A NEW z = 0 METAGALACTIC ULTRAVIOLET BACKGROUND LIMIT

We present new integral-field spectroscopy in the outskirts of two nearby, edge-on, late-type galaxies to search for the Hα emission that is expected from the exposure of their hydrogen gas to the metagalactic ultraviolet background (UVB). Despite the sensitivity of the VIRUS-P spectrograph on the McDonald 2.7 m telescope to low surface brightness emission and the large field of view, we do not detect Hα to 5σ upper limits of 6.4 × 10−19 erg s−1 cm−2 arcsec−2 in UGC 7321 and of 25 × 10−19 erg s−1 cm−2 arcsec−2 in UGC 1281 in each of the hundreds of independent spatial elements (fibers). We fit gas distribution models from overlapping 21 cm data of H i, extrapolate one scale length beyond the H i data, and estimate predicted Hα surface brightness maps. We analyze three types of limits from the data with stacks formed from increasingly large spatial regions and compare to the model predictions: (1) single fibers, (2) convolution of the fiber grid with a Gaussian, circular kernel (10″ full width at half-maximum), and (3) the co-added spectra from a few hundred fibers over the brightest model regions. None of these methods produce a significant detection (>5σ) with the most stringent constraints on the H i photoionization rate of Γ(z = 0) < 1.7 × 10−14 s−1 in UGC 7321 and Γ(z = 0) < 14 × 10−14 s−1 in UGC 1281. The UGC 7321 limit is below previous measurement limits and also below current theoretical models. Restricting the analysis to the fibers bound by the H i data leads to a comparable limit; the limit is Γ(z = 0) < 2.3 × 10−14 s−1 in UGC 7321. We discuss how a low Lyman limit escape fraction in z ∼ 0 redshift star-forming galaxies might explain this lower than predicted UVB strength and the prospects of deeper data to make a direct detection.
Effective Classification of Colon Cancer using Resnet-18 in Comparison with Squeezenet

Aim: The work aims to find out a better way to perform colon cancer identification with the help of Resnet-18 algorithm in comparison with a Squeezenet algorithm to maximize the accuracy in finding rather than the existing method of prediction. Materials and Methods: A collection of 30 samples were picked for consideration; group 1 visualizing Resnet-18 classifier algorithm and finally group 2 is responsible for the Squeezenet algorithm. Thus G power calculation is done with a power of 80.5 and the alpha value is equivalent to 0.061. Results: When compared to the Squeezenet algorithm, the Resnet-18 classifier algorithm has attained an accuracy of 86.5060 % and 0.32754 which is somewhat greater than the existing method. ( Squeezenet algorithm attained an accuracy of 83.5433% and 0.28975) respectively. Conclusion: From the above statement it is evident that the Resnet-18 algorithm would be a better choice for predicting colon cancer and it is more effective.

Nuclei of early-type dwarf galaxies: insights from stellar populations ?

We present a comprehensive analysis of the spatially resolved stellar population properties of 26 early-type dwarf galaxies (dEs) in the Virgo cluster. Using Lick/IDS absorption line indices we derive simple stellar population (SSP) equivalent age, metallicity and [α/Fe] abundance ratio. In particular, we focus on the comparison of the stellar populations between the central nucleus and the surrounding galactic main body. The stellar populations of the nuclei are, for most dEs, significantly younger than those of the respective galactic main bodies, with an average difference of 3.5 Gyr. We find only five dEs with significantly older nuclei than their galactic main bodies. Furthermore, we observe most dE nuclei to be more metal rich compared to their host galaxies. These age and metallicity behaviours are shown by almost all dEs brighter than Mr=−17 mag. The metallicity of both nuclei and galactic main bodies correlates with the total luminosity of the dEs. However, the metallicity of the nuclei covers a larger range (+0.18 to −1.22 dex) than that of the galactic main bodies, which all have subsolar metallicity. The ages of dE nuclei show a statistically significant correlation with the local projected galaxy density within the cluster, such that younger ages are predominantly observed outside of the high-density central cluster region. The α-element abundance ratios are consistent with solar for both nuclei and galactic main bodies. We also examine the presence of radial gradients in the SSP parameters for a subset of 13 dEs (up to 1.2 kpc or 15 arcsec radius). We notice two different types of gradients, namely smooth profiles that include the nucleus, and profiles where a break occurs between the nucleus and the rest of the galaxy. Nevertheless, an overall trend of increasing age and decreasing metallicity with radius exists, consistent with earlier studies. The α-abundance ratio as function of radius is consistent with no gradient. Possible formation scenarios for the nuclei of dEs are discussed. The young and metal-enhanced population of nuclei suggests that these might have formed at later epochs, or the termination of star formation activity in the nuclei might have occurred relatively late, perhaps due to continuous infall of gas into the central potential well. Our stellar population analysis suggests that the merging of globular clusters is not an appropriate scenario for the formation of most dE nuclei, at least not for the brighter dEs. We speculate that there might be different formation processes which are responsible for the formation of dEs and their nuclei depending on their luminosity.
Managing Coopetition in Business Ecosystem - A study of the Printing Industry in Malaysia

Coopetition involves multidisciplinary actors in a competition and cooperation phenomenon simultaneously. There is a large research gap on how a coopetition process is established and managed in a business ecosystem. Through the in-depth analysis of a single printing business ecosystem in Malaysia, this paper finds coopetition is common as the way of doing business among the micro, small and medium sized firms in one industrial park growing into a popular printing ecosystem in Selangor state of Malaysia. This paper identifies the sources of coopetition, challenges faced by different firms in the same industry and the mechanism of these firms surviving in this business ecosystem. Through a case study, our findings showed that informal cooperation more likely than a structured coopetition to achieve short-term success yet a long term resilience for small medium enterprises. The possible tension in coopetition is reduced when trust and friendliness is available to maintain the business ecosystem position. The interchangeable supplier-customer relationships facilities value co-creation through exchange of resources and capabilities in the geographic, technological and market overlap business ecosystem. The paper suggests the coopetition strategy is the base strategy to build competitiveness of individual firm located in a business ecosystem.
An examination of content knowledge in formal coach education curriculum

ABSTRACT Sport coaching can be seen as an interdisciplinary endeavour, where coaches integrate multiple disciplinary knowledges to support participants achieving a variety of desirable outcomes (e.g. learn new skills, meet new people, develop greater confidence). Limited research however has considered what knowledge has been used as the basis for curricula, or how it has been structured into formal coach education courses. This is remiss because coaches not only need to learn, but need to learn something to ultimately aid their own (and others) development. Therefore, the aim of this study was to examine what content knowledge contributed to the English FA intermediate (i.e. level 2) formal coach education course, and how this knowledge was structured to form a curriculum. Data were collected using a document analysis of National Governing Body (NGB) and awarding body documents (n = 10), as well as observing two formal coach education courses, and interviewing coach developers (n = 5) that delivered those courses. A deductive thematic analysis identified three themes: (1) A Curriculum Partially Informed by Research, (2) A Strongly Classified Curriculum and (3) A Curriculum also Includes ‘Professional Knowledge’. Findings reveal the socially constructed nature of content knowledge legitimised as worth knowing in formal coach education curricula. It prompts critical consideration of what knowledge is used (or not) and how this knowledge supports learners in the dynamic and often ambiguous context of coaching. The significance of the findings move beyond the case at hand, as wider educational institutions may wish to consider what content knowledge is used, and how it is structured within their own coach education and development provisions.
THE SL2S GALAXY-SCALE LENS SAMPLE. II. COSMIC EVOLUTION OF DARK AND LUMINOUS MASS IN EARLY-TYPE GALAXIES

We present a joint gravitational lensing and stellar-dynamical analysis of 11 early-type galaxies (median deflector redshift zd = 0.5) from Strong Lenses in the Legacy Survey (SL2S). Using newly measured redshifts and stellar velocity dispersions from Keck spectroscopy with lens models from Paper I, we derive the total mass-density slope inside the Einstein radius for each of the 11 lenses. The average total density slope is found to be 〈γ′〉 = 2.16+0.09−0.09 (), with an intrinsic scatter of 0.25+0.10−0.07. We also determine the dark matter fraction for each lens within half the effective radius, Reff/2, and find the average-projected dark matter mass fraction to be 0.42+0.08−0.08 with a scatter of 0.20+0.09−0.07 for a Salpeter initial mass function. By combining the SL2S results with those from the Sloan Lens ACS Survey (median zd = 0.2) and the Lenses Structure and Dynamics Survey (median zd = 0.8), we investigate cosmic evolution of γ′ and find a mild trend ∂〈γ′〉/∂zd = −0.25+0.10−0.12. This suggests that the total density profile of massive galaxies has become slightly steeper over cosmic time. If this result is confirmed by larger samples, it would indicate that dissipative processes played some role in the growth of massive galaxies since z ∼ 1.
A Multiscale Model of Partial Melts 1: Effective Equations

[1] Developing accurate and tractable mathematical models for partially molten systems is critical for understanding the dynamics of magmatic plate boundaries as well as the geochemical evolution of the planet. Because these systems include interacting fluid and solid phases, developing such models can be challenging. The composite material of melt and solid may have emergent properties, such as permeability and compressibility that are absent in each phase alone. Previous work by several authors have used multiphase flow theory to derive macroscopic equations based on conservation principles and assumptions about interphase forces and interactions. Here we present a complementary approach using homogenization, a multiple scale theory. Our point of departure is a model of the microstructure, assumed to possess an arbitrary, but periodic, microscopic geometry of interpenetrating melt and matrix. At this scale, incompressible Stokes flow is assumed to govern both phases, with appropriate interface conditions. Homogenization systematically leads to macroscopic equations for the melt and matrix velocities, as well as the bulk parameters, permeability and bulk viscosity, without requiring ad hoc closures for interphase forces. We show that homogenization can lead to a range of macroscopic models depending on the relative contrast in melt and solid properties such as viscosity or velocity. In particular, we identify a regime that is in good agreement with previous formulations, without including their attendant assumptions. Thus, this work serves as independent verification of these models. In addition, homogenization provides a consistent machinery for computing consistent macroscopic constitutive relations such as permeability and bulk viscosity that are consistent with a given microstructure. These relations are explored numerically in the companion paper.
The Effect of Particle Concentration on Bed Particle Diffusion in Dilute Flows

In this paper, we present the simulation results of a Lagrangian particle tracking model that computes the motion of saltating sediment particles, which is considered the most important mode of bedload transport in rivers and channels. The model is one-way coupled to a validated turbulent LES-WALE (Large Eddy Simulation – Wall-Adapting Local Eddy-viscosity) channel flow, i.e., the particles do not affect the computation of the flow velocities and pressures, as suggested for dilute flows. The model addresses the particle trajectories, the collision of the particles with the bottom wall, and collision among particles. The focus of this work is placed on the effect of different particle concentrations and flow intensities (different flow shear stresses) on jump statistics and particle diffusion. Numerical results are validated with experimental laboratory data obtained from the literature for particle diameters in the range of sands. The present results indicate that, at particle concentrations up to 2%, the diffusion coefficients in the streamwise and spanwise directions, γx and γz, for the local range are nearly constants with a value close to one, corresponding to the ballistic regime. At a concentration of 4%, the largest concentration studied herein, values of γx and γz for the local range are slightly smaller, with a representative value of 0.9 regardless of flow intensities. For the intermediate regime, it was found that, on average, γx~1. 2γz with γx ranging from 0.6 to 0.85 and γz within the range 0.45–0.70. For a fixed flow intensity, both diffusion coefficients increase with the particle concentration, which is an indication of the contribution of the collision among particles to particle diffusion. For highly controlled simulation conditions, the differences in particle velocity at a given concentration may change drastically, which should translate to important fluctuations in the computation of sediment transport rates. Finally, the employed computational resources are described as a function of particle concentration. Although the number of total collisions increases linearly with the number of particles, the number of collisions per particle reaches a plateau, thus indicating that there exists an upper limiting value for the number of collisions per particle.
Clinical Study of Neurodegenerative Treatment on Glaucoma by Insulin Intravitreal Injection

Purpose: Our trail was to study insulin intravitreal injection’s (IIV) efficacity and safety to treat glaucoma neurodegeneration. Methods: Eleven subjects (11eyes) were recruited;10 patients treated in a double masked randomized sham controlled including 5 patients received one IIV injection 3UI and 5 patients received one injection of balanced salt solution(BSS) 3UI. A follow up during 168days was realized using Optical Coherence Tomography(OCT) and visual field(VF). The eleventh patient received two IIV injection without masking the injection content within one month between each injection and followed up for 877days.All the patients have a correct ocular pressure and no ocular treatment was stopped. Results: The 5 patients who received IIV revealed a swift improvement of decibel (DB), and remains stable during the first month. The average improvement was 6.62DB during 168days.The 5 patients treated with one BSS injection showed no significant improvement regaining 1. 45DB.The last patient who received two injections showed increase from 7.54DB to 17.22DB with a functional amelioration of 9. 68DB.The OCT examination showed a structural improvement during the first month, then returned to the initial value. No complication was observed during and after the treatment. Conclusion: Insulin shows not only efficacity and safety but more than that, the visual field(VF) of the patients became stable and show no deterioration in all the follow up, which confirmed that insulin act to improve the function rather than structure. it means insulin reconnect the stoma and improve the neurite outgrowth This treatment will change the evolution of this pathology and protect the glaucomatous patients against blindness.
Avoiding the Appearance of Virtue: Reactivity to Corporate Social Responsibility Ratings in an Era of Shareholder Primacy

We examine why organizations may at times decrease their performance after receiving a positive rating. We argue that in contrast to the prevailing assumption that organizations will strive for favorable ratings to achieve reputational benefits, incompatibility between a positive rating and a dominant institutional logic may cause recognized firms to question the perceived value of maintaining superior performance, thus leading them to strategically reduce their efforts on the rated dimension. Using a difference-in-differences design, we examine how companies responded to being rated as charitable organizations, an evaluation that we argue was generally perceived as incompatible with the dominant logic of shareholder maximization during the early 1990s. Our results suggest that firms that were rated as generous were more likely to decrease philanthropic contributions relative to firms that were not rated as generous. We also found this reaction to be amplified or attenuated by organizational and institutional factors that increased or decreased the saliency of the perceived incompatibility between the philanthropy rating and the dominant shareholder logic. These findings provide insights for scholarship on organizational reactivity and impression management and raise important questions for scholars and practitioners interested in improving the effectiveness of evaluation metrics as drivers of organizational performance.
THERAPEUTIC INTERVENTIONS FOR ANXIETY DISORDERS: AN INTEGRATIVE REVIEW

Backgroud: Anxiety disorders are characterized by excessive emotional responses that generate major disturbances, causing cognitive and behavioral changes and triggering somatic manifestations. Therapeutic interventions show relevance and significant results for the treatment of anxiety. Aim: To identify therapeutic interventions used in the treatment of anxiety disorders. Method: A search for publications indexed in three electronic databases was conducted from January to March 2021. Titles, abstracts, and full-text reading by two independent reviewers were analyzed and classified by level of evidence developed by the Oxford Centre for Evidence-Based Medicine. Results: It resulted in 27 studies that observed the following therapeutic interventions: Psychoeducation; Mindfulness; Evidence-Based Behavioral Therapy; Applied Relaxation; Transdiagnostic CBT; Dialectical Behavioral Therapy; Positive Activity Techniques; Individual and Group CBT; Transcendence Technique Multifaceted Spiritually Based Intervention; Unified Protocol for Transdiagnostic Treatment of Emotional Disorders; Positive Activity Intervention Protocol; and Art Therapy. Conclusions: Of the therapeutic interventions used for the treatment of anxiety disorders, Mindfulness and Psychoeducation were the interventions of greater choice among the studies, which bring large benefit and autonomy to patients, considering that the implementation of these interventions can be performed by nurses and a multidisciplinary team in primary care services, also enabling the reduction of costs to the health system.

Extragalactic relativistic jets

Extragalactic relativistic jets are engines able to carry out to large distances a huge amount of power, not only in the form of radiation, but especially in the form of kinetic energy of matter and fields. As such, they can be thought as one of the most efficient engines of Nature, perhaps even more efficient than accretion. We are starting to disclose these features through a detailed study of their properties, made possible by the analysis of the energy band where they emit most of their electromagnetic output, namely the γ–ray band. That is why the observations by the Fermi satellite and by the ground based Cherenkov telescopes are crucial to understand extragalactic jets. At the start, we believe they are magnetically dominated. And yet, on the scale where they emit most of their luminosity, their power is already in the form of kinetic energy of particles. The spectral properties of bright sources show a trend, controlled mainly by the bolometric apparent luminosity. With improved sensitivity, and the detection of weaker sources, we can explore the idea that the spectral trends are a result of the same physical quantities controlling the emission of non–jetted sources: the black hole mass and the accretion rate. This is based on recent results on sources showing a thermal component in their spectrum, besides a non–thermal continuum. That the jet power should be linked to accretion is intriguing. Most of the apparent diversity of extragalactic radio sources can then be understood on the basis of the viewing angle, controlling the relativistic Doppler boosting of the emission, the black hole mass and the accretion rate.
