The Higgs as a Portal to Plasmon-like Unparticle Excitations
12 LaTeX pages, 2 figures.-- Published in: JHEP04(2008)028.-- Final full-text version available at: http://dx.doi.org/10.1088/1126-6708/2008/04/028.A renormalizable coupling between the Higgs and a scalar unparticle operator O_U of non-integer dimension d_U<2 triggers, after electroweak symmetry breaking, an infrared divergent vacuum expectation value for O_U. Such IR divergence should be tamed before any phenomenological implications of the Higgs-unparticle interplay can be drawn. In this paper we present a novel mechanism to cure that IR divergence through (scale-invariant) unparticle self-interactions, which has properties qualitatively different from the mechanism considered previously. Besides finding a mass gap in the unparticle continuum we also find an unparticle pole reminiscent of a plasmon resonance. Such unparticle features could be explored experimentally through their mixing with the Higgs boson.Work supported in part by the European Commission under the European Union through

Geistige ProduktivitÀt in Leben und Werk tiefenpsychologischer Forscher
Die Dissertation befasst sich mit dem bisher in der Forschung vernachlĂt aus tiefenpsychologischer Perspektive. Gemeint ist die ProduktivitĂt wird nicht in erster Linie als geniale Einzelleistung verstanden, sondern als Akkumulation vieler kleiner und groĂer Leistungen, als Zusammenarbeit vieler und als Erzeugnis eines langjĂt thematisieren.
Einem RĂckblick auf die Entwicklung des Begriffes ProduktivitĂischen Philosophiegeschichte folgt die Abgrenzung zu verwandten Begriffen wie KreativitĂt und andere geistige Prozesse der ProduktivitĂt.
Im Mittelpunkt stehen Leben und Werk von vier besonders produktiven Wissenschaftlern, Sigmund Freud, Alfred Adler, Otto Rank und Josef Rattner. In einem ersten Schritt wird in autobiografischem und biografischem Material dieser Autoren nach Charakteraspekten gesucht, die fĂr geistige ProduktivitĂhnen, wĂhigkeit, Skepsis, Offenheit fĂr GruppengesprĂt fĂr Bildungsgeschehen und PersĂnlichkeitsformung hervorzuheben sind.
In einem zweiten Schritt wird geprĂft, welche theoretischen Aussagen und Konstrukte der Autoren mit den aufgezeigten Charaktereigenschaften verwandt sind, sodass ein Gesamtbild entsteht, das die Lebensgeschichte mit der Theorie des jeweiligen Forschers verbindet.
Die vier Autoren stimmen in der Auffassung Ăberein, dass Intelligenz und Geistigkeit nicht rein rational sind, sondern tief im Emotionalen und Leiblichen verankert sind. Demnach entfaltet sich geistige ProduktivitĂt hemmen, sind neben materieller Not und Bildungsmangel die ausufernde Unterhaltungsindustrie und der zunehmende KonformitĂt nicht auf einen oder wenige Faktoren zurĂckzufĂhren ist, sondern als ein Strukturmodell, bestehend aus zahlreichen Elementen, verstanden werden muss. Dabei ist das Strukturmodell Diltheys hilfreich, da es verschiedene Einstellungen, Tugenden, Emotionen und CharakterzĂge in ihrem Zusammenhang und als Bedingung fĂr geistige ProduktivitĂsst. Es war allerdings nicht die Aufgabe dieser Dissertation, alle mĂglichen Elemente erschĂpfend dazustellen, sondern einen Weg aufzuzeigen, wie man sich dem PhĂt annĂ$hern kann.Mental productivity, up to now neglected in research, is seen as producing works of art, literature and science etc. In this dissertation it is not mainly understood as the ingenious product of a singular person, but as accumulation of many smaller and greater achievements, as a cooperation of many persons and as a result of a conjoint and continued thinking of groups. Mental productivity and neighbouring notions, such as creativity, labour and achievement are defined. The focus is directed on works of researchers in depth psychology, as they supply ample biographical material and discuss productivity in their writings.
The life and works of four remarcably productive researchers, Sigmund Freud, Alfred Adler, Otto Rank and Josef Rattner are discussed. In a first step characteristics of the four authors, relevant for productivity are identified. A second step establishes a relation between these characteristics and the theoretical writings of each of them.
The four authors agree that intelligence and spirituality have not only pure rational sources, but are deeply grounded in emotions and the physical human existence. It follows that mental productivity will only develop, when all aspects of a personality are activated, not only intellect and reason, but also feelings, interhuman exchange and a sense of values.
Finally it is stated that mental productivity cannot be reduced to only one or a few factors. It must be understood as a structural model, consisting of numerous elements. The philosopher Wilhelm Dilthey has developed a structure model, which helps demonstrating the influence of emotions, convictions, attitudes and characteristics upon mental productivity.
However, this dissertation was not intended to assemble all possible elements of productivity, but to demonstrate a means of approaching this phenomenon.Klaus HölzerAbweichender Titel laut Ăbersetzung der Verfasserin/des VerfassersKlagenfurt, Alpen-Adria-Univ., Diss., 2008KB2008 04OeBB(VLID)240953
Predictors of impaired SARS-CoV-2 immunity in healthcare workers after vaccination with BNT162b2
Healthcare workers are at substantially increased risk for infection with SARS-CoV-2. Successful vaccination constitutes a crucial prerequisite to protect this group during the pandemic. Since post vaccination antibody monitoring is not standard of care in all healthcare institutions, data on risk factors of impaired vaccine induced immune response are urgently required. Moreover, there are no data on cellular immune responses in humoral low responders so far. Anti-SARS-CoV-2 spike IgG was assessed after vaccination with BNT162b2 in 1386 employees of three hospitals of a German healthcare provider. Concentrations were compared to those of 45 convalescent employees. Vaccine-induced cellular immunity was measured in employees with reduced humoral response by assessment of frequencies of SARS-CoV-2-reactive and T cell. Anti-SARS-CoV-2 spike IgG were detected in 99.9% of 1386 healthcare workers after completed vaccination. The median antibody concentration was significantly higher after vaccination than after infection with SARS-CoV-2 (pâ=â0.0001). 10 subjects (0.7%) generated an IgG concentrationâ<â100 IU/ml, and only two persons (0.1%, solid organ recipients) did not produce detectable antibodies at all. T cell responses of those subjects with submaximal or lacking humoral response were comparable to employees with maximal antibody titers. 50% of those individuals with impaired or lacking humoral immune response were on immunosuppression. Vaccination to SARS-CoV-2 with BNT162b2 is very effective in healthcare workers yielding a seroconversion rate of 99.9%. Immunosuppression is the most important risk factor of an impaired immune response. There was no case of vaccination failure without immunosuppression. Thus, post vaccination antibody monitoring is highly recommendable in those employees with immunosuppression
