Published: August 2022

AbstractNatural fiber composites are named sustainable, renewable environmentally friendly materials. Machining the fiber reinforced composite is difficult due to their anisotropic and heterogeneous nature. Computer numerical controlled drilling caused severe delaminating at the entry and exit of the drilled hole. These can be minimized in several ways such as process parameters, fabrication method, and reinforcement arrangements (Orientation/Treatment/Aspect ratio/Fiber volume fraction). Thrust force and torque are caused machining of composites, it can be controlled by spindle speed, feed rate, and cutting velocity. It has been observed that the output responses such as thrust, torque, delamination peel up and push out of composites depend on the diameters of the drill bit (6, 8, 10 mm), cutting speeds (1000, 2000, 3000 rpm), and feeds (10, 20, 30 mm/min). Total 27 numbers of holes were drilled based on Taguchi L‐27 factorial design orthogonal array. Response surface methodology has been employed to compare input drilling parameters and output responses. It is found that a smaller diameter drill bit of 6 mm with a higher speed of 3000 rpm and lesser feed of 10 mm/min produced high‐quality holes.

AbstractBackgroundTramadol, a weak opioid, inhibits the reuptake of serotonin, a key feature on vascular homeostasis. A suspected interaction exists between dabigatran and tramadol, which might trigger an excess on risk of bleeding however, there is a gap in knowledge on this topic.PurposeTo estimate the effects of tramadol, dabigatran and concomitant use on the risk of hospitalized major bleeds (Gastrointestinal bleeding and intra‐extracranial bleeds).MethodsAmong a validated established cohort of new users of oral anticoagulants for non‐valvular atrial fibrillation (NVAF) aged 18 years or older, we identified all hospitalized bleed episodes (GIB and extra/intracranial bleeds) within 2008–2015. A nested case–control analysis was conducted using conditional logistic regression. Adjusted odds ratios (aORs) with 95% confidence intervals (CIs) were calculated for dabigatran, tramadol, and concomitant use. Several sensitivity analyses were carried out.ResultsaORs (95%CIs) for current use of only dabigatran, only tramadol and concomitant users were 1.73 (1.37–2.18) and 1.38 (1.13–1.67) and 2.04 (0.74–5.67) compared with non‐users of both drugs (>365 days). aORs for current continuers and non‐continuer users of dabigatran were 1.36 (1.00–1.86) and 2.19 (1.61–2.98), respectively. For the latter, non‐continuer users with a short duration of dabigatran cumulated the highest risk (3.36 [1.88–5.99]). There also was an increased risk with concomitant use of tramadol and rivaroxaban (2.24 [1.19–4.21]), or antagonist of vitamin K (1.30 [1.00–1.69]).ConclusionThere was a trend towards and increased risk of excess bleeds when using concomitantly with dabigatran. The effect decreases with a narrower definition of current use.

Abstract‘Comrade’ (Reg. no. CV‐149, PI 698820) is a large‐seeded, high‐oleic, virginia‐type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) with enhanced pod size distribution and seed size compared with the virginia‐type cultivar ‘Contender’. Released jointly by the USDA‐ARS and North Carolina State University in 2021, Comrade (tested as N15022olEJ and NCEX17) is a high‐oleic virginia breeding line resulting from a selection made from the cross N06007E/3/X05248(BC1F1:F04), Bailey//X05027 (F01), Bailey/N02060ol. Comrade had an average pod yield of 5,260 kg ha–1, a total sound mature kernel (TSMK) of 69%, a sound mature kernel (SMK) weight of 97 g 100 seed–1, and 62% extra‐large kernels (ELKs), giving it the highest estimated value per hectare among the virginia‐type cultivars tested in Oklahoma for 2018–2020. When entered in the national Uniform Peanut Performance Test, Comrade performed well in all locations, averaging 5,235 kg ha–1, 84% fancy pods, 44% ELKs, an SMK weight of 103 g 100 seed–1, and a TSMK of 68%. Comrade's average super jumbo pod count per kilogram and average pod brightness score were reported at 317 kg–1 (9 per ounce) and 50, respectively, indicating large, bright pods, which are necessary components of any market‐worthy virginia‐type cultivar. Comrade consistently averaged 47–50% super jumbo pods across locations in Oklahoma and nationwide trials. This significant increase in the percentage of super‐jumbo pods compared with currently grown cultivars will increase growers’ profits and enable producers in the southwestern United States to increase participation in the foreign export market.
Investigating general and specific psychopathology factors with nuance‐level personality traits

Published: August 2022

AbstractMental health disorders share substantial variance, prompting researchers to develop structural models that can capture both generalised psychopathology risk and disorder/symptom‐specific variation. This study investigated the associations of the general and specific psychopathology factors with multiple personality trait hierarchy levels: broad domains, their facets and nuances (N = 1839 Estonian adults). A bi‐factor model with a general ‘p’ factor and specific factors for internalising problems, thought disorders and substance use best represented psychopathology structure. Although traits' predictive accuracy varied across psychopathology factors, nuances (the lowest level personality units) provided higher predictive accuracy and higher discriminant validity than domains. For example, traits related to high vulnerability, depression and immoderation and low friendliness and achievement striving were most strongly associated with the p factor. Nuances may prove useful for predicting and understanding general and specific psychopathology forms.
Functionalization of polyfluorene‐wrapped carbon nanotubes using thermally cleavable side‐chains
Authors: Ritaine Dialia , Adronov Alex 
Published: August 2022

AbstractThe length and nature of side‐chains in conjugated polymer‐wrapped carbon nanotubes can impact their conductivity. We investigate functionalization of polyfluorene‐single‐walled carbon nanotubes (SWNT's) using cleavable side‐chains that are removable post‐processing. The triethylene glycol side‐chains contain a thermally cleavable carbonate linker. Upon heating the films to 170 °C, the conductivity increased, reaching a plateau of (2.0 ± 0.1) × 10−2 S/m after 16 h, compared to (1.0 ± 0.2) × 10−3 S/m for the control sample. UV–Vis–near‐infrared (NIR) and Raman spectroscopy show well‐dispersed SWNT samples and confirm that the heating treatment did not damage the nanotubes. Functionalization using longer polyethylene glycol side‐chains was also investigated. After heating, cleavage of the longer chains resulted in conductivity of (8.2 ± 1.6) × 10−4 S/m compared to (8.1 ± 1.4) × 10−5 S/m for the control. UV–Vis–NIR and Raman spectroscopy showed well‐dispersed SWNT samples and confirmed that the nanotubes were not damaged. Finally, we investigate dispersions in triethylene glycol monomethyl ether and tetraethylene glycol dimethyl ether, generally deemed “green” solvents. Polymer‐SWNT complexes functionalized with shorter side‐chains did not form stable dispersions, resulting in precipitation of the nanotubes upon standing for a few minutes after the removal of tetrahydrofuran, while complexes functionalized with longer side‐chains formed stable dispersions.
Social determinants and health‐related quality of life in a sample of diverse, low socioeconomic status cancer patients

Published: August 2022

AbstractObjectivesIn the United States, medically underserved populations, such as ethnoracially underrepresented groups, the limited English proficient (LEP), and the unemployed, may be vulnerable to poor functioning in cancer survivorship. The present study examined whether race/ethnicity, LEP status, and unemployment status were associated with poor health‐related quality of life (HRQL) in four domains (physical, social, emotional, and functional well‐being (FWB)) in a diverse, low socioeconomic status (SES) sample of cancer patients.MethodsThe sample included 1592 ethnoracially diverse, low SES, primarily foreign‐born adult oncology patients participating in an enhanced patient navigation program in 11 New York City hospital‐based cancer clinics. This secondary cross‐sectional analysis of program intake data examined bivariate associations between sociodemographic and clinical factors and poor HRQL (Functional Assessment of Cancer Therapy‐General scores ≤70). Factors found to be related to poor HRQL (at p < 0.05) were entered into logistic regressions with overall HRQL and the four HRQL subscales as outcomes. The Benjamini‐Hochberg Procedure controlled for potentially inflated type‐I error rate due to multiple comparisons.ResultsAll three predictor variables (race/ethnicity, LEP status, and unemployment status) were significantly associated with increased odds of reporting poor FWB. Specifically, non‐Hispanic White and Hispanic cancer patients had 2.7 and 1.5 times the odds of reporting poor FWB than non‐Hispanic Black patients. The unemployed had 1.4 times the odds of reporting poor FWB than their employed or retired counterparts. Limited EP patients had 1.4 times the odds of reporting poor FWB than EP participants. Non‐Hispanic Black patients evidenced significantly lower odds of reporting poor HRQL across all subscale domains compared with other ethnoracial groups.ConclusionsLEP and unemployed individuals were more likely to report poor FWB, which may indicate that the most marginalized cancer patients face significant barriers to adequate functioning. Interventions that promote functional abilities (i.e., activities of daily living, self‐care, and work retention) and policies and programs that reduce systemic inequality and address social determinants of health may aid in improving HRQL for these underserved groups in survivorship. Non‐Hispanic Black cancer patients were less likely than other groups to report poor physical, social, emotional, and FWB. Identifying protective factors in this group may aid in efforts to improve HRQL for all patients.
Observer‐based adaptive sliding‐mode control under dynamic event‐triggered scheme with actuator and communication faults

Published: August 2022

AbstractThe adaptive technique and sliding‐mode algorithm (SMA) for observer‐based fault tolerant control is discussed with dynamic event‐triggered scheme (DETS) in this article. Both the actuator and communication faults are considered, which implies that the inputs of system and controller are unreliable. Moreover, the switched DETS for controller‐actuator channel is proposed to reduce bandwidth usage and actuator action frequency, which is different from the traditional event‐triggered strategies. To deal with communication faults, which can be described as packet losses, the closed‐loop system is modeled as a stochastic system. The SMA‐based observer is designed to estimate system states, which lays the foundation for the design of control algorithm to mitigate the effects of faults and DETS. Then, a novel observer‐based adaptive sliding‐mode control (SMC) law based on hyperbolic tangent function is proposed to guarantee the stochastic globally uniformly ultimately boundedness and reduce chattering. At last, the proposed DETS and observer‐based adaptive SMC law are applied into a robotic arm to illustrate the validity.
Renewable energy for sustainable development in Asia‐Pacific region: Do foreign direct investment and regulatory quality matter?
Authors: Annamalaisamy Bhuvaneskumar , Vepur Jayaraman Sivakumar 
Published: August 2022

AbstractGlobal climate change has already created noticeable ill‐effects on the environmental system and attaining further economic growth without compromising environmental quality is a difficult challenge for every country on this planet. Inspired by United Nation's Sustainable Development Goals (SDGs) core agenda, we investigated the singular, combined, and coupling influence of income growth, foreign direct investment inflows, renewable energy, and regulatory quality (RQ) on climate change under the scale, technique, and composition effects hypothesis. This analysis enables the creation of appropriate policy interventions to mitigate the severity of climate change in the future for the diverse countries in the Asia‐Pacific region. The study adopted the dynamic heterogenous estimation methodology responsible for accounting for the heterogeneity. We estimated 14 empirical models for the panel data from 1996 to 2015 of Asia‐Pacific countries. Empirical results validated the scale, technique, and composition effects and include that the progress in the share of renewable energy consumption in emerging countries by 1% reduces the greenhouse gas emissions by 0.24% (99% Confidence interval [C.I]), whereas 1% increase in the interactive effect of renewable energy and RQ deepens the emissions by 0.35% (99% C.I). The income level and RQ aggravate greenhouse gas emissions; whereas renewable energy diminishes the overall emissions level in emerging and advanced economies. This article's empirical outcomes would facilitate climate change mitigation‐related policy interventions of diverse economies in the Asia‐Pacific region to attain Sustainable Development Goals (SDGs‐ 7 and 13).
Can nuclear energy technology budgets pave the way for a transition toward low‐carbon economy: Insights from the United Kingdom
Authors: Caglar Abdullah Emre 
Published: August 2022

AbstractThe energy resources of the economies play a critical role in reaching the 2030 and 2050 decarbonization targets. In this respect, research and development budgets for nuclear energy (NRD), which constitutes one‐fifth of the current energy resources in the United Kingdom, can be a step in the transition to a low‐carbon economy. However, the current literature neglects the impact of NRD on environmental quality for the United Kingdom. Thus, this paper explores the impact of NRD on CO2 in the United Kingdom by controlling income, trade openness, and financial development from 1974 to 2020 with a non‐linear autoregressive distributed lag (NARDL) approach. Empirical findings confirm the asymmetrical relationship between NRD and CO2. In this context, while positive changes in NRD reduce environmental degradation, negative changes in NRD hinder environmental sustainability. Another finding is that the environmental Kuznets curve (EKC) hypothesis is valid. Furthermore, the results show that while economic growth and trade openness reduce environmental quality, financial development contributes to environmental quality. Considering these findings, financial deepening activities should continue in the United Kingdom. More resources should be allocated to nuclear energy research and development budgets in the transition to a low‐carbon economy.
The determinants and performance outcome of the firm's capacity to maintain customer loyalty
Authors: Ullah Zeeshan 
Published: August 2022

AbstractThis research aims to study the determinants and performance‐outcome of the firm's capacity to maintain a loyal customer base. Therefore, this research investigates the influence of sustainable product development on the firm's capacity to maintain customer loyalty. Furthermore, this research investigates the moderating influence of marketing resource intensity on sustainable product development and the firm's capacity to maintain customer loyalty. Moreover, this research investigates the firm profitability as a performance outcome of the firm's capacity to maintain customer loyalty. This research uses the panel dataset of 433 manufacturing firms from the United States. The findings from fixed‐effect regression analysis confirm the significant positive influence of sustainable product development on the firm's capacity to maintain customer loyalty. The moderation analysis confirms the significant positive influence of marketing resource intensity on sustainable product development and the firm's capacity to maintain customer loyalty. The results also confirm the contribution of the firm's capacity to maintain customer loyalty to firm profitability. This study contributes to the customer loyalty literature stream by theorizing the capacity to maintain customer loyalty construct and empirically studying its performance outcome, the contribution of sustainable product development in the firm's capacity to maintain customer loyalty and the moderating role of marketing resource intensity in this regard, under the resource‐based view. Based on the study findings, this research suggests that managers need to emphasize sustainable product development in the firms to strengthen the firm's capacity to maintain customer loyalty and recognize the interactional role of marketing resource intensity in this regard.
Decentralized trade finance using blockchain and lightning network
Authors: Kumar Shivansh , Amin Ruhul 
Published: August 2022

AbstractA decentralized trade finance system is urgently needed, as smart contracts and blockchain can make the entire process fast, secure, and efficient while also allowing ordinary people to participate in the global economy. Decentralization will increase trust and transparency, as well as allow smaller businesses to participate in the industry, resulting in more jobs and a boost to the economy. We have also taken a decentralized approach to solving this massive problem with our project. We propose a decentralized trade finance model that is owned by the general public, such as you and me. On the one hand, a community of people like you and me give liquidity to the platform's liquidity pool via a lighting network, while on the other hand, importers and exporters can create profiles and engage in trade finance via the decentralized network. The exporter will use the platform validator to validate their invoice and then apply for trade finance. If everything goes well, the exporter will get monies from the liquidity pool, and the platform will be compensated by the importer after the trade is completed. Everyone involved in the process will receive trade tokens when each successful deal is completed, incentivizing the participants' good behavior.
Experimental study on mechanical properties of steel and steel fiber reinforced concrete beams
Authors: Wu Kai , Zhang Yanjie , Lin Shiqi , Liang Qingqing , Qian Shiyuan 
Published: August 2022

SummaryAccording to the construction difficulties in steel reinforced concrete (SRC) structures, rebar cages were discretized into steel fibers to form steel and steel fiber reinforced concrete (SSFRC) structures. The 18 SSFRC beams without rebar cages were tested under bending, and the effect of the steel fiber volume ratio (ρsf), shaped steel ratio (ρss), and shear span ratio (λ) on mechanical properties were investigated. Increasing ρsf could not only turn shearing failure and debonding failure into bending failure, and effectively reduce the sudden decrease of load, but also enhance the bearing capacity, ductility, and damage resistance of specimens to a certain extent. As the ρss ascended, the mechanical properties were obviously improved. However, ρsf should be accordingly increased to avoid adverse effects of excessive ρss. The specimen with small λ had the better bearing and energy dissipation capacity and poor ductility. A large λ meant that ρss and ρsf should be appropriately increased to prevent premature failure of specimens.
High school students' out‐of‐school science participation: A latent class analysis and unique associations with science aspirations and achievement

Published: August 2022

AbstractStudents' out‐of‐school science participation has been identified as a factor that supports adaptive science outcomes. Researchers have largely investigated students' out‐of‐school science participation in terms of structured science activities (e.g., attending a science camp), with far less consideration of how students' involvement in unstructured out‐of‐school science activities (e.g., using at‐home science kits) may also be associated with students' aspirations and achievement in science. Research in this area has established a conceptual framework by which activities can be categorized by the activity's level of interaction (i.e., whether receptive or active). Although this conceptual framework is useful to understand the types of unstructured activities in which students engage, this research has tended to overlook the fact that students often participate in more than one out‐of‐school unstructured activity. The present investigation addressed this dearth of research by examining the extent to which different typologies of student participation in out‐of‐school receptive and active unstructured activities existed. The study also examined if these profiles were uniquely associated with students' aspirations and achievement in science above and beyond the effects of their current level of in‐school participation. The study employed a latent class analysis of N = 996 Australian high school students (40.60% girls) from six schools serving predominately above average socioeconomic status Australian high school students. Four distinct profiles of out‐of‐school participation in unstructured activities were found: Optimal, Receptive, Active, and Minimal Out‐of‐School Participation (OSP). The Optimal OSP and Receptive OSP profiles were associated with the higher aspirations (beyond students' in‐school participation), and both were significantly higher than the Active OSP and Minimal OSP profiles. Students' in‐school participation was most strongly associated with students' achievement. These findings suggest that encouraging students' participation in unstructured activities, especially receptive unstructured activities, and their in‐school participation may be viable avenues by which to improve students' science aspirations and achievement.
