1,4-Dioxane-degrading consortia can be enriched from uncontaminated soils: prevalence of Mycobacterium and soluble di-iron monooxygenase genes
(2017)Two bacterial consortia were enriched from uncontaminated soil by virtue of their ability to grow on 1,4-dioxane (dioxane) as a sole carbon and energy source. Their specific dioxane degradation rates at 30°C, pH = 7 (i.e. ... -
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 ... -
2D and 2.5D Kirchhoff Inversion Using Upwind Finite Difference Amplitudes
(1996-07)Finite difference solution of the transport equation provides an efficient and accurate method for computation of 2.5D geometric acoustics amplitudes. These amplitudes can be used in simulation, migration and inversion ... -
2D material integrated macroporous electrodes for Li-ion batteries
(2017)Three-dimensionally structured architectures are known to improve the performance of electrodes used in Li ion battery systems. In addition, integration of select 2D materials into 3D structures, for enhancing both electrical ... -
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, ... -

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 printed fiber optic faceplates by custom controlled fused deposition modeling
(2018)A 3D printing technique for manufacturing air-clad coherent fiber optic faceplates is presented. The custom G-code programming is implemented on a fused deposition modeling (FDM) desktop printer to additively draw optical ... -
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 Ball and Beam Module for a Haptic Paddle Education Platform
(2017)Single degree of freedom force-feedback mechatronic devices, often called haptic paddles, are used in university curriculum as well as massive open online courses (MOOCs). While devices differ based on the goals of a given ... -
A Bayesian Integrative Model for Genetical Genomics with Spatially Informed Variable Selection
(2014)We consider a Bayesian hierarchical model for the integration of gene expression levels with comparative genomic hybridization (CGH) array measurements collected on the same subjects. The approach defines a measurement ... -
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 ...
