A Schottky-barrier CCD on GaAs (1977)

Because of it's high electron-mobility GaAs is a promising semiconductor for high speed CCDs. To avoid the problems encountered with MIS-structures (e.g., high surface state density, frequency dependent C(U)-characteristics) a CCD with Schottky-contacts was proposed (Schuermeyer 1972). To our knowledge no operating GaAs-CCD has been reported until now. Basically the structure of our CCD is that of a GaAs MESFET with a sequence of gates. During operation, electrons are injected from the source into the depleted n-type layer. By proper biasing of the Schottky-gates the injected charge is stored or transferred along the interface between active layer and substrate. The signal is detected by use of a monolithically integrated read-out MESFET-amplifier. A three phase-four stage CCD was fabricated on sulphur-implanted active layers on semi-insulating GaAs. The ohmic contacts consist of a layer sequence of GeAuCrAu. CrAu-Schottky-contacts with 6.5 µm in length and 200 µm in width were used. Interelectrode spacing was 1.5 µm. SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> was sputter-deposited for electrode crossover and passivation. Operation of the CCD at 500 kHz showed correct single pulse and step response. The number of stages were too small for accurately measuring the transfer inefficiency, which is estimated to be smaller than 5.10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> . Elements with 8 or 16 stages for determining the transfer inefficiency and the maximum frequency of operation are presently under investigation.
Near-Infrared Photoluminescence of Single-Walled Carbon Nanotubes Prepared by the Laser Vaporization Method (2003)

Single-walled carbon nanotubes (SWNTs) prepared by pulsed laser vaporization, dispersed, and surfactant-stabilized in near-infrared transparent D2O show weak photoluminescence (PL) from ∼1300 up to >1750 nm corresponding to the lowest electronic interband transitions of semiconducting tubes. The characteristic features of this PL, such as a multiple peak emission and a strong excitation wavelength dependence (investigated for λexc from 457 up to 1064 nm), are similar to those reported recently for SWNTs with smaller diameters of around 1 nm (O'Connell et al. Science 2002, 297, 593). The luminescence is significantly polarized with an anisotropy value r of up to 0.32, depending on the excitation and emission wavelengths. The PL data can be used for the structural assignment of emitting tubes; however, in agreement with the results of O'Connell et al., these data are only qualitatively consistent with the tight-binding model widely applied for SWNTs. The luminescence is sensitive to chemical treatment/interactions of SWNTs; much weaker and broader PL was observed above 1300 nm for dispersions of acid-treated tubes in D2O, whereas raw SWNTs in N,N-dimethylformamide show practically no PL. The Raman spectra of dispersed SWNTs differ from those of the solid samples.
Community detection in political Twitter networks using Nonnegative Matrix Factorization methods (2016)

Community detection is a fundamental task in social network analysis. In this paper, first we develop an endorsement filtered user connectivity network by utilizing Heider's structural balance theory and certain Twitter triad patterns. Next, we develop three Nonnegative Matrix Factorization frameworks to investigate the contributions of different types of user connectivity and content information in community detection. We show that user content and endorsement filtered connectivity information are complementary to each other in clustering politically motivated users into pure political communities. Word usage is the strongest indicator of users' political orientation among all content categories. Incorporating user-word matrix and word similarity regularizer provides the missing link in connectivity-only methods which suffer from detection of artificially large number of clusters for Twitter networks.

A study of various tests to detect asymptomatic urinary tract infections in an obstetric population. (1993)

Urine dipstick testing for nitrites identified half of all patients with urinary tract infections and was superior to urinalysis on follow-up visits. Although Gram's staining is more expensive, it was more accurate for AUTI than urinalysis or urine dipstick test for nitrites. Urinalysis was never the test of choice because it was more expensive and detected fewer positive cultures. Leukocyte measurement correlated poorly with AUTI.
Creatinine Inhibits <i>D-</i>Amino Acid Oxidase (2002)

Inhibition of D-amino acid oxidase (DAO) activity by various uremic retention products and guanidino compounds was investigated. Creatinine (CTN) was found to inhibit DAO at a similar concentration in the sera of uremic patients. The inhibition was competitive and the K(i) value was 2.7 mM. Moreover, CTN was shown to interact with flavin adenine dinucleotide (FAD), a coenzyme of DAO. The UV spectral change of FAD bound to DAO was observed in the visible region by addition of CTN. These findings suggest that the increase in serum and tissue CTN concentrations might be responsible, in part, for the increase in D-amino acids in the sera of uremic patients.
Rho Kinase Inhibition by Fasudil in the Striatal 6-Hydroxydopamine Lesion Mouse Model of Parkinson Disease (2014)

Chronic degeneration of nigrostriatal projections, followed by nigral dopaminergic cell death, is a key feature of Parkinson disease (PD). This study examines the neuroprotective potential of the rho kinase inhibitor fasudil in the 6-hydroxydopamine (6-OHDA) mouse model of PD in vivo. C57Bl/6 mice were lesioned by striatal stereotactic injections with 4 μg of 6-OHDA and treated with fasudil 30 or 100 mg/kg body weight via drinking water. Motor behavior was tested biweekly; histologic and biochemical analyses were performed at 4 and 12 weeks after lesion. Motor behavior was severely impaired after 6-OHDA lesion and was not improved by fasudil treatment. Fasudil 100 mg/kg did not significantly increase the number of dopaminergic cells in the substantia nigra after 12 weeks versus lesion controls. Interestingly, however, high-performance liquid chromatography analysis of dopamine metabolites revealed that striatal levels of 3,4-dihydroxyphenylacetic acid were significantly increased after 12 weeks, suggesting a regenerative response. In contrast to recent findings in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridin model, fasudil effects seem limited in this severe 6-OHDA model of PD. Nevertheless, high therapeutic concentrations of fasudil are suggestive of a proregenerative potential for dopaminergic neurons, making further evaluations of rho kinase inhibition as a proregenerative therapeutic strategy in PD promising.
<i>C</i><sub>2</sub>-Symmetric Copper(II) Complexes as Chiral Lewis Acids. Scope and Mechanism of Catalytic Enantioselective Aldol Additions of Enolsilanes to (Benzyloxy)acetaldehyde (1999)

C2-Symmetric bis(oxazolinyl)pyridine (pybox)−Cu(II) complexes have been shown to catalyze enantioselective Mukaiyama aldol reactions between (benzyloxy)acetaldehyde and a variety of silylketene acetals. The aldol products are generated in high yields and in 92−99% enantiomeric excess using as little as 0.5 mol % of chiral catalyst [Cu((S,S)-Ph-pybox)](SbF6)2. With substituted silylketene acetals, syn reaction diastereoselection ranging from 95:5 to 97:3 and enantioselectivities ≥95% are observed. Investigation into the reaction mechanism utilizing doubly labeled silylketene acetals indicates that the silyl-transfer step is intermolecular. Further mechanistic studies revealed a significant positive nonlinear effect, proposed to arise from the selective formation of the [Cu((S,S)-Ph-pybox)((R,R)-Ph-pybox)](SbF6)2 2:1 ligand:metal complex. A stereochemical model is presented in which chelation of (benzyloxy)acetaldehyde to the metal center to form a square pyramidal copper intermediate accounts for the observed sense of induction. Support for this proposal has been obtained from double stereodifferentiating reactions, EPR spectroscopy, ESI spectrometry, and, ultimately, the X-ray crystal structure of the aldehyde bound to the catalyst. The C2-symmetric bis(oxazolinyl)−Cu(II) complex [Cu((S,S)-tert-Bu-box)](OTf)2 is also an efficient catalyst for the aldol reaction, but the scope with this system is not as broad.
Preparation of a microcrystalline suspension formulation of LysB28ProB29‐human insulin with ultralente properties (1999)

The monomeric analogue, Lys(B28)Pro(B29)-human insulin (LysPro), has been crystallized using similar conditions employed to prepare extended-acting insulin ultralente formulations. In the presence of zinc ions, sodium acetate and sodium chloride, but without phenolic preservative, LysPro surprisingly forms small rhombohedral crystals with similar morphology to human insulin ultralente crystals with a mean particle size of 20 +/- 1 microm. X-ray powder diffraction studies on the LysPro crystals prior to dilution in ultralente vehicle ([NaCl] = 1.2 M) revealed the presence of T(3)R(3)(f) hexamers. Consistent with human insulin ultralente preparations, LysPro crystals formulated as an ultralente suspension ([NaCl] = 0. 12 M) contain T(6) hexamers indicating that a conformational change occurs in the hexamer units of the crystals upon dilution of the salt concentration. The pharmacological properties of subcutaneously administered ultralente LysPro (ULP) were compared to ultralente human insulin (UHI) using a conscious dog model (n = 5) with glucose levels clamped at basal. There were no statistically significant differences between the kinetic and dynamic responses of ULP compared to UHI [C(max) (ng/mL): 3.58 +/- 0.76, ULP and 3.61 +/- 0. 66, UHI; T(max) (min): 226 +/- 30, ULP and 185 +/- 42, UHI; R(max) (mg/kg min): 11.2 +/- 1.9, ULP and 13.3 +/- 2.0, UHI; and T(Rmax) (min): 336 +/- 11, ULP and 285 +/- 57, UHI]. Although the Pro to Lys sequence inversion destabilizes insulin self-assembly and greatly alters the time action of soluble LysPro preparations, this modification has now been found neither to prevent the formation of ultralente crystals in the absence of phenolics nor to compromise the protracted activity of the insulin analogue suspension.
Hot isostatic pressing of powder in tube MgB2 wires (2003)

The critical current density (Jc) of hot isostatic pressed (HIPed) MgB2 wires, measured by dc transport and magnetization, is compared with that of similar wires annealed at ambient pressure. The HIPed wires have a higher Jc than the annealed wires, especially at high temperatures and magnetic fields, and higher irreversibility field (Hirr). The HIPed wires are promising for applications, with Jc&gt;106 A/cm2 at 5 K and zero field and &gt;104 A/cm2 at 1.5 T and 26.5 K, and Hirr∼17 T at 4 K. The improvement is attributed to a high density of structural defects, which are the likely source of vortex pinning. These defects, observed by transmission electron microscopy, include small angle twisting, tilting, and bending boundaries, resulting in the formation of subgrains within MgB2 crystallites.
A LOVE FOR INDONESIA: THE YOUTH'S EFFORT IN INCREASING HONOR TOWARDS MUL TICUL TURALISM (2012)

Indonesia is a country which is full of cultures and diversities. A multicultural country usually finds and faces the same problem that is the internal conflicts and even separation. As the cultured humankind, people should see the diversity of cultures as the wealth of nations and the ancestor's heritage that should be well-kept and developed. 
This study is intended to discuss and analyze the multiculturalism in Indonesia, its development, and what the youth should do as the successor of the country to increase their honor towards multiculturalism as the writer sees that there are many youth who have lost their loyalty to their own cultures.
Ferroelectric Properties of BiFeO<sub>3</sub>Thin Films Prepared via a Simple Chemical Solution Deposition (2010)

Bi1+xFeO3 (BFO, x = 0,0.05,0.1,0.15) thin films are fabricated on LaNiO3 (LNO) buffered Si substrates by using a polymeric precursor solution under appropriate crystallization condition. All films possess highly (100) preference oriented. SEM analyses show that the average grain size decreases and thin films become dense and smoother with increasing of excess Bi content. The enhancement of polarization and improvement of leakage current are observed for BFO thin films with 10% excess Bi content. It indicates that the optimized excess Bi content plays an important role in the microstructure and ferroelectric property for BFO thin films.
Mechanistic Studies of Olefin Metathesis by Ruthenium Carbene Complexes Using Electrospray Ionization Tandem Mass Spectrometry (2000)

The olefin metathesis reaction of the Grubbs ruthenium carbene complexes has been investigated in the gas phase by electrospray ionization tandem mass spectrometry. Relative rates of reaction for substituted ruthenium benzylidenes and alkylidenes after removal of one phosphine ligand were interpreted with the aid of linear free energy analysis and kinetic isotope effects. The experimental observations are consistent with a reaction profile in which the metallacyclobutane structure is a transition state rather than an intermediate, although alternative explanations cannot be wholly ruled out. Electron withdrawal on the carbene moiety is found to accelerate the metathesis reaction when only the metathesis step itself is examined. Quantum chemical calculations at a variety of levels were performed to check for the consistency of the interpretation.
Improving the Performance of Action Prediction through Identification of Abstract Tasks (2003)

An intelligent home is likely in the near future. An important ingredient in an intelligent environment such as a home is prediction of the next action, the next location, and the next task that an inhabitant is likely to perform. In this paper we describe our approach to solving the problem of predicting inhabitant behavior in a smart home. We model the inhabitant actions as states in a simple Markov model, then improve the model by supplying it with data from discovered high-level inhabitant tasks. For simulated data we achieved good accuracy, whereas on real data we had marginal performance. We also investigate clustering of actions and subsequently predict the next action and the task with hidden Markov models created using the clusters.

IMS: Model and calculation method of telecommunication network's capacity (2017)

Solving the problems of convergence networks of various technologies, ensuring their compatibility at the level of control, signaling and traffic flows is connected with bringing the networks in compliance with the requirements of the IMS (IP Multimedia Subsystem) architecture. In the process of network pairing, two main tasks must be solved. The first is the interconnection of networks of different technologies for signaling. The second task is to ensure the interaction of networks at the level of traffic flows. When solving the first task, all kinds of signaling are transferred to the use of the SIP protocol. And when solving the second task, all types of transport streams are transferred to the stack protocols of IP network. All pairing tasks are addressed at the element management level CSCF (Call Session Control Function), P-CSCF (Proxy Call Session Control Function), I-CSCF (Interrogating CSCF), S-CSCF (Serving-CSCF). When designing the IMS management layer, it is necessary to determine the amount of traffic that will be served by CSCF elements. And then calculate the necessary performance of the branches of the telecommunications network to handle the signal and transport load. The article analyzes the functioning of the IMS core in solving the problems of conjugation of transport and signal flows. A list of the main elements involved in the management process has been determined. A model is proposed that allows to calculate the volume of incoming traffic from heterogeneous networks and its value after conversion to a standard form in accordance with the requirements of the IMS architecture. The requirements for the telecommunications component of the IMS architecture are defined.
Synthesis of Some Novel 4-Imino-3,5,7-Trisubstituted Pyrido[2,3-<i>d</i>]Pyrimidine-2(1<i>H</i>)-Thiones and Their Nucleosides as Potential Therapeutic Agents (2000)

Abstract Some newer 4-imino-3,5,7-trisubstituted pyrido[2,3-d]pyrimidine-2(1H)-thiones were synthesized by the condensation of 2-amino-3-cyano-4,6-disubstituted pyridines with phenylisothiocyanate. The nucleosides viz., 4-imino-3,5,7-trisubstituted-1-(2,3,5-tri-O-benzoyl-β-D-ribofuranosyl)pyrido[2,3,-d]pyrimidine-2(1H)-thiones were synthesized by the condensation of trimethylsilyl derivatives of pyrido[2,3-d]pyrimidine with sugar namely β-D-ribofuranose 1-acetare-2,3,5-tribenzonte while 4-imino-3,5,7-trisubstituted-1-(2,3,5-tri-O-benzoyl-α-D-ribofuranosyl)pyrido(2,3-d]pyrimidine-2(1H)-thiones were prepared by condensing trimethylsilyl derivatives of pyrido[2,3-d]-pyrimidine with sugar in presence of SnCl4. All the synthesized nucleosides and their precursors were characterized by spectral and elemental analysis data and have been screened for their antimicrobial activities.
Wireless Sensor Networks for Ecology (2005)

Yang Lake has been capturing the attention of scientists for more than 60 years. The subtropical lake, nearly untouched by humans because of its remote location, experiences typhoons each year and is surrounded by an ancient cypress forest-fertile ground on which limnologists, botanists, and climatologists can conduct long-term studies of its rich environments and ecosystems. A single typhoon can drop more than a meter (m) of precipitation on the 4.5-m-deep lake, doubling its volume in a single day and resulting in rapid flushing. The impacts of this extreme flushing on carbon dynamics, when compared with the dynamics in lakes with longer water retention times, can provide new insights into the effects of extreme events on carbon loading

The implemented system can considerably enhance emotionally immersive experience of real-time messaging.
Inhibition of Copper-Zinc Superoxide Dismutase Induces Cell Growth, Hypertrophic Phenotype, and Apoptosis in Neonatal Rat Cardiac Myocytes In Vitro (1999)

Oxidative stress has been implicated in the pathophysiology of myocardial failure. We tested the hypothesis that inhibition of endogenous antioxidant enzymes can regulate the phenotype of cardiac myocytes. Neonatal rat ventricular myocytes in vitro were exposed to diethyldithiocarbamic acid (DDC), an inhibitor of cytosolic (Cu, Zn) and extracellular superoxide dismutase (SOD). DDC inhibited SOD activity and increased intracellular superoxide in a concentration-dependent manner. A low concentration (1 micromol/L) of DDC stimulated myocyte growth, as demonstrated by increases in protein synthesis, cellular protein, prepro-atrial natriuretic peptide, and c-fos mRNAs and decreased sarcoplasmic reticulum Ca(2+)ATPase mRNA. These actions were all inhibited by the superoxide scavenger Tiron (4,5-dihydroxy-1,3-benzene disulfonic acid). Higher concentrations of DDC (100 micromol/L) stimulated myocyte apoptosis, as evidenced by DNA laddering, characteristic nuclear morphology, in situ terminal deoxynucleotidyl transferase-mediated nick end-labeling (TUNEL), and increased bax mRNA expression. DDC-stimulated apoptosis was inhibited by the SOD/catalase mimetic EUK-8. The growth and apoptotic effects of DDC were mimicked by superoxide generation with xanthine plus xanthine oxidase. Thus, increased intracellular superoxide resulting from inhibition of SOD causes activation of a growth program and apoptosis in cardiac myocytes. These findings support a role for oxidative stress in the pathogenesis of myocardial remodeling and failure.
Tick saliva inhibits differentiation, maturation and function of murine bone‐marrow‐derived dendritic cells (2005)

Haematophagous arthropod vectors such as mosquitoes, tsetse flies, sandflies and ticks have evolved salivary immunomodulatory factors that prevent the vertebrate host from rejecting them meanwhile enhancing pathogen transmission. As dendritic cells (DC) play a major role in host immune responses, we studied the effects of Rhipicephalus sanguineus tick saliva on DC differentiation and maturation. Flow cytometry analysis revealed that the addition of saliva to bone marrow cells inhibits the differentiation of DC and decreased the population of differentiated immature DC, increasing the levels of major histocompatibility complex (MHC) class II while not altering the expression of costimulatory (CD40, CD80 and CD86) and adhesion (CD54) molecules. Furthermore, maturation of DC stimulated by lipopolysaccharide (LPS) in the presence of saliva resulted in a lower expression of costimulatory molecules, but did not alter the up-regulation of MHC class II and CD54. The lipopolysaccharide (LPS)-matured DC cultured with saliva also presented reduced production of interleukin-12, whereas interleukin-10 production was unaltered. Assessment of the function of DC cultured with tick saliva revealed them to be poor stimulators of cytokine production by antigen-specific T cells. Our data indicate a novel modulatory role for the saliva of arthropod vectors at an initial step of the immune response through the inhibition of differentiation and maturation of DC into functional antigen-presenting cells.

Transport Properties in Band-Tails of High Mobility Poly-Si TFTs (1996)

Electrical properties of high-mobility polycrystalline silicon thin film transistors (poly-Si TFTs) are measured over the wide temperature range from 300 K to 1.5 K in order to clarify the role of band-tail states in the grain boundaries (GBs). Two distinct regimes of weak and strong localization of electrical transport have been identified below and above the carrier trap state density N st ≈1.0×10 12 cm -2 in the GBs for high-mobility poly-Si TFTs. Poly-Si TFTs with a smaller carrier trap state density N st (≈6×10 11 cm -2 ) show metallic behavior where the mobility increases as temperature decreases. Poly-Si TFTs with larger N st (≈1.5×10 12 cm -2 ) show semiconducting behavior of mobility. At low temperatures, on the former poly-Si TFT the resistance changes due to the weak-localization effect and on the latter poly-Si TFT due to the variable-range hopping (VRH) in the regime of strong localization. In both regimes, negative magnetoresistances have been observed and interpreted by the quantum interference effect. All of these features are attributed to the band-tail states decaying exponentially from the band-edge, based on the observations of irregular GB structure in the poly-Si film from transmission electron microscope images and the roughness at the SiO 2 /poly-Si interface seen on atomic force microscope images.
