Applications of Laser and Synchrotron Based ARPES to Photocathode Research (2010)

Laser angle resolved photoelectron spectroscopy (ARPES) provides unique information about angle and energy distribution of photoelectrons. Laser ARPES gives unique insight into how NEA materials work. ARPES combined with some ancillary measurements gives a very complete picture of system electronic physics. For H:C[100] there is now a clear program for engineering as well as development analogous systems. ARPES well suited for identifying 'ideal' photocathodes with intrinsically low emittance and high QE.
Study on the Promotion of HLA-matched Platelet Supply in Korea (2010)

Background: Platelet transfusion refractoriness can develop in patients after multiple transfusions of platelets. Once patients develop platelet refractoriness caused by immunological factors, HLA-matched platelet transfusion is required. However, there is no system to supply HLA-matched platelets in Korea. This study was performed to find way to promote the HLA-matched platelet supply in Korea. Methods: The status of platelets supply in Korea and the frequency of platelet refractoriness in four university hospitals during 2005 were analyzed. It was obtained that the number of ordered and positive cases for the anti-platelet antibody, HLA antibody screening, and Panel Reactive Antibody test among inpatients of hematological malignancies. And the means to use the HLA-A, B data of unrelated bone marrow donors was searched. Results: Platelet supply increased annually and totally 1,558,395 units were supplied in 2005, from Korean Red Cross blood centers. The frequency of platelet transfusion refractoriness was 12.4%, among them 10.4% showed anti-platelet or anti-HLA antibodies positive. A revision of the related law was required to use the HLA data of unrelated bone marrow donors. Conclusion: Immunological factors were observed in about 10% of patients with platelet transfusion refractoriness. HLA-matched platelet could be widely available if the HLA-typed donor registry is established in the Korean Red Cross after the revision of the related law.
Silica‐Supported Pentamethylcyclopentadienyl Ytterbium(II) and Samarium(II) Sites: Ultrahigh Molecular Weight Polyethylene without Co‐Catalyst (2018)

Abstract Designing highly active supported ethylene polymerization catalysts that do not require a co‐catalyst to generate electrophilic metal alkyl species is still a challenge despite its industrial relevance. Described herein is the synthesis and characterization of well‐defined silica‐supported cyclopentadienyl Ln II sites (Ln=Yb and Sm) of general formula [(≡SiO)LnCp*]. These well‐defined surface species are highly activite towards ethylene polymerization in the absence of added co‐catalyst. Initiation is proposed to occur by single electron transfer.
Symptomatic Relief Associated With Eyelid Hygiene in Anterior Blepharitis and MGD (2012)

The results showed that eyelid hygiene with Blephaclean wipes by subjects with anterior blepharitis or MGD significantly decreased their associated symptomatology and increased their ocular comfort. The data confirmed the efficiency of the clinical methodology, put forward of 3 weeks of intensive use (twice a day) of eyelid wipes followed by maintenance use (once a day); that approach achieved a rapid symptomatic improvement that was maintained over time.
Coherent vibrational motion in metal particles: Determination of the vibrational amplitude and excitation mechanism (2002)

Ultrafast laser excitation of metal particles coherently excites the symmetric breathing mode. This changes the electron density in the particle, which produces a periodic redshift in the position of the plasmon band. In this paper transient absorption data recorded over a range of wavelengths are analyzed to determine the amplitude of the breathing motion for 24.2 nm radius Au particles. The results are compared to a model calculation where the expansion coordinate is treated as a damped harmonic oscillator and the driving force is thermal expansion due to lattice heating (the temperature rise is determined from the energy absorbed by the sample). The only adjustable parameters in these calculations are the dephasing time of the oscillations and the time scale for energy transfer to the solvent. The experimental and calculated vibrational amplitudes are in excellent agreement, which shows that all the absorbed energy goes into expansion. However, the phases of the calculated and experimental traces do not match. The calculations can be brought into almost perfect agreement with the experimental results by including hot-electron pressure effects in the coefficient for thermal expansion of the particles. This contribution is significant in our experiments because laser excitation initially creates a very high electronic temperature. A simple expression for the time dependence of the transient absorption signal is also derived that explicitly accounts for sample polydispersity. In this expression the beat period is related to the mean radius, and the damping time to the mean radius and the width of the size distribution. Thus, time-resolved laser experiments can be used to obtain accurate information about the size distribution of metal particle samples.
Predominant role of hypoxia-inducible transcription factor (Hif)-1alpha versus Hif-2alpha in regulation of the transcriptional response to hypoxia. (2003)

Tumor hypoxia induces the up-regulation of a gene program associated with angiogenesis, glycolysis, adaptation to pH, and apoptosis via the hypoxia-inducible transcription factors (Hifs) 1 and 2. Disruption of this pathway has been proposed as a cancer therapy. Here, we use short interfering RNAs to compare specific inactivation of Hif-1alpha or Hif-2alpha and show markedly different cell type-specific effects on gene expression and cell migration. Remarkably, among a panel of hypoxia-inducible genes, responses were critically dependent on Hif-1 alpha but not Hif-2 alpha in both endothelial and breast cancer cells but critically dependent on Hif-2 alpha in renal carcinoma cells.
Lead‐Free, Blue Emitting Bismuth Halide Perovskite Quantum Dots (2016)

Abstract Lead halide perovskite quantum dots (QDs) are promising candidates for future lighting applications, due to their high quantum yield, narrow full width at half maximum (FWHM), and wide color gamut. However, the toxicity of lead represents a potential obstacle to their utilization. Although tin(II) has been used to replace lead in films and QDs, the high intrinsic defect density and oxidation vulnerability typically leads to unsatisfactory material properties. Bismuth, with much lower toxicity than lead, is promising to constitute lead‐free perovskite materials because Bi 3+ is isoelectronic to Pb 2+ and more stable than Sn 2+ . Herein we report, for the first time, the synthesis and optical characterization of MA 3 Bi 2 Br 9 perovskite QDs with photoluminescence quantum yield (PLQY) up to 12 %, which is much higher than Sn‐based perovskite nanocrystals. Furthermore, the photoluminescence (PL) peaks of MA 3 Bi 2 X 9 QDs could be easily tuned from 360 to 540 nm through anion exchange.
Optimizing the Performance of Automated Business Processes Executed on Virtualized Infrastructure (2014)

With few exceptions, the opportunities cloud computing offers to business process management (BPM) technologies have been neglected so far. We investigate opportunities and challenges of implementing a BPM-aware cloud architecture for the benefit of process runtime optimization. Processes with predominantly automated tasks such as data transformation processes are key targets for this runtime optimization. In theory, off-the-shelf mechanisms offered by cloud providers, such as horizontal scaling, should already provide as much computational resources as necessary for a process to execute in a timely fashion. However, we show that making process data available to scaling decisions can significantly improve process turnaround time and better cater for the needs of BPM. We present a model and method of cloud-aware business process optimization which provides computational resources based on process knowledge. We describe a performance measurement experiment and evaluate it against the performance of a standard automatic horizontal scaling controller to demonstrate its potential.

Building Web 2.0 (2007)

The global buildup of Internet connectivity and growing availability of inexpensive computing and communication devices have made the World Wide Web a virtual continent that is borderless. Anyone in the world with a computer and Internet access can now explore, join, build, or abandon any Web community at any time. This new freedom is often attributed to the "Web 2.0 era" of services and applications that let webizens easily share opinions and resources. Consequently, users can collectively contribute to a Web presence and generate massive content behind their virtual collaboration.

JOINING STANDARD AND INVENTIVE DESIGN. APPLICATION TO INJECTION MOLDING (2005)

Innovation is a key issue in current global economy, and engineering design process is one of the main components of both radical and incremental innovation. Inventive level of the technical problem design process should solve changes all along the system lifecycle. Solving this technical problem is risky, as robust technical knowledge is not yet present. Nevertheless, innovation has to be introduced. To solve this dilemma, we propose to develop a design process joining standard and inventive approaches. In this paper we show that technical knowledge can be the common resource of these two different approaches. Standard design utilises it to reuse known technical solutions, whereas inventive approach requires analysing and formulating the problem that is to be solved using TRIZ solving tools, creating either an incremental or a radical innovation. We identified that standard and inventive approaches can collaborate to initiate the system evolution and also that standard approach can be used to investigate and collect knowledge later processed by inventive approach.
Simulation of Scavenging in a Small Two-Stroke Gasoline Engine Typical in South Asia (2007)

&lt;div class="htmlview paragraph"&gt;Popular and inexpensive, small carbureted two-stroke engines in developing countries dominate city air pollution, mostly with hydrocarbon and particulate/aerosol emissions that short-circuit the scavenge process. Retrofit of a direct fuel-injection system can provide significant emissions reduction, if optimum injection timing is used to promote mixing while avoiding premature fuel loss. This required detailed understanding of the scavenging flow. Computational study of scavenge flow in a typical small vehicle engine is accomplished using multi-dimensional moving-mesh unsteady and quasi-steady models. Both models indicate that typical multi-port inlet placement and timing allow significant mixture short-circuit, consistent with emissions observations. Residual gas is well scavenged from the hemi-spherical head cylinder. Insights are derived for future incorporation of direct fuel injection for similar engines.&lt;/div&gt;
Prognosis of Bearing Degeneration Using Adaptive Quaternion Least Mean Biquadrate Under Framework of Hypercomplex Data (2019)

Prognostics of bearing degeneration play a crucial role in implementation of systems maintenance strategies. Although numerous classical prognostic models have been developed, these models are carried out based on channel-wise processing and therefore fail to capture the inherent nonlinear and coupling nature of multi-dimensional or multi-channel data. To address this issue, a novel prognostics method based on adaptive quaternion-valued least-mean biquadrate (AQ-LMB) algorithm is proposed for a unified processing of hypercomplex data by the virtue of quaternion algebra. The cost function of the proposed AQ-LMB algorithm is designed via the biquadrate form of system output error to adapt to the more common nonlinear and non-Gaussian data, and the update weight vector is derived through Hamilton calculus instead of traditional complex gradient calculation. First, the time series of health indicators (e.g., root-mean-square, RMS) derived from historical data are decomposed by a nonconvex sparse regularization (SR) algorithm associated with a nonconvex penalty, that is, the low frequency trend component (LFC) and high frequency noise component (HFC) are obtained. Then both LFC and HFC are respectively predicted by the AQ-LMB algorithm. The final predicted health indicators can be obtained by integrating the correspondingly predicted LFC and HFC. The separate analysis of both sub-components makes it possible to distinguish their respective contributions to the entire degeneration process, thus avoiding false deviation and improving the prediction accuracy. Finally, the effectiveness of the proposed nonconvex SR and AQ-LMB approach in improving prognostic accuracy is illustrated via three-and four-dimensional run-to-failure datasets of the rolling bearings.

Characterization of Intermetallic Compounds in Dissimilar Material Resistance Spot Welded Joint of High Strength Steel and Aluminum Alloy (2011)

Dissimilar materials of H220 Zn-coated high strength steel and 6008 aluminum alloy were welded by median frequency resistance spot welding. Interfacial characteristics and kinetics of growth of intermetallic compound layer at steel/aluminum interface in the welded joint were investigated. The intermetallic compound layer was mainly made up of η-Fe2Al5 and θ-FeAl3 phases, and its morphology and thickness varied with positions along the interface. The growth behavior of the intermetallic compound layer was dominated by η-Fe2Al5, which exhibited parabolic characteristic. The growth coefficient of η-Fe2Al5 could be expressed as k = k0 exp(–Q/RT) with k0 of 132 m2/s and Q of 239 kJ/mol. The kinetics of growth of the intermetallic compound layer indicated that its formation and growth were mainly driven by reactive diffusion between Fe and Al atoms, and hence the thickness and morphology of the layer were dependant on interaction time between liquid aluminum alloy and solid steel, and also interfacial temperature history during welding. The brittle intermetallic compound layer at the steel/aluminum interface was the weak zone where cracks inclined to derive and propagate during tensile shear testing. The fracture surfaces of the welded joint displayed mixed fracture morphology with both brittle and ductile features.
Caveolae and Caveolins in the Cardiovascular System (2004)

Caveolae and the caveolae coat proteins, caveolins, are putatively implicated in many cellular processes, including transcytosis of macromolecules, cholesterol transport, and signal transduction. Recent insights into the physiological and pathophysiological roles of these organelles and the caveolins from genetically modified mice suggest that they may be profoundly important for postnatal cardiovascular function, including endothelial barrier function, regulation of nitric oxide synthesis, cholesterol metabolism, and cardiac function.

Trifluoropropyltrimethoxysilane as an Electrolyte Additive to Enhance the Cycling Performances of Lithium-Ion Cells (2014)

본 연구에서는 불소계 실란을 첨가제로 사용하여 전해액의 열화 반응을 억제함으로써 리튬이온전지의 싸이클 특성을 향상시키고자 하였다. 첨가제로 사용된 trifluoropropyltrimethoxysilane은 리튬염과 카보네이트계 유기 용매로 이루어진 액체 전해질보다 전기화학적 산화, 환원 분해반응이 먼저 일어나 음극 및 양극 표면에서 안정적인 고체전해질계면 (solid electrolyte interphase, SEI) 막을 형성하며, 5 wt.%의 첨가제를 포함하는 경우 가장 우수한 전기화학적 특성을 나타내었다. SEM 및 XPS 분석을 통해 전극 표면에 생성된 피막의 화학 성분을 분석하였으며, 이들 결과로부터 새로운 SEI 형성 첨가제로서 불소계 실란의 가능성을 확인하였다. In this study, we tried to improve the cycling performance of lithium-ion batteries by suppressing decomposition of the electrolyte solution containing fluorsilane-based additive. Trifluoropropyltrimethoxysilane was electrochemically oxidized and reduced prior to the decomposition of the liquid electrolyte composed of lithium salt and carbonate-based organic solvent. Thus, the stable solid electrolyte interphase (SEI) layer on both negative electrode and positive electrode was formed, and it was confirmed that the cycling performance of lithium-ion batteries assembled with electrolyte solution containing 5 wt.% trifluoropropyltrimethoxysilane was the mostly enhanced. The products formed on electrodes were analyzed by the SEM and XPS analysis, and it was demonstrated that trifluoropropyltrimethoxysilane can be one of the promising SEI-forming additives.
The Effects of Semantic Priming and Word Repetition on Event‐Related Potentials (1985)

ABSTRACT Event‐related potentials (ERPs) were recorded during the performance of a lexical decision task, in which a proportion of the words were either semantic associates or repetitions of the preceding word. Reaction times were faster to both the second member of associated pairs (targets) and repeated words, with the latter facilitatory effect being more than twice that of the former. ERPs to the semantic primes were more negative‐going than those to targets. This difference peaked around 400–450 ms after stimulus onset. Comparison of unrepeated and repeated words revealed a larger and temporally more extended difference, with a similar scalp topography. The prime‐target differences are interpreted as a further example of the sensitivity of the ‘N400’ component of the ERP to semantic relationships between words. The differences between the repetition and priming effects in ERPs are considered equivocal with respect to the view that the associated behavioural effects are caused by different cognitive mechanisms.
The Effect of Gases Emitted From Batch/Glass Reactions on the Combustion Space Flow Field (2003)

The concept of ‘coupling’ a combustion space CFD code to a code that models the molten glass flow is not a new idea. However, this concept has been limited to an energy coupling; the heat flux calculated in the combustion space model is used to drive the glass melt while the calculated surface temperature is used in the radiative heat transport calculation in the combustion space computation. In reality, there is significant mass (mostly gas) transport from the batch/molten glass into the combustion space. This is an important phenomenon to be modeled since these gases, particulates and volatiles will be removed from the combustion chamber and hence raise environmental considerations. In addition, these released gases have a distinct influence on the flow field in the combustion space. The ANL Glass Furnace Model has been augmented to calculate the chemical reactions that release gases in the batch and in the melt. This work presents preliminary results indicating the effect of these gases on the combustion space.

Comparison of Adaptive Behavior Measures for Children with HFASDs (2013)

Adaptive behavior rating scales are frequently used to gather information on the adaptive functioning of children with high-functioning autism spectrum disorders (HFASDs), yet little is known about the extent to which these measures yield comparable results. This study was conducted to (a) document the parent-rated VABS-II, BASC-2, and ABAS-II adaptive behavior profiles of 6- to 11-year-olds with HFASDs (including relative strengths and weaknesses); (b) examine the extent to which these measures yielded similar scores on comparable scales; and (c) assess potential discrepancies between cognitive ability and adaptive behavior across the measures. All three adaptive measures revealed significant deficits overall for the sample, with the VABS-II and ABAS-II indicating relative weaknesses in social skills and strengths in academic-related skills. Cross-measure comparisons indicated significant differences in the absolute magnitude of scores. In general, the VABS-II yielded significantly higher scores than the BASC-2 and ABAS-II. However, the VABS-II and ABAS-II yielded scores that did not significantly differ for adaptive social skills which is a critical area to assess for children with HFASDs. Results also indicated significant discrepancies between the children's average IQ score and their scores on the adaptive domains and composites of the three adaptive measures.
A dual operating mode antenna on flexible ground structures for wearable communications (2017)

This paper introduces a dual-band dual-mode button antenna for body centric communications. Integrated on the clothes, the proposed antenna has a miniaturized flexible ground. By employing PIFA and its higher order mode, an omnidirectional pattern and a broad-side directional pattern for on-body and off-body communications are realized at lower and upper bands, respectively. With a flexible ground, this design obtains a robust reflection coefficient against the bending effect of the clothes on human body. When bending on a cylindrical phantom, the button antenna still exhibits the dual-mode characteristic. Owning to the good performance such as miniaturized dimension, dual-mode pattern and flexible ground, the proposed design is a practical candidate for Wireless Body Area Network (WBAN) applications.
