AbstractMixture density networks (MDNs) can be used to generate posterior density functions of model parameters $$\varvec{\theta }$$ θ given a set of observables $${\mathbf {x}}$$ x . In some applications, training data are available only for discrete values of a continuous parameter $$\varvec{\theta }$$ θ . In such situations, a number of performance-limiting issues arise which can result in biased estimates. We demonstrate the usage of MDNs for parameter estimation, discuss the origins of the biases, and propose a corrective method for each issue.

Objetivo: Determinar las actitudes y expectativas respecto a la maternidad o paternidad del estudiante de medicina de una universidad pública de Tacna. Material y métodos: Estudio descriptivo en 253 estudiantes del 1.º al 6.º año de la Escuela de Medicina Humana de la Universidad Nacional Jorge Basadre Grohmann de Tacna. Semilleros del 6.º año aplicaron encuesta anónima de opción múltiple, con consentimiento informado, en noviembre de 2018, con mentoría del docente del curso de Pediatría III. El procesamiento y análisis de datos se realizó con el programa SPSS v.23. Resultados: El 49.2 % de las mujeres sería madre de los 30 a 35 años; el 47.1 % tendría 2 hijos. De los varones, el 41.5 % sería padre de los 30 a 35 años; el 50 % tendría 2 hijos, y el 53.4 % le gustaría que el primer hijo fuera niño. Respecto al trabajo; el 76.1 % de las mujeres no tomarían doble horario para el sustento de su familia, y el 62 % contrataría una empleada; pero el 52.1 % de los varones sí tomaría doble horario de trabajo. No confían en cunas y jardines: un 67.6 % de mujeres y un 68.5 % de varones. Respecto a actitudes frente al matrimonio; el 62 % de mujeres y 67 % de varones se casaría por civil e iglesia, y solo el 18 % de mujeres y 16 % de varones no se casaría. Además; el 62 % de mujeres no se ligaría las trompas, y el 71 % considera que el ser “ama de casa” es igual de satisfactorio que trabajar por un sueldo; el 32 % de los varones no se haría la vasectomía, y el 74 % no usaría el castigo físico como método correctivo para sus hijos. Conclusión: Los estudiantes de medicina de la Universidad Nacional Jorge Basadre Grohmann pospondrían la maternidad o paternidad a edades superiores a 30 años, y limitaría el tamaño de su familia. Ambos sexos aún mantienen ideas conservadoras respecto al matrimonio, y las mujeres conservan la idea de ser amas de casa, además de su profesión. Results: 49.2 % of women, would be a mother at 30 to 35 ear old, 47.1 % would have 2 children. Of the men, 41.5 % would be a father at 30 to 35 year old, 50 % would have 2 children and 53.4 % would like the first child to be a boy. Regarding work, 76.1 % of women would not take double shifts at work to support their family and 62 % would hire an employee; but 52.1 % of the men would take double shifts at works. 67.6 % of women and 68.5 % of men do not trust cribs and gardens. Regarding attitudes towards marriage, 62 % of women and 67 % of men would marry by civil and church and only 18 % of women and 16 % of men would not marry. In addition, 62 % of women would not have their tubes tied and 71 % consider that being a homemaker is just as satisfying as working for a salary; 32 % of the men would not have a vasectomy and 74 % would not use physical punishment as a corrective method for their children.

Data transmitted from one location to the other has to be transferred reliably. Usually, error control coding algorithm provides the means to protect data from errors. Unfortunately, in many cases the physical link can not guarantee that all bits will be transferred without errors. It is then the responsibility of the error control algorithm to detect those errors and in some cases correct them so that upper layers will receive error free data. The polynomial code, also known as Cyclic Redundancy Code (CRC) is a very powerful and easily implemented technique to obtain data reliability. As data transfer rates and the amount of data stored increase, the need for simple and robust error detection codes should increase as well. Thus, it is important to be sure that the CRCs in use are as effective as possible. Unfortunately, standardized CRC polynomials such as the CRC-32 polynomial used in the Ethernet network standard are known to be grossly suboptimal for important applications, (Koopman, 2002). This research investigates the effectiveness of error detection methods in data transmission used several years ago when we had to do with small amount of data transfer and data storages compared with the huge amount of data we deal with nowadays.  A demonstration of erroneous bits in data frames that may not be detected by the CRC method will be shown. A corrective method to detect errors when dealing with humongous data transmission will also be given.
