Traffic monitoring and analysis for the optimization of a 3G network (2006)

Recent years have recorded a surge of research activities on IP traffic monitoring, enabled by the availability of monitoring hardware and large-scale storage at accessible costs. More recently, passive monitoring has been applied to operational 3G networks. The passive observation of network traffic, coupled with advanced traffic-analysis methods, can be a powerful and cost-effective means to infer the network status and localize points of performance degradation without requiring complete access to all network elements. Furthermore, the availability of high-quality traces can be exploited to predict the load of the network under hypothetical conditions, variations of the actual network configuration at the capturing time. Both approaches can be useful for some engineering and reoptimization tasks that are commonly encountered in the lifetime of an operational 3G network. In abstract terms, the availability of high-quality traces can greatly empower the measurement-based optimization cycle, with human experts in the loop, thus driving an already operational 3G network toward improved performances. In this article we discuss the contribution that traffic monitoring and analysis (TMA) can provide to the optimization of an operational 3G network
Reliability and Validity Testing of the Physical Resilience Measure (2011)

Future use of the Physical Resilience Scale should consider adding more challenging items to better differentiate those particularly high in physical resilience.
OmcB, ac-Type Polyheme Cytochrome, Involved in Fe(III) Reduction inGeobacter sulfurreducens (2003)

Microorganisms in the family Geobacteraceae are the predominant Fe(III)-reducing microorganisms in a variety of subsurface environments in which Fe(III) reduction is an important process, but little is known about the mechanisms for electron transport to Fe(III) in these organisms. The Geobacter sulfurreducens genome was found to contain a 10-kb chromosomal duplication consisting of two tandem three-gene clusters. The last genes of the two clusters, designated omcB and omcC, encode putative outer membrane polyheme c-type cytochromes which are 79% identical. The role of the omcB and omcC genes in Fe(III) reduction in G. sulfurreducens was investigated. OmcB and OmcC were both expressed during growth with acetate as the electron donor and either fumarate or Fe(III) as the electron acceptor. OmcB was ca. twofold more abundant under both conditions. Disrupting omcB or omcC by gene replacement had no impact on growth with fumarate. However, the OmcB-deficient mutant was greatly impaired in its ability to reduce Fe(III) both in cell suspensions and under growth conditions. In contrast, the ability of the OmcC-deficient mutant to reduce Fe(III) was similar to that of the wild type. When omcB was reintroduced into the OmcB-deficient mutant, the capacity for Fe(III) reduction was restored in proportion to the level of OmcB production. These results indicate that OmcB, but not OmcC, has a major role in electron transport to Fe(III) and suggest that electron transport to the outer membrane is an important feature in Fe(III) reduction in this organism.
Prospects of VLSI on robot sensors (2003)

It is shown how sensor research for robotics has evolved from a mechanical discipline towards the area of artificial intelligence. VLSI plays a key role in this development, where the boundaries between sensing and signal processing are gradually fading. The development of micromachining anticipates a logical follow-up of the integration of sensing and signal conditioning: the integration of the excitation of actuation. Where proprioceptive sensing still needs accurate, metric information, exteroceptive sensing is increasingly realized by sensors designed mainly for characteristic structural information such as images and signatures. Silicon remains the most important building material for smart sensors and actuators. However, there is an increasing interest in other materials that can be used in combination with silicon, offering new possibilities for VLSI sensors and actuators. Piezoelectric polymers have already proved to be suitable materials for this purpose.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Novel Task Allocation Method for Emergency Events under Delay-Cost Tradeoff (2022)

With the emergence of three new paradigms, namely the Internet of Things (IoT), cloud/edge computing and mobile social networks; Mobile Crowd Sensing (MCS) has emerged as a potential approach for data collecting in numerous applications, such as traffic management, infotainment, disaster management or public safety. MCS mechanisms are receiving a lot of attention, both from research and development areas, showing their impact and benefit. But their optimization is still under development, mainly due to the large number of involved parameters. A major field within MCS relates to crowd management for emergency situations, where the management and optimization mechanisms become crucial to local authorities. To tackle this problem, in this work, we propose an MCS hybrid worker selection scheme that operated various modes depending on the delay-cost requirements. Our scheme exploits the user behavior to achieve an optimal bi-objective for any delay-cost requirement. We use simulations to evaluate the performance of our proposal, and we show the optimal and different sub-optimal solutions that can match the delay-cost requirements.
Blood lactate changes during exercise at high altitude (1987)

Blood lactate concentrations were measured in 18 normal subjects at the end of an exercise test designed to maintain heart rate at 85% of maximum for 15 minutes. Blood lactate concentrations were reduced at high altitude (4846 m) and correlated positively with basal pH and negatively with basal Pa,O2 levels. Blood lactate concentrations tended to be lower in those subjects on acetazolamide but were not correlated with the severity of acute mountain sickness or with the workload of the exercise test. We conclude that the pH changes are probably the most significant factor in reducing lactate concentrations.
Three unusual supernova remnants (1979)

The radio sources G326.3 – 1.8, G348.5 + 0.1 and G348.7 + 0.3 have been observed with a resolution of 0.8 arcmin using the 1.4-GHz Fleurs synthesis telescope and 2.2 arcmin at 14.7 GHz with the Parkes 64-m telescope. These observations, in combination with lower-resolution measurements over a wide frequency range, confirm that each source is a supernova remnant in our galaxy. G348.5 + 0.1 (CTB 37A) and G348.7 + 0.3 (CTB 37B) are of similar size and brightness and, in projection, are separated by little more than their own diameter. ‘Emerging’ from the shell of G348.5 + 0.1 there is a remarkable ‘jet’ – a feature not previously found among supernova remnants. G326.3 – 1.8 (MSH 15-56) is also unusual in that it possesses not only a shell typical of most supernova remnants but also a flat-spectrum central core which shows marked similarities to the Crab nebula.
Evidence that diphtheria toxin and modeccin enter the cytosol from different vesicular compartments. (1984)

Inhibition of protein synthesis in Vero cells was measured at different periods of time after treatment with diphtheria toxin and the related plant toxin modeccin. Diphtheria toxin acted much more rapidly than modeccin. Cells were protected against both toxins with antiserum as well as with agents like NH4Cl, procaine, and the ionophores monensin, FCCP, and CCCP, which increase the pH of intracellular vesicles. Antiserum, which is supposed to inactivate toxin only at the cell surface, protected only when it was added within a short period of time after modeccin. Compounds that increase the pH of intracellular vesicles, protected even when added after 2 h, indicating that modeccin remains inside vesicles for a considerable period of time before it enters the cytosol. After addition of diphtheria toxin to the cells, compounds that increase the pH of intracellular vesicles protected only approximately to the same extent as antitoxin. This indicates that after endocytosis diphtheria toxin rapidly enters the cytosol. At 20 degrees C, the cells were more strongly protected against modeccin than against diphtheria toxin. The residual toxic effect of diphtheria toxin at 20 degrees C could be blocked with NH4Cl whereas this was not the case with modeccin. This indicates that at 20 degrees C the uptake of diphtheria toxin occurs by the normal route, whereas the uptake of modeccin occurs by a less efficient route than that dominating at 37 degrees C. The results indicate that after endocytosis diphtheria toxin rapidly enters the cytosol from early endosomes with low pH (receptosomes). Modeccin enters the cytosol much more slowly, possibly after fusion of the endocytic vesicles with another compartment.
Polymorphism of ?2-glycoprotein I at codons 306 and 316 in patients with systemic lupus erythematosus and antiphospholipid syndrome (1999)

The prevalence of mutations in the fifth domain of beta2GPI in these patients with SLE and/or APS were similar to those previously reported for the general population. Heterozygosity for either mutation does not influence the incidence of aPL, but in patients with SLE, the mutation at exon 8 may predispose to thrombosis as an independent factor.

Direct Synthesis of Carbon-Doped TiO2–Bronze Nanowires as Anode Materials for High Performance Lithium-Ion Batteries (2015)

Carbon-doped TiO2-bronze nanowires were synthesized via a facile doping mechanism and were exploited as active material for Li-ion batteries. We demonstrate that both the wire geometry and the presence of carbon doping contribute to the high electrochemical performance of these materials. Direct carbon doping for example reduces the Li-ion diffusion length and improves the electrical conductivity of the wires, as demonstrated by cycling experiments, which evidenced remarkably higher capacities and superior rate capability over the undoped nanowires. The as-prepared carbon-doped nanowires, evaluated in lithium half-cells, exhibited lithium storage capacity of ∼306 mA h g(-1) (91% of the theoretical capacity) at the current rate of 0.1C as well as excellent discharge capacity of ∼160 mAh g(-1) even at the current rate of 10 C after 1000 charge/discharge cycles.
Analysis of Hybrid Translinear Circuit and Its Application (2006)

A hybrid translinear (TL) circuit constituted by two kinds of transistors, bipolar and CMOS transistors, was proposed to control its quiescent current. And a new method was introduced to analyze the hybrid TL circuit, which converted it into an uniform equivalent bipolar TL circuit. It simplified its analysis and design. This hybrid TL circuit is applied to the output stage of a class AB amplifier. The simulation results in 1.5μm BCD (Bipolar-CMOS-DMOS) technology were consistent with expectations well.
Quantum ensembles of quantum classifiers (2017)

Quantum machine learning witnesses an increasing amount of quantum algorithms for data-driven decision making, a problem with potential applications ranging from automated image recognition to medical diagnosis. Many of those algorithms are implementations of quantum classifiers, or models for the classification of data inputs with a quantum computer. Following the success of collective decision making with ensembles in classical machine learning, this paper introduces the concept of quantum ensembles of quantum classifiers. Creating the ensemble corresponds to a state preparation routine, after which the quantum classifiers are evaluated in parallel and their combined decision is accessed by a single-qubit measurement. This framework naturally allows for exponentially large ensembles in which -- similar to Bayesian learning -- the individual classifiers do not have to be trained. As an example, we analyse an exponentially large quantum ensemble in which each classifier is weighed according to its performance in classifying the training data, leading to new results for quantum as well as classical machine learning.
LYSINE MEDIATED ASSEMBLY OF GOLD NANOPARTICLES (2007)

This paper reports the data of an investigation of the gold nanoparticles assembly mediated by organic molecules, such as lysine. Gold nanoparticles were synthesized in citrate aqueous solution and characterized by UV-Vis spectroscopy and a strong absorption band at 528 nm is found for surface plasmon resonance. Transmission electron microscopy (TEM) images indicate a mean gold nanoparticle size of about 14 nm. The aqueous colloidal gold solution is stable in time, indicating a good electrostatic stabilization of gold nanoparticles through the adsorbed monolayer of citrate anions on nanoparticle surface. The interaction between the citrate capped gold nanoparticles in aqueous solution and lysine was investigated monitoring their UV-Vis spectra. At a certain lysine/gold ratio a new, large absorption band appears between 600 and 700 nm, which increases in time, while the color of the colloidal gold solution changes from red to blue. The 528 nm band decreases, as a consequence of the assembly formation of gold nanoparticles mediated by lysine. The nanostructure of the lysine mediated assembly of gold particles is analyzed by TEM and atomic force microscopy (AFM). The TEM and AFM images evidence the assembly of gold nanoparticles, where particles are not in direct physical contact. This effect could be explained primarily through the zwitterion-type electrostatic interactions between the charged amine and acid groups of the lysine molecules adsorbed and bound to different gold nanoparticles. These findings provide new insights into the precise control of interfacial interactions between organic molecules anchored on gold nanoparticles.
From National to International Experience – The European Crime Prevention Network (EUCPN) (2010)

The European Crime Prevention Network (EUCPN) was set up in May 2001. It’s idea is to promote more effective crime prevention activity and best practices in the Member States across the EU, and to provide a means for sharing good practice in crime prevention experience and knowledge gained by Member States. As a framework, EUCPN uses various means to exchange information and maintains close contacts with all relevant stakeholders such as crime prevention bodies, authorities and civil society.
Hydrodynamics of a Novel Biomass Autothermal Fast Pyrolysis Reactor: Flow Pattern and Pressure Drop (2008)

Abstract A novel biomass, autothermal, fast pyrolysis reactor with a draft tube and an internal dipleg dividing the reactor into two interconnected beds is proposed. This internally interconnected fluidized beds (IIFB) reactor is designed to produce high‐quality bio‐oil using catalysts. Meanwhile, the pyrolysis by‐products, i.e., char, coke and non‐condensable gases, are expected to burn in the combustion bed to provide the heat for the pyrolysis. On the other hand, the catalysts can be regenerated simultaneously. In this study, experiments on the hydrodynamics of a cold model IIFB reactor are reported. Geldart group B and D sand particles were used as the bed materials. The effects of spouting and fluidizing gas velocities, particle size, static bed height and the total pressure loss coefficient of the pyrolysis bed exit, on the flow patterns and pressure drops of the two interconnected beds are studied. Six distinct flow patterns, i.e., fixed bed (F), periodic spouted/bubbling bed (PS/B), spouted bed with aeration (SA), spout‐fluidized bed (SF), spout‐fluidized bed with slugging (SFS) and spouted bed with backward jet (SBJ) are identified. The investigations on the pressure drops of the two beds show that both of them are seen to increase at first (mainly in the F flow pattern), then to decrease (mainly in the PS/B and SA flow patterns) and finally to increase again (mainly in the SA and SF flow patterns), with the increase of the spouting gas velocity. It is observed that a larger particle size and lower static bed height lead to lower pressure drops of the two beds.
Regional Mapping of Karst Terrains in Order to Avoid Potential Environmental Problems (1996)

Abstract The Oklahoma Geological Survey will prepare a map of the State at a scale of 1:500,000 to show karst terrains and associated environmental problems in Oklahoma. Surface and near-surface carbonates (limestone and dolomite) comprise about 6% of the surface area of the State, whereas sulphates (gypsum and anhydrite) comprise about 5% of the State. Areas of carbonates and sulphates will be differentiated and mapped separately as two zones: in zone 1 they are 0-30 m deep. Areas underlain by bedded salt (halite) within 300 m of the surface comprise 14.6% of the State, and they will be mapped as zone 3.
Mechanism of phenolic activation of Agrobacterium virulence genes: development of a specific inhibitor of bacterial sensor/response systems. (1991)

The aglycone of the dihydrodiconiferyl alcohol glycosides, a series of phenolic growth factors able to substitute for some of the hormone requirements of tobacco cell division, are also potent inducers of virulence gene expression in Agrobacterium tumefaciens. However, these factors do not conform to the previously established structural requirements necessary for vir expression. Systematic evaluation of the structural requirements of these inducers has led to a model detailing the role of the phenolics in induction. With this model, a specific inhibitor of vir induction has been developed. This inhibitor does not affect the induction of other genes on the Ti plasmid but irreversibly blocks vir expression. The inhibitor has been used to show that the inducing phenolics must be constantly present to maintain expression of the vir regulon.
Comparative Nutritional Value of Eastern Gamagrass and Alfalfa Hay for Dairy Cows (1985)

Eastern gamagrass hay (Tripsacum dactyloides) and alfalfa hay (Medicago saliva) were compared. Digestibility of first and second cuttings of each was determined using 12 mature wethers in a replicated 4 4 Latin-square design. Apparent digestibilities of dry matter, crude protein, acid detergent fiber, and neutral detergent fiber for first and second cutting alfalfa and first and second cutting gamagrass hay were: 53.6, 68.2, 41.4, 48.7; 54.7, 70.4, 38.3, 41.1; 57,3, 57.7, 60.0, 65.3; 52.3, 50.2, 54.1, 59.1%. Eastern gamagrass was about equal to alfalfa hay in digestibility. In a feeding trial, hays were compared as energy sources for lactating dairy cows with protein intake adjusted by feeding grain mixtures containing 12, 15, or 18% crude protein with alfalfa, first cutting gamagrass, and second cutting gamagrass hay, respectively. Intake of protein and dry matter of hay averaged 2.09 and 9.85 kg/d for alfalfa and 1.27 and 8.97 kg/d for gamagrass. Milk yield of cows fed alfalfa was higher than that of cows fed gamagrass (24.1 vs. 22.9 kg/d). Milk fat tests and weight changes were similar. Alfalfa hay was superior to gamagrass hay for milk yield primarily due to greater intake.
Multicenter, Randomized, Double-Blind, Placebo-Controlled Study of Thalidomide Plus Dexamethasone Compared With Dexamethasone As Initial Therapy for Newly Diagnosed Multiple Myeloma (2008)

Thal/dex results in significantly higher response rates and significantly prolongs TTP compared with dexamethasone alone in patients with newly diagnosed MM.
Structural Basis by Which the N-Terminal Polypeptide Segment of Rhizopus chinensis Lipase Regulates Its Substrate Binding Affinity (2019)

Members of an important group of industrial enzymes, <i>Rhizopus</i> lipases, exhibit valuable hydrolytic features that underlie their biological functions. Particularly important is their N-terminal polypeptide segment (NTPS), which is required for secretion and proper folding but is removed in the process of enzyme maturation. A second common feature of this class of lipases is the α-helical "lid", which regulates the accessibility of the substrate to the enzyme active site. Some <i>Rhizopus</i> lipases also exhibit "interfacial activation" by micelle and/or aggregate surfaces. While it has long been recognized that the NTPS is critical for function, its dynamic features have frustrated efforts to characterize its structure by X-ray crystallography. Here, we combine nuclear magnetic resonance spectroscopy and X-ray crystallography to determine the structure and dynamics of <i>Rhizopus chinensis</i> lipase (RCL) with its 27-residue NTPS prosequence (r27RCL). Both r27RCL and the truncated mature form of RCL (mRCL) exhibit biphasic interfacial activation kinetics with <i>p</i>-nitrophenyl butyrate (<i>p</i>NPB). r27RCL exhibits a substrate binding affinity significantly lower than that of mRCL due to stabilization of the closed lid conformation by the NTPS. In contrast to previous predictions, the NTPS does not enhance lipase activity by increasing surface hydrophobicity but rather inhibits activity by forming conserved interactions with both the closed lid and the core protein structure. Single-site mutations and kinetic studies were used to confirm that the NTPS serves as internal competitive inhibitor and to develop a model of the associated process of interfacial activation. These structure-function studies provide the basis for engineering RCL lipases with enhanced catalytic activities.

A Comprehensive Multi-Nation Comparison of the Hunchback Heuristic and Mainstream Theories of Status-Based Judgements of Anger and Calm (2016)

The ANGCALM Consortium: Social psychology has faced considerable criticism in the last decade or so for the loose nature of its theories: for instance, the observation that it is often nearly impossible to disprove a psychological theory (Gelman and Loken, 2013), even as good theories allow for conditions that falsify them (Klein, 2014). With this in mind, our goal is to revisit and re-evaluate the fundamental elements of a number of mainstream theories that offer insights on status-based judgements of anger and calm. In particular, our investigation will compare explanations derived from the novel hunchback heuristic (Owuamalam, Weerabangsa, Karunagharan, and Rubin, 2016) with the more established cultural moderation hypothesis (Park et al., 2013). We will then test the performance of these newer theories against traditional theories of intergroup relations from which predictions can be generated about status-based anger and calm judgements. Three traditional theories are of interest here: the social identity theory’s reality caveat (Spears, Jetten, and Doosje, 2001); the stereotype content model (Fiske, Cuddy, Glick, and Xu, 2002) and the infra-humanization framework (Leyens et al., 2003). Ultimately, we want to see whether the newer theories add more to what we already could derive from traditional formulations.
