Intellectual property rights infringement on e-commerce marketplaces: Application of AI technologies, new challenges
Intellectual property rights infringement is a growing concern in the age of e-commerce, where online marketplaces have become the primary platforms for buying and selling goods. As the popularity of e-commerce increases, so does the risk of counterfeit products, unauthorized use of trademarks, and other infringements on intellectual property rights. In response to this challenge, AI technologies have emerged as powerful tools to combat infringement on e-commerce platforms. This article sets out to explore the application of AI technologies in addressing intellectual property rights infringement on e-commerce marketplaces and the new challenges that arise as a result. The article explores the impact of artificial intelligence (AI) technologies on identifying and preventing infringements in e-commerce marketplaces. It delves into the use of automated algorithms and machine learning, highlighting their ability to improve efficiency and accuracy in infringement detection. However, the article also discusses the challenges associated with capturing nuanced infringements through AI technologies. Overall, the study sheds light on the evolving landscape of intellectual property rights protection in the context of e-commerce and emphasizes the significance of AI in addressing these challenges

Today, the unstable political and economic situation in the world has led to an intensified migration and changes in their directions. The legal norms regarding the status of migrants, including people living with HIV, are also changing. Over the past 10 years laws restricting the entry and residence of HIV-infected foreign citizens have been repealed in many countries, but in Russia the deportation and prohibition of long-term stay of HIV positive international migrants are still in effect. This review presents the main aspects of the impact of migration on the spread of HIV in the world and Russia, as well as the possible positive and negative effects of decriminalization of migrants living with HIV in terms of epidemic situation, socio-demographic and economic processes. The argument for retaining the deportation is due to the potential risk of the spread of the disease by foreigners and the unresolved organization of medical care and treatment of HIV infection for foreign migrants, which are provided for Russian citizens from the state budget. On the other hand, the deportation law touches upon ethical aspects, violating freedom of movement, the right to privacy and freedom from discrimination. Despite the presence or absence of restrictive measures against HIV-positive migrants, HIV has spread throughout all countries and led to a global epidemic. Prevention of HIV infection among general population of the country, regardless of their migration status, is a priority on the way to stop the spread of infection.Β ΠΠ° ΡΠ΅Π³ΠΎΠ΄Π½ΡΡΠ½ΠΈΠΉ Π΄Π΅Π½Ρ Π½Π΅ΡΡΠ°Π±ΠΈΠ»ΡΠ½Π°Ρ ΠΏΠΎΠ»ΠΈΡΠΈΡΠ΅ΡΠΊΠ°Ρ ΠΈ ΡΠΊΠΎΠ½ΠΎΠΌΠΈΡΠ΅ΡΠΊΠ°Ρ ΡΠΈΡΡΠ°ΡΠΈΡ Π² ΠΌΠΈΡΠ΅ Π²Π΅Π΄Π΅Ρ ΠΊ Π°ΠΊΡΠΈΠ²ΠΈΠ·Π°ΡΠΈΠΈ ΠΌΠΈΠ³ΡΠ°ΡΠΈΠΎΠ½Π½ΡΡ

Rru_A3730 protein is a bacterial Rhodospirillum rubrum L-asparaginase (RrA), which is known by its anticancer activity. RrA variants with point amino acid substitutions in the region of 150 amino acids residues: RrA17N, K149E, RrAE149R, V150P, F151T, RrΠ17N, E149R, V150P, RrAE149R, V150P, showed antiproliferative properties, and also by their ability to suppress telomerase activity. This work is devoted to comparison of physical-chemical and catalytic properties of these mutant forms of RrA. It is shown that pH optimum is in the alkaline zone (8.5 β 9.3); L-glutaminase and D-asparaginase activity is respectively not more than 0.1% and 1.6% of L-asparaginase for all studied variants of RrA. The presence of the N17-terminal amino acid sequence MASMTGGQMGRGSSRQ of the capsid protein of bacteriophage T7 in the RrA structure leads to an increase in the thermal stability of mutant RrA analogues (from 50Β°C to 56Β°C) and their resistance to denaturation in the presence of 3 β 4 M urea. It is of Metal ions exhibit multidirectional effects on L-asparaginase activity of RrA. K+, Ca2+, Zn2+, Cs+, Co2+ in significantly affect the activity of L-asparaginase, while Mn2+, Cu2+, Fe3+ ions inhibit it. There was no correlation between antitelomerase (antiproliferative) activity and kinetic properties of mutant forms of L-asparaginase RrA.ΠΠ΅Π»ΠΎΠΊ Rru_A3730, ΠΈΠ·Π²Π΅ΡΡΠ½ΡΠΉ ΠΊΠ°ΠΊ Π±Π°ΠΊΡΠ΅ΡΠΈΠ°Π»ΡΠ½Π°Ρ L-Π°ΡΠΏΠ°ΡΠ°Π³ΠΈΠ½Π°Π·Π° Rhodospirillum rubrum, ΠΏΡΠ΅Π΄ΡΡΠ°Π²Π»ΡΠ΅Ρ ΠΈΠ½ΡΠ΅ΡΠ΅Ρ Π² ΠΊΠ°ΡΠ΅ΡΡΠ²Π΅ ΠΏΠΎΡΠ΅Π½ΡΠΈΠ°Π»ΡΠ½ΠΎΠ³ΠΎ ΠΏΡΠΎΡΠΈΠ²ΠΎΠΎΠΏΡΡ

Transition from Townsend to glow discharge: subcritical, mixed or supercritical
The full parameter space of the transition from Townsend to glow discharge is
investigated numerically in one space dimension in the classical model: with
electrons and positive ions drifting in the local electric field, impact
ionization by electrons ( process), secondary electron emission from
the cathode ( process) and space charge effects. We also perform a
systematic analytical small current expansion about the Townsend limit up to
third order in the total current that fits our numerical data very well.
Depending on and system size pd, the transition from Townsend to glow
discharge can show the textbook subcritical behavior, but for smaller values of
pd, we also find supercritical or some intermediate ``mixed'' behavior. The
analysis in particular lays the basis for understanding the complex
spatio-temporal patterns in planar barrier discharge systems.Comment: 12 pages, 10 figures, submitted to Phys. Rev.

A case of progressive multifocal leukoencephalopathy in a HIV-infected female patient
Progressive multifocal leukoencephalopathy (PML) caused by JC virus is a severe central nervous lesion developing in the presence of obvious immunodeficiency. In most cases, the disease results in a fatal outcome within a few months. Antiretroviral therapy is currently considered to be the only method for the prevention and treatment of PML in HIV-infected patients. The paper describes a positive experience in treating the HIV-infected female patient with the established diagnosis of PML
