Organic‐Inorganic Contact Barrier Heights: A Survey of Materials (1986)

Organic‐on‐inorganic semiconductor contact barrier energies have been determined using capacitance and current‐voltage characteristics of several inorganic semiconductor substrate materials. The barrier energies vary from 0.45 eV for n‐type and related compounds under some conditions of surface preparation to 0.85 eV for n‐ and p‐type . These barriers are generally higher than metal/semiconductor Schottky barriers made on the same materials and permit nondestructive analysis and evaluation of the inorganic semiconductor.
Formation of Coelenteramine from 2‐Peroxycoelenterazine in the Ca2+‐Binding Photoprotein Aequorin (2021)

Aequorin consists of apoprotein (apoAequorin) and (S)-2-peroxycoelenterazine (CTZ-OOH) and is considered to be a transient-state complex of an enzyme (apoAequorin) and a substrate (coelenterazine and molecular oxygen) in the enzymatic reaction. The degradation process of CTZ-OOH in aequorin was characterized under various conditions of protein denaturation. By acid treatment, the major product from CTZ-OOH was coelenteramine (CTM), but not coelenteramide (CTMD), and no significant luminescence was observed. The counterparts of CTM from CTZ-OOH were identified as 4-hydroxyphenylpyruvic acid (4HPPA) and 4-hydroxyphenylacetic acid (4HPAA) by liquid chromatography/electrospray ionization-time-of-flight mass spectrometry (LC/ESI-TOF-MS). In the luminescence reaction of aequorin with Ca<sup>2+</sup> , similar amounts of 4HPPA and 4HPAA were detected, indicating that CTM is formed by two pathways from CTZ-OOH through dioxetanone anion and not by hydrolysis from CTMD.
Structure–Conductivity Relationships in Ordered and Disordered Salt-Doped Diblock Copolymer/Homopolymer Blends (2016)

We examine the relationship between structure and ionic conductivity in salt-containing ternary polymer blends that exhibit various microstructured morphologies, including lamellae, a hexagonal phase, and a bicontinuous microemulsion, as well as the disordered phase. These blends consist of polystyrene (PS, Mn ≈ 600 g/mol) and poly(ethylene oxide) (PEO, Mn ≈ 400 g/mol) homopolymers, a nearly symmetric PS–PEO block copolymer (Mn ≈ 4700 g/mol), and lithium bis(trifluoromethane)sulfonamide (LiTFSI). These pseudoternary blends exhibit phase behavior that parallels that of well-studied ternary polymer blends consisting of A and B homopolymers compatibilized by an AB diblock copolymer. The utility of this framework is that all blends have nominally the same number of ethylene oxide, styrene, Li+, and TFSI– units, yet can exhibit a variety of microstructures depending on the relative ratio of the homopolymers to the block copolymer. For the systems studied, the ratio r = [Li+]/[EO] is maintained at 0.06, and the volume fraction of PS homopolymer is kept equal to that of PEO homopolymer plus salt. The total volume fraction of homopolymer is varied from 0 to 0.70. When heated through the order–disorder transition, all blends exhibit an abrupt increase in conductivity. However, analysis of small-angle X-ray scattering data indicates significant structure even in the disordered state for several blend compositions. By comparing the nature and structure of the disordered states with their corresponding ordered states, we find that this increase in conductivity through the order–disorder transition is most likely due to the elimination of grain boundaries. In either disordered or ordered states, the conductivity decreases as the total amount of homopolymer is increased, an unanticipated observation. This trend with increasing homopolymer loading is hypothesized to result from an increased density of “dead ends” in the conducting channel due to poor continuity across grain boundaries in the ordered state and the formation of concave interfaces in the disordered state. The results demonstrate that disordered, microphase-separated morphologies provide better transport properties than compositionally equivalent polycrystalline systems with long-range order, an important criterion when optimizing the design of polymer electrolytes.

Poly(vinyl alcohol)/SWNT Composite Film (2003)

Poly(vinyl alcohol) (PVA) composite films using poly(vinyl pyrrolidone) (PVP) and sodium dodecyl sulfate (SDS)-covered, well dispersed single wall carbon nanotubes (SWNT) exhibit significant improvement in tensile strength and modulus as compared to the control PVA and PVA/PVP/SDS films. The evidence of load transfer to the nanotubes in the composite film has been obtained from the shift in the Raman SWNT D* band peak position.
Tropomyosins in mosquito and house dust mite cross‐react at the humoral and cellular level (2018)

Tropomyosins from D. pteronyssinus and A. aegypti show humoral and cellular cross-reactivity, involving 5 potential T cell-activating regions. The more pronounced cross-reactivity of Aed a 10.01 and Der p 10 matched the higher sequence similarity of both proteins.
The body of the espresso coffee: the elusive importance. (2005)

The present study reports on the physico-chemical properties of espresso coffee, which may be relevant in the mouthfeel perception. In particular, total solids (concentration), density, rheological and interfacial properties have been determined as a function of cup volume and temperature. The correlation between physico-chemical properties and sensory properties have been described in the framework of oral processing problems.
Competitive Inhibition of Heparinase by Persulfonated Glycosaminoglycans: A Tool to Detect Heparin Contamination (2011)

Heparin and the low molecular weight heparins are extensively used as medicinal products to prevent and treat the formation of venous and arterial thrombi. In early 2008, administration of some heparin lots was associated with the advent of severe adverse effects, indicative of an anaphylactoid-like response. Application of orthogonal analytical tools enabled detection and identification of the contaminant as oversulfated chondroitin sulfate (OSCS) was reported in our earlier report. Herein, we investigate whether enzymatic depolymerization using the bacterially derived heparinases, given the structural understanding of their substrate specificity, can be used to identify the presence of OSCS in heparin. We also extend this analysis to examine the effect of other persulfonated glycosaminoglycans (GAGs) on the action of the heparinases. We find that all persulfonated GAGs examined were effective inhibitors of heparinase I, with IC(50) values ranging from approximately 0.5-2 μg/mL. Finally, using this biochemical understanding, we develop a rapid, simple assay to assess the purity of heparin using heparinase digestion followed by size-exclusion HPLC analysis to identify and quantify digestion products. In the context of the assay, we demonstrate that less than 0.1% (w/w) of OSCS (and other persulfonated polysaccharides) can routinely be detected in heparin.
Data from Inhibition of the Phosphatidylinositol 3-Kinase/Akt Pathway by Inositol Pentakisphosphate Results in Antiangiogenic and Antitumor Effects (2023)

&lt;div&gt;Abstract&lt;p&gt;The purpose of this study was to investigate the antiangiogenic and &lt;i&gt;in vivo&lt;/i&gt; properties of the recently identified phosphatidylinositol 3-kinase (PI3K)/Akt inhibitor Inositol(1,3,4,5,6) pentakisphosphate [Ins(1,3,4,5,6)P&lt;sub&gt;5&lt;/sub&gt;]. Because activation of the PI3K/Akt pathway is a crucial step in some of the events leading to angiogenesis, the effect of Ins(1,3,4,5,6)P&lt;sub&gt;5&lt;/sub&gt; on basic fibroblast growth factor (FGF-2)–induced Akt phosphorylation, cell survival, motility, and tubulogenesis &lt;i&gt;in vitro&lt;/i&gt; was tested in human umbilical vein endothelial cells (HUVEC). The effect of Ins(1,3,4,5,6)P&lt;sub&gt;5&lt;/sub&gt; on FGF-2-induced angiogenesis &lt;i&gt;in vivo&lt;/i&gt; was evaluated using s.c. implanted Matrigel in mice. In addition, the effect of Ins(1,3,4,5,6)P&lt;sub&gt;5&lt;/sub&gt; on growth of ovarian carcinoma SKOV-3 xenograft was tested. Here, we show that FGF-2 induces Akt phosphorylation in HUVEC resulting in antiapoptotic effect in serum-deprived cells and increase in cellular motility. Ins(1,3,4,5,6)P&lt;sub&gt;5&lt;/sub&gt; blocks FGF-2-mediated Akt phosphorylation and inhibits both survival and migration in HUVEC. Moreover, Ins(1,3,4,5,6)P&lt;sub&gt;5&lt;/sub&gt; inhibits the FGF-2-mediated capillary tube formation of HUVEC plated on Matrigel and the FGF-2-induced angiogenic reaction in BALB/c mice. Finally, Ins(1,3,4,5,6)P&lt;sub&gt;5&lt;/sub&gt; blocks the s.c. growth of SKOV-3 xenografted in nude mice to the same extent than cisplatin and it completely inhibits Akt phosphorylation &lt;i&gt;in vivo&lt;/i&gt;. These data definitively identify the Akt inhibitor Ins(1,3,4,5,6)P&lt;sub&gt;5&lt;/sub&gt; as a specific antiangiogenic and antitumor factor. Inappropriate activation of the PI3K/Akt pathway has been linked to the development of several diseases, including cancer, making this pathway an attractive target for therapeutic strategies. In this respect, Ins(1,3,4,5,6)P&lt;sub&gt;5&lt;/sub&gt;, a water-soluble, natural compound with specific proapoptotic and antiangiogenic properties, might result in successful anticancer therapeutic strategies.&lt;/p&gt;&lt;/div&gt;
Preparation of C-Axis-Oriented PLT Thin Films by the Metalorganic Chemical Vapor Deposition Method (1990)

La-modified lead titanate (PLT) thin films are prepared by the metalorganic chemical vapor deposition method. Tetraethyl lead, titanium tetraisopropoxide and trisdipivaloylmethanato lanthanum are used as source materials. The films obtained at 600°C under reduced pressure of 6 Torr constitute PLT of the single perovskite phase, and highly c -axis-oriented films are grown on MgO(100). The crystal structures are transferred from the tetragonal to the cubic structure with increasing molar fraction of La 2 O 3 . The dielectric constant and tan δ are around 800 to 2700 and 0.04 to 0.1.

To calculate the over-voltages and predict the probability of a BF, an accurate model of the tower and its grounding system is needed in electromagnetic transient (EMT) type simulators. There are a number of theoretical models for the equivalent circuit of a transmission tower. However, they either are not accurate enough or they are derived for a certain type of transmission tower, which limits their applicability. Numerical electromagnetic analyses have less simplifications compared to the theoretical solutions and are by far less expensive than field measurements. They also have the flexibility to analyze any type of tower. In this paper, the direct method for the measurement of tower impedance is implemented by NEC4 and applied to a 400-kV double circuit tower with all its details. Th e process of obtaining the wire network of the tower used in this paper is completely automated and it can be applied to any other type of transmission tower. Th e results of the numerical simulations are compared to those obtained with existing tower models. Th e developed model in this paper is capable of considering all the details of the tower and including the finite resistance of the ground and grounding electrodes.&lt;/div&gt;
The Synergistic Roles of Cholecystokinin B and Dopamine D5 Receptors on the Regulation of Renal Sodium Excretion (2016)

Renal dopamine D1-like receptors (D1R and D5R) and the gastrin receptor (CCKBR) are involved in the maintenance of sodium homeostasis. The D1R has been found to interact synergistically with CCKBR in renal proximal tubule (RPT) cells to promote natriuresis and diuresis. D5R, which has a higher affinity for dopamine than D1R, has some constitutive activity. Hence, we sought to investigate the interaction between D5R and CCKBR in the regulation of renal sodium excretion. In present study, we found D5R and CCKBR increase each other's expression in a concentration- and time-dependent manner in the HK-2 cell, the specificity of which was verified in HEK293 cells heterologously expressing both human D5R and CCKBR and in RPT cells from a male normotensive human. The specificity of D5R in the D5R and CCKBR interaction was verified further using a selective D5R antagonist, LE-PM436. Also, D5R and CCKBR colocalize and co-immunoprecipitate in BALB/c mouse RPTs and human RPT cells. CCKBR protein expression in plasma membrane-enriched fractions of renal cortex (PMFs) is greater in D5R-/- mice than D5R+/+ littermates and D5R protein expression in PMFs is also greater in CCKBR-/- mice than CCKBR+/+ littermates. High salt diet, relative to normal salt diet, increased the expression of CCKBR and D5R proteins in PMFs. Disruption of CCKBR in mice caused hypertension and decreased sodium excretion. The natriuresis in salt-loaded BALB/c mice was decreased by YF476, a CCKBR antagonist and Sch23390, a D1R/D5R antagonist. Furthermore, the natriuresis caused by gastrin was blocked by Sch23390 while the natriuresis caused by fenoldopam, a D1R/D5R agonist, was blocked by YF476. Taken together, our findings indicate that CCKBR and D5R synergistically interact in the kidney, which may contribute to the maintenance of normal sodium balance following an increase in sodium intake.
Multi-longitudinal-mode two-dimensional analysis of self-sustained pulsating laser diodes (2002)

Conformational flexibility of the 3' acceptor end of transfer ribonucleic acid (1980)

The intimate details of the conformational features and dynamics of the trinucleoside diphosphates CpCpA and ApCpC in aqueous solution have been arrived at by the complete analysis of their proton magnetic resonance spectra. In addition to the right-handed stacked species in which the phosphodiester torsions conform to the gauche-gauche domains, sugar puckers 3E, C4'-C5 approximately equal to 60 degrees, C5'-O5' approximately 180 degrees, C3'-O3' approximately equal to 205 degrees, and chi CN approximately equal to 40 degrees, the trimers display a variety of spatial configurations, an important one being a bulged configuration in which the central nucleotide unit is bulged out, enabling stacking interactions between the end units. It is further shown that the 3' acceptor end of tRNA, CpCpA, displays considerable flexibility for the terminal adenine nucleotide unit. Theoretical NMR calculations demonstrate that the predominant solution conformation does not conform to the CCA terminus of tRNA as reported by four independent crystallographic studies of tRNAPhe. It is shown that the preferred intramolecular order of CCA in solution is such that chi 1 = chi 2 = chi 3 = 40 degrees, all the three sugars are in 3E, psi 1 = psi 2 = psi 3 = 60 degrees, phi 2 and phi 3 = 170 and 180 degrees, respectively, phi 1 = phi 2' = 205 degrees, and omega 1/omega 1 and omega 2/omega 2' = 240/205 degrees and 295/265 degrees, respectively.
Growth, strain relaxation properties and high-κ dielectric integration of mixed-anion GaAs1-ySby metamorphic materials (2014)

Mixed-anion, GaAs1-ySby metamorphic materials with a wide range of antimony (Sb) compositions extending from 15% to 62%, were grown by solid source molecular beam epitaxy (MBE) on GaAs substrates. The impact of different growth parameters on the Sb composition in GaAs1-ySby materials was systemically investigated. The Sb composition was well-controlled by carefully optimizing the As/Ga ratio, the Sb/Ga ratio, and the substrate temperature during the MBE growth process. High-resolution x-ray diffraction demonstrated a quasi-complete strain relaxation within each composition of GaAs1-ySby. Atomic force microscopy exhibited smooth surface morphologies across the wide range of Sb compositions in the GaAs1-ySby structures. Selected high-κ dielectric materials, Al2O3, HfO2, and Ta2O5 were deposited using atomic layer deposition on the GaAs0.38Sb0.62 material, and their respective band alignment properties were investigated by x-ray photoelectron spectroscopy (XPS). Detailed XPS analysis revealed a valence band offset of &amp;gt;2 eV for all three dielectric materials on GaAs0.38Sb0.62, indicating the potential of utilizing these dielectrics on GaAs0.38Sb0.62 for p-type metal-oxide-semiconductor (MOS) applications. Moreover, both Al2O3 and HfO2 showed a conduction band offset of &amp;gt;2 eV on GaAs0.38Sb0.62, suggesting these two dielectrics can also be used for n-type MOS applications. The well-controlled Sb composition in several GaAs1-ySby material systems and the detailed band alignment analysis of multiple high-κ dielectric materials on a fixed Sb composition, GaAs0.38Sb0.62, provides a pathway to utilize GaAs1-ySby materials in future microelectronic and optoelectronic applications.

Optical performance of in‐plane electrophoretic color e‐paper (2009)

Abstract— Several e‐paper technologies are currently under development with the ultimate goal of replacing printed ink on paper. Here, optical performance measurements on monochrome in‐plane electrophoretic e‐paper devices with unsurpassed brightness, contrast, and viewing‐angle performance are reported. The measurement results are captured in a straightforward optical model that allows extrapolation to full‐color performance. It demonstrates that in‐plane electrophoretic color e‐paper technology has the unique potential to deliver on the high standards required by digital‐signage applications.
Race and education: Hidden links between media and Indigenous academic self-concept (2012)

The aim of this paper is to locate ideological constructions of racism in relation to the Australian education system that are imbricated within the structure of newspaper reporting. The study focuses on reports concerning the poor and rapidly declining Aboriginal student academic standards as presented in The Australian and the resultant socio-psychological implications held and enforced by, firstly, Australian society, and then, more significantly, adopted by the students themselves. The analysis of these reports follows the analytic paradigm of Critical Discourse Analysis (CDA) and is undertaken in two stages. Firstly, giving a general depiction of media techniques and structures, which highlight discursive practices of ‘othering’ of ethnic minority, and secondly, the effects of these stereotypes upon indigenous students’ academic self-concept.
Optical breakdown versus filamentation in fused silica by use of femtosecond infrared laser pulses (2003)

The competition between optical breakdown (OB) and laser-pulse filamentation (FL) in bulk fused silica is investigated by using a 1-kHz femtosecond infrared laser. We measure input powers corresponding to the threshold of OB and FL in terms of external focusing conditions. The results demonstrate that OB precedes FL for tight focusing, whereas for sufficiently long focal lengths FL takes places at a lower power than OB does.

Comparison of BRYAN Cervical Disc Arthroplasty With Anterior Cervical Decompression and Fusion (2009)

Two-year follow-up results indicate that cervical disc arthroplasty is a viable alternative to anterior cervical discectomy and fusion in patients with persistently symptomatic, single-level cervical disc disease.
One-dimensional implosions under gravity-induced hydrostatic pressure (1987)

An imploding cavity in a fluid-filled borehole is potentially attractive as a powerful source of acoustic energy for borehole seismic experiments. It is reasonable to model the fluid pressure response due to the implosion as purely one-dimensional. A simple analysis based on the assumption that the fluid behaves elastically, with a linear pressure/strain relation, predicts that the fluid pressure response becomes negative at depths less than that of the source. This is an untenable prediction since a fluid cavitates under negative pressure. It is more realistic to assume that the fluid behaves in a linear elastic fashion for negative strains (and positive pressures), and that the fluid pressure is zero for positive strains. This leads to a nonlinear, free-boundary problem in acoustic wave propagation, which surprisingly has a closed-form analytical solution. The analysis predicts the existence of several unexpected phenomena which could complicate the interpretation of data taken in borehole seismic experiments utilizing this type of source.
