	Bipolar Disorder \| Bipolar Treatment \| Bipolar Medication » Bipolar Child
		Bipolar Disorder, also known as Manic Depressive Illness, causes dramatic changes in a person’s mood, energy, and ability to function. Most people experience moderate mood swings, this is normal, although more drastic changes in mood could be a symptom of Bipolar Disorder. 1-2% of the population suffers from bipolar disorder, about 4 million people.
		Bipolar disorder, also known as manic-depressive illness, is quite prevalent in USA and the numbers are on a rise with the stressors of life on a rise.
		Bipolar disorder is a mental illness in whish one faces unpredictable mood swings ranging from depressive symptoms to manic symptoms.

	Bipolar Disorder FAQ Part I - Overview to Bipolar
		Bipolar disorder, also known as manic depression, is a mood disorder characterized by extreme shifts in mood, from depressive lows to manic highs.
		What are the symptoms of bipolar I? Bipolar I requires only the presence of a single manic episode, though just about all people with bipolar I experience major depressive episodes, as well.
		bipolar depression has been little studied, as the depressive side of the equation until very recently was taken for granted by researchers and clinicians.

	Bipolar Disorder - Tempering the Mania of Manic Depression.
		Any discussion of the process of bipolar disorder and mania cannot be entirely divorced from a discussion of the depressive response.
		The basic premise of this exercise for tempering our bipolar disorder mania is that it is possible to utilize the energy of mania, anger, and despair towards a therapeutic end.
		At some time during an episode of bipolar disorder mania you will hit a wall, that point where all your efforts seem ill conceived and there is no hope that you will ever succeed in your efforts to overcome the depressive response or mania.

	IBM RD 50-1 \| Bipolar spintronics: Fundamentals and applications
		Analogous to bipolar charge transport [29, 30], which is dominated by the influence of the nonequilibrium carrier density, nonequilibrium spin density (unequal populations of “spin-up” and “spin-down” carriers) plays an important role in bipolar spintronics.
		Outside the depletion region, the system of drift-diffusion equations reduces to only diffusion equations for spin density and the density of minority carriers, while the density of majority carriers is simply given by the density of donors and acceptors [25, 86].
		Equation (37) generalizes the Silsbee–Johnson spin-charge coupling [109, 110], originally proposed for ferromagnet/paramagnet metal interfaces, to the case of magnetic p–n junctions.

		To be able to determine the diffusivity in vivo the diffusion process itself has to be monitored, i.e., the random motions of an ensemble of particles, rather than solving the equation for some initial and boundary conditions.
		Equation 3.4 shows that the diffusivity can be inferred directly by measuring the second moment of the conditional probability distribution of the diffusing species.
		This last equation relates the measured signal attenuation to the diffusivity, and is the basis for diffusion measurement using NMR.
