The New Narrow "D_s" States -- A Minireview

The experimental status concerning the two new narrow states with charm-strange content is reviewed. The states have masses of 2317 and 2460 MeV, widths less than 10 MeV, isospin consistent with zero, and spin-parities consistent with being 0^+ and 1^+, respectively. Although the masses are lower than the conventional expectation, these states appear to be the j=1/2 P-wave levels of the D_s system, where j is the light quark angular momentum; there may be mixing with the j=3/2 level for the 1^+ state.Comment: 4 pages, 10 figures LaTeX; To appear in Proceedings of the International Europhysics Conference on High Energy Physics, July 17-23, 2003, Aachen.

The Witness of the Worshiping Community

(Excerpt) Christ is risen! Alleluia! CR: He is risen indeed! Alleluia!) What more does the church have to do than to proclaim this? What else must the church witness to than the resurrection of the crucified One, who is present in its midst through the preaching of the gospel and the administration of the sacraments? Oh, yes, we have to spin out the meaning of the cross and resurrection of Christ; we have to celebrate it worthily and compellingly in our public assemblies; we have to reorder our lives In conformity with its implications, turning away from the way of the world and toward the new life under Christ\u27s reign; we have to invite others to reorder their lives according to this new reality for the world; and we want to invite them to join us in a community of proclamation and celebration

Implementing Rapid Prototyping Using CNC Machining (CNC-RP) Through a CAD/CAM Interface

This paper presents the methodology and implementation of a rapid machining system using a CAD/CAM interface. Rapid Prototyping using CNC Machining (CNC-RP) is a method that has been developed which enables automatic generation of process plans for a machined component. The challenge with CNC-RP is not the technical problems of material removal, but with all of the required setup, fixture and toolpath planning, which has previously required a skilled machinist. Through the use of advanced geometric algorithms, we have implemented an interface with a CAD/CAM system that allows true automatic NC code generation directly from a CAD model with no human interaction; a capability necessary for a practical rapid prototyping system.Mechanical Engineerin

The Constitution on the Sacred Liturgy and Lutheran Book of Worship: What Was Renewed?

(Excerpt) Missing first four pages of the 1970s there were those who objected to the idea of liturgy as action because they thought it placed an undue emphasis on human activity instead of on God\u27s work through the means of grace.4 Obviously, liturgy is a work performed by a person or a community, so human action is unavoidable. It is a human act to read scriptures, preach sermons, baptize, or proclaim the words of institution, even though we confess that the Holy Spirit works through these means of grace to create or awaken faith. One may also say that liturgy, like all the activities of the church, is inspired or engendered by the Holy Spirit. For this reason the chief service has been called \u27\u27the divine liturgy (e.g. the Divine Liturgy of St. John Chrysostom)

The BCS critical temperature in a weak external electric field via a linear two-body operator

We study the critical temperature of a superconductive material in a weak external electric potential via a linear approximation of the BCS functional. We reproduce a similar result as in [Frank, Hainzl, Seiringer, Solovej, 2016] using the strategy introduced in [Frank, Hainzl, Langmann, 2018], where we considered the case of an external constant magnetic field.Comment: Dedicated to Herbert Spohn on the occasion of his seventieth birthday; 29 page

The BCS Critical Temperature in a Weak External Electric Field via a Linear Two-Body Operator

We study the critical temperature of a superconductive material in a weak external electric potential via a linear approximation of the BCS functional. We reproduce a similar result as in Frank et al. (Commun Math Phys 342(1):189–216, 2016, [5]) using the strategy introduced in Frank et al. (The BCS critical temperature in a weak homogeneous magnetic field, [2]), where we considered the case of an external constant magnetic field
