description: We develop a new method for obtaining bounds on the negative eigenvalues of self-adjoint operators B in terms of a Schatten norm of the difference of the semigroups generated by A and B, where A is an operator with non-negative spectrum. Our method is based on the application of the Jensen identity of complex function theory to a suitably constructed holomorphic function, whose roots are in one-to-one correspondence with the negative eigenvalues of B. Applying our abstract results, together with bounds on Schatten norms of semigroup differences obtained by Demuth and Van Casteren, to Schroedinger operators, we obtain inequalities on moments of the sequence of negative eigenvalues, which are different from the Lieb-Thirring inequalities.

description: Superconductivity was recently observed in CrAs as the helimagnetic order is suppressed by applying pressure, suggesting possible unconventional superconductivity. To reveal the nature of the superconducting order parameter of CrAs, here we report the angular dependence of the upper critical field under pressure. Upon rotating the field by 360 degrees in the $bc$-plane, six maxima are observed in the upper critical field, where the oscillations have both six-fold and two-fold symmetric components. Our analysis suggests the presence of an unconventional odd-parity spin triplet state.

description: The pairing-plus-quadrupole Hamiltonian is diagonalized in a symmetry restored basis, i.e., the triaxial quasiparticle-states with angular momentum and particle number projections, and applied for chiral doublet bands in 128Cs. The observed energy spectra and electromagnetic transition probabilities are reproduced well without introducing any parameter. The orientation of the angular momentum in the intrinsic frame is investigated by the distributions of its components on the three principle axes as well as those of its tilted angles. The evolution of the chirality with spin is illustrated and the chiral geometry is demonstrated in the angular momentum projected model for the first time.

description: We introduce and analyze models for the propagation of malware in pure D2D networks given via stationary Cox--Gilbert graphs. Here, the devices form a Poisson point process with random intensity measure λ, Λ where Λ is stationary and given, for example, by the edge-length measure of a realization of a Poisson--Voronoi tessellation that represents an urban street system. We assume that, at initial time, a typical device at the center of the network carries a malware and starts to infect neighboring devices after random waiting times. Here we focus on Markovian models, where the waiting times are exponential random variables, and non-Markovian models, where the waiting times feature strictly positive minimal and finite maximal waiting times. We present numerical results for the speed of propagation depending on the system parameters. In a second step, we introduce and analyze a counter measure for the malware propagation given by special devices called white knights, which have the ability, once attacked, to eliminate the malware from infected devices and turn them into white knights. Based on simulations, we isolate parameter regimes in which the malware survives or is eliminated, both in the Markovian and non-Markovian setting.

description: Background: Caring for cancer patients can take a toll on the emotional health of oncology nurses, which may lead to compassion fatigue, resulting in decreased quality of nursing care, absenteeism and decreased retention of staff. Aim: The aim of this study was to describe compassion fatigue from the perspective of oncology nurses. This study is part of a larger mixed-methods action research study to develop an in-facility intervention to manage compassion fatigue in oncology nurses. Setting: This study was conducted at Durban, KwaZulu-Natal, South Africa. Methods: The research setting comprised one state hospital (with oncology clinics and wards), a private hospital (with oncology wards) and a hospice in Durban, KwaZulu-Natal, South Africa. Semi-structured individual interviews (guided by Figley’s Compassion Fatigue Process, 2005) were conducted with eight participants. Data were analysed using manifest content analysis. Results: Five categories emerged from the data, namely, emotional connection, emotional fatigue, emotional loss, blurring boundaries and acceptance. Conclusion: The findings revealed that oncology nurses are affected emotionally in caring for their patients, thus making them prone to compassion fatigue. Oncology nurses need to acknowledge compassion fatigue and be able to self-reflect on how they are managing (both positively and negatively) with the stressors encountered in the oncology wards or units.
Non-perturbative constraints on the quark and ghost propagators

description: In QCD both the quark and ghost propagators are important for governing the non-perturbative dynamics of the theory. It turns out that the dynamical properties of the quark and ghost fields impose non-perturbative constraints on the analytic structure of these propagators. In this work we explicitly derive these constraints. In doing so we establish that the corresponding spectral densities include components which are multiples of discrete mass terms, and that the propagators are permitted to contain singular contributions involving derivatives of $δ(p)$, both of which are particularly relevant in the context of confinement.

Density Perturbations from Two-field Inflation
Creators: name: Wands, David
name: Garcia-Bellido, Juan
Publisher: name: arXiv
Year: 1996
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We discuss metric perturbations produced during a period of inflation in the early universe where two scalar fields evolve. The final scalar perturbation spectrum can be calculated in terms of the perturbed expansion along neighbouring trajectories in field-space. In the usual single field case this is fixed by the values of the fields at horizon-crossing, but in the presence of more than one field there is no longer a unique slow-roll trajectory. The presence of entropy as well as adiabatic fluctuations means that the super-horizon-sized metric perturbation $ζ$ may no longer be conserved and the evolution must be integrated along the whole of the subsequent trajectory. In general there is an inequality between the ratio of tensor to scalar perturbations and the tilt of the gravitational wave spectrum, which becomes an equality when only adiabatic perturbations are possible and $ζ$ is conserved.

“To be healthy to me is to be free”: how discourses of freedom are used to construct healthiness among young South African adults

subject: FOS: Health sciences

description: Purpose: Healthiness is constructed, in Western culture, as a moral ideal or supervalue. This paper will interrogate the assumption that health and the pursuit of healthiness is always and unquestionably positive, by exploring how discourses of health and freedom interact to reinforce the current inequalities and detract from social transformation. Method: Twenty young South African adults were interviewed about their understandings and experiences of health. These discussions were analysed using Foucauldian discourse analysis. Results: Participants constructed healthiness as facilitating the experience of freedom, while at the same time being dependent on a personal orientation towards freedom (as opposed to merely submitting to dominant health authorities). Freedom discourses also played a role in connecting health to neoliberal discourses idealizing economic productivity and hard work. Participants were able to construct a self that is active, productive, valuable, hopeful, and self-assured when talking about health using discourses of freedom. However, these discourses also functioned to moralise and idealise healthiness, which contributed to blaming poor health on its sufferers. Conclusion: Health/freedom discourses can further reinforce the neoliberal value of individual responsibility by constructing self-improvement and self-work as the solution to ill-health, thereby contributing to victim-blaming and weakening support for public health interventions.

For this, we construct invariants attached to a given hypersurface that serve as obstructions to embeddability. We further study the embeddability problem for real-analytic submanifolds of higher codimension and answer a question by Forstnerič.

description: We present the first spectroscopic measurement of multiple rest-frame optical emission lines at $z>4$. During the MOSFIRE Deep Evolution Field (MOSDEF) survey, we observed the galaxy GOODSN-17940 with the Keck I/MOSFIRE spectrograph. The K-band spectrum of GOODSN-17940 includes significant detections of the [OII]$λλ3726,3729$, [NeIII]$\lambda3869$, and H$γ$ emission lines and a tentative detection of H$δ$, indicating $z_{\rm{spec}}=4.4121$. GOODSN-17940 is an actively star-forming $z>4$ galaxy based on its K-band spectrum and broadband spectral energy distribution. A significant excess relative to the surrounding continuum is present in the Spitzer/IRAC channel 1 photometry of GOODSN-17940, due primarily to strong H$α$ emission with a rest-frame equivalent width of $\mbox{EW(H}α)=1200$ Å. Based on the assumption of $0.5 Z_{\odot}$ models and the Calzetti attenuation curve, GOODSN-17940 is characterized by $M_*=5.0^{+4.3}_{-0.2}\times 10^9 M_{\odot}$. The Balmer decrement inferred from H$α$/H$γ$ is used to dust correct the H$α$ emission, yielding $\mbox{SFR(H}α)=320^{+190}_{-140} M_{\odot}\mbox{ yr}^{-1}$. These $M_*$ and SFR values place GOODSN-17940 an order of magnitude in SFR above the $z\sim 4$ star-forming "main sequence." Finally, we use the observed ratio of [NeIII]/[OII] to estimate the nebular oxygen abundance in GOODSN-17940, finding $\mbox{O/H}\sim 0.2 \mbox{ (O/H)}_{\odot}$. Combining our new [NeIII]/[OII] measurement with those from stacked spectra at $z\sim 0, 2, \mbox{ and } 3$, we show that GOODSN-17940 represents an extension to $z>4$ of the evolution towards higher [NeIII]/[OII] (i.e., lower $\mbox{O/H}$) at fixed stellar mass. It will be possible to perform the measurements presented here out to $z\sim 10$ using the James Webb Space Telescope.

description: In this Letter we present calibrated observations of the average mass of galaxies with 22< I < 25 in the Hubble Deep Field. We measure the mean mass profile using the statistical gravitational lens distortion of faint blue background galaxies, based on 2221 foreground-background pairs. The observed weak lensing distortion is calibrated via full 3-D simulations and other HST data on a foreground cluster of known mass. Inside a projected radius of 5 arcsec we find a 3σdetection of shear. Fitting to an isothermal mass distribution, we find a shear of 0.066^{+0.018}_{-0.019} at a radius of 2\arcsec\ (\sim 8 ~ h^{-1} kpc). The (1σ) limits on the parameters for the truncated isothermal model are σ_v =185^{+30}_{-35} km s^{-1}, r_{outer} \ge 15 ~ h^{-1} kpc, and r_{core}= 0.6^{+1.3}_{-0.6} ~ h^{-1} kpc. This corresponds to an average galaxy mass interior to 20 h^{-1} kpc of 5.9^{+2.5}_{-2.7}\times 10^{11} h^{-1} M_\odot. Inside 10 h^{-1} kpc, we find an average rest-frame V band mass-to-light ratio of 11.4^{+6.0}_{-6.7} h (M/L_V)_\odot.

description: Let f be an integer greater than one. We study three progressively finer equivalence relations on closed 3-manifolds generated by Dehn surgery with denominator f: weak f-congruence, f-congruence, and strong f-congruence. If f is odd, weak f-congruence preserves the ring structure on cohomology with Z_f-coefficients. We show that strong f-congruence coincides with a relation previously studied by Lackenby. Lackenby showed that the quantum SU(2) invariants are well-behaved under this congruence. We strengthen this result and extend it to the SO(3) quantum invariants. We also obtain some corresponding results for the coarser equivalence relations, and for quantum invariants associated to more general modular categories. We compare S^3, the Poincare homology sphere, the Brieskorn homology sphere Sigma(2,3,7) and their mirror images up to strong f-congruence. We distinguish the weak f-congruence classes of some manifolds with the same Z_f-cohomology ring structure.

description: This article gives a brief overview of the aspects of the new entrepreneur’s personal environment, and who it can affect when their ambitions or aspirations become obsessive and compulsive. Some of these effects that entrepreneurship can have on families, can lead to neglect of minor children, spouse, domestic partnership, and personal environmental obligations. Other examples also can lead a family to financial ruin as well as the entrepreneur themselves into a whirlwind of mental anxiety; this can also lead to more devastating health issues such as mood swings and depression. This article takes a deeper look at the effects of entrepreneurship from the mental stability to the rise and personal obligations of the female entrepreneur. This article will also take a look at the journey of the female entrepreneur, and how the evolution of the successful female business executive has managed to merge both their personal environments as well as their business environment.

description: It has been found that the zero mode of a five-dimensional Elko spinor could be localized on branes by introducing a Yukawa-type coupling between the Elko spinor and the background scalar field or the Ricci scalar. However, the Yukawa-type coupling is not appropriate for all brane models. In this paper, we explore other localization mechanism for the Elko spinor by introducing the non-minimal coupling $f(ϕ)\mathfrak{L}_{Elko}$ between the five-dimensional Elko spinor and the background scalar field. We give the general expressions of the Elko zero mode and the function $f(ϕ)$. Through two thick brane models and three concrete examples, we show that the Elko zero mode can be localized on the branes by this new mechanism. This provides us more possibilities of localizing the Elko zero mode.

description: This qualitative case study examines how a preservice English as an Additional Language (EAL) teacher from the Faculty of Education at a large Melbourne-based university learned to scaffold EAL learning during a two-week practicum in a secondary school and the factors shaping his cognition. The data sources include individual interviews, oral reflections on lessons and recordings of those same lessons. The study was underpinned by a sociocultural perspective on scaffolding and van de Pol, Volman and Beishuizen’s (2010) framework for analysing scaffolding, which is based on a synthesis of previous models and findings. The findings indicate that the preservice teacher implemented a number of scaffolding strategies during the EAL practicum. The use of these strategies was shaped by the preservice teacher’s theoretical knowledge of scaffolding and belief about its importance, which he gained from the teacher education coursework and his prior practicum experience. Learning within practice was also found to be important in his cognition of scaffolding as through the practicum he developed knowledge about his students’ abilities and their difficulties in learning EAL, which are the basis for his contingent scaffolding strategies. Based on the findings, the paper suggests that instructional scaffolding is an important area of professional learning, especially for teachers working with EAL students, and needs to be explicitly built into teacher education in both coursework and the teaching practicum.

description: Introduction: rhupus is a rheumatologic disease whiaaach meets the criteria of the rheumatoid arthritis (RA) and the systemic lupus erythematous (SLE). We are reporting the first Malagasy case. Observation: the patient V., 37 years old, was treated for a rheumatoid arthritis for a year with positive ACPA and Rheumatoid Factory, and diffuse squeezing in the proximal interphalangeal joints. The patient had a generalized pitting edema associated with a dyspnea and oliguria. Laboratory studies showed an anemia of 9g/dl, an erythrocyte sedimentation rate of 120mm/h. The creatinine of 145umol/l, and a 24 hour urine protein was 8 g/l. The anti-nuclear antibody (ANA) was positive of 1280 and a positif DNA natif. The anti-Sm and anti-SSA were positive. The patient had a SLE panel with renal and cardiac failure confirmed by Doppler echocardiography. The diagnosis of rhupus is raised in front of the presence of 4 criteria from the Systemic lupus International Collaborating Clinics (SLICC) for the SLE, and 4 other criteria from the American College of Rheumatology (ACR) for the RA. Conclusion: the coexistence of the two connective tissue diseases such as SLE and RA is a rare phenomenon. The etiopathogeny is still an under-treated disease which makes its treatment management often rough handling.
description: Introduction : le rhupus est une maladie rhumatologique rare qui répond à la fois aux critères de classification de la polyarthrite rhumatoïde (PR) et du lupus érythémateux systémique (LES). Nous en rapportons un premier cas Malgache. Observation : Mme V., 37 ans, était diagnostiquée initialement comme atteinte d’une polyarthrite rhumatoïde (PR) devant l’association de polyarthrite chronique, un ACPA et FR positifs, et des pincements articulaires sur la radiographie des mains. Un an après ce tableau initial, elle développait un œdème généralisé associé à une dyspnée et une oligurie. La NFS a montré une anémie microcytaire à 9g/dl, une VS à 120mm/h, une créatininémie à 145umol/l, et une protéinurie de 24h à 8 g/l. L’anticorps anti-nucléaire (ANN) était élevé à 1280 moucheté et un anti-DNA natif était positif. Les anti-Sm et anti-SSA étaient positifs. La patiente présentait ainsi un tableau de Lupus Erythémateux Systémique (LES) avec atteinte rénale et cardiaque confirmée à l’echodoppler. Le diagnostic de rhupus est évoqué devant la présence de 4 critères du Systemic lupus International Collaborating Clinics (SLICC) pour le LES et 4 critères de l’American College of Rheumatology (ACR) pour la PR. Conclusion : La coexistence de deux connectivites comme le LES et la PR est un phénomène rare. L’étiopathogénie est encore méconnue et la prise en charge mérite des discussions.

description: The magnetic cataclysmic variable DQ Herculis was observed with the Faint Object Spectrograph onboard the Hubble Space Telescope (HST) over four consecutive satellite orbits, including the first observation in the UV of DQ Her through eclipse minimum. Strong emission in N V, C IV, Si IV, and He II and weak emission in O I, S III, Ni II, N IV, Si III, and C III was seen. Time resolved spectroscopy was obtained over 3 orbits with the G160L grating. At the eclipse minimum, the UV continuum was completely eclipsed for < 5% of the orbital period. This implies that the UV continuum emission region is very compact. By contrast, none of the emission lines were completely eclipsed, most notably C IV which dropped by only ~75%. DQ Her is known to have intermittent pulsations in the optical and UV at a period of 71 s, due to the rotation of the accreting white dwarf. As in our previous observations, the UV continuum and the C IV emission show sporadic 71 s pulsations. The mechanism(s) which determine the pulsation amplitudes are clearly complex. The strong emission lines and continuum were auto-correlated during the first and third HST orbits and all show a variability timescale of ~160 s. The intensities of these lines were also cross-correlated with the continuum and show a strong correlation with the continuum with a timelag of < 4 s. The data during the fourth HST orbit were collected with the G190H grating (1600-2350 Angstroms with 1.5 Angstrom spectral resolution) in standard spectroscopy mode (240 s time resolution). These observations resolve He II 1640 into a broad (1,400 km/s), asymmetric line.

description: The equation of state of hot hadronic matter is obtained, by taking into account the contribution of the massive states with the help of the resonance spectrum $τ(m)\sim m^3$ justified by the authors in previous papers. This equation of state is in agreement with that provided by the low-temperature expansion for the pion intracting gas. It is shown that in this picture the deconfinement phase transition is absent, in agreement with lattice gauge calculations which show the only phase transition of chiral symmetry restoration. The latter is modelled with the help of the restriction of the number of the effective degrees of freedom in the hadron phase to that of the microscopic degrees of freedom in the quark-gluon phase, through the corresponding truncation of the hadronic resonance spectrum, and the decrease of the effective hadron masses with temperature, predicted by Brown and Rho. The results are in agreement with lattice gauge data and show a smooth crossover in the thermodynamic variables in a temperature range $\sim 50$ MeV.

description: The Internet of Things (IoT) sparks a whole new world of embedded applications. Most of these applications are based on deeply embedded systems that have to operate on limited or unreliable sources of energy, such as batteries or energy harvesters. Meeting the energy requirements for such applications is a hard challenge, which threatens the future growth of the IoT. Software has the ultimate control over hardware. Therefore, its role is significant in optimizing the energy consumption of a system. Currently, programmers have no feedback on how their software affects the energy consumption of a system. Such feedback can be enabled by energy transparency, a concept that makes a program's energy consumption visible, from hardware to software. This paper discusses the need for energy transparency in software development and emphasizes on how such transparency can be realized to help tackling the IoT energy challenge.

description: We show that the recently introduced L1TV functional can be used to explicitly compute the flat norm for co-dimension one boundaries. While this observation alone is very useful, other important implications for image analysis and shape statistics include a method for denoising sets which are not boundaries or which have higher co-dimension and the fact that using the flat norm to compute distances not only gives a distance, but also an informative decomposition of the distance. This decomposition is made to depend on scale using the "flat norm with scale" which we define in direct analogy to the L1TV functional. We illustrate the results and implications with examples and figures.

description: We calculate quantum loop corrections to the stress-energy flux caused by moving mirrors. We consider massless, self-interacting, $ϕ^4$, real scalar theory. In these calculations we encounter a new and quite unexpected subtleties due to the absence of global hyperbolicity in the presence of mirrors. We attempt to clearly phrase as many as possible hidden assumptions and complications that appear along the course of the solution of the problem in question. On top of that we find that quantum loop corrections to the stress-energy flux are growing with time and are not suppressed in comparison with the semi-classical contributions. Thus, we observe the break down of the perturbation theory, discuss its physical origin and ways to deal with such a situation. As a byproduct we observe a similarity of the problem in question with that for the minimally coupled, massless scalar field in de Sitter space.

description: Το τένις είναι ένα άθλημα με ιδανική συμμετοχή του σώματος και του πνεύματος. Το πρόγραμμα «Play and Stay», που προτείνει η Διεθνής Ομοσπονδία Αντισφαίρισης, καθοδηγεί τους προπονητές να τροποποιήσουν τους κανόνες του παιχνιδιού και να χρησιμοποιήσουν συγκεκριμένο υλικοτεχνικό εξοπλισμό, με σκοπό να μπορούν οι συμμετέχοντες να αρχίζουν το παιχνίδι από το πρώτο μάθημα, κάνοντάς το διασκεδαστικό και ενδιαφέρον, «κρατώντας» ουσιαστικά τους αρχάριους παίκτες στο παιχνίδι. Σκοπός της παρούσας έρευνας ήταν η εξέταση της επίδρασης του προγράμματος «Play and Stay» στην εκμάθηση των βασικών δεξιοτήτων του τένις (backhand, forehand και service) και στην αντιλαμβανόμενη ικανοποίηση των αρχάριων μαθητών. Επίσης ο έλεγχος των διαφορών στην απόδοση και μάθηση, καθώς και στην αντιλαμβανόμενη ικανοποίηση από το πρόγραμμα μεταξύ αγοριών και κοριτσιών. Το δείγμα της έρευνας αποτέλεσαν 62 μαθητές (2 τμήματα) ηλικίας 11. Κάθε τμήμα χωρίσθηκε τυχαία σε δυο ομάδες, την ομάδα Α (πειραματική) και την ομάδα Β (ελέγχου). Η πειραματική ομάδα ακολούθησε το πρόγραμμα «Play and Stay» και η ομάδα ελέγχου τον παραδοσιακό τρόπο διδασκαλίας των τριών βασικών δεξιοτήτων του τένις. Έγιναν τέσσερις μετρήσεις: αρχική, την αμέσως επόμενη μέρα (έλεγχος αξιοπιστίας), τελική και διατήρησης. Επίσης στους μαθητές και των δυο ομάδων μοιράστηκαν ερωτηματολόγια για τη διερεύνηση του βαθμού ικανοποίησής τους. Από την επεξεργασία των αποτελεσμάτων προέκυψε ότι ανά ξεχωριστό παράγοντα τεχνικής και αποτελέσματος των τριών χτυπημάτων και ως προς την αντλούμενη ικανοποίηση από το πρόγραμμα, η πειραματική ομάδα ήταν καλύτερη από την ομάδα ελέγχου. Συμπεραίνεται ότι η μέθοδος «Play and Stay» που προτείνει η Διεθνής Ομοσπονδία Αντισφαίρισης είναι πιο αποτελεσματική σε όλο το φάσμα της διδασκαλίας.

description: We note that current observational evidence strongly favors a conventional recombination of ionized matter subsequent to redshift z=1200, followed by reionization prior to redshift z=5 and compute how this would have occurred in a standard scenario for the growth of structure. Extending prior semi-analytic work, we show by direct, high-resolution numerical simulations (of a COBE normalized CDM+Lambda model) that reheating, will occur in the interval 15>z>7, followed by reionization and accompanied by a significant increase in the Jeans mass. However, the evolution of the Jeans mass does not significantly affect star formation in dense, self-shielded clumps of gas, which are detached from the thermal evolution of the rest of the universe. On average, the growth of the Jeans mass tracks the growth of the nonlinear mass scale, a result we suspect is due to nonlinear feedback effects. Cooling on molecular hydrogen leads to a burst of star formation prior to reheating which produces Population III stars with Omega_* reaching 10^{-5.5} and Z/Z_sun reaching 10^{-3.7} by z=14. Star formation subsequently slows down as molecular hydrogen is depleted by photo-destruction and the rise of the temperature. At later times, z<10, when the characteristic virial temperature of gas clumps reach 10,000 degrees, star formation increases again as hydrogen line cooling become efficient. Objects containing Pop III stars accrete mass with time and, as soon as they reach 10,000 K virial temperature, they engage in renewed star formation and turn into normal Pop II objects having an old Pop III metal poor component.

On Renormalized Strong-Coupling Quenched QED in Four Dimensions

description: We study renormalized quenched strong-coupling QED in four dimensions in arbitrary covariant gauge. Above the critical coupling leading to dynamical chiral symmetry breaking, we show that there is no finite chiral limit. This behaviour is found to be independent of the detailed choice of photon-fermion proper vertex in the Dyson-Schwinger equation formalism, provided that the vertex is consistent with the Ward-Takahashi identity and multiplicative renormalizability. We show that the finite solutions previously reported lie in an unphysical regime of the theory with multiple solutions and ultraviolet oscillations in the mass functions. This study supports the assertion that in four dimensions strong coupling QED does not have a continuum limit in the conventional sense.

X-Ray Emission Line Imaging and Spectroscopy of Tycho's Supernova Remnant

description: We present X-ray images of Tycho's supernova remnant in emission line features of Mg, Si, S, Ar, Ca, and Fe, plus the continuum, using data obtained by the imaging spectrometers onboard the ASCA X-ray satellite. All the images show the shell-like morphology characteristic of previously obtained broad-band X-ray images, but are clearly distinct from each other. We use image reconstruction techniques to achieve a spatial resolution of ~0.8'. Line intensity ratios are used to make inferences about the remnant's physical state, on average for the entire remnant, and with angular position around the rim. The average temperature (T) of the Si and S ejecta in the remnant is (0.8-1.1) X 10^7 K and the average ionization age (nt) is (0.8-1.3) X 10^11 cm^-3 s. For a constant nt, the observed relative brightness variations of Si and S line image profiles with azimuthalangle imply differences of roughly a factor of 1.3-1.8 in the temperature. We compare the radial brightness profiles of our images to simple geometrical models, and find that a spherical emitting geometry is favored over a torus. A spherical geometry is further supported by the absence of systematic Doppler shifts across the remnant. The radial fit results also suggest that some radial mixing of the ejecta has occurred. However, the azimuthally averaged Fe K image peaks at a markedly lower radius than the other images. The average Fe K / Fe L line intensity ratio and the position of the Fe K energy centroid support a T several times higher and an nt approx. a factor of ten lower than for the other elements, and imply that the Fe ejecta must have retained some of its stratification. Although many of the features in the 4-6 keV X-ray continuum correspond to those in the radio, there is no obvious correlation between the relative brightness in these bands.

description: We explore jet physics in hadron collisions using the parton shower event generator Deductor. Of particular interest is the one jet inclusive cross section dsigma/dpT for jets of very high pT. Compared to the Born level, the cross section decreases substantially because of pT loss from the jet during showering. We compare to the same effect in Pythia and Dire. The cross section then increases substantially because of the summation of threshold logarithms included in Deductor. We also study the cross section to have a gap with no jets between two hard jets that are widely separated in rapidity. Here we compare Deductor with virtuality based ordering with Deductor with kT ordering and we check whether adding an underlying event and hadronization has a significant effect beyond that found with just a parton shower.
