Sampling-based robotic information gathering algorithms

Creator:: Hollinger, Geoffrey A. and Sukhatme, Gaurav S.
Abstract:: We propose three sampling-based motion planning algorithms for generating informative mobile robot trajectories. The goal is to find a trajectory that maximizes an information quality metric (e.g. variance reduction, information gain, or mutual information) and also falls within a pre-specified budget constraint (e.g. fuel, energy, or time). Prior algorithms have...

Distributed Data Fusion for Multirobot Search

Creator:: Hollinger, Geoffrey A., Yerramalli, Srinivas, Singh, Sanjiv, Mitra, Urbashi, and Sukhatme, Gaurav S.
Abstract:: This paper presents novel data fusion methods that enable teams of vehicles to perform target search tasks without guaranteed communication. Techniques are introduced for merging estimates of a target’s position from vehicles that regain contact after long periods of time, and a fully distributed team planning algorithm is proposed that...

Learning Uncertainty in Ocean Current Predictions for Safe and Reliable Navigation of Underwater Vehicles

Creator:: Hollinger, Geoffrey A., Pereira, Arvind A., Binney, Jonathan, Somers, Thane, and Sukhatme, Gaurav S.
Abstract:: Operating autonomous underwater vehicles (AUVs) near shore is challenging—heavy shipping traffic and other hazards threaten AUV safety at the surface, and strong ocean currents impede navigation when underwater. Predictive models of ocean currents have been shown to improve navigation accuracy, but these forecasts are typically noisy, making it challenging to...

Bacterial hydrophobicity : assessment techniques, applications and extension to colloids

Creator:: Saini, Gaurav
Abstract:: This research details laboratory assessment of bacterial hydrophobicity, variations in bacterial adhesion properties with growth and extended starvation as well as extension of this assay to colloidal hydrophobicity measurement. Hydrophobicity is an integral component of surface interactions and has been studied extensively for its role in a number of engineering...

Systemically Delivered Magnetic Hyperthermia for Cancer Treatment

Creator:: Albarqi, Hassan Ahmad M.
Abstract:: Despite advances in treatment, cancer remains among the leading causes of death in the world. Progress in the treatment of metastatic cancers was seen with chemotherapy and radiotherapy, however, the major drawbacks of conventional cancer therapies are limited efficacy and severe side effects. Magnetic fluid hyperthermia (MFH) is a new...

A Nanoparticle Mediated Gene Silencing Approach for the Treatment of Metastatic Ovarian Cancer

Creator:: Schumann, Canan B.
Abstract:: Ovarian cancer, “the silent killer,” is one of the deadliest gynecological diseases due to delayed diagnosis, leading to a heavily disseminated and aggressive metastatic cancer. Therapeutic options are limited at stages III-IV of ovarian cancer, in which debulking surgery and cytotoxic chemotherapy remain the mainstays of intervention. However, these therapeutic...

Delayed Cutaneous Wound Healing and Aberrant Expression of Hair Follicle Stem Cell Markers in Mice Selectively Lacking Ctip2 in Epidermis

Creator:: Liang, Xiaobo, Bhattacharya, Shreya, Bajaj, Gaurav, Guha, Gunjan, Wang, Zhixing, Jang, Hyo-Sang, Leid, Mark, Indra, Arup Kumar, and Ganguli-Indra, Gitali
Abstract:: Background: COUP-TF interacting protein 2 [(Ctip2), also known as Bcl11b] is an important regulator of skin homeostasis, and is overexpressed in head and neck cancer. Ctip2(ep-/-) mice, selectively ablated for Ctip2 in epidermal keratinocytes, exhibited impaired terminal differentiation and delayed epidermal permeability barrier (EPB) establishment during development, similar to what...

Phylotastic! Making tree-of-life knowledge accessible, reusable and convenient

Creator:: Stoltzfus, Arlin, Lapp, Hilmar, Matasci, Naim, Deus, Helena, Sidlauskas, Brian, Zmasek, Christian M., Vaidya, Gaurav, Pontelli, Enrico, Cranston, Karen, Vos, Rutger, Webb, Campbell O, Harmon, Luke J., Pirrung, Megan, O'Meara, Brian, Pennell, Matthew W., Mirarab, Siavash, Rosenberg, Michael S., Balhoff, James P., Bik, Holly M., Heath, Tracy A., Midford, Peter E., Brown, Joseph W., McTavish, Emily Jane, Sukumaran, Jeet, Westneat, Mark, Alfaro, Michael E., Steele, Aaron, and Jordan, Greg
Abstract:: Background: Scientists rarely reuse expert knowledge of phylogeny, in spite of years of effort to assemble a great “Tree of Life” (ToL). A notable exception involves the use of Phylomatic, which provides tools to generate custom phylogenies from a large, pre-computed, expert phylogeny of plant taxa. This suggests great potential...

Optimized production of Serratia marcescens B742 mutants for preparing chitin from shrimp shells powders

Creator:: Zhang, Hongcai, Fang, Jiyang, Deng, Yun, and Zhao, Yanyun
Abstract:: To improve the deproteinization (DP) efficacy of shrimp shell powders (SSP) for preparing chitin, Serratia marcescens B742 mutants were prepared using 2% diethyl sulfate (DES), UV-irradiation, and/or microwave heating treatments. Both single-stage and multi-stage mutations were investigated for optimizing S. marcescens B742 mutation conditions. Under the optimized mutation conditions (2%...
