Laboratory Experiments of Model-based Reinforcement Learning for Adaptive Optics Control
(2024)arXivDirect imaging of Earth-like exoplanets is one of the most prominent scientific drivers of the next generation of ground-based telescopes. Typically, Earth-like exoplanets are located at small angular separations from their host stars, making their detection difficult. Consequently, the adaptive optics (AO) system's control algorithm must be carefully designed to distinguish the exoplanet from the residual light produced by the host ...Working Paper -
Experimental evaluation of bearingless spinfilter topologies
(2024)Separation and Purification TechnologyRotating filter membranes can increase the long term filtrate flux by efficiently and continuously removing the retained particles on a microfiltration membrane. However, the practical implementation of rotating machinery in high purity applications such as biotechnological manufacturing of proteins raises concerns about the contamination of the process fluids due to submerged bearings and imperfect sealings to the outside environment. ...Journal Article -
Machine learning for anomaly detection in particle physics
(2024)Reviews in PhysicsThe detection of out-of-distribution data points is a common task in particle physics. It is used for monitoring complex particle detectors or for identifying rare and unexpected events that may be indicative of new phenomena or physics beyond the Standard Model. Recent advances in Machine Learning for anomaly detection have encouraged the utilization of such techniques on particle physics problems. This review article provides an overview ...Review Article -
Recent Developments in Metallic Degradable Micromotors for Biomedical and Environmental Remediation Applications
(2024)Nano-Micro LettersSynthetic micromotor has gained substantial attention in biomedicine and environmental remediation. Metal-based degradable micromotor composed of magnesium (Mg), zinc (Zn), and iron (Fe) have promise due to their nontoxic fuel-free propulsion, favorable biocompatibility, and safe excretion of degradation products Recent advances in degradable metallic micromotor have shown their fast movement in complex biological media, efficient cargo ...Review Article -
Tumor targeted and GSH stimuli-response α‑lactalbumin nanotubes co-delivering doxorubicin and siRNA for cancer therapy
(2024)Journal of Future Foodsα-Lactalbumin (α-lac), a natural food-sourced protein, exhibits high biocompatibility as delivery systems for small bioactive molecules or RNA. However, their potential clinical application as a delivery system is greatly limited due to the lack of targeting to desired tissues, such as tumors. Here, a delivery system/nanocarrier of nanotube (NT) was fabricated by the self-assembly of peptides hydrolyzed from α-lac. Among the loading of ...Journal Article -
Bicycle as a traffic mode
(2024)Journal of Cycling and Micromobility ResearchCities allocate dedicated road space to bicycles in favor of active-mode road users. For urban environments with a mass bicycle volume, bicycle traffic congestion is likely to occur. Hence, a thorough understanding of bicycle traffic flow is necessary for the assessment of cycling infrastructure and the development of traffic management strategies considering cycling efficiency. This study aims to investigate bicycle flow characteristics ...Journal Article -
Comparative study on route choice models for cyclists
(2024)Journal of Cycling and Micromobility ResearchThis paper presents a comparison of different route choice models for cyclists. The data includes approx. 3,700 cycling trajectories. The network is derived based on the Open-Street-Map that contains street-level attribute information. We estimate two path-based and one link-based model. We present descriptive statistics, model results, resulting indicators, and compare different validation approaches. The results reveal important differences ...Journal Article -
Decentralized project delivery on the crypto commons: Conceptualization, governance mechanisms, and future research directions
(2024)Project Leadership and SocietyThis paper presents a first conceptualization for decentralized project delivery through the combination of blockchain technology and common pool resource governance theory, also known as the ”crypto commons”. While previous literature on project delivery models identifies the use of decentralized governance, there is not yet a holistic conceptualization nor a specific overview of governance applications that can be applied. To develop ...Journal Article -
Absolute dating of the European Neolithic using the 5259 BC rapid <sup>14</sup>C excursion
(2024)Nature CommunicationsAbrupt radiocarbon (14C) excursions, or Miyake events, in sequences of radiocarbon measurements from calendar-dated tree-rings provide opportunities to assign absolute calendar dates to undated wood samples from contexts across history and prehistory. Here, we report a tree-ring and 14C-dating study of the Neolithic site of Dispilio, Northern Greece, a waterlogged archaeological site on Lake Kastoria. Findings secure an absolute, ...Journal Article
