koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Locally-owned convenience stores and the local economy
No full textThe convenience store sector in the UK has been growing strongly in recent years. Anecdotal commentary and media coverage claims that locally-owned stores are more advantageous for community coherence and resilience, being embedded socially and economically more strongly (than chain stores) in their local community. This paper extends our understanding of this. Following a review of the literature on social and economic aspects of convenience store operation, a multi-stage mainly qualitative research process was undertaken. Using four case stores in Scotland, this research demonstrates the local engagement of locally owned convenience stores and points to a stronger awareness and detail of the economic rather than the social aspects of this engagement. Differences with corporately owned convenience stores are identified. In policy terms the research shows that more work needs to be done to identify, quantify and then promote the advantages of local ownership of stores

Engineered magnetoconductance in InAs nanowire quantum dots
No full textMagnetoconductance is the change in the electrical transport properties of a solid state system in response to an applied magnetic field, determined by both its magnitude and orientation. Such effects arise in many shapes and forms, depending on how the magnetic field couples to the charge carriers and thus affect the conductance.
In this thesis, we investigate various aspects of magnetoconductance arising in quantum dots defined in semiconducting InAs nanowires. Quantum dots - nanostructures which confine charge carriers in all three spatial dimensions – are a well-controlled system for the study and manipulation of single electron spins. InAs nanowires provide a versatile platform for such devices, well-suited to examine different aspects of magnetoconductance. This is due to the relative ease of achieving Ohmic contacts and the strong coupling of the electron spins to magnetic fields, as formulated in a large g factor. Furthermore, the presence of strong spin–orbit interaction carries the possibility of controlling electron spins and magnetoconductance using electric fields.
The direct coupling of the spins and the external magnetic field is addressed by examining the g factor in InAs nanowire quantum dots. The orientation dependence of the g factor is mapped out using two methods for an InAs nanowire quantum dot, revealing considerable anisotropy of similar magnitude for the two studied charge states, between of bulk-like values of 15 and quenched down to 5. However, no correlation was found between the anisotropy axes and the symmetries of the device, nor the charge states.
Nanowire-based quantum dot spin-valve devices were also studied, which offer a straightforward approach to investigate the spin physics in solid state systems through spin-polarized currents. In such devices, the magnetic field affects the conductance through the magnetization of the ferromagnetic leads, making high-quality contacts essential. Our discussion focuses on the fabrication aspects of the novel approach of quasi-suspended ferromagnetic contacts developed for nanowire devices.
The main focus of the thesis is the in-depth investigation of the combined effect of local electric and magnetic fields for devices with ferromagnetic split-gate geometries. This approach utilizes the locally strong magnetic stray fields of ferromagnetic side gate pairs near a semiconducting InAs nanowire. These nanomagnetic structures consist of two long ferromagnetic strips, whose magnetization is reversed at a characteristic external magnetic field, the coercive field. These ferromagnetic side-gates have a controlled and spatially confined magnetic field and can also be used as local electrical gates.
We present proof-of-principle magnetoconductance experiments, in which we find state-dependent and hysteretic features. The conductance depends on both the external and the local magnetic field of the side gates. For most resonances, a sharp change is encountered in the magnetoconductance at the 35 mT coercive field of the nanomagnets, consistent with a stray field offset of about 50 mT. These features are strongly state-dependent and gate tunable with relative changes up to ±50% at the coercive field. More intriguingly, we also find more complex features, reminiscent of tunneling magnetoresistance (TMR) between two ferromagnets, though our device is not in direct contact with a ferromagnet.
We account for most magnetoconductance features using intuitive single- and double-dot models, which qualitatively reproduce our experimental findings. Our model shows that the TMR-like characteristics could stem from a transition between singlet and triplet ground state of a double quantum dot.
The approach of ferromagnetic side gates also opens an avenue for conceptually new experiments: for entanglement detection exploiting non-collinear spin projection axes in the two branches of a Cooper pair splitter, or the creation of fractional fermions by inducing a spatially periodic magnetic field using a superstructure of such nanomagnets

Leading Locally: How New Zealand's mayors get things done
No full textNew Zealand’s directly elected mayors are considered an example of a weak mayoral model, with mayors having limited legal powers to make decisions or appointments. However, many mayors continue to shape policy direction alongside their councillor colleagues. This article examines how a collaborative leadership approach allows mayors to successfully lead locally even without strong executive powers. Future reforms of local government should consider how to build on this leadership framework
What Can Be Computed Locally?
No full textAbstract. The purpose of this paper is a study of computation that can be done locally in a distributed network, where "locally " means within time (or distance) independent of the size of the network. Locally Checkable Labeling (LCL) problems are considered, where the legality of a labeling can be checked locally (e.g., coloring). The results include the following: ffl There are non-trivial LCL problems that have local algorithms. ffl There is a variant of the dining philosophers problem that can be solved locally. ffl Randomization cannot make an LCL problem local; i.e., if a problem has a local randomized algorithm then it has a local deterministic algorithm. ffl It is undecidable, in general, whether a given LCL has a local algorithm. ffl However, it is decidable whether a given LCL has an algorithm that operates in a given time t. ffl Any LCL problem that has a local algorithm has one that is order-invariant (the algorith
