Abstract:
In this work, temperature-dependent in situ x-ray diffraction reciprocal space mappings are employed to reveal three-dimensional lattice shear deformation in epitaxial VO2 variants, and linear Lagrangian strain tensors of epitaxial lattices are deduced by metric tensors of the reciprocal space at various temperatures. An equilibrium modulated-monoclinic phase is identified above the critical temperature, which is permitted in a translationengleiche subgroup from high symmetry with an index of 4. Being different from the conventional low-temperature monoclinic phase, the high-temperature monocl

Abstract:
Role-based access control (RBAC) is a widely adopted security model that provides a flexible and scalable approach for managing permissions in various domains. One of the critical challenges in RBAC is the efficient assignment of roles to users while minimizing the number of roles involved. This article presents a novel role minimization optimization algorithm (RMOA) based on the concept lattice factor to address this challenge. The proposed RMOA leverages the concept lattice, a mathematical structure derived from formal concept analysis, to model and analyze the relationships between roles, p

Abstract:
We introduce a novel type system for enforcing secure information flow in an imperative language. Our work is motivated by the problem of statically checking potential information leakage in Android applications. To this end, we design a lightweight type system featuring Android permission model, where the permissions are statically assigned to applications and are used to enforce access control in the applications. We take inspiration from a type system by Banerjee and Naumann to allow security types to be dependent on the permissions of the applications. A novel feature of our type system is

Abstract:
Access control policies are programs used to secure cloud resources. These polices should only grant the necessary permissions that a given application needs. However, it is challenging to write and maintain policies as applications and their required permissions change over time. In this paper, we focus on the Amazon Web Services (AWS) IAM policy language and present an approach that, given a policy, synthesizes a modified policy that is more restrictive and better abides to the principle of least privilege. Our approach looks at the actual access history (e.g., access logs) used by an applic

Abstract:
The problem of role engineering is extended by the subproblem of permissions engineering. It is assumed that discretionary access control is specified in the information system. To build a role-based security policy, a technique based on algorithms for formal concept analysis is proposed. Based on the access matrix, a Galois lattice is constructed, the nodes of which are interpreted as possible permissions. Criteria for choosing the optimal set of permissions are determined and a heuristic algorithm for solving the problem is discussed.

Abstract:
Applying chameleon hash functions to redactable blockchains is still challenging work. Most redactable blockchain solutions using this technique have potential problems, such as too weak decentralization performance and trapdoors with exposure risks. In addition, quantum computing also threatens the security of blockchain systems. The above two issues imply that the development of redactable blockchains is still constrained, and that quantum-resistance will be requirements for blockchain applications. Therefore, we constructed a chameleon hash function over lattices while utilizing a hierarchi

Abstract:
Flapping, flexible insect wings deform under inertial and fluid loading. Deformation influences aerodynamic force generation and sensorimotor control, and is thus important to insect flight mechanics. Conventional flapping wing fluid–structure interaction models provide detailed information about wing deformation and the surrounding flow structure, but are impractical in parameter studies due to their considerable computational demands. Here, we develop two quasi three-dimensional reduced-order models (ROMs) capable of describing the propulsive forces/moments and deformation profiles of flexib

Abstract:
The steady state properties of the mean density population of infected cells in a viral spread is simulated by a general forest like cellular automaton model with two distinct populations of cells (permissive and resistant ones) and studied in the framework of the mean field approximation. Stochastic dynamical ingredients are introduced into this model to mimic cells regeneration (with probability p) and to consider infection processes by other means than contiguity (with probability f). Simulations are carried out on a L×L square lattice taking into consideration the eighth first neighbors. T
