Square of the degree of coherence and dispersion-induced pulse broadening in a fiber-optic transmission

: We describe a method for measuring optical pulse broadening with continuous wave beam emitted from a low-coherence source. A two-beam interferometer composed of nondispersive and dispersive arms makes it possible to obtain the dispersion-induced pulse broadening. Experiments are carried out using a standard single-mode ﬁ ber and a two-mode ﬁ ber in the 1560 nm-wavelength region. As a result, the square of the degree of coherence, | γ | 2 , well re ﬂ ects the dispersion-induced pulse broadening for an unchirped Gaussian pulse. The theoretically derived relationship between these two physical phenomena well re ﬂ ects the experimentally obtained results. Chromatic dispersion values obtained by the method are in good agreement with those obtained by the alternative method. The salient feature of the present method is clearly shown.
The Role of Transglutaminase 2 in the Radioresistance of Melanoma Cells

Transglutaminase 2 (TG2) is a protein expressed in many tissues that exerts numerous, sometimes contradictory, intra- and extracellular functions, under both physiological and pathophysiological conditions. In the context of tumor progression, it has been found to be involved in cell adhesion, DNA repair mechanisms, induction of apoptosis, and mesenchymal transdifferentiation, among others. Here, we hypothesized that TG2 also contributes to the radioresistance of two human melanoma cell lines, A375 and MeWo, which can be seen to differ in their basal TG2 biosynthesis by examining their proliferation and clonal expansion after irradiation. For this purpose, cellular TG2 biosynthesis and TG2 activity were modulated by transfection-induced overexpression or TG2 knock-out and application of TG2-selective inhibitors. Proliferation and clonal expansion of TG2-overexpressing cells was not enhanced over wildtype cells, suggesting that increased TG2 biosynthesis does not further enhance the radioresistance of melanoma cells. Conversely, TG2 knock-out in A375 cells reduced their proliferation, as well as clonal and spheroidal expansion after irradiation, which indicates a contribution of TG2 to the radioresistance of melanoma cells. Since TG1, TG3, and partly also, TG6 biosynthesis was detectable in A375 and MeWo cells, it can be assumed that these other members of the TG family may exert a partially compensatory effect.
Pengaruh Debt Tax Shield dan Efektif Tax Rate Terhadap Struktur Modal Pada Perusahaan Advertising Printing Media

Capital structure is the ratio between debt and equity. Capital structure is useful for measuring the proportion of debt and equity used as a source of company funding. This study aims to examine the Debt tax shield, and the Effective Tax Rate on the capital structure of Advertising Printing Media companies listed on the Indonesia Stock Exchange. The research approach used in this research is associative. The sample used by purposive sampling is 12 companies for the years 2016-2019. Data analysis techniques used are descriptive statistics, multiple linear regression test panel data model, hypothesis testing (t-test and F-test) and the coefficient of determination test. The results of this study indicate that partially the size of the debt tax shield has an effect on the capital structure and the effective tax rate has no effect on the capital structure. Then Debt tax share and Effective tax rate simultaneously affect the capital structure. Thus, decision makers can use these ratios as a tool of consideration in making policies in the corporate tax system.

In conclusion, companies that published sustainability reports based on the GRI standards presented the reports that were complete, informative, and comprable. Accordingly, companies can increase the disclosure of CSR activities especially in term of waste management, to meet the needs of stakeholders.
Tropical and Subtropical Pacific Sources of the Asymmetric El Niño‐La Niña Decay and Their Future Changes

El Niños (EN) are known to decay more rapidly, while La Niñas (LN) tend to decay more slowly. Observational analyses and coupled model experiments are conducted to show that sea surface temperature (SST) anomalies over the subtropical northeastern Pacific (SNEP) and equatorial western Pacific (EWP) are key factors to determine the decay pace of the EN and LN and their asymmetry. In the present climate the LN produces larger cold SST anomalies over the regions than the warm SST anomalies produced by the EN. The magnitude difference over the SNEP and EWP helps to slow down the LN decay via subtropical footprinting and tropical thermocline variation mechanisms, respectively. Coupled Model Intercomparison Project Phase 6 models project the magnitude differences of SNEP SST anomalies between EN and LN to reduce in the future warming world, causing the asymmetric EN‐LN decay to weaken.
Optimization of a permanent magnet traction motor for electric vehicle

AUXILEC has developed a 45 kW permanent magnet (PM) traction motor for electric vehicle. In the frame of the VE2000 program, which is carried out in common with RENAULT, an optimization of the motor is realised by the mean of a close collaboration between the car maker and the motor supplier. The aim of this optimization, which proceeds from the specificity of the flux weakening of the PM motor, is to adjust the motor specification through a detailed analysis of the vehicle required performances and to obtain in consequence a gain for the motor cost, and at the same time a gain for performances such as the dimensions, weight and efficiency. The first part of the paper describes the initial PM motor which was developed according to another vehicle specification; the main features of this motor are explained including a general description, the characteristics, the efficiency, the thermal load, and a short description of the pilot line which was developed for the production of this motor. The second part of the paper explains how the optimization of the motor was carried out and presents the positive expected results. The detailed analysis of the vehicle dynamic and efficiency requested performances, and the analysis of the initial motor thermal and efficiency specific characteristics, show that the initial motor is oversized for the real need and that an optimization can be done, which can lead to simultaneous gains without reducing the dynamic performances of the vehicle. The active length is taken as the only modification parameter and the consequences of its reduction are explained. The consequences on the weight, dimensions and cost are presented, and results of simulations present the gain for the vehicle range.
Antennes reconfigurables en diagramme de rayonnement à base de surfaces sélectives de fréquence / Reconfigurable Radiation Pattern Antennas Based on Frequency Selective Surfaces.

Reconfigurable antennas have recently formed a popular research topic. They are attracting the interest of many industry professionals. This is basically due to the growing demands for more functionality while occupying the same or even smaller physical volume. Using various antennas for wireless applications is no longer effective because having several antennas take too much space. Reconfigurable antennas are the best solution to provide a better performance in terms of flexibility, efficiency and combination of several electromagnetic spectrum applications. Frequency selective surfaces are exploited in many communication applications, especially in designing reconfigurable antennas due to their ability to control the electromagnetic field. A frequency selective surface is an important figure concept in reconfigurable antenna structures and has developed rapidly due to their unique properties in suppressing the surface wave propagation. The main topic of this research is to design new reconfigurable radiation pattern antennas with enhanced performance by using switchable frequency selective surfaces. The antenna consists of a central radiating source surrounded by switchable frequency selective surface unit cells to give the antenna beam, shaping capability to scan 360 degree in the azimuth plane. Novel switchable frequency selective surface unit cells with various structures are designed and their characteristics are compared in both the reflective and transparent states. The reconfigurable response is the basic concept in the antenna design. This is achieved by adding PIN diodes to the lines that will connect or disconnect the unit cells and transform the frequency selective surface to be either a reflective or a transparent surface. As a consequence, switching the frequency selective surface PIN diodes leads to control the antenna beam direction. In this thesis, two novel reconfigurable antennas with frequency selective surface unit cells are presented, each antenna works at a different frequency band. The switchable frequency selective surface utilized in the proposed antennas operates at different frequency bands. The research topic in this thesis includes investigations and techniques to increase the bandwidth and improve the radiation characteristics of the reconfigurable antennas by using new switchable frequency selective surface unit cells. Experimental results show the preference of the proposed antennas over those presented in the literature. Thus, two new reconfigurable antennas are implemented and their enhanced performances in terms of bandwidth are proven.
Expecting parents’ use of digital sources in preparation for parenthood in a digitalised society – a systematic review

Background In today's society, people are experiencing the rapid development of digitalisation. Expecting parents may have difficulties evaluating the information online; they are not always sure which sources of information are trustworthy, and this exacerbates their feelings of anxiety. More research is needed to broaden the knowledge about how their use of digital sources may influence their health. Question The focus of this study was to explore expecting parents’ use of digital sources and how this influences their health during pregnancy. Methods A systematic review covered the thematic analysis of 39 articles. Findings The analysis resulted in the following theme: The digitalised society involves both opportunities and challenges, and expecting parents express a need for a variety of digital sources to improve their health, and sub-themes: Digital sources could promote parents’ health and well-being in a digitalised society; Consuming digital health information facilitates understanding, different feelings and social connections; and A variety of digital sources may facilitate parental identification and adaption to parenthood. Conclusion Different digital sources in our digitalised society mean access to information and opportunities to extend social connections for expecting parents. This can promote their ability to understand and adapt to parenthood, as well as to improve their health and well-being and make the parental transition. However, professional support during face-to-face consultations cannot always be exchanged to digital sources. It is important to base digital sources devoted to expecting parents and digitalisation overall on multi-sectorial collaborations and coordination between different organisations and the digital sources they provide.

Effect of Curcumin Mediated Photodynamic Technology on Salmonella typhimurium Biofilm and Its Bactericidal Mechanism and Application in Milk

The inactivation effect of curcumin-mediated photodynamic technology (PDT), a novel alternative non-thermal technique, on Salmonella typhimurium ( S. typhimurium ) biofilm and its preliminary bactericidal mechanism and application in milk were investigated. Biofilm formed from S. typhimurium ATCC 14028 was incubated with the photosensitizer curcumin, followed by exposure to blue laser (λ max 450 nm) for testing antibiofilm effect. Planktonic S. typhimurium was taken for exploring the possible bactericidal mechanism. After curcumin-PDT treatment, the damages of bacterial DNA and protein were observed by agarose gel electrophoresis and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) respectively, and the morphology change was visualized by scanning electron microscopy (SEM). Confocal laser scanning microscopy (CLSM) was employed to test bacterial membrane permeability change. Bacterial viability decreased significantly when curcumin concentration and illumination time increased. Curcumin (80 μ M) combined with blue light (200 mW/cm 2 ) illumination for 200 mW inactivated more than 2 lg/(CFU/mL) damage, protein degradation, and morphological change of PDT-treated S. typhimurium were observed. Curcumin-PDT treatment gained less bactericidal effect on S. typhimurium in milk and the inactivation efficacy was related to type of milk, curcumin concentration, illuminated liquid level and liquid transmittance. Therefore, curcumin-PDT is a promising method or assistance to control foodborne
Finite control-set model predictive current control of five-phase permanent-magnet synchronous machine based on virtual voltage vectors

This study proposes a finite control-set model predictive current control (FCS-MPCC) scheme based on virtual voltage vectors for five-phase permanent magnet synchronous machines, which aims to reduce the low-order harmonic components of stator currents. In addition, comparing with traditional FCS-MPCC algorithms, the proposed algorithm retains fast control dynamic response and brings several other benefits: such as smaller burden of calculation, approximate constant switching frequency in entire speed operation range and lower current harmonics, especially for three-order harmonics. Furthermore, the one-step delay compensate solution of the proposed FCS-MPCC scheme in digital-controller implementation is presented. Finally, a series of computer simulation and hardware-in-loop (HIL) experimental tests are adopted to compare the performances of the proposed FCS-MPCC and two traditional FCS-MPCC schemes. Simulation and HIL experimental results have verified the validity and effectiveness of the proposed FCS-MPCC scheme using virtual voltage vectors.
Kerala Bird Atlas 2015–20: features, outcomes and implications of a citizen-science project

Citizen-science driven exercises (e.g. bird surveys) and online platforms (e.g. eBird) provide voluminous data on bird occurrence. However, the semi-structured nature of their data collection makes it difficult to compare bird distribution across space and time. Bird atlases are based on standardized surveys and describe the distribution of bird species over a predefined region and have fewer biases, and thus are better suited for use in research. The recently concluded Kerala Bird Atlas (henceforth KBA) is Asia’s largest bird atlas in terms of geographical extent, sampling effort and species coverage. The entire state of Kerala was systematically surveyed twice a year during 2015–20 and over 0.3 million records of 380 species from 25,000 checklists were aggregated. The dataset was filtered and various metrics were estimated. A total of 915 cells were laid out for systematic surveys, of which 888 were surveyed in either or both the seasons – dry season (January–March) and wet season (July–September); 27 cells could not be surveyed in either of the seasons due to logistical constraints. However, this variation in sampling effort had a minimal effect on survey completeness. The slope of the species accumulation curve suggested nearcomplete species sampling in over 70% of the cells. After eliminating nocturnal and pelagic species, data from 361 species were analysed. Species count was higher in the dry season than in the wet season. Species richness (count) and evenness were higher in the northern and central districts than in the southern districts. High elevation regions of the southern Western Ghats were the largest contiguous areas lacking sufficient sampling. We found that most of the endemics were concentrated in the Western Ghats, but threatened species were as likely to occur along the coasts as in the Ghats. The KBA dataset is a valuable resource for testing various ecological hypotheses and suggesting science-backed conservation measures. KBA model could be replicated for similar atlases in other states or biogeographic regions of India.
A MULTIPLE TIMESCALE NETWORK MODEL OF INTRACELLULAR
CALCIUM CONCENTRATIONS IN COUPLED NEURONS: INSIGHTS FROM
ROM SIMULATIONS.

In [16], the authors analyzed the synchronization features between two identical 3D slow-fast oscillators, symmetrically coupled, built as an extension of the FitzHugh–Nagumo dynamics generating Mixed-Mode Oscillations. The third variable, which is slow, represents the intracellular calcium concentration in neurons. Here, we consider an extension of this model in two directions. First, we consider heterogeneity among cells and analyze the coupling of two oscillators with different values for one parameter tuning the intrinsic frequency. We identify new patterns of antiphasic synchronization, with non-trivial signatures and that exhibit a Devil’s Staircase phenomenon in transitions. Second, we introduce a network of N cells divided into two clusters: the coupling between neurons in each cluster is excitatory, while between the two clusters is inhibitory. Such system models the interactions between neurons tending to synchronization in two subpopulations inhibiting each other, like ipsi- and contra-lateral motoneurons assemblies. To perform the numerical simulations when N is large, as an initial step towards the network analysis, we consider Reduced Order Models to save computational costs. We present the numerical reduction results in a network of 100 cells. To validate the numerical reduction method, we compare the outputs and CPU times obtained in different cases.
A Hybrid Approach to Discover Entity Synonyms

Major part of the current web information retrieval involves the fulfilment of people’s daily needs based upon finding entities involving movies, events, persons, places, concepts etc. The trend has been the outcome of the tremendous amount of precise and detailed information available on the web making it possible to retrieve the precisely targeted information involving specific instance of a particular domain called Entity. The major problem in the entity-based search is the diversity of the name references made to the same instance of the same domain by the content creators and the searchers. These diversified references are known as entity synonyms. The problem is that they cannot be handled through lexical resources. This paper takes into account the previous works carried out in this direction and proposes an advanced mechanism that creates a richer set of entity synonyms than the previous approaches. The work also proposes an index to assess the quality of entity synonyms so generated which is further normalized and fuzzified for implementing automated search.
