Articles problematics and specificity of creative style of Iraqi publicist Raphael Butti

The publicist and editor Raphael Butti was one of the pioneers of Iraqi social and political journalism. The study of his 400 articles between 1920 and 1956, have shown that the predominant direction of his work, the impulse for writing was the desire to promote and develop democratic institutions in Iraq. The subject matter of his publications was related to the need for freedom of choice, gender equality, freedom of speech and the press, and increasing the level of education of the individual. Applying the methods of problem-thematic, lexical-stylistic and comparative analysis of Rafael Butti's articles, the authors have revealed that almost all his articles are permeated by the theme of patriotism and reflect his broad outlook. At the same time, the relative paucity of the language and creative style of the Iraqi publicist was found, which is expressed, in particular, in the limited use of artistic expression. Rafael Butti focuses primarily on intellectual enlightenment, compensating for the lack of emotional messages with long analytical phrases, lengthy paragraphs, and lengthy headings

BLUES from Music: BLind Underdetermined Extraction of Sources from Music

In this paper we propose to use an instantaneous ICA method (BLUES) to separate the instruments in a real music stereo recording. We combine two strong separation techniques to segregate instruments from a mixture: ICA and binary time-frequency masking. By combining the methods, we are able to make use of the fact that the sources are differently distributed in both space, time and frequency. Our method is able to segregate an arbitrary number of instruments and the segregated sources are maintained as stereo signals. We have evaluated our method on real stereo recordings, and we can segregate instruments which are spatially different from other instruments

Environmental modification via a quorum sensing molecule influences the social landscape of siderophore production

Bacteria produce a wide variety of exoproducts that favourably modify their environment and increase their fitness. These are often termed ‘public goods’ because they are costly for individuals to produce and can be exploited by non-producers (‘cheats’). The outcome of conflict over public goods is dependent upon the prevailing environment and the phenotype of the individuals in competition. Many bacterial species use quorum sensing (QS) signalling molecules to regulate the production of public goods. QS therefore determines the cooperative phenotype of individuals, and influences conflict over public goods. In addition to their regulatory functions, many QS molecules have additional properties that directly modify the prevailing environment. This leads to the possibility that QS molecules could influence conflict over public goods indirectly through non-signalling effects, and the impact of this on social competition has not previously been explored. The Pseudomonas aeruginosa QS signal molecule PQS is a powerful chelator of iron which can cause an iron starvation response. Here we show that PQS stimulates a concentration-dependent increase in the cooperative production of iron scavenging siderophores, resulting in an increase in the relative fitness of non-producing siderophore cheats. This is likely due to an increased cost of siderophore output by producing cells and a concurrent increase in the shared benefits, which accrue to both producers and cheats. Although PQS can be a beneficial signalling molecule for P. aeruginosa, our data suggests that it can also render a siderophore-producing population vulnerable to competition from cheating strains. More generally our results indicate that the production of one social trait can indirectly affect the costs and benefits of another social trait

A novel method to quantify fibrin-fibrin and fibrin-α2AP cross-links in thrombi formed from human trauma patient plasma.

The widespread use of the anti-fibrinolytic agent, tranexamic acid (TXA), interferes with the quantification of fibrinolysis by dynamic laboratory assays such as clot lysis, making it difficult to measure fibrinolysis in many trauma patients. At the final stage of coagulation, Factor XIIIa (FXIIIa) catalyses the formation of fibrin-fibrin and fibrin-α2-antiplasmin (α2AP) cross-links which increases clot mechanical strength and resistance to fibrinolysis. Here, we develop a method to quantify fibrin-fibrin and fibrin-α2AP cross-links that avoids the challenges posed by TXA in determining fibrinolytic resistance in conventional assays. Fibrinogen alpha chain (FGA-FGA), fibrinogen gamma chain (FGG-FGG) and FGA-α2AP cross-links were quantified using liquid-chromatography-mass spectrometry (LC-MS) and parallel reaction monitoring (PRM) in paired plasma samples from trauma patients pre- and post-fibrinogen replacement. Differences in the abundance of cross-links in trauma patients receiving cryoprecipitate (cryo) or fibrinogen concentrate (Fg-C) were analysed. The study found that the abundance of cross-links was significantly increased in trauma patients post-cryo, but not Fg-C, transfusion (p < 0.0001). The abundance of cross-links was positively correlated with the toughness of individual fibrin fibres, the peak thrombin concentration and FXIII antigen (p < 0.05). We have developed a novel method that allows us to quantify fibrin cross-links in trauma patients who have received TXA, providing an indirect measure of fibrinolytic resistance. Using this novel approach we have avoided the effect of TXA and shown that cryo increases fibrin-fibrin and fibrin-α2AP cross-linking when compared to Fg-C, highlighting the importance of FXIII in clot formation and stability in trauma patients

Renormalized Path Integral for the Two-Dimensional Delta-Function Interaction

A path-integral approach for delta-function potentials is presented. Particular attention is paid to the two-dimensional case, which illustrates the realization of a quantum anomaly for a scale invariant problem in quantum mechanics. Our treatment is based on an infinite summation of perturbation theory that captures the nonperturbative nature of the delta-function bound state. The well-known singular character of the two-dimensional delta-function potential is dealt with by considering the renormalized path integral resulting from a variety of schemes: dimensional, momentum-cutoff, and real-space regularization. Moreover, compatibility of the bound-state and scattering sectors is shown.Comment: 26 pages. The paper was significantly expanded and numerous equations were added for the sake of clarity; the main results and conclusions are unchange

Stokes-operator-squeezed continuous-variable polarization states

We investigate nonclassical Stokes-operator variances in continuous-wave polarization-squeezed laser light generated from one and two optical parametric amplifiers. A general expression of how Stokes-operator variances decompose into two-mode quadrature operator variances is given. Stokes parameter variance spectra for four different polarization-squeezed states have been measured and compared with a coherent state. Our measurement results are visualized by three-dimensional Stokes-operator noise volumes mapped on the quantum Poincare sphere. We quantitatively compare the channel capacity of the different continuous-variable polarization states for communication protocols. It is shown that squeezed polarization states provide 33% higher channel capacities than the optimum coherent beam protocol

Genetic analysis of the flowering date and number of petals in rose

Rose is the ornamental species with the highest financial impact. Floral traits such as the number of petals and the date of flowering are major characteristics of ornamental plants. Our objective is to study the genetic determinism of floral traits: date of flowering and number of petals, which are a major issue for rose breeders. The study was conducted on two interspecific populations interconnected by the male parent: H190 x hybrid of Rosa wichurana (referred to as HW) and “The Fairy” x hybrid of Rosa wichurana (referred to as FW). The number of petals and the date of flowering were scored over 2 and 8 years, respectively. A new HW genetic map covering 468 cM and the already available genetic map of the FW population (Kawamura et al. TAG Theor Appl Genet 122:661–675, 2011) were used for the genetic determinism studies. In each population, half of the hybrids exhibited single flowers (less than 10 petals), whereas the other half revealed double flowers. The number of petals is controlled by the NP gene located on LG3. Additionally, we detected two new major quantitative trait loci (QTLs) on LG2 and LG5, close to RoAP1b and RoRAG, respectively, two genes involved in the control of floral identity. For the date of flowering, three QTLs with a major effect and high stability between years were found on linkage groups 3, 4, and 6, indicating a high stability of QTLs to the changing environment. Candidate genes underlying these QTLs were investigated and key genes were identified. These major QTLs were linked to candidate genes, i.e., the identified QTL on LG4 was linked to RoFT, the one on LG3 to genes involved in gibberellin pathways, and the one on LG6 to RoFD. These QTLs, which are very stable over time, are good candidates to develop markers applicable in marker-assisted selection (MAS)

E-retailing ethics in Egypt and its effect on customer repurchase intention

The theoretical understanding of online shopping behaviour has received much attention. Less focus has been given to the formation of the ethical issues that result from online shopper interactions with e-retailers. The vast majority of earlier research on this area is conceptual in nature and limited in scope by focusing on consumers’ privacy issues. Therefore, the purpose of this paper is to propose a theoretical model explaining what factors contribute to online retailing ethics and its effect on customer repurchase intention. The data were analysed using variance-based structural equation modelling, employing partial least squares regression. Findings indicate that the five factors of the online retailing ethics (security, privacy, non- deception, fulfilment/reliability, and corporate social responsibility) are strongly predictive of online consumers’ repurchase intention. The results offer important implications for e-retailers and are likely to stimulate further research in the area of e-ethics from the consumers’ perspective
