description: The chiral primary operators of the D=6 superconformal (2,0) theory corresponding to 14 scalars of N=4 D=7 supergravity are obtained by expanding the world volume action for the M5-brane around an AdS_7 x S^4 background. In the leading order, the operators take their values in the symmetric traceless representation of the SO(5) R-symmetry group in consistency with the early conjecture on their structure based on the superconformal symmetry and Matrix-like model arguments.

description: Approximation algorithms for constraint satisfaction problems (CSPs) are a central direction of study in theoretical computer science. In this work, we study classical product state approximation algorithms for a physically motivated quantum generalization of Max-Cut, known as the quantum Heisenberg model. This model is notoriously difficult to solve exactly, even on bipartite graphs, in stark contrast to the classical setting of Max-Cut. Here we show, for any interaction graph, how to classically and efficiently obtain approximation ratios 0.649 (anti-ferromagnetic XY model) and 0.498 (anti-ferromagnetic Heisenberg XYZ model). These are almost optimal; we show that the best possible ratios achievable by a product state for these models is 2/3 and 1/2, respectively.

description: In its Communication "Building a European data economy" the EU Commission discusses the introduction of a new exclusive property right on data ("data producer right") for non-personal (or anonymised) machine-generated data, and mandatory access rights to privately held data for achieving more access, transfer and reuse of data, esp. in the context of "Internet of Things" applications. This article analyzes the problem of "rights on data" from an economic perspective (incentive problem, data markets, bargaining power problems, access problems in multi-stakeholder situations) and the reasonings and proposals in the Communication from an economic perspective. Important results are that a "data producer right" cannot be recom-mended but that access rights to data can be part of specifically tailored data governance solu-tions in certain sectors.

description: For mobile robots to operate autonomously in general environments, perception is required in the form of a dense metric map. For this purpose, we present the stochastic triangular mesh (STM) mapping technique: a 2.5-D representation of the surface of the environment using a continuous mesh of triangular surface elements, where each surface element models the mean plane and roughness of the underlying surface. In contrast to existing mapping techniques, a STM map models the structure of the environment by ensuring a continuous model, while also being able to be incrementally updated with linear computational cost in the number of measurements. We reduce the effect of uncertainty in the robot pose (position and orientation) by using landmark-relative submaps. The uncertainty in the measurements and robot pose are accounted for by the use of Bayesian inference techniques during the map update. We demonstrate that a STM map can be used with sensors that generate point measurements, such as light detection and ranging (LiDAR) sensors and stereo cameras. We show that a STM map is a more accurate model than the only comparable online surface mapping technique$\unicode{x2014}$a standard elevation map$\unicode{x2014}$and we also provide qualitative results on practical datasets.
The 60-micron extragalactic background radiation intensity, dust-enshrouded AGNs and the assembly of groups and clusters of galaxies

description: Submillimetre observations reveal a cosmologically significant population of high-redshift dust-enshrouded galaxies. The form of evolution inferred for this population can be reconciled easily with COBE FIRAS and DIRBE measurements of the cosmic background radiation (CBR) at wavelengths >100 microns. At shorter wavelengths, however, the 60-micron CBR intensity reported by Finkbeiner et al. is less easily accounted for. Lagache et al. have proposed that this excess CBR emission is a warm Galactic component, and the detection of the highest-energy gamma-rays from blazars limits the CBR intensity at these wavelengths, but here we investigate sources of this excess CBR emission, assuming that it has a genuine extragalactic origin. We propose and test three explanations, each involving additional populations not readily detected in existing submm-wave surveys. First, dust-enshrouded galaxies with hot dust temperatures, perhaps dust-enshrouded, Compton-thick AGN as suggested by recent deep Chandra surveys. Secondly, a population of relatively low-redshift dusty galaxies with SEDs more typical of the existing submm-selected galaxies, which could plausibly be associated with the assembly of groups and clusters of galaxies. Thirdly, a population of low-luminosity, cool, quiescent spiral galaxies. Hot AGN and the assembly of groups can account for the excess 60-micron background. There are significant problems with the cluster assembly scenario, in which too many bright IRAS sources are predicted. Spiral galaxies have the wrong SEDs to account for the excess. Future wide-field far-IR surveys using SIRTF and Herschel will sample representative volumes of the distant Universe, allowing any hot population of dusty AGNs and forming groups to be detected.

Virgammaropsis

description: Virgammaropsis gen. nov.
 Type species. Virgammaropsis artemis sp. nov.
 Etymology. Latin: Virga meaning a rod (referring to the unexpanded pereopods), as a prefix to Gammaropsis, a related genus.
 Diagnosis. Head anteroventral margin weakly recessed, not extending behind posterior margin of eye; lateral cephalic lobes rounded. Mandible palp article 3 rod-shaped, parallel-sided. Antenna 1 peduncular article 1 longer than article 3; accessory flagellum distinct and multiarticulate. Coxae 1–2 without spines on distal margin. Coxa 1 not distally acute. Gnathopod 2 distinctly larger than gnathopod 1. Gnathopods 1–2 and pereopods 3–5 (probably also 6 and 7) with weakly expanded bases. Urosomites 1–2 without dorsolateral spines.
 Included species. Virgammaropsis artemis sp. nov.
 Remarks. Virgammaropsis differs from Gammaropsis Liljeborg, in its poorly recessed head, parallelsided article 3 of mandibular palp and weakly expanded pereopod bases. It resembles Falcigammaropsis Myers, 1995 from Papua New Guinea, in the parallel-sided article 3 of the mandibular palp, and in the form of the male gnathopod 2. It differs from that genus however in lacking an acute epistome, in the unexpanded basis of pereopod 5 (and probably also the unknown pereopods 6-7), and in the absence of spines on urosomite 1.

Non-oscillating solutions to uncoupled Ermakov systems and the semiclassical limit

description: The amplitude-phase formulation of the Schrödinger equation is investigated within the context of uncoupled Ermakov systems, whereby the amplitude function is given by the auxiliary nonlinear equation. The classical limit of the amplitude and phase functions is analyzed by setting up a semiclassical Ermakov system. In this limit, it is shown that classical quantities, such as the classical probability amplitude and the reduced action, are obtained only when the semiclassical amplitude and the accumulated phase are non-oscillating functions respectively of the space and energy variables. Conversely, among the infinitely many arbitrary exact quantum amplitude and phase functions corresponding to a given wavefunction, only the non-oscillating ones yield classical quantities in the limit $\hbar \to 0$.

description: We study ring-theoretic (in)finiteness properties -- such as \emph{Dedekind-finiteness} and \emph{proper infiniteness} -- of ultraproducts (and more generally, reduced products) of Banach algebras. Whilst we characterise when an ultraproduct has these ring-theoretic properties in terms of its underlying sequence of algebras, we find that, contrary to the $C^*$-algebraic setting, it is not true in general that an ultraproduct has a ring-theoretic finiteness property if and only if "ultrafilter many" of the underlying sequence of algebras have the same property. This might appear to violate the continuous model theoretic counterpart of Łoś's Theorem; the reason it does not is that for a general Banach algebra, the ring theoretic properties we consider cannot be verified by considering a bounded subset of the algebra of \emph{fixed} bound. For Banach algebras, we construct counter-examples to show, for example, that each component Banach algebra can fail to be Dedekind-finite while the ultraproduct is Dedekind-finite, and we explain why such a counter-example is not possible for $C^*$-algebras. Finally the related notion of having \textit{stable rank one} is also studied for ultraproducts.

description: The group-theoretical classification of states of identical particle pairs is presented. Then obtained states are coupled with those of an antiparticle to construct states of a three-particle system. Investigations are performed using products of irreducible projective representations of the 2D translation group. For a given BvK period N degeneracy of pair states is N, whereas three-particle states are N^2-fold degenerated. It has to be underlined that the case of even N is more complicated since pair states are labelled by four inequivalent irreducible projective representations. The problem of symmetry properties with respect to particles transposition is briefly discussed.

description: AbstractIntroduction: Autism Spectrum Disorders (ASD) are behaviourally defined syndromes where the etiology and pathophysiology are not very well understood. If the child has been diagnosed with autism, parents already face special behavioural challenges. What makes ASD even more difficult, are the many other medical health issues that often arise in this population.
The purpose of this article is to summarise the latest understanding of autism’s commonly associated physical and mental health conditions.Methods: An analysis of relevant literature, sources from the internet and published literature, personal experience and observations of the author.Recent findings: Autism is a disorder of the whole body. It is often in co-morbidity with: epilepsy, gastrointestinal disorders, neuro-inflammation and immunological disorders, asthma, eczema, sleep disturbances, eating and feeding disorders, food allergies, attention deficit and hyperactivity disorder (ADHD), headaches, anxiety disorders, bipolar disorder, depression, schizophrenia, obsessive-compulsive disorder, Fragile X syndrome, intellectual disability, nonverbal learning disorder, motor clumsiness, Tourette syndrome, sensory problems, tuberous sclerosis, oxidative stress, acquired mitochondrial dysfunction and metabolic abnormalities. Many of the issues outlined here can overlap each other.Conclusions:Improved understanding of the underlying pathology of ASD and associated conditions, and the development of a common purpose across multiple treating sites, can improve the consistent and coordinated healthcare of children with autism. There is need for the development of improved strategies for delivering effective health education and healthcare to this large population. Improving the ability of these persons to lead relatively independent lives has a great economic impact.Key words: autism spectrum disorders, health, condition, medical disorders

description: The origin of rovibrational H_2 emission in the central galaxies of cooling flow clusters is poorly understood. Here we address this issue using data from our near-infrared spectroscopic survey of 32 of the most line luminous such systems, presented in the companion paper by Edge et al. (2002). We consider excitation by X-rays from the surrounding intracluster medium, UV radiation from young stars, and shocks. The v=1-0 K-band lines with upper levels within 10^4 K of the ground state appear to be mostly thermalised (implying gas densities above ~10^5 cm^-3), with excitation temperatures typically exceeding 2000K, as found earlier by Jaffe, Bremer and van der Werf (2001). Together with the lack of strong v=2-0 lines in the H-band, this rules out UV fluorescence. Using the CLOUDY photoionisation code, we deduce that the H_2 lines can originate in a population of dense clouds, exposed to the same hot (T~50000K) stellar continuum as the lower density gas which produces the bulk of the forbidden optical line emission in the H-alpha luminous systems. This dense gas may be in the form of self-gravitating clouds deposited directly by the cooling flow, or may instead be produced in the high-pressure zones behind strong shocks. Furthermore, the shocked gas is likely to be gravitationally unstable, so collisions between the larger clouds may lead to the formation of globular clusters.

Subjects: subject: Instrumentation and Detectors (physics.ins-det)

description: A closed-form approximate expression is presented for the short time-frame development of silicon diode sensor signals in the context of high frame-rate detection of incident X-ray fluxes, in the limit that the X-ray absorption profile generates a longitudinally-uniform distribution of electron-hole pairs in the detector bulk. The expression represents the immediate time development of signals from diode sensors both with (LGAD) and without (PIN) gain, and presents a temporal scale associated with the onset of gain. Principles limiting the detection frame rate in the presence of electronic readout noise are discussed. Making use of an elemental simulation, the relative advantage of LGAD vs. PIN diode sensors is explored as a function of the effective electronic collection time. It is found that for an idealized LGAD sensor with a gain of 30, the gain provided by impact ionization yields an advantage relative to PIN diode sensors for frame rates as high as 10 GHz.

description: This article provides a theoretical model analyzing
wholesale pricing tariffs set by a monopolistic manufacturer for its
branded product that is sold to final customers by a monopolistic
retailer. The bargaining power of the downstream retailer is
strengthened by offering also a vertically differentiated private label
product whose production costs are known only incompletely to the
upstream manufacturer. The model shows that the manufacturer
can avoid double marginalization and implement the full information
outcome by combining a quantity discount with a market-share
discount where only a retailer with a strong private label retroactively
receives an allowance. Under these circumstances it is unprofitable
for the manufacturer to impose exclusive dealing on the retailer.

description: La présente thèse analyse deux romans et un essai de Mudimbe, dont l’œuvre exploite les enjeux de l’héritage colonial sur la conscience de l’intellectuel africain. Composé de romans sous la forme d’un monologue, notre corpus présente un « Je » (ancien colonisé) qui met en procès un « Autre ». Si cet « Autre » peut prendre plusieurs formes (le colonisateur, l’Occident, la femme occidentale, le missionnaire, et même l’Afrique), il reste que les rapports que le sujet postcolonial entretient avec ces différentes formes d’altérité ont en commun d’être marqués négativement. Le travail consiste à déterminer ce qui préside à ces rapports négatifs à l’Autre, rendant toute relation intersubjective presque impossible. L’hypothèse principale est que l’expérience coloniale serait à l’origine du déséquilibre du « je », lequel impacte sur la relation à l’Autre. Cependant, l’analyse montre qu’il est plus approprié de dire que le rapport à l’Autre est biaisé par deux déterminismes : l’histoire coloniale et le déterminisme social. Entre les eaux représente l’Autre par le christianisme ou le marxisme et L’Écart par l’histoire ou la psychanalyse, L’Autre face du royaume (essai) le représente par l’ethnologie, science coloniale. Toutefois, après avoir essayé de prendre ses distances avec ce qui représente l’Occident, sans vraiment y parvenir, le sujet postcolonial déroute le lecteur en refusant d’embrasser son Afrique. Au final, le sujet postcolonial, loin d’idéaliser l’Afrique ou d’en faire un paradis à retrouver, ou de se confondre au maître occidental, ne renie ni l’un ni l’autre. Il ouvre ainsi la voie à une identité hybride.

description: This research provides a qualitative and empirical investigation of the microeconomic causes and impacts of remittances in Egypt. We use data from a field study, involving interviews of 304 remittance-receiving families across 16 Egyptian governorates during May 2015–May 2016. Our Ordinary Least Square (OLS) and Tobit regressions show that the duration of migration, migrant’s age, household income, and household head’s job are the most important predictors of the level of remittances. The first three variables induce the value of received remittances, while the final variable, household head’s job, acts to the contrary and reduces remittances. In terms of remittances allocation, everyday expenses and real estate investments absorb the vast majority of channeled remittances. Most of the respondents (85%) do not invest remittances, and those who invest remittances mainly reside in Upper and Lower Egypt due to the low living costs in these regions.

description: We present here algorithmic cooling (via polarization-heat-bath)- a powerful method for obtaining a large number of highly polarized spins in liquid nuclear-spin systems at finite temperature. Given that spin-half states represent (quantum) bits, algorithmic cooling cleans dirty bits beyond the Shannon's bound on data compression, by employing a set of rapidly thermal-relaxing bits. Such auxiliary bits could be implemented using spins that rapidly get into thermal equilibrium with the environment, e.g., electron spins. Cooling spins to a very low temperature without cooling the environment could lead to a breakthrough in nuclear magnetic resonance experiments, and our ``spin-refrigerating'' method suggests that this is possible. The scaling of NMR ensemble computers is probably the main obstacle to building useful quantum computing devices, and our spin-refrigerating method suggests that this problem can be resolved.

Starting with fully magnetised states, either in the $x$ or $z$ direction, we compute numerically the average quantities. They show similar behaviour to the homogeneous chain, that is an algebraic decay in time toward a stationary state. During the time evolution, the spatial correlations, measured from one end to the other of the chain, are building up and finally at long time they reach a size-dependent constant depending on the distance from criticality. Analytical arguments are given which support the numerical results.

description: Face recognition is a mainstream biometric authentication method. However, vulnerability to presentation attacks (a.k.a spoofing) limits its usability in unsupervised applications. Even though there are many methods available for tackling presentation attacks (PA), most of them fail to detect sophisticated attacks such as silicone masks. As the quality of presentation attack instruments improves over time, achieving reliable PA detection with visual spectra alone remains very challenging. We argue that analysis in multiple channels might help to address this issue. In this context, we propose a multi-channel Convolutional Neural Network based approach for presentation attack detection (PAD). We also introduce the new Wide Multi-Channel presentation Attack (WMCA) database for face PAD which contains a wide variety of 2D and 3D presentation attacks for both impersonation and obfuscation attacks. Data from different channels such as color, depth, near-infrared and thermal are available to advance the research in face PAD. The proposed method was compared with feature-based approaches and found to outperform the baselines achieving an ACER of 0.3% on the introduced dataset. The database and the software to reproduce the results are made available publicly.

strategy choice; evolution;
cooperation

description: A recent series of papers has introduced a fresh perspective on the
problem of the evolution of human cooperation by suggesting an
amendment to the concept of cooperation itself: instead of thinking
of cooperation as playing a particular strategy in a given game, usually
C in the prisoner's dilemma, we could also think of cooperation
as collaboration, i.e. as coalitional strategy choice, such as jointly
switching from (D;D) to (C;C). The present paper complements
previous work on collaboration by expanding on its genericity while
relaxing the assumption that collaborators are able to perfectly identify
their own kind. Conditions for the evolutionary viability of such
collaboration under fairly undemanding assumptions about population
and interaction structure are derived. Doing so, this paper
shows that collaboration is an adaptive principle of strategy choice
in a broad range of niches, i.e., stochastic mixtures of games.

description: Firms sometimes violate competition laws by agreeing on increases of list prices. The economic effects of such list price collusion are far from clear because the cartel firms might deviate secretly from the elevated prices by granting their customers discounts. This article presents case evidence suggesting that agreements on list prices are not infrequently observed in cartel cases. It also reviews theoretical, empirical, and experimental literature in economics showing under what conditions such list price collusion causes the discounted transaction prices to rise. This is relevant for competition authorities in developing a theory of harm when prosecuting cartels, and also for the customers of the cartel firms when suing the conspirators for the repayment of damages.

Family and Identity in the book of Judges

description: The importance of the family in ancient Near Eastern society is so frequently recognized that it has become a truism. It is therefore surprising that in a work of identity-making such as the Bible, the influence of family on the texts’ formation has been under studied. Such an omission may be because the discussion on family in the Bible has largely concentrated upon reconstructing day-to-day life as background to our reading. Scholars have not seen family loyalty as an essential component in the narratives’ meaningfulness. In my dissertation, I examine family and identity in the Book of Judges. I argue that the family is the dominant locus of identity for people throughout the first millennium BCE and that Judges’ social communication depends upon acknowledging this dynamic. The meaning of the local folklore gathered together in Judges relies upon an appreciation of the values held by the society from which it comes and distinguishes this core material from the editorial framework. This perspectival dichotomy also raises questions about the book’s redactional methodology. Identity is revealed through socio-relational dynamics; hence, my thesis takes a social-scientific approach to the texts. Following an introduction, the first chapter discusses family and identity with particular reference to the localized structures of first-millennium BCE Palestine. The next four chapters present texts from Judges in which I employ four socio-anthropological theories. I begin with the tale of Jael and Sisera in Judg 4 and 5, to which I apply the concept of social space. I then compare the stories of Abimelech in Judg 9 and Jephthah in Judg 11 in light of ascribed social status. The wedding of Samson in Judg 14 forms the third study for which endogamy and the socio-economic autonomy of the household are relevant theories and I end by discussing hospitality and social distance in the eventful journey of the Levite in Judg 19. I conclude that the ‘nationalizing’ of these folktales by the editorial frame must nevertheless respect their familial perspective to maximize the success of Israel’s identity-making.

description: In this paper, we investigate the finiteness of the Higgs effective potential in an ${\rm SU}(\mathcal N)$ Gauge-Higgs Unification (GHU) model defined on ${\bf M}^4\times S^1$. We obtain the Higgs effective potential at the two-loop level and find that it is finite. We also discuss that the Higgs effective potential is generically divergent for three- or higher-loop levels. As an example, we consider an ${\rm SU}(\mathcal N)$ gauge theory on ${\bf M}^5\times S^1$, where the one-loop corrections to the four-Fermi operators are divergent. We find that the Higgs effective potential depends on their counter terms at the three-loop level.

description: The cross-country interbank market in the euro area was a crucial transmission channel of financial stress. By using a two-country DSGE model of a financially heterogeneous monetary union where banks in one country lend funds to their foreign counterparts, I examine its role as shock amplifer and the implications for unconventional policy interventions Using the international interbank market to pool and insure against shocks is not neutral, the resulting spillovers rather act as shock multipliers on union output. Country-specific unconventional policies of direct lending to firms seem to be the most e¤ective interventions in terms of union and relative output stabilization. The higher the size of the interbank market, the more effective are these policies in terms of union stabilization. The effectiveness of interventions in the interbank market seems to be very sensitive to the type of shock and the interbank market size. Hence, the central bank should rather shy away from this policy as it is only useful under specific circumstances.
Dust depletion and abundance pattern in damped Lyman-alpha systems: a sample of Mn and Ti abundances at z<2.2

description: We analyse a sample of 24 damped Lyman-alpha (DLA)/moderate DLA systems at 0.3~-0.5, the intrinsic (dust-corrected) abundance pattern of Si, Ti, Cr and Mn in DLA absorbers closely follows the trends observed in Galactic stars and these absorbers should thus have a chemical evolution similar to that of our Galaxy. At lower metallicity, some absorbers do follow the trends present in Galactic stars but a substantial fraction of them have elemental ratios (in particular [Si/Fe]dc and [Mn/Fe]dc) closer to the solar values than Galactic stars. This could be explained by a larger contribution of type Ia supernovae to the chemical enrichment of these DLA absorbers than in Galactic stars of similar metallicity. This metal-poor DLA absorber population could trace HI-rich dwarf galaxies. (Abridged)

B=4N Nuclei in the Skyrme Model

description: The Skyrme model enables us to approximate nuclei via topological solitons known as Skyrmions. The B = 4 Skyrmion is of particular importance as its symmetry and stability means that multiple B = 4 Skyrmions can combine with each other to form larger B = 4N Skyrmions. In this thesis we investigate the properties of these B = 4N Skyrmions and compare them with results found in the wider nuclear physics community. We go beyond rigid body quantization and develop a formalism of using vibrational quantisation to generate the energy spectrum of the Oxygen−16 nucleus. The Oxygen−16 nucleus is treated as an arrangement of four B = 4 Skyrmions, whose dynamics enable us to create a 2−dimensional manifold of B = 16 configurations. We solve the Schrödinger equation on this manifold and discover new states previously not found in the B = 16 sector of the Skyrme model. We compare these states with those found experimentally and find that there is a excellent it to the energy spectrum. In order to apply vibrational quantization to a wider range of nuclei we create a novel approximation for Skyrmions and the interactions between them. By generating Skyrmions with Gaussian sources we find analytic expressions for the pion fields and interaction energies of Skyrmions, with particular focus on the B = 1 and B = 4 Skyrmions, and show how this could be applied to vibrational quantization and the clustering of B = 4 Skyrmions. B = 4N nuclei are the only nuclei with zero spin and isospin, which means that their electric charge density is proportional to their baryon density. This simplification makes these nuclei particularly susceptible to investigation via electron scattering. We develop a classical averaging method to calculate the Patterson function and the form factor for a B = 4N nucleus and make comparisons with experimental data. We also discover a way of using the baryon density directly to approximate the locations of zeroes and stationary points of the form factor.

description: We explore several models which might be proposed to explain recent possible detections of high-energy (TeV) gamma rays in association with low-energy gamma-ray bursts (GRBs). Likely values (and/or upper limits) for the source energies in low- and high-energy gamma rays and hadrons are deduced for the burst sources associated with possible TeV gamma-ray detections by the Project GRAND array. Possible spectra for energetic gammas are deduced for three models: 1) inverse-Compton scattering of ambient photons from relativistic electrons; 2) proton-synchrotron emission; and 3) inelastic scattering of relativistic protons from ambient photons creating high-energy neutral pions, which decay into high-energy photons. These models rely on some basic assumptions about the GRB properties, e.g. that: the low- and high-energy gamma rays are produced at the same location; the time variability of the high-energy component can be estimated from the FWHM of the highest peak in the low-energy gamma ray light curve; and the variability-luminosity relation of Fenimore & Ramirez-Ruiz (2000) gives a reliable estimate of the redshifts of these bursts. We also explore the impact of each of these assumptions upon our models. We conclude that the energetic requirements are difficult to satisfy for any of these models unless, perhaps, either the photon beaming angle is much narrower for the high-energy component than for the low-energy GRB or the bursts occur at very low redshifts (z<0.01). Nevertheless, we find that the energetic requirements are most easily satisfied if TeV gamma rays are produced predominantly by inverse-Compton scattering with a magnetic field strength well below equipartition or by proton-synchrotron emission with a magnetic field strength near equipartition.
