Published: December 2023

SummarySoftware defined networking is a modern paradigm that divides the control plane from the data plane for improved network manageability. A flow table in the data plane has limited and expensive memory called TCAM. The presence of unwanted flow rules would lead to flow bloat conditions and make the lookup operation inefficient. Eviction schemes based on LRU policy have been widely studied in the literature which preempts the life of the least recently used flow rule and reduces the occupancy of the flow table. LRU considers the past behavior for the eviction of a flow rule. This paper proposes a novel policy that preempts a flow rule by considering its future characteristic, the shortest remaining time (SRT). A rule with a higher probability of being used is avoided from eviction to mitigate the degradation of performance. The modeling of the SRT technique exhibits better utilization of a flow rule that has higher probability of being used. On the other hand, LRU does not guarantee that the evicted flow rule will not be used frequently in the future and it has been shown that an incorrectly evicted flow rule incurs controller delay. The experimental results show that for different traffic rates, SRT has reduced the delay by 15%, reinstallation count by 25%, and jitter by 40%. SRT has increased utilization by 22% compared to LRU.

AbstractAimTo elucidate the meaning of being a close relative of a critically ill person cared for in intensive care during the initial phase of the COVID‐19 pandemic.DesignA narrative inquiry design following the COREQ guidelines.MethodsIndividual interviews with fifteen close relatives of patients critically ill with COVID‐19 were analysed using phenomenological hermeneutics.ResultsThe surreal existence of not being allowed to be near was emotionally difficult. While distancing due to restrictions was challenging, physicians' phone calls served as a connection to their relatives and brought a sense of security. Keeping notes helped them remember what happened and brought order to a chaotic situation.ConclusionClose relatives feel secure when they receive regular information about their critically ill relative, not just when their condition worsens. They wish to be physically near to their critically ill person; when this is impossible, digital technology can provide support, but further accessibility developments are needed.

AbstractAimTo compare knowledge of Nursing Degree students about Best Practice Guidelines when there are included as teaching content in a subject vs knowledge through having the usual internship experience without teaching specific guidelines contents.DesignNon‐randomized post‐test‐only design with a comparison group.Methods143 students of the nursing degree at the Autonomous University of Barcelona were recruited. The intervention group received a classroom training in three Best Practice Guidelines with Problem‐Based Learning methodology. The comparison group only attended internship, without specific guidelines contents. Knowledge was evaluated with an ad hoc post intervention questionnaire. The information was collected between 2016 and 2018.ResultsThe average score of knowledge was low, 5.1 out of 10, and differs between guides. The best results were obtained by the students with internships and that had consulted the guides on some occasions. Synchronized effort and leadership in Academia and Healthcare are needed to favour evidence‐based practice. The combination of the consultation of the Best Practice Guidelines in theoretical learning combined with the practice, increases the knowledge of the Best Practice Guidelines and will favour the implementation of evidence‐based practice. Some students were involved in questionnaire design.

AbstractObjectiveTo describe iatrogenic laryngeal injury and identify its risk factors in recurrent respiratory papillomatosis (RRP) patients receiving surgical care.Study DesignCase‐control.SettingTertiary care academic hospital in a metropolitan area.MethodsCharts of patients with RRP seen at our institution from January 2002 to December 2022 were reviewed. Patients were separated into 2 cohorts based upon whether they experienced any form of iatrogenic laryngeal injury—including anterior commissure synechiae, vocal cord scar, reduced vocal fold pliability, vocal fold motion impairment, and glottic and/or subglottic stenosis. Adjusted logistic regressions were performed to identify factors associated with iatrogenic laryngeal injury.ResultsOf 199 RRP patients, 133 (66.8%) had identifiable iatrogenic laryngeal injury. The most common injuries were anterior commissure synechiae (n = 67; 50.4%) and reduced vocal fold pliability (n = 54; 40.6%). On a multivariate logistic regression, patients with diabetes mellitus (adjusted odds ratio [aOR] [95% confidence interval [CI]]: 2.99 [1.02, 8.79]; P = .04) and who received at least 10 surgeries lifetime (aOR [95% CI]: 14.47 [1.70, 123.19]; P = .01) were at increased risk for iatrogenic laryngeal injury, whereas receiving less than 5 surgeries (aOR [95% CI]: 0.21 [0.09, 0.51]; P < .001) was found to be protective. When treating the lifetime number of surgeries as a continuous variable, a greater number of surgeries was a significant risk factor for iatrogenic laryngeal injury (aOR [95% CI]: 1.32 [1.14, 1.53]; P < .001).ConclusionThese results suggest the importance of strict glucose control for diabetic patients receiving RRP surgical care, and emphasize the clinical need to identify medical therapies to decrease RRP surgical frequency for patients.

AbstractOutdoor recreation is an essential way many people engage with nature. The provision of public spaces for recreation intersects with conservation practices motivated by intertwined social and ecological values, such as strict practices associated with the concept of ‘wilderness’. Debates persist about how such concepts and management practices influence people's recreation experiences.Many US public land management agencies facilitate opportunities for outdoor recreation, relying on management frameworks and tools intended to foster specific experiential qualities. But these frameworks and tools assume simplistic relationships between settings and people's experiences, and managers rarely assess these relationships.This study uses a data set of nearly 70,000 crowdsourced trip reports from a hiking website to understand the qualities of visitors' experiences on trails. We study the geographic distribution of experiential qualities commonly associated with US wilderness areas: aesthetics, awe, challenge, pristineness, quietness, solitude and timelessness. Using analytical methods that rely on machine learning and natural language processing, we identify these experiential qualities in trip reports from hundreds of routes, and use generalized linear models to analyse relationships between the frequency of each experiential quality and the route's administrative, built, biophysical, geographic and social settings.We find that four of the seven experiential qualities (aesthetics, awe, challenge and solitude) are commonly described in trip reports, each appearing in 15%–55% of manually coded reports. The extent to which setting characteristics explained variability in experiences differed, ranging from 34% of the variability in the proportion of trip reports describing aesthetics to 55% for awe. The setting characteristics associated with each experiential quality also differed, with characteristics such as trail mileage and summit destinations having stronger influences on experiential qualities than characteristics such as wilderness designation.Synthesis and applications. Our findings suggest the need to consider more diverse variables in experience–setting relationships, develop more robust models to characterize those relationships and create new data sources to represent understudied variables. These advances would help empirically inform and improve frameworks and tools used for recreation and wilderness planning and monitoring, and potentially promote more responsive management to evolving social–ecological values.Read the freePlain Language Summaryfor this article on the Journal blog.

Published: December 2023

AbstractWith the rapid development of industry, water pollution caused by lead has caused great harm to human health. In this study, alginate is used as a base and blended with biochar to form calcium alginate hydrogel beads with high mechanical properties through ionic cross‐linking. Besides, the material (BC/MCAC) is prepared by the material (C‐γ‐Fe2O3) as a magnetizing agent and to remove lead. Then, a series of batch experiments and material characterizations are performed to evaluate the adsorption process of the material. The results show that the maximum adsorption capacity of BC/MCAC to Pb(II) is 211.6 mg g−1 at pH = 7. The adsorption process is well described by the Langmuir adsorption isotherm and pseudo‐second‐order kinetic model. This indicates that the lead adsorbed by BC/MCAC is a monolayer chemisorption that occurs on a uniform surface. After three regeneration cycles, BC/MCAC is found to retain 82.37% of the lead adsorption capacity and has good regeneration ability. Lead is removed by BC/MCAC mainly through the complexation of oxygen‐containing functional groups, electrostatic interaction, and ion exchange. BC/MCAC allows for more sustainable use of the wastes and is expected to be a new type of lead adsorbent for industrial wastewater.
A novel saturated PID‐type observer‐based controller for wheeled mobile robots with a guaranteed performance considering path curvature
Authors: Shojaei Khoshnam 
Published: December 2023

AbstractThis article proposes a novel saturated PID‐type formation controller for a class of nonholonomic wheeled mobile robots (WMRs) of type (m, s) with mobility m and steerability s. Since the path curvature causes a severe deviation of the followers from the leaders' trajectory in the corners, a new definition of output equations is suggested to construct the coordinates of a virtual reference point in the front of each follower based on the concept of the extended look‐ahead control that utilizes a corrective angle to compensate the trajectory curvature efficiently. A nonlinear transformation and the robot's kinematic and dynamic equations are heuristically combined to develop a novel second‐order Euler–Lagrange formulation of unconstrained errors from constrained errors. Then, a novel saturated PID‐type controller is proposed for WMRs to build a desirable formation with a prescribed performance. An innovative nonlinear observer is presented to estimate followers' velocities. An efficient mixture of a radial basis function neural network (RBFNN) and an adaptive mechanism is proposed to compensate for model uncertainties, external disturbances, and network approximation errors. Lyapunov's direct method verifies semi‐global uniform ultimate boundedness stability by estimating a gain‐dependent region of attraction. Numerical simulations finally show the efficiency of the proposed controller.
Consumers' perceptions of partnering brands: The roles of perceived sustainable development goals and partnership authenticity in a cross‐national context
Authors: Lorgnier Nicolas G. A. , Chanavat Nicolas , Su Che‐Jen , Cinar Kevser 
Published: December 2023

AbstractThis paper explores the ways in which consumers' perceptions of brands' sustainable development goals (SDGs) may influence perceptions of partnership authenticity and consumer loyalty toward partnering brands. Data collected from American, French, Turkish, Chinese, and Taiwanese respondents (n = 1241) were used to study the relationships among a Mega Sport Event Organizer – the International Olympic Committee, one of its sponsors, Airbnb, and their consumers. Findings reveal that both the salience of the partners' SDGs and the degree to which their SDGs align significantly impact the partnership authenticity which, in turn, fosters brand loyalty. Salience of brands' SDGs yields stronger predictions of partnership authenticity compared to SDG‐congruity. Additionally, while collectivism strengthens the effect of partnership authenticity, its impact on sustainable development is comparatively limited. From a conceptual standpoint, the research's contributions to categorization theory are discussed. Practical implications are presented for marketers seeking to enhance the effectiveness of their sustainable development strategy.

Published: December 2023

AbstractUsing halloysite as a natural support and palladium and rhodium salts, one bimetallic and two monometallic catalysts were prepared through wet‐impregnation method. The catalysts were characterized via TGA, XRD, FTIR, EDS and elemental mapping analyses and their activity for hydrogenation of poly‐alpha‐olefin oil was examined and compared. The results indicated that among the three catalysts, halloysite supported Pd nanoparticles and bimetallic halloysite supported Pd−Rh catalyst exhibited the highest and lowest activity, respectively. To clarify the origin of the observed difference in the activity of the catalyst, they have been further characterized via ICP and TEM analyses. The result indicated that the nature of the metallic species affected the loading and dispersion of the formed metallic nanoparticles. In the case of halloysite supported Pd nanoparticles, while metal loading was the highest, the formed particles were fine and well‐dispersed. It is whilst that in the case of bimetallic catalyst aggregation of particles was observed which was correlated to its lower efficiency. Optimization of the reaction variables via response surface methodology was also conducted using Pd/HNT catalyst. It was shown that using 5 wt.% catalyst at 130 °C under H2 gas with pressure of 8 bar, hydrogenation led to 97 % yield in 7 h. The catalyst was also reusable for 6 consecutive runs with negligible loss of activity.

Published: December 2023

AbstractPhlomis species have traditionally been employed for the treatment of a number of ailments such as influenza, the common cold, asthma, bronchitis, coughs, hemorrhoids, ulcers, and gastrointestinal disorders. The goal of this study is to compare the anti‐diabetic, anti‐glaucoma, and anti‐Alzheimer's properties and antioxidant activities of methanol (MEPT) and aqueous (WEPT) extracts from the aerial part of P. tuberosa L. Tandem mass spectrometry and liquid chromatography (LC–MS/MS) were used to investigate the compounds of MEPT and WEPT. The inhibitory effects of MEPT and WEPT on the enzymes acetylcholinesterase (AChE), carbonic anhydrase II (CA II) and α‐glycosidase were investigated and molecular docking studies demonstrated binding interactions between the major compounds chlorogenic acid, cyanidin‐3‐O‐glycoside, quinic acid, rosmarinic acid with AChE, CA II and α‐glycosidase enzymes. In addition to that, the total content of phenols and flavonoids was analyzed. Furthermore, the antioxidant activity was evaluated by DPPH, ABTS, DMPD, ferrous ions (Fe2+) chelating, FRAP, CUPRAC, and ferric ions (Fe3+) reducing methods. This study is the first of its kind to show that MEPT and WEPT possess inhibitory effects on AChE, CA II and α‐glycosidase, as well as displaying antioxidant properties.

Published: December 2023

AbstractChrysin, the natural bioactive flavone compound, has been identified in several edible materials such as honey, propolis, and passionflower with numerous biological potentials and pharmaceutical effects including antitumor, anti‐inflammatory, antiviral and antioxidant. The compound has been reported to have lower in vitro antioxidant activity compared to other flavone‐based structures such as quercetin, luteolin, and myricetin, which is mostly attributed to the higher hydroxylation and the presence of conjugated en‐diol structures in these flavonoids and the lack of these structural features in chrysin. On the contrary to the in vitro antioxidant effect of chrysin, the compound has exerted remarkable in vivo antioxidant activities in several models related to the liver, brain, heart, kidneys, and other soft tissues. The current review includes a discussion of the in vivo and in vitro antioxidant activity of chrysin compared to other common flavonoids. The study also covers subjects linked to chrysin antioxidants, such as its metabolism, bioavailability, and current formulations that aim to increase chrysin antioxidant impact and overcome its low bioavailability.

AbstractPhase change materials (PCMs) have been widely recognized as efficient solutions for thermal management across various industries, including logistics, construction, electronics, and others. Nevertheless, these materials encounter challenges such as leakage, poor thermal conductivity, and supercooling. To address these challenges, a comprehensive examination was conducted on the recent advancements pertaining to silicon‐based materials. These studies include their application as high temperature PCMs, as encapsulation matrices, and their integration as additives to enhance material properties. Aluminum–silicon (Al−Si) alloys offer a viable thermal management solution for high‐temperature applications, such as those found in car batteries. Silicon dioxide (SiO2), silicon carbide (SiC), and silicate‐based minerals have demonstrated the ability to synergistically encapsulate PCMs to prevent leakage, enhance thermal conductivity, and mitigate supercooling. However, the efficacy of these strategies in reducing supercooling varies, and a considerable number of studies have reported an exacerbation. Therefore, appropriate material selection and fine tuning for formulation are necessary. This review critically assesses silicon‐based materials as a component of PCM composite that have been developed over the years. Also, it presents an academic analysis of the selection of silicon‐based materials and the design strategy for PCM composites to optimize PCM formulations according to specific desired properties.
The effects of the COVID‐19 pandemic on the mental health of people with obesity
Authors: Mukhopadhyay Sankar 
Published: December 2023

AbstractObesity is a risk factor for anxiety and depression. Obesity is also a risk factor for severe COVID‐19 disease and therefore may have contributed to adverse mental health outcomes in this vulnerable population during the COVID‐19 pandemic. We compare the trajectory of mental health outcomes of people with obesity with normal‐weight people before and during the COVID‐19 pandemic using nationally representative individual‐level longitudinal data from the National Health Interview Survey and Difference‐in‐Difference regressions. Our results indicate that severe anxiety increased by 2.75 (95% CI: 0.0056–0.0494; p‐value 0.014) percentage points, representing a 31.3% relative increase, and anxiety‐related prescription drug usage increased by 2.75 (95% CI: 0.0076–0.0473; p‐value<0.01) percentage points, representing a 19.2% relative increase among people with obesity, compared to normal‐weight people. We conclude that people with obesity experienced an increase in the incidence of severe anxiety and anxiety‐related prescription drug usage during the COVID‐19 pandemic, which was not observed among normal‐weight individuals. Furthermore, women, less‐educated, and rural residents with obesity disproportionately bore the burden of the pandemic.

Published: December 2023

AbstractIn this work, a class of bubble‐containing multicompartmental particles with self‐orienting capability is developed, where a single bubble is enclosed at the top of the super‐segmented architecture. Such bubbles, driven by potential energy minimization, cause the particles to have a bubble‐upward preferred orientation in liquid, enabling efficient decoding of their high‐density signals in an interference‐resistant manner. The particle preparation involves bubble encapsulation via the impact of a multicompartmental droplet on the liquid surface and overall stabilization via rational crosslinking. The conditions for obtaining these particles are systematically investigated. Methodological compatibility with materials is demonstrated by different hydrogel particles. Finally, by encapsulating cargoes of interest, these particles have found broad applications in actuators, multiplexed detection, barcodes, and multicellular systems.
