Published: May 2024

ObjectivesTo depict the current state of global surgery opportunities in United States ACGME‐approved Otolaryngology residency programs and compare the characteristics of programs with and without these opportunities.MethodsIn this cross‐sectional analysis, websites of ACGME‐accredited Otolaryngology residency programs were analyzed for information on program size, rank, age, and geographic region as obtained through the Doximity platform in 2023. Additional parameters were obtained for programs listing global surgery opportunities such as funding, faculty oversight, location/region, focus, and relationship to the community served. Data were tabulated and analyzed in Microsoft Excel and Stata.ResultsOf the 131 ACGME‐accredited Otolaryngology residency programs, 26 (20%) of programs advertised a global surgery opportunity. Nine (35%) of these promoted funding, 15 (58%) offered a clinical focus, one (4%) offered a research focus, and 10 (38%) offered a combined approach. The Midwest region had the most programs with global surgery opportunities (n = 8, 31%). Less than half (42%) of programs had an established partnership with local partners within low and middle‐income countries (LMICs). When comparing programs, the average Doximity rank, average program age, and average program size of programs that offered global surgery opportunities was significantly higher than those that did not (37.2 vs. 71.5, 54 vs. 41, 19.5 vs. 13.7; all p < 0.05).ConclusionsApproximately one‐fifth of Otolaryngology training programs have a global surgery opportunity. Programs that offer these opportunities had a higher Doximity ranking, older program age, and a larger trainee cohort. These results highlight potential areas for expanding global surgery opportunities in academic institutions.Level of EvidenceNA Laryngoscope, 134:4501–4505, 2024

AbstractPast research has shown that the bilateral dorsolateral prefrontal cortices (dlPFC) are implicated in both emotional processing as well as cognitive processing,1,2,3 in addition to working memory4, 5. Exactly how these disparate processes interact with one another within the dlPFC is less understood. To explore this, we designed a task that looked at working memory performance during fMRI under both emotional and nonemotional conditions, and tested it in this preliminary report. Participants were asked to complete three tasks (letters, neutral images, emotional images) of the Sternberg Sorting Task under one of two trial conditions (sort or maintain). Regions of interest consisted of the left and right dlPFC as defined by brain masks based on NeuroSynth6. Results showed a significant main effect of the ‘sort’ condition on reaction speed for all three trial types, as well as a main effect of task type (letters) on accuracy. In addition, a significant interaction was found between trial type (sort) and task type (letters), but not for either of the picture tasks. Although preliminary, these results reveal a discrepancy between BOLD signal and behavioral data, with no significant difference in BOLD activity during image trials being displayed, despite longer response times for every condition. While these initial results show that the dlPFC is implicated in nonemotional cognitive processing, more research is needed to explain the lack of BOLD activation seen here for similar emotionally valanced tasks, possibly indicating the involvement of other brain networks.

Published: May 2024

AbstractPurposeTo address the limitations of spinal cord imaging at ultra‐high field (UHF) due to time‐consuming parallel transmit (pTx) adjustments. This study introduces calibration‐free offline computed universal shim modes that can be applied seamlessly for different pTx RF coils and spinal cord target regions, substantially enhancing spinal cord imaging efficiency at UHF.MethodsA library of channel‐wise relative maps for the cervical spinal cord (six datasets) and thoracic and lumbar spinal cord (nine datasets) was constructed to optimize transmit homogeneity and efficiency for these regions. A tailored B0 shim was optimized for the cervical spine to enhance spatial magnetic field homogeneity further. The performance of the universal shims was validated using absolute saturation based mapping and high‐resolution 2D and 3D multi‐echo gradient‐recalled echo (GRE) data to assess the image quality.ResultsThe proposed universal shims demonstrated a 50% improvement in efficiency compared to the default (zero phase) shim mode. homogeneity was also improved by 20%. The optimized universal shims achieved performance comparable to subject‐specific pTx adjustments, while eliminating the need for lengthy pTx calibration times, saving about 10 min per experiment.ConclusionThe development of universal shims represents a significant advance by eliminating time‐consuming subject‐specific pTx adjustments. This approach is expected to make UHF spinal cord imaging more accessible and user‐friendly, particularly for non‐pTx experts.
ASMTP: Anonymous secure messaging token‐based protocol assisted data security in swarm of unmanned aerial vehicles
Authors: Manikandan Kayalvizhi , Sriramulu Ramamoorthy 
Published: May 2024

AbstractSwarm of Unmanned Aerial Vehicles (UAVs) broaden the field of application in various fields like military surveillance, crop monitoring in agriculture, combat operations, etc. Unfortunately, they are becoming increasingly susceptible to security attacks, such as jamming, information leakage and spoofing, as they become more common and in more demand. So, there is a wider need for UAVs, which requires the design of strong security procedures to fend off such attacks and security dangers. Even though several studies focused on security aspects, many questions remain unanswered, particularly in the areas of secure UAV‐to‐UAV communication, support for perfect forward secrecy and non‐repudiation. In a battle situation, it is extremely important to close these gaps. The security requirements for the UAV communication protocol in a military setting were the focus of this study. In this paper, we present the issues faced by the UAV swarm, especially during military surveillance operations. To secure the communication link in UAV, a new protocol for UAV Swarm communication is proposed with anonymous secure messaging token‐based protocol (ASMTP). The proposed protocol secures UAV‐to‐base station communication and safeguards the metadata of the sender and receiver nodes. The proposed model maintains the confidentiality, integrity and availability of data in the UAV Swarm and achieves robustness. In addition, it provides a different strategy for the cybersecurity gaps in the swarm of UAVs during military surveillance and combat operations.

AbstractPolymer composites with thermal conductivity are attractive for heat dissipation in electronic devices. We prepared epoxy resin‐based composite films filled with polythiophene [poly(3‐hexylthiophene‐2,5‐diyl)] (P3HT)/graphene complex or aluminum nitride (AlN). The composite films were characterized by electron microscopic observation, thermogravimetric analysis, and thermal conductivity measurements. The addition of a small content of P3HT/graphene complex (<1 wt%) increased both the out‐of‐plane and in‐plane thermal conductivities of the epoxy resin. The addition of AlN also increased thermal conductivity, but ≥40 wt% was required to obtain thermal conductivity comparable with that of an epoxy resin film doped with 0.9 wt% P3HT/graphene complex. The present results illustrate the potential of P3HT/graphene complexes as fillers for improving the thermal conductivity of epoxy resins without affecting their insulating properties.Highlights
Polythiophene/graphene fillers increased epoxy resin films' thermal conductivity.
To raise the thermal conductivity of epoxy resin films high AlN content was needed.
In‐plane/out‐of‐plane epoxy resin films' thermal conductivities were evaluated.

Published: May 2024

AbstractThis study investigated the optimization of CuO and MgO nanoparticle reinforcement ratios within glass fiber‐reinforced polymer (GFRP) composites, and it examined the impact of the hybrid mixture of oxide powders on the mechanical properties of the GFRPs. The study aims to improve the mechanical properties of GFRPs by combining these two powerful nanofillers in various weight ratios to find the best combination to obtain the best fatigue life. Tensile‐tensile fatigue tests were conducted on 25 samples containing hybrid CuO and MgO nanoparticles ranging from 0.0 to 0.8 wt% in 0.2% increments. The test was conducted using a computer‐controlled servo‐hydraulic fatigue device. It was found that the GFRP composite reinforced with hybrid nanoparticles improved the fatigue life. The CuO proportion in the composites partially increased the brittleness properties, while the MgO proportion partially increased the stiffness according to the results. It was found that 0.6 wt% MgO–0.4 wt% CuO and 0.2 wt% MgO–0.6 wt% CuO GFRP composites demonstrated the highest fatigue life yielding at the 39.5k, and 13.7k cycle at 70%, and 80% load level, respectively. The best fatigue life was yielded at the 128k cycle with the 0.4 wt% MgO and 0.6 wt% CuO sample at the 60% load level. According to experimental hysteresis energy loss, 0.4 wt% MgO–0.2 wt% CuO GFRP composite was found to have the highest energy loss. The energy loss increased by approximately 51% in this composite compared to the non‐reinforced composite. The fracture surfaces of a fatigue sample were shown with the SEM image.Highlights
The GFRP composites were produced by combining MgO and CuO as a hybrid reinforcement.
Analyzed fatigue life using hysteresis curves and S–N graphs.
The fatigue life of GFRP composites was improved with hybrid nanofiller content.
As compared to separate reinforcements with CuO or MgO, the hybrid nanoparticle reinforcement enhanced fatigue life more.

Authors: Lee Moon‐Sub , Casler Michael D. , Lee DoKyoung 
Published: May 2024

AbstractSwitchgrass (Panicum virgatum L.), a valuable forage and bioenergy crop, is established more easily than other native perennial warm‐season grasses, but its establishment is still slower than that of annual crops. Vigorous switchgrass establishment is crucial for achieving its full potential yield and for effectively competing with weeds for water and nutrient availability. To satisfy this demand, ‘Independence’ (Reg. no. CV‐295, PI 704577) switchgrass was developed at the University of Illinois at Urbana‐Champaign. Independence was selected for establishment vigor, winter survivorship, and high biomass yield for two cycles from ‘Kanlow’. It is characterized by rapid establishment, robust seedling growth, and the capacity to achieve peak production by the second year. Independence is well adapted to USDA hardiness zones 5b–7b. In field experiments conducted from 2016 to 2017, averaged over seven locations and all years, Independence annually yielded 13 Mg ha−1 of biomass, outperforming ‘Cave‐in‐Rock’ by 31%, ‘Liberty’ by 15%, ‘Shawnee’ by 42%, ‘Summer’ by 81%, and ‘Sunburst’ by 129%. In wet marginal sites in Illinois from 2020 to 2023, Independence exhibited an average biomass yield of 12 Mg ha−1, outperforming Shawnee by 31%, Liberty by 27%, and Kanlow by 19%, indicating its potential use on less productive land for annual crops. Independence was publicly released by the University of Illinois at Urbana‐Champaign in October 2021.

A systematic literature review of research examining the impact of citizenship education on active citizenship outcomes
Authors: Jerome Lee , Hyder Faiza , Hilal Yaqub , Kisby Ben 
Published: May 2024

AbstractThis article reports on a systematic review of the evidence concerning the impact of citizenship education, specifically focusing on the effect of different teaching activities on a range of active citizenship outcomes. It provides a narrative synthesis of 109 articles in peer reviewed journals, representing a wide range of methodological approaches. The review was undertaken for a teacher audience and the research team identified four themes with practical implications. First, we discuss the significance of school ethos and distinguish between distinctive aspects of ethos in the literature including relationships between students and teachers, values and behaviours. Second, we explore some of the characteristics of successful projects, including detailed consideration of the type of projects selected for action by young people, the role of teachers, and the duration of projects. This discussion suggests that, whilst full project cycles (involving students identifying and researching areas for action and devising, implementing and reviewing action plans) are valuable, there is also evidence to suggest that short, partial projects may be easier to implement and still secure comparable benefits. Third, we consider the evidence about whether and how citizenship education can have some compensatory effect, closing the civic gap between different groups of young people. In the fourth theme we consider the wide range of teaching strategies which have been demonstrated to have some success in practice.Context and implicationsRationale for this studyThis literature review was undertaken on behalf of a teacher's organisation to consider the evidence base for citizenship education.Why the new findings matterThe review demonstrates the breadth of evidence for the positive impact of citizenship education and highlights several avenues for further exploration relating to school ethos, action projects and reducing inequalities.Implications for researchers and educational institutionsImplications for practice relate to the importance of how students perceive the ethos of the school as a whole, as well as their experiences when learning citizenship. This has specific implications for school leaders whose support is required to nurture a positive school ethos (beyond the formal curriculum). Implications for citizenship teachers include making use of short, partial active citizenship projects more routinely; and adopting strategies for closing the civic gap. Researchers are urged to move beyond large‐scale surveys to explore longitudinal studies in specific contexts to track impacts over time for different students.
Responsive materials nanoarchitectonics at interfaces
Authors: Ariga Katsuhiko 
Published: May 2024

AbstractAdvanced materials could perform functions in response to external stimuli. These are responsive materials. In order for us to develop advanced functional systems with a good responsive nature, we need to create a methodology that goes one step further. It is the artificial architecture of functional material systems based on the knowledge of nanotechnology. The task will be fulfilled by the new concept of nanoarchitectonics. Nanoarchitectonics integrates nanotechnology with various material sciences, basic chemistry, microfabrication techniques, and biological processes to architect functional material systems from atomic, molecular, and nanomaterial units. This review will deal with the nanoarchitectonics of responsive materials related with phenomena at interfaces. In order to demonstrate the effectiveness of responsive materials nanoarchitectonics at interfaces for functional systems of various sizes, this review article is organized by size for various functional systems. Specifically, this review has grouped them into (i) molecular level response, (ii) nanodevice level response, (iii) material level response, and (iv) living cell level response. If the social demand for these materials is fully recognized, such development is expected to efficiently progress. This review article would play a role in stimulating such development.
Building sustainable organizations online: How leaders embed sustainability into organizational culture in virtual contexts
Authors: Lizares Robert Edric Josef R. , Cuyegkeng Maria Assunta C. 
Published: May 2024

AbstractBusiness organizations may provide significant contributions toward sustainable development, and their leaders have a critical responsibility in incorporating sustainability into their organizational cultures. However, virtual collaboration creates specific challenges in this task. Although existing literature explores how sustainability is integrated into corporate culture in onsite contexts, a gap exists regarding this process in online teams. As such, this study explores how leaders embed sustainability into organizational culture in virtual contexts. Using thematic analysis on data gathered from interviews with 12 participants, this study suggests that leaders exhibit particular behaviors in this undertaking, including recognizing challenges, engaging employees, role modeling, crafting strategy and planning, monitoring and assessing performance, developing partnerships and activating internal communities, and aligning personal and organizational values. These may be further categorized into intrapersonal, interpersonal and functional leader behaviors, which remain salient in the new normal as organizations balance their virtual and face‐to‐face modes of interaction.
3D Tremella‐Like g‐C3N4/TiO2/HNTs Heterojunction Photocatalyst for Enhanced Photocatalytic Degradation of Rhodamine B From Water

Published: May 2024

AbstractAmong the traditional treatment processes for purifying wastewater contaminated with Rhodamine B (RhB), semiconductor photocatalysis is the most effective technology because it can oxidize organic pollutants and convert them into CO2, H2O, and other harmless molecules in a safe and efficient manner. According to literature research, it is feasible to enhance the performance of g‐C3 N4 as a photocatalyst by constructing a heterojunction with other photocatalytic materials. Morphological regulation of carbon nitride (g‐C3N4) is a viable strategy for improving its photocatalytic activities. By controlling the morphology of g‐C3N4, factors such as light absorption, specific surface area, charge separation, and reaction sites can be optimized to enhance its photocatalytic efficiency. Three‐dimensional tremella‐like carbon nitride (3DT‐CN) and 3D‐CN/TiO2/HNTs (halloysite nanotubes) were prepared using bubble templates and an impregnation method respectively. The Z‐scheme heterojunction structure constructed by 3D‐CN and TiO2 promotes electron‐hole separation. Catalytic experiments demonstrated that under irradiation for 120 min, the 3D‐CN/TiO2/HNTs catalyst could eliminate 86.48 % of Rhodamine B (RhB). Additionally, active radicals such as e‐, h+, ⋅OH, and ⋅O2‐ are involved in RhB degradation. Therefore, the three‐dimensional tremella‐like 3D‐CN/TiO2/HNTs heterojunction photocatalyst has great potential for environmental purification.
Synthesis of N‐Acyl Indole‐3‐Carboxaldehyde Derivatives and Polyvinyl Alcohol Acetalization with 1‐Propionylindole‐3‐Carboxaldehyde
Authors: Perwin Aashna , Mazumdar Nasreen 
Published: May 2024

AbstractA series of seven stable amide derivatives based on indole‐3‐carboxaldehyde were synthesized with high yields using various aliphatic and aromatic acyl chlorides, triethylamine and DMAP as the catalyst at room temperature. Structural characterization was performed using FT‐IR, 1 H‐NMR, 13C‐NMR and LC–MS techniques. To develop bioactive material, acetalization of water‐soluble polyvinyl alcohol was achieved by reacting one of the N‐acyl derivatives, 1‐propionylindole‐3‐carboxaldehyde, in the presence of a p‐TSA catalyst to form polyvinyl acetal with pendant bioactive groups. The polymer was analyzed using 1 H‐NMR, FT‐IR, TGA, DSC, FE‐SEM and EDX spectroscopic techniques. The polymer was water‐insoluble with enhanced thermal stability compared to pure polyvinyl alcohol. This approach for developing N‐acyl derivatives of indole‐3‐carboxaldehyde and then reacting one of the monomers with polyvinyl alcohol to improve its thermal properties and stability in humid conditions has proven successful.
