Increased nuclear size, resulting in an increase in the relative proportion of nuclear to cytoplasmic sizes, is an important morphologic criterion for the evaluation of neoplastic and pre-neoplastic cells. This paper describes investigations into the suitability of automated image analysis for quantitating changes in nuclear and cytoplasmic cross-sectional areas in exfoliated cells from tracheas treated with carcinogen.Neoplastic and pre-neoplastic lesions were induced in the tracheas of Syrian hamsters with the carcinogen N-methyl-N-nitrosourea. Cytology samples were collected intra-tracheally with a specially designed catheter (1) and stained by a modified Papanicolaou technique. Three cytology specimens were selected from animals with normal tracheas, 3 from animals with dysplastic changes, and 3 from animals with epidermoid carcinoma. One hundred randomly selected cells on each slide were analyzed with a Bausch and Lomb Pattern Analysis System automated image analyzer.

Computer programs are now available in various laboratories for the indexing and simulation of transmission electron diffraction patterns. Although these programs address themselves to the solution of various aspects of the indexing and simulation process, the ultimate goal is to perform real time diffraction pattern analysis directly off of the imaging screen of the transmission electron microscope. The program to be described in this paper represents one step prior to real time analysis. It involves the combination of two programs, described in an earlier paper(l), into a single program for use on an interactive basis with a minicomputer. In our case, the minicomputer is an INTERDATA 70 equipped with a Tektronix 4010-1 graphical display terminal and hard copy unit.A simplified flow diagram of the combined program, written in Fortran IV, is shown in Figure 1. It consists of two programs INDEX and TEDP which index and simulate electron diffraction patterns respectively. The user has the option of choosing either the indexing or simulating aspects of the combined program.

Abstract:The frequency of ventricular premature beats (VPBs) has been related to the risk of mortality. However, little is known about the temporal pattern of occurrence of VPBs and its relationship to autonomic activity. Hence, we applied a general correlation measure, mutual information, to quantify how VPBs are generated over time. We also used mutual information to determine the correlation between VPB production and heart rate in order to evaluate effects of autonomic activity on VPB production. We examined twenty subjects with more than 3000 VPBs/day and simulated ran-( dom time series of VPB occurrence. We found that mutual information values could be used to characterize quantitatively the temporal patterns of VPB generation. Our data suggest that VPB production is not random and VPBs generated with a higher value of mutual information may be more greatly affected by autonomic activity.

This paper is an analysis of the most important mathematical aspects of medical diagnosis: logical probability, rationality and decision theory, gambling models, pattern analysis, hazy and fuzzy subsets theory and, finally, the stochastic inquiry process.

Contemporary communicative platforms welcome and accelerate a socio-anthropological mutation in which public opinion (Habermas, 1995) based on rational individuals and alphabetic culture gives way to a public emotion whose emotion, empathy and sociality are the bases, where it is no longer the reason that directs the senses but the senses that begin to think. The public spheres that are elaborated in this way can only be disjunctive (Appadurai, 2001), since they are motivated by the desire to transgress the identity, political and social boundaries where they have been elevated and restricted. The more the daily life, in its local intension and its global extension, rests on itself and frees itself from projections or infatuations towards transcendent and distant orders, the more the modern territory is shaken by the forces that cross it and pierce it. non-stop. The widespread disobedience characterizing a significant part of the cultural events that take place in cyberspace - dark web, web porn, copyright infringement, trolls, even irreverent ... - reveals the anomic nature of the societal subjectivity that emerges from the point of intersection between technology and naked life. Behind each of these offenses is the affirmation of the obsolescence of the principles on which much of the modern nation-states and their rights have been based. Each situation in which a tribe, cloud, group or network blends in a state of ecstasy or communion around shared communications, symbols and imaginations, all that surrounds it, in material, social or ideological terms, fades away. in the air, being isolated by the power of a bubble that in itself generates culture, rooting, identification: transpolitic to inhabit
