Discernible objects

Let us assume an unknown number of tiny fluorescent objects or molecules that are D < 200 nm apart. If they all have different colors, one can separate them with the right excitation or emission Alters. Discerning objects or molecules having distinct spectral characteristics is not really challenged by diffraction. The problem was to discern an arbitrary number of identical features at arbitrary distances < A/(2n sin a). [Pg.373]

However, finding out the position of an object with arbitrary precision is not the same as resolution, which is about separating similar objects at small distances. Localization per se cannot provide superresolution. This is also why, although it had been known and used for decades [109,110] and even routinely applied to single molecules [125,126], localization alone has not provided nanoscale images. (Note that in spite the use of localization in the 1980 s and earlier, near-field optical microscopy still seemed to be the only way to attain nanoscale resolution up to the early 1990 s.) Resolution clearly requires a criterion to discern objects or molecules, the simplest of which is bright vs. dark. ... [Pg.389]

Ziel, n. goal, aim, object, objective, end limit, boimdary mark, target term, time, zielbewusst, a. clear-sighted, discerning, zielen, v.i. aim (at), strive (for) tend (to). [Pg.529]

Nonetheless, many African American scientists. Just included, noted a curious pattern over the course of their careers that their work was cited more frequently in European than in American journals. This pattern of particularism was counter to the notion of objectivity. African American scientists were correct to assume that their relatively low rate of citation on one side of the Atlantic was related to their racial status. However, this is not to argue that European scientists were more accepting of African Americans. Rather they seemed to have had fewer ways than did white Americans of discerning race and, therefore, of acting on their prejudices. European scientists did not know the African American scientists personally, nor were they generally aware of predominantly black institutions (Manning, 1983, p. 332). [Pg.8]

At first glance, the spectral properties, absolute magnitudes (intrinsic luminosities) and shapes of the light curves of the majority of type la supernovas (SNIa) are remarkably similar. Only a few rather subtle photometric and spectrometric differences can be discerned from one object to another. [Pg.211]

The interpretation of the results from a clinical trial or series of trials denotes the process of discerning their clinical meaning or significance, or providing an explanation for the data under evaluation. The importance of interpretation lies both within the clinical trial and beyond it in the use to which the results will be put. Within the context of the trial itself, correct interpretation of the results will determine whether the objectives of the trial have been achieved and whether the hypothesis is proven, interpretation beyond the immediate clinical trial concerns comparisons with other studies, extrapolation to different populations and the impact on medical practice. [Pg.229]

But even at the thin atmosphere at high altitudes, atmospheric distortion limits the ability of telescopes to discern faint objects. Adaptive optics helps by sensing this distortion and instantly adjusting the optical properties of the instrument to counteract the harmful effects. The process must operate continually since air moves around, and the extent and nature of atmospheric distortion changes rapidly. [Pg.113]

The objective of this part of the chapter is to set managing and leading, proactivity and reactivity, in context so that you can discern how you might best utilize a project to develop yourself in all these aspects of managing effectively. [Pg.72]

When motivation became the object of scientific study, the same kind of exceptions to rational choice soon became apparent. Pavlov came up with the most robust solution—conditioned behavior, refined to conditioned motives, stated definitively in . H. Mowrer s two-factor theory (1947).1 In this form, Plato s passions seemed discernible in parametric research, and the ancient dual model was perpetuated. [Pg.210]

Dendrimer 15 was the object of a very interesting theoretical work by Amatore et al.55 discussing the possibility to observe a stochastic behavior of electrochemical events. In the limiting case of only one dendrimer 15 adsorbed on the electrode surface, the current measured in a chronoamperometric experiment would show a random and discontinuous succession of single electron transfer events, while for an array of 7800 dendrimers, corresponding to complete coverage of an electrode of 500 nm in radius, the stochastic nature of the phenomenon is no longer clearly discernable. [Pg.164]

As a man thru a window into a darken d house peering vainly wil see, always and easily, the glass surface and his own face mirror d thereon tho looking from another angle, or hooding his eyes he may discern some real objects within the room. [Pg.405]

To interpret the significance of the presence of ochre, one must first attempt to discern if the use of the material was practical or symbolic. Practical uses of ochre include application as a preservative in curing hides, as an adhesive for hafting stone tools, and as medicine. Even practical objects can have symbolic... [Pg.483]
