A Couple of Fresh New Perspectives on the Concatenation Model with Power-Law of Self-Phase Modulation

In this paper, we have secured new optical solitons for the concatenation model with power-law nonlinearity. The traveling wave hypothesis serves as the starting point. To retrieve optical soliton solutions, we have implemented two powerful techniques into the model: the Sardar Sub-Equation Method (SSEM) and the Tanh-Coth method. For power-law nonlinearity, we derived through the balancing principle that solitons would exist for different values of the power-law parameter. Therefore, we have secured a large variety of new soliton solutions for the model. This paper derives dark, bright, and singular soliton solutions for the value of n, as the first case was already covered in a previous report dedicated to addressing the model with Kerr law nonlinearity. Lastly, all the parametric existence conditions of the solitons and all solutions have been constructed.

Use of rational approximations for phonon density of states in evaluation of neutron thermal scattering law

We propose and explore a new analytical formulation for evaluation of Thermal Scattering Law (TSL) using continuous phonon spectra for neutron inelastic scattering. It involves approximating Phonon Density of States (PDOS) in terms of rational approximations in energy transfer. Debye Waller coefficient calculated with these forms are in reasonable agreement with LEAPR calculated values. TSL can be expanded as a power series, each term of which can be integrated analytically. The method leads to TSL being a series of exponential cosine integrals which again have closed rational forms in energy transfer. Their shapes are analogous to asymmetric resonance line shapes and show maxima for certain values of energy transfer which could correspond to phonon emission or absorption. The series is shown to be convergent and easy to compute as it does not involve any numerical integration. The approach is applied to Beryllium metal and Graphite which have vastly different PDOS shapes, and is shown to be capable of giving most of the trends shown by TSL and cross section results from NJOY nuclear code processing system, even with smaller number of power series terms. Since TSL can be calculated for both negative and positive energy transfer with equal ease, one can easily check for the validity of the approximation obeying Principle of Detailed Balance (PDB). The results overall have shown promise of our formulation in making a case for rapid calculations of TSL and also for using the rational forms in energy transfer for analysis of experimental/calculated PDOS data.

Evaluation of underground gas storage capacity in the depleted gas reservoir with water evaporation and salt precipitation

Water evaporation and salt precipitation will occur in gas reservoirs and underground gas storage (UGS) with high-salinity formation water during production and operation. This phenomenon seriously affects the efficient and safe operation and gas storage capacity. This work focuses on quantitatively evaluating the UGS capacity based on depleted gas reservoirs considering water evaporation and salt precipitation. The core flooding experiments are conducted to analyze the influence of water evaporation and salt precipitation on rock properties under different water salinity during multi-cycle injection-production. A numerical model considering water evaporation is established to determine the salt precipitation radius around the gas well. According to the experimental and simulation results, a new analytical model is developed to calculate the underground natural gas storage capacity based on material balance principles. The field case study is presented to show the practical potential of the established model. Both formation porosity and permeability in near-well region may be finally improved by water evaporation and salt precipitation under irreducible water condition. In the presence of movable-water, formation porosity and permeability of the near-well region may be firstly improved and finally reduced due to continuous salt precipitation in porous media. Salt-precipitation radius achieves 28.5 m after ten cycles. The UGS capacity is 101.11 × 108 m3 without considering salt precipitation, 1.11% higher than original geological reserves. The UGS capacity considering both irreducible-water evaporation and salt precipitation is 101.03 × 108 m3. However, when the moveable-water evaporation volume increases to 15Virr, the final UGS capacity is further decreased to 98.55 × 108 m3. The UGS capacity has decreased by 0.82%, 1.64%, and 2.45% compared with irreducible water. The continuous evaporation of movable water and salt deposition will reduce the gas storage capacity and cause damage to the UGS. This work provides an effective method to investigate the quantitative impact of water evaporation and salt precipitation on UGS capacity.

Understanding and Weakening Photon Recycling in Solar Cells to Approach the Radiative Limit.

Photon recycling plays an important role in the light outcoupling of state-of-the-art solar cells and is considered a necessary condition to achieve the radiative limit of open-circuit voltage (VOC) and efficiency. However, due to the impact of photon recycling on bulk and surface radiation of solar cells being overlooked, experimental demonstrations on the accuracy of existing photon recycling models are scarce and some contrary theoretical results also emerge. Here, the relationship between photon recycling and radiation processes, as well as the corresponding VOC losses of solar cells based on the principle of detailed balance is clarified. It is shown that weakening photon recycling is more effective to boost the device performance than enhancing it, promoting the theoretical efficiencies of solar cells, such as perovskite, Si, and GaAs, to 98.5%, 94.9%, and almost 100% of their radiative limit, respectively. Moreover, weakening photon recycling also helps to maintain higher efficiency when the internal radiative efficiency decreases, which benefits higher device stability. This work provides an in-depth understanding of the role of photon recycling in solar cells and helps to push efficiency to a new limit.

Performance of soccer players under acute physical fatigue: An approach based on cognitive, tactical and physical aspects

This study aimed to verify whether peripheral perception, tactical behaviour, and physical performance are influenced by acute physical fatigue in soccer players. The study included 24 trained soccer players (18.6 ± 1.5 years) from two Brazilian clubs. The TSAFT90 test was used to induce acute physical fatigue. The results showed that physical fatigue did not affect peripheral perception (p = 0.360). Regarding tactical behaviour, improved efficiency was observed for the principles of offensive coverage (p = 0.029), width and length with the ball (p = 0.044), and concentration (p = 0.008). On the other hand, a reduction was observed in the number of tactical actions of offensive coverage (p = 0.020) and recovery balance (p = 0.042). Also, improved accuracy in the principles of defensive balance (p = 0.009), recovery balance (p = 0.021) and defensive unity (p = 0.003) occurred under physical fatigue. A reduction in the physical performance outcomes total distance covered (p < 0.001), average speed (p < 0.001), sprints (p = 0.029), number of accelerations (p = 0.008) and decelerations (p = 0.008) were also detected. The internal (p < 0.01) and external (p < 0.01) workload was higher under physical fatigue. Overall, acute physical fatigue did not influence peripheral perception. However, physical performance was reduced under fatigue, the perceived effort increased, and tactical behaviours were affected by decreasing tactical actions performed near the ball, increasing errors in defensive movements in the lateral corridors and the last defensive line, and improving offensive tactical actions performance.

The Legal Regulation of Unfair Competition in the Era of Traffic Flow

On November 22, 2022, the State Administration of Market Supervision and Administration drafted the "Anti-Unfair Competition Law of the People's Republic of China (Revised Draft for Comments)" (hereinafter referred to as the Revised Draft) to solicit opinions from the public. This is another revision since the 'Anti-Unfair Competition Law' came into effect in 2017, and it is also a step forward in the context of the traffic era. The provisions of the 'Internet special provisions' are a major step forward in China's legislation to comply with social development. However, in today's traffic era, new types of unfair competition behaviors emerge in an endless stream. The law itself has a lag, and relying solely on 'Internet special provisions' cannot solve all unfair competition behaviors in the Internet field. Unfair competition in the Internet field has the dilemma of legal application. From the perspective of perfecting the special provisions of the Internet, standardizing the application of the general provisions and the special provisions of the Internet, and giving play to the role of the principle of multi-interest balance, we will promote the legal regulation of unfair competition in the era of traffic.

Study on River Protection and Improvement Based on a Comprehensive Statistical Model in a Coastal Plain River Network

When considering the contradictions between river management and protection in a typical plain river network, it is always confirmed that the river area has usually been encroached upon due to the development of human society. Based on the analysis of multiple attributes of the river network, a statistical model has been proposed in this study in order to determine the river network protection indices such as river area ratio, storage capacity and flux. In this study, a numerical method is proposed to improve the structure and connectivity of the river network by calculating the occupation and supplement balance. According to the principle of water area dynamic balance, the river network structure and its connectivity are improved through water area adjustment in a typical coastal city. As the simulation results show, the water surface ratio equals 8.17%, the storage capacity equals 112.6 million m3 and the water flux equals to 656.06 m3/s in the selected study area. The flood drainage capacity is introduced as the priority function, other functions are also improved due to river management and protection. The harmonious and sustainable coexistence between human society and the river network is then promoted. This comprehensive statistical model proved to be a good tool for the coastal area to enhance the comprehensive attributes of the coastal plain river network and the sustainable development of the local area in the future.

Assessing Power Dynamics: Afghanistan's Constitutional Framework of 2004

This study provides a detailed analysis of the Afghanistan Constitution of 2004, focusing on the principles of separation and balance of powers as outlined in the renowned theory originating from influential political thinkers such as Thomas Hobbes, John Locke, Rousseau, and Montesquieu. The theory of separation of powers has gained widespread acceptance globally, serving as a fundamental tenet of political thought and constitutional law. Through a meticulous examination, this research investigates the incorporation of the theory within the 2004 Afghan constitution, scrutinizing its manifestation across various constitutional provisions. The constitution explicitly delineates executive authority to the government, legislative power to the National Assembly, and judicial power to the judiciary. However, the concentration of extensive powers in the presidency raises valid concerns regarding the preservation of the principle of balance of powers within the constitutional framework. This study aims to elucidate these concerns and provide insights into the potential ramifications for the effective separation and balance of powers within Afghanistan's governance structure. The analysis delves into the mechanisms established by the constitution to ensure the independence and accountability of each branch of government. It examines the interplay between the executive, legislative, and judicial branches, evaluating their respective roles and responsibilities in maintaining the integrity of the constitutional order. Furthermore, the study explores avenues for enhancing the balance of powers and strengthening democratic governance in Afghanistan, considering the evolving political landscape and future prospects for constitutional reform.

Importance of Strange Sea to the Charge Radii and Quadrupole Moment of $J^P=\frac{1}{2}^+,\frac{3}{2}^+$ Baryons

Abstract A statistical framework in conjugation with the principle of detailed balance is employed to examine the low-energy properties, i.e. charge radii and quadrupole moment, of JP = $\frac{1}{2}^+$ octet and JP = $\frac{3}{2}^+$ decuplet baryons. The statistical model relies on the assumption that the baryons can be expanded in terms of quark–gluon Fock states. We systematically apply operator formalism along with the statistical approach to study the charge radii and quadrupole moment of baryons. Based on the probabilities of all possible Fock states in spin, flavor, and color space, the importance of sea with quarks and gluons is studied. The individual contribution of the constituent quarks and sea (scalar, vector, and tensor sea) is explored. Due to the large mass difference between strange and nonstrange content, the SU(3) breaking effect is also investigated. The extent to which strange $q\bar{q}$ pairs are considered in sea is constrained by the mass of hadrons and the free energy of gluons, in accordance with experimental evidence. We focus on the individual contribution of strange and nonstrange sea ($g, \langle u\bar{u}\rangle$, $\langle d\bar{d}\rangle$, and $\langle s\bar{s}\rangle$) accommodability in the respective hadrons for their charge radii and quadrupole moment. The present work has been compared with various theoretical approaches and some known experimental observations. The obtained results may give valuable information for upcoming experimental findings.

Dynamical behaviors, chaotic pattern and multiple optical solitons for coupled stochastic Schrödinger–Hirota system in magneto-optic waveguides with multiplicative white noise via Itô calculus

The primary focus of this study was on exploring the optical soliton solutions and chaotic patterns in magneto-optic waveguides through the coupled stochastic Schrödinger–Hirota equation with multiplicative white noise. Firstly, by means of traveling wave transformations and homogeneous balance principle, the coupled stochastic Schrödinger–Hirota equation in magneto-optic waveguides is transformed into ordinary differential equation. By selecting some suitable parameters, phase diagrams are plotted with the help of the mathematical software Maple. Secondly, the optical soliton solutions of the coupled stochastic Schrödinger–Hirota equation corresponding to phase orbits can be easily deduced through the method of dynamical systems. In addition, chaotic behavior for the coupled stochastic Schrödinger–Hirota system with perturbation term has been discussed in detail. Finally, the two-dimensional and three-dimensional graphs of the stochastic Schrödinger–Hirota equation are drawn, which further explain the propagation of the coupled stochastic Schrödinger–Hirota equation in nonlinear optics.

The Legacy of M.M. Speransky in Modern Financial Law

The article is devoted to the study of the ideas of the famous statesman and public figure of the XIX century M.M. Speransky. His merits in the development of legal science and legal education in Russia are noted, as well as his achievements in the field of financial law are especially emphasized. The project of financial reforms prepared by M.M. Speransky, called the “Finance Plan”, is analysed. The economic situation that caused the financial transformations is considered, and the measures proposed by the great Russian reformer in the field of budget revenues and budget expenditures are examined in detail. The authors note the significant contribution of his idea to the formation of the principles of the budget system of Russia – the principle of budget balance, the principle of efficiency in the use of budget funds, the principles of budget independence and the delimitation of revenues, expenses and sources of financing budget deficits between the budgets of the budget system of the Russian Federation. The classification of budget expenditures proposed by M.M. Speransky for necessary, useful, excessive and excessive (useless) helps to reduce government costs and is very relevant for modern Russia. However, for its legislative consolidation, a clear system of criteria is required. It is also proposed to implement this idea by establishing the category of “priority expenses”, referring to them the so-called necessary expenses to be implemented in any state of affairs. The article indicates significant attention in the works of M.M. Speransky to the issues of proper order and the correct, transparent organization of a particular activity. It is also emphasized the relevance for the modern economy of Russia of its ideas on the reform of budget revenues, their unification, the consolidation of the principle of certainty of taxation and fees. The authors conclude that it is possible to further reform Russian financial legislation through the development of the ideas of M.M. Speransky.

On the Content of the Principle of Balance Public – Private Interests

The article substantiates the interrelation of the non-positivistic legal system based on consideration of the inherent in the law aspiration to justice, with the necessity of highlighting the principle of balance of public and private interests. The results of the main comprehensive scientific research in the fi eld that are based on the consideration of public and private interests balance as a basic legal idea as well as the necessity of its implementation in constitutional and international justice are highlighted. The author concluded that there is constitutional and legal basis for distinguishing the balance of public and private interests as a general legal principle, as well as general approaches to its content in both legal theory and sectoral legal sciences. In order to eliminate the difference in terminology used (balance of interests, ratability, proportionality, balance of constitutional values), it is proposed to use the phrase «balance of public and private interests». In the author’s view, the use of such terminology underlines that the principle under consideration is primarily addressed to the legislator and allows to focus on the objectives for the achievement of which legal regulation is established in certain areas of public relations. Other terms are used mostly in relation to the implementation of this principle in constitutional justice. The dualistic principle to determine the content of the principle of balancing public and private interests is proposed. Firstly, the principle under consideration is about the duty of the legislator and the court to use the necessary and sufficient means to ensure a fair relationship between different interests in establishing legal regulation and resolving disputes. The second approach has instrumental significance and is related to the implementation of this principle within the framework of constitutional proceedings on the basis of proportionality and balance of constitutional values.

An Analytical Method for Timely Predicting of Coal Seam Pressure during Gas Production for Undersaturated Coalbed Methane Reservoirs

Coal seam pressure is an important parameter for production performance evaluation and prediction of coalbed methane (CBM). CBM production from undersaturated CBM reservoirs can be divided into two stages according to critical desorption pressure. At present, few prediction models of coal seam pressure performance consider the comprehensive influence of critical desorption pressure, dissolved gas, matrix shrinkage, and stress sensitivity. For the purpose of accurately predicting coal seam pressure during gas production for an undersaturated coalbed methane reservoir, the material balance principle is used to establish the analytical method for predicting coal seam pressure, considering the comprehensive influence of the critical desorption pressure, dissolved gas, matrix shrinkage, and stress sensitivity. Then, the proposed method is verified against a numerical simulation case using a computer modelling group (CMG) and two actual coalbed methane wells. Finally, the sensitivities of influencing factors on the coal seam pressure are analyzed. The results show that good agreements were obtained between the calculated coal seam pressures using the proposed method and those from the CMG-GEM simulation case and actual CBM wells, with the relative errors all being less than 1%. When ignoring the influence of critical desorption pressure and mistaking pd for pi as well as ignoring Cs, the relative error can reach as high as 31.3%. The main factors affecting the coal seam pressure are the critical desorption pressure and free gas saturation. The proposed method is simple to use, and without shutting-in the well, it can provide an important basis for production performance evaluation and development strategies.

Nonlinear control of electro‐hydraulic screw conveyor system for shield machine based on disturbance observer and back‐stepping method

AbstractIn order to improve the precision of earth pressure balance control and anti‐interference ability of shield sealing chamber, this paper proposes a nonlinear control strategy for the screw conveyor based on disturbance observer and back‐stepping method, so as to ensure the safe and efficient tunneling of the shield machine. According to the hydraulic flow dynamic balance principle of shield machine, the mechanism model of electro‐hydraulic screw conveyor system is established, and the system state space model is derived. The nonlinear controller of the screw conveyor is designed by using the inverse step method and the disturbance observer compensation characteristic, so that the system responds quickly and compensates for the flow disturbance and external force disturbance in real time. At last, the system stability is proven by using the Lyapunov function. The experimental results show that the method has high control accuracy with fast response and strong anti‐interference ability.

Distributed optimal Volt/Var control in power electronics dominated AC/DC hybrid distribution network

AbstractThe integration of large‐scale distributed power sources increases the voltage fluctuation in AC/DC hybrid distribution network (AD‐HDN). Power electronics devices such as photovoltaic (PV) inverters, soft open point (SOP), and voltage source converters (VSCs) can be utilized for voltage/var control (VVC) to alleviate the risk of voltage fluctuation and violation. This paper proposes a distributed optimal VVC method in power electronics dominated AD‐HDN. Firstly, the reactive power and voltage characteristics of PV inverters, SOP, and VSCs are analysed, and an optimal VVC optimization model for AD‐HDN to minimize node voltage deviation, PV curtailment, and network loss is proposed. Then, the second‐order cone (SOC) relaxation technique is used to re‐formulate the model into a convex optimization model. A distributed optimal VVC framework based on the alternating direction method of multipliers (ADMM) is constructed. Based on the residual balance principle and relaxation technique, an accelerated ADMM method is further proposed to solve the proposed model. Finally, case studies are conducted on the IEEE 33‐node and 85‐node systems to verify the superiority and effectiveness of the proposed method.

OVERVIEW OF THE PRINCIPLES OF THE MODERN ACCOUNTING SYSTEM AND FINANCIAL REPORTING IN UKRAINE

The article examines and defines the areas of application of the accounting and financial reporting principles that are widespread in the accounting practice of Ukrainian enterprises. The authors have studied their classification according to various characteristics, the emergence of the need and possibilities of their approximation, and the harmonisation of national standards. We analyse the appropriateness of using the principles for types of the accounting necessary to reflect the facts of economic functioning, observed phenomena, and processes. The article considers the peculiarities of the functioning of the modern accounting system and financial reporting of Ukraine according to the principles of autonomy, continuity, and matching of income and expenses and examples of their use in modern enterprises of Ukraine. Per the principles of the predominance of substance over form and a single monetary measure, the historical (actual) value is considered a base indicator. The principles of periodicity, consistency, and full disclosure are a prerequisite for the emergence of the principle of prudence (when receiving doubtful debts). Therefore, when evaluating the information provided in the reports, one should not overstate assets and income or understate expenses and liabilities. The principle of balance between monetary and non-monetary indicators indicates the need to use a complex of different indicators when displaying the accounting object of separate levels of management and various forms of reporting, thus forming an array of relevant information. The study’s results consider principles as the core initial provisions of accounting, the basic concept that is the basis of assessment and recognition in accounting processes, and disclosure of the economic activity results in financial statements. The principle of timeliness should be considered the main accounting principle. We propose to add the principles of representativeness, impartiality, and comparability to the existing principles. Keywords: accounting, business operations, accounting system principles, accounting system, financial reporting.
