  • What makes populations stabilize? What makes them fluctuate? Are populations in complex ecosystems more stable than populations in simple ecosystems? In 1973, Robert May addressed these questions in this classic book. May investigated the mathematical roots of population dynamics and argued-counter to most current biological thinking-that complex ecosystems in themselves do not lead to population stability.

  • Drawing appropriate defeasible inferences has been proven to be one of the most pervasive puzzles of natural language processing and a recurrent problem in pragmatics. This paper provides a theoretical framework, called stratified logic, that can accommodate defeasible pragmatic inferences. The framework yields an algorithm that computes the conversational, conventional, scalar, clausal, and normal state implicatures; and the presuppositions that are associated with utterances. The algorithm applies equally to simple and complex utterances and sequences of utterances. ...

  • Linguistic access to uncertain quantitative knowledge about physical properties is provided by d i m e n s i o n a l adjectives, e.g. long-short in the spatial and temporal senses, near-far, fast-slow, etc. Semantic analyses of the dimensional adjectives differ on whether the meaning of the differential comparative (6 cm shorter than) and the equative with factor term (three times as long as) is a compositional function of the meanings the difference and factor terms (6 cm and three times) and the meanings of the simple comparative and equative, respectively.

  • Introduction: As antiepileptics, phenytoin, mephenytoin, nirvanol and ethotoin are being used for treatments of grand mal and complex partial seizures. A iminostilbene derivative carbamazepine, phenobarbital (one of the barbiturates) and some benzodiazepines are also being well used as antiepileptics ( Figure 5.1). Poisoning cases due to accidental and suicidal ingestion of these antiepileptics were reported [1]. For analysis of antiepileptics, methods using HPLC [2–15], LC/MS [16], GC [17, 18] and GC/MS [19,20] were reported. Among them, HPLC methods are being used most commonly.

  • Even this figure doesn’t tell the whole story, however. Looking forward, many businesses realize their future competitiveness will depend on new business strategies and deeper insights that might require data that isn’t even being captured today. Projecting five years out, businesses shouldn’t be surprised if they want to store and analyze a rapidly growing data pool that is 100 times or more greater than the size of today’s data pool. And beyond size, the depth of analysis and complexity of business questions raised against the data can only be expected to grow.

  • This book aims to explain the basics of graph theory that are needed at an introductory level for students in computer or information sciences. To motivate students and to show that even these basic notions can be extremely useful, the book also aims to provide an introduction to the modern field of network science. Mathematics is often unnecessarily difficult for students, at times even intimidating.

  • In today’s competitive telecommunications environment, you are faced with the challenge of minimizing the cost and complexity of equipment at the network edge. To meet this need, the ADC Avidia Integrated Access Switch (IAS) combines the functionality of an ATM edge switch with a DSLAM. Then, through subtending, in which several systems are viewed and managed by a single management platform, deployment of Avidia allows you to lower equipment and network management costs.

  • A budget should include all projected expenses associated with a project, from refreshments at focus group discussions (FGDs) to staff salaries. When your project is complete, you can fill in actual budget costs and compare them with your projected figures for future planning. Figure 2 shows a sample budget for print, radio, and video materials. While not an exhaustive list, this sample includes the major expenses you might encounter in a typical materials development project.

  • Priority-setting approaches in the area of health have slighted SRH concerns. A disease-oriented approach to health priority setting has not recognized the importance of preventing unintended pregnancies. The consequences of these extend beyond the direct individual disability concerns to social participation, familial health and complex empowerment issues. Returns to investments in SRH are, therefore, difficult to assess and often omitted from policy dialogues.

  • However, instead of appropriately distributing risks, this process often concentrated risk in opaque and complex ways. Innovations occurred too rapidly for many financial institutions’ risk management systems; for the market infrastructure, which consists of payment, clearing and settlement systems; and for the nation’s financial supervisors. Securitization, by breaking down the traditional relationship between borrowers and lenders, created conflicts of interest that market discipline failed to correct.

  • Morphological lexica are often implemented on top of morphological paradigms, corresponding to different ways of building the full inflection table of a word. Computationally precise lexica may use hundreds of paradigms, and it can be hard for a lexicographer to choose among them. To automate this task, this paper introduces the notion of a smart paradigm. It is a metaparadigm, which inspects the base form and tries to infer which low-level paradigm applies. If the result is uncertain, more forms are given for discrimination.

  • There are many critical limits in the material available. For example, Senlis -- which sometimes tends to exaggerate the Taliban and Al Qa'ida challenge as part of its effort to increase aid and NATO/ISAF troop strength -- provides most of the available maps that give some idea of the progress in the fighting and the relative balance of Afghan Central government, Pakistani central government, NATO/ISAF, Taliban, and Al Qa'ida presence and influence. The end result is necessarily long and complex. The full brief runs over 200 pages.
