A Variational Beam Model for Failure of Cellular and Truss‐Based Architected Materials
Advanced Engineering Materials, EarlyView., 2023 Herein, a versatile and efficient beam modeling framework is developed to predict the nonlinear response and failure of cellular, truss‐based, and woven architected materials. It enables the exploration of their design space and the optimization of their mechanical behavior in the nonlinear regime. A variational formulation of a beam model is presented

Architected Lattices with a Topological Transition
Advanced Engineering Materials, EarlyView., 2023 This article develops topological metamaterials showing multidirectional two‐step deformation under compression by embedding contact‐enabled topological mechanisms into lattice structures. Experiments on 3D‐printed 2D and 3D lattices and finite element simulations are conducted to demonstrate the working principle of the topological metamaterials.

Monotone matrices and monotone Markov processes
Stochastic Processes and their Applications, 1977 AbstractA stochastic matrix is “monotone” [4] if its row-vectors are stochastically increasing. Closure properties, characterizations and the availability of a second maximal eigenvalue are developed. Such monotonicity is present in a variety of processes in discrete and continous time. In particular, birth-death processes are monotone.

Monotonic and dual monotonic language learning
Theoretical Computer Science, 1996 AbstractMonotonic and dual monotonic language learning from positive as well as from positive and negative examples is investigated. Three different notions of monotonicity are considered. Each of them reflects an alternative formalization of the requirement that the learner has to produce better and better generalizations when fed more and more data ...

Monotone Strategyproofness [PDF]
SSRN Electronic Journal, 2013 We propose a way to compare the extent of preference misrepresentation between two strategies. We define a mechanism to be monotone strategyproof when declaring a "more truthful" preference ordering in the mechanism dominates - with respect to the true preferences - declaring a less truthful preference ordering.

Journal of Differential Equations, 1979 This is a study of systems which possess several steady states and whose solutions approach the set of the steady states as time tends to infinity. One is especially interested in the property of mutability, which implies the ability of the system to execute transitions from one steady state to another.

Curve-based monotonicity: a generalization of directional monotonicity [PDF]
International Journal of General Systems, 2019 In this work we propose a generalization of the notion of directional monotonicity. Instead of considering increasingness or decreasingness along rays, we allow more general paths defined by curves in the n-dimensional space. These considerations lead us to the notion of α-monotonicity, where α is the corresponding curve.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Due to the tight curvature in their design, ring applicators are usually associated with large positioning errors. The standard practice to correct for these deviations based on global offsets may not be sufficient to comply with the recommended tolerance.
