description: In-plane microwave penetration depth $λ_{ab}$ and quaiparticle conductivity at 28 GHz are measured in underdoped single crystals of the Fe-based superconductor PrFeAsO$_{1-y}$ ($T_c\approx 35$ K) by using a sensitive superconducting cavity resonator. $λ_{ab}(T)$ shows flat dependence at low temperatures, which is incompatible with the presence of nodes in the superconducting gap $Δ({\bf k})$. The temperature dependence of the superfluid density demonstrates that the gap is non-zero ($Δ/k_BT_c\gtrsim 1.6$) all over the Fermi surface. The microwave conductivity below $T_c$ exhibits an enhancement larger than the coherence peak, reminiscent of high-$T_c$ cuprate superconductors.

description: We develop a kinetic theory for strongly correlated disordered one-dimensional electron systems out of equilibrium, within the Luttinger liquid model. In the absence of inhomogeneities, the model exhibits no relaxation to equilibrium. We derive kinetic equations for electron and plasmon distribution functions in the presence of impurities and calculate the equilibration rate $γ_E$. Remarkably, for not too low temperature and bias voltage, $γ_E$ is given by the elastic backscattering rate, independent of the strength of electron-electron interaction, temperature, and bias.

Assessment of milk quality along the dairy value chain in Mbeya and Songwe region, southern highlands of Tanzania
Creators: name: Wilson, Wilson Charles
Publisher: name: Zenodo
Year: 2017
Subjects: Dairy value chain, Milk quality, Net-Map

description: Abstract
 Currently, the demand for milk products in Tanzania is higher than the domestic production and supply. Milk quality management along the dairy value chain is important to reduce microbial contamination that may cause milk-borne diseases to humans. The main objective of this study was to assess the existing dairy value chain and evaluate different factors affecting milk quality in urban (UR), peri-urban (PU) and rural (RU) locations in Mbeya and Songwe region in the southern highlands of Tanzania. Data were gathered through a semi-structured questionnaire-based survey with 98 dairy farmers, and focus group discussions with a group of seven dairy farmers in each location. Also, a checklist of questions was used to collect information from four identified milk collection centres and traders. Furthermore, a participatory rural appraisal Net-Map approach with 15 actors in the dairy sector was done to assess the existing dairy value chain and analyse the linkages, power in decision making and gaps in the dairy value chain. The quantitative and qualitative data were analysed using Statistical Package for the Social Sciences (SPSS) version 23 and Visualizer 2.1 software’s, respectively. Dairy cattle are mainly kept under a zero-grazing system in all locations, mainly composed of Friesian crosses and non-descript crossbreeds. The informal dairy value chain dominates the UR location while the formal value chain slowly gaining ground in the PU and RU locations (p<0.05). Most farmers in the PU and RU locations are involved in farmer groups/cooperatives that influence the formal dairy value chain in these locations. The Net-Map results indicate that there are weak government extension services, and the government have less involvement in the functioning of the dairy value chain. Research is marginalised in the region with little/no feedback to farmers. Milk quality at farm level is constrained by poor hygienic hand-milking practices, low quality feeds, occurrences of diseases and poor dairy cattle housing. Quality management systems should start at the farm level and proper post-harvest handling is required along the dairy value chain to reduce microbial contamination and ensure consumer’s health and safety.

description: We investigate existence and asymptotic completeness of the wave operators for nonlinear Klein-Gordon and Schrödinger equations with a defocusing exponential nonlinearity in two space dimensions. A certain threshold is defined based on the value of the conserved Hamiltonian, below which the exponential potential energy is dominated by the kinetic energy via a Trudinger-Moser type inequality. We prove that if the energy is below or equal to the critical value, then the solution approaches a free Klein-Gordon solution at the time infinity. The interesting feature in the critical case is that the Strichartz estimate together with Sobolev-type inequalities can not control the nonlinear term uniformly on each time interval, but with constants depending on how much the solution is concentrated. Thus we have to trace concentration of the energy along time, in order to set up favorable nonlinear estimates, and then to implement Bourgain's induction argument. We show the same result for the "subcritical" nonlinear Schrödinger equation.

Return governance

description: The Islamic Republic of Iran hosts the largest population of Afghan refugees worldwide. However, recent years have seen significant dynamics in both inflow and outflow, highlighting the complexities of return migration governance. While estimates vary, with the United Nations High Commissioner for Refugees (UNHCR) suggesting around 4.5 million Afghans in Iran and the Iranian government indicating over 5 million, the International Organization for Migration (IOM) recorded a substantial out-migration of 8.99 million from Afghanistan to Iran between 2021 and 2023, with 7.97 million returns from Iran and Afghanistan recorded during the same period.

Multiple factors drive this migration pattern, including political upheaval post-regime change in August 2021, socio-economic strains exacerbated by disruptions in international aid, and societal norms impacting women's inclusion in education and employment. Notably, the UNHCR reports a spike in daily crossings from Afghanistan to Iran, jumping from 2,000 to 5,000 between August and September 2021.Despite Iran's commitment to international refugee conventions, data on Afghan asylum seekers and recognized refugees seeking protection in Iran remain very limited. Iran's governance of return migration reflects a nuanced response shaped by socio-political dynamics, economic realities, and diplomatic relations with Afghanistan and the broader international community. This underscores the evolving nature of return migration governance and the need for comprehensive approaches to address the diverse challenges and opportunities it presents. This report assesses Iran’s approach to return migration governance, examining the factors that contributed to the development of return migration infrastructure and influenced Iran’s changing return migration diplomacies. Additionally, it sheds light on Afghanistan’s return and reintegration approaches, policy frameworks and legal documents.
Detailed Abundances of Planet-Hosting Open Clusters. The Praesepe (Beehive) Cluster

description: It is not yet fully understood how planet formation affects the properties of host stars, in or out of a cluster; however, abundance trends can help us understand these processes. We present a detailed chemical abundance analysis of six stars in Praesepe, a planet-hosting open cluster. Pr0201 is known to host a close-in (period of 4.4 days) giant planet (mass of 0.54$\rm M_{\rm{J}}$), while the other five cluster members in our sample (Pr0133, Pr0081, Pr0208, Pr0051, and Pr0076) have no detected planets according to RV measurements. Using high-resolution, high signal-to-noise echelle spectra obtained with Keck/HIRES and a novel approach to equivalent width measurements (XSpect-EW), we derived abundances of up to 20 elements spanning a range of condensation temperatures (Tc). We find a mean cluster metallicity of [Fe/H] = +0.21$\pm$0.02 dex, in agreement with most previous determinations. We find most of our elements show a [X/Fe] scatter of $\sim$0.02-0.03 dex and conclude that our stellar sample is chemically homogeneous. The Tc slope for the cluster mean abundances is consistent with zero and none of the stars in our sample exhibit individually a statistically significant Tc slope. Using a planet engulfment model, we find that the planet-host, Pr0201, shows no evidence of significant enrichment in its refractory elements when compared to the cluster mean that would be consistent with a planetary accretion scenario.

description: The $N$-qubit Greenberger-Horne-Zeilinger (GHZ) states are the maximally entangled states of $N$ qubits, which have had many important applications in quantum information processing, such as quantum key distribution and quantum secret sharing. Thus how to distinguish the GHZ states from other quantum states becomes a significant problem. In this work, by presenting a family of the generalized Clauser-Horne-Shimony-Holt (CHSH) inequality, we show that the $N$-qubit GHZ states can be indeed identified by the maximal violations of the generalized CHSH inequality under some specific measurement settings. The generalized CHSH inequality is simple and contains only four correlation functions for any $N$-qubit system, thus has the merit of facilitating experimental verification. Furthermore, we present a quantum phenomenon of robust violations of the generalized CHSH inequality, in which the maximal violation of Bell's inequality can be robust under some specific noises adding to the $N$-qubit GHZ states.

description: Given a ring of ternions $R$, i. e., a ring isomorphic to that of upper triangular $2\times 2$ matrices with entries from an arbitrary commutative field $F$, a complete classification is performed of the vectors from the free left $R$-module $R^{n+1}$, $n \geq 1$, and of the cyclic submodules generated by these vectors. The vectors fall into $5 + |F|$ and the submodules into 6 distinct orbits under the action of the general linear group $\GL_{n+1}(R)$. Particular attention is paid to {\it free} cyclic submodules generated by \emph{non}-unimodular vectors, as these are linked with the lines of $\PG(n,F)$, the $n$-dimensional projective space over $F$. In the finite case, $F$ = $\GF(q)$, explicit formulas are derived for both the total number of non-unimodular free cyclic submodules and the number of such submodules passing through a given vector. These formulas yield a combinatorial approach to the lines and points of $\PG(n,q)$, $n\geq 2$, in terms of vectors and non-unimodular free cyclic submodules of $R^{n+1}$.

description: We revisit the problem of the quarter-filled one-dimensional Kondo lattice model, for which the existence of a dimerized phase and a non-zero charge gap had been reported in Phys. Rev. Lett. \textbf{90}, 247204 (2003). Recently, some objections were raised claiming that the system is neither dimerized nor has a charge gap. In the interest of clarifying this important issue, we show that these objections are based on results obtained under conditions in which the dimer order is artificially suppressed. We use the incontrovertible dimerized phase of the Majumdar-Ghosh point of the $J_{1}-J_{2}$ Heisenberg model as a paradigm with which to illustrate this artificial suppression. Finally, by means of extremely accurate DMRG calculations, we show that the charge gap is indeed non-zero in the dimerized phase.

title: Writing Home: An Exploration of The Writing of Jack and Bet (A Novel) And A Consideration of What the Novel – As A Space and A Practice – Might Offer to Our Understanding of The Concept of Home, And What A Consideration of Home Might Offer to Our Understanding of The Novel.
Creators: name: Butler, Sarah
Publisher: name: The Open University
Year: 2021

description: This creative-critical thesis consists of a novel, Jack and Bet, and a supporting critical commentary. Jack and Bet tells the story of two octogenarians living in Elephant and Castle, South London, as the Heygate Estate (their former home) is demolished. The critical commentary brings together theories from literary criticism, geography, anthropology and urban studies to explore how the practice of writing and the space of the novel intersect with ideas of home.

 Written in the third person, the novel switches between Jack, Bet, and a young Romanian student, Marinela. These voices interweave to tell the story of Jack and Bet's struggle to maintain their independence and stay in their own home as they age; Marinela's attempts to create a new home in a foreign city; and how the friendship between the three unearths long-buried secrets which jeopardise Jack and Bet's marriage and their relationship with their son.

 Beginning with an overview of theories of home and the home-spaces of the novel, the commentary explores home as an active process and a physical site. It considers Jack and Bet, with additional analysis of novels by Ann Patchett and Anne Tyler, in relation to the verbs to leave, to stay, to return and to settle, alongside themes of loss, nostalgia and recuperation, and the idea of writing itself as a home.

 Written at a time of gentrification and rising house prices, Jack and Bet contributes to a growing body of research about home, gentrification and how we inhabit cities. Published just before the first Covid-lockdown of 2020, it is also a pertinent exploration of home and the value of our older population. Together the novel and the commentary argue for a more expansive idea of domestic fiction, and a richer, more interdisciplinary approach to home and the novel.

description: We propose a novel low-complexity lidar gesture recognition system for mobile robot control robust to gesture variation. Our system uses a modular approach, consisting of a pose estimation module and a gesture classifier. Pose estimates are predicted from lidar scans using a Convolutional Neural Network trained using an existing stereo-based pose estimation system. Gesture classification is accomplished using a Long Short-Term Memory network and uses a sequence of estimated body poses as input to predict a gesture. Breaking down the pipeline into two modules reduces the dimensionality of the input, which could be lidar scans, stereo imagery, or any other modality from which body keypoints can be extracted, making our system lightweight and suitable for mobile robot control with limited computing power. The use of lidar contributes to the robustness of the system, allowing it to operate in most outdoor conditions, to be independent of lighting conditions, and for input to be detected 360 degrees around the robot. The lidar-based pose estimator and gesture classifier use data augmentation and automated labeling techniques, requiring a minimal amount of data collection and avoiding the need for manual labeling. We report experimental results for each module of our system and demonstrate its effectiveness by testing it in a real-world robot teleoperation setting.

description: Modellgetriebene Softwareentwicklung erlaubt schnelleres und vereinfachtes Entwickeln von Software durch das Bereitstellen einer höheren Abstraktionsebene als Code. Modellgetriebene Programme generieren Code oft teilweise oder vollständig mithilfe von Modellen. Aus diesem Grund benötigt man ein geeignetes Modell, um modellgetriebene Prozesse verwenden zu können. Das Eclipse Modeling Framework bietet das sogenannte Ecore Metametamodell, welches das Erstellen von Metamodellen ermöglicht, die für modellgetriebene Softwareentwicklung genutzt werden können. Mithilfe des Eclipse Modeling Frameworks ist es möglich, Java Code zu generieren. Dieser generierte Code folgt spezifischen Mustern. Zum Beispiel unterscheidet er für jede Klasse zwischen Schnittstelle und Implementierung. Viele Programme sind auf diese spezifischen Muster angewiesen und können deshalb nur mit Java Code verwendet werden, welcher diese Muster enthält. Das ist üblicherweise Code, der mithilfe eines Ecore Metamodells generiert wurde. In dieser Arbeit stellen wir einen Ansatz für die automatische Integration von Ecore Funktionalität in Java Code vor. Dieser Ansatz ermöglicht die Verwendung von Ecore-abhängigen Programmen mit existierendem Java Code. Um die Integration von Ecore Funktionalität zu ermöglichen, entwickelt diese Arbeit einen Ansatz für die Extraktion von Ecore Metamodellen aus Java Code. In ihrem Zentrum steht eine Abbildung von Elementen des impliziten Java Metamodells auf Elemente des Ecore Metametamodells. Diese Extraktion kann unabhängig von der Integration von Ecore Funktionalität als Reverse Engineering Programm verwendet werden. Wir erbringen einen Nachweis für die Korrektheit unseres Ansatzes, indem wir Ecore Funktionalität in zwei Java Projekte integrieren und auf diese dann eine Modelltransformation anwenden, was zuvor nur auf Code, der aus Ecore Metamodellen generiert wurde, möglich war.

description: We develop a mesoscopic lattice Boltzmann model for liquid-vapor phase transition by handling the microscopic molecular interaction. The short-range molecular interaction is incorporated by recovering an equation of state for dense gases, and the long-range molecular interaction is mimicked by introducing a pairwise interaction force. Double distribution functions are employed, with the density distribution function for the mass and momentum conservation laws and an innovative total kinetic energy distribution function for the energy conservation law. The recovered mesomacroscopic governing equations are fully consistent with kinetic theory, and thermodynamic consistency is naturally satisfied.

description: The Internet of Things (IoT) is the next industrial revolution: we will interact naturally with real and virtual devices as a key part of our daily life. This technology shift is expected to be greater than the Web and Mobile combined. As extremely different technologies are needed to build connected devices, the Internet of Things field is a junction between electronics, telecommunications and software engineering.
Internet of Things application development happens in silos, often using proprietary and closed communication protocols. There is the common belief that only if we can solve the interoperability problem we can have a real Internet of Things. After a deep analysis of the IoT protocols, we identified a set of primitives for IoT applications. We argue that each IoT protocol can be expressed in term of those primitives, thus solving the interoperability problem at the application protocol level. Moreover, the primitives are network and transport independent and make no assumption in that regard. This dissertation presents our implementation of an IoT platform: the Ponte project.
Privacy issues follows the rise of the Internet of Things: it is clear that the IoT must ensure resilience to attacks, data authentication, access control and client privacy. We argue that it is not possible to solve the privacy issue without solving the interoperability problem: enforcing privacy rules implies the need to limit and filter the data delivery process. However, filtering data require knowledge of how the format and the semantics of the data: after an analysis of the possible data formats and representations for the IoT, we identify JSON-LD and the Semantic Web as the best solution for IoT applications. Then, this dissertation present our approach to increase the throughput of filtering semantic data by a factor of ten.

description: Although ability to digest lactose generally declines after weaning in all mammals, in some human populations it persists also in adult individuals, a condition named lactase persistence (LP). Studies on the prevalence of the LP phenotype in worldwide human populations have shown that the frequency of this trait is highly variable in different ethnic groups, appearing to be positively correlated with the importance of milk in the diet. In particular, several single-nucleotide polymorphisms (SNPs) in the proximity of the LCT gene have been proved to be associated with LP. Nevertheless, few studies have till now analyzed genetic variation underlying LP in a wide set of Eurasian populations and, especially, in the Italian one. In the present study, we thus typed 40 SNPs surrounding the LCT gene in more than 1,000 samples from Italian and Arabic peninsulas to investigate patterns of LP-related genetic diversity in two regions which have played a pivotal role in the recent human evolutionary history according to their geographical position and historical/archaeological records. Our results underline a high and complex variability of the explored genomic region in both studied populations. In particular, a clear diversification of Northern Italian groups  from the rest of the peninsula, was observed, with the formers being genetically more similar to Northern European populations than to Southern Italians. These observation are consistent with known decreasing pattern of LP from Northern to Southern Italy and suggest the possibility of an independent evolution of LP-associated genotypes in Northern Italy. A similar scenario was observed in the Arabian peninsula, with Dhofari Arabs from Southern Oman and Yemeni clustering together with respect to Arabs from Northern Oman and the subgroup of Omanis of Asian origin which appeared instead to be genetically closer to Europeans than to the rest of Arabic groups.

description: Dependency of energy bandgap (Eg) of bilayer armchair graphene nanoribbons (AGNRB) on their widths, interlayer distance (D) and edge doping concentration of boron/nitrogen is investigated using local density approximation and compare to the results of monolayer graphene nanoribbons (AGNRM). Although Eg of AGNRB, in general, is smaller than that of AGNRM, AGNRB exhibits two distinct groups, metal and semiconductor, while AGNRM displays purely semiconducting behavior. Eg of AGNRB, moreover, is highly sensitive to D, indicating a possible application in tuning Eg by varying D. Finally, edge doping of both AGNR systems reduces Eg by 11-17%/4-10% for AGNRM/AGNRB, respectively.

description: Periodic and solitary travelling-wave solutions of an extended reduced Ostrovsky equation are investigated. Attention is restricted to solutions that, for the appropriate choice of certain constant parameters, reduce to solutions of the reduced Ostrovsky equation. It is shown how the nature of the waves may be categorized in a simple way by considering the value of a certain single combination of constant parameters. The periodic waves may be smooth humps, cuspons, loops or parabolic corner waves. The latter are shown to be the maximum-amplitude limit of a one-parameter family of periodic smooth-hump waves. The solitary waves may be a smooth hump, a cuspon, a loop or a parabolic wave with compact support. All the solutions are expressed in parametric form. Only in one circumstance can the variable parameter be eliminated to give a solution in explicit form. In this case the resulting waves are either a solitary parabolic wave with compact support or the corresponding periodic corner waves.

description: Many string constructions have a classical no-scale structure, resulting in a one-parameter model (OPM) for the supersymmetry breaking soft terms. As a highly constrained subset of mSUGRA, the OPM has the potential to be predictive. Conversely, if the observed superpartner spectrum at LHC is a subset of the OPM parameter space, then this may provide a clue to the underlying theory at high energies. We investigate the allowed supersymmetry parameter space for a generic one-parameter model taking into account the most recent experimental constraints. We find that in the strict moduli scenario, there are no regions of the parameter space which may satisfy all constraints. However, for the dilaton scenario, there are small regions of the parameter space where all constraints may be satisfied and for which the observed dark matter density may be generated. We also survey the possible signatures which may be observable at the Large Hadron Collider (LHC). Finally, we compare collider signatures of OPM to those from a model with non-universal soft terms, in particular those of an intersecting D6-brane model. We find that it may be possible to distinguish between these diverse scenarios at LHC.

title: The United Nations and terrorism : a long term assessment of changes and continuities
Creators: name: Müller, Johannes-Alexander
Publisher: name: University of St Andrews

description: Although terrorism continues to retain its localised nature in some respects, the threat has taken on an international character for some time now. Consequently, national efforts to curb terrorism are not sufficient in dealing with the threat, underscoring the importance of multilateral counterterrorism cooperation. The United Nations (UN) is perhaps the most visible and predominant international organisation for security issues and has thus built the prime case study for this research endeavour. The aim of this thesis has been to examine how the UN’s response to terrorism has changed since the 1970s. In doing so, the project has provided an empirical overview of 50 years of UN counterterrorism efforts and has analysed the empirical data to identify patterns, continuities, and disruptions in the UN’s response. The findings suggest that the United Nations has seen both change and continuity in its efforts to quell terrorist violence and it has been demonstrated that, while multilateral counterterrorism cooperation is possible at the UN, it is cumbersome and progress is best done away from the political limelight. The obstacles that have prevented swift action when the UN General Assembly first took up the issue in 1972 have remained remarkably consistent and are unlikely to be solved quickly. The step-by-step criminalisation of certain offences through treaty-making has however allowed the Assembly to make some progress. Following the Cold War, the Security Council has — although not spared from definitional short-comings — responded to terrorism in a more assertive (e.g. sanctions) and at times forceful manner. Finally, it has been highlighted that the politised nature of terrorism can greatly limit counterterrorism responses. Therefore, it has been suggested that future academic inquiry must explore the extent to which less politised organisations, those that are technical and regional in nature, might be better suited to address terrorism within their framework.

description: Four stars pulsating simultaneously with a dominant period $P_D$$\in$(0.28,0.39) d and an {\it additional} period $P_A$$\in$(0.20,0.27) d have been identified from among the more than 3000 RR Lyrae stars observed by the Kepler space telescope during NASA's K2 Mission. All four stars are located in the direction of the Galactic Bulge and have period ratios, $P_A$/$P_D$, significantly smaller than those of most double-mode RR Lyrae (RRd) stars: $P_A$/$P_D$$\in$(0.694,0.710) vs. $P_1$/$P_0$$\in$(0.726,0.748). Three of the stars are faint ($$=18--20 mag) and distant and are among the `peculiar' RRd (pRRd) stars discovered by Prudil et al. (2017); the fourth star, EPIC 216764000 (=V1125 Sgr), is a newly discovered pRRd star several magnitudes brighter than the other three stars. In this paper the high-precision long-cadence K2 photometry is analyzed in detail and used to study the cycle-to-cycle light variations. The pulsational characteristics of pRRd stars are compared with those of `classical' and `anomalous' RRd (cRRd, aRRd) stars. The conclusion by Prudil et al. that pRRd stars form a separate group of double-mode pulsators and are not simply very-short-period cRRd stars is confirmed. V1127 Aql and AH Cam are identified as other probable members of the class of pRRd stars.
