Improving Data Availability in Cloud Storage with Efficient Replication (2012)

Data availability is one of the keyrequirements for cloud storage system. Datareplication has been widely used as a mean ofincreasing the availability in traditional distributeddatabases, peer-to-peer (P2P) systems, and gridsystems. These strategies were all developed forspecific platforms and application types and havebeen tailored to the characteristics of the underlyingsystem architectures and application requirements.Cloud systems differ from these previous frameworksin that they are designed to support large numbers ofcustomer-oriented applications, each with differentquality of service (QoS) requirements and resourceconsumption characteristics. Aiming to provide highdata availability, and improve performance and loadbalancing of cloud storage, efficient replicationmanagement scheme is proposed. In replicationmanagement, the system provides optimum replicanumber as well as weighting and balancing amongthe storage server nodes and experimental resultsprove that the proposed system can improve dataavailability depending on the expected availabilityand failure probability of each node in PC cluster.
Designed Self‐Assembled β‐Sheet Peptide Fibrils as Templates for Silica Nanotubes (2004)

Abstract Sol–gel condensation of tetraethoxysilane in the presence of designed self‐assembled β‐sheet peptide fibril templates, followed by template extraction, yields hollow silica nanotubes. The nanotubes are hundreds of nanometers long and possess a central pore of ∼ 3.5 nm, determined by the fibril template diameter. The effects of synthesis conditions have been investigated and the resultant silica materials characterized by various techniques. Silica nanostructures with various morphologies have been produced previously using supramolecular organic assemblies as templates. Hollow nano‐ or microtubes, which may have applications in separations, catalysis, nano‐optics, and ‐electronics have been of particular interest. Peptide‐based templates are especially interesting because of their relevance to biological silica microstructure formation. The new fibrillar peptide templates described here have the advantages of prescribed diameter, twist pitch, and handedness, which should impart chirality on the resulting silica nanotubes, providing control of the internal surface architecture by appropriate peptide design.

Impacts of vaccination and Severe Acute Respiratory Syndrome Coronavirus 2 variants Alpha and Delta on Coronavirus Disease 2019 transmission dynamics in four metropolitan areas of the United States (2021)

Using a compartmental model parameterized to reproduce available reports of new Coronavirus Disease 2019 (COVID-19) cases, we quantified the impacts of vaccination and Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) variants Alpha (lineage B.1.1.7) and Delta (lineage B.1.617.2) on regional epidemics in the metropolitan statistical areas (MSAs) surrounding Dallas, Houston, New York City, and Phoenix.
Nitrogen-Doped Hierarchical Porous Biochar Derived from Corn Stalks for Phenol-Enhanced Adsorption (2019)

Nitrogen-doped hierarchical porous biochar has aroused great interest in energy storage and adsorption applications. In this study, nitrogen-doped hierarchical porous biochar was prepared from corn stalks by in situ pyrolysis with urea as the nitrogen source and NaHCO3 as the green activation agent. The liquid adsorption behavior of biochar was evaluated using phenol as a pollutant probe. The results showed that urea had a synergistic effect on the pore structure development of biochar in the presence of an activation agent. The addition of urea especially promoted the formation of micropores. X-ray photoelectron spectroscopy results showed that nitrogen atoms were successfully introduced into the skeleton of biochar in the form of different nitrogen species, which promote the adsorption of phenol. The phenol adsorption was dominated by micropore filling, and the adsorption capacity was positively correlated with the content of graphitic N. The nitrogen-doped biochar obtained at 700 °C with a moderate surface area and a high content of graphite type N exhibited the highest adsorption capacity of phenol. The kinetic analysis also indicates the existence of chemical interactions in the adsorption process.

Low-Complexity User Selection for Rate Maximization in MIMO Broadcast Channels with Downlink Beamforming (2014)

We present in this work a low-complexity algorithm to solve the sum rate maximization problem in multiuser MIMO broadcast channels with downlink beamforming. Our approach decouples the user selection problem from the resource allocation problem and its main goal is to create a set of quasiorthogonal users. The proposed algorithm exploits physical metrics of the wireless channels that can be easily computed in such a way that a null space projection power can be approximated efficiently. Based on the derived metrics we present a mathematical model that describes the dynamics of the user selection process which renders the user selection problem into an integer linear program. Numerical results show that our approach is highly efficient to form groups of quasiorthogonal users when compared to previously proposed algorithms in the literature. Our user selection algorithm achieves a large portion of the optimum user selection sum rate (90%) for a moderate number of active users.
Structural Response of Bovine Growth Hormone to Dead-Ended Ultrafiltration (2003)

Bovine growth hormone (bGH) was used as a model pharmaceutical protein to assess protein structural stability during dynamic ultrafiltration. Two popular membrane materials of different wettabilities, poly(ether sulfone) (PES) and regenerated cellulose (RC), are exposed to acidic and basic bGH solutions in a dead-ended filtration. After a three-fold concentration run, samples of the feed, permeate, and retentate are subjected to a series of spectroscopic and physical analytical techniques, permitting quantitative characterization of the secondary and tertiary structure of bGH as well as the aggregation state of the bGH in these streams. At pH 4, where the monomeric form predominates in the feed, bGH loses helix and gains sheet content as it passes through the membranes. At pH 9, where the feed contains mainly dimers, bGH in the permeate is mainly monomeric and also gains sheet content at the apparent expense of helix content. Tertiary structure analyses suggest that passage through the membranes induces bGH to adopt a more compact form than the bGH in either the feed or retentate streams. At both pHs 4 and 9, the less wettable PES membrane induces a greater structural change in the permeating bGH than does the more wettable RC membrane. Alkaline pH also tends to preserve the structure of bGH in the retentate streams, perhaps reflecting the extensive dimerization. Our results suggest that the choice of filtration conditions is critical in preserving protein structure and, hence, bioactivity.
Extracellular Superoxide Dismutase Attenuates Lipopolysaccharide-Induced Neutrophilic Inflammation (2004)

Extracellular superoxide dismutase (EC-SOD) is an abundant antioxidant in the lung and vascular walls. Previous studies have shown that EC-SOD attenuates lung injury in a diverse variety of lung injury models. In this study, we examined the role of EC-SOD in mediating lipopolysaccharide (LPS)-induced lung inflammation. We found that LPS-induced neutrophilic lung inflammation was exaggerated in EC-SOD-deficient mice and diminished in mice that overexpressed EC-SOD specifically in the lung. Similar patterns were seen for bronchoalveolar lavage cytokines, such as tumor necrosis factor-alpha, keratinocyte-derived chemokines, and macrophage inflammatory protein-2 as well as expression of lung intercellular adhesion molecule-1, vascular cell adhesion molecule-1, endothelial cell selectin, and platelet selectin. In a macrophage cell line, EC-SOD inhibited LPS-induced macrophage cytokine release, but did not alter expression of intercellular adhesion molecules in endothelial cells. These results suggest that EC-SOD plays an important role in attenuating the inflammatory response in the lung most likely by decreasing release of proinflammatory cytokines from phagocytes.
Design and Synthesis of 1-Indol-1-yl-propan-2-ones as Inhibitors of Human Cytosolic Phospholipase A2α (2006)

The synthesis and structure-activity relationship study of a series of 1-indol-1-yl-3-phenoxypropan-2-one inhibitors of cytosolic phospholipase A(2)alpha (cPLA(2)alpha) are described. The compounds were evaluated in a vesicle assay with isolated cPLA(2)alpha and in cellular assays with intact human platelets. Systematic variation led to 3-methylhydrogen 1-[3-(4-decyloxyphenoxy)-2-oxopropyl]indole-3,5-dicarboxylate (57), which revealed the highest activity against the isolated enzyme. With an IC(50) value of 4.3 nM in this assay, it is one of the most potent in vitro cPLA(2)alpha inhibitors known today.
The COVID States Project #71: Childhood COVID-19 vaccine uptake and intentions (2021)

In early November 2021, children ages 5-11 were authorized by the Centers for Disease Control and Prevention (CDC) to receive the Pfizer-BioNTech COVID-19 vaccine, making an additional 28 million children eligible for the shot. Given this significant advancement in COVID-19 vaccine availability - particularly in light of recent concerns over the Omicron variant - in this report we examine parent-reported COVID-19 vaccination intentions and uptake for children.Below, we examine reported childhood vaccination rates by childhood age and across different parent demographic subgroups. Additionally, we report parents’ expressed likelihood of vaccinating their children against COVID-19 across five survey waves from February, April, June, September, and November 2021.
Bitstream Binding Language &#8211; Mapping XML Multimedia Containers into Streams (2005)

Bitstream binding language (BBL) provides an abstraction layer between XML multimedia containers and the way their resources and metadata are published in a bitstream. It allows multiple bindings from a single source document to facilitate interoperability and applicability of the multimedia content to a wide range of terminals and users. BBL introduces a number of features not found in other XML fragmentation techniques-such as support for random-access-and provides a highly general framework for combining metadata with multimedia content in a transport format. This paper presents an overview of BBL and provides details of a Java implementation using the MPEG-21 multimedia framework as a sample application
Dynamics of a model for brain tumors reveals a small window for therapeutic intervention (2004)

Glioblastomas are the most malignant and most common glioma, a type of primary brain tumor with the unfortunate ability to recur despite extensive treatment. Even with the advent of medical imaging technology during the last two decades, successful treatment of glioblastomas has remained elusive. It has become increasingly clear that, along with the proliferative potential of these neoplasms, it is the subclinically diffuse invasion of glioblastomas that primarily contributes to their resistance to treatment. In other words, the inevitable recurrence of these tumors is the result of diffusely invaded but invisible tumor cells peripheral to the abnormal signal on medical imaging and to the current limits of surgical, radiological and chemical treatments. <br> Mathematical modeling has presented itself as a viable tool for studying complex biological processes (Murray, 1993, 2002). We have developed a mathematical model that portrays the growth and extension of theoretical glioblastoma cells in a matrix that accurately describes the brain's anatomy to a resolution of 1 cu mm (Swanson, et al, 1999, 2000, 2002, 2003a, 2003b). The model assumes that only two factors need be considered for such predictions: net growth rate and infiltrative ability. The model has already provided illustrations of theoretical glioblastomas that not only closely resemble the MRIs (magnetic resonance imaging) of actual patients, but also show the distribution of the diffusely infiltrating cells.

Quercetin Glycosides Improve Motor Performance and Muscle Weight in Adult Mice (2019)

Male C57BL/6J (B6) mice aged 24 weeks were provided two concentrations (1.5 or 3.0 g/L) of quercetin glycosides (QG) in drinking water over the subsequent 24 weeks. The objective was to determine if QG could improve motor function during early stages of aging. No sustained significant differences in body composition or food intake were noted to confirm the safety of QG treatment. Treated mice had significantly improved performance in grip strength and rotarod tests but not in treadmill performance. The functional benefits were reflected in muscle morphology with increased wet weights of a selected group of muscles (quadratus femoris, gastrocnemius, tibialis anterior, and soleus) in treated mice. Thus, it would appear that long-term oral treatment with QG can safely and effectively improve selected elements of motor performance and increase muscle mass during the early stages of aging.
Computer‐aided process analysis and economic evaluation for biosynthetic human insulin production—A case study (1995)

Human insulin was the first mammalian protein produced in bacteria using recombinant DNA technology. Two technologies were developed; the first based on the separate expression of precursors of chains A and B of insulin, and the second based on the expression of a precursor of proinsulin as a Trp-E fusion protein. Both technologies utilized Escherichia coli as an expression system. Later, a third technology was developed based on a strain of yeast that can secrete a precursor of insulin. The second E. coli process, a variation of which has been commercialized by Eli Lilly and Co., is analyzed in this article from a process design and economic evaluation viewpoint. The objective of this work is to elucidate the technical complexity and high cost associated with the manufacturing of biopharmaceuticals. Human insulin is a good example of a protein-based biopharmaceutical produced in large quantities (a fex tons per year) that requires large scale equipment and presents a multitude of scale-up challenges. Based onthe analysis, a number of conclusions are drawn regarding the cost breakdown and cost dependency on process parameters. Recommendations are made for cost reduction and environmental impact minimization. This analysis was performed using a software tool for computer-aided bioprocess design.

Spatially Scalable Video Coding For HEVC (2012)

Spatially scalable video coding (SSVC) provides an efficient way to transmit one video at different resolutions. Based on the emerging High Efficiency Video Coding (HEVC), we propose an SSVC scheme to support both single-loop (SL) and multiloop (ML) solutions by enabling different interlayer prediction mechanisms. Specifically, we employ two interlayer prediction modes: quadtree-based prediction mode (Q-mode) and learning-based prediction mode (L-mode). The Q-mode is investigated to exploit the interlayer redundancy based on the quadtree coding structure of HEVC. Due to the high correlation between layers, Q-mode utilizes the coded information from the base layer quadtree, including coding unit split, prediction unit partition, motion information, and partial texture information of transform unit, to predict the enhancement layer quadtree. By enabling Q-mode, we provide a basic SL solution for low complexity applications. Besides the correlation explored in Q-mode, we employ an extra L-mode to further improve the coding performance. In L-mode, the temporal-spatial correlation is exploited simultaneously by visual patch-based learning and mapping at pixel level. This helps us achieve more accurate prediction signals based on the coarse base layer reconstruction within an ML structure. Experimental results show the effectiveness of our SSVC scheme compared with the simulcast case and other HEVC-based SSVC schemes.
Prediction of liver toxicity and mode of action using metabolomics in vitro in HepG2 cells (2017)

Liver toxicity is a leading systemic toxicity of drugs and chemicals demanding more human-relevant, high throughput, cost effective in vitro solutions. In addition to contributing to animal welfare, in vitro techniques facilitate exploring and understanding the molecular mechanisms underlying toxicity. New 'omics technologies can provide comprehensive information on the toxicological mode of action of compounds, as well as quantitative information about the multi-parametric metabolic response of cellular systems in normal and patho-physiological conditions. Here, we combined mass-spectroscopy metabolomics with an in vitro liver toxicity model. Metabolite profiles of HepG2 cells treated with 35 test substances resulted in 1114 cell supernatants and 3556 intracellular samples analyzed by metabolomics. Control samples showed relative standard deviations of about 10-15%, while the technical replicates were at 5-10%. Importantly, this procedure revealed concentration-response effects and patterns of metabolome changes that are consistent for different liver toxicity mechanisms (liver enzyme induction/inhibition, liver toxicity and peroxisome proliferation). Our findings provide evidence that identifying organ toxicity can be achieved in a robust, reliable, human-relevant system, representing a non-animal alternative for systemic toxicology.
