description: Given the extreme precision attainable with the Kepler Space Telescope, the mitigation of instrumental artefacts is very important. In an earlier paper (Murphy 2012), the characteristics of Kepler data were discussed in light of their effect on asteroseismology. We continue this discussion now that data processed with the new PDC-MAP pipeline are publicly available; users should use the latest data reductions available at the Mikulski Archive for Space Telescopes (MAST), not just for PDC, but also for improvements in the attached meta-data. We discuss the injection of noise in the frequency range 0-24 c/d (up to ~277 μHz) by the PDC-LS pipeline into ~15 per cent of light-curves.

How do psychological therapy practitioners, in their therapeutic approach, understand and work towards the empowerment of women who have been victims of violence?

description: Violence against women and women’s oppression are reciprocally related – just as oppressive patriarchal contexts are conducive to violence, violence is also a tool for subjugating women. Women’s empowerment is therefore often cited as a goal for psychological therapies provided to women who have been subjected to violence. However, literature surrounding empowerment within therapy holds various contradictions, gaps and problematic implications for women. Little is known about how UK practitioners navigate these issues. This research explored how practitioners conceptualise and approach empowerment within their therapeutic work with women subjected to violence. Semi-structured interviews were conducted with 12 psychological therapy practitioners representing a range of modalities, experienced in working with women subjected to violence. A reflexive thematic analysis, through a critical realist and feminist lens, was used to analyse participants’ reports. Three overarching themes were constructed: understanding empowerment, ‘what I do with clients’, and ‘a hand tied behind our back’: practitioners face barriers to empowering therapeutic practice. Participants predominantly aligned with an individualistic approach to empowerment centred around connection, coping, and reparation; and highlighted systemic barriers to ideal practice. Implications, limitations and suggested further research are discussed.
The low energy dynamics of charge two dyonic instantons

description: We explore the low energy dynamics of charge two instantons and dyonic instantons in SU(2) 5-dimensional Yang-Mills. We make use of the moduli space approximation and first calculate the moduli space metric for two instantons. For dyonic instantons the effective action of the moduli space approximation also includes a potential term which we calculate. Using the ADHM construction we are able to understand some aspects of the topology and structure of the moduli space. We find that instantons undergo right angled scattering after a head on collision and we are able to give an analytic description of this in terms of a quotient of the moduli space by symmetries of the ADHM data. We also explore the scattering of instantons and dyonic instantons numerically in a constrained region of the moduli space. Finally we exhibit some examples of closed geodesics on the moduli space, and geodesics which hit the moduli space singularities in finite time.

description: Although consumers are increasingly willing to pay for the environment, the private provision of public goods from the consumption of green goods remains limited. We propose in this paper to exploit an additional private attribute of green goods, the health benefits, in order to increase the provision of public good. Health can be seen as a positive internality associated with the consumption of some green goods. We show that correcting this internality by offering labels describing these health benefits can increase the supply of public goods. The level of public good remains underprovided from the perspective of a social planner, but, under certain conditions, may equalize or exceed the optimal level of the public good from the perspective of an environmental agency. A simulation is performed to illustrate the impact of consumer preferences on the provisioning of public good at market equilibrium.

description: Excerpts from the report: In the United States and in several other countries experiments have been conducted for many years to reduce decay of peaches from the time they are picked until they are consumed. Most decay control operations include removing field heat from the peaches as quickly as possible followed by holding or shipping the fruit at low temperatures. Hydrocooling the fruit immediately after harvest is an extremely effective way of removing field heat. However, neither hydrocooling nor short transit periods at low temperatures reduce decay of peaches during the subsequent ripening period at more moderate temperatures. It is during this period that chemicals may be useful to reduce decay. Peaches were obtained from wholesale houses in Washington, D.C., or nearby orchards. Information is given on (a) effect of water temperature and length of exposure on decay development; (b) effect of holding at 50° or 32° F. and of hydrocooling on heated peaches; (c) peach temperatures during heating and hydrocooling; (d) decay of peaches at 70° F. as affected by hot water or hot air treatments; (e) effect of hot water on decay-producing organisms; (f) the effect of hot water on decay of peaches and nectarines packaged in open and overwrapped consumer-size units.

description: We present the systematic study of the resonant tunneling spectroscopy on a series of ferromagnetic-semiconductor Ga1-xMnxAs with the Mn content x from ~0.01 to 3.2%. The Fermi level of Ga1-xMnxAs exists in the band gap in the whole x region. The Fermi level is closest to the valence band (VB) at x=1.0% corresponding to the onset of ferromagnetism near the metal-insulator transition (MIT), but it moves away from the VB as x increasing or decreasing from 1.0%. This anomalous behavior of the Fermi level indicates that the ferromagnetism and MIT emerge in the Mn-derived impurity band.

description: The shutdown of star formation in galaxies is generally termed `quenching'. Although quenching may occur through a variety of processes, the exact mechanism(s) that is in fact responsible for quenching is still in question. This paper addresses quenching by searching for traces of possible quenching processes through their effects on galaxy structural parameters such as surface stellar mass density and Sersic index (n). We analyze the rest-frame U-B color correlations versus these structural parameters using a sample of galaxies in the redshift range 0.5< z<0.8 from the DEEP2/AEGIS survey. We find that Sersic index (n) has the smallest overlap region among all tested parameters and resembles a step-function with a threshold value of n=2.3. There exists, however, a significant population of outliers with blue colors yet high n values that seem to contradict this behavior. We hypothesize that their Sersic values may be distorted by bursts of star formation, AGNs, and/or poor fits, leading us to consider central surface stellar mass density as an alternative to Sersic index. Not only does it correct the outliers, it also forms a tight relationship with color, suggesting that the innermost structure of galaxies is most physically linked with quenching. Furthermore, at z~0.65, the majority of the blue cloud galaxies cannot simply fade onto the red sequence since their GIM2D bulge masses are only half as large on average as the bulge masses of similar red sequence galaxies, thus demonstrating that stellar mass must absolutely increase at the centers of galaxies as they quench. We discuss a two-stage model for quenching in which galaxy star formation rates are controlled by their dark halos while they are still in the blue cloud and a second quenching process sets in later, associated with the central stellar mass build-up.

description: Nanomaterials exhibit many unique properties compared to traditional bulk materials, interfaces play a more important role in nanoscale systems by significantly influencing the mechanical performance. In this thesis, we focus on an intricate exploration of various interfaces, ranging from simple GBs in bicrystal models to intricate GB networks within polycrystalline structures and interfaces within nanocomposite materials. Various computational methodologies, including MD, DFT, and advanced machine learning algorithms, were employed to simulate and predict the mechanical properties of interfaces with microstructural complexity.Firstly, utilizing MC/MD simulations, we established a distinct correlation between GB motion in the Cantor alloy and the Cr concentration within the GBs. A formulation is calculated to link the GB mobility with the Cr concentration. Subsequently, DFT simulations highlight that vacancies in Tungsten GBs prefer to appear in the layer adjacent to the GB plane rather than the GB plane itself. These vacancies, as the findings suggest, cause the strength to decrease under tensile loading. Then, to expedite the prediction of interfacial properties, a cGAN model was developed to predict GB network evolution in polycrystalline samples based on the training data of MD simulation results. Finally, two modified deep learning models are introduced including the CNN-Prob and FNN-Prob, to predict the yield stress of a composite material, Cu-Cu/Zr. These models encompassed dual components for predicting both mean values and associated standard deviations.

description: The primary objective of endodontic therapy is to achieve a three-dimensional obturation of the root canal space to remove the tissue debris, microorganisms and their by products after a proper biomechanical preparation of the pulp chambers. The missing canal of complex root canal morphology is major reason for endodontic failure. The use of magnification, illumination, recent advancements, diagnostic aids and techniques help in minimizing the incidence of missing a canal. This case report describes the rare management of a left mandibular first permanent molar requiring root canal treatment with an additional Middle Mesial Canal (MMC) in the mesial root. Clinicians experience and approach is a key factor in negotiation and management of these aberrant canal configurations. After a proper access cavity preparation, clinicians should spend time in examining the mesial sub pulpal groove to detect and negotiate additional canal.

description: The time-dependent matrix-product-state (TDMPS) simulation method has been used for numerically simulating quantum computing for a decade. We introduce our C++ library ZKCM_QC developed for multiprecision TDMPS simulations of quantum circuits. Besides its practical usability, the library is useful for evaluation of the method itself. With the library, we can capture two types of numerical errors in the TDMPS simulations: one due to rounding errors caused by the shortage in mantissa portions of floating-point numbers; the other due to truncations of nonnegligible Schmidt coefficients and their corresponding Schmidt vectors. We numerically analyze these errors in TDMPS simulations of quantum computing.

description: There often appear coherently oscillating scalar fields in particle physics motivated cosmological scenarios, which may have rich phenomenological consequences. Scalar fields should somehow interact with background thermal bath in order to decay into radiation at an appropriate epoch, but introducing some couplings to the scalar field makes the dynamics complicated. We investigate in detail the dynamics of a coherently oscillating scalar field, which has renormalizable couplings to another field interacting with thermal background. The scalar field dynamics and its resultant abundance are significantly modified by taking account of following effects : (1) thermal correction to the effective potential, (2) dissipation effect on the scalar field in thermal bath, (3) non-perturbative particle production events and (4) formation of non-topological solitons. There appear many time scales depending on the scalar mass, amplitude, couplings and the background temperature, which make the efficiencies of these effects non-trivial.

title: Essays on the economics of conflict
Creators: name: Hönig, Tillman
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2021

description: This thesis explores the economic consequences of violent conflict in two African countries: Sierra Leone and Nigeria. The first chapter establishes that civil war in Sierra Leone has important local economic effects. Almost twenty years after the end of the war, greater conflict intensity in a chiefdom leads to a higher share of agricultural workers, fewer educated workers and lower income. In order to explicitly account for general equilibrium effects such as selective migration in response to the war, the second chapter develops an economic geography model. The model sheds light on different mechanisms through which conflict affects aggregate income: Changes in education, firm productivity and individual productivity have both direct effects on income and indirect effects by changing the allocation of labor across sectors and locations. Changes in amenities also affect the spatial allocation of labor. I leverage the structure of the model along with observed income information and migration flows to identify firm productivities, amenities and average individual productivities. The model is used to perform counterfactual simulations. Aggregate income in Sierra Leone is estimated to be 32% lower today as a result of the civil war. Importantly, despite having received little attention in conflict research so far, firm productivity losses can explain most of the decrease. Selective migration in response to the war also seems to play an important role and implies that local reduced-form effects are misleading when trying to estimate aggregate effects. The third chapter exploits a peace policy that the Nigerian government implemented in the Niger Delta region in 2009 to evaluate the effects of conflict reduction. I construct a synthetic control region from the states that are not part of the Niger Delta region and therefore unaffected by the policy as a withincountry counterfactual to the Niger Delta region. I find that peace following the policy increased household expenditures by 19% four years later. Uncovering potential mechanisms behind this economic upturn, I find an increase in selfemployment income by 67% and in education by 0.5 years of schooling. In line with the findings from Sierra Leone, these results highlight the important link between conflict and business activity.

description: The paper surveys some recent results concerning vector analysis on fractals. We start with a local regular Dirichlet form and use the framework of 1-forms and derivations introduced by Cipriani and Sauvageot to set up some elements of a related vector analysis in weak and non-local formulation. This allows to study various scalar and vector valued linear and non-linear partial differential equations on fractals that had not been accessible before. Subsequently a stronger (localized, pointwise or fiberwise) version of this vector analysis can be developed, which is related to previous work of Kusuoka, Kigami, Eberle, Strichartz, Hino, Ionescu, Rogers, Röckner, and the authors.

description: Alkaline-earth-metal atoms exhibit long-range dipolar interactions, which are generated via the coherent exchange of photons on the 3P_0-3D_1-transition of the triplet manifold. In case of bosonic strontium, which we discuss here, this transition has a wavelength of 2.7 μm and a dipole moment of 2.46 Debye, and there exists a magic wavelength permitting the creation of optical lattices that are identical for the states 3P_0 and 3D_1. This interaction enables the realization and study of mixtures of hard-core lattice bosons featuring long-range hopping, with tuneable disorder and anisotropy. We derive the many-body Master equation, investigate the dynamics of excitation transport and analyze spectroscopic signatures stemming from coherent long-range interactions and collective dissipation. Our results show that lattice gases of alkaline-earth-metal atoms permit the creation of long-lived collective atomic states and constitute a simple and versatile platform for the exploration of many-body systems with long-range interactions. As such, they represent an alternative to current related efforts employing Rydberg gases, atoms with large magnetic moment, or polar molecules.

description: Excerpts from the report: Postharvest rots of peaches and nectarines have been reduced with fungicidal dips and with fungicide-impregnated waxes or wraps. Hot-water treatments also have effectively reduced decay of eastern-grown varieties of peach and nectarine. Further work, summarized in this report, has been necessary to evaluate the performance of heat treatments under actual commercial conditions, and in combination with other fungicides. In addition, evaluations were needed of other methods of heat-treating fruit, such as moisture-saturated air or hot-flood showers. The performance of commercial heat treatments for peaches and nectarines also needed to be compared with fungicide-impregnated wax emulsions, which are used in some sheds.

description: We study 4D F-theory compactifications on singular Calabi-Yau fourfolds with fluxes. The resulting N=1 effective theories can admit non-Abelian and U(1) gauge groups as well as charged chiral matter. In these setups we analyze anomaly cancellation and the generalized Green-Schwarz mechanism. This requires the study of 3D N=2 theories obtained by a circle compactification and their M-theory duals. Reducing M-theory on resolved Calabi-Yau fourfolds corresponds to considering the effective theory on the 3D Coulomb branch in which certain massive states are integrated out. Both 4D gaugings and 3D one-loop corrections of these massive states induce Chern-Simons terms. All 4D anomalies are captured by the one-loop terms. The ones corresponding to the mixed gauge-gravitational anomalies depend on the Kaluza-Klein vector and are induced by integrating out Kaluza-Klein modes of the U(1) charged matter. In M-theory all Chern-Simons terms classically arise from G_4-flux. We find that F-theory fluxes implement automatically the 4D Green-Schwarz mechanism if non-trivial geometric relations for the resolved Calabi-Yau fourfold are satisfied. We confirm these relations in various explicit examples and elucidate the general construction of U(1) symmetries in F-theory. We also compare anomaly cancellation in F-theory with its analog in Type IIB orientifold setups.

description: We present an analysis of normal and inverted hierarchical neutrino mass models within the framework of tri-bi-maximal (TBM) mixing. Considering the neutrinos to be quasi-degenerate (QDN), we study two different neutrino mass models with mass eigenvalues $(m_1, -m_2, m_3)$ and $(m_1, m_2, m_3)$ for both normal hierarchical (NH) and inverted hierarchical (IH) cases. Parameterizing the neutrino mass matrix using best fit oscillation and cosmology data for a QDN scenario, we find the right-handed Majorana mass matrix using type I seesaw formula for two types of Dirac neutrino mass matrices: charged lepton (CL) type and up quark (UQ) type. Incorporating the presence of type II seesaw term which arises naturally in generic left-right symmetric models (LRSM) along with type I term, we compare the predictions for neutrino mass parameters with the experimental values. Within such a framework and incorporating both oscillation as well as cosmology data, we show that QDN scenario of neutrino masses can still survive in nature with some minor exceptions. A viable extension of the standard model with an abelian gauged flavor symmetry is briefly discussed which can give rise to the desired structure of the Dirac and Majorana mass matrices.

Iatrogenic Harm

description: Background: Research has shown that Dialectical Behaviour Therapy (DBT) is effective in reducing self-harm and suicidal ideation. However, research regarding experiences of DBT, particularly those of a negative nature, is sparse. The limited findings suggest that clients have reported difficulties in the therapeutic relationship, and staff have observed DBT to overly rigid, and constrained by organisational factors. However, no research has focused on both groups’ understandings of negative effects. Aims: To explore client and staff experiences of the negative effects from DBT and investigate how their understandings compare. In addition, to explore how staff address any negative effects that arise. Methodology: Underpinned by critical realism, this research adopted a qualitative approach. Eight client participants and seven staff participants, who had experienced or witnessed negative experiences from DBT, engaged in semistructured interviews, the transcripts of which were analysed using reflexive thematic analysis. Analysis: Four themes relating to client experiences were generated: “I’m the problem”, “DBT can do no wrong”, “No understanding of trauma”, and ‘An unhealthy “blueprint for relationships”’. Five themes relating to staff experiences were generated: “It’s not me, it’s the client”, ‘DBT or nothing’, “We don’t do ‘why’ in DBT”, “We did make some changes”, and ‘Organisational “restrictions”’. Conclusion: Both staff and clients understood negative effects from DBT to include pathologization and re-traumatisation. However, whilst clients related negative effects to the therapeutic relationship, staff highlighted the impact of organisational restrictions. Given the study design and selection bias, this study cannot ascertain the prevalence of negative effects from DBT. Nonetheless, the findings support recommendations for practice, including adapting DBT to become trauma-informed, and prioritising informed consent.

It depicts parental alienation in the context of a high-conflict divorce, which could be overcome with a concerted intervention by child protective services and the family court, in collaboration with a trained psychologist. Despite the existence of over a thousand professional articles, book chapters, and books, as well as empirical research from all over the world (see website https://ckm.vumc.org/pasg), there is still a lack of awareness or even denial of parental alienation in professional practise. Stopping parental alienating behaviours is imperative for the promotion of the best interests of children and the health of families.

description: An explicit form of the magnetic moment tensor operator for non-Dirac particles with rest spin 1/2 and its essential difference from the spin operator are established. Possible consequences of the last fact for the description of the spin rotation in the magnetic field and for the values of magnetic moments of some nuclei, as well as the impact of this and other facts on the validity of modelling the azimuthal asymmetry of the secondary-scattered protons in $ep$-experiments are noted.

description: In this paper we define (local) Dirac operators and magnetic Schrödinger Hamiltonians on fractals and prove their (essential) self-adjointness. To do so we use the concept of 1-forms and derivations associated with Dirichlet forms as introduced by Cipriani and Sauvageot, and further studied by the authors jointly with Röckner, Ionescu and Rogers. For simplicity our definitions and results are formulated for the Sierpinski gasket with its standard self-similar energy form. We point out how they may be generalized to other spaces, such as the classical Sierpinski carpet.

description: A biclique of a graph G is an induced complete bipartite graph. A star of G is a biclique contained in the closed neighborhood of a vertex. A star (biclique) k-coloring of G is a k-coloring of G that contains no monochromatic maximal stars (bicliques). Similarly, for a list assignment L of G, a star (biclique) L-coloring is an L-coloring of G in which no maximal star (biclique) is monochromatic. If G admits a star (biclique) L-coloring for every k-list assignment L, then G is said to be star (biclique) k-choosable. In this article we study the computational complexity of the star and biclique coloring and choosability problems. Specifically, we prove that the star (biclique) k-coloring and k-choosability problems are Σ_2^p-complete and Π_3^p-complete for k > 2, respectively, even when the input graph contains no induced C_4 or K_{k+2}. Then, we study all these problems in some related classes of graphs, including H-free graphs for every H on three vertices, graphs with restricted diamonds, split graphs, threshold graphs, and net-free block graphs.

description: A Mathematica package for color summed calculations in QCD (SU(Nc)) is presented. Color contractions of any color amplitude appearing in QCD may be performed, and the package uses a syntax which is very similar to how color structure is written on paper. It also supports the definition of color vectors and bases, and special functions such as scalar products are defined for such color tensors.

description: Pair production in a constant electric field is closely analogous to bubble nucleation in a false vacuum. The classical trajectories of the pairs are Lorentz invariant, but it appears that this invariance should be broken by the nucleation process. Here, we use a model detector, consisting of other particles interacting with the pairs, to investigate how pair production is seen by different Lorentzian observers. We focus on the idealized situation where a constant external electric field is present for an infinitely long time, and we consider the in-vacuum state for a charged scalar field that describes the nucleating pairs. The in-vacuum is defined in terms of modes which are positive frequency in the remote past. Even though the construction uses a particular reference frame and a gauge where the vector potential is time dependent, we show explicitly that the resulting quantum state is Lorentz invariant. We then introduce a "detector" particle which interacts with the nucleated pairs, and show that all Lorentzian observers will see the particles and antiparticles nucleating preferentially at rest in the detector's rest frame. Similar conclusions are expected to apply to bubble nucleation in a sufficiently long lived vacuum. We also comment on certain unphysical aspects of the Lorentz invariant in-vacuum, associated with the fact that it contains an infinite density of particles. This can be easily remedied by considering Lorentz breaking initial conditions.

Subbarrier fusion reactions and many-particle quantum tunneling

description: Low energy heavy-ion fusion reactions are governed by quantum tunneling through the Coulomb barrier formed by a strong cancellation of the repulsive Coulomb force with the attractive nuclear interaction between the colliding nuclei. Extensive experimental as well as theoretical studies have revealed that fusion reactions are strongly influenced by couplings of the relative motion of the colliding nuclei to several nuclear intrinsic motions. Heavy-ion subbarrier fusion reactions thus provide a good opportunity to address a general problem on quantum tunneling in the presence of couplings, which has been a popular subject in the past decades in many branches of physics and chemistry. Here we review theoretical aspects of heavy-ion subbarrier fusion reactions from the view point of quantum tunneling in systems with many degrees of freedom. Particular emphases are put on the coupled-channels approach to fusion reactions, and the barrier distribution representation for multi-channel penetrability. We also discuss an application of the barrier distribution method to elucidation of the mechanism of dissociative adsorption of H$_2$ melecules in surface science.

description: We study the semilinear wave equation \[ \partial_t^2 ψ-Δψ=|ψ|^{p-1}ψ\] for $p > 3$ with radial data in three spatial dimensions. There exists an explicit solution which blows up at $t=T>0$ given by \[ ψ^T(t,x)=c_p (T-t)^{-\frac{2}{p-1}} \] where $c_p$ is a suitable constant. We prove that the blow up described by $ψ^T$ is stable in the sense that there exists an open set (in a topology strictly stronger than the energy) of radial initial data that lead to a solution which converges to $ψ^T$ as $t\to T-$ in the backward lightcone of the blow up point $(t,r)=(T,0)$.

description: We propose a new measure to characterize the dimension of complex networks based on the ergodic theory of dynamical systems. This measure is derived from the correlation sum of a trajectory generated by a random walker navigating the network, and extends the classical Grassberger-Procaccia algorithm to the context of complex networks. The method is validated with reliable results for both synthetic networks and real-world networks such as the world air-transportation network or urban networks, and provides a computationally fast way for estimating the dimensionality of networks which only relies on the local information provided by the walkers.
