Surfactant Enhanced Mobilization of Nonaqueous Phase Liquids in Porous Media (2019)

Aquifers with dense nonaqueous phase liquids (DNAPLs) are difficult to remediate, due to the limited solubility of many DNAPLs in water and the immobility of residual DNAPLs at typical flow conditions of aquifers. Surfactant can be used to dramatically reduce remediation times via increased solubilization through micellar partitioning, increased mobilization through reductions in interfacial tension, or a combination of both. Different mobilization regimes result during surfactant flushing, but have not been examined for DNAPLs. Particular regimes are more easily controlled and are therefore preferred during surfactant flushing. Systems were studied in which capillary, viscous, and buoyancy forces were important to determine the critical conditions that lead to the different mobilization regimes during surfactant flushing. In these experiments, a 1:1 mixture of two food-grade, anionic surfactants, sodium diamyl sulfosuccinate and sodium dioctyl sulfosuccinate, were selected for the surfactant flushing solution, and tetrachloroethylene, a representative groundwater pollutant, was selected as the DNAPL. Experiments were conducted in two well-characterized cells packed with glass beads. Explanations of the mobilization regimes are given using a dimensionless grouping of system parameters (defined as the bank number). Because the bank number relies on general physical and chemical properties, it should be applicable to flushing of any homogeneous porous media. The pore-scale observations of this work have important implications concerning numeric simulations. The flow mechanism(s) that occur during flushing are important for determining the appropriate relative permeability function(s) used in numeric simulations.
SDS—PAGE strongly overestimates the molecular masses of the neurofilament proteins (1984)

Direct molecular mass determination of the three porcine neurofilament proteins (H, M and L) was performed in 6 M guanidine-HCl using analytical gel filtration and sedimentation equilibrium centrifugation. The results show that SDS-PAGE strongly overestimates the values of the 'higher molecular mass' components H and M. This discrepancy stems from the carboxyterminal extensions known to have unusual amino acid composition.
HgCdTe heterojunctions (1983)

HgCdTe heterojunctions consisting of a wide band gap n-type Hg1−xCdxTe layer grown epitaxially on a narrow band gap p-type Hg1−yCdyTe substrate (x&gt;y) were studied. The heterojunction transition region between x and y materials was found to be graded over distances of about 0.4 to 0.8 μm. The position of the p–n junction depletion layer within the graded transition region was the major factor controlling the heterojunction properties. When the depletion layer was located near the narrow band gap material, normal photodiode behavior was observed. When the depletion layer was at the center of the transition region or near the wide band gap material, a potential barrier was formed which inhibited minority carrier photocurrent originating in the p-type material from crossing the heterojunction. Qualitative energy band models based on the analysis of HgCdTe heterojunctions recently published by Migliorato and White were constructed to explain the observed results.
A model-based method for building reconstruction (2003)

Model-based reconstruction methods are applied to the detailed reconstruction of buildings from close-range images. The 3D points obtained through image matching are segmented into a coarse polyhedral model with a robust regression algorithm, then the geometry of this model is refined with predefined shape templates in order to automatically recover a CAD-like model of the building surface. Reprojection of the 3D shape templates is used to optimally fit their parameters to the image information. Throughout the paper the investigated methods are demonstrated on real datasets.
Abstractive Meeting Summarization with Entailment and Fusion (2013)

We propose a novel end-to-end framework for abstractive meeting summarization. We cluster sentences in the input into communities and build an entailment graph over the sentence communities to identify and select the most relevant sentences. We then aggregate those selected sentences by means of a word graph model. We exploit a ranking strategy to select the best path in the word graph as an abstract sentence. Despite not relying on the syntactic structure, our approach significantly outperforms previous models for meeting summarization in terms of informativeness. Moreover, the longer sentences generated by our method are competitive with shorter sentences generated by the previous word graph model in terms of grammaticality. 1
SSVM: a simple SVM algorithm (2003)

We present a fast iterative algorithm for identifying the support vectors of a given set of points. Our algorithm works by maintaining a candidate support vector set. It uses a greedy approach to pick points for inclusion in the candidate set. When the addition of a point to the candidate set is blocked because of other points already present in the set, we use a backtracking approach to prune away such points. To speed up convergence we initialize our algorithm with the nearest pair of points from opposite classes. We then use an optimization based approach to increase or prune the candidate support vector set. The algorithm makes repeated passes over the data to satisfy the KKT constraints. The memory requirements of our algorithm scale as O(|SI|/sup 2/) in the average case, where |S| is the size of the support vector set. We show that the algorithm is extremely competitive as compared to other conventional iterative algorithms like SMO and the NPA. We present results on a variety of real life datasets to validate our claims.
Monolithic AlAs-InGaAs-InGaP-GaAs HRT-FETS with PVCR of 960 at 300 K (2005)

This letter reports the significant N-shaped negative-differential resistance characteristics with three-terminal controllability of a monolithic heterostructure resonant tunneling field-effect transistor, realized by integrating the AlAs-In/sub 0.25/Ga/sub 0.75/As-AlAs double-barrier single-well resonant tunneling (RT) structure into the drain regime of the In/sub 0.49/Ga/sub 0.51/P-In/sub 0.25/Ga/sub 0.75/As-GaAs /spl delta/-high-electron mobility transistor. A peak-to-valley current ratio in excess of 960 at room temperature has been demonstrated, with a peak current density (J/sub p/) of 50.6 mA/mm, and a valley current density (J/sub v/) of 52.7 μA/mm, respectively, with a transistor gate length of 1.0 μm. The maximum current drive density was observed to be 478 A/mm-cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .
SAFE REACTION OF A ROBOT ARM WITH TORQUE SENSING ABILITY ON THE EXTERNAL DISTURBANCE AND IMPACT: IMPLEMENTATION OF A NEW VARIABLE IMPEDANCE CONTROL (2008)

The paper focuses on control of a new anthropomorphic robot arm enabling the torque measurement in each joint to ensure safety while performing tasks of physical interaction with human and environment. A novel variable control strategy was elaborated to increase the robot functionality and to achieve human-like dynamics of interaction. The algorithm of impact control imparting reflex action ability to the robot arm was proposed. The experimental results showed successful recognition and realization of three different types of interaction: service task, co-operative task, and impact state.
Flexural Characteristics of a Cantilever Plate Subjected to Heating at Fixed End (2009)

Abstract The flexural characteristic of a cantilever plate, which is heated from a fixed end, is considered and the effects of heat transfer on the plate are examined. The plate is heated with a temperature source while an excitation force is applied at the free end. Size of heat source is varied and temperature dependent properties of the plate are accommodated in the simulations. The finite element method (FEM) is adopted to determine the temperature field in the plate and flexural characteristics due to the applied impulsive load. It is found that the flexural characteristics of the plate change notably with the size of the heat source located at the fixed end of the plate. In this case, increasing the size of the heat source results in the enhancement of the amplitude and time shift in the flexural motion of the plate due to the heating and noheating situations.
REPORTS (1950)

In order that the thoughts and the fellowship of the 1950 Biennial Convention of the Religious Education Association may be shared more widely three papers and the reports of four discussion groups are presented in this issue The first paper needs a special introduction. This is an address which Harrison S. Elliott gave at a banquet which two hundred and fifty of his friends attended in his honor at Christ Church, New York City, on May 1, 1950. This occasion had a two‐fold significance; it was a testimonial to his twenty‐eight years of service at Union Theological Seminary, where he was Professor of Religious Education and Psychology; and it was also in honor of his inauguration into the General Secretaryship of the Religious Education Association. This address was a high point in the Biennial Convention ‐‐ The Editorial Committee
Pharmacokinetics and analgesic effects of intravenous buprenorphine (2005)

Background buprenorphine (BUP), a semi-synthetic opioid, is used as an analgesic for post-operative and chronic pain. Because of very low plasma concentrations its pharmacokinetics and related pharmacodynamics are not well characterized. BUP pharmacokinetics and pharmacodynamics were investigated as part of a study on the efficacy of naltrexone (NTX) in reversing its analgesic effects. Methods randomized double-blind placebo-controlled cross-over study in 12 healthy male volunteers who received 0.15 mg/70 kg BUP iv. Data were collected up to 8 hours after drug administration. Quantitative sensory testing, using thermal and electrical stimulations (Viking IV, Madison USA), and testing for pain tolerance (cold pressor) were performed. Plasma concentrations of BUP were quantified by liquid chromatography-tandem mass spectrometry. The limit of quantification was 50 pg/mL. Results BUP significantly increased the nociceptive threshold and pain tolerance for the first 2 hours (p<0.05). A two compartment model adequately described BUP pharmacokinetics. The mean elimination half-life was 3.9h (CV=75%). Plasma clearance was 7.6 L/h (CV=83%), and AUC was 39h ng/mL (CV=87%). Conclusions a two compartment pharmacokinetic model adequately characterizes buprenorphine pharmacokinetics. Significant analgesic effects are observed during the distribution phase.

Robust expression of a bioactive mammalian protein in <i>Chlamydomonas</i> chloroplast (2007)

We have engineered the chloroplast of eukaryotic algae to produce a number of recombinant proteins, including human monoclonal antibodies, but, to date, have achieved expression to only 0.5% of total protein. Here, we show that, by engineering the mammalian coding region of bovine mammary-associated serum amyloid (M-SAA) as a direct replacement for the chloroplast psbA coding region, we can achieve expression of recombinant protein above 5% of total protein. Chloroplast-expressed M-SAA accumulates predominantly as a soluble protein, contains the correct amino terminal sequence and has little or no post-translational modification. M-SAA is found in mammalian colostrum and stimulates the production of mucin in the gut, acting in the prophylaxis of bacterial and viral infections. Chloroplast-expressed and purified M-SAA is able to stimulate mucin production in human gut epithelial cell lines. As Chlamydomonas reinhardtii is an edible alga, production of therapeutic proteins in this organism offers the potential for oral delivery of gut-active proteins, such as M-SAA.
THE USE OF RECURSIVE MEDIAN FILTERS FOR ESTABLISHING THE TONAL CONTEXT IN MUSIC (1998)

The recursive median filter is used to improve the structure of the output of the key finding algorithm for establishing tonal contexts of musical patterns in a musical composition. This is subsequently incorporated into a system for recognition of musical patterns. Krumhansl&apos;s key-finding algorithm is used as a basis. The sequence of maximum correlations that it outputs is smoothed with a cubic spline and is used to determine weights for perceptual and absolute pitch errors. Maximum correlations are used to create the assigned key sequence, which is processed by a recursive median filter. In most cases, the recursive median filter establishes the key more accurately than the standard median filter. Additionally, since the recursive median is idempotent, the key-finding output is guaranteed to be a root signal. INTRODUCTION Musical Pattern Recognition (MPR) is concerned with recognition or classification of musical patterns. Figure 2 shows a block diagram of the MPR system. It produc...
BuMP: Bulk Memory Access Prediction and Streaming (2014)

With the end of Den nard scaling, server power has emerged as the limiting factor in the quest for more capable data enters. Without the benefit of supply voltage scaling, it is essential to lower the energy per operation to improve server efficiency. As the industry moves to lean-core server processors, the energy bottleneck is shifting toward main memory as a chief source of server energy consumption in modern data enters. Maximizing the energy efficiency of today's DRAM chips and interfaces requires amortizing the costly DRAM page activations over multiple row buffer accesses. This work introduces Bulk Memory Access Prediction and Streaming, or BuMP. We make the observation that a significant fraction (59-79%) of all memory accesses fall into DRAM pages with high access density, meaning that the majority of their cache blocks will be accessed within a modest time frame of the first access. Accesses to high-density DRAM pages include not only memory reads in response to load instructions, but also reads stemming from store instructions as well as memory writes upon a dirty LLC eviction. The remaining accesses go to low-density pages and virtually unpredictable reference patterns (e.g., Hashed key lookups). BuMP employs a low-cost predictor to identify high-density pages and triggers bulk transfer operations upon the first read or write to the page. In doing so, BuMP enforces high row buffer locality where it is profitable, thereby reducing DRAM energy per access by 23%, and improves server throughput by 11% across a wide range of server applications.
Global Conformations, Hydrodynamics, and X-ray Scattering Properties of Taq and Escherichia coli DNA Polymerases in Solution (2003)

Escherichia coli polymerase 1 (Pol 1) and Thermus aquaticus Taq polymerase are homologous Type I DNA polymerases, each comprised of a polymerase domain, a proofreading domain (inactive in Taq), and a 5' nuclease domain. "Klenow" and "Klentaq" are the large fragments of Pol 1 and Taq and are functional polymerases lacking the 5' nuclease domain. In the available crystal structures of full-length Taq, the 5' nuclease domain is positioned in two different orientations: in one structure, it is extended out into solution, whereas in the other, it is folded up against the polymerase domain in a more compact structure. Analytical ultracentrifugation experiments report s20,w values of 5.05 for Taq, 4.1 for Klentaq, 5.3 for E. coli Pol 1, and 4.6 for Klenow. Measured partial specific volumes are all quite similar, indicating no significant differences in packing density between the mesophilic and thermophilic proteins. Small angle x-ray scattering studies report radii of gyration of 38.3 A for Taq, 30.7 A for Klentaq, and 30.5 A for Klenow. The hydrodynamic and x-ray scattering properties of the polymerases were also calculated directly from the different crystal structures using the programs HYDROPRO (Garcia De La Torre, J., Huertas, M. L., and Carrasco, B. (2000) Biophys J. 78, 719-730) and CRYSOL (Svergun, D. I., Barberato, C., and Koch, M. H. J. (1995) J. Appl. Crystalogr. 28, 768-773), respectively. The combined experimental and computational characterizations indicate that the full-length polymerases in solution are in a conformation where the 5' nuclease domain is extended into solution. Further, the radius of gyration, and hence the global conformation of Taq polymerase, is not altered by the binding of either matched primer template DNA or ddATP.
Transient Excitation of an Elastic Half Space by a Point Load Traveling on the Surface (1969)

The propagation of transient waves in a homogeneous, isotropic, linearly elastic half space excited by a traveling normal point load is investigated. The load is suddenly applied and then it moves rectilinearly at a constant speed along the free surface. The displacements are derived for the interior of the half space and for all load speeds. Wave-front expansions are obtained from the exact solution, in addition to results pertaining to the steady-state displacement field. The limit case of zero load speed is considered, yielding new results for Lamb’s point load problem.
<i>Mitigation Strategies to Reduce Acrylamide Formation in Fried Potato Products</i> (2008)

Potato products contain high amounts of acrylamide, which sometimes exceeds the concentration of 1 mg/L. However, many strategies for acrylamide reduction in potato products are possible. In this work, the different approaches for reducing acrylamide formation have been reviewed, keeping in mind that in the application of strategies for acrylamide formation, the main criteria to be maintained are the overall organoleptic and nutritional qualities of the final product.
Improving LoRa Network Capacity Using Multiple Spreading Factor Configurations (2018)

LoRa networks enable long range communications for Internet of Things (IoT) applications. The current LoRa technology provides a wide range of communication settings whereas many combination settings are orthogonal and, thus, they can be successfully decoded at the gateway when the signals are transmitted simultaneously. Previous simulation results showed that the LoRa network capacity can be improved when multiple communication parameters are applied. In this paper, we model a LoRa network consisting of nodes with different communication settings in terms of bandwidth and spreading factor. We compute the average success probability per configuration as a function of density taking into account both intra and inter-spreading factor collisions. We, also, formulate and solve an optimization problem to maximize the node capacity for a given deployment area and frequency by optimizing the number of nodes having different spreading factor configurations. We present numerical results and we show that solutions close to the optimal can increase the maximum number of nodes by more than 700% compared to case where equal number of users per spreading factor are considered.
p53 gene and Wnt signaling in benign neoplasms: β-catenin mutations in hepatic adenoma but not in focal nodular hyperplasia (2002)

Hepatocellular adenoma (HA) and focal nodular hyperplasia (FNH) are 2 rare, benign liver neoplasms that often are discovered incidentally. To date, few genetic changes have been found in these 2 benign lesions. However, the 2 pathways of p53 and Wnt signaling, which may be the most common molecular targets involved in liver tumorgenesis, were studied in HA and FNH. Ten HAs and 11 FNHs were analyzed for loss of heterozygosity (LOH) and sequencing analysis of mutation hot spots in exons 5 to 8 of the p53 gene. No LOH or mutant sequences were identified, indicating that p53 was not associated with these benign lesions. Genes in the Wnt signaling pathway, including beta-catenin, axin, and adenomatous polyposis coli (APC), also were studied. Polymerase chain reaction (PCR) amplification and direct sequencing of all samples of HA and FNH displayed no mutations in exon 3 of the beta-catenin gene. However, 3 HAs (30%) contained interstitial deletions from exon 3 to exon 4. Truncated forms of beta-catenin detected by Western blot and immunohistochemical analyses showed they had accumulated in the cytoplasm and nuclei. However, for the axin and APC genes, no genetic changes, including allelic loss, interstitial deletions and point mutations, were detected in any of the HAs and FNHs. In conclusion, beta-catenin, which participates in the Wnt signaling pathway, might play a more important role in the formation of HA than in that of FNH, but p53 is not associated with the development of either HA or FNH.
Expression levels of the microRNA maturing microprocessor complex component DGCR8 and the RNA‐induced silencing complex (RISC) components argonaute‐1, argonaute‐2, PACT, TARBP1, and TARBP2 in epithelial skin cancer (2011)

The microprocessor complex mediates intranuclear biogenesis of precursor microRNAs from the primary microRNA transcript. Extranuclear, mature microRNAs are incorporated into the RNA-induced silencing complex (RISC) before interaction with complementary target mRNA leads to transcriptional repression or cleavage. In this study, we investigated the expression profiles of the microprocessor complex subunit DiGeorge syndrome critical region gene 8 (DGCR8) and the RISC components argonaute-1 (AGO1), argonaute-2 (AGO2), as well as double-stranded RNA-binding proteins PACT, TARBP1, and TARBP2 in epithelial skin cancer and its premalignant stage. Patients with premalignant actinic keratoses (AK, n = 6), basal cell carcinomas (BCC, n = 15), and squamous cell carcinomas (SCC, n = 7) were included in the study. Punch biopsies were harvested from the center of the tumors (lesional), from healthy skin sites (intraindividual controls), and from healthy skin sites in a healthy control group (n = 16; interindividual control). The DGCR8, AGO1, AGO2, PACT, TARBP1, and TARBP2 mRNA expression levels were detected by quantitative real-time reverse transcriptase polymerase chain reaction. The DGCR8, AGO1, AGO2, PACT, and TARBP1 expression levels were significantly higher in the AK, BCC, and SCC groups than the healthy controls (P < 0.05). There was no significant difference in the TARBP2 expression levels between groups (P > 0.05). This study indicates that major components of the miRNA pathway, such as the microprocessor complex and RISC, are dysregulated in epithelial skin cancer.
