Bridge Displacement Monitoring Method Based on Laser Projection-Sensing Technology (2015)

Bridge displacement is the most basic evaluation index of the health status of a bridge structure. The existing measurement methods for bridge displacement basically fail to realize long-term and real-time dynamic monitoring of bridge structures, because of the low degree of automation and the insufficient precision, causing bottlenecks and restriction. To solve this problem, we proposed a bridge displacement monitoring system based on laser projection-sensing technology. First, the laser spot recognition method was studied. Second, the software for the displacement monitoring system was developed. Finally, a series of experiments using this system were conducted, and the results show that such a system has high measurement accuracy and speed. We aim to develop a low-cost, high-accuracy and long-term monitoring method for bridge displacement based on these preliminary efforts.
Fabrication of highly concentrated Er3+ doped aluminosilicate films via sol-gel processing (1995)

Optically active highly concentrated Er3+–Al3+ codoped silica thin films were fabricated on fused silica substrates by sol-gel method. The synthesis of the Er3+–Al3+ double alkoxide was intended to prevent the optically harmful Er clustering by the selective coordination of Al3+ around Er3+ ions. The molar Er ion concentration was varied from 3811 to 23719 ppm. Photoluminescence (PL) measurements indicated that Er ions were optically active in all films of different Er concentrations. A broadband peak was observed at 1531 nm with the full width at half-maximum (FWHM) of 42 nm, which corresponds to the 4I13/2→4I15/2 transition. The shape, peak position, and FWHM of the PL signals from the sol-gel derived Er3+ doped silica were quite comparable to those prepared by other methods. The PL peak showed maximum intensity at an Er concentration of 8535 ppm. This implies the concentration quenching at higher Er concentrations.

Optical-conductivity spectra have been measured on the correlated electron system ${\mathrm{Sr}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{La}}_{\mathit{x}}$${\mathrm{TiO}}_{3}$ (0\ensuremath{\le}x\ensuremath{\le}1) in order to determine how the electronic structure depends on the filling of the 3d-electron conduction band. While metallic resistivity was observed in all samples with x\ensuremath{\ge}0.1, the optical-conductivity spectra have revealed a critical change in the electronic structure: The effective carrier mass, which has been deduced by analysis of the optical-conductivity spectra and the energy-loss function, is critically enhanced as the x=1 filling case (Ti 3${\mathit{d}}^{1}$ configuration) is approached, perhaps due to electron-correlation effects, in a manner reminiscent of the Mott-Hubbard transition.
Optimization of memory utilization for partially parallel QC-LDPC decoder (2010)

Quasi-cyclic (QC) low-density parity-check (LDPC) codes have advantages over other types of LDPC codes due to their cyclic shifting property. In this paper, a partially parallel QC-LDPC decoder with efficient memory design is proposed. To improve the memory utilization, the structures of efficient chunk and predictor are realized. The efficient chunk can store parts of check-to-variable messages. This design can effectively reduce the memory requirement. Furthermore, the predictor verifies variable-to-check messages and updates efficient chunks instantly. With less check-to-variable messages and variable-to-check messages stored in the memory, this decoding architecture only deposits few messages in several efficient chunks, such that the cost of memory is less. Eventually, the proposed approach dramatically reduces memory requirement about 65% compared to the traditional method while maintaining the same low-cost.
Assessment of Retinal Structure and Function in Ames Waltzer Mice (2003)

Although Pcdh15 is present in neural retina, its role remains unclear. Mutations in the Pcdh15 did not result in retinal abnormalities in the four alleles of Ames waltzer tested in this study. The explanation for the absence of retinal phenotype in the Ames mouse should be helpful in understanding USH1F and developing treatments for this disorder.

The results revealed that customer co-creation attitude has a positive and significant mediating role between factors and customer value co-creation behavior. The results of this study will open a new avenue in the tourism sector and as well for scholars and practitioners.
Stimulation of a membrane tyrosine phosphatase activity by somatostatin analogues in rat pancreatic acinar cells (1992)

A phosphoryl protein tyrosine phosphatase (PTPase) activity has been characterized in rat pancreatic acinar membranes using 32P-labeled poly(Glu,Tyr) as substrate. Acinar membranes exhibited a high affinity for the substrate, with an apparent Km of 0.46 microM and an apparent Vmax of 0.9 nmol.mg protein-1.min-1. Acinar membrane PTPase activity displayed specific characteristics of other PTPases; it was inhibited by the inhibitors Zn2+, orthovanadate and by the divalent cations Mn2+ and Mg2+, and was stimulated by the reducing-agent dithiothreitol. It was also inhibited by soybean trypsin inhibitor and stimulated by trypsin. Gel permeation of pancreatic acinar membranes gave a single peak of enzyme activity with an apparent molecular mass of 70 000 Da. Further purification by HPLC on DEAE revealed two peaks of PTPase activity at 120 mM and 180 mM NaCl. These two peaks reacted in a Western-blot procedure with anti-(peptide) serum directed towards conserved domain of PTPase as a common 67-kDa form associated with lower-molecular-mass proteolytic fragments (31-56 kDa). Incubation of pancreatic acini with somatostatin analogues, SMS 201-995 or BIM 23014, resulted in a stimulation of membrane PTPase activity. The stimulation was rapid and transient, with a maximal level reached within 15 min of addition. The two analogs stimulated PTPase activity in a dose-dependent manner with half-maximal activation occurring at 7 pM and 37 pM and maximal activation at 0.1 nM and 0.1-1 nM for SMS 201-995 and BIM 23014, respectively. The stimulated-membrane PTPase activity also eluted at an apparent molecular mass of 70 kDa in gel-permeation chromatography. The two analogs inhibited the binding of [125I-Tyr3]SMS 201-995 to pancreatic acinar membranes with similar relative potencies to that observed on stimulation of PTPase activity. We conclude that pancreatic acinar membranes possess a low-molecular-mass PTPase which is stimulated by somatostatin analogs at concentrations involving activation of membrane somatostatin receptors.

A complete timing generator has been realized using five beam-leaded silicon and two tantalum integrated circuits, including 217 transistors, 345 resistors, and capacitors totaling 400 pf, all mounted on one square inch of ceramic.
A comparison of the efficacy, adverse effects, and patient compliance of the sena-graph®syrup and castor oil regimens for bowel preparation. (2010)

Sena-Graph syrup has recently been formulated by an Iranian pharmaceutical company for being used in bowel evacuation before radiography, colonoscopy and surgery. This study compares the efficacy, adverse effects and patient compliance of two bowel preparation regimens with castor oil and Sena-Graph syrup in of outpatients for Intravenous Urography (IVU). One hundred and fourteen consecutive outpatients were randomized to receive either the standard bowel preparation with 60 mL of castor oil or the test method with 60 mL of Sena-Graph syrup before IVU examination. Demographic data of patients and their prior bowel preparation experience were collected before the examination. Two radiologists, blinded to the method of bowel preparation, reviewed the radiographs and graded the bowel preparation. The compliance and acceptability of both regimens were assessed by using structured questionnaires filled by the patients. The Numbers, ages, weights and gender distribution of patients and their prior bowel preparation experience in the two groups did not differ significantly. The cleanliness scores for the castor oil and Sena-Graph group were 3.97 ± 0.971 and 4.87 ± 0.917, respectively. The results indicated that Sena-Graph syrup causes a better bowel cleansing compared castor oil. Adverse effects in Sena-Graph groups were significantly lower than the castor oil group. Acceptability of the regimen in patients who used Sena-Graph was higher than the other group. The Sena-Graph regimen is significantly more effective and better tolerated than of Castor oil regimen in bowel cleansing. The incidence and severity of the adverse effects from Castor oil was higher than Sena-Graph.
Recursive restartability: turning the reboot sledgehammer into a scalpel (2005)

Even after decades of software engineering research, complex computer systems still fail, primarily due to nondeterministic bugs that are typically resolved by rebooting. Conceding that Heisenbugs will remain a fact of life, we propose a systematic investigation of restarts as "high availability medicine." In this paper we show how recursive restartability (RR) - the ability of a system to gracefully tolerate restarts at multiple levels improves fault tolerance, reduces time-to-repair and enables system designers to build flexible, highly available software infrastructures. Using several examples of widely deployed software systems, we identify properties that are required of RR systems and outline an agenda for turning the recursive restartability philosophy into a practical software structuring tool. Finally, we describe infrastructural support for RR systems, along with initial ideas on how to analyze and benchmark such systems.
The Efficient Production of Human Epidermal Growth Factor by <i>Bacillus brevis</i> (1996)

A system has been developed for the efficient production of heterologous proteins using Bacillus brevis as a host that secretes large amounts of cell wall protein into the medium. The promoter region and signal peptide-encoding region of the cell wall protein gene were used to construct an expression-secretion vector. Bacterial proteins such as amylases can be produced in large amounts by this system (1 g/l or more), but mammalian proteins such as human alpha-amylase are produced at a low level (one or two orders of magnitude less than for bacterial proteins). The highly efficient secretion of human epidermal growth factor (h-EGF, more than 1 g/l) was obtained with B. brevis HPD31 as the host and plasmid pHY481, derived from B. brevis 481, as the vector. Recombinant hEGF was purified easily from the culture supernatant by two steps. Purified hEGF had the identical NH2-terminal amino acid sequence and COOH-terminal amino acid sequence with those of the authentic hEGF, and it was fully active in biological assays. This recombinant hEGF has been shown to be successful for biological wool harvesting (CSIRO, Australia). These results, in combination with previous results, indicate that foreign proteins of diverse origins can be produced efficiently as functional proteins in B. brevis.
Towards Low Delay Sub-Stream Scheduling (2010)

Peer-to-Peer streaming is an effectual and promising way to distribute media content. In a mesh-based system, pull method is the conventional scheduling way. But pull method often suffers from long transmission delay. In this paper, we present a novel sub-stream-oriented low delay scheduling strategy under the push-pull hybrid framework. First the sub-stream scheduling problem is transformed into the matching problem of the weighted bipartite graph. Then we present a minimum delay, maximum matching algorithm. Not only the maximum matching is maintained, but also the transmission delay of each sub-stream is as low as possible. Simulation result shows that our method can greatly reduce the transmission delay.
The kinetics of the oxide charge trapping and breakdown in ultrathin silicon dioxide (1993)

The kinetics of carrier trapping and breakdown in oxides of less than 5 nm was studied. It was found that electron trapping was negligible, but hole trapping was relatively high. An effective oxide trap density due to tunnel annealing was proposed. The rate equation of carrier trapping in the bulk oxide was presented in connection with the generated hole injection by anode surface plasmons. The voltage variation during a constant current test was analyzed using the hole trapping model and capacitance-voltage measured interface trap generation, and approximate values for the capture cross section and hole generation rate were extracted. The gate voltage shift rebounded after 30–100 C/cm2 electron fluence due to interface trap generation. In ultrathin oxides hole trapping causes breakdown, and that trapping is mainly developed in localized weak areas. Using the weak area breakdown model we found that the ratio of weak to robust area is about 5%.
Boron Neutron Capture Therapy for Malignant Brain Tumors (2016)

Boron neutron capture therapy (BNCT) is a biochemically targeted radiotherapy based on the nuclear capture and fission reactions that occur when non-radioactive boron-10, which is a constituent of natural elemental boron, is irradiated with low energy thermal neutrons to yield high linear energy transfer alpha particles and recoiling lithium-7 nuclei. Therefore, BNCT enables the application of a high dose of particle radiation selectively to tumor cells in which boron-10 compound has been accumulated. We applied BNCT using nuclear reactors for 167 cases of malignant brain tumors, including recurrent malignant gliomas, newly diagnosed malignant gliomas, and recurrent high-grade meningiomas from January 2002 to May 2014. Here, we review the principle and history of BNCT. In addition, we introduce fluoride-18-labeled boronophenylalanine positron emission tomography and the clinical results of BNCT for the above-mentioned malignant brain tumors. Finally, we discuss the recent development of accelerators producing epithermal neutron beams. This development could provide an alternative to the current use of specially modified nuclear reactors as a neutron source, and could allow BNCT to be performed in a hospital setting.
Electron Paramagnetic Resonance Spectroscopy of the Heme Domain of Inducible Nitric Oxide Synthase:  Binding of Ligands at the Arginine Site Induces Changes in the Heme Ligation Geometry (1996)

The electron paramagnetic resonance spectra of the heme domain of inducible nitric oxide synthase (iNOS) demonstrate a close relationship to the corresponding spectra of the neuronal isoform (nNOS). The binding of ligands to the iNOS arginine site perturbs the environment of the high-spin ferriheme in a highly ligand-specific manner. The iNOS forms five-coordinate, high-spin complexes with arginine analogs which are clearly related to the corresponding complexes of nNOS. Studies indicate that the binding of L-arginine, N(omega)-hydroxy-L-arginine (NHA), and N(omega)-methyl-L-arginine (NMA) produces various spectroscopic species closely corresponding to the equivalent complexes of nNOS, while N(omega)-nitro-L-arginine (NNA) binding produces a state which appears intermediate in character between the nNOS NNA and arginine complexes. These spectroscopic studies have permitted the determination of ligand-specific high-spin states which reveal similarities and differences between iNOS and nNOS.
A methodology for yield-specific leakage estimation in memory (2014)

A simulation based pre-silicon leakage estimation methodology for SRAM is proposed. The methodology is easily extended to different voltage and temperature corners and it enables determination of leakage yield. It comprehends the impact of die to die and within die variations. It is used to generate yield specific leakage multipliers to capture impact of variability on leakage. Comparative studies between different bit cells show that relative leakage could be up to 53% different if we do not use the methodology. Finally, results from the methodology are shown to match measured silicon data at 22nm tri-gate CMOS technology within 12% accuracy over the region of interest.

The G11 Gene Located in the Major Histocompatibility Complex Encodes a Novel Nuclear Serine/Threonine Protein Kinase (1998)

Protein kinases are involved in signal transduction pathways and play fundamental roles in the regulation of cell functions. Here we report that the gene G11 located in the human major histocompatibility complex encodes a novel Ser/Thr protein kinase. The G11 gene products of 41.5 and 30 kDa were expressed in insect cells using the baculovirus system and transiently in the mammalian cell line COS-7. It was found that after immunoprecipitation of the G11 polypeptides from recombinant baculovirus-infected insect cell lysates or transfected COS-7 cell lysates the immunoprecipitates contained a Mn2+-dependent protein kinase activity that phosphorylated alpha-casein at Ser/Thr residues and histone at Ser residues. Furthermore, mutation of the ATP-binding site by converting the invariant lysine in the catalytic domain (amino acid 317) to a proline resulted in the complete ablation of the enzyme activity. This was consistent with the observation that the G11 polypeptide can be covalently modified by the reactive ATP analogue 5'-p-fluorosulfonylbenzoyladenosine in the absence of ATP, and that this modification is prevented in the presence of 1 mM ATP, indicating that the kinase domain of the G11 polypeptide is capable of binding ATP. Immunofluorescence staining of transfected COS-7 cells transiently expressing G11 revealed that this novel Ser/Thr protein kinase is localized predominantly in the nucleus.
Antiglobulins in Endocarditis (1972)

Twenty-five patients with endocarditis and serum antiglobulin activity were studied. The antiglobulins were detected by use of the latex agglutination reaction; only eight sera reacted with sensitized sheep cells and one with human O CD erythrocytes coated with anti-CD (Ripley) antibody. Absorption of the sera with the infecting organisms produced a decrease in antiglobulin activity in 10 of these sera. Absorption with other reference bacteria did not lower the titer of latex agglutination in 9 of 10 of these sera. No inhibition of antiglobulin activity by autologous immunoglobulin G was demonstrable. These findings suggest that some antiglobulins interact with the immunoglobulin G-bacterial complex and are analogous to anti-antibodies.
Ultrathin Pt-Based Alloy Nanowire Networks: Synthesized by CTAB Assistant Two-Phase Water−Chloroform Micelles (2009)

Ultrathin Pt-based PtM (M = Pd, Ru, Au, Fe) alloy nanowire networks could be facilely synthesized using a soft template formed by cetyltrimethylammonium bromide in a two-phase water−chloroform system. The as-synthesized Pt-based alloyed nanowires show the fcc crystal phase. They have an average diameter of ∼2.3 nm and form porous nanonetworks, which can be potentially used for a number of catalytic applications. It was found that PtRu alloy nanonetworks showed more efficient catalytic activity for the hydrogenation of azo bonds in methyl orange than that of PtPd, PtAu, and pure Pt.
Throughput of random access without message passing (2008)

We develop distributed scheduling schemes that are based on simple random access algorithms and that have no message passing. In spite of their simplicity, these schemes are shown to provide high throughput performance: they achieve the same performance as that of some maximal scheduling algorithms, e.g. Maximum Size scheduling algorithms.
The Making of a Forester: Field Experience for the Nineties (1987)

Foresters, when I was in college, were inclined to talk about 1980 as the future, but when I started teaching the magic year had become 2000. I am now startled to discover that the year 2030 is the year of destiny. I suppose long range planners such as Foresters are lucky in that almost no one involved in futurist activity is around to be embarrassed when some cynic realizes that the prediction fell flat. Perhaps my age will protect me as I set out to consider how the summer job of 1997 will differ from the Ag. 104 activities of 1987.
Bayesian Degradation Analysis With Inverse Gaussian Process Models Under Time-Varying Degradation Rates (2017)

Degradation observations of modern engineering systems, such as manufacturing systems, turbine engines, and high-speed trains, often demonstrate various patterns of time-varying degradation rates. General degradation process models are mainly introduced for constant degradation rates, which cannot be used for time-varying situations. Moreover, the issue of sparse degradation observations and the problem of evolving degradation observations both are practical challenges for the degradation analysis of modern engineering systems. In this paper, parametric inverse Gaussian process models are proposed to model degradation processes with constant, monotonic, and S-shaped degradation rates, where physical meaning of model parameters for time-varying degradation rates is highlighted. Random effects are incorporated into the degradation process models to model the unit-to-unit variability within product population. A general Bayesian framework is extended to deal with the degradation analysis of sparse degradation observations and evolving observations. An illustrative example derived from the reliability analysis of a heavy-duty machine tool's spindle system is presented, which is characterized as the degradation analysis of sparse degradation observations and evolving observations under time-varying degradation rates.
