The role of macrophages in the age-dependent susceptibility to coxsackievirus B3 infection
Creators: name: Girn, Jaskamal
Publisher: name: University of British Columbia
Year: 2009

description: Group B coxsackieviruses (CVB) are etiological agents of a febrile exanthematous disease that may be complicated by viral myocarditis, pancreatitis, and encephalitis. CVB infections are notable for being extremely severe in the very young compared to adult hosts. Preliminary work in mice has shown that macrophages contribute to host resistance to CVB3, since depletion of macrophages in vivo resulted in a more exacerbated infection. Based on this finding, the overall objective of this study was to dissect the specific properties of macrophages which participated in resistance against CVB3 and to compare them between young and adult CD-I mice. It was found that macrophages from young CD-I mice were less efficient in inactivating CVB3 in vitro than adult mice. Comparison of NO production by macrophages from young and adult CD-I mice in vitro demonstrated that young mice were not impaired in their ability to produce this antiviral molecule; in fact, the younger animals produced significantly greater levels of NO following induction by IFN-γ, or LFN- γ plus TNF-α. In conjunction with this, the importance of NO in CVB3 resistance in vivo was determined by treatment of young and adult CD-I mice with a NOS enzyme inhibitor, L-NMMA. The resulting diminished activity of NOS caused a more severe infection in both the young and adult CD-I mice, with the effects generally more pronounced in the younger animals. Comparison of TNF-α production by macrophages from young and adult CD-I mice in vitro showed that the younger animals produced less of the cytokine following induction by IFN- γ plus LPS. Strain variation was also found in macrophage functions between CD-I mice and BALB/c mice (the latter being extremely susceptible to CVB3 resulting in mortality). It was found that virus inactivation by macrophages from young and adult BALB/c mice was markedly different, with macrophages from the younger mice being permissive to viral replication. In addition, TNF-α was produced in greater quantities by macrophages from the young mice, contrary to the results obtained with the CD-I mice. NO production by macrophages from BALB/c mice, however, followed a similar trend to the CD-I mice, with the younger animals producing more NO than the older animals. The mechanism for the extreme susceptibility (and mortality) in the BALB/c may involve the relatively high levels of TNF-α and NO generated by the younger mice, which may produce detrimental effects, like shock.
The fundamental plane of isolated early-type galaxies

description: Here we present new measurements of effective radii, surface brightnesses and internal velocity dispersions for 23 isolated early-type galaxies. The photometric properties are derived from new multi-colour imaging of 10 galaxies, whereas the central kinematics for 7 galaxies are taken from forthcoming work by Hau & Forbes. These are supplemented with data from the literature. We reproduce the colour-magnitude and Kormendy relations and strengthen the result of Paper I that isolated galaxies follow the same photometric relations as galaxies in high density environments. We also find that some isolated galaxies reveal fine structure indicative of a recent merger while others appear undisturbed. We examine the Fundamental Plane in both traditional R_e, mu_e and sigma space and also kappa-space. Most isolated galaxies follow the same Fundamental Plane tilt and scatter for galaxies in high density environments. However, a few galaxies notably deviate from the plane in the sense of having smaller M/L ratios. This can be understood in terms of their younger stellar populations, which are presumably induced by a gaseous merger. Overall, isolated galaxies have similar properties to those in roups and clusters with a slight enhancement in the frequency of recent mergers/interactions.

Quasi-Classical Rules for Qubit Spin-Rotation Error Suppression
Creators: name: Su, Qile David
Publisher: name: arXiv
Year: 2020
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A frequently encountered source of systematic error in quantum computations is imperfections in the control pulses which are the classical fields that control qubit gate operations. From an analysis of the quantum mechanical time-evolution operator of the spin wavefunction, it has been demonstrated that composite pulses can mitigate certain systematic errors and an appealing geometric interpretation was developed for the design of error-suppressing composite pulses. Here we show that these same pulse sequences can be obtained within a quasi-classical framework. This raises the question of whether error-correction procedures exist that exploit entanglement in a manner that can not be reproduced in the quasi-classical formulation.

description: This article is concerned with certain aspects of the entrepreneurial behaviour of wheat farmers - in particular, with their adoption of new techniques and means of production. The study is based on data secured in the course of a field investigation carried out late in 1953, in which forty-eight wheat farmers, residing in a particular locality in northern New South Wales, were interviewed. The primary aim of the investigation was not to estimate the extent to which particular technological innovations are being adopted throughout the wheat belt, or in any particular part of it. Its aim was, rather, to gain some idea of the factors which influence farmers in either adopting or not adopting a particular innovation, or innovations in general. In other words, it sought to explain differences in farmers' entrepreneurial behaviour, rather than estimate the relative preponderance of different types of behaviour.
A Detailed Observation of a LMC Supernova Remnant DEM L241 with XMM-Newton

description: We report on an {\it XMM-Newton} observation of the supernova remnant (SNR) \object{DEM L241} in the Large Magellanic Cloud. In the soft band image, the emission shows an elongated structure, like a killifish, with a central compact source. The compact source is point-like, and named as XMMU J053559.3$-$673509. The source spectrum is well reproduced with a power-law model with a photon index of $Γ= 1.57$ (1.51--1.62) and the intrinsic luminosity is $2.2\times 10^{35} \mathrm{ergs s^{-1}}$ in the 0.5--10.0 keV band, with the assumed distance of 50 kpc. The source has neither significant coherent pulsations in $2.0\times 10^{-3}$ Hz--8.0 Hz, nor time variabilities. Its luminosity and spectrum suggest that the source might be a pulsar wind nebula (PWN) in DEM L241. The spectral feature classifies this source into rather bright and hard PWN, which is similar to those in Kes 75 and B0540$-$693. The elongated diffuse structure can be divided into a ``Head'' and ``Tail'', and both have soft and line-rich spectra. Their spectra are well reproduced by a plane-parallel shock plasma ({\it vpshock}) model with a temperature of 0.3--0.4 keV and over-abundance in O and Ne and a relative under-abundance in Fe. Such an abundance pattern and the morphology imply that the emission is from the ejecta of the SNR, and that the progenitor of DEM L241 is a very massive star, more than 20 M\sun. This result is also supported by the existence of the central point source and an OB star association, LH 88. The total thermal energy and plasma mass are $\sim 4\times 10^{50}$ ergs and $\sim 200$ M\sun, respectively.

Jackiw-Teitelboim Gravity in the Second Order Formalism

description: We formulate the path integral for Jackiw-Teitelboim gravity in the second order formalism working directly with the metric and the dilaton. We consider the theory both in Anti-de Sitter(AdS) and de Sitter space(dS) and analyze the path integral for the disk topology and the "double trumpet" topology with two boundaries. We also consider its behavior in the presence of conformal matter. In the dS case the path integral evaluates the wavefunction of the universe which arises in the no-boundary proposal. In the asymptotic AdS or dS limit without matter we get agreement with the first order formalism. More generally, away from this limit, the path integral is more complicated due to the presence of modes from the gravity-dilaton sector and also matter sector with short wavelengths along the boundary that are smaller than the AdS or dS scales. In the double trumpet case, for both AdS and dS, we find that bosonic matter gives rise to a diverging contribution in the moduli space integral rendering the path integral ill-defined. The divergence occurs when the size of the wormhole neck vanishes and is related to the Casimir effect. For fermions this divergence can be avoided by imposing suitable boundary conditions. In this case, in dS space the resulting path integral gives a finite contribution for two disconnected universes to be produced by quantum tunneling.

description: Motivated by the TeV-scale gravity scenarios, we study gravitational radiation in the head-on collision of two black holes in higher dimensional spacetimes using a close-limit approximation. We prepare time-symmetric initial data sets for two black holes (the so-called Brill-Lindquist initial data) and numerically evolve the spacetime in terms of a gauge invariant formulation for the perturbation around the higher-dimensional Schwarzschild black holes. The waveform and radiated energy of gravitational waves emitted in the head-on collision are clarified. Also, the complex frequencies of fundamental quasinormal modes of higher-dimensional Schwarzschild black holes, which have not been accurately derived so far, are determined.

description: We investigate a mechanism for the robust identification of the center of a developing biological system. We assume the existence of two morphogen gradients, an activator emanating from the anterior, and a co-repressor from the posterior. The co-repressor inhibits the action of the activator in switching on target genes. We apply this system to Drosophila embryos, where we predict the existence of a hitherto undetected posterior co-repressor. Using mathematical modelling, we show that a symmetric activator-co-repressor model can quantitatively explain the precise mid-embryo expression boundary of the hunchback gene, and the scaling of this pattern with embryo size.

description: We propose to measure the coherent elastic neutrino nucleus scattering (CE$ν$NS) using a dual-phase liquid argon time projection chamber (TPC) with 200kg fiducial mass. The detector is expected to be adjacent to the JUNO-TAO experiment and to be about 35m from a reactor core with 4.6GW thermal power at Taishan. The antineutrino flux is approximately 6$\times10^{12}$cm$^{-1}$s$^{-1}$ at this location, leading to more than 11,000 coherent scattering events per day in the fiducial mass. However, the nuclear recoil energies concentrate in the sub-keV region, corresponding to less than ten ionisation electrons in the liquid argon. The detection of several ionisation electrons can be achieved in the dual-phase TPC due to the large amplification in the gas region. With a feasible detection threshold of four ionisation electrons, the signal rate is 955 per day. The detector is designed to be shielded well from cosmogenic backgrounds and ambient radioactivities to reach a 16% background-to-signal ratio in the energy region of interest. With the large CE$ν$NS sample, the expected sensitivity of measuring the weak mixing angle $\sin^{2}θ_{W}$, and of limiting the neutrino magnetic moment are discussed. In addition, a synergy between the reactor antineutrino CE$ν$NS experiment and the dark matter experiment is foreseen.

description: The scientific study of farm management and of the pattern of rural activities is destined to play an increasingly important role in the future development of Australian agriculture. Scope for expansion in primary production lies in two directions. First, in the improvement of farming techniques within the present boundaries of major agricultural development. This applies particularly to the main crop and livestock areas which experience comparatively high rainfalls. Second, in the development of new areas beyond the present margins of agriculture, by means of new techniques designed to improve natural conditions, such as irrigation works, the application of deficient minerals to soils, and other measures. It is evident that development along each of these lines can be most rational only if adequate account is taken of the many complex factors which influence farm management. Farm management and farm survey research seek to do this. The information gained by such research serves two main purposes, in that it assists both extension work and policy formation. From the viewpoint of extension, the most important use of farm management and farm survey research is to provide detailed information on which to base accurate advice on the economic aspects of various farm practices and methods of farm organization. Secondly, if agricultural policy, in respect of price levels, credit facilities, tenure, etc., is to be realistic, it must be based on adequate information as to farmers' problems and attitudes and the many factors affecting farm management and the level of output.

description: Crop rotations and soil-management practices on a random sample of mixed crop and livestock properties on the North- Western Slope were discussed in the last issue of this journal. The survey on which the latter article was based was carried out in March, April and May, 1952, and seventy-six farmers were visited in the shires of Peel, Liverpool Plains, Macintyre and Yallaroi. As the survey was concerned mainly with practices on wheat farms, the sample was drawn from important wheat-growing districts in different parts of the North Western Slope. The first article included an analysis of the influence of the size of farms and different soil types on the cropping practices adopted throughout the area. In order to compare the practices of holdings of different size groups, farms of 600 acres, or less, arable, and of a total area not exceeding 1,000 acres, were classed as "small" farms and the remainder as "large" farms. A significant relation was found to exist between the crop rotations followed on farms in these two size-groups, ninety per cent. of the small holdings having a rotation of one-year in-two, or shorter, compared with fifty-five per cent. for the large properties. It was also found that higher incomes in recent years, largely due to higher wool prices, have enabled farmers, especially those on small holdings, to introduce wider crop rotations and other soil conserving practices.

description: The absorption of traveling photons resonant with electric dipole transitions of an atomic gas naturally leads to electric dipole spin wave excitations. For a number of applications, it would be highly desirable to shape and coherently control the spatial waveform of the spin waves before spontaneous emission can occur. This paper details a recently developed optical control technique to achieve this goal, where counter-propagating, shaped sub-nanosecond pulses impart sub-wavelength geometric phases to the spin waves by cyclically driving an auxiliary transition. In particular, we apply this technique to reversibly shift the wave vector of a spin wave on the $D2$ line of laser-cooled $^{87}$Rb atoms, by driving an auxiliary $D1$ transition with shape-optimized pulses, so as to shut off and recall superradiance on demand. We investigate a spin-dependent momentum transfer during the spin-wave control process, which leads to a transient optical force as large as $\sim 1\hbar k$/ns, and study the limitations to the achieved $70\sim 75\%$ spin wave control efficiency by jointly characterizing the spin-wave control and matterwave acceleration. Aided by numerical modeling, we project potential future improvements of the control fidelity to the $99\%$ level when the atomic states are better prepared and by equipping a faster and more powerful pulse shaper. Our technique also enables a background-free measurement of the superradiant emission to unveil the precise scaling of the emission intensity and decay rate with optical depth.

description: As the number of installed meters in buildings increases, there is a growing number of data time-series that could be used to develop data-driven models to support and optimize building operation. However, building data sets are often characterized by errors and missing values, which are considered, by the recent research, among the main limiting factors on the performance of the proposed models. Motivated by the need to address the problem of missing data in building operation, this work presents a data-driven approach to fill these gaps. In this study, three different autoencoder neural networks are trained to reconstruct missing short-term indoor environment data time-series in a data set collected in an office building in Aachen, Germany. This consisted of a four year-long monitoring campaign in and between the years 2014 and 2017, of 84 different rooms. The models are applicable for different time-series obtained from room automation, such as indoor air temperature, relative humidity and $CO_{2}$ data streams. The results prove that the proposed methods outperform classic numerical approaches and they result in reconstructing the corresponding variables with average RMSEs of 0.42 °C, 1.30 % and 78.41 ppm, respectively.

description: This article represents the early stages of a broad enquiry into the marketing of meat. As such the results are tentative only and often uncompleted. To date the work has been concerned mainly with fat lamb prices and supply although a number of side excursions have been made. It has been calculated that total expenditure on meat at the retail level has kept pace with the growth of money income; in other words, when money income increased by, say, one per cent, consumers spent one per cent more on meat (lamb, mutton, beef and pork). While the total quantity consumed per year per caput has not risen substantially considerable shifts have occurred in the consumption of different types of meat and, in particular, the consumption of lamb has increased at the expense of beef consumption. The changes in consumption of these two commodities are closely associated with changes in the price ratio of these two commodities and income.
Utopia della montagna sacra

description: L’immagine della montagna si è costruita intorno all’idea di un’entità connotata da una notevole massa a cui è stata spesso associata la percezione di essere una zona impervia. Questo luogo, caratterizzato da notevole altezza ed estensione e difficile percorrenza, ha segnato profondamente l’immaginazione umana tant’è che, nel corso dei secoli e in più culture, alla montagna sono stati attribuiti valori simbolici rappresentativi sia di un’idea di potenza che di trascendenza. Secondo il mito greco, la cima della montagna fu il luogo divino dell’unione fra la Terra (Hera) e il Cielo (Zeus) mentre in più religioni e culture l’idea di ascensione al cielo tramite la montagna fu avvertito come un percorso di purificazione, luogo di ritorno al “principio” e manifestazione del sacro. Ciò premesso, scopo del presente articolo è indagare alcuni scenari immaginifici che hanno connotato culture diverse sia temporalmente che spazialmente. Partendo dalla concezione gnoseologica dell’antico Imago Mundi, il primo scenario si propone di analizzare le relazioni se non equivalenze idiomatiche e concettuali tra immaginazione, utopia e montagna, fino a sfociare nei supposti gnoseologici dello Speculum Mundi dell’arte rinascimentale attraverso la rappresentazione della montagna in pittura. Nel rinascimento (Pinturicchio, Mantegna, Leonardo, ecc.), la montagna diventa parte di un paesaggio inscrivibile nella concezione di estasi, il fuori-di-sé in quanto connessione tra macro e microcosmo, sensibile e intellegibile. Il secondo scenario sviluppa il tema simbolico della montagna in ambito contemporaneo attraverso l’opera dell’artista cinese Yang Yongliang che, partendo dalla tradizione pittorica cinese di rappresentazione dei paesaggi montuosi quale celebrazione dell’armonia fra specie umana e Natura (nota come Shan shui), restituisce la montagna quale richiamo alla consapevolezza nei confronti di politiche consumistiche basate sul profitto e dei conseguenti disastri socio-ambientali.

description: We construct new non-extremal rotating black hole solutions in SO(6) gauged five-dimensional supergravity. Our solutions are the first such examples in which the two rotation parameters are independently specifiable, rather than being set equal. The black holes carry charges for all three of the gauge fields in the U(1)^3 subgroup of SO(6), albeit with only one independent charge parameter. We discuss the BPS limits, showing in particular that these include the first examples of regular supersymmetric black holes with independent angular momenta in gauged supergravity. We also find non-singular BPS solitons. Finally, we obtain another independent class of new rotating non-extremal black hole solutions with just one non-vanishing rotation parameter, and one non-vanishing charge.

It is a story of people, changing times and economies made manifest in a particular type of house. And finally, it is the story of an architectural form humble in stature yet powerful in image and fertile in its variety. This then is my thesis, the bungalow as a vernacular phenomenon, a social expression and an architectural fashion. It is exciting to me, not for its event, but for its historical and social involvement, and for the vigor of its style. The destiny of our modern architectural achievements can be seen through this window and the revolution of our profession, the denigration of academic eclecticism in the first half of this century, cannot be a question of appropriateness or fit, because many of its ideals and attitudes lay pregnant in the popularity of the bungalow twenty years earlier
Development of a DNA based diagnostic assay for the detection and differentiation of pathogenic fusarium oxysporum isolates from conifers in the Pacific Northwest

description: Fusarium oxysporum is commonly associated with a variety of diseases in bare-root conifer nurseries. The identification of F. oxysporum typically requires considerable expertise because of the morphological similarity of many Fusarium species. Furthermore, different isolates of F. oxysporum may or may not be pathogenic. Among pathogens, a large degree of variation in virulence occurs. There were two primary objectives of this work. The first was to continue the development of a previously described DNA-based diagnostic assay which relies on restriction fragment length polymorphisms (RFLPs) within the histone-H3 encoding gene to identify several Fusarium species, including F. oxysporum. The second was to expand the capabilities of the assay to differentiate pathogenic and nonpathogenic isolates of F. oxysporum, or at least opposite ends of the virulence spectrum. To confirm the utility of the DNA-based diagnostic, blind tests were performed using a variety of Fusarium species and fungi commonly isolated from nursery environments. Genetic diversity within tissue and soil subpopulations of F. oxysporum was examined at two nurseries in the state of Oregon to determine the degree of genetic differentiation among nursery populations. To screen for genetic markers associated with virulence, amplified fragment length polymorphisms (AFLPs) derived from 9 different primers were compared to the phenotype of 24 isolates of F. oxysporum selected for their high or low virulence. During the course of this work, evidence that suggests F. oxysporum is a complex of species has accumulated. Although this complicated the screening process, within the limited set of high and low virulence isolates studied, a large number of markers does allow separation of high and low virulence isolates. There is small, but significant, genetic differentiation of the Bend and Medford populations. The relatively low level of differentiation suggests that either the populations at the two sites originated from the same source, or contaminated material moves between the two sites. All of the available data suggest that F. oxysporum has a clonal population structure. Such a population is well suited to DNA-based diagnostic assays.

description: It is challenging to parameterize the force field for calcium ions (Ca2+) in calcium-binding proteins because of their unique coordination chemistry that involves the surrounding atoms required for stability. In this work, we observed wide variation in Ca2+ binding loop conformations of the Ca2+-binding protein calmodulin (CaM), which adopts the most populated ternary structures determined from the MD simulations, followed by ab initio quantum mechanical (QM) calculations on all twelve amino acids in the loop that coordinate Ca2+ in aqueous solution. Ca2+ charges were derived by fitting to the electrostatic potential (ESP) in the context of a classical or polarizable force field (PFF). We discovered that the atomic radius of Ca2+ in conventional force fields is too large for the QM calculation to capture the variation in the coordination geometry of Ca2+ in its ionic form, leading to unphysical charges. Specifically, we found that the fitted atomic charges of Ca2+ in the context of PFF depend on the coordinating geometry of electronegative atoms from the amino acids in the loop. Although nearby water molecules do not influence the atomic charge of Ca2+, they are crucial for compensating for the coordination of Ca2+ due to the conformational flexibility in the EF-hand loop. Our method advances the development of force fields for metal ions and protein binding sites in dynamic environments.

description: Two-loop effects on the right-handed neutrino masses can have an impact on the low-energy phenomenology, especially when the right-handed neutrino mass spectrum is very hierarchical at the cut-off scale. In this case, the physical masses of the lighter right-handed neutrinos can be dominated by quantum effects induced by the heavier ones. Further, if the heaviest right-handed neutrino mass is at around the Planck scale, two-loop effects on the right-handed neutrino masses generate, through the seesaw mechanism, an active neutrino mass which is in the ballpark of the experimental values. In this paper we investigate extensions of the Planck-scale lepton number breaking scenario by additional Higgs doublets (inert or not). We find that under reasonable assumptions these models lead simultaneously to an overall neutrino mass scale and to a neutrino mass hierarchy in qualitative agreement with observations.

description: In this paper we propose a low-energy parametrization of the two right-handed neutrino model, and discuss the prospects to determine experimentally these parameters in supersymmetric scenarios. In addition, we present exact formulas to reconstruct the high-energy leptonic superpotential in terms of the low-energy observables. We also discuss limits of the three right-handed neutrino model where this procedure applies.

description: We study the interaction of Rayleigh and shear horizontal surface acoustic waves (SAWs) with spin waves in thin Ni films on a piezoelectric LiTaO$_3$ substrate, which supports both SAW modes simultaneously. Because Rayleigh and shear horizontal modes induce different strain components in the Ni thin films, the symmetries of the magnetoelastic driving fields, of the magnetoelastic response, and of the transmission nonreciprocity differ for both SAW modes. Our experimental findings are well explained by a theoretical model based on a modified Landau--Lifshitz--Gilbert approach. We show that the symmetries of the magnetoelastic response driven by Rayleigh- and shear horizontal SAWs complement each other, which makes it possible to excite spin waves for any relative orientation of magnetization and SAW propagation direction and, moreover, can be utilized to characterize surface strain components of unknown acoustic wave modes.

description: We report Cousins R-band monitoring of the high-redshift (z=4.40) radio quiet quasar Q 2203+292 from May 1999 to October 2007. The quasar shows maximum peak-to-peak light curve amplitude of ~0.3 mag during the time of our monitoring, and ~0.9 mag when combined with older literature data. The rms of a fit to the light curve with a constant is 0.08 mag and 0.2 mag, respectively. The detected changes are at ~3-sigma level. The quasar was in a stable state during the recent years and it might have undergone a brightening event in the past. The structure function analysis concluded that the object shows variability properties similar to those of the lower redshift quasars. We set a lower limit to the Q 2203+292 broad line region mass of 0.3-0.4 M_odot. Narrow-band imaging search for redshifted Ly_alpha from other emission line objects at the same redshift shows no emission line objects in the quasar vicinity.

description: We study the effects of quantum fluctuations on excitation spectra in the two-dimensional Heisenberg antiferromagnet by means of the 1/S expansion. We calculate the spin-wave dispersion and the transverse dynamical structure factor up to the second order of 1/S in comparison with inelastic neutron scattering experiments. The spin-wave energy at momentum $(π,0)$ is found to be about 2% smaller than that at $(π/2,π/2)$ due to the second-order correction. In addition, we study the dimensional crossover from two dimensions to one dimension by weakening exchange couplings in one direction. It is found that the second-order correction becomes large with approaching the quasi-one dimensional situation and makes the spin-wave energy approach to the des Cloizeaux-Pearson boundary for $S=1/2$. The transverse dynamical structure factor is also calculated up to the second order of 1/S. It is shown that the intensity of spin-wave peak is strongly reduced while the intensity of three-spin-wave continuum becomes large and exceeds that of the spin-wave peak in the quasi-one dimensional situation.
