No full textDEVICE FOR MONITORING POSITION AND MOVEMENTS OF AN EYE, PARTICULARLY SUITABLE FOR OCULAR RADIOTHERAPY
No full textThe present invention is about a device for non-invasive monitoring of an eye position and ocular movements of a patient, comprising:
- a housing body (2) having at least one through opening (2a);
- a plurality of light sources (3) housed in said housing body (2);
- a plurality of sensor means (4) housed in said housing body (2);
- deflector means (6) for invisible radiation (RL) supplied, in use, by said plurality of light sources (3) and reflected by said eye (O) under examination;
- support means (8) that can be adjusted for said housing body (2);
- at least one program data processing and control unit (9). The support means (8) can be adjusted in such a way that the through opening (2a) of the housing body (2) can be placed at the eye (O) under examination so that the invisible radiation hits the eye (O) frontally.
The program data processing and control unit (9) is designed to calculate instant-by-instant the position and orientation of a suitable three-dimensional reference system integral with the eye with respect to a predetermined three-dimensional reference system

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
