Socially-Aware Large-Scale Crowd Forecasting (2014)

In crowded spaces such as city centers or train stations, human mobility looks complex, but is often influenced only by a few causes. We propose to quantitatively study crowded environments by introducing a dataset of 42 million trajectories collected in train stations. Given this dataset, we address the problem of forecasting pedestrians' destinations, a central problem in understanding large-scale crowd mobility. We need to overcome the challenges posed by a limited number of observations (e.g. sparse cameras), and change in pedestrian appearance cues across different cameras. In addition, we often have restrictions in the way pedestrians can move in a scene, encoded as priors over origin and destination (OD) preferences. We propose a new descriptor coined as Social Affinity Maps (SAM) to link broken or unobserved trajectories of individuals in the crowd, while using the OD-prior in our framework. Our experiments show improvement in performance through the use of SAM features and OD prior. To the best of our knowledge, our work is one of the first studies that provides encouraging results towards a better understanding of crowd behavior at the scale of million pedestrians.
Catalytic Bitumen Upgrading under Methane Environment (2016)

In industrial field, hydrocracking is conventionally used to upgrade crude oil and improve the quality of oil products. However, the high investment cost and strict experimental conditions limit the development of this technology. The utilization of methane, which is naturally available as the principal component of natural gas, to play the role of H donor, attracts the attentions from both the oil companies and the academic research. In this thesis, three catalytic formula are identified through the catalysts screening. All these catalysts show a significant viscosity reduction companied by acceptable coke yield, better stability and compatibility and the high liquid yield. With series of experiment results, it can be concluded that the catalysts promote the activation of methane and the incorporation into the product oil efficiently. The current achievement of this research can also further improves the commercial application feasibility of this technology.
A computational approach to the analysis of distributed Bragg reflectors in direct-gap solar cells (1996)

In this paper, the development of a detailed numerical model for analyzing direct-gap solar cells employing distributed Bragg reflectors is described. Energy-dependent reflection coefficients are computed for calculating trapping of external photons, and angular-dependent reflection is considered for trapping of photons emitted via radiative recombination. The resulting numerical model provides the ability to consider in detail the benefits and tradeoffs that arise from variations in the base thickness, base mobility and lifetime, and the distributed Bragg reflector structure itself. Example solar cell structures that may be modeled include AlGaAs/GaAs devices both on GaAs and on Si substrates, as well as novel types of GaSb-based thermophotovoltaic devices.

Babette’s Feast as Sacramental: The Eternal and the Mundane Meet (2017)

The literary discussion surrounding Babette’s Feast focuses on whether the feast was transformational due to it being either symbolic of a Eucharistic feast, a work of art produced by Babette, or a combination of both elements making it transcendental. I have found, however, that through applying the theological lens of Alexander Schmemann’s For the Life of the World, it is evident that the feast need not be anything beyond food to instigate a sacramental experience; God chooses to inhabit the mundane in order that we might experience his transformational presence, and we can access his presence by giving thanks for the food before us. By gaining a deeper understanding of the sacramental worldview as presented in Babette’s Feast, the actions of the everyday, such as eating a meal with others, can become for us opportunities to encounter the Lord’s presence.
Activated Protein C−Protein C Inhibitor Complex Formation:  Characterization of a Neoepitope Provides Evidence for Extensive Insertion of the Reactive Center Loop (2000)

Protein C inhibitor, a serine proteinase inhibitor (serpin), is the physiologically most important inhibitor of activated protein C. We have made a monoclonal antibody (M36) that binds with equally high affinity to an epitope present in activated protein C-protein C inhibitor complexes and cleaved loop-inserted protein C inhibitor. Insertion of a synthetic N-acetylated tetradecapeptide (corresponding to residues P1-P14 of the reactive center loop) into beta-sheet A of the uncleaved inhibitor also exposed the epitope. The antibody had no apparent affinity for native uncleaved inhibitor or for the free peptide. Synthetic P1-P14 analogues, with Arg P13 or Ala P9 substituted to the residues found in mouse protein C inhibitor (Thr and Ile, respectively), were also inserted in beta-sheet A. The Arg P13/Thr substitution led to a greatly impaired reactivity with the antibody, whereas the Ala P9/Ile mutation resulted in a modest loss of reactivity with the antibody. These results indicate that complex formation leads to insertion of the reactive center loop in beta-sheet A from Arg P14 and presumably beyond Ala P9. Moreover, to the best of our knowledge, this is the first instance where the neoepitope of a complexation-specific monoclonal antibody has been localized to the loop-inserted part of beta-sheet A, the part of the serpin where the complexation-induced conformational change is most conspicuous.
Tuning the Dimensions of ZnO Nanorod Arrays for Application in Hybrid Photovoltaics (2012)

ZnO nanorod arrays are a very eligible option as electron acceptor material in hybrid solar cells, owing to their favorable electrical properties and abundance of available, easy, and low-cost synthesis methods. To become truly effective in this field, a major prerequisite is the ability to tune the nanorod dimensions towards optimal compatibility with electron-donating absorber materials. In this work, a water-based seeding and growth procedure is used to synthesize ZnO nanorods. The nanorod diameter is tuned either by modifying the zinc concentration of the seeding solution or by changing the concentration of the hydrothermal growth solution. The consequences of this morphological tailoring in the performance of hybrid solar cells are investigated, which leads to a new record efficiency of 0.82 % for hydrothermally grown ZnO nanorods of size 300 nm in combination with poly(3-hexylthiophene-2,5-diyl) (P3HT). This improvement is attributed to a combined effect of nanorod diameter and orientation, and possibly to a better alignment of the P3HT backbone resulting in improved charge transport.

An Evaluation of Radar Rainfall Estimates from Specific Differential Phase (2001)

Specific differential propagation phase (KDP) is examined for estimating convective rainfall in Colorado and Kansas. Estimates are made at S band with KDP alone and in combination with radar reflectivity (ZH). Results are compared to gauge observations by computing bias factors, defined as the sum of gauge-measured rainfalls divided by the sum of radar estimates at gauges reporting rainfall, and the correlation coefficient between the gauge and radar-estimated amounts. Rainfall accumulations computed from positive-only values of KDP (provided ZH ≥ 25 dBZ) yield bias factors that vary from 0.76 to 2.42 for 3 storms in Colorado and from 0.78 to 1.46 for 10 storms in Kansas. Correlation coefficients between gauge-observed and radar-estimated rainfalls are 0.76 to 0.95. When negative KDP's are included as negative rainfall rates, bias factors range from 0.81 to 3.00 in Colorado and from 0.84 to 2.31 in Kansas. In most storms, the correlation between gauge and radar rainfalls decreases slightly. In an experiment with the KDP/ZH combination, rainfall rates are computed from KDP when KDP is ≥0.4° km−1 and from ZH for KDP < 0.4° km−1 and ZH ≥ 25 dBZ. Neglect of the negative KDP's and substitution of the always positive ZH rainfall rates result in a tendency to overestimate rainfall. Bias factors are 0.63–1.46 for Colorado storms and 0.68–0.97 for Kansas storms, and correlation coefficients between gauge and radar amounts are 0.80–0.95. In yet another test with the KDP/ZH pair, rainfall estimates are computed from KDP when ZH ≥ 40 dBZ and from ZH when 25 ⩽ ZH < 40 dBZ. For this experiment, bias factors range from 0.90 to 1.91 in Colorado and from 0.88 to 1.46 in Kansas. Correlation coefficients are 0.80–0.96. Since bias factors and correlation coefficients between estimated rainfalls and gauge observations for KDP are similar to those for radar reflectivity, there was no obvious benefit with KDP rainfalls for a well-calibrated radar. Large underestimates with KDP in two storms were attributed to rainfalls dominated by small drops. In one storm, the problem was aggravated by widespread negative KDP's thought related to vertical gradients of precipitation. An advantage of KDP-derived rainfall estimates confirmed here is an insensitivity to anomalous propagation.
Platinum-Coated Nickel Nanowires as Oxygen-Reducing Electrocatalysts (2014)

Platinum (Pt)-coated nickel (Ni) nanowires (PtNiNWs) are synthesized by the partial spontaneous galvanic displacement of NiNWs, with a diameter of 150–250 nm and a length of 100–200 μm. PtNiNWs are electrochemically characterized for oxygen reduction (ORR) in rotating disk electrode half-cells with an acidic electrolyte and compared to carbon-supported Pt (Pt/HSC) and a polycrystalline Pt electrode. Like other extended surface catalysts, the nanowire morphology yields significant gains in ORR specific activity compared to Pt/HSC. Unlike other extended surface approaches, the resultant materials have yielded exceptionally high surface areas, greater than 90 m2 gPt–1. These studies have found that reducing the level of Pt displacement increases Pt surface area and ORR mass activity. PtNiNWs produce a peak mass activity of 917 mA mgPt–1, 3.0 times greater than Pt/HSC and 2.1 times greater than the U.S. Department of Energy target for proton-exchange membrane fuel cell activity.
Digital waveform analysis techniques for pixelated semiconductor detectors (2007)

A digital signal processing system for pixelated mercuric iodide and cadmium zinc telluride gamma detectors has been developed to explore the benefits of pulse analysis based on digital waveform acquisition. The system is capable of collecting 15 digital waveforms per radiation interaction event simultaneously. The precision of these measurements is enhanced through the use of digital filters optimized for unique signal features. Detailed analysis of waveforms from a set of adjacent pixels reveals energy, timing, and interaction position information. Current efforts focus on software-based techniques to characterize single and multiple pixel events including charge sharing, x-ray escape, and Compton scatter. The ability to distinguish between these events is a critical component of event reconstruction algorithms used in many radiation imaging applications.
Moisture‐Assisted Preparation of Compact GaN:ZnO Photoanode Toward Efficient Photoelectrochemical Water Oxidation (2016)

Developing strategies that can promote charge transportation in photodevices is crucial for achieving high solar energy conversion efficiency. Herein a moisture‐assisted nitridation approach is presented for the fabrication of efficient gallium‐zinc oxynitride (GaN:ZnO) photoanode with compact structure to facilitate the charge transportation. With moisture‐assisted nitridation, the charge separation efficiency and injection efficiency obtained on GaN:ZnO photoanode are significantly enhanced. Correspondingly, the photocurrent at 1.23 V vs reversible hydrogen electrode (RHE) has 18 folds improvement compared with that prepared without moisture assistance. Furthermore, via treating with HCl acid and modification with cobalt phosphate (CoPi) as a cocatalyst, state‐of‐the‐art photocurrent over 2.0 mA cm −2 is achieved on independent GaN:ZnO photoanode when bias is higher than 1.4 V vs RHE. To the best of our knowledge, this is the first paradigm of moisture‐assisted preparing oxynitride‐based photoanode. The participation of moisture is found to improve the interconnection between adjacent GaN:ZnO nanoparticles as well as that between the GaN:ZnO film and the underlying substrate. Moreover, the volatilization of Zn can be substantially suppressed due to the modulation of reaction pathway by moisture. These two factors are confirmed to be the main reasons for the enhanced charge transportation and PEC performance obtained on GaN:ZnO photoanode.
Catalytic hydroxylation of benzene to phenol with hydrogen peroxide using catalysts based on molecular sieves (2013)

Phenol is an important intermediate for the production of petrochemicals, agrochemicals and plastics. Most phenol worldwide is produced via the three-step cumene process from benzene. The disadvantages of the cumene process have stimulated the development of alternative routes to decrease energy consumption, increase the yields and avoid the explosive intermediate (cumene hydroperoxide) and the byproduct acetone. The one-step direct hydroxylation of benzene toward phenol has been extensively investigated using various oxidants such as molecular oxygen, nitrous oxide and hydrogen peroxide. But the selective production of phenol with high yields remains a challenge because phenol is more reactive toward oxidation than benzene. It is difficult to achieve high selectivity using molecular oxygen because of the high reaction temperatures and overoxidation which arise from the more active catalysts used for activating oxygen. The application of nitrous oxide is limited by the source, although the phenol selectivity and conversion can be high. Amongst the oxidants, hydrogen peroxide has obvious advantages as water is the only byproduct. In the past several decades, a variety of catalysts have been developed for the direct hydroxylation of benzene with hydrogen peroxide as the oxidant. Catalysts based on molecular sieves show outstanding catalytic performances for the reaction. This perspective article discusses the direct hydroxylation of benzene to phenol using hydrogen peroxide with catalysts based on molecular sieves, including pristine molecular sieve catalysts, transition metals incorporated molecular sieves, transition metal oxides supported on molecular sieves, complexes grafted on molecular sieves, and heteropoly acids supported on molecular sieves.

We describe the synthesis and preliminary in vitro and in vivo pharmacological tests of five endothiotetrapeptide analogues of the opioid heptapeptide dermorphin H-Tyr-D-Ala-Phe-Gly-Tyr-Pro-Ser.-NH2. The modification obtained by substituting Phet for Phe3 or Glyt for Gly4 provided further analogues with significant opioid activity.
Novel evidence‐based systemic lupus erythematosus responder index (2009)

3D ray+Born migration/inversion—Part 1: Theory (2003)

Abstract Prestack ray+Born migration/inversion can be split in two steps : the computation of common image gathers (CIGs) and their weighted stack (the migration stack). The choice of the domain for the CIGs (shot, offset, angle, etc.) has a direct impact on the resolution of the migration stack. This resolution can be studied easily in the frame of ray+Born migration/inversion theory resulting into improved migration/inversion formulas according to the acquisition geometry. This paper is devoted to this analysis in the cases of a simple 2D acquisition and of a 3D swath acquisition, both corresponding to classical data sets from the SEG/EAGE 3D overthrust experiment. We show that the migration formula originally designed for 3D marine acquisition is not adaptable to the 3D swath acquisition. Finally, we propose a new formula for this specific acquisition, which improves the resolution of the final migrated image. The relevance of this new formula is illustrated in the frame of the SEG/EAGE experiment in the companion paper.

Mapping of peanut crops in Queensland, Australia, using time-series PROBA-V 100-m normalized difference vegetation index imagery (2018)

Mapping of peanut crops is essential in supporting peanut production, yield prediction, and commodity forecasting. While ground-based surveys can be used over small areas, the development of remote-sensing technologies could provide rapid and inexpensive crop area estimates with high accuracy over large regions. Some of these recent earth observation satellite systems, such as the Project for On-Board Autonomy Vegetation (PROBA-V), have the advantage of increased spatial and temporal resolution. With a study area located in the South Burnett region, Queensland, Australia, the primary aim of this study was to assess the ability of time-series PROBA-V 100-m normalized difference vegetation index (NDVI) for peanut crop mapping. Two datasets, i.e., PROBA-V NDVI time-series imagery and the corresponding phenological parameters generated from TIMESAT data analysis technique, were classified using maximum likelihood classification, spectral angle mapper, and minimum distance classification algorithms. The results show that among all methods used, the application of MLC in PROBA-V NDVI time series produced very good overall accuracy, i.e., 92.75%, with producer and user accuracy of each class ≥78.79 % . For all algorithms tested, the mapping of peanut cropping areas produced satisfactory classification results, i.e., 75.95% to 100%. Our study confirmed that the use of finer resolution 100 m of PROBA-V imagery (i.e., relative to MODIS 250-m data) has contributed to the success of mapping peanut and other crops in the study area.
Effect of Ni addition into Co ferrite thin films for perpendicular recording media (2000)

The present article describes effects of doping Ni2+ ions into Co ferrite plated films on film structure, magnetic properties, and read/write characteristics. While thinner films are required for low noise level even in perpendicular recording media, average surface roughness Ra of the Co ferrite films increased from 4 to 6 nm with decreasing the film thickness from 100 to 50 nm. Adding Ni2+ ions had an effect on controlling the grain growth, resulting in a reduction in Ra to 3–4 nm for the 50-nm-thick films by adding a small amount of Ni2+ ions {rm[=CNi/(CCo+CNi)]=0.1}. Perpendicular coercivity Hc⊥ of the Co–Ni ferrite film at rm=0.1 was 2500 Oe, which is almost the same as that of the Co ferrite films, and Hc⊥ decreased with increasing rm. Atomic force microscope images showed that the Co–Ni ferrite films were composed of uniform and isolated grains without coagulation. As a result, a Co–Ni ferrite medium fabricated at rm=0.1 exhibited lower noise level than a Co ferrite medium without Ni addition.
