A one step annealing for dopants activation, silicide resistivity lowering and glass flow by rapid thermal processing (2003)

A method to achieve titanium silicide resistivity lowering, dopants activation, and glass reflow in a one-step rapid thermal annealing (RTA) was developed with the objective of minimizing the thermal degradation of the silicide layer. It is found that the resistivity of TiSi/sub 2/ after high-temperature RTA essentially depends on whether or not the surface layer, which is formed during the first RTA in nitrogen ambient, was selectively removed before PSG deposition and reflow. With this protection film, a sheet resistance lower than 2 Omega /square. On the gate and diffusion areas was obtained. Without it, a considerable resistivity increase is observed. The barrier effect of this nitride layer is believed to be primarily responsible for this better stability. The efficiency of the method is demonstrated in a 1.5- mu m polycide process.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A comparison of two types of vacuum drainage after cholecystectomy. (1984)

Following cholecystectomy, 50 patients were randomly allocated for suction drainage by small (2.5 mm) Redivac or large calibre (6 mm) Redivac drains. There were 25 patients in each group. Subhepatic collection was detected by ultrasonic examination in 5 patients on the seventh postoperative day. The smaller drain was used in all of these patients. Of these 5 patients, one developed pulmonary infection, a second had internal bleeding requiring laparotomy, while the remaining 3 were asymptomatic. Subhepatic fluid was not detected in any patient who had the larger drain.
[Psychogenic growth retardation. Critical study of diagnostic data]. (1987)

The diagnosis of psychosocial deprivation dwarfism is difficult. It is also of practical importance since it leads to the only one appropriate treatment: the decision to send the child in a new environment, foster institution or foster family. The present work reports the clinical, biological and psychologic characteristics of 34 children and adolescents aged 9 months to 17 years, in whom a severe growth deficiency had been considered as probably related to psychosocial deprivation, and who were thus sent in foster institutions with good medical and psychological support. The result was in 24 cases a sharp increase of growth rate, giving confirmation of the diagnosis suspected, and in 10 a failure, making this diagnosis unlikely. A comparison of these two groups does not demonstrate any significantly different criterion. The conclusion suggested is thus the following: a trial of at least three months in a foster home, decided on concordant clinical and psychological data, without regard to the biological data, is the only way for distinguishing the truly and falsely deprivation-related dwarfism, or at least to give appropriate support for long-term therapeutic decisions.
Reduced Gastrointestinal Absorption of Calcium in Dementia (1990)

Several reports have suggested that the neurodegenerative change in Alzheimer-type dementia (ATD) may be related to alterations in calcium homoeostasis. The absorption of radiocalcium (45Ca) in 26 ATD subjects and 11 patients with multi-infarct dementia (MID) was compared to 24 normal age- and sex-matched controls. The absorption of radiocalcium was significantly lower in both ATD and MID when compared to controls. The reduced 45Ca absorption in ATD occurred in the presence of normal plasma concentrations of PTH and vitamin D metabolites and the serum concentrations of calcium and aluminium were in the normal range. The data suggest that the reduced uptake of radioactive calcium observed in ATD is a non-specific derangement.
Level-k Auctions: Can a Nonequilibrium Model of Strategic Thinking Explain the Winner's Curse and Overbidding in Private-Value Auctions? (2007)

This paper proposes a structural nonequilibrium model of initial responses to incomplete-information games based on “level-k” thinking, which describes behavior in many experiments with complete-information games. We derive the model's implications in first- and second-price auctions with general information structures, compare them to equilibrium and Eyster and Rabin's (2005) “cursed equilibrium,” and evaluate the model's potential to explain nonequilibrium bidding in auction experiments. The level-k model generalizes many insights from equilibrium auction theory. It allows a unified explanation of the winner's curse in common-value auctions and overbidding in those independent-private-value auctions without the uniform value distributions used in most experiments.
Clock synchronization using maximal multipartite entanglement (2012)

We propose a multiparty quantum clock synchronization protocol that makes optimal use of the maximal multipartite entanglement of GHZ-type states. To realize the protocol, different versions of maximally entangled eigenstates of collective energy are generated by local transformations that distinguish among different groupings of the parties. The maximal sensitivity of the entangled states to time differences between the local clocks can then be accessed if all parties share the results of their local time-dependent measurements. The efficiency of the protocol is evaluated in terms of the statistical errors in the estimation of time differences and the performance of the protocol is compared to alternative protocols proposed previously.
The Na<sup>+</sup>‐dependent <scp>l</scp>‐ascorbic acid transporter SVCT2 expressed in brainstem cells, neurons, and neuroblastoma cells is inhibited by flavonoids (2008)

Ascorbic acid (AA) is best known for its role as an essential nutrient in humans and other species. As the brain does not synthesize AA, high levels are achieved in this organ by specific uptake mechanisms, which concentrate AA from the bloodstream to the CSF and from the CSF to the intracellular compartment. Two different isoforms of sodium-vitamin C co-transporters (SVCT1 and SVCT2) have been cloned. Both SVCT proteins mediate high affinity Na(+)-dependent L-AA transport and are necessary for the uptake of vitamin C in many tissues. In the adult brain the expression of SVCT2 was observed in the hippocampus and cortical neurons by in situ hybridization; however, there is no data regarding the expression and distribution of this transporter in the fetal brain. The expression of SVCT2 in embryonal mesencephalic neurons has been shown by RT-PCR suggesting an important role for vitamin C in dopaminergic neuronal differentiation. We analyze SVCT2 expression in human and rat developing brain by RT-PCR. Additionally, we study the normal localization of SVCT2 in rat fetal brain by immunohistochemistry and in situ hybridization demonstrating that SVCT2 is highly expressed in the ventricular and subventricular area of the rat brain. SVCT2 expression and function was also confirmed in neurons isolated from brain cortex and cerebellum. The kinetic parameters associated with the transport of AA in cultured neurons and neuroblastoma cell lines were also studied. We demonstrate two different affinity transport components for AA in these cells. Finally, we show the ability of different flavonoids to inhibit AA uptake in normal or immortalized neurons. Our data demonstrates that brain cortex and cerebellar stem cells, neurons and neuroblastoma cells express SVCT2. Dose-dependent inhibition analysis showed that quercetin inhibited AA transport in cortical neurons and Neuro2a cells.
A New Route for Installing the Isocyclic Ring on Chlorins Yielding 13<sup>1</sup>-Oxophorbines (2006)

A new route to 13(1)-oxophorbines, the parent macrocycle of chlorophylls, begins with the synthesis of a 13-bromochlorin. Pd-mediated coupling of the latter with tributyl(1-ethoxyvinyl)tin and subsequent acidic hydrolysis afforded the 13-acetylchlorin (1). Treatment of 1 with NBS afforded the 15-bromo analogue in 70% yield. Pd-mediated alpha-arylation closed the isocyclic ring to give the 13(1)-oxophorbine (2) in 85% yield. Facile access to 13(1)-oxophorbines should enable a variety of spectroscopic studies and diverse applications.
Grime's Graves: Floors 47 to 59 (1920)

By the very kind permission of the owners, I was enabled to carry out the excavation of some “floors” at Grime's Graves, in June and July, 1919, with some friends. At the same time Mr. D. Richardson was clearing the remarkable site which he discovered in the North Field. The centre of Floor 52 was fifty paces N.E. of the corner of the West Field, and fourteen from the edge of the cart track north of the wood. Twenty yards N.W. of the said centre was Floor 47, nearer to the cart track coming up out of the valley, and with comparatively small flakes and cores, of poor quality. The facets are short, deep, and wide, like those on an implement of the Chelles Period. The shapes of the cores differ from the true Grime's Graves type. At Floor 51 Mr. W. G. Clarke rightly pointed out that these traits were, in part, due to the fact that wall-stone was used. Only in part, however, for floor-stone was also used, as examination showed. The chipped flints in the outer part of Floor 47 lay in the lower part of the humus, 9 ins. below the surface.
Fasting Serum Level of Fatty-Acid-Binding Protein 4 Positively Correlates With Metabolic Syndrome in Patients With Coronary Artery Disease (2010)

Among CAD patients in the present study, the fasting level of FABP4 positively correlated with MetS and serum levels of FABP4 correlated with a number of MetS criteria.
Identification of residues in TIP47 essential for Rab9 binding (2002)

TIP47 (tail-interacting protein of 47 kDa) binds to the cytoplasmic domains of the cation-dependent and cation-independent mannose 6-phosphate receptors (MPRs) and is required for their transport from endosomes to the trans-Golgi network in vitro and in living cells. TIP47 recognizes distinct determinants in the cytoplasmic domains of these two receptors, and its ability to bind to the cation-independent MPR is enhanced by the concomitant binding of the Rab9 GTPase. We show here that TIP47 residues 161-169 are essential, but likely not sufficient, for Rab9 binding. Mutation of these residues led to a significant decrease in Rab9 binding, but did not alter the global folding of the protein. The most impaired mutant was indistinguishable from wild-type TIP47 in its circular dichroism spectrum, and mutant proteins that showed decreased Rab9 binding retained full capacity to bind to MPR cytoplasmic domains. Closely related sequences in a related protein, adipophilin, did not confer Rab9 binding capacity to that protein. Partial proteolysis of TIP47 and TIP47 mutant proteins revealed subtle conformational differences, suggesting that residues 161-169 reside in a portion of TIP47 that is important for its conformation. These experiments reveal distinct binding domains for the Rab9 GTPase and MPR cytoplasmic domains in the cargo selection protein TIP47.
Virus and Autoantigen-Specific CD4+ T Cells Are Key Effectors in a SCID Mouse Model of EBV-Associated Post-Transplant Lymphoproliferative Disorders (2014)

Polyclonal Epstein-Barr virus (EBV)-infected B cell line (lymphoblastoid cell lines; LCL)-stimulated T-cell preparations have been successfully used to treat EBV-positive post-transplant lymphoproliferative disorders (PTLD) in transplant recipients, but function and specificity of the CD4+ component are still poorly defined. Here, we assessed the tumor-protective potential of different CD4+ T-cell specificities in a PTLD-SCID mouse model. Injection of different virus-specific CD4+ T-cell clones showed that single specificities were capable of prolonging mouse survival and that the degree of tumor protection directly correlated with recognition of target cells in vitro. Surprisingly, some CD4+ T-cell clones promoted tumor development, suggesting that besides antigen recognition, still elusive functional differences exist among virus-specific T cells. Of several EBV-specific CD4+ T-cell clones tested, those directed against virion antigens proved most tumor-protective. However, enriching these specificities in LCL-stimulated preparations conferred no additional survival benefit. Instead, CD4+ T cells specific for unknown, probably self-antigens were identified as principal antitumoral effectors in LCL-stimulated T-cell lines. These results indicate that virion and still unidentified cellular antigens are crucial targets of the CD4+ T-cell response in this preclinical PTLD-model and that enriching the corresponding T-cell specificities in therapeutic preparations may enhance their clinical efficacy. Moreover, the expression in several EBV-negative B-cell lymphoma cell lines implies that these putative autoantigen(s) might also qualify as targets for T-cell-based immunotherapy of virus-negative B cell malignancies.
NinjaMail: the design of a high-performance clustered, distributed e-mail system (2002)

In today's Internet era, electronic mail is replacing telephony and postal mail as the primary means of communication for hundreds of millions of individuals. Free e-mail services, such as Microsoft's Hotmail and Yahoo's Yahoo Mail, each have tens of millions of subscribers. However, these and other current e-mail systems unfortunately are nor capable of handling the scale of Internet e-mail use, while still providing reliable, high performance and feature-rich services to users. This limitation is the result both of suboptimal use of cluster computing resources, and of highly variable performance of wide-area connections over the Internet. This paper presents NinjaMail, a novel geographically distributed, cluster-based e-mail system built on top of UC Berkeley's Ninja cluster architecture and OceanStore wide-area data storage architecture. NinjaMail is unique in that it uses a collection of clusters distributed through the wide-area to provide users with highly available, scalable and feature-rich services via a wide variety of access methods.
Near-Infrared Irradiation Nonthermally Induces Long-lasting Vasodilation by Causing Apoptosis of Vascular Smooth Muscle Cells. (2011)

Near-infrared irradiation nonthermally induces long-lasting vasodilation by causing apoptosis of vascular smooth muscle cells. Since solar near-infrared radiation nonthermally induces damage of the subcutaneous tissues, exposed skin should be protected with sunscreens that block not only ultraviolet but also near-infrared radiation.
Change from Metastable Cubic to Stable Tetragonal Form of Submicron Barium Titanate (1974)

Abstract The change from metastable cubic to stable tetragonal form was investigated on the submicron BaTiO3 which was prepared by the hydrolysis of titanium tetraisopropoxide in barium hydroxide solution and by crystallization in the glass of BaO–TiO2–SiO2–Al2O3 system. The precipitated BaTiO3 was found to be the aggregates of minute grains of about 100 Å, to have large amount of strain and to absorb about 6% of OH and alcoholic radicals, some of them absorbed chemically. It is in a metastable cubic form. After the heating above 800 °C, it changed to stable tetragonal form in association with weight loss and decrease in lattice strain. The samples heated at 800–900 °C did not show the Curie point on the DTA curve although they were tetragonal. The samples heated at 1300 °C had the Curie point about 122 °C. The glass-devitrified BaTiO3 was also cubic and had large lattice strain. In order to change to tetragonal form, the heating above 1000 °C was needed. The metastable cubic form of submicron BaTiO3 seemed to be stabilized by the absorbants on the surface which balanced with large amount of strain in the lattice.
High-bandwidth uni-traveling carrier waveguide photodetector on an InP-membrane-on-silicon platform (2016)

A uni-traveling carrier photodetector (UTC-PD), heterogeneously integrated on silicon, is demonstrated. It is fabricated in an InP-based photonic membrane bonded on a silicon wafer, using a novel double-sided processing scheme. A very high 3 dB bandwidth of beyond 67 GHz is obtained, together with a responsivity of 0.7 A/W at 1.55 μm wavelength. In addition, open eye diagrams at 54 Gb/s are observed. These results promise high speed applications using a novel full-functionality photonic platform on silicon.

Three-dimensional image analysis and display by space-scale matching of cross sections (1989)

We present a framework and a set of techniques for the analysis and display of three-dimensional experimental data or images. We assume that the data are available in the form of two-dimensional cross sections of the three-dimensional data set. We describe our approach, which has for goals to extract significant information from the three-dimensional data set and to display this information as objects that can be manipulated in three-dimensional space. The high-contrast transitions of two-dimensional cross sections are extracted first; they define a set of contours to be matched from cross section to cross section. This matching is performed by space-scale analysis of the orientation of contours on adjacent cross sections. By modeling the contours as B splines, we then make use of three-dimensional B-spline patches to generate significant surfaces that can be displayed, rendered, and rotated with standard computer graphics techniques and specialized processors.
Novel porous solids for carbon dioxide capture (2011)

Herein, we focus on the latest advances in novel porous solids as highly effective adsorbents for CO2 capture. The advantages and existing barriers of each porous material and their future perspectives will be discussed.
Intraductal Optical Coherence Tomography for Investigating Main Pancreatic Duct Strictures (2006)

This pilot study showed that OCT is feasible during ERCP, in cases of MPD segmental stricture, and was superior to brush cytology in distinguishing nonneoplastic from neoplastic lesions.
Interchain cysteine bridges control entry of progesterone to the central cavity of the uteroglobin dimer (1992)

The progesterone-binding protein uteroglobin has been expressed in Escherichia coli in an unfused, soluble form. Like mature uteroglobin from rabbit endometrium (UG), the E.coli produced uteroglobin (UG1) dimerizes in vitro, forms an antiparallel dimer with Cys3-Cys69' and Cys69-Cys3' disulfide bonds and binds progesterone under reducing conditions. In order to analyze the dimerization and the reduction dependence of progesterone binding in more detail, we separately replaced cysteine 3 and cysteine 69 by serines. Under reducing conditions, both uteroglobin variants (UG1-3Ser and UG1-69Ser) bind progesterone with the same affinity as the wild-type suggesting that both cysteine residues are not directly involved in progesterone binding. In contrast to the wild-type protein, both cysteine variants also bind progesterone with high affinity in the absence of reducing agents. In addition, UG1-3Ser and UG1-69Ser both form covalently linked homodimers. Thus, unnatural Cys69-69' and Cys3-3' disulfide bonds exist in UG1-3Ser and UG1-69Ser, respectively. These data together with computer models based on X-ray diffraction data strongly support the idea that progesterone reaches its binding site located in an internal hydrophobic cavity via a hydrophobic tunnel along helices 1 and 4. Under non-reducing conditions the tunnel is closed by two disulfide bridges (Cys3-Cys69' and Cys69-Cys3') that lie in the most flexible region of the dimer. Reduction or replacement of a cysteine residue enables conformational changes that open the channel allowing progesterone to enter.
Proposal of the genus Sphingomonas sensu stricto and three new genera, Sphingobium, Novosphingobium and Sphingopyxis, on the basis of phylogenetic and chemotaxonomic analyses. (2001)

Phylogenetic analyses of 16S rRNA gene sequences by distance matrix and parsimony methods indicated that the currently known species of the genus Sphingomonas can be divided into four clusters. Some chemotaxonomic and phenotypic differences were noted among these clusters. Three new genera, Sphingobium, Novosphingobium and Sphingopyxis, are proposed in addition to the genus Sphingomonas sensu stricto. The genus Sphingobium is proposed to accommodate Sphingomonas chlorophenolica, Sphingomonas herbicidovorans and Sphingomonas yanoikuyae. The genus Novosphingobium is proposed for Sphingomonas aromaticivorans, Sphingomonas capsulata, Sphingomonas rosa, Sphingomonas stygia, Sphingomonas subarctica and Sphingomonas subterranea. Sphingomonas macrogoltabidus and Sphingomonas terrae are reclassified in the genus Sphingopyxis. The type species of Sphingobium, Novosphingobium and Sphingopyxis are Sphingobium yanoikuyae, Novosphingobium capsulatum and Sphingopyxis macrogoltabida, respectively.
Fast imaging with surface-related multiples by sparse inversion (2015)

In marine exploration seismology, surface-related multiples are usually treated as noise mainly because subsequent processing steps, such as migration velocity analysis and imaging, require multiple-free data. Failure to remove these wavefield components from the data may lead to erroneous estimates for migration velocity or result in strong coherent artefacts that interfere with the imaged reflectors. However, multiples can carry complementary information compared to primaries, as they interact with the free surface and are therefore exposed more to the subsurface. Recent work has shown that when processed correctly multiples can improve seismic illumination. Given a sufficiently accurate background velocity model and an estimate for the source signature, we propose a new and computationally efficient linearized inversion procedure based on two-way wave equations, which produces accurate images of the subsurface from the total upgoing wavefield including surface-related multiples. Modelling of the surface-related multiples in the proposed method derives from the well-known surface-related multiple elimination method. We incur a minimal overhead from incorporating the multiples by having the wave-equation solver carry out the multiple predictions via the inclusion of an areal source instead of expensive dense matrix-matrix multiplications. By using subsampling techniques, we obtain high-quality true-amplitude least-squares migrated images at computational costs of roughly a single reverse-time migration (RTM) with all the data. These images are virtually free of coherent artefacts from multiples. Proper inversion of the multiples would be computationally infeasible without using these techniques that significantly bring down the cost. By promoting sparsity in the curvelet domain and using rerandomization, out method gains improved robustness to errors in the background velocity model, and errors incurred in the linearization of the wave equation with respect to the model. We demonstrate the superior performance of the proposed method compared to the conventional RTM using realistic synthetic examples.
