description: We calculate the leading contributions to the connected two-point functions of protected scalar operators in the defect version of N=4 SYM theory which is dual to the D5-D3 probe-brane system with k units of background gauge field flux. This involves several types of two-point functions which are vanishing in the theory without the defect, such as two-point functions of operators of unequal conformal dimension. We furthermore exploit the operator product expansion (OPE) and the boundary operator expansion (BOE), which form the basis of the boundary conformal bootstrap equations, to extract conformal data both about the defect CFT and about N=4 SYM theory without the defect. From the knowledge of the one- and two-point functions of the defect theory, we extract certain structure constants of N=4 SYM theory using the (bulk) OPE and constrain certain bulk-bulk-to-boundary couplings using the BOE. The extraction of the former relies on a non-trivial, polynomial k dependence of the one-point functions, which we explicitly demonstrate. In addition, it requires the knowledge of the one-point functions of SU$(2)$ descendant operators, which we likewise explicitly determine.

description: This thesis details the development of a new computational tool for simulating gas flows around black holes. Using this tool, it investigates the shredding of stars by supermassive black holes due to extreme tidal forces and the subsequent light that is emitted. It confirms a model that has been proposed to explain puzzling properties of optical and ultra-violet emission in such events, which have been observed at the centres of galaxies.
Motor-to-auditory correspondence and adaptation (Chao & Daliri, 2023)

description: Purpose: When the speech motor system encounters errors, it generates adaptive responses to compensate for the errors. Unlike errors induced by formant-shift perturbations, errors induced by formant-clamp perturbations do not correspond with the speaker’s speech (i.e., degraded motor-to-auditory correspondence). We previously showed that adaptive responses to formant-clamp perturbations are smaller than responses to formant-shift perturbations when perturbations are introduced gradually. This study examined responses to formant-clamp and formant-shift perturbations when perturbations are introduced suddenly.Method: One group of participants (n = 30) experienced gradually introduced formant-clamp and formant-shift perturbations, and another group (n = 30) experienced suddenly introduced formant-clamp and formant-shift perturbations. We designed the perturbations based on participant-specific vowel configurations such that a participant’s first and second formants of /ɛ/ were perturbed toward their /æ/. To estimate adaptive responses, we measured formant changes (0–100 ms of the vowel) in response to the formant perturbations.Results: We found that (a) the difference between responses to formant-clamp and formant-shift perturbations was smaller when the perturbations were introduced suddenly and (b) responses to suddenly introduced (but not gradually introduced) formant-shift perturbations positively correlated with responses to formant-clamp perturbations.Conclusions: These results showed that the speech motor system responds to errors induced by formant-shift and formant-clamp perturbations more differently when perturbations are introduced gradually than suddenly. Overall, the quality of errors (formant-shift vs. formant-clamp) and the manner of introducing errors (gradually vs. suddenly) modulate the speech motor system’s evaluations of and responses to errors.Supplemental Material S1.

A Generalized Ising Model for studying Alloy Evolution under Irradiation and its use in Kinetic Monte Carlo Simulations

Year: 2016
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We derive an Ising Hamiltonian for kinetic simulations involving interstitial and vacancy defects in binary alloys. Our model, which we term `ABVI', incorporates solute transport by both interstitial defects and vacancies into a mathematically-consistent framework , and thus represents a generalization to the widely-used ABV model for alloy evolution simulations. The Hamiltonian captures the three possible interstitial configurations in a binary alloy: A-A, A-B, and B-B, which makes it particularly useful for irradiation damage simulations. All the constants of the Hamiltonian are expressed in terms of bond energies that can be computed using first-principles calculations. We implement our ABVI model in kinetic Monte Carlo simulations and perform a verification exercise by comparing our results to published irradiation damage simulations in simple binary systems with Frenkel pair defect production and several microstructural scenarios, with matching agreement found.
Understanding the evolution of infectious disease at the invasion front

Subjects: subject: Evolutionary Biology
subject: FOS: Biological sciences

description: Understanding the occurrence and spread of infectious disease is a major challenge to epidemiologists and evolutionary biologists. As a result of range expansions, invasions and patch colonisation, pathogens encounter highly dynamic host populations, where infection strategies that optimise transmission and exploitation may not be the same across a landscape. My thesis provides some of the first empirical evidence of how disease may evolve when encountering conditions that mimic the core and front of an invading host population. I test for a range of ecological consequences of range expansion on pathogen fitness, and discuss how pathogens might evolve when travelling with their host.

description: The properties of fine-line printed contacts on silicon solar cells, in combination with light-induced plating (LIP), are
investigated. The seed layers are printed using an aerosol system and a new metallization ink called SISC developed at
Fraunhofer ISE. The influence of multiple layer printing on the contact geometry is studied as well as the influence of the
contact height on the line resistivity and on the contact resistance. As the line resistivity of fine-line printed fingers needs to
be reduced by LIP, three different plating electrolytes are tested on solar cells. The observed differences in line resistivity
between f = 5×10-8 Ωm and 2×10-8 Ωm are explained by taking SEM pictures of the grown LIP silver. Finally, the optimum
LIP height for different line resistivities is calculated and experimentally confirmed by processing solar cells with an
increasing amount of LIP silver.
Minimal surfaces in the 3-sphere by desingularizing intersecting Clifford tori

description: For each integer $k \geq 2$, we apply gluing methods to construct sequences of minimal surfaces embedded in the round $3$-sphere. We produce two types of sequences, all desingularizing collections of intersecting Clifford tori. Sequences of the first type converge to a collection of $k$ Clifford tori intersecting with maximal symmetry along these two circles. Near each of the circles, after rescaling, the sequences converge smoothly on compact subsets to a Karcher-Scherk tower of order $k$. Sequences of the second type desingularize a collection of the same $k$ Clifford tori supplemented by an additional Clifford torus equidistant from the original two circles of intersection, so that the latter torus orthogonally intersects each of the former $k$ tori along a pair of disjoint orthogonal circles, near which the corresponding rescaled sequences converge to a singly periodic Scherk surface. The simpler examples of the first type resemble surfaces constructed by Choe and Soret \cite{CS} by different methods where the number of handles desingularizing each circle is the same. There is a plethora of new examples which are more complicated and on which the number of handles for the two circles differs. Examples of the second type are new as well.

description: Asian cobras (genus Naja) are venomous snakes distributed from the Middle East to Southeast Asia. Because cobras often live near humans settlements, they are responsible for a large part of snakebite incidents and as such pose a challenge for public health systems. In the light of growing human populations, correctly mapping the present and future ranges of Asian cobras is therefore important for both biological conservation and public health management. Here, we mapped the potential climatic niches of ten Asian cobra species for both the present and the future, with the aim to quantify changes in climate and human population densities relative to their current and future ranges. Our analyses reveal that cobras that are adapted to dry climates and inhabit islands have narrow climatic niches, while those of mainland species with larger geographic ranges are much wider. We also found a higher degree of fragmentation of future cobra distributions; within the next 50 years, Asian cobras will lose an average of around 60% of their current suitable climatic range. In the near future, Naja mandalayensis, N. sputatrix, N. samarensis, and N. philippinensis are likely to have no accessible suitable climate space left. Besides, a further increase of human populations in this region may also exponentially accelerate the effects of anthropogenic impacts. Solutions for conservation may involve awareness and appropriate use of law to overcome the rate of habitat degradation and the increase of animal trade of Asian cobras, while promoting investment on health systems to avoid snakebite fatalities.

description: Developing animals often use steroid hormones to control important transitions in life stages, and dysregulation of such hormones can lead to severe consequences such as delays in development, malformations, or even death. Steroid hormone production is regulated by protein signals produced in the brain, but we have a limited understanding of the range signals used. Using the fruit fly as a model system, this thesis identified several new proteins that regulate steroid hormone synthesis. Reducing the levels of these proteins resulted in impaired steroid hormone production. These findings suggest that regulation of steroids is more complex than previously thought.

description: A five-dimensional treatment of the Boltzmann equation is used to establish the constitutive equations that relate thermodynamic fluxes and forces up to first order in the gradients for simple charged fluids in the presence of electromagnetic fields. The formalism uses the ansatz first introduced by Kaluza back in 1921, proposing that the particle charge-mass ratio is proportional to the fifth component of its velocity field. It is shown that in this approach, space-time curvature yields thermodynamic forces leading to generalizations of the well-known cross-effects present in linear irreversible thermodynamics.

description: In this thesis we investigate dark matter, a form of matter that so far has only been detected by gravitational interactions, and baryogenesis, the origin of visible matter in our Universe. We work in the framework of supersymmetry, a hypothetical extension of the Standard Model of elementary particles. Combining data from astrophysical and collider experiments, we constrained some of the unknown parameters of the minimal model. We also investigated the mechanism that created visible matter in the early Universe and classified the possible cosmological histories by identifying their common features.

description: The sustainable development strategy in the management of information and communication technology (ICT) is an advanced research sector which provides a theoretical framework for integrating social and environmental responsibilities of business in the development and implementation of the management strategy. This article offers an original management model that integrates the Corporate Social Responsibility (CSR) approach and Green IT, which enables decision makers, governance and strategic alignment of ICT, business and sustainability. The model offers a new vision of decision making through economic opportunities and increasing pressure from stakeholders. This paper reveals the strategic relevance of the model, on the basis of a literature review, and provides guidelines for sustainable business development of effective management systems, and improvement of the economic, social and environmental performance of companies. The proposed framework provides a new generation managerial approach to ICT management strategy that we call "Eco-Strategy".

description: A historical problem for indirect exoplanet detection has been contending with the intrinsic variability of the host star. If the variability is periodic, it can easily mimic various exoplanet signatures, such as radial velocity variations that originate with the stellar surface rather than the presence of a planet. Here we present an update for the HD~99492 planetary system, using new radial velocity and photometric measurements from the Transit Ephemeris Refinement and Monitoring Survey (TERMS). Our extended time series and subsequent analyses of the Ca II H\&K emission lines show that the host star has an activity cycle of $\sim$13 years. The activity cycle correlates with the purported orbital period of the outer planet, the signature of which is thus likely due to the host star activity. We further include a revised Keplerian orbital solution for the remaining planet, along with a new transit ephemeris. Our transit-search observations were inconclusive.

The Impact of Subtropical to Tropical Oceanic Interactions on Tropical Pacific Decadal Variability

Subjects: subject: 40503 Physical Oceanography

description: Slow natural variations of the tropical Pacific Ocean have a worldwide climatic impact which motivates understanding and predicting this low-frequency variability. The Pacific subtropical cells (STCs), an ocean circulation that connects the subtropics to the tropics in each hemisphere, have been proposed to drive such slow variations. In this thesis, we closely analyse different physical mechanisms by which the STCs can act as a driver. We show that variations in the strength of the Southern hemisphere STC as well as the equatorward transport of density compensated temperature anomalies by both STCs play a dominant role in inducing low-frequency variability.

description: A unified treatment for fast and spectrally accurate evaluation of electrostatic potentials subject to periodic boundary conditions in any or none of the three spatial dimensions is presented. Ewald decomposition is used to split the problem into a real-space and a Fourier-space part, and the FFT-based Spectral Ewald (SE) method is used to accelerate the computation of the latter. A key component in the unified treatment is an FFT-based solution technique for the free-space Poisson problem in three, two or one dimensions, depending on the number of non-periodic directions. The computational cost is furthermore reduced by employing an adaptive FFT for the doubly and singly periodic cases, allowing for different local upsampling factors. The SE method will always be most efficient for the triply periodic case as the cost of computing FFTs will then be the smallest, whereas the computational cost of the rest of the algorithm is essentially independent of periodicity. We show that the cost of removing periodic boundary conditions from one or two directions out of three will only moderately increase the total runtime. Our comparisons also show that the computational cost of the SE method in the free-space case is around four times that of the triply periodic case. The Gaussian window function previously used in the SE method, is here compared to a piecewise polynomial approximation of the Kaiser-Bessel window function. With a carefully tuned shape parameter that is selected based on an error estimate for this new window function, runtimes for the SE method can be further reduced. Furthermore, we consider different methods for computing the force, and compare the runtime of the SE method with that of the Fast Multipole Method.

description: The quantum internet holds promise for performing quantum communication, such as quantum teleportation and quantum key distribution (QKD), freely between any parties all over the globe. Such a future quantum network, depending on the communication distance of the requesting parties, necessitates to invoke several classes of optical quantum communication such as point-to-point communication protocols, intercity QKD protocols and quantum repeater protocols. Recently, Takeoka, Guha and Wilde (TGW) have presented a fundamental rate-loss tradeoff on quantum communication capacity and secret key agreement capacity of any lossy channel assisted by unlimited forward and backward classical communication [Nat. Commun. 5, 5235 (2014)]. However, this bound is applicable only to the simplest class of quantum communication, i.e., the point-to-point communication protocols, and it has thus remained open to grasp the potential of a `worldwide' quantum network. Here we generalize the TGW bound to be applicable to any type of two-party quantum communication over the quantum internet, including other indispensable but much more intricate classes of quantum communication, intercity QKD protocols and quantum repeater protocols. We also show that there is essentially no scaling gap between our bound and the quantum communication efficiencies of known protocols. Therefore, our result, corresponding to a fundamental and practical limitation for the quantum internet, will contribute to design an efficient quantum internet in the future.

description: We show that direct Feynman-parametric loop integration is possible for a large class of planar multi-loop integrals. Much of this follows from the existence of manifestly dual-conformal Feynman-parametric representations of planar loop integrals, and the fact that many of the algebraic roots associated with (e.g. Landau) leading singularities are automatically rationalized in momentum-twistor space---facilitating direct integration via partial fractioning. We describe how momentum twistors may be chosen non-redundantly to parameterize particular integrals, and how strategic choices of coordinates can be used to expose kinematic limits of interest. We illustrate the power of these ideas with many concrete cases studied through four loops and involving as many as eight particles. Detailed examples are included as ancillary files to this work's submission to the arXiv.

of the contaminated ingots with respect to the reference. Adding 50 ppmw of iron or 40 ppmw of nickel or chromium
to the silicon feedstock in p-type ingots, the solar cell performances are comparable to the reference in the range of 40

the crystal growth and shunting behaviour.

description: This thesis studies the effect of a protease inhibitor known as z-FA-FMK on the growth of the intracellular parasite Toxoplasma gondii. During infection, the parasite can change from active infectious form to dormant form and eventually form cyst. Dormant parasites in cysts are difficult to be eradicated by currently available drug treatment. In this thesis, we found that z-FA-FMK inhibits Toxoplasma gondii growth and induce them to form cyst through inducing nutrient starvation.

description: The interstitial iron (Fei) concentrations in multicrystalline block-cast silicon (mc-Si) and
monocrystalline Czochralski-grown silicon (Cz-Si) wafers deduced from recombination lifetime measurements are
effectively reduced by annealing the wafers at very low temperature (300-500°C). During annealing the iron
concentration decreases exponentially by more than one order of magnitude. Our results suggest that iron
precipitation in the silicon bulk is the main mechanism responsible for the reduction in the Fei concentration.

description: 24th European Photovoltaic Solar Energy Conference, 21-25 September 2009, Hamburg, Germany; 969-973
description: We study multicrystalline silicon (mc-Si) block cast wafer solar cell material with respect to mechanical
residual stresses at grain boundaries (GBs) related to GB type, details of microstructure, and electrical activity of the GBs.
For this purpose we combine micro-Raman spectroscopy, electron backscatter diffraction, and electron beam induced current
techniques. Stresses of several tens of MPa are found not to influence the electrical activity in block cast mc-Si.
Inhomogeneous distributions of residual stresses and electrical activity are observed along the same GB as well as along
different GBs of the same type. These results are discussed in terms of local variations in the GB microstructure due to the
presence of dislocations superimposed on the GB, their arrangement, intrinsic structure, and impurity decoration.

description: Concentrator optical systems create non-uniform irradiance distributions over the solar cell. Multijunction
solar cells efficiency is sensitive to those spatial and spectral non-uniformities. The first step to evaluate
efficiency losses is to known irradiance distributions created by concentrator optics. In this paper results from raytracing
simulations are presented. However, simulations represent too ideal optical behavior predicting huge
irradiation peaks. Real measurements using a CCD camera and adequate filters have been carried out to obtain the
irradiance peaks that will take place in reality. Results show how simulations predict ‘peak to average’ values much
higher than measured.
On order continuous duals of vector lattices of continuous functions on resolvable spaces

description: A topological space $X$ is called resolvable if it contains a dense subset with dense complement. Using only basic principles, we show that whenever the space $X$ has a resolving subset that can be written as an at most countably infinite union of subsets, in such a way that a given vector lattice of (not necessarily bounded) continuous functions on $X$ separates every point outside the resolving subset from each of its constituents, then the order continuous dual of this lattice is trivial. In order to apply this result in specific cases, we show that several spaces have resolving subsets that can be written as at most countably infinite unions of closed nowhere dense subsets. An appeal to the main result then yields, for example, that, under appropriate conditions, vector lattices of continuous functions on separable spaces, metric spaces, and topological vector spaces have trivial order continuous duals if they separate points and closed nowhere dense subsets. Our results in this direction extend known results in the literature. We also show that, under reasonably mild separation conditions, vector lattices of continuous functions on locally connected $T_1$ Baire spaces without isolated points have trivial order continuous duals. A discussion of the relation between our results and the non-existence of non-zero normal measures is included.

description: All-optical helicity dependent switching (AO-HDS), deterministic control of magnetization by circularly polarized laser pulses, allows to efficiently manipulate spins without the need of a magnetic field. However, AO-HDS in ferromagnetic metals so far requires many laser pulses for fully switching their magnetic states. Using a combination of a short, 90-fs linearly polarized pulse and a subsequent longer, 3-ps circularly polarized pulse, we demonstrate that the number of pulses for full magnetization reversal can be reduced to 4 pulse pairs in a single stack of Pt/Co/Pt. The obtained results suggest that the dual-pulse approach is a potential route towards realizing efficient AO-HDS in ferromagnetic metals.

description: We here report the properties of Wolf-Rayet (W-R) stars in 14 locations in the nearby spiral galaxy M81. These locations were found serendipitously while analysing the slit spectra of a sample of ~150 star-forming complexes, taken using the long-slit and Multi-Object spectroscopic modes of the OSIRIS instrument at the 10.4-m Gran Telescopio Canarias. Colours and magnitudes of the identified point sources in the Hubble Space Telescope images compare well with those of individual W-R stars in the Milky Way. Using templates of individual W-R stars, we infer that the objects responsible for the observed W-R features are single stars in 12 locations, comprising of 3 WNLs, 3 WNEs, 2 WCEs and 4 transitional WN/C types. In diagrams involving bump luminosities and the width of the bumps, the W-R stars of the same sub-class group together, with the transitional stars occupying locations intermediate between the WNE and WCE groups, as expected from the evolutionary models. However, the observed number of 4 transitional stars out of our sample of 14 is statistically high as compared to the 4% expected in stellar evolutionary models.

description: Neural approaches to Natural Language Generation (NLG) have been promising for goal-oriented dialogue. One of the challenges of productionizing these approaches, however, is the ability to control response quality, and ensure that generated responses are acceptable. We propose the use of a generate, filter, and rank framework, in which candidate responses are first filtered to eliminate unacceptable responses, and then ranked to select the best response. While acceptability includes grammatical correctness and semantic correctness, we focus only on grammaticality classification in this paper, and show that existing datasets for grammatical error correction don't correctly capture the distribution of errors that data-driven generators are likely to make. We release a grammatical classification and semantic correctness classification dataset for the weather domain that consists of responses generated by 3 data-driven NLG systems. We then explore two supervised learning approaches (CNNs and GBDTs) for classifying grammaticality. Our experiments show that grammaticality classification is very sensitive to the distribution of errors in the data, and that these distributions vary significantly with both the source of the response as well as the domain. We show that it's possible to achieve high precision with reasonable recall on our dataset.

description: We exhibit new examples of double quasi-Poisson brackets, based on some classification results and the method of fusion. This method was introduced by Van den Bergh for a large class of double quasi-Poisson brackets which are said differential, and our main result is that it can be extended to arbitrary double quasi-Poisson brackets. We also provide an alternative construction for the double quasi-Poisson brackets of Van den Bergh associated to quivers, and of Massuyeau-Turaev associated to the fundamental groups of surfaces.

description: Microtubules are hollow cylindrical polymers composed of the highly negatively-charged (~23e), high dipole moment (1750 D) protein a,b-tubulin. While the roles of microtubules in chromosomal segregation, macromolecular transport and cell migration are relatively well-understood, studies on the electrical properties of microtubules have only recently gained strong interest. Here, we show that while microtubules at physiological concentrations increase solution capacitance, free tubulin has no appreciable effect. For a particular microtubule concentration, we were able to quantify these effects by determining the capacitance and resistance of a single 20 um-long microtubule to be 1.86 x 10^(-12) F and 1.07 x 10^12 Ohms respectively. Further, we observed a decrease in electrical resistance of solution, with charge transport peaking between 20-60 Hz in the presence of microtubules, consistent with recent findings that microtubules exhibit electric oscillations at such low frequencies. Our results show that in addition to macromolecular transport, microtubules also act as charge-storage devices through counterionic condensation across a broad frequency spectrum. We conclude with a hypothesis of an electrically-tunable cytoskeleton where the dielectric properties of tubulin are polymerization-state dependent.
