Beauveria bassiana Culturing and Harvesting for Bioassays With House Flies (2020)

The entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Cordycipitaceae) has been widely studied against a wide range of arthropod pests, including many of medical and veterinary importance. New investigators must sort through a wide array of published methods for the production, harvest, storage, and bioassay methods for this pathogen. Simplified methods for production of conidia using Sabouraud dextrose agar with yeast (SDYA) plates and two conidial harvesting methods are described. Dry harvesting yields conidia that are ready to incorporate into dusts and food baits, but the fungal product includes mycelial debris that can hamper quantification and introduces variable amounts of unwanted bulk. Wet harvesting with filtration produces a cleaner product that is immediately ready for testing in liquid formulations. Examples of bioassays with house flies are presented that include conidia applied topically to the dorsal thorax for dose-mortality assays and conidial suspensions applied to filter paper disks for concentration mortality assays.
The first experiment in the world of robotic telesurgery for laparoscopy carried out by means of satellites networks and optical fibres networks on 7th July 1993 (2002)

This paper describes the significance in human, scientific and technical terms of the first experiment of robotic telesurgery effected between the Telerobotics Laboratory of the Politecnico di Milano and the Jet Propulsion Laboratory, NASA, in Pasadena California, on 7 July 1993. An Italian surgeon controlled from the USA an Italian robot in the Telerobotics Laboratory in such a way that the robot performed a biopsy, on a model containing the organs of a pig, carrying out an aspiration of organic material and two incisions for the commencement of the surgical operation of laparoscopy. Transmission was effected by means of a double satellite link with three stations-one in Italy, one in New York and one in Pasadena and two geostationary satellites, the first over the Atlantic and the second over the United States. The route length of the signals was 150,000 km in each direction and the two centres are 14,000 km apart.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Carbon Dioxide Conversion on Supported Metal Nanoparticles: A Brief Review (2023)

The increasing concentration of anthropogenic CO2 in the air is one of the main causes of global warming. The Paris Agreement at COP 21 aims to reach the global peak of greenhouse gas emissions in the second half of this century, with CO2 conversion towards valuable added compounds being one of the main strategies, especially in the field of heterogeneous catalysis. In the current search for new catalysts, the deposition of metallic nanoparticles (NPs) supported on metal oxides and metal carbide surfaces paves the way to new catalytic solutions. This review provides a comprehensive description and analysis of the relevant literature on the utilization of metal-supported NPs as catalysts for CO2 conversion to useful chemicals and propose that the next catalysts generation can be led by single-metal-atom deposition, since in general, small metal particles enhance the catalytic activity. Among the range of potential indicators of catalytic activity and selectivity, the relevance of NPs’ size, the strong metal–support interactions, and the formation of vacancies on the support are exhaustively discussed from experimental and computational perspective.
A hardware virtual machine for networked reconfiguration (2002)

Networked reconfiguration is an enabling technology for cost effective service deployment and maintenance. A hardware virtual machine to enable this networked reconfiguration is presented. An abstract FPGA model is the core of such a hardware virtual machine. Based on this abstract FPGA model, the traditional implementation flow of FPGA has been separated into two parts: the service provider's side and client's side. We show how to split the FPGA design flow to enable this networked reconfiguration and present first results in the efficiency of the byte files for a hardware virtual machine.

Assessment of the Physical and Mechanical Properties of Permafrost in Nunavik, Quebec, Canada (2019)

Nunavik is a territory in Northern Quebec where 14 communities depend essentially on aerial transportation for their subsistence, economic development, and quality of life. Some airport runways built on permafrost in the late 80s showed worrying degradation signs only a few years after construction. The effect of runway embankments on the thermal regime at the embankment toes and where drainage is deficient, among other things, is well documented throughout the literature. These phenomena, as well as the general permafrost degradation, are amplified by climate changes, especially in northern regions. Because the permafrost degradation is worrying for transportation infrastructure, a project was undertaken to characterize the physical and mechanical properties of some permafrost soils in Northern Quebec, with the objective to assess their creep and thaw sensitivity. Frozen core samples were recovered at seven airstrips and two access roads, and undisturbed specimens were brought back to Laval University geotechnical laboratory. The samples from the most critical and representative study sites were subjected to basic geotechnical characterization along with triaxial creep. The creep tests allowed obtaining estimates of the creep rate for the soils at different deviatoric stress and temperatures. As for the thaw consolidation tests, they allowed estimating the settlements associated with a potential thawing of permafrost for various ice contents. The present paper focuses on the creep behavior. With the available ground thermal regimes and climate change scenarios, the results allow anticipating the thaw and creep settlements for some soils in Nunavik and can be used as part of a global adaptation strategy for infrastructure built on permafrost.
Correction: Systemic Complement Activation in Age-Related Macular Degeneration (2008)

Dysregulation of the alternative pathway (AP) of complement cascade has been implicated in the pathogenesis of agerelated macular degeneration (AMD), the leading cause of blindness in the elderly.To further test the hypothesis that defective control of complement activation underlies AMD, parameters of complement activation in blood plasma were determined together with disease-associated genetic markers in AMD patients.Plasma concentrations of activation products C3d, Ba, C3a, C5a, SC5b-9, substrate proteins C3, C4, factor B and regulators factor H and factor D were quantified in patients (n = 112) and controls (n = 67).Subjects were analyzed for single nucleotide polymorphisms in factor H (CFH), factor B-C2 (BF-C2) and complement C3 (C3) genes which were previously found to be associated with AMD.All activation products, especially markers of chronic complement activation Ba and C3d (p,0.001), were significantly elevated in AMD patients compared to controls.Similar alterations were observed in factor D, but not in C3, C4 or factor H. Logistic regression analysis revealed better discriminative accuracy of a model that is based only on complement activation markers Ba, C3d and factor D compared to a model based on genetic markers of the complement system within our study population.In both the controls' and AMD patients' group, the protein markers of complement activation were correlated with CFH haplotypes.This study is the first to show systemic complement activation in AMD patients.This suggests that AMD is a systemic disease with local disease manifestation at the ageing macula.Furthermore, the data provide evidence for an association of systemic activation of the alternative complement pathway with genetic variants of CFH that were previously linked to AMD susceptibility.
Refined localisation of the genes for nebulin and titin on chromosome 2q allows the assignment of nebulin as a candidate gene for autosomal recessive nemaline myopathy. (1998)

A locus for autosomal recessive nemaline myopathy (NEM2) has been assigned by linkage analysis to a 13-cM region between the markers D2S150 and D2S142 on 2q21.2-q22. The genes for the giant muscle proteins nebulin and titin have previously been assigned by FISH to 2q24.1-q24.2 and 2q31, respectively. By using radiation hybrid mapping, we have reassigned the nebulin gene close to the microsatellite marker D2S2236 on 2q22 and the titin gene to the vicinity of the markers D2S384 and D2S364 on 2q24.3. The genomic orientation of the nebulin gene was determined as 5'-3' and of TTN as 3'-5' from the centromere. We conclude that the nebulin gene resides within the candidate region for NEM2 on the long arm of chromosome 2, while the titin gene is located outside this region.
Faster algorithms for string matching with k mismatches (2000)

The string matching with mismatches problem is that of finding the number of mismatches between a pattern P of length m and every length m substring of the text T. Currently, the fastest algorithms for this problem are the following. The Galil-Giancarlo algorithm finds all locations where the pattern has at most k errors (where k is part of the input) in time O(nk). The Abrahamson algorithm finds the number of mismatches at every location in time O(n√ m log m). We present an algorithm that is faster than both. Our algorithm finds all locations where the pattern has at most k errors in time O(n√k log k). We also show an algorithm that solves the above problem in time O((n + (nk3)/m) log k).
Water Reduction with Visible Light: Synergy between Optical Transitions and Electron Transfer in Au‐TiO2 Catalysts Visualized by In situ EPR Spectroscopy (2013)

Golden electrons: Visible light excites conduction electron transfer from gold particles to support vacancies where they are taken up by protons to produce hydrogen. This transfer process was visualized by in situ EPR spectroscopy.
2D network simulation and luminescence characterization of Cu(In,Ga)Se2 thin film modules (2012)

ABSTRACT Cu(In,Ga)Se 2 thin film modules have achieved a high degree of maturity. A major challenge for a large volume production is the development of inline characterization tools allowing the detection and interpretation of defects and inhomogeneities. The combination of luminescence characterization (electroluminescence and photoluminescence) and electrical 2D network simulation is proposed to detect shunt defects, defective interconnects, and photocurrent inhomogeneities. Additionally, simulation allows the assessment of the impact of such defects on the module performance. Our approach enables the implementation of an early warning system in a production line, helps to identify the origin of a reduced module performance, and enhances the understanding of defects and inhomogeneities.

Binary Fe−Co Alloy Nanoparticles Showing Significant Enhancement in Electrocatalytic Activity Compared with Bulk Alloys (2010)

Microemulsion-based synthesis of Fe−Co alloy nanoparticles has been reported for the first time. Spherical, uniform, and highly monodisperse nanoparticles of Fe75Co25, Fe67Co33, Fe50Co50, and Fe33Co67 with an average size of 20, 25, 10, and 40 nm, respectively, were synthesized. These nanoparticles crystallize in a body-centered cubic cell. A higher cobalt content led to the formation of biphasic mixtures. Energy-dispersive X-ray spectroscopy studies confirmed the Fe/Co ratios. Nanoparticles of the Fe33Co67 alloy show higher hydrogen and oxygen evolution efficiencies (over 100 times) compared with other Fe−Co alloys of nanocrystalline or bulk form. The Fe−Co alloy nanoparticles also show ferromagnetism.
Damage stability and survivability – ‘nailing’ passenger ship safety problems (2013)

With artefacts on human endeavours at sea dating as far back as 6500 BC, it is mind boggling to think that it was not until 250 BC when the first recorded steps to establish the foundation of naval architecture, floatability and stability, were made by Archimedes. It is even more astonishing that practical pertinence and function of these two very basic principles remained dormant for nearly two millennia after this, before the first attempts to convey the meaning of stability to men of practice took place in the eighteenth century by Hoste and Bouguer. Pertinent regulations, especially after accidents involving water ingress and flooding (through subdivision and damage stability), were introduced even much later. Notably, the first Merchant Shipping Act of 1854 addressed subdivision and led eventually and after heavy loss of life to the adoption of the first internationally agreed system of subdivision in SOLAS 1929 (Safety of Life at Sea), while the first specific criterion on residual static stability standards was introduced at the 1960 SOLAS Convention. This ‘tortoise’ pace gave way to the steepest learning curve in the history of naval architecture with the introduction of the probabilistic damage stability rules in the late 60s as an alternative to the deterministic requirements. Prompting and motivating the adoption of a more rational approach to damage stability and survivability necessitated the development of appropriate methods, tools and techniques capable of meaningfully addressing the physical phenomena involved. Within 50 years, this new impetus has climaxed to the ‘zero tolerance’ concept of Safe Return to Port, introduced in July 2009, and to an open proclamation by the Secretary of the International Maritime Organization (IMO) that deterministic requirements have no future. More important, the use of a probabilistic framework and of first-principles tools to address ship safety quantitatively and consistently has given rise to aspirations and henceforth capability in identifying and evaluating the key contributors to passenger ship safety. The revelation was plain and clear, namely: damage stability or, more precisely, lack thereof constitutes by far the key risk contributor for passenger ships. Resolving this problem will be equivalent to solving (‘nailing’) passenger ship safety problems. The author, having played a protagonist role in contemporary developments on damage stability and survivability and having been involved closely in implementing such developments to the design of modern mega-ships, will attempt to provide a succinct account of pertinent developments on damage stability and survivability and demonstrate their implications on passenger ship design and operation.
Design and Benchmark of Iso-Stable High Density 4T SRAM cells for 64MB arrays in 65nm LSTP (2020)

Embedded SRAMs enable high performance operation of processor and become an essential block in modern SoCs. Memory instances occupy almost 70% of area of the embedded microprocessors and constitute a large part of power budget. So, designing dense SRAMs with low leakage power is a key focus for SRAM designers. This paper presents design and benchmark of different topologies of 4T SRAM cells and conventional 6T SRAM cell in 65nm Low Standby Power(LSTP) Technology. Our analysis shows that not only iso-stable 4T cells are 10-25% denser than conventional 6T SRAM cell, they also have upto 65% lower leakage. These density and leakage gains are enabled by a 20% loss in speed which is an acceptable trade-off for higher level caches with multi-cycle access.
Special issue on programmable switches and routers (2001)

This Special Issue of JCN explores architectures and implementation challenges for network elements into which executable software can be safely installed and run during normal operation. Unlike traditional network elements. that are pre-programmed by manufacturers or operators. this new type of element, which is usually but not necessarily a switch or router, can be dynamically programmed and can run multiple instances of ontrol and data processing functions. The applications of multicast, traffic control, and DiffServ implementation are addressed in this issue. Many people working in this area feel that support of multiple virtual private networks. each with its own sustomized control plane. will be an important commercial application in the future. More generally. programmable network element. encourage an open market in control and traffic-processing software. promising cost savings and imaginative new services capabi lities for the operators of future networking infrastructure.
Assessment of the acute effect of trapidil on cardiac hemodynamics by multi-gated blood pool scintigraphy. (1986)

Multi-gated blood pool scintigraphy, a method of clinically proven usefulness for the noninvasive evaluation of cardiac hemodynamics, was used to evaluate the efficacy of trapidil. The longitudinal image of the left ventricle was taken using a gammaray camera equipped with a 30°C slant hole collimator (Siemens model ZLC 75), and the collimator was set in the cranio-caudal direction with amodified LAO. The R waves on the ECG and the second sound on the phonocardiogram were used as synchronizing signals to clarify the target image. The ADAC system II nucleomedical data processor was used for processing and statistical analysis of the data. Ten subjects (9 men and 1 woman at the mean age of 64 years) were injected iv with 100 mg of trapidil over 2 minutes, and the scintigram was taken from immediately after the iv injection. The following results suggested the positive inotropic action with trapidil: 1. lowering of body blood pressure and increase in heart rate (P<0.001); 2. increase in the left ventricular ejection fraction (P<0.01), and increase in cardiac index (P<0.01); 3. increase in maximum left ventricular ejection velocity (P<0.05) and increase in the maximum left ventricular filling velocity (N. S.); 4. increase in the left ventricular work index (P<0.05); and 5. decrease in total systemic vascular resistance (P<0.01).
A histopathological study of anoxic-resuscitated liver allografts. (1997)

The possibility of resuscitating livers after warm ischaemia has been recently suggested. The aim of the present investigation was to analyse the effects of anoxia on the morphology of hepatic cells, to determine whether these effects are reversible after providing a resuscitation period between warm ischaemia (WI) and cooling, and to study the behaviour of the resuscitated liver in the recipient organism. Ten female, Large-White pigs acted as donors for 10 recipient animals of the same kind who received an orthotopic liver graft. Recipients were divided into two groups depending on whether the livers they received had undergone a resuscitation period (Group I (n=5) where animal livers were subjected to 5 min warm ischaemia (WI) without resuscitation, and Group II (n=5) where the livers were subjected to 5 min WI followed by 5 min resuscitation). Morphological and ultrastructural studies of liver cells were performed using light and electron microscopy. ATP, ADP and AMP levels were determined in liver biopsies by high performance liquid chromatography (HPLC). Plasma AST and bilirubin levels in the two groups were compared 24 h after transplantation. After 5 min of anoxia, hepatocytes showed two morphological patterns in response to WI. Some were appreciably condensed with dark mitochondria, peroxisomes and some cytoplasmic vacuoles. Others showed electronlucent organelles, inflamed mitochondria with broken cristae and disorganized endoplasmic reticulum. Hepatocytes showed globular microvilli and bleb formation with migration towards the sinusoids. One hour after the revascularisation of the resuscitated livers, the hepatocytes showed nearly normal morphological characteristics. However, the hepatocytes of non-resuscitated organs continued to show alterations. Kupffer cells were activated in the livers of both experimental groups. Ultrastructural changes and total tissue adenine nucleotide (TAN) levels recovered completely in resuscitated livers soon after transplant. These results suggest that when short WI periods are followed by equivalent periods of resuscitation, the hepatocytes of transplanted livers recover from the effects of anoxia.
