Abstract Background In clinical medicine, fetal heart rate (FHR) monitoring using cardiotocography (CTG) is one of the most commonly used methods for assessing acidosis. However, as visual interpretation CTG depends on subjective judgment clinician, this has led to high inter-observer and intra-observer variability, making it necessary introduce automated diagnostic techniques. Methods study, we propose a computer-aided algorithm (Hybrid-FHR) acidosis assist physicians in objective decisions...
An electrochemical (EC) method has been successfully applied to regulate the optical properties of nanocrystals, such as reducing their gain threshold by EC doping and enhancing photoluminescence intensity filling trap states. However, processes are rarely reported simultaneously in a single study, hindering understanding underlying interactions. Here, we report spectroelectrochemical (SEC) studies quasi-two-dimensional nanoplatelets (NPLs), intending clarify above issues. is achieved...
Because of their excellent optical and electrical properties, doped carbon quantum dots (CQDs) are expected to be used in novel film optoelectronic devices such as light-emitting diodes solar cells. However, these device advancements currently hindered by the elusive photophysical process CQDs solid-state films. Here, properties nitrogen-doped CQD (N-CQD) films studied using spectro-electrochemical (SEC) methods. A distinctive photoluminescence (PL) enhancement phenomenon is observed, which...
The random telegraph signal noise in the pixel source follower MOSFET is principle component of CMOS image sensor under low light. In this paper, physical and statistical model based on binomial distribution set up. number electrons captured or released by oxide traps unit time described as variables which obey distribution. As a result, output states corresponding probabilities first second samples correlated double sampling circuit are acquired. standard deviation after can be obtained...
We introduce an approach for creating optical filters with narrow bandwidth and high transmittance within the visible light spectrum. By combining interferometric properties of film system diffraction sub-wavelength grating, we have designed a bandpass filter based two-dimensional subwavelength metal grating structure Al2O3-air bilayer coating. The coating not only suppresses random scattering leakage in short-wavelength range but also maintains relative stability central wavelength...
In this study, we propose a novel approach to achieve an ultra-narrow bandwidth and high transmittance filter in the visible range.

Full well capacity (FWC) modeling has been widely used to clarify the imaging characteristics of pinned photodiode (PPD) in complementary metal-oxide-semiconductor (CMOS) image sensors. Until now, FWC considered only effects temperature, doping, and photon dependence on FWC. However, influence distribution interface trap-state energy levels is ignored. Therefore, this article proposes a dynamic model that depends energy-level trap states PPD for first time. By establishing 2-D function...
Dark count is one of the inherent noise types in single-photon diodes, which may restrict performances detectors based on these diodes. To formulate better designs for peripheral circuits such an accurate statistical behavioral model dark current must be established. Research has shown that there are four main mechanisms contribute to avalanche However, existing models only three have been considered, thus leading inaccuracies models. resolve shortcomings, caused by carrier diffusion neutral...
The optical gradient force distributions in focal plane of cosh-Gaussian beams with sine-azimuthal variation wavefront and half space phase modulation were investigated. Results show that can be affected considerably by the retardation half-space modulation, a parameter indicates change frequency on an increasing azimuthal angle, beam parameters cosh terms incident beams. Many patterns occur, including cross-shape, multiple trap arrays, multiple-trap wheel, many kinds lines curves. Symmetry...
