description: By using nanosecond laser pulses at 532-nm wavelength, we have studied the nonlinear optical properties of composites which consist of mono-functional 1,2-dihydro-1,2-methanofullerene[60]-61-carboxylic acid (FCA) and poly(styrene-co-4-vinylpyridine). The optical limiting performance of FCA itself is poorer than that of its parent C60, while FCA incorporated with polystyrene shows better optical limiting responses, with the limiting threshold reduced by about 35%. In addition, the FCA gives slightly stronger photoluminescence emission than that of both C60 and FCA/polymer composites. The possible sources for the improvement in the optical limiting are discussed.

description: It has been conjectured that spontaneous chiral symmetry breaking in strongly coupled vectorlike gauge theories falls into only three different classes, depending on the gauge group and the representations carried by the fermions. We test this proposal by studying SU(2), SU(3) and SU(4) lattice gauge theories with staggered fermions in different irreducible representations. Staggered fermions away from the continuum limit should, for all complex representations, still belong to the continuum class of spontaneous symmetry breaking. But for all real and pseudo-real representations we show that staggered fermions should belong to incorrect symmetry breaking classes away from the continuum, thus generalizing previous results. As an unambiguous signal for whether chiral symmetry breaks, and which breaking pattern it follows, we look at the smallest Dirac eigenvalue distributions. We find that the patterns of symmetry breaking are precisely those conjectured.

description: Cells are constantly sensing and adapting to changes in conditions. Protein post-translational regulation is one of the fastest mechanism used by cells to relay signals from sensors to effectors during such adaptations. Mass spectrometry allows for the study of posttranslational modifications on a very large scale and has been extensively applied to study protein phospho- rylation. On the order of 75% of human proteins have been estimated to be phosphorylated and approximately 160,000 human phosphosites are listed in public repositories. This wealth of knowledge, remains mostly uncharacterized with around 5% of human phosphosites having an annotated regulatory role or known regulatory kinase. Devising ways to study the functional importance of phosphosites is therefore a crucial research question. The recognition of target sites by a kinase is thought to be determined by a short contiguous sequence motif around the target phosphosite. It has been reported that kinases can, in some cases, recognize a 3D epitope instead of a linear peptide sequence. However, the extent by which 3D epitopes are important for kinase recognition is unknown. To study the usage of 3D kinase recognition motifs, I firstly examined if known in vitro and in vivo human kinase targets can be explained by 3D epitopes. For this I devised a computational pipeline mapping known kinase target phosphosites to structural models. Using these I identified potential cases where the important specificity determinant residues are not observed in contiguous sequences in the targets but may exist as a 3D epitope, and performed docking simulations to examine the possible kinase interactions. The 3D epitope examples were found to be rather exceptions than a rule, and the analysis confirms the general rule of linear motif recognition by kinases. To better predict phosphorylation of high functional relevance I analysed phosphosites that are highly conserved across species within protein domains families. These regions of conserved phosphorylation, defined as phosphorylation hotspots, were determined us- ing phosphosite data for a total of 40 eukaryotic species. A total of 241 domain regions were identified as hotspots within 162 domain families that were then mapped to proteins structures. These regions were shown to predict known regulatory sites and overlap with important structural features (i.e. protein interfaces and residues near or at catalytic sites). To further study the regulatory regions of protein domains I searched for regions of conserved ubiquitination and/or a high degree of recurrent mutations found in cancer. Of 68 domains that had enough data for analysis of all 3 types of hotspots I present the analysis of interesting cases and domains containing overlapping PTM and/or mutational hotspots.

description: In this paper (Paper II) we complete our discussion on the results of a comprehensive GEANT simulation of the scientific performance of the AGILE Gamma-Ray Imaging Detector (GRID), operating in the 30 MeV - 50 GeV energy range in an equatorial orbit of height near 550 km. Here we focus on the on-board Level-2 data processing and discuss possible alternative strategies for event selection and their optimization. We find that the dominant particle background components after our Level-2 processing are electrons and positrons of kinetic energies between 10 and 100 MeV penetrating the GRID instrument from directions almost parallel to the Tracker planes (incidence angles > 90 degrees) or from below. The analog (charge) information available on-board in the GRID Tracker is crucial for a reduction by almost three orders of magnitude of protons (and heavier ions) with kinetic energies near 100 MeV. We also present in this paper the telemetry structure of the GRID photon and particle events, and obtain the on-board effective area for photon detection in the energy range ~30 MeV - 50 GeV.

description: This work reports the synthesis and characterization of titanate nanotubes (TiNTs) and their use for the construction of an electrochemical sensor for lead (II) determination in water samples. TiNTs were prepared from TiO2 by a hydrothermal route at 150 °C for 24 h in alkaline conditions. X-ray diffraction (XRD) measurements show peak enlargement and the presence of trititanate with different spaces between layers confirming the production of TiNTs of nanometric dimensions. In addition, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images demonstrated the presence of dispersed, homogenous, and nanometric tubular structure. TiNTs were used for the modification of carbon paste electrodes and evaluated for determination of lead (II) by differential pulse adsorptive stripping voltammetry (DPAdSV). Using the optimized conditions, the developed method provided a linear dynamic range (LDR) from 0.77 to 7.71 µM and limits of detection and quantification of 0.23 and 0.77 µM, respectively. Studies of addition and recovery in spiked water sample were performed, obtaining a recovery of 104.6%. A repeatability study resulted in a relative standard deviation of 11% for consecutive measurements. Using the same electrode, a reproducibility study provided a relative standard deviation of 3.9%.

description: For any Legendrian knot $K$ in standard contact ${\mathbb R}^3$ we relate counts of ungraded ($1$-graded) representations of the Legendrian contact homology DG-algebra $(\mathcal{A}(K),\partial)$ with the $n$-colored Kauffman polynomial. To do this, we introduce an ungraded $n$-colored ruling polynomial, $R^1_{n,K}(q)$, as a linear combination of reduced ruling polynomials of positive permutation braids and show that (i) $R^1_{n,K}(q)$ arises as a specialization $F_{n,K}(a,q)\big|_{a^{-1}=0}$ of the $n$-colored Kauffman polynomial and (ii) when $q$ is a power of two $R^1_{n,K}(q)$ agrees with the total ungraded representation number, $\operatorname{Rep}_1\big(K, \mathbb{F}_q^n\big)$, which is a normalized count of $n$-dimensional representations of $(\mathcal{A}(K),\partial)$ over the finite field $\mathbb{F}_q$. This complements results from [Leverson C., Rutherford D., Quantum Topol. 11 (2020), 55-118, arXiv:1802.10531] concerning the colored HOMFLY-PT polynomial, $m$-graded representation numbers, and $m$-graded ruling polynomials with $m \neq 1$.

description: This study determined the concentrations of toxic metals including As, Cd, Hg and Pb in commonly consumed crustaceans collected from South Korea. The samples were prepared by wet digestion using HNO3 and H2O2 by microwave assisted combustion. For As, Cd, and Pb, inductively coupled plasma–mass spectrometry (ICP-MS) was used. Hg content was determined using gold amalgation direct mercury analysis (DMA). The analytical techniques were validated by determining the correlation coefficients, limits of detection and quantification, coefficients of variance, spiking, and accuracy by analysis of an oyster tissue certified reference material (NIST CRM-1566b). The distribution of toxic metals was determined in whole, muscles, and digestive tracts of crustaceans. Furthermore, to provide information on consumer safety, risk assessment in terms of estimated dietary daily/weekly intake, target hazard quotient, and hazard index values was performed. The concentration (mg/kg) was in decreasing order of As (2.17–6.05) > Cd (0.154–4.57) > Pb (0.033–0.128) > Hg (0.011–0.086). The estimated dietary daily/weekly intake, target hazard quotient, and hazard indices were compared with the standards established by United States Environmental Protection Agency, and Joint Food and Agriculture Organization/World Health Organization Expert Committee on Food Additives and were below the threshold values. The analyzed crustaceans are not expected cause threats to consumers upon normal consumption.

description: The widespread use of ML-based decision making in domains with high societal impact such as recidivism, job hiring and loan credit has raised a lot of concerns regarding potential discrimination. In particular, in certain cases it has been observed that ML algorithms can provide different decisions based on sensitive attributes such as gender or race and therefore can lead to discrimination. Although, several fairness-aware ML approaches have been proposed, their focus has been largely on preserving the overall classification accuracy while improving fairness in predictions for both protected and non-protected groups (defined based on the sensitive attribute(s)). The overall accuracy however is not a good indicator of performance in case of class imbalance, as it is biased towards the majority class. As we will see in our experiments, many of the fairness-related datasets suffer from class imbalance and therefore, tackling fairness requires also tackling the imbalance problem. To this end, we propose AdaFair, a fairness-aware classifier based on AdaBoost that further updates the weights of the instances in each boosting round taking into account a cumulative notion of fairness based upon all current ensemble members, while explicitly tackling class-imbalance by optimizing the number of ensemble members for balanced classification error. Our experiments show that our approach can achieve parity in true positive and true negative rates for both protected and non-protected groups, while it significantly outperforms existing fairness-aware methods up to 25% in terms of balanced error.

description: At an age when breastfeeding is the optimal nutritional support for infants, oral drug delivery can be challenging. In the past, the concept of drug delivery during breastfeeding was developed as a means to address challenges in low-income countries by facilitating administration using solid dosage forms without the need for clean water. Hereby, a silicone nipple shield, containing a formulation inside its teat, is meant to be worn by a mother during breastfeeding, enabling drug delivery to the sucking infant through the flow of human milk. Furthering past research, this doctoral work aimed to investigate novel dosage forms for this application, including a fibrous matrix and a gel formulation, as well as the clinical potential, feasibility, and acceptability of therapeutic delivery during breastfeeding. In a clinical context, a descriptive qualitative study revealed the need for alternative infant oral drug delivery technologies in high-resource settings, and parents' and nursing staff's positive response to the concept of drug delivery during breastfeeding. Findings were supported by the anecdotal evidence of difficulties in infant compliance and accurate dosing, and indicated high relevance for a use case in neonatal intensive care. Formulation investigations included zinc sulphate loaded non-woven fibre mats, and iron sulphate loaded liquid-core alginate hydrogels, using a modified and a commercially available nipple shield design. While full release during breastfeeding simulation was not achieved, both formulations enabled superior delivery of their loaded therapeutic dose compared to previously studied dosage forms. In addition, a clinical feasibility study involving the delivery of vitamin B12 from a commercially available nipple shield during breastfeeding was conducted, supported by a qualitative mixed methods approach. Results illustrated the successful delivery of vitamin B12 to breastfed infants and unanimous maternal advocacy for the availability of therapeutic delivery during breastfeeding in the future.

description: The mirror twin Higgs (MTH) addresses the little hierarchy problem by relating every Standard Model (SM) particle to a twin copy, but is in tension with cosmological bounds on light degrees of freedom. Asymmetric reheating has recently been proposed as a simple way to fix MTH cosmology by diluting the twin energy density. We show that this dilution sets the stage for an interesting freeze-in scenario where both the initial absence of dark sector energy and the feeble coupling to the SM are motivated for reasons unrelated to dark matter production. We give the twin photon a Stueckelberg mass and freeze-in twin electron and positron dark matter through the kinetic mixing portal. The kinetic mixing required to obtain the dark matter abundance is of the loop-suppressed order expected from infrared contributions in the MTH.

description: This study was aimed to develop a sensitive and accurate method for the determination of lead in urine. Dispersive liquid-liquid microextraction (DLLME) was applied prior to slotted quartz tube – flame atomic absorption spectrometry (SQT-FAAS). Dithizone was employed in generating water-insoluble forms of lead to isolate the analyte in the microextraction. All variables having a direct effect on extraction and instrumental outputs were systematically optimized. The detection limit was 0.5 µg L−1 which indicates a 305-fold enhancement compared to conventional FAAS. The wide linear range is between 2.0 and 250 µg L−1 with a high regression coefficient (0.9998). Urine samples were used in order to examine the practical application of the developed method. The recovery values were between 98.2 and 107.0%.

description: The directed and elliptic flow of protons and negative pions in 4.2A GeV/c C+C collisions is studied using the Fourier analysis of azimuthal distributions. It is found that the protons exhibit pronounced directed flow, while the flow of pions is either non existent or too weak to be detected experimentally. Also, it is found that in the entire rapidity interval the elliptic flow is very small if not zero. These results are confirmed by the Quark-Gluon-String Model (QGSM) and the relativistic transport model (ART 1.0), except that these models predict very weak antiflow of pions. The more detailed comparison with the QGSM suggests that the decay of resonances and rescattering of secondaries dominantly determine the proton and negative pion flow at this energy.

description: In my thesis I discuss a very influential and widely accepted thesis on the resacralisation of the Holy Roman Empire by Emperor Frederick Barbarossa (1152 – 1190) and Rainald of Dassel (chancellor 1156 – 1159, archbishop of Cologne 1159 – 1167). I first trace the history of this opinion, showing how scholars gradually came to consider sacrum imperium, the phrase from which the title Holy Roman Empire evolved, as the motto of Frederick and Rainald’s imperial ideology. In the postwar period the translation of the bodies of the Three Kings from Milan to Cologne in 1164 by Rainald of Dassel, the canonisation of Charlemagne in 1165, the design of the Cappenberg head, the Barbarossa chandelier and the reliquary shrine of Saint Charlemagne were reinterpreted as elements of Frederick’s plan to resacralise the state. In my thesis I show that there was no such plan. The state had always been both holy and Roman to an extent, but the terminology changed in the twelfth century because of the influence of classical antiquity via Byzantium and Italy. Meanwhile, Frederick’s part in the canonisation of Charlemagne and the visual elaboration of his cult shows how the German magnates and the canons of Aachen similarly reached back to their own founder figure, Charlemagne, to celebrate their unity and legitimise their inherited authority. However, while Frederick commissioned the Barbarossaleuchter to celebrate his grand Easter diet of 1174, the Karlsschrein was a project of Aachen’s Marienstift and the burghers.

description: We outline a general strategy developed for the analysis of critical models, which we apply to obtain a heuristic classification of all universality classes with up to three field-theoretical scalar order parameters in $d=6-ε$ dimensions. As expected by the paradigm of universality, each class is uniquely characterized by its symmetry group and by a set of its scaling properties, neither of which are built-in by the formalism but instead emerge nontrivially as outputs of our computations. For three fields, we find several solutions mostly with discrete symmetries. These are nontrivial conformal field theory candidates in less than six dimensions, one of which is a new perturbatively unitary critical model.

It is a highly robust microorganism with a high tolerance for toxic conditions, making it an ideal candidate for the remediation of waste materials by metabolism. Our societies produce large amounts of waste materials, which require processing and safe disposal, but could instead be used as resources to produce fuel and energy or sustainably recycled into new materials. R. palustris can be used to process waste glycerol (a byproduct of biodiesel manufacture), and naturally produces hydrogen gas (a clean-burning fuel) as a byproduct of this process. R. palustris could potentially be used to bioremediate other waste materials and could be engineered to manufacture other useful products from this process. This thesis reports discoveries regarding the growth of R. palustris on previously untested substrates and the engineering of R. palustris to improve its utilisation of substrates and add additional metabolic pathways for the sustainable production of valuable compounds. Firstly, new substrates including urea are identified as supporting growth of R. palustris, suggesting that it could be used to process nitrogen-rich agricultural wastes. Nitrogen runoff and pollution pose a significant environmental problem, and safe disposal represents a significant cost to industry. Using R. palustris to bioremediate these wastes, converting them to more valuable materials, would help to offset the costs of waste disposal as well as providing a sustainable source of desirable compounds. Secondly, a genetic manipulation system developed to allow the expression of heterologous genes in R. palustris is presented, and newly engineered strains of R. palustris are characterised that are capable of producing the industrially significant compound cyanophycin when R. palustris is grown on glycerol and urea. Finally, strategies are presented for the future development of R. palustris as a bioremediation system and cell-factory for sustainable biotechnology.

description: We show that the predicted probability distributions for any $N$-parameter statistical model taking the form of an exponential family can be explicitly and analytically embedded isometrically in a $N{+}N$-dimensional Minkowski space. That is, the model predictions can be visualized as control parameters are varied, preserving the natural distance between probability distributions. All pairwise distances between model instances are given by the symmetrized Kullback-Leibler divergence. We give formulas for these intensive symmetrized Kullback Leibler (isKL) coordinate embeddings, and illustrate the resulting visualizations with the Bernoulli (coin toss) problem, the ideal gas, $n$ sided die, the nonlinear least squares fit, and the Gaussian fit. We highlight how isKL can be used to determine the minimum number of parameters needed to describe probabilistic data, and conclude by visualizing the prediction space of the two-dimensional Ising model, where we examine the manifold behavior near its critical point.

description: Nickel-base superalloys are widely applied in the hot section of aero engines due to their high temperature capabilities and excellent mechanical properties. For turbine discs, polycrystalline nickel-base superalloys are used where they experience temperatures up to 700ºC and stresses as high as 1000MPa. The manufacturing process, especially the forging and heat treatment, plays a pivotal role towards achieving the final microstructure and mechanical properties needed to withstand this harsh environment. ATI 718Plus® (718Plus) is a polycrystalline multi-phase strengthened nickel-base superalloy for turbine disc applications in aero engines. Its main strengthening phase is $\gamma$’ but it was also found to precipitate the hexagonal $\eta$ phase. This alloy is used for studying the microstructural changes due to recrystallisation and deformation occurring during forging. The body of work includes the testing and characterisation of 718Plus with and without $\eta$. High temperature compression tests were performed in the temperature range of 850 to 1025ºC, strains between 0.4 and 1.2 and strain rates from 0.01 to 1s-1. To analyse the materials behaviour during meta-dynamic recrystallization, a second set of samples was kept in the furnace for 120s after the compression at high temperature before they were water-quenched. The microstructural changes were investigated using both scanning electron microscope (SEM) and transmission electron microscope (TEM) analysis. Dynamic and meta-dynamic recrystallisation were analysed upon their sensitivity on the testing parameters. Interestingly, an increase in recrystallised fraction with strain rate was found, which is in line with reported values on 718Plus but in contrast to similar nickel-base superalloys such as IN718 or Waspaloy. A detailed analysis of TEM specimens revealed that the higher fraction in recrystallised area was due to meta-dynamic recrystallisation during the transfer time between deformation and quench. In the $\gamma$-$\eta$ microstructure the same mechanism could be observed. In addition, lamellar packets of $\eta$ phase were found to inhibit recrystallisation and promote a narrower grain size distribution. The deformation mechanisms of 718Plus during high temperature compression testing was analysed by an extensive TEM study. A number of grains formed deformation twins. This mechanism is commonly found in materials with a low stacking fault energy at low temperatures and/or high strain rates. Initial stages of twinning could be captured and allowed a detailed analysis of the underlying processes. In the $\gamma$-$\eta$ microstructure the deformation characteristics of the $\eta$ were studied. $\eta$ phase adjusted to the strain by breakage and realignment and also by severe bending.

description: Let $n$ be a nonnegative integer. The $n$-th Apéry number is defined by $$ A_n:=\sum_{k=0}^n\binom{n+k}{k}^2\binom{n}{k}^2. $$ Z.-W. Sun ever investigated the congruence properties of Apéry numbers and posed some conjectures. For example, Sun conjectured that for any prime $p\geq7$ $$ \sum_{k=0}^{p-1}(2k+1)A_k\equiv p-\frac{7}{2}p^2H_{p-1}\pmod{p^6} $$ and for any prime $p\geq5$ $$ \sum_{k=0}^{p-1}(2k+1)^3A_k\equiv p^3+4p^4H_{p-1}+\frac{6}{5}p^8B_{p-5}\pmod{p^9}, $$ where $H_n=\sum_{k=1}^n1/k$ denotes the $n$-th harmonic number and $B_0,B_1,\ldots$ are the well-known Bernoulli numbers. In this paper we shall confirm these two conjectures.

 The diagnosis for this large genus is based on Ii (1964). The females are difficult to distinguish from each other, but males are easily recognized by the structure of the pleopods. The species of Siriella are characterized by a short carapace, leaving 1–2 posterior thoracic somites entirely exposed. Eyes are normally developed. Outer margin of antennal scale without setae and terminates in a small spine. Suture at proximal end of antennal scale unclear and often not visible. Endopods of the third to eight thoracic limbs subequal, articulation dividing the sixth joint into two subjoints, sometimes very distinct but more commonly difficult to see. The sixth joint terminates into a tuft of long peculiarly serrated setae, dactylus well developed. Pleopods of the male with well developed biramous pseudobranchiae. The distal setae on the third and fourth pairs often modified. Telson always armed at the apex with three or four small spines and a pair of plumose setae between one or two pairs of stout spines.
To date, 86 species have been described (Anderson 2008). Two species are recorded from New Zealand waters.

description: Women empowerment and poverty reduction are interrelated key driving forces to achieve the sustainable development of a country. However, most of the women farmers in rural areas have lack of access to adequate assets and resources, credit facilities and freedom of decision making within the households. Therefore, women empowerment is a timely important requirement to reduce the household poverty among them. This study was conducted to identify the determinants of empowerment of women farmers and also roles of them in reduction of poverty in Imbulpe Divisional Secretariat (DS) Division in Sri Lanka. In this study, 238 women farmers were selected using simple random sampling method, from purposively identified seven Grama Niladhari (GN) divisions in this area. Primary data was gathered from a field survey using a pre-tested, self-administered questionnaire from May to July 2019. Descriptive statistics and chi-square analysis were used as the statistical methods in data analyzing process. The result revealed that, age, education, monthly income of the respondents, economic resource accessibility, participation in decision making and freedom of mobility act as the determinants of empowerment of women farmers. The moderately significant positive nature of relationship was showed between the age of the women farmers and their role in poverty reduction. And also, the level of education, monthly income, economic resources accessibility of the respondents and participation of decision making within the household of the women farmers were showed moderately significant positive relationship with their role in poverty reduction. Therefore, encourage women farmers as rural entrepreneurs while performing their farming practices to earn additional income, enhance economic resource accessibility and motivate women farmers to express their ideas for enhance the active participation in the household decision making process are timely important requirements to empower women farmers and enhance their role in poverty reduction.

description: Mendelian randomization uses genetic variants as instrumental variables to estimate the causal effect of a risk factor on an outcome using observational data. If a genetic variant is included in a Mendelian randomization study that does not satisfy the instrumental variable assumptions then the causal estimate from traditional instrumental variable methods will be biased. Since Mendelian randomization studies using publicly available summary level data (estimates and standard errors of the genetic associations with the risk factor and the outcome) from large consortia can be performed with relative ease and little expense, the popularity of Mendelian randomization in epidemiological studies has increased dramatically. As such, various methods have been developed in Mendelian randomization that use summary level data and account for possible violations of the instrumental variable assumptions. However, additional Mendelian randomization methods that account for violations in the instrumental variable assumptions are still required. In this dissertation, we introduce robust methods for Mendelian randomization that downweight the contribution of genetic variants with heterogeneous causal ratio estimates. We extend the univariable MR-Egger method to the multivariable setting to account for both measured and unmeasured pleiotropic effects. We also explore the possibility of extending multivariable Mendelian randomization to the factorial setting to estimate statistical interaction effects. Finally, we apply some of the methods we have developed to perform a Mendelian randomization study to investigate the effect of adiposity and body composition measurements on asthma using data from UK Biobank and the GABRIEL consortium.
