Do Sojourn Effects on Personality Trait Changes Last? A Five‐Year Longitudinal Study

open access: yesEuropean Journal of Personality, EarlyView., 2020
Abstract This study examined sojourners' long‐term personality trait changes over five years, extending previous research on immediate sojourn effects. A sample of German students (N = 1095) was surveyed thrice (T1–T3) over the course of an academic year.

The impact of dose rate on the accuracy of step-and-shoot intensity-modulated radiation therapy quality assurance using varian 2300CD

open access: yesJournal of Medical Physics, 2017
Introduction: Intensity-modulated radiation therapy (IMRT) delivery using “step-and-shoot” technique on Varian C-Series linear accelerator (linac) is influenced by the communication frequency between the multileaf collimator and linac controllers. Hence,

Location-dependent excitatory synaptic interactions in pyramidal neuron dendrites. [PDF]

open access: yesPLoS Computational Biology, 2012
Neocortical pyramidal neurons (PNs) receive thousands of excitatory synaptic contacts on their basal dendrites. Some act as classical driver inputs while others are thought to modulate PN responses based on sensory or behavioral context, but the ...

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism

open access: yesAdvanced Science, EarlyView.
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

Non-cyanobacterial diazotrophs support the survival of marine microalgae in nitrogen-depleted environment

open access: yesGenome Biology
Background Non-cyanobacteria diazotrophs (NCDs) are shown to dominate in surface waters shifting the long-held paradigm of cyanobacteria dominance. This raises fundamental questions on how these putative heterotrophic bacteria thrive in sunlit oceans ...

A Thirty‐Year Gap: Reviving All‐Nitride Glasses as Processable, High‐Performance Materials

open access: yesAdvanced Science, EarlyView.
Oxygen‐free all‐nitride glasses are revisited in light of new avenues of synthesis, raw material availability, and applications. A semi‐empirical analysis predicts mechanical performance achieving the level of engineering ceramics while maintaining visual transparency, and significant potential regarding optical properties into the infrared spectral ...

Human Ring Chromosomes – New Insights for their Clinical Significance

open access: yesBalkan Journal of Medical Genetics, 2013
Twenty-nine as yet unreported ring chromosomes were characterized in detail by cytogenetic and molecular techniques. For FISH (fluorescence in situ hybridization) previously published high resolution approaches such as multicolor banding (MCB ...
