Which characteristic is commonly associated with treatment-resistant depression?

Cognitive symptoms in schizophrenia, such as poor working memory and executive dysfunction, are thought to be related to dysregulation in which neurotransmitter system?

In the depressive phase of bipolar disorder, which neurotransmitter dysregulation is most likely contributing to symptoms of fatigue, lack of motivation, and anhedonia?

Match the aspect of HPA axis dysregulation with its impact on depressive symptoms.

15 Points A 10.0 kg block is released from point A as shown in the Diagram.  The track is frictionless except for the portion between points B and C, which has a length of 6.0 meters and a coefficient of friction μK = 0.36.  The block travels down the track and hits a spring with k = 2250 N/m What is the speed at point B? How much work is done by friction from point B and C? What is the speed of the block at point C? How much does the spring compress in bringing the block to rest?  

Which of the following is a common side effect of lithium that requires regular monitoring?

Match each mechanism of action to the expected clinical effect in the patient.

15 Points A 0.1 kg block is released from rest at point A (See diagram), a vertical distance h above the ground.  It slides down an inclined track, around a circular loop of radius 0.5 meters, then up another incline that forms an angle of 30° with the horizontal.  The block slides off the track at a speed of 4.0 m/s at point C, which is at a height of 0.5 meters above the ground.  (Assume the entire track is frictionless) Determine the height of the initial position of the block. Determine the Normal Force acting on the Block at the top of the Loop Determine the Horizontal Distance that the block will land from the edge of the ramp at point C

In a study, participants were asked to evaluate two contradictory theories. If they preferred one theory and subsequently favored evidence that supported it while dismissing evidence against it, this is an example of: 

What is the greatest number of unique keys a perfect B+ Tree with n=3, l=40 and height=2 (has levels 0, 1, 2) can have (Assume unique values are inserted)? Assume 0 based height. A tree with a single root node has a height = 0. n = maximum children a node can have l = maximum keys a leaf node can have
