  • Genetic programming (GP) is a branch of Evolutionary Computing that aims the automatic discovery of programs to solve a given problem. Since its appearance, in the earliest nineties, GP has become one of the most promising paradigms for solving problems in the artificial intelligence field, producing a number of human-competitive results and even patentable new inventions. And, as other areas in Computer Science, GP continues evolving quickly, with new ideas, techniques and applications being constantly proposed....

  • Automatic extraction of collocations from large corpora has been the focus of many research efforts. Most approaches concentrate on improving and combining known lexical association measures. In this paper, we describe a genetic programming approach for evolving new association measures, which is not limited to any specific language, corpus, or type of collocation. Our preliminary experimental results show that the evolved measures outperform three known association measures.

  • Population Screening Mass genetic screening programs require tests of high enough sensitivity and specificity to be cost-effective. An effective screening program should fulfill the following criteria: that the tested disorder is prevalent and serious; that it can be influenced presymptomatically through lifestyle changes, screening, or medications; and that identification of risk does not result in undue discrimination or harm.

  • Two types of bills currently exist on the Serbian financial market: T-bills issued by the Ministry of Finance of the Republic of Serbia, and NBS bills, issued by the National Bank of Serbia. The main idea behind these financial instruments is to facil- itate the development of the financial market in Serbia. This is in accordance with the monetary policy of the National Bank of Serbia, but also an important aspect of the economic restructuring program. Nevertheless, both types of bills are currently trad- ed only on the primary market.

  • Learners enrolled in all healthcare training programs need to have a basic understanding of medical genetics so that they can successfully transition from students to clinicians. The field of medical genetics is advancing at a fast pace and is becoming increasingly integral to all aspects of medicine. This fact emphasizes the need for every practicing clinician and faculty member to develop an in-depth knowledge of the principles of human genetics, given that they are applicable to such a wide variety of clinical presentations.

  • DNA testing is performed by mutational analysis or linkage studies in individuals at risk for a genetic disorder known to be present in a family. Mass screening programs require tests of high sensitivity and specificity to be costeffective. Prerequisites for the success of genetic screening programs include the following: that the disorder is potentially serious; that it can be influenced at a presymptomatic stage by changes in behavior, diet, and/or pharmaceutical manipulations; and that the screening does not result in any harm or discrimination.

  • The GHI Strategy in Kenya identifies three broad focus areas: (1) health systems strengthening; (2) integrated service provision; and (3) creating awareness to create demand for available services. Applying these broad areas will potentially have their greatest measurable health benefits in substantially reducing unacceptably high rates of: (1) maternal, neonatal and child mortality and (2) morbidity and mortality from neglected tropical diseases.

  • Hydrogen peroxide (H2O2 ) is known to be a key player in apoptosis in ani-mals. The components and pathways regulating H2O2-induced programmed cell death in plants, however, remain largely unknown. In the present study, rice transgenic lines overexpressing Bcl-2, a human apoptotic sup-pressor, were obtained.

  • Approximately 75% of COPD cases are attributed to cigarette smoking (5). Occupation-related exposures may account for another 15% of COPD cases (6) and genetic factors, asthma, respiratory infections, and indoor and outdoor exposures to air pollutants also play a role (6,7). hus, COPD largely can be prevented. Prevention of COPD begins with reducing and/ or eliminating smoking initiation among teenagers and young adults and encouraging tobacco cessation among current smokers.

  • When it comes to advocating animal conservation, it is difficult to be convincing without becoming alarmist. The fact is, time is running out for many of the world’s animal species. Habitat loss, introduced species, overexploitation and pollution, all caused by human activities, combine with stochastic factors to place ever-increasing pressure on natural populations (Primack 2002).
