REDO RSVP: Efficient Signalling for Multimedia in the Internet

Alarming reports of performance and scalability problems associated with per-flow reservations, have led many to lose belief in RSVP and the Integrated Services Architecture that relies on it. Because we are convinced of the need for some form of resource reservation, to support multimedia communications in the Internet, we have set about trying to improve RSVP. By careful study of the protocol, we have identified areas for improvement, and propose REDO RSVP, a reduced overhead version that includes a fast establishment mechanism (FEM). In this paper we describe the rationale for REDO RSVP and present a detailed analysis of its features and operations. We also analyse REDO RSVP by means of simulations, and show that it offers improvements to the performance of RSVP

Catheter ablation of atrial fibrillation : radiofrequency catheter ablation for redo procedures after cryoablation

Aim: To evaluate the effectiveness of two different strategies using radiofrequency catheter ablation for redo procedures after cryoablation of atrial fibrillation. Methods: Thirty patients (paroxysmal atrial fibrillation: 22 patients, persistent atrial fibrillation: 8 patients) had to undergo a redo procedure after initially successful circumferential pulmonary vein (PV) isolation with the cryoballoon technique (Arctic Front Balloon, CryoCath Technologies/Medtronic). The redo ablation procedures were performed using a segmental approach or a circumferential ablation strategy (CARTO; Biosense Webster) depending on the intra-procedural findings. After discharge, patients were scheduled for repeated visits at the arrhythmia clinic. A 7-day Holter monitoring was performed at 3, 12 and 24 mo after the ablation procedure. Results: During the redo procedure, a mean number of 2.9 re-conducting pulmonary veins (SD ± 1.0 PVs) were detected (using a circular mapping catheter). In 20 patients, a segmental approach was sufficient to eliminate the residual pulmonary vein conduction because there were only a few recovered pulmonary vein fibres. In the remaining 10 patients, a circumferential ablation strategy was used because of a complete recovery of the PV-LA conduction. All recovered pulmonary veins could be isolated successfully again. At 2-year follow-up, 73.3% of all patients were free from an arrhythmia recurrence (22/30). There were no major complications. Conclusion: In patients with an initial circumferential pulmonary vein isolation using the cryoballoon technique, a repeat ablation procedure can be performed safely and effectively using radiofrequency catheter ablation

The importance of prudential regulations in the process of transmitting monetary policy to economy

The main aim of prudential regulations is to increase the stability of financial systems; however, such regulations also increase the risk-taking tendency of banks, they encourage them to combine and limit their lending possibilities with, at the same time, lowering the efficiency of monetary policy in affecting economic processes. Thus, it occurs as a reasonable solution to integrate macroprudential supervision with monetary policy of the central bank and to subsequently limit the pro-cycle character of these regulations. The aim of this article is to discuss the importance of the regulatory channel in the process of transmitting impulses of monetary policy into economy and to overview the results of research, which analyzed the influence of macroprudential regulations on bank lending policy as well as their sensitivity towards monetary policy of the central bank

IDENTIFIKASI HAMBATAN BELAJAR SISWA PADA KONSEP PERSAMAAN KUADRAT

This research aims to identify learning obstacles and factors that cause learning obstacles experienced by students in learning the concept of quadratic equations. This research used a qualitative approach with the triangulation method, the subjects in this study were 23 class X students who had studied the concept of quadratic equations. The data collection technique in this research was to give a test in the form of a description question consisting of 2 questions to 23 students. Furthermore,  the researchers analyzed each student's answer and then interviewed 3 students who are considered to be able to represent other students in this research to look more deeply into the learning obstacles that students have on the concept of quadratic equations As well as conducting tests and interviews, the researchers made observations when students passed tests. The learning obstacles that the researcher found in the concept of quadratic equation were categorized into ontogenic obstacle, didactic obstacle, and epistemology obstacle. As a final result, the researchers realized: 1) students did not (fully) understand what a quadratic equation meant; 2) students met challenging to represent the problem in algebraic form; 3) students were able to overcome quadratic equations (test) in single way

UNITED NATIONS RULE OF LAW, “COMMON LANGUAGE OF JUSTICE” AND THE POST-2015 EDUCATIONAL AGENDA: SOME ACADEMIC AND POLICY ASPECTS

This interdisciplinary article first discusses some theoretical precepts of language and logic, then contextualizes them for the application of the United Nations (UN) Rule of Law. Next it argues that, while the international English language used in the Organization reflects specific national legal reasonings, the UN, by its nature, should harmonize Western and Eastern ways of thinking as they both contribute to the UN multivalent logic pursued for progressive ends. In conclusion, the article emphasizes that, notwithstanding the rather limited UN capacity for directly responding to educational justice needs across the world, UN rule-of-law evidence-driven recommendations and policies should have a more effective impact on justice education at all levels in the post-2015 UN Rule of Law agenda than they currently do.

A multi-user selective undo/redo approach for collaborative CAD systems

AbstractThe engineering design process is a creative process, and the designers must repeatedly apply Undo/Redo operations to modify CAD models to explore new solutions. Undo/Redo has become one of most important functions in interactive graphics and CAD systems. Undo/Redo in a collaborative CAD system is also very helpful for collaborative awareness among a group of cooperative designers to eliminate misunderstanding and to recover from design error. However, Undo/Redo in a collaborative CAD system is much more complicated. This is because a single erroneous operation is propagated to other remote sites, and operations are interleaved at different sites. This paper presents a multi-user selective Undo/Redo approach in full distributed collaborative CAD systems. We use site ID and State Vectors to locate the Undo/Redo target at each site. By analyzing the composition of the complex CAD model, a tree-like structure called Feature Combination Hierarchy is presented to describe the decomposition of a CAD model. Based on this structure, the dependency relationship among features is clarified. B-Rep re-evaluation is simplified with the assistance of the Feature Combination Hierarchy. It can be proven that the proposed Undo/Redo approach satisfies the intention preservation and consistency maintenance correctness criteria for collaborative systems

Results of redo pulmonary metastasectomy

: Repeat surgical resection (redo) for pulmonary metastases is a questionable, albeit intriguing topic. We performed an extensive review of the literature, to specifically analyze results of redo pulmonary metastasectomies. We reviewed a total of 3,523 papers. Among these, 2,019 were excluded for redundancy and 1,105 because they were not completely retrievable. Out of 399 eligible papers, 183 had missing information or missing abstract, while 96 lacked data on survival. A total of 120 papers dated from 1991 onwards were finally included. Data regarding mortality, major morbidity, prognostic factors and long-term survivals of the first redo pulmonary metastasectomies were retrieved and analyzed. Homogeneity of data was affected by the lack of guidelines for redo pulmonary metastasectomy and the risks of bias when comparing different studies has to be considered. According to the histology sub-types, redo metastasectomies papers were grouped as: colorectal (n=42), sarcomas (n=36), others (n=20) and all histologies (n=22); the total number of patients was 3,015. Data about chemotherapy were reported in half of the papers, whereas targeted or immunotherapy in 9. None of these associated therapies, except chemotherapy in two records, did significantly modify outcomes. Disease-free interval before the redo procedure was the prevailing prognostic factor and nearly all papers showed a significant correlation between patients' comorbidities and prognosis. No perioperative mortality was reported, while perioperative major morbidity was overall quite low. Where available, overall survival after the first redo metastasectomy ranged from 10 to 72 months, with a 5-years survival of approximately 50%. The site of first recurrence after the redo procedure was mainly lung. Despite the data retrievable from literature are heterogeneous and confounding, we can state that redo lung metastasectomy is worthwhile when the lesions are resectable and the perioperative risk is low. At present, there are no "non-surgical" therapeutic options to replace redo pulmonary metastasectomies
