C-Link: a hierarchical clustering approach to large-scale near-optimal coalition formation
No full textCoalition formation is a fundamental approach to multi-agent coordination. In this paper we address the specific problem of coalition structure generation, and focus on providing good-enough solutions using a novel heuristic approach that is based on data clustering methods. In particular, we propose a hierarchical agglomerative clustering approach (C-Link), which uses a similarity criterion between coalitions based on the gain that the system achieves if two coalitions merge. We empirically evaluate C-Link on a synthetic benchmark data-set as well as in collective energy purchasing settings. Our results show that the C-link approach performs very well against an optimal benchmark based on Mixed-Integer Programming, achieving solutions which are in the worst case about 80% of the optimal (in the synthetic data-set), and 98% of the optimal (in the energy data-set). Thus we show that C-Link can return solutions for problems involving thousands of agents within minutes
Long Duration Balloon flights development (Italian Space Agency)
No full textStratospheric balloons are rapidly becoming the vehicle of choice for near space investigations and earth observations by a variety of science disciplines. With the ever increasing research into climatic change, earth observations, near space research and commercial component testing, instruments suspended from stratospheric balloons offer the science team a unique, stable and reusable platform that can circle the Earth in the polar region or equatorial zone for thirty days or more. The Italian Space Agency (ASI) in collaboration with Andoya Rocket Range (Andenes, Norway) has opened access in the far northern latitudes above 78o N from Longyearbyen, Svalbard. In 2006 the first Italian UltraLite Long Duration Balloon was launched from Baia Terra Nova, Mario Zuchelli station in Antarctica and now ASI is setting up for the their first equatorial stratospheric launch from their satellite receiving station and rocket launch site in Malindi, Kenya. For the equatorial missions we have analysed the statistical properties of trajectories considering the biennial oscillation and the seasonal effects of the stratospheric winds. Maintaining these launch sites offer the science community 3 point world coverage for heavy lift balloons as well as the rapidly deployed Ultra-light payloads and TM systems ASI developed to use for test platforms, micro experiments, as well as a comprehensive student pilot program. This paper discusses the development of the launch facilities and international LDB development
Beta Beams for Neutrino Production
No full textTo use accelerated beta active ions to produce collimated high energy neutrino beams was proposed by P. Zuchelli in 2002 and studies of a suitable accelerator complex, based on CERN accelerators, have been supported by research programs within the European Commisison FP6 and FP7 frameworks (EURISOL Design Study and EUROnu). In these studies 6He and 18Ne are used as beta emitters to produce antineutrinos and neutrinos respectively. Alternative isotopes for neutrino beam production, giving higher neutrino energies, 8Li and 8B, are investigated in the now ongoing study, EUROnu. The isotopes for neutrino beams have to be produced in large quantities using non conventional methods. The work achieved gives a good ground to propose the Beta Beam, for neutrino production. Technical issues related to a Beta Beam facility using the CERN infrastructure are reviewed
Management of Gastro-Jejunal Anastomotic Strictures: Comparing Endoscopic Outcomes in Primary vs Conversion Roux-en-Y Gastric Bypass Patients
No full textIntroduction: Conversion surgery from sleeve gastrectomy (SG) to Roux-en-Y gastric bypass (RYGB) is a common intervention for GERD and weight recurrence. There is limited data on post-surgical gastrojejunal anastomotic strictures (GJAS) endoscopic therapy outcomes in patients with sleeve gastrectomy to Roux-en-Y gastric bypass (SG-RYGB) conversion surgeries. Our study aims to compare the outcomes of primary RYGB (P-RYGB) and SG-RYGB GJAS when treated with through-the-scope balloon dilation (TTS BD) and lumen-apposing metal stent (LAMS). Methods: This is a single center retrospective study, that included patients diagnosed with GJAS post P-RYGB and SG-RYGB surgeries who underwent TTS BD or intraluminal LAMS placement. Data was collected between 2/1/2013 - 1/1/2023. Primary outcomes were technical success, clinical success, surgical revision & mortality. Secondary outcomes included immediate clinical success and the number of endoscopic sessions needed to achieve clinical success. Results: A total of 22 patients were identified to have GJAS, 13 post P-RYGB (age 55 67) & 9 post SG-RYGB (age 45.5 66). Among the P-RYGB group, 4 patients were treated with TTS BD (median stricture diameter 5 mm) and 9 with LAMS (median stricture diameter 5.5 mm). Whereas within the 9 SG-RYGB patients, 7 received TTS BD (median stricture diameter 8.5 mm), and 2 underwent LAMS placement (median stricture diameter 7 mm). All 22 patients had a 100% technical success rate with no mortality or need for surgical revision. Half (n=2/4) of the P-RYGB patients had clinical success with TTS BD compared to 89% (n=8/9) of those who received LAMS. In SG-RYGB patients, almost half of those who received TTS BD (n=3/7) & LAMS stents (n=1/2) had immediate clinical success following first intervention. During the duration of the study, 4/7 (57%) TTS BD and 2/2 (100%) LAMS SG-RYGB patients maintained clinical success without symptom recurrence. One P-RYGB case experienced intraprocedural LAMS mis-deployment. Post-procedure adverse event rates were reported in 1 P-RYGB TTS BD patient & 3 P-RYGB LAMS patients (Table 1). Conclusion: This study demonstrates that both TTS BD and LAMS are effective in the management of GJAS following primary as well as conversion bariatric surgery. LAMS generally exhibited higher immediate and maintenance clinical success rates compared to TTS BD, especially in P-RYGB patients. Further multicenter research involving larger patient cohorts is warranted to optimize patient outcomes in this population. (Table Presented)
