Summary: This study analyzes the time-fractional coupled Burger's model and obtains various solitary wave solutions using a modified exp-function approach. The results demonstrate that the fractional parameters have a significant impact on wave propagation, with higher values leading to increased wave structure. In the case of a two-wave solution, an increase in the time-fractional parameter results in increased wave structure for both u- and v-components. The proposed computational code offers consistent advantages, including exact solutions, reduced computational complexity, stability, and efficiency.

Summary: The paper introduces a multi-scale model to investigate the interactions between within-host kinetics and between-host transmission. A mean-field communicable disease model on complex networks is proposed to link the within-host and between-host systems. The stability of each feasible equilibrium for the multi-scale epidemic model is rigorously established. Numerical simulations reveal that the between-host system's basic reproduction number (RB0) is positively correlated with the within-host system's basic reproduction number (RT0), and the final epidemic size increases with RB0. The study also highlights the significant role of network topology in infection transmission patterns.

Summary: This article aims to construct a mathematical model of two-step reversible chemical reactions using a Caputo fractional difference operator. The reaction involves the breakdown of an ester compound in the presence of water and the formation of fatty acid salts from the reaction of a free fatty acid with alkali hydroxide. The chaotic response of the system is illustrated using bifurcation diagrams and the synchronization of the subsystems is achieved with nonlinear control functions.

Summary: According to the inflationary theory of cosmology, the majority of elementary particles in the current universe were formed during the reheating phase after inflation. This study self-consistently couples the Einstein-inflaton equations with a strongly coupled quantum field theory, described by holography, and demonstrates the resulting inflation, reheating, and a universe dominated by the quantum field theory in thermal equilibrium.

Summary: A series of novel E, E/E, Z isomers based on 5-(2-cyano-3-ethoxy-3-oxoprop-1-en-1-yl)-1H-pyrrol-2-yl acrylic acid were synthesized, and their emission and temperature effects were compared. The different isomers exhibited varied luminous colors and aggregation-induced emission (AIE) properties. The E, E-OC2H5COOH loaded on filter paper could identify alkaline compounds, and the E, E-OC2H5COOH strips could selectively discriminate for n-/sec-/tert-butylamine by changing the fluorescence color. The configuration of double bonds could regulate fluorescence change and improve material properties.

Summary: In this study, a coupled gas diffusion and heat conduction model was developed to investigate the dynamical process of heat and mass transfer in coal matrix. The results revealed that heat transfer significantly influences gas desorption behavior, and the thermal boundary conditions affect the temperature and concentration distributions. The coupled model provides a more accurate description of gas desorption compared to the uncoupled diffusion model.

Summary: The recently released data on differential cross sections for & gamma;n -K0E0 and & gamma;n -K+E- reactions from the A2 and BGOOD Collaborations were analyzed. The theoretical model proposed in previous work was found to qualitatively reproduce the A2 data but failed to describe the BGOOD data accurately. Further analysis showed that resonances N(1710)1/2+, N(1900)3/2+, and A(1910)1/2+ dominate the reactions in the lower energy region. The t-channel K*(892) exchange plays a crucial role at forward angles in the higher energy region.

Summary: An axiomatic approach for channel divergences and channel relative entropies based on three information-theoretic axioms is introduced, showing that these axioms are sufficient to give enough structure in the channel domain. The amortized channel extension of the Umegaki relative entropy is proven to be optimal for quantum channels, providing a lower bound on all channel relative entropies.

Summary: Under oscillatory shear, a monolayer of frictional granular disks undergoes two dynamical phase transitions: a transition from an initially disordered state to an ordered crystalline state, and a dynamic active-absorbing phase transition. Surprisingly, these transitions occur at the same critical point and can also be characterized by nontrivial disk trajectories breaking time-reversal invariance.

Summary: Synthetic anion transmembrane transporters offer a new approach for treating channelopathies by replacing defective ion channels. However, the availability of suitable candidates is limited due to associated toxicity. In this study, we report 3-(1H-1,2,3-triazol-1-yl)benzamides as non-toxic transmembrane anion carriers, showing selective and electrogenic chloride transport activity.

Summary: This paper investigates the problems of dynamical multisynchronization (DMS) and static multisynchronization (SMS) for a class of delayed coupled multistable memristive neural networks (DCMMNNs) using a novel hybrid controller. The controller combines delayed impulsive control and state feedback control to ensure synchronization, with new linear matrix inequalities (LMIs)-based conditions proposed. Numerical examples demonstrate the effectiveness of the proposed method for DMS and SMS of DCMMNNs.

Summary: A novel oxidative (3 + 3) cycloaddition/ring-opening reaction has been developed between N,N'-cyclic azomethine imines and in situ generated diaza-oxylallyl cations from simple urea derivatives in the presence of base and PhI(OAc)(2). This transformation shows good performance with a broad substrate scope, providing easy and rapid access to 1,2,3,5-tetrazine-4(1H)-one derivatives in good yields.

Summary: In this study, supervised machine learning of few interacting bosons in optical speckle disorder was conducted via artificial neural networks, revealing an approximately universal power-law scaling in the learning curve. A network architecture was introduced to train and test on heterogeneous datasets, providing accurate predictions for different system sizes and allowing extrapolations to larger sizes. Notably, a novel transfer-learning strategy was implemented to accelerate and accurately model larger systems by including small-size instances in the training set.

Summary: We propose a mechanism for liquid formation in strongly correlated lattice systems by studying dipolar bosons in one-dimensional optical lattices as an example. We present a perturbative theory and validate it through simulations for the energetic and structural properties of the system's phases. We analyze the nonequilibrium properties and calculate the dynamic structure factor.

Summary: In this study, we investigate the interaction of one-dimensional bosons in the universal low-energy regime. The combination of attractive and repulsive interactions stabilizes quantum gases, droplets, and liquids. We focus on the role of effective three-body repulsion in systems with weak attractive pairwise interactions and show that at low densities in the gas phase, the equations of state in both theories agree quantitatively for overall repulsion. However, this agreement is absent in the attractive regime, where universality only occurs in the long-distance properties of quantum droplets.

Summary: This article describes a procedure to improve direct diagonalization results for few-particle systems trapped in one-dimensional harmonic potentials with contact interactions. The procedure starts with the two-body problem and defines a renormalization method for the interparticle interactions. The benchmarking of the procedure is done with state-of-the-art numerical results for three and four symmetric fermions.

Summary: The study focuses on weakly repulsive Bose-Bose mixtures in two and three dimensions at zero temperature using the functional renormalization group (FRG). It examines the RG flows, the role of density and spin fluctuations, conditions for phase separation, and compares FRG calculations favorably with known results from perturbative approaches for macroscopic properties.
