Authors: M Sathesh Babu , R Ramamoorthi , S Gokulkumar , K Manickaraj 
Published: October 2024

AbstractThis study aimed to evaluate the effect of incorporating Mahua oil cake microcellulose (MOCM) on the mechanical and sound absorption properties of flax fiber‐reinforced polymer composites fabricated using the compression molding technique. X‐ray diffraction (XRD) analysis revealed that MOCM had a crystallite size (Cs) of 6.71 nm and a crystallinity index (CI) of 63.25%, indicating its potential for mechanical reinforcement. Thermogravimetric analysis (TGA) demonstrated that MOCM exhibits thermal stability up to 355.44°C, which is suitable for high‐temperature applications. Mechanical testing revealed that the incorporating 7.5 wt.% MOCM into flax fiber composites achieved optimal results, with the tensile strength reaching 70.23 MPa, flexural strength peaking at 113.23 MPa, and impact strength at 33.4 kJ/m2. Scanning electron microscopy (SEM) analysis confirmed the improved interfacial bonding between the fibers and matrix, contributing to enhanced mechanical performance. The noise reduction coefficient (NRC) and sound absorption coefficient (SAC) also improved with increasing MOCM content, with the highest SAC (0.328) and NRC (0.312) values observed at 10 wt.% MOCM. These findings suggest that MOCM enhances both the mechanical and acoustic properties of flax fiber composites, making it a promising material for applications in the automotive, aerospace, and construction industries, where both structural integrity and sound absorption are critical.Highlights

Published: October 2024

AbstractIn this study, microcapsule‐based jute fiber reinforced epoxy self‐healing composites were fabricated using the vacuum bagging technique. Water‐soluble epoxy microcapsules were synthesized by the in‐situ polymerization method. Scanning electron microscopic (SEM) analysis showed that the substantial microcapsule size varies from 3 to 15 μm. Microcapsule of 3 wt.% amount was incorporated in the sample. Healing capability of the composite was assessed via impact strength recovery. Incorporating microcapsules within the cracked surface of the composite facilitated healing, demonstrating notable improvements in efficiency. Results indicated that the epoxy composite healed from a 1 mm deep crack exhibited higher impact strength recovery than samples healed from a 1.5 mm deep crack, with healing efficiencies of 83.9% and 78.89%, respectively. Fourier transform infrared spectroscopy spectra and energy dispersive x‐ray of the sample confirmed the presence of relevant chemical groups in both microcapsules and the composite. In thermogravimetric analysis, it is found a mass loss of 10.3% during the initial stage of decomposition, occurring between 180 and 250°C following the final phase of thermal degradation upto 500°C.Highlights

Published: October 2024

AbstractA brief self‐reported measure of the Personality Assessment Questionnaire for the 11th edition of the World Health Organization's International Classification of Disease (ICD‐11) (PAQ‐11) was developed to evaluate ICD‐11 personality traits. The aim of this study was to investigate the validity of the revised PAQ‐11 version (PAQ‐11R) with an additional item in the Dissociality domain and thresholds for the severity of personality dysfunction and domains. Study 1 examined the construct validity of the PAQ‐11R in 192 university students in Korea. Study 2 estimated tentative reference scores of personality dysfunction and domains of the PAQ‐11R in 91 patients in Korea. In study 1, the PAQ‐11R had a five‐factor structure and the revised Dissociality scale had better convergent and discriminant validities than the previous version. In study 2, the receiver operating characteristic (ROC) curve of the PAQ‐11R identified a threshold score of 35. Reference scores for domains were estimated as 15 for Negative Affectivity, 10 for Detachment, 8 for Anankastia, and 5 each for Disinhibition and Dissociality. These scores contribute to severity of personality disturbance but remain qualifiers only; they are not diagnostic. The results suggest that the PAQ‐11R is useful as a quick assessment tool for identifying the domains of personality dysfunction in clinical practice in harmony with the ICD‐11 guidelines.
From multistakeholderism to digital sovereignty: Toward a new discursive order in internet governance?
Authors: Pohle Julia , Santaniello Mauro 
Published: October 2024

AbstractSince the early 2000s, the multistakeholder governance approach has been the reference model for transnational internet governance, reaching far beyond the original field of technical coordination and standard‐setting. But over the last decade many countries, including democracies supportive of multistakeholderism, have adopted measures to strengthen their digital sovereignty. Thereby, they have been advancing discourses and practices that reinforce state power with regard to the digital and are often at odds with the multistakeholder model. This paper analyzes the emerging dialectic between multistakeholder internet governance and digital sovereignty by seeking to understand how the pursuit of digital sovereignty is increasingly challenging the hegemony of the multistakeholder discourse in internet governance. To this purpose, it reassesses the historical development of power struggles over the internet through the analytical lenses of the discourse coalition framework. After reconstructing how the multistakeholder discourse has emerged and institutionalized in the internet governance arena, the paper retraces the expansion of the digital sovereignty discourse, regarding both the actors promoting it and the narratives attached to it. It also identifies key motivations behind this discourse. Finally, the paper discusses whether the digital sovereignty discourse is emerging as a new discursive order in the internet governance field and draws attention to conditions that could either support or weaken its emergence.

Published: October 2024

ABSTRACTBoth Layered Double Hydroxide (LDH) and MXene are two‐dimensional layered materials recognized for their remarkable flame‐retardant properties. Combining these materials enhances the fabrication of high‐performance flame retardants. In this work, a ternary CoFeCr‐LDH@MXene hybrid material was synthesized via a facile hydrothermal method, effectively mitigating heat release, smoke generation, and toxic gas emissions during the combustion of Thermoplastic Polyurethane (TPU). Compared to pristine TPU, the composite material TPU/2wt%CoFeCr‐LDH@MXene demonstrated reductions in peak heat release rate (pHRR) by 39.4%, total heat release (THR) by 28.3%, peak smoke production rate (pSPR) by 61.1%, total smoke production (TSP) by 31.3%, and peak carbon monoxide release rate (pCO) by 56.7%. The study revealed that the CoFeCr‐LDH@MXene hybrid not only catalyzes the formation of a high‐quality char layer but also facilitates the conversion of harmful gases into CO2. This research provides insights into the development of efficient ternary LDH@MXene flame retardants and TPU composites with significantly enhanced fire safety.

ABSTRACTObjectiveThis study examines the association between psychosocial risk and protective factors and a wide range of psychosocial outcomes including emotional, social, cognitive, and physical domains in childhood cancer survivors (CCS).MethodsCCS from the Dutch Childhood Cancer Survivor Study (DCCSS)‐LATER cohort (diagnosed 1963–2001) part 2 (age ≥ 18 years, diagnosed < 18 years, ≥ 5 years since diagnosis) completed questionnaires on psychosocial risk and protective factors (Benefit and Burden Scale, Illness Cognition Questionnaire, Rosenberg Self‐Esteem Scale, and Impact of Cancer Scale), and psychosocial outcomes (Hospital Anxiety and Depression Scale, Self‐Rating Scale for Post‐Traumatic Stress Disorder, TNO‐AZL Questionnaire for Adult Health‐Related Quality of Life, and Short Form‐36). Associations were assessed with regression analysis, adjusting for attained age, sex, number of health conditions, and time since diagnosis, while correcting for multiple testing (p < 0.004).ResultsA total of 1382 CCS participated, all diagnosed ≥ 15 years ago. The mean age of participating CCS was 36 years, and 51% were female. Perceived benefit and burden, acceptance, and helplessness, self‐esteem and social support were associated with the psychosocial outcomes. In the models including all psychosocial factors, most associations with psychosocial outcomes were seen for self‐esteem (10×), and perceived burden (9×). Self‐esteem (all β ≤ 0.47) and perceived burden (all β ≤ 0.38) demonstrated strongest associations of medium/large size.ConclusionsPerceptions of childhood cancer, illness cognitions, self‐esteem, and social support play a role in explaining psychosocial functioning in CCS, outweighing the influence of socio‐demographic and medical variables. Addressing negative perceptions and reducing feelings of helplessness, while promoting acceptance, self‐esteem, and social support, could provide intervention targets for CCS who encounter psychosocial challenges.
Long‐term respiratory consequences of prematurity
Authors: Pijnenburg Mariëlle W 
Published: October 2024

AbstractApproximately 10% of all children worldwide are born preterm and respiratory consequences are amongst the most common sequelae of preterm birth. Except for a higher prevalence of respiratory symptoms and hospital admissions, preterm birth is associated with lower lung function that may track into adulthood. Lung function impairment is not restricted to extreme or very preterm‐born subjects as also children born moderate‐late preterm have lower Z‐scores for lung function. Given the heterogeneity of prematurity‐associated lung disease, phenotype‐based, multidisciplinary management is needed to improve respiratory health in preterm‐born subjects.

AbstractBACKGROUNDInvasive ungulates (hoofed mammals), including deer, feral pigs, feral goats, and feral sheep, are known to cause damage to agriculture, property, natural resources, and many other commodities. Most of the information regarding the economic impacts of wild ungulates is from North America, where some of these species are native. To evaluate invasive ungulate damage to livestock producers in the Hawaiian Islands, which have no native ungulates, a survey was distributed to livestock producers across the state.RESULTSSurvey results described how total annual costs are distributed among damage, control, and repairs for survey respondents, who represented a significant percentage of total ranchland acreage across the islands. The estimates, excluding fixed fence installation, revealed an annual cost to livestock producers who responded to the survey of US$1.42 million, which ranged from $3.6 million to $7.5 million when extrapolated to the entire state. The large cost contributors included damage to property, pastureland repair, control costs (excluding fencing), supplemental feed, and predation of calves by wild pigs. Additionally, producers reported spending more than $2 million in upfront fence installation costs. Most of these costs were reported by respondents on the islands of Hawai'i and Moloka'i.CONCLUSIONStudy results revealed substantial damage to state livestock producers due to wild ungulates and are useful in determining an invasive ungulate management strategy that can appropriately aid the most impacted sectors of Hawai'i. © 2024 The Author(s).

Interactions between prosulfocarb and trifluralin metabolism in annual ryegrass (Lolium rigidum)
Authors: Goggin Danica E , Cawthray Gregory R , Busi Roberto 
Published: October 2024

AbstractBACKGROUNDCross‐resistance between pre‐emergence herbicides is developing in Australian populations of annual ryegrass (Lolium rigidum Gaud.). A previous study has reported that selection with prosulfocarb (a pro‐herbicide requiring bioactivation to its phytotoxic sulfoxide) can decrease metabolic resistance to trifluralin. Metabolism of prosulfocarb and trifluralin was investigated in L. rigidum populations with different levels of resistance to prosulfocarb, trifluralin and also pyroxasulfone, which is detoxified by glutathione (GSH) conjugation.RESULTSColeoptiles and radicles of herbicide‐treated seedlings responded differently to the same herbicide. Radicles had a lower capacity for bioactivation of prosulfocarb, and this was correlated with a lower ability to metabolise trifluralin within and among populations. Coleoptile resistance to prosulfocarb sulfoxide was negatively correlated with abundance of a major polar metabolite. There was no evidence of GSH conjugation with the sulfoxide, making any potential links between prosulfocarb and pyroxasulfone resistance less obvious.CONCLUSIONSActivation and metabolism of prosulfocarb in L. rigidum is complex and differentially regulated in different tissues. Selection with prosulfocarb may ameliorate trifluralin metabolism in the radicles, but the relationship between prosulfocarb and pyroxasulfone resistance is not GSH‐mediated. When applying pre‐emergence herbicides, care should be taken with the composition of mixtures and rotations to avoid selection of cross‐resistance between pyroxasulfone and prosulfocarb. © 2024 The Author(s).

A bivariate dependent degradation model based on artificial neural network supported stochastic process and Copula function
Authors: Liu Di , Duan Xiaochuan , Wang Shaoping , Shi Jian , Shang Yaoxing 
Published: October 2024

AbstractIn order to use the high ability of the artificial neural network (ANN) in data fitting, this paper introduces an ANN in stochastic process to describe the mean function for degradation modeling. Due to the fact that the existing method cannot handle the bivariate dependent degradation conditions, a bivariate dependent degradation model based on Copula function and ANN‐supported stochastic processes is proposed. Considering the random effects caused by individual difference, it is assumed that the unknown parameters in the stochastic processes and Copula functions are randomly distributed. Based on the maximum likelihood and moment estimation methods, a related statistical inference method for ANN training and parameter estimation is developed to use the bivariate dependent degradation model. An actual fatigue crack dataset is used to demonstrate the validity of the proposed method. The obtained results show that the dependent relationship between two degradation indicators should not be neglected, and it can be efficiently handled by the proposed method. Furthermore, the proposed degradation model can provide reliability and degradation intervals with enough precision due to the fact that it considers the random effects caused by individual difference.
Consecutive time‐intervals‐dependent looped functionals for stability analysis of linear systems with asynchronous sampling
Authors: Park JunMin , Lee Seok Young 
Published: October 2024

AbstractThe purpose of this article is to propose a novel framework employing a looped‐functional approach for the stability analysis of continuous‐time linear systems with asynchronous sampling. In this approach, a negative forward‐difference of a Lyapunov functional consisting of a Lyapunov function and a looped‐functional sufficiently guarantees asymptotic stability of the sampled‐data systems. To reduce the conservatism of the stability criteria, we develop a consecutive time‐intervals‐dependent looped‐functional approach that satisfies a convex looping inequality with respect to each sampling interval. Compared to the existing looped‐functional approaches, the proposed method provides a more general looped‐functional and in turn a more relaxed stability conditions. The existing looped functionals and their associated looping conditions can be considered as special cases of the proposed ones. This relationship can easily be verified by excluding time‐intervals‐dependent terms in the general looped functional. Four numerical examples that consider both periodic and asynchronous sampling cases demonstrate that the proposed looped‐functional approach shows better performance in terms of allowable maximum sampling intervals at a cost of a small additional number of decision variables.
The rank of sparse symmetric matrices over arbitrary fields

Published: October 2024

AbstractLet be an arbitrary field and be a sequence of sparse weighted Erdős–Rényi random graphs on vertices with edge probability , where weights from are assigned to the edges according to a matrix . We show that the normalized rank of the adjacency matrix of converges to a constant, and derive the limiting expression. Our result shows that for the general class of sparse symmetric matrices under consideration, the asymptotics of the normalized rank are independent of the edge weights and even the field, in the sense that the limiting constant for the general case coincides with the one previously established for adjacency matrices of sparse nonweighted Erdős–Rényi matrices over . Our proof, which is purely combinatorial in its nature, is based on an intricate extension of a novel perturbation approach to the symmetric setting.

Abstract

Background
Cutaneous melanoma (CM) and non-melanoma skin cancer (NMSC) are rising in postmenopausal women. Although high doses of oral vitamin A reduce NMSC risk in high-risk patients, the role of vitamin A in preventing skin cancer in this group remains unexplored.

Objectives
To determine the association between total (dietary and supplemental) vitamin A and risk of CM and NMSC in postmenopausal women.

Methods
This retrospective cohort study included 52 877 White women from the Women's Health Initiative cohort, spanning from 1993 to 2019. Exposures were intake of total vitamin A, retinol and provitamin A carotenoids. Cox proportional hazard models estimated hazard ratios for overall CM incidence, whereas logistic regression determined odds ratios (ORs) for melanoma subtypes and NMSC.

Results
1154 cases of CM and 9085 cases of NMSC were identified over an average follow-up period of 17.8 years (SD 6.7). No associations were identified between total vitamin A intake and melanoma risk. Higher dietary vitamin A intake was associated with higher risk of NMSC (OR of 3rd vs. 1st tertile of dietary intake = 1.12, 95% confidence interval [CI] [1.06, 1.18]), as was dietary beta-cryptoxanthin, a provitamin A carotenoid (OR of 3rd vs. 1st tertile of dietary intake = 1.22, 95% CI [1.15, 1.29]); these results were consistent across both age- and fully adjusted regression models.

Conclusions
Total vitamin A intake was not associated with lower risk of CM or NMSC. Dietary vitamin A and beta-cryptoxanthin intake were associated with a slightly higher risk of NMSC in postmenopausal women.
Development of a Water‐Based Pressure‐Sensitive Adhesive via Emulsion Polymerization for Packaging Tape Applications
Authors: Kiral Çelik Nahide , Gürmen Tuğba 
Published: October 2024

AbstractIn this study, water‐based pressure‐sensitive adhesives (PSAs) were synthesized through an emulsion polymerization process using n‐butyl acrylate, methacrylic acid, acrylic acid, and N‐vinylpyrrolidone monomers, in combination with anionic and non‐ionic surfactants. The PSA was coated onto the corona‐treated surface of a BOPP film using a Mayer bar to prepare packaging tape. The effect of surfactant concentration on the properties of the resulting copolymer and PSA was investigated. The chemical structure, component distribution, and thermal behavior of the copolymer were analyzed using FTIR, HPLC, and DSC. The physical properties of the synthesized copolymer, such as solid content, viscosity, particle size, and gel content, were also determined. The performance of the prepared packaging tapes was evaluated through loop tack, 180° peel, and holding shear time tests. The results indicated that surfactant concentration significantly affected the adhesive's performance. Notably, the use of a 2.5 wt% surfactant mixture yielded promising results, with high monomer conversions and excellent adhesion properties in the tape.
