Abstract	Expert system and neural network technology has recently matured to the point where it is often economically attractive to apply it in an industrial setting. This paper presents an overview of expert system and neural network technology, describes relevant applications in sensor fusion, diagnostics, and process control, and discusses factors which determine where to appropriately use each technology.

Abstract	Clinical and mammographic data of 1009 consecutive patients were correlated with histopathologic data of 1144 biopsy specimens of nonpalpable breast lesions to better define the presentation and biologic behavior of early breast cancer. Patients with malignant neoplasms (269 [24%] of 1144 specimens) were older (mean age, 62.1 years) than patients with benign lesions (mean age, 54.9 years). Furthermore, patients with invasive disease were older (mean age, 63.3 years) than patients with noninvasive disease (mean age, 58.5 years) with an overall increased risk of invasive cancer per year of 1.035. A 58% incidence of invasive cancer was detected for lesions characterized by calcifications, while the incidence of invasive cancer was 84% for isolated mass lesions (relative risk, 4.31 for masses). Isolated mammographic calcifications associated with cancer appeared in a younger population and were significantly associated with noninvasive ductal cancer. Breast cancer presenting as a mammographic mass appeared in an older group and was highly associated with the presence of invasive disease.

Abstract	We prospectively studied 239 consecutive patients who underwent breast biopsy for 277 nonpalpable lesions characterized by mammographic microcalcifications. Clinical and mammographic characteristics were correlated with histologic findings in an attempt to identify patients more likely to have early breast cancer. The distribution of clinical risk factors was equal between patients with benign or malignant outcomes. The predominant Wolfe pattern on mammography was P2 (38%); however, no relationship was observed between the Wolfe pattern and malignancy. A marked correlation was observed between malignancy and small lesions, more than 15 calcifications, and calcifications in a linear or branching pattern. Twenty-four percent (n = 67) of the biopsy specimens contained either ductal or lobular breast cancer. This study highlights the necessity of an aggressive approach toward suspicious calcifications found by mammography.

Abstract	We prospectively studied 718 women who underwent biopsy of the breast for suspicious, mammographically detected mammary lesions in an attempt to identify key clinical risk factors, as well as roentgenographic characteristics associated with the appearance of early carcinoma of the breast. Patients with a benign outcome had an average age of 55 years versus 63 years for patients with carcinoma of the breast. Seventy-six per cent of these patients had no previous history of mammary problems, 20 per cent had a positive family history for carcinoma of the breast, 58 per cent were premenopausal and 21 per cent had used birth control pills. Except for age (p less than 0.001), the distribution of clinical risk factors was equal among patients with benign or malignant outcomes. Suspicious mammographic findings included mass lesions (53 per cent), calcifications (36 per cent) and the association of both (11 per cent). The predominant Wolfe pattern on mammography was P1 (36 per cent). No relationship was observed between Wolfe pattern and malignant conditions. In this group of patients, mammography was poorly specific; however, the positive predictive value increased with age and is related to the age-specific prevalence of carcinoma of the breast. Eight hundred and twenty-five lesions were removed. Twenty-five per cent (n = 203) of the specimens taken at biopsy contained carcinoma. Stellate mass lesions were highly suggestive of a malignant growth (p less than 0.0001). No relationship between the size of the suspicious mammographic mass and the malignant lesion was observed. A marked correlation (chi-square test with Yate's correction) was observed between malignant tumor and lesions with a linear or branching pattern, more than 15 calcifications, or small sized calcifications. The presence of a mass with calcifications was associated with carcinoma in 34 per cent. The incidence of invasive carcinoma was much higher for mass lesions (81 per cent) than for suspicious calcifications (56 per cent) (p less than 0.0001).

Abstract	Measurements of multiplicity and transverse momentum fluctuations of charged particles were performed in inelastic p+p interactions at 20, 31, 40, 80 and 158 GeV/c beam momentum. Results for the scaled variance of the multiplicity distribution and for three strongly intensive measures of multiplicity and transverse momentum fluctuations \$\Delta[P_{T},N]\$, \$\Sigma[P_{T},N]\$ and \$\Phi_{p_T}\$ are presented. For the first time the results on fluctuations are fully corrected for experimental biases. The results on multiplicity and transverse momentum fluctuations significantly deviate from expectations for the independent particle production. They also depend on charges of selected hadrons. The string-resonance Monte Carlo models EPOS and UrQMD do not describe the data. The scaled variance of multiplicity fluctuations is significantly higher in inelastic p+p interactions than in central Pb+Pb collisions measured by NA49 at the same energy per nucleon. This is in qualitative disagreement with the predictions of the Wounded Nucleon Model. Within the statistical framework the enhanced multiplicity fluctuations in inelastic p+p interactions can be interpreted as due to event-by-event fluctuations of the fireball energy and/or volume.

Abstract	Results are presented on Omega production in central Pb+Pb collisions at 40 and 158A GeV beam energy. For the first time in heavy ion reactions, rapidity distributions and total yields were measured for the sum Omega(-) + Omega(+) at 40A GeV and for Omega(-) and Omega(+) separately at 158A GeV. The yields are strongly underpredicted by the string-hadronic UrQMD model but agree better with predictions from hadron gas models.

Abstract	Emission of pi+/-, K+/-, phi, and Lambda was measured in near-central C+C and Si+Si collisions at 158 AGeV beam energy. Together with earlier data for p+p, S+S, and Pb+Pb, the system-size dependence of relative strangeness production in nucleus-nucleus collisions is obtained. Its fast rise and the saturation observed at about 60 participating nucleons can be understood as the onset of the formation of coherent systems of increasing size.

Abstract	Results of resonance searches in the Xi(-)pi(-), Xi(-)pi(+), Xi;(+)pi(-), and Xi;(+)pi(+) invariant mass spectra in proton-proton collisions at sqrt[s]=17.2 GeV are presented. Evidence is shown for the existence of a narrow Xi(-)pi(-) baryon resonance with mass of 1.862+/-0.002 GeV/c(2) and width below the detector resolution of about 0.018 GeV/c(2). The significance is estimated to be above 4.2sigma. This state is a candidate for the hypothetical exotic Xi(--)(3/2) baryon with S=-2, I=3 / 2, and a quark content of (dsdsū). At the same mass, a peak is observed in the Xi(-)pi(+) spectrum which is a candidate for the Xi(0)(3/2) member of this isospin quartet with a quark content of (dsus[-]d). The corresponding antibaryon spectra also show enhancements at the same invariant mass.

Abstract	Production of Lambda and Antilambda hyperons was measured in central Pb-Pb collisions at 40, 80, and 158A GeV beam energy on a fixed target. Transverse mass spectra and rapidity distributions are given for all three energies. The Lambda/pi ratio at midrapidity and in full phase space shows a pronounced maximum between the highest BNL Alternating Gradient Synchrotron and 40A GeV CERN Super Proton Synchrotron energies, whereas the Lambda/pi ratio exhibits a monotonic increase.

Abstract	Neutral pion transverse momentum spectra were measured in p+C and p+Pb collisions at sqrt[S{NN}]=17.4 GeV at midrapidity (2.3 less than or approximately equal eta{lab} less than or approximately equal 3.0) over the range 0.7 less than or approximately equal p{T} less than or approximately equal 3.5 GeV/c. The spectra are compared to pi{0} spectra measured in Pb+Pb collisions at sqrt[S{NN}]=17.3 GeV in the same experiment. For a wide range of Pb+Pb centralities (N{part} less than or approximately equal 300), the yield of pi{0}'s with p{T} greater than or approximately equal 2 GeV/c is larger than or consistent with the p+C or p+Pb yields scaled with the number of nucleon-nucleon collisions (N{coll}), while for central Pb+Pb collisions with N{part}greater than or approximately equal 350, the pi{0} yield is suppressed.
