Summary: This study investigated three alternative ensembles for estimating network reliability, concluding that random walks on structure function failed in highly reliable networks, while other methods performed efficiently for certain network types. The 1/t algorithm using random walks on probability space was the only ensemble that yielded accurate estimates for a dodecahedron network, but still failed at the highest level of network reliability. Further investigation is needed for methods that can reduce variance for large, highly reliable networks.

Summary: Kirkwood-Buff integrals (KBIs) serve as a powerful tool linking atomic scale structuring accessed by simulations with thermodynamics, bridging the gap between microscopic and macroscopic quantities. This study presents simulation research on the concentration dependence of KBIs for various binary ethanol mixtures, demonstrating that the best approach to KBI calculation varies depending on the structural complexity of the simulated system.

Summary: The study demonstrates the convergence of solutions to non-Markovian hyperbolic equations to the solution of the nonlinear kinetic Landau equation while preserving the full singularity of the Landau kernel. It resolves the transition from microscopic reversible dynamics to macroscopic irreversible equations, highlighting the intrinsic physical property of singularity in the Landau equation due to the geometry of particle interactions.

Summary: In this work, we developed an implementation of the Wang-Landau algorithm to find the density of states (DOS) in a given system. The implementation, using Python and C++ languages, takes advantage of libraries for energy computation and considers code parallelization for faster computation. The effectiveness and accuracy of the implementation were demonstrated through studies on various systems, providing a powerful and flexible tool for studying realistic matter models.

Summary: The synthesis of SmBa2Cu3O7-delta superconducting material by standard solid-state reaction is reported, with DC resistivity measurements and fluctuation analysis performed. Results show that the properties of this material largely agree with experimental reports for RBa2Cu3O7-delta and YBa2Cu3O7-delta superconductors.

Summary: Raman spectra contain rich substance information and unique fingerprint characteristics. However, accurately identifying them is challenging due to the variety of substances and complex characteristic information. This study proposes a comprehensive evaluation method based on multidimensional constraint, which extracts and recognizes spectral characteristics, analyzes them from local and global perspectives, and achieves high automatic recognition rates even for spectra from instruments with low technical specifications.

Summary: The study validated the ESC NSTEMI guidelines for the observe-zone of the 0/1h hs-cTnT algorithm and proposed new 0/3h criteria, which can more accurately rule out or rule in NSTEMI by measuring hs-cTnT concentrations and changes.

Summary: In this study, a Modified Artificial Bee Colony algorithm (MABC) is proposed to solve the multiple-choice multidimensional knapsack problem (MMKP). The MABC algorithm employs surrogate relaxation, Hamming distance, and a tabu list to enhance the local search process and exploit neighborhood information. Experimental results show that the MABC algorithm produces highly competitive solutions in terms of the best solutions found and demonstrates improved CPU efficiency compared to other state-of-the-art algorithms.

Summary: In this paper, a new generating function is constructed and used to establish a fourth-order numerical differential formula for approximating the Riesz derivative with order gamma is an element of (1, 2]. The formula is then applied to study the two-dimensional nonlinear spatial fractional complex Ginzburg-Landau equation and a convergence order of O(tau 2 + h4x + h4) is obtained. The unique solvability, unconditional stability, and convergence of the numerical algorithm are proved using discrete energy method and newly derived discrete fractional Sobolev embedding inequalities. Numerical results confirm the theoretical correctness and effectiveness of the proposed scheme. (c) 2023 Elsevier B.V. All rights reserved.

Summary: This study focuses on the strong convergence of certain multidimensional continued fraction algorithms, proving that the second Lyapunov exponent of Selmer's algorithm is negative in two and three dimensions. Heuristic results are given on several other continued fraction algorithms. The results suggest that all classical multidimensional continued fraction algorithms lose strong convergence in high dimensions, with the exception of the ArnouxRauzy algorithm which is defined on a measure zero set.
