The observed bimodality in radio luminosity galaxy clusters is puzzling: cosmic rays (CRs) accelerated by structure formation shocks are expected to indiscriminately produce bright haloes every cluster. We investigate the possibility that CR streaming intracluster medium (ICM) can ‘switch off’ hadronically induced and gamma-ray emission. For self-confined CRs, this depends on source of magnetohydrodynamic wave damping: if only non-linear Landau damping operates, then CRs stream slow Alfvénic...
Cosmic rays (CRs) have recently re-emerged as attractive candidates for mediating feedback in galaxies because of their long cooling timescales. They can energy densities comparable to the thermal gas, but do not suffer catastrophic losses. Recent simulations shown that momentum and deposited by CRs moving with respect ambient medium drive galactic winds. However, are hampered our ignorance details CR transport. Two key limits previously considered model transport a purely diffusive process...
Observations of line ratios in the Milky Way's warm ionized medium suggest that photoionization is not only heating mechanism present. For additional to explain discrepancy, it would have a weaker dependence on gas density than cooling rate, . Reynolds et al. suggested turbulent dissipation or magnetic field reconnection as possible sources. We investigate here viability MHD-wave mediated cosmic ray supplemental source. This rate depends through its linear Alfvén speed, which goes show that,...
Utility functions are used by clients of a service to communicate the value piece work and other QoS aspects such as its timely completion. However, utility on individual items do not capture how important it is complete all or part batch items; for this purpose, higher-level construct required. We propose multi-job aggregate-utility function, show provider that executes jobs rented resources can use drive admission control job scheduling decisions. Using profit-seeking approach policies, we...
Sharing needles/syringes and sexual transmission are widely appreciated as means of HIV among persons who inject drugs (PWIDs). London, Canada, is experiencing an outbreak PWIDs, despite a large needle/syringe distribution program low rates sharing.To determine whether sharing injection drug preparation equipment (IDPE) associated with infection.Between August 2016 June 2017, individuals history use residence in London were recruited to complete comprehensive questionnaire testing.A total...
We investigate the effects of cosmic ray (CR) dynamics on cold, dense clouds embedded in a hot, tenuous galactic halo. If magnetic field does not increase too much inside cloud, local reduction Alfvén speed imposes bottleneck CRs streaming out from star-forming disc. The flattens upstream CR gradient hot gas, implying that multiphase structure could have global CR-driven winds. A large pressure can also develop outward-facing edge cloud. This has two independent effects. push cloud upwards,...
People who inject drugs (PWID) are being treated for infective endocarditis remain at risk of new bloodstream infections (BSIs) due to ongoing intravenous drug use (IVDU).To characterize BSIs in PWID receiving treatment endocarditis, determine the clinical factors associated with their development, and whether setting mortality.This retrospective cohort study was performed 3 tertiary care hospitals London, Ontario, Canada, from April 1, 2007, March 31, 2018. Participants included a...
We investigate a mechanism for accelerating cool (10$^4$ K) clouds in the circumgalactic medium (CGM) with cosmic rays (CRs), possibly explaining some characteristics of observed high velocity (HVCs). Enforcing CRs to stream down their pressure gradient into region slow streaming speed results significant buildup CR which can accelerate CGM. present first two-dimensional magnetohydrodynamic (MHD) simulations such `CR bottlenecks,' expanding on simpler 1D from \cite{wiener17a}. Although much...
The Mindfulness Ambassador Program (MAP) is a group-based, facilitated mindfulness-based intervention (MBI). We sought to determine the effectiveness of MAP on reducing negative psychotic symptoms and enhancing mindfulness skills among persons experiencing early psychosis. conducted pragmatic randomized controlled trial (RCT) at three psychosis (EPI) programs in Ontario, Canada. Participants (N = 59) were randomly assigned receive (n 29) for 1-hour weekly sessions over 3 months, or treatment...
Diffuse, extended radio emission in galaxy clusters, commonly referred to as halos, indicate the presence of high energy cosmic ray (CR) electrons and cluster-wide magnetic fields. We can predict from theory expected surface brightness a halo, given field CR density profiles. Previous studies have shown that nature transport radically effect halo clusters (Wiener et al. 2013). Reasonable levels magnetohydrodynamic (MHD) wave damping lead significant streaming speeds. But careful treatment...
London, Canada, experienced an HIV outbreak among persons who inject drugs despite widespread distribution of harm reduction equipment. Hydromorphone controlled-release (HMC) is the local opioid choice. Injection drug preparation equipment (IDPE; ie, cookers and filters) often shared reused because perception that there residual HMC in IDPE after use. The purpose this study was to investigate mechanisms transmission context.Residual hydromorphone, (controlled-release or immediate-release),...
To describe the provision of care for young people following first diagnosis psychotic disorder. Retrospective cohort study using health administrative data. Ontario. People aged 14 to 35 years with a nonaffective disorder in Ontario between 2005 and 2015 (N=39,449). Models care, defined by psychosis-related service contacts primary physicians psychiatrists during 2 after During 2-year follow-up period, 29% received only 30% psychiatric 32% both (shared care). Among shared group, 72%...
The nature of cosmic rays (CRs) and ray transport in galaxy clusters is probed by a number observations. Radio observations reveal the synchrotron radiation electrons (CRe) spiraling around cluster magnetic fields. $γ$-ray hadronic reactions protons (CRp) with ambient gas nuclei which produce pions. To date, no such cluster-wide signal has been measured, putting an upper limit on density CRp present clusters. But presence CRe implies some source CRp, consequently there must be loss...
Traumatic brain injury (TBI) induces immune dysfunction that can be captured clinically by an increase in the neutrophil-to-lymphocyte ratio (NLR). However, few studies have characterized temporal dynamics of NLR post-TBI and its relationship with hospital-acquired infections (HAI), resource utilization, or outcome. We assessed HAI over first 21 days post-injury adults moderate-to-severe TBI (n = 196) using group-based trajectory (TRAJ), changepoint, mixed-effects multivariable regression...
Abstract Aim Access to a primary care physician in early psychosis facilitates help‐seeking and engagement with psychiatric treatment. We examined access regular people psychosis, compared the general population, explored factors associated access. Methods Using linked health administrative data from Ontario (Canada), we identified aged 14–35 years first diagnosis of nonaffective psychotic disorder ( n = 39 449; 2005–2015). matched cases four randomly selected population controls based on...
Background: Personal narrative plays an important role in the process of recovery from psychotic illnesses. Participatory video is a novel, active intervention that can be used as tool for fostering development among people with psychosis. Aim: To assess feasibility, acceptability and potential clinical utility participatory innovative promoting early Methods: Ten outpatients psychosis programme were recruited to participate 13 biweekly workshops plan, film produce documentary-style videos...
Many health care services are available in both hospital and freestanding settings. Hospital-based providers usually much more expensive than providers. According to Medicare data, costs hospital-based skilled nursing facilities (SNFs) twice those of facilities. While critics charge that this is the result inefficiency, hospitals counter higher caused by treatment sicker patients provision higher-quality care. This paper analyzes research on case-mix differences between hospitalbased SNFs....
