Quantum Inequalities and Singular Energy Densities

, 1997
There has been much recent work on quantum inequalities to constrain negative energy. These are uncertainty principle-type restrictions on the magnitude and duration of negative energy densities or fluxes.

Optimised Search Heuristic Combining Valid Inequalities and Tabu Search [PDF]

SSRN Electronic Journal, 2008
This paper presents an Optimised Search Heuristic that combines a tabu search method with the verification of violated valid inequalities. The solution delivered by the tabu search is partially destroyed by a randomised greedy procedure, and then the valid inequalities are used to guide the reconstruction of a complete solution.

“And in some cases, we're the best option:” A qualitative study of community‐based doula support for black perinatal mental health

American Journal of Community Psychology, EarlyView.
Abstract We explored community‐based doulas' perspectives on the acceptability of using formal screening tools to address low rates of mental health screening, diagnosis, and treatment for perinatal anxiety and depression among Black women. Using thematic analysis, we analyzed interview data from 30 community‐based doulas who support Black families ...

Commutators in real interpolation with quasi-power parameters

Abstract and Applied Analysis, 2002
The basic higher order commutator theorem is formulated for the real interpolation methods associated with the quasi-power parameters, that is, the function spaces on which Hardy inequalities are valid.

Maximin is Not Enough

, 2017
The RT formula for static spacetimes arising in the AdS/CFT correspondence satisfies inequalities that are not yet proven in the case of the HRT formula, which applies to general dynamical spacetimes.

Participation for mental health service development in China: Conditions, challenges, facilitators, and outcomes

American Journal of Community Psychology, EarlyView.
Abstract This study analyzes a participatory project to develop peer support services for people with serious mental illnesses (SMIs) in China. Drawing on interviews with psychiatrists, social workers, service users, and a family caregiver, it examines the conditions, challenges, facilitators, and outcomes of participation in a paternalistic context ...

Entropic inequalities as a necessary and sufficient condition to noncontextuality and locality

, 2013
The assumption of local realism in a Bell locality scenario imposes non-trivial conditions on the Shannon entropies of the associated probability distributions, expressed by linear entropic Bell inequalities.

Neighborhood social environments and mental health among youth and adults in public housing

American Journal of Community Psychology, EarlyView.
Abstract Neighborhoods influence health in part through social processes. However, little is known about how multiple neighborhood social processes co‐occur, or about within (vs. between) neighborhood variation in social processes and health. This study asked how residents of a large public housing development describe their neighborhood and used ...

Influence optimization in networks: New formulations and valid inequalities

Computers & Operations Research
Influence propagation has been the subject of extensive study due to its important role in social networks, epidemiology, and many other areas. Understanding propagation mechanisms is critical to control the spread of fake news or epidemics. In this work, we study the problem of detecting the smallest group of users whose conversion achieves, through ...
