Preparation of a nanoporous Cu–Ag solid solution with enhanced sono-Fenton-like catalytic activity (2019)

Uniform 3D bi-continuous nanoporous Cu-Ag solid solution (NPCS) and nanoporous copper (NPC) were successfully synthesized by dealloying Cu<sub>70</sub>Y<sub>28</sub>Ag<sub>2</sub> and Cu<sub>72</sub>Y<sub>28</sub> metallic glasses, respectively, which was confirmed by using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The SEM and TEM images show that the ligament size of NPCS (<i>d</i> <sub>SEM</sub> = 65 nm, <i>d</i> <sub>TEM</sub> = 45 nm) is much smaller than that of NPC (<i>d</i> <sub>SEM</sub> = 402 nm, <i>d</i> <sub>TEM</sub> = 370 nm), which reveals that the ligaments of NPC can be significantly refined by the substitution of 2 at% Ag for Cu in the amorphous precursor. The obtained NPCS exhibits much larger specific surface area and higher total pore volume (<i>S</i> <sub>BET</sub> = 8.34 m<sup>2</sup> g<sup>-1</sup>, <i>V</i> <sub>p</sub> = 0.093 cm<sup>3</sup> g<sup>-1</sup>) compared to NPC (<i>S</i> <sub>BET</sub> = 1.77 m<sup>2</sup> g<sup>-1</sup>, <i>V</i> <sub>p</sub> = 0.050 cm<sup>3</sup> g<sup>-1</sup>). Furthermore, the catalytic activities of the samples were evaluated by decomposing methyl orange (MO) dye under the irradiation of ultrasound. The results show that NPCS with an extreme fine microstructure displayed superior sono-Fenton-like catalytic activity compared to NPC and commercial copper foil.

A new Z' = 1 crystal structure of quinoxaline (or 1,4-diaza-naphthalene), C(8)H(6)N(2), with one-fifth the volume of the earlier known Z' = 5 structure was obtained by means of an in situ cryocrystallization technique.
VALUATION AND OPTIMIZATION OF INTELLECTUAL CAPITAL: A MULTICRITERIA ANALYSIS (2013)

The present competitive environment of the business world exerts a constant pressure on the valuation and measurement of the key organizational assets. These include Intellectual Capital, competitive intelligence and also knowledge management. This paper presents and applies a model to evaluate intangible assets employing a Multicriteria Decision Aiding method. The focus on Multicriteria Decision Aiding was adopted following a preliminary selection of multicriteria methods, opting to make use of the ELECTRE (Elimination and Choice Translating Reality) family of methods and, in particular, the multicriteria method ELECTRE TRI. This Valuation and optimization of intellectual capital: A multicriteria analysis method makes it possible not only to evaluate and measure intangible assets such as Intellectual Capital, but also to prescribe policies for optimizing intangible assets or, in other words, how and where the organization should invest, at a minimum effort, in order to improve its market value. The conclusions of the paper lead to a vision of new possibilities for the application of the analytical methodology for the valuation of Intellectual Capital. It is worth highlighting the fact that the analysis of the valuation and optimization of intangible assets transcends the ambit of one simple area of knowledge. It is to be found in various areas of knowledge, combining methods and concepts which transcend the ambit of the decision sciences, administration, accounting, financial theory, and operational research itself, relying on a multidisciplinary vision of the organization.
Effect of esophageal intraluminal mechanical and chemical stressors on salivary epidermal growth factor in humans. (1993)

Although various animal and clinical studies have demonstrated the significant effect of salivary epidermal growth factor (sEGF) on esophageal morphology and function, its secretory patterns still remain inadequately explored. Therefore, we have studied the impact of esophageal mechanical and chemical stimuli on sEGF in humans. sEGF was measured in saliva collected during basal conditions, chewing of parafilm, placement of esophageal tubing, inflation of intraesophageal balloons, and perfusion with NaCl, HCl, and HCl/pepsin solutions. The concentration of sEGF was measured with a radioimmunoassay kit from Amersham (Arlington Heights, IL). The concentration of sEGF in basal saliva was (mean +/- SEM) 2.08 +/- 0.22 ng/ml. Chewing the parafilm resulted in a significant decline of sEGF concentration to the value of 1.39 +/- 0.16 ng/ml (p < 0.0005). Similar decline in sEGF concentration also prevailed after placement of intraesophageal tubing (p < 0.03), and inflation of intraesophageal balloons (p < 0.01). This decline intensified significantly when prolonged esophageal perfusion with saline was implemented (p < 0.03 vs. tubing). Substitution of NaCl with HCl in the second and third perfusion periods prevented the decline in sEGF concentration, whereas HCl accompanied by pepsin enhanced sEGF concentration. The rate of sEGF output was 0.90 +/- 0.13 ng/min during basal conditions and increased significantly during parafilm chewing (1.53 +/- 0.25 ng/min; p < 0.05). However, sEGF secretion during both placement of esophageal tubing and inflation of balloons increased 4.1- and 4.9-fold, respectively (p < 0.002 and < 0.00005), over the basal value, and 2.4- and 2.9-fold, respectively, over the parafilm stimulated secretion. Subsequently, we observed a further significant decline of sEGF output (p < 0.05) which was sustained during perfusion of the esophagus with saline. Interestingly, esophageal perfusion with HCl prevented the decline of sEGF secretion observed during perfusion with saline. sEGF output during esophageal perfusion with HCl/pepsin exhibited a strong increase, reaching the value of 5.86 +/- 0.70 ng/ml. This value corresponds to a 58% increase over the secretory rate observed during mechanical stimulation by placement of esophageal tubing (3.71 +/- 0.47; p < 0.05). HCl/pepsin-induced potentiation of sEGF secretion was also highly significantly increased over both the value recorded during basal (p < 0.0005) and parafilm-stimulated (p < 0.002) conditions. Subsequent substitution of HCl/pepsin solution with a final saline perfusate still maintained enhanced sEGF output, compared with both basal (p < 0.02) and parafilm-stimulated conditions (p < 0.02).(ABSTRACT TRUNCATED AT 400 WORDS)

Early warning surveillance of drinking water by photoionization/mass spectrometry (2005)

Increased terrorist activity is raising concerns about the safety of water supplies. Early warning systems that are accurate and fast are needed to deploy effective strategies for rapid response. A new analyzer based on photoionization (PI) and quadrupole ion trap, time‐of‐flight (QitTof) mass spectrometry (MS) offers high‐speed, high‐throughput screening and molecular identification of chemical weapons threats and other hazardous compounds. A growing number of municipalities and government facilities are adopting this new screening instrumentation to help safeguard public drinking water. This article reviews the strategy being taken by cities such as Phoenix, Ariz., to develop an early warning capability based on the PI/QitTof MS screening technology. The screening technology can detect a wide range of compounds at subacute concentrations with no sample preparation and a sampling cycle time of about 45 s.
Alpha-Subunit Positions Methionine 180 and Glutamate 214 of Pseudomonas stutzeri OX1 Toluene- o -Xylene Monooxygenase Influence Catalysis (2005)

Alpha-subunit position M180 of toluene-o-xylene monooxygenase influences the regiospecific oxidation of aromatics (e.g., from o-cresol, M180H forms 3-methylcatechol, methylhydroquinone, and 4-methylresorcinol, whereas the wild type forms only 3-methylcatechol). Position E214 influences the rate of reaction (e.g., E214G increases p-nitrophenol oxidation 15-fold) by controlling substrate entrance and product efflux as a gate residue.
A Single Mutation, RecBD1080A, Eliminates RecA Protein Loading but Not Chi Recognition by RecBCD Enzyme (1999)

Homologous recombination and double-stranded DNA break repair in Escherichia coli are initiated by the multifunctional RecBCD enzyme. After binding to a double-stranded DNA end, the RecBCD enzyme unwinds and degrades the DNA processively. This processing is regulated by the recombination hot spot, Chi (chi: 5'-GCTGGTGG-3'), which induces a switch in the polarity of DNA degradation and activates RecBCD enzyme to coordinate the loading of the DNA strand exchange protein, RecA, onto the single-stranded DNA products of unwinding. Recently, a single mutation in RecB, Asp-1080 --> Ala, was shown to create an enzyme (RecB(D1080A)CD) that is a processive helicase but not a nuclease. Here we show that the RecB(D1080A)CD enzyme is also unable to coordinate the loading of the RecA protein, regardless of whether chi sites are present in the DNA. However, the RecB(D1080A)CD enzyme does respond to chi sites by inactivating in a chi-dependent manner. These data define a locus of the RecBCD enzyme that is essential not only for nuclease function but also for the coordination of RecA protein loading.

These findings open a completely new perspective to study tumor vasculature and to uncover NOVA2 as a potential source of biomarkers and therapeutic targets based on AS isoforms.
Evaluation of IR-HARQ schemes in FBMC/OQAM systems with imperfect CSIR (2017)

This paper characterizes the sources of distortion of offset-QAM based filter bank multicarrier systems when perfect channel state information at the receiver (CSIR) is not available. The statistical information of the distortion reveals that the mapping scheme, which determines how symbols are inserted in the frequency-time grid, can be optimized to reduce the impact of the estimation error. Moreover, the distortion analysis has been exploited to design variable incremental redundancy hybrid automatic repeat request (IR-HARQ) schemes. Numerical results show that the algorithm devised in this work guarantees the target block error rate (BLER) in low mobility scenarios. In addition, the proposed variable IR-HARQ scheme allows to relinquish up to 75 % of the resources to other users when the initial transmission fails.
Functional characterization of the basolateral rat liver organic anion transporting polypeptide (1994)

To characterize the transport functions of a recently cloned basolateral organic anion transporting polypeptide of rat hepatocytes we performed further kinetic transport and substrate cis-inhibition studies in organic anion-transporting polypeptide-cRNA injected Xenopus laevis oocytes. The studies demonstrate saturable Na(+)-independent sulfobromophthalein (Michaelis-Menten constant, 1.5 mumol/L) and taurocholate (Michaelis-Menten constant, 50 mumol/L) uptake by organic anion-transporting polypeptide. Sulfobromophthalein uptake was inhibited by the following organic anions: 0.01 mmol/L bilirubin (43%), 0.1 mmol/L indocyanine green (81%), 0.1 mmol/L 4,4'-diisothiocyanatostilbene-2,2'-disulfonic acid (DIDS; 52%) and 1 mmol/L probenecid (74%). Competitive inhibition was shown for indocyanine green (inhibition constant about 1.3 mumol/L). Sulfobromophthalein and taurocholate uptakes were also inhibited by cholate, chenodeoxycholate, deoxycholate and ursodeoxycholate, as well as their glycine and taurine conjugates. Organic anion-transporting polypeptide also mediated uptake of glycocholate, tauroursodeoxycholate and taurochenodeoxycholate. No cis-inhibition of sulfobromophthalein uptake was seen in the presence of ATP, para-aminohippuric acid, bumetanide, digitoxin, reduced glutathione, leukotriene C4, nicotinic acid, ouabain, oxalate, rifampicin, succinate or sulfate. Furthermore, radioactively labeled para-aminohippuric acid, alpha-ketoglutarate and reduced glutathione were not taken up by organic anion-transporting polypeptide in cRNA-injected frog oocytes. These data confirm that organic anion-transporting polypeptide represents a novel hepatocellular organic anion uptake system that can mediate Na(+)-independent transport of monovalent (e.g., bile acids) and divalent (e.g., sulfobromophthalein and indocyanine green) cholephilic organic anions.(ABSTRACT TRUNCATED AT 250 WORDS)
Erosion By Circular Turbulent Wall Jets (1977)

Summary This paper presents an experimental study on the erosion of loose beds of sand and polystyrene by circular turbulent wall jets ol" air and water. Characteristics of the scour hole have been observed during its growth and also in the final asymptotic state. These profiles have in general been found to be similar when expressed in dimensionless forms with some dispersion near the ridge which forms at the downstream end of the hole. The length scales (made dimensionless with the jet diameter) and the dimensionless characteristic time have been found to be functions of mainly the densimetric Froude number. Some observations have also been made on the behaviour ol'the jet in the asymptotic erosion state.
An Optimal Three-Dimensional Drone Layout Method for Maximum Signal Coverage and Minimum Interference in Complex Pipeline Networks (2021)

In daily pipeline inspection, it is significant to ensure good network communication and security. With the development of drone technology, it is possible to apply drones as air routers to collect information from pipeline networks and transmit it to pipeline inspectors. It is also crucial to achieve optimal drone deployment in pipeline networks. This article proposes a two-phase evolution optimal 3-D drone layout algorithm to deploy drones in pipeline networks. First, a 3-D pipeline graph model is designed to represent the possible projection position of drones, and the objective function is proposed for optimal drone deployment. Then, in the first phase, based on the features of the 3-D pipeline graph, the drone flight rules and constraint conditions are presented to calculate the number of drones and the initial layout sequence. In the second phase, according to the objective function and the above results, every drone is continuously moved in a small area to achieve a tradeoff between signal coverage and interference. Moreover, the key parameters of the objective function can be discussed to further optimize drone deployment. Simulation results are presented to illustrate the effectiveness and advantages of the proposed algorithm.
Oil Shale Development in the United States : Prospects And Policy Issues (2005)

Public and private institutions in the United States have long been home to a variety of art works, antiquities, and ethnological materials. For years, these collections have been seen as important archives that allow present and future generations to enjoy, appreciate, and value the art of all cultures. In the past decade, however, questions have been raised as to exactly what constitutes legal and ethical ownership of art and other cultural property. Some observers believe that art and ethnological materials should remain in source countries, and have lobbied for an end to art trading. Recent changes to U.S. law may curtail both private and public collecting. Contributors to Who Owns the Past? include legal scholars, museum professionals, anthropologists, archaeologists, and collectors. In clear, nontechnical language, they provide a comprehensive overview of the development of cultural property law and practices, as well as recent case law affecting the ability of museums and private collectors to own art from other countries. Topics covered include rights to property, ethical ownership, the public responsibilities of museums, threats to art from war and development, and international cooperation to preserve collections in the developing world. Engaging all perspectives on this debate, Who Owns the Past? challenges all who care about the arts to work together toward policies that consider traditional American interests in securing cultural resources, and respect international concerns over loss of heritage.

Laser patterning for reel-to-reel production of organic photovoltaic (OPV) devices (2015)

The direct write and non-contact nature of laser patterning is highly desirable as it is compatible with integration in rollto-roll production lines. The reduced thermal effects of ultrafast lasers are key to obtain selective removal of sensitive, thin film layers (&lt;0.2µm). In this work, diode-pumped solid state (DPSS) picosecond and femtosecond pulse duration lasers are compared to identify the laser parameters and conditions required to produce high efficiency organic photovoltaics.

Effective design of multiple hollow cathode electrode to enhance the density of rf capacitively coupled plasma (2010)

Multiple-hole electrode rf capacitively coupled plasma is experimentally studied to determine the optimum condition for high-density plasma discharge. The plasma density was measured at various pressures, hole diameters, rf currents, and gas species conditions. The bulk plasma intrusion in the hole and the ionization avalanche in the sheath region facilitated high-density plasma generation when the diameter of the hole is slightly wider than triple the sheath length. The analytic design of the efficient multihole electrode for high-density rf capacitively coupled plasma discharge will be discussed.
