“…In practice, however, the resolution measure should be computed using a point spread function that best models the acquired data. For example, in the presence of refractive index mismatches between sample, immersion medium, etc., the Gibson-Lanni model [13] or a vectorial model (e.g., [14,15]) might be more suitable.…”

“…It also demonstrates that our theoretical framework is a general one that can accommodate any realization of the image detection process. For example, the photon detection rates Λ 1 and Λ 2 of the two objects can be modeled as constants or time-varying functions, and the image functions q z 01 ,1 and q z 02 ,2 can correspond to image models of any objects including, for instance, point spread functions based on scalar or vectorial diffraction models (e.g., [13][14][15]).…”

“…For an image where additive Gaussian noise was present, potentially along with additive Poisson noise, the maximum likelihood estimation was realized by maximizing the loglikelihood function (15) where for k = 1, …, N p , z k = S θ,k + B k + W k if Poisson noise is also present, or z k = S θ,k + W k if not, and p θ,k (z k ) is the probability density function of z k given by Eq. 12, with μ θ (k, t) given by Eq.…”

“…We note that in the software implementation of the maximum likelihood estimator, we minimize the negative of the log-likelihood functions of Eqs. (14) and (15). Also, for data which were either noise-free (data set 1) or contained only additive Poisson noise (data sets 2 and 6), the term − ln(z k !)…”

A resolution measure for three-dimensional microscopy

A three-dimensional (3D) resolution measure for the conventional optical microscope is introduced which overcomes the drawbacks of the classical 3D (axial) resolution limit. Formulated within the context of a parameter estimation problem and based on the Cramer-Rao lower bound, this 3D resolution measure indicates the accuracy with which a given distance between two objects in 3D space can be determined from the acquired image. It predicts that, given enough photons from the objects of interest, arbitrarily small distances of separation can be estimated with prespecified accuracy. Using simulated images of point source pairs, we show that the maximum likelihood estimator is capable of attaining the accuracy predicted by the resolution measure. We also demonstrate how different factors, such as extraneous noise sources and the spatial orientation of the imaged object pair, can affect the accuracy with which a given distance of separation can be determined.

Group Sex as Play

Drawing on ethnographic and interview data collected from the United States and Finland on lifestyle (“swinging”) events, this article explores the implicit and explicit rules influencing negotiations for group sex as a type of play. Participants maintain a sense of freedom and spontaneity while acting within situational constraints—ethical expectations, preexplicated rules, implicit rules, and complex negotiations that occur during the play itself either openly or more subtly. Because it has implications for the participants’ everyday lives, lifestyle group sex is a phenomenon on the border between games and adult play. Through an analysis of the rules and social contracts arising in group sex, we demonstrate how participants learn to read interactions at group sex events in the way that players learn game systems and how they can and do become “good players” in such situations.

Purpose – The purpose of this paper is to present findings on the way in which self-identified sadomasochist apply their information literacy skills, and to analyse those applications in the context of existing research on information literacies (IL). Design/methodology/approach – The paper is based on the author’s two decades of ethnographic work within a national-level sadomasochist community, supplemented by interviews with 30 practitioners and an extensive literature survey. Findings – Sadomasochists avoid the social stigma associated with their activities by developing highly refined ILs. Central among these is the ability to learn from other practitioners by reading and interpreting their actions as “texts.” They furthermore stockpile potentially useful information for later use. Their ILs not only make sadomasochists more skilled in their practices, but also provide them with safety. Originality/value – By examining its subject community, the paper develops the ideas of embodied information literacy, currently strongly associated with workplace learning, to the hobby and lifestyle sectors, as it deals with a particularly corporeal set of ILs. This radical example allows scholars to conduct research on the ILs other communities of practice, in which the activities may be less obviously corporeal, but the literacies just as based on embodied interpretation and the reading of others’ activities as texts.
