Anomaly Detection via One Class SVM for Protection of SCADA Systems (2013)

Funded by European Framework-7 (FP7), the CockpicCI project aims at developing intelligent risk detection, analysis and protection techniques for Critical Infrastructures (CI). In this paper, we describes our recent research on automated anomaly detection from central Supervisory Control and Data Acquisition (SCADA) systems and their related commands/measurements in the SCADA-field equipment communications. The work exploits the concept of one-class SVM (Support Vector Machines) and adaptively controls its decision parameter to detect unusual patterns from inputs and generate alarms for on-site engineers to further investigate. Experiments on simulation data sets from telecommunication networks illustrate that the proposed algorithm achieves high detection rates, providing excellent potential for further research and development towards practical tools for protection of SCADA systems.
Fluorescence excitation spectrum of the 1<i>A</i> <i>u</i> (<i>n</i>π) ←1<i>A</i> <i>g</i> (0–0) band of oxalyl fluoride in a pulsed supersonic free jet (1979)

Oxalyl fluoride has been cooled to a rotational temperature of 0.17 K in a pulsed, supersonic jet. Individual rotational lines in the (0–0) band of the fluorescence excitation spectrum have been observed and assigned, and the rotational constants for both the 1Ag and 1Au states have been deduced. The pulsed nozzle used in these experiments can be operated with a far larger orifice diameter and at lower pressures than typically used in continuously operated nozzles, allowing greater cooling and higher jet densities while maintaining a low level of condensation.
Epitaxial growth of <i>p</i>-type ZnMgSSe (1994)

N-doped p-type ZnMgSSe was grown by molecular beam epitaxy. Nitrogen was induced by electron cyclotron resonance plasma. The maximum net acceptor concentration (NA−ND) and the activation energy of the nitrogen acceptor (EN) depend on the band-gap energy of ZnMgSSe. With increasing band-gap energy, the maximum NA-ND is decreased and EN is increased. The maximum NA-ND and the EN of ZnMgSSe with a band-gap energy of 3.05 eV at 77 K are 2.5×1016 cm−3 and 140 meV, respectively.
New and Continuing Measurement Challenges for 5G mmWave and Beamforming Technologies (2019)

As the wireless industry rushes forward with the development and deployment of 5G radio technology, there are still fundamental questions, both in radio design and manufacturing, especially in the millimeter wave (mmWave) FR2 band. With this headlong rush, 3GPP has made some tentative steps forward in over-the-air test and measurement of the various radio metrics, but many of the original issues remain and new ones have come to light. This paper will attempt to cover the progress to date and a number of the outstanding issues still to be resolved.
Enteric P2X receptors as potential targets for drug treatment of the irritable bowel syndrome (2004)

The irritable bowel syndrome (IBS) is a gastrointestinal motility disorder affecting millions of patients. IBS symptoms include diarrhea, constipation and pain. The etiology of IBS is due partly to changes in the function of nerves supplying the gastrointestinal tract, immune system activation and to psychological factors. P2X receptors are multimeric ATP-gated cation channels expressed by neuronal and non-neuronal cells. Sensory nerve endings in the gastrointestinal tract express P2X receptors. ATP released from gastrointestinal cells activates P2X receptors on sensory nerve endings to stimulate motor reflexes and to transmit nociceptive signals. Antagonists acting at P2X receptors on sensory nerves could attenuate abdominal pain in IBS patients. Primary afferent neurons intrinsic to the gut, and enteric motor- and interneurons express P2X receptors. These neurons participate in motor reflexes. Agonists acting at enteric P2X receptors may enhance gastrointestinal propulsion and secretion, and these drugs could be useful for treating constipation-predominant IBS. Antagonists acting at enteric P2X receptors would decrease propulsion and secretion and they might be useful for treating diarrhea-predominant IBS. Current knowledge of P2X receptor distribution and function in the gut of laboratory animals provides a rational basis for further exploration of the therapeutic potential for drugs acting at P2X receptors in IBS patients. However, more information about P2X receptor distribution and function in the human gastrointestinal tract is needed. Data on the distribution and function of P2X receptors on gastrointestinal immune cells would also provide insights into the therapeutic potential of P2X receptor agents in IBS.
Organization and environmental regulation of the Pseudomonas syringae pv. syringae 61 hrp cluster (1992)

The ability of Pseudomonas syringae pv. syringae 61 to elicit the hypersensitive response in nonhost plant species has been linked to a cluster of hrp/hrm genes whose expression appears to be environmentally regulated. To understand the genetic organization of this hrp/hrm gene cluster and its expression during the interaction with nonhost plant species better, we constructed a set of chromosomal hrp-uidA fusions in P. syringae pv. syringae 61 by Tn5-gusA1 mutagenesis of the cloned hrp/hrm gene cluster and transferred them into the genome by marker exchange mutagenesis. Complementation analysis employing plasmid-borne Tn5-gusA1 insertions and previously characterized chromosomal TnphoA mutations defined at least eight apparent transcriptional units within the hrp/hrm cluster, several of which were multicistronic. The expression of hrp-uidA fusions in seven of these apparent hrp transcriptional units increased following inoculation into tobacco leaves. Enhanced expression from a representative fusion was detected 1 h after inoculation of tobacco leaves. The induction observed in planta was similar to the levels detected following culture of the bacteria in minimal-salts medium: irrespective of the carbon source. Complex amino acid sources, such as peptone, repressed the expression of P. syringae pv. syringae 61 hrp genes at levels exceeding 0.028%. The results indicate that enhanced expression of hrp genes occurs early in the interaction with nonhost plant species in an apparent response to altered nutritional conditions.
Stack Cache Memory for Block-Structured Programs (1994)

The architecture of a cache memory is presented, aimed at reducing the memory bandwidth requirements of programs written in block-structured, high-level languages. At any given time, the cache contains two portions of the stack area of the running program, corresponding to the global and the local activation records. With respect to traditional cache architectures, the proposed architecture is characterized by increased performance and a reduced complexity of the logic for cache space addressing and management. These results have been obtained by controlling the cache activity at the software level to take advantage of the stack paradigm.
Preparation and Adsorption Properties for Thiophene of Nanostructured W<sub>2</sub>C on Ultrahigh-Surface-Area Carbon Materials (2003)

Nanostructured tungsten carbides on ultrahigh-surface-area carbon (>3000 m2/g), a kind of novel carbon material with uniform pore distribution, have been prepared by carbothermal reduction, carbothermal hydrogen reduction, and metal-promoted carbothermal hydrogen reduction under mild conditions. The resulting carbides have been characterized by X-ray diffraction, transmission electron microscopy, temperature-programmed reduction−mass spectroscopy, and N2 physico-sorption. The adsorption properties of thiophene on nanostructured tungsten carbides on ultrahigh-surface-area carbon were also investigated in a fixed-bed reactor. The results show that nanostructured W2C particles of about 10 nm on ultrahigh-surface-area carbon material can be synthesized by carbothermal reduction and carbothermal hydrogen reduction at 850 °C. Nanostructured W2C has also been obtained by metal Ni-promoted carbothermal hydrogen reduction even at 650 °C. The results also show that carbothermal hydrogen reduction can form tungsten carbides under relatively mild conditions compared to carbothermal reduction, and addition of Ni further decreases formation temperatures of tungsten carbides. Tungsten carbides formation involves the sequence WO3 → WOx (0 < x < 3) → W → W2C → WC. The results on adsorption show that W2C/HSAC has superior properties for removal of sulfur-containing compounds in fuel oil and the adsorption properties can be recovered after H2 reduction at 800 °C. The adsorption capacity of the samples on thiophene is in the following order: W2C/HSAC > W/HSAC > WC/HSAC ≫ HSAC. Nanostructured W2C/HSAC may be of great potential in ultra-deep removal of sulfur-containing compounds in fuel oil.

Stereochemistry of the epoxydon group antibiotic G7063-2 isolated from a Streptomyces species HPL Y-25711. (1984)

The absolute configuration of the ring system of the antibiotic G7063-2 has been established as being the same as that reported for terreic acid, based on circular dichroism data. During structure elucidation experiments, reaction with ethereal diazomethane gave an adduct whose structure is proposed.
Tightly-Coupled INS, GPS, and Imaging Sensors for Precision Geolocation (2008)

Abstract : Recent technological advances have significantly improved the capabilities of micro-air vehicles (MAV). This is evidenced by their expanding use by government, police, and military forces. A MAV can provide a real-time surveillance capability to even the smallest units, which provides commanders with a significant advantage. This capability is a result of the availability of miniaturized autopilot systems which typically combine inertial, pitot-static, and GPS sensors into a feedback flight-control system. While these autopilots can provide an autonomous flight capability, they have some limitations which impact their operational effectiveness. One of the primary issues is poor image geolocation performance, which limits the use of these systems for direct measurements of target locations. This poor geolocation performance is primarily a consequence of the relatively large attitude errors characteristic of low-performance inertial sensors. In previous efforts, we have developed a tightly-coupled image-aided inertial navigation system to operate in areas not serviced by GPS. This system extracts navigation information by automatically detecting and tracking stationary optical features of opportunity in the environment. One characteristic of this system is vastly reduced attitude errors, even with consumer-grade inertial sensors. In this paper, the benefits of incorporating image-based navigation techniques with inertial and GPS measurements is explored. After properly integrating GPS with the image-aided inertial architecture, the system is tested using a combination of Monte-Carlo simulation and flight test data. The flight test data was flown over Edwards AFB using representative hardware. The experimental results are compared with validated truth data.
The Use of Ethanol to Monitor Fluid Absorption during Transurethral Resection of the Prostate (1999)

Ethanol monitoring is a method for assessing fluid absorption during transurethral resection of the prostate. The method is based on the principle that absorption can be measured by expired-breath tests provided that an irrigating fluid containing ethanol 1% is used. A nomogram for transformation of the ethanol data into meaningful indices of fluid absorption, such as the volume of irrigant absorbed and the degree of hyponatraemia, has been approved for routine use within the European Union. To make a correct interpretation, however, one must learn how to distinguish the pattern of breath ethanol changes typical of absorption of fluid directly into the blood from the pattern associated with the rare intraoperative events in which fluid is deposited in a pool in the retro- or intraperitoneal space. The ethanol method is well documented, but it is still sparsely used outside Scandinavia, due to its lack of a patent and differing opinions concerning the need for measuring fluid absorption.
Hearing Loss, Quality of Life, and Academic Problems in Long-term Neuroblastoma Survivors: A Report From the Children's Oncology Group (2007)

We found evidence that long-term neuroblastoma survivors, especially those with hearing loss, are at elevated risk for academic learning problems and psychosocial difficulties. We also found strong concordance between parent-reported learning problems in the child and indications of distress in the child's self-reported quality of life.
Performance comparison between ATM LAN emulation, classical IP over ATM, and native ATM in a multi-platform multi-operating system environment (2002)

The question of how best to integrate asynchronous transfer mode (ATM) technology into the local area network (LAN) infrastructure and how well ATM will interoperate with existing LAN technologies is critical to the success of the ATM. We present the results of a study which deals with both the implementation issues and a performance comparison between three key mechanisms available for implementing ATM in the LAN environment today. The three mechanisms compared are the LAN emulation (LANE), classical IP over ATM (CLIP), and native ATM (NATM). The results of our performance comparison are based on measurements taken on a fully operational multi-switch ATM infrastructure capable of supporting multiple CLIP, LANE, and native ATM sub-nets. Our performance comparisons characterize both high volume data transfer capabilities and transaction processing (i.e., query and response) capabilities of various computing platforms while interconnected via LANE, CLIP, and native ATM. Our performance results indicate that the highest throughputs are achieved under native ATM and classical IP, followed by LAN emulation, respectively.
The Glycosyltransferase Domain of Penicillin-Binding Protein 2a from <i>Streptococcus pneumoniae</i> Catalyzes the Polymerization of Murein Glycan Chains (2003)

The bacterial peptidoglycan consists of glycan chains of repeating beta-1,4-linked N-acetylglucosaminyl-N-acetylmuramyl units cross-linked through short peptide chains. The polymerization of the glycans, or glycosyltransfer (GT), and transpeptidation (TP) are catalyzed by bifunctional penicillin-binding proteins (PBPs). The beta-lactam antibiotics inhibit the TP reaction, but their widespread use led to the development of drug resistance in pathogenic bacteria. In this context, the GT catalytic domain represents a potential target in the antibacterial fight. In this work, the in vitro polymerization of glycan chains by the extracellular region of recombinant Streptococcus pneumoniae PBP2a, namely, PBP2a* (the asterisk indicates the soluble form of the protein) is presented. Dansylated lipid II was used as the substrate, and the kinetic parameters K(m) and k(cat)/K(m) were measured at 40.6 micro M (+/- 15.5) and 1 x 10(-3) M(-1) s(-1), respectively. The GT reaction catalyzed by PBP2a* was inhibited by moenomycin and vancomycin. Furthermore, the sequence between Lys 78 and Ser 156 is required for enzymatic activity, whereas it is dispensable for lipid II binding. In addition, we confirmed that this region of the protein is also involved in membrane interaction, independently of the transmembrane anchor. The characterization of the catalytically active GT domain of S. pneumoniae PBP2a may contribute to the development of new inhibitors, which are urgently needed to renew the antibiotic arsenal.
A review of fault management in WDM mesh networks: basic concepts and research challenges (2004)

The article first presents a broad overview of the fault management mechanisms involved in deploying a survivable optical mesh network which employs optical crossconnects. We review various protection and restoration schemes, primary and back-up route computation methods, shareability optimization, and dynamic restoration. We then describe different parameters that can measure the quality of service provided by a WDM mesh network to upper protocol layers (e.g., IP network backbones, ATM network backbones, leased lines, virtual private networks), such as service availability, service reliability, restoration time, and service restorability. We review these concepts, the factors that affect them, and how to improve them. In particular, we present a framework for cost-effective availability-aware connection provisioning to provide differentiated services in WDM mesh networks. Through the framework, the more realistic scenario of multiple near-simultaneous failures can be handled. In addition, the emerging problem of protecting low-speed connections of different bandwidth granularities is also reviewed.
Life and Thought in the Greek and Roman World (1942)

This book is a comprehensive survey of Greek and Roman life. The authors defend their decision to treat Greek and Roman life as a single subject by arguing that, from a broad perspective, the similarities between the two cultures are more evident than the differences.
Resistance to myocardial ischemia in five rat strains: is there a genetic component of cardioprotection? (2000)

There is a need to develop new and more consistent animal models of cardioprotection. Traditionally, outbred dogs, rabbits, and rats have been studied. We determined resistance to ischemia in isolated hearts from inbred strains of rats. Hearts from inbred rats: SS/Mcw (Dahl S, Dahl salt-sensitive), DA/Hsd (Dark Agouti), LEW/Hsd (Lewis), and BN/SsN/Mcw (Brown Norway); and from an outbred rat: Hsd:WIST (Wistar) were subjected to 27 min of global, no-flow ischemia, followed by 3 h of reperfusion. Infarct size in the Brown Norway rat was 2.5 times less than that observed in the Dahl S rat, with the Dark Agouti, Lewis, and Wistar rats intermediate in response. Hearts from Brown Norway rats were also most resistant to ischemia in terms of postischemic enzyme leakage and contractile and vascular function compared with other strains. The average polymorphism rate between strains revealed that such strains were genetically diverse. This study demonstrates strain differences in resistance to myocardial ischemia, suggesting these rats could be used to study a genetic and/or environmental basis for these differences and to provide new animal models for the physiological study of cardioprotection.
Universal calibration in GPC (1972)

Abstract The M [η]‐elution volume calibration curve for gel‐permeation chromatography (GPC) is based on the implicit assumption that the hydrodynamic volume of a solvated polymer species in the GPC columns is that which pertains at infinite dilution. This is not true of highly solvated high molecular weight fractions and results in apparent failure of this calibration in some instances. A model is presented to estimate hydrodynamic volumes of polymers at finite concentrations. The parameters required are polymer concentration, molecular weight, amorphous density, and the Mark‐Houwink constants for the particular polymer–solvent combination. The calculated log (hydrodynamic volume)–elution volume relation provides a universal GPC calibration. The model accounts for the occasional shortcomings of the infinite dilution calibration and is essentially equivalent to it in noncritical cases. The use of the proposed calibration method is illustrated.
Glutamine metabolism in lymphocytes of the rat (1983)

The metabolism of glutamine in resting and concanavalin-A-stimulated lymphocytes was investigated. In incubated lymphocytes isolated from rat mesenteric lymph nodes, the rates of oxygen and glutamine utilization and that of aspartate production were approximately linear with respect to time for 60 min, and the concentrations of adenine nucleotides plus the ATP/ADP or ATP/AMP concentration ratios remained approximately constant for 90 min. The major end products of glutamine metabolism were glutamate, aspartate and ammonia: the carbon from glutamine may contribute about 30% to respiration. When both glucose and glutamine were presented to the cells, the rates of utilization of both substances increased. Evidence was obtained that the stimulation of glycolysis by glutamine could be due, in part, to an activation of 6-phosphofructokinase. Starvation of the donor animal increased the rate of glutamine utilization. The phosphoenolpyruvate carboxykinase inhibitor mercaptopicolinate decreased the rate of glutamine utilization by 28%; the rates of accumulation of glutamate and ammonia were decreased, whereas those of lactate, aspartate and malate were increased. The mitogen concanavalin A increased the rate of glutamine utilization (by about 51%). The rate of [3H]thymidine incorporation into DNA caused by concanavalin A in cultured lymphocytes was very low in the absence of glutamine; it was increased about 4-fold at 1 microM-glutamine and was maximal at 0.3 mM-glutamine; neither other amino acids nor ammonia could replace glutamine.
Mitochondrial Autophagy Is an HIF-1-dependent Adaptive Metabolic Response to Hypoxia (2008)

Autophagy is a process by which cytoplasmic organelles can be catabolized either to remove defective structures or as a means of providing macromolecules for energy generation under conditions of nutrient starvation. In this study we demonstrate that mitochondrial autophagy is induced by hypoxia, that this process requires the hypoxia-dependent factor-1-dependent expression of BNIP3 and the constitutive expression of Beclin-1 and Atg5, and that in cells subjected to prolonged hypoxia, mitochondrial autophagy is an adaptive metabolic response which is necessary to prevent increased levels of reactive oxygen species and cell death.
Design and Development of a Run-Time Monitor for Multi-Core Architectures in Cloud Computing (2011)

Cloud computing is a new information technology trend that moves computing and data away from desktops and portable PCs into large data centers. The basic principle of cloud computing is to deliver applications as services over the Internet as well as infrastructure. A cloud is a type of parallel and distributed system consisting of a collection of inter-connected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources. The large-scale distributed applications on a cloud require adaptive service-based software, which has the capability of monitoring system status changes, analyzing the monitored information, and adapting its service configuration while considering tradeoffs among multiple QoS features simultaneously. In this paper, we design and develop a Run-Time Monitor (RTM) which is a system software to monitor the application behavior at run-time, analyze the collected information, and optimize cloud computing resources for multi-core architectures. RTM monitors application software through library instrumentation as well as underlying hardware through a performance counter optimizing its computing configuration based on the analyzed data.
