On improving the accuracy and reliability of GPS/INS-based direct sensor georeferencing (2007)

Due to the complementary error characteristics of the Global Positioning System&#13;\n(GPS) and Inertial Navigation System (INS), their integration has become a core&#13;\npositioning component, providing high-accuracy direct sensor georeferencing for&#13;\nmulti-sensor mobile mapping systems. Despite significant progress over the last decade,&#13;\nthere is still a room for improvements of the georeferencing performance using&#13;\nspecialized algorithmic approaches. The techniques considered in this dissertation include:&#13;\n(1) improved single-epoch GPS positioning method supporting network mode, as&#13;\ncompared to the traditional real-time kinematic techniques using on-the-fly ambiguity&#13;\nresolution in a single-baseline mode; (2) customized random error modeling of inertial&#13;\nsensors; (3) wavelet-based signal denoising, specially for low-accuracy high-noise&#13;\nMicro-Electro-Mechanical Systems (MEMS) inertial sensors; (4) nonlinear filters,&#13;\nnamely the Unscented Kalman Filter (UKF) and the Particle Filter (PF), proposed as&#13;\nalternatives to the commonly used traditional Extended Kalman Filter (EKF).&#13;\nThe network-based single-epoch positioning technique offers a better way to&#13;\ncalibrate the inertial sensor, and then to achieve a fast, reliable and accurate navigation&#13;\nsolution. Such an implementation provides a centimeter-level positioning accuracy&#13;\nindependently on the baseline length. The advanced sensor error identification using the&#13;\nAllan Variance and Power Spectral Density (PSD) methods, combined with a&#13;\nwavelet-based signal de-noising technique, assures reliable and better description of the&#13;\nerror characteristics, customized for each inertial sensor. These, in turn, lead to a more&#13;\nreliable and consistent position and orientation accuracy, even for the low-cost inertial&#13;\nsensors. With the aid of the wavelet de-noising technique and the customized error model,&#13;\naround 30 percent positioning accuracy improvement can be found, as compared to the&#13;\nsolution using raw inertial measurements with the default manufacturer’s error models.&#13;\nThe alternative filters, UKF and PF, provide more advanced data fusion techniques and&#13;\nallow the tolerance of larger initial alignment errors. They handle the unknown nonlinear&#13;\ndynamics better, in comparison to EKF, resulting in a more reliable and accurate&#13;\nintegrated system. For the high-end inertial sensors, they provide only a slightly better&#13;\nperformance in terms of the tolerance to the losses of GPS lock and orientation&#13;\nconvergence speed, whereas the performance improvements are more pronounced for the&#13;\nlow-cost inertial sensors.

Performance of the ATLAS Trigger System in 2010 (2012)

Proton-proton collisions at s = 7 TeV and heavy ion collisions at s NN = 2.76 TeV were produced by the LHC and recorded using the ATLAS experiment's trigger system in 2010. The LHC is designed with a maximum bunch crossing rate of 40 MHz and the ATLAS trigger system is designed to record approximately 200 of these per second. The trigger system selects events by rapidly identifying signatures of muon, electron, photon, tau lepton, jet, and B meson candidates, as well as using global event signatures, such as missing transverse energy. An overview of the ATLAS trigger system, the evolution of the system during 2010 and the performance of the trigger system components and selections based on the 2010 collision data are shown.
Long Term Measuring of Expansions and Contractions of Pre-Stressed Concrete Bridge Structure (2016)

The presented paper considers approx. 5 years measurement on concrete railway bridge. The span is 39.875 + 34.877 + 37.000 + 9 x 31.500 m. The total length of the bridge is 443 m. Structure possesses typical three-box cross section. Monitoring was focused on temperature of concrete, temperature of atmosphere in the shade and mainly on measurement of movements of several bearings. Because the monitoring period of bridge structure was approx. 5 year, the probability p = 0.2 (5 years returning period) was chosen in order to compare measured data with standard values according to EN 1991-1-5. Of course, the standard value was assumed without any safety factor for this purpose. The maximal difference of measured and standard values was only 25 mm. This was achieved on the pillar where measured value of displacement range was 135 mm, standard value 160 mm and the dilatation length was 332 m. On the other hand, the minimal difference was only 3 mm on the pillar where measured value was 33 mm, standard value 36 mm and the dilatation length was 75 m. If the approx. 5 years measurement is compared with theoretical value of 5 years return period, the standard procedure cannot be classified as very conservative. It was shown that the long-time measurement is very important for the further development and improvement of the Eurocodes as well as statistical approach, i.e., returning time which shall be taken into account.

Die Bedeutung der K(Killer)-Zellen (Effektorzellen der antikörperabhangigen zellvermittelten Zytotoxizität (ADCC = antibody dependent cellular cytotoxicity) sowie der NK(Natural Killer)-Zellen (Effektorzellen der „Natürlichen Zytotoxizität“) für die Pathomechanismen in der Tumorimmunologie, bei akuten und chronischen Viruserkran-kungen, bei Autoimmunleiden und bei der TransplantatabstoBung ist in den letzten Jahren zunehmend erkannt worden [1, 2].
Using finite differences methods for approximating the value function of continuous reinforcement learning problems (1996)

This paper presents a reinforcement learning method for solving continuous optimal control problems when the dynamics of the system is unknown. First, we use a finite differences method for discretizing the Hamilton-Jacobi-Bellman equation and obtain a finite Markovian Decision Process. This permits us to approximate the value function of the continuous problem with piecewise constant functions defined on a grid. Then we propose to solve this MDP on-line with the available knowledge using a direct and convergent reinforcement learning algorithm, called the Finite difference reinforcement learning. / Utilisation de méthodes aux différences finies pour définir un algorithme d'apprentissage par renforcement convergent.
Pyrrolopyrazines as Selective Spleen Tyrosine Kinase Inhibitors (2013)

We describe the discovery of several pyrrolopyrazines as potent and selective Syk inhibitors and the efforts that eventually led to the desired improvements in physicochemical properties and human whole blood potencies. Ultimately, our mouse model revealed unexpected toxicity that precluded us from further advancing this series.
Role of TMEDA in Iron-Catalyzed Coupling Reactions (2009)

Iron-catalyzed cross-coupling ­reactions are an active area of research due to the non-toxicity of iron relative to other commonly used transition metals. However, an understanding of the mechanistic processes underlying these reactions is still unclear. In the present paper, the authors study the effect of TMEDA on the cross-coupling reactions of ArMgX with alkyl halides. Based on X-ray structures of tetrahedral com­plexes 1 and 2 and radical clock experiments, the authors have proposed a possible catalytic cycle for this reaction.

Drought stress of apple trees alters leaf emissions of volatile compounds (1995)

Actively growing potted apple trees ( Malus domestica [L.] Borkh. ev. Delicious) unacclimated to drought stress were subjected to drought to determine changes in emissions of leaf volatile compounds. Drought stress was imposed over a 2‐week period by weighing pots every 2 or 3 days and adding water hack to an arbitrary and decreasing traction of the original pot weight. Stem water potential was ‐2.7. ‐2.0 and ‐0.8 MPa for the severely stressed, moderately stressed and control trees, respectively. 13 days alter watering treatments were begun. Water use the last 4 days of the experiment was about one‐half for the moderately and severely stressed trees compared to that of the controls Twenty‐nine volatile compounds were identified by using gas chromatography and mass spectroscopy. Emission rates of hexanal, (E)‐2‐hexenal, (E)‐2‐hexen‐1‐ol, 1‐hexenol, hexyl acetate and (E)‐2‐hexenyl acetate were 5 to 310 times higher for severely stressed trees compared to those of the controls with the moderately stressed trees intermediate. The large increases in hexanal. (E)‐2‐hexenal and l‐hexanol may be related. In enhanced lipoxygenase activity. Volatile compounds are products of metabolism and measurement of their changes after biotic or abiotic stresses will increase understanding of the relationship of changes in plant metabolism by those stresses.
Diesel Trap Performance: Particle Size Measurements and Trends (1998)

&lt;div class="htmlview paragraph"&gt;Particle concentrations and size distributions were measured in the exhaust of a turbocharged, aftercooled, direct-injection, Diesel engine equipped with a ceramic filter (trap). Measurements were performed both upstream and downstream of the filter using a two-stage, variable residence time, micro-dilution system, a condensation particle counter and a scanning mobility particle sizer set up to count and size particles in the 7-320 nm diameter range. Engine operating conditions of the ISO 11 Mode test were used. The engine out (upstream of filter) size distribution has a bimodal, log normal structure, consisting of a nuclei mode with a geometric number mean diameter, DGN, in the 10-30 nm range and an accumulation mode with DGN in the 50-80 nm range. The modal structure of the size distribution is less distinct downstream of the filter. Nearly all the particle number emissions come from the nuclei mode, are nanoparticles (Dp &amp;lt; 50nm), and are volatile. The emission of nanoparticles downstream of the filter is influenced strongly by the residence time; changing the residence time from 40 ms to 6000 ms increases the number concentrations of nanoparticles by up to three orders of magnitude. Residence time also considerably influences the engine out number concentrations and the shape of the size distributions, especially in the nuclei mode range. In ISO mode 8, total number concentrations vary from 47 to 600 to 311x10&lt;sup&gt;6&lt;/sup&gt; part./cm&lt;sup&gt;3&lt;/sup&gt; as residence time increased from 40 to 1000 to 6000 ms.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;The number weighted filter penetration is highly dependent on residence time. At a residence time of 40 ms, penetrations are less than 1% for nearly all operating modes, but at a residence time of 6000 ms, modes 1,2,3, and 6 gave fairly high overall penetrations of 60 %, 73%, 130 %, and 47 %, respectively. These high penetrations result from particle nucleation downstream of the filter, not inherent filtration performance.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;The filter self-regenerates when the engine is operated at the rated power condition (ISO mode 1). During regeneration, emissions of particles below 13 nm in diameter increase by more than three orders of magnitude for a few minutes.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;Particle nucleation and growth during dilution are poorly understood and strongly influence measured number emissions and size distributions. More work is needed to establish consistent, well-defined sampling and dilution procedures for measurements of particle number emissions and size, especially in the nanoparticle size range. These procedures should, to the extent possible, mimic atmospheric dilution conditions so that measurements are representative of real world exposures rather than arbitrarily defined laboratory conditions.&lt;/div&gt;
Simultaneous blockade of IL-6 and CCL5 signaling for synergistic inhibition of triple-negative breast cancer growth and metastasis (2018)

Taken together, these findings show that IL-6 and CCL5 signaling, which promote crosstalk between TNBC and lymphatic vessels, are key enhancers of TNBC tumor growth and metastasis. Furthermore, these results demonstrate that a drug combination inhibiting these pathways may be a promising therapy for TNBC patients.
Terminal latency index in neuropathy with antibodies against myelin‐associated glycoproteins (2006)

Neuropathy with antibodies against myelin-associated glycoproteins (MAG/SGPG-N) and hereditary sensorimotor neuropathy type 1 (HMSN1) are characterized by chronic demyelination with little conduction block. Electrodiagnostic studies suggest that in HMSN1 conduction slowing occurs uniformly along the nerve, whereas in MAG/SGPG-N it is predominantly distal. Some but not all previous reports have shown that the terminal latency index (TLI) was useful to distinguish MAG/SGPG-N from chronic idiopathic demyelinating polyneuropathy. We compared median TLI from 21 patients with MAG/SGPG-N with those obtained from 26 patients with HMSN1, 20 with HMSN2, and 12 healthy volunteers. All patients with TLI <0.26 had MAG/SGPG-N, and all patients with TLI > or =0.32 had HMSN1. In the remaining patients with intermediate TLI values, ulnar distal motor latency (DML) aided in differentiation between MAG/SGPG-N and HMSN1 with an overall sensitivity of 100% and specificity of 98%. In conclusion, median TLI in combination with ulnar DML can further guide the demyelinating neuropathy evaluation toward hereditary or autoimmune causes.
Theoretical and Kinematic Solution of High Reconfigurable Grasping for Industrial Manufacturing (2017)

High flexibility and high speed is the goal for industrial manufacturing. However, it is difficult to put them together due to the reason that they are contradicting with each other. The authors face this production process problem and presented a new high reconfigurable gripper. It has two degrees of freedom per finger and can support enough payload for manufacturing applications. At same time the simple kinematics permits to be fast. Moreover, not only it is able to handle different workpiece, but the same design concept, can be applied to different scenarios. In this paper the authors motivate and detail all the principals and the concepts used for define and design this gripper. The physical models are shown as proof of this successful project.

Radiation crosslinking of polyethylene–polyfunctional monomer mixtures (1964)

Abstract Polyfunctional monomers such as allyl methacrylate, allyl acrylate, and diallyl maleate have been found to greatly enhance the radiation crosslinking of polyethylene. The radiation dose for incipient gelation is decreased by a factor of approximately 25 by the presence of small amounts of these monomers. The ultimate scission/crosslinking ratio is unchanged by the presence of these monomers and the swelling behavior of the gels follows the Flory‐Rehner equation. The monomer‐crosslinking process is compared to the monomer‐free process as regards the physical properties (tensile strength, elongation, modulus) of the crosslinked materials. A mechanism is presented for the enhancement of polyethylene crosslinking by polyfunctional monomers.
Relaxation processes in insulator thin films (1992)

Relaxation peaks with the same activation energy as the DC conductivity have been observed in the low-frequency dielectric properties of insulator thin films. In particular, the authors present results for electron-beam-evaporated aluminium oxide films and sputtered hydrated nickel oxide films. The presence of the relaxation peaks seems to be correlated to the amount of hydrogen atoms present in the films. They propose a phenomenological model for the relaxation process. It is assumed that the DC conductivity is due to charge-carrier transport in electronic states positioned at a certain energy above the Fermi level. The energy difference between the Fermi level and the transport states is equal to the activation energy. Empty localized states close to the Fermi level will act as traps and give rise to a relaxation peak in the imaginary part of the dielectric permittivity.
Effects of thermal cycling on phenylethynyl-terminated PMDA-type asymmetric polyimide composites (2018)

The effects of thermal cycling on a polymerized monomeric reactant (PMR) type polyimide (TriA X) reinforced with carbon fibers were investigated. Composite specimens were subjected to 2000 thermal cycles between −54°C and 232°C. At 400-cycle intervals, laminates were inspected for microcracks, and glass transition temperature ( T g ) and short-beam shear (SBS) strength were measured. The composites did not exhibit microcracks after thermal cycling, although after 2000 thermal cycles, mechanical properties of the matrix declined slightly. The matrix degradation decreased the resistance to microcracking upon further loading. No effects of thermal oxidative aging were observed from thermal cycling, and thermally driven fatigue and creep were identified as the primary and secondary factors inducing mechanical degradation of the matrix. T g of the composites exhibited no change after 2000 cycles, while the SBS strength decreased slightly (3–9%). The results highlight the potential for use of TriA X composites as long-term structural components in high-temperature service environments.
Cyclooxygenase‐2 up‐regulation after FLAP transfection in human adenocarcinoma cell line HT29 cl.19A (1998)

Five-lipoxygenase-activating protein (FLAP) is usually described as an essential protein to activate the leukotriene (LTs) synthesis via the 5-lipoxygenase pathway. In the enterocyte model HT29 cl.19A cell line, 5-lipoxygenase metabolism was found despite the lack of FLAP expression. Therefore HT29 cl.19A represents an original mammalian model to study FLAP-dependent leukotriene synthesis. In FLAP cDNA transfected HT29 cl.19A cells, FLAP expression led to an increase in cyclooxygenase pathway products (mainly PGE2) without an increase in 5-lipoxygenase metabolism. This increase in PGE2 synthesis was associated with a cyclooxygenase-2 upregulation in comparison to untransfected HT29 cl.19A cells. These results suggest a possible interaction between the two major pathways of arachidonic acid metabolism.
Abstract 5166: Extracellular matrix protein tenascin C increases phagocytosis mediated by CD47 loss-of-function in glioblastoma (2019)

Glioblastomas (GBMs) are highly infiltrated by myeloid-derived innate immune cells that contribute to an immunosuppressive nature of the brain tumor microenvironment (TME). CD47 has been shown to mediate immune evasion as the CD47-SIRPα axis prevents phagocytosis of tumor cells by macrophages and other myeloid cells. In this study, we established CD47 homozygous deletion (CD47-/-) in human and mouse GBM cells by genome editing to investigate the impact of eliminating the “don’t eat me” signal on tumor growth and tumor-TME interactions. CD47 knockout (KO) did not significantly alter tumor cell proliferation in vitro, but significantly increased phagocytosis of tumor cells by macrophages in co-cultures. Compared with CD47 wild type xenografts, orthotopic xenografts derived from CD47-/- tumor cells grew much slower with enhanced tumor cell phagocytosis and increased recruitment of M2-like tumor associated microglia/macrophages (TAMs). CD47 KO increased tumor-associated extracellular matrix protein tenascin C (TNC) in xenografts, which was further examined in vitro. CD47 loss-of-function upregulated TNC expression in tumor cells via a Notch pathway mediated mechanism. ShRNA-based TNC knockdown in tumor cells enhanced the growth of CD47-/-xenografts in vivo, and decrease the number of TAMs. TNC knockdown inhibited phagocytosis of CD47-/- tumor cells in co-cultures. Furthermore, TNC stimulated release of pro-inflammatory factors including TNF-α via a toll-like receptor 4 (TLR4) and STAT3-dependent mechanism in human macrophage cells. These results reveal a vital immunomodulation role of TNC in brain tumor biology and demonstrate the prominence of the TME extracellular matrix in affecting the anti-tumor function of brain innate immune cells.Citation Format: Ding Ma, Senquan Liu, Bachchu Lal, John Laterra, Mary Ann Wilson, Shuli Xia.

Carbon-coated magnetic nanoparticles as a removable protection layer extending the operation lifetime of bilirubin oxidase-based bioelectrode (2020)

One of the factors hindering the development of enzymatic biosensors and biofuel cells in real-life applications is the time-dependant degradation of the biocatalysts on electrode surfaces. In this work, we present a new practical approach for extending the operation lifetimes of bioelectrocatalytic assemblies based on bilirubin oxidase (BOD). As evident by both spectroscopic and electrochemical measurements, an adsorption of carbon-coated magnetic nanoparticles (ccMNPs) onto a BOD/carbon nanotubes-deposited surface yields a stable bioelectrocathode system for mediatorless oxygen reduction. As compared to electrodes, which were stored without a preliminary interaction with the ccMNPs, an 80% increase in the active enzymatic content and the electrocatalytic performance was evident for the modified assemblies over a course of one month. As the full removal of the protective particles before the measurement requires only a single step applying an external magnetic force, the method is shown to be simple, reproducible, and easy to implement. Combined with the high efficiency in preserving the enzymatic stability and bioelectrocatalytic currents, the findings suggest a promising methodology for enhancing the lifetimes of bioelectronic applications.
Predicting Axial Impairment in Parkinson’s Disease through a Single Inertial Sensor (2022)
