We study the properties of Triangular Tree, a complete tree rational pairs introduced by Bonanno et al. (2021), in analogy with main Farey (or Stern–Brocot tree). To our knowledge Triangular Tree is first g

This article explores informal environmental education (EE) experiences at eco-attractions. A consortium of three UK-based environmental charities designed an eco-attraction-based EE program aiming to inspire responses to environmental change. Over six months, educators at six eco-attractions delivered this two-day program to 430 young people. This article conveys qualitative insights into lear...

The neutral theory of biodiversity (NTB) provides an individual-based modeling framework to study eco-evolutionary dynamics. Previous NTB models usually assumed the same per capita rate of speciation across lineages. However, population dynamics may induce macroevolutionary feedbacks that can result in variable per capita speciation rates across lineages. In this paper, with analytical and simu...

Eco-environmental stress refers to the pressure borne by the environment in sustaining the pre-existing non-industrialized state and/or in counteracting adverse impacts caused by natural and human factors. The present article introduces the concept, research progress, and method for assessing eco-environmental stress. An eco-environmental stress index (ESI) is established to assess the eco-envi...

Metastatic breast cancer is the second leading cause of cancerrelated deaths among women. Triple-negative breast cancer (TNBC) is a highly aggressive subcategory of breast cancer and currently lacks well-defined molecular targets for effective targeted therapies. Disease relapse, metastasis, and drug resistance render standard chemotherapy ineffective in the treatment of TNBC. Because previous ...

In this article, we consider houses belonging to an eco-neighborhood in which inhabitants have the capacity to optimize dynamically the energy demand and the energy storage level so as to maximize their utility. The inhabitants’ preferences are characterized by their sensitivity toward comfort versus price, the optimal expected temperature in the house, thermal loss and heating efficiency of th...

BACKGROUND Cigarette smoking causes cardiovascular disease and activates markers of endothelial dysfunction or injury. We investigated the nailfold capillary blood velocity (NCV) in cigarette smokers compared to non-smokers. METHODS Forty-eight men (eighteen non-smokers and thirty smokers) were recruited. We measured NCV using nailfold capillary microscopy and exhaled carbon monoxide (ECO) co...

Eco-P colonies are constructed as natural extension of P colonies with dynamical evolution of environment. P colonies are one of the kind of computational models based on independent autonomous agents represented by membrane systems working and evolving in a shared environment. These acts are based on the set of program associated with every agent. There are two types of agents in eco-P colonie...
