Political Speech Generation (2016)

In this report we present a system that can generate political speeches for a desired political party. Furthermore, the system allows to specify whether a speech should hold a supportive or opposing opinion. The system relies on a combination of several state-of-the-art NLP methods which are discussed in this report. These include n-grams, Justeson & Katz POS tag filter, recurrent neural networks, and latent Dirichlet allocation. Sequences of words are generated based on probabilities obtained from two underlying models: A language model takes care of the grammatical correctness while a topic model aims for textual consistency. Both models were trained on the Convote dataset which contains transcripts from US congressional floor debates. Furthermore, we present a manual and an automated approach to evaluate the quality of generated speeches. In an experimental evaluation generated speeches have shown very high quality in terms of grammatical correctness and sentence transitions.
Narrative and Persuasion in Fashion Advertising (2010)

Narrative transportation-to be carried away by a story-has been proposed as a distinct route to persuasion. But as originally conceived, narrative transportation is unlikely to occur in response to advertisements, where persuasive intent is obvious and consumer resistance is expected. We analyze fashion ads to show how narrative transportation can nonetheless be a possible response to ads, if specific aesthetic properties are present, most notably when grotesque imagery is used. We then situate narrative transportation as one of five modes of engaging fashion advertising, each of which serves as a distinct route to persuasion. Interviews showed that consumers variously engage ads to act, identify, feel, transport, or immerse. We explain how aesthetic properties of ads call forth different modes of engagement and explore how grotesque imagery can lead to either narrative transportation or immersion. As routes to persuasion, transportation and immersion work by intensifying brand experience rather than boosting brand evaluation. (c) 2010 by JOURNAL OF CONSUMER RESEARCH, Inc..
An 8 b fuzzy coprocessor for fuzzy control (1993)

A fuzzy coprocessor (FC) that is area- and speed-optimized and can be integrated as an on-chip microcontroller module is described. The performance of the FC is depicted. With 1000 rules and four inputs, the computation time is 126.5 mu s. The coprocessor is programmed with an evaluation board. The system under control is connected to the host microcontroller that is supported by the FC in fuzzy computing. For development purposes, the knowledge-base memory (KBM) is a separate device. It stores the rules and the membership functions of inputs and outputs and is programmed by development hardware that is the interface to a fuzzy development system. A list of design features is given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Het caseinaatphosphaatcomplex van melk (1961)

The properties of the complex of calcium phosphate and caseinate were studied by both analytical and synthetic methods. The first approach, based on a great number of analyses of milk from individual cows, demonstrated that the composition of the complex (ratio of the various components) was widely variable, and that also Mg, Na, K and citrate were part of it. Also the cationbinding capacity of casein was studied and found to depend on several factors. By simultaneous titration at constant pH of calcium hydroxide and phosphoric acid, a complex phosphate was precipitated (relation Ca/P about 1.4), which is neither an orthophosphate, nor a hydroxy-apatite. If this titration was in caseinate solutions, a 'complex' could be synthetized. Its properties were in most respects according to those of the complex of milk. Although no definite answer could be given to the problem of the kind of bond between caseinate and phosphate, some existing hypotheses could be ruled out. The complex phosphate has distinct ion-exchange properties.
Fragmentation of phospholipid bilayers by myelin basic protein (1994)

Human myelin basic protein (MBP) is shown to disrupt multilamellar phosphatidylcholine bilayers into small lipoprotein particles in a manner similar to the cytolytic peptide melittin (Dufourc, E. J., Smith, I. C. P., & Dufourcq, J. (1986) Biochemistry 25, 6448-6455). This bilayer fragmentation, as monitored by 31P nuclear magnetic resonance, is temperature-dependent and completely inhibited by the presence of small amounts of negatively charged phosphatidylserine. The stabilizing property of phosphatidylserine is lost with the neutralization of its negative charges upon membrane binding of cationic species such as calcium ions. No MBP-induced fragmentation is observed with bilayers of negative or zwitterionic lipid mixtures which mimic the myelin lipid composition. The membrane fragmentation observed in vitro in the presence of MBP could play a role in vivo in demyelinating diseases.
Autograft versus allograft in anterior cruciate ligament reconstruction (2016)

Autograft is superior to irradiated allograft for patients undergoing ACL reconstruction concerning knee function and laxity, but there are no significant differences between autograft and nonirradiated allograft. However, our results should be interpreted with caution, because the blinding methods were not well used.
Corrosion Protection of Cerium-Based Conversion Coatings with Subsurface Crevices (2010)

The corrosion protection of electrodeposited cerium-based conversion coatings (CeCCs) on AA 2024-T3 with and without subsurface crevices was investigated. Coatings that were otherwise identical provided significant corrosion protection with or without crevices, as long as a post-treatment was employed after crevice formation. During salt spray exposure, impedance of crevice-free coatings increased from an initial value of ~50 kΩ-cm2 to ~60 kΩ-cm2 after 96 hours of exposure. In contrast, the impedance of coatings containing crevices doubled after 24 hours to ~100 kΩ-cm2. The impedance increase for crevice-containing coatings was associated with the build up of oxides / hydroxides in the crevices, which limited direct contact between the electrolyte solution and the substrate. Crevice-free coatings exhibited active corrosion protection even though no oxide build up was observed. For CeCCs with or without crevices, corrosion protection appeared to occur due to the formation of an interfacial layer between the coating and the substrate.
Remote retail monitoring and stock assessment using mobile robots (2014)

This paper describes a Virtual Reality (VR) based system for automating data collection and surveying in a retail store using mobile robots. The manpower cost for surveying and monitoring the shelves in retail stores are high, because of which these activities are not repeated frequently causing reduced customer satisfaction and loss of revenue. Further, the accuracy of data collected may be improved by avoiding human related factors. We use a mobile robot platform with on-board cameras to monitor the shelves either autonomously or through tele-operation. A remote operator can control the robot from a console which shows a 3D of view of the store as well as, capture real images and videos of the store. The robot is designed to facilitate automatic detection of Out-of-Stock (OOS) situations. It would be possible for a single operator to control multiple robots placed at different stores thus optimizing the available resources. As the deployment of the proposed system does not require modifying existing infrastructure of the store, the cost of the entire solution is cheaper with shorter return-on-investment (ROI) period.
A Single Vaccination with Polyomavirus VP1/VP2Her2 Virus-Like Particles Prevents Outgrowth of HER-2/<i>neu</i>–Expressing Tumors (2005)

Murine polyomavirus (MPyV) VP1 virus-like particles (VLPs), containing a fusion protein between MPyV VP2 and the extracellular and transmembrane domain of HER-2/neu (Her2), Her2(1-683)PyVLPs, were tested for their ability to vaccinate against Her2-expressing tumors in two different in vivo models. Protection was assessed both against a lethal challenge with a BALB/c mammary carcinoma transfected with human Her2 (D2F2/E2) and against the outgrowth of autochthonous mammary carcinomas in BALB-neuT mice, transgenic for the activated rat Her2 oncogene. A single injection of Her2(1-683)PyVLPs before tumor inoculation induced a complete rejection of D2F2/E2 tumor cells in BALB/c mice. Similarly, a single injection of Her2(1-683)PyVLPs at 6 weeks of age protected BALB-neuT mice with atypical hyperplasia from a later outgrowth of mammary carcinomas, whereas all controls developed palpable tumors in all mammary glands. VLPs containing only VP1 and VP2 did not induce protection. The protection elicited by Her2(1-683)PyVLPs vaccination was most likely due to a cellular immune response because a Her2-specific response was shown in an ELISPOT assay, whereas antibodies against Her2 were not detected in any of the two models. The results show the feasibility of using MPyV-VLPs carrying Her2 fusion proteins as safe and efficient vaccines against Her2-expressing tumors.
A two-dimensional analysis of the sensitivity of a pulse first break to wave speed contrast on a scale below the resolution length of ray tomography (2016)

Mapping the speed of mechanical waves traveling inside a medium is a topic of great interest across many fields from geoscience to medical diagnostics. Much work has been done to characterize the fidelity with which the geometrical features of the medium can be reconstructed and multiple resolution criteria have been proposed depending on the wave-matter interaction model used to decode the wave speed map from scattering measurements. However, these criteria do not define the accuracy with which the wave speed values can be reconstructed. Using two-dimensional simulations, it is shown that the first-arrival traveltime predicted by ray theory can be an accurate representation of the arrival of a pulse first break even in the presence of diffraction and other phenomena that are not accounted for by ray theory. As a result, ray-based tomographic inversions can yield accurate wave speed estimations also when the size of a sound speed anomaly is smaller than the resolution length of the inversion method provided that traveltimes are estimated from the signal first break. This increased sensitivity however renders the inversion more susceptible to noise since the amplitude of the signal around the first break is typically low especially when three-dimensional anomalies are considered.

Biological Effects and Safety in Magnetic Resonance Imaging: A Review (2009)

Since the introduction of Magnetic Resonance Imaging (MRI) as a diagnostic technique, the number of people exposed to electromagnetic fields (EMF) has increased dramatically. In this review, based on the results of a pioneer study showing in vitro and in vivo genotoxic effects of MRI scans, we report an updated survey about the effects of non-ionizing EMF employed in MRI, relevant for patients' and workers' safety. While the whole data does not confirm a risk hypothesis, it suggests a need for further studies and prudent use in order to avoid unnecessary examinations, according to the precautionary principle.
Dopaminergic Stimulation of Pituitary but Not Hypothalamic Estrogen Receptors in Ovariectomized Rats* (1983)

This study was designed to examine the role of catecholamines and serotonin in the regulation of estrogen receptors (ER) in the medial basal hypothalamus (MBH) and anterior pituitary gland (AP) of adult ovariectomized rats. Plasma PRL and LH were also determined. Injection of alpha-methyl tyrosine (alpha-MT) resulted in the significant reduction of norepinephrine and dopamine (DA) content in the MBH, and of plasma LH levels as well as in the significant elevation of plasma PRL levels. This treatment also resulted in the significant reduction of ER concentration in the AP. The elevation in plasma PRL by alpha-MT was reversed by the simultaneous injection of bromocriptine (BC), a DA agonist, which also partially reversed the alpha-MT reduction of ER concentrations in the AP. BC had no effect on plasma LH levels. The ER concentration in the MBH was not significantly changed by any of these treatments. The reduction of serotonin content in the MBH by the injection of p-chlorophenylalanine had no effect on the ER concentration in either the MBH or AP, nor did it have any effect on plasma PRL levels. However, p-chlorophenylalanine treatment did decrease plasma LH levels. Neonatal treatment of female rats with monosodium glutamate which has been reported to destroy part of the MBH, resulted in a significant reduction in body and pituitary weight and in a significant elevation of plasma PRL levels in adults (2 months old). This treatment also resulted in a significant reduction in the AP and MBH ER concentration. Injection of BC to adults reversed the effects of neonatal monosodium glutamate treatment on plasma PRL levels and on the pituitary ER concentration, but had no effect on the ER concentration in the MBH. BC had no effect on the AP or MBH ER concentration in control rats, although it did as expected reduce the plasma PRL levels in these animals. Plasma LH levels were not significantly changed by any of these treatments. Injection of the DA antagonist, haloperidol, to adult rats resulted in a significant elevation of plasma PRL and in a significant reduction of ER concentration in the AP. Haloperidol treatment did not affect the binding affinity of these receptors. Overall, these data suggest that DA is involved with the regulation of ER in the AP.
Comparison of proto‐oncogenic and mutant forms of the transmembrane region of the Neu receptor in TFE (2002)

A single mutation within the transmembrane region of the Neu receptor (Val664-->Glu) is known to enhance tyrosine kinase activity, by promoting receptor dimerization. In order to gain insight into potential structural changes that arise as a result of the mutation, peptides corresponding to the complete transmembrane domain of proto-oncogenic and mutant forms of Neu have been studied by 1H nuclear magnetic resonance in the solvent trifluoroethanol (TFE). The chemical shifts are similar for both forms of the peptide, with the exception of amide residues close to the mutation site. Both peptides adopt a helical conformation, with a distinct bend one turn downstream of the mutation site. This deformation gives rise to several nuclear Overhauser effects, the majority of which were detected in both peptides, that are atypical for a straight canonical alpha-helix. Our data in this solvent do not support a conformational change in the transmembrane domain of monomeric Neu as a result of the mutation. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis indicates that proto-oncogenic Neu peptides have a higher propensity to oligomerize in the solvent TFE than the Glu664 oncogenic form.
Nonnegative matrix factorization with manifold structure for face recognition (2018)

Nonnegative matrix factorization (NMF) is a promising method to represent facial images using nonnegative features under a low-rank nonnegative basis-image matrix. The facial images usually reside on a low-dimensional manifold due to the variations of illumination, pose and facial expression. However, NMF has no ability to uncover the manifold structure of data embedded in a high-dimensional Euclidean space, while the manifold structure contains both local and nonlocal intrinsic features. These two kinds of features are of benefit to class discrimination. To enhance the discriminative power of NMF, this paper proposes a novel NMF algorithm with manifold structure (Mani-NMF). Two quantities related to adjacent graph and non-adjacent graph are incorporated into the objective function, which will be minimized by solving two convex suboptimization problems. Based on the gradient descent method and auxiliary function technique, we acquire the update rules of Mani-NMF and theoretically prove the convergence of the proposed Mani-NMF algorithm. Three publicly available face databases, Yale, pain expression and CMU databases, are selected for evaluations. Experiments results show that our algorithm achieves a better performance than some state-of-the-art algorithms.
Quantitative detection of human immunodeficiency virus (HIV) antigen by the Enzymun-Test: comparison with alternative assays and nucleic acid sequence-based amplification of HIV type 1 RNA (1996)

A new modular automated enzyme immunoassay (EIA) (Enzymun-Test HIV Ag: Boehringer Mannheim) for quantitative human immunodeficiency virus (HIV) antigen detection was evaluated by testing a panel of 1,506 serum samples, including seroconversions, dilution series, follow-up samples from patients under antiretroviral therapy, single serum specimens from HIV-seropositive individuals in different stages of infection, potentially cross-reactive samples, and sera from HIV-negative hospitalized patients. The Abbott HIV type 1 (HIV-1) antigen monoclonal antibody assay served as the reference assay, and nucleic acid sequence-based amplification (Organon Teknika) for quantitative amplification of HIV-1 RNA was used for follow-up of patients under antiretroviral chemotherapy. The Boehringer Mannheim and Abbott EIAs showed concordant results for the early detection of HIV antigen in all the seroconversion panels. The follow-up samples from 29 HIV-infected individuals under antiretroviral therapy gave divergent results between both antigen tests. For the detection of HIV antigen in single serum samples from HIV-infected patients in different stages of HIV infection, a higher number of positive samples was detected with the Abbott HIV-1 antigen monoclonal antibody assay in samples from patients in stages II and III of HIV infection. The Enzymun-Test detected three or more positive samples than did the Abbott assay among the samples of patients with AIDS. The concordance on a sample-to-sample basis between the Boehringer Mannheim and Abbott EIAs was 98.6%. The sensitivity of the Enzymun-Test in comparison to the reference assay was 97.2%; the specificity was 98.8%. Although no close correlation could be found between the amount of viral RNA in serum detected by nucleic acid sequence-based amplification and the concentration of HIV antigen, a high HIV-1 RNA copy number was mostly associated with high levels of HIV antigen. In conclusion, the Enzymun-Test permits accurate HIV antigen detection and offers, in contrast to previous assays, the possibility of completely automated detection.
Prothrombin requires two sequential metal-dependent conformational transitions to bind phospholipid. Conformation-specific antibodies directed against the phospholipid-binding site on prothrombin. (1986)

Prothrombin is a gamma-carboxyglutamic acid-containing protein that binds to phospholipid vesicles in the presence of calcium ions after undergoing a metal ion-induced conformational transition. To integrate recent data into a scheme that is compatible with our knowledge of prothrombin-metal interaction, we have proposed a new model of prothrombin structure. In this model prothrombin undergoes two metal-dependent conformational transitions: PT----PT'----PT*. The first transition is not cation-specific, but the second transition is metal-selective for Ca(II), Sr(II), or Ba(II). Only the PT* conformer binds to phospholipid surfaces. To test this model, anti-prothrombin antibodies that only bind to prothrombin in the presence of Ca(II) but not Mg(II) (PT*-specific) were isolated, and termed anti-prothrombin X Ca(II)-specific. Half-maximal binding of antibody to prothrombin was observed at 0.1 mM CaCl2 or 1 mM SrCl2, but no binding was observed with Mg(II), Mn(II), or Ba(II). However, prothrombin in the presence of both Mg(II)/Ba(II) or Mn(II)/Ba(II) demonstrated significant interaction with the antibody. Prothrombin binding to phospholipid vesicles was inhibited by the anti-prothrombin X Ca(II)-specific antibody or its Fab fragment, but was not inhibited by anti-prothrombin X Mg(II) antibody or its Fab fragment directed at the PT' conformer. These results support this three-state model for prothrombin. The metal specificity characteristic of prothrombin-phospholipid interaction is a property required for the expression of the phospholipid-binding site in the binary prothrombin-metal complex.
