How to Impede Hydrogen Evolution on Carbon Based Materials? (2022)

Hydrogen is a highly attractive zero-emission energy sector. However, in many electrochemical systems, such as carbon dioxide reduction, batteries and supercapacitors hydrogen evolution reaction (HER) is an undesired competing reaction. It is therefore important to tailor these electrochemical systems in order to minimise hydrogen production. Carbon black materials are often added to the catalyst layers as they are low cost, abundant, inert, and have a high conductivity and surface area. This work has investigated HER activities for seven different commercial carbon materials to identify the required structural properties of carbon for minimizing the hydrogen evolution reaction. Rotating disk electrode, X-ray diffraction, and nitrogen adsorption/ desorption were used to determine the electrochemical and physical characteristics of the carbon materials. An on-chip electrochemical mass spectrometer was used to further probe the gaseous products being produced at the electrode insitu; we established that the exact onset of the HER at -0.4 V vs RHE, as shown in Figure 1. Furthermore, we have correlated our electrochemical experiments to earlier characterization data on the same carbon materials, including: X-ray photoelectron spectroscopy, elemental analysis (e.g. Fe, H, S, C) using neutron activation analysis. 1 Our results indicate that the most graphitic carbons with low amount of metal impurities are the best for inhibiting H 2 evolution.

Brain-on-a-chip microsystem for investigating traumatic brain injury: Axon diameter and mitochondrial membrane changes play a significant role in axonal response to strain injuries (2014)

Diffuse axonal injury (DAI) is a devastating consequence of traumatic brain injury, resulting in significant axon and neuronal degeneration. Currently, therapeutic options are limited. Using our brain-on-a-chip device, we evaluated axonal responses to DAI. We observed that axonal diameter plays a significant role in response to strain injury, which correlated to delayed elasticity and inversely correlated to axonal beading and axonal degeneration. When changes in mitochondrial membrane potential (MMP) were monitored an applied strain injury threshold was noted, below which delayed hyperpolarization was observed and above which immediate depolarization occurred. When the NHE-1 inhibitor EIPA was administered before injury, inhibition in both hyperpolarization and depolarization occurred along with axonal degeneration. Therefore, axonal diameter plays a significant role in strain injury and our brain-on-a-chip technology can be used both to understand the biochemical consequences of DAI and screen for potential therapeutic agents.
Überexpression von Stathmin/Op18 in der humanen Hepatokarzinogenese – Regulation und therapeutische Optionen (2007)

Stathmin/Op18, ein Mikrotubulus-destabilisierendes Phosphoprotein, ist essentiell für den Auf- und Abbau des Spindelapparates während der Mitose. Eine Überexpression von Stathmin nach Funktionsverlust von p53 konnte bereits in anderen Tumorentitäten (z.B. Mammakarzinom) als zentraler protumorigener Mechanismus identifiziert werden; vergleichbare Studien für das hepatozelluläre Karzinom (HCC) liegen bislang nicht vor.

Effects of selective oral antimicrobial prophylaxis and systemic antibiotics on the fecal flora and fecal beta‐aspartylglycine concentration in patients with acute leukemia (1989)

The influence of selective oral antimicrobial prophylaxis (SOAP) and systemic antibiotic treatment (SAT) on the intestinal flora of fourteen granulocytopenic patients was investigated. For SOAP, patients received Cotrimoxazole, Polymyxin and Nystatin; Gentamicin, Ticarcillin and Cefuroxime were administered for SAT. Under SOAP, a complete elimination of Enterobacteriaceae and a marked reduction of yeasts and staphylococci was found. A reduction in the number of anaerobic species was also observed; however, the concentration of anaerobic bacteria remained constant. In contrast, additional systemic antibiotic treatment caused a significant reduction of aerobic as well as anaerobic bacteria, except for microorganisms pathogenic to neutropenic patients (i.e. Staphylococcus epidermidis and Candida sp.). The fecal concentration of beta-aspartylglycine was inversely correlated with the presence of anaerobic bacteria.
Coding for a coherent DS-CDMA system employing an MMSE receiver in a Rayleigh fading channel (2000)

This paper analyzes the performance of a convolutionally coded code-division multiple-access system, which employs a linear, minimum mean-square error (MMSE) receiver for interference suppression. A flat, Rayleigh fading channel is considered, where convolutional encoding and interleaving are employed in order to combat the effects of the fading. Theoretical results are derived for the average bit-error probability of the MMSE receiver, where the optimum tap weights for the adaptive filter are determined by the solution of the Wiener-Hopf equations. Simulation results showing the average bit-error rate of the MMSE receiver are also presented, which incorporate the effects of recursive least squares adaptation, channel estimation using pilot symbol-assisted modulation, and finite interleaving. Results show that the MMSE receiver with coding can provide a substantial gain over the matched-filter receiver in a rapidly varying, Rayleigh fading channel. The results also reiterate the fact that lower rate codes are not necessarily the best choice when used with the MMSE receiver.
Monoclonal antibodies against different epitopes on colonization factor antigen I of enterotoxin-producing Escherichia coli (1988)

Hybridoma-secreting monoclonal antibodies (MAbs) against colonization factor antigen I (CFA/I) were produced by the fusion of spleen cells from immunized BALB/c mice with F/O myeloma cells. The 25 MAbs with the highest antibody titer against CFA/I, as determined by an enzyme-linked immunosorbent assay, were studied for specificity and the capacity to agglutinate CFA/I-carrying bacteria. Most of the MAbs agglutinated a majority of 16 CFA/I-positive strains tested but not any of a number of CFA-deficient mutants or strains carrying other colonization factors (CFA/II and CFA/IV). One MAb that agglutinated all the CFA/I-positive strains and one MAb that did not agglutinate any of these strains were compared for their reactivities with different preparations of CFA/I. Whereas both MAbs bound to or could be inhibited by isolated CFA/I fimbriae as well as the subunit protein, only the agglutinating MAb bound to CFA/I, as expressed on whole bacteria. The nonagglutinating MAb, on the other hand, bound considerably better than the agglutinating MAb to a peptide corresponding to the 46 N-terminal amino acid residues of the CFA/I subunit protein. These results suggest that the two MAbs are directed against different epitopes on CFA/I.

IBM Puts Fast Chips on a New Footing (1998)

IBM announced last week that it will soon begin producing microprocessor chips embodying a technology that it says could boost operating speeds by as much as 35%. The new chips are also expected to use about a third less electricity than today's microprocessors, extending battery life for portable devices such as cellular phones and handheld computers. Competitors say IBM is betting on the wrong horse. But if the gamble pays off, the new chips could help extend Moore's law, the famous trend of performance improvements that has driven advances in microelectronics for decades but is expected to begin flattening out soon.
Initial Ground-based Thermospheric Wind Measurements Using Doppler Asymmetric Spatial Heterodyne Spectroscopy (DASH) (2010)

We present the first thermospheric wind measurements using a Doppler Asymmetric Spatial Heterodyne (DASH) spectrometer and the oxygen red-line nightglow emission. The ground-based observations were made from Washington, DC and include simultaneous calibration measurements to track and correct instrument drifts. Even though the measurements were made under challenging thermal and light pollution conditions, they are of good quality with photon statistics uncertainties between about three and twenty-nine meters per second, depending on the nightglow intensity. The wind data are commensurate with a representative set of Millstone Hill Fabry-Perot wind measurements selected for similar geomagnetic and solar cycle conditions.
PREDATION ON NEONATE LARVAE OF DIAPREPES ABBREVIATUS (COLEOPTERA: CURCULIONIDAE) IN FLORIDA CITRUS: TESTING FOR DAILY PATTERNS OF NEONATE DROP, ANT PREDATORS AND CHEMICAL REPELLENCY (2003)

The root weevil, Diaprepes abbreviatus (L.), is a major pest of Florida citrus. When neonate larvae hatch from egg masses in the citrus canopy and drop to the soil surface before burrowing down to the roots for feeding, they are vulnerable to ant predation. However, neonates are reported to produce a chemical repellent that lasts up to four days and reduces ant predation by about 40%. We assessed the daily pattern of neonate drop from egg masses under laboratory conditions (24°C, 70% RH, L:D = 12:12), examined the role of ants as predators of neonates (<48 h post hatch) on the soil surface in three citrus groves in central Florida, and tested for chemical repellency in the field by comparing predation rates on 5-day versus 1-2 h old neonates. Neonate drop was not well synchronized within or among egg masses, occurred during all hours of the light and dark phases, and extended over 5 to 23 h (mean = 11.97, SE = 0.866) for individual egg masses (n = 29). However, the drop rate was highest during the second half of the light phase (52.4%) and lowest during the second half of the dark phase (8.0%). Predation occurred in 104 of 199 replicates (52.3%) in the three groves with a total of 475 of the 3980 larvae (11.9%) removed by predators within 20 mins. Predation pressure varied within and among groves, and involved eight ant species (Hymenoptera: Formicidae) and a single predation event by a nymph of the big-eyed bug, Geocoris floridanus Blatchley (Hemiptera: Lygaeidae). For data pooled among groves, the red imported fire ant, Solenopsis invicta Buren, was responsible for 29.5% of the predation, Pheidole moerens Wheeler 27.8%, Dorymyrmex reginicula (Trager) 9.7%, Brachymyrmex obscurior Forel 8.8%, Dorymyrmex bureni (Trager) 8.6%, Cardiocondyla emeryi Forel 8.0%, Paratrechina bourbonica Forel 4.8%, and Pheidole morrisi Forel 2.5%. In our test for age-dependent chemical repellency, a total of 2620 of the 3840 neonates (68.2%) were preyed upon within 30 mins but the predation rate on old versus young neonates did not differ at 68.8% and 67.7%, respectively. In this experiment, 368 of the predation events (14.0%) were observed directly with P. moerens responsible for 62.5%, S. invicta 25.3%, C. emeryi 10.1%, B. obscurior 1.4%, Cardiocondyla wroughtonii (Forel) 0.5%, and D. bureni 0.3%. We conclude that ants are important predators of Diaprepes neonates in central Florida citrus groves and have potential for a conservation biological control program.
Late postnatal HIV infection in children born to HIV-1-infected mothers in a high-income country (2010)

Late postnatal HIV-1 infection can rarely be diagnosed in the absence of known breastfeeding in high-income countries. Our results highlight the need for a maintained close follow-up of the noninfected children even after 6 months, especially when there are risk factors for intrafamilial viral transmission.
A Scalable Multi-Replication Framework for Data Grid (2006)

Existing replica services on the Grid we know to date assumes point-to-point communication and file transfer protocol. As such, when hundreds to thousands of hosts on the Grid access a single dataset simultaneously, bottlenecks in networks and/or the data servers will hinder performance significantly. Instead, our replication framework couples efficient, multicast techniques with a replica catalog that automatically detects simultaneous access to the replica by multiple nodes. As a prototype, we have designed and built a portable, XML-based replica location service accounting for such parallel transfer requests, and coupled it with a O(1) bulk file transfer system Dolly+[6]. The benchmarks show that the system is scalable and effective in reducing replication costs significantly in cluster-based replication scenarios.

THE ROLE OF SINGLET OXYGEN IN PHOTOOXIDATION OF EXCITABLE CELL MEMBRANES (1979)

Abstract— Giant nerve axons from lobsters were photooxidized by visible light from a Xe arc using eosin Y, rose bengal and methylene blue as sensitizers. The degree of modification was assayed as the rate constant for block of sodium channels during illumination. Protection or enhancement of modification was tested for several reagents known to interact with singlet oxygen. Deuterium oxide enhanced the modification up to 57% while sodium azide protected up to 60%. β ‐Carotene, triethylamine and DABCO exerted no effect. From a consideration of the probable low polarity environment of the sensitization sites and diffusional restrictions on reagents it is concluded that intramembranously created singlet oxygen plays a significant role in membrane modification.

Hydrodynamic microfabrication via “on the fly” photopolymerization of microscale fibers and tubes (2004)

A microfluidic apparatus capable of creating continuous microscale cylindrical polymeric structures has been developed. This system is able to produce microstructures (e.g. fibers, tubes) by employing 3D multiple stream laminar flow and "on the fly"in-situ photopolymerization. The details of the fabrication process and the characterization of the produced microfibers are described. The apparatus is constructed by merging pulled glass pipettes with PDMS molding technology and used to manufacture the fibers and tubes. By controlling the sample and sheath volume flow rates, the dimensions of the microstructures produced can be altered without re-tooling. The fiber properties including elasticity, stimuli responsiveness, and biosensing are characterized. Responsive woven fabric and biosensing fibers are demonstrated. The fabrication process is simple, cost effective and flexible in materials, geometries, and scales.
What does lie at the Milky Way centre? Insights from the S2-star orbit precession (2021)

ABSTRACT It has been recently demonstrated that both, a classical Schwarzschild black hole (BH), and a dense concentration of self-gravitating fermionic dark matter (DM) placed at the Galaxy centre, can explain the precise astrometric data (positions and radial velocities) of the S-stars orbiting Sgr A*. This result encompasses the 17 best resolved S-stars, and includes the test of general relativistic effects such as the gravitational redshift in the S2-star. In addition, the DM model features another remarkable result: The dense core of fermions is the central region of a continuous density distribution of DM whose diluted halo explains the Galactic rotation curve. In this Letter, we complement the above findings by analysing in both models the relativistic periapsis precession of the S2-star orbit. While the Schwarzschild BH scenario predicts a unique prograde precession for S2, in the DM scenario, it can be either retrograde or prograde, depending on the amount of DM mass enclosed within the S2 orbit, which, in turn, is a function of the DM fermion mass. We show that all the current and publicly available data of S2 cannot discriminate between the two models, but upcoming S2 astrometry close to next apocentre passage could potentially establish if Sgr A* is governed by a classical BH or by a quantum DM system.
Matchmaking using Fuzzy Analytical Hierarchy Process, Compatibility Measure and Stable Matching for Online Matrimony in India (2012)

ABSTRACT Use of online matrimony for matchmaking is rapidly growing in India. One of the major difficulties faced by the users of such websites is the long time taken to realize the matches. We propose an integrated approach to matchmaking in e‐matrimony environment using fuzzy analytical hierarchy process considering multiple criteria involved in the process. The objective of the study is to enable users to search their partners effectively and efficiently and narrow down to the desired matches so that the chances of matchmaking through online portal are maximized. A compatibility index, that is match metric, is developed that enhances the probability of matchmaking with reduction in lead time. Furthermore, Gale‐Shapley stable matching algorithm is used to help customers obtain the desired shortlist of profiles with a suggested stable match. An illustrated hypothetical example of matchmaking using an Indian matrimony portal is presented, and the use of the proposed methodology is demonstrated. Copyright © 2012 John Wiley &amp; Sons, Ltd.
