On Friday, September, 21, 2018, I attended the New York Mets versus the Washington Nationals baseball game at Nationals Park in Washington, D. C. Jacob deGrom started for the Mets while Joe Ross started for the Nationals. Jacob deGrom pitched well over seven innings with one run on three hits with eight strikeouts. The Mets beat the Nationals with a score of 4 to 2. Below are some pictures I took during the game.
On September 7, 2018, I walked around the National Mall in Washington D.C. and went inside some of the museums at the Smithsonian Institution including the National Air and Space Museum, National Museum of American History, Hirshhorn Museum and Sculpture Garden, and National Museum of Natural History. Below are some pictures taken in Washington D.C. while outside and inside the museums.

On Friday, September, 7, 2018, I had tickets for the baseball game of the Chicago Cubs versus the Washington Nationals at Nationals Park in Washington, D. C. Unfortunately due to weather including rain and thunderstorms, the game was never completed and made official. Only a bit over 1 inning was played. Jon Lester started for the Cubs while Joe Ross started for the Nationals. No runs were scored. The game was later postponed for makeup the following Saturday as a single admission doubleheader. Below are some pictures I took at the game along with the official details regarding makeup from the Washington Nationals Twitter.
I had an opportunity to attend the American Telemedicine Association 2018 Conference (ATA18), in Chicago, Illinois, at McCormick Place. The annual gathering brings together healthcare professionals, business professionals, and leaders in different areas of healthcare and technology and occurred from Sunday April 29 to Tuesday May 1, 2018. ATA18 was billed as the world’s largest telehealth networking event with a focus on the latest innovations. The term telehealth includes many technologies and ways to deliver virtual medical, health, and education services. More than 150 different exhibitors were in attendance. Attendees also had the opportunity to attend over 100 sessions.
I attended sessions including “Technology in Service to Patients and Consumers: Emerging Trends in Virtual Care,” “What Does Artificial Intelligence Have to Do with Population Health?,” and “New Models for Telehealth at Scale: Strategic Telehealth Expansion Initiatives at DoD and VA.” A doctor from Partners Healthcare in Boston discussed four different ways that they are using artificial intelligence to help in the hospital setting. For example, there was some discussion of how a good predictor for when a patient may be re-admitted is if they live alone and have no support systems. It was also interesting to see all the ways the army, navy, airforce, and department of veterans affairs of the U.S. has expanded ways to treat patients without the physician actually seeing them in an office. In particular, the navy discussed how with radiology most of their radiologists are now located in several larger cities in the U.S. and that at some of their sites there is no radiologist. Instead, around 25% to 30% of all the work the radiologists do is for other sites outside of their location. It also seemed that the largest current component for physician patient interactions is using telehealth to deliver behavioral medicine like cognitive behavioral therapy.
Below are some of the pictures I took while at the ATA annual conference in 2018, in Chicago, IL.
I am pleased that a paper titled “A Time-Domain Measurement System for UWB Microwave Imaging” has been published in IEEE Transactions on Microwave Theory and Techniques, in 2018, that I am a co-author on through work with the Celadon Research Division of Ellumen Inc. This paper discusses a fully automatic time domain measurement system for microwave imaging using a pair of movable antennas to transmit and receive custom UWB pulse designs. The system described in the paper incorporates some elements from the Microwave Imaging Device patent previously discussed where a pair of movable antennas are independently controlled to rotate around a region of interest. This paper builds upon work previously presented in 2017, in IEEE Transactions on Microwave Theory and Techniques in the paper “A Phase Confocal Method for Near-Field Microwave Imaging” and at the IEEE AP-S Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting in the the poster presentation titled “Experimental Microwave Near-field Detection with Moveable Antennas.” The prior two works discussed using the system in the frequency domain with a vector network analyzer to generate and receive signals. In this new paper the time domain use of the system is described using an arbitrary waveform generator to generate signals and a digital phosphor oscilloscope to receive signals.
I have included an excerpt from the accepted version of the paper below. DOI: https://doi.org/10.1109/TMTT.2018.2801862 © 2018 IEEE. Personal use of this material is permitted.

Figure 2 in the paper shows the system as was set up at Ellumen Inc. along with a PVC cylinder placed in the middle tray. A reconstructed image from data collected using the setup in Figure 2 using the delay multiply and sum (DMAS) imaging algorithm is shown in Figure 9. In Figure 10(a) the object was changed to a metallic object and a long wood square object both placed in the middle tray. A reconstructed image produced using DMAS is shown in Figure 10(b). Also note that the DMAS algorithm was programmed on eight nVidia Tesla GPUs which allowed images to be produced in under 1 minute. A comparison between the time domain system and frequency domain system was performed in the paper but is not included in the above excerpt. This analysis showed that both methods of data collection can allow for accurate reconstructed images to be obtained. The software to control the data collection was also updated as presented in this paper so that it takes 20 minutes to complete both incident and total field data collections. I encourage you to download and read the full “A Time-Domain Measurement System for UWB Microwave Imaging” paper from IEEE for full details and analysis.
