description: Although the group delay of classical pulses through a barrier may suggest superluminality, the information transfer is limited by the precursor which propagates at the vacuum light speed. Single photons, however, have infinite tails, and the question of causality becomes meaningless. We solve this problem by introducing strictly localized states close to single photons, which are examples of optical states produced by on-demand single-photon sources. These states can be arbitrarily close to single photons while demonstrating causality for their leading edge.

The pectoral cross was commonly worn by bishops and abbots in the medieval period. The figure style and the particular iconographic feature of the Dextera Dei also link the cross with monumental pre-Conquest stone sculptures, such as Stepney and Romsey, datable to the late 10th or early 11th century.

description: Let $K_\infty/K$ be a uniform $p$-adic Lie extension. We compare several arithmetic invariants of Iwasawa modules of ideal class groups on the one side and fine Selmer groups of abelian varieties on the other side.
 If $K_\infty$ contains sufficiently many $p$-power torsion points of $A$, then we can compare the ranks and the Iwasawa $μ$-invariants of these modules over the Iwasawa algebra. In several special cases (e.g. multiple $\mathbb{Z}_p$-extensions), we can also prove relations between suitable generalisations of the Iwasawa $λ$-invariant of the two types of Iwasawa modules.
 In the literature, different kinds of Iwasawa $λ$-invariants have been introduced for ideal class groups and Selmer groups. We define analogues of both concepts for fine Selmer groups and compare the resulting invariants.
 In order to obtain some of our main results, we prove new asymptotic formulas for the growth of ideal class groups and fine Selmer groups in multiple $\mathbb{Z}_p$-extensions.

description: In his celebrated textbook, $\textit{Quantum Mechanics: Nonrelativistic Theory}$, Landau argued that, for single particle systems in 1D, tunneling probability remains the same for a particle incident from the left or the right of a barrier. This left-right symmetry of tunneling probability holds regardless of the shape of the potential barrier. However, there are a variety of known cases that break this symmetry, e.g. when observing composite particles. We computationally (and analytically, in the simplest case) show this breaking of the left-right tunneling symmetry for Bose-Einstein condensates (BEC) in 1D, modelled by the Gross-Pitaevskii equation (GPE). By varying $g$, the parameter of inter-particle interaction in the BEC, we demonstrate that the transition from symmetric ($g=0$) to asymmetric tunneling is a threshold phenomenon. Our computations employ experimentally feasible parameters such that these results may be experimentally demonstrated in the near future. We conclude by suggesting applications of the phenomena to design atomtronic diodes, synthetic gauge fields, Maxwell's demons, and black-hole analogues.

It explains the data collection process, types of data collected, and data coverage and quality. Several summary statistics of the data by selected vessel and trip characteristics are also presented. A modeling framework for estimation and prediction of costs is also given. This process will allow estimation of vessel level aggregate trip cost, which in combination with a vessel's annual cost can give an overall fisheries cost assessment.

Transportation, Travel Behaviour and Low Carbon Society: An Overview
Creators: name: SINNIAH, GOBI
Publisher: name: Tema. Journal of Land Use, Mobility and Environment
Year: 2014

description: Travel behaviour trends have increased drastically all over the world. It is important to understand the needs to change travel behaviour as one of the initiative to achieve sustainable transportation. In achieving transportation sustainability, understanding on travel behaviour and needs can be more functional and useful for transportation planners to encourage people to use public transportations. In recent years, Low Carbon Society (LCS) concept has taken place to change the people lifestyles, especially to increase the use of public transportation. Undeniably, the only solution to a more sustainable transportation leading to a low carbon society is through a higher adoption rate of public transportation. However, it is a doubt achievement because of the lack of understanding on the social needs to increase mode choice in public transportation. The planning of the fast developing region of Iskandar Malaysia, which is one of the major economic growth conurbation located in southern part of Peninsular Malaysia, provides a good opportunity to transportation and urban planners to incorporate the ideas of low carbon society into designing a sustainable transportation systems. Thus, this paper aims to discuss the issues and potential implementation of the ideas to change the travel behaviour of people. This paper also provides current findings of transportation studies on the ongoing research to achieve a low carbon society in Iskandar Malaysia.

Realistic non-Gaussian operations scheme in parity detection based Mach-Zehnder quantum interferometry

Publisher: name: arXiv
Year: 2022

description: We theoretically analyze phase sensitivity using parity detection based Mach Zehnder interferometer (MZI) with the input states generated by performing non-Gaussian operations, viz., photon subtraction, photon addition, and photon catalysis on a two-mode squeezed vacuum (TMSV) state. Since these non-Gaussian operations are probabilistic, it is of utmost importance to take the success probability into account. To this end, we consider the realistic model of photon subtraction, addition, and catalysis and derive a single expression of the Wigner function for photon subtracted, added, and catalyzed TMSV state. The Wigner function is used to evaluate the lower bound on the phase sensitivity via quantum Cramer-Rao bound and parity detection based phase sensitivity in MZI. We identify the ranges of squeezing and transmissivity parameters where the non-Gaussian states provide better phase sensitivity than the TMSV state. On qualitatively taking the success probability into account, it turns out that the photon addition is the most advantageous non-Gaussian operation. We hope that the generalized Wigner function derived in this work will be useful in various quantum information protocols and state characterization.

description: We define a new dilaton Weyl multiplet of ${\mathcal{N}}=2$ conformal supergravity in four dimensions. This is constructed by reinterpreting the equations of motion of an on-shell hypermultiplet as constraints that render some of the fields of the standard Weyl multiplet composite. The independent bosonic components include four scalar fields and a triplet of gauge two-forms. The resulting, so-called, hyper-dilaton Weyl multiplet defines a $24+24$ off-shell representation of the local ${\mathcal{N}}=2$ superconformal algebra. By coupling the hyper-dilaton Weyl multiplet to an off-shell vector multiplet compensator, we obtain one of the two minimal $32+32$ off-shell multiplets of ${\mathcal{N}}=2$ Poincaré supergravity constructed by Müller in 1986. On-shell, this contains the minimal ${\mathcal{N}}=2$ Poincaré supergravity multiplet together with a hypermultiplet where one of its physical scalars plays the role of a dilaton, while its three other scalars are dualised to a triplet of real gauge two-forms. Interestingly, a $BF$-coupling induces a scalar potential for the dilaton without a standard gauging.

description: Enabling widespread electric vehicle (EV) adoption requires substantial build-out of charging infrastructure in the coming decade. We formulate the charging infrastructure needs as a scaling analysis problem and use it to estimate the EV infrastructure needs of the US at a county-level resolution. Surprisingly, we find that the current EV infrastructure deployment scales super-linearly with population, deviating from the sub-linear scaling of gasoline stations and other infrastructure. We discuss how this demonstrates the infancy of EV station abundance compared to other mature transportation infrastructures. By considering the power delivery of existing gasoline stations, and appropriate EV efficiencies, we estimate the EV infrastructure gap at the county level, providing a road map for future EV infrastructure expansion. Our reliance on scaling analysis allows us to make a unique forecast in this domain.

description: We study the problem of implementing arbitrary permutations of qubits under interaction constraints in quantum systems that allow for arbitrarily fast local operations and classical communication (LOCC). In particular, we show examples of speedups over swap-based and more general unitary routing methods by distributing entanglement and using LOCC to perform quantum teleportation. We further describe an example of an interaction graph for which teleportation gives a logarithmic speedup in the worst-case routing time over swap-based routing. We also study limits on the speedup afforded by quantum teleportation - showing an $O(\sqrt{N \log N})$ upper bound on the separation in routing time for any interaction graph - and give tighter bounds for some common classes of graphs.

description: Throughout the Cold War, US officials feared that Washington’s disloyalty to one ally would automatically cause other allies to doubt America’s security reliability. These doubts could prompt allies to adopt policies of neutrality, or even defect to the Communist bloc. This dissertation challenges the conventional wisdom—that alliance interdependence is underpinned by loyalty—by proposing the “alliance audience effect”. The alliance audience effect framework shows that discrete alliance commitments can be practically interdependent, but that this interdependence is not underpinned by loyalty. Through an investigation of Cold War case studies, using a process tracing methodology and archival research, this dissertation argues that US allies in Asia were unconcerned about whether America was loyal to other allied states. Instead, they monitored America’s behaviour in order to reassure themselves that the US was reliable: that their own alliance did not pose risks of either abandonment or entrapment. When allies feared abandonment, they encouraged America to solidify its presence in Asia and adopt a more aggressive posture. But when allies feared entrapment, they encouraged conciliatory US policies and worked to restrain Washington, thus reducing the risk of conflict. In some cases, American disloyalty to one ally was welcomed, or even encouraged, by other allies, as this disloyalty better served their own interests. Like the adage that “one man’s terrorist is another man’s freedom fighter”, this dissertation shows that one state’s disloyal ally can be another state’s reliable ally. Because US allies have different interests, they will have different views of American behaviour: one ally might praise an instance of US disloyalty as proof of reliability, while another ally might condemn Washington for unreliability. In short, reliability is not synonymous with loyalty, and America does not have a collective alliance loyalty reputation. Beyond the allied perspective, this research also demonstrates how the United States managed its alliances and used alliance interdependence to achieve its own ends. This dissertation’s findings have relevance for the alliance politics literature, theories about international reputation, and the practical management of alliances.

description: Cultural festivals are part and parcel of life. Civilization produced erroneous image of African cultures as awkward, barbaric, fetish, archaic and useless others regard cultural festivals as channels through which literature and language learning can be developed interaction at communal level, nationally and internationally to enhance economic advancement. However, cultural festivals are bundles of traditional heritage, recreation, values, and avenue for transmitting and enhancing socialization, can be harnessed for socioeconomic development. This paper projects the impact of literature and language with a positive orientation to cultural values. It enunciates the values and roles of cultural festivals in human and societal development, language learning, and by extension literature. It bemoans the negligence of people at cultural festivals in Nigeria. This highlights the role of festivals in promoting literature and language learning for economic advancement. Strategies that could be used to promote literature and language learning for school development were identified. It concludes with an emphasis on the fact that festivals bind us together and recommend parents, teachers, schools, and societal authorities to take advantage of those festivals to enhance the teaching and learning of language, both oral and written literature, in schools and at home for our nation’s economic interactions, exposure, and venture making

description: We study a family of adversarial multiclass classification problems and provide equivalent reformulations in terms of: 1) a family of generalized barycenter problems introduced in the paper and 2) a family of multimarginal optimal transport problems where the number of marginals is equal to the number of classes in the original classification problem. These new theoretical results reveal a rich geometric structure of adversarial learning problems in multiclass classification and extend recent results restricted to the binary classification setting. A direct computational implication of our results is that by solving either the barycenter problem and its dual, or the MOT problem and its dual, we can recover the optimal robust classification rule and the optimal adversarial strategy for the original adversarial problem. Examples with synthetic and real data illustrate our results.

description: The Ehrhart polynomial $ehr_P (n)$ of a lattice polytope $P$ gives the number of integer lattice points in the $n$-th dilate of $P$ for all integers $n\geq 0$. The degree of $P$ is defined as the degree of its $h^\ast$-polynomial, a particular transformation of the Ehrhart polynomial with many useful properties which serves as an important tool for classification questions in Ehrhart theory. A zonotope is the Minkowski (pointwise) sum of line segments. We classify all Ehrhart polynomials of lattice zonotopes of degree $2$ thereby complementing results of Scott (1976), Treutlein (2010), and Henk-Tagami (2009). Our proof is constructive: by considering solid-angles and the lattice width, we provide a characterization of all $3$-dimensional zonotopes of degree $2$.

In this paper, we present GWFish, a new software to simulate GW detector networks and to calculate measurement uncertainties based on the Fisher-matrix approximation. GWFish models the impact of detector motion on PE and makes it possible to analyze multiband scenarios, i.e., observation of a GW signal by different detectors in different frequency bands. We showcase a few examples for the Einstein Telescope (ET) including the sky-localization of binary neutron stars, and ET's capability to measure the polarization of GWs.

description: We present a nonlinear stability theory for periodic wave trains in reaction-diffusion systems, which relies on pure $L^\infty$-estimates only. Our analysis shows that localization or periodicity requirements on perturbations, as present in the current literature, can be completely lifted. Inspired by previous works considering localized perturbations, we decompose the semigroup generated by the linearization about the wave train and introduce a spatio-temporal phase modulation to capture the most critical dynamics, which is governed by a viscous Burgers' equation. We then aim to close a nonlinear stability argument by iterative estimates on the corresponding Duhamel formulation, where, hampered by the lack of localization, we must rely on diffusive smoothing to render decay of the semigroup. Yet, this decay is not strong enough to control all terms in the Duhamel formulation. We address this difficulty by applying the Cole-Hopf transform to eliminate the critical Burgers'-type nonlinearities. Ultimately, we establish nonlinear stability of diffusively spectrally stable wave trains against $C_{\mathrm{ub}}$-perturbations. Moreover, we show that the perturbed solution converges to a modulated wave train, whose phase and wavenumber are approximated by solutions to the associated viscous Hamilton-Jacobi and Burgers' equation, respectively.

Auger and conversion electron spectroscopy of medical isotopes and the construction of a new atomic radiation database

description: A localized source of electrons can be provided by radioisotopes that emit Auger electrons through atomic relaxation as part of their electron capture and/or internal conversion decays. Most of these Auger electrons could deposit their energies over short distances (nanometre to micrometre) in human body, making them an attractive tool to be used for highly-targeted radiation therapy. In this thesis, a semi-empirical energy correction method is developed to correct for the overestimated X-ray and Auger transition energies in the Monte-Carlo atomic relaxation model BrIccEmis. The improved model is tested against selected Auger electron experimental data, including our own measurements. The Auger and conversion electrons of the widely-used medical isotopes, 125I and 99Mo, are measured together at high-resolutions (3 eV to 9 eV) using the cylindrical mirror analyzer and the hemispherical electrostatic spectrometer. The relatively well-known conversion electrons are used to calibrate the Auger electrons to obtain accurate Auger yields. The full electron spectra (0 eV to 35 keV) from the electron capture of 125I are measured and analyzed. A new set of nuclear parameters, namely the penetration parameter and mixing ratio, of the 35.5-keV M1 transition from the decay of 125I is obtained. The measurements are compared with BrIccEmis calculations and overall a reasonable agreement is found. A method to prepare thin 99Mo sources on alumina substrates is developed, and the resulting sources are found to have thicknesses of about 20 nm. The electron spectra (200 eV to 2.3 keV) from the beta-decay of 99Mo are measured and analyzed. However, due to the relatively thick molybdenum sources, a quantitative result could not be obtained from the measured Auger electron spectra. One possible way to improve the source quality, which is to use an evaporated aluminum on alumina substrate for the deposition, is discussed. Finally, an atomic radiation database called BrIccEmisDB is constructed based the calculations on the BrIccEmis code. The database could provide quick and detailed X-ray and Auger spectra from nuclear decays, particle-impact ionizations, or any other type of ionization events. The BrIccEmisDB database is shown to be more accurate than the widely used radiation programs MIRD-RADTABS and Geant4, especially at low energies (less than 1 keV), through comparisons with experiments.
Extinction of multiple shocks in the modular Burgers equation

description: We consider multiple shock waves in the Burgers' equation with a modular advection term. It was previously shown that the modular Burgers' equation admits a traveling viscous shock with a single interface, which is stable against smooth and exponentially localized perturbations. In contrast, we suggest in the present work with the help of energy estimates and numerical simulations that the evolution of shock waves with multiple interfaces leads to finite-time coalescence of two consecutive interfaces. We formulate a precise scaling law of the finite-time extinction supported by the interface equations and by numerical simulations.

Mapping Melmoth: Maturin in/and the World Republic of Letters

Subjects: classificationCode: 47

description: This article offers a transnational mapping of Melmoth the Wanderer (1820) that links fictional narrative both to the contexts of its production and dissemination in a global literary marketplace and to its network of influence, and more particularly, its reputation and afterlife within what Pascale Casanova has influentially called ‘the world republic of letters’. It first considers Melmoth’s internal geography and the novel’s use of space in relation to Maturin’s quest for ‘literary capital’.1 It then expands upon, in Casanova’s terms, Melmoth’s ‘littérisation’, namely, the process by which, in spite of its often-unfavourable contemporary reception, Melmoth was transformed from a state of ‘literary inexistence to existence’ via translation and adaptation. Finally, it explores Northern Irish Big Telly Theatre Company’s 2012 dramatic adaptation as evidence of Melmoth’s littérisation. 2

description: Simple bone tools of the types shown here are known from various early medieval towns. They were used in different stages of cloth production. The circular spindle whorls, sawn from the long-bones of cattle, would weight a spindle, used in spinning thread. The plain long bones, each with one pointed end, are pin-beaters, used during weaving on a loom to push up the horizontal threads. The needles, used in sewing, have seen much use; their surfaces are highly polished. More information on Anglo-Saxon Exeter: http://www.rammtimetrail.org.uk

description: Federated learning (FL) has recently emerged as a distributed machine learning paradigm for systems with limited and intermittent connectivity. This paper presents the new context brought to FL by satellite constellations, where the connectivity patterns are significantly different from the ones observed in conventional terrestrial FL. The focus is on large constellations in low Earth orbit (LEO), where each satellites participates in a data-driven FL task using a locally stored dataset. This scenario is motivated by the trend towards mega constellations of interconnected small satellites in LEO and the integration of artificial intelligence in satellites. We propose a classification of satellite FL based on the communication capabilities of the satellites, the constellation design, and the location of the parameter server. A comprehensive overview of the current state-of-the-art in this field is provided and the unique challenges and opportunities of satellite FL are discussed. Finally, we outline several open research directions for FL in satellite constellations and present some future perspectives on this topic.

description: A mint striking silver pence for the king had been established at Exeter in Alfred's reign but its early issues are very rare. Output expanded enormously under Aethelred II ('the Unready'), when mints throughout the country were used to provide payments to Viking armies. The view shows the six principal types of coin struck under Aethelred. Each type has a standardised design, with the royal portrait on the obverse and the name of the mint and moneyer on the reverse. The museum holds 64 different coins of Aethelred's reign; many derive from Viking hoards found in Scandinavia. More information on Anglo-Saxon Exeter: http://www.rammtimetrail.org.uk
Boundary $h^\ast$-polynomials of rational polytopes

description: If $P$ is a lattice polytope (i.e., $P$ is the convex hull of finitely many integer points in $\mathbb{R}^d$) of dimension $d$, Ehrhart's famous theorem (1962) asserts that the integer-point counting function $|nP \cap \mathbb{Z}^d|$ is a degree-$d$ polynomial in the integer variable $n$. Equivalently, the generating function $1 + \sum_{n\geq 1} |nP \cap \mathbb{Z}^d| \, z^n$ is a rational function of the form $\frac{ h^\ast(z) }{ (1-z)^{ d+1 } }$; we call $h^\ast(z)$ the $h^\ast$-polynomial of $P$. There are several known necessary conditions for $h^\ast$-polynomials, including results by Hibi (1990), Stanley (1991), and Stapledon (2009), who used an interplay of arithmetic (integer-point structure) and topological (local $h$-vectors of triangulations) data of a given polytope. We introduce an alternative ansatz to understand Ehrhart theory through the $h^\ast$-polynomial of the boundary of a polytope, recovering all of the above results and their extensions for rational polytopes in a unifying manner. We include applications for (rational) Gorenstein polytopes and rational Ehrhart dilations.
