Our main challenge is the stability conditions for systems with gamma-distributed delays, where the delay is stabilizing, i.e. the corresponding system with the zero-delay as well as the system without the delayed term are not asymptotically stable.
The Riemann problem for a one-dimensional nonlinear wave system with different gamma laws is considered.

One-dimensional nonlinear wave system with the variable gamma laws which only depends on the spatial coordination is described as follows: begin{aligned} textstylebegin{cases} rho_{t}+(rho u)_{x}=0, (rho u)_{t}+p(rho,gamma)_{x}=0, gamma_{t}=0, end{cases}displaystyle end{aligned} (1.1) where p(rho,gamma)=Arho^{gamma(x)} (1.2) and (gamma(x)>1) and (A>0).
When we compared the resolution of our BSGI system with the standard gamma cameras at our institute, we found that the resolution of the BSGI system deteriorates faster with increasing distance, but for clinically relevant distances of up to 8 cm, these differences remained relatively small.

Following the preliminary human study, improvements were made to the measurement system with respect to the gamma-ray detector array and to the timing sequence of irradiation-transfer-counting.
The purpose of this study was to evaluate the feasibility of gamma camera system with CdWO4 detector for quantitation of Y-90 bremsstrahlung imaging using a Geant4 Application for Tomographic Emission (GATE).
Indeed in a recent study inspecting differences in long-range coupling between tinnitus patients and controls Schlee et al. [31] show altered activity in the central auditory system, with alterations in 'alpha and gamma networks' including frontal, parietal and cingulate brain areas for tinnitus patients.
