• #### Laminin Peptide-Immobilized Hydrogels Modulate Valve Endothelial Cell Hemostatic Regulation ﻿

(2015)
Valve endothelial cells (VEC) have unique phenotypic responses relative to other types of vascular endothelial cells and have highly sensitive hemostatic functions affected by changes in valve tissues. Furthermore, effects ...

• #### Large enhanced dielectric permittivity in polyaniline passivated core-shell nano magnetic iron oxide by plasma polymerization ﻿

(2014)
Commercial samples of Magnetite with size ranging from 25-30nm were coated with polyaniline by using radio frequency plasma polymerization to achieve a core shell structure of magnetic nanoparticle (core)-Polyaniline ...
• #### LASER PROCESSING OF SEMICONDUCTORS ﻿

(1982)
The great potential for advancing the state of the art in fabrication of semiconductor devices and integrated circuits with the use of laser beam processing techniques is reviewed. The unique characteristics of this novel ...
• #### Laser spectroscopic trace chemical sensors for environmental sensor networks and portable medical devices ﻿

(2008)
This thesis represents the development of the first laser spectroscopy based trace-gas sensors with sensor characteristics which simultaneously satisfy low cost, handheld footprint, low power, and long term autonomous ...
• #### Laser-assisted metalorganic chemical vapor deposition of zinc selenide ﻿

(1992)
Laser-assisted metalorganic chemical vapor deposition (LMOCVD) has been used to grow epitaxial zinc selenide at temperatures as low as 200$\sp\circ$C. The metalorganic sources, dimethylzinc (DMZ) and diethylselenide (DESe), ...
• #### Laser-assisted metalorganic chemical vapor deposition of zinc sulfide ﻿

(1997)
Laser-assisted metalorganic chemical vapor deposition (MOCVD) was used to grow crystalline zinc sulfide at temperatures as low as 200$\sp\circ$C. The metalorganic sources, dimethylzinc and diethylsulfide, were photodissociated ...
• #### Laser-induced porous graphene films from commercial polymers ﻿

(2014)
The cost effective synthesis and patterning of carbon nanomaterials is a challenge in electronic and energy storage devices. Here we report a one-step, scalable approach for producing and patterning porous graphene films ...
• #### A Lateral Flow Assay for Quantitative Detection of Amplified HIV-1 RNA ﻿

(2012)
Although the accessibility of HIV treatment in developing nations has increased dramatically over the past decade, viral load testing to monitor the response of patients receiving therapy is often unavailable. Existing ...
• #### Lattice Algorithms for Compression Color Space Estimation in JPEG Images ﻿

(2001-08-01)
JPEG (Joint Photographic Experts Group) is an international standard to compress and store digital color images [5]. Given a color image that was previously JPEG-compressed in some hidden color space, we aim to estimate ...
• #### Layered Dynamic Fault Detection and Tolerance for Robots ﻿

(1993-05-01)
Fault tolerance is increasingly important for space and hazardous environment robotics. Robots need to quickly detect and tolerate internal failures in order to continue performing their tasks without the need for immediate ...
• #### LDPC Code Design for Half-Duplex Decode-and-Forward Relaying ﻿

(2005-09-01)
We propose LDPC code designs for the half-duplex relay channel. Our designs mimic the information theoretic random coding scheme for decode-and-forward relaying. An important advantage of our scheme is that it is built ...
• #### LDPC Code Design for OFDM Channel: Graph Connectivity and Information Bits Positioning ﻿

(2005-07-01)
We present an optimized channel coding scheme for OFDM transmission. In the future wireless standards such IEEE 802.11n, frame error rates (FER) as low as 0.0001 are targeting. Irregular LDPC codes have excellent performance ...
• #### LDPC Code Design for Relay Channel in Time-Division mode ﻿

(2006-06-01)
We address the problem of LDPC code design for relay channel in time-division mode based on a distributed strategy: In the first time slot, the source transmits part of the codeword. The relay and the destination receive ...

• #### Learning minimum volume sets with support vector machines ﻿

(2006-09-01)
Given a probability law P on d-dimensional Euclidean space, the minimum volume set (MV-set) with mass beta , 0 < beta < 1, is the set with smallest volume enclosing a probability mass of at least beta. We examine the use ...
• #### Least square digital filter design in the frequency domain ﻿

(1991)
This thesis develops new methods for obtaining optimal frequency domain approximation in the design of digital filters. The approach uses a squared error approximation criterion and allows a transition band in the desired ...
• #### Leveraging synthetic biology for tissue engineering applications ﻿
