• 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 ...
• Lattice model of oligonucleotide hybridization in solution. II. Specificity and cooperativity ﻿

(2016)
Because oligonucleotides are short sequences of nucleic acid bases, their association in solution with complementary strands (hybridization) is often seen to conform to a simple two-state model. However, experimental ...
• 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 ...
• Lazy Release Consistency for Distributed Shared Memory ﻿

(1995-01)
A software distributed shared memory (DSM) system allows shared memory parallel programs to execute on networks of workstations. This thesis presents a new class of protocols that has lower communication requirements than ...
• 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 ...
• LDPC Code-Design for the Relay Channel ﻿

(2006-06-01)
We propose LDPC code designs for the half-duplex relay channel. Our designs are derived from the information theoretic random coding scheme for decode-and-forward relaying. An important advantage of our scheme is that it ...
• LDPC Code-Design for the Relay Channel ﻿

(2006-02-01)
We propose LDPC code designs for the half-duplex relay channel. Our designs are derived from the information theoretic random coding scheme for decode-and-forward relaying. An important advantage of our scheme is that it ...
• Leaky Buffer: A Novel Abstraction for Relieving Memory Pressure form Cluster Data Processing Frameworks ﻿

(2016-03-25)
The shift to the in-memory data processing paradigm has had a major influence on the development of cluster data processing frameworks. Numerous frameworks from the industry, open source community and academia are adopting ...
• 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 ...

(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 ...
• Lenslet array tunable snapshot imaging spectrometer (LATIS) for hyperspectral fluorescence microscopy ﻿

(2017)
Snapshot hyperspectral imaging augments pixel dwell time and acquisition speeds over existing scanning systems, making it a powerful tool for fluorescence microscopy. While most snapshot systems contain fixed datacube ...
• Leveraging synthetic biology for tissue engineering applications ﻿

(2014)
Restoration of damaged tissues and organs requires precise control of cellular processes at the molecular level. Synthetic biology offers genetic tools that can be used to program the molecular biology of the cell, thereby ...
• Levetiracetam mitigates doxorubicin-induced DNA and synaptic damage in neurons ﻿

(2016)
Neurotoxicity may occur in cancer patients and survivors during or after chemotherapy. Cognitive deficits associated with neurotoxicity can be subtle or disabling and frequently include disturbances in memory, attention, ...
