Dirac model of electronic transport in graphene antidot barriers

open access: yes, 2014
In order to use graphene for semiconductor applications, such as transistors with high on/off ratios, a band gap must be introduced into this otherwise semimetallic material.

Diagrammatic Algebra of First Order Logic [PDF]

open access: yesLogic in Computer Science
We introduce the calculus of neo-Peircean relations, a string diagrammatic extension of the calculus of binary relations that has the same expressivity as first order logic and comes with a complete axiomatisation.

Bayesian Probabilities and the Histories Algebra

open access: yes, 2006
We attempt a justification of a generalisation of the consistent histories programme using a notion of probability that is valid for all complete sets of history propositions.

Simultaneous Perfect Anomalous Reflection and Angle of Arrival Sensing in Reconfigurable Intelligent Surfaces

open access: yesAdvanced Optical Materials, Volume 13, Issue 13, May 5, 2025.
A reconfigurable intelligent surface is proposed that can simultaneously anomalously reflect the light and sense the angle of arrival. An in situ optimization of either the currents flowing on array elements or the far field in the receiver direction realizes anomalous reflection and suppresses parasitic scattering.

ZOO: Zeroth Order Optimization Based Black-box Attacks to Deep Neural Networks without Training Substitute Models [PDF]

open access: yesAISec@CCS, 2017
Deep neural networks (DNNs) are one of the most prominent technologies of our time, as they achieve state-of-the-art performance in many machine learning tasks, including but not limited to image classification, text mining, and speech processing ...

Complete Mode Spectrum Decomposition of Complex‐Structured Light by Computer‐Generated Holography

open access: yesAdvanced Photonics Research, Volume 6, Issue 2, February 2025.
In this article, a new optical method based on self‐interference is proposed to completely decompose the eigenmode spectrum of complex‐structured light. A diffractive optical method is designed and validated to extract the complete information of complex‐structured light fields composed with eigenmode superposition states, including the order of ...

Machine Learning Prediction of Tritium‐Helium Groundwater Ages in the Central Valley, California, USA

open access: yesWater Resources Research, Volume 61, Issue 1, January 2025.
Abstract Groundwater ages provides insight into recharge rates, flow velocities, and vulnerability to contaminants. The ability to predict groundwater ages based on more accessible parameters via Machine Learning (ML) would advance our ability to guide sustainable management of groundwater resources.

Adaptive fuzzy gain scheduling PID controller for frequency regulation in modern power system

open access: yesIET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
Abstract Here an adaptive fuzzy gain scheduling proportional, integral and derivative (FGPID) controller has been proposed for the load frequency control of a three‐area inter‐connected modern power system with the large‐scale wind‐power penetration in the presence of the vehicle‐to‐grid.

A Bayesian Analogue of Gleason's Theorem

open access: yes, 2006
We introduce a novel notion of probability within quantum history theories and give a Gleasonesque proof for these assignments. This involves introducing a tentative novel axiom of probability.

Transport properties of dense dissipitive hard-sphere fluids for arbitrary energy loss models [PDF]

open access: yes, 2005
The revised Enskog approximation for a fluid of hard spheres which lose energy upon collision is discussed for the case that the energy is lost from the normal component of the velocity at collision but is otherwise arbitrary.
