Detection of Legionella Bacteria Using a Silicon‐Based Photonic Microring Resonator Biosensor Enhanced by Dielectrophoresis

Silicon-based photonic biosensors, such as microring resonators and Mach-Zehnder interferometers, offer label-free detection, high sensitivity, and full compatibility with semiconductor fabrication processes. Yet, the detection of living bacteria remains difficult due to the limi...

Light‐Assisted Sub‐Coercive Ferroelectric Programming for Reconfigurable In‐Sensor Logic

ABSTRACT Reconfigurable optoelectronic logic devices are attractive for in‐sensor computing, yet their practical deployment is often hindered either by structurally complex heterostructures or by the limited reconfigurability of simple single‐material platforms. Here, we report l...

Universal physics-informed machine learning framework for the prediction of porosity defects in high-power laser beam welding with different metallic materials

High-power laser beam welding (LBW) is a widely used joining technique for metallic materials. However, porosity defects frequently arise during the process, leading to significant degradation of weld properties. Accurate prediction of porosity remains challenging due to the high...

LPV Updates for Sequentially Linearized Moving Horizon Estimation of Nonlinear Systems

ABSTRACT Moving horizon estimation (MHE) provides high‐precision state estimation for nonlinear systems, but it is often limited by the substantial computational demands of solving a nonlinear optimization problem at every sampling step. To address this issue, we develop an effic...

Partial Observation of Linear Systems With the Mori–Zwanzig Formalism

ABSTRACT The Mori–Zwanzig (MZ) formalism provides a systematic framework for deriving reduced‐order model of dynamical systems when only part of the state is observed, but its practical use is often limited by the complexity of the resulting computations. This paper develops an e...

Distributed Optimization Under Uncertainty: A Cross-Paradigm Review and Future Directions

Due to its significant importance in many disciplines, distributed optimization under uncertainty has become an active research field over the past decade. This paper presents a cross-paradigm review of this development. We organize the literature around three approaches ordered...

"Rent a Data Steward" - A Lasting Model for Cross-Institutional Research Data Management Support?

This poster illustrates the evolution of the pilot project "Rent a Data Steward" (2023–2026) of the Thuringian Competence Network for Research Data Management and reflects on its learnings, achievements and limitations. It will be presented at the Fellowship of the Data 2026 and...

A Surface-Energy-Based Extension of the Cox–Krenchel Model for Stiffness Prediction of Short-Fiber-Reinforced Thermoplastics

Short-fiber-reinforced thermoplastics are widely used in lightweight structural applications, but reliable prediction of their Young’s modulus remains challenging because classical analytical models usually neglect interfacial effects. In this study, the Cox–Krenchel model was ex...

On non-negative operators in Krein spaces and their perturbations

Abstract One of the most important contributions of Heinz Langer in the area of operator theory in Krein spaces is the introduction of the notion of definitizable operators and the construction of the corresponding spectral function. In this note we obtain a new characterization...

Influence of mass transport near parallel band pumping electrodes and walls on the fate of chemical species in a sample plug introduced onto a redox-magnetohydrodynamics microfluidics chip

Abstract A 3D finite element model is used to investigate the behavior of a small sample volume of molecules inside a redox-magnetohydrodynamics (R-MHD) microfluidic chamber (3.0 cm × 1.7 cm, 429 µm-high), enclosing chip-based, coplanar parallel-band electrodes ( ~ 900 µm wide, 1...

High-throughput screening and mechanistic insights into solid acid proton conductors

Abstract Proton-conducting solid acids could enable water-free operation of high-temperature fuel cells. However, systematic materials screening has, hitherto, been computationally prohibitive. Here, we introduce a two-stage high-throughput screening strategy that directly comput...

Strong and Weak Quantitative Estimates in Slow-Fast Diffusions Using Filtering Techniques

Abstract. The behavior of slow-fast diffusions as the separation of scale diverges is a well-studied problem in the literature. In this short paper, we revisit this problem and obtain a new proof of existing strong quantitative convergence estimates (in particular, [Formula: see...

C60 Fullerene Promotes Restoration of Kidney Function After Chronic Glyphosate Intoxication

Glyphosate is one of the most widely used herbicides in modern agriculture. Toxicological studies have demonstrated that chronic glyphosate exposure is associated with the development of systemic disorders, particularly renal injury. Therefore, the search for effective therapeuti...
