The combination of radioanalytical methods and ultrasensitive Accelerator Mass Spectrometry (AMS) allows the determination of long-lived cosmogenic radionuclides in the environment, which can be used to quantify geological processes. In the first part of the studies presented here, the radiochemical investigation of quartz rich samples from the interior of the Wohlthat-Massiv, Queen Maud Land, Antarctica is presented. [...]

Analyse der Dynamik zellulärer Calcium Signale mit spezifisch lokalisierten Sensorproteinen
[Juel-4369]
Berichte des Forschungszentrums Jülich 4369, XI, 125 p. (2014)
Calcium (Ca$^{2+}$) is an essential second messenger that regulates and modulates a variety of cellular functions. In particular, local changes of the calcium concentration play a key role in physiologically relevant processes. [...]

Stimulus relevance modulates contrast adaptation in visual cortex
eLife 6, e21589 (2017) [10.7554/eLife.21589]  GO
A general principle of sensory processing is that neurons adapt to sustained stimuli by reducing their response over time. Most of our knowledge on adaptation in single cells is based on experiments in anesthetized animals. [...]

Trigeminale Innervation des olfaktorischen Systems: Anatomie undFunktion
[Juel-4372]
Berichte des Forschungszentrums Jülich 4372, XI, 140 p. (2014)
Das olfaktorische System dient der Wahrnehmung von Gerüchen und somit vor allem der Erkennung von Nahrungs- oder Gefahrenquellen. Dem trigeminalen System werden in erster Linie somatosensorische Eigenschaften zugeschrieben. [...]

Structural prediction of the interaction of the tumor suppressor p27$^{KIP1}$ with cyclin A/CDK2 identifies a novel catalytically relevant determinant
BackgroundThe cyclin-dependent kinase 2 (CDK2) together with its cyclin E and A partners is a central regulator of cell growth and division. Deregulation of CDK2 activity is associated with diseases such as cancer. [...]

Young adolescents with autism show abnormal joint attention network: A gaze contingent fMRI study
Behavioral research has revealed deficits in the development of joint attention (JA) as one of the earliest signs of autism. While the neural basis of JA has been studied predominantly in adults, we recently demonstrated a protracted development of the brain networks supporting JA in typically developing children and adolescents.

Spin anisotropy due to spin-orbit coupling in optimally hole-doped Ba $_{0.67}$ K $_{0.33}$ Fe $_{2}$ As $_{2}$
We use polarized inelastic neutron scattering to study the temperature and energy dependence of spin space anisotropies in the optimally-hole-doped iron pnictide Ba0.67K0.33Fe2As2 (Tc=38 K). In the superconducting state, while the high-energy part of the magnetic spectrum is nearly isotropic, the low-energy part displays a pronounced anisotropy, manifested by a c-axis polarized resonance.

SANS study of vortex lattice structural transition in optimally doped (Ba $_{1− x}$ K $_{x}$ )Fe $_{2}$ As $_{2}$
Small-angle neutron scattering on high quality single crystalline Ba1−x K x Fe2As2 reveals the transition from a low-field vortex solid phase with orientational order to a vortex polycrystal at high magnetic field. The vortex order–disorder transition is correlated with the second-peak feature in isothermal hysteresis loops, and is interpreted in terms of the generation of supplementary vortex solid dislocations.
