Navigation and positioning technology is closely related to our routine life activities, from travel aerospace. Recently it has been found that Cataglyphis (a kind of desert ant) able detect the polarization direction skylight navigate according this information. This paper presents a real-time bionic camera-based navigation sensor. sensor two work modes: one single-point measurement mode other multi-point mode. An indoor calibration experiment done under beam standard polarized light. The...
This paper proposes an accuracy enhancement method for the fiber-longitudinal power profile estimation (PPE) based on convolutional neural networks (CNN). Two types of CNNs are designed. The first one is a network that treats different polarization streams identically. denoted as CNN. second considers difference between contributions to nonlinear phase shift and enhanced CNN (ECNN). numerical simulation results confirm effectiveness 64 GBaud/s DP-QPSK system with fiber length 320 km. effects...
Whether to deploy left-turn waiting areas (LTWAs) in arterial coordination remains debated as the required fixed phasing sequences may constrain signal flexibility. To fill this gap, a Vissim-based corridor synchronisation performance tool (V-CSPT) was developed based on timing measure methodology evaluate impacts of LTWAs coordination. This enables collection vehicle trajectories from microscopic traffic simulation software, facilitating analysis and evaluation. assess coordination, case...
The purpose was to investigate how well age-adjusted modified quick Sequential Organ Failure Assessment (qSOFA) scores paired with blood glucose and lactate levels predict the outcomes of septicemic children in pediatric intensive care unit (PICU). One hundred who were diagnosed sepsis septic shock PICU Henan Children's Hospital eligible, other 20 patients same hospital at different times selected as a validation set. Respiratory rate (RR), heart (HR), capillary refill time (CRT), Alert,...
Abstract Background Influenza is a contagious respiratory disease posing huge burden of for children around the world. The purpose this study was to investigate epidemiologic changes in childhood influenza Zhengzhou, China, before, during, and after COVID-19 outbreak. aim determine impact outbreak related prevention control policies on children’s epidemiological trend. Methods All report card data from Children’s Hospital Affiliated with Zhengzhou University’s Disease Surveillance Reporting...
Simultaneous localization and mapping is a mobile robot positioning themselves creating the map of environment at same time, which core problem vehicle achieve authentic intelligent. EKF-SLAM widely used SLAM algorithm based on extended Kaiman Alter. The proposed in this paper differential model motion, consider trajectory as many small straight Une segments. effectively reduce error compared with dead reckoning has more simplified generic kinematics model. Meanwhile, it lower requirements...
This paper compares queue lengths at the two different on-ramp configurations: arterial-to-freeway ramp and freeway-to-freeway connector. Mesoscopic length simulation models are developed based on input-output method. The method aims to model traffic flow arrival profile; then, mesoscopic generates random volume simulate stochasticity of flow. validated using field-collected data. Simulation results indicated that pattern has significant impacts length; vehicle platoons released from...
The ability to navigate in complex environments is crucial for both animals and mobile robots. Most robots adopt dead reckoning navigation because of its high efficiency low cost. In order use this mechanism, distance information directional must be available. research, a real-time three-channel camera-based polarization sensor developed provide robot navigation. accuracy the can kept within 0.3 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML"...

Surveillance of antibiotic use one the cornerstones to assess quality and plan impact stewardship interventions. Methods: We carried out quarterly point prevalence surveys referring WHO Methodology Point Prevalence Survey 16 Chinese general children’s hospitals 2019 inpatients based on AWaRe metrics detect potential areas. Data were retrieved via hospital information systems second Monday...
It is essential to design an appropriate submarine cable route reduce costs and improve reliability. A methodology that can be used for multi-objective optimization in planning proposed numerically studied this paper. The risks are assessed mapped the geographical map. pheromone heuristic functions of ant colony (ACO) algorithm associated with map risks, which enables it search a optimization. results show designed by effectively avoid high-cost high-risk regions, means cost-effective highly
E. coli L-asparaginase was modified with N, O-carboxymehtyl chitosan in the presence of normal product L-aspartic acid, which protected active site enzyme. The enzyme remained high catalytic activity, showed greater stability against trypsin and α-chymotrypsin, but lost its activity more rapidly at temperature (>45 °C) than did native When tested vivo, plasma half-life (t1/2 = 40 hr) over 33 times longer that 1.6 hr). results may be much useful for clinical treatments tumors.
In this letter, the modulation and demodulation mechanisms of discrete Fourier transform-based optical fast orthogonal frequency-division multiplexing (F-OFDM) scheme have been examined. Analysis shows that there exists an interference term between even odd subcarriers in F-OFDM scheme, which has severe impact on system performance, especially when subcarrier number is small. We propose a zero-subcarrier-based method numerically investigate effectiveness with different subcarriers....
Summary Freeway‐to‐freeway connector metering is a cost‐effective and proven freeway management strategy for relieving recurrent congestion. However, one of the critical challenges in design operation freeway‐to‐freeway lack up‐to‐date queue storage length guidance. In this study, it was found that ramp dynamically related to rate, on‐ramp demand, traffic flow arrival pattern. Hence, simply using an average demand cannot provide accurate estimation also not suitable where maximum or...
Probabilistic yielding is a commonly observed behavior at permissive left-turn signalized intersections in some developing countries, which has been studied the past to reveal its effect on traffic capacity. However, delay still unrevealed and requires further investigation. Different from method established for investigating capacity, most challenging issue studying recognition of queued non-queued vehicles. Based queuing theory, an analytical estimation model was developed this paper,...
