Authors: Bharati Ashim Jyoti , Khanikar Rakesh Ruchel , Bailung Heremba , Sankaranarayanan Kamatchi 
Published: September 2023

AbstractCold atmospheric plasma (CAP) has gained significance in recent years and different prospects of it have been studied widely owing to its effectiveness and eco‐friendly nature. CAP has been used extensively in wound healing. However, a detailed understanding of the interaction of the CAP with different protein macromolecules present in our body is essential. In this study, we emphasize how CAP affects the protein fibrinogen. Fibrinogen is a major protein involved in blood clotting and the major protein in the blood. Numerous spectroscopic investigations have been done including UV spectroscopy, fluorescence spectroscopy, dynamic light scattering (DLS), and Zeta. This work shines a light on protein self‐assembly to bring the future possibilities of bio‐medicine with CAP treatment. Fibrinogen undergoes structural changes around tryptophan residue as evidenced by UV spectroscopy and quenching in fluorescence spectroscopy. The order of the fluorescence quenching is Oxygen > Helium > Argon gas plasma. 2,4‐dinitrophenylhydrazine (DNPH) assay supports fluorescence studies as more protein carbonyls are formed in the case of argon and oxygen gas plasma. DLS and Zeta potential measurements prove that the protein Fibrinogen undergoes a self‐assembly process to form organized assemblies in the presence of a plasma jet. Reactive oxygen and reactive nitrogen species produced in the plasma have been evaluated using various assays and correlated with the other studies. This study will help understand protein fibrinogen's self‐assembly process and pave the way for the CAP application in wound healing.

AbstractMagneto‐optical microscopies, including optical measurements of magnetic circular dichroism, are increasingly ubiquitous tools for probing spin‐orbit coupling, charge‐carrier g‐factors, and chiral excitations in matter, but the minimum detectable signal in classical magnetic circular dichroism measurements is fundamentally limited by the shot‐noise limit of the optical readout field. Here, a two‐mode squeezed light source is used to improve the minimum detectable signal in magnetic circular dichroism measurements by 3 decibels compared with state‐of‐the‐art classical measurements, even with relatively lossy samples like terbium gallium garnet. These results provide a framework for new quantum‐enhanced magneto‐optical microscopies that are particularly critical for environmentally sensitive materials and for low temperature measurements where increased optical power can introduce unacceptable thermal perturbations.

Published: September 2023

AbstractThe World Health Organization (WHO) adopted a global noncommunicable disease monitoring framework in 2013 with a target of a 25% reduction in premature mortality from four noncommunicable diseases (NCDs) such as cancer, diabetes, cardiovascular disease (CVD) and chronic respiratory disease (CRD) by 2025 compared to 2010. The Sustainable Development Goals (SDGs) target to reduce premature deaths from the four major NCDs by one‐third from 2015 to 2030. The objective of this study was to estimate the trend and reduction in premature mortality in India due to 4 major NCDs combined and separately between 2001 and 2030 and compare its progress toward the WHO and SDG target achievement. The publicly available data from the census for population and the Sample Registration System (SRS) for cause of death by 5‐year‐age groups were extracted. Age standardized premature mortality rates, unconditional probability of dying and annual percent change (APC) were computed. The premature mortality for four major NCDs decreased by −13.9% from 2010 to 2025 and by −15.6% from 2015 to 2030. The percentage changes in premature mortality from 2010 to 2025 were −33.9%, −17.4%, −9.3%, and 6.9% for CRD, cancer, CVD and diabetes respectively. For 2015–2030, these changes were −21.7%, −11.5%, −15.4%, and −15.1%. A significant reduction trend was observed for CRD with an average APC of −5.2%. The current reduction trend in premature mortality indicates that either the 25% reduction by 2025 or a one‐third reduction by 2030 will require intensive implementation of policies and program for NCD reduction.
Performance metrics in strategy research: A new metric and method for assessing dynamic value
Authors: Souder David , Shaver J. Myles , Harris Jared D. , Alrashdan Abdullatif 
Published: September 2023

AbstractResearch SummaryWe discuss two research design considerations that jointly influence the choice of financial performance metrics in strategy research: (a) expected temporal payoff of the strategic choice and (b) source of variation invoked in the research design (i.e., within‐firm vs. between‐firm comparisons). We map existing performance metrics commonly used in the research literature to these considerations, and highlight the lack of performance metrics well suited for the combination of strategies with not‐well‐defined temporal payoffs and within‐firm research designs. To remedy this, we introduce a value partitioning methodology that provides a performance metric we call dynamic value. We apply this methodology and demonstrate how it generates additional insights about how cash holdings affect firm performance.Managerial SummaryThis article introduces the value partitioning methodology for interpreting two distinct elements of stock market valuations: (a) the firm's implied future value from continuing operations in a “steady state” and (b) the market's estimate of dynamic future value associated with the firm's strategic choices or competitive positioning. We describe situations where the latter element is useful for measuring strategy performance. We apply this methodology and demonstrate how it generates additional insights about how cash holdings affect firm performance.
Entrepreneurial framing: How category dynamics shape the effectiveness of linguistic frames
Authors: Taeuscher Karl , Rothe Hannes 
Published: September 2023

AbstractResearch SummaryHow do new entrepreneurial ventures effectively deploy linguistic frames to attract customer demand? Drawing on framing and categories research, we develop and test theory about how category dynamics shape the effectiveness of two commonly observed frames—social impact framing and innovativeness framing—in the context of prosocial categories. We test our predictions by tracking entrepreneurial ventures in the market category for massive open online courses over the category's first 10 years of existence (2012–2021). Our fixed‐effects models show that higher levels of category salience increase the effectiveness of a social impact framing but decrease the effectiveness of an innovativeness framing; conversely, higher levels of category crowdedness decrease the effectiveness of a social impact framing but increase the effectiveness of an innovativeness framing.Managerial SummaryThis research explores how startups can strategically frame themselves to attract customers. We specifically compare the effectiveness of a “social impact framing” (emphasizing the startup's benefits to society) versus an “innovativeness framing” (emphasizing innovativeness) under different market conditions. Our longitudinal study finds that startups benefit most from a social impact framing when their market attracts a lot of attention or has low competition. While an innovativeness framing can backfire under such conditions, it effectively helps to attract customers in a market that receives little attention or exhibits fierce competition. Entrepreneurs and managers can leverage our insights to more effectively tailor their framing strategies to their market environment and ultimately gain more customer traction.
Technology adoption and innovation: The establishment of airmail and aviation innovation in the United States, 1918–1935

Published: September 2023

AbstractResearch SummaryThis article explores how technology adoption can shape innovative activity. We study this issue within the historical context of the introduction and expansion of airmail across the United States between 1918 and 1935 using archival material and a novel dataset of early 20th century patents. A joint qualitative and quantitative investigation indicates that local individual and corporate actors applied diverse pools of knowledge and intensified their work with aviation innovations following airmail entry into their county. Moreover, we find evidence that the co‐location of aircraft manufacturing and airmail operations was associated with more corporate innovations that facilitated economies of scale and corresponded to increased technological diversification of firms' aviation patent portfolios. Ultimately, this paper deepens our understanding of the antecedents, consequences, and organizational processes that underpin innovation.Managerial SummaryThis research investigates how aviation innovation in the United States was influenced by the postal service's early 20th century introduction and expansion of airmail routes. Our results indicate that counties with an airmail route experienced increased aviation‐related patenting by individual and corporate inventors relative to similar counties that did not receive an airmail route. Moreover, we find that corporate inventors working in airmail counties that also contained aircraft manufacturers were particularly active in technological areas that enhanced aircraft economies of scale and patented in a wider range of aviation‐related domains. An implication of this work for managers and policymakers is that early access to nascent technology can be a driver of local innovation and that spillovers can benefit diverse economic actors working in close proximity.

Published: September 2023

AbstractPhosphorene is a 2D phosphorus atomic layer arranged in a honeycomb lattice like graphene but with a buckled structure. Since its exfoliation from black phosphorus in 2014, phosphorene has attracted tremendous research interest both in terms of synthesis and fundamental research, as well as in potential applications. Recently, significant attention in phosphorene is motivated not only by research on its fundamental physical properties as a novel 2D semiconductor material, such as tunable bandgap, strong in‐plane anisotropy, and high carrier mobility, but also by the study of its wide range of potential applications, such as electronic, optoelectronic, and spintronic devices, energy conversion and storage devices. However, a lot of avenues remain to be explored including the fundamental properties of phosphorene and its device applications. This review recalls the current state of the art of phosphorene and its derivatives, touching upon topics on structure, synthesis, characterization, properties, stability, and applications. The current needs and future opportunities for phosphorene are also discussed.
Launching a Drop via Interplay of Buoyancy and Stick‐Jump Dissolution
Authors: Zeng Binglin , Yang Haichang , Xu Ben Bin , Lohse Detlef , Zhang Xuehua 
Published: September 2023

AbstractAccording to Archimedes' principle, a submerged object with a density lower than that of aqueous acid solution is more buoyant than a smaller one. In this work, a remarkable phenomenon is reported wherein a dissolving drop on a substrate rises in the water only after it has diminished to a much smaller size, though the buoyancy is smaller. The drop consisting of a polymer solution reacts with the acid in the surrounding, yielding a water‐soluble product. During drop dissolution, water‐rich microdroplets form within the drop, merging with the external aqueous phase along the drop‐substrate boundary. Two key elements determine the drop rise dynamics. The first is the stick‐jump behavior during drop dissolution. The second is that buoyancy exerts a strong enough force on the drop at an Archimedean number greater than 1, while the stick‐jump behavior is ongoing. The time of the drop rise is controlled by the initial size and the reaction rate of the drop. This novel mechanism for programmable drop rise may be beneficial for many future applications, such as microfluidics, microrobotics, and device engineering where the spontaneous drop detachment may be utilized to trigger a cascade of events in a dense medium.

Published: September 2023

AbstractIn the recent times research towards solid state supercapacitors (SSS) have increased drastically due to the promising performance in futuristic technologies particularly in portable and flexible electronics like smart watches, smart fabrics, foldable smartphones and tablets. Also, when compared to supercapacitors using liquid electrolyte, solid electrolyte has several advantages like high energy density, safety, high cycle life, flexible form factor, and less environmental impact. The crucial factor determining the sustainability of a technology is the eco‐friendliness since the natural resources are being exploited in a wide scale. Numerous studies have focused on biodegradable materials for supercapacitor electrodes, electrolytes, and other inactive components. Making use of these biodegradable materials to design a SSS enables the technology to sustain for a very long time since biodegradable materials are not only environment friendly but also, they show relatively high performance. This review focuses on recent progress of different biodegradable electrodes, and electrolytes along with their properties, electrochemical performance and biodegradable capabilities for SSS have been analyzed and provides a concise summary enabling readers to understand the importance of biodegradable materials and to narrow down the research in a more rational way.
Exploring the role of high school engineering courses in promoting science attitudes for students with learning disabilities

Published: September 2023

AbstractDemand for engineering‐interested and proficient high school graduates continues to grow across the nation. However, there remains a severe gap in college participation and employment in engineering fields for students with learning disabilities (SWLDs). One potential way to encourage SWLDs to consider engineering as a profession and promote the development of key science attitudes may be through engineering and technology career and technical education (E‐CTE) coursework. In this study, we address the following research questions: Do SWLDs take E‐CTE courses in the early years of high school at different rates compared to students without learning disabilities? What is the relationship between early E‐CTE coursetaking and science attitudes (self‐efficacy, utility, identity), and does this differ for students with and without learning disabilities? How do specific engineering career expectations change with respect to enrollment in early E‐CTE coursework, and do these differ for students with and without learning disabilities? We utilize the High School Longitudinal Study of 2009 (HSLS) to respond to the research questions through moderation models and a student fixed effects methodology. Ultimately, we found no evidence of SWLD underrepresentation in E‐CTE in high school. However, SWLDs were expected to benefit more than the general population from E‐CTE participation with respect to higher levels of science self‐efficacy and science identity. Implications from these findings include how to encourage persistence along the engineering pathway, the growth of career pathway policies at the state level, and how to incorporate E‐CTE practices in academic courses.
Urgent call for protection and use of transboundary watercourses. Some legal reflections
Authors: Ha Thanh Hoa , Vu Van Tuan 
Published: September 2023

AbstractThe use of transboundary water resources has received special international attention in recent years. Although riparian countries recognize the benefits of cross‐border rivers and enter into agreements with countries sharing the transboundary rivers by means of legal rules, treaties, and principles, they have done excessive riverine exploitation activities to maximize their socio‐economic benefits, causing the imbalance in the ecosystems and peace. This study aims to conduct a secondary analysis of primary qualitative data to research the common legal frameworks on international water law such as Helsinki Rules, UN Watercourses Conventions, and UNECE Water Convention, together with a case study on the Mekong River Agreement. Bilateral, multilateral, international treaties and principles are currently not enforceable enough to compel riparian countries strictly to comply with these legal rules and principles on equitable and sustainable water coordination and development. Besides, there are still internal conflicts among the upper and lower riparian countries over the equitable and reasonable use of transboundary river watercourses due to lack of punitive sanctions. There is an urgent need to establish a specialized international water management commission designated by all nations with the utmost power to regulate human‐related activities concerning transboundary watercourses to govern equitable and sustainable management and development of the transboundary water use. Besides, current international law principles have to be revised to fill the gap of disagreement and potential conflicts between upstream, middle stream and downstream countries.

Published: September 2023

AbstractWe report on the structural and magnetic properties of Li5+xFe1−xCoxO4 (0≤x≤1).< The system assumes two distinct crystal structures at room temperature (α and β), and shows a transition in preference from α to β between x=0.18 and x=0.25. This tendency is supported by DFT‐calculations. Upon heating, Li5FeO4 undergoes a reconstructive transition from α→β at ∼1060 K, while Li6CoO4 shows an order‐disorder transition from β→ϵ at ∼885 K, where ϵ is a cubic cation‐disordered antifluorite structure. Li5.50Fe0.50Co0.50O4 is stabilised towards the ordered β‐phase until at least 1170 K. XANES‐measurements confirm that the oxidation states of Fe and Co remain unchanged throughout the series with charge compensation from additional Li+ on increasing x. Magnetic measurements show onset of low‐temperature antiferromagnetic ordering around 3 K to 12 K. The magnetic structure of Li5FeO4 is described on the basis of powder neutron diffraction at 1.5 K, while the magnetic structures of Li5.50Fe0.50Co0.50O4 and Li6CoO4 are found to be slightly incommensurate below the ordering temperature.
How Dual-Tasking Using VR Affects the Elderly: A Systematic Review
Authors: Choi Jun-Su , Jung Min-Ye , Kim Junghun Aj 
Published: September 2023

AbstractThis study systematically reviewed research that applied dual-task interventions using VR technology for balance and cognitive tasks among older adults. Ten databases were searched following the PRISMA guideline, and 18 studies were selected based on their evidence levels and risk of bias. The selected studies consisted of 10 RCTs, 6 non-randomized controlled trials, and one each of case and qualitative studies. The types of balance tasks included standing and sitting postures, and all studies utilized cognitive tasks that required concentration. A total of 30 physical assessment tools and 42 cognitive assessment tools were identified. The results showed that virtual reality interventions improved balance and cognitive abilities among older adults and had a positive effect on fall prevention. These findings suggest that VR technology can be an effective tool for improving the physical and cognitive health of older adults.
Accelerating black holes in 2 + 1 dimensions: holography revisited
Authors: Arenas-Henriquez Gabriel , Cisterna Adolfo , Diaz Felipe , Gregory Ruth 
Published: September 2023

Abstract
This paper studies the holographic description of 2 + 1-dimensional accelerating black holes. We start by using an ADM decomposition of the coordinates suitable to identify boundary data. As a consequence, the holographic CFT lies in a fixed curved background which is described by the holographic stress tensor of a perfect fluid. We compute the Euclidean action ensuring that the variational principle is satisfied in the presence of the domain wall. This requires including the Gibbons-Hawking-York term associated with internal boundaries on top of the standard renormalised AdS3 action. Finally, we compute the entanglement entropy by firstly mapping the solution to the Rindler-AdS spacetime in which the Ryu-Takayanagi surface is easily identifiable. We found that as the acceleration increases the accessible region of the conformal boundary decreases and also the entanglement entropy, indicating a loss of information in the dual theory due to acceleration.
