A Generic Approach to QoS-Based Transceiver Optimization

We propose a generic framework for jointly optimizing the transmit power allocation and the adaptive receive strategies in a multiuser network with individual quality-of-service (QoS) requirements. The QoS is assumed to be a one-to-one mapping of the signal-to-interference-plus-noise ratio (SINR). The feasibility of certain target QoS depends on the mutual interference and on a given sum-power constraint. This coupling can be modeled by interference functions, which determine how the transmit powers cause interference to the individual users. We show fundamental properties, like continuity and feasibility for the most general case when the functions are defined by axioms. Additional properties are shown for the case when the interference functions are based on a parameter-dependent coupling matrix, which allows to apply techniques from the theory of nonnegative matrices. We derive a class of iterative algorithms, which exploit the matrix structure. The proposed iteration converges monotonically to the global optimum. Starting from the same initialization, it is better than the known fixed-point iteration. It achieves arbitrary QoS values within the QoS-feasible region.
Dichloromethane Detection Based on Near-Infrared Absorptive Sensing

Dichloromethane (DCM), a clear and lipophilic liquid that has been primarily used in industrial applications, has caused organic poisoning upon inhalation during its wide use as a chlorinated organic solvent and in other industrial processes. In this paper, a biophotonic near-infrared sensor using a tunable fiber ring laser based on an absorption spectroscopic method has been demonstrated in order to perform DCM detection. A continuous wave near-infrared source operating in the C-band wavelength range has been developed and optically characterized. The principle of the Sagnac loop mirror, which operates as a saturable absorber to effectively narrow down the laser linewidth, has been reviewed. By forming a fiber-based interferometer loop with an unpumped erbium-doped fiber inserted, we could reduce the external noise and stabilize the laser frequency to achieve a narrow linewidth. The result shows an accuracy of 16 pm or 0.06 cm -1, which is much more precise than the previous results of 1 nm or 4 cm -1 using a method based on a broadband infrared light source.
Mixed One-and Two-Sided Real Uncertainty: A Vertex Result

This note deals with the robustness margin of generalized stability for a parametrized family of real matrices in the case when some of the parameters are known to be no larger (or no smaller) than their nominal value ("one-sided uncertainty"). It is observed that this robustness margin can be computed in terms of a modified structured singular value, with or without frequency sweep. Whether or not one-sided uncertainty is present, if a certain multiaffineness condition is satisfied, a vertex result holds.
Finding external indicators of load on a web server via analysis of black-box performance measurements

Traditional methods for system performance analysis have long relied on a mix of queuing theory, detailed system knowledge, intuition, and trial-and-error. These approaches often require construction of incomplete gray-box models that can be costly to build and difficult to scale or generalize. In this thesis, we present a black-box analysis method to discover the amount of load on a web server with minimal knowledge of its internal mechanisms. In contrast to white-box analysis, where a system's internal mechanisms can help to explain its behavior, black-box analysis relies on external measurements of a system's reactions to well-understood inputs. The primary advantages of black-box analysis are its relative independence from specific architectures, its applicability to opaque environments (e.g., closed-source systems), and its scalability. In this thesis, we show that statistical analyses of web server response times can be used to discover which server resources are stressed by particular workloads. We also show that under certain conditions, the settling period of server response times after resource perturbation correlates positively with the degree of perturbation. Finally, we use the two-sample Kolmogorov-Smirnov (KS) test to measure statistical equality of multiple samples drawn from response times of a server under various steady-state load conditions. We show that in specific circumstances, the number of samples that test as statistically equal can serve as an imprecise indicator of the amount of load on a server. All of these contributions will aid performance analysis in new environments such as cloud computing, where internal server mechanisms and configurations change dynamically and structural information is hidden from users.
Quality of Life in Acromegaly

Available disease-specific questionnaires like the Acromegaly Quality of Life questionnaire have confirmed that quality of life (QoL) is impaired in acromegaly, especially in active disease. Successful therapy improves QoL, but it may not normalize completely even after endocrine cure; furthermore, there is not always a correlation between growth hormone (GH) and insulin-like growth factor 1 and subjective health perception of QoL. Appearance is the dimension most affected and has the highest impact on the patient's QoL. Worse QoL is associated with the presence of musculoskeletal pain, headache (if only medical therapy, not surgery, has been provided), having required treatment with radiotherapy, being older, of female gender, with a longer disease duration, coexisting diabetes mellitus, a higher BMI or becoming GH deficient after treatment for acromegaly.
Intranasal exposure to Stachybotrys chartarum enhances airway inflammation in allergic mice.

RATIONALE Exposure to building dampness, often associated with growth of microbes such as Stachybotrys chartarum, has been linked to respiratory symptoms. We have shown previously in a murine model that exposure to S. chartarum can induce lung inflammation characterized by infiltration of neutrophils and lymphocytes; this process is regulated by proinflammatory cytokines and leucocyte-attracting chemokines. OBJECTIVES Because an atopic predisposition may influence the response to microbes, we examined the effects of S. chartarum on allergic mice in an experimental model. BALB/c mice were sensitized to ovalbumin by intraperitoneal injections and exposed for 3 wk to spores of S. chartarum. MEASUREMENTS AND MAIN RESULTS Numbers of eosinophils and neutrophils were drastically increased in bronchoalveolar fluid from these mice as compared with the ovalbumin-sensitized/challenged mice or those exposed to S. chartarum without ovalbumin sensitization. Histologic sections showed severe granulomatous inflammatory cell infiltrates in all compartments of the lung, including peribronchial, perivascular, and alveolar spaces. The mRNA levels of proinflammatory cytokines interleukin-1beta and tumor necrosis factor alpha and the chemokine CCL3/MIP-1alpha were also markedly increased in the lungs. Despite the enhancement of the pulmonary inflammatory reaction, exposure to S. chartarum spores significantly down-regulated airway hyperresponsiveness and showed a tendency to decrease levels of Th2 cytokines in the lung. CONCLUSION Exposure to S. chartarum modulates the inflammatory reaction and airway hyperresponsiveness, depending on the allergic status of the exposed mice.
Preparation of Mg–Al layered double hydroxide intercalated with Coomassie Brilliant Blue R anion and its uptake of aromatic compounds from aqueous solutions

The objective of this study is to evaluate the capacity of Mg–Al layered double hydroxide (Mg–Al LDH) intercalated with organic dye to adsorb aromatic compounds in aqueous solutions. Mg–Al LDH intercalated with Coomassie Brilliant Blue R anion (BB−) was prepared by coprecipitation. The BB−-intercalated Mg–Al LDH was able to adsorb aromatic compounds from an aqueous solution, despite the electron density in the benzene ring of the aromatics. This uptake is caused by π–π stacking interactions, either between the electron-rich benzene rings of intercalated BB− and the benzene rings of aromatics with a low electron density or between the electron-poor benzene rings of intercalated BB− and the benzene rings of the aromatics with a high electron density.
The Use of an Enzyme-linked Immunosorbent Assay for Diagnosis of Actinobacillus pleuropneumoniae Infection in Pigs.

Introduction The disease porcine Haemophilus pleuropneumonia (PHP) is caused by a bacterium Actinobacillus pleuropneumoniae. This is a fastidious species whose growth must be supported by a rich medium containing nicotinamide-adenine dinucleotide, also known as "V Factor". Serum in the growth medium and incubation in an atmosphere of 5% carbon dioxide enhance growth of strains isolated from naturally occurring disease. Blood is often added to the medium so that hemolysis can be observed. Despite provision of these special growth conditions, one may have difficulty recovering the organism from specimens that have been improperly handled before arrival at the bacteriology laboratory. Consequently, there may be many cases of PHP disease that are not confirmed by isolation of the organism (1). The classical description of PHP is of an acute or peracute pleuropneumonia in which pigs that are apparently healthy the previous day are found dead. The careful observer may notice clinical signs of disease referable to gram-negative bacterial septicemia and pneumonia. These include increased body temperature, vomiting, lethargy, dyspnea, and cyanosis (2). The gross postmortem examination reveals massive fibrinous exudate in the pleural cavity, with hemorrhage and necrosis in the lung parenchyma. The lesions are diffuse in the peracute disease and are often more circumscribed in acute or subacute cases so that the lung may have a "checkerboard" appearance. Despite the rapid progress and severity of this disease, not every pig that is infected with A. pleuropneumoniae develops clinical disease. The infection has been confirmed in apparently healthy pigs by special bacteriological techniques (1,3). These "healthy" carriers are assumed to be the primary means by which PHP is spread to previously uninfected herds. When the disease is introduced into a herd, there is usually a brief epizootic with acute mortality followed by enzootic chronic disease. Acute mortality and chronic unthriftiness produce the substantial economic loss sustained by swine producers (4-6). However, the organism is not always isolated from infected pigs, and the economic consequences of spreading the disease can be substantial. If there was an accurate serological test to detect individual pigs or herds that have been exposed to A. pleuropneumoniae, then chronic carriers could be excluded from herds that were free from infection. Consequently, we sought to test the hypothesis that "It is possible to differentiate exposed from unexposed pigs (or herds) on the basis of ELISA results. "
The ParisNLP entry at the ConLL UD Shared Task 2017: A Tale of a #ParsingTragedy

We present the ParisNLP entry at the UD CoNLL 2017 parsing shared task. In addition to the UDpipe models provided, we built our own data-driven tokenization models, sentence segmenter and lexicon-based morphological analyzers. All of these were used with a range of different parsing models (neural or not, feature-rich or not, transition or graph-based, etc.) and the best combination for each language was selected. Unfortunately, a glitch in the shared task’s Matrix led our model selector to run generic, weakly lexicalized models, tailored for surprise languages, instead of our dataset-specific models. Because of this #ParsingTragedy, we officially ranked 27th, whereas our real models finally unofficially ranked 6th.
Security review of email summarization systems

There are hundreds of email summarization tools nowadays. One of the challenging issues of email summarization is to determine how to secure email summaries from spoofing and bombing and to provide preventive measures. Email is one of the most ubiquitous applications used on a daily basis by millions of people world-wide, traditionally accessed over a fixed terminal or laptop computer. In the past years, there has been an increasing demand for email access over mobile phones too. Our work focused on providing security review measures and preventing approaches that provide quality email summaries with secure transmissions over the network.
Nuclear GIT2 Is an ATM Substrate and Promotes DNA Repair

ABSTRACT Insults to nuclear DNA induce multiple response pathways to mitigate the deleterious effects of damage and mediate effective DNA repair. G-protein-coupled receptor kinase-interacting protein 2 (GIT2) regulates receptor internalization, focal adhesion dynamics, cell migration, and responses to oxidative stress. Here we demonstrate that GIT2 coordinates the levels of proteins in the DNA damage response (DDR). Cellular sensitivity to irradiation-induced DNA damage was highly associated with GIT2 expression levels. GIT2 is phosphorylated by ATM kinase and forms complexes with multiple DDR-associated factors in response to DNA damage. The targeting of GIT2 to DNA double-strand breaks was rapid and, in part, dependent upon the presence of H2AX, ATM, and MRE11 but was independent of MDC1 and RNF8. GIT2 likely promotes DNA repair through multiple mechanisms, including stabilization of BRCA1 in repair complexes; upregulation of repair proteins, including HMGN1 and RFC1; and regulation of poly(ADP-ribose) polymerase activity. Furthermore, GIT2-knockout mice demonstrated a greater susceptibility to DNA damage than their wild-type littermates. These results suggest that GIT2 plays an important role in MRE11/ATM/H2AX-mediated DNA damage responses.
A heuristic approach for local path planning in 3D environments

In this paper we describe a heuristic potential based technique for solving the problem of path planning based on local information for a free flying robot (FFR) in a 3D static environment. A path which maximizes the sum of three functions: (repulsion from obstacles, attraction towards the goal, and level attraction) is chosen. While the repulsive and goal-attraction potentials depend on how close is the FFR from obstacles and goal, respectively, the level-attraction potential maintains a certain altitude at which the FFR should navigate. Two additional heuristics are proposed to overcome the local minima problem and to improve the efficiency of the search process. Simulation results of the proposed technique are presented.
Investigating Some Technical Improvements to Glueball Calculations

We briefly discuss some issues concerning including the pseudoscalar glueball interpolating operators into the variational basis for computing the masses of the eta and etaprime mesons. As a start we present some preliminary results for the correlators from pseudoscalar glueball operators on nf = 2+1+1 twisted mass gauge configurations. Preliminary results for the effect of open boundary conditions on the masses of three glueballs computed in quenched QCD are presented. The statistics of glueball correlators are briefly discussed.
Perceptually accurate display of two greyscale images as a single colour image

Life scientists often desire to display the signal from two different molecular probes as a single colour image, so as to convey information about the probes’ relative concentrations as well as their spatial corelationship. Traditionally, such colour images are created through a merge display, where each greyscale signal is assigned to different channels of an RGB colour image. However, human perception of colour and greyscale intensity is not equivalent. Thus, a merged image display conveys to the typical viewer only a subset of the absolute and relative intensity information present in and between two greyscale images. The Commission Internationale de l'Eclairage L*a*b* colour space (CIELAB) has been designed to specify colours according to the perceptually defined quantities of hue (perceived colour) and luminosity (perceived brightness). Here, we use the CIELAB colour space to encode two dimensions of information about two greyscale images within these two perceptual dimensions of a single colour image. We term our method a Perceptually Uniform Projection display and show using biological image examples how these displays convey more information about two greyscale signals than comparable RGB colour space‐based techniques.
Regulation of cytokine gene expression by adjuvants in vivo

Antibody isotype affects biological activity of the antibodies and therefore should be considered in prevention of disease by vaccination. In previous reports, we demonstrated that adjuvants affect the antibody isotype switching process and favour the production of certain isotypes. The present study extends these findings and shows fundamental differences in the cytokine induction pattern according to the adjuvant used. Cytokine mRNA levels were determined by in situ RNA–RNA hybridization performed on splenocytes isolated from mice injected with different adjuvants. The results revealed that Freund's complete adjuvant (FCA), Freund's incomplete adjuvant (FIA), Al(OH)3 and QuilA administration results in a type‐2 (humoral) response, increasing IL‐4, IL‐5 and IL‐13 gene expression, while poly I:C exhibits a type‐1 (cell‐mediated) response, increasing the production of interferon‐gamma (IFN‐γ), IL‐2 and IL‐6 mRNA. Finally, BeSO4 and poly A:U augment IL‐5 and IL‐6 mRNA production, while lipopolysaccharide (LPS) and LiCl augment IL‐6 and tumour necrosis factor‐alpha (TNF‐α) mRNA production. Also, the adjuvants appear capable of overcoming the inherent IL‐2/IFN‐γ and IL‐4 dichotomy of C57Bl/6 and BALB/c mice, respectively, in response to cellular antigens such as Leishmania and herpessimplex virus (HSV). The overall data suggest that adjuvants direct the isotype switching process via induction of certain cytokines, a finding that can be useful in selection of the most efficient isotype of protective antibodies for disease prevention by vaccination.
Tetrabromido(di-2-pyridylamine-κ2 N 2,N 2′)platinum(IV)

The PtIV ion in the title complex, [PtBr4(C10H9N3)], is six-coordinated in a slightly distorted octahedral environment by two pyridine N atoms from a chelating di-2-pyridylamine (dpa) ligand and four Br− anions. The complex molecule has mirror symmetry, with the PtIV atom, two Br atoms and the central N atom of the dpa ligand lying on the mirror plane. The dpa ligand is not planar, showing a dihedral angle of 34.7 (2)° between the pyridine rings. The complex molecules are connected by intermolecular N—H⋯Br hydrogen bonds, forming chains along [001]. Intermolecular C—H⋯Br hydrogen bonds and π–π interactions between the pyridine rings [centroid–centroid distance = 3.667 (4) Å] are also observed.
Developing mathematical method for multi alignment of DNA sequences with weak similarity

A new mathematical method is proposed for constructing multiple alignment of weakly similar amino acid or nucleotide sequences. The method uses a multiple alignment representation in the form of position-weight matrices (PWM) and global dynamic programming. An optimization procedure for PWM is developed with the aim of finding a multiple alignment with maximum statistical significance. The method allows to find multiple alignment of sequences with the number of nucleotide or amino acid substitutions more than 2.5. The developed approach is applied to obtain multiple alignment of promoter sequences of 600 DNA bases length.
Open-Switch Fault Tolerance Control for a Three-Level NPC/T-Type Rectifier in Wind Turbine Systems

Three-level topologies are widely used in back-to-back converters of wind turbine generation (WTG) systems. In comparison with a conventional two-level topology, three-level topologies have more advantages, particularly for the high power. Neutral-point clamped (NPC) and T-type are typical three-level topologies. An open-switch fault of a three-level rectifier that is connected to a permanent-magnet synchronous generator (PMSG) leads to the current distortion and torque vibration in WTG systems. Furthermore, WTG systems can break down in the worst case. Therefore, a tolerance control for open-switch faults is required to improve the reliability of WTG systems. WTG systems by applying the tolerance control can be stopped safely and prevent additional problems. Depending on the situation, it can keep the operation of WTG systems under open-switch fault. The effects of outer open-switch faults of three-level rectifiers are analyzed by considering PMSG specifications in this paper. Moreover, a tolerance control for outer open-switch faults of the NPC and T-type three-level rectifiers are proposed with existing tolerance controls for inner open-switch faults. The proposed tolerance control is to inject the exact $d$-axis current value to eliminate current distortion. The simulation and experiment are conducted to prove the feasibility of the proposed tolerance control and to identify its performance.
Repeatability of Respiratory Impedance and Bronchodilatory Response in Asthmatic Children

We measured 53 school aged children using standard spirometry and oscillometry using the tremoFlo system, with 3 repeated measures both before and after an inhaled bronchodilator. We calculated the sensitivity to BD as the %change in FEV1, Rrs and Xrs, and we calculated the variability of these measures using their coefficient of variation. We developed the signal to noise ratio as the sensitivity normalized to the COV as the SNR_BD_FEV1, SNR_BD_Rrs and the SNR_BD_Xrs. We found that, in response to BD, FEV1 increased by 7.1(6.2)%, while Rrs decreased by 25.3(10.5)% and Xrs became less negative by 26.9 (20.5)%. However both Rrs and Xrs were more variable, with their COVs about 2.5-fold and 6-fold respectively greater than the COV of FEV1. Importantly when we compared the SNR_BD between impedance measurements (FOT) and FEV1, we found that while the SNR_BD for Xrs5 and FEV1 were not significantly different, the SNR_BD for Rrs5 was nearly 2 times greater than SNR_BD for FEV1 (p < 0.0005). This means Rrs at 5 Hz may be a more useful measure of the response to a bronchodilator in children with mild asthma. In conclusion, since oscillometry had better signal-to-noise, and is easier for patients to perform, and because it directly measures the difficulty of moving air in the respiratory system, we recommend oscillometry to assess reversibility in children with asthma.
The Time Change of the Consumer Price Index Response to the Supply Chain Management in the Supply of Money in the Iraqi Economy

The broadly acknowledged notion on inflation is that it is a money related event. Henceforth the decrease of expansion is to a great extent the domain of financial approach. This investigation is carried out with an objective to determine the direction and significance the relationship among money supply and inflation. Consumer price index is used as proxy of inflation while M2 is used to determine money supply in the country. We applied ARDL model to investigate long run relationship among the variables. The data used for this estimation is ranging from 1960 to 2017. Results of the study describe a unidirectional relationship from money supply to inflation. Therefore, a significant and positive long run relationship has established in Iraqi economy. Hence, monetarist point of view is prevailed in Iraqi economy. It is recommended that Iraqi government should tighten its monetary policy to control inflation within an acceptable range.
