Flavour independent search for Higgs bosons decaying into hadronic final states in e+e- collisions
Creators: name: The OPAL Collaboration

Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for the Higgsstrahlung process e+e- -> hZ is described, where the neutral Higgs boson h is assumed to decay into hadronic final states. In order to be sensitive to a broad range of models, the search is performed independent of the flavour content of the Higgs boson decay. The analysis is based on e+e- collision data collected by the OPAL detector at energies between 192 GeV and 209 GeV. The search does not reveal any significant excess over the Standard Model background prediction. Results are combined with previous searches at energies around 91 GeV and at 189 GeV. A limit is set on the product of the cross-section and the hadronic branching ration of the Higgs boson, as a function of the Higgs boson mass. Assuming the hZ coupling predicted by the Standard Model, and a Higgs boson decaying only into hadronic final states, a lower bound of 104 GeV/c2 is set on the mass at the 95% confidence level.

description: We use the complete Sydney-AAO Multi-object Integral field spectrograph (SAMI) Galaxy Survey to determine the contribution of slow rotators, as well as different types of fast rotators, to the stellar mass function of galaxies in the local Universe. We use stellar kinematics not only to discriminate between fast and slow rotators, but also to distinguish between dynamically cold systems (i.e., consistent with intrinsic axis ratios$<0.3$) and systems including a prominent dispersion-supported bulge. We show that fast rotators account for more than $80\%$ of the stellar mass budget of nearby galaxies, confirming that their number density overwhelms that of slow rotators at almost all masses from $10^{9}$ to $10^{11.5}{\rm M_\odot}$. Most importantly, dynamically cold disks contribute to at least $25\%$ of the stellar mass budget of the local Universe, significantly higher than what is estimated from visual morphology alone. For stellar masses up to $10^{10.5}{\rm M_\odot}$, this class makes up $>=30\%$ of the galaxy population in each stellar mass bin. The fact that many galaxies that are visually classified as having two-components have stellar spin consistent with dynamically cold disks suggests that the inner component is either rotationally-dominated (e.g., bar, pseudo-bulge) or has little effect on the global stellar kinematics of galaxies.

description: In this paper we study the trade creation effects of the EU preferential trade agreements (PTAs) in the agriculture and food sectors for a large sample of developing countries in the period 1990-2006. We build upon the existing literature on trade with heterogeneous firms, by investigating the extent to which the effect of PTAs occurs mainly through the extensive – number of exported products – or the intensive – volume of existing products – margins. A direct measure of the extensive margin based on a theoretically-founded decomposition of trade into the two margins is used. Empirically, we use a gravity framework in a panel data setting, and different estimators to deal with the issues of zero trade flows and of the presence of an upper bound in the dependent variable, which has recently been shown to raise new problems in the most common gravity econometric approaches. Main results show that the EU PTAs positively affect agricultural extensive margins, especially through other than tariff impacts linked with the PTA, while in the food industry the results are more sensitive to the estimator used. As far as the intensive margin is concerned, the PTA effect is only driven by the role of tariffs, while other effects of the PTAs do not exert any relevant impact on agricultural and food products.

description: Many developing countries attained high growth rates in different periods but income differences did not reduce significantly in these periods due to increase in income inequalities. Therefore, the key objective of this study was to analyze the relationship between income differences, trade and institutions in developing countries. This study has used panel data of the year 2000 to 2014 to explore the relationship between these variables. This study is based on sampling of two groups; 25 middle income countries and 24 low income countries. Pooled OLS, panel fixed effect and Driscoll and Kraay techniques were used in this study. The results showed the negative relations of imports, a significant role of political institutions and insignificant role of economic institutions in income distribution with GDP per capita among low income and middle-income countries. Moreover, the current study suggested that governments in developing countries should focus upon improving the performance of political and economic institutions in order to improve their prospects of getting investment opportunities.

description: The aim of this article is to assess of the impact of the European Union’s trade preferences on global trade, focusing on several methodological issues that are relevant to these preferences’ tradecreating impact. Using highly disaggregated 8-digit data in a theoretically grounded gravity model framework, we define an explicit measure of preferential tariff margins computed on alternative definitions based on a comparison between bilateral applied tariffs and two different reference levels: the Most Favoured Nation duty and a Constant Elasticity of Substitution price aggregator. From the methodological point of view, we show that the assessment of these policies’ impacts can be very sensitive to the definition of the preferential tariff margin. From a policy perspective, such preferential schemes have an actual impact on trade volumes, although with significant differences across sectors.
Size control of self-assembly polymeric nanospheres for biomedical applications
Creators: name: Reis Nogueira De Lima, Mariana
Publisher: name: No Publisher Supplied
Year: 2021

description: The control of nanospheres properties and the understanding of their influence on biological environments not only improve the drug delivery system outcome but also facilitates its clinical translation. Nanospheres size, for instance, has substantial impact on biological responses and have a direct effect on the particle performance after administration. This thesis presents a new method to tune the size of TyroSpheres and evaluates the copolymer structure-property relationship in the biomedical field. TyroSpheres are dynamic core-shell nanospheres constituted of a tyrosine-derived amphiphilic copolymer. The TyroSpheres hydrophobic core allows encapsulation of hydrophobic drugs at levels that surpass its aqueous solubility. On the other hand, its shell, composed of poly(ethylene glycol) (PEG) promotes particle stabilization. Even though the TyroSpheres were extensively studied with success for many different biomedical applications in the past, its size was never controlled. Here size control was achieved through precise synthesis and characterization of block copolymers (diblock (A-B) and triblock (A-B-A)) and of its respective tyrosine-derived monomeric units. In addition, the tyrosine-derived block copolymers were synthetically modified to optimize the copolymers performance as fusogenic agents for nerve repair.The work presented here promotes a deeper understanding of polymeric nanospheres, which could be expanded for other polymeric nano-delivery systems and also adds a novel property for the previously established TyroSpheres.

description: Over the years, Malaysia has progressively accelerated its economic development, thanks to the adherence to high rates of domestic savings and investment. Of which, the Employees Provident Fund (EPF) is one of the schemes that caters for the private sector workers. Specifically, this paper investigates the relationship between economic growth and EPF investment in Malaysia for the period of 1970 - 2014. The model, which is derived from the Cobb-Douglas production function, is tested by econometric techniques; Johansen cointegration and Granger causality within VECM. While the EPF investment is proven statistically insignificant in the short run, there is evidence of the saving/investment-led-growth hypothesis being the long run phenomenon for Malaysia. In view of the possible over-dependence on investment funds in general going forward, the policy makers are recommended to reinforce the government’s initiative in facilitating more business ventures as means to attract incoming funds, including FDI flows, towards streaming into the country.

description: We investigate and quantify various measures of bipartite and tripartite entanglement in the context of two and three flavor neutrino oscillations. The bipartite entanglement is analogous to the entanglement swapping resulting from a beam splitter in quantum optics. For the three neutrino systems various measures of tripartite entanglement are explored. The significant result is that a monogamy inequality in terms of negativity leads to a residual entanglement, implying true tripartite entanglement in the three neutrino system. This leads us to an analogy of the three neutrino state with a generalized class of W-state in quantum optics.

description: Simultaneous localization and mapping (SLAM) in highly dynamic environments is challenging due to the correlation complexity between moving objects and the camera pose. Many methods have been proposed to deal with this problem; however, the moving properties of dynamic objects with a moving camera remain unclear. Therefore, to improve SLAM's performance, minimizing disruptive events of moving objects with a physical understanding of 3D shapes and dynamics of objects is needed. In this paper, we propose a robust method, V3D-SLAM, to remove moving objects via two lightweight re-evaluation stages, including identifying potentially moving and static objects using a spatial-reasoned Hough voting mechanism and refining static objects by detecting dynamic noise caused by intra-object motions using Chamfer distances as similarity measurements. Our experiment on the TUM RGB-D benchmark on dynamic sequences with ground-truth camera trajectories showed that our methods outperform the most recent state-of-the-art SLAM methods.

We also discuss the related question of how the damping rates in the polarizability are related to energy-level decay rates.
ICT facilitating learning for all : investigating how interactive whiteboards can support teaching and learning for diverse learners in an elementary, language arts classroom

description: Changing information and communication technologies (ICT) are radically altering how people navigate their world. Our students are adept at sending emails, texting friends and surfing the World Wide Web, but only within the last five to ten years have schools begun to improve the ICT available to them. As new ICT are incorporated into schools, it is important for educators to understand how to utilize their capabilities. Recently, Vancouver schools have begun to purchase interactive whiteboards (IWB). Initial observations from teachers reveal that it seems like student engagement is increasing with IWB use. Perhaps more important is the question is teaching and learning shifting in response to IWB capabilities? Current research discusses the IWBs multimodal potential, including visual, auditory and tactile, that support student's learning. In addition, the research shows that teachers need a certain level of technological competency in order to fully incorporate these learning modalities and maximize the interactivity. This interactive nature has the potential to support our students' meaning making process in language arts by supporting critical literacy strategies, multi-literacies and reader response theory. Teachers who are knowledgeable about these possibilities will be able to more fully resource their students and support their learning. As an example, a design for IWB unit plans is included to assist other teachers who wish to incorporate the learning modalities and interactive nature of the IWB into their classrooms.

description: A proper understanding of the links between varying gene expression levels and complex trait adaptation is still lacking, despite recent advances in sequencing techniques leading to new insights on their importance in some evolutionary processes. This calls for extensions of the continuum-of-alleles framework first introduced by Kimura (1965) that bypass the classical Gaussian approximation. Here, we propose a novel mathematical framework to study the evolutionary dynamics of quantitative alleles for sexually reproducing populations under natural selection and competition through an integro-differential equation. It involves a new reproduction operator which allows to use techniques based on the maximum principle, unlike the infinitesimal model operator used in other studies with sexual reproduction. In an asymptotic regime where initially the population has a small phenotypic variance, we analyse the long-term dynamics of the phenotypic distributions according to the methodology of small variance (Diekmann et al. 2005). Under some assumptions on the limit equation, we show that the population remains monomorphic, that is the phenotypic distribution remains concentrated as a moving Dirac mass. Moreover, in the case of a monomorphic distribution we derive a canonical equation describing the dynamics of the dominant alleles.

description: Dados da Organização Mundial de Saúde (OMS) indicam que a qualidade do ar nos centros urbanos vem piorando de forma alarmante nos últimos anos. O problema é agravado em países onde a matriz energética é baseada na queima em larga escala de combustíveis fósseis e/ou biomassa vegetal. Um parâmetro para indicar a piora na qualidade do ar é a concentração de material particulado PM2.5 na atmosfera (poeira inalável com diâmetro menor que 2,5 micrometros). Na Amazônia, essas partículas são lançadas na atmosfera principalmente no período seco, quando ocorre a queima da biomassa de resíduos florestais do desmatamento, e de grandes áreas de vegetação aberta (savanas naturais e pastagens artificiais). A inalação desse material poluente pode causar sérios problemas de saúde devido a danos nos pulmões e circulação sanguínea.

description: We study future DUNE sensitivity to various electromagnetic couplings of neutrinos, including magnetic moments, milli-charges, and charge radii. The DUNE PRISM capabilities play a crucial role in constraining the electron flavored couplings. We find that DUNE will be able to place the strongest terrestrial constraint on the muon-neutrino magnetic moment by improving on LSND's bounds by roughly a factor of two, although Borexino's solar constraint will still be stronger. For the muon neutrino milli-charge DUNE can place the leading experimental bound, with two orders of magnitude improvement compared to the existing COHERENT constraint. Finally, DUNE may be able to test the SM prediction for the muon neutrino charge radius, by placing a constraint two times better than CHARM-II and CCFR experiments.

description: We continue the study of the renormalization group and decoupling of massive fields in curved space, started in the previous article and analyse the higher derivative sector of the vacuum metric-dependent action of the Standard Model. The QCD sector at low-energies is described in terms of the composite effective fields. For fermions and scalars the massless limit shows perfect correspondence with the conformal anomaly, but similar limit in a massive vector case requires an extra compensating scalar. In all three cases the decoupling goes smoothly and monotonic. A particularly interesting case is the renormalization group flow in the theory with broken supersymmetry, where the sign of one of the beta-functions changes on the way from the UV to IR.

description: We present a Bayesian inference on the neutral hydrogen fraction of the intergalactic medium (IGM), $x_{\textrm{HI}}$, at $z \sim$ 6-8 using the properties of Lyman break galaxies during the Epoch of Reionization. We use large samples of LBG candidates at $5.5 \leq z \leq 8.2$ with spectroscopy from Keck/DEIMOS and Keck/MOSFIRE. For each galaxy, we incorporate either the Lyman-$α$ equivalent width (EW) for detections or the EW limit spectrum for nondetections to parameterize the EW distribution at various ultraviolet brightnesses for a given redshift. Using our reference sample of galaxy candidates from the ionized universe at $z$ $\sim$ 6.0, we are able to infer $x_{\textrm{HI}}$ at two redshifts: $z$ $\sim$ 6.7 and $z$ $\sim$ 7.6. This work includes intrinsically faint, gravitationally lensed galaxies at $z$ $\sim$ 6.0 in order to constrain the intrinsic faint-end Ly$α$ EW distribution and provide a comparable population of galaxies to counterparts in our sample that are at higher redshift. The inclusion of faint galaxy candidates, in addition to a more sophisticated modelling framework, allows us to better isolate effects of the interstellar medium and circumgalactic medium on the observed Lyman-$α$ distribution from those of the IGM. We infer an upper limit of $x_{\textrm{HI}}$ $\leq$ 0.25 at $z$ = 6.7 $\pm$ 0.2 and a neutral fraction of $x_{\textrm{HI}}$ = $0.83^{+0.08}_{-0.11}$ at $z$ = 7.6$\pm$ 0.6, both within 1$σ$ uncertainty, results which favor a moderately late and rapid reionization.

description: Isoflavones are phytoestrogens found in plant-based foods and nutritional supplements. Experimental studies show a positive association between isoflavones and hypothyroidism, but epidemiological findings are conflicting. We used multivariable linear regression to examine the association between urinary isoflavone concentrations and serum thyroid hormone concentrations in the National Health and Nutrition Examination Survey (2007–2010). In this study, we found that Daidzein and O-DMA associations with free T4 were stronger among women: a 10-fold increase in daidzein was associated with a 3.2% (95% CI: 1.9%, 4.5%) increase in women and a 0.6% (95% CI: −1.7%, 0.6%) decrease in men and a 10-fold increase in O-DMA was related to a 2.0% (95% CI: 1.1%, 2.9%) increase in women and a 0.3% (95% CI: −1.2%, 0.5%) decrease in men. In this study, selected urinary isoflavone concentrations were associated with serum thyroid hormone concentration in a sex-dependent fashion.

description: The aim of this paper is to assess the causal impact of trade policy distortions on food security. The added value of this work is twofold: i) its use of a non-parametric matching technique with continuous treatment, namely the Generalised Propensity Score (GPS) to address the self selection bias; ii) its analysis of heterogeneity in treatment (by commodities) as well as in outcome (i.e. dierent dimensions of food security). The results of our estimates clearly show that trade policy distortions are, overall, signicantly correlated with the various dimensions of food security analysed. Both discrimination against agriculture and 'excessive' support lead to poor performances in all dimensions of food security (availability, access, utilisation and stability).

description: This study assessed the subjective well-being (SWB), or welfare, of the elderly in retirement homes in Bangkok, and examined related factors, particularly from the perspective of happiness economics, since the empirical evidence in this aspect is still limited. Primary data was collected by distributing questionnaires and carrying out in-depth interviews between August 2017 and November 2017. In total, 120 participants were included, of which 60 persons were from public retirement homes (44 women and 16 men) and 60 persons from private retirement homes (40 women and 20 men). The cross-sectional data were analyzed using standard descriptive statistics and estimations of logit regressions. The logit regression results reveal that the following were positively related with SWB/welfare in all regressions as hypothesized: a short distance between the retirement home and a temple/hospital, a retirement home located in the participant’s hometown, and interest in obtaining free college courses. Meanwhile, the coefficients on the need for a higher number of care staff were negative. Among the control variables, being female, being older, completing secondary school, and having plenty of money to spend were strongly and positively associated with SWB/welfare. It was noteworthy that receiving a total Barthel ADL index scores of more than 10 and having family and friends visit regularly (once or a few times a week) played an important role in increasing participants’ SWB/welfare in both public and private retirement homes.

As a first step to study string interactions, we compute the interaction of two decaying D0-branes in terms of free fermions. This computation is compared with the string theory cylinder diagram using the rolling tachyon ZZ boundary states.

description: Control of quantum coherence in many-body system is one of the key issues in modern condensed matter. Conventional wisdom is that lattice vibration is an innate source of decoherence, and amounts of research have been conducted to eliminate lattice effects. Challenging this wisdom, here we show that lattice vibration may not be a decoherence source but an impetus of a novel coherent quantum many-body state. We demonstrate the possibility by studying the transverse-field Ising model on a chain with renormalization group and density-matrix renormalization group method, and theoretically discover a stable $\mathcal{N}=1$ supersymmetric quantum criticality with central charge $c=3/2$. Thus, we propose an Ising spin chain with strong spin-lattice coupling as a candidate to observe supersymmetry. Generic precursor conditions of novel quantum criticality are obtained by generalizing the Larkin-Pikin criterion of thermal transitions. Our work provides a new perspective that lattice vibration may be a knob for exotic quantum many-body states.

description: It is argued that $4d$ $SU(N)$ $\mathcal{N}=4$ SYM has an accumulation line of zero-temperature topologically ordered phases. Each of these phases corresponds to $N$ bound states charged under electromagnetic $\mathbb{Z}^{(1)}_N$ one-form symmetries. Each of the $N$ bound states is made of two Dyonic flux components each of them extended over a two dimensional surface. They are localized at the fixed loci of a rotational action, and are argued to correspond to conformal blocks (or primaries) of an $SU(N)_1$ WZNW model on a two-torus.

description: Space weather events may cause damage to several fields, including aviation, satellites, oil and gas industries, and electrical systems, leading to economic and commercial losses. Solar flares are one of the most significant events, and refer to sudden radiation releases that can affect the Earth's atmosphere within a few hours or minutes. Therefore, it is worth designing high-performance systems for forecasting such events. Although in the literature there are many approaches for flare forecasting, there is still a lack of consensus concerning the techniques used for designing these systems. Seeking to establish some standardization while designing flare predictors, in this study we propose a novel methodology for designing such predictors, further validated with extreme gradient boosting tree classifiers and time series. This methodology relies on the following well-defined machine learning based pipeline: (i) univariate feature selection; (ii) randomized hyper-parameter optimization; (iii) imbalanced data treatment; (iv) adjustment of cut-off point of classifiers; and (v) evaluation under operational settings. To verify our methodology effectiveness, we designed and evaluated three proof-of-concept models for forecasting $\geq C$ class flares up to 72 hours ahead. Compared to baseline models, those models were able to significantly increase their scores of true skill statistics (TSS) under operational forecasting scenarios by 0.37 (predicting flares in the next 24 hours), 0.13 (predicting flares within 24-48 hours), and 0.36 (predicting flares within 48-72 hours). Besides increasing TSS, the methodology also led to significant increases in the area under the ROC curve, corroborating that we improved the positive and negative recalls of classifiers while decreasing the number of false alarms.

Does Food Aid Disrupt Local Food Market? Evidence from Rural Ethiopia

description: This paper analyses empirically the impact of food aid on wheat production, sales and purchases in rural Ethiopia between 1994 and 2009. We distinguish between the impact at the intensive margin (on quantities) and at the extensive margin (on the very decision to produce or go to the market to buy or sell). The panel dimension allows us to deal with food aid selection. We find that the impact of food aid goes through the extensive margin while pure quantity effects, once controlled for market participation and production choice, are not significant. Food aid reduces the probability of being a producer albeit the size of the effect is small. It also increases the probability of being a seller and decreases the probability of being a buyer after 2004, the year when the rules of food aid allocation changed in Ethiopia. Other factors such as storage capacity, distance to the nearest market, and the frequency the market is held also matter in the decision to sell or buy.
Impact of Polarized Galactic Foreground Emission on CMB Lensing Reconstruction and Delensing of B-Modes

description: Next generation CMB experiments such as CMB-S4 aim at measuring the CMB lensing potential at sub-percent precision where most of the constraining power will come from CMB polarization. We investigate the prospects of achieving this goal in the presence of large-scale, diffuse galactic foreground emission by using non-Gaussian sky simulations and exploit multi-frequency information to clean those. We show that, while prior to foreground cleaning, cosmological parameter estimates from the contaminated lensing potential estimation can be significantly biased, these can be successfully mitigated by applying a parametric foreground cleaning approach. We further observe no significant additional bias in the delensed B-mode power spectrum after applying foreground cleaning and are therefore able to obtain an unbiased measurement of the tensor-to-scalar ratio, $r$, after delensing.

description: This paper analyzes whether or not different non-tariff measures (NTM) like a standard or a mandatory label can be considered as protectionist in presence of market imperfections. From a welfare-based approach, protectionism occurs when the instrument maximizing domestic welfare is different from the alternative instrument maximizing international welfare inclusive of foreign profits. A framework taking into account different tools shows the complexity for characterizing protectionism related to different NTM. When the standard impacts variable costs, the mandatory label can be protectionist. When the standard impacts sunk costs, the standard can be protectionist. The framework is also useful for empirically characterizing the impact of NTM related to a specific product. An application to shrimp trade illustrates the feasibility of the welfare measure, for an ex ante evaluation of possible environmental regulations that could be implemented in the future. This application confirms that the tool maximizing domestic welfare does not systematically correspond to the tool maximizing international welfare.

description: We analyse the effectiveness of catastrophe bonds for the financial management of catastrophic risk in the transport and infrastructure industries. We illustrate how these financial instruments are becoming a valuable tool for non-financial firms in the risk management of catastrophic events, supplementing the traditional insurance/reinsurance channel, especially during times of constraints in the insurance industry. We also review cat bond issues sponsored by infrastructure and transport companies, highlighting the usefulness of these structured financial instruments in the management of the catastrophe exposure in these industries. Policy indications are finally given.
