advancing transcatheter mitral valve repair

the mitral butterfly implant is a posterior leaflet augmentation device which functions to prevent excessive posterior leaflet motion the implant comprises aa nitinol frame designed to sit comfortably within the anatomy of the heart and to provide the overall structure of the implantban artificial leaflet in the form of a flexible mesh which serves to restrict the prolapsing leaflet and provide a surface for adequate coaptation and ca method of anchoring the implant can be folded into a catheter to facilitate delivery and be deployed in the target region with minimal actuation the shape memory capabilities of nitinol allow the implant to selfexpand when released and the design of the frame ensures the correct orientation within the valve consequently the procedure involves minimal actuated steps with the main mechanical complexity arising from the anchorage the anchorage itself is achieved with a secondary selfexpanding nitinol mechanism
reviving the ascetic ideal in the eastern mediterranean entangled memories of early egyptian monasticism in medieval syriac arabic and armenian christianity 9691375 ce

revidem combines new insights from cultural memory studies mediterranean intellectual history and manuscript studies in order to provide the first comprehensive analysis of the monastic revival in the eastern mediterranean between 969 and 1375 ce challenging traditional avenues of research revidem will focus on the metanarratives myths about the origins of christian monasticism in egypt 4th century ce and their later reception in the culturally complex environment of the medieval mediterranean the project reappraises this ample medieval engagement with late antique asceticism as an original intellectual endeavour spanning linguistic and political boundaries to the same end revidem will tap the enormous potential of the large number of syriac arabic and armenian ascetic manuscripts produced in this time frame as new sources for the religious cultural and social history of the region essential information on the scribes readers users and circulation of these documents will be collected in an online database by interpreting this hitherto neglected corpus of sources as focal points of cultural memory making revidem will explain the lasting success and wideranging impact of the egyptian ascetic ideal in the medieval mediterranean the project will thus pinpoint the role of cultural memory as the main catalyst of the monastic revival in order to achieve these objectives the team will focus on carefully selected case studies from northern syria egypt and armenian cilicia exploring the ways in which the monastic authors scribes and compilers of these regions constructed and disseminated their narratives of early desert asceticism by revaluing the cultural social and political significance of monastic life in the medieval levant and highlighting the role of metanarratives and cultural memory as engines of historical change the results of revidem will represent a major paradigm shift in the study of mediterranean history

models assessment and policies for sustainability

maps aims to broaden the range of policies models and assessments to help achieve sustainability equity and human wellbeingthe lack of evidence for sufficient absolute decoupling between economic growth and environmental pressures suggests that future trajectories built on economic growth may not be possible there is an urgent need for a new paradigm that reconciles human wellbeing with environmental sustainability one based on a postgrowth approach the idea is that highincome countries should move beyond the pursuit of gdp growth as a policy goal and instead pursue policies that improve human wellbeing while reducing resource usedespite increasing interest in this idea the main integrated assessment models iams used in climate mitigation modelling do not consider postgrowth policies or scenarios maps has the ambition to expand the range of policy options available to policymakers and incorporate postgrowth scenarios into the major scientific assessments of the ipcc and ipbes our goal is to provide new approaches to help steer europe and the world back within planetary boundaries without compromising on valuable social welfare goalsto this end maps will use participatory processes to develop new policy packages and scenarios and then assess these policies using a stateoftheart simulation model in particular it will estimate the resource use requirements of a good life design social welfare systems that are growthresilient incorporate a broader range of environmental and social indicators into assessment models and explore how alternative policies could be implemented in practicemaps will provide knowledge about policies that reduce resource use to be within planetary boundaries while maintaining or improving social outcomes in so doing it will improve decisionmaking capacity by broadening the range of policy options modelling frameworks and assessments for sustainability

algebraic formula lower bounds and applications

does efficient verification imply efficient search can randomness provide massive speedups in computation these are fundamental questions in theoretical computer science known as p vs np and p vs bpp respectively progress on these questions requires us to to show that certain computational problems are inherently intractable ie do not admit efficient solutions an important and concrete approach to such questions is to understand the complexity of algebraic problems such as the determinant and the permanent in algebraic models of computation the aim of this project is to tackle these questions head onrecent results of the pi and his collaborators have made progress on these problems by resolving a threedecade old open question these results show intractability for algebraic models of bounded depth which is a step towards p vs np as a consequence they also imply the first subexponential time deterministic algorithms for the important polynomial identity testing pit problem in these settings which is progress towards p vs bpphowever this barely scratches the surface of what we want to achieve the aim of this project is to push beyond these stateoftheart results in many directions the principal goal is to prove the first lower bounds for algebraic formulas which would be a huge breakthrough further we want to improve our recently obtained lower bounds in order to devise faster pit algorithms we also want to show lower bounds over finite fields and to explore the applications of such work in related areas such as algebraic proof complexity and algorithm design the recent results point out a new way of exploiting structural and algebraic techniques to prove lower bounds the aim is to develop and systematically investigate these techniques incorporating methods from related fields of mathematics such as the theory of symmetric functions and representation theory to accomplish these goals
productive signs a computerassisted analysis of evolutionary typological and cognitive dimensions of word families

all human languages have simple and complex words simple words refer to meanings regardless of their form while complex words are formed from other words and their formation can be semantically motivated since words can share lexical material we can group them into families word families can vary greatly in size ranging from small ones comprising only a few members to large ones spanning several hundred words but it is still unclear why some words are more productive than others in forming new words lexical compositionality has received some attention in historical linguistics linguistic typology and cognitive linguistics but so far studies have mostly concentrated on the morphological complexity of individual words and languages while the fact that words form families which interact during language change and language use has been typically ignored as a result many questions regarding word family formation remain unresolved and we do not know 1 how word families evolve along language phylogenies 2 which semantic processes underlying word family formation are universal and 3 to what extent human cognition influences the productivity of lexical roots to form families the project will tackle these three target questions by unifying evolutionary typological and cognitive insights into lexical compositionality building on a computerassisted framework that reconciles classical and computational approaches in historical linguistics and linguistic typology the project will design new models to standardize crosslinguistic data on word families apply them to integrate data from historical linguistics linguistic typology and cognitive linguistics and develop new methods for the computerassisted inference of word families their underlying motivation patterns and their evolutionary histories in large datasets in this way the project will deepen the integration of crosslinguistic studies in cognitive and psychological sciences
