Decomposition driven interface evolution for layers of binary mixtures: I. Model dirivation and base states

Algebraic topology (homology) is used to analyze the state of spiral defect chaos in both laboratory experiments and numerical simulations of Rayleigh-Bénard convection. The analysis reveals topological asymmetries that arise when non-Boussinesq effects are present. The asymmetries are found in different flow fields in the simulations and are robust to substantial alterations to flow visualization conditions in the experiment. However, the asymmetries are not observable using conventional statistical measures. These results suggest homology may provide a new and general approach for connecting spatiotemporal observations of chaotic or turbulent patterns to theoretical models.

Notes about cases heard as Justice of the Peace, 1784-1795

This small paper-bound notebook contains notes Winthrop made concerning the cases he heard between 1784 and 1795 as a Justice of the Peace for Middlesex County. These notes provide insight into the nature of crimes being committed in Cambridge in the post-Revolutionary period, as well as the names and occupations of those accused and their victims. The cases involved the following individuals, among others: Samuel Bridge, Benjamin Estabrook, Joseph Jeffords, Cato Bordman, John Kidder, Spenser Goddin, Jacob Cromwell, Benjamin Stratton, Mary Flood, Bender Temple, John Willett, Joseph Hartwell, Nathaniel Stratton, Amos Washburn, Francis Moore, Thomas Malone, Thomas Cook, and Amboy Brown. The cases involved a range of offenses, and occasionally Winthrop decided that a case exceeded his jurisdiction and forwarded it to the General Court or the Supreme Judicial Court.

Letter from Edward Wigglesworth to John Lowell, 1781 January 3

Four leaves containing a four-and-a-half-page letter in the hand of Professor Edward Wigglesworth to John Lowell dated January 3, 1781. In the letter, Professor Wigglesworth describes the issues related to the deprecating value of paper money and the salaries of Harvard officers, and he provides recommendations for the General Court's grants to the College.

I. Sermons, 1709-1724

This series contains seventeen handwritten sermons composed by Nicholas Sever and delivered in the Boston area between 1709 and 1722. Following the completion of his Master's degree at Harvard in 1704, Sever preached in towns around New England including Haverhill in 1709, Dover, New Hampshire (where he was ordained in 1711 and remained until 1715), and in Cambridge as part of his duties as a Harvard Tutor between 1716 and 1728. During these years, Sever also filled in for ministers in nearby parishes. Sever's sermons reflect these engagements, and he occasionally noted the dates and locations where the sermons were delivered in the margin of the first page of the sermon.

The Report of the Committee appointed to Consid'n of the Memorial of the Overseers of Harvard College, 1722 June 29

Two folio-sized leaves containing a handwritten copy of a June 29, 1722 report created by a Committee of the General Court responding to the June 13, 1722 memorial of the Board of Overseers. The report lists three points declaring that the Charter of 1650 intended the Tutors to be members of the Corporation "provided they exceed not five in number," that none of the Fellows be Overseers, and that the Charter of 1650 did not grant the Corporation the power to set salaries without the consent of the Overseers. The copy notes that the report was read and accepted on June 29, and signed by Governor Samuel Shute on July 2, 1722, with the stipulation that none of the current non-resident Fellows be removed from the Corporation.

The Overseers present at these meetings doubted the act's legality and discussed ignoring and/or attempting to overturn the act.
