Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Bipolar Disorders

, 2014
Bipolar disorder is characterized by (hypo)manic episodes and depressive episodes which alternate with euthymic periods. It causes serious disability with poor outcome, increased suicidality risk, and significant societal costs. This chapter describes the findings of the PET/SPECT research efforts and the current ideas on the pathophysiology of bipolar

Epidemiology of Bipolar Disorders [PDF]

Epilepsia, 2005
Summary:  Bipolar, or manic–depressive, disorders are frequent and severe mental illnesses associated with considerable morbidity and mortality. Epilepsy and bipolar disorder could probably share some aspects of pathophysiology because manic as well as depressive symptoms are seen in patients with seizures, and a number of antiepileptic drugs are ...

Predominant polarity as a potential moderator of group CBT outcomes in bipolar disorder: an exploratory post-hoc analysis

Frontiers in Psychiatry
IntroductionBipolar disorder (BD) is a chronic and severe mood disorder, characterized by recurrent episodes of mania, hypomania, and depression. Adjacent to pharmacotherapy, positive evidence has been found for the benefit of adding cognitive behavioral

Differences between Depression Episodes of Bipolar Disorder I and II [PDF]

Psikiyatride Güncel Yaklaşımlar, 2013
In 1975 Fieve and Dunner made the distinction between hypomania and mania as hypomania does not usually cause social and occupational impair-ment and hospitalization is not needed, moreover patients do not experience psychosis. Bipolar disorder type I is

Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

Advanced Materials, EarlyView.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.
