Watchdogs in the Social Network: A Polarized Perception?

Created in the end of 2015 and currently approaching the mark of 200 thousand followers, the Facebook page “Os Truques da Imprensa Portuguesa” [The Tricks of the Portuguese Press] posts critical remarks on the news of national media and their supposed editorial criteria. The page has often generated heated debates on the platform, either being praised for its role as a watchdog, or discredited as allegedly serving as the spokesperson for a hidden political agenda. Until recently, the anonymity of their writers was one of the arguments for this accusation, but when the identity of one of the admins was disclosed, promptly followed by the self-disclosure of both, this premise was rebutted. This paper is focused on the reactions to the post on July 9th 2017 in which the admins revealed their names. Our goal is to evaluate the debate generated by this post, in particular concerning the polarization of positions and arguments among those that engaged with the post. To this end, we conduct a mostly exploratory research supported by visual network analysis and textual analysis. We first provide a global characterization of the page, and subsequently present some insights on the revealing post advanced by visual network analysis. Lastly, we look into textual content considering the “global mindset” of the discussion (topics, subtopics, and positionings for and against the page or the post), looking for eventual differences between the subsets of more active and less active commenters. We conclude that the engagement with the post (especially comments) was less polarized than expected, although with one notable exception, and that the relevance of the post rested more in its potential to fuel the debate around contemporary changes and practices in journalism and its multiple dimensions than in the positionings themselves.
Types and typechecking for Communicating Quantum Processes

We define a language CQP (Communicating Quantum Processes) for modelling systems that combine quantum and classical communication and computation. CQP combines the communication primitives of the pi-calculus with primitives for measurement and transformation of the quantum state; in particular, quantum bits (qubits) can be transmitted from process to process along communication channels. CQP has a static type system, which classifies channels, distinguishes between quantum and classical data, and controls the use of quantum states. We formally define the syntax, operational semantics and type system of CQP, prove that the semantics preserves typing, and prove that typing guarantees that each qubit is owned by a unique process within a system. We also define a typechecking algorithm and prove that it is sound and complete with respect to the type system. We illustrate CQP by defining models of several quantum communication systems, and outline our plans for using CQP as the foundation for formal analysis and verification of combined quantum and classical systems.
Complete W3C-Semantic’s Interpretations of AP-RDF

- An attributed predicate RDF (AP-RDF) has been proposed as a new alternative model to represent complex information. AP-RDF augments the function of predicate to hold attributes to present any additional triples of the main triple. AP-RDF has shown its usefulness in the beginning work by showing much better performance in terms of query time. In this work, we focus on studying whether AP-RDF fulﬁls the default semantic interpretation of the W3C Recommendation. In the end, we can show that AP-RDF fulﬁls the default semantic interpretation by extending the interpretation of property with the interpretation of predicate type. The impact of semantic interpretation shows on the retrieval process, especially on complex queries. It returns better performance compared to default RDF.
On the electrostatic control achieved in transistors based on multilayered MoS2: A first-principles study

In this work, the electrostatic control in metal-oxide-semiconductor field-effect transistors based on MoS2 is studied, with respect to the number of MoS2 layers in the channel and to the equivalent oxide thickness of the gate dielectric, using first-principles calculations combined with a quantum transport formalism. Our simulations show that a compromise exists between the drive current and the electrostatic control on the channel. When increasing the number of MoS2 layers, a degradation of the device performances in terms of subthreshold swing and OFF currents arises due to the screening of the MoS2 layers constituting the transistor channel.
Stakeholder engagement: the case of the Russian largest oil and gas companies

The study aims to analyse the practice of stakeholder management in seven largest Russian oil and gas companies. The methodological basis includes the stakeholder concept, the concept of corporate social responsibility and the concept of corporate sustainability. The author verifies a number of hypothesis, such as active engagement with the first level stakeholders, especially the state; stakeholder engagement is implemented by a Department for Corporate Social Responsibility and(or) a Department for Sustainable Development; the higher the degree of a company’s transparency, the more the issues of stakeholder engagement are revealed. The research method is a case study of seven Russian oil and gas companies, which allows not only identifying internal processes of stakeholder engagement within these companies, but also conducting a comparative analysis of stakeholder management. The information base includes the companies’ official websites, annual and non-financial reports, as well as АА1000SES, GRI G4, GRI Standards. The author provides a definition of stakeholder management and discusses the companies’ key stakeholders and divisions engaging with stakeholders, engagement instruments, etc. The research results disprove the first and second hypotheses and confirm the third hypothesis. The paper proposes measures to enhance interaction with stakeholders of the companies examined.
Birth outcome in women with breast cancer, cutaneous malignant melanoma, or Hodgkin’s disease: a review

Background: Data on birth outcome in women diagnosed with cancer before, during, or shortly after pregnancy are very sparse. The purpose of this review was to summarize the existing epidemiologic evidence of the adverse effect of breast cancer, cutaneous malignant melanoma, and Hodgkin’s disease on birth outcome. Methods: The MEDLINE database was used to review the literature systematically. Studies that examined the following outcomes were included: preterm birth, low birth weight, low birth weight at term, stillbirths, congenital abnormalities, male proportion of newborns, and mean birth weight. Studies were grouped according to whether the woman had been diagnosed with the specific cancer before, during, or shortly after pregnancy. Results: Few data exist on birth outcome in women with breast cancer, melanoma, or Hodgkin’s disease. The overall results from the limited number of studies, which included a comparison group for birth outcome, were reassuring. However, for women diagnosed with breast cancer before pregnancy, the only 2 studies that included comparison groups for birth outcome had conflicting results regarding the risk of preterm birth and congenital abnormalities. Furthermore, a recent cohort study of birth outcome in women who were diagnosed with Hodgkin’s disease before pregnancy indicated a slightly increased risk of congenital abnormalities among the newborns. Conclusion: Overall, the existing studies offer reassuring results concerning the risks of adverse birth outcome for women diagnosed with breast cancer, melanoma, or Hodgkin’s disease before, during or shortly after pregnancy. A limitation of most studies was the imprecise risk estimates caused by the small number of adverse birth outcomes and the lack of results stratified by treatment. Therefore, international collaboration is necessary in the future, to obtain more precise risk estimates for adverse birth outcomes, and to allow stratified analyses according to, for example, treatment.

Effective Face Recognition using Adaptive Multi-scale Transformer-based Resnet with Optimal Pattern Extraction

—Human face is the major characteristic for identifying a person and it helps to differentiate each person. Face recognition methods are mainly useful for determining a person’s identity with the help of biometric techniques. Face recognition methods are used in many practical applications like criminal identification, the phone unlocks systems and home security systems. It does not need any key and card, and it only requires facial images to provide high security over several applications. The interdependencies of the encryption methods are highly reduced in the deep learning-enabled face recognition models. Conventional methods did not satisfy the present demand due to poor recognition accuracy. Therefore, an advanced deep learning-based face recognition framework is implemented to authenticate the identity of individuals with high accuracy by using facial images. The required facial images are taken from the standard databases. The collected images are preprocessed using median filtering. The preprocessed facial images are subjected to spatial feature extraction, where the Local Binary patterns (LBP) and Local Vector Patterns (LVP) are utilized to extract the relevant optimal patterns from the facial images. Here, optimal pattern extraction is done with the Improved Rat Swarm Optimization Algorithm (IRSO). Then, the facial recognition is done over the extracted optimal features with the usage of the implemented Adaptive Multi-scale transformer-based Resnet (AMT-ResNet), where the parameters in the recognition network are optimized by using the IRSO. The efficiency of the developed deep learning adopted face recognition model is validated through different heuristics algorithms, and baseline face recognition approaches.
2. Introduction

regulates the localization and activity of the chromosomal passenger complex in meiosis and mitosis in Drosophila melanogaster. Open Biol. 4: 140162. Subject Area: cellular biology/genetics/molecular biology/ structural biology Polo kinase regulates the localization and activity of the chromosomal passenger complex in meiosis and mitosis in Drosophila melanogaster 1. Summary Cell cycle progression is regulated by members of the cyclin-dependent kinase (CDK), Polo and Aurora families of protein kinases. The levels of expression and localization of the key regulatory kinases are themselves subject to very tight control. There is increasing evidence that crosstalk between the mitotic kinases provides for an additional level of regulation. We have previously shown that Aurora B activates Polo kinase at the centromere in mitosis, and that the interaction between Polo and the chromosomal passenger complex (CPC) component INCENP is essential in this activation. In this report, we show that Polo kinase is required for the correct localization and activity of the CPC in meiosis and mito-sis. Study of the phenotype of different polo allele combinations compared to the effect of chemical inhibition revealed significant differences in the localization and activity of the CPC in diploid tissues. Our results shed new light on the mechanisms that control the activity of Aurora B in meiosis and mitosis. Cell cycle progression is regulated by reversible phosphorylation [1]. Protein kinases and phosphatases control the correct levels of phosphorylation of key sub-strates to ensure smooth progression of the cell cycle [1,2]. Frequently, these substrates are themselves kinases or phosphatases that form part of complex regulatory networks involving multiple feedback loops [1]. A group of highly conserved protein kinases is responsible for the overall control of these regulatory networks. This group includes the families of cyclin-dependent kinases (CDKs) [3], Aurora kinases [4,5] and Polo-like kinases (Plks) [6]. Misexpression of these protein kinases is linked to aneuploidy and carcinogenesis, making them very attractive targets for the development of new anti-cancer therapies [7–10]. The levels and activity of the master regulatory kinases must therefore be very tightly regulated. Regulation of the mitotic kinases occurs at multiple levels including modulation of their expression, proteolysis and targeting to different subcellular locations. Additionally, their enzymatic activity is regulated by specific cofactors and by the level of phosphorylation of activation segments—either by autophos-phorylation or by the action of other kinases and phosphatases (for reviews, see [5,6,11]). There is increasing evidence of crossregulation among CDKs, Polo-like and Aurora kinases. …

Review of road traffic control strategies

Traffic congestion in urban road and freeway networks leads to a strong degradation of the network infrastructure and accordingly reduced throughput, which can be countered via suitable control measures and strategies. After illustrating the main reasons for infrastructure deterioration due to traffic congestion, a comprehensive overview of proposed and implemented control strategies is provided for three areas: urban road networks, freeway networks, and route guidance. Selected application results, obtained from either simulation studies or field implementations, are briefly outlined to illustrate the impact of various control actions and strategies. The paper concludes with a brief discussion of future needs in this important technical area.
Human immunodeficiency virus type 1 reverse transcriptase genotype and drug susceptibility changes in infected individuals receiving dideoxyinosine monotherapy for 1 to 2 years

The genetic mechanisms of human immunodeficiency virus type 1 (HIV-1) resistance to dideoxyinosine (ddI) in vivo have been described based on data from primary HIV-1 isolates. To better define the spectrum of HIV-1 reverse transcriptase (RT) changes occurring during ddI therapy, we determined the genotype and ddI susceptibility of the RT gene of HIV RNA isolated from the plasma of 23 patients who had received 1 to 2 years (mean, 87 +/- 16 weeks) of ddI monotherapy. Population-based sequencing of plasma virus showed that 12 of 23 (52%) patients developed known ddI resistance mutations: L74V (7 patients), K65R (2 patients), L74V with M184V (3 patients), and L74V with K65R (1 patient). Five patients developed one or more known zidovudine resistance mutations (at codons 41, 67, 70, 215, and/or 219) during the study. Other amino acid substitutions were found, but only S68G and L210W occurred in more than one patient. Studies of sensitivity to ddI were performed on population-based recombinant-virus stocks generated by homologous recombination between a plasmid containing an HXB2 clone with the RT gene deleted and RT-PCR products of the RT genes from patients' plasma RNA. The sequences of the virus stocks produced by this procedure were typically identical to the sequence of the input PCR product from plasma RNA. Both an MT-2 cell-based culture assay and a cell-free virion-associated RT inhibition assay showed that viruses possessing an L74V and/or M184V mutation or a K65R mutation had reduced sensitivity to ddI. Viruses without these specific mutations had no change in sensitivity to ddI. The results presented here show that the spectrum of RT mutations in a population of patients on ddI monotherapy is more complex than previously described. The development of multiple mutational patterns, including those that confer resistance to other nucleoside analogs, highlights the complexity of using the currently available nucleoside analogs for antiretroviral therapy.
On the potential of laser driven isotope generation at ELI-NP for positron emission tomography

The huge progress made in the laser driven ion acceleration had open the possibility of using ions generated in high power laser interactions with solid targets for the production of medical isotopes. Indeed, lasers could provide several key features with respect to the traditional method where the target activation is produced by particle beams delivered by cyclotrons. The price and the dimensions of high power lasers are on a descendant slope and the quality of the produced ion beams is continuously increasing. However, in order to compete with cyclotrons, the average proton current intensity has to be increased for example by increasing the frequency of the laser pulses. In our contribution, we review the general ideas of the laser-based radioisotope production and we present our analysis on the potential of the medical isotope generation at ELI-NP with a focus on 18F. We use estimations of the proton beam parameters and a code implemented in Geant4 for computing the yield of the main production channel taking into account the experimental conditions available soon at ELI-NP. The obtained results are compatible with previous studies and will be verified by experiments foreseen at the future ELI-NP facility, under construction now in Magurele, Romania.
Identifying the shape collapse problem in large deformation image registration

This thesis examines and identifies the problems of shape collapse in large deformation image registration. Shape collapse occurs in image registration when a region in the moving image is transformed into a set of near zero volume in the target image space. Shape collapse may occur when the moving image has a structure that is either missing or does not sufficiently overlap the corresponding structure in the target image [6]. We state that shape collapse is a problem in image registration because it may lead to the following consequences: (1) Incorrect pointwise correspondence between different coordinate systems; (2) Incorrect automatic image segmentation; (3) Loss of functional signal. The above three disadvantages of registration with shape collapse are illustrated in detail using several examples with both real and phantom data. Shape collapse problem is common in image registration algorithms with large degrees of freedom such as many diffeomorphic image registration algorithms. This thesis proposes a shape collapse measurement algorithm to detect the regions of shape collapse after image registration in pairwise and group-wise registrations. We further compute the shape collapse for a whole population of pairwise transformations such as occurs when registering many images to a common atlas coordinate system. Experiments are presented using the SyN diffeomorphic image registration algorithm and diffeomorphic demons algorithm. We show that shape collapse exists in both of the two large deformation registration methods. We demonstrate how changing the input parameters to the SyN registration algorithm can mitigate the collapse image
Optimal Trajectory Generation in a Dynamic Multi-Body Environment Using a Pseudospectral Method

High-altitude parking orbits could provide resiliency to the military space infrastructure by providing redundancy in key assets, allowing for rapid reconstitution of underperforming satellites. When analyzing trajectories in a high-altitude regime, two-body models of Keplerian motion become less accurate since the gravitational effects of other bodies are no longer negligible. To provide a higher fidelity model of the dynamics in a high-altitude regime, a multiple-body model can be used. In the Earth-Moon system, a spacecraft operating in the high-altitude regime can be modeled with three-body dynamics. With certain simplifying assumptions, the model is called the circular-restricted three-body problem (CR3BP). The CR3BP provides unique dynamics that could be exploited to provide beneficial trajectories unavailable and unobservable in a lower-order model. The tradeoff for using this higher-order model is there is no closed-form analytical solution and the dynamics are chaotic. Methods to search for optimal trajectories within the CR3BP are analyzed to determine viability in rapid mission development. A direct orthogonal collocation pseudospectral method is utilized to generate fueland timeoptimal trajectories within the CR3BP. These results are compared to benchmarks from two-body dynamics, such as Hohmann transfers. Numerical approaches to finding optimal solutions are highly dependent on initial guesses to converge on candidate optimal solutions. To compound this issue, the chaotic dynamics in the CR3BP mean small variations in the initial conditions could lead to wildly varying trajectories. The results from the current research provide a methodology to establish a framework for rapid mission development in a dynamical environment, which may be essential to maintain space superiority and responsiveness.
