A large animal literature implicates serotonin (5-HT) in the modulation of positive and negative a€ective behavior. In contrast, data from human studies almost exclusively emphasize 5-HT modulation of negative emotional processing. However, no previous studies have directly assessed the relation between 5-HT functioning and positive (PA) and negative (NA) a€ect. The present investigation tested...

pain is one of the most important and sometimes difficult problems, that patients and physicians are encountered. it may be clinically acute or chronic, acute pain has usually definite cause and favourable response to treatment. on the other hand there are difficulties in diagnosis and management of chronic pain. peripheral and cranial nerves convey pain impulses toward central nervous system, ...

Modulation index estimation is important in the demodulation and recognition of Angle Modulation (AM) signals which include Frequency Modulation (FM) and Phase Modulation (PM) signals. In this paper, we firstly analyzed the AM signals with baseband modulation types, such as monotone, PSK, FSK, in the time and frequency domains. Then, we established a unified mathematical representation for the ...

In this paper, a 7-level Diode Clamped Multilevel Inverter (DCMLI) is simulated with three different carrier PWM techniques. Here, Carrier based Sinusoidal Pulse Width Modulation (SPWM), Third Harmonic Injected Pulse Width Modulation (THIPWM) and Modified Carrier-Based Space Vector Pulse Width Modulation (SVPWM) are used as modulation strategies. These modulation strategies include Phase Dispos...
