The [Simplicity Living Study Circle of Northern Virginia](https://www.coachingwithdanijk.com/study-circle) meets on the first Saturday of each month from 4:00 to 5:30 PM at Lacey Woods Park in Arlington, Virginia. **This is rain or shine outdoor event.** This free community group offers a unique and empowering space for individuals seeking to live a simpler, more intentional life. Led by participant-driven discussions, our circle is designed to foster connection and support as members share their experiences, wisdom, and insights on simplifying their lives. Hosted by members of the Simplicity Living Circle of Northern Virginia, we aim to bring together like-minded people who are passionate about mindful living and environmental care. Whether you're new to the journey of simplicity or looking to deepen your practice, we invite you to join us in this nurturing and inclusive environment.

Please join the [Veg Society of DC](vsdc.org) Animal Rights Discussion and Education Group for another great discussion. The next event will be the third and final event in our series on Theories of Change in the Animal Rights movement. We will apply theory to practice and discuss the campaign to prohibit the sale of foie gras in DC through a ballot initiative. We are excited to welcome a speaker who is on the forefront of this effort and to hear from them firsthand how this initiative fits into their organization’s theory of change! Afterwards, we hope you’ll join us for dinner at DC Vegan. **What is the Animal Rights Discussion and Education Group?* If you’ve been looking for a way to educate yourself on animal rights and issues affecting animals in our world today with the support of a like-minded community, then this group is for you. The VSDC Animal Rights Discussion and Education Group will discuss thoughts, questions, concerns, and news related to animal rights. It seeks to provide a safe space for discussions around issues affecting captive animals, farmed animals, animals used in research, wild animals, companion animals, and more. All are welcome, from those well-versed in animal rights philosophy and issues to those who are just starting off on their journey and are curious to learn more. Please come with an open mind, an open heart, and a willingness to engage with diverse opinions with curiosity and respect. The plan is for the group to meet every month, alternating between Zoom and in person. The topic of each meeting and any accompanying materials will be planned in advance and posted in event announcements via this VSDC meetup group. Participants are encouraged to offer topic ideas and materials for discussion at subsequent meetings. **Date / Time:** Saturday, February 7th, at 4:15 pm. **Location:** Pea Street Yoga Studio (right above DC Vegan, where we will eat dinner afterwards!) *Email 'ARdiscuss@vsdc.org' for further information.* **VSDC: More Than A Meetup** We are delighted to have you as part of The Veg Society of DC Vegan Meetup group, and we look forward to seeing you at our events.

Date : Feb 7 2026 13:00 - 15:00 EST Title: Symmetry, Topology, and Magnetoelectric Multiferroicity — Ferroelectric 'Tweezers' for Quantum Magnetism in Hexagonal Ferrites Abstract: The scalability of future quantum and spintronic hardware is currently facing a "physical wall": the challenges of excessive heat dissipation and environmental magnetic noise. To overcome these barriers, materials where magnetism can be controlled with high precision and minimal energy will be highly desirable. Magnetoelectric multiferroic hexagonal rare-earth ferrites (h-RFeO3, R: rare earth) have emerged as an important platform for this mission, offering a unique "playground" where symmetry and topology dictate functionality. In this talk, I will provide a comprehensive overview of research progress on these materials over the last decade. We will explore how a specific structural transition—trimerization—breaks symmetry to create a robust state known as improper ferroelectricity as well as weak ferromagnetism. The coupling between the ferroelectric and magnetic orders leads to a "ferroelectric tweezer" effect, where the material's ferroelectric domain spatially anchors and manipulates magnetic domains. Furthermore, we will address the "readout challenge": how to detect the diminutive magnetic moments inherent in these systems. I will show how the non-coplanar spin topology acts as a signal amplifier, enabling high-fidelity readout of magnetic states through spin-transport. By understanding the "solid science" of these complex oxides, we can define the roadmap for a new generation of stable, low-power topological electronics. Biography: Xiaoshan Xu is Susan J.

Is it possible to grow spiritually in isolation? It’s quite natural to think about our personal spiritual growth and development in terms of improving our own life, but how does that relate to the real world around us? What if our own personal growth is closely connected to the growth and progress of others? And what if turning our gaze beyond just ourselves to also focus on the progress of others and of our communities not only helps make the world a better place but is actually what helps us grow? Come join a different kind of conversation – one that welcomes every perspective in a search for the underlying truths that unite us all – as we discuss the spiritual perspectives offered by the Bahá’í Teachings on how practicing selflessness and incorporating service to others can actually further our own growth. Join us for a lively discussion as we explore the ways in which self-development is connected with that of those around us. *"Whosoever has lost himself has found the universe and the inhabitants thereof. Whosoever is occupied with himself is wandering in the desert of heedlessness and regret. The "master-key" to self-mastery is self-forgetting."* – Bahá'í Teachings \*\*\* This event is free and open to all regardless of background or belief. Donations will not be accepted.

Title: Biology-Inspired Neural Networks with Multi-Directional Propagation of Values and Distributions Date: Feb 8 2026 10:00 am - Noon EST Summary: While biological axons can propagate in both directions, current ANNs are focused on unidirectional propagation. Also usually they only propagate values, while uncertainty is shown also crucial for making decisions of biological organisms - suggesting to propagate also variance, probability distributions. I will talk about novel KAN-like approach to ANNs repairing these lack by using neurons containing inexpensive local joint distribution model as polynomial, allowing to freely change propagation direction by just switching indexes, also propagate entire probability distributions represented by vectors of moments. Beside backpropagation, it also allows many additional training approaches, like direct estimation, tensor decomposition, and through information bottleneck. Speaker: Dr Jarek Duda is an assistant professor at Jagiellonian University. He holds degrees in computer science (PhD), mathematics (MSc) and physics (PhD). He is mainly focused on physics foundations, information theory, statistical analysis, and is known for introduction of asymmetric numeral systems. Moderators: Dr. Pawel Gora, CEO of Quantum AI Foundation and Dr. Sebastian Zajac , member of QPoland Zoom registration form will be provided no later than 1 hour prior to the event's start time.

***Arcs*** is a sharp, tactical space opera game, for 2–4 players, set in a dark yet silly universe. Players represent officials from a distant, decaying and neglectful Empire who are now free to vie for dominance whether through battle, gathering scarce resources or diplomatic intrigue. Ready yourself for dramatic twists and turns as you launch into this galactic struggle. A deck of cards in 4 suits with ranks from 1-7 (2-6 for fewer than 4 players) defines the action selection system. These cards are played in a trick-taking adjacent system to select actions, take the initiative and declare Ambitions. The 3 declared Ambitions are what will score in that deal. Timing is everything. Bad hands must be mitigated by careful card play and benefitting from other players' card play. Battles are resolved quickly with the attacker choosing their level of risk. The defenders must be prepared with adequate defensive ships and cards in their tableau.
