Optimization of the MacAdam-Modified 1965 Friele Color-Difference Formula (1967)

The adjustable parameters in a MacAdam-modified version of Friele’s 1965 proposal for calculating color differences have been optimized, according to a criterion of MacAdam, to fit PGN experimental data. The mean-square error of fitting is 0.030. The distribution of the resulting color-metric coefficients more closely approximates those of the PGN data than do previous versions of Friele’s proposals. The optimized primaries have chromaticity coordinates of x = 0.74054, y = 0.25946 for the red; x = −1.11696, y = 2.11696 for the green; and x = 0.13939, y = −0.03454 for the blue primary.

A Study on the Development of Collaborative Model for Archiving an Electronic Book (2010)

The purpose of this study is to develop a collaborative model for the archiving and preservation of an electronic book(e-book). In this study the way of the archiving and preservation for the e-book to deal with the technology evolution was suggested. Accordingly, the survey was made for obtaining the present status of the production and distribution of the domestic Online e-book. It is the same as the operation status of the archiving and preservation for the Online e-book worldwide. A collaborative model for accessible to preserved data, regardless of time period, was proposed for archiving the e-book, based on the OAIS reference model. There are three different models, suggested for domestic; the safe place model by law, the individual preservation/Peer-to-Peer model, and the preservation center model for e-book archiving. Among them, the safe place model by law was proposed for the optimum model of archiving an e-book at present.
Photovoltaic properties and barrier heights of single-crystal and polycrystalline Cu2O–Cu contacts (1973)

The spectral distribution of the photovoltaic response of polycrystalline and single-crystal Cu2O–Cu contacts was measured at room temperature using a chopped light technique. The single-crystal contacts were formed by reducing the (111) surface of single-crystal Cu2O to copper using atomic hydrogen at room temperature. Prior to the reduction, a departure from stoichiometry was induced in the single crystals by treatment at 750 or 960°C in a known and controllable partial pressure of oxygen. The polycrystalline contacts were prepared from polycrystalline copper plate partially oxidized to Cu2O at 1000°C. The photoresponse measurements indicate that the dominant photovoltaic mechanisms in Cu2O–Cu contacts are hole photoemission from Cu into Cu2O when hv &lt; Eg and electron injection from Cu2O into Cu when hv &gt; Eg. Barrier heights determined from the threshold of the hole photoemission process measured 0.75±0.06 eV for the single-crystal contacts and 0.75±0.02 eV for the polycrystalline contacts. It is shown that the observed variation in the barrier height of the single-crystal contacts may be due to barrier lowering by the Schottky effect.
Applying Neural Networks to the Solution of the Inverse Heat Conduction Problem in a Gun Barrel (2008)

The primary cause of gun barrel erosion is the heat generated by the shell as its travels along the barrel. Therefore, calculating the heat flux input to the gun bore is very important when investigating wear problems in the gun barrel and examining its thermomechanical properties. This paper employs the continuous-time analog Hopfield neural network (CHNN) to compute the temperature distribution in various forward heat conduction problems. An efficient technique is then proposed for the solution of inverse heat conduction problems using a three-layered backpropagation neural network (BPN). The weak generalization capacity of BPN networks when applied to the solution of nonlinear function approximations is improved by employing the Bayesian regularization algorithm. The CHNN scheme is used to calculate the temperature in a 155mm gun barrel and the trained BPN is then used to estimate the heat flux of the inner surface of the barrel. The results show that the proposed neural network analysis method successfully solves forward heat conduction problems and is capable of predicting the unknown parameters in inverse problems with an acceptable error.
컴퓨터 본위 수업에 있어서 자기규제 기능의 수준별 학습자 통제와 프로그램 통제의 수업방략 비교 (1994)

The major purpose of this study was to investigate the effect s of learner control and program control by the level of self- regulatory skills on learng from computer - based instruct ion. Subject s participated in this study were 48 6th grader s attending Andong Elementary School affiliated at Taegu Teacher s `` College. They were measured with self - regulatory skills questionnaire adapted from Zimmerman and Martinez``s self - regulated learning interview, and Pintrich and Degroot``s self- regulated learning measures, and divided into high or low skills group, according to the level of their skills. And then the member of each group was randomly assigned to learner - or program- controlled instructional strategy. Instructional materials used in this study was computer - based program developed by Carrier et al. to teach the concept s of advertisement propaganda technique. It was adapted for the purpose of the study. Tyetype of instructional control was learner control and program control. Student s under learner control were given instructional control over opt ions of contents, sequences, review and pace. Student s under program control were taught the same instructional contents, sequences, and review according to predetermined program except for pace. They learned the concept son Macintosh computer over three consecutive days four student s at a time, two from learner control group and the other from program control group. Right after studying, the posttest comosed 15 items with 5 options were admnistrered. Also, learning time required to be done the instruction was individually measured. The experimental design of this study was randomized block 2 ×2 design. ANOVA methods were used to analyze the collected data. The first result from this study appeared that although the level of students`` self - regulatory skills had effect s on their academic achievement, it was not as effective as the results of previous studies. The second finding showed that student s with low self - regulatory skills learned better under program control than did under learner contol. It suggested that students`` appropriate self- regulatory skills should be obtained to effectively use learner - controlled strategy in computer - based instruction. Finally, the third outcome was that there was no significant relationships in learning time required to finish the task between the level of self- regulatory skills and the type of instructional control, but while students with high self- regulatory skills took more learning time under learner control, students with low skills did more learning time under program control, respectively. In conclusion, learners`` self- regulatory skills such a s strategic knowledge or study skills seem to be a compelling variable for learner control to be effectively exercised in computer - based instruction. Implications of the findings suggest that when designing computer - based instruction for the use of learner control strategy, the level of students`` self - regulatory skills could be considered.
Psychoneuroendocrine stress responses and mood as related to the menstrual cycle. (1985)

Psychoneuroendocrine stress responses were studied in normally ovulating women in the follicular, ovulatory, and luteal phases of two consecutive menstrual cycles. Psychologic stress was induced by having the subjects perform a battery of cognitive tasks under time pressure. Blood samples were drawn after each session for radioimmunoassay of 17 beta-estradiol, progesterone, luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone, prolactin, cortisol, and androstenedione. Urine samples were obtained for estimation of adrenaline, noradrenaline, and cortisol. The results showed that psychoneuroendocrine stress responses as estimated by urinary excretion of adrenaline and noradrenaline varied significantly across the menstrual cycle, the highest values being obtained in the luteal phase. Self-reported mood and somatic symptoms showed distinct phase-related changes, with more negative mood states predominating in the luteal and menstrual phases and increased positive mood states in the follicular and ovulatory phases.
Study of the obstacle avoidance plan of UAV based on IRIS algorithm (2017)

Although unmanned aerial vehicle (UAV) shows great advantages and some new potential applications in recent years as an effective tool for investigation, fighting and defense, yet, how to give full play to its role still remains the focus of attention. To improve the fighting efficiency of UAV and expand the range of its applications, the obstacle avoidance problem of UAV during autonomous cruise should be solved at first. This paper mainly studies the obstacle avoidance algorithm for UAV, and proposes an obstacle avoidance plan based on IRIS (Iterative Regional Inflation by Semidefinite) and APF (Artifical Potential Field), i.e. IRIS-APF obstacle avoidance plan. According to the requirements and constraints on UAV autonomous cruise, the IRIS and APF are optimized and combined effectively, to realize the IRIS algorithm in 2d and 3d environments, control the UAV avoidance of static obstacles in 2d environment, and ensure the general heading direction of UAV towards the target. Through simulation verification, the IRIS-APF obstacle avoidance plan proposed herein not only achieves the goal of obstacle avoidance, but also realizes high algorithm speed and accuracy under the high real-time request during UAV advancement process.

Low-dose UVB irradiation stimulates matrix metalloproteinase-1 expression<i>via</i>a BLT2-linked pathway in HaCaT cells (2010)

Skin exposure to low-dose ultraviolet B (UVB) light up-regulates the expression of matrix metalloproteinase-1 (MMP-1), thus contributing to premature skin aging (photo-aging). Although cyclooxygenase-2 (COX- 2) and its product, prostaglandin E(2) (PGE((2))), have been associated with UVB-induced signaling to MMP expression, very little are known about the roles of lipoxygenases and their products, especially leukotriene B((4)) (LTB((4))) and 12(S)-hydroxyeicosatetraenoic acid (12(S)-HETE), in MMP-1 expression in skin keratinocytes. In the present study, we demonstrate that BLT2, a cell surface receptor for LTB((4)) and 12(S)-HETE, plays a critical role in UVB-mediated MMP-1 upregulation in human HaCaT keratinocytes. Moreover, our results demonstrated that BLT2-mediated MMP-1 upregulation occurs through a signaling pathway dependent on reactive oxygen species (ROS) production and the subsequent stimulation of ERK. Blockage of BLT2 via siRNA knockdown or with the BLT2-antagonist LY255283 completely abolished the up-regulated expression of MMP-1 induced by low-dose UVB irradiation. Finally, when HaCaT cells were transiently transfected with a BLT2 expression plasmid, MMP-1 expression was significantly enhanced, along with ERK phosphorylation, suggesting that BLT2 overexpression alone is sufficient for MMP-1 up-regulation. Together, our results suggest that the BLT2-ROS- ERK-linked cascade is a novel signaling mechanism for MMP-1 upregulation in low-dose UVB- irradiated keratinocytes and thus potentially contributes to photo-aging.

PCR amplification of crude blood on microscope slides in the diagnosis of Trypanosoma evansi infection in dairy cattle. (1995)

In this study, we compared four T. evansi detection tests (Direct examination, Card Agglutination mouse inoculation and Polymerase Chain Reaction (PCR) in a natural infection of dairy cattle in central Thailand. The samples for PCR amplification were collected either in microfuge tubes or on microscope slides and the amplification results were compared. Collecting the samples on slides was faster and more convenient than collection in tubes. Comparable results were obtained from PCR amplification of both tube- and slide collected samples, processed twelve to fourteen days after collection. PCR was the most sensitive of the methods under comparison, using the mouse inoculation test as golden standard. The specificity of the PCR test under study is further discussed in this paper.

MOSSIM: A Switch-Level Simulator for MOS LSI (1981)

The logic simulator MOSSIM is designed specifically to serve the needs of the MOS LSI designer. It models a MOS circuit as a network of field-effect transistor "switches", with node states 0, 1, and X (unknown) and transistor states "open", "closed", and "unknown". MOSSIM has proved quite versatile and accurate in simulating a variety of MOS designs including ones for which the network was extracted automatically from the mask specifications. Because it models the network at a logical level, it has a performance comparable to conventional logic gate simulators.
Adaptive modulation and regenerator-aware dynamic routing algorithm in elastic optical networks (2015)

Elastic optical network (EON) is a promising technology that provides flexible modulation format conversion, which allows more efficient use of spectrum resources comparing to classical fix-grid in WDM networks. In addition, a significant issue observed currently is the predominant role of cloud computing and content-oriented services provided by geographically dispersed data centers. Consequently, an anycast transmission - defined as one-to-one-of-many - gains much attention due to the need for cost-effective and scalable data delivery in inter-data center networks. In this paper, we address the Routing, Modulation and Spectrum Allocation (RMSA) problem in the context of dynamic routing for anycast and unicast traffic in EONs. We propose a new adaptive and regenerator-aware algorithm for dynamic RMSA that facilitates the possibility of modulation change along the lightpath. Numerical experiments clearly show advantage of our approach comparing to previous methods in terms of blocking probability. Moreover, our results show an interesting trade-off between blocking probability and the usage of regenerators.
Aptamer Selection Technology and Recent Advances (2015)

Over the last decade, aptamers have begun to find their way from basic research to diverse commercial applications. The development of diagnostics is even more widespread than clinical applications because aptamers do not have to be extensively modified to enhance their in vivo stability and pharmacokinetics in diagnostic assays. The increasing attention has propelled the technical progress of the in vitro selection technology (SELEX) to enhance the efficiency of developing aptamers for commercially interesting targets. This review highlights recent progress in the technical steps of a SELEX experiment with a focus on high-throughput next-generation sequencing and bioinformatics. Achievements have been made in the optimization of aptamer libraries, separation schemes, amplification of the selected libraries and the identification of aptamer sequences from enriched libraries.
Antitumor activity of pluripotent cell-engineered vaccines and their potential to treat lung cancer in relation to different levels of irradiation (2016)

Cancer stem cells (CSCs) are critical for tumor initiation/maintenance and recurrence or metastasis, so they may serve as a potential therapeutic target. However, CSC-established multitherapy resistance and immune tolerance render tumors resistant to current tumor-targeted strategies. To address this, renewable multiepitope-integrated spheroids based on placenta-derived mesenchymal stem cells (pMSCs) were X-ray-modified, at four different irradiation levels, including 80, 160, 240, and 320 Gy, as pluripotent biologics, to inoculate hosts bearing Lewis lung carcinoma (LL2) and compared with X-ray-modified common LL2 cells as control. We show that the vaccines at the 160/240 Gy irradiation levels could rapidly trigger tumor cells into the apoptosis loop and evidently prolong the tumor-bearing host's survival cycle, in contrast to vaccines irradiated at other levels (P<0.05), with tumor-sustaining stromal cell-derived factor-1/CXCR4 pathway being selectively blockaded. Meanwhile, almost no or minimal toxicity was detected in the vaccinated hosts. Importantly, 160/240 Gy-irradiated vaccines could provoke significantly higher killing of CSCs and non-CSCs, which may provide an access to developing a novel biotherapy against lung carcinoma.
Hybrid position and force control of a robot arm equipped with joint torque sensors (2013)

A force/torque sensor, which is usually mounted at the wrist of a robot arm, is often used to implement force control. However, this sensor is very expensive and can only measure the forces and moments acting at the end-effector, so it cannot detect collisions occurring at parts other than the end-effector. To deal with these problems, we developed a robot arm in which joint torque sensors are installed at each joint instead of a force/torque sensor. With these torque sensors, hybrid position/force control can be conducted without a force/torque sensor. Experiments were conducted in which a robot arm draws a symbol on a board using a marker attached at the end-effector. These experiments show that position and force control are possible in any direction by using a robot arm with a torque sensor at each joint.
Urban Network Analysis by Random Graphs and the Estimate of the Length of Minimum Spanning Trees (1985)

From this point of view, we shall need to analyse an energy flow or information flom through the graphs. We shall present a typical proble which can be applied to a general case. So that, how long is the minimum spanning tree on the n-points scattered on a square 1×1? Our aim is to present the answer that an expected value of this length is almost surely at least 0.564√n by using random graph theory.

BRAINS: Blog Rendering and Accessing INstantly System (2006)

A blog (shortened from 'weblog') is a trendy way to share personal journal with others in the cyber world. Traditionally rendering and accessing blogs are normally conducted at a stationary PC. However, such a scheme hinders blog users from writing and reading blogs timely. A short-lived idea came out and passed away suddenly. To facilitate the instant blog updating and retrieving, we combined cellular messaging (SMS/MMS messaging and MMS/WAP push) and open sources (Blosxom and Apache) to develop a novel system for the blog rendering and accessing instantly (BRAINS). BRAINS enables blog users to note down their whims and share interests anytime and anywhere. Blog journalists can utilize their mobile phones in hand to compose and deliver blogs to BRAINS by SMS and MMS messaging at their pleasure. Through p re-registering on BRAINS, readers also can get the up-to-date blogs or notification immediately by MMS push or WAP push respectively. With pervasive networks, BRAINS makes mobile blog rendering and accessing more evident.
Amino Acids Activate Mammalian Target of Rapamycin Complex 2 (mTORC2) via PI3K/Akt Signaling (2010)

The activity of mammalian target of rapamycin (mTOR) complexes regulates essential cellular processes, such as growth, proliferation, or survival. Nutrients such as amino acids are important regulators of mTOR complex 1 (mTORC1) activation, thus affecting cell growth, protein synthesis, and autophagy. Here, we show that amino acids may also activate mTOR complex 2 (mTORC2). This activation is mediated by the activity of class I PI3K and of Akt. Amino acids induced a rapid phosphorylation of Akt at Thr-308 and Ser-473. Whereas both phosphorylations were dependent on the presence of mTOR, only Akt phosphorylation at Ser-473 was dependent on the presence of rictor, a specific component of mTORC2. Kinase assays confirmed mTORC2 activation by amino acids. This signaling was functional, as demonstrated by the phosphorylation of Akt substrate FOXO3a. Interestingly, using different starvation conditions, amino acids can selectively activate mTORC1 or mTORC2. These findings identify a new signaling pathway used by amino acids underscoring the crucial importance of these nutrients in cell metabolism and offering new mechanistic insights.
Language modeling for dialog system (2000)

Language modeling for speech recognizer in dialog systems can take two forms. Human input can be constrained through a directed dialog, allowing the decoder to use a state-specific language model to improve recognition accuracy. Mixedinitiative systems allow for human input that while domainspecific might not be state-specific. Nevertheless, for the most part human input to a mixed-initiative system is predictable, particularly when given information about the immediately preceding system prompt. The work reported in this paper addresses the problem of balancing state-specific and general language modeling in a mixed-initiative dialog system. By<br>incorporating dialog state adaptation of the language model, we have reduced the recognition error rate by 11.5%
The Fumed Silica Surface:  A Study by NMR (1996)

High-resolution solid-state NMR techniques were used to investigate the surface structure of Cab-O-Sil fumed silica. 1H NMR results obtained from CRAMPS, MAS-only and relaxation studies reveal the existence of both hydrogen-bonded silanols and isolated silanols on the Cab-O-Sil surface. A systematic dehydration study of fumed silica was carried out, with results on the quantity of each type of silanol on the surface at various dehydration stages. 29Si CP-MAS experiments, including CP spin dynamics studies and various other relaxation studies, were employed to probe hydrogen bonding and the local structural environments of various hydroxyl groups of silica surfaces. 29Si CP-MAS experiments on water-treated and deuterium-exchanged Cab-O-Sil indicate the existence of interparticle silanols and internal silanols in fumed silica. 1H and 29Si NMR show that for fumed silica both isolated and hydrogen-bonded silanols are present on the surface of an untreated sample, in contrast to the case of silica gel, where all silanols of an untreated sample are hydrogen bonded.
