Refugees from Syria and Iraq in Sweden: resettlement during the migration crisis

The vast increase in the number of forced migrants during the European migration crisis has compelled the receiving countries to concentrate on the issues of migrant reception and accommodation. This study aims to demonstrate how the patterns of settlement of Syrian and Iraqi migrants changed in 2014-2019. We propose a new methodology, building on the Her­findahl-Hirschman index, an indicator of the level and direction of the spatial concentration - deconcentration of migrants, and the Ryabtsev index, which is used to measure the proximity between the settlement structures of migrants and the Swedes. It is established there was a deconcentration of migrants during the crisis (espe­cially in its ascendant phase), carried out by the Swedish authorities. However a reverse process took place in the descendant phase, as a result of self-arranged migrants’ resettlement. The deconcentration of Iraqis and Syrians led to the convergence between the settlement structure typical of immigrants and the Swedes, whilst concentration resulted in divergence accompanied by the emergence of close-knit immi­grant communities on the outskirts of Sweden’s largest cities. The formation of such communi­ties, seen as vulnerable by the national authorities and marked by a high crime rate, impedes the integration of Syrian and Iraqi immigrants into Swedish society

Intermittent Development of Central Place Systems: The Dynamics of Unification and Breakup

Relevance. The development of central place theory has been hindered by its static nature, as it fails to capture transitions between equilibrium states in central place systems. This long-standing problem remains unsolved since the theory's inception 90 years ago. This article presents a solution by examining the cases of system unification and system breakup, where previously independent systems merge or split.Research objective: The study aims to identify the conditions under which central place systems resume continual development following revolutionary transformations in their structure.Data and methods: The research analyzes census data from India (1947-2011) and Yemen (1973-2004) using equations based on the axioms of central place theory. The study also considers isostatic equilibrium as the foundation of central place system structures.Results: The effect of intermittence on the steady evolution of a central place system diminishes rapidly after the unification of two independent systems. In contrast, the adaptation of elements from a previously unified system to new conditions, including reinstating the former hierarchy and spatial structure, takes significantly longer after a system breakup. The study introduces a novel perspective, highlighting that the unification of central place systems tends to lead to progress, whereas the breakup of a unified system results in degradation.Conclusions: The true benefit to a central place system lies not solely in achieving isostatic equilibrium but in maintaining a secure and optimal structure. While these concepts share similarities, they may appear more distinct when examining the central place system as a whole. Equilibrium represents an optimal state for individual hierarchy levels rather than the entire system

К ОЦЕНКЕ РЕЗУЛЬТАТОВ ФОТОДИНАМИЧЕСКОЙ ТЕРАПИИ РАКА КОЖИ

TThis article presents the results of treatment of skin cancer by photodynamic therapy. The aim of this work was to investigate the efficacy of treatment for skin cancer of different locations in anatomically difficult areas and multiple primary and recurrent forms. Tumor complete regression was achieved in 88,6% of cases. Results of treatment of basal cell and squamous cell carcinoma were similar in the number of cases of complete regression and partial regression of lesions. The treatment of primary tumors anatomically difficult areas of complete response was achieved in 81,3 % of patients, and we avoided surgery.Отражены результаты лечения рака кожи методом фотодинамической терапии. Целью данного исследования явилось изучение эффективности метода в лечении рака кожи различных локализаций в анатомически сложных областях, а также при первично-множественных и рецидивных формах. Полная регрессия опухоли была достигнута в 88,6% случаях. При сравнении результатов лечения базально-клеточного и плоскоклеточного рака значимых различий по количеству случаев полной и частичной регрессии очагов не выявлено. При лечении первичных опухолей анатомически сложных областей полной регрессии удалось достичь у 81,3% пациентов, что позволило избежать возможной хирургической операции.

Free-energy distribution functions for the randomly forced directed polymer

We study the $1+1$-dimensional random directed polymer problem, i.e., an elastic string $\phi(x)$ subject to a Gaussian random potential $V(\phi,x)$ and confined within a plane. We mainly concentrate on the short-scale and finite-temperature behavior of this problem described by a short- but finite-ranged disorder correlator $U(\phi)$ and introduce two types of approximations amenable to exact solutions. Expanding the disorder potential $V(\phi,x) \approx V_0(x) + f(x) \phi(x)$ at short distances, we study the random force (or Larkin) problem with $V_0(x) = 0$ as well as the shifted random force problem including the random offset $V_0(x)$; as such, these models remain well defined at all scales. Alternatively, we analyze the harmonic approximation to the correlator $U(\phi)$ in a consistent manner. Using direct averaging as well as the replica technique, we derive the distribution functions ${\cal P}_{L,y}(F)$ and ${\cal P}_L(F)$ of free energies $F$ of a polymer of length $L$ for both fixed ($\phi(L) = y$) and free boundary conditions on the displacement field $\phi(x)$ and determine the mean displacement correlators on the distance $L$. The inconsistencies encountered in the analysis of the harmonic approximation to the correlator are traced back to its non-spectral correlator; we discuss how to implement this approximation in a proper way and present a general criterion for physically admissible disorder correlators $U(\phi)$.Comment: 16 pages, 5 figure
