- Description:
- Interest in quantitative imaging of Y-90 is growing because transarterial radioembolization (RE) with Y-90 loaded microspheres is a promising and minimally invasive treatment that is FDA approved for unresectable primary and metastatic liver tumors. These cancers are a leading cause of cancer mortality and morbidity. Radioembolization is a therapy that irradiates liver tumors with radioactive microspheres administered through a microcatheter placed in the hepatic arterial vasculature. Radioembolization is based on the principle that healthy liver and tumor are mainly vascularized by the portal vein and the hepatic artery respectively. As a result, radioactive microspheres are preferentially located in the lesions after they are administered via the hepatic artery.

- Description:
- In order to better understand the large-scale impacts of smaller-scale gravity waves in the upper atmosphere of Mars, a modern whole atmosphere, nonlinear, non-orographic, spectral gravity wave parameterization scheme (Yigit et al., 2008) has been added to the ground-to-exosphere 3-D general circulation model, M-GITM (Bougher et al., 2015), which previously did not account for the effects of this physical process. New atmospheric simulations have been run for cases which did and did not utilize this gravity wave parameterization as well as for cases designed to test the sensitivity of certain adjustable parameters within the scheme. After including the gravity wave parameterization scheme into M-GITM, large impacts are found on the simulated mean thermospheric horizontal velocities and temperature structure, especially within the altitude range of 90-170 km (Roeten et al., 2022). The most notable of these impacts include a reduction in speed of the thermospheric easterlies in the summer hemisphere as well as overall cooling, on average, at altitudes above 120 km., Simulations were run for two different seasons at Mars, a solstice (Ls=270) and an equinox (Ls=180). The output from these simulations have been averaged over all local times over a 15-day time period, starting on the day of the solstice or equinox. The output has also been zonally averaged over all longitudes. Files containing these zonally and temporally averaged files are named starting with “MGITM_ZonalAvg”. Both solstice and equinox cases have been simulated once without including the gravity wave parameterization (“nogw”) and once with the gravity wave parameterization included (“withgw”). Additional simulations of the Ls=270 solstice have been done individually adjusting the horizontal wavelength and maximum source flux parameters within the gravity wave scheme. , and Other M-GITM simulations have also been provided in a different format. These M-GITM simulations are ‘flythroughs’ of model output, extracted along the same trajectory path of the MAVEN spacecraft, which allows for better data-model comparisons with in-situ MAVEN/NGIMS (Neutral Gas and Ion Mass Spectrometer) observations. These simulations have been done for three different NGIMS observational campaigns, both for cases that include and do not include the effects of gravity waves. Output from these simulations has NOT been averaged; instead, output from each simulated MAVEN orbit is included within the file. These files are named starting with “MGITM_TempExtraction” or “MGITM_WindExtraction” based on whether the MGITM flythrough was designed to be compared to MAVEN/NGIMS temperature or wind profiles, respectively.

1243. Video data of predation and parasitism by arthropods on small vertebrates in lowland Peruvian Amazon
- Creator:
- Grundler, Michael C, Grundler, Maggie G, and Herrera, V.
- Description:
- Nighttime and diurnal surveys in the lowland Peruvian Amazon of Los Amigos Biological Station were conducted in order to describe herpetological diversity at this site. As a result of these surveys, the predation event between a Pamphobeteus sp. and Marmosops sp. and the myiasis of Ranitomeye uakarii were observed. The video footage was recorded in order to document these interesting interactions between arthropod predators and parasites and vertebrate prey and hosts, and are included for publication in the short communication "Ecological interactions between arthropods and small vertebrates in a lowland Amazon rainforest" in the journal Amphibian and Reptile Conservation.

- Description:
- We perform a geomagnetic event simulation using a newly developed magnetohydrodynamic with adaptively embedded particle-in-cell (MHD-AEPIC) model. We have developed effective criteria to identify reconnection sites in the magnetotail and cover them with the PIC model. The MHD-AEPIC simulation results are compared with Hall MHD and ideal MHD simulations to study the impacts of kinetic reconnection at multiple physical scales. At the global scale, the three models produce very similar SYM-H and SuperMag Electrojet (SME) indexes, which indicates that the global magnetic field configurations from the three models are very close to each other. At the mesoscale we compare the simulations with in situ Geotail observations in the tail. All three models produce reasonable agreement with the Geotail observations. The MHD-AEPIC and Hall MHD models produce tailward and earthward propagating fluxropes, while the ideal MHD simulation does not generate flux ropes in the near-earth current sheet. At the kinetic scales, the MHD-AEPIC simulation can produce a crescent shape distribution of the electron velocity space at the electron diffusion region which agrees very well with MMS observations near a tail reconnection site. These electron scale kinetic features are not available in either the Hall MHD or ideal MHD models. Overall, the MHD-AEPIC model compares well with observations at all scales, it works robustly, and the computational cost is acceptable due to the adaptive adjustment of the PIC domain.

- Description:
- Three sensitivity analyses were performed. First, a second matching step was performed in which two controls were selected for each case, where possible using a nearest neighbor and caliper metric. Controls needed to have propensity scores within 0.1 of the case to be selected. Thirty-eight of the 39 cases had at least one control using this method and for 36 cases two controls could be selected. The average difference between case and control propensity adjuvant RT was 0.008 (range 0.00003-0.095). A second sensitivity analysis was performed to guard against immortal time bias. In order to mitigate the possibility of this effect, cases known not to have undergone adjuvant RT have been screened for suitable follow-up without a recurrence (local or regional recurrence, metastatic failure, and/or death) to ensure that if adjuvant RT had been prescribed as part of the multi-modality treatment regimen, that it would have been initiated. Three months was selected as the mandatory follow-up time. One to one matching was carried out and all 39 cases were matched to a control. A third sensitivity analysis was performed to account for stage migration seen in control patients that presented to the University of Michigan with more advanced disease. Patients that underwent adjuvant radiation were matched one to one with control group patients who did not receive adjuvant radiation, and who had the same stage at diagnosis as compared to stage at University of Michigan presentation.
