The circuit combines optical sensors and associated electronics o...

We describe several explicit examples of simple abelian surfaces over real quadratic fields with real multiplication and everywhere good reduction. These examples provide evidence for the Eichler–Shimura conjecture for Hilbert modular forms over a real quadratic field. Several of the examples also support a conjecture of Brumer and Kramer on abelian varieties associated to Siegel modular forms ...

The status of the resummation of small x contributions to the unpolarized and polarized deep inelastic structure functions is reviewed. Lecture notes to appear in the Proceedings of the Ringberg Workshop ”New Trends in HERA Physics 1999”, eds. G. Grindhammer, B. Kniehl, and G. Kramer (Springer, Berlin 1999).

Salen-type mononuclear lanthanide complexes with formula (Et3NH)[Ln(3-NO2-salen)2]·solvent (Ln = Eu (1Eu), Tb (2Tb), Dy (3Dy), Ho (4Ho), Er (5Er), Yb (6Yb); 3-NO2-salen(2-) = N,N'-bis(3-nitro-salicylaldehyde)ethylenediamine dianion) are reported. These compounds are isostructural in which two crystallographically distinct 3-NO2-salen(2-) act as tetradentate ligands encapsulating the lanthanide ...

When nurse researcher Marlene Kramer published Reality Shock: Why Nurses Leave Nursing in 1974, her seminal work launched a national discussion related to the distress felt by many baccalaureate-prepared novice nurses about leaving the academic setting and transitioning to the clinical setting. In particular, Kramer (1974) highlighted conflict between the values these new nurses had been taught...

Sibling relationship and personality characteristics of 87 pre-school sibling dyads were measured twice one year apart. Using the Inventory of Child Individual Differences (Halverson et al., 2003), mothers and fathers rated their children’s personality traits. Parent-perceived warmth, agonism, and rivalry/competition in sibling relationship were assessed by Parental Expectations and Perceptions...
