in control subjects was found
at a smoothing level of 10 mm full width half maximum for modulated and non-modulated data. In the
patient group, no SPM abnormalities were found in the affected temporal lobe or hippocampus at this
smoothing level. At lower smoothing levels there were numerous SPM findings in controls and patients.
VBM did not detect any abnormalities associated with either laminar cortical neuronal loss or HS. This
may be due to normalisation and smoothing of images and low statistical power in areas with larger interindividual
differences. This suggests that the methodology may currently not be suitable to detect particular
occult abnormalities possibly associated with seizure onset zone in individual epilepsy patients with
unremarkable standard structural MRI
Semiometrics: Applying Ontologies across Large-Scale Digital Libraries
No full textAs large-scale digital libraries become more available and complete, not to mention more numerous, it is clear there is a need for services that can draw together and perform inference calculations on the metadata produced. However, the traditional Relational Database Management System (RDBMS) model, while efficiently constructed and optimised for many business structures, does not necessarily cope well with issues of concurrent data updates and retrieval at the scale of hundreds of thousands of papers. At the same time the growth of RDF and the increasing interest in Semantic Web technologies perhaps begins to present a viable alternative at a scalable, practical level. This paper considers a specific application of large-scale metadata analysis and conducts scalability tests using real-world data. It concludes that RDF technologies are both a scalable and performance-realistic alternative to traditional RDBMS approaches. It also shows that for relationship-based queries on large-scale metadata stores, RDF technologies can significantly out-perform traditional RDBMS approaches by allowing both retrieval and updating of data in a timely manner
