    Due to advances in electron microscopy and deep learning, it is now practical to reconstruct a connectome, a description of neurons and the chemical synapses between them, for significant volumes of neural tissue. Smaller past reconstructions were primarily used by domain experts, could be handled by downloading data, and performance was not a serious problem. But new and much larger reconstructions upend these assumptions. These networks now contain tens of thousands of neurons and tens of millions of connections, with yet larger reconstructions pending, and are of interest to a large community of non-specialists. Allowing other scientists to make use of this data needs more than publicationā€”it requires new tools that are publicly available, easy to use, and efficiently handle large data. We introduce neuPrint to address these data analysis challenges. Neuprint contains two major componentsā€”a web interface and programmer APIs. The web interface is designed to allow any scientist worldwide, using only a browser, to quickly ask and answer typical biological queries about a connectome. The neuPrint APIs allow more computer-savvy scientists to make more complex or higher volume queries. NeuPrint also provides features for assessing reconstruction quality. Internally, neuPrint organizes connectome data as a graph stored in a neo4j database. This gives high performance for typical queries, provides access though a public and well documented query language Cypher, and will extend well to future larger connectomics databases. Our experience is also an experiment in open science. We find a significant fraction of the readers of the article proceed to examine the data directly. In our case preprints worked exactly as intended, with data inquiries and PDF downloads starting immediately after pre-print publication, and little affected by formal publication later. From this we deduce that many readers are more interested in our data than in our analysis of our data, suggesting that data-only papers can be well appreciated and that public data release can speed up the propagation of scientific results by many months. We also find that providing, and keeping, the data available for online access imposes substantial additional costs to connectomics research

    Too Big to Fail ā€” U.S. Banksā€™ Regulatory Alchemy: Converting an Obscure Agency Footnote into an ā€œAt Willā€ Nullification of Dodd-Frankā€™s Regulation of the Multi-Trillion Dollar Financial Swaps Market

    The multi-trillion-dollar market for, what was at that time wholly unregulated, over-the-counter derivatives (ā€œswapsā€) is widely viewed as a principal cause of the 2008 worldwide financial meltdown. The Dodd-Frank Act, signed into law on July 21, 2010, was expressly considered by Congress to be a remedy for this troublesome deregulatory problem. The legislation required the swaps market to comply with a host of business conduct and anti-competitive protections, including that the swaps market be fully transparent to U.S. financial regulators, collateralized, and capitalized. The statute also expressly provides that it would cover foreign subsidiaries of big U.S. financial institutions if their swaps trading could adversely impact the U.S. economy or represent the use of extraterritorial trades as an attempt to ā€œevadeā€ Dodd-Frank. In July 2013, the CFTC promulgated an 80-page, triple-columned, and single-spaced ā€œguidanceā€ implementing Dodd-Frankā€™s extraterritorial reach, i.e., that manner in which Dodd-Frank would apply to swaps transactions executed outside the United States. The key point of that guidance was that swaps trading within the ā€œguaranteedā€ foreign subsidiaries of U.S. bank holding company swaps dealers were subject to all of Dodd-Frankā€™s swaps regulations wherever in the world those subsidiariesā€™ swaps were executed. At that time, the standardized industry swaps agreement contemplated that, inter alia, U.S. bank holding company swaps dealersā€™ foreign subsidiaries would be ā€œguaranteedā€ by their corporate parent, as was true since 1992. In August 2013, without notifying the CFTC, the principal U.S. bank holding company swaps dealer trade association privately circulated to its members standard contractual language that would, for the first time, ā€œdeguaranteeā€ their foreign subsidiaries. By relying only on the obscure footnote 563 of the CFTC guidanceā€™s 662 footnotes, the trade association assured its swaps dealer members that the newly deguaranteed foreign subsidiaries could (if they so chose) no longer be subject to Dodd-Frank. As a result, it has been reported (and it also has been understood by many experts within the swaps industry) that a substantial portion of the U.S. swaps market has shifted from the large U.S. bank holding companies swaps dealers and their U.S. affiliates to their newly deguaranteed ā€œforeignā€ subsidiaries, with the attendant claim by these huge big U.S. bank swaps dealers that Dodd-Frank swaps regulation would not apply to these transactions. The CFTC also soon discovered that these huge U.S. bank holding company swaps dealers were ā€œarranging, negotiating, and executingā€ (ā€œANEā€) these swaps in the United States with U.S. bank personnel and, only after execution in the U.S., were these swaps formally ā€œassignedā€ to the U.S. banksā€™ newly ā€œdeguaranteedā€ foreign subsidiaries with the accompanying claim that these swaps, even though executed in the U.S., were not covered by Dodd-Frank. In October 2016, the CFTC proposed a rule that would have closed the ā€œdeguaranteeā€ and ā€œANEā€ loopholes completely. However, because it usually takes at least a year to finalize a ā€œproposedā€ rule, this proposed rule closing the loopholes in question was not finalized prior to the inauguration of President Trump. All indications are that it will never be finalized during a Trump Administration. Thus, in the shadow of the recent tenth anniversary of the Lehman failure, there is an understanding among many market regulators and swaps trading experts that large portions of the swaps market have moved from U.S. bank holding company swaps dealers and their U.S. affiliates to their newly deguaranteed foreign affiliates where Dodd- Frank swaps regulation is not being followed. However, what has not moved abroad is the very real obligation of the lender of last resort to rescue these U.S. swaps dealer bank holding companies if they fail because of poorly regulated swaps in their deguaranteed foreign subsidiaries, i.e., the U.S. taxpayer. While relief is unlikely to be forthcoming from the Trump Administration or the Republican-controlled Senate, some other means will have to be found to avert another multi-trillion-dollar bank bailout and/or a financial calamity caused by poorly regulated swaps on the books of big U.S. banks. This paper notes that the relevant statutory framework affords state attorneys general and state financial regulators the right to bring so-called ā€œparens patriaeā€ actions in federal district court to enforce, inter alia, Dodd- Frank on behalf of a stateā€™s citizens. That kind of litigation to enforce the statuteā€™s extraterritorial provisions is now badly needed

    A connectome and analysis of the adult Drosophila central brain.

    The neural circuits responsible for animal behavior remain largely unknown. We summarize new methods and present the circuitry of a large fraction of the brain of the fruit fly Drosophila melanogaster. Improved methods include new procedures to prepare, image, align, segment, find synapses in, and proofread such large data sets. We define cell types, refine computational compartments, and provide an exhaustive atlas of cell examples and types, many of them novel. We provide detailed circuits consisting of neurons and their chemical synapses for most of the central brain. We make the data public and simplify access, reducing the effort needed to answer circuit questions, and provide procedures linking the neurons defined by our analysis with genetic reagents. Biologically, we examine distributions of connection strengths, neural motifs on different scales, electrical consequences of compartmentalization, and evidence that maximizing packing density is an important criterion in the evolution of the fly's brain

    Discovery of the dendrophylliid scleractinian Heteropsammia cochlea (Spengler, 1781) in Halimeda bioherms of the Northern Great Barrier Reef

    Halimeda bioherms on the Northern Great Barrier Reef (GBR) extend for over 6000 km2. To explore the ecological and biogeographical importance of these bioherms was one of the aims of a recent voyage on the Research Vessel (RV) Investigator. Through the use of underwater images and habitat sampling, we found populations of Heteropsammia cochlea (Spengler, 1781) living in the bioherms. The scleractinian coral genus Heteropsammia (Dendrophylliidae) is a group of solitary, apozooxanthellate, single-polyp corals with a widespread distribution in tropical and sub-tropical regions. Populations of H. cochlea were observed with individuals dispersed on open-sand habitat and among patches of Halimeda at 30ā€“40Ā m water depth in mean densities of 89 and 29 corals per m2, respectively. Fluorescence microscopy was used to assess the presence of zooxanthellae, indicating that they are actively photosynthesising at these depths. These are the first observations of H. cochlea in association with the Halimeda bioherms on the Northern GBR.</p
