The Boston University Institutional Repository contains documents and publications authored or co-authored by BU faculty, students, and staff.

OpenBU is an open access repository, which means that the full text of the work deposited here is freely accessible to the world via the web. Access is restricted only in unavoidable instances, for example where publisher copyright restrictions prevail. However over 90% of scholarly publishers worldwide now allow some version of the documents they publish to be made available in a repository such as this.

  • Bandgap engineering of indium phosphide-based core/shell heterostructures through shell composition and thickness 

    Toufanian, Reyhaneh; Piryatinski, Andrei; Mahler, Andrew H.; Iyer, Radhika; Hollingsworth, Jennifer A.; Dennis, Allison M (FRONTIERS MEDIA SA, 2018-11-20)
    The large bulk bandgap (1.35 eV) and Bohr radius (~10 nm) of InP semiconductor nanocrystals provides bandgap tunability over a wide spectral range, providing superior color tuning compared to that of CdSe quantum dots. In ...
  • Revealing network structure, confidentially: improved rates for node-private graphon estimation 

    Borgs, Christian; Chayes, Jennifer; Smith, Adam; Zadik, Ilias (IEEE COMPUTER SOC, 2018-01-01)
    Motivated by growing concerns over ensuring privacy on social networks, we develop new algorithms and impossibility results for fitting complex statistical models to network data subject to rigorous privacy guarantees. We ...
  • A secure cloud with minimal provider trust 

    Mosayyebzadeh, Amin; Ravago, Gerardo; Mohan, Apoorve; Raza, Ali; Tikale, Sahil; Scheer, Nabil; Hudson, Trammell; Hennessy, Jason; Ansari, Naved; Hogan, Kyle; Munson, Charles; Rudolph, Larry; Cooperman, Gene; Desnoyers, Peter; Krieger, Orran (USENIX Association, 2018)
    Bolted is a new architecture for a bare metal cloud with the goal of providing security-sensitive customers of a cloud the same level of security and control that they can obtain in their own private data centers. It allows ...
  • The limits of post-selection generalization 

    Nissim, Kobbi; Smith, Adam; Steinke, Thomas; Stemmer, Uri; Ullman, Jonathan (2018-12-01)
    While statistics and machine learning offers numerous methods for ensuring generalization, these methods often fail in the presence of *post selection*---the common practice in which the choice of analysis depends on ...
  • Graph oracle models, lower bounds, and gaps for parallel stochastic optimization 

    Woodworth, Blake; Wang, Jialei; Smith, Adam; McMahan, Brendan; Srebro, Nati (2018-12-01)
    We suggest a general oracle-based framework that captures different parallel stochastic optimization settings described by a dependency graph, and derive generic lower bounds in terms of this graph. We then use the framework ...
  • Asymmetric synthesis of griffipavixanthone employing a chiral phosphoric acid-catalyzed cycloaddition 

    Smith, Michael J.; Reichl, Kyle D.; Escobar, Randolph A.; Heavey, Thomas J.; Coker, David F.; Schaus, Scott E.; Porco, John A. (AMER CHEMICAL SOC, 2019-01-09)
    Asymmetric synthesis of the biologically active xanthone dimer griffipavixanthone is reported along with its absolute stereochemistry determination. Synthesis of the natural product is accomplished via dimerization of a ...
  • Small molecule amyloid-beta protein precursor processing modulators lower amyloid-beta peptide levels via cKit signaling 

    Chen, Ci-Di; Zeldich, Ella; Khodr, Christina; Camara, Kaddy; Tung, Tze Yu; Lauder, Emma C.; Mullen, Patrick; Polanco, Taryn J.; Liu, Yen-Yu; Zeldich, Dean; Xia, Weiming; Van Nostrand, William E.; Brown, Lauren E.; Porco, John A.; Abraham, Carmela R. (IOS PRESS, 2019-01-01)
    Alzheimer’s disease (AD) is characterized by the accumulation of neurotoxic amyloid-β (Aβ) peptides consisting of 39-43 amino acids, proteolytically derived fragments of the amyloid-β protein precursor (AβPP), and the ...
  • The role of liquid ink transport in the direct placement of quantum dot emitters onto sub-micrometer antennas by dip-pen nanolithography 

    Dawood, Farah; Wang, Jun; Schulze, Peter A.; Sheehan, Chris J.; Buck, Matthew R.; Dennis, Allison M.; Majumder, Somak; Krishnamurthy, Sachi; Ticknor, Matthew; Staude, Isabelle; Brener, Igal; Goodwin, Peter M.; Amro, Nabil A.; Hollingsworth, Jennifer A. (WILEY-V C H VERLAG GMBH, 2018-08-02)
    Dip‐pen nanolithography (DPN) is used to precisely position core/thick‐shell (“giant”) quantum dots (gQDs; ≥10 nm in diameter) exclusively on top of silicon nanodisk antennas (≈500 nm diameter pillars with a height of ≈200 ...
  • Scheler on shame 

    Dahlstrom, Daniel
    This paper presents a critical review of Scheler’s analysis of shame's structure, dynamic, and affectivity, and his explanation of phenomena of shame. This first part of the paper examines Scheler’s accounts of shame’s ...
