Introduction: Radiation effects observed in cells that are not irradiated are known as non-targeted effects.  Radiation induced bystander effect (RIBE) as a kind of non-targeted effect has been introduced in recent  years.  RIBE  occurs  in  unexposed  cells  which  are  related  to  adjacent  or  distant  irradiated  cells.  RIBE  contradict with "target theory" which necessitates radiation tr...

Despite providing robustness, high-gain observers impose a peaking phenomenon, which may cause instability, on the system states. In this paper, an adaptive saturation is proposed to attenuate the undesirable mentioned phenomenon in high-gain observers. A real-valued and differentiable sigmoid function is considered as the saturating element whose parameters (height and slope) are adaptively tu...

trauma and stressor related disorders include disorders in which exposure to a traumatic or stressful event is listed explicitly as a diagnostic criterion. these include reactive attachment disorder, posttraumatic stress disorder (ptsd), acute stress disorder, and adjustment disorders. psychological distress following exposure to a traumatic or stressful event is quite variable. in some cases, ...

oro-antral communication and fistula can occur as a result of inadequate and improper treatment. inadvertent communication with the maxillary sinus can occur during certain surgical procedures in the maxillary posterior region. though, spontaneous healing may occur in defects which are smaller than 2 mm but larger communications require immediate attention and should be treated without delay, i...

Power system blackouts have become a serious problem for electric utilities especially in recent years. Different forms of system instability have emerged in recent blackouts, such as voltage instability and frequency instability. To counteract each form of system instability, special algorithms have been designed in the protection system, e.g. Under Frequency Load Shedding (UFLS) and Under Vol...
