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 Printing Soft Materials: What Is Possible?

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 ... -
3D-printed spherical dipole antenna integrated on small RF node
(Institution of Engineering and Technology (IET), 2015)New three-dimensional (3D) printing techniques enable the integration of an antenna directly onto the package of a small wireless sensor node. This volume-filling approach ensures near-optimal bandwidth performance of the ... -
A 3D-printed, functionally graded soft robot powered by combustion
(American Association for the Advancement of Science (AAAS), 2015)Roboticists have begun to design biologically inspired robots with soft or partially soft bodies, which have the potential to be more robust and adaptable, and safer for human interaction, than traditional rigid robots. ... -

A 4% Geometric Distance to the Galaxy NGC4258 from Orbital Motions in a Nuclear Gas Disk
(Springer Nature, 1999)The accurate measurement of extragalactic distances is a central challenge of modern astronomy, being required for any realistic description of the age, geometry and fate of the Universe. The measurement of relative ... -
A 4-DOF Robot for Positioning Ultrasound Imaging Catheters
(American Society of Mechanical Engineers, 2015)In this paper we present the design, fabrication, and testing of a robot for automatically positioning ultrasound imaging catheters. Our system will point ultrasound (US) catheters to provide real-time imaging of anatomical ... -
4-Manifolds With Inequivalent Symplectic Forms and 3-Manifolds With Inequivalent Fibrations
(International Press, 1999)We exhibit a closed, simply connected 4-manifold \(X\) carrying two symplectic structures whose first Chern classes in \(H^2 (X, \mathbb{Z})\) lie in disjoint orbits of the diffeomorphism group of \(X\). Consequently, the ... -
4-Phenylbutyrate Attenuates the ER Stress Response and Cyclic AMP Accumulation in DYT1 Dystonia Cell Models
(Public Library of Science, 2014)Dystonia is a neurological disorder in which sustained muscle contractions induce twisting and repetitive movements or abnormal posturing. DYT1 early-onset primary dystonia is the most common form of hereditary dystonia ... -
The 4.5 µm full-orbit phase curve of the hot Jupiter HD 209458B
(IOP Publishing, 2014)The hot Jupiter HD 209458b is particularly amenable to detailed study as it is among the brightest transiting exoplanet systems currently known (V-mag = 7.65; K-mag = 6.308) and has a large planet-to-star contrast ratio. ... -
4d Spectra from BPS Quiver Dualities
(2013-09-26)We attack the question of BPS occupancy in a wide class of 4d N = 2 quantum field theories. We first review the Seiberg-Witten approach to finding the low energy Wilsonian effective action actions of such theories. In ...
