Hemisphere-Cylinder in Dynamic Pitch-Up Motions (1999)

Laser-Doppler velocimetry and seven-hole probes were employed to map out the velocity and vorticity field along a plane downstream of a hemisphere-cylinder. Steady flow data were obtained over a fixed model at a range of angles of attack, as well as over a model pitching through ramp motions to a final angle of attack. Attention was focused on the dynamic development of induced vortex asymmetry. It was found that the wake develops first in a symmetric fashion and asymmetry is generated with some time delay.
Applications of sonics and ultrasonics in geophysical prospecting (1999)

This paper describes some of the applications of acoustic techniques that are used in the exploration and production of hydrocarbons from underground reservoirs. Borehole sonic measurements (0.5 to 20 kHz) probe rock formations with depths of investigation extending up to a few meters, whereas ultrasonic measurements (80 kHz to 2.5 MHz) provide images of the borehole wall, casing corrosion monitoring, and evaluation of the annulus between casing and borehole. Newer applications of sonic measurements are in the estimation of formation anisotropy that may be caused by intrinsic microlayerings or thin beddings, aligned fractures, and tectonic stresses transverse to the borehole axis. The section on ultrasonic measurements covers open-hole imaging of breakouts and fractures intersecting the borehole, casing integrity inspection, and evaluation of cement sheath placed to support the casing and ensure isolation of hydrocarbon-bearing from water-bearing zones. These measurements are today carried out with pulse-echo techniques using travel time and amplitude processing for the first two applications and amplitude decay estimation of a casing resonance for the latter. Recent research topics include improvements in interpretation methodologies to extract more value from existing measurements as well as use of new transducer designs to remedy to the limitations of current cement evaluation techniques.
Ambient Measurements of Highly Oxidized Gas-Phase Molecules during the Southern Oxidant and Aerosol Study (SOAS) 2013 (2018)

We present measurements of highly oxidized multifunctional molecules (HOMs) detected in the gas phase using a high-resolution time-of-flight chemical ionization mass spectrometer with nitrate reagent ion (NO3– CIMS). The measurements took place during the 2013 Southern Oxidant and Aerosol Study (SOAS 2013) at a forest site in Alabama, where emissions were dominated by biogenic volatile organic compounds (BVOCs). Primary BVOC emissions were represented by isoprene mixed with various terpenes, making it a unique sampling location compared to previous NO3– CIMS deployments in monoterpene-dominated environments. During SOAS 2013, the NO3– CIMS detected HOMs with oxygen-to-carbon (O:C) ratios between 0.5 and 1.4 originating from both isoprene (C5) and monoterpenes (C10) as well as hundreds of additional HOMs with carbon numbers between C3 and C20. We used positive matrix factorization (PMF) to deconvolve the complex data set and extract information about classes of HOMs with similar temporal trends. This analysis revealed three isoprene-dominated and three monoterpene-dominated PMF factors. We observed significant amounts of isoprene- and monoterpene-derived organic nitrates (ONs) in most factors. The abundant presence of ONs was consistent with previous studies that have highlighted the importance of NOx-driven chemistry at the site. One of the isoprene-dominated factors had a strong correlation with SO2 plumes likely advected from nearby coal-fired power plants and was dominated by an isoprene-derived ON (C5H10N2O8). These results indicate that anthropogenic emissions played a significant role in the formation of low-volatility compounds from BVOC emissions in the region.
Certification of DOT 7A Type A Packaging in Type AF Configurations (2007)

Based on the U.S. Department of Transportation (DOT) regulations in 49 CFR 173.7(d), the U.S. Department of Energy (DOE) Order 460.1B (DOE 2003) codifies the authority of certification of Type-B and fissile material transportation packaging to the Office of Environmental Management (EM), except for materials of interest to national security, naval propulsion systems, and civilian radioactive waste management. DOE Order 460.1B also stipulates that the EM certification of Type B and fissile materials transportation packaging shall be in accordance with the U.S. Nuclear Regulatory Commission (NRC) safety standards in 10 CFR Part 71. The Packaging Certification Program (PCP) of the Office of Safety Management and Operations (EM-60) is supported by technical review teams at Argonne National Laboratory and Lawrence Livermore National Laboratory. In recent years EM-60 has received requests for certification of fissile material packages for the shipment of low-enrichment uranium oxides in DOT 7A Type A drums in Type AF configurations. One request originally sought for DOT exemption (i.e., special permit) per 49 CFR 107, Subpart B that underwent reviews by DOE, NRC, and DOT. DOT eventually advised DOE that the packaging should be certified as a DOT 7A Type A drums in a Type AF configuration. Historically EM-60 has also issued Certificate of Compliances (CoC) for low-enrichment fissile uranium metals in wooden boxes as Type B packages for shipment, even though the wooden boxes do not meet the structural and thermal requirements in 10 CFR 71 under hypothetical accident conditions. There are also provisions in 10 CFR 71.15 for exemption from classification as fissile material, and in 10 CFR 71.22 General license: Fissile material that specifically references the DOT requirements in 49 CFR 173.417(a) for Type A package. The myriad of NRC and DOT regulations applicable to fissile materials and Type A packages availed alternative approaches in the requests for packaging certification; however, in all cases the primary concern for fissile material packages is the assurance of criticality safety in the shipment under both normal conditions of transport and hypothetical accidents. This paper will present a case in the certification of DOT 7A Type A packaging in Type AF configurations, drawing highlights from a recent certification review of packagings for shipment of low-enrichment uranium oxides in Type A drums. Various regulatory requirements are also discussed.
Improving Both Quantity and Quality: Incentive Mechanism for Social Mobile Crowdsensing Architecture (2018)

Mobile crowdsensing has emerged as an efficient paradigm for performing large-scale sensing tasks. Improving both the quantity and quality of users is still the pivotal problem for mobile crowdsensing system. This paper gives a comprehensive solution to improve the quantity and quality of users simultaneously through the social mobile crowdsensing architecture. To incentive the users based on the novel architecture, we first propose a universal initial diffuser selection algorithm to accommodate two widely studied diffusion models and, then a lightweight, multi-metric comprehensive, and parameter-free user quality evaluation method is presented. Finally, we propose a reverse auction to optimize the new criterion, which takes both social cost and user quality into consideration. Through both rigorous theoretical analysis and extensive simulations, we demonstrate that the proposed incentive mechanisms achieve computational efficiency, individual rationality, truthfulness, and guaranteed approximation. Meanwhile, the proposed incentive mechanisms show prominent advantage in total unit quality cost and running time.

CRLM patients concomitant with hepatitis have adequate liver reserve function for major hepatic resection and have similar prognosis of patients without hepatitis.
A Cellular Mechanism of Learning-Induced Enhancement of Synaptic Inhibition: PKC-Dependent Upregulation of KCC2 Activation (2020)

Long-term memory of complex olfactory learning is expressed by wide spread enhancement in excitatory and inhibitory synaptic transmission onto piriform cortex pyramidal neurons. A particularly interesting modification in synaptic inhibition is the hyperpolarization of the reversal potential of the fast post synaptic inhibitory potential (fIPSP). Here we study the mechanism underlying the maintenance of such a shift in the fIPSP. Blocking of the neuronal specific K<sup>+</sup>-Cl<sup>-</sup> co-transporter (KCC2) in neurons of trained rats significantly depolarized the averaged fIPSP reversal potential of the spontaneous miniature inhibitory post synaptic currents (mIPSCs), to the averaged pre-training level. A similar effect was obtained by blocking PKC, which was previously shown to upregulate KCC2. Accordingly, the level of PKC-dependent phosphorylation of KCC2, at the serine 940 site, was significantly increased after learning. In contrast, blocking two other key second messenger systems CaMKII and PKA, which have no phosphorylation sites on KCC2, had no effect on the fIPSP reversal potential. Importantly, the PKC inhibitor also reduced the averaged amplitude of the spontaneous miniature excitatory synaptic currents (mEPSCs) in neurons of trained rats only, to the pre-training level. We conclude that learning-induced hyper-polarization of the fIPSP reversal potential is mediated by PKC-dependent increase of KCC2 phosphorylation.
Localized guided propagation modes in photonic crystals with shear discontinuities (2005)

Shear discontinuities in photonic crystals are a new type of defect which can support guided modes. We analyze the guided mode properties, including dispersion diagrams and group velocity dispersion, dependence of the confinement on the shear shift and shear position and the coupling between two shear discontinuity wave guides.
Control Location Selection Strategy for Power System Emergency Control (2006)

This paper analyzes the difficulties of emergency control and points out comparability of stability margin and transition of instability mode are the keys of emergency control. Then a revised normalized stability margin and a hidden mode identification method are proposed to solve these problems. Based on these work, an algorithm for control location selection is given. The cases of New-England system verified that the proposed algorithm can find the appropriate location for emergency control. It can work not only in same instability mode situation, but also in transferred instability mode situation.
Improving prediction accuracy using class-specific ensemble feature selection (2010)

As data accumulates at a speed significantly faster than can be processed, data preprocessing techniques such as feature selection become increasingly important and beneficial. Moreover, given the well-known gains of feature selection, any further improvements can positively affect a wide array of fields and applications. So, this research explores a novel feature selection architecture, Class-specific Ensemble Feature Selection (CEFS), which finds class-specific subsets of features optimal to each available classification in the dataset. Each subset is then combined with a classifier to create an ensemble feature selection model which is further used to predict unseen instances. CEFS attempts to provide the diversity and base classifier disagreement sought after in effective ensemble models by providing highly useful, yet highly exclusive feature subsets. CEFS is not a feature selection algorithm, but rather, a unique way of performing feature selection. Hence, it is also algorithm independent, suggesting that various machine learners and feature selection algorithms can benefit from the use of this architecture. To test this architecture, a comprehensive experiment is conducted, implementing the architecture under two different classifiers, three different feature selection algorithms, and under ten different datasets. The results of this experiment shows that the CEFS architecture outperforms the traditional feature selection architecture in every algorithmic combination and for every dataset. Moreover, the presence of high-dimensional datasets suggests that CEFS will scale up. Finally, the feature results obtained from the experiment suggest that vital class-specific information can be lost if feature selection is performed on the entire dataset as a whole, as opposed to a class-specific manner.
Off-line optimized pulse patterns for minimum distortion using the method of simulated annealing with the downhill simplex (2002)

In high power drives the switching frequency is limited by switching losses. In order to obtain minimum distortion at low switching frequency off-line optimized pulse patterns are used. The method of steepest gradient, used in the past, does not necessarily provide the best method. It has a tendency to be locked in the local minima. The method of simulated annealing applied along with the downhill simplex has the ability to modify the structure of the problem. In so doing it is able to avoid the local minima and reach a global minimum. This provides a simple effective means of pulse pattern optimization. Optimized pulse patterns are generated and the performance of this method is discussed.
Quantum Genetic Algorithm for the Design of Miniaturized and Reconfigurable IoT Antennas (2023)

This article leverages an automated quantum genetic algorithm (QGA) to design miniaturized antennas for Internet of Things (IoT) devices. The QGA implemented in this work automates the design process and enables the antenna designer to generate static or reconfigurable miniaturized microstrip folded antenna topologies. The QGA is also implemented to generate a pixelation pattern within the antenna radiating surface to optimally tune the antenna operation for IoT communication needs as well as for Wi-Fi operation. In this article, we also present a QGA-optimized folded miniaturized antenna in both static and reconfigurable topologies. The reconfiguration is achieved through a single radio frequency (RF) micro-electro-mechanical switch (RF MEMS) whose location is optimized through the automated process. The automated design process achieves 87% antenna size reduction at 868 MHz compared to a typical patch antenna operating at the same frequency. As a result, the static and reconfigurable antenna prototypes achieve good radiation efficiencies in comparison to their miniature size with acceptable gains thus satisfying the IoT physical and operational constraints. Both antennas are fabricated and tested, where excellent agreement is noticed between simulated and measured results.
Relationship between physical capacity and quality of life in workers university (2010)

Aim: Examine the relationship between the functional capacity and the quality of life related to health in university workers. Methodology: Cross-sectional study in 146 subjects, divided in two groups: Low functional Capacity ( 9.1 METs). We evaluated quality of life related to health (HRQOL-Health Questionnaire SF-12) and functional capacity (Questionnaire PAR/PAF) as indicators of health status. Results: 47.3% (69 men) and 52.7% (78 women). The average age of the groups was 35.0 ± 9.7 years (range 19,0-60,0 years). For HRQOL, the average found in the population assessed was 45.2 ± 4.42 (range 33,0-58,1) and 43.8 ± 6.87 (range 19,8-43,8) in components Physical Component Summary (PCS-12) and Mental Component Summary (MCS-12), respectively p = NS. Significant differences were found when comparing functional ability and sex, p<0,001 in both groups. Similarly, sex and mental component MCS-12 (group of Lower Functional) p = 0,049 as well as women and the physical component PCS-12, p = 0,05 between groups. Finally, a better score in HRQL observed in the group of High Capacity and functional components in both sex OR 0.59 (0.25-1.38). Conclusions: The results of this study demonstrate the relationship between High functional Capacity and a better HRQOL in this population.
Role of B-type natriuretic peptide (BNP) and NT-proBNP in clinical routine (2005)

In recent years biomarkers have emerged as important tools for diagnosis, risk stratification and therapeutic decision making in cardiovascular diseases. Cardiac troponins in particular have become the cornerstone for diagnostic work up of patients with acute coronary syndromes. Currently, several promising new biomarkers are under scientific investigation. Most of these new biomarkers, however, are not yet suitable for clinical application, with the exception of B-type natriuretic peptide (BNP) and its N-terminal fragment (NT-proBNP). Both markers have proven their diagnostic usefulness in a great number of studies and thus have progressed from bench to clinical application. This article aims to summarise existing data concerning BNP and NT-proBNP measurement in cardiovascular disorders and to outline how these markers can be integrated into clinical routine. Furthermore, future perspectives of these markers will be discussed.

B-type natriuretic peptide, which is also called brain-type natriuretic peptide (BNP), was first described in 1988 after isolation from porcine brain. However, it was soon found to originate mainly from the heart, representing a cardiac hormone.

BNP belongs to the natriuretic peptide family together with other structurally similar peptides, namely atrial natriuretic peptide (ANP), C-type natriuretic peptide (CNP), and urodilatin. The natriuretic peptides have in common a characteristic biochemical structure which consists of a 17 amino-acid ring and a disulfide bridge between two cysteine molecules. The major source of BNP synthesis and secretion is the ventricular myocardium. Whereas ANP is stored in granules and can be released immediately after stimulation, only small amounts of BNP are stored in granules and rapid gene expression with de novo synthesis of the peptide is the underlying mechanism for the regulation of BNP secretion. BNP is synthesised as a prehormone (proBNP) comprising 108 amino acids. Upon release into the circulation it is cleaved in equal proportions into the biologically active 32 amino acid …
Plenary lecture 2: convergence speed and population dynamics in the AK model with habit formation (2012)

AK-type models with habit formation have been used in the literature to address a wide variety of issues. For example, through numerical simulations, Carroll et al have shown that the introduction of habit formation in the standard AK endogenous growth model may cause this model to exhibit transitional dynamics, while Gomez has proved that the convergence speed of the AK model with external habits is higher than that in the AK model with internal habits. It is known that usually standard economic growth theory assumes that labor (population) force grows at a positive constant rate (Malthusian model). However, this assumption is not a good approximation to reality as population exponentially grows without limits, which is clearly unrealistic. To remove the prediction of unbounded population size in the very long-run, Verhulst wrote an alternative model, known as the logistic growth model, where the population stock evolves according to an elongated S-curve. Recent forecasts (e.g., United Nations) confirm that the annual growth rate of population is expected to fall gradually until 2100, and that world population will stabilize at a level of about eleven billion people by 2200. Thus, not only theoretically but also empirically, it seems reasonable to model population size as following a logistic process. Bucci and Guerrini, Ferrara and Guerrini, Germana' and Guerrini, and Guerrini, have recently explored the implications of studying some economic growth models within a framework where the change over time of the labor force is non constant but governed by the logistic law or by a bounded population growth rate. In this paper, we wish to investigate the dynamic effects of assuming a logistic population growth hypothesis in Gomez's model. This set-up leads the economy to be described by a four dimensional dynamical system, whose unique non-trivial steady state equilibrium is a saddle point with a two dimensional stable manifold. Two stable roots, rather than only one as in Gomez, determine the speed of convergence. Now, the crucial determinant of the asymptotic speed of convergence is the larger of the two negative eigenvalues. As a result, contrary to Gomez, the asymptotic speed of convergence may be not necessarily decreasing as the value of some parameter increases.
