description: We study colloidal gels formed by competing electrostatic repulsion and short-range attraction by means of extensive numerical simulations under external shear. We show that, upon varying the repulsion strength, the gel structure and its viscoelastic properties can be largely tuned. In particular, the gel fractal dimension can be either increased or decreased with respect to mechanical equilibrium conditions. Unexpectedly, gels with stronger repulsion, despite being mechanically stiffer, are found to be less viscous with respect to purely attractive ones. We provide a microscopic explanation of these findings in terms of the influence of an underlying phase separation. Our results allow for the design of colloidal gels with desired structure and viscoelastic response by means of additional electrostatic interactions, easily controllable in experiments.

Physodoceras wolfi

description: Physodoceras cf. wolfi (Neumayr, 1873) (Fig. 12A)
MATERIAL EXAMINED. — MI4N 8c/3.
STRATIGRAPHIC DISTRIBUTION. — The specimen has been collected in bed 8c of section Monte Inici East, assigned with doubt to the Hauffianum Subzone of the Late Oxfordian Bimammatum Zone.
DESCRIPTION
 Moderately evolute shell, with a deep umbilicus and a large whorl section. Whorl flanks are almost flat and converge towards a rounded, large venter. The umbilical wall is steep and the umbilical margin is rounded. Due to crushing, the whorl section is not correctly observable in the body chamber. The ornamentation is made of small, rounded, periumbilical tubercles. The suture line is characterized by L as deep as E and S 1 slightly higher than S 2. Measurements: see Table 21.
DISCUSSION
 The preservation does not allow a firm identification of this specimen. A similar species is P. insulanum (Gemmellaro, 1874), which has been considered synonym of P. wolfi by Checa (1985). In the recent revision of the Gemmellaro species, D’Arpa & Meléndez (2002) keep the latter distinct from P. wolfi because of the wider whorl-breadth and the stronger tubercles. The characters visible in the phragmocone of our specimen suggest the comparison with P. wolfi.

description: This note points out to applied researchers what adjustments are needed to the coefficient estimates in a random effects probit model in order to make valid comparisons in terms of coefficient estimates and marginal effects across different specifications. These adjustments are necessary because of the normalisation that is used by standard software in order to facilitate easy estimation of the random effects probit model.
Hopf Bifurcation from new-Keynesian Taylor rule to Ramsey Optimal Policy

description: This paper compares different implementations of monetary policy in a new-Keynesian setting. We can show that a shift from Ramsey optimal policy under short-term commitment (based on a negative feedback mechanism) to a Taylor rule (based on a positive feedback mechanism) corresponds to a Hopf bifurcation with opposite policy advice and a change of the dynamic properties. This bifurcation occurs because of the ad hoc assumption that interest rate is a forward-looking variable when policy targets (inflation and output gap) are forward-looking variables in the new-Keynesian theory.

description: We propose a one-dimensional model of a string decorated with adhesion molecules (stickers) to mimic multicomponent membranes in restricted geometries. The string is bounded by two parallel walls and it interacts with one of them by short range attractive forces while the stickers are attracted by the other wall. The exact solution of the model in the case of infinite wall separation predicts both continuous and discontinuous transitions between phases characterised by low and high concentration of stickers on the string. Our model exhibits also coexistence of these two phases, similarly to models of multicomponent membranes.

Impact of Interparticle Interaction on Thermodynamics of Nano-Channel Transport of Two Species

description: We present a rigorous mathematical approach of two species channel transport within the framework of stochastic thermodynamics, which explains the impact of interparticle in-channel interactions. Different from mean field approaches, the model explicitly conserves spatial correlations by considering stochastic transitions between the channel's occupation states. The interparticle interactions determine the Brownian ratchet like rectifying forces, which these species exert mutually on each other. Perfect coupling of transport emerges by an attractive empty channel and strong repulsive forces between particles of the same species. Stochastic transitions are then confined to a subspace with circular topology, which makes channel flows of both species become equivalent. For opposing concentration gradients, this makes the species with the stronger gradient the driving, positive entropy producing one, the other is driven and produces negative entropy. A differential interaction with less repulsive forces within particles of one species, but maintenance of this interaction for the other species, adds a bypass path to this circular subspace. On this path a leak flow of the species with less repulsive interparticle interaction emerges, which is directed parallel to its concentration gradient, and, hence, produces positive entropy. Now, appropriate strong opposing concentration gradients may simultaneously parallelize flow of their respective species, which makes each species produce positive entropy. The rectifying potential of the species with the bypass option is diminished, which implies the existence of a gradient of the other species, above which its flow and gradient are always parallel. Conversely flow of the less coupled species may always be turned anti-parallel to its gradient by a sufficient strong opposing gradient of the other one.

description: We have analyzed Chandra archival observations of the Antennae galaxies to study the distribution and physical properties of its hot interstellar gas. Eleven distinct diffuse X-ray emission regions are selected according to their underlying interstellar structures and star formation activity. The X-ray spectra of these regions are used to determine their thermal energy contents and cooling timescales. Young star clusters in these regions are also identified and their photometric measurements are compared to evolutionary stellar population synthesis models to assess their masses and ages. The cluster properties are then used to determine the stellar wind and supernova energies injected into the ISM. Comparisons between the thermal energy in the hot ISM and the expected stellar energy input show that young star clusters are sufficient to power the X-ray-emitting gas in some, but not all, active star formation regions. Super-star clusters, with masses >= 1x10^5 M_sol, heat the ISM, but the yield of hot interstellar gas is not directly proportional to the cluster mass. Finally, there exist diffuse X-ray emission regions which do not show active star formation or massive young star clusters. These regions may be powered by field stars or low-mass clusters formed within the last ~100 Myr.

description: Thermal comfort is a personal assessment of one's satisfaction with the surroundings. Yet, most thermal comfort delivery mechanisms preclude physiological and psychological precursors to thermal comfort. Accordingly, many people feel either cold or hot in an environment that is supposedly thermally comfortable to most people. To address this issue, this paper proposes to use people's heart rate variability (HRV) as an alternative indicator of thermal comfort. Since HRV is linked to homeostasis, we hypothesize that it could be used to predict people's thermal comfort status. To test our hypothesis, we analyzed statistical, spectral, and nonlinear HRV indices of 17 human subjects doing light office work in a cold, a neutral, and a hot environment. The resulting HRV indices were used as inputs to machine learning classification algorithms. We observed that HRV is distinctively altered depending on the thermal environment and that it is possible to steadfastly predict each subject's thermal environment (cold, neutral, and hot) with up to a 93.7% prediction accuracy. The result of this study implies that it could be possible to design automatic real-Time thermal comfort controllers based on people's HRV.

description: This paper presents a small macroeconometric model examining the determinants of Indian trade and inflation to address the effects of a reform policy package similar to those implemented in 1991. This is different from previous studies along one important dimension that we explicitly incorporate the non-stationarity of the data into our model and estimation procedures, which suggest that the stationarity assumption may be a source of misspecification in previous work. So the model has been estimated using the data from 1950 to 1995 employing fully-modified Phillips-Hansen Method of estimation to obtain the cointegrating relations and short-run dynamic model. Policy simulations using dynamic simulations method compare the dynamic responses to devaluation with the responses to tight credit policy. It is shown that the trade balance effects of tight credit policy are more enduring than those of devaluation. The simulations demonstrate that the devaluation has actually worsened the trade balance and hence devaluation is not an option in response to a negative trade shock, whereas the reduction in domestic credit produces a desirable improvement in the trade balance.

description: This paper investigates long-run relationships among the spot prices of four coffee types. We find two cointegrating vectors: one between the prices of Other Milds and Colombian coffee, and the other one between Unwashed Arabicas and Robustas. Following Pesaran and Shin (1996), persistence profile analysis of the two cointegrating vectors shows a rapid adjustment towards their equilibrium value. This suggests that the four coffee markets are highly related, and that discrepancies in the equilibrium relationships are short-lived. Out of sample evaluation of the model is reasonably good, except for two occasions of sharp price increases following adverse weather conditions

description: We consider a dynamical system given by an area-preserving map on a two-dimensional phase plane and consider a one-dimensional line of initial conditions within this plane. We record the number of iterates it takes a trajectory to escape from a bounded region of the plane as a function along the line of initial conditions, forming an ``escape-time plot''. For a chaotic system, this plot is in general not a smooth function, but rather has many singularities at which the escape time is infinite; these singularities form a complicated fractal set. In this article we prove the existence of regular repeated sequences, called ``epistrophes'', which occur at all levels of resolution within the escape-time plot. (The word ``epistrophe'' comes from rhetoric and means ``a repeated ending following a variable beginning''.) The epistrophes give the escape-time plot a certain self-similarity, called ``epistrophic'' self-similarity, which need not imply either strict or asymptotic self-similarity.

If it is possible to charge for the time spent using the public good it is generally a second-best Pareto optimal policy to do so even in the absence of congestion. An optimal linear user charge is analysed within a standard optimum income-tax framework. Second-best public good provision in the presence of a user charge is also characterized and factors that in‡uence the direction of optimal distortion of the public good supply are identi…ed.

Quasi-wetting and morphological phase transitions in confined far-from-equilibrium magnetic thin films

description: The growth of confined magnetic films with ferromagnetic interactions between nearest-neighbor spins is studied in a stripped $(1+1)-$dimensional rectangular geometry. Magnetic films are grown irreversibly by adding spins at the boundaries of the growing interface. A competing situation with two opposite short range surface magnetic fields of the same magnitude is analyzed. Due to the antisymmetric condition considered, an interface between domains with spins having opposite orientations develops along the growing direction. Such interface undergoes a localization-delocalization transition that is identified as a quasi-wetting transition, in qualitative agreement with observations performed under equilibrium conditions. In addition, the film also exhibits a growing interface that undergoes morphological transitions in the growth mode. It is shown that, as a consequence of the nonequilibrium nature of the investigated model, the subtle interplay between finite-size effects, wetting, and interface growth mechanisms leads to more rich and complex physical features than in the equilibrium counterpart. Indeed, a phase diagram that exhibits eight distinct regions is evaluated and discussed. In the thermodynamic limit, the whole ordered phase (which contains the quasi-wetting transition) collapses, while within the disordered phase, standard extrapolation procedures show that only two regions are present in the phase diagram of the infinite system.

title: Active and Adoptive Immunotherapy in Indolent Lymphoproliferative Diseases
Creators: name: Zappasodi, Roberta
Publisher: name: The Open University
Year: 2011

description: Although monoclonal antibody (mAb) therapy has improved the outcome of low-grade B-cell non-Hodgkin lymphomas (B-NHL), they remain incurable diseases. The intimate relationship between immune cells and lymphomas for its maintenance and progression suggests that immunotherapy may represent a valuable strategy towards the control and eradication of these malignancies. Despite initial successes of anti-idiotype vaccination, its clinical benefits have not been definitely proven. New insights into the mechanisms whereby (i) tumour escape immunity, (ii) certain anticancer treatments exert immunogenic functions, (iii) microenvironment influences lymphoma growth should open new ways for immunotherapeutic intervention.

Towards this goal, dendritic cells (DCs) loaded with autologous killed tumour cells were used to immunize indolent B-NHL patients against a wide spectrum of tumour antigens, thereby enhancing the possibility of a clinical success. A significant correlation was observed between clinical responses and both regulatory T cell frequency decrease and natural killer cell activation. These effects were positively associated with calreticulin and heat shock protein (HSP)90 surface expression in dying tumour cells used in the vaccine formulations. Therapeutic improvements might thus be accomplished by stimulating tumour release of "eat-me” signals.

T-cell maturation and anti-lymphoma activation were also associated with a positive clinical outcome. A novel artificial expansion system was developed to boost these effects through the ex-vivo generation of functional, long-lasting polyclonal T cells and adoptive cell therapy.

Finally, the investigation of tumour-restricted humoral immunity in clinical responders permitted the serological identification of HSP105 as a novel potential NHL immunodominant antigen. HSP105 expression correlated with B-NHL proliferation and aggressiveness. A specific neutralizing Ab significantly reduced lymphoma burden in xenotransplanted mice, thus laying the basis for a novel passive immunotherapy for B-NHL.

Collectively, these results provide important information on mechanisms underlying anti-lymphoma immunity and open up the possibility of improving active and passive immunotherapy to the treatment of indolent B-NHLs.

description: This article is a pedagogical introduction to relativistic quantum mechanics of the free Majorana particle. This relatively simple theory differs from the well-known quantum mechanics of the Dirac particle in several important aspects. We present its three equivalent formulations. Next, so called axial momentum observable is introduced, and general solution of the Dirac equation is discussed in terms of eigenfunctions of that operator. Pertinent irreducible representations of the Poincaré group are discussed. Finally, we show that in the case of massless Majorana particle the quantum mechanics can be reformulated as a spinorial gauge theory.

description: We present an investigation of the influence of structural distortions in charge-carrier doped \lmco by substituting La$^{3+}$ with alkaline earth metals of strongly different ionic sizes, that is M = Ca$^{2+}$, Sr$^{2+}$, and Ba$^{2+}$, respectively. We find that both, the magnetic properties and the resistivity change non-monotonously as a function of the ionic size of M. Doping \lmco with M = Sr$^{2+}$ yields higher transition temperatures to the ferromagnetically ordered states and lower resistivities than doping with either Ca$^{2+}$ or Ba$^{2+}$ having a smaller or larger ionic size than Sr$^{2+}$, respectively. From this observation we conclude that the different transition temperatures and resistivities of \lmco for different M (of the same concentration $x$) do not only depend on the varying chemical pressures. The local disorder due to the different ionic sizes of La$^{3+}$ and M$^{2+}$ play an important role, too.

description: It has been hypothesized recently that core collapse supernovae are triggered by mildly relativistic jets following observations of radio properties of these explosions. Association of a jet, similar to a gamma-ray burst jet but only slower, allows shock acceleration of particles to high energy and non-thermal neutrino emission from a supernova. Detection of these high energy neutrinos in upcoming kilometer scale Cherenkov detectors may be the only direct way to probe inside these astrophysical phenomena as electromagnetic radiation is thermal and contains little information. Calculation of high energy neutrino signal from a simple and slow jet model buried inside the pre-supernova star is reviewed here. The detection prospect of these neutrinos in water or ice detector is also discussed in this brief review. Jetted core collapse supernovae in nearby galaxies may provide the strongest high energy neutrino signal from point sources.

title: The Impact of Retail Sector Delivery of Artemether-Lumefantrine on Effective Malaria Treatment of Children Under Five in Kenya
Creators: name: Kangwana, Beth Bonareri Pamba
Publisher: name: The Open University
Year: 2012

description: Background: With a low proportion of children receiving the first line treatment for suspected malaria, it has been proposed that artemisinin based combination therapy be subsidised in the private sector in order to improve affordability and access. This thesis presents an evaluation of a pilot subsidy mechanism in Western Kenya.

Methods: The primary objective was to evaluate the impact of providing subsidized artemether-lumefantrine (AL) through trained retailers, on the coverage of prompt effective anti-malarial treatment for febrile children aged three to 59 months. I used a cluster-randomised, controlled design with nine control and nine intervention sublocations, equally distributed across three districts. Provider, mystery shopper and household cross-sectional surveys were conducted at baseline and one year later. Data were analysed based on cluster-level summaries, comparing control and intervention arms, while adjusting for covariates. On average details of 2,706 children and 564 retail outlets were captured per year.

Results: Provider survey and mystery shopper data showed that at follow-up a significantly greater percentage of retailers stocked and dispensed AL, and knew that AL was the first line treatment for uncomplicated malaria in the intervention arm compared to the control. Significantly fewer retailers stocked antimalarial monotherapies. Household survey data showed that an average of 29% of children had experienced fever within the previous two weeks. Within this sample, the percentage receiving AL on the same day or following day of fever developing at follow-up was 25.0% points higher in the intervention arm than in the control arm, a statistically significant difference. However, adherence to dosing for AL purchased in the retail sector and advice given to caretakers by retailers remained unchanged post-intervention.

Conclusion: Overall, subsidizing ACTs in the retail sector can significantly increase ACT coverage in rural areas. Further research is needed on ways to improve counselling and adherence as well as on the impact and cost-effectiveness of such an intervention at a national scale.

description: A macroscopic Coulomb system of identical charged particles with or without a compensating background charge can evolve maintaining spatial homogeneity and isotropy that mimic the cosmological evolution of a universe with repulsive gravity. Here we study dynamics of small perturbations on the background of the corresponding Hubble flow by analyzing its normal modes of vibrations. Arbitrary disturbance of the flow can be resolved into two electro-acoustic, two vortical, and one entropic modes whose dynamics is investigated. Specifically, in the zero pressure or long-wavelength limits perturbations of density and velocity evolve in a manner that is independent of the form of the initial disturbance. The same conclusion applies to vortical perturbations of the velocity for arbitrary pressure while entropic perturbations are advected by the Hubble flow. Without the background charge the underlying Hubble flow describes a Coulomb explosion whose stability with respect to small disturbances is also demonstrated.

description: Context: In sunspots, the geometric height of continuum optical depth unity is depressed compared to the quiet Sun. This so-called Wilson depression is caused by the Lorentz force of the strong magnetic field inside the spots. However, it is not understood in detail yet, how the Wilson depression is related to the strength and geometry of the magnetic field or to other properties of the sunspot. Aims: We aim to study the dependence of the Wilson depression on the properties of the magnetic field of the sunspots and how exactly the magnetic field contributes to balancing the Wilson depression with respect to the gas pressure of the surroundings of the spots. Methods: Our study is based on 24 spectropolarimetric scans of 12 individual sunspots performed with Hinode. We derived the Wilson depression for each spot using both, a recently developed method that is based on minimizing the divergence of the magnetic field, and an approach developed earlier that enforces an equilibrium between the gas pressure and the magnetic pressure inside the spot and the gas pressure in the quiet Sun, thus neglecting the influence of the curvature force. We then performed a statistical analysis by comparing the Wilson depression resulting from the two techniques with each other and by relating them to various parameters of the sunspots, such as their size or the strength of the magnetic field. Results: We find that the Wilson depression becomes larger for spots with a stronger magnetic field, but not as much as one would expect from the increased magnetic pressure. This suggests that the curvature integral provides an important contribution to the Wilson depression, particularly for spots with a weak magnetic field. Our results indicate that the geometry of the magnetic field in the penumbra is different between spots with different strengths of the average umbral magnetic field.

description: In this paper, we show that Goodwillie calculus, as applied to functors from stable homotopy to itself, interacts in striking ways with chromatic aspects of the stable category. Localized at a fixed prime p, let T(n) be the telescope of a v_n self map of a finite S--module of type n. The Periodicity Theorem of Hopkins and Smith implies that the Bousfield localization functor associated to T(n) is independent of choices. Goodwillie's general theory says that to any homotopy functor F from S--modules to S--modules, there is an associated tower under F, {P_dF}, such that F --> P_dF is the universal arrow to a d--excisive functor. Our first theorem says that P_dF --> P_{d-1}F always admits a homotopy section after localization with respect to T(n) (and so also after localization with respect to Morava K--theory K(n)). Thus, after periodic localization, polynomial functors split as the product of their homogeneous factors. This theorem follows from our second theorem which is equivalent to the following: for any finite group G, the Tate spectrum t_G(T(n)) is weakly contractible. This strengthens and extends previous theorems of Greenlees--Sadofsky, Hovey--Sadofsky, and Mahowald--Shick. The Periodicity Theorem is used in an essential way in our proof. The connection between the two theorems is via a reformulation of a result of McCarthy on dual calculus.

title: Informality, Infrastructure and the State in Post-Apartheid Johannesburg
Creators: name: Wafer, Alex
Publisher: name: The Open University

description: The central argument of this thesis is that the spatiality of encounter between state and citizenship in post-apartheid South Africa is unequal and discontinuous. Although the developmental postapartheid state remains a powerful political narrative, the existence of what have been called 'informal' modes of association and organisation suggests that this imagination has not completely permeated post-apartheid society. Based on a case study of 'informal' street traders in inner city Johannesburg, I argue in this thesis that in fact a very particular state geography is emergent in post-apartheid South Africa: using a theoretical literature that includes state theory, govemmentality studies and critical post-colonial geography I suggest that mutual imaginations of state and citizenship intersect in particular nodes of encounter. In a context where the institutions of state have neither a coherent nor a singular view of everyday associational life in the city, the Johannesburg Metropolitan Municipality has developed a strategy of building formal market places in an attempt to intersect the informal networks that most street traders are implicated into. Markets such as the high-profile Metro Mall in the inner city of Johannesburg therefore serve as nodes of encounter between state and citizens, or what Law (2004) might refer to as Obligatory Points of Passage. Through these markets, the municipality has attempted to encourage traders to imagine themselves as responsible entrepreneurs, and to therefore implicate traders into new networks of association that allow traders to share in an imagination of the post-apartheid developmental state. However, these encounters do not always produce predictable outcomes, and I demonstrate how the Metro Mall serves also as a context for traders to represent to the municipality different expectations of citizenship.

Developing a Curriculum for Church Music Education: Balancing Theology and Musicianship

Subjects: Church Music Education, Musicianship.

description: Abstract: This study investigates the development of a comprehensive curriculum for church music education that harmonizes theological understanding with musical proficiency. Employing a mixed-methods approach, the research includes a literature review, surveys of existing church music programs, and interviews with church music educators. The aim is to identify essential components for a well-rounded curriculum that prepares students for effective ministry in worship settings. The results highlight four primary elements: theological studies, musical skills, liturgical knowledge, and practical leadership experience. The integration of these areas is crucial for fostering not only technical musical abilities but also the spiritual and communal dimensions of music within worship contexts. Additionally, the study emphasizes the need for church music education to go beyond performance, encouraging a deeper understanding of the role of music in spiritual formation and community-building. In conclusion, the findings suggest that a balanced church music curriculum must holistically address both musical and theological competencies to prepare future church musicians for leadership roles. This study contributes to ongoing discussions on enhancing church music education by providing insights into how educators can design curricula that nurture both the heart and skill of worship through music.

description: The purpose of the present work is a theoretical examination of how localized skin-tissue dehydration affects the depth of the confocal probing and what depth of effective detection can be reached with the chemical administration of skin tissues. A semi-infinite multilayer Monte Carlo model is used to estimate spatial localization of the output signal offered by a confocal probe. A solution of glycerol is taken in the capacity of innocuous osmotic agent. Diffusion of this bio-compatible chemical agent into the skin temporarily pushes water out of the tissues and results in the matching of the refractive indices of skin structural elements. This temporarily decreases scattering and increases transparency of topical skin layers, which allows for unrestricted light to permeate deeper into the skin. The results of simulation show that signal spatial localization offered by a confocal probe in the skin tissues during their clearing is usable for the monitoring of deep reticular dermis and improving the image contrast and spatial resolution. A discussion of the optical properties of skin tissues and their changes due to diffusion of glycerol into the skin is given. Optical properties of tissues and their changes due to chemical administration are estimated based on the results of experimental in vitro study with rat and human skin.

description: A search for new phenomena has been performed in final states with at least one isolated high-momentum photon, jets and missing transverse momentum in proton--proton collisions at a centre-of-mass energy of 13~TeV. The data, collected by the ATLAS experiment at the CERN LHC, correspond to an integrated luminosity of $139~\mathrm{fb}^{-1}$. The experimental results are interpreted in a supersymmetric model in which pair-produced gluinos decay into neutralinos, which in turn decay into a gravitino, at least one photon, and jets.No significant deviations from the predictions of the Standard Model are observed. Upper limits are set on the visible cross section due to physics beyond the Standard Model, and lower limits are set on the masses of the gluinos and neutralinos, all at 95\% confidence level.
