In this research, a novel "thermal capacity on demand" approach to modular thermal storage design has been discussed, seen as a key to the climatic adaptability of a proposed Smart-POD building system and its energy performance. Smart-POD is a unique and innovative research project which provides an alternative to traditional classroom design. It proposes a rapid deployment building solution, temporary or permanent in its use, modular in design, flexible in set-up and self-sustaining in use, requiring minimal site preparation, and meeting all its energy demands from renewable energy sources. Its feasibility was tested by a design case study which investigated climatic adaptability based on the proposed approach. This approach uniquely combines balancing of energy demand and supply using renewable technologies and a bespoke low temperature thermal store. It further proposes to use an open source Building energy Management System (oBeMS) conceived in this research, to intelligently manage thermal, ventilation and humidity control strategies which adapt to the climate, season and weather in which the building is placed. The predicted performance of proposed system demonstrates potential for an effective diurnal climatic adaptability, enhanced by integrated passive design strategies, and intelligent modes of building control. The method of BIM integrated sustainable design analysis (SDA) and building management system (BMS) has also been deliberated, as a framework for exploring the integration of proposed building management system into smart building environments (SBEs).

Background The ease of implantation of the rapid deployment (RD) and sutureless valves has contributed to the adoption of anterior right thoracotomy (ART) approach for aortic valve replacement (AVR). Aim of the study This study evaluates the safety and haemodynamic performance of minimally invasive AVR through ART using the RD valves. Methods This is a retrospective, single-center review of a total of 50 consecutive patients who received RD-AVR through ART. Results The median age of patients was 75 years (interquartile range [IQR]: 69-80), and median Euroscore II was 5.1 (IQR: 2.4-7.5). ART RD-AVR was successfully performed in all cases with no conversion to sternotomy, paravalvular leaks or need for valve explantation. The mean size of the implanted valve was 23.2 +/- 2.3 mm. In-hospital mortality was 2%. The mean and maximum pressure gradients across the aortic prosthesis were 10 mm Hg (IQR: 9-12) and 19 mm Hg (IQR: 16-23). Conclusions rapid deployment aortic valve replacement can be safely performed through anterior right thoracotomy wit excellent haemodynamic performance and low postoperative complications rate.

A best evidence topic was written according to a structured protocol. The question addressed was 'In patients requiring an aortic valve replacement, are rapid deployment aortic valve systems better than conventional aortic valve prostheses in terms of mortality, morbidity and/or valve function?' A total of 508 papers were found using the reported search, of which 11 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. The rapid deployment valves (RDVs) implanted in these studies include balloon expandable [Intuity (Edwards Lifesciences, CA, USA) and 3F Enable (Medtronic, MN, USA)] and self-expanding [Perceval (Sorin, Saluggia, Italy)] stented bioprostheses. Available data from these studies demonstrate that rapid deployment valves are invariably associated with shorter aortic cross-clamp times (30-56 vs 49-88 min). Despite this, postoperative mortality (0-5.8 vs 0-6%), ICU (1-3 vs 0.9-2.8 days) and hospital length of stay (6-14.1 vs 6-15.9 days) are similar compared with conventional aortic valve replacement (AVR). However, reduced postoperative bleeding (328 vs 564 ml), blood transfusion requirements (1.4 vs 2.4 units), ventilation time (4.9-9.5 vs 7-16.6 h) and renal injury (5.3 vs 14.7%) have been demonstrated with RDVs indicating possible clinical benefit to shorter procedural time. Importantly, patient risk profiles were similar to or higher across studies in patients undergoing RDVs compared with conventional AVR. From a functional perspective, transvalvular gradients were frequently lower with rapid deployment valves compared with conventional AVR, indicating an improved haemodynamic profile. However, in some studies using the Perceval RDV, the transvalvular gradients were higher than with conventional AVR. Also, mean valve sizes were often larger in those receiving RDVs.

Besides UCAV, present winged or helicopter-style UAVs waste too much time and fuel to takeoff and arrive an unpredicted trouble spot. This study presents two design concepts of rapid deployment UAV: the first is vertical launch surface-based rapid deployment UAV (RDUAV), and the second is Air-Launched rapid deployment UAV (AL-RDUAV). The proposed rapid deployment UAVs should rapidly reach the destination to eliminate the time gap and keep the original advantages of UAV. Both the RDUAV and AL-RDUAV are not only beneficial for military uses but also can perform rapid response to anti-terror missions or serious emergencies. ©2008 IEEE.

Introduction rapid deployment aortic valve replacement has been recently introduced in clinical practice. Different studies have reported a significant reduction in surgical times with excellent hemodynamic profiles and short-term results. However, an increase in permanent pacemaker requirements compared with conventional aortic valve replacement has been described. Nevertheless, risk factors for postoperative pacemaker implantation are not well known. The aim of this study is to report our early outcomes with rapid deployment aortic valve replacement within the RADAR Registry, especially focusing on risk factors for postoperative pacemaker implantation. Methods Between April 2012 and January 2016, 164 patients undergoing isolated or combined aortic valve replacement with Edwards INTUITY Elite (Edwards Lifesciences, Irvine, CA, USA) were included in the RADAR Registry. Pre-, intra- and postoperative clinical data results and complications were recorded, especially focusing on risk factors for the development of postoperative complete or high-grade AV block requiring pacemaker implantation. Patients were followed up for up to 1 year with evaluation of clinical and echocardiographic outcomes. Results A total of 164 consecutive patients were included in this study, where 128 patients (78.05%) had an isolated aortic valve replacement (group 1) and 36 (21.95%) a concomitant procedure (group 2). The surgical approach was ministernotomy in 61 patients (37.20%) and median sternotomy in 100 patients (60.98%). Complications with valve implantation were observed in three patients. Postoperative complete or high-degree AV block requiring a permanent pacemaker implantation developed in ten patients (6.9%). Seven patients died in-hospital (4.27%). No significant differences between groups were found in terms of stroke, postoperative infection, mortality, atrial fibrillation and postoperative atrioventricular block. Seven patients presented acute renal impairment (5.51%) in group

OBJECTIVES: Limited access aortic valve replacement is an alternative approach for the treatment of calcified aortic valve disease. To facilitate limited access aortic valve replacement, rapid deployment valve prostheses have been developed aiming to reduce surgical impact. This systematic review gives an overview of current literature regarding the INTUITY or INTUITY Elite rapid deployment biological valve prosthesis. Methods: Cochrane, Embase and MEDLINE were searched to identify relevant studies. All studies reporting on patients who underwent isolated or combined surgical aortic valve replacement with the INTUITY or INTUITY Elite valve prosthesis were considered eligible. Primary end points were technical success rate, 30-day mortality, cerebrovascular accident, paravalvular leak and permanent pacemaker implantation. Secondary end points included procedural data such as aortic cross-clamping time, cardiopulmonary bypass time and procedural approach. Results: A total of 16 articles fulfilled the inclusion and exclusion criteria and comprised 4.184 patients. Thirty-day mortality was 2.7% (1.9-3.7%), cerebrovascular accident 2.6% (1.4-4.7%), permanent pacemaker implantation 7.9% (6.6-9.5%) and severe postoperative paravalvular leak requiring a reintervention 3.3% (1.7-6.1%). Technical success rate varied between 93.9% and 100%. Conventional median sternotomy was most commonly performed, ranging from 21.7% to 89.6%. Upper hemi-sternotomy was performed more often than anterior right thoracotomy, ranging from 10.4% to 63.3% and 2.2% to 26.1%. The mean transvalvular pressure gradient ranged between 9.0 and 10.3mmHg at 1 year postoperatively. Conclusions: This review demonstrates that the technical success rate of the INTUITY or INTUITY Elite rapid deployment valve system is high, also in limited access aortic valve replacement. Mortality and cerebrovascular accident rates are low, but the need for postoperative permanent pacemaker implantation and reintervention rate f

Designed to address the challenges of a sustainable future and the financial difficulties facing schools, Smart-POD is a unique and innovative research project which provides an alternative to traditional classroom planning. It proposes a rapid deployment building solution, transitory or permanent in its use, modular in design, flexible in set-up and self-sustaining in use, requiring nominal site works and providing for all of its energy demands from renewable energy sources. Its feasibility was tested via a design case study which investigated potential of its novel "thermal capacity on demand" energy performance approach. It combines a modular thermal storage solution capable of balancing heating demand and supply for a low rise, low mass superstructure with renewable technologies and the level of backup power/services needed. The project team has folined a consortium of stakeholders and consulted on design methodology, performance specification and viability of other markets, the results of which are reported in this paper. The research has, in its final output, established a commercial model based on its design, procurement, financing, supply chain and the manufacturing strategy and is currently negotiating funding for the prototype.

Objective: The optimal approach and choice of initial aortic valve replacement (AVR) is evolving in the growing era of transcatheter AVR. Further survival and hemodynamic data are needed to compare the emerging role of rapid deployment (rdAVR) versus stented (sAVR) valve options for ***: The Northern New England Cardiovascular Database was queried for patients undergoing either isolated AVR or AVR + coronary artery bypass grafting (CABG) with rdAVR or sAVR aortic valves between 2015 and 2021. Exclusion criteria included endocarditis, mechanical valves, dissection, emergency case status, and prior sternotomy. This resulted in a cohort including 1,616 sAVR and 538 rdAVR cases. After propensity weighting, procedural characteristics, hemodynamic variables, and survival outcomes were examined. Results: The breakdown of the overall cohort (2,154) included 1,164 isolated AVR (222 rdAVR, 942 sAVR) and 990 AVR + CABG (316 rdAVR, 674 sAVR). After inverse propensity weighting, cohorts were well matched, notable only for more patients <50 years in the sAVR group (4.0% vs 1.9%, standardized mean difference [SMD] = -0.12). Cross-clamp (89 vs 64 min, SMD = -0.71) and cardiopulmonary bypass (121 vs 91 min, SMD = -0.68) times were considerably longer for sAVR versus rdAVR. Immediate postreplacement aortic gradient decreased with larger valve size but did not differ significantly between comparable sAVR and rdAVR valve sizes or overall (6.5 vs 6.7 mm Hg, SMD = 0.09). Implanted rdAVR tended to be larger with 51% either size L or XL versus 37.4% of sAVR >= 25 mm. Despite a temporal decrease in pacemaker rate within the rdAVR cohort, the overall pacemaker frequency was less in sAVR versus rdAVR (4.4% vs 7.4%, SMD = 0.12), and significantly higher rates were seen in size L (10.3% vs 3.7%, P < 0.002) and XL (15% vs 5.6%, P < 0.004) rdAVR versus sAVR. No significant difference in major adverse cardiac events (4.6% vs 4.6%, SMD = 0.01), 30-day survival (1.5% vs 2.6%, SMD = 0.08), or

This paper designs a kind of LED markers as well as the counterpart recognition algorithm for calibrating cameras in need for the rapid deployment for WMSN. Firstly, the implementation of WMSN calibration process is introduced. Afterwards, by analyzing the defects of algorithms using feature extraction for recognition, a simpler two-dimensional marker recognition method is designed. The recognition algorithm for the markers is described in detail. By experimenting in different circumstances we prove that our method is simple and fast, with good anti-interference and rotation invariance performance. Besides it provides essential and sufficient corner information for the following calibration process. Thus the presented LED marker and detection method is suitable for calibrating camera nodes in practical applications.

Slow Progress on UN rapid deployment: The Pitfalls of Policy Paradigms in International Organizations

INTERNATIONAL STUDIES REVIEW 2021年第3期23卷 455-483页

When reform negotiations in international organizations (IOs) produce limited substantive progress, the diagnosis is typically a lack of political will. We identify a different dynamic: in protracted negotiations, international policy paradigms can emerge that enshrine a politically realistic but incomplete issue definition and thereby focus the debate on a subset of policy instruments that do not fully address the underlying problem. We draw on the multilateral negotiations literature to show how policy paradigms-which are widely explored in Comparative Politics, but largely neglected in International Relations-can emerge even in heterogenous IOs, where deep cognitive cohesion is unlikely. The risk of negotiation failure incentivizes negotiators to adopt and maintain "achievable" issue and goal definitions, which over time are accepted as axiomatic by diplomats, IO officials, and policy experts. The resulting international policy paradigms help avoid institutional paralysis, but can also impede more ambitious reforms. To establish the empirical plausibility of this argument, we highlight the contemporary international policy paradigm of rapid deployment in UN peacekeeping, which focuses more on establishing an initial brigade-sized presence than on rapid deployment of the full peacekeeping force. Drawing on primary documents and interviews, we identify the roots of this First Brigade policy paradigm in reactions to the UN's failure to respond to the 1994 Rwandan genocide and trace its consolidation during UN reform negotiations in the 2000s and early 2010s. We also demonstrate that an alternative explanation of the paradigm as reflecting operational lessons-learned does not hold: a brigade-sized initial presence is rarely sufficient for mandate implementation, does not reliably speed up full deployment, and creates risks for peacekeepers. By highlighting the existence and impact of international policy paradigms, our study adds to scholarship on the role of ideas i
