The underground “Jiangmen Underground #Neutrino Observatory" (JUNO) near Jiangmen city in the Guangdong Province has successfully completed the filling of its 20,000 tons of liquid scintillator and begun data taking: https://www.prisma.uni-mainz.de/outreach/press-releases/juno-completed-liquid-filling-and-begins-data-taking/ - JUNO will tackle one of this decade’s major open questions in particle physics, the ordering of neutrino masses i.e. whether the third mass state (ν₃) is heavier than the second (ν₂).

Optimal Control of ODE Car-Following Models: Applications to Mixed-Autonomy Platoon Control via Coupled Autonomous Vehicles
In this paper, we study the optimal control of a mixed-autonomy platoon driving on a single lane to smooth traffic flow. The platoon consists of autonomous vehicles, whose acceleration is controlled, and human-driven vehicles, whose behavior is described using a microscopic car-following model. We formulate the optimal control problem where the dynamics of the platoon are describing through a system of non-linear ODEs, with explicit constraints on both the state and the control variables. Theor…

Electromagnetic Formation Flying Using Alternating Magnetic Field Forces and Control Barrier Functions for State and Input Constraints
This article presents a feedback control algorithm for electromagnetic formation flying with constraints on the satellites' states and control inputs. The algorithm combines several key techniques. First, we use alternating magnetic field forces to decouple the electromagnetic forces between each pair of satellites in the formation. Each satellite's electromagnetic actuation system is driven by a sum of amplitude-modulated sinusoids, where amplitudes are controlled in order to prescribe the tim…

Der Zug von Hamburg nach Kiel, beziehungsweise nach Flensburg, wird immer in Neumünster geteilt. Für Menschen, die diese Verbindung das erste Mal nutzen, ist es wie ein Persönlichkeitstest. Die anderen Fahrgäst:innen können sehr klar erkennen, was für einen Typ Mensch vor einem steht. Und heute habe ich festgestellt, nicht zum ersten Mal, dass sich manche Menschen besser nicht reproduzieren sollten.

Optimal Hamiltonian for a quantum state with finite entropy
We consider the following task: how for a given quantum state $ρ$ to find a grounded Hamiltonian $H$ such that $\mathrm{Tr}Hρ\leq E_0<+\infty$ in such a way that the von Neumann entropy of the Gibbs state $γ_H(E)$ corresponding to a given energy $E>0$ be as small as possible. We show that for any mixed state $ρ$ with finite entropy and any $E>0$ there is a unique solution $H(ρ,E_0,E)$ of the above problem which we call optimal Hamiltonian for this state. Explicit expressions for $H(ρ,E_…

Topological phase transitions between bosonic and fermionic quantum Hall states near even-denominator filling factors
We study the quantum critical point between the fermionic $ν=8$ quantum Hall state and the bosonic $ν=2$ quantum Hall state of Cooper pairs. Our study is motivated by the composite fermion construction for the daughter states of even-denominator fractional quantum Hall states and the experimentally observed transition between the daughter and the Jain states at the same filling. We show that this transition is equivalent to the transition between a neutral invertible $E_8$ state and a topolog…

UltraMemV2: Memory Networks Scaling to 120B Parameters with Superior Long-Context Learning
While Mixture of Experts (MoE) models achieve remarkable efficiency by activating only subsets of parameters, they suffer from high memory access costs during inference. Memory-layer architectures offer an appealing alternative with very few memory access, but previous attempts like UltraMem have only matched the performance of 2-expert MoE models, falling significantly short of state-of-the-art 8-expert configurations. We present UltraMemV2, a redesigned memory-layer architecture that closes t…
