Elucidation of the mechanism(s) required by CD8{u207A} T lymphocytes for control of different viral infections

description: CD8{u207A} Cytotoxic T lymphocytes (CTLs) are efficient in controlling virus infection because they are equipped with multiple effector mechanisms capable of either inducing cell death or an antiviral state within infected cells. These effector molecules include perforin (Prf), granzymes (Gzms) and gamma-interferon (IFN-{u03B3}). Through the use of gene knockout animals in various viral models, it is now well established that a deficit in any of these effector functions can result in a loss of virus control. However, these effector molecules are not exclusive to CTLs and other effector cells also utilize them, therefore it remains unclear if these effector mechanisms are actually required by CTLs to control virus infections. I employed 2 models of adoptive transfer of OT-I transgenic CTLs, specific for the ovalbumin (OVA)-derived peptide SIINFEKL and deficient in one or more effector molecule(s), combined with infection with various recombinant viruses expressing this peptide to identify the effector molecule(s) necessary for primary or memory CTLs in mediating antiviral activity against two closely related orthopoxviruses: ectromelia virus (ECTV-OVA), vaccinia virus (VACV-OVA). The adoptive transfer model was also used to investigate whether similar antiviral effector molecule(s) are required by primary CTLs to control other viruses such as herpes simplex virus type 1 (HSV-1-OVA) and influenza A virus (IAV-OVA). Our results show that the effector molecules required for antiviral functions of primary and memory CTLs directed towards two very closely related viruses, ECTV and VACV, are distinct. Prf is required by primary CTLs to control ECTV but not VACV, while IFN-{u03B3} is critical for VACV control but not ECTV. Although Gzm-deficient mice show increased susceptibility to ECTV, neither GzmA nor GzmB are necessary for CTLs to curb either ECTV or VACV replication. There are subtle differences in the degree of dependence on effector functions between primary and memory CTLs in the control of ECTV, as the loss of Prf only partially reduced the ability of memory CTL to control ECTV infection. We have also defined the effector functions required by primary CTLs for the control of HSV-1 and IAV infections and showed CTLs utilize distinctive mechanisms for the control of these other viruses.

description: High-resolution Doppler-resolved spectroscopy has opened up a new window into the atmospheres of both transiting and non-transiting exoplanets. Here, we present VLT/UVES observations of a transit of WASP-121b, an 'ultra-hot' Jupiter previously found to exhibit a temperature inversion and detections of multiple species at optical wavelengths. We present initial results using the blue arm of UVES ($\approx$3700-5000A), recovering a clear signal of neutral Fe in the planet's atmosphere at >8$σ$, which could contribute to (or even fully explain) the temperature inversion in the stratosphere. However, using standard cross-correlation methods, it is difficult to extract physical parameters such as temperature and abundances. Recent pioneering efforts have sought to develop likelihood `mappings' that can be used to directly fit models to high-resolution datasets. We introduce a new framework that directly computes the likelihood of the model fit to the data, and can be used to explore the posterior distribution of parameterised model atmospheres via MCMC techniques. Our method also recovers the physical extent of the atmosphere, as well as account for time- and wavelength-dependent uncertainties. We measure a temperature of $3710^{+490}_{-510}$K, indicating a higher temperature in the upper atmosphere when compared to low-resolution observations. We also show that the Fe I signal is physically separated from the exospheric Fe II. However, the temperature measurements are highly degenerate with aerosol properties; detection of additional species, using more sophisticated atmospheric models, or combining these methods with low-resolution spectra should help break these degeneracies.

description: A model describing the relationship between the ortho--positronium lifetime and the volume of a void, located in a synthetic zeolite, is analyzed. Our idea, which allows us to take into account the effects of temperature, comprises the introduction of a non--hermitian term in the Hamiltonian, which accounts for the annihilation of the ortho--positronium. The predictions of the present model are also confronted against an already known experimental result.

Relativistic finite temperature multifluid hydrodynamics in a neutron star from a variational principle

Year: 2020
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We develop a relativistic multifluid dynamics appropriate for describing neutron star cores at finite temperatures based on Carter's convective variational procedure. The model includes seven fluids, accounting for both normal and superfluid/superconducting neutrons and protons, leptons (electrons and muons) and entropy. The formulation is compared to the non-variational relativistic multifluid hydrodynamics of Gusakov and collaborators and shown to be equivalent. Vortex lines and flux tubes, mutual friction, vortex pinning, heat conduction and viscosity are incorporated into the model in steps after the basic hydrodynamics is described. The multifluid system is then considered at the mesoscopic scale where the currents around individual vortex lines and flux tubes are important, and this mesoscopic theory is averaged to determine the detailed vortex line/flux tube contributions to the macroscopic "effective" theory. This matching procedure is partially successful, though obtaining full agreement between the averaged mesoscopic and macroscopic effective theory requires discarding subdominant terms. The matching procedure allow us to interpret the magnetic $H$-field inside a neutron star in a way that is consistent with condensed matter physics literature, and to clarify the difference between this interpretation and that in previous astrophysical works.

UK strategies for digital preservation and digital curation
Creators: name: Rusbridge, Chris
Publisher: name: Zenodo
Year: 2005

description: The UK has long been active in digital preservation. Following a series of international workshops, the Digital Preservation Coalition was set up in 2001. Meanwhile, other parts of the UK were becoming heavily engaged in e-science, and bearing these developments in mind, the Digital Curation Centre was formed in 2004. These two organisations are founded and funded on very different principles and scales, and are looking at related problems from different angles; nevertheless, they aim to complement and mutually support each other. This session will provide some context and background on the two organisations and their approach, leading towards a discussion of relevant issues from an IASSIST perspective.

description: We report the first spectroscopic observations of a background star seen through the region between the ionization front and the dissociation front of the nebula IC 63. This photodissociation region (PDR) exhibits intense extended red emission (ERE) attributed to fluorescence by large molecules/ions. We detected strong diffuse interstellar bands (DIB) in the stellar spectrum, including an exceptionally strong and broad DIB at $λ$4428. The detection of strong DIBs in association with ERE could be consistent with the suggestion that the carriers of DIBs and ERE are identical. The likely ERE process is recurrent fluorescence, enabled by inverse internal conversions from highly excited vibrational levels of the ground state to low-lying electronic states with subsequent transitions to ground. This provides a path to rapid radiative cooling for molecules/molecular ions, greatly enhancing their ability to survive in a strongly irradiated environment. The ratio of the equivalent widths (EW) of DIBs $λ$5797 and $λ$5780 in IC 63 is the same as that observed in the low-density interstellar medium with UV interstellar radiation fields (ISRF) weaker by at least two orders of magnitude. This falsifies suggestions that the ratio of these two DIBs can serve as a measure of the UV strength of the ISRF. Observations of the nebular spectrum of the PDR of IC 63 at locations immediately adjacent to where DIBs were detected failed to reveal any presence of sharp emission features seen in the spectrum of the Red Rectangle nebula. This casts doubts upon proposals that the carriers of these features are the same as those of DIBs seen at slightly shorter wavelengths.

Mindfulness-based cognitive therapy for recurrent depression and anxiety

description: Mindfulness-based Cognitive Therapy (MBCT) is a class-based manualised program designed to treat recurrent depression and prevent relapse. MBCT has been found to be effective for both symptomatic and asymptomatic patients with three or more previous episodes of depression. While research estimates that 50 - 75% of individuals with depression also experience anxiety, the role of anxiety in the MBCT treatment of recurrent depression is not clearly understood. The aim of the present study was to fill this gap in the literature in order to understand the effect that MBCT has on anxiety outcomes, and the effect that anxiety has on depression outcomes. Sixty-seven individuals with recurrent depression completed an MBCT course and were followed for up to 49 months. MBCT was found to significantly reduce levels of anxiety, both in the short and long-term. Secondly, while MBCT was effective in reducing levels of depression and depressive relapse, it was more effective for individuals who were not clinically anxious at the beginning of treatment. The results support the use of MBCT in treating individuals with recurrent depression and co-occurring anxiety, in order to reduce depressive and anxiety symptoms. Future research into ways that the MBCT protocol could be adapted to better accommodate individuals with anxiety may reduce the discrepancy between those with and without anxiety symptoms, and greatly assist the large proportion of individuals who enroll in MBCT programs and who experience both recurrent depression and anxiety.

description: The bulk partition function of pure Chern-Simons theory on a three-manifold is a state in the space of conformal blocks of the dual boundary RCFT, and therefore transforms non-trivially under the boundary modular group. In contrast the bulk partition function of AdS(3) string theory is the modular-invariant partition function of the dual CFT on the boundary. This is a puzzle because AdS(3) string theory formally reduces to pure Chern-Simons theory at long distances. We study this puzzle in the context of massive Chern-Simons theory. We show that the puzzle is resolved in this context by the appearance of a chiral "spectator boson" in the boundary CFT which restores modular invariance. It couples to the conformal metric but not to the gauge field on the boundary. Consequently, we find a generalization of the standard Chern-Simons/RCFT correspondence involving "nonholomorphic conformal blocks" and nonrational boundary CFTs. These generalizations appear in the long-distance limit of AdS(3) string theory, where the role of the spectator boson is played by other degrees of freedom in the theory.

Because $n>g$ this divisor $D$ has unique representative $ρ(D)$ in the Jacobian which can be constructed by using dim$|D|=n-g$ steps of Abel's algorithm. We study properties of the corresponding chain of divisors and prove that the classical $GL(3)$ magnetic chain is a superintegrable system with dim$|D|=2$ superintegrable Hamiltonians.

description: The increasing importance of cross-national research has resulted in an astonishing growth in the usage of international data over recent years. ESDS International provides academics across the UK with access to the major international databanks produced by international governmental agencies such as the United Nations, International Monetary Fund and World Bank. In this paper we describe how an emerging new user community for these databanks has been developed and supported, and the challenges of responding to a diverse and expanding user group. We report some of the problems users face accessing and using the data in their teaching and research and how these barriers can be overcome. Finally, we examine how the rapid growth in usage in the UK is reflected in current global trends and the potential demand for access to these databanks worldwide.

description: Both managed and native languages use memory safety techniques to ensure program correctness and as a security defense. A critical element of memory safety is to initialize newly allocated memory to zero before making it available to the program. In this thesis I explore the performance impact of zero initialization and show that it comes with a substantial overhead. I also show that this overhead can be largely removed with new designs that exploit both the language semantics of zero initialization and the hardware semantics of memory hierarchies. Programmers increasingly choose managed languages to develop large scale applications. One of the reasons is that managed languages offer automatic memory management (garbage collection), which protects against memory leaks and dangling pointers. Garbage collection encourages programs to allocate large numbers of small and medium size objects, leading to significant overheads of zero initializing objects - on average the direct cost of zeroing is 4% to 6% and up to 50% of total application time on a variety of modern processors. Zeroing incurs indirect costs as well, which include memory bandwidth consumption and cache displacement. Existing virtual machines (VMs) either: a) minimize direct costs by zeroing in large blocks, or b) minimize indirect costs by integrating zeroing into the allocation sequence to reduce cache displacement. This thesis first describes and evaluates zero initialization costs and the two existing designs. The microarchitectural analysis of prior designs inspires two better designs that exploit concurrency and non-temporal cache-bypassing store instructions to reduce the direct and indirect costs simultaneously. The best strategy is to adaptively choose between the two new designs based on CPU utilization. This approach improves over widely used hot-path zeroing by 3% on average and up to 15% on the newest Intel i7-2600 processor, without slowing down any of the benchmarks. These results indicate that zero initialization is a surprisingly important source of overhead in existing VMs and that our new software strategies are effective at reducing this overhead. These findings also invite other optimizations, including software elision of zeroing and microarchitectural support.
The production and presentation of statistics of unemployment: comparability issues
Creators: name: Adams, John

Publisher: name: Zenodo
Year: 2005

description: The United Nations publish unemployment statistics for 123 countries. Most of these statistics are based on International Labour Office (ILO) criteria for the definition of unemployment, but many countries also produce unemployment statistics based on insurance records and on the basis of registered unemployment. The paper aims to compare the main features of different series. The dimensions compared include the conceptual basis for the definition of unemployment, use of denominators for production of unemployment rates, boundaries with employment and inactivity, entry statistics and duration of unemployment, and the cultural influence of the statistics. The paper identifies conflicts between achieving international comparability and national needs. Survey statistics that underpin international comparisons do not support geographically detailed analysis within countries. The value of ILO statistics also is limited by failure to recognise the concept of entry to unemployment and difficulties of integration with other unemployment statistics. The standard LFS questionnaire could be modified to support the production of statistics for entrants to unemployment. The sampling frame could be modified to ensure consistency with nationally produced insurance or registered unemployment statistics. (The research for this paper has been supported by a grant to John Adams from Scotecon and by the award of a Campion Fellowship by the Royal Statistical Society to Ray Thomas)

description: In this paper we derive the Clauser-Horne (CH) inequality for the full electron counting statistics in a mesoscopic multiterminal conductor and we discuss its properties. We first consider the idealized situation in which a flux of entangled electrons is generated by an entangler. Given a certain average number of incoming entangled electrons, the CH inequality can be evaluated for different numbers of transmitted particles. Strong violations occur when the number of transmitted charges on the two terminals is the same ($Q_1=Q_2$), whereas no violation is found for $Q_1\ne Q_2$. We then consider two actual setups that can be realized experimentally. The first one consists of a three terminal normal beam splitter and the second one of a hybrid superconducting structure. Interestingly, we find that the CH inequality is violated for the three terminal normal device. The maximum violation scales as 1/M and $1/M^2$ for the entangler and normal beam splitter, respectively, 2$M$ being the average number of injected electrons. As expected, we find full violation of the CH inequality in the case of the superconducting system.

description: The sensitivity of a large range of turbulence closures to the near-wall grid resolution is assessed through analytical and numerical techniques. We determine model boundedness, limiting behaviour, and solution dependence of channel flow simulations to the near-wall cell size y1+. The sensitivity of present simulations to y1+ is strongly dependent on the choice of scale determining variable; ε and ω based models can lead to friction velocity errors of 1.5% and 4.74% at y1+≈1, the latter due to the singular behaviour of ω close to the wall. Here this is mitigated by adopting mathematically equivalent k−ω′, k−g or k−τ models, which reduce errors by an order of magnitude to <0.1% at y1+≈0.3. The k−τ model is insensitive to y1+ motivating a new closure with updated coefficients and a cross diffusion term, with the aim to ensure its applicability to a wider range of flows.

description: A flat band in fermionic system is a dispersionless single-particle state with a diverging effective mass and nearly zero group velocity. These flat bands are expected to support exotic properties in the ground state, which might be important for a wide range of promising physical phenomena. For many applications it is highly desirable to have such states in Dirac materials, but so far they have been reported only in non-magnetic Dirac systems. In this work we propose a realization of topologically protected spin-polarized flat bands generated by domain walls in planar magnetic topological insulators. Using first-principles material design we suggest a family of intrinsic antiferromagnetic topological insulators with an in-plane sublattice magnetization and a high Néel temperature. Such systems can host domain walls in a natural manner. For these materials, we demonstrate the existence of spin-polarized flat bands in the vicinity of the Fermi level and discuss their properties and potential applications.

The data librarian was also the map librarian so geospatial /GIS data became her responsibility as well. Data (including geospatial data) services to faculty and students have developed: FROM the past (1997-2003) when they were Library centred; low profile, minimum resources for staff, equipment or computers; TO the present (2003-2006) where they are university centred with a Geospatial, Map and Data Centre, full time technician, server space and Web delivery of some data; TO the future (200?) - provincially centred, with the possibility of centrally archived and networked delivery of social science and geospatial data to Ontario universities. Techniques used at Ryerson to give data services sufficient profile to attract funding and future scenarios being considered by the Ontario universities Data and Map librarians' groups for province wide delivery will be examined.

description: We introduce Gaussian-enhanced Surfels (GESs), a bi-scale representation for radiance field rendering, wherein a set of 2D opaque surfels with view-dependent colors represent the coarse-scale geometry and appearance of scenes, and a few 3D Gaussians surrounding the surfels supplement fine-scale appearance details. The rendering with GESs consists of two passes -- surfels are first rasterized through a standard graphics pipeline to produce depth and color maps, and then Gaussians are splatted with depth testing and color accumulation on each pixel order independently. The optimization of GESs from multi-view images is performed through an elaborate coarse-to-fine procedure, faithfully capturing rich scene appearance. The entirely sorting-free rendering of GESs not only achieves very fast rates, but also produces view-consistent images, successfully avoiding popping artifacts under view changes. The basic GES representation can be easily extended to achieve anti-aliasing in rendering (Mip-GES), boosted rendering speeds (Speedy-GES) and compact storage (Compact-GES), and reconstruct better scene geometries by replacing 3D Gaussians with 2D Gaussians (2D-GES). Experimental results show that GESs advance the state-of-the-arts as a compelling representation for ultra-fast high-fidelity radiance field rendering.

description: The role of stoichiometry and growth temperature in the preferential nucleation of material phases in the Li-Nb-O family are explored yielding an empirical growth phase diagram. It is shown that while single parameter variation often produces multi-phase films, combining substrate temperature control with the previously published lithium flux limited growth allows the repeatable growth of high quality single crystalline films of many different oxide phases. Higher temperatures (800-1050 °C) than normally used in MBE were necessary to achieve high quality materials. At these temperatures the desorption of surface species is shown to play an important role in film composition. Using this method single phase films of NbO, NbO$_{2}$, LiNbO$_{2}$, Li$_{3}$NbO$_{4}$, LiNbO$_{3}$, and LiNb$_{3}$O$_{8}$ have been achieved in the same growth system, all on c-plane sapphire. Finally, the future of these films in functional oxide heterostructures is briefly discussed.

description: We consider spherically symmetric black holes with minimally coupled scalar fields and concentrate our attention on asymptotically flat self-gravitating configurations having the event horizons located at radii much smaller than $2m$. We think of such configurations as rigorous mathematical models of the gravitating objects, surrounded by dark matter, in the centres of normal galaxies. It turns out that the radius of the event horizon of a scalar field black hole always less than the Schwarzschild radius of vacuum black hole of the same mass and can be arbitrary close to zero. In astronomical observations, a key role in distinguishing between black holes, wormholes, and naked singularities plays measuring parameters of bound quasiperiodic orbits, in particular, the shape of an orbit and the angle of precession of its pericentre. We consider a typical two-parameter family of compact scalar field black holes and compute numerically the shapes of some bound orbits. We find that a key feature of bound orbits around a compact black hole is that the angle between closest pericentre points is either negative or, at least, less than that for the Schwarzschild black hole of the same mass.

Detection of D2H+ in the Dense Interstellar Medium

description: The 692 GHz para ground-state line of D2H+ has been detected at the Caltech Submillimeter Observatory towards the pre-stellar core 16293E. The derived D2H+ abundance is comparable to that of H2D+, as determined by observations of the 372 GHz line of ortho-H2D+. This is an observational verification of recent theoretical predictions (Roberts, Herbst & Millar 2003), developed to explain the large deuteration ratios observed in cold, high-density regions of the interstellar medium associated with low mass pre-stellar cores and protostars. This detection confirms expectations that the multiply deuterated forms of H3+ were missing factors of earlier models. The inclusion of D2H+ and D3+ in the models leads to predictions of higher values of the D/H ratio in the gas phase.

Networking in the University Environment: Building Bridges From the Bottom Up

description: Bridges are rarely built in a day and often their foundations are hidden below the waterline where few are able to see. Building networks for data collections and services in a university community takes time and requires individuals who are willing to take it upon themselves to draft the schematics and collect the raw materials before bridges can be built between major organizations within the community. This paper focuses on the collaborative efforts of the University Libraries and the Population Research Institute at The Pennsylvania State University. We will discuss past and current initiatives that have been successful in laying the foundation for future initiatives including: resource authentication, collection building, and promotional activities. We will conclude with a discussion of ideas for future collaboration focusing on distributive reference services, team teaching and other potential partners. It is imperative that we present coherent and cohesive projects that are comprehensible to our organizations' administrators; therefore a considerable amount of thought and experimentation through informal collaboration is necessary beforehand. By developing a history of collaboration through doable and successful projects, visible bridges can be built between seemingly independent organizations within the university community.

description: Encoding information onto optical fields is the backbone of modern telecommunication networks. Optical fibers offer low loss transport and vast bandwidth compared to electrical cables, and are currently also replacing coaxial cables for short-range communications. Optical fibers also exhibit significantly lower thermal conductivity, making optical interconnects attractive for interfacing with superconducting circuits and devices. Yet little is known about modulation at cryogenic temperatures. Here we demonstrate a proof-of-principle experiment, showing that currently employed Ti-doped LiNbO modulators maintain the Pockels coefficient at 3K---a base temperature for classical microwave amplifier circuitry. We realize electro-optical read-out of a superconducting electromechanical circuit to perform both coherent spectroscopy, measuring optomechanically-induced transparency, and incoherent thermometry, encoding the thermomechanical sidebands in an optical signal. Although the achieved noise figures are high, approaches that match the lower-bandwidth microwave signals, use integrated devices or materials with higher EO coefficient, should achieve added noise similar to current HEMT amplifiers, providing a route to parallel readout for emerging quantum or classical computing platforms.

description: Technology has changed the way that people seek information. We can access an unimaginable amount of information with our fingertips. Much social science data can be easily obtained on the Web. What are the processes and mechanisms behind those tabular social science data on the Web? What are the caveats associated with those well-packaged data? When users depend on search engines to find information, a data librarian needs to guide them to locate pertinent data in the information haystacks. Many data producers are using Web technology to disseminate their data. How are these changes affecting social science data libraries and their staffs? This paper examines the service shift in a social science data library over the last five years and presents its plan for the future.

description: We consider versions of the grasshopper problem (Goulko and Kent, 2017) on the circle and the sphere, which are relevant to Bell inequalities. For a circle of circumference $2π$, we show that for unconstrained lawns of any length and arbitrary jump lengths, the supremum of the probability for the grasshopper's jump to stay on the lawn is one. For antipodal lawns, which by definition contain precisely one of each pair of opposite points and have length $π$, we show this is true except when the jump length $ϕ$ is of the form $π\frac{p}{q}$ with $p,q$ coprime and $p$ odd. For these jump lengths we show the optimal probability is $1 - 1/q$ and construct optimal lawns. For a pair of antipodal lawns, we show that the optimal probability of jumping from one onto the other is $1 - 1/q$ for $p,q$ coprime, $p$ odd and $q$ even, and one in all other cases. For an antipodal lawn on the sphere, it is known (Kent and Pitalúa-García, 2014) that if $ϕ= π/q$, where $q \in \mathbb N$, then the optimal retention probability of $1-1/q$ for the grasshopper's jump is provided by a hemispherical lawn. We show that in all other cases where $0
