Open string field theory with stubs

Martin Schnabl, Georg Stettinger

There are various reasons why adding stubs to the vertices of open string field theory (OSFT) is interesting: Not only the stubs can tame certain singularities and make the theory…

Enhanced Radar Perception via Multi-Task Learning: Towards Refined Data for Sensor Fusion Applications

Huawei Sun, Hao Feng, Gianfranco Mauro +4

Radar and camera fusion yields robustness in perception tasks by leveraging the strength of both sensors. The typical extracted radar point cloud is 2D without height information d…

XD-RCDepth: Lightweight Radar-Camera Depth Estimation with Explainability-Aligned and Distribution-Aware Distillation

Huawei Sun, Zixu Wang, Xiangyuan Peng +4

Depth estimation remains central to autonomous driving, and radar-camera fusion offers robustness in adverse conditions by providing complementary geometric cues. In this paper, we…

More on stubs in open string field theory

Martin Schnabl, Georg Stettinger

We continue our analysis of open string field theory based on A-infinity-algebras obtained from Witten's theory by attaching stubs to the elementary vertex. Classical solutions of…

Search-Based Motion Planning for Performance Autonomous Driving

Zlatan Ajanovic, Enrico Regolin, Georg Stettinger +2

Driving on the limits of vehicle dynamics requires predictive planning of future vehicle states. In this work, a search-based motion planning is used to generate suitable reference…

Sliver frame stubs in OSFT via auxiliary fields

Georg Stettinger

In this short paper we want to generalize some recent concepts related to stubs in open string field theory. First, we modify the auxiliary field method by Erbin and Firat [#Erbin2…

What's Really Different with AI? -- A Behavior-based Perspective on System Safety for Automated Driving Systems

Marcus Nolte, Nayel Fabian Salem, Olaf Franke +4

Assuring safety for ``AI-based'' systems is one of the current challenges in safety engineering. For automated driving systems, in particular, further assurance challenges result f…

The BEF Symplectic Form: A Lagrangian Perspective

Mohd Ali, Georg Stettinger

In 2025, Bernardes, Erler and Firat proposed a novel, elegant expression for the symplectic form on phase space applicable to non-local theories. We show that this BEF symplectic s…

New massless and massive infinite derivative gravity in three dimensions

Anupam Mazumdar, Georg Stettinger

In this paper we will consider the most general quadratic curvature action with infinitely many covariant derivatives of massless gravity in three spacetime dimensions. The action…

Multi-Task Cross-Modality Attention-Fusion for 2D Object Detection

Huawei Sun, Hao Feng, Georg Stettinger +2

Accurate and robust object detection is critical for autonomous driving. Image-based detectors face difficulties caused by low visibility in adverse weather conditions. Thus, radar…

A boundary term for open string field theory

Georg Stettinger

We consider Witten's open string field theory in the presence of a non-trivial boundary of spacetime. For the kinetic term, we derive a Gibbons-Hawking-type contribution that has t…
