OBJECTIVE To assess the opinion of pediatric infectious disease (PID) specialists regarding the management of culture-negative acute hematogenous osteomyelitis. METHODS A questionnaire that included a hypothetical case scenario of a 4-year-old boy with culture-negative osteomyelitis was distributed via a Web-based system to PID specialists across the(More)
The knowledge-based product design was analyzed in this paper firstly. Aimed the shortages that the knowledge of the existing system for product design was close and the distributed knowledge couldn't be integrated and shared, a novel distributed knowledge management system framework for product design was proposed. The main layers were studied and the key(More)
In the convergence network which consists of cognitive self-organization network and mobile cellular network (MCN), the emergency service requires the network with higher reliability and quality of service (QoS). However, the time-variant factors such as spectrum, channel, network topology, node energy, as well as the gateway performance make the stochastic(More)
OBJECTIVE To study the distribution characteristics of lactobacillus in the vaginal mucosa of patients with HPV infection. METHODS The planting density of lactobacillus in vaginal secretions of 95 cases with HPV16/18 infection and 90 cases of normal women of childbearing age were observed by oil microscope. And the strains of vaginal lactobacilli in two(More)
OBJECTIVE To determine the effect of an interventional program designed to improve adherence to American Academy of Pediatrics (AAP) guidelines for palivizumab prophylaxis. METHODS The study was carried out at the Children's Hospital, University of California, Irvine Medical Center and its affiliated clinics. An interventional program focusing on(More)
The mathematical model of braking torque on eddy current retarder is analyzed. Aim at the shortages that comparing real output torque of eddy current retarder at high velocity the error of the mathematical model's computation torque is big, a braking torque model based on neural network model is proposed. The neural network model of eddy current retarder is(More)
It is shown that an event sample from the Monte Carlo simulation of a random cascading α model with fixed dynamical fluctuation strength is intermittent but not chaotic, while the variance of dynamical fluctuation strength in different events will result in both the intermittency and the chaoticity behavior. This shows that fractality and chaoticity are two(More)
