A theory of linear inequality systems

open access: yesLinear Algebra and its Applications, 1988
AbstractThis paper provides results on the boundedness, the dimension, the boundary, and the relative boundary of the feasible set of (possibly infinite) linear inequality systems defined on a finite dimensional space. It analyzes the redundancy, the minimality, and the finite reduction of such systems, as well as the relation between any system and ...

Observation of Optical Precursor in Time‐Energy‐Entangled W Triphotons

open access: yesAdvanced Science, EarlyView.
This study reports the observation of optical precursors at the triphoton level through the SSWM process. By appropriately adjusting the optical depth (OD), optical precursors are effectively separated from the main wave through utilizing the slow‐light effect to manipulate the triphoton temporal correlations in the group delay regime.

Robust Control Theory for Time Lag System in Chemical Engineering and Its Application

open access: yesChemical Engineering Transactions, 2017
A series of problems of the time-lag system including robust stability analysis and guaranteed cost controller design are studied mainly based on the Lyapunov stability theory by linear matrix inequality method and time lag partitioning method in this ...

On separability of quantum states and the violation of Bell-type inequalities

open access: yes, 2003
In contrast to the wide-spread opinion that any separable quantum state satisfies every classical probabilistic constraint, we present a simple example where a separable quantum state does not satisfy the original Bell inequality although the latter ...

l1 solution of linear inequalities [PDF]

open access: yesIMA Journal of Numerical Analysis, 1999
The numerical solution of a possibly inconsistent system of linear inequalities in the 1 sense is considered. The non-differentiable 1 norm minimization problem is approximated by a piecewise quadratic Huber smooth function. A continuation algorithm is designed to find an 1 solution of the inequality system.

Protected Chaos in a Topological Lattice

open access: yesAdvanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

Linear Inequality Concepts and Social Welfare [PDF]

open access: yes
The paper presents an abstract definition of linear inequality concepts leading to linearly invariant inequality measures and characterizes the class of linear concepts completely. Two general methods of deriving ethical measures are proposed. They imply

Neural Topology Optimization Via Active Learning for Efficient Channel Design in Turbulent Mass Transfer

open access: yesAdvanced Science, EarlyView.
This study introduces a neural operator‐assisted topology optimization framework for designing fluidic channel structures in mass transfer processes. By combining machine learning, gradient‐based optimization, and active data augmentation, the method enables high‐fidelity, efficient design.

Materials Selection Principles for Designing Electro‐Thermal Neurons

open access: yesAdvanced Electronic Materials, EarlyView.
Materials property – performance relations are established for new and old electrical materials leveraged as electro‐thermal oscillators emulating neuron dynamics. Robust, reconfigurable, high frequency, low power characteristics are explicitly tied to highly nonlinear electrical transport, small specific heat, and greater electrical than thermal ...

Increasing sedentary time, minimum dietary energy requirements, and food security assessment

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract We compute corrections for sedentary behavior in physical activity levels (PALs) and incorporate them along with corrections for over estimation of basal metabolic rates (BMRs) into threshold caloric intakes, known as minimum dietary energy requirements (MDERs).
