A hybrid Particle swarm optimization -Extreme Learning Machine approach for Intrusion Detection System (2018)

There are several limitations that facing intrusion-detection system in current days, such as high rates of false positive alerts, low detection rates of rare but dangerous attacks. Daily, there are reports of incidents such as major ex-filtration of data for the purposes of stealing identities. Hybrid model's approaches have been widely used to increase the effectiveness of intrusion-detection platforms. This work proposes the extreme learning machine (ELM) is one of the poplar machine learning algorithms which, easy to implement with excellent learning performance characteristics. However, the internal power parameters (weight and basis) of ELM are initialized at random, causing the algorithm to be unstable. The Particle swarm optimization (PSO) is a well-known meta-heuristic which is used in this research to optimize the ELM. Our propose model has been apple based as intrusion detection and validated based on NSL-KDD data set. Our developed model has been compared against a basic ELM. PSO-ELM has outperformed a basic model in the testing accuracy
Advanced Low NOx Combustors for Aircraft Gas Turbines (1976)

The coexistence and interactions among Listeria monocytogenes strains in combination with the structural characteristics of foods, may influence their growth capacity and thus, the final levels at the time of consumption. In the present study, we aimed to evaluate the effect of oxygen availability in combination with substrate micro-structure on growth and inter-strain interactions of L. monocytogenes. L. monocytogenes strains, selected for resistance to different antibiotics (to enable distinct enumeration), belonging to serotypes 4b (C5, ScottA), 1/2a (6179) and 1/2b (PL25) and were inoculated in liquid (Tryptic Soy Broth supplemented with Yeast Extract - TSB-YE) and solid (TSB-YE supplemented with 0.6% and 1.2% agar) media (2-3 log CFU/mL, g or cm<sup>2</sup>), single or as two-strain cultures (1:1 strain-ratio). Aerobic conditions (A) were achieved with constant shaking or surface inoculation for liquid and solid media respectively, while static incubation or pour plated media corresponded to hypoxic environment (H). Anoxic conditions (An) were attained by adding 0.1% w/v sodium thioglycolate and paraffin overlay (for solid media). Growth was assessed during storage at 7 °C (n = 3 × 2). Inter-strain interactions were manifested by the difference in the final population between singly and co-cultured strains. Τhe extent of suppression increased with reduction in agar concentration, while the impact of oxygen availability was dependent on strain combination. During co-culture, in liquid and solid media, 6179 was suppressed by C5 by 4.0 (in TSB-YE under H) to 1.8 log units (in solid medium under An), compared to the single culture, which attained population of ca. 9.4 log CFU/mL or g. The growth of 6179 was also inhibited by ScottA by 2.7 and 1.9 log units, in liquid culture under H and An, respectively. Interestingly, in liquid medium under A, H and An, ScottA was suppressed by C5, by 3.3, 2.4 and 2.3 log units, respectively, while in solid media, growth inhibition was less pronounced. Investigating growth interactions in different environments could assist in explaining the dominance of L. monocytogenes certain serotypes.

Electronic absorption spectrum of the α-1-adamantyl derivative of Michler's hydrol blue (1967)

The close similarity between the absorption spectrum of the α-1-adamantyl derivative of Michler's Hydrol Blue and that of the α-t-butyl derivative strikingly confirms the view that molecular crowding in the latter causes partial deconjugation of one of the dimethylaminophenyl groups.

BANSAI - An optofluidic approach for biomedical analysis (2015)

Abstract Lab-on-a-chip based portable blood analysis systems would allow point-of-care measurements, e.g. in an ambulance, or in remote areas with no fast access to medical care. Such a systemwould provide much faster information about the health of a patient. Here,we present a system that is based on absorption spectroscopy and uses an organic laser, which is tunable in the visible range. The feasibility of the system is shown with a table-top setup using laboratory equipment. Measurements of human albumin show linear behaviour in a range from 2.5 g/L to 60 g/L. In a consecutive setup the system is implemented on a microfluidic chip and is capable of measuring simultaneously transmitted and side scattered intensities, even with ambient light present. Air-suspended grating couplers on polymers are shown as the first element of a lab-on-a-chip implementation.
Methods for the measurement of lipoprotein (a) in the clinical laboratory (1992)

The past few years have seen the introduction of lipoprotein (a) measurements into the clinical laboratory. Besides a number of technical pitfalls, the question of assay standardization remains unresolved. The polymorphic nature of apolipoprotein (a) poses a major problem in the achievement of this standardization.
Parallel Detrended Fluctuation Analysis for Fast Event Detection on Massive PMU Data (2014)

Phasor measurement units (PMUs) are being rapidly deployed in power grids due to their high sampling rates and synchronized measurements. The devices high data reporting rates present major computational challenges in the requirement to process potentially massive volumes of data, in addition to new issues surrounding data storage. Fast algorithms capable of processing massive volumes of data are now required in the field of power systems. This paper presents a novel parallel detrended fluctuation analysis (PDFA) approach for fast event detection on massive volumes of PMU data, taking advantage of a cluster computing platform. The PDFA algorithm is evaluated using data from installed PMUs on the transmission system of Great Britain from the aspects of speedup, scalability, and accuracy. The speedup of the PDFA in computation is initially analyzed through Amdahl's Law. A revision to the law is then proposed, suggesting enhancements to its capability to analyze the performance gain in computation when parallelizing data intensive applications in a cluster computing environment.
Auxiliary resonant commutated soft-switching inverter with bidirectional active switches and voltage clamping diodes (2002)

This paper presents a soft-switching PWM inverter with auxiliary resonant bridge-leg link snubbers on the basis of bidirectional active power switches and voltage clamping diodes. The voltage clamping diodes protect the bidirectional active switches from spike surge voltage caused by the stray energy of auxiliary inductors and parasitic wiring inductances. From a practical point of view, a variety of resonant snubber circuits with the voltage clamping diodes are also presented, Among the variations of the proposed resonant snubber circuits, emitter-emitter connected type IGBT bidirectional active switch and two clamping diodes type snubber circuit is discussed in detail. Furthermore, the performances of the proposed soft switching PWM inverter with the auxiliary resonant bridge-leg link snubber-associated inverter-fed DC to DC converter is demonstrated and evaluated in order to prove feasibility applying for an X-ray high-power high-voltage application.
Non-linear mechanical behavior of the elastomer polydimethylsiloxane (PDMS) used in the manufacture of microfluidic devices (2005)

Polydimethylsiloxane (PDMS) is the elastomer of choice to create a variety of microfluidic devices by soft lithography techniques (eg., [1], [2], [3], [4]). Accurate and reliable design, manufacture, and operation of microfluidic devices made from PDMS, require a detailed characterization of the deformation and failure behavior of the material. This paper discusses progress in a recently-initiated research project towards this goal. We have conducted large-deformation tension and compression experiments on traditional macroscale specimens, as well as microscale tension experiments on thin-film (≈ 50µm thickness) specimens of PDMS with varying ratios of monomer:curing agent (5:1, 10:1, 20:1). We find that the stress-stretch response of these materials shows significant variability, even for nominally identically prepared specimens. A non-linear, large-deformation rubber-elasticity model [5], [6] is applied to represent the behavior of PDMS. The constitutive model has been implemented in a finite-element program [7] to aid the design of microfluidic devices made from this material. As a first attempt towards the goal of estimating the non-linear material parameters for PDMS from indentation experiments, we have conducted micro-indentation experiments using a spherical indenter-tip, and carried out corresponding numerical simulations to verify how well the numerically-predicted P(load-h(depth of indentation) curves compare with the corresponding experimental measurements. The results are encouraging, and show the possibility of estimating the material parameters for PDMS from relatively simple micro-indentation experiments, and corresponding numerical simulations.

Analyzing exception flow in Java programs (1999)

Exception handling mechanisms provided by programming languages are intended to ease the difficulty of developing robust software systems. Using these mechanisms, a software developer can describe the exceptional conditions a module might raise, and the response of the module to exceptional conditions that may occur as it is executing. Creating a robust system from such a localized view requires a developer to reason about the flow of exceptions across modules. The use of unchecked exceptions, and in object-oriented languages, subsumption, makes it difficult for a software developer to perform this reasoning manually. In this paper, we describe a tool called Jex that analyzes the flow of exceptions in Java code to produce views of the exception structure. We demonstrate how Jex can help a developer identify program points where exceptions are caught accidentally, where there is an opportunity to add finer-grained recovery code, and where error-handling policies are not being followed.
The formation of silicon carbide films from disilane derivatives (1994)

The formation of silicon carbide films presents problems arising from the fact that the precursors employed are usually a mixture of compounds. It is demonstrated that high‐quality silicon carbide films (see Figure) can be produced by chemical vapor deposition using easily available disilane derivatives as the precursor. magnified image
<title>Acoustic Holographic Scanning Techniques For Imaging Flaws In Thick Metal Sections</title> (1972)

This paper discusses the application of various scanning configurations used in acoustic holography for imaging internal flaws or voids in thick metal sections; i.e., 10 to 25 cm. The following source-receiving scanning configurations were employed: 1. Simultaneous (inclined plane-wave) source and point receiver scan-ning; 2. Simultaneous (focused) source-receiver scanning employing a simulated acoustic off-axis reference; 3. Simultaneous point source-receiver scanning employing a simulated acoustic off-axis reference; and 4. Stationary (plane-wave) source and point receiver scanning employing a simulated acoustic off-axis reference. All of the above mentioned configurations impose a linear diffraction grating on the hologram and provide the necessary conditions for imaging flaws directly in the projected aperture and separation of the reconstruct-ed images. The flaw images appear two-dimensional as a result of the large difference between the construction and reconstruction wavelengths. Longitudinal magnification is much greater than the lateral magnification and the images appear stretched in depth. However, the hologram does contain the complete depth information of the flaws and this is easily observed by focusing on different planes in the metal sections parallel to the hologram plane (i.e., different depths within the metal section are viewed simply bymanipulation of the optical imaging lens in the reconstruction The images of the internal flaws are viewed by adjusting the lens until the image is in focus. The lateral and longitudinal dimensions of the flaws are then calculated using the conventional image location and magnification equations.
A Unifying Synthesis Approach to the C<sub>18</sub>-, C<sub>19</sub>-, and C<sub>20</sub>-Diterpenoid Alkaloids (2017)

The secondary metabolites that comprise the diterpenoid alkaloids are categorized into C<sub>18</sub>, C<sub>19</sub>, and C<sub>20</sub> families depending on the number of contiguous carbon atoms that constitute their central framework. Herein, we detail our efforts to prepare these molecules by chemical synthesis, including a photochemical approach, and ultimately a bioinspired strategy that has resulted in the development of a unifying synthesis of one C<sub>18</sub> (weisaconitine D), one C<sub>19</sub> (liljestrandinine), and three C<sub>20</sub> (cochlearenine, paniculamine, and N-ethyl-1α-hydroxy-17-veratroyldictyzine) natural products from a common intermediate.
RhoA, RhoB, RhoC, Rac1, Cdc42, and Tc10 mRNA levels in spinal cord, sensory ganglia, and corticospinal tract neurons and long‐lasting specific changes following spinal cord injury (2005)

Inhibition of RhoA has been shown to enhance axonal regeneration following spinal cord injury. Here we mapped mRNA expression patterns of RhoA, B, and C, Rac1, Cdc42, and Tc10 in spinal cord, sensory ganglia, and sensorimotor cortex in uninjured rats, and following spinal cord injury or sham laminectomy. In the intact spinal cord, neurons displayed high levels of Rac1, Cdc42, and Tc10 mRNA hybridization signal. GFAP-immunoreactive astrocytes expressed primarily RhoB and Rac1, while oligodendrocyte-like cells expressed RhoA, Rac1, and Cdc42. Injury caused profound, long-lasting upregulation of RhoA, Rac1, Cdc42, and Tc10 mRNA in the spinal cord, while RhoB was modestly increased and RhoC did not change. GFAP-immunoreactive reactive astrocytes exhibited a dramatic increase of RhoA mRNA expression along with increases of Rac1 and Cdc42. Injury also led to elevation of RhoA, Cdc42, and Tc10 in neurons and modest increases of RhoA, Rac1, and Tc10 in oligodendrocyte-like cells. Laminectomy caused similar, but less pronounced alterations of investigated mRNA species. In dorsal root ganglia neuronal RhoA, Rac1, Cdc42, and Tc10 mRNA levels were increased similarly by spinal cord injury and sham surgery. The CST pyramidal cells expressed Tc10 mRNA and the CST itself was Tc10-immunoreactive. Tc10-immunoreactivity disappeared distal to injury. We conclude that there are gene-specific patterns of expression of the six different Rho-GTPases in normal spinal cord and dorsal root ganglia, and that specific changes of temporal and spatial expression patterns occur in response to spinal cord injury, suggesting different roles of these GTPases in the cellular sequelae of CNS injury.
Inhibition of P-glycoprotein-mediated docetaxel efflux sensitizes ovarian cancer cells to concomitant docetaxel and SN-38 exposure (2009)

The first-line treatment of ovarian cancer is based on cytoreductive surgery and the use of anticancer drugs. The main disadvantage in the usage of anticancer drugs is the wide capacity of cancer cells to acquire a resistance to chemotherapeutic agents and therefore new treatment strategies have to be developed and tested. In this study, the responses of seven ovarian carcinoma cell lines to docetaxel and a camptothecin derivative, SN-38, were evaluated. We further studied the expression of P-glycoprotein (P-gp), the best described mechanism of drug resistance, in these cells and the effect of treatment with a specific P-gp inhibitor (PGP-4008). Simultaneous treatment with docetaxel and SN-38 (docetaxel+SN-38) had an antagonistic growth effect that was not dependent on the administration schedule. Both drugs alone or in combination induced G2M cell cycle arrest. Docetaxel was a more potent inducer of apoptosis than SN-38, but simultaneous treatment with docetaxel+SN-38 decreased the proportion of apoptotic cells to the same level observed after exposure to SN-38 alone. SN-38 increased P-gp expression in all cell lines. PGP-4008 enhanced docetaxel-mediated growth inhibition and apoptosis, but it did not have an effect when used simultaneously with SN-38. When cells were treated with docetaxel, SN-38, and PGP-4008 simultaneously, the growth was inhibited more efficiently and the proportion of apoptotic cells was higher than that without PGP-4008. Thus, treatment of ovarian cancer cells with docetaxel+SN-38 may have antagonistic effects. The simultaneous administration of a P-gp inhibitor may prevent docetaxel efflux, thereby sensitizing cells to docetaxel and other chemotherapeutic agents.
Density of Natural Gases (1942)

Density data are reported on 16 saturated hydrocarbon vapors at pressuresranging from 1000 to 8220 lb. per sq. in. and at temperatures ranging from 35?to 250?F. These data have been used to extend the compressibility-factor chartfor natural gases up to 10,000 lb. per sq. in. The relatively large quantity ofhigh-boiling constituents present in high-pressure vapors in equilibrium withcrude oils makes it necessary to include in the analysis of the gas themolecular weight, density, and possibly boiling range of the heptanes andheavier fraction. Relationships have been presented by which the density ofgases may be obtained directly from the temperature, pressure, and gas gravityprovided the gases have a common source or are similar in composition. Introduction The densities of natural gases are necessary in many engineeringcomputations in petroleum production and utilization. Gas reserves, changes inreservoir pressure, gradients in gas wells, metering of gases, pipeline flow, and compression of gases are typical problems requiring the density of the gas.A decade ago, engineering computations used ideal gas laws with deviations upto 500 lb. per sq. in. Recent discoveries of pools having pressures up to 7500lb. per sq. in., and installation of pressure-maintenance and recycling plants, have increased the need for data on gas density at high pressures. Methods Of Computation The accepted method of computing the density or specific volume of naturalgases is the use of the ideal gas law corrected by a compressibility factor.The method proposed by Kay of correlating compressibility factors for gaseousmixtures on pseudo critical properties appears to be satisfactory for naturalgases. The methane-compressibility factor has been shown to deviatesystematically from the behavior of natural gases and a chart giving thesecorrected factors is available. A method of computing specific volume of gaseous mixtures from partial molalvolumes has been reported by Sage and Lacey. Complete data for the computationare not yet available for all hydrocarbon gases. Most of the reported data on gas densities have been in the single-phaseregion removed from the dew point or saturation condition. Since most gases inthe reservoir or while on contact with liquid during flow are saturated, thedetermination of densities under conditions of saturation is particularlyimportant. T.P. 1323
Secretion of biologically active porcine prophospholipase A<sub>2</sub> by <i>Saccharomyces cerevisiae</i> (1987)

The cDNA coding for porcine pancreatic prophospholipase A2 (proPLA) has been cloned and expressed in Saccharomyces cerevisiae. Expression and secretion of proPLA could only be obtained after fusing the proPLA to the prepro sequence of the yeast alpha-mating factor. Upon secretion, the fusion protein was cleaved by the KEX2 protease yielding a 140-amino-acid zymogen-like form of the phospholipase A2. This protein was purified in high yield by ion-exchange chromatography. Limited proteolysis with trypsin cleaved the 'zymogen' to yield active phospholipase A2, which was indistinguishable from the authentic porcine pancreatic enzyme. These results show that a protein with a disulphide bridge content as high as 7 per 124 amino acid residues can be correctly processed by the yeast secretory apparatus.
MEMS Sensor Technologies for Human Centred Applications in Healthcare, Physical Activities, Safety and Environmental Sensing: A Review on Research Activities in Italy (2015)

Over the past few decades the increased level of public awareness concerning healthcare, physical activities, safety and environmental sensing has created an emerging need for smart sensor technologies and monitoring devices able to sense, classify, and provide feedbacks to users’ health status and physical activities, as well as to evaluate environmental and safety conditions in a pervasive, accurate and reliable fashion. Monitoring and precisely quantifying users’ physical activity with inertial measurement unit-based devices, for instance, has also proven to be important in health management of patients affected by chronic diseases, e.g., Parkinson’s disease, many of which are becoming highly prevalent in Italy and in the Western world. This review paper will focus on MEMS sensor technologies developed in Italy in the last three years describing research achievements for healthcare and physical activity, safety and environmental sensing, in addition to smart systems integration. Innovative and smart integrated solutions for sensing devices, pursued and implemented in Italian research centres, will be highlighted, together with specific applications of such technologies. Finally, the paper will depict the future perspective of sensor technologies and corresponding exploitation opportunities, again with a specific focus on Italy.
