An uplink antenna for electronic beam steering and interference reduction (2003)

High data rate satellite communication systems require satellite antennas with high gain to obtain link closure. These narrow beamwidth antennas can suffer performance loss because of antenna pointing errors. Interference susceptibility is also a concern and a means of reducing interference is desired. An uplink antenna system concept is described for such requirements.
CO2-Foam Rheology Behavior under Reservoir Conditions (2017)

Abstract Super critical carbon dioxide (SC-CO2) flooding is one of the most important enhanced oil recovery (EOR) methods to recover oil from both sandstone and carbonate reservoirs. In many cases this process is handicapped, especially in thick reservoirs, by SC-CO2 gravity override. SC-CO2 is lighter than oil and water, so there can be extensive gravity override of SC-CO2 bypassing oil in the lower part of the formation. Different methods have been used to control SC-CO2 mobility and improve its sweep efficiency by either increasing its density, viscosity, or reducing its relative permeability. SC-CO2 as a foam or as an emulsion is one of these methods and can provide better mobility control of the injected SC-CO2. This paper investigates the impact of various parameters such as liquid/liquid ratio, different foam qualities and different injection modes on the SC-CO2-foam quality and its rheological properties. In this study, types of surfactants were used to generate SC-CO2-foam. SC-CO2-foam was generated at two different type of injection modes. Experiments were designed and conducted in a high pressure and temperature flow loop instrument to identify the optimum surfactant concentration and liquid/liquid ratio that can produce high quality foam and increase the SC-CO2 viscosity. During the experiment, SC-CO2-foam characteristics were analyzed through a visual cell in terms of bubble size distribution. The rheological properties of the SC-CO2-foam were investigated by varying the shear rate, shear stress, foam quality, injection modes and foaming agent concentrations at reservoir conditions. The experimental results show that the foam mobility (total mobility of SC-CO2-surfactant solution) decreases with increasing foam quality. The results indicate that the SC-CO2-foam can make strong and stable foams under certain conditions. This was also correlated with the images of the high pressure, high temperature (HPHT) foams that were captured through microscope at different time intervals and analyzed to indicate their stability. Two foaming agents were identified that show excellent foam quality with good foam strength and stability over a period of time at reservoir conditions.
REBCO Layer-Wound Coil Tests Under Electromagnetic Forces in an External Magnetic Field of up to 17.2 T (2012)

A nuclear magnetic resonance (NMR) system using a high-temperature superconducting (HTS) magnet and a probe with an HTS radio frequency coil is currently under development. The HTS NMR magnet is expected to reduce the volume occupied by the magnet and to encourage users to install higher field NMR systems. RE-Ba-Cu-O-coated (REBCO-coated) conductors offer the advantages of a higher critical current density than low-temperature superconductors in magnetic fields above 10 T as well as tolerance to high tensile stress. Both of these factors are expected to lead to a reduction in the volume of the magnet. Four REBCO layer-wound test coils were fabricated in order to investigate their properties under electromagnetic forces in an external magnetic field of up to 17. 2 T. The REBCO coils with a practical inner diameter were successfully operated under electromagnetic forces of over 200 MPa in high magnetic fields.
Loss-load curves (1991)

Congestion control is an important problem in high-speed computer networks. Networks must limit the packet load that they accept to avoid excessive packet loss and delay. Hosts must limit their transmission rates to match what the network can handle at any given time or else suffer high packet drop rates. Rate-based congestion control schemes control network load by regulating the rate of packet transmission into the network.
Convergent Results from Experimental and Theoretical DFT Studies of the Intramolecular Rearrangement of <i>Z-</i>Hydrazones of 3-Acyl-1,2,4-Oxadiazoles (2004)

A combined kinetic and theoretical study of the monocyclic rearrangements of heterocycles (MRH) has been carried out. The interconversion of the Z-hydrazone of 3-benzoyl-5-phenyl-1,2,4-oxadiazole into the corresponding triazole has been experimentally investigated in dioxane/water in the pS+ range 5.55−13.9. The uncatalyzed region has been examined at the DFT level using a model system formed by the Z-hydrazone of 3-formyl-1,2,4-oxadiazole and one or two water molecules. The environmental effect of the solvent has been emulated using a continuum model (COSMO) approach. The kinetic data suggest a concerted process where the magnitude of the activation barrier is determined by the interplay of two opposite factors, that is, the nucleophilicity of the nitrogen atom and the acidity of the nitrogen-bonded protons. The computations indicate the existence of two multistep reaction pathways. When the solvent environment is taken into account, the preferred path, which involves two water molecules acting as a base, becomes a concerted highly asynchronous path, where the nucleophilic attack and the proton transfer occur not simultaneously but in the same kinetic step.
[Variability of the arteries of the nose]. (1985)

Arriving current, width and course of the arteries of the outer nose were investigated at 40 headhalves. We defined 4 groups of vessel patterns. Also 6 types of variations were described and right-left-differences were determined. The results are discussed in detail with the dates of former scientists.
Fibroblast growth factor receptor 4 (FGFR4) and fibroblast growth factor 19 (FGF19) autocrine enhance breast cancer cells survival (2016)

Basal-like breast cancer is an aggressive tumor subtype with poor prognosis. The discovery of underlying mechanisms mediating tumor cell survival, and the development of novel agents to target these pathways, is a priority for patients with basal-like breast cancer. From a functional screen to identify key drivers of basal-like breast cancer cell growth, we identified fibroblast growth factor receptor 4 (FGFR4) as a potential mediator of cell survival. We found that FGFR4 mediates cancer cell survival predominantly via activation of PI3K/AKT. Importantly, a subset of basal-like breast cancer cells also secrete fibroblast growth factor 19 (FGF19), a canonical ligand specific for FGFR4. siRNA-mediated silencing of FGF19 or neutralization of extracellular FGF19 by anti-FGF19 antibody (1A6) decreases AKT phosphorylation, suppresses cancer cell growth and enhances doxorubicin sensitivity only in the FGFR4+/FGF19+ breast cancer cells. Consistently, FGFR4/FGF19 co-expression was also observed in 82 out of 287 (28.6%) primary breast tumors, and their expression is strongly associated with AKT phosphorylation, Ki-67 staining, higher tumor stage and basal-like phenotype. In summary, our results demonstrated the presence of an FGFR4/FGF19 autocrine signaling that mediates the survival of a subset of basal-like breast cancer cells and suggest that inactivation of this autocrine loop may potentially serve as a novel therapeutic intervention for future treatment of breast cancers.
DA-RNN: Semantic Mapping with Data Associated Recurrent Neural Networks (2017)

3D scene understanding is important for robots to interact with the 3D world in a meaningful way. Most previous works on 3D scene understanding focus on recognizing geometrical or semantic properties of the scene independently. In this work, we introduce Data Associated Recurrent Neural Networks (DA-RNNs), a novel framework for joint 3D scene mapping and semantic labeling. DA-RNNs use a new recurrent neural network architecture for semantic labeling on RGB-D videos. The output of the network is integrated with mapping techniques such as KinectFusion in order to inject semantic information into the reconstructed 3D scene. Experiments conducted on a real world dataset and a synthetic dataset with RGB-D videos demonstrate the ability of our method in semantic 3D scene mapping.
Optical control of microstrip stub on silicon substrate using 650 nm and 850 nm wavelengths illumination (2008)

In this paper we have studied the optical control of transmission behaviour of lambdag/4 microstrip stub on a microstrip line fabricated on high resistivity silicon substrate by illuminating open end of lambdag/4 stub. Here, we have used two different optical wavelength sources 650 nm and 850 nm to illuminate the open end of stub. An optical illumination at the end of an open lambdag/4 stub on a microstrip line has been shown to control the transmitted power at the design frequency which can be used as an optically controlled rf switching or attenuator and further can be used as an optically controlled narrow band matching and stub based filters. In addition to experimental measurement we have also carried out modelling of optically generated load at the end for both the wavelengths along with the simulation on Ansoft Maxwell simulator. The measurement results compare well with those predicted by a simulation carried out on the Ansoft Maxwell Ensemble for both the wavelengths.
Learning convolutional neural networks from few samples (2013)

Learning Convolutional Neural Networks (CNN) is commonly carried out by plain supervised gradient descent. With sufficient training data, this leads to very competitive results for visual recognition tasks when starting from a random initialization. When the amount of labeled data is limited, CNNs reveal their strong dependence on large amounts of training data. However, recent results have shown that a well chosen optimization starting point can be beneficial for convergence to a good generalizing minimum. This starting point was mostly found using unsupervised feature learning techniques such as sparse coding or transfer learning from related recognition tasks. In this work, we compare these two approaches against a simple patch based initialization scheme and a random initialization of the weights. We show that pre-training helps to train CNNs from few samples and that the correct choice of the initialization scheme can push the network's performance by up to 41% compared to random initialization.

A Single-Center, Randomized, Double-Blind, Placebo-Controlled Clinical Trial of the Effectiveness of ANT1 Soybean Extract Cream on Skin Recovery After Nd (2018)

Through this study, the results suggest that the application of ANT1 soybean extract cream ameliorates the complications and enhances the cosmetic effects of Nd-YAG laser therapy. A higher concentration of the ANT1 cream significantly reduces wrinkles and redness after laser. All in all, this study proves that the ANT1 soy extract cream may be a useful addition to postlaser care for an overall enhancement in skin condition and recovery.

Some implementations of segment sequential functions (1976)

Since conventional computers are straining to handle the increased size and sophistication of non-numeric processing (data management, information retrieval, artificial intelligence), a new class of non-numeric architectures is evolving. The segment sequential architecture is one of these. Further development of this architecture requires new techniques for multiple cell operation and intercell communication to handle control and search operations. This paper describes such techniques for instruction fetching, operand recall, string, set and tree context searching, and pointer transfer. It is expected that combinations of these techniques will appear in future architectures that are needed for non-numeric processing.
Introduction (2007)

Public life is full of emotions. Understanding better how this emotionality works is an urgent challenge for the sciences and the humanities. Without such understanding, there is limited scope for comprehending patterns of public speech and action generally, or for limiting conflict. This book presents new thinking from several disciplines and traditions, to contribute to a conversation on how best to develop our understanding of public emotions.
Extreme context specificity in differential allelic expression (2007)

Variability in cis-regulation of gene expression has been implicated in the phenotypic manifestation of complex traits including common, multifactorial diseases. The differential expression of alleles due to polymorphism in cis-regulatory elements is common in the human genome, but there is a paucity of information about the context specificity of these control elements. In this study, we examined the differential allelic expression (DAE) of BMP5 in human mesenchymal tissues obtained from 16 donors undergoing joint replacement for treatment of osteoarthritis. We observed significant differences in BMP5 allelic output, with allelic ratios greater than 4:1 (P < 10(-20)) in the tissues of some donors. We also discovered a significant variability in allelic expression within the different tissues of donors. For 12 of our donors, we examined the allelic expression of BMP5 in two different regions of cartilage: cartilage adjacent to the site of the osteoarthritic lesion and cartilage distal from the lesion. Five of these 12 donors demonstrated highly significant differences (P < or = 10(-8)) in allelic expression between the different regions of their cartilage. Using DAE as a phenotype, we attempted to map tissue-specific cis-regulatory polymorphisms, and we identified a single nucleotide polymorphism located downstream of BMP5, which was significantly associated with DAE in some but not all of the examined tissues. These findings suggest that allelic expression can be highly context specific and that when interrogating the cis-regulatory control of a particular gene, one cannot necessarily assume that allelic expression is conserved across different tissues or even across different regions of the same tissue.
Expression of Rap1GAP in human myeloid disease following microarray selection (2008)

To find the underlying causes of primary myelodysplastic syndrome (MDS), the gene expression profiling of both CD34+ cells and bone marrow mononuclear cells from MDS patients was performed using oligonucleotide microarray and cDNA microarrays, respectively. Several candidate genes which were differentially expressed in MDS patients versus normal controls were selected and confirmed in expanding samples by quantitative real-time reverse transcription-polymerase chain reaction after clustering and bioinformatics analysis. one of these genes, RAP1GAP, was found to be expressed at a significantly higher level in patients with MDS in comparison with those suffering from other hematopoietic diseases including leukemia (P < 0.01). We propose that over-expression of RAP1GAP gene may play a role in the pathogenesis of MDS.
Layered view-dependent texture maps (2013)

Video-based free-viewpoint rendering from multiple view video capture has achieved video-realistic performance replay. Existing free-viewpoint rendering approaches require storage, streaming and re-sampling of multiple videos, which requires high bandwidth and computational resources limiting applications to local replay on high-performance computers. This paper introduces a layered texture representation for efficient storage and view-dependent rendering from multiple view video capture whilst maintaining the video-realism. Layered textures re-sample the captured video according to the surface visibility. Prioritisation of layers according to surface visibility allows the N-best views for all surface elements to be pre-computed significantly reducing both storage and rendering cost. Typically 3 texture map layers are required for free-viewpoint rendering with an equivalent visual quality to the multiple view video giving a significant reduction in storage cost. Quantitative evaluation demonstrates that the layered representation achieves a 90% reduction in storage cost and 50% reduction in rendering cost without loss of visual quality compared to storing only the foreground of the original multiple view video. This reduces the storage and transmission cost for free-viewpoint video rendering from eight cameras to be similar to the requirements for a single video. Streaming the layered representation enables, for the first time, demonstration of free-viewpoint video rendering on mobile devices and web platforms.
Retinyl ester synthesis by isolated adult rabbit lung type II cells. (1988)

Type II alveolar cells were isolated from adult rabbit lungs and then cultured on monolayers for 16 hours. These cells were then covered with buffered medium containing [3H]-retinol. After 30-120 minutes incubation, the cells were extracted with Hexane: Ethanol and the hexane extract analyzed by HPLC. A linear synthesis of [3H]-retinyl palmitate with time of incubation was demonstrated.
Improved motor outcome in response to magnesium therapy received up to 24 hours after traumatic diffuse axonal brain injury in rats (1999)

The present results demonstrate that Mg++ plays a neuroprotective role following severe diffuse traumatic axonal brain injury. Moreover, Mg++ therapy significantly improved motor outcome when administered up to 24 hours after injury, with early treatments providing the most significant benefit. Repeated administration beyond 24 hours postinjury did not provide additional neuroprotection.
Robust Structural Metric Learning (2013)

Metric learning algorithms produce a linear transformation of data which is optimized for a prediction task, such as nearest-neighbor classification or ranking. However, when the input data contains a large portion of noninformative features, existing methods fail to identify the relevant features, and performance degrades accordingly. In this paper, we present an efficient and robust structural metric learning algorithm which enforces group sparsity on the learned transformation, while optimizing for structured ranking output prediction. Experiments on synthetic and real datasets demonstrate that the proposed method outperforms previous methods in both high- and low-noise settings. 1.
Quantitative Analysis of Snake Venoms Using Soluble Polymer-based Isotope Labeling (2007)

We present the design and synthesis of a new quantitative strategy termed soluble polymer-based isotope labeling (SoPIL) and its application as a novel and inclusive method for the identification and relative quantification of individual proteins in complex snake venoms. The SoPIL reagent selectively captures and isolates cysteine-containing peptides, and the subsequent tagged peptides are released and analyzed using nanoflow liquid chromatography-tandem mass spectrometry. The SoPIL strategy was used to quantify venom proteins from two pairs of venomous snakes: Crotalus scutulatus scutulatus type A, C. scutulatus scutulatus type B, Crotalus oreganus helleri, and Bothrops colombiensis. The hemorrhagic, hemolytic, clotting ability, and fibrinogenolytic activities of crude venoms were measured and correlated with difference in protein abundance determined by the SoPIL analysis. The SoPIL approach could provide an efficient and widely applicable tool for quantitative proteomics.
Malaria-Infected Mice Are Cured by a Single Oral Dose of New Dimeric Trioxane Sulfones Which Are Also Selectively and Powerfully Cytotoxic to Cancer Cells (2009)

A new series of 6 dimeric trioxane sulfones has been prepared from the natural trioxane artemisinin in five or six chemical steps. One of these thermally and hydrolytically stable new chemical entities (4c) completely cured malaria-infected mice via a single oral dose of 144 mg/kg. At a much lower single oral dose of only 54 mg/kg combined with 13 mg/kg of mefloquine hydrochloride, this trioxane dimer 4c as well as its parent trioxane dimer 4b also completely cured malaria-infected mice. Both dimers 4c and 4b were potently and selectively cytotoxic toward five cancer cell lines.

Suppression of the malignant phenotype in somatic cell hybrids between Burkitt's lymphoma cells and Epstein-Barr virus-immortalized lymphoblastoid cells despite deregulated c-myc expression. (1990)

To approach the question whether the absence of specific cellular gene functions may be involved in Burkitt's lymphoma pathogenesis, somatic cell hybrids were established between a malignant Epstein-Barr virus (EBV) positive Burkitt's lymphoma cell line (BL 60) and a nonmalignant EBV-immortalized lymphoblastoid cell line (IARC 277) derived from the same individual. The hybrids revealed a near tetraploid karyotype including one copy of the 8q+ chromosome resulting from the Burkitt's lymphoma-specific translocation t(8;22) in addition to three apparently normal copies of chromosome 8. Although the hybrid cells exhibited the deregulated c-myc expression pattern of the parental Burkitt's lymphoma cell line with highly abundant transcripts originating from the 8q+ chromosome, their growth characteristics in tissue culture as well as in nude mice were identical to that of the parental nonmalignant lymphoblastoid cell line. These data indicate that, at least in the system described here, the malignant phenotype of Burkitt's lymphoma cells can be suppressed by introduction of an additional set of apparently normal chromosomes from the same individual and that EBV infection and c-myc deregulation may not be sufficient for maintenance of the malignant phenotype.
