Robust Entanglement in Atomic Systems via Lambda-Type Processes

It is shown that the system of two three-level atoms in $\Lambda$ configuration in a cavity can evolve to a long-lived maximum entangled state if the Stokes photons vanish from the cavity by means of either leakage or damping. The difference in evolution picture corresponding to the general model and effective model with two-photon process in two-level system is discussed.Comment: 10 pages, 3 figure

A framework for assessing clinical trial site readiness

Clinical trial processes are unnecessarily inefficient and costly, slowing the translation of medical discoveries into treatments for people living with disease. To reduce redundancies and inefficiencies, a group of clinical trial experts developed a framework for clinical trial site readiness based on existing trial site qualifications from sponsors. The site readiness practices are encompassed within six domains: research team, infrastructure, study management, data collection and management, quality oversight, and ethics and safety. Implementation of this framework for clinical trial sites would reduce inefficiencies in trial conduct and help prepare new sites to enter the clinical trials enterprise, with the potential to improve the reach of clinical trials to underserved communities. Moreover, the framework holds benefits for trial sponsors, contract research organizations, trade associations, trial participants, and the public. For novice sites considering future trials, we provide a framework for site preparation and the engagement of stakeholders. For experienced sites, the framework can be used to assess current practices and inform and engage sponsors, staff, and participants. Details in the supplementary materials provide easy access to key regulatory documents and resources. Invited perspective articles provide greater depth from a systems, DEIA (diversity, equity, inclusion, and accessibility) and decentralized trials perspective

Is the European Commission a 'Hothouse' for Supranationalism? Exploring Actor-Level Supranationalism

The article explores actor-level supranationalism among seconded national experts (SNEs) in the European Commission. The transformative clout of the European Commission is assessed by the extent to which SNEs adopt a "supranational" role perception. The survey and interview data presented demonstrates that SNEs evoke multiple roles, notably departmental, epistemic and supranational roles. OLS regression analyses reveal that actor-level supranationalism among SNEs reflect (i) processes of re-socialization inside the Commission, (ii) the organizational composition of the Commission and (iii) organizational "in"compatibilities between the Commission and domestic government institutions.
