Abstract
In this work, we use measurements of galaxy stellar mass and two-point angular correlation functions to constrain the stellar-to-halo mass ratios (SHMRs) of passive and star-forming galaxies at z ∼ 2–3, as identified in the Spitzer Matching Survey of the UltraVISTA ultra-deep Stripes. We adopt a sophisticated halo modeling approach to statistically divide our two populations into central and satellite galaxies. For central galaxies, we find that the normalization of the SHMR is greater for our passive population. Through the modeling of Λ cold dark matter halo mass accretion histories, we show that this can only arise if the conversion of baryons into stars was more efficient at higher redshifts and additionally that passive galaxies can be plausibly explained as residing in halos with the highest formation redshifts (i.e., those with the lowest accretion rates) at a given halo mass. At a fixed stellar mass, satellite galaxies occupy host halos with a greater mass than central galaxies, and we find further that the fraction of passive galaxies that are satellites is higher than for the combined population. This, and our derived satellite quenching timescales, combined with earlier estimates from the literature, support dynamical/environmental mechanisms as the dominant process for satellite quenching at z ≲ 3.

Abstract
We show that there is a new class of gas tails—slingshot tails—that form as a subhalo (i.e., a subcluster or early-type cluster galaxy) moves away from the cluster center toward the apocenter of its orbit. These tails can point perpendicular or even opposite to the subhalo direction of motion, not tracing the recent orbital path. Thus, the observed tail direction can be misleading, and we caution against naive conclusions regarding the subhalo’s direction of motion based on the tail direction. A head-tail morphology of a galaxy’s or subcluster’s gaseous atmosphere is usually attributed to ram pressure stripping, and the widely applied conclusion is that gas stripped tail traces the most recent orbit. However, during the slingshot tail stage, the subhalo is not being ram pressure stripped (RPS) and the tail is shaped by tidal forces more than just the ram pressure. Thus, applying a classic RPS scenario to a slingshot tail leads not only to an incorrect conclusion regarding the direction of motion but also to incorrect conclusions regarding the subhalo velocity, expected locations of shear flows, instabilities, and mixing. We describe the genesis and morphology of slingshot tails using data from binary cluster merger simulations and discuss their observable features and how to distinguish them from classic RPS tails. We identify three examples from the literature that are not RPS tails but slingshot tails and discuss other potential candidates.
A Fast Poisson Solver of Second-order Accuracy for Isolated Systems in Three-dimensional Cartesian and Cylindrical Coordinates
Authors: Moon Sanghyuk , Kim Woong-Tae , Ostriker Eve C. 
Published: March 2019

Abstract
We present an accurate and efficient method to calculate the gravitational potential of an isolated system in 3D Cartesian and cylindrical coordinates subject to vacuum (open) boundary conditions. Our method consists of two parts: an interior solver and a boundary solver. The interior solver adopts an eigenfunction expansion method together with a tridiagonal matrix solver to solve the Poisson equation subject to the zero boundary condition. The boundary solver employs James’s method to calculate the boundary potential due to the screening charges required to keep the zero boundary condition for the interior solver. A full computation of gravitational potential requires running the interior solver twice and the boundary solver once. We develop a method to compute the discrete Green’s function in cylindrical coordinates, which is an integral part of the James algorithm to maintain second-order accuracy. We implement our method in the Athena++ magnetohydrodynamics code and perform various tests to check that our solver is second-order accurate and exhibits good parallel performance.

Introduction: Chronic obstructive pulmonary disease (COPD) is one of the most common pathologies of the respiratory system. This disease ranks third in the group of the main causes of death in the world. The effective treatment of COPD has been developed by today. However, a significant part of physicians has an insufficient amount of education in this matter.
Materials and methods: The article represents the results of anonymous prospective survey within the ASCO project (full title – “Assessment of Senior Medical Students in the Field of COPD”), aimed at assessing the basic knowledge in the COPD treatment. The survey involved 321 physicians and 221 senior medical students from ten cities of Russia and Ukraine.
Results and discussion: According to the survey, the following levels of correct answers were given by the doctors and students: possible fixed combinations of β2-agonist – 33.9% and 24.5%; the optimal delivery device for a patient – 50.8% and 41.8; the correct drugs for COPD initial therapy with a high risk of exacerbations – 31.7% and 15.3%, and with a low risk – 54.9% and 25.9%, respectively. The correct drugs for COPD aggravation were selected by 43.3% of doctors and 34.5% of students; the right empirical treatment of COPD infectious exacerbation – by 72.4% and 40%, and the correct reserve drugs – by 63.9% and 36.2%, respectively.
Conclusion: The survey showed that the respondents had medium level of knowledge in COPD treatment. Hence, curricula need to be adjusted in medical universities, and additional educational activities are required for medical practitioners in order to improve the quality of their knowledge in this field.

Abstract
Observed degradation of aquatic systems at Big Stone National Wildlife Refuge, located in west-central Minnesota, have been associated with sediment-laden inflows from riverine systems. To support management, a study was conducted during 2013–2014 with overall goals of characterizing the aquatic invertebrate and vegetation communities of the Big Stone National Wildlife Refuge and exploring relations between these communities and various water-quality parameters. Sample sites were located along an observed vegetation gradient and assigned to three predetermined habitat zones for comparison purposes: upstream, transition, and downstream. Of the 12 species of aquatic vegetation that were identified, invasive narrowleaf cattail Typha angustifolia dominated the upstream zone (observed at &gt;90% of sample locations), coontail Ceratophyllum demersum and narrowleaf cattail were most common in the transition zone (collected or observed at 100 and 83% of sample locations, respectively), and coontail and narrowleaf pondweed Potamogeton strictifolius were most common in the downstream zone (collected at 100 and 64% of sample locations, respectively). Measured values for the water-quality parameters varied among dates, reflecting the continually fluctuating nature of riverine systems. Based on general observations across sample dates, turbidity and dissolved oxygen concentrations were greatest in the upstream zone sample sites, while oxidation-reduction potential was greatest in the downstream zone sites. There were 115 unique aquatic invertebrate taxa identified to varying levels of taxonomic resolution. Results suggested that there were overall differences in invertebrate biomass among the sample dates, but that there were no strong trends among the sample zones. Aquatic invertebrates and vegetation communities, along with the water-quality parameters, varied temporally and showed irregular relations among the sample zones. These general observations emphasize the importance of temporally and spatially intensive sampling to account for natural variation. Moreover, short- and long-term streamflow and water-level information obtained for this study demonstrated substantial variability that must be considered when conducting biotic inventories and monitoring water quality, as well as when using such data to assess management options. Periodic monitoring of wetlands and associated streamflows, along with sediment loads and water quality of inflows, should allow Big Stone National Wildlife Refuge staff to identify habitat degradation and potential contributing factors, and to develop strategies to achieve specific management objectives and goals.

Published: March 2019

ContextAthletic training programs are required to incorporate the development of many foundational skills and behaviors into the curriculum. Athletic training students must develop soft skills such as effective communication, exhibiting empathy, dependability, and integrity, which are all associated with quality athletic trainers.ObjectiveTo describe a novel approach to promoting the awareness of values and development of the characteristics and soft skills associated with being a successful student and health care professional for students before they enter their clinical experiences.BackgroundGraduate and undergraduate programs typically offer an introductory course to students before their first clinical assignment. The main emphasis of introductory courses is often on learning foundational knowledge and technical skills. However, early adoption of professional values and development of soft skills may benefit students as they start their clinical experiences.DescriptionA course was designed using 11 main themes to guide student learning in values and behaviors important to academics and a career in health care. This article describes how the 11 themes were selected and developed, how the course was delivered, and how various pedagogical strategies were incorporated.Clinical Advantage(s)Development of soft skills may benefit athletic training students as they enter the professional phase of an athletic training program.Conclusion(s)As athletic training education shifts to the master's level, fostering soft skills and necessary preclinical skills for students from varied backgrounds is becoming ever more important so students are all equitably prepared for their first clinical experiences.
The effect of a serious game on empathy and prejudice of psychology students towards persons with disabilities
Authors: Olivier Linda , Sterkenburg Paula , Van Rensburg Esmé 
Published: March 2019

Background: Much has been done regarding the promotion of equality in rights in terms of legislation, but persons with disabilities remain marginalised in society. Negative attitudes and prejudice contribute towards numerous challenges for persons with disabilities.Objectives: This study investigated the level of empathy and prejudice of students towards persons with disabilities, and the effect of the use of a serious game to enhance empathy and reduce prejudice.Method: A randomised controlled experiment with pre-test, post-test and follow-up test was used. Availability sample (N = 83) of psychology university students (22% males; 78% females) was divided into an experimental group that played the serious game The World of Empa and two control groups. The first control group received texts on case studies and information on reacting in a sensitive and responsive way, and the second control group received no intervention.Results: Participants have average levels of empathy (score: 32 to 52) and strong prejudice (score: 0.08 to −0.87) towards persons with disabilities. The intervention results in a slight short-term effect for prejudice and sub-scale measurements of empathy. A slight improvement was noted in participants’ ability to transpose themselves imaginatively into the experience of disabled characters.Conclusion: The findings contribute to the understanding of empathy as a dynamic component that can be positively influenced by, for example, a serious game. These results have teaching implications on the facilitation of empathy. The short-term effect on empathy and prejudice towards persons with disabilities may contribute to bridge the inequality experienced by persons with disabilities.

Published: March 2019

Background: Because resources are limited in low- and middle-income countries (LMIC), the development of outcome measures is of interest. Wheelchair outcome measures are useful to support evidence-based practice in wheelchair provision.Objectives: The Wheelchair Interface Questionnaire (WIQ) is being developed to provide a professional perspective on the quality of the interface between a wheelchair and its user. This article discusses the development of the WIQ and its face and content validity.Method: During field studies in Kenya, we sought to include professional report data on the wheelchair–user interface that could be analysed to inform design changes. None of the existing measures was focused on the interface between users and their wheelchairs. The WIQ was developed to meet this need. To investigate face and content validity, 24 experienced wheelchair professionals participated in a study that included two rounds of an online survey and a focus group in Kenya.Results: Responses were categorised by topic and the WIQ was modified following each iteration. Participants affirmed the usefulness of a brief professional report measure to provide a snapshot of the user–wheelchair interface. Participants emphasised the importance of brevity, wide applicability and provision of specific feedback for wheelchair modification or design changes. The focus group agreed that the final version provided useful data and was applicable to virtually all wheelchair users in LMIC.Conclusion: These preliminary studies indicate initial face and content validity of the WIQ as a method for providing a professional perspective on the interface between a user and his or her wheelchair.

Abstract. Studies on goat milk have mainly focused on cosmopolitan breeds
and very limited information is available on local breeds, which is important
for biodiversity preservation and local cheese production. The aim of this
study was to evaluate the breed effect on milk yield, composition and somatic
cell score (SCS) of five local Italian goat breeds (Garganica, Girgentana,
Jonica, Maltese and Mediterranean Red) compared with a cosmopolitan
specialized dairy breed (Saanen). A total of 60 goats (10 per breed) from an
experimental farm were enrolled in the study. Milk yield, composition and SCS
were recorded and analyzed every 2 weeks during the entire lactation. Data
were analyzed using a mixed model with repeated measures. Saanen yielded
between 0.27 and 0.62 kg day−1 more milk than the local breeds. Among
local breeds, Maltese and Jonica were the most productive, with an average of
1.28 and 1.25 kg day−1, respectively, while Mediterranean Red,
Garganica and Girgentana produced ≤1 kg day−1. Saanen had the
highest SCS (6.81) and the lowest fat content (3.26 %). In relation to
protein, Garganica showed the greatest content (3.71 %), and Saanen had a similar content to other local breeds (3.42 %) except for Maltese, which
was lower (3.11 %). Saanen and Garganica had the lowest lactose
percentage (4.28 % and 4.26 %, respectively). All breeds followed a
similar pattern across lactation: SCS and fat and protein content peaked at
the end of the lactation, whereas lactose percentage was highest at the
beginning of the lactation. Differences between Saanen and the local breeds
for milk yield, composition and SCS were consistent across lactation. In
conclusion, local breeds produced less milk but with lower SCS and greater fat
and lactose content than the Saanen cosmopolitan breed, suggesting a better milk
quality.
Universal Computing Machine for Number Genetics in the Proportiones Perfectus Theory
Authors: Mamombe Lovemore 
Published: March 2019

The proportiones perfectus law states that σ_x^y=(x+√(x^2+4y))/2 is a proportione perfectus if 1≤y≤x such that for an arbitrary positive integer , there exists an integer sequence defined simultaneously by the quasigeometric relation h_(n+1)=round(σ_x^y h_n ),n≥1 and the arithmetic relation h_(n+2)=〖xh〗_(n+1)+〖yh〗_n,n≥1. When x=y=1 σ_x^y is the golden mean. When x=2,y=1,σ_x^y is the silver mean. In previous works we introduced the theory of number genetics – a framework of logic within which the golden section is studied. In this work we apply the concept to all proportiones perfectus. Let be defined as above. Furthermore, let h1 satisfy {█(round(h_1/(σ_x^y ))=w@round(wσ_x^y)≠h_1 ). ┤Now let H'nbe Hn with h1=1 Again let be defined as A robust universal computing machine is herein developed for the purpose of establishing the relationship h_i=g_(n+i-1)±h_i^',i,n≥1, which relationship is key to the logic protocol. It is clear therefore that this system of logic presents as the building block of every (including itself) within a particular σ_x^y regime. Clearly number genetics takes central place in the proportiones perfectus theory.
In Situ Regulating the Order–Disorder Phase Transition in Cs2AgBiBr6 Single Crystal toward the Application in an X‐Ray Detector

Published: March 2019

AbstractThe double perovskite Cs2AgBiBr6 single crystal holds great potential for detecting applications because of its low minimum detectable dose rate and toxic‐free merit. Nevertheless, the disordered arrangement of Ag+/Bi3+ usually gives rise to unexpected structural distortion and thereafter heavily influences the photoelectric properties of the Cs2AgBiBr6 single crystal. Herein, phenylethylamine bromide is demonstrated to be capable of in situ regulation of the order–disorder phase transition in the Cs2AgBiBr6 single crystal. The improved ordering extent of alternatively arranged [AgX6]5− and [BiX6]3− octahedra is theoretically and experimentally proven to decrease the defect density and suppress self‐trapped exciton formation, and thereby tune the band gap and enhance the carrier mobility, which consequently promotes its application in an X‐ray detector. The performance of a corresponding detector based on PEA‐Cs2AgBiBr6 single crystal displays superior performances, e.g., longer carrier drift distance, higher photoconductive gain, and faster current response (13 vs 3190 µs). Prominently, the as‐fabricated PEA‐Cs2AgBiBr6 single‐crystal X‐ray detector has an extremely high sensitivity with a value of 288.8 µC Gyair−1 cm−2 under a bias of 50 V (22.7 V mm−1), which largely outperforms those of their counterparts with lower ordering structure.
