Lower-extremity resistance training on unstable surfaces improves proxies of muscle strength, power and balance in healthy older adults: a randomised control trial
Background: It is well documented that both balance and resistance training have the potential to mitigate intrinsic fall risk factors in older adults. However, knowledge about the effects of simultaneously executed balance and resistance training (i.e., resistance training conducted on unstable surfaces [URT]) on lower-extremity muscle strength, power and balance in older adults is insufficient. The objective of the present study was to compare the effects of machine-based stable resistance training (M-SRT) and ...
Untergangsphantasien/-diskurse: Goll, Céline, Gracq, Houellebecq
Aktuelle Themen wie das des lateinischen Reichs laden dazu ein, sie nach Maßgabe sachlicher, historisch-politischer Voraussetzungen zu diskutieren. Der vorliegende Beitrag versucht unter dem Stichwort Untergangsphantasien nichtsdestoweniger einen Schritt zurückzutreten und das diskursive, narrative Feld zu klären, in dem solche Diskussionen beheimatet sind.

Die vorliegende Arbeit befasst sich mit der betriebswirtschaftlichen Betrachtung und der systemtheoretischen Analyse der muttergebundenen Kälberaufzucht in der ökologischen Milchviehhaltung.
Zwischen RAF und Romantik
(Verlag Barbara Budrich, 2016)
Der 1973 erschienene Roman erzählt – ebenso wie das ein Jahr später in der Bearbeitung von Kurt Vethake produzierte Hörspiel – die Geschichte einer Erziehung zur Mündigkeit. Herr Taschenbier gehört zu jenen Menschen, die unterdrückt werden, weil sie sich unterdrücken lassen.
tRNA anticodon loop modifications ensure protein homeostasis and cell morphogenesis in yeast
Using budding yeast, we investigated a negative interaction network among genes for tRNA modifications previously implicated in anticodon-codon interaction: 5-methoxy-carbonyl-methyl-2-thio-uridine (mcm5s2U34: ELP3, URM1), pseudouridine (Ψ38/39: DEG1) and cyclic N6-threonyl-carbamoyl-adenosine (ct6A37: TCD1). In line with functional cross talk between these modifications, we find that combined removal of either ct6A37 or Ψ38/39 and mcm5U34 or s2U34 results in morphologically altered cells with synthetic growth defects. ...
Different forms of life satisfaction and their relation to affectivity
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. Case ...
High-precision force sensing using a single trapped ion
We introduce quantum sensing schemes for measuring very weak forces with a single trapped ion. They use the spin-motional coupling induced by the laser-ion interaction to transfer the relevant force information to the spin-degree of freedom. Therefore, the force estimation is carried out simply by observing the Ramsey-type oscillations of the ion spin states. Three quantum probes are considered, which are represented by systems obeying the Jaynes-Cummings, quantum Rabi (in 1D) and Jahn-Teller (in 2D) models. By using ...
No Evidence for Ionotropic Pheromone Transduction in the Hawkmoth Manduca sexta
Insect odorant receptors (ORs) are 7-transmembrane receptors with inverse membrane topology. They associate with the conserved ion channel Orco. As chaperon, Orco maintains ORs in cilia and, as pacemaker channel, Orco controls spontaneous activity in olfactory receptor neurons. Odorant binding to ORs opens OR-Orco receptor ion channel complexes in heterologous expression systems. It is unknown, whether this also occurs in vivo. As an alternative to this ionotropic transduction, experimental evidence is accumulating ...
Applying Least Absolute Shrinkage Selection Operator and Akaike Information Criterion Analysis to Find the Best Multiple Linear Regression Models between Climate Indices and Components of Cow’s Milk
This study focuses on multiple linear regression models relating six climate indices (temperature humidity THI, environmental stress ESI, equivalent temperature index ETI, heat load HLI, modified HLI (HLI new), and respiratory rate predictor RRP) with three main components of cow’s milk (yield, fat, and protein) for cows in Iran. The least absolute shrinkage selection operator (LASSO) and the Akaike information criterion (AIC) techniques are applied to select the best model for milk predictands with the smallest ...
Giving Is Nicer than Taking: Preschoolers Reciprocate Based on the Social Intentions of the Distributor
Recent research has found that even preschoolers give more resources to others who have previously given resources to them, but the psychological bases of this reciprocity are unknown. In our study, a puppet distributed resources between herself and a child by taking some from a pile in front of the child or else by giving some from a pile in front of herself. Although the resulting distributions were identical, three- and five-year-olds reciprocated less generously when the puppet had taken rather than given resources. ...
