Preference‐based session management for IP‐based mobile multimedia signaling
Authors: Kellerer Wolfgang , Wagner Matthias , Balke Wolf‐Tilo , Schulzrinne Henning 
Published: August 2004

AbstractThe increasing variety of mobile multimedia services raises the need for mechanisms to select those services whose capabilities best match individual user requirements. In this paper, we present an advanced concept for service personalization in next‐generation IP‐based mobile systems based on the notion of user preferences. The described concept features several enhancements for personalization, including the intuitive modeling of user preferences, the construction of complex preference terms from basic preference expressions and a stepwise refinement of profiles and preferences. We describe this solution applied to the signaling mechanism of the Session Initiation Protocol (SIP), which is the protocol suite for application control in current IP‐based mobile communication systems such as UMTS. In particular, our preference concept for personalized service management extends the conventional SIP preference modeling methods proposed so far: a preference order on the available service features is introduced that accounts for the specific demands of a user without a numerical ranking of features. We show how base preferences can be intuitively combined to complex preference expressions and explain how these relate to standard SIP feature preferences. Copyright © 2004 AEI
A hidden Markov modeling approach for admixture mapping based on case‐control data
Authors: Zhang Chun , Chen Kun , Seldin Michael F. , Li Hongzhe 
Published: August 2004

AbstractAdmixture mapping is potentially a powerful method for mapping genes for complex human diseases, when the disease frequency due to a particular disease‐susceptible gene is different between founding populations of different ethnicity. The method tests for association of the allele ancestry with the disease. Since the markers used to define ancestral populations are not fully informative for the ancestry status, direct test of such association is not possible. In this report, we develop a unified hidden Markov model (HMM) framework for estimating the unobserved ancestry haplotypes across a chromosomal region based on marker haplotype or genotype data. The HMM efficiently utilizes all the marker data to infer the latent ancestry states at the putative disease locus. In this HMM modelling framework, we develop a likelihood test for association of allele ancestry and the disease risk based on case‐control data. Existence of such association may imply linkage between the candidate locus and the disease locus. We evaluate by simulations how several factors affect the power of admixture mapping, including sample size, ethnicity relative risk, marker density, and the different admixture dynamics. Our simulation results indicate correct type 1 error rates of the proposed likelihood ratio tests and great impact of marker density on the power. The simulation results also indicate that the methods work well for the admixed populations derived from both hybrid‐isolation and continuous gene‐flowing models. Finally, we observed that the genotype‐based HMM performs very similarly in power as the haplotype‐based HMM when the haplotypes are known and the set of markers is highly informative. © 2004 Wiley‐Liss, Inc.
Chronic alterations in the cellular composition of spinal cord white matter following contusion injury
Authors: Rosenberg Lisa J. , Zai Laila J. , Wrathall Jean R. 
Published: August 2004

AbstractSpinal cord injury (SCI) involves the loss of neurons and glia due to initial mechanical and secondary biochemical mechanisms. Treatment with the sodium channel blocker tetrodotoxin (TTX) reduces acute white matter pathology and increases both axon density and hindlimb function chronically at 6 weeks after injury. We investigated the cellular composition of residual white matter chronically to determine whether TTX also has a significant effect on the numbers and types of cells present. Rats received an incomplete thoracic contusion injury, in the presence or absence of TTX (0.15 nmole) injected focally, beginning at 15 min prior to injury. Six weeks later, cell density was significantly increased in the residual white matter of the dorsal, lateral, and ventral funiculi, both rostral and caudal to the injury site in both TTX‐treated and injury control groups. Oligodendrocyte and astrocyte density was similar to normal but large numbers of cells expressing microglia/macrophage markers were present. Labeling with the progenitor markers nestin and NG2 showed that precursor cell density had also doubled or tripled as compared with uninjured controls. Some of these cells were also labeled for antigens that indicate their possible progression along an oligodendrocyte or astrocyte lineage. Our results support the hypothesis that the beneficial effect of TTX in SCI is related to its preservation of axons per se; no effect on chronic white matter cell composition was detected. They highlight the profound changes in cellular composition in preserved white matter chronically at 6 weeks after injury, including the accumulation of endogenous progenitor cells and the persistence of activated macrophages/microglia. The manipulation of these endogenous cells may be used in the future to enhance recovery after SCI. © 2004 Wiley‐Liss, Inc.
Startup characteristics of a vertically placed high‐temperature heat pipe fin
Authors: Zhao Wei‐lin , Zhuang Jun , Zhang Hong 
Published: August 2004

AbstractIn order to observe startup characteristics, a vertically installed high‐temperature heat pipe fin was tested. The temperature curves during the startup process are given. It was found that the evaporator bottom temperature in the high‐temperature heat pipe fin with a constant heat input increased very quickly over time. The temperature at the evaporator top and the condenser temperature lagged behind the temperature of the evaporator bottom. The evaporator outlet temperature coincided with the condenser middle temperature. The temperature at the end of the condenser exhibited a phenomenon of temperature pulsation. If the high‐temperature heat pipe fin was placed horizontally for a certain period of time and then tested in its vertical position, the temperature pulsation phenomenon at the condenser disappeared and a good isothermal condition emerged. Further analysis showed that larger heat inputs yielded faster startups and weaker pulsation during the startup period. © 2004 Wiley Periodicals, Inc.

Thermal analysis of flip chip plastic ball grid array assembly
Authors: Su Ay , Liu Yi‐Wei 
Published: August 2004

AbstractSteady‐state thermal performance of the 164‐Lead flip chip plastic ball grid array (FC‐PBGA) under low to moderate convective air cooling conditions is simulated with CFX software. A package with three different substrates is investigated. Package performance is presented in the form of a linear relationship between the normalized junction to ambient thermal parameter (θJA) versus the normalized board to ambient thermal parameter (θJB). The chip corner and the contact surface have a larger temperature difference, produce a mismatch phenomenon, and result in the destruction of the solder ball. © 2004 Wiley Periodicals, Inc.

Published: August 2004

AbstractThe Syndrom Kurztest SKT is a brief neuropsychological test battery that consists of nine subtests and defines two independent factors of memory and attention deficit. The aim of this study was to validate the Korean version of the SKT. The reliability of each subtest among three parallel Forms (A, B and C) of the Korean version was high (r = 0.46–0.95). The SKT had good concurrent validity with the Mini‐Mental State Examination (r = −0.83, p < 0.001). Factor analysis confirmed the presence of two primary factors, memory and attention. The overall similarities of the factor structures for the Korean data and those for the data from Germany and the USA provide evidence of the transcultural stability of the SKT.

Bayesian updating of flood inundation likelihoods conditioned on flood extent data
Authors: Bates Paul D. , Horritt Matthew S. , Aronica Giuseppe , Beven Keith 
Published: August 2004

AbstractPreviously we have detailed an application of the generalized likelihood uncertainty estimation (GLUE) procedure to estimate spatially distributed uncertainty in models conditioned against binary pattern data contained in flood inundation maps. This method was applied to two sites where a single consistent synoptic image of inundation extent was available to test the simulation performance of the method. In this paper, we extend this to examine the predictive performance of the method for a reach of the River Severn, west‐central England. Uniquely for this reach, consistent inundation images of two major floods have been acquired from spaceborne synthetic aperture radars, as well as a high‐resolution digital elevation model derived using laser altimetry. These data thus allow rigorous split sample testing of the previous GLUE application. To achieve this, Monte Carlo analyses of parameter uncertainty within the GLUE framework are conducted for a typical hydraulic model applied to each flood event. The best 10% of parameter sets identified in each analysis are then used to map uncertainty in flood extent predictions using the method previously proposed for both an independent validation data set and a design flood. Finally, methods for combining the likelihood information derived from each Monte Carlo ensemble are examined to determine whether this has the potential to reduce uncertainty in spatially distributed measures of flood risk for a design flood. The results show that for this reach and these events, the method previously established is able to produce sharply defined flood risk maps that compare well with observed inundation extent. More generally, we show that even single, poor‐quality inundation extent images are useful in constraining hydraulic model calibrations and that values of effective friction parameters are broadly stationary between the two events simulated, most probably reflecting their similar hydraulics.

Coping with SOX 404 requirements
Authors: Moeller Robert 
Published: August 2004

AbstractAt first, no one paid much attention to Section 404 of the Sarbanes‐Oxley Act (SOX).To many, it seemed to affect only public accounting firms. But Section 404 requires management to certify the effectiveness of the internal controls that are the basis of financial reporting. And if the certification is wrong, corporate officers can face personal criminal penalties! So how do you cope with the challenges and complexities generated by Section 404? © 2004 Wiley Periodicals, Inc.

Integrating target costing and the balanced scorecard
Authors: Souissi Mohsen , Ito Kazunoti 
Published: August 2004

AbstractTarget costing (TC) has been used successfully for years by leading Japanese companies, principally to motivate design engineers to look for innovative ways to manage cost while not neglecting other crucial dimensions such as product quality and time‐to‐market. This article explores ways that the balanced scorecard (BSC) may help in the target costing process—specifically, how the balanced scorecard could serve as an interactive control system of intensive review, dialogues, and debates to ensure that a company is heading toward its targets. © 2004 Wiley Periodicals, Inc.
Existence of T*(3, 4,v)‐codes
Authors: Wang J. , Ji L. 
Published: August 2004

AbstractA word of length k over an alphabet Q of size v is a vector of length k with coordinates taken from Q. Let Q*4 be the set of all words of length 4 over Q. A T*(3, 4, v)‐code over Q is a subset C*⊆ Q*4 such that every word of length 3 over Q occurs as a subword in exactly one word of C*. Levenshtein has proved that a T*(3, 4, vv)‐code exists for all even v. In this paper, the notion of a generalized candelabra t‐system is introduced and used to show that a T*(3, 4, v)‐code exists for all odd v. Combining this with Levenshtein's result, the existence problem for a T*(3,4, v)‐code is solved completely. © 2004 Wiley Periodicals, Inc. J Combin Designs 13: 42–53, 2005.
General practice, primary care, and health service psychology: Concepts, competencies, and the Combined‐Integrated model
Authors: Schulte Timothy J. , Isley Elayne , Link Nancy , Shealy Craig N. , Winfrey LaPearl Logan 
Published: August 2004

AbstractThe profession of psychology is being impacted profoundly by broader changes within the national system of health care, as mental and behavioral health services are being recognized as essential components of a comprehensive, preventive, and cost‐efficient primary care system. To fully define and embrace this role, the discipline of professional psychology must develop a shared disciplinary identity of health service psychology and a generalized competency‐based model for doctoral education and training. This very framework has been adopted by Combined‐Integrated (C‐I) doctoral programs in professional psychology, which train across the practice areas (clinical, counseling, and school psychology) to provide a general and integrative foundation for their students. Because C‐I programs produce general practitioners who are competent to function within a variety of health service settings, this innovative training approach has great potential to educate and train psychologists for a changing health care marketplace. © 2004 Wiley Periodicals, Inc.

Unified professional psychology: Implications for the Combined‐Integrated model of doctoral training
Authors: Henriques Gregg R. , Sternberg Robert J. 
Published: August 2004

AbstractThe authors outline a new identity for the professional psychologist termed Unified Professional Psychology (UPP). UPP combines recent movements toward a unified psychological science, an independent professional psychology, and Combined‐Integrated (C‐I) doctoral training programs in psychology. The value in the synthesis of these ideas is that they (a) provide a comprehensive system of thought that defines the science and practice of psychology in a commensurable manner, (b) offer a clear identity for the professional psychologist, and (c) set the stage for a training model that develops competencies that will prepare graduates to serve as leaders and advocates in a wide array of health settings. Issues pertaining to why a new view is needed and how UPP specifies the science–practice relationship are addressed in detail. © 2004 Wiley Periodicals, Inc. J Clin Psychol.
A model and method for “making” a Combined‐Integrated psychologist: Equilintegration (EI) Theory and the Beliefs, Events, and Values Inventory (BEVI)
Authors: Shealy Craig N. 
Published: August 2004

AbstractAlthough the Consensus Conference on Combined and Integrated Doctoral Training in Psychology (e.g., Bailey, 2003) generated much content of relevance to the structure and commitments of Combined‐Integrated (C‐I) programs, faculty, and students—and Competencies 2002: Future Directions in Education and Credentialing in Professional Psychology (www.appic.org) developed language and guidelines regarding the knowledge areas, skills, and values that students in professional psychology programs should acquire and demonstrate—specific models and methods are necessary to translate these professional guidelines and aspirations into reality. This article offers one such model, Equilintegration (EI) Theory, and method, the Beliefs, Events, and Values Inventory (BEVI), that can be used by faculty, training staff, supervisors, and students in C‐I programs to operationalize, assess, and cultivate basic values of education and training from a C‐I perspective (e.g., self‐awareness, self‐assessment, and self‐reflection). In addition to this model and method, relevant background information, theory, and research are presented along with attendant implications, hypotheses, and principles. © 2004 Wiley Periodicals, Inc.

Kiwi fruit (Actinidia chinensis L.) polysaccharides exert stimulating effects on cell proliferation via enhanced growth factor receptors, energy production, and collagen synthesis of human keratinocytes, fibroblasts, and skin equivalents
Authors: Deters Alexandra M. , Schröder Klaus R. , Hensel Andreas 
Published: August 2004

AbstractWithin physiological engineering exogenous carbohydrates were recently confirmed as pharmacologically active compounds. To investigate potential dermatological activity purified polysaccharides from kiwi fruits (Actinidia chinensis L., Actinidiaceae) were characterized concerning monomer composition, linkage types and molecular weights and were tested under in vitro conditions for regulating activities on cell physiology of human keratinocytes, fibroblasts, and skin equivalents. Ten micrograms per milliliter of raw polysaccharide, neutral type‐II‐arabinogalactans, and acidic arabinorhamnogalacturonans of kiwi fruits stimulated cell proliferation of human keratinocytes (NHK, HaCaT) up to 30% significantly while mitochondrial activity was stimulated for nearly 25% in regard to control cells. Fibroblasts were not as sensitive as keratinocytes but >130 μg/ml kiwi fruit polysaccharides increased proliferation and ATP‐synthesis significantly, too. Proliferation‐stimulating activity was dependent on terminal 1‐α‐l‐arabinose residues since enzymatic release of these sugar moieties caused significantly decreased proliferation of HaCaT and fibroblasts of about 10% in regard to untreated cells. In three dimensional skin equivalents, it was shown that the polysaccharides led to a doubled collagen synthesis of fibroblasts compared to the normally strongly reduced biosynthetic activity. © 2004 Wiley‐Liss, Inc.
Packing triangles in a graph and its complement
Authors: Keevash Peter , Sudakov Benny 
Published: August 2004

AbstractHow few edge‐disjoint triangles can there be in a graph G on n vertices and in its complement $\overline {G}$? This question was posed by P. Erdős, who noticed that if G is a disjoint union of two complete graphs of order n/2 then this number is n2/12 + o(n2). Erdős conjectured that any other graph with n vertices together with its complement should also contain at least that many edge‐disjoint triangles. In this paper, we show how to use a fractional relaxation of the above problem to prove that for every graph G of order n, the total number of edge‐disjoint triangles contained in G and $\overline {G}$ is at least n2/13 for all sufficiently large n. This bound improves some earlier results. We discuss a few related questions as well. © 2004 Wiley Periodicals, Inc. J Graph Theory 47: 203–216, 2004
Improved bounds for the chromatic number of a graph
Authors: Hakimi S. Louis , Schmeichel Edward 
Published: August 2004

AbstractAfter giving a new proof of a well‐known theorem of Dirac on critical graphs, we discuss the elegant upper bounds of Matula and Szekeres‐Wilf which follow from it. In order to improve these bounds, we consider the following fundamental coloring problem: given an edge‐cut (V1, V2) in a graph G, together with colorings of 〈V1〉 and 〈V2〉, what is the least number of colors in a coloring of G which “respects” the colorings of 〈V1〉 and 〈V2〉 ? We give a constructive optimal solution of this problem, and use it to derive a new upper bound for the chromatic number of a graph. As easy corollaries, we obtain several interesting bounds which also appear to be new, as well as classical bounds of Dirac and Ore, and the above mentioned bounds of Matula and Szekeres‐Wilf. We conclude by considering two algorithms suggested by our results. © 2004 Wiley Periodicals, Inc. J Graph Theory 47: 217–225, 2004
A constructive approach for the lower bounds on the Ramsey numbers R (s, t)
Authors: Xiaodong Xu , Zheng Xie , Radziszowski Stanisław P. 
Published: August 2004

AbstractGraph G is a (k, p)‐graph if G does not contain a complete graph on k vertices Kk, nor an independent set of order p. Given a (k, p)‐graph G and a (k, q)‐graph H, such that G and H contain an induced subgraph isomorphic to some Kk−1‐free graph M, we construct a (k, p + q − 1)‐graph on n(G) + n(H) + n(M) vertices. This implies that R (k, p + q − 1) ≥ R (k, p) + R (k, q) + n(M) − 1, where R (s, t) is the classical two‐color Ramsey number. By applying this construction, and some its generalizations, we improve on 22 lower bounds for R (s, t), for various specific values of s and t. In particular, we obtain the following new lower bounds: R (4, 15) ≥ 153, R (6, 7) ≥ 111, R (6, 11) ≥ 253, R (7, 12) ≥ 416, and R (8, 13) ≥ 635. Most of the results did not require any use of computer algorithms. © 2004 Wiley Periodicals, Inc. J Graph Theory 47: 231–239, 2004
