Exploring sex-specific neuroendocrine influences on the sensorimotor-association axis in single individuals
Human neuroimaging studies consistently show multimodal patterns of variability along a key principle of macroscale cortical organization – the sensorimotor-association (S-A) axis. However, little is known about day-to-day fluctuations in functional activity along this axis within an individual, including sex-specific neuroendocrine factors contributing to such transient changes.

Common neural dysfunction of economic decision-making across psychiatric conditions
Adaptive decision-making, which is often impaired in various psychiatric conditions, is essential for well-being. Recent evidence has indicated that decision-making capacity in multiple tasks could be accounted for by latent dimensions, enlightening the question of whether there is a common disruption of brain networks in economic decision-making across psychiatric conditions.

Homological Quantum Rotor Codes: Logical Qubits from Torsion
We formally define homological quantum rotor codes which use multiple quantum rotors to encode logical information. These codes generalize homological or CSS quantum codes for qubits or qudits, as well as linear oscillator codes which encode logical oscillators. [...]

Capacitive coupling in broadband spectral electrical impedance tomography (sEIT) measurements with a centralized multiplexer
The 7th international induced polarization workshop, LundLund, Sweden, 28 May 2024 - 30 May 20242024-05-282024-05-30 [10.34734/FZJ-2024-03389]
We analysed capacitive coupling in sEIT measurements associated with different cable types(shielded and unshielded) and measurement approaches (active and passive electrodes) using circuitmodels and actual sEIT field measurements. The modelling results showed the intricate trade-offsbetween wire-wire, wire-shield, and shield-soil capacitive coupling for shielded and unshieldedcables when using passive electrodes with a centralized multiplexer.

E-infrastructures deliver basic supercomputing and storage capabilities but can benefit from innovative higher-level services that enable use-cases in critical domains, such as environmental and agricultural science.This work describes methods to distribute virtual scenes to the GPU nodes of a modular supercomputer for data generation.High information density virtual scenes, containing >100k geometries, typically cannot be rendered in real-time without techniques that change the information content, such as level-of-detail or culling approaches.Our work enables the concurrent and partitioned coupling to the image analysis in such a way that the data generation is dynamic and can be allocated to GPU nodes on demand, resulting in the possibility of moving through a continuous virtual scene rendered on multiple nodes.Within agricultural data analysis, the approach is especially impactful as virtual fields contain many individual geometries that coexist in one continuous system.Our work facilitates the generation of high-quality image data sets which has the potential to solve the challenge of scarcity of well-annotated data in agricultural science.We use real-time communication standards to couple the data production with the image analysis training.We demonstrate how the use-case rendering impacts effective use of the compute nodes and furthermore develop techniques to distribute the workload to improve the data production..
