No full textFew issues in the field of securities law have proved as controversial as the legitimacy and proper application of the implied private cause of action for securities fraud under Section 10(b) of the Securities Exchange Act of 1934 and its regulatory counterpart, Rule 10b-5. The Private Securities Litigation Reform Act of 1995 was expected by many observers to bring about sweeping changes in the implied private cause of action, which critics charge has been abused by overzealous litigants bringing frivolous lawsuits. In his timely article, Professor Fallone argues that most of the Private Securities Litigation Reform Act\u27s changes to the implied private cause of action are merely procedural in nature and fail to address the real problem: the scope of liability for securities fraud under Section 10(b) has been rendered incomprehensible by conflicting court decisions and is no longer consistent with the overall goals of the federal securities laws. The author calls for Congress to reassert control over the content of the implied private cause of action under Section 10(b) by codifying it.Professor Fallone begins with an overview of the most recent securities legislation and an explanation of why it does little to resolve the ambiguities surrounding the implied private cause of action. He then chronicles the history of the cause of action, describing its elements as they currently exist and how they have evolved over the years. The author then points out specific problems arising from the elements of the cause of action having been left up to the courts, and how the common-law process has resulted in an interpretation of the cause of action that is inconsistent with the overall goals of the federal securities laws. Finally, Professor Fallone recommends that Congress codify the cause of action employing a structuralist approach, a method of statutory construction which emphasizes consistency with the operating principles of a statutory scheme
Cause multiple di morte: primi risultati di un'analisi della mortalità degli anziani in Italia
No full textModelling interdependent urban networks in planning and operation scenarios
No full textWe propose a cross-domain methodology to model and evaluate efficiency indicators of a Medium Voltage/Low Voltage (MV/LV) smart grid and its SCADA, interdependent, at physical layer and ICT layer, with water and gas urban networks. Models account the interdependency among the networks, a) adding, when possible, to the main sources of each network, sources belonging to the other networks; b) looking at the active components of water and gas networks energized by the electrical grid and c) considering ICT, which represents a common means, supporting and interconnecting SCADA devices of all the networks. Models use domain simulators to faithfully represent each physical network, and transversal simulators, to represent together the three interdependent physical networks and their SCADA systems. Models built by domain simulators are used to validate models built by transversal simulators. Efficiency indicators, and particularly, the Quality of Service of each network, are predicted along planning and operation scenarios. © 2014 DIME UNIVERSITÀ DI GENOVA

3-D automatic anatomy-based image registration in portal imaging
No full textA three dimensional, automatic, anatomy-based system for portal verification has been developed based on an FFT implementation of Pearson's correlation coefficient (PCC). The PCC requires no anatomy or point-pair identification, is robust when encountering changes in scaling and shifts in image amplitudes and requires no priori knowledge of the anatomy, which makes it an ideal candidate for portal-to-DRR image registration. Features for matching are selected from orthogonal portal images and compared to the corresponding megavoltage DRR. The position of the highest correlation value is then converted into beam-to-patient geometry and compared with the actual patient setup. By continuously generating DRRs, the system is capable of verifying translation errors, in-plane rotation and out-of-plane rotation errors. The mean accuracy of translation and rotation registrations tests were 0.58 mm and 0.79° respectively for DRR-to-DRR matching, and 1.22 mm and 1.31° respectively for portal-to-DRR matching
Construction and dosimetric evaluation of compensators for intensity modulated beams
No full textWe investigated the feasibility of constructing compensators for intensity modulated beams. The average uncertainty in the constructed compensator thickness was +/-0.3 mm. It was found that the beam hardening effect was significant, and can lead to an error of 6.2% in the transmission, for 6 cm of lead alloy in the beam. The maximum scatter contribution to the measured fluence was 19.8% for a 20 x 20 cm2 field size, and 6 cm of lead alloy in the beam. The compensators were constructed using a simple attenuation model. For a simple wedge-step compensator there was a maximum deviation of 6% between the measured and our predicted fluence profile. For simple compensators this deviation can be attributed to scatter according to the scatter analysis introduced. The maximum deviation between the measured and predicted fluence, for fluence files derived from a commercial inverse treatment planning system was slightly higher at 7%. This is because other factors such as penumbra and scatter from neighboring modulations must be considered for each compensator individually
