Quantum interference and evolution of entanglement in a system of three-level atoms

We consider a pair of three-level atoms interacting with the vacuum. The process of disentanglement due to spontaneous emission and the role of quantum interference between principal transitions in this process, are analysed. We show that the presence of interference can slow down disentanglement. In the limit of maximal interference, some part of initial entanglement can survive.Comment: 6 pages, 8 figure

Telehealth Support Services for Students in Maine Schools Before and After the COVID Pandemic

The study also sought to learn what works well with telehealth delivery of therapy services for students with Individualized Education Plans IEPs and the drawbacks to using school-based telehealth services, from participants’ perspectives

How Students with IEP\u27s and their Teachers are Faring in Maine Schools during the COVID-19 Pandemic

The goal of study was to better understand how instruction to students with Individualized Education Plans (IEPs) was delivered during remote learning this past spring and during the fall semester of the 2020-21 school year, and how these vulnerable students have been impacted

Vacuum - induced stationary entanglement in radiatively coupled three - level atoms

We consider a pair of three - level atoms interacting with a common vacuum and analyze the process of entanglement production due to spontaneous emission. We show that in the case of closely separated atoms, collective damping can generate robust entanglement of the asymptotic states.Comment: published versio

Students as producers and active partners in enhancing equality and diversity: ‘culturosity’ at Canterbury Christ Church University

Equality and diversity of truths, of opportunity, of outcome, of dignity and of identities lie at the heart of the idea of university (Wolff, 1992, p. 68). However, despite the fact that the UK ‘has well-established equality law and practice’ and the Equality Act 2010 requires universities to implement changes that protect their students and employees from various forms and effects of discrimination, ‘inequality remains, albeit often in more complex and subtle forms than have been understood before’, argues David Ruebain (2012, p. 3). This study contributes to the discussion about equality and diversity practices in the university context by proposing strategies to embed into students’ learning community equality and diversity and subsequent graduate attributes. The case study is the Culturosity Project: an equality and diversity training initiative co-created by Dr Kasia Lech and a group of final-year students and graduates from Drama and Performing Arts programmes and delivered – as a Canterbury Christ Church University Partners in Learning project – to L4 and foundation-year students. The project was first delivered in 2015 and has now become part of student induction at the CCCU Faculty of Arts and Humanities

Challenges with Teacher Retention and Staffing and Shortages in Maine School Districts

The purpose of this study is to learn more about the challenges rural school districts in Maine face in hiring and retaining teachers, and the consequences or impacts of staffing shortages or under-qualified staff in certain areas

Birds through a ceiling of alabast : genderproblematiek in de romans van Hugo Claus

In the novels of Hugo Claus in which an "impossible love" is an important issue, we find, almost without exception, characters having characteristics that are typical for members of the opposite sex. (Latent) homosexuality plays an important role. The androgyny theme is the main theme in most of Claus' novels. There are two sources to be designated for this theme. In the first place, that is Freud, the founder of psychoanalysis. The other source is the ancient belief that man is an androgynous being, originally. The androgynous man or woman, the human beings in which the contrast between male and female characteristics are disappeared, are often to be associated with a heavenly state of being.UBL - phd migration 201

Cheapest-to-Deliver Collateral: A Common Factor Approach

The collateral choice option gives the collateral posting party the opportunity to switch between different collateral currencies which is well-known to impact the asset price. Quantification of the option's value is of practical importance but remains challenging under the assumption of stochastic rates, as it is determined by an intractable distribution which requires involved approximations. Indeed, many practitioners still rely on deterministic spreads between the rates for valuation. We develop a scalable and stable stochastic model of the collateral spreads under the assumption of conditional independence. This allows for a common factor approximation which admits analytical results from which further estimators are obtained. We show that in modelling the spreads between collateral rates, a second order model yields accurate results for the value of the collateral choice option. The model remains precise for a wide range of model parameters and is numerically efficient even for a large number of collateral currencies.Comment: 23 pages, 4 figures, 4 table

Space station common module network topology and hardware development

Conceptual space station common module power management and distribution (SSM/PMAD) network layouts and detailed network evaluations were developed. Individual pieces of hardware to be developed for the SSM/PMAD test bed were identified. A technology assessment was developed to identify pieces of equipment requiring development effort. Equipment lists were developed from the previously selected network schematics. Additionally, functional requirements for the network equipment as well as other requirements which affected the suitability of specific items for use on the Space Station Program were identified. Assembly requirements were derived based on the SSM/PMAD developed requirements and on the selected SSM/PMAD network concepts. Basic requirements and simplified design block diagrams are included. DC remote power controllers were successfully integrated into the DC Marshall Space Flight Center breadboard. Two DC remote power controller (RPC) boards experienced mechanical failure of UES 706 stud-mounted diodes during mechanical installation of the boards into the system. These broken diodes caused input to output shorting of the RPC's. The UES 706 diodes were replaced on these RPC's which eliminated the problem. The DC RPC's as existing in the present breadboard configuration do not provide ground fault protection because the RPC was designed to only switch the hot side current. If ground fault protection were to be implemented, it would be necessary to design the system so the RPC switched both the hot and the return sides of power
