Authors: Price Carrie , Kudchadkar Sapna R. , Sharma Basyal Pragyashree , Nelliot Archana , Smith Madison , Friedman Michael , Needham Dale M. 
Published: April 2020

Background: Health care continuing education conferences are important educational events that present opportunities for structured learning, interactive sharing, and professional networking. Conference presenters frequently cite published literature, such as clinical trials, to supply an evidence-based foundation, with presenters’ slides often shared with conference attendees. By using social media, these conferences can have greater impact, assist in supporting evidence-based clinical practice, and increase stakeholder engagement.Case Presentation: The authors present a case of embedding a health sciences librarian into the Annual Johns Hopkins Critical Care Rehabilitation Conference. The librarian served multiple roles, including social media ambassador, conference exhibitor, and presenter. We explore how these roles contributed to the field of early rehabilitation research through information dissemination and education. We also address best practices for librarian support of the conference, with a discussion of tools, platforms, and work flows that were beneficial.Conclusions: Librarian integration facilitated education about bibliographic literature database content, database searching, critical appraisal, and reporting of search methodology. Additionally, the librarian contributed to real-time distribution of scholarly literature through proficiency with web platforms, citation management programs, and social media. Librarians’ expertise in information organization and dissemination, as well as various technology platforms, make them a valuable addition to health care conferences.

Laughter's Truths: Hurston, Ellison, and Open-Ended Dialogue
Authors: Ellis Juniper 
Published: April 2020

ABSTRACT
For Hurston and Ellison in laughter as for Mikhail Bakhtin in dialogue, every sounding includes and anticipates a response, revealing the “whole life” of a person or a nation. Hurston's and Ellison's presentation of humor also sharpens the conflictual nature of open-ended dialogue, presenting anger and aggression as an explicit aspect of humor. Challenging Dexter Gordon's suggestion that African American humor is “always making visible the invisible while masking its own anger and rage,” Hurston and Ellison use humor to unveil conflict. Hurston suggests that the men who ask the women for their “can” (buttocks) pretend to deride what they want but in fact elevate them. Ellison's black man laughing in a laughing barrel seems to show respect to those who would contain his laughter but actually shows derision. The world is turned backside forward and bottom up—detonating an open-ended “American joke” that is still ongoing.

Introduction:
Extra-articular scapula body fractures have been shown to have good outcomes with nonsurgical management. What is not known is whether routine postinjury imaging of these fractures is necessary for monitoring healing and alignment. As the shift toward providing cost-effective healthcare continues, we sought to evaluate if routine postinjury imaging of these fractures resulted in any change in management while secondarily evaluating the imaging for fracture patterns at risk of displacement.

Methods:
A retrospective review of all extra-articular scapula body fractures managed nonsurgically at our institution was performed from January 2013 to December 2017. We measured the glenopolar angle, lateral border offset, sagittal angulation, and translation on both injury CT scans and follow-up radiographs to evaluate if any displacement occurred. In fractures that displaced more than 10 mm or 10° in any measurement, we evaluated the fracture pattern to see if any particular pattern posed a risk for displacement. In addition, we evaluated the cost of imaging for all radiographs obtained in the follow-up period.

Results:
A total of 139 patients with 147 extra-articular scapula body fractures were included in our analysis. No patient experienced a change in management based on postinjury radiographs. A total of 120 patients underwent postinjury imaging with a total of 204 radiographic series ordered, equating to $172,769.50 in radiograph expenses. Final radiographs were obtained at an average of 48.4 days postinjury, and overall, no significant difference was observed (P < 0.05) in any radiographic measurement when compared with the initial injury imaging; however, when looking at fractures that displaced, transverse fracture patterns of the scapula body represented a risk factor for displacement (relative risk = 6.5).

Discussion:
Satisfactory outcomes have previously been demonstrated with nonsurgical management of scapula body fractures and for most of these injuries postinjury imaging may not be necessary or cost effective.

Net Zero Energy Buildings and Low Carbon Emission, a Case of Study of Madagascar Island
Authors: Kameni Nematchoua Modeste , Reiter Sigrid 
Published: April 2020

The buildings respecting the concept “Net Zero energy” are becoming more and more flowering in the world these last years. The main goal of this research is to evaluate the different possibilities of implementation of buildings with Net zero energy and low environmental impacts in Sub-Saharan Africa. The proposed building is 80% made of local materials with low carbon emissions and especially at lower cost. The optimization and modeling of the building is carried out by the Design Builder software, which is a world-renowned software in the field of optimization of comfort, cost, carbon reduction, etc. By fixing the insulation thickness up to 11 cm, cooling and heating energy are found equal to zero during the different operating seasons in this residential building. The results show that the optimal solution to consider a net zero energy building in Antananarivo city requires an additional expense estimated at 40% of the cost of buildings more conventional encountered in the island. This will save $475 each year starting in 2030, with 99% reduction in the CO2 release. The choice of local materials with low conductivity, low emissions, and low cost, has a significant impact on the implementation of a sustainable building, and more adapted to climate change concept.
Making Time on Mars
Authors: Mirmalek Zara 
Published: April 2020

An examination of how the daily work of NASA's Mars Exploration Rovers was organized across three sites on two planets using local Mars time.
In 2004, mission scientists and engineers working with NASA's Mars Exploration Rovers (MER) remotely operated two robots at different sites on Mars for ninety consecutive days. An unusual feature of this successful mission was that it operated on Mars time—the daily work was organized across three sites on two planets according to two Martian time zones. In Making Time on Mars, Zara Mirmalek shows that this involved more than a resetting of wristwatches; the team's struggle to synchronize with Mars time involved technological and communication breakdowns, informal workarounds, and extra work to support the technology that was intended to support people. Her account of how NASA created an entirely new temporality for the MER mission offers insights about the assumptions behind the organizational relationship between clock time and work.
Mirmalek, herself a member of the mission team, offers an insider's view of the MER workplace and community. She describes the discord among MER's multiple temporalities and examines issues of professional identity that helped shape the experience of working according to Mars time. Considering time and work relationships through a multidisciplinary lens, Mirmalek shows how contemporary and historical human–technology relationships inform assumptions about the unalterability of clock time. She argues that the organizational connection between clock time and work, although still operational, is outdated.
Palustrine forested wetland vegetation communities change across an elevation gradient, Washington State, USA
Authors: Hough-Snee Nate 
Published: April 2020

BackgroundForested wetlands support distinct vegetation and hydrology relative to upland forests and shrub-dominated or open water wetlands. Although forested wetland plant communities comprise unique habitats, these ecosystems’ community structure is not well documented in the U.S. Pacific Northwest. Here I surveyed forested wetland vegetation to identify changes in community composition and structure across an elevation gradient that corresponds to flooding stress, asking: (1) How do forested wetland plant communities change across an elevation gradient that corresponds to flood frequency and duration? (2) At what relative elevations do different plant species occur within a wetland?MethodsI measured overstory tree basal area and structure and understory vascular plant composition in three zones: wetland buffers (WB) adjacent to the wetland, an upper wetland (UW) extent, and a lower wetland (LW) extent, surveying individual trees’ root collar elevation relative to the wetland ordinary high-water mark (OHWM). I estimated understory plant species abundance in sub-plots and surveyed these plots’ height above the OHWM. I used non-metric multidimensional scaling ordination to identify patterns in vegetation communities relative to wetland elevation, and tested for compositional differences between the WB, UW and LW zones using PERMANOVA. I calculated overstory and understory indicator species for each wetland zone using indicator species analysis.ResultsForest overstory composition changed across the elevation gradient, with broad-leaved trees occupying a distinct hydrologic niche in low-lying areas close to the OHWM. Conifer species occurred higher above the OHWM on drier microsites.Pseudotsuga menziesii(mean elevation = 0.881 m) andTsuga heterophylla(mean elevation = 1.737 m) were overstory indicator species of the WB, whileFraxinus latifolia(mean elevation = 0.005 m) was an overstory indicator for the upper and lower wetland. Understory vegetation differed between zones and lower zones’ indicator species were generally hydrophytic species with adaptations that allow them to tolerate flooding stress at lower elevations. Average elevations above the OHWM are reported for 19 overstory trees and 61 understory plant species. By quantifying forested wetland plant species’ affinities for different habitats across an inundation gradient, this study illustrates how rarely flooded, forested WB vegetation differs from frequently flooded, LW vegetation. Because common management applications, like restoring forested wetlands and managing wetland responses to forest harvest, are both predicated upon understanding how vegetation relates to hydrology, these data on where different species might establish and persist along an inundation gradient may be useful in planning for anticipated forested wetland responses to restoration and disturbance.

Aims: The objective of this work was to evaluate heart rate variability (HRV) in critically-ill neonates admitted to NICU, to detect the effect of different causes of critical illness on cardiac autonomic function and outcome of these neonates.
Study Design: Case-control study.
Place and Duration of Study: Neonatal Intensive Care Unit (NICU) of Pediatric Department, Tanta University Hospital, in the period from January 2018 to May 2019.
Methodology: We included 30 neonates who were critically-ill according to Score for Neonatal Acute Physiology with Perinatal Extension II (SNAPPE-II score) as cases Group. Fifteen healthy full term neonates, matched for age and sex, were enrolled as a control group. 24-hour Holter monitoring was performed with recording and interpretation of ECG data for every neonate in the study, including analysis of HRV.
Results: There was significant increase of mean HR in critically-ill neonates as compared to control group. There was significant decrease of all HRV parameters (SDNN, SDANN, SDNNI, RMSSD and PNN50) in critically-ill neonates as compared to control group (P< 0.05). Significant negative correlations between SNAPPE-II score and HRV parameters (SDNN, SDANN, SDNNI, RMSSD, PNN50) in critically-ill neonates were present, whereas there was non-significant positive correlation between SNAPPE-II score and mean heart rate.
Conclusion: HRV parameters decreased significantly in critically-ill neonates admitted to NICU, denoting severe cardiac autonomic dysfunction in these sick newborn infants. HRV strongly correlated to severity (SNAPPE-II score) and outcome, with strong relation to mortality of these critically-ill neonates.

Published: April 2020

Aim: The aim of the study was to investigate the circumferential anthropometric body characteristics of adult male Ijaws of southern Nigeria.
Methodology: The research design was a non-experimental, cross-sectional design. It made use of a total number of four hundred (400) subjects whose ages ranged between 21 to 40 years with BMI of 18.50 to <30.00. Individuals whose BMI fell within the category of overweight according to conventional BMI classification were included in the study because they looked apparently healthier than those with BMI classified as normal. Minimum sample size was determined using the Taro Yamane’s formula. Circumferential body anthropometric measurements and BMI were taken using stadiometer, digital calipers, calibrated flexible meter tape and weighting scale. Statistical analysis was done using statistical package for the social science (SPSS version 25.0) and Microsoft Excel 2019. Continuous variables were presented as mean±SD; minimum and maximum. Age was categorized into two groups (21 – 30 and 31 – 40) years while Body Mass Index (BMI) was also categorized into two; normal weight (18.5 – 24.9) and slightly overweight (25.0 – 30.7). Independent sample t-test was therefore carried out to determine significant difference in the measured anthropometric parameters according to age. The confidence interval was set at 95%, therefore p< 0.05 was considered significant.
Results: Results were presented in tables. Age and BMI were had no impact on the studied anthropometric parameters as there were no statistically significant difference seen when compared across age and BMI groups. On comparison with other racial populations, racial variation was observed.
Conclusion: Circumferential anthropometric studies are mainly used to demonstrate health status, growth rate and other population demography. This study catalogued anthropometric description of body circumference of the Ijaw ethnic group. These anthropometric values will be useful in medical studies and forensics.

AbstractPurposeTo investigate planning time and number of optimizations in routine clinical lung cancer plans based on the plan quality improvements following each optimization.Materials and methodWe selected 40 patients with lung cancer who were treated with conventional fractionated radiotherapy (CFRT). The 40 plans (divided into two groups with one or two target volumes) were completed by 9 planners using volumetric modulated arc therapy (VMAT). A planning strategy, including technique script for each group and a planning process for data collection, was introduced. The total planning time, number of optimizations, and dose–volume parameters of each plan were recorded and analyzed. A plan quality metric (PQM) was defined according to the clinical constraints. Statistical analysis of parameters of each plan following each optimization was performed for evaluating improvements in plan quality.ResultsAccording to the clinical plans generated by different planners, the median number of optimizations of each group was 4, and the median planning time was approximately 1 h (68.6 min and 62.0 min for plans with one or two target volumes, respectively). The dose deposited in organs at risk (OARs) gradually decreased, and the PQM values gradually improved following each optimization. The improvements were significant only between adjacent optimizations from the first optimization (Opt1) to the third optimization (Opt3).ConclusionIncreasing the number of optimizations was associated with significantly improved sparing of OARs with slight effects on the dose coverage and homogeneity of target volume. Generally, based on the designed planning strategy, there was no significant improvement of the plan quality for more than three optimizations.

Published: April 2020

ObjectiveIn a few studies, high‐intensity exercise has displayed beneficial effects on cardiovascular health among patients with rheumatic diseases, yet the high‐intensity exercise mode is still not fully accepted among health care professionals. The aim of this study was to investigate experiences of high‐intensity exercise among patients with axial spondyloarthritis.MethodsFourteen respondents who had participated in a high‐intensity exercise program for 12 weeks were included in this qualitative study with individual semistructured, in‐depth interviews. The respondents’ median age was 53, ranging from 23 to 63 years old, and both men and women of different ethnicities were represented. Interviews were analyzed by qualitative content analysis, including both manifest content and interpretations of underlying latent meaning.ResultsThe analysis resulted in five categories describing the respondents’ experiences with high‐intensity exercise: 1) high‐intensity exercise as a challenge for both body and mind, 2) increased faith in one's own body, 3) changed attitude toward exercise, 4) taking charge of one's own health by challenging the disease, and 5) exercise in a social context.ConclusionSupervised high‐intensity interval exercise was perceived as challenging for both body and mind but was also described as a positive experience, with rapid bodily effects that strengthened respondents’ faith in their own bodies. The new experience seemed to have changed the respondents’ attitude and motivation for exercise and made them start taking charge of their health by challenging the disease. Exercise in a social context, under professional leadership, enhanced exercise self‐efficacy and helped the respondents to adhere to the exercise program.

Published: April 2020

Abstract2D van der Waals materials have attracted increasing attention in recent years due to their exciting physical properties and offer new opportunities for creating devices with enhanced or novel functionalities. In particular, α‐MoO3 is an emerging member of the fast‐growing 2D family with strong natural anisotropic optical properties. However, anisotropic optical properties of ‐MoO3 in the visible frequency range remain elusive. Here, α‐MoO3 is investigated as an optical material at the visible frequency (450–750 nm), which exhibits a polarization‐dependent complex refractive index due to the anisotropic crystal structure. As a proof of concept, polarization‐sensitive photonic devices including polarization reflectors and polarization color filters are designed and realized by constructing metal–insulator–metal Fabry–Perot cavities. It is observed that resonance frequencies for designed transmission and reflection filters change up to 25 nm with incident polarization which stems from the polarization‐dependent complex refractive indices of α‐MoO3. The largest contrasts are observed for two orthogonal polarization states parallel to the two orthogonal in‐plane crystal directions. The approach in this study offers new directions for potential applications in the development of polarization‐dependent devices based on 2D van der Waals materials for visible frequencies.

Published: April 2020

AbstractEnantioselective allylation of aldehydes and ketones is a widely used approach for preparing chiral homoallylic alcohols, however, most of the reactions are still mainly performed in organic solvents. Considering their environmental impact, expansion of synthetic technology in water has the highest priority in the organic chemistry field. Here, we report enantioselective reaction of water‐stable amido‐functionalized allylboronates with acetophenone derivatives in water. The reaction was catalyzed with zinc hydroxide and a didecylamino‐functionalized chiral aminophenol reagent, affording a variety of homoallylic alcohols in up to 99% yield. There is a definite proportional correlation between the enantioselectivity and the size of an ortho‐substituent on the substrate, and the enantiomeric excess of the product reached up to 98%.magnified image
Correlating Macro and Atomic Structure with Elastic Properties and Ionic Transport of Glassy Li2S‐P2S5 (LPS) Solid Electrolyte for Solid‐State Li Metal Batteries

Published: April 2020

AbstractA combination of high ionic conductivity and facile processing suggest that sulfide‐based materials are promising solid electrolytes that have the potential to enable Li metal batteries. Although the Li2S‐P2S5 (LPS) family of compounds exhibit desirable characteristics, it is known that Li metal preferentially propagates through microstructural defects, such as particle boundaries and/or pores. Herein, it is demonstrated that a near theoretical density (98% relative density) LPS 75‐25 glassy electrolyte exhibiting high ionic conductivity can be achieved by optimizing the molding pressure and temperature. The optimal molding pressure reduces porosity and particle boundaries while preserving the preferred amorphous structure. Moreover, molecular rearrangements and favorable Li coordination environments for conduction are attained. Consequently, the Young's Modulus approximately doubles (30 GPa) and the ionic conductivity increases by a factor of five (1.1 mS cm−1) compared to conventional room temperature molding conditions. It is believed that this study can provide mechanistic insight into processing‐structure‐property relationships that can be used as a guide to tune microstructural defects/properties that have been identified to have an effect on the maximum charging current that a solid electrolyte can withstand during cycling without short‐circuiting.
