Does OO sync with the way we think?
No full textGiven that corrective-maintenance costs already dominate the software life cycle and look set to increase significantly, reliability in the form of reducing such costs should be the most important software improvement goal. Yet the results are not promising when we review recent corrective-maintenance data for big systems in general and for OO in particular-possibly because of mismatches between the OO paradigm and how we think
Multiple nucleic acid cleavage modes in divergent type III CRISPR systems
No full textCRISPR-Cas is an RNA-guided adaptive immune system that protects bacteria and archaea from invading nucleic acids. Type III systems (Cmr, Csm) have been shown to cleave RNA targets in vitro and some are capable of transcription-dependent DNA targeting. The crenarchaeon Sulfolobus solfataricus has two divergent subtypes of the type III system (Sso-IIID and a Cmr7-containing variant of Sso-IIIB). Here, we report that both the Sso-IIID and Sso-IIIB complexes cleave cognate RNA targets with a ruler mechanism and 6 or 12 nt spacing that relates to the organization of the Cas7 backbone. This backbone-mediated cleavage activity thus appears universal for the type III systems. The Sso-IIIB complex is also known to possess a distinct ‘UA’ cleavage mode. The predominant activity observed in vitro depends on the relative molar concentration of protein and target RNA. The Sso-IIID complex can cleave plasmid DNA targets in vitro, generating linear DNA products with an activity that is dependent on both the cyclase and HD nuclease domains of the Cas10 subunit, suggesting a role for both nuclease active sites in the degradation of double-stranded DNA targets.Peer reviewe

CSM Automated Confidence Score Measurement of Threat Indicators
No full textabstract: The volume and frequency of cyber attacks have exploded in recent years. Organizations subscribe to multiple threat intelligence feeds to increase their knowledge base and better equip their security teams with the latest information in threat intelligence domain. Though such subscriptions add intelligence and can help in taking more informed decisions, organizations have to put considerable efforts in facilitating and analyzing a large number of threat indicators. This problem worsens further, due to a large number of false positives and irrelevant events detected as threat indicators by existing threat feed sources. It is often neither practical nor cost-effective to analyze every single alert considering the staggering volume of indicators. The very reason motivates to solve the overcrowded threat indicators problem by prioritizing and filtering them.
To overcome above issue, I explain the necessity of determining how likely a reported indicator is malicious given the evidence and prioritizing it based on such determination. Confidence Score Measurement system (CSM) introduces the concept of confidence score, where it assigns a score of being malicious to a threat indicator based on the evaluation of different threat intelligence systems. An indicator propagates maliciousness to adjacent indicators based on relationship determined from behavior of an indicator. The propagation algorithm derives final confidence to determine overall maliciousness of the threat indicator. CSM can prioritize the indicators based on confidence score; however, an analyst may not be interested in the entire result set, so CSM narrows down the results based on the analyst-driven input. To this end, CSM introduces the concept of relevance score, where it combines the confidence score with analyst-driven search by applying full-text search techniques. It prioritizes the results based on relevance score to provide meaningful results to the analyst. The analysis shows the propagation algorithm of CSM linearly scales with larger datasets and achieves 92% accuracy in determining threat indicators. The evaluation of the result demonstrates the effectiveness and practicality of the approach.Dissertation/ThesisMasters Thesis Computer Science 201
Del CSM come sguardo e come volto delle questioni di genere nella magistratura
No full textIl saggio inquadra nelle loro dimensioni storiche e strutturali le questioni di genere nella magistratura, individuando da un lato la centralità del Csm nel proporre una lettura di tali questioni, ma anche riflettendo sulla composizione di genere del CSM. Prende quindi in esame le prospettive di riforma del CSM nella parte che affronta il nodo problematico della composizione del CSM dal punto di vista di genere, esaminando innanzitutto le proposte rivolte a definire "quote di partecipazione" e argomentandone la legittimità anche attraverso una lettura critica della giurisprudenza costituzionale in materia di quote (e dei suoi limiti). La riflessione si conclude segnalando la necessità di basarsi su una concezione dell'uguaglianza costituzionale gender sensitive e non gender blind e di ulteriormente sviluppare una approfondimento del rapporto tra prospettiva "duale" e qualità della rappresentanza.The essay deals with the significance of the CSM in relation to the gender issue in the judiciary. The CSM has been committed to this issue steadily and with awareness since the early nineties, not only producing and updating data on gender balance in the judiciary but also analyzing the gender implications and consequences of any organizational measure within the competence of the council (gender mainstreaming). The author also considers the historical and current composition of the CSM, as far as it offers a direct picture and representation of the lasting gender imbalance in the judiciary; different proposals on women’s or gender quotas in the CSM’s electoral system are critically reviewed from the perspective of women’s empowerment
La posizione costituzionale del Csm tra argomenti di ieri ed effettività dell’organo
No full textThe Italian High Council of the Judiciary (Consiglio Superiore della Magistratura, CSM) is the constitutional body which is called to guarantee the independence of the judiciary (more precisely, of that part of judiciary which have competence in ordinary jurisdiction).
This paper analyses and discusses the role of CSM, from the point of view of constitutional law and in a historical perspective, by two steps.
In the first part, the Author retraces the main doctrinal opinions about the constitutional position and functions of CSM, by reconstructing the debate around some key concepts or expressions like “self-government of judiciary”, “order” and “power” (referred to the judiciary as an institutional and professional body), “independence”, “guaranteeing functions” and “representative functions”.
In the second part, the interpretative model of CSM’s role, which the Author has defined by the previous theorical analysis, is discussed in the light of effective experience of this constitutional body and, especially, of the evolution of its (gradually increasing) regulative functions.
In the conclusion of the paper, the Author reflects on the relation between the expansion of CSM’s regulative functions and the spread of jurisdiction towards legislature, expressing also some suggestion to maintain a correct balance between judiciary and political power
SCEC Community Stress Model (CSM)
No full textThe SCEC Community Stress Model (CSM) is a group of models of stress and stressing rate within the southern California crust and lithosphere, compiled by the CSM Working Group of the Southern California Earthquake Center (SCEC).
“Stress” models are models of the 3-D symmetric stress tensor (6 components), describing the forces present within a continuous volume. “Stressing rate” models are models of how the 3-D stress tensor changes over time, for example due to stress accumulating along a tectonic plate boundary.
The CSM is one of several SCEC Community Models, but differs in that it does not attempt to provide a single consensus model of stress or stressing rate. Instead, the intention is to compile a set of models of stress and stressing rate. The current version of the CSM includes 11 distinct models: 6 of stress, and 5 of stressing rate. The model techniques, assumptions, and input datasets vary, so no two models provide the exact same result. Table 1, in the README file, provides a summary of some of the basic attributes of each model contribution. In some cases, the contributed models have been published in a peer reviewed journal. In other cases, the methods or datasets were previously published in a peer reviewed journal, but the exact contributed model is not published.
For the six stress models, the orientation of the stress tensor is mostly derived from the inversion of earthquake focal mechanisms. Three of the models are based solely on earthquake focal mechanisms, and thus do not provide information on stress magnitude. One model provides an estimate of the deviatoric stress required to support existing topography. Two models provide an estimate of the full absolute stress tensor, based on forward physics-based modeling of the tectonic loading of the southern California fault system. Note that even when sampled “on” a major fault surface, these model values should be regarded as estimates of stress in the adjacent continuum rather than estimates from “within” fault gouge zones.
The five stressing rate models are mostly based on kinematic or mechanical models constrained by geodetic data. Some are based on estimates of velocity field or strain rate that are then translated into stressing rate. Others involve forward physics-based modeling of tectonic loading of the fault system, but focus on deriving stressing rate rather than the absolute stress tensor.
Each of the models was contributed by an author or group of authors, the earliest in 2012, the most recent in 2017. Values in the crust (≤ 25 km depth) are reported for a uniform grid of latitude and longitude points, covering southern California at a resolution of ~2 km (0.0180º latitude, 0.0217º longitude), for a total of 72,325 unique points. Values in the deeper lithosphere (≥ 50 km) are reported for a uniform grid with a resolution of ~5 km (0.0450º latitude, 0.0543º longitude), for a total of 11,493 unique points. Depths are reported every 2 km from 1 km to 25 km depth, and then every 25 km to 100 km depth, for a total of 16 unique depths. Points that lie outside the defined volume for a particular model, given its assumptions and available data, are omitted from that model’s file.
The model contributions include the 6-component cartesian stress tensor (in East, North, Up, tension positive) at each grid point, and then several values calculated from the tensor components that describe different aspects of the orientation or magnitude of the 3-D tensor. For visualization of these models, see the CSM web viewer on the SCEC CSM homepage, https://www.scec.org/research/csm.
From 2012 - 2016, the CSM working group undertook a series of comparison exercises to understand where the models agree and disagree about the orientation and magnitude of stress and stressing rate. Broadly, stress models tend to agree in orientation but disagree about magnitude. Stressing rate models tend to agree along major fault segments, but disagree in secondary fault or off-fault areas.

Effect of Cutter Soil Mixing (CSM) method and curing pressures on the tensile strength of a treated soft clay
No full textAbstractThis study presents a set of laboratory experiments to investigate the effect of Cutter Soil Mixing (CSM) method and curing pressures on the tensile strength of a soft clay treated with Air Cooled Blast Furnace Slag (ACBFS) and Industrial Hydrated Lime (IHL). High productivity, minimum vibration, using the in-situ soil as construction material, and high level of quality control are some of the main benefits of CSM method. Three different slurries containing various percentages of ACBFS and IHL were mixed with saturated soft clay due to CSM method to enhance its tensile strength and make it suitable for the construction of deep CSM panels. To simulate high pressure due to the self-weight of the deep CSM panels in the field, a number of high pressure curing devices were designed and built in the laboratory and used for 28 and 56 day pressurised curing of the treated samples. Then an indirect tensile strength test was performed on the treated samples to investigate the effect of mixing method, ACBFS-IHL content, curing pressure and curing time on the tensile strength of the treated material. Finally, X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) analysis were conducted to investigate the microstructural and properties of the treated clay. The outcomes demonstrate that using CSM method and curing pressures along with ACBFS-IHL as a chemical stabiliser, increases the tensile strength of treated soft clay up to 35 times, which is significantly higher than the use of chemical stabiliser alone. Moreover, the microstructural analysis results revealed that the main hydration products in the clay treated with ACBFS-IHL is gismondine (C–A–S–H) which is also considered to be responsible for the higher tensile development.Abstract

CSM e decadenza: tra interpretazione e riscrittura della Costituzione
No full textThe essay critically analyses the decision of the Italian Superior Counsel for Judicial
Officers (Consiglio Superiore della Magistratura – CSM) regarding the termination of one of its members
due to his (mandatory) retirement from judicial office. The author focuses in particular on the identification
of the nature and function of the Counsel according to the relevant provisions of the Italian Constitution.
In light of this approach, the CSM’s decision appears ultimately in conflict with the constitutional purpose
of the Counsel itself, which is to safeguard and guarantee the general interest in relation to the judicial
power rather than to represent and manage the interests of the judicial officers
