JPMorgan Chase untersucht, ob Künstliche Intelligenz nicht nur bei der Aktienauswahl oder dem Risikomanagement helfen, sondern auch selbst Kapital allokieren kann.

Mientras los inversionistas recurren cada vez más a la inteligencia artificial para tareas como seleccionar acciones o gestionar riesgos, JPMorgan Chase & Co. está probando si esta tecnología también puede tomar una decisión mucho más trascendental: asignar capital entre distintas clases de activos.

This Reprint presents a curated collection of ten original research and review articles published in the Special Issue Recent Advancement in Microwave Photonics of the journal Photonics. It provides an overview of recent theoretical advances and practical applications in microwave photonics, a field that combines microwave engineering and photonics to address key limitations of conventional electronic systems, including limited bandwidth, high transmission loss, and electromagnetic interference.The contributions within this Reprint span various dimensions, from fundamental photonic integrated components to advanced system-level implementations. At the device level, high-performance silicon nitride (SiN) bent waveguides with modified Hermite curves, high-power silicon-based spot-size converters, and ultra-compact multimode micro-racetrack resonators are explored. Design innovations using B-spline curves and inverse design methods are highlighted to improve couplers and filters. At the system level, this Reprint investigates high-sensitivity microwave phase noise analyzers, frequency-stabilized optoelectronic oscillators (OEOs), and the integration of microwave photonics in radar systems for improved resolution and precision.

Using detailed timestamp data for patient visits and laboratory test orders from the emergency department (ED) of a large, urban, teaching hospital in the United States, we examine the operational effectiveness of the full capacity protocol (FCP), a set of temporary hospital-wide guidelines that seek to alleviate crowding at the ED. We use an instrumented difference-in-differences approach and construct a comparable treatment group prior to the introduction of the FCP. Our results indicate that the FCP is effective in reducing the patient length of stay (LOS) when activated. Patients who arrived when the FCP was activated experienced an estimated reduction in LOS of 6.23%. This reduction was achieved through shorter waiting and after-treatment times. The reduction in after-treatment time helped expedite access to the treatment area for waiting patients, alleviating the bottleneck and improving the throughput, consistent with the theory of swift even flow and the theory of constraints. We also find an inverted-U-shaped relationship between boarding census and after-treatment time when the FCP was on, a pattern not observed under similar crowding levels when the FCP was not on.
