A formally verified compiler back-end

This article describes the development and formal verification (proof of semantic preservation) of a compiler back-end from Cminor (a simple imperative intermediate language) to PowerPC assembly code, using the Coq proof assistant both for programming the compiler and for proving its correctness. Such a verified compiler is useful in the context of formal methods applied to the certification of critical software: the verification of the compiler guarantees that the safety properties proved on the source code hold for the executable compiled code as well

BUILDING BRIDGES FOR INNOVATION IN AGEING : SYNERGIES BETWEEN ACTION GROUPS OF THE EIP ON AHA

The Strategic Implementation Plan of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) proposed six Action Groups. After almost three years of activity, many achievements have been obtained through commitments or collaborative work of the Action Groups. However, they have often worked in silos and, consequently, synergies between Action Groups have been proposed to strengthen the triple win of the EIP on AHA. The paper presents the methodology and current status of the Task Force on EIP on AHA synergies. Synergies are in line with the Action Groups' new Renovated Action Plan (2016-2018) to ensure that their future objectives are coherent and fully connected. The outcomes and impact of synergies are using the Monitoring and Assessment Framework for the EIP on AHA (MAFEIP). Eight proposals for synergies have been approved by the Task Force: Five cross-cutting synergies which can be used for all current and future synergies as they consider overarching domains (appropriate polypharmacy, citizen empowerment, teaching and coaching on AHA, deployment of synergies to EU regions, Responsible Research and Innovation), and three cross-cutting synergies focussing on current Action Group activities (falls, frailty, integrated care and chronic respiratory diseases).Peer reviewe

Interpersonal relationships and adjustment of children in homeless and economically distressed families

Assessing the protective elements of social relationships for sixty 7- to 12-year-old children and their mothers residing in homeless shelters and 61 children and their mothers in low-income housing allowed us to test an ecological model of the impact of social relationships, income, stress, and maternal mental health on child adjustment for children in these two types of distressed families. Social relationships included the quality of the child\u27s relationships with parents, teachers, other relatives, andfriends. The model showed that for the homeless group, a lack of social support and maternal depression were significantly associated with adjustment dificulties in the child, whereas for the housed low-income group, environmental stress was associated with behavioral adjustment problems in the child. Perceptions of self-worth were associated with the presense of supportive relationships for children in both groups
