Cointegration, unbiased expectations, and forecasting in the BIFFEX freight futures market (2000)

The relationship between freight cash and futures prices is investigated using cointegration econometrics. Results illustrate that the BIFFEX futures market is unbiased, and hence efficient for the current, one, two, and quarterly contract horizons. Since the futures contract is based on an index of various shipping routes, which has undergone several changes since its inception, stability in the relationship between the spot and futures rates is investigated using rolling cointegration techniques. Results indicate that the futures contract appears to have become more efficient over time in predicting the spot rate, and that the decrease in trading volume found in the BIFFEX market is not driven by a lack of efficiency in this market. Rather, the decrease in futures trading might be attributed to the growth rate of the freight forward market. This article incorporates the long-run cointegrating relationships between cash and futures prices in a forecasting model and compares the forecasting performance of this model with several alternatives. It is found that while the futures price is the best predictor of future spot rates for the current-month contract, time-series models can outperform the futures contract at longer contract horizons. © 2000 John Wiley & Sons, Inc.

Annotated bibliography on internationalization and localization (1997)

The purpose of this article is to review some of the literature about internationalization and localization, particularly that which I have found to be useful in my own work. Over the last few years I have worked extensively in internationalization and localization in the production of shrink-wrapped packages, mostly in Quality Assurance and occasionally in project management. I keep up-to-date by subscribing to a few newsgroups, and by attending professional meetings, And I also read extensively.
My Life in Heavy Metal (review) (2002)

/ emews^Lmiií& My Life in Heavy Metal by Steve Almond Grove Press, 2002, 204 pp., $23 Readers of The Missouri Review will recognize the intense, provocative, often hilarious prose they've come to expect from Steve Almond in his debut collection. My Life in Heavy Metal tells the stories of the generation growing up and apart in the 1980s and 1990s, struggling to connect emotionallybut often connecting only sexuaUy. The title story sets the backdrop of hair bands and headbanging that is an inevitable part of the collective consciousness of men coming of age in the eighties. Everyguy David can't understand why his beautiful girlfriend, Jo, loves him; Jo can't understand David's love for heavy metal, a genre to which he ardently devotes himself when he takes ajob as a pop-music critic for a newspaper . When Almond writes of the formulaic scene of a Skid Row show, those of us who've grown up watching MTV know what's he's talking about: "When I stared down the row, I saw twenty heads banging in unison , like angry mops. These were kids lousy with the bad hormones of adolescence, humiliated by the poverty of their prospects, and this was their dance, their chance to be part of some larger phallic brotherhood ; the notes lashed their ribcages, called out to their beautiful, furious wishes." In "Geek Player/Love Slayer" (originally published in The Missouri Review), the triumphs and humiliations oflove from a woman's point of view are told with candor. The story begins, "Computer Boy swaggers over to my cube to help me open this one knucklehead email Phoenix sent me and within about, oh, two seconds, I'm ready to whip off his khakis and blow him right there." Not exactly the kind of material you'd want to read while sitting next to your grandmother on a plane flight, but while the stories have a coarse truthfulness, Almond can turn from playful seediness to truly touching moments within the same story. While the protagonist of "Geek Player" is forced to come to terms with her own lust and its consequences, this is ultimately a story of redemption , one of the few messages ofhope Almond offers in the coUection. Ultimately, beneath the stylish writing , beneath the sometimes vulgar dialogue, are real characters battling against the disUlusionment caused by a sort of generalized post-modern loss of innocence—characters who hide behind façades of detachment, flawed but fumbling for something more. It seems that no matter what they do or whom they hurt, we're stiU rooting for them to find it somewhere . (AB) The Missouri Review · 201 ...
Fabrication of two-dimensional metallodielectric quasicrystals by single-beam holography (2006)

We experimentally demonstrate a single-beam holography for creating Ag nanoparticle-embedded eight-fold quasicrystals. By adjusting the phase relation of interference beams through an optical mask, we obtain eight-fold symmetry structures with three different profiles. The structure of quasicrystals is confirmed through scanning electron microscopy and optical diffraction pattern, respectively. Furthermore, we also numerically demonstrate that the method can encode even higher symmetric structures such as the most complex 14- and 18-fold quasicrystals as well by computer simulations.
LYSOZYME AND DEFENSE PEPTIDES AS SUPPRESSORS OF PHENOLOXIDASE ACTIVITY IN <i>Galleria mellonella</i> (2014)

The prophenoloxidase (proPO) cascade supplies quinones and other reactive compounds for melanin formation, protein cross-linking, hemolymph coagulation, and killing of microbial invaders as well as parasites. The high cytotoxicity of the generated compounds requires a strict control of the activation of the proPO system and phenoloxidase (PO) activity to minimize damage to host tissues and cells. The PO activity in hemolymph of Escherichia coli challenged Galleria mellonella larvae increased, with a temporal drop 1 h after the challenge, reaching the highest level 24 h after the challenge. In the present study, a potential role of G. mellonella defense peptides and lysozyme in controlling the proPO system was investigated. The effects of purified defense peptides (anionic peptides 1 and 2, cecropin D-like peptide, Galleria defensin, proline-rich peptides 1 and 2) and lysozyme were analyzed. Four compounds, namely lysozyme, Galleria defensin, proline-rich peptide 1, and anionic peptide 2, decreased the hemolymph PO activity considerably, whereas the others did not affect the enzyme activity level. Our results indicate that these hemolymph factors could play multiple and distinct roles in the insect immune response.
Pre-Loads: Successful Mitigation of Damaging Frac Hits in the Eagle Ford (2018)

Abstract Although infill drilling and tighter well spacing have improved the production and economic return for North American Shale leases, these practices have intensified a problematic side effect often referred to as Frac Hits (Jacobs 2017). Frac hits occur when a new ‘child’ well is completed near an already producing well and the frac treatment interacts with the older parent well, usually resulting in either total loss of production or diminished producing capacity (King et al. 2017). In some fields, such as the Haynesville, frac hits have been reported to improve parent well production (Esquivel & Blasingame 2017). However, as these wells produce longer in to their life cycle, that positive impact is less certain to result in a long-term recovery improvement. In the past, the loss of the parent well was not associated with a significant loss in production compared to the new wells. However, with increasingly larger completion designs executed on wells spaced ever closer together, the impact of frac hits has grown substantially in the past few years (Daneshy 2017; Rainbolt & Esco 2018). Frac hits are not a new phenomenon in the development of North America's Shale fields. Usually first encountered by operators during the progression from Hold By Production (HBP) to infill drilling, they have been widely documented and studied over the past 6+ years. However, apart from avoiding frac hits entirely through a fully integrated field development plan, the existing industry literature does not provide a flexible, repeatable, cost effective solution to mitigating frac hits. Refracs have been discussed for parent wells next to the new infills, but economics have been difficult to justify on more recently completed wells with larger completion designs, and refracs do not address the challenge of third or higher generation infill activities where several wells are at risk of being frac hit. This document will cover the development of the frac hit mitigation technique that the authors developed in their company's Eagle Ford acreage and which is now employed as standard practice for all infill completion campaigns in both the Eagle Ford and Permian.
Development of a computer technique for the prediction of transport aircraft flight profile sonic boom signatures (1991)

A new computer technique for the analysis of transport aircraft sonic boom signature characteristics was developed. This new technique, based on linear theory methods, combines the previously separate equivalent area and F function development with a signature propagation method using a single geometry description. The new technique was implemented in a stand-alone computer program and was incorporated into an aircraft performance analysis program. Through these implementations, both configuration designers and performance analysts are given new capabilities to rapidly analyze an aircraft's sonic boom characteristics throughout the flight envelope.
Dissociation of Bovine Liver Catalase into Subunits on Acetylation (1974)

Acetylation of catalase [EC 1.11.1.6] was carried out with both N-acetylimidazole (AI) and acetic anhydride (AA). The maximal degree of acetylation of catalase was 54% with AI and 74% with AA according to the ninhydrin method. The sedimentation coefficient (s20, w) of 54% acetylated catalase was 9.3S, which indicated only a considerable unfolding of the molecule. It showed 65% activity and about 20% Teduction in α-helical conformation as compared with the native enzyme, through the conformation in the vicinity of heme groups seemed to be unchanged. Acetylation with AA to 74% caused the protein to split into two components of 9.7 and 3.6S. Each component could be isolated by sedimentation in a sucrose density gradient from 5 to 25%. The molecular weights of the two components thus obtained were estimated to be 220,000±30,000 for 9.7S and 61,000±l,000 for 3.6S by the sedimentation equilibrium method. The former was almost the same as that of native catalase and the latter was a one-fourth sized subunit. The results indicated that acetylation with AA caused partial dissociation of the catalase molecule into 1/4-sized subunits which still retained some α-helical conformation. Fluorescence analyses of tryptophanyl residues and 8-anilinonaphthalene-l-sulfonate bound to catalase indicated that the surface of the protein may be covered with hydrophilic amino acid residues. When the molecule was split into subunits by acetylation or denaturation with acid or base, the fluorescence intensity increased remarkably, suggesting that hydrophobic region(s) buried inside the molecule was exposed to the surface.

High speed signal processing with tapped dispersive SAW based delay lines (2002)

In this paper we present a new method of signal processing in chirp spread spectrum systems utilizing tapped dispersive surface acoustic wave (SAW) delay lines. The fundamentals of chirp impulse compression and its application for a reliable low cost data transmission system are described. The vulnerability by jammers is discussed and the necessity of interference suppression is shown. Our new suppression method in time and frequency, yields fast adaptive interference cancellation. Due to the implementation of SAW matched chirp filters for impulse compression, there is no necessity of synchronization for detection in the receiver. For verification the theory, simulation results and some experimental results are presented.

Dry Deposition of Polycyclic Aromatic Hydrocarbons in Ambient Air (1996)

Dry deposition and air sampling were undertaken, simultaneously, in the ambient air of an urban site and a petrochemical-industry (PCI) plant by using several dry deposition plates and PS-1 samplers from January to May 1994 in southern Taiwan. The dry deposition plate with a smooth surface was always pointed into the wind. Twenty-one polycyclic aromatic hydrocarbons (PAHs) were analyzed by a gas chromatography/mass spectrometer (GC/MSD). The dry deposition flux of total-PAHs in urban and PCI sites averaged 166 and 211 μg/m 2s˙d, respectively. In general, the PAH dry deposition flux increased with increases in the PAH concentration in the ambient air. The PAH pattern of dry deposition flux in both urban and PCI sites were similar to the pattern measured by the filter of the PS-1 sampler and completely different from the PAH pattern in the gas phase. The higher molecular weight PAHs have higher dry deposition velocities. This is due to the fact that higher molecular weight PAHs primarily associated with the particle phase are deposited mostly by gravitational settling, while the gas phase PAHs are deposited mainly by diffusion. The dry deposition velocities due to gravitational settling are much higher than those due to diffusion. When the dry-deposition-velocity ranges of gas phase PAHs were between 0.001 and 0.010 cm/s, only the lower molecular-weight PAHs—Nap and AcPy—had a significant fraction of dry deposition flux contributed by the gas phase. All the remaining higher molecular-weight PAHs had more than 94.5% of their dry deposition flux resulting from the particle phase. This is due to the fact that higher molecular weight PAHs have a greater fraction in the particle phase and the dry deposition velocities of particulates are much higher than those of the gas phase.
A comparative study of the X‐ray diffraction patterns and thermal transitions of metal soaps (1949)

Summary X‐ray diffraction patterns at room temperature for soaps of barium, calcium, and lithium were found to be characteristic for different soaps of the same cation. This is true not only for palmitates and stearates but also (with minor variations) for mixed soaps containing up to at least 50% oleate, for pure calcium oleate, and even for lithium 12‐hydroxystearate. Soaps of the same cation in mixtures approximating the composition of natural tallow fatty acids appear to form mixed crystals. The succession of phases formed on heating shows strongly the influence of the oleate in the mixture. Calcium resinates appear to crystallize imperfectly but definitely with a “head to head” arrangment of the abietate radicals in contrast to the acids which give evidence of a head to tail arrangement.
Feature selection using principal feature analysis (2007)

Dimensionality reduction of a feature set is a common preprocessing step used for pattern recognition and classification applications. Principal Component Analysis (PCA) is one of the popular methods used, and can be shown to be optimal using different optimality criteria. However, it has the disadvantage that measurements from all the original features are used in the projection to the lower dimensional space. This paper proposes a novel method for dimensionality reduction of a feature set by choosing a subset of the original features that contains most of the essential information, using the same criteria as PCA. We call this method Principal Feature Analysis (PFA). The proposed method is successfully applied for choosing the principal features in face tracking and content-based image retrieval (CBIR) problems. Automated annotation of digital pictures has been a highly challenging problem for computer scientists since the invention of computers. The capability of annotating pictures by computers can lead to breakthroughs in a wide range of applications including Web image search, online picture-sharing communities, and scientific experiments. In our work, by advancing statistical modeling and optimization techniques, we can train computers about hundreds of semantic concepts using example pictures from each concept. The ALIPR (Automatic Linguistic Indexing of Pictures - Real Time) system of fully automatic and high speed annotation for online pictures has been constructed. Thousands of pictures from an Internet photo-sharing site, unrelated to the source of those pictures used in the training process, have been tested. The experimental results show that a single computer processor can suggest annotation terms in real-time and with good accuracy.
Selectively deposited nickel film for via filling (1989)

A selective deposition process is used to fill vias in VLSI multilevel interconnection. Ni film is chosen as the via-filling material because of its compatibility with the underlying Al film. The vias are filled with a thin Pd film first and a thick Ni film. The deposited Ni film is uniform and smooth in the via regions. This film is not attacked by the plasma etch used in subsequent Al patterning; therefore, the design rule of overlapping the second metal on vias can be relaxed. The specific via resistance of this process is 4*10/sup -9/ Omega -cm/sup 2/. The via resistance increases about 30% after an exposure to 450 degrees C for 8 h.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

MALDI-TOF-MS analysis of small molecules using modified mesoporous material SBA-15 as assisted matrix (2009)

Mesoporous silica, SBA-15 was successfully functionalized with quinoline moiety, and was applied as a matrix in the MALDI-TOF-MS analysis of small molecules. The modified SBA-15 material [SBA-15-8-(3-(triethoxysilyl)propoxy) quinoline, SBA-15-8QSi] was obtained by using calcined SBA-15 and 8-hydroxy quinoline. The structure of the functionalized mesoporous material was systemically characterized by TEM, the N(2) adsorption-desorption isotherm technique and FT-IR spectra. Compared with DHB and SBA-15, SBA-15-8QSi demonstrated several advantages in the analysis of small molecules with MALDI-TOF-MS, such as less background interference ions, high homogeneity, and better reproducibility. Based on these results, the various analytical parameters were optimized. The ideal operating conditions were (1) methanol used as the dissolving solvent; (2) sample first dropping method; (3) a ratio between the analyte and the matrix of 3.5:10. Under these optimization conditions, a low detection limit (8 pmol for L-Arginine-HCl) and high reproducibility (< or = 29%) were obtained. This technique was successfully applied to the analysis of various types of small molecules, such as saccharides, amino acids, metabolites, and natural honey.
Sorafenib with interleukin-2 vs sorafenib alone in metastatic renal cell carcinoma: the ROSORC trial (2011)

The combination of sorafenib and IL-2 did not demonstrate improved efficacy vs sorafenib alone. Improvements in PFS appeared greater in patients receiving higher-dose IL-2.
Rubella-specific IgG subclass avidity ELISA and its role in the differentiation between primary rubella and rubella reinfection (1988)

An antiglobulin enzyme-linked immunosorbent assay for rubella-specific IgG1 and IgG3 was adapted to measure antibody avidity by incorporating a mild protein denaturant, diethylamine (DEA), into the serum diluent. Sera were tested at varying dilutions, both with and without DEA, if they contained sufficient specific IgG1 or IgG3. The optical density (OD) was measured and curves were plotted. The highest OD (V) was noted and halved (V/2). The distance between the OD curves at V/2 was measured as the DEA shift value. Sera were examined from people whose sera contained rubella-specific antibodies as a consequence of infection or vaccination in the distant past (24 sera), recent primary rubella (66 sera), symptomatic reinfection (11 sera) or asymptomatic reinfection (64 sera). For specific IgG1 the DEA shift value was less than 0.6 for cases of rubella in the distant past, compared with greater than 0.8 for the first month after primary infection. The maximum DEA shift value for the sera from cases of reinfection was 0.65. No serum from cases of rubella in the distant past contained sufficient specific IgG3 to estimate avidity. The sera collected within 1 month of onset of primary rubella gave DEA shift values greater than 0.7 compared with sera from reinfections, which gave DEA shift values less than 0.6, except for two sera from a case of symptomatic reinfection. Thus the assessment of specific IgG subclass avidity is of value in differentiating serologically primary rubella from reinfection.
Centralized Binary Patterns Embedded with Image Euclidean Distance for Facial Expression Recognition (2008)

The existing local binary pattern (LBP) operators have three disadvantages: (1) They produce rather long histograms, which slow down the recognition speed especially on large-scale face database; (2) Under some certain circumstance, they miss the local structure as they don't consider the effect of the center pixel; (3) The binary data produced by them are sensitive to noise. Aiming at these problems, we proposed centralized binary pattern (CBP) operator. CBP operator has several advantages: (1) It reduces significantly the histograms' dimensionality by comparing pairs of neighbors in the operator; (2) It considers the center pixel point's effect and gives it the largest weight, thus improving discrimination; (3) By modifying the sign function of existing LBP operator, it decreases the white noise's influence on face images. Moreover, for the purpose of improving the robustness to small perturbation (deformation) of expressional images, we introduced image Euclidean distance (IMED) and embedded it in CBP. Experiments on two well-known facial expression databases demonstrate that the proposed method outperforms other modern approaches and show that IMED can enhance the performance of CBP in facial expression recognition.
