Abstract
In binary black hole mergers and other highly dynamical spacetimes, the surface of most obvious interest, the event horizon, is often computationally difficult to locate. Instead, it is useful to use quasi-local characterizations of black hole boundaries, such as Marginally Outer Trapped Surfaces (MOTS), the outer-most of which is (often) the apparent horizon. Recent studies have shown that MOTS not only characterize boundaries, but may also be found in black hole interiors. This has been seen in 4D Schwarzschild and Reissner-Nordstrom, as well as in binary black hole mergers. In this thesis, behaviours of MOTS|and their open generalization, Marginally Outer Trapped Open Surfaces (MOTOS)|in the interior of five-dimensional black holes are studied; both static (Schwarzschild), and rotating (Myers-Perry). Similar to four-dimensions, we find infinitely many self-intersecting MOTS in 5D Schwarzschild. We find finitely many self-intersecting MOTS in Myers-Perry, finding fewer as the rotation increases. However, we do find oscillations of the MOTOS, which is novel behaviour.

description: Cardiocondyla is one of the few ant genera in which winged dispersing males coexist with wingless fighter males, which predominantly mate inside their maternal nests. Male polymorphism is not genetically determined but induced by environmental conditions (e.g., a decrease in temperature). The factors leading to the production of winged males were studied in more detail by exposing colonies of C. obscurior to a specific set of rearing conditions. A "stressful" environmental condition (rearing temperature lowered on average by 5°C) experienced for at least two days, the decrease of temperature by a minimum of 3°C, and the addition of protein-rich food triggered the development of winged males. In contrast, a smaller decrease in temperature, starvation, encounters with workers from other species, and encounters with alien, conspecific winged males did not induce the production of winged males. Colonies differed strongly in their reaction to changing environmental conditions, which might indicate a difference in their threshold sensitivity. The results are discussed and compared with data from other dimorphic insect species.

description: Evaluating and guaranteeing customer satisfaction in the long-term is an integral part of quality management in libraries. Quality is defined as “all of the characteristics and features of a product or a service, which relate to their suitability for fulfilling fixed or given requirements” [EOQ 1976] and it is determined by the subjective evaluation of the customer. Surveys are used to gather individual opinions and to compress them into an overall evaluation, which then serves as the basis for an analysis of strengths and weaknesses. This article is based on the analysis of a best practice report conducted by the Central Library of Forschungszentrum Jülich. An online survey performed in 2007 was used to assess the satisfaction and expectations of library users and the results were incorporated into an improvement list. “User satisfaction” is particularly important in a special library. There is no such thing as an homogenous user. Instead, a wide variety of user groups exist and the library must adequately react to their individual needs. For the Central Library of Forschungszentrum Jülich, customer orientation means continuously assessing customer satisfaction, further developing the range of information services available in order to meet high quality demands, and optimising products and services with the involvement of the customer.

description: The Two-Higgs-Doublet-Standard Model-Axion-Seesaw-Higgs-Portal inflation (2hdSMASH) model consisting of two Higgs doublets, a Standard Model (SM) singlet complex scalar and three SM singlet right-handed neutrinos can embed axion dark matter, neutrino masses and address inflation. We report on an investigation of the inflationary aspects of 2hdSMASH and its subsequent impact on low energy phenomenology. In particular, we identify inflationary directions for which the parameter values required for successful inflation do not violate perturbative unitarity and boundedness-from-below conditions. By analyzing the renormalization-group flow of the parameters we identify the necessary and sufficient constraints for running all parameters perturbatively and maintaining stability from the electroweak to the PLANCK scale. We determine typical benchmark points satisfying theoretical and experimental constraints which can be potentially probed by future colliders.

description: Given current discrepancy in muon $g-2$ and future dedicated efforts to measure muon electric dipole moment (EDM) $d_\mu$, we assess the indirect constraints imposed on $d_\mu$ by the EDM measurements performed with heavy atoms and molecules. We notice that the dominant muon EDM effect arises via the muon-loop induced 'light-by-light' $CP$-odd amplitude $\propto{\bf B}{\bf E}^3$, and in the vicinity of a large nucleus the corresponding parameter of expansion can be significant, $eE_{\rm nucl}/m_\mu^2 \sim 0.04$. We compute the $d_\mu$-induced Schiff moment of the $^{199}$Hg nucleus, and the linear combination of $d_e$ and semileptonic $C_S$ operator (dominant in this case) that determine the $CP$-odd effects in ThO molecule. The results, $d_\mu(^{199}{\rm Hg}) < 6\times 10^{-20}e$cm and $d_\mu({\rm ThO}) < 2\times 10^{-20}e$cm, constitute approximately three- and nine-fold improvements over the limits on $d_\mu$ extracted from the BNL muon beam experiment.

description: We study two-point functions of single-trace half-BPS operators in the presence of a supersymmetric Wilson line in $\mathcal{N}=4$ SYM. We use inversion formula technology in order to reconstruct the CFT data starting from a single discontinuity of the correlator. In the planar strong coupling limit only a finite number of conformal blocks contributes to the discontinuity, which allows us to obtain elegant closed-form expressions for two-point functions of single-trace operators $\mathcal{O}_J$ of weight $J=2,3,4$. Our final result passes a number of non-trivial consistency checks: it has the correct discontinuity, it satisfies the superconformal Ward identities, it has a sensible expansion in both defect and bulk OPEs, and is consistent with available results coming from localization. The method is completely algorithmic and can be implemented to calculate correlators of arbitrary weight.

title: Experimental and computational studies of the effect of lung surfactant protein-B fragment, SP-B₁₋₉, on m lipid bilayers
Creators: name: Jyothini, Abinu Ajithan
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: The effect of lung surfactant protein fragment, SP-B₁₋₉, on a model lipid bilayer was investigated. Lung surfactants are lipid-protein complex mixtures that help in reducing the effort needed for breathing by lowering the surface tension that builds up at the alveolar air-liquid interface. Recent research using deuterium NMR to examine the impact of SP-B fragments on bilayer model membranes found that the SP-B fragment, SP-B(1-25, 63-78), had a greater effect on the lipid chain acyl chain orientational order than the fragment, SP-B (8-25, 63- 78). Both of these SP-B fragments include the first and last helices of SP-B, however they vary in the presence or absence of the insertion motif SP-B₁₋₇. This indicates that the insertion motif may contribute to the ability of SP-B to promote the bilayer reorganisation required for lung surfactant function. To gain a better understanding of the insertion motif’s interaction with surfactant lipids, we used deuterium NMR and GROMACS molecular dynamic simulations to examine the effect of SP-B₁₋₉, on the acyl chain order of a lipid bilayer comprised of the lipids DPPC and POPG in a 7:3 ratio. 2H NMR studies with DPPC-d62/POPG (7:3) and SP-B₁₋₉ at peptide-to-lipid ratios of 0.066 and 0.098 revealed no detectable effects in the first moment and order parameter profiles. Even after freezing and thawing the samples, no significant impact of the peptide was detected. On the other hand, MDsimulations of lipid bilayers containing DPPC/POPG(7:3) and SP-B₁₋₉ at a peptide-to-lipid ratio of 0.031 showed a reduction in the acyl chain orientational order of the lipid chain. This difference between the simulation results and the experiments could be due to the aggregation of the peptides in the experiments. MD simulations also reveal the peptide’s average orientation and conformation in the lipid bilayer. It was found that the residues at peptide positions 5, 6, and 7 (Leucine, Proline, and Tyrosine, respectively) had the potential to be part of a helical segment with an average helicity of approximately 45%. The peptide seems to slope into the bilayer, with the last few residues at the N-terminal end remaining horizontal to the bilayer plain, not going closer to the bilayer centre.

description: Brain development relies on dynamic morphogenesis and interactions of neurons. Filopodia are thin and highly dynamic membrane protrusions that are critically required for neuronal development and neuronal interactions with the environment. Filopodial interactions are typically characterized by non-deterministic dynamics, yet their involvement in developmental processes leads to stereotypic and robust outcomes. Here, we discuss recent advances in our understanding of how filopodial dynamics contribute to neuronal differentiation, migration, axonal and dendritic growth and synapse formation. Many of these advances are brought about by improved methods of live observation in intact developing brains. Recent findings integrate known and novel roles ranging from exploratory sensors and decision-making agents to pools for selection and mechanical functions. Different types of filopodial dynamics thereby reveal non-deterministic subcellular decision-making processes as part of genetically encoded brain development.

description: Three peptides comprising mono-, di-, and tri-fluoroethylglycine (MfeGly, DfeGly, and TfeGly) residues alternating with lysine were digested by readily available proteases (elastase, bromelain, trypsin, and proteinase K). The degree of degradation depended on the enzyme employed and the extent of fluorination. Incubation of the peptides with a microbial consortium from garden soil resulted in degradation, yielding fluoride ions. Further biodegradation studies conducted with the individual fluorinated amino acids demonstrated that the degree of defluorination followed the sequence MfeGly > DfeGly > TfeGly. Enrichment of the soil bacteria employing MfeGly as a sole carbon and energy source resulted in the isolation of a bacterium, which was identified as Serratia liquefaciens. Cell-free extracts of this bacterium enzymatically defluorinated MfeGly, yielding fluoride ion and homoserine. In silico analysis of the genome revealed the presence of a gene that putatively codes for a dehalogenase. However, the low overall homology to known enzymes suggests a potentially new hydrolase that can degrade monofluorinated compounds. 19F NMR analysis of aqueous soil extracts revealed the unexpected presence of trifluoroacetate, fluoride ion, and fluoroacetate. Growth of the soil consortium in tryptone soya broth supplemented with fluoride ions resulted in fluoroacetate production; thus, bacteria in the soil produce and degrade organofluorine compounds.

title: Why people tolerate transgressive leaders: Social identity advancement, group prototypicality, and charisma
Creators: name: Davies, Ben
Publisher: name: University of Kent
Year: 2022

description: Transgressive leaders have the potential to cause widespread disruption and damage to organisations. Not only can leaders' misconduct have economic, legal, and social ramifications for organisational functioning, but national leaders who violate established rules may also threaten the social fabric of entire societies. Despite these implications, transgressive leadership is a rampant problem within groups and organisations, and such leaders are often treated sympathetically by in-group members. This thesis aimed to identify some of the social psychological constructs and mechanisms that encourage followers to tolerate the transgressive behaviours of their leaders. Across eight studies using a variety of methods, populations, and contexts, I demonstrate the role of group prototypicality, identity advancement, and charisma in upholding the lenient treatment of transgressive leaders. Overall, findings from this thesis suggest that leaders who are perceived as having the group's best interests at heart are treated more sympathetically following their transgression. In part, this is because advancing group interests contributes towards perceptions of group prototypicality and charisma, which subsequently also encourage followers to treat their leader lightly. Additionally, perceptions of identity advancement encourage followers to rationalise the transgressive behaviour of their leader by downplaying how unethical their misconduct is, which paves the way for continued support of transgressive leaders. The research in this thesis has theoretical implications for the social identity theory of leadership, subjective group dynamics theory, and the deviance credit model. This research also provides practical insights into the difficulties faced in managing or mitigating transgressive leadership, and point to potential mechanisms that may be targeted by future interventions in resolving such a key societal problem.

description: It is confirmed by measurements of fluorescence spectra and quantum yields that the fluorescence in tolan originates from the same state that causes the absorption band at lowest energy. The temp. dependence of the fluorescence quantum yield shows that this state is thermally deactivated with an activation energy of EA = 14.0 kJ/mol. Geometry optimizations of the states S0, S1, and T1 of tolane with the semiempirical AM1 method lead to planar structures with D2h symmetry. Potential energy curves along the triple-bond stretching coordinates have been calcd. for several low-lying excited states with a combination of the AM1 and the INDO/S methods. It is found that for large triple-bond lengths, the 1Au-state with sp* character becomes the lowest excited singlet state. It is proposed that thermal deactivation of S1(11Blu) leads to this state. Nonvertical excitation of 11Au could explain the weak lines found in supersonic jet expts. below the onset of the 11Ag -> 11Blu transition.

description: In this paper we investigate optimal control problems perturbed by random events. We assume that the control has to be decided prior to observing the outcome of the perturbed state equations. We investigate the use of probability functions in the objective function or constraints to define optimal or feasible controls. We provide an extension of differentiability results for probability functions in infinite dimensions usable in this context. These results are subsequently combined with the optimal control setting to derive a novel Pontryagin's optimality principle.

subject: 540 Chemie

description: The two-photon excitation spectra of biphenyl and fluorene in dil. soln. were measured up to 50,000 cm-1. Both spectra exhibit a medium intense band system in the range 32,000-42,000 cm-1, and a strong band above 45,000 cm-1. The lowest frequency feature is assigned to a B3 symmetry transition in biphenyl and the corresponding B2 transition in fluorene. The polarization of the higher bands leads to the assignment of 2 A states at 38,000 and 47,000 cm-1. The origin of the electronically excited states of the biphenyl chromophore is discussed by simple composite mol. considerations as well as CNDO CI calcns. The latter give a semiquant. picture of transition energies and transition probabilities for 1- and 2-photon allowed excitations. A compilation of 1-photon spectra and calcns. from the literature is included in the anal. to provide a consistent picture of the electronically excited states of the biphenyl chromophore up to 50,000 cm-1.

description: One central challenge for humanity is to mitigate and adapt to an ongoing climate and biodiversity crisis while providing resources to a growing human population. Ecological intensification (EI) aims to maximize crop productivity while minimizing impacts on the environment, especially by using biodiversity to improve ecosystem functions and services. Many EI measures are based on trophic interactions between organisms (e.g. pollination, biocontrol). Here, we investigate how research on multitrophic effects of biodiversity on ecosystem functioning could advance the application of EI measures in agriculture and forestry. We review previous studies and use qualitative analyses of the literature to test how important variables such as land-use parameters or habitat complexity affect multitrophic diversity, ecosystem functions and multitrophic biodiversity–ecosystem functioning relationships. We found that positive effects of biodiversity on ecosystem functions are prevalent in production systems, largely across ecosystem function dimensions, trophic levels, study methodologies and different ecosystem functions, however, with certain context dependencies. We also found strong impacts of land use and management on multitrophic biodiversity and ecosystem functions. We detected knowledge gaps in terms of data from underrepresented geographical areas, production systems, organism groups and functional diversity measurements. Additionally, we identified several aspects that require more attention in the future, such as trade-offs between multiple functions, temporal dynamics, effects of climate change, the spatial scale of the measures and their implementation. This information will be vital to ensure that agricultural and forest landscapes produce resources for humanity sustainably within the environmental limits of the planet.

description: Carrot is the cheap source of carotenoids, vitamins, and minerals and has the potential to tackle chronic Vitamin A malnutrition in Ethiopia and generate income for resource-poor farmers. However, its productivity was low due to low soil fertility as one of the many constraints. Therefore, this field experiment was conducted to assess the response of Nantes carrot variety to blended NPS and KCl fertilizer rates at Sodo Zuria Woreda. The experiment consisted of four rates of NPS (0, 50, 100 and 150 kg/ha1) and four rates of KCl (0, 71, 142 and 213 kg/ha1) fertilizers in factorial arrangement and laid out in randomized complete block design with three replications. The results of analyses of variance revealed that NPS and KCl fertilizers as well as the interaction effects of the two fertilizers had significant effects on yield components and root yield of the commercial variety except root length, which was not significantly influenced by interaction effects of the two fertilizers. The highest total and marketable root yield of 30.5 and 24.6 t ha-1, respectively, was obtained by the combined application of 150 kg/ha1 NPS and 213kg/ha1KCl fertilizers. The highest marginal rate of return (MRR %) (2755.97%) was obtained from 150 kg NPS ha-1 without KCl fertilizer application. However, the combined application of 150 kg ha-1 NPS and 213 kg ha-1 KCl fertilizers bear the highest total net benefit of 118881 Birr per hectare with MRR of 1385%, which was above the minimum acceptable range. This could be used to obtain high root yield and better economic return to producers in the study area.

description: Due to the increased popularity of herbomineral preparations in the healthcare sector, a new proprietary herbomineral formulation was formulated consisting of ashwagandha root extract and three minerals viz. zinc chloride, magnesium gluconate, and sodium selenate. The objective of the study was to evaluate the in vitro effect of Biofield Energy Healing (The Trivedi Effect®) on the test formulation using murine splenocyte cells. The herbomineral formulation was divided into two parts; one defined as the control, while the other part was treated with the Biofield Energy Healing Treatment performed from a remote distance by twenty renowned Biofield Energy Healers (The Trivedi Effect®) and defined as the Biofield Treated formulation. The splenocyte cells were exposed to test formulations at concentration from 0.00001053 to 10.53 µg/mL and were analyzed after 48 hours for cell viability using MTT assay. The expression of the cytokines (TNF-α, IFN-γ, IL-1β, and MIP-1α) was determined using ELISA assay. The cell viability data showed that all the tested concentration ranges were found to be safe with percentage cell viability at more than 80%. Further, TNF-α expression was significantly inhibited in the Biofield Treated test formulation group with respect to the vehicle control, while at 0.001053 and 0.1053 µg/mL, the expression was suppressed by 1.70% and 8.16%, respectively in the Biofield Treated test formulation compared to the untreated formulation. However, a significant immunosuppression was reported in IFN-γ expression at 0.00001053, 0.0001053, 0.01053, 0.1053, and 1.053 µg/mL by 12.63%, 2.31%, 8.31%, 9.15%, and 7.86%, respectively in the Biofield Treated test formulation compared with the untreated test formulation. The MIP-1α expression was inhibited by 8.31%, 21.53%, and 8.70% at 0.0001053, 0.01053, and 0.1053 µg/mL, respectively in the Biofield Treated formulation compared with the untreated test formulation. However, IL-1β expression was significantly suppressed by 19.72% at concentration 0.00001053 µg/mL in the Biofield Treated test formulation compared with the untreated test formulation. Thus, the down-regulation of tested cytokines and chemokines in the Biofield Energy Healing test formulation might be applicable for controlling acute and chronic inflammation in many clinical diseases. Overall, the results demonstrated that The Trivedi Effect®- Biofield Energy Healing (TEBEH) has the capacity to potentiate the immunomodulatory activity of the test formulation, which can be useful against autoimmune disorders. Biofield Treated Test formulation may also be useful in anti-aging, anti-inflammatory, stress management and in preventing immune-mediated tissue damage in organ transplants by improving overall health and quality of life.

description: A method is presented to describe multiple resonant nonlinear spectra in the presence of strong laser fields. The Liouville equation for the d. operator of the mol. system is transformed to a time-independent linear equation system. This can be easily solved rigorously by numerical methods or, after partitioning into a strong-field part and a perturbation, the soln. can be obtained anal. by a novel perturbative approach. The results account for power broadening. Rabi splitting of signals, and power-induced extra resonances, the latter being related to the pure dephasing-induced resonances in the weak-field limit. The method can be applied to a large no. of multiple resonant nonlinear spectroscopies, esp. CARS, CSRS, coherent Rayleigh scattering and sum- or difference-frequency generation.

description: Laser-induced spin transport is a key ingredient in ultrafast spin dynamics. However, it remains debated to what extent ultrafast magnetization dynamics generates spin currents and vice versa. We use time- and spin-resolved photoemission spectroscopy to study an antiferromagnetically coupled Gd/Fe bilayer, a prototype system for all-optical switching. Spin transport leads to an ultrafast drop of the spin polarization at the Gd surface, demonstrating angular-momentum transfer over several nanometers. Thereby, Fe acts as spin filter, absorbing spin majority but reflecting spin minority electrons. Spin transport from Gd to Fe was corroborated by an ultrafast increase of the Fe spin polarization in a reversed Fe/Gd bilayer. In contrast, for a pure Gd film, spin transport into the tungsten substrate can be neglected, as spin polarization stays constant. Our results suggest that ultrafast spin transport drives the magnetization dynamics in Gd/Fe and reveal microscopic insights into ultrafast spin dynamics.

subject: 540 Chemie

description: The 2-photon excitation spectrum of anthracene in soln. from 29,000 to 47,000 cm-1 is reported. Two-photon allowed transitions to 1B3g(35,800 cm-1), 2Ag (38,000 cm-1), and 3Ag (43,000 cm-1) were assigned by polarization measurements. These results, with those from 1-photon spectroscopy, agree with calcns. Theor. data suggest assignment of a B3g state to a shoulder at 39,000 cm-1 in the 2-photon spectrum.

title: Marine icing sensor array for measuring ice thickness

description: Marine Icing is the process of ice accumulation on ships and other offshore structures in cold regions that can create serious working conditions besides the adverse effects to the offshore operations efficiency. Monitoring of icing conditions together with a number of de-icing strategies is therefore important in decreasing the safety hazards and increase the working effectiveness. Detection of the ice accretion rate on the offshore structures is a challenge due to the harsh environment and the multiphase property of the ice. This thesis is focused on developing a low cost array sensor for the ice accretion detection applicable to the harsh marine environments. We utilized a stray-capacitance technique that encodes a layered multiphase icing accretion uniquely. Capacitive sensors are popular in diverse industrial settings due to their relative simplicity, robustness and low cost. The sensor transducers are compatible with the printed circuit board technology which made this research time effective. The thesis is based on three distinct publications, two journal papers (IEEE, MDPI) and one peer-reviewed conference paper (IEEE), each in a separate chapter. All publications include a theoretical background, simulations, and experimental validation. The underlying novel approach that is more or less shared in all applications is the use of linearly independent sensor array for unique multiphase ice detection. The first two papers utilize a different inter-electrode spacing array but a different signal conditioning algorithm. The third paper then uses an array of constant spacing but different dielectric layer height. As stated above, the main objective of this work is to measure the multiphase icing accretion which consists of water above ice, the real situation which has not been addressed to date. A number of different techniques have been developed over the last two decades mainly as a response to the rapidly expanding offshore oil&gas in northern regions, offshore wind power generation, or shipping across or fishing in arctic waters. This thesis outlines three methods that can be directly applied to these industries.

Two-photon spectroscopy of dipole-forbidden transitions. I. Dipole-forbidden transitions and double excited configurations in the CNDO-CI methods
Creators: name: Dick, Bernhard

subject: 540 Chemie

description: The applicability was investigated of CNDO/S-type methods for the calcn. of optical spectra of mols. with the special implication that the calcns. should not only describe the intense, dipole-allowed transitions which dominate the 1-photon absorption spectrum but also those transitions which are 1-photon forbidden in 1st order approxn. Such a method is well suited to predict dipole allowed and dipole forbidden transitions at a similar level of accuracy if doubled excited configurations are taken into account. In spite of the lack of perfect pairing in NDO methods there are still 2 types of states which exhibit a different sensitivity towards correlation effects. Therefore, the approxn. used to describe the R-dependence of the Coulomb repulsion gains much more importance than in cases where mainly dipole allowed transitions are of interest. These findings confirm results obtained earlier from theories for which the pairing theorem is valid. The calcd. data show an excellent stability with respect to further increase of the no. of configurations if at least ~200 energy selected configurations are taken into account.
