General Relativity and Gravitation, 2003 We show that with the help of a suitable coupling between dark energy and cold dark matter it is possible to reproduce any scaling solution $ _{X}\propto _{M}a^ $, where $ _{X}$ and $ _{M}$ are the densities of dark energy and dark matter, respectively. We demonstrate how the case $ = 1$ alleviates the coincidence problem. Future observations of

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Patients with high‐risk neuroblastoma who either are refractory to induction chemotherapy or relapse following multi‐modal treatment have a dismal prognosis. Based on data from the BEACON trial, since 2021 the UK national guidelines recommend bevacizumab, irinotecan, and temozolomide (BIT) for patients with relapsed/refractory ...

Living Structure as an Empirical Measurement of City Morphology
ISPRS International Journal of Geo-Information, 2020 Human actions and interactions are shaped in part by our direct environment. The studies of Christopher Alexander show that objects and structures can inhibit natural properties and characteristics; this is measured in living structure.

Evaluation of the corrosion and scaling potential of the drinking water sources in Neyshabur city, Iran based on stability indices (2017) [PDF]
Journal of Advances in Environmental Health Research, 2019 Corrosion is a physical and chemical reaction between materials and the surrounding environment, which causes changes in the properties of the material and may lead to the financial loss of pipes, as well as other transmission and distribution facilities.

Multidimensional scaling [PDF]
WIREs Cognitive Science, 2012 AbstractThe concept of similarity, or a sense of ‘sameness’ among things, is pivotal to theories in the cognitive sciences and beyond. Similarity, however, is a difficult thing to measure. Multidimensional scaling (MDS) is a tool by which researchers can obtain quantitative estimates of similarity among groups of items.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Alveolar soft part sarcoma (ASPS) is a rare soft tissue sarcoma occurring most commonly in adolescence and young adulthood. Methods We present the clinical characteristics, treatments, and outcomes of patients with newly diagnosed ASPS enrolled on the Children's Oncology Group study ARST0332.

The European Physical Journal C, 2018 We present a new correspondence between a d-dimensional dynamical system and a whole family of (d+1)-dimensional systems. This new scale-holographic relation is built by the explicit introduction of a dimensionful constant which determines the size of the additional dimension.
