description: We present a detailed analysis of the complex soft X-ray spectrum of NGC 4151 measured by the RGS instruments aboard XMM-Newton. The XMM-Newton RGS spectra demonstrate that the soft X-ray emission is extremely rich in X-ray emission lines and radiative recombination continua (RRC), with no clear evidence for any underlying continuum emission. Line emission, and the associated RRC, are clearly detected from hydrogen-like and helium-like ionization states of neon, oxygen, nitrogen and carbon. The measured lines are blueshifted with a velocity of between ~100-1000 km/s, with respect to the systemic velocity of NGC 4151, approximately consistent with the outflow velocities of the absorption lines observed in the UV, suggestive of an origin for the UV and soft X-ray emission in the same material. Plasma diagnostics imply a range of electron temperatures of ~1-5x10^4 K and electron densities of between 10^8-10^10 cm^-3. The soft X-ray spectrum of NGC 4151 is extremely similar to that of NGC 1068, suggesting that the soft X-ray excesses observed in many Seyfert galaxies may be composed of similar emission features. Modelling the RGS spectra in terms of emission from photoionized and photoexcited gas in an ionization cone reproduces all of the hydrogen-like and helium-like emission features observed in the soft X-ray spectrum of NGC 4151 in detail and confirms the correspondence between the soft X-ray emission in NGC 4151 and NGC 1068.

description: We have reformulated the quantum Monte Carlo (QMC) technique so that a large part of the calculation scales linearly with the number of atoms. The reformulation is related to a recent alternative proposal for achieving linear-scaling QMC, based on maximally localized Wannier orbitals (MLWO), but has the advantage of greater simplicity. The technique we propose draws on methods recently developed for linear-scaling density functional theory. We report tests of the new technique on the insulator MgO, and show that its linear-scaling performance is somewhat better than that achieved by the MLWO approach. Implications for the application of QMC to large complex systems are pointed out.

description: BACKGROUND: The home environment is thought to influence children's weight trajectories. However, few studies utilise composite measures of the home environment to examine associations with energy balance behaviours and weight. The present study aimed to adapt and update a comprehensive measure of the obesogenic home environment previously developed for pre-schoolers, and explore associations with school-aged children's energy balance behaviours and weight. METHODS: Families from the Gemini cohort (n = 149) completed the Home Environment Interview (HEI) via telephone when their children were 12 years old. The HEI comprises four composite scores: one for each domain (food, activity and media) of the environment, as well as a score for the overall obesogenic home environment. The primary caregiver also reported each child's height and weight (using standard scales and height charts), diet, physical activity and sedentary screen-based behaviours. A test-retest sample (n = 20) of caregivers completed the HEI a second time, 7-14 days after the initial interview, to establish test-retest reliability. RESULTS: Children (n = 298) living in 'higher-risk' home environments (a 1 unit increase in the HEI obesogenic risk score) were less likely to consume fruits (OR; 95% CI = 0.40; 0.26-0.61, p

description: Using the AdS/CFT correspondence we study the holographic principle and the CFT/FRW relations in the near-horizon AdS(5)xS(5) geometry with a probe D3-brane playing the role of the boundary to this space. The motion of the probe D3-brane in the bulk, induces a cosmological evolution on the brane. As the brane crosses the horizon of the bulk black hole, it probes the holography of the dual CFT. We test the holographic principle and we find corrections to CFT/FRW relations in various physical cases: for radially moving, spinning and electrically charged D3-brane and for a NS/NS B-field in the bulk.

description: BACKGROUND: Restrictions on face-to-face contact, due to COVID-19, led to a rapid adoption of technology to remotely deliver cardiac rehabilitation (CR). Some technologies, including Active+me, were used without knowing their benefits. We assessed changes in patient activation measure (PAM) in patients participating in routine CR, using Active+me. We also investigated changes in PAM among low, moderate, and high risk patients, changes in cardiovascular risk factors, and explored patient and healthcare professional experiences of using Active+me. METHODS: Patients received standard CR education and an exercise prescription. Active+me was used to monitor patient health, progress towards goals, and provide additional lifestyle support. Patients accessed Active+me through a smart-device application which synchronised to telemetry enabled scales, blood pressure monitors, pulse oximeter, and activity trackers. Changes in PAM score following CR were calculated. Sub-group analysis was conducted on patients at high, moderate, and low risk of exercise induced cardiovascular events. Qualitative interviews explored the acceptability of Active+me. RESULTS: Forty-six patients were recruited (Age: 60.4 ± 10.9 years; BMI: 27.9 ± 5.0 kg.m2; 78.3% male). PAM scores increased from 65.5 (range: 51.0 to 100.0) to 70.2 (range: 40.7 to 100.0; P = 0.039). PAM scores of high risk patients increased from 61.9 (range: 53.0 to 91.0) to 75.0 (range: 58.1 to 100.0; P = 0.044). The PAM scores of moderate and low risk patients did not change. Resting systolic blood pressure decreased from 125 mmHg (95% CI: 120 to 130 mmHg) to 119 mmHg (95% CI: 115 to 122 mmHg; P = 0.023) and waist circumference measurements decreased from 92.8 cm (95% CI: 82.6 to 102.9 cm) to 85.3 cm (95% CI 79.1 to 96.2 cm; P = 0.026). Self-reported physical activity levels increased from 1557.5 MET-minutes (range: 245.0 to 5355.0 MET-minutes) to 3363.2 MET-minutes (range: 105.0 to 12,360.0 MET-minutes; P

description: If instantons are introduced into the MIT bag model in such a way that bag radii are allowed to vary, the MIT bag interior can accommodate instanton density which is by an order of magnitude larger than in the case when the radii are fixed (although it is still significantly smaller than in the nonperturbative QCD vacuum). The instanton contribution to baryon mass shifts is also correspondingly larger. The instanton-induced part of the scalar strangeness of the nucleon MIT bag is an order of magnitude larger than found previously, within the linearized approximation. The decrease of the model radii (which is associated with the increase of the instanton density) is very favorable from the standpoint of nuclear physics.

description: Bounds on the anomalous magnetic moment and the electric dipole moment of the $τ$-neutrino are calculated through the reaction $e^{+}e^{-}\to ν\bar νγ$ at the $Z_1$-pole, and in the framework of a left-right symmetric model. The results are based on the recent data reported by the L3 Collaboration at CERN LEP. We find that the bounds are almost independent of the mixing angle $ϕ$ of the model in the allowed experimental range for this parameter. In addition, the analytical and numerical results for the cross-section have never been reported in the literature before.

description: In this paper we conduct a Monte Carlo study to determine the power of Pearson’s overall goodness-of-fit test as well as the “Pearson analog” tests (see Anderson (1994)) to detect rejections due to shifts in variance, skewness and kurtosis, as we vary the number and location of the partition points. Simulations are conducted for small and moderate sample sizes. While it is generally recommended that to improve the power of the goodness-of-fit test the partition points are equiprobable, we find that power can be improved by the use of non-equiprobable partitions.

description: We present a new approach to constructing inflationary models in closed universes. Conformal embedding of closed-universe models in a de Sitter background suggests a quantisation condition on the available conformal time. This condition implies that the universe is closed at no greater than the 10% level. When a massive scalar field is introduced to drive an inflationary phase this figure is reduced to closure at nearer the 1% level. In order to enforce the constraint on the available conformal time we need to consider conditions in the universe before the onset of inflation. A formal series around the initial singularity is constructed, which rests on a pair of dimensionless, scale-invariant parameters. For physically-acceptable models we find that both parameters are of order unity, so no fine tuning is required, except in the mass of the scalar field. For typical values of the input parameters we predict the observed values of the cosmological parameters, including the magnitude of the cosmological constant. The model produces a very good fit to the most recent CMBR data. The primordial curvature spectrum predicts the low-l fall-off in the CMB power spectrum observed by WMAP. The spectrum also predicts a fall-off in the matter spectrum at high k, relative to a power law. A further prediction of our model is a large tensor mode component, with r~0.2.

First, the results corroborate the …ndings of the Fund that both devaluation and credit restraint are e¤ective in addressing the balance of payment issues facing Ghana. Second, the direction and time pattern of the e¤ects of these two policy experiments are di¤erent. Third, further depreciation of the domestic currency is unfavourable to the cause of curbing in‡ation in Ghana. It rather leads to price increases and is a source of fueling in‡ation, and could lead to a spiral of in‡ation through the agitation for higher wages by employees.
Photometric Variability Among the Brightest Asymptotic Giant Branch Stars Near the Center of M32

description: Deep K' images with 0.1 arcsec angular resolution, obtained with ALTAIR+NIRI on Gemini North, are used to investigate photometric variablity among the brightest asymptotic giant branch (AGB) stars in the central regions of M32. Based on a comparison with brightnesses obtained from the K-band data discussed by Davidge et al. (2000, ApJ, 545, L89), it is concluded that (1) at least 60% of bright AGB stars near the center of M32 are photometrically variable, and (2) the amplitudes of the light variations are similar to those of long period variables in the Galactic bulge. We do not find evidence for a population of large amplitude variables, like those detected by IRAS in the Galactic bulge. The technique discussed here may prove useful for conducting an initial reconnaisance of photometric variability among AGB stars in spheroids in the Virgo cluster and beyond, where the required long exposure times may restrict observations to only a few epochs.

title: Cellular mechanisms that regulate the endogenous mono-ADP-ribosylation of the G protein βγ subunit.
Creators: name: Dani, Nadia
Publisher: name: The Open University
Year: 2006

description: Mono-ADP-ribosylation is a reversible, post-translational modification of cellular proteins that has been implicated in regulation of signal transduction, muscle cell differentiation, and protein trafficking and secretion. The reaction is catalysed by mono-ADP-ribosyltransferases that transfer a single ADP-ribose moiety from p-NAD+ to a specific amino-acid of acceptor proteins. An ADP-ribosylation reaction occurs in intact cells on the p subunit of heterotrimeric G proteins that is carried out by an arginine- specific, plasma-membrane-associated, mono-ADP-ribosyltransferase. This modification is reversed by a cytosolic ADP-ribosylhydrolase that regenerates native Py dimer by releasing the bound ADP-ribose. Once ADP-ribosylated, the py dimer is inactive towards its effector enzymes, such as adenylyl cyclase, phosphoinositide 3-kinase and phospholipase C. It thus appears that endogenous P subunit mono-ADP-ribosylation might represent a novel cellular mechanism for the modulation of the G-protein-mediated signal transduction machinery through a direct regulation of the py dimer. In this study, the mechanisms that regulate endogenous mono-ADP-ribosylation of the p subunit have been investigated. The reaction appears to be under hormonal control both in vitro and in vivo, since the levels of ADP-ribosylated p are increased upon activation of certain G-protein-coupled receptors (GPCRs), such as thrombin, serotonin and cholecystokinin receptors. Conversely, hormonal stimulation by additional GPCRs, such as the GnRH receptor, can lead to a decrease in p subunit mono-ADP-ribosylation. Thus, ADP-ribosylation of the py dimer can be differentially regulated by different GPCRs in a receptor-type-dependent manner. In addition, the involvement of the ADP-ribosylating factor ARF6 in GnRH-mediated regulation of p subunit mono-ADP-ribosylation is demonstrated. Indeed, removal of ARF6 from plasma membranes results in loss of GnRH-mediated inhibition of p subunit mono-ADP-ribosylation, which can be fully restored by re-addition of purified ARF6. In conclusion, the results reported in this thesis allow the definition of the mechanisms that regulated endogenous ADP-ribosylation of the p subunit, and demonstrate a novel role for ARF6 in hormonal regulation of p subunit mono-ADP-ribosylation.

A joint probability density function (pdf) which uses the concept of a Lévy stable distribution is worked out. The theory is fitted to high-frequency US$/Japanese Yen exchange rate and low-frequency 19th century Irish stock data. The theory has been fitted both to price return and to waiting time data and the adherence to data, in terms of the chi-squared test statistic, has been improved when compared to the old theory.

I survey recent work on both pre-election coalition formation and post election coalition (or government) formation. A number of alternative rationales for the formation of parties are compared with the help of some illustrative examples.
Statistical Mechanical Approach to Lossy Data Compression:Theory and Practice

description: The encoder and decoder for lossy data compression of binary memoryless sources are developed on the basis of a specific-type nonmonotonic perceptron. Statistical mechanical analysis indicates that the potential ability of the perceptron-based code saturates the theoretically achievable limit in most cases although exactly performing the compression is computationally difficult. To resolve this difficulty, we provide a computationally tractable approximation algorithm using belief propagation (BP), which is a current standard algorithm of probabilistic inference. Introducing several approximations and heuristics, the BP-based algorithm exhibits performance that is close to the achievable limit in a practical time scale in optimal cases.

description: This paper studies the dominance-solvability (by iterated deletion of weakly dominated strategies) of general scoring rule voting games. The scoring rules we study include Plurality rule, Approval voting, Negative Plurality Rule, Borda rule and Relative Utilitarianism. We provide a classification of scoring rule voting games according to whether the sufficient conditions for dominance solvability require sufficient agreement on the best alternative or on the worst alternative. We also characterise the solutions when the sufficient conditions for dominance solvability are satisfied.

description: In this work we will study the polarizations of both leptons ($τ$) in the decay channel $B\to K^* τ^- τ^+$. In the case of the dileptonic inclusive decay $B\to K^* \ell^- \ell^+$, where apart from the polarization asymmetries of single lepton $\ell$, one can also observe the polarization asymmetries of both leptons simultaneously. If this sort of measurement is possible then we can have, apart from decay rate, FB asymmetry and the six single lepton polarization asymmetries (three each for $\ell^-$ and $\ell^+$), nine more double polarization asymmetries. This will give us a very useful tool in more strict testing of SM and the physics beyond. We discuss the double polarization asymmetries of $τ$ leptons in the decay mode $B\to K^* τ^- τ^+$ within the SM and the Minimal Supersymmetric extensions of it.

Non-Linear Canonical Transformations in Classical and Quantum Mechanics

subject: FOS: Physical sciences

description: $p$-Mechanics is a consistent physical theory which describes both classical and quantum mechanics simultaneously through the representation theory of the Heisenberg group. In this paper we describe how non-linear canonical transformations affect $p$-mechanical observables and states. Using this we show how canonical transformations change a quantum mechanical system. We seek an operator on the set of $p$-mechanical observables which corresponds to the classical canonical transformation. In order to do this we derive a set of integral equations which when solved will give us the coherent state expansion of this operator. The motivation for these integral equations comes from the work of Moshinsky and a variety of collaborators. We consider a number of examples and discuss the use of these equations for non-bijective transformations.

description: Purpose: The research compared the effect of electronic word-of-mouth advertising (e-WOM) and brand strength in consumers' decision to purchase an experience product and service. Theoretical framework: There is no clarity of the most significant influencer of the purchase decision: (1) being a strong brand induced by the company's efforts or (2) other consumers praise it, or (3) this praise intensifies the influence of brands previously strong. The research aimed at the possible generalization of these effects to experience product and service. Method: In two between-group experiments, consumers presented their strong or weak brand purchasing decisions with the positive, negative, or neutral presence of e-WOM for a product (smartphone) and a service (hosting reservation), both of experience. The authors used logistic regressions containing the purchase decision as the dependent variable. Findings: The results show the positive direct and moderating effects of e-WOM on the relationship between brand strength and purchase decision, with little difference between product and service. Positive e-WOM is more remarkable for the weak brand than for the strong brand (bracing effect). Negative e-WOM is greater for the strong brand than for the weak brand (weakening effect). Finally, negative e-WOM reduces the purchase decision probability for both brand strengths (aversive effect). Research implications: The study reveals patterns of e-WOM effects (bracing, weakening, aversive, and supplementary) on the influence of brand strength on purchase decisions. Originality: This paper brings the implications of e-WOM effects for brand management, revealing its patterns for better control.

description: We present timing and time-integrated spectral analysis of 127 bursts from SGR J1935+2154. These bursts were observed with the Gamma-ray Burst Monitor on the Fermi Gamma-ray Space Telescope and the Burst Alert Telescope on the Neil Gehrels Swift Observatory during the source's four active episodes from 2014 to 2016. This activation frequency makes SGR J1935+2154 the most burst prolific transient magnetar. We find the average duration of all the detected bursts to be much shorter than the typical, anticipated value. We fit the burst time-integrated spectra with two black-body functions, a Comptonized model and three other simpler models. Bursts from SGR J1935+2154 exhibit similar spectral properties to other magnetars, with the exception of the power law index from the Comptonized model, which correlates with burst fluence. We find that the durations and both black-body temperatures of the bursts have significantly evolved across the four active episodes. We also find that the burst time history exhibits two trends, which are strongly correlated with the decay of the persistent emission in each outburst.
description: A mistake has been corrected when calculating the burst isotropic energy from fluence. We updated the total burst energies in the rightmost column of Table 2 and the energy ratio between burst and persistent outburst for each episode in Section 4.2. All discussions and conclusions remain the same after these changes. An erratum has been accepted by ApJ. We are truly sorry for this mistake
WARFARE AND WELFARE? Understanding 19th and 20th Century Central Government Spending

description: This paper evaluates theories aiming to explain the size and growth of government spending, develops a framework inclusive of the so-called guns vs. butter tradeoff effect, and offers insights especially for the period 1870-1938. There were differences between the excessive and responsive government explanations, and between the long-run and short-run explanations, as well as cross-section and time series approaches. Here central government spending, conditioned by the regime characteristics, is proposed to be analyzed on the basis of the demand characteristics of military spending and social spending, their interaction, public debt constraints, as well as institutional constraints and other environmental variables.

description: The objective of this paper is to o¤er an answer to the question: why do some entrepreneurs wish to own another …rm in the future after having closed an unsuccessful one? We …rst show this question is relevant because making use of a sample of entrepreneurs in the UK who have experienced a business closure, we show that 45% of them have the desire to own another …rm in the future, despite having an unsuccessful experience in small …rm ownership. To tackle our question we develop a model where the pro…ts of the small …rm depend on two …rm-speci…c parameters: the e¢ciency parameter, which represents the skills of the entrepreneur to manage and cope e¢ciently with the everyday tasks of the small …rm, and the demand parameter, which denotes the success of the …rm’s product to attract demand or capture a market niche. It is found that our model answers our initial question by revealing the existence of a mechanism of entrepreneurial self-selection. Under such mechanism, skilful entrepreneurs are the only ones who wish to own another …rm in the future, regardless of the degree of success in their previous venture, whereas unskilful entrepreneurs prefer to go to wage work. We show this mechanism accounts not only for the empirical evidence relevant to our initial question, but also for the rest of cases of entrepreneurs’ attitudes after experiencing a business closure.

description: In order to enhance the performance of bismuth vanadium oxide (Bi4V2O11) we synthesized La doped Bi4V2O11 in different concentrations (La = 5%, 10%, 15%) by using sol-gel method. The nanoparticles are stabilized in tetragonal phase in the range of 50 nm particle size. With the help of XPS it was confirmed that in La/Bi4V2O11 lattice La is in 3+ oxidation state and replaces Bi3+ in the lattice. SEM and EDX show the amorphous nature and chemical compositions of the nanoparticles. The structural analysis and energy calculations revealed that La3+ ion replaces Bi3+ in Bi4V2O11 lattice without disturbing its host structure. The PL results revealed that photogenerated charges recombination was significantly reduced. The photocatalytic degradation of MB under visible light illumination is performed and the best photocatalytic activity among various compositions of La/Bi4V2O11 is shown by 15% La/Bi4V2O11 nanoparticles. 15% La/Bi4V2O11 photocatalyst show 98% of degradation of MB in 120 mins.

description: We experimentally demonstrate a prototype of a cylindrical enlarging lens capable of enhancing and restoring evanescent fields. The enabling phenomenon is the resonant excitation of coupled surface modes in a system of two cylindrical arrays of small resonant particles. As was shown in [J. Appl. Phys. 96, 1293 (2004)], this phenomenon in planar arrays can be used in electromagnetic near-field imaging. Here, we use a similar structure in a cylindrically symmetric configuration, which gives us a possibility to obtain an enlarged near-field image.
