title: Neoliberal business as usual or paradigm shift? Planning under austerity localism
Creators: name: Dobson, Mark
Publisher: name: University of Reading
Year: 2019

description: This thesis presents an empírica/ qualitative analysis of the planning policy reforms and austerity measures enacted under the Cameron-led Coalition and majority Conservative Governments 2010-2016. The conceptual framework is developed by drawing on a neo/ibera/ structure-agency approach, with a specific focus on how externalised 'structural' planning neoliberalisations impact on local planning authority departments and planner's internalised 'agency' in England. The research is based on 40 semi-structured interviews with planning managers representing a diversity of rural-urban and regional contexts across England. The guiding rationale is that the particular scope, scale and temporal context of austerity, localism and planning reforms in England post-2010 represents more than a neo/ibera/ 'business as usual' approach, but rather forms a more fundamental set of post-crisis changes to the professional roles of public planners and objectives of the planning system more generally, in line with wider attempts at state restructuring during this period. The argument is made that the reallocation of responsibility and risk through such reforms has been key to the unfolding state restructuring in England post-2010, with planning further becoming both a punch bag for, but also agent of, neoliberalisations in England. However, that despite being conscripted into a stronger practice context of deregulation and austerity, the institutional positioning and professionalism and ethics of planners means that planning agency 'is in many respects the last fine of defence to space itself being neoliberalized' (Lord and Tewdwr-Jones, 2014, p. 357).
The seasonal and dirunal movements of some pacific salmon fry with particular reference to the sockeye, onchorynchus nerka
Creators: name: McDonald, John George
Publisher: name: University of British Columbia
Year: 2012

description: The seasonal and diurnal movements of sockeye, pink and coho salmon fry are described. For sockeye, at least, the time of the seasonal migration froa the spawning area is related to the temperature "budget" during their period of development in the gravel. Their seasonal migration occurs earlier following an incubatory period in which above average temperature prevailed and later following relatively low temperatures. Emergence from the gravel appears to occur normally only after a certain stage of development is reached. The diurnal movements of all three species are precisely regulated by their response to light. The strong negative phototaxis exhibited by the fry at this time restricts their movement solely to the hours of darkness. The downstream movement of sockeye and coho and also apparently of pink fry is initiated within a three hour period following darkness. The presence of artificial light almost completely prevents this movement either throughout the night or until such time as the light is removed. The data indicate that a period of night blindness occurs which is common to the three species and that their downstream movement is initially a result of a displacement by the current. Once entered into the stream the migration continues until evacuation of the stream is complete or until daylight approaches. The response of sockeye fry to current during this continued movement appears predominantly positive in fast currents and negative in relatively slew currents. The migration is considered to result from both a displacement by the current and a movement directed on the part of the fry.
Theory and design of quantum cascade lasers in (111) n-type Si/SiGe

description: Although most work toward the realization of group IV quantum cascade lasers (QCLs) has focused on valence-band transitions, there are many desirable properties associated with the conduction band. We show that the commonly cited shortcomings of n-type Si/SiGe heterostructures can be overcome by moving to the (111) growth direction. Specifically, a large band offset and low effective mass are achievable and subband degeneracy is preserved. We predict net gain up to lattice temperatures of 90 K in a bound-to-continuum QCL with a double-metal waveguide, and show that a Ge interdiffusion length of at least 8 angstroms across interfaces is tolerable.

description: Objective: To improve accelerated MRI reconstruction through a densely connected cascading deep learning reconstruction framework. Materials and Methods: A cascading deep learning reconstruction framework (baseline model) was modified by applying three architectural modifications: Input-level dense connections between cascade inputs and outputs, an improved deep learning sub-network, and long-range skip-connections between subsequent deep learning networks. An ablation study was performed, where five model configurations were trained on the NYU fastMRI neuro dataset with an end-to-end scheme conjunct on four- and eight-fold acceleration. The trained models were evaluated by comparing their respective structural similarity index measure (SSIM), normalized mean square error (NMSE) and peak signal to noise ratio (PSNR). Results: The proposed densely interconnected residual cascading network (DIRCN), utilizing all three suggested modifications, achieved a SSIM improvement of 8% and 11% for four- and eight-fold acceleration, respectively. For eight-fold acceleration, the model achieved a 23% decrease in the NMSE when compared to the baseline model. In an ablation study, the individual architectural modifications all contributed to this improvement, by reducing the SSIM and NMSE with approximately 3% and 5% for four-fold acceleration, respectively. Conclusion: The proposed architectural modifications allow for simple adjustments on an already existing cascading framework to further improve the resulting reconstructions.

description: We investigate quantum measurement strategies capable of discriminating two coherent states probabilistically with significantly smaller error probabilities than can be obtained using non- probabilistic state discrimination. We apply a postselection strategy to the measurement data of a homodyne detector as well as a photon number resolving detector in order to lower the error probability. We compare the two different receivers with an optimal intermediate measurement scheme where the error rate is minimized for a fixed rate of inconclusive results. The photon number resolving (PNR) receiver is experimentally demonstrated and compared to an experimental realization of a homodyne receiver with postselection. In the comparison it becomes clear, that the perfromance of the new PNR receiver surpasses the performance of the homodyne receiver, which we proof to be optimal within any Gaussian operations and conditional dynamics.

description: The magnetogenesis scenarios triggered by the early variation of the gauge coupling are critically analyzed. In the absence of sources, it is shown that the electric and magnetic power spectra can be explicitly computed by means of electric-magnetic duality transformations. The remnants of a pre-inflationary expansion and the reheating process break explicitly electric-magnetic duality by inducing Ohmic currents. The generation of large-scale magnetic field and the physical distinction between electric and magnetic observables stems, in this class of models, from the final value reached by the conductivity of the plasma right after inflation. Specific numerical examples are given. The physical requirements of viable magnetogenesis scenarios are spelled out.

Kondo "underscreening" cloud: spin-spin correlations around a partially screened magnetic impurity

description: We consider the spatial spin correlations around a partially screened spin-1 magnetic moment in a metal exhibiting the underscreened Kondo effect. We find that the underscreening of the impurity spin results in spatial spin correlations that are more pronounced as compared to the fully screened Kondo effect; their power-law decay is weaker because of characteristic logarithmic corrections at large distances. The spin correlator also changes sign as a function of distance to the impurity allowing for ferromagnetic correlations between conduction electron spin density and the local moment. The numerical findings are shown to be in agreement with the predictions deriving from an effective ferromagnetic Kondo Hamiltonian.

Reidemeister classes in some wreath products by $\mathbb Z^k$

description: Among restricted wreath products $G\wr \mathbb Z^k $, where $G$ is a finite Abelian group, we find three large classes of groups admitting an automorphism $φ$ with finite Reidemeister number $R(φ)$ (number of $φ$-twisted conjugacy classes). In other words, groups from these classes do not have the $R_\infty$ property. If a general automorphism $φ$ of $G\wr \mathbb Z^k$ has a finite order (this is the case for $φ$ detected in the first part of the paper) and $R(φ)<\infty$, we prove that $R(φ)$ coincides with the number of equivalence classes of finite-dimensional irreducible unitary representations of $G\wr \mathbb Z^k$, which are fixed by the dual map $[ρ]\mapsto [ρ\circ φ]$ (i.e. we prove the conjecture about finite twisted Burnside-Frobenius theorem, TBFT$_f$, for these $φ$).
Tailoring Structure-borne Sound Through Bandgap Engineering in Phononic Crystals and Metamaterials: A Comprehensive Review

description: In solid state physics, a bandgap (BG) refers to a range of energies where no electronic states can exist. This concept was extended to classical waves, spawning the entire fields of photonic and phononic crystals where BGs are frequency (or wavelength) intervals where wave propagation is prohibited. For elastic waves, BGs are found in periodically alternating mechanical properties (i.e., stiffness and density). This gives birth to phononic crystals and later elastic metamaterials that have enabled unprecedented functionalities for a wide range of applications. Planar metamaterials are built for vibration shielding, while a myriad of works focus on integrating phononic crystals in microsystems for filtering, waveguiding, and dynamical strain energy confinement in optomechanical systems. Furthermore, the past decade has witnessed the rise of topological insulators, which leads to the creation of elastodynamic analogs of topological insulators for robust manipulation of mechanical waves. Meanwhile, additive manufacturing has enabled the realization of 3D architected elastic metamaterials, which extends their functionalities. This review aims to comprehensively delineate the rich physical background and the state-of-the art in elastic metamaterials and phononic crystals that possess engineered BGs for different functionalities and applications, and to provide a roadmap for future directions of these manmade materials.

description: e study the properties of the mean-type mappings ${\bf M}\colon I^p \to I^p$ of the form $${\bf M}(x_1,\dots,x_p):=\big(M_1(x_{α_{1,1}},\dots,x_{α_{1,d_1}}),\dots,M_p(x_{α_{p,1}},\dots,x_{α_{p,d_p}})\big),$$ where $p$ and $d_i$-s are positive integers, each $M_i$ is a $d_i$-variable mean on an interval $I \subset \mathbb{R}$, and $α_{i,j}$-s are elements from $\{1,\dots,p\}$. We show that, under some natural assumption on $M_i$-s, the problem of existing the unique $\bf M$-invariant mean can be reduced to the ergodicity of the directed graph with vertexes $\{1,\dots,p\}$ and edges $\{(α_{i,j},i) \colon i,j \text{ admissible}\}$.

description: The Bin Packing Problem (BPP) stands out as a paradigmatic combinatorial optimization problem in logistics. Quantum and hybrid quantum-classical algorithms are expected to show an advantage over their classical counterparts in obtaining approximate solutions for optimization problems. We have recently proposed a hybrid approach to the one dimensional BPP in which a quantum annealing subroutine is employed to sample feasible solutions for single containers. From this reduced search space, a classical optimization subroutine can find the solution to the problem. With the aim of going a step further in the evaluation of our subroutine, in this paper we compare the performance of our procedure with other classical approaches. Concretely we test a random sampling and a random-walk-based heuristic. Employing a benchmark comprising 18 instances, we show that the quantum approach lacks the stagnation behaviour that slows down the classical algorithms. Based on this, we conclude that the quantum strategy can be employed jointly with the random walk to obtain a full sample of feasible solutions in fewer iterations. This work improves our intuition about the benefits of employing the scarce quantum resources to improve the results of a diminishingly efficient classical strategy.

description: We report on the transverse laser cooling of a magnetically guided beam of ultra cold chromium atoms. Radial compression by a tapering of the guide is employed to adiabatically heat the beam. Inside the tapered section heat is extracted from the atom beam by a two-dimensional optical molasses perpendicular to it, resulting in a significant increase of atomic phase space density. A magnetic offset field is applied to prevent optical pumping to untrapped states. Our results demonstrate that by a suitable choice of the magnetic offset field, the cooling beam intensity and detuning, atom losses and longitudinal heating can be avoided. Final temperatures below 65 microkelvin have been achieved, corresponding to an increase of phase space density in the guided beam by more than a factor of 30.

Creators: name: Guinot Saporta, José Vicente Guinot
Publisher: name: University of Reading
Year: 2019

description: The research presented here deals with the evolution of personality features of humans engaged in strategic interactions. The evolution of risk aversion and trustworthiness is modelled and simulated in the context of a binary trust game, seeking the origin and end-points of an evolutionary process, accounting for different degrees of locality. This research has employed computer simulations in order to get dynamic equilibria in populations of players that keep evolving. The locality or global nature of interaction plays an important role. Risk aversion evolves together with trust and trustworthiness. Trust behaviour follows reciprocation attributes. Results of the simulations are equal to the ones elicited in empirical studies.

description: We derive a Thermodynamic Uncertainty Relation bounding the mean squared displacement of a Gaussian process with memory, driven out of equilibrium by unbalanced thermal baths and/or by external forces. Our bound is tighter with respect to previous results and also holds at finite time. We apply our findings to experimental and numerical data for a many-body interacting granular fluid, characterized by regimes of anomalous diffusion. In some cases, our relation can distinguish between equilibrium and non-equilibrium behavior, a non-trivial inference task, particularly for Gaussian processes.

Relativistic calculation of the pion loop correlation energy in nuclear matter in a theory including confinement

description: We present a relativistic calculation of the saturation properties of nuclear matter which contains the correlation energy. Pion loops are incorporated on top of a relativistic Hartree-Fock (RHF) approach based on a chiral theory. It includes the effect of nucleon structure through its response to the background chiral invariant scalar field. All the parameters which enter the RHF calculation are fixed or strongly constrained by hadron phenomenology or lattice data. The new input for the correlation energy is the Landau-Migdal parameter g? governing the short-range part of the spin-isospin interaction. We find that the inclusion of the correlation energy improves the description of the saturation properties of nuclear matter.

description: The in-person Malta-based STEAM Summer School intensive science communication course was transformed into the STEAM Digital School due to COVID-19 pandemic restrictions. Still retaining real world features, the course managed to incorporate individuals from three different continents to learn and work together simultaneously. Upon completion of the course, the students organised an online event during worldwide stay-at-home restrictions to stimulate excitement among youth about scientific topics; in this case, communication within nature. The organisers developed an online treasure hunt for teenagers, a novel format for online learning. The game involved solving puzzles with a science theme through an online platform. Through this medium, the participants were exposed to scientific ideas such as quantum waves, and how a microwave works, in order to increase their possible interest in the area. The organisers aimed to encourage the participants to develop an interest in science and research within society, against the backdrop of the COVID-19 pandemic. The event was evaluated to assess the impact on the participants and organisers, and the results indicated the event was generally enjoyed by the participants, though some puzzle difficulties were perhaps too high for those in the targeted age bracket of 16 19-year-olds. Further suggestions for the improvement of the online intensive course and this event format are discussed within the report. We found the event format to be an overall success, with all participants indicating an increased interest in science as a result.
A high charge state Coronal Mass Ejection seen through solar wind charge exchange emission as detected by XMM-Newton

description: We present the analysis of an observation by XMM-Newton that exhibits strongly variable, low-energy diffuse X-ray line emission. We reason that this emission is due to localised solar wind charge exchange (SWCX), originating from a passing cloud of plasma associated with a Coronal Mass Ejection (CME) interacting with neutrals in the Earth's exosphere. This case of SWCX exhibits a much richer emission line spectrum in comparison with previous examples of geocoronal SWCX or in interplanetary space. We show that emission from OVIII is very prominent in the SWCX spectrum. The observed flux from oxygen ions of 18.9 keV cm-2 s-1 sr-1 is consistent with SWCX resulting from a passing CME. Highly ionised silicon is also observed in the spectrum, and the presence of highly charged iron is an additional spectral indicator that we are observing emission from a CME. We argue that this is the same event detected by the solar wind monitors ACE and Wind which measured an intense increase in the solar wind flux due to a CME that had been released from the Sun two days previous to the XMM-Newton observation.

description: In this work, we present an effective field theory for string inflation with spontaneously broken supersymmetry without generating any supersymmetric anti-de Sitter vacua. In that regard, we analyze the nilpotent superfields that effectively capture the physics of anti-D3 branes, and obtain the underlying pattern of universal attractors with a single parameter. Accordingly, we reveal a novel uplifting method by adding the same parameter as a complex contribution parallel to the decomposition of a superfield. Following that, we obtain an almost vanishing cosmological constant in a region where the inflationary attractors unify. Finally, we show that the introduction of nilpotent superfields drastically extends the string landscape for the de Sitter (swampland) conjecture, and the (super)universal attractors are in the string landscape in that respect.

description: In object tracking and state estimation problems, ambiguous evidence such as imprecise measurements and the absence of detections can contain valuable information and thus be leveraged to further refine the probabilistic belief state. In particular, knowledge of a sensor's bounded field-of-view can be exploited to incorporate evidence of where an object was not observed. This paper presents a systematic approach for incorporating knowledge of the field-of-view geometry and position and object inclusion/exclusion evidence into object state densities and random finite set multi-object cardinality distributions. The resulting state estimation problem is nonlinear and solved using a new Gaussian mixture approximation based on recursive component splitting. Based on this approximation, a novel Gaussian mixture Bernoulli filter for imprecise measurements is derived and demonstrated in a tracking problem using only natural language statements as inputs. This paper also considers the relationship between bounded fields-of-view and cardinality distributions for a representative selection of multi-object distributions, which can be used for sensor planning, as is demonstrated through a problem involving a multi-Bernoulli process with up to one-hundred potential objects.

Petrology of the Shingle Creek porphyry

Year: 2012

description: A brief description of the geology of the Shingle Creek area southwest of Penticton B.C. together with a more detailed report on the mineralogy and petrology of the Shingle Creek Intrusion (granite porphyry) are given. The presence of flows and tuffs showing similar mineralogical features to the Shingle Creek: Intrusion suggest that this intrusion was shallow rather than deep-seated. Sanidine phenocrysts showing oscillatory zoning are described with a range in composition of from 40 to 70 percent orthoclase (based on a comparison of optical properties with those determined by Tuttle 1952). The zones often occur in pairs showing a gradation from an albite-rich inner zone to an orthoclase-rich outer gone, It is tentatively suggested here that pressure changes in the magma, by altering the liquidus - solidus relations, sight provide this reversed- zoning. Plagioclase phenocrysts from the intrusion show transitional to high temperature optics when compared with the results of Bowen and Tuttle 1950. Beta quartz phenocrysts showing rounded outlines and development of late halos are described, from evidence given it is suggested that these features are due to resorption of quartz in a magma chamber prior to intrusion, followed by late growth after intrusion and daring crystallization of the porphyry matrix, Petrographlc study of the largest dyke associated with the porphyritic intrusion has suggested that this dyke may have been intruded in several stages.

Sono 700 i satelliti accatastati in maniera più o meno ordinata sull’orbita terrestre. Pochi rientrano alla base, come previsto, al termine della missione. I più continuano a vagare sopra le nostre teste, ormai fuori controllo. A oggi esiste un solo catalogo di questo complicato traffico atmosferico. Si chiama JSpOC ed è in mano alla Difesa statunitense. E l'Europa? Vota ad aprile un ambizioso programma di sorveglianza spaziale

A Bohr-Sommerfeld quantization formula for quasinormal frequencies of AdS black holes

description: We derive a quantization formula of Bohr-Sommerfeld type for computing quasinormal frequencies for scalar perturbations in an AdS black hole in the limit of large scalar mass or spatial momentum. We then apply the formula to find poles in retarded Green functions of boundary CFTs on $R^{1,d-1}$ and $RxS^{d-1}$. We find that when the boundary theory is perturbed by an operator of dimension $Δ>> 1$, the relaxation time back to equilibrium is given at zero momentum by ${1 \over ΔπT} << {1 \over πT}$. Turning on a large spatial momentum can significantly increase it. For a generic scalar operator in a CFT on $R^{1,d-1}$, there exists a sequence of poles near the lightcone whose imaginary part scales with momentum as $p^{-{d-2 \over d+2}}$ in the large momentum limit. For a CFT on a sphere $S^{d-1}$ we show that the theory possesses a large number of long-lived quasiparticles whose imaginary part is exponentially small in momentum.

description: Typical bodily and environmental fluids encountered by biological swimmers consist of dissolved macromolecules such as proteins and polymers, often rendering them non Newtonian. To mimic such scenarios, we investigate the motion of swimming droplets in an ambient medium doped with polymers as macromolecular solutes. Active droplets mimic the essential propulsive characteristics of several biological swimmers and serve as ideal model systems to widen our understanding of their locomotive strategies. Our experiments reveal extreme sensitivity of droplet motion to the presence of macromolecular solutes in the ambient medium. Through in-situ visualization of the self-generated chemical field around the droplet, we report unexpectedly high diffusivity of filled micelles in the presence of high molecular weight polymer solutes or macromolecules. This is attributed to the limitation of Stokes-Einstein relationship in accurately predicting micelle diffusivity due to significant size disparity between micelles and the macromolecular solute. With an increase in polymer concentration, particle image velocimetry reveals a mode-switching, from the conventional pusher mode to a puller mode of propulsion, characterized by a more persistent droplet motion. With a further increase in concentration, a secondary transition from smooth to a jittery mode of propulsion occurs. A robust Peclet number framework is proposed that successfully captures the observed mode-switching of active droplets. Our experiments unveil a novel route to orchestrate complex transitions in active droplet propulsion by doping the ambient medium with suitable choice of macromolecules.

Inelastic Production of J/psi Mesons in Photoproduction and Deep Inelastic Scattering at HERA

Year: 2010
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A measurement is presented of inelastic photo- and electroproduction of J/psi mesons in ep scattering at HERA. The data were recorded with the H1 detector in the period from 2004 to 2007. Single and double differential cross sections are determined and the helicity distributions of the J/psi mesons are analysed. The results are compared to theoretical predictions in the colour singlet model and in the framework of non-relativistic QCD. Calculations in the colour singlet model using a k_T factorisation ansatz are able to give a good description of the data, while colour singlet model calculations to next-to-leading order in collinear factorisation underestimate the data.
