Fast increased fidelity approximate Gibbs samplers for Bayesian Gaussian process regression [article]

Kelly R. Moran, Matthew W. Wheeler
2020 arXiv   pre-print
The use of Gaussian processes (GPs) is supported by efficient sampling algorithms, a rich methodological literature, and strong theoretical grounding. However, due to their prohibitive computation and storage demands, the use of exact GPs in Bayesian models is limited to problems containing at most several thousand observations. Sampling requires matrix operations that scale at O(n^3), where n is the number of unique inputs. Storage of individual matrices scales at O(n^2), and can quickly

To overcome these bottlenecks, we develop a sampling algorithm using H matrix approximation of the matrices comprising the GP posterior covariance. These matrices can approximate the true conditional covariance matrix within machine precision and allow for sampling algorithms that scale at O(n ^2 n) time and storage demands scaling at O(n n). We also describe how these algorithms can be used as building blocks to model higher dimensional surfaces at O(d n ^2 n), where d is the dimension of the surface under consideration, using tensor products of one-dimensional GPs. Though various scalable processes have been proposed for approximating Bayesian GP inference when n is large, to our knowledge, none of these methods show that the approximation's Kullback-Leibler divergence to the true posterior can be made arbitrarily small and may be no worse than the approximation provided by finite computer arithmetic. We describe H-matrices, give an efficient Gibbs sampler using these matrices for one-dimensional GPs, offer a proposed extension to higher dimensional surfaces, and investigate the performance of this fast increased fidelity approximate GP, FIFA-GP, using both simulated and real data sets.

Mesoporous organohydrogels from thermogelling photocrosslinkable nanoemulsions

Matthew E. Helgeson, Shannon E. Moran, Harry Z. An, Patrick S. Doyle
2012 Nature Materials  
We report the formation of mesoporous organohydrogels from oil-in-water nanoemulsions containing an end-functionalized oligomeric gelator in the aqueous phase. The nanoemulsions exhibit an abrupt thermoreversible transition from a low-viscosity liquid to a fractal-like colloidal gel of droplets with mesoscale porosity and solid-like viscoelasticity with moduli approaching 100 kPa, possibly the highest reported for an emulsion-based system. We hypothesize that gelation is brought about by

The use of photocrosslinkable gelators enables the freezing of the nanoemulsion's microstructure into a soft hydrogel nanocomposite containing a large fraction of dispersed liquid hydrophobic compartments, and we show its use in the encapsulation and release of lipophilic biomolecules. The tunable structural, mechanical and optical properties of these organohydrogels make them a robust material platform suitable for a wide range of applications.

Two-legged hopping in autism spectrum disorders

Matthew F. Moran, John T. Foley, Mary E. Parker, Michael J. Weiss
2013 Frontiers in Integrative Neuroscience  
Sensory processing deficits are common within autism spectrum disorders (ASD). Deficits have a heterogeneous dispersion across the spectrum and multimodal processing tasks are thought to magnify integration difficulties. Two-legged hopping in place in sync with an auditory cue (2.3, 3.0 Hz) was studied in a group of six individuals with expressive language impaired ASD (ELI-ASD) and an age-matched control group. Vertical ground reaction force data were collected and discrete Fourier transforms

The ELI-ASD group were unsuccessful in matching their hopping cadence (2.21 ± 0 1 .30 hops·s −1 , 2.35 ± 0.41 hops·s − ) to either auditory cue with greater deviations at the 3.0 Hz cue. In contrast, the control group was able to match hopping cadence (2 35 ± 0 06 hops·s −1 1 . . , 3.02 ± 0.10 hops·s − ) to either cue via an adjustment of effective leg stiffness. The ELI-ASD group demonstrated a varied response with an interquartile range (IQR) in excess of 0.5 hops 1 ·s −1 as compared to the control group with an IQR < 0.03 hops·s − . Several sensorimotor mechanisms could explain the inability of participants with ELI-ASD to modulate motor output to match an external auditory cue. These results suggest that a multimodal gross motor task can (1) discriminate performance among a group of individuals with severe autism, and (2) could be a useful quantitative tool for evaluating motor performance in individuals with ASD individuals.

Isolation of the Buchnera aphidicola flagellum basal body from the Buchnera membrane [article]

Matthew J Schepers, James N Yelland, Nancy A Moran, David W Taylor
2021 bioRxiv   pre-print
Buchnera aphidicola is an intracellular bacterial symbiont of aphids and maintains a small genome of only 600 kbps. Buchnera is thought to maintain only genes relevant to the symbiosis with its aphid host. Curiously, the Buchnera genome contains gene clusters coding for flagellum basal body structural proteins and for flagellum type III export machinery. These structures have been shown to be highly expressed and present in large numbers on Buchnera cells. No recognizable pathogenicity factors

Here, we show isolation of Buchnera flagella from the cellular membrane of Buchnera, confirming the enrichment of flagellum proteins relative to other proteins in the Buchnera proteome. This will facilitate studies of the structure and function of the Buchnera flagellum structure, and its role in this model symbiosis.

Collaboration personas

Tara Matthews, Steve Whittaker, Thomas Moran, Sandra Yuen
2011 Proceedings of the 2011 annual conference on Human factors in computing systems - CHI '11  
The success of social computing has generated a host of workplace collaboration tools. However, adoption of these tools by entire groups is a major problem. One reason for the adoption problem is a lack of methods for considering collaborative groups in technology design. Even when designing collaboration tools, designers often employ methods that focus on individuals. This leads to tools that are not well targeted at the groups who will use them. To solve this problem, we propose the notion of
more » ... collaboration personas, which are empirically derived descriptions of hypothetical groups, including details that inform the design of collaboration tools. Collaboration personas differ from individual personas in having (1) multiple, inter-related individuals playing specific roles; (2) a focus on collective goals and elaboration of individual goals that affect the collective goal; and (3) new attributes that characterize collaborative aspects of the group's work. We contrast collaboration personas with other design approaches and provide examples of how they can be used to design new collaborative tools that better meet the needs of typical groups.
