  • METHODS: In this international, multicentre, randomised, open-treatment trial, patients were allocated to 0ยท9 mg/kg intravenous recombinant tissue plasminogen activator (rt-PA) or to control. (biomedsearch.com)
  • METHODS: Data on the frequency of angina attacks, short-acting nitrate consumption, and heart rate were pooled from 5 randomized trials in patients with stable angina pectoris receiving 5, 7.5, or 10 mg of ivabradine b.i.d. for 3 or 4 months. (biomedsearch.com)
  • compression
  • It depends most on the listener's familiarity with digital artifacts, their awareness that artifacts may in fact be present, and to a lesser extent, the compression method, bit-rate used, input characteristics, and the listening/viewing conditions and equipment. (wikipedia.org)
  • All lossless data compression methods are transparent, by nature. (wikipedia.org)
  • scientific method
  • Would a double Blind scientific method be useful to determine if Ghosts exist? (yahoo.com)
  • Blind experiments are an important tool of the scientific method, in many fields of research - medicine, psychology and the social sciences, natural sciences such as physics and biology, applied sciences such as market research, and many others. (wikipedia.org)
  • citation needed] Various scientific processes, such as peer reviews, the discussions at scientific conferences, and other meetings where scientific results are presented, are part of a social process whose purpose is to strengthen the objective aspect of the scientific method. (wikipedia.org)
  • Experiments are an important tool of the scientific method. (wikipedia.org)
  • The process of the scientific method involves making conjectures (hypotheses), deriving predictions from them as logical consequences, and then carrying out experiments or empirical observations based on those predictions. (wikipedia.org)
  • Though the scientific method is often presented as a fixed sequence of steps, it represents rather a set of general principles. (wikipedia.org)
  • Robert Nola and Howard Sankey remark that "For some, the whole idea of a theory of scientific method is yester-year's debate, the continuation of which can be summed up as yet more of the proverbial deceased equine castigation. (wikipedia.org)
  • The DNA example below is a synopsis of this method The scientific method is the process by which science is carried out. (wikipedia.org)
  • As in other areas of inquiry, science (through the scientific method) can build on previous knowledge and develop a more sophisticated understanding of its topics of study over time. (wikipedia.org)
  • Though the scientific method is often presented as a fixed sequence of steps, these actions are better considered as general principles. (wikipedia.org)
  • experiment
  • In 1799 the British chemist Humphry Davy performed another early blind experiment. (wikipedia.org)
  • One of the first essays advocating a blinded approach to experiments in general came from Claude Bernard in the latter half of the 19th century, who recommended splitting any scientific experiment between the theorist who conceives the experiment and a naive (and preferably uneducated) observer who registers the results without foreknowledge of the theory or hypothesis being tested. (wikipedia.org)
  • bias
  • It is understood that bias may be intentional or unconscious, thus no dishonesty is implied by blinding. (wikipedia.org)
  • Single-blind describes experiments where information that could introduce bias or otherwise skew the result is withheld from the participants, but the experimenter will be in full possession of the facts. (wikipedia.org)
  • Single-blind experimental design is used where the experimenters either must know the full facts (for example, when comparing sham to real surgery) and so the experimenters cannot themselves be blind, or where the experimenters will not introduce further bias and so the experimenters need not be blind. (wikipedia.org)
  • study
  • One of the major reasons research like the old Duke-Rhine telepathy study is flawed is because they didn't follow double-blind procedures. (yahoo.com)
  • For example, neither the researchers nor the participants knowing which item was hidden in the envelope or box might be a double-blind type of study for testing somebody's psychic prediction abilities. (yahoo.com)
  • differences
  • Two prominent differences in performance between the two methods are the bandwidth and the signal-to-noise ratio (S/N). The bandwidth of the digital system is determined, according to the Nyquist frequency, by the sample rate used. (wikipedia.org)
  • Terms
  • The terms blind (adjective) or to blind (transitive verb) when used in this sense are figurative extensions of the literal idea of blindfolding someone. (wikipedia.org)
  • studies
  • Double blind studies are great for testing something such as paranormal abilities (e.g., telekinesis, psychic powers, etc. (yahoo.com)
  • different
  • The ABX method is normally used, with a null hypothesis that the samples tested are the same and with an alternative hypothesis that the samples are in fact different. (wikipedia.org)
