Conjugated Polymers of Fused Bithiophenes with Enhanced π-Electron Delocalization for Photovoltaic Applications (2008)

We designed and synthesized a family of three structurally related conjugated alternating copolymers, namely poly[2,6-(4,4-dioctyl-4H-cyclopenta[2,1-b:3,4-b]dithiophene)-alt-2,7-(4,5-dioctylbenzo[2,1-b:3,4-b′]dithiophene)] (PBDT), poly[2,6-(4,4-dioctyl-4H-cyclopenta[2,1-b:3,4-b′]dithiophene)-alt-2,9-(5,6-dioctylnaphtho[2,1-b:3,4-b′]dithiophene)] (PNDT), and poly[2,6-(4,4-dioctyl-4H-cyclopenta[2,1-b:3,4-b′]dithiophene)-alt-6,9-(2,3-bis((S)-2,6-dimethylheptyl)dithieno[3,2-f:2′,3′-h]quinoxaline] (PQDT). The repeating units of these three copolymers consist of two modified bithiophene units with one of them planarized by bridging benzo, naphtho, and quinoxalino segments, respectively. The 2,6-(4,4-dioctyl-4H-cyclopenta)[2,1-b;3,4-b′]dithiophene moieties were introduced as the other bithiophene unit to improve the solubility of resultant copolymers, facilitating the polymers characterization and photovoltaic devices fabrications. All polymers were fully characterized, and their applications as donor materials in conjunction with PCBM as acceptor in bulk heterojunction (BHJ) photovoltaic devices were tested. The increased conjugation from naphtha and quinoxalino segments over benzo unit led to the decreased band gap of PNDT and PQDT compared to that of PBDT. A lower HOMO level was observed from PQDT due to the presence of two nitrogen atoms in the planarized π system, which rendered the conjugated molecule electron-deficient. BHJ photovoltaic devices made from PQDT:PCBM film (1:1.6, 100 nm) exhibited a Voc value of 0.53 V, a Jsc value of 4.56 mA/cm2, and a FF of 0.47, offering an overall power conversion efficiency of 1.14% and a peak quantum efficiency of 37% from IPCE measurement. The best performance of PQDT among three polymer investigated was correlated with its lower optical band gap (1.96 eV), lower HOMO level (−5.15 eV), and higher hole mobility (5.15 × 10−5 cm2 V−1 s−1). We concluded that the intrinsic electronic properties of these planarized bithiophene moieties offered moderate flexibility in fine-tuning electronic properties of the corresponding copolymers.
Molecular Beam Scattering from Liquid Surfaces (1991)

By means of controlled collisions of atoms and molecules with liquid surfaces, molecular beam experiments can be used to probe how gases stick to, rebound from, and exchange energy with molecules in the liquid phase. This report describes measurements of energy exchange in collisions between gases (neon, xenon, and sulfur hexafluoride) and polyatomic liquids (squalane and perfluoropolyether). Energy transfer depends critically on liquid composition and is more efficient for the hydrocarbon than for the perfluorinated ether.
A Novel Clinical Entity: Triglyceride Deposit Cardiomyovasculopathy Implications and Perspectives from ''Obesity of the Heart'' (2009)

Heart diseases, including atherosclerotic cardiovascular disease and congestive heart failure, are major life-threatening disorders in most countries. Cholesterol is a vital causal factor and focus of research into heart diseases, but the involvement of triglycerides remains unclear. We recently reported a unique patient suffering from severe congestive heart failure and needing cardiac transplantation. Massive accumulation of triglycerides was observed in coronary atherosclerotic lesions as well as in the myocardium, while plasma triglyceride levels were normal. We suggested that this phenotype was a novel clinical entity and named it "Triglyceride deposit cardiomyovasculopathy", or simply "Obesity of the heart". The patient was identified as homozygous for a genetic mutation in the adipose triglyceride lipase, an essential molecule for hydrolysis of intracellular triglycerides. The present paper deals with what we can learn from this single case and discusses its implications for research and clinical medicine related to heart diseases.
Feasibility of Eye-tracking based Glasses-free 3D Autostereoscopic Display Systems for Medical 3D Images (2016)

Medical image diagnosis processes with stereoscopic depth by 3D display have not been developed widely

yet and remain understudied Many stereoscopic displays require glasses that are inappropriate for use in

clinical diagnosis/explanation/operating processes in hospitals. An eye-tracking based glasses-free three-dimensional

autostereoscopic display monitor system has been developed, and its feasibility for medical 3D

images was investigated, as a cardiac CT 3D navigator. Our autostereoscopic system uses slit-barrier with

BLU, and it is combined with our vision-based eye tracking system to display 3D images. Dynamic light field

rendering technique is applied with the 3D coordinates calculated by the eye-tracker, in order to provide a

single viewer the best 3D images with less x-talk. To investigate the feasibility of our autostereoscopic system,

3D volume was rendered from 3D coronary CTA images (512 by 512 by 400). One expert reader identified

the three main artery structures (LAD, LCX and RCA) in shorter time than existing 2D display. The reader

did not report any eye fatigue or discomfort. In conclusion, we proposed a 3D cardiac CT navigator system

with a new glasses-free 3D autostereoscopy, which may improve diagnosis accuracy and fasten diagnosis

process.
LMI-based 2D-3D registration: From uncalibrated images to Euclidean scene (2015)

This paper investigates the problem of registering a scanned scene, represented by 3D Euclidean point coordinates, and two or more uncalibrated cameras. An unknown subset of the scanned points have their image projections detected and matched across images. The proposed approach assumes the cameras only known in some arbitrary projective frame and no calibration or autocalibration is required. The devised solution is based on a Linear Matrix Inequality (LMI) framework that allows simultaneously estimating the projective transformation relating the cameras to the scene and establishing 2D-3D correspondences without triangulating image points. The proposed LMI framework allows both deriving triangulation-free LMI cheirality conditions and establishing putative correspondences between 3D volumes (boxes) and 2D pixel coordinates. Two registration algorithms, one exploiting the scene's structure and the other concerned with robustness, are presented. Both algorithms employ the Branch-and-Prune paradigm and guarantee convergence to a global solution under mild initial bound conditions. The results of our experiments are presented and compared against other approaches.
Effect of Hydrogen Peroxide on Whey Protein Nitrogen Value of Heated Skimmilk (1967)

The effect on the whey protein nitrogen value of skimmilk treated with different concentrations of hydrogen peroxide in the skimmilk 10 rain before it was heated at 85 C for 30 rain was determined. Hydrogen peroxide decreased denaturation of skimnfilk.
Recursive algorithm for state space spectrum estimation (1990)

A new method is proposed for implementing an adaptive state space filter. This method is based upon the matrix minimum principle of optimal control theory. The adaptive state space filter is a two part algorithm. The first part is a recursive algorithm for optimizing a predictor matrix which describes the transformation from past data to future data. A matrix steepest descent algorithm is developed for use as the update equation in optimizing the predictor matrix. The second part determines the system parameters from the optimized predictor matrix by the decomposition of the predictor matrix and the use of projection techniques. The result is the estimation of the innovations realization which can further describe the spectral characteristics of the model.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Production of the Alkaloids Emetine and Cephaeline in Callus Cultures of<i>Cephaelis ipecacuanha</i> (1988)

Callus cultures were established from hypocotyl explants of Cephaelis ipecacuanha, emetine and cephaeline were identified by HPLC in callus cultures. The effect of macrosalts of different basal medium and hormones on growth and alkaloid accumulation in callus tissues was investigated. Best growth in terms of wet/dry weight was obtained on media containing macrosalts of B5 supplemented with 3% sucrose, 8 mg l-1 IBA, 4 mg l-1 IAA, and 4 mg l-1 NAA. The highest yields of alkaloids were detected in medium containing macrosalts of SH with same hormone combination.
what the journals say (2006)

We are continually encouraged to offer a holistic approach to patient care, and in light of recent press attention this study was of particular interest. Complementary therapies have gained popularity over recent years with the general public as well as healthcare professionals. This has been heightened not only by media attention but also as access to services via the internet have become easier. Quite often patients with bowel dysfunction seek alternative methods as they near the end of their medical management and the prospect of surgery loom ever nearer.
Synthesis, structure and luminescent properties of lanthanide fluoroalkoxides (2016)

Alkoxides [Ln(OR)3(DME)]2 (R = CH(CF3)2, Ln = Sm (1), Yb (2)), [Ce(OR)3(Phen)]2 (3) (Phen = 1,10-phenanthroline), [Ce(OR′)3(DME)2]2 (R′ = C(CF3)3) (4), {Gd(OR′)3(DME)2} (5), {Ln2[O(CF3)2C–C(CF3)2O]3} (Ln = Ce (6), Gd (7)), {Ce2[O(CF3)2C–C(CF3)2O]3(Phen)2} (8), and {Ce[O(CF3)2C–C(CF3)2O][O(CF3)2–C(CF3)2OH](Phen)2} (9) were synthesized by the reactions of silylamides Ln[N(SiMe3)2]3 with respective fluorinated alcohols. The heterovalent trinuclear complex {Sm2(μ2-OR)3(μ3-OR)2Sm(OR)2(THF)2.5(Et2O)0.5} (10) was obtained by treatment of SmI2(THF)2 with ROK. The reaction of europium(II) and yttrium(III) silylamides with ROH afforded the heterobimetallic alkoxide {Eu2(μ2-OR)3(μ3-OR)2Y(OR)2(DME)2} (11) containing divalent europium. The molecular structures of 1, 2, 3, 9, 10 and 11 were determined by X-ray analysis. All the prepared cerium derivatives as well as the europium–yttrium isopropoxide upon UV excitation exhibited photoluminescence in the regions of 370–425 (for Ce3+) and 485 nm (for Eu2+) which was assigned to 4d→5f transitions.
Diagonal Rescaling For Neural Networks (2017)

We define a second-order neural network stochastic gradient training algorithm whose block-diagonal structure effectively amounts to normalizing the unit activations. Investigating why this algorithm lacks in robustness then reveals two interesting insights. The first insight suggests a new way to scale the stepsizes, clarifying popular algorithms such as RMSProp as well as old neural network tricks such as fanin stepsize scaling. The second insight stresses the practical importance of dealing with fast changes of the curvature of the cost.
Integrated amorphous silicon photoconductive type image sensor (2003)

The authors report a study on an integrated amorphous silicon photoconductive-type image sensor. The photoconductive-type sensor has the advantage of a high photocurrent. All the elements in an integrated sensor circuit, including sensor, storage capacitor, switch transistor, and matrix wiring, can be fabricated within one deposition process. A novel sandwich structure with a low level-phosphorous-doped layer is proposed to enhance the photoconductivity. A high photoconductivity of 5*10/sup -5/ S cm/sup -1/ has been achieved, with a photosensitivity of 5*10/sup 4/. The key to the sensor is the SiN/a-Si:H interface, which can be controlled by a metal gate underneath the SiN layer. The thin-film transistor with low-level doping in the channel material has an on current of 1 mu A and an on/of ratio of 10/sup 4/.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Lack of CD47 on nonhematopoietic cells induces split macrophage tolerance to CD47<sup>null</sup>cells (2007)

Macrophages recognize CD47 as a marker of "self" and phagocytose CD47(null) hematopoietic cells. Using CD47 chimera models, here, we show that the phagocytic activity of macrophages against CD47(null) hematopoietic cells is conferred by CD47 expression on nonhematopoietic cells, and this "education" process is hematopoietic cell-independent. Macrophages in the chimeras where nonhematopoietic cells express CD47 phagocytose CD47(null) cells, whereas those in the chimeras lacking CD47 on nonhematopoietic cells are tolerant to CD47(null) cells. However, macrophages in the latter chimeras retain phagocytic activity against CD47(null) RBCs, demonstrating a split macrophage tolerance to CD47(null) hematopoietic cells. The findings highlight the potential importance of nonhematopoietic cells in the regulation of macrophage function, and suggest a previously uncharacterized mechanism of macrophage tolerance.
Variational Graph Auto-Encoders (2016)

We introduce the variational graph auto-encoder (VGAE), a framework for unsupervised learning on graph-structured data based on the variational auto-encoder (VAE). This model makes use of latent variables and is capable of learning interpretable latent representations for undirected graphs. We demonstrate this model using a graph convolutional network (GCN) encoder and a simple inner product decoder. Our model achieves competitive results on a link prediction task in citation networks. In contrast to most existing models for unsupervised learning on graph-structured data and link prediction, our model can naturally incorporate node features, which significantly improves predictive performance on a number of benchmark datasets.
An ATP-stabilized inhibitor of the proteasome is a component of the 1500-kDa ubiquitin conjugate-degrading complex. (1992)

Proteins conjugated to ubiquitin are degraded by a 26S (1500-kDa) proteolytic complex that, in reticulocyte extracts, can be formed by the association of three factors: CF-1, CF-2, and CF-3. One of these factors, CF-3, has been shown to be the proteasome, a 650-kDa multicatalytic protease complex. We have purified a 250-kDa inhibitor of the proteasome and shown that it corresponds to CF-2. In the presence or absence of ATP, this factor inhibited hydrolysis by the proteasome of both fluorogenic tetrapeptides and protein substrates. When the inhibitor, proteasome, and CF-1 were incubated together in the presence of ATP and Mg2+, degradation of ubiquitin-125I-lysozyme occurred. Both the inhibitory activity and the ability to reconstitute ubiquitin-125I-lysozyme degradation were very labile at 42 degrees C, but both activities were stabilized by ATP or a nonhydrolyzable ATP analog. SDS/PAGE indicated that the 250-kDa inhibitor fraction contained a major subunit of 40 kDa (plus some minor bands). The 125I-labeled inhibitor and purified proteasome formed a complex. When CF-1, ATP, and Mg2+ were also present, the 125I-labeled inhibitor along with the proteasome formed a complex of 1500 kDa. The inhibitor (CF-2) thus appears to be an ATP-binding component that regulates proteolysis within the 1500-kDa complex.
Phosphate Nutrition of <i>Rhizobium</i> spp (1984)

This study was conducted to determine the behavior of 40 strains from six species of Rhizobium in liquid defined media containing orthophosphate at levels likely to be encountered naturally, ranging from the high concentrations expected in nodules and artificial media to the low concentrations of soil solutions. Storage capacity in strains with high levels (2 mM) of P and ability to utilize this stored P for growth after transfer to low levels (0.06 muM) of P varied with each strain. Storage varied from about 1 to 2% P (dry weight) for all strains, with the number of generations supported dependent on the quantity of P stored and on the utilization efficiency. The ability to store P at high levels is probably less important than the uptake and utilization efficiency of P supplied at low levels. Strains varied greatly in tolerance to low levels of P maintained in solution by an iron oxide buffering system. Differences in growth rate at low levels of P were large enough to be agronomically important.

Implementation of a wireless communication technologies based home security system (2011)

Recently, the demand for home security in Japan is intensifying due to the aging population with low birth rate and the significant increase in number of nuclear family with dual working parents. Some enterprises like SECOM, ALSOK, CSP, provide home security services in Japan. However, most of these services rely on security guards, which is expensive. Besides, some families do not like their homes being under surveillance and monitoring data being kept by a third party. This paper describes a light weighted home security system that exploits the common use of wireless communication technology like mobile phone, Bluetooth communication, wireless sensors, etc. One of the significant advantages is that the monitoring data is kept in a home web server and is shared by family members only. Moreover, the system scale is small and the cost is low, which is more suitable for the smaller scope of a home and a general civilian family.
A Distributed Demand Response Algorithm and Its Application to PHEV Charging in Smart Grids (2012)

This paper proposes a distributed framework for demand response and user adaptation in smart grid networks. In particular, we borrow the concept of congestion pricing in Internet traffic control and show that pricing information is very useful to regulate user demand and hence balance network load. User preference is modeled as a willingness to pay parameter which can be seen as an indicator of differential quality of service. Both analysis and simulation results are presented to demonstrate the dynamics and convergence behavior of the algorithm. Based on this algorithm, we then propose a novel charging method for plug-in hybrid electric vehicles (PHEVs) in a smart grid, where users or PHEVs can adapt their charging rates according to their preferences. Simulation results are presented to demonstrate the dynamic behavior of the charging algorithm and impact of different parameters on system performance.
<title>Automatic retinal image quality assessment and enhancement</title> (1999)

This paper describes a method for machine (computer) assessment of the quality of a retinal image. The method provides an over-all quantitative and objective measure using a quality index Q. The Q of a retinal image is calculated by the convolution of a template intensity histogram obtained from a set of typically good retinal images and the intensity histogram of the retinal image. After normalization, the Q has a maximum value of 1, indicating excellent quality, and a minimum value of 0, indicating bad quality. The paper also presents several application examples of Q in image enhancement. It is shown that the use of Q can help computer scientists evaluate the suitability and effectiveness of image enhancement methods, both quantitatively and objectively. It can further help computer scientists improve retinal image quality on a more scientific basis. Additionally, this machine image quality measure can also help physicians make medical diagnosis with more certainty and higher accuracy. Finally, it should be noted that although retinal images are used in this study, the methodology is applicable to the image quality assessment and enhancement of other types of medical images.
GIS Applications for Optimum Site Selection of Public Facility (2001)

The main purpose of this study is to introduce a new method of evaluation, and to suggest how to apply geographic information system for optimum public facility site selection. For this purpose, a new evaluation model for the site selection is developed. The model provides a simple and easy method of evaluation. It also allows differences among location factors through two step weighting procedures. For a better understanding of the model, solution procedures and visual figures are illustrated with the case of Dalseong-Gun's city hall location example.
Nanostructured porous hollow ellipsoidal capsules of hydroxyapatite and calcium silicate: preparation and application in drug delivery (2008)

We have successfully prepared for the first time hydroxyapatite (HAp) and calcium silicate (CaSiO3) nanostructured porous hollow ellipsoidal capsules which are constructed by nanoplate networks using the inorganic CaCO3 template. CaCO3 ellipsoids are synthesized via the reaction between Ca(CH3COO)2 and NaHCO3 in water and ethylene glycol mixed solvent at room temperature and they are used as the Ca2+ source and cores. Then a PO43− or SiO32− source is added to react with CaCO3 to form a HAp or CaSiO3 shell on the surface of CaCO3 ellipsoids. Dilute acetic acid is used to remove remaining CaCO3 cores. The size and shape of the HAp and CaSiO3 hollow capsules are determined by those of the cores. The thickness of the capsule shell can be controlled by adjusting the concentration of PO43− or SiO32− source. A number of PO43− sources such as dilute H3PO4, Na3PO4 and Na2HPO4 can be used to form HAp hollow capsules with similar morphologies. The drug loading and release behavior of HAp hollow capsules is also investigated. A typical anti-inflammatory drug, ibuprofen, is used for drug loading. The result indicates that HAp hollow capsules have a high specific surface area and high storage capacity, and favorable drug release behavior.
