description: In this study, we investigated the molecular characteristics of hydrates which were synthesized from gas mixtures containing the two isomers of butane, or the pentane isomers neopentane and isopentane, in excess methane. Thereto various techniques, including Raman spectroscopy, powder and single crystal X-ray diffraction and 13C NMR spectroscopy were employed. It turned out that shape and conformation of the guest molecule and hydrate structure both influence each other. In case of the mixed butane hydrate it could be confirmed that n-butane is enclathrated in its gauche conformation. This was verified by Raman spectroscopy, single crystal X-ray diffraction and calculated data. While isopentane is known as a structure H former, our results from powder X-ray diffraction, 13C NMR and ab initio calculations show that it can be also incorporated into structure II when the hydrate is formed from a neopentane/isopentane/methane gas mixture.

description: As it is well-known, all Vassiliev invariants of degree one of a knot $K\subset R^3$ are trivial. There are nontrivial Vassiliev invariants of degree one, when the ambient space is not $R^3$. Recently, T. Fiedler introduced such invariants of a knot in an $R^1$-fibration over a surface $F$. They take values in the free $Z$-module generated by all the free homotopy classes of loops in $F$. Here, we generalize them to the most refined Vassiliev invariant of degree one. The ranges of values of all these invariants are explicitly described. We also construct a similar invariant of a two-component link in an $\R^1$-fibration. It generalizes the linking number.

description: We formulate a simple effective model to describe molecular interactions in a lipid monolayer. The model represents lipid molecules in terms of two-dimensional anisotropic particles on the plane of the monolayer. These particles interact through forces that are believed to be relevant for the understanding of fundamental properties of the monolayer: van der Waals interactions originating from lipid chain interaction, and dipolar forces between the dipole groups of the molecular heads. Thermodynamic and phase behaviour properties of the model are explored using density-functional theory. Interfacial properties, such as the line tension and the structure of the region between ordered and disordered coexisting regions, are also calculated. The line tension turns out to be highly anisotropic, mainly as a result of the lipid chain tilt, and to a lesser extent of dipolar interactions perpendicular to the monolayer. The role of the two dipolar components, parallel and perpendicular to the monolayer, is assessed by comparing with computer simulation results for lipid monolayers.

Subjects: subject: perceptual activity theory

subject: Letter Spirit domain

description: Perception and mental imagery are often thought of as processes that generate internal representations, but proponents of perceptual activity theory say they are better thought of as guided exploratory activities. The omission of internal representations in the perceptual activity account has led some to see it as computationally implausible. This thesis clarifies perceptual activity theory from a computational perspective, and tests its viability using a computer model called PABLO. The computer model operates in the Letter Spirit domain, which is a framework for creating stylistic variations on the lowercase letters of the Roman alphabet. PABLO is unlike other computer models of perception and mental imagery because it does not use data-structures to represent percepts and mental images. Mental contents are instead modelled in terms of the exploratory activity in which perceptual activity theory says they consist. PABLO also models the flexibility of imagery, and simulates how it can be harnessed and exploited by the system to generate a creative product. PABLO is a first attempt at an implementation of perceptual activity theory, but the results suggest that the theory is computationally viable, and that it has advantages over other theories of mental imagery in the context of creativity.

description: Microfluidics refers to the interdisciplinary technology that deals with handling and processing small amounts of fluids in channels with micrometre-scale dimensions. This technology has arisen as an influential experimental and research platform that presents manifold advantages to diverse fields, including medicine, science, and engineering. Among the various microfluidic subcategories, droplet-based microfluidics has gained significant traction in commercial settings. However, despite this success, several significant challenges remain, including a limited understanding of the underlying physics and mechanisms, complex interactions, device instability, the necessity of surfactants, multiple effective parameters, and a high level of expertise required to operate microfluidic hardware. These challenges have restricted the advancement and utilization of droplet-based microfluidics in further applications. The present thesis mainly focuses on enhancing our comprehension of droplet generation while developing a new application for droplet-based microfluidics. This thesis aims to achieve the following research objectives: (1) designing and fabricating reliable and stable microfluidic devices for generating core-shell droplets, (2) investigating the fundamental physical factors contributing to droplet generation, (3) evaluating the thermal and mechanical endurance of core-shell particles through theoretical and experimental methods, and (4) exploring the potential use of core-shell particles in a digital polymerase chain reaction (PCR).

description: This paper considers some simple surface brightness (SB) estimates for galaxies in the Automated Plate Measuring Machine (APM) catalogue in order to derive homogeneous SB data for a very large sample of faint galaxies. The isophotal magnitude and area are used to estimate the central surface brightness and total magnitude based on the assumption of an exponential SB profile. The surface brightness measurements are corrected for field effects on each UK Schmidt plate and the zero-point of each plate is adjusted to give a uniform sample of SB and total magnitude estimates over the whole survey. Results are obtained for 2.4 million galaxies with blue photographic magnitudes brighter than b_J = 20.5 covering 4300 deg^2 in the region of the south galactic cap. Almost all galaxies in our sample have central surface brightness in the range 20 to 24 b_J mag per arcsec^2. The SB measurements we obtain are compared to previous SB measurements and we find an acceptable level of error of +/- 0.2 b_J mag per arcsec^2. The distribution of SB profiles is considered for different galaxy morphologies for the bright APM galaxies. We find that early-type galaxies have more centrally concentrated profiles.

description: Finite Rate of Innovation (FRI) theory considers sampling and reconstruction of classes of non-bandlimited continuous signals that have a small number of free parameters, such as a stream of Diracs. The task of reconstructing FRI signals from discrete samples is often transformed into a spectral estimation problem and solved using Prony's method and matrix pencil method which involve estimating signal subspaces. They achieve an optimal performance given by the Cramér-Rao bound yet break down at a certain peak signal-to-noise ratio (PSNR). This is probably due to the so-called subspace swap event. In this paper, we aim to alleviate the subspace swap problem and investigate alternative approaches including directly estimating FRI parameters using deep neural networks and utilising deep neural networks as denoisers to reduce the noise in the samples. Simulations show significant improvements on the breakdown PSNR over existing FRI methods, which still outperform learning-based approaches in medium to high PSNR regimes.

description: Purpose: To validate the performance of a commercially-available, CE-certified deep learning (DL) system, RetCAD v.1.3.0 (Thirona, Nijmegen, The Netherlands), for the joint automatic detection of diabetic retinopathy (DR) and age-related macular degeneration (AMD) in color fundus (CF) images on a dataset with mixed presence of eye diseases. Methods: Evaluation of joint detection of referable DR and AMD was performed on a DR-AMD dataset with 600 images acquired during routine clinical practice, containing referable and non-referable cases of both diseases. Each image was graded for DR and AMD by an experienced ophthalmologist to establish the reference standard (RS), and by four independent observers for comparison with human performance. Validation was furtherly assessed on Messidor (1200 images) for individual identification of referable DR, and the Age-Related Eye Disease Study (AREDS) dataset (133821 images) for referable AMD, against the corresponding RS. Results: Regarding joint validation on the DR-AMD dataset, the system achieved an area under the ROC curve (AUC) of 95.1% for detection of referable DR (SE=90.1%, SP=90.6%). For referable AMD, the AUC was 94.9% (SE=91.8%, SP=87.5%). Average human performance for DR was SE=61.5% and SP=97.8%; for AMD, SE=76.5% and SP=96.1%. Regarding detection of referable DR in Messidor, AUC was 97.5% (SE=92.0%, SP=92.1%); for referable AMD in AREDS, AUC was 92.7% (SE=85.8%, SP=86.0%). Conclusions: The validated system performs comparably to human experts at simultaneous detection of DR and AMD. This shows that DL systems can facilitate access to joint screening of eye diseases and become a quick and reliable support for ophthalmological experts.

description: Ranked search results and recommendations have become the main mechanism by which we find content, products, places, and people online. With hiring, selecting, purchasing, and dating being increasingly mediated by algorithms, rankings may determine career and business opportunities, educational placement, access to benefits, and even social and reproductive success. It is therefore of societal and ethical importance to ask whether search results can demote, marginalize, or exclude individuals of unprivileged groups or promote products with undesired features. In this paper we present FairSearch, the first fair open source search API to provide fairness notions in ranked search results. We implement two algorithms from the fair ranking literature, namely FA*IR (Zehlike et al., 2017) and DELTR (Zehlike and Castillo, 2018) and provide them as stand-alone libraries in Python and Java. Additionally we implement interfaces to Elasticsearch for both algorithms, that use the aforementioned Java libraries and are then provided as Elasticsearch plugins. Elasticsearch is a well-known search engine API based on Apache Lucene. With our plugins we enable search engine developers who wish to ensure fair search results of different styles to easily integrate DELTR and FA*IR into their existing Elasticsearch environment.

Effects of Ocean Circulation on Ocean Anthropogenic Carbon Uptake

description: The ocean is the only cumulative sink of atmospheric CO2. It has absorbed approximately 40% of the CO2 from fossil fuel burning and cement production, lowering atmospheric CO2 and limiting climate change. Here we will examine the regional and global mechanisms controlling the evolution of ocean uptake of this additional carbon from human activities (anthropogenic carbon, Cant) using ocean models and observations. Cant is rapidly injected into the deep ocean, sequestering it from the atmosphere for centuries. It is currently uncertain whether any of this sequestered Cant was absorbed from the atmosphere in the subpolar North Atlantic. Here we present evidence that the upper limb of the ocean’s overturning circulation supplies the subpolar North Atlantic with capacity to absorb Cant from the atmosphere. Using a coupled ocean model, we find that surface freshening of the subpolar North Atlantic reduces the volume available for Cant storage. We also investigate whether global ocean Cant uptake is reduced due to changing ocean circulation, this time across multiple emission scenarios, including scenarios with aggressive emission mitigation. Though it is clear that emission mitigation will reduce the magnitude of the ocean carbon sink, the mechanisms governing the decline in uptake have not been studied in detail. We find that the ocean sink becomes less efficient due to kinematic effects wherein Cant escapes from the surface ocean as atmospheric CO2 plateaus and then declines. In emission scenarios ranging from high to low emissions, projected changes in global Cant uptake due to ocean circulation are small. This is in contrast with the subpolar North Atlantic, where future circulation change plays a important role in the declining Cant uptake.
Effects of Implicit and Explicit Focus on Form on L2 Acquisition of the English Passive

description: Learning a second language (L2) is essential in today’s globalized world. However, learners generally have low sensitivity to grammar, as L2 acquisition proceeds largely through functions. Thus, pedagogical assistance appears to be necessary to trigger learners’ attention to L2 grammar, but research shows no consensus on which type of instruction best promotes it. Moreover, few empirical studies have examined 'acquisition' of target constructions, which entails mappings between form, meaning, and function. To address this gap, the present study investigated the effects of implicit and explicit instruction on L2 acquisition of the English passive. The passive was chosen as the target construction due to the intricate mappings between form, meaning, and function encompassed in it. The study employed an experimental design including a pretest, immediate posttest, and delayed posttest, with five treatment sessions between the pretest and posttests. Participants were 99 Korean English-as-a-foreign-language (EFL) learners, randomly assigned to two experimental groups that received implicit or explicit instruction, respectively, or a control group. Implicit instruction comprised typographically enhanced passive constructions to increase perceptual saliency; explicit instruction comprised a grammar activity to raise the participants’ consciousness about the passive construction. Five measurement tasks were employed to examine any changes in the participants’ knowledge of, and ability to use, the passive: a grammaticality judgment task (GJT), a sentence pair task, a closed discourse completion task (DCT), and spoken and written production tasks. Results from quantitative and qualitative analyses of the data yielded three main findings. First, implicit instruction had a more significant, beneficial effect than explicit instruction on the overall mappings between the form, meaning, and function of the passive. Second, the difference appeared to be more salient for meaning and function, whereas both types of instruction had almost equal benefits for form; yet, the production tasks seemed to exhibit a greater score decrease as for meaning and function over time in both treatment conditions. Finally, each type of instruction had similar effects on the performance of high- and low-level learners. Overall, these findings suggest that both types of instruction are beneficial for L2 acquisition but implicit instruction is more effective than explicit instruction.

description: We provide a systematic way to design computable bilinear forms which, on the class of subspaces $W^* \subseteq \mathcal{V}'$ that can be obtained by duality from a given finite dimensional subspace $W$ of an Hilbert space $\mathcal{V}$, are spectrally equivalent to the scalar product of $\mathcal{V}'$. Such a bilinear form can be used to build a stabilized discretization algorithm for the solution of an abstract saddle point problem allowing to decouple, in the choice of the discretization spaces, the requirements related to the approximation from the inf-sup compatibility condition, which, as we show, can not be completely avoided.

description: This study investigated the effect of instructional videos and real-life activities on the mathematical achievement and attitude of developmental students. The study also investigated the attitude of developmental students towards learning mathematics through instructional videos and real-life activities. The study was conducted at an urban community college with transitional mathematics classes. The four mathematics classes in the study received various combinations of real-life activities, instructional videos, and traditional teaching while studying basic concepts such as decimal place value, percentages, and fractions. Pre-and post-tests were conducted to measure student achievement. Attitude scales, surveys, and interviews were used to measure attitude changes. Results showed that, overall, the mathematics achievement of the classes receiving consistent exposure to videos and real-life activities was greater than classes receiving only some of the special instructional treatments.  Students interviewed believed that instructional videos and real-life activities improved their understanding of the mathematical concepts involved in the study.

description: I tested the effects of mastery of an advanced auditory match-to-sample (MTS) instruction on the emission of full echoic responses, and the emergence of advanced listener literacy and speaker-as-own-listener cusps. In two experiments, an advanced auditory MTS instruction was implemented, in which the auditory MTS FlashÂ® instructional program displayed a computer screen containing one button at the top center of the screen and two buttons below it in the bottom corners of the screen. The top button produced the sample word or phrase, and the two buttons located below produced the exemplar and non-exemplar word or phrase. In the advanced auditory match-to-sample instruction, the participant mastered MTS for words or phrases. In Experiment 1, a counterbalanced delayed multiple probe across participants design was implemented to test the effects of mastery of an advanced auditory MTS instruction on the emergence of advanced listener literacy and Naming, and the emission of full echoic responses. In Experiment 2, a time lagged multiple probe across participants design was implemented to test the effects of mastery of the advanced auditory MTS instruction on the emergence of advanced listener literacy and speaker-as-own-listener cusps (i.e., Naming, say-do correspondence, and self-talk). In addition, Experiment 2 investigated the potential sources of the emergence of advanced listener literacy and speaker-as-own-listener cusps using the probe procedure to identify the degree of conditioned reinforcement for voices. Full echoic responses across all participants significantly improved as a function of the advanced auditory MTS instruction. In Experiment 1, two out of four participants achieved full Naming. In Experiment 2, one out of three participants achieved full Naming. Two participants' self-talk and say-do correspondences significantly increased. Mastery of the protocol also resulted in increased reinforcement for choosing to listen to recorded speech.

description: We discuss fluctuations in the cosmic microwave background (CMB) polarization due to scattering from reionized gas at low redshifts. Polarization is produced by re-scattering of the primordial temperature anisotropy quadrupole and of the kinematic quadrupole that arises from gas motion transverse to the line of sight. We show that both effects produce equal E- and B-parity polarization, and are, in general, several orders of magnitude below the dominant polarization contributions at the last scattering surface to E-modes or the gravitational-lensing contribution to B-modes at intermediate redshifts. These effects are also several orders of magnitude below the B polarization due to lensing even after subtraction with higher-order correlations, and are thus too small to constitute a background for searches for the polarization signature of inflationary gravitational waves.

description: Relief sculpture can be understood as a form in two and a half dimensions, between drawing or painting and sculpture. Relief is also a renewed area of artistic practice, long in decline and marginalized in the 20th Century. It engages with the archaic and the physical and as such is counterpoint to the proliferation of disembodied digital images in contemporary culture. Relief is an art form well suited to re-examining our past from under the shadow of sculpture and painting, not least because it is characterised by ambiguity and dualism and the compatibility of its formal character with themes of conflict and antiquity. This paper discusses the persistence and value of relief sculpture in the 21st Century and analyses the historical dualities of relief and how these dualities resonate in contemporary art. I argue that the scattered presence of relief sculpture in contemporary art no longer designates a strict formal discipline but rather expresses both disjecta membra (fracturing) and a transitional zone in visual arts. Contemporary relief is analysed through the work of artists who have explored dualities within this transitional space: works by Thomas Houseago, Anselm Kiefer, William Kentridge and Matthew Monahan, and through key works from my own studio research, including publically sited works from 2015 to 2018. This paper explores how the transitional zone of contemporary relief echoes the duality inherent in historical (classical) relief. It examines this zone with the superimposition of dualities that include the physical and the image, the archaic and the contemporary. Relief is characterized by dialectics, and the coexistence, reconciliation or synthesis of opposites. It is a manifestation of Edward Soja’s thirdspace (1996) —a shared response or methexis synthesizing history with sensorial and conceptual (or physical and imaginary) space. The research draws from Theodor Adorno’s Aesthetic Theory (1970) and his observations and historical perspective across art forms, arguing that the nature and fate of genres inform understandings of relief sculpture in contemporary art. Perspectives of time and space as described in Jacques Ranciere’s episodic approach to history are complemented by Henri Lefebvre’s and Edward Soja’s subsequent analysis of space. Other philosophers and historians referenced include Walter Pater (1839 to 1894) and his biographer Lene Ostermark-Johansen who form a part of the historical perspective on relief and its position in art. Adolph von Hildebrandt (1847-1921) and Rosalind Krauss assist in comparing relief before and after cubism, which I argue is critical in understanding relief’s renewal through its revised approach to materials coupled to spatial enquiry.
Towards a semiclassical understanding of chaotic single- and many-particle quantum dynamics at post-Heisenberg time scales

description: Despite considerable progress during the last decades in devising a semiclassical theory for classically chaotic quantum systems a quantitative semiclassical understanding of their dynamics at late times (beyond the so-called Heisenberg time $T_H$) is still missing. This challenge, corresponding to resolving spectral structures on energy scales below the mean level spacing, is intimately related to the quest for semiclassically restoring quantum unitarity, which is reflected in real-valued spectral determinants. Guided through insights for quantum graphs we devise a periodic-orbit resummation procedure for quantum chaotic systems invoking periodic-orbit self encounters as the structuring element of a hierarchical phase space dynamics. We propose a way to purely semiclassically construct real spectral determinants based on two major underlying mechanisms: (i) Complementary contributions to the spectral determinant from regrouped pseudo orbits of duration $T < T_H$ and $T_H-T$ are complex conjugate to each other. (ii) Contributions from long periodic orbits involving multiple traversals along shorter orbits cancel out. We furthermore discuss implications for interacting $N$-particle quantum systems with a chaotic classical large-$N$ limit that have recently attracted interest in the context of many-body quantum chaos.
INFLUENCE OF FORMATION TEMPERATURE AND INHIBITOR CONCENTRATION ON THE DISSOCIATION TEMPERATURE FOR HYDRATES FORMED WITH POLY VINYL CAPROLACTAM

description: Inhibitor containing systems were investigated for hydrate structures I and II. The kinetic inhibitor PVCap was added to the water phase for each hydrate structure. Dissociation temperatures were determined for various formation temperatures and PVCap concentrations. Obtained dissociation temperatures were compared with corresponding values calculated with CSMHYD. Differences between experimental and calculated values were compared for various formation temperatures and inhibitor concentrations. Comparison revealed that these parameters (formation temperature and concentration) had an effect on the dissociation temperature. Dissociation temperatures for hydrates formed at low degrees of subcooling were higher than for hydrates formed at large subcooling. The effect depended on the system pressure; apparently decreasing or vanishing with increasing pressure. Furthermore, the temperature of dissociation increased with the inhibitor dose.

description: It is conventionally argued that Dark Matter (DM) has a non-baryonic nature, but if we assume that DM was frozen out before primordial nucleosynthesis and could not significantly impact primordial abundances this argument may be evaded. Then a hypothetical $SU(3)$ flavor-singlet, highly symmetric, deeply bound neutral scalar hexaquark $\mathrm{S}=uuddss$, which due to its features has escaped from experimental detection so far, may be considered as a candidate for a baryonic DM. In the present work we calculate the mass and coupling constant of the scalar six-quark particle $\mathrm{S}$ by means of the QCD sum rule method. Our predictions for its mass are $ m_{S}=1180_{-26}^{+40}~\mathrm{MeV}$ ($m_s=95~\mathrm{MeV}$) and $ \widetilde {m}_{S}=1239_{-28}^{+42}~\mathrm{MeV}$ ($m_s=128~\mathrm{MeV}$). Although these values of mass would produce thermally the cosmological DM abundance, existence of this state may contradict to stability of the oxygen nuclei, which requires further thorough analysis.

description: We prove the existence of perturbations for the PU(2) monopole equations, yielding transversality on the complement of the anti-self-dual or reducible solutions, and the existence of an Uhlenbeck compactification for the moduli space of solutions to these perturbed PU(2) monopole equations. In December 1994, V. Pidstrigach and A. Tyurin and then others proposed a method to prove Witten's conjecture concerning the relation between the Donaldson and Seiberg-Witten invariants of smooth four-manifolds. Their proposal uses a moduli space of solutions to the PU(2) monopole equations, which are a natural generalization of the U(1) monopole equations of Seiberg and Witten and the equation for anti-self-dual SO(3) connections, to construct a cobordism between links of compact moduli spaces of U(1) monopoles of Seiberg-Witten type and the moduli space of anti-self-dual connections, which appear as singularities in this larger moduli space. A basic requirement of this cobordism technique is the existence of an Uhlenbeck compactification for the moduli space of PU(2) monopoles and of generic-parameter transversality results for all the moduli spaces of PU(2) monopoles which appear in this compactification, on the complement of the anti-self-dual and U(1) solutions.

description: The Gutzwiller semiclassical trace formula links the eigenvalues of the Scrodinger operator ^H with the closed orbits of the corresponding classical mechanical system, associated with the Hamiltonian H, when the Planck constant is small ("semiclassical regime"). Gutzwiller gave a heuristic proof, using the Feynman integral representation for the propagator of ^H. Later on mathematicians gave rigorous proofs of this trace formula, under different settings, using the theory of Fourier Integral Operators and Lagrangian manifolds. Here we want to show how the use of coherent states (or gaussian beams) allows us to give a simple and direct proof.
