Mounting method improves electrical and vibrational characteristics of screen electrodes

Electrical characteristics of the mesh or screen electrodes used in electron tubes are improved by decreasing the shunt capacitance of the tube while retaining the close spacing needed for the required resolution. Vibrational characteristics are enhanced by raising the natural resonant frequency

Territorial Sovereignty and the Evolving Boumediene Factors: Al Maqaleh v. Gates and the Future of Detainee Habeas Corpus Rights

[Excerpt] “In November 2010, the U.S. government prosecuted in a civilian federal court an accused terrorist detainee housed since 2004 at the Guantanamo Bay Detention Center (Guantanamo Bay). The Obama Administration considered this trial a “test case” for prosecuting accused terrorist detainees in civilian federal courts. Of the more than 280 charges against the detainee defendant, a civilian jury convicted him of one count and acquitted him of the remaining charges. Yet, the defendant received a life sentence without parole. This “test case” is one example of a changing landscape in international armed conflict and detainee rights jurisprudence following September 11, 2001. This Note discusses one area of American constitutional law that has clearly evolved in recent detainee rights litigation: the extraterritorial reach of the Suspension Clause and extension of habeas corpus rights to detainees held beyond U.S. sovereign territory. Historically, territorial sovereignty determined the extraterritorial reach of the Suspension Clause. In 2008, however, Boumediene v. Bush greatly impacted the role of territorial sovereignty in extraterritorial habeas jurisprudence. In Boumediene, the Supreme Court developed a practical, multi-factor test for determining the reach of the Suspension Clause while holding that federal courts were not foreclosed from entertaining habeas petitions from Guantanamo Bay detainees. This was the first decision to allow detainee foreign nationals held beyond U.S. sovereign territory to seek habeas corpus relief through the federal courts. Now that Guantanamo Bay has been addressed, recently, the focus has shifted to detainees held at the Bagram Theater Internment Facility (Bagram) in Afghanistan. In May 2010, the D.C. Circuit in Al Maqaleh v. Gates held that the balance of Boumediene’s multi-factor test weighed against extending the Suspension Clause to four detainees captured beyond Afghanistan and detained at Bagram as unlawful enemy combatants. By analyzing the development of the Boumediene multifactor test and focusing on its application to the Bagram detainees, this Note proposes that territorial sovereignty is no longer a controlling or driving factor in today’s extraterritorial habeas analysis. Furthermore, this Note provides a few practical recommendations for future applications of the Boumediene multi-factor test and addresses some unanswered questions in applying the test in future detainee cases. Part II provides a brief history of the extraterritorial habeas jurisprudence relating to foreign national detainees leading up to Al Maqaleh. Part III discusses the Al Maqaleh decisions in both the district court and the court of appeals. Part IV analyzes the declining role that territorial sovereignty plays in today’s habeas analysis. Part IV also discusses various unanswered questions that await decision by the Supreme Court in applying the Boumediene test in future detainee cases.

Fonned and Refonned: What God Effects through the Liturgical Assembly of Christians

(Excerpt) It is a privilege to be invited to offer a keynote address to the Institute of Liturgical Studies, where so much serious reflection and energy for the renewal and study of Christian worship has been generated. As will become clear to you almost immediately, keynote today does not mean key in the sense of offering the key concept that is needed to unlock all subsequent deliberation on the important topic of forming Christians. In my case, key refers more frankly and realistically to the indispensable need to start somewhere by opening the door to subsequent work in the institute-with its speakers, its group sessions and workshops, and its liturgies. In a real sense what is needed at this year\u27s institute is not so much a key but a whole ring of keys. We who gather build on the two previous years\u27 work on worship, culture, and catholicity. Having explored the tensions between worship and culture in 1997, and the eschatological dimensions of those relationships in 1998, the institute this year turns to a moment of advocacy for the indispensable task of forming Christians

Transformed and Transforming: What God Effects through the Presence of Christians in the World

(Excerpt) On the model of mystagogy: remember your experience last night at the vigil, please, and recall these words from the eucharistic prayer: God and Father of our Lord Jesus Christ, open our eyes to see your hand at work in the world about us. Deliver us from the presumption of coming to this table for solace only and not for strength; for pardon only and not for renewal. Let the grace of this Holy Communion make us one body, one spirit in Christ that we may worthily serve the world in his name.\u27 And from Welcome to Christ: Dear Christian friends: Baptized into the priesthood of Christ, we are all called by the Holy Spirit to offer ourselves to the Lord of all creation in thanksgiving for all that God has done and continues to do fur us. It is our privilege to affirm those who are endeavoring to carry out their vocation as Christians in the world.

Kaon photoproduction on the nucleon with constrained parameters

The new experimental data of kaon photoproduction on the nucleon, gamma p -> K+ Lambda, have been analyzed by means of a multipoles model. Different from the previous models, in this analysis the resonance decay widths are constrained to the values given by the Particle Data Group (PDG). The result indicates that constraining these parameters to the PDG values could dramatically change the conclusion of the important resonances in this reaction found in the previous studies.Comment: 4 pages, 3 figures, talk given by Ryky Nelson at Fourth Asia-Pacific Conference on Few-Body Problems in Physics 2008 (APFB08), Depok, Indonesia, August 19-23, 200

Structure and dynamics of topological defects in a glassy liquid on a negatively curved manifold

We study the low-temperature regime of an atomic liquid on the hyperbolic plane by means of molecular dynamics simulation and we compare the results to a continuum theory of defects in a negatively curved hexagonal background. In agreement with the theory and previous results on positively curved (spherical) surfaces, we find that the atomic configurations consist of isolated defect structures, dubbed "grain boundary scars", that form around an irreducible density of curvature-induced disclinations in an otherwise hexagonal background. We investigate the structure and the dynamics of these grain boundary scars
