Prediction of the spatiotemporal distribution of landslide: Integrated landslide susceptibility zoning techniques and real-time satellite rainfall (2008)

Predicting global landslide occurrences is very difficult and expensive in terms of time and money. Drawing upon recent advances of satellite remote sensing technology, an experimental landslide prediction model is developed to identify the timing for landslides induced by heavy rainfall, the primary trigger. Landslide warning systems can save lives and reduce damages if properly implemented in populated areas of landslide-prone nations. Comprehensive modeling of the physical processes involved in landslides helps pinpoint causes of landmass movement in relation to rainfall. In the future, increasing availability of improved, yet low-cost remote sensing products that can support GIS-based landslide models will likely benefit disaster prevention for landslide-prone regions. Prior to achieving that, the challenge facing the research community is to continue to develop techniques to better understand landslide processes that translate into potential warning applications. Such efforts must be practical with respect to local expertise and facilities available.
Circuit Technology tor Mobile/Personal Communications (1994)

This paper reviews the microwave circuit technology recently developed by NTT Mobile Communications Network Inc. (NTT DoCoMo) for mobile/personal communication systems. The circuit construction techniques of highly efficient power amplifiers and high speed frequency synthesizers, which are the keys to achieve new sophisticated systems, are focused on. They include the high efficiency Harmonic-Reaction-Amplifier (HRA), the Harmonic-Matching and Reflection-Amplifier (MHRA), and the Linearized-Saturation-Amplifier with Bidirectional-Control (LSA-BC) for portable radio units, the very low distortion Self-Adjusting-Feed-Forward amplifier (SAFF) for radio base stations, and the high-speed frequency changeable Twin-Counter-Digital-Loop-Preset-Synthesizer (TC-DLPS) for digital portable radio units.
Negative Thermal Expansion up to 1000°C of ZrTiO<sub>4</sub>-Al<sub>2</sub>TiO<sub>5</sub> Ceramics for High-Temperature Applications (2007)

High temperature structural ceramics based on Al2TiO5-ZrTiO4 (ZAT) having excellent thermal-shock-resistance were synthesized by a reaction sintering. The ZAT ceramics sintered at 1600oC had a negative thermal expansions up to 1000oC and a much lower thermal expansion coefficient (0.3 ~ 1.3 x 10-6 /K) than that of polycrystalline Al2TiO5 (1.5 x 10-6 /K). These low thermal expansion are apparently due to a combination of microcracking caused by the large thermal expansion anisotropy of the crystal axes of the Al2TiO5 phase. The microstructural degradation of the composites after various thermal treatment for high temperature applications were analyzed by scanning electron microscopy, X-ray diffraction, ultrasonic and dilatometer.
RNN-Based Path Prediction of Obstacle Vehicles With Deep Ensemble (2019)

In this paper, a new approach for obstacle vehicle path prediction, which is important for advanced driver assistance systems (ADAS) and autonomous vehicles, is proposed based on a deep neural network. In order to analyze sequential sensor data, a recurrent neural network (RNN) is used and the input data for RNN is drawn from three sensors: LIDAR, camera and GPS. These sensor data are obtained experimentally with real vehicles. In addition, deep ensemble is used for robustness of the estimation and acquisition of the uncertainty. The predicted path of the proposed method is continuous and it predicts both short-term and long-term path with a single algorithm. The size of the network model is small, but it shows good performance in predicting future trajectory of obstacle vehicles.
N‐formyl peptide receptor‐1 is important for homeostasis of intestinal epithelial cells (2012)

N‐formyl peptide receptors (FPRs), which in humans include FPR1, FPR2 and FPR3, are an important family of pattern recognition receptors that bind an array of bacterial as well as host derived peptide and nonpeptide ligands. FPRs are G protein coupled surface receptors, which are well described in mediating phagocyte functions. We have demonstrated FPRs on the apical surface of intestinal epithelial cells (IEC) and have shown that in IECs FPR induces ROS generation in response to bacterial fMLF (a formylated tripeptide), viable Lactobacillus rhamnosus GG, and endogenous annexin A1 mimetic (Ac 2‐26). Furthermore, we showed that FPR‐elicited ROS activates the noninflammatory ERK MAPK pathway and enhances migration of IECs. We hypothesize that FPR1, the high‐affinity receptor, is important for motility of intestinal epithelia. Mice deficient in FPR1 demonstrates normal intestinal tissue architecture; however, intestinal crypts of the FPR1 null mouse contain more proliferating cells, and show slower migration along the crypt‐villus axis. These data suggest that FPR1 is important in maintaining homeostasis of the intestinal epithelia.
1/4 W optical receiver and clock recovery circuit for Gb/s digital fiberoptic links (2002)

Design and simulation of a low power consuming MMIC chip set is presented in this paper, which is used as an optical receiver and clock recovery circuit operating up to 1.25 Gb/s. This design is based on BTA24 Si BJT transistor array from Bipolarics. Major design innovations such as push-pull self-oscillating mixer and a push-push frequency doubler is used to provide a total power consumption of 247 mW in an area of only 700 /spl mu/m/spl times/700 /spl mu/m.
Canadian Multicenter Susceptibility Study, with a focus on cephalosporins, from 15 Canadian medical centers. The Canadian Multicenter Study Group (1997)

We have previously reported on the in vitro susceptibilities of 4,482 microorganisms to 10 antimicrobial agents tested as part of a Canadian multicenter study. We now report on the remaining 10 agents tested in that study. Of the cephalosporins reported here, ceftriaxone had the greatest activity (82 to 100% susceptible isolates) against Enterobacteriaceae, compared to ceftizoxime (78 to 100%) and cefoperazone (78 to 100%). Cefoperazone activity against Pseudomonas aeruginosa was 87%, compared to 92% for ticarcillin-clavulanate. All agents had 97% or greater activity against Staphylococcus aureus.
Multivariate statistical process control using mixture modelling (2005)

Abstract When performing process monitoring, the classical approach of multivariate statistical process control (MSPC) explicitly assumes the normal operating conditions (NOC) to be distributed normally. If this assumption is not met, usually severe out‐of‐control situations are missed or in‐control situations can falsely be seen as out‐of‐control. Combining mixture modelling with MSPC (MM‐MSPC) leads to an approach in which non‐normally distributed NOC regions can be described accurately. Using the expectation maximization (EM) algorithm, a mixture of Gaussian functions can be defined that, together, describe the data well. Using the Bayesian information criterion (BIC), the optimal set of Gaussians and their specific parametrization can be determined easily. Artificial and industrial data sets have been used to test the performance of the combined MM‐MSPC approach. From these applications it has been shown that MM‐MSPC is very promising: (1) a better description of the process data is given compared with standard MSPC and (2) the clusters found can be used for a more detailed process analysis and interpretation.

Thermodynamic reversibility in the superconducting fluctuation regime (1990)

Free-energy surfaces derived from magnetization data for ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7\mathrm{\ensuremath{-}}\mathrm{\ensuremath{\delta}}}$ have been measured in the fluctuation region near the transition temperature in order to determine whether the specific heat derived from magnetization data is the same as the specific heat derived from direct measurements. For ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7\mathrm{\ensuremath{-}}\mathrm{\ensuremath{\delta}}}$, there is close agreement and thermodynamic relations apply well even though totally different samples were used. For ${\mathrm{Tl}}_{2}$${\mathrm{Ba}}_{2}$${\mathrm{Ca}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{10}$ and ${\mathrm{Tl}}_{2}$${\mathrm{Ba}}_{2}$${\mathrm{CaCu}}_{2}$${\mathrm{O}}_{8}$, there is qualitative agreement with direct measurements, but the specific-heat data were taken on a mixed-phase sample.
[Predictive factors of the therapeutic result in the prevention of auricular fibrillation. Role of electrophysiological studies]. (1988)

A population of 50 patients suffering from paroxysmal attacks of atrial fibrillation was studied prospectively to evaluate the prognostic value of 20 variables: 6 clinical variables: sex, age, cardiopathy, number of arrhythmic attacks, "vagal" triggering, failure of class IA antiarrhythmic agents; 3 echocardiographic variables: left ventricular diastolic diameter and percentage of fibre shortening, left atrial diameter; 6 basic electrophysiological data: threshold, refractory periods at 110 and 150/min, modalities of induction of a sustained arrhythmia; 4 results observed with an infusion of flecainide in doses of 2 mg/kg: arrest or persistence of the arrhythmia, whether or not it could be reinduced and value of refractory periods; doses of flecainide administered orally. With a mean +/- SD follow-up period of 7.7 +/- 7.3 months, preventive treatment with flecainide 233 +/- 7 mg failed in 16 patients (32 per cent) and succeeded in 34 patients (68 per cent). Analysis of Kaplan-Meier curves and use of Cox's multidimensional model showed that two electrophysiological data were of prognostic value: atrial effective refractory period, and non-inducibility of the arrhythmia after intravenous administration of flecainide. Thus, the probability of failure increases with the refractory period value and decreases with the non-inducibility of the arrhythmia.
Superconformal film growth: Mechanism and quantification (2005)

Superconformal electrodeposition of copper is explained by the recently developed curvature-enhanced-accelerator coverage (CEAC) model, which is based on the assumptions that 1) the local growth velocity is proportional to the surface coverage of the accelerator, or catalyst, and 2) the catalyst remains segregated at the metal/electrolyte interface during copper deposition. For growth on nonplanar geometries, this leads to enrichment of the catalyst on advancing concave surfaces and dilution on advancing convex sections, thereby giving rise to bottom-up superfilling of submicrometer trenches and vias. In this paper the robustness of the CEAC model is demonstrated by characterizing the kinetics of catalyst accumulation and consumption in a series of electroanalytical experiments on planar electrodes. The model is then used to successfully predict interface shape evolution during feature filling in a variety of experiments, without using adjustable parameters.
Mechanisms of cytokine cascade activation in patients with sepsis: normal cytokine transcription despite reduced CD14 receptor expression. (1993)

These data indicate that in patients with septic shock, lipopolysaccharide-mediated signaling and cytokine transcription are unchanged despite a significant reduction of CD14 expression and density on monocytes. Thus, lipopolysaccharide-induced activation of monocytes from patients with sepsis may occur through direct binding of lipopolysaccharide to the CD11-CD18 complex or other lipopolysaccharide receptors, whereas binding of the lipopolysaccharide-lipopolysaccharide-binding protein complex to the CD14 receptor may not play a pivotal role in sepsis.
Complex responses to culture conditions in Pseudomonas syringae pv. tomato DC3000 continuous cultures: The role of iron in cell growth and virulence factor induction (2009)

The growth of a model plant pathogen, Pseudomonas syringae pv. tomato DC3000, was investigated using a chemostat culture system to examine environmentally regulated responses. Using minimal medium with iron as the limiting nutrient, four different types of responses were obtained in a customized continuous culture system: (1) stable steady state, (2) damped oscillation, (3) normal washout due to high dilution rates exceeding the maximum growth rate, and (4) washout at low dilution rates due to negative growth rates. The type of response was determined by a combination of initial cell mass and dilution rate. Stable steady states were obtained with dilution rates ranging from 0.059 to 0.086 h(-1) with an initial cell mass of less than 0.6 OD(600). Damped oscillations and negative growth rates are unusual observations for bacterial systems. We have observed these responses at values of initial cell mass of 0.9 OD(600) or higher, or at low dilution rates (<0.05 h(-1)) irrespectively of initial cell mass. This response suggests complex dynamics including the possibility of multiple steady states.Iron, which was reported earlier as a growth limiting nutrient in a widely used minimal medium, enhances both growth and virulence factor induction in iron-supplemented cultures compared to unsupplemented controls. Intracellular iron concentration is correlated to the early induction (6 h) of virulence factors in both batch and chemostat cultures. A reduction in aconitase activity (a TCA cycle enzyme) and ATP levels in iron-limited chemostat cultures was observed compared to iron-supplemented chemostat cultures, indicating that iron affects central metabolic pathways. We conclude that DC3000 cultures are particularly dependent on the environment and iron is likely a key nutrient in determining physiology.
Assessing the effect of system reconfiguration to enhance the capacity of electric-vehicle charging stations in radial distribution systems (2016)

The number of circulating electric-vehicles (EVs) will increase significantly in the coming years. This makes it essential to improve the hosting capacity margins for EV charging stations (EVCSs) in distribution systems. This paper assesses the potential of reconfiguration to enhance the capacity of EVCSs to avoid large investments in system upgrades. The non-coincident nature of regular and EVCSs demands are considered. The problem is formulated as a mixed-integer and nonlinear optimization problem that aims to maximize the capacity of EVCSs. The problem constraints are the limits of the bus voltages and branch currents, as well as topology constraints. The results indicate that system reconfiguration for multi-period scenarios can improve the capacity of EVCSs significantly.
Novel Immunoregulatory B Cell Pathways Revealed by lpr-+ Mixed Chimeras (1998)

lpr, a murine mutation of the Fas apoptosis receptor, causes lymphadenopathy and autoantibody production, with lymphadenopathy primarily due to a population of CD4-CD8-B220+ T cells. Previous in vivo experiments, in which lpr and normal bone marrow cells were coinfused into lpr hosts, have demonstrated that only T cells of lpr origin accumulated abnormally and only B cells of lpr origin produced autoantibodies. Moreover, in these chimeras, B cells of normal origin were unable to respond to conventional, T cell-dependent exogenous Ag. To address the role of lpr B cells in regulation of lpr autoimmunity, we have prepared lpr-+ mixed chimeras and selectively eliminated lpr B cells using allele-specific, mAb treatment, thus allowing normal B cells to develop in an environment with lpr T cells. From these data, we arrived at four major conclusions: 1) Compared with control-treated chimeric mice, lpr B cell-depleted mice had greatly reduced total lymph node cell counts; 2) the T cells were derived equally from normal and lpr donors, and the percentage of lpr-derived CD4-CD8- T cells was greatly reduced; 3) despite the presence of the remaining lpr T cells, no autoantibodies were produced by the normal derived B cells; and 4) lpr T cells without lpr B cells were unable to prevent a normal B cell response to conventional Ag. These data demonstrate that B cells can play a critical and expansive regulatory role, not only for T cells, but for other B cells as well.

801. RNA Gene Therapy Targeting Herpes Simplex Virus (2006)

Purpose: Herpes Simplex Keratitis (HSK) is the leading cause of corneal blindness in developed nations. Despite active antiviral drugs (nucleoside analogues), there is no effective method preventing recurrent HSK. We tested the ability of ribozymes targeting the mRNAs of essential HSV genes to inhibit viral infection in vitro and in vivo. Methods: Hammerhead ribozymes were designed against mRNAs of four essential HSV genes and those with the best cleavage kinetics were packaged in an adenoviral vector containing a CMV promoter and an IRES-GFP element. HSV-1 viral yields (infection at low MOI) following Ad-ribozyme treatment were compared to control cells transduced with adenovirus vector without ribozyme. After ribozyme treatment and HSV-1 infection (high MOI) total RNAs were extracted and a reverse transcription reaction followed by Real-time PCR to quantify target as well as GAPDH level was conducted. The UL20 ribozyme was tested in vivo using a protected ribozyme containing 2' modifications of the ribose sugars of selected nucleotides. This modified ribozyme was delivered to the right eyes of rabbits by iontophoresis; and an inactive ribozyme served as a control in left eyes, followed by inoculation of HSV-1 replicating virus expressing β-galactosidase. Three days post- infection, rabbits were sacrificed and corneas were harvested for X-gal staining to visualize the viral infection. Results: The UL20 ribozyme delivered by adenoviral vector reduced HSV-1 viral yield by 83% in the cell culture when cells were infected with HSV-1 for 24 hours in the presence of the ribozyme. In a time course study, the UL20 ribozyme reduced viral replication by 98% after 6 days of HSV-1 infection, indicating a cumulative effect of ribozyme cleavage. The real-time PCR results indicated that UL20 ribozyme reduced target mRNA level by 64%. The chemically stabilized UL20 ribozyme reduced HSV-1 reduced dendrite lesion area by 57% compared with the rabbit eyes treated with an inactive ribozyme. Another ribozyme targeting UL30 mRNA, whose gene product is viral DNA polymerase, was able to reduce viral replication by 98% at one day post HSV-1 infection and maintain the inhibition effect by 99% at third day post infection. Conclusions: A hammerhead ribozyme targeting the mRNA of UL20 gene (a late essential HSV-1 gene) significantly reduced the severity of an HSV-1 ocular infection in rabbits as well as significantly knocking down viral yield in cell culture. And a ribozyme targeting UL30 mRNA achieved the similar effect in the cell culture. These results suggest a RNA gene therapy strategy targeting HSV-1 early/late genes that should lack the toxicity and reduce the risk of generating drug resistant virus. Further studies evaluating the long term efficacy of different viral vectors to deliver therapeutic ribozymes during acute or recurrent HSV-1 infection are currently underway.
Hate Speech on Twitter: A Pragmatic Approach to Collect Hateful and Offensive Expressions and Perform Hate Speech Detection (2018)

With the rapid growth of social networks and microblogging websites, communication between people from different cultural and psychological backgrounds has become more direct, resulting in more and more “cyber”conflicts between these people. Consequently, hate speech is used more and more, to the point where it has become a serious problem invading these open spaces. Hate speech refers to the use of aggressive, violent or offensive language, targeting a specific group of people sharing a common property, whether this property is their gender (i.e., sexism), their ethnic group or race (i.e., racism) or their believes and religion. While most of the online social networks and microblogging websites forbid the use of hate speech, the size of these networks and websites makes it almost impossible to control all of their content. Therefore, arises the necessity to detect such speech automatically and filter any content that presents hateful language or language inciting to hatred. In this paper, we propose an approach to detect hate expressions on Twitter. Our approach is based on unigrams and patterns that are automatically collected from the training set. These patterns and unigrams are later used, among others, as features to train a machine learning algorithm. Our experiments on a test set composed of 2010 tweets show that our approach reaches an accuracy equal to 87.4% on detecting whether a tweet is offensive or not (binary classification), and an accuracy equal to 78.4% on detecting whether a tweet is hateful, offensive, or clean (ternary classification).
