A fuzzy semi-analytical approach for modeling uncertainties in solitary wave solution of coupled nonlinear Boussinesq equations
Authors: Vana Rambabu , Karunakar Perumandla 
Published: August 2024

Abstract
This article presents the precise solitary wave solution (SWS) of nonlinear coupled Boussinesq equations (BEs) in shallow water using the Homotopy Perturbation Transform Method (HPTM) and Fuzzy HPTM (FHPTM). The study introduces a fuzzy model for the coupled BEs by incorporating uncertainties in wave depth coefficients. The effectiveness of FHPTM is demonstrated through a comparison with the exact solution for the crisp case, using the double parametric approach to highlight the fuzziness in the solution. Numerical results under various scenarios are examined to understand the behavior of the SWS. HPTM results are compared with those derived from the Adomian Decomposition Method (ADM). The results show good agreement with both exact and numerical techniques.
Existence and multiplicity of solutions for singular differential equations with non-local boundary conditions*
Authors: Wei Yongfang 
Published: August 2024

Abstract
This paper focuses on the investigation of a class of singular differential systems with non-local boundary conditions. Its primary objective is to establish the variational structure of the non-local singular differential systems, and systematically explore multiple solutions through the application of the variational method. A significant achievement of this research is the demonstration that the energy functional satisfies the Cerami condition within an appropriate Sobolev's space. The derivation of key results is facilitated by the strategic application of the Minimization sequence and Fountain Theorem. Furthermore, even in cases where the nonlinear term fails to meet the Ambrosetti-Rabinowitz condition, this paper successfully applies the variational method to address the associated problems. The challenges addressed in this study include proving the convergence of the solution sequence, ensuring the continuous differentiability of the energy functional, and showcasing the embedding property of space. Distinguishing itself from existing research, this paper innovatively constructs a variational framework tailored specifically for singular differential systems with non-local boundary conditions. The utilization of variational methods enables a meticulous and systematic exploration into the solvability of these intricate problems.
Nonlocal FG porous adsorber with 2D PSH network under magnetic intensity for large frequency range considering vdW interaction potentials
Authors: Khouni Soumia , Bourouina Hicham 
Published: August 2024

Abstract
In this contribution, the nonlocal frequency shift is investigated and analyzed for an adatoms-microstructure system, considering the effects of nonlocal behavior, adatom distribution, and magnetic field. The microstructure is a sandwich microbeam including face sheets that are functionally graded porous (FGP) and a longitudinally perforated core with a uniform periodic square hole’s network (PSH) arranged parallel to the length of the sandwich microbeam. The material characteristics for three layers are assumed to change along the thickness correspondingly to a power law function, where Maxwell’s equations are exploited to express how the applied magnetic field has been affected. Eringen’s nonlocal elasticity is utilized to incorporate small-scale behavior. At the same time, van der Waals interactions between the adatom itself and the adatom microstructure substrate are established employing Lennard-Jones (6–12) and Morse potentials to account for the energy induced by adsorption. The dynamic equations of vibration are modified to develop the Euler–Bernoulli beam model (EBM) and Levinson beam model (LBM), which are then solved using Navier solution method (NSM) and differential quadrature method (DQM) to determine the resonance shift. Numerical results revealed that the calculated shift response was influenced by the perforation characteristics, adsorbed adatoms, magnetic field intensity, and small-scale behavior. Consequently, numerical results are discussed to investigate the nonlocal dynamic response of adatom-microstructure systems, which are relevant to developing mass sensing devices incorporated into micro/nanoelectromechanical systems (M/NEMS).
Numerical investigation of fractional order chaotic systems using a new modified Runge-Kutta method
Authors: Sai Lekshmi A , Balakumar V 
Published: August 2024

Abstract
This article introduces a new modified two-stage fractional Runge-Kutta method for solving fractional order dynamical systems. The non-integer order derivative is considered in the Caputo sense, as it reliably captures the physical nature of the systems. A comprehensive mathematical analysis is performed, covering aspects such as consistency, convergence and error bound. The method’s effectiveness is validated by comparing it with existing methods in the literature for solving linear and nonlinear fractional initial value problems. The proposed method is then utilized to investigate a wide range of commensurate fractional order continuous systems demonstrating chaotic behavior, with their phase diagrams illustrated. Parametric configurations and fractional orders for which specific fractional attractors either exhibit or lack chaotic behavior is also examined. The computation Lyapunov exponents and 0-1 test have been performed to elucidate the dynamic behaviors of the analyzed fractional order systems.

Abstract
The extraordinary crystal structure and tunable characteristics of A-site double perovskite oxides make them noteworthy as A-site cations can be precisely tailored to control their chemical and physical properties, opening up new possibilities for high-performing materials in particular technological applications. This manuscript examines the analysis of the physical traits of SrMInSbO6 (M = Hf, Ca) using the DFT technique. Birch-Murnaghan equation is implemented to optimize crystal structures. Both structures are structurally, thermodynamically, and mechanically stable as predicted by a tolerance factor, negative formation energies and elastic constants. Electronic band structures reveal semiconducting behavior with bandgap of 0.87 eV and 0.93 eV for SrHfInSbO6 and 1.17 eV and 3.11 eV for SrCaInSbO6 using GGA and mBJ, respectively. Total and partial DOS plots also emulate electronic band structure profiles perfectly. Furthermore, the optical characteristics for SrMInSbO6 (M = Hf, Ca) revealed strong absorption along with optical conductivity and lowest energy loss in the visible and UV region. The computed characteristics expose the potential of investigated perovskites for water splitting and optoelectronics.

Published: August 2024

Abstract
The paper investigated a set of non-Gaussian states generated by measuring the number of particles in one of the modes of a two-mode entangled Gaussian state. It was demonstrated that all generated states depend on two types of parameters: some parameters are responsible for Gaussian characteristics, while other parameters are responsible for non-Gaussian characteristics. Among all generated states, we identified those optimally generated in terms of the generation probability and the magnitude of non-Gaussianity.
Study on differential magnetic fields of nuclear magnetic resonance gyroscope
Authors: Zhang Hao , Yue Yazhou , Lei Xing , Huang Chenyu 
Published: August 2024

Abstract
During the operation of NMRG, polarized alkali atoms will produce a magnetic field. Different noble gases feel different magnetic fields produced by polarized alkali atoms magnetic field, which will lead to extra bias drift of gyroscope output. Countering this phenomenon, the influence of differential magnetic field on gyroscope output is analyzed theoretically, and the method of calculating differential magnetic field is optimized. The effects of static magnetic field, working temperature, and different cell insufflation parameters on differential magnetic field are studied experimentally. The result shows that the static magnetic field intensity has no obvious effect on the differential magnetic field. There is a working temperature point that makes the differential magnetic field zero when the relaxation time of the two noble gases is the same, and the cell insufflation parameters influence the differential field by influencing the difference in relaxation time.

Investigation on the transient aerodynamics of a tube-launched unmanned aerial vehicle with a span-extended wing
Authors: Si Peng , Wu Mingjian , Huo Yongqing , Wu Zhilin 
Published: August 2024

Abstract
Span morphing wings are designed for unmanned aerial vehicles to improve aerodynamics and flight performance. The aerodynamic analysis mainly focuses on the quasi-steady performance of span-morphing wings under several typical configurations. However, the aerodynamic characteristics become unsteady and dynamic during the morphing process. This work, therefore, performs a numerical study on the transient performance and the mechanism of a tube-launched aircraft with a span-extended wing. The numerical results show that the transient aerodynamic force creates a dynamic hysteresis loop surrounding the quasi-steady data. The relative deviation in the drag is larger than in the lift, and the hysteresis effect of the flow field is the major contributor. It changes the force distribution by affecting the formation of the wingtip vortex. This work can provide a reference to the design of tube-launched UAVs.

Published: August 2024

Abstract
Surface pressure measurement is an important part of aerodynamic research. In this study, a novel pressure measurement system based on Micro-Electro Mechanical System (MEMS) pressure sensors was designed and fabricated. The selected integrated silicon piezoresistive sensors are characterized by small size, low cost, high accuracy, and easy integration. Multi-channel simultaneous measurement of surface pressure is realized by integrating multiple sensors in a self-designed printed circuit board (PCB). A U-shape tube differential pressure device was used to calibrate the constructed pressure measurement system and the measured results are compared with those of commercial sensors. It is shown that the MEMS sensor output had good accuracy and linearity. The pressure measurement system was used to measure the pressure on the surface of a circular cylinder and a NACA0015 airfoil in a wind tunnel. The results further verified the feasibility and reliability of the present measurement system. Compared with other pressure measurement methods, the surface pressure measurement method based on MEMS sensors developed in this paper greatly reduces the cost, and at the same time has good customizability, which can effectively expand the application scenarios and scope of the pressure measurement technique.
Simulation analysis of mud and sand separation performance of hydrocyclone based on fluent
Authors: Wu Juefan , Lin Jiming 
Published: August 2024

Abstract
The hydrocyclone exhibits a simple structure yet harbors a highly intricate internal flow field, necessitating precise structural parameters and accuracy. This study commences by employing SolidWorks for three-dimensional modeling of the hydrocyclone, followed by integrating the CFD numerical simulation method and utilizing Fluent to simulate the sediment separation process within the cyclone. The investigation delves into analyzing the impact of the flow field within the hydrocyclone and the operational parameters on its separation efficiency. The findings reveal that appropriately increasing the feed concentration can mitigate underflow entrainment and enhance the quality of underflow products to a certain extent, whereas increasing the feed mud content yields contrary results. The outcomes of this research offer theoretical guidance for the deployment of similar hydrocyclones in field applications.
The Rhetoric of Falseness or, How to Talk about a Discord
Authors: Chan Eleanor 
Published: August 2024

Abstract
The role of dissonance in harmony is a well-established musicological fact but has rarely been explored in a broader disciplinary context, where the metaphor of harmony is applied to objects beyond the musical. This chapter seeks to address this relative absence by problematizing the phrase ‘sweet music’ as a descriptor of pleasant musical experience. It investigates possible routes towards understanding the murkier corners of understanding of the false relation and understanding of discord in general by entertaining metaphor and the power of suggestion as a tool of musicological analysis, and the importance of the evocative trace as evidence alongside the concrete, documented connection. It investigates the literature of the period, both explicitly and implicitly musical to shine a light on the lexicon of falseness through its unexpected synonym, ‘sweet’, and the developing imagery and attitudes surrounding sugar, as England began to import it in ever greater quantities.
Practical Reason as the Source of Explanation and Comprehension
Authors: Zinkin Melissa 
Published: August 2024

Abstract
This chapter sets the stage for a discussion of practical reason in the Groundwork by arguing that practical reason can be a faculty for explanation and comprehension rather than for justification. Typically, the justification of an action is what gives me a reason to act and the explanation is what gets me to comprehend why the action occurs. However, explanations can also be practical; an explanation for why I ought to perform some action can motivate me to do it. It is then possible that the reason why I ought to perform some action is a reason that I comprehend, and comprehend deeply, rather than simply a reason that I endorse, as in Christine Korsgaard’s account. This occurs when I comprehend that my own end is to be an end in myself.
Shallow Morality in the Groundwork
Authors: Zinkin Melissa 
Published: August 2024

Abstract
This chapter begins the book’s interpretation of the Groundwork with a discussion of common moral rational cognition (CMRC) in Groundwork I. Although CMRC determines its actions by asking itself “can you also will that your maxim become a universal law?” it still has a propensity to rationalize against the strict laws of duty. What, then, is missing from CMRC? CMRC is shallow because even though it only acts on maxims that can be a universal law, it fails to comprehend why it is obligated to act on such maxims. It ought to act on maxims that can be a universal law because to do so is to act for the sake of its own rational nature. Only by grasping this reason are we deeply motivated to do what is right and our conformity to the moral law is not precarious.
Introduction

Published: August 2024

Abstract
The relationship between humans and civil wars has profound implications for our comprehension of violence and its impact on modern society. Civil wars have humanitarian consequences and inflict immense suffering. In our interconnected world as civil wars cross national borders, escalate, and encourage foreign intervention they have far-reaching consequences for global peace, justice, and prosperity. These interconnections—the variation in their causes, how they are fought, how they evolve, and how they end—therefore remains vital.
Origins and ambitions
Authors: Clark Heather 
Published: August 2024

Abstract
This chapter provides an overview of Sylvia Plath’s origins and ambitions. Plath was born in Boston, Massachusetts in the early days of the Great Depression. The chapter then details Plath’s early poems and two semi-autobiographical stories told from the perspective of a girl growing up in greater Boston during the war who is bullied by neighborhood children on account of her Germanic heritage. Plath entered Smith College, a renowned all-women’s college in western Massachusetts. The poems she wrote there display a preoccupation with form and sound, sometimes at the expense of meaning. Eventually, Plath would embrace free verse and looser lines after she married Ted Hughes, but she never abandoned poetic structure entirely.
Hypothesis tests in ordinal predictive models with optimal accuracy
Authors: Liu Yuyang , Luo Shan , Li Jialiang 
Published: August 2024

ABSTRACT
In real-world applications involving multi-class ordinal discrimination, a common approach is to aggregate multiple predictive variables into a linear combination, aiming to develop a classifier with high prediction accuracy. Assessment of such multi-class classifiers often utilizes the hypervolume under ROC manifolds (HUM). When dealing with a substantial pool of potential predictors and achieving optimal HUM, it becomes imperative to conduct appropriate statistical inference. However, prevalent methodologies in existing literature are computationally expensive. We propose to use the jackknife empirical likelihood method to address this issue. The Wilks’ theorem under moderate conditions is established and the power analysis under the Pitman alternative is provided. We also introduce a novel network-based rapid computation algorithm specifically designed for computing a general multi-sample $U$-statistic in our test procedure. To compare our approach against existing approaches, we conduct extensive simulations. Results demonstrate the superior performance of our method in terms of test size, power, and implementation time. Furthermore, we apply our method to analyze a real medical dataset and obtain some new findings.
Supervisor synthesis for opacity enforcement in partially observed discrete event systems
Authors: Xie Huawei , Liu Jing , Li Na 
Published: August 2024

Abstract
Opacity is an important system property that is particularly relevant in the context of system security and privacy. A system is considered opaque if the predefined secret behavior of the system is not leaked to an external intruder. In this work, the opacity property is studied in the framework of labeled Petri nets (LPNs). The secret in an LPN system is characterized by a subset of reachable markings. Firstly, an opacity basis reachability graph (OBRG) containing opacity information of the system is developed to denote a system’s reachability set without computing all reachable states. Then the observer of the OBRG is computed, based on which a necessary and sufficient condition is derived to verify the opacity of the LPN system. Finally, given an LPN that does not satisfy the opacity, a maximally permissive supervisor is introduced to guarantee that the controlled system is opaque.
Design and optimization of electricity market trading mechanism based on blockchain technology

Published: August 2024

Abstract
An increasing number of distributed energy resources, acting as Supplier nodes, are participating in electricity market transactions. In order to meet the demand for large-scale renewable energy participation in the market, this article proposes a multi-layered electricity trading framework based on blockchain technology. This framework, with consortium chain technology at its core, is divided into network layer, regulatory layer, and physical layer. The feasibility of the proposed electricity trading model has been verified through simulation. Furthermore, this study divides the electricity trading process into stages, adopting noncooperative game theory for the bidding and clearing stages of trading nodes. After listing the remaining untraded nodes following the cycle auction, the node electricity price eventually converges to around 0.7 yuan/kW·h in the simulation game. By solving the game, rational node matching is achieved, while also matching untraded nodes with trading partners. The established electricity trading model in this article aims to provide trading services to nodes under different trading scenarios as much as possible, thereby enhancing the utilization of distributed energy resources. Future work will focus on refining the blockchain technology used in our framework, particularly exploring optimizations for scalability and efficiency in handling a larger volume of transactions involving distributed energy resources.

Abstract
The distribution of chlorophylls in eggplant (Solanum melongena) peel exhibits either a uniform pattern or an irregular green netting pattern. The latter, manifested as a gradient of dark green netting that is intensified in the proximal part of the fruit on a pale green background, is common in wild relatives and some eggplant landraces. Despite the selection of uniform chlorophylls during domestication, the netting pattern contributes to a greater diversity of fruit colours. Here, we used over 2300 individuals from different populations, including a multi-parent advanced generation inter-cross population for candidate genomic region identification, an F2 population for bulked segregant analysis by sequencing, and advanced backcrosses for edges-to-core fine-mapping, to identify SmGLK2 gene as responsible for the irregular netting in eggplant fruits. We also analysed the gene sequence of 178 S. melongena accessions and 22 wild relative species for tracing the evolutionary changes that the gene has undergone during domestication. Three different mutations were identified leading to the absence of netting. The main causative indel induces a premature stop codon disrupting the protein conformation and function, which was confirmed by western blot analysis and confocal microscopy observations. SmGLK2 has a major role in regulating chlorophyll biosynthesis in eggplant fruit peel.
