description: Recently, oil-water separation materials with special wettability surfaces have attracted intense attention. In this work, amphiphilic magnetic nanoparticles of Fe3O4@TiO2 are prepared by the homogeneous precipitation method. The prepared nanoparticles are characterized by X-ray diffraction, Fourier transform infrared spectroscopy, Dynamic light scattering, Zeta potential and contact angle. The prepared magnetic nanoparticles can effectively separate the simulated oily wastewater prepared with 0# diesel. The oil removal performance with magnetic nanoparticles Fe3O4@TiO2 is evaluated by a handheld oil meter after rotating at 250 rpm for a certain time. Results show that the prepared material has the best oil-water separation performance and maintains high magnetism when the weight ratio of TiO2 is 80%. When the dosage is 0.125% (w/v), the oil removal rate is up to 97% after 30 minutes of addition. These prepared materials are suitable for oil-water separation under neutral and acidic conditions and have good recycling performance. This indicates that the prepared amphiphilic magnetic nanoparticles have practical applications in the treatment of oily wastewater.

description: sensitive topics. In a list experiment, the sensitive topic is embedded in a list of non-sensitive topics and respondents are asked only to give a count of how many items apply, without saying which ones. This means that sensitive preferences and behaviors can only be observed in the aggregate and offers individual confidentiality, thus encouraging truthful responses. However, this technique necessarily assumes that sensitivity bias is uniform across respondent subgroups; this underscores the design and analysis of list experiments. . It's unclear how a list experiment can be used in a setting where social desirability varies across groups. Is the expectation that a list experiment will reveal a higher or lower estimated prevalence, considering that the bias from social desirability may cut in opposite directions? On a more technical level, many commonly used list experiment estimators and diagnostic tests rely on monotonicity assumptions which imply uniform SDB polarity. There is currently little guidance on how to adapt list experiment analysis. We use data from original surveys in order to probe these issues. Our overarching goals are: a) demonstrate empirically that subgroup variation in SDB is a common and generalisable phenomenon b) systematically explore the methodological consequences of subgroup variation in SDB

In particular this solves a conjecture of Navas in the positive. As a corollary we obtain a new proof of the fact that finitely generated free groups do not admit isolated left-invariant orderings.

To Own or to Access: Exploring the Sharing and Access Practices of Arab Millennials
Creators: name: Radwan, Maha Baz
Publisher: name: University of Leicester
Year: 2022
Subjects: Uncategorized

description: This study examines modern non-ownership practices like sharing and access in previously unexplored socio-demographic and cultural contexts. It focuses on millennial consumers – an influential segment globally who are fervent users of sharing economy services, in the Arab world – an emergent market for these services and home to a large concentration of millennials. This research explores how Arab millennials in Lebanon engage with sharing and access-based consumption practices with a focus on transportation sharing economy platforms, and it questions how these practices are perceived vis-à-vis ownership, the meaning and nature of trust within these practices and the role income level plays in these interactions. To formulate a more nuanced and culturally attuned understanding of the nonownership sharing and access practices, this research used practice theory as an enabling lens and was conducted using a qualitative methodology. The collected primary data included 36 semi-structured interviews with Lebanese Arab millennials, supplemented by participant observations and two interviews with sharing economy service providers. The data was then iteratively analysed using thematic analysis. The findings reveal the complex and contingent nature of non-ownership practices like sharing and access that goes beyond what was uncovered in the existing Western literature. The study suggests that to advance our understanding of these practices, more contextual studies need to be undertaken. The findings of this study would help academics and marketers better understand the different consumption practices within the sharing economy and how the rules, understandings, and teleoaffectivities within these practices interact to sustain or shift these practices between sharing, access, and ownership. This would result in a more attuned and sustainable sharing economy concept, taking this disruptive global business megatrend to the next level.
From Kleisli Categories to Commutative C*-algebras: Probabilistic Gelfand Duality

description: C*-algebras form rather general and rich mathematical structures that can be studied with different morphisms (preserving multiplication, or not), and with different properties (commutative, or not). These various options can be used to incorporate various styles of computation (set-theoretic, probabilistic, quantum) inside categories of C*-algebras. At first, this paper concentrates on the commutative case and shows that there are functors from several Kleisli categories, of monads that are relevant to model probabilistic computations, to categories of C*-algebras. This yields a new probabilistic version of Gelfand duality, involving the "Radon" monad on the category of compact Hausdorff spaces. We then show that the state space functor from C*-algebras to Eilenberg-Moore algebras of the Radon monad is full and faithful. This allows us to obtain an appropriately commuting state-and-effect triangle for C*-algebras.

description: Public opinion plays a crucial role facilitating development and implementation of environmental policies. Recent literature has focused on how support varies by policy designs. Notably, choice experiment designs have commonly been adopted to identify variance in support by policy instruments and packages. Particularly, empirical findings suggest that support varies across dimensions of market/non-market and push/pull instruments. Yet, a full comparison of these four ideal policy design types has yet to be empirically tested. Drawing upon survey data from the United Kingdom and Germany, we explore how support varies across ideal policy design types with regards to food consumption and air travel policies.

description: We separate Maxwell's equations for background media that allow for both electric and magnetic time-dependence in a generalized Lorenz gauge. In a process analogous to the dynamical Casimir effect (DCE) we discuss how surface plasmon polaritons (SPP)s can be created out of vacuum, via the time-dependent variation of a dielectric and magnetic insulator at a metal interface for TM and TE branches, respectively. We suggest how to extend currently proposed DCE experiments to set up and detect these excitations. Numerical simulations (without any approximation) indicate that vacuum excited SPPs can be of a similar magnitude to the photon creation rate in such experiments. Potential benefits of detecting vacuum excited SPPs, as opposed to DCE photons, are that parametric enhancement does not require a sealed cavity in the axial direction and the detection apparatus might be able to use simple phase matching techniques. For the case of constant permeability, $μ$, TM branch SPPs and photons do not suffer from detuning and attenuation like TE photons.

Suppose $T$ and $R$ are symmetric invariant (0,2)-tensor fields on $M$ and $\partial M$, respectively. The paper studies the prescribed Ricci curvature equation $\mathrm{Ric}(G)=T$ for a Riemannian metric $G$ on $M$ subject to the boundary condition $G_{\partial M}=R$ (the notation $G_{\partial M}$ here stands for the metric induced by $G$ on $\partial M$). Imposing a standard assumption on $M_1$, we describe a set of requirements on $T$ and $R$ that guarantee global and local solvability.

The device-independent outlook on quantum physics (lecture notes on the power of Bell's theorem)
Creators: name: Scarani, Valerio
Publisher: name: arXiv
Year: 2013
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: This text is an introduction to an operational outlook on Bell inequalities, which has been very fruitful in the past few years. It has lead to the recognition that Bell tests have their own place in applied quantum technologies, because they quantify non-classicality in a device-independent way, that is, without any need to describe the degrees of freedom under study and the measurements that are performed. At the more fundamental level, the same device-independent outlook has allowed the falsification of several other alternative models that could hope to reproduce the observed statistics while keeping some classical features that quantum theory denies; and it has shed new light on the long-standing quest for deriving quantum theory from physical principles.

description: We introduce a diffeomorphism invariant of $4$-manifolds, the $\mathrm{Pin}^-(2)$-monopole invariant, defined by using the $\mathrm{Pin}^-(2)$-monopole equations. We compute the invariants of several $4$-manifolds, and prove gluing formulae. By using the invariants, we construct exotic smooth structures on the connected sum of an elliptic surface $E(n)$ with arbitrary number of the $4$-manifolds of the form of $S^2\timesΣ$ or $S^1\times Y$ where $Σ$ is a compact Riemann surface with positive genus and $Y$ is a closed $3$-manifold. As another application, we give an estimate of the genus of surfaces embedded in a $4$-manifold $X$ representing a class $α\in H_2(X;l)$, where $l$ is a local coefficient on $X$.

description: Relaxation of soft modes (e.g. charge density in gated semiconductor heterostructures, spin density in the presence of magnetic field) slowed down by disorder may lead to giant enhancement of energy transfer (cooling power) between overheated electrons and phonons at low bath temperature. We show that in strongly disordered systems with time-reversal symmetry broken by external or intrinsic exchange magnetic field the cooling power can be greatly enhanced. The enhancement factor as large as $10^{2}$ at magnetic field $B \sim 10$ Tesla in 2D {\rm InSb} films is predicted. A similar enhancement is found for the ultrasound attenuation.

description: We say that a $q$-ary length $n$ code is \emph{non-overlapping} if the set of non-trivial prefixes of codewords and the set of non-trivial suffices of codewords are disjoint. These codes were first studied by Levenshtein in 1964, motivated by applications in synchronisation. More recently these codes were independently invented (under the name \emph{cross-bifix-free} codes) by Bajić and Stojanović. We provide a simple construction for a class of non-overlapping codes which has optimal cardinality whenever $n$ divides $q$. Moreover, for all parameters $n$ and $q$ we show that a code from this class is close to optimal, in the sense that it has cardinality within a constant factor of an upper bound due to Levenshtein from 1970. Previous constructions have cardinality within a constant factor of the upper bound only when $q$ is fixed. Chee, Kiah, Purkayastha and Wang showed that a $q$-ary length $n$ non-overlapping code contains at most $q^n/(2n-1)$ codewords; this bound is weaker than the Levenshtein bound. Their proof appealed to the application in synchronisation: we provide a direct combinatorial argument to establish the bound of Chee \emph{et al}. We also consider codes of short length, finding the leading term of the maximal cardinality of a non-overlapping code when $n$ is fixed and $q\rightarrow \infty$. The largest cardinality of non-overlapping codes of lengths $3$ or less is determined exactly.

description: In this article, we consider a fundamental decentralized optimal control problem, which we call the two-player problem. Two subsystems are interconnected in a nested information pattern, and output feedback controllers must be designed for each subsystem. Several special cases of this architecture have previously been solved, such as the state-feedback case or the case where the dynamics of both systems are decoupled. In this paper, we present a detailed solution to the general case. The structure of the optimal decentralized controller is reminiscent of that of the optimal centralized controller; each player must estimate the state of the system given their available information and apply static control policies to these estimates to compute the optimal controller. The previously solved cases benefit from a separation between estimation and control which allows one to compute the control and estimation gains separately. This feature is not present in general, and some of the gains must be solved for simultaneously. We show that computing the required coupled estimation and control gains amounts to solving a small system of linear equations.

description: Chamseddine and Connes have argued that the action for Einstein gravity, coupled to the SU(3)\times SU(2)\times U(1) standard model of particle physics, may be elegantly recast as the "spectral action" on a certain "non-commutative geometry." In this paper, we show how this formalism may be extended to "non-associative geometries," and explain the motivations for doing so. As a guiding illustration, we present the simplest non-associative geometry (based on the octonions) and evaluate its spectral action: it describes Einstein gravity coupled to a G_2 gauge theory, with 8 Dirac fermions (which transform as a singlet and a septuplet under G_2). This is just the simplest example: in a forthcoming paper we show how to construct more realistic models that include Higgs fields, spontaneous symmetry breaking and fermion masses.

description: We study the dynamics of iteration function systems generated by a pair of circle diffeomorphisms close to rotations in the $C^{1+\mathrm{bv}}$-topology. We characterize the obstruction to minimality and describe the limit set. In particular, there are no invariant minimal Cantor sets, which can be seen as a Denjoy/Duminy type theorem for iterated systems on the circle.

Higher Derivative Gravity and Conformal Gravity From Bimetric and Partially Massless Bimetric Theory

description: In this paper we establish the correspondence between ghost-free bimetric theory and a class of higher derivative gravity actions, including conformal gravity and New Massive Gravity. We also characterize the relation between the respective equations of motion and classical solutions. We illustrate that, in this framework, the spin-2 ghost of higher derivative gravity is an artifact of the truncation to a 4-derivative theory. The analysis also gives a relation between the proposed partially massless (PM) bimetric theory and conformal gravity, showing, in particular, the equivalence of their equations of motion at the 4-derivative level. For the PM bimetric theory this provides further evidence for the existence of an extra gauge symmetry and the associated loss of a propagating mode away from de Sitter backgrounds. The new symmetry is an extension of Weyl symmetry which also suggests the PM bimetric theory as a ghost-free completion of conformal gravity.

Sharp regularity near an absorbing boundary for solutions to second order SPDEs in a half-line with constant coefficients
Creators: name: Ledger, Sean
Publisher: name: arXiv
Year: 2013
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: We prove that the weak version of the SPDE problem \begin{align*} dV_{t}(x) & = [-μV_{t}'(x) + \frac{1}{2} (σ_{M}^{2} + σ_{I}^{2})V_{t}"(x)]dt - σ_{M} V_{t}'(x)dW^{M}_{t}, \quad x > 0, \\ V_{t}(0) &= 0 \end{align*} with a specified bounded initial density, $V_{0}$, and $W$ a standard Brownian motion, has a unique solution in the class of finite-measure valued processes. The solution has a smooth density process which has a probabilistic representation and shows degeneracy near the absorbing boundary. In the language of weighted Sobolev spaces, we describe the precise order of integrability of the density and its derivatives near the origin, and we relate this behaviour to a two-dimensional Brownian motion in a wedge whose angle is a function of the ratio $σ_{M}/σ_{I}$. Our results are sharp: we demonstrate that better regularity is unattainable.

description: This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. The interdisciplinary study of cochineal production in Mesoamerica has overwhelmingly focused on the written record. These documents, written by Spanish colonizers, European scientists, and modern-day ethnographers, yield insightful information into the material culture of cochineal production, from the cactus farm to the dye vat. Yet thus far, this information has not been used to generate hypotheses that can be tested by archaeological materials. This has limited archaeology’s contributions to cochineal studies, perpetuating a reliance on documents that often reflect biased and ethnocentric perspectives about Indigenous cochineal producers. In this paper, I draw from historical, ethnographic, and chemical information to reconstruct the stages of cochineal production. For each stage, I identify its associated artifacts, ecofacts, and features, as well as any modifications they may undergo in the process. I pair this analysis with preliminary experimental archaeology findings that suggest the utility of using carminic acid residues to positively identify artifacts modified by cochineal production. I then demonstrate how this approach can be used to test claims about cochineal production, including the antiquity of cochineal use in Mesoamerica, shifts in European demand for different cochineal products, and the reasons behind the decline in central Mexican production in the mid-1600s.
Approximately Optimal Scheduling of an M/G/1 Queue with Heavy Tails

description: Distributions with a heavy tail are difficult to estimate. If the design of a scheduling policy is sensitive to the details of heavy tail distributions of the service times, an approximately optimal solution is difficult to obtain. This paper shows that the optimal scheduling of an M/G/1 queue with heavy tailed service times does not present this difficulty and that an approximately optimal strategy can be derived by truncating the distributions.

The Recollector and On Dystopian Fiction and Memory
Creators: name: Taylor-McCartney, Paul
Publisher: name: University of Leicester
Year: 2022
Subjects: Uncategorized

description: This PhD submission comprises a novel of 60,000 words entitled The Recollector which is accompanied by a Reflective Commentary of 20,000 words that focuses on the theme of memory in dystopian fiction. The novel is narrated by Amos Blythe – a fortysomething male with a rare psychological condition that means he has almost total recall. As an epidemic emerges across the UK, with a high proportion of the working-age population presenting symptoms of memory dysfunction, Amos finds himself in direct conflict with those around him and a country that begins to focus on the present, rather than its past. The accompanying commentary reflects on the role of memory in dystopian fiction, in relation to my own creative practice and its critical and literary contexts. The opening chapter ‘Imagine if you can …’ discusses elements of writerly craft involved in the production of a dystopian novel and includes a review of some of the key literature that helped shape not only my thinking but also the narrative of The Recollector. The next chapter, ‘Genre Recall’, traces the antecedents of the dystopian novel, and suggests that genre itself possesses a memory of its own, requiring the writer to engage in various ‘recall’ processes when they set out to create an original work in that genre. It critically appraises a range of primary and secondary material and contains a series of reflections on how this has shaped my understanding of working in a genre, with a particular focus on the importance and function of memory. The final chapter, ‘Hideous Progeny’, examines the use of science and technology by authors in the dystopian genre, again, with a focus on memory. I argue that Mary Shelley’s Frankenstein (1818) qualifies as the first dystopian novel to contain a direct warning about the dangers of unchecked human ‘progress’ whilst being set in a world recognisable to readers at the time. I conclude that full engagement with the critical literature has informed some fundamental decisions I made on the creative side of the thesis but also helped refine my skills as both author and reflective practitioner.

Capacity of an associative memory model on random graph architectures

description: We analyze the storage capacity of the Hopfield models on classes of random graphs. While such a setup has been analyzed for the case that the underlying random graph model is an Erdös-Renyi graph, other architectures, including those investigated in the recent neuroscience literature, have not been studied yet. We develop a notion of storage capacity that highlights the influence of the graph topology and give results on the storage capacity for not too irregular random graph models. The class of models investigated includes the popular power law graphs for some parameter values.

title: One end to rule them all: Non-homologous end-joining and homologous recombination at DNA double-strand breaks
Creators: name: Ensminger, Michael
name: Löbrich, Markus
Publisher: name: British Institute of Radiology
Year: 2021

description: Double-strand breaks (DSBs) represent the most severe type of DNA damage since they can lead to genomic rearrangements, events that can initiate and promote tumorigenic processes. DSBs arise from various exogenous agents that induce two single-strand breaks at opposite locations in the DNA double helix. Such two-ended DSBs are repaired in mammalian cells by one of two conceptually different processes, non-homologous end-joining (NHEJ) and homologous recombination (HR). NHEJ has the potential to form rearrangements while HR is believed to be error-free since it uses a homologous template for repair. DSBs can also arise from single-stranded DNA lesions if they lead to replication fork collapse. Such DSBs, however, have only one end and are repaired by HR and not by NHEJ. In fact, the majority of spontaneously arising DSBs are one-ended and HR has likely evolved to repair one-ended DSBs. HR of such DSBs demands the engagement of a second break end that is generated by an approaching replication fork. This HR process can cause rearrangements if a homologous template other than the sister chromatid is used. Thus, both NHEJ and HR have the potential to form rearrangements and the proper choice between them is governed by various factors, including cell cycle phase and genomic location of the lesion. We propose that the specific requirements for repairing one-ended DSBs have shaped HR in a way which makes NHEJ the better choice for the repair of some but not all two-ended DSBs.
