Low-temperature Synthesis of Perovskite Pb(Mg(subscript 1/2)W(subscript 1/2))O3-PbTiO3 via a Hydrothermally Derived Precursor (2010)

Aim To prepare pure perovskite phase Pb (Mg(subscript 1/2) W(subscript 1/2)) O3-PbTiO3 (PMW-PT) ceramics. Methods Powders of PMW-PT precursor were synthesized at temperatures as low as 200℃ by means of hydrothermal synthesis using Mg(Ac)2•4H20, Pb(Ac)2•4H20, Na2WO4•3H2O, and Ti(OC4H9)4 as starting materials. NaOH was used to adjust the pH of the reaction system to values between 9 and 13. Purephase perovskite PMW-PT powders were prepared by calcining the hydrothermally derived compounds. By X-ray diffraction analysis, the influence of the hydrothermal temperature, reaction time, solution pH, and calcination temperature on the formation of the PMW-PT phase and of an intermediate Pb2 TiWO7 phase were investigated. Results The hydrothermally derived powders transformed optimally into perovskite PMW-PT after calcining at 800℃. Compressed ceramics of PMW-PT produced by sintering at 1000℃ for 2 h exhibited a dielectric constant of 12067 at a frequency of 1 kHz. Conclusion Compared with solid-state and semi- chemical methord, perovskite PMW-PT powders are formed at a lower temperature in this synthetic rote and the dielectric constant of the ceramic is higher.
Incorporating a Rapid-Impact Package for Neglected Tropical Diseases with Programs for HIV/AIDS, Tuberculosis, and Malaria (2006)

Hotez et al. argue that achieving success in the global fight against HIV/AIDS, tuberculosis, and malaria may well require a concurrent attack on the neglected tropical diseases.
Sieve: A Java-Based Framework for Collaborative Component Composition (1998)

This thesis investigates the design objectives for a collaborative workspace based on Sun Microsystems' Java programming language and JavaBeans component architecture. The feasibility of a collaborative component workspace based on these objectives is demonstrated by Sieve, a Javabased framework for collaborative applications. Sieve allows multiple users to collaboratively add, edit, and connect components on a shared two-dimensional workspace. Sieve introduces a technique that leverages standard JavaBeans mechanisms to support use of \collaboration-unaware" software components. With this technique, components need only conform to basic JavaBeans conventions in order to be shared across collaborating sessions { they need not be programmed specifically for collaboration. Sieve also allows component developers to provide custom mechanisms for sharing components. Sieve is extensible in other ways, allowing developers to introduce new mechanisms for creating, displaying, editing, and connecting components. Three collaborative applications built on this framework are presented: a visualization environment, a circuit simulation, and a set of tools for composing arbitrary software components. The visualization environment allows construction of dataflow networks from an extensible set of modules. Modules may read data from a variety of sources, filter and transform the data in various ways, and generate visualizations. The circuit simulation allows users to collaboratively construct and analyze simple direct-current circuits. Finally, the \BeanBox Emulation" application reproduces the basic component-linking functionality of Sun's BeanBox builder tool. With this application, users may collaboratively edit and link objects that conform to standard JavaBeans conventions.
High power coherent two-dimensional semiconductor laser array (1994)

Diffraction limited 1.4 W pulsed output power is demonstrated from a two-dimensional 144 element surface emitting laser array placed in an external Talbot cavity. Phase locking of the array is achieved with a parallel phase sensing and control system based on phase contrast imaging used in combination with a liquid crystal array in the laser cavity. Diffraction limited cw operation is also demonstrated.
Center Effects in Hospital Mortality of Critically Ill Patients With Hematologic Malignancies* (2019)

Between-center heterogeneity in hospital mortality was confirmed after adjustment for individual prognostic factors. It was partially explained by center experience in treating oncology patients. Interestingly, center effect was similar in magnitude to that of known mortality risk factors.
Disproportion of lamellar capillary non-perfusion in proliferative diabetic retinopathy on optical coherence tomography angiography (2019)

Three-dimensional assessment of wide-field OCTA promotes a better understanding of the enigmatic disproportion of lamellar NPAs in the posterior pole in PDR.
Relation Between the Efficiency of Homothallic Switching of Yeast Mating Type Genes and the Distribution of Cell Types (1981)

Homothallic switching of yeast mating type genes occurs as often as each cell division, so that a colony derived from a single haploid spore soon contains an equal number of MATa and MAT alpha cells. Cells of opposite mating types conjugate, and eventually the colony contains only nonmating MATa/MAT alpha diploids. Mutations that reduce the efficiency of homothallic MAT conversions yield colonies that still contain many haploid cells of the original spore mating type plus a few recently generated cells of the opposite mating type. These (a greater than alpha)- or (alpha greater than a)-mating colonies also contain some nonmating diploid cells. As an alternative to microscopic pedigree analysis to determine the frequency of mating type conversions in a variety of mutant homothallic strains, we analyzed the proportions of MATa, MAT alpha, and MATa/MAT alpha cells in a colony by examining the mating phenotypes of subclones. We developed a mathematical model that described the proportion of cell types in a slow-switching colony. This model predicted that the proportion of nonmating cells would continually increase with the size (age) of a colony derived from a single cell. This prediction was confirmed by determining the proportion of cell types in colonies of an HO swi1 strain that was grown for different numbers of cell divisions. Data from subcloning (a greater than alpha) and (alpha greater than a) colonies from a variety of slow-switching mutations and chromosomal rearrangements were used to calculate the frequency of MAT conversions in these strains.
Phakefustatins A–C: Kynurenine-Bearing Cycloheptapeptides as RXRα Modulators from the Marine Sponge Phakellia fusca (2020)

A neutral-loss scanning mass method was used to explore new kynurenine-containing cycloheptapeptides, phakefustatins A-C (<b>1</b>-<b>3</b>), from the marine sponge <i>Phakellia fusca</i>. Their structures were elucidated by spectroscopic analysis and the advanced Marfey's method. <b>1</b> was total synthesized via a final-stage ozonolysis strategy by the combination of solid/solution-phase synthesis. Phakefustatin A (<b>1</b>) was identified as a RXRα modulator to inhibit cancer cell growth, and its pharmacophores could be Kyn and guanidine groups.
Impaired endogenous fibrinolysis at high shear using a point-of-care test in STEMI is associated with alterations in clot architecture (2019)

Impaired endogenous fibrinolysis is an adverse prognostic biomarker in acute coronary syndrome (ACS). Abnormally dense in vitro fibrin thrombi have been demonstrated in ACS patients and related to hypofibrinolysis using cumbersome, laboratory-based methods. We aimed to assess endogenous fibrinolysis using a point-of-care technique and relate this to clot architecture. From patients with ST-segment elevation myocardial infarction (STEMI), venous blood was drawn immediately on arrival to assess thrombotic status. Blood was assessed using the point-of-care Global Thrombosis Test which measures occlusive thrombus formation under high shear and subsequently endogenous fibrinolysis (lysis time, LT). Two samples per patient were run in parallel. In one channel, the measurement was allowed to proceed as normal. In the other, after occlusion, thrombus was extracted, washed, fixed in glutaraldehyde, dried, sputter-coated, and assessed using scanning electron microscope. Endogenous fibrinolysis was strongly associated fibrin fibre thickness (p = 0.0001). As LT increased (less efficient fibrinolysis), the fibrin network of the thrombus was significantly more compact and dense, with thinner fibrin fibres and smaller gaps. Fibrin fibre thickness correlated inversely with LT (r = - 0.89, p = 0.001). Adverse clot architecture in vitro is directly related to impaired endogenous fibrinolysis using a relatively new point-of-care technique in patients with STEMI. This may transform the relevance of fibrin clot architecture from an off-line laboratory association to being directly relevant to endogenous fibrinolysis at the patient bedside, which could be used as a near-patient test to guide prognosis and assess the effect of treatment.
Using the Contact and Channel Model for the methodical development of lightweight Solutions (2012)

In literature there are several lightweight approaches, such as conditional, conceptual or material lightweight design. But the challenge for the designers is to use the suitable lightweight approach and to develop a lightweight solution for their product. In this paper, an approach for a method which supports the designer in a systematic finding of lightweight solutions will be presented. In order to realise a method for developing lightweight solutions, the Contact & Channel - Model will be adapted.
Applicability of Different Antibodies for the Immunohistochemical Localization of CFTR In Respiratory and Intestinal Tissues of Human and Murine Origin (2003)

Cystic fibrosis (CF) is caused by mutations in the gene encoding the CF transmembrane conductance regulator (CFTR) protein, which has a major role as a chloride (Cl(-)) channel. Although perhaps all functions of CFTR are still not fully characterized, localization studies are necessary to understand the consequences of the more than 1000 mutations thus far identified. Our aim was to determine the histological localization of CFTR on respiratory and colon epithelia of human and murine origin with a panel of several antibodies produced against different CFTR epitopes, using an indirect immunofluorescence method. Our results on human tissues confirm the apical localization of CFTR in ciliated cells of the respiratory mucosa and show that in colon tissue CFTR is observed in both apical and basolateral membranes of epithelial cells from colon crypts. However, poor tissue preservation of colon biopsies after immunohistochemistry (IHC) raises doubts about the latter localization. Contrary to human, mouse colon epithelium (not biopsed) presents good tissue preservation and evidences many cylindrical surface cells with high apical expression of CFTR. For the antibodies' sensitivity, we demonstrate that MATG1061, 24-1, M3A7, and MPCT-1 give good results, allowing the histological localization of CFTR protein of both human and murine origin.
TIME-RESOLVED VELOCITY PROFILES BY VIBRATIONAL TAGGING OF OXYGEN (1987)

Raman Excitation + Laser-Induced Electronic Fluorescence (RELIEF) has been used to instantaneously measure three-dimensional velocity profiles and structure in air and oxygen. No seeding of particles, molecules, or atomic species is required.
Multiresponse parameter estimation and compartmental analysis of time resolved fluorescence spectra. Application to conformational dynamics of charge-separated species in solution (1993)

2 Lecture conformational changes of intramol. charge-transfer species were studied by means of time resolved fluorescence spectroscopy. From a time resolved fluorescence spectrum the parameters which describe a kinetic, compartmental, model as well as the model dependent fluorescence spectral-shape parameters were estd. Two methods for parameter estn. were compared nonlinear least squares and multiresponse. Anal. of residuals revealed shortcomings of the exptl. setup, in particular time jitter. The concn. fluctuations induced by this time jitter could cause failure of the usual nonlinear least squares model fit, whereas the multiresponse parameter estn. was successful. Different compartmental models with the same kinetic parameters result in identical residuals. Thus a distinction can only be made on the basis of the accompanying estd. spectra. Due to the restriction that fluorescence spectra are nonneg., the anal. of a two-component system was only satisfactory using a model in which a slower decaying component was a reaction product of a faster decaying component. A three-component system was satisfactorily described by a model with three independently decaying components.
Auto-detection of arch curve from dental meshes (2016)

Building the form of dental arch is of great importance for orthodontic diagnosis and treatment. This paper presents a novel automated method for detecting the arch curve from dental triangular meshes with minimal user intervention. The feature region between gingiva and teeth were firstly extracted based on discrete curvature analysis. Then using the feature region as reference, a feature image were generated where the arch skeleton is detected. The arch curve were finally computed to approximate the skeleton line based on B-spline extended fitting. The experiment results demonstrate that the method is fast and robust even in the presence of malocclusion.
Classical Metallocenes as Photoinitiators for the Anionic Polymerization of an Alkyl 2-Cyanoacrylate (2002)

The classical metallocenes, ferrocene and ruthenocene, dissolve readily in neat ethyl 2-cyanoacrylate (CA) monomer. The electronic spectra of the resulting solutions display a near-ultraviolet absorption band assigned as a charge-transfer-to-solvent (metallocene → CA) transition. Irradiation into this band causes the one-electron oxidation of the metallocene to the corresponding metallocenium cation accompanied by reduction of CA to its radical anion. Addition of the latter species to CA initiates the anionic polymerization of the electrophilic monomer. The progress of photoinitiated polymerization was monitored in real time by attenuated total reflectance infrared spectroscopy.
Italian translation, cultural adaptation, and pilot testing of a questionnaire to assess family burden in inherited ichthyoses (2019)

The Italian version of the FBI generated in the present study is a useful instrument to measure the impact of ichthyosis on family daily life, education and working activities, psychological implications, and the disease economic load. The questionnaire will be further validated through a multicenter Italian study on burden of ARCI. A validated Italian questionnaire is a valuable tool for future clinical trials. In addition, it can be used to rapidly identify family distressing situations, which require attention and prompt intervention.
Probabilities for opportunistic networking in different scenarios (2012)

Opportunistic Networks (ONs) can be defined as temporary, operator-governed, coordinated extension of the infrastructure. These opportunistic networks can be used for extending the coverage of cellular networks, for offloading traffic from cellular networks by using direct connections between the devices or for opportunistic capacity extensions. While work has already been made or is ongoing on how to create and maintain such opportunistic networks, this paper analyses the probabilities that such opportunistic networks can be established and maintained in the different scenarios.
Thin-Film Optical Filters (2001)

Very common optical coatings are those that give the faint, reflected color to the lenses in cameras, binoculars, and spectacles. The thin metal layer that makes the difference between a mirror and a simple sheet of glass is an optical coating. But, optical coatings are used in many more applications-a particularly important current one being the s
Conserved features of Y RNAs revealed by automated phylogenetic secondary structure analysis (1999)

Y RNAs are small 'cytoplasmic' RNAs which are components of the Ro ribonucleoprotein (RNP) complex. The core of this complex, which is found in the cell nuclei of higher eukaryotes as well as the cytoplasm, is composed of a complex between the 60 kDa Ro protein and Y RNAs. Human cells contain four distinct Y RNAs (Y1, Y3, Y4 and Y5), while other eukaryotes contain a variable number of Y RNA homologues. When detected in a particular species, the Ro RNP has been present in every cell type within that particular organism. This characteristic, along with its high conservation among vertebrates, suggests an important function for Ro RNP in cellular metabolism; however, this function has not yet been definitively elucidated. In order to identify conserved features of Y RNA sequences and structures which may be directly involved in Ro RNP function, a phylogenetic comparative analysis of Y RNAs has been performed. Sequences of Y RNA homologues from five vertebrate species have been obtained and, together with previously published Y RNA sequences, used to predict Y RNA secondary structures. A novel RNA secondary structure comparison algorithm, the suboptimal RNA analysis program, has been developed and used in conjunction with available algorithms to find phylogenetically conserved secondary structure models for YI, Y3 and Y4 RNAs. Short, conserved sequences within the Y RNAs have been identified and are invariant among vertebrates, consistent with a direct role for Y RNAs in Ro function. A subset of these are located wholly or partially in looped regions in the Y3 and Y4 RNA predicted model structures, in accord with the possibility that these Y RNAs base pair with other cellular nucleic acids or are sites of interaction between the Ro RNP and other macromolecules.
Correlation of chemistry with normal albedo in the Crisium region (1978)

The region in the vicinity of the Luna 24 handling site (40-70 deg E; 0-20 deg N) is studied by means of the Apollo orbital fluorescent X-ray Al/Si and Mg/Al data and earth-based normal albedo measurements. By means of unsupervised non-parametric cluster analysis this region is divided into eight surface units. One of these units centered in the Proclus region deviates from the usual trend of increasing normal albedo with increasing Al/Si values and decreasing Mg/Al values
Insulin action on the glucose transport system in isolated cardiocytes from adult rat (1983)

Calcium-tolerant myocytes from the adult rat heart were used to study the effects of insulin on the kinetics of myocardial 3-0-methylglucose transport at 37 degrees C. Insulin increased the initial velocity of sugar influx without affecting the equilibrium uptake values. Maximal stimulation averaged 50-80%, with a half-maximal response at an insulin concentration of 0.1 nM and maximal stimulation occurring at 1 nM. The onset of insulin action was preceded by a lag-phase of 20 s, reaching maximal action by 60 s. The Vmax. of the glucose transport system was increased from 160 to 287 nmol/min per 10(6) cells with an unaltered affinity. Neither extracellular nor intracellular calcium was found to be involved in the stimulatory action of insulin. Removal of intracellular magnesium resulted in a loss of insulin action. This study demonstrates that activation of the cardiac glucose transporter by insulin is due exclusively to an increase in the maximal velocity representing one of the very early effects of insulin on myocardial metabolism. The data suggest involvement of magnesium in the transmission of the insulin signal.
Synthesis of Size-and-Shape-Controlled Iron Oxide Nanoparticles via Coprecipitation and In Situ Magnetic Separation (2022)

The purpose of this study was to determine the effect of in situ magnetic separation on the size and shape of iron oxide nanoparticles produced through coprecipitation. A batch reactor system was equipped with a magnetic array comprising neodymium magnets, providing a weak static magnetic field. Iron chloride and sodium hydroxide solutions were contacted at room temperature, producing an iron oxide precipitate. The magnetic array was able to rapidly remove the as-formed iron oxide nanoparticles from the reaction front and prevent further growth and agglomeration, therefore serving as a facile method of controlling the size and shape of the product. Mechanical agitation did not favor this effect, as it resulted in transfer of the precipitating agent from regions of high to low concentration, promoting growth and agglomeration. The method is attractive for large-scale production of iron oxide nanoparticles requiring tuned size and morphology.
Polarized edge emission from GaN-based light-emitting diodes sandwiched by dielectric/metal hybrid reflectors (2010)

Edge-emitting c-plane GaN/sapphire-based light-emitting diodes (LEDs) sandwiched by two dielectric/metal hybrid reflectors on both sapphire and GaN surfaces were studied to determine their light emission polarization. The hybrid reflectors comprised dielectric multiple thin films and a metal layer. The metal layers of Au or Ag used in this study were designed to enhance the polarization ratio from S-polarization (transverse electric wave, TE) to P-polarization (transverse magnetic wave, TM). The two sets of optimized dielectric multi thin films served as matching layers for wide-angle incident light on both sapphire and GaN surfaces. To determine which reflector scheme would achieve a higher polarization ratio, simulations of the reflectance at the hybrid reflectors on sapphire (or GaN) interface were performed before the fabrication of experimental LEDs. Compared with conventional c-plane InGaN/GaN/sapphire LEDs without dielectric/metal hybrid reflectors, the experimental LEDs exhibited higher polarization ratio (ITE-max/ITM-max) with r=2.174 (∼3.37 dB) at a wavelength of 460 nm. In contrast, the original polarized light (without dielectric/metal hybrid reflectors) was partially contributed (r=1.398) by C-HH or C-LH (C band to the heavy-hole sub-band or C band to the crystal-field split-off sub-band) transitions along the a-plane or m-plane direction.
Address-Value Delta (AVD) Prediction: A Hardware Technique for Efficiently Parallelizing Dependent Cache Misses (2006)

While runahead execution is effective at parallelizing independent long-latency cache misses, it is unable to parallelize dependent long-latency cache misses. To overcome this limitation, this paper proposes a novel hardware technique, address-value delta (AVD) prediction. An AVD predictor keeps track of the address (pointer) load instructions for which the arithmetic difference (i.e., delta) between the effective address and the data value is stable. If such a load instruction incurs a long-latency cache miss during runahead execution, its data value is predicted by subtracting the stable delta from its effective address. This prediction enables the preexecution of dependent instructions, including load instructions that incur long-latency cache misses. We analyze why and for what kind of loads AVD prediction works and describe the design of an implementable AVD predictor. We also describe simple hardware and software optimizations that can significantly improve the benefits of AVD prediction and analyze the interaction of AVD prediction with runahead efficiency techniques and stream-based data prefetching. Our analysis shows that AVD prediction is complementary to these techniques. Our results show that augmenting a runahead processor with a simple, 16-entry AVD predictor improves the average execution time of a set of pointer-intensive applications by 14.3 percent (7.5 percent excluding benchmark health).
