Complexity: against systems [PDF]

Theory in Biosciences, 2011
This article assumes a specific intuitive notion of complexity as a difficulty to generate and/or assess the plausibility of models. Based on this intuitive understanding of complexity, it identifies two main causes of complexity, namely, radical openness and contextuality. The former is the idea that there are no natural systems.

Planning an Healthcare Network: the case of Clinical Laboratories in Sicily

, 2014
Healthcare centers, private and public, are responsible for serving health demand of the population. Typically their respective geographical location and size is the result of a complex interaction between epidemiological, historical and economical ...

Wavefront Shaping with Varying Degrees of Freedom [PDF]

EPJ Web of Conferences
Optical wavefront shaping employs the linearity of scattering to focus light through scattering media using spatial modulation. By selectively switching off weakly-contributing segments, we significantly improve optimization speeds with minimal intensity

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.

Large-Scale Modeling of Economic Systems

, 2013
Following the events of the credit crunch and the onset of a global reces- sion, alternative ways of modeling modern economies and mechanisms for carrying out policy analysis are now an urgent priority. Traditional mathematical economics is widely viewed

Complexity and fragility in system of systems

International Journal of System of Systems Engineering, 2016
SoS are an ensemble of complex systems, which have the potential for an extraordinary amount of structural complexity, even temporarily, as a result of interconnections and couplings that can vary in strength. Because of this, SoS can be vulnerable to sudden catastrophic collapse as a result of small and insignificant partial functionality losses in ...

Narrativity in complex systems [PDF]

, 2021
Humans use narrative for making sense of their environment. In this chapter we ask if, and if so how and to what extent, our narrative mind can help us deal scientifically with complexity. In order to answer this question, and to show what this means for

Evidence‐Informed Multidisciplinary Consensus Guidance for the Psychosocial Care of Adolescents With High‐Risk Cancer: Recommendations From the Italian Association of Pediatric Hematology and Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adolescents with high‐risk cancer face complex developmental, psychosocial, and ethical challenges that extend beyond disease‐directed treatment. Although international recommendations exist for communication, psychosocial care, pediatric palliative care, survivorship, and shared decision‐making, these have largely evolved within ...

Statistical scaling laws for competing biological species

, 2018
Universality classes are defined for an idealized nonlinear system that governs the competition between biological species. The decay to asymptotic steady state is examined for supercritical Hopf bifurcation by considering a phenomenological approach ...

Predicting transitions across macroscopic states for railway systems [PDF]

, 2019
Railways are classic instances of complex socio-technical systems, whose defining characteristic is that they exist and function by integrating (continuous-time) interactions among technical components and human elements.
