description: In recent years Hagedorn states have been used to explain the physics close to the critical temperature within a hadron gas. Because of their large decay widths these massive resonances lower $η/s$ to near the AdS/CFT limit within the hadron gas phase. A comparison of the Hagedorn model to recent lattice results is made and it is found that for both Tc =176 MeV and Tc=196 MeV, the hadrons can reach chemical equilibrium almost immediately, well before the chemical freeze-out temperatures found in thermal fits for a hadron gas without Hagedorn states. In this paper we also observe the effects of Hagedorn States on the $K^+/π^+$ horn seen at AGS, SPS, and RHIC.

IRAS 18113-2503: the water fountain with the fastest jet?

description: We present Expanded Very Large Array (EVLA) water maser observations at 22 GHz toward the source IRAS 18113-2503. Maser components span over a very high velocity range of ~500 km/s, the second largest found in a Galactic maser, only surpassed by the high-mass star forming region W49N. Maser components are grouped into a blue and a redshifted cluster, separated by 0.12". Further mid-IR and radio data suggest that IRAS 18113-2503 is a post-AGB star, thus a new bona fide member of the rare class of "water fountains". It is the evolved object with the largest total velocity spread in its water masers, and with the highest velocity dispersion within its red- and blue-shifted lobes (~170 km/s). The large total velocity range of emission probably indicates that IRAS 18113-2503 has the fastest jet among the known water fountain stars. On the other hand, the remarkably high velocity dispersion within each lobe may be interpreted in terms of shocks produced by an episode of mass ejection whose velocity increased up to very high values or, alternatively, by projection effects in a jet with a large opening angle and/or precessing motions.

description: In this work we use a series of open clusters and associations observed by the Gaia-ESO Survey (GES) to study the use of lithium abundances (Li I spectral line at 6708 Å) as an age indicator for pre- and main-sequence FGKM late-type stars. Previous studies of open clusters have shown that lithium depletion is not only strongly age dependent, but also shows a complex pattern with several other parameters, such as rotation, chromospheric activity and metallicity. Using the available data from both GES iDR6 and Gaia EDR3, we performed a thorough membership analysis and obtained lists of candidate members for 41 open clusters, ranging in age from 1-3 Myr to 5 Gyr. We then conducted a comparative study that allowed us to quantify the observable lithium dispersion in each cluster and study influence of rotation, activity and metallicity in the lithium dispersion of the selected candidates. All this allows us to calibrate a Li-age relation and create empirical lithium envelopes for several clusters in our sample.

description: On the one hand, inflation is an extremely convincing scenario: it solves most cosmological paradoxes and generates fluctuations that became the seeds for the growth of structures. It, however, suffers from a "naturalness" problem: generating initial conditions for inflation is far from easy. On the other hand, loop quantum cosmology is very successful: it solves the Big Bang singularity through a non-perturbative and background-independent quantization of general relativity. It, however, suffers from a key drawback: it is extremely difficult to test. Recent results can let us hope that inflation and LQC could mutually cure those pathologies: LQC seems to naturally generate inflation and inflation could allow us to test LQC.

New theorem of classical electromagnetism: equilibrium magnetic field and current density are zero inside ideal conductors

description: We prove a theorem on the magnetic energy minimum in a system of perfect, or ideal, conductors. It is analogous to Thomson's theorem on the equilibrium electric field and charge distribution in a system of conductors. We first prove Thomson's theorem using a variational principle. Our new theorem is then derived by similar methods. We find that magnetic energy is minimized when the current distribution is a surface current density with zero interior magnetic field; perfect conductors are perfectly diamagnetic. The results agree with currents in superconductors being confined near the surface. The theorem implies a generalized force that expels current and magnetic field from the interior of a conductor that loses its resistivity. Examples of solutions that obey the theorem are presented.

subject: FOS: Physical sciences

description: Based on numerical solutions of the time-dependent Schrödinger equation for either one or two active electrons, we propose a method for observing instantaneous level shifts in an oscillating strong infrared (IR) field in time, using a single tunable attosecond pulse to probe excited states of the perturbed atom. The ionization probability in the combined fields depends on both, the frequency of the attosecond pulse and the time delay between both pulses, since the IR field shifts excited energy levels into and out of resonance with the attosecond probe pulse. We show that this method (i) allows the detection of instantaneous atomic energy gaps with sub-laser-cycle time resolution and (ii) can be applied as an ultrafast gate for more complex processes such as non-sequential double-ionization.

description: A diffeomorphism of pseudo-Riemannian manifolds is called sectional curvature preserving if it preserves the sectional curvature of all the nondegenerate 2-planes. We consider a similar condition for degenerate 2-planes and we prove that the diffeomorphism is conformal (when the condition is fulfilled for weakly degenerate planes) or an isometry (when the condition is fulfilled for strongly degenerate 2-planes).

description: Given the closeness of the two open clusters Collinder 135 and UBC 7 on the sky, we investigated the possibility that the two clusters are physically related. We recovered the present-day stellar membership in these open clusters (300 pc from the Sun) to constrain their kinematic parameters, ages, and masses and to restore their primordial phase space configuration. We investigate the system of these two clusters and possibly coeval stars in 6D space with Gaia EDR3. The actual separation of the cluster centers is equal to 22 pc. Their age is identical, between 40 and 50 Myr, and space motions similar. We conclude that the two clusters Cr 135 and UBC 7 might have formed a physical pair based on the observational evidence as well as numerical simulations. The orbital integration of cluster trajectories backward in time shows that the clusters were much closer in the past if their current line-of-sight velocities are very similar and the total mass is more than seven times larger than the mass of the most reliable members. The census of stars related to this system in the broad surrounding area reveals an extended asymmetric halo of stars related to the system, of total mass comparative to the mass of stars in clusters. This supports the hypothesis of strong cluster mass loss by violent relaxation in the first 20 Myr.

description: The Canis Major star-forming field is dominated by the extended Seagull Nebula and contains a number of HI shells, associated with both the Local or Perseus arms. The positional coincidence of the bright O and B stars in this direction and one of the major shells in the region, GSH 224-01+24, may be indicative of an interaction with the shell’s material. We use a sample of 260 bright O-B9 type field stars that is about 90% complete up to 12 magnitude and involve uvbyβ photometry and the Gaia EDR3 data to study the distribution of the bright young stars in this region.
Emergency health care providers’ perspectives on providing care to racialized immigrant women experiencing intimate partner violence
Creators: name: Mattu, Beljinder
Publisher: name: University of British Columbia
Year: 2022

description: Background: Intimate partner violence (IPV) can impact all Canadian women regardless of socioeconomic status, race, age, or ethnicity. In Canada, prevalence rates are estimated to be 6% to 8%, but many experts argue that rates may be even higher. As well, racialized immigrant women experiencing IPV are likely to face interpersonal and structural barriers to care when accessing services and engaging with health care providers (HCPs). To date, research focusing on emergency department (ED) health care professionals’ perspectives and experiences caring for racialized immigrant women experiencing IPV has been limited. Purpose: The purpose of this study was to explore and better understand ED HCPs’ perspectives on providing care for racialized immigrant women experiencing IPV. The research was conducted at a large urban hospital located in the Lower Mainland of British Columbia (BC). A significant percentage of the population that the hospital serves are foreign-born immigrants originating from India and are of Punjabi-Sikh descent. Given this demographic, it is highly likely that HCPs have cared for Punjabi-Sikh women in the ED. Method: This study used a qualitative descriptive research design. Cultural safety was the theoretical framework used in this study. A convenience sampling approach was used to recruit 5 HCPs. The HCPs consisted of ED nurses, forensic nurses, and social workers who were primarily employed in the ED. This study used individual interviews and a thematic approach to analysis. Findings: The provision of adequate care to racialized immigrant women with IPV issues in the ED was hindered by several issues including the absence of resources, HCPs’ biases, lack of privacy in the ED, long waiting hours, and a lack of time to deal with IPV cases. The study also suggested that ED nurses had to identify IPV cases amongst racialized immigrant women. Implications: Future research should focus on the availability of information and training of ED HCPs to improve care provision for racialized immigrant women. This study also proposed that evidence-based research could help with understanding the unique IPV problems faced by racialized immigrant women, and help to facilitate the provision of efficient care in the ED.

description: Following Gott et al. (2001), we use Huchra's final compilation of 553 measurements of the Hubble constant ($H_0$) to determine median statistical constraints on $H_0$. We find $H_0=68 \pm 5.5$ (or $\pm 1$) $\kmsmpc$, where the errors are the 95% statistical and systematic (or statistical) errors. With about two-third more measurements, these results are close to what Gott et al. found a decade ago, with smaller statistical errors and similar systematic errors.

description: There is a dearth of research in the UK eliciting the voices of autistic gender-diverse young people exploring their lived experiences, including their educational experiences. This research explored the experiences of autistic young people in the UK who are gender-diverse (participants were transgender, non-binary or gender questioning), related to gender identity and autism, particularly looking at their experiences of education. Semi-structured interviews were conducted with six autistic gender-diverse young people (aged 16 to 26 years old), which were analysed using Interpretative Phenomenological Analysis (IPA). This qualitative approach examines how individuals make sense of their life experiences. Five superordinate themes emerged from the analysis: My identity – understanding me, acceptance & rejection; Emotional & mental health challenges; Emotional, social, & physical transition; School (& College) stressors; and Supportive solutions at school. Findings are discussed in relation to psychological research and theory, several areas for future research are identified. Findings are relevant to professionals, so that the needs of these young people are better understood, particularly those that work in education including school staff and Educational Psychologists (EPs). EPs are well positioned to offer children and young people (CYP) support at an individual and systemic level, including sharing their knowledge with school staff to help ensure gender-diverse autistic young people’s needs are better met.

description: Pico presentation EGU 2023 The unprecedented precision of the altimetry satellite ICESat-2 and the increasing availability of high-resolution elevation datasets open new opportunities to measure snow depth in the mountains, a critical variable for ecosystems and water resources monitoring. We retrieved snow depth over the upper Tuolumne basin (California, USA) for three years by differencing ICESat-2 ATL06 snow-on elevations and various snow-off elevation sources, including ATL06 and external digital elevation models. The snow presence of each ATL06 segment (i.e. point measurements regularly spaced every 20 m) can be determined from the number of photons returned by the ground surface. Snow depth derived from ATL06 data only (snow-on and snow-off) provided a poor temporal and spatial coverage, limiting its utility. However, using airborne lidar or satellite photogrammetry elevation models as snow-off elevation source yielded an accuracy of ~0.2 m (bias), a precision of ~0.5 m for low slopes and ~1.2 m for steeper areas, compared to eight reference airborne lidar snow depth maps. The snow depth derived from ICESat-2 ATL06 will help address the challenge of measuring the snow depth in unmonitored mountainous areas.

A displaced vertex trigger selects long-lived D0 candidates in the μ+ μ-, π+π-, and K-π+ decay modes. We use the Cabibbo-favored D0 \to K-π+ channel to optimize the selection criteria in an unbiased manner, and the kinematically similar D0 \toπ+ π- channel for normalization. We set an upper limit on the branching fraction (D0 --> μ+ μ-) < 2.1 E-7 (3.0 E-7) at the 90% (95%) confidence level.

description: In recent years, there has been an increased emphasis on reducing the carbon emissions from electricity consumption. Many organizations have set ambitious targets to reduce the carbon footprint of their operations as a part of their sustainability goals. The carbon footprint of any consumer of electricity is computed as the product of the total energy consumption and the carbon intensity of electricity. Third-party carbon information services provide information on carbon intensity across regions that consumers can leverage to modulate their energy consumption patterns to reduce their overall carbon footprint. In addition, to accelerate their decarbonization process, large electricity consumers increasingly acquire power purchase agreements (PPAs) from renewable power plants to obtain renewable energy credits that offset their "brown" energy consumption. There are primarily two methods for attributing carbon-free energy, or renewable energy credits, to electricity consumers: location-based and market-based. These two methods yield significantly different carbon intensity values for various consumers. As there is a lack of consensus which method to use for carbon-free attribution, a concurrent application of both approaches is observed in practice. In this paper, we show that such concurrent applications can cause discrepancies in the carbon savings reported by carbon optimization techniques. Our analysis across three state-of-the-art carbon optimization techniques shows possible overestimation of up to 55.1% in the carbon reductions reported by the consumers and even increased emissions for consumers in some cases. We also find that carbon optimization techniques make different decisions under the market-based method and location-based method, and the market-based method can yield up to 28.2% less carbon savings than those claimed by the location-based method for consumers without PPAs.

description: Reliable fundamental parameters of open clusters such as distance, age and extinction are key to our understanding of the Galactic structure and stellar evolution. In this work we present astrometric and fundamental parameters for thousands open clusters investigated using Gaia data, based on memberships determined using a combination of methods applied to Gaia astrometric data as well as obtained from other authors in the literature. Mean radial velocities were also determined for 47% of the clusters, many of which had no previous published values. The distances and ages determined through our improved isochrone fitting, now takes into account the interstellar extinction using an updated extinction polynomial for the Gaia photometric band-passes. A Galactic abundance gradient has also been used as a prior for metallicity along with an extinction prior based on the 3D structure of the Local Galaxy. The updated procedure was validated with a sample of clusters with high quality [Fe/H] determinations. Based on this catalog we present a critical review of the literature showing that our cluster parameter determinations represent a substantial improvement in fundamental parameter estimates. This has allowed us, for example, to re-estimate the rotation velocity of the arms of the Galaxy (28.5 +/- 1.0 km/s/kpc) from the clusters birthplaces, implying that the corotation radius is close to the solar Galactic orbit (R_c/R_0 = 1.01 +/- 0.08).

Lessons learnt: poultry agroforestry in the UK

description: In a report produced during 2017 as part of the EU FP7 project Agforward, Sally Westaway with colleagues describes the results of the experimental work.  The research focused on performance of three pasture mixtures sown under trees in a silvopoultry system. Establishing a sward under the trees is possible but the challenge is to maintain the sward in the presence of chickens. The three tested seed mixtures (a standard sward, a grass-only sward, and a diverse sward) showed a similar coverage of sown plants in the first six weeks after seeding. One of the recommendations from the research is that sufficient time is provided to allow the reseeded pasture to establish before the re-introduction of the hens. Following the re-introduction of the hens, the sown sward mixtures only survived only in the block with lower chicken pressure, measured by distance from the hen house. Hence designs that prevent excessive pressure from the flock appear to be necessary to help maintain the pasture sward.
Development of novel grain refiners for AZ91D magnesium alloys and their effect on hot tearing

description: Wider implementation of ultralight magnesium (Mg) alloys in engineering applications can be achieved if the mechanical properties of mass produced as-cast alloys can be further enhanced. Grain refinement of aluminum alloys has supported such initiatives over the past few decades; however, a potent and cost-effective grain refiner for common aluminum containing Mg alloys remains elusive. Further, the effect of grain refinement on common casting defects, such as hot tearing, in Mg alloys remains unclear. In this work, several novel grain refiners were produced via the powder metallurgical process known as spark plasma sintering (SPS). The novel grain refiners were used to treat AZ91D Mg alloy and a grain size reduction of ~75 - 85% was achieved, along with improved dispersion of secondary phases and modified eutectics. Such microstructure modifications during solidification resulted in the elimination of hot tearing in castings where hot tearing was typically observed. The SPS’ed refiners were also observed to outperform a common commercially available grain refiner. Many advanced analysis techniques that were implemented in this research provided further understanding of the mechanism behind the effectiveness of the SPS’ed grain refiners. Additionally, the casting experiments were completed using a unique force contraction mold, providing quantitative data during solidification. Furthermore, the results of microstructure evolution, solidification kinetics and forces, as well as in-situ solidification analysis via neutron diffraction, was related to the grain refinement and hot tearing of AZ91D Mg alloy.
