Commercial aircraft family development has become one of the most important features of modern aircraft design. This paper explores the effects of commonality on different aircraft models in a commercial aircraft family. The existing product commonality indexes are summarized and their limitations in the application to aircraft design are discussed. Then a new component commonality index is proposed based on the component decomposition structure. A model for calculating the aircraft program value is established,which considers development costs, manufacturing costs, sale price, operation costs and residual costs. The effects of aircraft commonality on time and economic costs of both development and manufacturing, and on sale price, are analyzed and quantified. The commonality evaluation strategy is obtained, which features comprehensive consideration of the aircraft program value and time costs. The break-even analysis of aircraft is proceeded on the basis of costs and price data. By using a real option method, the strategy considers the uncertainty of the aircraft program and the flexibility of the manufacturer. This strategy proves to be rational and applicable to aircraft design based on the calculation of three examples and the analysis of parameter sensitivity.展开更多

Coming from the normal world that is ours, a small group of people is totally embarrassed and confused by observing this strange world. On the planet of the apes that they have discovered, it is the apes that are more intelligent than the humans. On the earth, it was the other way around. That observation results in their perplexity. The two communities, human and simian, bear with one another the relationship that corresponds to what Lotman calls ＂enantiomorphic pairings＂. In this context, a series of questions deserves to be raised： Is a ＂common language＂ possible between the two communities in the enantiomorphic pairings？ If the answer is yes, under what conditions could they succeed in opening up a space where they can have something in common？ In rereading The Planet of the Apes with reference to Lotman＇s semiotics of culture, we would like to formulate a response to those questions. Our claim is that the experience of finitude of one＇s own language can make possible an access to the new form of universality requisite for the cross-cultural communication： commonality without common points.展开更多

How...The common design of serial civil aircraft, an important strategy of modern civil aircraft research and develop-ment, minimizes the whole life cycle cost of civil aircraft through asset reuse and resource sharing. However, the existing estimating model for the R&D cost of civil aircraft ignores the effects of common design, so the value estimated by estimating derivative models is significantly inconsistent with the actual one. To solve this problem, a novel assessment method for civil aircraft commonality indicators is developed based on fuzzy set in the present study, exploiting the attributes and structural parameters of the aircraft to be assessed as input to determine the degree of membership that pertains to the commonality sub-interval as the commonality indicator.Then the BP(Back Propagation) neural network algorithm is adopted to establish the relationship between the common index and the decrease rate of the R&D cost of derivative models. The model employs over a dozen typical civil aircraft models(e.g., Boeing, Airbus, and Bombardier) as the sample data for network learning training to build a mature neural network model for estimating the R&D cost of novel derivative models. As revealed from the comparative analysis on the calculated results of the samples, the estimated results of the model given the effects of commonality in the present study exhibit higher estimation accuracy and value for future work.展开更多

To fully realize its potential benefits, one needs a clear understanding of its impacts on the system. In this paper, the feasibility of using a simulation model to provide a systematic perspective for manufacturing firms to implement a commonality strategy is demonstrated. Alternative commonality strategies including the stage of employing commonality and the allocation policies are simulated. Several interesting results on effects of commonality, allocation policies, and optimal solutions are obtained. We then summarize qualitative insights and managerial implications into the component commonality design and implementation, and inventory management in a general multi-stage assembly system.展开更多

There is a great need for a prophylactic treatment for colds. Specific antiviral treatments are only effective against one group of viruses and there is a need for a non-specific treatment that can be used against all respiratory viruses. Carrageenan is a general term used to describe a range of sulfated polysaccharides extracted from edible seaweeds. Large polyanionic molecules such as carrageenan have been shown to have antiviral activity against a wide range of viruses in vitro. The strong anionic charge of carrageenan attracts and traps viruses that have positively charged areas on their surface. The trapped viruses are then unable to infect epithelial cells. Iota-carrageenan exerts its’ antiviral activity by physical means due to its high anionic charge and it does not have any pharmacological properties and therefore does not have any toxicology or known side effects from treatment. Iota-carrageenan does not have any taste or smell and, when used as a nasal spray, does not have any adverse effects. Iota-carrageenan is an ideal prophylactic treatment for the common cold and is safe for use in children. Treatment of common cold with iota-carrageenan has to date been studied in five placebo-controlled clinical trials and these trials support both efficacy as a prophylactic treatment for colds and the safety and tolerability of iota-carrageenan.展开更多

文摘Commercial aircraft family design can reduce development costs, shorten development cycles, and expand the market coverage of aircraft. Commercial aircraft family development has become one of the most important features of modern aircraft design. This paper explores the effects of commonality on different aircraft models in a commercial aircraft family. The existing product commonality indexes are summarized and their limitations in the application to aircraft design are discussed. Then a new component commonality index is proposed based on the component decomposition structure. A model for calculating the aircraft program value is established,which considers development costs, manufacturing costs, sale price, operation costs and residual costs. The effects of aircraft commonality on time and economic costs of both development and manufacturing, and on sale price, are analyzed and quantified. The commonality evaluation strategy is obtained, which features comprehensive consideration of the aircraft program value and time costs. The break-even analysis of aircraft is proceeded on the basis of costs and price data. By using a real option method, the strategy considers the uncertainty of the aircraft program and the flexibility of the manufacturer. This strategy proves to be rational and applicable to aircraft design based on the calculation of three examples and the analysis of parameter sensitivity.

文摘The common design of serial civil aircraft, an important strategy of modern civil aircraft research and develop-ment, minimizes the whole life cycle cost of civil aircraft through asset reuse and resource sharing. However, the existing estimating model for the R&D cost of civil aircraft ignores the effects of common design, so the value estimated by estimating derivative models is significantly inconsistent with the actual one. To solve this problem, a novel assessment method for civil aircraft commonality indicators is developed based on fuzzy set in the present study, exploiting the attributes and structural parameters of the aircraft to be assessed as input to determine the degree of membership that pertains to the commonality sub-interval as the commonality indicator.Then the BP(Back Propagation) neural network algorithm is adopted to establish the relationship between the common index and the decrease rate of the R&D cost of derivative models. The model employs over a dozen typical civil aircraft models(e.g., Boeing, Airbus, and Bombardier) as the sample data for network learning training to build a mature neural network model for estimating the R&D cost of novel derivative models. As revealed from the comparative analysis on the calculated results of the samples, the estimated results of the model given the effects of commonality in the present study exhibit higher estimation accuracy and value for future work.
文摘The recent rapid development in information systems(ISs)has resulted in a critical need for integration and interoperability between heterogeneous ISs in various domains,using specific commonalities.However,stovepipe systems have been caused due to inconsistencies in planning IS architecture among stakeholders.So far,there has been no research on an enterprise architecture framework(EAF)that can satisfy with the coefficient factors of system architecture(SA)and enterprise architecture(EA).This paper proposes a new EAF that can resolve the problems inherent in existing legacy EAFs and their features.EAFoC(Enterprise Architecture Framework based on Commonality)is based on commonality that can be satisfied as the coefficient factors in both SA and EA within a common information technology(IT)domain.Thus,it should be possible to integrate an established heterogeneous framework for each stakeholder's view.Consequently,the most important contribution of this paper is to establish the appropriate EAFoC for the development of consistent IS architecture,smooth communication among stakeholders,systematic integration management of diversified and complicated new IT technologies,interoperability among heterogeneous ISs,and reusability based on commonality with other platforms.

Iota-carrageenan does not have any taste or smell and, when used as a nasal spray, does not have any adverse effects. Iota-carrageenan is an ideal prophylactic treatment for the common cold and is safe for use in children. Treatment of common cold with iota-carrageenan has to date been studied in five placebo-controlled clinical trials and these trials support both efficacy as a prophylactic treatment for colds and the safety and tolerability of iota-carrageenan.
文摘Ulcerative colitis has baffled researchers since the early 20th century.The pre-vailing explanation attributes the chronic recurring episodes of bloody diarrhea and abdominal pain to some form of immune abnormality,despite the lack of supporting evidence.This highlights the critical need for innovative research directions and methodologies to uncover the cause and develop a cure for this disease.By analyzing existing data from less than a dozen previously published studies,a novel,evidence-based pathogenesis was constructed,implicating colonic epithelial hydrogen peroxide as a causal factor in the development of this disease.This newly identified mechanism informed the creation of a ground-breaking class of therapeutics,known as reducing agents,which have demon-strated remarkable success in resolving colonic inflammation and restoring colonic health in patients with refractory ulcerative colitis.This paper outlines the timeline of these publications and reinterprets the findings within the context of contemporary biomedical science.

文摘Reconfigurable intelligent surface(RIS)is a novel meta-material which can form a smart radio environment by dynamically altering reflection directions of the impinging electromagnetic waves.In the prior literature,the inter-RIS links which also contribute to the performance of the whole system are usually neglected when multiple RISs are deployed.In this paper we investigate a general double-RIS assisted multiple-input multiple-output(MIMO)wireless communication system under spatially correlated non line-of-sight propagation channels,where the cooperation of the double RISs is also considered.The design objective is to maximize the achievable ergodic rate based on full statistical channel state information(CSI).Specifically,we firstly present a closedform asymptotic expression for the achievable ergodic rate by utilizing replica method from statistical physics.Then a full statistical CSI-enabled optimal design is proposed which avoids high pilot training overhead compared to instantaneous CSI-enabled design.To further reduce the signal processing overhead and lower the complexity for practical realization,a common-phase scheme is proposed to design the double RISs.Simulation results show that the derived asymptotic ergodic rate is quite accurate even for small-sized antenna arrays.And the proposed optimization algorithm can achieve substantial gain at the expense of a low overhead and complexity.Furthermore,the cooperative double-RIS assisted MIMO framework is proven to achieve superior ergodic rate performance and high communication reliability under harsh propagation environment.
文摘BACKGROUND Pancreaticobiliary maljunction(PBM)is a rare congenital abnormality in pancreaticobiliary duct development.PBM is commonly found in children,and it often leads to acute pancreatitis and other diseases as a result of pancreaticobiliary reflux.Roux-en-Y choledochojejunostomy is a common surgical method for the treatment of PBM,but there are several associated complications that may occur after this operation.CASE SUMMARY The patient,a 12-year-old female,was hospitalized nearly 20 times in 2021 for recurrent acute pancreatitis.In 2022,she was diagnosed with PBM and underwent laparoscopic common bile duct resection and Roux-en-Y choledochojejunostomy in a tertiary hospital.In the first year after surgery,the patient had more than 10 recurrent acute pancreatitis episodes.After undergoing abdominal computed tomography and other examinations,she was diagnosed with“residual bile duct stones and recurrent acute pancreatitis”.On January 30,2024,the patient was admitted to our hospital due to recurrent upper abdominal pain and was cured through endoscopic retrograde cholangiopancreatography.CONCLUSION This article reports a case of a child with distal residual common bile duct stones and recurrent acute pancreatitis after Roux-en-Y choledochojejunostomy for PBM.The patient was cured through endoscopic retrograde cholangiopancreatography.
文摘BACKGROUND Common bile duct stones pose a high risk of recurrence or disease progression if not promptly treated.However,there is still no optimal treatment approach.AIM To investigate the clinical efficacy of modified pancreatic duct stent drainage in endoscopic retrograde cholangiopancreatography(ERCP)for treating common bile duct stones.METHODS This retrospective study included 175 patients with common bile duct stones treated at Taizhou Fourth People’s Hospital between January 1,2021,and November 30,2023.The patients were divided into three groups-the modified pancreatic duct stent drainage group(59 cases),the nasobiliary drainage group(58 cases),and the standard biliary drainage group(58 cases).Preoperative general clinical data,laboratory indicators,and the visual analog scale(VAS)at two time points(24 hours before and after surgery)were compared,along with postoperative complications across the three groups.RESULTS Serum levels of aspartate aminotransferase,alanine aminotransferase,alkaline phosphatase,gamma-glutamyltransferase,total bilirubin,direct bilirubin,Creactive protein,and amylase were significantly lower in the modified pancreatic duct stent drainage group and the standard biliary drainage group than those in the nasobiliary drainage group(P<0.05).However,no statistically significant differences were observed in white blood cells,hemoglobin,or neutrophil levels among the three groups(P>0.05).The standard biliary drainage group had significantly lower VAS scores[(4.36±1.18)points]than those for the modified pancreatic duct stent drainage group[(4.92±1.68)points](P=0.033),and the nasobiliary drainage group[(5.54±1.24)points](P=0.017).There were no statistically significant differences in complication rates across the three groups(P>0.05).CONCLUSION Compared to standard biliary drainage and nasobiliary drainage,the modified pancreatic duct stent used during ERCP for patients with bile duct stones significantly reduced hepatocyte injury,improved liver function parameters,alleviated inflammation and pain,enhanced patient comfort,and demonstrated superior safety.
