Does the Nature of Chief Complaint, Gender, or Age Affect Time to Be Seen in the Emergency Room  [PDF]
Ayesha Sattar, Kenneth Sable, Antonios Likourezos, Christian Fromm, John Marshall
Open Journal of Emergency Medicine (OJEM) , 2014, DOI: 10.4236/ojem.2014.22006

Objectives: EM physicians may be biased in seeing patients presenting with nonspecific complaints or requiring more extensive work-ups. The goal of our study was to ascertain if chief complaint affected time to be seen (TTBS) in the ED. Methods: A retrospective report was generated from the EMR for all moderate acuity patients who visited the ED from January 2005 to December 2010 at a large urban teaching hospital. Abdominal pain, alcohol intoxication, back pain, chest pain, cough, dyspnea, dizziness, fall, fever, flank pain, headache, infection, pain (nonspecific), psychiatric evaluation, “sent by MD”, vaginal bleeding, vomiting, and weakness were the most common complaints. Non-Parametric Independent Sample Tests assessed median TTBS between complaints, gender, and age. Chisquare testing assessed for differences in the distribution of arrival times. Results: We obtained data from 116,194 patients. Patients presenting with weakness and dizziness waited the longest time of 35 minutes and patients with flank pain waited the shortest with 24 minutes. Males waited 30 minutes and females waited 32 minutes. Younger females between the ages of 18 - 50 waited significantly longer when presenting with a chief complaint of abdominal pain, chest pain, or flank pain. There was no difference in the distribution of arrival times for these complaints. Conclusion: There is a significant bias toward seeing young male patients more quickly than women or older males. Patients might benefit from efforts to educate EM physicians on the delays and potential quality issues associated with this bias in an attempt to move toward more egalitarian patient selection.

Ethyl 5-methoxy-2-trifluoromethyl-1H-indole-3-carboxylate
Aurelien Crochet,Isak Alimi,Christian G. Bochet,Katharina M. Fromm
Acta Crystallographica Section E , 2013, DOI: 10.1107/s1600536813002614
Abstract: The title compound, C13H12F3NO3, is almost planar if one excludes the F atoms of the –CF3 group [maximum deviation for the other hetero atoms = 0.069 (1) ], and the dihedral angle between the pyrrole and benzene ring of the indole system is 2.54 (8)°. In the crystal, molecules are linked by N—H...O hydrogen bonds, forming chains propagating along the a-axis direction. These chains are linked via C—H...O and C—H...F hydrogen bonds, forming a three-dimensional network.

Types and Forms of Emergence
Jochen Fromm
Physics , 2005,
Abstract: The knowledge of the different types of emergence is essential if we want to understand and master complex systems in science and engineering, respectively. This paper specifies a universal taxonomy and comprehensive classification of the major types and forms of emergence in Multi-Agent Systems, from simple types of intentional and predictable emergence in machines to more complex forms of weak, multiple and strong emergence.
On Engineering and Emergence
Jochen Fromm
Physics , 2006,
Abstract: The engineering and design of self-organizing systems with emergent properties is a long-standing problem in the field of complex and distributed systems, for example in the engineering of self-organizing Multi-Agent Systems. The problem of combining engineering with emergence - to find a simple rule for a complex pattern - equals the problem of science in general. Therefore the answers are similar, and the scientific method is the general solution to the problem of engineering complex systems.
Ten Questions about Emergence
Jochen Fromm
Physics , 2005,
Abstract: Self-Organization is of growing importance for large distributed computing systems. In these systems, a central control and manual management is exceedingly difficult or even impossible. Emergence is widely recognized as the core principle behind self-organization. Therefore the idea to use both principles to control and organize large-scale distributed systems is very attractive and not so far off. Yet there are many open questions about emergence and self-organization, ranging from a clear definition and scientific understanding to the possible applications in engineering and technology, including the limitations of both concepts. Self-organizing systems with emergent properties are highly desirable, but also very challenging. We pose ten central questions about emergence, give preliminary answers, and identify four basic limits of self-organization: a size limit, a place limit, a complexity limit and finally a combinatorial limit.
Gromov Compactness in Hoelder Spaces and Minimal Connections on Jet Bundles
Viktor Fromm
Mathematics , 2008,
Abstract: The goal of this work is to establish a proof of the Gromov convergence in Hoelder spaces for curves with a totally real boundary condition following the original geometric idea of Gromov. We use a local reflection principle in neighbourhoods of the totally real submanifold as developed by Ivashkovich and Shevchishin and existence results for special connections on spaces of jet bundles to obtain higher regularity and Gromov-Schwarz estimates along the boundary.
Morse Homotopy and Homological Conformal Field Theory
Viktor Fromm
Mathematics , 2013,
Abstract: By studying spaces of flow graphs in a closed oriented manifold, we construct operations on its cohomology, parametrized by the homology of the moduli spaces of compact Riemann surfaces with boundary marked points. We show that the operations satisfy the gluing axiom of an open homological conformal field theory. This complements previous constructions due to R. Cohen et al., K. Costello and M. Kontsevich and is also the Morse theoretic counterpart to a conjectural construction of operations on the Lagrangian Floer homology of the zero section of a cotangent bundle, obtained by studying uncompactified moduli spaces of higher genus pseudoholomorphic curves.
A sensitive study of the peculiar jet structure HST-1 in M87
Carolina Casadio,José L. Gómez,Marcello Giroletti,Gabriele Giovannini,Kazuhiro Hada,Christian Fromm,Manel Perucho,José-María Martí
Physics , 2013, DOI: 10.1051/epjconf/20136106004
Abstract: To obtain a better understanding of the location and mechanisms for the production of the gamma-ray emission in jets of AGN we present a detailed study of the HST-1 structure, 0.8 arcsec downstream the jet of M87, previously identified as a possible candidate for TeV emission. HST-1 shows a very peculiar structure with superluminal as well as possible stationary sub-components, and appears to be located in the transition from a parabolic to a conical jet shape, presumably leading to the formation of a recollimation shock. This scenario is supported by our new RHD simulations in which the interaction of a moving component with a recollimation shock leads to the appearance of a new superluminal component. To discern whether HST-1 is produced by a recollimation shock or some other MHD instability, we present new polarimetric 2.2 and 5 GHz VLBA, as well as 15, 22 and 43 GHz JVLA observations obtained between November 2012 and March 2013.
