The Diary of Colonel Israel Angell Commanding Officer, 2nd Rhode Island Regiment, Continental Army

This document includes the full text of Colonel Israel Angell\u27s Diaries compiled by Edward Field and published in 1899. It also includes the text of three manuscript diaries from the collections of the Massachusetts Historical Society in Boston, Massachusetts. These diaries were transcribed and digitized by Norman Desmarais and inserted in their proper location in Field\u27s text. The diaries are organized here by the year of coverage rather than by the individual manuscripts as in Field\u27s book. The five chronological sections of this combined text are also available as individual downloads in the supplemental materials section of this page

Proofs of the Results in “Boundary-Value Problems for Weakly Nonlinear Ordinary Differential Equations”

We provide the proofs of the results, announced in [1], concerning the existence (and non-existence) of solutions to Dirichlet and periodic boundary value problems associated to second order differential equations with asymmetric nonlinearities

The Uptake Of Radioactive Iodine, 1 131, By Various Organs In Euthyroid And Hypothyroid Rats

More than 375 radioactive isotopes of the common chemical elements have been produced by nuclear bombardment. These include isotopes of every known stable chemical element. Many have proved exceptionally useful in biological and medical experimentation (7). The use of isotopes as tracers in the study of biological and other systems has been widely applied. The utilization of isotopes constitutes an extremely powerful method of studying the complex systems encounted in living organisms under equilibrium conditions without interacting, to any appreciable extent, with the system (16). Chief among the advantages of radioactive isotopes in medical investigative work is the ability to· discriminate between these tracers and their nonradioactive counterpart already present in the organism (11). The existence of elements practically identical in chemical properties, yet differing in mass, became known through study of radioactive decay. An example is one of the decay products of radium D, which occupies the same place in the periodic table as lead, is practically identical in chemical properties with ordinary lead and is apparently inseparable from it but at the same time differs in mass. To such elements of differing masses occupying the same place in the periodic table, were given the name isotopes (Greek, equal place). In time it became quite clear that the atomic number and not the atomic weight determined the place of an element in the periodic table (16). Aston (3) demonstrated that many lights, non-radioactive elements were mixtures of atoms of more than one mass species occupying the same place in the periodic table, that is, they were mixtures of isotopes. Aston\u27s (3) work not only clearly demonstrated the existence of stable isotopes, but furnishes the means, and the mass spectrograph of measuring accurately the mass and the relative abundance of an element

Overcoming migration during giant planet formation

In the core accretion model, gas giant formation is a race between growth and migration; for a core to become a jovian planet, it must accrete its envelope before it spirals into the host star. We use a multizone numerical model to extend our previous investigation of the "window of opportunity" for gas giant formation within a disk. When the collision cross-section enhancement due to core atmospheres is taken into account, we find that a broad range of protoplanetary disks posses such a window.Comment: 4 pages, 3 figs, accepted to ApJ

Carl Van Vechten\u27s Nigger Heaven: Envisioning and Reinventing American Transatlantic Bohemia in Harlem

This study of Carl Van Vechten\u27s controversial novel, Nigger Heaven, creates a transatlantic model as a new platform to judge Van Vechten\u27s work. The paper sets forth the argument that Van Vechten\u27s importance in the modernist movement, as well as his significant contribution to the Harlem Renaissance, is a worthwhile addition to studies in the field. An analysis of transatlantic modernism is developed in context with Van Vechten\u27s earlier works. The study culminates with a close reading of the multiple elements of transatlantic/transnational/cosmopolitan elements of Harlem presented in Nigger Heaven

On the Effectiveness of Retrieval, Alignment, and Replay in Manipulation

Imitation learning with visual observations is notoriously inefficient when addressed with end-to-end behavioural cloning methods. In this paper, we explore an alternative paradigm which decomposes reasoning into three phases. First, a retrieval phase, which informs the robot what it can do with an object. Second, an alignment phase, which informs the robot where to interact with the object. And third, a replay phase, which informs the robot how to interact with the object. Through a series of real-world experiments on everyday tasks, such as grasping, pouring, and inserting objects, we show that this decomposition brings unprecedented learning efficiency, and effective inter- and intra-class generalisation.

DINOBot: Robot Manipulation via Retrieval and Alignment with Vision Foundation Models

We propose DINOBot, a novel imitation learning framework for robot manipulation, which leverages the image-level and pixel-level capabilities of features extracted from Vision Transformers trained with DINO. When interacting with a novel object, DINOBot first uses these features to retrieve the most visually similar object experienced during human demonstrations, and then uses this object to align its end-effector with the novel object to enable effective interaction. Through a series of real-world experiments on everyday tasks, we show that exploiting both the image-level and pixel-level properties of vision foundation models enables unprecedented learning efficiency and generalisation.
