description: The isobaric multiplet mass equation (IMME) is known to break down in the first T = 2, A = 32 isospin quintet. In this work we combine high-resolution experimental data with state-of-the-art shell-model calculations to investigate isospin mixing as a possible cause for this violation. The experimental data are used to validate isospin-mixing matrix elements calculated with newly developed shell-model Hamiltonians. Our analysis shows that isospin mixing with nonanalog T = 1 states contributes to the IMME breakdown, making the requirement of an anomalous cubic term inevitable for the multiplet.

title: Determinants of survival and virulence of Campylobacter
Creators: name: Harvey, Philippa Caroline
Publisher: name: The Open University
Year: 2000

description: The pathogenesis of Campylobacter enteritis is not well understood including the mechanisms involved in invasion and translocation across intestinal epithelial cells. The genetic make-up of the pathogen and its responses to different environmental cues are thought to contribute to the organism's ability to survive and cause disease. The extremes of environment which Campylobacter can with-stand, and the effect that this has on virulence and invasive ability remains undefined. For the first time, several isolates were compared quantitatively to determine the extent to which intracellular invasion contributes to translocation across epithelial cell mono layers. Translocation ability did not correlate with intracellular invasiveness, suggesting that different "invasion" phenotypes exist among Campylobacter isolates. Repeated exposure of Campylobacter isolates to Caco-2 cells caused an increase in their ability to invade and survive, which was associated with changes in protein expression. Campylobacter was grown in continuous culture under conditions of iron sufficiency, iron limitation, oxidative stress and low pH. Uniquely, growth under oxidative stress and iron replete conditions caused an increase in the invasive ability of C. jejuni 81116, which was correlated with the up-regulation of specific proteins. The role of three proteins, HtrB, Tpx and PEB-4, was investigated at the molecular level. Two of the encoding genes, peb4A and htrB, were found to be essential for viability. Homologous recombination of an inactivated Ipx gene into the genome of C. jejuni caused increased sensitivity to H20 2, but did not affect the ability of C. jejuni to invade and survive within Caco-2 cell monolayers. This study demonstrated that isolates of Campylobacter differ significantly in their virulence potential with respect to their invasive phenotypes. In addition Campylobacter grown in well defined continuous culture conditions demonstrated for the first time the importance of iron and oxidative stress as acting as potenital cues for the expression of survival and invasion determinants.
title: Acid rain links to CH4 emissions from wetlands
Creators: name: Gauci, Vincent
Publisher: name: The Open University

description: A variety of approaches, spanning a range of spatial and temporal scales, were applied to the investigation of the effects of low dose SO42- deposition, at rates comparable to those experienced in acid rain impacted areas, on methane (CH4) emissions from natural wetlands.

Over two years of experimental manipulation of SO42- deposition to a peatland in northeast Scotland, CH4 emissions were suppressed by around 40%. There was no significant difference in suppression of CH4 flux within the sol- deposition range of 25-100 kg-S ha-1yr-1. In a similar short-term controlled environment SO42- manipulation experiment, the suppressive effect of SO42- was found to be independent of the simulated SO42- deposition rate within a range of 15-100 kg-S ha-1yr-1. The possibility that suppression of CH4 fluxes may have been the result of a 'salt effect' was ruled out. Both temperature and water table controlled the extent of CH4 flux suppression in acid rain impacted wetlands.

Sulfate reduction potential in SO42- treatments were found to be 10 times larger than in control plots, suggesting that long-term suppression of CH4 fluxes is the result of the formation of an enlarged population of competitively superior sulfate reducing bacteria.

 SO42- concentrations were smaller in peat pore water from SO42- treatments than from controls. This is possibly the result of a stimulated SO42- reducing community scavenging available SO42-, thereby decreasing concentrations to below ambient levels. In northern peatlands (>50°) the effect of SO42- deposition at 1990 rates may have been sufficient to reduce emissions from these systems by around 15% annually. Globally, the effect of acid rain SO42- deposition may be sufficient to reduce CH4 emissions by as much as 22-28 Tg by 2030, which places this interaction within the same size category as many other components of the global CH4 budget that have received far greater attention.
The Pliocene and Pleistocene fluvial evolution in the northern Upper Rhine Graben based on results of the research borehole at Viernheim (Hessen, Germany)

description: Die 2006 durch das Hessische Landesamt für Umwelt und Geologie (HLUG) abgeteufte Forschungsbohrung nördlich von Viernheim (Hessisches Ried) hat mit einer Endteufe von 350 m hoch aufgelöst fluviatile und limnisch-fluviatile Sedimente (0 bis 225 m) des Pleistozäns und zum Teil stark pedogen überprägte limnisch-fluviatile Sande, Tone und Schluffe des Pliozäns (225 bis 350 m) durchteuft. Die Liefergebiete der pliozänen Sedimente sind eher regional geprägt. Die Sedimente zeigen wiederholt Schüttungen aus dem Odenwald, die durch einen hohen Anteil grüner Hornblende in der Schwermineralfraktion gekennzeichnet sind. Als Teil des Forschungsprogramms „Heidelberger Becken“ zielte diese Bohrung insbesondere im Pleistozän auf die „Normalfazies“ des nördlichen Oberrheingrabens ab, das heißt: auf eine möglichst ungestörte Sedimentabfolge, die im Pleistozän Schüttungen von den Grabenrändern oder kleineren Zuflüssen weitestgehend ausschließt. Die pleistozäne Sedimentabfolge besteht aus drei Einheiten: über einem geringmächtigen Horizont mit aufgearbeitetem pliozänen Material folgen zehn Zyklen, die erosiv mit kiesig sandigen Sedimenten einsetzen und mit schluffig-tonigen bis zum Teil torfigen Ablagerungen abschließen. Mitunter sind interne Zyklen zu erkennen. Charakteristisch sind grünlich-graue stark carbonatische, glimmerführende und gut sortierte Fein- bis Mittelsande des Rheins. In diesen dominiert die Rhein-Gruppe (Granat, Epidot, grüne Hornblende und Alterit) in der Schwermineralfraktion. Diese Sedimente werden als „Rheinische Fazies“ bezeichnet. In der hangenden letzten pleistozänen Sedimentabfolge der Forschungsbohrung Viernheim bestimmen mehrere fining-upward und zum Teil coarsening-upward Sequenzen das Sedimentationsgeschehen. Die Ablagerungen dieses Profilabschnitts sind Kies dominiert, der vom Neckar geschüttet worden ist. Die Schwermineralverteilung der Sandfraktion zeigt aber an, dass es zu einer Vermischung mit rheinischen Sedimenten gekommen ist. Weichsel- bis holozänzeitliche Flugsande schliessen das Profil ab. Die stratigraphische Einstufung der pleistozänen Sedimentabfolge ist in Teilen noch unsicher. Die Pliozän-Pleistozängrenze wird auf Grund des charakteristischen Fazieswechsels auf 225 m gelegt. Eine überregionale Korrelation mit Sedimenten der Niederrheinischen Bucht spricht für eine Diskordanz mit größerer zeitlicher Lücke an der Plio-Pleistozängrenze. Untersuchungen im Umfeld der Bohrung sprechen für cromerzeitliches Alter des jüngsten feinklastischen Abschnitts der Bohrung zwischen 39,76 und 58,55 m.

description: Distances and absolute ages for the globular clusters NGC6397, NGC6752, and 47 Tuc are obtained using Main Sequence Fitting. Accurate reddenings and metal abundances (errors of 0.005 mag and 0.04 dex) are obtained by comparing B-V, b-y colours and UVES spectra for clusters TO-stars and subgiants with similar data for Hipparcos subdwarfs, using a reddening free temperature indicator (Halpha). Errors in distances and ages are 0.07 mag and 1 Gyr. NGC6397 and NGC6752 have ages of 13.5\pm 1.1 and 13.4\pm 1.1 Gyr, while 47 Tuc is probably about 2.6 Gyr younger, in agreement with results obtained by techniques sensitive to relative ages. Considering possible systematic errors, the age of the oldest globular clusters is 13.4\pm 0.8\pm 0.6 Gyr (random and systematic errors). This age is fully compatible with WMAP results, and indicates that the oldest Galactic globular clusters formed within the first 1.7 Gyr after the Big Bang, corresponding to a redshift of z\geq 2.5, in a standard LambdaCDM model. The epoch of formation of the (inner halo) globular clusters lasted about 2.6 Gyr, ending at a time corresponding to a redshift of z\geq 1.3. Once combined with values of Ho given by WMAP and by the HST Key Project, our age estimate provides a robust upper limit at 95% level of confidence of Omega_M<0.57, indicating the need for a vacuum energy independent of results from type Ia SNe and clusters of galaxies. Using cluster distances, we derive a value of M_V(HB)=(0.22\pm 0.05)([Fe/H]+1.5)+(0.56\pm 0.07) for the zero point of the relation between the horizontal branch absolute magnitude and metallicity. When combined with the apparent average luminosity of the RR Lyrae stars in the LMC by Clementini et al. (2003), this zero point provides a new estimate of the distance modulus to the LMC: (m-M)o=18.50\pm 0.09.

title: People with learning disabilities' accounts of friendship
Creators: name: Gathard, Jo
Publisher: name: The Open University
Year: 2000

description: This study aimed to investigate how people with learning disabilities construct accounts of friendship, and manage aspects of a 'spoiled identity' within this. Furthermore it aimed to investigate how the typical processes of friendship formation are affected by the management of such an identity. It was suggested disclosure of personal information can be anxiety provoking for them and the choice of analysis needed to focus on deconstructing their accounts for linguistic devices used to manage difficult issues and then consideration could be given to the functions of these devices. Eight people with mild learning disabilities, four men and four women, were recruited to the study. Having obtained their informed consent each was interviewed using a semi-structured interview schedule focusing upon aspects of friendship formation identified within mainstream literature. In view of the aims of the study it was decided the most appropriate form of analysis would be discourse analysis. At a surface level the experience of the participants mirrored that found in previous research. In addition a number of rhetorical devices were identified. Further consideration of these revealed they were used at times in the interview when either participant or interviewer was attempting to manage an issue related to difference or stigma. In view of this it is argued that managing a stigmatised identity directly impacts upon typical processes of friendship formation. The findings are discussed; consideration is given to service and research implications. It is suggested that awareness of the nature and function of rhetorical devices could facilitate professionals in helping people with learning disabilities to discuss their difficulties and associated emotions in a more meaningful way. Enabling people with learning disabilities to develop higher self-esteem is discussed in relation to them attributing more value to friendships with others with similar disabilities, and the development of the self-advocacy movement.

description: In the search for superheavy elements quasifission reactions represent one of the reaction pathways that curtail the formation of an evaporation residue. In addition to its importance in these searches quasifission is also an interesting dynamic process that could assist our understanding of many-body dynamical shell effects and energy dissipation thus forming a gateway between deep-inelastic reactions and fission. This manuscript gives a summary of recent progress in microscopic calculations of quasifission employing time-dependent Hartree-Fock (TDHF) theory and its extensions.

description: In this letter, we study the leader-synchronization problem for a class of partial differential equations with boundary control and in-domain coupling. We describe the problem in an abstract formulation and we specialize it to a network of parabolic partial differential equations. We consider a setting in which a subset of the followers is connected to the leader through a boundary control, while interconnections among the followers are enforced by distributed in-domain couplings. Sufficient conditions in the form of matrix inequalities for the selection of the control parameters enforcing exponential synchronization are given. Numerical simulations illustrate and corroborate the theoretical findings.

description: The simulation of long, nonlinear dispersive waves in bounded domains usually requires the use of slip-wall boundary conditions. Boussinesq systems appearing in the literature are generally not well-posed when such boundary conditions are imposed, or if they are well-posed it is very cumbersome to implement the boundary conditions in numerical approximations. In the present paper a new Boussinesq system is proposed for the study of long waves of small amplitude in a basin when slip-wall boundary conditions are required. The new system is derived using asymptotic techniques under the assumption of small bathymetric variations, and a mathematical proof of well-posedness for the new system is developed. The new system is also solved numerically using a Galerkin finite-element method, where the boundary conditions are imposed with the help of Nitsche's method. Convergence of the numerical method is analyzed, and precise error estimates are provided. The method is then implemented, and the convergence is verified using numerical experiments. Numerical simulations for solitary waves shoaling on a plane slope are also presented. The results are compared to experimental data, and excellent agreement is found.

description: Aún son escasos los estudios sobre el español de la comunidad sefardí italiana en documentación diplomática. En este trabajo, por un lado, se analiza la modalidad lingüística presente en cuatro inventarios inéditos localizados en Pisa, que no se puede calificar de judeoespañol sino de un español afín al peninsular en la antesala de la inminente asimilación lingüística al italiano; en este sentido, se analiza la conexión lingüística con la Península Ibérica, las formas léxicas crudas y adaptadas de procedencia italiana: arcaísmos y regionalismos, italianismos morfosintácticos y léxico-semánticos, arabismos y galicismos que entran por vía italiana; además de los xenismos hebreos, circunscritos a la administración, la religión y los ritos, y de los elementos hispánicos no castellanos). Por otra parte, tras señalar su indiscutible valor social, se propone una presentación crítica de estos documentos, fechados en Pisa en 1681 los tres primeros (Inventario de efectos y ropas de las casas de David de Mesa y Samuel de Chaves, Inventario de la botica de Jacob Blandón e Inventario de la casa de Jacob Blandón) y el cuarto en 1686 (Inventario de los bienes de Abraham Cardoso), siguiendo los criterios de edición de CHARTA, y continuando la línea empezada por Manuel Ariza de edición de documentos notariales de Pisa del siglo XVII en 2012, dentro del grupo de investigación “La lengua española en su historia” (HUM 111) dirigido en ese momento por el catedrático de la Universidad de Sevilla Manuel Ariza Viguera. Previamente, se había participado en el 18º Congreso de Estudios Sefardíes, organizado por el CSIC y celebrado en Madrid en 2014, con una comunicación titulada “De nuevo sobre el judeo-español de Pisa (S. XVII)”, en coautoría con el investigador José Javier Rodríguez Toro, quien también, por su parte, ha publicado investigaciones acerca de esta temática. El artículo, posteriormente, dio lugar a una visita con fines de investigación al Archivo de la Comunidad Hebraica de Pisa en diciembre de 2017, en la que se llevó a cabo una recopilación de documentación manuscrita, cuyo estudio, a su vez, se dio a conocer en una ponencia invitada en las II Jornadas Internacionales "Los sefardíes y sus textos”, celebradas en la Universidad de Sevilla en 2018, que llevó por título “La(s) lengua(s) de los sefardíes pisanos de finales del XVII”.

description: We have applied a model of planetary system formation in the field of a standing sound wave (the ‘SSW-Model’) to the prediction of planets in 586 multi-planetary exosystems (384 biplanetary, 127 tri-planetary and 75 exosystems with four or more confirmed planets). We have verified our predictions using transit-like events from the NASA Threshold-Crossing Event (TCE) catalogue, finding that more than 80% of these events are included in our list of exoplanet predictions. We describe a method for predicting the periods and semi-major axes of additional planets for exosystems with two or more confirmed planets. Our method can significantly facilitate targeted searches for planets in exosystems, enabling the detection of many new exoplanets, including those located in the habitable zones.

title: The development of writing in four to seven year-old children: a longitudinal study
Creators: name: Dunsmuir, Sandra Murray
Publisher: name: The Open University
Year: 2001

description: This longitudinal study investigates the factors at home and school that influence children's attainment and progress in writing at Key Stage 1. Sixty children between the ages of four and seven years in four Reading primaiy schools were tracked and data was collected in the term before they started school, at school entry, on a termly basis once in school and at the end of Key Stage 1. Semi-structured interviews, questionnaires, observation schedules, checklists and standardised assessments were used. Associations between measures and continuity over time were assessed using multiple regression analysis. Pre-school independent variables that were found to be significantly associated with writing proficiency at school entry included mother's educational level, family size, parental assessment of writing and a measure of home writing. Child characteristics, skills and competencies were measured at school entry and those found to be significantly associated with writing at outcome included season of birth, WPPSI-R vocabulary score, pre-reading skills and proficiency in writing their own name. The only pre-school variable that maintained its significant relationship to writing at outcome was home writing. Teacher assessments of pupil attitudes to writing were consistently found to be significantly associated with writing at outcome. Data from the termly writing samples indicated that only the handwriting assessment predicted general writing ability at seven years of age. Eight pupils were observed writing at two points in time and the records are discussed in terms of processes and products. Issues such as quality and quantity of writing generated are considered in relation to the development of component skills (e.g. handwriting, spelling, vocabulary), within the context of the curriculum and role of the teacher. The results confirm the complexity of learning to write for children at Key Stage I and developmental considerations are discussed in relation to policy and practice issues.

description: The semiclassical Coulomb excitation interaction is at times expressed in the Lorentz gauge in terms of the electromagnetic fields and a contribution from the scalar electric potential. We point out that the potential term can make spurious contributions to excitation cross sections, especially when the the decay of excited states is taken into account. We show that, through an appropriate gauge transformation, the excitation interaction can be expressed in terms of the electromagnetic fields alone.

description: Several works reported increased differentiation of neuronal cells grown on graphene; however, the molecular mechanism driving axon elongation on this material has remained elusive. Here, we study the axonal transport of nerve growth factor (NGF), the neurotrophin supporting development of peripheral neurons, as a key player in the time course of axonal elongation of dorsal root ganglion neurons on graphene. We find that graphene drastically reduces the number of retrogradely transported NGF vesicles in favor of a stalled population in the first two days of culture, in which the boost of axon elongation is observed. This correlates with a mutual charge redistribution, observed via Raman spectroscopy and electrophysiological recordings. Furthermore, ultrastructural analysis indicates a reduced microtubule distance and an elongated axonal topology. Thus, both electrophysiological and structural effects can account for graphene action on neuron development. Unraveling the molecular players underneath this interplay may open new avenues for axon regeneration applications.
Observational constraints on braneworld chaotic inflation

description: We examine observational constraints on chaotic inflation models in the Randall-Sundrum Type II braneworld. If inflation takes place in the high-energy regime, the perturbations produced by the quadratic potential are further from scale-invariance than in the standard cosmology, in the quartic case more or less unchanged, while for potentials of greater exponent the trend is reversed. We test these predictions against a data compilation including the WMAP measurements of microwave anisotropies and the 2dF galaxy power spectrum. While in the standard cosmology the quartic potential is at the border of what the data allow and all higher powers excluded, we find that in the high-energy regime of braneworld inflation even the quadratic case is under strong observational pressure. We also investigate the intermediate regime where the brane tension is comparable to the inflationary energy scale, where the deviations from scale-invariance prove to be greater.

description: Non-Hermiticity can destroy Anderson localization and lead to delocalization even in one dimension. However, the unified understanding of the non-Hermitian delocalization has yet to be established. Here, we develop a scaling theory of localization in non-Hermitian systems. We reveal that non-Hermiticity introduces a new scale and breaks down the one-parameter scaling, which is the central assumption of the conventional scaling theory of localization. Instead, we identify the origin of the unconventional non-Hermitian delocalization as the two-parameter scaling. Furthermore, we establish the threefold universality of non-Hermitian localization based on reciprocity; reciprocity forbids the delocalization without internal degrees of freedom, whereas symplectic reciprocity results in a new type of symmetry-protected delocalization.

Adaptive and Multiple Time-scale Eligibility Traces for Online Deep Reinforcement Learning

description: Deep reinforcement learning (DRL) is one promising approach to teaching robots to perform complex tasks. Because methods that directly reuse the stored experience data cannot follow the change of the environment in robotic problems with a time-varying environment, online DRL is required. The eligibility traces method is well known as an online learning technique for improving sample efficiency in traditional reinforcement learning with linear regressors rather than DRL. The dependency between parameters of deep neural networks would destroy the eligibility traces, which is why they are not integrated with DRL. Although replacing the gradient with the most influential one rather than accumulating the gradients as the eligibility traces can alleviate this problem, the replacing operation reduces the number of reuses of previous experiences. To address these issues, this study proposes a new eligibility traces method that can be used even in DRL while maintaining high sample efficiency. When the accumulated gradients differ from those computed using the latest parameters, the proposed method takes into account the divergence between the past and latest parameters to adaptively decay the eligibility traces. Bregman divergences between outputs computed by the past and latest parameters are exploited due to the infeasible computational cost of the divergence between the past and latest parameters. In addition, a generalized method with multiple time-scale traces is designed for the first time. This design allows for the replacement of the most influential adaptively accumulated (decayed) eligibility traces.

On the Mass and Magnetic Field of the Neutron Star in the Ultraluminous X-Ray Source NGC 300 ULX1

description: The accreting compact objects in most of ultraluminous X-ray sources (ULXs) are likely to be neutron stars rather than black holes as suggested by the recent detection of periodic pulsations from some of these sources located in neighboring galaxies and one ULX that has hitherto been discovered in our own galaxy. As a member of the ULX family, NGC 300 ULX1 is a new pulsating ULX (PULX) spinning up at substantially high rates compared with other PULXs. In this paper, the strength of the magnetic field on the surface of the neutron star is inferred from the energy of the cyclotron absorption line detected in the pulsed X-ray spectrum of NGC 300 ULX1 and the plausible ranges for the neutron-star mass and beaming fraction are estimated using the observed spin period and period derivative of the pulsar and the measured X-ray flux of the source. Our analysis favors proton cyclotron resonance scattering as a viable mechanism to account for both the observed cyclotron energy and high spin-up rates provided that the absorption line is generated close to the surface of the neutron star.

description: Prolonged dry periods are occurring with increasing frequency during the growing season due to climate change. Irrigation is, therefore, becoming more important for the improved exploitation of crop yield potential. The choice of a suitable irrigation system depends on various factors such as the crop to be irrigated, availability of water, soil condition, and topography, availability of technical and financial resources, as well as technical know-how, and manpower availability. Three widespread irrigation methods of mobile, fixed and micro irrigation have been analysed in the geographical areas of Germany and Switzerland concerning their working time requirement for transport, assembly, operation, and dismantling. The working hours and the influencing variables were statistically analysed and integrated in a model calculation system. The results showed the working time requirement for the selected irrigation methods under modelled conditions. Regarding the required manpower, for a 1 ha plot, hose reel irrigators required 1.8 h, pipe sprinklers 9.5 h and drip irrigation systems 12.3 h total working time.

description: It is expected that the quantum nature of spacetime leaves its imprint in all semiclassical gravitational systems, at least in certain regimes, including gravitational waves. In this paper we investigate such imprints on gravitational waves within a specific framework: space is assumed to be discrete (in the form of a regular cubic lattice), and this discrete geometry is quantised following Dirac's canonical quantisation scheme. The semiclassical behavior is then extracted by promoting the expectation value of the Hamiltonian operator on a semiclassical state to an effective Hamiltonian. Considering a family of semiclassical states representing small tensor perturbations to Minkowski background, we derive a quantum-corrected effective wave equation. The deviations from the classical gravitational wave equation are found to be encoded in a modified dispersion relation and controlled by the discreteness parameter of the underlying lattice. For finite discretisations, several interesting effects appear: we investigate the thermodynamical properties of these modified gravitons and, under certain assumptions, derive the tensor power spectrum of the cosmic microwave background. The latter is found to deviate from the classical prediction, in that an amplification of UV modes takes place. We discuss under what circumstances such effect can be in agreement with observations.

Anhand der Auswertung topographischer Karten und Luftbilder wird diese Entwicklung für den Zeitraum der letzten 250 Jahre für das Gebiet des heutigen Naturschutzgebietes Huvenhoopsmoor im Landkreis Rotenburg (Wümme) im nördlichen Niedersachsen nachgezeichnet.
description: In Europe hardly no landscape has changed so substantially as the peatlands did during the last centuries. Melioration and land use resulted in massive changes of the peatland-ecosystems. For the period of the last 250 years for the nature reserve Huvenhoopsmoor, district of Rotenburg (Wümme), northern Lower Saxony, this development is shown by the interpretation of topographic maps and aerial photographs.
