ANN-based sub-surface monitoring technique exploiting electromagnetic features extracted by GPR signals

Abstract. In this work we consider the problem of determining the dielectric characteristics of sub-surface layers by means of GPR systems. In particular, a suitable electromagnetic feature (the RΓ parameter), strictly related to the geophysical parameters of the scenario, is first extracted from the GPR e.m. signal and then fed to an artificial neural network (ANN) in order to derive the dielectric permittivity of the sub-surface layer

Abdominal nodal localization of Castleman's disease: report of a case.

Abstract Introduction Castleman's disease (CD) is a rare benign disorder that may grow in any area where lymphoid tissue is normally present but the most frequent site is mediastinum (67%); the abdomen is rarely affected by this pathology. In the pathogenesis of CD an important role could be played by HHV-8. Diagnosis is difficult and the diagnostic certainty is obtained only by histological examination. For this disease there is no gold-standard treatment. Case report We report the case of a woman of 33 years of age affected by a rare form of abdominal nodal localization of Castleman's Disease for which the patient underwent surgery. Conclusion CD must be included in the differential diagnosis of retroperitoneal tumors even though the definitive diagnosis can only be achieved by histological and immunohistochemical examination. In the case of single location, the treatment of choice is surgical removal

Fostering Self-Authorship and Changemaking: Insights from a Social Entrepreneurship Practicum

The question we are explore in this paper is how a collaboration between a practicum-based course and a social enterprise encourages students to examine, discuss, and apply complex social justice concepts and frameworks. We also investigate how this fosters in them a sense of self as changemaker, a form of self-authorship that includes the confidence to tackle justice issues in collaborative and practical ways. Applying the framing of Baxter Magolda’s Learning Partnerships Model, we first describe our experiential pedagogical practice and then illustrate outcomes by drawing exemplars from student reflections. These reflections confirm that a community-based learning practice can support students to become changemakers able to analyze the systemic forces that give rise to injustices, engage in honest dialogue to understand multiple perspectives, cultivate trusting relationships across differences of identity and experience, and feel confidence in themselves and others to create meaningful change toward a more just world
