One loop corrections to quantum hadrodynamics with vector mesons

Publisher: name: arXiv

Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: The renormalized elastic $ππ$ scattering amplitude to one loop is calculated in the chiral limit in the $σ$ model and in a Quantum Hadrodynamic model (QHD-III) with vector mesons. It is argued that QHD-III reduces to the linear $σ$ model in the limit that the vector meson masses become large. The pion decay constant is also calculated to 1-loop in the $σ$ model, and at tree level in QHD-III; it is shown that the coefficient of the tree level term in the scattering amplitude equals $F_π^{-2}$. The 1-loop correction of $F_π$ in QHD-III violates strong isospin current conservation. Thus,it is concluded that QHD-III can, at best, only describe the strongly interacting nuclear sector.

description: What Blue Springs County Park lacks in size, it makes up for in cultural resources, both in terms of density and variety. For example, three archaeological sites were recorded within the park at the time of state acquisition. While the CARL Archaeological Survey intended to do a typical reconnaissance survey there, we ended up doing mostly gratis mitigation work to help Jackson County save money. Consequently, much work still needs to be done to get a better and clearer understanding of the park's historical resources. One thing we did not accomplish was to compare sites in the park with specific soil types and natural communities. The reason we could not meet this goal is that data on soils and original natural comminutes have yet to be digitized. We already know, nonetheless, that the entire tract is rich with significant sites. All test pits placed on the property thus far have produced historical resources of some sort. Unfortunately, some previous land uses of the property, particularly some of the contouring that occurred closest to the spring, have altered the area's archaeological integrity, although much of the tract bears only minor scarring.

description: Over the past decade, in West African cocoa production, efforts to deliver training on more sustainable production techniques or on more business-oriented farm management have been undertaken by various public and private actors. Yet, the success of these interventions seems to be limited, especially given the continuous low incomes of cocoa farmers, high rates of deforestation and many other persisting challenges in the cocoa sector. 
Focusing on the variances between different household types in their perceptions regarding most pressing challenges, difficulties with the application of training contents, and needs for change, this study seeks to contribute to an improved understanding of impact factors for successful sustainability interventions and the achievement of a Living Income. The main research questions are as follows: How do household characteristics impact cocoa farmers' livelihoods and production challenges, including the ability to adapt training contents? Where do the different household types see most need for change regarding sustainability interventions and in their local enabling environment? 
In the frame of accompanying research, the study investigates perceptions of cocoa farmers in five cocoa areas in Côte d'Ivoire (Aboisso, Agboville, Abengourou, Divo and Yamoussoukro) targeted by the PRO-PLANTEURS project of GIZ. Most of these cocoa farmers have received training in Farmer Business Schools and other sensitization measures, such as on agroforestry and on-farm diversification in the past years. To assess household differences and related impacts, a household survey among approximately 300 targeted cocoa farmers was realized in order to quantify farmers' perceptions towards implementation of project activities and livelihood challenges. Additionally, focus group discussions with representatives of targeted cooperatives were held as well as a participatory multi-stakeholder workshop on implementation challenges and experiences was conducted. Applying Principal Component Analysis and Hierarchical Cluster Analysis based on Principal Components, four farm types have been identified for further analyses to identify farmers' particularities regarding needs and ability to apply training contents and sustainable production techniques. 
The overall objective of this accompanying research is to identify best fit strategies and enabling environments for the achievement of cocoa farmers' Living Income. By answering the presented research questions, the study seeks to provide the basis for an enhanced understanding and evaluation of strategies' success factors and opportunities for improvements of sustainability interventions.

description: Attachment Theory is one of the most frequently used frameworks which revolutionised
the understanding of human behaviour, from early childhood to adulthood. Attachment
Theory’s scholarly output was examined using a quantitative bibliometric approach, based
on rigorous facts extracted from the WoS databases from 1970 to 2017. Overall, 1,700
documents in the category “Psychology” with the topic “Attachment Theory” were analysed
to fnd trends of publications, networking coupling, keywords frequencies, top authors, and
highly cited papers. A qualitative content analysis of the top 20 documents with the highest
average citation per year was done to provide insight on document approaches. The results
show that the scientifc productivity in “attachment theory” is highly skewed. The authors
recommend publishing attachment theory related articles in an open access journal. There is
a need for further interdisciplinary research and practice collaboration to move beyond the
sole psychological approach and realise the importance of multi-disciplinary approaches.

Cardiovascular autonomic responses in pre- and post-ganglionic models of chronic autonomic failure
Creators: name: Young, Tim
Publisher: name: Imperial College London
Year: 2008

description: Multiple System Atrophy (MSA) and Pure Autonomic Failure (PAF) are contrasting models of Chronic Autonomic failure. PAF primarily involves the post-ganglionic autonomic nervous system, whilst in MSA the pre-ganglionic structures are impaired. My central hypothesis is that this underlying neuropathological difference between MSA and PAF will lead to differing cardiovascular responses. I will assess the cardiovascular effects of known pressor and vasomotor stimuli (mental arithmetic, cold pressor test, isometric exercise, water ingestion, inhaled CO2 and inspiratory gasp) in MSA and PAF. Neurohormonal aspects will be explored by comparing the cardiovascular effects of the α2-adrenoceptor agonist clonidine with serum noradrenaline levels in these groups, as well as comparing supine antidiuretic hormone (ADH) levels after head up tilt and correlating these with supine blood pressure (BP). As well as contrasting the cardiovascular responses, I will use the water ingestion studies to examine effects on orthostatic hypotension, a common complication of both MSA and PAF. To measure cardiovascular responses during these studies I have used the Portapres II device to obtain continuous, non-invasive, beat-to-beat measurements of BP and heart rate (HR). Subsequent Model flow analysis using Beatscope software has then been used to calculate further cardiovascular indices, including cardiac output (CO), stroke volume (SV) and total peripheral resistance (TPR). In addition, intermittent BP and HR measurements have been obtained with an automated sphygmomanometer (Dinamap). Finally, peripheral vasomotor responses have been recorded by means of the Laser Doppler perfusion meter.
On the sensitivity of magnetic cycles in global simulations of solar-like stars

description: The periods of magnetic activity cycles in the Sun and solar-type stars do not exhibit a simple or even single trend with respect to rotation rate or luminosity. Dynamo models can be used to interpret this diversity, and can ultimately help us understand why some solar-like stars do not exhibit a magnetic cycle, whereas some do, and for the latter what physical mechanisms set their magnetic cycle period. Three-dimensional non-linear magnetohydrodynamical simulations present the advantage of having only a small number of tunable parameters, and produce in a dynamically self-consistent manner the flows and the dynamo magnetic fields pervading stellar interiors. We conducted a series of such simulations within the EULAG-MHD framework, varying the rotation rate and luminosity of the modeled solar-like convective envelopes. We find decadal magnetic cycles when the Rossby number near the base of the convection zone is moderate (typically between 0.25 and 1). Secondary, shorter cycles located at the top of the convective envelope close to the equator are also observed in our numerical experiments, when the local Rossby number is lower than 1. The deep-seated dynamo sustained in these numerical experiments is fundamentally non-linear, in that it is the feedback of the large-scale magnetic field on the large-scale differential rotation that sets the magnetic cycle period. The cycle period is found to decrease with the Rossby number, which offers an alternative theoretical explanation to the variety of activity cycles observed in solar-like stars.

Muscular dystrophy cell therapy - an in utero approach using human fetal mesenchymal stem cells
Creators: name: Wu, Pensee
Publisher: name: Imperial College London
Year: 2009

description: Duchenne muscular dystrophy (DMD) is the most prevalent genetic neuromuscular disorder and affects 1 in 3,500 live male births. Lack of the protein dystrophin in muscle fibres causes permanent muscle damage, is lethal and despite various potential therapeutic strategies aimed at restoring dystophin expression, has no cure. As DMD affects all skeletal muscles as well as the heart, a systemic treatment would be necessary and in utero stem cell transplantation is a promising way of achieving this. The identification of human fetal mesenchymal stem cells (hfMSC) in early gestation fetal blood offers the prospect of allogeneic or autologous cell therapy, while intrauterine administration would capitalise on ontological opportunities unique to the developing fetus. The aim of the study was to improve hfMSC engraftment and contribution to skeletal muscle fibres following intrauterine transplantation (IUT) in a mouse model of DMD. My project demonstrated that hfMSCs are easily isolated and expandable with the ability to undergo myogenesis in vitro. HfMSCs differentiated into mature myotubes following exposure to galectin-1 conditioned medium, while galectin-1 transduced hfMSCs showed significantly higher expression of myogenic markers compared to non-transduced hfMSCs. Co-culture experiments provided an in vitro model to explore the underlying mechanism for muscle differentiation of hfMSCs following IUT. HfMSCs were able to form chimeric myotubes by fusing with myoblasts isolated from E15 mouse embryos, evidence that they should be able to fuse with developing muscle fibres in vivo. Engraftment and differentiation into muscle fibres of hfMSCs injected intra-peritoneally into E15 mouse embryos in vivo was enhanced by using immunodeficient dystrophic host mice, postnatal muscle injury and additional neonatal hfMSC transplantation following IUT. In conclusion, my thesis supports the use of hfMSC as an attractive source for cell therapy and provides the background for further studies to optimise their engraftment and differentiation to underpin future clinical applications.

description: In 1971, the Division of Archives, History and Records Management (now the Division of Historical Resources) at the request of the Florida Department of Transportation conducted archaeological excavations at site 8MD18 just southwest of Madison, Florida. The Hutto Pond site was discovered during a survey of the proposed 1-10 corridor (Interstate 10 ultimately would serve as a direct link across the southern U.S. between Jacksonville and Los Angeles) by state archaeologist B. Calvin Jones. It was deemed potentially significant, which triggered Phase II test excavations at Hutto Pond. Unfortunately, back then DOT would not fund the analyses and write-ups of excavated archaeological sites. More than 44 years after the fieldwork occurred there, though, an opportunity arose to complete the analysis of artifacts by Louis Tesar and to craft a report on this highly significant but long-neglected archaeological site.

description: We analyze the reaction dynamics of central Pb+Pb collisions at 160 GeV/nucleon. First we estimate the energy density pile-up at mid-rapidity and calculate its excitation function: The energy density is decomposed into hadronic and partonic contributions. A detailed analysis of the collision dynamics in the framework of a microscopic transport model shows the importance of partonic degrees of freedom and rescattering of leading (di)quarks in the early phase of the reaction for E > 30 GeV/nucleon. The energy density reaches up to 4 GeV/fm^3, 95% of which are contained in partonic degrees of freedom. It is shown that cells of hadronic matter, after the early reaction phase, can be viewed as nearly chemically equilibrated. This matter never exceeds energy densities of 0.4 GeV/fm^3, i.e. a density above which the notion of separated hadrons loses its meaning. The final reaction stage is analyzed in terms of hadron ratios, freeze-out distributions and a source analysis for final state pions.

description: Among confirmed central compact objects (CCOs), only three sources have measured period and period derivatives. We have investigated possible evolutionary paths of these three CCOs in the fallback disc model. The model can account for the individual X-ray luminosities and rotational properties of the sources consistently with their estimated supernova ages. For these sources, reasonable model curves can be obtained with dipole field strengths $\sim$ a few $\times 10^9$ G on the surface of the star. The model curves indicate that these CCOs were in the spin-up state in the early phase of evolution. The spin-down starts, while accretion is going on, at a time $t \sim 10^3 - 10^4$ yr depending on the current accretion rate, period and the magnetic dipole moment of the star. This implies that some of the CCOs with relatively long periods, weak dipole fields and high X-ray luminosities could be strong candidates to show spin-up behavior if they indeed evolve with fallback discs.

description: We finalize the study of collapsing D-branes in one-parameter models by completing the analysis of the associated hypergeometric hierarchy. This brings further evidence that the phenomenon of collapsing 6-branes at the mirror of the `conifold' point in IIA compactifications on one-parameter Calabi-Yau manifolds is generic. It also completes the reduction of the study of higher periods in one-parameter models to a few families which display characteristic behaviour. One of the models we consider displays an exotic form of small-large radius duality, which is a consequence of an ``accidental'' discrete symmetry of its moduli space. We discuss the implementation of this symmetry at the level of the associated type II string compactification and its action on D-brane states. We also argue that this model admits two special Lagrangian fibrations and that the symmetry can be understood as their exchange.

Steam cycle options for capture-ready power plants, retrofits and flexible operation with post-combustion CO2 capture
Creators: name: Lucquiaud, Mathieu
Publisher: name: Imperial College London
Year: 2010

description: The energy penalty for post‐combustion carbon dioxide capture from fossil‐fired power plants can be greatly reduced ‐ independently of the intrinsic heat of regeneration of the solvent used ‐ by effective thermodynamic integration with the power cycle. Yet expected changes in electricity generation mix and the current immaturity of post‐combustion capture technology are likely to make effective thermodynamic integration throughout the operating life of such plants a challenging objective to achieve because of a requirement for extensive part‐load operation and also for matching to future technology improvements. Most previous published studies have, however, focused on base‐load operation of the power cycle and the carbon dioxide capture plant and with the assumption of a fixed technology. For carbon dioxide capture‐ready plants the characteristics of the capture plant are also not known when the plant is designed. The plant must operate initially without capture at a similar efficiency to ‘standard’ plants to be competitive. Capture‐ready plants then also need to be able to be retrofitted with unknown improved solvents and to be capable of integration with a range of future solvents. This study shows that future upgradability for post‐combustion capture systems can be facilitated by appropriate steam turbine and steam cycle designs. In addition fossil‐fired power plants with postcombustion capture may need to be able to operate throughout their load range with the capture unit by‐passed, or with intermediate solvent storage to avoid the additional emissions occurring when the absorption column is by‐passed. Steam cycles with flexible steam turbines can be adequately designed to accommodate for part‐load operation with these novel operating conditions and with rapid ramp rates. Several approaches for effective capture‐ready pulverised coal and natural gas plants are also described. These achieve identical performance before retrofit to a conventional plant with the same steam conditions, but have the potential to perform well after capture retrofit with a wide range of solvents, at the expense of only a small efficiency penalty compared to hypothetical plants built with perfect foreknowledge of the solvent energy requirements. For existing plants that were not made capture‐ready, and provided sufficient space is available and other physical limits are not too constraining, ways to achieve effective thermodynamic integration are also discussed.

description: In central collisions at relativistic heavy ion colliders like the Relativistic Heavy Ion Collider RHIC/Brookhaven and the Large Hadron Collider LHC (in its heavy ion mode) at CERN/Geneva, one aims at detecting a new form of hadronic matter --- the Quark Gluon Plasma. We discuss here a complementary aspect of these collisions, the very peripheral ones. Due to coherence, there are strong electromagnetic fields of short duration in such collisions. They give rise to photon-photon and photon-nucleus collisions with high flux up to an invariant mass region hitherto unexplored experimentally. After a general survey photon-photon luminosities in relativistic heavy ion collisions are discussed. Then photon-photon physics at various gamma-gamma-invariant mass scales is discussed. The region of several GeV, relevant for RHIC is dominated by QCD phenomena (meson and vector meson pair production). Invariant masses of up to about 100 GeV can be reached at LHC, and the potential for new physics is discussed. Lepton-pair production, especially electron-positron pair production is copious. Due to the strong fields there will be new phenomena, especially multiple e+e- pair production.

description: We present evidence for new, non-trivial RG fixed points with dual magnetic descriptions in $N=1$ supersymmetric $SP(N_c)$ and $SO(N_c)$ gauge theories. The $SP(N_c)$ case involves matter $X$ in the antisymmetric tensor representation and $N_f$ flavors of quarks $Q$ in the fundamental representation. The $SO(N_c)$ case involves matter $X$ in the symmetric tensor representation and $N_f$ flavors of quarks $Q$ in the vector representation of $SO(N_c)$. Perturbing these theories by superpotentials $W(X)$, we find a variety of interesting RG fixed points with dual descriptions. The duality in these theories is similar to that found by Kutasov and by Kutasov and Schwimmer in $SU(N_c)$ with adjoint $X$ and $N_f$ quarks in the fundamental.

The latter class includes plane-wave type backgrounds (admitting a covariantly constant null Killing vector) and backgrounds with two null Killing vectors (e.g., fundamental string solution). $D>4$ chiral null models describe some exact $D=4$ solutions with electromagnetic fields, for example, extreme electric black holes, charged fundamental strings and their generalisations. In addition, there exists a class of conformal models representing axially symmetric stationary magnetic flux tube backgrounds (including, in particular, the dilatonic Melvin solution). In contrast to spherically symmetric chiral null models for which the corresponding conformal field theory is not known explicitly, the magnetic flux tube models (together with some non-semisimple WZW models) are among the first examples of solvable unitary conformal string models with non-trivial $D=4$ curved space-time interpretation. For these models one is able to express the quantum hamiltonian in terms of free fields and to find explicitly the physical spectrum and string partition function.

Linear perturbations of an anisotropic Bianchi I model with a uniform magnetic field
Creators: name: Di Gioia, Federico

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this work, we study the effect of a magnetic field on the growth of cosmological perturbations. We develop a mathematical consistent treatment in which a perfect fluid and a uniform magnetic field evolve together in a Bianchi I universe. We then study the energy density perturbations on this background with particular emphasis on the effect of the background magnetic field. We develop a full relativistic solution which refines previous analysis in the relativistic limit, recovers the known ones in the Newtonian treatment with adiabatic sound speed, and it adds anisotropic effects to the relativistic ones for perturbations with wavelength within the Hubble horizon. This represents a refined approach on the perturbation theory of an isotropic universe in GR, since most of the present studies deal with fully isotropic systems.

Subjects: subject: 160699 Political Science not elsewhere classified
subject: FOS: Political science

description: Voter turnout is an important factor when attempting to assess a population’s preferences accurately. Understanding the factors that influence voter turnout will aid in raising electoral participation. This paper focuses on the effect of informed voters and voter confidence on voter turnout. It is concluded that informed voters are strongly linked with higher voter turnouts. Voter confidence is decomposed into voter confidence (perception of electoral integrity) and voter self-confidence (perception of the “correct” decision being made). It is concluded that increased voter confidence is linked to higher voter turnout. It is foreshadowed based on research outside the political domain that voter self-confidence would show similar results if tested.

description: When tuning software configuration for better performance (e.g., latency or throughput), an important issue that many optimizers face is the presence of local optimum traps, compounded by a highly rugged configuration landscape and expensive measurements. To mitigate these issues, a recent effort has shifted to focus on the level of optimization model (called meta multi-objectivization or MMO) instead of designing better optimizers as in traditional methods. This is done by using an auxiliary performance objective, together with the target performance objective, to help the search jump out of local optima. While effective, MMO needs a fixed weight to balance the two objectives-a parameter that has been found to be crucial as there is a large deviation of the performance between the best and the other settings. However, given the variety of configurable software systems, the "sweet spot" of the weight can vary dramatically in different cases and it is not possible to find the right setting without time-consuming trial and error. In this paper, we seek to overcome this significant shortcoming of MMO by proposing a weight adaptation method, dubbed AdMMO. Our key idea is to adaptively adjust the weight at the right time during tuning, such that a good proportion of the nondominated configurations can be maintained. Moreover, we design a partial duplicate retention mechanism to handle the issue of too many duplicate configurations without losing the rich information provided by the "good" duplicates.
 Experiments on several real-world systems, objectives, and budgets show that, for 71% of the cases, AdMMO is considerably superior to MMO and a wide range of state-of-the-art optimizers while achieving generally better efficiency with the best speedup between 2.2x and 20x.

description: Pollen viability is defined as a mechanism of male fertility, necessary for the reproduction of plants, since its mission is the fertilization of the ovules for the formation of seeds. Knowing this process is key to improving quality techniques and grain germination capacity, which are related to flower biology, used to refer to germination and viability, which directly or indirectly influence the fertilization process in plants. flowers. The development of the cocoa flower is subject to genetic, environmental, pathological, nutritional factors, the alteration between these factors affects fertilization and production in cocoa plantations. The heterogeneity in the crops, can present low yields, among them it can be associated with the reproductive development of the crop, size of the fruits, number of seeds, which could be associated with pollen viability, being these an important tool in the programs of genetic improvement.
Sexual compatibility increases the possibility of successful fertilization and is a key aspect for increasing productivity. Sexual incompatibility considerably limits the productivity of trees, since it cannot fertilize itself or with different material, making partial or total fertilization difficult due to inhibition due to chemical and physiological causes or lack of stimulating substances for the growth of the pollen tube.. The present study was carried out by the National Federation of Cocoa Growers with resources from the National Cocoa Fund, through the research program, where the objective was to evaluate the qualitative and quantitative differentiation of viable pollen grains to calculate the percentage of germination in 36 materials of cocoa, through in vitro tests in culture media, each one evaluated with five flowers, with counts in 250 pollen grains taken at random per flower, 50 per anther, for a total of 1,250 grains, the germination percentage is carried out two hours after sowing.
It was possible to make a classification of the evaluated materials according the in-vitro germination capacity into four groups: high (above 75%): FSA12, FLE3, FSV1, FTA2, FSA20, FCHI8, FGI4; intermediate-high (50-75 %): FTA4, FEAR26, FSV41, FSV30, CCN51, ICS1, FLE4, FBO1; intermediate-low (25-50%): ICS39, EET8, ICS95, FSV25, FTA7, FSA13, FSV155, FLE2, TSH565; and low (≤25%): FEAR5, FSV80, FMAC11, FYC2, FSA11, FEC44, FSV153, FLE28, FEC2, FEC7, FQUIP1.

Detecting life on Mars through the study of organic host Mars analogues and Urey instrument development
Creators: name: Marlow, Jeffrey
Publisher: name: Imperial College London

description: The search for life on Mars is one of today’s most exciting and far-reaching scientific challenges. The European Space Agency’s ExoMars mission will renew the pursuit of signs of past or present life equipped with a range of analytical instruments: one such instrument will likely be Urey, a tool that will extract and analyze organic molecules. This thesis first seeks to contextualize the search for life through the use of analogue sites on Earth and ultimately works to optimize the spectrofluorometric detection of relevant organic molecules. Organic host analogues – sites on Earth where life faces similar challenges as potential martian life forms – aid in mission planning and data analysis. With these dual purposes in mind and the understanding that collaborative analogue use benefits all stakeholders, the Imperial College Mars Analogue Repository (ICMAR) was established. Samples from Iceland and the Middle Atlas mountains of Morocco were gathered to start the collection. As it grows, mission planners and scientists will have a centralized, well-characterized set of samples for astrobiological studies. Optimizing Urey’s spectrofluorometric detection of amino acids and polycyclic aromatic hydrocarbons (PAHs) was another primary aim of this study. Standard solutions were tested across a range of instrumental parameters and an ideal excitation wavelength was identified to optimize the detection of any organics present at the sampling site. The fluorescent interaction between molecules was also investigated to evaluate the instrument’s ability to detect and quantify complicated, multicomponent samples. Finally, natural organic-rich samples from England’s Blue Lias formation were tested to evaluate spectrofluorometric analysis of natural samples – a capability that will be crucial for in situ martian analysis. By highlighting the role of organic Mars analogues and optimizing the Urey instrument, this thesis enhances ExoMars’ ability to identify organic molecules and sets the stage for continued martian exploration.

Experimental techniques for investigating lubricated, compliant contacts
Creators: name: Myant, Connor William
Publisher: name: Imperial College London
Year: 2010

description: The study of Tribology between soft or compliant surfaces is not well understood despite its importance to many biological and engineering applications, ranging from synovial joints to rubber o-ring seals. It has also been shown that the science of Tribology and lubrication in compliant contacts is an important factor in the sensory perception and functionality of skin, hair and the oral cavity, and so has an immediate application of the design of consumer products such as skin creams, hair conditioners and foodstuffs. This thesis aims to improve our understanding of thin film lubrication between soft, deformable surfaces under light loading and low-pressure conditions. The primary focus of the thesis is the development of techniques by which to measure the film thickness between compliant surfaces, from the nano- to the micro-scale. Several experimental techniques currently exist for measuring film thickness in hard, metallic contacts and these are widely employed in Tribology research of engineering systems. However they require considerable modification to be applicable to compliant contacts. This thesis describes the development of two such techniques; · a optical interferometric technique; for measuring nano-scale thicknesses in compliant contacts; · a laser induced fluorescence technique; developed to enable measurement of lubricant thickness of relatively thick films in compliant contacts.
