Published: October 2022

AbstractBackgroundInnovations in machined and three‐dimensionally (3D) printed implant technology have allowed for customized complex pelvic reconstructions. We sought to determine the survivorship of custom hemipelvis reconstruction using ilium‐only fixation at a minimum 2‐year follow‐up, their modes of failure, and the postoperative complications resulting from the procedure.MethodsA retrospective review identified 12 consecutive patients treated with custom hemipelvis reconstruction. Indications for surgery were bone tumor requiring internal hemipelvectomy (four patients) or multiply revised, failed hip arthroplasty with massive bone loss (eight patients). All patients had a minimum of 2‐year follow‐up with a mean of 60.5 months. Kaplan–Meier survivorship analysis was determined for all patients. Postoperative complications and reoperations were categorized for all patients.ResultsAt a mean of 60.5 months, 11 of 12 patients had retained their custom implant (92% survivorship). One implant was removed as a result of an acute periprosthetic joint infection (PJI). There were no cases of aseptic loosening. Seven of 12 patients required reoperation (three PJI; two dislocations; two superficial wound complications), with five patients going on to reoperation‐free survival.ConclusionsCustom hemipelvis reconstruction utilizing an ilium monoflange provides durable short‐term fixation at a minimum 2‐year follow‐up. Reoperation for infection and dislocation is common.

AbstractA dielectric material is a particular type of insulator that does not conduct electricity but gets polarized when subjected to electricity, which is a crucial part of electronics such as cables, capacitors, displays, transformers, etc. Currently, synthesizing a nonpolar dielectric remains challenging. In this study, a method to make a high dielectric and nonpolar fluoropolymer and its nanocomposites based on cellulose nanocrystals (CNCs) by grafting it with nonpolar polymer 2,2,2‐trifluoroethyl methacrylate is reported. A high dielectric constant but nonpolar nanocellulose material is obtained for the first time. This material has an anisotropic arrangement of dipoles with a high polarizability effect, thereby displaying excellent dielectric properties (e.g., dielectric constant and loss: 8.59 and 0.017 at 10 kHz) and high stability (dielectric constant at 8.21 at 1 MHz). The dielectric material is miscible as an additive with other commercial fluoropolymer plastic, which demonstrates a high breakage voltage ranging from 4.6 to 9.2 kV/0.1 mm. When it is used as an interfacial layer in electrowetting display devices, it also demonstrated a low voltage driven and fast‐response effect. The excellent dielectric performances allow to develop more high‐performance dielectrics and electronics such as memories, sensors, actuators, wires, and film capacitors.
Nickel‐Aluminum Hydrotalcite for Improving Flame Retardancy and Smoke Suppression of Intumescent Flame Retardant Polypropylene: Preparation, Synergy, and Mechanism Study

Published: October 2022

AbstractIntumescent flame retardants (IFR) are widely used in the field of flame retardant polypropylene (PP), but their flame retardant efficiency and smoke suppression properties need to be further improved. Herein, a Ni‐Al LDH (layered double hydroxide) is obtained successfully by coprecipitation and microwave hydrothermal technique and used as a synergist to improve the flame‐retardant and smoke‐suppression properties of triazine‐based IFR. The results showed that IFR/Ni‐Al LDH exhibited the best synergistic effect when the IFR is replaced by 5 wt% Ni‐Al LDH. 17 wt% IFR/Ni‐Al LDH enabled the PP composites to achieve UL‐94 V‐0 rating with a high LOI of 29.8%. Besides, the introduction of Ni‐Al LDH effectively decreased the heat and smoke release of the PP/IFR composites due to its catalytic charring effect. This is mainly attributed that the introduction of metal ions in Ni‐Al LDH effectively improved the strength and crosslinking degree of char layer and promoted the formation of a cohesive and dense char layer. The formed high‐quality char layer effectively exerted the barrier effect in condensed phase. Therefore, the PP/IFR/Ni‐Al LDH composites exhibited excellent flame‐retardant and smoke‐suppression performance. This investigation provided a facile way to prepare environment‐friendly and high‐performance flame retardant PP composites with wide application prospects.
Does celebrity attachment influence brand attachment and brand loyalty in celebrity endorsement? A mixed methods study

Published: October 2022

AbstractThe study tested a celebrity endorsement model to investigate the direct and indirect influences of celebrity attachment on brand loyalty across two culturally distinct countries: The United Kingdom and Turkiye. The survey was completed by 626 respondents and the data were analyzed using structural equation modeling. The findings show that celebrity attachment positively influences actual self‐congruence, ideal self‐congruence, brand quality, and brand attachment. Brand attachment mediates the effect of celebrity attachment on brand loyalty. Furthermore, the effectiveness of the celebrity endorsement process differs between British and Turkish consumers. Our research complements the meaning transfer model as it confirms that the celebrity endorsement process is influenced by two attachment objects: celebrities and brands. A follow‐up study with text mining analysis of the consumer comments about the product reviews posted by social media influencers (SMIs) supported the validity of the celebrity endorsement model. Practitioners should consider the consumer's emotional and cognitive bonding with celebrities, and brands to enhance the effectiveness of the celebrity endorsement process. The more consumers are attached to celebrities (or SMIs) and brands, the more loyal they become to the latter.
Enhanced algebraic substructuring for symmetric generalized eigenvalue problems
Authors: Kalantzis Vassilis , Horesh Lior 
Published: October 2022

AbstractThis article proposes a new substructuring algorithm to approximate the algebraically smallest eigenvalues and corresponding eigenvectors of a symmetric positive‐definite matrix pencil . The proposed approach partitions the graph associated with into a number of algebraic substructures and builds a Rayleigh–Ritz projection subspace by combining spectral information associated with the interior and interface variables of the algebraic domain. The subspace associated with interior variables is built by computing substructural eigenvectors and truncated Neumann series expansions of resolvent matrices. The subspace associated with interface variables is built by computing eigenvectors and associated leading derivatives of linearized spectral Schur complements. The proposed algorithm can take advantage of multilevel partitionings when the size of the pencil. Experiments performed on problems stemming from discretizations of model problems showcase the efficiency of the proposed algorithm and verify that adding eigenvector derivatives can enhance the overall accuracy of the approximate eigenpairs, especially those associated with eigenvalues located near the origin.
Rheological Behavior of Concentrated GAP/ AP Propellant Suspensions Plasticized by Diglycerol Tetranitrate
Authors: Wang Yana , Wang Yi , Song Xiaolan , An Chongwei 
Published: October 2022

AbstractConcentrated GAP/AP propellant suspensions with different solid contents and molecular masses of GAP were prepared, in which diglycerol tetranitrate (DGTN) was the energetic plasticizer. The steady shear measurements were conducted using a rheometer to examine the influences of component characteristics, particle gradation and temperature on rheological behavior. Results indicate that the GAP/DGTN mixture is Newtonian viscous and concentrated GAP/AP suspensions are pseudoplastic fluids. The Ostwald ‐ De Waele model and the Arrhenius ‐ de Guzman equation are utilized to compare the pseudoplastic behavior and the viscosity‐temperature dependence of concentrated suspensions, respectively. The apparent viscosity is exponentially related to solid content and the pseudoplastic behavior gradually increases with solid content revealed by the decreasing power law index (n). Additionally, larger particle size of AP, smaller molecular mass of GAP, or lower temperature make possible the reduced apparent viscosity. Suitable particle gradation reduces the apparent viscosity to the desired value.

AbstractBackgroundThe meadow spittlebug Philaenus spumarius L. is the vector for the bacterium Xylella fastidiosa subspecies pauca, involved in olive quick decline syndrome (OQDS) in Salento (Italy). Control of P. spumarius is key to limiting transmission of the bacterium, and an innovative approach can be based on effective natural compounds and biocontrol agents. Entomopathogenic fungi are an important source of bioactive natural molecules that play a role in the relationship between microorganisms and insects.ResultsPathogenicity bioassays, performed by dipping adults of P. spumarius in either fungal culture suspension (120 mg mL−1) or cell‐free culture supernatant of Trichoderma chlorosporum GJS 91‐150, showed, respectively, 97% and 87% death within 24 h. The effect was dose‐dependent. In laboratory bioassays, the powdered fungal culture of T. chlorosporum GJS 91‐150 did not exhibit pathogenic activity when injected into nymph spittle.ConclusionsT. chlorosporum GJS 91‐150 affected the survival of P. spumarius adults. The lethal effect was not associated with the development of mycelium on the cuticle, but seems due, at least partly, to fungal metabolites released in the culture medium. The fungus tested here has good potential for the development of effective low‐environmental impact control strategies for P. spumarius and suppression of X. fastidiosa. © 2022 Society of Chemical Industry.
A novel hybrid resampling for semiconductor wafer defect bin classification
Authors: Park You‐Jin , Pan Rong , Montgomery Douglas C. 
Published: October 2022

AbstractGenerally, defective dies on semiconductor wafer maps tend to form spatial clusters in distinguishable patterns which contain crucial information on specific problems of equipment or process, thus it is highly important to identify and classify diverse defect patterns accurately. However, in practice, there exists a serious class imbalance problem, that is, the number of the defective dies on semiconductor wafer maps is usually much smaller than that of the non‐defective dies. In various machine learning applications, a typical classification algorithm is, however, developed under the assumption that the number of instances for each class is nearly balanced. If the conventional classification algorithm is applied to a class imbalanced dataset, it may lead to incorrect classification results and degrade the reliability of the classification algorithm. In this research, we consider the semiconductor wafer defect bin data combined with wafer warpage information and propose a new hybrid resampling algorithm to improve performance of classifiers. From the experimental analysis, we show that the proposed algorithm provides better classification performance compared to other data preprocessing methods regardless of classification models.

AbstractBackgroundPostoperative pancreatic fistula (POPF) represents the most feared complication after distal pancreatectomy, and the possible role of robotic assistance in this setting is poorly investigated so far.MethodsWe analysed short‐term outcomes of 88 patients who had undergone robot‐assisted distal pancreatectomy (RDP), dividing them according to pancreatic stump management: selective Wirsung duct ligation/hand sewn suture (WirsLIG group), use of robotic EndoWrist staplers (RobSTAP group), and use of laparoscopic staplers (LapSTAP group).ResultsMean operative time resulted significantly longer in WirsLIG group (291.1 ± 77.21 min vs. 245 ± 56.22 min in RobSTAP group vs. 221.77 ± 64.64 min in LapSTAP group). No significant differences were found in median hospital stay and in POPF occurrence.ConclusionsNo strategy for pancreatic stump management during RDP has proven superior to the others in reducing POPF rates. The hand‐sewn technique resulted more time consuming, nevertheless it remains essential where there is not enough space to insert the stapler.
Application and evaluation of a subaqueous soil‐landscape conceptual model in the West River subestuary, Maryland
Authors: Wessel Barret M. , Rabenhorst Martin C. , Needelman Brian A. 
Published: October 2022

AbstractA soil‐landscape conceptual model developed in the Rhode River subestuary of Maryland was applied to create a soil survey for the adjacent West River subestuary. The survey for the West River subestuary was completed before samples were collected there to evaluate the soil‐landscape conceptual model used to generate the soil survey. The West River subestuary was then sampled along transects that crossed soil map units to compare observed soil taxa with predicted soil taxa. Observed transect samples were classified and scored based on their similarity to predicted taxa in soil map units. These data were resampled via a bootstrapping method to determine if the predictions of the West River subestuary soil survey were significantly different from random predictions. Significant information was provided by the survey, and therefore by the soil‐landscape conceptual model used to generate it.
Spray‐Dried Photonic Balls with a Disordered/Ordered Hybrid Structure for Shear‐Stress Indication

Published: October 2022

AbstractOptical microscale shear‐stress indicator particles are of interest for the in situ recording of localized forces, e.g., during 3D printing or smart skins in robotic applications. Recently developed particle systems are based on optical responses enabled by integrated organic dyes. They thus suffer from potential chemical instability and cross‐sensitivities toward humidity or temperature. These drawbacks can be circumvented using photonic balls as shear‐stress indicator particles, which employ structural color as the element to record forces. Here, such photonic balls are prepared from silica and iron oxide nanoparticles via the scalable and fast spray‐drying technique. Process parameters to create photonic balls with a disordered core and an ordered particle structure toward the exterior of the supraparticles are reported. This hybrid disordered–ordered structure is responsible for a color loss of the indicator particles during shear‐stress application because of irreversible structural destruction. By adjusting the primary silica particle sizes, nearly all colors of the visible spectrum can be achieved and the sensitivity of the response to shear stress can be adjusted.

Published: October 2022

AbstractAlzheimer's disease (AD) is one of the largest health crises in the world. There are limited pharmaceutical interventions to treat AD, however, and most of the treatment options are not for cure or prevention, but rather to slow down the progression of the disease. The aim of this study was to examine the effect of tactile stimulation (TS) on AD‐like symptoms and pathology in APPNL‐G‐F/NL‐G‐F mice, a mouse model of AD. The results show that TS reduces the AD‐like symptoms on tests of cognition, motor, and anxiety‐like behaviors and these improvements in behavior are associated with reduced AD pathology in APP mice. Thus, TS appears to be a promising noninvasive strategy for slowing the onset of dementia in aging animals.

Published: October 2022

AbstractEquine coital rash (ECE) is a highly contagious benign infection that induces lesions on external genitals, and it is caused by the equine herpesvirus type 3 (EHV‐3). Although the disease is globally distributed, its presence in Chile has not been documented from a genetic point of view. Here, we performed polymerase chain reaction screenings for EHV‐3 in lesions of external genitals in four horses belonging to a riding station at Bulnes, Ñuble Region, Chile. We sequenced a fragment of the glycoprotein G (gG) gene from three horses with clinical signs of ECE. The sequences were identical between them and 99.7% similar to a haplotype of EHV‐3 detected in Brazil, and phylogenetically related with homologue from Japan, Russia and Brazil. Our results show the presence of EHV‐3 for the first time in horses with ECE in Chile.
Vegetation structure and food availability following disturbance in recently restored early successional plant communities

Published: October 2022

AbstractFields dominated by nonnative grasses, such as tall fescue (Schedonorus arundinaceus), are being restored to native plant communities across the eastern U.S. Upon restoration, disturbance is necessary to maintain native communities in an early seral stage, and plant response to different management practices is of interest to managers to guide habitat enhancement for various wildlife species. We evaluated effects of burning and mowing following restoration of native plant communities via 2 methods (planting native grasses and forbs and seedbank response without planting), across 11 replicated sites in Tennessee and Alabama, 2019–2020. We compared vegetation composition and structure, openness at ground level, forage availability, and nutritional carrying capacity (NCC) following 4 treatments (Seedbank Burned, Seedbank Mowed, Planted Burned, Planted Mowed, and tall fescue Control), and we related these measurements to the food and cover requirements for 3 popular game species: white‐tailed deer (Odocoileus virginianus), wild turkey (Meleagris gallopavo), and northern bobwhite (Colinus virginianus). The combination of planting and mowing increased grass coverage, whereas units that were established via seedbank response and managed by burning had greater forb coverage. Visual obstruction above 25 cm was greater in all treatments than Control, which provided cover that has been described as selected nesting cover by wild turkey and bedding cover for deer. Openness at ground level, which is especially important for bobwhite and wild turkey broods, was 30% greater in Seedbank Burned than Planted Mowed where we recorded the least openness among treatments by the second year of treatment. Similarly, coverage of bobwhite food and deer forage plant species was greatest in Seedbank Burned. Biomass (kg/ha) of plant species known to be selected as forage by deer was greater in all treatments than in Control, and NCC (deer days/ha) was greatest in Seedbank Burned by year 2. Our results highlight differences in plant composition and structure following management of early successional communities. Where possible, we encourage managers to use fire instead of mowing to maintain plant communities, especially if food plants and enhanced structure at multiple levels for bobwhite, wild turkey, and deer are management objectives. Furthermore, our results illustrate planting native grasses and forbs is not necessary to restore native early successional plant communities on most sites.
Value similarity and trustworthiness predict support for waterfowl management policy
Authors: Spears Jake G. , Wallen Kenneth E. , Osborne Douglas C. 
Published: October 2022

AbstractModern wildlife agencies increasingly emphasize efforts that facilitate the social feasibility of policy via cooperation and support among affected publics. Values and trust are critical components of policy support. Value similarity is an established concept that maps well to indicators of policy support whereas trustworthiness has received limited research attention, particularly in comparison to the variably defined concept of trust. We present a conceptual model that assesses the relationships among salient value similarity (SVS), trustworthiness (ability and benevolence), and support for wildlife policy in Arkansas, USA. We used structural equation modeling (SEM) to test our model among a sample of resident waterfowl hunters ≥18 years old (n = 1,596). Respondents rated the value similarity of Arkansas Game and Fish Commission (AGFC), AGFC's trustworthiness in relation to waterfowl management, and support for waterfowl policy. The measurement model fit observed data well and the structural model indicated good fit between the conceptual model and observed data. Our findings indicate SVS positively influenced perceptions of trustworthiness that, in turn, positively influenced support for waterfowl policy. The significant positive influence SVS and trustworthiness have on policy support suggest important metrics agencies can proactively track and manage among affected publics. Furthermore, knowledge of how value similarity and trustworthiness interact with policy support can help agencies target involvement and engagement processes that improve social feasibility, particularly when a policy does not correspond with current expectations but are intended to benefit the long‐term socioecological sustainability of a resource.
