Michael Cheeseman - Because Of You



The environments definitely effect your body, but the cameras are even more susceptible to the elements. This past winter, all the cameras were freezing because it was negative thirty-five to negative forty every single day.




Michael Cheeseman - Because of You



What is the most important leadership lesson you have learned, and how is it valuable to you today? That you learn more from losing than you do from winning, and knowing how to lose is important. In Major League Baseball, a career batting average of .300 gets you into the Hall of Fame. With this average, you lose 7 out of 10 times, which would break most people. I take this approach in sales because whenever I lose, it fuels me to do better.


The study used existing datasets* of student populations across the continental U.S. and satellite-derived concentrations of the pollutants from 2017 through 2019, with pollutant estimations verified by established EPA monitoring networks. One of the pollutant models explicitly accounts for nitrogen dioxide derived from traffic, which is especially relevant for low-income schools because they tend to be located near busy roadways. The pollutants reflect ambient air pollution, not air pollution inside school buildings.


As you can probably guess, the answer is a resounding yes! One useful aspect of machine learning like our Random Forest is that it can recognize patterns in the data that might be hard to pick out with the human eye. Thus, it might tell me things about my taste in chocolate that I never would have known otherwise. For example, I generally do not like cashews in my chocolate but after analyzing the results from the model I might realize that I do like some bars with cashews in them as long as they are paired with fruits or spices. This interpretability is one reason why many researchers in earth science are turning to machine learning methods like Random Forest models: because they can tell us about connections in our world we might not have known otherwise!


Auditory bulla cavitation defects are a cause of otitis media, but the normal cellular pattern of bulla mesenchyme regression and its failure are not well understood. In mice, neural-crest-derived mesenchyme occupies the bulla from embryonic day 17.5 (E17.5) to postnatal day 11 (P11) and then regresses to form the adult air-filled bulla cavity. We report that bulla mesenchyme is bordered by a single layer of non-ciliated epithelium characterized by interdigitating cells with desmosome cell junctions and a basal lamina, and by Bpifa1 gene expression and laminin staining of the basal lamina. At P11-P12, the mesenchyme shrinks: mesenchyme-associated epithelium shortens, and mesenchymal cells and extracellular matrix collagen fibrils condense, culminating in the formation of cochlea promontory mucosa bordered by compact non-ciliated epithelial cells. FBXO11 is a candidate disease gene in human chronic otitis media with effusion and we report that a bulla cavitation defect initiates the pathogenesis of otitis media in the established mouse model Jeff (Fbxo11Jf/+). Persistent mesenchyme in Fbxo11Jf/+ bullae has limited mesenchymal cell condensation, fibrosis and hyperplasia of the mesenchyme-associated epithelium. Subsequent modification forms fibrous adhesions that link the mucosa and the tympanic membrane, and this is accompanied by dystrophic mineralization and accumulation of serous effusion in the bulla cavity. Mouse models of bulla cavitation defects are important because their study in humans is limited to post-mortem samples. This work indicates new diagnostic criteria for this otitis media aetiology in humans, and the prospects of studying the molecular mechanisms of murine bulla cavitation in organ culture.


Nominations for the Culture Award, part of Celebrate! Colorado State, started pouring in, with peers recognizing numerous individuals and units for going above and beyond to effect culture change at CSU. That made for a very difficult deliberation for council members, but PCC Chair and Vice Provost for Faculty Affairs Sue James said it was a good position to be in because it revealed just how much work is being done across CSU.


Chudler, a Ph.D. candidate with Professor Steven Rutledge, was drawn to the policy colloquium because he always has enjoyed leading science outreach. He looks forward to learning how effective communication of science can be used to shape government guidelines.


Schulte applied for the grant because he needed funding to pursue a research project idea for his Ph.D. prospectus. The grant will pay for the majority of his tuition, research and travel costs for the rest of his degree program.


Based in Boise, Idaho, the flight crew flew 16 six-hour missions to collect smoke samples and data. Boise was chosen because almost every August there is a wildfire burning within a two-hour flight of the city. The WE-CAN team included around 100 scientists and engineers, with many of them stationed on the ground, monitoring fires, smoke and weather to guide the plane.


Kodros is one of a handful of students who have received both the Riehl and Alumni awards. When Kodros was recognized with the Riehl Award in 2016, however, he was not able to accept it in person because he was delayed in India on visa complications following a research trip there.


Hands-on data collection was necessary to advance our understanding of cloud formation over the Southern Ocean because our current assessment is based almost entirely on satellite observations. This gap in knowledge leads to inaccurate climate models.


With the support of the ASCENT award as well as an additional EUROCHAMP-2020 research grant, I spent this summer at the Institut de Combustion Aérothermique Réactivité et Environment (ICARE), a CNRS laboratory, in Orleans, France investigating the quantum yields of the carbonyl species, Methyl Ethyl Ketone (MEK). Like acetone, MEK is important in atmospheric chemistry because it has a sufficiently long lifetime (5 days in the case of MEK) to be lofted into the upper troposphere. There, these ketones can be photolyzed, and lead to odd hydrogen (HOx = HO2 + OH) radical production. Thus, the photolysis of these compounds impacts the concentrations and lifetimes of greenhouse gases and other atmospheric pollutants. However, the rates of ketone photolysis are uncertain. In order to quantify them, I used ASCENT fellowship funding to support a two-month period of study during June and July of 2017 using a unique facility located in Orleans, France. During this time, I helped perform outdoor chamber experiments using natural sunlight to measure rates of MEK photolysis as well as bench-top experiments to measure UV absorption cross-sections of MEK at atmospherically relevant wavelengths and temperatures. This data will help improve the modeling of these compounds, and therefore our understanding of the upper troposphere radical budget, upper troposphere ozone production, and lifetimes of pollutant and greenhouse gases.


One leaves [a presentation given by Sue] feeling like an expert in the area, because Sue has so effectively described the science question, her approach, and findings, deconstructing even the most complex microphysical processes, and explaining the new insights gained from her work. 041b061a72
