description: We show that the six-dimensional uplift of the five-dimensional Near-Horizon-Extremal-Kerr (NHEK) spacetime can be obtained from an AdS_3 X S^3 solution by a sequence of supergravity - but not string theory - dualities. We present three ways of viewing these pseudo-dualities: as a series of transformations in the STU model, as a combination of Melvin twists and T-dualities and, finally, as a sequence of two generalized spectral flows and a coordinate transformation. We then use these to find an infinite family of asymptotically flat embeddings of NHEK spacetimes in string theory, parameterized by the arbitrary values of the moduli at infinity. Our construction reveals the existence of non-perturbative deformations of asymptotically-NHEK spacetimes, which correspond to the bubbling of nontrivial cycles wrapped by flux, and paves the way for finding a microscopic field theory dual to NHEK which involves Melvin twists of the D1-D5 gauge theory. Our analysis also clarifies the meaning of the generalized spectral flow solution-generating techniques that have been recently employed in the literature.

description: The magnetic behaviour of a disordered ferrimagnetic system Ap B1-p where both A and B represent the magnetic atoms with respective spin SA = 1/2 and SB = 1 in presence of high magnetic field is treated theoretically.Assuming the magnetic interaction can be described through Ising Hamiltonian the approximate free energy is obtained using the cluster-variational method. The field dependence of the magnetization is then obtained for different concentration p and exchange parameters (JAA, JBB and JAB). For p = 0.5,the magnetization M in ferrimagnetic state and in absence of compensation temperature Tcm vanishes at TC.Field induced reversal of M is found at switching temperature TS (

Governance

description: At the end of 2022, an author group led by the EOSC Association Task Force on FAIR Metrics and Data Quality published ‘Community-driven governance of FAIRness assessment: an open issue, an open discussion’ which, as the title suggests, aims to foster an open debate with the community around FAIRness governance and the mechanism(s) that could be used to implement it. The FAIR-IMPACT project is keen to take part in this open community discussion, as many tasks and activities in this project focus on advancing FAIR assessment metrics and tools in various ways. FAIR-IMPACT supports the implementation of FAIR-enabling practices, tools and services across scientific communities at a European, national and institutional level. One of our overall objectives is to expand FAIRness assessment metrics and tools to cover a broader scope of digital objects (data, software, semantic objects) as well as to add community-specificity to the metrics and tools. Working so closely with FAIR assessment metrics and tools, as well as being involved in the projects’ synchronisation efforts to better harmonise the current landscape, we acknowledge and experience the complications that the lack of governance entails for the field of FAIR and assessment. This document presents our thoughts and views on the whitepaper and is our public effort for participation in the community discussion.

description: A comprehensive review of the literature was performed on migration of substances from packaging materials into dry foods, specifically those with surfaces containing no free fats or oils. Historically, migration from food packaging to dry foods has been assumed to be minimal. However, several recent publications have reported concentrations of migrants into dry foods that are substantially higher than anticipated. The goal of this review is to provide a comprehensive summary of recent studies that examined migration to dry foods or dry food simulants, observe and assess common migrants, and report the highest migration values. Focusing on the packaging materials and migrants that exhibit the highest migration values, this review divided the studies into two categories: 1) analysis of food products in commercial packaging taken directly from grocery store shelves, and 2) analysis of food products and food simulants in contact with packaging or other material fortified with known quantities of a migrant. Discussions include the examination of migration testing methods, viability of different food simulants, and variables that affect migration behaviour. These include the physicochemical properties of both the migrant and food (i.e. volatility, molecular size, structure, food composition and particle size) and factors pertaining to the packaging material and the environment (i.e. temperature, humidity, and the presence of a secondary barrier). Information gaps and remaining questions are also identified and discussed.

Development of British Columbia wood pellet life cycle inventory and its utilization in the evaluation of domestic pellet applications
Creators: name: Pa, Ann An
Publisher: name: University of British Columbia
Year: 2010

description: An in-house life cycle inventory (LCI) database for British Columbia (BC) wood pellets is established. The LCI database is used to compare the performance of BC pellets exported to Rotterdam and BC pellets staying within BC in terms of energy penalty, percent of fossil fuel content in pellets arriving destination, and impacts (human health, ecosystem quality and climate change) by performing life cycle impact assessment (LCIA) in a commercial LCA software. The database is also utilized to assess two domestic applications of BC wood pellets: replacing natural gas combustion in UBC district heating facility with wood waste or wood pellet gasification, and replacing firewood in BC residential heating with wood pellets. Overall, the analysis indicated that marine transportation is responsible for over 40% of the life cycle energy consumption and more than 50% of each of the impact categories investigated. The energy penalty and fossil fuel content of exported pellets are roughly 50% and 90% higher than that of the non-exported pellets. For the district heating case study, the base scenario performs much better than all biomass gasification systems in all impact categories other than climate change. The saving in GHG emission is approximately 81% if woody biomasses are utilized. Over the entire life cycle, controlled wood waste gasification system performs better than controlled wood pellet gasification system due to the extra processing required for wood pellets. However, when looking at the health impact associated with stack emissions only, controlled wood pellet gasification would raise the health impact by 12% from the base case while controlled wood waste gasification would raise the impact by 133%. By switching from firewood to wood pellets for BC residential heating, the primary energy consumption and impacts on human health, ecosystem quality and climate change can be reduced by 34%, 95%, 27% and 17%, respectively. Over 90% reduction in external costs can also be achieved. In terms of economic viability, when bulk pellets are to be utilized, switching from firewood to pellet units would be reasonable as long as the unit to be replaced is not a fireplace insert.

description: We study the integrability in the Liouville sense of natural Hamiltonian systems with a homogeneous rational potential $V(\vq)$. Strong necessary conditions for the integrability of such systems were obtained by an analysis of differential Galois group of variational equations along certain particular solutions. These conditions have the form of arithmetic restrictions putted on eigenvalues of Hessian $V"(\vd)$ calculated at a non-zero solution $\vd$ of equation $\grad V(\vd)=\vd$. Such solutions are called proper Darboux points. It was recently proved that for generic polynomial homogeneous potentials there exist universal relations between eigenvalues of Hessians of the potential taken at all proper Darboux points. The question about the existence of such relations for rational potentials seems to be hard. One of the reason of this fact is the presence of indeterminacy points of the potential and its gradient. Nevertheless, for two degrees of freedom we prove that such relation exists. This result is important because it allows to show that the set of admissible values for eigenvalues of Hessian at a proper Darboux point for potentials satisfying necessary conditions for the integrability is finite. In turn, it gives a tool for classification of integrable rational potentials. Also, quite recently, it was shoved that for polynomial homogeneous potentials additional necessary conditions for the integrability can be deduced from the existence of improper Darboux points, i.e., points $\vd$ which are non-zero solution of equation $\grad V(\vd)=\vzero$. These new conditions have also the form of arithmetic restrictions imposed on eigenvalues of $V"(\vd)$. In this paper we prove that for rational potentials improper Darboux points give the same necessary conditions for the integrability.

description: A molecular dynamics simulation-based study has been performed to examine the deformation behaviour of the predetermined parallel and perpendicular centreline cracks in CNTs embedded nanocrystalline aluminum (CNTs-NC Al) composite specimens under uniaxial loading. The hybrid potential (i.e. EAM, AIREBO, and LJ) method is adopted for carrying out the tensile deformation at three different temperatures (such as 10 K, 300 K, and 653 K). The mechanical properties are evaluated for both cases of parallel and perpendicular cracks of NC Al and CNTs-NC Al specimens. (30,30) CNT-NC Al specimen has shown superior fracture strain and ultimate tensile strength (UTS) at low temperature, whereas, higher fracture strain and lower UTS at high temperature than NC Al specimen. The mechanical properties of CNTs-NC Al nanocomposites are affected by the pre-existing crack and loading direction. The CNTs-NC Al nanocomposite specimens have exhibited the highest dislocation density compared to the NC Al specimen. The Shockley partial dislocations are a major driving factor for the parallel and perpendicular cracks of both (NC Al and CNTs-NC Al) specimens. The structural evolution and defect variation (such as stacking faults interaction with various dislocations, twin boundary, and grain boundary widening) has been elucidated during the tensile deformation of NC Al and CNT-NC Al nanocomposites.
Model Diagnostics meets Forecast Evaluation: Goodness-of-Fit, Calibration, and Related Topics

description: Principled forecast evaluation and model diagnostics are vital in fitting probabilistic models and forecasting outcomes of interest. A common principle is that fitted or predicted distributions ought to be calibrated, ideally in the sense that the outcome is indistinguishable from a random draw from the posited distribution. Much of this thesis is centered on calibration properties of various types of forecasts. In the first part of the thesis, a simple algorithm for exact multinomial goodness-of-fit tests is proposed. The algorithm computes exact $p$-values based on various test statistics, such as the log-likelihood ratio and Pearson's chi-square. A thorough analysis shows improvement on extant methods. However, the runtime of the algorithm grows exponentially in the number of categories and hence its use is limited. In the second part, a framework rooted in probability theory is developed, which gives rise to hierarchies of calibration, and applies to both predictive distributions and stand-alone point forecasts. Based on a general notion of conditional T-calibration, the thesis introduces population versions of T-reliability diagrams and revisits a score decomposition into measures of miscalibration, discrimination, and uncertainty. Stable and efficient estimators of T-reliability diagrams and score components arise via nonparametric isotonic regression and the pool-adjacent-violators algorithm. For in-sample model diagnostics, a universal coefficient of determination is introduced that nests and reinterprets the classical $R^2$ in least squares regression. In the third part, probabilistic top lists are proposed as a novel type of prediction in classification, which bridges the gap between single-class predictions and predictive distributions. The probabilistic top list functional is elicited by strictly consistent evaluation metrics, based on symmetric proper scoring rules, which admit comparison of various types of predictions.
Ageing and relaxation times in disordered insulators

description: We focus on the slow relaxations observed in the conductance of disordered insulators at low temperature (especially granular aluminum films). They manifest themselves as a temporal logarithmic decrease of the conductance after a quench from high temperatures and the concomitant appearance of a field effect anomaly centered on the gate voltage maintained. We are first interested in ageing effects, i.e. the age dependence of the dynamical properties of the system. We stress that the formation of a second field effect anomaly at a different gate voltage is not a "history free" logarithmic (lnt) process, but departs from lnt in a way which encodes the system's age. The apparent relaxation time distribution extracted from the observed relaxations is thus not "constant" but evolves with time. We discuss what defines the age of the system and what external perturbation out of equilibrium does or does not rejuvenate it. We further discuss the problem of relaxation times and comment on the commonly used "two dip" experimental protocol aimed at extracting "characteristic times" for the glassy systems (granular aluminum, doped indium oxide...). We show that it is inoperable for systems like granular Al and probably highly doped InOx where it provides a trivial value only determined by the experimental protocol. But in cases where different values are obtained like in lightly doped InOx or some ultra thin metal films, potentially interesting information can be obtained, possibly about the "short time" dynamics of the different systems. Present ideas about the effect of doping on the glassiness of disordered insulators may also have to be reconsidered.

New high precision orbital and physical parameters of the double-lined low-mass spectroscopic binary BY Draconis

description: We present the most precise to date orbital and physical parameters of the well known short period (P=5.975 d), eccentric (e=0.3) double-lined spectroscopic binary BY Draconis, a prototype of a class of late-type, active, spotted flare stars. We calculate the full spectroscopic/astrometric orbital solution by combining our precise radial velocities (RVs) and the archival astrometric measurements from the Palomar Testbed Interferometer (PTI). The RVs were derived based on the high resolution echelle spectra taken between 2004 and 2008 with the Keck I/HIRES, Shane/CAT/HamSpec and TNG/SARG telescopes/spectrographs using our novel iodine-cell technique for double-lined binary stars. The RVs and available PTI astrometric data spanning over 8 years allow us to reach 0.2-0.5% level of precision in M sin3(i) and the parallax but the geometry of the orbit (i=154 deg) hampers the absolute mass precision to 3.3%, which is still an order of magnitude better than for previous studies. We compare our results with a set of Yonsei-Yale theoretical stellar isochrones and conclude that BY Dra is probably a main sequence system more metal-rich than the Sun. Using the orbital inclination and the available rotational velocities of the components, we also conclude that the rotational axes of the components are likely misaligned with the orbital angular momentum. Given BY Dra's main sequence status, late spectral type and the relatively short orbital period, its high orbital eccentricity and probable spin-orbit misalignment are not in agreement with the tidal theory. This disagreement may possibly be explained by smaller rotational velocities of the components and the presence of a substellar mass companion to BY Dra AB.

description: Chronic wounds and the accompanying inflammation are ongoing challenges in clinical treatment. They are usually accompanied by low pH and high oxidative stress environments, limiting cell growth and proliferation. Ordinary medical gauze has limited therapeutic effects on chronic wounds, and there is active research to develop new wound dressings. The chitosan hydrogel could be widely used in biomedical science with great biocompatibility, but the low mechanical properties limit its development. This work uses polyacrylamide to prepare double-network (DN) hydrogels based on bioadhesive catechol-chitosan hydrogels. Cystamine and N, N′-Bis(acryloyl)cystamine, which can be cross-linking agents with disulfide bonds to prepare redox-responsive DN hydrogels and pH-responsive nanoparticles (NPs) prepared by acetalized cyclodextrin (ACD) are used to intelligently release drugs against chronic inflammation microenvironments. The addition of catechol groups and ACD-NPs loaded with the Resolvin E1 (RvE1), promotes cell adhesion and regulates the inflammatory response at the wound site. The preparation of the DN hydrogel in this study can be used to treat and regulate the inflammatory microenvironment of chronic wounds accurately. It provides new ideas for using inflammation resolving factor loaded in DN hydrogel of good biocompatibility with enhanced mechanical properties to intelligent regulate the wound inflammation and promote the wound repaired.

description: Interrelated coagulation and inflammation are impediments to endothelialization, a prerequisite for the longterm function of cardiovascular materials. Here, we proposed a self-regulating anticoagulant coating strategy combined with anti-inflammatory capacity, which consisted of thrombin-responsive nanogels with anticoagulant and anti-inflammatory components. As an anticoagulant, rivaroxaban was encapsulated in nanogels cross-linked by thrombin-cleavable peptide and released upon the trigger of environmental thrombin, blocking the further coagulation cascade. The superoxide dismutase mimetic Tempol imparted the antioxidant property. Polyphenol epigallocatechin gallate (EGCG), in addition to its anti-inflammatory function in synergy with Tempol, also acted as a weak cross-linker to stabilize the coating. The effectiveness and versatility of this coating were validated using two typical cardiovascular devices as models, biological valves and vascular stents. It was demonstrated that the coating worked as a precise strategy to resist coagulation and inflammation, escorted reendothelialization on the cardiovascular devices, and provided a new perspective for designing endothelium-like functional coatings.

description: The observational manifestation of a neutron star is strongly connected with the properties of its magnetic field. During the star's lifetime, the field strength and its changes dominate the thermo-rotational evolution and the source phenomenology across the electromagnetic spectrum. Signatures of magnetic field evolution are best traced among elusive groups of X-ray emitting isolated neutron stars (INSs), which are mostly quiet in the radio and γ-ray wavelengths. It is thus important to investigate and survey INSs in X-rays in the hope of discovering peculiar sources and the long-sought missing links that will help us to advance our understanding of neutron star evolution. The Extended Röntgen Survey with an Imaging Telescope Array (eROSITA), the primary instrument on the forthcoming Spectrum-RG mission, will scan the X-ray sky with unprecedented sensitivity and resolution. The survey has thus the unique potential to unveil the X-ray faint end of the neutron star population and probe sources that cannot be assessed by standard pulsar surveys.

description: We have studied the fractional quantum Hall states on the surface of a topological insulator thin film in an external magnetic field, where the Dirac fermion nature of the charge carriers have been experimentally established only recently. Our studies indicate that the fractional quantum Hall states should indeed be observable in the surface Landau levels of a topological insulator. The strength of the effect will however be different, compared to that in graphene, due to the finite thickness of the topological insulator film and due to the admixture of Landau levels of the two surfaces of the film. At a small film thickness, that mixture results in a strongly non-monotonic dependence of the excitation gap on the film thickness. At a large enough thickness of the film, the excitation gap in the lowest two Landau levels are comparable in strength.

description: Galaxy mergers are expected to influence galaxy properties, yet measurements of individual merger histories are lacking. Models predict that merger histories can be measured using stellar halos and that these halos can be quantified using observations of resolved stars along their minor axis. Such observations reveal that Milky Way-mass galaxies have a wide range of stellar halo properties and show a correlation between their stellar halo masses and metallicities. This correlation agrees with merger-driven models where stellar halos are formed by satellite galaxy disruption. In these models, the largest accreted satellite dominates the stellar halo properties. Consequently, the observed diversity in the stellar halos of MilkyWay-mass galaxies implies a large range in the masses of their largest merger partners. In particular, the Milky Way's low mass halo implies an unusually quiet merger history. We used these measurements to seek predicted correlations between the bulge and central black hole (BH) mass and the mass of the largest merger partner. We found no significant correlations: while some galaxies with large bulges and BHs have large stellar halos and thus experienced a major or minor merger, half have small stellar halos and never experienced a significant merger event. These results indicate that bulge and BH growth is not solely driven by merger-related processes.
The design of organoiron and organic polymers containing azo dyes and calixarenes
Creators: name: Shipman, Patrick Oliver
Publisher: name: University of British Columbia
Year: 2010

description: Organic azo dye polymers are prepared from the ring-opening metathesis polymerization of azo dye functionalized norbornenes. These polymers are examined for their trans-cis¬ isomeration, UV-visible properties, and their acid sensing capabilities. The organoiron polymers are prepared through polycondensation reactions between organoiron azo dye complexes and O-, S-, or N-containing dinucleophiles. These polymers are analyzed for their thermal and UV-visible properties. The synthesis and characterization of upper rim functionalized calix[4]arenes are described. Calix[4]arenes containing propanol groups on either the 5- or both the 5- and 11- positions were prepared. These calixarenes also contained either: phenolic, propoxy, or t-butyl-dimethyl-siloxy groups on the lower rim. These calixarenes were reacted with chloro-terminated organoiron carboxylic acid complexes to prepare metallocalix[4]arenes containing one, two, or four metal centres on their upper rims. The metallocalix[4]arenes were used to prepare calix[4]arene containing azo dyes, or ferrocenes. These metallocalix[4]arenes were also used to prepare organoiron based polycalixarenes. Organic polymers were also prepared from the organic upper rim propanol functionalized calix[4]arenes. The metallocalix[4]arenes were additionally studied for their electrochemical properties. The azo dye containing metallocalix[4]arenes were studied for their UV-visible properties and acid sensing capabilities. The polycalix[4]arenes were additionally studied through gel permeation chromatography, thermal gravimetric analysis and differential scanning calorimetry.

description: Redlining was a segregatory lending practice instituted by the United States federal government during the New Deal. Although redlining is now illegal, it laid a foundation for disparities that are still present today. A growing body of research has linked redlining to disparities in health, socioeconomics and the environment. This study builds on this body of research within the context of historical redlining in the Sunbelt. The selection of Sunbelt cities, including Los Angeles (CA), Fresno (CA), San Jose (CA) and Phoenix (AZ), also recognizes the relevance of water scarcities, as the areas selected for this study experience persistent drought. As such, this study investigates the poorly studied topic of surface water equity within drought-affected areas. Finally, this study seeks to determine the interplay between socioeconomic factors and the environment in redlined cities using statistical methods. The data selected to capture socioeconomics in the study cities were housing prices (as determined by Zillow Zestimates), composition of zoning codes, and racial demographics. The data selected to investigate the environment were the amount of green and blue space, determined by the Normalized Difference Vegetation Index (NDVI) and the mapping of residential surface water (i.e. pools and fountains), respectively. Overall, this study has provided statistical evidence that disparities still remain in socioeconomics and the amount of blue and green spaces within historically redlined Sunbelt cities, however, more work is needed to fully understand the interplay between these two topics, as well as to establish solutions for an equitable future.

description: In view of new experimental data the instability against adiabatic nonaxisymmetric perturbations of a Taylor-Couette flow with an axial density stratification is considered in dependence of the Reynolds number (Re) of rotation and the Brunt-Väisälä number (Rn) of the stratification. The flows at and beyond the Rayleigh limit become unstable between a lower and an upper Reynolds number (for fixed Rn). The rotation can thus be too slow or too fast for the stratorotational instability. The upper Reynolds number above which the instability decays, has its maximum value for the potential flow (driven by cylinders rotating according to the Rayleigh limit) and decreases strongly for flatter rotation profiles finally leaving only isolated islands of instability in the (Rn/Re) map. The maximal possible rotation ratio μmax only slightly exceeds the shear value of the quasi-uniform flow with Uφ≃const. Along and between the lines of neutral stability the wave numbers of the instability patterns for all rotation laws beyond the Rayleigh limit are mainly determined by the Froude number Fr which is defined by the ratio between Re and Rn. The cells are highly prolate for Fr > 1 so that measurements for too high Reynolds numbers become difficult for axially bounded containers. The instability patterns migrate azimuthally slightly faster than the outer cylinder rotates.

description: Dieser Beitrag stellt einen elektrodynamischen Wandler vor, der im Vergleich zu konventionellen E‑Maschinen wettbewerbsfähige Betriebseigenschaften aufweist, beliebig skalierbar und kostengünstig herzustellen ist. Der Wandler ist geeignet, in vielfältigen Anwendungen als effizienter und effektiver Generator oder Motor eingesetzt zu werden. Der hier vorgestellte prototypische Wandler ist eine zweiphasige Außenläufer-Zahnpolmaschine mit permanenterregtem Rotor und Ringspulen am Stator. Die Maschine ist an das Klauenpolprinzip angelehnt und besitzt Zahnpolpaare. Der Versatz der beiden Teilsysteme zueinander beträgt elektrisch 90°, und sie erzeugen jeweils ein zeitlich pulsierendes Drehmoment. Die Rotorzahnreihen jedes Systems weisen jeweils einen elektrischen Versatz von 180° zueinander auf. Ein weichmagnetischer Kompositwerkstoff wird verwendet, um den magnetischen Fluss in allen drei Raumrichtungen führen zu können. Der Prototyp generiert pro Spule bei einer Drehzahl von 1500 U/min eine Spannung von 30 V und erzeugt eine extrapolierte Wirkleistung von 350 W.
description: This article presents an electrodynamic converter with competitive operating characteristics compared to conventional electric machines, good scalability, and inexpensive manufacturing. The converter is suitable for being used in a variety of applications as an efficient and effective generator or motor. The introduced prototypical converter is a two-phase external tooth pole machine with a permanently excited rotor and toroidal coils on the stator. The machine is based on the claw pole principle and has tooth pole pairs. The two subsystems have an electrical offset of 90° to one another, and each of them generates a torque that pulsates over time. The rows of rotor teeth in each system have an electrical offset of 180° to one another. A soft magnetic composite material is used to guide the magnetic flux in all three directions. The prototype generates a voltage of 30 V per coil at a speed of 1500 rpm and produces an extrapolated power of 350 W.
