Lu-177 DOTATATE Anonymized Patient Datasets
User Collection- Creator:
- Dewaraja, Yuni K and Van, Benjamin J
- Description:
- This collection is comprised of a number of works that collectively represent the imaging studies and information necessary for dosimetric analysis of a patient treated with Lutathera. All works may be used as standalone datasets or in conjunction with the others in this collection depending on the analysis performed. Files are stored using the DICOM standard widely accepted for storage and transmission of medical images and related information. All patient private information has been anonymized using MIM commercial software (MIM Software Inc.). Data from 2 patients, referred to as patient 4 and patient 6, has been provided in this collection and is divided among 6 works as outlined below:, 1) Pre-Therapy Diagnostic Images. Description: Patient diagnostic scans performed prior to Lutathera treatment. Used for identifying lesions and measuring progression. Note that the date of the baseline scan may be several months before the Lutathera treatment and changes in the anatomy are possible. Files: (1) Ga68 Dotatate PET/CT, Either: (1) MRI, (1) standalone diagnostic CT, 2) Planar Whole Body Scans. Description: Planar whole body Lu-177 scans taken at 4 time points within a week after treatment. Two views (Anterior and Posterior) and 3 energy windows (one main window at 208 keV and 2 adjacent scatter windows) are available for each time point. The units of this image is counts. Energy window information, acquisition data/time and duration can be found in DICOM header. Files: (6) individual images at each time point (24 total images per patient) , 3) SPECT/CT Scans. Description: Lu-177 SPECT/CT scans at 4 time points within a week after treatment (same time points as the planar scans). Images were acquired on a Siemens Intevo system and reconstructed using xSPECT Quant. The units of this image is Bq/mL. Information on the reconstruction, acquisition date/time, duration, Lu-177 administration time and activity can be found in the DICOM header. Files: (1) Folder with reconstructed SPECT slices per time point (4 folders total per patient), (1) Folder containing co-registered CT slices per time point (4 folders total per patient), 4) Lesion and Organ Volumes of Interest. Description: DICOM RT structure files containing organ and lesion volumes of interest (VOI) that were defined on the CT of the scan1 SPECT/CT in 3). Organs were defined using semi-automatic tools (atlas based and CNN-based) while lesions were defined manually by a radiologist guided by baseline scans. Only lesions >2 cc were defined. Files: (1) File containing organ contours, (1) File containing lesion contours, 5) Time Integrated Activity Maps. Description: A DICOM file containing the time-integrated activity map over all 4 time points within a week after treatment. This combines the SPECT/CT scans provided in 3) into a single integrated activity map. This map was generated via the MIM MRT Dosimetry package: The 4 time points were registered to the reference SPECT scan (time point 1) using a contour intensity based SPECT alignment and the voxel-level time-activity data was fit using exponential functions. Voxel-level integration was performed to generate the TIA map. The units of this image is Bq/mL * sec. Files: (1) Folder with Time-integrated activity image per patient, and 6) Projection Data and CT based Attenuation Coefficient Maps. Description: SPECT projection data for each of the 4 Lutathera scans taken within a week after treatment is provided in 3 forms: unaltered, Siemens [Reformatted], and Siemens [Advanced]. The difference between the Projections and the [Advanced] Projections is that the [Advanced] consists of uncorrected raw projection data and the other the corrected projection data (e.g. camera uniformity corrections). The [Advanced] projections are used in xSPECT reconstruction (where all corrections are done during the reconstruction), while the other is used in Flash 3D reconstruction. CT-based attenuation coefficient maps (mumaps) are provided for each of the 4 scans taken within a week after treatment. Two methods are provided for each mumap: xSPECT and F3D as the matrix size is different for the 2 cases (256 x 256 for xSPECT and 128 x 128 for Flash3D). Files: (3) Folders containing raw SPECT projections, (2) Folders containing CT attenuation coefficient maps (mumaps)

- Description:
- A new empirical model of the plasmapause location has been developed using density data from the plasma wave receiver onboard the CRRES spacecraft for nearly 1000 orbits. The “plasmapause” is identified here as the innermost sharp gradient in density (change of a factor of 5 in <0.5 L). Such a sharp gradient was observed on 73% of the CRRES inbound and outbound orbits that returned data. The plasmapause location is expressed as a linear function of Kp (previous 12 hour maximum) and local time. The model gives the linear best fit location of the plasmapause as well as the standard deviations of the model parameters.

- Description:
- The study focuses on reconstructing the histories of peat deposition using n-alkane biomarkers in peat cores and associated modern plant communities from four sites around a shallow maar lake in the Changbai Mountains of northeastern China. Peat development patterns in the four sites are not concordant although the sites experienced the same paleoclimate histories. Evidently, lava flows and tephra deposits produced an uneven topography of the volcanogenic lake basin that controls the water depths at the four lake edge locations, thereby leading to differences in peat-forming plant communities and peat deposition among the four sites.

- Description:
- These data are TLA events identified in MACCS magnetometer data throughout 2015. These events are short-timescale (< 60 s), large -amplitude (> 6 nT/s) magnetic disturbances measured at Earth's surface that are analyzed for space weather research purposes. and The events were identified in a year's worth of magnetic field data using an algorithm developed in the MATLAB platform. The algorithm dBdt_main.m can be run using the associated scripts (clean_maccs.m, simple_dbdt.m, extremes1.m, newdbdt.m) to return the events in the 2015_AllEvents.csv file. The substorm onset delays of each event are determined with the onset_delays.m script and the substorm event list 20191127-15-56-substorms.csv (both included).

- Description:
- Conducting quantitative metrics-based performance analysis of first-principles-based global magnetosphere models is an essential step in understanding their capabilities and limitations, and providing scope for improvements in order to enhance their space weather prediction capabilities for a range of solar conditions. In this study, a detailed comparison of the performance of three global magnetohydrodynamic (MHD) models in predicting the Earth’s magnetopause location and ionospheric cross polar cap potential (CPCP) has been presented. Using the Community Coordinated Modeling Center’s Run-on-Request system and extensive database on results from various magnetospheric scenarios simulated for a variety of solar wind conditions, the aforementioned model predictions have been compared for magnetopause standoff distance estimations obtained from six empirical models, and with cross polar cap potential estimations obtained from the Assimmilative Mapping of Ionospheric Electrodynamics (AMIE) Model and the Super Dual Auroral Radar Network (SuperDARN) observations. We have considered a range of events spanning different space weather activity to analyze the performance of these models. Using a fit performance metric analysis for each event, we have quantified the models’ reproducibility of magnetopause standoff distances and CPCP against empirically-predicted observations, and identified salient features that govern the performance characteristics of the modeled magnetospheric and ionospheric quantities.

- Description:
- The purpose of the research is to better understand and approximate the Thurston Set. This project was computational in nature and Python was used to collect our data. The data set contains encoded itineraries that can be used to compute values that are elements of the Thurston Set. A visual approximation of the Thurston Set can be found here ( https://arxiv.org/abs/1402.2008), on the first page Thurston’s own paper. The data can also be used to study the distribution of superattracting beta values within the interval (1, 2] and to explore an analogous Mandelbrot-Julia Correspondence. This research was conducted through the Lab of Geometry at Michigan under the advisement of Harrison Bray during the Fall semester of 2019. , The Python 3.x scripts in this deposit are the exact versions used to created the *.txt files that are in the zip archive. As the project continues, any expansion to the work, such as further analysis or visualization scripts, will be posted to the project's GitHub https://github.com/Tent-Maps-Team/Thurston-Set. Also, a user can reproduce our results and generate bigger datasets on machines with large amounts of memory. , and The data consists of zipper folders representing tent map itinerary orbit lengths. These orbit files can be used to create visualizations, create and explore conjectures such as refining proposed bounds on the Thurston Set and supporting an analogous Mandelbrot-Julia Correspondence. Within these zipped folders are .txt files in CSV format with the naming structure of xx_y of admissible itineraries up to the length indicated by the folder name where xx is the length of the encoded itineraries included. The txt's have a single column and each line(row) is an array representing an encoding of an itinerary. Some of the txt's have been split into multiple parts (whenever there are more than 200 MB of itinerary data) and these txt's have been numbered using the y after the underscore. As we exclude the degenerate tent map (where β = 1), we cannot have orbit length 1 or 2 and this is why the orbits start with length 3 (i.e. start with 3.zip).

- Description:
- This Ph.D. research focuses on two subject areas: experimental and numerical model, which serves as two essential parts of a digital twin. A digital twin contains models of real-world structures and fuses data from observations of the structures and scale experiment to pull the models into better agreement with the real world. Digital twin models have the promise of representing complex marine structures and providing enhanced lifecycle performance and risk forecasts. Experimentally verifying the updating approaches is necessary but rarely performed. Thus, the proposed work is designing an experiment and developing a numerical model updated by the experimental data. The dataset contains all the data collected in the experiment of a four-crack hexagon- shaped specimen is presented, designed to mimic many of the properties of complex degrading marine structural systems, such as crack interaction, component inter- dependence, redundant load path, and non-binary failure.

- Description:
- The Multifaceted Optimization Algorithm (MOA) is a tool for generating corrected empirical model thermospheric densities during geomagnetic storms. It consists of a suite of Python functions that operate around the Spacecraft Orbit Characterization Kit (SpOCK), an orbital propagator developed by Charles D. Bussy-Virat, PhD, Joel Getchius, and Aaron J. Ridley, PhD at the University of Michigan, and it estimates new densities for the NRLMSISE-00 atmospheric model. MOA generates new model densities by estimating modifications to inputs to the NLRMSISE-00 model that minimize the orbit error between modeled spacecraft in SpOCK, and their actual altitudes as described in publicly-available Two-Line Element Sets (TLEs), made available online via Space-track.org. MOA consists of three sub-process: (1) The Area Optimization Algorithm (AROPT), (2) the F10.7 Optimization Algorithm (FOPT), and (3) the Ap Optimization Algorithm (APOPT). AROPT computes the contribution to the drag of the modeled spacecraft due to their varying projected area. FOPT estimates modifications to the 10.7 cm solar radio flux in NRLMSISE-00, and APOPT estimates modifications to the Earth's magnetic activity in NRLMSISE-00. MOA finds these modifications across many spacecraft, and the medians of those modifications are then applied in NLRMSISE-00 along the orbit of another satellite to generate new densities for verification. In this instance, modifications are applied along the orbits of the Swarm spacecraft and compared to Swarm GPS-derived densities.

- Description:
- Traces from single-molecule fluorescence microscopy (SMFM) experiments exhibit photophysical artifacts that typically necessitate human expert screening, which is time-consuming and introduces potential for user-dependent expectation bias. Here, we have used deep learning to develop a rapid, automatic SMFM trace selector, termed AutoSiM, that improves the sensitivity and specificity of an assay for a DNA point mutation based on single-molecule recognition through equilibrium Poisson sampling (SiMREPS). The improved performance of AutoSiM is based on accepting both more true positives and fewer false positives than the conventional approach of hidden Markov modeling (HMM) followed by thresholding. As a second application, the selector was used for automated screening of single-molecule Förster resonance energy transfer (smFRET) data to identify high-quality traces for further analysis, and achieves ~90% concordance with manual selection while requiring less processing time. AutoSiM can be adapted readily to novel datasets, requiring only modest Transfer Learning.

- Description:
- Coastal wetlands intercept significant amounts of nitrogen (N) from watersheds, especially when surrounding land cover is dominated by agriculture and urban development. Through plant uptake, soil immobilization, and denitrification wetlands can remove excess N from flow through water sources and mitigate eutrophication of connected aquatic ecosystems. Excess N can also change plant community composition in wetlands, including communities threatened by invasive species. Understanding how variable hydrology and N loading impact wetland N removal and community composition can help attain desired management outcomes, including optimizing N removal and/or preventing invasion by non-natives. By using a dynamic, process-based ecosystem simulation model, we are able to simulate various levels of hydrology and N loading that would otherwise be difficult to manipulate. We investigate the effects of hydroperiod, hydrologic residence time, N loading, and the NH4+:NO3- ratio on both N removal and the invasion success of two non-native species (Typha x glauca or Phragmites australis) in temperate freshwater coastal wetlands using Mondrian, a process-based, wetland ecosystem simulation model. We found that when residence time increased, annual N removal increased up to 10-fold while longer hydroperiods also increased N removal, but only when residence time was >10 days and N loading was >30 g N m-2 y-1. N removal efficiency also increased with increasing residence time and hydroperiod, but was less affected by N loading. However, longer hydrologic residence time increased vulnerability of wetlands to invasion by both invasive plants at low to medium N loading rates where native communities are typically more resistant to invasion. This suggests a potential tradeoff between ecosystem services related to nitrogen removal and wetland invasibility. These results help elucidate complex interactions of community composition, N loading and hydrology on N removal, helping managers to prioritize N removal when N loading is high or controlling plant invasion in more vulnerable wetlands.

Vani Region Archaeological Survey
User Collection- Creator:
- Ratte, Christopher and Mokrisova, Jana
- Description:
- The data presented here were collected in the course of an archaeological survey of the region around Vani in the Republic of Georgia, carried out between 2009 and 2011, with follow-up visits in 2014 and 2017. The survey was sponsored by the University of Michigan, the Institute for the Study of the Ancient World at New York University, and the Otar Lordkipanidze Institute of Archaeological Research in Tbilisi. , The archaeological site of Vani lies in the territory of ancient Colchis, a triangular area bordered by the Black Sea to the west and by the greater and lesser Caucasus Mountains to the north and south – famous in Greek legend as the land of the Golden Fleece and the home of Medea. Vani itself is situated approximately 70 km inland, in the foothills of the lesser Caucasus. A regional culture recognizable on the evidence of distinctive traditions of pottery and metalworking and the appearance of a network of relatively large settlements had emerged in Colchis by the late second and early first millennia BC. , Vani is one of the most extensively studied archaeological sites in Colchis. Excavations have revealed a continuous occupation sequence extending from the 8th to the 1st centuries B.C. Especially notable are the rich and unusual graves of the Classical period (6th-4th centuries), the monumental stone architecture of the Hellenistic period (3rd to 1st centuries), especially fortifications enclosing an area of approximately 6 ha, and the extensive evidence for interaction with the Mediterranean and Near Eastern worlds, including not only commercial and luxury imports (Greek transport amphorae, fine bronze and silver utensils from both the Greek world and Persia), but also local production of bronze sculpture and one long Greek bronze inscription., In spite of the richness of the site, however, important questions about its purpose and function over time remain unresolved. How extensive was the ancient settlement? Was Vani an isolated stronghold, a regional population center, a sanctuary, or a combination of two or all three? How does it compare with other sites in Colchis? In addition to ongoing research at Vani itself, regional survey provides an obvious approach to some of these questions. In previous years, examination of a number of outlying sites had already yielded remains extending in date from the Early Bronze Age to the mediaeval period., and The purpose of the regional survey project begun in 2009 was to integrate existing knowledge about Vani and environs into the kind of technological and conceptual framework characteristic of contemporary American survey archaeology. Of particular importance was the use of Geographical Information Systems (GIS) as an organizational and analytical tool, and of geophysical prospection both in the immediate environs of Vani and at regional sites. Like all regional surveys, our project recorded evidence of all periods, from prehistory to the present day, but we were particularly interested in questions having to do with the increasing social complexity of Colchis in the mid- and later 1st millennium BC – when Greek explorers began to establish colonies on the Black Sea coast of Georgia, and the Persian empire pushed up against the mountains of the Caucasus. What was the nature of Colchian society in this period? How was it affected by interaction with the larger Greek, Persian, and Pontic worlds? And how can regional survey at Vani and throughout Colchis help us to address these questions?

- Description:
- The sensitive measurement of specific protein biomarkers is important for medical diagnostics and research. However, existing methods for quantifying proteins use antibody probes that cannot distinguish between specific and nonspecific binding, limiting their sensitivity and specificity. This work establishes a method for distinguishing between specific binding to the target protein and nonspecific binding to assay surfaces using single-molecule kinetic measurements with dynamically binding probes. This is significant because it permits extremely sensitive protein measurements without requiring a high-affinity detection antibody or any washing steps, enabling streamlined and sensitive quantification of proteins even when no pair of high-quality, tightly binding antibodies is available.

- Description:
- In 2009, an American-Georgian team of four archaeologists, four archaeology students, and a geophysicist carried out a four-week season of “extensive” survey of known archaeological sites, together with geophysical prospection at selected locations. In a second four-week season in 2010, with the additions of a geologist and an archaeobotanist, we continued our program of documentation of known sites and of exploratory geophysical prospection, and we also carried out limited test excavations at a number of sites. We returned for a shorter (one- to two-week) study seasons in 2011 and 2014, focusing on museum and archival research in Vani, Kutaisi, and Tbilisi., The area covered by our survey extends 15 km both east and west of Vani, and as far as 10 km south of Vani, from the Phasis River plain at approximately 50 m above sea level to the lower slopes of the lesser Caucasus, at approximately 1000 m above sea level. The purpose of the program was to visit all the previously identified archaeological sites in the region, and to integrate existing knowledge into a database of sites and a Geographical Information System. Each entry into this database is recorded as a dataset in this deposit. Entries recorded in 2009 are prefaced with the letter “A,” those recorded in 2010 are prefaced with the letter “B.” A single entry added in 2011 received the preface, “C.” In carrying out the survey, we depended heavily on the unpublished dissertation by Sulkhan Kharabadze, “Vanis Qveq’nis” Arqeologiuri Ruk’a (dzv.ts. VIII – akh.ts. III ss.) – Archaeological Map of the Territory of Vani (8th Century BC – 3rd Century AD) (Ph.D. dissertation: Georgian Technical University 2008). A map showing the locations of all the sites recorded by the survey is attached to this dataset., Our procedure for each site visit was as follows: we drove to the nearest village and searched out a local guide who could take us to the place we wished to see. We drove as far as we could to each site, then got out and walked, using GPS-equipped field computers (Trimble Geo-XM) to make a continuous record of our path. We recorded the lay of the land and any artifacts we saw en route (pottery sherds, traces of burnt daub, lithics and stone objects, architectural features in situ). We designated as points of interest any significant archaeological remains (concentrations of pottery, in situ features, notable stray finds, etc.), and every place we could identify where earlier discoveries had been made or archaeological excavations carried out. For every point of interest, we recorded the latitude, longitude, and elevation; took a series of digital photographs; and made a grab bag collection of pottery and other finds if possible. Where appropriate, we took basic measurements of architectural features (e.g., of Mediaeval towers). We also kept records of local place names, the names of our local guides, and any miscellaneous information they gave us. , Certain sites were selected for further investigation. These included Saqanchia A001, where we carried our geophysical survey and limited excavation; Shuamta, Melashvilebisgora A033, where we also carried out geophysical survey and limited excavation; Kveda Bzvani A047, where we carried out controlled collection of surface finds; and Zeda Bzvani, Meskhebisgora, A053, where we also carried out controlled collection of surface finds., The datasets recorded in this deposit include basic descriptions of each site, citations to previous publications, and links to relevant maps, photographs, and drawings. Where they exist, maps for individual datasets are labeled according to the name and number of the site, e.g., DapnariA002Map.jpg. The labels for photographs taken during the field season record their numbers in the sequence of photographs taken that season, e.g., Vani09.0047.jpg. A complete list of all photographs recorded in this way is available for download. Photographs and drawings of artifacts from individual sites made after the season are labeled with the names of the sites followed by the numbers assigned to the objects, with photographs saved as jpeg files, and drawings saved as tiff files; thus KvedaBzvani11-14.jpg is a photograph of objects 11-14 from the site of KvedaBzvani, while KvedaBzvani11-14.tif is a set of drawings of the same objects. Finally, drawings of sites where excavations were carried out are labeled with the name of the site, the number of the trench (if applicable), and the type of drawing, so that Shuamta2010.1Plan is a plan of Trench 2010.1 at Shuamta., and In addition, the collections in this deposit group datasets together according to important characteristics such as period (Bronze Age, Iron Age, etc.) or type (settlement, fortification, burial, and so on).

Specifically, the goal is to capture the observation of the smoothing of the peaks in dV/dQ and retention of the peaks in d^2 (backslash)delta/dQ^2 at higher C-rates. The retention of the peaks at higher charging rates enables better estimation of the cell capacity. To achieve this goal a reduced order electrochemical and mechanical model with multiple particles with a size distribution is developed. This allows us to capture the smoothing and preservation of the phase transitions in the voltage and expansion measurements at high C-rates, respectively. The model is written in Matlab software.
