Exploring the material culture of medical artifacts in the Oblate Collection

How can we explore object biographies when a collection has relied heavily on the donor’s narrative? This article uses three artifacts to explore the history of Ingenium’s ‘Oblate Collection’, a group of 282 medical artifacts used at L’Hôpital de L’Assomption in Grand Falls, New Brunswick, on the land of the Wolastoqiyik people. The hospital was opened in 1952 by the newly founded Secular Institute, a branch of the Oblate Missionaries of Mary Immaculate who ran 48 residential schools across Canada. Our catalogue information on the ‘Oblate Collection’ relies largely on the narrative from the donors themselves, primarily, two documents written by one of the nurses, Fabienne Rinfret, who elaborates on life working in the hospital and how the artifacts were used by the staff. Our files lack stories of patient experiences or a fuller, more inclusive sense of their local context including connections to Indigenous people and land. In order to tell a more well-rounded story of the collection, and fill out missing historical dimensions we can also look to the artifacts themselves through material culture readings and further research. Additional work with this collection will hopefully bring in more ways of knowing and different perspectives on these artifacts.

A dataset of the distribution and characteristics of debris flows along the National Highway 318 in the Sino-Nepalese transport corridor (2022)

Due to the unique geographical and geological conditions in the Sino-Nepal transportation corridor, there is a lack of reliable and comprehensive data on debris flow distribution data in the region. This dataset is compiled based on early identification of debris flows and field surveys, integrating Digital Elevation Models (DEM) and geological maps. It provides a catalog and detailed feature information of debris flows within the corridor along the National Highway 318 between China and Nepal from 1990 to 2022. Precipitation and temperature parameters are derived from 30 years (1980–2009) of interpolated data from national meteorological stations. Fault distribution information is sourced from the 1:50,000 digital geological maps published by the China Geological Survey. Terrain information is obtained from NASA's Shuttle Radar Topography Mission (SRTM) data, which provides a global DEM at a resolution of 12.5 m. Within the geographical coordinates of 28.0°–29.4°N and 85.1°–88.9°E, a total of 255 debris flow records have been extracted, covering an area of 1660.73 km². We primarily employed hydrological analysis methods in ArcGIS for the extraction of debris flow basins. Considering the limitations in DEM accuracy, we made necessary manual corrections with reference to Google Earth imagery. The dataset comprises three files: a vector file depicting the main distribution range of debris flows along the National Highway 318 in the Sino-Nepalese transport corridor; a vector file containing the catalog of debris flows; and a document detailing the parameters and characteristics of the debris flows.The dataset has undergone on-site field surveys and confirmation to ensure its reliability. Therefore, it can serve as a foundational dataset applicable to debris flow studies in the region.

Harmonic analysis of discrete tracers of large-scale structure

It is commonplace in cosmology to analyze fields projected onto the celestial sphere, and in particular density fields that are defined by a set of points e.g. galaxies. When performing an harmonic-space analysis of such data (e.g. an angular power spectrum) using a pixelized map one has to deal with aliasing of small-scale power and pixel window functions. We compare and contrast the approaches to this problem taken in the cosmic microwave background and large-scale structure communities, and advocate for a direct approach that avoids pixelization. We describe a method for performing a pseudo-spectrum analysis of a galaxy data set and show that it can be implemented efficiently using well-known algorithms for special functions that are suited to acceleration by graphics processing units (GPUs). The method returns the same spectra as the more traditional map-based approach if in the latter the number of pixels is taken to be sufficiently large and the mask is well sampled. The method is readily generalizable to cross-spectra and higher-order functions. It also provides a convenient route for distributing the information in a galaxy catalog directly in harmonic space, as a complement to releasing the configuration-space positions and weights, and a route to spectral apodization. We make public a code enabling the application of our method to existing and upcoming datasets.

Geographic Barriers to Indexing: Examining Appalachia

The objective of this study was to examine the accuracy of indexing for “Appalachian Region”[Mesh]. Researchers performed a search in PubMed for articles published in 2019 using “Appalachian Region”[Mesh] or “Appalachia” or “Appalachian” in the title or abstract. Only 17.88% of the articles retrieved by the search were about Appalachia according to the ARC definition. Most articles retrieved appeared because they were indexed with state terms that were included as part of the mesh term. Database indexing and searching transparency is of growing importance as indexers rely increasingly on automated systems to catalog information and publications.

Attenuation proxy hidden in surface brightness – colour diagrams

Aims. Large future sky surveys, such as the Legacy Survey of Space and Time (LSST), will provide optical photometry for billions of objects. Reliable estimation of the physical properties of galaxies requires information about dust attenuation, which is usually derived from ultraviolet (UV) and infrared (IR) data. This paper aims to construct a proxy for the far-UV (FUV) attenuation (AFUVp) from the optical data alone, enabling the rapid estimation of the star formation rate (SFR) for galaxies that lack UV or IR data. This will accelerate and improve the estimation of key physical properties of billions of LSST–like observed galaxies (observed in the optical bands only). Methods. To mimic LSST observations, we used the deep panchromatic optical coverage of the Sloan Digital Sky Survey (SDSS) Photometric Catalogue, Data Release 12, complemented by the estimated physical properties for the SDSS galaxies from the GALEX-SDSS-WISE Legacy Catalog (GSWLC) and inclination information obtained from the SDSS Data Release 7. We restricted our sample to the 0.025–0.1 spectroscopic redshift range and investigated relations among surface brightness, colours, and dust attenuation in the FUV range for star-forming galaxies obtained from the spectral energy distribution (SED). Results. Dust attenuation is best correlated with colour measured between u and r bands (u − r) and the surface brightness in the u band (μu). We provide a dust attenuation proxy for galaxies on the star-forming main sequence. This relation can be used for the LSST or any other type of broadband optical survey. The mean ratio between the catalogue values of SFRs and those estimated using optical-only SDSS data with the AFUVp prior calculated as ΔSFR = log(SFRthis work/SFRGSWLC) is found to be less than 0.1 dex, while runs without priors result in an SFR overestimation larger than 0.3 dex. The presence or absence of the AFUVp has a negligible influence on the stellar mass (Mstar) estimation (with ΔMstar in the range from 0 to −0.15 dex). Conclusions. We note that AFUVp is reliable for low-redshift main sequence galaxies. Forthcoming deep optical observations of the LSST Deep Drilling Fields, which also have multi-wavelength data, will enable one to calibrate the obtained relation for higher redshift galaxies and, possibly, extend the study towards other types of galaxies, such as early-type galaxies off the main sequence.

Joint cosmological and gravitational-wave population inference using dark sirens and galaxy catalogues

In the absence of numerous gravitational-wave detections with confirmed electromagnetic counterparts, the “dark siren” method has emerged as a leading technique of gravitational-wave cosmology. The method allows redshift information of such events to be inferred statistically from a catalogue of potential host galaxies. Due to selection effects, dark siren analyses necessarily depend on the mass distribution of compact objects and the evolution of their merger rate with redshift. Informative priors on these quantities will impact the inferred posterior constraints on the Hubble constant (H 0). It is thus crucial to vary these unknown distributions during an H 0 inference. This was not possible in earlier analyses due to the high computational cost, restricting them to either excluding galaxy catalogue information, or fixing the gravitational-wave population mass distribution and risking introducing bias to the H 0 measurement. This paper introduces a significantly enhanced version of the Python package gwcosmo, which allows joint estimation of cosmological and compact binary population parameters. This thereby ensures the analysis is now robust to a major source of potential bias. The gravitational-wave events from the Third Gravitational-Wave Transient Catalogue are reanalysed with the GLADE+ galaxy catalogue, and an updated, more reliable measurement of H 0 = 69+12 -7 km s-1 Mpc-1 is found (maximum a posteriori probability and 68% highest density interval). This improved method will enable cosmological analyses with future gravitational-wave detections to make full use of the information available (both from galaxy catalogues and the compact binary population itself), leading to promising new independent bounds on the Hubble constant.

Pengembangan Aplikasi Bebas Pustaka Mandiri dengan Menerapakan Model Integrasi Sistem dan Interoperabilitas

The Library Free Certificate (SKBP) is a graduation requirement that is applied in many universities, one of which is the Andalas University Library. To make it easier for students to get SKBP, the library has used the Bebas Pustaka Mandiri Application. This application is web-based and can be accessed online. Its development applies the interoperability model by integrating it with other related applications, namely: the Library Catalog Information System, and Graduation Information System. This application allows students to propose the issuance of SKBP independently without the need to come to the library. This study aims to test the performance and measure the benefits of implementing the Aplikasi Mandiri in overcoming various problems in SKBP management. The method used is descriptive qualitative, and data collection is done through direct observation, interviews, and documentation. The results of this study indicate that the application of the concept of interoperability utilizing web service technology has succeeded in supporting the process of exchanging and sharing data between the applications involved properly and smoothly. This study concludes that the use of the Aplikasi Mandiri in managing SKBP has succeeded in shortening the issuance time of SKBP and cutting bureaucratic lines in the library. The time efficiency offered contributes to increasing the productivity of students and officers involved.

The preparatory process of the 2023 Mw 7.8 Türkiye earthquake

To verify the existence of a preparatory process for the 6 February 2023, Mw 7.8 Kahramanmaraş earthquake, southern Türkiye, we analyze the temporal evolution of seismic catalog information for ~ 7500 earthquakes with magnitudes ML ≥ 1.5, which occurred along the main segments of the East Anatolian Fault (EAF) since 2014. We find the EAF fault segments showing different temporal patterns in the proportion of nonclustered seismicity, which we interpret as temporal variation of coupling. We also study the evolution of the b-value, fractal dimension and energy rate. These seismic features show for the Amanos and Pazarcık fault segments a long-term trend during the period 2020–2022 that might correspond to a quiescence phase. The latter is followed by a change in earthquakes clustering and characteristics that starts about eight months before the Mw 7.8 Kahramanmaraş event. Our observations confirm the existence of a long-lasting preparatory phase for the 2023, Mw 7.8 Kahramanmaraş earthquake and can stimulate new investigations on the East Anatolian Fault mechanic. Intercepting when a fault starts deviating from its steady behavior, might be the key for identifying the preparatory phase of large earthquakes and mitigate seismic risk.

Detecting the Preparatory Phase of Induced Earthquakes at The Geysers (California) Using K‐Means Clustering

AbstractThe generation of strong earthquakes is a long‐debated problem in seismology, and its importance is increased by the possible implications for earthquake forecasting. It is hypothesized that the earthquake generation processes are anticipated by several phenomena occurring within a nucleation region. These phenomena, also defined as preparatory processes, load stress on the fault leading it to reach a critical state. In this paper, we investigate the seismicity preceding 19 moderate (Mw ≥ 3.5) earthquakes at The Geysers, Northern California, aiming to verify the existence of a preparatory phase before their occurrence. We apply an unsupervised K‐means clustering technique to analyze time series of physics‐related features extracted from catalog information and estimated for events occurred before the mainshocks. Specifically, we study the temporal evolution of the b‐value from the Gutenberg‐Richter (b), the magnitude of completeness (Mc), the fractal dimension (Dc), the inter‐event time (dt), and the moment rate (). Our analysis shows that out of 19 moderate magnitude events considered, a common preparatory phase for 11 events is clearly identified, plus other five events for which we can guess a preparatory phase but with different characteristics from the previous ones. The latter result confirms that even within the same tectonic context different possible activation behaviors may exist. The duration of the preparatory process ranges between about 16 hr and 4 days. We observe that also for the retrieved preparatory process a decrease in b, Mc, and Dc, and an increase of . Finally, we show a clear correlation between events with a preparation phase and the location of injection's wells, suggesting an important role of fluids in the preparatory process.

On catching the preparatory phase of damaging earthquakes: an example from central Italy

How, when and where large earthquakes are generated remain fundamental unsolved scientific questions. Intercepting when a fault system starts deviating from its steady behavior by monitoring the spatio-temporal evolution and dynamic source properties of micro-to-small earthquakes can have high potential as tool for identifying the preparatory phase of large earthquakes. We analyze the seismic activity that preceded the Mw 6.3 earthquake that hit L’Aquila on 6 April 2009 in central Italy, and we show that the seismic catalog information can be transformed into features allowing us to track in a statistical framework the spatio-temporal evolution of seismicity. Features associated to foreshocks show different patterns from the background seismicity that occurred in the previous years. We show that features ensemble allows to clearly capture the activation phase of the main event. Nonetheless, foreshocks share similar clustering properties of previous seismic sequences not culminating in large earthquakes, and thus generating questions on their use as potential precursor for earthquake sequences prone to evolve into catastrophic sequences.

Comparative Probabilistic Seismic Hazard Analysis for Sakarya

Sakarya province can be significantly affected by earthquakes on the North Anatolian Fault. Earthquake hazard includes some uncertainties. Earthquake catalog data is needed for probabilistic earthquake hazard calculations. In addition to current catalog information, existing attenuation relationships, including earthquake characteristics for the region, should be developed or their suitability checked. For this purpose, an earthquake hazard analysis was carried out for the Serdivan, Erenler, Adapazarı, and Arifiye districts of Sakarya by using the EMME (Earthquake Model of the Middle East Region) data catalog, which was carried out on a global scale and using the ASK14 model from the NGA-West2 equations. CRISIS software was used for analysis. As a result of the study, it was concluded that the evaluation of ground effects in these regions is an essential requirement.

Ecological risk identification and assessment of land remediation project based on GIS technology.

A land remediation project involves the removal of potentially toxic chemicals from a polluted site. Lands abandoned by industry are often contaminated with heavy metals like mercury, lead, chemicals, arsenic, and other toxins like dichlorodiphenyltrichloroethane biphenyls from electronic devices, and volatile organic chemicals (VOCs) from lubricants and chemicals. Risk assessment in environmental settings requires modernized systematic methodologies due to the complexity of today's environmental problems. When people eat, drink, or work in polluted environments, they put their health at risk and may even get cancer. Integrating geospatial information systems (GIS) with pollutant dispersion models makes environmental risk assessment and early warning possible. This research thus presents a GIS-based ecological risk identification and assessment model (GIS-ERIAM) for assessing risk for efficient land rehabilitation. Environmental cleanup sites' catalog information is the source of these details. With satellite imagery, GIS makes it simple to keep an eye on the environment and track the abundance of different types of plants and animals The ecological risk assessment (ERA) model can support recognition and prioritize risk management. By integrating direct and indirect environment interactions, the risk conditions of the whole ecology and its elements have been quantified and demonstrated in the study. The numerical outcomes illustrate that the recommended GIS-ERIAM model improves the performance by 98.9%, risk level prediction by 97.3%, risk classification by 96.4%, and detection of soil degradation ratio of 95.6% compared to other existing methods.

Sustainability in Mechanical Engineering Undergraduate Courses at 100 Universities

AbstractMechanical engineers have an important role in contributing to a more sustainable future. However, the extent that sustainability is currently being integrated into mechanical engineering (ME) curricula is unclear. This research characterized sustainability integration in undergraduate ME courses at 100 universities. Criterion-based selection resulted in a range of institution types and geographic locations (including institutions outside the United States); 93 of the 100 programs were accredited by the Engineering Accreditation Commission (EAC) of ABET. For 90 institutions, the data came from the Association for the Advancement of Sustainability for Higher Education (AASHE) Sustainability Tracking, Assessment & Rating System (STARS). Course catalog information was used for ten additional schools, in addition to comparing catalog data to STARS for ten institutions. Overall, sustainability topics were found in at least one elective or required undergraduate ME course at 83 institutions; only 43 institutions included sustainability in at least one required ME course; 16 institutions offered ten or more ME courses that integrated sustainability topics. Courses with sustainability integration at the greatest number of institutions were thermodynamics, engineering design, introduction to engineering, and heat transfer. Few of these courses appeared to integrate all three sustainability pillars (environmental, social, and economic). Leading institutions for sustainability integrations across the curriculum were identified. This work offers a picture of sustainability incorporation in undergraduate mechanical engineering programs, with the hope of catalyzing greater and more visible sustainability integration in the future.

Involvement of modern information technologies to support the free choice of academic disciplines by students of higher educational institutions

The work is devoted to the implementation of the procedure of free choice of academic disciplines by students of higher educational institutions and the development of means of support for this choice. The main task, which is solved in the work, is the definition of methods and means of information and technological support for the free choice of academic disciplines by students. The purpose of the work is to make the process of choosing disciplines by students more transparent, convenient and understandable. The provisions on the free choice of academic disciplines of the leading institutions of higher education of Ukraine were used as sources of information. The analysis of these provisions made it possible to highlight the main stages of students' free choice of academic disciplines. On the example of the declared procedure for choosing educational disciplines of Kremenchuk Mykhailo Ostrohradskyi National University, the specified stages were detailed. The following structure was used for detailing: stage description; content of the stage; problems and contradictions that arise at the selected stage; proposals and ways of solving identified problems and contradictions. The results of the analysis of the support system for the free choice of educational disciplines are presented in the form of a decision tree. The developed decision tree contains three ways of developing a support system for the student's free choice of educational disciplines, depending on the level of automation of the process. For each development path of the support system, the final products that must be developed to achieve the selected degree of automation of the process of free choice of educational disciplines are indicated. Also, for each path of the development of such a support system, schemes for the involvement of process subjects, which are understood to mean employees of departments and the university administration, have been drawn up. The student is at the top of this process, he is the final consumer, therefore the whole system is aimed at facilitating the procedure of choosing educational disciplines from the student's point of view. Changes to the format of presenting information in the university-wide catalog of free-choice disciplines are also proposed. Key words: individual educational trajectory; disciplines of free choice; information support system; information support; decision tree.

Колекції котових (Felidae) у природничих музеях України та їх значення у поширенні природничих знань

The study is devoted to the analysis of collections of the felid family, which are housed in natural history museums of Ukraine, two academic and eight university. The basics of the modern taxonomy of felids are considered with the vernacular names of tribes, genera and their type species, which is important for the unification of exhibition and catalogue information. For each of the considered museums, four blocks of data are presented: a general summary for the collection, presentation of particularly valuable or unique specimens, and description of the exhibition and scientific collections. The most complete felid collections (in terms of the number of specimens) are housed in the Museum of Nature of Kharkiv University (109 specimens), in the National Museum of Natural History (152 specimens), and in the Zoological Museum of Odesa University (66 specimens); in other collections the amount of material is much smaller (7–36 specimens). The total volume of collections of this family reaches 460 specimens of 21 species of 12 genera (out of 14 living). The examples of materials important for the dissemination of knowledge about this group are given, from folklore to important and interesting scientific facts for the general public. For all species, there is an organised catalogue, classified by tribe, genus, and species (all alphabetically), in which key information about the available specimens is given for each museum. Such information for each species is arranged according to the scheme ‘museum, location, number of samples, collection numbers and types of specimens, date, and collector or preparator.’ The present study is the first such generalisation of zoological collections of Ukraine, the experience of which can be extended to other groups of animals. The development of this study showed a high interest of colleagues in such generalisations, which clearly activate the attention of museum workers, researchers of variability and diversity, potential museum visitors and society to the topic of the selected focus groups and activation of exhibiting and research work in relation to those groups.
