Published: April 2021

Abstract. International Ocean Discovery Program (IODP) Expedition 357: “Serpentinization and Life” drilled shallow cores into the Atlantis
Massif near the Mid-Atlantic Ridge in October 2015 using seabed drills. Serpentinization and other geochemical processes occurring within the
Atlantis Massif release hydrogen, methane, and other chemicals that can
potentially fuel microorganisms through chemosynthesis. The subseafloor rock
cores collected during IODP Exp. 357 are the first of their kind, meaning
the analysis and interpretation of these samples required new methodologies,
including a specialized approach for distinguishing endemic subsurface
inhabitants from potential contaminants from various sources. Background
samples of various potential contamination sources were collected during
sampling: 109 samples of seawater collected before, during, and after
drilling; 20 samples of greases and oils associated with the drilling
equipment; and samples of the laboratory's ambient air. Despite the
widespread usage of drilling lubricants and the importance of controlling
contamination in drill-core samples for microbiological analyses, no studies
to date have looked at DNA in drilling greases and oils. In this study,
drilling lubricants were analyzed as possible sources of microbial
contamination of subseafloor rock core samples by environmental sequencing
of 16S rRNA genes. We find that microbial signatures from drilling
lubricants are only found in low abundance in seafloor samples (at most a
few percent of total sequence counts), with laboratory contaminants being a
greater source of contamination.

Obviation in Hungarian: what is its scope, and is it due to competition?
Authors: Szabolcsi Anna 
Published: April 2021

According to the classical description of obviation, the subject of a subjunctive is disjoint in reference from the attitude-holder subject of the immediately higher clause. *Je veux que je parte. I want that I leave.SUBJ ‘I want for me to leave’ Inspired by Ruwet (1984/1991) and Farkas (1988; 1992), I present data from Hungarian where obviation in certain subjunctives is plainly lifted, and data where obviation occurs in indicatives. I argue that obviation is not the result of competition with another construction, and point to promising potential accounts in terms of a clash in semantics or pragmatics. My aim is to contribute desiderata for a theory of obviation and exemptions from obviation in fairly informal terms.

Inclusive, Safe and Resilient Public Spaces: Gateway to Sustainable Cities?
Authors: Iqbal Asifa 
Published: April 2021

The rapid urbanization process of cities is majorly coupled with extreme climate change, housing shortage and urban safety issues. These issues are raising new challenges to address the capability of urban resilience. Enhancing Urban Safety and Security is one of the major principles addressed by UN-Habitat in Sustainable Development Goal number 11. Making cities safe and sustainable means ensuring access to safe and affordable public spaces for all. This book chapter aims to highlight how do the city’s public spaces are linked and affected by crime and fear of crime? How do crime and fear of crime interconnect to the built environment in cities while promoting positive urban transitions in terms of safe and sustainable cities? This book chapter explores answers to these questions through the parks and public spaces of the city as a case study. In other words, the book chapter deals with the issue of safety and security by (1) showing links between parks and public spaces, and crime and fear of crime, (2) highlighting how different attributes in the built environment can affect people’s perception of safety, (3) understanding socio-technical perspectives i.e., how technological systems and equipment’s (such as lighting sensors, security alarms, security electronic devices, closed-circuit television (CCTV), smartphones or other technological instruments) are influencing safety/security and sustainability, (4) demonstrating the issues and challenges found in Stockholm, Sweden, and, (5) providing recommendations on how these places can be planned and designed to become more sustainable.

Published: April 2021

The conservation of probiotic products requires low temperatures and suitable equipment that are less available in developing countries. The challenge today is to find a local food matrix that can also carry probiotics (microorganisms with benefits for consumers) in the gastro-intestinal tract. The study mainly focus in the current research was to study the use of honey as a food matrix to carry probiotics in treating the cardiovascular disease, hypercholestreolemia. Thus, this study aimed to assess the viability of Lactobacillus plantarum 29V and its in vivo hypocholesterolemic properties when contained in honey. The strain L. plantarum 29V was added in pasteurized honey and was studied its viability in honey and its impact on the physicochemical parameters of honey.¶
For in vivo studies, 0.5 mL of the pasteurized honey containing approximately 108 CFU/mL of L. plantarum 29V were administered to rats fed on a cholesterol-enriched diet (control diet+ pure cholesterol solution (0.04 g/mL) per day per rat) using a feeding syringe; the treatment lasted 4 weeks. Serum lipids were analyzed during the experiment. The results have shown that the probiotic strain L. plantarum 29V can survive in honey for 28 days without affecting the honey’s qualities. Even present in honey, this strain continues to lower serum total cholesterol, (VLDL +LDL)-cholesterol and triglycerides levels of hypercholesterolemic rats. In addition, HDL-cholesterol levels significantly increased, and the atherosclerosis index was significantly lowered. The present study revealed that honey could be used as a food matrix to carry the probiotic Lactobacillus plantarum 29V strain very well into the gastro-intestinal tract. Hence, a probiotic formulation made of pasteurized honey and L. plantarum 29V would be used to treat or prevent hypercholesterolemia if these effects are confirmed in Human beings.
Relationship between Facebook Usage and Academic Performance of College Students under the Royal University of Bhutan

Published: April 2021

The development of social media like Facebook has changed the lives of many people principally the students. Several opinions are shared on how social media have a negative consequence on college students and lead to worsening their academic performance. Facebook usage is extremely prevalent among most undergraduates and approximately 85% of students use it particularly the first-year college students as it offers students a feeling of community and friendship. Of the total 365 students surveyed, 344 were Facebook users while 21 were non-users. Majority of respondents having Facebook account use mobile phones i.e., 48% of total respondents, 42% use their personal laptops and remaining 10% use college computer. Students are more often subjected to reading social media updates than reading academic-related books. Hence, it revealed that those who spent more time on social media spent less time studying i.e., users spent 0.33 to 1-hour studying per day and non-users spent 2 to 5 hours studying. Pearson's correlation test showed that the time spent on Facebook was negatively associated with students’ GPA (r = -.198, p = .000). More the time a student invests on Facebook, the lower the average grade point will be. However, blocking Facebook is not a solution since students can easily access it via their mobile phones. As a result, rather than blocking the site, higher education institutions such as Universities and Colleges may encourage students to use Facebook for educational purposes by offering appropriate arrangements and training.

Abstract
Human activities and development have contributed to declines in biodiversity across the globe. Understanding and addressing biodiversity loss will require the mobilization of diverse knowledge systems.
While calls for interdisciplinary practices in environmental research date back decades, there has been a more recent push for weaving multiple knowledge systems in environmental research and management, specifically Indigenous knowledge systems (IKS) and Western sciences.
The use of multiple knowledge systems in environmental research can improve understanding of socio‐ecological connections, build trust in research findings and help implement evidence‐based action towards biodiversity conservation. Mobilizing multiple types of knowledge in environmental research and management can be beneficial; however, challenges remain.
There is a need to understand how and where studies have woven IKS and Western sciences together in order to learn about frameworks and processes used, and identify best practices.
Here, we present a protocol for a systematic map that will examine the extent, range and nature of the published literature that weaves IKS and Western sciences in terrestrial ecosystems research, monitoring and management in Canada.
The systematic map will aim to capture all available and relevant studies found in the published academic and grey literature. The search will use standardized search terms across four publication databases, four specialized websites and one web‐based search engine. Bibliographies of relevant review articles captured by our search strategy will be cross‐checked to identify additional studies. Calls for evidence among professional networks will also complement the search strategy. All searches will be conducted in English. Search results will be reviewed in two stages: (1) title and abstract and (2) full text. All screening decisions at the full‐text stage will be included into the map database.
The systematic map will use a narrative synthesis approach employing descriptive tables, statistics and figures (including a map with geospatially referenced studies) to summarize findings.
Results from this mapping exercise can serve to support environmental research and management efforts working across IKS and Western sciences by highlighting best practices, as well as evidence gaps.
Contemporary authorship guidelines fail to recognize diverse contributions in conservation science research

Abstract
Authorship should acknowledge and reward those deserving of such credit. Moreover, being an author on a paper also means that one assumes ownership of the content.
Journals are increasingly requiring author roles to be specified at time of submission using schemes such as the contributor roles taxonomy (CRediT) system, which relies on 14 different roles. Yet, there are many other aspects of research that are not adequately captured by the list of roles, particularly in applied environmental disciplines such as conservation science, environmental science and applied ecology.
The growing recognition that authorship should reflect contributions that extend beyond the usual data collection, analysis and writing provides the ideal backdrop for rethinking contributions in conservation science. Here we propose a more inclusive approach to authorship that recognizes and values diverse contributions and contributors using an expanded list of CRediT roles.

AbstractThe sub‐bandgap absorption and ultrafast relaxation in a GaAs/ErAs/GaAs heterostructure are reported. The infrared absorption and 1550 nm‐excited ultrafast photo‐response are studied by Fourier transform infrared spectrometry and time‐domain pump–probe technique. The two absorption peaks located at 2.0 (0.62 eV) and 2.7 µm (0.45 eV) are originated from the ErAs/GaAs interfacial Schottky states and the ErAs itself, respectively. The photo‐excited carrier lifetime, excited using 1550 nm light, is measured to be as low as 190 fs for the GaAs/ErAs/GaAs heterostructure, making it a promising material for 1550‐nm‐technology‐compatible, high critical‐breakdown‐field THz devices. The relaxation mechanism is proposed and the functionality of ErAs is revealed.
Over 30 000 h Device Lifetime in Deep Blue Organic Light‐Emitting Diodes with y Color Coordinate of 0.086 and Current Efficiency of 37.0 cd A−1

Published: April 2021

AbstractThe development of highly efficient and long‐life deep blue devices has been an ongoing challenge in the field of organic light‐emitting diodes (OLEDs) because of the short lifetime inherent to highly efficient blue devices. The efficiency and lifetime issues of the deep blue OLEDs are resolved in this work by engineering the device architecture by managing the triplet excitons of the phosphorescence and thermally activated delayed fluorescence (TADF) emitters. The CN‐modified imidazole type Ir emitter and boron‐based TADF emitter with similar emission energy are combined to develop an energy exchanging phosphorescence and TADF (EPHTADF) device. An emission mechanism inducing both forward and backward energy transfer concurrently between the Ir phosphor and TADF emitter shortens the triplet exciton lifetime of the two emitters, which dramatically enhances the device lifetime of the blue devices. Deep blue OLEDs triggering EPHTADF emission ultimately yields device performances including high current efficiency (CE) of 37.0 cd A−1, color‐coordinate corrected CE of 430.9 cd A−1, extrapolated device lifetime of more than 30 000 h, and deep blue color coordinates of (0.122, 0.086). This work demonstrates the potential of EPHTADF devices to serve as the solution to the problematic issues of the blue OLEDs.

AbstractA relay Cu(I)/Brønsted base catalyzed one‐pot phospha‐Michael addition/5‐exo‐dig cyclization/isomerization of in situ generated aza‐alkynyl o‐quinone methides (N‐o‐AQMs) from 1‐(o‐aminophenyl)prop‐2‐ynols with P(O)‐compounds has been established to afford C3‐phosphorylated indoles. It demonstrates that the 1,4‐conjugate addition adduct from N‐o‐AQMs could undergo further cyclization with the tethered alkyne moiety to afford N‐heterocyclic compounds.magnified image
Inverse Design of Diffractive Relativistic Meta‐Sails via Multi‐Objective Optimization
Authors: Salary Mohammad Mahdi , Mosallaei Hossein 
Published: April 2021

AbstractPhotonic propulsion of light sails using the radiation pressure of an intense laser beam is a promising route to achieve relativistic velocities for deep space exploration. A successful photonic design of such relativistic sails requires efficient acceleration and maintaining stability of the beam‐riding across a Doppler‐broadened propulsion band due to considerable red‐shift of the wavelength in the frame of the moving sail. While efficient acceleration of the sail requires maximizing the optical force along the beam propagation direction, the stability degree of the sail depends on the magnitude of lateral forces in the transverse plane of the beam. This establishes a trade‐off between these two requirements which calls for their synergistic engineering. In this work, an evolutionary multi‐objective optimization technique for the inverse design of diffractive relativistic meta‐sails with a genetic pixelated geometry is adopted. The goal is to identify a set of Pareto optimal solutions which provides the designer with an intuitive understanding of the ultimate trade‐off between acceleration and stability degree of the sail in a vast design space, and allows for a well‐informed decision on the best design given the requirements for the acceleration time and distance as well as the tolerance with respect to mispointings and misalignments.

Published: April 2021

AbstractManagement of manure and cereal rye (Secale cereale L.) has implications for crop production and nutrient cycling. This 1‐yr, full‐factorial experiment conducted in Pennsylvania quantified the effects of three management factors—(a) rye management (RyeM; early‐terminated cover crop [CC] vs. double crop harvested a week later [DC]), (b) manure application method (ManM; unincorporated broadcast manure [BM] vs. shallow disk injected manure [IM]), and (c) fall field operation prioritization (priority; manure priority [MP] manure application in late September with rye planting in mid‐October vs. rye priority [RP], rye planting in late September with manure application in early November)—on rye biomass, nutrient recovery, and forage yield and the effect of ManM and priority on DC forage nutritive value in a rye–corn (Zea mays L.) cropping sequence. This experiment was intended to be a repeated 2‐yr study, but due to MP treatment rye crop failure in the second year, the resulting 1‐yr dataset was analyzed to assess priority effects. Prioritizing rye planting in the fall with DC increased total forage production and apparent N recovery (ANR) when manure was broadcast. These results highlight the value of prioritizing fall rye planting in DC systems to increase rye spring biomass and nutrient recovery when manure is broadcast. More experiments should be conducted on fall field operation timing to develop reliable recommendations.

PremiseAs a leaf expands, its shape dynamically changes. Previously, we documented an allometric relationship between vein and blade area in grapevine leaves. Larger leaves have a smaller ratio of primary and secondary vein area relative to blade area compared to smaller leaves. We sought to use allometry as an indicator of leaf size and plasticity.MethodsWe measured the ratio of vein‐to‐blade area from the same 208 vines across four growing seasons (2013, 2015, 2016, and 2017). Matching leaves by vine and node, we analyzed the correlation between the size and shape of grapevine leaves as repeated measures with climate variables across years.ResultsThe proportion of leaf area occupied by vein and blade exponentially decreased and increased, respectively, during leaf expansion making their ratio a stronger indicator of leaf size than area itself. Total precipitation and leaf wetness hours of the previous year but not the current showed strong negative correlations with vein‐to‐blade ratio, whereas maximum air temperature from the previous year was positively correlated.ConclusionsOur results demonstrate that vein‐to‐blade ratio is a strong allometric indicator of leaf size and plasticity in grapevines measured across years. Grapevine leaf primordia are initiated in buds the year before they emerge, and we found that total precipitation and maximum air temperature of the previous growing season exerted the largest statistically significant effects on leaf morphology. Vein‐to‐blade ratio is a promising allometric indicator of relationships between leaf morphology and climate, the robustness of which should be explored further.
