Planetesimal Scattering Efficiency of Cold Giant Planet Architectures
The discovery of many exoplanets has revealed an incredible diversity of orbital architectures. These orbital configurations are intrinsically linked to the potential for habitable environments within the system, since the gravitational influence of the planets governs the angular momentum distribution within the system. This angular momentum distribution, in turn, alters the planetary orbits and rotational obliquities. In the case of giant planets, their gravitational influence can also produc…

Recovering Exact Vibrational Energies Within a Phase Space Electronic Structure Framework
In recent years, there has been a push to go beyond Born-Oppenheimer theory and build electronic states from a phase space perspective, i.e. parameterize electronic states by both nuclear position(R) and nuclear momentum(P). Previous empirical studies have demonstrated that such approaches can yield improved single-surface observables, including vibrational energies, electronic momenta, and vibrational circular dichroism spectra. That being said, unlike the case of BO theory, there is no unique…

Unfortunately & conversely, this (below) is the same framing tech bros (and parts of the population) are finding so attractive to anthropomorphize LLMs: These are not machines, and them making mistakes is normal and expected... At the same time, the other card being played (by politics, military & law enforcement) is that AI-driven insights and decision making are _already_ considered superior, infallible and unchallengeable... in the middle of this two pronged rhetoric is the fate o…

Imprints of Different Types of Low-Angular-Momentum Accretion Flow Solutions in General Relativistic Hydrodynamic Simulations
Depending on the astrophysical source and its environment, the accretion flows can exhibit a variety of behaviors and characteristics in accordance with the type of solutions. We study low-angular-momentum accretion flows onto black holes using two-dimensional general relativistic hydrodynamic (GRHD) simulations to find imprints of different types of accretion solutions. Such flows, relevant to X-ray binaries and wind-fed low-luminosity active galactic nuclei, often lack sufficient angular mome…

Wadephul wirft Putin fehlende Verhandlungsbereitschaft vor
Außenminister Johann Wadephul hat Kremlchef Wladimir Putin im US-Fernsehen vorgeworfen, nicht bereit für ein Ende des Angriffskriegs gegen die Ukraine zu sein. "Alle sind für Verhandlungen. Alle sind dafür, dass die beiden Parteien eine einvernehmliche Lösung finden. Aber im Moment ist Russland dazu nicht bereit (...)", sagte der CDU-Politiker im Interview mit dem US-…

Divide-Fuse-Conquer: Eliciting "Aha Moments" in Multi-Scenario Games
Large language models (LLMs) have been observed to suddenly exhibit advanced reasoning abilities during reinforcement learning (RL), resembling an ``aha moment'' triggered by simple outcome-based rewards. While RL has proven effective in eliciting such breakthroughs in tasks involving mathematics, coding, and vision, it faces significant challenges in multi-scenario games. The diversity of game rules, interaction modes, and environmental complexities often leads to policies that perform well in…

De-Biasing Structure Function Estimates From Sparse Time Series of the Solar Wind: A Data-Driven Approach
Structure functions, which represent the moments of the increments of a stochastic process, are essential complementary statistics to power spectra for analysing the self-similar behaviour of a time series. However, many real-world environmental datasets, such as those collected by spacecraft monitoring the solar wind, contain gaps, which inevitably corrupt the statistics. The nature of this corruption for structure functions remains poorly understood - indeed, often overlooked. Here we simulat…

(Accelerated) Noise-adaptive Stochastic Heavy-Ball Momentum
Stochastic heavy ball momentum (SHB) is commonly used to train machine learning models, and often provides empirical improvements over stochastic gradient descent. By primarily focusing on strongly-convex quadratics, we aim to better understand the theoretical advantage of SHB and subsequently improve the method. For strongly-convex quadratics, Kidambi et al. (2018) show that SHB (with a mini-batch of size $1$) cannot attain accelerated convergence, and hence has no theoretical benefit over SGD…
