Electrical behaviour and evolutionary computation in thin films of bovine brain microtubules.

ABSTRACT: We report on the electrical behaviour of thin films of bovine brain microtubules (MTs). For samples in both their dried and hydrated states, the measured currents reveal a power law dependence on the applied DC voltage. We attribute this to the injection of space-charge from the metallic electrode(s). The MTs are thought to form a complex electrical network, which can be manipulated with an applied voltage. This feature has been exploited to undertake some experiments on the use of the MT mesh as a medium for computation. We show that it is possible to evolve MT films into binary classifiers following an evolution in materio approach. The accuracy of the system is, on average, similar to that of early carbon nanotube classifiers developed using the same methodology.

Project description:One common research goal in systems neurosciences is to understand how the functional relationship between a pair of regions of interest (ROIs) evolves over time. Examining neural connectivity in this way is well-suited for the study of developmental processes, learning, and even in recovery or treatment designs in response to injury. For most fMRI based studies, the strength of the functional relationship between two ROIs is defined as the correlation between the average signal representing each region. The drawback to this approach is that much information is lost due to averaging heterogeneous voxels, and therefore, the functional relationship between a ROI-pair that evolve at a spatial scale much finer than the ROIs remain undetected. To address this shortcoming, we introduce a novel evolutionary computation (EC) based voxel-level procedure to examine functional plasticity between an investigator defined ROI-pair by simultaneously using subject-specific BOLD-fMRI data collected from two sessions seperated by finite duration of time. This data-driven procedure detects a sub-region composed of spatially connected voxels from each ROI (a so-called sub-regional-pair) such that the pair shows a significant gain/loss of functional relationship strength across the two time points. The procedure is recursive and iteratively finds all statistically significant sub-regional-pairs within the ROIs. Using this approach, we examine functional plasticity between the default mode network (DMN) and the executive control network (ECN) during recovery from traumatic brain injury (TBI); the study includes 14 TBI and 12 healthy control subjects. We demonstrate that the EC based procedure is able to detect functional plasticity where a traditional averaging based approach fails. The subject-specific plasticity estimates obtained using the EC-procedure are highly consistent across multiple runs. Group-level analyses using these plasticity estimates showed an increase in the strength of functional relationship between DMN and ECN for TBI subjects, which is consistent with prior findings in the TBI-literature. The EC-approach also allowed us to separate sub-regional-pairs contributing to positive and negative plasticity; the detected sub-regional-pairs significantly overlap across runs thus highlighting the reliability of the EC-approach. These sub-regional-pairs may be useful in performing nuanced analyses of brain-behavior relationships during recovery from TBI.

Project description:Silicon heterojunction (SHJ) solar cells, as one of the most promising passivated contact solar cell technologies of the next generation, have the advantages of high conversion efficiency, high open-circuit voltage, low-temperature coefficient, and no potential-induced degradation. For the single-side rear-emitter SHJ solar cells, the n-type carrier selective layer, which serves as the light-incident side, plays a pivotal role in determining the performance of heterojunction devices. Consequently, a superior n-doped layer should exhibit high optical transmittance and minimal optical absorption, along with a substantial effective doping level to guarantee the formation of dark conductivity (σd) and electron-transport capacity. In this work, we investigated the optical and electrical properties of different n-type monolayers and stacked gradient multilayers, including monolayer, bilayer, and trilayer Si-based thin films, acting as electron-transport layers (ETL) prepared by plasma-enhanced chemical vapor deposition, and studied the influences of these above layers on the performance of SHJ solar cells. The experimental results demonstrate that the ETL with an n-nc-Si:H/n-nc-SiOx:H/n+-nc-Si:H trilayer structure exhibits the potential to boost highly efficient solar cells. The bottom highly crystallized, lightly phosphorus-doped n-nc-Si:H film promotes rapid nucleation of the intermediate n-nc-SiOx:H film and thus reduces the thickness of the incubation layer, as well as improves the passivation contact. The n-nc-SiOx:H film in the middle layer provides excellent optical properties and reduces parasitic absorption, thereby increasing the short-circuit current density. Furthermore, the highly doped n+-nc-Si:H at the top offers an optimal ohmic contact with the reactive plasma deposition-grown TCO layer, which ultimately enhances the fill factor. Ultimately, a conversion efficiency of 20.41%, with an open-circuit voltage of 720 mV, a short-circuit current density of 39.34 mA/cm2, and a filling factor of 72.05%, was achieved in the SHJ solar cell using a typical trilayer structure. This kind of trilayer structure has a particular significance for potential industrialized applications as it allows for efficient utilization of solar energy.
