Abstract
Choice of housing has become an important political and therapeutic goal for psychiatric rehabilitation. We conducted a systematic review and meta-analysis of proportions of studies on preference for independent housing. A subgroup analysis compared studies with homeless and non-homeless consumers. The meta-analysis included 8 studies with 3134 consumers. The overall proportion of consumers who had expressed a preference for living independently was 0.84. There were only marginal differences between studies with homeless and non-homeless consumers. In a given service planning area, the rate of independent housing settings should exceed the rate of more institutionalized settings by a wide margin.

Abstract
Self-modulation of an electron beam in a plasma has been observed. The propagation of a long (several plasma wavelengths) electron bunch in an overdense plasma resulted in the production of multiple bunches via the self-modulation instability. Using a combination of a radio-frequency deflector and a dipole spectrometer, the time and energy structure of the self-modulated beam was measured. The longitudinal phase space measurement showed the modulation of a long electron bunch into three bunches with an approximately 200 keV/c amplitude momentum modulation. Demonstrating this effect is a breakthrough for proton-driven plasma accelerator schemes aiming to utilize the same physical effect.

Abstract
Tashiro (1922) showed that the isolated frog nerve liberates ammonia on stimulation, and Richter and Dawson (1948) have recently found that ammonia is liberated on stimulation by the brain. Ammonia is very toxic to the brain, on which it has an irritant action; but the brain may be protected to some extent by the enzyme system described by Krebs (1935), which can detoxicate ammonia by combination with glutamic acid to form glutamine. Sapirstein (1943) obtained evidence that this system is active in vivo by showing that glutamic acid increases the resistance of animals to convulsions produced by injecting ammonium chloride. The toxic action of ammonia on the brain is also of interest in connection with the view that it may be concerned in certain forms of epilepsy (Harris, 1945). This view is supported by the observations of Price, Waelsch and Putnam (1943) on the inhibitory action of glutamic acid on petit mal attacks.

Abstract
The Korea-United States Air Quality Study (KORUS-AQ) conducted during May-June 2016 offered the first opportunity to evaluate direct-sun observations of formaldehyde (HCHO) total column densities with improved Pandora spectrometer instruments. The measurements highlighted in this work were conducted both in the Seoul megacity area at the Olympic Park site (37.5232° N, 27.1260° E; 26 ma.s.l.) and at a nearby rural site downwind of the city at the Mount Taehwa research forest site (37.3123° N, 127.3106° E; 160ma.s.l.). Evaluation of these measurements was made possible by concurrent ground-based in situ observations of HCHO at both sites as well as overflight by the NASA DC-8 research aircraft. The flights provided in situ measurements of HCHO to characterize its vertical distribution in the lower troposphere (0-5km). Diurnal variation in HCHO total column densities followed the same pattern at both sites, with the minimum daily values typically observed between 6:00 and 7:00 local time, gradually increasing to a maximum between 13:00 and 17:00 before decreasing into the evening. Pandora vertical column densities were compared with those derived from the DC-8 HCHO in situ measured profiles augmented with in situ surface concentrations below the lowest altitude of the DC-8 in proximity to the ground sites. A comparison between 49 column densities measured by Pandora vs. aircraft-integrated in situ data showed that Pandora values were larger by 16% with a constant offset of 0.22DU (Dobson units; R 2 = 0.68). Pandora HCHO columns were also compared with columns calculated from the surface in situ measurements over Olympic Park by assuming a well-mixed lower atmosphere up to a ceilometer-measured mixed-layer height (MLH) and various assumptions about the small residual HCHO amounts in the free troposphere up to the tropopause. The best comparison (slope = 1.03±0.03; intercept = 0.29±0.02DU; and R 2 = 0.78±0.02) was achieved assuming equal mixing within ceilometer-measured MLH combined with an exponential profile shape. These results suggest that diurnal changes in HCHO surface concentrations can be reasonably estimated from the Pandora total column and information on the mixed-layer height. More work is needed to understand the bias in the intercept and the slope relative to columns derived from the in situ aircraft and surface measurements.

Abstract
In mental health nursing, recovery-orientation is regarded as a best practice approach for patient care. To assess the effect of an intervention utilising a recovery-oriented approach in acute practice, a controlled pilot trial was conducted. On intervention wards, mental health nurses received special training. Recovery Self-Assessment Scale was used to assess the effects of the training. No statistically significant effects were found, between the experimental conditions. Reasons for this result may be methodological, practical or due an intervention that was not powerful enough. Recovery-oriented intervention studies in mental health nursing should be conducted with caution.

Abstract
OBJECTIVE To systematically explore the outcomes of Independent Housing and Support (IHS) for people with severe mental disorders when compared to other residential settings. METHOD Systematic review of Randomised and Non-Randomised Controlled Trials of publications that analyse the outcomes of living in independent settings versus institutionalised accommodation. Risk of bias assessment was adapted from the Cochrane Collaboration's ACROBAT-Tool. The analysis was conducted separately for publications with homeless and non-homeless people. RESULTS Twenty-four publications from studies with homeless people and eight publications from studies with non-homeless people were included. Risk of bias was much lower in studies with the homeless. No RCT was found in the sample of publications with the non-homeless. Overall, results from Independent Housing and Support-settings are not inferior to results from institutionalised settings. CONCLUSION The results indicate that Independent Housing and Support-settings provide at least similar outcomes than residential care. We propose that clients' preferences should determine the choice of housing setting.

Abstract
We report a neutron-scattering investigation on the structure and dynamics of a single-component nanocomposite based on SiO_{2} particles that were grafted with polyisoprene chains at the entanglement limit. By skillful labeling, we access both the monomer density in the corona as well as the conformation of the grafted chains. While the corona profile follows a r^{-1} power law, the conformation of a grafted chain is identical to that of a chain in a reference melt, implying a high mutual penetration of the coronas from different particles. The brush crowding leads to topological confinement of the chain dynamics: (i) At local scales, the segmental dynamics is unchanged compared to the reference melt, while (ii) at the scale of the chain, the dynamics appears to be slowed down; (iii) by performing a mode analysis in terms of end-fixed Rouse chains, the slower dynamics is tracked to topological confinement within the cone spanned by the adjacent grafts; (iv) by adding 50% matrix chains, the topological confinement sensed by the grafted chain is lifted partially and the apparent chain motion is accelerated. We observe a crossover from pure Rouse motion at short times to topological confined motion beyond the time when the segmental mean squared displacement has reached the distance to the next graft.

Abstract
BACKGROUND Current European Guidelines suggest the use of cardiovascular risk categories and also recommend using high-intensity statins for patients with acute coronary syndromes (ACS). OBJECTIVE We examined the risk of ACS patients prior to the event, as well as the overall use and intensity of statins. METHODS We enrolled 687 ACS patients (mean age 63 years, 78% males). Low-density lipoprotein cholesterol (LDL-C) levels upon admission were used to assess attainment of LDL-C targets. Patients were categorized as very high, high, moderate and low risk based on their prior to admission cardiovascular (CV) risk. We examined statin use and dosage intensity among patients discharged from the hospital. Patients were followed for a median period of 189 days. RESULTS The majority of the patients (n=371, 54%) were at very high CV risk prior to admission, while 101 patients were at high risk (15%), 147 (21%) moderate risk and 68 (10%) low risk. Interestingly, LDL-C target attainment decreased as the risk increased (p<0.001). The majority (96%) of patients received statins at discharge; however, most of them (60.4%) received low/moderate intensity statins and just 35.9% received the suggested by the Guidelines high-intensity dose of statins. At follow-up, the rate of patients at high-intensity dose of statins remained similar (34.8%); 6% received no statins at all at follow-up. CONCLUSION According to our study, the majority of ACS patients are already at high risk prior to their admission. Further, LDL-C targets are underachieved prior to the event and high-intensity statins are underutilized in ACS patients at, and post-discharge.
