Collecting Electrospun Nanofibers with Patterned Electrodes (2005)

Electrospinning is a simple, versatile, and useful technique for fabricating nanofibers from a rich variety of functional materials. The nanofibers are usually collected as nonwoven mats, in which the fibers are randomly oriented. We have recently demonstrated that the nanofibers can be uniaxially aligned by introducing an insulating gap into the conductive collector. To elucidate the mechanism of alignment, we have systematically studied the effect of the area and geometric shape of the insulating gap on the deposition of fibers. By modeling the electrostatic forces acting on the fiber, it was established that the fibers tended to be oriented along a direction such that the net torque of electrostatic forces applied to the two ends of a discrete segment of the fiber were minimized. By varying the design of electrode pattern, it was possible to control both alignment and assembly of the electrospun nanofibers.
An Analysis of the Service Quality and Satisfaction Perceived by Users and Librarians on the Foreign Research Information Center (2012)

이 연구는 외국학술지지원센터의 이용자와 상호대차담당자들을 대상으로 외국학술지지원센터에서 제공하는 서비스에 대한 품질과 고객만족도에 대한 인식을 조사 분석하였다. 외국학술지지원센터의 자체이용자, 최종이용자, 상호대차담당자의 서비스품질 지각과 고객만족도는 상당히 높은 것으로 나타났다. 자체 이용자와 최종이용자간에 만족도와 충성도, 서비스품질에 대한 지각에서 차이가 있는지를 분석한 결과, 자체 이용자가 최종이용자보다 만족도 관련 6개 항목, 충성도 관련 1개 항목, 서비스품질관련 7개 항목에서 통계적으로 유의하게 높은 것으로 나타났다. 자체이용자와 최종이용자에 대한 구조방정식 모형을 설정하고 검증한 결과, 두 모형 모두 적합한 것으로 나타났다. 자체이용자와 최종이용자 양 집단에서 만족도에 유의한 영향을 미치는 요인은 원문복사의 신청 성공률과 제공 자료의 전반적인 상태를 포함한 자료자체인 것으로 나타났다. This study is to investigate and analyze the service quality and satisfaction perceived by users and librarians of the Foreign Research Information Center (FRIC). The survey results reveal that three groups of in-campus (internal) user group, external user group and interlibrary loan librarian group has highly perceived the service quality and satisfaction of the FRIC. Two user groups have statistically significant different perceptions on the service quality, loyalty, and satisfaction. Internal user group perceived more highly than external user group, in 6 items of satisfaction, 1 item of loyalty, and 7 items of service quality. Structural equation models of satisfaction and loyalty on two user groups were proved to be appropriate. Material factor including success rate of copied text and general physical status of the copy influences significantly on the user satisfaction in both groups.
A two year trial of low protein, low arginine diets or vitamin B6 for patients with gyrate atrophy. (1982)

Four patients with gyrate atrophy on low protein (20-35 g/day), low arginine diets and one on vitamin B6 (300 mgm/day) have maintained their plasma ornithine concentrations in the range of 30-60% of pre-therapeutic trial levels for about two years. After two years, three of the five patients have shown no significant change in Snellen visual acuity, visual fields, final dark-adapted thresholds or full-field electroretinograms. All five patients have shown slight enlargement of areas of chorioretinal atrophy in the midperiphery. These patients continue on low protein, low arginine diets or on vitamin B6 to determine whether any reduction in the hyperornithinemia will result in stabilization of retinal function.
Optical absorption from polarons in a model of polyacetylene (1983)

We present a theoretical calculation, within a continuum electron-phonon-coupled model, of the optical absorption due to polarons in polyacetylene [${(\mathrm{CH})}_{x}$]. Our results can be applied to both trans- and cis-${(\mathrm{CH})}_{x}$, as well as potentially to other polymers (polypyroles, polyparaphenylenes) in which polarons are present. We establish that the essential signature of polaron absorption is the existence of three separate absorption peaks in the gap with qualitatively different features. For trans-${(\mathrm{CH})}_{x}$, we compare and contrast this structure with that from the kink solitons, which are expected to dominate the optical absorption at all but the lowest doping levels. For cis-${(\mathrm{CH})}_{x}$ and related polymers, we discuss polaron (and multipolaron) absorption and the relation of polarons to possible excitons in these materials. Finally, we evaluate briefly the existing experimental situation regarding optical absorption in polyacetylene and indicate possible future experiments that could confirm the existence of polarons in ${(\mathrm{CH})}_{x}$ and similar polymers.
GaAs multilayer p+-i homojunction far-infrared detectors (1997)

A molecular beam epitaxy grown wavelength tunable GaAs p+-i homojunction interfacial work-function internal photoemission far-infrared detector is developed. The multilayer (p+-i-p+-i-…) detector structures consist of 2, 5, and 10 emitter layers. Experimental results are explained in terms of the number of emitter layers and the doping concentrations of the emitter layer. A detector with 10 multilayers and an emitter layer doping concentration (Ne) of 3×1018 cm−3 shows a current responsivity of 2 A/W, an effective quantum efficiency of 9.2% (at 26.3 μm) with a cutoff wavelength of 85 μ and the noise equivalent power of 2.18×10−12 W/Hz at 4.2 K.
Enhance the Word Vector with Prosodic Information for the Recurrent Neural Network Based TTS System (2016)

Word embedding, which is a dense and low-dimensional vector representation of word, is recently used to replace of the conventional prosodic context as an input feature to the acoustic model of a TTS system. However, these word vectors trained from text data may encode insufficient information related to speech. This paper presents a post-filtering approach to enhance the raw word vectors with prosodic information for the TTS task. Based on a publicly available speech corpus with manual prosodic annotation, a post-filter can be trained to transform the raw word vectors. Experiment shows that using the enhanced word vectors as an input to the neural network-based acoustic model improves the accuracy of the predicted F0 trajectory. Besides, we also show that the enhanced vectors provide better initial values than the raw vectors for error back-propagation of the network, which results in further improvement.
Comparison of efficacies between live and killed probiotics in children with lactose malabsorption. (2010)

The objective of this study was to determine the efficacy of live and killed probiotics to decrease the presence of hydrogen using the breath hydrogen test (BHT). This pretest-posttest control group design single blinded randomized study was performed in 5 government elementary schools in Tuminting subdistrict, Manado, Indonesia from March to May 2008. The study for inclusion as subjects consisted of healthy 10-12 year old children with heights and weights within normal limits using the Centers for Disease Control (CDC) criteria whose BHT was 220 parts per million (ppm), indicating lactose malabsorption. One hundred thirty children were screened, 86 met criteria, 43 children were randomized into two groups. Thirty-nine children who were given live probiotic and 40 children who were given killed probiotic completed the study. There was a significant difference when comparing the BHT results before and 120 minutes after giving probiotic for the children taking both the live and the killed probiotic (p < 0.001). When the children taking the live and killed probiotics were compared, there was no difference in the BHT at 120 minutes of probiotic (p = 0.453) by t-test. The administration of live or killed probiotic for 2 weeks can decrease the results of a BHT in children with lactose malabsorption. No adverse reactions attributable to treatment were noted.
Polypeptide variants of beta-arrestin and arrestin3 (1993)

Retinal arrestin (S-antigen) inactivates the phototransduction cascade by binding to light-activated phosphorylated rhodopsin and thereby "arresting" coupling to the G protein transducin. beta-Arrestin (beta arr), a ubiquitous arrestin homolog, acts analogously to desensitize the beta 2-adrenergic receptor by disrupting Gs receptor interaction. In an attempt to identify additional "arrestins" which might regulate the multitude of G protein-coupled receptors, we have isolated two bovine brain cDNAs which encode polypeptide variants of an arrestin homolog which we have designated arrestin3 (arr3). The open reading frames of these two cDNAs are identical except that the long form, arr3L, contains an 11-amino-acid insert between residues 361 and 362. Arr3 is more closely related to bovine beta arr (78% identity) than to bovine visual arrestin (56% identity). Polymerase chain reaction amplification of RNA and immunoblotting of lysates with an arr3-specific antibody suggest that the short form, arr3S, is the major form of arr3 in all bovine tissues and that it is most abundant in the spleen. Furthermore, polymerase chain reaction amplification of beta arr mRNA indicates that in several tissues (lung, liver, spleen, and pituitary), the major form of beta arr lacks 8 amino acids which are present in brain beta arr. Immunoblotting with an antibody which recognizes beta arr and arr3 with equal sensitivity demonstrates that beta arr (either the long or the short polypeptide) is the major arrestin in all (non-photoreceptor bearing) tissues examined. These observations suggest that in some tissues, as many as four arrestin homolog variants may play a role in the regulation of G protein-coupled receptors.
An Energy Saving Scheme for Multilane-Based High-Speed Ethernet (2012)

In this paper, we propose a scheme for partially dynamic lane control for energy saving in multilane-based high-speed Ethernet. In this scheme, among the given transmission lanes, at least one lane is always operating, and the remaining lanes are dynamically activated to alleviate the network performance in terms of queuing delay and packet loss in the range of acceptance. The number of active lanes is determined by the decision algorithm based on the information regarding traffic and queue status. The reconciliation sublayer adjusts the transmission lane with the updated number of lanes received from the algorithm, which guarantees no processing delay in the media access control layer, no overhead, and minimal delay of the exchanging control frames. The proposed scheme is simulated in terms of queuing delay, packet loss rate, lane changes, and energy saving using an OPNET simulator. Our results indicate that energy savings of around 55% (or, when the offered load is less than 0.25, a significant additional savings of up to 75%) can be obtained with a queuing delay of less than 1 ms, a packet loss of less than 10−4, and a control packet exchange time of less than 0.5 μs in random traffic.
[Significance of scanning electron microscopy observations on cellular reactions in the biological evaluation of endoprosthetic materials]. (1987)

In a scanning electron microscopic study there are described the adhesion, spreading and formation of confluent monolayers from fibroblasts and epithelioid cells on Al2O3-ceramics and cobalt-basis-alloys in relation to vitreous carbon and glass. The morphogenetic reactions of cultured cells were not significantly different in pattern, behaviour and kinetics on various biomaterials. The cells adhered, spread, migrated and proliferated on the surface of biomaterials to be tested. This allows the conclusion that this implant material is compatible with cells. The variability of properties and susceptibility of cultured cells were discussed as a criterion for biocompatibility of implant materials in preclinical test.

Omental herniation. An unusual fetal complication of intrauterine transfusion. (1976)

Amniocenteses in an Rh-sensitized woman revealed the need for intrauterine transfusion to improve fetal status. Following delivery of the infant by cesarean section 7 weeks later, herniation of a segment of omentum through the anterior abdominal wall was noted. The injury was due to needle puncture during the intrauterine transfusion. The injury was repaired, and the infant recovered.
Tissue distribution of antileukoprotease and lysozyme in humans. (1989)

We studied the distribution of the proteinase inhibitor antileukoprotease (ALP) and lysozyme (LSZ) in normal human tissues by use of an immunohistochemical technique. ALP could be demonstrated in a variety of healthy tissues, generated by secretory cells in lacrimal, respiratory, proximal digestive, and genital glands, but not in the urinary tract, endocrine glands, or the hematological system. In lung, part of the non-ciliated cell population in membranous bronchiolar epithelium, as well as in respiratory bronchioles, stained positively for the inhibitor. The distribution of ALP and LSZ was parallel in most but not all of the tissues examined. The distribution of ALP around most of the external orifices of the human body is discussed in relation to its possible local physiological role in defense against inflammatory reactions. The widespread parallel distribution of LSZ, a bacteriolytic agent, suggests a complementary role to ALP in local defense.

Stimulation of autophagy reduces neurodegeneration in a mouse model of human tauopathy (2012)

The accumulation of insoluble proteins is a pathological hallmark of several neurodegenerative disorders. Tauopathies are caused by the dysfunction and aggregation of tau protein and an impairment of cellular protein degradation pathways may contribute to their pathogenesis. Thus, a deficiency in autophagy can cause neurodegeneration, while activation of autophagy is protective against some proteinopathies. Little is known about the role of autophagy in animal models of human tauopathy. In the present report, we assessed the effects of autophagy stimulation by trehalose in a transgenic mouse model of tauopathy, the human mutant P301S tau mouse, using biochemical and immunohistochemical analyses. Neuronal survival was evaluated by stereology. Autophagy was activated in the brain, where the number of neurons containing tau inclusions was significantly reduced, as was the amount of insoluble tau protein. This reduction in tau aggregates was associated with improved neuronal survival in the cerebral cortex and the brainstem. We also observed a decrease of p62 protein, suggesting that it may contribute to the removal of tau inclusions. Trehalose failed to activate autophagy in the spinal cord, where it had no impact on the level of sarkosyl-insoluble tau. Accordingly, trehalose had no effect on the motor impairment of human mutant P301S tau transgenic mice. Our findings provide direct evidence in favour of the degradation of tau aggregates by autophagy. Activation of autophagy may be worth investigating in the context of therapies for human tauopathies.
Study of the analgesic effects of galanthamine, a cholinesterase inhibitor. (1983)

The effects of galanthamine, an alkaloidal anticholinesterase agent whose chemical structure bears similarity to codeine, was studied in various animal and isolated organ tests. Antinociceptive activity of galanthamine given subcutaneously was detected and compared to physostigmine and morphine in the rat hot plate test. Naloxone partially blocked the effect of galanthamine but not that of physostigmine. Both cholinesterase inhibitors provided analgesia in the mouse acetic acid writhing test. They potentiated the effect of morphine in the rat hot plate test but inhibited the barbiturate anaesthesia potentiation of morphine in the rat. While galanthamine provided analgesia in the intact animal, it failed to produce opiate-like activity in such isolated organs as longitudinal muscle strip of the guinea-pig ileum, mouse vas deferens, and cat nictitating membrane.
Laser shock cleaning of inorganic micro and nanoscale particles (2003)

A new dry cleaning technology: laser-induced shock cleaning has been applied to remove the submicron particles (including post-CMP (chemical-mechanical polishing)) slurries from silicon wafer surfaces. The cleaning effectiveness of the new technology was evaluated quantitatively using a laser surface scanner. The results show that most of the silica particles on the wafer surface were removed after exposure to the laser-induced shock waves. The average removal efficiency of the particles was over 99%. The results show that cleaning efficiency is strongly dependent on a gap distance between laser focus point and the wafer surface and that a suitable control of the gap is crucial for the successful removal of the particles. In addition, this new technique was also applied successfully to the removal of the post-CMP slurries from polished patterned wafers.
Synthesis and properties of resin for adsorption of oil fume (2011)

Porous resins for adsorption of oil fume were prepared via suspension polymerization.The effects of crosslinking degree,components and the dosage of porogen agent on the properties for adsorption of oil fume were investigated.The results showed that the optimum synthesis condition were 10 parts by weight of DMA,90 parts by weight of TRIM,90 parts by weight of toluene,10 parts by weight of n-heptane.The adsorption amount of porous resin reached to 0.305g/g.Langmuir and Freundlich models were used to correlate the experimental data,respectively.Additionally,the mechanism of adsorption for oil fume was discussed.The results showed that the experimental data were found to fit well by Langmuir model,which indicated that the adsorption process mainly based on monolayer adsorption and pore-filling was the dominating mechanism for oil fume adsorption.
An Efficient Method for Antenna Design Optimization Based on Evolutionary Computation and Machine Learning Techniques (2013)

In recent years, various methods from the evolutionary computation (EC) field have been applied to electromagnetic (EM) design problems and have shown promising results. However, due to the high computational cost of the EM simulations, the efficiency of directly using evolutionary algorithms is often very low (e.g., several weeks' optimization time), which limits the application of these methods for many industrial applications. To address this problem, a new method, called surrogate model assisted differential evolution for antenna synthesis (SADEA), is presented in this paper. The key ideas are: (1) A Gaussian Process (GP) surrogate model is constructed on-line to predict the performances of the candidate designs, saving a lot of computationally expensive EM simulations. (2) A novel surrogate model-aware evolutionary search mechanism is proposed, directing effective global search even when a traditional high-quality surrogate model is not available. Three complex antennas and two mathematical benchmark problems are selected as examples. Compared with the widely used differential evolution and particle swarm optimization, SADEA can obtain comparable results, but achieves a 3 to 7 times speed enhancement for antenna design optimization.
PbTe/Pb/sub 1-x/Sn/sub x/Te (x<or=0.18) multiquantum wells: magnetooptics, four-wave mixing, and band structure (1988)

Theoretical and experimental investigations on a narrow-gap multiquantum well (MQW) system with a many-valley band structure: PbTe/PbSnTe are presented. This system has a number of interesting features, including weak confinement of electrons and strain splitting of equivalent L-states, comparable to the conduction-band discontinuities. The result of empirical tight-binding calculations, namely, a type I band alignment, is confirmed by magnetooptical investigations in both magnetic-field orientations parallel and perpendicular to the layers. An envelope function calculation including quantizing magnetic fields is used for the analysis.<<ETX>>
