Extraction of Recipe Steps from Scientific Papers: The Nanomaterials Synthesis Domain

The overall goal of this research is to effectively extract steps for performing a specified procedure from published text descriptions, producing a recipe listing the materials, operations, and conditions required to perform the procedure. For example, if the procedure is to create a nanomaterial, and relevant source text consists of peer-reviewed scientific publications, a recipe should include raw materials and unit operations, among other specifications of a chemical engineering process. This project focuses on developing performance measures to evaluate recipe steps, by gauging their correctness, completeness, and non-redundancy. This is done by comparing manually annotated documents that conveyed desired results to automatically extracted steps, and finding any discrepancies to improve on how recipes are organized. Each annotator manually compiles a set of reference recipes to compare against automatically extracted ones, tallies errors based on a standard developed in collaboration with subject matter experts, then audits a different set of scientific papers marked up by another annotator. This auditing process allows a group of annotators to mutually check each other\u27s work to ensure that recipes are correctly compiled. A corpus of experimental documents was collected using a web crawler from open access web archives. These documents were filtered to determine which ones are scientific papers, ranking them by relevance, and finally, dividing and extracting structured information about the specified ingredients and steps. My main task in this research is to measure the impact of improved extraction rules on the rate of steps correctly captured

Dual Abrikosov vortex between confined charges

We show that the dual Abrikosov vortex between quark and antiquark in Abelian Projected SU(2) gauge theory is insensitive to truncation of all loops except the large monopole cluster noted by Hart and Teper. As the transverse distance increases, the discrepancy decreases, suggesting that the London penetration depth determined by the tail is invariant under the truncation of short loops.Comment: Latex, tar-compressed file, two figures, Lattice 2002 contributed tal

Digital Health Privacy in Active-Aging Settings: Will the Law Let You Age Well?

What is privacy and how are our interpretations of it changing with advances in technology? This question, and concerns around potentially violating a person’s right to privacy, have been emerging across industries around the world. Senior living providers have increased their exposure to privacy risks with the shift to implementing sensors throughout their communities. Typically located in digital health devices that can be worn on the body or placed in the environment, these sensors are capable of collecting and tracking data relevant to a person’s health and well-being on a continuous monitoring basis.There are privacy laws and a growing public awareness that this type of 24/7 surveillance—and the unprecedented detailed level of data it generates—should be accompanied by measures that support personal data protection. It is important to note that these privacy risks also apply outside the housing context. For example, seniors centers that use (or are planning to use) sensors to monitor participants and collect the generated data are similarly exposed.Benefits of sensor surveillance and monitoring of personal data must be balanced with safeguarding protections, especially for cognitively impaired older adults

Towards an ultra‐low‐power low‐cost wireless visual sensor node for fine‐grain detection of forest fires

Advances in electronics, sensor technologies, embedded hardware and software are boosting the application scenarios of wireless sensor networks. Specifically, the incorporation of visual capabilities into the nodes means a milestone, and a challenge, in terms of the amount of information sensed and processed by these networks. The scarcity of resources – power, processing and memory – imposes strong restrictions on the vision hardware and algorithms suitable for implementation at the nodes. Both, hardware and algorithms must be adapted to the particular characteristics of the targeted application. This permits to achieve the required performance at lower energy and computational cost. We have followed this approach when addressing the detection of forest fires by means of wireless visual sensor networks. From the development of a smoke detection algorithm down to the design of a low‐power smart imager, every step along the way has been influenced by the objective of reducing power consumption and computational resources as much as possible. Of course, reliability and robustness against false alarms have also been crucial requirements demanded by this specific application. All in all, we summarize in this paper our experience in this topic. In addition to a prototype vision system based on a full‐custom smart imager, we also report results from a vision system based on ultra‐low‐power low‐cost commercial imagers with a resolution of 30×30 pixels. Even for this small number of pixels, we have been able to detect smoke at around 100 meters away without false alarms. For such tiny images, smoke is simply a moving grey stain within a blurry scene, but it features a particular spatio‐temporal dynamics. As described in the manuscript, the key point to succeed with so low resolution thus falls on the adequate encoding of that dynamics at algorithm levelMinisterio de Economía y Competitividad TEC2012‐38921‐C02, IPT‐2011‐1625‐430000, IPC‐ 20111009 CDTIJunta de Andalucía TIC 2338‐201

This ichnotaxon consists of horizontal, sinuous or meandering trace fossils with a laminated backfill and two parallel strings located at the base. Abundant body fossils attributed to Brisaster iheringi occur in close association to these trace fossils. The echinoids are very well preserved, and most of the specimens have some areas with their spines attached in life position. In particular, preservation of the subanal tufts of spines, associated to isopores (which are interpreted as being associated to funnel building tube feet), supports the interpretation that these organisms are the producers of Scolicia isp. A shaft connecting the burrow with the sediment-water interface was not observed in vertical sections of the excavations, although on bedding plane surfaces, some small circular tube outlets are recognized. However, the great diversity and abundance of ichnofossils co-occurring in these deposits may preclude adequate identification of vertical structures. These deposits provide an excellent opportunity to integrate trace fossil data, body fossil information and observations from modern analogues in order to perform a morpho-functional analysis of Scolicia.Scolicia is one of the most conspicuous trace fossils in lower shoreface deposits of the Miocene Chenque Formation of Patagonia, Argentina.

Metal dyshomeostasis in the substantia nigra of patients with Parkinson's disease or multiple sclerosis

Abnormal metal distribution in vulnerable brain regions is involved in the pathogenesis of most neurodegenerative diseases, suggesting common molecular mechanisms of metal dyshomeostasis. This study aimed to compare the intra- and extra-neuronal metal content and the expression of proteins related to metal homeostasis in the substantia nigra (SN) from patients with Parkinson's disease (PD), multiple sclerosis (MS), and control subjects. Metal quantification was performed via ion-beam micro-analysis in neuromelanin-positive neurons and the surrounding tissue. For proteomic analysis, SN tissue lysates were analyzed on a nanoflow chromatography system hyphenated to a hybrid triple-quadrupole time-of-flight mass spectrometer. We found increased amounts of iron in neuromelanin-positive neurons and surrounding tissue in patients with PD and MS compared to controls (4- to 5-fold higher) that, however, also showed large inter-individual variations. Copper content was systematically lower (-2.4-fold) in neuromelanin-positive neurons of PD patients compared with controls, whereas it remained unchanged in MS. Protein-protein interaction (PPI) network analyses revealed clusters related to Fe and Cu homeostasis among PD-deregulated proteins. An enrichment for the term metal homeostasis was observed for MS-deregulated proteins. Important deregulated hub proteins included hemopexin and transferrin in PD, and calreticulin and ferredoxin reductase in MS. Our findings show that PD and MS share commonalities in terms of iron accumulation in the SN. Concomitant proteomics experiments revealed PPI networks related to metal homeostasis, substantiating the results of metal quantification
