description: Developing text mining approaches to mine aspects from customer reviews has been well-studied due to its importance in understanding customer needs and product attributes. In contrast, it remains unclear how to predict the future emerging aspects of a new product that currently has little review information. This task, which we named product aspect forecasting, is critical for recommending new products, but also challenging because of the missing reviews. Here, we propose ForeSeer, a novel textual mining and product embedding approach progressively trained on temporal product graphs for this novel product aspect forecasting task. ForeSeer transfers reviews from similar products on a large product graph and exploits these reviews to predict aspects that might emerge in future reviews. A key novelty of our method is to jointly provide review, product, and aspect embeddings that are both time-sensitive and less affected by extremely imbalanced aspect frequencies. We evaluated ForeSeer on a real-world product review system containing 11,536,382 reviews and 11,000 products over 3 years. We observe that ForeSeer substantially outperformed existing approaches with at least 49.1\% AUPRC improvement under the real setting where aspect associations are not given. ForeSeer further improves future link prediction on the product graph and the review aspect association prediction. Collectively, Foreseer offers a novel framework for review forecasting by effectively integrating review text, product network, and temporal information, opening up new avenues for online shopping recommendation and e-commerce applications.

description: The experimental achievements and the results obtained so far with the LPCTrap device installed at GANIL are presented. The apparatus is dedicated to the study of the weak interaction at low energy by means of precise measurements of the BETA-NU angular correlation parameter in nuclear BETA decays. So far, the data collected with three isotopes have enabled to determine, for the first time, the charge state distributions of the recoiling ions, induced by shakeoff process. The analysis is presently refined to deduce the correlation parameters, with the potential of improving both the constraint deduced at low energy on exotic tensor currents (6He1+) and the precision on the V u d element of the quark-mixing matrix (35Ar1+ and 19Ne1+) deduced from the mirror transitions dataset.

description: Rapid technological developments have brought new challenges for the protection of personal data. The right to be forgotten as an element of personal data protection has been debated hotly and controversially for the past few years, especially in Europe. The scale of data sharing and collecting has made personal information publicly and globally available, therefore it is necessary to provide a legal mechanism to persons to remove their personal data from online databases.This thesis seeks to address how important the right to be forgotten will be as a new human right to protect personal data information in the digital age. The right to be forgotten needs better definition to avoid negative consequences since it is not very clear yet. Individuals should have the right to control over their personal information and remove it effectively after a certain time elapsed. Among the development of this right, there is an emerging dispute between European countries and United States, it is discussed in conflict with the right to freedom of expression. In such an information age, the criticism of the right to be forgotten also focus on internet environment in particular. Hence it is a urgent problem that how to implement the right to be forgotten in practice, both legal framework and technical measures should be taken into consideration. Furthermore, in order to improve its efficient function in society and create a more friendly online environment, we need to find sufficient and possible methods both from legal view and technical view to balance the public interests and personal privacy on the application of the right to be forgotten.

description: We calculate the joint distribution $P(S,Q)$ of the scattering matrix $S$ and time-delay matrix $Q=-i\hbar S^\dagger dS/dE$ of a chaotic quantum dot coupled by point contacts to metal electrodes. While $S$ and $Q$ are statistically independent for ballistic coupling, they become correlated for tunnel coupling. We relate the ensemble averages of $Q$ and $S$ and thereby obtain the average density of states at the Fermi level. We apply this to a calculation of the effect of a tunnel barrier on the Majorana resonance in a topological superconductor. We find that the presence of a Majorana bound state is hidden in the density of states and in the thermal conductance if even a single scattering channel has unit tunnel probability. The electrical conductance remains sensitive to the appearance of a Majorana bound state, and we calculate the variation of the average conductance through a topological phase transition.

Microbial soil carbon sequestration pathways

description: Microbial sequestration of Carbon in soil can be compared to a microbial carnival. Each microbe have a definite role to play to give shape to the entire event. Bacteria & fungi are the major players, constituting over 90% of soil microbial biomass although protists & other small eukaryotes also play a pivotal role. Soil microbes directly sequesters C by assimilating above ground plant C inputs, plant litter & associated leachates (e.g. dissolved organic carbon) for growth & release C as Extracellular Polymeric Substances (EPS) & CO2 - the phenomenon is known as microbial carbon use efficiency. The below ground C inputs sources includes rhizodeposition, root litter & exudates which are further broken down by soil microbes, microarthropods & nematodes to finally form Dissolved Organic Matter (DOM), Fine & Coarse Particulate Organic Matter (FPOM & CPOM) and Mineral Associated Organic Matter (MAOM). All these gradually contributes together to soil labile C pool & stable C pool. POMs have lifetime of 1-50 yrs (quick cycling) whereas for MAOMs it is 10-1000 years (slow cycling).
 EPS, root exudates, hyphal exudates, fungal mycelia, Arbuscular Mycorrhizal Fungi (AMF) hyphae, glycoproteins acts as adhesive which along with soil microbiome, DOM, FPOM, CPOM & MAOM contributes towards soil recalcitrant C pools formation (including soil macroaggregates) by Microbial Carbon Pump (MCP). MCP transfers labile organic matter into recalcitrant organic matter via microbial activity causing long-term C storage.
 Microbial biomass & necromass, soil aggregate stability & soil C sequestration are also interrelated. The synthesis & assimilation of plant-derived C materials in the microbial biomass & necromass accounts for between 50-80% of stable Soil Organic Carbon (SOC). Better stability of soil aggregates is imperative for higher stabilized C stocks. It is facilitated by plant leaf or root litter having phenols & lignin & also by certain microbes enhancing soil aggregation, thus protecting SOC from decomposition & promoting C sequestration. Again, soil microbial turnover (i.e. death & necromass formation) & necromass reuse through recycling & destabilization are climate sensitive & ecosystem specific. Further, necromass generation may be a rate-limiting step for stabilization of soil C. Lastly, fungal to bacterial ratio is pivotal towards the soil C flux. A fungal-dominated soil system (e.g. forest) have higher amount of C sequestered in soil.

description: Mitral regurgitation (MR) is a heart valve disease with potentially fatal consequences that can only be forestalled through timely diagnosis and treatment. Traditional diagnosis methods are expensive, labor-intensive and require clinical expertise, posing a barrier to screening for MR. To overcome this impediment, we propose a new semi-supervised model for MR classification called CUSSP. CUSSP operates on cardiac imaging slices of the 4-chamber view of the heart. It uses standard computer vision techniques and contrastive models to learn from large amounts of unlabeled data, in conjunction with specialized classifiers to establish the first ever automated MR classification system. Evaluated on a test set of 179 labeled -- 154 non-MR and 25 MR -- sequences, CUSSP attains an F1 score of 0.69 and a ROC-AUC score of 0.88, setting the first benchmark result for this new task.

title: Evaluation of the physical properties of experimental macromolecular crowding systems
Creators: name: Thrithamara Ranganathan, Venketesh
Publisher: name: Memorial University of Newfounland
Year: 2022

description: Biological cells are crowded environments consisting of both large and small molecules. The macromolecular crowding observed in biological cells is likely very important to the structure and function of a living cell. Since the macromolecules can interact with each other, this makes the system complex and there remain several open questions. In the laboratory, artificial crowder molecules can be used to create experimental model systems that mimic the cellular environment. Artificial crowders such as the polysaccharide, Ficoll, have long been assumed to be compact and colloidal, but a holistic understanding of its structure and dynamics is lacking. This thesis investigates the structure of Ficoll using multiple experimental techniques. We report rheology, small angle neutron scattering, self diffusion and relaxation measurements using nuclear magnetic resonance experiments on two widely used artificial crowder molecules, Ficoll-70 and Ficoll-400. Our results, combining measures of structure, diffusion, relaxation and rheology, show that Ficolls are more polymer like than colloid like. Importantly, we find that the self-diffusion of HDO molecules in the suspension is an efficient probe to evaluate volume occupancy of the suspension under investigation. We then evaluate the physical properties of a protein crowder solution, BSA, and phytoglycogen, a natural plant based dendrimer using the methods developed to evaluate the Ficoll suspension properties. For all crowders, we find that the self diffusion coefficient decreases exponentially with a characteristic concentration of 10-12 wt %. We also observe that the NMR transverse relaxation of the solvent is a sensitive, independent measure of water confinement, which can be correlated with suspension rheology and self diffusion. To summarize, the highlight of this thesis is that structural and dynamical methods that report on macromolecules as well as solvent can provide a more complete view of macromolecular crowding.
Electromagnetic angular momentum of quantized wavepackets in free space

description: A single electromagnetic plane-wave propagating in free space possesses neither spin nor orbital angular momentum. Both types of angular momentum arise from interference between pairs of plane-waves having the same temporal frequency ω but differing k-vectors k_1 and k_2. While it is fairly straightforward to evaluate a wavepacket's spin and orbital angular momenta in the (k,ω) continuum by means of Fourier transformation, obtaining the same results by discretizing the (k,ω) space, then attempting to approach the continuum limit via an infinite enlargement of the spatial volume under consideration, is fraught with danger.

description: Nanoscale inhomogeneities are typical for numerous metallic alloys and crucially important for their practical applications. At the same time, stabilization mechanisms of such a state are poorly understood. We present a general overview of the problem, together with a more detailed discussion of the prototype example, namely, Guinier-Preston zones in Al-based alloys. It is shown that coherent strain due to a misfit between inclusion and host crystal lattices plays a decisive role in the emergence of the inhomogeneous state. We suggest a model explaining formation of ultrathin plates (with the thickness of a few lattice constants) typical for Al-Cu alloys. Discreteness of the array of misfit dislocations and long-ranged elastic interactions between them are the key ingredients of the model. This opens a way to a general understanding of the nature of (meta)stable embedded nanoparticles in practically important systems.

Cession and Retreat: Negotiating Hong Kong's Future, 1979-1984
Creators: name: Cockram, Rebekah

description: In the mid-nineteenth century, Britain acquired Hong Kong from the Qing dynasty in three parts via three separate legal agreements. Unlike the international agreements that ceded Hong Kong Island and the Kowloon Peninsula to the British indefinitely, Britain’s possession of the New Territories had a fixed expiration date of July 1, 1997. As the expiration date of the New Territories Lease approached, British officials responded to investor fears about the future of Hong Kong and determined that they held strong legal and economic arguments to advocate for continued British administration after 1997. By 1984, however, Britain relinquished their sovereign claims to Hong Kong and retreated from the territory. This thesis underscores how Britain’s miscalculations concerning the strength of their legal and economic arguments as well as China’s tough negotiating constraints led Britain to change their policy and eventually cede sovereignty of territory otherwise guaranteed to them under international law. Moreover, it evaluates how China undermined Britain’s attempts to advocate for the Hong Kong people in a direct way and evaluates the relative success of the negotiated outcome for Britain.

description: Economic global competition is seriously threatening labour standards worldwide, and especially in most developing countries, where governments are not interested in improving core labour standards in order to take a competitive advantage and to attract foreign investments. Developed countries, in their turn, try to fight back their loss of competitiveness by removing some labour rights gained by employees in the past decades. Such a dynamic inevitably produces a race to the bottom, which can only be stopped by linking international trade and labour standards. Nonetheless, attempts to reach such a linkage within the World Trade Organisation have been unsuccessful. As a consequence, the European Union is trying to link trade and labour standards by including social clauses in unilateral trade preferences as well as in bilateral and regional trade agreements with developing countries. This research will examine the EU’s trade policy with regard to labour standards in developing countries, in particular the failed attempts to include labour standards in the multilateral trading system, and the EU unilateral preferential regimes and bilateral trade agreements, with a special attention to the recent free trade agreement with Colombia and Peru. The analysis of this agreement is particularly interesting since Peru and Colombia are characterised by widespread violations of labour rights, and it will help us to understand if the policy of the EU on labour standards in developing countries is really aimed at improving the conditions of local workers and, if so, if it is really effective.
Some cryptographic properties of Boolean functions

Publisher: name: Universit� degli studi di Trento

description: We investigate some cryptographic properties of Boolean functions. Some of the properties we are going to consider include weight, balancedness, nonlinearity and resiliency. Mainly, we study how the properties of a Boolean function can be related to the properties of some other functions in a lower dimension. We utilize these relations to construct balanced and resilient functions. Another aspect which we consider is the set of linear structures of Boolean functions. Our interest is in construction of balanced functions which have a trivial set of linear structures. It is well-known that block ciphers may suffer from two main attacks, namely, differential attacks and linear attacks. APN functions are known to provide the best resistance against differential attacks. We look at some properties of APN functions in even dimension. We study the linear structures of their components. We show that there must be at least a component whose set of linear structures is trivial. In particular, we determine the possible size of the set of linear structures for any component of an APN permutation. Based on the sizes of the sets of linear structures for the components, we establish a simple characterization of quadratic APN functions, and this knowledge is useful in proving some results on a general form for the number of bent components. We further consider counting bent components in any quadratic power functions. Based on the behaviour of second order derivatives, we derive some quantities which are used for characterization of quadratic and cubic APN functions. We show that these quantities can also be used to characterize quadratic and cubic Bent functions. Furthermore, we show that these derived quantities can be linked to the size of the set of linear structures for any quadratic and cubic partially-bent functions.

The discrete equations are solved using a matrix-free preconditioned conjugate gradient algorithm. An additive Schwartz two-scale preconditioner is employed that allows h-independence convergence. An extensible multi-threading programming API is used as a common kernel language that allows runtime selection of different computing devices (GPU and CPU) and different threading interfaces (CUDA, OpenCL and OpenMP). Performance tests demonstrate that problems with over 50 million degrees of freedom can be solved in a few seconds on an off-the-shelf GPU.

The donor ‘human rights’ schizophrenia : aid cuts for human rights violations or the high costs of having good intentions

Subjects: conditionality

description: Second semester University: University of Vienna
description: This thesis is devoted to challenging the idea that human rights violations should be a reason to cut foreign aid. While the issue is regarded as a matter of individual donor policy, if any, some provisional theoretical orientation for reconsidering and reframing such a practice is discussed here, along with a call for a more thorough and observant approach to human rights both in policy formulation and associated decision-making. The aforementioned stance is formed in relation to two factors: donors’ general attitude towards human rights in their foreign aid policies, and general objections that can be made to use of conditionality in aid. A closer focus on human rights conditionality reveals inconsistencies related to recipient’s ownership in development, donor’s assumption of a judicial role, and the difficulties associated with its implementation which lead to it lowered effectiveness. Finally, the mere hypothesis of feasibility of conditionality leveraging human rights improvements is put to a test, as it seems to be unable to address the complexity of situation at stake.
Language contact as innovation: the case of Cimbrian
Creators: name: Turolla, Claudia
Publisher: name: Universit� degli studi di Trento
Year: 2019

description: Traditionally, language contact studies have dealt with grammatical interference between two languages. Clearly, the case of Cimbrian is unique in that its linguistic system results from contact with two different languages: German, which belongs to the same family that Cimbrian is commonly considered to belong to (Germanic) and Italian, which belongs to a different language family (Romance). For this reason, this dissertation has two main aims: First and foremost, it aims to provide the first theoretical account for three relevant morpho-syntactic features of Cimbrian: adjectival ordering, participial forms, and auxiliary selection. These three case studies were purposefully chosen as being representative of the impact the two source languages had on the receiving language. Second, by looking at the three aforementioned cases, it ultimately aims to lay ground- work for further research on theoretical approaches to language variation and innovation via language contact.
The Happy Heels Study: Testing Whether Positive Exercises Improve Mental Health, Happiness and Academics in First-Year Students

description: College students face increasing amounts of stress related to navigating and thriving at universities. With increasing levels of anxiety, depressive symptoms and the strain placed on college counseling and psychological services, new creative ways are needed to assist students with their mental health and well-being. Three Good Things and a variant that focuses on social connection, are two exercises shown to improve mental and physical well-being, as well as reduce loneliness. 160 UNC first-year and transfer students participated in a two-week intervention where they performed Three Good Things (3GT) or an adapted Positivity Resonance exercise (3GT-Social). Results showed that while no significant changes in academic performance or visits to counseling services emerged, students did report significant improvements in loneliness, positivity resonance with strangers and acquaintances, and depressive symptoms, with between-group differences approaching significance at one follow-up time point. The two exercises offer a novel approach to addressing the mental health of many college students while also at little costs to university resources.

For the isotropic integrable deformation and for a semi-simple group $G$ we compute the anomalous dimensions using two different methods. In the first we use the all-loop effective action and in the second we employ perturbation theory along with the Callan-Symanzik equation and in conjunction with a duality-type symmetry shared by these models. Furthermore, using CFT techniques we compute the all-loop anomalous dimensions of bilinear currents for the isotropic deformation case and a general $G$. Finally we work out the cases of anisotropic $SU(2)$ and the two coupling, corresponding to the symmetric coset $G/H$ and a subgroup $H$, splitting of a group $G$.

NONLINEAR WAVES EXCITATION AND INTERACTION IN PURE ELECTRON PLASMAS
Creators: name: PANZERI, NICOLA
Publisher: name: Universit� degli Studi di Milano
Year: 2021

description: Nonneutral plasmas are excellent subjects for well controlled studies on basic physics problems and industrial research over a wide range of parameters. For the long-time confinement, merger and recombination of antimatter, the method of choice is some variant of the Penning-Malmberg trap, and many of the techniques for the manipulation of charged particles, such as cooling, compression, transfer, and ultimately a stable confinement in a quiescent state, are based on methods first developed by the nonneutral plasma community using electron plasmas. Another fascinating properties of nonneutral plasmas is the fluid analogy: in a cold, magnetized, nonneutral plasma, the 2D transverse dynamics equations are isomorphic to the Euler equations for an ideal 2D fluid. Hence, a pure electron plasma in a Penning-Malmberg trap evolves as an inviscid, incompressible bidimensional fluid. The study and control of the various waves and instabilities is of great interest in physics, and it is often intertwined with non-linearity and turbulence. Experiments aimed at unveiling hidden dependencies between parameters or improve the control over non-equilibrium, unstable configurations can lead to the discover of new phenomena, and a more thorough understanding of basic plasma physics, like the excitation and interaction of different plasma modes in pure electron plasmas, is likely to be a useful tool for a range of applications. In this thesis work, we present the results of the experiments made on two different Penning-Malmberg traps on the excitation and interaction of nonlinear waves in pure electron plasmas. On the Eltrap device, located at the University of Milan, Italy, we perform experiments on the excitation and control of high order diocotron modes via the rotating electric field technique. On the CamV device, located at the University of California, San Diego, we investigate the newly discovered phenomenon of TG waves splitting due to the interaction with a diocotron mode.
"I'm kind of woke": a teacher action research study of a social justice literature course in a privileged community
Creators: name: Bardes, Angela Susan
Publisher: name: No Publisher Supplied
Year: 2023

description: The many manifestations of social justice education center the experiences of the marginalized and oppressed to create a more democratic society. In recent years, scholars have begun to argue that privileged students, not the marginalized, should be the target of social justice education, advocating for a pedagogy that puts the onus on the privileged to dismantle white supremacy and other systems of oppression. This teacher action research study uses social and cultural capital theory and critical race theory, specifically critical whiteness studies, to analyze the experiences of high school seniors enrolled in a new social justice literature course in a privileged community in northern New Jersey. Using ethnographic and action research methods, including fieldnotes, interviews, student work artifacts, audio of class discussions, personal reflections, and more, this study explores how privileged students and their teacher navigate an English language arts curriculum that deals with social justice issues. The research questions guiding this study were: 1) How do students in a privileged community experience social justice curriculum and pedagogy in their English class? and 2) How does the teacher experience and make sense of teaching a course dealing with social justice issues within the sociopolitical context of a privileged school district? Findings revealed the complex role of whiteness in a class comprised of mostly White and Asian American students; the effects of personalizing social justice issues for privileged students; the importance of planning for students to reflect on and analyze their personal experiences and conceptions of privilege; and how to foster a classroom environment that allows for the discomfort and vulnerability necessary for real social justice learning to occur.

description: The general aim of this work was to study lakes?s benthic communities, particularly Chironomids (Diptera Chironomidae), to select the environmental factors correlated to their diversity and distribution and to provide information about their ecology. A self-organizing map analysis (SOM) was carried out to ordinate sites (samples from 50 Italian lakes) according to macroinvertebrate community composition. Environmental variables were also included in the two dimension maps to highlight which factors are associated with site-taxa distribution (dissolved oxygen and nutrient content were selected). Within species with an indicator role of hypoxia, high nutrient amount, inorganic and organic pollution, the Chironomid Chironomus riparius Meigen 1804 was selected. A first series of experiments were carried out in lab on IV-instar larvae to investigate the role of the respiratory pigment hemoglobin and of the enzyme alcohol dehydrogenase in survive hypoxia and anoxia. A second series of experiments were carried out always on IV-instar larvae to investigate the role of five candidate genes (hsp10, hsp40, hsp70, hsc70 and cyp450) in toxic resistance (Cu and azadirachtin) (Real Time PCR analysis). Overall more information on autoecology of Chironomids was given by this study, and new data on potential biomarkers useful in biomonitoring of lakes.

description: We present results from the first dedicated study in the time domain of the hard X-ray variability behavior of blazars on long timescales based on $\sim$13 years of continuous hard X-ray data in the 14-195 keV band. We use monthly-binned data from the recent 157-month Swift-BAT catalog to characterize the hard X-ray variability of 127 blazars and search for potential differences between the variability of BL Lacertae objects (BL Lacs) and flat-spectrum radio quasars (FSRQs). A significant portion of the blazars in the sample ($\sim$37%) do not show statistically significant hard X-ray variability on monthly timescales, which is deeply at odds with previous studies that show that blazars are highly variable in the X-rays and other energy bands on a wide range of timescales. We also find that, on average, the FSRQs and BL Lacs for which we do detect variability exhibit similar flux variability; this suggests that the variability in these FSRQs is not necessarily driven by variations in the source function of scattered external radiation arriving from extended regions, and that it is instead possibly driven by processes that lead to variations in particle injection. In addition, only five blazars in our sample show significant spectral variability in the long-term light curves. For 3 blazars, we find that a power law that changes slope on monthly timescales is sufficient to characterize the variable hard X-ray spectrum, suggesting that, at least for some bright blazars, the long-term spectra in the hard X-rays may be described in a relatively simple fashion.

Translocation of GPAT4 from the endoplasmic reticulum to the mitochondria may alter efficiency of TAG synthesis in liver cells

description: Synthesis of triacylglycerol (TAG) is critical for the formation of lipoproteins and lipid droplets and is the main constituent of mammalian fat. The rate of TAG synthesis is controlled by the enzyme glycerol-3-phosphate acyltransferase (GPAT). GPAT4, an isoform of GPAT, is found predominantly in the endoplasmic reticulum (ER), while GPAT1 is found in the mitochondria. Although GPAT4 and GPAT1 both produce lysophosphatidic acid (LPA), it is not known whether the output of phospholipids whose synthesis was initiated in the outer-mitochondrial membrane (OMM) differ from those that are initiated in the ER. It was hypothesized that GPAT4 and GPAT1 have non-interchangeable outputs within the cell and that the introduction of GPAT4 to the mitochondria would not affect TAG output. To determine if there was a difference between the outputs of GPAT 1 and GPAT4, primary liver cells were infected with adenovirus to express GPAT4 on the mitochondria (Ad-Tom20-GPAT4, “mtGPAT4-FLAG”). We measured GPAT enzyme activity in total particulate prepared from primary mouse hepatocytes and total particulate prepared from a mouse hepatoma cell line, Hepa 1-6, infected with these adenoviruses. The introduction of mtGPAT4-FLAG had an inconclusive change in activity in primary mouse hepatocytes while it had a doubling effect on enzyme specific activity in Hepa 1-6 cells as compared to the GFP control adenovirus (Ad-T20-GFP-BirA, “GFP control adenovirus”). These results indicate conflicting information about the introduction of mtGPAT4-FLAG. Future experiments within Hepa 1-6 cells or possibly whole animal models should be considered for further analysis on the effect of incorporating mtGPAT4-FLAG.  Understanding what affects the efficiency of TAG synthesis is important for providing a better understanding of diseases that are influenced by TAG production and maintenance, such as diabetes mellitus, lipodystrophy, and heart disease.

description: The thesis presents international housing rights, with a focus on Europe. It shows their development of housing rights standards and analysis the jurisprudence related to them. The end of this part (Chapter 2) consists in a proposal concerning the future development of housing rights: it is argued that more individual enforceability is needed and that they could have a preventive function to protect persons in vulnerable situations from homelessness. Policies on homelessness within the European Union’s social policy are presented with an overview over the development of the EU’s social policy and the growing importance the topic of homelessness plays therein (Chapter 3). It is critically examined if the EU policy on homelessness is able to deliver progress. Further, the role of housing rights within the EU social policy is analysed. Concluding that they do not play an important role yet, it is argued that the inclusion of housing rights to homelessness policies would improve their quality. Finally, the need for an EU-wide policy on homelessness based on housing rights is argued (Chapter 4). Several possibilities are shown on how to include these rights to such policy and on which role they could play therein.
title: Radiation effects in pyrochlore-based glass-ceramics

description: Safe and reliable management of nuclear waste is one of the key components if energy from nuclear is to become a primary energy source. The current strategy involves immobilizing high-level nuclear waste from spent nuclear fuel in a glass or ceramic wasteform. Nuclear wasteforms used to immobilize the actinides must remain stable for long geological timescales. Pyrochlore-based glass-ceramics have the potential to be the novel nuclear wasteforms. In order to evaluate the performance of glass-ceramic wasteforms during long-term storage and compare with pure ceramics wasteforms, in this thesis, radiation effects from α-decay events have been investigated in Gd2Ti2O7 and Y2Ti2O7 glass-ceramic composites using accelerated ion beams. Separate effect of He accumulation was studied in Gd2Ti2O7 glass-ceramics, showing that the helium bubbles with an average bubble size of 1.2 nm were formed within the ceramic ma trix at 1.1 × 1017 He/cm2 (15 at.%). While no helium bubbles were observed in glass phase due to their higher diffusion coefficient. Besides, helium bubbles preferred to nucleate near glass-ceramic interfaces and accumulate along ceramic grain boundaries. Separate effect of α-recoil damage was also studied in Y2Ti2O7 glass-ceramics, showing that the fully amorphization of pyrochlores occurred at 5 × 1014 Au/cm2, indicating Y2Ti2O7 glass-ceramics retain comparable radiation tolerance as Y2Ti2O7 ceramics. The phase transformation to the defect-fluorite structure was observed at the interface between pristine and irradiated regions. In relevant geological environments, the waste forms will experience modifications due to synergistic effects produced by α-recoil’s displacive damage and He accumulation. Combined effects of α-recoil damage and He accumulation were studied in pre-damaged Y2Ti2O7 glass-ceramics, showing that the accumulation of He can lead to the nucleation of helium bubbles within the amorphous Y2Ti2O7 ceramic phase at a critical concentration of 3.4 at.%, corresponding to 45,000 years of 20 wt.% 239Pu loading. Hence, amorphization caused by α-recoil damage may occur before helium bubble nucleation. To the best of our knowledge, the works related to the radiation damage in glass-ceramics are very limited, and this being the first one to present radiation damage and He accumulation in pyrochlore-based glass-ceramics.

description: The exclusive semileptonic decay $B \rightarrow π\ell ν$ is a key process for the determination of the Cabibbo-Kobayashi-Maskawa matrix element $V_{ub}$ from the comparison of experimental rates as a function of $q^2$ with theoretically determined form factors. The sensitivity of the form factors to the $u/d$ quark mass has meant significant systematic uncertainties in lattice QCD calculations at unphysically heavy pion masses. Here we give the first lattice QCD calculations of this process for u/d quark masses going down to their physical values, calculating the $f_0$ form factor at zero recoil to 3\%. We are able to resolve a long-standing controversy by showing that the soft-pion theorem result $f_0(q^2_{max}) = f_B/f_π$ does hold as $m_π \rightarrow 0$. We use the Highly Improved Staggered Quark formalism for the light quarks and show that staggered chiral perturbation theory for the $m_π$ dependence is almost identical to continuum chiral perturbation theory for $f_0$, $f_B$ and $f_π$. We also give results for other processes such as $B_s \rightarrow K \ell ν$.
