Clinical Sociology and Community Interventions

open access: yesClinical Sociology Review
At least 235,000 people experience homelessness in Canada each year, with over 35,000 experiencing homelessness on any given night (Gaetz et al. 2013a). For many, maintaining housing is challenging due to the absence of essential life skills. This paper

Enhancement of Arctic surface ozone during the 2020–2021 winter associated with the sudden stratospheric warming

open access: yesEnvironmental Research Letters, 2023
Surface ozone is an important pollutant causing damage to human health and ecosystems. Here, we find that the Arctic surface ozone during the 2020–2021 winter was evidently enhanced after the sudden stratospheric warming (SSW) onset based on reanalysis ...

Skip-Sliding Window Codes

open access: yes, 2018
Constrained coding is used widely in digital communication and storage systems. In this paper, we study a generalized sliding window constraint called the skip-sliding window.

Influences of Sudden Stratospheric Warming Events on Tropopause Based on GNSS Radio Occultation Data

open access: yesAtmosphere, 2023
Sudden Stratospheric Warming (SSW) events have a strong impact on the tropospheric weather and climate. Past researchers have carried out extensive studies investigating the theories of interactions between the stratosphere and the troposphere.

Predicting sudden stratospheric warming 2018 and its climate impacts with a multi‐model ensemble [PDF]

open access: yes, 2018
Sudden stratospheric warmings (SSWs) are significant source of enhanced subseasonal predictability, but whether this source is untapped in operational models remains an open question.

Variability of MLT winds and waves over mid-latitude during the 2000/2001 and 2009/2010 winter stratospheric sudden warming [PDF]

open access: yesAnnales Geophysicae, 2012
The mesosphere and lower thermosphere (MLT) wind structure over Wuhan (30° N, 114° E) in 2000/2001 winter and over Langfang (39.4° N, 116.6° E) in 2009/2010 winter are examined to reveal the effects of stratospheric sudden warming (SSW) in mid-low ...

Comparison of Antarctic total ozone behavior in pre-SSW, SSW, and post-SSW years

open access: yesУкраїнський антарктичний журнал
Sudden stratospheric warmings (SSWs) are dramatic events characterized by sudden and sharp changes in the distribution of polar stratospheric temperatures, zonal winds, total ozone column, and other atmospheric parameters.

The formation and ordering of local magnetic moments in Fe-Al alloys

open access: yes, 2007
With density functional theory, studied are the local magnetic moments in Fe-Al alloys depending on concentration and Fe nearest environment. At zero temperature, the system can be in different states: ferromagnetic, antiferromagnetic and spin-spiral ...

Correcting the extended-source calibration for the Herschel-SPIRE Fourier-transform spectrometer [PDF]

open access: yes, 2017
We describe an update to the Herschel-Spectral and Photometric Imaging Receiver (SPIRE) Fourier-transform spectrometer (FTS) calibration for extended sources, which incorporates a correction for the frequency-dependent far-field feedhorn efficiency, ηff.

Evidence That Microorganisms at the Animal-Water Interface Drive Sea Star Wasting Disease

open access: yesFrontiers in Microbiology, 2021
Sea star wasting (SSW) disease describes a condition affecting asteroids that resulted in significant Northeastern Pacific population decline following a mass mortality event in 2013. The etiology of SSW is unresolved.
