Data block

The article discloses methodological approaches to quantifying the level of penetration of block chain technologies into the regional socioeconomic environment in comparison to the supply chain strategies. Based on the methods of mathematical and statistical analysis, it allows you to formalize and convert a large array of data of a qualitative order into a single scale for measuring the process under study - the level of demand in the regional socio-economic environment for block chain technology.

The tectonic evolutionary history between the Xing’an Block (XB) and Songnen Block (SB) in the eastern Central Asia Orogenic Belt (CAOB) has been hotly debated. In this study, we present a series of new data to provide a better constraint on the magmatic process during plate subduction and its implications for the regional tectonic evolution of XB and SB, even the CAOB. The whole-rock geochemistry and zircon U-Pb chronology of syenogranite in the Chaihe area of the Great Xing’an Range have been carried out.

The middle-upper Eocene Kırkgeçit Formation, the fossil content of which is the subject of this study, is deposited in a back-arc basin controlled by block-faulting. The Kırkgeçit basin is interpreted as being formed under an extensional regime related to convergence between the Anatolian plate in the north and the Arabian plate in the south.

Transtensional faults are well developed in the S Block of the South Asia area, which have an important impact on the hydrocarbon accumulation. However, the transtensional fault structure is very complex. Based on drilling and seismic data interpretation results, faults are divided into three typical types in the Lower Cretaceous, which can help to understand the complex fault system. The main faults are distributed in the NNW-SSE direction and parallel arrangement with dextral strike-slip shear characteristics, which determines the development of the tectonic belt.

The morphotectonic features of the TGFZ and the distribution of the epicenters of earthquakes over magnitude 5.0 show that this fault zone remains active today. In this study, the deformation of the TGFZ is determined with high sensitivity using geodetic measurements. To obtain accurate information about the deformation of the TGFZ, 24 GNSS sites and two continuously operating reference stations were constructed in the southern part of the TGFZ. Between 2018 and 2020, Global Navigation Satellite Systems (GNSS) measurements were made on this network.

In this study, the method based on the proposed deep-learning method called ODC-Cloud, which was built on convolutional blocks and integrating with the Open Data Cube (ODC) platform. The results showed that our proposed model achieved an overall 90% accuracy in detecting cloud in Landsat 8 OLI imagery and successfully integrated with the ODC to perform multi-scale and multi-temporal analysis.

Với sự bùng nổ của Mạng trung tâm dữ liệu (Data center network), làm cho các hoạt động kinh doanh, sản xuất cũng như các dịch vụ đa phương tiện, các ứng dụng mạng ngày càng phụ thuộc vào nó. Điều này đòi hỏi các nhà cung cấp hạ tầng phải đảm bảo hệ thống mạng trung tâm dữ liệu phải có độ tin cậy và sẵn sàng cao để duy trì tính liên tục cho hệ thống. Tuy nhiên việc đánh giá độ tin cậy và tính sẵn sàng cho hệ thống chỉ mới dừng ở mức đầu tư trang thiết bị và xây dựng hệ thống dự phòng nóng.

This paper presents an image data hiding algorithm composing two models of frequency and image spaces. In comparison of well-known algorithms this algorithm can support high capacity for each image block, robustness and cryptographic security. By dicrete cosine transfer DCT, we transfer from image spaces to frequency space, using EO. algorithm to take middle frequency space, make 0, 1 matrix to hidding data, using Cheng-pan- Tseng algorithm to hidding , using invert dicrete cosine transfer rDCT to transfer image space, so the image has hidding data.

Another class of linear codes, known as Convolutional codes. We study the structure of the encoder. We study different ways for representing the encoder.Convolutional codes offer an approach to error control coding substantially different from that of block codes. A convolutional encoder: encodes the entire data stream, into a single codeword. does not need to segment the data stream into blocks of fixed size (Convolutional codes are often forced to block structure by periodic truncation). is a machine with memory.

HIV-1 efficiently infects susceptible cells and causes AIDS in humans. Although HIV can also enter the cells of Old World monkeys, it encoun-ters a block before reverse transcription. Data have shown that this species-specific restriction is mediated by tripartite motif (TRIM)5a, whose molecular function is still undefined.
