A Novel Family of Boron‐Containing Hole‐Blocking Amorphous Molecular Materials for Blue‐ and Blue–Violet‐Emitting Organic Electroluminescent Devices (2002)

Abstract A novel family of amorphous molecular materials that function as hole blockers in organic electroluminescent (EL) devices, tris(2,3,5,6‐tetramethylphenyl)borane (TPhB), tris(2,3,5,6‐tetramethylbiphenyl‐4‐yl)borane (TBPhB), tris(2,3,5,6‐tetramethyl‐1,1′;4′,1″‐terphenyl‐4‐yl)borane (TTPhB), and tris[4‐(1,1′;3′,1″‐terphenyl‐5′‐yl)‐2,3,5,6‐tetramethylphenyl]borane (TTPhPhB), have been designed and synthesized. They readily form stable amorphous glasses with high glass‐transition temperatures, and are characterized by reversible cathodic reduction and relatively large HOMO–LUMO energy gaps. High‐performance blue‐ and blue–violet‐emitting organic EL devices have been developed using TBPhB, TTPhB, and TTPhPhB as hole blockers and N , N ′‐di(1‐naphthyl)‐ N , N ′‐diphenyl[1,1′‐biphenyl]‐4,4′‐diamine, tri( p ‐terphenyl‐4‐yl)amine, and N , N ′‐bis(3‐methylphenyl)‐ N , N ′‐diphenyl‐[1,1′‐biphenyl]‐4,4′‐diamine as emitters.

Automated and cost effective maintenance tools (2002)

Continuous real-time monitoring of batteries has been advocated for improved reliability of standby power plant. However, existing commercial monitoring systems often fail to meet user expectations and are therefore difficult to justify for wide-scale implementation. A model which accommodates user-based ideas about the functions of battery and power system monitoring is described. The development of a low cost, "universal" battery and power monitoring system suitable for implementation across Telstra's network is also reported.
Supporting Bulk Data Transfers of High-End Applications with Guaranteed Completion Time (2007)

In high-end grid networks, distributed resources (scientific instruments, CPUs, storages, etc.) are interconnected to support computing-intensive and data-intensive applications, which often require reliable and efficient transfer of gigabits or even terabits of data among endpoints. To facilitate the efficient scheduling of endpoint resources, networks should provide a service which guarantees that a specified amount of data is transferred within a strict time window. Existing "FixRate-FixTime" resource reservation architectures such as IntServ/RSVP reserve for each flow a constant amount of resource from a specified starting time. Instead, a bulk data transfer can start at any time after its arrival, use any and even time variant bandwidth value, as long as it is completed before its deadline. This paper proposes a flexible "Multi-Interval" resource reservation approach, which divides the active window of a transfer into multiple sub-intervals, and reserves constant amount of resource in each of them. We identify a possible evolution path towards the proposed architecture, and use simulations to demonstrate the potential performance gain from increasing flexibility.
Fings ain’t wot they used to be (1996)

Change is a constant of organizational life today, so we are told. Yet few, if any, writers on the subject define what they mean by change. It is assumed that all change is the same. Sets out to correct this omission in the literature by describing first two, and then three, types of change with the aim of clarifying what managers and other professionals concerned with this subject need to take into account when planning a change intervention. Without proper understanding of the type of change that is being planned, poor diagnosis and inadequate formulation and implementation will result. Finally, implications for organizations are spelt out and a distinction between changes and transitions is made, which, it is hoped, will enable managers to understand some of the frustrations about change when things do not go as planned.
Copolymers of Hydroxyethyl Methacrylate with Quadrol Methacrylate and with Various Aminoalkyl Methacrylamides as Fibroblast Cell Substrata (1990)

Universal application of hydrophilic hydrogels like poly(hydroxy ethyl methacrylate) [p(HEMA)], as biomaterials is limited due to their inabil ity to favorably affect eukaryotic cell growth. In an attempt to favorably manipulate surface properties, a series of HEMA copolymers was made with 10-40% aminoethyl methacrylamide (AEMA), aminopropyl methacrylamide (APMA), Quadrol methacrylate (QM), N,N'-bis(2-hydroxypropyl)aminoethyl meth acrylamide (HPAEMA) or dimethylaminoethyl methacrylate (DMAEMA). Balb/c 3T3 fibroblast cell growth was observed on HEMA:AEMA (80:20), HEMA:QM (80:20) and HEMA:HPAEMA (90:10) copolymers. Cell growth on HEMA: AEMA (80:20) was comparable to HEMA:DMAEMA (60:40). HEMA copolymers containing APMA, a homolog of AEMA, exhibited cytotoxicity. Cationic groups of primary and tertiary amines present in the HEMA copoly mer hydrogels favorably contribute to the support of cell growth. The effect of hydroxyl groups on cell growth appears to be favorable. The extent of cell growth varied with the concentration of the cationic groups in the hydrogel. The cytotoxicity of the HEMA:APMA copolymers as compared with the bio compatibility of the HEMA:AEMA copolymers suggests that the length of the branch from the polymer chain for copolymers with primary amino groups may be a critical factor in biocompatibility.
Deadlock problems in a multidatabase environment (2002)

A deadlock detection algorithm and a deadlock prevention algorithm in a multidatabase environment are introduced. The deadlock detection algorithm is based on the potential conflict graph (PCG) introduced by Y. Breitbart et al. (1990). The deadlock prevention algorithm is based on the value data protocol discussed. The correctness of both algorithms is proved, and their performance is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Quality Evaluation and Automatic Classification in Resistance Spot Welding by Analyzing the Weld Image on Metal Bands by Computer Vision (2015)

This paper introduces a novel method for the quality evaluation of resistance spot welds. The evaluation is based on computer vision methods, which allow nondestructive on-line real-time processing. The input of the system is the image of a weld imprint on a metal band which covers the electrodes against wear and soiling. In order to find the position of the resistance spot welds, we describe an image registration method based on geometric pattern matching for alignment system in metal parts. Further we extract features describing the shape of localized objects in segmented images .Using these shape descriptors (geometric feature) we classify the defects by Artificial Neural Network.
Cytoprotection by glycine against ATP-depletion-induced injury is mediated by glycine receptor in renal cells (2005)

It is known that glycine protects mammalian cells against ischaemic cell injury by preventing cellular membrane leakage. However, the molecular mechanisms have not yet been clearly elucidated. The purpose of the present study was to clarify whether GlyR (glycine receptor) acts as a key mediator in cytoprotection of glycine. cDNA encoding human GlyRa1 (a1-subunit of glycine receptor) was transfected into HEK-293 cells. The membrane integrity of the cells with or without GlyRa1 was examined by the uptake of marker compounds, the release of LDH (lactate dehydrogenase) and the exclusion of Trypan Blue. Glycine prevented the permeability of 70 kDa dextrans and 140 kDa LDH in the cells in which GlyR was expressed under conditions of ATP depletion. The inhibition of endogenous GlyR expression by RNA interference attenuated the cytoprotection by glycine. Furthermore, the mutation of Tyr202 to phenylalanine in GlyRa1 blocked the glycine-mediated cytoprotection, while the mutation of Tyr202 to leucine abolished the cytoprotection by strychnine. Our results suggested that the cytoprotection of glycine against ATP-depletion-induced injury might be mediated by GlyR.
Neuroblastoma: a clinical challenge and biologic puzzle (1995)

Neuroblastoma is the third most common malignancy in childhood and accounts for at least 15 percent of cancer-related deaths in children. The varied clinical behavior of this disease, ranging from spontaneous regression in some to progression while under aggressive therapy in others, has been associated with various biologic differences, providing insight into pathophysiology and possibilities for more specific treatments. This article reviews the epidemiology, pathophysiology, clinical evaluation, and treatment of neuroblastoma.
Injectable cell/hydrogel microspheres induce the formation of fat lobule-like microtissues and vascularized adipose tissue regeneration (2012)

In this paper, we demonstrated that collagen/alginate microspheres could be generated by a non-contact microfabrication device and serve as excellent cell embedding and delivery devices as they were porous, injectable and able to provide growth- and differentiation-supporting matrix for human adipose-derived stem cells (hASCs). The microsphere matrix demonstrated highly porous structure and mechanical stability for as long as 90 days. hASCs demonstrated high viability after microsphere formation as well as higher proliferation and more mature adipocytes induction compared to two-dimensional culture. After four weeks culture in adipogenic differentiation medium, adipocytes/collagen/alginate microspheres highly mimicking natural fat lobules were obtained and injected subcutaneously into the head of node mice. The in vivo study demonstrated vascularized adipose tissue formation in four weeks. The regenerated vasculature among the transplantation showed functional anastomosis with host vasculature, suggesting that these cell/hydrogel microspheres present injectable adipocytes delivery devices capable of generating vascularized adipose tissue in vivo and thus suitable for cell transplantation and tissue regeneration.
The <i>Bacillus subtilis crh</i> gene encodes a HPr-like protein involved in carbon catabolite repression (1997)

Carbon catabolite repression (CCR) of several Bacillus subtilis catabolic genes is mediated by ATP-dependent phosphorylation of histidine-containing protein (HPr), a phosphocarrier protein of the phosphoenolpyruvate (PEP): sugar phosphotransferase system. In this study, we report the discovery of a new B. subtilis gene encoding a HPr-like protein, Crh (for catabolite repression HPr), composed of 85 amino acids. Crh exhibits 45% sequence identity with HPr, but the active site His-15 of HPr is replaced with a glutamine in Crh. Crh is therefore not phosphorylated by PEP and enzyme I, but is phosphorylated by ATP and the HPr kinase in the presence of fructose-1,6-bisphosphate. We determined Ser-46 as the site of phosphorylation in Crh by carrying out mass spectrometry with peptides obtained by tryptic digestion or CNBr cleavage. In a B. subtilis ptsH1 mutant strain, synthesis of beta-xylosidase, inositol dehydrogenase, and levanase was only partially relieved from CCR. Additional disruption of the crh gene caused almost complete relief from CCR. In a ptsH1 crh1 mutant, producing HPr and Crh in which Ser-46 is replaced with a nonphosphorylatable alanyl residue, expression of beta-xylosidase was also completely relieved from glucose repression. These results suggest that CCR of certain catabolic operons requires, in addition to CcpA, ATP-dependent phosphorylation of Crh, and HPr at Ser-46.
DETECTION OF INCIPIENT AND LOW CURRENT FAULTS IN ELECTRIC DISTRIBUTION SYSTEMS (1989)

Many faults in electric distribution systemsmot draw enough current to be detected by conventional overcurrent protective devices. Researchers at Texas A&M University have been investigating incipient and low current faults for many years and have developed detection techniques using advanced concepts in signal processing and pattern recognition. This paper reviews the research at Texas A&M in incipient fault detection and describes the digital and analytical techniques used to discriminate faults from normal system activity. The results of staged fault tests are reviewed and detection approaches are presented. The application of these techniques to spacebome power systems is made with specific examples. Conclusions are drawn as to the appropriateness of these approaches to spacebome power system fault detection.
An annotated catalogue of salivary gland transcripts in the adult female mosquito, Ædes ægypti* (2007)

Overall, this paper contributes to the novel identification of 573 new transcripts, or near 3% of the AE. aegypti proteome assuming a 20,000-protein set, and to the best-described sialome of any blood-feeding insect.
Plasma N‐terminal pro‐brain natriuretic peptide in Type 1 diabetic patients with and without diabetic nephropathy (2003)

This is the first demonstration that NT proBNP levels are significantly higher in Type 1 diabetic patients with albuminuria. This may be caused by a down-regulation of A-type guanylate cyclase-coupled natriuretic peptide receptors in renal tubules or by elevated NT proBNP levels leading to higher glomerular hydraulic pressure or higher capillary permeability and possibly increased albumin excretion. Further studies are required to investigate the potential role of NT proBNP in patients with diabetic nephropathy and such other co-morbidities as cardiovascular disease.
Imaging laser irradiated enamel surfaces with polarization sensitive optical coherence tomography (2008)

Several studies have shown that lasers can be used to modify the surface morphology and chemical composition of tooth enamel to render it less soluble. Other studies have shown that Polarization Sensitive Optical Coherence Tomography (PS-OCT) can be used to non-destructively measure the efficacy of fluoride in inhibiting the development of artificial caries lesions. The purpose of this study was to determine if PS-OCT can be used to measure inhibition of enamel demineralization after CO(2) laser irradiation. Polarized light microscopy and microradiography were used to measure lesion severity on histological thin sections for comparison. PS-OCT was able to measure a significant reduction in the integrated reflectivity due to inhibition by the laser even though the laser modification of the enamel surface caused a slight increase in reflectivity. This study shows that the PS-OCT is well-suited for in vivo measurements of caries inhibition after laser treatments.
Anti-inflammatory and antioxidant activities of Moringa peregrina Seeds (2011)

The present study was carried out to evaluate the anti-inflammatory and antioxidant activities of Moringa peregrina seeds ethanolic and aqueous extracts. The anti-inflammatory effect Moringa peregrina extracts was examined in rats, using fresh egg albumin-induced oedema, and diclofenac (100 mg/kg) was used as reference drug for comparison. The methods selected to design a convenient system to assess the antioxidant activity of Moringa peregrina extracts including, reducing power, chelating activity on Fe2+, free radical-scavenging, total antioxidant, superoxide radical scavenging, hydrogen peroxide scavenging and hydroxyl radical scavenging activities in an attempt to understand its mechanism of action, which may pave the way for possible therapeutic applications. In addition, the results were compared with natural and synthetic antioxidants, such as α- tocopherol, ascorbic acid, butylated hydroxytoluene(BHT), butylated hydroxyanisole (BHA) and trolox. The results indicated that Moringa peregrina ethanolic and aqueous extracts (100-300 mg/kg p. o.) also dose-dependently and significantly inhibited (p < 0.05-0.001) fresh egg albumin-induced acute inflammation. Ethanolic and aqueous extracts of Moringa peregrina exhibited a strong reducing power, Fe2+ chelating effect, free radical scavenging activity, hydrogen peroxide scavenging ability, and hydroxyl radical scavenging activity. Antioxidant activity of the ethanolic and aqueous extracts increased with increased concentrations in the range of 20-140μg/ ml the extracts also exhibited a strong superoxide radical scavenging activity. This study showed that Moringa peregrina extracts exhibited antioxidant activity in all tests and the extracts could be considered as a source of natural antioxidants. Taken together, Moringa peregrina has potential as an anti-inflammatory and antioxidant agent against inflammation and free radicals and deserves clinical trial in the near future.
Scanning Auger investigation of commercial multifilamentary Nb&lt;inf&gt;3&lt;/inf&gt;Sn conductors (1983)

A Physical Electronics 595 Scanning Auger Microprobe was used to study etched filaments and transverse sections of variously reacted commercial bronze matrix multifilamentary Nb <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> Sn conductors. Using beams as fine as 100 nm, tin concentration profiles were observed in polished samples. Differences were noted in the shape of the tin gradient as a function of the location of the reacted filaments within the wires. The tin content of the bronze was also measured between pre-reacted filaments in an unreacted composite and found to be about 1 at.% lower than in the large bronze reservoirs. In a Harwell composite with P-poisoned niobium diffusion barriers, P was detectable in the Nb <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> Sn formed on the barrier but not on the filaments.
<title>Development and standardization of a spectral characteristics database for evaluating color reproduction in image input devices</title> (1998)

We are developing a spectral characteristics database for evaluating color reproduction in image input devices. The database is designed so that spectral characteristics are systematically divided by category, according to the purpose to which they are to be applied, and every category has a sufficient variety of samples. The categories are as follows: photographic materials, graphic color printing, computer color printers output, paints, flowers, leaves, human skin colors and historical Krinov data. The total number of colors is 49,672. The database is being proposed to be published as Japanese/International standard technical reports for use in establishing a new color reproduction evaluation method.
Intra-channel Reconfigurable Interface for TSV and Micro Bump Fault Tolerance in 3-D RAMs (2014)

Three-dimensional (3-D) integration using through-silicon-via (TSV) is an emerging technology for integrated circuit (IC) design. It has been used in DRAM die stacking extensively. However, yield remains a key issue for volume production of 3-D RAMs. In this paper, we present a point-to-point interconnection structure derived from bus and propose a fault tolerance interface scheme for TSVs and micro bumps to enhance their manufacturing yield in the 3-D RAMs. The interconnection structure is inherently redundant and thus can replace defective TSVs or micro bumps without using repair circuits. Global and local reconfiguration approaches are proposed which benefit distinct situations of the 3-D RAM. Analyses show that the proposed intra-channel reconfigurable interconnection scheme can improve the yield of the 3-D RAM effectively. Compared to the previous solution using an inter-channel reconfigurable interconnection scheme, the yield improvement can be as large as 23% which is very significant.
GPR imaging of dual-porosity rocks: Insights to fluid flow (2008)

Dual-porosity rocks, such as those that are fractured and/or karstic, are highly heterogeneous and present a great challenge to predicting fluid-flow properties.
Evidence for an intercellular covalent reaction essential in antigen-specific T cell activation. (1989)

The inductive interaction between class II+ APC and Th cell was investigated in a human system at the chemical level. The study set out to test the predictions of a model of Ag presentation in which epsilon-amino groups and carbonyl groups at the surface of APC and T cell react covalently to form reversible intercellular Schiff bases. In the experimental system of oxidative mitogenesis this process results in T cell activation. If oxidative mitogenesis is an experimental amplification of a physiologic process, and intercellular Schiff base formation is essential in Ag presentation, then it should be possible to inhibit Ag presentation by prior formation of Schiff bases on the surface of participating cells. In this situation Ag-induced T cell activation and T cell activation induced by periodate oxidation should invariably behave in the same way. It should also be possible to demonstrate Schiff base formation occurring between accessory cells and lymphocytes directly and definitively by means of specific reduction with sodium cyanoborohydride. Aldehyde treatment of accessory cells should prevent this intercellular Schiff base formation. In this study the following observations were made. 1) Both Ag-specific and periodate-induced T cell activation were inhibited by aldehyde treatment of class II+ accessory cells. 2) Noncross-linking donors of carbonyl groups other than aldehydes inhibited Ag-specific T cell activation. 3) Brief, low-dose treatment of T cells with aldehydes inhibited Ag-dependent T-cell activation. 4) Exogenous amino groups in the form of lysine and other amino acids inhibited both Ag-specific and periodate-induced T-cell activation. 5) The weak reducing agent sodium cyanoborohydride which is specific for Schiff bases at neutral pH inhibited both Ag-induced and periodate-induced T cell activation. Responses to PHA were markedly prolonged by this reagent. 6) Schiff base formation occurring between accessory cells and lymphocytes was detected directly and definitively by means of radiolabeling with NaCNB(3H)3 at neutral pH. These data are consistent with the view that the formation of reversible covalent Schiff bases between ligands on APC and T cell is an essential process in Ag-induced T cell activation.
