LS-APC v1.0: a tuning-free method for the linear inverse problem and its application to source-term determination [PDF]

open access: yesGeoscientific Model Development, 2016
Estimation of pollutant releases into the atmosphere is an important problem in the environmental sciences. It is typically formalized as an inverse problem using a linear model that can explain observable quantities (e.g., concentrations or ...

Adaptive slices for acquisition of anisotropic BRDF

open access: yesComputational Visual Media, 2018
BRDF continues to be used as a fundamental tool for representing material appearance in computer graphics. In this paper we present a practical adaptive method for acquisition of anisotropic BRDF, based on sparse adaptive measurement of the complete four-

Quantum coherence on selectivity and transport of ion channels

open access: yesScientific Reports, 2022
Recently, it has been suggested that ion channel selectivity filter may exhibit quantum coherence, which may be appropriate to explain ion selection and conduction processes. Potassium channels play a vital role in many physiological processes.

Information Theory for Fields [PDF]

open access: yesAnnals of Physics, 2018
A physical field has an infinite number of degrees of freedom since it has a field value at each location of a continuous space. Therefore, it is impossible to know a field from finite measurements alone and prior information on the field is essential ...

An Optimality Summary: Secret Key Agreement with Physical Unclonable Functions

open access: yesEntropy, 2020
We address security and privacy problems for digital devices and biometrics from an information-theoretic optimality perspective to conduct authentication, message encryption/decryption, identification or secure and private computations by using a secret

Approximate Synchronization of Complex Network Consisting of Nodes With Minimum-Phase Zero Dynamics and Uncertainties

open access: yesIEEE Access, 2022
A synchronization algorithm of nonlinear complex networks composed of nonlinear nodes is designed. The main idea is to apply the exact feedback linearization of every node first, then applying methods for synchronization of linear complex networks.

Bounds on the Capacity of the Relay Channel with Noncausal State Information at Source

open access: yes, 2010
We consider a three-terminal state-dependent relay channel with the channel state available non-causally at only the source. Such a model may be of interest for node cooperation in the framework of cognition, i.e., collaborative signal transmission ...
