Second‐look arthroscopic findings of 208 patients after ACL reconstruction (2006)

The aim of this study is to report the arthroscopic subjective findings of reconstructed anterior cruciate ligament (ACL) with good clinical outcome. Graft used for reconstruction was either patella bone-tendon-bone (PBTB) autograft or hamstring tendon [quadrupled semitendinous and gracilis tendon (QSGT)] autograft. From March 1997 to September 2003, among 716 ACL reconstructions 209 knees (208 patients) were available for second-look arthroscopy at a mean 21.2-month (range, 14-70 months) postoperative period. The second-look arthroscopy focused on the evaluation of (1) continuity of the reconstructed ACL graft, (2) subjective graft tension using a probe, (3) the extent of synovial coverage, (4) the prevalence of cyclops or cyclops-like lesion, and (5) bony change after notchplasty. Patellar tendon autograft was used in 80 knees, hamstring tendon autograft in 129 knees. Just prior to second-look arthroscopy two objective clinical evaluations, KT-2000 arthrometer and Lysholm knee score, were performed to verify good clinical outcomes. A comparison between the hamstring tendon group and the patella tendon group, hamstring group showed slightly better results in Lysholm knee scores and KT-2000 arthrometer but there were no statistically significant differences (p>0.05). Undetected partial graft tear was seen in 21 knees (10%). With regard to graft tension, a total of 181 grafts (87%) showed normal tension and 28 (13%) showed slight lax tension. The overall synovial coverage was poor in nine (4%) knees. The synovial coverage was slightly better in the hamstring tendon group. A total of 45 knees (21.5%) showed cyclops-like lesion in variable sizes and locations. Reformation of the notch was seen in 85 knees (40%). In conclusion, the findings of second-look arthroscopy of reconstructed ACL in good clinical outcome patients showed approximately 10% partial graft tear, 5% poor synovial coverage, 20% cyclops-like lesion, and 40% some notch reformation.
Relationship between Fatty Acids of Adipose Tissue and Plasma Cholesterol (1975)

The fatty acid composition of adipose tissue from normal and hypercholesterolemic men and women was studied. We found a difference in the fatty acid composition between both sexes. A decrease in linoleic acid was found in hypercholesterolemic men, while there was an increase in palmitic and totally saturated acids in women. A decrease in total monounsaturated and in monounsaturated/saturated ratio was also found in women.
The <i>négritude</i> movement (1986)

In 1927 by a riverside in Madagascar a twenty-six-year-old Malagasy poet composed a sonnet comparing the water's course to his own growing skill in the language of his French masters. If only, he wrote, his lines might aspire to the grace and undulating curve of the river bank itself:
The Lifecycles of Apps in a Social Ecosystem (2015)

Apps are emerging as an important form of on-line content, and they combine aspects of Web usage in interesting ways --- they exhibit a rich temporal structure of user adoption and long-term engagement, and they exist in a broader social ecosystem that helps drive these patterns of adoption and engagement. It has been difficult, however, to study apps in their natural setting since this requires a simultaneous analysis of a large set of popular apps and the underlying social network they inhabit. In this work we address this challenge through an analysis of the collection of apps on Facebook Login, developing a novel framework for analyzing both temporal and social properties. At the temporal level, we develop a retention model that represents a user's tendency to return to an app using a very small parameter set. At the social level, we organize the space of apps along two fundamental axes --- popularity and sociality --- and we show how a user's probability of adopting an app depends both on properties of the local network structure and on the match between the user's attributes, his or her friends' attributes, and the dominant attributes within the app's user population. We also devolop models that show the importance of different feature sets with strong performance in predicting app success.
Some etch properties of doped and undoped silicon oxide films formed by atmospheric pressure and plasma-activated chemical vapor deposition (1985)

Silicon oxide films formed using two different chemical vapor deposition (CVD) techniques have been characterized by selected etching properties, both in dry (plasma) etching and in wet (chemical) etching. Dry etching was accomplished using CHF3+O2 in a reactive ion etching (RIE) system. The films investigated are undoped silicon oxide, phosphorus-doped silicon oxide at 4 mol % P2O5, and phosphorus-doped silicon oxide at 9.5 mol % P2O5. The effects of densification, i.e., thermal treatments carried out at 900 °C in an inert atmosphere (N2) and at 920 °C in steam, are discussed in detail. A decrease in etch rate is observed and considered to be an indication of the structural changes that lead to less porous and more stable films.
The effects of pentazocine, a kappa agonist, in patients with mania (2007)

Past evidence suggests that activation of kappa opiate receptors may lower mood. However, kappa agonists may also induce psychotomimetic symptoms. We tested the effects of the kappa agonist pentazocine in patients in the manic phase of bipolar disorder to determine if pentazocine might reduce symptoms of mania without worsening psychosis. In an open-label, add-on, single-day acute-dose study, ten in-patients with bipolar disorder, type 1, hospitalized for mania received two 50 mg doses of pentazocine 2 h apart. Symptoms of mania were reduced 1 h after each dose, 44% after the first dose and 41% 1 h after the second dose (F=3.69, p=0.01). No adverse effects, including psychotomimetic effects were observed or reported. Sedation was minimal. Further study of pentazocine and other kappa agonists in mania seems warranted.
Elastic Property Prediction of Single-Walled Carbon Nanotube Buckypaper/Polymer Nanocomposites: Stochastic Bulk Response Modeling (2011)

In this study, we investigated the statistical relationship between nanostructure variations of carbon nanotube buckypaper-polymer (BPP) composites and their resulting elastic properties. A statistical simulation was developed to predict the elastic properties of a single-layer BPP lamina and extrapolated to the resultant bulk composite part. The stochastic characteristics of BPP composite nanostructure were quantified from experimental observations and used to generate the input for each simulation set performed. The Mori-Tanaka method was used to calculate the stiffness tensor within the buckypaper-polymer region, and a Monte-Carlo simulation was applied to generate the probability distribution for the effective stiffness tensor within each BPP lamina. Classical laminate theory was then employed to predict the effective elastic response for a multi-layered BPP composite laminate. The theoretical predictions were compared with experimental data, and the resulting trends for the effective tensile modulus between experimental and theoretical corresponded well with each other.

Mechanistic and Kinetic Studies of the Ring Opening Metathesis Polymerization of Norbornenyl Monomers by a Grubbs Third Generation Catalyst (2019)

The mechanism of ring-opening metathesis polymerization (ROMP) for a set of functionalized norbornenyl monomers initiated by a Grubbs third generation precatalyst [(H<sub>2</sub>IMes)(pyr)<sub>2</sub>(Cl)<sub>2</sub>Ru═CHPh] was investigated. Through a series of <sup>12</sup>C/<sup>13</sup>C and <sup>1</sup>H/<sup>2</sup>H kinetic isotope effect studies, the rate-determining step for the polymerization was determined to be the formation of the metallacyclobutane ring. This experimental result was further validated through DFT calculations showing that the highest energy transition state is metallacyclobutane formation. The effect of monomer stereochemistry (exo vs endo) of two types of ester substituted monomers was also investigated. Kinetic and spectroscopic evidence supporting the formation of a six-membered chelate through coordination of the proximal polymer ester to the Ru center is presented. This chelation and its impact on the rate of polymerization are shown to vary based on the monomer employed and its stereochemistry. The combination of this knowledge led to the derivation of a generic rate law describing the rate of polymerization of norbornene monomers initiated by a Grubbs third generation catalyst.
Continuous Infusion Epidural Analgesia in Parturients Receiving Bupivacaine, Chloroprocaine, or Lidocaine-Maternal, Fetal, and Neonatal Effects (1984)

The effects of epidural analgesia for labor and delivery using a continuous infusion technique on fetal heart rate, uterine activity, maternal blood pressure, Apgar scores, neonatal acid-base status, and the Neurologic and Adaptive Capacity Scoring System were studied in 61 parturients. Group I (n = 23) received initial test and therapeutic doses of 2 and 6 ml of 0.5% bupivacaine followed by an infusion of 0.125% at a rate of 14 ml/hr. Group II (n = 19) received 2 and 6 ml of 2% chloroprocaine followed by an infusion of 0.75% at a rate of 27 ml/hr. Group III (n = 19) received 2 and 6 ml of 1.5% lidocaine followed by an infusion of 0.75% at a rate of 14 ml/hr. None of the three local anesthetics used had any significant effect on baseline fetal heart rate or uterine activity. In cases in which monitoring of fetal heart rate was both technically satisfactory and continuous, late and variable decelerations in fetal heart rate were seen in 10 of 17, 3 of 18, and 2 of 19 of the fetuses in groups I, II, and III, respectively. The incidence was significantly higher in group I than in groups II or III (P less than 0.05). Apgar scores and neonatal acid-base status were equally good in all three groups. Neurologic and adaptive capacity scores did not differ among the three groups of neonates, nor did any of the neonates in the three groups score lower than a control group of 19 neonates whose mothers did not receive any analgesia or medications for labor and delivery.(ABSTRACT TRUNCATED AT 250 WORDS)
Menstrual problems and health-seeking behaviour in Hong Kong Chinese girls. (2009)

The prevalence of menstrual problems in Hong Kong Chinese girls is high and causes significant disruption to their school and daily activities. However, only a minority seek medical advice.
Integrated arrays of 1.3-μm buried-crescent lasers (1983)

Arrays of five InGaAsP buried-cresent large-optical-cavity lasers operating at 1.3 μm are described. The monolithically integrated arrays have threshold as low as 60 mA, external quantum efficiencies η≊55%, and operate in the fundamental transverse mode up to 50 mW per facet at room temperature. Despite the very close center to center spacing of 8 μm, no electrical or optical interaction between lasers has been observed.
Involvement of the Neurotensin Receptor-3 in the Neurotensin-Induced Migration of Human Microglia (2003)

Microglia motility plays a crucial role in response to lesion or exocytotoxic damage of the cerebral tissue. We used two in vitro assays, a wound-healing model and a chemotaxis assay, to show that the neuropeptide neurotensin elicited the migration of the human microglial cell line C13NJ by a mechanism dependent on both phosphatidylinositol 3-kinase (PI 3-kinase) and mitogen-activated protein (MAP) kinase pathways. The effect of neurotensin on cell migration was blocked by the neurotensin receptor-3 propeptide, a selective ligand of this receptor. We demonstrate, by using RT-PCR, photoaffinity labeling, and Western blot analysis, that the type I neurotensin receptor-3 was the only known neurotensin receptor expressed in these microglial cells and that its activation led to the phosphorylation of both extracellular signal-regulating kinases 1/2 and Akt. Furthermore, the effect of neurotensin on cell migration was preceded by a profound modification of the F-actin cytoskeleton, particularly by the rapid formation of numerous cell filopodia. Both the motility and the filopodia appearance induced by neurotensin were totally blocked by selective inhibitors of MAP kinases or PI 3-kinase pathways. This demonstrates that the neurotensin receptor-3 is functional and mediates the migratory actions of neurotensin.
Dielectric cavity raises YAG efficiency (1975)

The benefits of using dielectric coated quartz cavities instead of metal- coated cavities are discussed. In range finder applications, advantages include high efficiency, long term reliability and operation, light weight and compactness, durability in extreme environments, and the possibility of operating without liquid cooling. For laser-fusion research using yttrium-aluminum garnet/ neodymium: glass rods, there would be no solarization, very low loss due to depumping and lateral lasing, and rejection of distortion-causing heat. In flash lamp pumped HF, DF and iodine lasers, narrow-band pumping makes it possible to reject unwanted radiation such as uv, ir, and the lasing wavelength itself, thereby making such lasers more feasible and efficient.

Spatial temperature gradient capillary electrophoresis for DNA mutation detection (2001)

A continuous spatial temperature gradient was established in capillary electrophoresis by using a simple temperature control device. The temperature profile along the capillary was predicted by theoretical calculations. A nearly linear spatial temperature gradient was established and applied to DNA mutation detection. By spanning a wide temperature range, it was possible to perform simultaneous heteroduplex analysis for various mutation types that have different melting temperatures.
Automating Music Production with Music Information Retrieval (2013)

Prior research in the field of Music Information Retrieval has yielded techniques for extracting musical information from digital audio, and made it possible to analyze human music production computationally. I hypothesize that a computer can be programmed to produce output similar to that of a musical artist on two production tasks performed by disk jockeys. The first, “mixing,” aims to create seamless transitions between songs in a playlist. The second, “mashup” creation, aims to overlay multiple similar tracks to create a new combined song. To automate these tasks, I first created example sets of my own mixes and mashups, and looked for patterns and relationships in the audio analysis data from the public music analysis API provided by The Echo Nest, Inc. I used my findings to write Python scripts that automatically perform the mixing or mashing tasks on any input audio files. The software was udged by a sample of individuals for its ability to produce output similar to that of a human DJ. Preliminary results support the claim that automatic music production processes can be convincing, but also show how programs perform poorly when processing unexpected input, suggesting that tasks are most easily replicated within specific, predefined artistic styles.
The effect of specific catalysts on the reactions of the steam-carbon system (1952)

Abstract The reactions of the steam-carbon system have been studied by the static method at 750° C using extracted coconut charcoal to which iron, sodium, calcium and aluminium were added separately. The steam-carbon reaction is catalyzed chiefly by sodium, the carbon dioxide-carbon reaction by iron and sodium, while the heterogeneous oxidation of carbon monoxide by steam is enhanced by all the additions except aluminium. As required by the electronic theory of catalysis, the general course of the gasification of the carbon is found to be unaltered. Side reactions of the gases with the additions tend, however, to obscure changes in the rates of the individual steps, but give useful information about the composition of the catalysts under working conditions. The question of how the catalysts for the oxidation of carbon fulfil the role assigned to them by the electronic theory is discussed in the light of these results. An explanation is suggested in terms of the probable non-stoichiometric character of the atomic layers in closest contact with the carbon.
PCR detection of seven virulence and toxin genes of Campylobacter jejuni and Campylobacter coli isolates from Danish pigs and cattle and cytolethal distending toxin production of the isolates (2003)

The high prevalence of seven virulence and toxin genes demonstrated that these putative pathogenic determinants are widespread among Campylobacter isolates from pigs and cattle. Campylobacter coli isolates from pigs produced much higher CDT titres compared with C. coli isolates from other sources suggesting that C. coli may be particularly adapted to or associated with this species.
An in vitro method using vascular smooth muscle cells to study the effect of compounds on cell proliferation and intracellular lipid accumulation. (1993)

Primary cultures of vascular smooth muscle cells (SMC) were incubated with hyperlipidemic rabbit serum (HLRS) to produce intracellular lipid accumulation. Cultures were exposed to different concentrations of the test compounds and their effects upon cell proliferation and intracellular lipid accumulation were measured. The in vitro results obtained with different Ca2+ antagonists, a HMG-CoA reductase inhibitor and other hypolipidemic substances showed a strong correlation with the in vivo activities of these compounds, suggesting that cultured SMC may be a useful initial in vitro model to detect new chemical entities active upon atherosclerosis related parameters.
Mapping Robinia Pseudoacacia Forest Health Conditions by Using Combined Spectral, Spatial, and Textural Information Extracted from IKONOS Imagery and Random Forest Classifier (2015)

The textural and spatial information extracted from very high resolution (VHR) remote sensing imagery provides complementary information for applications in which the spectral information is not sufficient for identification of spectrally similar landscape features. In this study grey-level co-occurrence matrix (GLCM) textures and a local statistical analysis Getis statistic (Gi), computed from IKONOS multispectral (MS) imagery acquired from the Yellow River Delta in China, along with a random forest (RF) classifier, were used to discriminate Robina pseudoacacia tree health levels. Specifically, eight GLCM texture features (mean, variance, homogeneity, dissimilarity, contrast, entropy, angular second moment, and correlation) were first calculated from IKONOS NIR band (Band 4) to determine an optimal window size (13 × 13) and an optimal direction (45°). Then, the optimal window size and direction were applied to the three other IKONOS MS bands (blue, green, and red) for calculating the eight GLCM textures. Next, an optimal distance value (5) and an optimal neighborhood rule (Queen’s case) were determined for calculating the four Gi features from the four IKONOS MS bands. Finally, different RF classification results of the three forest health conditions were created: (1) an overall accuracy (OA) of 79.5% produced using the four MS band reflectances only; (2) an OA of 97.1% created with the eight GLCM features calculated from IKONOS Band 4 with the optimal window size of 13 × 13 and direction 45°; (3) an OA of 93.3% created with the all 32 GLCM features calculated from the four IKONOS MS bands with a window size of 13 × 13 and direction of 45°; (4) an OA of 94.0% created using the four Gi features calculated from the four IKONOS MS bands with the optimal distance value of 5 and Queen’s neighborhood rule; and (5) an OA of 96.9% created with the combined 16 spectral (four), spatial (four), and textural (eight) features. The most important feature ranked by RF classifier was GLCM texture mean calculated from Band 4, followed by Gi feature calculated from Band 4. The experimental results demonstrate that (a) both textural and spatial information was more useful than spectral information in determining the Robina pseudoacacia forest health conditions; and (b) the IKONOS NIR band was more powerful than visible bands in quantifying varying degrees of forest crown dieback.
End-Point Immobilization of Recombinant Thrombomodulin via Sortase-Mediated Ligation (2012)

We report an enzymatic end-point modification and immobilization of recombinant human thrombomodulin (TM), a cofactor for activation of anticoagulant protein C pathway via thrombin. First, a truncated TM mutant consisting of epidermal growth factor-like domains 4-6 (TM(456)) with a conserved pentapeptide LPETG motif at its C-terminal was expressed and purified in E. coli. Next, the truncated TM(456) derivative was site-specifically modified with N-terminal diglycine containing molecules such as biotin and the fluorescent probe dansyl via sortase A (SrtA) mediated ligation (SML). The successful ligations were confirmed by SDS-PAGE and fluorescence imaging. Finally, the truncated TM(456) was immobilized onto an N-terminal diglycine-functionalized glass slide surface via SML directly. Alternatively, the truncated TM(456) was biotinylated via SML and then immobilized onto a streptavidin-functionalized glass slide surface indirectly. The successful immobilizations were confirmed by fluorescence imaging. The bioactivity of the immobilized truncated TM(456) was further confirmed by protein C activation assay, in which enhanced activation of protein C by immobilized recombinant TM was observed. The sortase A-catalyzed surface ligation took place under mild conditions and occurs rapidly in a single step without prior chemical modification of the target protein. This site-specific covalent modification leads to molecules being arranged in a definitively ordered fashion and facilitating the preservation of the protein's biological activity.
Exposure control for HDR video (2014)

This paper proposes an algorithm for determining the exposure times for High Dynamic Range (HDR) video by adapting them to the current lighting. Due to the limited capability of the sensor used, only two exposures per frame can be taken. For each image, the histogram for the exposure time of the other image is estimated. When this histogram is subtracted from the original, the result can be used to adjust the exposure time to the current lighting situation by standard exposure control algorithms. The subtraction removes the dynamic range already covered by the other image, thus the exposure time can be optimized for the residual dynamic range. The algorithm has been compared with state-of-the-art algorithms for HDR imaging. It is proven to have comparable results in mean squared error to a ground truth gained from real-world data. Furthermore this algorithm is capable of running during the capturing process of a video, since it doesn't require additional exposures than those already taken.
