Bipolar cascade lasers
… issues of the design and modeling of the Bipolar Cascade Laser (BCL), a new type of quantum well laser. BCLs consist of multiple single stage lasers electrically coupled via tunnel junctions. The BCL ideally operates by having each injected electron participate in a recombination event in …

Risk taking in bipolar disorder
Part 1Background: People with a diagnosis of bipolar disorder can make suboptimal decisions during manic and depressive episodes which can have negative long-term consequences. This review aims to explore individual factors, including mood state and personality traits, which could affect decision …

Reward-oriented processes in bipolar disorder
… characteristic reward-oriented processes in bipolar disorder and dysregulation in the behavioural activation system (BAS). This study aimed to assess differences between bipolar and healthy control individuals in their response to reward, failure and a reasoning task sensitive to …

Understanding the diagnostic process of Bipolar Disorder: A qualitative study of bipolar patients in Cape Town, South Africa
Bipolar Disorder (BD) is a complex psychiatric disorder posing many diagnostic challenges. Recent international research has highlighted a concerning rise in the number of patients diagnosed worldwide with BD each year. Although many studies have been conducted over the past two decades that aimed …

Risk taking behaviour in bipolar affective disorder
… of risk taking behaviour and impulsivity in bipolar affective disorder. Involvement in pleasurable activities that have a high potential, or risk, for unwanted consequences forms one of the DSM IV diagnostic criteria for (hypo)mania; however, little research has investigated the prevalence of …

CMOS/Bipolar current conveyor design and development
The aim of this research programme was to design and develop a novel CMOS current conveyor, to improve areas such as bandwidth, slew rate, gain, and Powe- Supply Reject Ratio (PSRR). The current conveyor can be used in low frequency applications such as LED drivers for mobile phones and …

Epidemiological Assessment of Bipolar Disorder in Canada
… of this thesis was to estimate the prevalence of bipolar disorder (BD) including bipolar I (BDI) and bipolar II (BDII) disorder subtypes, in Canada in 2012 and to characterize persons with BD in terms of demographic features, health status, and mental health service utilization. During the course …

Compound Semiconductor Power Heterojunction Bipolar Transistor Technology
This work will conclude by discussing the lingering issues with the GaN project and the methods in which to solve these issues. It will also discuss the implications of the power amplifier analysis.
-
Modeling and Characterization of Heterojunction Bipolar Transistors
Heterojunction bipolar transistor (HBTs) offer several advantages over their homo-junction counterparts resulting from the use of semiconductors in the emitter and base with different bandgaps. These advantages include high current gain, large cut-off frequency and short gate delay in digital logic …

Elucidating the genetic aetiology of Bipolar Disorder
Introduction: Bipolar disorder (BD) is a debilitating mood disorder with substantial genetic contributions. However, while the existence of its heritability is well-established, the precise genetic components and mechanisms of BD remain unknown. This is a pilot study aimed at optimising the use of …

Towards an evolutionary perspective of bipolar disorders: Is there a genetic link between bipolar disorders and non-pathological (adaptive) hyperactivity?
… recognized in the literature as associated with bipolar disorders, was found in well-adapted older adults without bipolar disorders and high hyperactivity traits with a similar frequency as in older adults with a diagnosis of bipolar disorders but higher than in older adults without bipolar …

Managing bipolar moods without medication : a qualitative investigation
… family interventions for people diagnosed with Bipolar Disorder (BD) lead to better outcomes for their relatives, who often exhibit greater service utilisation and greater distress than the general population. Following a systematic search of the quantitative literature, ten papers were …
