The goal of this article is to review the progress of three-electron spin qubits from their inception to the state of the art. We direct the main focus towards the exchange-only qubit (Bacon et al 2000 Phys. Rev. Lett. 85 1758–61, DiVincenzo et al 2000 Nature 408 339) and its derived versions, e.g. the resonant exchange (RX) qubit, but we also discuss other qubit implementations using three ele...

The focus of our effort has been to develop quantum information processing technologies based on a solid-state cavity QED platform consisting of quantum dots in photonic crystals. The main goals that we have accomplished include: 1. Study of the ultrafast dynamics of the quantum dot-cavity QED system [Majumdar et al., Phys. Rev. A, 2012], and ultrafast switching between two single photon pulses...

genesis of pancreatic b-cells in humans has been documented in a number of physiological processes, such as pregnancy (Butler et al., 2010), injury (Berrocal et al., 2005) and in response to increased metabolic demand (Saisho et al., 2012). The ability to exploit the intrinsic capacity of the adult pancreas to produce new b-cells would provide exciting new treatment modalities for individuals s...

Paks4, along with Paks5, and 6 are members of the group B family of p21-activated kinases (Paks). The Paks play multiple different roles in controlling cell morphology, cell growth, proliferation, and signaling. Pak4 has essential roles in embryonic development (Qu et al., 2003), but in adults high levels of Pak4 are frequently associated with cancer. Pak4 has been implicated in several types o...

Global loss of 85% of oyster reef ecosystems over the past 130 yr (Beck et al. 2011) has led to both growing recognition of the services once provided by healthy oyster reef ecosystems (Grabowski et al. 2012) and increasing interest in restoring these ecosystems. In Chesapeake Bay, USA, populations of the native oyster Crassostrea virginica have been reduced to <1% of historic levels through a ...

World population growth and food demand have been two major elements leading to the expansion of animal and fish production. Recently, many efforts advocated the extension of intensive fish farming to optimize the need for animal protein (Hussein et al., 2013). In Korea, aquaculture has made rapid development in a short period of time, and many fish farms have been established in order to fulfi...
