• 25th Anniversary Article: Ordered Polymer Structures for the Engineering of Photons and Phonons ﻿

(2014)
The engineering of optical and acoustic material functionalities via construction of ordered local and global architectures on various length scales commensurate with and well below the characteristic length scales of ...
• The 2nu-SVM: A Cost-Sensitive Extension of the nu-SVM ﻿

(2005-12-01)
Standard classification algorithms aim to minimize the probability of making an incorrect classification. In many important applications, however, some kinds of errors are more important than others. In this report we ...
• 3-D Local Radon Power Spectra for Seismic Attribute Extraction ﻿

(1998-01-15)
In this paper we discuss a method for volume attribute extraction that is based on a new type of local Radon power spectrum. The new algorithm results in robust and geologically meaningful volume attributes, such as ...
• 3-D segmentation and volume estimation of radiologic images by a novel, feature driven, region growing technique ﻿

(1992)
Magnetic Resonance (MR) imaging is a 3-D, multi-slice, radiological technique that acquires multiple intensities corresponding to each voxel. The transverse relaxation time, T$\sb1$, and the axial relaxation time, T$\sb2$, ...
• 3-Dimensional spatially organized PEG-based hydrogels for an aortic valve co-culture model ﻿

(2015)
Physiologically relevant inﾠvitro models are needed to study disease progression and to develop and screen potential therapeutic interventions for disease. Heart valve disease, in particular, has no early intervention or ...
• 3D bioprinting: improving in vitro models of metastasis with heterogeneous tumor microenvironments ﻿

(2017)
Even with many advances in treatment over the past decades, cancer still remains a leading cause of death worldwide. Despite the recognized relationship between metastasis and increased mortality rate, surprisingly little ...
• 3D Geometry Coding using Mixture Models and the Estimation Quantization Algorithm ﻿

(2002-09-01)
3D surfaces are used in applications such as animations, 3D object modeling and visualization. The geometries of such surfaces are often approximated using polygonal meshes. This thesis aims to compress 3D geometry meshes ...
• A 3D inﾠvitro model of patient-derived prostate cancer xenograft for controlled interrogation of inﾠvivo tumor-stromal interactions ﻿

(2016)
Patient-derived xenograft (PDX) models better represent human cancer than traditional cell lines. However, the complex in vivo environment makes it challenging to employ PDX models to investigate tumor-stromal interactions, ...

(2016)
Patient-derived xenograft (PDX) models better represent human cancer than traditional cell lines. However, the complex in vivo environment makes it challenging to employ PDX models to investigate tumor-stromal interactions, ...
• 3D Macroporous Solids from Chemically Cross-linked Carbon Nanotubes ﻿

(2014)
Suzuki reaction for covalently interconnected 3D carbon nanotube (CNT) architectures is reported. The synthesis of 3D macroscopic solids made of CNTs covalently connected via Suzuki cross-coupling, a well-known carbon-carbon ...
• 3D microfabrication of single-wall carbon nanotube/polymer composites by two-photon polymerization lithography ﻿

(2013)
We present a method to develop single-wall carbon nanotube (SWCNT)/polymer composites into arbitrary three-dimensional micro/nano structures. Our approach, based on two-photon polymerization lithography, allows one to ...
• 3D tissue-engineered model of Ewing's sarcoma ﻿

(2014)
Despite longstanding reliance upon monolayer culture for studying cancer cells, and numerous advantages from both a practical and experimental standpoint, a growing body of evidence suggests that more complex three-dimensional ...
• 802.11b Operating in a Mobile Channel: Performance and Challenges ﻿

(2003-09-20)
In the past, the worlds of wireless voice and data transmission have been largely disjoint. Voice traffic has been carried over circuit-switched cellular links, and data has been largely restricted to packet-switched ...
• A behavioral approach to positive interpolation ﻿

(2005)
We study interpolation by positive functions from a behavioural point of view. In particular, by considering the notion of mirror image data, the interpolation problem with passivity constraint is transformed into an ...
• A Characterization of Compound Documents on the Web ﻿

(1999-11-29)
Recent developments in office productivity suites make it easier for users to publish rich {\em compound documents\/} on the Web. Compound documents appear as a single unit of information but may contain data generated by ...
• A closed-loop model of the ovine cardiovascular system ﻿

(2003)
The conscious sheep is an important large animal model for the study of human cardiovascular and cardiopulmonary system. In this study we develop a closed-loop mathematical model of its cardiovascular system. A distributed ...
• A coding theoretic approach to image segmentation ﻿

(2001)
Using a coding theoretic approach, we achieve unsupervised image segmentation by implementing Rissanen's concept of Minimum Description Length (MDL) for estimating piecewise homogeneous regions in images. MDL offers a ...
• A communications and interaction model for intelligent cooperating robots ﻿

(1993)
In complex robotic operating environments in which robots must cooperate in a flexible and event-driven manner, a cooperative distributed environment for intelligent control is required. We develop a realistic technique ...
• A Comparison of Software Architectures for E-business Applications ﻿

(2002-02-20)
As dynamic content has become more prevalent on the Web, a number of standard mechanisms have evolved to generate such dynamic content. We study three specific mechanisms in common use: PHP, Java servlets, and Enterprise ...
• A Compressive Phase-Locked Loop ﻿

(2011)
We develop a new method for tracking narrowband signals acquired through compressive sensing, called the compressive sensing phase-locked loop (CS-PLL). The CS-PLL enables one to track oscillating signals in very large ...
