VSP reverse time migration: theoretical model study and application (2018)

VSP imaging technology has played an important role in reservoir geophysical application, but the imaging accuracy of VSP data still has room to be improved. In this paper, high precision reverse time imaging technology is applied to VSP data. Based on the reverse time migration method of conventional ground seismic data, the VSP reverse time imaging condition is optimized, the regularization reconstruction technique in time-frequency domain and the stable phase VSP reverse time imaging technique are adopted. The fault artifacts caused by uneven observation and acquisition are effectively suppressed, and the accuracy and reliability of VSP reverse time imaging are improved. The accuracy and validity of the VSP reverse imaging technique are verified by using 3D VSP salt theoretical model and WVSP data of L well in Songliao Basin.
Enhanced medial axis interpolation algorithm and its application to hotspot prediction in a mould–casting assembly (2005)

The use of a medial axes transformation technique to predict temperature profile and hot spots in solidifying castings is investigated. In essence, a simplistic yet comprehensive temperature interpolation algorithm is proposed, which can solve the solidification problem qualitatively and quantitatively. The method combines the advantages of geometric reasoning and conventional numerical simulation. Previous work by the authors (valid only for a casting geometry without a mould) is enhanced and modified to take into account the effect of the mould and to consider the interaction of the whole mould–casting assembly. The feasibility of the proposed technique is demonstrated by comparison with both a pure geometric reasoning technique and finite element modelling. In addition, numerical predictions of the model are validated against real-life casting geometries
Measurement of thee+e−→pp¯cross section in the energy range from 3.0 to 6.5 GeV (2013)

The ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}p\overline{p}$ cross section and the proton magnetic form factor have been measured in the center-of-mass energy range from 3.0 to 6.5 GeV using the initial-state radiation technique with an undetected photon. This is the first measurement of the form factor at energies higher than 4.5 GeV. The analysis is based on $469\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of integrated luminosity collected with the BABAR detector at the PEP-II collider at ${e}^{+}{e}^{\ensuremath{-}}$ center-of-mass energies near 10.6 GeV. The branching fractions for the decays $J/\ensuremath{\psi}\ensuremath{\rightarrow}p\overline{p}$ and $\ensuremath{\psi}(2S)\ensuremath{\rightarrow}p\overline{p}$ have also been measured.
Changing pulse-shape basis for molecular learning control (2004)

We interpret the results of a molecular fragmentation learning control experiment. We show that in the case of a system where control can be related to the structure of the optimal pulse matching the vibrational dynamics of the molecule, a simple change of pulse-shape basis in which the learning algorithm performs the search can reduce the dimensionality of the search space to one or two degrees of freedom.
Enzyme Applications, Industrial (2000)

Abstract Enzyme technology has been used in industrial applications since ancient Greece. The era of modern industrial enzyme technology began in 1874 with the extraction of chymosin from dried calves' stomachs. The detergent industry is the largest user of industrial enzymes, utilizing proteases, amylases, lipases, and cellulases to remove soilings, increase softness, and protect fabric. The starch industry, which was the first significant user of enzymes, uses pullanases and a variety of amylases for the liquefication, saccharification, and isomerization of starches. Enzymes also find use in the textile, tannery, pulp and paper production, and animal feed industries. Another important industrial application of enzymes is in the food industry, ie, dairy, bakery, brewing, and protein modification industries. Industrial applications of enzymes are regulated. Production of industrial enzymes involves fermentation, recovery, and purification. A variety of host microorganisms are used to optimize fermentation techniques. Catalytic activity, kinetics, and response to temperature and pH affect the use of enzymes in industrial applications. Genetic engineering of enzymes is used to modify and improve natural enzymes, including increased protein production and increased genetic and product stability.

Analysis of Launch and Earth Departure Architectures for Near-Term Human Mars Missions (2008)

This paper presents a co mparative analysis of launch and Earth departure strategies for human Mars missions. A variety of Earth departure architectures are analyzed with regard to their trans -Mars injection capabilities (performance surrogate metric) and equipment and operational requirements (cost surrogate metric); it is assumed that aerocapture and chemical propulsion are used for all maneuvers in Mars vicinity for all architectures . The architectures are based on chemical propulsion (custom stages or Ares V Earth Departure Sta ge) as well as nuclear thermal propulsion. Consideration is also given to the impact of different Earth departure options on Mars aerocapture and Mars entry, descent and landing. The comparative aspect of the analysis consists of an iso -TMI mass analysis f or the different options. Results of the set of architectures indicate that while chemical Earth departure strategies results in a 30 – 50 % increase in the number if Ares V launches required per mission, the associated additional marginal cost may be outw eighed by the cost of developing and maintaining a nuclear thermal propulsion capability, as well as the increased marginal cost of nuclear thermal propulsion stages. In addition, chemical Earth departure strategies side -step the sensitive issue of space n uclear applications that would be associated with nuclear thermal propulsion.
Implanting CoOx Clusters on Ordered Macroporous ZnO Nanoreactors for Efficient CO2 Photoreduction (2022)

Despite suffering from slow charge-carrier mobility, photocatalysis is still an attractive and promising technology toward producing green fuels from solar energy. An effective approach is to design and fabricate advanced architectural materials as photocatalysts to enhance the performance of semiconductor-based photocatalytic systems. Herein, metal-organic-framework-derived hierarchically ordered porous nitrogen and carbon co-doped ZnO (N-C-ZnO) structures are developed as nanoreactors with decorated CoO<sub>x</sub> nanoclusters for CO<sub>2</sub> -to-CO conversion driven by visible light. Introduction of hierarchical nanoarchitectures with highly ordered interconnected meso-macroporous channels shows beneficial properties for photocatalytic reduction reactions, including enhanced mobility of charge carriers throughout the highly accessible framework, maximized exposure of active sites, and inhibited recombination of photoinduced charge carriers. Density functional theory calculations further reveal the key role of CoO<sub>x</sub> nanoclusters with high affinity to CO<sub>2</sub> molecules, and the CoO bonds formed on the surface of the composite exhibit stronger charge redistribution. As a result, the obtained CoO<sub>x</sub> /N-C-ZnO demonstrates enhanced photocatalysis performance in terms of high CO yield and long-term stability.
Alemtuzumab for Severe Steroid-Refractory Gastrointestinal Acute Graft-versus-Host Disease (2014)

Acute graft-versus-host disease (aGVHD) still remains the main cause of morbidity and mortality after allogeneic stem cell transplantation. Moreover, patients who did not respond to first-line treatment with glucocorticosteroids have a very poor outcome. Some studies suggested that alemtuzumab (a humanized monoclonal antibody against the CD52 antigen) might be effective for treatment of refractory aGVHD. Here we report a single-center experience with alemtuzumab in refractory gastrointestinal aGVHD. From September 2009 to April 2012 at the Grenoble medical university center, 24 patients who had presented a refractory gastrointestinal aGVHD to corticosteroid, or after another immunosuppressive drug, were retrospectively analyzed. Most patients (n = 19) presented stage 4 gastrointestinal aGVHD. Response to treatment (either complete or partial) was observed in 15 patients (62.4%). The overall survival rate at 1 year for all patients was 33.3% (95% confidence interval [CI], 15.9% to 51.9%) and for responders, 53.3% (95% CI, 26.3% to 74.4%). Two patients died from infection, 5 patients from recurrent GVHD, and 1 from an uncontrolled post-transplant lymphoproliferative disorder.

DESIGN AND CHARACTERIZATION OF A DESK-TOP LASER PLASMA X-RAY SOURCE FOR RADIOBIOLOGY STUDIES (2016)

A compact desk-top laser-produced plasma source of soft X-rays for radiobiology research is presented. The source is based on a double-stream gas puff target and delivers nanosecond pulses of soft X-rays in the "water window" spectral range at a fluence of about 4.2310 3 photon/m 2 per pulse on a sample placed inside the vacuum source chamber and about 2.6010 2 photon/m 2 per pulse on a wet sample located outside the chamber in the Heenvironment. The source has been used to irradiate pBR322 plasmid DNA both in vacuum and the He-environment conditions. Single and double strand breaks were quantified by gel electrophoresis. The number of strand breaks increased with the increasing dose of the "water window" soft X-rays. The strand breaks of plasmid solution irradiated in helium condition may be associated with damage from water-free radicals.
Magnetically Separable Base Catalysts: Heterogeneous Catalysis vs. Quasi-Homogeneous Catalysis (2012)

The synthesis of magnetically separable quasi-homogeneous base catalyst and heterogeneous base catalyst is described. The quasi-homogeneous catalyst is achieved by supporting silane monomers functionalized with different amine groups directly on the surface of magnetite nanoparticles. The heterogeneous catalyst is prepared via a sol-gel process in which silane monomers containing different amine groups are copolymerized with tetraethoxysilane in the presence of magnetite nanoparticles functionalized with ionic liquid moieties. The reactivity of the quasi-homogeneous and the heterogeneous base catalysts is compared in the nitroaldol condensation.
Regulation of the CD95 gene by the p53 family network- the intronic binding site is essential (2008)

Introduction: The p53 family members p63 and p73 give rise to proteins that have p53-agonistic as well as p53-antagonistic functions. p63 and p73 express two main classes of isoforms: isoforms which contain the transactivation domain (TAp73 and TAp63) and dominant negative isoforms (DeltaNp63 and DeltaNp73) acting as operant inhibitors of TAp73, TAp63 and wild-type (wt) p53. We aimed to provide insight into the molecular mechanisms of the regulation and transactivation of the CD95 gene by the p53 family.
Orthogonal-state-based and semi-quantum protocols for quantum private comparison in noisy environment (2016)

Private comparison is a primitive for many cryptographic tasks, and recently several schemes for the quantum private comparison (QPC) have been proposed, where two users can compare the equality of their secrets with the help of a semi-honest third party (TP) without knowing each other's secret and without disclosing the same to the TP. In the exisiting schemes, secrecy is obtained by using conjugate coding, and considering all participants as quantum users who can perform measurement(s) and/or create states in basis other than computational basis. In contrast, here we propose two new protocols for QPC, first of which does not use conjugate coding (uses orthogonal states only) and the second one allows the users other than TP to be classical whose activities are restricted to either reflecting a quantum state or measuring it in computational basis. Further, the performance of the protocols is evaluated under various noise models.
Dual-mode oscillators for clocks and sensors (2003)

Frequency can be measured with far higher accuracy than any other quantity. Dual mode excitation of resonators allows the highly accurate measurement of, and compensation for, the effects of temperature, pressure, etc., by means of frequency measurements alone. In dual mode excitation, the two excited modes occupy the same volume of quartz, thereby eliminating gradients between the resonator and sensor. This paper reviews the dual-mode technique and its applications in oscillators, clocks and sensors.

Medication Errors in a Swiss Cardiovascular Surgery Department: A Cross-Sectional Study Based on a Novel Medication Error Report Method (2013)

The purpose of this study was (1) to determine frequency and type of medication errors (MEs), (2) to assess the number of MEs prevented by registered nurses, (3) to assess the consequences of ME for patients, and (4) to compare the number of MEs reported by a newly developed medication error self-reporting tool to the number reported by the traditional incident reporting system. We conducted a cross-sectional study on ME in the Cardiovascular Surgery Department of Bern University Hospital in Switzerland. Eligible registered nurses (n = 119) involving in the medication process were included. Data on ME were collected using an investigator-developed medication error self reporting tool (MESRT) that asked about the occurrence and characteristics of ME. Registered nurses were instructed to complete a MESRT at the end of each shift even if there was no ME. All MESRTs were completed anonymously. During the one-month study period, a total of 987 MESRTs were returned. Of the 987 completed MESRTs, 288 (29%) indicated that there had been an ME. Registered nurses reported preventing 49 (5%) MEs. Overall, eight (2.8%) MEs had patient consequences. The high response rate suggests that this new method may be a very effective approach to detect, report, and describe ME in hospitals.
RAF: A Random Access First Cache Management to Improve SSD-Based Disk Cache (2010)

Offering better performance for random access compared to conventional hard disks and providing larger capacity and lower cost than DRAM, NAND flash based SSDsare integrated in server storage hierarchy as a second tier of disk cache between DRAM and disks for caching more data from disks to meet the increasingly intensive I/O demands. Unfortunately, available hybrid storage architectures cannot fully exploit SSDs' potentials due to absorbing too much workload of disk tier, which results in excessive wear and performance degradation associated with internel garbage collection. In this paper, we propose RAF (Random Access First), an hybrid storage architecture that combines both of an SSD based disk cache and a disk drive subsystem. RAF focuses on extending the lifetime of SSD while improving system performance through providing priority to caching random-access data. In detail, RAF splits flash cache into read and write cache to service read/write requests respectively. Read cache only holds random-access data that are evicted from file cache to reduce flash wear and write hits. Write cache performs as a circular write-through log so as to improve system response time and simplify garbage collection. Similar to read cache, write cache only caches random-access data and flushes them to hard disks immediately. Note that, sequential access are serviced by hard disks directly to even the full workload between SSD and disk storage. RAF is implemented in Linux kernel 2.6.30.10. The results of experiments show that RAF can significantly reduce flash wear and improve performance compared with the state-of-art FlashCache architecture.

Fault diagnosis and fault tolerant control of mobile robot based on neural networks (2009)

This paper presents a method based on neural networks for achieving fault diagnosis and fault tolerant control of the mobile robot control. The neural network state observer is trained by real nonlinear control system. From the residual difference between outputs of actual system and neural network observer, the fault of control system is detected and determined. Fault tolerant control is realized by using compensation controller and can guarantee the stability and performance. As an example of the application, a tracking control problem for the speed and azimuth of a mobile robot driven by two independent wheels is solved by using the controller. The results of simulation show the effectiveness of the proposed method with scaling location of the fault and the time of occurrence, and eliminating the noise and offering high robustness.
Possible identification of a high-latitude X-ray source with a QSO by the Astronomical Netherlands Satellite (1975)

A recently discovered QSO, NAB 0137--01, located in proximity to the high galactic latitude X-ray source 3U 0138--01 was observed using the Hard X-ray Experiment on the Astronomical Netherlands Satellite. A flux of 0.33plus-or- minus0.14 counts s$sup -1$ (1.3--7.0 keV) was detected, consistent with the intensity of 3U 0138--01. The error box for the X-ray source is thus reduced to 0.02 square degrees, greatly increasing the likelihood that the association of the X-ray source with the QSO is not accidental. The intrinsic luminosity of the QSO is about 2times10$sup 46$ ergs s$sup -1$, with an X-ray to optical luminosity ratio of 50. (AIP)
Etherification Reactions of Furfuryl Alcohol in the Presence of Orthoesters and Ketals: Application to the Synthesis of Furfuryl Ether Biofuels (2018)

Strategies for the efficient transformation of abundant and sustainable bioderived molecules, such as furfuryl alcohol (FAlc), into higher value products are currently a vibrant research area. Herein, we demonstrate that furfuryl ethers, which are of significant interest as biorenewable fuel additives, are efficiently produced employing an etherification reaction of furfuryl alcohol and short chain alkyl alcohols in the presence of a recyclable ZSM-5 catalyst and an orthoester, such as trimethyl orthoformate (TMOF) or triethyl orthoformate (TEOF), used as a sacrificial reagent. These etherification reactions proceed at temperatures significantly lower than those of the previous etherification procedures, and they provide the furfuryl ether products in high yield. Importantly, the low temperature employed improves the selectivity by minimizing the formation of hydrolysis products and the competing polymerization reactions leading to humin byproducts. By carrying out the reaction in higher alcohol solvents, such as ethanol, 1-propanol, and 1-butanol, we are able to capitalize on the ability of ZSM-5 to catalyze the orthoester exchange reaction of TMOF or TEOF to produce the corresponding furfuyl ethers in a novel, telescoped orthoester exchange–etherification reaction sequence. Finally, we also demonstrate that the etherification reaction proceeds efficiently in the presence of acetals and ketals, such as dimethoxypropane and diethoxypropane. This latter development is highly significant given the greater scope for the regeneration of acetal and ketal reagents.
An Efficient Offloading Algorithm Based on Support Vector Machine for Mobile Edge Computing in Vehicular Networks (2018)

In vehicular networks, Mobile Edge Computing (MEC) is applied to meet the offloading demand from vehicles. However, the mobility of vehicles may increase the offloading delay and even reduce the success rate of offloading, because vehicles may access another road side unit (RSU) before finishing offloading. Therefore, an offloading algorithm with low time complexity is required to make the offloading decision quickly. In this paper, we put forward an efficient offloading algorithm based on Support Vector Machine (SVMO) to satisfy the fast offloading demand in vehicular networks. The algorithm can segment a huge task into several sub-tasks through a weight allocation method according to available resources of MEC servers. Then each sub-task is decided whether it should be offloaded or executed locally based on SVMs. As the vehicle moves through several MEC servers, sub-tasks are allocated to them by order if they are offloaded. Each server ensures the sub-task can be processed and returned in time. Our proposed algorithm generate training data through Decision Tree. The simulation results show that the SVMO algorithm has a high decision accuracy, converges faster than other algorithms and has a small response time.
