Interactions among plant hormones, carbon dioxide, and light in the relief of thermoinhibition of lettuce seed germination: studies in a flow-through gaseous system (1986)

The effects of gibberellin A 3 (GA 3 ), kinetin, C 2 H 4 , CO 2 , and (or) red light (5-min single exposure) on the germination of lettuce (Lactuca sativa L. cv. Grand Rapids) seeds at 32 °C were studied in a continuous-flow system. This system permitted strict control of the gaseous environment, which has not been possible in previous experimental set-ups. Except for a minor effect of light (10% enhancement), none of the treatments applied singly had any effect on the germination of these thermo-inhibited seeds. The action of any one hormone (GA 3 , kinetin, C 2 H 4 ) required the presence of at least one more hormone or CO 2 or light. Complete alleviation of thermoinhibition required a minimum of three factors in the following combinations: GA 3 with two of kinetin, C 2 H 4 , or CO 2 , and kinetin either with GA 3 + light or C 2 H 4 + light. Given in combination with light, kinetin, GA 3 + C 2 H 4 , GA 3 + CO 2 , or C 2 H 4 + CO 2 induced above 75% germination. Approximately half maximal germination was obtained with GA 3 + kinetin, GA 3 + CO 2 , and C 2 H 4 + light. Other treatment combinations showed either no or only a weak interaction. Results showed that the action of hormones, particularly that of GA 3 , was markedly influenced by CO 2 . Carbon dioxide was also able to substitute for a number of other treatments that interacted with GA 3 . In addition, the effects of several interactive treatments were further accentuated by CO 2 .
Efficacy and Tolerability of Paroxetine for the Long-Term Treatment of Generalized Anxiety Disorder (2003)

Paroxetine was found to be effective and well tolerated for both the short- and long-term treatment of DSM-IV GAD. Continued treatment with paroxetine significantly reduced the potential for relapse of GAD symptoms.
Antiviral Activity of Lovastatin against Respiratory Syncytial Virus In Vivo and In Vitro (2001)

Respiratory syncytial virus (RSV) is an important human pathogen that can cause severe and life-threatening respiratory infections in infants and immunocompromised adults. We have recently shown that the RSV F glycoprotein, which mediates viral fusion, binds to RhoA. One of the steps in RhoA activation involves isoprenylation at the carboxy terminus of the protein by geranylgeranyltransferase. This modification allows RhoA to be attached to phosphatidyl serine on the inner leaflet of the plasma membrane. Treatment of mice with lovastatin, a drug that inhibits prenylation pathways in the cell by directly inhibiting hydroxymethylglutaryl coenzyme A reductase, diminishes RSV but not vaccinia virus replication when administered up to 24 h after RSV infection and decreases virus-induced weight loss and illness in mice. The inhibition of replication is not likely due to the inhibition of cholesterol biosynthesis, since gemfibrozil, another cholesterol-lowering agent, did not affect virus replication and serum cholesterol levels were not significantly lowered by lovastatin within the time frame of the experiment. Lovastatin also reduces cell-to-cell fusion in cell culture and eliminates RSV replication in HEp-2 cells. These data indicate that lovastatin, more specific isoprenylation inhibitors, or other pharmacological approaches for preventing RhoA membrane localization should be considered for evaluation as a preventive antiviral therapy for selected groups of patients at high risk for severe RSV disease, such as the institutionalized elderly and bone marrow or lung transplant recipients.

Subsea Multiphase Boosting - Maturing technology Applied for Santos Ltd's Mutineer and Exeter field (2004)

Abstract The paper presents the state of art in subsea multiphase boosting. This includes the subsea pump, subsea integration, power and control system, umbilical, and intervention. Further, the typical applications and characteristics for subsea multiphase boosting systems will be addressed. The benefits to the users are normally related to reduced investments and even more important, increased and/or accelerated oil production. There are also several examples of subsea multiphase pumps as production enabling equipment. Typical reference projects and field experience will also be presented. Although multiphase pumps in most cases are used as independent systems there may be a significant potential in combining this solution with other artificial lift technologies. They may be used in combination with gas lift or downhole pumps to offer integrated systems with premium reliability and economics. The second part of the presentation will be related specifically to the subsea multiphase pump system recently selected for Santos LTd's Mutineer and Exeter field offshore NW Australia. The overall subsea system architecture will be presented with particular focus on the subsea multiphase pump system. Considerations, advantages and expectations to this solution as seen by the operator, will be addressed.
Posterolateral Corner of the Knee: Current Concepts. (2016)

Injuries to the posterolateral corner (PLC) comprise a significant portion of knee ligament injuries. A high index of suspicion is necessary when evaluating the injured knee to detect these sometimes occult injuries. Moreover, a thorough physical examination and a comprehensive review of radiographic studies are necessary to identify these injuries. In this sense, stress radiographs can help to objectively determine the extent of these lesions. Non-operative and operative treatment options have been reported depending on the extent of the injury. Complete PLC lesions rarely heal with non-operative treatment, and are therefore most often treated surgically. The purpose of this article was to review the anatomy and clinically relevant biomechanics, diagnosis algorithms, treatment and rehabilitation protocols for PLC injuries.
Mechanism by Which Mammalian Target of Rapamycin Inhibitors Sensitize Multiple Myeloma Cells to Dexamethasone-Induced Apoptosis (2006)

Mammalian target of rapamycin (mTOR) inhibitors curtail cap-dependent translation. However, they can also induce post-translational modifications of proteins. We assessed both effects to understand the mechanism by which mTOR inhibitors like rapamycin sensitize multiple myeloma cells to dexamethasone-induced apoptosis. Sensitization was achieved in multiple myeloma cells irrespective of their PTEN or p53 status, enhanced by activation of AKT, and associated with stimulation of both intrinsic and extrinsic pathways of apoptosis. The sensitizing effect was not due to post-translational modifications of the RAFTK kinase, Jun kinase, p38 mitogen-activated protein kinase, or BAD. Sensitization was also not associated with a rapamycin-mediated increase in glucocorticoid receptor reporter expression. However, when cap-dependent translation was prevented by transfection with a mutant 4E-BP1 construct, which is resistant to mTOR-induced phosphorylation, cells responded to dexamethasone with enhanced apoptosis, mirroring the effect of coexposure to rapamycin. Thus, sensitization is mediated by inhibition of cap-dependent translation. A high-throughput screening for translational efficiency identified several antiapoptotic proteins whose translation was inhibited by rapamycin. Immunoblot assay confirmed rapamycin-induced down-regulated expressions of XIAP, CIAP1, HSP-27, and BAG-3, which may play a role in the sensitization to apoptosis. Studies in a xenograft model showed synergistic in vivo antimyeloma effects when dexamethasone was combined with the mTOR inhibitor CCI-779. Synergistic effects were associated with an enhanced multiple myeloma cell apoptosis in vivo. This study supports the strategy of combining dexamethasone with mTOR inhibitors in multiple myeloma and identifies a mechanism by which the synergistic effect is achieved.
High-quality scanning using time-of-flight depth superresolution (2008)

Time-of-flight (TOF) cameras robustly provide depth data of real world scenes at video frame rates. Unfortunately, currently available camera models provide rather low X-Y resolution. Also, their depth measurements are starkly influenced by random and systematic errors which renders them inappropriate for high-quality 3D scanning. In this paper we show that ideas from traditional color image superresolution can be applied to TOF cameras in order to obtain 3D data of higher X-Y resolution and less noise. We will also show that our approach, which works using depth images only, bears many advantages over alternative depth upsampling methods that combine information from separate high-resolution color and low-resolution depth data.
Incorporating Heterogeneous Redundancy in a Nanoprocessor for Improved Yield and Performance (2010)

Emerging nano-device based architectures are expected to experience high defect rates associated with the manufacturing process. In this paper, we introduce a novel built-in heterogeneous fault-tolerance scheme, which incorporates redundant circuitry into the design to provide fault tolerance. A thorough analysis of the new scheme was carried out for various system level metrics. The implementation and analysis were carried out on WISP-0, a stream processor implemented on the Nanoscale Application Specific Integrated Circuits (NASIC) fabric. We show that intelligent assignment of redundancy levels and nanoscale-voting strategies across WISP-0 greatly improves area, effective yield and performance for the nano-processor. The new scheme outperforms homogeneous schemes for a defect range of 3% to 9.75% where the metric used is the product of performance and effective yield.
Synthesis of biologically active molecules by imprinting polymerisation (2006)

Highly cross-linked molecularly imprinted polymers (MIPs) are synthetic materials with properties mimicking those of natural receptors. Here we describe an ability of nanoparticles to manifest biological activity. Molecularly imprinted polymers were synthesised by co-polymerisation of urocanic acid, N,N'-bisacryloyl piperazine in the presence of herbicide binding Dl protein, ground and separated from the template by washing and ultrafiltration. It was demonstrated that nanoparticles retained affinity to the template. Moreover, imprinted polymers were able to activate chloroplast photosystem II in in vitro experiments. This provides the first example of the use of imprinted polymers for the attenuation of a biological system and opens new possibilities for their application in pharmacology, biotechnology and medicine.
Performance analysis of radio propagation models for Smart Grid applications (2011)

Realizing future Smart Grid applications highly depend on the communication technologies being used. For this purpose, an ubiquitous communication infrastructure is essential, providing real time communication and reliable connectivity to Smart Grid components. Especially nowadays wireless radio networks offer a cost-efficient, reliable and well-engineered solution. In this paper we present a performance analysis based on a comparison of analytic channel models and Ray Tracing simulations for wireless digital cellular networks with respect to actual Smart Grid deployment scenarios. Both methods are applied especially under consideration of a typical outdoor-to-indoor transition models. Based upon these results a coverage analysis for wireless digital cellular networks (e.g. GSM or UMTS) is shown considering different Smart Metering and energy management application scenarios including position-based radio characteristics, like basement, indoor and outdoor installations. The network topology is described using a simulation environment including various analytic models in order to analyze the capacity of the transmission technology in real-world scenarios. Our analysis shows the impact on the path loss, caused by frequencies, geographical position and indoor deployment, which leads to an additional deviation up to 25 dB.
Thermodynamic Characterization in CO2 Plasma Jet Produced by VKI Plasmatron Facility (2011)

The radiation of the CO2 plasma jet produced by the VKI-Plasmatron high enthalpy wind tunnel is investigated by means of Optical Emission Spectroscopy (OES) diagnostic in the visible spectral range. Radial thermodynamic state characterization was conducted at 200 mbar operating pressure using absolute measurements of O and C atomic lines and emission of vibrational bands of C2 Swan system. Approaches based on Local Thermodynamic Equilibrium (LTE) assumption as well on thermal equilibrium and chemical non equilibrium have been adopted. The good agreement on temperature profiles derived from di fferent methods allows to assert the thermal equilibrium of the plasma. Measured temperature at the center of the jet was found to be about 6500 K. The line of sight intensity, due to C2 Swan and CO 4th Positive emission, have been rebuilt using averaged temperature profiles resulting from optical diagnostic performed on atomic lines, and are critically compared with experimental data.
Tactile Accessibility (2016)

Graphical user interfaces (GUIs) are widely used on smartphones, tablets, and laptops. While GUIs are convenient for sighted users, their accessibility for blind people, who use screen readers to interact with GUIs, remains to be problematic. Even the most screen-reader accessible GUIs are far less usable for blind people compared to sighted people, because the former group cannot benefit from the geometric layout of GUIs. As a result, blind people often have to listen through a lot of irrelevant content before they find what they are looking for. Haptic interfaces (those providing tactile feedback) have the potential to make GUI interfaces more accessible and usable for blind people. Alas, mainstream computer devices do not have haptic screens that would enable high-resolution tactile feedback, and specialized haptic devices are very limited and/or are exuberantly expensive and bulky.
Negative Affect and Smoking Lapses: A Prospective Analysis. (2004)

Relapse is a central problem in smoking treatment. Data collected at the time of relapse episodes indicate that stress and negative affect (NA) promote relapse, but retrospective data are potentially biased. The authors performed a prospective analysis of stress and NA prior to initial lapses in smokers (N = 215). Day-to-day changes in stress (daily negative and positive events and Perceived Stress Scale scores) and NA (multiple momentary affect ratings) did not predict lapse risk on the following day. However, within the lapse day itself, NA was already significantly increasing hours before lapses, but only for episodes attributed to stress or bad mood. Thus, rapid increases in NA, but not slow-changing shifts in stress and NA, were associated with relapse.
Probabilistic scheme for laser based motion detection (2008)

This paper presents a motion detection scheme using laser scanners mounted on a mobile vehicle. We propose a stable, yet simple motion detection scheme that can be used and improved with tracking and classification procedures. The salient contribution of the developed architecture is twofold. It proposes a spatio-temporal correspondence procedure based on a scan registration algorithm. The detection is cast as a probability decision problem that accounts for sensor noise and achieves robust classification. Probabilistic occlusion checking is finally performed to improve robustness. Experimental results show the performance of the proposed architecture under different settings in urban environments.
Attacking the IV Setup of Stream Cipher LEX (2005)

In this paper, we point out that the initialization of stream cipher LEX is weak. If a key is used with about 2 random IVs, and 20,000 keystream bytes are generated from each IV, then the key could be recovered easily.
Geographical differences in the UV Measured by intercompared spectroradiometers (1995)

Five UV spectroradiometers representative of the types used in monitoring programs on several continents were intercompared at the Fraunhofer Institute for Atmospheric Environmental Research (IFU), Garmisch‐Partenkirchen, Southern Germany, during a campaign in August 1994. Global spectral irradiances between 290 and 410 nm were measured over a range of solar zenith angles from 30° to 80°. Scans were synchronized to enable useful comparisons to be made under changing weather conditions, which included overcast, partly cloudy, and clear skies. No exchange of data was allowed between participating groups until after the campaign. At wavelengths longer than 310 nm, the spectra generally agreed to within ±5%. At wavelengths shorter than 310 nm, differences between instruments were larger, especially at larger solar zenith angles. Causes of differences are discussed. For all instruments, deviations in erythemally weighted irradiances were always less than 7% from the mean. The agreement between measurement systems is sufficient to allow an investigation of geographical differences in UV, under all observing conditions. UV doses measured at sites in the southern hemisphere are systematically larger than those measured at the corresponding northern latitudes. During the summer months the daily doses at the South Pole exceed those at mid‐latitudes in the Northern Hemisphere. Further investigations must be performed to establish a global UV‐climatology.
Diphenylhydantoin (dilantin) gingival hyperplasia: drug-induced abnormality of connective tissue. (1976)

Various degrees of gingival overgrowth may occur in individuals taking diphenylhydantoin, a drug used widely in the treatment of epilepsy. The tissue overgrowth is made up predominantly of collagen, and may therefore be a useful model for analysis of fibrosis and some other connective tissue abnormalities. Fibroblasts derived from the overgrown tissue exhibit a level of protein synthetic activity approximately twice that of comparable cells obtained from nonepileptic control individuals and from the gingiva of age-matched epileptics taking the drug but not exhibiting gingival enlargement. In addition, 20% of the protein synthesized by cells from the affected tissue is collagen, whereas collagen accounts for only about 11% of the total protein produced by control cells of both types. The drug appears to induce or select for fibroblasts characterized by enhanced levels of protein synthesis and collagen production. This alteration persists through several cell replications in vitro in the absence of drug.

Optimization of fiber-based spectral domain optical coherence tomography system (2010)

The hardware parameters of a spectral domain OCT (SD-OCT) system are analyzed for the optimal OCT imaging. These parameters include pixel number and digitization depth of the line CCD in the spectrometer,and the tolerance of CCD installation. Calibration of the spectrum localization is carried out. The depth resolution is not affected by the CCD linear array pixel number,but with the increasing of CCD linear array pixel number,the maximum probing depth increases linearly. If the digitization depth of CCD is higher than 6bit,it is possible to calculate useful depth cans with good resolutions. When the CCD is moved several millimeters away from the focal plane,the value of point spread function (PSF) will decrease,and the resolution will degrade. When the CCD rotates several degree,full width at half maximum (FWHM) of the PSF will decrease,denoting the increasing of the axial resolution. After calibration using Ne lamp spectrum,the quality of the image will be obviously improved. Some of the results are experimentally verified. For SD-OCT system,the optimal system parameters can be selected for specific application.
