Adverse pregnancy outcomes (APOs) affect a large proportion of pregnancies and represent an important cause morbidity mortality worldwide. Yet the pathophysiology APOs is poorly understood, limiting our ability to prevent treat these conditions. To search for genetic markers maternal risk four APOs, we performed multi-ancestry genome-wide association studies (GWAS) loss, gestational length, diabetes, preeclampsia. We clustered participants by their ancestry focused analyses on three...
A four-port optical circulator based on two-dimensional square lattice photonic crystals is reported. It simple besides the brief framework. The crystalline geometrical structure of makes 90° non-reciprocal transmissions electromagnetic waves with low insertion loss and high levels isolation by diligence magneto-optic crystals. novel because it uses a resonant cavity design. Also, in comparison to prior models, proposed utilizes crystal cylindrical ferrite section π/4 Faraday angle. finite...
Machine Learning (ML), including Deep (DL), systems, i.e., those with ML capabilities, are pervasive in today's data-driven society. Such systems complex; they comprised of models and many subsystems that support learning processes. As other complex prone to classic technical debt issues, especially when such long-lived, but also exhibit specific these systems. Unfortunately, there is a gap knowledge how actually evolve maintained. In this paper, we fill by studying refactorings,...
In the aviation sector, ensuring safe landings while prioritizing safety of runways is crucial to prevent accidents and incidents during landing phase flights. However, many studies analyzing unsafe events, such as runway cracks or inadequate friction, often fail quantify their impacts on flight landing. airport pavement management systems (APMS), condition surface a critical factor in operational aircraft take-off Therefore, it essential provide pilots with reports conditions, including...
A dual-channel D-shaped photonic crystal fiber (PCF) based plasmonic sensor is proposed in this paper for the simultaneous detection of two different analytes using surface plasmon resonance (SPR) technique. The employs a 50 nm-thick layer chemically stable gold on both cleaved surfaces PCF to induce SPR effect. This configuration offers superior sensitivity and rapid response, making it highly effective sensing applications. Numerical investigations are conducted finite element method...
A reconfigurable surface-plasmon-based filter/sensor using D-shaped photonic crystal fiber is proposed. Initially a PCF designed and optimized to realize the highly birefringence by ensuring single polarization filter. tiny layer of silver placed on flat surface with small half-circular opening activate plasmon modes. By effect maximum confinement loss about 713 dB/cm realized at operating wavelength 1.98 µm in X-polarized mode. At this proposed only allows Y-polarization filters...

Abstract A photonic crystal (PhC) based optical component paves a path to the upcoming all-optical computer processors. All components can be realized with help of PhCs. In particular, gates have played major part in development half adders which has lead bloom computing technology. this paper, PhC adder is proposed and brief analysis carried out for different structures lattice patterns. The efficiency device analyzed by providing proper distinct space output power between logical ‘0’ ‘1’...
In this paper, a two-dimensional photonic crystal biosensor for medical applications based on two waveguides and nanocavity was explored with different shoulder-coupled structures. The most important parameters, like the sensitivity quality factor, can be significantly improved. By injecting an analyte into sensing hole, refractive index of hole changed. This senses changes shifts its operating wavelength accordingly. transmission characteristics light in under different indices that...
Abstract Photonic crystal fiber (PCF) based surface plasmon resonance (SPR) sensors are emerging as a promising technology for ultrasensitive detection of various biological and chemical analytes. This paper presents novel D-shaped PCF SPR sensor, which has shown great potential highly sensitive refractive index (RI) changes. The configuration is achieved through the polishing upper side fiber. To enhance sensitivity, 0.1 μ m silver layer strategically placed between analyte, intensifying...
Dynamic Traffic Assignment (DTA) plays a crucial role in the efficient management of traffic, as it is adaptable to changing conditions, such weather, accidents, and variations demand. However, conventional DTA algorithms tend be sluggish, which hinders their real-time effectiveness. Therefore, development faster imperative enable timely precise adjustments traffic assignment. This study outlines initial phases creating distributed multi-agent system designed handle dynamic scenarios. In...
