description: Beauty production in events containing two muons in the final state has been measured with the ZEUS detector at HERA using an integrated luminosity of 114 pb-1. A low transverse-momentum threshold for muon identification, in combination with the large rapidity coverage of the ZEUS muon system, gives access to almost the full phase space for beauty production. The total cross section for beauty production in ep collisions at sqrt(s)= 318 GeV has been measured to be sigma_tot(ep -> bbbar X) = 13.9 +- 1.5(stat.) +4.0 -4.3(syst.) nb. Differential cross sections and a measurement of bbbar correlations are also obtained, and compared to other beauty cross-section measurements, Monte Carlo models and next-to-leading-order QCD predictions.

Eruptions of Magnetic Ropes in Two Homologous Solar Events on 2002 June 1 and 2: a Key to Understanding of an Enigmatic Flare

description: The goal of this paper is to understand the drivers, configurations, and scenarios of two similar eruptive events, which occurred in the same solar active region 9973 on 2002 June 1 and 2. The June 2 event was previously studied by Sui, Holman, and Dennis (2006, 2008), who concluded that it was challenging for popular flare models. Using multi-spectral data, we analyze a combination of the two events. Each of the events exhibited an evolving cusp-like feature. We have revealed that these apparent ``cusps'' were most likely mimicked by twisted magnetic flux ropes, but unlikely to be related to the inverted Y-like magnetic configuration in the standard flare model. The ropes originated inside a funnel-like magnetic domain whose base was bounded by an EUV ring structure, and the top was associated with a coronal null point. The ropes appear to be the major drivers for the events, but their rise was not triggered by reconnection in the coronal null point. We propose a scenario and a three-dimensional scheme for these events in which the filament eruptions and flares were caused by interaction of the ropes.

A new method of phosphorylation and the synthesis of some phosphate esters of biological interest
Creators: name: Moffatt, John Gilbert
Publisher: name: University of British Columbia
Year: 2012

description: Tetra-p-nitrophenyl pyrophosphate, generated in situ by the reaction of di-p-nitrophenyl phosphate with di-p-tolyl carbodiimide in anhydrous dioxane, has been shown to be a new and powerful phosphorylating agent, it has been used for the phosphorylation of various aliphatic alcohols and carbohydrate derivatives, particularly nucleosides, as well as of aliphatic amines and mercaptans. The removal of the protecting groups from the initially formed di-p-nitrophenyl alkyl phosphates has been accomplished by both alkaline hydrolysis and catalytic hydrogenolysis. Various other chemical reactions of the intermediate neutral esters, as typified by di-p-nitrophenyl methyl phosphate, have been studied in considerable detail. Included in these are: mild alkaline hydrolysis, partial hydrogenolysis, the action of anhydrous amines, acidic hydrolysis, base catalysed transesterification, and reductive cleavage with sodium in liquid ammonia. The method has been specifically applied, to the phosphorylation of 2',3'-0-isopropylidine guanosine and has led to the first efficient synthesis of the biologically interesting guanosine-5'-phosphate. Also the enzymatic-ally useful guanosine-5’-mono-p-nitrophenyl phosphate and uridine-5’-mono-p-nitrophenyl phosphate have been prepared and the formation of 3,5’-cyclo-guanosine quaternary salts observed. Several synthetic routes have been developed for the synthesis of 1,2-0-isopropylidine-D-xylofuranose-3,5-cyclic phosphate and of D-xylofuranose-3,5-cyclic phosphate. Hot alkaline hydrolysis of the former followed by acidic removal of the isopropylidine group has led to a mixture of D-xylofuranose-5-phosphate and D-xylopyranose-3-phosphate which were separated by ion exchange chromatography. Both products have been fully characterized and the method constitutes the first successful synthesis of D-xylose-3-phosphate. A previously reported isolation of the latter compound has been reexamined and shown to be in error. Reinterpretation of the data has shown the reported compound to be in fact D-xylulose-5-phosphate.

description: Using numerical modeling and a grid of synthetic spectra, we examine the effects that unresolved binaries have on the determination of various stellar atmospheric parameters for SEGUE targets measured using the SEGUE Stellar Parameter Pipeline (SSPP). To model undetected binaries that may be in the SEGUE sample, we use a variety of mass distributions for the primary and secondary stars in conjunction with empirically determined relationships for orbital parameters to determine the fraction of G-K dwarf stars, as defined by SDSS color cuts, that will be blended with a secondary companion. We focus on the G-K dwarf sample in SEGUE as it records the history of chemical enrichment in our galaxy. To determine the effect of the secondary on the spectroscopic parameters, we synthesize a grid of model spectra from 3275 to 7850 K (~0.1 to 1.0 \msun) and [Fe/H]=-0.5 to -2.5 from MARCS model atmospheres using TurboSpectrum. We analyze both "infinite" signal-to-noise ratio (S/N) models and degraded versions, at median S/N of 50, 25 and 10. By running individual and combined spectra (representing the binaries) through the SSPP, we determine that ~10% of the blended G-K dwarf pairs with S/N>=25 will have their atmospheric parameter determinations, in particular temperature and metallicity, noticeably affected by the presence of an undetected secondary. To account for the additional uncertainty from binary contamination at a S/N~10, uncertainties of ~140 K and ~0.17 dex in [Fe/H] must be added in quadrature to the published uncertainties of the SSPP.

description: To investigate the impact of COVID-19 on hospitalization and consequent diabetes-related complications in patients with type 2 diabetes mellitus (diabetes). We conducted a retrospective cohort study of patients with diabetes. Interrupted time series analysis (ITS) was used to analyze the monthly trends in diabetes-related hospitalization rates, including short- and long-term complications, 1-year before and after onset of COVID-19. Persons with diabetes experienced a significant (p < 0.001) rapid drop in monthly hospital admission rates at onset of COVID-19, then rose significantly (p = 0.003) to higher than pre-COVID-19 levels. Older age, lower education, and income levels were associated with higher base-level monthly hospital admission rates and a greater rate reduction at COVID-19 onset. ITS analysis showed monthly hospital admission rates from short-term complications surged to higher level 6 months after COVID-19 onset. Hospital admissions due to long-term complications decreased immediately post-COVID-19, but rose significantly (p < 0.001) to higher than pre-COVID levels, with patients experiencing higher nephropathy, angiography, and dermatological complications post-COVID-19. COVID-19 had a negative impact on diabetes-related hospitalization access, resulting in increased short- and long-term complications. Long-term effects of deferred care due to COVID-19 on diabetes-related complications may persist, emphasizing the need for continued education toward improved diabetes self-management.

description: We use abundances of Ca, O, Na, Al from high resolution UVES spectra of 200 red giants in 17 globular clusters (GCs) to investigate the correlation found by Lee et al. (2009) between chemical enrichment from SN II and star-to-star variations in light elements in GC stars. We find that (i) the [Ca/H] variations between first and second generation stars are tiny in most GCs (~0.02-0.03 dex, comparable with typical observational errors). In addition, (ii) using a large sample of red giants in M 4 with abundances from UVES spectra from Marino et al. (2008), we find that Ca and Fe abundances in the two populations of Na-poor and Na-rich stars are identical. These facts suggest that the separation seen in color-magnitude diagrams using the U band or hk index (as observed in NGC 1851 by Han et al. 2009) are not due to Ca variations. Small differences in [Ca/H] as associated to hk variations might be due to a small systematic effect in abundance analysis, because most O-poor/Na-rich (He-rich) stars have slightly larger [Fe/H] (by 0.027 dex on average, due to decreased H in the ratio) than first generation stars and are then located at redder positions in the V,hk plane. While a few GCs (M 54, omega Cen, M 22, maybe even NGC 1851) do actually show various degree of metallicity spread, our findings eliminate the need of a close link between the enrichment by core-collapse SNe with the mechanism responsible for the Na-O anticorrelation.

Anomaly-Mediated Supersymmetry Breaking Demystified

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We reinterpret anomaly-mediated supersymmetry breaking from a field-theoretic perspective in which superconformal anomalies couple to either the chiral compensator or the $U(1)_R$ vector superfield. As supersymmetry in the hidden sector is spontaneously broken by non-vanishing vacuum expectation values of the chiral compensator F-term and/or the $U(1)_R$ vector superfield D-term, the soft breakdown of supersymmetry emerges in the visible sector. This approach is physically more understandable compared with the conventional approach where the chiral compensator is treated on the same footing as a spurion in gauge-mediated supersymmetry breaking scenario.

description: Viscosupplementation is a viable alternative for managing knee osteoarthritis, showing potential to delay the need for total joint replacement in affected patients. We constructed an economic model that compared viscosupplementation with hylan G-F 20, with available hyaluronic acids, and no viscosupplementation over a 5-year period, from the perspective of the Colombian general health system. Time until total knee replacement, sourced from published literature, informed the model. Costs, including acquisition, administration, and knee replacement surgery, were sourced from the local drug prices database and the Ministry of Health’s integral information system and expressed in USD. Over 5 years, hylan G-F 20 demonstrated a total cost of USD$45,188,523 compared to hyaluronic acids (USD$50,247,826) and no viscosupplementation (USD$27,345,736). Hylan G-F 20 yielded 39,400 total knee replacement-free years, exceeding hyaluronic acid (30,741) and no viscosupplementation (4,280). Cumulative costs per surgery-free patient showed substantial savings, ranging from USD$1,158 to $6,847 for hylan G-F 20, compared to $1,164 to $74,662 for hyaluronic acid and $5,426 to $6,389 for no viscosupplementation. Hylan G-F 20 showed reduced cost per surgery-free patient compared to hyaluronic acids and no viscosupplementation, enhancing knee replacement-free years.

This flare is one of the few in which emission up to energies exceeding 200 keV can be imaged in hard X-rays. Furthermore, we can investigate the spectra of individual sources up to this energy. We discuss and compare the HXR and microwave spectra and morphology. Although the event overall appears to correspond to the standard scenario with magnetic reconnection under an eruptive filament, several of its features do not seem to be consistent with popular flare models. In particular we find that (1) microwave emissions might be optically thick at high frequencies despite a low peak frequency in the total flux radio spectrum, presumably due to the inhomogeneity of the emitting source; (2) magnetic fields in high-frequency radio sources might be stronger than sometimes assumed; (3) sources spread over a very large volume can show matching evolution in their hard X-ray spectra that may provide a challenge to acceleration models. Our results emphasize the importance of studies of sunspot-associated flares and total flux measurements of radio bursts in the millimeter range.

description: In this paper, we present a partial survey of the tools borrowed from tensor algebra, which have been utilized recently in Statistics and Signal Processing. It is shown why the decompositions well known in linear algebra can hardly be extended to tensors. The concept of rank is itself difficult to define, and its calculation raises difficulties. Numerical algorithms have nevertheless been developed, and some are reported here, but their limitations are emphasized. These reports hopefully open research perspectives for enterprising readers.

description: We analyse Spitzer MIPS 24micron observations, and SDSS (DR7) optical broadband photometry and spectra, to investigate the star formation (SF) properties of galaxies residing in the Coma supercluster region. We find that SF in dwarf galaxies is quenched only in the high density environment at the centre of clusters and groups, but passively-evolving massive galaxies are found in all environments, indicating that massive galaxies can become passive via internal processes. We find AGN activity is suppressed in the cluster cores. We present evidence for a strong dependence of the mechanism(s) responsible for quenching SF in dwarf galaxies on the cluster potential. We find a significant increase in the mean EW of Halpha among star-forming dwarf galaxies in the infall regions of the Coma cluster and the core of Abell 1367 with respect to the overall supercluster population, indicative of the infalling dwarf galaxies undergoing a starburst phase. We identify these starburst galaxies as the precursors of the post-starburst k+A galaxies. We find that 11.4% of all dwarf (z mag > 15) galaxies in the Coma cluster and 4.8% in the Abell 1367 have k+A like spectra, while this fraction is just 2.1% when averaged over the entire supercluster region. We show that in the centre of the Coma cluster, the (24-z) colour of galaxies is correlated with their optical (g-r) colour and Halpha emission. By analysing the projected phase space distribution of galaxies detected at 24micron in Coma, we find that the (optically) red 24 micron detected galaxies follow the general distribution of `all' the spectroscopic members, but their (optically) blue counterparts show interesting features, indicative of recent infall.

The nitration and fractionation of whole wood
Creators: name: Elias, Wilma Ethel
Publisher: name: University of British Columbia
Year: 2012

description: In an attempt to develop a method by which the chemical components of whole wood samples could be separated on a quantitative basis, the reactions of gaseous dinitrogen pentoxide with model substances and with acetone-extracted wood have been studied. The crystalline compounds D-mannitol, benzoic acid and D,L-tartaric acid were smoothly nitrated by exposure to an excess of the pentoxide at 0 ± 2° C. and the crystalline products D-mannitol hexanitrate, D,L-tartaric acid dinitrate and m-nitrobenzoic acid were recovered directly in quantitative yield. Good yields of the crystalline although somewhat less pure nitrates of D,L-mandelic acid, β-methyl-D-glucopyranoside and D-sorbitol were obtained in similar nitrations. D-Mannose, D-fructose, dulcitol, sucrose, maltose, lactose, cellobiose, vanillic acid, salicylic acid and vanillin gave poor yields of syrupy nitrated products. A beechwood xylan and holocellulose and lignin of western red cedar, isolated by conventional technics, were nitrated by the gaseous pentoxide method in yields and nitrogen contents comparable to those reported for other nitration methods. The xylan and holocellulose nitrates were incompletely soluble in acetone and the solubility of the nitrated lignin varied with the time of nitration. Optimum conditions were established for the nitration of acetone-extracted western red cedar heartwood. The weight ratio of nitrated wood : wood was closely reproducible and exceeded previously reported values; total nitrogen and ester nitrogen contents of the nitrated wood were reproducible within, the experimental error of the determinations. The nitration reaction was not entirely quantitative since an average of 2.3% methoxyl was lost from the wood and the weight increase calculated from the total nitrogen content was, on the average, 3% lower than the observed value. Successive extraction with anhydrous acetone and methanol applied alternately, dissolved up to thirty-five percent of the nitro-wood and indicated that the nitration-solvent extraction technic should have value as a tool in the study of wood chemistry.

description: Following an initial explosion that might be launched either by magnetic interactions or neutrinos, a rotating magnetar radiating according to the classic dipole formula could power a very luminous supernova. While some 56Ni might be produced in the initial explosion, the peak of the light curve in a Type I supernova would not be directly related to its mass. In fact, the peak luminosity would be most sensitive to the dipole field strength of the magnetar. The tail of the light curve could resemble radioactive decay for some time but, assuming complete trapping of the pulsar emission, would eventually be brighter. Depending on the initial explosion energy, both high and moderate velocities could accompany a very luminous light curve.

description: In 2000, Latanya Sweeny demonstrated that 87% of the US population was uniquely characterized by just three variables: gender, postal code, and birthday. Crucially, because these variables exist in other datasets (e.g., voter registration, health records), these unique combinations can be used to link multiple datasets and reveal potentially sensitive information about individuals. For example, if there is only one woman who lives in 22132 and was born on 1/12/1992, then that person’s identity can be determined on the basis of this information. This “re-identification” risk poses an issue for researchers who seek to release publicly available datasets with quasi-identifying information, i.e., information that can be used to re-identify individuals (e.g., demographic and geographic information). The present preregistration will sample publicly available social-behavioral datasets to provide an initial litmus test of how frequently quasi-identifying information is collected.
Trasporto al plasma per la magnetosfera

La magnetosfera di Giove è un enorme acceleratore di particelle la cui parte interna contiene elettroni ultra-relativistici generati attraverso meccanismi che sono ancora compresi solo parzialmente. Questa regione interna della magnetosfera gioviana viene alimentata da flussi di plasma caldo. Uno studio suScience dimostra che questo trasporto di plasma caldo verso l'interno è continuo e l'immissione di energia è bilanciata dalla rapida perdita per collisioni con la componente più fredda.

Inelastic Dark Matter As An Efficient Fuel For Compact Stars

description: Dark matter in the form of weakly interacting massive particles is predicted to become gravitationally captured and accumulate in stars. While the subsequent annihilations of such particles lead to the injection of energy into stellar cores, elastically scattering dark matter particles do not generally yield enough energy to observably impact stellar phenomenology. Dark matter particles which scatter inelastically with nuclei (such that they reconcile the annual modulation reported by DAMA with the null results of CDMS and other experiments), however, can be captured by and annihilate in compact stars at a much higher rate. As a result, old white dwarf stars residing in high dark matter density environments can be prevented from cooling below several thousand degrees Kelvin. Observations of old, cool white dwarfs in dwarf spheroidal galaxies, or in the inner kiloparsec of the Milky Way, can thus potentially provide a valuable test of the inelastic dark matter hypothesis.

description: We consider an instance of the AdS/CFT duality where the bulk theory contains an open string tachyon, and study the instability from the viewpoint of the boundary field theory. We focus on the specific example of the AdS_5 X S^5 background with two probe D7 branes intersecting at general angles. For generic angles supersymmetry is completely broken and there is an open string tachyon between the branes. The field theory action for this system is obtained by coupling to N =4 super Yang-Mills two N =2 hyper multiplets in the fundamental representation of the SU(N) gauge group, but with different choices of embedding of the two N=2 subalgebras into N=4. On the field theory side we find a one-loop Coleman-Weinberg instability in the effective potential for the fundamental scalars. We identify a mesonic operator as the dual of the open string tachyon. By AdS/CFT, we predict the tachyon mass for small 't Hooft coupling (large bulk curvature) and confirm that it violates the AdS stability bound.

description: The purpose of this study was to examine the attitudes of elementary music students toward singing and choir participation in relation to grade level and gender, classroom singing activities, previous and current out-of-school singing experiences, and degree of singing skill, both self-perceived and assessed. A questionnaire on attitudes toward singing and choir participation was administered to children in grades three through six in Austin, Texas. In addition, individual singing responses of 23% of the subjects were recorded and analyzed to assess singing skill. An analysis of the 542 questionnaires showed that the majority of subjects indicated a positive attitude toward singing, but positive responses at each grade level decreased as grade level increased. Girls and subjects in lower grades showed more positive attitudes than boys and subjects in upper grades. Slightly less than half of all respondents indicated interest in singing in a choir, with significantly more girls than boys showing interest in singing in a choir. Girls and students in the two lower grades responded more positively to items of interest in classroom singing activities and to items on out-of-school singing experiences. Those who liked to sing and those who wanted to sing in a choir also responded more positively. Self-perception of singing skill was more positive at lower grade levels, among girls, and among respondents who liked to sing or wanted to sing in a choir. The only significant relationship between assessed singing skill and other factors in this study was between grade level and melodic accuracy of the better performance of "Jingle Bells," in which fifth- and sixth-graders had higher scores for accuracy than third- and fourth-graders. Relationships between assessed singing skill and grade level, gender, attitude toward singing, and attitude toward choir participation, as well as relationships between self-perception of singing skill and assessed singing skill, were not significant. Results of this study offer the public school music teacher information which may be useful in promoting positive attitude toward singing and choir participation in the classroom and provide the choir director with knowledge helpful for recruitment, rehearsal, and performance purposes
A comparative analysis of standard accretion disks spectra: an application to Ultraluminous X-ray Sources

description: We compare standard models of accretion disks around black holes that include the appropriate zero-torque inner boundary condition and relativistic effects on the emission and propagation of radiation. The comparison is performed adopting the multicolor disk blackbody model (MCD) as reference and looking for the parameter space in which it is in statistical agreement with "more physical" accretion disk models. We find simple 'recipes' that can be used for adjusting the estimates of the physical inner radius of the disk, the black hole mass and the accretion rate inferred using the parameters of the MCD fits. We applied these results to four ULXs for which MCD spectral fits of their X-ray soft spectral components have been published and find that, in three cases (NGC 1313 X-1, X-2 and M 81 X-9), the black hole masses inferred for a standard disk around a Schwarzschild black hole are in the interval ~100-200 solar masses. Only if the black hole is maximally rotating are the masses comparable to the much larger values previously derived in the literature.
