In this study I will analyse the growth of an urban cluster resulting from interaction with a dynamic spatial pattern comprised of cells and roads. In this case, the cells grow in an irregular pattern and can change in number and state, and the roads direct the growth pattern of the urban cluster and stimulate cell generation. The coupled effects of a cellular mechanism and a road network and the long-distance effects determined by spatial mobility are presented in two forms: first in a theoretical framework, and then through numerical simulation in which various sets of key parameters are utilised. A model is proposed in which growth is related to the fractal dimension of the cluster. Finally, conclusions are drawn for the long-run effects of morphology modification in relation to land use and to spatial pattern.

We show that for a heavy vector-like quark model with a down type isosinglet, branching ratio for [Formula: see text] decay is enhanced by more than [Formula: see text] as compared to that in the Standard model when QCD corrections to next-to-leading order are incorporated. In a left–right symmetric model (LRSM) along with a heavy vector-like fermion, enhancement of this order can be achieved at the bare (QCD uncorrected) level itself. We propose that a measurement of the photon polarization could be used to signal the presence of such new physics in spite of the large long distance effects. We find that there is a large region within the allowed parameter space of the model with a vector-like quark and an additional left–right symmetry, where, the photon polarization can be dominantly right-handed.

In postmodern times of emphasized fluidification, individualism and cosmopolitanism, mobility becomes self-evident and naturalized, yet socially desirable and anticipated. Therefore it is valuable to use ethnography to look at individual experiences. They are young, educated, and mobile, pursuing their dreams and goals while living in big cities: Poles and other (not only) European citizens who maintain transnational long-distance relationships create perfectly suitable representatives of the category of ‘privileged mobility’. This article is based on ethnographic fieldwork I conducted in 2016–2018, and it employs an auto-ethnographic perspective in order to examine the notion of privilege (Amit 2007), with its borders and limitations, through the analytical lens of mobility. The article puts forward the perspective of my research participants and thus provides a detailed portrait of the researched group, in order to show how mobility is rooted in their everyday lives and how privileged they really are. I argue that mobility, defined as one of the most stratifying factors (Bourdieu 1984), can be applied as a mirror that reflects position in the social strata. In this specific ethnographic context, spatial mobility can be seen as a useful tool, which exposes social and individual dimensions of being privileged while living in transnational long-distance relationships

Pacitan Regency has the potential natural tourism because in the south is adjecent to the Indian Ocean and that region has many caves. The number of tourists visit in Pacitan Regency has recently increased, especially in 2017 is the highest number of tourists visit. Spatial pattern of tourist distribution can be analyzed based on terrain, type of network and the distance from city center. The purpose of this study is analyzing spatial pattern of tourist distribution based on physical factor (terrain) and accessibility factors (type of road network and the distance from city center) then the factors that have significant relation. The data are collected by observation, interview, plotting, and documentation. The method used in this research was descriptive and statistics. The tourists distribution in this research are total of tourist arrivals 2017 in tourism object that registered by the department of tourism, youth, and sport of Pacitan Regency. The result shows the highest tourist distribution is on Teleng Ria Beach and Klayar Beach. Teleng Ria Beach is on flat terrain, located on local road and near from city center of Pacitan Regency. Klayar Beach is on undulating terrain, located on other road and moderate from city center of Pacitan Regency. The highest tourist distribution in Teleng Ria Beach and Klayar Beach are reinforced with the most complete primary, secondary and conditional facilities among other tourism objects in Pacitan Regency. Statistics show significant relation between tourist distribution and physical factor (terrain).

Recently several developments have taken place in the lattice QCD calculations of hadronic factors in the case of [Formula: see text] and the [Formula: see text] mixings along with contribution of the long distance effects in the [Formula: see text] system. These have led some authors (Refs. 12 and 13) to point towards the possibility of New Physics (NP) in these systems to the tune of 20% or so. However, the present analysis, based on essentially NP free inputs and incorporating constraints of unitarity, shows that in case the NP effects are there in the parameters associated with these systems, e.g. sin 2β, Vtd, ϵK, etc., these seem to be only at a few percent level.
