A COMPACT QUALITATIVE UNCERTAINTY PRINCIPLE FOR SOME NONUNIMODULAR GROUPS
Authors: NASSERDDINE WASSIM 
Published: November 2018

Let $G$ be a separable locally compact group with type $I$ left regular representation, $\widehat{G}$ its dual, $A(G)$ its Fourier algebra and $f\in A(G)$ with compact support. If $G=\mathbb{R}$ and the Fourier transform of $f$ is compactly supported, then, by a classical Paley–Wiener theorem, $f=0$. There are extensions of this theorem for abelian and some unimodular groups. In this paper, we prove that if $G$ has no (nonempty) open compact subsets, $\hat{f}$, the regularised Fourier cotransform of $f$, is compactly supported and $\text{Im}\,\hat{f}$ is finite dimensional, then $f=0$. In connection with this result, we characterise locally compact abelian groups whose identity components are noncompact.
Homer, The Archaeology of Crete and the ‘Tomb of Meriones’ at Knossos
Authors: Kotsonas Antonis 
Published: November 2018

AbstractHomeric archaeology long dominated the study of early Greece, but new approaches have recently revolutionized the field. Drawing from these approaches, I offer a regional and diachronic analysis of Homeric stories about Crete, an assessment of the reception of these stories by the island's inhabitants throughout antiquity and an account of their impact on medieval to modern literature and art. I find that Cretan interest in Homer peaks in the Hellenistic period, but also argue for the much earlier familiarity of some Cretans with stories that underlie the Homeric epics. This argument relies on an analysis of the archaeological assemblage of a Knossian tomb of the 11th century BC, which includes a range of arms that is exceptional for both Aegean archaeology and the Homeric epics. In the epics, this equipment is carried by the Knossian hero Meriones, whose poetic persona can be traced back to the Late Bronze Age on philological and linguistic grounds. Based on this, and on current understandings of performance at death, I argue that the Knossian burial assemblage was staged to reference the persona of Meriones, therefore suggesting the familiarity of some Cretans with early stories that eventually filtered into the Homeric epics.
In the Shadow of Phoenicia: North Syria and ‘Palestinian Syria’ in Herodotus
Authors: Sullivan Benjamin M. 
Published: November 2018

AbstractScrutiny of Herodotus’ ethnographic accounts of northern Syria and the region he calls ‘Palestinian Syria’ reveals oddities and inconsistencies. Here it is argued that such problems may be resolved if a fundamental fact is recognized: the enormous early literary prestige of the Phoenicians has obscured the historical roles of these other peoples in the Histories. The character and extent of this process, specifically as it bears on Syria-Palestine during Iron Age II, is analysed here. It is hoped that a new appreciation of the Syrians as an ethnicity may be gained as a result. It is suggested as well that for important historical problems researchers should ascertain whether Herodotus is not actually talking about Syrians when he discusses Phoenicians.
Wave-Like Commentaries: The Structure and Philosophical Orientation of Middle Platonist Commentaries
Authors: Petrucci Federico M. 
Published: November 2018

AbstractScholars remain far from reaching agreement about the structure of Middle Platonist commentaries on Plato's dialogues: some take them to have been running line-by-line commentaries, while others believe that Middle Platonist commentaries were mainly specialist works. In this paper I propose a fresh and comprehensive analysis of extant sources in order to show that both views, while shedding light on important features of this literary genre in Middle Platonism, should be supplemented in order to draw a more complex picture. Extant sources suggest that the Middle Platonist commentaries were characterized by a set of features which shaped a specific conception of the literary genre: they were lemmatic and followed the development of a dialogue in its progression, yet at the same time they applied a thematic focus and hence admitted a substantial degree of selectivity.
Success in a Fontan pregnancy: how important is ventricular function?
Authors: Ordonez M. Victoria , Trinder Johanna , Curtis Stephanie L. 
Published: November 2018

AbstractThe Fontan operation is a palliative surgical procedure for patients whose hearts cannot support a biventricular circulation. The haemodynamic changes that occur in pregnancy are particularly challenging for Fontan patients and the outcomes are variable. We present a case where fetal outcome was particularly poor despite a lack of high risk features pre-pregnancy.

AbstractObjectives: A major challenge in cognitive aging is differentiating preclinical disease-related cognitive decline from changes associated with normal aging. Neuropsychological test authors typically publish single time-point norms, referred to here as unconditional reference values. However, detecting significant change requires longitudinal, or conditional reference values, created by modeling cognition as a function of prior performance. Our objectives were to create, depict, and examine preliminary validity of unconditional and conditional reference values for ages 40–75 years on neuropsychological tests. Method: We used quantile regression to create growth-curve–like models of performance on tests of memory and executive function using participants from the Wisconsin Registry for Alzheimer’s Prevention. Unconditional and conditional models accounted for age, sex, education, and verbal ability/literacy; conditional models also included past performance on and number of prior exposures to the test. Models were then used to estimate individuals’ unconditional and conditional percentile ranks for each test. We examined how low performance on each test (operationalized as <7th percentile) related to consensus-conference–determined cognitive statuses and subjective impairment. Results: Participants with low performance were more likely to receive an abnormal cognitive diagnosis at the current visit (but not later visits). Low performance was also linked to subjective and informant reports of worsening memory function. Conclusions: The percentile-based methods and single-test results described here show potential for detecting troublesome within-person cognitive change. Development of reference values for additional cognitive measures, investigation of alternative thresholds for abnormality (including multi-test criteria), and validation in samples with more clinical endpoints are needed.

Delay discounting and its association with food purchasing considerations and food availability in the home in south-east Alabama, USA
Authors: Garza Kimberly B , Datubo-Brown Christiana , Gaillard Philippe , Jeminiwa Ruth 
Published: November 2018

AbstractObjectiveCertain factors, such as food quality, label content and grocery characteristics, may be considered when purchasing foods. Food availability in the home has been shown to influence dietary behaviours, also associated with delay discounting (DD). The present study sought to characterize the relationships between DD, food purchasing considerations and healthfulness of foods in the home.DesignA cross-sectional, online survey of adults (n 477) was conducted with the following measures: DD, consideration of food quality (nutrition, taste) and grocery characteristics (price, ease of preparation, shelf-life) while shopping, use of food labels and food availability in the home. DD was assessed by the area under the delay discounting curve (AUC) using a binary choice task. Greater AUC reflects lower DD. Structural equation modelling was used to allow AUC to simultaneously predict purchasing considerations and foods in the home.SettingOnline survey.ParticipantsAdult employees in south-east Alabama, USA.ResultsDD was negatively associated with food label use and emphasis on food quality when shopping (P<0·001). In the final model, DD was associated with availability of healthful foods in the home and emphasis on food quality and grocery characteristics. About 33 % of the variance in shopping behaviours, 5 % in food label use, 7 % in availability of healthful foods and 4 % in availability of unhealthful foods was explained by DD.ConclusionsIndividuals with lower DD appear to be more thoughtful in making food purchasing decisions and have healthful foods available in the home more frequently than individuals with higher DD.
The Dynamic History of 220 Million Years of Subduction Below Mexico: A Correlation Between Slab Geometry and Overriding Plate Deformation Based on Geology, Paleomagnetism, and Seismic Tomography

Published: November 2018

AbstractGlobal tectonic reconstructions of pre‐Cenozoic plate motions rely primarily on paleomagnetic and geological data from the continents, and uncertainties increase significantly with deepening geological time. In attempting to improve such deep‐time plate kinematic reconstructions, restoring lost oceanic plates through the use of geological and seismic tomographical evidence for past subduction is key. The North American Cordillera holds a record of subduction of oceanic plates that composed the northeastern Panthalassa Ocean, the large oceanic realm surrounding Pangea in Mesozoic times. Here we present new paleomagnetic data from subduction‐related rock assemblages of the Vizcaíno Peninsula of Baja California, Mexico, which yield a paleolatitudinal plate motion history equal to that of the North American continent since Late Triassic time. This indicates that the basement rocks of the Vizcaíno Peninsula formed in the forearc of the North American Plate, adjacent to long‐lived eastward dipping subduction at the southern part of the western North American continental margin. Tomographic images confirm long‐lived, uninterrupted eastward subduction. We correlate episodes of overriding plate shortening and extension to flat and steep segments of the imaged slab. By integrating paleomagnetic, geological, and tomographic evidence, we provide a first‐order model that reconciles absolute North American plate motion and the deformation history of Mexico since Late Triassic time with modern slab structure.

Published: November 2018

AbstractA mobile Shared Mobile Atmospheric Research and Teaching (SMART) radar was deployed in Hurricane Harvey and coordinated with the Corpus Christi, TX, WSR‐88D radar to retrieve airflow during landfall. Aerodynamic surface roughness estimates and a logarithmic wind profile assumption were used to project the 500‐m radar‐derived maximum wind field to near the surface. The logarithmic wind assumption was justified using radiosonde soundings taken within the storm, while the radar wind estimates were validated against an array of StickNets. For the data examined here, the radar projections had root‐mean‐squared error of 3.9 m/s and a high bias of 2.3 m/s. Mesovorticies in Harvey's eyewall produced the strongest radar‐observed winds. Given the wind analysis, Harvey was, at most, a Category 3 hurricane (50–58 m/s sustained winds) at landfall. This study demonstrates the utility of integrated remote and in situ observations in deriving spatiotemporal maps of wind maxima during hurricane landfalls.
Estimating the Rate of Cessation of Magnetospheric Activity in AMPERE Field‐Aligned Currents
Authors: Moretto T. , Hesse M. , Vennerstrøm S. , Tenfjord P. 
Published: November 2018

AbstractThe decay of magnetospheric activity when driving is turned off (to a minimum) was measured in total field‐aligned current estimates from the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) project. Events of distinct northward turnings of the interplanetary magnetic field were identified, with prolonged periods of stable southward driving conditions followed by northward interplanetary magnetic field conditions. All but 4 of 43 identified events exhibit a well‐defined exponential decay in the total hemispheric field‐aligned current following the northward turning. A superposed epoch analysis yields a generic decay constant of 0.9, corresponding to an e‐folding time of 1.1 hr. A statistical analysis of the ensemble of events also reveals a seasonal variation in the decay parameter with faster decay observed in the winter than in the summer hemisphere. This result can be understood in terms of stronger/weaker line tying of the ionospheric foot points of magnetospheric field lines for higher/lower conductivity.
The Role of Shear Stress in Fault Healing and Frictional Aging
Authors: Ryan Kerry L. , Rivière Jacques , Marone Chris 
Published: November 2018

AbstractThe seismic cycle involves repeated failure and strength recovery of tectonic faults, known as fault healing. In Earth's crust, where fault strength is dominated by friction, frictional healing is the primary agent of fault healing. Laboratory studies document the role of contact aging and cementation as key mechanisms of frictional healing; however, the role of shear stress is not well understood. We describe a laboratory study of frictional healing as a function of shear stress for bare granite surfaces and simulated fault gouge composed of Westerly granite and quartz. Faults are sheared at normal stresses of 5–25 MPa, 100% relative humidity and room temperature. We quantify frictional healing in slide‐hold‐slide tests for shear stresses from 0 to the sliding friction value and monitor the amplitude of elastic waves propagating across the fault zone. Healing of gouge shows a strong negative dependence on shear stress, whereas healing of bare surfaces does not vary systematically with shear stress. In gouge, frictional healing involves shear stress‐dependent compaction and particle rearrangement, while for bare surfaces frictional strength is derived primarily from contact area evolution. The magnitude of compaction in gouge varies with shear stress, which explains the dependence of healing on shear stress. Elastic wave amplitude increases with hold time and varies inversely with shear stress, consistent with fault zone compaction, shear dilatancy, and their impact on strength evolution and healing. Fault zone compaction during shear unloading and reloading operates with contact aging to dictate frictional healing and fault restrengthening following shear failure.
Prognostic Power of Extreme Rainfall Scaling Formulas Across Space and Time Scales
Authors: Fildier B. , Parishani H. , Collins W. D. 
Published: November 2018

AbstractSome studies documenting changes in extreme precipitation use scaling formulas to approximate the large percentiles of the rainfall distribution from average dynamical and thermodynamical variables, called predictors. Here we instead assess the performance of these formulas as approximations to the rain rates in individual events. We evaluate the accuracies of the scaling relationships as functions of spatial and temporal scales by analyzing tropical rainfall in a superparameterized model. Relationships using full vertical profiles of the predictors are more accurate than those using their values at specific vertical levels because they better characterize the specific dynamics of each event. Both types of scaling relationships perform well over a range of length scales from 200 to 2,000 km and time scales from an hour to a week, and their precision is higher in the case of simulations with superparameterization than with parameterized convection. Uncertainties emerging from the local use of the scaling relationships suggest that they may only characterize the intensification of individual extremes for a warming of 4–5 K or larger. Finally, we argue that these formulas can be used to reconstruct the tail of the rainfall distribution directly from its predictors without prior information on P. While scalings have been used as diagnostic equations conditioned on the occurrence of extreme rainfall, they are actually able to mimic the prognostic behavior of climate model parameterizations on a variety of scales when estimating the intensity, frequency, and spatial patterns of extremes.

AbstractThis paper describes the dynamic characteristics of ionospheric plasma turbulences excited by high‐power high‐frequency radio waves during ionospheric modification experiments at the High‐frequency Active Auroral Research Program heating facility, Gakona, Alaska. The data come from measurements of high‐frequency‐induced stimulated electromagnetic emission (SEE) and anomalous absorption of test radiowaves. In addition to quasi‐continuous pump (QCP) waves that excite the “standard” SEE, short pulses of diagnostic waves at frequencies shifted from the QCP frequency have been injected to generate diagnostic SEE. This experimental setup allowed us to study the spectra and damping rates of the plasma waves related to both diagnostic and QCP waves, as well as the QCP‐related small‐scale magnetic field‐aligned irregularities at different altitudes, ±25 km around the center of the heated volume. The results of numerical simulations of the upper hybrid‐related SEE and diagnostic SEE under a “double‐transformation” scheme with the use of an empirical model of the irregularities' spatial spectrum and its dynamics are in good agreement with the observations.

AbstractThe podocytes within the glomeruli of the kidney maintain the filtration barrier by forming interdigitating foot processes with intervening slit diaphragms, disruption in which results in proteinuria. Studies into human podocytopathies to date have employed primary or immortalised podocyte cell lines cultured in 2D. Here we compare 3D human glomeruli sieved from induced pluripotent stem cell-derived kidney organoids with conditionally immortalised human podocyte cell lines, revealing improved podocyte-specific gene expression, maintenance in vitro of polarised protein localisation and an improved glomerular basement membrane matrisome compared to 2D cultures. Organoid-derived glomeruli retain marker expression in culture for 96 h, proving amenable to toxicity screening. In addition, 3D organoid glomeruli from a congenital nephrotic syndrome patient with compound heterozygous NPHS1 mutations reveal reduced protein levels of both NEPHRIN and PODOCIN. Hence, human iPSC-derived organoid glomeruli represent an accessible approach to the in vitro modelling of human podocytopathies and screening for podocyte toxicity.
Screw dislocation structure and mobility in body centered cubic Fe predicted by a Gaussian Approximation Potential

Published: November 2018

AbstractThe plastic flow behavior of bcc transition metals up to moderate temperatures is dominated by the thermally activated glide of screw dislocations, which in turn is determined by the atomic-scale screw dislocation core structure and the associated kink-pair nucleation mechanism for glide. Modeling complex plasticity phenomena requires the simulation of many atoms and interacting dislocations and defects. These sizes are beyond the scope of first-principles methods and thus require empirical interatomic potentials. Especially for the technological important case of bcc Fe, existing empirical interatomic potentials yield spurious behavior. Here, the structure and motion of the screw dislocations in Fe are studied using a new Gaussian Approximation Potential (GAP) for bcc Fe, which has been shown to reproduce the potential energy surface predicted by density-functional theory (DFT) and many associated properties. The Fe GAP predicts a compact, non-degenerate core structure, a single-hump Peierls potential, and glide on {110}, consistent with DFT results. The thermally activated motion at finite temperatures occurs by the expected kink-pair nucleation and propagation mechanism. The stress-dependent enthalpy barrier for screw motion, computed using the nudged-elastic-band method, follows closely a form predicted by standard theories with a zero-stress barrier of ~1 eV, close to the experimental value of 0.84 eV, and a Peierls stress of ~2 GPa consistent with DFT predictions of the Peierls potential.

AbstractThe construction of high capacity data sharing networks to support increasing government and commercial data exchange has highlighted a key roadblock: the content of existing Internet-connected information remains siloed due to a multiplicity of local languages and data dictionaries. This lack of a digital lingua franca is obvious in the domain of human food as materials travel from their wild or farm origin, through processing and distribution chains, to consumers. Well defined, hierarchical vocabulary, connected with logical relationships—in other words, an ontology—is urgently needed to help tackle data harmonization problems that span the domains of food security, safety, quality, production, distribution, and consumer health and convenience. FoodOn (http://foodon.org) is a consortium-driven project to build a comprehensive and easily accessible global farm-to-fork ontology about food, that accurately and consistently describes foods commonly known in cultures from around the world. FoodOn addresses food product terminology gaps and supports food traceability. Focusing on human and domesticated animal food description, FoodOn contains animal and plant food sources, food categories and products, and other facets like preservation processes, contact surfaces, and packaging. Much of FoodOn’s vocabulary comes from transforming LanguaL, a mature and popular food indexing thesaurus, into a World Wide Web Consortium (W3C) OWL Web Ontology Language-formatted vocabulary that provides system interoperability, quality control, and software-driven intelligence. FoodOn compliments other technologies facilitating food traceability, which is becoming critical in this age of increasing globalization of food networks.
