Archaeological Excavation and Documentation of Kafir Kala Fortress

The site of Kafir Kala is located in the south-east of modern Samarkand city, Uzbekistan, and well-known for its unique sealings and other artifacts. Since 2013, the Japanese-Uzbek joint archaeological expedition has been carrying out excavations and digital surveys on this site, mainly focusing on the fortress area. This paper is a preliminary presentation of newly excavated pre-Islamic structures and 3D models, contributing to a better understanding of the urban settlement history of pre-Islamic Samarkand, as well as other regions of Central Asia.  

A Journey to the West: The Ancient Dispersal of Rice Out of East Asia.

Funder: Max Planck Institute for the Science of Human HistoryRice is one of the most culturally valued and widely grown crops in the world today, and extensive research over the past decade has clarified much of the narrative of its domestication and early spread across East and South Asia. However, the timing and routes of its dispersal into West Asia and Europe, through which rice eventually became an important ingredient in global cuisines, has remained less clear. In this article, we discuss the piecemeal, but growing, archaeobotanical data for rice in West Asia. We also integrate written sources, linguistic data, and ethnohistoric analogies, in order to better understand the adoption of rice outside its regions of origin. The human-mediated westward spread of rice proceeded gradually, while its social standing and culinary uses repeatedly changing over time and place. Rice was present in West Asia and Europe by the tail end of the first millennium BC, but did not become a significant crop in West Asia until the past few centuries. Complementary historical, linguistic, and archaeobotanical data illustrate two separate and roughly contemporaneous routes of westward dispersal, one along the South Asian coast and the other through Silk Road trade. By better understanding the adoption of this water-demanding crop in the arid regions of West Asia, we explore an important chapter in human adaptation and agricultural decision making

Restoring the function set by integrals for the family of parabolas on the plane

Integral geometry is one of the most important sections of the theory of ill-posed problems of mathematical physics and analysis. The urgency of the problems of integral geometry is due to the development of tomographic methods, which raise the requirements for the depth of the applied results, the fact that the solution of problems of integral geometry reduces a number of multidimensional inverse problems for partial differential problems, as well as the internal development needs of the theory of ill-posed problems of mathematical physics and analysis. In this work we consider the problem of reconstructing a function from a family of parabolas in the upper half-plane with a weight function of a new kind. The uniqueness and existence theorems of the solution of the problem are proved and the inversion formula is derived. It is shown that the solution of the problem posed is weakly ill-posed, that is, stability estimates are obtained in spaces of finite smoothness
