The Summation of One Class of Infinite Series  [PDF]
Jonathan D. Weiss
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.517269
Abstract: This paper presents closed-form expressions for the series, \"\", where the sum is from n = 1 to n = ∞. These expressions were obtained by recasting the series in a different form, followed by the use of certain relationships involving the elliptical nome. Among the values of x for which these expressions can be obtained are of the form: \"\" and \"\", where l is an integer between ∞ and ∞. The values of λ include 1,\"\",\"\"and 3. Examples of closed-form expressions obtained in this manner are first presented for \"\", \"\", \"\", and \"\". Additional examples are then presented for \"\", \"\", \"\", and \"\". This undertaking was prompted by the author’s work on an electrostatics boundary-value problem related to the van der Pauw measurement technique of electrical resistivity. The presence of this series for x = \"\" in the solution of that problem and its absence from any compendium of infinite series that he consulted led to this work.
A Hypothesis Concerning the Effect of Schedule on the Pattern of 5-Fluorouracil Toxicity  [PDF]
Arthur J. Weiss
Journal of Cancer Therapy (JCT) , 2015, DOI: 10.4236/jct.2015.63028
Abstract:

The significant effect that scheduling has upon the severity and types of drug toxicity has been known for many years. Evidence is available demonstrating that the schedule chosen will substantially effect the relative distribution of drug to various target organs. It has been shown that a likely cause for this with doxorubicin is that the efficiency of the various enzyme complexes responsible for disposing of the drug can be affected by scheduling. We believe a similar process can explain the marked effect that scheduling has on the pattern of 5-fluorouracil toxicity and present both clinical and computer data to illustrate this.

Lead, Manganese, and Methylmercury as Risk Factors for Neurobehavioral Impairment in Advanced Age
Bernard Weiss
International Journal of Alzheimer's Disease , 2011, DOI: 10.4061/2011/607543
Abstract: Contamination of the environment by metals is recognized as a threat to health. One of their targets is the brain, and the adverse functional effects they induce are reflected by neurobehavioral assessments. Lead, manganese, and methylmercury are the metal contaminants linked most comprehensively to such disorders. Because many of these adverse effects can appear later in life, clues to the role of metals as risk factors for neurodegenerative disorders should be sought in the exposure histories of aging populations. A review of the available literature offers evidence that all three metals can produce, in advanced age, manifestations of neurobehavioral dysfunction associated with neurodegenerative disease. Among the critical unresolved questions is timing; that is, during which periods of the lifespan, including early development, do environmental exposures lay the foundations for their ultimate effects?
Review of "Haldane, Mayr, and Beanbag Genetics" by Krishna Dronamraju
Ken Weiss
Investigative Genetics , 2011, DOI: 10.1186/2041-2223-2-19
Abstract: The context is the discussion of the formative years of 20th-century genetics and evolutionary theory about how reductionist one can be to capture the nature of evolution and genetics effectively. The context is debate between Haldane and Ernst Mayr, whom the author also knew, about the relevance of the then-new field of population genetics. The phrase 'beanbag genetics' was coined in the mid-20th century to refer to an alleged view that evolution could be understood one gene at a time, each independently on its own terms, and that selection worked gene-by-gene. Mayr used the phrase to resist such reductionism, arguing that organisms rather than genomes are important, because they are the result of complex interactions among genes. The discussion took place as part of the formation of the 'modern synthesis' that united Darwin's and Mendel's thinking, a synthesis which began around 1920 and developed during the subsequent generation. Only by around the 1960s was it somewhat displaced theoretically by other issues, such as 'non-Darwinian' neutralism, and by a focus on the actual nature of genes and genomes that was being revealed.Dronamraju argues that the disagreements between Mayr and Haldane were substantial, if gentlemanly, and their views were never as far apart as caricatures of them suggested. As Dronamraju points out, though their studies were largely single-gene-focused, population geneticists indeed considered multilocus interactive models, and their debate was not whether genes interact but how important nonadditive effects are in understanding the fate of variants at a single gene. The issues are alive today in the context of extensive sequence data, though few today pay much attention to these more theoretical details, being concerned instead, rightly or wrongly, with immediate analytical challenges rather than the role of history in framing our views today.Dronamraju presents the arguments of the time and some of the subsequent views of and commentaries

Weiss PF
Adolescent Health, Medicine and Therapeutics , 2012, DOI: http://dx.doi.org/10.2147/AHMT.S25872
Abstract: gnosis and treatment of enthesitis-related arthritis Review (2568) Total Article Views Authors: Weiss PF Published Date June 2012 Volume 2012:3 Pages 67 - 74 DOI: http://dx.doi.org/10.2147/AHMT.S25872 Received: 06 March 2012 Accepted: 17 April 2012 Published: 05 June 2012 Pamela F Weiss Division of Rheumatology and Center for Pediatric Clinical Effectiveness, The Children's Hospital of Philadelphia, Departments of Pediatrics and Center for Clinical Epidemiology and Biostatistics, University of Pennsylvania School of Medicine, Philadelphia, PA, USA Abstract: Juvenile idiopathic arthritis (JIA) is a chronic, inflammatory disease of unknown etiology. The enthesitis-related arthritis (ERA) JIA category describes a clinically heterogeneous group of children including some who have predominately enthesitis, enthesitis and arthritis, juvenile ankylosing spondylitis, or inflammatory bowel disease-associated arthropathy. ERA accounts for 10%–20% of JIA. Common clinical manifestations of ERA include arthritis, enthesitis, and acute anterior uveitis. Axial disease is also common in children with established ERA. Treatment regimens for ERA, many of them based on adults with rheumatoid arthritis and ankylosing spondylitis, include the use of nonsteroidal anti-inflammatory drugs, disease-modifying antirheumatic drugs, and biologic agents either individually or in combination.
User Frustrations as Opportunities
Michael Weiss
Technology Innovation Management Review , 2012,
Abstract: User frustrations are an excellent source of new product ideas. Starting with this observation, this article describes an approach that entrepreneurs can use to discover business opportunities. Opportunity discovery starts with a problem that the user has, but may not be able to articulate. User-centered design techniques can help elicit those latent needs. The entrepreneur should then try to understand how users are solving their problem today, before proposing a solution that draws on the unique skills and technical capabilities available to the entrepreneur. Finally, an in-depth understanding of the user allows the entrepreneur to hone in on the points of difference and resonance that are the foundation of a strong customer value proposition.
Economics of Software Product Development Collectives
Michael Weiss
Technology Innovation Management Review , 2011,
Abstract: Where software product development occurs is shifting from single companies to groups or collectives of companies. In this article, we retrace the evolution of how software product development is organized and then offer insights into the economic motivation for collectives, which will be relevant to companies considering joining a software product development collective. Building on the literature on software product line economics, we identify three factors affecting the economics of collectives (level of contribution, number of members, and diversity of use), and develop a model that links those factors to three economic outcomes (time, quality, and cost). This model can be used by potential members when deciding whether or not to join a collective.
Schamachi/ amax in 1683/1684 – Engelbert Kaempfer’s Intercultural Contacts
Lothar Weiss
Khazar Journal of Humanities and Social Sciences , 2011,
Abstract: The traveller Engelbert Kaempfer, a Christian German in Swedish diplomatic service, here in Schamachi, comes into real contact with a Muslim culture for the first time. As an academically educated physician he makes profitable use of his profession, as with Nawi Jusbascy, probably a born Azerbaijani, Mohammed Hossein and probably Martiros, perhaps Hafi Saburjan, too. As a Christian living in Schamachi within the Armenian quarter he meets other Christians, the Priest Arakhel, the already mentioned Martiros and maybe Hafi Saburjan. Besides the Armenian priest Arakhel he meets a cleric of another religion, Maheb Aali, the Muslim Molla, probably a born Azerbaijani and having lived there in Schamachi. As a diplomat he makes good contacts with diplomats of other nations, like Mohammed Hossein, a Persian and envoy to Poland, and esspecially with his friend Christophorov, the Greek in Russian service. And there are contacts with a military background, too, with the already-mentioned captain Nawi, and with . if correctly identified . the ghulam Ali Kuli Chan, possibly a born Georgian and all his life in Persian service, as commander-in-chief under two Shahs, one of the most powerful men in Persia and now, 1684, governor of the province of Shirvan.On the one hand all these Schamachi contacts were surely a good start for Kaempfer.s later cultural experiences and his attempts to understand foreign cultures, such as India, Siam and Japan. On the other hand this shows above else that, during those days, Schamachi was a meeting point between great empires and an important place of intercultural contacts at the European-Asian border.
