Two modes of phase inversion in a drying emulsion (2013)

We report two different modes of phase inversion in surfactant-stabilized oil-in-water emulsions subjected to a unidirectional drying stress. Coalescence occurs either through a nucleation-and-growth mechanism, where coalesced pockets form and grow randomly throughout the sample, or through a coalescence front that propagates into the sample from the drying end. This drying-induced coalescence results from the development of a pressure gradient from the drying front into the bulk of the sample, established by limited water transport through the Plateau borders. Depending on the steepness of this pressure profile, coalescence occurs throughout the sample or only at the drying front. Moreover, we find that surfactant concentration plays a significant role through its effect on the critical disjoining pressure at which coalescence occurs. Very stable emulsions, characterized by a high critical pressure, tend to develop steep pressure profiles, which favours front-dominated coalescence, while unstable emulsions with low critical pressures develop shallow pressure gradients, favouring nucleation-and-growth dominated coalescence. These results offer new insights into the microscopic mechanisms governing the complex and poorly understood macroscopic phenomena during phase inversion of drying emulsions.
Revising the wordnet domains hierarchy (2004)

The continuous expansion of the multilingual information society has led in recent years to a pressing demand for multilingual linguistic resources suitable to be used for different applications.
Phenotypic Inflammation Switch in Rats Shown by Calcitonin Gene-Related Peptide Immunoreactive Dorsal Root Ganglion Neurons Innervating the Lumbar Facet Joints (2001)

The ratio of fluorogold-labeled, calcitonin gene-related peptide-immunoreactive neurons was significantly higher in the L1 and L2 dorsal root ganglia of the inflammatory group than in those of the control group, and the average cross-sectional area of the cells from L1-L5 dorsal root ganglion increased. Associated with the inflammation in the facet joints, the change in calcitonin gene-related peptide-immunoreactive neuron distribution and the phenotypic switch to large neurons may complicate the mechanism of facet joint inflammatory pain.
A Computationally Efficient QR-Successive Interference Cancellation Scheme for Simplified Receiver Implementation in SFBC-OFDM Systems (2007)

In this paper, we propose a computationally efficient square-root and division free recursive QR (SDRQR) decomposition based successive interference cancellation (SIC) receiver for space-frequency block coded orthogonal frequency division multiplexing (SFBC-OFDM) transmit diversity schemes. The performance of the proposed SDRQR-SIC receiver is semi- analytically evaluated taking into account the effects of channel estimation errors and error propagation during SIC. In addition, performance and complexity comparisons are drawn with previously proposed approaches. These comparisons show an excellent performance-complexity tradeoff achieved by SDRQR-SIC over the previous solutions under various channel conditions.
Aminoglutethimide without hydrocortisone in the treatment of postmenopausal patients with advanced breast cancer. (1986)

In a phase II study, 38 evaluable patients with advanced progressive breast cancer were treated with 4 X 250 mg of aminoglutethimide per day without hydrocortisone supplementation. Partial remissions were observed in five patients (13%), with a median duration of 9 months (range, 7-15), and stable disease was observed in 17 patients (45%), with a median duration of 4 months (range, 2-11). The recorded side effects (CNS, cutaneous, gastrointestinal) were tolerable and transient and required drug discontinuation in only four patients. Serial determinations of serum hormone levels during aminoglutethimide treatment revealed a significant decrease in estradiol and an increase in gonadotropins, testosterone, and progesterone. No patients had adrenal insufficiency. In contrast, despite prolonged aminoglutethimide treatment and persisting hypoestrogenemia, both cortisol levels and adrenal responses to ACTH remained unaltered. It is concluded that aminoglutethimide alone is effective in the treatment of postmenopausal patients with breast cancer. Moreover, based on the present findings, a prospective randomized study is warranted to show that hydrocortisone supplementation appears to not be mandatory, either for increase in efficacy or for decrease in side effects of the treatment.
Immunoregulatory functions of cultured human T lymphocytes. (1980)

Twenty continuous cultures of human T cells (CTC) (15 from normal individuals and five from patients with T cell malignancy) growing in the presence of PHA-stimulated lymphocyte conditioned medium were studied for their ability to participate in the regulation of the in vitro immunoglobulin (Ig) production induced by five polyclonal activators, pokeweed mitogen (PWM), Epstein-Barr virus (EBV), Nocardia opaca water-soluble mitogen (NWSM), streptolysin O (SLO), and staphylococcl phage lysate (SPL). The CTC did not produce significant amounts of Ig in the presence of any polyclonal activator. One out of 15 CTC examined showed helper activity of moderate degree when co-cultured with B cells rigorously depleted of T cells in PWM-driven Ig biosynthesis. Two of the other CTC helped minimally. Nine of 20 CTC examined (8 of 15 from normal individuals and 1 of 5 from patients with T cell malignancies) were found to have marked suppressor cell activity when co-cultured with normal lymphocytes in the PWM-induced Ig production system and four had moderate or variable suppressive effect. This suppression was apparently not due to simple "overgrowth" or nonspecific toxic effects of CTC because (1) the CTC did not proliferate when cultured without conditioned medium, (2) the CTC did not suppress Ig production when they were added 3 days after the beginning of the 12-day cultures, (3) the CTC did not show cytotoxic activity against normal T and B cells, and (4) the CTC did not inhibit tritiated thymidine incorporation into PWM- or EBV-stimulated lymphocytes when mixed with them at the onset of culture. Ig production induced by EBV or NWSM, which are relatively T cell-independent polyclonal activators, was suppressed significantly T cell-independent polyclonal activators, was suppressed significantly by only one out of nine and one out of six CTC examined, respectively. Four clones produced by a limiting dilution method from one suppressor CTC suppressed PWM-driven Ig synthesis as markedly as the uncloned suppressor CTC. Such CTC may be of considerable value in studies of the mechanisms involved in the regulation of immunoglobulin biosynthesis and in the preparation of antisera to T cell subsets.
Induction of apoptosis by primary HIV-1 isolates correlates with productive infection in peripheral blood mononuclear cells (1997)

These results show that apoptosis induction in PBMC by primary HIV-1 isolates is closely related to the kinetics of virus replication but is not influenced by other biological properties of the virus such as syncytium-inducing capacity and MT-2 tropism.
Verification of asynchronous circuits by Petri net unfoldings (2002)

In this paper we use the interpreted Petri nets (signal transition graph (STG) model) for a verification of asynchronous circuits. The main property in the analysis is the speed-independence of a circuit, i.e. the independence of circuit functioning from the delays of gates. The idea of analysis is based on the PN unfolding into an occurrence net. The improved method of unfolding is suggested, in which the size of the obtained description is always not larger than the size of a corresponding state graph. In terms of unfolding, the necessary and sufficient conditions for speed-independence are formulated. The algorithms of these conditions analysis are polynomial from the size of STG unfolding. The efficiency of the suggested algorithms is considered on the set of benchmarks.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

L-homoarginine appears to be increased during the second and third trimesters of pregnancy and may contribute to the enhanced endothelial function in normal pregnancies.
Improving low-light CMOS performance with four-transistor four-shared pixel architecture and charge-domain binning (2006)

A new architecture found in the KODAK KAC-3100 CMOS Image Sensor has been created to dramatically improve CMOS image performance in mobile applications. The method of operation and implementation is explained and the improvement of performance parameters on image quality is discussed. The benefits of the new architecture are discussed in relation to competitive CMOS technologies used in high-demanding mobile imaging applications today.
Asymmetry phenomenon of log-periodic dipole antennas (1976)

The existence of asymmetric resonant modes on standard log-periodic dipole antennas is established experimentally. These modes are characterized by sharply-resonant side radiation sometimes accompanied by reduction in front-lobe gain. The resonances occur at frequencies whose relationship is approximately log-periodic. In a single antenna the resonant modes are excited by any structural asymmetry, while in an <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E</tex> -plane array each individual antenna excites the others asymmetrically. The resonances can be eliminated by the addition of lossy material to appropriate parts of the antenna. Qualitatively the phenomenon is explained in terms of transmission-line resonances along the two-wire lines formed by adjacent dipoles. Automated swept-frequency far-field measurement techniques were employed throughout, and their worth is clearly established for broadband antenna research and development.
An Extensible Framework for Verification of Numerical Claims (2017)

In this paper we present our automated fact checking system demonstration which we developed in order to participate in the Fast and Furious Fact Check challenge. We focused on simple numerical claims such as "population of Germany in 2015 was 80 million" which comprised a quarter of the test instances in the challenge, achieving 68% accuracy. Our system extends previous work on semantic parsing and claim identification to handle temporal expressions and knowledge bases consisting of multiple tables, while relying solely on automatically generated training data. We demonstrate the extensible nature of our system by evaluating it on relations used in previous work. We make our system publicly available so that it can be used and extended by the community. 1 1 https://github.com/sheffieldnlp/ numerical-fact-checking-eacl2017
Enhancing MPEG-4 CELP by jointly optimized inter/intra-frame LSP predictors (2002)

This paper presents an LSP quantization design method for bandwidth scalable coders such as the MPEG-4 CELP coder. In the enhancement layer of these coders, the LSP parameters are quantized using both interframe and intraframe predictors. The proposed design algorithm enables us to jointly optimize these predictors. Objective and subjective test results show that the quantizer obtained with the proposed algorithm provides better performance than that used in the MPEG-4 CELP.
Transformation and Densification of Nanocrystalline θ‐Alumina during Sinter Forging (1996)

The sinter forging behavior of α‐Al 2 O 3 seeded and unseeded nanocrystalline θ‐Al 2 O 3 was investigated as a function of temperature, stress, and strain rate. Seeded samples exhibited the highest degree of plastic deformation during the θ‐ to α‐AI 2 O 3 phase transformation. As a result, microstructure control, increased densification, and a higher degree of transformation were obtained. A uniform microstructure of 150 nm α‐Al 2 O 3 grains developed, reaching 57% relative density after sintering 1.5 wt%α‐Al 2 O 3 seeded samples for 30 min at 1060°C. When sinter forged at 0.25 mm/min to 63 MPa and 1060°C for 30 min large deformations during the phase transformation increased the relative density to 74%. When the stress was increased to 235 MPa (1060°C, 30 min), 99.7% dense α‐Al 2 O 3 with a grain size of 230 nm was obtained. By increasing the sinter forging temperature to 1150°C, 99.5% relative density was achieved at 190 MPa for 30 min.
Genetically Encoded 1,2-Aminothiols Facilitate Rapid and Site-Specific Protein Labeling via a Bio-orthogonal Cyanobenzothiazole Condensation (2011)

We report evolved orthogonal pyrrolysyl-tRNA synthetase/tRNA(CUA) pairs that direct the efficient, site-specific incorporation of N(ε)-L-thiaprolyl-L-lysine, N(ε)-D-cysteinyl-L-lysine, and N(ε)-L-cysteinyl-L-lysine into recombinant proteins in Escherichia coli . We demonstrate that the unique 1,2-aminothiol introduced by our approach can be efficiently, rapidly, and specifically labeled via a cyanobenzothiazole condensation to quantitatively introduce biophysical probes into proteins. Moreover, we show that, in combination with cysteine labeling, this approach allows the dual labeling of proteins with distinct probes at two distinct, genetically defined sites.
The design and comparison of elliptic filters with an OTA-C structure (2002)

A CMOS operational transconductance amplifier and capacitor (OTA=C) integrator which is used for high-frequency operation has been designed and simulated by the SPICE 2G program. The authors have realized the continuous-time OTA=C elliptic low-pass filters by a cascade method and a signal flow graph (SFG) method using only capacitors and OTAs. The frequency characteristics of the OTA=C filters are compared.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Formation of ion-irradiation-induced atomic-scale defects on walls of carbon nanotubes (2001)

Recent experiments on irradiated carbon nanotubes provide evidence that ion bombardment gives rise to nanotube amorphization and dramatic dimensional changes. Using an empirical potential along with molecular dynamics, we study structure and formation probabilities of atomic-scale defects produced by low-dose irradiation of nanotubes with Ar ions. For this, we simulate impact events over a wide energy range of incident ions. We show that the maximum damage production occurs for a bombarding ion energy of about 600 eV, and that the most common defects produced at all energies are vacancies, which at low temperatures are metastable but long-lived defects. Employing the tight-binding Green's function technique, we also calculate scanning tunneling microscopy (STM) images of irradiated nanotubes. We demonstrate that irradiation-induced defects may be detected by STM and that isolated vacancies may look like bright spots in atomically resolved STM images of irradiated nanotubes.
Scalable Concatenative Speech Synthesis Based on the Plural Unit Selection and Fusion Method (2006)

Recently, concatenative speech synthesizers with large databases have been widely developed for high-quality speech synthesis. However, some platforms require a speech synthesis system that can work under the limitation of memory footprint or computational cost. In this paper, we propose a scalable concatenative speech synthesizer based on the plural speech unit selection and fusion method. To realize scalability, we propose the offline unit fusion method in which pitch-cycle waveforms for voiced segments are fused in advance. The experimental results show that the synthetic speech of the offline unit fusion method with half-size waveform database is comparable to that of the online unit fusion method, while the computation cost is reduced to 1/10.
Wideband Lithium Niobate FBAR Filters (2013)

Filters based on film bulk acoustic resonators (FBARs) are widely used for mobile phone applications, but they can also address wideband aerospace requirements. These devices need high electromechanical coupling coefficients to achieve large band pass filters. The piezoelectric material LiNbO 3 complies with such specifications and is compatible with standard fabrication processes. In this work, simple metal—LiNbO 3 —metal structures have been developed to fabricate single FBAR elements directly connected to each other on a single chip. A fabrication process based on LiNbO 3 /silicon Au-Au bonding and LiNbO 3 lapping/polishing has been developed and is proposed in this paper. Electrical measurements of these FBAR filters are proposed and commented exhibiting filters with 8% of fractional bandwidth and 3.3 dB of insertion losses. Electrical measurements show possibilities to obtain 14% of fractional bandwidth. These devices have been packaged, allowing for power handling, thermal, and ferroelectric tests, corresponding to spatial conditions.

Quinazoline Derivatives as Green Corrosion Inhibitors for Carbon Steel in Hydrochloric Acid Solutions (2013)

The inhibiting effect of some quinazoline derivatives on the corrosion of carbon steel in 2 M HCl was studied by weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) and energy dispersion spectroscopy (EDS) techniques. The results showed that the inhibition efficiency increases with increasing the inhibitor concentration, while it decreases with increasing the temperature. The adsorption of quinazoline derivatives on the carbon steel surface obeys Temkin adsorption isotherm. Some thermodynamic parameters were calculated and discussed. Polarization curves show that quinazoline derivatives are mixed-type inhibitors but the cathode is more polarized than the anode. The results obtained from chemical and electrochemical techniques are in good agreement.
Probabilistic leak detection in pipelines using the mass imbalance approach (2005)

Typically, models of pipelines and pipe networks are calibrated to metered data by optimizing the choice of parameters according to some penalty function. This approach does not provide a natural way to assess the predictive uncertainty when these models are used to infer the presence and description of a leak. This paper describes a fully probabilistic approach in which the activities of calibration and prediction are unified, using the massimbalance approach to leak detection as an example. The resulting probability distribution over leak location and size can be presented graphically, or it can be used within an optimal decision framework to compute an effective response taking uncertainty into account. The approach is generalized to different leak-scenarios, which could include multiple leaks.
Forced Expression of HoxB4 Enhances Hematopoietic Differentiation by Human Embryonic Stem Cells (2008)

HoxB4 has been shown to enhance hematopoietic engraftment by hematopoietic stem cells (HSC) from differentiating mouse embryonic stem cell (mESC) cultures. Here we examined the effect of ectopic expression of HoxB4 in differentiated human embryonic stem cells (hESCs). Stable HoxB4-expressing hESCs were established by lentiviral transduction, and the forced expression of HoxB4 did not affect stem cell features. HoxB4-expressing hESC-derived CD34+ cells generated higher numbers of erythroid and blast-like colonies than controls. The number of CD34+ cells increased but CD45+ and KDR+ cell numbers were not significantly affected. When the hESC derived CD34+ cells were transplanted into NOD/SCID beta 2m-/- mice, the ectopic expression of HoxB4 did not alter their repopulating capacity. Our findings show that overexpression of HoxB4 in differentiating hESCs increases hematopoietic colony formation and hematopoietic cell formation in vitro, but does not affect in vivo repopulation in adult mice hosts.

In vitro inhibition of aggregation of human erythrocytes by synthetic fibrinolytic compounds. (1975)

It has been shown that a variety of synthetic organic anions which induce fibrinolytic activity in human plasma in vitro and which in addition inhibit collagen-induced aggregation of human platelets, also exert to various degrees an inhibition of dextran, fibrinogen and gelatin induced aggregation of human erythrocytes and of the pathologically accelerated erythrocyte sedimentation rate. Since increased erythrocyte aggregation is contributing to thrombogenesis, ability to prevent erythrocyte aggregation is a desirable feature for synthetic antithrombotic compounds. They should exert three actions: induce fibrinolytic activity, prevent platelet aggregation, and inhibit erythrocyte aggregation. This communication refers to prototypes of such compounds.
