De-crackling Virtual Analog Controls with Asymptotically Stable Recurrent Neural Networks
Recurrent neural networks are used in virtual analog modeling applications to digitally replicate the sound of analog hardware audio processors. The controls of hardware devices can be used as a conditioning input to these networks. A common method for introducing control conditioning to these models is the direct static concatenation of controls with input audio samples, which we show produces audio artifacts under time-varied conditioning. Here we derive constraints for asymptotically stable …

Unfortunately CrossOver Preview seems to have gotten rid of the "Display Settings" sidebar on the right which let you simulate different display geometries than what wine auto-detected, which was very helpful for on-the-go #Steam gaming on #macOS on my MBP since rarely does it detect proper 16:10 or 16:9.
I used this, for example, with #BluePrince to ensure the left and right sides of the display were not cropped.
As an odd, but very workable, alternative solution - if you get the free edition of BetterDisplay and have it create a Virtual Display of the aspect ratio you want and then enable it, you can go into Settings -> Displays and configure your built-in display as a mirror for the virtual display.
The net result will be that it forces your only real display to conform to match the mirrored alternative geometry. Doesn't seem to be too much of a performance impact so far, but I haven't tried it with any super intense games either yet.

Measurement of the top-quark Yukawa coupling from $t\overline{t}$ production in the lepton+jets final state using $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector

GulliVR: A Walking-Oriented Technique for Navigation in Virtual Reality Games Based on Virtual Body Resizing
Virtual reality games are often centered around our feeling of "being there". That presence can be significantly enhanced by supporting physical walking. Although modern virtual reality systems enable room-scale motions, the size of our living rooms is not enough to explore vast virtual environments. Developers bypass that limitation by adding virtual navigation such as teleportation. Although such techniques are intended (or designed) to extend but not replace natural walking, what we often ob…

Impacts of Blade Camber on Cross-Flow Turbine Performance and Loading
Cross-flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross-flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance and loading, however there is little consensus regarding the direction of camber that might be most favorable. This study compares 2% concave-in and conca…

One solution to this disparity is to extend the available walking range by augmenting users' actual movements. However, the resulting increase in visual flow can easily cause cybersickness. Therefore, we present a novel augmented-walking approach for virtual reality games. Our core concept is a virtual tunnel that spans the entire travel distance when viewed from the outside.

Behavioral and Symbolic Fillers as Delay Mitigation for Embodied Conversational Agents in Virtual Reality
When communicating with embodied conversational agents (ECAs) in virtual reality, there might be delays in the responses of the agents lasting several seconds, for example, due to more extensive computations of the answers when large language models are used. Such delays might lead to unnatural or frustrating interactions. In this paper, we investigate filler types to mitigate these effects and lead to a more positive experience and perception of the agent. In a within-subject study, we asked 2…
