description: In the absence of suitable scientific campaign identified to provide one or more abundance indices for the mur-west stock, abundance indices based on commercial fishing data are of interest. They can be constructed using two approaches: a "design-based" approach (already initiated during the ROMELIGO zone 8 project) and a "model-based" approach. The present document refers to the first approach. For this ICES zone 8, an update of the data for the 5 fleets already identified (trawlers and gillnetters) has been carried out and completed by an analysis for the vessels using Danish seine. In addition, the methodology was applied to ICES zone 7, and the relevance of developing a global indicator for the combination of zones 7 + 8 was discussed in order to take into account the entire geographical area delimiting the mur-west stock. For Danish seine in zone 8, the fleet identified corresponds to vessels with an average size of 22.0 m (between 18.0 and 24.9 m), average tonnage of 149 GRT (between 88 and 227 GRT) and average power of 459 kW (between 331 and 626 kW) using 70-80 mm mesh with activity in quarter 2. We do not propose a Danish seine reference fleet for zone 7. For bottom otter trawls in zone 7, we do not propose an indicator of red mullet abundance due to the spatial distribution of catches that could be attributed to the mur.27.3a47d stock (not included in the study). For gillnetts, catches in zone 7 are very close to those in zone 8, which led us to propose an overall indicator for zones 7 + 8. Among the fleets identified, it is proposed to retain vessels with an average size of 10.8 m (between 7.5 and 14.8 m), an average tonnage of 11.4 GRT (between 2.0 and 31.0 GRT) and an average power of 151 kW (between 70 and 525 kW) using mesh sizes 50-59 mm in quarter 3 even if if attention must be paid to its use and are detailled in the document. The second approach (model-based ») is currently under development and will be communicated to the WGWIDE at a later date.

description: Solid waste management is one of the most important environmental issues worldwide, particularly in MENA countries. The present study was carried out in the city of Algiers, the capital city of Algeria. This urban area is marked by an increase in waste flow combined with a demographic surge. In order to investigate waste production and its drivers, we used both multiple regression and correlation analyses to test this dependence. Geospatial analysis was performed using principal component analysis integrated with GIS in order to look at the spatial distribution of waste management and potential drivers of waste production. The results indicate that household waste management is influenced by drivers related to the size of the settlement and the characteristics of waste management companies ( ≤ 0.05). The findings also show that none of the sociodemographic variables were found to significantly influence waste production. However, the spatial distribution is influenced by the geographic and sociodemographic characteristics of Algeria at all territorial levels. Algiers is still a landfill-based city in the MENA region, where mixed waste collection prevails in all districts. This study reinforces the importance of expanding source-separated waste collection schemes in order to increase the household waste diversion from landfills and, more importantly, shows how modern tools such as GIS, principal component analysis, and spatial analysis urban planning are useful for monitoring household waste, in line with circular economy principles.

description: Nowadays, a problem of historical beadworks conservation in museum collections is actual more than ever because of fatal corrosion of the 19th century glass beads. Vibrational spectroscopy is a powerful method for investigation of glass, namely, of correlation of the structure-chemical composition. Therefore, Fourier-transform infrared spectroscopy was used for examination of degradation processes in cloudy turquoise glass beads, which in contrast to other color ones deteriorate especially strongly. Micro-X-ray fluorescence spectrometry of samples has shown that lead-potassium glass PbO-K$_2$O-SiO$_2$ with small amount of Cu and Sb was used for manufacture of cloudy turquoise beads. Fourier-transform infrared spectroscopy study of the beads at different stages of glass corrosion was carried out in the range from 200 to 4000 cm$^{-1}$ in the attenuated total reflection mode. In all the spectra, we have observed shifts of two major absorption bands to low-frequency range (~1000 and ~775 cm$^{-1}$) compared to ones typical for amorphous SiO2 (~1100 and 800 cm$^{-1}$, respectively). Such an effect is connected with Pb$^{2+}$ and K$^+$ appending to the glass network. The presence of a weak band at ~1630 cm$^{-1}$ in all the spectra is attributed to the adsorption of H$_2$O. After annealing of the beads, the band disappeared completely in less deteriorated samples and became significantly weaker in more destroyed ones. Based on that we conclude that there is adsorbed molecular water on the beads. However, products of corrosion (e.g., alkali in the form of white crystals or droplets of liquid alkali) were not observed on the glass surface. We have also observed glass depolymerisation in the strongly degraded beads, which is exhibited in domination of the band peaked at ~1000 cm$^{-1}$.

description: Abstract Asymmetric total synthesis of naturally occurring nonenolide (-)-mangiferaelactone was attempted through RCAM (ring closing alkyne metathesis) reaction. As the attempted RCAM reaction failed, the synthesis was finally achieved by successful exploration of a ring closing metathesis (RCM) reaction. 2-Propylthiophene was used as a masked synthon for n-heptyl glycoside, which served as main source for one of the RCM precursors and accessed by reductive desulfurization (Mozingo type reduction) of an appropriately substituted thiophene ribofuranoside. The other RCM precursor was accessed by applying an enzymatic kinetic resolution/Mitsunobu inversion sequence to an alkyne alcohol.

description: NiFe/NiFeO multilayers were fabricated by radio frequency magnetron sputtering and natural oxidation. Doping of Ni by only 5 at. % Fe results in enhanced layering quality as X-ray reflectivity reveals. Due to magnetostatic anisotropy, the multilayers were found to be in-plane magnetized. The influence of mild thermal annealing (T = 525 K) on the magnetic properties of NiFe/NiFeO multilayers is also investigated. Annealing results in the enhancement of perpendicular magnetic anisotropy, mainly due to an increase in the uniaxial volume anisotropy term. Temperature-dependent hysteresis measurements between 4–400 K revealed considerable enhancement of coercivity and appearance of exchange bias effect.

description: Feature extraction and dimension reduction for networks is critical in a wide variety of domains. Efficiently and accurately learning features for multiple graphs has important applications in statistical inference on graphs. We propose a method to jointly embed multiple undirected graphs. Given a set of graphs, the joint embedding method identifies a linear subspace spanned by rank one symmetric matrices and projects adjacency matrices of graphs into this subspace. The projection coefficients can be treated as features of the graphs, while the embedding components can represent vertex features. We also propose a random graph model for multiple graphs that generalizes other classical models for graphs. We show through theory and numerical experiments that under the model, the joint embedding method produces estimates of parameters with small errors. Via simulation experiments, we demonstrate that the joint embedding method produces features which lead to state of the art performance in classifying graphs. Applying the joint embedding method to human brain graphs, we find it extracts interpretable features with good prediction accuracy in different tasks.

description: We investigate the metastable behavior of reversible Markov chains on possibly countable infinite state spaces. Based on a new definition of metastable Markov processes, we compute precisely the mean transition time between metastable sets. Under additional size and regularity properties of metastable sets, we establish asymptotic sharp estimates on the Poincaré and logarithmic Sobolev constant. The main ingredient in the proof is a capacitary inequality along the lines of V. Maz'ya that relates regularity properties of harmonic functions and capacities. We exemplify the usefulness of this new definition in the context of the random field Curie-Weiss model, where metastability and the additional regularity assumptions are verifiable.

Supersymmetric hybrid inflation with non-minimal coupling to gravity

subject: FOS: Physical sciences

description: We have studied the paradigm of cosmic inflation using the simplest model based on the idea of supersymmetric hybrid inflation with non-minimal coupling to gravity, specially under the slow-roll approximation following the superconformal approach to supergravity. It is found that within a range of values of the non-minimal coupling parameter $ξ$, the model can accommodate the inflation data reported by the Planck ($n_s$ and upper limit of $r$) and BICEP2/Keck (upper limit of $r$) collaborations. The study shows that the most probable value of $ξ$ should be $\sim 0.0134\pm0.0005$. That is coupling is found to be very week. Within this range of $ξ$, the values of $r$ estimated from our model for $50 - 70$ e-foldings are found to be laying well below the upper limits set by the Planck and BICEP2/Keck collaborations. Similarly, values of $n_s$ obtained for the said parameters are in good agreement with its latest data of the Planck collaboration. The constraint equations for the running of the scalar spectral index $n_{sk}$ and its running $n_{skk}$ are derived from the numerical solutions of our model for these parameters. These equations can be used to test our model from the data of future cosmological observations.

title: Encounters in wartime Italy: British soldiers and Italian civilians, 1943-1944
Creators: name: Simonetti, Fabio
Publisher: name: University of Reading
Year: 2028

description: This thesis explores the history and memory of the wartime encounters between British soldiers and Italian civilians during the Allied occupation of Italy. By shifting the focus away from the widely researched battlefields of the Italian Campaign, this work seeks to examine different aspects of the intercultural relationships taking place in the multifaceted contexts of invasion, liberation and occupation. While the first part deals with the different liberations – or ‘first encounters’ – of Sicily, Naples, and Rome, the second part focuses on the shared experience and issues caused by the Allied occupation – which I referred to as an ‘impossible co-habitation’. This research examines the ‘ordinary’ encounters taking place between soldiers and civilians in Italian cities occupied by the Allies as well as the overlooked experience of British servicemen and servicewomen in the Italian ‘contact zone’. Among the many issues analysed are soldiers and civilians’ perceptions of each other, the exchange of goods and services, the occupation and exploitation of the Italians’ space, soldier-tourism, working relationships, criminality, war weddings, and sexual encounters. This interdisciplinary study is based on the analysis of a rich corpus of mostly unpublished oral history interviews (many of them recorded during my research trips to Italy and Britain), diaries, letters, memoirs as well as on official documentation, photographs, and artworks I researched in both national and local archives and collections. By giving voice to soldiers and civilians, adults and children, men and women, I aim to explore the widest possible range of experiences by moving beyond simplistic explanations based on predominant narratives, towards a more complex social history of wartime encounters. As war disrupts people’s everyday life, forcing individuals to move and leading to previously unimaginable encounters, it can, indeed, destroy and divide. Nonetheless, the wide range of experiences discussed in this thesis will show that war can also provide opportunities for human interconnection and appreciation of different cultures.

description: There have been extensive studies of a random walk among a field of immobile traps (or obstacles), where one is interested in the probability of survival as well as the law of the random walk conditioned on its survival up to time $t$. In contrast, very little is known when the traps are mobile. We will briefly review the literature on the trapping problem with immobile traps, and then review some recent results on a model with mobile traps, where the traps are represented by a Poisson system of independent random walks on ${\mathbb Z}^d$. Some open questions will be given at the end.

description: Probabilistic integration of a continuous dynamical system is a way of systematically introducing model error, at scales no larger than errors introduced by standard numerical discretisation, in order to enable thorough exploration of possible responses of the system to inputs. It is thus a potentially useful approach in a number of applications such as forward uncertainty quantification, inverse problems, and data assimilation. We extend the convergence analysis of probabilistic integrators for deterministic ordinary differential equations, as proposed by Conrad et al.\ (\textit{Stat.\ Comput.}, 2017), to establish mean-square convergence in the uniform norm on discrete- or continuous-time solutions under relaxed regularity assumptions on the driving vector fields and their induced flows. Specifically, we show that randomised high-order integrators for globally Lipschitz flows and randomised Euler integrators for dissipative vector fields with polynomially-bounded local Lipschitz constants all have the same mean-square convergence rate as their deterministic counterparts, provided that the variance of the integration noise is not of higher order than the corresponding deterministic integrator. These and similar results are proven for probabilistic integrators where the random perturbations may be state-dependent, non-Gaussian, or non-centred random variables.

description: Quantum reading refers to the task of reading out classical information stored in a read-only memory device. In any such protocol, the transmitter and receiver are in the same physical location, and the goal of such a protocol is to use these devices (modeled by independent quantum channels), coupled with a quantum strategy, to read out as much information as possible from a memory device, such as a CD or DVD. As a consequence of the physical setup of quantum reading, the most natural and general definition for quantum reading capacity should allow for an adaptive operation after each call to the channel, and this is how we define quantum reading capacity in this paper. We also establish several bounds on quantum reading capacity, and we introduce an environment-parametrized memory cell with associated environment states, delivering second-order and strong converse bounds for its quantum reading capacity. We calculate the quantum reading capacities for some exemplary memory cells, including a thermal memory cell, a qudit erasure memory cell, and a qudit depolarizing memory cell. We finally provide an explicit example to illustrate the advantage of using an adaptive strategy in the context of zero-error quantum reading capacity.

Tempered Monoids of Real Numbers, the Golden Fractal Monoid, and the Well-Tempered Harmonic Semigroup

description: This paper deals with the algebraic structure of the sequence of harmonics when combined with equal temperaments. Fractals and the golden ratio appear surprisingly on the way. The sequence of physical harmonics is an increasingly enumerable submonoid of (R+,+) whose pairs of consecutive terms get arbitrarily close as they grow. These properties suggest the definition of a new mathematical object which we denote a tempered monoid. Mapping the elements of the tempered monoid of physical harmonics from R to N may be considered tantamount to defining equal temperaments. The number of equal parts of the octave in an equal temperament corresponds to the multiplicity of the related numerical semigroup. Analyzing the sequence of musical harmonics we derive two important properties that tempered monoids may have: that of being product-compatible and that of being fractal. We demonstrate that, up to normalization, there is only one product-compatible tempered monoid, which is the logarithmic monoid, and there is only one nonbisectional fractal monoid which is generated by the golden ratio. The example of half-closed cylindrical pipes imposes a third property to the sequence of musical harmonics, the so-called odd-filterability property. We prove that the maximum number of equal divisions of the octave such that the discretizations of the golden fractal monoid and the logarithmic monoid coincide, and such that the discretization is odd-filterable is 12. This is nothing else but the number of equal divisions of the octave in classical Western music.

description: We introduce a framework for graphical security proofs in device-independent quantum cryptography using the methods of categorical quantum mechanics. We are optimistic that this approach will make some of the highly complex proofs in quantum cryptography more accessible, facilitate the discovery of new proofs, and enable automated proof verification. As an example of our framework, we reprove a previous result from device-independent quantum cryptography: any linear randomness expansion protocol can be converted into an unbounded randomness expansion protocol. We give a graphical proof of this result, and implement part of it in the Globular proof assistant.

description: We attach buildings to modular lattices and use them to develop a metric approach to Harder-Narasimhan filtrations. Switching back to a categorical framework, we establish an abstract numerical criterion for the compatibility of these filtrations with tensor products. We finally verify our criterion in three cases, one of which is new.

Small cancellation theory over Burnside groups
Creators: name: Coulon, Rémi
name: Gruber, Dominik
Publisher: name: arXiv
Year: 2017
Subjects: subject: Group Theory (math.GR)
subject: FOS: Mathematics

description: We develop a version of small cancellation theory in the variety of Burnside groups. More precisely, we show that there exists a critical exponent $n_0$ such that for every odd integer $n\geq n_0$, the well-known classical $C'(1/6)$-small cancellation theory, as well as its graphical generalization and its version for free products, produce examples of infinite $n$-periodic groups. Our result gives a powerful tool for producing (uncountable collections of) examples of $n$-periodic groups with prescribed properties. It can be applied without any prior knowledge in the subject of $n$-periodic groups. As applications, we show the undecidability of Markov properties in classes of $n$-periodic groups, we produce $n$-periodic groups whose Cayley graph contains an embedded expander graphs, and we give an $n$-periodic version of the Rips construction. We also obtain simpler proofs of some known results like the existence of uncountably many finitely generated $n$-periodic groups and the SQ-universality (in the class of $n$-periodic groups) of free Burnside groups.

Long time behavior of solutions to the 3D Hall-magneto-hydrodynamics system with one diffusion

description: This paper studies the asymptotic behavior of smooth solutions to the generalized Hall-magneto-hydrodynamics system (1.1) with one single diffusion on the whole space $\mathbb R^3$. We establish that, in the inviscid resistive case, the energy $\|b(t)\|_2^2$ vanishes and $\|u(t)\|_2^2$ converges to a constant as time tends to infinity provided the velocity is bounded in $W^{1-α,\frac3α}(\mathbb R^3)$; in the viscous non-resistive case, the energy $\|u(t)\|_2^2$ vanishes and $\|b(t)\|_2^2$ converges to a constant provided the magnetic field is bounded in $W^{1-β,\infty}(\mathbb R^3)$. In summary, one single diffusion, being as weak as $(-Δ)^αb$ or $(-Δ)^βu$ with small enough $α, β$, is sufficient to prevent asymptotic energy oscillations for certain smooth solutions to the system.

A highly predictive $A_{4}$ flavour 3-3-1 model with radiative inverse seesaw mechanism
Creators: name: Hernández, A. E. Cárcamo

description: We build a highly predictive 3-3-1 model, where the field content is extended by including several $SU(3)_{L}$ scalar singlets and six right handed Majorana neutrinos. In our model the $SU(3)_{C}\times SU\left( 3\right) _{L}\times U\left( 1\right) _{X}$ gauge symmetry is supplemented by the $A_{4}\times Z_{4}\times Z_{6}\times Z_{16}\times Z_{16}^{\prime }$ discrete group, which allows to get a very good description of the low energy fermion flavor data. In the model under consideration, the $A_{4}\times Z_{4}\times Z_{6}\times Z_{16}\times Z_{16}^{\prime }$ discrete group is broken at very high energy scale down to the preserved $Z_{2}$ discrete symmetry, thus generating the observed pattern of SM fermion masses and mixing angles and allowing the implementation of the loop level inverse seesaw mechanism for the generation of the light active neutrino masses, respectively. The obtained values for the physical observables in the quark sector agree with the experimental data, whereas those ones for the lepton sector also do, only for the case of inverted neutrino mass spectrum. The normal neutrino mass hierarchy scenario of the model is ruled out by the neutrino oscillation experimental data. We find an effective Majorana neutrino mass parameter of neutrinoless double beta decay of $% m_{ee}=46.9$ meV, a leptonic Dirac CP violating phase of $-81.37^{\circ}$ and a Jarlskog invariant of about $10^{-2}$ for the inverted neutrino mass hierarchy. The preserved $Z_{2}$ symmetry allows for a stable scalar dark matter candidate.

Improving Spectral Clustering using the Asymptotic Value of the Normalised Cut
Creators: name: Hofmeyr, David
Publisher: name: arXiv
Year: 2017
Subjects: subject: Machine Learning (stat.ML)
subject: FOS: Computer and information sciences

description: Spectral clustering is a popular and versatile clustering method based on a relaxation of the normalised graph cut objective. Despite its popularity, however, there is no single agreed upon method for tuning the important scaling parameter, nor for determining automatically the number of clusters to extract. Popular heuristics exist, but corresponding theoretical results are scarce. In this paper we investigate the asymptotic value of the normalised cut for an increasing sample assumed to arise from an underlying probability distribution, and based on this result provide recommendations for improving spectral clustering methodology. A corresponding algorithm is proposed with strong empirical performance.

New factorization theory for heavy quarkonium production and decay

description: The widely used nonrelativistic QCD (NRQCD) factorization theory now encounters some notable difficulties in describing quarkonium production. This may be due to the inadequate treatment of soft hadrons emitted in the hadronization process, which causes bad convergence of velocity expansion in NRQCD. In this paper, starting from QCD we propose a rigorously defined factorization approach, soft gluon factorization (SGF), to better deal with the effects of soft hadrons. After a careful velocity expansion, the SGF can be as simple as the NRQCD factorization in phenomenological studies, but has a much better convergence. The SGF may provide a new insight to understand the mechanisms of quarkonium production and decay.

Nonparametric inference for continuous-time event counting and link-based dynamic network models

Subjects: subject: Statistics Theory (math.ST)

description: A flexible approach for modeling both dynamic event counting and dynamic link-based networks based on counting processes is proposed, and estimation in these models is studied. We consider nonparametric likelihood based estimation of parameter functions via kernel smoothing. The asymptotic behavior of these estimators is rigorously analyzed by allowing the number of nodes to tend to infinity. The finite sample performance of the estimators is illustrated through an empirical analysis of bike share data.

On free Lie algebras and particles in electro-magnetic fields

description: The Poincaré algebra can be extended (non-centrally) to the Maxwell algebra and beyond. These extensions are relevant for describing particle dynamics in electro-magnetic backgrounds and possibly including the backreaction due the presence of multipoles. We point out a relation of this construction to free Lie algebras that gives a unified description of all possible kinematic extensions, leading to a symmetry algebra that we call Maxwell${}_\infty$. A specific dynamical system with this infinite symmetry is constructed and analysed.
