Weak Gravity Conjecture and Holographic Dark Energy Model with Interaction and Spatial Curvature [PDF]

, 2010
In the paper, we apply the weak gravity conjecture to the holographic quintessence model of dark energy. Three different holographic dark energy models are considered: without the interaction in the non-flat universe; with interaction in the flat ...

Modulation of Kekul\'e adatom ordering due to strain in graphene [PDF]

, 2017
Intervalley scattering of carriers in graphene at `top' adatoms may give rise to a hidden Kekul\'e ordering pattern in the adatom positions. This ordering is the result of a rapid modulation in the electron-mediated interaction between adatoms at the ...

Scale‐dependent intraspecific competition of Taurus cedar (Cedrus libani A. Rich.) saplings in the Southern Turkey

Ecology and Evolution, 2019
Better understanding of the competitive interaction at the early development stages of the stand is crucial to help schedule silvicultural treatments for young stands and for the better management of the future stands. We used scale‐dependent analysis to

Research on the Interactive Relationship of Spatial Expansion between Estuarine and Coastal Port Cities

Land, 2023
In both developed and developing countries, port-city relationships have always attracted much attention. However, in the port–city interface, views differ as to whether the port drives the city or vice versa.

An Explicit Spatial Approach to the Value of Local Social Amenities in Metro and Non-Metro Counties in the U.S.: Implications for Comprehensive Wealth Measurement

Land, 2023
This study extends and reinterprets Roback’s general spatial equilibrium model by casting it within the comprehensive wealth framework. Considering the explicit spatial effects among regions, the analysis refines estimates of the contribution of natural,

The Effect Of Omitted Spatial Effects And Social Dependence In The Modelling Of Household Expenditure For Fruits And Vegetables [PDF]

, 2014
We find the omitted elements of the external environment affect negatively the estimates for other spatial (social) effect parameters. Especially, we notice the overestimation of the random effect variance when the social dependence is omitted and the ...
