Spatio-temporal representation of the pitch of complex tones in the auditory nerve and cochlear nucleus
… mapping in the cochlea, or on a purely temporal representation dependent on neural phase locking to the stimulus period. However, rate-place cues to the pitch of harmonic complex tones in the auditory nerve (AN) saturate at high levels, and temporal cues fail to predict the strong pitch …

Dispersive neural networks for adaptive signal processing
… signal production, channel equalization, and spatio-temporal pattern recognition. For comparison with conventional techniques, a dispersive network was trained to predict future values of a chaotic signal using only its present value as an input. With adaptable delays, the network had less …

Stochastic effects on extinction and pattern formation in the three-species cyclic May–Leonard model
… calculation. In addition, we study the spatio-temporal pattern formation of the stochastic May--Leonard model through the Doi-Peliti coherent state path integral formalism to obtain a coarse-grained Langevin description, i.e. the Complex Ginzburg Landau equation with stochastic noise in …

Cognitive and brain markers in presymptomatic genetic behavioural variant frontotemporal dementia: a case-control study
… genetic variant for behavioural variant frontotemporal dementia (bvFTD-MAPT), who are part of the FTDGeNZ study, with the aim of identifying early behavioural, cognitive and neural changes in gene-positive family members. Study one aimed to characterise signs of neuropsychological and …

A comprehensive study of the 26th December 2004 Sumatra earthquake: possible implications on Earth rotation and investigations on the coseismic and postseismic stress diffusion associated with the seismic rupture
… about two years and finally analyzed the spatio-temporal pattern. The analysis performed with the semi-analytical and the finite-element modeling gives a complex picture of the stress diffusion, in the area under study, after the Sumatra earthquake. We believe that the results obtained …

Coincidence detection in the cochlear nucleus : implications for the coding of pitch
The spatio-temporal pattern in the auditory nerve (AN), i.e. the temporal pattern of AN fiber activity across the tonotopic axis, provides cues to important features in sounds such as pitch, loudness, and spatial location. These spatio-temporal cues may be extracted by central neurons in the …

Spatial Ecology of Entomopathogenic Nematodes with Contrasting Foraging Strategies
… (EPNs) but little is known about their dispersal patterns in the field. Overall goal of this dissertation research was to examine the dispersal behavior of two EPN species with contrasting foraging strategies, cruiser, <i>Heterorhabditis</i> <i>bacteriophora</i> and ambusher, <i>Steinernema</i> …

Molecular imaging of spatio-temporal distribution of angiogenesis in hindlimb ischemia model and diabetic milieu
In the current thesis, spatio-temporal evaluation of the endogenous angiogenic response to ischemia was perfomed. After vascular occlusion, ischemic angiogenesis is an important reparative mechanism and can ameliorate the outcome of ischemic disease. Diabetic foot ulcers affect almost 15% of …

Die raum-zeitliche Variation von Microcystis spp. (Cyanophyceae) und Microcystinen in der Talsperre Quitzdorf (Sachsen)
Cyanobakterien bilden zahlreiche bioaktive Substanzen mit zum Teil humantoxischer Relevanz. Nicht selten spielen dabei zyklische Peptide, zu denen unter anderem die Microcystine (MCYST) gehören, eine Schlüsselrolle. MCYST werden u.a. von Microcystis KÜTZING EX LEMMERMANN 1907 gebildet. Erkenntnisse …
