User-oriented affective video content analysis (2002)

The article looks into a new direction in multimedia content analysis: the extraction and modeling of the affective content of an arbitrary video. The affective content is viewed as the amount of feeling/emotion contained in and mediated by a video toward a viewer. The ability to automatically extract video content of this nature will lead to a high level of personalization in broadcast delivery to private users, as well as considerably broadening the possibilities of efficiently handling and presenting large amounts of audio-visual data stored in emerging video databases. The technique we have developed uses the so-called "dimensional approach to affect" concept underlined by psychophysiology studies. Our computational method sets to represent the affective content as feature points in the so-called 2D emotion space. We manage to obtain time curves that represent the two affect dimensions (arousal and valence) for a video, considered respectively, from low-level video characteristics. Combining the two time curves results in the so-called affect curve that is regarded as a reliable representation of transitions from one feeling to another along a video, as perceived by a viewer. We illustrate the success of our technique on excerpts taken from an action movie and a typical soccer game, respectively.
Defined Single Strains of Lactic Streptococci in Bulk Culture for Cheddar and Monterey Cheese Manufacture (1980)

Acid production and Cheddar cheese quality were improved at three cheese plants when undefined commercial blends of'-lactic cultures were removed and replaced with phage insensitive, single strains propagated either in pairs or in one multiple blend of five or six strains. The paired strain program worked in one plant for over 12 mo with only six strains used during the last 7 mo. Two mutants replaced parent strains. The multiple blend worked for 6 mo in two plants with only one mutant replacing a parent strain. Careful phage-activity monitoring and strain selection were necessary to assure optimal success of the programs. A refrigerated reserve culture was used to provide back-up for the primary blend in the plant using the paired strain program. Make time and final cheese pH were more uniform than when undefined culture blends were used.
Altimetry using gnss reflectrometry for L5 (2012)

GNSS reflectrometry offers a low cost alternative for Earth remote sensing and is used to measure, for example, ocean altimetry, wind speed, wind direction and modeling of the ocean surface state. A bistatic configuration, using one right-handed circular polarized and one left-handed circular polarized antenna, was built for this experiment in order to measure direct and reflected L1 and L5 signals. The direct and reflected signals were compared and the path difference between them calculated, leading to altitude measurements with both L1 and L5 signals. Compared to publicly available signals on L1, the higher code rate of L5 will provide higher measurement sensitivity.
<title>Night pilotage assessment of image fusion</title> (1995)

The U.S. Army is currently investigating the pilotage benefits of fusing imagery from infrared and image intensified sensors for tactical night terrain display missions. This program just completed 7 months of night helicopter flight tests and analysis of the performance of a proprietary real-time image fusion system. This paper provides an overview of the program, flight test, and results.
The sonochemical synthesis and characterization of Cu<sub>1−<i>x</i></sub>Ni<sub><i>x</i></sub>WO<sub>4</sub>nanoparticles/nanorods and their application in electrocatalytic hydrogen evolution (2009)

Cu(1-x)Ni(x)WO(4) (x = 0.0, 0.2, 0.4, 0.6, 0.8, and 1.0) nanoparticles/nanorods have been prepared by a novel sonochemical method using cetyltrimethylammonium bromide (CTAB) as the structure directing agent. The prepared materials have been characterized by thermogravimetric analysis (TGA), x-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM), and BET specific surface area. The electrocatalytic activity towards the hydrogen evolution reaction (HER) has been studied for the Ni(2+)-substituted CuWO(4) nanoparticles by using linear sweep voltammogram measurements in a 1 M H(2)SO(4) solution. Cu(0.4)Ni(0.6)WO(4) (-473 mA cm(-2) at -1 V) shows a better catalytic activity than native CuWO(4) (-300 mA cm(-2) at -1 V).

Cell Proliferation Induction: Healing Chronic Wounds Through Low-Energy Pulsed Radiofrequency (2009)

Chronic lower extremity wounds are a major source of morbidity and health care expenditure across the world. In the last decade, numerous advanced modalities have become available that can help expedite wound healing when standard wound care modalities are unsuccessful. In this case report, the authors present their early experience with one such modality that uses pulsed radiofrequency energy to initiate cell proliferation induction in chronic lower extremity wounds of different etiologies that had failed to respond to standard therapy.
<title>Probe of pulse amplitude of electromagnetic field for investigation of GPR antenna performance</title> (2000)

In this report universal probe of electromagnetic field amplitude is described. The probe is intended for measurements of GPR antenna radiation in upper hemisphere as well as under ground surface. Goedbloed (1991) and de Jongh (1998) used analogous probe for measuring GPR antenna radiation pattern in lower hemisphere. The method described there is not flexible enough and narrows the range of measured parameters (depth of probe is fixed). Here we propose universal EM field probe and method for its use. Such sensor may also be used for in situ measurements of main parameters of sounded ground: (Gamma) <SUB>0</SUB> -- linear absorption and (nu) -- EM wave propagation velocity in ground. Example of such probe use is given below.
Low frequency noise in AlInAs/InGaAs/InP HFETs (2002)

We report on a measurement of low frequency noise in InP based HFETs, fabricated on MOCVD and MBE grown materials. The obtained spectral density of the drain current fluctuations is close to the pure flicker noise. An analysis of the results indicates that low frequency noise mainly stems from the carrier number fluctuations. An effective density of traps was found less than 10/sup 10/ ev/sup -1/ cm/sup -2/. Input referred noise of MBE grown InP HFETs was compared with that of MGF4419 and Philips D01PH HFETs. The low frequency noise of InP based device lies in the range of good commercially available GaAs HFETs.
<title>Revitalizing the scatter plot</title> (2000)

Computer-assisted interactive visualization has become a valuable tool for discovering the underlying meaning of tabular data, including categorical tabular data. The capabilities of the more traditionally mundane kinds of pictures like scatter plots can be expanded to usefully depict categorical tabular data by incorporating annotations and transforms, and by integrating the extensions into an interactive system.
Active learning for part-of-speech tagging (2007)

In the construction of a part-of-speech annotated corpus, we are constrained by a fixed budget. A fully annotated corpus is required, but we can afford to label only a subset. We train a Maximum Entropy Markov Model tagger from a labeled subset and automatically tag the remainder. This paper addresses the question of where to focus our manual tagging efforts in order to deliver an annotation of highest quality. In this context, we find that active learning is always helpful. We focus on Query by Uncertainty (QBU) and Query by Committee (QBC) and report on experiments with several baselines and new variations of QBC and QBU, inspired by weaknesses particular to their use in this application. Experiments on English prose and poetry test these approaches and evaluate their robustness. The results allow us to make recommendations for both types of text and raise questions that will lead to further inquiry.
Rational Development of β-Peptide Inhibitors of Human Cytomegalovirus Entry (2005)

Human cytomegalovirus (HCMV) is a pervasive and significant pathogen. At present, there is no HCMV vaccine, and the available drugs target only replication events. Thus, new therapeutic strategies are needed. HCMV fusion appears to require interactions of alpha-helical regions in viral surface glycoproteins gB and gH. Oligomers of beta-amino acids ("beta-peptides") are attractive unnatural scaffolds for mimicry of specific protein surfaces, because beta-peptides adopt predictable helical conformations and resist proteolysis. Here, we report the development of beta-peptides designed to mimic the gB heptad repeat and block HCMV entry. The most potent beta-peptide inhibits HCMV infection in a cell based-assay with an IC50 of approximately 30 microm. Consistent with our structure-based design strategy, inhibition is highly specific for HCMV relative to other related viruses. Mechanistic studies indicate that inhibitory beta-peptides act by disrupting membrane fusion. Our findings raise the possibility that beta-peptides may provide a general platform for development of a new class of antiviral agents and that inhibitory beta-peptides will constitute new tools for elucidating viral entry mechanisms.

Impaired neutralising antibody formation and high transduction efficacy after isolated hepatic perfusion with adenoviral vectors (2004)

Local adenoviral gene transfer can be performed by means of isolated hepatic perfusion (IHP). This methodology is a very effective and safe way to deliver adenoviral vectors. We studied the immune response after IHP. A decreased neutralising antibody formation was observed, offering possibilities for further research in the field of gene therapy in isolated perfusion settings.

Calcite mesocrystals: a very effective block polyelectrolyte for crystal "Morphing" (2009)

A family of calcite nanocrystal superstructures with unusual morphology were obtained from crystallization of calcite by the CO2 gas diffusion technique in the presence of a bioinspired double hydrophilic block copolymer, polyethyleneglycol-block-poly (L-aspartic acid). From the typical calcite rhombohedra as a starting situation, the morphology can be systematically varied via various unusual porous mesocrystal morphologies to hemispheres composed of fine calcite triangles. The formation of mesocrystals is starting at a polymer concentration of only 10-3 g/L and shows two remarkable results: (a) the reported bio-inspired block copolymer is the so far most active polymer for mesocrystal formation reported to our knowledge, and (b) the data prove that nucleation promoters exist, which can form nanocrystals for mesocrystal formation even without enhanced colloidal stabilization. This gives mesocrystal formation a much broader operation range than previously assumed.
Randomized, Open-Label Phase III Trial of Docetaxel Plus High-Dose Calcitriol Versus Docetaxel Plus Prednisone for Patients With Castration-Resistant Prostate Cancer (2011)

ASCENT treatment was associated with shorter survival than the control. This difference might be due to either weekly docetaxel dosing, which, in a prior study, showed a trend toward inferior survival compared with an every-3-weeks regimen, or DN-101 therapy.
Prognostic significance of estrogen receptor expression in ovarian cancer. Immunoreactive Score (IRS) vs. Composition Adjusted Receptor Level (CARL). (1994)

An Immunoreactive Score (IRS) was compared to the Composition Adjusted Receptor Level (CARL) evaluating prognostic significance of estrogen receptor (ER) expression in 61 ovarian cancers after > or = 8 years. CARL of ER allowed for calculating individual risk curves in stage III and IV, Grade 2 and 3, serous ovarian carcinoma after surgical debulking to < or = 2 cm residual and platinum based chemotherapy. In overall analysis and in subsets defined by tumor stage, grade or a combination thereof significant prognostic distinction became possible using a cutoff IRS of 4 vs. 0 or vs. scores < or = 3. This study substantiates ER as a prognostic variable in human ovarian cancer and for the first time establishes the value of an IRS.
Low-complexity DoA estimation based on Hermitian EVDs (2016)

The use of a receiving array of antennas allows the system to localize multiple sources. This estimation is sometimes simplified to a direction-of-arrival (DoA) estimation. The covariance-based (CB)-DoA algorithm is a lower complexity alternative to the ESPRIT algorithm, and yet achieves similar mean-squared error (MSE) with the same geometrical constraints. This article proposes a lower complexity CB-DoA algorithm. In the proposed algorithm, the eigenvector decomposition (EVD) of a non-Hermitian matrix is substituted by two lower complexity Hermitian EVDs. The replacement of EVDs does not imply MSE degradation. Discussions on exploiting the independent processing of the new EVDs are also provided.
Possible Participation of Angiotensin II Receptor Subtype 1 in Development of Hypertension (1993)

Abstract Angiotensin II (Ang II) is one of the major important factors operating in the pressor system in the regulation of blood pressure. Many investigators have suggested that locally generated Ang II plays an important role in this system. Thus, we examined the change in the expression of Ang II receptors, particularly subtype 1 (AT 1 ), in response to Ang II in isolated aortic strips during development of hypertension in spontaneously hypertensive rats (SHR) in comparison with that in Wistar Kyoto rats (WKY). A radioligand receptor binding assay was used to determine the number of Ang II receptors and to characterize the percentages of AT 1 receptors in the aorta at three developmental ages: 3, 6, and 30 weeks. The number of Ang II receptors ( B max ) in the SHR was similar to that in WKY and decreased with age in both SHR and WKY. However, the number of AT 1 receptors was higher (57.1, 45.5 and 42.0 fmol/mg protein, respectively) in SHR than in the WKY (33.4, 23.7, and 25.8 fmol/mg protein) at the three ages examined. The pD 2 value for Ang II-induced contractions was 9.35 in SHR and 8.85 in WKY at 3 weeks of age. In addition, the maximum developed tension in the aorta of SHR (30.2 mg/mg tissue) was significantly higher than that in WKY (21.8 mg/mg tissue). These findings suggest that the vascular renin-angiotensin system, at a young age before the development of high blood pressure, is activated and participates in the development of hypertension in SHR.
Folylpolyglutamate synthetase as a target for therapeutic intervention (2003)

The antifolate methotrexate (MTX). which targets the folate-dependent enzyme dihydrofolate reductase (DHFR), has been used effectively in cancer chemotherapy for over 50 years. Extensive efforts have been mounted to develop DHFR inhibitors that are more selective and/or have a wider tumor range than MTX and to develop inhibitors of other folate-dependent enzymes, principally thymidylate synthase and the enzymes of de novo purine synthesis. To date, these efforts have met with limited success. Another potential pathway for exploitation is the synthesis of polyly-glutamyl) forms of reduced folates. Folylpolyglutamates are essential for folate-medlated one-carbon metaboiism to function and hence are essential for cell survival. Thus, folylpolyglutamate synthetase (FPGS), which is responsible for synthesis of these metabolites, is suggested as a target for drug development. This article reviews the rationale for synthesis of FPGS inhibitors and the progress to date in developing potent, cell-permeable inhibitors of this critical enzyme.
Drag Measurements of Porous Plate Acoustic Liners (2005)

This paper presents the results of direct drag measurements on a variety of porous plate acoustic liners. The existing literature describes numerous studies of drag on porous walls with injection or suction, but relatively few of drag on porous plates with neither injection nor suction. Furthermore, the porosity of the porous plate in existing studies is much lower than typically used in acoustic liners. In the present work, the acoustic liners consisted of a perforated face sheet covering a bulk acoustic absorber material. Factors that were varied in the experiment were hole diameter, hole pattern, face sheet thickness, bulk material type, and size of the gap (if any) between the face sheet and the absorber material.

Babcock and Wilcox assessment of the Pratt and Whitney XNR2000 (1993)

Babcock & Wilcox performed four subtasks related to the assessment of the Pratt & Whitney XNR2000 nuclear reactor as follows: (1) cermet fuel element fabricability assessment; (2) mechanical design review of the reactor system; (3) neutronic analysis review; and (4) safety assessment. The results of the mechanical and physics reviews have been integrated into the reactor design. The results of the fuel and safety assessments are presented.
Stable spatially periodic patterns of ion channels in biomembranes (1995)

Ion flow through channels in a membrane may cause lateral gradients of the electrical potential which give rise to electrophoresis of charged channels. Coupled dynamics of the channel density and of the voltage across the membrane together with a binding-release reaction for the proteins leads via a pattern forming instability into a spatially periodic channel density. We derive near the onset of the spatial periodic pattern a Ginzburg-Landau equation and determine the parameter ranges with continuous transitions to periodic patterns. Above such a continuous transition the periodic patterns are stable within a wave-number band and within a finite range of the control parameter.
Effect of conformal roughness on ferromagnetic resonance linewidth in thin Permalloy films (2005)

The ferromagnetic resonance linewidth is a result of both intrinsic damping and contributions from inhomogeneities, which in thin films can be dominated by the roughness. Microstructural measurements and magnetization dynamics are reported here for 50-nm films of Permalloy deposited on substrates with controlled roughness. Ferromagnetic resonance measurements reveal a strong linewidth broadening that peaks when the magnetization is approximately 30° from the in-plane direction. These results are compared with a recently developed two-magnon theory of resonance broadening due to inhomogeneous demagnetizing fields in a rough film.
B-type natriuretic peptide as a marker for sepsis-induced myocardial depression in intensive care patients* (2008)

These results indicate that plasma BNP concentration represents a reliable marker for identification of patients developing sepsis-induced myocardial depression. In addition, BNP concentration on day 5 may be used as a prognostic marker to identify patients with an elevated risk for an adverse outcome.
Enhancing capacities of riparian professionals to address and resolve transboundary issues in international river basins: experiences from the Lower Mekong River Basin (2012)

Abstract. This paper analyses the design and impact of capacity building programmes aimed at enhancing capacities of riparian professionals to address and resolve transboundary issues in international river basins. The case study is a programme developed by the Mekong River Commission (MRC). A post-training evaluation was applied to assess its impact in terms of individual capacity enhancement and change (use and application of knowledge, factors hampering application, and change in function and opportunities within the organisation). The design of the Capacity Building Programme of the MRC Flood Management and Mitigation Programme required a well balanced range of subjects (such as IWRM (integrated water resources management), model and decision support systems, and international water law). The post-training evaluation, 6 months after the last training workshop, showed an increase in familiarity with the topics for all 37 respondents, with the highest increase for the respondents with few years of working experience and from training and education institutions. The relevance of the subjects taught was highlighted by 95% of the respondents, and 78% of the participants had already used some of the acquired knowledge in their job. The respondents indicated that they did not have sufficient opportunities to apply all knowledge. The phased implementation and training of lecturers during the training workshops had a good impact, directly through increasing involvement in facilitation and delivery of the capacity building programme and through the use of the knowledge gained in short courses and development of curricula at their institute. For these types of capacity building programmes, a few recommendations can be made. The selection of participants is crucial for the application of the learned knowledge in their work. The integrative nature of transboundary water issues calls for a capacity building programme addressing a wide range of subjects, which can be understood by a wide range of professionals from different sectors. Training methods should also address this integrative nature through, e.g. roleplays and case studies. A successful capacity building programme needs to address the three levels of capacity building (enabling environment, organisations, and individual staff) and involve national and regional training and education institutes.
