1. Strongly Typed Genetic Programming in Evolving Cooperation Strategies - Thomas Haynes; Roger Wainwright; Sandip Sen; Ip Sen; Dale Schoenefeld
A key concern in genetic programming (GP) is the size of the state--space which must be searched for large and complex problem domains. One method to reduce the state--space size is by using Strongly Typed Genetic Programming (STGP). We applied both GP and STGP to construct cooperation strategies to be used by multiple predator agents to pursue and capture a prey agent on a grid--world. This domain has been extensively studied in Distributed Artificial Intelligence (DAI) as an easy--to--describe but difficult--to--solve cooperation problem. The evolved programs from our systems are competitive with manually derived greedy algorithms. In particular the STGP...

3. An Ecient Constraint Handling Method for Genetic Algorithms - Kalyanmoy Deb
Many real-world search and optimization problems involve inequality and/or equality constraints and are thus posed as constrained optimization problems. In trying to solve constrained optimization problems using genetic algorithms (GAs) or classical optimization methods, penalty function methods have been the most popular approach, because of their simplicity and ease of implementation. However, since the penalty function approach is generic and applicable to any type of constraint (linear or nonlinear), their perfor-mance is not always satisfactory. Thus, researchers have developed sophisticated penalty functions specific to the problem at hand and the search algorithm used for optimization. However, the most dicult aspect...

4. ORIGINAL PAPER Assortative mating for Cigarette Smoking and for Alcohol Consumption in Female Australian Twins and their Spouses - Nicholas G. Martin; Æ Pamela; A. F. Madden
Background Non-random mating affects population var-iation for substance use and dependence. Developmentally, mate selection leading to positive spousal correlations for genetic similarity may result in increased risk for substance use and misuse in offspring. Mate selection varies by co-hort and thus, assortative mating in one generation may produce marked changes in rates of substance use in the next. We aim to clarify the mechanisms contributing to spousal similarity for cigarette smoking and alcohol con-sumption. Methods Using data from female twins and their male spouses, we fit univariate and bivariate twin models to examine the contribution of primary assortative mating and...

7. Management of Sickle Cell Disease Summary of the 2014 Evidence-Based Report by Expert Panel Members
IMPORTANCE Sickle cell disease (SCD) is a life-threatening genetic disorder affecting nearly 100 000 individuals in the United States and is associated with many acute and chronic complications requiring immediate medical attention. Two disease-modifying therapies, hydroxyurea and long-term blood transfusions, are available but underused. OBJECTIVE To support and expand the number of health professionals able and willing to provide care for persons with SCD. EVIDENCE REVIEW Databases of MEDLINE (including in-process and other nonindexed citations), EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, CINAHL, TOXLINE, and Scopus were searched using prespecified search terms and keywords to...

Abstract Phenomena of hybridization can affect the ecology and evolution of the species involved in the process, as well as their communities. Although numerous papers focus upon the problem of taxonomy, few of these have attempted to study hybrid zones in relation to the analysis of their communities. On the Iberian Peninsula, hybridization phenomena among different oak species are frequent. It is, however, between Quercus faginea Lam. and Quercus pubes-cens Willd. where the most noteworthy hybridization phenomenon occurs. In this respect, we are familiar with the existence of different introgression levels but we are unaware of whether these hybrids are...

11. Research Article Multiobjective-Optimized Design of a New UWB Antenna for UWB Applications - A. Rubio Bretones; R. Gómez-martín; K. Palmer
Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. A multiobjective genetic algorithm has been applied to design a new printed, bow-tie antenna for ultrawideband applications, that is, ground penetrating radar, short range and high data rate communications, and so forth. The ultrawideband performance with respect to antenna impedance and gain is achieved by an optimized resistive loading profile and flare angle. A low-cost prototype is manufactured and numerical simulations are validated with measurements. 1.

13. BY - Human Phenotypes; Hearing Loss; Jorune Balciuniene; Acta Universitatis Upsaliensis
This thesis focuses on the identification of genetic factors underlying two inherited human phenotypes: hearing loss and monoamine oxidase activity. Non-syndromic hearing loss segregating in a Swedish family was tested for linkage to 13 previously reported candidate loci for hearing disabilities. Linkage was found to two loci: DFNA12 (11q22-q24) and DFNA2 (1p32). A detailed analysis of the phenotypes and haplotypes shared by the affected individuals supported the hypothesis of digenic inheritance of hearing disability in the Swedish family. Mutation screening of α-tectorin, a gene residing within the DFNA12 region revealed a mutation of a conserved amino acid (Cys to Ser),...

The number of alleles, product size and heterozygosity at each of the eight microsatellite loci are shown in Table 1. All of the examined loci showed a distinct allelic variation ranging from 2-8 alleles in the bears examined. Alleles at each locus differed by multiples of two in size. All the polymorphic loci conformed to Hardy-Weinberg expectations except for hGUT-3, which may have null alleles (Table 1). The eight loci showed relatively low allelic variations and low heterozygosities. This may be caused by a small sampling area for this species or by the population being isolated. To elucidate the cause,...

16. Forest Structure and Fungal Endophytes - Kari Saikkonen
Interactions among endophytic fungi, woody plants and herbivores are usually studied emphasizing fungal mediated plant-herbivore interactions. Seeking evidence for indication of causal relationships between fungi and herbivores sharing the host plant has been self-feeding reasoning in endophyte literature since the findings that some endophytes, particularly seed-borne grass-endophytes in agronomic arena, negatively affect herbivores. Although many studies with natural grass systems, and especially with horizontally by spores transmitted tree-endophytes, have shown more variable effects, alternative approaches have seldom been brought up for discussion. Here, I suggest that the mutualistic nature of plant fungus interactions via enhanced herbivore resistance should be reconsidered...

17. Results of a haplotype-based GWAS for recurrent laryngeal neuropathy in the horse - Marie-capucine Dupuis; Zhiyan Zhang; Tom Druet; Jean-marie Denoix; Carole Charlier; Pierre Lekeux; Michel Georges
Abstract Recurrent laryngeal neuropathy (RLN) is a major upper-airway disease of horses that causes abnormal respiratory noise during exercise and can impair perfor-mance. Etiopathogenesis remains unclear but genetic fac-tors have been suspected for many decades. The objective of this study was to identify risk loci associated with RLN. To that end we genotyped 234 cases (196 Warmbloods, 20

18. The Convergence Analysis of Parallel Genetic Algorithm Based on Allied Strategy - Feng Linab; Wei Sunb; Kc Changb
Genetic algorithms (GAs) have been applied to many difficult optimization problems such as track assignment and hypothesis managements for multisensor integration and data fusion. However, premature convergence has been a main problem for GAs. In order to prevent premature convergence, we introduce an allied strategy based on biological evolution and present a parallel Genetic Algorithm with the allied strategy (PGAAS). The PGAAS can prevent premature convergence, increase the optimization speed, and has been successfully applied in a few applications. In this paper, we first present a Markov chain model in the PGAAS. Based on this model, we analyze the convergence...
