Single Cell Impedance Cytometry for Identification and Counting of CD4 T-Cells in Human Blood Using Impedance Labels
No full textSingle cell microfluidic impedance cytometry has been used to identify cells at high speed, on the basis of their dielectric properties. However, there is no electrical analogue to a fluorescent label, meaning that it is not possible to identify subpopulations of cells. We demonstrate discrimination and enumeration of antigenically defined cell subpopulations using an alternating current (AC) impedance labeling method. Small antibody conjugated beads are mixed with cells and bind to the target population, changing the electrical properties of the target subset of cells. The principle of the technique is demonstrated by identifying and enumerating the CD4 T-lymphocyte subpopulation in human whole blood. The technique represents a simple method for detecting a subpopulation of cells within a heterogeneous mix. The impedance-based antibody identification method could form the basis of simple low-cost point of care diagnostic technologies
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
