Three-dimensional architecture and biogenesis of membrane structures associated with hepatitis C virus replication
All positive strand RNA viruses are known to replicate their genomes in close association with intracellular membranes. In case of the hepatitis C virus (HCV), a member of the family Flaviviridae, infected cells contain accumulations of vesicles forming a membranous web (MW) that is thought to be the site of viral RNA replication. However, little is known about the biogenesis and three-dimensional structure of the MW. In this study we used a combination of immunofluorescence- and electron microscopy (EM)-based methods to analyze the membranous structures induced by HCV in infected cells. We found that the MW is derived primarily from the endoplasmic reticulum (ER) and contains markers of rough ER as well as markers of early and late endosomes, COP vesicles, mitochondria and lipid droplets (LDs). The main constituents of the MW are single and double membrane vesicles (DMVs). The latter predominate and the kinetic of their appearance correlates with kinetics of viral RNA replication. DMVs are induced primarily by NS5A whereas NS4B induces single membrane vesicles arguing that MW formation requires the concerted action of several HCV replicase proteins. Three-dimensional reconstructions identify DMVs as protrusions from the ER membrane into the cytosol, frequently connected to the ER membrane via a neck-like structure. In addition, late in infection multi-membrane vesicles become evident, presumably as a result of a stress-induced reaction. Thus, the morphology of the membranous rearrangements induced in HCV-infected cells resemble those of the unrelated picorna-, corona- and arteriviruses, but are clearly distinct from those of the closely related flaviviruses. These results reveal unexpected similarities between HCV and distantly related positive-strand RNA viruses presumably reflecting similarities in cellular pathways exploited by these viruses to establish their membranous replication factories
Reservoir Computing Approach to Robust Computation using Unreliable Nanoscale Networks
As we approach the physical limits of CMOS technology, advances in materials
science and nanotechnology are making available a variety of unconventional
computing substrates that can potentially replace top-down-designed
silicon-based computing devices. Inherent stochasticity in the fabrication
process and nanometer scale of these substrates inevitably lead to design
variations, defects, faults, and noise in the resulting devices. A key
challenge is how to harness such devices to perform robust computation. We
propose reservoir computing as a solution. In reservoir computing, computation
takes place by translating the dynamics of an excited medium, called a
reservoir, into a desired output. This approach eliminates the need for
external control and redundancy, and the programming is done using a
closed-form regression problem on the output, which also allows concurrent
programming using a single device. Using a theoretical model, we show that both
regular and irregular reservoirs are intrinsically robust to structural noise
as they perform computation

Development and testing of gene expression biomarkers for gonadal dysgenesis in conjunction with the US EPA endocrine disruptor screening program's Tier 2 larval amphibian growth and development assay
University of Minnesota M.S. thesis. April 2014. Major: Toxicology. Advisors: Dr. Sigmund J. Degitz, Dr. Patrick Schoff, Dr. Kendall Wallace. 1 computer file (PDF); vii, 105 pages, appendices A-B.The Endocrine Disrupter Screening Program of US EPA has recently developed a Tier 2 testing guideline using model amphibian species Xenopus laevis. The Larval Amphibian Growth and Development Assay assesses a chemical's endocrine-related effects in vivo and generates concentration-response information for ecological risk-assessment. Currently, the assay relies on histopathological evaluations for identifying endocrine-related reproductive effects. However, histopathology can seldom define the chemical mode of action and is not easily interpreted in the context of risk assessment when the effects are minimal to moderate. This study explores the use of gene expression biomarkers in the gonad that could potentially inform a chemical's mode of action and detect adverse reproductive effects that are otherwise uncharacterized by histopathology. To identify candidate biomarkers, global expression was analyzed in differentiating ovary and testis tissues of Xenopus tropicalis. Genetic programs responsible for reproductive maturation in gonad tissues were characterized and provided a foundation from which specific genes could be selected proximal to a model chemical's known mode of action. Four genes were selected within the putative androgen molecular network to evaluate as biomarkers of the anti-androgen mode of action characteristic of a common fungicide, prochloraz. Following continuous exposure to prochloraz throughout embryonic, larval and juvenile development in Xenopus laevis, assessments of growth, liver and kidney pathology, and reproductive development were made. To evaluate the predictive capabilities of the candidate genes, one gonad was kept in situ for histopathological evaluations while the other was processed for mRNA analyses. Results indicate that prochloraz exposure caused metabolic toxicity in the liver and kidney; it caused testis degeneration coincident with the onset of androgen-mediated spermatogenesis and inhibited regression of Müllerian ducts. Two of the four candidate genes showed increases in expression at the high test concentration and appeared to be predictive of an anti-androgen-induced adaptive response. The behavior of these biomarkers stimulated valuable discussion and generated testable hypotheses to better understand the evolution of molecular mechanisms driving gonad development in a cross-species context. This study provides a model for expression-based biomarker development in endocrine tissues and offers direction toward enhanced ecological risk-assessment
Time of flight measurements based on FPGA using a breast dedicated PET
In this work the implementation of a Time-to-Digital Converter (TDC) using a Nutt
delay line FPGA-based and applied on a Positron Emission Tomography (PET) device is going
to be presented in order to check the system’s suitability for Time of Flight (TOF) measurements.
In recent years, FPGAs have shown great advantages for precise time measurements in PET. The
architecture employed for these measurements is described in detail. The system developed was
tested on a dedicated breast PET prototype, composed of LYSO crystals and Positive Sensitive
Photomultipliers (PSPMTs). Two distinct experiments were carried out for this purpose. In the
first test, system linearity was evaluated in order to calibrate the time measurements, providing a
linearity error of less than 2% and an average time resolution of 1.4 ns FWHM. The second set
of measurements tested system resolution, resulting in a FWHM as good as 1.35 ns. The results
suggest that the coincidence window for the current PET can be reduced in order to minimize the
random events and thus, achieve better image qualityAguilar, A.; García Olcina, R.; Martos, J.; Soret, J.; Torres-Pais, J.; Benlloch Baviera, JM.; González Martínez, AJ.... (2014).

Evolutionary rates vary among rRNA structural elements
Understanding patterns of rRNA evolution is critical for a number of fields, including structure prediction and phylogeny. The standard model of RNA evolution is that compensatory mutations in stems make up the bulk of the changes between homologous sequences, while unpaired regions are relatively homogeneous. We show that considerable heterogeneity exists in the relative rates of evolution of different secondary structure categories (stems, loops, bulges, etc.) within the rRNA, and that in eukaryotes, loops actually evolve much faster than stems. Both rates of evolution and abundance of different structural categories vary with distance from functionally important parts of the ribosome such as the tRNA path and the peptidyl transferase center. For example, fast-evolving residues are mainly found at the surface; stems are enriched at the subunit interface, and junctions near the peptidyl transferase center. However, different secondary structure categories evolve at different rates even when these effects are accounted for. The results demonstrate that relative rates and patterns of evolution are lineage specific, suggesting that phylogenetically and structurally specific models will improve evolutionary and structural predictions
A Reconfigurable Fabric for Accelerating Large-Scale Datacenter Services
Datacenter workloads demand high computational capabilities, flexibility, power efficiency, and low cost. It is challenging to improve all of these factors simultaneously. To advance datacenter capabilities beyond what commodity server designs can provide, we designed and built a composable, reconfigurable hardware fabric based on field programmable gate arrays (FPGA). Each server in the fabric contains one FPGA, and all FPGAs within a 48-server rack are interconnected over a low-latency, high-bandwidth network. We describe a medium-scale deployment of this fabric on a bed of 1632 servers, and measure its effectiveness in accelerating the ranking component of the Bing web search engine. We describe the requirements and architecture of the system, detail the critical engineering challenges and solutions needed to make the system robust in the presence of failures, and measure the performance, power, and resilience of the system. Under high load, the large-scale reconfigurable fabric improves the ranking throughput of each server by 95% at a desirable latency distribution or reduces tail latency by 29% at a fixed throughput. In other words, the reconfigurable fabric enables the same throughput using only half the number of servers
