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 Basic Isolated Half-Bridge Silicon Carbide Gate Driver for Electric and Hybrid Electric Vehicles
(Massachusetts Institute of Technology, 2022-02)A Basic, Isolated, Half-Bridge Silicon Carbide Gate Driver was designed and validated using Cadence and SPICE. The architectures of similar gate drivers were studied and simplified to reduce the total area of the gate ... -
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 Better Bus Map: How Good Transit Map Design Can Strengthen the MBTA’s Bus System

A blood exchange method to study circulation kinetics of tumor cells in the blood
(Massachusetts Institute of Technology, 2023-06)Blood is an essential compartment for tumor cell trafficking. In solid epithelial-derived tumors, blood serves as the major vehicle for metastasis, whose principal cell is the circulating tumor cell (CTC). These cells ... -
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 Bridge Over the Chasm': Rhetoric and Reflexivity in Housing Advocacy
(Massachusetts Institute of Technology, 2021-06)As we cast housing in the language of crisis, development, shortage, and units, we lose sight of its value in the context of social relations and human wellbeing. The rhetoric that has evolved to explain gaps in housing ... -
