OBJECTIVE To describe the behavior of mortality in Mexico through four indicators from 1990 to 2012. MATERIAL AND METHODS The official mortality and population records of Mexico were used. RESULTS An advance was achieved for children under five years of age, with a decrease in mortality, although there was an increase in the years of potential life lost (YPLL) from 2008 for this age group. ...

Pulsar spindown forms a reliable yet enigmatic prototype for the energy loss processes in many astrophysical objects including accretion disks and back holes. In this paper we review the physics of pulsar magnetospheres, concentrating on recent developmen ts in force-free modeling of the magnetospheric structure. In particular, we discuss a new method for solving the equations of time-dependent...

Many life insurance companies are turning to technology to speed and remove cost from the underwriting process. Automated underwriting systems have been developed to reduce the manpower, time and/or data necessary to underwrite a life insurance application, while maintaining the quality of underwriting decisions. Although these systems have been in existence for some time, not much is known abo...

In order to apply asset-liabilitymanagement techniques to property-liability insurers, the sensitivity of liabilities to interest rate changes, or duration, must be calculated. The current approach is to use the Macaulay or modified duration calculations, both of which presume that the cash flows are invariant with respect to interest rate changes. Based on the structure of liabilities for prop...
