description: Zero-macroscopic-strain deformation twinning (ZMS-DT) is widely observed in many face-centred-cubic (FCC) metals and alloys. However, the driving force of ZMS-DT is a controversial issue and has not been fully clarified for a long time. Based on molecular dynamics simulations to various FCC metals, we found that ZMS-DT, i.e. Σ3{112} incoherent twin boundary migration can be driven by simultaneously applying both normal and shear strains/stresses to the twin boundary (TB), and changing the sign of the normal or the shear strain/stress can change the direction of the incoherent TB migration. With analysing the results of atomistic strain energy calculation and anisotropic elasticity theory, we revealed the strain energy imbalance, which originates from elastic anisotropic response of materials, between the two sides of the twin boundary under normal–shear strain (or stress) coupling condition essentially drives the TB migration and twin growth. Eventually, we deduce that the elastic anisotropy ratio can be one of the key material constants which affect the twinnability of FCC metals.
Spin excitations in a monolayer scanned by a magnetic tip

description: Energy dissipation via spin excitations is investigated for a hard ferromagnetic tip scanning a soft magnetic monolayer. We use the classical Heisenberg model with Landau-Lifshitz-Gilbert (LLG)-dynamics including a stochastic field representing finite temperatures. The friction force depends linearly on the velocity (provided it is small enough) for all temperatures. For low temperatures, the corresponding friction coefficient is proportional to the phenomenological damping constant of the LLG equation. This dependence is lost at high temperatures, where the friction coefficient decreases exponentially. These findings can be explained by properties of the spin polarization cloud dragged along with the tip.

Strengths and Weaknesses of Parallel Tempering

description: Parallel tempering, also known as replica exchange Monte Carlo, is studied in the context of two simple free energy landscapes. The first is a double well potential defined by two macrostates separated by a barrier. The second is a `golf course' potential defined by microstates having two possible energies with exponentially more high energy states than low energy states. The equilibration time for replica exchange is analyzed for both systems. For the double well system, parallel tempering with a number of replicas that scales as the square root of the barrier height yields exponential speedup of the equilibration time. On the other hand, replica exchange yields only marginal speed-up for the golf course system. For the double well system, the free energy difference between the two wells has a large effect on the equilibration time. Nearly degenerate wells equilibrate much more slowly than strongly asymmetric wells. It is proposed that this difference in equilibration time may lead to a bias in measuring overlaps in spin glasses. These examples illustrate the strengths and weaknesses of replica exchange and may serve as a guide for understanding and improving the method in various applications.

Contributions of extended batch tests for assessing technical recyclability: A case study of low‐value battery flows

description: Good product recyclability is a prerequisite for the transition to a circular economy. However, today's product complexity and diversity in the urban mine result in heterogeneous and variable waste flows affecting process recycling efficiency (RE) and thus product recyclability. For batteries, waste flow composition and subsequent RE are determined by usage behavior, collection, and sorting into chemical battery subsystems. This study aims to demonstrate how extended batch tests (EBTs) can be used as a method to (a) determine battery-specific RE and (b) derive recommendations for assessing and improving the recyclability of batteries. Three EBTs comprising extensive characterization methods were carried out with mixtures of zinc-based (AZ) and lithium-based (LIB) batteries. The results showed that 0.20–0.27 kg/kg of the input mass was lost through flue gas and not recyclable. The metal fraction (0.15–0.19 kg/kg) was easily recyclable, while the mineral fractions of LIBs posed challenges for recycling and recovery (RR) due to the high elemental heterogeneity and pollutants originating from individual battery subsystems. In total, 0.79 kg/kg of AZs was recyclable, whereas 0.52 kg/kg of LIBs and 0.58 kg/kg of AZLIBs (a mixture of both) were recyclable after further treatment. In conclusion, the study demonstrated how the EBT approach can be used to extend recyclability assessment by providing waste flow characteristics for comparison with output quality requirements, enabling assignment of battery-specific RE and identification of poorly recyclable battery subsystems. Thus, the EBT approach can help improve and assess technical recyclability in the future.

description: We use magnetic force microscopy to both image and manipulate individual vortex lines threading single crystalline YBa$_2$Cu$_3$O$_{6.4}$, a layered superconductor. We find that when we pull the top of a pinned vortex, it may not tilt smoothly. Sometimes, we observe a vortex to break into discrete segments that can be described as short stacks of pancake vortices, similar to the "kinked" structure proposed by Benkraouda and Clem. Quantitative analysis gives an estimate of the pinning force and the coupling between the stacks. Our measurements highlight the discrete nature of stacks of pancake vortices in layered superconductors.

description: We discuss the equivalence between the categories of certain ribbon graphs and subgroups of the modular group $Γ$ and use it to construct exponentially large families of not Hurwitz equivalent simple braid monodromy factorizations of the same element. As an application, we also obtain exponentially large families of {\it topologically} distinct algebraic objects such as extremal elliptic surfaces, real trigonal curves, and real elliptic surfaces.
Quantum feedback by discrete quantum non-demolition measurements: towards on-demand generation of photon-number states

description: We propose a quantum feedback scheme for the preparation and protection of photon number states of light trapped in a high-Q microwave cavity. A quantum non-demolition measurement of the cavity field provides information on the photon number distribution. The feedback loop is closed by injecting into the cavity a coherent pulse adjusted to increase the probability of the target photon number. The efficiency and reliability of the closed-loop state stabilization is assessed by quantum Monte-Carlo simulations. We show that, in realistic experimental conditions, Fock states are efficiently produced and protected against decoherence.

A fuller flavour treatment of N_2-dominated leptogenesis

Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We discuss N_2-dominated leptogenesis in the presence of flavour dependent effects that have hitherto been neglected, in particular the off-diagonal entries of the flavour coupling matrix that connects the total flavour asymmetries, distributed in different particle species, to the lepton and Higgs doublet asymmetries. We derive analytical formulae for the final asymmetry including the flavour coupling at the N_2-decay stage as well as at the stage of washout by the lightest right-handed neutrino N_1. Moreover, we point out that in general part of the electron and muon asymmetries (phantom terms), can completely escape the wash-out at the production and a total B-L asymmetry can be generated by the lightest RH neutrino wash-out yielding so called phantom leptogenesis. However, the phantom terms are proportional to the initial N_2 abundance and in particular they vanish for initial zero N_2-abundance. Taking any of these new effects into account can significantly modify the final asymmetry produced by the decays of the next-to-lightest RH neutrinos, opening up new interesting possibilities for N_2-dominated thermal leptogenesis.

Two-component description of dynamical systems that can be approximated by solitons: The case of the ion acoustic wave equations of Plasma Physics

Year: 2008
Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)
subject: Pattern Formation and Solitons (nlin.PS)
subject: FOS: Physical sciences

description: A new approach to the perturbative analysis of dynamical systems, which can be described approximately by soliton solutions of integrable nonlinear wave equations, is employed in the case of small-amplitude solutions of the ion acoustic wave equations of Plasma Physics. Instead of the traditional derivation of a perturbed KdV equation, the ion velocity is written as a sum of two components: elastic and inelastic. In the single-soliton case, the elastic component is the full solution. In the multiple-soliton case, it is complemented by the inelastic component. The original system is transformed into two evolution equations: An asymptotically integrable Normal Form for ordinary KdV solitons, and an equation for the inelastic component. The zero-order term of the elastic component is a single- or multiple-soliton-solution of the Normal Form. The inelastic component asymptotes into a linear combination of single-soliton solutions of the Normal Form, with amplitudes determined by soliton interactions, plus a second-order decaying dispersive wave. Satisfaction of a conservation law by the inelastic component and of mass conservation by the disturbance to the ion density is determined solely by the initial data and/or boundary conditions imposed on the inelastic component. The electrostatic potential is a first-order quantity. It is affected by the inelastic component only in second-order. The charge density displays a triple-layer structure. The analysis is carried out through third order.

Effects due to a scalar coupling on the particle-antiparticle production in the Duffin-Kemmer-Petiau theory

description: The Duffin-Kemmer-Petiau formalism with vector and scalar potentials is used to point out a few misconceptions diffused in the literature. It is explicitly shown that the scalar coupling makes the DKP formalism not equivalent to the Klein-Gordon formalism or to the Proca formalism, and that the spin-1 sector of the DKP theory looks formally like the spin-0 sector. With proper boundary conditions, scattering of massive bosons in an arbitrary mixed vector-scalar square step potential is explored in a simple way and effects due to the scalar coupling on the particle-antiparticle production and localization of bosons are analyzed in some detail.

description: Non-functioning pituitary adenomas are frequently associated with recurrence after primary treatment despite their benign status. Patients frequently require multiple treatments including a combination of surgery and pituitary radiotherapy. These treatments, in addition to the tumour, increase the risk of hypopituitarism which is known to be associated with increased mortality. Currently there is a lack of consensus of reliable predictors of recurrence in patients with NFPA. Historically many tumours have not been immunohistochemically stained for pituitary hormones which has resulted in the tumour being erroneously labelled as a null cell tumour which has been reported to be at increased risk of recurrence. The development of reliable assays to perform staining on tumour samples for transcription factors has been suggested to reduce the frequency ofdiagnosis oftrue immunonegative tumours.
We performed a retrospective analysis of patients with surgically managed NFPA to assess whether the addition of transcription factor staining and markers of proliferation provides further information to aid in assessing risk of recurrence. We compared differences in outcomes between tumour sub-types. In addition to this we assessed outcomes in patients presenting with pituitary apoplexy. 
We demonstrated that the addition of transcription factors reclassified 62.9% of samples tested which had previously been labelled as null cell.The rate of recurrence in patients with immunonegative tumours significantly reduced when adding transcription factor staining to pituitary hormone staining. We have shown that tumours with SF-1 expression appear to behave differently dependent on expression of LH/FSH. Tumours which lack LH/FSH staining but which stain positively for SF-1 were more likely to require repeated intervention. 
Pituitary apoplexy is rare however it is predominantly a condition seen in patients with NFPA. We have shown that in selected patients conservative management can be used without deterioration in outcomes however there is a spectrum of clinical presentation. Long-term endocrine dysfunction and visual sequelae are common regardless of management type.

Publisher: name: University of Kent

description: In this thesis we bring a series of contributions to the topic of multivariate asset modelling with dependence. In the first part of the thesis (chapters 2, 3 and 4) we look at equity modelling by factor models obtained by multivariate subordination of Lévy basis and discuss multi-asset derivative pricing by Fourier transform methods. More specifically, in the second chapter we propose a construction method for obtaining factor models based on multivariate subordination which extends the results of Barndorff-Nielsen et al. (2001). A lemma describing the characteristic function for the entire class of models is provided which opens the gates for multi-asset derivative pricing by Fourier transform methods under this class of models. Classification, parametrisation and the dependence structure details for the models in this class are then discussed in the second part of the chapter. The chapters 3 and 4 propose each a different three-factor model for the evolution of equity returns and provide the details of martingale asset pricing, calibration and multi-asset derivative pricing methods under the specific model. The specific applications that are treated are the spread options, in chapter 3 and CVA evaluation for forward contracts, in chapter 4. In the second part of the thesis (chapter 5) we look at the multi-name credit modelling in the context of factor models built by time-changes. Specifically, we propose a factor extension of the univariate default model proposed in Packham et al. (2013)and then we discuss the calibration and the pricing methodology (including details of their implementation) for single-name and multi-name credit derivatives contracts. The specific applications that are treated are the pricing and calibration on Credit Default Swaps, Credit Index Default Swaps and Index Tranches (synthetic CDOs).

description: Entanglement of spins is analyzed for two electrons extracted from a mixed many electron state by projecting onto the two-electron subspace. The concurrence formulae are expressed in a compact form for states with a well defined square of the total spin projection. As an example, the thermal entanglement for a qubit pair with an anisotropic Heisenberg and the Dzyaloshinskii-Moriya interactions in an inhomogeneous magnetic field is given analytically. Remarkably, the concurrence of a pair of electrons with antiparallel spins and in a delocalised orbital state is given by the scalar product of the state with its spin-flipped state and not with the time-reversed state.

We present the world's most precise measurements of the chi_{cJ,(J=0,2)} -> pi^+pi^-, pi^0 pi^0, K^+K^-, K^0_S K^0_S, eta eta and eta^{prime} eta^{prime} branching fractions, and a search for chi_c decays into eta eta^{prime}.

Desingularisation of orbifolds obtained from symplectic reduction at generic coadjoint orbits

description: We show how to construct a resolution of symplectic orbifolds obtained as quotients of presymplectic manifolds with a torus action. As a corollary, this allows us to desingularise generic symplectic quotients. Given a manifold with a Hamiltonian action of a compact Lie group, symplectic reduction at a coadjoint orbit which is transverse to the moment map produces a symplectic orbifold. If moreover the points of this coadjoint orbit are regular elements of the Lie coalgebra, that is, their stabiliser is a maximal torus, the result for torus quotients may be applied to obtain a desingularisation of these symplectic orbifolds. Regular elements of the Lie coalgebra are generic in the sense that the singular strata have codimension at least three. Additionally, we show that even though the result of a symplectic cut is an orbifold, it can be modified in an arbitrarily small neighbourhood of the cut hypersurface to obtain a smooth symplectic manifold.

description: Three types of first generation epitaxial graphene field effect transistors (FET) are presented and their relative merits are discussed. Graphene is epitaxially grown on both the carbon and silicon faces of hexagonal silicon carbide and patterned with electron beam lithography. The channels have a Hall bar geometry to facilitate magnetoresistance measurements. FETs patterned on the Si-face exhibit off-to-on channel resistance ratios that exceed 30. C-face FETs have lower off-to-on resistance ratios, but their mobilities (up to 5000 cm2/Vs) are much larger than that for Si-face transistors. Initial investigations into all-graphene side gate FET structures are promising.
Causal Inference on Discrete Data using Additive Noise Models

description: Inferring the causal structure of a set of random variables from a finite sample of the joint distribution is an important problem in science. Recently, methods using additive noise models have been suggested to approach the case of continuous variables. In many situations, however, the variables of interest are discrete or even have only finitely many states. In this work we extend the notion of additive noise models to these cases. We prove that whenever the joint distribution $\prob^{(X,Y)}$ admits such a model in one direction, e.g. $Y=f(X)+N, N \independent X$, it does not admit the reversed model $X=g(Y)+\tilde N, \tilde N \independent Y$ as long as the model is chosen in a generic way. Based on these deliberations we propose an efficient new algorithm that is able to distinguish between cause and effect for a finite sample of discrete variables. In an extensive experimental study we show that this algorithm works both on synthetic and real data sets.
Magnetic anomalies in Nd6Co(1.67)Si3: Surprising first order transitions in the low-temperature isothermal magnetization

description: We present the results of magnetic measurements on Nd6Co(1.67)Si3, a compound recently reported to crystallize in a hexagonal structure (space group P6_3/m) and to undergo long range magnetic ordering below 84 K. The results reveal that the magnetism of this compound is quite complex with additional magnetic anomalies near 50 and 20 K. There are qualitative changes in the isothermal magnetization behavior with the variation of temperature. Notably, there is a field-induced spin reorientation as the temperature is lowered below 20 K. A finding we stress is that this transition is discontinuous for 1.8K in the virgin curve, but the first order character appears only after a field-cycling for a narrow higher temperature range near 5 K. Thus, this compound serves as an example for the stabilisation of first-order transition induced by magnetic-field-cycling. The issues of 'Phase co-existence' and 'meta-stability' after a field-cycling at low temperatures in this compound are also addressed.
