Lower bound for the mean square distance between classical and quantum spin correlations

Bell's theorem prevents local Kolmogorov-simulations of the singlet state of two spin-1/2 particles. We derive a positive lower bound for the $L^{2}$-distance between the quantum mechanical spin singlet anticorrelation function $\cos$ and any of its classical approximants $C$ formed by the stationary autocorrelation functions of mean-square-continuous, $2\pi$-periodic, $\pm1$-valued, stochastic processes. This bound is given by $\Vert C-\cos\Vert \geq(1-\frac{8}{\pi^{2}}) /\sqrt{2}\approx0.133\,95.$Comment: 11 pages, no figure

CONVIS: A tool enabling uninterrupted operation during refurbishments of complex buildings

Clash Detection refers to the identification of geometrical overlaps within a Building Information Model (BIM). This paper seeks to extend the notion of overlapping to activities: Given a construction site within a building, we seek to find clashes between construction activities and occupant routines. Such a situation is often encountered in the context of refurbishments of complex buildings operating 24/7 (e.g. airports, train stations, hospitals, prisons). By finding the influence radii of adverse effects resulting from construction - i.e. dust, noise and vibrations, functions may be temporarily relocated in order to guarantee uninterrupted operation. Our tool CONVIS implements these simulation and scheduling aspects and seeks to provide a digital project plan for refurbishments in the said context

Noise Solver for Refurbishment Construction Site Design

The noise generated by the presence of a construction site within complex structure in operation (e.g. school, hospital) is a problem that too often is underestimated but that can generate problems of different nature, both concerning the health of the actors involved and regarding the performance of daily activities present within such structures (e.g. carrying out a lesson, a surgical procedure). The main aim of our tool is to highlight the impact of the noise generated by the construction site activities on these daily activities and to allow the simulation in real time of the viable solutions, thus arriving to find the one that is considered most suitable

Exploring Parent Adverse Childhood Event Influence on Offspring Weight and Development

Background: The purpose of this literature review is to explore the impact of parental adverse childhood events on weight and development in their offspring. This includes occurrences of offspring obesity, delays in social and cognitive development, and secondary factors that could have affected development or weight in childhood. Purpose: To support a more holistic and trauma-informed approach to nursing care, a systematic review was conducted examining the relationship between parent ACEs and offspring development and health status. Method: A literature review was conducted over 20 peer reviewed articles found on CINAHL Complete, PubMed and MEDLINE (Ebsco) databases. Results: A summary of the literature suggests an association between parent ACEs and offspring overall health impacts. Conclusion: The influence of parent ACEs on parenting styles and parent-child interactions, elicits an array of negative impacts on offspring health outcomes. A lack of relevant studies specifically examining the relationship between parent ACEs and offspring weight status supports the need for more relevant studies and implementation of interventions based on research outcomes

(Counter-)Narratives of Violence. Colonial Legacies and Activism in Italy’s Public Spaces

Even though the Italian colonial empire was relatively small and short-lived (compared to others, such as the British or French), it left numerous material traces in the public spaces of Italian cities. For decades, no one was interested in the monuments and street names that celebrated longgone expeditions and military ventures. Since 2015, however, this has changed. This article examines how dominant discourses of colonial violence manifested in public spaces during the liberal and fascist eras and how collectives have challenged these narratives through the use of various strategies in recent years.Even though the Italian colonial empire was relatively small and short-lived (compared to others, such as the British or French), it left numerous material traces in the public spaces of Italian cities.
