description: Adams spectral sequences have been an efficient tool in computing stable homotopy groups, classically and equivariantly. In Chapter 2 of this thesis, we explore the relationship between the classical Adams spectral sequences for stunted real projective spectra, the Borel C2-equivariant Adams spectral sequence for the 2-completed sphere, and the genuine C2-equivariant Adams spectral sequence for the 2-completed sphere. This allows us to understand the genuine C2-equivariant Adams spectral sequence from the Borel Adams spectral sequence. We show that the Borel Adams spectral sequence is computable as a classical Adams spectral sequence.
Given a fiber sequence with good properties, the geometric boundary theorem relates the connecting map in the long exact sequence of homotopy groups to the connecting homomorphism in the map between the E2-page of the Adams spectral sequences. This theorem was generalized by Behrens. In Chapter 3 of this thesis, we reformulate the generalized geometric boundary theorem to fix a mistake made by Behrens, and give a new proof using the language of filtered spectra.
A finite spectrum can be reassembled from its K(n)-localizations. While the homotopy groups of the K(2)-local sphere have been computed completely at odd primes, they are not fully understood at the prime 2. On the other hand, the K(2)-local homotopy groups of Z, a finite spectrum of type 2 with 32 cells, have been determined up to a possible extension. In Chapter 4 of this thesis, we compute an approximation of the K(2)-local homotopy groups of $Y_{\mathbb H}$ at the prime 2 using the algebraic duality spectral sequence and the topological duality spectral sequence, where $Y_{\mathbb H}\simeq\Sigma^{-7}\Sigma^\infty\mathbb{RP}^2\wedge\mathbb{CP}^2\wedge\mathbb{HP}^2$ is a finite spectrum of type 1 with 8 cells. We fully compute its algebraic duality spectral sequence. Furthermore, we construct a filtered duality spectral sequence, using which we compute the topological duality spectral sequence associated to $Y_{\mathbb H}$ up to some possible $d_3$-differentials.

description: The internal motion of partons inside hadrons has been studied through its impact on very low transverse momentum spectra of Drell-Yan (DY) pairs created in hadron-hadron collisions. We study DY production at next-to-leading order using the Parton Branching (PB) method which describes the evolution of transverse momentum dependent parton distributions. The main focus is on studying the intrinsic transverse momentum distribution (intrinsic-$k_T$) as a function of the center-of-mass energy $\sqrt s$. While collinear parton shower Monte Carlo event generators require intrinsic transverse momentum distributions strongly dependent on $\sqrt s$, this is not the case for the PB method. We perform a detailed study of the impact of soft parton emissions. We show that by requiring a minimal transverse momentum, $q_0$, of a radiated parton, a dependence of the width of the intrinsic-$k_T$ distribution as a function of $\sqrt{s}$ is observed. This dependence becomes stronger with increasing $q_0$.

description: Atmospheric neutrinos play a vital role in generating irreducible backgrounds in liquid-scintillator (LS) detectors via their neutral-current (NC) interactions with $^{12}$C nuclei. These interactions may affect a wide range of research areas from the MeV to GeV energy range, such as the reactor and geo neutrinos, diffuse supernova neutrino background (DSNB), dark matter, and nucleon decay searches. In this work, we extend our preceding paper, by conducting a first-time systematic exploration of NC backgrounds as low as the MeV region of reactor and geo neutrinos. We utilize up-to-date neutrino generator models from GENIE and NuWro, a TALYS-based nuclear deexcitation package and a GEANT4-based detector simulation toolkit for our complete calculation. Our primary focus is to predict the NC background for experimental searches of inverse-beta-decay signals below the 100 MeV visible energy. In order to have deeper understanding of the characteristics of atmospheric neutrino NC interactions in LS, we investigate the model dependence of NC background predictions by using various data-driven models, including the initial neutrino-nucleon interactions, nuclear ground-state structure, final-state interactions, nuclear deexcitation processes, and secondary interactions of final-state particles.

description: The third Gaia data release (DR3) contains $\sim$170\,000 astrometric orbit solutions of two-body systems located within $\sim$500 pc of the Sun. Determining component masses in these systems, in particular of stars hosting exoplanets, usually hinges on incorporating complementary observations in addition to the astrometry, e.g. spectroscopy and radial velocities. Several Gaia DR3 two-body systems with exoplanet, brown-dwarf, stellar, and black-hole components have been confirmed in this way. We developed an alternative machine learning approach that uses only the Gaia DR3 orbital solutions with the aim of identifying the best candidates for exoplanets and brown-dwarf companions. Based on confirmed substellar companions in the literature, we use semi-supervised anomaly detection methods in combination with extreme gradient boosting and random forest classifiers to determine likely low-mass outliers in the population of non-single sources. We employ and study feature importance to investigate the method's plausibility and produced a list of 20 best candidates of which two are exoplanet candidates and another five are either very-massive brown dwarfs or very-low mass stars. Three candidates, including one initial exoplanet candidate, correspond to false-positive solutions where longer-period binary star motion was fitted with a biased shorter-period orbit. We highlight nine candidates with brown-dwarf companions for preferential follow-up. The companion around the Sun-like star G\,15-6 could be confirmed as a genuine brown dwarf using external radial-velocity data. This new approach is a powerful complement to the traditional identification methods for substellar companions among Gaia astrometric orbits. It is particularly relevant in the context of Gaia DR4 and its expected exoplanet discovery yield.

description: We theoretically propose a polymer-based nano-device consisting of a single trans-polyacetylene (tPA) molecule capacitively coupled to external voltage gates. We model the integrated device using a Su-Schrieffer-Heeger (SSH)-like Hamiltonian, and we demonstrate the emergence of localized domain walls (DWs) with quantized charges (i.e., soliton excitations) localized at the gates. Interestingly, by increasing the applied voltage, multiple discrete charges can be accumulated, which may be useful for potential technological applications. Exploiting the topological character of the solitonic excitations of tPA, this device can be considered as an organic-based quantum dot with a very large and robust quantized charge.

description: In this study, we investigated the effects of self-reflection in large language models (LLMs) on problem-solving performance. We instructed nine popular LLMs to answer a series of multiple-choice questions to provide a performance baseline. For each incorrectly answered question, we instructed eight types of self-reflecting LLM agents to reflect on their mistakes and provide themselves with guidance to improve problem-solving. Then, using this guidance, each self-reflecting agent attempted to re-answer the same questions. Our results indicate that LLM agents are able to significantly improve their problem-solving performance through self-reflection ($p < 0.001$). In addition, we compared the various types of self-reflection to determine their individual contribution to performance.

description: Radio frequency antennas based on Rydberg atom vapor cells can in principle reach sensitivities beyond those of any wire antenna, especially at lower frequencies where long wires are needed to accommodate a growing wavelength. They also have other desirable features such as nonmetallic, lower profile, elements. This paper presents a detailed theoretical investigation of Rydberg antenna sensitivity, elucidating parameter regimes that could cumulatively lead to 2--3 orders of magnitude sensitivity increase beyond that of currently tested configurations. The key insight is to optimally combine the advantages of two well-studied approaches: (i) three laser ``2D star configuration'' setups that, enhanced also with increased laser power, help compensate for atom motion-induced Doppler broadening, and (ii) resonant coupling between a pair of near-degenerate Rydberg levels, tuned via a local oscillator to the incident signal. The advantage of the star setup is subtle because it only restores overall sensitivity to the expected Doppler-limited value, compensating for additional off-resonance reductions where differently moving atom populations destructively interfere with each other in the net signal. The additional unique advantage of the local oscillator tuning is that it leads to vastly narrower line widths, as low as ~10 kHz set by the intrinsic Rydberg state lifetimes, rather than the typical ~10 MHz set by the core state lifetimes. Intuitively, with this setup the two Rydberg states may be tuned to act as an independent high-q cavity, a point of view supported through a study of the frequency-dependence of the antenna resonant response. There are a number of practical experimental advances, especially larger ~1 cm laser beam widths, required to suppress various extrinsic line broadening effects and to fully exploit this cavity response.

description: One of the challenges of the high-power hybrid laser welding of thick steels is the sensitivity of the process of the process to manufacturing tolerances. This usually leads to a time-consuming preparation of the welding edges, such as milling. The study deals with the influence of the edge quality of milled and plasma-cut steel made of S355J2 with a wall thickness of 20 mm on the laser hybrid welded seam quality. Furthermore, the gap bridgeability and the tolerances towards edge misalignment was investigated. An AC magnet was used as backing support to prevent sagging and positioned under the workpiece, to generate an upwards directed electromagnetic pressure. The profiles of the edges and the gap on the top and root side were measured using a digital camera. Single-pass laser hybrid welds of plasma-cut edges could be welded using a laser beam power of just 13.7 kW. A gap bridgeability up to 2 mm and misalignment of edges up to 2 mm could be achieved successful. Additionally, the independence of the cutting side and the welding side was shown, so that samples were welded to the opposite side to their cutting. For evaluation of internal defects or irregularities, X-ray images were carried out. Charpy impact strength tests were performed to determine the toughness of the welds.

description: Here we present the discovery and characterization of the kagome metal TbTi$_3$Bi$_4$ in tandem with a new series of compounds, the Ln$_{2-x}$Ti$_{6+x}$Bi$_9$ (Ln: Tb-Lu) shurikagome metals. We previously reported on the growth of the LnTi$_3$Bi$_4$ (Ln: La-Gd$^{3+}$, Eu$^{2+}$, Yb$^{2+}$) family, a chemically diverse and exfoliable series of kagome metals with complex and highly anisotropic magnetism. However, unlike the La-Gd analogs, TbTi$_3$Bi$_4$ cannot be synthesized by our previous methodology due to phase competition with Ln$_{2-x}$Ti$_{6+x}$Bi$_9$ (x$\sim$1.7-1.2). Here we discuss the phase competition between the LnTi$_3$Bi$_4$ and Ln$_{2-x}$Ti$_{6+x}$Bi$_9$ families, helping to frame the difficulty in synthesizing LnTi$_3$Bi$_4$ compounds with small Ln species and providing a strategy to circumvent formation of Ln$_{2-x}$Ti$_{6+x}$Bi$_9$. Detailed characterization of the magnetic and electronic transport properties on single crystals of TbTi$_3$Bi$_4$ reveals a highly complex landscape of magnetic phases arising from an antiferromagnetic ground state. A series of metamagnetic transitions creates at least 5 unique magnetic phase pockets, including a 1/3 and 2/3 magnetization plateau. Further, the system exhibits an intimate connection between the magnetism and magnetotransport, exhibiting sharp switching from positive (+40%) to negative magnetoresistance (-50%). Like the LnTi$_3$Bi$_4$ kagome metals, the Ln$_{2-x}$Ti$_{6+x}$Bi$_9$ family exhibits quasi-2D networks of titanium and chains of rare-earth. We present the structures and some basic magnetic properties of the Ln$_{2-x}$Ti$_{6+x}$Bi$_9$ family alongside our characterization of the newly discovered TbTi$_3$Bi$_4$.

description: Two main mechanisms have classically been proposed for the formation of runaway stars. In the binary supernova scenario (BSS), a massive star in a binary explodes as a supernova, ejecting its companion. In the dynamical ejection scenario, a star is ejected during a strong dynamical encounter between multiple stars. We propose a third mechanism for the formation of runaway stars: the subcluster ejection scenario (SCES), where a subset of stars from an infalling subcluster is ejected out of the cluster via a tidal interaction with the contracting gravitational potential of the assembling cluster. We demonstrate the SCES in a star-by-star simulation of the formation of a young massive cluster from a $10^6\rm~M_\odot$ gas cloud using the Torch framework. This star cluster forms hierarchically through a sequence of subcluster mergers determined by the initial turbulent, spherical conditions of the gas. We find that these mergers drive the formation of runaway stars in our model. Late-forming subclusters fall into the central potential, where they are tidally disrupted, forming tidal tails of runaway stars that are distributed highly anisotropically. Runaways formed in the same SCES have similar ages, velocities, and ejection directions. Surveying observations, we identify several SCES candidate groups with anisotropic ejection directions. The SCES is capable of producing runaway binaries: two wide dynamical binaries in infalling subclusters were tightened through ejection. This allows for another velocity kick via subsequent via a subsequent BSS ejection. An SCES-BSS ejection is a possible avenue for the creation of hypervelocity stars unbound to the Galaxy. We expect nonspherical initial gas distributions to increase the number of calculated runaway stars. The observation of groups of runaway stars formed via the SCES can thus reveal the assembly history of their natal clusters.

description: This systematic review explores the role of novel endpoints in oncology trials, focusing on prognostic and predictive strategies, pharmacokinetic and pharmacodynamic modeling, survival outcome validation, and imaging-based metrics. Synthesized using Synthory.AI, the review incorporates findings from eight studies published between 2018 and 2025. Key insights include the transformative potential of targeted therapies in EGFR-mutated NSCLC, the promise of biomarker-driven approaches for epigenetic therapies, the predictive accuracy of surrogate endpoints in prostate and breast cancer, and the emerging utility of MRI volumetrics for survival prediction in NSCLC with brain metastases. While these advancements demonstrate significant progress, challenges such as limited generalizability and methodological variability remain. Future research should focus on standardization, diverse populations, and robust endpoint validation to optimize oncology trial outcomes.

description: A search in Scopus within "Article title, Abstract, Keywords" unveils 2,444 documents focused on the biomechanics of Abdominal Aortic Aneurysm (AAA), mostly on AAA wall stress. Only 24 documents investigated AAA kinematics, an important topic that could potentially offer significant insights into the biomechanics of AAA. In this paper, we present an image-based approach for patient-specific, in vivo, and non-invasive AAA kinematic analysis using patient's time-resolved 3D computed tomography angiography (4D-CTA) images, with an objective to measure wall displacement and strain during the cardiac cycle. Our approach relies on regularized deformable image registration for estimating wall displacement, estimation of the local wall strain as the ratio of its normal displacement to its local radius of curvature, and local surface fitting with non-deterministic outlier detection for estimating the wall radius of curvature. We verified our approach against synthetic ground truth image data created by warping a 3D-CTA image of AAA using a realistic displacement field obtained from a finite element biomechanical model. We applied our approach to assess AAA wall displacements and strains in ten patients. Our kinematic analysis results indicated that the 99th percentile of circumferential wall strain, among all patients, ranged from 2.62% to 5.54%, with an average of 4.45% and a standard deviation of 0.87%. We also observed that AAA wall strains are significantly lower than those of a healthy aorta. Our work demonstrates that the registration-based measurement of AAA wall displacements in the direction normal to the wall is sufficiently accurate to reliably estimate strain from these displacements.

description: The reliable generation of quasi-homogeneous autoignition inside a combustor fed by a continuous air flow would represent a milestone in realizing pressure gain combustion in gas turbines. In this work, the ignition distribution inside a stratified fuel–air mixture is analyzed. The ability of precise and reproducible injection of a desired fuel profile inside a convecting air flow is verified by applying tunable diode laser absorption spectroscopy in non-reacting measurements. High-speed, static pressure sensors and ionization probes allow for simultaneous detection of the flame and pressure rise at several axial positions in reactive measurements with dimethyl ether as fuel. A second, exchangeable combustion tube enables optical observation of OH* intensity in combination with pressure measurements. Experiments with three arbitrary fuel profiles show a set of ignition distributions that vary in shape, homogeneity, and the number of simultaneous autoignition events. Although the measurements show notable variation, a significant and reproducible influence of the fuel injection on the ignition distribution is observed. Results show that uniform autoignition leads to a coupling of the reaction front with the pressure rise and, therefore, induces a greater aerodynamic constraint than non-uniform ignition distributions, which are dominated by propagating deflagration fronts.

description: Ergodic quantum many-body systems evolving under unitary time dynamics typically lose memory of their initial state via information scrambling. Here we consider a paradigmatic translationally invariant many-body Hamiltonian of interacting bosons -- a Josephson junction array in the transmon regime -- in the presence of a strong Floquet drive. Generically, such a time-dependent drive is expected to heat the system to an effectively infinite temperature, featureless state in the late-time limit. However, using numerical exact-diagonalization we find evidence of special ratios of the drive amplitude and frequency where the system develops {\it emergent} conservation laws, and {\it approximate} integrability. Remarkably, at these same set of points, the Lyapunov exponent associated with the semi-classical dynamics for the coupled many-body equations of motion drops by orders of magnitude, arresting the growth of chaos. We supplement our numerical results with an analytical Floquet-Magnus expansion that includes higher-order corrections, and capture the slow dynamics that controls decay away from exact freezing.

description: The atomic layer deposition of gallium and indium oxide was investigated on mesoporous silica powder and compared to the related aluminum oxide process. The respective oxide (GaOx, InOx) was deposited using sequential dosing of trimethylgallium or trimethylindium and water at 150 °C. In-situ thermogravimetry provided direct insight into the growth rates and deposition behavior. The highly amorphous and well-dispersed nature of the oxides was shown by XRD and STEM EDX-mappings. N2 sorption analysis revealed that both ALD processes resulted in high specific surface areas while maintaining the pore structure. The stoichiometry of GaOx and InOx was suggested by thermogravimetry and confirmed by XPS. FTIR and solid-state NMR were conducted to investigate the ligand deposition behavior and thermogravimetric data helped estimate the layer thicknesses. Finally, this study provides a deeper understanding of ALD on powder substrates and enables the precise synthesis of high surface area metal oxides for catalytic applications.

description: Künstliche Intelligenz avanciert zu einem zentralen Thema der Debatten um eine übergreifende Digitalisierung der Arbeitswelt. Insgesamt zeigt sich dabei eine Dominanz wirtschaftlicher Perspektiven auf KI: so wird KI oft anhand ökonomischer Prognosen in Bezug auf Beschäftigung diskutiert. Andererseits finden sich auch Annahmen zu Auswirkungen auf Tätigkeiten im konkreten Arbeitsprozess. Einigkeit herrscht scheinbar darüber, dass KI umfangreiche Veränderungen in den Betrieben bewirken wird. Der Beitrag widmet sich im Sinne eines Positionspapiers diesem Spannungsfeld zwischen dominanten, diskursiven Erwartungen und empirischer, betrieblicher Realität von KI in Deutschland. Hierfür werden zentrale Perspektiven auf KI in Bezug auf Beschäftigung und Tätigkeiten vorgestellt und mit der vorhandenen Empirie zum Thema abgeglichen. Dadurch lassen sich die vorherrschenden Leitbilder und Spekulationen der KI Debatte besser einordnen. Die Sammlung der Empirie offenbart eklatante Forschungslücken hinsichtlich quantitativer als auch qualitativer Forschung zur Nutzung, als auch zum Einfluss von KI auf Arbeit. Zudem zeigen sich Schwierigkeiten bezüglich der Operationalisierung des Begriffs. Der Artikel bietet abschließend Überlegungen zu einem detaillierteren Verständnis von KI und zeigt Anknüpfungspunkte für künftige Forschung auf.
description: Artificial intelligence has recently become a central topic again in debates on the comprehensive digitalization of the world of work. Overall, the debate is dominated by economic perspectives on AI: AI is often discussed on the basis of economic forecasts concerning employment. On the other hand, there are also assumptions about the effects on tasks in the actual work process. There seems to be a consensus that AI will cause extensive changes in workplaces. This paper is dealing with the tensions between the dominant, discursive expectations and the empirical, workplace reality of AI in Germany. For this purpose, central perspectives on AI with regard to employment and tasks are presented and compared to the existing empirical data on the topic. This allows for a better understanding of the dominant leading images and speculations of the AI debate. The review of the empirical evidence reveals major gaps in quantitative and qualitative research on the application and the impact of AI on work. In addition, difficulties regarding the operationalization of the term become clear. The article offers final considerations for a deeper understanding of AI and identifies linkages for future research.

description: While laser sintering (LS) processes are typically optimised towards denser powder beds, our approach is different as we investigate the use of non-dense powder beds made of porous composite powder materials of polylactide-co-glycolide (PLGA) and bioactive glass (BG) 45S5. Powders were produced via solid-in-oil-in-water emulsion with modified BG as porogen and changing PLGA:BG ratios with up to 50 wt% of BG. Characterisation was done using scanning electron microscope (SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray fluorescence (XRF), thermal gravimetric analysis (TG), powder packing and flow, particle-size distribution (PSD) and X-ray tomography. The microparticles showed varying degrees of sphericity, porosity and specific surface area (SSA), while the BG porogen could be incorporated into or onto the foamed polymer. Powders were used for LS and gave parts with an overall porosity of ~ 75%. Our special approach might be interesting for multi-material LS for real biomimetic scaffolds with tailored hierarchical pore structures.

description: Local moments with a spin $S>1/2$ can exhibit a rich variety of elementary quasiparticle excitations, such as quadrupolar excitations, that go beyond the dipolar magnons of conventional spin-$1/2$ systems. However, the experimental observation of such quadrupolar excitations is often challenging due to the dipolar selection rules of many linear response probes, rendering them invisible. Here we show that non-linear spectroscopy, in the form of two-dimensional coherent spectroscopy (2DCS), can be used to reveal quadrupolar excitations. Considering a family of spin-1 Heisenberg ferromagnets with single-ion easy-axis anisotropy as an example, we explicitly calculate their 2DCS signature by combining exact diagonalization and generalized spin wave theory. We further demonstrate that 2DCS can provide access to the quadrupolar weight of an excitation, analogous to how linear response provides access to the dipolar weight. Our work highlights the potential of non-linear spectroscopy as a powerful tool to diagnose multipolar excitations in quantum magnets.

description: Image quality assessment (IQA) is indispensable in clinical practice to ensure high standards, as well as in the development stage of machine learning algorithms that operate on medical images. The popular full reference (FR) IQA measures PSNR and SSIM are known and tested for working successfully in many natural imaging tasks, but discrepancies in medical scenarios have been reported in the literature, highlighting the gap between development and actual clinical application. Such inconsistencies are not surprising, as medical images have very different properties than natural images, and PSNR and SSIM have neither been targeted nor properly tested for medical images. This may cause unforeseen problems in clinical applications due to wrong judgment of novel methods. This paper provides a structured and comprehensive overview of examples where PSNR and SSIM prove to be unsuitable for the assessment of novel algorithms using different kinds of medical images, including real-world MRI, CT, OCT, X-Ray, digital pathology and photoacoustic imaging data. Therefore, improvement is urgently needed in particular in this era of AI to increase reliability and explainability in machine learning for medical imaging and beyond. Lastly, we will provide ideas for future research as well as suggesting guidelines for the usage of FR-IQA measures applied to medical images.
