The article considers the historical and cultural heritage of villages of the former Ketskaya volost, which is currently a part of the Tomsk region. The formation of Ketsky prison and the architecture of large settlements of the former Ketskaya volost are studied. Little is known about the historical and cultural heritage of villages of the Tomsk region and the problems of preserving historical settlements of the country.The aim of this work is to study the formation and development of the village architecture of the former Ketskaya volost, currently included in the Tomsk region.The following scientific methods are used: a critical analysis of the literature, comparative architectural analysis and systems analysis of information, creative synthesis of the findings. The obtained results can be used in preparation of lectures, reports and communication on the history of the Siberian architecture.The scientific novelty is a study of the historical and cultural heritage of large settlements of the former Ketskaya volost, which has not been studied and published before. The methodological and theoretical basis of the study is theoretical works of historians and architects regarding the issue under study as well as the previous  author’s work in the field.It is found that the historical and cultural heritage of the villages of the former Ketskaya volost has a rich history. Old historical buildings, including religious ones are preserved in villages of Togur and Novoilinka. The urban planning of the villages reflects the design and construction principles of the 18th century. The rich natural environment gives this area a special touch.

Multispectral photoacoustic imaging is a powerful noninvasive medical imaging technique that provides access to functional information. In this study, a set of methods is proposed and validated, with experimental multispectral photoacoustic images used to estimate the concentration of chromophores. The unmixing techniques used in this paper consist of two steps: (1) automatic extraction of the reference spectrum of each pure chromophore; and (2) abundance calculation of each pure chromophore from the estimated reference spectra. The compared strategies bring positivity and sum-to-one constraints, from the hyperspectral remote sensing field to multispectral photoacoustic, to evaluate chromophore concentration. Particularly, the study extracts the endmembers and compares the algorithms from the hyperspectral remote sensing domain and a dedicated algorithm for segmentation of multispectral photoacoustic data to this end. First, these strategies are tested with dilution and mixing of chromophores on colored 4% agar phantom data. Then, some preliminary in vivo experiments are performed. These consist of estimations of the oxygen saturation rate (sO2) in mouse tumors. This article proposes then a proof-of-concept of the interest to bring hyperspectral remote sensing algorithms to multispectral photoacoustic imaging for the estimation of chromophore concentration.
