A New Dantzig-Wolfe Reformulation And Branch-And-Price Algorithm For The Capacitated Lot Sizing Problem With Set Up Times
Full text linkThe textbook Dantzig-Wolfe decomposition for the Capacitated LotSizing Problem (CLSP),as already proposed by Manne in 1958, has animportant structural deficiency. Imposingintegrality constraints onthe variables in the full blown master will not necessarily givetheoptimal IP solution as only production plans which satisfy theWagner-Whitin condition canbe selected. It is well known that theoptimal solution to a capacitated lot sizing problem willnotnecessarily have this Wagner-Whitin property. The columns of thetraditionaldecomposition model include both the integer set up andcontinuous production quantitydecisions. Choosing a specific set upschedule implies also taking the associated Wagner-Whitin productionquantities. We propose the correct Dantzig-Wolfedecompositionreformulation separating the set up and productiondecisions. This formulation gives the samelower bound as Manne'sreformulation and allows for branch-and-price. We use theCapacitatedLot Sizing Problem with Set Up Times to illustrate our approach.Computationalexperiments are presented on data sets available from theliterature. Column generation isspeeded up by a combination of simplexand subgradient optimization for finding the dualprices. The resultsshow that branch-and-price is computationally tractable andcompetitivewith other approaches. Finally, we briefly discuss how thisnew Dantzig-Wolfe reformulationcan be generalized to other mixedinteger programming problems, whereas in theliterature,branch-and-price algorithms are almost exclusivelydeveloped for pure integer programmingproblems.branch-and-price;Lagrange relaxation;Dantzig-Wolfe decomposition;lot sizing;mixed-integer programming
Father Andrew Mullen 1790-1818: a study in early nineteenth century spirituality
Full text linkThis thesis is laid out in three parts: Part I. The life and death of Andrew Mullen. The life is based, to a large extent, on a long letter to his mother, Catherine Mullen, dated 7 January 1810. The letter gives a definite insight into his spirituality based on his membership of the Archconfraternity of the Blessed Sacrament. There is a hint that he had a premonition of an early death. Part II. The burial of Andrew Mullen and the immediate cult to him This is based on documentary evidence. Part III. Most of this part is a catalogue of testimonies taken from 1993 onwards. Then there is the conclusion on the popular devotion to Andrew Mullen stressing the theological aspect of the subject. In the course of writing the thesis it was decided to separate the documentary evidence from the oral tradition. This was advantageous in developing the thesis, and the documents provided a secure basis for the oral tradition. Two pieces of information were found in March 1997. They are death notices: 2 January 1819, The Leinster Journal and 7 January 1819, The Car low Morning Post. There is a slight discrepancy between the two on the date of his death. Also this discrepancy shows a slight difference from the date of the tombstone
Biblical motives in Dr. Martin Luther King´s speeches.
No full textThis paper is concerned with the last speech of Martin Luther King Jr., known as {\clqq}I have Been To The Mountain Top``, and with the way of how its author uses biblical motives in it. The first part of this paper offers a short overview of Martin Luther King{\crq}s life and activities in the struggle against rasist separation of the black Amarican population. The second part contains the text of the speech with the biblical motives and quotations highlighted. Then the author describes the context of eqch of these bilical quotations in the Bible itself end then in the Martin Luther King{\crq}s speech. There is one attachment containing the Czech translation of the discussed speech by the author of the paper
Interview with Father James Martin
Full text linkIn May 2011, the Ignatian Faculty Scholars at Regis University conducted a Skype interview with Father James Martin, S. J., author of The Jesuit Guide to Almost Everything. The Scholars had used Father Martin’s book as a text for their year of study, which focused on Ignatian Spirituality, the Ignatian Pedagogical Paradigm, and teaching and learning at a Jesuit university. The interview was transcribed and is printed below. Father Martin reflects on the book, and responds to questions about the book itself, about finding God in all learners, and about the Church

Distribution. Qld, NSW. Hosts. CUNONIACEAE: Ceratopetalum apetalum. ELAEOCARPACEAE: Sloanea woollsii (ASCU, ANIC). EPACRIDACEAE: Trochocarpa laurina (ASCU, ANIC). LAURACEAE: Neolitsea sp. (Martin 1999). ATHEROSPERMATACEAE: Doryphora sassafras (Martin, 1999, ASCU, ANIC). MYRTACEAE: Austromyrtus sp. (Martin 1999); Waterhousea floribunda (ASCU, ANIC). PROTEACEAE: Orites excelsa (ASCU, ANIC). Comments. This species is widespread in tropical, subtropical and temperate rainforests and is now known to occur in both dark and light forms. It is likely that this species will be found in suitable rainforest habitats south to Victoria. The type series collected from far north Queensland is the only sample seen by the author showing sexual dimorphism. Populations sampled by the author from subtropical and temperate areas do not show dimorphism. As pointed out by Martin (1999), the yellow wax of this species is distinctive. This species may be superficially confused with A. coombsi sp. n., a species also with yellow wax, but can be separated by the characters in the key.Published as part of Gillespie, Peter S., 2012, A review of the whitefly genus Aleurocanthus Quaintance & Baker (Hemiptera: Aleyrodidae) in Australia, pp. 1-42 in Zootaxa 3252 on pages 12-13, DOI: 10.5281/zenodo.24642
Heritability and Linkage Analysis of Appendicitis Utilizing Age at Onset
Get PDFAppendicitis usually afflicts the young, but there is a large tail in the distribution of onset age. The genetics of this disease are still not well understood. A heritability analysis and genome wide linkage analysis of a large twin dataset was undertaken. Treating age of onset of appendicitis as a censored survival trait revealed a heritability of 0.21, and found evidence of linkage to Chromosome 1p37.3.

International Symposium on Evolutionary Breeding in Cereals
No full textEvolutionary plant breeding has a long history, but has so far not become part of mainstream breeding research, nor has it been implemented in practice to any substantial degree.
However, over the last decade, research in evolutionary plant breeding has markedly intensified. For example, there are currently major research projects on-going in this area, including the EU funded project SOLIBAM, the Wheat Breeding LINK project in the UK, and the Danish Biobreed project. Also, a new 3-year international research project called COBRA on this topic is due to start in March 2013. Funded by the CORE Organic 2 Eranet the project brings together over 40 partner organizations from 18 European countries.
In addition, interest in evolutionary plant breeding is growing among farmers, breeders and policy makers. In fact, there are currently encouraging developments in the imminent revision of seed legislation in Europe that could lead to more room for evolutionary plant breeding approaches in the future.
This renewed interest in evolutionary plant breeding is partly due to the recognition that mainstream plant breeding is limited in terms of its engagement with end users, i.e. farmers and growers. More urgently however, effects of climate change on agricultural production have become more noticeable and there is also a growing awareness of increasing resource constraints; together, these will create more stressful growing conditions for agricultural crops. With this background, it is now being recognized that crops need to be able to cope with more variable, contrasting, fluctuating, and generally more unpredictable growing conditions.
To be able to deal with this large and increasing environmental variability, plant breeding needs to become more decentralized and diversified. Evolutionary plant breeding offers great potential in this respect. The contributions collated from this symposium explore this potential as well as the limitations of evolutionary plant breeding. While they only show a part of the on-going research activities in Europe, we hope that these proceedings provide inspiration both for further research and for implementation in practice
A note on Wadge degrees
No full textFor pertinent definitions see published works of the Cabal Seminar. It has been shown by D. A. Martin that under the assumption of AD, Wadge degrees are well ordered; for Wadge degrees of Δ^(1)_(2n) sets Δ^(1)_(2n)-determinacy suffices. Martin has also proved (using AD) that the length of the well ordering of Δ^(1)_(2n) Wadge degrees is exactly δ^(1)_(2n+1). The author gives an alternate proof of this fact, using only Δ^(1)_(2n)-determinacy
Cluster randomized trial in the general practice research database: 2. Secondary prevention after first stroke (eCRT study): study protocol for a randomized controlled trial.
Full text linkBACKGROUND: The purpose of this research is to develop and evaluate methods for conducting pragmatic cluster randomized trials in a primary care electronic database. The proposal describes one application, in a less frequent chronic condition of public health importance, secondary prevention of stroke. A related protocol in antibiotic prescribing was reported previously. METHODS/DESIGN: The study aims to implement a cluster randomized trial (CRT) using the electronic patient records of the General Practice Research Database (GPRD) as a sampling frame and data source. The specific objective of the trial is to evaluate the effectiveness of a computer-delivered intervention at enhancing the delivery of stroke secondary prevention in primary care. GPRD family practices will be allocated to the intervention or usual care. The intervention promotes the use of electronic prompts to support adherence with the recommendations of the UK Intercollegiate Stroke Working Party and NICE guidelines for the secondary prevention of stroke in primary care. Primary outcome measure will be the difference in systolic blood pressure between intervention and control trial arms at 12-month follow-up. Secondary outcomes will be differences in serum cholesterol, prescribing of antihypertensive drugs, statins, and antiplatelet therapy. The intervention will continue for 12 months. Information on the utilization of the decision-support tools will also be analyzed. DISCUSSION: The CRT will investigate the effectiveness of using a computer-delivered intervention to reduce the risk of stroke recurrence following a first stroke event. The study will provide methodological guidance on the implementation of CRTs in electronic databases in primary care. TRIAL REGISTRATION: Current Controlled Trials ISRCTN35701810
