Reformulating Parallel-Connected Lithium-Ion Battery Pack Dynamics with Interconnection Resistances as Ordinary Differential Equations
This work presents analytical solutions for the current distribution in lithium-ion battery packs composed of cells connected in parallel, explicitly accounting for the presence of interconnection resistances. These solutions enable the reformulation of the differential-algebraic equations describing the pack dynamics into a set of ordinary differential equations, thereby simplifying simulation and analysis. Conditions under which uniform current sharing across all cells occurs are also derived…

Soziologe Nils Kumkar sagt hier kluge Sachen. Unter anderem, dass die Spaltung der Gesellschaft nicht so eindeutig ist, wie man immer denkt - denn jede*r verortet sie anders. Wir tragen also alle unsere eigene Spaltung der Gesellschaft mit uns herum. (1)

Feindbilder und Filterblase - Wo ist unsere Toleranz?

Alles persönlich nehmen, sofort zurückschießen – so verlaufen viele Debatten im Netz und im Alltag. Respekt und Rücksicht weichen schnellen Reaktionen und scharfen Worten. Doch wie klar darf Sprache sein? Wo endet Kritik und wo beginnt Krawall? #Gereizt #Streitkultur

Im gereizten Zeitalter – verlernen wir, respektvoll zu diskutieren?

TDoA-Based Self-Supervised Channel Charting with NLoS Mitigation
Channel Charting (CC) has emerged as a promising framework for data-driven radio localization, yet existing approaches often struggle to scale globally and to handle the distortions introduced by non-line-of-sight (NLoS) conditions. In this work, we propose a novel CC method that leverages Channel Impulse Response (CIR) data enriched with practical features such as Time Difference of Arrival (TDoA) and Transmission Reception Point (TRP) locations, enabling a self-supervised localization functio…

scellop: A Scalable Redesign of Cell Population Plots for Single-Cell Data
Summary: Cell population plots are visualizations showing cell population distributions in biological samples with single-cell data, traditionally shown with stacked bar charts. Here, we address issues with this approach, particularly its limited scalability with increasing number of cell types and samples, and present scellop, a novel interactive cell population viewer combining visual encodings optimized for common user tasks in studying populations of cells across samples or conditions. Av…

Probability distribution reconstruction using circuit cutting applied to a variational classifier
Significant efforts are being spent on building a quantum computer. At the same time, developments in quantum software are rapidly progressing. Insufficient quantum resources often are the problem when running quantum algorithms. New techniques can aid in using smaller quantum computers to run larger quantum algorithms. One of these techniques is circuit cutting. With this method, a circuit is broken into multiple pieces, each of which is run on quantum hardware independently and then recombine…

Besting Good--Turing: Optimality of Non-Parametric Maximum Likelihood for Distribution Estimation
When faced with a small sample from a large universe of possible outcomes, scientists often turn to the venerable Good--Turing estimator. Despite its pedigree, however, this estimator comes with considerable drawbacks, such as the need to hand-tune smoothing parameters and the lack of a precise optimality guarantee. We introduce a parameter-free estimator that bests Good--Turing in both theory and practice. Our method marries two classic ideas, namely Robbins's empirical Bayes and Kiefer--Wolfo…

The cubic NLS on the line with an inverse square potential
We establish modified scattering for solutions of the cubic NLS on the line with a repulsive inverse square potential and small localized data. The method is based on a comparison between the free and distorted Galilei vector fields and a wave packet transform.

Analysis of Broad Beam Beamforming for Collocated and Distributed MIMO
Broad beam beamforming (BF) design in multiple-input multiple-output (MIMO) can be convenient for initial access, synchronization, and sensing capabilities in cellular networks by avoiding overheads of sweeping methods while making efficient use of resources. Phase-only BF is key for maximizing power efficiency across antennas. A successful method to produce broad beams is the phase-only dual-polarization BF (DPBF). However, its efficiency has not been proved in non-line-of-sight (NLoS). Theref…

Digitalisierung diskutieren viele, doch wenig klar bleibt: Digitale Souveränität ist keine nettes Extra, sondern Überlebensfrage für Staat und Gesellschaft. Der Staat muss seine Handlungsfreiheit sichern – und das heißt auch, Lieferketten, Datenschutz und Infrastruktur robust zu gestalten. Wer das vernachlässigt, verliert am Ende mehr als nur Daten.

Ohne die nötigen digitalen Fähigkeiten ist ein Staat heute nicht mehr souverän. Was es braucht, um Deutschland gegen Angriffe zu wappnen und besser zu schützen.
