Different forms of life satisfaction and their relation to affectivity
(2016-05-03)
Aims: The present study is aimed at studying the research question whether high satisfaction levels achieved through either (1) the fact that one's quality of life is truly satisfactory (i.e., stabilized life satisfaction) or through (2) adapting a more favorable perception of one's quality of life by lowering standards (i.e., resigned life satisfaction) are associated with different levels of positive affect (PA) and negative affect (NA) when compared to each other but also when compared to dissatisfied individuals.

Morphological and Genetic Diversity of Sea Buckthorn (Hippophae rhamnoides L.) in the Karakoram Mountains of Northern Pakistan
(2018-07-30)
Sea buckthorn (Hippophae rhamnoides L.) is a dioecious, wind-pollinated shrub growing in Eurasia including the Karakoram Mountains of Pakistan (Gilgit-Baltistan territory). Contrary to the situation in other countries, in Pakistan this species is heavily underutilized. Moreover, a striking diversity of berry colors and shapes in Pakistan raises the question: which varieties might be more suitable for different national and international markets? Therefore, both morphological and genetic diversity of sea buckthorn ...

Preferential weakening of rotational magnetic anisotropy by keV-He ion bombardment in polycrystalline exchange bias layer systems
(2018-05-04)
The consequences of keV light-ion bombardment of polycrystalline exchange bias layer systems on individual magnetic anisotropies composing the effective unidirectional magnetic anisotropy are investigated by vectorial magneto-optic Kerr effect measurements. Preferential reduction of rotatable magnetic anisotropy as compared to the other magnetic anisotropies is observable, disproving the intuitive assumption of an equable weakening of all magnetic anisotropies due to the bombardment. It is concluded that light-ion ...

Estimation of Vegetable Crop Parameter by Multi-temporal UAV-Borne Images
(2018-05-22)
3D point cloud analysis of imagery collected by unmanned aerial vehicles (UAV) has been shown to be a valuable tool for estimation of crop phenotypic traits, such as plant height, in several species. Spatial information about these phenotypic traits can be used to derive information about other important crop characteristics, like fresh biomass yield, which could not be derived directly from the point clouds. Previous approaches have often only considered single date measurements using a single point cloud derived ...

Expression of NK cluster genes in the onychophoran Euperipatoides rowelli: implications for the evolution of NK family genes in nephrozoans
(2018-07-18)
Background:
Understanding the evolution and development of morphological traits of the last common bilaterian ancestor is a major goal of the evo-devo discipline. The reconstruction of this “urbilaterian” is mainly based on comparative studies of common molecular patterning mechanisms in recent model organisms. The NK homeobox genes are key players in many of these molecular pathways, including processes regulating mesoderm, heart and neural development. Shared features seen in the expression patterns of NK genes ...

Roots of symptom-free leguminous cover crop and living mulch species harbor diverse Fusarium communities that show highly variable aggressiveness on pea (Pisum sativum)
(2018-02-14)
Leguminous cover crop and living mulch species show not only great potential for providing multiple beneficial services to agro-ecosystems, but may also present pathological risks for other crops in rotations through shared pathogens, especially those of the genus Fusarium. Disease severity on roots of subterranean clover, white clover, winter and summer vetch grown as cover crop and living mulch species across five European sites as well as the frequency, distribution and aggressiveness to pea of Fusarium spp. ...

Optimal control theory for a unitary operation under dissipative evolution
(2014)
We show that optimizing a quantum gate for an open quantum system requires the time evolution of only three states irrespective of the dimension of Hilbert space. This represents a significant reduction in computational resources compared to the complete basis of Liouville space that is commonly believed necessary for this task. The reduction is based on two observations: the target is not a general dynamical map but a unitary operation; and the time evolution of two properly chosen states is sufficient to distinguish ...

Familienpolitik - Die Entstehung der Dynastie
(2017)
Wer die Samuelbücher liest, wird vielleicht verwundert sein, wie groß der Stellenwert jener Geschichten rund um Heirat, Geburt, aber auch Ehebruch und sexualisierte Gewalt ist. Nur ein zweiter Textbereich der Hebräischen Bibel, die Erzelternerzählungen der Genesis (12-50), enthalten ähnlich viele Familienerzählungen. Während man jahrzehntelang in der historisch-kritischen Forschung etwas hilflos vor diesen Familienthemen stand und sie oft als Ablenkung von der eigentlich wichtigen Erzählung der großen Geschichte ...

Discours, textes, traditions
(2016)
Ce qui sert de base et de cadre au présent volume, résultat d’une sectiondes journées des romanistes de langue allemande (Romanistentag) à Berlin, a fait l’objet de recherches intenses et de bien des controverses ces dernières années ; il s’agit de la fonction des traditions discursives, qui, en tant que savoir culturel et linguistique, nous apprennent à concevoir des textes et qui sont le pivot d’une analyse textuelle linguistique orientée vers la culture.

Visuelle und verbale Konzeptualisierungen von Trauer in einer Umbruchsituation: Allan Ramsay skizziert sein totes Kind
(2015)
The British painter Allan Ramsay’s physiognomic sketch of his first son, deceased at the age of 14 months in 1741, can provide some insight into the shift of emotional response towards death during the eighteenth century. Although never used for the execution of an autonomous painting according to available visual conventions, Ramsay directed the attention of his conversation partners to the image, apparently in an attempt to claim a stoic firmness of character for himself modelled on prototypes found in the tradition ...
