3-Cm Fine Structure Masers: A Unique Signature of Supermassive Black Hole Formation via Direct Collapse in the Early Universe
(American Astronomical Society, 2016)The direct collapse black hole (DCBH) scenario describes the isothermal collapse of a pristine gas cloud directly into a massive, M_BH=10^4-10^6 M_sun black hole. In this paper we show that large HI column densities of ... -
30,000 Years Old Wild Flax Fibers - Testimony for Fabricating Prehistoric Linen
(American Association for the Advancement of Science, 2009)A unique finding of wild flax fibers from a series of Upper Paleolithic layers at Dzudzuana Cave, located in the foothills of the Caucasus, Georgia, indicates that prehistoric hunter-gatherers were making cords for hafting ... -

3c 220.3: A Radio Galaxy Lensing a Submillimeter Galaxy
(IOP Publishing, 2014)Herschel Space Observatory photometry and extensive multiwavelength follow-up have revealed that the powerful radio galaxy (PRG) 3C 220.3 at z = 0.685 acts as a gravitational lens for a background submillimeter galaxy (SMG) ... -
3D Axon Structure Extraction and Analysis in Confocal Fluorescence Microscopy Images
(Massachusetts Institute of Technology Press, 2008)The morphological properties of axons, such as their branching patterns and oriented structures, are of great interest for biologists in the study of the synaptic connectivity of neurons. In these studies, researchers use ... -
3D Bioprinting of Vascularized Human Tissues
(2016-04-26)The ability to manufacture human tissues that replicate the spatial, mechano-chemical, and temporal aspects of biological tissues would enable myriad applications, including drug screening, disease modeling, and tissue ... -
3D Bioprinting of Vascularized, Heterogeneous Cell-Laden Tissue Constructs
(Wiley-Blackwell, 2014)A new bioprinting method is reported for fabricating 3D tissue constructs replete with vasculature, multiple types of cells, and extracellular matrix. These intricate, heterogeneous structures are created by precisely ... -
3D climate modeling of close-in land planets: Circulation patterns, climate moist bistability, and habitability
(EDP Sciences, 2013)The inner edge of the classical habitable zone is often defined by the critical flux needed to trigger the runaway greenhouse instability. This 1D notion of a critical flux, however, may not be all that relevant for ... -
3D Deformation Using Moving Least Squares
(2007)We present a 3d deformation method based on Moving Least Squares that extends the work by Schaefer et al. [Schaefer et al. 2006] to the 3d setting. The user controls the deformation by manipulating a set of point handles. ... -
3D modelling of the climatic impact of outflow channel formation events on early Mars
(Elsevier BV, 2017)Mars was characterized by cataclysmic groundwater-sourced surface flooding that formed large outflow channels and that may have altered the climate for extensive periods during the Hesperian era. In particular, it has been ... -
3D modelling of the early martian climate under a denser \(CO_2\) atmosphere: Temperatures and \(CO_2\) ice clouds
(Elsevier BV, 2013)On the basis of geological evidence, it is often stated that the early martian climate was warm enough for liquid water to flow on the surface thanks to the greenhouse effect of a thick atmosphere. We present 3D global ... -
3D Multicolor Super-Resolution Imaging Offers Improved Accuracy in Neuron Tracing
(Public Library of Science, 2012)The connectivity among neurons holds the key to understanding brain function. Mapping neural connectivity in brain circuits requires imaging techniques with high spatial resolution to facilitate neuron tracing and high ... -
3D Printing of Interdigitated Li-Ion Microbattery Architectures
(Wiley-Blackwell, 2013)3D interdigitated microbattery architectures (3D-IMA) are fabricated by printing concentrated lithium oxide-based inks. The microbatteries are composed of interdigitated, high-aspect ratio cathode and anode structures. Our ... -
3D Printing of Liquid Crystal Elastomer Actuators
(2021-07-12)Soft robotics offer advantages over their rigid counterparts due to the intrinsic softness of their consisting materials, soft robotic matter. When equipped with programmable shape morphing and controllable function, soft ... -
3D Printing of Transparent and Conductive Heterogeneous Hydrogel-Elastomer Systems
(Wiley-Blackwell, 2017)Hydrogel-based ionic devices represent an alternative approach to stretchable electronics through use of soft ionic conductors that are both highly stretchable and transparent. However, these devices require the integration ... -

3D Reconstruction Using Labeled Image Regions
(Eurographics Association, 2003)In this paper we present a novel algorithm for reconstructing 3D scenes from a set of images. The user defines a set of polygonal regions with corresponding labels in each image using familiar 2D photo-editing tools. Our ... -
3D TV: A Scalable System for Real-Time Acquisition, Transmission, and Autostereoscopic Display of Dynamic Scenes
(Association for Computing Machinery, 2004)Three-dimensional TV is expected to be the next revolution in the history of television. We implemented a 3D TV prototype system with real-time acquisition, transmission, and 3D display of dynamic scenes. We developed a ... -
3D Ultrasound-Guided Motion Compensation System for Beating Heart Mitral Valve Repair
(Springer Verlag, 2008)Beating heart intracardiac procedures promise significant benefits for patients, however, the fast motion of the heart poses serious challenges to surgeons. We present a new 3D ultrasound-guided motion (3DUS) compensation ...
