Analyzing linearizability violations in the presence of read-modify-write operations
(Elsevier, 2018-10-01)We consider an algorithmic problem related to analyzing consistency anomalies in distributed storage systems. Specifically, given a history of read, write, and read-modify-write operations applied by clients, we quantify ... -
Assessment of Germanane Field-Effect Transistors for CMOS Technology
(Institute of Electrical and Electronics Engineers, 2017-10-13)Using self-consistent atomistic quantum transport simulations, the device characteristics of n-type and p-type germanane (GeH) field-effect transistors (FETs) are evaluated. While both devices exhibit near-identical off-state ... -
Assessment of High-Frequency Performance Limit of Black Phosphorus Field-Effect Transistors
(Institute of Electrical and Electronics Engineers, 2017-05-18)Recently gigahertz frequencies have been reported with black phosphorus (BP) field-effect transistors (FETs), yet the high-frequency performance limit has remained unexplored. Here we project the frequency limit of BP FETs ... -
Blockchain for Transparent Data Management Toward 6G
(Elsevier, 2021-07)The wealth of user data acts as a fuel for network intelligence toward the sixth generation wireless networks (6G). Due to data heterogeneity and dynamics, decentralized data management (DM) is desirable for achieving ... -
A Composable Worst Case Latency Analysis for Multi-Rank DRAM Devices under Open Row Policy
(Springer, 2017-04-12)As multi-core systems are becoming more popular in real-time embedded systems, strict timing requirements for accessing shared resources must be met. In particular, a detailed latency analysis for Double Data Rate Dynamic ... -
Coordinated path following of unicycles : A nested invariant sets approach
(Elsevier, 2015)We formulate a coordinated path following problem for N unicycle mobile robots as an instance of a nested set stabilization problem. Stabilization of the first set corresponds to driving the unicycles to their assigned ... -
Design Strategy of 2D Material Field-Effect Transistors: Engineering the Number of Layers in Phosphorene FETs
(AIP Publishing, 2016-06-07)Thickness or the number of layers in 2D semiconductors is a key parameter to determine the material’s electronic properties and the overall device performance of 2D material electronics. Here we discuss the engineering ... -
Enhanced photo-stability of inverted organic solar cells via using polyethylenimine in the electron extraction layers
(Elsevier, 2019-10)The influence of using Polyethylenimine (PEI) in the electron extraction layers (EELs) on the photo-stability of inverted organic solar cells (OSCs) is investigated. Results show that introducing PEI in the commonly used ... -
Fine-grained data access control with attribute-hiding policy for cloud-based IoT
(Elsevier, 2019-04-22)Ciphertext-policy attribute-based encryption (CP-ABE) is a promising approach to achieve fine-grained access control over the outsourced data in Internet of Things (IoT). However, in the existing CP-ABE schemes, the access ... -
Global Sampled-Data Regulation of a Class of Fully Actuated Invariant Systems on Simply Connected Nilpotent Matrix Lie Groups
(IEEE, 2021-02-09)We examine a regulator problem for a class of fully actuated continuous-time invariant systems on Lie groups, using a discrete-time controller with constant sampling period. We present a smooth discrete-time control law ... -
Global Stability of a Class of Difference Equations on Solvable Lie Algebras
(Springer, 2020-06-17)Motivated by the ubiquitous sampled-data setup in applied control, we examine the stability of a class of difference equations that arises by sampling a right- or left-invariant flow on a solvable matrix Lie group. The map ... -
Global-connected network with generalized ReLU activation
(Elsevier, 2019-12)Recent Progress has shown that exploitation of hidden layer neurons in convolutional neural networks (CNN) incorporating with a carefully designed activation function can yield better classification results in the field ... -
Hillock-free and atomically smooth InSb QWs grown on GaAs substrates by MBE

Image-based spatio-temporal model of drug delivery in a heterogeneous vasculature of a solid tumor — Computational approach
(Elsevier, 2019-05)The solute transport distribution in a tumor is an important criterion in the evaluation of the cancer treatment efficacy. The fraction of killed cells after each treatment can quantify the therapeutic effect and plays as ... -
Local nested transverse feedback linearization
(Springer, 2015-08-29)We study two local feedback equivalence problems for a nonlinear control-affine system with two nested, controlled-invariant, embedded submanifolds in its state space. The first, less restrictive, result gives necessary ... -
Local observers on linear Lie groups with linear estimation error dynamics
