description: IRIS is the co-ordinating body of a UK science eInfrastructure and is a collaboration between UKRI-STFC, its resource providers and representatives from the science activities themselves. We document the progress of an ongoing project to build a security policy trust framework suitable for use across the IRIS community. The EU H2020-funded AARC projects addressed the challenges involved in integrating identity services across different infrastructures, thereby allowing research communities to securely share data and resources. The result of this work hinged around the AARC Blueprint Architecture allowing federations of services and identity providers to connect via one or more proxies. In addition to AARC technical architecture documents and guidelines, a policy team created a set of template policies published as the AARC Policy Development Kit (PDK), which following the completion of the AARC projects will find a long term home under the SCI working group of the WISE community. Derived from existing practice, the PDK aims to assist in efficiently bootstrapping Research Infrastructures in the operation of an authentication and authorisation infrastructure in line with the AARC Blueprint Architecture, making them accessible to researchers in an easy and secure fashion. We document the experience gained by the IRIS community in adopting component policies of the PDK to form a policy foundation for resource sharing, access and trust. The lack of such an established trust framework hindered the early growth of IRIS activities and the promise of a 'ready-made' framework of templates, based on current best practice recommendations for federated environments, available for use made the PDK an obvious place to start. Starting with an examination of stakeholder requirements and discussion of how to map these to the PDK templates, we describe the current status of the process to create a sub-set of policies to form a trust framework for a national infrastructure collaboration.

description: For a large class of finite-range quantum spin models with half-integer spins, we prove that uniqueness of the ground state implies the existence of a low-lying excited state. For systems of linear size L, of arbitrary finite dimension, we obtain an upper bound on the excitation energy (i.e., the gap above the ground state) of the form (C\log L)/L. This result can be regarded as a multi-dimensional Lieb-Schultz-Mattis theorem and provides a rigorous proof of a recent result by Hastings.

Roles for PLD2 in growth factor-mediated signal transduction in EL4 lymphoma cells
Creators: name: Chahal, Manpreet Singh
Publisher: name: Washington State University
Year: 2008
Subjects: Cellular signal transduction

description: Phospholipase D2 (PLD2) generates phosphatidic acid through hydrolysis of phosphatidylcholine. Murine lymphoma EL4 cells lacking endogenous PLD2 expression present a unique model to elucidate the role of PLD2 in signal transduction. Stable overexpression of active PLD2 in EL4 cells does not effect basal proliferation, although expression of inactive PLD2 decreases basal proliferation. Active PLD2 leads to increased basal activation of Akt. Overexpression of active PLD2 leads to enhanced migration in response to serum, however a significant decrease in migration occurs in cells expressing inactive PLD2, as compared to parental cells. Active PLD2 enhances invasion in response to serum, while the opposite is observed with inactive PLD2. Both parental EL4 cells and PLD2 transfectants express endogenous epidermal growth factor receptor (EGFR). Levels of EGFR protein are increased in cells expressing active PLD2, as compared to parental cells. EGF stimulates proliferation of EL4 cells expressing active PLD2, but not parental cells or cells expressing inactive PLD2. PLD2 knockdown (via siRNA) reduces EGF-mediated proliferation in C5 cells to control levels. EGF-mediated proliferation and migration in cells expressing active PLD2 is mediated by the PI3K/Akt pathway. EGF-induced invasion is enhanced in cells expressing active PLD2, as compared to parental cells. In order to elucidate genes modulated by PLD2, we used V7 and C5 cells in a microarray experiment. We identified 102 genes differentially expressed 2 to 16.5 fold in response to overexpressed PLD2. SOCS2, a protein with an inverse relationship with the EGFR, was selected as a gene of interest. Differential expression of SOCS2 was validated at the protein level, showing that overexpression of PLD2 leads to down-regulation of SOCS2. Overall, the results of this study show that PLD2 enhances Akt activation, migration, and invasion in EL4 cells. PLD2 leads to increased EGFR expression, and acts in concert with EGFR to enhance mitogenesis and invasion. The results indicate that inactive PLD2 exerts inhibitory effects. The microarray study contributes to a broader understanding of the cellular role of PLD2.

description: In this paper, based on the notion of pseudomode framework introduced by Garraway in [Phys. Rev. A 55, 2290 (1997)], we propose a mechanism for enhancing the efficiency of excitation energy transport in a spin channel which is in contact with a Lorentzian reservoir, through the inclusion of other similar auxiliary spin chains into the reservoir. To this aim, a Lindblad-type master equation for the dynamics of the transport process is provided on the basis of pseudomode approach. It is figured out that increasing the number of auxiliary chains in the reservoir enhances the efficiency of transport or equivalently, rises the population of the reaction center attached to the end of the channel. Moreover, it is interesting to note that the mechanism has better efficiency for the channels with longer lengths.

description: Oligomers of styrene have been identified in polystyrene (PS) polymer samples intended for food packaging. Such oligomers contribute to nonintentionally added substances (NIAS) that may migrate into food or food simulants and therefore have to be assessed for the potential risk to health. No oligomers larger than dimers and trimers of styrene have been found to be present in PS. Some in vivo and in vitro information indicative of an endocrine activity for some specific oligomers suggest concerns for their potential for endocrine disruption in humans. Data on endocrine activity available from in vitro and in vivo screening approaches and from non-guideline studies in experimental animals were evaluated. The different test methods were classified according to the OECD Conceptual Framework for Testing and Assessment of Endocrine Disruptors (OECD) and the ranking system of Borgert et al. proposed in 2014. The quality and reliability of each study is further assessed by professional judgment. The integration of the total information supports the conclusion that neither specific oligomers, nor their mixtures, potentially migrating into food are endocrine disruptors according to the definition of EFSA and WHO/IPCS.

description: Our study aimed to evaluate the effects of nano and chelated Fe fertilization on nutrient and heavy metals uptake and their translocation from soil to root, stem, leaf, and fruits of fresh market tomatoes (Solanum Lycopersicon, cv. Sunbrite). A completely randomized design in a factorial experiment, with two Fe sources (nano vs. chelated) applied at 0 (control), 10, 20, and 40 mg/L via drip-irrigated plasticulture, was conducted. Nutrient and heavy metals concentrations in soil, water, tomato roots, stems, leaves, and fruits were determined. Soil had higher K, Fe, Ca, Mg, P, and Mn but lower Ni, Cd, and Cr concentrations. The P, K, Fe, Cu, Mn, and Na concentrations in the roots were significantly affected by both nano and chelated Fe fertilization; however, without following a consistent pattern. Averaged across the Fe treatments, K, Ca, Mg, Fe, and P that translocated from the soil were dominated in the roots, stems, and leaves. The nutrient translocation order, from roots to fruits in response to Fe fertilization, was nano Fe (40%) > chelated Fe (37%) > control (23%). Based on the treatment index values calculated across treatments, it is evident that Fe fertilization plays a pivotal role in nutrient uptake and translocation. The use of chelated Fe at a concentration of 20 mg/L had a pronounced effect on improving the nutritional quality of the tomatoes and, by extension, their associated public health benefits. In conclusion, the chelated Fe (20 mg/L) stands out as the most preferable and effective Fe fertilization for tomatoes.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We implement lattice QCD using the Fortran 90 language. We have designed machine independent modules that define fields (gauge, fermions, scalars, etc...) and have defined overloaded operators for all possible operations between fields, matrices and numbers. With these modules it is very simple to write QCD programs. We have also created a useful compression standard for storing the lattice configurations, a parallel implementation of the random generators, an assignment that does not require temporaries, and a machine independent precision definition. We have tested our program on parallel and single processor supercomputers obtaining excellent performances.

Microscopic theory of refractive index applied to metamaterials: Effective current response tensor corresponding to standard relation $n^2 = \varepsilon_{\mathrm{eff}} μ_{\mathrm{eff}}$

description: In this article, we first derive the wavevector- and frequency-dependent, microscopic current response tensor which corresponds to the "macroscopic" ansatz $\vec D = \varepsilon_0 \varepsilon_{\mathrm{eff}} \vec E$ and $\vec B = μ_0 μ_{\mathrm{eff}} \vec H$ with wavevector- and frequency-independent, "effective" material constants $\varepsilon_{\mathrm{eff}}$ and $μ_{\mathrm{eff}}$. We then deduce the electromagnetic and optical properties of this effective material model by employing exact, microscopic response relations. In particular, we argue that for recovering the standard relation $n^2 = \varepsilon_{\mathrm{eff}} μ_{\mathrm{eff}}$ between the refractive index and the effective material constants, it is imperative to start from the microscopic wave equation in terms of the transverse dielectric function, $\varepsilon_{\mathrm{T}}(\vec k, ω) = 0$. On the phenomenological side, our result is especially relevant for metamaterials research, which draws directly on the standard relation for the refractive index in terms of effective material constants. Since for a wide class of materials the current response tensor can be calculated from first principles and compared to the model expression derived here, this work also paves the way for a systematic search for new metamaterials.

Photoelectron spectroscopy studies on novel doped clusters

Publisher: name: Washington State University
Year: 2009
Subjects: Microclusters -- Properties

description: Atomic clusters consisting of a few to few hundred atoms exhibit dramatically size-dependent chemical and physical properties, forming the foundation for nanoscience and nano-technology. Doping clusters with a foreign atom offers an additional dimensionality to fine tune their structures and properties. This dissertation describes photoelectron spectroscopic investigations on three series of single-atom-doped clusters, with a focus on their size-dependent geometric and electronic structures. In doping the small planar gold clusters (<= Au12- ), as presented in chapter three, we found that Agand Cu- doping have little influence on the overall structures of the parent gold clusters, except for MAu10- where an earlier 2D-3D structural transition was observed for the doped species as compared to the pure gold clusters; whereas the group-14 atoms (Si, Ge, Sn) form strong covalent bond with gold, whose doping significantly distort the planar geometries of the small gold clusters. In chapter four, we focus on doping the golden buckyball Au16- with different atoms. We concluded that the nature of dopant-Au interactions is the key factor in determining the structures of the doped golden cage clusters. We have shown that Cu, Ag, Zn, and In atom can be doped inside the golden buckyball with little structural distortion, while Si-, Ge- and Sn-doping lead to exohedral structures due to the strong dopant-Au local interactions. Transition metal atoms Fe, Co and Ni can also be doped inside Au16- to form magnetic golden cages. These doped clusters form a new class of endohedral golden buckyballs with tailored properties, analogous to the endohedral fullerenes. Chapter five presents the studies on a series of carbon-boron clusters: CB7 -, CB6 2-, CB6 -, C2B5 -, and CB8. These clusters were previously predicted to be novel species containing hypercoordinate carbon atom in planar geometries. However, our studies show that all these clusters adopt low symmetry structures and carbon avoids hypercoordination sites in these species. Thus, in contrast to the theoretical predictions, we conclude that none of these clusters is viable for designing hypercoordinate planar carbon.

description: Objective. Endothelial function, including the nitric oxide (NO)-pathway, has previously been extensively investigated in heart failure (HF). In contrast, studies are lacking on the NO pathway after heart transplantation (HT). We therefore investigated substances in the NO pathway prior to and after HT in relation to hemodynamic parameters. Design. 12 patients (median age 50.0 yrs, 2 females), heart transplanted between June 2012 and February 2014, evaluated at our hemodynamic lab, at rest, prior to HT, as well as four weeks and six months after HT were included. All patients had normal left ventricular function post-operatively and none had post-operative pulmonary hypertension or acute cellular rejection requiring therapy at the evaluations. Plasma concentrations of ADMA, SDMA, L-Arginine, L-Ornithine and L-Citrulline were analyzed at each evaluation. Results. In comparison to controls, the plasma L-Arginine concentration was low and ADMA high in HF patients, resulting in low L-Arginine/ADMA-ratio pre-HT. Already four weeks after HT L-Arginine was normalized whereas ADMA remained high. Consequently the L-Arginine/ADMA-ratio improved, but did not normalize. The biomarkers remained unchanged at the six-month evaluation and the L-Arginine/ADMA-ratio correlated inversely to pulmonary vascular resistance (PVR) six months post-HT. Conclusions. Plasma L-Arginine concentrations normalize after HT. However, as ADMA is unchanged, the L-Arginine/ADMA-ratio remained low and correlated inversely to PVR. Together these findings suggest that (i) the L-Arginine/ADMA-ratio may be an indicator of pulmonary vascular tone after HT, and that (ii) NO-dependent endothelial function is partly restored after HT. Considering the good postoperative outcome, the biomarker levels may be considered “normal” after HT.

description: Submillimeter Array 1.3mm line and continuum observations toward the young massive star-forming region IRAS18182-1433 are presented. The data are complemented with short-spacing CO(2-1) observations and SiO(1-0) data from the VLA. Multiple massive outflows emanate from the mm continuum peak. The CO(2-1) data reveal a quadrupolar outflow system consisting of two outflows inclined by \~90 degrees. One outflow exhibits a cone-like red-shifted morphology with a jet-like blue-shifted counterpart where a blue counter-cone can only be tentatively identified. The SiO(1-0) data suggest the presence of a third outflow. Analyzing the 12CO/13CO line ratios indicates decreasing CO line opacities with increasing velocities. The other seven detected molecular species - also high-density tracers like CH3CN, CH3OH, HCOOCH3 - are all ~1-2'' offset from the mm continuum peak, but spatially associated with a strong molecular outflow peak and a cm emission feature indicative of a thermal jet. This spatial displacement between the molecular lines and the mm continuum emission could be either due to an unresolved sub-source at the position of the cm feature, or the outflow/jet itself alters the chemistry of the core enhancing the molecular abundances toward that region. A temperature estimate based on the CH3CN(12_k-11_k) lines suggests temperatures of the order 150K. A velocity analysis of the high-density tracing molecules reveals that at the given spatial resolution none of them shows any coherent velocity structure which would be consistent with a rotating disk. We discuss this lack of rotation signatures and attribute it to intrinsic difficulties to observationally isolate massive accretion disks from the surrounding dense gas envelopes and the molecular outflows.

Sexual selection and reproductive allocation in prothonotary warblers
Creators: name: Beck, Michelle Lee
Publisher: name: Washington State University
Year: 2010
Subjects: Prothonotary warbler -- Sexual behavior

description: Historically, studies of sexual selection have focused on males, but it is becoming increasingly obvious that sexual selection acts on females as well. In male songbirds, plumage coloration is a sexually selected trait that functions in female mate choice and in competition among males for resources. In these species, females also display plumage coloration that could be acted on by sexual selection. Additionally, life history trade-offs such as the trade-off between parental and mating effort should be examined in both sexes given the connection to sexual selection. I examined plumage coloration in male and female prothonotary warblers to determine if it is a signal of quality used in mate choice and a signal of competitive ability. I also determined how males and females made trade-offs between parental and mating effort, as measured by their ability to produce colorful plumage after a costly reproductive event. I found no evidence for assortative pairing by plumage coloration, but males and females that were more pure yellow in plumage color initiated nests earlier in the season. Females with more pure yellow coloration had higher reproductive success at the first nest of the year. Males with more pure yellow coloration had larger clutches laid for them and extra-pair males were more pure yellow than the male that they cuckolded. Males and females that were more pure yellow in plumage coloration were able to obtain nest sites that were unlikely to be depredated. Females rearing an experimentally enlarged brood increased the amount and frequency of food delivery to nestlings whereas males did not. Females that reared an enlarged brood were unlikely to have a second brood and their future plumage coloration was unaffected by the manipulation. Males that reared an enlarged brood sired a smaller proportion of the offspring in their second brood and produced plumage coloration that was less pure yellow the next year. These results provide evidence that plumage coloration is a sexually selected trait in female as well as male prothonotary warblers, that it is condition-dependent in males, and that the costs of rearing an enlarged brood are sex specific.

Femoral neck bone mineral density (BMD), age plus femoral neck BMD T score, and three externally generated fracture risk tools had similar accuracy to identify older men who developed osteoporotic fractures. Risk tools with femoral neck BMD performed better than those without BMD. The externally developed risk tools were poorly calibrated.IntroductionWe compared the performance of fracture risk assessment tools in older men, accounting for competing risks including mortality.MethodsA comparative ROC curve analysis assessed the ability of the QFracture, FRAX® and Garvan fracture risk tools, and femoral neck bone mineral density (BMD) T score with or without age to identify incident fracture in community-dwelling men aged 65 years or older (N = 4994) without hip or clinical vertebral fracture or antifracture treatment at baseline.ResultsAmong risk tools calculated with BMD, the discriminative ability to identify men with incident hip fracture was similar for FRAX (AUC 0.77, 95% CI 0.73, 0.81), the Garvan tool (AUC 0.78, 95% CI 0.74, 0.82), age plus femoral neck BMD T score (AUC 0.79, 95% CI 0.75, 0.83), and femoral neck BMD T score alone (AUC 0.76, 95% CI 0.72, 0.81). Among risk tools calculated without BMD, the discriminative ability to identify hip fracture was similar for QFracture (AUC 0.69, 95% CI 0.66, 0.73), FRAX (AUC 0.70, 95% CI 0.66, 0.73), and the Garvan tool (AUC 0.71, 95% CI 0.67, 0.74). Correlated ROC curve analyses revealed better diagnostic accuracy for risk scores calculated with BMD compared with QFracture (P < 0.0001). Calibration was good for the internally generated BMD T score predictor with or without age and poor for the externally developed risk tools.ConclusionIn untreated older men without fragility fractures at baseline, an age plus femoral neck BMD T score classifier identified men with incident hip fracture as accurately as more complicated fracture risk scores.

description: We study the dynamics of diffusion processes acting on directed multiplex networks, i.e., coupled multilayer networks where at least one layer consists of a directed graph. We reveal that directed multiplex networks may exhibit a faster diffusion at an intermediate degree of coupling than when the two layers are fully coupled. We use three simple multiplex examples and a real-world topology to illustrate the characteristics of the directed dynamics that give rise to a regime in which an optimal coupling exists. Given the ubiquity of both directed and multilayer networks in nature, our results could have important implications for the dynamics of multilevel complex systems towards optimality.

description: Background: Cocoa and dark chocolate (DC) have been reported to be effective for health promotion; however the exact effect of cocoa/DC on anthropometric measures have not been yet defined. Methods: A comprehensive search to identify randomized clinical trials investigating the impact of cocoa/DC on body weight, body mass index (BMI) and waist circumference (WC) was performed up to December 2017. A meta-analysis of eligible studies was performed using random effects model to estimate pooled effect size. Fractional polynominal modeling was used to explore dose-response relationships. Results: A total of 35 RCTs investigated the effects of cocoa/DC on weight, BMI and WC were included. Meta-analysis did not suggest any significant effect of cocoa/DC supplementation on body weight (−0.108 kg, 95% CI −0.262, 0.046 P = 0.168), BMI (−0.014 kg/m2 95% CI −0.105, 0.077, P: 0.759,) and WC (0.025 cm 95% CI −0.083, 0.129, P = 0.640). Subgroup analysis revealed that that weight and BMI were reduced with cocoa/DC supplementation ≥ 30 g chocolate per day in trials between 4-8 weeks. Cocoa/DC consumption resulted in WC reduction in non-linear fashion (r = 0.042, P-nonlinearity = 0.008).Conclusion: Cocoa/DC supplementation does not reduce anthropometric measures significantly. However subgroup analysis regarding dose (≥ 30 g/day) and duration (between 4 to 8 weeks) revealed significant reduction of body weight and BMI.

At the End of the Chain: The Implications of the EU Deforestation Regulation on Smallholders in the Indonesian Palm Oil Trade

description: As supply chains become increasingly globalized, unilaterally imposed regulations raise tensions between national sovereignty and their extraterritorial consequences on economic development. While the European Union has the right to regulate its supply chains, such policies can have severe implications for smallholders in commodity-producing countries who are often underrepresented in the policy-making process. Through a case study on the impact of the EU Deforestation Regulation (EUDR) on Indonesia’s palm oil industry, this paper explores how supply chain regulations can reinforce existing inequalities in transnational trade at the industry and international level. By analyzing the responses and actions taken by industry stakeholders and government actors following the introduction of the EUDR in 2023 – drawing on secondary interviews and reports – this study reveals how unilateral supply chain regulations can disproportionately impede smallholder market access and deepen asymmetries between the Global North and commodity-producing nations.

description: Using a projection-based decoupling of the Fokker-Planck equation, control strategies that allow to speed up the convergence to the stationary distribution are investigated. By means of an operator theoretic framework for a bilinear control system, two different feedback control laws are proposed. Projected Riccati and Lyapunov equations are derived and properties of the associated solutions are given. The well-posedness of the closed loop systems is shown and local and global stabilization results, respectively, are obtained. An essential tool in the construction of the controls is the choice of appropriate control shape functions. Results for a two dimensional double well potential illustrate the theoretical findings in a numerical setup.
Alignment of the BESIII end cap TOF system
Creators: name: Shengsen Sun
name: Wen, Shuo Pin
Publisher: name: Zenodo
Year: 2019

description: The end cap time-of-flight (ETOF) at Beijing Spectrometer (BESIII) was upgraded with multi-gap resistive plate chamber technology in order to improve the particle identification capability. The accurate knowledge of the detector real misalignment is important for getting close to the designed time resolution and the expected reconstruction efficiency of the end cap time-of-flight system. The incident position of charged track is extrapolated from multilayer drift chamber to the end cap time-of-flight detector based on the ideal geometry. The raw measured time difference between the two readout channels of one strip could be used to derive an incident position of the charged track using the transmission velocity of the signal in the readout strip, this position is obtained from the response of the detector, without any geometric hypothesis. A software is developed using the comparison between these two positions to provide the spatial position difference between the real detector and the ideal location. The procedure developed towards the alignment and the geometry is updated based on the result of the alignment. The time resolution and reconstruction achieved in recent years are also described in this talk.
On hypergeometric series reductions from integral representations, the Kampe de Feriet function, and elsewhere

description: Single variable hypergeometric functions pFq arise in connection with the power series solution of the Schrodinger equation or in the summation of perturbation expansions in quantum mechanics. For these applications, it is of interest to obtain analytic expressions, and we present the reduction of a number of cases of pFp and p+1F_p, mainly for p=2 and p=3. These and related series have additional applications in quantum and statistical physics and chemistry.

description: We systematically develop the metric aspects of nonassociative differential geometry tailored to the parabolic phase space model of constant locally non-geometric closed string vacua, and use it to construct preliminary steps towards a nonassociative theory of gravity on spacetime. We obtain explicit expressions for the torsion, curvature, Ricci tensor and Levi-Civita connection in nonassociative Riemannian geometry on phase space, and write down Einstein field equations. We apply this formalism to construct R-flux corrections to the Ricci tensor on spacetime, and comment on the potential implications of these structures in non-geometric string theory and double field theory.

description: This thesis proposes two new coding schemes that jointly encode a set of messages and enable receivers which have known part of the transmitted messages to retrieve the remaining unknown messages at the target bit error rate with lower energy requirement than those receivers without. The proposed schemes provide a new approach of code construction and the performance analysis in this thesis also provides a deeper understanding of how to effectively design coding schemes for the scenario where receivers may have known some of the transmitted messages a priori.
Multi-frequency scatter broadening evolution of pulsars - I

description: We present multi-wavelength scatter broadening observations of 47 pulsars, made with the Giant Metre-wave Radio Telescope (GMRT), Ooty Radio Telescope (ORT) and Long Wavelength Array (LWA). The GMRT observations have been made in the phased array mode at 148, 234, and 610 MHz and the ORT observations at 327 MHz. The LWA data sets have been obtained from the LWA pulsar data archive. The broadening of each pulsar as a function of observing frequency provides the frequency scaling index, $α$. The estimations of $α$ have been obtained for 39 pulsars, which include entirely new estimates for 31 pulsars. This study increases the total sample of pulsars available with $α$ estimates by $\sim$50\%. The overall distribution of $α$ with the dispersion measure (DM) of pulsar shows interesting variations, which are consistent with the earlier studies. However, for a given value of DM a range of $α$ values are observed, indicating the characteristic turbulence along each line of sight. For each pulsar, the estimated level of turbulence, $C^{2}_{n_e}$, has also been compared with $α$ and DM. Additionally, we compare the distribution of $α$ with the theoretically predicated model to infer the general characteristics of the ionized interstellar medium (ISM). Nearly 65\% of the pulsars show a flatter index (i.e., $α< 4.4$) than that is expected from the Kolmogorov turbulence model. Moreover, the group of pulsars having flatter index is typically associated with an enhanced value of $C^{2}_{n_e}$ than those with steeper index.

description: High resolution spectra with UVES/VLT of SN 1987A from December 2000 until November 2005 show a number of high ionization lines from gas with velocities of roughly 350 km/s, emerging from the shocked gas formed by the ejecta-ring collision. These include coronal lines from [Fe X], [Fe XI] and [Fe XIV] which have increased by a factor of about 20 during the observed period. The evolution of the lines is similar to that of the soft X-rays, indicating that they arise in the same component. The line ratios are consistent with those expected from radiative shocks with velocity 310-390 km/s, corresponding to a shock temperature of (1.6-2.5) x 10^6 K. A fraction of the coronal emission may, however, originate in higher velocity adiabatic shocks.

Measurement of $τ$ polarisation in $Z/γ^{*}\rightarrowττ$ decays in proton-proton collisions at $\sqrt{s}=8$ TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: arXiv
Year: 2017
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: This paper presents a measurement of the polarisation of $τ$ leptons produced in $Z/γ^{*}\rightarrowττ$ decays which is performed with a dataset of proton-proton collisions at $\sqrt{s}=8$ TeV, corresponding to an integrated luminosity of 20.2 fb$^{-1}$ recorded with the ATLAS detector at the LHC in 2012. The $Z/γ^{*}\rightarrowττ$ decays are reconstructed from a hadronically decaying $τ$ lepton with a single charged particle in the final state, accompanied by a $τ$ lepton that decays leptonically. The $τ$ polarisation is inferred from the relative fraction of energy carried by charged and neutral hadrons in the hadronic $τ$ decays. The polarisation is measured in a fiducial region that corresponds to the kinematic region accessible to this analysis. The $τ$ polarisation extracted over the full phase space within the $Z/γ^{*}$ mass range of 66$ < m_{Z/γ^{*}} < $ 116 GeV is found to be $P_τ =-0.14 \pm 0.02 (\text{stat}) \pm 0.04 (\text{syst})$. It is in agreement with the Standard Model prediction of $P_τ =-0.1517 \pm 0.0019$, which is obtained from the ALPGEN event generator interfaced with the PYTHIA 6 parton shower modelling and the TAUOLA $τ$ decay library.
