As a memento of my last week of working at LANL, I put together a slide deck that provides an overview of major efforts conducted during the time I was there.
History of F#, and the ML family of languages. Rachel Reese
After I switched from C# (a curly-brace heavy object-oriented language) to F# (a whitespace-sensitive functional language) a few years ago, I started to wonder about the history of programming languages and how they evolve. How does a feature in one language influence a feature in another language -- for instance, where did type providers come from? In this talk, I cover the history of MLs from approximately the dawn of time, eventually focusing on F# specifically.
Text as Data: processing the Hebrew BibleDirk Roorda
The merits of stand-off markup (LAF) versus inline markup (TEI) for processing text as data. Ideas applied to work with the Hebrew Bible, resulting in tools for researchers and end-users.
RDA (Resource Description and Access) is a new standard for describing library resources, designed to replace AACR2. Library staff, including public services, systems personnel, and catalogers, may have heard mention of RDA but not know much about it or how it will change their daily work. You may have many questions. What is RDA? We'll give a very little bit of history and theoretical background. What is this going to mean for catalogers, ILS managers, and users in the near term? What are the future implications, or, why are we doing this? What are the juicy bits of controversy in cataloger-land? And finally, Do we HAVE to? We'll talk for a while, have some activities that get you thinking, and find out your thoughts on RDA.

Individual functional atlasing of the human brain with multitask fMRI data: l...Ana Luísa Pinho
Linking brain systems and mental functions requires accurate descriptions of behavioral tasks and fine demarcations of brain regions. Functional Magnetic Resonance Imaging (fMRI) has opened the possibility to investigate how brain activity is modulated by behavior. However, to date, no data collection has systematically addressed the functional mapping of cognitive mechanisms at a fine spatial scale. Most studies so far are bound to one single task, in which functional responses to a handful of contrasts are analyzed and reported as a group average brain map. The Individual Brain Charting (IBC) project stands for a high-resolution (1.5mm), multi-task fMRI dataset, intended to provide an objective basis for the establishment of a neurocognitive atlas based on the individual mapping of the human brain. This data collection refers to a permanent cohort during performance of a wide variety of tasks across many sessions. Data up to the third release---comprising 28 tasks---are publicly available in the OpenNeuro repository (ds002685). Derived statistical maps from the first and second releases can be found in NeuroVault (id6618) and they amount for 205 canonical contrasts described on the basis of 113 cognitive concepts taken from the Cognitive Atlas. These derivatives reveal all together a comprehensive brain coverage of regions engaged in cognitive processes as well as a successful encoding of the functional networks reported by the original studies. As the dataset becomes larger and the ensuing collection of concepts gets richer, finer subject-specific, cognitive topographies can be extracted from the data. We thus explore this individual-functional-atlasing approach in order to link functional segregation of specialized brain regions to elementary mental functions. Results show that individual topographies---common to all tasks---are consistently mapped within and, to a lesser extent, across participants. Besides, prediction scores associated with the reconstruction of contrasts of one task from the remaining ones reveal the quantitative contribution of each task to these common representations. Yet, scores decreased when subjects were permuted between train and test, confirming that topographies are driven by subject-specific variability. Lastly, we demonstrate how cognitive mapping can benefit from contrasts accumulation, by analyzing the functional fingerprints of a set of individualized regions-of-interest from the language network.

Presentation about reference rot given at the Complexity Science Hub in Vienna, November 2021.
Links to web resources frequently break (link rot), and linked content can change at unpredictable rates (content drift). These dynamics of the Web are detrimental when references to web resources provide evidence or supporting information.
This presentation will report on research that assessed the extent of these problems for links to web resources in scholarly literature, by using three vast corpora of publications and a range of public web archives. It will also describe the Robust Link approach that offers a proactive, uniform, and machine-actionable way to combat link rot and content drift. Finally, it will introduce the Robustify web service and API that was devised to generate links that remain functional over time, paying special attention to challenges related to deploying infrastructure that is required to be long lasting.
Researcher Pod: Scholarly Communication Using the Decentralized WebHerbert Van de Sompel
The presentation provides an overview of the motivation and direction of the Mellon-funded Researcher Pod project that investigates technical aspects of scholarly communication in a decentralized web setting.
Presentation for a workshop about persistent identifiers organized by the Royal Library of The Netherlands and DANS. Highlights the non-trivial commitments required of all parties involved in persistent identifier systems to actually keep links based on persistent identifiers ... err ... persistent.
Various FAIR criteria pertaining to machine interaction with scholarly artifacts can commonly be addressed by means of repository-wide affordances that are uniformly provided for all hosted artifacts rather than through artifact-specific interventions. If various repository platforms provide such affordances in an interoperable manner, devising tools - for both human and machine use - that leverage them becomes easier.
My involvement, over the years, in a range of interoperability efforts has brought the insight that two factors strongly influence adoption: addressing a burning issue and delivering a KISS solution to tackle it. Undoubtedly, FAIR and FAIR DOs are burning issues. FAIR Signposting <https://signposting.org/FAIR/> is an ad-hoc repository interoperability effort that squarely fits in this problem space and that purposely specifies a KISS solution, hoping to inspire wide adoption.
Registration / Certification Interoperability Architecture (overlay peer-review)Herbert Van de Sompel
Presentation for the COAR meeting on Overlay Peer-Review held at INRIA, Paris, France. It provides overall context regarding a scholarly communication system in which the core functions of scholarly communication (registration, certification, awareness, archiving) are implemented in a decoupled manner and whereby each function can simultaneously be fulfilled by different parties, potentially in different ways. It shows how notifications can be used to achieve loosely coupled, point-to-point interoperability in such an environment, zooming in on interoperability between registration and certification aka interoperability between repositories and overlay peer-review services.
Slides used for a keynote presentation at the VIVO 2019 Conference in Podgorica, Montenegro.
Abstract: The invitation to present a keynote at the VIVO Conference and the goal of the VIVO platform, as stated on the DuraSpace site, to create an integrated record of the scholarly work of an organisation reminded me of various efforts that I have been involved in over the past years that had similar goals. EgoSystem (2014) attempted to gather information about postdocs that had left the organisation, leaving little or no contact details behind. Autoload (2017), an operational service, discovers papers by organisational researchers in order to upload them in the institutional repository. myresearch.institute (2018), an experiment that is still in progress, discovers artefacts that researchers deposit in web productivity portals and subsequently archives them. More recently, I have been involved in thinking about the future of NARCIS, a portal that provides an overview of research productivity in The Netherlands. The approach taken in all these efforts share a characteristic motivated by a desire to devise scalable and sustainable solutions: let machines rather than humans do the work. In this talk, I will provide an overview of these efforts, their motivations, the challenges involved, and the nature of success (if any).
Presentation for PIDapalooza 2019, Dublin, Ireland.
The Scholarly Orphans project, funded by the Andrew W. Mellon Foundation, explores technical approaches aimed at capturing and archiving scholarly artifacts that researchers deposit in web productivity portals as a means to collaborate and communicate with their peers. These artifacts are not collected by other frameworks aimed at archiving the scholarly record (e.g., LOCKSS, Portico, Institutional Repositories) and are only incidentally captured by web archives. The project explores an institution-driven approach inspired by web archiving. To demonstrate the ongoing thinking, the project has devised an experimental automated pipeline that continuously discovers, captures, and archives artifacts. These are created by actual researchers who, for the purpose of the experiment, were virtually enlisted in a fictive research institution. A portal at myresearch.institute provides an overview of the artifacts that were discovered and provides access to archived versions stored in both an institutional and a cross-institutional archive. The set-up leverages a range of technologies that share a flavor of persistence: Memento, Memento Tracer, Robust Links, Signposting.
Presentation given at EuropeanaTech 2018 in Rotterdam, The Netherlands. Provides a summary of insights gained from working for about a decade on challenges related to temporal aspects of the web, persistence.
"Scholarly Communication: Deconstruct and Decentralize" was presented at the Fall 2017 Meeting of the Coalition for Networked Information. It explores working towards a Scholarly Commons by applying decentralized web ideas to scholarly communication.
Looks at hyperlinks from the perspective of a managed collection of resources for which link persistence/integrity is considered a quality of service concern. Distinguishes between links into other managed collections and to the web at large. Considers link rot and content drift.
This slide deck provides an overview of proposals to use HTTP Links as a means to address some long standing problems related to scholarly resources on the web.

Presentation for PIDapalooza 2016. PIDs need to be used to achieve their intended persistence. Our research (reported at WWW2016, see http://arxiv.org/1602.09102) found that a disturbing percentage of references to papers that have DOIs actually use the landing page HTTP URI instead of the DOI HTTP URI. The problem is likely related to tools used for collecting references such as bookmarks and reference managers. These select the landing page URI instead of the DOI URI because the former is what's available in the address bar. It can safely be assumed that the same problem exists for other types of PIDs. The net result is that the true potential of PIDs is not realized. In order to ameliorate this problem we propose a Signposting pattern for PIDs (http://signposting.org/identifier/). It consists of adding a Link header to HTTP HEAD/GET responses for all resources identified by a DOI, including the landing page and content resources such as "the PDF" and "the dataset". The Link header contains a link, which points with the "identifier" relation type to the DOI HTTP URI. When such a link is available, tools can automatically discover and use the DOI URI instead of the other URIs (landing page, PDF, dataset) associated with the DOI-identified object.
DBpedia Archive using Memento, Triple Pattern Fragments, and HDTHerbert Van de Sompel
DBpedia is the Linked Data version of Wikipedia. Starting in 2007, several DBpedia dumps have been made available for download. In 2010, the Research Library at the Los Alamos National Laboratory used these dumps to deploy a Memento-compliant DBpedia Archive, in order to demonstrate the applicability and appeal of accessing temporal versions of Linked Data sets using the Memento “Time Travel for the Web” protocol. The archive supported datetime negotiation to access various temporal versions of RDF descriptions of DBpedia subject URIs.
In a recent collaboration with the iMinds Group of Ghent University, the DBpedia Archive received a major overhaul. The initial MongoDB storage approach, which was unable to handle increasingly large DBpedia dumps, was replaced by HDT, the Binary RDF Representation for Publication and Exchange. And, in addition to the existing subject URI access point, Triple Pattern Fragments access, as proposed by the Linked Data Fragments project, was added. This allows datetime negotiation for URIs that identify RDF triples that match subject/predicate/object patterns. To add this powerful capability, native Memento support was added to the Linked Data Fragments Server of Ghent University.
In this talk, we will include a brief refresher of Memento, and will cover Linked Data Fragments, Triple Pattern Fragments, and HDT in more detail. We will share lessons learned from this effort and demo the new DBpedia Archive, which, at this point, holds over 5 billion RDF triples.
These slides go with the paper "Reminiscing About 15 Years of Interoperability Efforts" which is available at http://dx.doi.org/10.1045/november2015-vandesompel
Slides were used for a presentation at the Fall 2015 Membership Meeting of the Coalition for Networked Information.
This presentation looks back at several efforts, conducted in the past fifteen years, aimed at establishing interoperability for web-based scholarly communication. It tries to characterize the perspectives/approaches taken by these efforts and, based upon that, proposes an HATEOS-based approach to interlink scholarly nodes on the web. This was first presented at the Research Data Alliance meeting in Paris, France, September 22 2015.
Extended version of slides presented at the "404/File Not Found" symposium held at Georgetown University on October 24 2014, see http://www.law.georgetown.edu/library/404/ . The presentation provides a brief overview of the link/reference rot problem and then discusses three complimentary strategies to combat it: Pro-actively capturing web resources that are linked from a seed collection; Referencing the captures by means of annotated links; Accessing the captures using Memento infrastructure.
This presentation introduces ResourceSync, a specification aimed to enable web-based synchronization of resources. The specification is the result of a collaboration between NISO and the Open Archives Initiative funded by the Sloan Foundation and JISC. The proposed resource synchronization approach is based on several existing specifications (e.g. Sitemaps, PubSubHubbub, well-known URI) and is aligned with common architectural principles (e.g. REST, follow your nose).
A 15 minute video version of these slides is available at https://www.youtube.com/watch?v=ASQ4jMYytsA
This presentation provides an overview of the Memento "Time Travel for the Web" framework that is aligned with the stable version of the Memento protocol, specified in RFC 7089.
As the scholarly communication system evolves to become natively web-based and starts supporting the communication of a wide variety of objects, the manner in which its essential functions – registration, certification, awareness, archiving - are fulfilled co-evolves. This presentation focuses on the nature of the archival function based on a perspective of the future scholarly communication infrastructure. This presentation, prepared for a meeting in June 2014, is based on and updates a previous one that was prepared for a January 2014 meeting. The latter is available at http://www.slideshare.net/atreloar/scholarly-archiveofthefuture

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.
