Three-dimensional solutions of the magnetohydrostatic equations : rigidly rotating magnetized coronae in spherical geometry
No full textContext. Magnetohydrostatic (MHS) equilibria are often used to model astrophysical plasmas, for example, planetary magnetospheres or coronae of magnetized stars. However, finding realistic three-dimensional solutions to the MHS equations is difficult, with only a few known analytical solutions and even finding numerical solution is far from easy. Aims. We extend the results of a previous paper on three-dimensional solutions of the MHS equations around rigidly rotating massive cylinders to the much more realistic case of rigidly rotating massive spheres. An obvious application is to model the closed field line regions of the coronae of rapidly rotating stars. Methods. We used a number of simplifying assumptions to reduce the MHS equations to a single elliptic partial differential equation for a pseudo-potential U, from which all physical quantities, such as the magnetic field, the plasma pressure, and the density, can be derived by differentiation. The most important assumptions made are stationarity in the co-rotating frame of reference, a particular form for the current density, and neglect of outflows. Results. In this paper we demonstrate that standard methods can be used to find numerical solutions to the fundamental equation of the theory. We present three simple different cases of magnetic field boundary conditions on the surface of the central sphere, corresponding to an aligned dipole field, a non-aligned dipole field, and a displaced dipole field. Our results show that it should be possible in the future to use this method without dramatically increasing the demands on computational resources to improve upon potential field models of rotating magnetospheres and coronae.Peer reviewe
The development and validation of the modern homonegativity scale (MHS)
No full textThis thesis details the psychometric properties of the Modern Homonegativity Scale (MHS), which is designed to measure negative attitudes toward gay men and lesbians. Four studies assessed: 1) the values perceived to be violated and upheld by gay men and lesbians (N=40), 2) the reliability and factor structure of a preliminary version of the MHS (N=353), 3) the reliability and construct validity of the final version of the MHS (N=309), and 4) a behavioural expression of modern homonegativity (N=36). The MHS is unidimensional and possesses a high degree of internal consistency. As hypothesized, MHS scores correlated positively with political conservatism, religious behaviour and self-schema, modern sexism, and endorsement of the Protestant Work Ethic, and correlated negatively with acceptance of an Humanitarian-Egalitarian ideology. MHS scores were not contaminated by social desirability bias. An experimental examination of the construct validity of modern homonegativity revealed that high-scoring participants on the MHS were less likely to sit beside individuals wearing t-shirts with pro-gay/pro-lesbian slogans. The present studies reveal that modem homonegativity exists and operates within university populations.The original print copy of this thesis may be available here: http://wizard.unbc.ca/record=b119166
Farley Lavette—MHS Overview References
No full textThis video is a recording of a meeting on Managed Healthcare System (MHS). The speaker lectures on the organization of MHS, MHS’ electronic system, the process that MHS uses to determine eligibility for coverage, the terminology of MHS, and different file types in MHS. The speaker explains how MHS easily sorts grouped information by specific classifications. The speaker also shows how programs work in the system by writing them out. He discusses a database for claims information and the formatting for provider profiles as well.https://digitalcommons.unf.edu/flblue_media/1056/thumbnail.jp
INTEROPERABILITY ISSUES WITH MHS GENESIS
No full textThe MHS GENESIS electronic health record software purchased by the Defense Health Agency is not interoperable with the healthcare managed organizations network of care. Twenty percent of all specialty care health records are not returned to the medical treatment facility. This represents a significant loss of health records, a potential loss in medical readiness, as well as the ability to deploy. The purpose of this study was to demonstrate if the market-comparable electronic health record retrieved health records better than MHS GENESIS. The hypothesis H1: MyChart electronic health record is more interoperable, making it more accurate than the MHS GENESIS electronic health record. H2: Changes to the Defense Health Agency’s health record policy will make MHS GENESIS more interoperable. The research design was a mixed-method approach. The comparative analysis of interoperability between MyChart software and MHS GENESIS software used nominal, ordinal, and interval-based methods to calculate results. The research design used for the qualitative analysis section was based on the Qualtrics XM software’s word cloud. MHS GENESIS is capable of interoperating with HMO providers, but it is limited by DHA’s health record policy. The survey revealed beneficiaries are concerned with the accuracy and accessibility of a complete interoperable system. Due to limited technical knowledge of MyChart and MHS GENESIS, we recommend study of MHS GENESIS within the large MTF multi-market regions.Approved for public release.

Samtrafikk mellom MHS og teletex
No full textSammendrag av et foredrag avholdt på UNINETT-prosjektets MHS-seminar 22. og 23. januar 1985. Den Internasjonale Televerkskomitéen (CCITT) har utarbeidet en modell for MHS (Message handling systems). En del av modellen beskriver samtrafikk mellom MHS og apparater tilknyttet Teletex-tjenesten. Rapporten gir en kort beskrivelse av den kommunikasjons-modell og -protokoll som her benyttes
On the particle content of MHS theory
No full textThe Moyal-Higher-Spin (MHS) formalism, involving fields dependent on spacetime and auxiliary coordinates, is an approach to studying higher spin (HS)-like models. To determine the particle content of the MHS model of the Yang-Mills type, we calculate the quartic Casimir operator for on-shell MHS fields, finding it generally non-vanishing, indicative of infinite/continuous-spin degrees of freedom. We propose an on-shell basis for these infinite/continuous-spin states. Additionally, we analyse the content of a massive MHS model.32 page
