The 'factorization method', discovered by Professor Kirsch, is a relatively new method for solving certain types of inverse scattering problems and problems in tomography. The text introduces the reader to this promising approach and discusses the wide applicability of this method by choosing typical examples.
La agencia de noticias ANCLA es un modelo de resistencia cultural. Impulsada por Rodolfo Walsh, la agencia dependió del Departamento de Informaciones de Montoneros. Fue una herramienta política contra la dictadura militar. El poeta Vicente Zito Lema escribió en el prólogo que ANCLA “es un momento fundante para una épica de resistencia en el ámbito de la comunicación, que por su trágica magnificencia, por su desmesura ética merece asociarse a momentos culminantes del humanismo”. Este libro de Natalia Vinelli se reedita en un tiempo sombrío. Su versión original se publicó en 2000 bajo el sello de la mítica editorial La Rosa Blindada. Por primera vez se traduce al inglés. Son páginas movilizadoras. Porque, como decía Zito Lema, sobre Walsh, sobre Vinelli, “en tiempos bravíos, el silencio mata y la palabra quema”.
Struggling for Time examines how time is used as a mechanism of control by the Israeli state and a site of mundane resistance among Palestinian agriculture professionals. Natalia Gutkowski unpacks power structures to show how a settler society lays moral claim on indigenous time through agrarian environmental policies, science, technologies, landscapes, and bureaucracy. Shifting the analysis of Israel/Palestine from land and space to time, she offers new insight into the operation of power in agrarian environments and develops a contemporary framework to understand land and resource grabs under temporal justifications. Traveling across both policymaking arenas and Palestinian citizens' agrarian fields, Gutkowski follows the multiple ways that state officials, agronomists, planners, environmentalists, and agriculturalists use time as a tool of collective agency. Through investigations of wetland drainage in Galilee, transformations in olive agriculture, sustainable agrarian development, and regulation of the shmita biblical commandment, the "year of release" for agricultural fields, this work highlights how Palestinian citizens' agriculture has become a site for the state to settle and mediate time conflicts to justify its existence. As Struggling for Time demonstrates, time politics will take on ever greater urgency as societies and governments plan for an uncertain future in our era of climate change.
Thoroughly researched, this study highlights the historical scholarship that is one of the lasting legacies of interwar Polish Jewry and analyses its political and social context. As Jewish citizens struggled to assert their place in a newly independent Poland, a dedicated group of Jewish scholars fascinated by history devoted themselves to creating a sense of Polish Jewish belonging while also fighting for their rights as an ethnic minority. The political climate made it hard for these men and women to pursue an academic career; instead they had to continue their efforts to create and disseminate Polish Jewish history by teaching outside the university and publishing in scholarly and popular journals. By introducing the Jewish public to a pantheon of historical heroes to celebrate and anniversaries to commemorate, they sought to forge a community aware of its past, its cultural heritage, and its achievements---though no less important were their efforts to counter the increased hostility towards Jews in the public discourse of the day. In highlighting the role of public intellectuals and the social role of scholars and historical scholarship, this study adds a new dimension to the understanding of the Polish Jewish world in the interwar period.
The main purpose of this book is to present emerging neuroimaging data in order to define the role of primary and secondary structural and hemodynamic disturbances in different phases of traumatic brain injury (TBI) and to analyze the potential of diffusion tensor MRI, tractography and CT perfusion imaging in evaluating the dynamics of TBI. The authors present a new MRI classification of brain stem and hemispheric cortical/subcortical damage localization that is of significant prognostic value. New data are provided regarding the pathogenesis and dynamics of diffuse and focal brain injuries and qualitative and quantitative changes in the brain white matter tracts. It is shown that diffuse axonal injury can be considered a clinical model of multidimensional “split brain” with commissural, association and projection fiber disorders. The book will be of interest for neuroradiologists, neurosurgeons, neurologists and others with an interest in the subject.
The factorization method is a relatively new method for solving certain types of inverse scattering problems and problems in tomography. Aimed at students and researchers in Applied Mathematics, Physics and Engineering, this text introduces the reader to this promising approach for solving important classes of inverse problems. The wide applicability of this method is discussed by choosing typical examples, such as inverse scattering problems for the scalar Helmholtz equation, a scattering problem for Maxwell's equation, and a problem in impedance and optical tomography. The last section of the book compares the Factorization Method to established sampling methods (the Linear Sampling Method, the Singular Source Method, and the Probe Method).
