Corona Discharge Classification Based on UAV Data Acquisition (2017)

The Corona discharge represents one of the main concerns of the century in the field of electricity and powerline design, as it is both harmful for the environment as well as very costly to cover for the voltage losses on the transport. In this paper, we propose the design for a measurement and analysis platform for this phenomenon that can estimate the Corona discharge losses based on a video stream coming from an electro-optical sensor placed on board of an Unmanned Aerial Vehicle (UAV). After experimenting on a dataset generated from Corona discharge videos, our results suggest that of the supervised learning algorithms taken into consideration those based on Radial-Basis approaches are the most effective in classifying the information being fed to it. Before the classification task, we propose a starter set of filtering operation, composed of grayscale reduction, mean blurring and binary transformation.
Short-term load forecasting using an artificial neural network (1992)

An artificial neural network (ANN) method is applied to forecast the short-term load for a large power system. The load has two distinct patterns: weekday and weekend-day patterns. The weekend-day pattern includes Saturday, Sunday, and Monday loads. A nonlinear load model is proposed and several structures of an ANN for short-term load forecasting were tested. Inputs to the ANN are past loads and the output of the ANN is the load forecast for a given day. The network with one or two hidden layers was tested with various combinations of neurons, and results are compared in terms of forecasting error. The neural network, when grouped into different load patterns, gives a good load forecast.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
A Fast and Scalable Polyatomic Frank-Wolfe Algorithm for the LASSO (2022)

We propose a fast and scalable <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">polyatomic Frank-Wolfe (P-FW)</i> algorithm for the resolution of high-dimensional LASSO regression problems. This algorithm improves upon traditional Frank-Wolfe methods by considering generalized greedy steps with <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">polyatomic</i> ( <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">i.e.</i> linear combinations of multiple atoms) update directions, hence allowing for a more efficient exploration of the search space. To preserve sparsity of the intermediate iterates, we re-optimize the LASSO problem over the set of selected atoms at each iteration. For efficiency reasons, the accuracy of this re-optimization step is relatively low for early iterations and gradually increases with the iteration count. We provide convergence guarantees for our algorithm and validate it in simulated compressed sensing setups. Our experiments reveal that P-FW outperforms state-of-the-art methods in terms of runtime, both for FW methods and optimal first-order proximal gradient methods such as the <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Fast Iterative Soft-Thresholding Algorithm (FISTA)</i> .
Growth and Domain Structures of Ba2YCu3O7-y Single Crystals (1988)

Crystallographic and superconducting properties of single crystals of Ba 2 YCu 3 O 7- y grown by the flux method are studied. The single crystals were superconductors in as-grown atates. Domain observation by an interference microscope revealed that there were a few kinds of single crystals with a single domain and a few with several domains. A single-domain crystal had a tetragonal structure and a T c onset of ∼45 K while a multidomain crystal had an orthorhombic structure and a T c onset of ∼95 K. The latter crystal with no twins had several rectangular shape domains. It is thought that long one-dimensional chains of oxygens with a few 100 µm in length were realized in each domain of the crystal. The reason for the appearance of such domain structures is discussed.
Acute Myeloid Leukemia With Central Nervous System Involvement in Children: Experience From the French Protocol Analysis ELAM02 (2017)

Central nervous system (CNS) involvement at diagnosis of pediatric acute myeloid leukemia (AML) is not considered as an independent prognostic factor. This study describes the prognostic value of pediatric AML with CNS involvement at diagnosis. Pediatric patients were treated for de novo AML in the French multicenter trial ELAM02. Lumbar puncture was carried out in the first week, and the treatment was adapted to the CNS status. No patient received CNS radiotherapy. The patients were classified into 2 groups: CNS+ and CNS-. Of the 438 patients, 16% (n=70) had CNS involvement at diagnosis, and 29% showed clinical signs. The patients with CNS disease were younger (40% were below 2 y old), had a higher white blood cell count (median of 45 vs. 13 G/L), and had M4 and M5 morphologies. The complete remission rate was similar at 92.8% for CNS+ and 88.5% for CNS-. There was no significant difference between the CNS+ and the CNS- group in overall survival (76% and 71%, respectively) and event-free survival (57% and 52%, respectively). Regarding the occurrence of first relapse, the CNS+ group had a higher combined relapse rate of 26.1% compared with 10% for the CNS- group. The results indicate that CNS involvement at diagnosis of pediatric AML is not an independent prognostic factor. Triple intrathecal chemotherapy combined with high-dose intravenous cytarabine should be the first-line treatment for CNS disease.
Exploitation of digital filters to advance the single-phase T/4 delay PLL system (2016)

With the development of digital signal processing technologies, control and monitoring of power electronics conversion systems have been evolving to become fully digital. As the basic element in the design and analysis phases of digital controllers or filters, a number of unit delays (z <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> ) have been employed, e.g., in a cascaded structure. Practically, the number of unit delays is designed as an integer, which is related to the sampling frequency as well as the ac signal fundamental frequency (e.g., 50 Hz). More common, the sampling frequency is fixed during operation for simplicity and design. Hence, any disturbance in the ac signal will violate this design rule and it can become a major challenge for digital controllers. To deal with the above issue, this paper first exploits a virtual unit delay (z <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">v</sub> - <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> ) to emulate the variable sampling behavior in practical digital signal processors with a fixed sampling rate. This exploitation is demonstrated on a T/4 Delay Phase Locked Loop (PLL) system for a single-phase grid-connected inverter. The T/4 Delay PLL requires to cascade 50 unit delays when implemented (for a 50-Hz system with 10 kHz sampling frequency). Furthermore, digital frequency adaptive comb filters are adopted to enhance the performance of the T/4 Delay PLL when the grid suffers from harmonics. Experimental results have confirmed the effectiveness of the digital filters for advanced control systems.
The Viscosity Enhancement of Polyethers by Salts (1980)

The viscosity enhancement in low molecular weight poly-(ethylene oxide) and poly(propylene oxide) resulting from dissolution of LiClO4 was measured as a function of molecular weight and salt content. It is shown that on a log η vs. temperature plot, the viscosities for various salt contents yield lines of identical shape that can be superimposed by simple shifts along the temperature axis to yield a master curve for each molecular weight. Furthermore, by additional vertical shifting one can obtain a single master curve for all molecular weights and salt contents studied here, for each of the two families of polymers. Between about 3 and 13 mol % the increase in viscosity is attributable mainly to the increase in the glass transition temperature. Below that region another mechanism must be operative, since the glass transition rises only very slowly while the viscosity rises appreciably.
Cross-Linking Poly(lactic acid) Film Surface by Neutral Hyperthermal Hydrogen Molecule Bombardment (2015)

Constructing a dense cross-linking layer on a polymer film surface is a good way to improve the water resistance of poly(lactic acid) (PLA). However, conventional plasma treatments have failed to achieve the aim as a result of the unavoidable surface damage arising from the charged species caused by the uncontrolled high energy coming from colliding ions and electrons. In this work, we report a modified plasma method called hyperthermal hydrogen-induced cross-linking (HHIC) technology to construct a dense cross-linking layer on PLA film surfaces. This method produces energy-controlled neutral hyperthermal hydrogen, which selectively cleaves C-H bonds by molecule collision from the PLA film without breaking other bonds (e.g., C-C bonds in the polymer backbone), and results in subsequent cross-linking of the carbon radicals generated from the organic molecules. The formation of a dense cross-linking layer can serve as a barrier layer to significantly improve both the hydrophobicity and water vapor barrier property of the PLA film. Because of the advantage of selective cleavage of C-H bonds by HHIC treatment, the original physical properties (e.g., mechanical strength and light transmittance) of the PLA films are well-preserved.
TruffleC (2014)

This paper presents TruffleC, a C interpreter that allows the dynamic execution of C code on top of a Java Virtual Machine (JVM). Rather than producing a static build of a C application, TruffleC is a self-optimizing abstract syntax tree (AST) interpreter combined with a just-in-time (JIT) compiler. Our self-optimizing interpreter specializes the AST based on run-time feedback. AST specialization relies on optimistic assumptions and allows us to build inline caches for polymorphic function pointer calls, to profile runtime values and to potentially replace them with constants, or to speculatively remove code that was not executed yet.
GLUT1 production in cancer cells: a tragedy of the commons (2022)

The tragedy of the commons occurs when competition among individual members of a group leads to overexploitation of a shared resource to the detriment of the overall population. We hypothesize that cancer cells may engage in a tragedy of the commons when competing for a shared resource such as glucose. To formalize this notion, we create a game theoretic model of glucose uptake based on a cell's investment in transporters relative to that of its neighboring cells. We show that production of transporters per cell increases as the number of competing cells in a microenvironment increases and nutrient uptake per cell decreases. Furthermore, the greater the resource availability, the more intense the tragedy of the commons at the ESS. Based on our simulations, cancer cells produce 2.2-2.7 times more glucose transporters than would produce optimal fitness for all group members. A tragedy of the commons affords novel therapeutic strategies. By simulating GLUT1 inhibitor and glucose deprivation treatments, we demonstrate a synergistic combination with standard-of-care therapies, while also displaying the existence of a trade-off between competition among cancer cells and depression of their gain function. Assuming cancer cell transporter production is heritable, we then show the potential for a sucker's gambit therapy by exploiting this trade-off. By strategically changing environmental conditions, we can take advantage of cellular competition and gain function depression.
Hall cross size scaling and its application to measurements on nanometer-size iron particle arrays (2000)

Hall crosses were used to measure the magnetic properties of arrays of ferromagnetic, nanometer-scale iron particles. The arrays typically consist of several hundred particles of 9–20 nm in diameter. It is shown that the sensitivity of the measurements can be improved by matching the areas of the Hall cross and the array grown onto it by at least an order of magnitude. We predict that single particles of diameter as small as 10 nm can be measured if grown onto Hall crosses of appropriate size.
Knockdown and Mortality Comparisons Among Spinosad-, Imidacloprid-, and Methomyl-Containing Baits Against Susceptible <I>Musca domestica</I> (Diptera: Muscidae) Under Laboratory Conditions (2007)

The activity of spinosad, imidacloprid, and methomyl baits and technical actives were assessed against susceptible house flies, Musca domestica L. (Diptera: Muscidae). In a feeding assay, imidacloprid affected flies more rapidly than methomyl or spinosad, but spinosad was 2.7 times more potent than methomyl and 8 times more potent than imidacloprid. The profile of technical actives correlated with their respective fly bait formulations in laboratory assays. Although having the most rapid onset of activity in laboratory tests, up to 50% of flies remained alive after exposure to imidacloprid bait. In contrast, <5% of flies survived 24-h exposure to spinosad or methomyl baits. High temperature reduced the knockdown activity of imidacloprid bait and slowed the speed of kill for spinosad and methomyl baits over a 24-h exposure period. Spinosad and methomyl baits were also superior to imidacloprid when applied to the floors of environmentally controlled rooms at label recommended rates, providing good fly control for up to 21 d. The fact that a significant percentage of flies exposed to imidacloprid were rapidly knocked down but subsequently remained alive in all of the assays suggested that flies were recovering from initial exposure to this compound. Given its favorable safety profile, a high degree of initial and residual activity comparable with methomyl and lack of cross-resistance to other chemistries, spinosad bait may be a valuable component of house fly control programs to help control or delay the emergence of resistant populations.

Use of SS7 in D-AMPS-based PCS: orthodoxy vs. heterodoxy (1997)

D-AMPS, the digital version of the Advanced Mobile Phone System (AMPS), is among the key technologies for providing personal communications services (PCS). The bulk of signaling in D-AMPS-based PCS, as, in most modern telecommunication systems, is based on Signaling System No. 7 (SS7). SS7 is a general-purpose common channel signaling (CCS) system specified by the International Telecommunication Union Telecommunications Standardization Sector (ITU-T) and adapted to North American needs by the American National Standard Institute (ANSI). Besides the orthodox use for signaling, SS7 is used in D-AMPS-based PCS for operation, administration, maintenance, and provisioning (OAM&P) of the D-AMPS-based PCS network and for the short message service (SMS). This article reviews the use of SS7 in D-AMPS-based PCS. It motivates the need for a gradual return to orthodoxy where this use is confined to signaling. It also proposes alternatives to the current heterodox use. The alternatives the authors suggest are all rooted in orthodoxy.

Expression of the Osteoblast Differentiation Factor RUNX2 (Cbfa1/AML3/Pebp2αA) Is Inhibited by Tumor Necrosis Factor-α (2002)

The transcription factor RUNX2 (Cbfa1/AML3/Pebp2alphaA) is a critical regulator of osteoblast differentiation. We investigated the effect of the inflammatory cytokine tumor necrosis factor alpha (TNF) on the expression of RUNX2 because TNF is known to inhibit differentiation of osteoblasts from pluripotent progenitor cells. TNF treatment of fetal calvaria precursor cells or MC3T3-E1 clonal pre-osteoblastic cells caused a dose-dependent suppression of RUNX2 steady state mRNA as measured by reverse transcription-PCR. The IC(50) for TNF inhibition was 0.6 ng/ml. TNF suppression of RUNX2 mRNA was confirmed using Northern analysis. The effect of TNF was studied using isoform-specific primers that flanked unique regions of two major RUNX2 isoforms. TNF suppressed expression of the mRNA coding for the shorter MRIPV isoform by >90% while inhibiting expression of the mRNA for the longer MASNS isoform by 50%. RUNX2 nuclear content was evaluated by electrophoretic mobility shift assay using a rat osteocalcin promoter binding sequence as probe and by Western analysis. TNF reduced nuclear RUNX2 protein. Inhibition of new protein synthesis with cycloheximide failed to prevent TNF inhibition of RUNX2 mRNA, suggesting that a newly translated protein did not mediate the TNF effect. RUNX2 mRNA half-life was 1.8 h and reduced to 0.9 h by TNF. The effect of TNF on RUNX2 gene transcription was evaluated using a 0.6-kb RUNX2 promoter-luciferase reporter in MC3T3-E1 cells. TNF caused a dose-dependent inhibition of transcription to 50% of control values. The inhibitory effect of TNF was preserved with deletions to nucleotide -108 upstream of the translational start site; however, localization downstream of nucleotide -108 was obscured by loss of basal activity. Our results indicate that TNF regulates RUNX2 expression at multiple levels including destabilization of mRNA and suppression of transcription. The disproportionate inhibition of RUNX2 nuclear protein suggests that additional post-transcriptional mechanisms may be occurring. Suppression of RUNX2 by TNF may decrease osteoblast differentiation and inhibit bone formation in TNF excess states.
A study for the analysis of the program' efficacy with multimedia to enhance brain activity (2006)

The hamonious development of human brain has been an indigenous objective of each age. A variety of training programs related to the purpose have turned up at an educational market and a commercial market, as well. I'd like to indicate, however, that these training methods are somewhat prejudiced and have some elements, inherently, which are against the development of human brain for one's whole personality. Therefore, the most desirable brain training program is to induce it to respond to various stimuli, to educate for itself and to generate continuously, to create and strengthen an innumerous synapse among brain cells, so as to form a nero-network. In this study, I have used a brain training program with multimedia which have been produced for a specific purpose. With this method, by measuring directly the effectiveness of human brain development, I have analysed more objectively and more quantitatively.
Temperature Dependence of Molecular Tilt Angle and Rotatory Power in a Ferroelectric Liquid Crystal with Polarization Sign Reversal (1989)

Abstract The molecular tilt angle of the ferroelectric liquid crystal IS-2424 monotonously increases in the smectic C* phase with decreasing temperature from zero at the smectic A-smectic C* transition to about θ = 15°. It can be described by a critical exponent β = 0.26 ± 0.02. The temperature dependence of the tilt angle is definitely not proportional to the temperature dependence of the spontaneous polarization which shows a sign reversal.
