A 3D Interconnected Microchannel Network Formed in Gelatin by Sacrificial Shellac Microfibers
(Wiley, 2012)3D microfluidic networks are fabricated in a gelatin hydrogel using sacrificial melt-spun microfibers made from a material with pH-dependent solubility. The fibers, after being embedded within the gel, can be removed by ... -
A 3D microvascular network model to study the impact of hypoxia on the extravasation potential of breast cell lines
(Springer Nature, 2018)© 2018, The Author(s). Hypoxia is a common feature of the tumor microenvironment. Accumulating evidence has demonstrated hypoxia to be an important trigger of tumor cell invasion or metastasizes via hypoxia-signaling ... -
A Bayesian state-space approach for damage detection and classification
(Elsevier BV, 2017)© 2017 Elsevier Ltd The problem of automatic damage detection in civil structures is complex and requires a system that can interpret collected sensor data into meaningful information. We apply our recently developed ... -
A Belief Propagation Algorithm for Multipath-Based SLAM
(Institute of Electrical and Electronics Engineers (IEEE), 2019)© 2002-2012 IEEE. We present a simultaneous localization and mapping (SLAM) algorithm that is based on radio signals and the association of specular multipath components (MPCs) with geometric features. Especially in indoor ... -
A Blood-Resistant Surgical Glue for Minimally Invasive Repair of Vessels and Heart Defects
(American Association for the Advancement of Science (AAAS), 2014)Currently, there are no clinically approved surgical glues that are nontoxic, bind strongly to tissue, and work well withinwet and highly dynamic environments within the body. This is especially relevant tominimally invasive ... -
A brief review of genome editing technology for generating animal models
(Editorial Department of Engineering Sciences, 2020)© The Author(s) 2020. The recent development of genome editing technologies has given researchers unprecedented power to alter DNA sequences at chosen genomic loci, thereby generating various genetically edited animal ... -
A BUCKLING FLEXURE-BASED FORCE-LIMITING MECHANISM
(ASME International, 2019)Copyright © 2019 by ASME. A force-limiting buckling flexure has been created which can be used in a wide range of applications where excessive force from an implement can cause harm or damage. The buckling flexure is ... -
A census of cool-core galaxy clusters in IllustrisTNG
(Oxford University Press (OUP), 2018)© 2018 The Author(s). The thermodynamic structure of hot gas in galaxy clusters is sensitive to astrophysical processes and typically difficult to model with galaxy formation simulations. We explore the fraction of cool-core ... -
A Characterization of Guesswork on Swiftly Tilting Curves
(Institute of Electrical and Electronics Engineers (IEEE), 2019)© 1963-2012 IEEE. Given a collection of strings, each with an associated probability of occurrence, the guesswork of each of them is their position in a list ordered from most likely to least likely, breaking ties arbitrarily. ... -
A CHARACTERIZATION OF MODIFIED MOCK THETA FUNCTIONS
(Springer Nature, 2017)© 2016, Springer Science+Business Media New York. We give a characterization of modified (in the sense of Zwegers) mock theta functions, parallel to that of ordinary theta functions. Namely, modified mock theta functions ... -
A combined photoionization time-of-flight mass spectrometry and laser absorption spectrometry flash photolysis apparatus for simultaneous determination of reaction rates and product branching
(AIP Publishing, 2018)© 2018 Author(s). In recent years, predictions of product branching for reactions of consequence to both combustion and atmospheric chemistry have outpaced validating experiments. An apparatus is described that aims to ... -
A comparative genomics multitool for scientific discovery and conservation
(Springer Science and Business Media LLC, 2020-11-12)© 2020, The Author(s). The Zoonomia Project is investigating the genomics of shared and specialized traits in eutherian mammals. Here we provide genome assemblies for 131 species, of which all but 9 are previously ... -
