On the Uncertainty Identification for Linear Dynamic Systems Using Stochastic Embedding Approach with Gaussian Mixture Models.

In control and monitoring of manufacturing processes, it is key to understand model uncertainty in order to achieve the required levels of consistency, quality, and economy, among others. In aerospace applications, models need to be very precise and able to describe the entire dynamics of an aircraft. In addition, the complexity of modern real systems has turned deterministic models impractical, since they cannot adequately represent the behavior of disturbances in sensors and actuators, and tool and machine wear, to name a few.

[Factors influencing the choice of a career in primary care among medical students in Central America].

Objectives: To identify the preferred specialties, salary perception and other factors that influence the choice of a career in primary care among last-year medical students or social service students in Central America.

Methods: A cross-sectional, multicenter study using a survey that investigated demographic information, preferred specialty, salary perception, and other factors that influence the choice of a specialty.

Results: A total of 1 722 students from 31 universities participated and identified as future specialties: surgery (11.

A data augmentation approach for a class of statistical inference problems.

We present an algorithm for a class of statistical inference problems. The main idea is to reformulate the inference problem as an optimization procedure, based on the generation of surrogate (auxiliary) functions. This approach is motivated by the MM algorithm, combined with the systematic and iterative structure of the Expectation-Maximization algorithm.

H-NMR spin-lattice and correlation times of burned soft-tissue after treatment with an infrared pulsed laser device.

Background And Objectives: The aim of this study was to investigate the spin-lattice (T(1), 1/T(1)) and correlation times (tau(c)) of burned soft-tissue after treatment with an infrared (IR) pulsed laser device (IPLD, 904 nm pulsed at 3 MHz).

Study Design/materials And Methods: Seven groups (GI-GVII), each consisting of four albino rats, were used. Groups I-VI were anesthetized and burned with a hot tip: GI, GIII, GV were not irradiated; GII, GIV, GVI were irradiated at 0; 0 and 24; and 0, 24, and 48 hours, respectively.
