This Holarctic species was reported by Peck and Cook (2002) from Newfoundland and New Brunswick (Fig. 12). The source of the New Brunswick record (from the Charlotte County area) could not be determined (S. Peck, pers. comm.), nor were vouchers specimens found in any collection consulted. Consequently it is removed from the New Brunswick faunal list. Its status in Newfoundland should also be further investigated since there are no records in the province apart from the specimens listed above. Sciodrepoides watsoni has primarily been collected in forested habitats but it is also tolerant of open old fields and grasslands where it is found on carrion and in mammal nests (Peck and Cook 2002).

description: An x-ray free electron laser oscillator (XFELO) has been recently proposed [K. Kim, Y. Shvyd'ko, and S. Reiche, Phys. Rev. Lett. 100, 244802 (2008)]. Angular orientation and position in space of Bragg mirrors of the XFELO optical cavity must be continuously adjusted to compensate instabilities and maximize the output intensity. An angular stability of about 10 nrad (rms) is required [K. Kim and Y. Shvyd'ko Phys. Rev. STAB 12, 030703 (2009)]. To approach this goal, a feedback loop based on a null-detection principle was designed and used for stabilization of a high energy resolution x-ray monochromator ($ΔE/E \simeq 4 \times 10^{-8}$, $E$ = 23.7 keV) and a high heat load monochromator. Angular stability of about 13 nrad (rms) has been demonstrated for x-ray optical elements of the monochromators.

Screening of Asymptomatic Intracranial Arterial Stenosis among High Risk Subjects: A Pilot Study from Egypt
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Background

Stroke ranks as the second leading cause of death and the leading cause of morbidity worldwide. Large intracranial arterial stenosis (ICAS) is a major cause of stroke.

Methods

This study investigated the prevalence and associated vascular risk factors of ICAS in a high-risk population in Qalyeubia Governorate, Egypt. A cross-sectional pilot survey using transcranial Doppler (TCD) was conducted at Toukh Central Hospital and Aghore El-qubra primary healthcare units in the Qalyeubia Governorate from 1 January 2016 until the end of June 2016.

Results

A total of 153 participants were included in this study. The prevalence of asymptomatic ICAS was 13.1%. Among the modifiable risk factors, cardiac diseases, hypertension, diabetes, obesity, dyslipidemia, physical inactivity, and smoking were the strongest independent predictors of ICAS.

Conclusion

This pilot study concluded that the prevalence of asymptomatic ICAS is relatively high in Egypt, and modifiable risk factors were the strongest predisposing factors of ICAS. TCD is an efficient non-invasive modality for the diagnostic evaluation of ICAS.

description: Short gamma-ray bursts (GRBs), typically lasting less than 2 s, are a special class of GRBs of great interest. We report the detection by the AGILE satellite of the short GRB 090510 which shows two clearly distinct emission phases: a prompt phase lasting ~ 200 msec and a second phase lasting tens of seconds. The prompt phase is relatively intense in the 0.3-10 MeV range with a spectrum characterized by a large peak/cutoff energy near 3 MeV, in this phase, no significant high-energy gamma-ray emission is detected. At the end of the prompt phase, intense gamma-ray emission above 30 MeV is detected showing a power-law time decay of the flux of the type t^-1.3 and a broad-band spectrum remarkably different from that of the prompt phase. It extends from sub-MeV to hundreds of MeV energies with a photon index alpha ~ 1.5. GRB 090510 provides the first case of a short GRB with delayed gamma-ray emission. We present the timing and spectral data of GRB 090510 and briefly discuss its remarkable properties within the current models of gamma-ray emission of short GRBs.

Peck (2007) indicated Leptinillus validus as occurring in New Brunswick. Peck (1991) also listed it from Newfoundland, but it is not so indicated in Peck (2007). The above records confirm its presence in insular Newfoundland (Fig. 12). Adults and larvae are ectoparasites of beaver (Castor canadensis Kuhl) in the northern part of their range in North America. They are occasionally, and apparently accidentally, also found on muskrats (Ondatra zibethicus (Linnaeus)) (Peck 2007).

Measurement of binary gaseous diffusion coefficients of polar system
Creators: name: Mian, Aziz Ahmed
Publisher: name: University of British Columbia
Year: 2011

description: This investigation was undertaken primarily for the purpose of collecting reliable experimental data on binary gaseous diffusion coefficients of polar systems. The binary gas pairs investigated were the A - SO₂ , A - HCI , and SO₂ - HCI systems. Diffusion through, a porous solid in a flow apparatus was adopted for the diffusion measurement. The diffusion cell was standardized by making diffusion runs using the N₂ - CO₂ system at 5 different temperatures, room temperature, 70°C, 120°C, 200°C, and 250°C, and using also the N₂ - H₂ system at room temperature. Thermal conductivity cells and chemical methods, alone or in combination, were used for analysis of the gas streams. The results in all these three systems could be represented by straight lines on logarithmic plots of diffusion coefficient against temperatures from 20°C - 250°C. In the first two pas pairs, the experimental coefficients appeared to be 25.3% and 29.2% less at room temperature, and 20.0% and 12.1% less at about 250°C than the respectively predicted values obtained by using the Stockmeyer potential function in the Hirschfelder diffusion equation. The slopes of the lines were 1.988 and 2.42, respectively. It was found that the A - SO₂ system could be represented by a potential function of the Lennard-Jones type, although the molecular force parameters determined from the diffusion data did not agree with those calculated from the pure component values and the usual empriical combining rules. The system A - HCI could not be represented by a function of the Lennard-Jones type. The third system, SO₂ - HCI, was also found to behave more or less the same way as A - HCI system. However, the slope of the line obtained from a Log D vs Log T plot (2.22), was smaller than that of the A - HCI system, although still greater than that predicted by using the Monchick and Mason . (12-6-3) potential function. The magnitudes of the diffusion coefficients within the range of temperatures studied were found to be within 11.0% of the predicted ones. Nevertheless, the system did not conform completely to the Monchick and Mason model. Some qualitative reasons are given for the inadequacies of present potential functions and combining rules for use in predicting binary diffusion coefficients in mixtures containing polar molecules.

description: The SEGUE survey obtained 240,000 moderate resolution (R = 1800) spectra from 3900 - 9000 Angstroms of fainter Milky Way stars (14.0 < g < 20.3) of a wide variety of spectral types, both main sequence and evolved objects, with the goal of studying the kinematics and populations of our Galaxy and its halo. The spectra are clustered in 212 regions spaced over three-quarters of the sky. Radial velocity accuracies for stars are 4 km/s at g < 18, degrading to 15 km/s at g = 20. For stars with S/N > 10 per resolution element, stellar atmospheric parameters are estimated, including metallicity, surface gravity, and effective temperature. SEGUE obtained 3500 square degrees of additional ugriz imaging (primarily at low Galactic latitudes) providing precise multi-color photometry (g,r,i = 2%), (u,z = 3%) and astrometry (0.1 arcsec) for spectroscopic target selection. The stellar spectra, imaging data, and derived parameter catalogs for this survey are publicly available as part of SDSS Data Release 7 (DR7).

description: We present multi-epoch VLBA imaging of the 28SiO v=1 & v=2, J=1-0 maser emission toward the massive YSO Orion Source I. Both SiO transitions were observed simultaneously with an angular resolution of ~0.5 mas (~0.2 AU for d=414 pc). Here we explore the global properties and kinematics of the emission through two 19-epoch animated movies spanning 21 months (2001 March 19 to 2002 December 10). These movies provide the most detailed view to date of the dynamics and temporal evolution of molecular material within ~20-100 AU of a massive (~>8M_sun) YSO. The bulk of the SiO masers surrounding Source I lie in an X-shaped locus; emission in the South/East arms is predominantly blueshifted and in the North and West is predominantly redshifted. In addition, bridges of intermediate-velocity emission connect the red and blue sides of the emission distribution. We have measured proper motions of >1000 maser features and find a combination of radially outward migrations along the four arms and motions tangent to the bridges. We interpret the SiO masers as arising from a wide-angle bipolar wind emanating from a rotating, edge-on disk. The detection of maser features along extended, curved filaments suggests that magnetic fields may play a role in launching and/or shaping the wind. Our observations appear to support a picture in which stars with M ~>8 M_sun form via disk-mediated accretion. However, we cannot rule out that the Source I disk may have been formed or altered following a close encounter. (Abridged).

description: We further develop the constrained mass variable techniques to determine the mass scale of invisible particles pair-produced at hadron colliders. We introduce the constrained mass variable M_3C which provides an event-by-event lower bound and upper bound to the mass scale given the two mass differences between the lightest three new particle states. This variable is most appropriate for short symmetric cascade decays involving two-body decays and on-shell intermediate states which end in standard-model particles and two dark-matter particles. An important feature of the constrained mass variables is that they do not rely simply on the position of the end point but use the additional information contained in events which lie far from the end point. To demonstrate our method we study the supersymmetric model SPS 1a. We select cuts to study events with two Neutralino_2 each of which decays to Neutralino_1, and two opposite-sign same-flavor (OSSF) charged leptons through an intermediate on-shell slepton. We find that with 300 fb^-1 of integrated luminosity the invisible-particle mass can be measured to M=96.4 +/- 2.4 GeV. Combining fits to the shape of the M_3C constrained mass variable distribution with the max m_ll edge fixes the mass differences to +/- 0.2 GeV.

Suzaku Observations of Thermal and Non-Thermal X-Ray Emission from the Middle-Aged Supernova Remnant G156.2+5.7

description: We present results from X-ray analysis of a Galactic middle-aged supernova remnant (SNR) G156.2+5.7 which is bright and largely extended in X-ray wavelengths, showing a clear circular shape (radius about 50'). Using the Suzaku satellite, we observed this SNR in three pointings; partially covering the northwestern rim, the eastern rim, and the central portion of this SNR. In the northwestern rim and the central portion, we confirm that the X-ray spectra consist of soft and hard-tail emission, while in the eastern rim we find no significant hard-tail emission. The soft emission is well fitted by non-equilibrium ionization (NEI) model. In the central portion, a two-component (the interstellar medium and the metal-rich ejecta) NEI model fits the soft emission better than a one-component NEI model from a statistical point of view. The relative abundances in the ejecta component suggest that G156.2+5.7 is a remnant from a core-collapse SN explosion whose progenitor mass is less than 15 M_solar. The origin of the hard-tail emission is highly likely non-thermal synchrotron emission from relativistic electrons. In the northwestern rim, the relativistic electrons seem to be accelerated by a forward shock with a slow velocity of about 500 km/sec.

description: We report on observations of transit events of the transiting planets XO-1b and TrES-1 with a 25 cm telescope of the University Observatory Jena. With the transit timings for XO-1b from all 50 available XO, SuperWASP, Transit Light Curve (TLC)-Project- and Exoplanet Transit Database (ETD)-data, including our own I-band photometry obtained in March 2007, we find that the orbital period is P= (3.941501 +/- 0.000001) d, a slight change by ~3 s compared to the previously published period. We present new ephemeris for this transiting planet. Furthermore, we present new R-band photometry of two transits of TrES-1. With the help of all available transit times from literature this allows us to refine the estimate of the orbital period: P=(3.0300722 +/- 0.0000002) d. Our observations will be useful for future investigations of timing variations caused by additional perturbing planets and/or stellar spots and/or moons.

Weyl's Gauge Invariance: Conformal Geometry, Spinors, Supersymmetry, and Interactions

description: We extend our program, of coupling theories to scale in order to make their Weyl invariance manifest, to include interacting theories, fermions and supersymmetric theories. The results produce mass terms coinciding with the standard ones for universes that are Einstein, but are novel in general backgrounds. They are generalizations of the gravitational couplings of a conformally improved scalar to fields with general scaling and tensor properties. The couplings we find are more general than just trivial ones following from the conformal compensating mechanisms. In particular, in the setting where a scale gauge field (or dilaton) is included, masses correspond to Weyl weights of fields organized in ``tractor'' multiplets. Breitenlohner--Freedman bounds follow directly from reality of these weights. Moreover, massive, massless and partially massless theories are handled in a uniform framework. Also, bona fide Weyl invariant theories (invariant without coupling to scale) can be directly derived in this approach. The results are based on the tractor calculus approach to conformal geometry, in particular we show how to handle fermi fields, supersymmetry and Killing spinors using tractor techniques. Another useful consequence of the construction is that it automatically produces the (anti) de Sitter theories obtained by log-radial reduction of Minkowski theories in one higher dimension. Theories presented in detail include interacting scalars, spinors, Rarita--Schwinger fields, and the interacting Wess--Zumino model.

Un team internazionale di ricercatori ha analizzato in maniera sistematica l’archivio di dati nel database DASCH di Harvard, scoprendo che la variabilità su scala secolare della stella di Tabby, detta anche KIC 8462852, è dovuta a effetti strumentali e non intrinsechi della sorgente. Rimane ancora da scoprire l’origine della bizzarra variabilità mostrata negli ultimi anni dalla stella
Coherent state approach to the cross collisional effects in the population dynamics of a two-mode Bose-Einstein condensate

description: We reanalyze the non-linear population dynamics of a Bose-Einstein Condensate (BEC) in a double well trap considering a semiclassical approach based on a time dependent variational principle applied to coherent states associated to SU(2) group. Employing a two-mode local approximation and hard sphere type interaction, we show in the Schwinger's pseudo-spin language the occurrence of a fixed point bifurcation that originates a separatrix of motion on a sphere. This separatrix corresponds to the borderline between two dynamical regimes of Josephson oscillations and mesoscopic self-trapping. We also consider the effects of interaction between particles in different wells, known as cross collisions. Such terms are usually neglected for traps sufficiently far apart, but recently it has been shown that they contribute to the effective tunneling constant with a factor growing linearly with the particle number. This effect changes considerably the effective tunneling of the system for sufficiently large number of trapped atoms, in perfect accord with experimental data. Finally, we identify analytically the transition parameter associated to the bifurcation in the generalized phase space of the model with cross-collision terms, and show how the dynamical regime depends on the initial conditions of the system and the collisional parameters values.

description: We present the self-dynamics of protein amino acids of hydrated lysozyme powder around the physiological temperature by means of molecular dynamics (MD) simulations. The self-intermediate scattering functions (SISF) of the amino acid residue center-of-mass and of the protein hydrogen atoms display a logarithmic decay over 3 decades of time, from 2 picoseconds to 2 nanoseconds, followed by an exponential alpha-relaxation. This kind of slow dynamics resembles the relaxation scenario within the beta-relaxation time range predicted by the mode coupling theory (MCT) in the vicinity of higher-order singularities. These results suggest a strong analogy between the single-particle dynamics of the protein and the dynamics of colloidal, polymeric and molecular glass-forming liquids.
