Together We Flourish, Remotely

Like many other companies, Viget is working through the new challenge of suddenly being a fully-distributed company. We don’t know how long it will last or every challenge that will arise because of these unfortunate circumstances, but we know the health and well-being of our people is paramount. As Employee Engagement Manager, I feel inspired by these new challenges, eager to step up, and committed to seeing what good can come of this.

Now more than ever, we want to maintain the culture that has sustained us over the last 20 years – a culture that I think is best captured by our mantra, “do great work and be a great teammate.” As everyone is adjusting to new work environments, schedules, and distractions, I am adjusting my approach to employee engagement, and the People Team is looking for new ways to nurture and protect the culture we treasure.

The backbone of being a great teammate is knowing each other and caring about each other. For years the People Team has focused on making sure people who work at Viget are known, accepted, and cared about. From onboarding to events to weekly and monthly touchpoints, we invest in coworkers knowing each other. On top of that, we have well-appointed offices where people like to be, and friendships unfold over time. Abruptly becoming fully distributed makes it impossible for some of these connections to happen organically, like they would have around the coffee machine and the lunch tables. These microinteractions between colleagues in the same office, the hellos when you get off the elevator or the “what’d you get up to this weekend” chit chat near the seltzer refrigerator, all add up. We realize more than ever how valuable those moments are, and I know I will feel extra grateful for them when we are all back together.

Until that time, we are working to make sure everyone at Viget feels connected, safe, healthy, and most importantly, together, even when we are physically apart. We are keeping up our weekly staff meetings and monthly team lunches, and we just onboarded a new hire last week as thoroughly as ever. There are some other, new ways we’re sparking connections, too.

New ways we're sparking connections:

Connecting IntentionallyWe are making the most of the tools that we’ve been using for years. New Slack channels have spun up, including #exercise, where folks are sharing how they are making do without a gym, and #igotyou, a place where folks can post where they’ve found supplies in stock as grocery stores are being emptied at an alarming pace.
Remote Lunch TablesWe have teammates in three different time zones, on different project teams, and at different stages of life. We’ve created two virtual lunch tables, one at 12PM EST and one at 12PM MST, where folks can join with or without their lunches and with or without their kids, partners, or pets. There are no rules or structure, just an opportunity to chat and see a friendly face as a touchpoint to your day.
Last Weekend This MorningCatching up Monday morning is a great way to kick off your week. Historically, I’ve done this from my desk over coffee as I greet folks coming off the elevator (I usually have the privilege of sitting at our front desk). I now do this from my desk, at home, over coffee as folks pop in or out of our Zoom call. One upshot of the new normal is I can “greet” anyone who shows up, not just people who work from my same office. Again, no structure, just a way to start our week, together.
Munch MadnessYes, you read that right. Most of the sports world is enjoying an intermission. Since our CEO can’t cheer on his beloved Cavaliers and our VP of Design can’t cheer on his Gators, we’ve created something potentially much better. A definitive snack bracket. There is a minimal time commitment and folks with no sports knowledge can participate. The rules are simple: create and submit your bracket, ranking who you believe will win each snack faceoff. Then as we move through the rounds, vote on your favorite snacks. The competition has already sparked tons of conversation and plenty of snack hot takes. Want to start a munch-off of your own? Check out our bracket as a starting point.
Virtual Happy HoursSigning off for the day and shutting down your machine is incredibly important for maintaining a work-life balance. Casually checking in, unwinding, and being able to chat about your day is also important. We have big, beautiful kitchens in each of our offices, along with casual spaces where at the end of any given day you can find a few Vigets catching up before heading home. This is something we don’t want to miss! So we’re setting up weekly happy hours where folks can hop in and say hi to each other face-to-face. We’ve found Zoom to be a great platform so we can see the maximum number of our teammates possible. Like all of our other events, it’s optional. There is also an understanding that your roommate, kid, significant other, or pet might show up on screen (and are welcome!). No one is shamed for multitasking and we encourage our teammates to join as they can. So far we’ve toasted new teammates, played a song or two, and up next we’ll play trivia.

At the end of the day, we are all here for one reason: to do great work. Our award-winning work is made possible by the trust we’ve built within our teams. Staying focused and accountable to ourselves and our clients is what drives our motivation to continue to show up and do our best. In our new working environment, it is crucial that we can both stay connected and productive; a lot of teammates are stepping up to support one another. Here are a few ways we are continuing to foster our “do great work” mantra.

New ways we're fostering great work:

Staying in TouchThe People Team is actively touching base with every employee. Our focus is on their health, productivity, and connection. These 1:1s have given us a baseline for how we can provide the best support for our team, from making sure they're aware of flexible work options to setting them up with the tools they need to be successful. We’ve delivered chairs, monitors, and helped troubleshoot in-home wifi issues. We are committed to making sure every Viget is set up for success.
Sharing is CaringWe’re no stranger to remote teams. We have four offices across the U.S. and a handful of full-time remote folks, and we’ve leaned on our inside experts to share their expertise on remote work. Most recently, ourData & Analytics Director, who has been working remotely full time for five years, gave a presentation on best practices for working from home. His top tips for working from home include:
  • Minimize other windows in remote meetings.
  • Set a schedule and avoid midday chores.
  • Take breaks away from the screen.
  • Plan your workday on your shared calendar.
  • Be mindful of Slack and social media as a distraction.
  • Use timers.
  • Keep your work area separate from where you relax.
  • Pretend that you’re still working from work.
  • Experiment and figure out what works for you.

Our UX Research Director also stepped up to share her expertise to aid in adjusting to our new working conditions. She led a microclass on remote facilitation where she shared best practices and went over tools that support remote collaboration. Some of the tools she highlighted included Miro, Mural, Whimsical, and Jamboard. During the microclass she demonstrated use of Whimsical’s voting feature, which makes it easy for distributed groups to establish discussion topic priorities.

Always PreparedHaving all of our project materials stored in the Cloud in a consistent, predictable way is a cornerstone of our business continuity plan. It is more important than ever for our team to follow the established best practices and ensure that project files are accessible to the full Viget team in the event of unplanned time off. Our VP of Client Services is leading efforts to ensure everyone is aware of and following our established guidelines with tools like Drive, Slack, Github, and Figma. Our priorities are that clients’ needs are met, quality is high, and timelines are honored.

As the pandemic unfolds, our approach to employee engagement will evolve. We have more things in the works to build and maintain connections while distributed, including trivia and game nights, book clubs, virtual movie nights, and community service opportunities, just to name a few. No matter what we’re doing or what tool we’re using to connect, we’ll be in it together: doing great work, being great teammates, and looking forward.

A Marstrand type slicing theorem for subsets of $mathbb{Z}^2 subset mathbb{R}^2$ with the mass dimension. (arXiv:2005.02813v2 [math.CO] UPDATED)

We prove a Marstrand type slicing theorem for the subsets of the integer square lattice. This problem is the dual of the corresponding projection theorem, which was considered by Glasscock, and Lima and Moreira, with the mass and counting dimensions applied to subsets of $mathbb{Z}^{d}$. In this paper, more generally we deal with a subset of the plane that is $1$ separated, and the result for subsets of the integer lattice follow as a special case. We show that the natural slicing question in this setting is true with the mass dimension.

Khintchine-type theorems for values of subhomogeneous functions at integer points. (arXiv:1910.02067v2 [math.NT] UPDATED)

This work has been motivated by recent papers that quantify the density of values of generic quadratic forms and other polynomials at integer points, in particular ones that use Rogers' second moment estimates. In this paper we establish such results in a very general framework. Namely, given any subhomogeneous function (a notion to be defined) $f: mathbb{R}^n o mathbb{R}$, we derive a necessary and sufficient condition on the approximating function $psi$ for guaranteeing that a generic element $fcirc g$ in the $G$-orbit of $f$ is $psi$-approximable; that is, $|fcirc g(mathbf{v})| le psi(|mathbf{v}|)$ for infinitely many $mathbf{v} in mathbb{Z}^n$. We also deduce a sufficient condition in the case of uniform approximation. Here, $G$ can be any closed subgroup of $operatorname{ASL}_n(mathbb{R})$ satisfying certain axioms that allow for the use of Rogers-type estimates.

Nonlinear stability of explicit self-similar solutions for the timelike extremal hypersurfaces in R^{1+3}. (arXiv:1907.01126v2 [math.AP] UPDATED)

This paper is devoted to the study of the singularity phenomenon of timelike extremal hypersurfaces in Minkowski spacetime $mathbb{R}^{1+3}$. We find that there are two explicit lightlike self-similar solutions to a graph representation of timelike extremal hypersurfaces in Minkowski spacetime $mathbb{R}^{1+3}$, the geometry of them are two spheres. The linear mode unstable of those lightlike self-similar solutions for the radially symmetric membranes equation is given. After that, we show those self-similar solutions of the radially symmetric membranes equation are nonlinearly stable inside a strictly proper subset of the backward lightcone. This means that the dynamical behavior of those two spheres is as attractors. Meanwhile, we overcome the double roots case (the theorem of Poincar'{e} can't be used) in solving the difference equation by construction of a Newton's polygon when we carry out the analysis of spectrum for the linear operator.

Extremal values of the Sackin balance index for rooted binary trees. (arXiv:1801.10418v5 [q-bio.PE] UPDATED)

Tree balance plays an important role in different research areas like theoretical computer science and mathematical phylogenetics. For example, it has long been known that under the Yule model, a pure birth process, imbalanced trees are more likely than balanced ones. Therefore, different methods to measure the balance of trees were introduced. The Sackin index is one of the most frequently used measures for this purpose. In many contexts, statements about the minimal and maximal values of this index have been discussed, but formal proofs have never been provided. Moreover, while the number of trees with maximal Sackin index as well as the number of trees with minimal Sackin index when the number of leaves is a power of 2 are relatively easy to understand, the number of trees with minimal Sackin index for all other numbers of leaves was completely unknown. In this manuscript, we fully characterize trees with minimal and maximal Sackin index and also provide formulas to explicitly calculate the number of such trees.

SCAttNet: Semantic Segmentation Network with Spatial and Channel Attention Mechanism for High-Resolution Remote Sensing Images. (arXiv:1912.09121v2 [cs.CV] UPDATED)

High-resolution remote sensing images (HRRSIs) contain substantial ground object information, such as texture, shape, and spatial location. Semantic segmentation, which is an important task for element extraction, has been widely used in processing mass HRRSIs. However, HRRSIs often exhibit large intraclass variance and small interclass variance due to the diversity and complexity of ground objects, thereby bringing great challenges to a semantic segmentation task. In this paper, we propose a new end-to-end semantic segmentation network, which integrates lightweight spatial and channel attention modules that can refine features adaptively. We compare our method with several classic methods on the ISPRS Vaihingen and Potsdam datasets. Experimental results show that our method can achieve better semantic segmentation results. The source codes are available at https://github.com/lehaifeng/SCAttNet.

Establishing the Quantum Supremacy Frontier with a 281 Pflop/s Simulation. (arXiv:1905.00444v2 [quant-ph] UPDATED)

Noisy Intermediate-Scale Quantum (NISQ) computers are entering an era in which they can perform computational tasks beyond the capabilities of the most powerful classical computers, thereby achieving "Quantum Supremacy", a major milestone in quantum computing. NISQ Supremacy requires comparison with a state-of-the-art classical simulator. We report HPC simulations of hard random quantum circuits (RQC), which have been recently used as a benchmark for the first experimental demonstration of Quantum Supremacy, sustaining an average performance of 281 Pflop/s (true single precision) on Summit, currently the fastest supercomputer in the World. These simulations were carried out using qFlex, a tensor-network-based classical high-performance simulator of RQCs. Our results show an advantage of many orders of magnitude in energy consumption of NISQ devices over classical supercomputers. In addition, we propose a standard benchmark for NISQ computers based on qFlex.

GeoLogic -- Graphical interactive theorem prover for Euclidean geometry. (arXiv:2005.03586v1 [cs.LO])

Domain of mathematical logic in computers is dominated by automated theorem provers (ATP) and interactive theorem provers (ITP). Both of these are hard to access by AI from the human-imitation approach: ATPs often use human-unfriendly logical foundations while ITPs are meant for formalizing existing proofs rather than problem solving. We aim to create a simple human-friendly logical system for mathematical problem solving. We picked the case study of Euclidean geometry as it can be easily visualized, has simple logic, and yet potentially offers many high-school problems of various difficulty levels. To make the environment user friendly, we abandoned strict logic required by ITPs, allowing to infer topological facts from pictures. We present our system for Euclidean geometry, together with a graphical application GeoLogic, similar to GeoGebra, which allows users to interactively study and prove properties about the geometrical setup.

Conley's fundamental theorem for a class of hybrid systems. (arXiv:2005.03217v1 [math.DS])

We establish versions of Conley's (i) fundamental theorem and (ii) decomposition theorem for a broad class of hybrid dynamical systems. The hybrid version of (i) asserts that a globally-defined "hybrid complete Lyapunov function" exists for every hybrid system in this class. Motivated by mechanics and control settings where physical or engineered events cause abrupt changes in a system's governing dynamics, our results apply to a large class of Lagrangian hybrid systems (with impacts) studied extensively in the robotics literature. Viewed formally, these results generalize those of Conley and Franks for continuous-time and discrete-time dynamical systems, respectively, on metric spaces. However, we furnish specific examples illustrating how our statement of sufficient conditions represents merely an early step in the longer project of establishing what formal assumptions can and cannot endow hybrid systems models with the topologically well characterized partitions of limit behavior that make Conley's theory so valuable in those classical settings.

A Separation Theorem for Joint Sensor and Actuator Scheduling with Guaranteed Performance Bounds. (arXiv:2005.03143v1 [eess.SY])

We study the problem of jointly designing a sparse sensor and actuator schedule for linear dynamical systems while guaranteeing a control/estimation performance that approximates the fully sensed/actuated setting. We further prove a separation principle, showing that the problem can be decomposed into finding sensor and actuator schedules separately. However, it is shown that this problem cannot be efficiently solved or approximated in polynomial, or even quasi-polynomial time for time-invariant sensor/actuator schedules; instead, we develop deterministic polynomial-time algorithms for a time-varying sensor/actuator schedule with guaranteed approximation bounds. Our main result is to provide a polynomial-time joint actuator and sensor schedule that on average selects only a constant number of sensors and actuators at each time step, irrespective of the dimension of the system. The key idea is to sparsify the controllability and observability Gramians while providing approximation guarantees for Hankel singular values. This idea is inspired by recent results in theoretical computer science literature on sparsification.

A semantic diff that includes the difference between the failure state and at least one of an original state or a completion state is then computed. This semantic diff is transformed into a feature vector format. Then the transformed semantic diff is analyzed to determine a remediation for the update. Failure and/or resolution signatures can be constructed using the semantic diff and contextual data, and these signatures can be used in comparison and analysis of failures and resolutions.

I/O linking, TAP selection and multiplexer remove select control circuitry

Today many instances of IEEE 1149.1 Tap domains are included in integrated circuits (ICs). While all TAP domains may be serially connected on a scan path that is accessible external to the IC, it is generally preferred to have selectivity on which Tap domain or Tap domains are accessed. Therefore Tap domain selection circuitry may be included in ICs and placed in the scan path along with the Tap domains. Ideally, the Tap domain selection circuitry should only be present in the scan path when it is necessary to modify which Tap domains are selected in the scan path. The present disclosure describes a novel method and apparatus which allows the Tap domain selection circuitry to be removed from the scan path after it has been used to select Tap domains and to be replaced back into the scan path when it is necessary to select different Tap domains.

Method for stabilization and removal of radioactive waste and non hazardous waste contained in buried objects

A method and apparatus for the stabilization and safe removal of buried waste that is tested and classified as being transuranic or not transuranic waste and disposed accordingly. The buried waste (usually in vertical pipe units) is enclosed in a casing and ground and mixed with the surrounding soil. This process allows for chemical reactions to occur that stabilizes the mixture. The entire process is contained within the casing to avoid contamination. In situ or external testing is done for radio isotopes to classify the waste. If it is classified as transuranic the waste is removed in a controlled way into a retrieval enclosure and disposed off in drums. If the waste is not transuranic then grout is introduced into the mixture, allowed to set and the resulting monolith is removed and buried in trenches.

Managing safe removal of a passthrough device in a virtualization system

Methods and systems for managing a removal of a passthrough device from a guest managed by a hypervisor in virtualized computing environment. A hypervisor receives a request from the guest for access to a passthrough device. The hypervisor sets, in a memory, a last accessed state associated with a virtual machine executing the guest. The hypervisor forwards the request to the passthrough device and configures the host CPU to send a subsequent access request directly to the passthrough device. In response to a virtual machine reset, the hypervisor clears the last accessed state and instructs the host CPU to send a post-reset access request to the hypervisor.
