description: Certain high-risk behaviours, common among adolescents today, point to the importance of implementing a comprehensive guidance and counselling program (CGCP) at the high-school level. Such programs are aimed at meeting the "whole-person" needs of all adolescents, as well as reducing risk conditions. A logical place to begin is with a comprehensive assessment of adolescents' needs. Including students in the process enables them to state their needs and stop adults from assuming that they know what students need. Moreover, such an assessment provides a database of needs from which to build a (CGCP). In this study, I investigated the nature of adolescent needs in Kenyan high schools by comparing the perspectives of students and adults (head teachers, counsellors, and teachers), and examining how students' perceptions of needs differ across gender and form (grade) levels. In addition, the infrastructure support necessary for meeting student needs was explored. Participants in the study included 917 male and female students, from Forms 1 to 4 (equivalent of Grade 9 to Grade 12 in Canada), as well as 30 adults, from 10 secondary schools selected from five districts of the Western Province of Kenya. Data were analyzed with descriptive statistics, multivariate analysis of variance (MANOVA), and content analysis. I discovered differences between student and adult groups. Adolescents' highest-priority needs were in the following clusters: instructional needs, environmental needs and counselling service needs. They also reported priority needs in these subscales: health promotion, mental and emotional health, interpersonal relationships, physical well-being, and academic skills. In contrast, adults reported highest-priority needs in these clusters: counselling service needs, instructional needs, and environment needs. Adults also reported top priority needs in the following subscales: sexuality, mental and emotional health, health promotion, personal counselling, and academic skills. Additionally, significant differences were found between gender and form (grade). A multivariate analysis of variance indicated a significant effect for both form (grade) F(45, 2626) = 2.49, p < .OJ and gender F(l5 ,884) = 3.91, p < .01, but no significant form by gender interaction F(45, 2626) = 1.02, p=44. Content analysis revealed that several barriers prevent students from receiving appropriate services. These include a lack of financial and human resources, as well as limited training available for counsellors. The results of this study support the efficacy of utilizing needs assessment results as precursor to developing and implementing a CGCP. Additionally, the results of this study have implications for the development of responsive comprehensive guidance and counselling programs in secondary/high schools, and for future research.

description: The stability of the fundamental defects of an unstretchable flat sheet is examined. This involves expanding the bending energy to second order in deformations about the defect. The modes of deformation occur as eigenstates of a fourth-order linear differential operator. Unstretchability places a global linear constraint on these modes. Conical defects with a surplus angle exhibit an infinite number of states. If this angle is below a critical value, these states possess an n-fold symmetry labeled by an integer, n \geq 2. A nonlinear stability analysis shows that the 2-fold ground state is stable, whereas excited states possess 2(n - 2) unstable modes which come in even and odd pairs.

description: The phase transition is a performance measure of the sparsity-undersampling tradeoff in compressed sensing (CS). This letter reports our first observation and evaluation of an empirical phase transition of the $\ell_1$ minimization approach to the complex valued CS (CVCS), which is positioned well above the known phase transition of the real valued CS in the phase plane. This result can be considered as an extension of the existing phase transition theory of the block-sparse CS (BSCS) based on the universality argument, since the CVCS problem does not meet the condition required by the phase transition theory of BSCS but its observed phase transition coincides with that of BSCS. Our result is obtained by applying the recently developed ONE-L1 algorithms to the empirical evaluation of the phase transition of CVCS.

description: Renoprotectors are highly demanded due to environmental nephrotoxic factors. P. longifolia leaves extract alleviating effect was assessed in nephritic-induced rats by whole body shot dose of γ-radiation. Many biomarkers were detected using several assays. Renohistopathological examinations were performed. Moreover, the extract phytoconstituents were identified using spectroscopic analysis. In-vitro anti-inflammatory activity of some compounds was examined using histamine release assay. Post-irradiation treatment with the extract significantly ameliorated all elevated biomarker levels. Creatinine and urea were adjusted, TGF-β/Smad signaling was suppressed causing down-regulation to microRNA-21. Nitric oxide, reactive oxygen species, glutathione and kidney injury molecule-1 were normalized in comparison with the γ-irradiated group. The renohistopathological analysis was consistent with the biochemical study. Phytochemical analysis resulted in the isolation of two diterpenoids (γ-methoxybutenolide clerodane diterpene and 16(R/S)-hydroxycleroda-3,13-dien-16,15-olide-2-one), aporphine alkaloid (anonaine) and flavonol (kaempferol-3-O-rutinoside). The latter two showed moderate anti-histaminic activities. Our results indicated that P. longifolia reduced oxidative stress and nephropathy in rats due to its anti-inflammatory principles.

description: The Le Chatelier principle states that physical equilibria are not only stable, but they also resist external perturbations via short-time negative-feedback mechanisms: a perturbation induces processes tending to diminish its results. The principle has deep roots, e.g., in thermodynamics it is closely related to the second law and the positivity of the entropy production. Here we study the applicability of the Le Chatelier principle to evolutionary game theory, i.e., to perturbations of a Nash equilibrium within the replicator dynamics. We show that the principle can be reformulated as a majorization relation. This defines a stability notion that generalizes the concept of evolutionary stability. We determine criteria for a Nash equilibrium to satisfy the Le Chatelier principle and relate them to mutualistic interactions (game-theoretical anticoordination) showing in which sense mutualistic replicators can be more stable than (say) competing ones. There are globally stable Nash equilibria, where the Le Chatelier principle is violated even locally: in contrast to the thermodynamic equilibrium a Nash equilibrium can amplify small perturbations, though both this type of equilibria satisfy the detailed balance condition.

description: Journalists have been using data in their stories for as long as the profession has existed. A revolution in computing in the 20th century created opportunities for data integration into investigations, as journalists began to bring technology into their work. In the 21st century, a revolution in connectivity is leading the media toward new horizons. The Internet, cloud computing, agile development, mobile devices, and open source software have transformed the practice of journalism, leading to the emergence of a new term: data journalism. Although journalists have been using data in their stories for as long as they have been engaged in reporting, data journalism is more than traditional journalism with more data. Decades after early pioneers successfully applied computer-assisted reporting and social science to investigative journalism, journalists are creating news apps and interactive features that help people understand data, explore it, and act upon the insights derived from it. New business models are emerging in which data is a raw material for profit, impact, and insight, co-created with an audience that was formerly reduced to passive consumption. Journalists around the world are grappling with the excitement and the challenge of telling compelling stories by harnessing the vast quantity of data that our increasingly networked lives, devices, businesses, and governments produce every day. While the potential of data journalism is immense, the pitfalls and challenges to its adoption throughout the media are similarly significant, from digital literacy to competition for scarce resources in newsrooms. Global threats to press freedom, digital security, and limited access to data create difficult working conditions for journalists in many countries. A combination of peer-to-peer learning, mentorship, online training, open data initiatives, and new programs at journalism schools rising to the challenge, however, offer reasons to be optimistic about more journalists learning to treat data as a source.

description: Presented at the Protections 2016: 2nd international seminar on dam protection against overtopping: concrete dams, embankment dams, levees, tailings dams held on 7th-9th September, 2016, at Colorado State University in Fort Collins, Colorado, USA. The increasing demand for dam and levee safety and flood protection has motivated new research and advancements and a greater need for cost-effective measures in overtopping protection as a solution for overtopping concerns at levees and dams. This seminar will bring together leading experts from practice, research, development, and implementation for two days of knowledge exchange followed by a technical tour of the Colorado State University Hydraulic Laboratory with overtopping flume and wave simulator. This seminar will focus on: Critical issues related to levees and dams; New developments and advanced tools; Overtopping protection systems; System design and performance; Applications and innovative solutions; Case histories of overtopping events; Physical modeling techniques and recent studies; and Numerical modeling methods.
description: Includes bibliographical references.
description: Over the past 26 years numerous embankment dams and earth-cut spillways in the United States have been armored using Articulating Concrete Blocks (ACBs) to provide erosion protection. Several dams and spillways armored with ACBs have been overtopped and performed satisfactorily with overtopping flow depths and velocities approaching 4 feet and 30 feet per second, respectively. Over the same period, some ACB overtopping applications have failed and others have experienced damage requiring maintenance to make the ACB system functional again. Much has been learned about what works and what does not work. Of the ACB installations that have failed or experienced damage, the underlying issues have been attributed to one of several potential failure modes that may not have been understood or adequately addressed during the design. The purpose of this paper is to share information on several recent ACB embankment armoring and spillway armoring failures, and to describe the specific failure modes associated with these incidents. Suggestions for incorporating design features to address these potential failure modes are also provided. This information is important for engineers to consider during their designs, and for regulators reviewing ACB armoring designs, so that future failures and unnecessary damage resulting in costly maintenance can be prevented.

description: Simultaneous Localization and Mapping (SLAM) by robots is a difficult problem: n01sy odometry combined with noisy range sensor measurements lead to quick accumulation of error. \i\Then the robots need to communicate to each other or to a base station to share their maps, the problem is also compounded by wireless network issues. Most research to date ignores or oversimplifies the network model when simulating SLAM. This thesis uses network simulation to get more accurate communications description. Estimating map quality in SLAM research has been traditionally done subjectively by humans. This thesis tries to quantify the SLAM map quality. The main contribution of this research is to determine the effect of the wireless communication channel on map building by using realistic network simulations tied with SLAJVI. Another contribution is to suggest using Hausdorff distance as a map quality measure.

At the leading order, the process takes place through quark-loop box and triangle diagrams and it is ultraviolate finite. We report the results for the LHC. We also discuss the issues of anomaly and decoupling of heavy quarks in the amplitude.

description: The aim of this research is to provide a comprehensive overview of how U.S. news outlets are using mobile push alerts to reach their audiences. Its objectives are to better understand how and why news outlets are using mobile push alerts, the decision-making process and workflows behind their use, how metrics inform strategy, and the major challenges presented by push alerts and how outlets have tackled them. The study intends to provide a detailed understanding of the use of mobile push alerts by news outlets of all sizes and backgrounds. This research took part in two phases. The first involved a quantitative content analysis examining when and how news outlets send push alerts. For this part of the research we analyzed 2,578 push alerts—2,085 from thirty-one iOS apps and 492 from fourteen Apple News channels. These alerts were collected over the three-week period between June 19 and July 9, 2017 using an iPhone 6 running iOS 10. They were coded manually using a coding scheme devised to address our research questions. The second part of the research involved twenty-three, semi-structured interviews with audience managers, mobile editors, and product managers from a range of U.S. news outlets. These interviews focused on strategy and workflows, addressing issues such as how and why different outlets decide what to push, how and why they approach Apple News differently, their objectives for push alerts, how metrics are used to inform strategy, and major challenges that push alerts present. This report combines the findings from both phases of the research to provide a detailed overview of how U.S. newsrooms are approaching mobile push alerts.

description: This essay is part survey and part manifesto, one that concerns itself with the practice of journalism and the practices of journalists in the United States. It is not, however, about “the future of the news industry,” both because much of that future is already here and because there is no such thing as the news industry anymore. If you wanted to sum up the past decade of the news ecosystem in a single phrase, it might be this: Everybody suddenly got a lot more freedom. The newsmakers, the advertisers, the startups, and, especially, the people formerly known as the audience have all been given new freedom to communicate, narrowly and broadly, outside the old strictures of the broadcast and publishing models. The past 15 years have seen an explosion of new tools and techniques, and, more importantly, new assumptions and expectations, and these changes have wrecked the old clarity. Many of the changes talked about in the last decade as part of the future landscape of journalism have already taken place; much of journalism’s imagined future is now its lived-in present. (As William Gibson noted long ago, “The future is already here. It’s just unevenly distributed.”) Our goal is to write about what has already happened and what is happening today, and what we can learn from it, rather than engaging in much speculation.

description: Fiscal sponsorship is an American term used to describe partnerships between registered charitable organizations and non-registered groups or individuals. A generally accepted practice in the Unites States, it is now emerging in Canada in response to trends in the voluntary sector such as: challenges to the definition of what is charitable, a lengthy registration process, lack of capacity within the sector, and citizen engagement through community development practices. This study explores fiscal sponsorship from two perspectives. Through interviews with fiscal sponsorship practitioners, it provides a description of the practice. The practice is then considered from a legal perspective. The legal interviews provide an understanding of how current policy and guidelines can be interpreted and applied to fiscal sponsorship practice as described by the practitioners. These opposing viewpoints highlight the gaps between policy and practice. This study provides guidelines of practice and policy recommendations to address these gaps.

Data of an early experiment and the recent Crystal Ball experiment at BNL are included in the analysis with the c.m. energy from 1550 to 1676 MeV. Our results clearly support the existence of a $Σ$ resonance with $J^P={1\over 2}^+$, mass near 1633 MeV, and width about 120 MeV, which confirms the 3-star $Σ(1660) 1/2^+$ in PDG. Meanwhile, our results do not support the existence of the 2-star $Σ(1620){1\over 2}^-$ in PDG. The analysis results for the parameters of the relevant $Σ$ resonances and couplings are presented.

Social movements--Political aspects

description: Coverage of any breaking news event today often includes footage captured by eyewitnesses and uploaded to the social web. This has changed how journalists and news organizations not only report and produce news, but also how they engage with sources and audiences. In addition to social media platforms such as Twitter and Facebook, chat apps such as WhatsApp and WeChat are a rapidly growing source of information about newsworthy events and an essential link between participants and reporters covering those events. To look at how journalists at major news organizations use chat apps for newsgathering during political unrest, the authors focus on a case study of foreign correspondents based in Hong Kong and China during and since the 2014 Umbrella Movement Hong Kong protests. Political unrest in Hong Kong and China often centers around civic rights and government corruption. The Umbrella Movement involved large-scale, sit-in street protests, rejecting proposed changes to Hong Kong’s electoral laws and demanding voting rights for all Hong Kong citizens. Through a combination of observation and interviews with foreign correspondents, this report explores technology’s implications for reporting political unrest: how and why the protestors and official sources used chat apps, and the ways foreign reporters used chat apps (which are typically closed platforms) for newsgathering, internal coordination, and information sharing.
Magnetic resonance imaging lesion count as a surrogate endpoint in relapsing-remitting multiple sclerosis clinical trials
Creators: name: Qin, Lang
Publisher: name: University of British Columbia
Year: 2011

description: The count of active lesions based on magnetic resonance imaging (MRI) is often used as a potential surrogate endpoint in phase 2 clinical trials for relapsing-remitting multiple sclerosis (RRMS) patients. However, this surrogacy relationship has not been completely validated. In this report, we study whether at the trial level, the MRI lesion count is a good surrogate endpoint for the relapse rate, the usual clinical endpoint for RRMS clinical trials. Two different approaches to assess this surrogacy relationship are applied to the dataset used by Sormani et al. [1] (SBRCMB) which contains the summary results from 23 randomized, placebo-controlled clinical trials in RRMS. The SBRCMB approach uses simple linear regression with weighted least squares estimation, while our more comprehensive approach develops a detailed model for the endpoints and the treatment effects to take into account estimation errors and the correlated contrasts. Both approaches are based only on the summary results from each clinical trial. The shortcomings of the SBRCMB approach are discussed and the results from the two approaches are compared. Both approaches show that the MRI lesion count is a good surrogate endpoint, while our more comprehensive approach shows a nearly perfect surrogacy relationship. When the estimated surrogacy relationship is used to predict the true treatment effect on the clinical endpoint for the trials in the SBRCBM dataset, the approaches give similar point predictions, but the approximate 95% prediction intervals from the comprehensive approach are generally shorter. In practice, the estimated surrogacy relationship based on the comprehensive approach can give a precise prediction for the true treatment effect on the clinical endpoint if the treatment displays a large effect on the surrogate endpoint, but may otherwise lead to an inconclusive result.

description: We study cosmological models described by a single real scalar field. We work within the first-order framework, and we show how the first-order equations simplify the investigation, leading to a direct search of twinlike theories. The procedure is used to introduce distinct models that support the same first-order equations, with the very same energy densities and pressure in flat spacetime. The presence of curvature forbids the construction of twinlike models in the cosmological scenario here investigated.

description: We construct SO(2,1) x SO(3)-invariant half-BPS solutions in six-dimensional (0,4) supergravity with m tensor multiplets. The space-time manifold of each one of these solutions consists of an AdS_2 x S^2 warped over a Riemann surface Sigma with boundary. The most general local solution is parametrized by one real harmonic function, and m+2 holomorphic functions which are subject to a quadratic constraint and a hermitian inequality, both of which are manifestly SO(2,m) invariant. Imposing suitable conditions on these harmonic and holomorphic functions, we construct globally regular supergravity solutions with N distinct AdS_3 x S^3 asymptotic regions and contractible Sigma. These solutions have an intricate moduli space, whose dimension equals 2(m+1)N -m-2 and matches the counting of three-form charge vectors and un-attracted scalars of the tensor multiplet. Exact explicit formulas for all supergravity fields are obtained in terms of the moduli. Our solutions give the near-horizon geometries for junctions of N self-dual strings in six dimensions, and are holographic duals to CFTs defined on N half-planes which share a common interface line. For m=5, the solutions lift to quarter-BPS solutions for six-dimensional (4,4) supergravity.

description: The Mt Nerone area hosts a Jurassic-Cretaceous Pelagic Carbonate Platform (PCP)-basin succession in the Umbria-Marche Domain (Central Italy). Despite being studied thoroughly on sedimentological and geological aspects, wide-spectrum palaeocological studies are currently missing for this peculiar setting. While several studies on the invertebrate fauna of PCP system are available, the vertebrate fauna remained for a long time mostly unknown. Recently a renewed interest has been directed to vertebrate remains of the region. To date, an articulated dentition and some other tooth fragments of hybodont sharks and neoginglymodian actinopterygians have been described from the Jurassic of the Mt Nerone area. These taxa indicate the existence of diverse durophagous ecological niches available for durophagous fauna in the PCP system, linked to the abundant hard-shelled invertebrate fauna inhabiting the structural highs. In the present contribution we report and describe remains of neoselachians Synechodontiformes from five localities of the Mt Nerone area. The new material, represented by several isolated teeth and referred to as Sphenodus spp., testifies an additional trophic level for the Jurassic palaeoecology in the Umbria-Marche Domain, throwing new light on the peculiar PCP-basin ecosystem.

description: We perform an explicit one-loop calculation for the gravitational contributions to the two-, three- and four-point gauge Green's functions with paying attention to the quadratic divergences. It is shown for the first time in the diagrammatic calculation that the Slavnov-Taylor identities are preserved even if the quantum graviton effects are included at one-loop level, such a conclusion is independent of the choice of regularization schemes. We also present a regularization scheme independent calculation based on the gauge condition independent background field framework of Vilkovisky-DeWitt's effective action with focusing on both the quadratic divergence and quartic divergence that is not discussed before. With the harmonic gauge condition, the results computed by using the traditional background field method can consistently be recovered from the Vilkovisky-DeWitt's effective action approach by simply taking a limiting case, and are found to be the same as the ones yielded by the diagrammatic calculation. As a consequence, in all the calculations, the symmetry-preserving and divergent-behavior-preserving loop regularization method can consistently lead to a nontrivial gravitational contribution to the gauge coupling constant with an asymptotic free power-law running at one loop near the Planck scale.

description: Were studied classical oscillations of background metric in the multidimensional anisotropic model of Kazner in the de-Sitter stage. Obtained dependence of fluctuations on dimension of space-time with infinite expansion. Stability of the model could be achieved when number of space-like dimensions equals or more then four. Were calculated contributions to the density of "vacuum energy", that are providing by proper oscillations of background metric and compared with contribution of cosmological arising of particles due to expansion. As it turned out, contribution of gravitational oscillation of metric into density of "vacuum energy" should play significant role in the de-Sitter stage.

First, we illustrate how a dotplot is calculated. Then, we introduce FlexiDot and compare it to other software. We explain how it works as well as its features. Subsequently, we exemplify the use of FlexiDot: Our showcases include tandem repeats (such as satellite and ribosomal DNA), transposable elements (such as LTR retrotransposons), and proteins with repeated domains (filamin proteins, nucleotide-binding leucine-rich repeat proteins).

description: Across the industry, we are seeing a wide-sweeping trend of newsrooms uprooting themselves: A.H. Belo, Gannett, MediaNews, Advance, Gate-House, Cox--small newspapers and large ones alike are listing their newsrooms for sale. Everyone from the private owners of the Syracuse Media Group, to the owners behind the Boston Herald, has moved buildings. This is a countrywide, size-wise trend1 that begs the questions: Is this just one more slap in the face for newsrooms now at their lowest staffing levels since the 1970s? Is it one more sign in line with the circulation declines and revenue slides that signals the inability of newsrooms to get their financial models right? Or perhaps, instead, there is another story to tell here, one embedded with the opportunity to think about a physical move as a way to shed the past and look forward to the future of news through tactile readjustment.

description: Presented at the Protections 2016: 2nd international seminar on dam protection against overtopping: concrete dams, embankment dams, levees, tailings dams held on 7th-9th September, 2016, at Colorado State University in Fort Collins, Colorado, USA. The increasing demand for dam and levee safety and flood protection has motivated new research and advancements and a greater need for cost-effective measures in overtopping protection as a solution for overtopping concerns at levees and dams. This seminar will bring together leading experts from practice, research, development, and implementation for two days of knowledge exchange followed by a technical tour of the Colorado State University Hydraulic Laboratory with overtopping flume and wave simulator. This seminar will focus on: Critical issues related to levees and dams; New developments and advanced tools; Overtopping protection systems; System design and performance; Applications and innovative solutions; Case histories of overtopping events; Physical modeling techniques and recent studies; and Numerical modeling methods.

description: The technology of wedge shaped blocks (WSB) for spillways has had a rising development through the last forty years, and has proved its reliability for practical applications with spillways executed during the last decade. Ongoing additional research aims to complete the understanding of the hydraulic behavior, improve current design criteria and make this technology available to practitioners, in order to consider this type of spillway together with the conventional alternatives when designing an embankment dam spillway. A summary is here shown of recent research performed by the consortium formed by the research organizations: Research Group in Dam Safety (SERPA) of the Technical University of Madrid (UPM) and the International Center for Numerical Methods in Engineering (CIMNE) and the company PREHORQUISA. Even though the experimental campaign has not been completed, some preliminary conclusions can be addressed about the developed pressures along the block tread and the leakage flow from the joints among blocks and the drainage holes.

description: In the testable Flipped $SU(5)\times U(1)_X$ model with TeV-scale vector-like particles from F-theory model building dubbed as the flip SU(5) model, we study the vector-like quark contributions to B physics processes, including the quark mass spectra, Feynman rules, new operators and Wilson coefficients, etc. We focus on the implications of the vector-like quark mass scale on B physics. We find that there exists the $\bar{s}bZ$ interaction at tree level, and the Yukawa interactions are changed. Interestingly, different from many previous models, the effects of vector-like quarks on rare B decays such as $B\to X_sγ$ and $B\to X_s\ell^+\ell^-$ do not decouple in some viable parameter space, especially when the vector-like quark masses are comparable to the charged Higgs boson mass. Under the constraints from $B\to X_sγ$ and $\ B\to X_s\ell^+\ell^-$, the latest measurement for $B_s\to μ^+μ^-$ can be explained naturally, and the branching ratio of $B_s\to \ell^+\ell^-γ$ can be up to $(4\sim5)\times10^{-8}$. The non-decouling effects are much more predictable and thus the \fsu5 model may be tested in the near future experiments.

description: Too often we tend to hear one single narrative about the state of newspapers in the United States. The newspaper industry is not one sector. While there are considerable variances between the myriad of outlets—whether national titles, major metros, dailies in large towns, alt weeklies, publications in rural communities, ethnic press, and so on—a major challenge for anyone trying to make sense of industry data is its aggregated nature. It’s nearly impossible to deduce trends or characteristics at a more granular level. The story of local newspapers with circulations below 50,000, or what we call “small-market newspapers,” tends to get overlooked due to the narrative dominance of larger players. However, small-market publications represent a major cohort that we as a community of researchers know very little about, and a community of practitioners that too often—we were told—knows little about itself. Our study seeks to help redress this recent imbalance. We embarked on our research with a relatively simple yet ambitious research question: How are small-market newspapers responding to digital disruption? From the data collected in our research, we also strove to report on the future of small-market newspapers by asking: How can small-market newspapers best prepare for the future? Our research findings are based on interviews with fifty-three experts from across the publishing industry, academia, and foundations with a strong interest in the local news landscape. So as to make a fair assessment of the topic’s placement against a wider news background, we did not limit ourselves just to those with immediate connection to small-market newspapers. From these conversations and our own analysis, seven key themes emerged.

description: We investigate bounds on the strength of the primordial magnetic field (PMF) from the cosmic microwave background (CMB) bispectra of the intensity (temperature) modes induced from the auto- and cross-correlated bispectra of the scalar and tensor components of the PMF anisotropic stress. At first, we construct a general formula for the CMB intensity and polarization bispectra from PMFs composed of any type of perturbation. Then we derive an approximate expression which traces the exact shape of the CMB bispectrum in order to reduce the computation time with respect to a large number of the multipole configurations, and also show that the non-Gaussian structure coming from PMFs is classified as the local-type configuration. Computing the signal-to-noise ratio on the basis of the approximate formula with the information of the instrumental noises and resolutions, we find expected upper bounds on the magnetic field strength, when the magnetic spectrum is nearly scale invariant ($n_B = -2.9$), smoothed on $1 {\rm Mpc}$ scale at 95% confidence level from the WMAP and PLANCK experiments as $B_{1 \rm Mpc} < 4.0 - 6.7 {\rm nG}$ and $3.8 - 6.5 {\rm nG}$, respectively, depending on the energy scale of the magnetic field production from $10^{14} {\rm GeV}$ to $10^3 {\rm GeV}$. Our new consequences imply slight overestimations by the previous rough discussions.
