In silico study for discovering novel thiazole derivatives as anti-breast cancer agents (MCF-7)
The work validated the pharmacokinetic characteristics and docking approach, and discovered novel thiazole compounds with MCF-7 breast anti-cancer efficacy using quantitative structure-activity relationships (QSAR) models. Using an experimental dataset of 53 thiazole derivatives with IC50 values, QSAR models were developed using multivariate linear regression (QSARMLR) and artificial neural networks (QSARANN). Eight descriptions, with statistical values of R2train = 0.875 and Q2LOO = 0.834, comprised the successfully developed QSARMLR model. Based on the descriptors of the QSARMLR model, which has statistical values of R2 = 0.918, Q2test = 0.934, and Q2CV = 0.916, the QSARANN neural network model with the architectural network of I(8)-HL(9)-O(1) has also been constructed. Using the AD and outliers analysis, the models were utilized to forecast 120 new design derivatives based on the thiazole framework, and the IC50 values of 10 new thiazole derivatives were determined. Additionally, the derivatives were assessed for resistance to estrogen-positive breast cancer by docking them onto the Polo-like kinases (Plk1) receptor and screening them for pharmacokinetic features in accordance with Lipinski and Ghose guidelines. Consequently, it was discovered that the thiazole TAZ5 had promising derivative activity against the primary MCF-7 breast cancer cell line.
Employing artificial neural networks for the assessment of the aqueous solubility of drug –like substances
This research has advanced Quantitative Structure-Property Relationship (QSPR) models for predicting the aqueous solubility of drug-like substances. By integrating multivariate regression and neural network techniques, the study utilized the backward algorithm to strategically select 2D and 3D molecular descriptors, resulting in the development of an optimal QSPRMLR model with k = 23. The artificial neural network regression model (QSPRANN), derived from selected descriptors of the multivariable linear regression model (QSPRMLR), demonstrated enhanced predictive capabilities for logS values in both validation and prediction groups, yielding SE values of 0.786 and 0.808, respectively. The QSPRANN significantly improved the overall predictability of the multivariate regression model. Statistical assessments of the QSPRANN model revealed SE = 0.699, R2train = 0.918, and Q2v = 0.878. The predicted logS values from the QSPRANN model align well with experimental data, confirming the reliability and accuracy of the developed model.

Optimization of energy management in parallel hybrid vehicles based on dynamic programming algorithm
In this paper, the P&O algorithm in the technique of controlling maximum power point trackers applied in inverters to obtain the maximum power generated from the solar system is presented. Solar panels have non-linear voltage and current characteristics that depend on temperature and irradiance reaching PV panels and PV arrays have a unique point of being able to generate power maximum at each time point. The characteristics of solar radiation reaching the photovoltaic system are not stable at sunny times of the day, it is often changed by other factors such as partial cloud cover, total cloud cover or intensity, radiation varies by hour, by day and by season. As a result, the conversion of photovoltaic energy into electricity of PV panels will be changed. The power generated by the PV system is unstable, leading to low conversion efficiency. The application of algorithms in MPPT control technique to find the point that can generate the maximum power at any time in order to maximize the power received from the solar system. This paper will present simulation results to prove the correctness of the proposed method.

Enhancing Legislation to Combat "Transfer Pricing" for Foreign-Invested Enterprises in Vietnam
Since the enactment of the Law on Foreign Investment in Vietnam in 1987, the state has created favourable conditions for foreign investors to invest in Vietnam, bringing various benefits such as capital, technology, and employment opportunities. However, foreign investors, in their investment activities in Vietnam, have engaged in "transfer pricing," leading to revenue loss for the Vietnamese budget. Transfer pricing is not a new phenomenon in today's economic development; as early as 2012, certain FDI enterprises, like Coca-Cola, Pepsico, Adidas, and Metro, were suspected of engaging in transfer pricing due to continuous reported losses while expanding their business operations. Vietnam has gradually recognized and adjusted transfer pricing activities. Currently, the legal framework for combating transfer pricing is primarily stipulated in Decree 132/2020/ND-CP, which regulates tax management for enterprises with related-party transactions (hereinafter referred to as Decree 132/2020/NDCP). This article analyzes the nature of transfer pricing and its impact and proposes improvements to the relevant legal provisions on control “transfer pricing”.

Contractual obligations in Civil Law of Ukraine: Executive points
The article explores the theoretical aspects of terminating civil obligations, emphasizing the unique role of contracts as legal facts. It asserts that contracts, established by parties in a legal transaction, serve as independent foundations for initiating, modifying, or terminating legal relations. The terms of civil contracts create distinct mechanisms for rightful termination, aligning with legal models for the occurrence of right-terminating legal facts. The author highlights the dependency of contractual obligations on the lawful intent of the involved party or objective circumstances, prescribed by the legal model in the contract. When these models align with actual events, they lead to the realization of parties' expectations and the termination of obligations. These legal facts contribute to the regulatory function of the law, ensuring the fair exercise of rights and interests as defined in the contract. The article provides a detailed list of such legal structures and conducts a legal analysis of their implications
