High-Resolution Mapping In Manus Basin, C. Roman, V. Ferrini

Christopher N. Roman

Near-bottom seafloor mapping with precisely navigated deep submergence vehicles has become increasingly common in a range of oceanographic settings. Recent mapping efforts at deep-water hydrothermal vent sites have resulted in high-resolution (sub-meter) bathymetry datasets that can be used to identify morphological features associated with volcanic, tectonic, and hydrothermal processes. The resolution of these maps, and our ability to accurately quantify the complex morphologic details of hydrothermal structures has been limited by a number of variables including navigational accuracy, sonar settings (e.g. acoustic wavelength, sonar orientation, ping rate), survey parameters (e.g. altitude, speed), data density, and data processing techniques (e.g. gridding …

Comparing Linkages Of Real Estate And Construction By The Consideration Of The Impact Of Capital, Yu Song, Chunlu Liu, Craig Langston

Craig Langston

Based on the recently published Organisation for Economic Co-operation and Development (OECD) input-output database at constant prices, this research proposes a new model to compare the linkages of the construction and real estate sectors in national economies with the consideration of the impact of capital. Empirical results indicate that the linkages are extremely underestimated in previous research. The backward and forward linkages of the real estate sector are smaller than those of the construction sector, which means in economic development, construction plays a more important role than real estate, given the impact of capital. More importantly, the findings prove that …

Consistency Based Error Evaluation For Deep Sea Bathymetric Mapping With Robotic Vehicles, Christopher Roman, Hanumant Singh

Christopher N. Roman

This paper presents a method to evaluate the mapping error present in point cloud terrain maps created using robotic vehicles and range sensors. This work focuses on mapping environments where no a priori ground truth is available and self consistency is the only available check against false artifacts and errors. The proposed error measure is based on a disparity measurement between common sections of the environment that have been imaged multiple times. This disparity measure highlights inconsistency in the terrain map by showing regions where multiple overlapping point clouds do not fit together well. This error measure provides the map …

Application Of Inkjet Printing To Tissue Engineering, Thomas Boland, Tao Xu, Brook Damon, Xiaofeng Cui

Thomas Boland

ecent advances in organ printing technology for applications relating to medical interventions and organ replacement are described. Organ printing refers to the placement of various cell types into a soft scaffold fabricated according to a computer-aided design template using a single device. Computer aided scaffold topology design has recently gained attention as a viable option to achieve function and mass transport requirements within tissue engineering scaffolds. An exciting advance pioneered in our laboratory is that of simultaneous printing of cells and biomaterials, which allows precise placement of cells and proteins within 3-D hydrogel structures. This advance raises the possibility of …

The Use Of Extracellular Matrix As An Inductive Scaffold For The Partial Replacement Of Functional Myocardium., Glenn Gaudette, S Badylak, P Kochupura, I Cohen, S Doronin, A Saltman, T Gilbert, D Kelly, R Ignotz

Glenn R. Gaudette

Regenerative medicine approaches for the treatment of damaged or missing myocardial tissue include cell-based therapies, scaffold-based therapies, and/or the use of specific growth factors and cytokines. The present study evaluated the ability of extracellular matrix (ECM) derived from porcine urinary bladder to serve as an inductive scaffold for myocardial repair. ECM scaffolds have been shown to support constructive remodeling of other tissue types including the lower urinary tract, the dermis, the esophagus, and dura mater by mechanisms that include the recruitment of bone marrow-derived progenitor cells, angiogenesis, and the generation of bioactive molecules that result from degradation of the ECM. …

Viability And Electrophysiology Of Neural Cell Structures Generated By The Inkjet Printing Method, Tao Xu, Cassie Gregory, Peter Molnar, S Jalota, Sarit Bhaduri, Thomas Boland

Thomas Boland

Complex cellular patterns and structures were created by automated and direct inkjet printing of primary embryonic hippocampal and cortical neurons. Immunostaining analysis and whole-cell patch-clamp recordings showed that embryonic hippocampal and cortical neurons maintained basic cellular properties and functions, including normal, healthy neuronal phenotypes and electrophysiological characteristics, after being printed through thermal inkjet nozzles. In addition, in this study a new method was developed to create 3D cellular structures: sheets of neural cells were layered on each other (layer-by-layer process) by alternate inkjet printing of NT2 cells and fibrin gels. These results and findings, taken together, show that inkjet printing …
