Osteosarcoma is a rare bone cancer which is more common in children than in adults and has a high chance of metastasizing to the patient’s lungs. Due to initiated cases, it is difficult to diagnose and hard to detect the nodule in a lung at the early state. Convolutional Neural Networks (CNNs) are effectively applied for early state detection by considering CT-scanned images. Transferring patients from small hospitals to the cancer specialized hospital, Lerdsin Hospital, poses difficulties in information sharing because of the privacy and safety regulations. CD-ROM media was allowed for transferring patients’ data to Lerdsin Hospital. Digital Imaging and Communications in Medicine (DICOM) files cannot be stored on a CD-ROM. DICOM must be converted into other common image formats, such as BMP, JPG and PNG formats. Quality of images can affect the accuracy of the CNN models. In this research, the effect of different image formats is studied and experimented. Three popular medical CNN models, VGG-16, ResNet-50 and MobileNet-V2, are considered and used for osteosarcoma detection. The positive and negative class images are corrected from Lerdsin Hospital, and 80% of all images are used as a training dataset, while the rest are used to validate the trained models. Limited training images are simulated by reducing images in the training dataset. Each model is trained and validated by three different image formats, resulting in 54 testing cases. F1-Score and accuracy are calculated and compared for the models’ performance. VGG-16 is the most robust of all the formats. PNG format is the most preferred image format, followed by BMP and JPG formats, respectively.

Статья посвящена археологическим находкам металлических деталей головных уборов. Диадемы в виде длинных узких лент появляются на Ближнем Востоке во второй половине IV тыс. до н. э. В III тыс. до н. э. вырабатываются другие типы головных украшений, среди которых простые овальные и ромбовидные налобные бляхи и сложные конструкции с дополнительными деталями. Соответствующие находки рассматриваются как маркеры высокого социального статуса, связанные с процессом формирования элитарных групп в догосударственных и раннегосударственных обществах Месопотамии и Анатолии. The article is focused on the archaeological finds of headdress details made of metals. The diadems in the shape of long narrow bands appeared in the Near East in the second half of the 4th millennium BC. In the 3rd millennium BC other types of head ornaments were introduced, among them oval and rhomboidal frontlets and elaborate constructions with additional details. The corresponding finds are considered as markers of high social position related with the process of formation of elite groups in pre-state and early state societies in Mesopotamia and Anatolia.

Study of past changes in environment and, its effect on human society delivers key information to reconstruct the hystorical past but also to project future changes and their effects. Study focus on South-East Georgia, Caucasus region, which represents natural polygon of long term changes in the environment. Study area represents semi-arid Shiraqi plain in South-East Georgia (see the map below). It is characterized with annual precipitation <600mm and shows open dry steppic landscape today. However, recent data collected using remote sensing and archaeological studies, deliver evidences of early human inhabitation of this area, starting from the Paleolithic and forming a constant chain of active settlement through the time, until sudden abrupt at the end of the Bronze Age. Geomorphologically Shiraqi plane represents 800 sqr. km of almost flat area with average height of 600 m above Sea level, surrounded by chains of mountains creating a natural walls surrounding the plane. There are almost no settlements in the area, devoid of water resources today. Archaeo-Botanic and soil studies assume that the region was covered by forests, Hydro modelling shows possibility of existence of well developed water network with a shallow lake in the center of plane. Remote sensing data and resent archaeological excavations at Didnauri site provides clear evidences of early state formation, with favorable paleo-environmental conditions. The goal of current study is to shed light on historic changes in the environment of the region, its natural and anthropogenic factors and consequently response of human society on these changes.

When the 1926 Euclid v. Ambler decision found municipal zoning valid under the U.S. Constitution, previous state cases opposing the practice were overruled and subsequently almost forgotten. This investigation analyzes those early State Supreme Court cases to determine systematically the basis of these rejections. After constructing a contextual background of the legal arguments that could have been used by the judges, I assess cases to determine which were used, and find a dominance of concern regarding land use segregation justified by municipalities through an “aesthetics” defense. I conclude by considering links between these cases and current controversies.

The Ancient Near Eastern powerful states in the mid II millennium BC were not only directing and supervising the military-political, trading-economic, and sociocultural processes, but were also trying to obtain their dominance and control in the region. This was the reason that two conflicting groups gradually polarized in the region, where each state, despite its interests concerning the redistribution of spheres of influence in the ancient Near East, had to ally a more convenient political formation, given the current political situation and its capacities. As a result, the Hittite New Kingdom, Arzawa and Wilusa appeared to be in one of the groups, and the New Kingdom of Egypt, Kassite Babylonia and Mitanni were in the other one. The inter-state relations of these powers included both military-political and diplomatic rivalry, and a controlled system of well-organized transit trading and cultural relations. At the same time, each of the groups sought to urge other small early state organizations and tribal unions of the region to get involved in the alliance, contributing to the realization of prospective political plans with their capacities of raw materials, production of specific items and human resources. This was the situation also with the part of the early state organization of the Armenian Highland. Meanwhile, both the written sources and the archaeological excavations in general, testify the anti-Hittite orientation of the early state organizations of the Armenian Highland and their tending towards Egypt-Mitanni-Kassite Babylonia alliance.

Old Russian texts provide an opportunity to study the early state of the Russian vocabulary. The vocabulary structure of the Old Russian texts included the words of the Proto-Slavic language, a large number of calques and artificially created words. The absence of written records of the Proto-Slavic language, in which its vocabulary would be recorded, deprives us of the primary source of the meanings of such words. The Proto-Slavic root *lěp- had an undivided meaning. Undivided meaning of the root *lěp- is a potential problem in the interpretation of the words with this root used in ancient Russian texts. Another problem in the lexical-semantic study of words in the Old Russian texts is that words being semantic calques received additional meanings under the influence of Greek. In this regard the paper shows the formation of the concept of beauty in words with the root *lěp- used in ancient Russian texts. The purpose of this article is to study the evolution of the concept of beauty in the words with the Proto-Slavic root *lěp-. The article provides a comparative analysis of lexical meanings of the words with the root *lěp- containing the concept of beauty (used in ancient Russian texts) with their Greek equivalents. Such words are contained in ancient Russian written records: “The Life of St. Andrew the Fool”, “The Chronicle” by John Malalas, “The Chronicle” by George Amartol, “History of the Jewish War” by Josephus Flavius, Christianopolis (Acts and Epistles of the Apostles), Uspensky Сollection of XII–XIII centuries, etc.
