**The rules are simple:** Take photographs **Each and Every Day** and post your best **ONE** (1) shot of the day - **EACH DAY** for **March**. If you happen to miss a day or two (life happens), it is **OK** to catch up and upload the photos for the days missed or just skip those days. **Please don't post over 2 to 3 at a time**. This is part of the learning process. **DO NOT POST TO THE ALBUM *UNTIL* AFTER 03/01/2026**. Please use a browser like Chrome and the Meetup.com website to post the images, as **the Meetup app does not handle albums very well**. Towards the top-left of the page is a link to **Add Photos** for uploading your photo to the album. **CONFIRM** **that your photo was Added to the correct Album.** Remember to post your **best photo (JUST ONE)** you took every day on that day! **DO NOT POST PHOTOS FROM ANY OTHER TIME!** If you have time to post an older image, you can take a new image and post it. Be creative. Please **add a caption** to know how far you are in the process. After you upload the image you took that day, find your photo at the end of the album, and edit the caption to state the day and total of days in the month like this:?/31. You can add the title of the image if you wish. A good title can make a photo! So, your photo for the **March 1st** caption would be "**1/31: My great photo!**" \*\* Adding a caption helps you keep track of where you are in the month. It does help. The purpose is to have fun and get in the habit of shooting every day. Learn to use your camera. Read your manual and test out a new feature you have never used before. Sometimes picking a theme/project can help focus (pun intended), like flowers, your pet(s), a lens you haven't used in a while, or whatever your passion is. Or try something new... The **end date is 03/31/2026**. Meetup.com does not allow events to be longer than 2 weeks. Other images that were not taken by you will be removed. Please keep the images family-friendly. You need to be a member of the Virginia Beltway Photography Group. I look forward to seeing how far people go and grow as better photographers!

Title : Design of a Quantum Photonic Full Adder Gate based on an 8-mode Integrated Optical Circuit Date: Feb 28 2026 Noon - 14:00 EST Abstract: Multiport interferometers designed using the Clements decomposition algorithm can be used to implement compact quantum-photonic full-adder (FA) gates on photonic integrated circuits (PICs). By expressing each element of the FA gate matrix in terms of the permanent of a non-unitary matrix, enabled through Boson sampling, the required number of MZIs in the gate can be further reduced. In this presentation, we will discuss the design of an FA gate modeled as a four-photon scattering process on an eight-mode integrated optical circuit, where the permanents of submatrices determine the output probabilities. Simulation results demonstrate a fidelity of 1 and a success probability of 2.22 × 10⁻⁴ for the FA gate. We will also examine the impact of phase-shifter and attenuator variations on fidelity and success probability using Ansys Q-Interconnect software. Finally, we will compare the performance of the proposed FA gate with a benchmark Toffoli gate designed using the same approach. Speaker: Shafiqul Hai received the B.Sc. degree in Electrical and Electronic Engineering from the Bangladesh University of Engineering and Technology (BUET), Dhaka, Bangladesh, in 2007, and the M.Eng. (Thesis) and Ph.D. degrees in Electrical Engineering from McGill University, Montreal, QC, Canada, in 2011 and 2016, respectively. He is currently an Assistant Professor in the Department of Electrical and Computer Engineering at Lakehead University. His research interests include the modeling and characterization of compact nanophotonic devices and components for next-generation optical fiber and RF communication systems, as well as quantum computing on photonic integrated circuits. He is the author or coauthor of more than 12 peer-reviewed journal papers and 15 conference publications. Moderators: Dr. Pawel Gora, CEO of Quantum AI Foundation ([https://www.qaif.org/](https://www.qaif.org/)) , Dr. Sebastian Zajac , member of QPoland ([https://qworld.net/qpoland/](https://qworld.net/qpoland/)) This is an online event. Zoom registration form will be emailed to registrant and posted on the event forum by Feb 28 2026 11:00 am EST.

Hey Poetry Lovers! This group is on a roll. Here’s the gist: We meet at the **Capital One Café in Chinatown** from **12pm - 2pm** every other week. For enrichment, we start by reading and reflecting on a **“published poem”**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems we’ve read [here](https://docs.google.com/spreadsheets/d/e/2PACX-1vSyE_wCLQCPHRrKmN5F9tOIeeRQUZESxjRXGVBoCF2uU8Gm0_d0uECiCBCQXEy6ksxfsBOhtRIOpW3T/pubhtml?gid=0&single=true&widget=true&headers=false%22%3E%3C/iframe%3E). Or submit suggestions for future meetings [here](https://docs.google.com/forms/d/e/1FAIpQLSexGc2Z2Kp6bZW0D3_hfJ7NUUkfNHf7TXX-43FglCeBd9EF2Q/viewform?usp=send_form). Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; you’re welcome to come even if you prefer just to listen.) We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you haven’t used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the “DC Poetry Workshop”, and can help you navigate the app if you have questions. Finally, if you plan on sharing a poem, consider how you will do so. Some options include: * Print 5-10 copies to distribute in person * Take and share screenshots in the Discord chat. * Copy the poem into a google doc, change sharing settings to “anyone with link”, and copy the google doc link into the Discord chat. Most importantly, we’re excited to meet you! Catch you on Saturday, Diego / Ian / Cayden / Nate / Otasha / Lia / An

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association: They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved. Going forward our meetings will be hybrid.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
