Oybek Narzulloyev, Xolida Hasanova Ravshanbek Xidirov — 2026-03-30

This study aims to study the concept of fractal geometry in the Uzbek national ganch carving patterns on the walls of the Registan mausoleums using the Lindenmayer system (L-systems).

THE ROLE AND SIGNIFICANCE OF STATE PROGRAMS IN DEVELOPING THE NATIONAL CONSTRUCTION INDUSTRY AND STIMULATING DIVERSIFICATION PROCESSES

Maraimova K.Sh. — 2026-04-17

This article examines the development of the national construction industry in the context of New Uzbekistan, with particular emphasis on accelerating product diversification processes in construction enterprises. Special attention is paid to improving the system of technical regulation and standardization, establishing the “Uzbekistan Building Code (UBC)”, introducing a national classifier of construction resources, and implementing the industrial mortgage mechanism as a tool of state support.

ANALYSIS OF REGULATORY, LEGAL, AND INSTITUTIONAL REFORMS IN THE FIELD OF CRYPTOCURRENCY CIRCULATION IN UZBEKISTAN

Shoakhmedova Nozima Khayrullayevna — 2026-04-15

This study analyzes regulatory, legal, and institutional reforms in the field of cryptocurrency circulation in Uzbekistan.

CLINICAL SIGNIFICANCE OF NITRIC OXIDE AND L-ARGININE DISTURBANCES IN CHILDREN WITH ACUTE VIRAL HEPATITIS C

Khalikova Sh.A — 2026-04-14

Acute viral hepatitis C in children remains a clinically important problem
because of its heterogeneous course, metabolic consequences, and potential for
severe liver dysfunction. In recent years, nitric oxide (NO) has attracted growing
attention in hepatology due to its broad role in intracellular homeostasis and
bioregulatory processes.

KARNAUGH MAPS, SOLUTION TREES, AND LOGIC

Jurayeva N.Yu. — 2026-03-30

This paper explores the fundamental principles and practical applications of Karnaugh maps, solution trees, and logical reasoning in the field of discrete mathematics and computer science. Karnaugh maps are presented as an effective graphical tool for simplifying Boolean expressions and minimizing logical functions, which is essential in the design of digital circuits. Solution trees are examined as a structured method for representing decision-making processes, algorithmic thinking, and problem-solving strategies. The study highlights how these tools contribute to the development of logical thinking skills among students, particularly in areas such as information security, programming, and system design. Through theoretical analysis and illustrative examples, the paper demonstrates the interconnection between these concepts and their role in optimizing computational processes and improving analytical reasoning.

DESIGNING EFFECTIVE LOGISTICS CHANNELS FOR OPTIMIZING OPERATIONAL PROCESSES IN ENTERPRISES

Dusiyarov Asrbek Uktamovich — 2026-04-16

In modern economic conditions, enterprises are increasingly required to enhance efficiency, reduce operational costs, and maintain competitiveness in dynamic markets. One of the most critical factors influencing these objectives is the structure and effectiveness of logistics channels. This paper examines the role of logistics channel design in optimizing operational processes within enterprises. It explores key components such as transportation, warehousing, inventory management, and information flow, emphasizing their integration into a unified logistics system. The study highlights how properly designed logistics channels can minimize delays, reduce costs, and improve service quality.

ANALYSIS OF THE CRYPTOCURRENCY INDUSTRY BASED ON INTERNATIONAL EXPERIENCE AND THE PRINCIPLES OF ITS OPERATION

Shoakhmedova Nozima Khayrullayevna — 2026-04-15

This study analyzes the cryptocurrency industry based on international experience and examines the fundamental principles of its operation. Over the past decade, the cryptocurrency industry has become an important part of the global financial system and has contributed to the rapid development of the digital economy. The industry operates primarily on blockchain technology, which ensures decentralized data storage, transparency, security, and reliability of financial transactions without the need for central governing institutions. The paper examines international regulatory approaches to the crypto industry in countries such as the United States, the European Union, Japan, China, and South Korea, highlighting differences in regulatory frameworks, investor protection mechanisms, and market control policies. The study also explains the main operating principles of the crypto industry, including blockchain technology, consensus mechanisms such as Proof of Work and Proof of Stake, crypto wallets, exchanges, and smart contracts. In addition, the research identifies major risks associated with the crypto industry, including price volatility, cybersecurity threats, legal uncertainty, and illegal transactions. The study concludes that balanced regulation, technological infrastructure development, and investor protection are essential for the sustainable development of the cryptocurrency industry and its integration into the global financial system
