Laser‐Assisted Synthesis of Colloidal FeWxOy and Fe/FexOy Nanoparticles in Water and Ethanol (2018)

Homogeneous polycrystalline Fe<sub>x</sub> O<sub>y</sub> nanoparticles were generated by ablation of iron targets in water by nanosecond laser pulses at 532 nm. In ethanol, crystalline core-shell Fe/Fe<sub>x</sub> O<sub>y</sub> structures with size medians around 20 nm were produced. The ablation of FeW<sub>x</sub> O<sub>y</sub> targets in water resulted in crystalline hollow shells and homogeneous FeW<sub>x</sub> O<sub>y</sub> nanoparticles. In contrast, amorphous core-shell FeW<sub>x</sub> O<sub>y</sub> nanoparticles with a median size of 17 nm were produced in ethanol. The size distribution of both the Fe<sub>x</sub> O<sub>y</sub> and the FeW<sub>x</sub> O<sub>y</sub> particles showed a slight dependence on fluence and pulse number. This may be related to primary and secondary ablation and modification mechanisms.
Dynamic balance training with sensory electrical stimulation in chronic stroke patients (2006)

A case study investigating the impact of sensory electrical stimulation during perturbed stance in one chronic stroke patient is presented. A special apparatus called the BalanceTrainer was used. It allows the application of perturbations to neurologically impaired people during standing, while protecting the subject from falling. The subject underwent two different periods of perturbation training, each lasting ten days. During the first period the subject was perturbed in eight different directions. During the second period the subject was also perturbed, but was assisted by sensory electrical stimulation of the soleus, tibialis anterior, tensor fascia latae, and vastus muscles in the impaired leg. After each period of training an assessment was carried out to measure the forces the subject applied on the ground via two force plates. The subject improved his ability to balance throughout the training, with the largest improvements during the final period when electrical stimulation was used.
STUDY OF THE DEFECTS THAT ORIGINATE AND DEVELOP IN THE TREADS OF RAILROAD WHEELS DURING SERVICE (1960)

Mechanism theories for the formation of defects that originate and develop in the treads of railroad wheels during service are presented. These defects were classified after a study of wheels that developed these defects during service and of wheels that were subjected to simulated service tests on a wheel-testing dynamometer. At least two general types of defects were found to occur during service-defects caused by stresses developed by braking and defects caused by stresses imposed by rolling loads.
Speech Analysis using Modulation-Based Features for Detecting Deception (2007)

This paper reports on the initial results of analysis of speech features for detecting deception from speech utterances. The features are derived from the amplitude- and frequency-modulation (AM and FM) behavior of speech centered at different nominal formant frequencies. Analysis of truthful and deceptive speech, both established a posteriori, by a male speaker under jeopardy shows that Teager energy-related features, amplitude envelope-based parameters, and formant variations and bandwidths at selected frequencies have a potential to show subtle variations indicative of deception. For comparison, trajectory of the fundamental frequency of voicing was found to show relatively minor variations between truthful and deceptive speech.
Inorganic-based phytohormone delivery vector of 2-chloroethylphosphonate nanohybrid: a new stimulating compound with controlled release property to increase latex production (2010)

New inorganic-based phytohormone delivery system, a stimulating compound to increase latex production was developed through hybridisation of 2-chloroethylphosphonic acid (ethephon) into the interlayer of Zn–Al-layered (ZAL) double hydroxide. The hybridisation product, ZADO, was synthesised using co-precipitation technique at pH 7.5, 0.08 M ethephon and initial molar ratio of Zn to Al, R = 4. The resulting material has a basal spacing of 11.5 Å and Fourier transform infrared spectra further supported the hybridisation episode of ethephon into the ZAL. The release behaviour of the active agent, ethephon from the nanohybrid was found to be of controlled manner, governed by pseudo-second order kinetics. These results indicate that it is possible to design and develop a new delivery system of a phytohormone, [ethephon (2-chloroethylphosphonate)] with controlled release property to increase latex production of rubber tree (Hevea brasiliensis).
5G-MoNArch Use Case for ETSI ENI: Elastic Resource Management and Orchestration (2018)

5G networks will grant spectacular improvements of the most relevant Key Performance Indicators (KPIs) while allowing resource multi-tenancy through network slicing. However, the other side of the coin is represented by the huge increase of the management complexity and the need for efficient algorithms for resource orchestration. Therefore, the management and orchestration of the network through Artificial Intelligence (AI) and Machine Learning (ML) algorithms is considered a promising solution, as it allows to reduce the human interaction (usually expensive and error-prone) and scale to large scenario composed by thousands of slices in heterogeneous environments. In this paper, we provide a review of the current standardization efforts in this field, mostly due to the work performed by the Experiential Network Intelligence (ENI) industry specification group (ISG) within the European Telecommunications Standards Institute (ETSI). Then, we thoroughly describe an exemplary use case on elastic network management and orchestration through learning solutions proposed by the 5GPPP project 5G-MoNArch and recently approved at ETSI ENI.
Defect structures in LiNbO3 (1995)

We have re-examined the infrared absorption bands due to the O-H bond-stretching vibration and the polarization characteristics in undoped and MgO-doped LiNbO3 using well-characterized crystals. It has been found that the O-H bond stretching vibrational frequency nu (OH) has a strong correlation with Nb concentration in the crystals. We have also determined the position where hydrogen enters using Novak's empirical relationship between the values of nu (OH) and the length of the hydrogen bond and the structure analysis data for the undoped crystals. On the basis of those results and the polarization characteristics, we have examined the intrinsic and the extrinsic defect structure models in LiNbO3. It has been clarified that the behaviour of nu (OH) reflects the defect structures. The behaviour of nu (OH) supports the Li-site vacancy model as the intrinsic defect structure model, and the corresponding extrinsic defect model. A brief discussion is also given of the behaviour of nu (OH) in crystals simultaneously doped with two kinds of impurity.
Design and test of a fully controllable 64&#x00D7;128 2-D CMUT array integrated with reconfigurable frontend ASICs for volumetric ultrasound imaging (2012)

Up-to-date capacitive micro-machined ultrasonic transducer (CMUT) technologies offer us the chance to shrink the size and cost of ultrasound scanners by integrating the frontend (FE) circuits into CMUT arrays. For true real-time volumetric imaging system using 2-D arrays, CMUT-on-CMOS integration techniques are promising for the development of lower cost smaller volume scanners with higher performance in terms of features and image qualities because it minimizes parasitic capacitances and ultimately improves signal-to-noise ratio (SNR). In this work we present the design and feasibility test of 2-D CMUT arrays integrated with analog front-end electronics for transmitting high voltage pulses and receiving RF echo signals.
Comparison of zona cutting and zona drilling as techniques for assisted fertilization in the mouse (1988)

Zona cutting and zona drilling of the mouse oocyte significantly increased the fertilization rate (3.8-90%) at low sperm concentrations (less than 200,000/ml) compared with zona-intact controls (0-45%). More oocytes were fertilized after zona drilling. Zona cutting was associated with a low loss of oocytes (less than 1%), no increase in polyspermy and normal development in vitro and in vivo after fertilization. There was a 4% oocyte loss rate after zona drilling, mostly due to extrusion of the oocyte from the zona during the procedure. Hatching of blastocysts occurred about 12 h earlier for zona-drilled than for zona-cut and zona-intact control oocytes. Zona drilling was associated with a higher, but not statistically significant, rate of polyspermy at all sperm concentrations tested. The proportion of zygotes developing to the blastocyst stage was not different between the techniques (zona cut, 77%; zona drilled, 66%; control, 71%). Similarly, no difference was found in the percentage of embryos implanting after blastocyst transfer to the uterine horns of pseudopregnant female mice (zona cut, 67%; zona drilled, 68%; control, 77%). Transmission electron microscopy demonstrated the induced defects in the zona with no damage to the oocyte or oolemma. Parthenogenetic activation was not seen after either of the micromanipulative techniques. Both techniques have promise for application to the human.
Part of speech n-grams and Information Retrieval (2008)

Résumé Les tentatives d’utilisation de connaissances linguistiques en recherche d’information (RI) ont commencé dans les années 1980 et se sont développées dans les années 1990, en mettant en évidence des améliorations de performance (voir les synthèses de Smeaton 1986 et 1999, Karlgren 1993, et Tait 2005). Depuis lors, ces tentatives sont allées décroissant : les performances des systèmes basiques se sont améliorées et le coût du traitement linguistique ne justifiait pas le petit bénéfice obtenu (Tait 2005). La plupart des recherches en linguistique pour la RI ont aujourd’hui tendance à se tourner vers les applications de domaines spécifiques, qui semblent mieux bénéficier de ces connaissances, comme les systèmes de question-réponse (Tait &amp; Oakes 2006). Bien que ces applications soient importantes, elles ne couvrent pas toute la recherche en linguistique pour la RI. Dans cet article, nous présentons une autre utilisation de la linguistique, plus précisément des informations sur les catégories grammaticales, pour pondérer le contenu informatif de séquences de texte. Cette pondération est une nouvelle application de la linguistique en RI et peut améliorer la performance des systèmes en général.
A protective merozoite protein of Plasmodium falciparum shares an epitope with surface antigens of Paramecium (2004)

SUMMARY A Plasmodium falciparum cDNA expression clone, λPf9, had been identified earlier as a protective epitope, using anti‐λPf9 antibodies and combinatorial phagotopes. A segment of the Pf9 gene showed homology with Paramecium immobilization surface antigens such as 51B, 51A and 156G. A synthetic Pf9‐peptide was designed from this region, and specific antibodies were raised. Each of these anti‐Pf9 antibodies and combinatorial reagents, as well as anti‐ Paramecium 51B antibodies, recognized the Pf9‐peptide on ELISA, and the same protein band in parasite immunoblots. The P. falciparum protein was released from the merozoite membrane fraction on treatment with PI‐PLC, indicating the presence of a GPI anchor. Anti‐Pf9‐peptide antibodies specifically inhibited the growth of P. falciparum in culture. Immunofluorescence assays showed the reactivity of anti‐Pf9‐peptide sera with P. falciparum merozoites and gametocytes, as well as on the surface of Paramecium tetraurelia . The Pf9‐peptide was able to induce proliferation of splenic lymphocytes obtained from mice infected with the rodent malarial parasites Plasmodium berghei and Plasmodium yoelii. These results point towards Plasmodium Pf9 as a conserved novel protective protein, sharing an epitope with Paramecium surface antigens.
A dynamic channel assignment strategy using information of speed and moving direction in micro cellular systems (2002)

High speed mobile stations (HSMSs) in microcellular systems experience the problems of forced call termination (FCT) and channel changing (CC). The author proposes a new dynamic channel assignment (DCA) strategy using information on speed and moving direction to reduce FCT and CC in HSMSs. This strategy, SMD (speed and moving direction), is compared with the other main DCA strategies through simulation having one-dimensional service area covering a road, such as a highway. The simulation results show that the SMD strategy has the best performance with regard to reducing FCT and CC in HSMSs. The results also show that the difference between the SMD performance and other DCA strategies increases as cells become smaller and HSMSs become faster.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Experimental Study on the Large Cusp Formation (2010)

In this study, the authors experimentally investigated the formation of cuspate topography and the effect of the initial topographic perturbation on the alongshore uniform barred beach with a 1/20 slope.The cuspate topographies appeared only in the cases which we generate the accretion-type waves.The perturbation added in the initial topography disappeared gradually and the positive-feedback mechanism was not observed in this study.This result indicates that the formation of cusp with positive feedback mechanism may need other certain wave condition.

A Filarial Nematode-Secreted Product Signals Dendritic Cells to Acquire a Phenotype That Drives Development of Th2 Cells (2000)

Abstract Although exogeneous “danger” signals such as LPS can activate APC to produce a Th1 response, the nature of events initiating a Th2 response is controversial. We now show that pathogen-derived products have the capacity to induce bone marrow-derived dendritic cell cultures to acquire a phenotype that promotes the differentiation of naive CD4+ T cells toward either a Th1 or Th2 phenotype. Thus, LPS-matured dendritic cells (DC1) promote a Th1 response (increased generation of IFN-γ and reduced production of IL-4) by Ag-stimulated CD4+ T cells from the DO.11.10 transgenic mouse expressing a TCR specific for an OVA peptide (OVA323–339). In contrast, a phosphorylcholine-containing glycoprotein, ES-62, secreted by the filarial nematode, Acanthocheilonema viteae, which generates a Th2 Ab response in vivo, is found to induce the maturation of dendritic cells (DC2) with the capacity to induce Th2 responses (increased IL-4 and decreased IFN-γ). In addition, we show that the switch to either Th1 or Th2 responses is not effected by differential regulation through CD80 or CD86 and that a Th2 response is achieved in the presence of IL-12.
Gif Chemistry for Oxidation of Activated Methylenes to Ketones (2002)

Gif reaction1,2 attempts to imitate the principle of oxida tion catalyzed by cytochrome P450 (P450).3,4Hydrocarbons can be thus oxidized by O2, KO2, H2O2 or t-BuOOH with Fe(II) or Fe(III) being the catalyst.Recently, Gif reagents5 have been represented by Fe(III)/t-BuOOH assisted by the presence of 2-picolinic acid to enhance rate of catalytic oxygenation (GoAggV).5,6Acetonitrile and pyridine (CH3CN/ C5H5N)7,8 were employed as the solvent for the Gif oxida tions.However, the identity of the active oxidant has been in serious dispute whether it involves radical nature or nonradical pathway.8-14The oxidation of cycloalkane10,13 using tert-butyl hydroperoxides under GoAggV conditions may involve t-BuO /t-BuOO system for the formation of cycloalkanol and cycloalkanone.We'd like to herein report the oxidation of benzylic and allylic C-H bonds which are much weaker than secondary C-H.Reduction of the bond strength may divert different reaction mechanism other than the radical pathway.Normal GoAggV employed C5H5N/ CH3COOH as solvent.However, present GoAggV condition involves C5H5N/CH3CN.FeCl3,6H2(0.2 mmol) and 2-picolinic acid (0.5 mmol) were dissolved in C5H5N (1 mL)/CHsCN (5 mL), stirred for 30 min and the substrate (10 mmol) was slowly added.30% aqueous t-BuOOH (30 mmol) was then added dropwise with syringe pump for 30 min and the reaction went on for the appropriate period.Sodium oxalate (3.73 mmol) was added to eliminate Fe(III) ion.The filterate was evaporated to dryness that was dissolved in small amount CH2Cl2 (1-2 mL) for the Silicagel column chromatography.The outcome of oxidation of various hydrocarbons are shown in Table 1.The ketonization in entries 1-4 proceeds smoothly and show excellent yield for relatively short duration.In a previous study,6 yield of 9,10-anthraquinone marked 50% which is far below 80% (entry 1).9-Fluorenone also show quite improvement of yield from 55%5 to 82% (entry 2).The oxidation of xanthene to xanthone6 took 20 h to give 82% yield.The same reaction indicates 3 h in our hand with similar isolated yield (entry 4).Ethylbenzene15 was oxidized to acetophenone by GifIV with yield of 9.4% (compare 84% of entry 5).Benzophenone was produced5 in 43% yield that becomes 92% with entry 6. Cyclohexene is oxidized to 2-cyclohexene-1-one with yield of 84% (entry 7).However, only 5% of yield of the same ketone was obtained in the foregoing study.5The less activated and
Automatic tracking of proteins in sequences of fluorescencce images (2004)

The development of digital microscopy and computational power is providing new opportunities for analyzing the motility of the vesicles (proteins) within living cells. In this paper, an automatic method is developed to segment and track vesicles in large amount of fluorescence images, in order to compute a number of quantitative parameters such as displacement, residence time, binding, or immobile fraction. We present a method that permits the automatic tracking of subcellular structures in long sequences of fluorescence images (up to 100 frames). The method we propose has been tested on 92 data sets totaling 8225 frames.
Integration of WirelessHART networks in Distributed Control Systems using PROFINET IO (2010)

In this paper we describe a method to integrate WirelessHART networks in Distributed Control Systems (DCS) using PROFINET IO. By modeling the WirelessHART network in the Generic Station Description file, that describes a PROFINET IO device, the WirelessHART related configuration can be distributed from the central engineering stations. In this way, both process controller configuration and WirelessHART network configuration is engineered and maintained from a central location. Thus the end-user does not need any additional tool-specific training, as the existing tools are used to engineer the WirelessHART networks. We base the method of integration on the keywords simple deployment and maintenance, and flexible topology. A proof-of-concept implementation of the proposed method shows that it is possible to downloadWirelessHART configuration both to the WirelessHART network managers, as well as the WirelessHART sensors. By integrating WirelessHART in this way, maintenance is greatly simplified as the actual configuration will be downloaded automatically by the DCS when faulty field devices are replaced.

Isolement par Voie Fermentaire de la Solasonine A Partir d'un Melange de Glucoalcaloides (1981)

A strain of Aspergillus niger grown on a medium containing 60% of Solamargine and 40% of Solasonine was able to hydrolyse selectively Solamargine. It was thus possible to extract pure Solasonine. Different parameters influencing the speed of hydrolysis of the Solamargine were examined.
Initial experience with a continuous mechanical aspiration system for thrombus removal before percutaneous coronary intervention (2022)

Abstract Objectives Here we investigate the safety and efficacy of a continuous mechanical aspiration system when used before percutaneous coronary intervention (PCI) in patients with acute coronary syndrome (ACS). Background Historically, trials of routine manual aspiration thrombectomy in ACS patients have reported mixed results. This may be due to the technical limitations of manual aspiration, which suffers from decreasing vacuum power as aspiration is performed. Methods This is a retrospective case series of all patients treated with continuous mechanical aspiration (Indigo CAT RX Aspiration System; Penumbra Inc.) before PCI between August 2017 and July 2020 at five centers in the United States. Data regarding angiographic assessments, procedure, and safety were examined. Results Seventy‐two patients (mean age 60 ± 12.5 years, 34.7% female) with ST Elevation Myocardial Infarction (STEMI) (80.6%) or Non‐ST Elevation Myocardial Infarction (NSTEMI) (19.4%) were included. Target vessels were the right coronary (43.1%), left anterior descending (33.3%), and left circumflex (23.6%). Preprocedure, 94.4% had a high thrombus burden (thrombolysis in myocardial infarction [TIMI] thrombus grade ≥ 3). Median aspiration time was 35 s and median access‐to‐reperfusion time was 10 min. After CAT RX alone, 86.1% had complete perfusion (TIMI flow grade 3). After the procedure, 94.4% had TIMI thrombus grade &lt;3% and 97.2% had TIMI flow grade 3. There were no cases of ischemic stroke. Cardiovascular mortality at 30 days was 1.4%. Conclusions In our initial experience, aspirating thrombus from ACS patients using the Indigo CAT RX Aspiration System before PCI was safe and effective for reducing thrombus burden and restoring flow.

ASFC-based DNN Modeling for Prediction of Silicon Content in Blast Furnace Ironmaking (2018)

The real-time and accurate prediction of the silicon content in the blast furnace (BF) plays an important role in controlling the temperature of the BF and stabilizing the BF condition. As the BF system model continuously changes during the smelting process, a single model may not be able to fully represent the complex operating conditions of the BF. For this reason, this paper establishes a distributed neural network model based on online adaptive semi-fuzzy clustering algorithm (ASFC-DNN) to predict the silicon content in molten iron in hope of reasonable BF control guidance. The model adopts an online self-adaptive semi-fuzzy clustering learning algorithm (ASFC) which can reflect the fuzzy clustering characteristics of BF production data. Through the hybrid clustering of production data, a distributed neural network sub-model is established for the decomposition of complex conditions. ASFC also updates the production data category to update the network parameters of the distributed neural network, and the reliable network structure for the current input production data is obtained to predict the silicon content. The performance of the ASFC-DNN is compared with the BPNN and ordinary elmanNN, and the ASF C-DNN's hit rate and RMSE are better than that of other models. The study found that the ASFC-DNN model has more stable prediction errors and higher prediction accuracy than the above models. On-site experiments demonstrate that the ASFC-DNN model has higher accuracy and better tracking performance and it provides reliable silicon content for operators.
