Distributed Information Services in Physics
No full textThe concept of distributed information services maintained by a distributed work force for scientific information is described. Realizations and experiences for Physics (since 1995), Marine Sciences, and dissertation theses in physics are presented. Technically the information is gathered from the local web servers of the worldwide distributed research institutes and departments, by distributed Harvest-gatherers, under the control of national learned societies or regional other institutions. Queries are answered by a network of mirrors of Harvest-brokers. For PhysNet, a Charter sets the rules to assure a noncommercial, free full-text access service, under the control of the set of national national learned societies involved, but unbiased to any single one
A Nanopower 95.6% Efficiency Voltage Regulator with Adaptive Supply-Switching for Energy Harvesting Applications
No full textA nanopower highly efficient low-dropout (LDO) regulator for energy harvesting (EH) applications is presented in this paper. The LDO is fully autonomous with a bandgap reference (BGR) featuring a novel bandgap supply-switching (SS) topology, an over-voltage protection (OVP), a under-voltage lockout (UVLO) and control block to obtain stable output and robust cold-start. The system provides configurable voltage supply (1.1 \sim2V) for potential loads, while consuming as low as 66 nW power. The entire system achieves a peak power efficiency of 95.6% at Vout=2V and I-{\iota-{oad}}=100\muA.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Electronic Instrumentatio
Rethinking Online Action Detection in Untrimmed Videos: A Novel Online Evaluation Protocol
No full textThe Online Action Detection (OAD) problem needs to be revisited. Unlike traditional offline action detection approaches, where the evaluation metrics are clear and well established, in the OAD setting we find very few works and no consensus on the evaluation protocols to be used. In this work we propose to rethink the OAD scenario, clearly defining the problem itself and the main characteristics that the models which are considered online must comply with. We also introduce a novel metric: the Instantaneous Accuracy ( ). This new metric exhibits an online nature and solves most of the limitations of the previous metrics. We conduct a thorough experimental evaluation on 3 challenging datasets, where the performance of various baseline methods is compared to that of the state-of-the-art. Our results confirm the problems of the previous evaluation protocols, and suggest that an IA-based protocol is more adequate to the online scenario. The baselines models and a development kit with the novel evaluation protocol will be made publicly available.greenPattern Recognition and Bioinformatic
Spring EngAGEment: An Interprofessional Collaboration to Enhance Community Interaction and University Education
No full textPurpose
Interprofessional education and practices are increasingly recognized as vital to addressing complex health needs, including individuals living with Alzheimer\u27s disease or other associated dementias (AD/OAD). An innovative approach to meet this need is to create a meaningful engagement experience, Spring EngAGEment, following a multidisciplinary patient-centered model to serve individuals with AD/OAD and their care partners in the community and to offer new interprofessional collaboration opportunities for college students and faculty across disciplines in nursing, recreation, and speech-language pathology. The Spring EngAGEment program was developed by lead undergraduate students in an outcome-based program planning course from the Department of Recreation, Parks & Leisure Services and implemented by student volunteers and faculty across the disciplines with ongoing mentorship from the author team and feedback from the local ACT on Alzheimer\u27s team. The program offered community resource booths, gardening, music therapy, and physical activity education as a way to inform individuals with AD/OAD and their care partners on available community resources, increase their mental outlook, and help reduce their isolation and stress. Conclusions
This interprofessional practice/interprofessional education experience not only allowed college students to facilitate collaboration with future health care professionals from a variety of disciplines but also provided the participants living with AD/OAD and their care partners with new ideas and strategies to help adjust to their life changes. Program outcomes from event participants with AD/OAD and student volunteers were reported. Lessons identified by the author team are discussed
Societal Discrimination and its impact on Live Music Industry in Pakistan
No full textThe global live music industry has become a significant income resource for national economies and artists associated with the music industry. Unfortunately, the live music industry could not contribute to the national economy and support artists in Pakistan due to certain factors. This study was carried out to investigate the influences of factors such as societal discrimination (SD) and lack of government support (LGS) on the live music industry in Pakistan. The online questionnaire was designed to collect data and collected data from 203 artists was analyzed by employing SPSS techniques. The results of this study showed that both factors had an adverse impact on the live music industry
Revealing the Barriers and Facilitators Impacting Uptake of Open-Source Software and Open-Access Data Within Built- Environment Professional Practice Using Actor-Network Theory
No full text© 2025 Graham InglertThis thesis investigates the barriers and the facilitators impacting uptake of Free/Libre Open- Source Software (FLOSS) and Open-Access Data (OAD) among built-environment professionals in Greater Melbourne, Victoria, Australia. By adapting Actor-Network Theory (ANT), this research examines software uptake in professional practice not as a product of individual logical choice but rather as a series of negotiations among heterogeneous actors within professional networks. The study responds to critical concerns of the Smart City’s reliance on proprietary technologies by exploring how Open-Source principles might redistribute agency and uphold democracy within professional practice. Through twelve semi-structured interviews with urban planners, designers, engineers, and geospatial analysts across public, private and educational sectors, this exploratory qualitative research employs an adapted ANT methodology that identifies the key domains shaping FLOSS and OAD uptake within professional networks. The outcome reveals that for the uptake of FLOSS instrumentation there must be a successful formation of networks of social actors. The major elements opposing this network formation was found to include IT departments, crystallised workflows within proprietary software, the expectation for specific file formats, concerns of credibility that could be derived in incorporating alternative instruments and the segregation of professional roles within contemporary practice. The most powerful facilitators identified included ‘Vanguard Actors’, informal networks of peer support and modular plugin ecosystems that expanded the appeal of FLOSS and OAD in practice. This minor thesis identifies and makes recommendations for strategies to construct durable FLOSS networks by utilising collaboration of institutional organisations and social actors. To the best knowledge of the author, this study provides the first systematic network analysis of FLOSS and OAD adoption within professional built-environment practice
AGU hydrology days 2015
No full text2015 annual AGU hydrology days was held at Colorado State University on March 23 - March 25, 2015.Includes bibliographical references.For the joint sustainability of agriculture and other economic sectors, agriculture water use will need to become more efficient and productive in the future. And, indeed, there are opportunities in the agriculture sector for water conservation by utilizing modern technology such as the drip irrigation and the practice of deficit irrigation. A collaborative research effort will be undertaken by the United Water and Sanitation District, the Platte River Water Development Authority, the 70 Ranch, Netafim, and the Colorado State University. The overall goal of the collaborative research is to generate knowledge for preserving the strong agricultural economy of the South Platte Valley in Eastern Colorado, while at the same time freeing up some water for other societal needs. This will be done by establishing a research/extension station in the region and conducting experimentation on more efficient irrigation technologies such as subsurface drip irrigation and deficit irrigation. The underlying premise is that by following such crop and water management practices, the farmers can increase their net economic returns. The planning horizon to achieve this long-term goal is about 15-20 years, but some practical answers to specific research questions should be available in early phases. This document briefly discusses a research proposal focused on the initial stage of the above study (first two years). The aim is to examine: (a) the feasibility of drip irrigation and (b) the effect of deficit irrigation on some of the drought resistant local crops in order to define the feasibility of deficit irrigation for farmers. Field work and data collection starts on summer 2015
AGU hydrology days 2016
No full text2016 annual AGU hydrology days was held at Colorado State University on March 21 - March 23, 2016.Includes bibliographical references.Subsurface drip irrigation (SDI) is a type of drip irrigation with buried pipe lines so that water is applied directly to the root zone and under soil surface. SDI systems have high application efficiency but need high technology for installation and are, thus, costly. SDI is relatively new to Colorado and mainly used for vegetables. As a costly system its use is still limited. However, it is compatible with automation so that timing and volume of water application can be controlled with great precision. SDI provides a good opportunity in times of water scarcity when deficit irrigation is inevitable. Drought in a river basin increases the value of water and farmers can benefit from selling part of their water to municipal and industrial water users. The remaining water is normally not enough for fully irrigating the crops so this practice is called deficit irrigation. Reduced yield due to water deficit can be predicted using crop water production functions; however, it is essential to control water application precisely so that the predicted yield is guaranteed. This paper will explore the opportunities that SDI provides for practice of deficit irrigation
The effects of cost sharing in the Medicare Part D benefit on branded and generic oral anti-diabetic adherence
No full textThesis (Ph.D.)--Boston University
PLEASE NOTE: Boston University Libraries did not receive an Authorization To Manage form for this thesis or dissertation. It is therefore not openly accessible, though it may be available by request. If you are the author or principal advisor of this work and would like to request open access for it, please contact us at [email protected]. Thank you.This dissertation includes three papers on oral anti-diabetic (OAD) medication adherence and the Medicare Part D benefit. The data source for all analyses is the IMS Health Longitudinal Prescription database, which contains patient de-identified prescription data from computerized pharmacy records and reflects over 60% of the prescriptions filled in the United States. The analytic samples culled from this database consist of elderly diabetes patients with Medicare Part D standard (non-LIS), low-income-subsidy (LIS), or commercial prescription medication coverage. I compare non-LIS patients, whose coverage contains a gap (also known as the "donut hole"), to patients with LIS or commercial coverage and no gap.
The first paper tests the hypothesis that diabetes patients with non-LIS coverage are selective in their use of oral anti-diabetic (OAD) medications, and less likely to be adherent to branded-only class OADs. I use logistic regression to model the effects of this coverage on within-class OAD adherence, comparing non-LIS to propensity-matched LIS and commercially covered patients. I find evidence that the Part D benefit is associated with cost-related non-adherence in branded-only, but not primarily generic, class OADs.
In the second paper, I examine the effects of increasing generic medication use on concurrent adherence evaluations. I use the same logistic model to compare three recognized but different concurrent adherence outcome measures. The measures generate estimates of the effects of Part D coverage on adherence that differ in significance and magnitude and that vary further, depending on the distribution of prices in the underlying patient sample.
In the third paper, I test the hypothesis that patients decrease more costly branded OAD use in anticipation of the Part D coverage gap. Using a difference-in-difference design, I use GEE via proc genmod to estimate the effects of the gap on within-class OAD adherence over the coverage year. Compared to LIS and commercially covered, non-LIS patients have increasingly lower odds of adherence to branded-only class OADs starting in the first month of the coverage year. These findings provide evidence of forward-looking behavior, and suggest further that deductibles and co-payments, Part D cost sharing components in addition to the gap, adversely affect adherence
A biodiversity dataset graph: Biological Associations in TaxonWorks hash://sha256/a4d651aac5220487835e6178511886e98b845b2d98cb7c5447fb2b042e0654d2 hash://md5/849edbe55e31e54ea5cdaba0188c5655
No full textThe intended use of this archive is to facilitate (meta-)analysis of Biological Associations captured in TaxonWorks [1]. TaxonWorks is an integrated web-based workbench for taxonomists and biodiversity scientists. It allows you to capture, organize, and enrich your data; share it with collaborators; and package it for analysis and publication.
This dataset provides versioned snapshots of the TaxonWorks network as tracked by Preston [2,3,4] between 2023-08-16 and 2023-08-16 using:
preston track -u https://sfg.taxonworks.org
. In addition, this dataset provides a processed version of the biological associations using the "preston tw-stream" command as generated by the following bash script:
#!/bin/bash
#
# Generates GloBI interaction JSON Lines from provided provenance log as generated by preston tw-stream.
#
/usr/local/bin/preston cat hash://sha256/ff5e709305e593c87711e897b6341b94e775e2f312aa6d4ae5ed6120babd6f5e\
| /usr/local/bin/preston tw-stream
The script itself was executed using:
cat transform.sh | preston bash
The execution of this transform.sh script (with content id hash://sha256/ea6c131a7436c9080b9380c7712dd32654a564fbb6f0568ff97bd7a8f28337a4), as well as their results, is captured within this datasets also. A rdf/quads formatted machine readable version of the workflow execution description can be found via:
preston cat hash://sha256/ab7550368905e7c919e70a306efbb97719a1edbba2cfe4c4515f635ebc0be4bb
And, the resulting JSON Lines file has content id (or signature) hash://sha256/93c748c9e88a8c221f4d9cf4de37f0506d8427a4383cf1ee2078983cdeb31a14 and is also included as interactions.json to facilitate access.
The first json record can be generated using:

In this example, a claim is made that, according to https://sfg.taxonworks.org/api/v1/sources/49013 [6] Eupelmus (a parasitic wasp) has a primary host in the family of Agromyzidae (leaf-miner flies).
In total, 138,246 such claims can be found in the generated resource with alias interactions.json and content id starting with hash://sha256/93c748c... .
In addition, the archive consists of 256 individual parts (e.g., preston-00.tar.gz, preston-01.tar.gz, ...) to allow for parallel file downloads. The archive contains three types of files: index files, provenance logs and data files. In addition, index files have been individually included in this dataset publication to facilitate remote access. Index files provide a way to links provenance files in time to establish a versioning mechanism. Provenance files describe how, when, what and where the TaxonWorks content was retrieved. For more information, please visit https://preston.guoda.bio or https://doi.org/10.5281/zenodo.1410543 .
To retrieve and verify the downloaded TaxonWorks biodiversity dataset graph, first concatenate all the downloaded preston-*.tar.gz files (e.g., cat preston-*.tar.gz > preston.tar.gz). Then, extract the archives into a "data" folder. Alternatively, you can use the preston[2] command-line tool to "clone" this dataset using:
java -jar preston.jar clone --remote https://zenodo.org/record/8253729/files
After that, verify the index of the archive by reproducing the following provenance log history:
java -jar preston.jar history --log tsv
